     FOR VALUE RECEIVED, TEXAS BOTTLING GROUP, INC., a Nevada corporation
having its principal place of business located in Dallas, Texas (the
"Borrower"), hereby promises to pay to the order of _______________________
(the "Lender"), in its individual capacity, at the office of NATIONSBANK,
NATIONAL ASSOCIATION, as agent for the Lenders (the "Agent"), located at One
Independence Center, 101 North Tryon Street, NC1-001-15-04, Charlotte, North
Carolina 28255 (or at such other place or places as the Agent may designate
in writing) pursuant to the Credit Agreement dated as of March 11, 1998 among
the Borrower, the financial institutions party thereto (collectively, the
"Lenders") and the Agent (the "Agreement" -- all capitalized terms not
otherwise defined herein shall have the respective meanings set forth in the
Agreement), on the Revolving Credit Termination Date or such earlier date as
may be required pursuant to the terms of the Agreement, in lawful money of
the United States of America, in immediately available funds, the principal
amount of ___________ DOLLARS ($__________) or, if less than such principal
amount, the aggregate unpaid principal amount of all Loans made by the Lender
to the Borrower pursuant to the Agreement, and to pay interest from the date
hereof on the unpaid principal amount hereof, in like money, at said office,
on the dates and at the rates provided in ARTICLE II of the Agreement.  All
or any portion of the principal amount of Loans may be paid, reborrowed,
prepaid or required to be prepaid as provided in the Agreement.

     If payment of all sums due hereunder is accelerated under the terms of
the Agreement or under the terms of the other Loan Documents executed in
connection with the Agreement, the then remaining unpaid principal amount and
accrued but unpaid interest shall bear interest which shall be payable on
demand at the rates per annum set forth in the proviso to SECTION 2.2(a) of
the Agreement. Further, in the event of such acceleration, this Note shall
become immediately due and payable, without presentation, demand, protest or
notice of any kind, all of which are hereby waived by the Borrower.

     In the event this Note is not paid when due at any stated or accelerated
maturity, the Borrower agrees to pay, in addition to the principal and
interest, all costs of collection, including reasonable attorneys' fees, and
interest due thereon at the rates set forth above.

     Interest hereunder shall be computed as provided in the Agreement.

     This Note is one of the Notes referred to in the Agreement and is issued
pursuant to and entitled to the benefits and security of the Agreement to
which reference is hereby made for a more complete statement of the terms and
conditions upon which the Loans evidenced hereby were or are made and are to
be repaid.  This Note is subject to certain restrictions on transfer or
assignment as provided in the Agreement.

     All Persons bound on this obligation, whether primarily or secondarily
liable as principals, sureties, guarantors, endorsers or otherwise, hereby
waive to the full extent permitted by law (a) the benefits of all provisions
of law for stay or delay of execution or sale of property or other
satisfaction of judgment against any of them on account of liability hereon
until judgment be obtained and execution issues against any other of them and
returned satisfied or until it can be shown that the maker or any other party
hereto had no property available for the satisfaction of the debt evidenced
by this instrument, or until any other proceedings can be had against any of
them, and (b) their right, if any, to require the holder hereof to hold as
security for this Note any collateral deposited by any of said Persons as
security.  Except as otherwise expressly provided in the Loan Documents,
protest, notice of protest, notice of dishonor, diligence or any other
formality are hereby waived by all parties bound hereon.

     Notwithstanding any other provision herein, the aggregate interest rate
charged under this Revolving Note, including all charges or fees in
connection herewith deemed in the nature of interest under applicable law
shall not exceed the Highest Lawful Rate (as such term is defined below).  If
the rate of interest (determined without regard to the preceding sentence)
under the Agreement at any time exceeds the Highest Lawful Rate (as defined
below), the outstanding amount of the Loans made hereunder shall bear
interest at the Highest Lawful Rate until the total amount of interest due
hereunder equals the amount of interest which would have been due hereunder
if the stated rates of interest set forth in the Agreement had at all times
been in effect.  In addition, if, when the Loans made hereunder are repaid in
full, the total interest due hereunder (taking into account the increase
provided for above) is less than the total amount of interest which would
have been due hereunder if the stated rates of interest set forth in the
Agreement had at all times been in effect, then to the extent permitted by
law, the Borrower shall pay to the Agent an amount equal to the difference
between the amount of interest paid and the amount of interest which would
have been paid if the Highest Lawful Rate had at all times been in effect.
Notwithstanding the foregoing, it is the intention of the Lenders and the
Borrower to conform strictly to any applicable usury laws. Accordingly, if
any Lender contracts for, charges, or receives any consideration which
constitutes interest in excess of the Highest Lawful Rate, then any such
excess shall be cancelled automatically and, if previously paid, shall at
such Lender's option be applied to the outstanding amount of the Loans made
hereunder or be refunded to the Borrower.  As used in this paragraph, the
term "Highest Lawful Rate" means the maximum lawful interest rate, if any,
that at any time or from time to time may be contracted for, charged, or
received under the laws applicable to such Lender which are presently in
effect or, to the extent allowed by law, under such applicable laws which may
hereafter be in effect and which allow a higher maximum nonusurious interest
rate than applicable laws now allow.
