     The STRYPES will be payable at maturity or upon redemption by delivery of
shares of Class A Common Stock, par value $1.00 per share (the "Cox Common
Stock"), of Cox Communications, Inc., a Delaware corporation ("Cox"), subject to
the Company's option to deliver at maturity, in lieu of shares of Cox Common
Stock, cash with an equal value.  The Company, Cox and the Underwriter are
concurrently entering into an agreement dated the date hereof (the "Registration
Agreement") relating to the registration of shares of Cox Common Stock
deliverable by the Company pursuant to the STRYPES.

     The Company understands that the Underwriter proposes to make a public
offering of the Securities as soon as the Underwriter deems advisable after this
Agreement has been executed and delivered.

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 33-65135) for the
registration of debt securities, including the Securities, and warrants under
the Securities Act of 1933, as amended (the "1933 Act"), and the offering
thereof from time to time in accordance with Rule 415 of the rules and
regulations of the Commission under the 1933 Act (the "1933 Act Regulations"),
and the Company has filed post-effective amendment no. 1 thereto, including a
preliminary prospectus and preliminary prospectus supplement relating to the
offering of the Securities.  Promptly after execution and delivery of this
Agreement, the Company will either (i) prepare and file a prospectus and
prospectus supplement in accordance with the provisions of Rule 430A ("Rule
430A") of the 1933 Act Regulations and paragraph (b) of Rule 424 ("Rule 424(b)")
of the 1933 Act Regulations or (ii) if the Company has elected to rely upon Rule
434 ("Rule 434") of the 1933 Act Regulations, prepare and file a term sheet (an
"ML&Co. Term Sheet") in accordance with the provisions of Rule 434 and Rule
424(b).  The information included in such prospectus and prospectus supplement
or in such ML&Co. Term Sheet, as the case may be, that was omitted from such
registration statement (as so amended) at the time it became effective but that
is deemed to be part of such registration statement (as so amended) at the time
it became effective (i) pursuant to paragraph (b) of Rule 430A is referred to as
"Rule 430A Information" or (ii) pursuant to paragraph (d) of Rule 434 is
referred to as "Rule 434 Information."  Any prospectus and prospectus supplement

after such effectiveness and prior to the execution and delivery of this
Agreement, in each case excluding any Cox preliminary prospectus (as defined
below) attached as Appendix A thereto, are herein called, collectively, an
"ML&Co. preliminary prospectus."  Such registration statement (as so amended),
including the exhibits thereto, the schedules thereto, if any, and the documents
incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933
Act, at the time it became effective and including the Rule 430A Information and
the Rule 434 Information, as applicable, is herein called the "ML&Co.
Registration Statement."  Any registration statement filed by the Company
pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the
"ML&Co. Rule 462(b) Registration Statement," and after such filing the term
"ML&Co. Registration Statement" shall include the ML&Co. Rule 462(b)
Registration Statement.  The final prospectus and final prospectus supplement

Act, but excluding any Cox Prospectus (as defined below) attached as Appendix A
thereto, in the form first furnished to the Underwriter for use in connection
with the offering of the Securities are collectively referred to herein as the
"ML&Co. Prospectus."  If Rule 434 is relied on, the term "ML&Co. Prospectus"
shall refer to the ML&Co. preliminary prospectus dated May 8, 1996 together with
the ML&Co. Term Sheet and all references in this Agreement to the date of the
ML&Co. Prospectus shall mean the date of the ML&Co. Term Sheet.  For purposes of
this Agreement, all references to the ML&Co. Registration Statement, any ML&Co.
preliminary prospectus, the ML&Co. Prospectus or any ML&Co. Term Sheet or any
amendment or supplement to any of the foregoing shall be deemed to include the
copy filed with the Commission pursuant to its Electronic Data Gathering,
Analysis and Retrieval system ("EDGAR").
 
     All references in this Agreement to financial statements and schedules and
other information which is "contained," "included" or "stated" in the ML&Co.
Registration Statement, any ML&Co. preliminary prospectus or the ML&Co.
Prospectus (or other references of like import) shall be deemed to mean and
include all such financial statements and schedules and other information which
is incorporated by reference in the ML&Co. Registration Statement, any ML&Co.
preliminary prospectus or the ML&Co. Prospectus, as the case may be, and shall
be deemed to exclude all financial statements and schedules and other
information which is included or incorporated by reference in any Cox
preliminary prospectus or the Cox Prospectus which is attached as Appendix A to
any ML&Co. preliminary prospectus or the ML&Co. Prospectus; and all references
in this Agreement to amendments or supplements to the ML&Co. Registration
Statement, any ML&Co. preliminary prospectus or the ML&Co. Prospectus shall be
deemed to mean and include the filing of any document under the Securities
Exchange Act of 1934, as amended (the "1934 Act"), which is incorporated by
reference in the ML&Co. Registration Statement, such ML&Co. preliminary
prospectus or the ML&Co. Prospectus, as the case may be.

     Cox has filed with the Commission a registration statement on Form S-3 (No.
333-03351) covering the registration of (i) the shares of Cox Common Stock

sold by or on behalf of the ML&Co. Subsidiary (as defined below) under the 1933
Act, including the related preliminary prospectus or prospectuses. Each
prospectus used before such registration statement became effective is herein
called a "Cox preliminary prospectus." Such registration statement, including
the exhibits thereto, the schedules thereto, if any, and the documents
incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933

                   ------------------------                                     
     is and will be in compliance with, the provisions of that certain Florida
     act relating to disclosure of doing business with Cuba, codified as Section
     517.075 of the Florida statutes, and the rules and regulation thereunder
     (collectively, the "Cuba Act") or is exempt therefrom.

     (b) Representations and Warranties by CEI.  CEI represents and warrants to
each of the Company and the Underwriter as of the date hereof, as of the Closing
Time referred to in Section 2(c) hereof, and as of each Date of Delivery (if
any) referred to in Section 2(b) hereof, and agrees with each of the Company and
the Underwriter, as follows:

            (i)  Good Standing of CEI. CEI has been duly organized and is
                 --------------------                                    
     validly existing as a corporation in good standing under the laws of the
     State of Delaware and has corporate power and authority to enter into and
     perform its obligations under this Agreement and the STRYPES Agreement.

            (ii)  Delivery of Cox Common Stock.  At the date hereof, Cox
                  ----------------------------                          
     Holdings, Inc., a Delaware corporation and wholly-owned subsidiary of CEI,
     is the sole registered owner of and has all rights in and to at least
     14,000,000 shares of Cox Common Stock, free and clear of any security
     interest, mortgage, pledge, lien, encumbrance, claim or equity.  If
     immediately prior to maturity or redemption of the Securities CEI delivers
     to the ML&Co. Subsidiary shares of Cox Common Stock pursuant to the STRYPES
     Agreement, upon delivery by CEI to the ML&Co. Subsidiary of such shares of
     Cox Common Stock pursuant to the STRYPES Agreement, the ML&Co. Subsidiary
     will be the sole registered owner of the shares of Cox Common Stock so
     delivered and, assuming the ML&Co. Subsidiary purchased for value in good
     faith and without notice of any adverse claim, the ML&Co. Subsidiary will
     have acquired all rights in and to such shares of Cox Common Stock, free
     and clear of any security interest, mortgage, pledge, lien, encumbrance,
     claim or equity.  The delivery of shares of Cox Common Stock to the ML&Co.
     Subsidiary at maturity or upon redemption of the Securities in accordance
     with the STRYPES Agreement is not, and at the time of delivery of such
     shares will not be, subject to any right of first refusal or similar rights
     of any person pursuant to any contract to which CEI or any of its
     subsidiaries is a party or by which any of them is bound.

            (iii)  Authorization of Agreement.  This Agreement has been duly
                   --------------------------                               
     authorized, executed and delivered by CEI.

            (iv)  Authorization of the STRYPES Agreement. The STRYPES Agreement
                  --------------------------------------                       
     has been duly authorized by CEI and, at the Closing Time, will have been
     duly executed and delivered by CEI and (assuming the due authorization,
     execution and delivery by the Company and the ML&Co. Subsidiary) will
     constitute a valid and binding agreement of CEI, enforceable against CEI in
     accordance with its terms, except as the enforcement thereof may be limited
     by bankruptcy, insolvency (including, without limitation, all laws relating
     to fraudulent transfers), reorganization, moratorium or similar laws
     affecting enforcement of creditors' rights generally and except as
     enforcement thereof is subject to general principles of equity (regardless
     of whether enforcement is considered in a proceeding in equity or at law).
     Amounts received by CEI at Closing Time and at each

                                       11
<PAGE>
 
     Date of Delivery, if any, pursuant to the STRYPES Agreement will not be
     used by CEI for the purpose, whether immediate, incidental or ultimate, of
     buying or carrying a margin stock, as such terms are defined in Regulation
     G promulgated by the Board of Governors of the Federal Reserve System.

            (v)  Absence of Defaults and Conflicts. The execution, delivery and
                 ---------------------------------                             
     performance by CEI of this Agreement and the STRYPES Agreement and the
     consummation by CEI of the transactions contemplated herein and therein and
     compliance by CEI with its obligations hereunder and thereunder have been
     duly authorized by all necessary corporate action and do not and will not,
     whether with or without the giving of notice or passage of time or both,
     conflict with or constitute a breach of, or default or CEI Repayment Event
     (as defined below) under, or result in the creation or imposition of any
     lien, charge or encumbrance upon any property or assets of CEI or any of
     its subsidiaries pursuant to, any contract, indenture, mortgage, deed of
     trust, loan or credit agreement, note, lease or any other agreement or
     instrument to which CEI or any of its subsidiaries is a party or by which
     it or any of them may be bound, or to which any of the property or assets
     of CEI or any of its subsidiaries is subject (except for such conflicts,
     breaches or defaults or liens, charges or encumbrances that would not,
     singly or in the aggregate, materially and adversely affect the ability of
     CEI to perform its obligations under this Agreement  or the STRYPES
     Agreement), nor will such action result in any violation of the provisions
     of the charter or by-laws of CEI or any of its subsidiaries, or any
     applicable law, statute, rule, regulation, judgment, order, writ or decree
     of any government, government instrumentality or court, domestic or
     foreign, having jurisdiction over CEI or any of its subsidiaries or any of
     their assets, properties or operations (except for such violations that
     would not, singly or in the aggregate, materially and adversely affect the
     ability of CEI to perform its obligations under this Agreement or the
     STRYPES Agreement).  As used herein, a "CEI Repayment Event" means any
     event or condition which gives the holder of any note, debenture or other
     evidence of indebtedness (or any person acting on such holder's behalf) the
     right to require the repurchase, redemption or repayment of all or a
     portion of such indebtedness by CEI or any of its subsidiaries.

            (vi)  Absence of Further Requirements. No filing with, or
                  -------------------------------                    
     authorization, approval, consent, license, order, registration,
     qualification or decree of, any court or governmental authority or agency
     is necessary or required for the execution, delivery or performance by CEI
     of this Agreement or the STRYPES Agreement or the consummation by CEI of
     the transactions contemplated by this Agreement or the STRYPES Agreement,
     except such as have been already obtained or as may be required under the
     1933 Act or the 1933 Act Regulations or state securities laws.

            (vii)  Cox Registration Statement and Prospectus.  CEI is familiar
                   -----------------------------------------                  
     with the representations and warranties of Cox contained in Section 1(a) of
     the Registration Agreement and the information included or incorporated by
     reference in the Cox Registration Statement and the Cox Prospectus and has
     no reason to believe that (A) the representations and warranties of Cox
     contained in Section 1(a) of the Registration Agreement are not true and
     correct, (B) the Cox Registration Statement, any Cox Rule

                                       12
<PAGE>
 
     462(b) Registration Statement or any post-effective amendments thereto, at
     the respective times the Cox Registration Statement, any Cox Rule 462(b)
     Registration Statement or any post-effective amendments thereto became
     effective, contained an untrue statement of a material fact or omitted to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading or (C) the Cox Prospectus or any
     amendment or supplement thereto, at the time the Cox Prospectus was issued,
     at the time any such amended or supplemented prospectus was issued or at
     the Closing Time (and, if any Option Securities are purchased, at the Date
     of Delivery), included or will include an untrue statement of a material
     fact or omitted or will omit to state a material fact necessary in order to
     make the statements therein, in the light of the circumstances under which
     they were made, not misleading.

     (c) Officer's Certificates.  Any certificate signed by any officer of the
Company or any of its subsidiaries delivered to the Underwriter shall be deemed
a representation and warranty by the Company to the Underwriter as to the
matters covered thereby.  Any certificate signed by any officer of CEI or any of
its subsidiaries delivered to the Underwriter or the Company shall be deemed a
representation and warranty by CEI to the Underwriter or the Company, as the
case may be, as to the matters covered thereby.

     SECTION 2.  Sale and Delivery to Underwriter; Closing.

Underwriter is then exercising the option and the time and date of payment and

     The Company, subject to Section 3(a)(ii), will comply with the requirements
     of Rule 430A or Rule 434, as applicable, and will notify the Underwriter
     immediately, and confirm the notice in writing, (A) when any post-effective
     amendment to the ML&Co. Registration Statement shall become effective, or
     any supplement to the ML&Co. Prospectus or any amended ML&Co. Prospectus
     shall have been filed, (B) of the receipt of any comments from the
     Commission, (C) of any request by the Commission for any amendment to the
     ML&Co. Registration Statement or any amendment or supplement to the ML&Co.
     Prospectus or for additional information, and (D) of the issuance by the
     Commission of any stop order suspending the effectiveness of the ML&Co.
     Registration Statement or of any order preventing or suspending the use of
     any ML&Co. preliminary prospectus, or of the suspension of the
     qualification of the Securities for offering or sale in any jurisdiction,
     or of the initiation or threatening of any proceedings for any of such
     purposes.  The Company will promptly effect the filings necessary pursuant
     to Rule 424(b) and will take such steps as it deems necessary to ascertain
     promptly whether the form of prospectus transmitted for filing under Rule
     424(b) was received for filing by the Commission and, in the event that it
     was not, it will promptly file such prospectus.  The Company will use its
     best efforts to prevent the issuance of any stop order and, if any stop
     order is issued, to obtain the lifting thereof at the earliest possible
     moment.

            (ii) Filing of Amendments.   The Company will give the Underwriter
                 --------------------                                         
     notice of its intention to file or prepare any amendment to the ML&Co.
     Registration Statement (including any filing under Rule 462(b)), any ML&Co.
     Term Sheet or any amendment, supplement or revision to either the
     prospectus relating to the offering of the Securities

                                       14
<PAGE>
 
     included in the ML&Co. Registration Statement at the time it became
     effective or to the ML&Co. Prospectus, whether pursuant to the 1933 Act,
     the 1934 Act or otherwise, will furnish the Underwriter with copies of any
     such documents a reasonable amount of time prior to such proposed filing or
     use, as the case may be, and will not file or use any such document to
     which the Underwriter or counsel for the Underwriter shall reasonably
     object.

            (iii)  Delivery of ML&Co. Registration Statements.  The Company has
                   ------------------------------------------                  
     furnished or will deliver to the Underwriter, without charge, and to CEI
     and counsel for CEI signed copies of the ML&Co. Registration Statement as
     originally filed and of each amendment thereto (including exhibits filed
     therewith or incorporated by reference therein and documents incorporated
     or deemed to be incorporated by reference therein) and signed copies of all
     consents and certificates of experts.  If applicable, the copies of the
     ML&Co. Registration Statement and each amendment thereto furnished to the
     Underwriter and CEI will be identical to the electronically transmitted
     copies thereof filed with the Commission pursuant to EDGAR, except to the
     extent permitted by Regulation S-T.

            (iv) Delivery of ML&Co. Prospectuses.  The Company has delivered to
                 -------------------------------                               
     the Underwriter, without charge, as many copies of each ML&Co. preliminary
     prospectus as the Underwriter reasonably requested, and the Company hereby
     consents to the use of such copies for purposes permitted by the 1933 Act.
     The Company will furnish to the Underwriter, without charge, during the
     period when the ML&Co. Prospectus is required to be delivered under the
     1933 Act or the 1934 Act, such number of copies of the ML&Co. Prospectus
     (as amended or supplemented) as the Underwriter may reasonably request.  If
     applicable, the ML&Co. Prospectus and any amendments or supplements thereto
     furnished to the Underwriter will be identical to the electronically
     transmitted copies thereof filed with the Commission pursuant to EDGAR,
     except to the extent permitted by Regulation S-T.

            (v) Continued Compliance with Securities Laws.  The Company will
                -----------------------------------------

     the 1934 Act Regulations so as to permit the completion of the distribution
     of the Securities as contemplated in this Agreement and in the ML&Co.
     Prospectus.  If at any time when a prospectus is required by the 1933 Act
     to be delivered in connection with sales of the Securities, any event shall
     occur or condition shall exist as a result of which it is necessary, in the
     reasonable opinion of counsel for the Underwriter or for the Company, to
     amend the ML&Co. Registration Statement or amend or supplement the ML&Co.
     Prospectus in order that the ML&Co. Prospectus will not include any untrue
     statements of a material fact or omit to state a material fact necessary in
     order to make the statements therein not misleading in the light of the
     circumstances existing at the time it is delivered to a purchaser, or if it
     shall be necessary, in the reasonable opinion of either such counsel, at
     any such time to amend the ML&Co. Registration Statement or amend or
     supplement the ML&Co. Prospectus in order to comply with the requirements
     of the 1933 Act or the 1933 Act Regulations, the Company will promptly
     prepare and file with the Commission, subject to Section 3(a)(ii), such
     amendment or supplement as may be necessary to correct such statement or
     omission or to make the ML&Co. Registration Statement or the ML&Co.
     Prospectus comply with such requirements, and the Company will furnish to
     the

                                       15
<PAGE>
 
     Underwriter such number of copies of such amendment or supplement as the
     Underwriter may reasonably request.

                 -----------------------                                
     efforts, in cooperation with the Underwriter, to qualify the Securities for
     offering and sale under the applicable securities laws of such states and
     other jurisdictions of the United States as the Underwriter may designate
     and to maintain such qualifications in effect for a period of not less than
     one year from the later of the effective date of the ML&Co. Registration
     Statement and any ML&Co. Rule 462(b) Registration Statement; provided,
     however, that the Company shall not be obligated to file any general
     consent to service of process or to qualify as a foreign corporation or as
     a dealer in securities in any jurisdiction in which it is not so qualified
     or to subject itself to taxation in respect of doing business in any
     jurisdiction in which it is not otherwise so subject.  In each jurisdiction
     in which the Securities have been so qualified, the Company will file such
     statements and reports as may be required by the laws of such jurisdiction
     to continue such qualification in effect for a period of not less than one
     year from the effective date of the ML&Co. Registration Statement and any
     ML&Co. Rule 462(b) Registration Statement.

            (vii)  Rule 158.  The Company will timely file such reports pursuant
                   --------                                                     
     to the 1934 Act as are necessary in order to make generally available to
     its securityholders as soon as practicable an earnings statement for the
     purposes of, and to provide the benefits contemplated by, the last
     paragraph of Section 11(a) of the 1933 Act.

