PROSPECTUS                                                      MAY 1, 1997     

     Montana Tax-Free Fund, Inc. (the "Fund"), is an open-end, non-diversified,
management investment company. The Fund's objective is to provide as high a
level of current income exempt from federal and Montana income taxes as is
consistent with preservation of capital. The Fund will seek to achieve this
objective by investing primarily in tax-exempt securities issued by the State of
Montana and its political subdivisions, agencies, and instrumentalities which
are within the four highest grades of either Moody's Investors Service,Inc., or
Standard & Poor's Corporation or of comparable quality (See"Investment Objective
and Policies.").

     Shares of the Fund are offered with no initial sales charge. A contingent
deferred sales charge is assessed on certain redemptions, however (See
"Contingent Deferred Sales Charge."). See "Distribution Plan" for information
about commissions paid to dealers who sell shares and Fund payments to
compensate for these and other distribution expenses and services.

    
     This Prospectus contains information about the Fund that a prospective
investor should know before investing and should be retained for future
reference. More detailed information concerning the Fund is contained in the
Statement of Additional Information dated May 1, 1997, which has been filed with
the Securities and Exchange Commission and is incorporated into this Prospectus
by reference. A free copy of the Statement of Additional Information may be
obtained by contacting the Fund at the address or telephone number at the top of
the page.

     (1) 4% is the maximum contingent deferred sales charge ("charge") which may
be assessed upon redemption of shares. As more fully explained under "Contingent
Deferred Sales Charge," a charge is assessed, with certain exceptions, against
shares which are redeemed within the first five years of their purchase. The
charge varies from a maximum of 4% for shares which are redeemed within the
first two years, down to 1% for shares redeemed within the fifth year, after
which no further charge is assessed, in accordance with the following schedule:

     (2)  Because the Fund pays 12b-1 fees, long-term shareholders may pay more
in distribution expenses than the economic equivalent of the maximum front-end
sales charges permitted by the NASD.

     (3)  Under the Distribution Agreement, ND Capital, Inc. (the
"Underwriter"), is entitled to a fee, calculated daily and paid monthly, at the
annual rate of 0.75% of the average daily net assets of the Fund. The Fund
incurred a fee of $88,756 for the fiscal year ended December 31, 1996, all of
which was used to partially defray the costs of commissions paid to dealers.

     (4)  Absent the fee waiver, estimated "Total Fund Operating Expenses" would
be 1.29% of average daily net assets on an annualized basis.

     (5)  THE EXAMPLE IS BASED UPON PERCENTAGES IN THE TABLE ABOVE AND SHOULD
NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES
MAY BE GREATER OR LESSER THAN THOSE SHOWN. If the

                                      -2-
<PAGE>
 
fee waivers and expense assumption are removed, the expenses contained in the
example will increase. The Securities and Exchange Commission requires the use
of an assumed 5% annual return. The example assumes the reinvestment of all
dividends and distributions. All dollar figures have been rounded to the nearest
dollar.

                                    SYNOPSIS

                  INVESTMENT OBJECTIVE; PERMITTED INVESTMENTS

     The Fund is an open-end, non-diversified, management investment company.
The Fund's objective is to provide as high a level of current income exempt from
federal and Montana income taxes as is consistent with preservation of capital.
The Fund will seek to achieve this objective by investing primarily in tax-
exempt securities issued by the State of Montana and its political subdivisions,
agencies, and instrumentalities which are within the four highest grades of
either Moody's Investors Service, Inc., or Standard & Poor's Corporation or of
comparable quality. There is no assurance that the Fund's objective will be
achieved. The Fund may also purchase and sell financial futures contracts and
options thereon. See "Investment Objective and Policies" and "Other Investment
Practices."

                       INVESTMENT ADVISER AND UNDERWRITER

     ND Money Management, Inc. (the "Investment Adviser"), has been retained
under an Investment Advisory Agreement to act as the Fund's investment adviser.
The Investment Adviser furnishes the Fund with investment advice and, in
general, supervises the management and investment program of the Fund. Under the
Investment Advisory Agreement, the Fund has agreed to pay the Investment Adviser
an annual fee, payable monthly, of 0.60% of the Fund's average daily net assets.
See "Investment Adviser."

     ND Capital, Inc. (the "Underwriter"), is the Fund's principal underwriter.
See "Purchase of Shares."

                           PURCHASES AND REDEMPTIONS

     Shares may be purchased from investment dealers who have sales agreements
with the Underwriter or from the Underwriter at the public offering price, which
is the net asset value next determined after the Fund receives an order. The
minimum initial investment is $1,000 ($100 for the Monthomatic Investment Plan),
and subsequent investments must be at least $50. See "Purchase of Shares." No
sales charge is imposed when shares are purchased. However, a contingent
deferred sales charge is imposed if certain shares are redeemed within five
years after their purchase. See "Redemption of Shares."

                             INVESTORS IN THE FUND

     The Fund is designed for persons who are seeking a high level of income
exempt from federal and Montana income taxes from a portfolio consisting
primarily of investment grade Municipal Securities. Dividends derived from
earnings of Montana state and local government issues are exempt from Montana
income taxes. Through an investment in shares of the Fund, investors receive the
benefits of professional management and liquidity. In addition, the Fund offers
the economic advantages of block purchases of securities and relief from
administrative details, such as accounting for distributions and the safekeeping
of securities. The Fund's yield and net asset value will fluctuate.

                                   DIVIDENDS

     The Fund declares daily dividends of its net investment income on shares
for which it has received payment. The Fund distributes income dividends monthly
and distributes any net realized short-term and long-term capital gains
annually. Investors may elect to have income and capital gains dividends
automatically reinvested in shares of the Fund. See "Dividends and Taxes."

                    ORGANIZATION; SHARE ATTRIBUTES; MEETINGS

The Fund is organized as a corporation under the laws of the State of North
Dakota and is authorized to issue a total of 200,000,000 shares, all of one
class and one series, with a par value of $.001 per share. Shares are fully paid
and nonassessable when issued, are redeemable and freely transferable, and have
equal rights and preferences in all matters, including voting. There are no
subscription, preemptive, or conversion rights. Regular meetings of shareholders
will not be held unless required under the North Dakota Business Corporation Act
or the Investment Company Act of 1940. Special meetings of shareholders may be
called for any purpose at any time in the manner prescribed under the North
Dakota Business Corporation Act.

                             SPECIAL CONSIDERATIONS

An investment in the Fund is subject to a number of different risks, some of
which are described under "Investment Objective and Policies" and "Other
Investment Practices." As with other mutual funds, there can be no assurance
that the Fund will achieve its objective. In addition, the Fund was organized
recently and has had only a brief history of operations.

                        GENERAL DESCRIPTION OF THE FUND

                        ORGANIZATION AND CLASSIFICATION

     The Fund is an open-end, non-diversified, management investment company,
which is a type of company commonly known as a "mutual fund." The Fund was
incorporated under the laws of the State of North Dakota on April 15, 1993.

                                      -5-
<PAGE>
 
                       INVESTMENT OBJECTIVE AND POLICIES

     The Fund's investment objective is to provide as high a level of current
income exempt from federal and Montana income taxes as is consistent with the
preservation of capital. There are market and investment risks with any
security, and the value of an investment in the Fund will fluctuate over time.
Normally, the value of the Fund's investments will vary inversely with changes
in interest rates. There can be no assurance that the Fund's objective will be
achieved.

     The Fund will seek to achieve its objective by investing in a portfolio of
obligations issued by or on behalf of states, territories, and possessions of
the United States and the District of Columbia and their political subdivisions,
agencies, and instrumentalities, the interest from which is exempt from federal
income taxes ("Municipal Securities"). The Fund may also purchase and sell
financial futures contracts and options thereon, which may produce taxable
capital gains, in connection with attempts to hedge its portfolio investments
and not for speculation.

     The Fund will generally invest substantially all of its assets in
securities on which the interest is exempt from both federal and Montana income
taxes. Under normal circumstances, the Fund will invest at least 65% of its
total assets in obligations of the State of Montana and its political
subdivisions, agencies, and instrumentalities. As a matter of fundamental
policy, the Fund will, under normal market conditions, invest at least 80% of
its net assets in Municipal Securities which generate interest that is not
subject to the alternative minimum tax. All of the Fund's assets will consist of
(1) Municipal Securities which are rated at the time of purchase within the four
highest grades of either Moody's Investors Service, Inc. (Aaa, Aa, A, or Baa),
or Standard & Poor's Corporation (AAA, AA, A, or BBB) or which are unrated but,
as determined by the Investment Adviser, are of comparable quality, (2)
temporary investments in high quality taxable short-term, fixed income
investments, as described in the paragraph which follows and in the Statement of
Additional Information under "Temporary Investments," (3) financial futures and
options thereon as described under "Other Investment Practices," and (4) cash.
Municipal Securities within the four highest grades of Moody's and Standard &
Poor's are generally considered to be "investment grade." Those rated Baa by
Moody's and BBB by Standard & Poor's (and equivalent for unrated securities) may
have speculative characteristics, and changes in economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than is the case with higher grade bonds. The Fund will
promptly dispose of a bond whose rating drops below investment grade or is
reduced in credit quality with respect to unrated securities. The
characteristics of the rating categories are described in the Statement of
Additional Information under "Appendix-Ratings of Investments." As indicated
under "Dividends and Taxes,'' the Fund may invest in "private activity" bonds.
The Fund may also purchase participation interests in Municipal Securities from
various financial institutions, including banks, insurance companies, and 
broker-dealers.

     For temporary defensive purposes, the Fund may invest in any of the
following short-term, fixed income obligations, the interest on which is subject
to federal income taxes: obligations of the United States Government, its
agencies, or instrumentalities; debt securities rated within the three highest
grades of Moody's Investors Service, Inc., or Standard & Poor's Corporation;
commercial paper rated in the highest two grades by either of those rating
services (P-1, P-2, or A-1, A-2, respectively); certificates of deposit of
domestic banks with assets of $25 million or more; and Municipal Securities or
any of the foregoing temporary investments subject to short-term repurchase
agreements. When the Fund invests in accordance with this policy, it may do so
without any percentage limitations.

     The two principal classifications of Municipal Securities are "general
obligation" and "revenue" bonds. 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 only from the revenues 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. 

                                      -6-
<PAGE>
 
Industrial development bonds that are Municipal Securities are in most cases
revenue bonds and do not generally involve the pledge of the credit of the
issuer of such bonds. There are, of course, variations in the degree of risk of
Municipal Securities, both within a particular classification and between
classifications, depending upon numerous factors. See "Municipal Securities" in
the Statement of Additional Information.

     The average weighted maturity of the Fund's debt securities is expected to
range between 15 and 25 years.

     Any policy or restriction which involves a maximum percentage of securities
or assets will not be considered to be violated unless an excess over the
percentage occurs immediately after, and is caused by, an acquisition of
securities or assets of, or borrowing by, the Fund. Changes due to market action
will not cause a violation of a policy or restriction.

     The Fund will not normally engage in the trading of securities for the
purpose of realizing short-term profits, but it will adjust its portfolio as
considered advisable in view of prevailing or anticipated market conditions and
the Fund's investment objective. Accordingly, the Fund may sell portfolio
securities in anticipation of a rise in interest rates and purchase securities
in anticipation of a decline in interest rates. In addition, a security may be
sold and another of comparable quality purchased at approximately the same time
to take advantage of what the Investment Adviser 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, such as changes
in the overall demand for or supply of various types of Municipal Securities or
changes in the investment objectives of some investors. Frequency of portfolio
turnover will not be a limiting factor should the Investment Adviser deem it
desirable to purchase or sell securities.

