                            "BUILT TO RIDE THE WAVES"

                                                                    August, 2006

Dear Fellow Shareholder:

      As you are no doubt aware, the financial  markets have certainly had their
fair share of crests and troughs  recently - one day the markets are up, and the
next day, they are down. Riding these waves is not always easy for investors.

      The  management  of  Tax-Free  Fund  of  Colorado  understands  investors'
apprehension  when it comes to  fluctuations  with your  hard-earned  investment
monies.  And, this concern is  especially  pertinent as it relates to saving for
and funding your retirement.

      With this very  real and  inevitable  concern  in mind,  Tax-Free  Fund of
Colorado has endeavored to structure the Fund to "ride the waves" with the least
upset to investors as possible. How do we go about seeking to accomplish this?

INVESTMENT QUALITY

      No matter what  quality  rating  exists with a security,  it will still be
subject  to  market   fluctuations.   However,  our  experience  has  been  that
top-quality  ratings  do  not  fluctuate  as  much  as  lower  quality  ratings.
Furthermore,  when they do fluctuate,  they tend to fluctuate less and return to
their base market price at a quicker rate than lower-grade securities.

      In accordance  with the Fund's  prospectus,  Tax-Free Fund of Colorado can
only  purchase  investment-grade  securities  - those within the top four credit
quality  ratings - AAA,  AA, A and Baa. In point of practice,  however,  we have
consistently sought to have the bulk of the portfolio securities invested within
the top two  grades - AAA and AA.  On June  30,  2006,  98.5%  of the  portfolio
consisted of AAA and AA rated securities.

INTERMEDIATE MATURITY

      As we have  emphasized  in the past,  long-term  bonds  tend to  produce a
higher return than short-term  bonds.  However,  such longer maturity bonds also
tend to experience a higher degree of volatility in their price.

      Tax-Free Fund of Colorado balances out longer-term  maturities by having a
portion of the Fund's investments in shorter-term maturities.  Through utilizing
a blend of  maturities - both  shorter-term  and  longer-term - Tax-Free Fund of
Colorado attempts to provide a satisfactory  level of return without  subjecting
the share price to excessive swings as interest rates increase and decrease.  We
feel  that  this  focus  on  keeping  the  average  of   maturities   relatively
intermediate in term takes the best that each

                      NOT A PART OF THE SEMI-ANNUAL REPORT



investment has to offer - gaining stability from the shorter-term maturities and
higher yields from the longer-term maturities.

DIVERSIFICATION OF THE PORTFOLIO

      To the maximum  extent  possible,  Tax-Free  Fund of  Colorado  strives to
invest in as many projects as possible throughout the state. The portfolio might
be comprised of a school district bond in Denver, a transportation bond in Grand
Junction  and a housing  bond in  Springfield.  In this way, we strive to ensure
that  no one  project,  type of  project,  or area of the  State  can  have  any
significant adverse influence upon your investment in the Fund.

TAX-FREE INCOME

      No matter  what return  Tax-Free  Fund of  Colorado  provides,  it must be
remembered  that  you  would  have to earn  significantly  more  from a  taxable
investment  in  order  to be  equal  to what  you get to  keep  from a  tax-free
investment.

      As an  example,  you would have to earn 6.5%* on a taxable  investment  in
order to equal the tax-free level of 4%.

      Keep this  illustration  in mind the next time you  examine the yield that
Tax-Free Fund of Colorado offers you. You will find that a 3%, 4% or 5% tax-free
yield  looks   considerably  more  attractive  to  you  when  you  consider  the
implications of taxes.

SUMMARY

      The Fund uses this combination of quality,  maturity,  and diversification
as it  seeks  to  provide  you with as high a level  of  tax-free  income  as is
consistent with preservation of capital.

      As we are sure you are aware, there is no way to take ALL the waves out of
investing.  But, you can rest assured that Tax-Free Fund of Colorado continually
strives to do its very best to make sure your ride is as smooth as possible.

