Narragansett Insured Tax-Free Income Fund
"How Your Fund is Coping
With the Current Market Situation"

                                                                  February, 2008

Dear Fellow Shareholder:

      As you are well aware,  our country has been going through a credit crunch
that began last year,  particularly in August,  2007. This credit  situation and
liquidity crisis have continued to worsen in various forms since that time which
has also led to a weakening in the U.S. dollar.

      While  things have  continued to be quite messy in the  securities  market
despite the actions of the Federal  Reserve to lower interest  rates, we feel it
is  important  for you to know that we are doing  everything  possible to ensure
that your investment in Narragansett  Insured Tax-Free Income Fund does not have
any problems.

      By design,  Narragansett Insured Tax-Free Income Fund consists entirely of
securities  which,  due to the  addition  of  insurance  bought  by  issuers  or
otherwise, are currently credit rated as AAA. You should be aware, however, that
when  purchasing  securities  for the Fund's  portfolio,  we always  look to the
underlying credit quality of the issues. Even without insurance and other credit
enhancements,  your Fund's  portfolio  manager has confirmed that the UNDERLYING
CREDIT QUALITY of the Fund's portfolio  holdings is approximately  76.6% A-rated
or higher.  Additionally,  the average  maturity of the securities in the Fund's
portfolio is intermediate in nature.  Thus, with a portfolio of high quality and
intermediate maturity securities, the Fund's share value has remained reasonably
stable.  We  strongly  believe  that when  things  get  tough in the  securities
markets, that's when a portfolio of high quality investments pays off.

      You can be assured  that we will seek to continue  operating  the Fund and
maintaining  its portfolio in your best interest.  As we have  emphasized to you
since the founding of  Narragansett  Insured  Tax-Free Income Fund, the Trustees
and management  team of your Fund fully realize that it is YOUR money,  invested
in YOUR Fund,  invested in projects  throughout YOUR  communities and state. Not
only are YOUR  investments  in the Fund being handled as well as we can in terms
of its portfolio construction, but your Fund is also helping to fund hundreds of
vital municipal projects throughout Rhode island.

      Because it is YOUR Fund,  we try to ensure  that all  shareholders  always
have the chance to know what is going on with their investment.  Furthermore, we
want  shareholders  to have the chance to ask any  questions  of the  management
team,  to  ease  any  concern  they  might  have.  Thus,  to  provide  you  with
face-to-face  access to your  management  team, we always hold  IN-STATE  Annual
Meetings of Shareholders.

                         NOT A PART OF THE ANNUAL REPORT



      One question asked during a recent shareholder  meeting of another fund in
the Aquila Group of Funds that we think you might find of interest concerned the
cost of running the fund.  This question  gives us an  opportunity  to emphasize
that the total annualized expense ratio of Narragansett  Insured Tax-Free Income
Fund  Class A shares  is 0.62%  (as you will  note in the  enclosed  Semi-Annual
Report).  Or, put another way, the total annual  operating  cost is only 0.62 of
1%. With the average expense ratio of similar type funds being 0.83%, we believe
that  Narragansett  Insured  Tax-Free  Income  Fund  is  doing  a  good  job  of
controlling costs.

      We appreciate your loyalty to Narragansett  Insured  Tax-Free Income Fund.
We will do everything we can to merit your continued trust.

                                   Sincerely,

                                [PHOTO OMITTED]

                    NARRAGANSETT INSURED TAX-FREE INCOME FUND
                          NOTES TO FINANCIAL STATEMENTS
                          DECEMBER 31, 2007 (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.

f)    ACCOUNTING   PRONOUNCEMENTS:   In  July  2006,  the  Financial  Accounting
      Standards Board ("FASB") released FASB  Interpretation  No. 48 "Accounting
      for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides  guidance for
      how uncertain tax positions should be recognized,  measured, presented and
      disclosed in the financial  statements.  FIN 48 requires the evaluation of
      tax positions taken or expected to be taken in the course of preparing the
      Fund's  tax  returns  to   determine   whether  the  tax   positions   are
      "more-likely-than-not" of being sustained by the applicable tax authority.
      Tax positions not deemed to meet the more-likely-than-not  threshold would
      be recorded as a tax  benefit or expense in the current  year.  FIN 48 was
      effective  for the Fund on December  31, 2007 and there were no  uncertain
      tax positions to be reflected in the Fund's financial statements.

