ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS.

     On March 4, 1998 (the "Closing Date"), subsidiaries of 
Tele-Communications, Inc. ("TCI") transferred to CSC Parent Corporation, a 
Delaware corporation (to be known immediately after the closing as 
Cablevision Systems Corporation) ("New CSC"), cable television systems owned 
and operated by TCI serving approximately 830,000 subscribers, as of January 
31, 1998.  The systems transferred were located in Union, Mercer, Monmouth, 
Somerest, Middlesex, Morris, Sussex, Bergen and Passaic counties in New 
Jersey and in Rockland, Suffolk and Westchester counties in New York (the 
"NJ/NY Systems").  In addition to its ownership interest in the NJ/NY 
Systems, New CSC will hold all of the common stock of the former Cablevision 
Systems Corporation (to be known immediately after closing as CSC Holdings, 
Inc.).  The NJ/NY Systems were transferred either directly by the transfer of 
the assets of such cable systems or indirectly by the transfer of partnership 
interests or capital stock in the entities owning such cable systems, in 
exchange for 12,235,543 shares (prior to adjustment for a stock dividend) of 
Class A common stock, par value $0.01 per share, of New CSC ("New CSC Class A 
Common Stock") representing an approximate 33% common equity ownership 
interest in New CSC and assumption by New CSC of certain liabilities, 
including approximately $669 million in debt, relating to the cable 
television systems transferred by TCI to New CSC.  Such exchange was made 
pursuant to the terms of the Contribution and Merger Agreement dated as of 
June 6, 1997, as amended and restated by the Amended and Restated 
Contribution and Merger Agreement (the "Contribution and Merger Agreement") 
dated as of June 6, 1997, by and among TCI Communications, Inc., a subsidiary 
of TCI, New CSC, and certain affiliates of New CSC (the "Transaction").  The 
amount of the consideration payable in the Transaction was based on 
arm's-length negotiations between the parties.

<PAGE>

     On the Closing Date, TCI and its subsidiaries holding the New CSC Class 
A Common Stock issued in the Transaction (collectively, the "Investor"), New 
CSC and certain holders (the "Class B Stockholders") of Class B common stock 
of New CSC ("New CSC Class B Common Stock", and together with the New CSC 
Class A Common Stock, "New CSC Common Stock") entered into a Stockholders 
Agreement (the "New CSC Stockholders Agreement") providing, among other 
things, for:  (i) limits on the Investor's ability to acquire New CSC Class A 
Common Stock other than pursuant to the Transaction or in other limited 
circumstances, if, following such acquisition, the Investor would own 
beneficially 10% or more of the New CSC Class A Common Stock in excess of the 
shares of New CSC Class A Common Stock issued to the Investor in the 
Transaction; (ii) limitations on the Investor's ability to transfer the 
shares of New CSC Class A Common Stock; (iii) consultation rights among New 
CSC, TCI, and the Class B Stockholders regarding sales of New CSC as a whole 
or significant assets of New CSC, certain sales of New CSC Class A Common 
Stock owned by the Investor and certain sales of New CSC Class B Common Stock 
owned by the Class B Stockholders; (iv) certain tag-along rights of the 
Investor and drag-along rights of the Class B Stockholders upon certain sales 
of New CSC Common Stock by the Class B Stockholders; (v) preemptive rights 
for the Investor on new issuances of New CSC Common Stock so that the 
Investor may maintain beneficial ownership of the percentage of the 
outstanding New CSC Common Stock owned by the Investor immediately prior to 
such new issuance, with certain limited exceptions; (vi) the Investor's right 
to designate two directors ("Investor Directors") for so long as certain 
ownership of New CSC Class A Common Stock is maintained by the Investor; 
(vii) the right of the Investor Directors to membership on a committee of the 
Board of Directors of New CSC to approve certain transactions with Class B 
Stockholders and their family members that will give such Investor Directors 
a veto over such transactions; (viii) the Investor's agreement to vote in 
proportion with the public holders of New CSC Class A Common Stock for the 
election of the directors of New CSC which the New CSC Class A Common Stock 
is entitled to elect and any increase in authorized shares; (ix) agreement by 
New CSC not to effect acquisition transactions that would cause the debt to 
cash flow ratio of New CSC (calculated as described in the New CSC 
Stockholders Agreement) to exceed a specified ratio (initially 8.0 : 1.0, and 
declining to 7.5 : 1.0 after December 31, 1999); and (x) certain registration 
rights under the Securities Act of 1933, as amended, for shares of New CSC 
Class A Common Stock owned by the Investor.  John C. Malone and Leo J. 
Hindery, Jr., executive officers and directors of TCI, have been designated 
as the Investor Directors of New CSC.

                              September 30, 1997
                                  (unaudited)


(1)  On March 4, 1998 (the "Closing Date"), subsidiaries of Tele-
     Communications, Inc. ("TCI") transferred to CSC Parent Corporation, a
     Delaware corporation (to be known immediately after the closing as
     Cablevision Systems Corporation) ("New CSC"), cable television systems
     owned and operated by TCI serving approximately 830,000 subscribers, as of
     January 31, 1998.  The systems transferred were located in Union, Mercer,
     Monmouth, Somerest, Middlesex, Morris, Sussex, Bergen and Passaic counties
     in New Jersey and in Rockland, Suffolk and Westchester counties in New
     York (the "NJ/NY Systems").  In addition to its ownership interest in the
     NJ/NY Systems, New CSC will hold all of the common stock of the former
     Cablevision Systems Corporation (to be known immediately after the closing
     as CSC Holdings, Inc.).  The NJ/NY Systems were transferred either
     directly by the transfer of the assets of such cable systems or indirectly
     by the transfer of partnership interests or capital stock in the entities
     owning such cable systems, in exchange for 12,235,543 shares (prior to
     adjustment for a stock dividend) of Class A common stock, par value $0.01 
     per share, of New CSC ("New CSC Class A Common Stock") representing an 
     approximate 33% common equity ownership interest in New CSC and assumption 
     by New CSC of certain liabilities, including approximately $669 million in 
     debt, relating to the cable television systems transferred by TCI to New 
     CSC.  Such exchange was made pursuant to the terms of the Contribution and 
     Merger Agreement dated as of June 6, 1997, as amended and restated by the 
     Amended and Restated Contribution and Merger Agreement (the "Contribution 
     and Merger Agreement") dated as of June 6, 1997, by and among TCI 
     Communications, Inc., a subsidiary of TCI, New CSC, and certain affiliates 
     of New CSC (the "Transaction").  The amount of the consideration payable in
     the Transaction was based on arm's-length negotiations between the parties.

(2)  Effective February 6, 1998, TCI issued stock dividends to holders of Tele-
     Communications, Inc. Series A and Series B Liberty Media Group Common
     Stock ("Liberty Group Stock") (the "1998 Liberty Stock Dividend") and Tele-
     Communications, Inc. Series A and Series B TCI Ventures Group Common Stock
     ("TCI Ventures Group Stock") (the "Ventures Stock Dividend").  The 1998
     Liberty Stock Dividend consisted of one share of Liberty Group Stock for
     every two shares of Liberty Group Stock owned.  The Ventures Stock
     Dividend consisted of one share of TCI Venture Group Stock for every one
     share of TCI Ventures Group Stock owned.  The 1998 Liberty Stock Dividend
     and the Ventures Stock Dividend have been treated as stock splits, and
     accordingly, all share and per share amounts have been restated to reflect
     the 1998 Liberty Stock Dividend and the Ventures Stock Dividend.

(3)  Represents the receipt of 12,235,543 shares (prior to adjustment for a 
     stock dividend) of New CSC Class A Common Stock valued at approximately 
     $1,161 million, based on the closing per share price of New CSC's Class A 
     Common Stock of $94.875 on the Closing Date.

(4)  Represents the estimated gain from the contribution to New CSC of the
     NJ/NY Systems.  The estimated gain represents the excess of the fair value
     of New CSC Class A Common Stock received (approximately $1,161 million)
     over the net assets of the NJ/NY Systems (approximately $677 million), net
     of the estimated deferred tax effect of the Transaction.

(5)  Represents TCI's proportionate share of New CSC's pro forma losses for the
     applicable period including the amortization, over an estimated 10 year
     life, of the difference between the fair value of consideration received
     and TCI's proportionate share of New CSC's net deficiency.

(6)  Represents the estimated tax effect of the pro forma adjustments, assuming
     an effective tax rate of 40%.

(7)  Represents pro forma loss per share assuming 670.0 million and 664.8
     million weighted average shares of TCI Group common stock were outstanding
     during the nine months ended September 30, 1997 and the year ended
     December 31, 1996, respectively.  Such amounts represent the weighted
     average shares disclosed in TCI Group's historical financial statements.

prepare, or cause to be prepared, and deliver to the Company a Closing Date 
consolidated balance sheet relating to both the Asset Contributed Systems and

the consolidated assets and liabilities of the Contributed Entities and 
Acquired Assets and Assumed 

                                       -9-

<PAGE>

Liabilities and the Net Adjusted Working Capital as of the 
Closing Date, shall be prepared in accordance with the principles and methods 
applied to the Proxy Financial Statements and shall be accompanied by 
reasonably detailed information supporting the numbers set forth therein.  
For this purpose, in no event will purchase accounting adjustments relating 
to the Contribution Closing be made to the Closing Balance Sheet.  For the 
purpose of this Agreement:  (i) "CURRENT ASSETS" means the aggregate amount 
of cash, marketable securities, deposits, active subscriber accounts 
receivables that are no more than 90 days past due (based on date of invoice) 
for those subscribers who have been subscribers and have paid for at least 
one entire billing cycle and prepaid expenses and advertising sales accounts 
receivables for all such receivables, net of reserves for doubtful accounts, 
each as reflected as current assets on a balance sheet prepared in accordance 
with generally accepted accounting principles ("GAAP") applied in a manner 
consistent with that applied in the preparation of the Proxy Financial 
Statements, except that the Fibertech Cash and any Excluded Assets shall not 
be included; (ii) "LIABILITIES" means the aggregate amount of any and all 
liabilities (current and long term and whether or not contingent) reflected 
as liabilities on a balance sheet prepared in accordance with GAAP applied in 
a manner consistent with that applied in preparation of the Proxy Financial 
Statements, except that the Assumed Company Debt, the Surety Liabilities, any 
Excluded Liabilities and any other liability or obligation terminated 
pursuant to Section 6.15(a) without any liability or obligation to any 
Contributed Entity or any Asset Contributed System after the Contribution 
Closing shall not be included; and (iii) "NET ADJUSTED WORKING CAPITAL" 
equals (x) the Current Assets minus (y) the sum of the Liabilities and the 
amount by which the total of the Surety Liabilities exceeds $10,000,000.

          (b)  The Company and the Company's accountants shall, within 30 
days after the delivery by Parent of the Closing Balance Sheet and the 
information required to be delivered with the Closing Balance Sheet, complete 
their review of the Net Adjusted Working Capital derived from the Closing 
Balance Sheet.  In the event that the Company determines that the Net 
Adjusted Working Capital has not been determined on the basis set forth in 
Section 3.4(a) and this Section 3.4(b), the Company shall inform Parent in 
writing (the "COMPANY'S OBJECTION"), setting forth a specific description of 
the basis of the Company's Objection and the adjustments to the Net Adjusted 
Working Capital that the Company believes should be made, on or before the 
last day of such 30-day period.  Parent shall then have 20 days to review and 
respond to the Company's Objection.  If Parent

                                       -10-

<PAGE>

and the Company are unable to resolve all of their disagreements with respect 
to the determination of the foregoing items within 10 days following the 
completion of Parent's review of the Company's Objection, they shall refer 
their remaining differences to KPMG Peat Marwick (or its successor) or 
another internationally recognized firm of independent public accountants as 
to which the Company and Parent mutually agree (the "CPA FIRM"), who shall, 
acting as experts and not as arbitrators, determine on the basis of the 
standards set forth in Section 3.4(a) and this Section 3.4(b), and only with 
respect to the remaining differences so submitted, whether and to what 
extent, if any, the Net Adjusted Working Capital, as derived from the Closing 
Balance Sheet, requires adjustment.  The parties shall instruct the CPA Firm 
to deliver its written determination to Parent and the Company no later than 
the twentieth day after the remaining differences underlying the Company's 
Objection are referred to the CPA Firm.  The CPA Firm's determination shall 
be conclusive and binding upon Parent and the Company and shall not be 
subject to appeal.  The fees and disbursements of the CPA Firm shall be paid 
by the Person whose estimate of Net Adjusted Working Capital differs the most 
from that ultimately determined by the CPA Firm.  Parent and the Company 
shall (and Parent shall cause the Contributed Entities to) make readily 
available to the CPA Firm all relevant books and records and any work papers 
(including those of the parties' respective accountants) relating to the 
Financial Statements and Closing Balance Sheet and all other items reasonably 
requested by the CPA Firm.  The "ADJUSTED CLOSING BALANCE SHEET" shall be (i) 
the Closing Balance Sheet in the event that (x) the Company's Objection is 
not delivered to Parent during the 30-day period specified above or (y) the 
Company and Parent so agree, (ii) the Closing Balance Sheet, adjusted in 
accordance with the Company's Objection, in the event that Parent does not 
respond to the Company's Objection within the 20-day period following receipt 
by Parent of the Company's Objection, or (iii) the Closing Balance Sheet, as 
adjusted by either (x) the agreement of the Company and Parent or (y) the CPA 
Firm.  In the event that the adjustment of the Closing Balance Sheet pursuant 
to this Section 3.4(b) discloses that it is appropriate to include an item in 
the calculation of Net Adjusted Working Capital that had been omitted from 
the Closing Balance Sheet or to omit an item in the calculation of Net 
Adjusted Working Capital that had been included in the Closing Balance Sheet, 
Parent shall prepare a revised Closing Balance Sheet including or omitting 
such item, as the case may be, as at the date thereof.

                                       -11-

<PAGE>

          (c)  Within five business days following issuance of the Adjusted 
Closing Balance Sheet, the payments payable pursuant to this Section 3.4(c) 
shall be paid by wire transfer of immediately available funds to a bank 
account designated by Parent or the Company, as the case may be, together 
with interest thereon (at the prime rate of interest of Citibank N.A. in 
effect on the Closing Date) from and including the Closing Date and up to but 
not including the date of payment.  If the Net Adjusted Working Capital is 
more than zero, Parent will make a payment to the Company in the amount by 
which the Net Adjusted Working Capital exceeds zero, as derived from the 
Adjusted Closing Balance Sheet.  If the Net Adjusted Working Capital is less 
than zero, the Company will make a payment to Parent in the amount by which 
the Net Adjusted Working Capital is less than zero, as derived from the 
Adjusted Closing Balance Sheet.  Any adjustment payment in respect of Net 
Adjusted Working Capital required to be made by Parent to the Company will be 
subject to set-off to the extent of any failure by the Company to comply with 
Section 6.15(a), Section 6.17(a) or Section 6.17(d).  In the event that the 
aforementioned set-off is insufficient to fully compensate Parent due to any 
failure by the Company to comply with Section 6.15(a), Section 6.17(a) or 
Section 6.17(d), the Company shall make a payment to Parent in the amount 
equal to such insufficient amount. 

          3.5. ANTIDILUTION ADJUSTMENTS.  If, between the date of this 
Agreement and the Contribution Closing, CSC or Parent issues from time to 
time any Shares or shares of Parent Common Stock other than in full or 
partial satisfaction of the obligations ("ISSUE EXCEPTIONS") that are 
described on Schedule 3.5 then, upon any such issue, the number of Parent 
Class A Shares comprising the Stock Consideration shall be adjusted (to be 
either increased or decreased) in accordance with the following formula:

                    X' = 1,419,322,988
                         -------------
                              C'

where:

     X'   =    the adjusted aggregate number of Parent Class A Shares comprising
               the Stock Consideration immediately following such issue (rounded
               to the nearest whole share);

                                       -12-

<PAGE>

     O    =    the number of Shares or shares of Parent Common Stock outstanding
               immediately prior to such issue; 

     I    =    the aggregate number of Shares or shares of Parent Common Stock
               to be issued in such issue;

     C    =    initially $116, and following any antidilution adjustment the C'
               from the immediately preceding antidilution calculation;

     P    =    the price per Share of the Shares or shares of Parent Common
               Stock to be issued in such issue calculated by reference, as the
               case may be, to (i) the aggregate amount of the principal of,
               interest on, fees and any other amount in respect of the
               indebtedness that is paid, redeemed or satisfied in such issue or
               (ii) the aggregate amount of the liquidation value of, dividends
               on, and any other amount in respect of the Preferred Shares that
               is paid, redeemed or satisfied in such issue; and

     C'   =    V + V';
               -----
               O + I


     V    =    C x O; and

     V'   =    P x I.

          3.6.  FAILURE TO RECEIVE THIRD PARTY CONSENTS. Notwithstanding 
anything to the contrary in this Agreement, this Agreement shall not 
constitute an agreement to assign or transfer any approval, instrument or 
Contract, or any claim, right or benefit arising thereunder or arising 
therefrom, if an assignment or transfer or an attempt to make such an 
assignment or transfer without the consent of a third party would be void or 
constitute a breach or violation thereof or affect adversely any of the 
rights or obligations of Parent thereunder; and any transfer or assignment to 
Parent of any interest under any such approval, instrument or Contract that 
requires the consent of a third party shall be made subject to such consent 
or approval being obtained.  In the event that any such consent or approval 
is not obtained on or prior to the Closing Date, the Company (i) shall use 
its commercially reasonable efforts to obtain any such consent or approval 
after the 

                                       -13-

<PAGE>

Closing Date until such time as such consent or approval has been obtained 
and (ii) shall cooperate with Parent in any lawful arrangement designed to 
provide Parent or its Subsidiaries, as the case may be, with the full 
economic benefits under any such approval, instrument or Contract, including 
performance by the Company or its Affiliates, as the case may be, as an 
agent, or in a similar role, for Parent or its Subsidiaries, as the case may 
be, PROVIDED that Parent shall undertake to pay or satisfy (or cause the 
payment or satisfaction of) the corresponding liabilities for the enjoyment 
or such benefit only to the extent Parent would have been responsible 
therefor hereunder if such consent or approval had been obtained prior to the 
Closing Date.  No party hereto shall be required to pay any material 
payments, agree to any material restrictions on its or any of its affiliates' 
business or commence or pursue any litigation in order to comply with this 
Section 3.6. Nothing in this Section 3.6 shall be deemed a waiver or 
modification by Parent of its right to receive an effective assignment and 
transfer of all of the Acquired Assets, nor shall this Section 3.6 be deemed 
to constitute an agreement to exclude from the Acquired Assets any approvals, 
instruments or Contributed Contracts described in this Section or to require 
the obtaining of any consent or approval not otherwise required to be 
obtained under the terms of this Agreement.

SHARE"), of Parent (in the case of CSC Class B Shares) (the Parent Class A 
Shares and the Parent Class B Shares are together referred to herein as the 
"PARENT COMMON STOCK").  At the Effective Time, all Shares shall no longer be 
outstanding and shall be canceled and retired and shall cease to exist, and 
each certificate (a "CERTIFICATE") formerly representing any of such Shares 
(other than Excluded Shares) shall thereafter be deemed for all purposes to 
represent the number of shares of Parent Common Stock into which such Shares 
were converted pursuant to this Section 4.1.

          (b)  CANCELLATION OF SHARES AND PARENT COMMON STOCK.  Each Share 
issued and outstanding immediately prior to the Effective Time and owned by 
any of the Parent Companies (other than Shares that are in each case owned on 
behalf of third parties) and each share of Parent Common Stock owned by any

restated certificate of incorporation of CSC, as amended.

