                                                    222 SOUTH NINTH STREET
                                                    MINNEAPOLIS, MN 55402-3804
 
May 17, 1996
 
Dear Shareholder:
 
A special meeting of shareholders of Hercules European Value Fund (the "Fund")
will be held at the offices of Hercules Funds Inc. on June 18, 1996 at 10 a.m.
central time at 222 South Ninth Street, 3rd floor, Minneapolis, Minnesota.
 
This meeting has been called to seek shareholder approval to combine the assets
of the Fund with assets of Pacific-European Growth Fund, a series of Piper
Global Funds Inc. If approved, Fund shareholders would become shareholders of
Pacific-European Growth Fund and would receive shares with a value equal to the
value of their Fund shares.
 
This reorganization is part of a larger proposal to eliminate Hercules as a
separate family of funds, as we believe the funds are unlikely to grow to a size
which is economically viable. If you are a shareholder in more than one Hercules
fund, you will receive separate mailings of proxy materials for each fund.
PLEASE RETURN A COMPLETED PROXY CARD FOR EACH FUND IN WHICH YOU ARE INVESTED.
 
We urge you to read all of the enclosed materials carefully but direct your
attention to the following important points:
 
    - The Board of Directors of the Company has unanimously approved the
      reorganization and recommends that you vote FOR the reorganization.
 
    - Shareholders will not incur any commissions, sales loads or other charges
      in connection with the reorganization and Piper Capital, the investment
      manager for both funds, has agreed to pay for all direct expenses
      including the proxy solicitation.
 
    - Edinburgh Fund Managers plc, an experienced international investment
      manager, is the subadviser to Pacific-European Growth Fund.
 
    - The expense ratio for Pacific-European Growth Fund is lower than the
      Fund's expense ratio. While waivers and reimbursements currently keep the
      Fund's expense ratio artificially low, Piper Capital and the Fund's
      distributor do not presently intend to continue waiving expenses for the
      Fund after June 30, 1996.
 
    - The reorganization would enable Fund shareholders to enjoy an expanded
      range of mutual fund investment options, including 16 other open-end Piper
      Funds. Shareholders who receive Pacific-European Growth Fund shares in the
      reorganization would have exchange privileges within the Piper family of
      funds.
 
    - The reorganization will not result in any federal taxable income to the
      Fund or its shareholders.
<PAGE>
PLEASE MARK, SIGN, DATE AND RETURN THE ENCLOSED PROXY CARD AS SOON AS POSSIBLE,
AS YOUR PROMPT RESPONSE WILL ELIMINATE THE NEED FOR ADDITIONAL MAILINGS. A
postage-paid envelope is enclosed with each proxy mailing for your convenience.
As the meeting date approaches, if you haven't voted you may receive a telephone
call reminding you to vote.
 
The enclosed QUESTION AND ANSWER sheet provides more detailed information about
the proposal. Also enclosed are the formal Notice of Special Meeting and Proxy
Statement/Prospectus documents. If you have additional questions, please contact
your investment professional or call Piper Capital at 1 800 866-7778 and press

Sincerely,
 
            [SIG]

SHAREHOLDER Q&A
 
                                                                    MAY 17, 1996
- --------------------------------------------------------------------------------
 
ON FEBRUARY 6, 1996, PIPER CAPITAL MANAGEMENT INCORPORATED RECOMMENDED TO THE
BOARD OF DIRECTORS OF HERCULES FUNDS INC. THAT IT ELIMINATE HERCULES AS A
SEPARATE FUND FAMILY BECAUSE THE FUNDS ARE TOO SMALL TO BE ECONOMICALLY VIABLE.
THE BOARD UNANIMOUSLY AGREED THAT IT WOULD BE IN THE BEST INTEREST OF
SHAREHOLDERS TO REORGANIZE THE HERCULES EQUITY FUNDS INTO APPROPRIATE PIPER
FUNDS AND TO LIQUIDATE THE WORLD BOND FUND. THESE PROPOSALS ARE SUBJECT TO
SHAREHOLDER APPROVAL.
 
WHAT WILL HAPPEN TO THE VARIOUS HERCULES FUNDS?
 
Piper Capital is proposing the following changes:
 
    - Hercules North American Growth and Income Fund will be reorganized into
      Growth and Income Fund, a series of Piper Funds Inc.
 
    - Hercules European Value Fund and Hercules Pacific Basin Value Fund will be
      reorganized into Pacific-European Growth Fund, a series of Piper Global
      Funds Inc.
 
    - Hercules Latin American Value Fund will be reorganized into the Emerging
      Markets Growth Fund, a newly-created series of Piper Global Funds Inc.
 
    - Hercules World Bond Fund will be liquidated and net assets distributed to
      shareholders.
 
WHAT ABOUT HERCULES MONEY MARKET FUND?
 
We expect that shareholders will redeem out of Hercules Money Market Fund as a
result of Piper Capital's decision to discontinue the fund's 1% expense
limitation effective July 1, 1996.
 
WHY WERE THESE CHANGES RECOMMENDED?
 
The Hercules funds have not been able to attract sufficient assets to make them
economically viable to operate and prospects for future growth appear remote. If
the changes are approved, we believe shareholders will benefit from:
 
    - A potential increase in operating efficiencies and therefore a reduction
      in expense ratios
 
    - The potential for greater investment diversification and more flexibility
      in portfolio management because the existing corresponding Piper funds
      have a larger asset base
 
    - The advantages of ownership within a larger fund family, including
      flexibility to transfer between funds in the Piper funds complex at net
      asset value
 
WILL SHAREHOLDERS PAY A SALES CHARGE WHEN THEY MOVE INTO THE PIPER FUNDS?
 
No. Even though Hercules shareholders paid no front-end sales charges, the
maximum 4% front-end load on Piper fund shares acquired in the reorganizations
will be waived if the proposal is approved.
 
WILL THE HERCULES CONTINGENT DEFERRED SALES CHARGE (CDSC) BE WAIVED?
 
Yes. Shareholders subject to a CDSC (those who purchased shares after June 19,
1995) will not pay a CDSC if they exchange into the respective Piper fund
through the reorganization.
 
WILL SHAREHOLDERS BE ABLE TO EXCHANGE OR TRANSFER TO OTHER PIPER OPEN-END FUNDS
AT NET ASSET VALUE?
 
Yes. After Hercules fund shares are reorganized into the applicable Piper fund,
shareholders will then be able to exchange or transfer into other Piper funds at
net asset value.
 
HOW MANY OTHER PIPER OPEN-END FUNDS ARE AVAILABLE?
 
The back side of the enclosed brochure lists the 16 other funds available in
Piper's family of open-end funds.
<PAGE>
WHAT PERCENTAGE OF SHAREHOLDERS MUST VOTE "YES" FOR THE PROPOSAL TO PASS?
 
For each fund, shareholders representing a majority of the outstanding shares
must vote yes in order for the proposed reorganization or liquidation of that
fund to occur.
 
IF APPROVED, HOW WILL THE REORGANIZATIONS BE ACCOMPLISHED?
 
The reorganizations would be accomplished by combining substantially all of the
assets of each fund with the corresponding Piper fund and distributing shares of
the Piper fund with a value equal to the value of each Hercules shareholder's
fund holdings.
 
WHO WILL PAY FOR THE REORGANIZATION?
 
Piper Capital has agreed to pay all direct costs associated with the proposed
reorganizations and liquidation including the costs of proxy solicitation. No
commission, sales loads or other charges will be incurred by shareholders. Also,
we anticipate the proposed reorganizations would be completed on a tax-free
basis.

GROWTH FUND?

    This  Proxy  Statement/Prospectus  is  being  furnished  to  shareholders of
Hercules European Value Fund (the "Fund"), a series of Hercules Funds Inc.  (the
"Company"),  in connection with an Agreement and Plan of Reorganization dated as
of April 15, 1996 (the "Plan") pursuant to which substantially all of the assets
of the  Fund  will  be  combined with  those  of  Pacific-European  Growth  Fund
("Pacific-European Fund"), a series of Piper Global Funds Inc. ("Piper Global"),
in   exchange  for  shares  of  Pacific-European  Fund.  As  a  result  of  this
transaction,  shareholders   of   the   Fund   will   become   shareholders   of
Pacific-European  Fund and will  receive shares of  Pacific-European Fund with a
value equal to the  value of their holdings  in the Fund as  of the date of  the
transaction.  The  terms  and  conditions of  this  transaction  are  more fully
described in this Proxy Statement/Prospectus and in the Plan, attached hereto as
EXHIBIT A.
 
    Pacific-European Fund is a diversified  series of Piper Global, an  open-end
management  investment company the shares  of which can be  offered in more than
one series.  The  investment objective  of  Pacific-European Fund  is  long-term
capital   appreciation.  Current   income  is  incidental   to  this  objective.
Pacific-European Fund seeks  to achieve  its investment  objective by  investing
primarily  in Common Stock (as herein defined) of companies in the Pacific Basin
or in Europe (including  Eastern Europe). Up to  25% of Pacific-European  Fund's
total  assets  may  be  invested in  other  areas  of the  world  to  the extent
significant opportunities  for long-term  capital  appreciation outside  of  the
Pacific Basin and Europe become available. Pacific-European Fund does not invest
in Common Stock of U.S. companies.
 
    This  Proxy  Statement/Prospectus  sets  forth  concisely  information about
Pacific-European Fund that shareholders of the Fund should know before voting on
the Plan. This Proxy Statement also constitutes a Prospectus of Pacific-European
Fund filed with  the Securities  and Exchange Commission  (the "Commission")  as
part  of its Registration Statement  on Form N-14. A  copy of the Prospectus for
Pacific-European  Fund  dated  April  28,  1995,  is  attached  to  this   Proxy
Statement/Prospectus  and is incorporated herein by reference. Also enclosed and
incorporated by reference is  Piper Global's Annual Report  for the fiscal  year
ended  February 29, 1996. A Statement  of Additional Information relating to the
reorganization described  in this  Proxy Statement/Prospectus  (the  "Additional
Statement")  dated May 2, 1996,  has been filed with  the Commission and is also
incorporated herein by reference. Also incorporated herein by reference are  the
Company's  Prospectus dated August 29, 1995, the Company's Annual Report for its
fiscal year ended June 30, 1995 and the Company's Semi-Annual Report for the six
months ended December 31, 1995. Such documents are available without charge,  as
noted under "Available Information" below.
 
  INVESTORS ARE ADVISED TO READ AND RETAIN THIS PROXY STATEMENT/PROSPECTUS FOR
                               FUTURE REFERENCE.
 
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
        EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS

GENERAL

Piper  Global,  as a  group, owned  less than  1% of  the outstanding  shares of
Pacific-European Fund.

PROXIES
 
    The enclosed form of proxy, if properly executed and returned, will be voted
in accordance with  the choice  specified thereon. The  proxy will  be voted  in
favor  of the Plan  unless a choice is  indicated to vote  against or to abstain
from voting on the  Plan. The Board  knows of no business,  other than that  set
forth in the Notice of Special Meeting, to be presented for consideration at the
Meeting.  However, the  proxy confers  discretionary authority  upon the persons
named therein  to  vote as  they  determine  on other  business,  not  currently
contemplated, which may come before the Meeting.
 
    Abstentions will be included for purposes of determining whether a quorum is
present at the Meeting and for purposes of calculating the vote but shall not be
deemed  to have been voted in favor of such matters. Broker non-votes are shares
held in street name  for which the broker  indicates that instructions have  not
been  received from the beneficial owners or  other persons entitled to vote and
for which  the  broker does  not  have discretionary  voting  authority.  Broker
non-votes  will  be included  for purposes  of determining  whether a  quorum is
present at the Meeting, but will not be deemed to be represented at the  Meeting
for purposes of calculating whether matters to be voted upon at the Meeting have
been  approved. Because approval of  the Plan requires an  affirmative vote by a
majority of the outstanding  shares, abstentions and  broker non-votes all  have
the same effect as a negative vote.
 
    If a shareholder executes and returns a Proxy Card but fails to indicate how
the  votes should be  cast, the proxy  will be voted  in favor of  the Plan. The
proxy may be revoked at any time prior to the voting thereof by: (i)  delivering
written  notice of revocation to the Secretary of the Company at 222 South Ninth
Street, Minneapolis, Minnesota 55402-3804; (ii) attending the Meeting and voting
in person; or  (iii) signing and  returning a  new Proxy Card  (if returned  and
received  in time  to be voted).  Attendance at the  Meeting will not  in and of
itself revoke a proxy.
 
    In the event that sufficient votes to  approve the Plan are not obtained  by
the  Meeting date, or, subject  to approval of the  Board, for other reasons, an
adjournment or adjournments of the Meeting may be sought. Any adjournment  would
require  a vote in favor of the adjournment  by the holders of a majority of the
shares present  at the  Meeting (or  any adjournment  thereof) in  person or  by
proxy.  The persons named as proxies will vote all shares represented by proxies
which they  are  required  to  vote  in  favor of  the  Plan,  in  favor  of  an
adjournment,  and will vote all  shares which they are  required to vote against
the Plan, against an adjournment. Approval  of the Plan will be deemed  approval
of the amendment to the articles of incorporation of the Company attached to the
Plan.
 
EXPENSES OF SOLICITATION
 
    All  expenses  of this  solicitation, including  the  cost of  preparing and
mailing this  Proxy  Statement/  Prospectus,  will be  borne  by  Piper  Capital
Management Incorporated ("Piper Capital"), investment manager to the Company and
Piper Global. In addition to the solicitation of proxies by mail, proxies may be
solicited by officers and regular employees of the Company, Piper Capital or the
Fund's  distributor,  without  compensation  other  than  regular  compensation,
personally or  by mail,  telephone, telegraph  or otherwise.  Brokerage  houses,
banks  and other fiduciaries may be  requested to forward soliciting material to
the beneficial owners of shares and to obtain authorization for the execution of
proxies. For those services,  if any, they will  be reimbursed by Piper  Capital
for their reasonable out-of-pocket expenses. In addition, arrangements have been
made  with  Shareholder Communications  Corporation, an  independent shareholder
communication firm, to assist in the solicitation of proxies.
 
VOTE REQUIRED
 
    Approval of the  Plan by  the Fund's shareholders  requires the  affirmative
vote  of a majority (I.E., more than 50%) of the outstanding shares of the Fund.
If the Plan is not approved by shareholders, the Fund will continue in existence
and the Board will consider alternative actions.

                                    SYNOPSIS
 
    THE FOLLOWING IS A SYNOPSIS OF CERTAIN INFORMATION CONTAINED OR INCORPORATED
BY REFERENCE IN THIS PROXY STATEMENT/PROSPECTUS. THIS SYNOPSIS IS ONLY A SUMMARY
AND IS QUALIFIED IN ITS ENTIRETY  BY THE MORE DETAILED INFORMATION CONTAINED  OR
INCORPORATED  BY  REFERENCE IN  THIS  PROXY STATEMENT/PROSPECTUS  AND  THE PLAN.
SHAREHOLDERS SHOULD  CAREFULLY REVIEW  THIS PROXY  STATEMENT/PROSPECTUS AND  THE
PLAN   IN  THEIR  ENTIRETY  AND,  IN   PARTICULAR,  THE  CURRENT  PROSPECTUS  OF
PACIFIC-EUROPEAN FUND WHICH IS ATTACHED  TO THIS PROXY STATEMENT/PROSPECTUS  AND
WHICH IS INCORPORATED HEREIN BY REFERENCE.
 
THE REORGANIZATION
 
    The Plan provides for the transfer of substantially all of the assets of the
Fund,  subject to stated  liabilities, to Pacific-European  Fund in exchange for
Pacific-European Fund Shares. The aggregate net asset value of  Pacific-European
Fund  Shares issued in  the exchange will  equal the aggregate  value of the net
assets of the Fund  received by Pacific-European Fund.  On or after the  closing
date  scheduled  for  the Reorganization  (the  "Closing Date"),  the  Fund will
distribute Pacific-European  Fund Shares  received  by the  Fund to  holders  of
shares  of  the  Fund  issued  and outstanding  as  of  the  Valuation  Date (as
hereinafter defined) in complete liquidation of the Fund. If all other series of
the Company effect similar reorganizations  or otherwise liquidate, the  Company
will  take  all  necessary  steps  to  effect  its  dissolution  as  a Minnesota
corporation and its deregistration under the Investment Company Act of 1940,  as
amended  (the  "1940  Act").  As  a  result  of  the  Reorganization,  each Fund
shareholder will receive  that number  of full  and fractional  Pacific-European
Fund  Shares equal in value to such  shareholder's shares of the Fund. A similar
reorganization is being proposed to shareholders of Hercules Pacific Basin Value
Fund.  If  shareholders   of  that  fund   approve  a  similar   reorganization,
substantially  all of  the assets of  that fund, subject  to stated liabilities,
will also be transferred to Pacific-European Fund. The Board has determined that
the interests of existing Fund shareholders will  not be diluted as a result  of
the Reorganization.
 
    FOR  THE REASONS  SET FORTH BELOW  UNDER "THE REORGANIZATION  -- THE BOARD'S
CONSIDERATION,"  THE  BOARD,  INCLUDING  ALL  OF  THE  DIRECTORS  WHO  ARE   NOT
"INTERESTED  PERSONS" OF THE  COMPANY, AS THAT  TERM IS DEFINED  IN THE 1940 ACT
("INDEPENDENT DIRECTORS"), HAS UNANIMOUSLY CONCLUDED THAT THE REORGANIZATION  IS
IN  THE BEST INTERESTS OF THE FUND  AND ITS SHAREHOLDERS AND RECOMMENDS APPROVAL
OF THE PLAN.

FEE TABLE
 
    The funds each  pay a variety  of expenses for  management of their  assets,
distribution  of  their  shares  and  other  services,  and  those  expenses are
reflected  in  the  net  asset  value  per  share  of  each  of  the  Fund   and
Pacific-European Fund. The following table sets forth the expenses and fees that
shareholders  of the Fund  and Pacific-European Fund  incurred during the twelve
months ended February 29, 1996. The Pro Forma Combined fees reflect what the fee
schedule would have  been at February  29, 1996, if  the Reorganization and  the
proposed   reorganization   of   Hercules   Pacific   Basin   Value   Fund  into
Pacific-European Fund (discussed  above) had  occurred 12 months  prior to  that
date.  If the proposed reorganization of  Hercules Pacific Basin Value Fund into
Pacific-European Fund does not  occur, the expenses set  forth in the Pro  Forma
Combined column would not be materially different from those presented below.

</TABLE>
 
- ------------------------
 
(1) No sales charge will be imposed on Shares acquired in the Reorganization. On
    unrelated  purchases,  the  front  end  sales  charge  of  4.00%  applies to
    purchases less than $100,000 and scales down to 0% on purchases of  $500,000
    or more.
 
(2) The  maximum 2.00%  contingent deferred sales  charge on shares  of the Fund
    applies to redemptions during the first 365 days after purchase; the  charge
    declines  to 1.00%  during the next  365 days after  purchase, reaching zero
    thereafter. No CDSC is imposed on  shares purchased prior to June 19,  1995.
    In  connection with purchases of Pacific-European  Fund of $500,000 or more,
    on which no front-end sales charge is imposed, a 1.00% CDSC will be  imposed
    on  redemptions occurring within  24 months of  purchase. See "Comparison of
    the Fund and Pacific-European Fund -- Purchases, Redemptions and Exchanges."
 
(3) There is a $50 fee for each exchange in excess of 12 exchanges per year  for
    the  Fund. There is a $5 fee for  each exchange in excess of 4 exchanges per
    year for Pacific-European Fund.
 
(4) With respect to Pacific-European Fund and  the Pro Forma Combined fund,  the
    Management Fees may be more or less than those set forth in the table to the
    extent   that  Pacific-European  Fund  and   the  Pro  Forma  Combined  fund
    outperforms or underperforms  the EAFE  Index (as defined  herein). For  the
    fiscal year ended February 29, 1996, the performance fee adjustment resulted
    in  a reduction  of Management  Fees of 0.21%  of average  daily net assets.
    Absent such reduction, Management Fees for Pacific-European Fund and the Pro
    Forma Combined fund would  be 0.95% and 0.93%  of average daily net  assets,
    respectively.  See  "Comparison of  the  Fund and  Pacific-European  Fund --
    Investment Management and Distribution Plan Fees."
 
