AMENDED AGREEMENT AMONG INSUREDS
UNDER D&O/E&O INSURANCE POLICY


	AGREEMENT made as of September 7, 2004, by and among
the investment companies (which include all series thereof) listed
on Schedule A (the "Funds") and the corporations (the "Service
Providers") listed on Schedule A, being providers of services to the
Funds, on the date hereof consisting of Aquila Investment Management
LLC ("Aquila"), Aquila Distributors, Inc. and STCM Management Company,
Inc. (the Funds and Service Providers being referred to collectively
as the "Parties" and separately as a "Party").

	WHEREAS, the Parties are parties to an Agreement among Insureds
dated as of May 9, 2001, as from time to time amended, and wish to
enter into this Agreement to amend their prior agreement to provide
for the changes that have occurred as to the insurance involved;

	WHEREAS the Funds, their Trustees (the "Trustees") and officers
and the Service Providers and their directors and officers were jointly
insured under a Directors and Officers/Errors and Omissions Liability
Insurance Policy (the "Original Policy") issued by ICI Mutual Insurance
Company (the "Insurer"), providing a $10 million ($10,000,000) limit of
liability in the aggregate (subject to exclusions and deductibles)
during the period May 9, 2001 to May 9, 2002, renewed for successive
periods thereafter;

	WHEREAS, the Original Policy has been amended, including an
amendment effective September 7, 2004 to provide four levels of insurance
(each, a "Level") as set forth on Schedule B to this Agreement, with
varying amounts of coverage and differing insureds, the first Level
applying to all Parties, the second and third Levels applying to two
separate groups of named Funds and the fourth level applying to all Funds,
each Level providing coverage only when coverage at prior Levels has been
exhausted;

	WHEREAS, the Original Policy as so revised is referred to herein
as the "Policy";

	NOW, THEREFORE, in consideration of the mutual covenants set
forth below, the Parties agree as follows:

The premiums for each level of the Policy, including tax,
shall be allocated among the Parties as shown on Schedule B
hereto.  As the Policy is for a one-year term and is renewed
annually, Schedule B and premium allocations shall be revised
upon each renewal of the Policy for each additional term.
All additional costs of each Level of the Policy shall be
allocated among the Parties in the same ratio as the allocation
of the Policy premiums for that Level.  Notwithstanding anything
herein to the contrary, the premium allocation to each Fund
shall be determined, and revised as appropriate, in compliance
with part (d)(7)(ii) of Rule 17d-1 under the Investment Company
Act of 1940, as amended (the "1940 Act").

In the event that losses covered by a Level of the Policy
("Covered Losses") are suffered by one or more Parties that exceed
 in the aggregate the limit of liability of the Policy, the limit on
the amount retained by each Party from its recovery from that Level
shall be determined as follows:

		a)	Base Coverage

There shall be computed a benefit allocation for each Party
(its "Base Coverage") determined by applying to the Policy's
limit of liability for that Level the allocation percentage
for that Level shown for that Party in Schedule B;

Each Party suffering a Covered Loss shall be entitled to a
 benefit of up to the amount of its Base Coverage.

Proportional Allocation to Remaining Losses

The amount of any benefit ("Remaining Coverage") remaining
after application of Base Coverages to Covered Losses shall
be allocated to those Covered Losses (the "Remaining Losses")
 remaining after application of Base Coverages.

The Remaining Coverage retained by each Party shall be
limited to the proportion of all Remaining Coverage which
the amount of that party's Remaining Losses bears to the
Remaining Losses of all Parties.

The amount that a Party may recover shall be adjusted if
necessary to reflect the fact that there is no priority in
time of any claim or recovery.

A newly created investment company (a "New Fund") having
an administrator, investment adviser or sub-adviser that is,
or is an "affiliated person" (as defined in the 1940 Act) of, a
Service Provider may become a named Insured under and as defined
in the Policy, and the Trustees and officers of the New Fund may
become insureds, provided that the New Fund causes this Agreement
to be signed on its behalf as of the date that it agrees to the
terms and conditions of this Agreement; such New Fund shall be
deemed to be added to Schedule A.  A Fund may become an insured
under a Level of the Policy as to which it was not previously
insured, and the Trustees and officers of that Fund may become
insureds under that Level.  A party that is an affiliated person
of, or an affiliated person of an affiliated person of, a Service
Provider (a "New Service Provider") may become a named insured
under the Policy, and its directors and officers may become Insureds,
provided that the New Service Provider causes this Agreement to be
signed on its behalf as of the date that it agrees to the terms and
 conditions of this Agreement; such New Service Provider shall
thereupon be deemed to be added to Schedule A.  In any such event,
a new Schedule B hereto, revised by Aquila to reflect changed
allocations, shall be substituted for the then-current Schedule B.

Aquila shall take all steps necessary or appropriate to maintain
coverage under the Policy, including, without limitation, providing
the Insurer with all notices necessary or appropriate under the Policy
and maintaining or overseeing payment of premiums so that the Policy
remains continuously in effect.

Aquila shall provide the Trustees with copies of all notices
under the Policy appropriate for informing the Trustees of
coverage thereunder, including, without limitation:

All notices to the Insurer concerning potential liability under the Policy;

	All notices to the Insurer concerning acquisitions, mergers and
material changes; and

	All notices of the Insurer concerning cancellation or limitation
of coverage under the Policy.

Aquila shall, to the extent practicable, assure that all current
or former Trustees or officers covered under the Policy shall have at
least three months' notice of any policy amendment or replacement policy
which reduces or restricts coverage of such persons under the Policy.  No
notice need be given to former Trustees or officers who have not been
Trustees or officers for at least six years.

	8. Each of the Parties understands and agrees that the obligations
of the Funds under this Agreement are not binding upon any shareholder
or Trustee of any Fund, but bind only the Funds and their property.
Each of the Parties represents that it has notice of the provisions of
the Declarations of Trust of the Funds that disclaim shareholder and
Trustee liability for acts and obligations of the Funds.