          4.2. TRANSFERS.  After the Effective Time, if Certificates are

DGCL, no appraisal rights shall be available to holders of Shares or 
Preferred Shares in connection with the Merger.

          4.4. ADJUSTMENTS TO PREVENT DILUTION.  In the event that CSC changes
the number of Shares or securities convertible or exchangeable into or
exercisable for Shares, or Parent changes the number of shares of Parent Common

of Parent Common Stock, issued and outstanding prior to the Effective Time as a
result of a reclassification, stock split (including a reverse split), stock
dividend or stock distribution, recapitalization, subdivision, issuer tender or
exchange offer, or other similar transaction, the Merger Consideration and the

of the Stock Consideration, any adjustment made pursuant to Section 3.5.


                                      ARTICLE V

                            Representations and Warranties

          5.1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  Except as set
forth in the corresponding sections or subsections of the disclosure letter
delivered to Parent by the Company on or prior to entering into this Agreement
(the "COMPANY DISCLOSURE LETTER"), the Company hereby represents and warrants to
CSC, Parent and Merger Sub that:

          (a)  ORGANIZATION, GOOD STANDING AND QUALIFICATION.  Each of the
Contributed Entities, the Contributed System Entities and the Company is a
corporation duly organized, validly existing and in good standing under the laws
of its respective jurisdiction of organization and has all requisite corporate
power and authority to own and operate its properties and assets and to carry on
its business as presently conducted and is qualified to do business and is in
good standing as a foreign corporation in each jurisdiction where the ownership
or operation of its properties or conduct of its business requires such
qualification, except where the failure to be so qualified or in good standing,
when taken together with all other such failures, is not reasonably likely to
have a Contributed Systems Material Adverse Effect.  The Company has made
available to Parent a complete and correct copy of the Company's and the
Contributed Entities' respective certificates of incorporation and by-laws or
comparable governing instruments, each as amended to date.  The 

                                       -16-

<PAGE>

Company's and the Contributed Entities' respective certificates of 
incorporation and by-laws or comparable governing instruments so delivered 
are in full force and effect. TCI owns directly all of the outstanding Common 
Stock of the Company, and the Company is TCI's principal cable property 
holding company.  Section 5.1(a) of the Company Disclosure Letter contains a 
correct and complete list of each jurisdiction where each of the Contributed 
Subsidiaries is and each of the Contributed System Entities is or, if Future 
Contributed System Entities, will be as of the Contribution Closing organized 
and qualified to do business.

          As used in this Agreement, the term (i) "SUBSIDIARY" means, with 
respect to the Company, any Contributed Entity, CSC, Parent or Merger Sub, as 
the case may be, any entity, whether incorporated or unincorporated, of which 
at least a majority of the securities or ownership interests having by their 
terms ordinary voting power to elect a majority of the board of directors or 
other persons performing similar functions is directly or indirectly owned or 
controlled by such party or by one or more of its respective Subsidiaries or 
by such party and any one or more of its respective Subsidiaries (it being 
agreed that until the Effective Time, Parent shall be deemed a Subsidiary of 
CSC for all purposes hereunder) and (ii) "CONTRIBUTED SYSTEMS MATERIAL 
ADVERSE EFFECT" means a material adverse effect on the financial condition, 
properties, business or results of operations of all of the Contributed 
Systems, taken as a whole, excluding any such effects proximately caused by 
CSC or Parent or any of their respective Subsidiaries.

          (b)  CAPITAL STRUCTURE; ACQUIRED ASSETS; INDEBTEDNESS.  (i)  The 
authorized and outstanding capital stock of each Contributed Entity is set 
forth in Section 5.1(b) of the Company Disclosure Letter.  All of the 
outstanding shares of capital stock in each of the Contributed Entities have 
been duly authorized and are validly issued, fully paid and nonassessable and 
are owned beneficially and of record by a direct or indirect  Subsidiary of 
the Company, free and clear of any Lien.  Except as required to consummate 
the Company Restructuring, there are no preemptive or other outstanding 
rights, options, warrants, conversion rights, stock appreciation rights, 
redemption rights, repurchase rights, agreements, arrangements or commitments 
to issue or sell any shares of capital stock or other securities of the 
Contributed Entities or any securities or obligations convertible or 
exchangeable into or exercisable for, or giving any Person a right to 
subscribe for or acquire, any securities of the 

                                       -17-

<PAGE>

Contributed Entities, and no securities or obligations evidencing such rights 
are authorized, issued or outstanding.  No Contributed Entity has any shares 
of capital stock reserved for issuance.  No Contributed Entity has 
outstanding any bonds, debentures, notes or other obligations the holders of 
which have the right to vote (or to convert into or be exercised or exchanged 
for securities having the right to vote) ("VOTING DEBT") with the 
stockholders of any Contributed Entity on any matter.  There are no voting 
trusts, proxies, or other commitments or understandings, restrictions or 
arrangements of any kind in favor of any Person with respect to the voting 
of, or the right to participate in dividends or other earnings on, any 
securities or other ownership interests of any Contributed Entity.  Each of 
the Contributed System Entities is or, if a Future Contributed System Entity, 
will be as of the Contribution Closing a Subsidiary of the Company.  All of 
the Asset Contributed Systems are owned and operated within, and all of the 
Acquired Assets and Assumed Liabilities are contained within, the Contributed 
System Entities.

          (ii)  The Acquired Assets, taken as a whole, constitute and will 
constitute all the properties, assets, privileges, rights, and interests of 
the Company and its Subsidiaries relating to, used in or held for use in 
connection with or otherwise required to carry on the business of the Asset 
Contributed Systems as of the date hereof and as of immediately after the 
Contribution Closing, except to the extent that Excluded Assets may relate 
to, be used in or held for use in connection with or otherwise be required to 
carry on such business.

          (iii)  Section 5.1(b) of the Company Disclosure Letter, which shall 
be supplemented on the third business day before the Closing Date in 
accordance with Section 6.17(e), sets forth all of the outstanding 
Indebtedness of each of the Contributed System Entities (including the Future 
Contributed System Entities as of the Contribution Closing) and each of the 
Contributed Entities, the maturity thereof and the interest rate thereon, 
except for the Assumed Company Debt, which is set forth to the best 
approximation by the Company as of the date hereof and shall be set forth in 
exact amounts on the third business day prior to the Closing Date.  As used 
in this Agreement, the term "INDEBTEDNESS" means, without duplication, any 
liability, whether or not contingent, (i) in respect of borrowed money or 
evidenced by bonds, notes, debentures or similar instruments or letters of 
credit (or reimbursement agreements in respect thereto), but excluding 
reimbursement obligations under any surety bond and reimbursement obligations 
and letters of credit and other forms of surety 

                                       -18-

<PAGE>

for cable franchises and other operating agreements, (ii) representing the 
balance deferred and unpaid of the purchase price of any property, except any 
such balance that constitutes a trade payable arising in the ordinary course 
of business, (iii) any obligation of a Person to pay rent or other amounts 
under a lease with respect to any property (whether real, personal or mixed) 
acquired or leased by such Person and used in its business that is required 
to be accounted for as a liability on the balance sheet of such Person in 
accordance with GAAP, and the amount of such obligation constituting 
Indebtedness shall be the amount so required to be accounted for as a 
liability, (iv) under any other agreement related to the fixing or exchanging 
of interest rates on any Indebtedness described above, such as an interest 
swap, cap or collar agreement, or (v) guarantees of items of other Persons 
which would be included within this definition of Indebtedness for such other 
Persons (whether or not the guarantee would appear on a balance sheet of such 
other Person).  The aggregate amount of liabilities, whether or not 
contingent, in respect of reimbursement obligations and letters of credit and 
other forms of surety for cable franchises and other operating agreements, 
excluding reimbursement obligations under any surety bonds (collectively, the 
"SURETY LIABILITIES") does not exceed $10,000,000.

          (c)  CORPORATE AUTHORITY; APPROVAL.  (i)  Each of the Company and TCI
has (and as of the Contribution Closing each Contributed System Entity will
have) all requisite corporate power and authority and has taken (or, in the case
of the Contributed System Entities, as of the Contribution Closing will have
taken) all corporate action necessary in order to execute, deliver and perform
its obligations under this Agreement and to consummate the Contribution (it
being understood that, for the purposes of this Agreement, consummation of the
Contribution shall include consummation of the transactions contemplated by the
Company Restructuring).  This Agreement is a valid and binding agreement of the
Company and TCI enforceable against each of them 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 (the "BANKRUPTCY AND EQUITY
EXCEPTION").

          (ii) The board of directors of each of the Company and TCI has
approved this Agreement and the Contribution.  No approval of the stockholders
of the Company or of TCI is required for the effectiveness, validity or
enforceability of this Agreement or the transactions contemplated hereby.

          (d)  GOVERNMENTAL FILINGS; NO VIOLATIONS.  (i) Other than the 
filings and/or notices under the Hart-Scott-Rodino Antitrust Improvements Act 
of 1976, as amended (the "HSR ACT"), and except as set forth in Section 
5.1(d) of the Company Disclosure Letter, no notices, reports or other filings 
are required to be made by the Company or any of its Subsidiaries with, nor 
are any consents, registrations, approvals, permits or authorizations 
required to be obtained by the Company or any of its Subsidiaries from, any 
governmental, regulatory or self-regulatory (including a sports league) 
authority, agency, commission, body or other governmental entity 
("GOVERNMENTAL ENTITY"), in connection with the execution and delivery of 
this Agreement by the Company and the consummation by the Company of the 
Contribution and the performance of its other obligations hereunder, except 
those that the failure to make or obtain are not, individually or in the 
aggregate, reasonably likely to have a Contributed Systems Material Adverse 
Effect or prevent, materially delay or materially impair the ability of the 
Company to consummate the Contribution and the other transactions 
contemplated by this Agreement.

          (ii)  The execution, delivery and performance of this Agreement by 
the Company do not, and the consummation by the Company of the Contribution 
and the performance of its other obligations hereunder will not, constitute 
or result in (A) a breach or violation of, or a default under, the respective 
certificates of incorporation or by-laws of the Contributed System Entities, 
the Contributed Entities or the Company or the comparable governing 
instruments of any of the Contributed System Entities or any of the 
Contributed Entities, (B) a breach of or violation of or a default under, or 
the acceleration of any obligations of or the creation of a Lien on the 
assets of the Contributed Entities, the Company or any of its Subsidiaries 
(with or without notice, lapse of time or both) pursuant to, any agreement, 
lease, license, franchise, permit, concession, contract, note, mortgage, 
indenture, arrangement or other obligation ("CONTRACTS") binding upon the 
Contributed Entities, the Company or any of its Subsidiaries or any Law or 
governmental or non-governmental permit or license to which the Contributed 
Entities, the Company or any of its Subsidiaries is subject or (C) any change 
in the rights or obligations of any party under any of the Contracts, except, 
in the case of clause (B) or (C) above, for any breach, violation, default, 
acceleration, creation or change that, individually or in the aggregate, is 
not reasonably likely to have a Contributed Systems Material Adverse Effect 
or prevent, materially delay or materially impair the ability of the Company 
to consummate the transactions contemplated by this Agreement.  Section 
5.1(d) of the Company Disclosure 

                                       -20-

<PAGE>

Letter sets forth a correct and complete list of Contracts of the Contributed 
Entities, the Company and its Subsidiaries pursuant to which consents or 
waivers are or may be required prior to consummation of the Contribution and 
the other transactions contemplated by this Agreement (whether or not subject 
to the material adverse effect or materiality exception set forth with 
respect to clauses (B) and (C) above), other than any such Contract (x) the 
amount that could be paid or received thereunder after the Audit Date does 
not exceed $100,000 per annum and $250,000 in the aggregate or (y) that is 
terminable by any of the Contributed System Entities or by any of the 
Contributed Entities without penalty on less than 60 days' notice.

          (e)  FINANCIAL STATEMENTS.  The Company has delivered to Parent and 
CSC complete and correct copies of each of the financial statements listed in 
Section 5.1(e) of the Company Disclosure Letter (the "FINANCIAL STATEMENTS"). 
The Financial Statements fairly present, in all material respects, the 
financial position of each of the Contributed Systems as of the respective 
date indicated and the financial position and results of operations, as the 
case may be, of each of the Contributed Systems for the periods set forth 
therein, in each case in accordance with GAAP consistently applied during the 
periods involved, except for the omission of statements of retained earnings, 
changes in cash flows and financial positions and except for the omission of 
notes and normal year-end adjustments.  The Proxy Financial Statements 
(including the related notes and schedules) to be delivered to CSC by the 
Company will fairly present, in all material respects, the consolidated 
financial position of the Contributed Systems as of the respective dates 
indicated and the consolidated financial position and results of operations, 
retained earnings, changes in financial position and cash flows, as the case 
may be, of the Contributed Systems for the periods set forth therein 
(subject, in the case of unaudited statements) to notes and normal year-end 
audit adjustments that will not individually or in the aggregate be material 
in amount or effect, in each case in accordance with GAAP consistently 
applied during the periods involved, except as may be noted therein.  The 
financial positions and results of operations reflected in the Proxy 
Financial Statements, when delivered, will not differ in any material respect 
from that reflected in the Financial Statements for the same periods involved 
(other than any purchase accounting adjustments and accruals for Taxes which 
were not reflected in the Financial Statements).

          (f)  ABSENCE OF CERTAIN CHANGES.  Since March 31, 1997 (the "AUDIT
DATE"): (i) the Company, the Contributed 

                                      -21-

<PAGE>

System Entities and the Contributed Entities have conducted their respective 
businesses relating to the Contributed Systems only in, and have not engaged 
in any material transaction other than according to, the ordinary and usual 
course of such businesses; and (ii) there has not been (I) any change in the 
financial condition, properties, business or results of operations of any of 
the Contributed Entities or the Contributed Systems or any event or 
development or combination of events or developments that, individually or in 
the aggregate, has had or is reasonably likely to have a Contributed Systems 
Material Adverse Effect (it being acknowledged and agreed that, for the 
purposes of this Agreement, knowledge or awareness of the Company shall 
include the knowledge or awareness of the Company, of the Contributed 
Entities and of any of the Contributed System Entities); PROVIDED, HOWEVER, 
that any such effect resulting from any change (x) in law, rule, or 
regulation or generally accepted accounting principles or interpretations 
thereof that applies to both CSC and the Contributed Systems or (y) in 
economic or business conditions generally or in the cable industry 
specifically shall not be considered when determining if a Contributed 
Systems Material Adverse Effect has occurred; (II) any material damage, 
destruction or other casualty loss with respect to any material asset or 
property owned, leased or otherwise used by the Company or any of its 
Subsidiaries with respect to the Contributed Systems, whether or not covered 
by insurance; (III) except as required to consummate the Company 
Restructuring, any declaration, setting aside or payment of any dividend or 
other distribution in respect of the capital stock of any of the Contributed 
System Entities or any of the Contributed Entities, except for cash dividends 
(excluding any dividend of any Fibertech Cash) or other dividends or 
distributions on its capital stock set forth in Section 5.1(f) of the Company 
Disclosure Letter; or (IV) any change in accounting principles, practices or 
methods used by the Contributed Entities or used with respect to the 
Contributed Systems.  Since the Audit Date, there has not been any material 
increase in the compensation payable or that could become payable by the 
Contributed Entities or the Contributed System Entities to officers or key 
employees of the Contributed Systems other than periodic or merit increases 
consistent with past practice or bonus payments that will not be the 
responsibility of or require any payment by Parent or any of its Subsidiaries 
(including, after the Contribution Closing, the Contributed Entities) or any 
amendment of any of the Compensation and Benefit Plans or the adoption of any 
new benefit plan or arrangement.

          (g)  LITIGATION AND LIABILITIES.  Except as set forth in Section
5.1(g) of the Company Disclosure Letter, 

                                       -22-

<PAGE>

there are no (i) civil, criminal or administrative actions, suits, claims, 
hearings, investigations or proceedings pending or, to the knowledge of the 
Company, threatened against any of the Contributed Entities or Contributed 
System Entities or against any of their respective "AFFILIATES" (as defined 
in Rule 12b-2 under the Exchange Act) relating directly or indirectly to any 
of the Contributed Entities or the Contributed Systems or their respective 
businesses or (ii) obligations or liabilities, whether or not accrued, 
contingent or otherwise and whether or not required to be disclosed, 
including those relating to matters involving any Environmental Law, or any 
other facts or circumstances of which the Company has knowledge that could 
result in any claims against, or obligations or liabilities of any of the 
Contributed Entities or Contributed Systems except, in the case of either 
clause (i) or (ii) above, for those that are not, individually or in the 
aggregate, reasonably likely to have a Contributed Systems Material Adverse 
Effect or prevent or materially burden or materially impair the ability of 
the Company to consummate the Contribution and the other transactions 
contemplated by this Agreement.

          (h)  EMPLOYEE BENEFITS.  (i) A copy of each bonus, deferred 
compensation, pension, retirement, profit-sharing, thrift, savings, employee 
stock ownership, stock bonus, stock purchase, restricted stock, stock option, 
employment, termination, severance, compensation, medical, health or other 
plan, agreement, policy or arrangement that covers current or former 
employees or directors of the Contributed Entities or of the Company or its 
Subsidiaries relating to the Contributed Systems and is in effect on the date 
hereof, other than "multiemployer plans" within the meaning of Section 3(37) 
of the Employee Retirement Income Security Act of 1974, as amended ("ERISA") 
(such plans, agreements, policies and arrangements, the "COMPENSATION AND 
BENEFIT PLANS"), and any trust agreement or insurance contract forming a part 
of such Compensation and Benefit Plans has been made available to Parent 
prior to the date hereof.  The Compensation and Benefit Plans are listed in 
Section 5.1(h) of the Company Disclosure Letter and any "change of control" 
or similar provisions therein are specifically identified in Section 5.1(h) 
of the Company Disclosure Letter to the extent that there would be any 
liability to or payment required by Parent or any of its Subsidiaries 
(including after the Contribution Closing, the Contributed Entities) 
thereunder.

          (ii)  All Compensation and Benefit Plans are in substantial compliance
with all applicable Laws, including the Code and ERISA.  Each Compensation and
Benefit Plan that 

                                       -23-

<PAGE>

is an "employee pension benefit plan" within the meaning of Section 3(2) of 
ERISA (a "PENSION PLAN") and that is intended to be qualified under Section 
401(a) of the Code has received a favorable determination letter from the 
Internal Revenue Service (the "IRS") with respect to "TRA" (as defined in 
Section 1 of Rev. Proc. 93-39), and the Company is not aware of any 
circumstances likely to result in revocation of any such favorable 
determination letter.  There is no pending or, to the knowledge of the 
Company, threatened material litigation relating to the Compensation and 
Benefit Plans.  Neither the Company nor any of its Subsidiaries has engaged 
in a transaction with respect to any Compensation and Benefit Plan that, 
assuming the taxable period of such transaction expired as of the date 
hereof, would subject any of the Contributed Entities to or otherwise cause 
the Contributed Systems to incur a material tax or penalty imposed by either 
Section 4975 of the Code or Section 502 of ERISA.

          (iii)  As of the date hereof, no liability under Subtitle C or D of 
Title IV of ERISA has been or is expected to be incurred by any of the 
Contributed Entities or of the Contributed Systems with respect to any 
ongoing, frozen or terminated "single-employer plan", within the meaning of 
Section 4001(a)(15) of ERISA, currently or formerly maintained by any of 
them, or the single-employer plan of any entity which is considered one 
employer with the Company under Section 4001 of ERISA or Section 414 of the 
Code (an "ERISA AFFILIATE"). The Contributed Entities and, with respect to 
the Contributed Systems, the Contributed System Entities have not incurred 
and do not expect to incur any withdrawal liability with respect to a 
multiemployer plan under Subtitle E to Title IV of ERISA.  No notice of a 
"reportable event", within the meaning of Section 4043 of ERISA for which the 
30-day reporting requirement has not been waived, has been required to be 
filed for any Pension Plan or by any ERISA Affiliate of the Contributed 
Entities or, with respect to the Contributed Systems, the Contributed System 
Entities within the 12-month period ending on the date hereof or will be 
required to be filed in connection with the transactions contemplated by this 
Agreement.

