     Item 5.   Other Events



     On November 1, 1995,  Cablevision Systems Corporation (the "Registrant" or
the "Company") entered into an underwriting agreement with Bear, Stearns & Co.
Inc., Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated
and Morgan Stanley & Co. Incorporated (the "Preferred Stock Underwriters")
pursuant to which the Company agreed to sell to the Preferred Stock Underwriters
12,000,000 Depositary Shares representing 1,200,000 shares of the Company's 8
1/2% Series I Cumulative Convertible Exchangeable Preferred Stock (the "Series I
Preferred Stock") with an aggregate liquidation preference of $300,000,000. The
Company also granted the Underwriters a 30-day option to purchase up to an
additional 1,800,000 Depositary Shares representing 180,000 shares of Series I
Preferred Stock solely to cover over-allotments. The Depositary Shares will be
convertible into shares of the Company's Class A Common Stock at any time on or
after January 8, 1996 at an initial conversion price of $67.44 per share of
Class A Common Stock. The Company will apply the net proceeds of the offering of
the Depositary Shares, estimated to be $290.6 million (assuming no exercise of
the over-allotment option), to the repayment of bank indebtedness and general
corporate purposes.

     On November 2, 1995, the Company entered into a purchase agreement with
Bear, Stearns & Co. Inc., Merrill Lynch & Co., Merrill Lynch Pierce Fenner &
Smith Incorporated, Morgan Stanley & Co. Incorporated and Toronto Dominion
Securities (USA) Inc. (the "Notes Underwriters") pursuant to which the Company
agreed to sell to the Notes Underwriters $300,000,000 of the Company's 9 1/4%
Senior Subordinated Notes due 2005 (the "Notes"). The Company will apply the net
proceeds of the offering of the Notes, estimated to be $292.2 million, to the
repayment of bank indebtedness and general corporate purposes.

     The Company expects to issue the Depositary Shares and the Notes on
November 7, 1995.

     applicability relating to or affecting creditors' rights and general equity
     principles (regardless of whether enforcement is considered in a proceeding
     in equity or at law); and the form of Exchange Debentures conforms in all
     material respects to the description thereof contained in the Prospectus.
 
          (vii)  The consolidated historical financial statements included or
     incorporated by reference in the Registration Statement present fairly the
     consolidated financial position of the Company and its subsidiaries as of
     the dates indicated and the consolidated results of operations and changes
     in financial position of the Company and its subsidiaries for the periods

     generally accepted accounting principles applied on a consistent basis
     throughout the periods involved.  The financial statement schedules, if
     any, included in the Registration Statement present fairly the information
     required to be stated therein.  The selected financial data included in the
     Prospectus present fairly the information shown therein and have been
     compiled on a basis consistent with that of the audited consolidated
     financial statements included or incorporated by reference in the
     Registration Statement.  The pro forma financial statements and other pro
     forma financial information included in the Prospectus present fairly the
     information shown therein, have been prepared in accordance with the
     Commission's rules and guidelines with respect to pro forma financial
     statements, have been properly compiled on the pro forma bases described

<PAGE>
 
                                       5

     Company, the assumptions used in the preparation thereof are reasonable and
     the adjustments used therein are appropriate to give effect to the
     transactions or circumstances referred to therein.

          (viii)  The Company is a corporation duly organized, validly existing
     and in good standing under the laws of the State of Delaware with power and
     authority (corporate and other) under such laws to own, lease and operate
     its properties and conduct its business as described in the Prospectus; and
     the Company is duly qualified to transact business as a foreign corporation
     and is in good standing in each other jurisdiction in which it owns or
     leases property of a nature, or transacts business of a type, that would
     make such qualification necessary, except to the extent that the failure to
     so qualify or be in good standing would not have a material adverse effect
     on the Company and its subsidiaries, considered as one enterprise.

          (ix) The subsidiaries of the Company set forth on Schedule IV are, as
     of the date hereof, all of the "Restricted Subsidiaries", as such term is
     defined under each of  (a) the indenture, dated as of April 1, 1992, for
     the Company's 10-3/4% Senior Subordinated Debentures due 2004, (b) the
     indenture, dated as of February 15, 1993, for the Company's 9-7/8% Senior
     Subordinated Debentures due 2013 and (c) the indenture, dated as of April
     1, 1993, for the Company's 9-7/8% Senior Subordinated Debentures due 2023;
     and the Bank Credit Agreement (as such term is defined in each of the
     indentures referred to in (a), (b) and (c) above).  The subsidiaries of the
     Company set forth on Schedule V are Unrestricted Subsidiaries (the
     Restricted Subsidiaries and the Unrestricted Subsidiaries are hereinafter
     referred to collectively as the "Subsidiaries").  The Subsidiaries on
     Schedules IV and V with an asterisk by their names are the only
     subsidiaries of the Company which had at December 31, 1994 assets in excess
     of 10% of the consolidated assets of the Company and its subsidiaries as at
     that date or had, in the aggregate, for the fiscal year then ended revenues
     or operating cash flow in excess of 10% of consolidated revenues or
     consolidated operating cash flow of the Company and its subsidiaries for
     such period (such Subsidiaries are referred to herein as the "Material
     Subsidiaries").  In making this determination, any subsidiary acquired
     after December 31, 1994 shall be deemed to have been acquired as of such
     date.

          (x) Each Material Subsidiary that is a corporation is duly organized,
     validly existing and in good standing under the laws of the jurisdiction of
     its incorporation with power and authority (corporate and other) under such
     laws to own, lease and operate its properties and conduct its business; and
     each such Material Subsidiary is duly qualified to transact business as a
     foreign corporation and is in good standing in each other jurisdiction in
     which it owns or leases property of a nature, or transacts business of a
     type, that would make such qualification necessary, except to the extent
     that the failure to so qualify or be in good standing would not have a
     material adverse
<PAGE>
 
                                       6

     effect on the Company and its subsidiaries, considered as one enterprise.
     All of the outstanding shares of capital stock of each Material Subsidiary
     have been duly authorized and validly issued and are fully paid and non-
     assessable and, except as disclosed on Schedule IV or V to this Agreement
     or as disclosed or contemplated by the Prospectus, are owned by the
     Company, directly or through one or more subsidiaries, free and clear of
     any pledge, lien, security interest, charge, claim, equity or encumbrance
     of any kind.

          (xi) Each of the Material Subsidiaries in which the Company or a
     subsidiary of the Company is a limited or general partner (hereinafter
     called the "Partnerships") has been duly formed and is validly existing as
     a limited or general partnership, as the case may be, under the laws of its
     jurisdiction of organization, with full power and authority to own, lease
     and operate properties and conduct its business; all necessary filings with
     respect to the formation of the Partnerships as limited or general
     partnerships (as the case may be) have been made under such laws; and each
     of the Partnerships is duly qualified to transact business and is in good
     standing in each other jurisdiction in which it owns or leases property of
     a nature, or transacts business of a type, that would make such
     qualification necessary, except to the extent that the failure to so
     qualify or be in good standing would not have a material adverse effect on
     the Company and its subsidiaries, considered as one enterprise.

          (xii)  The Company had at the date indicated a duly authorized and
     outstanding capitalization as set forth in the Prospectus under the caption
     "Capitalization - Historical"; the Preferred Stock, the Depositary Shares,
     the Exchange Debentures and the Class A Common Stock will, upon their
     respective issuances, conform in all material respects to the description
     thereof contained in the Prospectus.

          (xiii)  The Preferred Stock, represented by the Depositary Shares, has
     been duly authorized and, when such Depositary Shares are issued and
     delivered against payment therefor as provided herein, such Preferred Stock
     will be validly issued, fully paid and non-assessable; no holder of the
     Preferred Stock or the Depositary Shares will be subject to personal
     liability by reason of being such a holder; such Preferred Stock is not
     subject to the preemptive rights of any stockholder of the Company; all
     corporate action required to be taken by the Company for the authorization,
     issuance and sale of such Preferred Stock and Depositary Shares will at the
     time of the issuance thereof have been validly and sufficiently taken; such
     Depositary Shares shall, at the time of deposit of the Preferred Stock with
     the Depositary, represent the Preferred Stock free and clear of any pledge,
     lien, security interest, charge, claim, equity or encumbrance of any kind;
     the Preferred Stock will be convertible into Class A Common Stock in
     accordance with its terms and the terms of the Certificate of Designations;
     and the Exchange Debentures, if and when issued, will be convertible
<PAGE>
 
                                       7

     into Class A Common Stock in accordance with their terms and the terms of
     the Exchange Indenture.

          (xiv)  The Class A Common Stock issuable upon conversion of the
     Preferred Stock pursuant to the terms of the Certificate of Designations,
     at the time of issuance of the Preferred Stock, and the Class A Common
     Stock issuable upon conversion of the Exchange Debentures pursuant to the
     terms of the Exchange Indenture, at the time of issuance of such Exchange
     Debentures, will have been duly authorized and validly reserved for
     issuance upon such conversion by all necessary corporate action and such
     Class A Common Stock, when issued upon such conversion, will be validly
     issued, fully paid and non-assessable; and no holder thereof will be
     subject to personal liability by reason of being such a holder.

          (xv) All of the other outstanding shares of capital stock of the
     Company have been duly authorized and validly issued and are fully paid and
     non-assessable; no holder thereof is or will be subject to personal
     liability by reason of being such a holder; none of the outstanding shares
     of capital stock was issued in violation of the preemptive rights of any
     stockholder of the Company.

          (xvi)  Since the respective dates as of which information is given in
     the Registration Statement and the Prospectus, except as otherwise stated
     therein or contemplated thereby, there has not been (A) any material loss
     or interference with its business from fire, explosion, flood or other
     calamity, whether or not covered by insurance, or from any labor dispute or
     court or governmental action, order or decree and there has not been any
     change in the capital stock or long term debt of the Company or any of its
     Subsidiaries or any change which the Company has reasonable cause to
     believe will involve any material adverse change, or any development
     involving a prospective material adverse change, in or affecting the
     financial position, stockholders' equity or results of operations of the
     Company and its subsidiaries, considered as one enterprise, or (B) any
     transaction entered into by the Company or any subsidiary, other than in
     the ordinary course of business, that is material to the Company and its
     subsidiaries, considered as one enterprise, or (C) any dividend or
     distribution of any kind declared, paid or made by the Company on its
     capital stock.

          (xvii)  Neither the Company nor any Subsidiary is in default in the
     performance or observance of any obligation, agreement, covenant or
     condition contained in any contract, indenture, mortgage, loan agreement,
     note, lease or other agreement or instrument to which it is a party or by
     which it may be bound or to which any of its properties may be subject,
     except for such defaults that would not have a material adverse effect on
     the financial position, stockholders' equity or results of operations of
     the Company and its subsidiaries, considered as one enterprise.  The
     execution and delivery by the Company of the Exchange Indenture, the
     Certificate of

the terms and conditions herein set forth, the Company agrees to sell to each
Underwriter, and each Underwriter agrees, severally and not jointly, to purchase
from the Company, at the

purchase price to the Underwriters set forth in Schedule II, the principal

York, at 10:00 A.M. on such date as shall be agreed upon by the Company and you,
or as shall otherwise be provided in Section 10 (such date and time of payment
and delivery being herein called the "Initial Closing Time").  Payment shall be
made to the Company in the manner specified in Schedule II hereto, against
delivery of the Firm Shares to you for the respective accounts of the several
Underwriters, which Firm Shares are to be deposited by you with the Depositary
pursuant to the Deposit Agreement.  Depositary Receipts evidencing such
Depositary Shares that represent the Firm Shares shall be in such denominations
and registered in such names as you may request in writing at least two full
business days before the Initial Closing Time.  Such Depositary Receipts will be
made available in New York City for examination and packaging by you not later

per share to be paid by the Underwriters to the Company for the Firm Shares as
set forth in this Section 2, for the sole purpose of covering over-allotments in
the sale of Depositary Shares representing the Firm Shares by the Underwriters.
This option may be exercised at any time, in whole or in part (but not more than
once), on or before the thirtieth day following the date of the Prospectus
Supplement, by written notice by you to the Company.  Such notice shall set
forth the aggregate number of Additional Shares as to which the option is being
exercised and the date and time, as reasonably determined by you, when the
Additional Shares are to be delivered (such date and time of delivery being
herein sometimes referred to as the "Additional Closing Time"; the Initial
Closing Time and the Additional Closing Time are each hereafter referred to as a
"Closing Time"); provided, however, that the Additional Closing Time shall not
be earlier than the Initial Closing Time in respect of the Firm Shares or
earlier than the second full business day after the date on which the option
shall have been exercised nor later than the eighth full business day after the
date on which the option shall have been exercised (unless such time and date
are postponed in accordance with the provisions of Section 9 hereof).

Additional Shares shall be registered in such names and in such denominations as
you may request in writing at least two full business days prior to the

          The number of Additional Shares to be sold to each Underwriter shall
be the number which bears the same ratio to the aggregate number of Additional
Shares being purchased as the number of Firm Shares set forth opposite the name
of such Underwriter in Schedule I hereto (or such number increased as set forth
in Section 10 hereof) bears to 12,000,000, subject, however, to such adjustments
to eliminate any fractional shares as you in your sole discretion shall make.

          Payment for the Additional Shares shall be made to the Company in the
manner specified in Schedule II hereto against delivery to you of the Additional
Shares, to be purchased by you and deposited by you with the Depositary pursuant
to the Deposit Agreement, for the respective accounts of the Underwriters.

     to be delivered in connection with sales of the Depositary Shares, the
     Company will notify you immediately, and confirm the notice in writing

     Commission to amend the Registration Statement or any supplement to the
     Prospectus or for additional information relating thereto and (iv) of the
     issuance by the Commission of any stop order suspending the effectiveness
     of the Registration Statement, of the suspension of the qualification of
     the Depositary Shares for offering or sale in any jurisdiction, or of the
     institution or to the Company's knowledge, the threatening of any
     proceedings for any of such purposes.  The Company will use every
     reasonable effort to prevent the issuance of any such stop order or of any
     order preventing or suspending such use and, if any such order is issued,
     to obtain the lifting thereof at the earliest possible moment.

          (f) The Company has furnished or will furnish to you one signed copy
     for the managing Underwriters of each of the Registration Statement (as
     originally filed) and of all amendments thereto, whether filed before or
     after the Registration Statement became effective, and as many copies of
     all exhibits and documents filed therewith, including documents
     incorporated by reference into the Prospectus pursuant to Item 12 of Form
     S-3 under the 1933 Act (through the end of the period when the Prospectus
     is required by the 1933 Act to be delivered in connection with sales of the
     Depositary Shares) and signed copies of all consents and certificates of
     experts, as you may reasonably request, and has furnished or will furnish
     to each of you, as many conformed copies of the Registration Statement as
     originally filed and of each amendment thereto (including documents
     incorporated by reference into the Prospectus but without exhibits) as you
     may reasonably request.

          (g) The Company will use its reasonable best efforts, in cooperation
     with the Underwriters, to qualify the Depositary Shares, the Class A Common
     Stock and the Exchange Debentures for offering and sale under the
     applicable securities laws of such states and other jurisdictions as you
     may designate and to maintain such qualifications in effect for a period of
     not less than one year from the date hereof; provided, however, that the
                                                  --------  -------          
     Company shall not be obligated to file any general

                                       14

     consent to service of process or to qualify as a foreign corporation or as
     a dealer in securities in any jurisdiction in which it is not so qualified
     or to subject itself to taxation in respect of doing business in any
     jurisdiction in which it is not otherwise so subject.  The Company will
     file such statements and reports as may be required by the laws of each
     jurisdiction in which the Depositary Shares, the Class A Common Stock and
     the Exchange Debentures have been qualified as above provided.  The Company
     will also supply you with such information as is necessary for the
     determination of the legality of the Depositary Shares for investment under
     the laws of such jurisdictions as you may reasonably request.

          (h) The Company will make generally available to its security holders
     as soon as practicable, but not later than 45 days after the close of the
     period covered thereby (90 calendar days in the case the period corresponds
     to the fiscal year of the Company), an earnings statement of the Company
     (in form complying with the provisions of Rule 158 of the 1933 Act
     Regulations), covering a period of 12 months beginning after the effective
     date of the Registration Statement and covering a period of 12 months
     beginning after the effective date of any post-effective amendment to the
     Registration Statement but not later than the first day of the Company's
     fiscal quarter next following such effective date.

          (i) The Company will comply to the best of its ability with the 1933
     Act and the 1933 Act Regulations, the 1934 Act and the 1934 Act Regulations
     and the 1939 Act and the 1939 Act Regulations.  If at any time when the
     Prospectus is required by the 1933 Act to be delivered in connection with
     sales of the Depositary Shares any event shall occur or condition exist as
     a result of which it is necessary to amend the Registration Statement or
     amend or supplement the Prospectus in order that the Prospectus will not
     include an untrue statement of a material fact or omit to state a material
     fact necessary in order to make the statements therein not misleading in
     the light of the circumstances existing at the time it is delivered to a
     purchaser, or if it shall be necessary at any such time to amend the
     Registration Statement or amend or supplement the Prospectus in order to
     comply with the requirements of the 1933 Act or the 1933 Act Regulations,
     the Company will promptly prepare and file with the Commission, subject to
     Section 3(d), such amendment or supplement as may be necessary to correct
     such untrue statement or omission or to make the Registration Statement or
     the Prospectus comply with such requirements.

          (j) The Company will use the net proceeds received by it from the sale
     of the Depositary Shares in the manner specified in the Prospectus under
     the caption "Use of Proceeds".

          (k) For a period of three years after the Initial Closing Time, the
     Company will furnish to you copies of all annual reports, quarterly reports
     and current reports

                                       15

     filed with the Commission on Forms 10-K, 10-Q and 8-K, or such other
     similar forms as may be designated by the Commission, and such other
     documents, reports and information as shall be furnished by the Company to
     its stockholders generally.

          (l) The Company will not be or become, at any time prior to the
     expiration of three years after the Initial Closing Time, an open-end
     investment trust, unit investment trust or face-amount certificate company
     that is or is required to be registered under Section 8 of the Investment
     Company Act of 1940, as amended (the "Investment Company Act").

          (m) The Company will not, without the prior written consent of the
     Underwriters, offer, sell, contract to sell or otherwise dispose of any
     Class A Common Stock (except for shares issuable in connection with the
     acquisition of Cablevision of Boston described under "Recent Developments"
     in the Prospectus Supplement or issuable upon conversion of securities or
     exercise of warrants and options outstanding as of the date of the
     Prospectus Supplement or pursuant to employee benefit plans) or preferred
     stock (except for any Series D Preferred Stock, Series H Preferred Stock or
     the preferred stock to be issued in the Proposed V Cable Transactions) or
     warrants, rights or options exercisable at any time therefor for a period
     of 90 days after the date of this Prospectus Supplement.

          (n) The Company will use its reasonable best efforts to effect the
     listing of the Depositary Shares and the Class A Common Stock issuable in
     respect thereof on the American Stock Exchange by the Initial Closing Time.

          (o) Upon issuance and delivery, if any, of the Exchange Debentures,
     the Exchange Debentures will be convertible at the option of the holder
     into Class A Common Stock in accordance with the terms of the Exchange
     Debentures and the Exchange Indenture, and the Class A Common Stock
     issuable upon conversion of the Exchange Debentures will have been duly
     authorized and validly reserved for issuance upon such conversion by all
     necessary corporate action, and such Class A Common Stock, when issued upon
     such conversion, will be validly issued, fully paid and non-assessable.

          Section 4.  Payment of Expenses.  The Company will pay and bear all

          Section 5.  Conditions of Underwriters' Obligations.  Except as
                      ---------------------------------------            
otherwise provided in Schedule II, the obligations of the several Underwriters
to purchase and pay for the Firm Shares and the Additional Shares, if any, at
each Closing Time, that they have respectively agreed to purchase hereunder are
subject to the accuracy, as of such Closing Time, of the representations and
warranties of the Company contained herein or in certificates of any officer of
the Company or any Subsidiary delivered pursuant to the provisions hereof, to
the performance by the Company of its obligations hereunder, and to the
following further conditions:

     no proceedings for that purpose shall have been instituted or shall be
     pending or, to the knowledge of the Company, shall be contemplated by the
     Commission, and any request on the part of the Commission for additional
     information shall have been complied with to the reasonable satisfaction of
     counsel for the Underwriters.

          (b) At such Closing Time, you shall have received a signed opinion of
     Sullivan & Cromwell, counsel for the Company, dated as of such Closing
     Time, in form and substance satisfactory to counsel for the Underwriters,
     to the effect that:

               (i) The Company has been duly incorporated and is an existing
          corporation in good standing under the laws of the State of Delaware.

               (ii) The Exchange Indenture has been duly authorized, executed
          and delivered by the Company and duly qualified under the 1939 Act;

          delivered in the
<PAGE>
 
                                       17

          manner provided for in the Exchange Indenture will, constitute valid
          and legally binding obligations of the Company enforceable in
          accordance with their terms, subject to bankruptcy, insolvency,
          fraudulent transfer, reorganization, moratorium and similar laws of
          general applicability relating to or affecting creditors' rights and
          to general equity principles.

               (iii)  Upon issuance and delivery of the Preferred Stock sold by
          the Company at such Closing Time pursuant to the terms of this
          Agreement, such Preferred Stock shall be convertible at the option of
          the holder into Class A Common Stock in accordance with the terms of
          the Company's Certificate of Incorporation; the shares of Class A
          Common Stock initially issuable upon conversion of the Preferred Stock
          have been duly authorized and reserved for issuance upon such
          conversion, and such Class A Common Stock, when issued upon such
          conversion, will be validly issued, fully paid and non-assessable; the
          issuance of such shares upon such conversion will not be subject to
          preemptive rights of any stockholder of the Company under the
          Company's Certificate of Incorporation, By-laws or the Delaware
          General Corporation Law, in each case as in effect as of the Initial
          Closing Time, and no holder thereof will be subject to personal
          liability under the Company's Certificate of Incorporation, By-laws or
          the Delaware General Corporation Law, in each case as in effect as of

               (iv) The Preferred Stock sold by the Company pursuant to the
          provisions of this Agreement on such Closing Time has been duly
          authorized and validly issued and is fully paid and non-assessable; no
          holder thereof is or will be subject to personal liability under the
          Company's Certificate of Incorporation or by-laws or the Delaware
          General Corporation Law by reason of being such a holder; such
          Preferred Stock is not subject to the preemptive rights of any
          stockholder of the Company under the Company's Certificate of
          Incorporation or by-laws or the Delaware General Corporation Law.

          upon conversion of the Depositary Shares, and the compliance by the
          Company with the terms of this Agreement and the Deposit Agreement do
          not and will not result in any violation of the Certificate of
          Incorporation or By-laws of the Company, in each case as in effect as
          of the Initial Closing Time; and all regulatory consents,
          authorizations, approvals and filings required to be obtained or made
          by the Company under the Federal laws of the United States, the laws
          of the State of New York and the General Corporation Law of the State
          of Delaware
<PAGE>
 
                                       18

          for the issuance, sale and delivery of the Depositary Shares by the
          Company to the Underwriters have been obtained or made.
 
               (vi) This Agreement has been duly authorized, executed and
          delivered by the Company.

               (vii)  the Deposit Agreement has been duly authorized, executed
          and delivered by the Company and, assuming due authorization,
          execution and delivery thereof by the Depositary, constitutes a legal,
          valid and binding obligation of the Company, enforceable against the
          Company in accordance with its terms, subject to bankruptcy,
          insolvency, fraudulent transfer, reorganization, moratorium and
          similar laws of general applicability relating to or affecting
          creditors' rights and to general equity principles.

