Section
10.  Election under Revenue
Procedure 2003-84.





(1)
            The
      Election.




(a)
            The
      Trust is making an election  (the “Monthly Closing Election”)
      under Revenue Procedure 2003-84, effective as of the later of the date the
      Trust has more than one owner for tax purposes and the date the Trust has
      more than a de
      minimis amount of assets (the “Start-Up Date”).  This
      election is binding on all present and future Holders and Beneficial

      for federal income tax purposes and each of their nominees (each, a
      “Partner” for this purpose) and each Partner, by acceptance of its
      Certificate or interest therein, is deemed to consent to this
      election.




(b)

      Trust shall not have any income producing assets and shall not earn any
      income prior to its Start-Up Date.  The Trust shall not file a
      tax return for the period prior to the Start-Up
  Date.




(c)
            Notwithstanding
      Section 2.5(b) of the Standard Terms, the Trust shall not (and no person
      is authorized on behalf of the Trust to) elect to be an association
      taxable as a corporation for federal income tax purposes nor make an
      election under section 761(a) of the Code to be excluded from subchapter K
      of chapter 1 of the Code.




(d)
            Section
      2.5(e) of the Standard Terms is hereby replaced in its entirety with the
      following:




For
purposes of maintaining capital accounts and all income tax purposes, including
the Trust’s deemed closing of its books at the end of each calendar month under
Treasury Regulation § 1.706-1(c)(2) that is required by section 6 of Revenue
Procedure 2003-84, the Trust’s tax-exempt income, taxable income, gain, loss,
deduction, and credit will be allocated as for federal income tax and applicable
state and local franchise and income tax purposes as follows:




(i)
            Interest
      on the Bonds (including accrued original issue discount) for any period
      shall be allocated:




(1)
            first, to the
      Holders of Variable Certificates, an amount equal to accrued interest
      distributable for such period on the Variable Certificates at the Variable
      Certificates Rate, and






(2)
            second, to the
      Holders of the Related Inverse Certificates, the remaining interest on the
      Bonds;




(ii)
            Gain
      on the sale or redemption of the Bonds of any Maturity shall be
      allocated:




(1)
            to
      the extent any gain on the sale of such Bonds is treated as ordinary
      income under Section 1276 of the Code, 100% to the Holders of the Related
      Inverse Certificates,




(2)
            to
      the extent any gain on the sale or deemed sale of such Maturity of Bonds
      is required to be shared with the Holders of the Variable Certificates
      pursuant to this Agreement, to the Holders of the Variable Certificates
      that share in the distribution of such amounts,
  and




(3)
            to
      the extent of the balance of all other gain, to the Holders of the Related
      Inverse Certificates;




(iii)
            Loss
      recognized on the sale of the Bonds of any Maturity shall be allocated
      100% to the Holders of the Related Inverse Certificates (except to the
      extent the loss is borne economically by other Partners in which case it
      will be allocated to that extent to such other
  Partners);




(iv)
            Unrecognized
      loss on any in-kind distribution of the Bonds of any Maturity shall be
      allocated to the Holders of Variable Certificates and Related Inverse
      Certificates in a manner that reflects their respective interests in the
      Trust and the Bonds, their shares of the Bonds distributed, and the
      effects on their respective interests of such distribution (taking account
      of all facts and circumstances);
and




(v)
            All
      expenses of the Trust (including all Amortized Premium on the Bonds to the
      extent treated as a separate item of expense of the Trust) shall be
      allocated 100% to the Holders of the Related Inverse
      Certificates.




(vi)
            All
      of the allocations set out above are intended to be made in accordance
      with section 704(b) of the Code.  If allocation of the Trust’s
      tax-exempt income, taxable income, gain, loss, deduction, and credits
      provided above would not be in accordance with section 704(b) of the Code,
      then allocations shall be made in a manner that is in accordance with
      section 704(b) of the Code.  If the Trustor believes in its sole
      judgment that such other allocations are required it shall promptly give
      notice to Holders (or, in the case of Certificates held by a regulated
      investment company (as defined in Section 851(a) of the Code) (each, a
      “RIC”) with respect to which an election is in place for a manager (the
      “Electing Manager”) to be responsible for collecting, retaining, and
      providing beneficial ownership information to the Internal Revenue Service
      (the “IRS”), the Trustor shall promptly give notice to the Electing
      Manager).




