<PAGE>



          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 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
     provided for in this section shall be for the account of the
     Unitholders of record at the conclusion of the primary of-
     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-
     tial 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 in-
     cluding 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.