               Such counsel shall also furnish you with a letter to the effect
     that as counsel to the Company, they reviewed the Registration Statement
     and the Prospectus, participated in discussions with representatives of the
     Underwriters and of the Company and its accountants and advised the Company
     as to the requirements of the 1933 Act and the applicable rules and
     regulations thereunder; between the date of the Prospectus Supplement and
     such Closing Time, such counsel participated in further discussions with
     representatives of the Underwriters and of the Company and its accountants
     in which the contents of certain portions of the Prospectus and related
     matters were discussed and reviewed certain documents filed by the Company
     with the Commission, certificates of certain officers of the Company, an
     opinion addressed to the Underwriters from Robert S. Lemle, Esq. and a
     letter from the Company's independent accountants; on the basis of the
     information that such counsel gained in the course of the performance of
     the services referred to above, considered in the light of such counsel's
     understanding of the applicable law (including the requirements of Form S-3
     and the character of the prospectus contemplated thereby) and the
     experience such counsel have gained through their practice under the 1933
     Act, they confirm to you that, in such counsel's opinion, the Registration
     Statement and the Prospectus, and each amendment or supplement thereto, as
     of their respective effective or issue dates appeared on their face to be
     appropriately responsive in all material respects to the requirements of
     the 1933 Act, the 1939 Act, and the applicable rules and regulations of the
     Commission thereunder; further, nothing that came to such counsel's
     attention in the course of such review has caused such counsel to believe
     that any part of the Registration Statement, when such part became
     effective, contained any untrue statement of a material fact or omitted to
     state any material fact required to be stated therein or necessary to make
     the statements therein not misleading or that the Prospectus as of the date
     of the Prospectus Supplement contained any untrue statement of a material
     fact or omitted to state any material fact necessary in order to make the
     statements therein, in the light of the circumstances
<PAGE>
 
                                       19

     under which they were made, not misleading; also, nothing that came to the
     attention of such counsel in the course of the procedures described in the
     second clause of this paragraph has caused such counsel to believe that the
     Prospectus, as supplemented by the Prospectus Supplement, as of such
     Closing Time, contained any untrue statement of a material fact or omitted
     to state any material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading; such counsel shall state that the limitations inherent in the
     independent verification of factual matters and the character of
     determinations involved in the registration process are such that such
     counsel does not assume any responsibility for the accuracy, completeness
     or fairness of the statements contained in the Registration Statement or
     the Prospectus except for those made under the captions "Description of
     Series I Preferred Stock", "Description of Exchange Debentures",
     "Description of Depositary Shares", "Description of Common Stock -- Class A
     Common Stock and Class B Common Stock" and "Underwriting" in the Prospectus
     insofar as they relate to provisions of documents therein described; also,
     such counsel need express no opinion or belief as to the financial
     statements or other financial data contained in the Registration Statement
     or the Prospectus, or as to the description of statutes, regulations,
     proceedings or matters referred to in Section 5(d) hereof.

               In rendering such opinion, such counsel may state that they
     express no opinion as to the laws of any jurisdiction other than the
     Federal laws of the United States, the laws of the State of New York and
     the General Corporation Law of the State of Delaware and no opinion as to
     federal or state communications laws.  Such counsel may also state that,
     insofar as such opinion involves factual matters, they have relied, to the
     extent they deem proper, upon certificates of officers of the Company and
     the Subsidiaries and certificates of public officials.

          (c) At such Closing Time you shall have received a signed opinion of
     Robert S. Lemle, Esq., Executive Vice President, Secretary and General
     Counsel for the Company, in form and substance satisfactory to counsel to
     the Underwriters, to the effect that:

               (i) The Company is a corporation duly organized, validly existing
          and in good standing under the laws of the State of Delaware with
          corporate power and authority under such laws to own, lease and
          operate its properties and conduct its business as described in the
          Prospectus.

               (ii) The Company is duly qualified to transact business as a
          foreign corporation and is in good standing in each other jurisdiction
          in which it owns or leases property of a nature, or transacts business
          of a type, that would make such qualification necessary, except where
          the failure to be so qualified would
<PAGE>
 
                                       20

          not have a material adverse effect on the Company and its
          subsidiaries, considered as one enterprise.

               (iii)   Each Material Subsidiary that is a corporation is duly
          incorporated, validly existing and in good standing under the laws of
          the jurisdiction of its incorporation, with corporate power and
          authority under such laws to own, lease and operate its properties and
          conduct its business.  Each Material Subsidiary that is a partnership
          is duly organized under the laws of the jurisdiction of its
          organization.

               (iv) The number of authorized shares of Capital Stock of the
          Company is as set forth in the Prospectus under the heading
          "Capitalization".

               (v) All of the outstanding shares of capital stock of each
          Material Subsidiary have been duly authorized and validly issued and
          are fully paid and nonassessable; except as set forth on Schedules IV
          and V to this Agreement or as disclosed in or as contemplated by the
          Prospectus, all of such shares are owned by the Company, directly or
          through one or more subsidiaries, free and clear of any material
          pledge, lien, security interest, charge, claim, equity or encumbrance
          of any kind; no holder thereof is subject to personal liability under
          the certificate of incorporation or by-laws of the respective Material
          Subsidiary or the corporation law of the jurisdiction in which such
          Material Subsidiary is organized by reason of being such a holder and
          none of such shares was issued in violation of the preemptive rights
          of any stockholder of such Material Subsidiary under the certificate
          of incorporation or by-laws of such Material Subsidiary or the
          corporation law of the jurisdiction in which such Material Subsidiary
          is organized.

               (vi) To such counsel's knowledge, there are no legal or
          governmental proceedings pending or threatened to which the Company or
          any of its subsidiaries is or may be a party, or of which any of their
          properties are or may be the subject, of a character which are
          required to be disclosed in the Registration Statement, the
          Prospectus, the annual Form 10-K or any Form 10-Q of the Company,
          other than those disclosed therein.

               (vii)  The documents incorporated by reference in the Prospectus
          or any further amendment or supplement thereto made by the Company
          prior to such Closing Time (other than the financial statements and
          related schedules therein and any untrue statement or omission of a
          material fact contained therein which was corrected in the Prospectus,
          as to which such counsel need express no opinion), when they became
          effective or were filed with the Commission, as the case may be,
          complied as to form in all material respects
<PAGE>
 
                                       21

          with the requirements of the Exchange Act and the rules and
          regulations of the Commission thereunder; and he has no reason to
          believe that such documents considered together as of the date of the
          Prospectus Supplement or as of such Closing Time contained or contains
          an untrue statement of a material fact or omitted or omits to state a
          material fact necessary in order to make the statements therein, in
          the light of the circumstances under which they were made, not
          misleading.

               (viii)  Such counsel does not know of any contracts or documents
          of a character required to be described or referred to in the
          Registration Statement or the Prospectus or to be filed as exhibits to
          the Registration Statement that are not described, referred to or
          filed as required.

               (ix) To the knowledge of such counsel, no default exists in the
          performance or observance of any material obligation, agreement,
          covenant or condition contained in any contract, indenture, loan
          agreement, note, lease or other agreement or instrument that is
          described or referred to in the Registration Statement or the
          Prospectus or filed as an exhibit to the Registration Statement or any
          subsequent Form 10-Q of the Company, which default would have a
          material adverse effect on the financial position, stockholders'
          equity or results of operations of the Company and its subsidiaries,
          considered as one enterprise.

               (x) The execution and delivery by the Company of the Operative
          Documents, the issuance, sale and delivery of the Depositary Shares
          sold by the Company pursuant to the provisions of this Agreement on
          such Closing Time, the issuance and delivery of the Class A Common
          Stock upon conversion of the Depositary Shares, the consummation by
          the Company of the transactions contemplated by this Agreement and the
          compliance by the Company with the terms of this Agreement and the
          Deposit Agreement, will not conflict with the terms or provisions of,
          or constitute a default under, any indenture, mortgage, deed of trust,
          loan agreement or other agreement or instrument (including any
          franchise agreement, license, permit or other governmental
          authorization granted by the FCC, The State of New York Commission on
          Cable Television, or any other Federal or New York State governing
          body having jurisdiction over cable television operations) known to
          such counsel to which the Company or any Subsidiary is a party or by
          which the Company or any Subsidiary is bound or to which any of the
          property or assets of the Company or any Subsidiary is subject, which
          conflict, breach, violation or default would have a material adverse
          effect on the financial position, stockholders' equity or results of
          operations of the Company and its subsidiaries, taken as a whole, nor
          will such action result in any violation of
<PAGE>
 
                                       22

          the provisions of the Certificate of Incorporation or By-laws of the
          Company or any Federal, New York or Delaware General Corporation Law
          statute or any order, rule or regulation known to such counsel of any
          Federal, New York or Delaware court or governmental agency or body
          having jurisdiction over the Company or any Subsidiary or any of their
          properties, which violation in each case would have a material adverse
          effect on the financial position, stockholders' equity or results of
          operations of the Company and its subsidiaries, taken as a whole; and
          no consent, approval, authorization, order, registration or
          qualification of or with any such court or governmental agency or body
          is required for the issue and sale of the Depositary Shares, or the
          consummation by the Company of the transactions contemplated by this
          Agreement, except with respect to such consents, approvals,
          authorizations, registrations or qualifications as may be required
          under state or foreign securities laws in connection with the purchase
          and distribution of the Depositary Shares by the Underwriters.

               (xi) All of the other outstanding shares of capital stock of the
          Company have been duly authorized and validly issued and are fully
          paid and non-assessable; and none of the outstanding shares of capital
          stock of the Company was issued in violation of the preemptive rights
          of any stockholder of the Company under the Company's Certificate of
          Incorporation or By-Laws or the Delaware General Corporation Law.

          In rendering such opinion, such counsel may state that he expresses no
opinion as to the laws of any jurisdiction other than the Federal laws of the
United States (other than federal communications laws, as to which such counsel
need express no opinion), the laws of the State of New York and the General
Corporation Law of the State of Delaware.  In giving such opinion, such counsel
may rely, as to all matters governed by the laws of any other jurisdiction, upon
opinions of other counsel, who shall be counsel satisfactory to counsel for the
Underwriters, in which case the opinion shall state that he believes you and he
are entitled to so rely.  Such counsel may also state that, insofar as such
opinion involves factual matters, he has relied, to the extent he deems proper,
upon certificates of officers of the Company and the Subsidiaries and
certificates of public officials.

          (d) At such Closing Time you shall have received a signed opinion of
     Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., as special
     communications counsel to the Company, in form and substance satisfactory
     to counsel to the Underwriters, to the effect that:

               (i) The approvals, if any, required to be obtained from the FCC
          to consummate the transactions contemplated by this Agreement have
          been obtained and are in full force and effect.
<PAGE>
 
                                       23

               (ii) Such counsel does not know of any federal communications and
          copyright statutes that are principally directed to the regulation of
          cable properties applicable to the Company that are not described in
          the Prospectus but would be material and relevant to the business of
          the Company, and the descriptions in the Prospectus of such statutes
          therein described are accurate and fairly summarize the information
          shown.

               (iii)  The information in the Registration Statement and
          Prospectus under the captions "Risk Factors -- Risk Related to Cable
          Regulation", "Risk Factors -- Risk of Competition", "Risk Factors --
          Competition from Telephone Companies" and in the 1994 Form 10-K under
          the captions "Business -- Cable Television Operations -- Regulation",
          to the extent that such sections describe statutes, regulations and
          governmental proceedings or matters involving federal communications
          and copyright law and policy and the impact thereof on the business in
          which the Company and its subsidiaries are engaged, has been reviewed
          by them and fairly represents the communications and copyright law
          applicable to the Company and its subsidiaries as disclosed in the
          Prospectus.

     In giving such opinion, such counsel may rely, as to all matters governed
     by the laws of jurisdictions other than the law of the District of
     Columbia, the federal law of the United States and the corporate law of the
     State of Delaware, upon opinions of other counsel, who shall be counsel
     satisfactory to counsel for the Underwriters, in which case the opinion
     shall state that they believe you and they are entitled to so rely.  Such
     counsel may also state that, insofar as such opinion involves factual
     matters, they have relied, to the extent they deem proper, upon
     certificates of officers of the Company and the Subsidiaries and
     certificates of public officials.

          (e) An opinion, dated the Closing Time, of counsel for the Depositary,
     in form and substance satisfactory to the Underwriter and its counsel, to
     the effect that:

               (i) The Depositary has been duly organized and is validly
          existing as an Illinois banking corporation in good standing under
          applicable law, with full power, authority and legal right under such
          law to execute, deliver and carry out the terms of the Deposit
          Agreement; and

               (ii) The Deposit Agreement has been duly authorized, executed and
          delivered by the Depositary, and assuming due authorization, execution
          and delivery thereof, by the Company, the Deposit Agreement
          constitutes a legal, valid and binding obligation of the Depositary,
          enforceable against the Depositary in accordance with its terms,
          except as enforcement thereof may be limited by bankruptcy,
          insolvency, reorganization or other similar laws
<PAGE>
 
                                       24

          affecting enforcement of creditors' rights generally and except as
          enforcement thereof is subject to general principles of equity
          (regardless of whether enforcement is considered in a proceeding in
          equity or at law); and the Depositary Receipts have been duly
          authorized, executed and delivered by the Depositary pursuant to the
          Deposit Agreement.

          (f) At such Closing Time, you shall have received the favorable
     opinion of Shearman & Sterling, counsel for the Underwriters, dated as of
     such Closing Time, to the effect that the opinions delivered pursuant to
     Sections 5(b), 5(c) and 5(d) appear on their face to be appropriately
     responsive to the requirements of this Agreement except, specifying the
     same, to the extent waived by you, and with respect to the incorporation
     and legal existence of the Company, the Preferred Stock sold by the Company
     pursuant to this Agreement, this Agreement, the Deposit Agreement, the
     Exchange Indenture, the Registration Statement, the Prospectus, the
     documents incorporated by reference and such other related matters as you
     may require.  In rendering such opinion, such counsel may state that they
     express no opinion as to the laws of any jurisdiction other than the
     Federal laws of the United States, the laws of the State of New York and
     the General Corporation Law of the State of Delaware, and no opinion as to
     federal or state communications laws.  Such counsel may also state that,
     insofar as such opinion involves factual matters, they have relied, to the
     extent they deem proper, upon certificates of officers of the Company and
     the Subsidiaries and certificates of public officials.

          (g) At such Closing Time, (i) the Registration Statement and the
     Prospectus, as they may then be amended or supplemented, shall contain all
     statements that are required to be stated therein under the 1933 Act and
     the 1933 Act Regulations and, in all material respects, shall conform to
     the requirements of the 1933 Act and the 1933 Act Regulations and the 1939
     Act and the 1939 Act Regulations and neither the Registration Statement nor
     the Prospectus, as they may then be amended or supplemented, shall contain
     an untrue statement of a material fact or omit to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, (ii) there shall not have been, since the respective dates
     as of which information is given in the Registration Statement, any
     material adverse change or any development involving a prospective material
     adverse change in or affecting the financial position, stockholders' equity
     or results of operations of the Company and its subsidiaries, considered as
     one enterprise, (iii) the Company shall have complied with all agreements
     and satisfied all conditions on its part to be performed or satisfied at or
     prior to such Closing Time and (iv) the other representations and
     warranties of the Company set forth in Section 1(a) shall be accurate as
     though expressly made at and as of such Closing Time. At such Closing Time,
     you shall have received a certificate of the Chief Executive Officer, the
<PAGE>
 
                                       25

     President, a Vice Chairman or a Vice President, and the Treasurer or
     Controller, of the Company, dated as of such Closing Time, to such effect.

          (h) You shall have received the letter or letters specified in
     Sections 1 and 2 of Schedule III at the date hereof and the letter
     specified in Section 3 of Schedule III at such Closing Time, as well as a
     letter from Deloitte & Touche LLP dated as of the date hereof substantially
     in the form annexed to Schedule III.

          (i) Unless otherwise specified in Schedule II hereto, on or after the
     date hereof (i) no downgrading shall have occurred in the rating accorded
     the Company's debt securities by any "nationally recognized statistical
     rating organization," as that term is defined by the Commission for
     purposes of Rule 436(g)(2) under the Act and (ii) no such organization
     shall have publicly announced that it has under surveillance or review,
     with possible negative implications, its rating of any of the Company's
     debt securities.

          (j) At such Closing Time, counsel for the Underwriters shall have been
     furnished with all such documents, certificates and opinions as they may
     reasonably request for the purpose of enabling them to pass upon the
     issuance and sale of the Preferred Stock and the Depositary Shares as
     herein contemplated and the matters referred to in Section 5(f) and in
     order to evidence the accuracy and completeness of any of the
     representations, warranties or statements of the Company, the performance
     of any of the covenants of the Company, or the fulfillment of any of the
     conditions herein contained.

          (k) At such Closing Time, the Depositary Shares and the Class A Common
     Stock issuable upon conversion thereof have been duly authorized for
     listing by the American Stock Exchange.

          If any of the conditions specified in this Section 5 shall not have
been fulfilled when and as required by this Agreement to be fulfilled, this
Agreement may be terminated by you on notice to the Company at any time at or
prior to such Closing Time, and such termination shall be without liability of
any party to any other party.  Notwithstanding any such termination, the
provisions of Sections 6, 7 and 8 shall remain in effect.

          Section 6.  Indemnification.  (a)  The Company agrees to indemnify and
                      ---------------                                           
hold harmless each Underwriter and each person, if any, who controls any
Underwriter within the meaning of Section 15 of the 1933 Act as follows:

          (i) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of an untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     (or any amendment thereto),
<PAGE>
 
                                       26

     including all documents incorporated therein by reference, or the omission
     or alleged omission therefrom of a material fact required to be stated
     therein or necessary to make the statements therein not misleading or
     arising out of an untrue statement or alleged untrue statement of a
     material fact included in any preliminary prospectus supplement or the
     Prospectus (or any amendment or supplement thereto) or the omission or
     alleged omission therefrom of a material fact necessary in order to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading;

          (ii) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, if such settlement is effected with
     the written consent of the Company; and

          (iii)  against any and all expense whatsoever, as incurred (including
     fees and disbursements of counsel chosen by you), reasonably incurred in
     investigating, preparing or defending against any litigation, or
     investigation or proceeding by any governmental agency or body, commenced
     or threatened, or any claim whatsoever based upon any such untrue statement
     or omission, or any such alleged untrue statement or omission, to the
     extent that any such expense is not paid under subparagraph (i) or (ii)
     above;

provided, however, that this indemnity agreement does not apply to any loss,
- --------  -------                                                           
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
Underwriter through you expressly for use in the Registration Statement (or any
amendment thereto) or any preliminary prospectus supplement or the Prospectus
(or any amendment or supplement thereto).

          The foregoing indemnity with respect to any untrue statement contained
in or any omission from the preliminary prospectus supplement, shall not inure
to the benefit of any Underwriter (or any person controlling such Underwriter)
on account of any loss, claim, damage, liability or litigation arising from the
sale of Depositary Shares to any person by such Underwriter if such Underwriter
failed to send or give a copy of the Prospectus, as the same may be supplemented
or amended, to such person within the time required by the 1933 Act, and the
untrue statement or alleged untrue statement or omission or alleged omission of
a material fact in such preliminary prospectus supplement was corrected in the
Prospectus, unless such failure resulted from noncompliance by the Company with
its obligations hereunder to furnish the Underwriters with copies of the
Prospectus.
<PAGE>
 
                                       27

          (b) Each Underwriter severally agrees to indemnify and hold harmless
the Company, its directors, each of its officers who signed the Registration
Statement, and each person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act, against any and all loss, liability, claim,
damage and expense described in the indemnity agreement in Section 6(a), as
incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment thereto) or any preliminary prospectus supplement or the Prospectus
(or any amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Company by such Underwriter through you
expressly for use in the Registration Statement (or any amendment thereto) or
such preliminary prospectus supplement or the Prospectus (or any amendment or
supplement thereto).

          (c) Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, but failure to so notify an indemnifying
party shall not relieve it from any liability which it may have otherwise than
on account of this indemnity agreement.  An indemnifying party may participate
at its own expense in the defense of such action.  In no event shall the
indemnifying party or parties be liable for the fees and expenses of more than
one counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances.

          Section 7.  Contribution.  In order to provide for just and equitable
                      ------------                                             
contribution in circumstances under which the indemnity provided for in Section
6 is for any reason held to be unenforceable by the indemnified parties although
applicable in accordance with its terms, the Company and the Underwriters shall
contribute to the aggregate losses, liabilities, claims, damages and expenses of
the nature contemplated by such indemnity incurred by the Company and one or
more of the Underwriters, as incurred, in such proportions that the Underwriters
are responsible for that portion represented by the percentage that the
underwriting discount hereunder with respect to the offering of the Depositary
Shares bears to the purchase price of the Depositary Shares, and the Company is
responsible for the balance; provided, however, that no person guilty of
                             --------  -------                          
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation.  For purposes of this Section, each person,
if any, who controls an Underwriter within the meaning of Section 15 of the 1933
Act shall have the same rights to contribution as such Underwriter, and each
director of the Company, each officer of the Company who signed the Registration
Statement, and each person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act shall have the same rights to contribution as the
Company.

          Section 8.  Agreements to Survive Delivery.  The indemnities,
                      ------------------------------                   
agreements and other statements of the Company or its officers set forth in or
made pursuant to this Agreement will remain operative and in full force and
effect regardless of any investigation made by or on behalf of the Company, any
Underwriter or any person who controls the Company or any Underwriter within the
meaning of Section 15 of the 1933 Act and will survive delivery of and payment
for the Depositary Shares.

          Section 9.  Termination of Agreement.  (a)  You may terminate this
                      ------------------------                              
Agreement, by notice to the Company, at any time at or prior to the Closing Time
(i) if there has been, since the respective dates as of which information is
given in the Registration Statement, any material adverse change or any
development involving a prospective material adverse change in or affecting the
financial position, stockholders' equity or results of operations of the Company
and its subsidiaries, considered as one enterprise, or (ii) if there has
occurred any outbreak or escalation of hostilities or other calamity or crisis
the effect of which on the financial markets of the United States is such as to
make it, in your judgment, impracticable to market the Depositary Shares or
enforce contracts for the sale of the Depositary Shares or (iii) if trading in
any securities of the Company has been suspended by the Commission, the National
Association of Securities Dealers, Inc. or the American Stock Exchange, or if
trading generally on the American Stock Exchange or the New York Stock Exchange
or in the over-the-counter market has been suspended, or minimum or maximum
prices for trading have been fixed, or maximum ranges for prices for securities
have been required, by such exchange or by order of the Commission, the National
Association of Securities Dealers, Inc. or any other governmental authority or
(iv) if a banking moratorium has been declared by either federal or New York
authorities.

          (b) Notwithstanding any such termination, the provisions of Sections
6, 7 and 8 shall remain in effect.

          Section 10.  Default.  If one or more of the Underwriters shall fail
                       -------                                                
at the Initial Closing Time or on the Additional Closing Time, as the case may
be, to purchase the Firm Shares or Additional Shares hereunder that it or they
are obligated to purchase (the "Defaulted Depositary Shares"), you shall have
the right, within 24 hours thereafter, to make arrangements for one or more of
the non-defaulting Underwriters, or any other underwriters, to purchase all, but
not less than all, of the Defaulted Depositary Shares in such amounts as may be
agreed upon and upon the terms herein set forth; if, however, you have not
completed such arrangements within such 24-hour period, then:

          (a) if the aggregate number of Defaulted Depositary Shares does not
     exceed 10% of the aggregate number of shares of the Firm Shares or
     Additional Shares, as the case may be, to be purchased pursuant to this
     Agreement, the non-defaulting Underwriters shall be obligated to purchase
     the full amount thereof in the respective proportions that the number of
     Firm Shares or Additional Shares set
<PAGE>
 
                                       29

     forth opposite the names of such non-defaulting Underwriters in Schedule I
     bear to the total aggregate number of shares of Firm Shares or Additional
     Shares set forth opposite the names of such non-defaulting Underwriters, or

          (b) if the aggregate number of Defaulted Depositary Shares exceeds 10%
     of the aggregate number of Firm Shares or Additional Shares to be
     purchased, this Agreement shall terminate without liability on the part of
     any non-defaulting Underwriter.

          No action taken pursuant to this Section shall relieve any defaulting
Underwriter from liability in respect of its default.

          In the event of any such default that does not result in a termination
of this Agreement, either you or the Company shall have the right to postpone
the Closing Time for a period not exceeding seven days in order to effect any
required changes in the Registration Statement or Prospectus or in any other
documents or arrangements.  As used herein, the term "Underwriter" includes any
person substituted for an Underwriter under this Section 10.

          Section 11.  Notices.  All notices and other communications under this
                       -------                                                  
Agreement shall be in writing and shall be deemed to have been duly given if

for the benefit of the several Underwriters, the Company and, to the extent
expressed, any person who controls the Company or any of the Underwriters within
the meaning of Section 15 of the 1933 Act, and the directors of the Company, its
officers who have signed the Registration Statement, and their respective
executors, administrators, successors and assigns and, subject to the provisions
of Section 10, no other person shall acquire or have any right under or by
virtue of this Agreement.  The term "successors and assigns" shall not include
any purchaser, as such purchaser, from any Underwriter of the Depositary Shares.
If there are two or more Underwriters, all of their obligations hereunder are
several and not joint.

          Section 13.  Governing Law and Time.  This Agreement shall be governed

           MATTERS TO BE COVERED BY LETTER OR LETTERS OF INDEPENDENT
                               PUBLIC ACCOUNTANTS


          KPMG Peat Marwick, LLP shall have furnished to you the following
letter or letters (in each case in form and substance satisfactory to you):

          (1) At the date hereof, a letter to the effect that:

               (a) they are independent accountants with respect to the Company
          and its subsidiaries within the meaning of the 1933 Act and the
          applicable published 1933 Act Regulations;

               (b) in their opinion, except as disclosed in the Registration
          Statement, the audited consolidated financial statements and the
          related financial statement schedules of the Company and its
          subsidiaries included or incorporated by reference in such annual
          report on Form 10-K comply as to form in all material respects with
          the applicable accounting requirements of the 1933 Act as it applies
          to registration statements on Form S-3 and the related published 1933
          Act Regulations and of the 1934 Act as it applies to Form 10-K and the
          related published 1934 Act Regulations; and

               (c) in addition to their examinations, inspections, inquiries and
          other procedures referred to therein, they have performed such other
          procedures, specified by you, not constituting an audit, as they have
          agreed to perform and report on with respect to certain amounts,
          percentages, numerical data and other financial information in the
          Form 10-K and have compared certain of such amounts, percentages,
          numerical data and financial information with, and have found such
          items to be in agreement with or derived from, the detailed accounting
          records of the Company and its subsidiaries.

