into this 15 day of June 2001 by and between VendingData Corporation, a Nevada
corporation (the "Company"), and James E. Crabbe, an individual, or a designee
of James E. Crabbe (collectively, the "Purchaser").

                                 R E C I T A L S

         WHEREAS, the board of directors of the Company declared a distribution
of rights to purchase shares of common stock, par value $0.001 ("Common Stock"),
to stockholders of record as of June 15, 2001 (the "Record Date") and to holders
of certain options, warrants and convertible debentures that possess
anti-dilution rights as of the Record Date, where the qualified stockholders and
the qualified holders of options, warrants and convertible debentures are
referred to as "Rightsholders";

         WHEREAS, the Company proposes to grant to Rightsholders one right for
each share of Common Stock, or each share of Common Stock underlying the
options, warrants or convertible debentures, as applicable, that Rightsholders
own on the Record Date (the "Rights"), where each Right allows Rightsholders to
purchase two shares of Common Stock for $0.35 per share (the "Exercise Price");

         WHEREAS, pursuant to this distribution of the Rights, the Company
proposes to file a registration statement on Form S-3 with the Securities and
Exchange Commission ("the Commission") on approximately the second week of June
2001 (the "Registration Statement") in order to register approximately
26,769,770 shares of Common Stock that may be purchased upon exercise of all of
the Rights (the "Shares");

         WHEREAS, the Rights will expire if the Rightsholders have not exercised
the Rights and submitted the necessary documentation and payment for the Shares
before the expiration date, which is thirty (30) days after the effective date
of the Registration Statement (the "Expiration Date");

         WHEREAS, in the event that all of the Rightsholders do not exercise
their Rights by the Expiration Date, the Purchaser agrees to exercise the
remaining Rights and purchase the remaining shares of Common Stock underlying
the Rights (the "Standby Shares"); and

         WHEREAS, the issuance of the Rights, the offering of the Shares and the
subscription and purchase of the Shares upon the terms described in the
Prospectus (as hereinafter defined), including the purchase of the Standby
Shares pursuant to this Agreement, are herein collectively referred to as the
"Rights Offering."

         NOW, THEREFORE, in consideration of the several and mutual promises,
agreements, covenants, understandings, undertakings, representations and
warranties hereinafter set forth, and for other good and valuable consideration,
the receipt and sufficiency of which is hereby acknowledged, the parties agree
that the Recitals are true and correct and by this reference incorporated herein
as if fully set forth, and the parties further covenant and agree as follows:

1.       PURCHASE AND SALE.

         Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth below, the Company agrees to
sell to the Purchaser, and the Purchaser agrees to purchase from the Company at
the Exercise Price all of the Standby Shares, if any, which, as of the
Expiration Date, have not been subscribed for by Rightsholders through the
exercise of the Rights.

2.       DELIVERY AND PAYMENT.

         Upon receipt of notice from the Company as to the number of the Standby
Shares as of the Expiration Date, the Purchaser agrees to pay for the Standby
Shares on or before the fifth (5th) business day following the Expiration Date,
which date and time may be postponed by written agreement between the Purchaser

                                      -67-
