May 15, 1996

Dear Shareholders:

NATIONAL TAX-EXEMPT FUND ACHIEVED A 3.48%* TOTAL RETURN FOR THE SIX-MONTH PERIOD
ENDED MARCH 31, 1996. This return includes reinvested distributions but not the
fund's sales charge. The fund's return compares to the Lipper General Municipal
Bond Funds Average return of 2.71% and the Lehman Brothers Municipal Bond Index
return of 2.87% for the same six-month period. The fund's outperformance is
largely due to its relatively long effective duration and long call protection
(which is the length of time during which a security cannot be redeemed by the
issuer) during the declining interest rate environment in late 1995.

THROUGHOUT MOST OF THIS PERIOD, TAX-FREE BONDS OUTPERFORMED THEIR TAXABLE
COUNTERPARTS, AS FLAT TAX PROPOSALS CONTINUED TO LOSE SUPPORT. Today, investors
only need to be in the 15% tax bracket before tax-exempt issues become a
preferable option. During the last few months of 1995, interest rates fell as
investors projected economic weakness. In early 1996, however, the economy began
to strengthen and interest rates began to rise, resulting in a decline in bond
prices. While the fund's longer effective duration benefited the fund in late
1995, this long duration had a negative impact on the fund's performance as
rates rose. (See page 6 for more information about effective duration.) However,
there was a positive side effect of rising interest rates: the viability of many
scheduled municipal bond refundings was diminished, reducing the market's
estimate of new issue supply. The reduced new issue estimate - combined with the
existing supply shortage - caused municipal bond prices to fall less than
taxable bonds. 

AS OF MARCH 31, THE FUND'S POSITION IN INVERSE FLOATING RATE MUNICIPAL
SECURITIES REPRESENTED ABOUT 4% OF TOTAL ASSETS. Inverse floating rate
securities have an inverse relationship with interest rates. Therefore, as
interest rates fell in 1995, the value of these securities and their coupons
increased. Conversely, as rates rose in early 1996, these securities dropped in
value and their coupons fell somewhat. We believe these securities will remain
attractive holdings over a longer investment horizon and will continue to
provide relatively high tax-exempt cash flow compared to the fund's more
traditional municipal bonds. While we plan to continue to invest in these
securities, it's important to recognize that in volatile interest rate
environments they may cause the fund to experience increased price and income
volatility.


* PAST PERFORMANCE DOES NOT GUARANTEE FUTURE RESULTS. THE INVESTMENT RETURN AND
PRINCIPAL VALUE OF AN INVESTMENT WILL FLUCTUATE SO THAT FUND SHARES, WHEN SOLD,
MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST.

WE RECENTLY BEGAN INCREASING THE FUND'S INCOME EARNING POWER BY SELECTIVELY
ADDING TO THE FUND'S NON-RATED AND INVERSE FLOATING RATE SECURITIES. Even as
interest rates fluctuate, the relatively high, fixed coupons of non-rated
securities tend to make their prices less volatile. The income generated by
inverse floating rate securities is still currently higher than that of more
traditional municipal bonds; however, because of their inverse relationship with
interest rates, a substantial rise in rates could reduce the income of inverse
floaters to below that of traditional bonds, as well as cause their values to
decline. 

THE FUND'S GEOGRAPHIC FOCUS CONTINUES TO BE ON THE CENTRAL, SOUTHWESTERN AND 
NORTHWESTERN UNITED STATES. As of March 31, Indiana, Texas, Illinois, 
Wisconsin and North Dakota were the fund's largest state concentrations. 
Although Texas still has a fairly large weighting, we have reduced the fund's 
position in Texas since we last reported to you because we were able to sell 
many of these holdings at attractive prices. In addition, we purchased a 
California general obligation bond during this period as this state's economy 
appears to be showing signs of recovery. We continue to view parts of the 
West and Southeast favorably and will watch for additional opportunities to 
invest in these areas.

WE EXPECT THE SUPPLY OF OUTSTANDING MUNICIPAL BONDS TO CONTINUE TO SHRINK AS 
IT HAS FOR THE PAST TWO YEARS, WHICH SHOULD CAUSE TAX-FREE BONDS TO CONTINUE 
TO OUTPERFORM THEIR TAXABLE COUNTERPARTS.  However, we also expect to see 
further volatility in the municipal market due to the ongoing tax-reform 
debate and fluctuating expectations regarding new issue supply. We will 
continue to look for opportunities to increase the fund's call protection and 
yield while actively monitoring credit quality.

