                           RANSON MANAGED PORTFOLIOS

                          THE OKLAHOMA MUNICIPAL FUND

                                 1 NORTH MAIN
                           MINOT, NORTH DAKOTA 58703

                                (800) 601-5593

     The Oklahoma Municipal Fund is an investment portfolio of Ranson Managed
Portfolios which is an unincorporated business trust organized under the laws of
Massachusetts on August 10, 1990.  Ranson Managed Portfolios is an open-end
series non-diversified management company, known as a mutual fund.  The term
"the Fund" as used herein shall refer to either Ranson Managed Portfolios or The
Oklahoma Municipal Fund series of Ranson Managed Portfolios as the context may
require.  The investment objective of the Fund is to provide its shareholders
with as high a level of current income exempt from both federal income tax and,
to the extent indicated, Oklahoma income tax, as is consistent with preservation
of capital.  UP TO 30% OF THE FUND'S TOTAL ASSETS MAY BE INVESTED IN OKLAHOMA
MUNICIPAL SECURITIES (AS DEFINED HEREIN) WHICH ARE SUBJECT TO OKLAHOMA STATE
INCOME TAXES.  Under normal market conditions, the Fund's assets will be
invested in a portfolio of Oklahoma Municipal Securities which, in the opinion
of Ranson Capital Corporation, will produce a higher level of current income
than would be produced by a portfolio of Oklahoma Municipal Securities rated in
only the highest rating category, but contains Oklahoma Municipal Securities
which do not present a significant risk of loss of principal due to credit
characteristics.  In pursuit of this objective, the Fund invests primarily in
debt obligations issued by or on behalf of the State of Oklahoma, its political
subdivisions and their agencies and instrumentalities.  A substantial portion of
the income produced by the Fund may be includable in the calculation of
alternative minimum taxable income.  Shares of the Fund therefore would not
ordinarily be a suitable investment for investors who are subject to the
alternative minimum tax.

     A maximum sales load of 4.25% will be imposed on purchases (4.44% of the
net amount invested).  The minimum initial investment is $1,000.  See "Purchase
of Shares."

     Ranson Capital Corporation (the "Manager") is the Fund's manager.  ND
Resources, Inc. serves as the Fund's Transfer Agent and First Western Bank &
Trust serves as the Fund's Custodian.

     THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED
UPON THE ACCURACY OR ADEQUACY
<PAGE>
 
OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

     SHARES OF THE FUND ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
ENDORSED BY, ANY BANK AND ARE NOT FEDERALLY INSURED BY THE FEDERAL DEPOSIT
INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD, OR ANY OTHER AGENCY.

     READ AND RETAIN THIS PROSPECTUS FOR FUTURE REFERENCE.  THE PROSPECTUS
CONCISELY SETS FORTH INFORMATION INVESTORS SHOULD KNOW BEFORE INVESTING IN THE
FUND.

     A Statement of Additional Information, dated the date of this Prospectus,
regarding the Fund (which is incorporated herein by reference) has been filed
with the Securities and Exchange Commission and is available upon request and
without charge by writing the Fund at the above mailing address or by
telephoning the Manager at either of the numbers set forth above.

                             FEE AND EXPENSE TABLE

     The following tables set forth (i) the non-recurring shareholder
transaction expenses, (ii) the recurring annual Fund operating expenses and
(iii) the estimated expenses paid directly and indirectly by a shareholder with
a hypothetical $1,000 investment that is subject to the maximum sales load over
1 and 3 year periods.

     The following example should not be considered a representation of past or
future expenses.  Actual expenses may be greater or lesser than those shown.

Shareholder would pay the following
  expenses after fee waiver on a $1,000

</TABLE>

     The purpose of these tables is to assist the investor in understanding the
various costs and expenses that an investor in the Fund will bear directly or
indirectly.  The calculation presumes expenses for the current year at the
projected rate of .85% for the Fund after a partial fee waiver by the Manager.
Management Fees, Rule 12b-1 Fees, Other Expenses and Total Fund Operating
Expenses for the Fund are estimated to be 0.50%, 0.25%, 0.40% and 1.15% before
fee waiver.  These expense estimates assume a voluntary waiver by the Manager of
a portion of its fee not required by the Management and Investment Advisory
Agreement.  These costs and expenses should not be considered a representation
of past or future expenses, and the actual expenses incurred by the Fund, and
the degree of expense reimbursement and fee waiver, if any, may be greater or
less in the future.  See "Purchase of Shares" for information relating to sales
load discounts and "Fund Management" for the level of management fees and "The
Distributor" for information relating to the Fund's Shareholder Services Plan.
Long-term shareholders may pay more than the economic equivalent of the maximum
front-end sales charge permitted by the National Association of Securities
Dealers, Inc.

                 HIGHLIGHTS OF THE FUND AND PROSPECTUS SUMMARY

     The highlights and summary information below should be read in conjunction
with the detailed information appearing elsewhere in this Prospectus.

     The Investment Objective of the Fund is to provide its shareholders with as
high a level of current income that is exempt from both federal income tax and,
to the extent indicated, Oklahoma income tax as is consistent with preservation
of capital.  Under normal market conditions, the Fund's assets will be invested
in a portfolio of Oklahoma Municipal Securities which, in the opinion of Ranson
Capital Corporation, will produce a higher level of current income than would be
produced by a portfolio of Oklahoma Municipal Securities rated in only the
highest rating category, but contains Oklahoma Municipal Securities which do not
present a significant risk of loss of principal due to credit characteristics.
There is no assurance that the Fund's investment objective will be achieved.
See "Investment Objective and Policies--Investment Objective."

     The Investment Policy of the Fund is to invest in a portfolio of investment
grade municipal securities which generate interest income that is exempt from
both federal income tax and Oklahoma income tax, to the extent indicated.  These
municipal securities (hereinafter referred to as "Oklahoma Municipal
Securities") generally include debt

                                      -3-
<PAGE>
 
obligations of the State of Oklahoma, its political subdivisions,
municipalities, agencies and authorities, and certain industrial development and
other revenue bonds, short-term municipal notes, participation interests in
municipal leases and tax-exempt commercial paper issued by such entities. Up to
30% of the Fund's total assets may be invested in Oklahoma Municipal Securities
which are subject to Oklahoma state income taxes. See "Investment Objective and
Policies--Oklahoma Municipal Securities" for a more complete description of
Oklahoma Municipal Securities. In certain circumstances the Fund may enter into
when-issued or delayed delivery transactions and purchase taxable securities.
The Fund may, for hedging purposes, enter into financial futures contracts,
options on such futures, municipal bond index futures contracts and options on
securities. These investments entail certain risks. See "Investment Objective
and Policies--Futures Contracts and Options."  The interest on certain Oklahoma
Municipal Securities in the Fund's portfolio may constitute an item of
preference for determining the federal alternative minimum tax for individuals
and corporations. See "Dividends and Taxes."

     The Fund's Shares May Be Purchased through Ranson Capital Corporation and
selected dealers at the public offering price, which is equal to the net asset
value next determined, plus a sales charge of 4.25% of the public offering price
(4.44% of the net amount invested).  See "Purchase of Shares."

     The Minimum Initial Investment is $1,000 and the minimum additional
investment is  $100.  See "Purchase of Shares."  The initial and minimum
investments will be less under certain conditions described under "Purchase of
Shares" and "Special Programs."

     An Open Account Program will be established for each investor unless the
investor elects not to participate in such program as is provided under
"Purchase of Shares"--Open Account Program/Certificates."

     Special Programs of the Fund include: a group program; a systematic
withdrawal program; a preauthorized investment program; a rights of accumulation
program; and a reinstatement privilege.  See "Special Programs."

     The Fund has a Shareholder Services Plan adopted pursuant to Rule 12b-1
under the Investment Company Act of 1940, pursuant to which .25% per annum of
average daily net assets will be used to pay dealers and banks selling Fund
shares for administrative and shareholder services or to pay for certain
distribution expenses.  See "The Distributor."

     Distributions for the Fund will be declared daily from net investment
income and will be paid monthly; net capital gains, if any, will be distributed
at least annually.  See "Dividends and Taxes."

     Confirmation Statements will be sent to all investors who have had purchase
or redemption activity in their account.

                                      -4-
<PAGE>
 
     REDEMPTIONS can be made at net asset value, without charge.  The Fund may
require redemption of shares if the value of an account is reduced to $1,000 or
less (for any reason other than fluctuations in the market value of the Fund's
portfolio securities).  See "Redemption of Shares."

     THE FUND'S MANAGER AND INVESTMENT ADVISER is Ranson Capital Corporation
which receives a monthly management and investment advisory fee equivalent on an
annual basis to .50 of 1% of the Fund's average daily net assets.  Under the
terms of the Management and Investment Advisory Agreement between the Fund and
the Manager, the Manager pays all expenses of the Fund, including the Fund's
management and investment advisory fee and the Fund's dividend disbursing,
administrative and accounting services fees (but excluding taxes and brokerage
fees and commissions, if any) that exceed 1.25% of the Fund's average daily net
assets on an annual basis up to the amount of the management and investment
advisory fee payable by the Fund to the Manager.  The Manager may assume
additional Fund expenses or waive portions of its fees in its discretion.  See
"Fund Management." Ranson Capital Corporation will act as the Fund's Evaluator.
The procedures of the Evaluator and its valuations are reviewed by the officers
of the Fund under the general supervision of the Board of Trustees.  See "Net
Asset Value."

     RISK FACTORS:  The Fund is subject to the risks of primarily concentrating
its investments in Oklahoma Municipal Securities and does not have the benefit
of geographical investment diversification (see "Investment Objective and
Policies").  Also, as a non-diversified investment company, the Fund has the
ability to concentrate investments in particular issuers which may be
advantageous when investing in Oklahoma Municipal Securities, but which involves
an increased risk of loss to the Fund should an issuer be unable to make
interest or principal payments or should the market value of such securities
decline.  The Fund has the ability to purchase new issues of Oklahoma Municipal
Securities on a "when-issued" basis as well as outstanding issues on a delayed
delivery basis, both of which involve the potential risk of loss of principal in
the event either that the value of such securities to be purchased declines
prior to the settlement date or if such securities should ultimately not be
issued or delivered and the price of comparable securities has increased, the
cost of substitute securities having comparable par amounts, ratings and yields
will be greater than was originally contracted for.  A substantial portion of
the Oklahoma Municipal Securities in the Fund's portfolio may derive their
payment from mortgage loans, utilities, turnpikes or from hospitals and other
health care facilities, all of which entail certain risks (see "Investment
Objective and Policies--Oklahoma Municipal Securities").  The Fund may from
time to time invest in participations in municipal leases.  Municipal leases are
less liquid than many other municipal securities and therefore will be subject
to the risks of illiquidity referred to in the next paragraph.  Also, municipal
leases are subject to the risk of "non-appropriation" which allows the municipal
lessee to terminate the lease and eliminate its obligation to continue to make
lease payments (see "Investment Objective and Policies--Oklahoma Municipal
Securities").

     The Fund will invest a substantial portion of its assets in investment
grade Oklahoma Municipal Securities.  Lower quality securities involve a greater
risk of default, including nonpayment of principal and interest, than investment
grade securities; however, the risk of

                                      -5-
<PAGE>
 
default is present in investment grade securities. Oklahoma Municipal Securities
rated in the lowest category of investment grade debt may have speculative
characteristics. Investment in medium-quality debt securities (rated BBB or A by
Standard & Poor's Corporation or Baa or A by Moody's Investors Service, Inc.)
involves greater investment risk, including the possibility of issuer default or
bankruptcy, than investment in higher-quality debt securities. An economic
downturn could severely disrupt this market and adversely affect the value of
outstanding bonds and the ability of the issuers to repay principal and
interest. During a period of adverse economic changes, including a period of
rising interest rates, issuers of such bonds are more likely to experience
difficulty in servicing their principal and interest payment obligations than is
the case with higher grade bonds. In addition, an investment in the Fund should
be made with an understanding that the value of the underlying portfolio may
decline with increases in interest rates. In recent years there have been wide
fluctuations in interest rates and thus in the value of fixed-rate, long-term
debt obligations generally. The Manager cannot predict whether these
fluctuations will continue in the future. The principal trading market for the
Oklahoma Municipal Securities will generally be in the over-the-counter market.
As a result, the existence of a liquid trading market for the Oklahoma Municipal
Securities may depend on whether dealers will make a market in such securities.
There can be no assurance that a market will be made for any of the Oklahoma
Municipal Securities, that any market for the Oklahoma Municipal Securities will
be maintained or of the liquidity of the Oklahoma Municipal Securities in any
markets made. In addition, certain of the Oklahoma Municipal Securities may be
subject to extraordinary optional and/or mandatory redemptions at par if certain
events should occur. To the extent securities were purchased at a price in
excess of the par value thereof and are subsequently redeemed at par as a result
of an extraordinary redemption, the Fund would suffer a loss of principal.

     The Fund may invest in financial futures contracts and related options
thereon for hedging purposes.  A risk in employing futures contracts to protect
against the price volatility of portfolio securities is that the prices of
securities subject to futures contracts may not correlate perfectly with the
behavior of the cash prices of the Fund's portfolio securities.  The risk of
imperfect correlation may be increased by the fact that the Fund may trade in
futures contracts on taxable securities and there is no guarantee that the
prices of taxable securities will move in a manner similar to the prices of tax-
exempt securities.  Another risk is that the Manager could be incorrect in its
expectations as to the direction or extent of various interest rate movements or
the time span within which the movements take place.  For example, if the Fund
sold futures contracts in anticipation of an increase in interest rates, and
then interest rates went down, causing bond prices to rise, the Fund would lose
money and incur transaction costs on the sale.

                                   THE FUND

     Ranson Managed Portfolios is an unincorporated business trust organized
under the laws of Massachusetts on August 10, 1990.  It is an open-end non-
diversified series management investment company or "mutual fund."  The Oklahoma
Municipal Fund is one of four portfolios or "series" offered at this time.  Like
other mutual funds, the Fund sells its shares to investors and uses the proceeds
to invest in various securities as described in this Prospectus.  The Fund is
subject to the overall direction and monitoring function of the Board of
Trustees (the "Trustees").

     Information regarding the Fund is available by telephoning or writing the
Fund at the phone number or address shown on the front cover of this Prospectus.