          (iv)  All contributions required to be made under the terms of any 
Compensation and Benefit Plan as of the date hereof have been timely made or 
have been reflected on the most recent Financial Statements.  Neither any 
Pension Plan nor any single-employer plan of an ERISA Affiliate of the 
Contributed Entities or, with respect to the Contributed Systems, the 
Contributed System Entities or the Company or its Subsidiaries has an 
"accumulated funding deficiency" (whether or not waived) within the meaning 
of Section 412 of 

                                       -24-

<PAGE>

the Code or Section 302 of ERISA.  None of the Contributed Entities or, with 
respect to the Contributed Systems, the Contributed System Entities has 
provided, or is required to provide, security to any Pension Plan or to any 
single-employer plan of an ERISA Affiliate of the Contributed Entities or, 
with respect to the Contributed Systems, the Contributed System Entities 
pursuant to Section 401(a)(29) of the Code.

          (v)  Under each Pension Plan which is a single-employer plan, as of 
the last day of the most recent plan year ended prior to the date hereof, the 
actuarially determined present value of all "benefit liabilities", within the 
meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the 
actuarial assumptions contained in the Pension Plan's most recent actuarial 
valuation), did not exceed the then current value of the assets of such 
Pension Plan, and there has been no material change in the financial 
condition of such Pension Plan since the last day of the most recent plan 
year.  The withdrawal liability of the Contributed Entities or, with respect 
to the Contributed Systems, the Contributed System Entities under each 
Compensation and Benefit Plan that is a multiemployer plan, determined as if 
a "complete withdrawal" within the meaning of Section 4203 of ERISA had 
occurred as of the date hereof, does not exceed $100,000.

          (vi)  None of the Contributed Entities or, with respect to the 
Contributed Systems, the Contributed System Entities has any obligations for 
retiree health and life benefits under any Compensation and Benefit Plan, 
except as set forth in the Company Disclosure Letter.  The Contributed 
Entities and, with respect to the Contributed Systems, the Contributed System 
Entities may amend or terminate any such plan under the terms of such plan at 
any time without incurring any material liability thereunder.

          (vii)  Except as expressly contemplated by Section 6.11(c), the 
consummation of the Contribution and the other transactions contemplated by 
this Agreement will not (x) entitle any current or former employees or 
directors ("EMPLOYEES") of the Contributed Entities or, with respect to the 
Contributed Systems, the Contributed System Entities to severance pay, (y) 
accelerate the time of payment or vesting or trigger any payment of 
compensation or benefits under, increase the amount payable or trigger any 
other material obligation pursuant to, any of the Compensation and Benefit 
Plans or (z) result, in any material respect, in any breach or violation of, 
or a default under, any of the Compensation and Benefit Plans.

          (i)  COMPLIANCE WITH LAWS; PERMITS.  The businesses of each of the 
Contributed Systems Entities and the  Contributed Entities have not been, and 
are not being, conducted in violation of any federal, state, local or foreign 
law, statute, ordinance, rule, regulation, judgment, order, injunction, 
decree, arbitration award, agency requirement, franchise, license or permit 
of any Governmental Entity (collectively, "LAWS"), except for violations or 
possible violations that, individually or in the aggregate, are not 
reasonably likely to have a Contributed Systems Material Adverse Effect or 
prevent or materially burden or materially impair the ability of the Company 
to consummate the Contribution and the other transactions contemplated by 
this Agreement.  No investigation or review by any Governmental Entity with 
respect to any of the Contributed Entities or the Contributed Systems is 
pending or, to the knowledge of the Company, threatened, nor has any 
Governmental Entity indicated an intention to conduct such investigation or 
review except any investigations or reviews that are not, individually or in 
the aggregate, reasonably likely to have a Contributed Systems Material 
Adverse Effect or prevent or materially burden or materially impair the 
ability of the Company to consummate the Contribution and the other 
transactions contemplated by this Agreement.  To the knowledge of the 
Company, no material change is required in any of the Contributed Systems' 
processes, properties or procedures in connection with any such Laws, and 
none of the Company, the Contributed Entities or the Contributed Systems has 
received any notice or communication of any noncompliance with any such Laws 
that has not been cured as of the date hereof except for such noncompliance 
that is not, individually or in the aggregate, reasonably likely to have a 
Contributed Systems Material Adverse Effect or prevent or materially burden 
or materially impair the ability of the Company to consummate the 
Contribution and the other transactions contemplated by this Agreement.  Each 
of the Contributed Entities and the Contributed Systems has all permits, 
licenses, franchises, variances, exemptions, orders and other governmental 
authorizations, consents and approvals necessary to conduct the businesses of 
its respective Contributed Systems as presently conducted, except those the 
absence of which are not, individually or in the aggregate, reasonably likely 
to have a Contributed Systems Material Adverse Effect or prevent or 
materially burden or materially impair the ability of the Company to 
consummate the Contribution and the other transactions contemplated by this 
Agreement.

          (j)  ENVIRONMENTAL MATTERS.  Except as set forth in Section 5.1(j) 
of the Company Disclosure Letter, and for

Contributed System Entities  with respect to the Asset Contributed Systems or

Entities; (iv) none of the Contributed System Entities with respect to the 
Asset Contributed Systems or the Contributed Entities is or has been subject 
to liability for any Hazardous Substance disposal or contamination on any 
third party property; (v) none of the Contributed System Entities with 
respect to the Asset Contributed Systems or the Contributed Entities has been 
associated with any release or threat of release of any Hazardous Substance; 
(vi) none of the Company or any of its Subsidiaries has received any notice, 
demand, letter, claim or request for information indicating that any of the 
Contributed System Entities with respect to the Asset Contributed Systems or 
the Contributed Entities may be in violation of or liable under any 
Environmental Law; (vii) none of the Contributed System Entities with respect 
to the Asset Contributed Systems or the Contributed Entities is or has been 
subject to any orders, decrees, injunctions or other arrangements with any 
Governmental Entity, or is subject to any indemnity or other agreement with 
any third party, regarding compliance or liability under any Environmental 
Law or relating to Hazardous Substances; (viii) there are no circumstances or 
conditions involving any of the Contributed System Entities with respect to 
the Asset Contributed Systems or the Contributed Entities that could 
reasonably be expected to result in any claims, liability, investigations, 
costs or restrictions on the ownership, use, or transfer of any property of 
any of the Contributed System Entities with respect to the Asset Contributed 
Systems or the Contributed Entities pursuant to any Environmental Law; (ix) 
none of the properties of any of the Contributed System Entities with respect

of the Contributed System Entities with respect to the Asset Contributed 
Systems or the Contributed

Entities has engaged in any activities involving the generation, use, 
handling or disposal of any Hazardous Substances; and (xi) the Company has 
delivered to Parent copies of all environmental reports, studies, sampling 
data, permits, government filings and other environmental information in its 
possession or reasonably available to it relating to any of the Contributed 
System Entities with respect to the Asset Contributed Systems or any of the 
Contributed Entities current or former properties or operations; and (xii) 
the indemnity with respect to environmental matters at the Mamaroneck, New

in favor of a Contributed Entity and will not be affected by the Contribution 
Closing.

would prevent the Merger or the Contribution from qualifying as an exchange 
governed by Section 351 of the Code.

contested in good faith.

          (ii)  None of the Contributed Entities, CSC, Parent or any 
Affiliate of CSC  will be required to make or fund any payment to an

whether such payment is reasonable compensation for personal services 
performed or to be performed in the future) as a result of the Contribution.

Disclosure Letter, none of the Contributed Entities or the Asset Contributed 
Systems is a party to or bound by, or has any obligation under, any tax 
sharing or similar Contract.

          (iv)  As used in this Agreement:  (A) "COMPANY'S GROUP" shall mean 
any "affiliated group" (as defined in Section 1504(a) of the Code without

          (m)  LABOR MATTERS. Except as set forth in Section 5.1(m) of the 
Company Disclosure Letter: (i) The business of each of the Contributed 
Systems and of each of the Contributed Entities is operating and has been 
operated in compliance with all Laws respecting employment and employment 
practices, terms and conditions of employment and wages and hours (including, 
without limitation, where applicable, the Immigration Reform and Control Act 
("IRCA"), the Worker Adjustment and Retraining Notification Act of 1988 
("WARN"), any such applicable Laws respecting employment discrimination, 
equal opportunity, affirmative action, employee privacy, wrongful or unlawful 
termination, workers' compensation, occupational safety and health

contemplated hereby, and none of the Contributed Systems or Contributed 
Entities is engaging in any unfair labor practice.

          (ii)  There is no labor strike, dispute, walkout, work stoppage,

salaries, commissions, bonuses, workers' compensation or other compensation 
for any services performed by them or amounts required to be reimbursed to

Contributed System Entities with respect to the Asset Contributed Systems and 
the Contributed Entities currently have and, to the knowledge of the Company, 
always have carried or had the benefit of such insurance as is required by 
Law. 

          (s)  OWNED REAL PROPERTY. (i) Section 5.1(s) of the Company

its Subsidiaries has received any notice of violation or claimed violation of 
any Real Property Law that has not since been cured, which violations,

Systems Material Adverse Effect or prevent or materially burden or materially 
impair the ability of the Company to consummate the Contribution and the 
other transactions contemplated hereby.

or is bound (together, the "CONTRIBUTED SYSTEMS LEASES"), none of which has 
been modified in any material respect except to the extent such modifications 
have been disclosed and copies made available to Parent prior to the date 
hereof. Each of the Contributed Systems Leases is in full force and effect.  
None of the Contributed Entities or Contributed System Entities, and, to the 
knowledge of the Company, no other party is, in default (with or without 
notice or lapse of time or both) under any Contributed Systems Lease in any 
material respect.  To the knowledge of the Company, no event has occurred and 
is continuing that constitutes (or with notice or the passage of time or 
both, could constitute) a default under any Contributed Systems Lease in any 
material respect.

Contributed Systems Leased Real Property:

          (ii)  The Contributed Entities and the Contributed System Entities

"INTELLECTUAL PROPERTY RIGHTS") that are used in the business of their 
respective Contributed Systems as currently conducted, except for any such 
failures to own, be licensed or possess that, individually or in the 
aggregate, are not reasonably likely to have a Contributed Systems Material 
Adverse Effect, and to the knowledge of the Company all such Intellectual 
Property Rights held by the Contributed Entities and the Contributed System 
Entities are valid and subsisting.

          (w)  BROKERS AND FINDERS.  Neither the Company nor any of its

          (x)  CABLE TELEVISION FRANCHISES.  (i)  Section 5.1(x) of the Company
Disclosure Letter sets forth all of the Contributed Systems and the approximate

receiving any level of cable television service from the Contributed Systems in
individually billed residential units and (y) the quotient obtained by dividing
the total billings to all subscribers in commercial venues or bulk-billed
multiple residential units by the predominant cable service rate charged by each
such Contributed System for the lowest tier of service that includes ESPN, MTV
and CNN, as of March 31, 1997 served by each such Contributed System. 
Section 5.1(x) of the Company Disclosure Letter sets forth the name of the legal
entity that owns or, if Future Contributed System Entities, will own each such
Contributed System and holds or will hold, as the case may be, the applicable
franchise and the identity and ownership interest and relationship to the

Systems have been made available to Parent.  The Contributed Entities and the
Contributed System Entities are in compliance with all such Cable Franchise

          (ii)  Except as set forth in Section 5.1(x) of the Company Disclosure
Letter, there exists no fact or circumstance that makes it reasonably likely
that any Contributed System Cable Franchise Agreement scheduled to expire in the
next five years will not be timely renewed on commercially reasonable terms. 
The Company has filed or caused to be filed with the appropriate Governmental
Entity all appropriate requests for renewal under the Communications Act of
1934, as amended, and the rules and regulations thereunder (the "COMMUNICATIONS

and is, in compliance in all material respects with the rules and regulations of
the Federal Communications Commission ("FCC") and none of the Company or any of
its Subsidiaries has received notice from the FCC of any violation of its rules
and regulations by any of the Contributed Entities or, with respect to the Asset
Contributed Systems, any of the Contributed System Entities.  

                                  -35-
<PAGE>

None of the applicable franchises for the Contributed Systems has been 
suspended or revoked. Neither the Company nor any of its Subsidiaries has 
received any notice of any such possible suspension or revocation, and no 
such suspension or revocation is pending or, to the knowledge of the Company, 
threatened.

          (iii)  The Contributed Systems and all related businesses of the
Contributed Entities or, with respect to the Asset Contributed Systems, the
Contributed System Entities are, and, while owned by the Company or any of its
Affiliates, have been, operated in compliance in all material respects with the
Communications Act and the Company has submitted or caused to be submitted to
the FCC all material filings, including but not limited to cable television

that are required under the rules and regulations of the FCC.  

          (iv)  The Contributed Entities or, with respect to the Asset
Contributed Systems, the Contributed System Entities have conducted all system
and microwave performance tests and all Cumulative Leakage Index ("CLI") related
tests applicable to the Contributed Systems and have maintained records which
accurately and completely reflect in all material respects all results required
to be shown thereon.  The Contributed Entities or, with respect to the Asset
Contributed Systems, the Contributed System Entities have corrected any
radiation leakage of the Contributed Systems required to be corrected in
connection with the monitoring obligations and have otherwise complied in all
material respects with all applicable CLI rules and regulations.  The
Contributed Systems are in compliance in all material respects with all signal
leakage criteria set forth in 47 CFR Section 76.611.

          (v)  For each relevant semi-annual reporting period, the Company has
timely filed or caused to be filed with the United States Copyright Office all
required Statements of Account in true and correct form, and has paid when due
all required copyright royalty fee payments in the correct amount, relating to
the Contributed Systems' carriage of television broadcast signals.

          (vi)  Other than requests of network non-duplication and syndicated
exclusivity protection, neither the Company nor any of the Contributed Entities
or any of the Company's Subsidiaries has received any requests, notices or
demands, whether written or oral, from the FCC or any other Governmental Entity,
challenging or questioning the rights of the Contributed Entities or Contributed
System 

                                        -36-
<PAGE>

Entities to operate the Contributed Systems or carry any signal or requesting 
signal carriage.  All of the broadcast television signals carried by the 
Contributed Systems are carried either pursuant to the must-carry 
requirements or pursuant to executed retransmission consent agreements, 
accurate, complete and correct copies of which have been made available to 
Parent.

          (vii)  The regulated rates for services and equipment charged by any
Contributed System, including the rates for any "MIGRATED PRODUCT TIERS" (as
such term is defined by the FCC as of the date of this Agreement), (I) comply in
all material respects with FCC's rules establishing maximum permitted rates for
regulated services and equipment, (II) have been approved by the FCC under a
rate settlement with the Company with respect to a Contributed System or (III)
are subject to an order by the FCC or other Governmental Entity requiring a
Contributed System to adjust such rates.  The Company has made available to
Parent accurate, complete, and correct copies of all FCC rate justification
forms and materials (including Forms 393, 1200, 1205, 1210, and 1240) filed with
the FCC and any other Governmental Entity for each of the Contributed Systems
that are required to file such forms and materials, and such forms have been
filed with the appropriate regulatory body in compliance in all material
respects with all applicable requirements.  The Company has also made available
to Parent an accurate, complete, and correct copy of any rate settlement
agreement entered into with the FCC affecting any Contributed System.  Section
5.1(x) of the Company Disclosure Letter lists each Contributed System and
regulated rate that is the subject of a pending challenge before the FCC or any
other Governmental Entity and the Governmental Entity before which each such
challenge is pending.  Section 5.1(x) of the Company Disclosure Letter lists
each Contributed System subject to an order described in subclause (III) above,
and the rate reduction required by each such order.

          (viii)  The Company has made available to Parent, to the extent it
possesses them, accurate, complete, and correct copies of each material inquiry,
request for information, report, directive, and similar communications received
by the Company or any of its Subsidiaries from the FCC or any other Governmental
Entity that relates to the obligations of the Contributed Entities with respect
to any of the Contributed Systems under the Communications Act.  The Company has
also made available to Parent a copy of each written response by the Company or
any of its Subsidiaries to each such inquiry, request for information, report,
directive, or similar communication.

the transferors receiving shares of Parent Common Stock in the Contribution is
an "accredited investor" within the meaning of the Securities Act and is
acquiring such shares for its own account and for investment purposes only and
not with a view to, or for resale in connection with, any distribution thereof

          (z)  DISCLOSURE.  No representation or warranty made by the Company in
this Agreement nor any document, written information, statement, financial

Company or any of its Subsidiaries or its representatives pursuant hereto or in
connection with the transactions contemplated hereby, when taken together,
contains or will contain any untrue statement of a material fact, or omits or
will omit to state a material fact necessary to make the statements or facts
contained herein or therein, in light of the circumstances under which they were

event, fact or condition that would have a Contributed Systems Material Adverse
Effect, or that reasonably could be expected to do so, that has not been set
forth in this Agreement, the Company Disclosure Letter or in the Schedules. 

          5.2  REPRESENTATIONS AND WARRANTIES OF CSC, PARENT AND MERGER SUB.

Merger Sub or Parent, (ii) no securities of Merger Sub or Parent convertible 
into or exchangeable for shares of capital stock or voting securities of 
Merger Sub or Parent, respectively, and (iii) no options or other rights to

liabilities or obligations of any nature other than those incident to its 
formation and pursuant to the Partnership Contribution, the Reorganization, 
this Agreement and the Transactions and the other transactions contemplated 
by this Agreement.  CSC and Parent have delivered to the Company true and

each jurisdiction where the ownership or operation of its properties or conduct
of its business requires such qualification, except where the failure to be so

                                      -39-

          As used in this Agreement, the term "PARENT MATERIAL ADVERSE EFFECT"

          (c)  CAPITAL STRUCTURE OF CSC.  The authorized capital stock of CSC

any securities of CSC or any of its Significant Subsidiaries, and no securities
or obligation evidencing such rights are authorized, issued or outstanding.  CSC
does not have outstanding any Voting Debt having the right to vote with the
stockholders of CSC on any matter.

          (d)  CORPORATE AUTHORITY.  (i)  Each of CSC, Parent and Merger Sub has
all requisite corporate power and authority and has taken all corporate action
necessary in order to execute, deliver and perform its obligations under this
Agreement and to consummate the Transactions, subject only to (A) any
stockholder approval necessary to permit the issuance of the shares of Parent
Common Stock required to be issued pursuant to the Contribution and (B) the vote
of a majority of the outstanding Shares voting together as a single class to
approve the Merger (together, the "PARENT REQUISITE VOTES").  This Agreement is
a valid and binding agreement of CSC, Parent and Merger Sub, enforceable against
each of them in accordance with its terms, subject to the Bankruptcy and Equity
Exception.

          (ii) Prior to the Effective Time, Parent will have taken all necessary
action to permit it to issue the number of shares of Parent Common Stock
required to be issued pursuant to the Contribution and the Merger.  The Parent
Common Stock, when issued in connection with the Contribution and the Merger,
will be validly issued, fully paid and nonassessable, and no stockholder of
Parent will have any preemptive right of subscription or purchase  in respect
thereof.

