2.   The Auction.
     ------------

2.1  Purpose; Incorporation by Reference of Auction
     Procedures and Settlement Procedures.
     -------------------------------------

(a)  The Certificate of Designation provides that the Applicable Rate on shares
     of AMPS, for each Dividend Period therefor after the Initial Dividend
     Period shall be the rate per annum that a commercial bank, trust company,
     or other financial institution appointed by the Trust advises results from
     implementation of the Auction Procedures. The Board of Trustees of the
     Trust has adopted a resolution appointing IBJ Schroder Bank & Trust Company
     as Auction Agent for purposes of the Auction Procedures. The Auction Agent
     hereby accepts such appointment and agrees that, on each Auction Date, it
     shall follow the procedures set forth in this Section 2 and the Auction
     Procedures for the purpose of determining the Applicable Rate for the AMPS
     for the next Dividend Period therefor. Each periodic operation of such
     procedures is hereinafter referred to as an "Auction."

(b)  All of the provisions contained in the Auction Procedures and the
     Settlement Procedures are incorporated herein by reference in their
     entirety and shall be deemed to be a part hereof to the same extent as if
     such provisions were fully set forth herein.

2.2  Preparation for Each Auction; Maintenance
     of Registry of Beneficial Owners.
     ---------------------------------

(a)  Pursuant to Section 2.5 hereof, the Trust shall not designate any Person to
     act as a Broker-Dealer without prior written approval of the Auction Agent
     (which approval shall not be withheld unreasonably).  At the time of
     closing of the initial issuance and sale of the AMPS (the "Closing"), the
     Trust shall provide the Auction Agent with a list of the Broker-Dealers
     previously approved by the Auction Agent and shall cause to be delivered to
     the Auction Agent for execution by the Auction Agent a Broker-Dealer
     Agreement signed by each such Broker-Dealer. The Auction Agent shall keep
     such list current and accurate and shall indicate thereon, or on a separate
     list, the identity of each Existing Holder, if any, whose most recent Order
     was submitted by a Broker-Dealer on such list and resulted in such Existing
     Holder continuing to hold or purchasing shares of AMPS. Not later than five
     days prior to any Auction Date for which any change in such list of Broker-
     Dealers is to be effective, the Trust shall notify the Auction Agent in
     writing of such change and, if any such change is the addition of a Broker-
     Dealer to such list, the Trust shall cause to be delivered to the Auction
     Agent for execution by the Auction Agent a Broker-Dealer Agreement signed
     by such Broker-Dealer. The Auction Agent shall have entered into a Broker-
     Dealer Agreement with each Broker-Dealer prior to the participation of any
     such Broker-Dealer in any Auction.

                                       4


(b)  In the event that the Auction Date for any Auction shall be changed after
     the Auction Agent shall have given the notice referred to in clause (vii)
     of Paragraph (a) of the Settlement Procedures, the Auction Agent, by such
     means as the Auction Agent deems practicable, shall give notice of such
     change to the Broker-Dealers not later than the earlier of 9:15 A.M. on the
     new Auction Date or 9:15 A.M. on the old Auction Date.

