PROMISE TO PAY. BOBBY ALLISON WIRELESS, INC. ("BORROWER") PROMISES TO PAY TO
SOUTHTRUST BANK, NATIONAL ASSOCIATION ("LENDER"), OR ORDER, IN LAWFUL MONEY OF
THE UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF THREE HUNDRED FIFTY
THOUSAND & 00/100 DOLLARS ($350,000.00), TOGETHER WITH INTEREST AT THE RATE OF
8.500% PER ANNUM ON THE UNPAID PRINCIPAL BALANCE FROM FEBRUARY 24, 1999, UNTIL
PAID IN FULL.

PAYMENT. BORROWER WILL PAY THIS LOAN IN 35 PAYMENTS OF $11,065.84 EACH PAYMENT
AND AN IRREGULAR LAST PAYMENT ESTIMATED AT $11,065,68. BORROWER'S FIRST PAYMENT
IS DUE MARCH 24, 1999, AND ALL SUBSEQUENT PAYMENTS ARE DUE ON THE SAME DAY OF
EACH MONTH AFTER THAT. BORROWER'S FINAL PAYMENT WILL BE DUE ON FEBRUARY 24,
2002, AND WILL BE FOR ALL PRINCIPAL AND ALL ACCRUED INTEREST NOT YET PAID.
PAYMENT INCLUDE PRINCIPAL AND INTEREST. The annual interest rate for this Note
is computed on a 365/360 basis; that is, by applying the ratio of the annual
interest rate over a year of 360 days, multiplied by the outstanding principal
balance, multiplied by the actual number of days the principal balance is
outstanding. Borrower will pay Lender at Lender's address shown above or at such
other place as Lender may designate in writing. Unless otherwise agreed or
required by applicable law, payments will be applied first to any unpaid
collection costs and any late charges, then to any unpaid interest, and any
remaining amount to principal.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount owed
earlier than it is due. Early payments will not, unless agreed to by Lender in
writing, relieve Borrower of Borrower's obligation to continue to make payments
of accrued unpaid Interest. Rather, they will reduce the principal balance due
and may result in Borrower making fewer payments.

LATE CHARGE. If a payment is 10 DAYS OR MORE LATE, Borrower will be charged
5.000% OF THE UNPAID PORTION OF THE REGULARLY SCHEDULED PAYMENT OR $.50,
WHICHEVER IS GREATER.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement related to this Note, or in any other agreement or loan Borrower
has with Lender. (c) Borrower defaults under any loan, extension of credit,
security agreement, purchase or sales agreement, or any other agreement, in
favor of any other creditor or person that may materially affect any of
Borrower's property or Borrower's ability to repay this Note or perform
Borrower's obligations under this Note or any of the Related Documents. (d) Any
representation or statement made or furnished to Lender by Borrower or on
Borrower's behalf is false or misleading in any material respect either now or
at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any guarantor dies or any of the other events described in this default
section occurs with respect to any guarantor of this Note. (h) A material
adverse change occurs In Borrower's financial condition, or Lender believes the
prospect of payment or performance of the Indebtedness is impaired. (i) LENDER
IN GOOD FAITH DEEMS ITSELF INSECURE.

If any default, other than a default in payment, is curable and if Borrower has
not been given a notice of a breach of the same provision of this Note within
the preceding twelve (12) months, it may be cured (and no event of default will
have occurred) if Borrower, after receiving written notice from Lender demanding
cure of such default: (a) cures the default within fifteen (15) days; or (b) if
the cure requires more than fifteen (15) says, immediately initiates steps which
Lender deems in Lender's sole discretion to be sufficient to cure the default
and thereafter continues and completes all reasonable and necessary steps
sufficient to produce compliance as soon as reasonably practical.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon default, including failure
to pay upon final maturity, Lender, at its option, may also, if permitted under
applicable law, do one or both of the following: (a) increase the interest rate
of this Note 5.000 percentage points, if and to the extent that the increase
does not cause the interest rate to exceed the maximum rate permitted by
applicable law, and (b) add any unpaid accrued Interest to principal and such
sum will bear Interest therefrom until paid at the rate provided In this Note
(including any increased rate). Lender may hire or pay someone else to help
collect this Note If Borrower does not pay. Borrower also will pay Lender the
amount of these costs and expenses, which Includes, subject to any limits under
applicable law, Lender's reasonable attorneys' fees and Lender's legal expenses
