Termination: If a Trust Wind-Up Event occurs, any Securities held by the Trust will be liquidated (by delivery to the Security Issuer in the event of a redemption or pursuant to the terms of the Swap Agreement in the event of an exercise of the Swap Agreement). If the related 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 as to amounts treated as accrued interest on the Units, (ii) amounts received as principal or par on the Securities will be applied to the Unit Principal Balance of the Units up to 100% of the Unit Principal Balance of each Unit, and (iii) if prior to July 11, 2007, any amount received as a make-whole premium or redemption premium on the Securities will be applied to the Units up to $2.50 per Unit. Remaining accrued interest will be applied to the Expense Administrator's fee. Any remaining amounts will be paid to the Swap Counterparty as a Swap Termination Payment under the Swap Agreement. If the Trust is terminated for any other reason, the proceeds of liquidation will be applied to redeem the Units. If the proceeds of liquidation exceed the aggregate Unit Principal Balance and accrued interest on the Securities, the excess will be paid to the Swap Counterparty as a Swap Termination Payment under the Swap Agreement. Self-Tenders by Security 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 contrary from the Unitholders. Terms of Retained Interest: The Depositor retains the right to receive any and 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 $835,069. 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.

The Selling Agent must solicit at least three of such bids from registered broker-dealers of national reputation, but additional bids may be solicited from one or more financial institutions or other counterparties with credit worthiness acceptable to the Selling Agent in its discretion. 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 cash settlement applies and 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 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 and, if in excess of such amount, in a $25 integral multiple in excess thereof. The principal amount of Securities deposited must be in the same ratio to the Unit Principal Balance 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 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. Any accrued interest will be reflected in the price of the additional Units and the Securities. The Rating Agency Condition must be satisfied in connection with any such additional issuance.