     The Fund has adopted certain investment restrictions which are presented in
the Statement of Additional Information and which, together with the investment
objective and policies of the Fund, cannot be changed without approval by
holders of a majority of its outstanding shares. As defined in the Investment
Company Act of 1940, this means the lesser of the vote of (a) 67% of the
outstanding shares of the Fund present at a meeting where more than 50% of the
outstanding shares are present in person or by proxy; or (b) more than 50% of
the outstanding shares of the Fund.

     Because Montana's economy is primarily dependent upon agriculture, mining,
and the processing of minerals and agricultural/forest products, various factors
which influence these segments, such as weather conditions, regulatory policies,
world prices, the value of the dollar, and international relations, could affect
the ability of issuers of Montana Municipal Securities to make interest and
principal payments.

                           OTHER INVESTMENT PRACTICES

FINANCIAL FUTURES TRANSACTIONS

     The Fund may engage in various interest rate hedging transactions using
financial instruments with a high degree of correlation to the fixed-income
securities which the Fund may purchase for its portfolio, including interest
rate futures contracts in such financial instruments (e.g., futures contracts in
U.S. Treasury securities) and interest rate related indices (municipal bond
indices) and put and call options on such futures contracts and on such
financial instruments. Financial futures contracts are commodity contracts that
obligate the long or short holder to take or make delivery of a specified
quantity of a financial instrument, such as a security, or the cash value of a
securities index during a specified future period at a specified price. A "sale"
of a futures contract means the undertaking of a contractual obligation to
deliver the securities or the cash value of an index called for by the contract
at a specified price during a specified delivery period. A "purchase" of a
futures contract means the undertaking of a contractual obligation to acquire
the securities or cash value of an index at a specified price during a specified
delivery period. Although some financial futures contracts call for making or
taking 

                                      -7-
<PAGE>
 
delivery of the underlying securities, in most cases these obligations are
closed out before delivery. The closing of such a contractual obligation is
accomplished by purchasing or selling an identical offsetting futures contract.
Such a transaction cancels the obligation under the original contract to make or
take delivery. Other financial futures contracts, such as futures contracts on a
securities index, by their terms call for cash settlements.

     At the time the Fund enters into a futures contract, it is required to
deposit with its Custodian a specified amount of cash or eligible securities
called "initial margin." The initial margin required for a futures contract is
set by the exchange on which the contract is traded. Subsequent payments, called
"variation margin," to and from the broker are made on a daily basis as the
market price of the futures contract fluctuates.

     The Fund may engage in financial futures transactions as an attempt to
hedge against the effects of fluctuations in interest rates and other market
conditions. For example, if the Fund owned long-term Municipal Securities and
interest rates were expected to rise, it could sell futures contracts on a
Municipal Securities Index. If interest rates did increase, the value of the
Municipal Securities in the Fund would decline, but this decline would be offset
in whole or in part by an increase in the value of the Fund's futures contracts.
If, on the other hand, long-term interest rates were expected to decline, the
Fund could hold short-term Municipal Securities and benefit from the income
earned by holding such securities, while at the same time the Fund could
purchase futures contracts on a Municipal Securities Index. Thus, the Fund could
take advantage of the anticipated rise in the value of long-term Municipal
Securities without actually buying them. The futures contracts and short-term
Municipal Securities could then be liquidated and the cash proceeds used to buy
long-term Municipal Securities.

     There are risks associated with the use of financial futures contracts,
because there may be an imperfect correlation between the price movements of
the futures contracts and price movements of the securities which the Fund owns
or intends to purchase. The Fund could lose money on the financial futures
contracts and also on the price of such securities. The degree of difference in
price movements between futures contracts and the securities being hedged
depends upon such things as variations in speculative market demand for futures
contracts and debt securities and differences between the securities being
hedged and the securities underlying the futures contracts, e.g., interest
rates, tax status, maturities, and creditworthiness of issuers. While interest
rates on taxable securities generally move in the same direction as interest
rates on Municipal Securities, there are frequently differences in the rate of
such movements and temporary dislocations. Accordingly, the use of a financial
futures contract on a taxable security or a taxable securities index may involve
a greater risk of an imperfect correlation between the price movements of the
futures contract and of the Municipal Security being hedged than when using a
financial futures contract on a Municipal Security or a Municipal Securities
Index. If a liquid secondary market did not exist when the Fund wished to close
out a financial futures contract, it would not be able to do so and would have
to continue making daily cash payments of variation margin in the event of
adverse price movements. If the Investment Adviser's judgment about the general
direction of interest rates or markets is wrong, the overall performance will be
poorer than if no such contracts had been used. The costs incurred in connection
with futures transactions would also reduce the Fund's yield. In addition,
futures markets have daily market price movement limits for many futures
contracts which may further inhibit the Investment Adviser's ability to manage
the Fund's portfolio. Futures contracts held by the Fund may be illiquid during
periods when daily market price movement limits have been reached. As a result,
net assets of the Fund may be impacted negatively until normal futures trading
resumes or until the Fund's futures contracts are closed out. Finally, certain
provisions of Subchapter M of the Internal Revenue Code restrict the use of
futures contracts and options techniques. See "Taxes" in the Statement of
Additional Information.

     The Fund may also purchase and write call and put options on financial
futures contracts in an attempt to hedge against the effects of fluctuations in
interest rates and other market conditions. A call option gives the purchaser
the right to buy, and the writer the obligation to sell, the underlying futures
contract at the exercise price 

                                      -8-
<PAGE>
 
during the option period. A put option gives the purchaser the right to sell,
and the writer the obligation to buy, the underlying futures contract at the
exercise price during the option period. Upon exercise, the writer (seller) of
the option delivers the futures contract to the holder (buyer) at the exercise
price. An option purchased by the Fund may expire worthless in which case the
Fund would lose the premium paid for it.

     The Fund may engage in futures transactions only on commodities or
securities exchanges or boards of trade. The Fund will not engage in
transactions in financial futures contracts or related options for speculation,
but only as an attempt to hedge against changes in interest rates or market
conditions affecting the values of securities which the Fund owns or intends to
purchase. Although the successful use of futures contracts and options
techniques requires skills different from those needed to select portfolio
securities, the Investment Adviser has experience in the use of these
techniques.

     To the extent necessary to comply with Securities and Exchange Commission
Release No. 10666, when purchasing a futures contract, writing a put option, or
entering into a delayed delivery purchase, the Fund will maintain in a
segregated account with its Custodian cash or liquid high-grade debt securities
equal to the value of such contracts. The amount held by the Custodian is less
than the amount held by any futures commission agent as initial margin and will
be marked to market daily.

DELAYED DELIVERY TRANSACTIONS

     The Fund may purchase portfolio securities on a when-issued or delayed
delivery basis. When-issued or delayed delivery transactions involve a
commitment by the Fund to purchase securities with payment and delivery to take
place in the future in order to secure what is considered to be an advantageous
price or yield to the Fund at the time of entering into the transaction. The
value of fixed income securities to be delivered in the future will fluctuate as
interest rates vary. Because the Fund is required to segregate cash or liquid
high-grade debt securities to satisfy its commitments to purchase when-issued or
delayed delivery securities, management of the Fund's investments may be limited
if commitments to purchase when-issued or delayed delivery securities were to
exceed 25% of the value of its total assets.

     To the extent the Fund engages in when-issued or delayed delivery
purchases, it will do so for the purpose of acquiring portfolio securities
consistent with the Fund's investment objective and policies and not for the
purpose of investment leverage or to speculate in interest rate changes. The
Fund will only make commitments to purchase securities on a when-issued or
delayed delivery basis with the intention of actually acquiring the securities,
but the Fund reserves the right to sell these securities before the settlement
date if deemed advisable.

BORROWING

     The Fund may borrow money for temporary or emergency purposes and then only
in amounts not exceeding the lesser of 10% of its total assets valued at cost or
5% of its total assets valued at market, and, in any event, only if immediately
thereafter there is an asset coverage of at least 300%. The Fund will not
purchase portfolio securities when outstanding borrowings exceed 5% of total
assets. Interest paid on borrowed funds will decrease the net earnings of the
Fund. The Fund may mortgage, pledge, or hypothecate its assets in an amount not
exceeding 10% of its total assets to secure temporary or emergency borrowing.
The policies set forth in this paragraph are fundamental and may not be changed
without the approval of a majority of the Fund's shares.

PORTFOLIO TURNOVER

     The portfolio turnover rate of the Fund is not expected to exceed 100%
annually, but on occasions when there are substantial adjustments in the
portfolio brought about by market conditions, such as significant changes in
interest rates, the portfolio turnover rate may be higher. A 100% annual
portfolio turnover rate would occur, for example, if all the investments in the
Fund's portfolio (exclusive of securities with less than one year to 

                                      -9-
<PAGE>
 
maturity) were replaced once in a period of one year. Higher portfolio turnover
(100% or more) rates may result in increased expenses and taxable capital gains.

DIVERSIFICATION AND CONCENTRATION POLICIES

     The Fund is a non-diversified investment company under the Investment
Company Act of 1940. This means that more than 5% of the Fund's assets may be
invested in the obligations of any issuer. Inasmuch as a relatively high
percentage of the Fund's assets may be invested in the obligations of a limited
number of issuers, the Fund's portfolio securities may be more susceptible to
any single economic, political, or regulatory occurrence than the portfolio
securities of a diversified investment company.

     Because of the relatively small number of issuers of Montana Municipal
Securities, the Fund is more likely to invest a higher percentage of its assets
in the securities of a single issuer than an investment company which invests in
a broad range of tax-exempt securities. This practice involves an increased risk
of loss to the Fund if the issuer is unable to make interest or principal
payments or if the market value of such securities declines.

     The Fund will not invest 25% or more of its total assets in any industry.
Governmental issuers of Montana Municipal Securities are not considered part of
any "industry." However, Montana Municipal Securities backed only by the assets
and revenues of non-governmental users will for this purpose be deemed to be
issued by such non-governmental users, in which case the 25% limitation would
apply to such obligations. Accordingly, no more than 25% of the Fund's assets
will be invested in obligations deemed to be issued by non-governmental users in
any one industry and in taxable obligations of issuers in the same industry. In
addition, the Fund may invest more than 25% of its net assets in industrial
development bonds whose revenue sources are from similar types of projects, for
example, education, electric utilities, health care, housing, transportation, or
water, sewer, and gas utilities. There may be economic, business, or political
developments or changes that affect all securities of a similar type, such as
proposed legislation affecting the financing of certain projects, shortages or
price increases of necessary materials, or declining market needs for such
projects. Therefore, developments affecting a single issuer, industry, or
securities financing similar types of projects could have a significant effect
on the Fund's performance.

SPECIAL CONSIDERATIONS

     An investment in the Fund is subject to a number of different risks, some
of which are described under "Investment Objective and Policies" and "Other
Investment Practices." As with other mutual funds, there can be no assurance
that the Fund will achieve its objective. In addition, the Fund was organized
recently and has had only a brief history of operations.

million.

