PRESIDENT'S LETTER
- --------------------------------------------------------------------------------
May 15, 1997


DEAR SHAREHOLDERS:

What are you expecting from the markets this year? There's no denying that the
stock market's been on a bit of a roller coaster ride of late. The past six
months alone have seen record Dow highs, followed by quick downturns and
rebounds that are higher still. In fact, stock and bond prices have seen
unprecedented growth for almost 15 years. And, fortunately, more of you than
ever are sharing in these gains.

     Word has it that investors' EXPECTATIONS have soared right along with these
phenomenal returns, and that's troubling. Don't get me wrong - we're happy about
the gains investors have enjoyed. But it's important that we all understand the
markets' potential for volatility and balance that with a good dose of reality.

     Here's what I mean. According to Ibbotson Associates, the markets have, on
average, returned 11% in large-company stocks and 5% in long-term government
bonds per year since 1926.* Yet today's investors expect much more. I recently
read the results of a national survey by Louis Harris and Associates that found
a wide majority of investors expect at least a 14% stock market return over the
next 10 years (which is the average annual return from the last decade). Some
predict even greater returns.

     No matter what the markets bring this year, I believe it's important to
maintain a long-term perspective. History shows that it's common for investors
to bail out at the first signs of a market downturn. But if I've learned one
thing from my 30 years in the financial services industry, it's this: you can
gain only if you stay in the game for the long term. Remember that market and
interest rate volatility (like we saw in March) are normal parts of investing.
I've never met anyone who can always time the market to their advantage. Here's
an adage to keep in mind: focus on "TIME IN the market," not "TIMING the
market."

     My other advice for weathering the bumpy markets? Stay in touch with your
Investment Executive. Together, you have probably already set your financial
goals and formulated a plan to help you reach them. Stick to that plan. During
this uncertain time, your Investment Executive can help you sort through the
clutter and tune out the market noise. Best of all, your broker can lend you the
perspective gained from years of experience and help you focus on long-term
results.

Thank you for your investment and best wishes for the balance of 1997.

Sincerely,

/s/ William H. Ellis

GROWTH AND INCOME FUND
- --------------------------------------------------------------------------------
May 15, 1997

DEAR SHAREHOLDERS:

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 1997, GROWTH AND INCOME FUND CLASS A 
PROVIDED AN 8.68%* TOTAL RETURN WITH ALL DIVIDENDS AND CAPITAL GAINS 
REINVESTED, BUT NOT INCLUDING THE SALES CHARGE. The fund performed in line 
with the Lipper Growth and Income Funds Average, which advanced 8.65%, and 
trailed the Standard & Poor's 500 Index,** which gained 11.23% during the 
same time frame. The fund received strong investment results from energy, 
financial, health care and retail stocks. However, these gains were partially 
offset by weakness in capital goods and services, utilities and consumer 
durables, sectors*** in which the fund was overweighted.*** This, along with 
the S&P 500's heavy emphasis on large-cap, blue chip stocks,***  helped the 
index outperform the fund. The largest stocks in the S&P 500 (based on market 
capitalization) propelled the index to its strong performance. In our 
opinion, many of these large stocks are highly overvalued.***

THROUGHOUT MUCH OF THE PERIOD, ECONOMIC CONDITIONS WERE FAVORABLE AND THE STOCK
MARKET FARED RELATIVELY WELL. Large-cap growth stocks recorded solid investment
results in this modestly growing economic environment. From early February
through the end of March, signs of a strengthening economy, such as an increase
in consumer spending, caused interest rates to rise due to fears of higher
inflation. By mid-March, these fears carried over to the stock market, sending
prices down

GROWTH AND INCOME FUND  (CONTINUED)
- --------------------------------------------------------------------------------
sharply during the last three weeks of the month. Large-cap growth stocks and
technology stocks were most affected by the decline. In its effort to combat
higher inflation, the Federal Reserve on March 25 raised the federal funds rate
for the first time in two years. Despite the market downturn in March, large-cap
stocks in general performed very well during the period.