(5) 12b-1 fees  for the  Fund and  Pacific-European Fund  are currently  limited
    voluntarily   by   the   Fund's  distributor,   Piper   Jaffray   Inc.  (the
    "Distributor"). Absent  such fee  limitation, the  Rule 12b-1  fees may  not
    exceed  0.70% and 0.50%  per annum of  the average daily  net assets for the
    Fund and Pacific-European  Fund, respectively.  A portion of  the 12b-1  fee
    equal to 0.25% of average daily net assets is characterized as a service fee
    within  the meaning of the National  Association of Securities Dealers, Inc.
    ("NASD") guidelines.
 
                                       4
<PAGE>
(6) Piper Capital has voluntarily limited  Total Fund Operating Expenses of  the
    Fund on a per annum basis to 2.00% of average daily net assets. As a result,
    certain  Other Expenses  are currently borne  by Piper  Capital. Absent such
    limitations, for the 12 months ended February 29, 1996, Other Expenses would
    have been 1.96% of the average daily  net assets for the Fund. Without  such
    limitations  and  the  12b-1  fee limitations  discussed  above,  Total Fund
    Operating Expenses  for  the  12  months  ended  February  29,  1996,  as  a
    percentage  of average  daily net assets,  would have been  3.66%, 1.73% and
    1.70% for the Fund, Pacific-European Fund and the Pro Forma Combined column,
    respectively.  Pacific-European  Fund's  limitations   may  be  revised   or
    terminated  at any  time subsequent  to the  end of  its fiscal  year. Piper
    Capital and the Fund's distributor do  not presently intend to continue  any
    limitations for the Fund beyond the Fund's fiscal year ending June 30, 1996.
 
    EXAMPLE
 
    To  attempt to show the effect of these expenses on an investment over time,
the example shown below has been created. The expenses set forth in the  example
below  may increase if the fee  limitations and expense reimbursements discussed
above are removed. As noted above, Pacific-European Fund charges a maximum 4.00%
front-end sales charge  on new  purchases. The  expenses shown  below have  been
calculated  as if no such sales charge was imposed because Fund shareholders who
receive Pacific-European  Fund Shares  in the  Reorganization will  not pay  the
front-end  sales charge with respect to  those shares. Assuming that an investor
makes a $1,000 investment in  either the Fund or  Pacific-European Fund or on  a
Pro  Forma Combined basis,  that the annual  return is 5.00%  and that the Total
Fund Operating Expenses for each fund are the ones shown in the chart above,  if
the  investment was redeemed at the end of each period shown below, the investor
would incur the following expenses by the end of each period shown:

 *Expenses  for shares of Pacific-European Fund purchased subject to the maximum
  front end sales  charge are: $55,  $87, $121  and $217 for  the one-,  three-,
  five- and ten-year periods shown, respectively.
**Expenses  for shares  of Pacific-European Fund  on a Pro  Forma Combined basis

    Long-term shareholders of  either fund  may pay  more in  sales charges  and
distribution  fees than the  economic equivalent of  the maximum front-end sales
charges permitted by the NASD.
 
TAX CONSEQUENCES OF THE REORGANIZATION
 
    As a condition to  the Reorganization, the Fund  will receive an opinion  of
the law firm Gordon Altman Butowsky Weitzen Shalov & Wein to the effect that the
Reorganization  will constitute a tax-free reorganization for Federal income tax
purposes, and  that no  gain or  loss  will be  recognized by  the Fund  or  the
shareholders  of the  Fund for Federal  income tax  purposes as a  result of the
Reorganization. For  further  information  about the  tax  consequences  of  the
Reorganization,  see "The Reorganization  -- Tax Aspects  of the Reorganization"
below.

DISSENTING SHAREHOLDERS' RIGHTS OF APPRAISAL
 
    Although under  Minnesota  law  shareholders  of a  company  acquired  in  a
reorganization  who do  not vote  to approve  the reorganization  generally have
"appraisal rights"  (where they  may elect  to have  the "fair  value" of  their
shares  (determined in accordance  with Minnesota law)  judicially appraised and
paid to them), the Division of Investment Management of the Commission has taken
the position that Rule 22c-1 under the 1940 Act preempts appraisal provisions in
state statutes.  This rule  provides  that no  open-end investment  company  may
redeem its shares other than at net asset value next computed after receipt of a
tender  of such security for redemption. For further information about rights of
appraisal, see "The Reorganization -- Dissenters' Rights."
 
COMPARISON OF THE FUND AND PACIFIC-EUROPEAN FUND
 
    INVESTMENT OBJECTIVES AND POLICIES.  The Fund and Pacific-European Fund have
similar investment  objectives.  The  Fund's objectives  are  long-term  capital
appreciation  and, to a lesser extent,  current income. The investment objective
of Pacific-European Fund  is long-term capital  appreciation. Current income  is
incidental   to  this  objective.  The  investment  objective  of  the  Fund  is
fundamental and may not be changed without shareholder approval. The  investment
objective  of Pacific-European Fund is  non-fundamental and, accordingly, it may
be changed without shareholder approval.
 
    The Fund  seeks to  achieve  its investment  objective by  investing,  under
normal  circumstances, at least 65% of its  total assets in securities issued by
issuers in Europe (including up to 10% in Eastern Europe). Pacific-European Fund
seeks  to  achieve   its  investment  objective   by  investing,  under   normal
circumstances,  at least  65% of  its total assets  in Common  Stock (as defined
herein) of  companies in  the  Pacific Basin  or  in Europe  (including  Eastern
Europe).  Up to 25% of  Pacific-European Fund's total assets  may be invested in
other areas of the world to  the extent significant opportunities for  long-term
capital  appreciation outside of the Pacific  Basin and Europe become available.
Accordingly,  the  principal   difference  between   the  two   funds  is   that
Pacific-European  Fund invests primarily in  countries that comprise the Pacific
Basin and Europe and may invest  up to 25% of its  assets in other areas of  the
world,  whereas  the Fund  invests primarily  in  Europe. In  addition, although
emphasis is placed  on investments  in equity  securities, the  Fund may  invest
without  limitation  in investment  grade  debt securities  of  governmental and
private   issuers   (including   bonds,   notes,   debentures,   Brady    Bonds,
mortgage-backed securities and asset-backed securities), whereas
Pacific-European Fund invests in debt instruments solely for temporary defensive
purposes.
 
    The  Fund  and  Pacific-European  Fund  may  invest  in  American Depository
Receipts ("ADRs"), European Depository Receipts ("EDRs") and in other investment
companies (up to  the limits  prescribed by  the 1940  Act). The  Fund may  also
invest  up to 10% of its total assets in foreign index linked instruments and in
loan participations and  assignments; Pacific-European Fund  does not invest  in
these types of securities.
 
    The  Fund may purchase and sell put  and call options, futures contracts and
options on futures contracts  with respect to  financial instruments, stock  and
interest rate indexes and foreign currencies. Futures and options may be used to
facilitate  allocation of the Fund's investment among asset classes, to generate
income or to hedge against declines in securities prices or increases in  prices
of  securities proposed to be purchased.  Pacific-European Fund may, for hedging
purposes only, buy or sell  put and call options on  the securities in which  it
may  invest and  enter into futures  contracts and options  on futures contracts
based on financial indices including any  index of securities in which the  Fund
may  invest. Both funds may  buy or sell options,  futures or options on futures
that are traded on U.S. or  foreign exchanges or over-the-counter. In  addition,
both  funds  may enter  into currency  exchange transactions  (including forward
foreign currency exchange contracts and futures and options contracts on foreign
currencies), as a hedge against fluctuations in foreign exchange rates.
 
    Both the  Fund  and  Pacific-European  Fund may  purchase  securities  on  a
when-issued  or delayed delivery basis and may  purchase or sell securities on a
forward commitment basis. Both funds may invest in warrants up to 5% of its  net
assets.  Both  funds may  enter into  repurchase  agreements subject  to certain
procedures designed to minimize risks associated with such agreements.  Although
both
 
                                       6
<PAGE>
funds  may enter into reverse repurchase  agreements, neither fund has, nor does
Pacific-European  Fund  have  any  current  intention  of  entering  into   such
agreements  in the future.  The Fund may  invest in zero  coupon bonds, deferred
interest bonds and bonds on which the interest is payable in kind ("PIK Bonds");
Pacific-European Fund does not invest in these instruments.
 
    In addition, the Fund  is a non-diversified  investment company, within  the
meaning  of  the  1940  Act,  whereas  Pacific-European  Fund  is  a diversified
investment company.
 
    For a more detailed comparison of the investment objectives and policies  of
the  Fund and Pacific-European  Fund, see "Comparison  of Investment Objectives,
Policies and Restrictions," below.
 
    INVESTMENT  MANAGEMENT   AND   DISTRIBUTION   PLAN  FEES.   The   Fund   and
Pacific-European  Fund have the  same Board of Directors.  In addition, the Fund
and Pacific-European Fund  obtain management  services from  Piper Capital.  For
each fund, fees are payable monthly based on the average net asset value of such
fund  as of the close of business each day. The Fund pays a management fee at an
annual rate of 1.00% of its average net asset value. Pacific-European Fund  pays
a  management fee at an annual rate of  1.00% of the portion of daily net assets
up to $100 million, 0.875% of such assets between $100 million and $200  million
and  0.75% of the portion of daily net assets exceeding $200 million (the "Basic
Fee"), and is subject to adjustment as described below. The adjustment is  based
upon  the investment  performance of  Pacific-European Fund  in relation  to the
investment  record  of  the  Morgan  Stanley  Capital  International   European,
Australian and Far East Index (the "EAFE-SM- Index"). The EAFE Index is a market
capitalization  weighted  index  containing  (as  of  February  29,  1996) 1,109
companies representing approximately 60% of the market capitalization of each of
the following 20 countries or territories: Australia, Austria, Belgium, Denmark,
Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, The Netherlands, New
Zealand, Norway, Singapore, Malaysia, Spain, Sweden, Switzerland and the  United
Kingdom.  The Basic Fee  for each month may  be increased or  decreased by up to
0.25% (on  an annualized  basis) of  Pacific-European Fund's  average daily  net
assets  depending upon the  extent by which  Pacific-European Fund's performance
varies from the EAFE  Index over the applicable  performance period. For a  more
detailed  discussion  of  the  performance component  of  the  advisory  fee for
Pacific-European   Fund,   see   "Management    --   Investment   Adviser"    in
Pacific-European Fund's current Prospectus.
 
    With  respect to the Fund, Piper Capital has retained the services of Pictet
International Limited  ("Pictet") as  sub-adviser to  manage the  portfolio.  As
compensation  for its services  Piper Capital pays  Pictet monthly compensation,
calculated in the same manner  as the investment advisory  fee, of 0.50% of  net
assets  of the  Fund. With respect  to Pacific-European Fund,  Piper Capital has
retained the services of Edinburgh Fund  Managers plc ("EFM") as sub-adviser  to
manage  the portfolio. As compensation for  its services, Piper Capital pays EFM
monthly compensation, calculated in the  same manner as the investment  advisory
fee, of 65% of the Basic Fee plus or minus 90% of the performance fee adjustment
described  above. EFM has  entered into an  expense reimbursement agreement with
Piper Capital under which it  pays Piper Capital a monthly  fee equal to 10%  of
the  Basic Fee.  This 10% fee  is a  reimbursement to Piper  Capital for certain
expenses it  bears in  connection with  the administration  of  Pacific-European
Fund.
 
    Both  the  Fund and  Pacific-European Fund  have adopted  distribution plans
(each, a "12b-1 Plan") pursuant  to Rule 12b-1 under  the 1940 Act. Pursuant  to
the  Fund's 12b-1 Plan,  the Distributor is  compensated on a  monthly basis for
shareholder account servicing and distribution-related services. This fee is not
tied exclusively to expenses actually incurred by the Distributor and may exceed
such expenses. Payments under Pacific-European Fund's 12b-1 Plan are made to the
Distributor each  month to  reimburse the  Distributor for  its actual  expenses
incurred  in connection  with servicing  of Pacific-European  Fund's shareholder
accounts and  in connection  with  distribution-related services  provided  with
respect to Pacific-European Fund's 12b-1 Plan. Payments under the 12b-1 Plan may
not  exceed 0.70% of average daily net assets  in the case of the Fund and 0.50%
in the case of  Pacific-European Fund. The  Distributor has voluntarily  limited
reimbursements  under each 12b-1 Plan to 0.50% in the case of the Fund and 0.32%
in  the   case   of   Pacific-European   Fund.   In   the   case   of   Pacific-
 
                                       7
<PAGE>
European  Fund, this limitation may  be revised or terminated  at any time after
its fiscal year end. In the case of the Fund, Piper Capital and the  Distributor
do  not presently intend to continue these limitations beyond the Fund's current
fiscal year.
 
    OTHER SIGNIFICANT  FEES.    Both  the Fund  and  Pacific-European  Fund  pay
additional  fees in connection with their operations, including legal, auditing,
transfer agent and custodial fees. See  "Fee Table" above for the percentage  of
average net assets represented by such Other Expenses.
 
    PURCHASES, REDEMPTIONS AND EXCHANGES.
 
    PURCHASES.  The Fund and Pacific-European Fund each continuously issue their
shares  to investors at  a price equal  to net asset  value at the  time of such
issuance. Investors  in Pacific-European  Fund, however,  also pay  a  front-end
sales  charge of 4.00% on  purchases of less than $100,000  scaled down to 0% on
purchases of $500,000 and above. Shareholders  of the Fund who acquire  Pacific-
European  Fund Shares  in the  Reorganization will  not pay  the front-end sales
charge on such Shares; however, such sales charge will be applied to  additional
purchases of Pacific-European Fund. Shares of the Fund and Pacific-European Fund
are  distributed by  the Distributor and  other broker-dealers  who have entered
into selected broker-dealer agreements with the Distributor. Purchase orders for
shares of the  Fund will not  be accepted after  the date on  which the Plan  is
approved by Fund shareholders.
 
    REDEMPTIONS.   Shareholders of the Fund and Pacific-European Fund may redeem
their shares  for cash  at  any time  at  the net  asset  value per  share  next
determined;  however, such redemption proceeds will  be reduced by the amount of
any applicable contingent deferred sales charge ("CDSC"). In most circumstances,
redemptions of Fund shares made  within two years of  purchase are subject to  a
CDSC,  scaled down from 2.00%  to 1.00% of the amount  redeemed. No CDSC will be
applied to  shares  of  the  Fund  at the  time  of  the  Reorganization  or  to
Pacific-European  Fund Shares  acquired in  the Reorganization  on redemption of
such Shares. With  respect to Pacific-European  Fund, shareholders who  invested
more than $500,000 and, accordingly, paid no front-end sales charge, are in most
circumstances  subject to a  CDSC if shares  are redeemed within  24 months. The
charge is equal to 1.00% of the lesser  of the net asset value of the shares  at
the  time of purchase or at the time of redemption. Pacific-European Fund offers
a reinstatement privilege whereby a shareholder whose shares have been  redeemed
may,  within thirty days after the date  of redemption invest any portion or all
of the proceeds  thereof in another  fund managed by  Piper Capital (other  than
portfolios  of the Company) without payment of an additional sales charge, or if
such redemption was subject to  a CDSC, pro rata credit  will be given for  such
CDSC.  The Fund and Pacific-European Fund may redeem involuntarily, at net asset
value, accounts valued at less than $200.
 
    EXCHANGES.  Each of  the Fund and Pacific-European  Fund makes available  to
its  shareholders exchange privileges allowing exchange  of shares for shares of
certain other funds. Shares of  the Fund may be exchanged  for shares of any  of
the  five  other series  of  the Company.  Pacific-European  Fund Shares  may be
exchanged for shares of any of the 15 other funds open to new investors that are
advised by  Piper  Capital. Both  the  Fund and  Pacific-European  Fund  provide
telephone exchange privileges to their shareholders.
 
    For  a  more detailed  discussion  of purchasing,  redeeming  and exchanging
Pacific-European Fund  shares, see  "Shareholder Guide  to Investing  -- How  to
Purchase  Shares," "--  How to Redeem  Shares" and "--  Shareholder Services" in
Pacific-European Fund's current Prospectus.
 
    DIVIDENDS.   Dividends  from both  the  Fund's and  Pacific-European  Fund's
anticipated  net  investment  income  are declared  and  paid  annually  and net
short-term capital gains and long-term  capital gains distributions are paid  at
least  once annually. Dividends and capital gains distributions of both the Fund
and Pacific-European Fund are automatically  reinvested in additional shares  at
net asset value unless the shareholder elects to receive cash.

                             PRINCIPAL RISK FACTORS
 
    The  Fund and Pacific-European Fund  each pursue their respective investment
objectives through investment in foreign securities. Accordingly, they are  both
subject to the same general risks associated with international investing. These
risks  include:  risks  relating  to  adverse  currency  fluctuations, potential
political and economic instability of  certain countries, limited liquidity  and
greater  volatility of  prices as  compared to  U.S. securities,  investment and
repatriation restrictions,  and  foreign taxation.  Their  risks differ  to  the
extent  that Pacific-European Fund invests in  both the Pacific Basin and Europe
and may invest up to 25% of its  assets anywhere in the world, whereas the  Fund
invests  primarily  in  Europe.  Many  of the  countries  and  markets  in which
Pacific-European Fund is authorized to invest  are less developed than those  of
Europe.  Accordingly, the Pacific-European Fund  may invest a greater percentage
of its assets  in less developed  and emerging market  countries than the  Fund.
Investments  in such  less developed  and emerging  markets generally  involve a
greater degree of risk than do investments in more developed markets.
 
    Another  difference  between  the  two  funds  is  that  although  the  Fund
emphasizes  investment in  equity securities, it  may also  pursue its objective
through investment in investment  grade debt securities  and may invest  without
limitation  in such securities. By contrast, Pacific-European Fund may invest in
debt securities  solely for  defensive purposes.  Accordingly, the  Fund may  be
subject  to  the risks  associated with  investments  in debt  securities (E.G.,
credit risk, interest rate risk) to a greater extent than Pacific-European Fund.
 
    While both Funds  may participate  in the  futures and  options markets  for
hedging  purposes, and the risks of such participation are similar, the Fund may
also enter into such transactions  for speculative purposes to generate  income.
In  addition, as  discussed above,  the Fund  may invest  in zero  coupon bonds,
deferred interest bonds and PIK Bonds and Pacific-European Fund does not  engage
in  such transactions. Accordingly, Pacific-European Fund  is not subject to the
risks associated with these transactions.
 
    In addition, as discussed  above, the Fund  is a non-diversified  investment
company  under  the 1940  Act, whereas  Pacific-European  Fund is  a diversified
investment company. As a result, the Fund may invest a higher percentage of  its
assets in a more limited number of issuers than Pacific-European Fund.
 
    The  foregoing discussion is a summary of  the principal risk factors. For a
more  complete  discussion  of  the  risks  of  each  fund,  see  "Special  Risk
Considerations"  in the Fund's Prospectus and "Risk Factors" in Pacific-European
Fund's Prospectus.
 
                               THE REORGANIZATION
 
BACKGROUND
 
    The Company  was  initially managed  through  a joint  venture  ("Hercules")
between  Piper  Jaffray Companies,  Inc.  ("Piper Jaffray")  and  Midland Walwyn
Capital Corporation ("Midland") pursuant to which the parties agreed to  jointly
promote,  distribute and  manage a family  of international funds  in the United
States and Canada. The Company's shares were first offered to the public in  the
U.S. on November 9, 1993.
 
    The  Company's shares, including shares of the Fund, were originally offered
for sale with no front-end or back-end  sales charge. In lieu of a sales  charge
paid  by investors, Hercules and each sub-adviser retained by Hercules to manage
the portfolio of each series of the Company, advanced to broker-dealers a  sales
commission  (except with respect to  the Money Market Fund)  in the aggregate of
2.00% of the net asset value of  shares purchased. If a shareholder redeemed  in
less  than two years,  all or a  portion of the  advanced commission was charged
back to the broker-dealer.  If a shareholder exchanged  among the series  within
the  same two year period, the sub-advisers paid,  or were paid, as the case may
be, a portion of the commission advance  that had not yet been recovered.  While
initially  the Company, including the Fund, experienced positive growth, a trend
of net redemptions commenced in November of 1994 which has yet to be reversed.
 
                                       9
<PAGE>
    In April 1995, Piper Jaffray and Midland announced their mutual agreement to
terminate  the  joint  venture  arrangement  and  to  dissolve  Hercules.  After
requisite shareholder approval was obtained in July 1995, Piper Capital  assumed
the role of manager and investment adviser for the Company.
 