                                    EXPENSES

     The expenses of the Fund are deducted from its total income before
dividends are paid. These expenses include, but are not limited to,
organizational expenses; taxes; interest; brokerage fees and commissions, if
any; fees and expenses of directors and officers of the Fund who are not
officers or directors of the Investment Adviser; Securities and Exchange
Commission fees and state securities laws fees; charges of custodians and
transfer and dividend disbursing agents; insurance premiums; outside auditing
and legal expenses; costs of maintenance of the Fund's existence; costs
attributable to investor services, including, without limitation, telephone and
personnel expenses; costs of preparing and printing prospectuses and statements
of additional information for regulatory purposes and for distribution to

shareholders of the Fund and of the officers and Board of Directors of the Fund;
and any extraordinary expenses. In addition, the Fund pays distribution fees
pursuant to the terms of a Distribution Plan adopted under Rule 12b-1 of the
Investment Company Act of 1940.

     For the fiscal year ended December 31, 1996, total expenses amounted to
1.29% of average net assets on an annualized basis. Net expenses (after expense
assumption by ND Holdings, Inc., the Fund's sponsor) for the same period
amounted to 0.96% of average net assets on an annualized basis.

                             PORTFOLIO TRANSACTIONS

     The Investment Adviser may consider a number of factors in determining
which brokers to use for the Fund's portfolio transactions. These factors
include, but are not limited to, research services, reasonableness of
commissions, quality of services and execution, and sales of Fund shares. For
further details, see "Portfolio Transactions" in the Statement of Additional
Information.

     In effecting purchases and sales of the Fund's portfolio securities, the
Investment Adviser and the Fund may place orders with and pay brokerage
commissions to brokers which are affilliated with the Fund, the Investment
Adviser, the Distributor or selected dealers participating in the offering of
the Fund's shares. Subject to rules adopted by the Securities and Exchange
Commission, the Fund may also purchase municipal securities from other members
of underwriting syndicates of which the Underwriter or other affiliates of the
Fund are members.

                                     SHARES

                                SHARE ATTRIBUTES

     The Fund is authorized to issue a total of 200,000,000 shares, all of one
class and one series, with a par value of $.001 per share. All shares, when
issued, are fully paid and non-assessable and are redeemable and freely
transferable. All shares are common shares and have equal rights and preferences
in all matters, including voting. Cumulative voting, a form of proportional
representation, is permitted in the election of directors. Under cumulative
voting, a shareholder may cumulate votes either by casting for one candidate a
number of votes equal to the number of directors to be elected multiplied by the
number of votes represented by the shares entitled to vote or by distributing
all of those votes on the same principle among any number of candidates. There
are no subscription, preemptive, or conversion rights.

                              SHAREHOLDER MEETINGS

     It is probable that the Fund will not hold regular meetings of
shareholders. The Fund's Bylaws provide that regular meetings of shareholders
may be held on an annual or other less frequent basis but need not be held
unless required by law. Under the North Dakota Business Corporation Act, if a
regular meeting of shareholders has not been held during the immediately
preceding fifteen months, a shareholder or shareholders holding 5% or more of
the voting power of all shares entitled to vote may demand a regular meeting by
written notice of demand given to the president or secretary of the Fund. Within
thirty days after receipt of the demand, the Board of Directors must cause a
regular meeting of shareholders to be called, or if the Board fails to do so,
the shareholder or shareholders making the demand may call the meeting by giving
notice as prescribed by law. All necessary expenses of the notice and the
meeting must be paid by the Fund.

     In addition to regular meetings, special meetings of shareholders may be
called for any purpose at any time in the manner prescribed under the North
Dakota Business Corporation Act. Meetings of shareholders will also be held
whenever required in order to comply with the Investment Company Act of 1940;
however, the Fund does not intend to hold annual shareholder meetings.
Shareholders have the right to remove directors.

                              DIVIDENDS AND TAXES

DIVIDENDS

     All the net investment income of the Fund is declared daily as a dividend
on shares for which the Fund has received payment. Net investment income of the
Fund consists of all interest income earned on portfolio assets less all
expenses of the Fund. Income dividends will be distributed monthly, and
dividends of net realized short-

                                      -12-
<PAGE>
 
term and long-term capital gains, if any, will normally be paid out once a year
after the end of the Fund's fiscal year. The Fund may at any time vary the
foregoing dividend practices and, therefore, reserves the right from time to
time to either distribute or retain for reinvestment such of its net investment
income and its net short-term and long-term capital gains as the Board of
Directors of the Fund determines appropriate under the then current
circumstances. In particular, and without limiting the foregoing, the Fund may
make additional distributions of net investment income or capital gain net
income in order to satisfy the minimum distribution requirements contained in
the Internal Revenue Code (the "Code").

     Income and capital gain dividends, if any, will be credited to shareholder
accounts in full and fractional Fund shares at net asset value on the
reinvestment date, except that upon written request to the Transfer Agent, a
shareholder may select one of the following options:

     (1)  To receive income dividends in cash and capital gain dividends in
          shares at net asset value;

     (2)  To receive both income and capital gain dividends in cash; or
     
     (3)  To receive both income and capital gain dividends in shares of
          Integrity Fund of Funds, Inc. ("Integrity"), at net asset value. If
          you select this option, you must first open a new account with
          Integrity with a minimum investment of $100.

     Cash dividends and reinvested dividends will be paid or reinvested, as the
case may be, on the last day of the month. Share certificates are issued only
for full shares and only upon a request by the shareholder to the Transfer
Agent.

TAXES

     The Fund intends to qualify as a regulated investment company under
Subchapter M of the Code and, if so qualified, will not be liable for federal
income taxes to the extent its earnings are distributed. The Fund intends to
meet the requirements of the Code applicable to regulated investment companies
distributing tax-exempt interest dividends, and, therefore, dividends
representing net interest received on Municipal Securities will not be
includable by shareholders in their gross income for federal income tax
purposes, except to the extent such interest is subject to the alternative
minimum tax as discussed hereinafter. Dividends representing taxable net
investment income (such as net interest income from temporary investments in
obligations of the United States), net short-term capital gains, and gains on
the sale of market discount bonds purchased after April 30, 1993, if any, are
taxable to shareholders as ordinary income, and long-term capital gain dividends
are taxable to shareholders as long-term capital gains, regardless of how long
the shares have been held and whether received in cash or shares. Long-term
capital gain dividends received by individual shareholders whose marginal rate
on ordinary income is at least 31% are taxed at a maximum federal rate of 28%.
Dividends declared by the Fund in October, November, or December to shareholders
of record as of a date in one of those months and paid before the following
January are treated as paid on December 31 of the calendar year declared for
federal income tax purposes. All taxpayers are required to disclose on their
federal income tax returns the amount of tax-exempt interest earned during the
year, including exempt-interest dividends from the Fund.

     A capital gains dividend received shortly after the purchase of shares
reduces the net asset value of the shares by the amount of the dividend and,
although in effect a return of capital, will be taxable to the shareholder. If
the net asset value of shares were reduced below the shareholder's cost by
dividends representing gains realized on sales of securities, such dividends
would be a return of investment though taxable as stated above. In addition,
shareholders may lose the tax-exempt status on accrued income if shares are
redeemed before a dividend is declared.

     Net interest on certain "private activity bonds" issued on or after August
8, 1986, is treated as an item of tax preference and may, therefore, be subject
to both the individual and corporate alternative minimum tax. To the extent
provided by regulations to be issued by the Secretary of the Treasury, exempt-
interest dividends from the

                                      -13-
<PAGE>
 
Fund are to be treated as interest on "private activity bonds" in proportion to
the interest the Fund receives from private activity bonds, reduced by allowable
deductions.

     Exempt-interest dividends, except to the extent of interest from "private
activity bonds," are not treated as a tax preference item. For a corporate
shareholder, however, such dividends will be included in determining such
corporate shareholder's "adjusted current earnings." Seventy-five percent of the
excess, if any, of "adjusted current earnings" over the corporate shareholder's
alternative minimum taxable income with certain adjustments will be a tax
preference item. Corporate shareholders are advised to consult their tax
advisers with respect to alternative minimum tax consequences.

     Individuals whose modified income exceeds a base amount will be subject to
federal income tax on up to 85% of their Social Security benefits. Modified
income includes adjusted gross income, one-half of Social Security benefits, and
tax-exempt interest, including exempt-interest dividends from the Fund.

     Dividends to the extent of interest received on Montana state and local
government issues are exempt from Montana state income taxes. Distributions
which are categorized as long-term capital gains for federal income tax purposes
will generally receive the same treatment under Montana law. However, dividends
from the Fund are not exempt to corporations which are shareholders of the Fund
under Montana law. Corporations are advised to consult their own tax advisers in
that regard.

     The Fund is required by law to withhold 31% of taxable dividends and
redemption proceeds paid to certain shareholders who do not furnish a correct
taxpayer identification number (in the case of individuals, a Social Security
number) and in certain other circumstances.

     After each transaction, shareholders will receive a confirmation statement
giving complete details of the transaction. In addition, the statement will show
the details of prior transactions in the account during the calendar year.
Information for federal income tax purposes will be provided after the end of
the calendar year.

                                NET ASSET VALUE

     The net asset value per share is determined by calculating the total value
of the Fund's assets, which will normally be composed mainly of investment
securities, deducting total liabilities, and dividing the result by the number
of shares outstanding. Fixed income securities are valued by using market
quotations or independent pricing services that use prices provided by market
makers or estimates of market values obtained from yield data relating to
instruments or securities with similar characteristics. Financial futures are
valued at the settlement price established each day by the board of trade or
exchange on which they are traded. Other securities and assets are valued at
fair value as determined in good faith by the Board of Directors. If an event
were to occur, after the value of an instrument was so established but before
the net asset value per share was determined, which was likely to materially
change the net asset value, then that instrument would be valued using fair
value considerations by the Board of Directors or its delegates. On each day the
New York Stock Exchange is open for trading, the net asset value is determined
as of the close of the Exchange (normally, 3:00 p.m. Minot, North Dakota, time).


                               PURCHASE OF SHARES

                              GENERAL INFORMATION

     The Fund's principal underwriter is ND Capital, Inc. (the "Underwriter"), 1
North Main, Minot, North Dakota 58703. Shares may be purchased from investment
dealers who have sales agreements with the Underwriter or from the Underwriter
at the public offering price, which is the net asset value next determined after
the Fund

                                      -14-
<PAGE>
 
receives an order. If you do not have a dealer, the Fund can refer you to one.
The minimum initial investment is $1,000 ($100 for the Monthomatic Investment
Plan), and the minimum subsequent investment is $50, but such minimum amounts
may be changed at any time in the Fund's discretion. 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. The Fund allocates net interest income to those shares for which the
Fund has received payment. The Fund receives the entire public offering price of
all shares sold.

     Orders for the purchase of shares will be confirmed at a price based on the
net asset value next determined after receipt of the order by the Fund. However,
orders received by dealers prior to the determination of net asset value (See
"Net Asset Value.") and received by the Fund prior to the close of its business
day will be confirmed at a price based on the net asset value effective on that
day. Dealers are obligated to transmit orders promptly.

     No sales charge is imposed when shares are purchased. However, a contingent
deferred sales charge is imposed if certain shares are redeemed within five
years after their purchase. See "Redemption of Shares." The Underwriter will pay
a sales commission to investment dealers and to its salesmen who sell Fund
shares. The Underwriter may also provide additional promotional incentives to
dealers who sell Fund shares. In some instances, these incentives may be offered
only to certain dealers who have sold or may sell significant amounts of shares.

     The Fund reserves the right to withdraw all or any part of the offering
made by this Prospectus and to reject purchase orders. Also, from time to time,
the Fund may temporarily suspend the offering of its shares to new investors.
During the period of such suspension, persons who are already shareholders of
the Fund normally will be permitted to continue to purchase additional shares
and to have dividends reinvested.