                                   Sincerely,


/s/ Diana P. Herrmann                      /s/ Lacy B. Herrmann

                            TAX-FREE FUND OF COLORADO
                          NOTES TO FINANCIAL STATEMENTS
                            JUNE 30, 2006 (UNAUDITED)

1. ORGANIZATION

      Tax-Free  Fund of  Colorado  (the  "Fund"),  a  non-diversified,  open-end
investment company, was organized in February,  1987 as a Massachusetts business
trust and commenced  operations on May 21, 1987. The Fund is authorized to issue
an  unlimited  number of shares  and,  since its  inception  to April 30,  1996,
offered  only one class of shares.  On that date,  the Fund began  offering  two
additional classes of shares, Class C and Class Y shares. All shares outstanding
prior  to that  date  were  designated  as Class A  shares  and are sold  with a
front-payment  sales charge and bear an annual  distribution fee. Class C shares
are sold with a  level-payment  sales charge with no payment at time of purchase
but level service and  distribution  fees from date of purchase through a period
of six years thereafter. A contingent deferred sales charge of 1% is assessed to
any Class C  shareholder  who redeems  shares of this Class within one year from
the date of purchase.  Class C Shares,  together with a pro-rata  portion of all
Class  C  Shares   acquired   through   reinvestment   of  dividends  and  other
distributions paid in additional Class C Shares,  automatically convert to Class
A Shares  after 6 years.  The Class Y shares are only  offered  to  institutions
acting for an investor in a fiduciary,  advisory,  agency,  custodian or similar
capacity and are not offered  directly to retail  investors.  Class Y shares are
sold at net asset value without any sales charge,  redemption  fees,  contingent
deferred  sales charge or  distribution  or service fees. On April 30, 1998, the
Fund  established  Class I shares,  which  are  offered  and sold  only  through
financial intermediaries and are not offered directly to retail investors. Class
I Shares are sold at net asset value without any sales charge,  redemption fees,
or contingent  deferred sales charge.  Class I Shares carry a  distribution  and
service  fee.  As of the report  date no Class I Shares  were  outstanding.  All
classes of shares  represent  interests in the same portfolio of investments and
are identical as to rights and  privileges but differ with respect to the effect
of sales  charges,  the  distribution  and/or  service fees borne by each class,
expenses  specific to each class,  voting  rights on matters  affecting a single
class and the exchange privileges of each class.

2. SIGNIFICANT ACCOUNTING POLICIES

      The following is a summary of significant  accounting policies followed by
the Fund in the  preparation  of its financial  statements.  The policies are in
conformity with accounting principles generally accepted in the United States of
America for investment companies.

a)    PORTFOLIO VALUATION:  Municipal securities which have remaining maturities
      of more than 60 days are valued at fair value each business day based upon
      information provided by a nationally prominent independent pricing service
      and periodically  verified through other pricing services.  In the case of
      securities for which market quotations are readily  available,  securities
      are valued by the pricing service at the mean of bid and asked quotations.
      If market  quotations  or a  valuation  from the  pricing  service  is not
      readily available, the security is valued at fair value determined in good
      faith under procedures established by and under the general supervision of
      the Board of



      Trustees.  Securities  which  mature  in 60  days or less  are  valued  at
      amortized  cost if their term to  maturity at purchase is 60 days or less,
      or by amortizing their unrealized appreciation or depreciation on the 61st
      day prior to  maturity,  if their term to maturity at purchase  exceeds 60
      days.

b)    SECURITIES   TRANSACTIONS  AND  RELATED  INVESTMENT   INCOME:   Securities
      transactions  are  recorded on the trade date.  Realized  gains and losses
      from  securities  transactions  are reported on the identified cost basis.
      Interest income is recorded daily on the accrual basis and is adjusted for
      amortization  of  premium  and  accretion  of  original  issue and  market
      discount.

c)    FEDERAL  INCOME  TAXES:  It is the  policy  of the  Fund to  qualify  as a
      regulated  investment  company by  complying  with the  provisions  of the
      Internal Revenue Code applicable to certain investment companies. The Fund
      intends to make  distributions of income and securities profits sufficient
      to relieve it from all, or  substantially  all,  Federal income and excise
      taxes.

