and herein called the "Securities");

         WHEREAS,  the  Company,  in the  exercise  of the power  and  authority
conferred upon and reserved to it under the provisions of the Original Indenture
and pursuant to  appropriate  resolutions  of the Board of  Directors,  has duly
determined to make, execute and deliver to the Trustee this Second  Supplemental
Indenture to the Original Indenture in order to establish the form and terms of,

                              DEFINITIONS AND OTHER
                        PROVISIONS OF GENERAL APPLICATION

Section 101.      Definitions.

         Each  capitalized  term  that  is used  herein  and is  defined  in the
Original  Indenture shall have the meaning  specified in the Original  Indenture
unless such term is otherwise defined herein, in which case such term shall have
the meaning specified herein.

         "Additional Distribution" shall mean any distribution to Holders of the
Debentures  made  pursuant  to  Section  206 as a result  of a  Reference  Share
Distribution.

         "Adjusted  Principal  Amount"  shall  mean,  for each  $1,000  Original
Principal  Amount of the  Debentures,  $1,000,  minus any and all  Extraordinary
Additional  Distributions  and any Yield  Adjustments  made in  respect  to such
Original Principal Amount of Debentures pursuant to Section 204.

         "Average  Transaction  Consideration"  shall  mean,  with  respect to a
holder of one  Reference  Share in a Reference  Share Offer,  (a) the  aggregate
consideration  actually paid or distributed  in respect of all Reference  Shares
accepted  in such  Reference  Share  Offer,  divided by (b) the total  number of
Reference  Shares  outstanding  immediately  prior  to  the  expiration  of  the
Reference Share Offer and entitled to participate in such Reference Share Offer.

         "Business  Day"  shall mean any day that is not a  Saturday,  Sunday or
legal holiday,  on which banking  institutions or trust companies in The City of
New York are authorized or obligated by law or regulation to close.

         "Closing Price" shall mean, with respect to any security on any date of
determination, the closing sale price (or, if no closing sale price is reported,
the last  reported  sale price) of that  security  (regular way) on the New York
Stock Exchange on that date or, if the security is not listed for trading on the
New York Stock Exchange on that date, as reported in the composite  transactions
for the principal  United  States  national or regional  securities  exchange on
which the security is so listed, or if the security is not so listed on a United
States  national  or  regional  securities  exchange,  as reported by the Nasdaq
National  Market or, if the  security  is not so  reported,  the last quoted bid
price  for the  security  in the  over-the-counter  market  as  reported  by the
National Quotation Bureau or a similar  organization.  In the event that no such
quotation is available for that day, the Board of Directors  will be entitled to
determine  the Closing  Price on the basis of those  quotations  that it in good
faith  considers  appropriate,  unless  "Closing  Price" is to be determined for
purposes of valuing  securities to be distributed  pursuant to a Reference Share
Distribution and in the opinion of the Board of Directors there is a substantial
likelihood  that such  securities  will have an  aggregate  fair market value in
excess of $100,000,000, in which event the Closing Price will be determined by a
nationally  recognized  investment  banking or appraisal  firm  appointed by the
Company for such purpose. With respect to options,  warrants and other rights to
purchase a  security,  the Closing  Price  shall be the value of the  underlying
security determined as aforesaid,  minus the exercise price; and with respect to
securities
                                      -1-

exchangeable for or convertible into a relevant security, the Closing Price
shall be the Closing Price of the  exchangeable  or  convertible  security
determined  as aforesaid  or, if it has no Closing  Price,  the fully  converted
value based upon the Closing  Price of the  underlying  security  determined  as
aforesaid. If an "ex-dividend" date for a security occurs during the period used
in determining the security's Current Market Value or Exchange Market Value, the
Closing Price of the security on any day prior to the "ex-dividend" date used in
such  determination  shall be reduced by the  amount of the  dividend.  For this
purpose,  the amount of a non-cash  dividend  will be equal to the amount of the
dividend,  as of  the  record  date  therefor,  as  determined  by a  nationally
recognized  investment banking firm retained by the Company for this purpose. To
the extent that trading  (regular way) of, or quotations for, any security as to
which  "Closing  Price" is to be determined  continues  past 4:00 p.m., New York
City time, on the applicable securities exchange,  the National Market System or
over-the-counter  market, as the case may be, "Closing Price" shall be deemed to
refer to the price or bid at the time that is then customary for determining the
trading day's index levels for stocks traded on such  securities  exchange,  the
National Market System or over-the-counter market.

common stock or a Tracking Stock or participate  without  limitation in earnings
and  dividends in parity with such common stock or Tracking  Stock and (ii) that
are  Marketable  Securities.  For greater  certainty,  the term  "Common  Equity
Securities"  does not mean  warrants,  options or other rights to  purchase,  or
securities exchangeable or convertible into, Common Equity Securities.

         "Company"  shall mean the Person  named as the  "Company"  in the first
paragraph  of this  instrument  until a successor  Person shall have become such
pursuant to the applicable provisions of the Indenture, and thereafter "Company"
shall mean such successor Person, and any other obligor upon the Debentures.