Thank you for investing in National Tax-Exempt Fund. We are dedicated to serving
your financial needs and look forward to helping you reach your financial goals
in 1996.

Sincerely,

/s/ Ronald Reuss

May 15, 1996

Dear Shareholders:

MINNESOTA TAX-EXEMPT FUND ACHIEVED A 2.78%* TOTAL RETURN FOR THE SIX-MONTH 
PERIOD ENDED MARCH 31, 1996. This return includes reinvested distributions 
but not the fund's sales charge. The fund's return compares to the Lipper 
Minnesota Municipal Bond Funds Average return of 2.23% and the Lehman 
Brothers Municipal Bond Index return of 2.87% for the same six-month period. 
The fund outperformed the Lipper average because of its emphasis on 
income-producing securities, its relatively long effective duration and its 
long call protection during the declining interest rate environment in late 
1995.

DURING MOST OF THIS PERIOD, TAX-FREE BONDS OUTPERFORMED THEIR TAXABLE 
COUNTERPARTS, AS FLAT TAX PROPOSALS CONTINUED TO LOSE SUPPORT. Today, 
investors only need to be in the 15% tax bracket before tax-exempt issues 
become a preferable option. During the last few months of 1995, interest 
rates fell as investors projected economic weakness. In early 1996, however, 
the economy began to strengthen and interest rates began to rise, resulting 
in a decline in bond prices. While the fund's longer effective duration 
benefited the fund in late 1995, this long duration had a negative impact on 
the fund's performance as rates rose. (See page 6 for more information about 
effective duration.) However, there was a positive side effect of rising 
interest rates: the viability of many scheduled municipal bond refundings was 
diminished, reducing the market's estimate of new issue supply. The reduced 
new issue estimate - combined with the existing supply shortage - caused 
municipal bond prices to fall less than taxable bonds. 

WE MAINTAINED THE FUND'S POSITION IN INVERSE FLOATING RATE MUNICIPAL 
SECURITIES, WHICH REPRESENTED ABOUT 8% OF TOTAL ASSETS ON MARCH 31. Inverse 
floating rate securities have an inverse relationship with interest rates. 
Therefore, as interest rates fell in 1995, the value of these securities and 
their coupons increased. Conversely, as rates rose in early 1996, these 
securities dropped in value and their coupons fell somewhat. We believe these 
securities will remain attractive holdings over a longer investment horizon 
and will continue to provide relatively high tax-exempt cash flow compared to 
the fund's more traditional municipal bonds. While we plan to maintain our 
position in these securities, it's important to recognize that in volatile 
interest rate environments they may cause the fund to experience increased 
price and income volatility.

YEAR, 6.74% FIVE YEAR AND 6.85% SINCE INCEPTION. ALL RETURNS INCLUDE 
REINVESTED DISTRIBUTIONS AND THE FUND'S 4% SALES CHARGE. PAST PERFORMANCE 
DOES NOT GUARANTEE FUTURE RESULTS.


DURING THIS SIX-MONTH PERIOD, WE TRADED SECURITIES WITH SHORTER CALL 
PROTECTION FOR THOSE WITH LONGER CALL PROTECTION. Call protection is the 
length of time during which a security cannot be redeemed by the issuer. We 
believe this longer call protection will not only protect the fund's tax-free 
income for a longer period of time, but will enhance the price performance 
potential of the fund. However, keep in mind that securities with longer call 
protection may lengthen the effective duration of the fund which increases 
its volatility. Going forward, we will continue to trade shorter call 
securities for longer call securities.

WE HAVE DIVERSIFIED THE FUND BY OWNING BOTH GENERAL OBLIGATION AND REVENUE 
BONDS THROUGHOUT THE STATE. Minnesota's general obligation bonds were 
recently upgraded by Moody's Investor Service, a rating agency, from Aa1 to 
an Aaa rating. This is the highest rating and has been granted to only nine 
other states. Moody's cited the state's low unemployment rate, diverse 
economy and maintenance of a sound financial position as reasons for the 
rating upgrade. In addition, school district bonds guaranteed by the state of 
Minnesota were upgraded from Aa to Aa1. Within the revenue bond category, the 
fund has maintained its overweighted position in the hospital sector, as 
Minnesota continues to show leadership in health care reform and legislation.

WE EXPECT THE SUPPLY OF OUTSTANDING MUNICIPAL BONDS TO CONTINUE TO SHRINK AS 
IT HAS FOR THE PAST TWO YEARS, WHICH SHOULD CAUSE TAX-FREE BONDS TO CONTINUE 
TO OUTPERFORM THEIR TAXABLE COUNTERPARTS. However, we also expect to see 
further volatility in the municipal market due to the ongoing tax-reform 
debate and fluctuating expectations regarding new issue supply. We will 
continue to look for opportunities to increase the fund's call protection and 
yield while actively monitoring credit quality.