            (viii)  Use of Proceeds.  The Company will use the net proceeds
                    ---------------                                        
     received by it from the sale of the Securities in the manner specified in
     the ML&Co. Prospectus under "Supplemental Use of Proceeds."

            (ix) Listing.  The Company will use its best efforts to effect the
                 -------                                                      
     listing of the Securities on the New York Stock Exchange.

            (x) Reporting Requirements.  The Company, during the period when the
                ----------------------                                          
     ML&Co. Prospectus is required to be delivered under the 1933 Act or the
     1934 Act, will file all documents required to be filed with the Commission
     pursuant to the 1934 Act within the time periods required by the 1934 Act
     and the 1934 Act Regulations.

     (b) Covenants of CEI.

            (i) Restriction on Sale of Securities.  During a period of 120 days
                ---------------------------------                              
     from the date of this Agreement, CEI will not, without the prior written
     consent of the Underwriter, (x) offer, sell, contract to sell or otherwise
     dispose of, directly or indirectly, any shares of Cox Common Stock,
     securities convertible into, exchangeable for or repayable with shares of
     Cox Common Stock, or rights or warrants to acquire shares of Cox Common
     Stock, or (y) cause to be filed any registration statement under the 1933
     Act with respect to any shares of Cox Common Stock, securities convertible
     into, exchangeable for or repayable with shares of Cox Common Stock, or
     rights or warrants to acquire shares of Cox Common Stock.  The foregoing
     sentence shall not apply to (A) options to purchase

                                       16

     CEI existing at the date of this Agreement; or (B) shares of Cox Common

     Agreement; or (C) any transfer of shares of Cox Common Stock to an
     affiliate (as such term is defined in Rule 405 promulgated under the 1933
     Act) or affiliates of CEI, provided, however, that in any such case it
     shall be a condition to the transfer that the transferee execute an
     agreement stating that the transferee is receiving and holding such shares
     of Cox Common Stock subject to the foregoing restrictions and that there
     shall be no further transfer of such securities except in accordance

     SECTION 6.  Indemnification.
                 --------------- 

     (a) Indemnification of the Underwriter by the Company.  The Company agrees
to indemnify and hold harmless the Underwriter and each person, if any, who
controls the Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act as follows:

            (i)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in the ML&Co. Registration
     Statement (or any amendment thereto), including the Rule 430A Information
     and the Rule 434 Information, if applicable, or the omission or alleged
     omission therefrom of a material fact required to be stated therein or
     necessary to make the statements therein not misleading or arising out of
     any untrue statement or alleged untrue statement of a material fact
     contained in any ML&Co. preliminary prospectus or the ML&Co. Prospectus (or
     any amendment or supplement thereto), or the omission or alleged omission
     therefrom of a material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading;

            (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, referred to under (i) above; provided
     that (subject to Section 6(e) below) any such settlement is effected with
     the written consent of the Company; and

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

                                       24
<PAGE>
 
provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by the
Underwriter expressly for use in the ML&Co. Registration Statement (or any
amendment thereto), including the Rule 430A Information and the Rule 434
Information, if applicable, or any ML&Co. preliminary prospectus or the ML&Co.
Prospectus (or any amendment or supplement thereto).

     Insofar as this indemnity agreement may permit indemnification for
liabilities under the 1933 Act of any person who controls an underwriter within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and who,
at the date of this Agreement, is a director or officer of the Company or
controls the Company within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act, such indemnity agreement is subject to the undertaking of
the Company in the ML&Co. Registration Statement under Item 17 thereof.

     (b) Indemnification of the Underwriter and the Company by CEI.  Subject to
Section 6(f) below, CEI agrees to indemnify and hold harmless (1) the
Underwriter and each person, if any, who controls the Underwriter within the
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and (2) the
Company and each person, if any, who controls the Company within the meaning of
Section 15 of the 1933 Act or Section 20 of the 1934 Act, as follows:

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

            (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, referred to under (i) above; provided
     that (subject to Section 6(e) below) any such settlement is effected with
     the written consent of CEI; and

            (iii)  against any and all expense whatsoever, as incurred
     (including the fees and disbursements of counsel chosen by the Underwriter
     or the Company, as the case may be), reasonably incurred in investigating,
     preparing or defending against any litigation, or any investigation or
     proceeding by any governmental agency or body, commenced or threatened, or
     any claim whatsoever based upon any such untrue statement or omission,

                                       25
<PAGE>
 
     or any such alleged untrue statement or omission, referred to under (i)
     above, to the extent that any such expense is not paid under (i) or (ii)
     above;

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

     (c) Indemnification of the Company, Directors and Officers.  The
Underwriter agrees to indemnify and hold harmless the Company, its directors,
each of its officers who signed the ML&Co. Registration Statement, and each
person, if any, who controls the Company within the meaning of Section 15 of the
1933 Act or Section 20 of the 1934 Act against any and all loss, liability,
claim, damage and expense described in the indemnity contained in subsection (a)
of this Section, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the ML&Co.
Registration Statement (or any amendment thereto), including the Rule 430A
Information and the Rule 434 Information, if applicable, or any ML&Co.
preliminary prospectus or the ML&Co. Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished
to the Company by the Underwriter expressly for use in the ML&Co. Registration
Statement (or any amendment thereto) or such ML&Co. preliminary prospectus or
the ML&Co. Prospectus (or any amendment or supplement thereto).

     (d) Actions against Parties; Notification.  Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement.  An indemnifying party may participate at its own expense in the
defense of any such action.  If it so elects within a reasonable time after
receipt of such notice, an indemnifying party, jointly with any other
indemnifying parties receiving such notice, may assume the defense of such
action with counsel chosen by it and approved by the indemnified parties
defendant in such action, unless such indemnified parties reasonably object to
such assumption on the ground that there may be legal defenses available to them
which are different from or in addition to those available to such indemnifying
party.  If an indemnifying party assumes the defense of such action, the
indemnifying parties shall not be liable for any fees and expenses of counsel
for the indemnified parties incurred thereafter in connection with such action.
In no event shall the indemnifying parties be liable for fees and expenses of
more than one counsel (in addition to any local counsel) separate from their own
counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general

                                       26
<PAGE>
 
allegations or circumstances.  No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 6 or Section 7 hereof (whether or not the
indemnified parties are actual or potential parties thereto), unless such
settlement, compromise or consent (i) includes an unconditional release of each
indemnified party from all liability arising out of such litigation,
investigation, proceeding 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.

     (e) Settlement without Consent if Failure to Reimburse.  If at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(ii) and 6(b)(ii) effected without its written consent if (i) such
settlement is entered into more than 60 days after receipt by such indemnifying
party of the aforesaid request, (ii) such indemnifying party shall have received
notice of the terms of such settlement at least 30 days prior to such settlement
being entered into and (iii) such indemnifying party shall not have reimbursed
such indemnified party in accordance with such request prior to the date of such
settlement.

     (f) Conditions of Indemnification by CEI.  The obligations and liabilities
of CEI under Section 6(b) hereof with respect to untrue statements or omissions
or alleged untrue statements or omissions made in the Cox Registration Statement
(or any amendment thereto), or any Cox preliminary prospectus or the Cox
Prospectus (or any amendment or supplement thereto), other than in reliance upon
and in conformity with written information furnished to Cox by CEI expressly for
use in the Cox Registration Statement (or any amendment thereto) or such Cox
preliminary prospectus or the Cox Prospectus (or any amendment or supplement
thereto), shall be subject to the following terms and conditions:

             (i) the indemnified party shall have previously requested
     indemnification for the loss, liability, claim, damage or expense arising
     out of such untrue statements or omissions or alleged untrue statements or
     omissions from Cox under Section 4(a) of the Registration Agreement;

             (ii) CEI shall have received notice of the indemnified party's
     request for indemnification from Cox; and

             (iii)  Cox shall have failed to pay or reimburse such indemnified
     party, within 60 days from the date such request was made, in accordance
     with such request.

     SECTION 7.  Contribution.
                 ------------ 

     (a) If the indemnification provided for in Sections 6(a) and 6(c) is for
any reason unavailable to or insufficient to hold harmless an indemnified party
in respect of any losses, liabilities, claims, damages or expenses referred to
therein, then the Company and the Underwriter

                                       27
<PAGE>
 
shall contribute to the aggregate amount of such losses, liabilities, claims,
damages and expenses incurred by such indemnified party, as incurred, (i) in
such proportion as is appropriate to reflect the relative benefits received by
the Company on the one hand and the Underwriter on the other hand from the
offering of the Securities pursuant to this Agreement or (ii) if the allocation
provided by clause (i) is not permitted by applicable law, in such proportion as
is appropriate to reflect not only the relative benefits referred to in clause
(i) above but also the relative fault of the Company on the one hand and of the
Underwriter on the other hand in connection with the statements or omissions
which resulted in such losses, liabilities, claims, damages or expenses, as well
as any other relevant equitable considerations.

     The relative benefits received by the Company on the one hand and the
Underwriter on the other hand in connection with the offering of the Securities
pursuant to this Agreement shall be deemed to be in the same respective
proportions as the total net proceeds from the offering of the Securities
pursuant to this Agreement (before deducting expenses) received by the Company
and the total underwriting discount received by the Underwriter, in each case as
set forth on the cover of the ML&Co. Prospectus, or, if Rule 434 is used, the
corresponding location on the ML&Co. Term Sheet, bear to the aggregate initial
public offering price of the Securities as set forth on such cover.

     The relative fault of the Company on the one hand and the Underwriter on
the other hand shall be determined by reference to, among other things, whether
any such untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by the
Company or by the Underwriter and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

     Notwithstanding the provisions of this Section 7(a), the Underwriter shall
not be required to contribute any amount in excess of the amount by which the
total price at which the Securities underwritten by it and distributed to the
public were offered to the public exceeds the amount of any damages which the
Underwriter has otherwise been required to pay by reason of any such untrue or
alleged untrue statement or omission or alleged omission.

     The Company and the Underwriter agree that it would not be just and
equitable if contribution pursuant to this Section 7(a) were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 7(a).  The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 7(a) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

                                       28
<PAGE>
 
     For purposes of this Section 7(a), each person, if any, who controls the
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as the Underwriter, and
each director of the Company, each officer of the Company who signed the ML&Co.
Registration Statement, and each person, if any, who controls the Company within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall
have the same rights to contribution as the Company.

     (b) If the indemnification provided for in Section 6(b) hereof is for any
reason unavailable to or insufficient to hold harmless an indemnified party in
respect of any losses, liabilities, claims, damages or expenses referred to
therein, then CEI on the one hand and the Underwriter and the Company on the
other hand shall contribute to the aggregate amount of such losses, liabilities,
claims, damages and expenses incurred by such indemnified party, as incurred,
(i) in such proportion as is appropriate to reflect the relative benefits
received by CEI on the one hand and by the Underwriter and the Company on the
other hand from the offering of the Securities pursuant to this Agreement or
(ii) if the allocation provided by clause (i) is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of CEI on
the one hand and of the Underwriter and the Company on the other hand in
connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.  The relative benefits received from the offering of
the Securities pursuant to this Agreement shall be deemed to be such that the
Underwriter and the Company shall be responsible for that portion of the
aggregate amount of such losses, liabilities, claims, damages and expenses
represented by the percentage that the total underwriting discount received by
the Underwriter, as set forth on the cover of the ML&Co. Prospectus, or, if Rule
434 is used, the corresponding location on the ML&Co. Term Sheet, bears to the
aggregate initial public offering price of the Securities as set forth on such
cover and CEI shall be responsible for the balance.  The relative fault of CEI
on the one hand and the Underwriter and the Company on the other hand shall be
determined by reference to, among other things, whether any such untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by CEI or Cox on the one
hand or by the Underwriter or the Company on the other hand and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

     Notwithstanding the provisions of this Section 7(b), the Underwriter and
the Company shall not be required to contribute any amount in excess of the
amount by which the total price at which the Securities underwritten by the
Underwriter and distributed to the public were offered to the public exceeds the
amount of any damages which the Underwriter and the Company have otherwise been
required to pay by reason of any such untrue or alleged untrue statement or
omission or alleged omission.

     CEI, the Underwriter and the Company agree that it would not be just and
equitable if contribution pursuant to this Section 7(b) were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 7(b).  The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 7(b) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in

                                       29
<PAGE>
 
investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 7(b), each person, if any, who controls the
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as the Underwriter, and
each person, if any, who controls the Company within the meaning of Section 15
of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to
contribution as the Company.

     SECTION 8.  Representations, Warranties and Agreements to Survive Delivery.
                 --------------------------------------------------------------
All representations, warranties and agreements contained in this Agreement or in
certificates of officers of the Company, Cox or CEI submitted pursuant hereto,
shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of the Underwriter or controlling person, or
by or on behalf of the Company or CEI, and shall survive delivery of the
Securities to the Underwriter.

     SECTION 9.  Termination of Agreement.
                 ------------------------ 

     (a) Termination; General.  The Underwriter may terminate this Agreement, by
notice to the Company and CEI, at any time at or prior to Closing Time (i) if
there has been, since the time of execution of this Agreement or since the
respective dates as of which information is given in the ML&Co. Prospectus, any
material adverse change in the condition, financial or otherwise, or in the
earnings, business affairs or business prospects of the Company and its
subsidiaries considered as one enterprise, whether or not arising in the
ordinary course of business, or (ii) if there has been, since the time of
execution of this Agreement, or since the respective dates as of which
information is given in the Cox Prospectus, any material adverse change in the
condition, financial or otherwise, or in the earnings, business affairs or
business prospects of Cox and its subsidiaries considered as one enterprise,
whether or not arising in the ordinary course of business, or (iii) if there has
occurred any material adverse change in the financial markets in the United
States, any outbreak of hostilities or escalation thereof or other calamity or
crisis or any change or development involving a prospective change in national
or international political, financial or economic conditions, in each case the
effect of which is such as to make it, in the judgment of the Underwriter,
impracticable to market the Securities or to enforce contracts for the sale of
the Securities, or (iv) if trading in any securities of the Company or in the
Cox Common Stock has been suspended or limited by the Commission or the New York
Stock Exchange, or if trading generally on the American Stock Exchange or the
New York Stock Exchange or in the Nasdaq National Market has been suspended or
limited, or minimum or maximum prices for trading have been fixed, or maximum
ranges for prices have been required, by any of said exchanges or by such system
or by order of the Commission, the NASD or any other governmental authority, or
(v) if a banking moratorium has been declared by either federal or New York
authorities.

                                       30

be binding upon each of the Underwriter, the Company and CEI and their

       (xvi)  No filing with, or authorization, approval, consent, license,

  proceeds from the sale of the Securities as described in the ML&Co. Prospectus
  under the caption "Supplemental Use of Proceeds") and compliance by the

                                      A-3
<PAGE>
 
  with or constitute a breach of, or default or Repayment Event (as defined in

  creation or imposition of any lien, charge or encumbrance upon any property or
  assets of the Company or any subsidiary pursuant to any contract, indenture,
  mortgage, deed of trust, loan or credit agreement, note, lease or any other
  agreement or instrument, known to us, to which the Company or any subsidiary
  is a party or by which it or any of them may be bound, or to which any of the
  property or assets of the Company or any subsidiary is subject (except for
  such conflicts, breaches or defaults or liens, charges or encumbrances that
  would not have a Material Adverse Effect), nor will such action result in any
  violation of the provisions of the charter or by-laws of the Company or any
  subsidiary, or any applicable law, statute, rule, regulation, judgment, order,
  writ or decree, known to us, of any government, government instrumentality or
  court, domestic or foreign, having jurisdiction over the Company or any
  subsidiary or any of their respective properties, assets or operations.

       We have participated in conferences with officers and representatives of
  the Company and Cox, representatives of the independent accountants of the
  Company and Cox, and the Underwriter at which the contents of the ML&Co.
  Registration Statement and Prospectus, the contents of the Cox Registration
  Statement and Prospectus and related matters were discussed and, although we
  are not passing upon or assuming responsibility for the accuracy, completeness
  or fairness of the statements contained or incorporated by reference in said
  Registration Statements and Prospectuses and have made no independent check or
  verification thereof, on the basis of the foregoing, nothing has come to our
  attention that would lead us to believe (i) that the ML&Co. Registration
  Statement or any amendment thereto, including the Rule 430A Information and
  Rule 434 Information (if applicable), (except for financial statements and
  schedules and other financial data included or incorporated by reference
  therein or omitted therefrom and the Form T-1, as to which we need make no
  statement), at the time such ML&Co. Registration Statement or any such
  amendment became effective or at the date of the Underwriting Agreement,
  contained an untrue statement of a material fact or omitted to state a
  material fact required to be stated therein or necessary to make the
  statements therein not misleading or that the ML&Co. Prospectus or any
  amendment or supplement thereto (except for financial statements and schedules
  and other financial data included or incorporated by reference therein or
  omitted therefrom, as to which we need make no statement), at the  time the
  ML&Co. Prospectus was issued, at the time any such amended or supplemented
  prospectus was issued or at the Closing Time, included or includes an untrue
  statement of a material fact or omitted or omits to state a material fact
  necessary in order to make the statements therein, in the light of the
  circumstances under which they were made, not misleading, or (ii) that the Cox
  Registration Statement or any amendment thereto, (except for financial
  statements and schedules and other financial data included or incorporated by
  reference therein or omitted therefrom, as to which we need make no
  statement), at the time such Cox Registration Statement or any such amendment
  became effective, contained an untrue statement of a material fact or omitted
  to state a material fact required to be stated therein or necessary to make
  the statements therein not misleading or that the Cox Prospectus or any
  amendment or supplement thereto (except for financial statements and schedules
  and other financial data included or incorporated by reference therein or
  omitted therefrom, as to which we need make no statement), at the time the Cox
  Prospectus was issued, at the time any such amended or supplemented prospectus
  was issued or at the Closing Time, included or includes an untrue statement of
  a material fact or omitted or omits to state a material fact necessary in
  order to make

                                      A-4
<PAGE>
 
  the statements therein, in the light of the circumstances under which they
  were made, not misleading.

  In rendering such opinion, such counsel may rely as to matters of fact (but
not as to legal conclusions), to the extent they deem proper, on certificates of
responsible officers of the Company and public officials.

  corporate power and authority to own, lease and operate its properties and to
  conduct its business as described in the Cox Prospectus and to enter into and
  perform its obligations under the Registration Agreement and is duly qualified
  as a foreign corporation to transact business and is in good standing in each
  jurisdiction in which such qualification is required, whether by reason of the
  ownership or leasing of property or the conduct of business, except where the
  failure so to qualify or to be in good standing would not result in a Material
  Adverse Effect.

       (ii) CEI has been duly incorporated and is validly existing as a

  incorporation and has corporate power and authority to enter into and perform
  its obligations under the Underwriting Agreement and the STRYPES Agreement.