CYCLICAL STOCKS,*** WHICH ARE WIDELY REPRESENTED IN THE FUND, DID NOT BENEFIT
FROM THE INCREASE IN ECONOMIC ACTIVITY. Generally cyclicals, which include the
capital goods, consumer durables and basic materials sectors, outperform the
market in a robust economic environment. Their prices tend to rise due to higher
earnings resulting from economic strength. While earnings for cyclical stocks
were higher during the period, their prices remained relatively flat.
Additionally, cyclicals, along with virtually every other type of stock, were
not spared from the market's sharp downturn in March. Despite our general
disappointment with the performance of these stocks, we still realized
relatively good investment results from two in particular: Air Products &
Chemicals (approximately 2% of the fund's total assets on March 31, 1997) and
duPont (E.I.) de Nemours (1%). Both companies recorded strong earnings due to a
strong economic climate and improving profit margins.

ENERGY STOCKS CONTINUED TO BE WELL REPRESENTED IN THE PORTFOLIO, BECAUSE OF
THEIR RELATIVELY ATTRACTIVE PRICES. We remained focused on the large
international oil companies, such as Texaco (2%) and Exxon (3%), and oil service
companies, such as Baker Hughes (2%) and Schlumberger Limited (3%). Over the
next several years, we believe this sector will realize improved earnings due to
higher demand for its products and services.

WE INCREASED OUR EXPOSURE IN RETAIL STOCKS DUE TO THEIR ATTRACTIVE PRICES
COMPARED TO THE MARKET. Some of our top holdings in this sector included larger,
well-known retailers, such as The Limited (3%), which recently restructured its
operations by closing poorly performing stores, and Home Depot (0.7%), the
nation's largest store for home improvement equipment. Given their size, these
companies should benefit if the economy and consumer spending continue to
strengthen.

GROWTH AND INCOME FUND  (CONTINUED)
- --------------------------------------------------------------------------------

EARLY IN 1997, WE ADDED TO OUR POSITION IN ELECTRIC AND TELEPHONE UTILITIES,
GIVEN THEIR FAIR VALUATIONS*** AND ATTRACTIVE DIVIDEND YIELDS.*** Three of our
holdings in this sector include GTE (3%), BellSouth (2%) and FPL Group (2%). We
have a particularly favorable outlook for FPL Group. This large Florida electric
utility is likely to see earnings increase due to growth in its service
territory as well as disciplined expense control.

THE FUND'S UNDERWEIGHTING*** IN TECHNOLOGY STOCKS DETRACTED FROM PERFORMANCE IN
LATE 1996 BUT HELPED PROTECT SHAREHOLDER CAPITAL IN EARLY 1997. Technology
stocks recorded strong investment results in late 1996, following a difficult
period last summer, but during the first three months of 1997, many of these
stocks fell sharply as investors grew concerned over their lofty valuations
compared to the market. Late in the period, we began looking for attractively
priced stocks within this sector. Further weakness in this industry group may
encourage us to increase our exposure in some of the larger, more established
companies.

LOOKING AHEAD, WE WILL CONTINUE TO FOCUS ON LARGE, HIGH-QUALITY COMPANIES WITH
ATTRACTIVE VALUATIONS. Many companies have not participated in the strong stock
market over the past several years. We think the market will remain volatile
until the economic and inflation outlook becomes more certain. We continue to
believe the fund will benefit from its investments in the energy and utility
areas due to the market's uncertainty. Both groups are considered defensive
because of their relatively high dividend yields. We will also focus our
research efforts on finding companies in the technology and financial areas to
take advantage of the large price corrections*** that occurred within these
groups late in the period.

Thank you for your investment in Growth and Income Fund. We appreciate the
opportunity to manage your assets and help you pursue your long-term investment
goals.

Sincerely,

BALANCED FUND
- --------------------------------------------------------------------------------
May 15, 1997

DEAR SHAREHOLDERS:

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 1997, BALANCED FUND CLASS A REGISTERED
A 4.54%* TOTAL RETURN WITH ALL DIVIDENDS AND CAPITAL GAINS REINVESTED, BUT NOT
INCLUDING THE SALES CHARGE. The fund underperformed the Lipper Balanced Funds
Average,++ which gained 5.43%. For the same time period, the Standard & Poor's
500 Index+ and the Lehman Brothers Government Corporate Index** advanced 11.23%
and 2.17%, respectively. The fund's underperformance reflects our decision to
maintain a relatively conservative investment approach during the period. This
conservative 50%/50% blend of stocks and bonds was based on our assessment that
large company stocks were fully valued*** relative to bonds on a risk-adjusted
basis. We continue to believe this allocation strategy will benefit the fund in
the prevailing market environment.

