liquidation of the Securities pursuant to Section 9.03 of the Trust Agreement.

Beneficial owners of the Units will receive distributions through the facilities of
The Depository Trust Company ("DTC") and the intermediaries through which they hold
their Units. DTC will present its Units to the Trustee in accordance with the
procedures specified by DTC and the Trustee. Beneficial owners of Units should
inquire with the intermediary holding their Units as to procedures for presentation
and final payment and should provide instructions in writing with respect to the
final distribution to their intermediary.

It is expected that the final distribution on the Units will be made within 30 days.