                       INVESTMENT OBJECTIVE AND POLICIES

INVESTMENT OBJECTIVE

     The investment objective of the Fund is to provide its shareholders with as
high a level of current income exempt from both federal income tax and, to the
extent indicated, Oklahoma income tax as is consistent with preservation of
capital.  Under normal market conditions, the Fund's assets will be invested in
a portfolio of Oklahoma Municipal Securities which, in the opinion of Ranson
Capital Corporation, will produce a higher level of current income than would be
produced by a portfolio of Oklahoma Municipal Securities rated in only the
highest rating category, but contains Oklahoma Municipal Securities which do not
present a significant risk of loss of principal due to credit characteristics.
The Fund seeks to achieve its investment objective by investing primarily in
Oklahoma Municipal Securities (as further described below).  At the respective
times of issuance of the Oklahoma Municipal Securities, certain, but not
necessarily all, of the issues of the Oklahoma Municipal Securities may have
been accompanied by an opinion of bond counsel to the respecting issuing
authorities that interest on such Oklahoma Municipal Securities are exempt from
Oklahoma income tax.  The Fund may invest up to 30% of its total assets in
Oklahoma Municipal Securities, the interest on which is subject to Oklahoma
income tax.  Oklahoma law provides that to the extent dividends paid by the Fund
are derived from Oklahoma Municipal Securities, they shall be exempt from
Oklahoma income tax.

     A shareholder will receive taxable income in the event of capital gains
distributions by the Fund.  In addition, the Fund has not established any limit
on the percentage of its portfolio that may be invested in Oklahoma Municipal
Securities subject to the alternative minimum tax provisions of federal tax law,
and a substantial portion of the income produced by the Fund may be includable
in the calculation of alternative minimum taxable income.  Shares of the Fund
therefore would not ordinarily be a suitable investment for investors who are
subject to the alternative minimum tax.  The suitability of shares of the Fund
for these investors will depend upon a comparison of the yield likely to be
provided from the Fund with the yield from comparable tax-exempt investments not
subject to the alternative

                                      -7-
<PAGE>
 
minimum tax, and with the yield from comparable fully taxable investments, in
light of each such investor's tax position.

OKLAHOMA MUNICIPAL SECURITIES

     As used in this Prospectus, the term "Oklahoma Municipal Securities" refers
to debt obligations of Oklahoma, its political subdivisions, municipalities,
agencies and authorities the interest payable on which is, in the opinion of
bond counsel to the issuer, exempt from federal income taxation.  The Fund will
not invest more than 30% of its total assets in Oklahoma Municipal Securities,
the interest on which is subject to Oklahoma income tax.  The term "Oklahoma
Municipal Securities" also includes obligations of the Commonwealth of Puerto
Rico, the Virgin Islands and Guam, the interest payable on which is, in the
opinion of bond counsel to the issuer, exempt from federal income taxation.  The
Fund will not invest more than 30% of its total assets in Oklahoma Municipal
Securities which are obligations of the Commonwealth of Puerto Rico, the Virgin
Islands or Guam.  Oklahoma Municipal Securities include debt obligations of
Oklahoma, its political subdivisions, municipalities, agencies and authorities
issued to obtain funds for various public purposes, including the construction
or improvement of a wide range of public facilities such as airports, bridges,
highways, hospitals, housing, jails, mass transportation, nursing homes, parks,
public buildings, recreational facilities, school facilities, streets and water
and sewer works.  Other public purposes for which Oklahoma Municipal Securities
may be issued include the refunding of outstanding obligations, the anticipation
of taxes or state aids, the payment of judgments, the funding of student loans,
community redevelopment, the purchase of street maintenance and firefighting
equipment, or any authorized corporate purpose of the issuer except for the
payment of current expenses.  In addition, certain types of industrial
development and other revenue bonds may be issued by or on behalf of public
corporations to finance privately operated housing facilities, air or water
pollution control facilities and certain local facilities for water supply, gas,
electricity or sewage or solid waste disposal.  Other types of industrial
development bonds, the proceeds of which are used for the construction,
equipping, repair or improvement of privately operated industrial, commercial or
office facilities, constitute Oklahoma Municipal Securities, although current
federal income tax laws place substantial limitations on the size of such
issues.

     Since the Fund will invest substantially all of its assets in Oklahoma
Municipal Securities, the Fund is susceptible to political and economic factors
affecting the issuers of Oklahoma Municipal Securities.  Investors in the Fund
should consider that the economy of Oklahoma has been experiencing difficulties
as a result of an economic recession largely attributable to a decline in the
agricultural industry and a rapid decline that was experienced in the early and
mid 1980s in the energy industry which have, in turn, caused declines in the
real estate industry, the banking industry and most other sectors of the State's
economy.  Continued low levels of economic activity, another decline in oil and
gas production prices, low growth in the State's major industries or private or
public financial difficulties could adversely affect Oklahoma Municipal
Securities in the portfolio of the Fund and consequently the value of a
shareholder's investment in the Fund.

                                      -8-

     Governmental expense budgeting provisions in Oklahoma are conservative,
basically requiring a balanced budget each fiscal year unless a debt is approved
by a vote of the people providing for the collection of a direct annual tax to
pay the debt.  Certain limited exceptions include: deficiency certificates
issued in the discretion of the Governor (however, the deficiency certificates
may not exceed $500,000 in any fiscal year) and debts to repel invasion,
suppress insurrection or to defend the State in the event of war.

     To ensure a balanced annual budget, the State Constitution provides
procedures for certification by the State Board of Equalization of revenues
received in the previous fiscal year and amounts available for appropriation
based on a determination of revenues to be received by the State in the General
Revenue Fund in the next ensuing fiscal year.

     Beginning July 1, 1985, surplus funds were to be placed in a Constitutional
Reserve Fund until the Reserve Fund equals 10% of the General Revenue Fund, as
certification for the preceding fiscal year.

     The foregoing information constitutes only a brief summary of some of the
financial difficulties which may impact certain issuers of Oklahoma Municipal
Securities and does not purport to be a complete or exhaustive description of
all adverse conditions to which the issuers in the Fund are subject.
Additionally, many factors including national economic, social and environmental
policies and conditions, which are not within the control of the issuers of
Oklahoma Municipal Securities, could affect or could have an adverse impact on
the financial condition of the State and its various agencies and political
subdivisions.  The Manager is unable to predict whether or to what extent such
factors or other factors may affect the issuers of Oklahoma Municipal
Securities, the market value or marketability of the Oklahoma Municipal
Securities or the ability of the respective issuers of the Oklahoma Municipal
Securities acquired by the Fund to pay interest on or principal of the Oklahoma
Municipal Securities.

     The Fund has a fundamental investment restriction which prohibits it from
investing more than 25% of its total assets in securities of issuers in any
single industry.  This restriction does not, however, place any such limitation
on the purchase of securities issued or guaranteed by the U.S. Government, its
agencies or instrumentalities or by Oklahoma, its political subdivisions,
municipalities, agencies and authorities.

     Over 25% of the Oklahoma Municipal Securities in the Fund's portfolio may
derive their payment from mortgage loans.  Such Oklahoma Municipal Securities
are single family mortgage revenue bonds issued for the purpose of acquiring
from originating financial institutions notes secured by mortgages on residences
located within the issuer's boundaries and owned by persons of low or moderate
income.  Mortgage loans are generally partially or completely prepaid prior to
their final maturities, as a result of events such as the sale of the mortgaged
premises, default condemnation or casualty loss.  Because these bonds are
subject to extraordinary mandatory redemption, in whole or in part, from such
prepayments on mortgage loans, a substantial portion of such bonds will probably
be redeemed prior to their scheduled maturities or even prior to their ordinary
call dates.  Extraordinary mandatory redemption without premium could also
result from the failure of the originating

                                      -9-
<PAGE>
 
financial institutions to make mortgage loans in sufficient amounts within a
specified time period or, in some cases, from the sale by the Bond issuer of the
mortgage loans. These bonds were issued under Section 103A of the Internal
Revenue Code, which Section contains certain ongoing requirements relating to
the use of the proceeds of such bonds in order for the interest on such bonds to
retain its tax-exempt status. In each case the issuer of the bonds has
covenanted to comply with applicable requirements and bond counsel to such
issuer has issued an opinion that the interest on the bonds is exempt from
federal income tax under existing laws and regulations. There can be no
assurance that such ongoing requirements will be met.

     Over 25% of the Oklahoma Municipal Securities in the Fund's portfolio may
be health care revenue bonds.  Ratings of bonds issued for health care
facilities are often based on feasibility studies that contain projections of
occupancy levels, revenues and expenses.  A facility's gross receipts and net
income available for debt service may be affected by future events and
conditions including, among other things, demand for services, the ability of
the facility to provide the services required, physicians' confidence in the
facility, management capabilities, competition with other hospitals, efforts by
insurers and governmental agencies to limit rates, legislation establishing
state rate-setting agencies, expenses, government regulation, the cost and
possible unavailability of malpractice insurance and the termination or
restriction of governmental financial assistance, including that associated with
Medicare, Medicaid and other similar third party payor programs.  Medicare
reimbursements are currently calculated on a prospective basis utilizing a
single nationwide schedule of rates.  Prior to this nationwide approach,
Medicare reimbursements were based on the actual costs incurred by the health
facility.  The current legislation may adversely affect reimbursements to
hospitals and other facilities for services provided under the Medicare program.

     The Oklahoma Municipal Securities in which the Fund invests consist of
Oklahoma bonds, notes, commercial paper and participation interests in municipal
leases.  Oklahoma tax-exempt notes and commercial paper are generally used to
provide for short-term capital needs and ordinarily have a maturity of up to one
year.  These include notes issued in anticipation of tax revenue, revenue from
other government sources or revenue from bond offerings and short-term,
unsecured commercial paper, which is often used to finance seasonal working
capital needs or to provide interim construction financing.  Oklahoma tax-exempt
leases are obligations of state and local government units incurred to lease or
purchase equipment or other property utilized by such governments.  The Fund
will not originate leases as a lessor, but will instead purchase a participation
interest in the regular payment stream of the underlying lease from a bank,
equipment lessor or other third party.  General obligation bonds are secured by
the issuer's pledge of its faith, credit and taxing power for the payment of
principal and interest.  Revenue bonds are payable from the revenue derived from
a particular facility or class of facilities or, in some cases, from the
proceeds of a special excise or other specific revenue source, but not from the
general taxing power.  Tax-exempt industrial development bonds are in most cases
revenue bonds and generally do not carry the pledge of the credit of the issuing
municipality.  The revenues from which such bonds are paid generally constitute
an obligation of the corporate entity on whose behalf the bonds are issued.

                                     -10-
<PAGE>
 
     Although the participations in municipal leases which the Fund may purchase
(hereinafter called "lease obligations") do not constitute general obligations
of the municipality for which the municipality's taxing power is pledged, a
lease obligation is ordinarily backed by the municipality's covenant to budget
for, appropriate and make the payments due under the lease obligation. However,
certain lease obligations contain "non-appropriation" clauses which provide that
the municipality has no obligation to make lease payments in future years unless
money is appropriated for such purpose on a yearly basis. In addition to the
"nonappropriation" risk, these securities represent a relatively new type of
financing that has not yet developed the depth of marketability associated with
more conventional bonds. Although "non-appropriation" lease obligations are
secured by the leased property, disposition of the property in the event of
foreclosure might prove difficult. The Fund will only purchase lease obligations
which are rated in the top category by either Standard & Poor's Corporation or
Moody's Investor Service, Inc. The Fund will not invest more than 15% of its net
investment assets in lease obligations (including, but not limited to those
lease obligations which contain "non-appropriation clauses"), or any other
illiquid securities.

     The Fund will only purchase lease obligations which are covered by an
existing opinion of legal counsel experienced in municipal lease transactions
that, as of the date of issue or purchase of each participation interest in a
municipal lease, the interest payable on such obligation is exempt from both
federal income tax and Oklahoma income tax and that the underlying lease was the
valid and binding obligation of the governmental issuer.

Investment Policies

     It is a fundamental policy of the Fund, which may not be changed without
the approval of the majority of the Fund's shares, that under normal
circumstances at least 70% of the Fund's assets will be invested in Oklahoma
Municipal Securities which generate income that is exempt, in the opinion of
bond counsel, from both federal income tax and Oklahoma income tax. While the
Fund attempts, under normal market conditions, to invest all of its assets in
Oklahoma Municipal Securities, the Fund may temporarily invest up to 100% of its
assets in taxable fixed-income securities or hold up to 100% of its assets in
cash during periods of abnormal market conditions that dictate taking a
defensive posture by investing in such taxable obligations or cash. In addition,
pending the investment or reinvestment in Oklahoma Municipal Securities of
proceeds of sales of shares or sales of portfolio securities or in order to
avoid the necessity of liquidating portfolio investments to meet shareholders'
redemption requests, the Fund may invest up to 20% of its assets in taxable
fixed income securities or cash.

     The Oklahoma Municipal Securities in which the Fund invests consist of
securities rated within the following grades assigned by Moody's Investors
Service, Inc. ("Moody's"): Aaa, Aa, A and Baa for bonds; MIG-1 and MIG-2 for
notes; Prime-1 and Prime-2 for commercial paper; or Standard & Poor's
Corporation ("S&P"): AAA, AA, A and BBB for bonds; SP-1 and SP-2 for notes; A-1
or A-2 for commercial paper. The risk of default, including nonpayment of
principal and interest, on securities rated below the three highest grades is
somewhat higher than the risk of default on securities rated within the three
highest 

                                     -11-
<PAGE>
 
grades. The Fund may also invest in Oklahoma tax-exempt industrial development
bonds, if the securities, at the time of purchase, are rated investment grade
quality by either Moody's or S&P. While ratings at the time of purchase will
determine which Oklahoma Municipal Securities may be acquired by the Fund, a
subsequent reduction in rating will not require the Fund to dispose of the
securities. The Fund will purchase unrated Oklahoma Municipal Securities which
have been determined to be of investment grade quality at the time of purchase
by the Fund's Manager pursuant to guidelines established and maintained in good
faith by the Board of Trustees of the Fund. Many issuers of tax-exempt
securities which have characteristics of rated securities choose not to have
their obligations rated. Although securities which are not rated are not
necessarily of lower quality, the market for them may not be as broad as for
rated securities, since many investors rely on rating agencies for credit
appraisal. As a fundamental policy, the Fund may not invest more than 30% of its
assets in unrated Oklahoma Municipal Securities. Also, the Fund will not invest
more than 15% of the Fund's net assets in lease obligations, or in any other
illiquid securities.

     Taxable obligations which the Fund may purchase for temporary liquidity
purposes, or for temporary defensive purposes, may include: obligations of the
U.S. Government, its agencies or instrumentalities; other debt securities of
issuers having, at the time of purchase, a rating within the four highest grades
of Moody's or S & P; commercial paper rated P-I or better by Moody's or A-1 or
better by S & P; certificates of deposit of domestic banks, including foreign
branches of domestic banks, which have capital, surplus and undivided profits of
over $100 million; time deposits; bankers' acceptances, repurchase agreements
and obligations of Oklahoma with respect to any of the foregoing investments.
Interest earned from taxable obligations will be taxable to investors.

