           STATEMENT REGARDING ASSUMPTIONS AS TO SECURITIES, PRICING
                        ESTIMATES, AND OTHER INFORMATION

The information contained in the attached materials (the "Information") may
include various forms of performance analysis, security characteristics and
securities pricing estimates for the securities addressed. Please read and
understand this entire statement before utilizing the Information. Should you
receive Information that refers to the "Statement Regarding Assumptions and
Other Information," please refer to this statement instead.

The Information is illustrative and is not intended to predict actual results
which may differ substantially from those reflected in the Information.
Performance analysis is based on certain assumptions with respect to significant
factors that may prove not to be as assumed. You should understand the
assumptions and evaluate whether they are appropriate for your purposes.
Performance results are based on mathematical models that use inputs to
calculate results. As with all models, results may vary significantly depending
upon the value of the inputs given. Inputs to these models include but are not
limited to: prepayment expectations (economic prepayment models, single expected
lifetime prepayments or a vector of periodic prepayments), interest rate
assumptions (parallel and nonparallel changes for different maturity
instruments), collateral assumptions (actual pool level data, aggregated pool
level data, reported factors or imputed factors), volatility assumptions
(historically observed or implied current) and reported information (paydown
factors, rate resets, and trustee statements). Models used in any analysis may
be proprietary making the results difficult for any third party to reproduce.
Contact your registered representative for detailed explanations of any modeling
techniques employed in the Information.

The Information addresses only certain aspects of the applicable security's
characteristics and thus does not provide a complete assessment. As such, the
Information may not reflect the impact of all structural characteristics of the
security, including call events and cash flow priorities at all prepayment
speeds and/or interest rates. You should consider whether the behavior of these
securities should be tested as assumptions different from those included in the
Information. The assumptions underlying the Information, including structure and
collateral, may be modified from time to time to reflect changed circumstances.
Any investment decision should be based only on the data in the prospectus and
the prospectus supplement or private placement memorandum (collectively, the
"Offering Documents") and the then current version of the Information. Offering
Documents contain data that is current as of their publication dates and after
publication may no longer be complete or current. The Information is provided
solely by the Underwriters not as agent for any issuer, and although it may be
based on data supplied to it by an issuer, the issuer has not participated in
its preparation and makes no representations regarding its accuracy or
completeness. Contact your registered representative for Offering Documents,
current Information or additional materials, including other models for
performance analysis, which are likely to produce different results, and any
further explanation regarding the Information.

Any pricing estimates the Underwriters have supplied at your request (a)
represent our view, at the time determined, of the investment value of the
securities between the estimated bid and offer levels, the spread between which
may be significant due to market volatility or illiquidity, (b) do not
constitute a bid by any person for any security, (c) may not constitute prices
at which the securities could have been purchased or sold in any market, (d)
have not been confirmed by actual trades, may vary from the value the
Underwriters assign any such security while in its inventory, and may not take
into account the size of a position you have in the security, and (e) may have
been derived from matrix pricing that uses data relating to other securities
whose prices are more readily ascertainable to produce a hypothetical price
based on the estimated yield spread relationship between the securities.

General Information: The data underlying the Information has been obtained from
sources that we believe are reliable, but we do not guarantee the accuracy of
the underlying data or computations based thereon. The Underwriters, and/or
individuals thereof may have positions in these securities while the Information
is circulating or during such period may engage in transactions with the issuer
or its affiliates. We act as principal in transactions with you, and
accordingly, you must determine the appropriateness for you of such transactions
and address any legal, tax, or accounting considerations applicable to you. The
Underwriters shall not be a fiduciary or advisor unless we have agreed in
writing to receive compensation specifically to act in such capacities. If you
are subject to ERISA, the Information is being furnished on the condition that
it will not form a primary basis for any investment decision. The Information is
not a solicitation of any transaction in securities which may be made only by
prospectus when required by law, in which event you may obtain such prospectus
from the Underwriters.

(1)  The Pass-Through Rates of the Class A-1 and Class A-2 Certificates shall be
     a fixed rate per annum or, if a lower rate, the weighted average of the Net
     Mortgage Rates of the Mortgage Loans (such Net Mortgage Rates determined
     without taking into account any reductions thereto resulting from
     modifications of the Mortgage Loans or otherwise following the Cut-Off
     Date) (the "NWAC Rate"). The pass-through rate of the Class B Certificates
     will be a per annum rate equal to the NWAC Rate for such Distribution Date

     Class F Certificates will be a per annum rate equal to the NWAC Rate for
     such Distribution Date. The Class X pass-through rate with respect to any

     average of the non-default interest rates specified in the notes relating
     to each mortgage loan in the trust fund, net of the related Administrative

                                 certificates in sequential order based on their
                                 alphabetical designations. In general, each
                                 class of certificates will receive an interest
                                 distribution on any distribution date only

                                 designation has received all amounts of
                                 interest distributable thereto on such date.

