ITEM 5. OTHER EVENTS.

     On January 7, 2002, Image Sensing Systems, Inc., a Minnesota corporation
(the "Company"), purchased all of the shares, par value HK$1.00 per share (each,
a "Share"), then held by the minority shareholders of the Company's subsidiary
Flow Traffic Limited ("Flow Traffic"), a company incorporated in the Hong Kong
Special Administrative Region of the People's Republic of China. The purchase
was made in accordance with the Shares Sale and Purchase Agreement dated
November 28, 2001, as amended on December 31, 2001 (the "Agreement"), among the
Company and the minority shareholders of Flow Traffic. Prior to this purchase,
the Company owned six Shares of Flow Traffic, and the minority shareholders
collectively owned four Shares of Flow Traffic.

     The Company agreed to pay the following amounts to the minority
shareholders as consideration for their Shares:

     o    Cash payments at the time of purchase totaling US$250,000.

     o    Additional payments totaling $450,000, payable at any time between
          April 1, 2003 and April 30, 2003 upon the request of the minority
          shareholders, which payments are secured by letters of credit drawn in
          favor of the minority shareholders and expiring on April 30, 2003.

     o    Non-interest bearing notes, maturing on January 7, 2007, in the
          aggregate principal amount of US$250,000, and convertible into an
          aggregate of 100,000 shares of Company common stock, par value $.01
          per share. The holders may demand payment for their notes at any time
          after April 1, 2003. The notes may be prepaid by the Company at any
          time during calendar year 2002 for their aggregate principal amount of
          $250,000 and without penalty or additional fees, or may be prepaid by
          the Company at any time after April 1, 2003, for the aggregate
          principal amount of $250,000 plus additional payments totaling
          $50,000. If not converted or paid by January 7, 2007, each note will
          be redeemed by the Company on that date for its principal amount. Each
          note also provides that if the note is converted into shares of
          Company common stock, the Company will register such shares with the
          U.S. Securities and Exchange Commission, if so requested by the
          holder.

     In addition to the foregoing consideration, if Flow Traffic achieves an
audited net profit before tax of HK$1,418,000 (approximately US$181,795) or
greater for fiscal year 2002, the Company will make an additional cash payment
totaling US$100,000 to the minority shareholders, payable within 10 days after
completion of Flow Traffic's annual audit.