(c)  With respect to each Dividend Period that is a Special Dividend Period, the
     Trust may, at its sole option and to the extent permitted by law, by
     telephonic and written notice (a "Request for Special Dividend Period") to
     the Auction Agent and to each Broker-Dealer, request that the next
     succeeding Dividend Period for the AMPS will be a number of days (other
     than seven), evenly divisible by seven, and not fewer than seven nor more
     than 364 in the case of a Short Term Dividend Period or a number of whole
     years not greater than five years in the case of a Long Term Dividend
     Period, specified in such notice, provided that, the Trust may not give a
     Request for Special Dividend Period of greater than 28 days (and any such
     request shall be null and void) unless the Trust has given written notice
     thereof to S&P and received written confirmation from Moody's that such
     action would not impair the rating then assigned to the AMPS by Moody's and
     unless, for any Auction occurring after the Initial Auction, sufficient
     Clearing Bids were made in the last occurring Auction and unless full
     cumulative dividends, any amounts due with respect to mandatory redemptions
     and any Additional Dividends payable prior to such date have been paid in
     full. Such Request for Special Dividend Period, in the case of a Short Term
     Dividend Period, shall be given on or prior to the fourth Business Day but
     not more than seven Business Days prior to an Auction Date for the AMPS
     and, in the case of a Long Term Dividend Period, shall be given on or prior
     to the 14th day but not more than 28 days prior to the Auction Date for the
     AMPS. Upon receiving such Request for Special Dividend Period, the Broker-
     Dealers shall jointly determine whether given the factors set forth in
     paragraph 2(c)(iii) of the Certificate of Designation it is advisable that
     the Trust issue a Notice of Special Dividend Period for the AMPS as
     contemplated by such Request for Special Dividend Period and the Optional
     Redemption Price of the AMPS during such Special Dividend Period and the
     Specific Redemption Provisions and shall give the Trust and the Auction
     Agent written notice (a "Response") of such determination by no later than
     the third Business Day prior to such Auction Date. If the Broker-Dealers
     shall not give the Trust and the Auction Agent a Response by such third
     Business Day or if the Response states that given the factors referred to
     above it is not advisable that the Trust give a Notice of Special Dividend
     Period (as defined below) for the AMPS, the Trust may not give a Notice of
     Special Dividend Period in respect of such Request for Special Dividend
     Period. In the event the Response indicates that it is advisable that the
     Trust give a Notice of Special Dividend Period for the AMPS, the Trust may
     by no later than the second Business Day prior to such Auction Date give a
     notice (a "Notice of Special Dividend Period") to the Auction Agent, the
     Securities Depository and each Broker-Dealer, which notice will specify (i)
     the duration of the Special Dividend Period, (ii) the Optional Redemption
     Price as specified in the related Response and (iii) the Specific
     Redemption Provisions, if any, as specified in the related Response. The
     Trust shall not give a Notice of Special Dividend Period, or, if such
     Notice of Special Dividend Period shall have already been given, shall give
     telephonic and written notice of its revocation (a "Notice of Revocation")
     to the Auction Agent, each Broker-Dealer, and the Securities Depository


                                       5


     on or prior to the Business Day prior to the relevant Auction Date if (x)
     either the 1940 Act AMPS Coverage is not satisfied or the Trust shall fail
     to maintain S&P Eligible Assets and Moody's Eligible Assets each with an
     aggregate Discounted Value at least equal to the AMPS Basic Maintenance
     Amount in each case on each of the two Valuation Dates immediately
     preceding the Business Day prior to the relevant Auction Date on an actual
     basis and on a pro forma basis giving effect to the proposed Special
     Dividend Period (using as a pro forma dividend rate with respect to such
     Special Dividend Period the dividend rate which the Broker-Dealers shall
     advise the Trust is an approximately equal rate for securities similar to
     the AMPS with an equal dividend period), provided that in calculating the
     aggregate Discounted Value of Moody's Eligible Assets for this purpose, the
     Moody's Exposure Period shall be deemed to be one week longer, (y)
     sufficient funds for the payment of dividends payable on the immediately
     succeeding Dividend Payment Date have not been irrevocably deposited with
     the Auction Agent by the close of business on the third Business Day
     preceding the related Auction Date or (z) the Broker-Dealer(s) jointly
     advise the Trust that after consideration of the factors referred to above
     they have concluded that it is advisable to give a Notice of Revocation. If
     the Trust is prohibited from giving a Notice of Special Dividend Period as
     a result of the factors enumerated in clause (x), (y) or (z) of the
     preceding sentence or if the Trust gives a Notice of Revocation with
     respect to a Notice of Special Dividend Period, the next succeeding
     Dividend Period will be a 7-day Dividend Period. In addition, in the event
     sufficient Clearing Bids are not made in any Auction or an Auction is not
     held for any reason, the next succeeding Dividend Period will be a 7-day
     Dividend Period, and the Trust may not again give a Notice of Special
     Dividend Period (and any such attempted notice shall be null and void)
     until sufficient Clearing Bids have been made in an Auction with respect to
     a 7-day Dividend Period.

