     FOR VALUE RECEIVED, the undersigned, CellStar Corporation, a Delaware
corporation ("Maker"), hereby promises to pay to the order of _________________
              -----
("Payee"), at the offices of The Chase Manhattan Bank, a New York banking
  -----

Deputy, on the dates hereinafter specified, in lawful money of the United States
of America, the principal sum of ____________ Dollars ($____________) or so much
thereof as may be advanced and outstanding hereunder, together with interest as
hereinafter specified.

     This Note is one of the Notes referred to in that certain Second Amended
and Restated Credit Agreement of even date herewith, among Maker, Payee, Agent,
and each of the banks or other financial institutions which is or may from time
to time become a signatory thereto and any successors or permitted assigns
thereof (as the same may be amended, modified, supplemented or restated from
time to time, being referred to herein as the "Agreement").  Capitalized terms
                                               ---------
used and not otherwise defined in this Note have the respective meanings
specified in the Agreement.

     The Agreement, among other things, contains provisions for acceleration of
the maturity of this Note upon the happening of certain stated events and also
for prepayments of Advances prior to the maturity of this Note upon the terms
and conditions specified in the Agreement.

     This Note is given in amendment, restatement and modification (but not in
extinguishment or novation) of the indebtedness evidenced by that certain
Revolving Credit Note dated August 2, 1999, executed by Maker and payable to the
order of Payee in the stated principal amount of $________, which Revolving
Credit Note was given in amendment, restatement and modification (but not
extinguishment or novation) of the indebtedness evidenced by that certain
Revolving Credit Note dated October 15, 1997, executed by maker and payable to
the order of Payee in the stated principal amount of $__________.

     This Note evidences Advances made by Payee to Maker under the Agreement.
Maker may borrow, repay and reborrow hereunder upon the terms and conditions
specified in the Agreement.

     The outstanding principal balance hereof shall bear interest at a varying
rate per annum which shall from day to day be equal to the lesser of (a) the
Maximum Rate, or (b) the Alternate Base Rate or the Adjusted LIBOR Rate, as
applicable in accordance with Section 2.8 of the Agreement (the "Applicable
                              -----------                        ----------
Rate"), each such change in the rate of interest charged hereunder to become
effective, without notice to Maker, on the effective date of each change in the
Applicable Rate or the Maximum Rate, as the case may be; provided, however, (i)
                                                         --------  -------
all outstanding principal of this Note and all past due interest hereon (to the
extent permitted by

REVOLVING CREDIT NOTE - Page 1
<PAGE>

applicable law) shall bear interest at the Default Rate when applicable as
specified in Section 2.8 of the Agreement, and (ii) if on any Interest Payment
Date, Payee does not receive payment in full of interest computed at the
Applicable Rate (computed without regard to any limitation by the Maximum Rate),
because the Applicable Rate (so computed) exceeds or has exceeded the Maximum
Rate applicable to Payee, Maker shall pay to Payee, in addition to interest
otherwise required, on each Interest Payment Date thereafter, the Excess
Interest Amount (calculated as of each such subsequent Interest Payment Date),
provided that in no event shall Maker be required to pay, for any computation
--------
period, interest at a rate exceeding the Maximum Rate applicable to Payee during
such period.

     Accrued and unpaid interest on this Note shall be due and payable on the
Interest Payment Dates. All principal of this Note shall be due and payable on
the Termination Date.

     Notwithstanding anything to the contrary contained herein, no provisions of
this Note shall require the payment or permit the collection of interest in
excess of the Maximum Rate. If any excess of interest in such respect is herein
provided for, or shall be adjudicated to be so provided, in this Note or
otherwise in connection with this loan transaction, the provisions of this
paragraph shall govern and prevail, and neither Maker nor the sureties,
guarantors, successors or assigns of Maker shall be obligated to pay the excess
amount of such interest, or any other excess sum paid for the use, forbearance
or detention of sums loaned pursuant hereto. If for any reason interest in
excess of the Maximum Rate shall be deemed charged, required or permitted by any
court of competent jurisdiction, any such excess shall be applied as a payment
and reduction of the principal of indebtedness evidenced by this Note; and, if
the principal amount hereof has been paid in full, any remaining excess shall
forthwith be paid to Maker. In determining whether or not the interest paid or
payable exceeds the Maximum Rate, Maker and Payee shall, to the extent permitted
by applicable law, (i) characterize any non-principal payment as an expense,
fee, or premium rather than as interest, (ii) exclude voluntary prepayments and
the effects thereof, and (iii) amortize, prorate, allocate, and spread in equal
or unequal parts the total amount of interest throughout the entire contemplated
term of the indebtedness evidenced by this Note so that the interest for the
entire term does not exceed the Maximum Rate.

     THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF TEXAS AND THE APPLICABLE LAWS OF THE UNITED STATES OF AMERICA. THIS
NOTE IS PERFORMABLE IN DALLAS COUNTY, TEXAS.

     Maker and each surety, guarantor, endorser, and other party ever liable for
payment of any sums of money payable on this Note jointly and severally waive
notice, presentment, demand for payment, protest, notice of protest and non-
payment or dishonor, notice of acceleration, notice of intent to accelerate,
notice of intent to demand, diligence in collecting, grace, and all other
formalities of any kind, except any notice and grace periods provided in the
Agreement, and consent to all extensions without notice for any period or
periods of time and partial payments, before or after maturity, and any
impairment of any Collateral securing this Note, all without prejudice to the
holder. The holder shall similarly have the right to deal in any way, at any
time, with one or more of the foregoing parties without notice to any other
party, and to grant any such party any extensions of time for payment of any of
said indebtedness, or to release or substitute part or all of the Collateral
securing this Note, or to grant any other

indulgences or forbearances whatsoever, without notice to any other party and
without in any way affecting the personal liability of any party hereunder.

     Maker hereby authorizes the holder hereof to endorse on the Schedule
attached to this Note or any continuation thereof or to record in its internal
records all Advances made to Maker hereunder and all payments made on account of
the principal thereof, which endorsements or records shall be prima facie
evidence as to the outstanding principal amount of this Note; provided, however,
any failure by the holder hereof to make any endorsement or record shall not
limit or otherwise affect the obligations of Maker under the Agreement or this
Note.

          payment of all amounts that constitute part of the Obligations and
          would be owed by the Borrower to the Agent or any Bank but for the

               desirable by the Agent to have caused the security interest
               created herein to be at all times fully perfected and in full
               force and effect with the priority required by this Agreement. No
               Debtor shall change its principal place of business, chief

               the end thereof, such section to read in its entirety as follows:

                    Section 1.4.   Changes in the UCC. All terms used herein

               which are defined in the UCC (hereinafter defined) shall, unless

               given such broadened meaning. If the UCC shall in the future be

               means the Uniform Commercial Code as in effect in the State of
               Texas or, if so required with respect to any particular
               Collateral by mandatory provisions of applicable law, as in
               effect in the jurisdiction in which such Collateral is located.

     (d)       Effective as of the date hereof, Section 2.4 of each of the
                                                ------------