         "Current Market Value" shall mean, with respect to any Reference Share,
the average of the Closing Prices for such  Reference  Share over the 20 Trading
Day  period  immediately  prior to (but not  including)  the fifth  Trading  Day
preceding the applicable Redemption Date (or, in the case of Section 204(b), the

the Company) to act as Exchange  Agent in addition to or in place of the Trustee
with respect to the Debentures.

         "Exchange Date" shall mean, with respect to any Notice of Exchange, the

received by the Exchange Agent.

         "Exchange   Market  Value"  shall  mean,  for  each   Reference   Share
attributable to the Debentures at the date of determination,  (a) in the case of
a Notice of Exchange  delivered to the  Exchange  Agent prior to March 14, 2002,

following  the Exchange  Date (unless more than  $1,000,000  aggregate  Original
Principal  Amount of Debentures have been validly  tendered for exchange on such
date, in which case Exchange  Market Value shall mean the average of the Closing
Prices for such  Reference  Share over the five Trading Day period ending on the
twentieth  Trading Day immediately  following the Exchange Date); and (b) in the
case of a Notice of Exchange  delivered to the Exchange  Agent on or after March

date,  in which case the  Exchange  Market  Value  shall mean the average of the
Closing  Prices  for such  Reference  Share  over the five  Trading  Day  period
immediately following the Exchange Date). The aggregate Exchange Market Value of

Values of the Reference Shares attributable to such Debenture.

         "Extraordinary  Additional  Distribution"  shall  mean  any  Additional
Distribution  other than a Regular Additional  Distribution,  whether of cash or
property;  provided that in the event of a Reference Share Offer,  the amount of

Consideration  deemed to be  received  on the  Reference  Shares of the class or
series  subject to the  Reference  Share Offer  attributable  to such  Debenture
(immediately  prior  to  giving  effect  to the  Reference  Share  Proportionate
Reduction  relating to that Reference Share Offer) other than the portion of the
Average  Transaction  Consideration  that consists of Common Equity  Securities,
which  themselves  become  part  of the  Reference  Shares  as a  result  of the
Reference Share Offer Adjustment.

         "Extraordinary   Distribution"   shall   mean   any   Reference   Share
Distribution other than a Regular Cash Dividend.

         "Final Period  Distribution"  shall mean, for each  Debenture,  (a) all
Regular Cash Dividends on any Reference  Shares  attributable  to such Debenture
for  which  the  ex-dividend  date  has  occurred  but  which,  at the  date  of
determination,  have not been received by the holders of such  Reference  Shares
and (b) all Extraordinary  Distributions on any Reference Shares attributable to
such  Debenture for which the  ex-dividend  date has occurred but which,  at the
date of  determination,  have not been received by the holders of such Reference
Shares,   but  only  to  the  extent  that  the  value  of  such   Extraordinary
Distributions  (determined in accordance with Section 206(d) or (e)) exceeds the
Adjusted Principal Amount of such Debenture.

Article Two

                        TITLE AND TERMS OF THE SECURITIES

Section 201.      Title of the Securities.

         The title of the  Securities  of the series  established  hereby is the
"Premium PHONES - 3% Exchangeable Subordinated Debentures due 2030."

Section 202.      Amount.

         The aggregate  Original Principal Amount of the Debentures which may be
authenticated  and  delivered  under  the  Indenture  is  initially  limited  to
$335,366,000,   except  for   Debentures   authenticated   and  delivered   upon
registration of transfer of, or in exchange for, or in lieu of, other Debentures
pursuant  to  Section  2.07,  2.08,  2.09  or 9.04  of the  Original  Indenture;
provided,  however,  that the  series of  Securities  established  hereby may be
reopened,  without  the consent of the Holders of  Outstanding  Debentures,  for
issuance of additional Debentures.

Section 203.      Registered Securities.

         The certificates for the Debentures shall be Registered  Securities and
shall be in substantially the forms attached hereto as Exhibit A, and shall bear
the legends as are inscribed thereon.

Section 204.      Stated Maturity; Changes to Original Principal Amount or
Adjusted Principal Amount.

(a) The Stated  Maturity of the principal of the  Debentures  shall be March 14,
2030.