(d)  (i) Except as otherwise provided in paragraph 2(f) of the Certificate of
     Designation, whenever the Trust intends to include any net capital gains or
     other income subject to regular Federal income tax in any dividend on
     shares of AMPS, the Trust will notify the Auction Agent of the amount to be
     so included at least five Business Days prior to the Auction Date on which
     the Applicable Rate for such dividend is to be established. Whenever the
     Auction Agent receives such notice from the Trust, it will in turn notify
     each Broker-Dealer, who, on or prior to such Auction Date, in accordance
     with its Broker-Dealer Agreement, will notify its Existing Holders and
     Potential Holders believed to be interested in submitting an order in the
     Auction to be held on such Auction Date. Whenever the Trust includes any
     additional amounts in a dividend as provided in paragraph 2(f) of the
     Certificate of Designation, the Trust will notify the Auction Agent of such
     additional amounts to be so included in such dividend at least five
     Business Days prior to the applicable Dividend Payment Date. Whenever the
     Auction Agent receives such notice from the Trust it will in turn notify
     the Securities Depository and each Broker-Dealer, who, on or prior to the
     applicable Dividend Payment Date, in accordance with its Broker-Dealer
     Agreement, will notify its Existing Holders.

(ii) If the Trust makes a Retroactive Taxable allocation, the Trust will, within
     90 days (and generally within 60 days) after the end of its fiscal year for
     which a Retroactive Taxable Allocation is made provide notice thereof to
     the Auction Agent and to each holder of shares (initially the Securities
     Depository) during such fiscal year at

                                       6


     such holder's address as the same appears or last appeared on the share
     books of the Trust. The Trust will, within 30 days after such notice is
     given to the Auction Agent, pay to the Auction Agent (who will then
     distribute to such holders of shares of AMPS), out of funds legally
     available therefor, a cash amount equal to the aggregate Additional
     Dividend with respect to all Retroactive Taxable Allocations made to such
     holders during the fiscal year in question.

(e)  (i) On each Auction Date, the Auction Agent shall determine the Reference
     Rate and the Maximum Applicable Rate. If the Reference Rate is not quoted
     on an interest basis but is quoted on a discount basis, the Auction Agent
     shall convert the quoted rate to an Interest Equivalent, as set forth in
     paragraph 1 of the Certificate of Designation; or, if the rate obtained by
     the Auction Agent is not quoted on an interest or discount basis, the
     Auction Agent shall convert the quoted rate to an interest rate after
     consultation with the Trust as to the method of such conversion. Not later
     than 9:30 A.M. on each Auction Date, the Auction Agent shall notify the
     Trust and the Broker-Dealers of the Reference Rate so determined and the
     Maximum Applicable Rate.

(ii) If the Reference Rate is the applicable "AA" Composite Commercial Paper
     Rate and such rate is to be based on rates supplied by Commercial Paper
     Dealers and one or more of the Commercial Paper Dealers shall not provide a
     quotation for the determination of the applicable "AA" Composite Commercial
     Paper Rate, the Auction Agent shall immediately notify the Trust so that
     the Trust can determine whether to select a Substitute Commercial Paper
     Dealer or Substitute Commercial Paper Dealers to provide the quotation or
     quotations not being supplied by any Commercial Paper Dealer or Commercial
     Paper Dealers. The Trust shall promptly advise the Auction Agent of any
     such selection. If the Trust does not select any such Substitute Commercial
     Paper Dealer or Substitute Commercial Paper Dealers, then the rates shall
     be supplied by the remaining Commercial Paper Dealer or Commercial Paper
     Dealers.

(iii) If, after the date of this Agreement, there is any change in the
     prevailing rating of AMPS by either of the rating agencies (or substitute
     or successor rating agencies) referred to in the definition of the Maximum
     Applicable Rate, thereby resulting in any change in the corresponding
     applicable percentage for the AMPS, as set forth in said definition (the
     "Percentage"), the Trust shall notify the Auction Agent in writing of such
     change in the Percentage prior to 9:00 A.M. on the Auction Date for AMPS
     next succeeding such change. The Percentage for the AMPS on the date of
     this Agreement is as specified in paragraph 11(a)(vii) of the Certificate
     of Designation. The Auction Agent shall be entitled to rely on the last
     Percentage of which it has received notice from the Trust (or, in the
     absence of such notice, the Percentage set forth in the preceding sentence)
     in determining the Maximum Applicable Rate as set forth in Section
     2.2(e)(i) hereof.