d)    MULTIPLE   CLASS   ALLOCATIONS:   All   income,   expenses   (other   than
      class-specific  expenses), and realized and unrealized gains or losses are
      allocated  daily to each class of shares  based on the relative net assets
      of each class.  Class-specific  expenses,  which include  distribution and
      service  fees and any other items that are  specifically  attributed  to a
      particular class, are charged directly to such class.

e)    USE OF ESTIMATES:  The  preparation of financial  statements in conformity
      with  accounting  principles  generally  accepted in the United  States of
      America requires  management to make estimates and assumptions that affect
      the  reported   amounts  of  assets  and  liabilities  and  disclosure  of
      contingent assets and liabilities at the date of the financial  statements
      and the  reported  amounts of increases  and  decreases in net assets from
      operations during the reporting  period.  Actual results could differ from
      those estimates.

f)    RECLASSIFICATION  OF CAPITAL  ACCOUNTS:  Accounting  principles  generally
      accepted in the United States of America  require that certain  components
      of net assets relating to permanent  differences be  reclassified  between
      financial and tax reporting. These reclassifications have no effect on net
      assets or net  asset  value  per  share.  On  December  31,  2005 the Fund
      increased  undistributed  net  investment  income by  $658,171,  increased
      accumulated  net  realized  gain  on  investments  by $146  and  decreased
      additional paid-in capital by $658,317 due primarily to differing book/tax
      treatment of distributions and bond amortization.

3. FEES AND RELATED PARTY TRANSACTIONS

a) MANAGEMENT ARRANGEMENTS:

      Aquila   Investment   Management  LLC  (the  "Manager"),   a  wholly-owned
subsidiary of Aquila  Management  Corporation,  the Fund's  founder and sponsor,
serves  as the  Manager  for the  Fund  under  an  Advisory  and  Administration
Agreement with the Fund. The portfolio management of the



Fund has been delegated to a Sub-Adviser as described below.  Under the Advisory
and Administration  Agreement,  the Manager provides all administrative services
to the Fund, other than those relating to the day-to-day  portfolio  management.
The Manager's  services include providing the office of the Fund and all related
services as well as overseeing  the activities of the  Sub-Adviser  and managing
relationships with all the various support organizations to the Fund such as the
shareholder servicing agent, custodian,  legal counsel, auditors and distributor
and additionally  maintaining the Fund's  accounting books and records.  For its
services,  the Manager is entitled to receive a fee which is payable monthly and
computed as of the close of  business  each day at the annual rate of 0.50 of 1%
on the Fund's average net assets.

      Kirkpatrick  Pettis  Capital  Management,  Inc.  (the  "Sub-Adviser"),   a
wholly-owned  subsidiary  of the Davidson  Companies,  serves as the  Investment
Sub-Adviser for the Fund under a Sub-Advisory  Agreement between the Manager and
the Sub-Adviser.  Under this agreement,  the Sub-Adviser  continuously provides,
subject to oversight  of the Manager and the Board of Trustees of the Fund,  the
investment  program of the Fund and the  composition of its portfolio,  arranges

to receive a fee from the Manager  which is payable  monthly and  computed as of
the close of  business  each day at the annual  rate of 0.20 of 1% on the Fund's
average net assets.

      Under a Compliance  Agreement with the Manager, the Manager is compensated
for Chief  Compliance  Officer related  services  provided to enable the Fund to
comply with Rule 38a-1 of the Investment Company Act of 1940.

      Specific  details  as to the  effect  of the  Fund's  payments  under  its
Distribution  Plan, as described  below, on the above  management fees and as to
the  nature  and  extent  of the  services  provided  by  the  Manager  and  the
Sub-Adviser  are more fully  defined in the Fund's  Prospectus  and Statement of
Additional Information.

b) DISTRIBUTION AND SERVICE FEES:

