ITEM 4. CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT
---------------------------------------------
On December 2, 1997, the Board of Directors voted to change independent
public accountants, dismissing Ernst & Young LLP as the independent accountants
for ChemTrak, Inc. (the "Company") and engaging Coopers & Lybrand LLP. Notice
of dismissal was delivered to Ernst & Young on December 4, 1997.
During the Company's two most recent fiscal years and the subsequent
interim period preceding the dismissal of Ernst & Young, (i) there were no
disagreements with Ernst & Young on any matter of accounting principles or
practices, financial statement disclosure, or auditing scope or procedures,
which if not resolved to its satisfaction would have caused it to make reference
in connection with its reports, and (ii) Ernst & Young has not advised the
Company of any reportable events as defined in paragraph (A) through (D) of
Regulation S-K Item 304(a)(1)(v).
During the Company's two most recent fiscal years and the subsequent
interim period prior to engaging Coopers & Lybrand, the Company has not
consulted Coopers & Lybrand with respect to any of the matters described in
Regulation S-K Item 304(a)(2)(i) or (ii).