       (iv) Cox Holdings is the sole registered owner of and has all rights as a
  registered owner in and to at least 14,000,000 shares of Cox Common Stock,

       (v) Each material subsidiary of Cox (set forth on Schedule A hereto)
  (each, a "Subsidiary" and collectively, the "Subsidiaries") has been duly
  incorporated, is validly existing as a corporation in good standing under the
  laws of the jurisdiction of its incorporation, has the corporate power and
  authority to own its property and to conduct its business as described in the
  Cox Prospectus and is duly qualified to transact business and is in good
  standing in each jurisdiction in which the conduct of its business or its

  as otherwise disclosed in the Cox Registration Statement, all of the capital
  stock of each Subsidiary owned by Cox, directly or through subsidiaries, has
  been duly authorized and validly

                                      B-1

  delivered by CEI and (assuming the due authorization, execution and delivery

  agreement of CEI, enforceable against CEI in accordance with its terms, except
  as the enforcement thereof may be limited by bankruptcy, insolvency
  (including, without limitation, all laws relating to fraudulent transfers),
  reorganization, moratorium or similar laws affecting enforcement of creditors'
  rights generally and except as enforcement thereof is subject to general
  principles of equity (regardless of whether enforcement is considered in a
  proceeding in equity or at law).

       (ix) The Cox Registration Statement, including any Cox Rule 462(b)
  Registration Statement, has been declared effective under the 1933 Act; any
  required filing of the Cox Prospectus pursuant to Rule 424(b) has been made in
  the manner and within the time period required by Rule 424(b); and, to the
  best of our knowledge, no stop order suspending the effectiveness of the Cox
  Registration Statement or any Cox Rule 462(b) Registration Statement has been
  issued under the 1933 Act and no proceedings for that purpose have been
  instituted or are pending or threatened by the Commission.

       (x) The Cox Registration Statement, including any Cox Rule 462(b)
  Registration Statement, the Cox Prospectus, excluding the documents
  incorporated by reference therein, and each amendment or supplement to the Cox
  Registration Statement and Cox Prospectus, excluding the documents
  incorporated by reference therein, as of their respective effective or issue
  dates (other than the financial statements and supporting schedules or other
  financial or statistical data included therein or omitted therefrom, as to
  which we need express no opinion) complied as to form in all material respects
  with the requirements of the 1933 Act and the 1933 Act Regulations.

       (xi) The documents incorporated by reference in the Cox Prospectus (other
  than the financial statements and supporting schedules or other financial or
  statistical data included therein or omitted therefrom, as to which we need
  express no opinion), when they became effective or were filed with the
  Commission, as the case may be, complied as to form in all material respects
  with the requirements of the 1933 Act or the 1934 Act, as applicable, and the
  rules and regulations of the Commission thereunder.

       (xii)  The form of certificate used to evidence the Cox Common Stock
  complies in all material respects with all applicable statutory requirements,
  with any applicable requirements of the charter and by-laws of Cox.

                                      B-2
<PAGE>
 
       (xiii)  To our knowledge and other than as set forth in the Cox
  Prospectus, there is not pending any action, suit, proceeding, inquiry or
  investigation, to which Cox or any subsidiary is a party, or to which the
  property of Cox or any subsidiary is subject, before or brought by any court
  or governmental agency or body, domestic or foreign, (including the U.S.
  Federal Communications Commission ("FCC")) which might reasonably be expected
  to result in a Material Adverse Effect, or which might reasonably be expected
  to materially and adversely affect the properties or assets thereof or the
  consummation of the transactions contemplated in the Registration Agreement or
  the performance by Cox of its obligations thereunder; and, to the best of our
  knowledge, no such action, suit, proceeding, inquiry or investigation is
  threatened in writing by governmental authorities or others.

       (xiv)  The information in the Prospectus under "Business--Legislation and
  Regulation", "Certain Transactions" and "Description of Capital Stock", and in
  the Registration Statement under Items 14 and 15, to the extent that it
  constitutes matters of law, summaries of legal matters, Cox's charter and
  bylaws or legal proceedings, or legal conclusions, has been reviewed by us and
  fairly present the information called for with respect to such matters of law
  and fairly summarize the matters referred to therein.

       (xv) To the best of our knowledge, there are no statutes or regulations,
  and no legal or governmental proceedings pending or threatened to which Cox or
  any of its subsidiaries is a party or to which any of the properties of Cox or
  any of its subsidiaries is subject, that are required to be described in the
  Cox Prospectus that are not described as required.

       (xvi)  All descriptions in the Cox Registration Statement of contracts
  and other documents to which Cox or its subsidiaries are a party are accurate
  in all material respects; to the best of our knowledge, there are no
  franchises, contracts, indentures, mortgages, loan agreements, notes, leases
  or other instruments required to be described or referred to in the Cox
  Registration Statement or to be filed as exhibits thereto other than those
  described or referred to therein or filed or incorporated by reference as
  exhibits thereto, and the descriptions thereof or references thereto are
  correct in all material respects.

       (xvii)  No filing with, or authorization, approval, consent, license,
  order, registration, qualification or decree of, any court or governmental
  authority or agency, domestic or foreign, (including the FCC) (other than
  under the 1933 Act and the 1933 Act Regulations, which have been obtained, or
  as may be required under the securities or blue sky laws of the various
  states, as to which we need express no opinion) is necessary or required in
  connection with the due authorization, execution, and delivery by Cox of the
  Registration Agreement or the performance by Cox of its obligations
  thereunder.

       (xviii) The execution, delivery and performance of the Registration
  Agreement and the consummation of the transactions contemplated in the
  Registration Agreement and in the Cox Registration Statement and compliance by
  Cox with its obligations under the Registration Agreement do not and will not,
  whether with or without the giving of notice or lapse of time or both,
  conflict with or constitute a breach of, or default or Repayment Event (as
  defined in Section 1(a)(xi) of the Registration Agreement) under or result in
  the creation or imposition of any lien, charge or encumbrance upon any
  property or assets of Cox or any subsidiary pursuant to, any

                                      B-3
<PAGE>
 
  contract, indenture, mortgage, deed of trust, loan or credit agreement, note,
  lease or any other agreement or instrument, known to us, to which Cox or any
  subsidiary is a party or by which it or any of them may be bound, or to which
  any of the property or assets of Cox or any subsidiary is subject (except for
  such conflicts, breaches or defaults or liens, charges or encumbrances that
  would not have a Material Adverse Effect), nor will such action result in any
  violation of the provisions of the charter or by-laws of Cox or any
  subsidiary, or, to our knowledge, any applicable law, statute, rule,
  regulation, judgment, order, writ or decree of any government, government
  instrumentality or court, domestic or foreign, having jurisdiction over Cox or
  any subsidiary or any of their respective properties, assets or operations.

       (xix)  No filing with, or authorization, approval, consent, license,
  order, registration, qualification or decree of, any court or governmental
  authority or agency (including the FCC) (other than under the 1933 Act and the
  1933 Act Regulations, which have been obtained, or as may be required under
  the securities or blue sky laws of the various states, as to which we need
  express no opinion) is necessary or required in connection with the due
  authorization, execution and delivery by CEI of the Underwriting Agreement or
  the STRYPES Agreement or the performance by CEI of its obligations thereunder.

       (xx) The execution, delivery and performance by CEI of the Underwriting
  Agreement and the STRYPES Agreement and the consummation by CEI of the
  transactions contemplated therein and compliance by CEI with its obligations
  thereunder do not and will not, whether with or without the giving of notice
  or lapse of time or both, conflict with or constitute a breach of, or default
  or CEI Repayment Event under or result in the creation or imposition of any
  lien, charge or encumbrance upon any property or assets of CEI or any of its
  subsidiaries pursuant to, any contract, indenture, mortgage, deed of trust,
  loan or credit agreement, note, lease or any other agreement or instrument,
  known to us, to which CEI or any of its subsidiaries is a party or by which it
  or any of them may be bound, or to which any of the property or assets of CEI
  or any of its subsidiaries is subject (except for such conflicts, breaches or
  defaults or liens, charges or encumbrances that would not, singly or in the
  aggregate, materially and adversely affect the ability of CEI to perform its
  obligations under the Underwriting Agreement or the STRYPES Agreement), nor
  will such action result in any violation of the provisions of the charter or
  by-laws of CEI or any of its subsidiaries, or, to our knowledge, any
  applicable law, statute, rule, regulation, judgment, order, writ or decree of
  any government, government instrumentality or court, domestic or foreign,
  having jurisdiction over CEI or any of its subsidiaries or any of their
  respective assets, properties or operations (except for such violations that
  would not, singly or in the aggregate, materially and adversely affect the
  ability of CEI to perform its obligations under the Underwriting Agreement or
  the STRYPES Agreement).

       (xxi) Cox has been granted and presently holds the FCC authorizations
  necessary for Cox to conduct its business as presently conducted or proposed
  to be conducted, except such as would not have, singly or in the aggregate
  with all such other authorizations that have not been granted or are not
  presently held, a Material Adverse Effect; such FCC authorizations are in full
  force and effect, except when the invalidity of such authorizations or the
  failure of such authorizations to be in full force and effect would not have a
  Material Adverse Effect; and to our knowledge, no proceedings to revoke or
  modify any of such FCC authorizations are pending or threatened.

                                      B-4
<PAGE>
 
       (xxii)To our knowledge after due inquiry, we are of the opinion that Cox
  is not, nor with the giving of notice or lapse of time or both would be, in
  violation of any judgment, injunction, order or decree of the FCC other than
  those that would not have, singly or in the aggregate with all such other
  violations, a Material Adverse Effect.

       (xxiii)The execution, delivery and performance of the Registration
  Agreement by Cox, and the execution, delivery and performance of the
  Underwriting Agreement and the STRYPES Agreement by CEI, do not violate the
  Communications Act of 1934, as amended, or any rules or the regulations
  thereunder binding on Cox, CEI or their respective subsidiaries or any order,
  writ, judgment, injunction, decree or award of the FCC binding on Cox, CEI or
  their respective subsidiaries of which we have knowledge after due inquiry.

       (xxiv)The execution, delivery and performance of the STRYPES Agreement
  does not constitute the transfer or assignment, directly or indirectly, of any
  license existing as of the date hereof issued by the FCC in connection with
  the operations of Cox or the transfer of control of Cox within the meaning of
  Section 310(d) of the Communications Act of 1934, as amended.

       (xxv)  Cox is not an "investment company" or an entity "controlled" by an
  "investment company," as such terms are defined in the 1940 Act.

       We have participated in conferences with officers and representatives of
  Cox, representatives of the independent accountants of Cox, and the
  Underwriter at which the contents of the Cox Registration Statement and the
  Cox Prospectus and related matters were discussed and, although we are not
  passing upon or assuming responsibility for the accuracy, completeness or
  fairness of the statements contained or incorporated by reference in the Cox
  Registration Statement and the Cox Prospectus and have made no independent
  check or verification thereof except as described in paragraph (xv) above, on
  the basis of the foregoing, nothing has come to our attention that would lead
  us to believe that the Cox Registration Statement or any amendment thereto
  (except for financial statements and schedules and other financial data
  included or incorporated by reference therein or omitted therefrom, as to
  which we need make no statement), at the time such Cox Registration Statement
  or any such amendment became effective, contained an untrue statement of a
  material fact or omitted to state a material fact required to be stated
  therein or necessary to make the statements therein not misleading or that the
  Cox Prospectus or any amendment or supplement thereto (except for financial
  statements and schedules and other financial data included or incorporated by
  reference therein or omitted therefrom, as to which we need make no
  statement), at the time the Cox Prospectus was issued, at the time any such
  amended or supplemented prospectus was issued or at the Closing Time, included
  or includes an untrue statement of a material fact or omitted or omits to
  state a material fact necessary in order to make the statements therein, in
  the light of the circumstances under which they were made, not misleading.

       In rendering such opinion, such counsel may rely (A) as to matters
  involving the application of laws other than the laws of the State of New
  York, the corporate laws of the State of Delaware or the federal laws of the
  United States of America, to the extent such counsel deems proper and
  specified in such opinion, upon the opinion of other counsel whom such counsel
  believes to be reliable, provided that such counsel furnishes copies thereof
  to the Underwriter and

                                      B-5
<PAGE>
 
  states that  such opinion of such local counsel is satisfactory in form and
  substance and the Underwriter and counsel for the Underwriter are entitled to
  rely thereon, and (B) as to matters of fact (but not as to legal conclusions),
  to the extent they deem proper, on certificates of responsible officers of
  Cox, CEI and public officials.  As used in this Exhibit B, the term "Material
  Adverse Effect" shall have the meaning ascribed to such term in the
  Registration Agreement.

Ladies and Gentlemen:

     Cox Communications, Inc., a Delaware corporation (the "Company"), and Cox
Enterprises, Inc., a Delaware corporation ("CEI"), confirm their respective
agreements with Merrill Lynch & Co., Inc., a Delaware corporation ("ML&Co."),
and with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated
(the "Underwriter"), in connection with the proposed issue and sale by ML&Co. to
the Underwriter, pursuant to an underwriting agreement, dated the date hereof
(the "Underwriting Agreement"), among ML&Co., CEI and the Underwriter, of an
aggregate of 8,500,000 of ML&Co.'s Structured Yield Product Exchangeable for
Stock/SM/, 6% STRYPES/SM/ due June 1, 1999 (each, a "STRYPES"), payable at
maturity or upon redemption by delivery of shares of Class A Common Stock, par
value $1.00 per share (the "Cox Common Stock"), of the Company, and, at the
option of the Underwriter, all or any part of 1,275,000 additional STRYPES to
cover over-allotments, if any.  The aforesaid 8,500,000 STRYPES (the "Initial
Securities") to be purchased by the Underwriter and all or any part of the
1,275,000 STRYPES subject to the option described in Section 2(b) of the
Underwriting Agreement (the "Option Securities") are hereinafter called,
collectively, the "Securities."  Capitalized terms used herein and not otherwise
defined shall have the meanings ascribed to them in the Underwriting Agreement.

                                       1
<PAGE>
 
     The Company understands that the Underwriter proposes to make a public
offering of the Securities as soon as the Underwriter deems advisable after this
Agreement and the Underwriting Agreement have been executed and delivered.  The
Company acknowledges that the execution and delivery of this Agreement is a
condition to the execution and delivery of the Underwriting Agreement by the
Underwriter and ML&Co. and that, in consideration of the execution and delivery
of the Underwriting Agreement by the Underwriter and ML&Co., the Company is
willing to make the representations, warranties and covenants herein contained.

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-03351) covering the
registration of (i) the shares of Cox Common Stock deliverable at maturity or
upon redemption of the Securities and (ii) 4,225,000 shares of Cox Common Stock
(the "Pledged Shares") that may be pledged to and sold by or on behalf of the
ML&Co. Subsidiary (as defined below) under the Securities Act of 1933, as
amended (the "1933 Act"), including the related preliminary prospectus or
prospectuses.  Each prospectus used before such registration statement became
effective is herein called a "Cox preliminary prospectus."  Such registration
statement, including the exhibits thereto, the schedules thereto, if any, and
the documents incorporated by reference therein pursuant to Item 12 of Form S-3
under the 1933 Act, at the time it became effective, is herein called the "Cox
Registration Statement."  Any registration statement filed pursuant to Rule
462(b) of the rules and regulations of the Commission under the 1933 Act (the
"1933 Act Regulations") is herein referred to as the "Cox Rule 462(b)
Registration Statement," and after such filing the term "Cox Registration
Statement" shall include the Cox Rule 462(b) Registration Statement.  The final
prospectus, including the documents incorporated by reference therein pursuant
to Item 12 of Form S-3 under the 1933 Act, in the form first furnished to the
Underwriter for use in connection with the offering of the Securities is herein
called the "Cox Securities Prospectus."  The prospectus, including the documents
incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933
Act, in the form furnished from time to time to the ML&Co. Subsidiary for use in
connection with the sale of the Pledged Shares is herein called the "Pledged
Share Prospectus" and, together with the Cox Securities Prospectus, the "Cox
Prospectus."  For purposes of this Agreement, all references to the Cox
Registration Statement, any Cox preliminary prospectus, the Cox Prospectus or
any amendment or supplement to any of the foregoing shall be deemed to include
the copy filed with the Commission pursuant to its Electronic Data Gathering,
Analysis and Retrieval system ("EDGAR").

     All references in this Agreement to financial statements and schedules and
other information which is "contained," "included" or "stated" in the Cox
Registration Statement, any Cox preliminary prospectus or the Cox Prospectus (or
other references of like import) shall be deemed to mean and include all such
financial statements and schedules and other information which is incorporated
by reference in the Cox Registration Statement, any Cox preliminary prospectus
or the Cox Prospectus, as the case may be; and all references in this Agreement
to amendments or supplements to the Cox Registration Statement, any Cox
preliminary prospectus or the Cox Prospectus shall be deemed to mean and include
the filing of any document under the Securities Exchange Act of 1934, as amended
(the "1934 Act"), which is incorporated by reference in the Cox Registration
Statement, such Cox preliminary prospectus or the Cox Prospectus, as the case
may be.

                                       2
<PAGE>
 
     Prior to the closing under the Underwriting Agreement, ML&Co., Merrill
Lynch Capital Services, Inc., a wholly-owned subsidiary of ML&Co. (the "ML&Co.
Subsidiary"), and CEI will enter into a contract (the "STRYPES Agreement"),
pursuant to which CEI will be obligated to deliver to the ML&Co. Subsidiary,
immediately prior to the maturity date or date of redemption of the Securities,
a number of shares of Cox Common Stock equal to the number required by ML&Co. to
pay and discharge or redeem all of the Securities, subject to CEI's option,
exercisable in its sole discretion, to satisfy its obligation under the STRYPES
Agreement by delivering immediately prior to the maturity date a specified
amount of cash in lieu of such shares.


     SECTION 1.  Representations and Warranties.
                 ------------------------------ 

     (a) Representations and Warranties by the Company.  The Company represents
and warrants to each of the Underwriter and to ML&Co. as of the date hereof, as
of the Closing Time referred to in Section 2(c) of the Underwriting Agreement,
and as of each Date of Delivery (if any) referred to in Section 2(b) of the
Underwriting Agreement, and agrees with each of the Underwriter and ML&Co. as
follows:

            (i)  Compliance with Registration Requirements.  The Company meets
                 -----------------------------------------                    
     the requirements for the use of Form S-3 under the 1933 Act.  Each of the
     Cox Registration Statement and any Cox Rule 462(b) Registration Statement
     has become effective under the 1933 Act and no stop order suspending the
     effectiveness of the Cox Registration Statement or any Cox Rule 462(b)
     Registration Statement has been issued under the 1933 Act and no
     proceedings for that purpose have been instituted or are pending or, to the
     knowledge of the Company, are contemplated by the Commission, and any
     request on the part of the Commission for additional information has been
     complied with.