     In order to facilitate redemptions and to eliminate the need for
safekeeping, the Transfer Agent will not issue certificates for shares unless
requested to do so. A shareholder may obtain a certificate by writing to the
Transfer Agent at the address on the back cover of the Prospectus.

     Shareholders should direct their inquiries to the Fund at the address and
telephone number shown on the cover page of the Prospectus or to the investment
dealer from which they received the Prospectus.

     Robert E. Walstad and Peter A. Quist, who are directors and the president
and treasurer and vice president and secretary, respectively, of the Fund, are
also the only two directors and officers of the Underwriter. The Underwriter is
a subsidiary of ND Holdings, Inc., a North Dakota corporation.

                          MONTHOMATIC INVESTMENT PLAN

     A shareholder may purchase additional Fund shares through an automatic
investment program. With the Monthomatic Investment Plan ("Monthomatic"),
monthly investments (minimum $50) are made automatically from the shareholder's
account at a bank, savings and loan association, or credit union into the
shareholder's Fund account. By enrolling in Monthomatic, the shareholder
authorizes the Fund and its agents to either draw checks or initiate Automated
Clearing House debits against the designated account at a bank or other
financial institution. Such account must have check or draft writing privileges.
This privilege may be selected by completing the appropriate section on the
Account Application or by contacting the Underwriter for appropriate forms.

     A shareholder may terminate the Plan by sending written notice to the
Transfer Agent at the address shown on the back cover of the Prospectus.
Termination by a shareholder will become effective within 7 days after the

                                      -15-
<PAGE>
 
Transfer Agent has received the request. The Fund may immediately terminate a
shareholder's Plan in the event that any item is unpaid by the shareholder's
financial institution. The Fund may terminate or modify this privilege at any
time.

                               DISTRIBUTION PLAN

     Although Fund shares are sold without an initial sales charge, the
Underwriter pays a sales commission equal to 33 1/4% (1% on sales of $1 million
or more) of the amount invested to dealers who sell shares (excluding sales to
investors exempt from the contingent deferred sales charge). As a further
inducement to the sale of Fund shares and in recognition of services provided to
shareholders, the Underwriter may also make commission payments to dealers at
the annual rate of up to 0.25% of the average net assets (computed as described
under "Net Asset Value") which are attributable to shareholders of the Fund for
whom such dealers are designated as the dealers of record. Among the various
services which dealers provide shareholders are giving investment advice with
respect to the Fund on an ongoing basis, assisting in redeeming shares,
interpreting confirmations, statements, and other documents, and communicating
with the Fund and its Transfer Agent and Custodian.

     To compensate the Underwriter for its services and expenses in distributing
shares, including the foregoing payments, the Fund has adopted a Distribution
Plan (the "Plan") pursuant to Rule 12b-1 under the Investment Company Act of
1940. The Plan provides for monthly payments by the Fund to the Underwriter at
the annual rate of 0.75% of the average daily net assets of the Fund. The Plan
must be approved annually by the Fund's Board of Directors and may be terminated
at any time by a majority vote of the directors who are not "interested persons"
of the Fund and have no direct or indirect financial interest in the operation
of the Plan or in the Distribution Agreement or in any other agreement related
to the Plan (the "Qualified Directors") or by vote of a majority of the
outstanding shares of the Fund. If the Plan is terminated and not continued, the
Underwriter is not legally entitled to any payments for amounts expended but not
yet recovered. However, the Fund's Board of Directors reserves the right to make
payments to the Underwriter notwithstanding a termination or non-continuance.
The Plan may not be amended so as to increase materially the amount of the fee
unless approved by a vote of at least a majority of the outstanding shares of
the Fund. In addition, no material amendment to the Plan may be made unless
approved by the Fund's Board of Directors. In addition to reimbursing the
Underwriter for commissions previously paid to dealers and related financing
costs (together with amounts received from contingent deferred sales charges),
the Plan also provides the Underwriter with reasonable compensation for its
services and other expenses. Other expenses incurred by the Underwriter may
include allocable overhead expenses, such as salaries, rent, printing, and
communications.

     During periods of substantial sales of shares, the commissions paid by the
Underwriter to dealers may, together with other distribution expenses, exceed
the amount of Plan payments it receives. This is likely to be the case in the
early years of the Fund's operations. In other periods, the payments under the
Plan may exceed the amount of commissions and other distribution expenses paid
by the Underwriter, which has the effect of reimbursing the Underwriter for
distribution expenses incurred in prior periods. Payments made to the
Underwriter under the Plan are not dependent upon expenses incurred, and in any
given year the Underwriter may have fewer expenses than the amount of the
payments, thus creating a "profit."

                              EXCHANGE PRIVILEGE

     By contacting the Transfer Agent, a shareholder may exchange some or all of
his shares in any of the funds underwritten by NDCapital, Inc. or Ranson Capital
Corporation at net asset value, subject to these conditions: (1) The length of
time of the investment will be carried forward to the Fund. (2) If you paid a
front-end sales charge, no contingent deferred sales charge will be imposed in
the event you redeem any or all of your shares. (3) If the original fund is
subject to a contingent deferred sales charge ("CDSC"), the CDSC will be carried
forward into the Fund and will be applied in the event you redeem any or all of
your shares.

                                      -16-
<PAGE>
 
Each exchange involves the redemption of fund shares to be exchanged and the
purchase of Fund shares. As a result, any gain or loss on the redemption of fund
shares exchanged is reportable on the shareholder's federal income tax return.
The exchange privilege may be changed or discontinued upon 60 days' written
notice to shareholders and is available only to shareholders in states where
such exchanges may be legally made. A sharehold considering an exchange should
obtain and read the prospectus of the Fund and consider the differences between
it and the fund whose shares he owns before making an exchange.

For further information on how to excercise the exchange privilege, contact the
Transfer Agent.
                              REDEMPTION OF SHARES

                                  REDEMPTIONS

Any shareholder may require the Fund to redeem shares. When shares are held for
the account of a shareholder by the Fund's Transfer Agent, the shareholder may
redeem them by making a written request with signatures guaranteed to the
Transfer Agent at the address shown on the back cover of the Prospectus. When
certificates for shares have been issued, they must be mailed to or deposited
with the Transfer Agent, along with a duly endorsed stock power with signatures
guaranteed and accompanied by a written request for redemption. Signatures must
be guaranteed by a commercial bank, trust company, savings and loan association,
or member firm of a national securities exchange, and a signature guarantee will
be required before payment is made in connection with a redemption. A notary
public may not provide a signature guarantee. Further documentation may be
requested, and a signature guarantee is always required, from corporations,
custodians (e.g., under the Uniform Transfers to Minors Act), executors,
administrators, trustees, or guardians. The redemption request and stock power
must be signed exactly as the account is registered including any special
capacity of the registered owner. The redemption price will be the net asset
value next determined following receipt of a properly executed request with any
required documents, less any applicable contingent deferred sales charge, as
described below. Payment for shares redeemed will be made in cash as promptly as
practicable but in no event later than seven days after receipt of a properly
executed letter of instructions accompanied by any outstanding share
certificates in proper form for transfer. When the Fund is requested to redeem
shares for which it may not yet have received good payment (e.g., cash or
certified check on a United States bank), it may delay the mailing of a
redemption check until such time as it has assured itself that good payment has
been collected for the purchase of such shares (which will generally be within
15 calendar days).

                       CONTINGENT DEFERRED SALES CHARGE

Except as otherwise provided below, a contingent deferred sales charge
("charge") is imposed only if a shareholder redeems shares purchased within the
preceding five years. Shares acquired by reinvestment of dividends may be
redeemed without charge even though acquired within five years. In addition, a
number of shares having a value equal to any net increase in the value of all
shares purchased by the shareholder during the preceding five years will be
redeemed without a contingent deferred sales charge. Subject to the foregoing
exclusions, the amount of the charge is determined as a percentage of the
redemption proceeds and will depend on the number of years the dollar amount
being redeemed was invested, according to the following table:


                 YEAR SINCE REDEMPTION   PERCENTAGE CONTINGENT
                  AMOUNT WAS INVESTED    DEFERRED SALES CHARGE

                        First................... 4.0%
                        Second.................. 4.0%
                        Third................... 3.0%
                        Fourth.................. 2.0%
                        Fifth................... 1.0%
                        Sixth and following.....No Charge

                                      -17-
<PAGE>
 
     If the initial amount of purchase is $1 million or more, the charge is
reduced to 1% and only applies during the first year of purchase. In addition,
purchases totaling $1 million or more made within 13 months of the initial
purchase date qualify for this exception, provided that the purchaser notifies
the Fund in writing at the time of the initial purchase of his or her intent to
purchase $1 million or more within 13 months and subsequently satisfies this
condition. Any shares purchased and sold within the 13-month period will be
deducted in computing total purchases, and the charge applies for one year after
purchases total a minimum of $1 million.

     All purchases are considered made on the last day of the month of purchase.
In determining whether a contingent deferred sales charge is payable on any
redemption, the Fund will first redeem shares not subject to any charge.
Thereafter, in determining the applicable percentage rate, the amount of dollars
redeemed will be charged against the aggregate cost of shares purchased in each
year, beginning with the shares purchased earliest. This will result in a
shareholder paying the lowest possible contingent deferred sales charge rate.
For an example illustrating the operation of the contingent deferred sales
charge, see "Purchase and Redemption of Shares" in the Statement of Additional
Information.

     The Fund may sell shares without a contingent deferred sales charge to
directors, officers, and employees (including retirees) of the Fund, of ND
Holdings, Inc., of ND Money Management, Inc., and of ND Capital, Inc., for
themselves or their spouses, children, or parents and parents of spouse, or to
any trust, pension, or profit-sharing, or other benefit plan for only such
persons at net asset value and in any amount. The Fund may also sell shares
without a contingent deferred sales charge to broker-dealers having sales
agreements with NDCapital, Inc., and registered representatives and other
employees of such broker-dealers, including their spouses and children; to
financial institutions having sales agreements with NDCapital, Inc., 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.

     ND Capital, Inc., receives the entire amount of any contingent deferred
sales charges assessed.

                            REINSTATEMENT PRIVILEGE

     You may reinvest up to the amount of your redemption proceeds free of all
sales charges. 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. The Fund
reserves the right to modify or terminate this privilege at any time. You will
receive the net asset value per share the day your check arrives at the Fund. If
you were charged a contingent deferred sales charge on your redemption, the
amount you were charged will be reinstated as additional shares upon repurchase
in proportion to the reinvestment amount of your redemption proceeds.

                               PERFORMANCE DATA

     The Fund may publish certain performance figures in advertisements from
time to time. These performance figures may include yield, tax equivalent yield,
and total return figures.

     Yield reflects the income per share deemed earned by the Fund's portfolio
investments. Yield is determined by dividing the net investment income per share
deemed earned during the preceding 30-day period by the offering price per share
on the last day of the period and annualizing the result. Tax equivalent yield
shows the yield from a taxable investment which would produce an after-tax yield
equal to that of a fund that invests in tax-exempt securities. It is computed by
dividing the tax-exempt portion of the Fund's yield (as calculated above) by

                                      -18-
<PAGE>
 
one minus a stated income tax rate and adding the product to the portion (if
any) of the Fund's yield that is not tax-exempt. Yields are calculated according
to accounting methods that are standardized for all stock and bond funds.
Because yield calculation methods differ from the methods used for other
accounting purposes, the Fund's yield may not equal its distribution rate, the
income paid to an investor's account, or the income reported in the Fund's
financial statements.