          (e)  GOVERNMENTAL FILINGS; NO VIOLATIONS.  (i)  Other than the filings

<PAGE>

Transactions and the other transactions contemplated hereby, except those 
that the failure to make or obtain are not, individually or in the aggregate, 
reasonably likely to have a Parent Material Adverse Effect or prevent or 
materially delay or materially impair the ability of CSC, Parent or Merger 
Sub to consummate the transactions contemplated by this Agreement.

          (ii) The execution, delivery and performance of this Agreement by CSC,
Parent and Merger Sub do not, and the consummation by CSC, Parent and Merger Sub
of the Transactions and the other transactions contemplated hereby will not,
constitute or result in (A) a breach or violation of, or a default under, the
certificate of incorporation or by-laws of CSC, Parent and Merger Sub or the
comparable governing instruments of any of their Significant Subsidiaries, (B) a
breach of or violation of or a default under, or the acceleration of any

Subsidiaries or any Law or governmental or non-governmental permit or license to
which CSC or any of its Significant Subsidiaries is subject or (C) any change in
the rights or obligations of any party under any of the Contracts, except, in
the case of clause (B) or (C) above, for any breach, violation, default,
acceleration, creation or change that, individually or in the aggregate, is not
reasonably likely to have a Parent Material Adverse Effect or prevent,
materially delay or materially impair the ability of CSC, Parent or Merger Sub
to consummate the transactions contemplated by this Agreement.  Section 5.2(e)
of the Parent Disclosure Letter sets forth a correct and complete list of
Contracts of CSC and its Significant Subsidiaries pursuant to which consents or
waivers are or may be required prior to consummation of the transactions
contemplated by this Agreement (whether or not subject to the material adverse
effect or materiality exception set forth with respect to clauses (B) and (C)
above), other than any such Contract (x) the amount that could be paid or
received thereunder after the CSC Audit Date does not exceed $100,000 per annum
and $250,000 in the aggregate or (y) that is terminable by the CSC or any of its
Significant Subsidiaries, as the case may be, without penalty on less than 60
days' notice.

          (f)  CSC REPORTS; FINANCIAL STATEMENTS.  CSC has delivered to the
Company each registration statement, report, proxy statement or information
statement prepared by it since December 31, 1996 (the "CSC AUDIT DATE"),
including (i) CSC's Annual Report on Form 10-K for the year ended 

                                    -42-
<PAGE>

December 31, 1996 and (ii) CSC's Quarterly Report on Form 10-Q for the period 
ended March 31, 1997, each in the form (including exhibits, annexes and any 
amendments thereto) filed with the SEC (collectively, including any such 
reports filed subsequent to the date hereof, the "CSC REPORTS").  As of their 
respective dates, the CSC Reports did not, and any CSC Reports filed with the 
SEC subsequent to the date hereof will not, contain any untrue statement of a 
material fact or omit to state a material fact required to be stated therein 
or necessary to make the statements made therein, in light of the 
circumstances in which they were made, not misleading.  Each of the 
consolidated balance sheets included in or incorporated by reference into the 
CSC Reports (including the related notes and schedules) fairly presents, or 
will fairly present, in all material respects, the consolidated financial 
position of CSC and its Subsidiaries as of its date and each of the 
consolidated statements of income and of changes in financial position 
included in or incorporated by reference into the CSC Reports (including any 
related notes and schedules) fairly presents, or will fairly present, in all 
material respects, the results of operations, retained earnings and changes 
in financial position, as the case may be, of CSC and its Subsidiaries for 
the periods set forth therein (subject, in the case of unaudited statements, 
to notes and normal year-end audit adjustments that will not be material in 
amount or effect), in each case in accordance with GAAP consistently applied 
during the periods involved, except as may be noted therein.

          (g)  ABSENCE OF CERTAIN CHANGES.  Except as disclosed in the CSC
Reports filed prior to the date hereof, since the CSC Audit Date, there has not
been (i) any change in the financial condition, properties, business or results
of operations of CSC and its Subsidiaries or any event or development or
combination of events or developments that, individually or in the aggregate,
has had or is reasonably likely to have a Parent Material Adverse Effect;
PROVIDED, HOWEVER, that any such effect resulting from any change (x) in law,
rule, or regulation or generally accepted accounting principles or
interpretations thereof that applies to both CSC or such Subsidiary and the
Contributed Systems or (y) in economic or business conditions generally or in
the cable industry or programming industry specifically shall not be considered
when determining if a Parent Material Adverse Effect has occurred; (ii) any
material damage, destruction or other casualty loss with respect to any material
asset or property owned, leased or otherwise used by CSC or any of its
Significant Subsidiaries, whether or not covered by insurance; (iii) any change
by CSC in accounting principles, practices or  

                                        -43-
<PAGE>

methods; or (iv) any declaration, setting aside or payment of any dividend or 
other distribution in respect of the capital stock of CSC or Parent, except 
for dividends or other distributions on its capital stock publicly announced 
prior to the date hereof and regular dividends in respect of the Preferred 
Shares.

          (h)  LITIGATION AND LIABILITIES.  Except as disclosed in the CSC
Reports filed prior to the date hereof, there are no (i) civil, criminal or
administrative actions, suits, claims, hearings, investigations or proceedings
pending or, to the knowledge of CSC, threatened against CSC or any of its
Affiliates or (ii) obligations or liabilities, whether or not accrued,
contingent or otherwise and whether or not required to be disclosed, including
those relating to environmental and occupational safety and health matters, or
any other facts or circumstances of which CSC has knowledge that could result in
any claims against, or obligations or liabilities of, CSC or any of its
Affiliates, except, in the case of either clause (i) or (ii) above, for those
that are not, individually or in the aggregate, reasonably likely to have a
Parent Material Adverse Effect or prevent or materially burden or materially
impair the ability of CSC, Parent or Merger Sub to consummate the transactions
contemplated by this Agreement.

          (i)  EMPLOYEE BENEFITS. (i)  A copy of each bonus, deferred
compensation, pension, retirement, profit-sharing, thrift, savings, employee
stock ownership, stock bonus, stock purchase, restricted stock, stock option,
employment, termination, severance, compensation, medical, health or other plan,
agreement, policy or arrangement that covers current or former employees or
directors of CSC and its Subsidiaries and is in effect on the date hereof, other
than multiemployer plans (the "CSC COMPENSATION AND BENEFIT PLANS"), and any
trust arrangement or insurance contract forming a part of such CSC Compensation
and Benefits Plans has been made available to the Company prior to the date
hereof.  The CSC Compensation and Benefit Plans are listed in Section 5.2(i) of
the Parent Disclosure Letter and any "change of control" or similar provision
therein are specifically identified in Section 5.2.(i) of the Parent Disclosure
Letter.

          (ii) All CSC Compensation and Benefit Plans are in substantial
compliance with all applicable Laws, including the Code and ERISA.  Each CSC
Compensation and Benefit Plan that is an "employee pension benefit plan" within
the meaning of Section 3(2) of ERISA (a "CSC PENSION PLAN") and that is intended
to be qualified under Section 401(a) of the Code has received a favorable
deter-

                                      -44-

<PAGE>

mination letter from the IRS with respect to TRA, and CSC is not aware of any 
circumstances likely to result in revocation of any such favorable 
determination letter.  As of the date hereof, there is no pending or, to the 
knowledge of CSC, threatened material litigation relating to the CSC 
Compensation and Benefit Plans.  Neither CSC nor any of its Subsidiaries has 
engaged in a transaction with respect to any CSC Compensation and Benefit 
Plan that, assuming the taxable period of such transaction expired as of the 
date hereof, would subject CSC or any of its Subsidiaries to a material tax 
or penalty imposed by either Section 4975 of the Code or Section 502 of ERISA.

          (iii) As of the date hereof, no liability under Subtitle C or D of 
Title IV of ERISA has been or is expected to be incurred by CSC or any 
Subsidiary with respect to any ongoing, frozen or terminated "single-employer 
plan", within the meaning of Section 4001(a)(15) of ERISA, currently or 
formerly maintained by any of them, or the single-employer plan of any entity 
which is considered an ERISA Affiliate of CSC.  CSC and its Subsidiaries have 
not incurred and do not expect to incur any withdrawal liability with respect 
to a multiemployer plan under Subtitle E to Title IV of ERISA.  No notice of 
a "reportable event", within the meaning of Section 4043 of ERISA for which 
the 30-day reporting requirement has not been waived, has been required to be 
filed for any CSC Pension Plan or by any ERISA Affiliate within the 12-month 
period ending on the date hereof or will be required to be filed in 
connection with the transactions contemplated by this Agreement.

          (iv) All contributions required to be made under the terms of any 
CSC Compensation and Benefit Plan or of the date hereof have been timely made 
or have been reflected on the most recent consolidated balance sheet filed or 
incorporated by reference in the CSC Reports prior to the date hereof.  
Neither any CSC Pension Plan nor any single-employer plan of an ERISA 
Affiliate of CSC has an "accumulated funding deficiency" (whether or not 
waived) within the meaning of Section 412 of the Code or Section 302 of 
ERISA.  Neither CSC nor its Subsidiaries has provided, or is required to 
provide, security to any CSC Pension Plan or to any single-employer plan of 
an ERISA Affiliate of CSC pursuant to Section 401(a)(29) of the Code.

          (v) Under each CSC Pension Plan which is a single-employer plan, as 
of the last day of the most recent plan year ended prior to the date hereof, 
the actuarially determined present value of all "benefit liabilities", within 
the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of 
the actuarial assumptions 


                                      -45-


<PAGE>


contained in the CSC Pension Plan's most recent actuarial valuation), did not 
exceed the then current value of the assets of such CSC Pension Plan, and 
there has been no material change in the financial condition of such CSC 
Pension Plan since the last day of the most recent plan year. The withdrawal 
liability of CSC and its Subsidiaries under each CSC Compensation and Benefit 
Plan which is a multiemployer plan, determined as if a complete withdrawal 
has occurred as of the date hereof, does not exceed $100,000.

          (vi) Neither CSC nor its Subsidiaries have any obligations for retiree
health and life benefits under any CSC Compensation and Benefit Plan, except as
set forth in the Parent Disclosure Letter.  CSC or its Subsidiaries may amend or
terminate any such plan under the terms of such plan at any time without
incurring any material liability thereunder.

          (vii) The consummation of the Transactions and the other transactions
contemplated by this Agreement will not (x) entitle any employees of CSC or its
Subsidiaries to severance pay, (y) accelerate the time of payment or vesting or
trigger any payment of compensation or benefits under, increase the amount
payable or trigger any other material obligation pursuant to, any of the CSC
Compensation and Benefit Plans or (z) result, in any material respect, in any
breach or violation of, or default under, any of the CSC Compensation and
Benefit Plans.

          (j)  COMPLIANCE WITH LAWS; PERMITS.  Except as set forth in the CSC
Reports filed prior to the date hereof, the businesses of each of CSC and its
Subsidiaries have not been, and are not being, conducted in violation of any
Laws, except for violations or possible violations that, individually or in the
aggregate, are not reasonably likely to have a Parent Material Adverse Effect or
prevent or materially burden or materially impair the ability of CSC, Parent or
Merger Sub to consummate the transactions contemplated by this Agreement. 
Except as set forth in the CSC Reports filed prior to the date hereof, no
investigation or review by any Governmental Entity with respect to CSC or any of
its Subsidiaries is pending or, to the knowledge of  CSC, threatened, nor has
any Governmental Entity indicated an intention to conduct the same, except for
those the outcome of which are not, individually or in the aggregate, reasonably
likely to have a Parent Material Adverse Effect or prevent or materially burden
or materially impair the ability of CSC, Parent or Merger Sub to consummate the
transactions contemplated by this Agreement.  To the knowledge of CSC, no
material change is required in CSC's or 


                                      -46-

<PAGE>

any of its Subsidiaries' processes, properties or procedures in connection 
with any such Laws, and CSC has not received any notice or communication of 
any noncompliance with any such Laws that has not been cured as of the date 
hereof except for noncompliance that is not, individually or in the 
aggregate, reasonably likely to have a Parent Material Adverse Effect or 
prevent or materially burden or materially impair the ability of CSC, Parent 
or Merger Sub to consummate the transactions contemplated by this Agreement.  
CSC and its Subsidiaries each has all permits, licenses, trademarks, patents, 
trade names, copyrights, service marks, franchises, variances, exemptions, 
orders and other governmental authorizations, consents and approvals 
necessary to conduct its business as presently conducted except those the 
absence of which are not, individually or in the aggregate, reasonably likely 
to have a Parent Material Adverse Effect or prevent or materially burden or 
materially impair the ability of CSC, Parent or Merger Sub to consummate the 
Transactions and the other transactions contemplated by this Agreement.

          (k)  TAX MATTERS.  As of the date hereof, neither CSC nor any of its
Affiliates has taken or agreed to take any action, nor does CSC have any
knowledge of any fact or circumstance, that would prevent the Merger, the
Contribution or the Partnership Contribution from qualifying as an exchange
governed by Section 351 of the Code.

          (l)  TAXES.  (i)  (A) All CSC Tax Returns that are required to be
filed by or with respect to the CSC Group have been duly and timely filed
(taking into account an extension of time within which to file) and all such
filed CSC Tax Returns are accurate and complete in all material respects; and
(B) all CSC Taxes shown to be due on the CSC Tax Returns referred to in clause
(A) have been paid in full, and all CSC Taxes required to be withheld from
amounts owing to any employee, creditor or third party have been withheld,
except in each case with respect to matters contested in good faith.

          (ii)  As used in this Agreement: (A) the term "CSC GROUP" means any
"affiliated group" (as defined in Section 1504(a) of the Code without regard to
the limitations contained in Section 1504(b) of the Code) that includes CSC or
any predecessor of or successor to CSC (or another such predecessor or
successor); (B) the term "CSC TAX" means any Tax imposed on the income,

Subsidiaries is a party to or otherwise bound by any collective bargaining 
agreement, contract or other agreement with a labor union or labor 
organization, nor, as of the date hereof, is CSC or any of its Significant 
Subsidiaries the subject of any material proceeding asserting that CSC or any 
of its Significant Subsidiaries has committed an unfair labor practice or is 
seeking to compel it to bargain with any labor union or labor organization 
nor is there pending or, to the knowledge of CSC, threatened, any labor 
strike, dispute, walk-out, work stoppage, slow-down or lockout involving CSC 
or any of its Significant Subsidiaries.

          (n)  INSURANCE.  All material fire and casualty, general liability, 
business interruption, product liability, property, workers compensation,

normal risks incident to the business of CSC and its Subsidiaries and their 
respective properties and assets, and are in character and amount at least 
equivalent to that carried by persons engaged in similar businesses and 
subject to the same or similar perils or hazards, except for any such 
failures to maintain insurance policies that, individually or in the

          (o)  BROKERS AND FINDERS.  Neither CSC or its Subsidiaries nor any 
of their officers, directors or employees has employed any broker or finder 
or incurred any liability for any brokerage fees or commissions or finders'

          (d)  except in the ordinary and usual course of business, make any
material change in the overall selling, pricing, advertising, distribution,

          (e)  other than bonuses that will not be the responsibility of or

described in the foregoing paragraphs (a) through (l).

          6.3. INFORMATION SUPPLIED.  TCI and CSC each agrees, as to itself and
its Subsidiaries, that none of the information supplied or to be supplied by it
or its Subsidiaries for inclusion or incorporation by reference in (i) the
Registration Statement on Form S-4 to be filed with the SEC by Parent in
connection with the issuance of shares of Parent Common Stock in the Merger
(including the proxy statement and prospectus (the "PROSPECTUS/PROXY STATEMENT")
constituting a part thereof) (the "S-4 REGISTRATION STATEMENT") will, at the
time the S-4 Registration Statement becomes effective under the Securities Act,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading, and
(ii) the Prospectus/Proxy Statement and any amendment or supplement thereto
will, at the date of mailing to stockholders and at the times of the meetings of
stockholders of CSC to be held in connection with the Merger and the other
transactions contemplated hereby, contain any untrue statement of a material
fact or omit to state any material fact required to


                                     -58-
<PAGE>

be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading.

          6.4. STOCKHOLDERS MEETING; PARENT VOTE ON REORGANIZATION;
RECOMMENDATION.  CSC will take, in accordance with applicable law and its
certificate of incorporation and by-laws, all action necessary to convene a
meeting of holders of Shares (the "STOCKHOLDERS MEETING") as promptly as
practicable after the S-4 Registration Statement is declared effective to
consider and vote upon the approval and adoption of this Agreement and, if
applicable, the issuance of Parent Common Stock pursuant to the Contribution.
Subject to fiduciary obligations under applicable law, each of CSC's and the
Parent's board of directors shall recommend such approval and shall take all
lawful action to solicit such approval.

          6.5. FILINGS; OTHER ACTIONS; NOTIFICATION. (a) CSC and Parent shall
promptly prepare and file with the SEC the Prospectus/Proxy Statement and shall
prepare and file with the SEC the S-4 Registration Statement as promptly as
practicable.  CSC and TCI shall use all reasonable efforts to have the S-4
Registration Statement declared effective under the Securities Act as promptly
as practicable after such filing, and promptly thereafter mail the
Prospectus/Proxy Statement to the stockholders of CSC.  CSC shall also use its
reasonable efforts to obtain prior to the effective date of the S-4 Registration
Statement all necessary state securities law or "blue sky" permits and approvals
required in connection with the Merger and will pay all expenses incident
thereto.

          (b)  TCI on the one hand and CSC and Parent on the other hand shall
cooperate with each other and use (and shall cause their respective Subsidiaries
to use) all reasonable best efforts to take or cause to be taken all actions,
and do or cause to be done all things, necessary, proper or advisable on its
part under this Agreement and applicable Laws to cause to be satisfied all of
the conditions set forth in Article VII and to consummate and make effective
each of the Transactions and the other transactions contemplated by this
Agreement as soon as practicable, including preparing and filing as promptly as
practicable all documentation to effect all necessary notices, reports and other
filings and to obtain as promptly as practicable all consents, registrations,
approvals, permits and authorizations necessary or advisable to be obtained from
any third party and/or any Governmental Entity in order to consummate each of
the Transactions or any of


                                     -59-
<PAGE>

the other transactions contemplated by this Agreement and responding as
promptly as practicable to any inquiries received from any Governmental
Entity in connection therewith.  TCI and CSC and Parent shall use their
respective reasonable best efforts to overcome any objections that may be
raised by any Governmental Entity to the consummation of the Contribution and
the other transactions contemplated by this Agreement.  In this regard, TCI
agrees that it shall agree to such modifications to or relinquishments of its
governance rights (including voting, consent and board representation rights)
as may be required to overcome any such objections; PROVIDED, that if TCI
agrees to modify or relinquish any governance right, CSC and Parent shall
provide contractual rights that approximate as nearly as reasonably
practicable the governance rights modified or relinquished.  Neither TCI nor
CSC or Parent shall be required to make any change in the operations or
activities of its or its Subsidiaries' business (or material assets employed
therein) if such change would be materially adverse to TCI and its
Subsidiaries, taken as an entirety, or to CSC or Parent and its Subsidiaries,
taken as an entirety, as the case may be, or to their respective cable
television businesses, taken as an entirety, or their respective programming
businesses, taken as an entirety, or to any of their respective Significant
Subsidiaries or any business (within the meaning of Rule 11-01(d) of
Regulation S-X promulgated under the Exchange Act) that, if it were a
Subsidiary, would be a Significant Subsidiary (it being agreed and understood
that any change that would prevent, modify or terminate any contractual
relationships among any of the parties hereto or any of their respective
Affiliates entered into after May 1, 1997 (excluding the agreements
contemplated in this Agreement) shall not be deemed to be materially
adverse). Subject to applicable laws relating to the exchange of information,
CSC, Parent and TCI each shall have the right to review in advance, and to
the extent practicable each will consult the other on, all the information
relating to CSC, Parent or TCI, as the case may be, and any of their
respective Subsidiaries, that may appear in any filing made with, or written
materials submitted to, any third party and/or any Governmental Entity in
connection with each of the Transactions and the other transactions
contemplated by this Agreement.  In exercising the foregoing right, each of
TCI, CSC and Parent shall act reasonably and as promptly as practicable.