            At the respective times the Cox Registration Statement, any Cox Rule
     462(b) Registration Statement and any post-effective amendments thereto
     became effective and at the Closing Time (and at the Date of Delivery if
     any Option Securities are purchased and at the date of delivery of the
     Pledged Share Prospectus to the ML&Co. Subsidiary if any Pledged Shares are
     sold), the Cox Registration Statement, the Cox Rule 462(b) Registration
     Statement and any amendments and supplements thereto complied and will
     comply in all material respects with the requirements of the 1933 Act and
     the 1933 Act Regulations and did not and will not contain an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading.  Neither the Cox Prospectus nor any amendments or supplements
     thereto, at the time the Cox Prospectus or any such amendment or supplement
     was issued and at the Closing Time (and at the Date of Delivery if any
     Option Securities are purchased and at the date of delivery of the Pledged
     Share Prospectus to the ML&Co. Subsidiary if any Pledged Shares are sold),
     included or will include an untrue statement of a material fact or omitted
     or will omit to state a material fact necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading.  The representations and warranties in this
     subsection shall not apply to statements in or omissions from the Cox
     Registration Statement or Cox Prospectus made in reliance upon and in
     conformity with (x) information furnished to the Company in writing by the
     Underwriter expressly for use in the Cox Registration

                                       3
<PAGE>
 
     Statement or Cox Prospectus and (y) information furnished to the Company in
     writing by ML&Co. expressly for use in the Cox Registration Statement or
     Cox Prospectus.

            Each Cox preliminary prospectus and the Cox Prospectus filed as part
     of the Cox Registration Statement as originally filed or as part of any
     amendment thereto, or filed pursuant to Rule 424 under the 1933 Act,
     complied when so filed in all material respects with the 1933 Act
     Regulations and, if applicable, each Cox preliminary prospectus and the Cox
     Prospectus delivered to the Underwriter for use in connection with the
     offering of the Securities was identical to the electronically transmitted
     copies thereof filed with the Commission pursuant to EDGAR, except to the
     extent permitted by Regulation S-T.

            (ii)  Incorporated Documents.  The documents incorporated or deemed
                  ----------------------                                       
     to be incorporated by reference in the Cox Registration Statement and the
     Cox Prospectus, when they became effective or at the time they were or
     hereafter are filed with the Commission, complied and will comply in all
     material respects with the requirements of the 1933 Act and the 1933 Act
     Regulations or the 1934 Act and the rules and regulations of the Commission
     thereunder (the "1934 Act Regulations"), as applicable, and, when read
     together with the other information in the Cox Prospectus, at the time the
     Cox Registration Statement became effective, at the time the Cox Prospectus
     was issued and at the Closing Time (and at the Date of Delivery if any
     Option Securities are purchased and at the date of delivery of the Pledged
     Share Prospectus to the ML&Co. Subsidiary if any Pledged Shares are sold),
     did not and will not contain an untrue statement of a material fact or omit
     to state a material fact required to be stated therein or necessary to make
     the statements therein not misleading.

            (iii)  Independent Accountants.  The accountants who certified the
                   -----------------------

     subsidiaries, and of Times Mirror Cable Television, Inc. and its
     subsidiaries ("Times Mirror"), included in the Cox Registration Statement
     are independent public accountants as required by the 1933 Act and the 1933
     Act Regulations.

            (iv)  Financial Statements.  The financial statements of the Company
                  --------------------

     with the related schedules and notes, present fairly the financial position
     of the Company and its consolidated subsidiaries at the dates indicated and

     Company and its consolidated subsidiaries for the periods specified; said
     financial statements have been prepared in conformity with generally
     accepted accounting principles ("GAAP") applied on a consistent basis
     throughout the periods involved.  The financial statements of Times Mirror
     included in the Cox Registration Statement and the Cox Prospectus, together
     with the related notes, present fairly the financial position of Times
     Mirror and its consolidated subsidiaries at the dates indicated and the
     statement of operations, stockholders' equity and cash flows of Times
     Mirror and its consolidated subsidiaries for the periods specified; said
     financial statements have been prepared in conformity with GAAP applied on
     a consistent basis throughout the periods involved.  The supporting
     schedules, if any, included in the Cox

     Registration Statement present fairly in accordance with GAAP the
     information required to be stated therein.  The selected financial data and
     the summary financial information included in the Cox Prospectus present
     fairly the information shown therein and have been compiled on a basis
     consistent with that of the audited financial statements of the Company and
     its subsidiaries included in the Cox Registration Statement.  The selected

     information shown therein and have been compiled from pro forma financial
     statements prepared in accordance with the Commission's rules and
     guidelines with respect to pro forma financial statements.

            (v)  No Material Adverse Change in Business.  Since the respective

The Company will promptly effect the filings necessary pursuant to Rule 424(b)
and will take such steps as it deems necessary to ascertain promptly whether the
form of prospectus transmitted for filing under Rule 424(b) was received for
filing by the Commission and, in the event that it was not, it will promptly

reasonably object.

     (c) Delivery of Cox Registration Statements.  The Company has furnished or
will deliver to the Underwriter, counsel for the Underwriter, ML&Co. and counsel
for ML&Co., without charge, signed copies of the Cox Registration Statement as
originally filed and of each amendment thereto (including exhibits filed
therewith or incorporated by reference therein and documents incorporated or
deemed to be incorporated by reference therein) and signed copies of all
consents and certificates of experts.  If applicable, the copies of the Cox

Regulation S-T.

     (d) Delivery of Cox Prospectuses.  The Company has delivered to the
Underwriter, without charge, as many copies of each Cox preliminary prospectus

Securities or the Pledged Shares, any event shall occur or condition shall exist
as a result of which it is necessary, in the reasonable opinion of counsel for
the Underwriter, counsel for ML&Co. or counsel for the Company, to amend the Cox
Registration Statement or amend or supplement the Cox Prospectus in order that
the Cox Prospectus will not include any untrue statements of a material fact or
omit to state a material fact necessary in order to make the statements therein
not misleading in the light of the circumstances existing at the time it is
delivered to a purchaser, or if it shall be necessary, in the reasonable opinion
of any such counsel, at any such time to amend the Cox Registration Statement or
amend or supplement the Cox Prospectus in order to comply with the requirements
of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare
and file with the Commission, subject to Section 2(b), such amendment or

controls the Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act and (2) ML&Co. and each person, if any, who controls
ML&Co. within the meaning of Section 15 of the 1933 Act or Section 20 of the
1934 Act, as follows:

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

            (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, referred to under (i) above; provided
     that (subject to Section 4(d) below) any such settlement is effected with
     the written consent of the Company; and

            (iii)  against any and all expense whatsoever, as incurred
     (including the fees and disbursements of counsel chosen by the Underwriter
     or ML&Co., as the case may be), reasonably incurred in investigating,
     preparing or defending against any litigation, or any investigation or
     proceeding by any governmental agency or body, commenced or

                                       12
<PAGE>
 
     threatened, or any claim whatsoever based upon any such untrue statement or
     omission, or any such alleged untrue statement or omission, referred to
     under (i) above, to the extent that any such expense is not paid under (i)
     or (ii) above;

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

     (b) Indemnification of Company, Directors, Officers.  The Underwriter
agrees to indemnify and hold harmless the Company, its directors, each of its
officers who signed the Cox Registration Statement, and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act against any and all loss, liability, claim, damage and
expense described in the indemnity contained in subsection (a) of this Section,
as incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Cox Registration Statement (or any
amendment thereto),  or any Cox preliminary prospectus or the Cox Prospectus (or
any amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Company by the Underwriter expressly for
use in the Cox Registration Statement (or any amendment thereto) or such Cox
preliminary prospectus or the Cox Prospectus (or any amendment or supplement
thereto).

     (c) Actions against Parties; Notification.  Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement.  An indemnifying party may participate at its own expense in the
defense of any such action.  If it so elects within a reasonable time after
receipt of such notice, an indemnifying party, jointly with any other
indemnifying parties receiving such notice, may assume the defense of such
action with counsel chosen by it and approved by the indemnified parties
defendant in such action, unless such indemnified parties reasonably object to
such assumption on the ground that there may be legal defenses available to them
which are different from or in addition to those available to such indemnifying
party.  If an indemnifying party assumes the defense of such action, the
indemnifying parties shall not be liable for any fees and expenses of counsel
for the indemnified parties incurred thereafter in connection with such action.
In no event shall the indemnifying parties be liable for fees and expenses of
more than one counsel (in addition to any local counsel) separate from their own
counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general

                                       13
<PAGE>
 
allegations or circumstances.  No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 4 or Section 5 hereof (whether or not the
indemnified parties are actual or potential parties thereto), unless such
settlement, compromise or consent (i) includes an unconditional release of each
indemnified party from all liability arising out of such litigation,
investigation, proceeding 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.

     (d) Settlement without Consent if Failure to Reimburse.  If at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 4(a)(ii) effected without its written consent if (i) such settlement is
entered into more than 60 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.

     SECTION 5.  Contribution.  If the indemnification provided for in Section 4
                 ------------                                                   
hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then the Company on the one hand and the
Underwriter and ML&Co. on the other hand shall contribute to the aggregate
amount of such losses, liabilities, claims, damages and expenses incurred by
such indemnified party, as incurred, (i) in such proportion as is appropriate to
reflect the relative benefits received by the Company on the one hand and the
Underwriter and ML&Co. on the other hand from the offering of the Securities
pursuant to the Underwriting Agreement or (ii) if the allocation provided by
clause (i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company on the one hand and of the
Underwriter and ML&Co. on the other hand in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

     The relative benefits received by the offering of the Securities pursuant
to the Underwriting Agreement shall be deemed to be such that the Underwriter
and ML&Co. shall be responsible for that portion of the aggregate amount of such
losses, liabilities, claims, damages and expenses represented by the percentage
that the total underwriting discount received by the Underwriter, as set forth
on the cover of the ML&Co. Prospectus, or, if Rule 434 is used, the
corresponding location on the ML&Co. Term Sheet, bears to the aggregate initial
public offering price of the Securities as set forth on such cover and the
Company shall be responsible for the balance.

     The relative fault of the Company on the one hand and the Underwriter and
ML&Co. on the other hand shall be determined by reference to, among other
things, whether any such untrue

                                       14
<PAGE>
 
or alleged untrue statement of a material fact or omission or alleged omission
to state a material fact relates to information supplied by the Company or CEI
on the one hand or by the Underwriter or ML&Co. on the other hand and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

     Notwithstanding the provisions of this Section 5, the Underwriter and
ML&Co. shall not be required to contribute any amount in excess of the amount by
which the total price at which the Securities underwritten by the Underwriter
and distributed to the public were offered to the public exceeds the amount of
any damages which the Underwriter and ML&Co. have otherwise been required to pay
by reason of any such untrue or alleged untrue statement or omission or alleged
omission.

     The Company, the Underwriter and ML&Co. agree that it would not be just and
equitable if contribution pursuant to this Section 5 were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this Section 5.  The aggregate
amount of losses, liabilities, claims, damages and expenses incurred by an
indemnified party and referred to above in this Section 5 shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 5, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as the Underwriter; each
person, if any, who controls ML&Co. within the meaning of Section 15 of the 1933
Act shall have the same rights to contribution as ML&Co.; and each director of
the Company, each officer of the Company who signed the Cox Registration
Statement, and each person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same
rights to contribution as the Company.

     SECTION 6.  Representations, Warranties and Agreements to Survive Delivery.
                 -------------------------------------------------------------- 
All representations, warranties and agreements contained in this Agreement or in
certificates of officers of the Company submitted pursuant to the Underwriting
Agreement, shall remain operative and in full force and effect, regardless of
any investigation made by or on behalf of the Underwriter or controlling person
thereof, or by or on behalf of ML&Co. or controlling person thereof or by or on
behalf of the Company, and shall survive delivery of the Securities to the
Underwriter pursuant to the Underwriting Agreement and any sale of the Pledged
Shares.

     SECTION 7.  Termination.  In the event that the Underwriter terminates the
                 -----------                                                   
Underwriting Agreement as provided in Section 9 thereof, this Agreement shall
simultaneously terminate, except that the provisions of Section 3, the indemnity
agreements set forth in Section

                                       15
<PAGE>
 
4, the contribution provisions set forth in Section 5, and the provisions of
Section 6 shall remain in effect.

     SECTION 8.  Notices.  All notices and other communications hereunder shall
                 -------                                                       
be in writing and shall be deemed to have been duly given if mailed or

notices to ML&Co. shall be directed to it at 100 Church St., 12th Floor, New

at World Financial Center, South Tower, New York, New York 10080-6105; notices
to the Company or CEI shall be directed to it at 1400 Lake Hearn Drive, Atlanta,
Georgia 30319, attention of Andrew A. Merdek.

     SECTION 9.  Parties.  This Agreement shall inure to the benefit of and be
                 -------                                                      
binding upon each of the Underwriter, ML&Co., the Company and CEI and their
respective successors.  Nothing expressed or mentioned in this Agreement is
intended or shall be construed to give any person, firm or corporation, other
than the Underwriter, ML&Co., the Company and CEI and their respective
successors and the controlling persons and officers and directors referred to in
Sections 4 and 5 and their heirs and legal representatives, any legal or
equitable right, remedy or claim under or in respect of this Agreement or any
provision herein contained.  This Agreement and all conditions and provisions
hereof are intended to be for the sole and exclusive benefit of the Underwriter,
ML&Co., the Company and CEI and their respective successors, and said
controlling persons and officers and directors and their heirs and legal
representatives, and for the benefit of no other person, firm or corporation.
No purchaser of Securities from the Underwriter shall be deemed to be a
successor by reason merely of such purchase.

     SECTION 10. GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND
                 -------------                                          
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     SECTION 11. Effect of Headings.  The Article and Section headings herein

                                  THE STRYPES

     SECTION 201.  Description of the STRYPES.  The Securities shall be known
                   --------------------------                                
and designated as the "Structured Yield Product Exchangeable for Stock, 6%
STRYPES Due June 1, 1999" of the Company. The aggregate number of STRYPES which
may be authenticated and delivered under this Supplemental Indenture is limited
to 9,775,000 with an issue price of $22.875 per STRYPES, or $223,603,125 in the
aggregate, except for STRYPES evidenced by STRYPES Certificates authenticated
and delivered upon registration of transfer of, or in exchange for, or in lieu
of, other STRYPES Certificates evidencing such STRYPES pursuant to Section 304,
305, 306 or 906 of the Principal Indenture.

     The STRYPES shall mature on June 1, 1999 (the "Maturity Date").  On the
Maturity Date, the STRYPES shall be paid and discharged as provided in Article
Three of this Supplemental Indenture.

     The STRYPES shall bear interest at the rate of $1.37 per STRYPES per annum
(or $.3425 per STRYPES per quarter), from May 29, 1996, or from the most recent
Interest Payment Date (as defined below) to which interest has been paid or
provided for, as the case may be, until the

                                       4
<PAGE>
 
Maturity Date or such earlier date on which such STRYPES is redeemed or the
issue price of such STRYPES is repaid in accordance with the provisions of the
Indenture.  Interest shall be payable in cash quarterly in arrears on March 1,
June 1, September 1 and December 1, beginning September 1, 1996, and on the
Maturity Date (each, an "Interest Payment Date"), to the Persons in whose names
the STRYPES are registered at the close of business on the last day (whether or
not a Business Day) of the calendar month immediately preceding such Interest
Payment Date (each, a "Regular Record Date").  Interest on the STRYPES shall be
computed on the basis of a 360-day year of twelve 30-day months.

     The interest on the STRYPES shall be payable and the Maturity Consideration
or Tax Event Redemption Price shall be deliverable or payable at the office or
agency of the Company in the Borough of Manhattan, The City of New York
maintained for such purpose and at any other office or agency maintained by the
Company for such purpose; provided, however, that at the option of the Company
payment of interest may be made by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register.

     From and after a Tax Event Date, the STRYPES will be redeemable at the
option of the Company, in whole but not in part, as provided in Article Four of
this Supplemental Indenture. The STRYPES are not subject to any sinking fund or
other mandatory redemption provisions. The STRYPES shall not be payable at the
option of the Holders prior to the Maturity Date.

     The STRYPES shall be issuable only in registered form without coupons.  The
STRYPES will be issued in any whole numbers.  No fractional STRYPES or scrip
representing fractional STRYPES shall be issued.

     SECTION 202.  Form of STRYPES.  The STRYPES shall be evidenced by
                   ---------------                                    
certificates ("STRYPES Certificates") in the form attached hereto as Exhibit A.


                                 ARTICLE THREE

                        PAYMENT AND DISCHARGE OF STRYPES

     SECTION 301.  Payment and Discharge on the Maturity Date.  On the Maturity
                   ------------------------------------------                  
Date, unless previously redeemed pursuant to Section 401 of Article Four, the
Company shall pay and discharge each STRYPES by delivering to the Holder thereof
a number of shares (such number of shares being hereinafter referred to as the
"Payment Rate") of Cox Common Stock determined in accordance with the following
formula (the "Payment Rate Formula"), subject to adjustment as a result of
certain dilution events relating to the Cox Common Stock as provided for in
Section 303 of this Article Three: (a) if the Maturity Price is greater than or
equal to $27.91 per share of Cox Common Stock (the "Threshold Appreciation
Price"), .8196 shares of Cox Common Stock per STRYPES, (b) if the Maturity Price
is less than the Threshold Appreciation Price but is greater than $22.875 per
share of Cox Common Stock (the "Initial Price"), a fractional share of Cox
Common Stock per STRYPES so that the value thereof (determined based on the
Maturity Price)

                                       5
<PAGE>
 
is equal to the Initial Price (such fractional share being calculated to the
nearest 1/10,000th of a share or, if there is not a nearest 1/10,000th of a
share, to the next higher 1/10,000th of a share) and (c) if the Maturity Price
is less than or equal to the Initial Price, one share of Cox Common Stock per
STRYPES.  The numbers of shares of Cox Common Stock per STRYPES specified in
clauses (a) and (c) of the Payment Rate Formula are hereinafter referred to as
the "Share Components".  No fractional shares of Cox Common Stock shall be
delivered on the Maturity Date as provided in Section 302 of this Article Three.

     The term "Maturity Price" means, subject to Section 303(a)(v) of this
Article Three, the sum of (A) the average Closing Price per share of Cox Common
Stock on the 20 Trading Days immediately prior to, but not including, the second
Trading Day preceding the Maturity Date and (B) the fair market value (as
determined by the Board of Directors of the Company, whose determination shall
be conclusive, and described in a resolution adopted with respect thereto) as of
the third Trading Day preceding the Maturity Date of the Distributed Assets, if
any, applicable to one share of Cox Common Stock. The term "Closing Price"
means, with respect to any security on any date of determination, the closing
sale price (or, if no closing price is reported, the last reported sale price)
of such security on the New York Stock Exchange (the "NYSE") on such date or, if
such security is not listed for trading on the NYSE on any such date, as
reported in the composite transactions for the principal United States
securities exchange on which such security is so listed, or if such security is
not so listed on a United States national or regional securities exchange, as
reported by the National Association of Securities Dealers, Inc. Automated
Quotation System, or, if such security is not so reported, the last quoted bid
price for such security in the over-the-counter market as reported by the
National Quotation Bureau or similar organization, or, if such bid price is not
available, the market value of such security on such date as determined by a
nationally recognized independent investment banking firm retained for this
purpose by the Company. The term "Trading Day" means, with respect to any
security the Closing Price of which is being determined, a day on which such
security (A) is not suspended from trading on any national or regional
securities exchange or association or over-the-counter market at the close of
business and (B) has traded at least once on the national or

                                       6
<PAGE>
 
regional securities exchange or association or over-the-counter market that is
the primary market for the trading of such security.