                                 distributions on a pro rata basis before any
                                 other class receives interest. In general, each
                                 class of certificates, other than the Class X
                                 Certificates, will receive a principal
                                 distribution on any distribution date only
                                 after each class with an earlier alphabetical
                                 designation has received all amounts

                                 earlier alphabetical designation has been
                                 reduced to zero. See "Description of the
                                 Certificates - Distributions" in the
                                 preliminary Prospectus Supplement.

                                 Servicing Agreement) of principal and interest
                                 on the mortgage loans will generally be
                                 allocated in reverse alphabetical order
                                 starting with Class M. Losses allocable to the
                                 Class A-1 and Class A-2 Certificates and,
                                 solely with respect to Realized Losses that
                                 reduce the amount of interest otherwise
                                 distributable, to the Class X Certificates,
                                 will be allocated pro rata. However, certain
                                 interest shortfalls as a result of the timing
                                 of prepayments and certain balloon payments
                                 will be allocated to each class of certificates
                                 pro rata based on their respective interest
                                 entitlements. See "Description of the
                                 Certificates - Subordination; Allocation of
                                 Losses, Shortfalls and Expenses" in the

CERTIFICATE STRUCTURE SUMMARY (CONTINUED)

SERVICER ADVANCING:                    The servicer will be required to make (i)
                                       P & I Advances (as described in the
                                       Pooling and Servicing Agreement) and (ii)
                                       Servicing Advances (defined as customary,
                                       reasonable and necessary "out-of-pocket"
                                       costs and expenses in connection with the
                                       servicing of a mortgage loan after a
                                       default (whether or not a payment
                                       default), delinquency or other
                                       unanticipated event, or in connection
                                       with the administration of a REO
                                       property). The servicer will be obligated
                                       to make such P&I Advances and Servicing
                                       Advances only to the extent that the
                                       servicer determines that the amount so
                                       advanced will be recoverable from
                                       subsequent payments or collections
                                       (including Insurance Proceeds,
                                       Liquidation Proceeds and REO Income) in
                                       respect of such mortgage loan or REO
                                       Property. See "Description of the
                                       Certificates - Advances" in the
                                       preliminary Prospectus Supplement. The
                                       servicer will not be required to advance
                                       Yield Maintenance Charges.

SPECIAL SERVICER RESPONSIBILITIES:     When a mortgage loan is more than 60 days
                                       delinquent, or upon the occurrence of
                                       certain other events, the servicer will
                                       transfer its servicing responsibilities
                                       to the special servicer. Subject to the
                                       Servicing Standards set forth in the
                                       Pooling and Servicing Agreement and
                                       subject to certain other limitations
                                       described therein, the special servicer
                                       may agree to certain loan extensions,
                                       amendments and modifications following a
                                       Servicing Transfer Event (as defined in
                                       the Pooling and Servicing Agreement). The
                                       special servicer also generally has the
                                       right to grant or withhold consent to
                                       material modifications, waivers,
                                       amendments and consents recommended by
                                       the servicer with respect to mortgage
                                       loans, other than a modification of a
                                       Money Term (as defined in the Pooling and
                                       Servicing Agreement). See "Servicing of
                                       the Mortgage Loans" in the preliminary
                                       Prospectus Supplement.

APPRAISAL REDUCTIONS:                  An appraisal will be obtained by the
                                       special servicer if a mortgage loan
                                       becomes 120 days delinquent, or upon the
                                       occurrence of certain other Appraisal
                                       Events (as defined in the Pooling and
                                       Servicing Agreement). An Appraisal
                                       Reduction (as defined in the Pooling and
                                       Servicing Agreement) would have the
                                       effect of reducing the amount of P & I
                                       Advances made by the servicer, trustee or
                                       the fiscal agent, as the case may be. See
                                       "Descriptions of the Certificates -
                                       Appraisal Reductions" in the preliminary

PREPAYMENT PROVISIONS

PREPAYMENT RESTRICTIONS:      As of the Cut-Off Date, 100% of the mortgage loans
                              have protection against voluntary prepayment.

                              o    33.6% are locked out until their respective
                                   maturity dates (or, with respect to the ARD
                                   Loans, Anticipated Repayment Date);

                              o    62.0% are locked out until generally one to
                                   six months before their respective maturity
                                   dates, after which time there are no
                                   restrictions on voluntary prepayments;

                              o    2.9% are locked out for three to five years,
                                   after which time, at the borrower's option,
                                   either (i) voluntary prepayment is allowed
                                   with the payment of a Yield Maintenance
                                   Charge or (ii) defeasance of the mortgage
                                   loan is permitted (as described below).
                                   Generally, these loans may be prepaid without
                                   restriction during a period which is between
                                   3 and 6 months prior to maturity;

                              o    1.5% are locked out for generally two to five
                                   years, after which time prepayment is allowed
                                   with the payment of a Yield Maintenance
                                   Charge

                              See "Description of the Mortgage Pool - Yield
                              Maintenance, Prepayment and Lockout Provisions" in
                              the preliminary Prospectus Supplement.