THROUGHOUT MUCH OF THE PERIOD, ECONOMIC CONDITIONS WERE GENERALLY FAVORABLE. In
this environment, stocks recorded good investment results, while bonds produced
modest gains. Late in 1996, the economy grew moderately, which kept interest
rates under control, enabling bond and stock prices to advance. Beginning in
February, a series of stronger-than-expected economic reports, such as an
increase in consumer spending, raised inflation concerns among investors. As a
result, interest rates rose and

bond prices fell. By mid-March, these fears carried over to the stock market,
sending prices down sharply during the last three weeks of the month. In its
effort to combat fears of higher inflation, the Federal Reserve on March 25
raised the federal funds rate for the first time in two years.

IN THE STOCK PORTION OF THE PORTFOLIO, WE WERE OVERWEIGHTED*** IN ECONOMICALLY
SENSITIVE STOCKS, OR CYCLICALS.***  Generally, cyclicals, which include
companies that produce capital goods and basic materials, outperform the market
when the economy begins to show signs of strength. However, over the last three
years, these stocks have generally underperformed the market, and their prices
do not reflect the improvements we see in their fundamental businesses. Our
holdings in this group include Boeing Co. (approximately 1% of the fund's total
assets as of March 31, 1997), the nation's largest airplane manufacturer, and 3M
(0.8%), which manufactures Scotch tape, sandpaper and other products. These
stocks turned in generally favorable investment results, despite the lackluster
investment results recorded by cyclicals.

ENERGY STOCKS WERE WELL REPRESENTED IN THE FUND, BECAUSE OF THEIR RELATIVELY
ATTRACTIVE PRICES. Despite good performance by energy stocks in 1996, we believe
many are still selling at favorable prices. Our largest holdings in this group
include Exxon (1%), the world's leading oil company, Royal Dutch Petroleum
(0.8%), owners of Shell Oil Company, and Schlumberger Limited (1%), a leading
oil services company. Strong demand growth combined with limited supply
increases should support higher energy prices over the next several years.

WE MAINTAINED OUR OVERWEIGHTING IN RETAIL STOCKS, WHICH PERFORMED IN LINE WITH
THE MARKET. Lower unemployment, strong job growth, good wage gains and high
consumer confidence should support high levels of consumer spending. Sears,
Roebuck and Co. (1%) and The Limited (1%) are two of our larger holdings within
this group. In addition to offering good long-term growth, we believe the stocks
are undervalued*** and offer good dividend income.

BALANCED FUND  (CONTINUED)
- --------------------------------------------------------------------------------
IN THE BOND PORTION OF THE FUND, WE REALIZED GOOD INVESTMENT RESULTS FROM OUR
POSITION IN MORTGAGE-BACKED SECURITIES. These securities enjoyed strong
performance compared to other fixed income securities. With regard to
investment-grade corporate securities, we concentrated on bonds with short- to
intermediate-term maturities due to our assessment that these securities were
fairly priced. We maintained the fund's effective duration*** at approximately
five years, which is similar to that of our fixed income benchmark (the Lehman
Brothers Government Corporate Index). Our laddered portfolio structure*** had a
negligible impact on performance. If the economy continues to show unexpected
signs of strength in the coming months, interest rates could move higher.
However, since we don't expect rates to rise significantly, we intend to view a
further upward move as an opportunity to increase portfolio income by extending
the fund's effective duration.

GOING FORWARD, WE BELIEVE THE STRENGTH OF THE ECONOMY WILL HAVE A SIGNIFICANT
EFFECT ON THE STOCK AND BOND MARKETS. Further increases in interest rates are
likely to cause stock and bond prices to decline near-term, but we believe such
a development would be relatively short-lived. Federal Reserve Chairman Alan
Greenspan has a long history of fighting inflation and appears committed to
maintaining this philosophy in keeping future inflationary pressures under
control. Given our forecast, we intend to view future market downturns for both
stocks and bonds as excellent long-term buying opportunities.

