                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Shareholders of
COHR Inc. and subsidiaries
Los Angeles, California:
 
     We have audited the accompanying consolidated balance sheets of COHR Inc.
and subsidiaries (the "Company") as of March 31, 1997 and 1996, and the related
consolidated statements of income, shareholders' equity, and cash flows for each
of the three years in the period ended March 31, 1997. Our audits also included
the financial statement schedule and exhibit listed in the Index. These
consolidated financial statements and financial statement schedules are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements and financial statement
schedule and exhibit based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. 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, such consolidated financial statements and financial
statement schedule and exhibit referred to above present fairly, in all material
respects, the consolidated financial position of the Company as of March 31,
1997 and 1996, and the consolidated results of its operations and its cash flows
for each of the three years in the period ended March 31, 1997 in conformity
with generally accepted accounting principles.
 
     As described in Note 15, the accompanying consolidated financial statements
as of March 31, 1997 and for the year then ended have been restated.