(f)  (i) The Auction Agent shall maintain a current registry of the beneficial
     owners of the shares of the AMPS who shall constitute the Existing Holders
     for purposes of each Auction. The Trust shall use its best efforts to
     provide or cause to be provided to the Auction Agent within ten days
     following the date of Closing a list of the initial Existing Holders of the
     AMPS, and the Broker-Dealer of each such Existing

                                       7


     Holder through which such Existing Holder purchased such shares. The
     Auction Agent may rely upon, as evidence of the identities of the Existing
     Holders, such list, the results of each Auction and notices from any
     Existing Holder, the Agent Member of any Existing Holder or the Broker-
     Dealer of any Existing Holder with respect to such Existing Holder's
     transfer of any shares of AMPS to another Person.

(ii) In the event of any partial redemption of any shares of AMPS, upon notice
     by the Trust to the Auction Agent of such partial redemption, the Auction
     Agent shall promptly request the Securities Depository to notify the
     Auction Agent of the identities of the Agent Members (and the respective
     numbers of shares) from the accounts of which shares have been called for
     redemption and the person or department at such Agent Member to contact
     regarding such redemption, and at least two Business Days prior to the .
     Auction preceding the date of redemption with respect to the shares being
     partially redeemed, the Auction Agent shall request each Agent Member so
     identified to disclose to the Auction Agent (upon selection by such Agent
     Member of the Existing Holders whose shares are to be redeemed) the number
     of shares of the AMPS of each such Existing Holder, if any, to be redeemed
     by the Trust; provided the Auction Agent has been furnished with the name
     and telephone number of a person or department at such Agent Member from
     which it is to request such information. If necessary to procure such
     information, the Auction Agent shall deliver to each Agent Member a
     facsimile copy of the Purchaser's Letter of each Existing Holder
     represented by such Agent Member, which authorizes and instructs such Agent
     Member to release such information to the Auction Agent. In the absence of
     receiving any such information with respect to an Existing Holder, from
     such Existing Holder's Agent Member or otherwise, the Auction Agent may
     continue to treat such Existing Holder as the beneficial owner of the
     number of shares of the AMPS shown in the Auction Agent's registry of
     beneficial owners.

(iii) The Auction Agent shall register a transfer of the beneficial ownership of
     shares of the AMPS from an Existing Holder to another Person only if such
     transfer is made to a Person that has delivered a signed Purchaser's Letter
     to the Auction Agent and only if (A) such transfer is pursuant to an
     Auction or (B) if such transfer is made other than pursuant to an Auction,
     the Auction Agent has been notified in writing in a notice substantially in
     the form of Exhibit D to the Broker-Dealer Agreement, by such Existing
     Holder, the Agent Member of such Existing Holder, or the Broker-Dealer of
     such Existing Holder of such transfer. The Auction Agent is not required to
     accept any notice of transfer delivered for an Auction unless it is
     received by the Auction Agent by 3:00 P.M. on the Business Day next
     preceding the applicable Auction Date. The Auction Agent shall rescind a
     transfer made on the registry of the beneficial owners of any shares of
     AMPS if the Auction Agent has been notified in writing in a notice
     substantially in the form of Exhibit E to the Broker-Dealer Agreement by
     the Agent Member or the Broker-Dealer of any Person that (i) purchased any
     shares of AMPS and the seller failed to deliver such shares or (ii) sold
     any shares of AMPS and the purchaser failed to make payment to such Person
     upon delivery to the purchaser of such shares.

                                       8


(g)  The Auction Agent may request that the Broker-Dealers, as set forth in
     Section 3.2(c) of the Broker-Dealer Agreements, provide the Auction Agent
     with a list of their respective customers that such Broker-Dealers believe
     are Existing Holders of shares of AMPS. The Auction Agent shall keep
     confidential any such information and shall not disclose any such
     information so provided to any Person other than the relevant Broker-Dealer
     and the Trust, provided that the Auction Agent reserves the right to
     disclose any such information if it is advised by its counsel that its
     failure to do so would be unlawful.

2.3  Auction Schedule.