Thank you for investing in Minnesota Tax-Exempt Fund. We are committed to 
providing you with quality management services and look forward to helping 
you reach your financial goals in 1996.

                               EFFECTIVE DURATION

Effective duration estimates the interest rate risk of a security, in other
words how much the value of the security is expected to change with a given
change in interest rates. The longer a security's effective duration, the more
sensitive its price is to changes in interest rates. For example, if interest
rates increased by 1%, the market value of a bond with an effective duration of
five years would decrease by about 5%, with all other factors being constant.

It is important to understand that, while a valuable measure, effective duration
is based on certain assumptions and has several limitations. It is most
effective as a measure of interest rate risk when interest rate changes are
small, rapid and occur equally across short-, intermediate- and long-term
interest rates. In addition, effective duration is difficult to calculate
precisely, especially in the case of a bond that is callable prior to maturity.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
                 INVESTMENTS IN SECURITIES
                 The value of certain fixed-income securities
                 will be provided by an independent pricing
                 service, which determines these valuations at
                 a time earlier than the close of the Exchange.
                 Fixed-income securities for which prices are
                 not available from an independent pricing
                 service but where an active market exists will
                 be valued using market quotations obtained
                 from one or more dealers that make markets in
                 the securities.
 
                 Occasionally events affecting the value of
                 such securities may occur between the time
                 valuations are determined and the close of the
                 Exchange. If events materially affecting the
                 value of such securities occur, if the
                 Company's management determines for any other
                 reason that valuations provided by the pricing
                 service are inaccurate or when market
                 quotations are not readily available,
                 securities will be valued at their fair value
                 according to procedures decided upon in good
                 faith by the Board of Directors. Short-term
                 securities with maturities of 60 days or less
                 are valued at amortized cost, which
                 approximates market value.
 
                 Financial futures are valued at the last
                 settlement price established each day by the
                 board of trade or exchange on which they are
                 traded. Such valuations are determined using
                 independent pricing services or prices quoted
                 by independent brokers.
 
                 Securities transactions are accounted for on
                 the date the securities are purchased or sold.
                 Realized gains and losses are calculated on
                 the identified-cost basis. Interest income,
                 including amortization of bond discount and
                 premium computed on a level-yield basis, is
                 accrued daily.
 
                 Minnesota Tax-Exempt Fund concentrates its
                 investments in Minnesota and, therefore, may
                 have more credit risk related to the economic
                 conditions of Minnesota than a portfolio with
                 a broader geographical diversification.
 
                 FUTURES TRANSACTIONS
                 In order to gain exposure to or protect from
                 changes in the market, the funds may buy and
                 sell financial futures contracts and related
                 options. Risks of entering into

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
                 futures contracts and related options include
                 the possibility that there may be an illiquid
                 market and that a change in the value of the
                 contract or option may not correlate with
                 changes in the value of the underlying
                 securities.
 
                 Upon entering into a futures contract, the
                 funds are required to deposit either cash or
                 securities in an amount (initial margin) equal
                 to a certain percentage of the contract value.
                 Subsequent payments (variation margin) are
                 made or received by the funds each day. The
                 variation margin payments are equal to the
                 daily changes in the contract value and are
                 recorded as unrealized gains and losses. The
                 funds recognize a realized gain or loss when
                 the contract is closed or expires.
 
                 SECURITIES PURCHASED ON A WHEN-ISSUED BASIS
                 Delivery and payment for securities that have
                 been purchased by the funds on a
                 forward-commitment or when-issued basis can
                 take place a month or more after the
                 transaction date. During this period, such
                 securities do not earn interest, are subject
                 to market fluctuation and may increase or
                 decrease in value prior to their delivery.
                 Each fund maintains, in segregated accounts
                 with the custodian, assets with a market value
                 equal to the amount of its purchase
                 commitments. The purchase of securities on a
                 when-issued or forward-commitment basis may
                 increase the volatility of each fund's net
                 asset value if the funds make such purchases
                 while remaining substantially fully invested.
 
                 As of March 31, 1996, the funds had no
                 outstanding when-issued or forward-
                 commitments.
 