     The Fund also may purchase floating and variable rate demand notes from
municipal and nongovernmental issuers. These notes normally have a stated
maturity in excess of one year, but permit the holder to demand payment of
principal plus accrued interest upon a specified number of days notice.
Frequently, such obligations are secured by letters of credit or other credit
support arrangements provided by banks. Use of letters of credit or other credit
support arrangements will generally not adversely affect the tax-exempt status
of these obligations. The Manager will rely upon the opinion of the issuer's
bond counsel to determine whether such notes are exempt from federal and
Oklahoma income taxation. The issuer of floating and variable rate demand notes
nominally has a corresponding right, after a given period, to prepay in its
discretion the outstanding principal amount of the note plus accrued interest
upon a specified number of days notice to the noteholders. The interest rate on
a floating rate demand note is based on a known lending rate, such as a bank's
prime rate, and is adjusted automatically each time such rate is adjusted. The
interest rate on a variable rate demand note is adjusted at specified intervals,
based upon a known lending rate. The Manager will monitor the creditworthiness
of the issuers of floating and variable rate demand notes. The Fund will not
invest in derivative financial instruments other than in connection with its
hedging activities.

     The yields on Oklahoma Municipal Securities are dependent on a variety of
factors, including general money market conditions, the financial condition of
the issuer, general conditions of the Oklahoma municipal obligations market, the
size of a particular offering,

                                     -12-
<PAGE>
 
the maturity of the obligation and the rating of the issue or issuer. The
ratings of Moody's and S&P represent their opinions as to the quality of the
Oklahoma Municipal Securities which they undertake to rate. It should be
emphasized, however, that ratings are general, and not absolute, standards of
quality. Consequently, Oklahoma Municipal Securities of the same maturity,
interest rate and rating may have different yields, while Oklahoma Municipal
Securities of the same maturity and interest rate with different ratings may
have the same yield. Subsequent to their purchase by the Fund, particular
Oklahoma Municipal Securities or other investments may cease to be rated or
their ratings may be reduced below the minimum rating required for purchase by
the Fund.

     Medium-quality Oklahoma Municipal Securities (rated BBB or A by S&P or Baa
or A by Moody's) are obligations of issuers that are considered to possess
adequate, but not outstanding, capacities to service the obligations. Oklahoma
Municipal Securities rated in the lowest category of investment grade debt
(rated BBB by S&P or Baa by Moody's) may have speculative characteristics.
Because many issuers of medium-quality Municipal Securities choose not to have
their obligations rated by a rating agency, up to 30% of the Oklahoma Municipal
Securities in the Fund's portfolio may be unrated. Investment in medium-quality
debt securities involves greater investment risk, including the possibility of
issuer default or bankruptcy, than investment in higher-quality debt securities.
An economic downturn could severely disrupt this market and adversely affect the
value of outstanding bonds and the ability of the issuers to repay principal and
interest. During a period of adverse economic changes, including a period of
rising interest rates, issuers of such bonds are more likely to experience
difficulty in servicing their principal and interest payment obligations than is
the case with higher grade bonds. Medium quality debt securities tend to be less
marketable than higher-quality debt securities because the market for them is
less broad. The market for unrated debt securities is even narrower. During
periods of thin trading in these markets, the spread between bid and asked
prices is likely to increase significantly, and the Fund may have greater
difficulty selling the medium-quality debt securities in its portfolio.

     The Fund is a non-diversified investment company, but intends to comply
with Subchapter M of the Internal Revenue Code. Because of the relatively small
number of issuers of investment grade Oklahoma Municipal Securities, the Fund
will probably use its ability as a non-diversified fund to concentrate its
assets in the securities of certain issuers which the Fund's Manager deems to be
attractive investments, rather than invest in securities of a large number of
issuers merely to satisfy diversification requirements. Although the Fund's
Manager believes that the ability to concentrate the investments of the Fund in
particular issuers is advantageous when investing in Oklahoma Municipal
Securities, such concentration involves an increased risk of loss to the Fund
should the issuer be unable to make interest or principal payments or should the
market value of such securities decline. Investment in a non-diversified
investment company such as the Fund may therefore entail greater risks than
investment in a "diversified" fund.

     The Fund may invest up to 10% of its total assets in the securities of
other investment companies. Any investment by the Fund in securities issued by
other investment companies will result in the duplication of certain fees and
expenses.

                                      -13-
<PAGE>
 
Futures Contracts and Options

     The Fund may invest in financial futures contracts ("futures contracts")
and related options thereon for hedging purposes. It is not the intent of the
Manager to speculate in futures contracts and related options as an aggressive
investment strategy, but rather as described below. The Fund may sell a futures
contract or a call option thereon or purchase a put option on such futures
contract if the Manager anticipates that interest rates will rise, as a hedge
against a decrease in the value of the Fund's portfolio securities. If the
Manager anticipates that interest rates will decline, the Fund may purchase a
futures contract or a call option thereon or sell a put option on such futures
contract to protect against an increase in the price of the securities the Fund
intends to purchase. These futures contracts and related options thereon will be
used only as a hedge against anticipated interest rate changes. A futures
contract sale creates an obligation by the Fund, as seller, to deliver the
specific type of instrument called for in the contract at a specified future
time for a specified price. Purchase of a futures contract creates an obligation
by the Fund, as purchaser, to take delivery of the specific type of financial
instrument at a specified future time at a specified price. A purchaser or
seller of a futures contract is required to make daily payments of cash to
reflect the change in the value of the underlying contract. The specific
securities delivered or taken, respectively, at settlement date would not be
determined until or near that date. The determination would be in accordance
with the rules of the exchange on which the futures contract sale or purchase
was effected.

     Although the terms of futures contracts specify actual delivery or receipt
of securities, in most instances the contracts are closed out before the
settlement date without the making or taking of delivery of the securities.
Closing out of a futures contract is effected by entering into an offsetting
purchase or sale transaction prior to the expiration of the contract.

     Unlike a futures contract, which requires the parties to buy and sell a
security on a set date unless offset, an option on a futures contract entitles
its purchaser to decide on or before a future date whether to enter into such a
contract (a long position in the case of a call option and a short position in
the case of a put option). If the purchaser decides not to enter into the
contract, the premium paid for the option on the contract is lost if it expires.
Since the cost of the option is fixed, there are no daily payments of cash by
the purchaser to reflect the change in the value of the underlying contract as
there are by a purchaser or seller of a futures contract. The seller of the
option, however, may be required to make daily maintenance margin payments to
reflect the change in value of the underlying contract. The value of the option
is reflected in the net asset value of the Fund.

     A risk in employing futures contracts to protect against the price
volatility of portfolio securities is that the prices of securities subject to
futures contracts may not correlate perfectly with the behavior of the cash
prices of the Fund's portfolio securities. The risk of imperfect correlation may
be increased by the fact that the Fund may trade in futures contracts on taxable
securities and there is no guarantee that the prices of taxable securities will
move in a manner similar to the prices of tax-exempt securities. The correlation
may be distorted in part by the fact that the futures market is influenced by

                                     -14-
<PAGE>
 
short-term traders seeking to profit from the difference between a contract or
security price objective and their cost of borrowed funds. Such distortions
generally are minor and should diminish as the contract approaches maturity.

     Another risk is that the Manager could be incorrect in its expectations as
to the direction or extent of various interest rate movements or the time span
within which the movements take place. For example, if the Fund sold futures
contracts in anticipation of an increase in interest rates, and then interest
rates went down, causing bond prices to rise, the Fund would lose money,
including transaction costs, on the sale.

     The Fund may not enter into futures contracts or purchase related options
thereon if immediately thereafter the amount committed to initial margin plus
the amount paid for premiums for unexpired options on futures contracts exceed
5% of the value of the Fund's total assets. Similarly, the Fund may not purchase
or sell futures contracts or related options thereon if, immediately thereafter,
more than one-third of its net assets would be hedged.

Forward Commitments

     The Fund may purchase new issues of Oklahoma Municipal Securities and other
securities on a "when-issued" or delayed delivery basis, with delivery and
payment for the securities normally taking place within 45 days after the date
of the commitment to purchase. The payment obligation and the interest rate that
will be received on such securities are fixed at the time the buyer enters into
the commitment. The Fund may enter into such "forward commitments" if it holds,
and maintains until the settlement date in a segregated account with its
custodian, cash or high-grade, short-term obligations in an amount sufficient to
meet the purchase price. There is no percentage limitation on the Fund's total
assets which may be invested in forward commitments. Forward commitments involve
a risk of loss if the value of the Oklahoma Municipal Security or other security
to be purchased declines prior to the settlement date, which risk is in addition
to the risk of decline in the value of the Fund's other assets. Although the
Fund will generally enter into forward commitments with the intention of
acquiring Oklahoma Municipal Securities or other securities for its portfolio,
the Fund may dispose of a commitment prior to settlement if the Manager deems it
appropriate to do so. The Fund may realize short-term profits or losses upon the
sale of forward commitments, which profits or losses may constitute capital
gains or ordinary income depending upon a number of factors, including the
number of sales of such commitments.

Portfolio Turnover

     Portfolio transactions will be undertaken principally to accomplish the
Fund's objective in relation to anticipated movements in the general level of
interest rates, but the Fund may also engage in short-term trading consistent
with its objective. Securities may be sold in anticipation of a market decline
(a rise in interest rates) or purchased in anticipation of a market rise (a
decline in interest rates) and later sold. In addition, a security may be sold
and another purchased at approximately the same time to take advantage of what
the
                                     -15-
<PAGE>
 
Manager believes to be a temporary disparity in the normal yield relationship
between the two securities. Yield disparities may occur for reasons not directly
related to the investment quality of particular issues or the general movement
of interest rates, due to such factors as changes in the overall demand for or
supply of various types of Oklahoma Municipal Securities or changes in the
investment objectives of investors.

     The Fund's investment policies may lead to frequent changes in investments,
particularly in periods of rapidly fluctuating interest rates. A change in
securities held by the Fund is known as "portfolio turnover" and may involve the
payment by the Fund of dealer mark-ups or underwriting commissions, and other
transaction costs, on the sale of securities, including Oklahoma Municipal
Securities, as well as on the reinvestment of the proceeds in other securities.
The Fund anticipates that its annual portfolio turnover rate will not exceed
75%. Portfolio turnover rate for a fiscal year is the ratio of the lesser of the
dollar amount of the purchases or sales of portfolio securities to the monthly
average of the value of portfolio securities excluding securities whose
maturities at acquisition were one year or less. The Fund's portfolio turnover
rate will not be a limiting factor when the Fund deems it desirable to sell or
purchase securities. Frequent changes in the Fund's portfolio securities may
result in higher transaction costs for the Fund. In addition, in order to
qualify as a regulated investment company under the Internal Revenue Code, the
Fund must limit the portion of its gross income derived from the sale or other
disposition of stock or securities held for less than three months. If the Fund
were unable to satisfy this condition, among others, the Fund would be subject
to tax on its taxable income without deduction for distributions to
shareholders. See "Dividends and Taxes" in this Prospectus and "Portfolio
Transactions" in the Fund's Statement of Additional Information.

Repurchase Agreements

     The Fund may enter into repurchase agreements with respect to not more than
10% of its total assets (taken at current value), except when investing for
temporary defensive purposes during times of adverse market conditions. A
repurchase agreement is a contract under which the Fund would acquire a security
for a relatively short period and the seller would agree to repurchase such
security at the Fund's cost plus interest within a specified time (generally one
day). Under the Investment Company Act of 1940, repurchase agreements are
considered loans by the Fund. The Fund will not enter into any repurchase
agreement in an amount which would jeopardize the Fund's status as a regulated
investment company or its ability to distribute tax-exempt dividends. Although
the Fund may enter into repurchase agreements with respect to any securities
which it may acquire consistent with its investment policies and restrictions,
it is the Fund's present intention to enter into repurchase agreements only with
respect to obligations of the U.S. Government or its agencies or
instrumentalities and with respect to Oklahoma Municipal Securities. The Fund's
custodian will hold the securities underlying any repurchase agreement in a
segregated account. In investing in repurchase agreements, the Fund's risk is
limited to the ability of the seller to pay the agreed-upon price at the
maturity of the repurchase agreement. In the opinion of the Manager, the risk is
not material, since in the event of default, barring extraordinary
circumstances, the Fund would be entitled to sell the underlying securities or
otherwise receive adequate protection under federal bankruptcy laws for its
interest in such securities.
                                     -16-
<PAGE>
 
To the extent that proceeds from any sale upon a default are less than the
repurchase price, however, the Fund could suffer a loss. In addition, the Fund
may incur certain delays in obtaining direct ownership of the collateral.

     The Fund's Board of Trustees may change any of the foregoing policies that
are not fundamental without an affirmative vote of a "majority of the Fund's
outstanding voting shares," as defined in "Investment Objective, Policies and
Restrictions" in the Fund's Statement of Additional Information.

                                NET ASSET VALUE

     The net asset value per share of the Fund is determined by calculating the
total value of the Funds' assets, deducting total liabilities, and dividing the
result by the number of shares outstanding. Fixed income securities are valued
at the mean between the quoted bid and asked price. Securities for which
quotations are not readily available (which will constitute a majority of the
securities held by the Fund) are valued at fair value as determined by Ranson
Capital Corporation (the "Evaluator") pursuant to procedures adopted by the
Board of Trustees using methods which include consideration of the following:
yields or prices of municipal bonds of comparable quality, type of issue,
coupon, maturity and rating, indications as to value from dealers and general
market conditions. The Evaluator may employ electronic data processing
techniques and/or a matrix system to determine valuations. The procedures
utilized by the Evaluator and its valuations are reviewed by the officers of the
Fund under the general supervision of the Board of Trustees and are periodically
reviewed by the Board of Trustees. Short-term securities with remaining
maturities of less than 60 days are valued at amortized cost. Other assets are
valued at fair value as determined in good faith by the Trustees of the Fund.
The net asset value of the Fund is computed once daily as of 3:15 p.m. Central
time on each day that the New York Stock Exchange is open for trading. The
public offering price based thereon becomes effective as of the time of such
computation. The New York Stock Exchange is closed on weekends and on the
following days: New Year's Day, Washington's Birthday, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund
reserves the right to calculate the net asset value and to adjust the public
offering price based thereon more frequently than once each day if deemed
desirable.