      In  September  2006,  FASB issued  FASB  Statement  No.  157,  "Fair Value
      Measurement"  ("SFAS  157"),  which  defines  fair  value,  establishes  a
      framework for measuring  fair value,  and expands  disclosures  about fair
      value measurements. SFAS 157 is effective for fiscal years beginning after



      November 15, 2007, and interim periods within those fiscal years. The Fund
      believes  adoption of SFAS 157 will have no material  impact on the Fund's
      financial statements.

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 average 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, 2007,  the Fund incurred  management
fees of $380,400 of which  $266,280  was waived.  The Manager has  contractually
undertaken to waive fees and/or  reimburse Fund expenses  during the period July
1, 2007 through June 30, 2008 so that total Fund expenses would not exceed 0.85%
for Class A Shares,  1.70% for Class C Shares, 1.02% for Class I Shares or 0.70%
for Class Y Shares.

      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, 2007, distribution fees on Class A
Shares amounted to $76,732, of which the Distributor retained $1,849.

      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, 2007  amounted to $51,244.  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, 2007, amounted to $17,081.  The
total of these payments with respect to Class C Shares  amounted to $68,325,  of
which the Distributor retained $17,353.

      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,
2007,  these  payments were made at the average annual rate of 0.35% of such net
assets amounting to $1,421 of which $812 related to the Plan and $609 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 brokerage and advisory firms  ("intermediaries"),  the Fund's shares are
sold  primarily  through the facilities of these  intermediaries  having offices
within  Rhode  Island,  with  the  bulk of  sales  commissions  inuring  to such
intermediaries. For the six months ended December 31, 2007, total commissions on
sales of Class A Shares amounted to $88,027,  of which the Distributor  received
$7,976.

c) Other Related Party Transactions:

      For the six months ended December 31, 2007,  the Fund incurred  $56,688 of
legal fees  allocable to Butzel Long PC, counsel to the Fund, for legal services
in conjunction with the Fund's ongoing operations.  The Secretary of the Fund is
a shareholder in that firm.

4. PURCHASES AND SALES OF SECURITIES

      During the six months ended December 31, 2007, purchases of securities and
proceeds  from the sales of securities  aggregated  $3,827,030  and  $3,170,350,
respectively.

      At December  31,  2007,  the  aggregate  tax cost for all  securities  was
$147,399,106.  At December 31, 2007, the aggregate gross unrealized appreciation
for all  securities  in which there is an excess of value over tax cost amounted
to $3,908,832 and aggregate gross unrealized  depreciation for all securities in
which there is an excess of tax cost over value amounted to $138,626,  for a net
unrealized appreciation of $3,770,206.

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, 2007, 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,  2007,  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.

7. CAPITAL SHARE TRANSACTIONS

      Transactions in Capital Shares of the Fund were as follows:

8. TRUSTEES' FEES AND EXPENSES

      At December  31, 2007 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 six months  ended  December  31, 2007 was
$55,704,  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  meetings
(audit, nominating, and 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, 2007, such meeting-related expenses amounted to $19,926.

9. INCOME TAX INFORMATION AND DISTRIBUTIONS

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

      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  undistributed  net investment  income in the
amount of  $278,524  and  debited  additional  paid-in  capital in the amount of
$278,524 at June 30, 2007. This adjustment had no impact on the Fund's aggregate
net assests at June 30, 2007.  Further,  a small portion of the  dividends  may,
under some circumstances, be subject to taxes at ordinary income rates.