     SECTION 302.  No Fractional Shares.  No fractional shares or scrip
                   --------------------                                
representing fractional shares of Cox Common Stock shall be delivered on the
Maturity Date.  If more than one STRYPES shall be held at one time by the same
Holder, the number of full shares of Cox Common Stock which shall be delivered
in payment of such Holder's STRYPES shall be computed on the basis of the
aggregate number of STRYPES so held on the Maturity Date.  In lieu of any
fractional share of Cox Common Stock which would otherwise be deliverable upon
payment and discharge of any STRYPES on the Maturity Date, the Company, through
any applicable Paying Agent, shall make a cash payment in respect of such
fractional interest in an amount equal to the value of such fractional share at
the Maturity Price.

     SECTION 303.  Adjustment of Payment Rate Formula.
                   ---------------------------------- 

     (a) Adjustment for Distributions, Reclassifications, etc.  The Payment Rate
         -----------------------------------------------------                  
Formula shall be subject to adjustment from time to time as follows:

          (i)  If Cox shall:

               (A)   pay a stock dividend or make a distribution with respect to
     Cox Common Stock in shares of such stock;

               (B)  subdivide or split the outstanding shares of Cox Common
     Stock into a greater number of shares;

               (C)  combine the outstanding shares of Cox Common Stock into a
     smaller number of shares; or

               (D)  issue by reclassification of shares of Cox Common Stock any
     shares of common stock of Cox;

then, in any such event, the Payment Rate Formula shall be adjusted so that each
Holder of any STRYPES shall thereafter be entitled to receive, upon payment and
discharge of such STRYPES on the Maturity Date (as provided in Section 301 of
this Article Three) or upon redemption of such STRYPES on the Redemption Date
(as provided in Section 401 of Article Four), the number of shares of Cox Common
Stock which such Holder would have owned or been entitled to receive immediately
following any event described above had such STRYPES been paid and discharged or
redeemed immediately prior to such event or any record date with respect
thereto. Each such adjustment shall become effective at the opening of business
on the Business Day next following the record date for determination of holders
of Cox Common Stock entitled to receive such dividend or distribution in the
case of a dividend or distribution and shall become effective immediately after
the effective date in the case of a subdivision, split, combination or
reclassification. Each such adjustment shall be made successively.

                                       7
<PAGE>
 
          (ii)  If Cox shall, after the date hereof, issue rights or warrants to
all holders of Cox Common Stock entitling them to subscribe for or purchase
shares of Cox Common Stock (other than rights to purchase Cox Common Stock
pursuant to a plan for the reinvestment of dividends or interest) at a price per
share less than the then current market price of the Cox Common Stock, then in
each case the Payment Rate Formula shall be adjusted by multiplying each of the
Share Components in the Payment Rate Formula in effect immediately prior to the
date of issuance of such rights or warrants, by a fraction, the numerator of
which shall be the number of shares of Cox Common Stock outstanding on the date
of issuance of such rights or warrants, immediately prior to such issuance, plus
the number of additional shares of Cox Common Stock offered for subscription or
purchase pursuant to such rights or warrants, and the denominator of which shall
be the number of shares of Cox Common Stock outstanding on the date of issuance
of such rights or warrants, immediately prior to such issuance, plus the number
of additional shares of Cox Common Stock which the aggregate offering price of
the total number of shares of Cox Common Stock so offered for subscription or
purchase pursuant to such rights or warrants would purchase at such current
market price, which shall be determined by multiplying such total number of
shares by the exercise price of such rights or warrants and dividing the product
so obtained by such current market price.  Such adjustment shall become
effective at the opening of business on the Business Day next following the
record date for the determination of stockholders entitled to receive such
rights or warrants.  To the extent that shares of Cox Common Stock are not
delivered after the expiration of such rights or warrants, or if such rights or
warrants are not issued, the Payment Rate Formula shall be readjusted to the
Payment Rate Formula which would then be in effect had such adjustments for the
issuance of such rights or warrants been made upon the basis of delivery of only
the number of shares of Cox Common Stock actually delivered.  Each such
adjustment shall be made successively.  For purposes of this subparagraph (ii),
the term "current market price" shall mean the average Closing Price per share
of Cox Common Stock on the 20 Trading Days immediately prior to the date such
rights or warrants are issued; provided, however, if any event that would result
in another adjustment of the Payment Rate Formula pursuant to this Section
303(a) occurs during such 20-day period, the current market price as determined
pursuant to the foregoing shall be appropriately adjusted to reflect the
occurrence of such event.

          (iii)  If Cox shall pay a dividend or make a distribution to all
holders of Cox Common Stock of evidences of its indebtedness or other assets
(excluding any stock dividends or distributions referred to in subparagraph
(i)(A) above or any cash dividends that do not constitute Extraordinary Cash
Dividends (as defined in subparagraph (vi) below)) or shall issue to all holders
of Cox Common Stock rights or warrants to subscribe for or purchase any of its
securities (other than those referred to in subparagraph (ii) above) (any of the
foregoing evidences of indebtedness or other assets or rights or warrants being
referred to herein as the "Distributed Assets"), then in each such case, the
Payment Rate Formula shall be adjusted by multiplying each of the Share
Components in the Payment Rate Formula in effect on the record date referred to
below by a fraction, the numerator of which shall be the market price per share
of the Cox Common Stock on the record date for the determination of stockholders
entitled to receive such dividend or distribution or such rights or warrants,
and the denominator of which shall be such market price per share of Cox Common
Stock less the fair market value (as determined by the Board of Directors of the
Company, whose determination shall be conclusive, and described in a resolution
adopted with

                                       8
<PAGE>
 
respect thereto) as of such record date, of the portion of the Distributed
Assets so distributed applicable to one share of Cox Common Stock; provided,
however, that in the event that the then fair market value (as so determined) of
the portion of the Distributed Assets so distributed applicable to one share of
Cox Common Stock is equal to or greater than the market price per share of Cox
Common Stock as of such record date, in lieu of the foregoing adjustment, (A)
the Company shall reserve such Distributed Assets (or, in the case of
Distributed Assets of a kind described in (z) below, an amount in cash equal to
the fair market value thereof, determined in the manner and as of the date
described in clause (z) below) for delivery to the Holders of the STRYPES on the
Maturity Date or the Redemption Date and, on the Maturity Date or the Redemption
Date, shall deliver to each such Holder, in addition to the shares of Cox Common
Stock (or cash in lieu thereof) to which such Holder is otherwise entitled, (x)
in respect of that portion, if any, of the Distributed Assets consisting of
cash, the amount of such Distributed Assets consisting of cash which such Holder
would have received had such Holder held the aforementioned shares of Cox Common
Stock to which such Holder is otherwise entitled immediately prior to the record
date for the determination of stockholders entitled to receive such dividend or
distribution or such rights or warrants, without interest, plus (y) in respect
of that portion, if any, of the Distributed Assets consisting of securities for
which there is an actual or when issued trading market ("marketable
securities"), the amount of such Distributed Assets consisting of marketable
securities which such Holder would have received had such Holder held the
aforementioned shares of Cox Common Stock to which such Holder is otherwise
entitled immediately prior to the record date for the determination of
stockholders entitled to receive such dividend or distribution or such rights or
warrants, plus (z) in respect of that portion, if any, of the Distributed Assets
which are of a kind other than that described in clause (x) or (y) above, an
amount in cash equal to the fair market value (as determined by the Board of
Directors of the Company, whose determination shall be conclusive, and described
in a resolution adopted with respect thereto), as of the record date for
determination of stockholders entitled to receive such dividend or distribution
or such rights or warrants, of the Distributed Assets consisting of other assets
which such Holder would have received had such Holder held the aforementioned
shares of Cox Common Stock to which such Holder is otherwise entitled
immediately prior to such record date, without interest thereon, and (B) clause
(b) of the Payment Rate Formula shall be adjusted to provide that, if the
Maturity Price is less than the Threshold Appreciation Price but is greater than
the Initial Price, each Holder of STRYPES will receive for each STRYPES on the
Maturity Date a fractional share of Cox Common Stock per STRYPES so that the
value thereof (determined based on the Maturity Price), together with the value
of any Distributed Assets applicable thereto, is equal to the Initial Price.
Each such adjustment shall become effective on the opening of business on the
Business Day next following the record date for the determination of
stockholders entitled to receive such dividend or distribution or such rights or
warrants. To the extent that such dividend or distribution is not so paid or
made, the Payment Rate Formula shall be readjusted to the Payment Rate Formula
which would then be in effect if such dividend or distribution had not occurred.
Each such adjustment shall be made successively. For purposes of this
subparagraph (iii), the term "market price" shall mean the average Closing Price
per share of Cox Common Stock on the 20 Trading Days immediately prior to such
record date for the determination of stockholders entitled to receive such
dividend or distribution or such rights or warrants; provided, however, if any
event that would result in another adjustment of the Payment Rate Formula
pursuant to this Section 303(a) occurs during such 20-day period, the market
price as determined pursuant to the foregoing shall be appropriately adjusted to
reflect the occurrence of such event.

          (iv)  Any shares of Cox Common Stock issuable in payment of a dividend
shall be deemed to have been issued immediately prior to the close of business
on the record date for

                                       9
<PAGE>
 
such dividend for purposes of calculating the number of outstanding shares of
Cox Common Stock under subparagraph (ii) above.

          (v)  All adjustments to the Payment Rate Formula shall be calculated
to the nearest 1/10,000th of a share of Cox Common Stock (or if there is not a
nearest 1/10,000th of a share to the next lower 1/10,000th of a share).  No
adjustment in the Payment Rate Formula shall be required unless such adjustment
would require an increase or decrease of at least one percent therein; provided,
however, that any adjustments which by reason of this subparagraph are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment.  If an adjustment is made to the Payment Rate Formula
pursuant to subparagraph (i), (ii) or (iii) of this Section 303(a), an
adjustment shall also be made to the Maturity Price solely to determine which of
clauses (a), (b) or (c) of the Payment Rate Formula in Section 301 will apply on
the Maturity Date.  The required adjustment to the Maturity Price shall be made
by multiplying each of the Closing Prices used in determining the Maturity Price
by a fraction, the numerator of which shall be the Share Component in clause (c)
of the Payment Rate Formula immediately after such adjustment pursuant to
subparagraph (i), (ii) or (iii) and the denominator of which shall be the Share
Component in clause (c) of the Payment Rate Formula immediately before such
adjustment.  Each such adjustment shall be made successively.  This subparagraph
(v) shall be so used to adjust the definition of Maturity Price only as such
term is used for the first time in each of clauses (a), (b) and (c) of the
Payment Rate Formula.

          (vi)  For purposes of the foregoing, the term "Extraordinary Cash
Dividend" shall mean, with respect to any consecutive 12-month period, any cash
dividend with respect to Cox Common Stock the amount of which, together with the
aggregate amount of all other such cash dividends on the Cox Common Stock
occurring in such 12-month period, exceeds on a per share basis 10% of the
average of the Closing Prices per share of the Cox Common Stock over such 12-
month period, and for purposes of applying the formula set forth in subparagraph
(iii) above, the fair market value of such dividends being calculated pursuant
to such subparagraph (iii) shall be equal to (x) the aggregate amount of such
cash dividend together with the amounts of such other cash dividends occurring
in such period minus (y) the aggregate amount of such other cash dividends
occurring in such period for which a prior adjustment in the Payment Rate
Formula was previously made under this Section 303(a).  In making the
determinations required by the foregoing sentence, the amount of cash dividends
paid on a per share basis shall be appropriately adjusted to reflect the
occurrence during such period of any event described in this Section 303(a).

     (b) Adjustment for Consolidation, Merger or Other Reorganization Event.  In
         ------------------------------------------------------------------     
the event of (i) any consolidation or merger of Cox, or any surviving entity or
subsequent surviving entity of Cox (a "Cox Successor"), with or into another
entity (other than a merger or consolidation in which Cox is the continuing
corporation and in which the Cox Common Stock outstanding immediately prior to
the merger or consolidation is not exchanged for cash, securities or other
property of Cox or another corporation), (ii) any sale, transfer, lease or
conveyance to another corporation of the property of Cox or any Cox Successor as
an entirety or substantially as an entirety, (iii) any statutory exchange of
securities of Cox or any Cox Successor with another corporation (other than in
connection with a merger or acquisition) or

                                       10
<PAGE>
 
(iv) any liquidation, dissolution, winding up or bankruptcy of Cox or any Cox
Successor (any such event described in clause (i), (ii), (iii) or (iv), a
"Reorganization Event"), the Payment Rate Formula used to determine the amount
payable on the Maturity Date for each STRYPES will be adjusted to provide that
each Holder of STRYPES will receive for each STRYPES on the Maturity Date cash
in an amount equal to (a) if the Transaction Value (as defined below) is greater
than or equal to the Threshold Appreciation Price, .8196 multiplied by the
Transaction Value, (b) if the Transaction Value is less than the Threshold
Appreciation Price but greater than the Initial Price, the Initial Price and (c)
if the Transaction Value is less than or equal to the Initial Price, the
Transaction Value.  "Transaction Value" means (x) for any cash received in any
such Reorganization Event, the amount of cash received per share of Cox Common
Stock, (y) for any property other than cash or securities received in any such
Reorganization Event, an amount equal to the market value on the Maturity Date
of such property received per share of Cox Common Stock as determined by a
nationally recognized independent investment banking firm retained for this
purpose by the Company and (z) for any securities received in any such
Reorganization Event, an amount equal to the average Closing Price per unit of
such securities on the 20 Trading Days immediately prior to the second Trading
Day preceding the Maturity Date, multiplied by the number of such securities
received for each share of Cox Common Stock.  Notwithstanding the foregoing, in
the event that property or securities, or a combination of cash, on the one
hand, and property or securities, on the other, are received in such
Reorganization Event, the Company may, at its option, in lieu of delivering cash
as described above, deliver the amount of cash, securities and other property
received per share of Cox Common Stock in such Reorganization Event determined
in accordance with clause (x), (y) or (z) above, as applicable.  If the Company
elects to deliver securities or other property, Holders of the STRYPES will be
responsible for the payment of any and all brokerage and transaction costs upon
any subsequent sale of such securities or other property.  The kind and amount
of securities with which the STRYPES shall be paid and discharged after
consummation of such transaction shall be subject to adjustment as described in
paragraph (a) above following the date of consummation of such transaction.

     SECTION 304. Payment and Discharge With Cash.
                  -------------------------------

     Notwithstanding the provisions of Sections 301, 302 and 303 of this Article
Three, the Company may, at its option, in lieu of delivering shares of Cox 
Common Stock and any Distributed Assets applicable thereto, deliver cash in an 
amount (calculated to the nearest 1/100th of a dollar per STRYPES or, if there 
is not a nearest 1/100th of a dollar, then to the next higher 1/100th of a 
dollar) equal to the value of such number of shares of Cox Common Stock at the 
Maturity Price, plus the fair market value (as determined by the Board of 
Directors of the Company, which determination shall be conclusive, and described
in a resolution adopted with respect thereto) as of the third Trading Day 
preceding the Maturity Date of any such Distributed Assets applicable thereto. 
Such option, if exercised by the Company, must be exercised with respect to all 
shares of Cox Common Stock and Distributed Assets otherwise deliverable on the 
Maturity Date upon payment and discharge of all Outstanding STRYPES. In 
determining the amount of cash deliverable upon payment and discharge of the 
STRYPES in lieu of shares of Cox Common Stock and any Distributed Assets 
pursuant to the second preceding sentence, if more than one STRYPES shall be 
held at one time by the same Holder, the amount of cash which shall be delivered
to such Holder upon payment and discharge shall be computed on the basis of the 
aggregate number of STRYPES so held on the Maturity Date.

     SECTION 305.  Notice of Adjustments and Certain Other Events.
                   ---------------------------------------------- 

     (a) Whenever the Payment Rate Formula requires adjustment as herein
provided, the Company shall:

          (i)  forthwith compute the adjusted Payment Rate Formula in accordance
with Section 303 of this Article Three and prepare a certificate signed by an
officer of the Company setting forth the adjusted Payment Rate Formula, the
method of calculation thereof in reasonable detail, and the facts requiring such
adjustment and upon which such adjustment is based, which certificate shall be
conclusive, final and binding evidence of the correctness of the adjustment, and
file such certificate forthwith with the Trustee; and

          (ii)  within 10 Business Days following the occurrence of an event
that requires an adjustment to the Payment Rate Formula pursuant to Section 303
of this Article Three (or if the Company is not aware of such occurrence, as
soon as practicable after becoming so aware), provide written notice to the
Trustee and to the Holders of the STRYPES of the occurrence of

                                       11
<PAGE>
 
such event and a statement in reasonable detail setting forth the adjusted
Payment Rate Formula and the method by which the adjustment to the Payment Rate
Formula was determined, provided, that, in respect of any adjustment to the
Maturity Price required pursuant to Section 303(a)(v), such notice need only
disclose the factor by which each of the Closing Prices used in determining the
Maturity Price is to be multiplied in order to determine the Payment Rate on the
Maturity Date, it being understood that, until the Maturity Date, the Payment
Rate itself cannot be determined.

     (b) In case at any time while any of the STRYPES are outstanding the
Company receives notice that:

          (i)  Cox shall declare a dividend (or any other distribution) on or in
respect of the Cox Common Stock to which Section 303(a)(i) or (iii) shall apply
(other than any cash dividends and distributions, if any, paid from time to time
by Cox that do not constitute Extraordinary Cash Dividends);

          (ii)  Cox shall authorize the issuance to all holders of Cox Common
Stock of rights or warrants to subscribe for or purchase shares of Cox Common
Stock or of any other subscription rights or warrants;

          (iii)  there shall occur any conversion or reclassification of Cox
Common Stock (other than a subdivision or combination of outstanding shares of
such Cox Common Stock) or any consolidation, merger or reorganization to which
Cox is a party and for which approval of any stockholders of Cox is required, or
the sale or transfer of all or substantially all of the assets of Cox; or

          (iv)  there shall occur the voluntary or involuntary dissolution,
liquidation, winding up or bankruptcy of Cox;

then the Company shall promptly cause to be delivered to the Trustee and any
applicable Paying Agent and filed at the office or agency maintained for the
purpose of payment and discharge of STRYPES on the Maturity Date in the Borough
of Manhattan, The City of New York by the Trustee (or any applicable Paying
Agent), and shall promptly cause to be mailed to the Holders of STRYPES at their
last addresses as they shall appear in the Security Register, at least 10 days
before the date hereinafter specified (or the earlier of the dates hereinafter
specified, in the event that more than one is specified), a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution or grant of rights or warrants, or, if a record is not to be taken,
the date as of which the holders of Cox Common Stock of record to be entitled to
such dividend, distribution or grant of rights or warrants are to be determined,
or (y) the date, if known by the Company, on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation, winding up or
bankruptcy is expected to become effective.

