<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On March&nbsp;11, 2003, we appointed KBA Group LLP to serve as our independent public accountants, replacing our former independent public accountants
Ernst&nbsp;&amp; Young LLP, effective immediately, subject to ratification by our stockholders at our 2003 annual meeting. The decision to change independent auditors was approved by our Board of
Directors upon the recommendation and approval of our Audit Committee. </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ernst&nbsp;&amp;
Young LLP's reports on our consolidated financial statements for the past two years did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or
modified as to uncertainty, audit scope or accounting principles. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During
our two most recent fiscal years and through the date of this Current Report on Form&nbsp;8-K, there were no disagreements with Ernst&nbsp;&amp; Young LLP on any
matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to Ernst&nbsp;&amp; Young LLP's satisfaction, would have caused them
to make reference to the subject matter in connection with their reports on our consolidated financial statements and supporting schedules for such years; and there were no reportable events, as
listed in Item 304(a)(1)(v)&nbsp;of Regulation&nbsp;S-K. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
provided Ernst&nbsp;&amp; Young LLP with a copy of the foregoing disclosures. Attached as Exhibit&nbsp;16.1 is a copy of Ernst&nbsp;&amp; Young LLP's letter, dated March&nbsp;11,
2003, stating their agreement with such statements. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During
our two most recent fiscal years and through the date of this Current Report on Form&nbsp;8-K, we did not consult KBA Group LLP with respect to the application of
accounting principles to a specified transaction, either completed or proposed, or the type of the audit opinion that might be rendered on our consolidated financial statements, or any other matters
or reportable events listed in Items 304(a)(2)(i)&nbsp;and (ii)&nbsp;of Regulation&nbsp;S-K. </FONT></P>
