UNDERWRITERS' STATEMENT
COMPUTATIONAL MATERIALS

FIRST UNION COMMERCIAL MORTGAGE TRUST-
COMMERCIAL MORTGAGE PASS THROUGH CERTIFICATES
FUNB SERIES 1999-Cl

The attached tables and statistical analysis (the "Computational Materials") are
privileged and confidential and are intended for use by the addressee only.
These Computational Materials are furnished to you solely by First Union Capital
Markets (the "Underwriter") and not by the issuer of the certificates identified
above (the "Offered Certificates") or any other party. The issuer of the Offered
Certificates has not prepared or taken part in the preparation of these
materials. None of the Underwriters, the issuer of the Offered Certificates, or
any other party makes any representation as to the accuracy or completeness of
the information herein. The information herein is preliminary, and will be
superseded by the applicable prospectus supplement and by any other information
subsequently filed with the Securities and Exchange Commission. The information
herein may not be provided to any third party other than the addressee's legal,
tax, financial and/or accounting advisors for the purposes of evaluating such
information.

Numerous assumptions were used in preparing the Computational Materials which
may or may not be stated herein. As such, no assurance can be given as to the
accuracy, appropriateness or completeness of the Computational Materials in any
particular context; or as to whether the Computational Materials reflect future
performance. These Computational Materials should not be construed as either a
prediction or as legal, tax, financial or accounting advice.

Any yields or weighted average lives shown in the Computational Materials are
based on prepayment and other assumptions and actual experience may dramatically
affect such yields or weighted average lives. In addition, it is possible that
prepayments on the underlying assets will occur at rates slower or faster than
the rates assumed in the attached Computational Materials. Furthermore, unless
otherwise provided, the Computational Materials assume no losses on the
underlying assets and no interest shortfall. The specific characteristics of the
Offered Certificates may differ from those shown in the Computational Materials
due to difference between the actual underlying assets and the hypothetical
assets used in preparing the Computational Materials. The principal amount and
designation of any security described in the Computational Materials are subject
to change prior to issuance.

Although a registration statement (including the prospectus) relating to the
Offered Certificates has been filed with the Securities and Exchange Commission
and is effective, the final prospectus supplement relating to the Offered
Certificates has not been filed with the Securities and Exchange Commission.
This communication shall not constitute an offer to sell or the solicitation of
an offer to buy nor shall there be any sale of the Offered Certificates in any
state in which such offer, solicitation or sale would be unlawful prior to
registration or qualification under the securities laws of any such state.
Prospective purchasers are referred to the final prospectus and prospectus
supplement relating to the Offered Certificates for definitive terms of the
Offered Certificates and the collateral.

Please be advised that mortgage-backed and/or asset-backed securities may not be
appropriate for all investors. Potential investors must be willing to assume,
among other things, market price volatility, prepayments, yield curve and
interest rate risks. Investors should fully consider the risk of an investment
in these Offered Certificates.

If you have received this communication in error, please notify the sending
party immediately by telephone and return the original to such party by mail.

- --------------------------------------------------------------------------------
Investors should read the Underwriters' Statement which accompanies these
Computational Materials.

Prospective investors are advised to carefully read, and should rely soley on,
the final prospectus and prospectus supplement (the "Final Prospectus") relating
to the certificates referred to herein (the "Offered Certificates) in making
their investment decision. These Computational Materials have been based upon
the assumptions described above, which most likely will not represent the actual
experience of the Mortgage Pool in the future. No representation is made herein
as to the actual rate or timing of principal payments or prepayments on any of
the underlying Mortgage Loans in the Mortgage Pool or the actual performance
characteristics of the Offered Certificates. Prior to making any investment
decision, a prospective investor should receive and fully review the Final
Prospectus. NOTHING HEREIN SHOULD BE CONSIDERED AN OFFER TO SELL OR SOLICITATION
OF AN OFFER TO BUY ANY OFFERED CERTIFICATES.