(2)
            Limitations on
      Activities and Income and Expense of the
  Trust.




Notwithstanding
anything herein or in the Standard Terms to the contrary:




(a)
            the
      Trust shall not acquire any asset unless the Trustee has received an
      Officer’s Certificate of the Trustor that the acquisition of that asset
      will not cause less than 95 percent of the Trust’s gross income (for this
      purpose, including the gross amount of interest income that is excluded
      from gross income) to be (or reasonably expected to be)
    from:




(i)
            interest
      on tax-exempt obligations as defined in section 1275(a)(3) of the Code and
      Treasury Regulation § 1.1275-1(e),




(ii)
            exempt-interest
      dividends as defined in section 852(b)(5) of the Code that are paid by a
      RIC, and




(iii)
            gain
      from the sale, redemption, or other disposition of assets generating the
      income described in clauses (i) and (ii), above, and income from the
      temporary investment (for a period no greater than seven months) of the
      proceeds of the disposition, but only if the assets that are sold,
      redeemed, or disposed are original assets of the Trust.  For
      this purpose, an asset is an original asset of the Trust if the asset is
      contributed to the Trust or is acquired with capital contributed to the
      Trust (and not with the proceeds of the sale, redemption, or other
      disposition of a Trust asset).




The Trust
shall distribute (or make payments of expenses with) the proceeds of any of the
assets that are sold, redeemed, or disposed of, and shall not reinvest such
proceeds unless otherwise permitted and in any event shall not invest such
proceeds other than (1) for a temporary period (not exceeding seven months)
prior to distribution (or payment) in investments having a remaining maturity of
less than seven months and maturing on or before the next Variable Certificates
Interest Payment Date (or date when expenses are expected to be paid) or (2)
reinvestment in a fund commonly known as a tax-exempt money market fund (very
generally, a RIC that seeks to maintain a stable net asset value per share of
$1.00 and pay solely exempt-interest dividends as defined in section 852(b)(5)
of the Code), but nothing in this sentence implies that any such right to
reinvest exists.  The Trust may assume that amounts treated as
interest for federal income tax purposes on fixed income investments for which
an Opinion of Counsel was rendered satisfy the requirement of clause (i) of
Section (2)(a) until it has received notice from its tax advisors or the Trustor
or Remarketing Agent to the contrary.




(b)
            The
      Trust shall not incur any liability or expense, if doing so would prevent
      substantially all of the Trust’s expenses and deductions from being
      properly allocable to:




(i)
            producing,
      collecting, managing, protecting, and conserving the income described in
      Section (a)(i), (ii), or (iii),
above,




(ii)
            acquiring,
      managing, conserving, maintaining, or disposing of property held for the
      production of the income described in Section 8(2)(a)(i), (ii), or (iii),
      above, and




(iii)
            servicing
      the equity in the Trust, and




(iv)
            Payments
      of Remarketing and Liquidity Charges and Trustee Fees comply with Section
      8(2)(b).  Furthermore, for purposes of Section 8(2)(b), the
      costs of collecting, managing, computing, and supplying the information
      required, under Revenue Procedure 2003-84, to be provided to the IRS and
      to the Partners, shall not be taken into
  account.




(3)
            Initial
      Filing.




(a)
            In
      connection with its formation, the Trust shall obtain an employer
      identification number.  The Trustor and, at the Trustor’s
      direction, the Trustee, and each of their accountants, are each authorized
      to obtain such number and each of the foregoing is authorized to delegate
      such authority to its agents.  Each Partner, by acceptance of
      its Certificate or interest therein, is deemed to consent to the
      foregoing.




(b)
            The
      Trust shall file an abbreviated Form 1065, “U.S. Return of Partnership
      Income,” as required by, and in the format outlined in section 8.01 of,
      Revenue Procedure 2003-84, for its first taxable year as soon as
      reasonably possible after the Start-Up Date but in no event later than the
      date that the partnership's income tax return for that taxable year would
      ordinarily be due.  The Trustor and, at the Trustor’s direction,
      the Trustee, and each of their accountants, are each authorized to sign
      the abbreviated Form 1065, and each of the foregoing is authorized to
      delegate such authority to its agents.  Each Partner, by
      acceptance of its Certificate or interest therein, is deemed to consent to
      the foregoing and to authorize the filing of the abbreviated Form 1065 on
      behalf of the Trust and itself.  Copies of the abbreviated Form
      1065 will be made available to Partners upon
  request.