                              PURCHASE OF SHARES

     Shares may be purchased at the public offering price through any securities
dealer having a sales agreement with Ranson Capital Corporation (the
"Distributor"). Shares may also be purchased through banks and certain other
financial institutions that have agency agreements with the Distributor. These
financial institutions will receive transaction fees that are the same as
commissions to dealers and may charge their customers service fees relating to
investments in the Fund. Purchase requests should be addressed to the dealer or
agent from which this Prospectus was received which has a sales agreement with
the Distributor. Such dealer or agent may place a telephone order with the
Transfer Agent for the purchase of Fund shares. It is a dealer's or broker's
responsibility to promptly forward

                                      -17-
<PAGE>
 
payment and registration instructions (or completed applications) to the
Transfer Agent for shares being purchased. Reference should be made to the wire
order to ensure proper settlement of the trade. Payment must be received within
three business days of the order or the trade may be cancelled and the dealer or
broker placing the trade will be liable for any losses. The public offering
price is the net asset value per share next determined plus a sales charge that
will be a percentage of the public offering price and will vary as shown below.
Current sales charge rates are:

     The minimum initial investment is $1,000 and there is a $100 minimum on all
additional investments (excluding reinvestment of dividends and capital gains).
The Fund reserves the right to redeem Fund accounts that are reduced to a value
of less than $1,000 (for any reason other than fluctuation in the market value
of the Fund's portfolio securities). Should the Fund elect to exercise this
right, the investor will be notified before such redemption is processed that
the value of the investor's account is less than $1,000 and that the investor
will have sixty days to increase the account to at least the $1,000 minimum
amount before the account is redeemed.

     Shares of the Fund may be sold at net asset value to the officers and
Trustees of the Fund and to any employees of Ranson Capital Corporation or to
members of their immediate families. Immediate family members shall include
spouse, children, father, mother, brothers or sisters. Shares of the Fund may
also be sold at their net asset value to broker-dealers having sales agreements
with Ranson Capital Corporation and registered representatives and other
employees of such broker-dealers, including their spouses and children; to
financial institutions having sales agreements with Ranson Capital Corporation
and employees of such financial institutions, including their spouses and
children; and to any broker-dealer, financial institution, or other qualified
firm which receives no commissions for selling shares to its clients.

     From time to time the Distributor may implement programs under which
dealers and their representatives may be eligible to participate in which such
firms may win nominal awards for certain sales efforts or under which the
Distributor will reallow additional concessions to any dealer that sponsors
sales contests or recognition programs conforming to criteria established by the
Distributor or participates in sales programs sponsored by the Distributor.
These programs will not change the price that an investor pays for shares or

                                     -18-
<PAGE>
 
the amount that the Fund will receive from such sale. In addition, the Fund and
the Distributor may pay firms that sell the Fund's shares an annual service fee
for administrative and shareholder services, as described under "The
Distributor."

Letters of Intent

     An investor may qualify for a reduced sales charge immediately by stating
his or her intention to invest in one or more series of the Fund, during a 
13-month period, an amount that would qualify for a reduced sales charge and by
signing a nonbinding Letter of Intent which may be signed at any time within 90
days after the first investment to be included under the Letter of Intent. After
signing the Letter of Intent, each investment made by an investor will be
entitled to the sales charge applicable to the total investment indicated in the
Letter of Intent. If an investor does not complete the purchases under the
Letter of Intent within the 13-month period, the sales charge will be adjusted
upward, corresponding to the amount actually purchased. When an investor signs a
Letter of Intent, shares of a series of the Fund with a value of up to 5% of the
amount specified in the Letter of Intent will be restricted. If the total
purchases made by an investor under the Letter of Intent, less redemptions,
equals or exceeds the amount specified in the Letter of Intent, the restriction
on the shares will be removed. In addition, if the total purchases exceed the
amount specified and qualify for a further quantity discount, the Distributor
will make a retroactive price adjustment and will apply the adjustment to
purchase additional shares at the then current applicable offering price. If an
investor does not complete purchases under a Letter of Intent, the sales charge
is adjusted upward, and if after written notice to the investor, he or she does
not pay the increased sales charge, sufficient restricted shares will be
redeemed at the current net asset value to pay such charge. In connection with
the determination of sales charges applicable to the purchase of shares of the
Fund, the Letter of Intent program will take into account investments in shares
of any other mutual fund carrying a sales load of which Ranson Capital
Corporation is the Distributor.

Concurrent Purchases

     An investor or his or her dealer or agent must notify the Transfer Agent
whenever a quantity discount is applicable to purchases. Upon such notification,
an investor will receive the lowest applicable sales charge. Quantity discounts
may be modified or terminated by the Distributor at any time. For more
information about quantity discounts, contact the dealer or agent from which
this Prospectus was obtained or the Distributor.

Open Account Program/Certificates

     All investors in the Fund will be enrolled in an Open Account Program when
they make their first investment in the Fund, unless they elect otherwise.
Investors may then make additional purchases whenever they wish, but they are
not obligated to make any additional investments. Whenever investors make an
investment in the Fund, full and fractional shares will be purchased for their
account at the next determined public offering price applicable to their
purchase after the Fund receives their order.

                                     -19-
<PAGE>
 
     If an investor elects not to be enrolled in the Open Account Program by
notifying the Transfer Agent in written form, he or she will be sent share
certificates representing the full shares of the Fund and will be required to
surrender the certificates to redeem such shares. Fund share certificates will
be mailed within 10 days of an investor's request. Certificates will not be sent
outside of the United States. Investors should promptly notify the Fund if
certificates are not received. The Fund will not file a mail loss claim later
than one year after the issuance of Fund share certificates. After one year,
investors requesting replacement certificates may be required to post an
insurance bond in the amount of 2% of the market value of the certificated
shares.

                               SPECIAL PROGRAMS

Redemptions From Other Funds

     Shares of the Fund may be purchased at net asset value where the amount
invested is documented to the Fund to be proceeds from the redemption of shares
of mutual funds which do not impose a contingent deferred sales charge or
redemption fee and where the investor paid an initial sales charge. Purchases
must be made within 60 days of redemption date. The Fund reserves the right to
modify or terminate this privilege at any time without notice.

Group Program

     The Fund has a group investment and reinvestment program (the "Group
Program") which allows investors to purchase shares of a Series of the Fund with
a lower minimum initial investment and with a lower sales charge if the investor
and the Group Program of which he or she is a participant meet the cost saving
criteria set forth below.

     Description of Group Program.  If the investor's Group Program (such as an
employee investment program) meets the requirements described below, a series of
the Fund will modify the $1,000 initial investment requirement to such minimum
investment as may be determined by the Fund. The sales charge set forth under
"Purchase of Shares" for each purchase by a participant of a Group Program will
be based on (i) the combined current purchases of such group of shares together
with (ii) the combined net asset value of shares of such group at the time of
such investment. The dealer or agent, if any, through which the Group Program
was initiated will be entitled to a dealer concession or agency commission based
on the sales charges paid by participants of such Group Program.

     Criteria for the Group Program.  The cost savings criteria to the Fund that
must be met in order for a Group Program to qualify for the benefits set forth
above are:

            (a) The administrator of an investor's investment program must have
     entered into an agreement with the Distributor.

                                     -20-
<PAGE>
 
          (b) Such agreement must provide that the administrator must submit a
      single order and make payment with a single remittance for all investments
      during each investment period (e.g., each pay period or distribution
      period) by all investors who choose to invest through the Group Program.

          (c) Such agreement must provide that the administrator will provide
     the Transfer Agent with appropriate backup data for each participating
     investor in a computerized format compatible with the Transfer Agent's
     processing system.

     Additional Criteria for the Group Program. As further requirements for
obtaining these special benefits under the Group Program, the Fund requires that
investments be in the form of an Open Account (with no share certificates being
issued), that all dividends and other distributions be reinvested in additional
shares without any systematic withdrawal program described herein and that the
minimum new investment in shares of the Fund by each participant in an employee
investment program be at least $25 per month. The Fund reserves the right to
modify or terminate this program at any time without notice.

Systematic Withdrawal Program

     The owner of $10,000 or more of shares of the Fund (which may not be in
certificated form) may provide for the payment from his or her account of any
requested dollar amount to his or her designated payee monthly, quarterly or
annually. Sufficient shares will be redeemed from the investor's account for the
designated amount so that the payee will receive it approximately the first of
each month. Dividend distributions automatically will be reinvested under this
program. Depending upon the size of the payments requested, redemptions for the
purpose of making such payments may reduce or even exhaust the account. The
program may be terminated at any time by the investor. If an investor desires to
utilize this program, he or she may so indicate on the Account Application
included with this Prospectus.

     It ordinarily will be disadvantageous to an investor to purchase shares
(except through reinvestment of distributions) while participating in a
systematic withdrawal program because he or she will be paying a sales charge to
purchase shares at the same time that shares are being redeemed upon which such
investor may already have paid a sales charge. Therefore, the Fund will not
knowingly permit an investor to make additional investments of less than $10,000
if an investor is at the same time making systematic withdrawals at a rate
greater than the dividend distributions being paid on such investor's shares.
The Fund reserves the right to amend or terminate the systematic withdrawal
program on thirty days' notice, and investors may withdraw from the program at
any time. The Fund reserves the right to modify or terminate this program at any
time.

Preauthorized Investment Program

     An investor may establish an automatic investment program with his or her
Fund account. With the Preauthorized Investment Program, monthly investments
(minimum

                                     -21-
<PAGE>
 
$100) are made automatically from an investor's account at a bank, savings and
loan or credit union into such investor's Fund account. By enrolling in the
Preauthorized Investment Program, the investor authorizes the Fund and its
agents to take money out of his or her predesignated bank, savings and loan or
credit union account and invest that money in his or her Fund account. If an
investor also has expedited wire transfer redemption privileges with his or her
Fund account, such investor must designate the same bank, savings and loan or
credit union account for both the Preauthorized Investment Program and wire
redemption programs. Any account owner may terminate this privilege simply by
sending written notice to the Transfer Agent. Termination will become effective
as soon as the Transfer Agent has had a reasonable time to act upon the request.
The Preauthorized Investment Program may not be used with passbook savings
accounts. Fund shares purchased by the Preauthorized Investment Program must be
owned for 15 days before they may be redeemed. If an investor desires to utilize
this program, he or she may so indicate on the Account Application included with
this Prospectus. The Fund reserves the right to modify or terminate this program
at any time.

Rights of Accumulation

     A purchase of shares may qualify for a cumulative quantity discount. The
applicable sales charge will be based on the total of:

          (a) the investor's current purchase; and

          (b) the net asset value (at the close of business on the
     previous day) of the shares of the Fund held by an investor.

     For example, if an investor owned shares worth $40,000 at the current net
asset value and purchased an additional $10,000 of shares, the sales charge for
the $10,000 purchase would be at the rate applicable to a single $50,000
purchase.

     To qualify for the cumulative quantity discount on a purchase through a
broker-dealer, when each purchase is made, the investor or broker-dealer must
provide the Fund with sufficient information to verify that the purchase
qualifies for the discount.

Reinstatement Privilege

     An investor who has redeemed shares of the Fund may reinvest up to the full
amount of such redemption at net asset value at the time of reinvestment. An
investor using this privilege a year or more after such investor redeemed shares
of the Fund must file a new account application and provide proof that such
investor was a shareholder of the Fund. See "Dividends and Taxes" regarding the
potential tax implications of exercising this privilege. The Fund reserves the
right to modify or terminate this privilege at any time without notice.

                                     -22-
<PAGE>
 
                             REDEMPTION OF SHARES

     Upon receipt of a redemption request in proper form addressed to the
Transfer Agent, shares of the Fund will be redeemed by the Fund. It is a
broker's or dealer's responsibility to promptly forward the redemption requests
to the Transfer Agent for shares being redeemed in order for shareholders to
receive the next determined net asset value. The redemption price for shares of
the Fund is based on the net asset value per share next determined after receipt
of the redemption request. Redemption requests must be in writing, accompanied
by any issued certificates (for investor protection, certificates should be sent
by registered mail). Redemption requests and any certificates or stock power
must be endorsed by all registered owners with signatures guaranteed by a member
firm of a national securities exchange or by a commercial bank, savings and loan
association or trust company. Further documentation may be requested from
corporations, executors, administrators, trustees or guardians.

     Alternatively, an investor may place an order to sell shares (whether in
certificate or book entry form) through his or her dealer or agent which has a
sales agreement with the Distributor and from which this Prospectus was
received, which dealer or agent will telephone such request to the Distributor.
The investor will receive the net asset value next determined after the
Distributor receives such sell order from the dealer or agent. The Fund does not
charge for this transaction.

     Whether shares are redeemed by the Fund or sold through an investor's
dealer or agent, a check for the proceeds ordinarily will be mailed to an
investor or his or her dealer or agent within three business days after a
redemption request or repurchase order and Share certificates (if any) are
received in proper form as set forth above.

     If a request to redeem shares is received shortly after the purchase of
such shares, the Fund will not mail the proceeds until checks received for the
purchase of shares have cleared, which may take up to 15 days. The proceeds of a
redemption may be more or less than the cost of the shares.

     The right of redemption or resale of the Fund shares may be suspended or
the date of payment postponed during any period when the New York Stock Exchange
is closed.

                              DIVIDENDS AND TAXES

Dividends

     The Fund will declare distributions on a daily basis to shareholders of
record on the date of each declaration and will pay such distributions on a
monthly basis. The monthly distribution will be composed of the investment
income earned by the Fund less the expenses of the Fund plus all or a portion of
net short-term capital gains (such net short-term capital gains reduced by net
long-term capital losses, if any, and carryover capital losses from previous
years) realized by the Fund on transactions in securities. The Fund will also

                                     -23-
<PAGE>
 
declare and make distributions of net long-term capital gains, if any, at least
annually. Net long-term capital gain distributions consist of the realized long-
term capital gains on transactions in securities of the Fund, net of certain
realized capital losses and less certain carryover capital losses from previous
years.

     The Fund automatically will credit monthly distributions and any capital
gain distributions to an investor's account in additional shares of the Fund
valued at net asset value on the date such distributions are payable, without
sales charge, unless an investor elects to the Transfer Agent of the Fund to
have distributions received in cash. Distributions that are reinvested are
treated as cash distributions for income tax purposes. If an investor elects to
change the method of distribution, such change will be effective only with
regard to distributions for which the payment date is seven or more business
days after the Transfer Agent has received the written request.

     A check will be generated on the date on which distributions are payable
for dividends to be received in cash. An investor can expect to receive this
check within seven days. If the U. S. Postal Service cannot deliver the check,
or if the checks remain uncashed for six months, the checks will be reinvested
in the investor's account at the then-current net asset value and all future
dividends will be reinvested.

     Distribution checks may be sent to parties other than the investor.  The
Transfer Agent of the Fund can provide investors with a "Dividend Order" form
for such purposes.  After the Transfer Agent receives this completed form with a
signature guarantee, distribution checks will be sent to the bank or other
person designated as an investor.

