CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT. On January 8, 2003, Image Sensing Systems, Inc. ("ISS") engaged Grant Thornton LLP as its new independent accountants, commencing with the audit for the fiscal year ended December 31, 2002, and thereby dismissed Ernst & Young LLP. The decision to change independent accountants was approved by the Board of Directors of ISS. The reports of Ernst & Young LLP on ISS's financial statements for the past two years ended December 31, 2001 and December 31, 2000 contained no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle. In connection with the audits for the fiscal years ended December 31, 2001 and December 31, 2000 and all interim periods preceding the dismissal, there have been no disagreements with Ernst & Young LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Ernst & Young LLP, would have caused them to make reference thereto in their report on the financial statements for such years. During the fiscal years ended December 31, 2001 and December 31, 2000 and all subsequent interim periods and to January 8, 2003, the date of dismissal, there have been no reportable events (as defined in Regulation S-K Item 304(a)(1)(v)). ISS delivered a copy of this Form 8-K report to Ernst & Young LLP on January 8, 2003, and requested that Ernst & Young LLP furnish it with a letter addressed to the Securities and Exchange Commission (the "SEC") stating whether or not Ernst & Young LLP agrees with the above statements. Attached hereto as Exhibit 16 is a copy of the letter of Ernst & Young LLP to the SEC dated January 8, 2003. During the fiscal years ended December 31, 2001 and December 31, 2000 and to January 8, 2003, ISS has not consulted with Grant Thornton LLP on any items concerning the application of accounting principles to a specified transaction, the type of audit opinion that might be rendered on ISS's financial statements, or the subject matter of a disagreement or reportable event with the former auditor (as described in Regulation S-K Item 304(a)(2)).