    After  becoming  manager  to  the  Company,  Piper  Capital  focused  on the
structure, pricing and  marketing of the  various Hercules funds  in the  United
States  in an attempt to promote asset growth in the funds and reverse the trend
of net redemptions. In particular,  it invested considerable time and  financial
resources  to develop a distribution network  with broker-dealers in addition to
Piper Jaffray because Piper Capital believed that the development of an external
distribution system was critical to the successful distribution of the  Hercules
funds.
 
    As part of this effort, a change in the pricing structure was implemented in
June  1995  incorporating a  CDSC. Implementation  of the  CDSC was  intended to
eliminate the need to recoup from the broker-dealer through whom the shares were
sold the  commissions  advanced  to  it by  Piper  Capital  and  the  applicable
sub-adviser  in the event of a redemption  within two years of purchase. In lieu
thereof, shareholders would be required to  pay a declining CDSC if shares  were
redeemed  within  two  years of  purchase.  It  was believed  that  this pricing
structure would  prove  attractive  to  broker-dealers  as  well  as  to  future
investors.  The implementation  of the CDSC  did not, however,  have the desired
effect on growth. Rather, the trend of net redemptions continued. Latin American
Value Fund and Money Market Fund are the only Hercules funds which have had even
one month since October 1994  where shareholder purchases exceeded  redemptions.
Moreover,  sales  through  broker-dealers  other  than  Piper  Jaffray  remained
minimal.
 
    The continuing  inability to  achieve  asset growth  in the  Hercules  funds
prompted a further review by Piper Capital of the future prospects of the funds.
Ultimately,  Piper Capital concluded that it is unlikely that the Hercules funds
will, in the  foreseeable future grow  to a sufficient  size to be  economically
viable.  Accordingly, Piper Capital recommended to the Board of Directors of the
Company that the Hercules funds be eliminated as a free standing family of funds
and that instead each Hercules fund be combined with an appropriate fund  within
the  Piper family of funds (or, in the  case of World Bond Fund and Money Market
Fund, that the fund be liquidated).
 
THE BOARD'S CONSIDERATION
 
    At a meeting  of the  Board of  Directors held  on February  6, 1996,  Piper
Capital reviewed for the Board the basis for its recommendation. It detailed the
efforts that have been made since inception of the Hercules Funds to promote and
market  the  funds,  the  continuing  inability  to  reverse  the  trend  of net
redemptions that has continued  since November 1994  despite these efforts,  and
the basis for its pessimistic view respecting the Company's future prospects.
 
    At  its  meeting  on February  6,  1996,  the Board,  including  all  of the
Independent Directors, unanimously approved the Reorganization and on March  29,
1996 approved the Plan and determined to recommend that shareholders of the Fund
approve the Plan.
 
    In  determining whether to  recommend that shareholders  of the Fund approve
the Plan,  the  Board, with  the  advice  and assistance  of  independent  legal
counsel,  inquired into a number of matters. In particular, the Board considered
the Company's  prospects for  future  growth and  the effect  upon  shareholders
should  assets remain at current  levels or continue to  be reduced further. The
Board considered in this regard that since the commencement of operations, Piper
Capital (or Hercules) has voluntarily limited total expenses of the Fund and the
Distributor has voluntarily limited its 12b-1 fees payable by the Fund but  they
do  not presently intend to continue  these limitations beyond the Fund's fiscal
year ending  June 30,  1996. The  Board  noted that  absent such  assumption  of
expenses  and waiver of fees, the expense ratio of the Fund for the most current
fiscal year would have been considerably higher and total return lower.
 
    The  Board  carefully  considered   the  compatibility  of  the   investment
objectives,   policies,   restrictions   and   portfolios   of   the   Fund  and
Pacific-European Fund. In particular,  the Board focused  on the differences  in
the  investment  policies  of  the  Fund  and  Pacific-European  Fund.  The most
significant
 
                                       10
<PAGE>
difference between the  two, as  discussed more  fully below  in "Comparison  of
Investment  Objectives, Policies  and Restrictions --  Investment Objectives and
Policies," is that the Fund invests primarily in Europe (including up to 10%  in
Eastern  Europe) whereas Pacific-European Fund  invests primarily in the Pacific
Basin  as  well  as  Europe  (including  Eastern  Europe).  In  considering  the
suitability  of  Pacific-European  Fund  for  shareholders  of  the  Fund  given
Pacific-European  Fund's   broader  geographic   focus,  the   Board   evaluated
information  provided  by  Piper  Capital  that  indicated  that  a  significant
percentage of shareholders of  the Fund were also  shareholders of the  Hercules
Pacific  Basin  Fund and  therefore were  investors who  sought exposure  to the
Pacific Basin and Europe.
 
    The Board also  considered the  fact that the  sub-adviser for  the Fund  is
Pictet  whereas EFM is  the sub-adviser for  Pacific-European Fund. Accordingly,
the Reorganization would, from the standpoint of Fund shareholders, result in  a
change of sub-advisers. The Board evaluated the nature, scope and quality of the
investment  advisory  services provided  by EFM  relative  to those  provided by
Pictet and  concluded  that  the  change  would be  in  the  best  interests  of
shareholders of the Fund.
 
    In  addition,  the  Board  considered  the  comparative  expenses  currently
incurred in the operation of the  Fund and Pacific-European Fund, the terms  and
conditions  of the proposed  Reorganization, the comparative  performance of the
funds, PCM's undertaking to pay all  direct costs (E.G., proxy solicitation)  of
the  Reorganization,  and  the indirect  costs  (E.G., brokerage)  likely  to be
incurred by the Fund in  the Reorganization. In recommending the  Reorganization
to  the shareholders of  the Fund, the Board  considered that the Reorganization
would have the following benefits for shareholders of the Fund:
 
        1.  The total expenses borne by shareholders of the combined fund should
    be lower on  a percentage basis  than the  total expenses per  share of  the
    Fund.  The Fund's expense ratio for its  fiscal year ended June 30, 1995 was
    2.00%, giving  effect  to waivers  and  expense reimbursements  which  Piper
    Capital  and the Distributor  intend to discontinue  after the Fund's fiscal
    year ending June 30, 1996. Absent such waivers and reimbursements,  expenses
    would  have been 3.21%. By contrast,  the expense ratio for Pacific-European
    Fund for its fiscal year ended February 28, 1995 was 1.76%, giving effect to
    the Distributor's  voluntary  limitation. Absent  such  limitation  expenses
    would  have been 1.98%. The Distributor  has voluntarily agreed to limit the
    12b-1 fee to  an annual  rate of  0.32% of  Pacific-European Fund's  average
    daily   net  assets  for  its  current   fiscal  year.  (Advisory  fees  for
    Pacific-European Fund  could, in  the  future, be  more  or less  than  that
    incurred  during  its last  fiscal  year because  the  fee is  subject  to a
    performance based  adjustment upward  or downward  of 0.25%.)  In  addition,
    Pacific-European  Fund's advisory fee  scales down as  asset levels increase
    and, because Pacific-European Fund  is much larger than  the Fund, there  is
    the  opportunity  to benefit  from  economies of  scale,  greater investment
    diversification  and  facilitation   of  portfolio   management.  In   fact,
    subsequent  to  the  Reorganization  (and  the  proposed  reorganization  of
    Hercules Pacific Basin Value Fund  into Pacific-European Fund, as  discussed
    above)  advisory  fees  for  Pacific-European  Fund  may  be  reduced,  as a
    percentage of net assets, due to increased net assets of the combined funds.
 
        2.   Shareholders  of  the  Fund  will be  able  to  acquire  shares  of
    Pacific-European  Fund,  which  are  otherwise subject  to  a  maximum 4.00%
    front-end sales charge, at net asset  value and pursue a similar  investment
    objective  in a larger  and more economically viable  fund without having to
    sell their shares. Moreover, shareholders will be able to redeem the  shares
    so  acquired at net asset value without  any CDSC being imposed and will not
    pay any CDSC on Fund shares converted in the Reorganization.
 
        3.  The Fund's shareholders would retain the capabilities and  resources
    of  Piper Capital and its affiliates in the areas of operations, management,
    distribution, shareholder servicing and marketing.
 
        4.  The Reorganization would enable the Fund's shareholders to enjoy  an
    expanded  range of mutual fund investment  options. The Piper Funds complex,
    of which Pacific-European  Fund is  a part,  includes 15  other mutual  fund
    portfolios  that will  be available  for exchange  by Fund  shareholders who
    receive Pacific-European Fund Shares in the Reorganization.
 
                                       11
<PAGE>
        5.  The  Reorganization will  constitute a  tax-free reorganization  for
    Federal  income tax purposes, and no gain  or loss will be recognized by the
    Fund or its shareholders for Federal income tax purposes as a result of  the
    Reorganization.
 
    Based  on the foregoing, the Board  determined that the Reorganization is in
the best interests of the shareholders of the Fund and that the interests of the
Fund shareholders will not be diluted as a result thereof.
 
    The Board  of  Directors of  Pacific-European  Fund, including  all  of  the
Independent  Directors, has  also determined that  the Reorganization  is in the
best interests  of Pacific-European  Fund  and that  the interests  of  existing
shareholders  of Pacific-European Fund will not  be diluted as a result thereof.
The  transaction  will  enable  Pacific-European  Fund  to  acquire   investment
securities  which are consistent with its objectives without the brokerage costs
attendant to the purchase of such  securities in the market. Also, the  addition
of the Fund's assets should result in some cost savings to the extent that fixed
expenses  can be spread over a larger asset base. A larger asset base could also
lead to reduced management fees as  a result of "breakpoints" in the  management
fees payable by Pacific-European Fund.
 
THE PLAN
 
    The terms and conditions under which the Reorganization would be consummated
are set forth in the Plan and are summarized below. This summary is qualified in
its  entirety by reference to the Plan, a copy of which is attached as EXHIBIT A
to this Proxy Statement/Prospectus.
 
    The Plan  provides  that (i)  the  Fund will  transfer  all of  its  assets,
including  appropriate portfolio securities, cash, cash equivalents, securities,
commodities, futures and dividend  and interest receivables to  Pacific-European
Fund on the Closing Date in exchange for the assumption by Pacific-European Fund
of  the Fund's  stated liabilities, including  all expenses,  costs, charges and
reserves, as reflected on  an unaudited statement of  assets and liabilities  of
the  Fund prepared by the  Treasurer of the Company as  of the Valuation Date in
accordance with generally  accepted accounting  principles consistently  applied
from the prior audited period, and the delivery of Pacific-European Fund Shares;
(ii)  such Pacific-European Fund Shares will  be distributed to the shareholders
of the Fund on the Closing Date or as soon as practicable thereafter; and  (iii)
the Company shall be dissolved as a Minnesota corporation and deregistered as an
investment  company under  the 1940  Act, promptly  following the  making of all
distributions and the reorganization or liquidation of each other series of  the
Company.  In most  cases, reorganization or  liquidation of the  other series is
contingent on obtaining the approval of shareholders of the series.
 
    For technical reasons, certain of the Fund's existing investment limitations
may be deemed to preclude the  Fund from consummating the Reorganization to  the
extent  that the Reorganization would involve the Fund holding all of its assets
as shares of  Pacific-European Fund  until such  shares are  distributed to  the
Fund's  shareholders. By  approving the  Plan, the  Fund's shareholders  will be
deemed to have agreed to waive each of these limitations.
 
    The number of Pacific-European Fund Shares to be delivered to the Fund  will
be   determined  by  dividing   the  value  of  the   Fund  assets  acquired  by
Pacific-European Fund  (net of  stated liabilities  assumed by  Pacific-European
Fund) by the net asset value of a Pacific-European Fund Share; these values will
be  calculated as of the close  of business of the New  York Stock Exchange on a
business day not later than the fifth business day following the receipt of  the
requisite  approval by the shareholders of the Fund of the Plan or at such other
time as the Fund and Pacific-European Fund may agree (the "Valuation Date"). The
net asset value of a  Pacific-European Fund Share shall  be the net asset  value
per  share computed  on the Valuation  Date, using the  valuation procedures set
forth in  Pacific-European  Fund's  then current  Prospectus  and  Statement  of
Additional  Information. As an  illustration, if on the  Valuation Date the Fund
were to have securities with a market value of $95,000 and cash in the amount of
$5,000, the value of the assets  which would be transferred to  Pacific-European
Fund  would be $100,000.  If the net  asset value per  share of Pacific-European
Fund were $10 per share at the
 
                                       12
<PAGE>
close of business on the Valuation Date, the number of shares to be issued would
be 10,000 ($100,000  DIVIDED BY  $10). These 10,000  shares of  Pacific-European
Fund  would be distributed to the former  shareholders of the Fund. This example
is given for illustration  purposes only and does  not bear any relationship  to
the  dollar amounts  or shares  expected to  be involved  in the Reorganization.
Pacific-European Fund will  cause its transfer  agent to credit  and confirm  an
appropriate  number of  Pacific-European Fund  Shares to  each Fund shareholder.
Neither the Fund nor Pacific-European Fund issues stock certificates.
 
    The Closing Date will be the next business day following the Valuation Date,
or at such  other time  as the  Fund and  Pacific-European Fund  may agree.  The
consummation  of  the  Reorganization is  contingent  upon the  approval  of the
Reorganization by the  shareholders of  the Fund and  the receipt  of the  other
opinions  and certificates set forth in Sections 6,  7 and 8 of the Plan and the
occurrence of the events  described in those Sections,  certain of which may  be
waived  by the  Fund or Pacific-European  Fund. The  Plan may be  amended in any
mutually agreeable manner, except  that no amendment may  be made subsequent  to
the Meeting which would detrimentally affect the value of the shares of Pacific-
European  Fund  to be  distributed.  Piper Capital  will  bear all  direct costs
associated with the Reorganization  including preparation, printing, filing  and
proxy  solicitation  expenses incurred  in  connection with  obtaining requisite
shareholder approval of the Reorganization.
 
    The Plan may  be terminated and  the Reorganization abandoned  at any  time,
before  or after approval by  the Fund's shareholders, by  mutual consent of the
Fund and Pacific-European Fund. In addition, either party may terminate the Plan
upon the occurrence of a material breach of  the Plan by the other party or,  if
by  September  15,  1996, any  condition  set forth  in  the Plan  has  not been
fulfilled or waived by the party entitled to its benefits.
 
    The effect of the Reorganization is  that shareholders of the Fund who  vote
their  shares in favor of the Plan are electing to sell their shares of the Fund
(at net  asset  value  on the  Valuation  Date)  and reinvest  the  proceeds  in
Pacific-European Fund at net asset value and without recognition of taxable gain
or  loss for Federal income tax purposes.  Prior to the Valuation Date, the Fund
will declare and pay a dividend to distribute all of its accumulated  investment
company  taxable  income and  net capital  gain,  if any.  The proceeds  of such
distribution may  be taxable  to  Fund shareholders.  See  "Tax Aspects  of  the
Reorganization"  below. All contracts entered  into by or on  behalf of the Fund
will terminate upon consummation of the Reorganization.
 
    Shareholders of the Fund will continue to be able to redeem their shares  at
net  asset value (subject to any  applicable CDSC) next determined after receipt
of the redemption request until the close  of business on the business day  next
preceding  the Closing Date. Redemption requests received by the Fund thereafter
will be treated as requests for redemption of shares of Pacific-European Fund.
 
TAX ASPECTS OF THE REORGANIZATION
 
    At least one but not more than 20 business days prior to the Valuation Date,
the Fund will declare and pay a  dividend or dividends which, together with  all
previous  such dividends,  will have  the effect  of distributing  to the Fund's
shareholders all of the Fund's investment company taxable income for all periods
since inception of the Fund through  and including the Valuation Date  (computed
without  regard to  any dividends  paid deduction),  and all  of the  Fund's net
capital gain, if any, realized in such periods (after reduction for any  capital
loss carry-forward).
 
    The Reorganization is intended to qualify for Federal income tax purposes as
a  tax-free reorganization under Section 368(a)(1)  of the Internal Revenue Code
of 1986, as amended (the "Code"). The Company and Piper Global have  represented
that,  to  their  best  knowledge,  there  is  no  plan  or  intention  by  Fund
shareholders to  redeem, sell,  exchange or  otherwise dispose  of a  number  of
Pacific-European  Fund Shares received in the  transaction that would reduce the
Fund shareholders'  ownership of  Pacific-European Fund  Shares to  a number  of
shares  having a value, as of the Closing Date, of less than 50% of the value of
all of the formerly outstanding Fund shares as of the same date. The Company and
Piper Global have  each further represented  that, as of  the Closing Date,  the
Fund and
 
                                       13
<PAGE>
Pacific-European  Fund  will  qualify  as  regulated  investment  companies.  In
addition, Piper Global has further  represented that Pacific-European Fund  will
qualify as a regulated investment company for its current fiscal year.
 
    As  a condition  to the Reorganization,  the Fund  and Pacific-European Fund
will receive an opinion  of Gordon Altman Butowsky  Weitzen Shalov & Wein  that,
based  on  certain assumptions,  facts,  the terms  of  the Plan  and additional
representations set  forth in  the Plan  or provided  by the  Company and  Piper
Global:
 
         1.  The transfer of substantially all  of the Fund's assets in exchange
    for Pacific-European Fund Shares and the assumption by Pacific-European Fund
    of certain stated liabilities  of the Fund followed  by the distribution  by
    the  Fund  of  Pacific-European  Fund Shares  to  the  Fund  Shareholders in
    exchange for their Fund shares will constitute a "reorganization" within the
    meaning of Section 368(a)(1) of the Code, and the Fund and  Pacific-European
    Fund  will  each be  a "party  to  a reorganization"  within the  meaning of
    Section 368(b) of the Code;
 
         2. No gain or loss will be recognized by Pacific-European Fund upon the
    receipt of the assets  of the Fund solely  in exchange for  Pacific-European
    Fund  Shares  and  the assumption  by  Pacific-European Fund  of  the stated
    liabilities of the Fund;
 
         3. No gain or loss will be recognized by the Fund upon the transfer  of
    the   assets  of  the   Fund  to  Pacific-European   Fund  in  exchange  for
    Pacific-European Fund Shares and the assumption by Pacific-European Fund  of
    the  stated liabilities  or upon  the distribution  of Pacific-European Fund
    Shares to the Fund's shareholders in exchange for their Fund shares;
 
         4. No gain or loss will be recognized by the Fund shareholders upon the
    exchange of the shares of the Fund for Pacific-European Fund Shares;
 
         5. The aggregate tax basis for Pacific-European Fund Shares received by
    each of the Fund's shareholders pursuant  to the reorganization will be  the
    same  as the aggregate tax basis of the shares in the Fund held by each such
    shareholder of the Fund immediately prior to the Reorganization;
 
         6. The holding period of Pacific-European Fund Shares to be received by
    each shareholder of the Fund will include the period during which the shares
    in the Fund surrendered in exchange therefor were held (provided such shares
    in the Fund were held as capital assets on the date of the Reorganization);
 
         7. The tax basis of the assets of the Fund acquired by Pacific-European
    Fund will  be  the  same as  the  tax  basis  of such  assets  to  the  Fund
    immediately prior to the Reorganization; and
 
         8.  The  holding period  of  the assets  of the  Fund  in the  hands of
    Pacific-European Fund will include the period during which those assets were
    held by the Fund.
 
    The Reorganization will be treated as a "change in ownership" under  Section
382 of the Code. It is not anticipated that any resulting limitations on the use
of  any capital loss carryovers  of the Fund will  be material. In addition, the
economic benefit of any capital loss  carryovers of the Fund would be  available
to   shareholders  of   the  combined  entity   with  a   resulting  benefit  to
Pacific-European Fund shareholders. It is not anticipated that any such  benefit
will be material.
 
    SHAREHOLDERS  OF THE  FUND SHOULD CONSULT  THEIR TAX  ADVISERS REGARDING THE
EFFECT, IF  ANY,  OF THE  PROPOSED  TRANSACTION  IN LIGHT  OF  THEIR  INDIVIDUAL
CIRCUMSTANCES.  BECAUSE  THE FOREGOING  DISCUSSION ONLY  RELATES TO  THE FEDERAL
INCOME TAX CONSEQUENCES OF  THE PROPOSED TRANSACTION,  SHAREHOLDERS OF THE  FUND
SHOULD  ALSO CONSULT THEIR TAX ADVISORS AS  TO STATE AND LOCAL TAX CONSEQUENCES,
IF ANY, OF THE PROPOSED TRANSACTION.
 
