                         10% NOTE DUE DECEMBER 15, 2005

$_____________                                                Date _____________

         FOR VALUE RECEIVED, the undersigned VendingData Corporation, a Nevada
corporation ("Obligor"), hereby promises to pay to the order of
_______________or (his/her/its) registered assigns ("Holder") on December 15,
2005, the principal sum of ____________________Dollars ($_________ ) and to pay
interest on the unpaid principal balance hereof from the date hereof at a rate
of 10% per annum, payable semi-annually, in arrears, on June 1 and December 1,
until this Note is paid off and satisfied in full. Interest shall be calculated
on the basis of a 365/366-day year and actual days elapsed. Accrued but unpaid
interest shall not be compounded. The outstanding principal balance under this
Note and all accrued and unpaid interest shall be due and payable in a single
balloon payment on December 15, 2005. At its discretion, Obligor may, at any
time, redeem the Note without penalty upon payment of the face value of the Note
and any unpaid and accrued interest.

         Holder may convert up to 15% of the then outstanding principal amount
of this Note, at the Holder's option, and at any time after December 15, 2004
and until June 15, 2005 or before the prepayment of this Note, whichever shall
first occur, into shares of Obligor's common stock (the "Common Stock") at the
conversion price of $2.25 per share (the "Conversion Price"), post-reverse split
of 1-for-5. Upon surrender of this Note, duly endorsed or assigned to Obligor,
or in blank to Obligor, with the conversion notice attached hereto, or
accompanied by a separate written notice substantially in the form of such
conversion notice, duly executed by Holder and stating that the Holder elects to
convert up to 15% of the outstanding principal amount of this Note, Obligor
shall, as soon as practicable, deliver or cause to be delivered a certificate
for the number of full shares of Common Stock issuable upon the conversion and a
new promissory note representing the remaining unpaid principal amount and
accrued interest. The stock certificate(s) shall be registered in the name of
such Holder. If Obligor shall, prior to the conversion or payment of this Note

in full, (i) declare a dividend or make a distribution of its Common Stock
payable in shares of its Common Stock, (ii) subdivide its outstanding shares of
Common Stock into a greater number of shares of Common Stock, (iii) combine its
outstanding shares of Common Stock into a smaller number of shares of Common
Stock, or (iv) issue any shares of capital stock of Obligor by reclassification
or capital reorganization of its Common Stock, then the conversion privilege and
the Conversion Price in effect immediately prior to such action shall be
adjusted so that Holder shall be entitled to receive the number and kind of
shares of Common Stock or other capital stock which Holder would have owned or
have been entitled to receive immediately after such action had Holder converted
this Note immediately prior to the record date in the case of (i), or the
effective date in the case of (ii), (iii) or (iv).

         This Note is being issued as part of a Unit consisting of a Common
Stock Purchase Warrant (the "Warrant") to purchase up to One Hundred Twenty
Thousand (120,000), post-reverse split of 1-for-5, shares of Common Stock. This
Note and the Warrant are not detachable unless and until this Note is satisfied
and paid in full in accordance herewith. Exercise of certain rights under the
Warrant are expressly subject to certain conditions contained therein and
herein.

         This Note is secured pursuant to the terms of that certain Security
Agreement of even date herewith. The Holder agrees that all notices, demands,
consents and other rights of Holder are to be exercised pursuant to that certain
Irrevocable Power of Attorney of even date herewith.

         Obligor may not, without the prior written consent of Holder, issue
other indebtedness that has a senior ranking to this Note in priority of
payment. In the event any action is taken to collect or enforce the indebtedness
evidenced by this Note (the "Indebtedness") or any part thereof, Obligor agrees
to pay, in addition to the principal and interest due and payable hereon, all
costs of collecting this Note, including reasonable attorneys' fees and
expenses. These costs shall include any expenses incurred by Holder in any
bankruptcy, reorganization, or other insolvency proceeding.

         No delay or omission of Holder in exercising any right or rights, shall
operate as a waiver of such right or any other rights. A waiver on one occasion
shall not be construed as a bar to or waiver of any right or remedy on any
future occasion.

         The liability of Obligor under this Note (and the liability of any
endorsers of this Note) shall not be discharged, diminished or in any way
impaired by (a) any waiver by Holder or failure to enforce or exercise rights
under any of the terms, covenants or conditions of this Note, (b) the granting
of any renewal, indulgence, extension of time to Obligor, or any other obligors
of the Indebtedness, or (c) the addition or release of any person or entity
primarily or secondarily liable for the Indebtedness.

         In no event shall the interest rate charged or received hereunder at
any time exceed the maximum interest rate permitted under applicable law.
Payments of interest received by Holder hereunder which would otherwise cause
the interest rate hereunder to exceed such maximum interest rate shall, to the
extent of such excess, be deemed to be (and be deemed to have been contracted as
being) prepayments of principal and applied as such.

         This Note shall be binding upon the undersigned and its successors and
assigns and shall inure to the benefit of Holder and its successors and assigns.
Every person and entity at any time liable for the payment of this Note hereby
waives demand, presentment, protest, notice of protest, notice of nonpayment due
and all other requirements otherwise necessary to hold them immediately liable
for payment hereunder.

                                       2
