REPORT OF MANAGEMENT

     The Company's management is responsible for the preparation and
presentation of the consolidated financial statements. The consolidated
financial statements have been prepared in conformity with accounting principles
generally accepted in the United States of America and as such include amounts
based on judgements and estimates made by management.

     The Company's system of internal accounting controls is designed to provide
reasonable assurance at reasonable cost that assets are safeguarded from loss or
unauthorized use, and that the financial records may be relied upon for the
preparation of the consolidated financial statements.

     The consolidated financial statements have been audited by our independent
auditors, Deloitte and Touche LLP. Their audit is conducted in accordance with
auditing standards generally accepted in the United States of America and
provides an independent assessment as to the fair presentation, in all material
respects, of the Company's consolidated financial statements.

     The Audit Committee of the Board of Directors meets periodically with
management and the independent auditors to review internal accounting controls
and the quality of financial reporting. Financial management and the independent
auditors have full and free access to the Audit Committee.

INDEPENDENT AUDITORS' REPORT

The Board of Directors
Eagle-Picher Holdings, Inc.:

     We have audited the accompanying consolidated balance sheets of
Eagle-Picher Holdings, Inc. and subsidiaries as of November 30, 2001 and 2000,
and the related consolidated statements of income (loss), shareholders' equity
(deficit), and cash flows for each of the three years in the period ended
November 30, 2001. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.


     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Eagle-Picher
Holdings, Inc. as of November 30, 2001 and 2000, and the results of its
operations and its cash flows for each of the three years in the period ended
November 30, 2001, in conformity with accounting principles generally accepted
in the United States of America.