DISSENTERS' RIGHTS
 
    Pursuant to  Sections  302A.471  and  302A.473  of  the  Minnesota  Business
Corporation  Act (the "MBCA Sections"), record  holders of shares of the Company
are entitled to assert dissenters' rights in connection with the  Reorganization
and  obtain payment  of the  "fair value"  of their  shares, provided  that such
shareholders comply with the requirements of the MBCA Sections.  NOTWITHSTANDING
THE
 
                                       14
<PAGE>
PROVISIONS  OF THE MBCA  SECTIONS, THE DIVISION OF  INVESTMENT MANAGEMENT OF THE
COMMISSION HAS TAKEN THE POSITION  THAT ADHERENCE TO STATE APPRAISAL  PROCEDURES
BY   A  REGISTERED  INVESTMENT  COMPANY   ISSUING  REDEEMABLE  SECURITIES  WOULD
CONSTITUTE A VIOLATION OF RULE 22C-1 UNDER THE 1940 ACT. THIS RULE PROVIDES THAT
NO OPEN-END INVESTMENT  COMPANY MAY REDEEM  ITS SHARES OTHER  THAN AT NET  ASSET
VALUE  NEXT COMPUTED AFTER RECEIPT OF A  TENDER OF SUCH SECURITY FOR REDEMPTION.
IT IS THE VIEW OF THE DIVISION OF INVESTMENT MANAGEMENT THAT RULE 22C-1 PREEMPTS
APPRAISAL PROVISIONS IN STATE STATUTES.
 
    In the interests of ensuring equal  valuation of all interests in the  Fund,
the  Company will determine dissenters' rights in accordance with the Division's
interpretation. It should be  emphasized that Fund  shareholders may sell  their
shares  at net asset value (subject to any applicable CDSC) at any time prior to
the Closing Date.
 
DESCRIPTION OF SHARES
 
    Shares of Pacific-European Fund to be issued pursuant to the Plan will, when
issued,  be  fully  paid  and   non-assessable  by  Pacific-European  Fund   and
transferable  without  restrictions and  will have  no preemptive  or conversion
rights.

         COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS
 
INVESTMENT OBJECTIVES AND POLICIES
 
    The Fund and Pacific-European Fund have a similar investment objective.  The
Fund's  objectives are long-term  capital appreciation and,  to a lesser extent,
current income. The investment objective  of Pacific-European Fund is  long-term
capital  appreciation.  Current  income  is incidental  to  this  objective. The
investment objective of the Fund is  fundamental and may not be changed  without
shareholder  approval.  The  investment objective  of  Pacific-European  Fund is
non-fundamental  and,  accordingly,  it  may  be  changed  without   shareholder
approval. If there is a change in investment objective of Pacific-European Fund,
shareholders  would need  to consider  whether Pacific-European  Fund remains an
appropriate investment in  light of  their then current  financial position  and
needs.
 
    The  Fund  seeks to  achieve its  investment  objective by  investing, under
normal circumstances, at least 65% of  its total assets in securities issued  by
issuers in Europe (including up to 10% in Eastern Europe). Emphasis is placed on
investment  in equity securities; however, the  Fund may invest without limit in
investment grade debt securities of governmental and private issuers  (including
notes,  debentures,  Brady  Bonds, mortgage-backed  securities  and asset-backed
securities). Pacific-European Fund seeks to achieve its investment objective  by
investing,  under  normal circumstances,  at least  65% of  its total  assets in
Common Stock of companies in the  Pacific Basin or in Europe (including  Eastern
Europe).  "Common Stock" means common stock  and foreign equity securities which
are substantially  similar to  common stock  in the  U.S. and  does not  include
preferred  stock or convertible debt securities).  Up to 25% of Pacific-European
Fund's total assets may be  invested in other areas of  the world to the  extent
significant opportunities for long-term capital appreciation
 
                                       15
<PAGE>
outside  of the Pacific Basin and Europe become available. Pacific-European Fund
invests in debt securities solely for temporary defensive purposes. As discussed
above, the principal difference between  the two funds is that  Pacific-European
Fund  invests in  countries that comprise  the Pacific  Basin (namely, Malaysia,
Pakistan, Sri Lanka, the Philippines,  Singapore, South Korea, Thailand,  India,
Indonesia,  Hong  Kong, Japan,  Taiwan, Australia  and  New Zealand)  and Europe
(including Eastern Europe), whereas the Fund invests primarily in Europe.
 
    As of  February  29,  1996, approximately  67%  of  Pacific-European  Fund's
investments  were  in  companies  in the  Pacific  Basin  (including  Japan) and
approximately 28% were in companies  in Europe. While Pacific-European Fund  has
no  specific policy or restriction on the allocation of its funds between Europe
and the Pacific Basin, Piper Capital and EFM believe that the opportunities  for
long-term  capital appreciation in  the Pacific Basin  are generally superior to
those presently available in  the economically more mature  areas of the  world.
The relative emphasis of Pacific-European Fund's investments between the Pacific
Basin and Europe may change over time.
 
    Both  the Fund  and Pacific-European  Fund may invest  part or  all of their
respective assets  in  U.S.  dollar- or  foreign  currency-denominated  cash  or
domestic  or  foreign  high-quality  money  market  instruments  to  maintain  a
temporary "defensive" posture, when, in  the opinion of the investment  adviser,
it is advisable to do so because of market conditions.
 
    The  Fund  and  Pacific-European  Fund  may  invest  in  American Depository
Receipts ("ADRs"), European Depository Receipts ("EDRs") and in other investment
companies (up to  the limits  prescribed by  the 1940  Act). The  Fund may  also
invest  up to 10% of its total assets in foreign index linked instruments and in
loan participations and  assignments; Pacific-European Fund  does not invest  in
these types of securities.
 
    The  Fund may purchase and sell put  and call options, futures contracts and
options on futures contracts  with respect to  financial instruments, stock  and
interest rate indexes and foreign currencies. Futures and options may be used to
facilitate  allocation of the Fund's investment among asset classes, to generate
income or to hedge against declines in securities prices or increases in  prices
of  securities proposed to be purchased.  Pacific-European Fund may, for hedging
purposes only, buy or sell  put and call options on  the securities in which  it
may  invest and  enter into futures  contracts and options  on futures contracts
based on financial indices including any  index of securities in which the  Fund
may  invest. Both funds may  buy or sell options,  futures or options on futures
that are traded on U.S. or  foreign exchanges or over-the-counter. In  addition,
both  funds  may enter  into currency  exchange transactions  (including forward
foreign currency exchange contracts and futures and options contracts on foreign
currencies), as a hedge against fluctuations in foreign exchange rates.
 
    Both the  Fund  and  Pacific-European  Fund may  purchase  securities  on  a
when-issued  or delayed delivery basis and may  purchase or sell securities on a
forward commitment basis. Both funds may invest in warrants up to 5% of its  net
assets.  Included within this amount,  but not to exceed 2%  of the value of its
net assets, may  be warrants that  are not listed  on the New  York or  American
Stock  Exchange. Warrants are, in effect,  options to purchase equity securities
at a specific  price, during  a specific  period, and  have no  voting or  other
rights  with respect to the corporation issuing  them and pay no dividends. Both
funds may  enter  into  repurchase  agreements  subject  to  certain  procedures
designed  to minimize risks associated with such agreements. Although both funds
may enter  into  reverse  repurchase  agreements, neither  Fund  has,  nor  does
Pacific-European   Fund  have  any  current  intention  of  entering  into  such
agreements in the  future. The Fund  may invest in  zero coupon bonds,  deferred
interest  bonds and  PIK Bonds; Pacific-European  Fund does not  invest in these
types of instruments.
 
    In addition, the  Fund is  a non-diversified investment  company within  the
meaning  of  the  1940  Act,  whereas  Pacific-European  Fund  is  a diversified
investment company. A  non-diversified investment company  may invest a  greater
portion  of its assets in  the securities of a  single issuer than a diversified
investment company.  To  the extent  that  a  relatively high  percentage  of  a
non-diversified
 
                                       16
<PAGE>
fund's  assets may be invested in the securities of a limited number of issuers,
such fund  may  be  more  susceptible  to  any  single  economic,  political  or
regulatory  occurrence than the portfolio securities of a diversified investment
company.
 
    The investment  policies of  both  the Fund  and Pacific-European  Fund  are
non-fundamental  and  may be  changed by  their  respective Boards  of Directors
unless otherwise noted  herein. The  foregoing discussion  is a  summary of  the
principal  differences and similarities  between the investment  policies of the
funds. For a more  complete discussion of each  fund's policies see  "Investment
Objective  and Policies"  in each  fund's respective  Prospectus and "Investment
Objectives and Policies" in the  Fund's Statement of Additional Information  and
"Investment  Objective,  Policies and  Restrictions" in  Pacific-European Fund's
Statement of Additional Information.
 
INVESTMENT RESTRICTIONS
 
    The investment restrictions adopted by the Fund and Pacific-European Fund as
fundamental policies appear under the  caption "Investment Restrictions" in  the
Prospectus  and Statement  of Additional  Information of  the Fund  and "Special
Investment  Methods  --  Investment  Restrictions"  in  Pacific-European  Fund's
Prospectus  and "Investment  Objective, Policies  and Restrictions"  in Pacific-
European Fund's Statement  of Additional Information.  A fundamental  investment
restriction  cannot be changed without the vote of a majority of the outstanding
voting securities  of  a  fund,  as  defined  in  the  1940  Act.  The  material
differences  are  as  follows:  As a  diversified  investment  company, Pacific-
European Fund may not, as a matter of fundamental policy, with respect to 75% of
its total assets, invest more  than 5% of the value  of its total assets in  the
securities  of any  one issuer or  own more  than 10% of  the outstanding voting
securities of any one issuer (other than obligations issued or guaranteed by the
U.S. Government, its agencies  or instrumentalities). The Fund  is subject to  a
similar non-fundamental limitation only with respect to 50% of its assets. While
both  funds are prohibited from making short  sales, the Fund is subject to such
limitation on a non-fundamental  basis. As a  fundamental restriction, both  the
Fund and Pacific-European Fund may not purchase real estate or interests therein
other  than securities backed by mortgages and similar investments; however, the
Fund may purchase readily marketable interests in real estate investment  trusts
or  readily marketable  securities of companies  that invest in  real estate. In
addition, the Fund  has a  fundamental restriction prohibiting  the purchase  of
real  estate  limited  partnership interests  whereas  Pacific-European  Fund is
subject to the same limitation on a non-fundamental basis.

                      AGREEMENT AND PLAN OF REORGANIZATION
         HERCULES EUROPEAN VALUE FUND AND PACIFIC-EUROPEAN GROWTH FUND
 
    THIS  AGREEMENT AND PLAN OF REORGANIZATION  ("Agreement") is made as of this
15th day  of  April,  1996,  by  and  between  Hercules  Funds  Inc.  ("Hercules
Company"),  on  behalf of  its series  Hercules  European Value  Fund ("Hercules
Fund"), and Piper Global Funds Inc.  ("Piper Company"), on behalf of its  series
Pacific-European  Growth Fund ("Piper Fund"). Hercules Company and Piper Company
are Minnesota corporations. As  used in this Agreement,  the terms "Piper  Fund"
and  "Hercules Fund" shall be construed to mean, respectively, 'Piper Company on
behalf of Piper Fund' and 'Hercules  Company on behalf of Hercules Fund',  where
necessary  to reflect the  fact that a corporate  series is generally considered
the beneficiary of corporate level actions taken with respect to the series  and
is not itself recognized as a person under law.
 
    This   Agreement  is  intended  to   be  and  is  adopted   as  a  "plan  of
reorganization"  within  the   meaning  of   Treas.  Reg.   1.368-2(g),  for   a
reorganization  under Section 368(a)(1) of the Internal Revenue Code of 1986, as
amended (the "Code"). The reorganization ("Reorganization") will consist of  the
transfer  to Piper Fund of  substantially all of the  assets of Hercules Fund in
exchange for the assumption by Piper Fund of all stated liabilities of  Hercules
Fund  and the issuance by Piper Fund of  shares of common stock, par value $0.01
per share  ("Piper Fund  Shares"), to  be distributed,  after the  Closing  Date
hereinafter  determined, to the shareholders of  Hercules Fund in liquidation of
Hercules Fund as provided herein, all upon the terms and conditions  hereinafter
set  forth in this Agreement. The distribution  of Piper Fund Shares to Hercules
Fund shareholders and the  retirement and cancellation  of Hercules Fund  shares
will  be effected pursuant to  an amendment to the  Articles of Incorporation of
Hercules Company in the form attached hereto as Exhibit 1 (the "Amendment"),  to
be  adopted  by  Hercules  Company in  accordance  with  the  Minnesota Business
Corporation Act.
 
    In consideration  of  the  premises  and of  the  covenants  and  agreements
hereinafter set forth, the parties hereto covenant and agree as follows:
 
1.  THE REORGANIZATION AND LIQUIDATION OF HERCULES FUND
 
    1.1.    Subject to  the terms  and conditions  set forth  herein and  in the
Amendment and  on the  basis  of the  representations and  warranties  contained
herein,  Hercules  Fund agrees  to assign,  deliver  and otherwise  transfer the
Hercules Fund Assets (as  defined in paragraph 1.2(a))  to Piper Fund and  Piper
Fund  agrees in exchange  therefor to assume all  stated liabilities of Hercules
Fund on the Closing Date (as defined in paragraph 3.1) as set forth in paragraph
1.3 and to deliver to Hercules  Fund Shareholders (as defined in paragraph  1.5)
the  number  of  Piper  Fund Shares,  including  fractional  Piper  Fund Shares,
determined in accordance with paragraph 2.2. Such transactions shall take  place
at the closing provided for in paragraph 3.1 ("Closing").
 
    1.2.(a)  The "Hercules Fund Assets" shall consist of all property including,
    without limitation,  all cash,  cash equivalents,  securities,  commodities,
    futures,  and dividend and interest receivables  owned by Hercules Fund, and
    any deferred or prepaid expenses shown as an asset on Hercules Fund's books,
    on the Valuation Date (as defined in paragraph 2.1).
 
        (b) Hercules Fund reserves  the right to sell  any of the securities  in
    its  portfolio but will not, from the  date on which the Proxy Materials (as
    defined in paragraph 4.3) are mailed to Hercules Fund shareholders,  acquire
    without the prior approval of Piper Fund, any additional securities or other
    instruments  other than securities or instruments of the type in which Piper
    Fund is permitted to invest and in  amounts agreed to by Piper Fund. In  the
    event  that Hercules Fund holds any assets  that Piper Fund is not permitted
    to hold,  Hercules Fund  will dispose  of such  assets on  or prior  to  the
    Valuation  Date. In  addition, if  it is  determined that  the portfolios of
    Hercules Fund and  Piper Fund,  when aggregated,  would contain  investments
    exceeding  certain  percentage  limitations  imposed  upon  Piper  Fund with
    respect to such investments (including,
 
                                      A-1
<PAGE>
    among   others,   percentage   limitations   necessary   to   satisfy    the
    diversification  requirements of  the Code),  Hercules Fund  if requested by
    Piper Fund  will, on  or prior  to  the Valuation  Date, dispose  of  and/or
    reinvest  a sufficient  amount of  such investments  as may  be necessary to
    avoid violating such limitations as of the Closing Date.
 
    1.3.  Hercules Fund  will endeavor to discharge  all of its liabilities  and
obligations on or prior to the Valuation Date. Piper Fund will assume all stated
liabilities, which include, without limitation, all expenses, costs, charges and
reserves  reflected  on  an unaudited  Statement  of Assets  and  Liabilities of
Hercules Fund prepared  by the Treasurer  of Hercules Fund  as of the  Valuation
Date  in accordance  with generally accepted  accounting principles consistently
applied from the prior audited period ("Valuation Date Statement").
 
    1.4.  In order  for Hercules Fund  to comply with  Section 852(a)(1) of  the
Code  and to avoid having  any investment company taxable  income or net capital
gain (as defined in Sections 852(b)(2)  and 1222(11) of the Code,  respectively)
in the taxable year ending with its dissolution, Hercules Fund will on or before
the  Valuation Date (a) declare a dividend in  an amount large enough so that it
will have declared dividends of all of its investment company taxable income and
net capital gain, if  any, for such taxable  year (determined without regard  to
any deduction for dividends paid) and (b) distribute such dividend.
 
    1.5.   On the Closing Date or as soon as practicable thereafter, pursuant to
paragraph 1.1 hereof and the Amendment, Hercules Fund will distribute Piper Fund
Shares received  by  Hercules  Fund  pro rata  to  its  shareholders  of  record
determined  as of the  close of business  on the Valuation  Date ("Hercules Fund
Shareholders"). Thereafter, no additional  shares representing interests in  the
Hercules  Fund shall  be issued.  Such distribution  will be  accomplished by an
instruction, signed by Hercules Fund's Secretary, to transfer Piper Fund  Shares
then  credited to  Hercules Fund's account  on the  books of Piper  Fund to open
accounts on  the  books  of  Piper  Fund in  the  names  of  the  Hercules  Fund
Shareholders  and  representing the  respective pro  rata  number of  Piper Fund
Shares due  each such  Hercules  Fund Shareholder.  All issued  and  outstanding
shares  of  Hercules Fund  simultaneously will  be  canceled on  Hercules Fund's
books. No  Hercules Fund  Shareholder will  be charged  any contingent  deferred
sales  charge described in Hercules Fund's current or then-current prospectus as
a result of  the conversion  of Hercules Fund  holdings into  Piper Fund  Shares
described in this paragraph.
 
    1.6.   Ownership of  Piper Fund Shares will  be shown on  the books of Piper
Fund's transfer agent. Piper Fund Shares will be issued in the manner  described
in Piper Fund's then current Prospectus and Statement of Additional Information,
except no front-end sales charges will be incurred by Hercules Fund Shareholders
in connection with Piper Fund Shares received in the Reorganization.
 
    1.7.   Any transfer  taxes payable upon  issuance of Piper  Fund Shares in a
name other than the registered holder of Hercules Fund Shares on Hercules Fund's
books as of the close of business on the Valuation Date shall, as a condition of
such issuance and transfer, be paid by the person to whom Piper Fund Shares  are
to be issued and transferred.
 
    1.8.   Any reporting responsibility of Hercules Fund is and shall remain the
responsibility of Hercules Fund up to  and including the date on which  Hercules
Fund is dissolved and deregistered pursuant to paragraph 1.9.
 
    1.9.   Hercules  Company shall be  dissolved as a  Minnesota corporation and
deregistered as an investment company under the Investment Company Act of  1940,
as  amended ("1940  Act"), promptly  following the  making of  all distributions
pursuant to paragraph 1.5 and the  reorganization or liquidation of each of  its
series, such that no shares of Hercules Company remain issued and outstanding.
 
    1.10.   All books and records maintained  on behalf of Hercules Fund will be
delivered to Piper Fund and, after the Closing, will be maintained by Piper Fund
or its  designee in  compliance with  applicable record  retention  requirements
under the 1940 Act.

2.  VALUATION
 
    2.1.   The "Valuation Date"  shall be a business day  not later than the 5th
business day following the receipt of  the requisite approval of this  Agreement
by  shareholders  of Hercules  Fund or  such other  date after  such shareholder
approval as may be mutually agreed upon.  The value of the Hercules Fund  Assets
shall be the value of such assets computed as of 4:00 p.m., Eastern time, on the
Valuation  Date, using the  valuation procedures set forth  in Piper Fund's then
current Prospectus and Statement of Additional Information.
 
    2.2.  The net asset value of a Piper Fund Share shall be the net asset value
per share computed  on the Valuation  Date, using the  valuation procedures  set
forth  in  Piper  Fund's then  current  Prospectus and  Statement  of Additional
Information.
 
    2.3.  The number of Piper Fund Shares (including fractional shares, if  any)
to be issued hereunder shall be determined by dividing the value of the Hercules
Fund  Assets, net  of the  liabilities of  Hercules Fund  assumed by  Piper Fund
pursuant to paragraph 1.1, determined in  accordance with paragraph 2.1, by  the
net  asset value of a  Piper Fund Share determined  in accordance with paragraph
2.2.
 
    2.4.  All computations  of value shall be  made by Piper Capital  Management
Incorporated  ("PCM") in accordance  with its regular  practice in pricing Piper
Fund. Piper Fund shall cause  PCM to deliver a copy  of its valuation report  at
the Closing.
 
