CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT On October 7, 2004 CAS Medical Systems, Inc. (the "Registrant") dismissed PricewaterhouseCoopers LLP as the Registrant's Independent Registered Public Accounting Firm and selected and engaged UHY LLP as the Registrant's Independent Registered Public Accounting Firm for the fiscal year ending December 31, 2004. UHY LLP advised the Registrant of its acceptance of the engagement as of October 7, 2004. PricewaterhouseCoopers LLP's reports on the Registrant's financial statements for the fiscal years ended December 31, 2002 and 2003 did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the Registrant's two fiscal years ended December 31, 2002 and 2003 and the interim period from January 1, 2004 through October 7, 2004, there were no disagreements with PricewaterhouseCoopers LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements if not resolved to PricewaterhouseCoopers LLP's satisfaction, would have caused PricewaterhouseCoopers LLP to make reference thereto in its reports on the financial statements for such years. During the Registrant's two fiscal years ended December 31, 2002 and 2003 and the interim period from January 1, 2004 through October 7, 2004, there were no reportable events (as described in Regulation S-B Item 304 (a)(1)(iv)). The Registrant has provided PricewaterhouseCoopers LLP with a copy of the above statements and requested that PricewaterhouseCoopers LLP furnish it with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the above statements and, if not, stating the respects in which it does not agree. A copy of such letter is filed as Exhibit 16.1 to this Current Report on Form 8-K. During the two most recent fiscal years and through October 7, 2004, neither the Registrant nor anyone on its behalf has consulted with UHY LLP regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on the Registrant's financial statements, and neither a written report was provided to the Registrant nor oral advice was provided by UHY LLP that was an important factor considered by the Registrant in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of a disagreement, as described in Item 304 (a)(1)(iv) of Regulation S-B and the related instructions to Item 304 of Regulation S-B, or a reportable event, as described in Item 304 (a)(1)(iv) of Regulation S-B and the related instructions to Item 304 of Regulation S-B.