UNDERWRITERS' STATEMENT
COMPUTATIONAL MATERIALS

FIRST UNION COMMERCIAL MORTGAGE TRUST-
COMMERCIAL MORTGAGE PASS THROUGH CERTIFICATES
FUNB SERIES 1999-Cl

The attached tables and statistical analysis (the "Computational Materials") are
privileged and confidential and are intended for use by the addressee only.
These Computational Materials are furnished to you solely by First Union Capital
Markets (the "Underwriter") and not by the issuer of the certificates identified
above (the "Offered Certificates") or any other party. The issuer of the Offered
Certificates has not prepared or taken part in the preparation of these
materials. None of the Underwriters, the issuer of the Offered Certificates, or
any other party makes any representation as to the accuracy or completeness of
the information herein. The information herein is preliminary, and will be
superseded by the applicable prospectus supplement and by any other information
subsequently filed with the Securities and Exchange Commission. The information
herein may not be provided to any third party other than the addressee's legal,
tax, financial and/or accounting advisors for the purposes of evaluating such
information.

Numerous assumptions were used in preparing the Computational Materials which
may or may not be stated herein. As such, no assurance can be given as to the
accuracy, appropriateness or completeness of the Computational Materials in any
particular context; or as to whether the Computational Materials reflect future
performance. These Computational Materials should not be construed as either a
prediction or as legal, tax, financial or accounting advice.

Any yields or weighted average lives shown in the Computational Materials are
based on prepayment and other assumptions and actual experience may dramatically
affect such yields or weighted average lives. In addition, it is possible that
prepayments on the underlying assets will occur at rates slower or faster than
the rates assumed in the attached Computational Materials. Furthermore, unless
otherwise provided, the Computational Materials assume no losses on the
underlying assets and no interest shortfall. The specific characteristics of the
Offered Certificates may differ from those shown in the Computational Materials
due to difference between the actual underlying assets and the hypothetical
assets used in preparing the Computational Materials. The principal amount and
designation of any security described in the Computational Materials are subject
to change prior to issuance.

Although a registration statement (including the prospectus) relating to the
Offered Certificates has been filed with the Securities and Exchange Commission
and is effective, the final prospectus supplement relating to the Offered
Certificates has not been filed with the Securities and Exchange Commission.
This communication shall not constitute an offer to sell or the solicitation of
an offer to buy nor shall there be any sale of the Offered Certificates in any
state in which such offer, solicitation or sale would be unlawful prior to
registration or qualification under the securities laws of any such state.
Prospective purchasers are referred to the final prospectus and prospectus
supplement relating to the Offered Certificates for definitive terms of the
Offered Certificates and the collateral.

Please be advised that mortgage-backed and/or asset-backed securities may not be
appropriate for all investors. Potential investors must be willing to assume,
among other things, market price volatility, prepayments, yield curve and
interest rate risks. Investors should fully consider the risk of an investment
in these Offered Certificates.

If you have received this communication in error, please notify the sending
party immediately by telephone and return the original to such party by mail.

Investors should read the Underwriters' Statement which accompanies these
Computational Materials.

Prospective investors are advised to carefully read, and should rely soley on,
the final prospectus and prospectus supplement (the "Final Prospectus") relating
to the certificates referred to herein (the "Offered Certificates) in making
their investment decision. These Computational Materials have been based upon
the assumptions described above, which most likely will not represent the actual
experience of the Mortgage Pool in the future. No representation is made herein
as to the actual rate or timing of principal payments or prepayments on any of
the underlying Mortgage Loans in the Mortgage Pool or the actual performance
characteristics of the Offered Certificates. Prior to making any investment
decision, a prospective investor should receive and fully review the Final
Prospectus. NOTHING HEREIN SHOULD BE CONSIDERED AN OFFER TO SELL OR SOLICITATION
OF AN OFFER TO BUY ANY OFFERED CERTIFICATES.