3.  CLOSING AND CLOSING DATE
 
    3.1.   The Closing shall  take place on the Valuation  Date as of 5:00 p.m.,
Eastern time,  or at  such other  day  or time  as the  parties may  agree  (the
"Closing  Date"). The Closing shall be held  in a location mutually agreeable to
the parties hereto. All acts taking place at the Closing shall be deemed to take
place simultaneously as of 5:00 p.m.,  Eastern time, on the Closing Date  unless
otherwise provided.

other assets) shall be delivered by  Hercules Fund to Investors Fiduciary  Trust
Company (the "Custodian"), as custodian for Piper Fund, for the account of Piper
Fund  on  or  before the  Closing  Date  in conformity  with  applicable custody
provisions under the 1940 Act and duly  endorsed in proper form for transfer  in
such  condition as  to constitute good  delivery thereof in  accordance with the
custom of  brokers.  The  portfolio  securities  shall  be  accompanied  by  all
necessary federal and state stock transfer stamps or a check for the appropriate
purchase  price of such  stamps. Portfolio securities  and instruments deposited
with a securities depository (as defined in Rule 17f-4 under the 1940 Act) shall
be delivered on  or before  the Closing Date  by book-entry  in accordance  with
customary  practices of  such depository and  the Custodian.  The cash delivered
shall be in the form of a Federal Funds wire, payable to the order of "Investors
Fiduciary Trust Company, Custodian for Piper Growth and Income Fund, a series of
Piper Funds, Inc."
 
    3.3.   In the  event that  on the  Valuation Date,  (a) the  New York  Stock
Exchange  shall be closed to  trading or trading thereon  shall be restricted or
(b) trading or the reporting of trading  on such Exchange or elsewhere shall  be
disrupted  so  that, in  the  judgment of  both  Piper Fund  and  Hercules Fund,
accurate appraisal of the value of the net assets of Piper Fund or the  Hercules
Fund  Assets is impracticable,  the Valuation Date shall  be postponed until the
first business day  after the  day when trading  shall have  been fully  resumed
without restriction or disruption and reporting shall have been restored.
 
    3.4.   At the Closing,  each party shall deliver to  the other such bills of
sale, checks,  assignments,  share  certificates,  if  any,  receipts  or  other
documents as such other party or its counsel may reasonably request.

    adversely affect its financial condition or the conduct of its business; and
    Hercules  Fund  knows  of  no  facts  that  might  form  the  basis  for the
    institution of such  proceedings and is  not a  party to or  subject to  the
    provisions  of any  order, decree or  judgment of any  court or governmental
    body which  materially and  adversely affects,  or is  reasonably likely  to
    materially  and adversely affect, its business  or its ability to consummate
    the transactions herein contemplated;
 
        (g) Hercules Fund's  Statement of Assets  and Liabilities, Statement  of
    Operations,  Statement of Changes in Net  Assets and Financial Highlights of
    Hercules Fund as of June 30, 1995 and for the year then ended, certified  by
    KPMG  Peat Marwick LLP  (copies of which  have been or  will be furnished to
    Piper Fund)  fairly  present,  in all  material  respects,  Hercules  Fund's
    financial  condition as of such date, and its results of operations, changes
    in its net  assets and financial  highlights for such  period in  accordance
    with  generally accepted  accounting principles, and  as of  such date there
    were no known  liabilities of  Hercules Fund (contingent  or otherwise)  not
    disclosed  therein  that  would  be required  in  accordance  with generally
    accepted accounting principles to be disclosed therein;
 
        (h) Since  the date  of the  most recent  audited financial  statements,
    there  has not been any material adverse change in Hercules Fund's financial
    condition, assets, liabilities or business, other than changes occurring  in
    the  ordinary  course of  business, or  any incurrence  by Hercules  Fund of
    indebtedness maturing more than one year from the date such indebtedness was
    incurred, except as otherwise  disclosed in writing  to and acknowledged  by
    Piper  Fund prior  to the date  of this  Agreement and prior  to the Closing
    Date. All  liabilities  of  Hercules Fund  (contingent  and  otherwise)  are
    reflected  in  the  Valuation  Date  Statement.  For  the  purpose  of  this
    subparagraph (h), neither a decline in  Hercules Fund's net asset value  per
    share  nor a decrease in Hercules Fund's size due to redemptions by Hercules
    Fund shareholders shall constitute a material adverse change;
 
        (i) Hercules Fund has no material contracts or other commitments  (other
    than  this Agreement) that will be terminated  with liability to it prior to
    the Closing Date;
 
        (j)  All issued and outstanding shares of Hercules Fund are, and at  the
    Closing  Date will be,  duly and validly issued  and outstanding, fully paid
    and nonassessable  with no  personal liability  attaching to  the  ownership
    thereof.  Hercules Fund does  not have outstanding  any options, warrants or
    other rights to subscribe for  or purchase any of  its shares, nor is  there
    outstanding  any security convertible to any  of its shares. All such shares
    will, at the  time of Closing,  be held by  the persons and  in the  amounts
    recorded by Hercules Fund's transfer agent;
 
        (k)  The execution, delivery and performance of this Agreement will have
    been duly authorized prior  to the Closing Date  by all necessary action  on
    the part of Hercules Company, and subject to the approval of Hercules Fund's
    shareholders,  this Agreement constitutes a  valid and binding obligation of
    Hercules Fund  enforceable  in accordance  with  its terms,  subject  as  to
    enforcement   to   bankruptcy,   insolvency,   reorganization,   moratorium,
    fraudulent conveyance, and  other laws  relating to  or affecting  creditors
    rights  and to general equity  principles. No other consents, authorizations
    or approvals are necessary in connection with Hercules Fund's performance of
    this Agreement, except such  as have been obtained  under the 1933 Act,  the
    1934 Act and the 1940 Act and such as may be required under state securities
    laws;

        (l)  All material federal and other  tax returns and reports of Hercules
    Fund required by law to  be filed on or before  the Closing Date shall  have
    been  filed and are correct and all federal  and other taxes shown as due or
    required to be shown as  due on said returns and  reports have been paid  or
    provision has been made for the payment thereof, and to the best of Hercules
    Fund's  knowledge, no such return is currently under audit and no assessment
    has been asserted with  respect to any  such return and  there are no  facts
    that might form the basis for such proceedings;
 
        (m) For each taxable year since its inception, Hercules Fund has met all
    the requirements of Subchapter M of the Code for qualification and treatment
    as  a "regulated investment  company" and neither  the execution or delivery
    of, nor  the  performance of  its  obligations under,  this  Agreement  will
    adversely  affect,  and no  other  events, to  the  best of  Hercules Fund's
    knowledge, are reasonably likely  to occur which  will adversely affect  the
    ability  of Hercules Fund to continue to meet the requirements of Subchapter
    M of the Code;
 
        (n) At the Closing Date, Hercules Fund will have good and valid title to
    the Hercules Fund Assets, subject to no liens (other than the obligation, if
    any, to pay the purchase price of portfolio securities purchased by Hercules
    Fund which have not settled prior  to the Closing Date), security  interests
    or  other  encumbrances,  and full  right,  power and  authority  to assign,
    deliver and otherwise transfer such assets hereunder, and upon delivery  and
    payment  for such assets, Piper Fund  will acquire good and marketable title
    thereto, subject to no restrictions on the full transfer thereof,  including
    any restrictions as might arise under the 1933 Act;
 
        (o)  On the effective date of the Registration Statement, at the time of
    the meeting of  Hercules Fund's shareholders  and on the  Closing Date,  the
    Proxy Materials will (i) comply in all material respects with the provisions
    of  the 1933  Act, the  Securities Exchange Act  of 1934,  as amended ("1934
    Act") and the 1940 Act and  the regulations thereunder and (ii) not  contain
    any  untrue statement of  a material fact  or omit to  state a material fact
    required to be stated  therein or necessary to  make the statements  therein
    not  misleading.  Neither  Hercules  Fund  nor  Hercules  Company  shall  be
    construed to have made the foregoing representation with respect to portions
    of the  Proxy  Materials furnished  by  Piper Fund.  Any  other  information
    furnished  by Hercules Fund for use in  the Registration Statement or in any
    other manner  that may  be  necessary in  connection with  the  transactions
    contemplated  hereby shall be accurate and  complete and shall comply in all
    material respects  with applicable  federal securities  and other  laws  and
    regulations thereunder;
 
        (p)  Hercules Fund has maintained or has  caused to be maintained on its
    behalf all books and accounts as required of a registered investment company
    in compliance with the requirements  of Section 31 of  the 1940 Act and  the
    Rules thereunder; and
 
        (q)  Hercules  Fund is  not  acquiring Piper  Fund  Shares to  be issued
    hereunder for the purpose of making  any distribution thereof other than  in
    accordance with the terms of this Agreement.

    The  undersigned  officer of  Hercules  Funds Inc.  ("Hercules  Company"), a

hereby certifies  that Hercules  Company's (a)  Board of  Directors, by  written
action  dated March 29, 1996,  and (b) shareholders, at  a meeting held June 18,

    WHEREAS, Hercules Company is registered as an open-end management investment
company (I.E.,  a mutual  fund) under  the Investment  Company Act  of 1940  and
offers  its shares to the  public in several series,  each of which represents a
separate and distinct portfolio of assets; and
 
    WHEREAS, it is  desirable and in  the best  interest of the  holders of  the
Hercules  European Value Fund  ("Hercules Fund"), a  series of Hercules Company,
that the assets belonging to such series, subject to its stated liabilities,  be
sold  to Pacific-European Growth  Fund ("Piper Fund"), a  series of Piper Global
Funds Inc. ("Piper Company"), a Minnesota corporation and an open-end management
investment company  registered under  the  Investment Company  Act of  1940,  in
exchange for shares of Piper Fund; and
 
    WHEREAS, Hercules Company wishes to provide for the PRO RATA distribution of
such  shares of Piper Fund received by it  to holders of shares of Hercules Fund
and the simultaneous cancellation  and retirement of  the outstanding shares  of
Hercules Fund; and
 
    WHEREAS,  Hercules Company and Piper Company  have entered into an Agreement
and Plan of Reorganization providing for the foregoing transactions; and
 
    WHEREAS, the Agreement and Plan of Reorganization requires that, in order to
bind all shareholders  of Hercules Fund  to the foregoing  transactions, and  in
particular  to bind such shareholders to  the cancellation and retirement of the
outstanding shares of Hercules  Fund, it is necessary  to adopt an amendment  to
Hercules Company's Articles of Incorporation.
 
    NOW,  THEREFORE,  BE  IT  RESOLVED,  that  Hercules  Company's  Articles  of
Incorporation be, and the same hereby are, amended to add the following  Article
5B immediately following Article 5 thereof:
 
    5B. (a)  For purposes of this Article 5B, the following terms shall have the
    following meanings:
 
        "HERCULES COMPANY" means the Corporation.
 
        "PIPER COMPANY" means Piper Global Funds Inc., a Minnesota corporation.
 
        "ACQUIRED FUND" means Hercules  Company's Hercules European Value  Fund,
    the Series B Shares of the Corporation.
 
        "ACQUIRING FUND" means Piper Company's Pacific-European Growth Fund.
 
        "VALUATION  DATE" means the day established in the Agreement and Plan of
    Reorganization, as  the day  upon which  the value  of the  Acquired  Fund's
    assets is determined for purposes of the reorganization.
 
        "CLOSING  DATE" means 9:00  a.m. on the next  business day following the
    Valuation Date or such other date and  time set forth in the pertinent  plan
    of  reorganization or liquidation, as the  case may be, for the consummation
    of the reorganization or liquidation.
 
        (b) At the Closing Date, the assets belonging to the Acquired Fund,  the
    Special  Liabilities associated with such assets, and the General Assets and
    General Liabilities allocated  to the Acquired  Fund, shall be  sold to  and
    assumed   by   the   Acquiring   Fund   in   return   for   Acquiring   Fund
<PAGE>
    shares, all  pursuant  to the  Agreement  and Plan  of  Reorganization.  For
    purposes  of  the  foregoing,  the  terms  "assets  belonging  to", "Special
    Liabilities", "General Assets", and "General Liabilities" have the  meanings
    assigned  to  them  in Article  7(b),  (c),  and (d)  of  Hercules Company's
    Articles of Incorporation.
 
        (c) The number of Acquiring Fund  shares to be received by the  Acquired
    Fund  and  distributed by  it  to the  Acquired  Fund shareholders  shall be
    determined as follows:
 
           (i) The value of the Acquired  Fund's assets and the net asset  value
       per  share of  the Acquiring  Fund's shares shall  be computed  as of the
       Valuation Date using the valuation procedures set forth in the  Acquiring
       Fund's  then-current Prospectus and  Statement of Additional Information,
       and as may be required by the Investment Company Act of 1940, as  amended
       (the "1940 Act").
 
           (ii)  The  total  number  of  Acquiring  Fund  shares  to  be  issued
       (including  fractional  shares,  if  any)  in  exchange  for  assets  and
       liabilities  of the Acquired Fund shall be determined as of the Valuation
       Date by dividing  the value  of the Acquired  Fund's assets,  net of  its
       stated  liabilities on  the Closing Date  to be assumed  by the Acquiring
       Fund, by the  net asset  value of the  Acquiring Fund's  shares, each  as
       determined pursuant to (i) above.
 
          (iii)  On the Closing Date, or  as soon as practicable thereafter, the
       Acquired Fund shall distribute PRO RATA to its shareholders of record  as
       of  the  Valuation Date  the full  and  fractional Acquiring  Fund shares
       received by the Acquired Fund pursuant to (ii) above.
 
        (d)  The  distribution  of  Acquiring  Fund  shares  to  Acquired   Fund
    shareholders provided for in paragraph (c) above shall be accomplished by an
    instruction,  signed by Hercules Company's  Secretary, to transfer Acquiring
    Fund shares then credited to the Acquired Fund's account on the books of the
    Acquiring Fund to open accounts  on the books of  the Acquiring Fund in  the
    names  of  the  Acquired  Fund  shareholders  in  amounts  representing  the
    respective  PRO  RATA  number  of  Acquiring  Fund  shares  due  each   such
    shareholder pursuant to the foregoing provisions. All issued and outstanding
    shares of the Acquired Fund shall simultaneously be canceled on the books of
    the Acquired Fund and retired.
 
        (e)  From and after the Closing  Date, the Acquired Fund shares canceled
    and retired  pursuant  to paragraph  (d)  above  shall have  the  status  of
    authorized  and unissued Shares of  Hercules Company, without designation as
    to series.
 
    IN WITNESS WHEREOF, the undersigned officer of Hercules Company has executed
these Articles of Amendment on behalf of Hercules Company on           , 1996.

    Pacific-European  Growth Fund (the "Fund") is  a diversified series of Piper
Global Funds Inc.  ("Piper Global"), an  open-end management investment  company
the shares of which can be offered in more than one series. The Fund is the only
series  of Piper Global  currently outstanding. The  investment objective of the
Fund is long-term  capital appreciation.  Current income is  incidental to  this
objective.   The  Fund  seeks  to   achieve  its  investment  objective  through
investments primarily in Common  Stock (as herein defined)  of companies in  the
Pacific  Basin or in Europe (including Eastern  Europe). Up to 25% of the Fund's
total assets  may  be  invested in  other  areas  of the  world  to  the  extent
significant  opportunities  for long-term  capital  appreciation outside  of the
Pacific Basin and Europe  become available. The Fund  does not invest in  Common
Stock  of U.S. companies. No  assurance can be given  that the Fund's investment
objective will be achieved.
 
    Investment in the Fund involves certain risks and requires consideration  of
factors  not typically associated with investment in securities of U.S. issuers.
See "Risk Factors."
 
    This Prospectus concisely describes the information about the Fund that  you
should  know  before  investing.  Please read  the  Prospectus  carefully before
investing and retain it for future reference.

                                  INTRODUCTION
 
    Pacific-European  Growth Fund (the "Fund") is  a diversified series of Piper
Global Funds Inc. ("Piper Global"),  an open-end management investment  company,
or mutual fund, the shares of which can be offered in more than one series. Each
series  in effect represents a separate  fund with its own investment objectives
and policies. The Fund is the only series of Piper Global currently outstanding.
Piper Global was organized under the laws of the State of Minnesota in 1990 as a
closed-end investment company and converted to an open-end investment company on
August 31,  1992. The  investment objective  of the  Fund is  long-term  capital
appreciation. Current income is incidental to this objective.
 
THE INVESTMENT ADVISER
 
    The   Fund  is  managed  by   Piper  Capital  Management  Incorporated  (the
"Adviser"), a wholly owned subsidiary of  Piper Jaffray Companies Inc. The  Fund
pays the Adviser a basic management fee calculated and paid monthly at an annual
rate  of 1.00% on net assets up to $100 million, with the fee scaled downward as
assets increase in size (the "Basic Fee"). The Basic Fee (as a percentage of net
assets) is higher than that paid by  most other mutual funds. The Basic Fee  may
be increased or decreased by up to a maximum, on an annual basis, of .25% of the
Fund's  average daily  net assets  depending upon the  extent to  which the Fund
outperforms or underperforms the Morgan Stanley Capital International  European,
Australian    and    Far    East    Index    (the    "EAFE-SM-    Index").   See
"Management--Investment Adviser."
 
THE SUB-ADVISER
 
    Edinburgh  Fund  Managers   plc  acts   as  the   Fund's  sub-adviser   (the
"Sub-Adviser")  under an agreement with the Adviser. The Sub-Adviser is a public
limited company that was incorporated in 1969. It is a majority-owned subsidiary
of The British Investment  Trust PLC, a  Scottish closed-end investment  company
founded  in 1889,  for which  the Sub-Adviser  serves as  investment manager and
adviser. For its services, the Sub-Adviser is paid a fee by the Adviser equal to
65% of the Basic Fee  plus or minus 90% of  the performance fee adjustment.  See
"Management--Sub-Adviser."
 
THE DISTRIBUTOR
 
    Piper  Jaffray Inc. ("Piper  Jaffray" or the  "Distributor"), a wholly owned
subsidiary of Piper  Jaffray Companies  Inc. and  an affiliate  of the  Adviser,
serves as Distributor of the Fund's shares.
 
OFFERING PRICE
 
    Shares  of the  Fund are offered  to the  public at the  next determined net
asset value  after  receipt  of  an  order  by  a  shareholder's  Piper  Jaffray
investment executive or other broker-dealer plus a maximum sales charge of 4% of
the  offering price  (4.17% of the  net asset  value) on purchases  of less than
$100,000. The  sales charge  is reduced  on a  graduated scale  on purchases  of
$100,000 or more. FUND SHARES ARE BEING OFFERED TO THE PUBLIC WITHOUT AN INITIAL
OR  DEFERRED SALES CHARGE THROUGH JUNE 30, 1995. In connection with purchases of
$500,000 or more,  there is no  initial sales charge;  however, a 1%  contingent
deferred  sales charge will be imposed in  the event of a redemption transaction
occurring within  24 months  following such  a purchase.  See "How  to  Purchase
Shares--Public Offering Price."
 
MINIMUM INITIAL AND SUBSEQUENT INVESTMENTS
 
    The minimum initial investment for the Fund is $250. There is no minimum for
subsequent investments. See "How to Purchase Shares--Minimum Investments."
 
EXCHANGES
 
    You  may exchange your shares for shares of any other mutual fund managed by
the Adviser which is open to new  investors and eligible for sale in your  state
of  residence. All exchanges are subject  to the minimum investment requirements
and other applicable terms set forth in the prospectus of the fund whose  shares
you  acquire. You may make four exchanges  per year without payment of a service
charge. Thereafter,  there  is  a  $5 service  charge  for  each  exchange.  See
"Shareholder Services--Exchange Privilege."
 
                                       2
<PAGE>
REDEMPTION PRICE
 
    Shares of the Fund may be redeemed at any time at their net asset value next
determined  after  a  redemption  request  is  received  by  your  Piper Jaffray
investment executive or other broker-dealer. A contingent deferred sales  charge
will  be  imposed  upon the  redemption  of certain  shares  initially purchased
without a sales charge.  See "How to  Redeem Shares--Contingent Deferred  Shares
Charge."  The Fund reserves the right, upon 30 days written notice, to redeem an
account if the  net asset  value of  the shares falls  below $200.  See "How  to
Redeem Shares--Involuntary Redemption."
 
