*Past performance does not guarantee future results. Keep in mind that stocks
are more volatile than bonds, and long-term government bonds are guaranteed by
the U.S. government or its agencies as to payment of principal and interest. 

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

DEAR SHAREHOLDERS:

EMERGING MARKETS GROWTH FUND CLASS A RETURNED 12.94%* FOR THE SIX-MONTH PERIOD
ENDED MARCH 31, 1997, WHICH INCLUDES REINVESTED DISTRIBUTIONS BUT NOT THE FUND'S
SALES CHARGE. This compares to a 7.83% return for the MSCI Emerging Markets Free
Index+ and an 11.08% return for the Lipper Emerging Markets Funds Average++ over
the same time period. The fund's strong performance compared to the index and
the average was largely due to our overweighted*** position in Latin America,
which recorded solid investment results. 

DURING THE FIRST THREE MONTHS OF THE PERIOD, THE LATIN AMERICAN MARKETS TRENDED
LOWER BUT THEN RECORDED EXCELLENT RESULTS IN JANUARY AND FEBRUARY BEFORE
RETREATING IN MARCH. Economic conditions continued to improve in the region. In
Mexico, for example, inflation declined, while the economy, bolstered by rising
industrial production, showed clear signs of strength. Rising industrial
production and political stability helped other key markets in the region, most
notably Brazil and Argentina.    

THE BEST PERFORMING MARKET IN LATIN AMERICA WAS BRAZIL, FOLLOWED BY ARGENTINA
AND COLOMBIA. The solid performance in Brazil was due to the acceleration of the
country's privatization program and significant tariff increases for
telecommunications and electricity companies. One of our better

characterized by Lipper Analytical Services.

Class A Average Annualized Total Returns
Includes the fund's maximum 4% front-end sales charge.

One Year                     20.85%
- --------------------------------------------------------------------------------
Three Year                   -4.13%

Class B Cumulative Total Returns
Includes the fund's contingent deferred sales charge.

Since Inception (2/18/97)    -5.42%
- --------------------------------------------------------------------------------

During some periods, the fund's adviser waived or paid certain fund expenses
and/or the fund's distributor voluntarily limited certain 12b-1 fees for the
fund. Otherwise, the class A average annualized total returns would have been:
19.04% one year, -5.45% three year and -2.57% since inception; and the class B
cumulative since inception total return would have been -6.65%.

* 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. PLEASE REMEMBER, YOU COULD
LOSE MONEY WITH THIS INVESTMENT. SAFETY OF PRINCIPAL IS NOT GUARANTEED. 

The fund operated as Hercules Latin American Value Fund until June 21, 1996. Up
to that point, it invested only in Latin American securities.


All fund and benchmark returns include reinvested distributions.

performing stocks in Brazil was Telebras, a major telecommunications provider
(as of March 31, 1997, this stock represented 4% of the fund's total assets). In
1996 alone, the stock advanced approximately 60% due to a sharp increase in
earnings. Telebras also continued to benefit from deregulation and privatization
in Brazil. Strong cash flows into the newly established pension funds helped
bolster the Argentinian stock market. Colombia rallied on improving political
and economic conditions.

DURING THE PERIOD, THE FUND BROADENED ITS EXPOSURE TO TAKE ADVANTAGE OF
INVESTMENT OPPORTUNITIES IN SOUTHEAST ASIA, EASTERN EUROPE AND AFRICA. Several
companies in these regions appear to have excellent earnings growth prospects
and are still selling at attractive valuations*** relative to stocks in mature
markets. Moreover, the economies in which they operate are growing at a healthy
rate. Two examples include NMBZ Holdings (0.8%), a national merchant bank in
Zimbabwe, and Sasol (2%), a South African synthetic oil company. To expand into
these areas, we used new cash inflows into the fund and the sale of Latin
American stocks that met our target prices.  

IN MARCH, THE FUND SLOWED ITS BUYING PROGRAM IN SOUTHEAST ASIA, EASTERN EUROPE
AND AFRICA AND SLIGHTLY INCREASED ITS CASH POSITION BY TAKING ADDITIONAL PROFITS
IN LATIN AMERICAN STOCKS. The move was due to the downturn in the U.S. financial
markets because of stronger-than-expected domestic economic growth and its
effect on most overseas markets. The fund's above-average cash position late in
the period helped protect shareholder capital during this period.