      The Fund has adopted a  Distribution  Plan (the  "Plan")  pursuant to Rule
12b-1 (the "Rule") under the Investment  Company Act of 1940.  Under one part of
the Plan, with respect to Class A Shares, the Fund is authorized to make service
fee payments to broker-dealers or others  ("Qualified  Recipients")  selected by
Aquila Distributors,  Inc. (the "Distributor"),  including,  but not limited to,
any principal  underwriter of the Fund,  with which the  Distributor has entered
into  written  agreements  contemplated  by the Rule  and  which  have  rendered
assistance  in the  distribution  and/or  retention  of  the  Fund's  shares  or
servicing of  shareholder  accounts.  The Fund  currently  makes payment of this
distribution  fee at the  annual  rate of 0.05 of 1% of the Fund's  average  net
assets  represented  by Class A Shares.  The Board of Trustees and  shareholders
approved an  amendment to the Fund's  Distribution  Plan  applicable  to Class A
Shares which permits the Fund to make service fee payments at the rate



of up to 0.15 of 1% on the entire net assets  represented by Class A Shares. For
the six months ended June 30, 2006, distribution fees on Class A Shares amounted
to $53,430 of which the Distributor retained $1,736.

      Under  another part of the Plan,  the Fund is  authorized to make payments
with  respect to Class C Shares to  Qualified  Recipients  which  have  rendered
assistance in the distribution  and/or retention of the Fund's Class C shares or
servicing of shareholder accounts. These payments are made at the annual rate of
0.75% of the Fund's average net assets represented by Class C Shares and for the
six months  ended June 30,  2006,  amounted to  $47,006.  In  addition,  under a
Shareholder  Services  Plan, the Fund is authorized to make service fee payments
with respect to Class C Shares to Qualified  Recipients  for providing  personal
services and/or maintenance of shareholder accounts.  These payments are made at
the annual rate of 0.25 of 1% of the Fund's  average net assets  represented  by
Class C Shares and for the six months  ended June 30, 2006  amounted to $15,668.
The total of these  payments with respect to Class C Shares  amounted to $62,674
of which the Distributor retained $14,147.

      Specific  details  about the Plans are more  fully  defined  in the Fund's
Prospectus and Statement of Additional Information.

      Under a Distribution  Agreement,  the Distributor  serves as the exclusive
distributor of the Fund's shares. Through agreements between the Distributor and
various  broker-dealer  firms ("dealers"),  the Fund's shares are sold primarily
through the facilities of these dealers having offices within Colorado, with the
bulk of sales commissions inuring to such dealers. For the six months ended June
30, 2006,  total  commissions on sales of Class A Shares amounted to $137,789 of
which the Distributor received $25,436.

c) OTHER RELATED PARTY TRANSACTIONS:

      For the six months ended June 30, 2006, the Fund incurred $34,740 of legal
fees  allocable to Hollyer Brady Barrett & Hines LLP,  counsel to the Fund,  for
legal services in conjunction with the Fund's ongoing operations.  The Secretary
of the Fund is a Partner at that firm.

4. PURCHASES AND SALES OF SECURITIES

      During the six months ended June 30, 2006,  purchases  of  securities  and
proceeds from the sales of securities  aggregated  $9,528,419  and  $19,942,323,
respectively.

      At  June  30,  2006,  the  aggregate  tax  cost  for  all  securities  was
$223,752,469.  At June 30, 2006 the aggregate gross unrealized  appreciation for
all  securities  in which  there is an  excess  of  market  value  over tax cost
amounted to  $4,792,798  and aggregate  gross  unrealized  depreciation  for all
securities in which there is an excess of tax cost over market value amounted to
$1,124,009 for a net unrealized appreciation of $3,668,789.



5. PORTFOLIO ORIENTATION

      Since the Fund  invests  principally  and may  invest  entirely  in double
tax-free  municipal  obligations  of issuers within  Colorado,  it is subject to
possible risks  associated with economic,  political,  or legal  developments or
industrial  or regional  matters  specifically  affecting  Colorado and whatever
effects these may have upon Colorado issuers' ability to meet their obligations.