          (2) At the date hereof, a letter with respect to each of the Company's
     quarterly reports on Form 10-Q (a "10-Q Letter") filed prior to the date
     hereof and subsequent to the Company's most recently filed annual report on
     Form 10-K, to the effect that:

               (a) they reaffirm as of the date of such letter (and as though
          made on the date of such letter) all statements made in the 10-K
          Letter, except that the procedures specified therein shall have been
          carried out to a specified date not more than five days prior to the
          date of such 10-Q Letter;
<PAGE>
 
                                     III-2

               (b) on the basis of procedures (but not an examination in
          accordance with generally accepted auditing standards) consisting of:

                    (i) a reading of minutes of all meetings of the stockholders
               and directors of the Company and its subsidiaries and the
               __________ and ___________ Committees of the Company's Board of
               Directors and any subsidiary committees from the date of the
               latest audited consolidated financial statements to the specified
               date referred to in Section 2(a);

                    (ii) a reading of the unaudited condensed consolidated
               financial statements of the Company and its subsidiaries included
               in the quarterly report on Form 10-Q dated the date of such 10-Q
               Letter;

                    (iii)  inquiries of certain officials of the Company and its
               subsidiaries; and

          nothing came to their attention that caused them to believe that the
          unaudited condensed consolidated financial statements included in such
          quarterly report on Form 10-Q do not comply as to form in all material
          respects with the applicable accounting requirements of the 1934 Act
          as it applies to Form 10-Q and the related published 1934 Act
          Regulations or that any material modifications should be made to the
          unaudited condensed consolidated financial statements included in such
          quarterly report for them to be in conformity with generally accepted
          accounting principles, except as disclosed in the notes to such
          unaudited condensed consolidated financial statements or as otherwise
          described in such 10-Q Letter;

               (c) in addition to their examinations, inspections, inquiries and
          other procedures referred to therein, they have performed such other
          procedures, specified by you, not constituting an audit, as they have
          agreed to perform and report on with respect to certain amounts,
          percentages, numerical data and other financial information in the
          Form 10-Q and have compared certain of such amounts, percentages,
          numerical data and financial information with, and have found such
          items to be in agreement with or derived from, the detailed accounting
          records of the Company and its subsidiaries.

          (3) At the Closing Time, a letter dated the Closing Time (the "Closing
     Letter"), to the effect that:

               (a) they reaffirm as of the date of the Closing Letter (and as
          though made on the date of the Closing Letter) all statements made in
          the 10-K Letter and in each 10-Q Letter, if any, except that the
          procedures specified therein shall have been carried out to a
          specified date not more than five days prior to the date of the
          Closing Letter;
<PAGE>

                                     III-3
 
               (b) based on the procedures set forth in Section 2(b) (but
          carried out to the specified date referred to in Section 3(a)),
          nothing came to their attention that caused them to believe that, from
          the date of the latest balance sheet of the Company and its
          subsidiaries included or incorporated by reference in the Prospectus
          to such specified date, there were any increases or decreases in
          financial statement amounts specified by you as they have agreed to
          perform; and

               (c) in addition to their examinations, inspections, inquiries and
          other procedures referred to therein, they have performed such other
          procedures, specified by you, not constituting an audit, as they have
          agreed to perform and report on with respect to certain amounts,
          percentages, numerical data and other financial information in the
          Registration Statement, the Prospectus and the exhibits to the
          Registration Statement or in the documents incorporated by reference
          in the Prospectus, and have compared certain of such amounts,
          percentages, numerical data and financial information with, and have
          found such items to be in agreement with or derived from, the detailed
          accounting records of the Company and its subsidiaries.

To the Underwriters named in Schedule I



Ladies and Gentlemen:

      Cablevision Systems Corporation, a Delaware corporation (the "Company"),
proposes to issue and sell to the underwriters named in Schedule I certain of
its debt securities specified in Schedule II (the "Offered Securities") on the
terms and conditions stated herein and in Schedule II.  The Offered Securities
will be issued pursuant to an indenture to be dated as of November 1, 1995 (the
"Subordinated Indenture") between the Company and The Bank of New York, as
trustee (the "Subordinated Trustee").  As used herein, unless the context
otherwise requires, the term "Underwriters" shall mean the firms named as
Underwriters in Schedule I, and the term "you" shall mean the Underwriters.  The
Offered Securities and the Subordinated Indenture are more fully described in
the Prospectus and the Prospectus Supplement referred to below.

      The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (Registration No. 33-62313),
including a prospectus, relating to certain of its securities (including the
Offered Securities) and the offering thereof from time to time in accordance
with Rule 415 under the Securities Act of 1933, as amended (the "1933 Act").
Such registration statement has been declared effective by the Commission.  As
provided in Section 3(a), a prospectus supplement reflecting the terms of the
Offered Securities, the terms of the offering thereof and the other matters set
forth therein has been prepared and will be filed pursuant to Rule 424 under the
1933 Act.  Such prospectus supplement, in the form first filed after the date
hereof pursuant to Rule 424(b), is herein referred to as the "Prospectus
Supplement".  Such registration statement, as amended at the date hereof,
including the exhibits thereto and the documents
<PAGE>
 
                                       2

incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933
Act, is herein called the "Registration Statement", and the basic prospectus
included therein relating to all offerings of securities under the Registration
Statement, as supplemented by the Prospectus Supplement, is herein called the
"Prospectus", except that, if such basic prospectus is amended or supplemented
on or prior to the date on which the Prospectus Supplement is first filed
pursuant to Rule 424, the term "Prospectus" shall refer to the basic prospectus
as so amended or supplemented and as supplemented by the Prospectus Supplement,
in either case including the documents filed by the Company with the Commission
pursuant to the Securities Exchange Act of 1934, as amended (the "1934 Act"),
that are incorporated by reference therein pursuant to Item 12 of Form S-3 under
the 1933 Act.

      Section 1.  Representations and Warranties.  (a)  The Company represents
                  ------------------------------                              
and warrants to and agrees with each of the Underwriters that:

          (i) The Company meets the requirements for use of Form S-3 under the
     1933 Act and on the original effective date of the Registration Statement
     and on the effective date of the most recent post-effective amendment
     thereto, if any, the Registration Statement complied in all material
     respects with the requirements of the 1933 Act and the rules and
     regulations of the Commission thereunder (the "1933 Act Regulations"), the
     Trust Indenture Act of 1939, as amended (the "1939 Act") and the rules and
     regulations of the Commission under the 1939 Act (the "1939 Act
     Regulations") and did not contain an untrue statement of a material fact or
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein not misleading; on the date hereof and at the
     Closing Time (as defined below), (A) the Registration Statement and any
     amendments and supplements thereto, comply and will comply in all material
     respects with the requirements of the 1933 Act, the 1933 Act Regulations,
     the 1939 Act and the 1939 Act Regulations, (B) neither the Registration
     Statement nor any amendment or supplement thereto includes or will include
     an untrue statement of a material fact or omits or will omit to state any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading and (C) neither the Prospectus nor any
     amendment or supplement thereto includes or will include an untrue
     statement of a material fact or omit to state a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading; provided, however, that this
                                                 --------  -------           
     representation and warranty does not apply to statements or omissions made
     in reliance upon and in conformity with information furnished in writing by
     you to the Company expressly for use in the Registration Statement or the
     Prospectus.  At the Closing Time, the Designated Indenture (as defined
     below) will comply in all material respects with the requirements of the
     1939 Act and the 1939 Act Regulations.
<PAGE>
 
                                       3

          (ii) The documents incorporated by reference in the Prospectus
     pursuant to Item 12 of Form S-3 under the 1933 Act, at the time they were
     filed with the Commission, complied in all material respects with the
     requirements of the 1934 Act, and the rules and regulations of the
     Commission thereunder (the "1934 Act Regulations"), and, when read together
     and with the other information in the Prospectus, do not and will not, on
     the date hereof and at all times subsequent thereto up to the Closing Time,
     include an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading.

          (iii)  KPMG Peat Marwick LLP, who are reporting upon the audited
     financial statements and schedules included or incorporated by reference in
     the Registration Statement, are independent accountants as required by the
     1933 Act and the 1933 Act Regulations.

          (iv) This Agreement has been duly authorized, executed and delivered
     by the Company.

          (v) The consolidated historical financial statements included or
     incorporated by reference in the Registration Statement present fairly the
     consolidated financial position of the Company and its subsidiaries as of
     the dates indicated and the consolidated results of operations and changes
     in financial position of the Company and its subsidiaries for the periods
     specified.  Such financial statements have been prepared in conformity with
     generally accepted accounting principles applied on a consistent basis
     throughout the periods involved.  The financial statement schedules, if
     any, included in the Registration Statement present fairly the information
     required to be stated therein.  The selected financial data included in the
     Prospectus present fairly the information shown therein and have been
     compiled on a basis consistent with that of the audited consolidated
     financial statements included or incorporated by reference in the
     Registration Statement.  The pro forma financial statements and other pro
     forma financial information included in the Prospectus present fairly the
     information shown therein, have been prepared in accordance with the
     Commission's rules and guidelines with respect to pro forma financial
     statements, have been properly compiled on the pro forma bases described
     therein, and, in the opinion of the Company, the assumptions used in the
     preparation thereof are reasonable and the adjustments used therein are
     appropriate to give effect to the transactions or circumstances referred to
     therein.

          (vi) The Company is a corporation duly organized, validly existing and
     in good standing under the laws of the State of Delaware with power and
     authority (corporate and other) under such laws to own, lease and operate
     its properties and
<PAGE>
 
                                       4

     conduct its business as described in the Prospectus; and the Company is
     duly qualified to transact business as a foreign corporation and is in good
     standing in each other jurisdiction in which it owns or leases property of
     a nature, or transacts business of a type, that would make such
     qualification necessary, except to the extent that the failure to so
     qualify or be in good standing would not have a material adverse effect on
     the Company and its subsidiaries, considered as one enterprise.

          (vii)  The subsidiaries of the Company set forth on Schedule V are, as
     of the date hereof, all of the "Restricted Subsidiaries", as such term is
     defined under each of  (a) the indenture, dated as of April 1, 1992, for
     the Company's 10-3/4% Senior Subordinated Debentures due 2004, (b) the
     indenture, dated as of February 15, 1993, for the Company's 9-7/8% Senior
     Subordinated Debentures due 2013 and (c) the indenture, dated as of April
     1, 1993, for the Company's 9-7/8% Senior Subordinated Debentures due 2023;
     and the Bank Credit Agreement (as such term is defined in the Designated
     Indenture).  The subsidiaries of the Company set forth on Schedule VI are
     Unrestricted Subsidiaries (the Restricted Subsidiaries and the Unrestricted
     Subsidiaries are hereinafter referred to collectively as the
     "Subsidiaries").  The Subsidiaries on Schedules V and VI with an asterisk
     by their names are the only subsidiaries of the Company which had at
     December 31, 1994 assets in excess of 10% of the consolidated assets of the
     Company and its subsidiaries as at that date or had, in the aggregate, for
     the fiscal year then ended revenues or operating cash flow in excess of 10%
     of consolidated revenues or consolidated operating cash flow of the Company
     and its subsidiaries for such period (such Subsidiaries are referred to
     herein as the "Material Subsidiaries").  In making this determination, any
     subsidiary acquired after December 31, 1994 shall be deemed to have been
     acquired as of such date.

          (viii)  Each Material Subsidiary that is a corporation is duly
     organized, validly existing and in good standing under the laws of the
     jurisdiction of its incorporation with power and authority (corporate and
     other) under such laws to own, lease and operate its properties and conduct
     its business; and each such Material Subsidiary is duly qualified to
     transact business as a foreign corporation and is in good standing in each
     other jurisdiction in which it owns or leases property of a nature, or
     transacts business of a type, that would make such qualification necessary,
     except to the extent that the failure to so qualify or be in good standing
     would not have a material adverse effect on the Company and its
     subsidiaries, considered as one enterprise.  All of the outstanding shares
     of capital stock of each Material Subsidiary have been duly authorized and
     validly issued and are fully paid and non-assessable and, except as
     disclosed on Schedule V or VI to this Agreement or as disclosed or
     contemplated by the Prospectus, are owned by the Company, directly or
     through one or more subsidiaries, free and clear of any pledge, lien,
     security interest, charge, claim, equity or encumbrance of any kind.
<PAGE>
 
                                       5

          (ix) Each of the Material Subsidiaries in which the Company or a
     subsidiary of the Company is a limited or general partner (hereinafter
     called the "Partnerships") has been duly formed and is validly existing as
     a limited or general partnership, as the case may be, under the laws of its
     jurisdiction of organization, with full power and authority to own, lease
     and operate properties and conduct its business; all necessary filings with
     respect to the formation of the Partnerships as limited or general
     partnerships (as the case may be) have been made under such laws; and each
     of the Partnerships is duly qualified to transact business and is in good
     standing in each other jurisdiction in which it owns or leases property of
     a nature, or transacts business of a type, that would make such
     qualification necessary, except to the extent that the failure to so
     qualify or be in good standing would not have a material adverse effect on
     the Company and its subsidiaries, considered as one enterprise.

          (x) All of the outstanding shares of capital stock of the Company have
     been duly authorized and validly issued and are fully paid and non-
     assessable; none of the outstanding shares of capital stock of the Company
     was issued in violation of the preemptive rights of any stockholder of the
     Company.

          (xi) The Subordinated Indenture, as supplemented to the date hereof
     (the Subordinated Indenture, as so supplemented, the "Designated
     Indenture"), has been duly authorized by the Company.  The Subordinated
     Indenture as executed is or will be substantially in the form filed as an
     exhibit to the Registration Statement.  The Designated Indenture, when duly
     executed and delivered (to the extent required by the Subordinated
     Indenture) by the Company and the Subordinated Trustee, will constitute a
     valid and binding obligation of the Company, enforceable against the
     Company in accordance with its terms, subject to bankruptcy, insolvency,
     fraudulent transfer, reorganization, moratorium and similar laws of general
     applicability relating to or affecting creditors' rights and general
     principles of equity (regardless of whether enforcement is considered in a
     proceeding in equity or at law); and the form of Designated Indenture
     conforms in all material respects to the description thereof contained in
     the Prospectus.

          (xii)  The Offered Securities have been duly authorized by the
     Company.  When executed, authenticated, issued and delivered in the manner
     provided for in the Designated Indenture and sold and paid for as provided
     herein and in any Delayed Delivery Contracts (as defined below), the
     Offered Securities will constitute valid and binding obligations of the
     Company entitled to the benefits of the Designated Indenture and
     enforceable against the Company in accordance with their terms, subject to
     bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
     similar laws of general applicability relating to or affecting creditors'
     rights and general principles of equity (regardless of whether enforcement
     is considered in a
<PAGE>
 
                                       6

     proceeding in equity or at law); and the form of Offered Securities
     conforms in all material respects to the description thereof contained in
     the Prospectus.

          (xiii)  In the event that any of the Offered Securities are purchased
     pursuant to Delayed Delivery Contracts, each of such Delayed Delivery
     Contracts has been duly authorized by the Company and, when executed and
     delivered on behalf of the Company and duly authorized, executed and
     delivered on behalf of the purchaser thereunder, will constitute a valid
     and binding obligation of the Company enforceable against the Company in
     accordance with its terms, subject to bankruptcy, insolvency, fraudulent
     transfer, reorganization, moratorium and similar laws of general
     applicability relating to or affecting creditors' rights and general
     principles of equity (regardless of whether enforcement is considered in a
     proceeding in equity or at law).

          (xiv)  Since the respective dates as of which information is given in
     the Registration Statement and the Prospectus, except as otherwise stated
     therein or contemplated thereby, there has not been (A) any material loss
     or interference with its business from fire, explosion, flood or other
     calamity, whether or not covered by insurance, or from any labor dispute or
     court or governmental action, order or decree and there has not been any
     change in the capital stock or long term debt of the Company or any of its
     Subsidiaries or any change which the Company has reasonable cause to
     believe will involve any material adverse change, or any development
     involving a prospective material adverse change, in or affecting the
     financial position, stockholders' equity or results of operations of the
     Company and its subsidiaries, considered as one enterprise, or (B) any
     transaction entered into by the Company or any subsidiary, other than in
     the ordinary course of business, that is material to the Company and its
     subsidiaries, considered as one enterprise, or (C) any dividend or
     distribution of any kind declared, paid or made by the Company on its
     capital stock.

          (xv) Neither the Company nor any Subsidiary is in default in the
     performance or observance of any obligation, agreement, covenant or
     condition contained in any contract, indenture, mortgage, loan agreement,
     note, lease or other agreement or instrument to which it is a party or by
     which it may be bound or to which any of its properties may be subject,
     except for such defaults that would not have a material adverse effect on
     the financial position, stockholders' equity or results of operations of
     the Company and its subsidiaries, considered as one enterprise.  The
     execution and delivery by the Company of this Agreement, the Designated
     Indenture and any Delayed Delivery Contracts (the "Operative Documents"),
     the issuance and delivery of the Offered Securities, the consummation by
     the Company of the transactions contemplated by this Agreement and the
     compliance by the Company with the terms of the Operative Documents, have
     been duly authorized by all necessary corporate action on the part of the
     Company and do not and will not result in any violation of the charter or
     by-laws of the Company or any Subsidiary, and do
<PAGE>
 
                                       7

     not and will not conflict with, or result in a breach of any of the terms
     or provisions of, or constitute a default under, or result in the creation
     or imposition of any lien, charge or encumbrance upon any property or
     assets of the Company or any Subsidiary under (A) any contract, indenture,
     mortgage, loan agreement, note, lease or other agreement or instrument to
     which the Company or any Subsidiary is a party or by which it may be bound
     or to which any of its properties may be subject (except for such
     conflicts, breaches or defaults or liens, charges or encumbrances that
     would not have a material adverse effect on the financial position,
     stockholders' equity or results of operations of the Company and its
     subsidiaries, considered as one enterprise), or (B) any existing applicable
     law, rule, regulation, judgment, order or decree of any government,
     governmental instrumentality or court, domestic or foreign, having
     jurisdiction over the Company or any Subsidiary or any of its properties
     (except for such conflicts, breaches or defaults or liens, charges or
     encumbrances that would not have a material adverse effect on the financial
     position, stockholders' equity or results of operations of the Company and
     its subsidiaries, considered as one enterprise), or (C) any material
     agreement or other material instrument (including any franchise agreement,
     license, permit or other governmental authorization granted by the Federal
     Communications Commission (hereinafter called the "FCC"), The New York
     State Commission on Cable Television, the Massachusetts Cable Television
     Commission or any other governing body having jurisdiction over cable
     television operations) binding upon the Company or any of its Subsidiaries
     (except for such conflicts, breaches or defaults or liens, charges or
     encumbrances that would not have a material adverse effect on the financial
     position, stockholders' equity or results of operations of the Company and
     its subsidiaries, considered as one enterprise).

     "Description of Debt Securities", "Description of the Notes" and "Recent
     Developments- Impact of Pending Telecommunications Legislation on FCC Cable
     Rate Regulation" and the statements in the Company's annual report on Form
     10-K for the year ended December 31, 1994 (the "1994 Form 10-K"), which is
     incorporated by reference in the Prospectus, under "Business - Cable
     Television Operations - Competition" and "Business - Cable Television
     Operations - Regulation" and in the Registration Statement in Item 15, and
     the statements cross referenced therein, insofar as such statements

     proceedings, do not contain any untrue statement of a material fact or omit
     to state a material fact required to be stated therein or necessary in

          (xvii)  Except as disclosed in the Prospectus, no authorization,
     approval, consent or license of any government, governmental
     instrumentality or court,

     valid authorization, issuance, sale and delivery of the Offered Securities
     in the United States, or for the execution, delivery or performance of the
     Designated Indenture and this Agreement by the Company except for any such
     consent, approval, authorization, order or registration the failure of
     which to obtain or make or the absence of which would result in no material
     adverse effect on the Company and its subsidiaries, considered as one
     enterprise.

          (xviii)  Except as disclosed in the Prospectus, there is no action,
     suit or proceeding before or by any government, governmental
     instrumentality or court, domestic or foreign, now pending or, to the best
     of the Company's knowledge, threatened against or affecting the Company or

     the Company has reasonable cause to believe will result in any material
     adverse change in the consolidated financial position, stockholders' equity
     or results of operations of the Company and its subsidiaries, considered as
     one enterprise or will materially and adversely affect the properties or
     assets of the Company and its subsidiaries, considered as one enterprise,
     or that the Company has reasonable cause to believe will materially
     adversely affect the consummation of the transactions contemplated in this
     Agreement.

          (xix)  There are no contracts or documents of a character required to
     be described in the Registration Statement or the Prospectus or to be filed
     as exhibits to the Registration Statement that are not described and filed

          (xx) The Company and the Subsidiaries each has good and marketable
     title to all material properties and assets described in the Prospectus as

     are neither material in amount nor materially significant in relation to
     the business of the Company and its subsidiaries, considered as one
     enterprise; and any material real property and buildings under lease by the
     Company and the Subsidiaries are held by them under valid, subsisting and
     enforceable leases with such exceptions as do not interfere, to an extent
     material to the Company and its subsidiaries, considered as one enterprise,
     with the use made and proposed to be made of such property and buildings by
     the Company and the Subsidiaries.

          (xxi)  Except as disclosed in the Prospectus, the Company and the
     Subsidiaries each owns, possesses or has obtained all material agreements,

     as the case may be, and to operate its properties and to carry on its
     business as presently conducted, and neither the Company nor any Subsidiary
     has received any notice of proceedings relating to revocation or
     modification of any such licenses, permits, certificates, consents, orders,
     approvals or authorizations.

          (xxii)  To the best knowledge of the Company, and except as disclosed
     in the Prospectus, no labor problem exists with its employees or with
     employees of the Subsidiaries that could reasonably be expected to
     materially and adversely affect the financial position, stockholders'
     equity or results of operations of the Company and its subsidiaries,
     considered as one enterprise.

          (b) Any certificate signed by any officer of the Company or any
Subsidiary and delivered to you or to counsel for the Underwriters in connection
with the offering of the Offered Securities shall be deemed a representation and
warranty by the Company to each Underwriter as to the matters covered thereby.

          Section 2.  Sale and Delivery to the Underwriters; Closing.  (a)  On
                      ----------------------------------------------          
the basis of the representations and warranties herein contained, and subject to
the terms and conditions herein set forth, the Company agrees to sell to each
Underwriter, and each Underwriter agrees, severally and not jointly, to purchase
from the Company, at the purchase price to the Underwriters set forth in
Schedule II, the principal amount of Offered Securities set forth opposite the
name of such Underwriter in Schedule I.

          (b) Payment of the purchase price for, and delivery of, the Offered
Securities shall be made at the offices of Shearman & Sterling, 599 Lexington
Avenue, New York, New York 10022, or at such other place in the City of New
York, at 10:00 A.M. as shall be agreed upon by the Company and you, or as shall
otherwise be provided in Section 10 (such date and time of payment and delivery
being herein called the "Closing Time").  Payment shall be made to the Company
in the manner specified in Schedule II hereto, against delivery of the Offered
Securities to you for the respective accounts of the several Underwriters.
Except as otherwise provided in Schedule II hereto, such Offered Securities
shall be in such denominations ($1,000 or an integral multiple thereof) and
registered in such names as you may request in writing at least two full
business days before the Closing Time.  Such Offered Securities will be made
available in New York City for examination and packaging by you not later than
10:00 A.M. on the business day prior to the Closing Time.

          (c) If specified in Schedule II, the Underwriters may solicit offers
to purchase Offered Securities from the Company pursuant to delayed delivery
contracts ("Delayed Delivery Contracts") substantially in the form of Schedule
IV with such changes therein as the Company may approve.  Any Delayed Delivery
Contracts are to be with
<PAGE>
 
                                       10

institutional investors of the types set forth in the Prospectus.  At the
Closing Time, the Company will enter into Delayed Delivery Contracts (for the
minimum principal amount of Offered Securities per Delayed Delivery Contract
specified in Schedule II) with all purchasers proposed by the Underwriters and
previously approved by the Company as provided below, but not for an aggregate
principal amount of Offered Securities less than or greater than the minimum and
maximum aggregate principal amounts specified in Schedule II.  The Underwriters
will not have any responsibility for the validity or performance of Delayed
Delivery Contracts.