CERTAIN RISK FACTORS TO CONSIDER
 
    An  investment in  the Fund  is subject  to certain  risks, as  set forth in
detail under "Investment Objective  and Policies," "Special Investment  Methods"
and  "Risk Factors." As with other mutual  funds, there can be no assurance that
the Fund  will  achieve its  objective.  Because  the Fund  invests  in  foreign
securities,  an investment  in the Fund  requires consideration  of certain risk
factors that are not typically associated  with investing in securities of  U.S.
companies.   These   factors  include   risks   relating  to   adverse  currency
fluctuations, potential political and economic instability of certain countries,
limited  liquidity  and  volatile  prices  of  certain  securities  of  non-U.S.
companies,  and  foreign  taxation. In  addition,  the  Fund may  engage  in the
following investment  practices which  involve certain  special risks:  entering
into   currency  exchange   transactions,  forward   foreign  currency  exchange
transactions and foreign  currency futures  and options,  entering into  options
transactions  on securities in which the Fund  may invest, the use of repurchase
agreements, the lending of portfolio securities, entering into futures contracts
and options on futures contracts, the purchase of securities on a  "when-issued"
basis  and the purchase or  sale of securities on  a "forward commitment" basis.
These techniques involve certain special  risks and may increase the  volatility
of  the Fund's net asset value. The Fund may invest in illiquid securities which
will involve greater risk than investments in other securities and may  increase
Fund expenses.

    Any  questions or communications  regarding a shareholder  account should be
directed to your Piper  Jaffray investment executive or,  in the case of  shares
held through another broker-dealer, to IFTC at (800) 874-6205. General inquiries

forth on the cover page of this Prospectus.

EXAMPLE
 
    You  would pay the following  expenses on a $1,000  investment assuming a 5%
annual return and redemption at the end of each time period:
 
<TABLE>
          <S>                     <C>

           5 years............    $134
          10 years............    $243
</TABLE>
 
    The  purpose  of  the  above  Fund  Expenses  table  is  to  assist  you  in
understanding  the various  costs and expenses  that investors in  the Fund will
bear directly or indirectly.  THE EXAMPLE CONTAINED IN  THE TABLE SHOULD NOT  BE
CONSIDERED  A REPRESENTATION OF PAST OR  FUTURE EXPENSES. ACTUAL EXPENSES MAY BE
GREATER OR LESSER THAN THOSE SHOWN.
 
    The information set forth in the table is based on actual expenses  incurred
by the Fund during the fiscal year ended February 28, 1995, except that the Rule
12b-1  fees and total  fund operating expenses  have been restated  to reflect a
change in the Distributor's voluntary Rule 12b-1 fee limit for fiscal 1996.  The
Fund has adopted a Rule 12b-1 Plan under which the Fund is required to reimburse
the  Distributor for  shareholder servicing costs  and distribution  costs in an
amount not to  exceed, on an  annualized basis,  .50% of the  average daily  net
assets  of the  Fund. Of  such amount, the  Distributor may  be paid shareholder
servicing fees of  up to .25%  of the average  daily net assets  of the Fund  to
cover  shareholder servicing  costs, and distribution  fees of a  like amount to
cover distribution costs. The  Distributor has voluntarily  agreed to limit  the
fee  to an  annual rate  of .32% of  the Fund's  average daily  net assets. This
voluntary limitation may be revised or terminated at any time after fiscal  year
end. The Adviser may or may not assume additional expenses of the Fund from time
to  time, in its discretion, while retaining the ability to be reimbursed by the
Fund for expenses assumed during  a fiscal year prior to  the end of such  year.
The  foregoing  policy  will have  the  effect  of lowering  the  Fund's overall
expenses ratio and increasing yield to  investors when such amounts are  assumed
or  the inverse when such  amounts are reimbursed. During  the fiscal year ended
February 28, 1995, the Distributor voluntarily  limited Rule 12b-1 fees to  .28%
of  average daily  net assets,  resulting in  total operating  expenses equal to
1.76% of average daily net assets.  Absent any Rule 12b-1 fee limitation,  total
Fund  operating expenses for the fiscal year ended February 28, 1995, would have
been 1.98% of average daily net assets. The management fees for fiscal 1996  may
be  more or less than those  set forth in the table  to the extent that the Fund
outperforms or  underperforms  the  EAFE  Index.  See  "Management--  Investment
Adviser."  As a  result of the  Fund's reimbursement of  its distribution costs,
which payments are considered asset-based sales charges, long-term  shareholders
of the Fund may pay more than the economic equivalent of the maximum 6.25% front
end  sales  charge permitted  under  the rules  of  the National  Association of
Securities Dealers, Inc. For additional  information, including a more  complete
explanation  of  management  and Rule  12b-1  fees,  see "Management--Investment
Adviser" and "Distribution of Fund Shares."

                       INVESTMENT OBJECTIVE AND POLICIES
 
GENERAL
 
    The Fund's investment objective  is long-term capital appreciation.  Current
income is incidental to this objective. The Fund seeks to achieve its investment
objective  through investments  primarily (under normal  circumstances, at least
65% of its total assets) in Common Stock of companies in the Pacific Basin or in
Europe (including Eastern Europe). "Common Stock" means common stock and foreign
equity securities which are  substantially similar to common  stock in the  U.S.
and  does  not  include preferred  stock  or convertible  debt  securities (such
foreign equity securities may have  voting and distribution rights which  differ
from  those of common stock in the U.S.). The Pacific Basin is generally defined
as those  countries bordering  the Pacific  Ocean. The  Fund may  invest in  the
following  countries  within  the  region: Malaysia,  Pakistan,  Sri  Lanka, the
Philippines, Singapore,  South Korea,  Thailand,  India, Indonesia,  Hong  Kong,
Japan,  Taiwan,  Australia and  New  Zealand. In  addition,  to the  extent that
suitable investment
 
                                       5
<PAGE>
opportunities become available, the Fund may invest in any other country  within
the  region,  including,  but  not  limited  to,  China.  For  purposes  of this
Prospectus, unless  otherwise indicated,  Europe consists  of Austria,  Belgium,
Denmark,  Germany, Finland, France, Greece, the  Republic of Ireland, Italy, the
Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, Turkey and the United
Kingdom (together,  "Western Europe"),  plus Albania,  Bulgaria, the  Czech  and
Slovak  Republics, Hungary, Poland, Romania, the  successor states to the former
Yugoslavia, and the Commonwealth of  Independent States (formerly, the Union  of
Soviet  Socialist  Republics) (together,  "Eastern  Europe"). As  the securities
markets of additional continental European countries develop, such countries may
be considered part of the Fund's definition of Europe and appropriate  countries
for  investment by the  Fund. For a  discussion of the  economies of the Pacific
Basin and Europe, see "Investment Objective, Policies and
Restrictions--Investment Background" in the Statement of Additional Information.
 
    As of March 31,  1995, approximately 64% of  the Fund's investments were  in
companies  in the Pacific Basin (including  Japan) and approximately 26% were in
companies in Europe. While the Fund has no specific policy or restriction on the
allocation of its funds  between Europe and the  Pacific Basin, the Adviser  and
the  Sub-Adviser (collectively, "Management") believe that the opportunities for
long-term capital appreciation in  the Pacific Basin  are generally superior  to
those  presently available in  the economically more mature  areas of the world.
The relative emphasis of  the Fund's investments between  the Pacific Basin  and
Europe  may  change  over  time  to  the  extent  Management  identifies greater
investment opportunities in Europe as a result of more attractive values, recent
developments in  Eastern  Europe,  the  removal  of  most  intra-European  trade
barriers as a result of the adoption of the Single European Act in 1992 or other
factors.  In normal market conditions, the  Fund's investments will be allocated
among at least three different countries in the Pacific Basin and/or Europe. For
additional  information  regarding  the  allocation  of  Fund  investments,  see
"Investment Objective, Policies and Restrictions--Investment
Background--Allocation  of Investments Between the  Pacific Basin and Europe" in
the Statement of Additional Information.
 
    A company is considered to be in the Pacific Basin or in Europe, as the case
may be, if (a) it  is organized under the laws  of a country within the  Pacific
Basin  or in  Europe (including  the United  Kingdom); (b)  at least  50% of its
assets are located in the  Pacific Basin or in Europe;  (c) it derives at  least
50% of its total revenues from goods produced, sales made, services performed or
investment in companies in the Pacific Basin or in Europe; or (d) its securities
are  traded  principally  on stock  exchanges  in  a Pacific  Basin  or European
country. The Fund's definition  of companies in the  Pacific Basin or in  Europe
may  include companies  that reflect  economic and  market forces  applicable to
other regions as well as the  Pacific Basin or Europe. Nevertheless,  Management
believes that investment in such companies is appropriate in light of the Fund's
investment  objective  because  Management selects  among  such  companies those
which, in its  view, have sufficiently  strong exposure to  economic and  market
forces  in the Pacific  Basin or in  Europe, as the  case may be,  such that the
value of the securities of such companies will tend to reflect Pacific Basin  or
European  developments to a  greater extent than  developments in other regions.
With respect to the investment by the Fund in companies that receive 50% or more
of their revenues from investments in companies located in the Pacific Basin  or
Europe   (e.g.,  investment  companies  and  trusts),  the  Fund  believes  that
securities of  such companies  will  similarly reflect  the development  of  the
region  in which it invests and, in addition, the purchase of such securities is
currently one  of  the few  mechanisms  through which  the  Fund may  invest  in
securities of South Korean, Taiwanese and Indian companies.
 
    Up  to 25% of the Fund's total assets  may be invested in other areas of the
world to the extent significant opportunities for long-term capital appreciation
outside of the  Pacific Basin and  Europe become available.  The Fund  currently
invests a portion of its assets in certain countries in Latin America, including
Mexico,  Brazil, Argentina,  Chile, Peru,  Venezuela, Colombia  and Ecuador. The
Fund may invest in other Latin  American countries as opportunities develop.  As
of  March 31, 1995, approximately 2% of the Fund's investments were in companies
in Latin America. The Fund does not invest in Common Stock of U.S. companies. No
assurance can be given that the Fund's investment objective will be achieved.
 
    The investment objective of the Fund  is not fundamental and may be  changed
without  shareholder approval.  If there  is a  change in  investment objective,
shareholders should consider whether the Fund remains an appropriate  investment
in light of their then current financial position and needs.

TYPES OF SECURITIES IN WHICH THE FUND MAY INVEST
 
    The  Fund invests primarily in  Common Stock. In addition,  up to 10% of the
Fund's assets may be invested in rights, options or warrants to purchase  Common
Stock. In addition to investing directly in Common Stock, the Fund may invest in
American Depository Receipts ("ADRs") and European Depository Receipts ("EDRs").
Generally,  ADRs  in  registered  form are  U.S.  dollar  denominated securities
designed for use  in the  U.S. securities markets,  which represent  and may  be
converted  into the  underlying foreign security.  EDRs are  typically issued in
bearer form and  are designed for  use in the  European securities markets.  The
Fund  also may  purchase shares of  investment companies or  trusts which invest
principally in  securities  in which  the  Fund  is authorized  to  invest.  The
purchase  of investment  company stock  currently is  one of  the few mechanisms
through which  the  Fund  may  invest in  securities  of  Indian  and  Taiwanese
companies.  For a discussion of the  risks of investing in investment companies,
see "Risk Factors-- Investment and Repatriation Restrictions."
 
    For temporary defensive purposes, the Fund may invest without limitation  in
U.S.  dollar denominated or foreign currency denominated cash or in high quality
debt securities with remaining maturities of  one year or less. Such  securities
may  include commercial paper, certificates of deposit, bankers' acceptances and
securities issued  by  the U.S.  or  a  foreign government,  their  agencies  or
instrumentalities.  All  securities  in  which the  Fund  invests  for defensive
purposes (other than securities  issued or guaranteed by  the U.S. or a  foreign
government,  their agencies or instrumentalities) must  be rated AA or better by
Standard & Poor's Corporation or be  of comparable quality as determined by  the
Adviser.  For an  explanation of  ratings, see  Appendix A  to the  Statement of
Additional Information.
 
                           SPECIAL INVESTMENT METHODS
 
    The  following  discussion  describes  some  of  the  investment  management
practices  that the Fund  may employ from  time to time  to facilitate portfolio
management and mitigate risk.
 
FOREIGN CURRENCY TRANSACTIONS
 
    The Fund engages in  currency exchange transactions  in connection with  the
purchase  and  sale  of  its  investments.  Currency  exchange  transactions are
necessary to enable  the Fund to  purchase securities denominated  in a  foreign
currency and to convert interest and dividend payments or sales proceeds paid in
a  foreign currency into U.S. dollars or into another currency. In addition, the
Fund may engage in  forward foreign currency  exchange transactions and  foreign
currency  futures and options  transactions to protect  against uncertainty with
respect to future currency exchange rates. Forward currency exchange and futures
and options transactions are used only for hedging and not for speculation.  The
Fund  conducts its currency exchange transactions  either on a spot (cash) basis
at the rate prevailing in the currency exchange market or through entering  into
forward or futures contracts to purchase or sell foreign currencies.
 
    The  Fund may engage in "transaction hedging" to protect against a change in
the foreign currency exchange rate between the date on which the Fund  contracts
to  purchase or sell  the security and the  settlement date or  to "lock in" the
U.S. dollar  equivalent (or  other  foreign currency  equivalent to  the  extent
needed  for purposes of purchasing securities) of a dividend or interest payment
in a foreign currency. For that purpose, the Fund may purchase or sell a foreign
currency on a spot  (or cash) basis  at the prevailing  spot rate in  connection
with  the settlement of transactions in portfolio securities denominated in that
foreign currency.
 
    If conditions warrant, the Fund may also enter into contracts to purchase or
sell foreign currencies at a future  date ("forward contracts") and purchase  or
sell  foreign currency futures  contracts as a hedge  against changes in foreign
currency exchange rates  between the  trade and settlement  dates on  particular
transactions  and not for speculation. A  foreign currency forward contract is a
negotiated agreement to exchange currency  at a future time  at a rate or  rates
that  may  be higher  or  lower than  the  spot rate.  Foreign  currency futures
contracts  are   standardized   exchange-traded  contracts   and   have   margin
requirements.
 
    For transaction hedging purposes, the Fund may also purchase exchange-listed
and  over-the-counter call and put options on foreign currency futures contracts
and on foreign currencies. A put option on a
 
                                       7
<PAGE>
futures contract gives  the Fund the  right to  assume a short  position in  the
futures  contract until expiration of the option. A put option on currency gives
the Fund the right to sell a currency at an exercise price until the  expiration
of  the option. A call option on a  futures contract gives the Fund the right to
assume a  long position  in the  futures contract  until the  expiration of  the
option.  A  call option  on  currency gives  the Fund  the  right to  purchase a
currency at the exercise price until the expiration of the option.
 
    The Fund may engage  in "position hedging" to  protect against a decline  in
the  value relative to the U.S. dollar  of the currencies in which its portfolio
securities are denominated or  quoted (or an increase  in the value of  currency
for  securities which the Fund  intends to buy, when  it holds cash reserves and
short-term investments). For position hedging purposes, the Fund may purchase or
sell foreign currency futures contracts and foreign currency forward  contracts,
and  may purchase put or call options  on foreign currency futures contracts and
in foreign currencies  on exchanges or  over-the-counter markets. In  connection
with  position hedging, the Fund may also purchase or sell foreign currency on a
spot basis.
 
    Transaction and  position  hedging  do not  eliminate  fluctuations  in  the
underlying  prices of the securities which the  Fund owns or intends to purchase
or sell. They simply establish a rate of exchange which one can achieve at  some
future  point in time. Additionally, although  these techniques tend to minimize
the risk of loss due to a decline in the value of the hedged currency, they tend
to limit any potential gain which might result from the increase in the value of
such currency. In addition, hedging transactions involve costs and may result in
losses. The Fund may write covered call options on foreign currencies to  offset
some  of  the  costs  of  hedging those  currencies.  The  Fund  will  engage in
over-the-counter transactions only when appropriate exchange-traded transactions
are unavailable and when, in the  opinion of the Adviser, the pricing  mechanism
and  liquidity  are satisfactory  and the  participants are  responsible parties
likely to meet their  contractual obligations. The Fund's  ability to engage  in
hedging  and related option  transactions may be  limited by tax considerations.
See "Taxation--Consequences of  Certain Fund  Investments" in  the Statement  of
Additional Information.
 
    For  additional  information  regarding foreign  currency  transactions, see
"Investment Objective, Policies and Restrictions--Foreign Currency Transactions"
in the Statement of Additional Information.
 
HEDGING
 
    The Fund  may  engage in  various  futures  and put  and  call  transactions
(collectively,  "Hedging  Transactions"). Hedging  Transactions  may be  used to
attempt to protect against possible declines  in the market value of the  Fund's
portfolio,  to protect the Fund's unrealized gains in the value of its portfolio
securities, to facilitate the sale of such securities for investment purposes or
to establish a position in the securities markets as a temporary substitute  for
purchasing  particular securities. Any or all of these techniques may be used at
any time.  There  is no  overall  limitation on  the  percentage of  the  Fund's
portfolio  securities which  may be  subject to  a hedge  position. There  is no
particular strategy that requires use of one technique rather than another.  Use
of  any  Hedging Transaction  is a  function of  market conditions.  The Hedging
Transactions that  the Fund  may  use are  described below.  Additional  Hedging
Transactions  may be used by the Fund in the future as they are developed to the
extent deemed appropriate by the Board of Directors of the Fund.
 
    OPTIONS ON  SECURITIES.   In seeking  to reduce  fluctuations in  net  asset
value,  the  Fund may  write  (i.e., sell),  covered  put and  call  options and
purchase put and call  options on the  securities in which  it may invest.  Such
options  are  traded  on  U.S.  and  foreign  securities  exchanges  and  in the
over-the-counter markets.
 
    A put option gives the buyer of such option, upon payment of a premium,  the
right to deliver a specified amount of a security to the writer of the option on
or  before  a fixed  date  at a  predetermined price.  A  call option  gives the
purchaser of the option, upon payment of  a premium, the right to call upon  the
writer to deliver a specified amount of a security on or before a fixed date, at
a  predetermined price. A  call option written  by the Fund  is "covered" if the
Fund owns the underlying  security covered by  the call or  has an absolute  and
immediate  right to acquire that  security without additional cash consideration
(or for  additional cash  consideration  held in  a  segregated account  by  its
custodian)  upon  conversion  or  exchange  of  other  securities  held  in  its
portfolio. A call option is  also covered if the Fund  holds a call on the  same
security and in the same principal amount as the call written where the exercise
price of the call held (a) is equal to or
 
                                       8
<PAGE>
less  than the  exercise price of  the call written  or (b) is  greater than the
exercise price of the call written if  the difference is maintained by the  Fund
in  cash and high grade liquid debt  securities in a segregated account with its
custodian. A put option written by the  Fund is "covered" if the Fund  maintains
cash  and high grade liquid  debt securities with a  value equal to the exercise
price in a segregated  account with its  custodian, or else holds  a put on  the
same  security and  in the same  principal amount  as the put  written where the
exercise price of the put held is equal to or greater than the exercise price of
the put written. The Fund will not write puts if, as a result, more than 50%  of
the  Fund's assets would be  required to be segregated.  The premium paid by the
purchaser of an option will reflect, among other things, the relationship of the
exercise price to the  market price and volatility  of the underlying  security,
the remaining term of the option, supply and demand and interest rates.
 
    In  purchasing a call option,  the Fund would be in  a position to realize a
gain if, during the option period, the price of the security increased above the
call option price by an amount in  excess of the cost of the option.  Otherwise,
it  would realize a  loss. In purchasing  a put option,  the Fund would  be in a
position to  realize a  gain if,  during the  option period,  the price  of  the
security  declined below the put option price by an amount in excess of the cost
of the option.  Otherwise, it  would realize  a loss. If  a put  or call  option
purchased  by the Fund were permitted to expire without being sold or exercised,
its premium would be lost by the Fund.
 
    If a  put option  written by  the Fund  were exercised,  the Fund  would  be
obligated  to purchase the underlying security at  the exercise price. If a call
option written by the Fund were exercised,  the Fund would be obligated to  sell
the  underlying security at the  exercise price. The risk  involved in writing a
put option  is that  there  could be  a  decrease in  the  market value  of  the
underlying  security caused by  rising interest rates or  other factors. If this
occurred, the option could be exercised  and the underlying security would  then
be  sold to the Fund at a higher price than its current value. The risk involved
in writing a call option is that there could be an increase in the market  value
of  the underlying security caused by declining interest rates or other factors.
If this occurred,  the option  could be  exercised and  the underlying  security
would  then be sold by the Fund at  a lower price than its current market value.
These risks could be reduced by entering into a closing transaction as described
in Appendix B to the Statement  of Additional Information. The Fund retains  the
premium  received from writing a put or call option whether or not the option is
exercised. See  Appendix B  to the  Statement of  Additional Information  for  a
further discussion of the use, risks and costs of option trading.
 
