ORGANIZATION AND PURPOSE

Merrill Lynch Preferred Capital Trust VI (the "Trust") is a statutory business
trust formed on December 7, 1998 under the laws of the State of Delaware for the
exclusive purposes of (i) issuing the Trust Originated Preferred Securities (the
"Trust Preferred Securities") and the Trust Common Securities (together with the
Trust Preferred Securities, the "Trust Securities") representing undivided
beneficial ownership interests in the assets of the Trust, (ii) purchasing
Partnership Preferred Securities (the "Partnership Preferred Securities")
representing the limited partnership interests of Merrill Lynch Preferred
Funding VI, L.P. (the "Partnership") with the proceeds from the sale of the
Trust Securities, and (iii) engaging in only those other activities necessary or
incidental thereto. The Trust has a perpetual existence, subject to certain
termination events as provided in the Declaration of Trust under which it was
formed. The Trust intends to issue and sell its Trust Preferred Securities in a
public offering and to issue and sell its Trust Common Securities to Merrill
Lynch & Co., Inc. (the "Company"). No Trust Securities have been issued as of
June 25, 1999.

The Partnership Preferred Securities will be redeemable for cash, at the option
of the Partnership, in whole or in part, from time to time, after a certain date
to be determined. Upon any redemption of the Partnership Preferred Securities,
the Trust Preferred Securities will be redeemed, in whole or in part, as
applicable. Holders of the Trust Preferred Securities will have limited voting
rights and will not be entitled to vote to appoint, remove, or replace, or to
increase or decrease the number of, Trustees, which voting rights are vested
exclusively in the holder of the Trust Common Securities.

The Company will be obligated to pay compensation to the underwriters of the
offering of the Trust Preferred Securities. The Company will also pay all fees
and expenses related to the organization and operations of the Trust (including
any taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed by the United States or any other domestic
taxing authority upon the Trust) and be responsible for all debts and other
obligations of the Trust (other than the Trust Securities). The Company has
agreed to indemnify the trustees and certain other persons.