          (d) You are to submit to the Company, at least three business days
prior to the Closing Time, the names of any institutional investors with which
it is proposed that the Company enter into Delayed Delivery Contracts, the
principal amount of Offered Securities to be purchased by each of them and the
date of delivery thereof, and the Company will advise you, at least two business
days prior to the Closing Time, of the names of the institutions with which the
making of Delayed Delivery Contracts is approved by the Company and the
principal amount of Offered Securities to be covered by each such Delayed
Delivery Contract.

          (e) As compensation for arranging Delayed Delivery Contracts, the
Company will pay (by certified or official bank check in New York Clearing House
or similar next day funds) to you at the time of the closing, for the accounts
of the Underwriters, a fee equal to that percentage of the principal amount of
Offered Securities for which Delayed Delivery Contracts are made at the Closing
Time as is specified in Schedule II or the amount of such fee may be deducted
from the check delivered pursuant to Section 2(b).

          (f) The principal amount of Offered Securities agreed to be purchased
by each Underwriter shall be reduced by the principal amount of Offered
Securities covered by Delayed Delivery Contracts, as to such Underwriter as set
forth in a notice delivered by you to the Company; provided, however, that the
                                                   --------  -------          
total principal amount of Offered Securities to be purchased by all Underwriters
shall be the principal amount of Offered Securities covered by this Agreement,
less the principal amount of Offered Securities covered by all Delayed Delivery
Contracts.

          Section 3.  Certain Covenants of the Company.  The Company covenants
                      --------------------------------

     agreed to purchase, the name of each Underwriter, if any, acting as
     representative of the Underwriters in connection with the offering, the
     price at which the Offered Securities are to be purchased by the
     Underwriters from the Company, any initial public offering price, any
     selling concession and reallowance and any delayed delivery arrangements,

     filing pursuant to Rule 424 under the 1933 Act and will furnish to the
     Underwriters as many copies of any preliminary prospectus supplement and
     the Prospectus as you shall reasonably request.

     Company will, subject to Section 3(c), file promptly all documents required
     to be filed with the Commission pursuant to Section 13 or 14 of the 1934
     Act subsequent to the time the Registration Statement becomes effective.

          (c) During the period when the Prospectus is required by the 1933 Act
     to be delivered in connection with sales of the Offered Securities, the
     Company will inform you of its intention to file any amendment to the
     Registration Statement, any supplement to the Prospectus or any document
     that would as a result thereof be incorporated by reference in the
     Prospectus; will furnish you with copies of any such amendment, supplement
     or other document a reasonable time in advance of filing; and will not file
     any such amendment, supplement or other document in a form to which you
     shall reasonably object.

          (d) During the period when the Prospectus is required by the 1933 Act
     to be delivered in connection with sales of the Offered Securities, the
     Company will notify you immediately, and confirm the notice in writing
     (with respect to clause (i), upon request), (i) of the effectiveness of any
     amendment to the Registration Statement, (ii) of the receipt of any
     comments from the Commission with respect to the Registration Statement,
     the Prospectus or the Prospectus Supplement, (iii) of any request by the
     Commission to amend the Registration Statement or any supplement to the
     Prospectus or for additional information relating thereto and (iv) of the
     issuance by the Commission of any stop order suspending the effectiveness
     of the Registration Statement, of the suspension of the qualification of
     the Offered Securities for offering or sale in any jurisdiction, or of the
     institution or to the Company's knowledge, the threatening of any
     proceedings for any of such purposes.  The Company will use every
     reasonable effort to prevent the issuance of any such stop order or of any
     order preventing or suspending such use and, if any such order is issued,
     to obtain the lifting thereof at the earliest possible moment.

     effect for a period of not less than one year from the date hereof;

     general consent to service of process or to qualify as a foreign
     corporation or as a dealer in securities in any jurisdiction in which it is
     not so qualified or to subject itself to taxation in respect of doing

     period covered thereby (90 calendar days in the case the period corresponds
     to the fiscal year of the Company), an earnings statement of the Company
     (in form complying with the provisions of Rule 158 of the 1933 Act
     Regulations), covering a period of 12 months beginning after the effective

     beginning after the effective date of any post-effective amendment to the
     Registration Statement but not later than the first day of the Company's
     fiscal quarter next following such effective date.

     Act and the 1933 Act Regulations, the 1934 Act and the 1934 Act Regulations
     and the 1939 Act and the 1939 Act Regulations.  If at any time when the

     is necessary to amend the Registration Statement or amend or supplement the
     Prospectus in order that the Prospectus will not include an untrue
     statement of a material fact or omit to state a material fact necessary in
     order to make the statements therein not misleading in the light of the
     circumstances existing at the time it is delivered to a purchaser, or if it
     shall be necessary at any such time to amend the Registration Statement or
     amend or supplement the Prospectus in order to comply with the requirements
     of the 1933 Act or the 1933 Act Regulations, the Company will promptly
     prepare and file with the Commission, subject to Section 3(c), such
     amendment or supplement as may be necessary to correct such untrue
     statement or omission or to make the Registration Statement or the
     Prospectus comply with such requirements.

          (i) The Company will use the net proceeds received by it from the sale

     of 1940, as amended (the "Investment Company Act").

     or, to the knowledge of the Company, shall be contemplated by the

          (b) At the Closing Time, you shall have received a signed opinion of
     Sullivan & Cromwell, counsel for the Company, dated as of the Closing Time,
     in form and substance satisfactory to counsel for the Underwriters, to the
     effect that:
 
               (i) The Company has been duly incorporated and is an existing
          corporation in good standing under the laws of the State of Delaware.

               (ii) The Designated Indenture has been duly authorized, executed
          and delivered by the Company and duly qualified under the 1939 Act;
          the Offered Securities have been duly authorized, executed,
          authenticated, issued and delivered; and the Designated Indenture and
          the Offered Securities constitute valid and legally binding
          obligations of the Company enforceable in accordance with their terms
          or, in the case of Offered Securities, if any, to be delivered
          pursuant to Delayed Delivery Contracts, when duly executed and
          authenticated as provided in the Designated Indenture and issued,
          delivered and paid for in accordance with such Delayed Delivery
          Contracts, will constitute, valid and binding obligations of the

          terms, subject to bankruptcy, insolvency, fraudulent transfer,
          reorganization, moratorium and similar laws of

          general applicability relating to or affecting creditors' rights and
          to general equity principles.

               (iii)  The execution and delivery of this Agreement and the
          Designated Indenture by the Company, the issuance and delivery by the
          Company of the Offered Securities to the Underwriters and compliance
          by the Company with the terms of this Agreement and the Designated
          Indenture do not and will not result in any violation of the
          Certificate of Incorporation or By-laws of the Company; and all
          regulatory consents, authorizations, approvals and filings required to
          be obtained or made by the Company under the Federal laws of the
          United States, the laws of the State of New York and the General
          Corporation Law of the State of Delaware for the issuance, sale and

          Delivery Contract that has been executed by the Company has been duly
          authorized, executed and delivered by the Company and, assuming the
          due authorization, execution and delivery by the purchaser thereunder,
          is a valid and binding obligation of the Company enforceable against
          the Company in accordance with its terms, subject to bankruptcy,
          insolvency, fraudulent transfer, reorganization, moratorium and
          similar laws of general applicability relating to or affecting

               (v) This Agreement has been duly authorized, executed and
          delivered by the Company.

               Such counsel shall also furnish you with a letter to the effect
     that as counsel to the Company, they reviewed the Registration Statement
     and the Prospectus, participated in discussions with representatives of the
     Underwriters and of the Company and its accountants and advised the Company
     as to the requirements of the 1933 Act and the applicable rules and
     regulations thereunder; between the date of the Prospectus Supplement and
     the Closing Time, such counsel participated in further discussions with
     representatives of the Underwriters and of the Company and its accountants
     in which the contents of certain portions of the Prospectus and related
     matters were discussed and reviewed certain documents filed by the Company
     with the Commission, certificates of certain officers of the Company, an
     opinion addressed to the Underwriters from Robert S. Lemle, Esq. and a
     letter from the Company's independent accountants; on the basis of the
     information that such counsel gained in the course of the performance of
     the services referred to above, considered in the light of such counsel's
     understanding of the applicable law (including the requirements
<PAGE>
 
                                       16

     of Form S-3 and the character of the prospectus contemplated thereby) and
     the experience such counsel have gained through their practice under the
     1933 Act, they confirm to you that, in such counsel's opinion, the
     Registration Statement and the Prospectus, and each amendment or supplement
     thereto, as of their respective effective or issue dates appeared on their
     face to be appropriately responsive in all material respects to the
     requirements of the 1933 Act, the 1939 Act, and the applicable rules and
     regulations of the Commission thereunder; further, nothing that came to
     such counsel's attention in the course of such review has caused such
     counsel to believe that any part of the Registration Statement, when such
     part became effective, contained any untrue statement of a material fact or
     omitted to state any material fact required to be stated therein or
     necessary to make the statements therein not misleading or that the
     Prospectus as of the date of the Prospectus Supplement contained any untrue
     statement of a material fact or omitted to state any material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; also, nothing
     that came to the attention of such counsel in the course of the procedures
     described in the second clause of this paragraph has caused such counsel to
     believe that the Prospectus, as supplemented by the Prospectus Supplement,
     as of the Closing Time, contained any untrue statement of a material fact
     or omitted to state any material fact necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading; such counsel shall state that the limitations
     inherent in the independent verification of factual matters and the
     character of determinations involved in the registration process are such
     that such counsel does not assume any responsibility for the accuracy,
     completeness or fairness of the statements contained in the Registration
     Statement or the Prospectus except for those made under the captions
     "Description of Debt Securities", "Description of the Notes" and
     "Underwriting" in the Prospectus insofar as they relate to provisions of
     documents therein described; also, such counsel need express no opinion or
     belief as to the financial statements or other financial data contained in
     the Registration Statement or the Prospectus, or as to the description of
     statutes, regulations, proceedings or matters referred to in Section 5(d)
     hereof or as to the statement of eligibility of the Subordinated Trustee
     under the Designated Indenture under which the Offered Securities are being
     issued.

               In rendering such opinion, such counsel may state that they
     express no opinion as to the laws of any jurisdiction other than the
     Federal laws of the United States, the laws of the State of New York and
     the General Corporation Law of the State of Delaware and no opinion as to
     federal or communications laws.  Such counsel may also state that, insofar
     as such opinion involves factual matters, they have relied, to the extent
     they deem proper, upon certificates of officers of the Company and the
     Subsidiaries and certificates of public officials.

     the Underwriters, to the effect that:

               (i) The Company is a corporation duly organized, validly existing

          Prospectus.

               (ii) The Company is duly qualified to transact business as a
          foreign corporation and is in good standing in each other jurisdiction
          in which it owns or leases property of a nature, or transacts business
          of a type, that would make such qualification necessary, except where
          the failure to be so qualified would not have a material adverse
          effect on the Company and its subsidiaries, considered as one
          enterprise.

               (iii)   Each Material Subsidiary that is a corporation is duly
          incorporated, validly existing and in good standing under the laws of
          the jurisdiction of its incorporation, with corporate power and
          authority under such laws to own, lease and operate its properties and
          conduct its business.  Each Material Subsidiary that is a partnership
          is duly organized under the laws of the jurisdiction of its
          organization.

               (iv) All of the outstanding shares of capital stock of each
          Material Subsidiary have been duly authorized and validly issued and
          are fully paid and nonassessable; except as set forth on Schedules V
          and VI to this Agreement or as disclosed in or as contemplated by the
          Prospectus, all of such shares are owned by the Company, directly or
          through one or more subsidiaries, free and clear of any material
          pledge, lien, security interest, charge, claim, equity or encumbrance
          of any kind; no holder thereof is subject to personal liability under
          the certificate of incorporation or by-laws of the respective Material
          Subsidiary or the corporation law of the jurisdiction in which such
          Material Subsidiary is organized by reason of being such a holder and
          none of such shares was issued in violation of the preemptive rights
          of any stockholder of such Material Subsidiary under the certificate
          of incorporation or by-laws of such Material Subsidiary or the
          corporation law of the jurisdiction in which such Material Subsidiary
          is organized.

               (v) To such counsel's knowledge, there are no legal or
          governmental proceedings pending or threatened to which the Company or
          any of its subsidiaries is or may be a party, or of which any of their
          properties are
<PAGE>
 
                                       18

          or may be the subject, of a character which are required to be
          disclosed in the Registration Statement, the Prospectus, the annual
          Form 10-K or any Form 10-Q of the Company, other than those disclosed
          therein.

               (vi) The documents incorporated by reference in the Prospectus or
          any further amendment or supplement thereto made by the Company prior
          to the Closing Time (other than the financial statements and related
          schedules therein and any untrue statement or omission of a material
          fact contained therein which was corrected in the Prospectus, as to
          which such counsel need express no opinion), when they became
          effective or were filed with the Commission, as the case may be,
          complied as to form in all material respects with the requirements of
          the Exchange Act and the rules and regulations of the Commission
          thereunder; and he has no reason to believe that such documents
          considered together contained, as of the date of the Prospectus
          Supplement or as of the Closing Time, an untrue statement of a
          material fact, or omitted to state a material fact necessary in order
          to make the statements therein, in the light of the circumstances
          under which they were made, not misleading.

               (vii)  Such counsel does not know of any contracts or documents
          of a character required to be described or referred to in the
          Registration Statement or the Prospectus or to be filed as exhibits to
          the Registration Statement that are not described, referred to or
          filed as required.

               (viii)   To the knowledge of such counsel, no default exists in
          the performance or observance of any material obligation, agreement,
          covenant or condition contained in any contract, indenture, loan
          agreement, note, lease or other agreement or instrument that is
          described or referred to in the Registration Statement or the
          Prospectus or filed as an exhibit to the Registration Statement or any
          subsequent Form 10-Q of the Company, which default would have a
          material adverse effect on the financial position, stockholders'
          equity or results of operations of the Company and its subsidiaries,
          considered as one enterprise.

               (ix) The execution and delivery of the Operative Documents by the
          Company, the issuance and delivery of the Offered Securities, the
          consummation by the Company of the transactions contemplated in this
          Agreement and compliance by the Company with the terms of this
          Agreement and the Designated Indenture will not conflict with the
          terms or provisions of, or constitute a default under, any indenture,
          mortgage, deed of trust, loan agreement or other agreement or
          instrument (including any franchise agreement, license, permit or
          other governmental authorization granted by the FCC, The State of New
          York Commission on Cable Television, or any other
<PAGE>
 
                                       19

          Federal or New York State governing body having jurisdiction over
          cable television operations) known to such counsel to which the
          Company or any Subsidiary is a party or by which the Company or any
          Subsidiary is bound or to which any of the property or assets of the
          Company or any Subsidiary is subject, which conflict, breach,
          violation or default would have a material adverse effect on the
          financial position, stockholders' equity or results of operations of
          the Company and its subsidiaries, taken as a whole, nor will such
          action result in any violation of the provisions of the Certificate of
          Incorporation or By-laws of the Company or any Federal, New York or
          Delaware General Corporation Law statute or any order, rule or
          regulation known to such counsel of any Federal, New York or Delaware
          court or governmental agency or body having jurisdiction over the
          Company or any Subsidiary or any of their properties, which violation
          in each case would have a material adverse effect on the financial
          position, stockholders' equity or results of operations of the Company
          and its subsidiaries, taken as a whole; and no consent, approval,
          authorization, order, registration or qualification of or with any
          such court or governmental agency or body is required for the issue
          and sale of the Offered Securities or the consummation by the Company
          of the transactions contemplated by this Agreement, except with
          respect to such consents, approvals, authorizations, registrations or
          qualifications as may be required under state or foreign securities
          laws in connection with the purchase and distribution of the Offered
          Securities by the Underwriters.

          In rendering such opinion, such counsel may state that he expresses no
opinion as to the laws of any jurisdiction other than the Federal laws of the
United States (other than federal communications laws, as to which such counsel
need express no opinion), the laws of the State of New York and the General
Corporation Law of the State of Delaware.  In giving such opinion, such counsel
may rely, as to all matters governed by the laws of any other jurisdiction, upon
opinions of other counsel, who shall be counsel satisfactory to counsel for the
Underwriters, in which case the opinion shall state that he believes you and he
are entitled to so rely.  Such counsel may also state that, insofar as such
opinion involves factual matters, he has relied, to the extent he deems proper,
upon certificates of officers of the Company and the Subsidiaries and
certificates of public officials.

          (d) At the Closing Time you shall have received a signed opinion of
     Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., as special federal
     communications counsel to the Company, in form and substance satisfactory
     to counsel to the Underwriters, to the effect that:

               (i) The approvals, if any, required to be obtained from the FCC
          to consummate the transactions contemplated by this Agreement have
          been obtained and are in full force and effect.
<PAGE>
 
                                       20

              (ii) Such counsel does not know of any federal communications and
          copyright statutes that are principally directed to the regulation of
          cable properties applicable to the Company that are not described in
          the Prospectus but would be material and relevant to the business of
          the Company, and the descriptions in the Prospectus of such statutes
          therein described are accurate and fairly summarize such statutes.

               (iii)  The information in the Registration Statement and
          Prospectus under the captions "Risk Factors -- Risk Related to Cable
          Regulation", "Risk Factors -- Risk of Competition", and "Risk Factors
          --  Competition from Telephone Companies" and in the 1994 Form 10-K
          under the captions "Business -- Cable Television Operations --
          Regulation" to the extent that such sections describe statutes,
          regulations and governmental proceedings or matters involving federal
          communications and copyright law and policy and the impact thereof on
          the business in which the Company and its subsidiaries are engaged,
          has been reviewed by them and fairly represents the communications and
          copyright law described therein applicable to the Company and its
          subsidiaries as disclosed in the Prospectus and material and relevant
          to the business of the Company and its subsidiaries.

     In giving such opinion, such counsel may rely, as to all matters governed
     by the laws of jurisdictions other than the law of the District of
     Columbia, the federal law of the United States and the corporate law of the
     State of Delaware, upon opinions of other counsel, who shall be counsel
     satisfactory to counsel for the Underwriter, in which case the opinion
     shall state that they believe you and they are entitled to so rely.  Such
     counsel may also state that, insofar as such opinion involves factual
     matters, they have relied, to the extent they deem proper, upon
     certificates of officers of the Company and the Subsidiaries and
     certificates of public officials.  Such counsel may strictly confine such
     opinion to matters involving the Federal Communications Act of 1934, as
     amended (the "Communications Act"), the rules and regulations of the FCC,
     and those provisions of the federal copyright law that are principally
     directed to the regulation of the cable properties.  Such counsel may also
     limit such opinion to the state of the law as it exists under the
     Communications Act, the rules and regulations of the FCC, and federal
     copyright law as of the date thereof.

          (e) At the Closing Time, you shall have received the favorable opinion
     of Shearman & Sterling, counsel for the Underwriters, dated as of the
     Closing Time, to the effect that the opinions delivered pursuant to
     Sections 5(b), 5(c), and 5(d) appear on their face to be appropriately
     responsive to the requirements of this Agreement except, specifying the
     same, to the extent waived by you, and with respect to the incorporation
     and legal existence of the Company, the Offered Securities, this Agreement,
     the Designated Indenture, the Registration Statement, the Prospectus, the
<PAGE>
 
                                       21

     documents incorporated by reference and such other related matters as you
     may require.  In rendering such opinion, such counsel may state that they
     express no opinion as to the laws of any jurisdiction other than the
     Federal laws of the United States, the laws of the State of New York and
     the General Corporation Law of the State of Delaware, and no opinion as to
     federal or state communications laws.  Such counsel may also state that,
     insofar as such opinion involves factual matters, they have relied, to the
     extent they deem proper, upon certificates of officers of the Company and
     the Subsidiaries and certificates of public officials.

          (f) At the Closing Time, (i) the Registration Statement and the
     Prospectus, as they may then be amended or supplemented, shall contain all
     statements that are required to be stated therein under the 1933 Act and
     the 1933 Act Regulations and in all material respects shall conform to the
     requirements of the 1933 Act and the 1933 Act Regulations and the 1939 Act
     and the 1939 Act Regulations, and neither the Registration Statement nor
     the Prospectus, as they may then be amended or supplemented, shall contain
     an untrue statement of a material fact or omit to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, (ii) there shall not have been, since the respective dates
     as of which information is given in the Registration Statement, any
     material adverse change or any development involving a prospective material
     adverse change in or affecting the financial position, stockholders' equity
     or results of operations of the Company and its subsidiaries, considered as
     one enterprise, (iii) the Company shall have complied with all agreements
     and satisfied all conditions on its part to be performed or satisfied at or
     prior to the Closing Time and (iv) the other representations and warranties
     of the Company set forth in Section 1(a) shall be accurate as though
     expressly made at and as of the Closing Time. At the Closing Time, you
     shall have received a certificate of the President, a Vice Chairman or a
     Vice President, and the Treasurer or Controller, of the Company, dated as
     of the Closing Time, to such effect.

          (g) You shall have received the letter or letters specified in
     Sections 1 and 2 of Schedule III at the date hereof and the letter
     specified in Section 3 of Schedule III at the Closing Time, as well as a
     letter from Deloitte & Touche LLP dated as of the date hereof substantially
     in the form annexed to Schedule III.

          (h) Unless otherwise specified in Schedule II hereto, on or after the
     date hereof (i) no downgrading shall have occurred in the rating accorded
     the Company's debt securities by any "nationally recognized statistical
     rating organization," as that term is defined by the Commission for
     purposes of Rule 436(g)(2) under the 1933 Act and (ii) no such organization
     shall have publicly announced that it has under surveillance or review,
     with possible negative implications, its rating of any of the Company's
     debt securities.
<PAGE>
 
                                       22

          (i) At the Closing Time, counsel for the Underwriters shall have been
     furnished with all such documents, certificates and opinions as they may
     reasonably request for the purpose of enabling them to pass upon the
     issuance and sale of the Offered Securities as herein contemplated and the
     matters referred to in Section 5(e) and in order to evidence the accuracy
     and completeness of any of the representations, warranties or statements of
     the Company, the performance of any of the covenants of the Company, or the
     fulfillment of any of the conditions herein contained.

          If any of the conditions specified in this Section 5 shall not have
been fulfilled when and as required by this Agreement to be fulfilled, this
Agreement may be terminated by you on notice to the Company at any time at or
prior to the Closing Time, and such termination shall be without liability of
any party to any other party, except as provided in Section 4.  Notwithstanding
any such termination, the provisions of Sections 6, 7 and 8 shall remain in
effect.

          Section 6.  Indemnification.  (a)  The Company agrees to indemnify and
                      ---------------                                           
hold harmless each Underwriter and each person, if any, who controls any
Underwriter within the meaning of Section 15 of the 1933 Act as follows:

          (i) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of an untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     (or any amendment thereto), including all documents incorporated therein by
     reference, or the omission or alleged omission therefrom of a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading or arising out of an untrue statement or alleged untrue
     statement of a material fact included in any preliminary prospectus
     supplement or the Prospectus (or any amendment or supplement thereto) or
     the omission or alleged omission therefrom of a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading;

          (ii) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, if such settlement is effected with
     the written consent of the Company; and

          (iii)  against any and all expense whatsoever, as incurred (including
     fees and disbursements of counsel chosen by you), reasonably incurred in
     investigating, preparing or defending against any litigation, or
     investigation or proceeding by any governmental agency or body, commenced
     or threatened, or any claim whatsoever
<PAGE>
 
                                       23

     based upon any such untrue statement or omission, or any such alleged
     untrue statement or omission, to the extent that any such expense is not
     paid under subparagraph (i) or (ii) above;

provided, however, that this indemnity agreement does not apply to any loss,
- --------  -------                                                           
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
Underwriter through you expressly for use in the Registration Statement (or any
amendment thereto) or any preliminary prospectus supplement or the Prospectus
(or any amendment or supplement thereto).

          The foregoing indemnity with respect to any untrue statement contained
in or any omission from a preliminary prospectus supplement, shall not inure to
the benefit of any Underwriter (or any person controlling such Underwriter) on
account of any loss, claim, damage, liability or litigation arising from the
sale of Offered Securities to any person by such Underwriter if such Underwriter
failed to send or give a copy of the Prospectus, as the same may be supplemented
or amended, to such person within the time required by the 1933 Act, and the
untrue statement or alleged untrue statement or omission or alleged omission of
a material fact in such preliminary prospectus supplement was corrected in the
Prospectus, unless such failure resulted from noncompliance by the Company with
its obligations hereunder to furnish the Underwriters with copies of the
Prospectus.

          (b) Each Underwriter severally agrees to indemnify and hold harmless
the Company, its directors, each of its officers who signed the Registration
Statement, and each person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act, against any and all loss, liability, claim,
damage and expense described in the indemnity agreement in Section 6(a), as
incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment thereto) or any preliminary prospectus supplement or the Prospectus
(or any amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Company by such Underwriter through you
expressly for use in the Registration Statement (or any amendment thereto) or
such preliminary prospectus supplement or the Prospectus (or any amendment or
supplement thereto).