    The  exchanges have established position limits governing the maximum number
of options which may be written by  an investor or group of investors acting  in
concert.  Similarly, the Commodities Futures  Trading Commission and the Chicago
Board of Trade have established futures position limits for an investor or group
of investors acting in concert. (A discussion of the Fund's ability to invest in
futures contracts and options thereon is  set forth below.) The position  limits
may  restrict the Fund's  ability to purchase  or write options  on a particular
security or to enter into  futures contracts. It is  possible that the Fund  and
other clients of the Adviser, including closed-end and other open-end investment
companies  managed by the Adviser, may be  considered to be a group of investors
acting in concert. Thus, the number of options or futures transactions which the
Fund may enter into may be affected by options or futures transactions of  other
investment advisory clients of the Adviser.
 
    Over-the-counter  options are purchased or written  by the Fund in privately
negotiated transactions. Such options  are illiquid and it  may not be  possible
for  the  Fund  to  dispose of  an  option  it has  purchased  or  terminate its
obligations under an option it has written  at a time when the Adviser  believes
it would be advantageous to do so.
 
    FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS.  The Fund may enter into
contracts  for  the  purchase  or  sale for  future  delivery  of  securities or
contracts based on financial indices including any index of securities in  which
the  Fund may invest  ("futures contracts") and  may purchase and  write put and
call options to buy or sell futures contracts ("options on futures  contracts").
A "sale" of a futures contract means the acquisition of a contractual obligation
to  deliver the securities called for by the  contract at a specified price on a
specified date. The purchaser of a futures  contract on an index agrees to  take
or  make  delivery  of an  amount  of cash  equal  to the  difference  between a
specified dollar multiple of the  value of the index  on the expiration date  of
the  contract ("current contract value") and the price at which the contract was
originally
 
                                       9
<PAGE>
struck. No physical  delivery of the  securities underlying the  index is  made.
Options  on futures  contracts to be  written or  purchased by the  Fund will be
traded on exchanges  or over-the-counter. These  investment techniques are  used
only  to hedge against declines in the  value of the Fund's portfolio securities
or increases in the prices of securities which the Fund intends to purchase at a
later date. The  successful use of  such instruments relies  upon the  Adviser's
experience with respect to such instruments. Should prices move in an unexpected
manner,  the Fund may not achieve  the anticipated benefits of futures contracts
or options on futures  contracts or may  realize losses and would  thus be in  a
worse  position than  if such  strategies had  not been  used. In  addition, the
correlation between movements in  the price of futures  contracts or options  on
futures  contracts and movements in the prices  of the securities hedged or used
for cover will not  be perfect. See  Appendix B to  the Statement of  Additional
Information  for  further discussion  of  the use,  risks  and costs  of futures
contracts and options on futures contracts.
 
    Futures contracts and options on futures contracts are used only as a  hedge
and  not for speculation. In addition, the  Fund does not enter into any futures
contracts or options on futures  contracts if immediately thereafter the  amount
of initial margin deposits on all the futures contracts of the Fund and premiums
paid  on options on futures contracts would exceed 5% of the market value of the
total assets of the  Fund. This restriction  will not be  changed by the  Fund's
Board  of Directors without considering the policies and concerns of the various
applicable federal and state regulatory agencies.
 
    The Fund  limits its  activities in  options and  futures contracts  to  the
extent  necessary  to  prevent  disqualification  of  the  Fund  as  a regulated
investment company under the Internal Revenue Code. For a discussion of the  tax
treatment of futures contracts and options on futures contracts, see "Taxation--
Consequences  of  Certain  Fund  Investments"  in  the  Statement  of Additional
Information.
 
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES
 
    The Fund may purchase securities on  a "when-issued" basis and may  purchase
or  sell securities  on a  "forward commitment"  basis. The  Fund may  make such
purchases in order to lock-in the purchase price of a security which  Management
believes  will appreciate in value. There is  always the risk, however, that the
security will decrease in  value prior to its  delivery. When such  transactions
are  negotiated, the  price is  fixed at  the time  the commitment  is made, but
delivery and payment for the securities take place at a later date, which can be
a month or more after  the date of the transaction.  At the time the Fund  makes
the  commitment to  purchase securities on  a when-issued  or forward commitment
basis, it will record the transaction  and thereafter reflect the value of  such
securities  in determining its net asset value. At the time the Fund enters into
a transaction on a when-issued or forward commitment basis, a segregated account
consisting of cash or high  grade liquid debt securities  equal to the value  of
the  when-issued  or  forward  commitment  securities  will  be  established and
maintained with the custodian  and will be  marked to the  market daily. On  the
delivery  date, the Fund will meet its obligations from securities that are then
maturing or sale of the securities  held in the segregated asset account  and/or
from  then available cash flow.  If the Fund disposes of  the right to acquire a
when-issued security  prior to  its  acquisition or  disposes  of its  right  to
deliver or receive against a forward commitment, it can incur a gain or loss due
to market fluctuation.
 
    There is always a risk that the securities may not be delivered and that the
Fund may incur a loss or will have lost the opportunity to invest the amount set
aside  for such  transaction in  the segregated  asset account.  The purchase of
securities on a when-issued or forward commitment basis can result in  increased
volatility  of the  Fund's net  asset value  to the  extent the  Fund makes such
purchases while  remaining  substantially  fully invested.  Settlements  in  the
ordinary  course, which may take substantially more than three business days for
non-U.S. securities,  are not  treated by  the Fund  as when-issued  or  forward
commitment  transactions  and, accordingly,  are  not subject  to  the foregoing
limitations even though some of the risks described above may be present in such
transactions.
 
REPURCHASE AGREEMENTS
 
    The  Fund  may  enter,   without  limitation,  into  repurchase   agreements
pertaining  to the securities in which it  may invest with securities dealers or
member banks of the Federal Reserve System. A repurchase agreement arises when a
buyer such as the Fund purchases a security and simultaneously agrees to  resell
it  to the vendor at an agreed-upon future  date, normally one day or a few days
later. The resale price is greater than the purchase price, reflecting an agreed
upon  interest  rate   which  is   effective  for   the  period   of  time   the
 
                                       10
<PAGE>
buyer's  money is invested in  the security and which  is related to the current
market rate  rather  than  the  coupon rate  on  the  purchased  security.  Such
agreements  permit the Fund  to keep all  of its assets  at work while retaining
"overnight" flexibility in pursuit of  investments of a longer-term nature.  The
Fund  requires continual  maintenance by  its custodian  for its  account in the
Federal Reserve/Treasury Book Entry System of collateral in an amount equal  to,
or  in  excess of,  the resale  price. In  the  event a  vendor defaults  on its
repurchase obligation,  the Fund  might suffer  a loss  to the  extent that  the
proceeds  from the sale of the collateral are less than the repurchase price. In
the event of a vendor's bankruptcy, the  Fund might be delayed in, or  prevented
from,  selling  the  collateral for  the  Fund's  benefit. The  Fund's  Board of
Directors has established  procedures, which  are periodically  reviewed by  the
Board,  pursuant to which  the Adviser will monitor  the creditworthiness of the
dealers  and  banks  with  which  the  Fund  enters  into  repurchase  agreement
transactions.
 
LENDING OF SECURITIES
 
    In order to facilitate achievement of its investment objective, the Fund may
from  time to time  lend securities from  its portfolio to  brokers, dealers and
financial institutions  and receive  collateral  in the  form  of cash  or  U.S.
government  securities. Securities  lending may  be used  to generate  income to
cushion the Fund against declines in stock prices without requiring the Fund  to
sell  portfolio securities which  it believes will appreciate  in value. As with
other extensions of credit, there are risks of delay in recovery or even loss of
rights in the collateral should the borrower of the securities fail financially.
However, the Fund will enter into  loan arrangements only with brokers,  dealers
or  financial  institutions which  the Adviser  has determined  are creditworthy
under guidelines  established by  the Fund's  Board of  Directors. In  addition,
collateral  for such loans must be maintained at all times in an amount equal to
at least 100% of  the current market value  of the loaned securities  (including
interest  on  the  loaned  securities).  The  interest  accruing  on  the loaned
securities will be paid to the Fund and the Fund will have the right, on demand,
to call back the loaned securities. The Fund may pay fees to arrange the  loans.
The Fund does not lend portfolio securities in excess of 30% of the value of its
total  assets  (including such  loans),  nor does  the  Fund lend  its portfolio
securities to any officer,  director, employee or affiliate  of the Fund or  the
Adviser or Sub-Adviser.
 
ILLIQUID SECURITIES
 
    As  a fundamental investment restriction that may not be changed without the
approval of a majority of the Fund's shares, the Fund will not invest more  than
15%  of its net assets in illiquid securities. A security is considered illiquid
if it cannot be  sold in the  ordinary course of business  within seven days  at
approximately  the price at which it is  valued. Illiquid securities may offer a
higher yield than securities which are more readily marketable, but they may not
always be marketable on advantageous terms.
 
    The sale of  illiquid securities  often requires  more time  and results  in
higher  brokerage charges  or dealer discounts  and other  selling expenses than
does the  sale  of  securities  eligible  for  trading  on  national  securities
exchanges  or in the over-the-counter markets. The Fund may be restricted in its
ability to sell such securities at a time when the Adviser or Sub-Adviser  deems
it  advisable to do so.  In addition, in order  to meet redemption requests, the
Fund may have to sell other assets,  rather than such illiquid securities, at  a
time which is not advantageous.
 
    "Restricted securities" are securities which were originally sold in private
placements  and which have not been registered  under the Securities Act of 1933
(the "1933 Act"). Such securities generally have been considered illiquid, since
they may  be resold  only subject  to statutory  restrictions and  delays or  if
registered  under the  1933 Act. In  1990, however, the  Securities and Exchange
Commission adopted Rule 144A  under the 1933 Act,  which provides a safe  harbor
exemption  from the  registration requirements  of the  1933 Act  for resales of
restricted securities to  "qualified institutional  buyers," as  defined in  the
rule.  The result  of this rule  has been the  development of a  more liquid and
efficient  institutional  resale   market  for   restricted  securities.   Thus,
restricted securities are no longer necessarily illiquid. The Fund may therefore
invest  in Rule  144A securities and  treat them  as liquid when  they have been
determined to be  liquid by  the Board  of Directors of  the Company  or by  the
Adviser  or Sub-Adviser subject  to the oversight of  and pursuant to procedures
adopted by  the Board  of  Directors. See  "Investment Objective,  Policies  and
Restrictions--
 
                                       11
<PAGE>
Illiquid  Securities"  in  the  Statement  of  Additional  Information.  Similar
determinations may be made with respect  to commercial paper issued in  reliance
on  the so-called "private placement"  exemption from registration under Section
4(2) of the 1933 Act.
 
BORROWING
 
    The Fund  may  borrow money  only  from  banks for  temporary  or  emergency
purposes  in  an amount  up to  10% of  the  value of  the Fund's  total assets,
provided that reverse  repurchase agreements entered  into by the  Fund are  not
subject  to such limitation. Reverse repurchase agreements are subject, however,
to the asset coverage  requirements of the Investment  Company Act of 1940  (the
"1940  Act") and  to certain segregated  account requirements. The  Fund has not
entered into  reverse repurchase  agreements  in the  past  and has  no  current
intention  of  entering  into such  agreements  in the  future.  See "Investment
Objective, Policies  and  Restrictions--Reverse Repurchase  Agreements"  in  the
Statement of Additional Information. Interest paid by the Fund on borrowed funds
will decrease the net earnings of the Fund. The Fund will not purchase portfolio
securities   while  outstanding   borrowings  (other   than  reverse  repurchase
agreements) exceed 5%  of the value  of the  Fund's total assets.  The Fund  may
mortgage,  pledge or  hypothecate its  assets only  to secure  such temporary or
emergency borrowing. The policies  set forth in  this paragraph are  fundamental
and may not be changed without the approval of a majority of the Fund's shares.
 
PORTFOLIO TURNOVER
 
    The  Fund  intends  to acquire  and  hold securities  for  long-term capital
appreciation and normally does not intend to trade in securities for  short-term
gains; however, securities may be purchased and sold at such times as Management
deems  to be in the best interests of  the Fund and its shareholders. The method
of calculating  portfolio  turnover  rate  is set  forth  in  the  Statement  of
Additional    Information    under   "Investment    Objective,    Policies   and
Restrictions--Portfolio Turnover." Portfolio turnover rates for the Fund are set
forth in "Financial Highlights."
 
INVESTMENT RESTRICTIONS
 
    The Fund  has  adopted  certain fundamental  and  nonfundamental  investment
restrictions  in  addition  to  those set  forth  above.  Fundamental investment
restrictions which may not be  changed without shareholder approval include  the
following: (1) With respect to 75% of its total assets, the Fund will not invest
more  than 5% of the  value of its total  assets in any one  issuer, or own more
than 10%  of  the  outstanding  voting securities  of  any  one  issuer.  (These
restrictions  do  not  apply to  securities  issued  or guaranteed  by  the U.S.
government or  any agency  or  instrumentality thereof.  For purposes  of  these
restrictions, the government of any country (other than the U.S.), including its
governmental  subdivisions, is  each considered a  single issuer.)  (2) The Fund
will not  invest 25%  or more  of the  value of  its total  assets in  the  same
industry. (This restriction does not apply to securities issued or guaranteed by
the  U.S.  government or  its agencies  or  instrumentalities.) In  addition, as
nonfundamental investment restrictions which may be changed at any time  without
shareholder approval, the Fund will not invest more than 5% of its net assets in
warrants or more than 5% of its total assets in the securities of issuers which,
with  their predecessors,  have a  record of  less than  three years' continuous
operation. A  list  of  the Fund's  fundamental  and  nonfundamental  investment
restrictions is set forth in the Statement of Additional Information.
 
                                  RISK FACTORS
 
    Investment  in  foreign  securities requires  consideration  of  factors not
typically associated  with  investment  in securities  of  U.S.  issuers.  Those
include the following:
 
    CURRENCY  FLUCTUATIONS.    The  value  of  the  Fund's  portfolio securities
computed in U.S. dollars will vary with increases and decreases in the  exchange
rate  between the currencies in which the Fund has invested and the U.S. dollar.
A decline in the value of any  particular currency against the U.S. dollar  will
cause  a decline in the  U.S. dollar value of  the Fund's holdings of securities
denominated in such currency  and, therefore, will cause  an overall decline  in
the  Fund's net asset value and net investment income and capital gains, if any,
to be distributed in U.S. dollars to shareholders by the Fund.
 
                                       12
<PAGE>
    The rate  of  exchange between  the  U.S.  dollar and  other  currencies  is
determined  by several factors,  including the supply  and demand for particular
currencies, central bank efforts to support particular currencies, the  movement
of  interest rates,  the price of  oil, the  pace of activity  in the industrial
countries, including  the  United  States,  and  other  economic  and  financial
conditions affecting the world economy.
 
    POLITICAL AND ECONOMIC RISKS.  Investing in securities of non-U.S. companies
may  entail  additional  risks. Nationalization,  expropriation  or confiscatory
taxation, currency blockage,  political changes,  government regulation,  social
instability  or diplomatic developments could affect  adversely the economy of a
country or the Fund's investment in such country. The Fund may also be adversely
affected by exchange control regulations.
 
    Certain additional  risks are  involved in  investing in  the securities  of
Eastern  European issuers. Although the  Fund has the ability  to invest in such
securities, because of  current political instability  and military conflict  in
Eastern  Europe, the Fund does  not currently hold any  such securities and does
not intend to  purchase any  such securities  until a  more favorable  political
climate exists.
 
    Upon the accession to power of Communist regimes approximately 50 years ago,
the  governments of a number of  Eastern European countries expropriated a large
amount of property. The claims of many property owners against those governments
were never finally settled. There can be no assurance that any Fund  investments
in  Eastern Europe  would not  also be  expropriated, nationalized  or otherwise
confiscated. In  the  event  of such  expropriation,  nationalization  or  other
confiscation, the Fund could lose its entire investment in the country involved.
In  addition,  any change  in  the leadership  or  policies of  Eastern European
countries, or any change  in the leadership or  policies of the Commonwealth  of
Independent  States  (formerly, the  Union of  Soviet Socialist  Republics) that
exercises a significant influence over  those countries, may halt the  expansion
of  or reverse the  liberalization of foreign  investment policies now occurring
and adversely affect existing investment opportunities.
 
    Most Eastern  European countries  have had  a centrally  planned,  socialist
economy since shortly after World War II. The governments of a number of Eastern
European  countries currently are implementing reforms directed at political and
economic liberalization, including efforts to decentralize the economic decision
making process and move towards a market economy. There can be no assurance that
these reforms  will continue  or, if  continued, will  achieve their  goals.  In
addition,  favorable economic developments in Eastern Europe may not continue or
may be reversed by  unanticipated political events  that could adversely  affect
the Fund if it were invested in the securities of Eastern European issuers.
 
    Investing  in the  securities of  Eastern European  issuers involves certain
considerations not usually associated with investing in securities of issuers in
more developed  capital markets  such as  the United  States, Japan  or  Western
Europe,  including (a)  political and  economic considerations,  such as greater
risks of  expropriation,  confiscatory  taxation and  nationalization  and  less
social,  political and  economic stability;  (b) the  small current  size of the
markets for  such securities  and the  currently low  or nonexistent  volume  of
trading,  resulting in  lack of liquidity  and in price  volatility; (c) certain
national policies  which  may  restrict  the  Fund's  investment  opportunities,
including,   without  limitation,  restrictions  on   investing  in  issuers  or
industries deemed sensitive to relevant national interests; and (d) the  absence
of  developed  legal structures  governing  private or  foreign  investments and
private property.
 
    CORPORATE  DISCLOSURE  STANDARDS  AND  GOVERNMENTAL  REGULATION.    Non-U.S.
companies  are  not  generally  subject  to  uniform  accounting,  auditing  and
financial reporting standards or to other regulatory requirements comparable  to
those   applicable  to  U.S.  companies.  Thus,  there  may  be  less  available
information concerning non-U.S. issuers of securities  held by the Fund than  is
available concerning U.S. companies.
 
    Applicable  accounting and  financial reporting standards  in Eastern Europe
may be substantially different  from U.S. accounting  standards and, in  certain
Eastern   European   countries,   no   reporting   standards   currently  exist.
Consequently, substantially less  information on Eastern  European companies  is
available  to  investors  and  the  information that  is  available  may  not be
conceptually comparable to, or prepared on  the same basis as that available  in
more  developed  capital markets,  which  may make  it  difficult to  assess the
financial status of particular companies. However, in order to become attractive
to Western
 
                                       13
<PAGE>
international investors such as  the Fund, some  Eastern European companies  may
submit  to reviews  of their  financial condition  conducted in  accordance with
accounting standards employed in Western European countries. Management believes
that such  information,  together  with  the  application  of  other  analytical
techniques,  can  provide an  adequate basis  on which  to assess  the financial
viability of such companies.
 
    MARKET CHARACTERISTICS.  Securities of  many non-U.S. companies may be  less
liquid  and  their  prices  more volatile  than  securities  of  comparable U.S.
companies. In addition, securities of companies traded in many countries outside
the U.S., particularly those of emerging countries in the Pacific Basin, may  be
subject  to further risks due to the inexperience of local brokers and financial
institutions  in  less  developed  markets,  the  possibility  of  permanent  or
temporary  termination of  trading, and  greater spreads  between bid  and asked
prices for securities. Non-U.S. stock exchanges and brokers are subject to  less
governmental  supervision and  regulation than  in the  U.S. and  non-U.S. stock
exchange transactions  are  usually  subject to  fixed  commissions,  which  are
generally  higher than negotiated commissions on U.S. transactions. In addition,
there may in  certain instances be  delays in the  settlement of non-U.S.  stock
exchange transactions.
 
