It is expected that during June 2004, a single series of certificates, expected
to be entitled, Citigroup Commercial Mortgage Trust 2004-C1, Commercial Mortgage
Pass-Through Certificates, Series 2004-C1 (the "Certificates"), will be issued
pursuant to a pooling and servicing agreement (the "Pooling and Servicing

Securities Inc. (the "Registrant"), a master servicer, a special servicer, a
trustee and a fiscal agent. It is expected that certain classes of the

Registrant's registration statement on Form S-3 (no. 333-108125) and sold to
Citigroup Global Markets Inc. ("CGMI"), Wachovia Capital Markets LLC ("WCM"),

and together with CGMI, WCM and CDC, the "Underwriters") pursuant to an
underwriting agreement (the "Underwriting Agreement") to be entered into by and
between the Registrant and the Underwriters.

         In connection with the expected sale of the Underwritten Certificates,
CGMI has advised the Registrant that it has furnished to prospective investors
certain information attached hereto as Exhibit 99.1 that may be considered
"Computational Materials" (as defined in the no-action letter dated May 20, 1994
issued by the Division of Corporation Finance of the Securities and Exchange
Commission (the "Commission") to Kidder, Peabody Acceptance Corporation I,
Kidder, Peabody & Co. Incorporated, and Kidder Structured Asset Corporation and
the no-action letter dated May 27, 1994 issued by the Division of Corporation
Finance of the Commission to the Public Securities Association) and "ABS Term

Association).

         The Computational Materials and ABS Term Sheets attached hereto have

Computational Materials and ABS Term Sheets is preliminary and will be
superseded by the final Prospectus Supplement relating to the Underwritten
Certificates and by any other information subsequently filed with the