          (c) Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, but failure to so notify an indemnifying
party shall not relieve it from any liability which it may have otherwise than
on account of this indemnity agreement.  An indemnifying party may participate
at its own expense in the defense of such action.  In no event shall the
indemnifying party or parties be liable for the fees and expenses of more than
one counsel for all indemnified parties in connection with any one action or
separate but similar or
<PAGE>
 
                                       24

related actions in the same jurisdiction arising out of the same general
allegations or circumstances.

          Section 7.  Contribution.  In order to provide for just and equitable
                      ------------                                             
contribution in circumstances under which the indemnity provided for in Section
6 is for any reason held to be unenforceable by the indemnified parties although
applicable in accordance with its terms, the Company and the Underwriters shall
contribute to the aggregate losses, liabilities, claims, damages and expenses of
the nature contemplated by such indemnity incurred by the Company and one or
more of the Underwriters, as incurred, in such proportions that the Underwriters
are responsible for that portion represented by the percentage that the
underwriting discount hereunder with respect to the offering of the Offered
Securities bears to the initial public offering price of the Offered Securities,
and the Company is responsible for the balance; provided, however, that no
                                                --------  -------         
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.  For purposes of this Section,
each person, if any, who controls an Underwriter within the meaning of Section
15 of the 1933 Act shall have the same rights to contribution as such
Underwriter, and each director of the Company, each officer of the Company who
signed the Registration Statement, and each person, if any, who controls the
Company within the meaning of Section 15 of the 1933 Act shall have the same
rights to contribution as the Company.

          Section 8.  Agreements to Survive Delivery.  The indemnities,
                      ------------------------------                   
agreements and other statements of the Company or its officers set forth in or
made pursuant to this Agreement will remain operative and in full force and
effect regardless of any investigation made by or on behalf of the Company, any
Underwriter or any person who controls the Company or any Underwriter within the
meaning of Section 15 of the 1933 Act and will survive delivery of and payment
for the Offered Securities.

          Section 9.  Termination of Agreement.  (a)  You may terminate this
                      ------------------------                              
Agreement, by notice to the Company, at any time at or prior to the Closing Time
(i) if there has been, since the respective dates as of which information is
given in the Registration Statement, any material adverse change or any
development involving a prospective material adverse change in or affecting the
financial position, stockholders' equity or results of operations of the Company
and its subsidiaries, considered as one enterprise, or (ii) if there has
occurred any outbreak or escalation of hostilities or other calamity or crisis
the effect of which on the financial markets of the United States is such as to
make it, in your judgment, impracticable to market the Offered Securities or
enforce contracts for the sale of the Offered Securities or (iii) if trading in
any securities of the Company has been suspended by the Commission or the
National Association of Securities Dealers, Inc., or if trading generally on
either the American Stock Exchange or the New York Stock Exchange or in the
over-the-counter market has been suspended, or minimum or maximum prices for
trading
<PAGE>
 
                                       25

have been fixed, or maximum ranges for prices for securities have been required,
by such exchange or by order of the Commission, the National Association of
Securities Dealers, Inc. or any other governmental authority or (iv) if a
banking moratorium has been declared by either federal or New York authorities.

          (b) If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party, except
to the extent provided in Section 4.  Notwithstanding any such termination, the
provisions of Sections 6, 7 and 8 shall remain in effect.

          Section 10.  Default.  If one or more of the Underwriters shall fail
                       -------                                                
at the Closing Time to purchase the Offered Securities that it or they are
obligated to purchase (the "Defaulted Offered Securities"), you shall have the
right, within 24 hours thereafter, to make arrangements for one or more of the
non-defaulting Underwriters, or any other underwriters, to purchase all, but not
less than all, of the Defaulted Offered Securities in such amounts as may be
agreed upon and upon the terms herein set forth; if, however, you have not
completed such arrangements within such 24-hour period, then:

          (a) if the aggregate principal amount of Defaulted Offered Securities
     does not exceed 10% of the aggregate principal amount of the Offered
     Securities to be purchased pursuant to this Agreement, the non-defaulting
     Underwriters shall be obligated to purchase the full amount thereof in the
     proportions that the principal amounts of Offered Securities set forth
     opposite the names of such non-defaulting Underwriters in Schedule I bear
     to the total aggregate principal amount of Offered Securities set forth
     opposite the names of such non-defaulting Underwriters, or

          (b) if the aggregate principal amount of Defaulted Offered Securities
     exceeds 10% of the aggregate principal amount of the Offered Securities to
     be purchased, this Agreement shall terminate without liability on the part
     of any non-defaulting Underwriter.

          No action taken pursuant to this Section shall relieve any defaulting
Underwriter from liability in respect of its default.

          In the event of any such default that does not result in a termination
of this Agreement, either you or the Company shall have the right to postpone
the Closing Time for a period not exceeding seven days in order to effect any
required changes in the Registration Statement or Prospectus or in any other
documents or arrangements.  As used herein, the term "Underwriter" includes any
person substituted for an Underwriter under this Section 10.

          Section 11.  Notices.  All notices and other communications hereunder
                       -------

          and its subsidiaries within the meaning of the 1933 Act and the
          applicable published 1933 Act Regulations;

               (b) in their opinion, except as disclosed in the Registration
          Statement, the audited consolidated financial statements and the
          related financial statement schedules of the Company and its
          subsidiaries included or incorporated by reference in such annual
          report on Form 10-K comply as to form in all material respects with
          the applicable accounting requirements of the 1933 Act as it applies
          to registration statements on Form S-3 and the related published 1933
          Act Regulations and of the 1934 Act as it applies to Form 10-K and the
          related published 1934 Act Regulations; and

               (c) in addition to their examinations, inspections, inquiries and
          other procedures referred to therein, they have performed such other
          procedures, specified by you, not constituting an audit, as they have
          agreed to perform and report on with respect to certain amounts,
          percentages, numerical data and other financial information in the
          Form 10-K and have compared certain of such amounts, percentages,

     quarterly reports on Form 10-Q (each a "10-Q Letter") filed prior to the
     date hereof and subsequent to the Company's most recently filed annual
     report on Form 10-K, to the effect that:

               (a) they reaffirm as of the date of such letter (and as though

          specified date not more than five days prior to the date of such 10-Q
          Letter;

               (b) on the basis of procedures (but not an examination in
          accordance with generally accepted auditing standards) consisting of:

                    (i) a reading of minutes of all meetings of the stockholders
               and directors of the Company and its subsidiaries and the
               __________ and ___________ Committees of the Company's Board of
               Directors and any subsidiary committees from the date of the
               latest audited consolidated financial statements to the specified

                    (iii)  inquiries of certain officials of the Company and its
               subsidiaries; and

          nothing came to their attention that caused them to believe that the
          unaudited condensed consolidated financial statements included or
          incorporated by reference in such quarterly report on Form 10-Q do not
          comply as to form in all material respects with the applicable
          accounting requirements of the 1934 Act as it applies to Form 10-Q and
          the related published 1934 Act Regulations or that any material
          modifications should be made to the unaudited condensed consolidated
          financial statements included or incorporated by reference in such
          quarterly report for them to be in conformity with generally accepted

          unaudited condensed consolidated financial statements or as otherwise
          described in such 10-Q Letter;

               (c) in addition to their examinations, inspections, inquiries and
          other procedures referred to therein, they have performed such other

          items to be in agreement with or derived from, the detailed accounting
          records of the Company and its subsidiaries.

          (3) At the Closing Time, a letter dated the Closing Time (the "Closing
     Letter"), to the effect that:

               (a) they reaffirm as of the date of the Closing Letter (and as
          though made on the date of the Closing Letter) all statements made in
          the 10-K Letter and in each 10-Q Letter, if any, except that the
          procedures specified therein shall have been carried out to a
          specified date not more than five days prior to the date of the
          Closing Letter;

               (b) based on the procedures set forth in Section 2(b) (but
          carried out to the specified date referred to in Section 3(a)),
          nothing came to their attention that caused them to believe that, from
          the date of the latest balance sheet of the Company and its
          subsidiaries included or incorporated by reference in the Prospectus
          to such specified date, there were any increases or decreases in
          financial statement amounts specified by you as they have agreed to
          perform; and

               (c) in addition to their examinations, inspections, inquiries and
          other procedures referred to therein, they have performed such other

          Registration Statement, the Prospectus and the exhibits to the
          Registration Statement or in the documents incorporated by reference
          in the Prospectus, and have compared certain of such amounts,
          percentages, numerical data and financial information with, and have
          found such items to be in agreement with or derived from, the detailed
          accounting records of the Company and its subsidiaries.

legally available for the payment of dividends, cash dividends on each
outstanding share of Series I Preferred Stock, at a rate per annum equal to 8

payable with respect to each Dividend Period.  All dividends shall be cumulative
and shall be payable in arrears for each Dividend Period on each Dividend
Payment Date, commencing on January 1, 1996.

          (B) Each dividend paid on the Series I Preferred Stock shall be
payable to Holders of record as their names shall appear in the stock ledger of
the corporation on the Dividend Record Date for such dividend, except that
dividends in arrears for any past Dividend Payment Date may be declared and paid
at any time without reference to such regular Dividend Payment Date to Holders

I Preferred Stock on the day prior to the Exchange Date or on the day prior to

failed to issue the appropriate aggregate principal amount of Exchange

with respect to such shares of Series I Preferred Stock.

          (D) All dividends paid with respect to shares of the Series I

apart sufficient for such payment, on the Series I Preferred Stock and any
Parity Securities for all dividend periods terminating on or prior to the date
of payment of such full dividends on the Series I Preferred Stock or such Parity
Securities.  If any dividends are not paid in full, as aforesaid, upon the
shares of the
<PAGE>
 
                                       10

Series I Preferred Stock and any other Parity Securities, all dividends declared
upon shares of the Series I Preferred Stock and any other Parity Securities
shall be declared pro rata so that the amount of dividends declared per share on
the Series I Preferred Stock and such Parity Securities shall in all cases bear
to each other the same ratio that accrued and unpaid dividends per share on the
Series I Preferred Stock and such Parity Securities bear to each other.  Except
as contemplated herein, no interest or additional dividends, or sum of money in
lieu of interest or additional dividends, shall be payable in respect of any
dividend payment or payments on the Series I Preferred Stock or any other Parity
Securities which may be in arrears.

          (F) So long as any shares of the Series I Preferred Stock are

corporation's stock incentive programs, 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 Securities, the
corporation shall not declare, pay or set apart for payment any dividend on any
Junior Securities (except dividends on Junior Securities payable in additional
shares of Junior Securities), or make any payment on account of, or set apart
for payment money for a sinking or other similar fund for, the purchase,
redemption or other retirement of, any of the Junior Securities or any warrants,
rights, calls or options exercisable for or convertible into any of the Junior
Securities, and shall not permit any corporation or other entity directly or
indirectly controlled by the corporation to purchase or redeem any of the Junior
Securities or any warrants, rights, calls or options exercisable for or
convertible into any of the Junior Securities, unless prior to or concurrently
with such declaration, payment, setting apart for payment, purchase, redemption
or distribution, as the case may be, all accrued and unpaid dividends on shares
of the Series I Preferred Stock not paid on the dates provided for in Section
IV(A) hereof (and, to the extent previously due but not yet paid, any and all
redemption payments on the Series I Preferred Stock) shall have been or are
concurrently being paid.

          (G) Dividends payable on shares of the Series I Preferred Stock for
any period less than a year shall be computed on the basis of a 360-day year of
twelve 30-day months and the actual number of days elapsed in the period for
which payable.  If any Dividend Payment Date occurs on a day that is not a
Business Day, any accrued dividends otherwise payable on such Dividend Payment
Date shall be paid on the next succeeding Business Day.

V.   Payment on Liquidation.
     ---------------------- 

          (A) Upon any voluntary or involuntary liquidation, dissolution or
winding-up of the affairs of the corporation, Holders will be entitled to
receive out of the assets of the corporation available for distribution to the
holders of its Capital Stock, whether such assets are capital, surplus or
earnings, an amount in cash equal to the Liquidation Preference, before any
payment shall be made or any assets distributed to the holders of any of the
Junior Securities.  Except as set forth in the preceding sentence, Holders shall
not be entitled to any distribution in the event of voluntary or involuntary
liquidation, dissolution or winding-up of the affairs of the corporation.  If
upon any voluntary or involuntary liquidation, dissolution or winding-up of the
affairs of the corporation, the assets of the corporation are not sufficient to
pay in full the liquidation payments payable to the holders of outstanding
shares of the Series I Preferred Stock and all Parity Securities, then the
holders of all such shares shall share equally and ratably in any distribution
of assets in proportion to the full liquidation preferences, determined as of
the date of such voluntary or involuntary liquidation, dissolution or winding-
up, to which they are entitled.

          (B) For the purposes of this Section V only, neither the sale, lease,
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
corporation nor the consolidation or merger of the corporation with or into one
or more corporations shall be deemed to be a liquidation, dissolution or
winding-up of the affairs of the corporation.


VI.  Redemption.
     ---------- 

          (A) Optional Redemption.  (i)  The corporation may, at its option,
              -------------------

<PAGE>
 
                                       12

          (ii) In the event of a redemption pursuant to this Section VI(A) of
only a portion of the then outstanding shares of Series I Preferred Stock, the
corporation shall effect such redemption pro rata according to the number of
shares held by each Holder of such Series I Preferred Stock or by lot, as
determined by the corporation, except that the corporation 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
determined by the corporation in its sole discretion.

          (B) Procedure for Redemption.  (i)  Not more than sixty (60) and not
              ------------------------                                        
less than thirty (30) days prior to the date fixed for any redemption of the
Series I Preferred Stock, written notice (the "Redemption Notice") shall be
given by first-class mail, postage prepaid, to each Holder of record of shares
to be redeemed on the record date fixed for such redemption of the Series I
Preferred Stock at such Holder's address as the same appears on the stock ledger
of the corporation, provided, however, that no failure to give such notice nor
any deficiency therein shall affect the validity of the procedure for the
redemption of any shares of Series I Preferred Stock to be redeemed except as to
the Holder or Holders to whom the corporation has failed to give such notice or
except as to the Holder or Holders whose notice was defective.  The Redemption
Notice shall state:

Preferred Stock to be redeemed shall surrender the certificate or certificates
representing such shares of  Series I Preferred Stock to the corporation, in the
manner and at the place designated in the Redemption Notice, and on the
Redemption Date the full Optional Redemption Price for such shares shall be
payable in cash to the Person whose name appears on such certificate or
certificates as the owner thereof, and each surrendered certificate shall be
returned to authorized but unissued shares.  In the event that less than all of
the shares represented by any such certificate are redeemed, a new certificate
shall be issued representing the unredeemed shares.

          (iii) Unless the corporation defaults in the payment in full
of the Optional Redemption Price, dividends on the Series I Preferred Stock
called for redemption shall cease to accumulate on the day prior to the
Redemption Date, and the Holders of such shares shall cease to have any further
rights with respect thereto on the Redemption Date, other than the right to
receive the Optional Redemption Price, without interest.

          (iv) If a Redemption Notice shall have been duly given, and if, on or
before the Redemption Date specified therein, all funds necessary for such
redemption shall have been set aside by the corporation, separate and apart from
its other funds, in trust for the pro rata benefit of the Holders of the Series
I Preferred Stock called for redemption so as to be and continue to be available
therefor, then, notwithstanding that any certificate for shares so called for
redemption shall not have been surrendered for cancellation, all shares so
called for redemption shall no longer be deemed outstanding, and all rights with
respect to such shares shall forthwith on such Redemption Date cease and
terminate, except only the right of the Holders thereof to receive the amount
payable on redemption thereof, without interest.

          (v) If a Redemption Notice shall have been duly given or if the
corporation shall have given to the bank or trust company hereinafter referred
to irrevocable authorization promptly to give such notice, and if on or before
the Redemption Date specified therein the funds necessary for such redemption
shall have been deposited by the corporation with such bank or trust company in
trust for the pro rata benefit of the Holders of the Series I Preferred Stock
called for redemption, then, notwithstanding that any certificate for shares so
called for redemption shall not have been surrendered for cancellation, from and
after the time of such deposit, all shares so called, or to be so called
pursuant to such irrevocable authorization, for redemption shall no longer be
deemed to be outstanding and all rights with respect of such shares shall
forthwith cease and terminate, except only the right of the Holders thereof to
receive from such bank or trust company at any time after the time of such
deposit the funds so deposited, without interest, and the right of the Holders
thereof to convert such shares as provided in Section IX hereof to and including
the fifth Business Day preceding the date fixed for redemption.  The aforesaid
bank or trust company shall be organized and in good standing under the laws of

<PAGE>

profits aggregating at least $100,000,000 according to its last published
statement of condition, and shall be identified in the Redemption Notice.  Any
interest accrued on such funds shall be paid to the corporation from time to
time.  Any funds so set aside or deposited, as the case may be, in respect of
shares of the Series I Preferred Stock that are subsequently converted shall be
promptly returned to the corporation.  Any funds so set aside or deposited, as
the case may be, and unclaimed at the end of three years from such Redemption
Date shall, to the extent permitted by law, be released or repaid to the
corporation, after which repayment the Holders of the shares so called for
redemption shall look only to the corporation for payment thereof.

          (vi) In connection with any redemption of shares of Series I Preferred
Stock, the corporation may arrange for the purchase and conversion of any such
shares by an agreement with one or more investment bankers or other purchasers
to purchase such shares by paying to the Holders or to the Conversion Agent in
trust for such Holders, on or before the close of business on the day prior to
the Redemption Date, an amount, in cash, not less than the Optional Redemption
Price payable by the Company on redemption of such shares.  Notwithstanding
anything to the contrary contained herein, the obligation of the Company to pay
the Optional Redemption Price of such shares of Series I Preferred Stock shall
be satisfied and discharged to the extent such amount is so paid by such
purchasers.  Pursuant to such an agreement, any such shares of Series I
Preferred Stock tendered by the Holders for redemption or not duly surrendered
for conversion by such Holders shall be deemed acquired by such purchasers from
such Holders and (notwithstanding anything to the contrary contained in Section
IX(A) hereof) surrendered by such purchasers for conversion, all as of
immediately prior to the close of business on the day prior to the Redemption
Date, subject to payment of the above as aforesaid.


VII.           Voting Rights.
               ------------- 

          (A) Holders, except as otherwise required under Delaware law and as
set forth in paragraphs (B) and (C) below, shall not be entitled or permitted to

the corporation.

          (B) Without the approval 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, as one class, given in person or by proxy, either in writing or by
resolution adopted at an annual or special meeting called for the purpose, the
corporation will not (i) create, authorize or issue any Senior Securities or any
warrants, rights, calls or options exercisable or exchangeable for or

Parity Securities or other outstanding Capital Stock of
<PAGE>
 
                                       15

the corporation into any Senior Securities or any warrants, rights, calls or
options exercisable or exchangeable for or convertible into, or any obligations
evidencing the right to purchase or acquire, any Senior Securities.

          (C) Without the approval 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, as one class, given in person or by proxy, either in writing or by
resolution adopted at an annual or special meeting called for the purpose, the
corporation will not amend, modify or repeal this Certificate of Designations so
as to affect adversely the specified designations, rights, preferences,
privileges or voting rights of the Series I Preferred Stock. The authorization
or consummation of a transaction which results in the Series I Preferred Stock
being converted into or exchanged for or becoming shares of a resulting entity
(as such term is defined in Section X) will not constitute an amendment,
modification or repeal of this Certificate of Designations for purposes of this
Section VII.

          (D) Prior to the exchange of Series I Preferred Stock for Exchangeable
Debentures, the corporation shall not amend or modify the indenture dated
November 1, 1995, between the corporation and the Trustee for the Exchange
Debentures, as supplemented by a supplemental indenture dated as of November 1,
1995 (as so supplemented, the "Exchange Indenture"), a copy of which is on file
at the principal executive offices of the corporation, without the affirmative
vote or consent of Holders of at least a majority of the shares of  Series I
Preferred Stock then outstanding, voting or consenting, as the case may be, as
one class, given in person or by proxy, either in writing or by resolution
adopted at an annual or special meeting called for the purpose; provided that
the corporation and the Trustee shall be permitted, without any vote or consent
of the Holders, to effect any amendments to the Exchange Indenture that could
have been effected under the Exchange Indenture without the consent of holders
of Exchange Debentures if any Exchange Debentures were then outstanding.

          (E) The 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, as
one class, whether voting in person or by proxy, either in writing or by
resolution adopted at an annual or special meeting called for the purpose, may
waive compliance with any provision of this Certificate of Designations.

          (F) Notwithstanding anything herein to the contrary, (i) the creation,
authorization or issuance of any shares of any Parity Securities or Junior
Securities or (ii) 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 and shall not be deemed to affect adversely the rights,
preferences, privileges or voting rights of Holders.

          (G) (i)  In the event that dividends on the Series I Preferred Stock

shall be adjusted to permit the Holders of a majority of the shares of Series I
Preferred Stock then outstanding, voting as one class, to elect one member of
the Board of Directors of the corporation and a second member of the Board of
Directors if the right to elect a second director is required by the ASE or any
other national securities exchange on which the corporation elects to list the
Class A Common Stock or by the requirements of the NASDAQ National Market System
if the corporation elects to have the Class A Common Stock traded thereon.  The
foregoing event described herein is a "Voting Rights Triggering Event".  Holders
of a majority of the issued and outstanding shares of Series I Preferred Stock,
voting as one class, shall thereupon have the exclusive right to elect one or
two members of the Board of Directors, as the case may be, at any annual or
special meeting of stockholders or at a special meeting of the Holders called as
hereinafter provided.

          (ii) The right of the Holders to vote pursuant to Section VII(G)(i) to
elect one or two members of the Board of Directors, as the case may be, as
aforesaid, shall continue until such time as all accumulated dividends that are
in arrears on the Series I Preferred Stock are paid in full, at which time the
special right of the Holders to vote for the election of one or two directors,
as the case may be, and the term of office of such director or directors elected
by the Holders shall terminate, and the number of directors constituting the
Board of Directors shall be reduced accordingly.  At any time after voting power
to elect one or two directors shall have become vested and be continuing in the
Holders pursuant to Section VII(G)(i) hereof, or if a vacancy shall exist in the
office of a director elected by the Holders, a proper officer of the corporation
may, and upon the written request of the Holders of record of at least twenty
percent (20%) of the shares of Series I Preferred Stock then outstanding
addressed to the Secretary of the corporation shall, call a special meeting of
the Holders for the purpose of electing the one or two directors, as the case
may be, which such Holders are entitled to elect as herein provided.  If such
meeting shall not be called by a proper officer of the corporation within 20
days after personal service of such written request upon the Secretary of the
corporation, or within 20 days after mailing the same within the United States
by certified mail, addressed to the Secretary of the corporation at its
principal executive offices, then the Holders of record of at least twenty
percent (20%) of the outstanding shares of Series I Preferred Stock may
designate in writing one of their number to call such meeting at the expense of
the corporation, and such meeting may be called by the Person so designated upon
the notice required for annual meetings of stockholders of the corporation and
shall be held at the place for holding annual meetings of stockholders.
Notwithstanding the provisions of this Section VII(G)(ii), no such special
meeting shall be called if any such request is received less than 60 days before
the date fixed for the next ensuing annual or special meeting of stockholders of
the corporation.  Any Holder so designated shall have access to the list of
Holders entitled to attend the meeting pursuant to the provisions hereof.

                                       17

          (iii)  At any meeting held for the purpose of electing directors at
which the Holders shall have the right, voting as one class, to elect one or two
directors, as the case may be, as aforesaid, the presence in person or by proxy
of the Holders of at least a majority of the outstanding Series I Preferred
Stock shall be required to constitute a quorum.

          (H) (i)  Any vacancy occurring in the office of a director elected by
the Holders may be filled by the remaining director, if any, or otherwise by the
departing director unless and until such vacancy shall be filled by the Holders.

          (ii) In any case in which the Holders shall be entitled to vote
pursuant to this Section VII or pursuant to Delaware law, each Holder of shares
of Series I Preferred Stock shall be entitled to one vote for each share of
Series I Preferred Stock held.