LOCKOUT/ DEFEASANCE:          The terms of 98.5% of the mortgage loans generally
                              permit the related borrower at any time,
                              commencing approximately three to five years after
                              the date of origination, but in no event before
                              the second anniversary of the issuance of the
                              certificates, to substitute non-callable U.S.
                              Treasury obligations for the mortgaged property
                              and to obtain the release of the related mortgage
                              on the mortgaged property. Such U.S. Treasury
                              obligations must provide for payments on or before
                              each due date and the Maturity/ARD Date in an
                              amount at least equal to the amounts payable on
                              each such date under the terms of the related
                              mortgaged loan. In the case of 163 of the mortgage
                              loans representing 95.6% of the Initial Pool
                              Balance, such collateral substitution is the only
                              method of obtaining a release of the mortgage on
                              the related mortgaged property and all voluntary
                              prepayments are prohibited during the loan term.

ALLOCATION OF YIELD           On any Distribution Date, Yield Maintenance
MAINTENANCE CHARGES:          Charges collected during the related Collection
                              Period will be distributed by the Paying Agent on
                              the classes of Offered Certificates as follows: to
                              each of the Class A, Class B, Class C, Class D,
                              Class E and Class F Certificates, for each such
                              Class an amount equal to the product of (a) a
                              fraction, the numerator of which is the amount
                              distributed as principal to such Class on such
                              Distribution Date, and the denominator of which is
                              the total amount distributed as principal to all
                              classes of Certificates on such Distribution Date,
                              (b) the Base Interest Fraction for the related
                              principal prepayment and such class of Offered
                              Certificates and (c) the aggregate amount of Yield
                              Maintenance Charges collected on such principal
                              prepayment during the related Collection Period.

PREPAYMENT PROVISIONS (CONTINUED)

ALLOCATION OF YIELD            The "Base Interest Fraction" with respect to any
MAINTENANCE                    principal prepayment on any mortgage loan  that
CHARGES: (CONTINUED)           provides for payment of a Yield Maintenance
                               Charge and with respect to each of the Class A-1,
                               Class A-2, Class B, Class C, Class D, Class E and
                               Class F Certificates is a fraction (A) whose
                               numerator is the greater of (x) zero and (y) the
                               difference between (i) the pass-through rate on
                               such class of Offered Certificates and (ii) the
                               Yield Rate used in calculating the Yield
                               Maintenance Charge with respect to such principal
                               prepayment and (B) whose denominator is the
                               difference between (i) the Mortgage Rate on the
                               related mortgage loan and (ii) the Yield Rate
                               used in calculating the Yield Maintenance Charge
                               with respect to such principal prepayment;
                               provided, however, that under no circumstances
                               shall the Base Interest Fraction be greater than
                               one. If such Yield Rate is greater than the
                               Mortgage Rate on the related mortgage loan, then
                               the Base Interest Fraction shall equal zero. Any
                               remaining Yield Maintenance Charges will be
                               distributed to the Class X Certificates.

PARTIAL RELEASE PROVISIONS:    6 of the mortgage loans representing 3.9% of the
                               Initial Pool Balance are cross-collateralized
                               with other mortgage loans and may be released
                               from such loan group by substitution of U.S.
                               Treasury securities (as previously described) in
                               amounts equal to not less than 110% and in some
                               cases 125% of the amounts payable on all
                               remaining due dates and the Maturity Date under
                               the terms of the related Mortgage Note subject to
                               certain DSCR and/or LTV tests.

                               4 mortgage loans representing 2.6% of the Initial
                               Pool Balance are secured by two or more mortgaged
                               properties and allow for the release of the
                               mortgage on one or more of the related mortgaged
                               properties through substitution of U.S. Treasury
                               securities generally in an amount equal to 125%
                               of the remaining monthly payments and balloon

borrower or (ii) any additional encumbrance of the property, in each case
without the prior written consent of the lender. The mortgage loan documents
permit transfers of interest in the borrower provided that certain conditions
are satisfied, including among other conditions, that certain principals
continue to own at least 50% of their original ownership interest in the
borrower, at least one of such principals continues to control the management of
the borrower and the lender receives confirmation from DCR and Fitch that the
transfer would not result in a downgrade, qualification or withdrawal of the
then current ratings assigned to any class of certificates.

THE PROPERTY

     The property is a 316-room Holiday Inn hotel consisting of eight wood frame
and stucco buildings. The property features a 6,498 square foot full service
restaurant in a free standing building, operating on a lease with Bakers Square.
In addition, the property has a meeting room and a pool/spa. The property is
located near the San Diego Convention Center, Sea World, the San Diego Sports
Arena, Balboa Park, the San Diego Zoo, and Old Town San Diego.