Taxes

     The Fund intends to qualify each year as a regulated investment company
under Subchapter M of the Internal Revenue Code (the "Code") and, if so
qualified, will generally not be liable for federal income taxes to the extent
it timely distributes its earnings. If in any year the Fund should fail to
qualify under Subchapter M for tax treatment as a regulated investment company,
the Fund would incur a regular corporate federal income tax upon its taxable
income for that year, and distributions to shareholders of the Fund would be
taxable to such shareholders as ordinary income to the extent of the earnings
and profits of the Fund, including distributions that would otherwise qualify as
exempt-interest dividends. For shareholders of the Fund that are corporations,
such distributions would be eligible for the dividends-received deduction. In
addition, the Fund intends to invest in sufficient municipal securities so that
it will qualify to pay "exempt-interest dividends" (as defined in the Code) to
shareholders; the Fund's dividends payable from net tax-exempt interest earned
from municipal securities will qualify as exempt-interest dividends if, at the
close of each quarter of the taxable year of the Series, at least 50% of the
value of the Fund's total assets consists of tax-exempt municipal securities.

     Exempt-interest dividends distributed to shareholders generally are not
subject to federal income tax except to the extent such interest is subject to
the alternative minimum tax, as discussed hereinafter. The percentage of income
that is tax-exempt is applied 

                                     -24-
<PAGE>
 
uniformly to all distributions made during each calendar year and thus is an
annual average for the Fund rather than a day-by-day determination for each
shareholder whether received in shares or in cash. The percentage of all
distributions of earnings other than exempt-interest dividends paid by the Fund,
such as net investment income received from investments in debt securities other
than tax-exempt municipal securities, and any net realized short-term capital
gains (including certain amounts deemed distributed) will generally be taxable
to the shareholders as ordinary income. Any distribution of net related long-
term capital gains (including amounts deemed distributed) will generally be
subject to federal taxation as long-term capital gains ("long-term capital gain
distributions"), regardless of the length of time the investor has held such
shares.

     "The Revenue Reconciliation Act of 1993" (the "Tax Act") subjects tax-
exempt municipal securities to the market discount rules of the Code effective
for municipal securities purchased after April 30, 1993. In general, market
discount is the amount (if any) by which the stated redemption price at maturity
exceeds an investor's purchase price (except to the extent that such difference,
if any, is attributable to original issue discount not yet accrued), subject to
a statutory de minimis rule. Market discount can arise based on the price the
Fund pays for municipal securities. Under the Tax Act, accretion of market
discount is taxable as ordinary income; under prior law the accretion had been
treated as capital gain. Market discount that accretes while the Fund holds a
municipal security would be recognized as ordinary income by the Fund when
principal payments are received on the municipal security, or upon sale or at
redemption (including early redemption), unless the Fund elects to include
market discount in taxable income as it accrues. Distributions to shareholders
of the Fund, to the extent of any market discount that is included in the Fund's
taxable income, would be taxable to shareholders as ordinary income.

     For both individuals and corporations, interest paid on certain "private
activity bonds" issued on or after August 8, 1986 shall be treated as an item of
tax preference and may, therefore, be subject to the alternative minimum tax. To
the extent provided by regulations to be issued by the Secretary of the
Treasury, exempt-interest dividends paid by the Fund will be treated as interest
on private activity bonds to the extent of the proportionate amount of interest
on such private activity bonds received by the Fund. Such exempt-interest
dividends constitute a tax preference item subject to both the individual and
corporate alternative minimum tax. The Fund will annually supply shareholders
with a report indicating the percentage of Fund income attributable to bonds
subject to the alternative minimum tax.

     Exempt-interest dividends received by a shareholder which are not with
respect to certain "private activity bonds" are not treated as a tax preference
item. However, for certain corporate shareholders such dividends will be
included in the computation of an adjustment item used in determining such
corporation's alternative minimum tax and environmental tax (the "Superfund
Tax"). The adjustment item is 75% of the excess of such corporate shareholder's
"adjusted current earnings" over its other alternative minimum taxable income
with certain adjustments. Although exempt-interest dividends received by a
shareholder will not be included in the gross income of corporations for federal
income tax purposes, "adjusted current earnings" include all tax-exempt
interest, including exempt-

                                     -25-
<PAGE>
 
interest dividends received from the Fund. Corporate shareholders are advised to
consult their tax advisors with respect to the tax consequences of the
alternative minimum tax, the Superfund Tax and the branch profits tax under
Section 884 of the Code.

     For taxpayers other than corporations, net capital gains are presently
subject to a maximum stated marginal tax rate of 28%. All taxpayers are required
to disclose to the Internal Revenue Service on their tax returns the amount of
tax-exempt interest earned during the year including exempt-interest dividends
from the Fund.

     The hedging activities and transactions in options and futures contracts of
the Fund are subject to special tax provisions that may accelerate or defer
recognition of certain taxable gains or losses, or alter the holding periods of
certain of the Fund's securities, or convert capital gain into ordinary income
and convert short-term capital losses into long-term capital losses. These rules
could therefore affect the amount, timing and character of distributions to
shareholders. Recognition of unrealized taxable gains by the Fund under the
"mark to market" rules of the Code may increase the difficulty of compliance
with requirements which must be satisfied in order for the Fund to continue to
qualify as a regulated investment company, thus requiring the Fund to limit its
hedging activities. Such activities also may be limited by the requirement that
the Fund derive less than 30% of its annual gross income from the sale or other
disposition of securities held for less than three months in order to qualify as
a regulated investment company under the Code.

     Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in one of those months and paid during January of the
following year will be treated as having been distributed by the Fund (and
received by the shareholders) on December 31 of the year such dividends are
declared.

     Distributions from the Fund will not generally be eligible for the
dividends received deduction for corporations.

     The Fund is required by law to withhold a specified percentage of taxable
dividends and certain other payments, including redemption payments, paid to 
non-corporate investors who do not certify to the Fund their correct taxpayer
identification number (in the case of individuals, their social security number)
and in certain other circumstances as may be required by the Code.

     Under Section 86 of the Code, up to 50% of a social security recipient's
benefits may be included in taxable income for a benefit recipient if the sum of
his adjusted gross income, income from tax-exempt sources such as tax-exempt
bonds and distributions made by the Fund plus 50% of his social security
benefits exceeds certain base amounts. Income from the Fund is still tax-exempt
to the extent described above; it is only included in the calculation of whether
a recipient's income exceeds certain established amounts.

     Redemption of shares of the Fund will be a taxable transaction for federal
income tax purposes and such investors will generally recognize gain or loss in
an amount equal to the 

                                     -26-
<PAGE>
 
difference between the basis of the shares and the amount received. Assuming
that investors hold such shares as a capital asset, the gain or loss will be a
capital gain or loss and will generally be long-term if investors have held such
shares for a period of more than one year. In the case of shareholders holding
shares of the Fund for six months or less and subsequently selling those shares
at a loss after receiving an exempt-interest dividend, the loss will be
disallowed to the extent of the exempt-interest dividends received. If such loss
is not entirely disallowed, it will be treated as a long-term capital loss to
the extent any long-term capital gain distribution is made with respect to such
shares during the six-month period or less that the investor owns the shares. If
a loss is realized on the redemption of Fund shares, the reinvestment in
additional Fund shares or the acquisition of a contract or option to acquire
securities that are substantially identical to Fund shares within 30 days before
or after the redemption may be subject to the "wash sale" rules of the Code,
resulting in a postponement of the recognition of such loss for federal income
tax purposes. In addition, an investor cannot take into account any sales or
similar charge incurred in acquiring shares of the Fund (a "load charge," such
charge does not include amounts paid with respect to the reinvestment of mutual
fund share dividends) in computing gain or loss on the sale of shares of the
Fund if the investor sells such shares within 90 days of the date the shares are
acquired and the investor obtains and subsequently exercises the right to
reinvest in shares of any mutual fund without the payment of a load charge or
with the payment of a reduced charge (however, such charges shall be treated as
incurred in connection with the reinvestment in shares).

     The Tax Act raised tax rates on ordinary income while capital gains remain
subject to a 28 percent maximum stated rate. Because some or all capital gains
are taxed at a comparatively lower rate under the Tax Act, the Tax Act includes
a provision that recharacterizes capital gains as ordinary income in the case of
certain financial transactions that are "conversion transactions" effective for
transactions entered into after April 30, 1993. It is possible that this
provision could result in the recharacterization of amounts or distributions
otherwise characterized as capital gains by the Fund or a shareholder as
ordinary income. Shareholders of the Fund should consult with their tax advisors
regarding the potential effect of this provision on their investment in shares
of the Fund.

     Interest on indebtedness which is incurred to purchase or carry shares of a
mutual fund which distributes exempt-interest dividends during the year is not
deductible for federal income tax purposes. Further, the Fund may not be an
appropriate investment for persons who are "substantial users" of facilities
financed by industrial development bonds held by the Fund or are "related
persons" to such users; such persons should consult their tax advisors before
investing in the Fund.

     State and Local Tax Aspects.  To the extent that exempt-interest dividends
are derived from interest on Oklahoma Municipal Securities that is exempt from
the Oklahoma income tax, such dividends will also qualify as exempt from the
Oklahoma income tax. However, to the extent that exempt-interest dividends are
derived from interest on Oklahoma Municipal Securities that is not exempt from
Oklahoma income tax, such dividends will be taxable for Oklahoma income tax
purposes to the shareholders of the Fund. As discussed earlier, the Fund may
invest up to 30% of its total assets in Oklahoma Municipal Securities which are

                                     -27-
<PAGE>
 
subject to Oklahoma state income taxes. Any nonqualifying exempt-interest
dividends and dividends taxable for federal income tax purposes as ordinary
income will be taxable for Oklahoma income tax purposes to the shareholders of
the Fund. Distributions treated as long-term capital gains for federal income
tax purposes will generally receive the same characterization under Oklahoma
law.

     Except as described above with respect to Oklahoma income taxation, the
exemption from federal income tax for exempt-interest dividends does not
necessarily result in exemption for such dividends under the income or other tax
laws of any state or local taxing authority. Taxpayers should consult their own
advisors regarding the consequences under such taxes with respect to the
purchase, ownership, and disposition of shares of the Fund.

     The tax discussion set forth above is for general information only.
Annually, shareholders of the Fund receive information as to the tax status of
distributions made by the Fund in each calendar year. The foregoing relates to
federal income taxation and to Oklahoma income taxation as in effect as of the
date of this Prospectus. Investors should consult their own tax advisors
regarding the federal, state, local, foreign and other tax consequences of an
investment in the Fund, including the effects of any change, including any
proposed change, in the tax laws.

                       DESCRIPTION OF SHARES AND RIGHTS

     The Fund's Agreement and Declaration of Trust ("Trust Agreement") permits
its Trustees to issue an unlimited number of shares, without par value, from
each Series that is designated by the Board of Trustees. Each share of a Series
represents an equal proportionate interest in the assets and liabilities
belonging to the Series with each other share of such Series and is entitled to
such dividends and distributions out of the income belonging to the Series as
are declared by the Trustees. The shares do not have cumulative voting rights
nor any preemptive rights. In case of a liquidation, subject to the rights of
creditors, the holders of the shares of the Series being liquidated will be
entitled to receive a distribution out of the net assets belonging to the Series
being liquidated. Should additional Series be designated by the Board of
Trustees, the net asset value of the shares of each of such Series will be
computed based only upon the net assets of each such Series.

     Under Massachusetts law, if certain conditions prevail, shareholders of a
Massachusetts business trust could be deemed to have the same type of personal
liability for the obligations of the Fund as does a partner of a partnership.
The Trust Agreement contains an express disclaimer of liability on the part of
Fund shareholders and provides that the Fund shall assume the defense on behalf
of its shareholders. Thus, the risk of Fund shareholder liability is slight and
limited to a circumstance where a Series itself is unable to meet its
obligations.

     As a Massachusetts business trust, the Fund is not required to and does not
intend to hold annual shareholders' meetings. However, the Trust Agreement
provides for Fund shareholder voting with respect to certain matters, including:
(a) the election or removal of Trustees if a meeting is called for that purpose;
(b) any contract as to which shareholder

                                     -28-
<PAGE>
 
approval is required by the Investment Company Act of 1940, as amended (the
"1940 Act"); (c) any termination or reorganization of the Fund or any Series of
the Fund to the extent provided in the Trust Agreement; and (d) any amendment of
the Trust Agreement (other than amendments designating new Series, changing the
name of the Fund or any Series of the Fund, supplying any omission, curing any
ambiguity, or curing, correcting or supplementing any provisions inconsistent
with the 1940 Act or the Code). Meetings of shareholders may be called upon
written application specifying the purpose of the meeting by shareholders
holding at least 25% (or 10% if the purpose of the meeting is to determine if a
Trustee is to be removed from office) of the shares then outstanding. In
connection with the shareholders' right to remove a Trustee, shareholders will
be assisted with their communications in such matter.

                                FUND MANAGEMENT

     The business and affairs of the Fund will be managed under the direction of
the Board of Trustees.  The Trustees are subject to the fiduciary
responsibilities imposed by the laws of the Commonwealth of Massachusetts.
Subject to the Trustees' authority, Ranson Capital Corporation, a Kansas
corporation, 1 North Main, Minot, North Dakota 58703, the Manager, will
supervise and implement the Fund's investment activities and will be responsible
for overall management of the Fund's business affairs.  Ranson Capital
Corporation is also the investment adviser of the Fund and will perform certain
evaluations of the securities held by the Fund.  The Fund will pay the Manager a
monthly management and investment advisory fee equivalent on an annual basis to
 .50 of 1% of its average daily net assets.

     Overall portfolio management strategy for the Fund is determined by the
Manager under the general supervision and direction of Robert E. Walstad, the
President of the Fund and the Manager.  Mr. Walstad is also the President of
five other open-end funds and of ND Money Management, Inc., their investment
adviser, and has supervised and directed the management of their portfolios
since they commenced operations.  The day-to-day management of the Fund,
including credit analysis and the execution of portfolio transactions, is the
responsibility of _______________________.  All portfolio management decisions
are subject to weekly review by Mr. Walstad and to quarterly review by the
Fund's Board of Trustees.

     The Manager is a broker-dealer registered with the Securities and Exchange
Commission and a wholly-owned subsidiary of The Ransom Company, Inc., a Kansas
corporation.  All of the outstanding shares of stock of The Ranson Company,
Inc., are owned by ND Holdings, Inc., a North Dakota corporation.  The Manager
was formed in 1990 and is also the investment adviser for The Kansas Municipal
Fund, The Kansas Insured Intermediate Fund and The Nebraska Municipal Fund,
which have current net asset values of $________, $__________ and $___________,
respectively.  The Manager has not retained the right to withdraw from the Fund
the use of the name "Ranson," but the Manager may grant the use of the name
"Ranson" to another investment company.