(b) Not less than 30 Business Days prior to the Stated Maturity of the principal
of the Debentures, the Company shall issue a press release and provide it to DTC
for dissemination  through the DTC broadcast facility,  as to whether or not the
Company will deliver, or cause to be delivered, Reference Shares in exchange for
any Debentures submitted for exchange,  in

                                      -8-
<PAGE>

accordance with Section 209, from the date of such notice  through 5:00 p.m.,
New York City time,  on the Trading Day next preceding such Stated Maturity.
If Reference Shares are to be delivered in connection  with any such exchange,
Debentures  validly  exchanged  during that period,  in  accordance  with
Section 209,  will be exchanged  for the Reference Shares  attributable  to such
Debentures,  and the Company shall pay at Stated Maturity to Holders that do not
exchange  their  Debentures an amount,  in cash, determined in the same manner
as the  Redemption  Price is determined in Section 208(a)(ii)  (substituting
the term  "Stated  Maturity"  for  "Redemption  Date" therein), in full payment
for such Debentures. If Reference Shares are not to be delivered in connection
with any such exchange,  the exchange right set forth in Section  209 will
terminate  as of the 30th  Business  Day prior to the  Stated Maturity of the
principal of the  Debentures and the Company shall pay at Stated Maturity to
Holders of  Debentures  an amount,  in cash,  determined in the same manner  as
the   Redemption   Price  is  determined  in  Section   208(a)(i)(B)
(substituting the term "Stated Maturity" for "Redemption Date" therein), in full
payment for such  Debentures.  Any notice by the Company as to whether or not it
will  deliver  Reference  Shares in  exchange  for  Debentures  pursuant to this
Section 204(b) shall be irrevocable.

(c) The principal  amount of each Debenture  shall  initially equal the Original
Principal Amount.  Thereafter, the principal amount of each Debenture, as of any
date of determination, shall equal the Adjusted Principal Amount. In calculating
the Adjusted  Principal Amount,  (i) the value of any  Extraordinary  Additional
Distribution  shall be subtracted as of the date it is distributed to holders of
the Debentures, and (ii) the amount of each Yield Adjustment shall be subtracted
on the Interest Payment Date to which such Yield Adjustment relates. In no event
will the Adjusted Principal Amount be less than zero.

(d) At least five Business Days prior to the Stated Maturity of the principal of
Debentures,  the Company shall deliver an Officers'  Certificate  to the Trustee
which: (i) sets forth the amount to be paid in accordance with Section 204(b) at
such Stated Maturity for each Debenture and for all Debentures then Outstanding,
(ii) sets forth a reasonably  detailed  calculation  of such amounts,  and (iii)
directs  the  Trustee  to adjust its  records  accordingly  and to  request  the
Depository  to adjust its records  accordingly.  At or prior to 10:00 a.m.,  New
York  City  time,  on the  date  of  Stated  Maturity  of the  principal  of the
Debentures,  the Company  shall  deposit with the Trustee or with a Paying Agent
(or, if the  Company is acting as its own Paying  Agent,  segregate  and hold in
trust as provided in Section 3.03 of the Original  Indenture)  an amount in cash
sufficient  to pay, in  accordance  with Section  204(b),  the amount due on all
Debentures that are Outstanding at 5:00 p.m., New York City time, on the date of
such Stated Maturity.

(e) In the event of an  acceleration  of maturity of the Debentures  pursuant to
Section  6.01 of the  Original  Indenture  (as  modified by Section 217 hereof),
there shall become immediately due and payable an amount equal to the sum of (1)
the  greater  of (a)  the  Adjusted  Principal  Amount  of the  Debentures  then
Outstanding   and  (b)  the  Current  Market  Value  of  the  Reference   Shares
attributable  to the  Debentures,  (2) any  accrued  and unpaid  interest on the
Debentures and (3) subject to Section 211, any Final Period  Distribution on the
Debentures, determined as if (i) in the case of an Event of Default specified in
clause (g) or (h) of Section  6.01 of the Original  Indenture,  the date of such
Event of Default were the Stated Maturity of the

                                      -9-
<PAGE>

principal of the Debentures and (ii) in the case of any other  Event of Default,
the date of  declaration  of acceleration were the Stated Maturity of the
principal of the Debentures.

Section 205.      Interest.

(a) The  Debentures  shall bear  interest  from March 14,  2000 or from the most
recent  Interest  Payment Date to which  interest has been paid or provided for,
payable  semiannually  on March  14 and  September  14 of each  year  (each,  an
"Interest Payment Date"), commencing September 14, 2000, to the Persons in whose
names the Debentures (or one or more  Predecessor  Securities) are registered at
the close of business on the March 1 or September 1 immediately  preceding  such
Interest Payment Date. Calculations of interest on each Debenture shall be based
on the  Original  Principal  Amount,  without  regard to changes in the Adjusted
Principal Amount.

(b)  Interest on the  Debentures  will accrue at the rate of 3% per annum of the
Original  Principal Amount,  without regard to changes in the Adjusted Principal
Amount, until the principal thereof is paid or made available for payment.

Section 206.      Additional Distributions.

(a) The Company shall distribute,  or cause to be distributed,  as an Additional
Distribution  to all Holders of  Debentures,  any Reference  Share  Distribution
received  by  holders  of  Reference  Shares,  or the  cash  value  thereof,  in
accordance with this Section 206.

(b) In the case of any Regular  Cash  Dividend,  the  Company  shall pay, to the
Holder of each Debenture,  as a Regular Additional  Distribution,  the amount of
cash received by a holder of the number of Reference Shares attributable to such
Debenture in respect of such Regular Cash  Dividend.  Such payment shall be made
by the Company on the next Interest  Payment Date to Holders of Debentures as of
5:00 p.m.,  New York City time,  on the Regular  Record  Date for such  Interest
Payment Date.