     The property was constructed in two phases (1982 and 1987). The borrower
purchased the property in phases between 1995 and 1997, and, during these two
years, performed an extensive property renovation. The renovation included the
conversion of 192 rooms into suites. This work included all new insulation,
bathroom fixtures, flooring, furniture, and case goods. The exterior was
restuccoed, repainted, and re-roofed.

     The property is divided into eight parcels, of which one approximately
0.60-acre parcel is encumbered by an unsubordinated ground lease expiring on
March 15, 2035. 42 of the property's 316 rooms are located on such parcel. The
fee owner includes, MTB, LLC, the borrower (50%), and Palmer Hughes,
unaffiliated to the borrower (50%), as tenants in common. The ground lessee
("Lease 1") is Midway Group, which pays current annual ground rent of $69,194.
Midway Group subleases the parcel to Sarika Group ("Lease 2"), an entity related
to the borrower, for current annual ground rent of $181,187. Sarkia Group
sub-subleases the parcel to MTB, LLC ("Lease 3") for a current annual ground
rent of $204,096, with a CPI-based increase every three years. Lease 1 provides
notice to the lender of default, but does not provide to the lender an
opportunity to cure any default thereunder; however, a 50% interest in the fee
estate of the 0.60-acre parcel is security for this loan. Additionally, Lease 2
and Lease 3 provide the lender with notice of default, an opportunity to cure
and the right to a new lease on the same terms.

THE BORROWER

     The borrower is 3 Theaters, Inc., is a wholly owned subsidiary of
Entertainment Properties Trust, a Maryland real estate investment trust. The
borrower is a single purpose entity whose organizational documents do not permit
it to engage in any business unrelated to the mortgaged properties, nor have any
assets other than the mortgaged properties or any indebtedness (subject to
certain limited exceptions such as trade payables incurred in the ordinary
course of business) other than the mortgage loan. Additionally, the borrower's
organizational documents require an independent director and the unanimous vote
of directors of the borrower in connection with the filing of a petition in
bankruptcy. The lender received an opinion from borrower's counsel that, among
other things, the assets of the borrower would not be consolidated with the
assets of any party considered having a principal interest in the borrower in
the event of a bankruptcy or insolvency of such party.

MANAGEMENT

     The properties are managed by the borrower.

ESCROWS

     If the borrower fails to provide to the lender satisfactory evidence of
payment of real estate taxes and property insurance premiums (and in the case of
the Boise Stadium 21 property, ground rents) in accordance with the loan
documents, the mortgage loan documents require the borrower to fund escrows for
such items. If the properties are not maintained in accordance with the loan
documents, the mortgage loan documents require the borrower to fund an
additional escrow for future capital expenditures.

ADDITIONAL DEBT/TRANSFERS

     The loan documents provide that the mortgage loan will become immediately
due and payable upon (i) any transfer of the borrower's interest in the property
or any transfer of more than 49% of the shares in the borrower or (ii) any
additional encumbrance of the property, in each case without the prior written
consent of the lender, except as described below.

     The borrower has the right to transfer simultaneously all three properties
subject to the mortgages upon the payment of a 1% assumption fee, confirmation
from DCR and Fitch that the transfer would not result in a downgrade,
qualification (if applicable) or withdrawal of the then current ratings assigned
to any class of certificates and satisfaction of other conditions specified in
the mortgage loan documents.

THE PROPERTY

     The Seattle Gift Center is a 182,419 square foot gift mart facility which
was constructed in 1976 as a two-story office building. After conversion to a
gift mart, it was expanded twice; three new stories were added in 1978 and a
five-story tower was added in 1983. There are approximately 120 showrooms in
which wholesale gift products are sold to Pacific Northwest retailers. The major
tenants at the center include Pacific Rim (8,375 square feet) under a lease
expiring November 2002 and Enesco Corp. (6,288 square feet) under a lease
expiring April 2000.

GROUND LEASE

     A portion of the Seattle Gift Center property is constructed on the
borrower's interest as a tenant under a ground lease. The ground lease expires
December 31, 2019. Notwithstanding the above, the ground lease is subject to the
borrower's option to purchase the ground lessor's fee interest which may be
exercised in 2004. The fee interest when purchased will become subject to a
first mortgage lien securing the mortgage loan. The borrower has escrowed
$715,000 with the lender, which, together with the accrued interest thereon, is
expected to be sufficient to purchase the fee at the negotiated price of
$850,000. The purchase option is required to be consummated immediately upon
exercise of the option. If the ground lessor is unable to comply with the terms
of the purchase option, the time period for exercising the option will be
extended for the duration of such inability.
