DATED July 22, 1999 (1) ALGO VISION PLC (2) BEESON GREGORY LIMITED (3) IAT AG ----------------------------- LOCK-IN AGREEMENT ----------------------------- THIS AGREEMENT is made on July 22, 1999 BETWEEN: (1) ALGO VISION PLC, a company registered in England and Wales with registered number 3794223 whose registered office is at 2 Serjeants' Inn, London EC4Y 1LT ("COMPANY"); (2) BEESON GREGORY LIMITED, a company registered in England and Wales with registered number 2316630 whose registered office is at The Registry, Royal Mint Court, London EC3N 4EY ("BEESON GREGORY"); and (3) IAT AG, company incorporated in Switzerland with its registered office at CH-5300, Turgi, Switzerland ("IAT"). RECITALS A. The Company is a public limited liability company incorporated in England and Wales with an authorised share capital of (pound)200,000 divided into 20,000,000 shares of 1 pence each ("Shares") of which 7,000,000 Shares have been issued and are fully paid or credited as fully paid. B. The Company intends to apply for the admission ("ADMISSION") to trading on the European Association of Securities Dealers Automated Quotation System ("EASDAQ") of 14,464,654 Shares constituting the whole of its issued ordinary share capital and the shares forming part of its authorised but unissued share capital sufficient to satisfy obligations to issue further shares which it has assumed at Admission. 1 C. Beeson Gregory has been appointed as Sponsor in relation to the application for Admission in accordance with the EASDAQ Rules. D. Rule 3550 of the EASDAQ Admission Rules (as amended) provides that, as an issuer coming to EASDAQ for the first time, the Company is also required to undertake that each shareholder with more than 10 per cent. of its issued share capital at Admission will not dispose of more than 20 per cent. of its holding for a reasonable period of time from the first day of trading of the Shares ("TRADING COMMENCEMENT"), except through a public offering. D. Beeson Gregory, as Sponsor of the Company, believes, and IAT acknowledges, that because of the size of its shareholding in the Company, and having regard to the EASDAQ Admission Rules (as amended), it is in the best interests of the Company and of protecting the market in the Shares that such a significant shareholder of the Company at Admission refrain from selling or procuring the sale of Shares for a period following Admission. E. Pursuant to a share exchange and subscription agreement between IAT and the Company dated 22 July 1999, the Company agreed to allot to IAT 500,000 Shares in exchange for all of the shares or other equity interests held by IAT in Algo Vision Schweiz AG and Algo Vision Systems GmbH ("ADMISSION SHARES"). F. Pursuant to a subscription agreement between IAT and the Company dated 22 July 1999, it was agreed that IAT would subscribe for and be allotted 250,000 Shares within 30 days of Admission, in consideration of a cash payment of US$ 2.5 million ("SUBSEQUENT SUBSCRIPTION SHARES"), and the parties to this agreement have agreed that the provisions of this agreement shall apply to 200,000 of such Subsequent Subscription Shares. 2 NOW IT IS HEREBY AGREED as follows: 1.
