"Shortfall") by one of the following methods:

******(1)	Pay the Shortfall in cash by check or wire transfer, or

(2)	Issue to Seller up to 500,000 additional shares of N-Vision Technology
common stock such that the value of the original Deposit plus the value of
the additional shares totals $625,000.

If Buyer elects Options (2) above and the total value of the original Deposit plus the additional
500,000 shares is still less than $625,000 Buyer shall pay the balance of the guaranteed amount to
Seller in cash so that the total of the original Deposit plus the additional 500,000 shares plus the cash
payment is $625,000.  The additional shares to be issued under this Guarantee shall be calculated
by subtracting from $625,000 the product of 500,000 shares multiplied by the Average Share Price
to determine the Shortfall.  The Shortfall divided by the Average Share Price will then determine the
number of additional shares to be issued as part of the Guarantee.  The Average Share Price will be
calculated on May 25, 2002 by taking the average of the share prices for the previous twenty (20)
trading days.

1.9	***Default.*****  If this Agreement is terminated, other than by reason of a breach of this Agreement
by Buyer, Buyer and the Seller shall deliver to Agent a written notice instructing (AGENT) to return
the Authorization Letter to Buyer.  If Seller believes that Buyer has breached this Agreement, Seller
shall provide to Buyer written notice setting forth the particulars of the alleged breach.  If Buyer is
unable to remedy the alleged breach, and Seller elects to terminate this Agreement as the result
thereof, Buyer and Seller shall deliver to Agent a joint notice instructing Agent to remit the
Authorization Letter to Buyer's Transfer Agent so that the Deposit may be paid to Seller, provided,
however, that if Buyer disputes the alleged breach, Seller and Buyer shall submit such dispute to
arbitration by a panel of three arbitrators.  If such a dispute is submitted to arbitration, Buyer and
Seller, or either of them, shall provide to Agent written notice of such fact that identifies the nature
of the dispute and the arbitrators selected and that instructs Agent to handle the Authorization Letter
in accordance with instructions to be delivered to Agent by the arbitrators following the issuance of
the arbitrators decision.  Any such notice delivered unilaterally by Buyer or Seller shall also be
delivered to the other party, and proof of the delivery of such notice shall be provided to Agent.  If
this Agreement is terminated, other than by reason of a breach of this Agreement by Buyer, Buyer
and Seller shall deliver to Agent a written notice instructing Agent to return to Buyer the
Authorization Letter. Failure of Buyer to close this transaction due to a material breach by Seller of
any of the Representations and Warranties of Seller as listed in Article 2.1 of this Agreement shall
not constitute a breach of the Agreements by Buyer.
