                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders
MEMC Electronic Materials, Inc.


     Under date of March 1, 2002, we reported on the consolidated balance sheets
of MEMC Electronic Materials, Inc. and subsidiaries as of December 31, 2001 and
2000, and the related consolidated statements of operations, stockholders'
equity (deficiency) and cash flows for the periods from January 1, 2001 through
November 13, 2001 and from November 14, 2001 through December 31, 2001 and for
each of the years in the two-year period ended December 31, 2000, as contained
in the 2001 annual report to stockholders. These consolidated financial
statements and our report thereon are incorporated by reference in the annual
report on Form 10-K/A (Amendment No. 2) for the year 2001. In connection with
our audits of the aforementioned consolidated financial statements, we also
audited the related financial statement schedule as listed in item 14(a)(2) of
this Form 10-K. This financial statement schedule is the responsibility of the
Company's management. Our responsibility is to express an opinion on this
financial statement schedule based on our audits.


     In our opinion, such financial statement schedule, when considered in
relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.

     As discussed in Note 2 to the Consolidated Financial Statements, MEMC's
former majority shareholder divested of its interest in MEMC to an unaffiliated
investor group. The transaction has been accounted for as a purchase, and the
investor group's basis in MEMC has been pushed-down to the MEMC accounting
records creating a new basis of accounting, effective November 13, 2001. As a
result of the acquisition, the consolidated financial information for the period
after the acquisition is presented on a different cost basis than that for the
periods before the acquisition and, therefore, is not comparable.