(c) In the case of any Extraordinary Dividend, the Company shall deliver, to the
Holder of each  Debenture,  as an  Extraordinary  Additional  Distribution,  all
dividends and  distributions,  or the fair market value thereof  (determined  in
accordance  with Section  206(d) or (e)),  received by a holder of the number of
Reference Shares attributable to such Debenture in respect of such Extraordinary
Dividend.  Any distribution pursuant to this subsection (c) shall be made by the
Company to Holders of Debentures as of a special  record date which shall be the
10th  Business  Day  after  the  date  of  the  payment  of  the   Extraordinary
Distribution by the applicable  Reference  Company,  and shall be distributed to
such Holders on the 10th Business Day following such special record date.

(d) If an  Extraordinary  Distribution  consists of securities or units that are
Marketable  Securities  (other than securities  which are, or become,  Reference
Shares),  such securities or units will be distributed by the Company to Holders
of the Debentures in accordance with Section 206(c);  provided, that the Company
shall not  distribute  fractional  securities  or units.  In lieu of  fractional
securities  or units,  the Company shall pay the Holders of Debentures an amount
in cash equal to the  Closing  Price,  as of the  special  record  date,  of the
security or unit to be distributed  multiplied by such fractional interest.  For
purposes of determining  the existence of fractional  interests,  all Debentures
held by a Holder  shall be  considered  together  (no matter  how

                                      -10-
<PAGE>

many  separate certificates  such  Holder  may  have). In the event the  Company
is unable to distribute any  securities  or  units  as part of an  Extraordinary
Additional Distribution  because any  necessary  qualifications  or
registrations  of such securities or units under applicable state or federal
securities laws cannot be obtained on a timely  basis,  the Company may instead
deliver,  in lieu of such securities  or units, cash based on the average of the
Closing  Prices of such securities  or units over the five  Trading  Days ending
on the Trading Day next preceding  the  distribution  by the  Company of such
Extraordinary  Additional Distribution.

(e) If an Extraordinary  Distribution consists of cash, assets or property other
than securities or units that are Marketable  Securities,  the Company shall pay
to Holders of the  Debentures  an amount of cash equal to the fair market  value
thereof;  such  fair  market  value  to  be  determined  as  of  the  date  such
Extraordinary  Distribution  is  made  or  paid  to  holders  of the  applicable
Reference Shares. Such fair market value shall be equal to the amount determined
in good  faith  by the  Board  of  Directors,  unless  the  Board  of  Directors
determines  in good  faith  that  there  is a  substantial  likelihood  that the
aggregate  fair market  value will be in excess of  $100,000,000,  in which case
such fair market value shall be determined by a nationally recognized investment
banking or appraisal  firm  retained by the Company for this  purpose.  The fair
market value so determined  shall be set forth in a Board  Resolution or, in the
case of a determination by an investment banking or appraisal firm, an Officers'
Certificate.

(f) At  least  five  Business  Days  prior  to the  payment  or  delivery  of an
Extraordinary Additional Distribution by the Company pursuant to Section 206(c),
the Company  shall deliver to the Trustee a Board  Resolution  setting a special
record date for such  Extraordinary  Additional  Distribution  and an  Officers'
Certificate setting forth: (i) the exact amount of Marketable Securities or cash
to be distributed  on or with respect to the Reference  Shares  attributable  to
each Debenture, and (ii) the total amount of Marketable Securities or cash to be
distributed  on or with  respect to the  Reference  Shares  attributable  to all
Debentures  that  are  Outstanding  as of  such  special  record  date.  If  any
distribution  relates  to any  assets  or other  property  that is not  publicly
traded, then at least five Business Days prior to such distribution, the Company
shall  deliver to the  Trustee:  (A) a Board  Resolution  establishing  the fair
market value of the assets or other  property,  unless such fair market value is
determined by a nationally  recognized  investment banking or appraisal firm, in
which case the Company  shall deliver to the Trustee the report of such firm and
(B) an Officers'  Certificate  setting  forth (I) the exact amount of cash to be
distributed  on or with respect to the  Reference  Shares  attributable  to each
Debenture and (II) the total amount of cash to be distributed on or with respect
to the Reference  Shares  attributable to all Debentures that are Outstanding as
of such special  record date in respect of any assets or other  property that is
not publicly traded. The Trustee is only responsible for distributing Marketable
Securities in the form of global book entry securities that are DTC eligible. At
or  prior to  10:00  a.m.,  New York  City  time,  on the date an  Extraordinary
Additional  Distribution is to be made pursuant to Section  206(c),  the Company
shall (x) in the case of an Extraordinary  Additional Distribution consisting of
cash, deposit with the Trustee or with a Paying Agent an amount of cash equal to
the Extraordinary Additional Distribution to be paid on such date and (y) in the
case  of an  Extraordinary  Additional  Distribution  consisting  of  Marketable
Securities,  transfer  by  book-entry  to the account of the Trustee or a Paying
Agent at DTC (or any successor  Depository) the amount of Marketable  Securities
to be distributed in such  Extraordinary  Additional  Distribution on such date.
The Company shall act as its own Paying Agent for any  Marketable  Securities to
be delivered  other than  through  book-entry.  The Company  shall issue a

                                      -11-
<PAGE>

press release  setting  forth  the  amount  and  composition,  per  Debenture,
of any Extraordinary Additional Distribution and the Adjusted Principal Amount
thereof, and shall  deliver such press release to DTC for  dissemination
through the DTC broadcast facility.