          (c)  TCI, CSC and Parent each shall, upon request by the other,
furnish the other with all information concerning itself, its Subsidiaries,
directors, officers and stockholders and such other matters as may be reasonably


                                     -60-
<PAGE>

necessary or advisable in connection with the Prospectus/Proxy Statement, the
S-4 Registration Statement or any other statement, filing, notice or
application made by or on behalf of CSC, Parent, TCI or any of their
respective Subsidiaries to any third party and/or any Governmental Entity in
connection with each of the Transactions and the other transactions
contemplated by this Agreement.

          (d)  TCI and CSC and Parent each shall keep the other apprised of the
status of matters relating to completion of the transactions contemplated
hereby, including promptly furnishing the other with copies of notice or other
communications received by CSC or Parent or TCI, as the case may be, or any of
its Subsidiaries, from any third party and/or any Governmental Entity with
respect to the Transactions and the other transactions contemplated by this
Agreement.  The Company and CSC each shall give prompt notice to the other of
any change that is reasonably likely to result in a Contributed Systems Material
Adverse Effect or Parent Material Adverse Effect, respectively.

          (e)  As soon as practicable after the date hereof but in no event
later than 75 days after the date of the Original Agreement, the Company shall
prepare and deliver or cause to be prepared and delivered to CSC audited
financial statements and unaudited financial statements (collectively, the
"PROXY FINANCIAL STATEMENTS") for the combined operations of the Contributed
Systems in form and substance as is required in connection with the
Prospectus/Proxy Statement and the S-4 Registration Statement.  The Proxy
Financial Statements shall be prepared under the supervision of the audit
partner of KPMG Peat Marwick who is in charge of the CSC audit and in
cooperation and consultation with CSC and its Representatives.  CSC and the
Company shall each be responsible for one-half of the costs and reasonable
expenses associated with the audit and preparation required under this
paragraph; PROVIDED, that if the Contribution Closing is not consummated other
than as a result of a breach or default by CSC, Parent or Merger Sub, the
Company shall be responsible and pay or reimburse all of such costs and
expenses.

          6.6.  TAXATION.  Neither CSC, Parent or Merger Sub nor TCI shall take
or cause to be taken any action, whether before or after the Effective Time,
that would cause the Merger, the Contribution or, if applicable, the Partnership
Contribution not to qualify as an exchange governed by Section 351 of the Code.


                                     -61-
<PAGE>

          6.7.  ACCESS.  Upon reasonable notice, and except as may otherwise be
required by applicable law, TCI and CSC and Parent each shall (and shall cause
its Subsidiaries to) afford the other's officers, employees, counsel,
accountants and other authorized representatives ("REPRESENTATIVES") access,
during normal business hours throughout the period prior to the consummation of
the Contribution Closing, to its properties, books, contracts and records and,
during such period, each shall (and shall cause its Subsidiaries to) furnish
promptly to the other all information concerning its business, properties and
personnel as may reasonably be requested, PROVIDED that no investigation
pursuant to this Section shall affect or be deemed to modify any representation
or warranty made by the Company, CSC, Parent or Merger Sub, and PROVIDED,
FURTHER, that the foregoing shall not require TCI or CSC or Parent to permit any
inspection, or to disclose any information, that in the reasonable judgment of
TCI or CSC or Parent, as the case may be, would result in the disclosure of any
trade secrets of third parties or violate any of its obligations with respect to
confidentiality if TCI or CSC or Parent, as the case may be, shall have used
reasonable best efforts to obtain the consent of such third party to such
inspection or disclosure.  All requests for information made pursuant to this
Section shall be directed to an executive officer of the Company or CSC or
Parent, as the case may be, or such Person as may be designated by any of its
officers, as the case may be.  All such information shall be governed by the
terms of the Confidentiality Agreement.

          6.8.  CERTAIN CONTRACTS.  The Company agrees to take such action as
necessary so that at the Contribution Closing none of the Contributed Entities
is a party or Contributed Systems is subject to or bound by any programming,
affiliation or similar Contracts except as CSC may approve in writing prior to
the Contribution Closing Date or as set forth on Section 5.1(n) of the Company
Disclosure Letter.

          6.9.  STOCK EXCHANGE LISTING AND DE-LISTING.  CSC and Parent shall use
their respective best reasonable efforts to cause the shares of Parent Common
Stock to be issued in the Merger and pursuant to the Contribution (including any
shares of Parent Common Stock issuable upon conversion, exercise or exchange of
securities of Parent) to be approved for listing on the AMEX subject to official
notice of issuance, prior to the Closing Date.  The Surviving Corporation shall
use its best efforts to cause the CSC Class A Shares to be de-listed from the
AMEX and


                                     -62-
<PAGE>

de-registered under the Exchange Act as soon as practicable following the
Effective Time.

          6.10.  PUBLICITY.  The initial press release regarding the
Contribution shall be a joint press release by CSC and TCI, and the initial
press release(s) regarding the Partnership Contribution, the Reorganization
and/or the Merger shall be a press release by CSC, and thereafter TCI and CSC
and Parent each shall consult with each other prior to issuing any press
releases or otherwise making public announcements with respect to the
Contribution and prior to making any filings with any third party and/or any
Governmental Entity (including any national securities exchange) with respect
thereto, except as may be required by law or by obligations pursuant to any
listing agreement with or rules of any national securities exchange.

          6.11.  BENEFITS; BOARD REPRESENTATION; EMPLOYEES.

          (a)  STOCK OPTIONS; CONJUNCTIVE RIGHTS.

          (i) At the Effective Time, each outstanding option to purchase Shares
(a "CSC OPTION") under the CSC Stock Plans, whether vested or unvested, shall be
deemed to constitute an option to acquire, on the same terms and conditions as
were applicable under such CSC Option, the same number of shares of Parent
Common Stock subject to the CSC Option and at the same exercise price in effect
immediately prior to the Effective Time.  In addition, each of the outstanding
"conjunctive stock appreciation rights" and "bonus award shares" of CSC (as
described in the CSC Reports), whether vested or unvested, shall, at the
Effective Time be deemed to constitute a conjunctive stock appreciation right or
bonus award share of Parent, as the case may be, on the same terms and
conditions as were applicable under such conjunctive stock appreciation right or
bonus award share of CSC, as the case may be, as in effect immediately prior to
the Effective Time.

          (ii) Effective at the Effective Time, Parent shall assume each CSC
Option and conjunctive stock appreciation right or bonus award share of CSC in
accordance with the terms of the CSC Stock Plans and other arrangements, as the
case may be, under which it was issued and the stock option agreement or other
agreement, as the case may be, by which it is evidenced.  At or prior to the
Effective Time, Parent shall take all corporate action necessary to reserve for
issuance a sufficient number of shares of Parent Common Stock for delivery upon
exercise of CSC Options assumed by it in accordance with this Section.


                                     -63-
<PAGE>

As soon as practicable after the Effective Time, Parent shall file a
registration statement on Form S-3 or Form S-8, as the case may be (or any
successor or other appropriate forms), or another appropriate form with
respect to the Parent Common Stock subject to such CSC Options, and shall use
its best efforts to maintain the effectiveness of such registration
statements (and maintain the current status of the prospectus or prospectuses
contained therein) for so long as such CSC Options remain outstanding.

          (b)  ELECTION TO PARENT'S BOARD OF DIRECTORS.  Effective as of the
Effective Time, CSC shall cause two persons to be designated by TCI as soon as
reasonably practicable after the date hereof and no later than prior to the
substantial completion of the Proxy Statement/Prospectus to be appointed to
Parent's board of directors as designees of the Parent Class B Shares as
contemplated by the Stockholders Agreement.

          (c)  EMPLOYEES.  (i) Parent or CSC may, but shall have no obligation
to, employ or offer employment to any employee engaged in the business of a
Contributed System, including employees engaged in advertising sales for a
Contributed System.  Not less than 120 days (or such later date as the Company
and CSC may mutually agree) after the date of this Agreement, CSC shall provide
the Company a list, which may be updated by CSC from time to time to reflect
changes in employees or staffing after such date (provided such updates are not
material overall), of employees who will be offered employment after the Closing
Date (the "HIRED EMPLOYEES").  CSC shall coordinate the hiring procedures
relating to such Hired Employees with the Company.

          (ii)  The Company will pay or cause to be paid to all employees
employed in the Contributed Systems all compensation, including salaries,
commissions, bonuses, deferred compensation, severance, insurance, pensions,
profit sharing, vacation (other than vacation and sick leave which is allowed to
be carried over pursuant to Section 6.11(c)(iii)), sick pay and other
compensation or benefits to which they are entitled for periods prior to the
Contribution Closing, including, without limitation, all amounts, if any,
payable on account of the termination of their employment.  The Company agrees
to cooperate in all reasonable respects with CSC to allow CSC to evaluate and
interview employees of the Contributed Systems to make hiring decisions.


                                     -64-
<PAGE>

          (iii) The Company will remain solely responsible for, and will 
indemnify and hold harmless Parent and CSC from and against all losses 
arising from or with respect to, all salaries and all severance, vacation, 
medical, sick, holiday, continuation coverage and other compensation or 
benefits to which its employees may be entitled, whether or not such 
employees may be hired by CSC, as a result of their employment by it prior to 
the Contribution Closing, the termination of their employment prior to the 
Contribution Closing, the obligation, if any, to notify and/or bargain with 
any labor organization, the consummation of the transactions contemplated 
hereby or pursuant to any applicable legal requirement (including without 
limitation WARN) or otherwise relating to their employment prior to the 
Closing Time. All Hired Employees shall be entitled to carry forward all 
accrued vacation and sick leave limited to the maximum amount to be carried 
forward under Parent's standard policies.

          (iv)  Parent shall after the Contribution Closing provide employee 
benefit plans, programs and policies to Hired Employees that, in the 
aggregate, will provide benefits to such employees that are no less favorable 
in the aggregate than those provided to similarly situated employees of 
Parent and its Subsidiaries. Hired Employees of the Contributed System 
Entities and the Contributed Entities shall be given credit for all service 
with the Company, the Contributed System Entities and the Contributed 
Entities, or with any prior owner or operator of a Contributed System to the 
extent that such employee received time and grade credit from the Company, 
the Contributed System Entities and the Contributed Entities, under all 
employee benefit plans, programs and policies (including any bonus program) 
of Parent and its Subsidiaries in which they become participants for purposes 
of eligibility and vesting but not for purposes of benefit accrual. 
Notwithstanding the foregoing, the requirements of this subsection (c)(iv) 
shall not apply to employees who are covered by a collective bargaining 
agreement.

          (v)  Effective as of the Contribution Closing, all Hired  Employees 
shall cease to be covered by the Company's employee welfare benefit plans, 
including plans, programs, policies and arrangements which provide medical 
and dental coverage, life and accident insurance, disability coverage, and 
vacation and severance pay (collectively, "WELFARE PLANS") and all other 
employee benefit plans of the Company.

          (vi)  All claims and obligations under, pursuant to, or in 
connection with, any Welfare Plan or other 


                                      -65-

<PAGE>

employee benefit plan of the Company affecting employees of the Company or 
any of its Subsidiaries, including any Hired Employee, incurred on or before 
the Contribution Closing or resulting or arising from events or occurrences 
commencing or occurring on or before the Contribution Closing will remain the 
responsibility of the Company. The Company shall retain all obligations for 
payment of long- or short-term disability claims arising from disabilities 
that occurred prior to the Contribution Closing and up until such time as the 
employee returns to work with one of the Contributed Systems. Parent shall be 
responsible for payment of long and short-term disability claims that arise 
from disabilities that occur after the Contribution Closing, or any claims of 
a Hired Employee after such employee has returned to work with one of the 
Contributed Systems, on a full-time, unrestricted basis for at least 30 days.

          (vii)  If Parent or any of its Subsidiaries discharges any Hired 
Employee prior to 60 days following the Contribution Closing, Parent shall 
pay such discharged Hired Employee the severance benefits that would have 
been payable by the Company if such discharge had occurred prior to the 
Contribution Closing and the Company shall reimburse Parent and its 
Subsidiaries for all claims and obligations for any and all such benefits.  
Any claims or obligations arising in connection with any discharges of any 
Hired Employees after such date shall be the responsibility and obligation of 
the Parent and its Subsidiaries and not of the Company or its Subsidiaries.

          6.12.  EXPENSES.  The Surviving Corporation shall pay all charges 
and expenses in connection with the transactions contemplated in Article IV, 
and Parent shall reimburse the Surviving Corporation for such charges and 
expenses. Except as otherwise provided in Section 6.5(e) and Section 9.10, 
whether or not any of the Transactions are consummated, all costs and 
expenses incurred in connection with this Agreement and the Transactions and 
the other transactions contemplated by this Agreement shall be paid by the 
party incurring such expense.

          6.13.  INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.  (a) 
From and after the Effective Time, Parent shall indemnify and hold harmless, 
to the fullest extent permitted under applicable law (and Parent shall also 
advance expenses as incurred to the fullest extent permitted under applicable 
law; PROVIDED the Person to whom expenses are advanced provides an 
undertaking to repay such advances if it is ultimately determined that such 
Person is not entitled to indemnification), each present and former

director and officer of CSC and its Subsidiaries (collectively, the "D&O 
INDEMNIFIED PARTIES") against any costs or expenses (including reasonable 
attorneys' fees), judgments, fines, losses, claims, damages or liabilities 
(collectively, "COSTS") incurred in connection with any claim, action, suit, 
proceeding or investigation, whether civil, criminal, administrative or 
investigative, arising out of or pertaining to matters existing or occurring 
at or prior to the Effective Time, whether asserted or claimed prior to, at 
or after the Effective Time to the fullest extent that CSC or such Subsidiary 
would have been permitted as of the date hereof to indemnify such person.

          (b)  Any D&O Indemnified Party wishing to claim indemnification 
under paragraph (a) of this Section 6.13, upon learning of any such claim, 
action, suit, proceeding or investigation, shall promptly notify Parent 
thereof, but the failure to so notify shall not relieve Parent of any 
liability it may have to such D&O Indemnified Party except to the extent that 
such failure materially prejudices the indemnifying party. In the event of 
any such claim, action, suit, proceeding or investigation (whether arising 
before or after the Effective Time), any D&O Indemnified Party may retain 
counsel satisfactory to him or her, and Parent or the Surviving Corporation 
shall pay all reasonable fees and expenses of such counsel for the D&O 
Indemnified Party promptly as statements therefor are received. Parent and 
the Surviving Corporation will cooperate and assist in the defense of any 
such matter. If such indemnity is not available with respect to any D&O 
Indemnified Party, then the Surviving Corporation and the D&O Indemnified 
Party shall contribute to the amount payable in such proportion as is 
appropriate to reflect relative faults and benefits.

          (c)  The Surviving Corporation or Parent shall maintain CSC's 
officers' and directors' liability insurance ("D&O INSURANCE") on 
substantially the same terms as in existence on the date hereof for a period 
of six years after the Effective Time so long as such insurance can be 
obtained on commercially reasonable terms. Prior to the Effective Time, 
Parent shall enter into indemnification agreements with its officers and 
directors on the same terms and conditions as those contained in the 
indemnification agreements of the officers and directors of CSC as of the 
date hereof.

          (d)  The provisions of this Section are intended to be for the 
benefit of, and shall be enforceable by, each of the D&O Indemnified Parties, 
their heirs and their representatives.

          6.14.  PREFERRED SHARES. Prior to the Effective Time, CSC and

amended, to give effect to the consummation of the Merger and, if applicable, 
the Charter Amendments.

          6.15.  OTHER ACTIONS BY THE PARTIES. (a) TERMINATION OF AFFILIATED

have no debt, liability, commitment or other obligation of any kind 
whatsoever, whether known or unknown, choate or inchoate, secured or 
unsecured, accrued, fixed, absolute, contingent or otherwise, and whether due 
or to become due, to the Company or any of its Affiliates after the 
Contribution Closing (including (i) all borrowing and Contracts between (x) 
the Contributed Entities or any of the Asset Contributed Systems and (y) the 
Company or its Affiliates and (ii) any obligations to pay dividends or other 
distributions to the Company or any of its Affiliates), in all cases other

Letter and other than solely among the Contributed Entities. 

          (b)  STOCKHOLDERS AGREEMENT. At or prior to the Contribution 
Closing, Parent and TCI shall execute and deliver the Stockholders Agreement.

          (c)  OTHER TRANSACTIONS.  In addition, CSC, Parent and the 
Surviving Corporation shall consummate and cause to be consummated the 
following transactions:

          (i) At the Merger Closing and effective immediately after the 
Effective Time, Parent shall amend its certificate of incorporation to change 
its name to "Cablevision Systems Corporation".

purchase orders, invoices, brochures, labels, letterheads or billing 
documents and (B) the right (I) for a period of 120 days following the date

with the conduct of their businesses after such date, to include a statement 
indicating that, prior to being acquired by Parent, the businesses of the 
Contributed Entities and the Asset Contributed Systems were conducted under 
their respective corporate names prior to the Contribution Closing and (II) 
to the extent required by applicable law, to indicate by footnote or other 
similar device that information concerning prior financial or operating 
performance results or other similar historical information about the 
Contributed Systems arose when they conducted their respective businesses 
under their respective corporate or business names prior to the Contribution 
Closing.

          (e)  CERTAIN ENVIRONMENTAL MATTERS. Notwithstanding anything to the 
contrary in this Agreement, the Company shall protect, defend, indemnify and 
hold harmless Parent, CSC and their principals, shareholders, directors, 
officers, affiliates, agents, and employees ("INDEMNIFIED PARTIES"), from and 
against any and all claims, demands, losses, expenses, damages, liabilities, 
fines, penalties, charges, administrative and judicial proceedings, orders, 
judgments, remedial action requirements, investigations, property or personal 
injury claims, natural resource damage claims, enforcement actions and all 
costs and expenses incurred in connection therewith (including reasonable 
attorneys' fees and expenses) arising under or relating to any Environmental 
Laws and asserted by any Person other than any of the Indemnified Parties in 
connection with any release or contamination ("PRE-EXISTING CONTAMINATION") 
involving Hazardous Substances (whether in soil, water, air or structures) 
that at or prior to the Contribution Closing existed at or emanated from 
property owned by UA-Columbia Cablevision of Westchester, Inc. generally 
known as 604-612 Fayette Avenue and 605-609 Center Avenue in Mamaroneck, New 
York excluding only environmental liabilities (i) for which a Contributed 
Subsidiary is able to recover under the September 1, 1988 agreement between 
George and Brenda Lane, UA-Columbia Cablevision of Westchester, Inc., 
Electro-Materials Corp. of America and Rohm and Haas Company or (ii) that are 
not attributable to Pre-Existing Contamination. This indemnity shall survive 
indefinitely and shall be binding upon the successors and assigns of the 
Company, Parent and  CSC. To the extent that the Company shall have 
indemnified any of the Indemnified Parties pursuant to this 


                                      -69-

<PAGE>

Section 6.15(e), the Company shall have a right of subrogation as to claims

Indemnified Parties shall assign to the Company their rights against such 
other Person.

          (f)  FURTHER ACTIONS.  The Company, Parent and the Surviving 
Corporation shall enter into, file and perform all such agreements, 
indentures, charter amendments, certificates of designation, documents, 
certificates, stockholder and director consents and such other instruments as 
are required, advisable or desirable in order to give full effect to this 
Section 6.15 and to the Partnership Contribution in accordance with the 
Partnership Contribution Agreement.
  
