                             the Securities will not be sold, the Swap

                             held by the Trust will be liquidated (by delivery
                             to the Security Issuer in the event of a
                             redemption).

                             If a Trust Wind-Up Event occurs due to a redemption
                             of the Securities by the Security Issuer or
                             exercise of the call rights under the Swap
                             Agreement as to all Securities held by the Trust,
                             (i) amounts received as accrued interest on the
                             Securities will be applied to the Class A Units and
                             the Class B Units pro rata in proportion to the
                             amount of accrued interest outstanding on each such
                             Class, (ii) amounts received as principal or par on
                             the Securities will be applied to the Unit
                             Principal Balance of the Class A Units up to 100%
                             of the Unit Principal Balance of each Class A Unit,
                             (iii) if prior to March 19, 2007, any amount
                             received as a make-whole premium or redemption
                             premium on the Securities will be applied to the
                             Class A Units up to $2.50 per Class A Unit.
                             Remaining accrued interest will be applied to the
                             Expense Administrator's fee. Any remaining amounts
                             (other than the Class B Unit Payment Obligation of
                             the Swap Counterparty) will be paid to the Swap
                             Counterparty as a Swap Termination Payment under
                             the Swap Agreement. Amounts in respect of the Class
                             B Unit Payment Obligation of the Swap Counterparty
                             (as described in Schedule III) shall be paid to the
                             Class B Units.

                             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 8.125% (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
                             Agreement.

Issuer:                      The Trust will not participate in any self-tender
                             by the Security Issuer for the Securities and the
                             Trustee will not accept any instructions to the

                             all interest that accrues on the Securities prior
                             to the Closing Date. The Depositor will receive
                             such accrued interest on the first Distribution
                             Date for the 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 $220,846.

                             If a Security Default occurs on or 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.

Call Option Terms:           Not applicable.

Security Default:            The definition of Security Default in the Standard
                             Terms shall not apply. A "Security Default" shall
                             mean one of the following events: (i) the
                             acceleration of the outstanding Securities under

                             Security Agreement and failure to pay the
                             accelerated amount on the acceleration date; (ii)
                             the failure of the Security Issuer (or the Security
                             Guarantor on its behalf or under the Security
                             Guaranty) to pay an installment of principal of, or
                             any amount of interest due on, the Securities after
                             the due date thereof and after the expiration of
                             any applicable grace period; or (iii) the
                             occurrence of any of the events of default under
                             such Securities and/or Security Agreement relating
                             to the insolvency or bankruptcy of the Security
                             Issuer or the Security Guarantor.

Sale of Securities:          If the Trust must sell the Securities it holds, the
                             Trust will sell the Securities through the Selling
                             Agent in accordance with Section 9.03(b) and the
                             following terms. The Selling Agent will solicit
                             bids for all of the Securities held by the Trust
                             from at least three registered broker-dealers of
                             national reputation. The Selling Agent will, on
                             behalf of the Trust, sell the Securities at the
                             highest bid price received. The Selling Agent may
                             not bid for the Securities.

                             If the Swap Counterparty exercises any of its
                             Options other than in connection with a redemption
                             of the Securities by the Security Issuer, a number
                             of Securities corresponding to the number of
                             Options exercised by the Swap Counterparty will be
                             sold by the Selling Agent on behalf of the Trust.

                             If the Selling Agent cannot obtain a bid for the
                             Securities in excess of 100% of the aggregate Unit
                             Principal Balance of the Class A Units to be
                             redeemed and accrued interest on the Securities to
                             be sold, then the Securities will not be sold, the
                             Swap Counterparty's exercise will be rescinded (and
                             the Swap Counterparty shall be entitled to exercise
                             such Option(s) in the future) and any related Trust
                             Wind-Up Event will be deemed not to have occurred.

Additional Issuance
of Units:                    Upon no less than 5 days' notice to the Trustee,
                             the Depositor may deposit additional Securities at
                             any time in exchange for additional Units in a
                             minimum aggregate amount of $250,000 (with respect
                             to the Class A Units issued ) and, if in excess of
                             such amount, in a $25 integral multiple in excess
                             thereof (with respect to the Class A Units issued).
                             The principal amount of Securities deposited must
                             be in the same ratio to the Unit Principal Balance
                             (and Notional Amount with respect to the Class B
                             Units) of the Units received for such deposit as
                             the ratio of the aggregate principal amount of the
                             Securities deposited on the Closing Date to the
                             aggregate Unit Principal Balance (and aggregate
                             Notional Amount with respect to the Class B Units)
                             on the Closing Date. The Depositor must either
                             arrange for the Swap Counterparty and the Trust to
                             increase proportionally the notional amount under
                             the Swap Agreement or arrange for an additional
                             Swap Agreement to be entered into between the Trust
                             and an additional Swap Counterparty. The Depositor
                             must also arrange the issuance of Class B Units
                             with a Notional Amount equal to the Unit Principal
                             Balance being issued in connection with an
                             additional issuance. Any accrued interest will be
                             reflected in the price of the Securities and Class
                             A Units. The Rating Agency Condition must be
                             satisfied in connection with any such additional
                             issuance.

                             telephone) during the Exercise Period but no later

                             that is provided by the Third Party.

                             Administrator Payment Obligation"):

                             redemption in connection with the exercise of
                             Options hereunder and if any such exercise is an
                             exercise of less than all Options remaining
                             unexercised hereunder, Party A shall pay to the

                             Agreement), assuming for this purpose that the

                             Distribution Date, multiplied by the Option
                             Entitlement multiplied by the number of Options
                             exercised and divided by $54,550,000.

                             To Party B for Payment on the Class B Units (the

                             Upon any exercise hereunder or upon any redemption
                             of Bonds held by Party B by the Bond Issuer, Party
                             A shall pay to Party B, for payment to the
                             registered holder of the Class B Units, the present

                             the sum of (i) the amount of outstanding accrued
                             interest in respect of the Class B Unit
                             Corresponding Portion and (ii) the present value of
                             the remaining scheduled payments (other than any
                             accrued interest) in respect of the Class B Unit
                             Corresponding Portion discounted at a rate of
                             8.125% per annum on the basis of a 360 day year
                             consisting of twelve 30 day months.

Settlement Date:             As applicable, the Business Day of settlement of
                             the sale of the Bonds by Party B or the Business
                             Day of settlement of a redemption of Bonds by the
                             Bond Issuer.


         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 March 19, 2002,
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
amount), excluding accrued interest, in excess of the Strike Price (expressed as
a dollar amount).

         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.

         8. Account Details.