Section 207.      Registration, Transfer and Exchange.

(a) The  principal  of and interest on the  Debentures  shall be payable and the
Debentures may be  surrendered  or presented for payment,  the Debentures may be
surrendered for registration of transfer or exchange, and notices and demands to
or upon the  Company in  respect  of the  Debentures  and the  Indenture  may be
served,  at the office or agency of the Company  maintained for such purposes in
The City of New York,  from time to time,  and the Company  hereby  appoints the
Trustee,  acting through its office or agency in The City of New York designated
from time to time for such  purpose,  as its agent for the  foregoing  purposes;
provided,  however, that at the option of the Company payment of interest on the
Debentures  may be made by check  mailed to the address of the Persons  entitled
thereto, as such addresses shall appear in the Security Register;  and provided,
further,  that (subject to Section 4.02 of the Original  Indenture)  the Company
may at any time  remove  the  Trustee as its office or agency in The City of New
York  designated for the foregoing  purposes and may from time to time designate
one or more other  offices or agencies for the  foregoing  purposes and may from
time to time rescind such designations.

Section 208.      Redemption of the Debentures.

(a) Optional Redemption.  The Debentures will be redeemable at the option of the
Company,  in whole or in part at any time or from time to time  after  March 17,
2004,  on at least 30 Business  Days (but not more than 60 days) prior notice to
Holders  of the  Debentures.  In the notice of  redemption,  the  Company  shall
specify  its  irrevocable  election of one of the  following  options  (each,  a
"Redemption Price"):

(i)      to terminate  Holders'  right to exchange,  in accordance  with Section
         209,  Debentures  called for redemption (but not affecting the exchange
         rights of Holders of any  Debentures  not  called for  redemption),  in
         which  case (A) no  further  exchange  of such  Debentures  called  for
         redemption  pursuant to Section 209 will be  permitted  on or after the
         30th  Business  Day  preceding  the  Redemption  Date  and  (B)  on the
         Redemption  Date, the Company shall pay Holders,  for each Debenture to
         be redeemed,  a Redemption  Price, in cash, equal to the sum of (1) the
         greater of (a) the Adjusted  Principal  Amount of such  Debenture as of
         the  Redemption  Date and (b) 100% of the Current  Market  Value of the
         Reference  Shares  attributable to such Debenture,  (2) any accrued and
         unpaid  interest  on such  Debenture  to the  Redemption  Date  and (3)
         subject  to  Section  211,  any  Final  Period   Distribution  on  such
         Debenture; or

(ii)     to  exchange  Debentures  surrendered  at  the  option  of  Holders  in
         accordance with Section 209, for Reference  Shares until 5:00 p.m., New
         York City time, on the Trading Day next preceding the Redemption  Date,
         in which case on the Redemption  Date the Company shall pay Holders who
         do not elect to exchange  Debentures for Reference Shares in accordance
         with Section  209(c),  for each Debenture to be redeemed,  a Redemption
         Price, in cash,  equal to the sum of (1) the Adjusted

                                      -12-
<PAGE>

         Principal Amount of such  Debenture at the  Redemption  Date, (2) any
         accrued and unpaid interest on such  Debenture to the  Redemption
         Date and (3) subject to Section 211, any Final Period Distribution on
         such Debenture.
(b) Notices.  In case of any redemption,  the Company shall deliver an Officers'
Certificate  to the  Trustee  not less  than  five  Business  Days  prior to the
Redemption  Date which sets forth (i) the  Redemption  Price to be paid for each
Debenture  called for redemption on such  Redemption Date and (ii) the aggregate
amount payable for all Debentures called for redemption on such Redemption Date.

(c)  Interest  Accrual to Cease.  Once notice of  redemption  has been given and
funds are  irrevocably  deposited  with the Trustee,  interest on the Debentures
will  cease to accrue on and after  the  Redemption  Date and all  rights of the
Holders of the Debentures called for redemption will cease, except for the right
of  Holders to receive  the  Redemption  Price  (but  without  interest  on such
Redemption Price) and any right to receive payment pursuant to Section 211.

