ITEM 1.  CHANGES IN CONTROL OF REGISTRANT

         Not applicable.

ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         Not applicable.

ITEM 3.  BANKRUPTCY OR RECEIVERSHIP.

         Not applicable.

ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

         On April 19, 1999, the Board of Directors, upon the recommendation of
the Audit Committee, appointed Ernst & Young LLP as independent auditors to
conduct the Company's Annual Audit for the fiscal year ending December 31, 1999,
subject to stockholder approval. If a majority of the shares voting at the
Annual Meeting does not approve of the appointment, the Board of Directors will
reconsider that appointment. It is believed that representatives of Ernst &
Young LLP will be present at the Annual Meeting, will have an opportunity to
make a statement if they desire, and will be available to respond to appropriate
questions from stockholders.

         The 1997 and 1998 Annual Audits were conducted by Deloitte & Touche
LLP. On April 19, 1999, however, Deloitte & Touche LLP was dismissed as the
Company's independent auditors for the 1999 Annual Audit, and the dismissal was
approved by the Audit Committee. The reports of Deloitte & Touche LLP for the
past two fiscal years did not contain any adverse opinion or any disclaimer of
opinion and were not qualified or modified as to uncertainty, audit scope, or
accounting principles. Furthermore, in connection with the audits of the
Company's financial statements for the two fiscal years ended December 31, 1997
and December 31, 1998 and during the interim period through April 19, 1999,
there were no disagreements with Deloitte & Touche LLP on any matter of
accounting principles or practices, financial statement disclosures, or auditing
scope or procedure. The Company did not at any time during the foregoing period
prior to Ernst & Young's engagement consult with that firm regarding the
application of any accounting principles to any specified transaction, the type
of audit opinion that might be rendered, or with respect to any matter that was
either the subject of a disagreement with the Company's prior auditors or that
would constitute a reportable event within the scope of Item 304(a) of SEC
Regulation S-K.

         Attached to this Report as Exhibit 16 is a letter dated April 27, 1999
from Deloitte & Touche LLP, addressed to the Commission, setting forth their
agreement with the first four sentences of the second paragraph and the first
sentence of the third paragraph of this Item. 4.

ITEM 5.  OTHER EVENTS.

         In April 1999, the Company's Board of Directors amended Section 3.2 of
the Company's Bylaws to reduce the number of directors to nine (9). Such
amendment is reflected in the revised Bylaws filed as Exhibit 3.2(a) to this
Form 8-K.

Item 6.  Resignations of Registrant's Directors.

         Not applicable.

ITEM 7.  FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS.

         Not applicable.

ITEM 8.  CHANGE IN FISCAL YEAR.

         Not applicable.

ITEM 9.  SALES OF EQUITY SECURITIES PURSUANT TO REGULATION S.

         Not applicable.