                                     -29-
<PAGE>
 
     Under the terms of the Management and Investment Advisory Agreement, the
Manager has agreed to pay all expenses of the Fund, including the Fund's
management and investment advisory fee and the Fund's administrative and
accounting services fees (but excluding taxes and brokerage fees and
commissions, if any) that exceed 1.25% of the Fund's average daily net assets on
an annual basis up to the amount of the investment advisory and management fee
payable by the Fund to the Manager. Reimbursements by the Manager for such Fund
expenses will be paid monthly based on annualized year to date expenses. All
other expenses shall be paid by the Fund. From time to time and subject to
discontinuance at any time, the Manager may voluntarily assume certain expenses
of the Fund. This will have the effect of lowering the overall expense ratio of
the Fund and of increasing yield to investors. The Fund's expenses include,
among others, taxes, brokerage fees and commissions, if any, fees of
Disinterested Trustees, expenses of Trustees' and shareholders' meetings,
insurance premiums, expenses of redemption of shares, expenses of issue and sale
of shares (to the extent not borne by the Distributor), expenses of printing and
mailing certificates, association membership dues, charges of the Fund's
custodian, and bookkeeping, auditing and legal expenses, and the fees and
expenses of registering the Fund and its shares with the Securities and Exchange
Commission, registering or qualifying its shares under state securities laws and
the expenses of preparing and mailing prospectuses and reports to shareholders.

     ND Resources, Inc. ("Resources"), a wholly-owned subsidiary of ND Holdings,
Inc., a North Dakota corporation, acts as the Fund's administrative and
accounting services agent. For these services, Resources receives an
administrative and accounting services fee payable monthly from the Fund equal
to the sum of (i) $2,000 per month and (ii) 0.05% of the Fund's average daily
net assets on an annual basis for the Fund's first $50 million of average daily
net assets, 0.04% of the Fund's average daily net assets on an annual basis for
the Fund's next $50 million of average daily net assets, 0.03% of the Fund's
average daily net assets on an annual basis for the Fund's next $100 million of
average daily net assets, 0.02% of the Fund's average daily net assets on an
annual basis for the Fund's next $300 million of average daily net assets, and
0.01% of the Fund's average daily net assets on an annual basis for the Fund's
average daily net assets in excess of $500 million, together with reimbursement
of Resources' out-of-pocket expenses. This fee and reimbursement are in addition
to the investment advisory and management fee received by the Manager, which is
also indirectly owned by ND Holdings, Inc., from the Fund.

     The Board of Trustees has the authority, without shareholder approval, to
determine who will perform the following services for the Fund: securities
evaluator; custodian of the Fund's securities and cash; and, dividend
disbursing, administrative and accounting services agent.

     In effecting purchases and sales of the Fund's portfolio securities, the
Manager and the Fund may place orders with and pay brokerage commissions to
brokers which are affiliated with the Fund, the Manager, the Distributor or
selected dealers participating in the offering of the Fund's shares. In
addition, in selecting among firms to handle a particular transaction, the
Manager and the Fund may take into account whether the firm has sold or is
selling shares of the Fund. Subject to rules adopted by the Securities and
Exchange

                                     -30-
<PAGE>
 
Commission, the Fund may also purchase municipal securities from other
members of underwriting syndicates of which the Distributor or other affiliates
of the Fund are members.

                                THE DISTRIBUTOR

     Shares of the Fund are offered on a continuous basis through Ranson Capital
Corporation, a Kansas Corporation, 1 North Main, Minot, North Dakota 58703.
Pursuant to a Distribution and Services Agreement, the Distributor will purchase
shares of the Fund for resale to the public, either directly or through
securities dealers or agents, and is obligated to purchase only those shares for
which it has received purchase orders. In addition to agreements with securities
dealers, the Distributor may enter into agreements with banks or bank affiliates
with respect to the sale of shares of the Fund. Under the Glass-Steagall Act,
banks and bank affiliates are prohibited from underwriting Fund shares; however,
the Glass-Steagall Act does permit certain agency transactions and the banking
regulators have not indicated that these particular agency transactions are not
permitted under such Act. In the event the Glass-Steagall Act should prevent
banks or bank affiliates from acting in any capacity or providing investor
administrative and shareholder services, the Fund's Trustees will consider what
action, if any, is appropriate in order to provide efficient services to the
Fund. It is anticipated that a termination of a relationship with a bank or bank
affiliate would not result in a loss to investors or a change in net asset
value.

     Under the Distribution and Services Agreement between the Fund and the
Distributor, the Distributor pays the expenses of distribution of the Fund's
shares, including preparation and distribution of literature relating to the
Fund and its investment performance and advertising and public relations
material. The Fund bears the expenses of registration of its shares with the
Securities and Exchange Commission and of sending prospectuses to existing
shareholders. The Distributor will permit their officers and employees to serve
without compensation as Trustees and officers of the Fund if duly elected to
such positions. The Fund will pay the cost of qualifying and maintaining
qualification of the shares for sale under the securities laws of the various
states if necessary. In addition, under the plan adopted pursuant to Rule 12b-1
under the Investment Company Act of 1940 and under which the Fund will pay some
costs of the distribution of its shares, the Fund will pay the Distributor .25%
of the average daily net assets of the Fund and the Distributor may in turn pay
firms that sell the Fund's shares an annual service fee of up to .25% of average
daily net assets of customer accounts in existence for more than one year for
administrative and shareholder services or use some or all of such payment to
pay other distribution expenses which otherwise would be payable by the
Distributor.

     The Distribution and Services Agreement continues in effect from year to
year if specifically approved at least annually by the shareholders or Board of
Trustees of the Fund and by the Fund's disinterested Trustees in compliance with
the Investment Company Act of 1940. The agreement may be terminated without
penalty upon sixty days' written notice by the Fund or ninety days' written
notice by the Distributor and will automatically terminate if it is assigned.

                       SHAREHOLDER SERVICES AND REPORTS

     First Western Bank & Trust serves as Custodian of the Fund and will have
custody of all securities and cash of the Fund and will attend to the collection
of principal and income and payment for and collection of proceeds of securities
bought and sold by the Fund.

     ND Resources, Inc. is the Transfer Agent for the Fund and will perform
bookkeeping, data processing and administrative services related to the
maintenance of shareholder accounts.  When an investor makes an initial
investment in the Fund, an account will be opened on the Fund's books and the
investor will receive a confirmation of the opening of the account.  An investor
will receive monthly statements giving details of all activity in his or her
account and will receive a statement whenever investments in or withdrawals from
such account are made.  The statement with tax information for the year will be
mailed to investors by January 31 and will also be filed with the Internal
Revenue Service.

     As a rule, the Fund will not issue share certificates.  However, upon
written request to the Transfer Agent, a share certificate will be issued for
any or all of the full shares credited to an investor's account.  Share
certificates which have been issued may be returned at any time.

     Investors will receive annual financial statements, together with a report
of independent auditors, and semiannual unaudited financial statements.
Investors will also receive notices of shareholders' meetings.  Shareholder
inquiries regarding their account should be directed to the Transfer Agent.

                     CALCULATION OF FUND PERFORMANCE DATA

     From time to time, the Fund may advertise several types of performance
information.  These are "current yield," "tax equivalent yield," "average annual
total return" and "total return." Each of these figures is based upon historical
results and is not necessarily representative of the future performance of the
Fund.

     Current yield is determined by annualizing net investment income earned per
share for a stated period (normally one month or thirty days) and dividing the
result by the maximum public offering price at the end of the evaluation period.

     Tax equivalent yield is determined by dividing that portion of current
yield which is tax-exempt by one minus a stated combined state and federal
income tax rate and adding that portion of the current yield, if any, that is
not tax-exempt.

     The Fund's distribution return is computed by dividing that portion of
current yield which is tax-exempt by one minus a stated combined state and
federal income tax rate and adding that portion of the current yield, if any,
that is not tax-exempt.

     Average annual total return and total return figures measure both the net
investment income generated by the Fund and the effect of any realized or
unrealized appreciation or 

                                     -32-
<PAGE>
 
depreciation of the underlying investments in the portfolio of the Fund for the
period in question, assuming the reinvestment of all dividends and capital gains
distributions. Thus, these figures reflect the change in the value of an
investment in the Fund during a specified period. Average annual total return
will be quoted for at least the one, five and ten year periods ending on a
recent calendar quarter (or if such periods have not yet elapsed, at the end of
a shorter period corresponding to the life of the Fund). Average annual total
return figures are annualized and, therefore, represent the average annual
percentage change over the period in question. Total return figures are not
annualized and represent the aggregate percentage or dollar value change over
the period in question.

     From time to time, the Fund's performance may be compared to that of the
Consumer Price Index or various unmanaged bond indexes and may also be compared
to the performance of other fixed income or government bond mutual funds or
mutual fund indexes as reported by entities such as Lipper Analytical Services,
Inc. ("Lipper").  Lipper is a widely recognized independent mutual fund
reporting service.  Lipper performance calculations are based upon changes in
net asset value with all dividends reinvested and do not include the effect of
any sales charges.

     The Fund's shares are sold at net asset value plus a maximum sales charge
of 4.25% of the offering price.  While the maximum sales charge is normally
reflected in the Fund's performance figures, certain total return calculations
may not include such charge and those results would be reduced if it were
included.  The Fund's returns and net asset value will fluctuate.  Shares of the
Fund are redeemable by an investor at the then current net asset value, which
may be more or less than original cost.

                             SUMMARY OF PROCEDURES

     The following summary is intended as a reference guide for investors.  It
is not intended to be comprehensive.  Investors should read the main body of the
Prospectus and consult with their dealer, agent or the Fund's customer service
representatives as necessary.

PURCHASES

REDEMPTIONS

     REDEMPTION REQUESTS must be signed by all registered owners, accompanied by
signature guarantee(s).  Fund shares held in certificate form must be submitted
in proper form to effect redemption.  The Transfer Agent may request such other
documentation from corporations, executors, administrators, trustees or
guardians as is deemed necessary to determine the authority of the individual
making the request.

     REDEMPTION REQUESTS AND OTHER TRANSFER AGENT INQUIRIES should be sent to
the Fund, c/o the Transfer Agent.

OTHER

     ADDRESS CHANGES:  A new address should be indicated on the remittance

                            THE FUND AND ITS SHARES

     The Oklahoma Municipal Fund is a newly-organized series of Ranson Managed
Portfolios, an open-end non-diversified management investment company organized
as an unincorporated business trust under the laws of Massachusetts on August
10, 1990.

     Prior to the sale of shares of the Fund to the public, all shares of the
fund were owned by Ranson Capital Corporation. Since the Fund is newly formed,
as of the date of this Statement of Additional Information, Ranson Capital
Corporation controls 100% of the shares of the Fund.

                INVESTMENT OBJECTIVE, POLICIES AND RESTRICTIONS

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "Investment Objective and
Policies."

     The investment objective of the Fund is to provide its shareholders with as
high a level of current income that is exempt from both federal income tax and
Oklahoma income tax, to the extent indicated, as is consistent with preservation
of capital. Under normal market conditions, the Fund's assets will be invested
in a portfolio of Oklahoma Municipal Securities which, in the opinion of Ranson
Capital Corporation, will produce a higher level of current income than would be
produced by a portfolio of Oklahoma Municipal Securities rated in only the
highest rating category, but contains Oklahoma Municipal Securities which do not
present a significant risk of loss of principal due to credit characteristics.
Up to 30% of the Fund's total assets may be invested in Oklahoma Municipal
Securities which are subject to Oklahoma state income taxes.

     The investment policy of the Fund is to invest at least 70% of its assets
in a portfolio of Oklahoma Municipal Securities which generate interest income
that is exempt from both federal income tax and Oklahoma income tax. Oklahoma
Municipal Securities generally include debt obligations of the State of
Oklahoma, its political subdivisions, municipalities, agencies and authorities,
and certain industrial development and other revenue bonds, short-term municipal
notes, municipal leases and commercial paper issued by such entities and
obligations of the Commonwealth of Puerto Rico, the Virgin Islands and Guam.

     Futures Contracts, Options on Futures and Municipal Bond Index Futures. The
Fund may purchase or sell financial futures contracts ("futures contracts") and
related options thereon. These futures contracts and related options thereon
will be used only as a hedge against anticipated interest rate changes. In
general a futures contract sale creates an obligation by the Fund, as seller, to
deliver the specific type of instrument called for in the contract at a
specified future time for a specified price. A futures contract purchase would
generally create an obligation by the Fund, as purchaser, to take delivery of
the specific type of financial instrument at a specified future time at a
specified price. The specific securities delivered or taken, respectively, at
settlement date would not be determined until on or near that date. The
determination would be in accordance with the rules of the exchange on which the
futures contract sale or purchase was effected.

                                      -2-
<PAGE>
 
     Although the terms of futures contracts specify actual delivery or receipt
of securities, in most instances the contracts are closed out before the
settlement date without the making or taking of delivery of the securities.
Closing out a futures contract is usually effected by entering into an
offsetting transaction. An offsetting transaction for a futures contract sale is
effected by the Fund entering into a futures contract purchase for the same
aggregate amount of the specific type of financial instrument at the same
delivery date. If the price in the sale exceeds the price in the offsetting
purchase, the Fund immediately is paid the difference and thus realizes a gain.
If the offsetting purchase price exceeds the sale price, the Fund pays the
difference and realizes a loss. Similarly, the closing out of a futures contract
purchase is effected by the Fund entering into a futures contract sale. If the
offsetting sale price exceeds the purchase price, the Fund realizes a gain, and
if the offsetting sale price is less than the purchase price, the Fund realizes
a loss.

     Unlike a futures contract, which requires the parties to buy and sell an
instrument on a set date, an option on a futures contract entitles its holder to
decide on or before a future date whether to enter into such a contract (a long
position in the case of a call option and a short position in the case of a put
option). If the holder decides not to enter into the contract, the premium paid
for the contract is lost. Since the cost of the option is fixed, there are no
daily payments of cash by the purchaser to reflect the change in the value of
the underlying contract as discussed below for futures contracts. The seller of
the option, however, may be required to make daily maintenance margin payments
to reflect the change in the value of the underlying contract. The value of the
option is reflected in the net asset value of the Fund.

     The Fund is required to maintain margin deposits with brokerage firms
through which it effects futures contracts and options thereon. The initial
margin requirements vary according to the type of the underlying instrument. In
addition, due to current industry practice, daily variations in gains and losses
on open contracts are required to be reflected in cash in the form of variation
margin payments. The Fund may be required to make additional margin payments
during the term of the contract.

