# INDEPENDENT
AUDITORS REPORT ON AGREEMENTS WITH STATE STREET BANK AND TRUST COMPANY

Board of Directors Washington Mutual Bank, FA

We have audited, in accordance with
auditing standards generally accepted in the United States of America, the consolidated
statement of financial condition of Washington Mutual Bank, FA and subsidiaries (including
Washington Mutual Mortgage Securities Corp. (WMMSC)) as of December 31, 2001, and the
related consolidated statements of income, of stockholders equity and comprehensive
income, and of cash flows for the year then ended, and have issued our report thereon
dated February 19, 2002 (March 1, 2002, as to Note 2) (which report expresses an
unqualified opinion and includes an explanatory paragraph relating to the adoption of
Statement of Financial Accounting Standards No. 133, Accounting for Derivative
Instruments and Hedging Activities, as amended, on January 1, 2001).

In connection with our audit, nothing
came to our attention that caused us to believe that WMMSC failed to comply with the
terms, covenants, provisions, or conditions of the sections of the agreements between
WMMSC and State Street Bank and Trust Company (State Street Bank), as listed for each
series of certificates described in the accompanying schedule (Schedule I), insofar as
they relate to financial and accounting matters. However, our audit was not directed
primarily toward obtaining knowledge of noncompliance.

In connection with our audit, nothing
came to our attention that caused us to believe that WMMSC failed to comply with the
terms, covenants, provisions, or conditions of the sections of the agreement between Pamex
Mortgage Trust 1999-A (Issuer), WMMSC (Master Servicer), Pamex Funding, Inc. (Depositor),
and State Street Bank (Indenture Trustee), as listed for the certificate described in the
accompanying schedule (Schedule II), insofar as they relate to financial and accounting
matters. However, our audit was not directed primarily toward obtaining knowledge of
noncompliance.

This report is intended solely for
the information and use of the Board of Directors, management of Washington Mutual Bank,
FA, and State Street Bank, and is not intended to be and should not be used by anyone
other than these specified parties. However, this report may become a matter of public
record as a result of being included as an exhibit to certain Forms 10-K filed with the
Securities and Exchange Commission on behalf of the trusts that are established in