      At June 30,  2007,  the Fund had a capital  loss  carryover of $879,705 of
which $592,992 expires on June 30, 2009,  $111,495 expires on June 30, 2013, and
$175,218  expires on June 30, 2015. 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.  As of June 30, 2007 there were post-October capital loss deferrals
of $27,660 which will be recognized in the following year.



      Tax character of distributions:

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

      As of June 30, 2007,  the  components of  distributable  earnings on a tax
basis were as follows:

      Undistributed tax-exempt income         $   148,931
      Accumulated net realized loss              (879,705)
      Unrealized appreciation                   1,468,208
      Post-October capital loss deferrals         (27,660)
      Other temporary differences                (148,931)
                                              -----------
                                              $   560,843
                                              ===========

      At June  30,  2007,  the  difference  between  book  basis  and tax  basis
unrealized appreciation was attributable primarily to the treatment of accretion
of discounts and amortization of premiums.

10. RECENT DEVELOPMENTS

      In late May,  2007,  the U. S.  Supreme  Court agreed to hear an appeal in
DEPARTMENT   OF  REVENUE  OF   KENTUCKY  V.  DAVIS,   a  case   concerning   the
constitutionality  of differential  tax treatment for interest from in-state vs.
out-of-state municipal securities, a practice which is common among the majority
of the states.  If the U.S.  Supreme Court affirms the prior decision,  Kentucky
(and all other states that  differentially  tax interest on municipal bonds) may
then be required to accord equal  income tax  treatment  to all  municipal  bond
interest. While it is impossible to predict the consequences of such an outcome,
they may include  effects on the net asset  values of the shares,  and/or on the
tax  treatment of the  dividends,  of some or all  single-state  municipal  bond
funds,  including the Fund. The U.S. Supreme Court heard the case on November 5,
2007 and is expected to hand a decision down in 2008.

      Over the past few months,  municipal  bond  insurance  companies have been
under review by the three major rating agencies  Standard & Poor's,  Moody's and
Fitch.  The  ratings of some of the  insurance  companies  have now either  been
downgraded  and/or have a negative  outlook.  The financial  markets continue to
assess the severity of the losses  caused by the subprime  credit crisis and its
impact on municipal bond insurance companies and insured municipal bond prices.

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 July 1,
2007 and held for the six months ended December 31, 2007.

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".

      TOTAL RETURN IS NOT  ANNUALIZED,  AS IT MAY NOT BE  REPRESENTATIVE  OF THE
      TOTAL RETURN FOR THE YEAR.

(2)   EXPENSES ARE EQUAL TO THE ANNUALIZED EXPENSE RATIO OF 0.62%,  1.47%, 0.76%

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  December  31,  2008  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 RBS Citizens (the "Sub-Adviser")
was approved by the Board of Trustees and the independent  Trustees in December,
2007.  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, 2007

      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 of capital stock 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  co-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 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 Manager has additionally  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.

      The Board  concluded  that the  services  provided  were  appropriate  and
satisfactory  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 reviewed each aspect of the Fund's  performance and compared its
performance with that of its local competitors,  with national averages and with
the benchmark  index.  It was noted that the  materials  provided by the Manager
indicated that compared to the three  competitive Rhode Island funds, the Fund's
average  annual  total  return  outperformed  that of all of its three peers for
one-year  period and two of its three peers for the 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 SUB-ADVISER AND THEIR  AFFILIATES FROM THEIR  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 and 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.  Additionally, it was noted that the Manager had contractually
undertaken to waive fees and/or  reimburse Fund expenses  during the period July
1, 2007 through June 30, 2008 so that total Fund expenses  would not exceed 0.85
of 1% for Class A Shares,  1.70 of 1% for Class C Shares, 1.03 of 1% for Class I
Shares and 0.70 of 1% for Class Y Shares.  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  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  generally  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 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.