6. EXPENSES

      The Fund has negotiated an expense offset  arrangement  with its custodian
wherein it receives credit toward the reduction of custodian fees and other Fund
expenses  whenever  there  are  uninvested  cash  balances.   The  Statement  of
Operations  reflects the total expenses before any offset,  the amount of offset
and the net expenses.  It is the general intention of the Fund to invest, to the
extent  practicable,  its cash balances in  income-producing  assets rather than
leave cash uninvested.

7. CAPITAL SHARE TRANSACTIONS

      Transactions in Capital Shares of the Fund were as follows:

8. TRUSTEES' FEES AND EXPENSES

      At June 30, 2006 there were 7 Trustees,  one of which is  affiliated  with
the Manager and is not paid any fees. The total amount of Trustees'  service and
attendance  fees paid during the 6 months  ended June 30, 2006 was  $51,110,  to
cover carrying out their  responsibilities and attendance at regularly scheduled
quarterly Board Meetings and meetings of the Independent  Trustees held prior to
each quarterly Board Meeting.  When additional or special meetings are held, the
meeting fees are paid to those Trustees in  attendance.  Trustees are reimbursed
for  their  expenses  such as  travel,  accommodations  and  meals  incurred  in
connection  with  attendance  at  Board  Meetings  and  the  Annual  Meeting  of
Shareholders.  For the six months  ended  June 30,  2006,  such  meeting-related
expenses amounted to $17,486.

9. SECURITIES TRADED ON A WHEN-ISSUED BASIS

      The  Fund  may  purchase  or  sell  securities  on  a  when-issued  basis.
When-issued transactions arise when securities are purchased or sold by the Fund
with payment and delivery  taking place in the future in order to secure what is
considered  to be an  advantageous  price  and  yield to the Fund at the time of
entering  into the  transaction.  Beginning  on the date the Fund  enters into a
when-issued  transaction,  cash or other liquid  securities are segregated in an
amount equal to or greater than the amount of the when-issued transaction. These
transactions  are  subject to market  fluctuations  and their  current  value is
determined in the same manner as for other securities.

10. INCOME TAX INFORMATION AND DISTRIBUTIONS

      The Fund declares  dividends  daily from net  investment  income and makes
payments monthly in additional shares at the net asset value per share, in cash,
or in a combination of both, at the shareholder's  option.  Net realized capital
gains, if any, are distributed annually and are taxable.

      The  Fund  intends  to  maintain,  to the  maximum  extent  possible,  the
tax-exempt  status  of  interest  payments  received  from  portfolio  municipal
securities in order to allow dividends paid to shareholders  from net investment
income to be exempt from  regular  Federal and State of Colorado  income  taxes.
However,  due  to  the  distribution  levels  maintained  by the  Fund  and  the
differences  between  financial  statement  reporting  and  Federal  income  tax
reporting  requirements,  distributions  made by the Fund may not be the same as
the Fund's net  investment  income,  and/or net realized  securities  gains.  At
December 31,  2005,  the Fund had a capital  loss  carryover  of $245,339  which
expires on December 31, 2012.  This  carryover is available to offset future net
realized  gains on  securities  transactions  to the extent  provided for in the
Internal  Revenue Code. To the extent that this loss carryover is used to offset
future  realized  capital gains,  it is probable the gains so offset will not be
distributed.



      The tax character of distributions:

                                   2005           2004
                               -----------    -----------
      Net tax-exempt income    $ 9,394,426    $ 9,625,055

                               ===========    ===========

      As of December 31, 2005, the components of distributable earnings on a tax
basis were as follows:

      Unrealized appreciation         $ 8,530,102
      Accumulated net realized loss      (245,339)
                                      -----------
                                      $ 8,284,763
                                      ===========

      The difference between book basis and tax basis unrealized appreciation is
attributable primarily to premium/discount adjustments.

ANALYSIS OF EXPENSES (UNAUDITED)

      As a  shareholder  of the Fund,  you may  incur  two  types of costs:  (1)
transaction  costs,  including  front-end  sales charges with respect to Class A
shares or contingent  deferred  sales  charges  ("CDSC") with respect to Class C
shares; and (2) ongoing costs,  including  management fees;  distribution and/or
service  (12b-1) fees; and other Fund  expenses.  The table below is intended to
help you understand your ongoing costs (in dollars) of investing in the Fund and
to compare  these  costs with the ongoing  costs of  investing  in other  mutual
funds.