          6.16.  PARENT, CSC AND THE COMPANY VOTES.  Parent, CSC and the 
Company shall vote (or consent with respect to) or cause to be voted (or a 
consent to be given with respect to) any shares of capital stock of Merger 
Sub, the Surviving Corporation and Parent, respectively, beneficially owned 
by it or any of its Affiliates or with respect to which it or any of its 
Affiliates has the power (by agreement, proxy or otherwise) to cause to be 
voted (or to provide a consent), in favor of the adoption and approval of 
this Agreement and any and all of the Transactions at any meeting of 
stockholders of CSC, Parent, Merger Sub or the Surviving Corporation at which 
this Agreement and/or any or all of the Transactions shall be submitted for 
adoption and approval and at all adjournments or postponements thereof (or, 
if applicable, by any action of stockholders of CSC, Parent, Merger Sub or 
the Surviving Corporation by consent in lieu of a meeting). 

          6.17.  RELEASED INDEBTEDNESS AND FIBERTECH CASH; COMPANY 
RESTRUCTURING; TAX SHARING; SURETY LIABILITIES; AND DISCLOSURE UPDATES:  (a) 
RELEASED INDEBTEDNESS AND FIBERTECH CASH.  Without limiting the generality of 
any other provisions of this Agreement, prior to the Contribution Closing the 
Company shall take any and all actions necessary or appropriate so that the 
Contributed Entities shall have no, and the Asset Contributed Systems shall 
not be subject to or encumbered by any, outstanding Indebtedness as of the 
Contribution Closing, in both cases other than (I) an aggregate amount of 
debt for borrowed money, including in such amount the principal of such debt 
and any interest accrued thereon and fees and other amounts payable in 
respect thereof, not to exceed (assuming payment in full at the Contribution 
Closing) $669,000,000 (the "ASSUMED COMPANY DEBT") at the consummation of the 


                                      -70-

<PAGE>

Contribution Closing, (II) Liabilities not material in amount and accounted 
for in Section 3.4. and (III) any debt obligations or other liabilities 
solely among the Contributed Entities. The Assumed Company Debt will be due 
and payable in full as of the Contribution Closing and the parties agree 
that, notwithstanding any other provision of this Agreement to the contrary: 
(i) the existence of the Assumed Company Debt, or the occurrence of a default 
thereunder as a result of the Contribution, shall not cause the Company to be 
in breach or default of any of its representations, warranties, covenants or 
agreements in this Agreement; and (ii) CSC or Parent, as of the Contribution 
Closing, shall pay or cause to be paid the Assumed Company Debt in full, or 
shall cause the Company and any of its Affiliates (other than Parent and its 
Subsidiaries, including, after the Contribution Closing, the Contributed 
Entities) that are liable (directly or contingently) for payment of the 
Assumed Company Debt to be unconditionally released from any liability with 
respect to the Assumed Company Debt. In the event that the Company or any of 
its Subsidiaries receive any cash ("Fibertech Cash") in respect of any 
prepayments of the Facilities Lease Agreement dated June 1, 1995 between TKR 
Cable Company (Owner) and New Jersey Fiber Technologies (Operator), the 
Company shall cause all such cash to remain as and be included as an asset of 
the Contributed Entities and Asset Contributed Systems up to and through the 
Contribution Closing.

          (b)  COMPANY RESTRUCTURING.  Prior to the Contribution Closing, the 
Company shall take or cause to be taken the actions described in Section 
6.17(b) of the Company Disclosure Letter (the "COMPANY RESTRUCTURING"), so 
that, immediately prior to the Contribution Closing, all of the Asset 
Contributed Systems will be owned by the Contributed System Entities, all of 
the Included Contributed Systems will be owned by the Contributed Entities 
and all of the outstanding capital stock of the Contributed Entities will be 
owned by the Company or one or more of its Subsidiaries. The Company 
covenants and agrees that none of the actions taken by it or any of its 
Affiliates in connection with the Company Restructuring shall cause a breach 
or default by the Company of any of its representations, warranties, 
covenants or agreements in this Agreement.

          (c)  TAX SHARING AGREEMENTS.  Any obligations and Contracts 
disclosed on Section 5.1(l) of the Company Disclosure Letter shall be 
terminated as of immediately prior to the Contribution Closing without 
subjecting any 


                                      -71-

<PAGE>

Contributed Entity or any Asset Contributed System to any liability.

          (d)  SURETY LIABILITIES.  Prior to the Contribution Closing, the 
Company shall take any and all actions necessary or appropriate so that the 
Contributed Entities shall have no outstanding Surety Liabilities (or 
obligations to incur Surety Liabilities) and so that the Asset Contributed 
Systems shall not be encumbered by or subject to any outstanding Surety 
Liabilities (or obligations to incur Surety Liabilities), in both cases, 
other than an aggregate amount not to exceed $10,000,000 and other than 
Liabilities accounted for in Section 3.4. CSC or Parent shall cause the 
Company and any of its Affiliates including the Contributed System Entities 
(other than Parent and its Subsidiaries, including, after the Contribution 
Closing, the Contributed Entities) that are liable (directly or contingently) 
under the Surety Liabilities to be unconditionally released from any 
liability with respect to the Surety Liabilities.

          (e)  DISCLOSURE UPDATES AND SUPPLEMENTS.  On the third business day 
before the Closing Date, the Company shall deliver to Parent a supplement to 
the Company Disclosure Letter as of such date, which supplement shall reflect 
the consummation of the Company Restructuring but shall not, except as 
otherwise expressly noted in this Agreement, be deemed to modify in any 
respect the Company Disclosure Letter.

obtained the consent or approval of each Person whose consent or approval 
shall be required under any Contract to which CSC or any of its Subsidiaries

Sub to consummate the Merger.

cooperate with each other and use all reasonable best efforts to minimize any
adverse effects that may result from consummating the Contribution Closing

                                      -76-
<PAGE>

Section 7.3(a) shall be deemed to have been satisfied even if such
representations or warranties are not so true and correct unless the failure of
such representations or warranties to be so true and correct, individually or in
the aggregate, has had, or is reasonably likely to have, a Contributed Systems
Material Adverse Effect or is reasonably likely to prevent or to materially
burden or materially impair the ability of the Company to consummate the
Contribution.

likely to prevent or to materially burden or materially impair the ability of
the Company to consummate the Contribution.

burden or materially impair the ability of CSC or Parent to consummate the
Contribution.

                         (Terms of Reorganization Agreement)

TERMS:

1.   Simultaneously with the Contribution Closing and/or the Partnership
     Contribution, or thereafter, Parent may transfer or cause to be transferred
     all or part of the Acquired Assets, the Assumed Liabilities and the
     Contributed Subsidiary Capital Stock to one or more direct Subsidiaries of
     Parent (each a "First-Tier Transferee Subsidiary") or to one or more direct
     Subsidiaries of a First-Tier Transferee Subsidiary.  

2.   The stock of one or more of the First-Tier Transferee Subsidiaries may be
     transferred to an entity that is a member of the CSC Group and that holds
     directly or indirectly the other cable properties of the CSC Group.

3.   Notwithstanding anything to the contrary in the foregoing paragraphs,
     (a) the stock of each First-Tier Transferee Subsidiary shall continue to be
     held directly by Parent for a period of at least one year after the Closing
     Date and (b) CSC will not transfer or distribute to Parent substantially
     all of its assets outside the ordinary course of business and will not be
     merged into Parent or liquidated or wound-up for a period of at least one
     year after the Closing Date, unless in the case of (a) or (b) either
     (i) the Company has consented to the stock of such First-Tier Transferee
     Subsidiaries ceasing to be held directly by Parent, or to such transfer,
     distribution, merger, liquidation or winding-up of CSC, as applicable, or
     (ii) CSC or Parent has obtained a ruling from the Internal Revenue Service
     to the effect that a transaction pursuant to which the stock of such
     First-Tier Transferee Subsidiaries ceases to be held directly by Parent
     prior to the expiration of such one-year period, or pursuant to which CSC
     transfers or distributes substantially of its assets to Parent or is
     merged, liquidated or wound-up, as applicable, will not cause the
     Contribution and the Merger not to qualify as an exchange governed by
     Section 351

accounting treatment of such business combination as a pooling of interests; or

          (e)  advise, assist (including by knowingly providing or arranging
financing for that purpose) or knowingly encourage, induce or attempt to
encourage or induce any other Person to take any actions referred to in the

                                   -12-
<PAGE>


case may be, under this Agreement; PROVIDED, FURTHER, that such Controlled
Subsidiary or wholly owned Subsidiary, as the case may be, and the Company shall
prior to such Transfer covenant and agree with Parent and the Class B Entities
that, for so long as the Controlled Subsidiary or wholly owned Subsidiary, as
the case may be, Beneficially Owns such Shares, it shall continue to be a
Controlled Subsidiary or wholly owned Subsidiary, as the case may be, of the
Company;

          (b)  a Transfer of all or any of such Shares to any Person such that

not Beneficially Own, after giving effect to such Transfer, Voting Securities of
Parent constituting 10% or more of the outstanding Parent Class A Shares or
Shares constituting 5% or more of the Outstanding Share Capital; PROVIDED, that
the Investor shall not, and shall not suffer or permit any Subsidiaries of the

Affiliates or Associates of the Investor to (and shall use all reasonable best
efforts to cause such Affiliates and Associates not to), in any case, form, join
or participate in or encourage the formation of a Group with such Person or any
Affiliates or Associates of such Person;

          (c)  a sale of all or any of such Shares to any Person that is

          (d)  a Transfer of all or any of such Shares to underwriters in
connection with an underwritten public offering of such Shares on a firm

of such Shares to any Class B Entity;

          (g)  a Transfer of all or any of such Shares in a BONA FIDE pledge of
such Shares to a financial institution to secure borrowings as permitted by
applicable Law; PROVIDED, that contemporaneously with such pledge such financial
institution agrees with Parent that upon any foreclosure on such pledge it shall
be bound by the obligations of the Company and the Investor under this Agreement
(but shall not have any of the rights of the Company and the Investor under this
Agreement except as provided in this Section and in Sections 11, 14(c), 15 and
16 pursuant to an assignment effected in accordance with the terms hereof); or

          (h)  a Transfer of all (but not less than all) of such Shares to any
Person after complying with all of the provisions set forth in Section 9;
PROVIDED, that contemporaneously with such Transfer (i) such Person becomes a
party to a counterpart of this Agreement as the Investor (whereupon, subject to
Section 16(f), any reference to the Investor herein shall be deemed to be a
reference to such Person), (ii) if such Person is a Subsidiary of any other
Person that is not a natural person, the Ultimate Parent Entity of such Person
shall also become a party to a counterpart of this Agreement and assume all
obligations of the Company hereunder (whereupon, subject to Section 16(f), any
reference to the Company herein shall be deemed to be a reference to such
Ultimate Parent Entity) and (iii) such Person causes to be delivered to Parent a
legal opinion of counsel of national standing, in form and substance reasonably
acceptable to Parent, to the effect set forth in Sections 2(b) and 2(c).

          (7) THE COMPANY'S RIGHT OF CONSULTATION WITH PARENT AND THE CLASS B
ENTITIES.  The Company, Parent and the Class B Entities hereby agree with each
other that, until the date that the Investor ceases to be entitled to nominate
two Investor Directors pursuant to Section 11(a) or, if earlier and at such time
the Investor does not Beneficially Own at least 33% of the Outstanding Share
Capital or such lesser percentage that results solely from  any dilution for
issuances for which no preemptive rights under Section 10 are given to the
Investor or results solely from dilution for issuances for which no
anti-dilution adjustment was 

                                -14-
<PAGE>

required to be made under the Merger Agreement, ten years from the date 
hereof, the Company, Parent and the Class B Entities shall be entitled to the 
respective rights and be subject to the respective obligations set forth in 
this Section:  

          (a)  NOTICE.  Prior to (i) the Class B Entities effecting a Transfer
(other than in a BONA FIDE pledge or grant of security interest to a financial
institution to secure borrowings) of Shares to any Person (other than any Class
B Entity or any Qualified Parties or Controlled Subsidiaries of any Class B
Entities) in any transaction or series of transactions pursuant to which there
is a Transfer of Shares that would constitute at least 10% of the Total Voting
Power, (ii) Parent or its Subsidiaries effecting a Transfer (other than in a
BONA FIDE pledge or grant of security interest to a financial institution to
secure borrowings) of Beneficial Ownership of capital stock or other equity
interests in any Restricted Subsidiary other than to Parent or to a Controlled
Subsidiary or stockholders of Parent or (iii) Parent or its Subsidiaries
effecting a Transfer (other than in a BONA FIDE pledge or grant of security
interest to a financial institution to secure borrowings) of a substantial
portion of the assets of Parent or any Restricted Subsidiary other than to
Parent or to a Controlled Subsidiary of Parent (collectively, a "Transfer
Transaction"), Parent or the Class B Entity desiring to make such a Transfer
shall first notify the Company in writing (a "Proposal Notice") of the
possibility of such a transaction and the number of and a description of the
interests contemplated to be Transferred.

          (b)  CONSULTATION.  Following the Company's receipt of the Proposal
Notice, Parent or the Class B Entity sending the notice shall discuss with the
Company the possibility of effecting a Transfer Transaction with the Company. 
If the Company wishes to pursue such a transaction and is capable of completing
a Transfer Transaction, then, for a period of 30 days after the Company's
receipt of the Proposal Notice (or such shorter period if the Company responds
in writing that it is not interested in pursuing such a transaction), Parent or
the Class B Entity shall negotiate in good faith and exclusively with the
Company to determine whether it is possible to agree to a Transfer Transaction
with the Company but shall not be obligated to enter into any agreement with the
Company to do so.  Parent or the Class B Entity shall be free to negotiate and
to initiate and hold discussions with other potential 

                                  -15-

<PAGE>

purchasers at any time before the Proposal Notice or after the expiration of 
such 30-day or shorter period and may agree to enter into a Transfer 
Transaction at any time after the expiration of such 30-day or shorter period 
even if such Transfer Transaction has a lower value to Parent or the Class B 
Entity than any transaction proposed by the Company.  The Company agrees to 
keep confidential the fact that Parent or a Class B Entity is considering 
effecting a Transfer Transaction, the possible terms thereof and any 
confidential information obtained by the Company in pursuing negotiations 
contemplated by this Section or otherwise obtained from Parent or any of the 
Class B Entities or their respective representatives.

          (8) THE INVESTOR'S TAG-ALONG RIGHTS; THE CLASS B ENTITIES' DRAG-ALONG
RIGHTS.  The Company and the Class B Entities hereby agree with each other that,
for so long as the Parent Class B Shares are entitled in accordance with their
terms to elect 75% of the Board or until this Section 8 terminates as provided
in Section 16(f), the Company and the Class B Entities shall be entitled to the
respective rights and subject to the respective obligations set forth in this
Section:

          (a)  TAG-ALONG.     If any Class B Entity proposes to Transfer any
Shares Beneficially Owned by it to any Person (other than any Class B Entity or
any Qualified Parties or Controlled Subsidiaries of any Class B Entities) in a
transaction or series of transactions pursuant to which such Person, together
with Affiliates and Associates of such Person (excluding from such Affiliates or
Associates any Class B Entity or any Qualified Parties or Controlled
Subsidiaries of any Class B Entities) (a "Tag-Along Transaction"), would become
the Beneficial Owner of Voting Securities of Parent that have the power to cast
at least 50% of the votes entitled to be cast in elections of directors of
Parent, the Investor shall be given the opportunity and shall have the right to
Transfer such number (but no less or more than such number) of the Shares then
Beneficially Owned by the Investor that is the same in proportion to the total
number of Shares that are Beneficially Owned by the Investor as the proportion
of the number of Shares being or to be Transferred by the Class B Entities
concurrently to such Person in the transaction or series of transactions
constituting the Tag-Along Transaction to the total number of Shares that are
Beneficially Owned by all of the Class B Entities on terms (including the form
and amount of, and the time of receipt 


                                     -16-
<PAGE>

of, consideration therefor) and conditions identical in all material respects 
to those applicable to such Class B Entity in connection with such Transfer.  
Any such Class B Entity shall give written notice to the Investor setting 
forth in detail the material terms and conditions of the applicable proposed 
Transfer, and the Investor shall have at least ten business days after such 
notice is given within which to exercise its rights contained in this Section 
by written notice thereof given to such Class B Entity (it being understood 
and agreed that, if no such notice is received by such Class B Entity within 
such period, the Investor shall be deemed to have elected not to have 
exercised its rights under this Section).  Any such notice shall constitute 
an irrevocable offer by the Investor to sell to such Person such Shares on 
the terms and conditions received by any such Class B Entity in connection 
with such Transfer.

          (b)  DRAG-ALONG.    If the Investor does not exercise the rights set
forth in the foregoing paragraph (a), then any Class B Entity that is
Transferring Shares to a Person (other than any Class B Entity or any Qualified
Parties or Controlled Subsidiaries of a Class B Entity or any Person that before
entering into the definitive documentation relating to such Transfer was an
Associate or Affiliate of any Class B Entity or of a Qualified Party of a Class
B Entity) in a transaction or series of transactions pursuant to which such
Person, together with Affiliates and Associates of such Person (excluding from
such Affiliates or Associates any Class B Entity or any Qualified Parties or
Controlled Subsidiaries of any Class B Entities) (a "Drag-Along Transaction"),
would become the Beneficial Owner of Voting Securities of Parent that have the
power to cast at least 50% of the votes entitled to be cast in elections of
directors of Parent may give written notice to the Investor during the period
expiring on the close of business on the tenth business day following the
expiration of the five business day period set forth in the foregoing paragraph
(a) requiring the Investor to Transfer such number (but no less or more than
such number) of the Shares then Beneficially Owned by the Investor that is the
same in proportion to the total number of Shares that are Beneficially Owned by
the Investor as the proportion of the number of Shares being or to be
Transferred by the Class B Entities concurrently to such Person in the
transaction or series of transactions constituting the Drag-Along Transaction to
the number of Shares that are Beneficially Owned by the Class B Entities on
terms (including the form and amount of, and the time of receipt of,
consideration therefor) and conditions no less 


                                     -17-
<PAGE>

favorable in all material respects to those applicable to such Class B Entity 
(and its Affiliates and Associates) in connection with such Transfer. 

           (c)  PARITY; CLOSING.   The terms on which the applicable Class B
Entity actually Transfers its Shares shall not be materially more favorable to
the Class B Entity (and its Affiliates, Associates and Qualified Parties), and
include no more cash, than the terms set forth in the notice given by it
pursuant to the foregoing paragraph (a).  The Investor shall give the same
representations, warranties, covenants and agreements as are given by the Class
B Entity in connection with any Transfer pursuant to this Section, but only
insofar as they relate to the Investor's ownership of Shares or are
representations and warranties to the effect set forth in Section 2, and shall
take all such actions as may be necessary to permit such Transfer to lawfully
occur.  The closing of the purchase and sale of the Investor's Shares by any
Person pursuant to this Section shall, to the extent legally practicable, take
place at the same time and place as the closing of the Transfer by any such
Class B Entity giving rise to the tag-along rights and drag-along rights set
forth in this Section.  At such closing, (i) the Investor shall deliver to such
Person certificates representing the Shares being sold, free and clear of any
Lien (and the Investor hereby represents and warrants to the Class B Entities
and shall represent and warrant to such Person that such Shares shall,
immediately prior to such sale, be so free and clear), (ii) such Person shall
deliver to the Investor the consideration to be paid for such Shares in
accordance with the terms of the purchase and sale of such Shares and (iii) the
Investor shall execute such other documents and take such other action as shall
be reasonably necessary to consummate the purchase and sale of such Shares;
PROVIDED, that if the Investor is required to Transfer Shares pursuant to a
Class B Entity's exercise of its drag-along rights, the Investor shall not be
required to enter into any noncompete or other agreement that in any material
respect restricts or has an adverse effect on the business or operations of the
Investor or any of its Affiliates.