Thank you for your investment in Growth and Income Fund. We appreciate the
opportunity to manage your assets and help you pursue your long-term investment
goals.

Sincerely,

/s/ Bruce Salvog                        /s/ Steve Markusen

(1) ORGANIZATION
 ................................
                      Piper Funds Inc. (the company) is registered under the
                      Investment Company Act of 1940 (as amended) as a single,
                      open-end management investment company. The company
                      currently has 12 series, including Growth and Income Fund
                      and Balanced Fund (the funds), each of which is classified
                      as a diversified series. The company's articles of
                      incorporation permit the board of directors to create
                      additional series in the future.
 
                      The funds commenced offering Class B shares and Growth and
                      Income Fund commenced offering Class Y shares on February
                      18, 1997. All shares existing prior to that date were
                      classified as Class A shares. Key features of each class
                      are:
 
                      CLASS A:
                      - Subject to a front-end sales charge
 
                      - Lower annual expenses than Class B
 
                      CLASS B:
                      - No front-end sales charge
 
                      - Subject to a contingent deferred sales charge upon
                      redemption
 
                      - Higher annual expenses than Class A
 
                      - Automatic conversion to Class A shares at the beginning
                      of the sixth calendar year after issuance
 
                      CLASS Y:
                      - Requires a minimum initial investment of $1 million or
                      more
 
                      - No front-end or contingent deferred sales charges
 
                      - Lower annual expenses than other classes
 
                      The classes of shares have the same rights and are
                      identical in all respects except that each class bears
                      different distribution expenses, has exclusive voting
                      rights with respect to matters affecting that class and
                      has different exchange privileges.
 
                      Growth and Income Fund invests primarily in stocks of
                      large, established companies that appear undervalued and
                      potentially offer long-term dividend and earnings growth.
                      The fund may also invest in debt securities, including
                      U.S. government securities and nonconvertible preferred
                      stock. On June 21, 1996, Growth and Income Fund acquired
                      all of the net assets of Hercules North American Growth
                      and Income Fund in a tax-free reorganization approved by
                      Hercules Funds' shareholders on June 18, 1996.

                      Balanced Fund invests in both common stocks and fixed
                      income securities that appear to have some potential for
                      capital appreciation.
 
(2) SUMMARY OF
    SIGNIFICANT
    ACCOUNTING
    POLICIES
 ................................
                      INVESTMENTS IN SECURITIES
                      Investments in securities traded on a national securities
                      exchange or on the Nasdaq National Market System are
                      valued at the last reported sales price that day.
                      Securities traded on a national securities exchange or on
                      the Nasdaq National Market System for which there were no
                      sales on that day and securities traded on other
                      over-the-counter markets for which market quotations are
                      readily available are valued at the mean of the bid and
                      asked prices. Exchange-traded options are valued at the
                      last sales price on the exchange prior to the time when
                      assets are valued. If no sales were reported that day, the
                      options will be valued at the mean between the current
                      closing bid and asked prices. 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.
 
                      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 New York Stock 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 or
                      dealers 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.
 
                      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.
                      Dividend income is recognized on the ex-dividend date and
                      interest income, including amortization of bond discount
                      and premium computed on a level-yield basis, is accrued
                      daily.
 
                      OPTIONS TRANSACTIONS
                      For hedging purposes, the funds may buy and sell put and
                      call options, write covered call options on portfolio
                      securities and write cash-secured puts. The risk in
                      writing a call option is that the funds give up the
                      opportunity of profit if the market price of the security
                      increases. The risk in writing a put option is that the
                      funds may incur a loss if the market price of the security
                      decreases and the option is exercised. The risk in buying
                      an option is that the funds pay a premium whether or not
                      the option is exercised. The funds also have the
                      additional risk of not being able to enter into a closing
                      transaction if a liquid secondary market does not exist.
 