(d) Payment  Failure.  In the event that the Company fails to pay any amount due
on redemption of the Debentures on a Redemption Date, interest on the Debentures
called for  redemption  shall  continue to accrue at an annual rate of 3% of the
Original Principal Amount thereof from the date originally set for redemption to
the actual date of payment,  and such actual date of payment  shall be deemed to
be the Redemption  Date for purposes of calculating the amount to be paid to the
Holders of Debentures on redemption,  except that the amount of the Final Period
Distribution shall be determined as of the date originally set for redemption.

Section 209.      Exchange of the Debentures.

(a) Each Debenture will be  exchangeable at the option of the Holder at any time
(except as otherwise  provided in subsection (f) below) for the Exchange  Market
Value of the Reference  Shares  attributable  to that  Debenture.  The number of
Reference Shares  attributable to each Debenture initially shall be 16.28 shares
of Sprint PCS Stock,  subject to adjustment  as a result of any Reference  Share
Proportionate  Reduction or any other adjustment  contemplated by the definition
of "Reference Shares."

(b) The Company  shall pay 100% of the Exchange  Market  Value of the  Reference
Shares  attributable to each Debenture,  only in cash, for all exchanges made on
or before the  Reference  Shares  Eligibility  Date.  On and after the Reference
Shares  Eligibility  Date,  the Company may, at its option,  (i) pay 100% of the
Exchange Market Value of the Reference Shares  attributable to each Debenture in
cash;  (ii)  deliver the  Reference  Shares  attributable  to such  Debenture in
payment  of such  Exchange  Market  Value;  or (iii)  deliver a  combination  of
Reference  Shares and cash. Such payment or delivery will be made as promptly as
practicable,  but in any  event  within  ten  Trading  Days  after  the  date of
determination  of the  Exchange  Market  Value.  The  Company  shall  notify the
Exchange  Agent of its election to pay cash or deliver  Reference  Shares,  or a
combination of the foregoing, by no later than 9:30 a.m., New York City time, on
the Trading Day next following the applicable  Exchange Date. The Exchange Agent
shall notify an exchanging  Holder of the Company's  election under this Section
209(b)  prior to 10:00 a.m.,  New York City time,  on the next Trading Day after
the Exchange Date.

                                      -13-
<PAGE>

(c) To exchange a  Debenture  a Holder must (a) in the case of a Debenture  held
through the Depository, surrender such Debenture for exchange through book-entry
transfer  into the account of the Exchange  Agent,  transmit an agent's  message
requesting such exchange and comply with such other procedures of the Depository
as may be  applicable  in the  case  of an  exchange  and  (b) in the  case of a
Debenture held in  certificated  form, (i) complete and manually sign the Notice
of Exchange  attached to the  Debenture (or complete and sign a facsimile of the
Notice of Exchange)  (and attached  hereto is Exhibit B) and deliver such Notice
of Exchange to the Exchange Agent,  (ii) surrender the Debenture to the Exchange
Agent,  (iii)  furnish  appropriate  endorsements  and  transfer  documents,  if
required  by the  Exchange  Agent,  the  Company or the Trustee and (iv) pay any
transfer or similar tax, if required.  An exchange  shall be deemed to have been
effected at 5:00 p.m., New York City time, on the Exchange Date. The delivery of
a  Notice  of  Exchange  or,  in the  case of  book-entry,  an  agent's  message
requesting  exchange,  shall be irrevocable.  A Holder may exchange a portion of
its Debentures  only if the portion is $1,000  Original  Principal  Amount or an
integral  multiple  thereof.  Following  the  Exchange  Date for an  exchange of
Debentures,  all rights of the Holder  with  respect  to such  Debentures  shall
cease,  except  for the  right  of such  Holder  to  receive  the  consideration
specified in Section 209(b) (but without interest thereon).

(d) By 10:00 a.m., New York City time, on each Trading Day following  receipt by
the  Exchange  Agent of  notification  from DTC that DTC has received an agent's
message from a DTC  participant  electing to exercise  its exchange  option with
respect to its  Debentures,  and delivery of such  Debentures  into the Exchange
Agent's DTC participant  account,  or following  receipt of a complete  manually
signed Notice of Exchange and receipt of certificated  Debentures from a Holder,
the  Exchange  Agent  shall  notify  the  Company  of the  principal  amount  of
Debentures  which has been  tendered.  When the  Exchange  Market Value has been
determined,  the Company shall deliver an Officers'  Certificate  to the Trustee
setting  forth the exact amount to be paid or the amount of Reference  Shares to
be  delivered  to the  tendering  Holder and shall  deposit such amount with the
Exchange Agent (except that if the Company elects to deliver Reference Shares in
certificated  form,  the  Company  shall act as its own Paying  Agent as to such
shares). Upon receipt of such payment or delivery from the Company, the Exchange
Agent shall pay DTC as soon as practicable  or, in the cases of Debentures  that
are held in certificated  form, as directed by the tendering  Holder.  Where the
Company  acts as its own Paying  Agent with  respect to  certificated  Reference
Shares,  it shall deliver them (i) as directed by the relevant  participants  of
the Depositary,  as identified by the Depositary, or (ii) to or at the direction
of tendering Holders of Debentures.