          9. PARENT'S RIGHT OF CONSULTATION WITH THE
INVESTOR.  The Company and Parent hereby agree with each other that the Company
and Parent shall be entitled to the respective rights and subject to the
respective obligations set forth in this Section:

          (a)  NOTICE.   If at any time the Investor desires to Transfer in a
transaction or series of transactions any Shares to any other Person pursuant to
Section 6(h), the Investor shall first notify Parent in writing (an "Investor
Proposal Notice") of the possibility of such a transaction,  the number of
Shares proposed to be Transferred and the aggregate number of and a description
of the Shares that are Beneficially Owned by the Investor.

          (b)  CONSULTATION.  Following Parent's receipt of an Investor Proposal
Notice the Investor shall discuss with  Parent the possibility of effecting such
a transaction with Parent.  If Parent wishes to pursue such a transaction and is
capable of completing such a transaction, then, for a period of 30 days after
Parent's receipt of the Investor Proposal Notice (or such shorter period if
Parent responds in writing that it is not interested in pursuing such a
transaction), the Investor shall negotiate in good faith and exclusively with
Parent to determine whether it is possible to agree to such a transaction with
Parent but shall not be obligated to enter into any agreement with Parent to do
so.  The Investor shall be free to negotiate and to initiate and hold
discussions with other potential purchasers at any time before the Investor
Proposal Notice or after the expiration of such 30-day or shorter period and may
agree to enter into such a transaction at any time after the expiration of such
30-day or shorter period even if such transaction has a lower value to the
Investor than any transaction proposed by Parent.  Parent agrees to keep
confidential the fact that the Investor is considering effecting such a
transaction, the possible terms thereof and any confidential information
obtained by Parent in pursuing negotiations contemplated by this Section.

          10.  THE INVESTOR'S PREEMPTIVE RIGHTS.  The Company and Parent hereby
agree with each other that the Investor and Parent shall be entitled to the
respective rights and subject to the respective obligations set forth in this
Section:  

          (a)  NOTICE; EXERCISE; CLOSING.    If Parent proposes to issue, grant
or sell Shares, Parent shall give 


                                     -19-
<PAGE>

to the Investor a written notice setting forth in reasonable detail the per 
share consideration (including, in the case of any convertible or derivative 
security, the issue consideration pro rated per Share for such security) and 
other terms on which such Shares are proposed to be issued, granted or sold 
and the amount thereof proposed to be issued, granted or sold.  The Investor 
shall thereafter have the preemptive right, exercisable by notice to Parent 
no later than 15 days after Parent's notice is given, to purchase up to such 
number of Parent Class A Shares so that, after giving effect to such 
issuance, grant or sale and the preemptive subscription by the Investor, the 
Investor, together with its Affiliates and Associates, will Beneficially Own 
in the aggregate the same proportion of the Outstanding Share Capital as 
Beneficially Owned as of the date of Parent's notice, for the consideration 
in cash and on the other terms set forth in Parent's notice.  Any written 
notice by the Investor exercising the right to purchase Shares pursuant to 
this Section shall constitute an irrevocable commitment to purchase from 
Parent the Shares specified in such notice, subject to the maximum set forth 
in the preceding sentence.  The closing of the purchase of Shares by the 
Investor shall, to the extent legally practicable, take place at the same 
time and place as the closing of such issuance, grant or sale to the Persons 
giving rise to the preemptive rights set forth in this Section and if not at 
the same time shall take place as soon thereafter as is practicable; PROVIDED 
that such closing shall, to the extent applicable, be conditioned upon the 
expiration or termination of any waiting period under the HSR Act and the 
making of any necessary filings with and obtaining of any approvals from any 
Governmental Entities except those that the failure to make or obtain are 
not, individually or in the aggregate, reasonably likely to have a Parent 
Material Adverse Effect or a material adverse effect on the financial 
condition, properties, business or results of operations of the Company and 
its Subsidiaries taken as a whole.  At such closing, (i) Parent shall deliver 
to the Investor certificates representing the Shares being subscribed, and 
such Shares will be validly issued, fully paid and nonassessable, (ii) the 
Investor shall deliver to Parent the consideration to be paid for such Shares 
and (iii) the Investor and Parent shall execute such other documents and take 
such other action as shall be reasonably necessary to consummate the 
subscription of such Shares.

          (b)  NON-EXERCISE.  From the expiration of the 15-day period first
referred to in the foregoing paragraph (a) 


                                     -20-
<PAGE>

and for a period of 90 days thereafter, Parent may offer, issue, grant and 
sell to any Person up to the amount of Shares set forth in Parent's notice 
relating to such Shares for a price and other terms no less favorable to 
Parent, and including no less cash, than those set forth in such notice 
(without deduction for reasonable underwriting, sales agency and similar fees 
payable in connection therewith); PROVIDED, HOWEVER, that Parent may not 
issue, grant or sell Shares in an amount greater than the amount set forth in 
such notice minus the amount purchased or committed to be purchased by the 
Investor upon exercise of its preemptive rights without granting the Investor 
the preemptive rights in this Section with respect to such greater amount of 
Shares.

          (c)  EXEMPTIONS.    The provisions of this Section shall not apply to
(i) any issuance and sale of Shares by Parent in a Demand Registration (as
defined in Annex A) or in a Piggy-back Registration (as defined in Annex A) in
which the Investor is participating; (ii) the grant or exercise of employee,
management or director stock options to purchase Shares pursuant to, or the
issuance of Shares otherwise under or pursuant to, the Parent Share Issuance
Commitments; (iii) any grant or exercise of employee, management or director
stock options not included in the Parent Share Issuance Commitments the grant of
which, when aggregated with options or Shares included in or issued under the
Parent Share Issuance Commitments, was or is consistent with CSC's and Parent's
past practices; (iv) any sale, grant or issuance of Shares that, together with
any previous sales, grants or issuances made in reliance on this clause (iv),
represents less than 1% of the Outstanding Share Capital as of the date of such
sale, grant or issuance; and (v) any other sale, grant or issuance of Shares
that has been approved in writing by the Investor.

          (d)  NON-CASH VALUATION.  In the event that any offer, issue, grant or
sale includes or is proposed to include any non-cash consideration, Parent and
the Investor shall in good faith seek to agree upon the value of such non-cash
consideration.  If Parent and the Investor fail to agree on such value during
the 15-day period contemplated by paragraph (a) of this Section, then Parent
shall refer the items in dispute to a nationally recognized investment banking
firm that is selected by the Board and that shall make a final and binding
determination within 10 days.  The value of any securities shall be the fair
market value of such securities and the value of any property other than
securities shall be the fair market value of such property.  


                                     -21-
<PAGE>

If a determination under this paragraph (d) is required, any deadline for 
acceptance provided for in this Section shall be postponed until the fifth 
business day after the date of such determination.  Whichever of the Investor 
or Parent whose last estimate differed the most from that finally decided by 
the investment banking firm shall be responsible for and pay all of the 
expenses of such investment banking firm. All determinations made pursuant to 
this paragraph (d) shall be final and binding on the Investor and Parent.

          (e)  HSR CONDITION.  If in the reasonable judgment of the Investor,
the Investor's acquisition of Shares upon exercise of its rights under this
Section 10 would require a filing under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), Parent and the Investor
each will take such actions as may be required promptly to comply with the
requirements of the HSR Act relating to the filing and furnishing of information
(an "HSR Report") to the Federal Trade Commission ("FTC") and the Antitrust
Division of the Department of Justice ("DOJ"), such actions to include
(i) preparing and cooperating with each other in preparing the HSR Report to be
filed by or on behalf of each of them so as to avoid errors or inconsistencies
between their HSR Reports in the description of the reported transaction and to
permit the filing of their HSR Reports in a timely fashion, (ii) complying with
any request for additional documents or information made by the FTC, the DOJ or
any other Governmental Entity or by any court and assisting the other in so
complying and (iii) causing all Persons which are part of the same "person" (as
defined for purposes of the HSR Act) as such party to cooperate and assist in
such compliance.  Parent and the Investor each will pay any costs that it incurs
in complying with the obligations set forth in this paragraph.  It will be a
condition precedent to the acquisition of Shares by the Investor that either
(i) no filing under the HSR Act by the Investor is required in connection with
such acquisition or (ii) any applicable waiting period under the HSR Act has
expired or been terminated.  If the applicable waiting period under the HSR Act
has not expired or been terminated within 180 days after filing of the HSR
Report or if the Investor and Parent agree to withdraw the HSR Report, then
Parent will use its reasonable best efforts to afford to the Investor the
benefits intended to be provided by this Section 10 by granting to the Investor
the right to acquire,  on the same terms as the securities originally to be
acquired, other securities of Parent having substantially 


                                     -22-
<PAGE>

the same rights, privileges and preferences as the securities originally to 
be acquired, except that such other securities will not possess voting rights 
and will be convertible into the Shares that the Investor was to acquire 
pursuant to this Section.

          11.  BOARD REPRESENTATION.  

          (a)  INVESTOR DIRECTORS.  For so long as, and only for so long as, the
Investor Beneficially Owns Parent Class A Shares that in the aggregate comprise
at least 20% of the Outstanding Share Capital, the Investor shall be entitled to
nominate two and no more than two directors (the "Investor Directors") to the
Board, each of whom shall be a person that is reasonably acceptable to Parent
(it being agreed for this purpose that, subject to applicable legal
requirements,  any executive officer or member of the board of directors of the
Company shall be acceptable to Parent); PROVIDED, that in the event that the
Investor shall at any time cease to Beneficially Own Parent Class A Shares that
in the aggregate comprise at least 20% of the Outstanding Share Capital but
shall continue to Beneficially Own Parent Class A Shares that in the aggregate
comprise at least 10% of the Outstanding Share Capital, the Investor shall
thenceforth be entitled to nominate one and no more than one Investor Director
under this Section 11 and Parent or any of the Class B Entities may request that
one of the Investor Directors then on the Board resign as a director of Parent
and, upon such request, one of the Investor Directors shall, and the Investor
shall use best efforts to cause one of the Investor Directors to, resign
immediately and relinquish all rights and privileges as a member of the Board;
PROVIDED, FURTHER, that each of the Investor Directors shall in all cases be a
director elected to the Board by the Parent Class B Shares.  In the event that
the Investor shall at any time cease to Beneficially Own Parent Class A Shares
that in the aggregate comprise at least 10% of the Outstanding Share Capital,
the Investor shall thenceforth not be entitled to nominate any Investor
Directors under this Section 11 and Parent or any of the Class B Entities may
request that any Investor Directors then on the Board resign as directors of
Parent and, upon such request, the Investor Directors shall, and the Investor
shall use its reasonable best efforts to, cause such Investor Directors to,
resign immediately and relinquish all rights and privileges as a member of the
Board. 


                                     -23-
<PAGE>

          Prior to the election of directors to the Board, the Investor may give
reasonable advance written notice to Parent prior to the mailing of the proxy
statement relating to such matters requesting that Parent include, and Parent
and the Class B Entities (in their capacity as stockholders of Parent) agree
that Parent shall include, the Investor Directors as nominees for the slate of
directors to be elected to the Board.  

          Notwithstanding the foregoing, in the event that the holders of the
Class B Shares cease at any time to be entitled to elect 75% of the Board in
accordance with the terms of the Parent Class B Shares, the Investor shall
thenceforth no longer be entitled to any rights under this Section and the
Investor agrees that, following such event, Parent may request that all or any
of the Investor Directors then on the Board resign as Investor Directors, and
upon such request by Parent, the Investor Directors shall, and the Investor
shall use reasonable best efforts to cause such Investor Directors to, resign as
Investor Directors and relinquish all rights and privileges as a member of the
Board at the next meeting of stockholders of Parent called for the purpose of
electing directors to the Board; PROVIDED, that such Investor Directors may in
any case be nominees as directors to the Board at any meetings called for
election of directors in accordance with this Agreement and with the By-laws of
Parent.  Notwithstanding anything to the contrary in this Agreement, no more
than 25% of the directors on the Board (rounded up to the nearest whole
director) shall be nominees of the Investor or any Affiliate or Associate of the
Investor.     

          (b) SPECIAL COMMITTEE.  For so long as, and only for so long as, the
Investor is entitled to nominate two Investor Directors pursuant to Section
11(a) (without giving effect to any reduction in the number of Investor
Directors resulting from the last sentence of Section 11(a)), (i) two (or one,
if the number of Investor Directors is reduced as a result of Section 11(a)) of
the Special Directors shall be the Investor Directors and (ii) Section 9 of
Article II of Parent's By-laws may not be amended without the prior written
consent of the Investor.  If only one of the Special Directors is an Investor
Director as a result of any reduction resulting from the last sentence of
Section 11(a), then any matter requiring the approval of the Special Directors
shall not be approved without the approval of the Investor Director.  The
Investor, Parent and the Class B Entities agree that the Investor Directors
shall not be 


                                     -24-
<PAGE>

entitled to vote on the transactions contemplated by the Partnership 
Contribution or on the approval or adoption of the Partnership Contribution 
Agreement notwithstanding the fact that such transaction and such agreement 
may be referred to the Special Committee.

          (c)  EFFORTS TO NOMINATE AND ELECT DIRECTORS.  Parent shall nominate
and Parent and the Class B Entities shall use their respective best efforts to
take and cause to be taken all necessary action (corporate and other), which
efforts shall include the voting of or granting consents with respect to all
Voting Securities of Parent Beneficially Owned by them, to elect to the Board
the Investor Directors required to be nominated for election as directors in
accordance with the terms of this Section.

          12.  INVESTOR VOTING.  For so long as the Class B Shares are entitled
in accordance with their terms to elect 75% of the Board, with respect to the
election of directors to or removal of directors from the Board and any increase
of authorized Shares, the Investor shall vote or grant consent with respect to,
and shall cause to be voted or to be granted any consents with respect to, all
Voting Securities that are Beneficially Owned by the Investor on all matters
submitted to the holders of Voting Securities in direct proportion to the votes
or consents of the Minority Shares on any such matter.  The Investor and the
Class B Entities shall cause all Shares owned by the Investor and the Class B
Entities, as the case may be, and shall use reasonable best efforts to cause all
of their respective Affiliates and Associates to be represented, in person or by
proxy, at all meetings of holders of Shares of which the Investor or the Class B
Entities, as the case may be, have actual notice, so that all of such Shares may
be counted for the purpose of determining the presence of a quorum at such
meetings.

          13. ACQUISITION TRANSACTIONS.  For so long as, and only for so long
as, the Investor is entitled to nominate two Investor Directors pursuant to
Section 11(a), Parent shall not, without the prior written consent of the
Company, consummate an Acquisition Transaction if, after giving effect to such
transaction, the Cash Flow Ratio will exceed the Cash Flow Ratio Threshold. 
Before consummation of an Acquisition Transaction that is reasonably likely to
result in the Cash Flow Ratio Threshold being exceeded, Parent shall provide
written notice and a reasonable description of such transaction, including pro
forma calculations of the 


                                     -25-
<PAGE>

Cash Flow Ratio giving effect to such transaction as of the beginning of the 
most recent three-month period for which Annualized Operating Cash Flow can 
be calculated, together with reasonable documentary supporting information 
for such calculation.  To the extent reasonably practicable under the 
circumstances of such transaction, such notice shall be given 30 days prior 
to such consummation, but in no event shall such notice be given less than 10 
days prior to such consummation.

          14.  ADDITIONAL AGREEMENTS.  

          (a)  EXCHANGE ACT REPORTING.  For so long as, and only for so long as,
any of the Shares Beneficially Owned by the Investor are "restricted securities"
within the meaning of Rule 144(a)(3) under the Securities Act, unless Parent is
then subject to and in compliance with Section 13 or 15(d) of the Exchange Act
as contemplated by Rule 144(c)(1) under the Securities Act, Parent shall make
publicly available any information concerning Parent that is contemplated by
Rule 144(c)(2) under the Securities Act.

          (b)  MAINTENANCE OF ULTIMATE PARENT ENTITY AS A PARTY.  In the event
that the Company shall at any time become or be a Subsidiary of any Person that
is not a natural person, the Company covenants and agrees that the Ultimate
Parent Entity of such Person shall forthwith execute a counterpart of this
Agreement and shall assume all obligations of the Company hereunder and all
references herein to the Company shall be deemed a reference to such Ultimate
Parent Entity.  This paragraph shall similarly apply to any subsequent Ultimate
Parent Entities.

          (c)  REGISTRATION RIGHTS.  The Investor shall have the registration
rights set forth in Annex A hereto.   

          (d)  VOLUME DISCOUNTS.  The Company shall use its reasonable best
efforts to make available to Parent and its Subsidiaries the benefits of its
agreements with vendors on terms no less favorable than those generally
available to the Company or Affiliates of the Company.

          15.   LEGENDS.  (a) Each of the Investor and the Class B Entities
agrees that all certificates representing the Shares that are from time to time
subject to this Agreement shall bear the following legend:


                                     -26-
<PAGE>

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A
     STOCKHOLDERS AGREEMENT DATED MARCH 4, 1998(A COPY OF WHICH IS ON FILE
     WITH THE SECRETARY OF THE CORPORATION) WHICH PROVIDES, AMONG OTHER
     THINGS, FOR CERTAIN RESTRICTIONS ON THE TRANSFER AND VOTING THEREOF. 
     THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD OR
     OTHERWISE TRANSFERRED EXCEPT IN COMPLIANCE WITH SAID AGREEMENT.  ANY
     SALE OR OTHER TRANSFER NOT IN COMPLIANCE WITH SAID AGREEMENT SHALL BE
     VOID."

Upon termination with respect to the Investor or the Class B Entities of this
Agreement in accordance with its terms or upon any Shares ceasing to be subject
to this Agreement and upon the written request by the Investor or any of the
Class B Entities, as the case may be, Parent shall issue new certificates with
the foregoing legend removed.

          (b)  The Investor agrees that all certificates representing the Shares
that were issued in the Contribution and that are Transferred pursuant to this
Agreement (unless a registration statement with respect to such Shares is then
effective) shall bear the following legend until such time as the Investor or
any transferee thereof delivers an opinion of counsel reasonably acceptable to
Parent to the effect that such legend is no longer required under the Securities
Act:

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE SOLD WITHOUT
          REGISTRATION UNDER THE SECURITIES ACT OF 1933 AND MAY BE OFFERED
          OR SOLD ONLY IF REGISTERED UNDER THE SECURITIES ACT OF 1933 OR IF
          AN EXEMPTION FROM REGISTRATION IS AVAILABLE."

          16.  MISCELLANEOUS.

          (a)  GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH AND
SUBJECT TO THE LAWS OF THE STATE OF DELAWARE, WITHOUT REFERENCE TO CONFLICTS OF
LAWS PRINCIPLES.

