                            Revolving Promissory Note

                                                                     May 2, 2003

         1.       FOR VALUE RECEIVED, COX ENTERPRISES, INC., a Delaware
corporation ("Maker"), promises to pay ON DEMAND to the order of COX
COMMUNICATIONS, INC., a Delaware corporation ("Payee"), that certain principal
sum borrowed by Maker from Payee from time to time which shall be outstanding
and set forth on the grid attached hereto and made a part hereof (the "Grid") or
on any separate record thereof maintained by Payee. Interest shall accrue on the
principal hereof which shall be outstanding from time to time at the rate per
annum equivalent to the CEI Rate as defined herein, calculated daily and
compounded monthly (the applicable interest rate per annum at any given time
being hereinafter referred to as the "Interest Rate").

         2.       Any payment of principal or interest on this Revolving
Promissory Note which is not paid within five days of when due shall bear
interest at a rate per annum equal to 3.0% in excess of the Interest Rate until
paid, but only to the extent that payment of such interest on overdue principal
or interest is enforceable under applicable law. Payments of principal and
interest shall be made to Payee at 6205 Peachtree Dunwoody Road, Atlanta,
Georgia 30328, or at such other place as Payee may from time to time designate
in writing.

         3.       Payee shall enter all amounts of principal borrowed, paid or
prepaid at any time on the Grid or on any separate record thereof maintained by
Payee; provided, however, that the failure by Payee to so record amounts
borrowed and repaid under this Revolving Promissory Note shall in no way affect
the obligation of Maker to repay all amounts borrowed by Maker from Payee.

         4.       As used herein, the term "CEI Rate" shall mean the commercial
paper borrowing rate currently available to Maker in the commercial paper
market. For purposes of calculating interest hereunder, the CEI Rate in effect
at the close of business on each business day of Payee shall be the CEI Rate for
that day and any immediately succeeding nonbusiness day or days. In the event
the CEI Rate is not available, the holder hereof shall designate a comparable
reference rate as a substitute therefor.

         5.       Maker shall pay all amounts due hereunder, in cash, by
cashier's check or wire transfer of immediately available funds.

         6.       Maker shall have the right at any time to prepay the principal
hereof in full together with accrued interest thereon, in cash, by cashier's
check or wire transfer of immediately available funds, without prepayment
penalty.

         7.       In the event that this Revolving Promissory Note is collected
by or through an attorney-at-law, all reasonable costs of collection, including
reasonable attorneys' fees, shall be paid by Maker.

         8.       In no event shall the amount of interest due and payable under
this Revolving Promissory Note exceed the maximum rate of interest allowed by
applicable law (including,

<PAGE>

without limitation, Official Code of Georgia Annotated Section 7-4-18) and, in
the event any such payment is inadvertently made by Maker or inadvertently
received by Payee, such excess sum shall be credited as a payment of principal.
It is the express intent hereof that Maker not pay, and Payee not receive,
directly or indirectly or in any manner, interest in excess of that which may be
lawfully paid under applicable law.

         9.       Demand, presentment, notice, notice of demand, notice for
payment, protest and notice of dishonor are hereby waived by each and every
maker, guarantor, surety and other person or entity primarily or secondarily
liable on this Revolving Promissory Note, except as may be otherwise expressly
provided in the guaranty agreement of any guarantor.

         10.      Payee shall not be deemed to waive any of its rights hereunder
unless such waiver be in writing and signed by Payee. No delay or omission by
Payee in exercising any of its rights hereunder shall operate as a waiver of
such rights, and a waiver in writing on one occasion shall not be construed as a
consent to or a waiver of any right or remedy on any further occasion.

         11.      Time is of the essence with respect to this Revolving
Promissory Note.

         12.      This Revolving Promissory Note shall be governed by and
construed in accordance with the laws of the State of Georgia.

         IN WITNESS WHEREOF, Maker has caused this Revolving Promissory Note to