     Total return is the percentage change in the value of a hypothetical
investment that has occurred in the indicated time period, taking into account
the imposition of various fees, except the contingent deferred sales charge, and
assuming the reinvestment of all dividends and distributions. Cumulative total
return reflects the Fund's performance over a stated period of time. Average
annual total return reflects the hypothetical annually compounded return that
would have produced the same cumulative total return if the Fund's performance
had been constant over the entire period.

     The Fund may also include in advertisements quarterly performance rankings
compiled by independent organizations such as Lipper Analytical Services and
publications which monitor the performance of mutual funds. Performance
information may be quoted numerically or may be represented in a table, graph,
or other illustration.

     All performance figures are based on historical results and are not
intended to indicate future performance. A more detailed description of the
foregoing performance figures and their methods of computation is contained in
the Fund's Statement of Additional Information under CALCULATION OF PERFORMANCE
DATA.

MUNICIPAL SECURITIES

     Municipal Securities (as defined in the Prospectus) are debt obligations
issued to obtain funds for various public purposes, including the construction
of a wide range of public facilities such as airports, bridges, highways,
housing, hospitals, mass transportation, schools, streets, and water and sewer
works. Other public purposes for which Municipal Securities may be issued
include refunding of outstanding obligations, obtaining funds for general
operating expenses, and obtaining funds to loan to other public institutions and
facilities. In addition, certain types of industrial development bonds are
issued by or on behalf of public authorities to obtain funds to provide
privately-operated housing facilities, sports facilities, convention or trade
show facilities, airport, mass transit, port or parking facilities, air or water
pollution control facilities, and certain local facilities for water supply,
gas, electricity, or sewage or solid waste disposal. Such obligations, which may
include lease arrangements, are included within the term Municipal Securities if
the interest paid thereon qualifies as exempt from federal income tax. Other
types of industrial development bonds, the proceeds of which are used for the
construction, equipment, repair, or improvement of privately-operated industrial
or commercial facilities, may constitute Municipal Securities, although the
current federal tax laws place substantial limitations on the size of such
issues.

     The two principal classifications of Municipal Securities are "general
obligation" and "revenue" bonds. 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 only from the revenues 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. Industrial
development bonds that are Municipal Securities are in most cases revenue bonds
and do not generally involve the pledge of the credit of the issuer of such
bonds. There are, of course, variations in the degree of risk of Municipal
Securities, both within a particular classification and between classifications,
depending upon numerous factors.

     The yields on Municipal Securities are dependent upon a variety of factors,
including general money market conditions, general conditions of the Municipal
Securities market, size of a particular offering, maturity of the obligation,
and rating of the issue. The ratings of Moody's Investors Service, Inc., and
Standard & Poor's Corporation represent their opinions as to the quality of the
Municipal Securities which they undertake to rate. It should be emphasized,
however, that ratings are general and are not absolute standards of quality.
Consequently, Municipal Securities with the same maturity, coupon, and rating
may have different yields, while Municipal Securities of the same maturity and
coupon with different ratings may have the same yield.  The Fund will not
purchase or hold more than 5% of its net assets in securities rated below
investment grade.

     The Fund may purchase participation interests in Municipal Securities (such
as industrial development bonds) from financial institutions. A participation
interest gives the Fund an undivided interest in the Municipal Securities in the
proportion that the Fund's participation interest bears to the total principal
amount of the Municipal Securities. These instruments may be variable or fixed
rate.

                                      B-2
<PAGE>
 
     Not more than 5% of the net assets of the Fund will be invested in
participation interests in Municipal Securities during the coming year.

     Provisions of the federal bankruptcy statutes relating to the adjustment of
debts of political subdivisions and authorities of states of the United States
provide that, in certain circumstances, such subdivisions or authorities may be
authorized to initiate bankruptcy proceedings without prior notice to or consent
of creditors, which proceedings could result in material and adverse
modification or alteration of the rights of holders of obligations issued by
such subdivisions or authorities.

     Litigation challenging the validity under state constitutions of present
systems of financing public education has been initiated or adjudicated in a
number of states, and legislation has been introduced to effect changes in
public school finances in some states. In other instances there has been
litigation challenging the issuance of pollution control revenue bonds or the
validity of their issuance under state or federal law which litigation could
ultimately affect the validity of those Municipal Securities or the tax-free
nature of the interest thereon.

TEMPORARY INVESTMENTS

     For temporary defensive purposes, the Fund may invest in any of the
following short-term, fixed-income obligations, the interest on which is subject
to federal income taxes: obligations of the United States Government, its
agencies, or instrumentalities; debt securities rated within the three highest
grades of Moody's Investors Service, Inc., or Standard & Poor's Corporation;
commercial paper rated in the highest two grades by either of those rating
services (P-l, P-2 or A-l, A-2, respectively); certificates of deposit of
domestic banks with assets of $25,000,000 or more; and Municipal Securities or
any of the foregoing temporary investments subject to short-term repurchase
agreements.  When the Fund invests in accordance with this policy, it may do so
without percentage limits.  A repurchase agreement is an instrument under which
the purchaser acquires ownership of a security from a broker-dealer or bank that
agrees to repurchase the security at a mutually agreed upon time and price
(which price is higher than the purchase price), thereby determining the yield
during the holding period.  Maturity of the securities subject to repurchase may
exceed one year.  In the event of a bankruptcy or other default of a seller of a
repurchase agreement, the Fund might incur expenses in enforcing its rights and
could experience losses, including a decline in the value of the underlying
securities and loss of income.  Dividends from interest income from temporary
investments may be taxable to shareholders as ordinary income.  See "Dividends
and Taxes" in the Prospectus.  For a description of the ratings of commercial
paper and other debt securities permitted as temporary investments, see
"Appendix--Ratings of Investments."


                       INVESTMENT POLICIES AND TECHNIQUES

GENERAL

     The Fund may engage in futures transactions in accordance with its
investment objective and policies.  The Fund intends to engage in such
transactions if it appears advantageous to the Investment Adviser to do so in
order to pursue its investment objective, to hedge against the effects

                                      B-3
<PAGE>
 
of fluctuating interest rates, and to stabilize the value of its assets.  The
use of futures, possible benefits, and attendant risks are discussed below,
along with the information concerning certain other investment policies and
techniques.

FINANCIAL FUTURES CONTRACTS

     The Fund may enter into financial futures contracts for the future delivery
of a financial instrument, such as a security, or the cash value of a securities
index.  This investment technique is designed to hedge (i.e., protect) against
anticipated future changes in interest rates or market conditions which
otherwise might adversely affect the value of securities which the Fund holds or
intends to purchase.  A "sale" of a futures contract means the undertaking of a
contractual obligation to deliver the securities or the cash value of an index
called for by the contract at a specified price during a specified delivery
period.  A "purchase" of a futures contract means the undertaking of a
contractual obligation to acquire the securities or cash value of an index at a
specified price during a specified delivery period.  At the time of delivery in
the case of fixed income securities pursuant to the contract, adjustments are
made to recognize differences in value arising from the delivery of securities
with a different interest rate than that specified in the contract.  In some
cases, securities called for by a futures contract may not have been issued at
the time the contract was written.  The Fund will not enter into any futures
contracts or options on futures contracts if the aggregate of the contract value
of the outstanding options written by the Fund would exceed 50% of the total
assets of the Fund.

     Although some financial futures contracts by their terms call for the
actual delivery or acquisition of securities, in most cases the contractual
commitment is closed out before delivery without having to make or take delivery
of the security. The offsetting of a contractual obligation is accomplished by
purchasing (or selling, as the case may be) on a commodities exchange an
identical futures contract calling for delivery in the same month. Such a
transaction, if effected through a member of an exchange, cancels the obligation
to make or take delivery of the securities. All transactions in the futures
market are made, offset, or fulfilled through a clearing house associated with
the exchange on which the contracts are traded. The Fund will incur brokerage
fees when it purchases or sells contracts and will be required to maintain
margin deposits. Futures contracts entail risks. If the Investment Adviser's
judgment about the general direction of interest rates or markets is wrong, the
overall performance may be poorer than if no such contracts had been made.

     There may be an imperfect correlation between movements in prices of
futures contracts and portfolio securities being hedged. In addition, the market
prices of futures contracts may be affected by certain factors. If participants
in the futures market elect to close out their contracts through offsetting
transactions rather than meet margin requirements, distortions in the normal
relationship between the debt securities and futures markets could result. Price
distortions could also result if investors in futures contracts decide to make
or take delivery of underlying securities rather than engage in closing
transactions because of the resultant reduction in the liquidity of the futures
market. In addition, from the point of view of speculators, the margin
requirements in the futures market are less onerous than margin requirements in
the cash market. Thus, increased participation by speculators in the futures
market could cause temporary price distortions. Due to the possibility of

                                      B-4
<PAGE>
 
price distortions in the futures market and because of the imperfect correlation
between movements in the prices of securities and movements in the prices of
futures contracts, a correct forecast of market trends by the Investment Adviser
may still not result in a successful hedging transaction. If this should occur,
the Fund could lose money on the financial futures contracts and also on the
value of its portfolio securities.

OPTIONS ON FINANCIAL FUTURES CONTRACTS

     The Fund may purchase and write call and put options on financial futures
contracts. An option on a futures contract gives the purchaser the right, in
return for the premium paid, to assume a position in a futures contract at a
specified exercise price at any time during the period of the option. Upon
exercise, the writer of the option delivers the futures contract to the holder
at the exercise price. The Fund would be required to deposit with its Custodian
initial margin and maintenance margin with respect to put and call options on
futures contracts written by it. Options on futures contracts involve risks
similar to those risks relating to transactions in financial futures contracts
described above. Also, an option purchased by the Fund may expire worthless, in
which case the Fund would lose the premium paid therefor.

DELAYED DELIVERY TRANSACTIONS

     The Fund may purchase portfolio securities on a when-issued or delayed
delivery basis.  When-issued or delayed delivery transactions involve a
commitment by the Fund to purchase securities with payment and delivery to take
place in the future in order to secure what is considered to be an advantageous
price or yield to the Fund at the time of entering into the transaction.  When
the Fund enters into a delayed delivery purchase, it becomes obligated to
purchase securities and it has all the rights and risks attendant to ownership
of a security, although delivery and payment occur at a later date.  The value
of fixed income securities to be delivered in the future will fluctuate as
interest rates vary.  At the time the Fund makes the commitment to purchase a
security on a when-issued or delayed delivery basis, it will record the
transaction and reflect the amount due and the value of the security in
determining its net asset value.  The Fund generally has the ability to close
out a purchase obligation on or before the settlement date, rather than to
purchase the security.

     To the extent the Fund engages in when-issued or delayed delivery
purchases, it will do so for the purpose of acquiring portfolio securities
consistent with the Fund's investment objective and policies and not for the
purpose of investment leverage or to speculate in interest rate changes. The
Fund will only make commitments to purchase securities on a when-issued or
delayed delivery basis with the intention of actually acquiring the securities,
but the Fund reserves the right to sell these securities before the settlement
date if deemed advisable.

REGULATORY RESTRICTIONS

     To the extent required to comply with Securities and Exchange Commission
Release No. 10666, when purchasing a futures contract, writing a put option, or
entering into a delayed delivery purchase, the Fund will maintain in a
segregated account with its Custodian cash or liquid high-

                                      B-5
<PAGE>
 
grade debt securities equal to the value of such contracts.  The amount held by
the Custodian is less than the amount held by any futures commission agent as
initial margin and will be marked to market daily.

