Item 4. Changes In Registrant's Certifying Accountant
- -------
At a meeting held on August 22, 1996, the Board of Directors of the Company
approved the engagement of Ernst & Young LLP as its independent auditors for the
fiscal year ending December 31, 1996 to replace the firm of Grant Thornton LLP,
which was dismissed as auditors of the Company effective August 22, 1996. The
audit committee of the Board of Directors voted to recommend the change in
auditors to the Board of Directors on August 19, 1996.
The reports of Grant Thornton LLP on the Company's financial statements for
the past two fiscal years did not contain an adverse opinion or a disclaimer of
opinion and were not qualified or modified as to uncertainty, audit scope, or
accounting principles.
In connection with the audits of the Company's financial statements for each
of the two fiscal years ended December 31, 1995, and in the subsequent interim
period, there were no disagreements with Grant Thornton LLP on any matters of
accounting principles or practices, financial statement disclosure, or auditing
scope or procedure which, if not resolved to the satisfaction of Grant Thornton
LLP, would have caused Grant Thornton LLP to make reference to the matter in its
report.
The Company has requested Grant Thornton LLP to furnish it a letter
addressed to the Commission stating whether it agrees with the above statements.
A copy of that letter, dated August 29, 1996, is filed as Exhibit 16 to this
Form 8-K\A.