          (b)  VENUE; WAIVER OF JURY TRIAL.  The parties hereby irrevocably
submit to the jurisdiction of the courts of the State of Delaware and the
Federal court of the United States of America located in the State of Delaware
solely in 


                                     -27-
<PAGE>

respect of the interpretation and enforcement of the provisions of this 
Agreement and of the documents referred to in this Agreement, and in respect 
of the transactions contemplated hereby, and hereby waive, and agree not to 
assert, as a defense in any action, suit or proceeding for the interpretation 
or enforcement hereof or of any such document, that it is not subject thereto 
or that such action, suit or proceeding may not be brought or is not 
maintainable in said courts or that the venue thereof may not be appropriate 
or that this Agreement or any such document may not be enforced in or by such 
courts, and the parties hereto irrevocably agree that all claims with respect 
to such action or proceeding shall be heard and determined in such a Delaware 
State or Federal court.  The parties hereby consent to and grant any such 
court jurisdiction over the person of such parties and over the subject 
matter of such dispute and agree that mailing of process or other papers in 
connection with any such action or proceeding in the manner provided in 
paragraph (c) of this Section or in such other manner as may be permitted by 
law shall be valid and sufficient service thereof. 

          EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY
ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT
ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY

LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT,
OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.  EACH PARTY CERTIFIES AND
ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY

EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY
UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY
MAKES THIS WAIVER VOLUNTARILY, AND (iv) EACH PARTY HAS BEEN INDUCED TO ENTER
INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS PARAGRAPH (b).

          (d)  SEVERABILITY.  The provisions of this Agreement shall be deemed
severable and the invalidity or unenforceability of any provision shall not
affect the validity or enforceability of the other provisions hereof.  If any
provision of this Agreement, or the application thereof to any Person or any
circumstance, is invalid or unenforceable, (i) a suitable and equitable
provision shall be substituted therefor in order to carry out, so far as may be
valid and enforceable, the intent and purpose of such invalid or unenforceable
provision and (ii) the remainder of this Agreement and the application of such
provision to other Persons or circumstances shall not be affected by such
invalidity or unenforceability, nor shall such invalidity or unenforceability
affect the validity or enforceability of such provision, or the application
thereof, in any other jurisdiction.

          (e)  COUNTERPARTS.  For the convenience of the parties hereto, this
Agreement may be executed in any number of counterparts, each of which shall be
deemed to be an original and all of which shall together constitute the same
agreement.


                                     -30-
<PAGE>

          (f)  TERMINATION; SURVIVAL.  Immediately upon the Investor, together
with all of the Affiliates of the Investor, ceasing to Beneficially Own in the
aggregate at least 20% of the Outstanding Share Capital, Sections 7 and 9 shall
terminate automatically without any action by any party and such terminated
provision shall not survive such termination.  Immediately upon the Investor,
together with all of the Affiliates of the Investor, ceasing to Beneficially Own
in the aggregate at least 10% of the Outstanding Share Capital, this Agreement
(other than Sections 1, 2, 3, 4, 5, 14(c), 15 and 16) shall terminate
automatically without any action by any party and such terminated provisions of
this Agreement shall not survive such termination.  On the day that is two years
after the date of such termination, Section 5 shall terminate automatically
without any action by any party and shall not survive such termination. 
Immediately upon a Transfer to a Permitted Transferee pursuant to Section 6(h),
Sections 7, 9, 11(b) and 13 shall terminate automatically without any action by
any party and such terminated provisions of this Agreement shall not survive
such termination; PROVIDED, that if such Permitted Transferee is a Competitor,
all of Section 11 shall terminate automatically without any action by any party
and such terminated provision shall not survive such termination; PROVIDED,
FURTHER, that on the day that is five years following a Transfer to any such
Permitted Transferee, Section 10 shall terminate automatically without any
action by any party and such terminated provision shall not survive such
termination.  This Section 16 and Sections 1, 2, 3, 4, 14(c) and 15 shall
survive any termination of all or any part of this Agreement indefinitely.

          (g)  HEADINGS; RECITALS.  All Section headings and the recitals herein
are for convenience of reference only and are not part of this Agreement, and no
construction or reference shall be derived therefrom.

          (h)  SPECIFIC PERFORMANCE.  Each party hereto acknowledges that it
will be impossible to measure in money the damage to the other party if a party
hereto fails to comply with any of the obligations imposed by this Agreement,
that every such obligation is material and that, in the event of any such
failure, the other party will not have an adequate remedy at law or damages. 
Accordingly, each party hereto agrees that injunctive relief or other equitable
remedy, in addition to remedies at law or damages, is the appropriate remedy for
any such failure and will not oppose the granting of such relief on the basis
that the 


                                     -31-
<PAGE>

other party has an adequate remedy at law.  Each party hereto agrees that it 
shall not seek, and agrees to waive any requirement for, the securing or 
posting of a bond in connection with any other party's seeking or obtaining 
such equitable relief.

          (i)  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
permitted assigns and shall not be assignable except to the extent expressly
permitted hereby and any purported assignment in violation of this Agreement
shall be void.  Any Class B Entity may assign this Agreement in connection with
a Transfer of any Shares to a Class B Entity or any Qualified Parties or
Controlled Subsidiaries of any Class B Entities; PROVIDED, that such transferee
shall become a party to a counterpart of this Agreement and become bound as a
Class B Entity hereunder.  In the case of a merger or other business combination
or reorganization transaction involving Parent where securities other than those
of Parent are issued to the holders of Shares, this Agreement shall be assigned
to and shall inure to the benefit of and be binding upon the Person issuing
securities in such transaction and any reference herein to Parent shall be
deemed to be a reference to such Person.  The rights and obligations under this
Agreement (excluding Sections 7, 9, 11(b) and 13) shall be assigned by the
Investor and the Company to a Permitted Transferee in connection with the
Transfer to such Permitted Transferee pursuant to Section 6(h); PROVIDED, that
if such Permitted Transferee is a Competitor, Section 11 shall also be excluded
from such assignment, which assignment shall not terminate any portion of this
Agreement except in accordance with Section 16(f).  The Investor may assign its
rights and obligations (w) under this Agreement to a Permitted Transferee
pursuant to Section 6(a)(i), (x) under this Agreement to a Permitted Transferee
pursuant to Section 6(a)(ii), (y) under Sections 14(c), 15 and 16 to a
transferee pursuant to Section 6(b) and (z) under Sections 6, 11, 14(c), 15 and
16 to a transferee pursuant to Section 6(g), which assignment shall not
terminate any obligations of the Investor hereunder; PROVIDED, that in the event
of an assignment described in (x), (y) or (z) above, the Investor agrees with
Parent that the transferee(s) and the Investor shall, with respect to Parent,
act as one Investor under such assigned Sections.

          (j)  ENTIRE AGREEMENT; AMENDMENT; WAIVER.  This Agreement (including
any annexes and schedules hereto) and 


                                     -32-
<PAGE>

the Merger Agreement (including any exhibits and schedules thereto) supersede 
all prior agreements, written or oral, among the parties hereto with respect 
to the subject matter hereof and contains the entire agreement among the 
parties with respect to the subject matter hereof.  This Agreement may not be 
amended, supplemented or modified, and no provisions hereof may be modified 
or waived, except by an instrument in writing signed by the party or parties 
affected or to be affected thereby.  No waiver of any provisions hereof by 
any party shall be deemed a waiver of any other provisions hereof by any such 
party, nor shall any such waiver be deemed a continuing waiver of any 
provision hereof by such party.

          (k)  NO REQUEST FOR AMENDMENT OR WAIVER.  The Company shall not, and
shall cause its Affiliates not to and use reasonable best efforts to cause its
Associates not to, request publicly that Parent or any of the Class B Entities
or any of their respective agents or representatives, directly or indirectly,
amend or waive any provision of this Agreement or make any such request
privately if it could reasonably be expected to require Parent to make a public
announcement regarding such request.

          (l)  NO RELIEF OF LIABILITIES.  No Transfer by the Investor or any
Class B Entity of Beneficial Ownership of any Shares shall relieve the Investor
or such Class B Entity of any liabilities or obligations to Parent or to a
Class B Entity (in the case of a Transfer by the Investor) or to the Investor
(in the case of a Transfer by a Class B Entity) that arose or accrued prior to
the date of such Transfer.

          (m)  SECURITIES SUBJECT TO AGREEMENT; INEFFECTIVE TRANSFERS.  All
Shares that are Beneficially Owned by the Investor (including any Shares
disclosed pursuant to Section 2(a) for as long as such Shares are Beneficially
Owned by the Investor or its Affiliates), and the Class B Entities and, to the
extent provided herein, the Affiliates and Associates of the Investor and the
Class B Entities, shall be subject to this Agreement.  No Transfer or
acquisition of any Shares in violation of any provision of this Agreement shall
be effective to pass any title to, or create any interest in favor of, any
Person, but the Investor or Class B Entities, as the case may be, in attempting
to effect or in permitting or suffering such Transfer or acquisition, shall be
deemed to have committed a material breach hereof.


                                     -33-
<PAGE>

          (n)  FURTHER ASSURANCES.  The parties hereto shall execute and deliver
such additional instruments and other documents and shall take such further
actions as may be necessary or appropriate to effectuate, carry out and comply
with all of the terms of this Agreement and the transactions contemplated
hereby.

          (o)  THIRD PARTY BENEFICIARIES.  NOTHING IN THIS AGREEMENT, EXPRESS OR
IMPLIED, IS INTENDED TO CONFER UPON ANY THIRD PARTY ANY RIGHTS OR REMEDIES OF
ANY NATURE WHATSOEVER UNDER OR BY REASON OF THIS AGREEMENT.

                                 REGISTRATION RIGHTS

     The Parent Class A Shares that are Beneficially Owned by the Investor from
time to time are hereinafter referred to as the "Registrable Securities" and
shall have the benefit of the following registration rights.

Demand
Registration:       After the date that is six months following the Contribution
                    Closing, the Investor may request, by written notice to
                    Parent, that Parent file a registration statement
                    registering for offering and sale Registrable Securities in
                    an amount equal to or in excess of 2,000,000 Shares or, if
                    less, the Shares then Beneficially Owned by the Investor and
                    any transferees with rights hereunder in an underwritten
                    public offering (a "Demand Registration").  Parent will use
                    its reasonable best efforts to file a registration statement
                    on an appropriate form with the SEC covering the Registrable
                    Securities for which registration was so requested within
                    30 days of Parent's receipt of such request, subject to
                    Parent's blackout rights described below, and shall use its
                    reasonable best efforts to cause such registration statement
                    to be declared effective as soon thereafter as practicable. 
                    In addition, Parent shall amend or supplement such
                    registration statement so that the Investor may use such
                    registration statement and the related prospectus in
                    connection with an underwritten offering of such Registrable
                    Securities for 90 days from the effective date of such
                    registration statement, subject to Parent's blackout rights
                    described below.  Parent agrees to keep the Demand
                    Registration effective for such 90-day period and, after the
                    expiration of such 90-day period, may deregister the
                    Registrable 

                                          A-1
<PAGE>

                    Securities registered thereon.  Parent shall not
                    be obligated to effect more than one Demand Registration for
                    the Investor in each of the years following the date that is
                    six months following the Contribution Closing.

Piggy-back
Registration:       The Investor shall be entitled to "piggy-back" registration
                    rights on any registrations of Shares registering for
                    offering and sale at least $100 million of Shares (based
                    upon the market value thereof on the date of filing), other
                    than a registration on Form S-8, Form S-4 or any successors
                    to such forms (a "Piggy-back Registration"), subject to the
                    cutback provisions described below.

Registration
Expenses:           The Investor will pay a proportional amount (based upon the
                    number of shares registered by the Investor) of any and all
                    fees and expenses in a Piggy-back Registration; PROVIDED,
                    that the Investor will not be responsible for counsel
                    expenses of other selling stockholders.  In a Demand
                    Registration, Parent will pay any and all fees and expenses;
                    PROVIDED that Parent will not be responsible for the counsel
                    expenses of the Investor or any underwriting fees and
                    commissions for the Shares sold by the Investor.

Underwriters:       In case of any Demand Registration or Piggy-back
                    Registration, Parent shall select the underwriter or
                    underwriters that shall manage or lead such registration. 
                    The Investor shall not be entitled to participate in any
                    underwritten offering unless and until the Investor has
                    entered into an underwriting or other agreement with such
                    underwriter or underwriters in such form as Parent and such
                    underwriter or underwriters shall determine.

                    In addition, in connection with any underwritten offering
                    proposed by the Investor hereunder, Parent shall enter into
                    an underwriting or other agreement with the underwriters
                    thereof containing customary representations, warranties,
                    covenants, indemnities and other terms.

Transfer of
Registration
Rights:             The Investor may transfer or assign its registration rights
                    in connection with any Transfer of Registrable Securities to
                    a Permitted Transferee or a transferee under Section 6(b) or
                    6(g); PROVIDED, that any such transferee shall agree to be
                    bound by the terms hereof relating to Shares or securities
                    convertible or exchangeable for Shares and, with respect to
                    Parent, all of such transferees must act as one Investor
                    hereunder.

Lock-Up Provision:  The Investor will not engage in transactions involving
                    Parent's equity securities, including by commencing any
                    public offering of Parent's equity securities or by causing
                    a Demand Registration, for a period not to exceed 180 days
                    after the effective date of any Parent registration
                    statement that is equal to the shortest period that such
                    restriction is made applicable to any director, officer or
                    Affiliate of Parent.

Blackout Rights:    Upon written notice to the Investor, Parent may suspend the
                    Investor's right to sell Registrable Securities under a
                    registration statement or temporarily refuse to proceed with
                    a Demand Registration under the following circumstances: (a)
                    Parent reasonably believes that the use of such registration
                    statement would require disclosure of a material corporate
                    development not otherwise required to be disclosed that
                    Parent has a valid 

                                            A-3
<PAGE>

                    business purpose for not disclosing, (b) Parent is in 
                    the process of making, or preparing to make, a registered 
                    offering of securities and Parent reasonably deems it 
                    advisable to temporarily discontinue disposition of
                    Registrable Securities or (c) Parent reasonably believes
                    that disposition of Registrable Securities at such time
                    would have a material adverse effect on Parent.  Parent
                    shall notify the Investor immediately upon the conditions in
                    clause (a) or (c) above ceasing to exist, at which time such
                    suspension shall terminate.  Notwithstanding the foregoing,
                    (i) the maximum period in which Parent can suspend the
                    Investor's rights under clauses (a), (b) and (c) above is 60
                    days on any single occasion and 145 consecutive days in any
                    one-year period, (ii) Parent may not suspend such rights
                    more than three times in any one-year period commencing
                    after the date that the Demand Registration becomes
                    effective and (iii) the Investor shall in any event, taking
                    into account the blackout rights and lock-up provisions set
                    forth herein, be entitled to 180 days in any one-year period
                    (other than the period prior to the date that is six months
                    following the Stock Closing) that are not subject to any
                    blackout or lock-up.  The Investor's rights hereunder may
                    not be suspended unless corresponding rights of other
                    stockholders are similarly suspended.

Cutback Rights:     In the event that the Investor, Parent and/or any
                    stockholder or Affiliate of Parent are participating in an
                    underwritten equity offering and the managing or lead
                    underwriter or underwriters thereof shall determine in its
                    or their reasonable good faith judgment that it cannot sell,
                    or that it would not be advisable to sell, all the Shares
                    desired to be sold, then the number of Shares that each such
                    Person 

                                                 A-4
<PAGE>

                    may have included shall be reduced according to the
                    following terms until the managing or lead underwriter or
                    underwriters shall believe that the remaining Shares can be
                    sold and it would not be inadvisable to sell such number of
                    Shares:

                              (a) in the event that the offering in question
                         includes a primary offering of Shares by Parent, then
                         the number of Shares that Parent may have included
                         shall not be reduced and the number of Shares which the
                         Investor and any other Persons may have included shall
                         be reduced pro rata in proportion to the total number
                         of Shares sought to be included by each such Person,
                         and

                              (b) in the event that the offering in question
                         does not include a primary offering of Shares by
                         Parent, then the number of shares that the Investor and
                         any other Persons may have included shall be reduced
                         pro rata in proportion to the total number of Shares
                         sought to be included by each such Person.

Indemnification:    Parent will indemnify the Investor and the Investor's
                    officers, directors and controlling persons against any
                    losses, claims, damages, expenses or liabilities incurred by
                    the Investor arising out of, or based upon, any untrue
                    statement or alleged untrue statement of a material fact
                    contained in any registration statement or prospectus or
                    amendment or supplement thereto, including any document
                    incorporated by reference therein, or the omission or
                    alleged omission therefrom of a material fact necessary in
                    order to make the statements therein, in light of the
                    circumstances under which they were

                    made, not misleading; PROVIDED, that Parent shall not be 
                    liable to the extent that any loss, claim, damage, 
                    expense or liability arises out of information supplied 
                    in writing by the Investor or any of its Affiliates or 
                    Associates for use in any registration statement or 
                    prospectus or amendment or supplement thereto, including 
                    any document incorporated by reference therein. The 
                    Investor shall indemnify Parent and Parent's officers, 
                    directors and controlling persons against any losses, 
                    claims, damages, expenses or liabilities incurred by 
                    Parent arising out of, or based upon, any untrue 
                    statement or alleged untrue statement of a material fact 
                    relating to the Investor contained in any registration 
                    statement or prospectus or amendment or supplement 
                    thereto, including any document incorporated by reference 
                    therein, which information was supplied in writing by the 
                    Investor or any of its Affiliates or Associates for use 
                    in any registration statement or prospectus or amendment 
                    or supplement thereto, or the omission or alleged 
                    omission therefrom of a material fact relating to the 
                    Investor necessary in order to make the statements 
                    therein, in light of the circumstances under which they 
                    were made, not misleading.  

                    Promptly after receipt by an indemnified party under the
                    preceding paragraph of notice of the commencement of any
                    action, such indemnified party shall, if a claim in respect
                    thereof is to be made against the indemnifying party under
                    such paragraph, notify the indemnifying party in writing of
                    the commencement thereof; but the omission so to notify 

                                             A-6

<PAGE>

                    the indemnifying party shall not relieve it from any 
                    liability which it may have to any indemnified party 
                    otherwise than under such subsection.  In case any such 
                    action shall be brought against any indemnified party and 
                    it shall notify the indemnifying party of the 
                    commencement thereof, the indemnifying party shall be 
                    entitled to participate therein and, to the extent that 
                    it shall wish, jointly with any other indemnifying party 
                    similarly notified, to assume the defense thereof, with 
                    counsel satisfactory to such indemnified party (who shall 
                    not, except with the consent of the indemnified party, be 
                    counsel to the indemnifying party), and, after notice 
                    from the indemnifying party to such indemnified party of 
                    its election so to assume the defense thereof, the 
                    indemnifying party shall not be liable to such 
                    indemnified party under such subsection for any legal 
                    expenses of other counsel or any other expenses, in each 
                    case subsequently incurred by such indemnified party, in 
                    connection with the defense thereof other than reasonable 
                    costs of investigation.  No indemnifying party shall, 
                    without the written consent of the indemnified party, 
                    effect the settlement or compromise of, or consent to the 
                    entry of any judgment with respect to, any pending or 
                    threatened action or claim in respect of which 
                    indemnification or contribution may be sought hereunder 
                    (whether or not the indemnified party is an actual or 
                    potential party to such action or claim) unless such 
                    settlement, compromise or judgment (i) includes an 
                    unconditional release of the indemnified party from all 
                    liability arising out of such action or claim and (ii) 
                    does not include a statement as to or an admission of 
                    fault, culpability or a failure to act by or on behalf of 
                    any indemnified party.

                    list the shares on the principal securities exchanges or
                    markets on which or in which the outstanding securities of
                    the same class are listed or traded, (ii) obtain any
                    required clearance with state securities regulators, (iii)
                    file Exchange Act reports on a timely basis, (iv) make

                    times, (v) participate in a reasonable number of management
                    due diligence sessions at reasonable times (but Parent's

                    metropolitan area in which its principal executive offices
                    are located) and (vi) furnish copies of required
                    prospectuses, in each case, at the expense of the Investor.

                    respects to the rights granted to Cablevision Systems