EMERGING MARKETS GROWTH FUND  (CONTINUED)
- --------------------------------------------------------------------------------

OUR FORECAST FOR EMERGING MARKETS REMAINS POSITIVE. On balance, economies are
expanding at a healthy pace, earnings growth rates are strong, and the political
landscape appears stable. Given the correction*** that took place in Latin
American markets in 1995 and the downturn in many Pacific Basin markets in 1996,
prices of many stocks are also attractive. The same can be said for valuations
in our other principal areas of investment, namely Eastern Europe and North
Africa. We expect interest rates in Mexico, Brazil and Chile to fall as
inflation declines. Lower interest rates should benefit corporate earnings. We
don't believe China's takeover of Hong Kong in July will have a negative impact
on financial markets in southeast Asia. In fact, a non-eventful takeover may be
viewed positively by investors. While the strength of the U.S. economy may cause
continued volatility in the domestic markets, we don't anticipate significant
performance correlation between U.S. securities and the fund's current holdings.

Thank you for your investment in the Emerging Markets Growth Fund. We consider
it a privilege to manage your money and remain dedicated to helping you pursue
your long-term financial goals through superior investment results.

Sincerely,

/s/ Richard Muckart

DEAR SHAREHOLDERS:

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 1997, PACIFIC-EUROPEAN GROWTH FUND
CLASS A PRODUCED A TOTAL RETURN OF -1.55%,* WHICH INCLUDES REINVESTED
DISTRIBUTIONS BUT NOT THE FUND'S SALES CHARGE. Over the same
time frame, the MSCI European, Australian, Far East (EAFE) Index+, the fund's
benchmark,*** returned 0.15% and the Lipper International Funds Average++
returned 5.33%. Our underperformance was due largely to our overweighting***
in the Pacific Basin and our underweighting*** in Europe. For the period,
European markets significantly outperformed their Pacific Basin counterparts.

POOR PERFORMANCE BY JAPANESE STOCKS HAD A NEGATIVE IMPACT ON THE FUND'S
INVESTMENT RESULTS. Weakness in the Japanese market was due to several factors.
Investors were concerned over the 1997 draft budget, which requires fiscal
tightening to curb government debt. A slowing economy also affected performance.
After showing signs of an improving economy early in 1996, Japan's economy
slowed late in the year and into 1997. Additionally, problems within the
country's banking system had a significantly negative effect on stock prices.
Two holdings in the fund that recorded disappointing results were FUJI Bank (1%
of total assets as of March 31) and Topre (0.5%), an automotive parts

AHEAD OF THE DECLINE IN JAPANESE STOCKS, THE FUND ADOPTED A DEFENSIVE STANCE BY
REDUCING ITS ASSET ALLOCATION*** IN JAPAN FROM 46% OF TOTAL ASSETS ON
SEPTEMBER 30, 1996, TO 29% ON MARCH 31, 1997. This strategy reduced the impact
of Japan's stock market performance on the fund's investment results. Despite
Japan's problems, the fund enjoyed good performance from blue-chip***
companies there, namely Matsushita Electric Works (0.8%), Hitachi (2%) and
Murata Manufacturing (2%). Since these companies have significant business
interests in other countries, they are less affected by local market and
economic conditions than most other Japanese companies. 

CONTINENTAL EUROPEAN MARKETS PRODUCED SOLID RETURNS, BUT WEAKNESS IN THE DOLLAR
CUT SLIGHTLY INTO THOSE GAINS. Strength in Europe was largely due to a generally
improving economic environment. Germany and Switzerland were two of the better
performing markets. The fund received good investment results from Bayer (2%),
one of the world's largest chemical companies; electronics and communications
giant Siemens (1%); Swiss-based Nestle (2%); and French oil giant Total (2%).
Due to the Easter holidays, the late-quarter decline in U.S. stocks was not
fully reflected in European markets. In March, the fund maintained a defensive
investment posture by emphasizing value stocks in both the Pacific Basin and
European markets. These stocks tend to fare better than growth stocks when
markets trend lower.