                                       12
<PAGE>
 
     (c) On or prior to the sixth Business Day preceding the Maturity Date, the
Company will notify The Depository Trust Company and the Trustee and will
publish a notice in The Wall Street Journal or another daily newspaper of
national circulation stating whether the STRYPES will be paid and discharged
with shares of Cox Common Stock or cash (or any securities or other property
that may be delivered pursuant to Section 303(b) of this Article Three) on the
Maturity Date in accordance with Section 301 of this Article Three.

     SECTION 306.  Shares Free and Clear.  The Company hereby warrants that upon
                   ---------------------                                        
payment and discharge of a STRYPES on the Maturity Date pursuant to this
Supplemental Indenture, the Holder of a STRYPES shall receive all rights held by
the Company in the Maturity Consideration with which such STRYPES is at such
time payable and dischargeable pursuant to this Supplemental Indenture, free and
clear of any and all liens, claims, charges and encumbrances, other than any
liens, claims, charges and encumbrances which may have been placed on any
Maturity Consideration by the prior owner thereof prior to the time such
Maturity Consideration was acquired by the Company. Except as provided in
Section 501 of Article Five, the Company will pay all taxes and charges with
respect to the delivery of the Maturity Consideration delivered upon payment and
discharge of STRYPES hereunder. In addition, the Company further warrants that
any Maturity Consideration so delivered upon payment and discharge of STRYPES
hereunder shall be free of any transfer restrictions (other than such as are
solely attributable to any Holder's status as an affiliate of Cox).

     SECTION 307.  Cancellation of STRYPES Certificates.  Upon receipt by the
                   ------------------------------------                      
Trustee of a STRYPES Certificate delivered to it for payment and discharge of
the STRYPES evidenced thereby under this Article Three, the Trustee shall cancel
and dispose of the same as provided in Section 309 of the Principal Indenture.


                                  ARTICLE FOUR

                       SPECIAL REDEMPTION UPON TAX EVENT

     SECTION 401.  Special Redemption Upon Tax Event.    The STRYPES shall be
                   ---------------------------------                         
redeemable at the option of the Company, in whole but not in part, at any time
from and after the date (the "Tax Event Date") on which a Tax Event shall occur
at a price per STRYPES (the "Tax Event Redemption Price") equal to (a) an amount
of cash equal to the sum of (x) all accrued and unpaid interest on such STRYPES
to the date fixed for redemption (the "Redemption Date"), (y) the sum of all
interest payments on such STRYPES due after the Redemption Date and on or prior
to the Maturity Date and (z) $1.37, plus (b) a number of shares of Cox Common
Stock (or any cash, securities or other property that may be delivered pursuant
to Section 303(b) of Article Three), including any Distibuted Assets applicable
thereto, determined in accordance with the Payment Rate Formula, with the
Redemption Date being deemed to be the Maturity Date for purposes of calculating
the Maturity Price.

     A "Tax Event" means that Cox Enterprises, Inc. ("CEI") shall have delivered
to the Company an opinion from independent tax counsel experienced in such
matters to the effect that, as a result of (a) any amendment or proposed
amendment to, or change (including any

                                       13
<PAGE>
 
announced prospective change) or proposed change in, the laws (or any
regulations thereunder) of the United States or any taxing authority thereof or
therein or (b) any amendment to, or change in, an interpretation or application
of such laws or regulations by any legislative body, court, governmental agency
or regulatory authority, enacted, promulgated, introduced, issued or announced
or which interpretation is issued or announced or which action is taken, on or
after May 22, 1996, there is more than an insubstantial risk that a corporation
that sells or otherwise disposes of stock in another corporation on a date that
is after May 22, 1996 and that is on or prior to the Maturity Date would not be
permitted to specifically identify the stock sold or disposed of for purposes of
determining the amount of such corporation's gain or loss on the stock sold or
disposed of for United States Federal income tax purposes.

     SECTION 402.  Notice of Redemption.  The Company shall provide notice of
                   --------------------                                      
any call for redemption of STRYPES to Holders of record of the STRYPES not less
than 10 nor more than 30 calendar days prior to the related Redemption Date.
Such notice will state the following and may contain such other information as
the Company deems advisable: (a) the Redemption Date; (b) the place or places
where certificates for the STRYPES are to be surrendered for redemption and (c)
that interest will cease to accrue on the STRYPES on the Redemption Date (except
as otherwise provided in the Indenture). Any such notice will be provided by
mail, sent to each Holder of record of STRYPES at such Holder's address as it
appears on the Security Register, first class postage prepaid; provided,
however, that failure to give such notice or any defect therein shall not affect
the validity of the proceeding for redemption of any STRYPES except as to the
Holder to whom the Company has failed to give said notice or whose notice was
defective. At or prior to the mailing of such notice of redemption, the Company
will publish a public announcement of redemption in The Wall Street Journal or
another daily newspaper of national circulation.

     SECTION 403.  No Fractional Shares.  The Company will not be required to
                   --------------------                                      
deliver any fractional share of Cox Common Stock on the Redemption Date and, in
lieu thereof, will pay an amount in cash equal to the value of such fractional
share of Cox Common Stock based on the average Closing Price per share of Cox
Common Stock on the 20 Trading Days immediately prior to, but not including, the
second Trading Day preceding the Redemption Date.

     SECTION 404.  Deposit of Shares and Funds.  The Company's obligation to pay
                   ---------------------------                                  
the Tax Event Redemption Price upon redemption in accordance with Section 401 of
this Article Four shall be deemed fulfilled if, on or before a Redemption Date,
the Company shall irrevocably deposit, with a bank or trust company, or an
affiliate of a bank or trust company, having an office or agency in The City of
New York and having a capital and surplus of at least $50,000,000, or shall set
aside or make other reasonable provision for the delivery and payment of, such
number of shares of Cox Common Stock (or any cash, securities or other property
that may be delivered pursuant to Section 303(b) of Article Three), including
any Distributed Assets applicable thereto, and funds for payment of such Tax
Event Redemption Price as is required to be delivered and paid by the Company
pursuant to Section 401 of this Article Four upon the occurrence of such
redemption (and, if applicable, funds for payment of cash in lieu of the
issuance of fractional share amounts as provided by Section 403 of this Article
Four). Any interest accrued on such funds shall be paid to the Company from time
to time. Any shares of Cox Common Stock (or any cash, securities or other
property that may be delivered pursuant to Section 303(b) of Article Three),
including any Distributed Assets applicable thereto, and funds so deposited and
unclaimed at the end of two years from such Redemption Date shall be repaid and
released to the Company, after

                                       14
<PAGE>
 
which the Holder or Holders of such STRYPES called for redemption shall look
only to the Company for delivery of such shares of Cox Common Stock (or any
cash, securities or other property that may be delivered pursuant to Section
303(b) of Article Three), including any Distributed Assets applicable thereto,
and funds.

     SECTION 405.  Surrender of Certificates; Rights of Holder.  Each Holder of
                   -------------------------------------------                 
STRYPES shall surrender the STRYPES Certificates evidencing such STRYPES
(properly endorsed or assigned for transfer, if the Board of Directors of the
Company shall so require and the redemption notice shall so state) to the
Company at the place designated in the notice of such redemption and shall
thereupon be entitled to receive the Tax Event Redemption Price pursuant to
Section 401 of this Article Four following such surrender and on and following
such Redemption Date. If such notice of redemption shall have been given, and if
on the Redemption Date shares of Cox Common Stock (or any cash, securities or
other property that may be delivered pursuant to Section 303(b) of Article
Three), including any Distributed Assets applicable thereto, and funds necessary
for redemption shall have been irrevocably either set aside by the Company
separate and apart from its other funds or assets in trust for the account of
the Holders of STRYPES (and so as to be and continue to be available therefor)
or deposited with a bank or trust company or an affiliate thereof as provided
herein or the Company shall have made other reasonable provision therefor, then,
notwithstanding that the STRYPES Certificates evidencing any STRYPES shall not
have been surrendered, the STRYPES evidenced thereby shall be deemed no longer
outstanding, interest on the STRYPES shall cease to accrue on the Redemption
Date and all rights of a Holder of the STRYPES shall forthwith after such date
cease and terminate, except the right to receive the shares of Cox Common Stock
(or any cash, securities or other property that may be delivered pursuant to
Section 303(b) of Article Three), including any Distributed Assets applicable
thereto, and funds constituting the Tax Event Redemption Price (and cash in lieu
of any fractional share amount) deliverable and payable pursuant to Section 401
of this Article Four without interest upon surrender of their STRYPES
Certificates therefor (unless the Company defaults on the payment of such Tax
Event Redemption Price).


                                  ARTICLE FIVE

                                     TAXES

     SECTION 501.  Documentary, Stamp, Transfer or Similar Taxes.  The Company
                   ---------------------------------------------              
will pay any and all documentary, stamp, transfer or similar taxes that may be
payable in respect of the transfer and delivery of Cox Common Stock (or any
securities or other property that may be delivered pursuant to Section 303(b) of
Article Three), including any Distributed Assets applicable thereto, pursuant to
this Supplemental Indenture; provided, however, that the Company shall not be
required to pay any such tax which may be payable in respect of any transfer
involved in the delivery of Cox Common Stock (or any securities or other
property that may be delivered pursuant to Section 303(b) of Article Three),
including any Distributed Assets applicable thereto, in a name other than that
in which the STRYPES so paid and discharged were registered, and no such
transfer or delivery shall be made unless and until the Person requesting such
transfer has paid to the Company the amount of any such tax, or has established,
to the satisfaction of the Company, that such tax has been paid.

     SECTION 502.  Treatment of STRYPES.  The parties hereto hereby agree, and
                   --------------------                                       
each Holder of a STRYPES by its purchase of a STRYPES hereby agrees:

                                       15
<PAGE>
 
       (a) to treat, for all United States Federal, state and local tax
          purposes, each STRYPES as a unit (a "Unit") consisting of (A) a debt
          instrument (the "Debt Instrument") with a fixed principal amount
          unconditionally payable on the Maturity Date equal to the issue price
          of the STRYPES and bearing interest at the stated interest rate on the
          STRYPES and (B) a forward purchase contract (the "Forward Contract")
          pursuant to which the Holder is irrevocably committed to use the
          principal payment due on the Debt Instrument to purchase on the
          Maturity Date or upon redemption the Cox Common Stock which the
          Company is obligated to deliver at that time (subject to the Company's
          right to deliver cash with an equal value in lieu of the Cox Common
          Stock), which treatment will require, among other things, each Holder
          that is subject to United States Federal income tax in connection with
          its ownership of the STRYPES to include currently in income payments
          denominated as interest that are made with respect to the STRYPES in
          accordance with such Holder's regular method of tax accounting and to
          treat the Debt Instrument as having been issued with original issue
          discount in an amount equal to 1.4% of the issue price of the STRYPES;

       (b) in the case of purchases of STRYPES in connection with the original
          issuance thereof, (A) to allocate $22.555 of the entire initial
          purchase price of a STRYPES (i.e., the issue price of a STRYPES) to
          the Debt Instrument component and to allocate the remaining $.32 of
          the entire initial purchase price of a STRYPES to the Forward Contract
          component and (B) to treat such acquisition of the STRYPES by the
          Holder as a purchase of the Debt Instrument by the Holder for $22.555
          and the making of an initial payment by the Holder with respect to the
          Forward Contract of $.32;

       (c) in the case of purchases and sales of STRYPES subsequent to the
          original issuance thereof, the purchase price paid (or received) by a
          Holder will be allocated by the Holder between the Debt Instrument and
          the Forward Contract based upon their relative fair market values (as
          determined on the date of acquisition or disposition);

       (d) to file all United States Federal, state and local income, franchise
          and estate tax returns consistent with the treatment of each STRYPES
          as a Unit consisting of the Debt Instrument and the Forward Contract
          (in the absence of any change or clarification in applicable law, by
          regulation or otherwise, requiring a different characterization or
          treatment of the STRYPES).

                        AMENDMENT OF CERTAIN PROVISIONS
                           OF THE PRINCIPAL INDENTURE

<PAGE>
 
     SECTION 601.      Amendments Relating to the STRYPES.  The Principal
                       ----------------------------------                
Indenture is hereby amended, solely with respect to the STRYPES, as follows:

     (a) By deleting Section 308 of the Principal Indenture in its entirety and
inserting in its stead the following:

     "SECTION 308. Persons Deemed Owners.  Prior to due presentment of a STRYPES
     Certificate for registration of transfer of STRYPES evidenced thereby, the
     Company, the Trustee and any agent of the Company or the Trustee may treat
     the Person in whose name such STRYPES Certificate is registered as the
     owner of the STRYPES evidenced thereby for the purpose of receiving
     delivery or payment of the Maturity Consideration or Tax Event Redemption
     Price in respect of, and (subject to Sections 305 and 307) interest on,
     such STRYPES and for all other purposes whatsoever, whether or not such
     STRYPES be overdue, and neither the Company, the Trustee nor any agent of
     the Company or the Trustee shall be affected by notice to the contrary."

     (b) By deleting Section 501 of the Principal Indenture in its entirety and
inserting in its stead the following:

     "SECTION 501.  Events of Default.  "Event of Default", wherever used herein

     administrative or governmental body):

          (1) failure to deliver or pay the Maturity Consideration on the

     registered or certified mail, to the Company by the Trustee, or to the
     Company and the Trustee by the Holders of at least 10% of the aggregate
     issue price of the Outstanding STRYPES a written notice specifying such
     failure and requiring it to be remedied and stating that such notice is a
     "Notice of Default" hereunder; or

          (4) a court having jurisdiction in the premises shall enter a decree
     or order for relief in respect of the Company in an involuntary case under
     any applicable bankruptcy, insolvency or other similar law now or hereafter

     become due or shall take any corporate action in furtherance of any of the
     foregoing."

     (c) By deleting Section 502 of the Principal Indenture in its entirety and
inserting in its stead the following:

     "SECTION 502.  Acceleration of Maturity; Rescission and Annulment.  If an
     Event of Default (other than an Event of Default specified in Section
     501(4) or 501(5)) occurs and is continuing, then and in every such case the
     Trustee or the Holders of not less than 25% of the aggregate issue price of
     the Outstanding STRYPES may declare an amount equal to the issue price of
     all the STRYPES to be due and payable immediately, by a notice in writing
     to the Company (and to the Trustee if given by the Holders), and upon any
     such declaration such amount shall become immediately due and payable in
     cash.  If an Event of Default specified in Section 501(4) or 501(5) occurs,
     an amount equal to the issue price of all the STRYPES shall automatically,
     and without any declaration or other action on the part of the Trustee or
     any Holder, become immediately due and payable in cash.

     At any time after such a declaration of acceleration has been made or an
     Event of Default specified in Section 501(4) or 501(5) has occurred, and
     before a judgment or decree for payment of the money due has been obtained
     by the Trustee as hereinafter provided, the Holders of a majority of the
     aggregate issue price of the Outstanding STRYPES, by written notice to the
     Company and the Trustee, may rescind and annul such declaration or Event of
     Default and its consequences if

          (1) the Company has paid or deposited with the Trustee a sum
          sufficient to pay

               (A) all overdue installments of interest on all STRYPES,

               (B) to the extent that payment of such interest is lawful,
               interest upon overdue installments of interest at the rate borne
               by the STRYPES, and

               (C) all sums paid or advanced by the Trustee hereunder and the
               reasonable compensation, expenses, disbursements and advances of
               the Trustee, its agents and counsel,

          (2) all Events of Default with respect to the STRYPES, other than the
          non-payment of the amount equal to the issue price of all the STRYPES
          due solely by reason of such declaration of acceleration or Event of
          Default specified in Section 501(4) or 501(5), have been cured or
          waived as provided in Section 513.

     No such rescission shall affect any subsequent default or impair any right
     consequent thereon."

     (d) By deleting the first paragraph of Section 503 of the Principal
Indenture in its entirety and inserting in its stead the following:

          "The Company covenants that, if default is made in the payment of any
     installment of interest on any STRYPES (other than interest due on the
     Maturity Date) when such interest becomes due and payable and such default
     continues for a period of 30 days, the Company will, upon demand of the
     Trustee, pay to it, for the benefit of the Holders of such STRYPES, an
     amount equal to the issue price of all the STRYPES, the whole amount of
     interest then due and payable on such STRYPES and, to the extent that
     payment of such interest shall be legally enforceable, interest on any
     overdue interest, at the rate borne by the STRYPES, and, in addition
     thereto, such further amount as shall be sufficient to cover the costs and
     expenses of collection, including the reasonable compensation, expenses,
     disbursements and advances of the Trustee, its agents and counsel.

          The Company further covenants that, if the Maturity Consideration or
     any interest due on the Maturity Date is not delivered or paid in respect
     of any STRYPES on the Maturity Date or if the Tax Event Redemption Price is
     not delivered or paid in respect of any STRYPES on the Redemption Date, the
     Company will, upon demand of the Trustee, pay to it, for the benefit of the
     Holders of such STRYPES, the Maturity Consideration or Tax Event Redemption
     Price, as the case may be, then due and payable on such STRYPES, the whole
     amount of interest then due and payable on such STRYPES and, to the extent
     that payment of such interest shall be legally enforceable, interest on any
     Maturity Consideration or Tax Event Redemption Price, as the case may be,
     that is overdue and on any overdue interest, at the rate borne by the
     STRYPES, and, in addition thereto, such further amount as shall be
     sufficient to cover the costs and expenses of collection, including the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel."

     Trustee pursuant to this Article shall be applied in the following order,
     at the date or dates fixed by the Trustee and, in case of the distribution
     of such money on account of the Maturity Consideration, the Tax Event
     Redemption Price or interest, upon presentation of the

     relevant STRYPES Certificate and the notation thereon of the payment if
     only partially paid and upon surrender thereof if fully paid:

          FIRST: To the payment of all amounts due the Trustee under Section
     607;

          SECOND: To the payment of any amounts then due and unpaid on the
     STRYPES in respect of which or for the benefit of which such money has been
     collected, ratably, without preference or priority of any kind, according
     to the amounts due and payable on such STRYPES; and

          THIRD: The balance, if any, to the Person or Persons entitled
     thereto."

     (f) By deleting Section 508 of the Principal Indenture in its entirety and
inserting in its stead the following:

     Consideration and Interest.  Notwithstanding any other provision in this
     Indenture, the Holder of any STRYPES shall have the right, which is
     absolute and unconditional, to receive (subject to Section 502) payment of
     the Maturity Consideration or Tax Event Redemption Price in respect of and
     (subject to Sections 305 and 307) interest on such STRYPES and to institute
     suit for the enforcement of any such payment, and such right shall not be
     impaired without the consent of such Holder."

