            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

We have examined management's assertion, included in the accompanying Report of
Management on Compliance, that The Bank of New York (the "Company") complied
with the PPLUS Minimum Servicing Standards (attached) as of and for the year
ended December 31, 2004 as it relates to PreferredPLUS Trust Series LMG-2.
Management is responsible for The Bank of New York's compliance with those
requirements. Our responsibility is to express an opinion on management's
assertion about The Bank of New York's compliance based on our examination.

Our examination was conducted in accordance with attestation standards
established by the American Institute of Certified Public Accountants and,
accordingly, included examining, on a test basis, evidence about the Company's
compliance with those requirements and performing such other procedures as we
considered necessary in the circumstances. We believe that our examination
provides a reasonable basis for our opinion. Our examination does not provide a
legal determination on the Company's compliance with specified requirements.

In our opinion, management's assertion that The Bank of New York complied with
the aforementioned requirements as of and for the year ended December 31, 2004
is fairly stated, in all material respects.