UNDERWRITERS' STATEMENT
COMPUTATIONAL MATERIALS

FIRST UNION COMMERCIAL MORTGAGE TRUST-
COMMERCIAL MORTGAGE PASS THROUGH CERTIFICATES
FUNB SERIES 1999-Cl

The attached tables and statistical analysis (the "Computational Materials") are
privileged and confidential and are intended for use by the addressee only.
These Computational Materials are furnished to you solely by First Union Capital
Markets (the "Underwriter") and not by the issuer of the certificates identified
above (the "Offered Certificates") or any other party. The issuer of the Offered
Certificates has not prepared or taken part in the preparation of these
materials. None of the Underwriters, the issuer of the Offered Certificates, or
any other party makes any representation as to the accuracy or completeness of
the information herein. The information herein is preliminary, and will be
superseded by the applicable prospectus supplement and by any other information
subsequently filed with the Securities and Exchange Commission. The information
herein may not be provided to any third party other than the addressee's legal,
tax, financial and/or accounting advisors for the purposes of evaluating such
information.

Numerous assumptions were used in preparing the Computational Materials which
may or may not be stated herein. As such, no assurance can be given as to the
accuracy, appropriateness or completeness of the Computational Materials in any
particular context; or as to whether the Computational Materials reflect future
performance. These Computational Materials should not be construed as either a
prediction or as legal, tax, financial or accounting advice.

Any yields or weighted average lives shown in the Computational Materials are
based on prepayment and other assumptions and actual experience may dramatically
affect such yields or weighted average lives. In addition, it is possible that
prepayments on the underlying assets will occur at rates slower or faster than
the rates assumed in the attached Computational Materials. Furthermore, unless
otherwise provided, the Computational Materials assume no losses on the
underlying assets and no interest shortfall. The specific characteristics of the
Offered Certificates may differ from those shown in the Computational Materials
due to difference between the actual underlying assets and the hypothetical
assets used in preparing the Computational Materials. The principal amount and
designation of any security described in the Computational Materials are subject
to change prior to issuance.

Although a registration statement (including the prospectus) relating to the
Offered Certificates has been filed with the Securities and Exchange Commission
and is effective, the final prospectus supplement relating to the Offered
Certificates has not been filed with the Securities and Exchange Commission.
This communication shall not constitute an offer to sell or the solicitation of
an offer to buy nor shall there be any sale of the Offered Certificates in any
state in which such offer, solicitation or sale would be unlawful prior to
registration or qualification under the securities laws of any such state.
Prospective purchasers are referred to the final prospectus and prospectus
supplement relating to the Offered Certificates for definitive terms of the
Offered Certificates and the collateral.

Please be advised that mortgage-backed and/or asset-backed securities may not be
appropriate for all investors. Potential investors must be willing to assume,
among other things, market price volatility, prepayments, yield curve and
interest rate risks. Investors should fully consider the risk of an investment
in these Offered Certificates.

If you have received this communication in error, please notify the sending
party immediately by telephone and return the original to such party by mail.

Investors should read the Underwriters' Statement which accompanies these
Computational Materials.

Prospective investors are advised to carefully read, and should rely solely on,
the final prospectus and prospectus supplement (the "Final Prospectus") relating
to the certificates referred to herein (the "Offered Certificates) in making
their investment decision. These Computational Materials have been based upon
the assumptions described above, which most likely will not represent the actual
experience of the Mortgage Pool in the future. No representation is made herein
as to the actual rate or timing of principal payments or prepayments on any of
the underlying Mortgage Loans in the Mortgage Pool or the actual performance
characteristics of the Offered Certificates. Prior to making any investment
decision, a prospective investor should receive and fully review the Final
Prospectus. NOTHING HEREIN SHOULD BE CONSIDERED AN OFFER TO SELL OR SOLICITATION
OF AN OFFER TO BUY ANY OFFERED CERTIFICATES.