     Currently, futures contracts can be purchased on debt securities such as
U.S. Treasury Bills and Bonds, U.S. Treasury Notes with maturities between 6-1/2
and 10 years, Certificates of the Government National Mortgage Association, Bank
Certificates of Deposit and on a municipal bond index (see below). The Fund may
purchase or sell interest rate futures contracts covering these types of
financial instruments as well as new types of contracts that become available in
the future.

     Financial futures contracts and related options contracts are traded in an
auction environment on the floors of several futures Exchanges--principally, the
Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures
Exchange.

     A risk in employing futures contracts to protect against the price
volatility of portfolio securities is that the prices of securities subject to
futures contracts may not correlate perfectly with the behavior of the cash
prices of the Fund's portfolio securities. The correlation may be distorted in
part by the fact that the futures market is influenced by

                                      -3-
<PAGE>
 
short-term traders seeking to profit from the difference between a contract or
security price objective and their cost of borrowed funds. This would reduce the
value of futures contracts for hedging purposes over a short time period. The
correlation may be further distorted since the futures contracts that are being
used to hedge are not based on municipal obligations.

     Another risk is that the Manager could be incorrect in its expectations as
to the direction or extent of various interest rate movements or the time span
within which the movements take place. For example, if the Fund sold futures
contracts in anticipation of an increase in interest rates, and then interest
rates went down, causing bond prices to rise, the Fund would lose money,
including transaction costs, on the sale.

     In addition to the risks associated with investing in options on
securities, there are particular risks associated with trading in options on
futures. In particular, the ability to establish and close out positions on such
options will be subject to the development and maintenance of a liquid market in
such options. It is not certain that this market will develop.

     A substantial majority (i.e., approximately 75%) of all anticipatory hedge
transactions (transactions in which the Fund does not own, at the time of the
transaction, but expects to acquire the securities corresponding to the relevant
futures contract) involving the purchase of futures contracts, call options or
written put options thereon will be completed by the purchase of securities
which are the subject of the hedge.

     The Fund may not enter into futures contracts or related options thereon
if, immediately thereafter, the amount committed to initial margin plus the
amount paid for option premiums on open contracts exceeds 5% of the value of the
Fund's total assets. In instances involving the purchase of futures contracts by
the Fund, an amount equal to the gross market value of the futures contract will
be deposited in a segregated account of cash and cash equivalents and thereby
ensure that the use of such futures is unleveraged. The Fund may not purchase or
sell futures contracts or related positions if, immediately thereafter, more
than one-third of its net assets would be hedged.

     The Fund may utilize trading in municipal bond index futures contracts for
hedging purposes. The strategy in employing such contracts will be similar to
that discussed above with respect to financial futures and options thereon. A
municipal bond index is a method of reflecting in a single number the market
value (based on an average of quotations from certain dealers) of many different
municipal bonds. The index fluctuates in response to changes in the market
values of the bonds included within the index. Unlike futures contracts on
particular financial instruments, futures on a municipal bond index will be
settled in cash if held until the close of trading in the contract. However, as
in any other futures contract, a position in the contract may be closed out by
purchase or sale of an offsetting contract for the same delivery month prior to
expiration of the contract. Because trading in municipal bond index futures
contracts has been taking place only for a short time, the Fund's ability to
utilize such contracts will be dependent upon the development and maintenance of
a market in such contract.

                                      -4-

     The Securities and Exchange Commission generally requires that when
investment companies, such as the Fund, effect transactions of the foregoing
nature, such funds must either segregate cash or high quality, readily
marketable portfolio securities with its custodian in the amount of its
obligation under such transactions, or cover such obligations by maintaining
positions in portfolio securities, futures contracts or options that would serve
to satisfy or offset the risk of such obligations. When effecting transactions
of the foregoing nature, the Fund will comply with such segregation or cover
requirements.

     Investment Restrictions.  Fundamental investment restrictions limiting the
investments of the Fund provide that the Fund may not:

               1.  Borrow money, except from banks for temporary or emergency
     (not leveraging) purposes and then in an amount not exceeding 10% of
     the value of the Fund's total assets (including the amount borrowed).
     The Fund will not borrow for leveraging purposes, and securities will
     not be purchased while borrowings are outstanding. Interest paid on
     any money borrowed will reduce the Fund's net income.

               2.  Pledge, hypothecate, mortgage or otherwise encumber its
     assets, in excess of 10% of the value of its total assets (taken at the
     lower of cost or current value) and then only to secure borrowings for
     temporary or emergency purposes.

               3.  Purchase securities on margin, except such short-term credits
     as may be necessary for the clearance of purchases and sales of securities.
     The deposit of initial or maintenance margin by the Fund in connection with
     financial futures contracts and related options transactions, including
     municipal bond index futures contracts or related options transactions, is
     not considered the purchase of a security on margin.

               4.  Make short sales of securities or maintain a short position
     for the account of the Fund including any short sales "against the box."

               5.  Underwrite the securities of other issuers, except to the
     extent that, in connection with the disposition of its portfolio
     investments it may be deemed to be an underwriter under federal securities
     laws.

               6.  Purchase or sell real estate, but this shall not prevent the
     Fund from investing in securities which are secured by real estate or
     interests therein.

               7.  Purchase or sell commodities or commodity contracts except to
     the extent the options and futures contracts the Fund may trade in are
     considered to be commodities or commodities contracts.

               8.  Make loans to others except through the purchase of qualified
     debt obligations and the entry into repurchase agreements.

               9.  Invest more than 25% of its total assets in the securities of
     issuers in any single industry; provided that there shall be no such
     limitation on the purchase of

                                      -5-
<PAGE>
 
     securities issued or guaranteed by the U.S. Government, its agencies or
     instrumentalities or by Oklahoma, its political subdivisions,
     municipalities, agencies and authorities. (The Fund may, from time to time,
     invest more than 25% of its assets in a particular segment of the municipal
     bond market; however, the Fund will not invest more than 25% of its assets
     in industrial development bonds in a single industry.)

               10.  Invest in securities of any issuer if, to the knowledge of
     the Fund, officers and Trustees of the Fund or officers and directors of
     the Manager who beneficially own more than 1/2 of 1% of the securities of
     that issuer together own more than 5%.

               11.  Purchase securities restricted as to resale, if, as a result
     such investment would exceed 5% of the value of the Fund's net assets.

               12.  Invest in (a) securities which at the time of such
     investment are not readily marketable, including participation interests in
     municipal leases, (b) securities the disposition of which is restricted
     under federal securities laws (as described in fundamental restriction (11)
     above) and (c) repurchase agreements maturing in more than seven days, if,
     as a result, more than 10% of such Fund's net assets (taken at current
     value) would be invested in securities described in (a), (b) and (c) above.

               13.  Invest more than 5% of its total assets in securities of any
     one issuer, except that this limitation shall not apply to securities of
     the U.S. Government, its agencies and instrumentalities and except that
     with respect to 50% of the Fund's total assets the Fund may invest up to
     25% of its total assets in securities of any one issuer.

     The Fund may not change any of these investment restrictions without the
approval of the lesser of (i) more than 50% of the Fund's outstanding shares or
(ii) 67% of the Fund's shares present or represented by proxy at a meeting at
which the holders of more than 50% of the outstanding shares are present or
represented by proxy. As long as the percentage restrictions described above are
satisfied at the time of the investment or borrowing, the Fund will be
considered to have abided by those restrictions even if, at a later time, a
change in values or net assets causes an increase or decrease in percentage
beyond that allowed.

     The following investment restrictions of the Fund may be changed by the
Board of Trustees of the Fund.

     The Fund will not:

           1.  Invest more than 5% of its total assets in the securities of any
     other single investment company, nor more than 10% of its total assets in
     the securities of two or more other investment companies, except as part of
     a merger, consolidation or acquisition of assets.

           2.  Buy or sell oil, gas or other mineral leases, rights or royalty
     contracts.

                                      -6-
<PAGE>
 
     An advisory fee will be charged for assets invested in securities of other
investment companies. However, the Fund will not invest more than 10% of its
total assets in such securities.

*    "Interested persons" as defined in the Investment Company Act of 1940.

(1)  Each of the named persons acted in the capacity of a Trustee. A new Board
     of Trustees (the first four persons in the list) was elected at a joint
     special meeting of the shareholders of the Fund comprising Ranson Managed
     Portfolios held on December 11, 1995, but did not assume office until the
     closing of the Stock Purchase Agreement between the shareholders of The
     Ranson Company, Inc., and ND Holdings, Inc., on January 5, 1996. The names
     of the Trustees who had served at any time during the fiscal year (8-1-94
     through 7-31-95) are enclosed in parentheses.

(2)  The compensation of any Trustee who is not an "interested person" as that
     term is defined in the Investment Company Act of 1940 is paid by the
     Manager. Until the closing of the Stock Purchase Agreement (see note (1)
     above), Trustees who were not interested persons of the Manager or the
     Distributor (the "Disinterested Trustees") were paid $500 plus expenses per
     meeting of the Board of Trustees and committees thereof attended by such
     Trustee. None of the Trustees who are interested persons received
     compensation for services as Trustees. Each of the Disinterested Trustees
     will be paid
                                      -8-

     a fee of $10,000 for the calendar year ending December 31, 1996, plus any
     expenses incurred in attending meetings. The $10,000 fee is apportioned
     among the eight funds comprised in the Integrity Mutual Funds group on the
     basis of gross assets.

     As of _____________________, 1996, the officers and Trustees of the Fund
     owned, as a group, less than 1% of the shares of the Fund.

                                   CUSTODIAN

     First Western Bank & Trust, 900 South Broadway, Minot, North Dakota 58701,
is the Custodian of the Fund and has custody of all securities and cash of the
Fund. The Custodian, among other things, attends to the collection of principal
and income, and payment for and collection of proceeds of securities bought and
sold by the Fund.

                             INDEPENDENT AUDITORS

     Shareholders will receive annual financial statements, together with a
report of independent auditors, and semi-annual unaudited financial statements
of the Fund. The independent auditors for the Fund are Brady, Martz &
Associates, P.C., 24 West Central Avenue, Minot, North Dakota 58701. The
independent auditors will report on the Fund's annual financial statements,
review certain regulatory reports and the Fund's income tax returns, and perform
other professional accounting, auditing, tax and advisory services when engaged
to do so by the Fund.

                 MANAGEMENT AND INVESTMENT ADVISORY AGREEMENT

     The Management and Investment Advisory Agreement (the "Agreement") between
the Manager and the Fund provides that the Manager will supply investment
research and portfolio management, including the selection of securities for the
Fund to purchase, hold or sell, and the selection of brokers through whom the
Fund's portfolio transactions are executed. The Manager also administers the
business affairs of the Fund, furnished offices, necessary facilities and
equipment, provides administrative services, and permits its officers and
employees to serve without compensation as directors and officers of the Fund if
duly elected to such positions. Fees and expense limitations under the Agreement
are described in the Prospectus.

     The Agreement will continue in effect from year to year if specifically
approved by the Fund's Trustees or the Fund's shareholders and by the Fund's
Disinterested Trustees in compliance with the requirements of the Investment
Company Act of 1940 (the "1940 Act"). The Agreement may be terminated without
penalty upon 60 days' written notice by either party and will automatically
terminate in the event of assignment.

     Ranson Capital Corporation serves as the Manager and is a wholly-owned
subsidiary of The Ranson Company, Inc., a Kansas corporation. ND Holdings, Inc.,
a North Dakota corporation owns all of the outstanding shares of common stock of
The Ranson Company, Inc.

                                      -9-
<PAGE>
 
                            PORTFOLIO TRANSACTIONS

     The Manager will place orders for portfolio transactions for the Fund with
broker-dealer firms giving consideration to the quality, quantity and nature of
each firm's professional services. These services include execution, clearance
procedures, wire service quotations and statistical and other research
information provided to the Fund and the Manager including quotations necessary
to determine the value of the Fund's net assets. Any research benefits derived
are available for all clients of the Manager. Since statistical and other
research information is only supplementary to the research efforts of the
Manager and still must be analyzed and reviewed by one of its staff, the receipt
of research information is not expected to materially reduce the Manager's
expenses. In selecting among the firms believed to meet the criteria for
handling a particular transaction, the Manager may take into consideration that
certain firms have sold or are selling shares of the Fund and that certain firms
provide market, statistical or other research information to the Fund and the
Manager, and may select firms that are affiliated with the Fund or the Manager.

     If it is believed to be in the best interests of the Fund, the Manager may
place portfolio transactions with brokers who provide the types of service
described above, even if it means the Fund will have to pay a higher commission
(or, if the broker's profit is part of the cost of the security, will have to
pay a higher price for the security) than would be the case if no weight were
given to the broker's furnishing of these services. This will be done, however,
only if, in the opinion of the Manager, the amount of additional commission or
increased cost is reasonable in relation to the value of the services.

     If purchases or sales of securities of the Fund and of one or more other
portfolios of the Fund, investment companies or clients supervised by the
Manager are considered at or about the same time, transactions in such
securities will be allocated among the several portfolios of the Fund,
investment companies and clients in a manner deemed equitable to all by the
Manager, taking into account the respective sizes of the funds and the amount of
securities to be purchased or sold. Although it is possible that in some cases
this procedure could have a detrimental effect on the price or volume of the
security as far as the Fund is concerned, it is also possible that the ability
to participate in volume transactions and to negotiate lower brokerage
commissions will be beneficial to the Fund. The Fund expects that its portfolio
transactions in Oklahoma Municipal Securities will generally be effected on a
principal (as opposed to agency) basis and, accordingly, does not expect to
incur significant brokerage commissions.

     While the Manager will be primarily responsible for the placement of the
Fund's business, the policies and practices in this regard must be consistent
with the foregoing and will at all times be subject to review by the Trustees of
the Fund.

     The Board of Trustees has adopted certain policies incorporating the
standards of Rule 17e-1 issued by the Securities and Exchange Commission under
the 1940 Act which requires that the commissions paid to the Distributor and
other affiliates of the Fund must be reasonable and fair compared to the
commissions, fees or other remuneration received or to be received by other
brokers in connection with comparable transactions involving similar

                                      -10-
<PAGE>
 
securities during a comparable period of time. The Rule and procedures also
contain review requirements and require the Manager to furnish reports to the
Board of Trustees and to maintain records in connection with such reviews. After
consideration of all factors deemed relevant, the Board of Trustees will
consider from time to time whether the advisory fee will be reduced by all or a
portion of the brokerage commission given to affiliated brokers.