VIII. Exchange.
      -------- 

          (A) The corporation may, at its option, on any Dividend Payment Date
on or after January 1, 1998, exchange the shares of Series I Preferred Stock, in
whole but not in part, for the Exchange Debentures issued pursuant to the
Exchange Indenture (such date, the "Exchange Date").  Notwithstanding the
foregoing, the corporation may not exercise such exchange option unless (i) all
accrued and unpaid dividends in respect of shares of Series I Preferred Stock
surrendered to the corporation upon exchange shall have been paid or (ii) the
corporation has set aside funds to provide for the payment in full of such
dividends.  At least thirty (30) and not more than sixty (60) days prior to the
date fixed for exchange, the corporation shall send a written notice (the
"Exchange Notice") of exchange by mail to each Holder, which notice shall state:

               (a) that the corporation has elected to exchange the Series I
     Preferred Stock into Exchange Debentures pursuant to this Certificate of
     Designations;

               (b)  the Exchange Date;

               (c) that the Holder is to surrender to the corporation, at the
     place or places and in the manner designated in the Exchange Notice, its
     certificate or certificates representing the shares of Series I Preferred
     Stock;

               (d) that dividends on the shares of Series I Preferred Stock to
     be exchanged shall cease to accrue at the close of business on the day
     prior to the Exchange Date, whether or not certificates for shares of
     Series I Preferred Stock are surrendered for exchange on the Exchange Date,
     unless the corporation shall default in the delivery of Exchange
     Debentures; and
<PAGE>
 
                                       18

               (e) that interest on the Exchange Debentures shall accrue from
     the Exchange Date whether or not certificates for shares of Series I
     Preferred Stock are surrendered for exchange on the Exchange Date.

On the Exchange Date, if the conditions set forth in clauses (i) through (iv)
below are satisfied and if the exchange is then permitted under the Exchange
Indenture, the corporation shall issue Exchange Debentures in exchange for the
Series I Preferred Stock as provided in the next paragraph, provided that on the
Exchange Date:  (i) there shall be legally available funds sufficient for the
exchange to occur (including, without limitation, legally available funds
sufficient therefor under Sections 160 and 170 (or any successor provisions), to
the extent applicable, of the General Corporation Law of the State of Delaware;
(ii) the corporation shall have obtained a written opinion of counsel acceptable
to the corporation that an exemption from the registration requirements of the
Securities Act is available for such exchange, and such exemption is relied upon
by the corporation for such exchange or, alternatively, that the Exchange
Debentures have been registered thereunder; (iii) the Exchange Indenture and the
Trustee shall have been qualified under the Trust Indenture Act or the
corporation shall have obtained a written opinion of counsel that such
qualification is not required; and (iv) immediately after giving effect to such
exchange, no Default or Event of Default (each as defined in the Exchange
Indenture) would exist under the Exchange Indenture.  In the event that any of
the conditions set forth in clauses (i) through (iv) of the preceding sentence
are not satisfied on the Exchange Date, then no shares of Series I Preferred
Stock shall be exchanged, and in order to effect an exchange as provided for in
this Section VIII, the corporation shall be required to fix another date for the
exchange and issue a new Exchange Notice.

          (B) Upon any exchange pursuant to Section VIII(A), Holders shall be
entitled to receive a principal amount of Exchange Debentures equal to the
Liquidation Preference of Series I Preferred Stock, plus an amount in cash equal
to all accrued and unpaid dividends thereon for the period from the immediately
preceding Dividend Payment Date to the day prior to the Exchange Date; provided
that the corporation shall pay cash in lieu of issuing an Exchange Debenture in
a principal amount of less than $1,000 and provided further that the Exchange
Debentures will be issuable only in denominations of $1,000 and integral
multiples thereof.

          (C) On or before the Exchange Date, each Holder shall surrender the
certificate or certificates representing such shares of Series I Preferred
Stock, in the manner and at the place designated in the Exchange Notice.  The
corporation shall cause the Exchange Debentures to be executed on the Exchange
Date and, upon surrender in accordance with the Exchange Notice of the
certificates for any shares of Series I Preferred Stock so exchanged (properly
endorsed or assigned for transfer, if the Exchange Notice shall so state), such
shares shall be exchanged by the corporation into Exchange Debentures as
<PAGE>
 
                                       19

aforesaid.  The corporation shall pay interest on the Exchange Debentures at the
rate and on the dates specified therein from the Exchange Date.

          (D) If  the Exchange Notice has been mailed as aforesaid, and if
before the Exchange Date all Exchange Debentures necessary for such exchange
shall have been duly executed by the corporation and delivered to the Trustee
with irrevocable instructions to authenticate the Exchange Debentures necessary
for such exchange, then the rights of the Holders as stockholders of the
corporation shall cease (except the right to receive Exchange Debentures and
accrued and unpaid dividends to the Exchange Date and the right of the Holders
thereof to convert such shares as provided in Section IX hereof to and including
the fifth Business Day preceding the Exchange Date), and the Person or Persons
entitled to receive the Exchange Debentures issuable upon exchange shall be
treated for all purposes as the registered Holder or Holders of such Exchange
Debentures as of the date of exchange.  Upon the exchange of the Series I
Preferred Stock for Exchange Debentures, the rights of Holders as stockholders
of the corporation shall cease (except the right to receive the Exchange
Debentures and accrued and unpaid dividends), and the Person or Persons entitled
to receive the Exchange Debentures issuable upon exchange shall be treated for
all purposes as registered holder or holders of such Exchange Debentures as of
the date of exchange.


IX.  Conversion.
     ---------- 

          (A) General Rights.  Each share of Series I Preferred Stock shall be
              --------------                                                  
convertible, at any time after January 8, 1996, at the option of the Holder
thereof, (but if such share is called for redemption pursuant to Section VI or
exchange pursuant to Section VIII, then only to and including but not after the
close of business on the fifth Business Day preceding the date fixed for such
redemption (except with respect to deemed conversions as provided for in Section
VI(B)(vi)) or exchange, provided that no default by the corporation in the
payment of the applicable Optional Redemption Price or in the exchange of such
share, as the case may be, shall have occurred and be continuing on the date
fixed for such redemption or exchange, as the case may be, in which case such
right of conversion shall be reinstated), into that number of fully paid and
non-assessable shares of Class A Common Stock of the corporation (calculated as
to each conversion to the nearest 1/100th of a share) obtained by dividing the
Original Liquidation Preference of the shares of Series I Preferred Stock
surrendered for conversion by the Conversion Price (as defined below) then in
effect (such date of conversion, a "Conversion Date").

          The conversion price shall initially be $67.44 (the "Conversion
Price").

          In order to exercise the conversion privilege, a Holder shall
surrender the certificate(s) representing such shares, accompanied by transfer
instrument(s) satisfactory to the corporation and sufficient to transfer the
Series I Preferred Stock being converted to the
<PAGE>
 
                                       20

corporation free of any adverse interest, at any of the offices or agencies
maintained for such purpose by the conversion agent designated by the
corporation (the "Conversion Agent") and shall give written notice to the
corporation that the Holder elects to convert such shares.  The initial
Conversion Agent shall be Harris Trust and Savings Bank, the transfer agent for
the Series I Preferred Stock.  Such notice shall also state the name(s),
together with address(es), in which the certificate(s) for shares of Class A
Common Stock shall be issued.  As promptly as practicable after the surrender of
such shares of Series I Preferred Stock as aforesaid, the corporation shall
issue and deliver at the office of such Conversion Agent to such Holder, or on
his written order, certificate(s) representing the number of full shares of
Class A Common Stock issuable upon the conversion of such shares in accordance
with the provisions hereof, and any fractional interest in respect of a share of
Class A Common Stock arising upon such conversion shall be settled as provided
for below.  Certificates will be issued representing the balance of any
remaining shares of Series I Preferred Stock in any case in which fewer than all
of the shares of Series I Preferred Stock represented by a certificate are
converted.  Each conversion shall be deemed to have been effected immediately
prior to the close of business on the date on which shares of Series I Preferred
Stock shall have been surrendered and notice received by the corporation as
aforesaid, and the Person(s) in whose name(s) any certificate(s) for shares of
Class A Common Stock shall be issuable upon such conversion shall be deemed to
have become the holder(s) of record of the Class A Common Stock represented
thereby at such time, unless the stock transfer books of the corporation shall
be closed on the date on which shares of Series I Preferred Stock are so
surrendered for conversion, in which event such conversion shall be deemed to
have been effected immediately prior to the close of business on the next
succeeding day on which such stock transfer books are open, and such person(s)
shall be deemed to have become such holder(s) of record of the Class A Common
Stock at the close of business on such later day.  In either circumstance, such
conversion shall be at the Conversion Price in effect on the date upon which
such share shall have been surrendered and such notice received by the
corporation.

          The dividend payable on a share of Series I Preferred Stock on a
Dividend Payment Date shall be payable to the Holder of record of such share at
the close of business on the Dividend Record Date applicable thereto,
notwithstanding the conversion of such share after such Dividend Record Date and
prior to the opening of business on such Dividend Payment Date or the default by
the corporation in the payment of the dividend due on such Dividend Payment
Date.  Except as provided in the next sentence, shares of Series I Preferred
Stock surrendered for conversion during the period from the close of business on
any Dividend Record Date to the opening of business on the Dividend Payment Date
with respect to such dividend shall be accompanied by payment in immediately
available funds or other funds acceptable to the corporation of an amount equal
to the dividend payable on such Dividend Payment Date on the shares of Series I
Preferred Stock being surrendered for conversion.  The dividend with respect to
a share of Series I Preferred Stock called for redemption on a Redemption Date
during the period from the fifth business day after a Dividend Record Date to
the fifth business day after the Dividend Payment Date shall be
<PAGE>
 
                                       21

payable on such Dividend Payment Date to the Holder of record of such share on
such Dividend Record Date notwithstanding the conversion of such share of Series
I Preferred Stock after the close of business on such Dividend Record Date and
prior to the opening of business on such Dividend Payment Date, and the Holder
converting such share of Series I Preferred Stock need not include a payment of
such dividend amount upon surrender of such share of Series I Preferred Stock
for conversion.  Except as provided in this paragraph, no payment or adjustment
shall be made upon any conversion on account of any dividends accrued on shares
of Series I Preferred Stock surrendered for conversion or on account of any
dividends on the Class A Common Stock issued upon conversion.

          No fractional interest in a share of Class A Common Stock shall be
issued by the corporation upon the conversion of any share(s) of Series I
Preferred Stock.  Any fractional interest in a share of Class A Common Stock
resulting from conversion of any share(s) of Series I Preferred Stock shall be
paid in cash (computed to the nearest cent) based on the Closing Price of the
Class A Common Stock on the last Trading Day prior to the date on which such
share or shares of Series I Preferred Stock are surrendered for conversion in
the manner set forth above.  If more than one certificate representing shares of
Series I Preferred Stock shall be surrendered for conversion at one time by the
same holder, the number of full shares issuable upon conversion thereof shall be
computed on the basis of the aggregate number of shares of Series I Preferred
Stock represented by such certificates which are to be converted.

         The Conversion Price shall be adjusted from time to time as follows:

               (a) In case the corporation shall pay or make a dividend or other
     distribution on any class of capital stock of the corporation in Class A
     Common Stock, the Conversion Price in effect at the opening of business on
     the day following the date fixed for the determination of stockholders
     entitled to receive such dividend or other distribution shall be reduced by
     multiplying such Conversion Price by a fraction the numerator of which
     shall be the number of shares of Class A Common Stock outstanding at the
     close of business on the date fixed for such determination and the
     denominator of which shall be the sum of such number of shares and the
     total number of shares constituting such dividend or other distribution,
     such reduction to become effective immediately after the opening of
     business on the day following the date fixed for such determination.  For
     the purposes of this subsection (a), the number of shares of Class A Common
     Stock at any time outstanding shall not include shares held in the treasury
     of the corporation.  The corporation will not pay any dividend or make any
     distribution on shares of Class A Common Stock held in the treasury of the
     corporation.

               (b) In case the corporation shall issue rights or warrants to all
     holders of its Class A Common Stock entitling them to subscribe for,
     purchase or acquire shares of
<PAGE>
 
                                       22

     Class A Common Stock at a price per share less than the current market
     price per share (determined as provided in subsection (f) below) of the
     Class A Common Stock on the date fixed for the determination of
     stockholders entitled to receive such rights or warrants, the Conversion
     Price in effect at the opening of business on the day following the date
     fixed for such determination shall be reduced by multiplying such
     Conversion Price by a fraction the numerator of which shall be the number
     of shares of Class A Common Stock outstanding at the close of business on
     the date fixed for such determination plus the number of shares of Class A
     Common Stock which the aggregate of the offering price of the total number
     of shares of Class A Common Stock so offered for subscription, purchase or
     acquisition would purchase at such current market price and the denominator
     of which shall be the number of shares of Class A Common Stock outstanding
     at the close of business on the date fixed for such determination plus the
     number of shares of Class A Common Stock so offered for subscription,
     purchase or acquisition, such reduction to become effective immediately
     after the opening of business on the day following the date fixed for such
     determination.  For the purposes of this subsection (b), the number of
     shares of Class A Common Stock at any time outstanding shall not include
     shares held in the treasury of the corporation.  The corporation will not
     issue any rights or warrants in respect of shares of Class A Common Stock
     held in the treasury of the corporation.

               (c) In case the outstanding shares of Class A Common Stock shall
     be subdivided into a greater number of shares of Class A Common Stock, the
     Conversion Price in effect at the opening of business on the day following
     the day upon which such subdivision becomes effective shall be
     proportionately reduced, and, conversely, in case the outstanding shares of
     Class A Common Stock shall each be combined into a smaller number of shares
     of Class A Common Stock, the Conversion Price in effect at the opening of
     business on the day following the day upon which such combination becomes
     effective shall be proportionately increased, such reduction or increase,
     as the case may be, to become effective immediately after the opening of
     business on the day following the day upon which such subdivision or
     combination becomes effective.

               (d) In case the corporation shall, by dividend or otherwise,
     distribute to all holders of its Class A Common Stock (i) evidences of its
     indebtedness and/or (ii) cash or other assets (excluding (x) any rights or
     warrants referred to in subsection (b) above, (y) any dividend or
     distribution referred to in subsection (a) above, and (z) cash dividends or
     distributions from earnings unless the sum of (1) all such cash dividends
     and distributions made within the preceding 12 months in respect of which
     no adjustment has been made and (2) any cash and the fair market value of
     other consideration paid in respect of any repurchases of Common Stock by
     the corporation or any of its subsidiaries within the preceding 12 months
     in respect of which no adjustment has been made, exceeds 20% of the
     corporation's market capitalization
<PAGE>
 
                                       23

     (being the product of the then current market price per share (determined
     as provided in subsection (f) below) of the Class A Common Stock times the
     aggregate number of shares of Class A Common Stock and Class B Common Stock
     then outstanding) on the record date for such distribution), then in each
     case, the Conversion Price in effect at the opening of business on the day
     following the date fixed for the determination of holders of Common Stock
     entitled to receive such distribution shall be adjusted by multiplying such
     Conversion Price by a fraction of which the numerator shall be the current
     market price per share (determined as provided in subsection (f) below) of
     the Class A Common Stock on such date of determination (or, if earlier, on
     the date on which the Class A Common Stock goes "ex-dividend" in respect of
     such distribution) less the then Fair Market Value as determined by the
     Board of Directors (whose determination shall be conclusive and shall be
     described in a statement filed with any Conversion Agent) of the portion of
     the other assets or evidences of indebtedness so distributed (and for which
     an adjustment to the Conversion Price has not previously been made pursuant
     to the terms of this Section IX) applicable to one share of Class A Common
     Stock, and the denominator shall be such current market price per share of
     the Class A Common Stock, such adjustment to become effective immediately
     after the opening of business on the day following such date of
     determination.  The following transactions shall be excluded from the
     foregoing clauses (1) and (2):  (i) any conversion of Class B Common Stock
     into Class A Common Stock, (ii) repurchases of Common Stock issued under
     the corporation's stock incentive programs, and (iii) 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 Securities.

               (e) The reclassification or change of Class A Common Stock into
     securities including securities other than Class A Common Stock (other than
     any reclassification upon a consolidation or merger to which subsection (i)
     below applies) shall be deemed to involve (i) a distribution of such
     securities other than Class A Common Stock to all holders of Common Stock
     (and the effective date of such reclassification shall be deemed to be "the
     date fixed for the determination of holders of Common Stock entitled to
     receive such distribution" within the meaning of subsection (d) above), and
     (ii) a subdivision or combination, as the case may be, of the number of
     shares of Class A Common Stock outstanding immediately prior to such
     reclassification into the number of shares of Class A Common Stock
     outstanding immediately thereafter (and the effective date of such
     reclassification shall be deemed to be "the day upon which such subdivision
     becomes effective" or "the day upon which such combination becomes
     effective," as the case may be, and "the day upon which such subdivision or
     combination becomes effective" within the meaning of subsection (c) above).

               (f) For the purpose of any computation under subsection (b) or
     (d) above, the current market price per share of Class A Common Stock on
     any day shall be
<PAGE>
 
                                       24

     deemed to be the average of the Closing Prices of the Class A Common Stock
     for the 20 consecutive Trading Days selected by the Board of Directors
     commencing no more than 30 Trading Days before and ending no later than the
     day before the day in question; provided that, in the case of clause (d),
     if the period between the date of the public announcement of the dividend
     or distribution and the date for the determination of holders of Class A
     Common Stock entitled to receive such dividend or distribution (or, if
     earlier, the date on which the Class A Common Stock goes "ex-dividend" in
     respect of such dividend or distribution) shall be less than 20 Trading
     Days, the period shall be such lesser number of Trading Days but, in any
     event, not less than five Trading Days.

               (g) No adjustment in the Conversion Price shall be required
     unless such adjustment would require an increase or decrease of at least 1%
     of such price; provided, however, that any adjustments which by reason of
     this clause (g) are not required to be made shall be carried forward and
     taken into account in any subsequent adjustment and provided further that
     adjustments shall be required and made in accordance with the provisions of
     this Section IX (other than this clause (g)) not later than such time as
     may be required in order to preserve the tax free nature of a distribution
     to the holders of shares of Class A Common Stock.  Anything in this clause
     (g) to the contrary notwithstanding, the corporation shall be entitled, at
     its option, to make such reductions in the Conversion Price, in addition to
     those required by this Section IX, as it in its discretion shall determine
     to be advisable in order that any stock dividend, subdivision or
     combination of shares, distribution of capital stock or rights or warrants
     to purchase stock or securities, or distribution of evidences of
     indebtedness or assets (other than cash dividends or distributions paid
     from earnings) or other event shall be a tax free distribution for federal
     income tax purposes.  All calculations under this clause (g) shall be made
     to the nearest cent.

               (h) Whenever the Conversion Price is adjusted as herein provided,
     the corporation shall promptly mail a certificate of a firm of independent
     public accountants setting forth the Conversion Price after such adjustment
     and setting forth a brief statement of the facts requiring such adjustment
     and the manner of computing same, which certificate shall constitute
     conclusive evidence, absent manifest error, of the correctness of such
     adjustment.  The certificate shall be mailed to each Holder at his last
     address as the same appears on the stock transfer books of the corporation
     and to the Conversion Agent.

               (i) In case of (i) any consolidation of the corporation with, or
     merger of the corporation into, any other entity, (ii) any merger of
     another entity into the corporation (other than a merger which does not
     result in any reclassification, conversion, exchange or cancellation of
     outstanding shares of Class A Common Stock) or (iii) any sale or transfer
     of all or substantially all of the assets of the
<PAGE>
 
                                       25

     corporation, each Holder shall have the right thereafter to convert such
     share 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 into which such share of
     Series I Preferred Stock might have been converted immediately prior to
     such consolidation, merger, sale or transfer, assuming such holder of Class
     A Common Stock is not an entity with which the corporation consolidated or
     into which the corporation merged or which merged into the corporation or
     to which such sale or transfer was made, as the case may be (a "constituent
     entity"), or an affiliate of a constituent entity and failed to exercise
     its rights of election, if any, as to the kind or amount of securities,
     cash or other property receivable upon such consolidation, merger, sale or
     transfer (provided that if the kind or amount of securities, cash and other
     property receivable upon such consolidation, merger, sale or transfer is
     not the same for each share of Class A Common Stock held immediately prior
     to such consolidation, merger, sale or transfer by other than a constituent
     entity or an affiliate thereof and in respect of which such rights of
     election shall not have been exercised ("non-electing share"), then for the
     purpose of this subsection (i) the kind and amount of securities, cash and
     other property receivable upon such consolidation, merger, sale or transfer
     by each non-electing share shall be deemed to be the kind and amount so
     receivable per share by a plurality of the non-electing shares).  If
     necessary, appropriate adjustment shall be made in the application of the
     provisions set forth herein with respect to the rights and interests
     thereafter of the Holders, to the end that the provisions set forth herein
     shall thereafter correspondingly be made applicable, as nearly as may
     reasonably be, in relation to any shares of stock or other securities or
     property thereafter deliverable on the conversion of the shares.  Any such
     adjustment shall be evidenced by a certificate of independent public
     accountants and a notice of such adjustment filed and mailed in the manner
     set forth in subsection (h) above and containing the information set forth
     in such subsection (h), and any adjustment so certified, shall for all
     purposes hereof conclusively be deemed to be an appropriate adjustment,
     absent manifest error.  The above provisions shall similarly apply to
     successive consolidations, mergers, sales or transfers.

          For purposes of this Section IX, "Class A Common Stock" includes any
stock of any class of the corporation (other than Class B Common Stock) which
has no preference in respect of dividends or of amounts payable in the event of
any voluntary or involuntary liquidation, dissolution or winding-up of the
corporation and which is not subject to redemption by the corporation.  However,
subject to the provisions of subsection (i) above, shares issuable on conversion
of shares of Series I Preferred Stock shall include only shares of the class
designated as Common Stock of the corporation on the date of the initial
issuance of Series I Preferred Stock by the corporation, or shares of any class
or classes resulting from any reclassification thereof and which have no
preferences in respect of dividends or amounts payable in the event of any
voluntary or involuntary liquidation, dissolution or
<PAGE>
 
                                       26

winding-up of the corporation and which are not subject to redemption by the
corporation; provided that, if at any time there shall be more than one such
resulting class, the shares of each such class then so issuable shall be
substantially in the proportion which the total number of shares of such class
resulting from all such reclassifications bears to the total number of shares of
all such classes resulting from all such reclassifications.

               In case:

               (i) the corporation shall take any action that would result in an
     adjustment to the Conversion Price; or

               (ii) of any consolidation, merger or share exchange to which the
     corporation is a party and for which approval of any stockholders of the
     corporation is required, or of the sale or transfer of all or substantially
     all of the assets of the corporation; or

               (iii)  of the voluntary or involuntary dissolution, liquidation
     or winding-up of the corporation;

then the corporation shall cause to be filed with any Conversion Agent and shall
cause to be mailed to each Holder at its last address as the same appears on the
books of the corporation, at least 15 days prior to the applicable record or
effective date hereinafter specified, a notice stating (A) the date on which a
record is to be taken for the purpose of such actions, or, if the record is not
to be taken, the date as of which the holders of Class A Common Stock of record
are to be determined, or (B) the date on which such consolidation, merger, share
exchange, sale, transfer, dissolution, liquidation or winding-up is expected to
become effective, and the date as of which it is expected that holders of Class
A Common Stock of record shall be entitled to exchange their shares of Class A
Common Stock for securities, cash or other property deliverable upon such
consolidation, merger, share exchange, sale, transfer, dissolution, liquidation
or winding-up.  Neither the failure to give such notice nor any defect therein
shall affect the legality or validity of the proceedings described in clauses
(i) through (iii) above.

          The corporation will pay any and all documentary stamp or similar
issue or transfer taxes payable in respect of the issue or delivery of shares of
Class A Common Stock on conversion of shares of Series I Preferred Stock
pursuant hereto; provided, however, that the corporation shall not be required
to pay any tax which may be payable in respect of any transfer involved in the
issue or delivery of shares of Class A Common Stock in a name other than that of
the Holder of the shares of Series I Preferred Stock to be converted, and no
such issue or delivery shall be made unless and until the Person requesting such
issue or delivery has paid to the corporation the amount of any such tax or has
established, to the satisfaction of the corporation, that such tax has been
paid.
<PAGE>
 
                                       27

          The corporation covenants that all shares of Class A Common Stock
which may be issued upon conversions of shares of Series I Preferred Stock will,
upon issue, be duly and validly issued, fully paid and non-assessable, free of
all liens and charges and not subject to any preemptive rights.

          The corporation covenants that it will at all times reserve and keep
available, free from preemptive rights, out of the aggregate of its authorized
but unissued shares of Class A Common Stock, for the purpose of effecting
conversions of shares of Series I Preferred Stock, the full number of shares of
Class A Common Stock deliverable upon the conversion of all outstanding shares
of Series I Preferred Stock not theretofore converted.

