I, Jimmy Whang, certify that:

         1.       I have reviewed this annual report on Form 10-K in respect
                  of the STRATS(SM) Trust For Wal-Mart Stores, Inc.
                  Securities, Series 2005-4 (the "Trust") and all reports on

         2.       Based on my knowledge, the information in these reports,
                  taken as a whole, does not contain any untrue statement of a
                  material fact or omit to state a material fact necessary to
                  make the statements made, in light of the circumstances
                  under which such statements were made, not misleading as of
                  the last day of the period covered by this annual report;

         3.       Based on my knowledge, the distribution or servicing
                  information required to be provided to the Depositor by the
                  Trustee under the trust agreement, for inclusion in these

                  based upon my knowledge and the annual compliance review
                  required under that agreement, and except as disclosed in
                  the reports, the Depositor and Trustee have each fulfilled
                  its obligations under that agreement; and

         5.       The reports disclose all significant deficiencies relating
                  to the compliance by the Trustee and the Depositor with the
                  minimum servicing or similar standards based upon the report
                  provided by an independent public accountant, after
                  conducting a review in compliance with the Uniform Single