      The table below is based on an investment of $1,000 invested on January 1,
2006 and held for the six months ended June 30, 2006.

ACTUAL EXPENSES

      This table  provides  information  about actual  account values and actual
expenses.  You may use the information provided in this table, together with the
amount you invested,  to estimate the expenses that you paid over the period. To
estimate the expenses you paid on your account, divide your ending account value
by $1,000 (for example, an $8,600 ending account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During the Period".

FOR THE SIX MONTHS ENDED JUNE 30, 2006

ANALYSIS OF EXPENSES (UNAUDITED) (CONTINUED)

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

      The table below provides information about hypothetical account values and
hypothetical  expenses  based on the actual expense ratio and an assumed rate of
return of 5.00% per year before expenses, which is not the Fund's actual return.
The  hypothetical  account  values and  expenses may not be used to estimate the
actual ending account  balance or expenses you paid for the period.  You may use
the information provided in this table to compare the ongoing costs of investing
in the Fund and other mutual funds.  To do so,  compare this 5.00%  hypothetical
example relating to the Fund with the 5.00% hypothetical examples that appear in
the shareholder reports of other mutual funds.

      Please  note  that the  expenses  shown in the  table  below  are meant to
highlight  your ongoing  costs only and do not reflect any  transactional  costs
with respect to Class A shares.  The example  does not reflect the  deduction of
contingent  deferred  sales  charges  ("CDSC")  with  respect to Class C shares.
Therefore,  the table is useful in comparing  ongoing  costs only,  and will not
help you determine the relative total costs of owning different mutual funds. In
addition,  if these transaction costs were included,  your costs would have been
higher.

ADDITIONAL INFORMATION (UNAUDITED)

RENEWAL  OF THE  ADVISORY  AND  ADMINISTRATION  AGREEMENT  AND THE  SUB-ADVISORY
AGREEMENT

      Renewal until April 30, 2007 of the Advisory and Administration  Agreement
(the "Advisory Agreement") between the Fund and the Manager and the Sub-Advisory
Agreement (the  "Sub-Advisory  Agreement")  between the Manager and  Kirkpatrick
Pettis Capital Management, Inc. (the "Sub-Adviser") was approved by the Board of
Trustees and the  independent  Trustees in March,  2006. At a meeting called and
held for that  purpose  at which a majority  of the  independent  Trustees  were
present in person, the following materials were considered:

      o     Copies of the agreements to be renewed;

      o     A term sheet describing the material terms of the agreements;

      o     The Annual Report of the Fund for the year ended December 31, 2005;

      o     A report of the Manager containing data about the performance of the
            Fund,  data about its fees,  expenses and purchases and  redemptions
            together with comparisons of such data with similar data about other
            comparable  funds,  as well as data as to the  profitability  of the
            Manager and the Sub-Adviser; and

      o     Quarterly  materials  reviewed  at  prior  meetings  on  the  Fund's
            performance, operations, portfolio and compliance.

      The Trustees considered the Advisory and Administration  Agreement and the
Sub-Advisory  Agreement  separately as well as in conjunction with each other to
determine their combined  effects on the Fund. The Trustees  reviewed  materials
relevant  to,  and  considered,  the  factors  set forth  below,  and as to each
agreement reached the conclusions described.

THE NATURE,  EXTENT, AND QUALITY OF THE SERVICES PROVIDED BY THE MANAGER AND THE
SUB-ADVISER.

      The Manager has  provided  all  administrative  services to the Fund.  The
Board  considered  the  nature  and  extent  of  the  Manager's  supervision  of
third-party service providers,  including the Fund's shareholder servicing agent
and  custodian.  The Board  considered  that the  Manager  had  established  and
maintained a strong culture of ethical  conduct and regulatory  compliance,  and
had not been subject to the kinds of regulatory and legal difficulties affecting
a number of other investment advisers.