          (B) Special Conversion Rights upon Change of Control.  (1)  Upon the
              ------------------------------------------------                
occurrence of a Change of Control, each Holder shall have the right, at the
Holder's option, during the Special Conversion Exercise Period to convert all,
but not less than all, of such Holder's Series I Preferred Stock into Class A
Common Stock at an adjusted Conversion Price per share equal to the Special
Conversion Price.  The corporation may, at its option, in lieu of providing
Class A Common Stock upon any such conversion, provide the Holder, out of funds
legally available therefor, with cash equal to the Market Value of the Class A
Common Stock multiplied by the number of shares of Class A Common Stock into
which such shares of Series I Preferred Stock would have been convertible
immediately prior to such Change of Control at an adjusted Conversion Price
equal to the Special Conversion Price.  Series I Preferred Stock which becomes
convertible pursuant to a special conversion right shall, unless so converted,
remain convertible into Class A Common Stock as provided pursuant to Section
IX(A).  If a Change of Control involves a consolidation, merger or sale of
assets of the corporation, the Holders exercising their conversion rights will
be entitled to receive the same consideration as would be received by a holder
of the number of shares of Class A Common Stock into which their shares of
Series I Preferred Stock would have been converted pursuant to their special
conversion rights.

          (2) Upon the occurrence of a Change of Control, within 30 days after
such occurrence, the corporation shall mail to each Holder a notice of such
occurrence (the "Special Conversion Notice") setting forth the following:

               (i) the event constituting the Change of Control, together with
     such other information as may be required pursuant to the securities laws;

               (ii) the Special Conversion Exercise Period and the Special
     Conversion Termination Date;

               (iii)  the Special Conversion Price;
<PAGE>
 
                                       28

               (iv) the Conversion Price then in effect and the continuing
     conversion rights, if any, under Section IX(A);

               (v) the name and address of the paying agent and Conversion
     Agent;

               (vi) that the Holders who want to convert shares of Series I
     Preferred Stock at the Special Conversion Price must exercise such
     conversion right during the Special Conversion Exercise Period;

               (vii)  that exercise of such special conversion right shall be
     irrevocable except that Holders shall have the right to withdraw their
     election to exercise the special conversion right at any time prior to the
     close of business on the Special Conversion Termination Date by providing
     written, telegraphic or facsimile transmission notice of withdrawal to the
     Conversion Agent, which notice, to be effective, must be received by the
     Conversion Agent prior to the close of business on the Special Conversion
     Termination Date;

               (viii)  that no dividends on shares of Series I Preferred Stock
     (or portions thereof) tendered for conversion (and not withdrawn) shall
     accrue from and after the Special Conversion Termination Date; and

               (ix) that the corporation (or a successor entity, if applicable)
     may, at its option, elect to pay cash (specifying the amount thereof per
     share) for all shares of Series I Preferred Stock tendered for conversion.

          (3) A Holder must exercise the special conversion right during the
Special Conversion Exercise Period or such special conversion right shall
expire.  Such right must be exercised in accordance with Section IX(A) to the
extent the procedures in Section IX(A) are consistent with the special
provisions of Section IX(B)(2) and this Section IX(B)(3).  Exercise of such
conversion right shall, except as provided above, be irrevocable, and dividends
on Series I Preferred Stock tendered for conversion shall cease to accrue from
and after the Special Conversion Termination Date.  The conversion date with
respect to the exercise of a special conversion right arising upon a Change of
Control shall be the Special Conversion Termination Date.

 
X.   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 I Preferred Stock, the
corporation 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
<PAGE>
 
                                       29

such consolidation or merger (if other than the corporation) 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, than the Series I Preferred Stock had immediately prior to
such transaction (provided that (i) if, in accordance with the provisions
hereof, 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 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 for purposes of this Section X); and (c) immediately
after giving effect to such transaction, no Voting Rights Triggering Event shall
have occurred and be continuing; provided, however, that the foregoing
provisions of this Section X shall not be applicable to a transaction or event
that constitutes a Change of Control.


XI.  Covenant to Report.
     ------------------ 

          Notwithstanding that the corporation may not be subject to the
reporting requirements of Section 13 or Section 15(d) of the Exchange Act, the
corporation will file with the SEC and provide the Transfer Agent and the
holders of the Series I Preferred Stock with all information, documents and
reports specified in Section 13 and Section 15(d) of the Exchange Act.


XII. Mutilated or Missing Series I Preferred Stock Certificates.
     ---------------------------------------------------------- 

          If any of the Series I Preferred Stock certificates shall be
mutilated, lost, stolen or destroyed, the corporation shall issue, in exchange
and in substitution for and upon cancellation of the mutilated Series I
Preferred Stock certificate, or in lieu of and substitution for the Series I
Preferred Stock certificate lost, stolen or destroyed, a new Series I Preferred
Stock certificate of like tenor and representing an equivalent amount of shares
of Series I Preferred Stock, but only upon receipt of evidence of such loss,
theft or destruction of such Series I Preferred Stock certificate and indemnity,
if requested, satisfactory to the corporation and the Transfer Agent (if other
than the corporation).

XIII.  Reissuance; Preemptive Rights.
       ----------------------------- 

          (i) Shares of Series I Preferred Stock that have been issued and
reacquired in any manner, including shares purchased or redeemed or exchanged,
shall (upon compliance with any applicable provisions of the laws of the State
of Delaware) have the status of authorized and unissued shares of preferred
stock undesignated as to series and may be redesignated and reissued as part of
any series of Additional Preferred Stock other than the Series I Preferred
Stock.

          (ii) No shares of Series I Preferred Stock shall have any rights of
preemption whatsoever as to any securities of the corporation, or any warrants,
rights or options issued or granted with respect thereto, regardless of how such
securities or such warrants, rights or options may be designated, issued or
granted.


XIV.   Business Day.
       ------------ 

          If any payment or redemption shall be required by the terms hereof to
be made on a day that is not a Business Day, such payment, redemption or
exchange shall be made on the immediately succeeding Business Day and no further
dividends shall accumulate after the day payment was required.


XV.  Headings of Subdivisions.
     ------------------------ 

          The headings of various subdivisions hereof are for convenience of
reference only and shall not affect the interpretation of any of the provisions
hereof.


XVI.  Severability of Provisions.
      -------------------------- 

          If any right, preference or limitation of the Series I Preferred Stock
set forth in these resolutions and the Certificate of Designations filed
pursuant hereto (as such Certificate of Designations may be amended from time to
time) is invalid, unlawful or incapable of being enforced by reason of any rule
or law or public policy, all other rights, preferences and limitations set forth

without the invalid, unlawful or unenforceable right, preference or limitation
shall, nevertheless remain in full force and effect, and no right, preference or
limitation herein set forth shall be deemed dependent upon any other such right,
preference or limitation unless so expressed herein.

     The Board of Directors of the Company has duly adopted resolutions
authorizing the Company to execute and deliver this Supplemental Indenture.

     All of the conditions and requirements necessary to make this Supplemental
Indenture, when duly executed and delivered, a valid and binding agreement in

anything to the contrary contained herein, Senior Indebtedness shall mean and
include all amounts of Senior Indebtedness that is such by virtue of clause (i)
or (ii) of the foregoing definition that are repaid by the Company and
subsequently recovered from the holder of such Senior Indebtedness under any
applicable Bankruptcy Laws or otherwise (other than by reasons of some wrongful
conduct on the part of the holders of such Debt).

                                  ARTICLE TWO

                            THE SERIES OF DEBENTURES
                            ------------------------

          SECTION 2.1.  Title of the Securities; Maturity.
                        ---------------------------------

          There shall be a series of Securities designated the "8-1/2%
Convertible Subordinated Debentures due 2007" (the "Exchange Debentures").  The
Exchange Debentures will mature on November 1, 2007.

          SECTION 2.2.  Limitation on Aggregate Principal Amount; Dates of 
                        --------------------------------------------------
                        Exchange Debentures.
                        ------------------- 

          The aggregate principal amount of the Exchange Debentures shall be
limited to $345,000,000.

          SECTION 2.3.  Interest and Interest Rates.
          -----------------------------------------  

          The Exchange Debentures will bear interest at a rate of 8-1/2% from
the Exchange Date or from the most recent Interest Payment Date to which
interest has been paid or provided for, payable semiannually in cash in arrears
on January 1 and July 1 of each year, commencing with the first such date after
the Exchange Date (each, an "Interest Payment Date"), to the Person in whose
name such Exchange Debenture is registered at the close of business on December
15 or June 15 next preceding such Interest Payment Date (each, a "Regular Record
Date").  Interest will be computed on the basis of a 360-day year comprised of
twelve 30-day months and actual number of days elapsed.   The interest so
payable on any Exchange Debenture which is not punctually paid or duly provided
for on any Interest Payment Date shall forthwith cease to be payable to the
Person in whose name such Exchange Debenture is registered on the relevant
Regular Record Date, and such defaulted interest shall instead be payable to the
Person in whose name such Exchange
<PAGE>
 
                                       6

Debenture is registered on the Special Record Date or other specified date
determined in accordance with the Indenture.

          SECTION 2.4.  Conversion of Exchange Debentures. 
                        ---------------------------------

          (a) Conversion Privilege and Conversion Price.
              ----------------------------------------- 

          Subject to and upon compliance with the provisions of this Article at
any time prior to redemption or maturity thereof, at the option of the Holder
thereof, any Exchange Debenture or any portion of the principal amount thereof
which is $1,000 or an integral multiple of $1,000 may be converted, at any time
prior to redemption or maturity thereof, at the principal amount thereof, or
such portion thereof, into that number of fully paid and non-assessable shares
(calculated as to each conversion to the nearest 1/100 of a share) of Class A
Common Stock obtained by dividing the principal of the Exchange Debenture or
portion thereof surrendered for conversion by the Conversion Price, determined
as hereinafter provided, in effect at the time of conversion.  If an Exchange
Debenture or portion thereof is called for redemption, such conversion right in
respect of the Exchange Debenture or portion thereof so called shall expire at
the close of business on the fifth Business Day preceding the Redemption Date
(except with respect to deemed conversions provided for in Section 2.6(i)),
unless the Company defaults in making the payment due upon redemption, in which
case such right of conversion shall be reinstated.

          The price at which shares of Class A Common Stock shall be delivered
upon conversion (herein called the "Conversion Price") shall be initially $67.44
per share of Class A Common Stock.  The Conversion Price shall be adjusted in
certain instances as provided in clause (d) below.

          (b) Exercise of Conversion Privilege.
              -------------------------------- 

          In order to exercise the conversion privilege, the Holder of any
Exchange Debenture to be converted shall surrender such Exchange Debenture duly
endorsed or assigned to the Company or in blank, at the Corporate Trust Office
or at any other office or agency of the Company maintained for that purpose
pursuant to Section 1002, accompanied by written notice to the Company at the
Corporate Trust Office or at any other office or agency of the Company
maintained in that purpose pursuant to Section 1002 that the Holder elects to
convert such Exchange Debenture or, if less than the entire principal amount
thereof is to be converted, the portion thereof to be converted.  Such notice
shall also state the name(s), together with address(es), in which the
certificate(s) for shares of Class A Common Stock shall be issued.

          Except as provided in the next sentence, Exchange Debentures
surrendered for conversion during the period from the close of business on any
Regular Record Date next preceding any Interest Payment Date to the opening of
business on such Interest Payment
<PAGE>
 
                                       7

Date shall be accompanied by payment in New York Clearing House funds or other
funds acceptable to the Company of an amount equal to the interest payable on
such Interest Payment Date on the principal amount of Exchange Debentures being
surrendered for conversion.  Subject to the provisions of Section 307 relating
to the payment of Defaulted Interest by the Company, the interest payment with
respect to an Exchange Debenture called for redemption on a Redemption Date
during the period from the fifth Business Day following any Regular Record Date
next preceding any Interest Payment Date to the fifth Business Day following
such Interest Payment Date shall be payable on such Interest Payment Date to the
Holder of such Exchange Debenture at the close of business on such Regular
Record Date notwithstanding the conversion of such Exchange Debenture after the
close of business on such Regular Record Date and prior to the opening of
business on such Interest Payment Date, and the Holder converting such Exchange
Debenture need not include a payment of such interest payment amount upon
surrender of such Exchange Debenture for conversion.  In the case of any
Exchange Debenture which is converted after any Regular Record Date and on or
prior to the next succeeding Interest Payment Date, interest whose Stated
Maturity is due on such Interest Payment Date shall be payable on such Interest
Payment Date notwithstanding such conversion, and such interest (whether or not
punctually paid or duly provided for) shall be paid to the Person in whose name
that Exchange Debenture (or one or more Predecessor Securities) is registered at
the close of business on such Regular Record Date.  In the case of any Exchange
Debenture which is converted on or after any Interest Payment Date, interest
whose Stated Maturity is due on such Interest Payment Date shall be payable on
such Interest Payment Date to the Holder of such Exchange Debenture on the
Regular Record Date relating to such Interest Payment Date.  Except as otherwise
expressly provided in the immediately preceding sentence in the case of any
Exchange Debenture which is converted, interest whose Stated Maturity is after
the date of conversion of such Exchange Debenture shall not be payable.

          Except as provided herein and subject to the foregoing, no payment or
adjustment shall be made upon any conversion on account of any interest accrued
on the Exchange Debentures surrendered for conversion or on account of any
dividends on the Class A Common Stock issued upon conversion.

          Exchange Debentures shall be deemed to have been converted immediately
prior to the close of business on the day of surrender of such Exchange
Debentures for conversion in accordance with the foregoing provisions, and at
such time the rights of the Holders of such Exchange Debentures as Holders shall
cease, and the Person or Persons entitled to receive the Class A Common Stock
issuable upon conversion shall be treated for all purposes as the record holder
or holders of such Class A Common Stock at such time.  As promptly as
practicable on or after the conversion date, the Company shall issue and shall
deliver to the Corporate Trust Office or at any other office or agency of the
Company mentioned pursuant to Section 1002 a certificate or certificates for the
number of full shares of Class A Common Stock issuable upon conversion, together
with payment in lieu of any fraction of a share, as provided in clause (c)
below.
<PAGE>
 
                                       8

          In the case of any Exchange Debenture which is converted in part only,
upon such conversion the Company shall execute and the Trustee shall
authenticate and deliver to the Holder thereof, at the expense of the Company, a
new Exchange Debenture or Exchange Debentures of authorized denominations in
aggregate principal amount equal to the unconverted portion of the principal
amount of such Exchange Debenture.

          (c)  Fractions of Shares.
               ------------------- 

          No fractional interest in a share of Class A Common Stock shall be
issued upon the conversion of Exchange Debentures.  If more than one Exchange
Debenture shall be surrendered for conversion at one time by the same Holder,
the number of full shares which shall be issuable upon conversion thereof shall
be computed on the basis of the aggregate principal amount of the Exchange
Debentures (or specified portions thereof) so surrendered.  Any fractional
interest in a share of Class A Common Stock resulting from conversion of any
Exchange Debenture (or specified portions thereof) shall be paid in cash
(computed to the nearest cent) based on the Closing Price of the Class A Common
Stock on the last Trading Day prior to the date on which such Exchange Debenture
is surrendered for conversion in the manner set forth above.

          (d) Adjustment of Conversion Price.
              ------------------------------ 

          The Conversion Price shall be adjusted from time to time as follows:

          (i)  In case the Company shall pay or make a dividend or other
distribution on any class of capital stock of the Company in Class A Common
Stock, the Conversion Price in effect at the opening of business on the day
following the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be reduced by multiplying such
Conversion Price by a fraction the numerator of which shall be the number of
shares of Class A Common Stock outstanding at the close of business on the date
fixed for such determination and the denominator of which shall be the sum of
such number of shares and the total number of shares constituting such dividend
or other distribution, such reduction to become effective immediately after the
opening of business on the day following the date fixed for such determination.
For the purposes of this clause (i), the number of shares of Class A Common
Stock at any time outstanding shall not include shares held in the treasury of
the Company.  The Company will not pay any dividend or make any distribution on
shares of Class A Common Stock held in the treasury of the Company.

          (ii)  In case the Company shall issue rights or warrants to all
holders of its Class A Common Stock entitling them to subscribe for, purchase or
acquire shares of Class A Common Stock at a price per share less than the
current market price per share (determined as provided in clause (vi) of this
Section) of the Class A Common Stock on the date fixed for the determination of
stockholders entitled to receive such rights or warrants, the Conversion Price
in effect at the opening of business on the day following the date fixed
<PAGE>
 
                                       9

for such determination shall be reduced by multiplying such Conversion Price by
a fraction the numerator of which shall be the number of shares of Class A
Common Stock outstanding at the close of business on the date fixed for such
determination plus the number of shares of Class A Common Stock which the
aggregate of the offering price of the total number of shares of Class A Common
Stock so offered for subscription, purchase or acquisition would purchase at
such current market price and the denominator of which shall be the number of
shares of Class A Common Stock outstanding at the close of business on the date
fixed for such determination plus the number of shares of Class A Common Stock
so offered for subscription, purchase or acquisition, such reduction to become
effective immediately after the opening of business on the day following the
date fixed for such determination.  For the purposes of this clause (ii), the
number of shares of Class A Common Stock at any time outstanding shall not
include shares held in the treasury of the Company.  The Company will not issue
any rights or warrants in respect of shares of Class A Common Stock held in the
treasury of the Company.

          (iii)  In case the outstanding shares of Class A Common Stock shall be
subdivided into a greater number of shares of Class A Common Stock, the
Conversion Price in effect at the opening of business on the day following the
day upon which such subdivision becomes effective shall be proportionately
reduced, and, conversely, in case the outstanding shares of Class A Common Stock
shall each be combined into a smaller number of shares of Class A Common Stock,
the Conversion Price in effect at the opening of business on the day following
the day upon which such combination becomes effective shall be proportionately
increased, such reduction or increase, as the case may be, to become effective
immediately after the opening of business on the day following the day upon
which such subdivision or combination becomes effective.

          (iv)  In case the Company shall, by dividend or otherwise, distribute
to all holders of its Class A Common Stock (a) evidences of its indebtedness
and/or (b) cash or other assets (excluding (x) any rights or warrants referred
to in clause (ii) above, (y) any dividend or distribution referred to in clause
(i) above, and (z) cash dividends or distributions from earnings unless the sum
of (1) all such cash dividends and distributions made within the preceding 12
months in respect of which no adjustment has been made and (2) any cash and the
fair market value of other consideration paid in respect of any repurchases of
Common Stock by the Company or any of its subsidiaries within the preceding 12
months in respect of which no adjustment has been made, exceeds 20% of the
Company's market capitalization (being the product of the then current market
price per share (determined as provided in subsection (vi) below) of the Class A
Common Stock times the aggregate number of shares of Class A Common Stock and
Class B Common Stock then outstanding) on the record date for such
distribution), then in each case, the Conversion Price in effect at the opening
of business on the day following the date fixed for the determination of holders
of Common Stock entitled to receive such distribution shall be adjusted by
multiplying such Conversion Price by a fraction of which the numerator shall be
the current market price per share (determined as provided in subsection (vi)
below) of the Class A Common Stock on such
<PAGE>
 
                                       10

date of determination (or, if earlier, on the date on which the Class A Common
Stock goes "ex-dividend" in respect of such distribution) less the then Fair
Market Value as determined by the Board of Directors (whose determination shall
be conclusive and shall be described in a statement filed with the Trustee) of
the portion of the other assets or evidences of indebtedness so distributed (and
for which an adjustment to the Conversion Price has not previously been made
pursuant to the terms of this Section 2.4) applicable to one share of Class A
Common Stock, and the denominator shall be such current market price per share
of the Class A Common Stock, such adjustment to become effective immediately
after the opening of business on the day following such date of determination.
The following transactions shall be excluded from the foregoing clauses (1) and
(2):  (i) any conversion of Class B Common Stock into Class A Common Stock, (ii)
repurchases of Common Stock issued under the Company's stock incentive programs,
and (iii) 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.

          (v)  The reclassification of Class A Common Stock into securities
including securities other than Class A Common Stock (other than any
reclassification upon a consolidation or merger to which clause (k) applies)
shall be deemed to involve (a) a distribution of such securities other than
Class A Common Stock to all holders of Class A Common Stock (and the effective
date of such reclassification shall be deemed to be "the date fixed for the
determination of holders of Common Stock entitled to receive such distribution"
within the meaning of clause (iv) of this Section), and (b) a subdivision or
combination, as the case may be, of the number of shares of Class A Common Stock
outstanding immediately prior to such reclassification into the number of shares
of Class A Common Stock outstanding immediately thereafter (and the effective
date of such reclassification shall be deemed to be "the day upon which such
subdivision becomes effective" or "the day upon which such combination becomes
effective", as the case may be, and "the day upon which such subdivision or
combination becomes effective" within the meaning of clause (iii) of this
Section).

          (vi)  For the purpose of any computation under clauses (ii) or (iv)
above, the current market price per share of Class A Common Stock on any day
shall be deemed to be the average of the Closing Prices for the 20 consecutive
Trading Days selected by the Board of Directors commencing no more than 30
Trading Days before and ending no later than the day before the day in question;
provided that, in the case of clause (iv), if the period between the date of the
public announcement of the dividend or distribution and the date for the
determination of holders of Class A Common Stock entitled to receive such
dividend or distribution (or, if earlier, the date on which the Class A Common
Stock goes "ex-dividend" in respect of such dividend or distribution) shall be
less than 20 Trading Days, the period shall be such lesser number of Trading
Days but, in any event, not less than five Trading Days.
<PAGE>
 
                                       11

          (vii)  No adjustment in the Conversion Price shall be required unless
such adjustment (plus any adjustments not previously made by reason of this
clause (vii)) would require an increase or decrease of a least 1% in such price;
provided, however, that any adjustments which by reason of this clause (vii) are
- --------  -------                                                               
not required to be made shall be carried forward and taken into account in any
subsequent adjustment and provided, further, that adjustments shall be required
and made in accordance with the provisions of this Section 2.4 (other than this
clause (vii)) not later than such time as may be required in order to preserve
the tax free nature of a distribution to the holders of shares of Class A Common
Stock.  Anything in this clause (vii) to the contrary notwithstanding, the
Company shall be entitled, at its option, to make such reductions in the
Conversion Price, in addition to those required by this clause (d), as it in its
discretion shall determine to be advisable in order that any stock dividend,
subdivision or combination of shares, distribution of capital stock, or rights
or warrants to purchase stock or securities, or distribution of evidences of
indebtedness or assets (other than cash dividends or distributions paid from
earnings) or other event shall be a tax free distribution for federal income tax
purposes.  All calculations under this clause (vii) shall be made to the nearest
cent.

          (e) Notice of Adjustments of Conversion Price.
              ----------------------------------------- 

          Whenever the Conversion Price is adjusted as herein provided, the
Company shall obtain a certificate of a firm of independent public accountants
setting forth the Conversion Price after such adjustment and setting forth a
brief statement of the facts requiring such adjustment and the manner of
computing same, which certificate shall constitute conclusive evidence, absent
manifest error, of the correctness of such adjustment.  Such certificate shall
forthwith be filed at each office or agency maintained for the purpose of
conversion of Exchange Debentures pursuant to Section 1002 and shall be mailed
by the Company to all Holders at their last addresses as they shall appear in
the Security Register.

          (f) Notice of Certain Corporate Action.
              ---------------------------------- 

          In case:

          (i)  the Company shall take any action that would cause an adjustment
     to the Conversion Price; or

          (ii)  of any consolidation, merger or share exchange to which the
     Company is a party and for which approval of any stockholders of the
     Company is required, or of the sale or transfer of all or substantially all
     of the assets of the Company; or

          (iii)  of the voluntary or involuntary dissolution, liquidation or
     winding-up of the Company;
<PAGE>
 
                                       12

then the Company shall cause to be filed at the Corporate Trust Office and each
other office or agency maintained for the purpose of conversion of Exchange
Debentures pursuant to Section 1002 and shall cause to be mailed to all Holders
at their last addresses as they shall appear in the Security Register, at least
15 days prior to the applicable record or effective date hereinafter specified,
a notice stating (x) the date on which a record is to be taken for the purpose
of such dividend, distribution, rights or warrants, or, if a record is not to be
taken, the date as of which the holders of Class A Common Stock of record to be
entitled to such dividend, distribution, rights or warrants are to be
determined, or (y) the date on which such consolidation, merger, share exchange,
sale, transfer, dissolution, liquidation or winding-up is expected to become
effective, and the date as of which it is expected that holders of Class A
Common Stock of record shall be entitled to exchange their shares of Class A
Common Stock for securities, cash or other property deliverable upon such
consolidation, merger, share exchange, sale, transfer, dissolution, liquidation
or winding-up.  Neither the failure to give such notice nor any defect therein
shall affect the legality or validity of the proceedings described in subclauses
(i) through (iii) of this clause (f).  If at the time the Trustee shall not be
the conversion agent, a copy of such notice shall also forthwith be filed by the
Company with the Trustee.

          (g) Company to Reserve Class A Common Stock.
              --------------------------------------- 

          Upon and following the issuance of the Exchange Debentures, the
Company shall at all times reserve and keep available out of its authorized but
unissued Class A Common Stock, for the purpose of effecting the conversion of
Exchange Debentures, the full number of shares of Class A Common Stock then
issuable upon the conversion of all outstanding Exchange Debentures not
theretofore converted.