PACIFIC BASIN MARKETS RECORDED MIXED INVESTMENT RESULTS. For example, while Hong
Kong and Indonesia recorded double digit percentage increases, Singapore, Korea
and Thailand turned in double digit percentage losses. In February, Deng
Xiaoping's death had little impact on Hong Kong and other Chinese related
markets. Some of the fund's better performing stocks included Hutchison Whampoa
(0.8%), an industrial conglomerate in Hong Kong, and Bank International
Indonesia (0.4%), the third largest public bank in Indonesia.

DURING THE PERIOD, THE FUND ENJOYED ATTRACTIVE INVESTMENT RESULTS FROM ITS SMALL
POSITION IN LATIN AMERICA. The best performing market in the region was Brazil,
followed by Colombia and Argentina. Improving economic conditions in key markets
were largely responsible for the gains. In Mexico, for example, inflation
declined, while the economy, bolstered by rising industrial production, showed
clear signs of strength. Rising industrial production and political stability
helped Brazil and Argentina. Due to the uncertainty in the U.S. financial
markets and its potential impact on some markets in the region, the fund reduced
its exposure to Latin America late in the period by selling stocks that had
already reached their price targets for 1997.

LOOKING AHEAD, OUR NEAR-TERM FORECAST FOR JAPAN REMAINS CAUTIOUS. While Japan's
banking difficulties are likely to continue in the coming months, we believe the
potential long-term impact of these problems has been overstated. Just as U.S.
banks overcame their financial woes in the early 1990s, we expect Japanese banks
will inevitably rise beyond their difficulties. Although Japanese bank stocks

not attractive to us now, our opinion could change once their values begin to
firm and the local economy starts to show clear signs of a sustainable rebound. 

AS FOR CONTINENTAL EUROPE AND THE PACIFIC BASIN, OUR OUTLOOK REMAINS FAVORABLE.
From a macro-perspective, several structural developments in these regions bode
well for financial assets. For example, an increasing number of industries are
shifting from government to private control, and entire economies are opening
their markets and eliminating centralized management. Moreover, valuations***
are still attractive, corporate earnings growth remains strong and interest
rates are under control. In the coming months, uncertainty in the U.S. financial
markets is likely to affect some non-U.S. markets. Longer-term, however, we
believe the strong fundamentals underpinning most European and Pacific Basin
economies will be beneficial to stocks in these regions.  

We appreciate your investment in the Pacific-European Growth Fund and will do
our best to deliver improved performance in pursuit of the fund's investment
objective.

Sincerely,

/s/ Richard Muckart

(1) ORGANIZATION
 ................................
                      Piper Global 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 outstanding two series (the funds):
                      Emerging Markets Growth Fund is a non-diversified series
                      and Pacific-European Growth Fund is 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
                      Pacific-European Growth Fund commenced offering Class Y
                      shares on February 18, 1997. All shares existing prior to
                      this 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 year after issuance
 
                      CLASS Y:
                      - Requires an 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.
 
                      Emerging Markets Growth Fund invests primarily in common
                      stocks of companies in the world's emerging securities
                      markets. Emerging Markets Growth Fund commenced operations
                      and acquired the net assets of Hercules Latin American
                      Value Fund, a series of Hercules Funds Inc., on June 21,
                      1996, via a tax-free reorganization. Emerging Markets
                      Growth Fund had no assets or liabilities prior to the
                      acquisition. Consequently, the information presented for
                      Emerging Markets Growth Fund prior to June 21, 1996
                      represents the financial history of Hercules Latin
                      American Value Fund.

 ................................
                      INVESTMENTS IN SECURITIES
                      Investments in securities traded on a U.S. or foreign
                      securities exchange or included in a national market
                      system are valued at the last quoted sales price.
                      Securities for which there were no sales reported on that
                      day are valued at the mean of the bid and asked prices. In

- --------------------------------------------------------------------------------
                      quotations are not readily available and in certain other
                      circumstances, fair value is determined according to
                      methods selected 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 or
                      upon receipt of ex-dividend notification in the case of
                      certain foreign securities. 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 exercised, the
                      proceeds on the sale of a written call option, the
                      purchase cost of a written put option, or the cost of a
                      security for purchased put and call options is adjusted by
                      the amount of premium received or paid.
 
