Changes in Registrant's Certifying Accountant Previous Independent Accountants On February 27, 2003, Pivotal Self-Service Technologies Inc. dismissed PKF, Certified Public Accountants, a Professional Corporation ("PKF") as its principal accountants. Such action had been previously approved by the Registrant's Board of Directors. PKF's reports on the financial statements of the company for the past two years did not contain an adverse opinion or disclaimer of opinion, and were not modified as to audit scope or accounting principles. PKF's reports dated April 9, 2002 and April 5, 2001 each contained a paragraph expressing substantial doubt about the Registrant's ability to continue as a going concern. From the time of PKF's appointment as the company's auditors on April 2, 2001, through the date of this report, there has been no disagreements with PKF 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 PKF, would have caused it to make reference to the subject matter of the disagreements in connection with its reports. During the two most recent fiscal years and through the date of this report there have been no reportable events. New Independent Accountants On February 27, 2003, the Registrant retained Mintz & Partners LLP of Toronto, Ontario, Canada, as the company's independent accountants to conduct an audit of the Registrant's financial statements for the fiscal year ended December 31, 2002. This action was previously approved by the Registrant's Board of Directors. Item 7. Financial Statements and Exhibits (c) Exhibits 23.1 Letter from PKF re: resignation as certifying accountant.