(e) In the case of any  exchange  made during the period from (but  excluding) a
Regular  Record  Date for any  Interest  Payment  Date to (but  excluding)  such
Interest  Payment Date,  the Holder shall tender funds equal to the interest and
any Additional Distribution payable on such Interest Payment Date.

(f) The  right  to  exchange  Debentures  pursuant  to this  Section  209  shall
terminate at 5:00 p.m., New York City time,  (i) in the case of Stated  Maturity
of the  principal  amount of the  Debentures,  on the  Trading  Day  immediately
preceding such Stated  Maturity and (ii) in the case of an optional  redemption,
on the Trading Day immediately  preceding the Redemption  Date. A Holder's right
to  exchange  Debentures  under  this  Section  209 shall  further be subject to
termination by the Company (i) in connection  with the payment of the Debentures
at Stated
                                      -14-
<PAGE>

Maturity,  during the period set forth in the penultimate  sentence of Section
206(b) and (ii) in  connection  with  optional  redemption,  during the period
set forth in  clause  (i) of  Section  208(a),  provided,  that any such
termination shall only apply to Debentures that have been called for redemption.

(g) If more than $1,000,000  aggregate  Original  Principal Amount of Debentures
are tendered for  exchange on any given date,  the Company  shall give notice of
such event to the Trustee and the Trustee  shall give notice  thereof to DTC for
distribution through its broadcast facility.

Section 210.      Distributions of Reference Shares or Other Securities.

(a) 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 Reference
Shares or in connection with an Extraordinary  Additional  Distribution pursuant
hereto;  provided,  however,  that the Company  shall not be required to pay any

of any and all liens,  claims,  charges and encumbrances,  other than any liens,
claims, charges and encumbrances which may have been placed thereon by the prior

Extraordinary Distribution referred to in subsection (a) above at the time or in
the amount  expected,  the Company  shall  pursue any claim it has against  such
Reference  Company,  whether as a securityholder or otherwise,  on behalf of the
Holders of  Debentures.  Reasonable  costs of

                                      -15-

Extraordinary   Distribution   before  any distribution is made to Holders of

be.

(c) The global  Debentures will be exchangeable for  certificated  Debentures of
like tenor and terms and of differing  authorized  denominations  aggregating  a

the Depository ceases to be a clearing agency under the Securities Exchange Act,
(iii) the Company in its sole discretion  determines that the global  Debentures
shall be  exchangeable  for  certificated  Debentures  or (iv) there  shall have
occurred and be continuing an Event of Default under the Indenture  with respect
to the Debentures.  Upon

Depository, as identified by the Depository.

        Premium PHONES - 3% Exchangeable Subordinated Debentures due 2030

         Cox Communications,  Inc., a Delaware  corporation  (hereinafter called
the "Company," which term includes any successor corporation under the Indenture
referred to below), for value received, hereby promises to pay to Cede & Co., or
registered   assigns,   the  amount  provided  in  Section  204  of  the  Second
Supplemental  Indenture referred to herein (such amount being referred to herein
as the Maturity  Repayment Amount) on March 14, 2030, and to pay interest on the
Original  Principal  Amount of this  Debenture  from March 14, 2000, or from the
most recent date to which  interest has been paid or provided for,  semiannually
on March 14 and September 14 in each year (each,  an "Interest  Payment  Date"),
commencing  September 14, 2000, at the rate of 3% per annum,  until the Maturity
Repayment  Amount  is paid or  made  available  for  payment.  Interest  on this
Debenture  shall be  calculated  on the basis of a 360-day  year  consisting  of
twelve  30-day  months.  The interest so payable and paid or provided for on any
Interest Payment Date will, as provided in such Indenture, be paid to the Person
in  whose  name  this  Debenture  (or one or  more  Predecessor  Securities)  is
registered  at the  close  of  business  on the  Regular  Record  Date  for such
interest,  which shall be the March 1 or  September 1 (whether or not a Business
Day), as the case may be, immediately  preceding such Interest Payment Date. Any
such interest which is payable, but is not paid or provided for, on any Interest
Payment Date shall forthwith cease to be payable to the registered Holder hereof
on the relevant  Regular  Record Date by virtue of having been such Holder,  and
may be  paid  to the  Person  in  whose  name  this  Debenture  (or  one or more
Predecessor  Securities)  is  registered  at the close of  business on a Special
Record  Date  for the  payment  of such  Defaulted  Interest  to be fixed by the
Company,  notice  whereof shall be given to

<PAGE>

the Holders of  Debentures  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 Debentures  may be
listed,  and upon such notice as may be required by such exchange, all as more
fully provided in such Indenture.

         Payment  of the  Maturity  Repayment  Amount and the  interest  on this
Debenture  will be made at the office or agency of the  Company  maintained  for
that  purpose in The City of New York,  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,
interest  may be paid by check  mailed to the  address  of the  Person  entitled
thereto  as such  address  shall  appear  in the  Security  Register;  provided,
further,  that payment to DTC or any  successor  Depository  may be made by wire
transfer  to the  account  designated  by DTC or such  successor  Depository  in
writing.