     (g) By deleting the first sentence of Section 513 of the Principal
Indenture in its entirety and inserting in its stead the following:

     the Outstanding STRYPES may on behalf of the Holders of all STRYPES waive
     any past default hereunder and its consequences, except a default

          (1) in the delivery or payment of the Maturity Consideration or the
     Tax Event Redemption Price or in the payment of interest on any STRYPES, or

          (2) in respect of a covenant or provision hereof which under Article
     Nine cannot be modified or amended without the consent of the Holder of
     each Outstanding STRYPES affected."

     (h) By deleting Section 801 of the Principal Indenture in its entirety and
inserting in its stead the following:

     "SECTION 801.  Consolidations and Mergers of the Company and Sales, Leases
     and Conveyances Permitted Subject to Certain Conditions.  The Company may
     consolidate with, or sell, lease or convey all or substantially all of its

     any such case, (i) either the Company shall be the continuing corporation,

Indenture in its entirety and inserting in its stead the following:

     "With the consent of the Holders of not less than 66-2/3% of the aggregate

     the Company and the Trustee, the Company, when authorized by a Board

     the STRYPES and this Indenture."

     (k) By deleting Section 1003 of the Principal Indenture in its entirety and

     "SECTION 1003.  Money for Security Payments to Be Held in Trust.  If the
     Company shall at any time act as its own Paying Agent, it will, on or
     before each due date of the Maturity Consideration or Tax Event Redemption
     Price in respect of, or interest on, any of the STRYPES, segregate and hold
     in trust for the benefit of the Persons entitled thereto consideration in
     an amount sufficient to deliver or pay the Maturity Consideration or Tax
     Event Redemption Price or a sum sufficient to pay the interest so becoming
     due until such consideration shall be delivered or paid to such Persons or
     otherwise disposed of as herein provided and will promptly notify the
     Trustee of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents, it will, prior
     to each due date of the Maturity Consideration or Tax Event Redemption
     Price in respect of, or interest on, any STRYPES, deposit with a Paying
     Agent consideration in an amount sufficient to deliver or pay the Maturity
     Consideration or Tax Event Redemption Price or a sum sufficient to pay the
     interest so becoming due, such consideration to be held as provided by the
     Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
     Company will promptly notify the Trustee of its action or failure so to
     act.

     The Company will cause each Paying Agent other than the Trustee to execute
     and deliver to the Trustee an instrument in which such Paying Agent shall
     agree with the Trustee, subject to the provisions of this Section, that
     such Paying Agent will (i) comply with the provisions of the Trust
     Indenture Act applicable to it as Paying Agent and (ii) during the

     STRYPES) in the making of any payment in respect of the STRYPES, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums held
     in trust by such Paying Agent as such.

     The Company may at any time, for any purpose, pay, or by Company Order
     direct any Paying Agent to pay, to the Trustee all sums held in trust by
     the Company or such Paying Agent, such sums to be held by the Trustee upon
     the same trusts as those upon which such sums were held by the Company or
     such Paying Agent; and, upon such payment by any Paying Agent to the
     Trustee, such Paying Agent shall be released from all further liability
     with respect to such money.

     the Company on Company Request, or (if then held by the Company) shall be
     discharged from such trust; and the Holder of such STRYPES shall
     thereafter, as an unsecured general creditor, look only to the Company for
     payment thereof, and all liability of the Trustee or such Paying Agent with
     respect to such trust consideration, and all liability of the Company as
     trustee thereof, shall thereupon cease; provided, however, that the Trustee
     or such Paying Agent, before being required to make any such repayment, may
     at the expense of the Company cause to be published once, in an Authorized
     Newspaper in each Place of Payment or to be mailed to Holders of the
     STRYPES, or both, notice that such consideration remains unclaimed and
     that, after a date specified therein, which shall not be less than 30 days
     from the date of such publication or mailing, any unclaimed balance of such
     consideration then remaining will be repaid to the Company."

                        Issue Price Per STRYPES: $22.875

     Merrill Lynch & Co., Inc., a Delaware corporation (hereinafter called the
"Company", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay and
discharge each STRYPES evidenced hereby on June 1, 1999 (the "Maturity Date")
(subject to the Company's right to redeem the STRYPES evidenced hereby, as
described on the reverse hereof) by delivering to
_____________________________________, or registered assigns, a number of shares
(such number of shares, the "Payment Rate") of common stock, par value $1.00 per
share ("Cox

Common Stock"), of Cox Communications, Inc. ("Cox") (or, in the event there
shall occur a Reorganization Event, cash, securities and/or other property in
lieu thereof) and any Distributed Assets applicable thereto determined in
accordance with the Payment Rate Formula (as defined below), and to pay interest
(computed on the basis of a 360-day year of twelve 30-day months) on such
STRYPES from May 29, 1996, or from the most recent Interest Payment Date to
which interest has been paid or provided for, on March 1, June 1, September 1
and December 1 in each year, beginning September 1, 1996, and on the Maturity
Date, at the rate of $1.37 per STRYPES per annum (or $.3425 per STRYPES per
quarter), until the Maturity Date or such earlier date on which such STRYPES is
redeemed or the Issue Price of such STRYPES is repaid in accordance with the
provisions described below. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in said Indenture,
be paid to the Person in whose name this STRYPES Certificate (or one or more
Predecessor STRYPES Certificates) is registered at the close of business on the
last day (whether or not a Business Day) of the calendar month immediately
preceding such Interest Payment Date (each a "Regular Record Date"). In any case
where such Interest Payment Date shall not be a Business Day, then
(notwithstanding any other provision of said Indenture or this STRYPES
Certificate) payment of such interest need not be made on such date, but may be
made on the next succeeding Business Day with the same force and effect as if
made on such date, and, if such payment is so made, no interest shall accrue for
the period from and after such date. Any such interest not so punctually paid or
duly provided for shall forthwith cease to be payable to the registered Holder
on the relevant Regular Record Date, and may be paid to the Person in whose name
this STRYPES Certificate (or one or more Predecessor STRYPES Certificates) is
registered at the close of business on a Special Record Date for the payment of
such interest to be fixed by the Trustee hereinafter referred to, notice whereof
shall be given to Holders of STRYPES not less than 10 days prior to such Special
Record Date, or may be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
STRYPES may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in said Indenture.

     The Payment Rate shall be determined in accordance with the following
formula (the "Payment Rate Formula"), subject to adjustment as a result of
certain dilution events relating to the Cox Common Stock as provided for in the
Indenture:  (a) if the Maturity Price (as defined below) is greater than or
equal to $27.91 per share of Cox Common Stock (the "Threshold Appreciation
Price"), .8196 shares of Cox Common Stock per STRYPES, (b) if the Maturity Price
is less than the Threshold Appreciation Price but is greater than $22.875 per
share of Cox Common Stock (the "Initial Price"), a fractional share of Cox
Common Stock per STRYPES so that the value thereof (determined based on the
Maturity Price) is equal to the Initial Price (such fractional share being
calculated to the nearest 1/10,000th of a share or, if there is not a nearest
1/10,000th of a share, to the next higher 1/10,000th of a share) and (c) if the
Maturity Price is less than or equal to the Initial Price, one share of Cox
Common Stock per STRYPES. Notwithstanding the foregoing, the Company may, at its
option, in lieu of delivering shares of Cox Common Stock and any Distributed
Assets applicable thereto, deliver cash in an amount equal to the value of such
number of shares of Cox Common Stock at the Maturity Price, plus the fair market
value (as determined by the Board of Directors of the Company, which
determination shall be conclusive, and described in a resolution adopted with
respect thereto) as of the third Trading Day preceding the Maturity Date of any
such Distributed Assets applicable thereto, all as provided in the Indenture.
Such number of shares of Cox Common Stock (or, in the event there shall occur a
Reorganization Event as provided in the Indenture, cash, securities and/or other
property in lieu thereof) and any Distributed Assets applicable thereto or, at
the Company's option, the amount of cash, in either case deliverable upon
payment and discharge hereof is

                                      A-2
<PAGE>
 
hereinafter referred to as the "Maturity Consideration."  The term "Maturity
Price" means, except as otherwise provided in the Indenture, the sum of (A) the
average Closing Price per share of Cox Common Stock on the 20 Trading Days
immediately prior to, but not including, the second Trading Day preceding the
Maturity Date and (B) the fair market value (as determined by the Board of
Directors of the Company, whose determination shall be conclusive, and described
in a resolution adopted with respect thereto) as of the third Trading Day
preceding the Maturity Date of the Distributed Assets applicable to one share of
Cox Common Stock.  The term "Closing Price" means, with respect to any security
on any date of determination, the closing sale price (or, if no closing price is
reported, the last reported sale price) of such security on the New York Stock
Exchange (the "NYSE") on such date or, if such security is not listed for
trading on the NYSE on any such date, as reported in the composite transactions
for the principal United States securities exchange on which such security is so
listed, or if such security is not so listed on a United States national or
regional securities exchange, as reported by the National Association of
Securities Dealers, Inc. Automated Quotation System, or, if such security is not
so reported, the last quoted bid price for such security in the over-the-counter
market as reported by the National Quotation Bureau or similar organization or,
if such bid price is not available, the market value of such security on such
date as determined by a nationally recognized independent investment banking
firm retained for this purpose by the Company.  The term "Trading Day" means,
with respect to any security the Closing Price of which is being determined, a
day on which such security (A) is not suspended from trading on any national or
regional securities exchange or association or over-the-counter market at the
close of business and (B) has traded at least once on the national or regional
securities exchange or association or over-the-counter market that is the
primary market for the trading of such security.

     Interest on the STRYPES evidenced hereby will be payable, and delivery of
the Maturity Consideration in payment of the STRYPES evidenced hereby on the
Maturity Date will be made, upon surrender of this STRYPES Certificate, at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, The City of New York, and payment of interest on the STRYPES
evidenced by this STRYPES Certificate (and, if the Company elects to deliver
cash in lieu of Cox Common Stock on the Maturity Date, the amount of cash
payable on the Maturity Date) will be made in such coin or currency of the
United States of America as at the time of payment is legal tender for payment
of public and private debts; provided, however, that at the option of the
Company payment of interest may be made by check mailed to the address of the
Person entitled thereto as such address shall appear on the Securities Register.

     ADDITIONAL PROVISIONS OF THIS STRYPES CERTIFICATE ARE CONTAINED ON THE
REVERSE HEREOF AND SUCH PROVISIONS SHALL HAVE THE SAME EFFECT AS THOUGH FULLY
SET FORTH IN THIS PLACE.

                Structured Yield Product Exchangeable for Stock
                          6% STRYPES Due June 1, 1999

        (Payable with Shares of Common Stock, par value $1.00 per share,
                          of Cox Communications, Inc.)


     This STRYPES Certificate evidences part of a duly authorized issue of
unsecured and unsubordinated debentures, notes or other evidences of senior
indebtedness (hereinafter called the "Securities") of the Company of the series
hereinafter specified, all such Securities issued and to be issued under an
indenture dated as of April 1, 1983 and restated as of April 1, 1987, as amended
and supplemented as of May 1, 1996, between the Company and Chemical Bank
(successor by merger to Manufacturers Hanover Trust Company), as Trustee (the
indenture dated as of April 1, 1983 and restated as of April 1, 1987, as
amended, restated and supplemented from time to time, the "Indenture"), to which
Indenture and all other indentures supplemental thereto reference is hereby made
for a statement of the rights and limitation of rights thereunder of the Holders
of the Securities and of the rights, obligations, duties and immunities of the
Trustee for each series of Securities and of the Company, and the terms upon
which the Securities are and are to be authenticated and delivered.  As provided
in the Indenture, the Securities may be issued in one or more series, which
different series may be issued in various aggregate principal amounts, may be
denominated in currencies other than U.S. Dollars (including composite
currencies), may mature at different times, may bear interest, if any, at
different rates, may be subject to different redemption provisions, if any, may
be subject to different sinking, purchase and analogous funds, if any, may be
subject to different covenants and Events of Default and may otherwise vary as
in the Indenture provided or permitted.  This STRYPES Certificate evidences
Securities of the series designated as Structured Yield Product Exchangeable for
Stock, 6% STRYPES Due June 1, 1999 (each, a "STRYPES").

     The STRYPES will be redeemable at the option of the Company, in whole but
not in part, at any time from and after the date (the "Tax Event Date") on which
a Tax Event (as defined below) shall occur at a price per STRYPES (the "Tax
Event Redemption Price") equal to (a) an amount of cash equal to the sum of (x)
all accrued and unpaid interest on such STRYPES to the date fixed for redemption
(the "Redemption Date"), (y) the sum of all interest payments on such STRYPES
due after the Redemption Date and on or prior to the Maturity Date and (z)
$1.37, plus (b) a number of shares of Cox Common Stock (or, in the event there
shall occur a Reorganization Event, cash, securities and/or other property in
lieu thereof), including any Distributed Assets applicable thereto, determined
in accordance with the Payment Rate Formula, with the Redemption Date being
deemed to be the Maturity Date for purposes of calculating the Maturity Price.

                                      A-5
<PAGE>
 
     A "Tax Event" means that CEI shall have delivered to the Company an opinion
from independent tax counsel experienced in such matters to the effect that, as
a result of (a) any amendment or proposed amendment to, or change (including any
announced prospective change) or proposed change in, the laws (or any
regulations thereunder) of the United States or any taxing authority thereof or
therein or (b) any amendment to, or change in, an interpretation or application
of such laws or regulations by any legislative body, court, governmental agency
or regulatory authority, enacted, promulgated, introduced, issued or announced
or which interpretation is issued or announced or which action is taken, on or
after May 22, 1996, there is more than an insubstantial risk that a corporation
that sells or otherwise disposes of stock in another corporation on a date that
is after May 22, 1996 and that is on or prior to the Maturity Date would not be
permitted to specifically identify the stock sold or disposed of for purposes of
determining the amount of such corporation's gain or loss on the stock sold or
disposed of for United States Federal income tax purposes.

     The STRYPES are not subject to any sinking fund or other mandatory
redemption provisions.  The STRYPES are not payable at the option of the Holders
prior to the Maturity Date.

     If an Event of Default with respect to the STRYPES, as defined in the
Indenture, shall occur and be continuing, then an amount equal to the issue
price of all the STRYPES may be declared immediately due and payable in cash in
the manner and with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the STRYPES under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of 66-2/3%
of the aggregate issue price of the Outstanding STRYPES.  The Indenture also
contains provisions permitting the Holders of a majority of the aggregate issue
price of the Outstanding STRYPES, on behalf of the Holders of all STRYPES, to
waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences with respect to
the STRYPES.  Any such consent or waiver by the Holder of this Security shall be
conclusive and binding upon such Holder and upon all future Holders of the
STRYPES evidenced by this STRYPES Certificate and of any STRYPES evidenced by a
STRYPES Certificate issued upon the transfer hereof or in exchange herefor or in
lieu hereof whether or not notation of such consent of waiver is made upon this
STRYPES Certificate.

     No reference herein to the Indenture and no provision of this STRYPES
Certificate or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to deliver or pay the interest on,
and Maturity Consideration in respect of, the STRYPES evidenced by this STRYPES
Certificate at the times, place and rate, and in the manner, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the STRYPES evidenced by this STRYPES Certificate are transferable on the
Security Register

of the Company, upon surrender of this STRYPES Certificate for registration of
transfer at the office or agency of the Company to be maintained for that
purpose in The City of New York, New York, or at any other office or agency of
the Company maintained for that purpose, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new STRYPES Certificates,
evidencing the same aggregate number of STRYPES, will be issued to the
designated transferee or transferees.

     No service charge shall be made for any such transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection with the registration of such transfer
or exchange, other than certain exchanges not involving any transfer.  Certain
terms used in this STRYPES Certificate which are defined in the Indenture have
the meanings set forth therein.

     This STRYPES Certificate shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York.  The Company,
the Trustee and any agent of the Company or the Trustee may treat the Person in
whose name this STRYPES Certificate is registered as the owner of the STRYPES
evidenced hereby for the purpose of receiving payment as herein provided and for
all other purposes, whether or not the STRYPES be overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

     Merrill Lynch & Co., Inc., a Delaware corporation (hereinafter called the
"Company", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay and
discharge each STRYPES evidenced hereby on June 1, 1999 (the "Maturity Date")
(subject to the Company's right to redeem the STRYPES evidenced hereby, as
described on the reverse hereof) by delivering to
_____________________________________, or registered assigns, a number of shares
(such number of shares, the "Payment Rate") of common stock, par value $1.00 per
share ("Cox Common Stock"), of Cox Communications, Inc. ("Cox") (or, in the
event there shall occur a 
<PAGE>
 
Reorganization Event, cash, securities and/or other property in lieu thereof)
and any Distributed Assets applicable thereto determined in accordance with the
Payment Rate Formula (as defined below), and to pay interest (computed on the
basis of a 360-day year of twelve 30-day months) on such STRYPES from May 29,
1996, or from the most recent Interest Payment Date to which interest has been
paid or provided for, on March 1, June 1, September 1 and December 1 in each
year, beginning September 1, 1996, and on the Maturity Date, at the rate of
$1.37 per STRYPES per annum (or $.3425 per STRYPES per quarter), until the
Maturity Date or such earlier date on which such STRYPES is redeemed or the
Issue Price of such STRYPES is repaid in accordance with the provisions
described below. The interest so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in said Indenture, be paid
to the Person in whose name this STRYPES Certificate (or one or more Predecessor
STRYPES Certificates) is registered at the close of business on the last day
(whether or not a Business Day) of the calendar month immediately preceding such
Interest Payment Date (each a "Regular Record Date"). In any case where such
Interest Payment Date shall not be a Business Day, then (notwithstanding any
other provision of said Indenture or this STRYPES Certificate) payment of such
interest need not be made on such date, but may be made on the next succeeding
Business Day with the same force and effect as if made on such date, and, if
such payment is so made, no interest shall accrue for the period from and after
such date. Any such interest not so punctually paid or duly provided for shall
forthwith cease to be payable to the registered Holder on the relevant Regular
Record Date, and may be paid to the Person in whose name this STRYPES
Certificate (or one or more Predecessor STRYPES Certificates) is registered at
the close of business on a Special Record Date for the payment of such interest
to be fixed by the Trustee hereinafter referred to, notice whereof shall be
given to Holders of STRYPES not less than 10 days prior to such Special Record
Date, or may be paid at any time in any other lawful manner not inconsistent
with the requirements of any securities exchange on which the STRYPES may be
listed, and upon such notice as may be required by such exchange, all as more
fully provided in said Indenture.