(4)
            Information Reporting
      and Record Retention.




(a)
            The
      Trust shall, within 45 days of a request by the IRS or a Partner (or a
      Beneficial Owner or nominee of a Beneficial Owner of a Certificate), make
      available all the information necessary to compute a Partner’s monthly
      tax-exempt income, taxable income, gain, loss, deduction, or credit,
      including sufficient information for a partner to determine the portion of
      the tax-exempt interest that may be subject to the alternative minimum tax
      and information regarding each Partner’s share of any bond premium
      amortization under section 171 of the Code, any market or original issue
      discount, and capital gain or loss.  The Trust shall not charge
      any fee to the IRS or a Partner for providing the information required to
      be provided by this paragraph.  If any Partner specifically
      requests such information for any tax reporting reason, however, the
      Trustor may charge such Partner a reasonable fee (disclosed in advance)
      but not the IRS) for providing any information required to be provided to
      or on behalf of such Partner by Section
8(4)(a).




(b)
            Except
      in the case of a RIC with respect to which a manager or advisor (an
      “Electing Manager”) has elected under section 8.04 of Revenue Procedure
      2003-84 to be responsible for collecting, retaining and providing to the
      IRS the beneficial ownership information otherwise required to be
      collected, retained and provided to the IRS, each Holder, Beneficial Owner
      of a Certificate or Partner on whose behalf another person holds an
      interest in a Certificate as a nominee shall, and by its acceptance of its
      Certificate or any interest therein is deemed to agree to, notify the
      Trustor on behalf of the Trust of its beneficial ownership of a
      Certificate and provide the Trustor on behalf of Trust all information as
      required by section 8.04 of Revenue Procedure 2003-84 substantially

a material risk that the Trust does not qualify for the Monthly Closing
Election.




Section
12.  Trustor’s Obligations with
respect to Revenue Procedure 2003-84.




(1)
            Obligations of the
      Trustor.  Notwithstanding anything herein or in the

      income, gain, loss, deduction, or credit, including sufficient information
      for a Partner to determine the portion of the interest which is excluded
      from gross income for purposes of federal income taxes that may be subject
      to the alternative minimum tax and information regarding each partner’s
      share of any bond premium amortization under section 171 of the Code, any

      provide information for as long as the Trust is required to provide such
      information.; and




(e)
            at
      the request of the Trustee, confirm whether or not an expense or liability

      provisions of Section 8(2)(b)
hereof.




(2)
            Cooperation.  The

      Agreement.




Section
13.   Section 3.2(a) of the Standard Terms is hereby
amended and restated in its entirety to read as follows:

respect to each Series, interest on the Bonds shall be distributed as provided
in Section 3.2(b) on each Semi-Annual Interest Payment Date; provided, that if the Trustee
on the Semi-Annual  Interest Payment Date has not confirmed receipt of
such interest in immediately available funds, notwithstanding any other
provision hereof, such distribution may be delayed until the Business Day on
which the Trustee confirms receipt of immediately available funds; and provided
further that if the Semi-Annual  Interest Payment Date is not a
Business Day, then the interest distribution otherwise payable on such
Semi-Annual  Interest Payment Date shall be payable on the Business
Day next succeeding such Semi-Annual  Interest Payment Date or the
Business Day succeeding such Semi-Annual  Interest Payment Date on
which the Trustee confirms receipt of interest in immediately available funds,
whichever is later, as though paid on such Semi-Annual Interest Payment
Date.





Interest
payments on the Bonds received by the Trustee during each such semi–annual
period prior to a Semi-Annual Interest Payment Date (other than interest being
paid in connection with a redemption of Bonds) shall be deposited by the Trustee
into the Collection Account and remain uninvested.  Upon termination
of the Trust and payment in full of all interest payable on the Variable
Certificates, any amounts remaining in the Collection Account shall be
distributed to the Holders of the Inverse Certificates.





Notwithstanding
the foregoing provisions with respect to the semi-annual payment of interest on
the Certificates, the Trustee will distribute payments identified to the Trust
by the paying agent for the Bonds as payments of principal and premium on the
Bonds not later than the Business Day following Trustee’s receipt of such
payments, as required by the Standard Terms.





The
Trustor hereby grants to the Trustee a first-priority security interest in the
Collection Account, the Bonds and other financial assets credited thereto, and
all proceeds thereof.”