         This Debenture is one of a duly  authorized  issue of securities of the
Company (herein called the "Debentures")  issued and to be issued in one or more
series under an Indenture  dated as of June 27, 1995 (the "Original  Indenture,"
and together with the Second  Supplemental  Indenture  referred to below and all
other indentures  supplemental thereto, the "Indenture") between the Company and
The Bank of New York,  as  Trustee  (the  "Trustee",  which  term  includes  any
successor  trustee under the  Indenture),  to which Indenture and all indentures
supplemental  thereto reference is hereby made for a statement of the respective
rights,  limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the  Debentures,  and of the terms upon which the
Debentures are, and are to be,  authenticated  and delivered.  This Debenture is
one of the series  designated on the face hereof,  initially limited (subject to
exceptions provided in the Indenture) to the aggregate Original Principal Amount
specified  in the Second  Supplemental  Indenture  between  the  Company and the
Trustee,  dated as of March 14, 2000,  establishing  the terms of the Debentures
pursuant to the Indenture (the "Second Supplemental Indenture").

         The Debentures are, to the extent provided herein, in the Indenture and
in the  Second  Supplemental  Indenture,  subordinate  and  subject  in right of
payment to the prior payment in full of all Senior  Indebtedness  (as defined in
the  Second  Supplemental  Indenture),  and each  Holder  of this  Debenture  by
accepting the same,  agrees to and shall be bound by the provisions  hereof,  of
the Second Supplemental Indenture and of Article XII of the Original Indenture.

         The Debentures are redeemable at the option of the Company, in whole or
in part at any time or from  time to time on or after  March  17,  2004,  on the
terms set forth in Section 208(a) of the Second Supplemental Indenture.

         The Debentures are  exchangeable at the option of the Holders  thereof,
on the terms set forth in Section 209 of the Second Supplemental Indenture.

         If an Event of Default  (as  defined in the  Indenture,  including  the
amendments  thereto in the Second  Supplemental  Indenture)  with respect to the
Debentures shall occur and be continuing, the principal of the Debentures may be
declared  due and  payable in the manner  and with the  effect  provided  in the
Indenture.
<PAGE>

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

         No reference herein to the Indenture and no provision of this Debenture
or of the Indenture  shall alter or impair the obligation of the Company,  which
is absolute and unconditional, to pay the Maturity Repayment Amount and interest
on this  Debenture,  at the times,  place and rate, and in the coin or currency,
herein and in the Indenture prescribed.

         The Original  Indenture  contains  provisions for defeasance of (i) the
entire  indebtedness of the Debentures and (ii) certain  covenants and Events of
Default  with  respect  to the  Debentures,  in each case upon  compliance  with
certain  conditions set forth therein,  which  provisions shall not apply to the
Debentures. In addition,  provisions for certain covenants specified in Sections
4.08  and  4.09  of  the  Original  Indenture  shall  not be  applicable  to the
Debentures.

         As provided in the  Indenture  and subject to certain  limitations  set
forth  therein and in this  Debenture,  the  transfer of this  Debenture  may be
registered  on the  Security  Register  upon  surrender  of this  Debenture  for
registration  of transfer at the office or agency of the Company  maintained for
the purpose in any place where the  Maturity  Repayment  Amount and  interest on
this  Debenture  are  payable,  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 by his attorney duly authorized
in writing,  and thereupon one or more new Debentures of this series and of like
tenor, of authorized denominations and for the same aggregate Original Principal
Amount, will be issued to the designated transferee or transferees.

         The Debentures are issuable only in registered  form without coupons in
the denominations  specified in the Second Supplemental  Indenture  establishing
the terms of the  Debentures,  all as more fully provided in the  Indenture.  As
provided in the Indenture,  and subject to certain  limitations set forth in the
Indenture and in this  Debenture,  the  Debentures are  exchangeable  for a like
aggregate  Original  Principal  Amount of Debentures of this series in different
authorized denominations, as requested by the Holders surrendering the same.

         No service charge shall be made for any such  registration  of transfer
or exchange,  but the Company may require  payment of a sum  sufficient to cover
any tax or other governmental charge payable in connection therewith, other than
in certain cases provided in the Indenture.
<PAGE>

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

         This  Debenture  shall be governed by and construed in accordance  with
the laws of the State of New York.

         All terms used in this  Debenture  which are  defined  in the  Original
Indenture or the Second Supplemental  Indenture shall have the meanings assigned
to them in the  Original  Indenture  or the Second  Supplemental  Indenture,  as
applicable.

         Unless the certificate of authentication hereon has been executed by or
on behalf of the Trustee under the  Indenture by the manual  signature of one of
its authorized signatories, this Debenture shall not be entitled to any benefits
under the Indenture or be valid or obligatory for any purpose.