                      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.
 
                      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 tax.

                      Net investment income and net realized gains (losses) may
                      differ for financial statement and tax purposes primarily
                      because of the recognition of certain foreign currency
                      gains (losses) as ordinary income (loss) for tax purposes,
                      the "mark-to-market" of certain Passive Foreign Investment
                      Companies (PFICs) for tax purposes, the "mark-to-market"
                      of certain investments for tax purposes, losses deferred
                      due to "wash sale" 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. 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 at least
                      annually. Net realized gains distributions, if any, are
                      made at least annually. Distributions are payable in cash
                      or reinvested in additional shares of the same class.
 
                      ORGANIZATION COSTS
                      Organization costs were incurred in connection with the
                      start up and initial registration of Emerging Markets
                      Growth Fund's predecessor. 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.
 
                      FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS
                      Securities and other assets and liabilities denominated in
                      foreign currencies are translated into U.S. dollars at the
                      closing rate of exchange. Foreign currency amounts related
                      to the purchase or sale of securities and income and
                      expenses are translated at the exchange rate on the
                      transaction date. For financial reporting purposes the
                      realized and unrealized gain (loss) on investments
                      reflects changes in exchange rates as well as changes in
                      the market value of investments.
 
                      The funds also may enter into forward foreign currency
                      exchange contracts for hedging purposes. The net U.S.
                      dollar value of foreign currency underlying all
                      contractual commitments held by the funds, and the
                      resulting unrealized appreciation or depreciation, are
                      determined using foreign currency exchange rates from
                      independent pricing sources. The funds are subject to the
                      credit risk that the other party will not complete the
                      obligations of the contract.
 
                      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.

                      repurchase agreements are held by the 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.
 
                      ALLOCATION OF INCOME, EXPENSES, 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.
 
                      CONCENTRATION OF RISK
                      Investments in countries with limited or developing
                      capital markets may involve greater risks than investments
                      in more developed markets and the prices of such
                      investments may be volatile. The consequences of
                      political, social or economic changes in these markets may
                      have disruptive effects on the market prices of the funds'
                      investments and the income they generate, as well as the
                      funds' ability to repatriate such amounts.
 
                      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.

(6) 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 the
                      funds' 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. For Emerging Markets Growth Fund
                      the fee is equal to an annual rate of 1% of the fund's
                      average daily net assets. For Pacific-European Growth
                      Fund, the fee is equal to an annual rate of 1% on the
                      first $100 million in average daily net assets, 0.875% of
                      the next $100 million and 0.75% of the net assets in
                      excess of $200 million.
 
                      Since April 1991, the basic fee for Pacific European
                      Growth Fund has been subject to a performance adjustment.
                      The adjustment is computed monthly by comparing the
                      performance of the fund relative to the Morgan Stanley
                      Capital International EAFE Index, over the preceding 12
                      month period. For each percentage point the fund
                      outperforms or underperforms the EAFE Index the monthly
                      fee is

                      March 31, 1997, the performance adjustment decreased the
                      management fee by $153,582.

                      Capital as the subadviser of Pacific-European Growth Fund
                      and is paid a fee equal to 65% of the basic investment
                      management fee plus or minus 90% of the performance
                      adjustment. Edinburgh Fund Managers plc has entered into

                      the basic investment management fee. This 10% fee is a
                      reimbursement to the adviser for certain expenses it bears
                      in connection with the administration of Pacific-European
                      Growth Fund. Edinburgh Fund Managers plc has been retained

                      offset by subsequent capital gains, will expire as noted.

                      $2,190,585 of net realized gains could not be offset by
                      these capital loss carryovers during the seven months
                      ended September 30, 1996. The utilization of these capital
                      loss carryovers is limited to $1,065,056 per year.

                                 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