     The Payment Rate shall be determined in accordance with the following
formula (the "Payment Rate Formula"), subject to adjustment as a result of
certain dilution events relating to the Cox Common Stock as provided for in the
Indenture:  (a) if the Maturity Price (as defined below) is greater than or
equal to $27.91 per share of Cox Common Stock (the "Threshold Appreciation
Price"), .8196 shares of Cox Common Stock per STRYPES, (b) if the Maturity Price
is less than the Threshold Appreciation Price but is greater than $22.875 per
share of Cox Common Stock (the "Initial Price"), a fractional share of Cox
Common Stock per STRYPES so that the value thereof (determined based on the
Maturity Price) is equal to the Initial Price (such fractional share being
calculated to the nearest 1/10,000th of a share or, if there is not a nearest
1/10,000th of a share, to the next higher 1/10,000th of a share) and (c) if the
Maturity Price is less than or equal to the Initial Price, one share of Cox
Common Stock per STRYPES. Notwithstanding the foregoing, the Company may, at its
option, in lieu of delivering shares of Cox Common Stock and any Distributed
Assets applicable thereto, deliver cash in an amount equal to the value of such
number of shares of Cox Common Stock at the Maturity Price, plus the fair market
value (as determined by the Board of Directors of the Company, which
determination shall be conclusive, and described in a resolution adopted with
respect thereto) as of the third Trading Day preceding the Maturity Date of any
such Distributed Assets applicable thereto, all as provided in the Indenture.
Such number of shares of Cox Common Stock (or, in

cash, securities and/or other property in lieu thereof) and any Distributed
Assets applicable thereto or, at the Company's option, the amount of cash, in
either case deliverable upon payment and discharge hereof is hereinafter
referred to as the "Maturity Consideration." The term "Maturity Price" means,
except as otherwise provided in the Indenture, the sum of (A) the average
Closing Price per share of Cox Common Stock on the 20 Trading Days immediately
prior to, but not including, the second Trading Day preceding the Maturity Date
and (B) the fair market value (as determined by the Board of Directors of the
Company, whose determination shall be conclusive, and described in a resolution

                           MERRILL LYNCH & CO., INC.

                Structured Yield Product Exchangeable for Stock
                          6% STRYPES Due June 1, 1999

        (Payable with Shares of Common Stock, par value $1.00 per share,
                          of Cox Communications, Inc.)


     This STRYPES Certificate evidences part of a duly authorized issue of
unsecured and unsubordinated debentures, notes or other evidences of senior
indebtedness (hereinafter called the "Securities") of the Company of the series
hereinafter specified, all such Securities issued and to be issued under an
indenture dated as of April 1, 1983 and restated as of April 1, 1987, as amended
and supplemented as of May 1, 1996, between the Company and Chemical Bank
(successor by merger to Manufacturers Hanover Trust Company), as Trustee (the
indenture dated as of April 1, 1983 and restated as of April 1, 1987, as
amended, restated and supplemented from time to time, the "Indenture"), to which
Indenture and all other indentures supplemental thereto reference is hereby made
for a statement of the rights and limitation of rights thereunder of the Holders
of the Securities and of the rights, obligations, duties and immunities of the
Trustee for each series of Securities and of the Company, and the terms upon
which the Securities are and are to be authenticated and delivered.  As provided
in the Indenture, the Securities may be issued in one or more series, which
different series may be issued in various aggregate principal amounts, may be
denominated in currencies other than U.S. Dollars (including composite
currencies), may mature at different times, may bear interest, if any, at
different rates, may be subject to different redemption provisions, if any, may
be subject to different sinking, purchase and analogous funds, if any, may be
subject to different covenants and Events of Default and may otherwise vary as
in the Indenture provided or permitted.  This STRYPES Certificate evidences
Securities of the series designated as Structured Yield Product Exchangeable for
Stock, 6% STRYPES Due June 1, 1999 (each, a "STRYPES").

     The STRYPES will be redeemable at the option of the Company, in whole but
not in part, at any time from and after the date (the "Tax Event Date") on which
a Tax Event (as defined below) shall occur at a price per STRYPES (the "Tax
Event Redemption Price") equal to (a) an amount of cash equal to the sum of (x)
all accrued and unpaid interest on such STRYPES to the date fixed for redemption
(the "Redemption Date"), (y) the sum of all interest payments on such STRYPES
due after the Redemption Date and on or prior to the Maturity Date and (z)
$1.37, plus (b) a number of shares of Cox Common Stock (or, in the event there
shall occur a Reorganization Event, cash, securities and/or other property in
lieu thereof), including any Distributed Assets applicable thereto, determined
in accordance with the Payment Rate Formula, with the Redemption Date being
deemed to be the Maturity Date for purposes of calculating the Maturity Price.

                                       5
<PAGE>
 
     A "Tax Event" means that CEI shall have delivered to the Company an opinion
from independent tax counsel experienced in such matters to the effect that, as
a result of (a) any amendment or proposed amendment to, or change (including any
announced prospective change) or proposed change in, the laws (or any
regulations thereunder) of the United States or any taxing authority thereof or
therein or (b) any amendment to, or change in, an interpretation or application
of such laws or regulations by any legislative body, court, governmental agency
or regulatory authority, enacted, promulgated, introduced, issued or announced
or which interpretation is issued or announced or which action is taken, on or
after May 22, 1996, there is more than an insubstantial risk that a corporation
that sells or otherwise disposes of stock in another corporation on a date that
is after May 22, 1996 and that is on or prior to the Maturity Date would not be
permitted to specifically identify the stock sold or disposed of for purposes of
determining the amount of such corporation's gain or loss on the stock sold or
disposed of for United States Federal income tax purposes.

     The STRYPES are not subject to any sinking fund or other mandatory
redemption provisions.  The STRYPES are not payable at the option of the Holders
prior to the Maturity Date.

     If an Event of Default with respect to the STRYPES, as defined in the
Indenture, shall occur and be continuing, then an amount equal to the issue
price of all the STRYPES may be declared immediately due and payable in cash in
the manner and with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the STRYPES under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of 66-2/3%
of the aggregate issue price of the Outstanding STRYPES.  The Indenture also
contains provisions permitting the Holders of a majority of the aggregate issue
price of the Outstanding STRYPES, on behalf of the Holders of all STRYPES, to
waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences with respect to
the STRYPES.  Any such consent or waiver by the Holder of this Security shall be
conclusive and binding upon such Holder and upon all future Holders of the
STRYPES evidenced by this STRYPES Certificate and of any STRYPES evidenced by a
STRYPES Certificate issued upon the transfer hereof or in exchange herefor or in
lieu hereof whether or not notation of such consent of waiver is made upon this
STRYPES Certificate.

     No reference herein to the Indenture and no provision of this STRYPES
Certificate or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to deliver or pay the interest on,
and Maturity Consideration in respect of, the STRYPES evidenced by this STRYPES
Certificate at the times, place and rate, and in the manner, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the STRYPES evidenced by this STRYPES Certificate are transferable on the
Security Register of the Company, upon surrender of this STRYPES Certificate for
registration of transfer at the office or agency of the Company to be maintained
for that purpose in The City of New York, New York, or at any other office or
agency of the Company maintained for that purpose, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new STRYPES
Certificates, evidencing the same aggregate number of STRYPES, will be issued to
the designated transferee or transferees.

     No service charge shall be made for any such transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection with the registration of such transfer
or exchange, other than certain exchanges not involving any transfer.  Certain
terms used in this STRYPES Certificate which are defined in the Indenture have
the meanings set forth therein.

     This STRYPES Certificate shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York.  The Company,
the Trustee and any agent of the Company or the Trustee may treat the Person in
whose name this STRYPES Certificate is registered as the owner of the STRYPES
evidenced hereby for the purpose of receiving payment as herein provided and for
all other purposes, whether or not the STRYPES be overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

                               STRYPES AGREEMENT
                               -----------------

       THIS AGREEMENT is made as of this 22nd day of May, 1996, between MERRILL
LYNCH CAPITAL SERVICES, INC. ("MLCS"), a Delaware corporation and wholly-owned

     WHEREAS, ML & Co. has filed with the Securities and Exchange Commission
(the "SEC") a registration statement on Form S-3 (File No. 33-65135) and Post-

holders thereof a specified number of shares of Class A Common Stock, par value
$1.00 per share (the "Cox Common Stock"), of Cox Communications, Inc., a
Delaware corporation ("Cox"), or, at ML & Co.'s option, cash with an equal
value. The terms of the STRYPES permit ML & Co., from and after a Tax Event
Date, to redeem the STRYPES, in whole but not in part, at the Tax Event
Redemption Price (as such terms are defined in the Supplemental Indenture
referred to below), consisting of a specified number of shares of Cox Common
Stock and an amount of cash determined as set forth in the Supplemental
Indenture (such amount of cash payable upon redemption being hereinafter
referred to as the "Redemption Cash Component").

     WHEREAS, ML & Co. has agreed, pursuant to an underwriting agreement dated
the date hereof (the "Underwriting Agreement") among ML & Co., CEI and Merrill
Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated (the

amended and supplemented by the Eighth Supplemental Indenture, dated as of May
__, 1996 (the "Supplemental Indenture"), between ML & Co. and the Trustee,

     WHEREAS, in order to obtain the cash and/or shares of Cox Common Stock,
including any Distributed Assets required to be delivered to ML & Co. pursuant
to the Subsidiary STRYPES (the "Distributed Assets"), (or, in the event there
shall occur a Reorganization Event, cash, securities and/or other property in
lieu thereof) required to satisfy its obligations under the STRYPES, ML & Co.
has agreed to purchase from MLCS, and MLCS has agreed to sell to ML & Co., (i)
concurrent with the issuance and sale of the Initial STRYPES, an obligation of
MLCS in the form of Exhibit A hereto, the aggregate principal amount of which

STRYPES, less an amount equal to certain of ML & Co.'s expenses in connection
with the offering of the Initial STRYPES, and the payment terms (other than the
interest rate) of which will be identical to the payment terms of the Initial
STRYPES (the "Initial Subsidiary STRYPES") and (ii) concurrent with each
issuance and sale of any Option STRYPES, an additional obligation of MLCS in the
form of Exhibit A hereto, the aggregate principal amount of which will be equal

Subsidiary STRYPES"); the Initial Subsidiary STRYPES and each Option Subsidiary
STRYPES are hereinafter collectively referred to as the "Subsidiary STRYPES."

     WHEREAS, CEI, through its wholly-owned subsidiary Cox Holdings, Inc. ("Cox
Holdings"), owns a number of shares of Cox Common Stock in excess of the maximum
number that would be required by MLCS to satisfy its obligations under the

the event there shall occur a Reorganization Event, cash, securities and/or
other property in lieu thereof) that would be required by MLCS to pay and
discharge the Subsidiary STRYPES on the Maturity Date or redeem the Subsidiary
STRYPES on the Redemption Date, without taking into account any default with
respect to the Subsidiary STRYPES or any acceleration of the maturity of the
Subsidiary STRYPES resulting therefrom.  The number of shares of Cox Common
Stock, including any Distributed Assets, (or, in the event there shall occur a
Reorganization Event, such cash, securities and/or other property in lieu

     WHEREAS, CEI will initially place in escrow, pursuant to an Escrow
Agreement dated as of May 29, 1996 (the "Escrow Agreement"), among MLCS, CEI and
The First National Bank of Chicago, as escrow agent (the "Escrow Agent"), an
aggregate of 13,294,000 shares of Cox Common Stock.

     WHEREAS, CEI will agree, pursuant to a Collateral Agreement dated as of May

circumstances set forth therein, to pledge and grant to MLCS a first priority
lien on, and security interest in, and right to set off against, all of CEI's
right, title and interest in and to the shares of Cox Common Stock (or, in the
event there shall occur a Reorganization Event, cash, securities and/or other
property in lieu thereof) held thereunder.

     WHEREAS, the ownership, voting rights and rights to receive any dividends
or other distributions in respect of the Escrow Shares (as defined herein) shall

obligations under the Subsidiary STRYPES), CEI shall notify MLCS whether it will
exercise its option to require cash settlement pursuant to this Section 2.5.

     2.6.  Maturity Date Closing Condition.  If a Reorganization Event shall
           -------------------------------

Reorganization Event shall be conditioned upon such securities and/or other
property so delivered being (a) transferable after such delivery without
contemporaneous registration under the Securities Act of 1933, as amended (the
"1933 Act"), and (b) free of any transfer restrictions.  If the condition set
forth in the preceding sentence shall not be satisfied, then, notwithstanding
the provisions hereof, the parties respective obligations contained in clause

Maturity Date Closing in lieu of delivery of the Maturity Contract Shares as
provided in Section 2.5.

Agreement:

          (i) collectively by the Escrow Agent in the Maximum Share Escrow
     Account under the Escrow Agreement and by the Collateral Agent in the
     Maximum Share Collateral Account under the Collateral Agreement an
     aggregate number of shares of Cox Common Stock and any Distributed Assets
     (or, in the event there shall occur a Reorganization Event, cash,
     securities and/or other property in lieu thereof) at least equal to the
     maximum number of shares of Cox Common Stock and any Distributed Assets
     (or, in the event there shall occur a Reorganization Event, cash,
     securities and/or other property in lieu thereof) that would be required by
     MLCS to pay and discharge all Subsidiary STRYPES on the Maturity Date (the
     "Maximum Contract Shares"); and

          (ii) collectively by the Escrow Agent in the Periodic Payment Escrow
     Account under the Escrow Agreement and by the Collateral Agent in the
     Periodic Payment Collateral Account under the Collateral Agreement an
     aggregate number of shares of Cox Common Stock (or such other assets
     permitted by the Escrow Agreement and the Collateral Agreement) (the
     "Periodic Payment Shares" and, together with the Maximum Contract Shares,
     the "Escrow Shares") so that the fraction (expressed as a percentage)
     obtained by dividing (x) the sum of all Periodic Payments due and unpaid
     and to become due on or prior to the Maturity Date by (y) the total value
     of the Periodic Payment Shares then held by the Escrow Agent and the
     Collateral Agent, based upon the Closing Price at the end of each calendar
     month (the "Specified Percentage") at the date hereof shall be 50% and at

after such delivery, the total number of Escrow Shares held as collateral
pursuant to the terms of the Collateral Agreement is equal to the sum of (x) the
Applicable Percentage of the Periodic Payment Shares and (y) the Applicable
Percentage of the Maximum Contract Shares.  Each Applicable Percentage shall be
determined based upon the lower of the credit ratings assigned to the Senior
Debt by Moody's and S&P (or, if only one of Moody's or S&P has assigned a rating
to the Senior Debt, such rating) or a substitute rating agency or agencies as

the Closing hereunder, it will conduct its affairs so that compliance with its
obligations hereunder and under the Escrow Agreement and the Collateral
Agreement do not and will not result in any violation of its charter or by-laws
or conflict with or constitute a breach or default (or in any situation that,
with the giving of notice or the passage of time, or both, would result in
default) in the performance or observance of any obligation, agreement, covenant
or condition contained in any contract, indenture, mortgage, deed of trust, loan
or credit agreement, note, lease or other agreement or instrument to which CEI
is a party or by which it may be bound or to which any of the property or assets

                                       10
<PAGE>
 
          (i) to treat, for all United States Federal, state and local tax
     purposes, this Agreement as a unit (a "Unit") consisting of (A) a debt
     instrument (the "Debt Instrument") with a fixed principal amount
     unconditionally payable on the Maturity Date equal to the total Firm
     Consideration Amount and the Option Consideration Amount (the "Total
     Consideration Amount") payable by MLCS hereunder and bearing interest in an
     amount equal to the Periodic Payments and (B) a forward contract (the
     "Forward Contract") pursuant to which MLCS is irrevocably committed to use
     the principal payment due on the Debt Instrument to purchase on the
     Maturity Date or the Early Settlement Date Closing the Contract Shares
     which CEI is obligated to deliver at that time (subject to CEI's right to
     deliver cash with an equal value in lieu of the Contract Shares), which
     treatment will require, among other things, MLCS to include currently in
     income as ordinary interest the Periodic Payments that are made under this
     Agreement by CEI in accordance with MLCS's regular method of tax
     accounting and to include in income as ordinary interest original issue
     discount in an amount equal to 1.4% of the Total Consideration Amount under
     a constant yield method.

          (ii) to allocate $185,932,485 of the Firm Consideration Amount to the
     Debt Instrument component and to allocate the remaining $2,640,015 of the
     Firm Compensation Amount to the Forward Contract component, and to allocate
     98.6% of the Option Consideration Amount to the Debt Instrument component
     and to allocate 1.4% of the Option Consideration Amount to the Forward
     Contract component;

          (iii)  to file all United States Federal, state and local income,
     franchise and estate tax returns consistent with the treatment of this
     Agreement as a Unit consisting of the Debt Instrument and the Forward
     Contract and consistent with the allocation described above in (ii) (in the
     absence of any change or clarification in applicable law, by regulation or
     otherwise, requiring a different characterization or treatment of this
     Agreement).

     6.5.  Amounts Due to Trustee. ML & Co. shall pay any and all amounts due to

notice of default with respect to the STRYPES received by ML & Co. from the
Trustee or any holders of STRYPES pursuant to the Indenture as promptly as

     respect of the Cox Common Stock to which Section 303(a)(i) or 303(a)(iii)
     of the Supplemental Indenture shall apply (other than any cash dividends
     and distributions, if any, paid from time to time by Cox that do not
     constitute Extraordinary Cash Dividends);

          (ii) Cox shall authorize the issuance to all holders of Cox Common
     Stock of rights or warrants to subscribe for or purchase shares of Cox
     Common Stock or of any other subscription rights or warrants;

          (iii)  there shall occur any conversion or reclassification of Cox
     Common Stock (other than a subdivision or combination of outstanding shares
     of such Cox Common Stock) or any consolidation, merger or reorganization to
     which Cox is a party and for which approval of any stockholders of Cox is
     required, or the sale or transfer of all or substantially all of the assets
     of Cox; or

          (iv) there shall occur the voluntary or involuntary dissolution,
     liquidation, winding up or bankruptcy of Cox;

date on which a record is to be taken for the purpose of such dividend,
distribution or grant of rights or warrants, or, if a record is not to be taken,
the date as of which the holders of Cox Common Stock of record to be entitled to
such dividend, distribution or grant of rights or warrants are to be determined,
or (y) the date, if known by CEI, on which such reclassification, consolidation,
merger, sale, transfer, dissolution, liquidation, winding up or bankruptcy is
expected to become effective.

           --------------------------------------------------------           
shall not, without the consent of MLCS and CEI, enter into any indenture
supplemental to the Indenture that would adversely affect any obligation of CEI
hereunder, including, without limitation, by increasing the consideration that
CEI is obligated to deliver at Closing pursuant to this Agreement.  ML & Co. and
CEI shall not, without the consent of CEI, amend the Subsidiary STRYPES in any
respect that would adversely affect any obligation of CEI hereunder, including,
without limitation, by increasing the consideration that CEI is obligated to
deliver at Closing pursuant to this Agreement.

     6.8.  Limitations on Trading During Certain Days.  Each of CEI and ML & Co.
           ------------------------------------------

Subsidiaries not to, buy or sell shares of Cox Common Stock for their own
account during the 20 Trading Days immediately prior to the second Trading Day
preceding the Maturity Date or any Redemption Date of the STRYPES (or, in the
case of a Tax Event (as defined in the Supplemental Indenture) that occurs less
than 20 Trading Days prior to a Redemption Date, during the period from and
after the occurrence of such Tax Event).  For purposes hereof, "Majority-Owned
Subsidiaries" with respect to either party means a subsidiary more than 50% of

under the STRYPES by delivering to the holders of the STRYPES on the Maturity
Date the form of consideration that it receives from MLCS under the Subsidiary