      The Manager has arranged for the  Sub-Adviser to provide local  management
of the Fund's  portfolio.  The Trustees noted that the Sub-Adviser  employed Mr.
Christopher  Johns  as  portfolio  manager  for the  Fund,  and had  established
facilities for credit analysis of the Fund's  portfolio  securities.  Mr. Johns,
based in Denver,  has provided local information  regarding specific holdings in
the Fund's  portfolio.  The portfolio manager has also been available to provide
the brokerage and financial planner  community with information  generally about
the  Fund's  portfolio,  with  which  that  community  can assess the Fund as an
investment  vehicle for  residents of Colorado in light of  prevailing  interest
rates and local economic conditions.

      The Board considered that the Manager and the Sub-Adviser had provided all
services  the Board  deemed  necessary or  appropriate,  including  the specific
services that the Board has determined are required for the Fund, given that its
purpose is to provide shareholders with as high a level of current income exempt
from  Colorado  state and regular  Federal  income taxes as is  consistent  with
preservation of capital. It noted that compared to other Colorado state-specific
municipal  bond funds,  the  portfolio of the Fund was of  significantly  higher
quality and contained no securities subject to the alternative minimum tax.

      The Board  concluded  that a commendable  quality of services was provided
and that the Fund would be well  served if they  continued.  Evaluation  of this
factor  weighed  in  favor  of  renewal  of  the  Advisory   Agreement  and  the
Sub-Advisory Agreement.



THE INVESTMENT PERFORMANCE OF THE FUND.

      The Board reviewed each aspect of the Fund's  performance and compared its
performance with that of its local  competitors and with national  averages.  It
was noted that the materials  provided by the Manager indicated that compared to
the five  largest  competitive  Colorado  funds,  the  Fund  has had  investment
performance  that is  somewhat  below  that of its  peers  for  one-,  five- and
ten-year  periods,  with lower rates of return explained by the Fund's generally
higher-quality portfolio and generally shorter average maturities.

      The Board  concluded  that the  performance  of the Fund,  in light of its
investment  objectives and market  conditions,  was satisfactory.  Evaluation of
this factor indicated to the Trustees that renewal of the Advisory Agreement and
Sub-Advisory Agreement would be appropriate.

THE COSTS OF THE  SERVICES  TO BE  PROVIDED  AND  PROFITS TO BE  REALIZED BY THE
MANAGER AND SUB-ADVISER AND AFFILIATES FROM THE RELATIONSHIP WITH THE FUND.

      The information provided in connection with renewal contained expense data
for the  Fund and its  local  competitors  as well as data for all  single-state
tax-free municipal bond funds nationwide,  including data for all such front-end
load  funds  of  a  comparable   asset  size.  The  materials  also  showed  the
profitability to the Manager and the Sub-Adviser of their services to the Fund.

      The Board  compared  the expense and fee data with  respect to the Fund to
similar data about other funds that it found to be relevant. The Board concluded
that  the  expenses  of the  Fund and the fees  paid  were  similar  to and were
reasonable as compared to those being paid by  single-state  tax-free  municipal
bond funds nationwide,  being less than the national average,  and by the Fund's
local competitors, all but one of which had higher fees.

      The Board considered that the foregoing  indicated the  appropriateness of
the costs of the services to the Fund, which was being well managed as indicated
by the factors considered previously.

      The Board further  concluded that the profitability to the Manager and the
Sub-Adviser  did not argue  against  approval  of the fees to be paid  under the
Advisory Agreement or the Sub-Advisory Agreement.

THE EXTENT TO WHICH ECONOMIES OF SCALE WOULD BE REALIZED AS THE FUND GROWS.

      Data  provided to the Trustees  showed that the Fund's asset size had been
relatively  steady in recent years.  However,  they concluded that the uncertain
interest rate environment might make it difficult to achieve  substantial growth
in assets  in the near  future.  The  Trustees  also  noted  that the  materials
indicate  that the Fund's  fees are  already  generally  lower than those of its
peers, including those with breakpoints.  Evaluation of this factor indicated to
the Board that the  Advisory  Agreement  and  Sub-Advisory  Agreement  should be
renewed without addition of breakpoints at this time.

