STATE OF TEXAS
COUNTY OF DALLAS

FOR VALUE RECEIVED, the undersigned DataVon, Inc., a Texas Corporation,
(hereinafter referred to as Maker) promises to pay to the order of J. Lee
Barton, an individual resident of the State of Georgia (hereinafter referred to
as Holder), in lawful money of the United States of America, the principal
amount of Two Million and 00/100 Dollars ($2,000,000.00), or so much as may be
outstanding, together with interest on the unpaid outstanding principal balance
of each advance. Interest shall be calculated from the date of each advance
until repayment of each advance or maturity, whichever occurs first.

Interest Rate:

Interest shall accrue on the unpaid balance of the principal at the rate of ten
percent (10%) per annum on all unpaid principal prior to maturity.

Payment:

Maker will pay this loan in two payments of all outstanding principal plus all
accrued unpaid interest. The first such payment shall be made 180 days after the
Loan Date described above. The second such payment shall be made 180 days after
the Subsequent Borrowing, as defined below (collectively, the "Maturity Dates").

Prepayment:



Maker shall have the right to prepay the principal in whole or in part on each
date when an installment is due as provided above, and interest shall
immediately cease to accrue, as of the date of payment, on any amount of
principal that is prepaid. Prepayments shall be applied first to accrued but
unpaid interest and then to the payment of installments next due under this
paragraph.

Security:

The obligations hereunder are secured pursuant to a Security Agreement (the
"Security Agreement") executed by the Maker and the Holder contemporanteously
herewith.

Post Maturity Rate:

The post maturity rate on this Note is the maximum rate allowed by applicable
law. Maker will pay interest at the post maturity rate on all sums due after the
Maturity Dates.

Default:

On the occurrence of a default under this Note as defined below, Holder may, at
Holder's election, by written notice to Maker at the address stated above
(unless changed by written notice to Holder), accelerate the maturity date by
declaring the entire unpaid balance of principal and any unpaid interest to be
immediately due and payable.

Waivers:

Maker, every surety, and every endorser of this Note severally waive demand,
presentment, notice of dishonor, diligence in collecting, grace, and notice of
protest, and agree to all renewals, extensions, and partial payments both before
and after maturity without prejudice to Holder.

Attorney's Fees:

If this Note is not paid at maturity and is placed in the hands of an attorney
for collection, or if it is collected through a court of bankruptcy, probate, or
other court after maturity, then Holder shall be entitled to reasonable
attorney's fees for collection.

Usury Exclusion:

All agreements between Maker and Holder are expressly limited so that in no
contingency or event shall the amount paid, or agreed to be paid, to Holder for
the use, forbearance, or



detention of the money to be loaned under this Note exceed the maximum amount
permissible under applicable law. If, from any circumstances whatsoever,
fulfillment of any provision of this Note at the time the performance is due
would exceed the usury limit prescribed by law, then the obligation to be
fulfilled shall be reduced to that limit. If from any circumstances Holder shall
receive as interest an amount that would exceed the highest lawful rate, the
amount that would be excessive interest shall be applied to the reduction of the
principal amount owing under this Note, or shall be refunded, but shall not be
applied to payment of interest. Without limiting the foregoing, all calculations
of the rate of interest taken, reserved, contracted for, charged, received or
provided for under this Note or the Security Agreement which are made for the
purpose of determining whether the interest rate exceeds the maximum rate under
applicable law shall be made, to the extent allowed by law, by amortizing,
prorating, allocating and spreading in equal parts during the period of the full
stated term of the loan evidenced hereby, all interest at any time taken,
reserved, contracted for, charged, received or provided for under this Note or
the Security Agreement.

two advances. Advances under this Note may be requested only in writing by Maker