              ADDITIONAL INFORMATION REGARDING SHARES AND RIGHTS

     The Fund is a non-diversified, open-end investment company established
under Massachusetts law by an Agreement and Declaration of Trust ("Trust
Agreement") dated August 10, 1990, and is the type of organization commonly
known as a "Massachusetts business trust."  It is a series company as
contemplated under Rule 18f-2 under the 1940 Act, having four series of shares
offered at this time which are known as "The Kansas Municipal Fund," "The Kansas
Insured Intermediate Fund", "The Nebraska Municipal Fund" and "The Oklahoma
Municipal Fund."  The Trust Agreement provides that each shareholder, by virtue
of becoming such, will be held to have expressly assented and agreed to the
terms of the Trust Agreement and to have become a party thereto.

     The Trust Agreement permits the Trustees to issue an unlimited number of
full and fractional shares, without par value, from each portfolio.  Each share
of a portfolio represents an equal proportionate interest in the assets and
liabilities belonging to such portfolio with each other share of such portfolio
and is entitled to such dividends and distributions out of the income belonging
to such portfolio as are declared by the Trustees.  The shares do not have
cumulative voting rights nor any preemptive rights.  In case of a liquidation,
subject to the rights of creditors, the holders of shares of each portfolio
being liquidated will be entitled to receive as a series a distribution out of
the net assets belonging only to that portfolio.  Under the Trust Agreement,
expenses attributable to any specific portfolio (whether start-up for a new
portfolio or on-going operating expenses) will be borne by that portfolio.  Any
general expenses of the Fund not readily identifiable as belonging to a
particular portfolio are allocated by or under the direction of the Trustees in
such manner as the Trustees determine to be fair and equitable, usually in
proportion to the portfolio's relative net assets.  The net asset value of the
shares of any portfolio will be computed based only upon the net assets of such
portfolio.

     As a general matter, the Fund will not hold annual or other meetings of the
Fund's shareholders.  This is because the Trust Agreement provides for Fund
shareholders voting only (a) for the election or removal of one or more Trustees
if a meeting is called for that purpose; (b) with respect to any contract as to
which shareholder approval is required by the 1940 Act (such as the Fund's
Management and Investment Advisory Agreement and the Distribution and Services
Agreement); (c) with respect to any termination or reorganization of the Fund or
any portfolio to the extent and as provided in the Trust Agreement; (d) with
respect to any amendment of the Trust Agreement (other than amendments
establishing and designating new portfolios, changing the name of the Fund or
the name of any portfolio, supplying any omission, curing any ambiguity, or
curing, correcting or supplementing any provision thereof which is internally
inconsistent with the 1940 Act or with the requirements of the Internal Revenue
Code and applicable regulations for the Fund to obtain the most 

                                      -11-
<PAGE>
 
favorable treatment thereunder available to regulated investment companies),
which amendments require approval by more than 50% of the shares entitled to
vote; (e) to the same extent as the stockholders of a Massachusetts business
corporation as to whether or not a court action, proceeding or claim should or
should not be brought or maintained derivatively or as a class action on behalf
of the Fund or the shareholders, and (f) with respect to such additional matters
relating to the Fund as may be required by the 1940 Act (such as changes in the
Fund's investment policies and restrictions), the Trust Agreement, the by-laws
of the Fund, or any registration of the Fund with the Securities and Exchange
Commission or any state, or as the Trustees may consider necessary or desirable.

     Each Trustee serves until the next meeting of shareholders, if any, called
for the purpose of considering the election or reelection of such Trustee or of
a successor to such Trustee, and until the election and qualification of his
successor, if any, elected at such meeting, or until such Trustee sooner dies,
resigns, retires or is removed by the shareholders or two-thirds of the
Trustees.

     The Trust Agreement provides that on any matter submitted to a vote of the
shareholders, all Fund shares entitled to vote, irrespective of portfolio, shall
be voted in the aggregate and not by portfolio except that (a) as to any matter
with respect to which a separate vote of any portfolio is required by the 1940
Act, such requirements as to a separate vote by that portfolio shall apply in
lieu of the aggregate voting as described above, and (b) when the Trustees have
determined that the matter affects only the interests of one or more portfolios,
then only shareholders of the affected portfolios shall be entitled to vote
thereon.

     Rule 18f-2 under the 1940 Act provides that any matter required to be
submitted by the provisions of the 1940 Act or applicable state law, or
otherwise, to the holders of the outstanding voting securities of an investment
company with separate portfolios like this Fund shall not be deemed to have been
effectively acted upon unless approved by the holders of a majority of the
outstanding shares (as defined below) of each portfolio "affected by" such
matter.  Rule 18f-2 further provides that a portfolio shall be deemed to be
affected by a matter unless the interests of each portfolio in the matter are
substantially identical or the matter does not affect any interests of such
portfolio.  The Rule specifically exempts the selection of independent auditors,
the approval of principal underwriting contracts and the election of trustees
from such separate voting requirements and specifically provides that any
required approval of the Fund's Management and Investment Advisory Agreement and
the Distribution and Services Agreement is subject to such separate voting
requirements.  In addition, changes in the Fund's investment policies are also
subject to separate voting requirements.

     The Trust Agreement provides that the presence at a meeting of shareholders
in person or by proxy of shareholders entitled to vote at least thirty percent
(30%) of the votes entitled to be cast on a matter (or if voting is to be by
portfolio, shareholders of each portfolio entitled to vote at least thirty
percent (30%) of the votes entitled to be cast by each portfolio) shall
constitute a quorum.  This permits a meeting of shareholders of the Fund to take
place even if less than a majority of the shareholders are present on its
scheduled date.  

                                      -12-
<PAGE>
 
Shareholders would in such a case be permitted to take action which does not
require a larger vote than a majority of a quorum (the election of Trustees and
the ratification of the selection of independent public accountants are
examples). Some matters requiring a larger vote under the Trust Agreement, such
as termination or reorganization of the Fund and certain amendments of the Trust
Agreement, would not be affected by this provision. This is also true with
respect to matters which under the 1940 Act require the vote of a majority of
the outstanding voting shares (as defined below) of the Fund or a particular
portfolio.

     As used in the Prospectus and this Statement of Additional Information, the
term "majority of the outstanding shares" of either the Fund or a particular
portfolio of the Fund means the vote of the lesser of (i) 67% or more of the
shares of the Fund or such portfolio present or represented by proxy at a
meeting, if the holders of more than 50% of the outstanding shares of the Fund
or of such portfolio are present or represented by proxy, or (ii) more than 50%
of the outstanding shares of the Fund or such portfolio.

     Under the terms of the Trust Agreement, a Trustee is liable for his own
willful misfeasance, bad faith, gross negligence or reckless disregard of the
duties involved in the conduct of his office, and for nothing else, and shall
not be liable for errors of judgment or mistakes of fact or of law.  The Trust
Agreement provides for indemnification by the Fund of the Trustees and the
officers of the Fund except with respect to any matter as to which such person
did not act in good faith in the reasonable belief that his action was in or not
opposed to the best interests of the Fund (or the predecessor corporation) but
such person may not be indemnified against any liability to the Fund or the Fund
shareholders to which he would otherwise be subject by reason of willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his office.  The Trust Agreement also provides that
any agreement or undertaking by the Trustees on behalf of the Fund is binding
upon the Fund only and not on the Trustees personally.

                             EXPENSES OF THE FUND

     The Fund's expenses include, among others, management and investment
advisory fees, 12b-1 fees, accounting and administrative fees, taxes, brokerage
fees and commissions, if any, fees of Disinterested Trustees, expenses of
Trustees' and shareholders' meetings, insurance premiums, expenses of redemption
of shares, expenses of issue and sale of shares (to the extent not borne by the
Distributors), expenses of printing and mailing certificates, association
membership dues, charges of the Fund's custodian, and bookkeeping, auditing and
legal expenses, and the fees and expenses of registering the Fund and its shares
with the Securities and Exchange Commission, registering or qualifying its
shares under state securities laws and the expenses of preparing and mailing
prospectuses and reports to shareholders.

                               PERFORMANCE DATA

     As described in the prospectus, the Fund's historical performance may be
shown in the form of "current yield," "tax equivalent yield," "average annual
total return" and "total return" figures.  These various measures of performance
are described below.

                                      -13-
<PAGE>
 
     Current yield is determined in accordance with a standardized method
prescribed by rules of the Securities and Exchange Commission by annualizing net
investment income earned per share for a stated period (normally one month or
thirty days) and dividing the result by the maximum public offering price at the
end of the evaluation period.  The Securities and Exchange Commission's rules
for calculating current yield require the use of certain standardized accounting
practices which are not necessarily consistent with those used by the Fund in
the preparation of its audited financial statements or federal tax return.  The
Fund's current yield figure is based upon historical results and is not
necessarily representative of future performance.

     Tax equivalent yield is determined by dividing that portion of current
yield which is tax-exempt by one minus a stated income tax rate and adding that
portion of current yield, if any, that is not tax-exempt.

     The Fund's distribution return is computed by dividing the income per share
by the number of days in the current month, and the quotient is multiplied by
365.  The result is divided by the offering price per share on the last day of
the month.

     The Fund's average annual total return quotation is computed in accordance
with a standardized method prescribed by rules of the Securities and Exchange
Commission.  The average annual total return for the Fund for a specific period
is found by first taking a hypothetical $1,000 investment ("initial investment")
in the Fund's shares on the first day of the period reduced by the maximum sales
charge in effect on that date and computing the "redeemable value" of that
investment at the end of the period.  The redeemable value is then divided by
the initial investment, and the quotient is taken to the Nth root (N
representing the number of years in the period) and 1 is subtracted from the
result, which is then expressed as a percentage.  The calculation assumes that
all income and capital gains dividends paid by the Fund have been reinvested at
net asset value on the reinvestment dates during the period.

     The Fund's total return quotation is computed by aggregating the percentage
or dollar value change over the period in question, exclusive of the initial
sales charge.

     The Fund's performance figures are based upon historical results and are
not necessarily representative of future performance.  The Fund's shares are
sold at net asset value plus a maximum sales charge of 4.25% of the offering
price.  Returns and net asset value will fluctuate.  Factors affecting the
Fund's performance include general market conditions, operating expenses and
investment management.  Any additional fees charged by a dealer or other
financial services firm would reduce the returns described in this section.
Shares of the Fund are redeemable at net asset value, which may be more or less
than original cost.

NOTES:

The Fund was organized as a business trust under the laws of The Commonwealth of
Massachusetts on August 10, 1990; 87.03 shares of beneficial interest of The
Oklahoma Municipal Fund series of the Ranson Managed Portfolios were issued to
Ranson Capital Corporation, the Fund's investment manager, on _______, 1996 for
$1,000 cash.  The Fund may offer multiple portfolios; currently only four
portfolios are offered.

Organizational expenses are being deferred and will be amortized on a straight-
line basis over a five year period.  If any of the initial shares are redeemed
before the end of the amortization period, the redemption proceeds will be
reduced by the pro rata share of the then unamortized organization expenses.

Item 25.  Persons Controlled by or under Common Control with Registrant.

     Since The Oklahoma Municipal Fund portfolio of Registrant is newly formed

directly or indirectly controlled by or under common control with The Oklahoma
Municipal Fund portfolio of Registrant.

Item 26.  Number of Holders of Securities.

          The Nebraska Municipal Fund:  _____
          The Oklahoma Municipal Fund:    0
                                        _____

Item 27.  Indemnification.

     The following is a summary of the rights of indemnification set forth in
the Agreement and Declaration of Trust of Registrant (see Exhibit 1).  Article
VIII of the Agreement and Declaration of Trust of Registrant provides generally
that any person who is or has been a trustee or officer of Registrant (including
persons who serve at the request of Registrant as directors, trustees or
officers of another organization and including persons who served as officers
and directors of the Registrant) shall be indemnified by Registrant to the
fullest extent permitted by law against liabilities and expenses reasonably
incurred by such person in connection with any claim, suit or proceeding in
which such person becomes involved as a party or otherwise by virtue of being or
having been such a trustee, director or officer and against amounts incurred in
settlement thereof.  It is further provided in such Agreement and Declaration of
Trust that no indemnification shall be provided in the event that it is
determined that such person was engaged in willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of his
office or that such person did not act in good faith in the reasonable belief
that his action was in the best interests of Registrant.  In the event of a
settlement or other disposition not involving a final determination of the
foregoing matters by a court or other body, no indemnification shall be provided
unless such determination is made by a vote of a majority of the "disinterested"

                                      C-2
<PAGE>
 
trustees acting on the matter or a written opinion of independent legal counsel.
The right to indemnification as so provided may be insured against by policies
maintained by the Registrant and shall continue as to any person who has ceased
to be a trustee or officer of Registrant.

     Expenses of preparation and presentation of a defense by a person claiming
indemnification may be advanced by Registrant provided generally that such
person undertakes to repay any such advances if it is ultimately determined that
he is not entitled to indemnification and provided that either such undertaking
is secured by appropriate security or a majority of the "disinterested" trustees
acting on the matter or independent legal counsel in a written opinion
determines that there is reason to believe that such person ultimately will be
found entitled to indemnification.

     The Agreement and Declaration of Trust provides further that in the event
that any shareholder or former shareholder shall be found to be personally
liable solely by reason of his being a shareholder and not because of acts or
omissions of such person, such shareholder shall be entitled out of assets of
the Registrant to be indemnified against all loss and expense arising from such
liability (provided there is no liability to reimburse any shareholder for taxes
paid by reason of such shareholder's ownership of shares or for losses suffered
by reason of any changes in value of any of Registrant's assets).

     The Agreement and Declaration of Trust (Article IV, Section 2(o)) provides
specifically that the trustees have the power to purchase and pay for insurance
out of assets of Registrant as they deem necessary or appropriate for the
conduct of its business including policies insuring shareholders, trustees,
officers, employees, agents, investment managers, principal underwriters or
independent contracts or Registrant against claims or liabilities arising by
reason of such persons holding or having held any such office or position with
Registrant or by reason of any action alleged to have been taken or omitted by
such person in such office or position including any action taken or omitted
that may be determined to constitute negligence whether or not the Registrant
would have the power to indemnify such person against such liability.

     The provisions with respect to indemnification in the Agreement and
Declaration of Trust of Registrant do not affect any rights of indemnification
that persons other than those specifically covered may have whether under
contract or otherwise under law.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to trustees, officers, and controlling persons of the
Registrant pursuant to the provisions of Registrant's Agreement and Declaration
of Trust, or otherwise, Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933 and is, therefore, unenforceable.  In
the event that a claim for indemnification against such liability (other than
the payment by the Registrant of expenses incurred or paid by a trustee, officer
or controlling person of Registrant in the successful defense of any action,
suit or proceeding) as asserted by such trustee, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the 

                                      C-3
<PAGE>
 
question of whether such indemnification by it is against public policy as
expressed in the Securities Act of 1933 and will be governed by the final
adjudication of such issue.