          (h)  Taxes on Conversions.
               -------------------- 

          The Company will pay any and all documentary stamp or similar issue or
transfer taxes that may be payable in respect of the issue or delivery of shares
of Class A Common Stock on conversion of Exchange Debentures pursuant hereto.
The Company shall not, however, be required to pay any tax which may be payable
in respect of any transfer involved in the issue and delivery of shares of Class
A Common Stock in a name other than that of the Holder of the Exchange Debenture
or Exchange Debentures to be converted, and no such issue or delivery shall be
made unless and until the Person requesting such issue has paid to the Company
the amount of any such tax, or has established to the satisfaction of the
Company that such tax has been paid.

          (i) Covenant as to Class A Common Stock.
              ----------------------------------- 

          The Company covenants that all shares of Class A Common Stock which
may be issued upon conversion of Exchange Debentures will, upon issue, be duly
and validly
<PAGE>
 
                                       13

issued, fully paid and non-assessable, free of all liens and charges and not
subject to any preemptive right.

          (j) Cancellation of Converted Exchange Debentures.
              --------------------------------------------- 

          All Exchange Debentures delivered for conversion shall be delivered to
the Trustee to be canceled by or at the direction of the Trustee, which shall
dispose of the same as provided in Section 309.

          (k) Provisions in Case of Consolidation, Merger or Sale of Assets.
              ------------------------------------------------------------- 

          In case of (i) any consolidation of the Company with, or merger of the
Company into, any other Person, (ii) any merger of another Person 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) or (iii) any sale or transfer of all or substantially all of the assets
of the Company, the Person formed by such consolidation or resulting from such
merger or which acquires such assets, as the case may be, shall execute and
deliver to the Trustee a supplemental indenture providing that the Holder of
each security then outstanding shall have the right thereafter, during the
period such Exchange Debenture shall be convertible as specified in clause (a)
above, to convert such Exchange Debenture 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
into which such Exchange Debenture might have been converted immediately prior
to such consolidation, merger, sale or transfer, assuming such holder of Class A
Common Stock is not a person with which the Company consolidated or into which
the Company merged or which merged into the Company or to which such sale or
transfer was made, as the case may be (a "Constituent Person"), or an Affiliate
of a Constituent Person and failed to exercise his rights of election, if any,
as to the kind or amount of securities, cash or other property receivable upon
such consolidation, merger, sale or transfer (provided that if the kind or
amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer is not the same for each share of Class
A Common Stock held immediately prior to such consolidation, merger, sale or
transfer by other than a Constituent Person or an Affiliate thereof and in
respect of which such rights of election shall not have been exercised ("non-
electing share"), then for the purpose of this clause (k) the kind and amount of
securities, cash and other property receivable upon such consolidation, merger,
sale or transfer by each non-electing share shall be deemed to be the kind and
amount so receivable per share by a plurality of the non-electing shares).  Such
supplemental indenture shall provide for adjustments which, for events
subsequent to the effective date of such supplemental indenture, shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Article.  The above provisions of this clause (k) shall similarly apply to
successive consolidations, mergers, sales or transfers.
<PAGE>
 
                                       14

          (l)  Trustee's Disclaimer.
               -------------------- 

          The Trustee has no duty to determine when an adjustment under this
Article should be made, how it should be made or what it should be.  The Trustee
makes no representation as to the validity or value of any securities or assets
issued upon conversion of securities.  The Trustee shall not be responsible for
the Company's failure to comply with this Article.  Each conversion agent other
than the Company shall have the same protection under this Section as the
Trustee.

          SECTION 2.5.  Redemption.
                        ---------- 

          The Exchange Debentures may be redeemed at the option of the Company,
in whole or in part, at any time on or after November 1, 1999, on not less than
30 nor more than 60 days' prior notice at the redemption prices (expressed as
percentages of principal amount) set forth below, together with accrued and
unpaid interest, if any, to the date of redemption, if redeemed during the 12-
month period beginning on November 1 of the years indicated (subject to the
right of Holders of record on relevant record dates to receive interest due on
an Interest Payment Date):

                        the Holder.
                        ----------

          (a)   Upon the occurrence of any Change of Control of the Company
occurring prior to the Maturity of the Exchange Debentures, each Holder shall
have the right, at such Holder's option, to require the Company to purchase, on
the Change of Control Purchase Date referred to below, all or any part of such
Holder's Exchange Debentures for cash at a price equal to 100% of the principal
amount thereof, together with accrued and unpaid interest thereon to such date
(the "Change of Control Purchase Price").  Notwithstanding the foregoing, a
holder of Exchange Debentures will not have the option to require the Company to
purchase all or any part of the Exchange Debentures if either (i) the Closing
Price of the Class A Common Stock for five of the ten Trading Days immediately
preceding the date of the Change of Control equals or exceeds 105% of the then
prevailing Conversion Price or (ii) the consideration paid for the Class A
Common Stock in a transaction constituting the Change of Control consists of
cash, Marketable Stock or a combination of cash and Marketable Stock and as a
result of such Change of Control, the Class A Common Stock becomes convertible
into cash and/or Marketable Stock, and the
<PAGE>
 
                                       15

aggregate fair market value per share of such consideration is at least 105% of
the then prevailing Conversion Price in effect immediately before the closing of
such transaction.

          (b)  Within 30 Business Days after any such Change of Control, the
Company shall give to the Trustee and to each Holder of the Exchange Debentures
(and to beneficial owners as required by applicable law, including, without
limitation, Rule 13e-4 under the Exchange Act) in the manner provided in Section
106 of the Indenture notice regarding such Change of Control setting forth the
following:

          (i) that a Change of Control has occurred and that such Holder has the
     right to require the Company to purchase such Holder's Exchange Debentures
     at the Change of Control Purchase Price;

          (ii) the circumstances and relevant facts regarding such Change of
     Control (including but not limited to information with respect to pro forma
                                                                       ---------
     historical income, cash flow and capitalization after giving effect to such
     Change of Control);

          (iii)  the last date on which the Holder's right to have its Exchange
     Debentures purchased may be exercised (the "Expiration Date"), which shall
     be, subject to any contrary requirements of applicable law, not less than
     30 days or more than 60 days after the date of such notice;

          (iv) the Change of Control Purchase Price;

          (v) a settlement date (the "Change of Control Purchase Date") for the
     purchase of Exchange Debentures, which shall be within five Business Days
     after the Expiration Date;

          (vi) the name and address of the Trustee and of any other office or
     agency maintained for the purpose of the surrender of Exchange Debentures
     for purchase;

          (vii)  the procedures that a Holder must follow in order to have its
     Exchange Debentures purchased, including a copy of the form of Change of
     Control Purchase Notice referred to in Section 2.6(c) hereof;

          (viii)  that any Exchange Debenture not tendered will continue to
     accrue interest; and

          (ix) that, unless the Company defaults in payment of the Change of
     Control Purchase Price, any Exchange Debentures accepted for payment of the
     Change of Control Purchase Price pursuant to a Change of Control Notice (as
     defined in Section 2.6(d) below) shall cease to accrue interest after the
     Change of Control Purchase Date.
<PAGE>
 
                                       16

          (c)  Holders electing to have Exchange Debentures purchased must
deliver written notice (a "Change of Control Purchase Notice") to the Trustee or
to any other office or agency maintained for such purpose, of the exercise of
such right prior to the close of business on the Change of Control Purchase
Date.   The Change of Control Purchase Notice must state:

          (i) the certificate numbers of the Exchange Debentures to be delivered
     by the Holder thereof for purchase by the Company;

          (ii) the portion of the principal amount of Exchange Debentures to be
     purchased, which portion must be $1,000 or an integral multiple thereof;
     and

          (iii)  that such Exchange Debentures are to be purchased by the
     Company on the Change of Control Purchase Date pursuant to the applicable
     provisions of the Exchange Debentures.

          (d) Upon receipt by the Trustee of any Change of Control Purchase
Notice specified in Section 2.6(c) hereof, the Trustee shall furnish to the
Company, in writing or by facsimile, a copy of such notice before the close of
business on the next Business Day following the date of receipt of such notice
from the Holder.  Upon receipt by the Company of such notice, the Holder of the
Exchange Debenture in respect of which such Change of Control Purchase Notice
was given shall (unless such Change of Control Purchase Notice is withdrawn as
specified in the following paragraph) thereafter be entitled to receive solely
the Change of Control Purchase Price with respect to such Exchange Debenture.
Such Change of Control Purchase Price shall be due and payable as of the Change
of Control Purchase Date and shall be paid to such Holder promptly following the
later of (x) the Change of Control Purchase Date (provided the conditions in
Section 2.6(c) hereof, as applicable, have been satisfied) and (y) the date of
delivery of such Exchange Debenture to the Trustee or to the office or agency
referred to in Section 1002 of the Indenture by the Holder thereof in the manner
required by Section 2.6(c) hereof.  Exchange Debentures in respect of which a
Change of Control Purchase Notice has been given by the Holder thereof may not
be converted into shares of Class A Common Stock on or after the date of the
delivery of such Change of Control Purchase Notice, unless such Change of
Control Purchase Notice has first been validly withdrawn as specified in the
following paragraph.

          Any Change of Control Purchase Notice may be withdrawn by the Holder
by a written notice of withdrawal delivered to the Trustee or to any other
office or agency maintained for such purpose on or prior to the close of
business on the Expiration Date.  Such notice of withdrawal shall state:

          (i) the principal amount of Exchange Debentures and the certificate
     numbers of the Exchange Debentures as to which the withdrawal notice
     relates; and
<PAGE>
 
                                       17

          (ii) the principal amount of Exchange Debentures, if any, which
     remains subject to the original Change of Control Purchase Notice.

          There shall be no purchase of any Exchange Debentures pursuant to this
Section 2.6 if there has occurred (prior to, on or after, as the case may be,
the giving, by the Holders of such Exchange Debentures, of the required Change
of Control Purchase Notice) and is continuing an Event of Default (other than a
default in the payment of the Change of Control Purchase Price with respect to
such Exchange Debentures).

          (e) Prior to the Change of Control Purchase Date but in no event more
than ten days prior to such date, the Company shall deposit with the Trustee
(or, if the Company or a Subsidiary or an Affiliate of either of them is acting
as paying agent, shall segregate and hold in trust as provided in Section 1003
of the Indenture) an amount of cash in immediately available funds or
securities, if expressly permitted hereunder, sufficient to pay the aggregate
Change of Control Purchase Price of all the Exchange Debentures or portions
thereof which are to be purchased.  Upon any such deposit, interest shall cease
to accrue on such Exchange Debentures (or portions thereof) on and after the
Change of Control Purchase Date, and the Holders thereof shall have no other
rights as such (other than the right to receive the Change of Control Purchase
Price, upon surrender of such Exchange Debentures).

          (f) Payment of the Change of Control Purchase Price for an Exchange
Debenture for which a Change of Control Purchase Notice has been delivered and
not withdrawn is conditioned upon delivery of such Exchange Debenture (together
with necessary endorsements) to the Trustee or to any other office or agency
maintained for such purpose, at any time (whether prior to, on or after the
Change of Control Purchase Date) after delivery of such Change of Control
Purchase Notice.  Payment of the Change of Control Purchase Price for such
Exchange Debenture will be made promptly following the later of the Change of
Control Purchase Date or the time of delivery of such Exchange Debenture.

          (g) The Company shall comply with the tender offer rules under the
Exchange Act which may then be applicable and, if required, will file Schedule
13E-4 or any other schedule required thereunder in connection with any offer by
the Company to purchase Exchange Debentures at the option of Holders upon a
Change of Control.

          (h) The Trustee shall return to the Company any cash, together with
interest or dividends, if any, thereon (subject to the provisions of Section 605
of the Indenture) held by it for the payment of the Change of Control Purchase
Price of the Exchange Debentures that remain unclaimed as provided in Section
1003 of the Indenture; provided, however, that to the extent that the aggregate
                       --------  -------                                       
amount of cash deposited by the Company pursuant to Section 2.6(e) hereof
exceeds the aggregate Change of Control Purchase Price of the Exchange
Debentures or portions thereof to be purchased, then promptly after the Change
of Control Purchase Date, the Trustee shall return any such excess
<PAGE>
 
                                       18

to the Company together with interest or dividends, if any, thereon (subject to
the provision of Section 605 of the Indenture).

          (i) In connection with any redemption of Exchange Debentures, the
Company may arrange for the purchase and conversion of any such Exchange
Debentures by an agreement with one or more investment bankers or other
purchasers to purchase such Exchange Debentures by paying to the Holders of
Exchange Debentures, or to the Trustee in trust for such Holders, on or before
the close of business on the day prior to the Redemption Date, an amount, in
cash, not less than the redemption price payable by the Company on redemption of
such Exchange Debentures, together with the amount of accrued and unpaid
interest thereon to the date fixed for redemption.  Notwithstanding anything to
the contrary contained herein, the obligation of the Company to pay the
redemption price of such Exchange Debentures, together with the amount of
accrued and unpaid interest thereon to the Redemption Date, shall be satisfied
and discharged to the extent such amount is so paid by such purchasers.
Pursuant to such an agreement, any such Exchange Debentures tendered by the
Holder for redemption or not duly surrendered for conversion by such Holder
shall be deemed acquired by such purchasers from such Holder and
(notwithstanding anything to the contrary contained in Section 2.4 hereof)
surrendered by such purchasers for conversion, all as of immediately prior to
the close of business on the day prior to the Redemption Date, subject to
payment of the above as aforesaid.

          The Trustee shall be under no obligation to ascertain the occurrence
of a Change of Control or to give notice with respect thereto.  The Trustee may
conclusively assume, in the absence of written notice to the contrary from the
Company, that no Change of Control has occurred.

                                                      November 7, 1995



Cablevision Systems Corporation,
   One Media Crossways,
      Woodbury, New York 11797.

Dear Sirs:

     In connection with the registration under the Securities Act of 1933 (the
"Act") of (i) 1,200,000 shares of 8 1/2% Series I Cumulative Convertible
Exchangeable Preferred Stock (the "Preferred Stock") of Cablevision Systems
Corporation, a Delaware corporation (the "Company"), (ii) 12,000,000 of the
Company's depositary shares (the "Depositary Shares") evidenced by depositary
receipts (the "Depositary Receipts") to be issued against deposit of the
Preferred Stock pursuant to the Deposit Agreement, dated as of November 7, 1995
(the "Deposit Agreement"), among the Company, Harris Trust and Savings Bank, as
Depositary (the "Depositary"), and the holders from time to time of Depositary
Receipts issued thereunder, each such Depositary Share representing a one-tenth
interest in a share of the Preferred Stock, and (iii) the shares of Class A
Common
<PAGE>
 
Cablevision Systems Corporation                                          -2-


Stock, par value $.01 per share, of the Company initially issuable upon
conversion of the Depositary Shares (the "Class A Common Stock"), as the case
may be, we, as your counsel, have examined such corporate records, certificates
and other documents, and such questions of law, as we have considered necessary
or appropriate for the purposes of this opinion.  Upon the basis of such
examination, we advise you that, in our opinion:

          (1)  The Preferred Stock has been duly authorized, and, upon payment
     therefor and delivery to the Underwriters thereof pursuant to the
     Underwriting Agreement, dated November 1, 1995, between the Company and
     Bear Stearns & Co. Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated
     and Morgan Stanley & Co. Incorporated (the "Underwriters") will be validly
     issued, fully paid and nonassessable.

          (2) The Preferred Stock will be convertible into Class A Common Stock
     of the Company in accordance with the Company's Certificate of
     Incorporation, and the shares of Class A Common Stock initially issuable
     upon conversion of the Preferred Stock have been duly authorized and
     reserved for issuance upon such conversion and, when issued upon such
     conversion, will be validly issued, fully paid and nonassessable.
<PAGE>
 
Cablevision Systems Corporation                                          -3-


          (3) Assuming that the Deposit Agreement has been duly authorized,
     executed and delivered by the Depositary, upon due execution and delivery
     of the Depositary Receipts by the Depositary against the deposit by the
     Company of the Preferred Stock pursuant to the Deposit Agreement and as
     contemplated in the Registration Statement, the Depositary Shares will be
     validly issued.

          The foregoing opinion is limited to the Federal laws of the United
States, the laws of the State of New York and the General Corporation Law of the
State of Delaware, and we are expressing no opinion as to the effect of the laws
of any other jurisdiction nor with respect to any Federal or state laws relating
to communications or individuals, companies or businesses engaged in the
communications business, including the provision of cable television services.

          We have relied as to certain matters on information obtained from
public officials, officers of the Company and other sources believed by us to be
responsible.

          We hereby consent to the filing of this opinion as an exhibit to the
Company's Current Report on Form 8-K, and to the reference to us under the
headings "Validity of Depositary Shares and Class A Common Stock" in the

     In connection with the registration under the Securities Act of 1933 (the
"Act") of $300,000,000 principal amount of 9 1/4% Senior Subordinated Notes due
2005 (the "Securities") of Cablevision Systems Corporation, a Delaware
corporation (the "Company"), we, as your counsel, have examined such corporate
records, certificates and other documents, and such questions of law, as we have
considered necessary or appropriate for the purposes of this opinion.

     Upon the basis of such examination, we advise you that, in our opinion,
upon (a) the due execution and authentication of the Securities in accordance
with the Indenture between the Company and The Bank of New York, as Trustee,
dated as of November 1, 1995, and (b) payment therefor and delivery to the
Underwriters thereof pursuant to the Purchase Agreement, dated November 2, 1995,
between

the Company and Merrill Lynch, Pierce, Fenner & Smith Incorporated, Bear Stearns
& Co. Inc., Morgan Stanley & Co. Incorporated and Toronto Dominion (USA) Inc.
(the "Underwriters"), the Securities will constitute valid and legally binding
obligations of the Company, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors' rights and to general equity principles.

     The foregoing opinion is limited to the Federal laws of the United States,
the laws of the State of New York and the General Corporation Law of the State
of Delaware, and we are expressing no opinion as to the effect of the laws of
any other jurisdiction nor with respect to any Federal or state laws relating to
communications or individuals, companies or businesses engaged in the
communications business, including the provision of cable television services.

     We have relied as to certain matters on information obtained from public
officials, officers of the Company and other sources believed by us to be
responsible, and we have assumed that the Indenture has been duly authorized,
executed and delivered by the Trustee

thereunder, an assumption which we have not independently verified.

     We hereby consent to the filing of this opinion as an exhibit to the
Company's Current Report on Form 8-K, and to the reference to us under the
headings "Validity of Notes" in the Prospectus Supplement, dated November 2,
1995, relating to the Securities and "Validity of the Securities" in the

category of persons whose consent is required under Section 7 of the Act.

share of the Preferred Stock, and (iii) the shares of Class A Common Stock, par

          Cablevision Systems Corporation, a Delaware corporation (herein called
the "Company", which term includes any successor entity under the Indenture
hereinafter referred to), for value received, hereby promises to pay to Cede &
Co. or registered assigns the principal sum of                DOLLARS on
November 1, 2005, at the office or agency of the Company referred to below, and
to pay interest thereon on May 1, 1996 and semiannually thereafter, on November
1 and May 1 in each year, from November 7, 1995 or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, at the rate
of 9 1/4% per annum, until the principal hereof is paid or duly provided for,
and (to the extent lawful) to pay on demand interest on any overdue interest at
the rate borne by the Securities from the date of the Interest Payment Date on
which such overdue interest becomes payable to the date payment of such interest
has been made or duly provided for.  The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in
such Indenture, be paid to the Person in whose name this Security (or one or
more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest, which shall be the April 15 or October 15
(whether or not a Business Day), as the case may be, next preceding such
Interest Payment Date.  Any such interest not so punctually paid or duly
provided for, and interest on such defaulted interest at the interest rate borne
by the Securities, to the extent lawful, shall forthwith cease to be payable to
the Holder on such Regular Record Date, and may be paid to the Person in whose
name this Security (or one or more Predecessor Securities) is registered at the
close of business on a Special Record Date for the payment of such Defaulted
Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Securities not less than 10 days prior to such Special Record Date, or may be
paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange on which the Securities may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in said Indenture.  Payment of the principal of (and premium, if any)
and interest on this Security will be made at the office or agency of the
Company maintained for that purpose in The City of New York, or at such other
office or agency of the Company as may be maintained for such purpose, in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts; provided, however, that
payment of interest may be made at the option of the Company by check mailed to
the address of the Person entitled thereto as such address shall appear on the
Security Register.

                         [FORM OF REVERSE OF SECURITY]


          This Security is one of a duly authorized issue of securities of the
Company designated as its 9 1/4% Senior Subordinated Notes due 2005 (herein
called the "Securities"), limited (except as otherwise provided in the Indenture
referred to below) in aggregate principal amount to $300,000,000, which may be
issued in one or more series under an indenture (herein called the "Indenture")
dated as of November 1, 1995, between the Company and The Bank of New York,
trustee (herein called the "Trustee", which term includes any successor trustee
under the Indenture with respect to the series of which this Security is a
part), to which Indenture and all indentures supplemental thereto reference is
hereby made for a statement of the respective rights, limitations of rights,
duties, obligations and immunities thereunder of the Company, the Trustee, the
holders of the Senior Indebtedness and the Holders of the Securities, and of the
terms upon which the Securities are, and are to be, authenticated and delivered.

          The Securities are subject to redemption upon not less than 30 nor
more than 60 days' notice by first-class mail, at any time on or after November
1, 2000, as a whole or in part, at the election of the Company, at a Redemption
Price equal to the percentage of the principal amount set forth below if
redeemed during the 12-month period beginning November 1 of the years indicated:

               Year                       Redemption Price
               ----                       ----------------

               2000                        104.625%
               2001                        103.100
               2002                        101.500

and thereafter at 100% of the principal amount, together in the case of any such
redemption with accrued interest, if any, to the Redemption Date, all as
provided in the Indenture.

          In the case of any redemption of Securities, interest installments
whose Stated Maturity is on or prior to the Redemption Date will be payable to
the Holders of such Securities, or one or more Predecessor Securities, of record
at the close of business on the relevant Record Date referred to on the face
hereof.  Securities (or portions thereof) for whose redemption and payment
provision is made in accordance with the Indenture shall cease to bear interest
from and after the Redemption Date.

          In the event of redemption of this Security in part only, a new
Security or Securities for the unredeemed portion hereof shall be issued in the
name of the Holder hereof upon the cancellation hereof.
<PAGE>
 
                                       6

          If an Event of Default shall occur and be continuing, the principal of
all the Securities may be declared due and payable in the manner and with the
effect provided in the Indenture.

          The Indenture contains provisions for defeasance at any time of (a)
the entire indebtedness of the Company on this Security and (b) certain
restrictive covenants and the related Defaults and Events of Default, upon
compliance by the Company with certain conditions set forth therein, which
provisions apply to this Security.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of each series affected under the
Indenture at any time by the Company and the Trustee with the consent of the
Holders of a majority in aggregate principal amount of the Securities of such
series at the time Outstanding.  The Indenture also contains provisions
permitting the Holders of specified percentages in aggregate principal amount of
the Securities of each series at the time Outstanding, on behalf of the Holders
of all the Securities of such series, to waive compliance by the Company with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences.  Any such consent or waiver by or on behalf of
the Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof whether
or not notation of such consent or waiver is made upon this Security.

          The Securities are subordinated in right of payment, in the manner and
to the extent set forth in the Indenture, to the prior payment in full of all
Senior Indebtedness of the Company whether outstanding on the date of the
Indenture or thereafter created, incurred, assumed or guaranteed.  Each
Securityholder by his acceptance hereof agrees to be bound by such provisions
and authorizes and expressly directs the Trustee, on his behalf, to take such
action as may be necessary or appropriate to effectuate the subordination
provided for in the Indenture and appoints the Trustee his attorney-in-fact for
such purpose.

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Security at the times, place, and rate, and in the coin or
currency, herein prescribed.

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable on the Security
Register of the Company, upon surrender of this Security for registration of
transfer at the office or agency of the Company maintained for such purpose in
The City of New York, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
<PAGE>
 
                                       7

thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

          The Securities are issuable only in registered form, without coupons
in denominations of $1,000 and any integral multiple thereof.  As provided in
the Indenture and subject to certain limitations therein set forth, the
Securities are exchangeable for a like aggregate principal amount of Securities
of a different authorized denomination, as requested by the Holder surrendering
the same.

          No service charge shall be made for any registration of transfer or
exchange or redemption of Securities, but the Company may require payment of a
sum sufficient to pay all documentary, stamp or similar issue or transfer taxes
or other governmental charges payable in connection with any registration of
transfer or exchange.

          Prior to the time of due presentment of this Security for registration
of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Security is registered as the
owner hereof for all purposes, whether or not this Security be overdue, and
neither the Company, the Trustee nor any agent shall be affected by notice to
the contrary.

          All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

          The following abbreviations, when used in the inscription on the face
of this Security, shall be construed as though they were written out in full
