                      "THE BENEFITS OF TAX-FREE INVESTING"

                                                                  February, 2006

Dear Fellow Shareholder:

      As the name of your fund clearly  states,  Narragansett  Insured  Tax-Free
Income Fund is  tax-free*  - free from Rhode  Island  state and regular  Federal
income taxes.

      This tax-free status serves many purposes.  It obviously provides you, and
our  other   shareholders,   with  tax-free   income.   But,  it  also  provides
municipalities  with  an  attractive  motivator  to  help  them  raise  revenue.
Additionally,  the  projects  funded by these  tax-free  securities  enhance the
quality of life for all community residents.

      Many  individuals pay as much as 30% to 40% of their income in Federal and
state taxes.  Obviously, if you have to pay that much in taxes, it significantly
reduces what you get to keep in your pocket.

BENEFITS TO INVESTORS

      As an  investor  seeking  tax-free  income,  do you have to forego  higher
yields? Not necessarily.

                                  [BAR CHART]

                  Hypothetical Tax-Free Yield                       3%
                  Hypothetical Taxable Equivalent Yield           5.2%

                  Hypothetical Tax-Free Yield                       4%
                  Hypothetical Taxable Equivalent Yield           6.9%

                  Hypothetical Tax-Free Yield                       5%
                  Hypothetical Taxable Equivalent Yield           8.8%

                        This chart assumes a 35% federal and 9% state tax-rate
                        and is for illustration purposes only; it does not
                        represent past or future performance of any investment.

      The chart above shows 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 you can  clearly  see from the chart,  you would have to earn 6.9% 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
Narragansett  Insured  Tax-Free Income Fund 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.

BENEFITS TO MUNICIPALITIES

      As you are most likely aware, states,  counties,  cities, towns, and other
forms of  municipalities  issue  tax-free  bonds to raise  monies.  These issues
generally take two forms - general obligation securities and revenue securities.

      General  obligation  municipal  securities are primarily those  securities
used to finance the general  needs of such  municipalities.  General  obligation
securities are secured by the tax-raising power of the specific  municipality in
terms of its ability to pay  interest  and repay  principal  on a timely  basis.
Thus,  these  securities  are  considered  to be  "backed  by the full faith and
credit" of the issuer.

      Revenue  securities  are issued to finance  specific  projects,  such as a
hospital  or  airport.  In this  instance,  the  municipal  issuer  pledges  the
operating  revenues  derived from the  specific  project to pay the interest and
repay the principal when due.

      In many cases, smaller  municipalities would have difficulty selling these
securities  to the  marketplace  were  it not for the  added  attractiveness  of
tax-free status.

BENEFITS TO QUALITY OF LIFE

      The benefit you may not have considered - when you made your investment in
the Fund - was that in the process of having the Fund provide you with  tax-free
income,  it also provides help to a variety of others within your  community and
Rhode Island. This is a benefit in which you can take real pride.

      Municipal  bonds,  such as those in which  Narragansett  Insured  Tax-Free
Income  Fund  invests,   are  the  primary  way   infrastructure   is  financed.
Infrastructure is a relatively  obscure word that by itself doesn't mean much to
most people.  But, when you translate  the word  "infrastructure"  into projects
such as schools, roads, bridges, water facilities,  pollution control, airports,
hospitals,  and fire and police  stations,  then you are  speaking in terms that
people more easily understand.

      As the  economy  of  Rhode  Island  grows,  new and  additional  municipal
projects  are needed for the  benefit of the  citizens  of Rhode  Island and the
various communities throughout the state. In essence, your money invested in the
Fund  helps  pay for that new  school,  road,  airport,  etc.  that you and your
neighbors now enjoy. So, as an investor in Narragansett  Insured Tax-Free Income
Fund, you can take pride in knowing that you are playing a vital role and a very
real part in enhancing the quality of life for your family,  friends,  neighbors
and future generations of Rhode Islanders.

SUMMARY

      So the next time that you receive your statement from Narragansett Insured
Tax-Free  Income  Fund,  remember  that the  benefits  that are reaped from your
investment are more than just what is evident on that piece of paper.

Sincerely,


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

                    NARRAGANSETT INSURED TAX-FREE INCOME FUND
                          NOTES TO FINANCIAL STATEMENTS
                          DECEMBER 31, 2005 (UNAUDITED)

1. ORGANIZATION

      Narragansett Insured Tax-Free Income Fund (the "Fund"), a non-diversified,
open-end   investment   company,   was  organized  on  January  22,  1992  as  a
Massachusetts business trust and commenced operations on September 10, 1992. The
Fund is authorized to issue 80,000,000 shares and, since its inception to May 1,
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 October 31, 1997, 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 fee and
a service fee. All classes of shares  represent  interests in the same portfolio
of  investments  and are identical as to rights and  privileges  and 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 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 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.

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,  fund accounting agent, auditor and
distributor. 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% on the Fund's net assets.