                      Option contracts are valued daily and unrealized
                      appreciation or depreciation is recorded. The funds will
                      realize a gain or loss upon expiration or closing of the
                      option transaction. When an option is

                      cost of a security for purchased put and call options is

</TABLE>
 
                      FUTURES TRANSACTIONS
                      For hedging purposes, the funds may buy and sell financial
                      futures contracts and related options. Risks of entering
                      into 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 when-issued or
                      forward-commitment 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. The funds segregate, with their custodian,
                      assets with a market value equal to the amount of their
                      purchase commitments. The purchase of securities on a
                      when-issued or forward-commitment basis may increase the
                      volatility of the fund's net asset value if the funds make
                      such purchases while remaining substantially fully
                      invested. As of March 31, 1997, 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" and
                      "straddle" transactions and the non-deductibility of
                      amortization of organization costs.
 
                      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. Distributions which exceed the net investment
                      income or net realized gains for financial statement
                      purposes are presented as an "excess distribution" in the
                      statements of changes in net assets and the financial
                      highlights. 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 separately for each class and paid quarterly.
                      Net realized gains distributions, if any, will be made at
                      least annually. Distributions are payable in cash or
                      reinvested in additional shares of the same class.
 
                      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 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.
 
                      ORGANIZATION COSTS
                      Organization costs were incurred in connection with the
                      start up and initial registration of the funds. These
                      costs are amortized over 60 months on a straight-line
                      basis. If any or all of the shares representing initial
                      capital of the fund are redeemed by any holder thereof
                      prior to the end of the amortization period, the proceeds
                      will be reduced by the unamortized organization cost
                      balance in the same proportion as the number of shares
                      redeemed bears to the number of initial shares outstanding
                      preceding the redemption.
 
                      ALLOCATION OF INCOME, EXPENSES, AND GAINS AND LOSSES
                      Income, expenses (other than class-specific expenses) and
                      realized and unrealized gains and losses are allocated
                      daily to each class of shares based upon the relative
                      proportion of net assets represented by such class.
                      Class-specific expenses, which include distribution and
                      service fees, are charged directly to such class.
 
                      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 in the financial statements. Actual
                      results could differ from these estimates.

(5) EXPENSES
 ................................
                      INVESTMENT MANAGEMENT FEE
                      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 0.75% of the first $100 million in
                      net assets, 0.65% of the next $200 million and decreasing
                      percentages thereafter to 0.50% of net assets in excess of
                      $500 million.
 
                      DISTRIBUTION AND SERVICE FEES
                      Each fund also pays Piper Jaffray fees accrued daily and
                      paid quarterly for providing shareholder services and

                      OTHER FEES AND EXPENSES
                      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. For the year ending September 30,
                      1997, Piper Capital voluntarily limited total fees and
                      expenses for Growth and Income Fund to annual rates of
                      1.34%, 2.00% and 1.00% of average daily net assets
                      attributable to such shares for Class A, Class B and Class
                      Y, respectively, and for Balanced Fund to annual rates of
                      1.34% and 2.00% of average daily net assets attributable
                      to such shares for Class A and Class B, respectively.
 
                      Expenses paid indirectly represent a reduction of
                      custodian fees for earnings on miscellaneous cash balances
                      maintained by the funds.

SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------

As a shareholder in Piper Funds, you have access to a full range of services and
benefits.

Check your prospectus for details about services and any limitations that might
apply to your fund.

LOW MINIMUM INVESTMENTS
You can open a Piper Fund account with a minimum investment of $250.

QUANTITY DISCOUNTS
If your initial investment exceeds a specified amount, if an investment combined
with the value of your existing Piper shares exceeds a specified amount, or if
your investments combined during a 13-month period exceed a specified amount,
you can reduce or even eliminate the front-end sales charge.

WAIVER OF SALES CHARGES
Money market funds carry no sales charges.* Sales charges on other Piper Funds
are waived on purchases of $500,000 or more. However, a contingent deferred
sales charge may be imposed. See your prospectus for details.

AUTOMATIC REINVESTMENT OF DISTRIBUTIONS
For maximum growth of your assets, you can reinvest dividends and capital gains
automatically in additional shares of your fund without a sales charge.

CROSS-REINVESTMENT OF DISTRIBUTIONS
Diversify your holdings by reinvesting dividends and capital gains from one
Piper Fund to another.