BENEFITS  DERIVED OR TO BE  DERIVED BY THE  MANAGER  AND  SUB-ADVISER  AND THEIR
AFFILIATES FROM THEIR RELATIONSHIPS WITH THE FUND.

      The Board observed that, as is generally true of most fund complexes,  the
Manager and Sub-Adviser and their affiliates,  by providing services to a number
of funds or other  investment  clients  including the Fund,  were able to spread
costs as they would  otherwise  be unable to do. The Board noted that while that
produces   efficiencies  and  increased   profitability   for  the  Manager  and
Sub-Adviser and their affiliates,  it also makes their services available to the
Fund at favorable levels of quality and cost which are more  advantageous to the
Fund than would otherwise have been possible.

ITEM 2. CODE OF ETHICS.

		Not applicable.

ITEM 3.  AUDIT COMMITTEE FINANCIAL EXPERT.

(a)(1)(ii) The Board of Trustees of the Fund has determined that
it does not have at least one audit committee financial expert
serving on its audit committee.  The Fund does not have such a
person serving on the audit committee because none of the persons
currently serving as Trustees happens to have the technical
accounting and auditing expertise included in the definition of
"audit committee financial expert" recently adopted by the Securities
and Exchange Commission in connection with this Form N-CSR, and the
Board has not heretofore deemed it necessary to seek such a person
for election to the Board.

The primary mission of the Board, which is that of oversight over
the operations and affairs of the Fund, confronts the Trustees with
a wide and expanding range of issues and responsibilities. The
Trustees believe that, accordingly, it is essential that the Board's
membership consist of persons with as extensive experience as possible
in fulfilling the duties and responsibilities of mutual fund directors
and audit committee members and, ideally, with extensive experience
and background relating to the economic and financial sectors and
securities in which the Fund invests, including exposure to the
financial and accounting matters commonly encountered with respect
to those sectors and securities.  The Board believes that its current
membership satisfies those criteria.  It recognizes that it would
also be helpful to have a member with the relatively focused accounting
and auditing expertise reflected in the applicable definition of
"audit committee financial expert," just as additional members with
similarly focused technical expertise in other areas relevant to
the Fund's operations and affairs would also contribute added value.
However, the Board believes that the Fund is better served, and its
assets better employed, by a policy of hiring experts in various
the specialized area of technical accounting and
auditing matters, if and as the Board identifies the need, rather
than by seeking to expand its numbers by adding technical experts
in the areas constituting its domain of responsibility.  The Fund's
Audit Committee Charter explicitly authorizes the Committee to
retain such experts as it deems necessary in fulfilling its duties
under the Charter.


ITEM 4.  PRINCIPAL ACCOUNTANT FEES AND SERVICES

		Not applicable.

ITEM 5.  AUDIT COMMITTEE OF LISTED REGISTRANTS.
		Not applicable.

ITEM 6.  [RESERVED]

ITEM 7.  DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR
         CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

905:   	Not applicable.

ITEM 8. [RESERVED]

ITEM 9.  CONTROLS AND PROCEDURES.

(a)  Based on their evaluation of the registrant's disclosure controls and
procedures (as defined in Rule 30a-2(c) under the Investment Company Act of
1940) as of a date within 90 days of the fling of this report, the registrant's
chief financial and executive officers have concluded that the disclosure
controls and procedures of the registrant are appropriately designed to ensure
that information required to be disclosed in the registrant's reports that are

principal financial officer(s), to allow timely decisions regarding required
disclosure and is recorded, processed, summarized and reported, within the time
periods specified in the rules and forms adopted by the Securities and Exchange
Commission.

(b)  There have been no significant changes in registrant's internal controls or
in other factors that could significantly affect registrant's internal controls
subsequent to the date of the most recent evaluation, including no significant
deficiencies or material weaknesses that required corrective action.

ITEM 10.  EXHIBITS.

(a)(1) Aquila Group of Funds Code of Ethics for Principal Executive and
Senior Financial Officers under Section 406 of the Sarbanes-Oxley Act
