                       REPORT OF INDEPENDENT ACCOUNTANTS


The Board of Directors and Shareholders of
Serv-Tech, Inc.

We have audited the consolidated statements of operations, changes in
stockholders' equity and cash flows of Serv-Tech, Inc. for the year ended
December 31, 1994. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.

We conducted our audit 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 audit provides a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated results of operations and the cash
flows of Serv-Tech, Inc. for the year ended December 31, 1994, in conformity
with generally accepted accounting principles.
