     of the expenses reimbursable to the Depositor provided be-
     low, be borne by the Unit Holders, provided, however, that,
     to the extent all of such costs are not borne by Unit Hold-
     ers, the amount of such costs not borne by Unit Holders
     shall be borne by the Depositor and, provided further, how-
     ever, 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 the Trust
     subsequent to the deposit referred to in Section 2.01.  Upon
     notification from the Depositor that the primary offering
     period is concluded, the Trustee shall withdraw from the Ac-
     count or Accounts specified in the Prospectus or, if no Ac-
     count is therein specified, from the Principal Account, and
     pay to the Depositor the Depositor's 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 directed by the De-
     positor, 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 distribu-
     tion, sufficient for such reimbursement.  The reimbursement

     fering period and shall not be reflected in the computation
     of the Unit Value prior thereto.  As used herein, the De-
     positor's reimbursable expenses of organizing the Trust and
     sale of the Trust Units shall include the cost of the ini-
     tial preparation and typesetting of the registration state-
     ment, prospectuses (including preliminary prospectuses), the
     indenture, and other documents relating to the Trust, SEC
     and state blue sky registration fees, the cost of the ini-

     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.

     subsidiaries,   more  than  $2  billion  in  total   assets,   except  that

     issued  by the  Trustee  may not  exceed  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

<PAGE>

     receipt,  the  principal  thereof and interest  thereon (to the extent
     such interest is not used to pay Trust  expenses) to be  distributed on the

     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.

          G.  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 3.12 hereof,  as set forth in the
     prospectus for a Trust.  Definitions following this definition (9) shall be

          H. 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 a Trust,  the Trustee  shall pay the  account  created
     pursuant to Section 3.12 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.

<PAGE>

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

          J.  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.

          K. Section 3.12 shall be added as follows:

          Section 3.12.  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 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

<PAGE>

     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.

          L.  Reference  to "Dean  Witter  Select  Equity  Trust" is replaced by
     "Morgan Stanley Dean Witter Select Equity Trust".
