language:

              Section 3.01. INITIAL COST The costs of organizing the Trust and
       sale of the Trust Units shall, to the extent of the expenses reimbursable
       to the Depositor provided below, be borne by the Unit Holders, PROVIDED,
       HOWEVER, that, to the extent all of such costs are not borne by Unit
       Holders, the amount of such costs not borne by Unit Holders shall be
       borne by the Depositor and, PROVIDED FURTHER, HOWEVER, that the liability
       on the part of the Depositor under this section shall not include any
       fees or other expenses incurred in connection with the administration of

       reimbursable expenses of organizing the Trust and sale of the Trust Units
       in an amount certified to the Trustee by the Depositor. If the balance of
       the Principal Account is insufficient to make such withdrawal, the
       Trustee shall, as di-

<PAGE>

                                      -3-

       rected by the Depositor, sell Securities identified by the Depositor, or
       distribute to the Depositor Securities having a value, as determined
       under Section 4.01 as of the date of distribution, sufficient for such
       reimbursement. The reimbursement provided for in this section shall be
       for the account of the Unitholders of record at the conclusion of the
       primary offering period and shall not be reflected in the computation of
       the Unit Value prior thereto. As used herein, the Depositor's
       reimbursable expenses of organizing the Trust and sale of the Trust Units
       shall include the cost of the initial preparation and typesetting of the

       prospectuses), the indenture, and other documents relating to the Trust,
       SEC and state blue sky registration fees, the cost of the initial
       valuation of the portfolio and audit of the Trust, the initial fees and
       expenses of the Trustee, and legal and other out-of-pocket expenses
       related thereto, but not including the expenses incurred in the printing
       of preliminary prospectuses and prospectuses, expenses incurred in the
       preparation and printing of brochures and other advertising materials and
       any other selling expenses. Any cash which the Depositor has identified
       as to be used for reimbursement of expenses pursuant to this Section
       shall be reserved by the Trustee for such purpose and shall not be
       subject to distribution or, unless the Depositor otherwise directs, used
       for payment of redemptions in excess of the per-Unit amount allocable to
       Units tendered for redemption.

              E. The third paragraph of Section 3.05 is hereby amended to add
       the following sentence after the first sentence thereof: "Depositor may
       direct the Trustee to invest the proceeds of any sale of Securities not
       required for the redemption of Units in eligible money market instruments
       selected by the Depositor which will include only negotiable certificates
       of deposit or time deposits of domestic banks which are members of the
       Federal Deposit Insurance Corporation and which have, together with their
       branches or subsidiaries, more than $2 billion in total assets, except
       that certificates of deposit or time deposits of smaller domestic banks
       may be held provided the deposit does not exceed the insurance coverage
       on the instrument (which currently is $100,000), and provided further
       that the Trust's aggregate holding of certificates of deposit or time
       deposits issued by the Trustee may not ex-

                                      -4-


       ceed the insurance coverage of such obligations and U.S. Treasury notes
       or bills (which shall be held until the maturity thereof) each of which
       matures prior to the earlier of the next following Distribution Date or
       90 days after receipt, the principal thereof and interest thereon (to the
       extent such interest is not used to pay Trust expenses) to be distributed
       on the earlier of the 90th day after receipt or the next following
       Distribution Date."

              F. The first sentence of each of Sections 3.10, 3.11 and 3.12 is
       amended to insert the following language at the beginning of such
       sentence, "Except as otherwise provided in Section 3.13,".

              G. The following new Section 3.13 is added

              Section 3.13. EXTRAORDINARY EVENT-SECURITY RETENTION AND VOTING.
       In the event the Trustee is notified of any action to be taken or
       proposed to be taken by holders of the securities held by the Trust in
       connection with any proposed merger, reorganization, spin-off, split-off
       or split-up by the issuer of stock or securities held in the Trust, the
       Trustee shall take such action or refrain from taking any action, as
       appropriate, so as to insure that the securities are voted as closely as
       possible in the same manner and in the same general proportion as are the
       securities held by owners other than the Trust. If stock or securities
       are received by the Trustee, with or without cash, as a result of any
       merger, reorganization, spin-off, split-off or split-up by the issuer of
       stock or securities held in the Trust, the Trustee at the direction of
       the Depositor may retain such stock or securities in the Trust. Neither
       the Depositor nor the Trustee shall be liable to any person for any
       action or failure to take action with respect to this section.