     To the extent required to comply with Commodity Futures Trading Commission
Regulation 4.5 and thereby avoid "commodity pool operator" status, the Fund will
not enter into a futures contract or purchase an option thereon if immediately
thereafter the initial margin deposits for futures contracts held by the Fund
plus premiums paid by it for open options on futures would exceed 5% of the
Fund's total assets. The Fund will not engage in transactions in financial
futures contracts or options thereon for speculation, but only to attempt to
hedge against changes in market conditions affecting the values of securities
which the Fund holds or intends to purchase.

                            INVESTMENT RESTRICTIONS

     The Fund has adopted certain investment restrictions which, together with
the investment objective and policies, cannot be changed without approval by
holders of a majority of its outstanding voting shares. As defined in the
Investment Company Act of 1940, this means the lesser of the vote of (a) 67% or
more of the outstanding shares of the Fund present at a meeting where more than
50% of the outstanding shares are present in person or by proxy or (b) more than
50% of the outstanding shares of the Fund. The Fund may not:

(l)  Purchase securities or make investments other than in accordance with its
investment objective and policies.

(2)  Purchase securities (other than securities of the United States Government,
its agencies or instrumentalities, or the State of Montana or its political
subdivisions, agencies, or instrumentalities) if as a result of such purchase
25% or more of the Fund's total assets would be invested in any industry.

(3)  Make loans, except in accordance with its investment objective and
policies.

(4)  Borrow money except for temporary or emergency purposes and then only in
amounts not exceeding the lesser of 10% of its total assets valued at cost, or
5% of its total assets valued at market, and, in any event, only if immediately
thereafter there is an asset coverage of at least 300%; or mortgage, pledge, or
hypothecate its assets in an amount exceeding 10% of its total assets to secure
temporary or emergency borrowing.

(5)  Make short sales of securities.

(6)  Purchase or retain the securities of any issuer if any of its officers or
directors or of the Investment Adviser owns beneficially more than 1/2 of 1% of
the securities of such issuer and together own more than 5% of the securities of
such issuer.

                                      B-6
<PAGE>

                    INVESTMENT ADVISORY AND OTHER SERVICES

INVESTMENT ADVISER

     ND Money Management, Inc. (the "Investment Adviser"), has been retained
under an Investment Advisory Agreement to act as the Fund's investment adviser,
subject to the authority of the Board of Directors. The Investment Adviser is a
wholly-owned subsidiary of ND Holdings, Inc., a corporation organized under the
laws of the State of North Dakota on September 22, 1987, which is also the
Fund's promoter. The Investment Adviser was incorporated under North Dakota law
on August 19, 1988, and also serves as investment adviser for ND Tax-Free Fund,
Inc., ND Insured Income Fund, Inc., South Dakota Tax-Free Fund, Inc., and
Integrity Fund of Funds, Inc. The address of the Investment Adviser is 1 North
Main, Minot, North Dakota 58703.

     The Investment Adviser furnishes the Fund with investment advice and, in
general, supervises the management and investment program of the Fund. The
Investment Adviser furnishes at its own expense all necessary administrative
services, office space, equipment, and clerical personnel for servicing the
investments of the Fund and investment advisory facilities and executive and
supervisory personnel for managing the investments and effecting the portfolio
transactions of the Fund. In addition, the Investment Adviser pays the salaries
and fees of all officers and directors of the Fund who are affiliated persons of
the Investment Adviser. All other charges and expenses, as more fully described
in the Prospectus under "Expenses," are paid by the Fund.

     Under the Investment Advisory Agreement, the Fund has agreed to pay the
Investment Adviser an annual fee, payable monthly, of 0.60% of the Fund's
average daily net assets. The Fund incurred $51,856, $106,401, and $170,943 in
advisory fees for fiscal years 1994, 1995, and 1996, respectively.

     The Investment Advisory Agreement provides that the Investment Adviser will
not be liable for any error of judgment or mistake of law or for any loss
suffered by the Fund in connection with the matters to which the Investment
Advisory Agreement relates, except a loss resulting from willful misfeasance,
bad faith, or gross negligence on the part of the Investment Adviser in the
performance of its duties or by reason of its reckless disregard of its
obligations and duties under the Investment Advisory Agreement.

     The Investment Advisory Agreement continues in effect from year to year as
long as its continuation is approved at least annually by a majority of the
Directors who are not parties to the Investment Advisory Agreement or interested
persons of any such party except in their capacity as directors of the Fund and
by the shareholders or the Board of Directors. It may be terminated at any time
upon 60 days' written notice by the Fund or by a majority vote of the
outstanding shares and will terminate automatically upon assignment.

     Robert E. Walstad and Peter A. Quist, directors and officers of the Fund,
are also directors and officers of the Investment Adviser as indicated under
"Management of the Fund."

DISTRIBUTION PLAN

     Although shares of the Fund are sold without an initial sales charge, ND
Capital, Inc. (the "Underwriter"), the Fund's principal underwriter, currently
pays dealers who sell Fund shares a commission equal to 3 3/4% (1% of sales of
$1 million or more) of the value of each sale. Such payments are made out of the
Underwriter's own funds. As a further inducement to the sale of Fund shares and
in recognition of the services provided to shareholders, the Underwriter may
also make payments to investment dealers at the annual rate of 0.25% of the
"average net assets" of the Fund which are attributable to shareholders of the
Fund for whom dealers are designated as the dealer of record.  For this purpose,
"average net assets" attributable to a shareholder account means the product of
(i) the average daily share balance of the account times (ii) the Fund's average
daily net asset value per share.  Such payments may be suspended or modified by
the Underwriter at any time and are subject to continuation of the Fund's
Distribution Plan (the "Plan") described below.

     The Fund has adopted the Plan pursuant to Rule 12b-1 under the Investment
Company Act of 1940.  Rule 12b-1 provides that any payments made by the Fund in
connection with the distribution of its shares may be made only pursuant to a
written plan describing all material aspects of the proposed financing of the
distribution and also requires that all agreements with any person relating to
the implementation of a plan must be in writing. The Fund has also entered into
a related Distribution Agreement with the Underwriter.

     The Plan and the related Distribution Agreement provide that the Fund will
pay the Underwriter an annual fee for certain expenses incurred in connection
with the offer and sale of the Fund's shares. The fee is calculated daily and
paid monthly at the annual rate of 0.75% of the average daily net assets of the
Fund. The fee may be used by the Underwriter to cover any expenses primarily
intended to result in the sale of the Fund's shares, including, but not limited
to, sales commissions and other fees paid to dealers who sell Fund shares;
payments made to, and expenses of, persons who provide support services in
connection with the distribution of the Fund's shares; costs relating to the
formulation and implementation of marketing and promotional activities; costs of
printing and distributing prospectuses, statements of additional information,
and reports of the Fund to prospective shareholders; costs involved in
preparing, printing, and distributing advertising and sales literature; and
other sales expenses.

     The Plan continues in effect from year to year, provided that each such
continuance is approved at least annually by a vote of the Board of Directors,
including a majority of the directors who are not "interested persons" of the
Fund and have no direct or indirect financial interest in the operation of the
Plan or in the Distribution Agreement or in any other agreement related to the
Plan (the "Qualified Directors"), cast in person at a meeting called for the
purpose of voting on such continuance. The Plan may be terminated at any time,
without penalty, by vote of a majority of the Qualified Directors or by vote of
the lesser of (a) 67% or more of the shares present at a meeting, if the holders
of more than 50% of the outstanding shares are present or represented by proxy;
or (b) more than 50% of the outstanding shares. Any amendment of the Plan to
increase materially the amount the Fund is authorized to pay thereunder would
require approval by shareholders as described in the preceding sentence. Other
material amendments to the Plan would be required to

                                      B-11
<PAGE>
 
be approved by vote of the Board of Directors of the Fund, including a majority
of the Qualified Directors, cast in person at a meeting called for that purpose.
The Plan further provides that as long as the Plan remains in effect, the
selection and nomination of the Qualified Directors will be committed to the
discretion of the Qualified Directors then in office. It is expected that
payments made under the Plan will serve to encourage the Underwriter and
investment dealers to sell Fund shares and to provide ongoing services to Fund
shareholders.

     The Underwriter has voluntarily agreed (not as part of the Distribution
Agreement) to waive a portion of the fee payable under the Distribution
Agreement during the early stages of the Fund's existence. The Fund incurred
$21,811, $44,334, and $88,756 in fees during fiscal years 1994, 1995, and 1996,
respectively, all of which was used to partially defray costs of commissions
paid to dealers, as described above.

     The Investment Adviser and the Underwriter are subsidiaries of ND Holdings,
Inc. ("Holdings").  Robert E. Walstad and Peter A. Quist, directors and
president and vice president, respectively, of Holdings, are also directors and
officers of the Fund, the Investment Adviser, and the Underwriter. See
"Management of the Fund." Mssrs. Walstad and Quist are also shareholders of
Holdings and, accordingly, will indirectly benefit from the payment of 12b-1
fees by the Fund to the Underwriter.

CUSTODIAN AND TRANSFER AGENT

     First Western Bank & Trust, 900 South Broadway, Minot, North Dakota 58701,
serves as Custodian for the Fund's portfolio securities and cash.  ND Resources,
Inc., ("Resources"), a wholly-owned subsidiary of ND Holdings, Inc., 1 North
Main, Minot, North Dakota 58703, is the Fund's Transfer Agent.  As Transfer
Agent, Resources performs many of the Fund's clerical and administrative
functions, for which it is paid a monthly fee ranging from .16 of 1% of the net
asset value of all outstanding Fund shares up to $10 million down to .09 of 1%
from $50,000,001 and larger.

ACCOUNTANT AND REPORTS TO SHAREHOLDERS

     The Fund's independent public accountant, Brady, Martz & Associates, P.C.,
24 West Central Avenue, Minot, North Dakota 58701, audits and reports on the
Fund's annual financial statements, reviews certain regulatory reports and the
Fund's federal income tax return, and performs other professional accounting,
auditing, tax, and advisory services when engaged to do so by the Fund.
Shareholders will receive annual audited financial statements and semiannual
unaudited financial statements.

                            PORTFOLIO TRANSACTIONS

     Allocation of portfolio brokerage transactions to various brokers is
determined by the Investment Adviser in its best judgment and in a manner deemed
fair and reasonable to shareholders. The primary consideration is prompt and
efficient execution of orders in an effective manner at the most favorable
price. Subject to this consideration, brokers who provide supplemental invest-

                                      B-12
<PAGE>
 
ment research, statistical, or other services to the Investment Adviser may
receive orders for transactions by the Fund. Information thus received will
enable the Investment Adviser to supplement its own research and analysis with
the views and information of other securities firms and may be used for the
benefit of clients of the Investment Adviser other than the Fund. Research
services may include advice as to the value of securities; the advisability of
investing in, purchasing, or selling securities; the availability of securities
or purchasers or sellers of securities; furnishing analyses and reports
concerning issues, industries, securities, economic factors and trends,
portfolio strategy, and performance of accounts; and effecting securities
transactions and performing functions incidental thereto (such as clearance and
settlement). A broker's sales of Fund shares may also be considered a factor if
the Investment Adviser is satisfied that the Fund would receive from that broker
the most favorable price and execution then available for a transaction.
Municipal bonds, notes and short-term securities in which the Fund invests are
traded primarily in the over-the-counter market on a net basis and do not
normally involve either brokerage commissions or transfer taxes. The Fund's cost
of portfolio securities transactions will consist primarily of dealer or
underwriter spreads. The Fund will not engage in principal transactions with
affiliates.