                 FEDERAL TAXES
                 Each fund is treated separately for federal
                 income tax purposes. Each fund intends to
                 comply with the requirements of the Internal
                 Revenue Code applicable to regulated
                 investment companies and not be subject to
                 federal income tax. Therefore, no income tax
                 provision is required. In addition, on a
                 calendar-year basis, the funds will distribute
                 substantially all of their taxable net
                 investment income and realized gains, if any,
                 to avoid the payment of any federal excise
                 taxes.
 
                 Net investment income and net realized gains
                 (losses) may differ for financial statement
                 and tax purposes primarily because of losses
                 deferred due to 'wash sale' transactions and
                 market discount amortization.
 
                 The character of distributions made during the
                 year from net investment income or net
                 realized gains may differ from its ultimate
                 characterization for federal income tax
                 purposes. In addition, due to the timing of
                 dividend distributions, the fiscal year in
                 which amounts are distributed may differ from
                 the year that the income or realized gains
                 (losses) were recorded by the funds.
 
                 DISTRIBUTIONS TO SHAREHOLDERS
                 Distributions to shareholders from net
                 investment income are declared daily and paid
                 monthly. Net realized gains distributions, if
                 any, will be made at least annually.
                 Distributions are payable in cash or
                 reinvested in additional shares.
 
                 REPURCHASE AGREEMENTS
                 For repurchase agreements entered into with
                 certain broker-dealers, the funds, along with
                 other affiliated registered investment
                 companies, may transfer uninvested cash
                 balances to a joint trading account, the daily
                 aggregate of which is invested in repurchase
                 agreements secured by U.S. government or
                 agency obligations. Securities pledged as
                 collateral for all individual and joint
                 repurchase agreements are held by the funds'
                 custodian bank until maturity of the
                 repurchase agreement. Provisions for

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
                 all agreements ensure that the daily market
                 value of the collateral is in excess of the
                 repurchase amount, including accrued interest,
                 to protect the funds in the event of a
                 default.
 
                 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
                 disclosures of contingent assets and
                 liabilities at the date of the financial
                 statements and the reported results of
                 operations during the reporting period. Actual
                 results could differ from those estimates.

(5) EXPENSES
                 The company has entered into an investment
                 management agreement with Piper Capital
                 Management Incorporated (Piper Capital) under
                 which Piper Capital manages each fund's assets
                 and furnishes related office facilities,
                 equipment, research and personnel. The
                 agreement requires each fund to pay Piper
                 Capital a monthly fee based on average daily
                 net assets. The fee for each fund is equal to
                 an annual rate of 0.50% of the first $250
                 million in net assets, 0.45% of the next $250
                 million and 0.40% of net assets in excess of
                 $500 million.
 
                 Each fund also pays Piper Jaffray Inc. (Piper
                 Jaffray), the funds' distributor, a monthly
                 fee for providing shareholder services and
                 distribution-related services. The fee is
                 limited to an annual rate of 0.30% of average
                 daily net assets for each fund and includes
                 0.25% payable as a servicing fee and 0.05%
                 payable as a distribution fee. For the year
                 ending September 30, 1996, Piper Jaffray
                 voluntarily agreed to limit the fee to an
                 annual rate of 0.22% of each fund's average
                 daily net assets.

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
                 The company has also entered into shareholder
                 servicing agreements under which Piper Jaffray
                 and Piper Trust Company perform various
                 transfer and dividend disbursing agent
                 services for accounts held at the respective
                 company. The fees, which are paid monthly to
                 Piper Jaffray and Piper Trust Company for
                 providing these services, are equal to an
                 annual rate of $7.50 per active shareholder
                 account and $1.60 per closed account.
 
                 In addition to the investment management,
                 distribution and shareholder account servicing
                 fees, each fund is responsible for paying most
                 other operating expenses including: outside
                 directors' fees and expenses; custodian fees;
                 registration fees; printing and shareholder
                 reports; transfer agent fees and expenses;
                 legal, auditing and accounting services;
                 insurance; interest; taxes and other
                 miscellaneous expenses.
 
                 Expenses paid indirectly represent a reduction
                 of custodian fees for earnings on cash
                 balances maintained by the funds.
 
                 Sales charges received by Piper Jaffray for
                 distributing the funds' shares were $12,284
                 and $83,245 for National Tax-Exempt Fund and
                 Minnesota Tax-Exempt Fund, respectively, for
                 the six months ended March 31, 1996.
 
(6) CAPITAL LOSS CARRYOVERS
                 For federal income tax purposes, the following
                 funds had capital loss carryovers at September
                 30, 1995, which, if not offset by subsequent
                 capital gains, will expire as noted. It is
                 unlikely the board of directors will authorize
                 a distribution of any net realized capital
                 gains until the available capital loss
                 carryovers have been offset or expired.