A new
Section 3.2(c) is hereby added to the Standard Terms immediately following
Section 3.2(b) thereof, as follows:





“(c)           With
respect to each Series, amounts received by the Trustee with respect to the
Related Bonds that have been identified to the Trustee as payments received from
or on behalf of the applicable Issuer (rather than from the related Principal
Credit Source), after reimbursement in full of the related Principal Credit
Source for the amount of the related drawing(s) on the applicable Credit
Enhancement, shall be distributed to Holders of the Inverse Certificates of such
Series.”





Section
14.   Section 3.3 of the Standard Terms is hereby amended
by adding, following clause (d) thereof, the following clause (e):





(e)           Any
change in the Remarketing Agent Fee Rate and the Liquidity Fee Rate and any
material change in the Trustee Fee Rate shall require the consent of the Inverse
Certificates Holder.





Section
15.   Section 3.4 of the Standard Terms is hereby amended
and restated in its entirety to read as follows:





“Section
3.4.                                Interest Distributable on
Variable Certificates.  Interest distributions on the Variable
Certificates will be made on each Semi-Annual Interest Payment Date or other
date on which interest is distributed pursuant to Section 3.2(a) (each, a
“Variable Certificates Interest Payment Date”), in arrears for interest which
shall have accrued in the Calculation Period ending on the day before the
related Semi-Annual Interest Payment Date and shall be the amount determined as
the “Variable Certificates Interest Amount” by the Trustee.  Such
interest shall be payable to Holders of record as of the related Regular Record
Date to the extent of interest on the Bonds, if any, received and distributed by
the Trustee on or about such Variable Certificates Interest Payment Date
pursuant to Section 3.2.  The Variable Certificates Interest Amount in
respect of each Calculation Period for each Variable Certificate shall be
calculated on the Actual/Actual Basis by multiplying the Stated Amount of such
Variable Certificates by the Variable Certificates Rate or Rates in effect from
time to time for such Calculation Period.”




Section
16.   Section 5.2(d)(vi) of the Standard Terms is amended
and restated to read in its entirety as follows:

the Variable Certificates Rate multiplied by the Related Allocation Fraction on
the Mandatory Tender Date:






(A)           the Trustee shall instruct the Remarketing Agent to sell

Provider to such execution and delivery of additional Variable Certificates and
evidence that the Amount Available under the Liquidity Agreement has been
increased to reflect the issuance of the additional Variable Certificates in
accordance with the terms of the Standard Terms and the Liquidity
Agreement.




The
Trustor shall also deliver to the Trustee a certificate of the Trustor
demonstrating that the Variable Certificates Rate, following the delivery of the
additional Variable Certificates, (y) if such delivery is on a Variable
Certificates Interest Payment Date, will not exceed the Maximum Variable
Certificates Rate or (z) if such delivery is on an Rate Determination Date, will
not exceed the Maximum Variable Certificates Rate assuming that the issuance of
the additional Variable Certificates had occurred as of the immediately
preceding Bond Interest Payment Date.

and to the Securities Depositories for transmission to the Holders of
Certificates.

the Remarketing Agent to sell a portion of the Bonds of each Maturity sufficient
in the aggregate to pay the accrued and unpaid Trustee Fees, the accrued and
unpaid Remarketing and Liquidity Charges and the Stated Amount of such Liquidity

such proxies, weighted by the Stated Amount of the Variable Certificates and the
Stated Amount of Inverse Certificates held by each Holder; provided, however,

Bond
Counsel Opinion:





Federal
      and State Income Taxes:
            Bond
      Counsel rendered its opinion at the time of original issuance of the
      Underlying Bonds generally to the effect that, based on then existing
      laws, regulations and decisions and subject to certain conditions,
      interest on the Underlying Bonds is excludable from gross income for
      federal income tax purposes, except during any period while an Underlying
      Bond is held by a “substantial user” of the project or a “related person”
      within the meaning of Section 147(a) of the Internal Revenue of 1986, as
      amended (the “Code”).  No opinion, however, was expressed
      regarding the treatment of the interest on the Underlying Bonds under the
      tax laws of the State of Kansas.AMT:
            The
      opinion of Bond Counsel, rendered as described above, also was generally
      to the effect that, based on then existing laws, regulations and decisions
      and subject to certain conditions, interest on the Underlying Bonds is an
      item of tax preference for purposes of the federal alternative minimum tax
      imposed on individuals and
corporations.
