Changes in Registrant's Certifying Accountant. Mantyla McReynolds, Certified Public Accountants, of Salt Lake City, Utah, audited our financial statements for the years ended December 31, 2002 and 2001, and reviewed our financial statements for the quarterly periods ended March 31, 2002, June 30, 2002, September 30, 2002, and March 31, 2003, and June 30, 2003; these financial statements respectively accompanied our 10- KSB Annual Report for the year ended December 31, 2002, and our 10-QSB Quarterly Reports for the quarters ended March 31, 2002, June 30, 2002, September 30, 2002, and March 31, 2003, and June 30, 2003, which have previously been filed with the Securities and Exchange Commission. Following the completion of an Agreement and Plan of Reorganization (the "Agreement") between the Company, formerly known as Piezo Instruments, Inc., and Omni Medical of Nevada, Inc., a Nevada corporation ("Omni Nevada"), which was completed on or about September 5, 2003, the Company's new directors agreed that it would be in the best interest of the Company to retain the services of the certified public accountants who had been auditing the books and records of Omni Nevada prior to the completion of the Agreement. On November 10, 2003, the Board of Directors of the Company approved and accepted Gelfond, Hochstadt Pangburn, P.C. as the audit firm for the Company for the newly adopted fiscal year ending March 31, 2004. During the most recent fiscal year, and through November 10, 2003, there were no disagreements between us and Mantyla McReynolds, whether resolved or not resolved, on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which, if not resolved, would have caused them to make reference to the subject matter of the disagreement in connection with their reports. The reports of Mantyla McReynolds did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles except that certain issues raised substantial doubt about its ability to continue as a going concern. During the Company's two most recent fiscal years, and through November 10, 2003, Mantyla McReynolds has not advised us that any of the following exists or is applicable: (1) That the internal controls necessary for the Company to develop reliable financial statements do not exist, or that information has come to their attention that has led them to no longer be able to rely on our management's representations or that has made them unwilling to be associated with the financial statements prepared by management; (2) That our Company needs to expand significantly the scope of our audit, or that information has come to their attention that if further investigated may materially impact the fairness or reliability of a previously issued audit report or the underlying financial statements or any other financial presentation, or cause them to be unwilling to rely on management's representations or be associated with our financial statements for the foregoing reasons or any other reason; or (3) That they have advised us that information has come to their attention that they have concluded materially impacts the fairness or reliability of either a previously issued audit report or the underlying financial statements for the foregoing reasons or any other reason. During the Company's two most recent fiscal years, and through November 10, 2003, we have not consulted Gelfond Hochstadt Pangburn P.C. regarding the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on our financial statements or any other financial presentation whatsoever. We have provided Mantyla McReynolds with a copy of the disclosure provided under this Item of this Current Report and have advised them to provide us with a letter addressed to the Securities and Exchange Commission as to whether they agree or disagree with the disclosures made herein. A copy of their response is attached hereto and incorporated herein by this reference. See Item 7 of this Current Report. Item 7.