              H. Section 1.01 is amended to add the following definition: (9)
       "Deferred Sales Charge" shall mean any deferred sales charge payable in
       accordance with the provisions of Section 3.14 hereof, as set forth in
       the prospectus for a Trust. Definitions following this definition (9)
       shall be renumbered.

              I. Section 3.05 is hereby amended to add the following paragraph
       after the end thereof: On each Deferred Sales Charge payment date set
       forth in the prospectus for

<PAGE>

                                      -5-


       a Trust, the Trustee shall pay the account created pursuant to Section
       3.14 the amount of the Deferred Sales Charge payable on each such date as
       stated in the prospectus for a Trust. Such amount shall be withdrawn from
       the Principal Account from the amounts therein designated for such
       purpose.

              J. Section 3.06B(3) shall be amended by adding the following: "and
       any Deferred Sales Charge paid".

              K. Section 3.08 shall be amended by adding the following at the
       end thereof: "In order to pay the Deferred Sales Charge, the Trustee
       shall sell or liquidate an amount of Securities at such time and from
       time to time and in such manner as the Depositor shall direct such that
       the proceeds of such sale or liquidation shall equal the amount required
       to be paid to the Depositor pursuant to the Deferred Sales Charge program
       as set forth in the prospectus for a Trust.

              L. Section 3.14 shall be added as follows:

              Section 3.14. Deferred Sales Charge. If the prospectus for a Trust
       specifies a Deferred Sales Charge, the Trustee shall, on the dates
       specified in and as permitted by the prospectus, withdraw from the Income
       Account if such account is designated in the prospectus as the source of
       the payments of the Deferred Sales Charge, or to the extent funds are not
       available in that account or if such account is not so designated, from
       the Principal Account, an amount per Unit specified in the prospectus and
       credit such amount to a special, non-Trust account maintained at the
       Trustee out of which the Deferred Sales Charge will be distributed to the
       Depositor. If the Income Account is not designated as the source of the
       Deferred Sales Charge payment or if the balances in the Income and
       Principal Accounts are insufficient to make any such withdrawal, the
       Trustee shall, as directed by the Depositor, either advance funds, if so
       agreed to by the Trustee, in an amount equal to the proposed withdrawal
       and be entitled to reimbursement of such advance upon the deposit of
       additional monies in the Income Account or the Principal Account, sell
       Securities and credit the proceeds thereof to such special Depositor's
       account or credit Securities in kind to such special Depositor's Account.
       Such directions shall identify the Securities, if any, to be
<PAGE>

                                      -6-

       sold or distributed in kind and shall contain, if the Trustee is directed
       by the Depositor to sell a Security, instructions as to execution of such
       sales. If a Unit Holder redeems Units prior to full payment of the
       Deferred Sales Charge, the Trustee shall, if so provided in the
       prospectus, on the Redemption Date, withhold from the Redemption Price
       payment to such Unit Holder an amount equal to the unpaid portion of the
       Deferred Sales Charge and distribute such amount to such special
       Depositor's account or, if the Depositor shall purchase such Unit
       pursuant to the terms of Section 5.02 hereof, the Depositor shall pay the
       Redemption Price for such Unit less the unpaid portion of the Deferred
       Sales Charge. The Depositor may at any time instruct the Trustee to
       distribute to the Depositor cash or Securities previously credited to the
       special Depositor's account.

              M. The Distribution Agency Agreement is amended to be applicable
       to the Morgan Stanley Dean Witter Select Equity Trust, The Competitive
       Edge Best Ideas Portfolio series.

              N. Reference to "Dean Witter Select Equity Trust" is replaced by