CASH DISTRIBUTIONS
If you prefer, take your dividends and/or capital gains in cash.

AUTOMATIC MONTHLY INVESTMENT PROGRAM
You may automatically transfer $25 or more each month from any Piper money
market fund* into many other Piper Funds.

AUTOMATIC MONTHLY MONEY TRANSFER PROGRAM
If you are starting a savings discipline or seeking a convenient way to invest,
you can transfer a minimum of $100 automatically from your bank, savings and
loan or other financial institution into many of the Piper Funds.

EXCHANGE PRIVILEGES
Revise your investment plan without incurring a sales charge by moving assets
from one Piper Fund to another with the same fee structure. See your prospectus
for restrictions involving exchanges between funds with different sales charges.

REINVESTMENT PRIVILEGES
If you buy a fund with a sales charge and later redeem your shares, you may
reinvest all or part of the proceeds in shares of that fund or another Piper
Fund within 30 days and pay no additional sales charge, subject to each fund's
minimum investment requirements.

SYSTEMATIC WITHDRAWAL PLAN
If your account has a value of $5,000 or more, you can elect to receive periodic
payments of $100 or more, at no cost, excluding money market funds.

ACCOUNT STATEMENTS
Whenever you add to or withdraw money from your account, you'll receive a
monthly statement from Piper Jaffray. Accounts with no activity receive a
quarterly statement instead. Periodic dividend and capital gain distributions,
if any, also appear on your statement.

CONFIRMATION OF TRANSACTIONS
You receive a confirmation statement following every transaction, except in the
money market funds. All transactions are reflected on your account statement.

* An investment in a Piper money market fund is neither insured nor guaranteed
by the U.S. government, and there can be no assurance that the fund will be able
to maintain a stable net asset value of $1 per share.

GLOSSARY OF TERMS
- --------------------------------------------------------------------------------

BLUE-CHIP STOCK
Stock of a nationally-known company with a long record of profit growth and
dividend payment and a reputation for quality management, products and services.

CORRECTION
A reverse movement (usually downward)in the price of a security.

CYCLICAL STOCKS
Shares of companies that are highly dependent on the state of the economy (also
called economically sensitive stocks). When the economy slows, their earnings
generally fall rapidly, and typically, so does the stock price. But when the
economy recovers, earnings generally rise rapidly, and the price of the stock
typically goes up.

DIVIDEND YIELD
The annual percentage rate of return paid on a stock in the form of dividends.

EFFECTIVE DURATION
Effective duration estimates how much the value of a security is expected to
change with a given change in interest rates. Longer effective durations
indicate more sensitivity to changes in interest rates. For example, if interest
rates were to increase 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 remember that effective duration is based on
certain assumptions and has several limitations. It is most effective as a
measure when interest rate changes are small, rapid and occur equally across all
the different points of the yield curve. In addition, effective duration is
difficult to calculate precisely for bonds with prepayment options, such as
mortgage-backed securities.

FULLY VALUED
A stock is considered fully valued if it has reached a price at which analysts
think the underlying company's fundamental earnings power has been recognized by
the market. If the stock goes up from that price, it is called overvalued. If it
goes down, it is termed undervalued.

LADDER PORTFOLIO STRUCTURE
Emphasizes securities with maturities on many different points on the yield
curve. (The yield curve is a graph that shows the relationship between the
interest rates paid on bonds and their maturities, ranging from the shortest
maturities to the longest available -- assuming the bonds are all of the same
quality. The resulting curve indicates whether short-term interest rates are
higher or lower than long-term rates.)

OVERWEIGHTED OR OVERWEIGHTING
In portfolio management, overweighting means a fund's portfolio contains a
higher percentage of a certain sector than its benchmark.

OVERVALUED
A security is overvalued if it is selling at a price higher than what analysts
believe it is worth.

SECTOR
Refers to a particular group of stocks, usually in one industry.

UNDERVALUED
A security is undervalued if it is selling at a price lower than what analysts
believe it is worth.

UNDERWEIGHTED OR UNDERWEIGHTING
In portfolio management, underweighting means a fund's portfolio contains a
lower percentage of a certain sector than its benchmark.

VALUATION
The determined or estimated value of a particular stock.
