                           For information with respect to the underlying
                           securities held by PreferredPLUS Trust Series BLC-1,
                           please refer to periodic reports of Belo Corp.
                           (Commission file number 001-08598), including annual

                           and current reports on Form 8-K, and other
                           information on file with the Securities and Exchange
                           Commission (the "SEC"). You can read and copy these
                           reports and other information at the public reference
                           facilities maintained by the SEC at Room 1580, 100 F
                           Street, NE, Washington, D.C. 20549. You may obtain
                           copies of this material for a fee by writing to the
                           SEC's Public Reference Section of the SEC at 100 F
                           Street, NE, Washington, D.C. 20549. You may obtain
                           information about the operation of the Public
                           Reference Room by calling the SEC at 1-800-SEC-0330.
                           You can also access some of this information
                           electronically by means of the SEC's website on the
                           Internet at http://www.sec.gov, which contains
                           reports, proxy and information statements and other
                           information that the underlying securities issuer has
                           filed electronically with the SEC.

                           Although we have no reason to believe the information
                           concerning the underlying securities or the
                           underlying securities issuer contained in the
                           underlying securities issuer's Exchange Act reports
                           is not reliable, neither the depositor nor the
                           trustee participated in the preparation of such
                           documents, or made any due diligence inquiry with
                           respect to the information provided therein. No
                           investigation with respect to the underlying
                           securities issuer (including, without limitation, no
                           investigation as to its financial condition or
                           creditworthiness) or of the underlying securities has
                           been made. You should obtain and evaluate the same
                           information concerning the underlying securities
                           issuer as you would obtain and evaluate if your
                           investment were directly in the underlying securities
                           or in other securities issued by the underlying
                           securities issuer. There can be no assurance that
                           events affecting the underlying securities or the
                           underlying securities issuer have not occurred or
                           have not yet been publicly disclosed which would
                           affect the accuracy or completeness of the publicly
                           available documents described above.

         ITEM 1A.          RISK FACTORS

                           Your investment in the trust certificates will
                           involve certain risks. You should carefully consider
                           the following discussion of risks, and the other
                           information included or incorporated by reference in
                           the applicable prospectus supplement and the
                           accompanying prospectus. You should also carefully
                           consider any risk factors and other information that
                           the underlying securities issuer may file in its
                           Exchange Act reports as referenced in Item 1 above.

                           IF THE UNDERLYING SECURITIES ARE REDEEMED PRIOR TO
                           THEIR MATURITY DATE OR IF ANY CALL WARRANT HOLDER
                           EXERCISES ITS OPTIONAL CALL RIGHT, YOU MAY NOT BE
                           ABLE TO REINVEST YOUR REDEMPTION OR CALL PROCEEDS AT
                           A YIELD COMPARABLE TO THE YIELD YOU WOULD HAVE
                           RECEIVED ON YOUR TRUST CERTIFICATES

                           The yield you will realize on your trust certificates
                           depends upon several factors, including:

                           o        the purchase price of the trust
                                    certificates,

                           o        when you acquire your trust certificates,

                           o        whether the underlying securities issuer
                                    exercises its option to redeem the
                                    underlying securities, and

                           o        whether the call warrant holders exercise
                                    their optional rights to purchase
                                    outstanding trust certificates.

                           The underlying securities issuer will have the right,
                           if certain conditions are met, to redeem the
                           underlying securities. Because the underlying
                           securities issuer has the right to redeem the
                           underlying securities early, we cannot assure you
                           that the trust will be able to hold the underlying
                           securities until their maturity date.

                           Although the call warrant holders are not obligated
                           to exercise the call warrants, the yield you will
                           realize on your trust certificates also depends on
                           whether the call warrant holders exercise their call
                           warrants to purchase the trust certificates.

                           Prevailing interest rates at the time of an early
                           redemption or a call exercise may be lower than the
                           yield on your trust certificates. Therefore, you may
                           be unable to realize a comparable yield upon
                           reinvesting the funds you receive from an early
                           redemption or the exercise of any call warrants. In
                           addition, if the prevailing market value of the trust
                           certificates exceeds the redemption price or call
                           exercise price paid to you upon a redemption of the
                           underlying securities or the exercise of a call, you
                           will not be able to realize such excess.

                           YOU MAY NOT BE PAID IF THE ASSETS OF THE TRUST ARE
                           INSUFFICIENT

                           Currently, the trust has no significant assets other
                           than the underlying securities. If the underlying
                           securities are insufficient to make payments or
                           distributions on the trust certificates, no other
                           assets will be available for payment of the
                           deficiency.

                           THE TRUSTEE WILL NOT MANAGE THE UNDERLYING SECURITIES

                           Except as described below, the trust will not dispose
                           of any underlying securities, even if an event occurs
                           that adversely affects the value of the underlying
                           securities or that adversely affects the underlying
                           securities issuer. As provided in the applicable
                           trust agreement, the trust will dispose of the
                           underlying securities only if:

                           o        there is a payment default on any underlying
                                    securities,

                           o        there is another type of default that
                                    accelerates the maturity of the underlying
                                    securities, or

                           o        the underlying securities issuer ceases to
                                    file Exchange Act reports.

                           Under the first circumstance listed above, the
                           trustee must sell the underlying securities on behalf
                           of the trust, even if adverse market conditions
                           exist. The trustee has no discretion to do otherwise.
                           If adverse market conditions do exist at the time of
                           the trustee's sale of the underlying securities, you
                           may incur greater losses than if the trust continued
                           to hold the underlying securities.

                           THE TRUST CERTIFICATES ARE SUBJECT TO THE
                           CREDITWORTHINESS OF THE UNDERLYING SECURITIES ISSUER

                           The trust certificates represent interests in
                           obligations of the underlying securities issuer. In
                           particular, the trust certificates will be subject to
                           all the risks associated with directly investing in
                           the underlying securities issuer's unsecured
                           subordinated debt obligations. Neither the underlying
                           indenture nor the underlying securities place a
                           limitation on the amount of indebtedness that may be
                           incurred by the underlying securities issuer.

                           THE PAYMENTS OWED TO THE TRUST CERTIFICATEHOLDERS ARE
                           UNSECURED OBLIGATIONS

                           In a liquidation, holders of the underlying
                           securities, including the trust, will be paid only
                           after holders of secured obligations of the
                           underlying securities issuer. According to the
                           underlying securities prospectus, the underlying
                           securities are general unsecured obligations of the
                           underlying securities issuer, which rank on a parity
                           with all other unsecured senior indebtedness of the
                           underlying securities issuer. However, if the
                           underlying securities issuer subjects any of its
                           property to a lien then the underlying securities,
                           and any other obligations which are then outstanding
                           and subject to a similar covenant, will be secured
                           ratably with the indebtedness or obligation secured
                           by that lien and for the same length of time, subject
                           to certain exceptions.

                           THE RATINGS OF THE TRUST CERTIFICATES MAY CHANGE

                           At the time of issuance, Moody's and/or S&P assigned
                           ratings to the trust certificates equivalent to the
                           ratings of the underlying securities as of the date
                           of the applicable prospectus supplement.

                           Any rating issued with respect to the trust
                           certificates is not a recommendation to purchase,
                           sell or hold a security. Ratings do not comment on
                           the market price of the trust certificates or their
                           suitability for a particular investor. We cannot
                           assure you that these ratings will remain for any
                           given period of time or that a ratings agency would
                           not revise or withdraw entirely the ratings if, in
                           its judgment, circumstances (including, without