      Citizens  Investment  Advisors,  a  department  of Citizens  Bank of Rhode
Island (the  "Sub-Adviser")  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 for the purchases and sales
of portfolio securities, and provides for daily pricing of the Fund's portfolio.
For its services,  the Sub-Adviser is entitled 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 0.23% on the Fund's average net assets.

      For the six months ended December 31, 2005,  the Fund incurred  management
fees of $389,232 of which  $280,247  was  voluntarily  waived.  Such waivers are
voluntary  and can be  terminated  in the  future at the  Manager's  discretion.
However,  the Manager has indicated that it intends to continue  waiving fees as
necessary in order that the Fund will remain competitive.



      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 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
distribution 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 makes payment of this service fee at
the annual rate of 0.15% of the Fund's average net assets represented by Class A
Shares. For the six months ended December 31, 2005, distribution fees on Class A
Shares amounted to $78,881, of which the Distributor retained $2,040.

      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  December 31, 2005  amounted to $70,317.  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 the Fund's average net assets represented by Class C
Shares and for the six months ended December 31, 2005, amounted to $23,439.  The
total of these payments with respect to Class C Shares  amounted to $93,756,  of
which the Distributor retained $23,582.

      Under  another part of the Plan,  the Fund is  authorized to make payments
with respect to Class I Shares to Qualified Recipients.  Class I payments, under
the Plan,  may not  exceed,  for any fiscal  year of the Fund a rate  (currently
0.20%) set from time to time by the Board of  Trustees of not more than 0.25% of
the average annual net assets  represented  by the Class I Shares.  In addition,
the Fund has a  Shareholder  Services  Plan under which it may pay service  fees
(currently 0.15%) of not more than 0.25% of the average annual net assets of the
Fund represented by Class I Shares. That is, the total payments under both plans
will not exceed 0.50% of such net assets.  For the six months ended December 31,
2005,  these  payments were made at the average annual rate of 0.20% of such net
assets  amounting to $2,055 of which $1,173 related to the Plan and $881 related
to the Shareholder Services Plan.

      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 Rhode Island,  with the bulk of sales commissions inuring to such
dealers.  For the six months ended December 31, 2005, total commissions on sales
of Class A Shares  amounted  to  $109,131,  of which  the  Distributor  received
$10,571.

c) OTHER RELATED PARTY TRANSACTIONS:

      For the six months ended December 31, 2005,  the Fund incurred  $56,621 of
legal fees  allocable to Hollyer Brady Barrett & Hines LLP,  counsel to the Fund
for legal fees in conjunction with the Fund's ongoing operations.  The Secretary
of the Fund is a partner in that firm.

4. PURCHASES AND SALES OF SECURITIES

      During the six months ended December 31, 2005, purchases of securities and
proceeds  from the sales of securities  aggregated  $9,726,912  and  $4,323,240,
respectively.

      At December  31,  2005,  the  aggregate  tax cost for all  securities  was
$149,737,972.  At December 31, 2005, the aggregate gross unrealized appreciation
for all  securities  in which  there is an excess of market  value over tax cost
amounted to  $4,651,954  and aggregate  gross  unrealized  depreciation  for all
securities in which there is an excess of tax cost over market value amounted to
$262,215, for a net unrealized appreciation of $4,389,739.

5. PORTFOLIO ORIENTATION

      Since the Fund  invests  principally  and may  invest  entirely  in double
tax-free municipal  obligations of issuers within Rhode Island, it is subject to
possible risks  associated with economic,  political,  or legal  developments or
industrial or regional matters specifically  affecting Rhode Island and whatever
effects  these  may have  upon  Rhode  Island  issuers'  ability  to meet  their
obligations.  However,  to mitigate  against such risks,  the Fund has chosen to
have at least 80% and  possibly  the  entire  number of issues in the  portfolio
insured as to timely  payment of principal  and interest  when due by nationally
prominent municipal bond insurance  companies.  At December 31, 2005, all of the
securities  in the Fund were  insured.  While such  insurance  protects  against
credit risks with portfolio  securities,  it does not insure against market risk
of fluctuations in the Fund's share price and income return.

      The  Fund is also  permitted  to  invest  in  U.S.  territorial  municipal
obligations  meeting  comparable quality standards and providing income which is
exempt from both regular  Federal and Rhode  Island  income  taxes.  The general
policy  of the  Fund  is to  invest  in such  securities  only  when  comparable
securities of Rhode Island issuers are not available in the market.  At December
31, 2005, the Fund had all of its net assets invested in Rhode Island  municipal
issues.

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,  some or all of cash  balances in  income-producing  assets
rather than leave cash on deposit.

      Transactions in Capital Shares of the Fund were as follows:

8. TRUSTEES' FEES AND EXPENSES

      At December  31, 2005 there were 8  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 six months  ended  December  31, 2005 was
$75,775,  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 at the Annual  Meeting of  Shareholders.  For the six months
ended December 31, 2005, such meeting-related expenses amounted to $10,284.

