                                            Agreement are partially exercised or
                                            if there is a partial redemption of
                                            the Securities, the Trustee will

                                            in full from the proceeds of such

                                            Agreement or partial redemption of
                                            the Securities.

                                            If the Trust is terminated for any
                                            other reason, the proceeds of
                                            liquidation will be applied to
                                            redeem the Class A Units and the
                                            Class B Units. The Class A Units
                                            will have a claim on the proceeds of
                                            the liquidation equal to their
                                            aggregate Unit Principal Balance
                                            plus accrued interest. The Class B
                                            Units will have a claim on the
                                            proceeds of liquidation equal to the
                                            value calculated (x) by discounting
                                            each remaining scheduled payment at
                                            a rate of 7.95% (on the basis of a
                                            360 day consisting of twelve 30 day
                                            months) and adding (y) accrued
                                            interest. If the proceeds of the
                                            liquidation is less than the
                                            combined claim amounts of the Class
                                            A Units and the Class B Units, the
                                            proceeds will be distributed in
                                            proportion to the claim amounts of
                                            the Class A Units and the Class B
                                            Units in full satisfaction of the
                                            claims of the Units. If the proceeds
                                            of liquidation exceed the claims of
                                            the Class A Units and the Class B
                                            Units, the excess will be paid to
                                            the Swap Counterparty as a Swap
                                            Termination Payment under the Swap

                                            Trustee will not accept any
                                            instructions to the contrary from
                                            the Unitholders.

                                            Units and such amount shall be paid
                                            from the interest payment made with
                                            respect to the Securities on the
                                            first Distribution Date.

                                            The amount of the Retained Interest
                                            is $1,731,176.

                                            prior to the first Distribution Date
                                            and the Depositor does not receive
                                            such Retained Interest amount in
                                            connection with such Distribution
                                            Date, the Depositor will have a
                                            claim for such Retained Interest,
                                            and will share pro rata with holders
                                            of the Units to the extent of such
                                            claim in the proceeds from the
                                            recovery on the Securities.

                                            in the Standard Terms shall not
                                            apply. A "Security Default" shall

                                            outstanding Securities under the

                                            default under such Securities and/or
                                            Security Agreement relating to the
                                            insolvency or bankruptcy of the
                                            Security Issuer or the Security

                                            Securities it holds, the Trust will
                                            sell the Securities through the
                                            Selling Agent in accordance with

                                            terms. The Selling Agent must
                                            solicit at least three bids for all

                                            Agent may not bid for the
                                            Securities.

         3.  Additional Definitions.
             ----------------------

         "Class B Unit" means the Class B Unit issued under the Trust Agreement.

         "Class B Unit Corresponding Portion" means the portion of the Class B
Unit to be redeemed or corresponding notional amount reduction under the Trust
Agreement in connection with an exercise hereunder or a redemption by the Bond
Issuer.

         "Class B Unit Interest" means at any time and from time to time, the
interest on the Class B Unit Corresponding Portion that would have accrued at
the rate and in the manner specified in the Trust Agreement and would have been
payable at the times specified in the Trust Agreement had (i) the rights to
purchase the Bonds hereunder not been exercised and (ii) had no redemption by
the Bond Issuer occurred. For the avoidance of doubt, Class B Unit Interest
shall not include amounts actually paid on the Class B Units in connection with
the exercise of the right to purchase the Bonds hereunder or a redemption by the
Bond Issuer and the Class B Unit Interest shall not be construed to entitle the
Class B Unit to any "double" payment of interest.

         "Trust Agreement" means the trust agreement dated as of the date
hereof, between the MSDW Structured Asset Corp. and LaSalle Bank National
Association.

         4. Representations.  Morgan Stanley & Co. Incorporated is acting
as agent for both parties but does not guarantee the performance of Party A.

         5. Additional Termination Event.  As set forth in the Agreement,
a Trust Wind-Up Event will result in an Additional Termination Event under the
Agreement with respect to which Party B shall be the Affected Party and this
Transaction shall be an Affected Transaction.

         6. Swap Termination Payments. In the event an Early Termination Date is
designated with respect to which this Transaction is an Affected Transaction,
there shall be payable to Party A as a termination payment in lieu of the
termination payment determined in accordance with Section 6(e) of the Agreement
an amount equal to the excess (if any) of the sale proceeds (or redemption
proceeds), excluding accrued interest, of the Bonds in excess of the Strike
Price.

         7. Assignment. The rights under this Confirmation and the Agreement may
be assigned at any time and from time to time in whole or in part; provided that
the Rating Agency Condition (as defined in the Trust Agreement) is satisfied
with respect to such assignment and any transfer. The transferee in any such
assignment or transfer must be a qualified institutional buyer as defined in
Rule 144A under the Securities Act of 1933.