     In effecting purchases and sales of the Fund's portfolio securities, the
Investment Adviser and the Fund may place orders with and pay brokerage
commissions to brokers which are affilliated with the Fund, the Investment
Adviser, the Distributor or selected dealers participating in the offering of
the Fund's shares. Subject to rules adopted by the Securities and Exchange
Commission, the Fund may also purchase municipal securities from other members
of underwriting syndicates of which the Underwriter or other affiliates of the
Fund are members.

     The Board of Directors will monitor the Investment Adviser's performance
with respect to portfolio transactions in order to evaluate the overall
reasonableness of brokerage commissions paid or spreads allowed.

                       PURCHASE AND REDEMPTION OF SHARES

     Fund shares are sold at their public offering price, which is the net asset
value next determined after an order and payment are received in proper form.
The minimum initial investment is $1,000 ($100 for the Monthomatic Investment
Plan), and the minimum subsequent investment is $50, but such minimum amounts
may be changed at any time.

     Upon receipt of a request for redemption, shares will be redeemed by the
Fund at the net asset value next determined following receipt of a properly
executed request with any required documents, less any applicable contingent
deferred sales charge as described in the Prospectus.

     The following example illustrates the operation of the contingent deferred
sales charge. Assume that you own 1,000 shares that you purchased six years ago,
1,000 shares acquired by reinvesting distributions, 1,000 shares that you
purchased two years ago at $10 each, and 1,000 shares that you purchased one
year ago at $10 each. Also assume that the shares now have a net asset value
equal to $20 each. You may redeem the 2,000 shares that you have owned for six
years or acquired by reinvesting distributions without paying a contingent
deferred sales charge. Appreciation on the shares you bought in the last two
years equals $20,000 (the $10 increase in net

                                      B-13
<PAGE>
 
asset value times 2,000 shares), $10,000 of which is attributed to each of the
two years. Because the $20,000 of appreciation is equivalent to 1,000 shares at
the assumed current net asset value of $20 per share, you may redeem 1,000 more
shares without paying a contingent deferred sales charge. If you redeem 3,500
shares, you would have a contingent deferred sales charge on 500 of those
shares. The Fund would treat these 500 redeemed shares as representing a
redemption of the $10,000 investment which you made two years ago. Based on the
assumed net asset value of $20 per share, you would pay a contingent deferred
sales charge equal to $400 (500 shares times $20 per share times the applicable
rate of 4.0%). If in the same year you redeemed your remaining 500 shares, the
Fund would treat this as a redemption of your $10,000 investment made one year
ago, applying a charge at the rate of 4.0%.

     The elimination of the contingent deferred sales charge for redemptions by
certain classes of persons as described in the Prospectus is provided because of
anticipated economies in sales and sales related efforts.

     The Fund may suspend the right of redemption or delay payment more than
seven days (a) during any period when the New York Stock Exchange is closed for
trading (other than customary weekend and holiday closings), (b) when trading in
the markets the Fund normally utilizes is restricted or an emergency exists as
determined by the Securities and Exchange Commission so that disposal of the
Fund's investments or determination of its net asset value is not reasonably
practicable, or (c) for such other periods as the Securities and Exchange
Commission by order may permit for protection of the Fund's shareholders.  The
New York Stock Exchange is currently closed on the following holidays:  New
Year's Day, Presidents' Day, Good Friday, Memorial Day, the Fourth of July,
Labor Day, Thanksgiving, and Christmas.  The amount received by a shareholder
upon redemption may be more or less than the amount paid for such shares
depending on the market value of the Fund's portfolio securities at the time.
When the Fund is requested to redeem shares for which it may not have yet
received good payment (e.g., cash or certified check on a United States bank),
it may delay the mailing of a redemption check until such time as it has assured
itself that good payment has been collected for the purchase of such shares
(which will generally be within 15 calendar days).

                                  UNDERWRITER

     ND Capital, Inc. (the "Underwriter"), a subsidiary of ND Holdings, Inc.,
the Fund's promoter, is the principal underwriter of the Fund's shares in a
continuous public offering.

     Under the terms of the Distribution Agreement between the Fund and the
Underwriter, the Underwriter has agreed to use its best efforts to solicit
orders for the sale of the Fund's shares and to undertake such advertising and
promotion as it believes is reasonable in connection with such solicitation. In
consideration of those services, the Fund pays the Underwriter a fee, calculated
daily and paid monthly, at the annual rate of 0.75% of the average daily net
assets of the shares for the prior month.  As further consideration, the Fund
has agreed to pay the Underwriter the proceeds from any contingent deferred
sales charges imposed on the redemption of shares.  The Fund paid the
Underwriter $27,427 in contingent deferred sales charges for the fiscal year
ended December 31, 1996.

     The Underwriter, in turn, pays a sales commission currently equal to 3 3/4%
(1% on sales of $1 million or more) of the amount invested to dealers who sell
shares (excluding sales to investors 

                                      B-14
<PAGE>
 
exempt from the contingent deferred sales charge). Commission payments totaled
$189,363 in 1993, $284,569 in 1994, $397,967 in 1995, and $404,118 in 1996. As a
further inducement to the sale of Fund shares and in recognition of services
provided to shareholders, the Underwriter may also make commission payments to
dealers at the annual rate of up to 0.25% of the average net assets which are
attributable to shareholders of the Fund for whom such dealers are designated as
the dealers of record.

     The Distribution Agreement must be approved at least annually by the Fund's
Board of Directors and a vote of a majority of the Fund's Directors who are not
"interested persons"' (as defined in the 1940 Act) of the Fund and who have no
direct or indirect financial interest in the operation of the Distribution Plan
or any agreement related thereto or in the Distribution Agreement (the
"Qualified Directors"), by vote cast in person at a meeting called for the
purpose of voting on such approval. The Distribution Agreement will terminate
automatically in the event of its assignment and is terminable with respect to
the Fund without penalty on 60 days' written notice by vote of a majority of the
Qualified Directors or by vote of a majority (as defined in the 1940 Act) of the
outstanding voting securities of the Fund.

                              DIVIDENDS AND TAXES

DIVIDENDS

     All of the net investment income of the Fund is declared daily as a
dividend on shares for which the Fund has received payment. Net investment
income of the Fund consists of all interest income earned on portfolio assets
less all expenses of the Fund. Income dividends will be distributed monthly, and
dividends of net realized capital gains, if any, will normally be paid out once
a year after the end of the Fund's fiscal year. The Fund may at any time vary
the foregoing dividend practices and, therefore, reserves the right from time to
time to either distribute or retain for reinvestment such of its net investment
income and its net short-term and long-term capital gains as the Board of
Directors of the Fund determines appropriate under the then current
circumstances. In particular, and without limiting the foregoing, the Fund may
make additional distributions of net investment income or capital gain net
income in order to satisfy the minimum distribution requirements contained in
the Internal Revenue Code (the "Code"). Dividends will be reinvested in shares
of the Fund unless shareholders indicate in writing that they wish to receive
them in cash.

TAXES

     To the extent that dividends are derived from earnings on Montana state and
local government issues, such dividends will be exempt from Montana income
taxes. However, dividends from the Fund are not exempt to corporations which are
shareholders of the Fund under Montana law.

     For federal income tax purposes, the Fund is generally required to
recognize its unrealized gains and losses at year end on financial futures
contracts and options thereon. Any gain or loss recognized on such financial
instruments is generally considered to be 60% long-term and 40% short-term
without regard to the holding period of the contract or option. One of the
requirements of Subchapter M of the Code is that a fund must derive less than
30% of its gross income from

                                      B-15
<PAGE>
 
gains (not reduced by losses) on stocks and securities and certain other
investments held for less than three months. The Fund may be limited in its
futures transactions in order to prevent recognition of such gains. Dividends
from the Fund will not be eligible for the dividends received deduction
available to corporate shareholders.

     The Fund's futures transactions are subject to special tax provisions that
may accelerate or defer recognition of certain gains or losses, change the
character of certain gains or losses, or alter the holding periods of certain of
the Fund's securities.

     Redemption of shares of the Fund will be a taxable transaction for federal
income tax purposes, and the shareholder will recognize gain or loss in an
amount equal to the difference between the basis of the shares and the amount
received. The gain or loss will be a capital gain or loss and will be long-term
if the shares are held for a period of more than one year. The loss on shares
held six months or less will be a long-term capital loss to the extent any long-
term capital gain distribution is made with respect to such shares during the
period the investor owns the shares. In the case of shareholders holding shares
of the Fund for less than six months 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.

     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 adviser before
investing in the Fund.

     The "Superfund Act of 1986" (the "Superfund Act") imposes a separate tax on
corporations at a rate of 0.12% of the excess of such corporation's "modified
alternative minimum taxable income" over $2,000,000. A portion of tax-exempt
interest, including exempt-interest dividends from the Fund, may be includable
in modified alternative minimum taxable income. Corporate shareholders are
advised to consult with their tax advisers with respect to the consequences of
the Superfund Act.

                        CALCULATION OF PERFORMANCE DATA

     The Fund may publish certain performance figures in advertisements from
time to time. These performance figures may include yield, tax equivalent yield,
and total return figures.

YIELD

     Yield reflects the income per share deemed earned by the Fund's portfolio
investments. Yield is determined by dividing the net investment income per share
deemed earned during the preceding 30-day period by the maximum offering price
per share on the last day of the period and annualizing the result according to
the following formula:

                      YIELD = 2[(a-b + 1)/6/ - 1]
                                 ---             
                                 cd

                                      B-16
<PAGE>
 
     Where:

     a =     dividends and interest earned during the period.

     b =     expenses accrued for the period (net of reimbursements).

     c =     the average daily number of shares outstanding during the period
             that were entitled to receive dividends.

     d =     the maximum offering price per share on the last day of the period.

     To calculate interest earned (for the purpose of "a" above), the Fund will:

     (a) Compute the yield to maturity of each obligation held by the Fund based
     on the market value of the obligation at the close of business on the last
     business day of each month, or, with respect to obligations purchased
     during the month, the purchase price.

     (b) Divide the yield to maturity by 360 and multiply the quotient by the
     market value of the obligation (including actual accrued interest) to
     determine the interest income on the obligation for each day of the
     subsequent month that the obligation is in the portfolio.

     The maturity of an obligation with a call provision is the next call date
on which the obligation reasonably may be expected to be called or, if none, the
maturity date.

     In the case of an obligation issued without original issue discount and
having a current market discount, the coupon rate of interest is used in lieu of
the yield to maturity. In the case of an obligation with original issue
discount, if the discount based on the current market value exceeds the then-
remaining portion of original issue discount (market discount), the yield to
maturity is the imputed rate based on the original issue discount calculation.
In the case of an obligation with original issue discount, if the discount based
on the current market value is less than the then-remaining portion of original
issue discount (market premium), the yield to maturity is based upon market
value.

TAX EQUIVALENT YIELD

     Tax equivalent yield shows the yield from a taxable investment which would
produce an after-tax yield equal to that of a fund that invests in tax-exempt
securities. It is computed by dividing the tax-exempt portion of the Fund's
yield (as calculated above) by one minus a stated income tax rate and adding the
product to the portion (if any) of the Fund's yield that is not tax-exempt.