9. 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 Rhode Island income taxes.
However,  due to 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.
In this regard,  the Fund  credited  distributions  in excess of net  investment
income in the amount of $131,004 and debited  additional  paid-in capital in the
amount of $131,004 at June 30, 2005. This adjustment had no impact on the Fund's
aggregate  net  assests  at June  30,  2005.  Further,  a small  portion  of the
dividends may, under some circumstances,  be subject to taxes at ordinary income
rates.

      At June 30,  2005,  the Fund had a capital  loss  carryover of $743,647 of
which  $632,152  expires on June 30, 2009 and $111,495 which expires on June 30,
2013.  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 is used to offset future realized capital gains, it
is probable the gains so offset will not be distributed.

      Tax character of distributions:

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

      As of June 30, 2005,  the  components of  distributable  earnings on a tax
basis were as follows:

      Accumulated net realized loss                           $  (743,647)
      Unrealized appreciation                                   7,264,099
                                                              -----------
                                                              $ 6,520,452
                                                              ===========

      At June  30,  2005,  the  difference  between  book  basis  and tax  basis
unrealized appreciation was attributable primarily to the treatment of accretion
of discounts and amortization of premiums.

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 tables below are 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 tables below are based on an investment of $1,000  invested on July 1,
2005 and held for the six months ended December 31, 2005.

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".

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)

NARRAGANSETT INSURED TAX-FREE INCOME FUND (THE "FUND"):

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

Renewal  until  December 31, 2006 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  Citizens
Investment  Advisors,  a  department  of  Citizens  Bank of  Rhode  Island  (the
"Sub-Adviser")  was  approved  by the  Board  of  Trustees  and the  independent
Trustees in  December,  2005.  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 June 30, 2005;

      o     A report,  prepared by the Manager and  provided to the  Trustees in
            advance of the meeting for the  Trustees'  review,  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  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 and Sub-Adviser  have provided local  management of the Fund's
portfolio. The Trustees noted that the Sub-Adviser employed Salvatore C. DiSanto
and  Jeffrey  K.  Hanna as  portfolio  managers  for the  Fund and had  provided
facilities  for credit  analysis  of the Fund's  portfolio  securities.  Messrs.
DiSanto  and  Hanna,  based  in  Providence,  have  provided  local  information
regarding specific holdings in the Fund's portfolio. The portfolio managers have
also been  available to and have met with the brokerage  and  financial  planner
community  and with  investors  and  prospective  investors to provide them with
information generally about the Fund's portfolio,  with which to assess the Fund
as an  investment  vehicle for  residents of Rhode Island in light of prevailing
interest rates and local economic conditions.  In addition,  one or both of them
have been present at all regular meetings of the Board and Shareholders.

      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 Rhode  Island
state and regular  Federal income taxes as is consistent  with  preservation  of
capital. It noted that compared to other Rhode Island  state-specific  municipal
bond funds, the portfolio of the Fund was of significantly  higher quality,  was
the only fund in the state  with 100% of its  portfolio  instruments  insured or
pre-refunded,  and contained no securities  subject to the  alternative  minimum
tax.

      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  recently affecting a
significant number of other investment advisers.

      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 MANAGER AND SUB-ADVISER.

      The Board  determined it appropriate  to consider the Fund's  performance.
For the one,  five and  ten-year  periods  ended  September  30, 2005 the Fund's
average  annual  rate of return for Class A Shares  was 2.20%,  5.48% and 5.29%,
respectively. Performance for the other classes was similar.

      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  three   competitive  Rhode  Island  funds,  the  Fund  has  had  investment
performance that is comparable to that of two of its three peers for one-, five-
and  ten-year  periods,  with lower  rates of return  compared to the third peer
explained by the Fund's generally higher-quality portfolio and generally shorter
average maturities. The Board considered these results to be consistent with the
purposes of the Fund.

      The Board  concluded that the  performance of the Fund, in light of 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 ITS AFFILIATES AND THE SUB-ADVISER 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 insured  single-state
funds, 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 noted that both the Manager and  Sub-Adviser  were currently
waiving  a  portion  of their  respective  fees and had been  since  the  Fund's
inception.  For the year ended June 30, 2005, the Fund incurred  management fees
of $753,282,  of which $579,069 was voluntarily waived.  While such waivers were
voluntary and could be terminated in the future,  the Manager had indicated that
it intended to continue  waiving  fees as necessary in order that the Fund would
remain competitive.



      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 generally  lower than those
being paid by single-state tax-free municipal bond funds nationwide,  and by the
Fund's local competitors.

      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,
Sub-Adviser and the Distributor 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
generally increasing in recent years. The Trustees also noted that the materials
indicated  that the  Fund's  fees were  already  lower  than those of its peers,
including those with breakpoints. Additionally, the Trustees noted that both the
Manager and Sub-Adviser  were currently  waiving a substantial  portion of their
respective  fees.  Evaluation of these  factors  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.