TOTAL RETURN

     Total return is the percentage change in the value of a hypothetical
investment that has occurred in the indicated time period, taking into account
the imposition of various fees, except the contingent deferred sales charge, and
assuming the reinvestment of all dividends and distributions. Cumulative total
return reflects the Fund's performance over a stated period of time and is
computed as follows:

                             ERV - P = Total Return
                             -------               
                                P

                                      B-17
<PAGE>
 
     Where:

          ERV = ending redeemable value of a hypothetical $1,000 payment made at
          the beginning of the base period, assuming reinvestment of all
          dividends and distributions
     P = a hypothetical initial payment of $1,000

     Average annual total return reflects the hypothetical annually compounded
return that would have produced the same cumulative total return if the Fund's
performance had been constant over the entire period and is computed according
to the following formula:

                               P(1 + T)/n/ = ERV

     Where:

      P = a hypothetical initial payment of $1,000

      T = average annual total return

      n = number of years

          ERV = ending redeemable value of a hypothetical $1,000 payment made at
          the beginning of the base period, assuming reinvestment of all
          dividends and distributions

     All performance figures are based on historical results and are not
intended to indicate future performance.


                        TAX-FREE VERSUS TAXABLE INCOME

     The following table shows the rate of return an individual Montana investor
would need to receive from a taxable investment to equal the rate of return from
the Fund. The table assumes that the investor's income from a taxable investment
would be subject to federal income tax at the maximum federal rate and Montana
state income tax at a rate equal to 11% of the Montana taxable income. This
assumes that the maximum Montana individual income tax rate will remain at 11%.

    
     Our calculations are based on the maximum federal statutory tax rates
applicable in 1997. The highest marginal federal tax rate for 1997 can be in
excess of the statutory maximum federal tax rate due to the disallowance of a
portion of itemized deductions and personal exemptions. We have calculated the
combined marginal tax rate based on families with adjusted gross incomes of
$180,000 to $300,000 for 1997 filing on a married filing jointly basis with two
dependent children. At this level of income, the highest federal marginal tax
rate is 44.02%. In addition, this assumes the investor is not subject to
alternative minimum tax and has a reasonable amount of itemized deductions.

     The following table uses the combined marginal tax rate of 50.18% for
adjusted gross income of $180,000 to $300,000 to present the equivalent taxable
yield for taxpayers in the situations presented above assuming that the federal
tax rates remain the same and a Montana tax rate for 1997 of 11%.

                       APPENDIX--RATINGS OF INVESTMENTS

     The four highest ratings of Moody's Investors Service, Inc. ("Moody's"),
for municipal bonds are Aaa, Aa, A, and Baa. Municipal bonds rated Aaa are
judged to be of the "best quality." The rating of Aa is assigned to municipal
bonds which are of "high quality by all standards," but as to which margins of
protection or other elements make long-term risks appear somewhat larger than
Aaa rated municipal bonds. The Aaa, Aa, and A rated municipal bonds comprise
what are generally known as "high grade bonds."  Municipal bonds which are rated
A by Moody's possess many favorable investment attributes and are considered
"upper medium grade obligations."   Factors giving security to principal and
interest of A rated municipal bonds are considered adequate, but elements may be
present which suggest a susceptibility to impairment sometime in the future.
Municipal bonds which are rated Baa are considered as medium grade obligations;
i.e., they are neither highly protected nor poorly secured. Interest coverage
and principal security appear adequate for the present, but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and, in
fact, have speculative characteristics as well.

     The four highest ratings of Standard & Poor's Corporation ("S&P") for
municipal bonds are AAA, AA, A, and BBB. Municipal bonds rated AAA have the
highest rating assigned by S&P to a debt obligation. Capacity to pay interest
and repay principal is extremely strong. Bonds rated AA have a very strong
capacity to pay interest and repay principal and differ from the highest rated
issues only in small degree. Bonds rated A have a strong capacity to pay
interest and repay principal although they are somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than bonds
in higher rated categories. Bonds rated BBB are regarded as having an adequate
capacity to pay interest and repay principal. Whereas they normally exhibit
adequate protection parameters, adverse economic conditions or changing
circumstances are more likely to lead to a weakened capacity than for bonds in
higher rated categories.

     The "debt securities" included in the discussion of temporary investments
are corporate (as opposed to municipal) debt obligations rated AAA, AA, or A by
S&P or Aaa, Aa, or A by Moody's. Corporate debt obligations rated AAA by S&P are
"highest grade obligations." Obligations bearing the rating of AA also qualify
as "high grade obligations" and "in the majority of instances differ from AAA
issues only in small degree." Corporate debt obligations rated A by S&P are
regarded as "upper medium grade" and have "considerable investment strength, but
are not entirely free from adverse effects of changes in economic and trade
conditions." The Moody's corporate debt ratings of Aaa, Aa, and A do not differ
materially from those set forth above for municipal bonds.

     Taxable or tax-exempt commercial paper ratings of A-l or A-2 by S&P and P-l
or P-2 by Moody's are the highest paper ratings of the respective agencies. The
issuer's earnings, quality of long-term debt, management, and industry position
are among the factors considered in assigning such ratings.

     Subsequent to its purchase by the Fund, an issue of Municipal Securities or
a temporary investment may cease to be rated or its rating may be reduced below
the minimum required for purchase by the Fund. Neither event requires the
elimination of such obligation from the Fund's portfolio, but the Investment
Adviser will consider such an event in its determination of whether the Fund
should continue to hold such obligation in its portfolio. To the extent that the

                         INDEPENDENT AUDITOR'S REPORT

To the Shareholders and Board of Directors of
Montana Tax Free Fund, Inc.

We have audited the accompanying statement of assets and liabilities of Montana
Tax Free Fund, Inc. (the Fund), including the schedule of investments, as of
December 31, 1996, the related statement of operations for the year then ended,
the statements of changes in net assets for each of the two years in the period
then ended, and the financial highlights for each of the three periods then
ended and for the period from inception (August 12, 1993) through December 31,
1993.  These financial statements and financial highlights are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements.    Our procedures included confirmation of securities owned as of
December 31, 1996, by correspondence with the custodian.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Montana Tax Free Fund, Inc. as of December 31, 1996, the results of its
operations for the year then ended, the changes in its net assets, and financial
highlights for each of the respective periods stated in the first paragraph, in
conformity with generally accepted accounting principles.

MONTANA TAX-FREE FUND, INC.
NOTES TO FINANCIAL STATEMENTS  December 31, 1996

NOTE 1.   ORGANIZATION

          Montana Tax-Free Fund, Inc. (the Fund) is registered under the
          Investment Company Act of 1940 as a non-diversified, open-end
          management investment company. The Fund incorporated under the laws of
          the State of North Dakota on April 15, 1993 and commenced operations
          on August 12, 1993. The Fund's objective is to provide as high a level
          of current income exempt from federal and Montana income taxes as is
          consistent with preservation of capital. The Fund will seek to achieve
          this by investing primarily in a portfolio of Montana tax-exempt
          securities.

          Shares of the Fund are offered with no initial sales charge. Shares
          may be subject to a contingent deferred sales charge, if those shares
          are redeemed within five years of purchase.

NOTE 2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

          INVESTMENT SECURITY VALUATION - Investments in securities traded on
          national securities exchanges are valued at the last reported sales
          price at the close of each business day. Securities for which market
          quotations are not readily available are valued at fair value as
          determined in good faith by the portfolio management team. The Fund
          follows industry practice and records security transactions on the
          trade date.

          The Fund concentrates its investments in a single state. This
          concentration may result in the Fund investing a relatively high
          percentage of its assets in a limited number of issuers.

          FEDERAL AND STATE INCOME TAXES - The Fund's policy is to comply with
          the requirements of the Internal Revenue Code that are applicable to
          regulated investment companies, and to distribute all of its net
          investment income and any net realized gain on investments, to its
          shareholders. Therefore, no provision for income taxes is required.

          DISTRIBUTIONS TO SHAREHOLDERS -Dividends from net investment income,
          declared daily and payable monthly, are reinvested in additional
          shares of the Fund at net asset value or payable in cash. Capital
          gains, when available, are distributed along with the last income
          dividend of the calendar year.

          INVESTMENT INCOME - Dividend income is recognized on the ex-dividend
          date and interest income is recognized daily on an accrual basis.
          Premiums and discounts on securities purchased are amortized using the
          effective interest method over the life of the respective securities,
          unless callable, in which case they are amortized to the earliest call
          date.

          FUTURES CONTRACTS - The Fund may purchase and sell financial futures
          contracts to hedge against changes in the values of tax-exempt
          municipal securities the Fund owns or expects to purchase.

          A futures contract is an agreement between two parties to buy or sell
          units of a particular index or a certain amount of U.S. Government or
          municipal securities at a set price on a future date. Upon entering
          into a futures contract, the Fund is required to deposit with a broker
          an amount of cash or securities equal to the minimum "initial margin"
          requirement of the futures exchange on which the contract is traded.
          Subsequent payments ("variation margin") are made or received by the
          Fund, dependent on the fluctuations in the value of the underlying
          index, and are recorded for financial reporting purposes as unrealized
          gains or losses by the Fund. When entering into a closing transaction,
          the Fund will realize, for book purposes, a gain or loss equal to the
          difference between the value of the futures contracts sold and the
          futures contracts to buy. Unrealized appreciation (depreciation)
          related to open futures contracts is required to be treated as
          realized gain (loss) for Federal income tax purposes.

          Certain risks may arise upon entering into futures contracts. These
          risks may include changes in the value of the futures contracts that
          may not directly correlate with changes in the value of the underlying
          securities.

                                      F-7
<PAGE>
 
          USE OF ESTIMATES - The preparation of financial statements in
          conformity with generally accepted accounting principles requires
          management to make estimates and assumptions that affect the reported
          amounts of assets and liabilities and disclosure of contingent assets
          and liabilities at the date of the financial statements and the
          reported amounts of revenues and expenses during the reporting period.
          Actual results could differ from those estimates.

NOTE 3.   CAPITAL SHARE TRANSACTIONS

          As of December 31, 1996, there were 200,000,000 shares of $.001 par
          authorized; 3,456,719 and 2,395,706 were outstanding at December 31,

Item 27.  INDEMNIFICATION

          Section 4 of the Distribution Agreement [Exhibit (6)(a)] provides for
the indemnification of ND Capital, Inc., Registrant's principal underwriter,
against losses. Section 12 of the Transfer Agency Agreement [Exhibit 9] provides
for the indemnification of ND Resources, Inc., Registrant's transfer agent,
against certain losses.

          Indemnification of directors, officers, employees, and agents of
Registrant is required under Section 10-19.1-91 of the North Dakota Century
Code. In addition, Registrant has obtained an insurance policy on behalf of
directors and officers against any liability asserted against and incurred by
the person in or arising from that person's official capacity to the extent
permitted by law.

          In no event will Registrant indemnify its directors, officers,
employees, or agents against any liability to which such person would otherwise
be subject by reason of his willful misfeasance, bad faith, gross negligence in
the performance of his duties, or by reason of his reckless disregard of the
duties involved in the conduct of his office arising under his agreement with
Registrant.

          Insofar as indemnification for liability arising under the Securities
Act of 1933 may be permitted to directors, officers, and controlling persons of
Registrant pursuant to the foregoing provisions, or other-wise, Registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by Registrant of expenses incurred or
paid by a director, officer, or controlling person of Registrant in the
successful defense of any action, suit, or proceeding) is asserted by such
director, officer, or controlling person in connection with the securities being
registered, 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 question of whether such indemnification by it is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

          Anything in the North Dakota Business Corporation Act (Chapter 10-19
through 10-23 of the North Dakota Century Code), the Fund's Articles of
Incorporation or Bylaws, or the Investment Advisory, Distribution, or Transfer
Agency Agreements to the contrary notwithstanding, Registrant will comply in all
respects with the provisions of Investment Company Act Release No. 11330
(September 4, 1980) concerning indemnification.