    INVESTMENT  AND REPATRIATION RESTRICTIONS.  Several  of the countries in the
Pacific Basin  and  certain European  countries  restrict, to  varying  degrees,
foreign   investments  in  their  securities  markets.  Government  and  private
restrictions take a variety of forms, including (a) limitations on the amount of
funds that may  be introduced into  or repatriated from  the country  (including
limitations  on  repatriation  of  investment  income  and  capital  gains); (b)
prohibitions or  substantial  restrictions  on  foreign  investment  in  certain
industries  or market sectors,  such as defense,  energy and transportation; (c)
restrictions (whether  contained in  the  charter of  an individual  company  or
mandated  by the government) on the percentage  of securities of a single issuer
which may  be owned  by a  foreign investor;  (d) limitations  on the  types  of
securities  which a  foreign investor  may purchase;  and (e)  restrictions on a
foreign investor's  right  to  invest  in companies  whose  securities  are  not
publicly traded. In some circumstances, these restrictions may limit or preclude
investment  in  certain  countries or  may  increase  the cost  of  investing in
securities of particular companies.
 
    The governments of  certain Eastern  European countries may  require that  a
governmental  or  quasi-governmental authority  act as  custodian of  the Fund's
assets invested in such countries. These authorities may not be qualified to act
as foreign custodians under the 1940 Act and, as a result, the Fund will not  be
able  to invest in these  countries in the absence  of exemptive relief from the
Securities and  Exchange  Commission. In  addition,  the risk  of  loss  through
government confiscation may be increased in such countries.
 
    The  Fund may  make direct  investments in Taiwan  if it  adheres to certain
government restrictions  or may  invest in  Taiwanese stocks  quoted  elsewhere.
However,  the Fund currently intends to invest in Taiwan through the purchase of
shares of  investment funds  organized  under the  laws  of Taiwan  and  through
Euromarket  Instruments. The Fund  currently may not  make direct investments in
India. However,  the laws  regarding  investments in  India by  foreigners  have
recently changed and the Fund will most likely apply to the authorities in India
for  permission to  invest directly  in that country.  The return  on the Fund's
investments in investment companies will  be reduced by the operating  expenses,
including  investment advisory and  administrative fees, of  such companies. The
Fund's investment in an investment company may require the payment of a  premium
above  the net asset  value of the  investment company's shares,  and the market
price of the investment company thereafter may decline without any change in the
value of the investment company's assets. The Fund, however, will not invest  in
any  investment  company  or trust  unless  it  is believed  that  the potential
benefits of such investment  are sufficient to warrant  the payment of any  such
premium. Under the 1940 Act, the Fund may not invest more than 10% of its assets
in investment companies or more than 5% of its total assets in the securities of
any  one investment  company, nor  may it  own more  than 3%  of the outstanding
voting securities of any such company.
 
    FOREIGN TAXES.  The Fund's interest and dividend income from foreign issuers
may be subject to non-U.S.  withholding taxes. The Fund  also may be subject  to
taxes  on trading profits in some countries.  In addition, many of the countries
in the Pacific Basin have a transfer  or stamp duties tax on certain  securities
transactions.  The imposition of these taxes will  increase the cost to the Fund
of investing in  any country imposing  such taxes. For  U.S. tax purposes,  U.S.
shareholders  may be  entitled to  a credit  or deduction  to the  extent of any
foreign income taxes paid by the Fund. See "Tax Status."

                                   MANAGEMENT
 
BOARD OF DIRECTORS
 
    The Board of Directors  of Piper Global has  the primary responsibility  for
overseeing the overall management of Piper Global and electing its officers.
 
INVESTMENT ADVISER
 
    Piper  Capital  Management Incorporated  (the  "Adviser") has  been retained
under an Investment Advisory and Management Agreement (the "Advisory Agreement")
with Piper  Global  to act  as  the Fund's  investment  adviser subject  to  the
authority of the Board of Directors.
 
    In  addition to acting as  the investment adviser for  the Fund, the Adviser
serves as  investment adviser  to  a number  of  other open-end  and  closed-end
investment companies and to various other concerns, including pension and profit
sharing  funds,  corporate funds  and  individuals. As  of  March 31,  1995, the
Adviser rendered  investment advice  regarding  approximately $10.2  billion  of
assets.  The Adviser  is a  wholly owned  subsidiary of  Piper Jaffray Companies
Inc., a publicly held corporation which  is engaged through its subsidiaries  in
various  aspects of the financial services  industry. The address of the Adviser
is  Piper  Jaffray  Tower,  222  South  Ninth  Street,  Minneapolis,   Minnesota
55402-3804.
 
    The  Adviser supervises, directs  and monitors the day  to day operations of
the Fund  in  accordance with  the  Fund's investment  objective,  policies  and
restrictions, as well as the implementation of investment programs formulated by
the  Sub-Adviser. The  Adviser is responsible  for investing the  portion of the
Fund's portfolio maintained in cash and short-term high quality debt securities.
The Adviser reviews investment and allocation determinations of the Sub-Adviser.
In addition, the Sub-Adviser must obtain the Adviser's approval prior to (a) any
investment of the assets of the Fund in any country outside of the Pacific Basin
or Europe,  and (b)  any investment  by the  Sub-Adviser which  would result  in
reallocation  of  in  excess of  5%  of  the Fund's  total  assets.  The Adviser
determines the  broker-dealers which  are eligible  to execute  transactions  on
behalf  of the  Fund. The  Adviser furnishes  at its  own expense  all necessary
administrative services,  office space,  equipment  and clerical  personnel  for
providing the foregoing services. In addition, the Adviser pays the salaries and
fees  of all  officers and  directors of  the Fund  who are  affiliated with the
Adviser. The Adviser  is liable to  the Fund for  losses resulting from  willful
misconduct,  bad faith or gross  negligence in the performance  of its duties or
from its reckless disregard of its duties under the Advisory Agreement.
 
    Under the Advisory Agreement, the Fund pays the Adviser a monthly management
fee. The fee is paid at an annual  rate of 1.00% on average daily net assets  up
to  $100 million, .875% on net assets over  $100 million and up to $200 million,
and .75% on net assets  over $200 million (the "Basic  Fee"), and is subject  to
adjustment  as  described below.  The adjustment  is  based upon  the investment
performance of  the Fund  in relation  to the  investment record  of the  Morgan
Stanley  Capital International EAFE-SM- Index (the  "EAFE Index"). The Basic Fee
is higher than fees paid by most other investment companies.
 
    Adjustments to the Basic Fee are made by comparison of the Fund's investment
performance for the  applicable period with  the investment record  of the  EAFE
Index.  The Basic Fee for each month may be increased or decreased by up to .25%
(on an annualized basis) of the  Fund's average daily net assets depending  upon
the  extent (as set forth below) by which the Fund's performance varies from the
EAFE Index over the applicable  performance period. For purposes of  calculation
of  the performance adjustment, average daily net assets are equal to the Fund's
average daily net  assets during the  month for which  the calculation is  being
made.

    The Basic  Fee, plus  or  minus the  performance adjustments  calculated  as
described  herein,  is  paid monthly.  The  applicable performance  period  is a
rolling 12-month period consisting  of the most recent  calendar month plus  the
immediately preceding 11 months.
 
    In  calculating the investment performance of  the Fund as compared with the
investment record of the  EAFE Index, dividends and  other distributions of  the
Fund  and  dividends  and other  distributions  made with  respect  to component
securities of the EAFE Index during the performance period are treated as having
been reinvested. The investment performance of the Fund is calculated based upon
the total return of the  Fund for the applicable  period, which consists of  the
total net asset value of the Fund at the end of the applicable period, including
reinvestment  of dividends  and distributions, less  the net asset  value of the
Fund at the commencement of the applicable period divided by the net asset value
of the  Fund  at the  commencement  of the  applicable  period. Fractions  of  a
percentage  point are rounded  to the nearest  whole point (to  the higher whole
point if exactly one-half).
 
    The EAFE Index is a market  capitalization weighted index containing (as  of
March  31, 1995)  1,113 companies representing  approximately 60%  of the market
capitalization of  each  of  the following  20  countries:  Australia,  Austria,
Belgium,  Denmark, Finland, France,  Germany, Hong Kong,  Ireland, Italy, Japan,
The Netherlands,  New  Zealand,  Norway,  Singapore,  Malaysia,  Spain,  Sweden,
Switzerland  and the  United Kingdom.  The EAFE Index  is an  unmanaged index of
common stocks, whereas the  Fund, under normal circumstances,  may invest up  to
35%  of  its assets  in securities  other than  common stock.  Additionally, the
largest percentages of the EAFE Index are currently represented by the  Japanese
and United Kingdom markets, which currently represent approximately 44% and 16%,
respectively,  of the  EAFE Index.  Consequently, the  extent to  which the EAFE
Index increases or decreases in any  one year will be affected significantly  by
the  performance of these markets. The  Fund currently has approximately 33% and
9%, respectively, of its total assets invested in Japan and the United  Kingdom.
Because  the Fund's weighting in these two markets is not as significant as that
of the  EAFE Index,  the performance  of the  other markets  in which  the  Fund
invests,  as compared to that  of the Japanese and  United Kingdom markets, will
affect to a significant degree whether the Fund outperforms or underperforms the
EAFE Index.

Investors  Fiduciary Trust Company ("IFTC"), 127 West Tenth Street, Kansas City,

                                       17
<PAGE>
shares may  also  be  considered a  factor  if  the Adviser  or  Sub-Adviser  is
satisfied  that the Fund would receive from that broker the most favorable price
and execution then available for  a transaction. Portfolio transactions for  the
Fund  may  be  effected through  the  Distributor  on a  securities  exchange in
compliance with  Section  17(e) of  the  1940  Act. For  more  information,  see
"Portfolio  Transactions  and  Allocation  of  Brokerage"  in  the  Statement of
Additional Information.
 
                          DISTRIBUTION OF FUND SHARES
 
    Piper Jaffray acts as the principal distributor of the Fund's shares.  Piper
Global  has adopted a Distribution  Plan (the "Plan") as  required by Rule 12b-1
under the 1940 Act. Under the Plan, the Distributor is entitled to reimbursement
each month for its actual expenses incurred in connection with servicing of  the
Fund's shareholder accounts and in connection with distribution related services
provided  with respect to the Fund, in an amount not to exceed, on an annualized
basis, .50% of the average daily net assets of the Fund.
 
    The Distributor is reimbursed  under the Plan for  its expenses incurred  in
connection  with the sale  of Fund shares ("Distribution  Expenses") and for its
costs in connection with the ongoing servicing and/or maintenance of shareholder
accounts ("Shareholder  Servicing Costs").  Of  the .50%  of average  daily  net
assets  reimbursable under the Plan, .25% may be reimbursed to cover Shareholder
Servicing Costs and .25% may be  reimbursed to cover Distribution Expenses.  The
Distributor  has voluntarily  agreed to limit  reimbursements under  the Plan to
 .32% of the Fund's average daily net  assets. This limitation may be revised  or
terminated  at  any  time  after  fiscal 1996  year  end.  The  Adviser  and the
Distributor, out of their own assets,  may pay for certain expenses incurred  in
connection  with  the distribution  of shares  of the  Fund. In  particular, the
Adviser may make  payments out  of its own  assets to  Piper Jaffray  investment
executives  and other broker dealers in connection with their sales of shares of
the Fund.  See "How  to Purchase  Shares--Purchase Price."  Further  information
regarding the Plan is contained in the Statement of Additional Information.
 
    The Distributor's Shareholder Servicing Costs include payments to investment
executives  of the Distributor and broker-dealers  which have entered into sales
agreements  with  the  Distributor.  If  shares  of  the  Fund  are  sold  by  a
representative  of a broker-dealer other than the Distributor, the broker-dealer
is paid .30% of the average daily net assets of the Fund attributable to  shares
sold by the broker-dealer's representative. If shares of the Fund are sold by an
investment  executive of the Distributor, compensation is paid to the investment
executive in the manner set  forth in a written agreement,  in an amount not  to
exceed  .30% of the average daily net  assets of the Fund attributable to shares
sold by the investment executive. Of such  payments, an amount equal to .25%  of
average  daily net assets of the Fund is considered a Shareholder Servicing Cost
under the  Plan  and the  remainder  is considered  ongoing  sales  compensation
reimbursable as a Distribution Expense under the Plan.

    This table sets forth total  sales charges or underwriting commissions.  The
Distributor  may  reallow up  to the  entire sales  charge to  broker-dealers in
connection with their sales  of shares. These broker-dealers  may, by virtue  of
such reallowance, be deemed to be "underwriters" under the 1933 Act.
 
    FUND  SHARES ARE BEING OFFERED TO THE  PUBLIC WITHOUT AN INITIAL OR DEFERRED
SALES CHARGE THROUGH  JUNE 30,  1995. The  Distributor will  pay its  investment
executives  and other broker-dealers selling Fund shares a fee equal to 2.00% of
the net asset value of any shares  sold during this period. These payments  will
be  an expense of the Distributor; they will not be reimbursed by the Fund under
its Rule 12b-1 Plan.
 
    The Distributor will make certain payments to its investment executives  and
to  other  broker-dealers in  connection with  their sales  of Fund  shares. See
"Distribution of  Fund  Shares," above.  In  addition, the  Distributor  or  the
Adviser,  at  their own  expense, provide  promotional incentives  to investment
executives of the Distributor  and to broker-dealers  who have sales  agreements
with  the Distributor in connection  with sales of shares  of the Fund and other
mutual funds  for  which  the  Adviser  acts  as  investment  adviser.  In  some
instances,  these incentives  may be made  available only  to certain investment
executives or broker-dealers who  have sold or may  sell significant amounts  of
such  shares. The incentives may include  payment for travel expenses, including
lodging at luxury resorts, incurred in connection with sales seminars.

sales charge is waived. However, the  Distributor, in its discretion, may pay  a
fee  out of its own assets to its investment executives and other broker-dealers
in connection with purchases by employee benefit plans on which no sales  charge
is  imposed. Please  see the  Special Purchase  Plans section  of "Reducing Your
Sales Charge."

                           REDUCING YOUR SALES CHARGE
 
    You may qualify for a  reduced sales charge through  one or more of  several
plans.  You must notify your Piper Jaffray investment executive or broker-dealer
at the time of purchase to take advantage of these plans.
 
AGGREGATION
 
    Front-end  or  initial  sales  charges  may  be  reduced  or  eliminated  by
aggregating  your purchase with purchases  of certain related personal accounts.
In addition,  purchases made  by members  of certain  organized groups  will  be
aggregated  for  purposes  of  determining  sales  charges.  Sales  charges  are
calculated by adding the dollar amount of your current purchase to the higher of
the cost or current value of shares of  any Piper fund sold with a sales  charge
that  are currently held by you and your related accounts or by other members of
your group.
 
    QUALIFIED GROUPS.    You  may  group purchases  in  the  following  personal
accounts together:
 
    - Your individual account.
 
    - Your spouse's account.
 
    - Your children's accounts (if they are under the age of 21).
 
    - Your  employee  benefit plan  accounts if  they  are exclusively  for your
      benefit. This includes accounts such  as IRAs, individual 403(b) plans  or
      single-participant Keogh-type plans.
 
    - A  single trust estate or single fiduciary  account if you are the trustee
      or fiduciary.
 
    Additionally, purchases made by members  of any organized group meeting  the
requirements  listed below may  be aggregated for  purposes of determining sales
charges:
 
    - The group has been in existence for more than six months;
 
    - It is not organized for the  purpose of buying redeemable securities of  a
      registered investment company; and

    - Purchases  must be  made through  a central  administration, or  through a
      single dealer, or by other means that result in economy of sales effort or
      expense.
 
    An organized  group does  not  include a  group  of individuals  whose  sole
organizational  connection is participation as credit card holders of a company,
policyholders  of  an  insurance  company,   customers  of  either  a  bank   or
broker-dealer or clients of an investment adviser.
 
RIGHT OF ACCUMULATION
 
    Sales  charges for purchases of Fund shares into Piper Jaffray accounts will
be automatically calculated  taking into account  the dollar amount  of any  new
purchases  along with the higher  of current value or  cost of shares previously
purchased in the  Piper funds  that were  sold with  a sales  charge. For  other
broker-dealer  accounts, you should notify your investment executive at the time
of purchase of additional Piper fund shares you may own.
 
LETTER OF INTENT
 
    Your sales charge may be reduced by signing a non-binding Letter of  Intent.
This  Letter of Intent will  state your intention to  invest $100,000 or more in
any of  the  Piper funds  sold  with a  sales  charge over  a  13-month  period,
beginning  not earlier than 90  days prior to the date  you sign the Letter. You
will pay the  lower sales  charge applicable  to the  total amount  you plan  to
invest  over the 13-month period. Part of your  shares will be held in escrow to
cover additional sales charges that may be due if you do not invest the  planned
amount.  Please  see  "Purchase  of  Shares"  in  the  Statement  of  Additional
Information for  more details.  You can  contact your  Piper Jaffray  investment
executive or other broker-dealer for an application.

      qualified  cash  or  deferred  arrangement  under  Section  401(k)  of the
      Internal Revenue Code of 1986, as amended (the "Code") (a "401(k)  Plan").
      In the event a 401(k) Plan of an employer has purchased shares in the Fund
      or  in any other  mutual fund managed  by the Adviser  (other than a money
      market fund) during any calendar quarter, any other employee benefit  plan
      of such employer that is a qualified plan under Section 401(a) of the Code
      also may purchase shares of the Fund during such quarter without incurring
      a sales charge.
 
    - Custodial   accounts  under   Section  403(b)   of  the   Code  (known  as
      tax-sheltered annuities) also may buy shares of the Fund without incurring
      a sales charge.
 
                              HOW TO REDEEM SHARES
 
NORMAL REDEMPTION
 
    You may redeem  all or a  portion of your  shares on any  day that the  Fund
values  its  shares.  (Please refer  to  "Valuation  of Shares"  below  for more
information.) Your  shares  will  be  redeemed  at  the  net  asset  value  next
calculated  after the receipt  of your instructions  in good form  by your Piper
Jaffray investment executive or other broker-dealer as explained below.
 
    PIPER JAFFRAY INC.  ACCOUNTS.  To  redeem your shares,  please contact  your
Piper Jaffray investment executive with an oral request to redeem your shares.
 
    OTHER BROKER-DEALER ACCOUNTS.  To redeem your shares, you may either contact
your  broker-dealer with an oral  request or send a  written request directly to
the Fund's transfer agent, IFTC. This request should contain: the dollar  amount
or number of shares to be redeemed, your Fund account number and either a social
security  or tax  identification number  (as applicable).  You should  sign your
request in exactly the same way the account is registered. If there is more than
one owner of the shares, all owners must sign. A signature guarantee is required
for redemptions over  $25,000. Please contact  IFTC or refer  to "Redemption  of
Shares" in the Statement of Additional Information for more details.
 
CONTINGENT DEFERRED SALES CHARGE
 
    If  you invest  $500,000 or more  and, as  a result, pay  no front-end sales
charge, you may incur a contingent deferred sales charge if you redeem within 24
months. This charge will be equal to 1% of the lesser of the net asset value  of
the  shares at the  time of purchase or  at the time  of redemption. This charge
does not apply to amounts representing an  increase in the value of Fund  shares
due  to  capital  appreciation or  to  shares acquired  through  reinvestment of
dividend or  capital gain  distributions. In  determining whether  a  contingent
deferred  sales charge is payable,  shares that are not  subject to any deferred
sales charge will be redeemed first, and  other shares will then be redeemed  in
the order purchased.
 
    LETTER  OF INTENT.  In  the case of a Letter  of Intent, the 24-month period
begins on the date the Letter of Intent is completed.

                         SHAREHOLDER GUIDE TO INVESTING
 
    SPECIAL PURCHASE PLANS.   If you  purchased your shares  through one of  the
plans  described above under  "Special Purchase Plans,"  the contingent deferred
sales charge will be waived. In  addition, the contingent deferred sales  charge
will be waived in the event of:
 
    - The  death or disability (as  defined in Section 72(m)(7)  of the Code) of
      the shareholder. (This waiver will be  applied to shares held at the  time
      of  death  or  the  initial  determination  of  disability  of  either  an
      individual shareholder or one who owns  the shares as a joint tenant  with
      the right of survivorship or as a tenant in common.)
 
    - A  lump sum  distribution from  an employee  benefit plan  qualified under
      Section 401(a) of the Code, an individual retirement account under Section
      408(a) of the  Code or a  simplified employee pension  plan under  Section
      408(k) of the Code.
 
    - Systematic withdrawals from any such plan or account if the shareholder is
      at least 59 1/2 years old.
 
    - A  tax-free return of the excess  contribution to an individual retirement
      account under Section 408(a) of the Code.
 
    - Involuntary redemptions  effected  pursuant  to  the  right  to  liquidate
      shareholder  accounts having  an aggregate  net asset  value of  less than
      $200.
 
    EXCHANGES.  If you exchange your shares, no contingent deferred sales charge
will be imposed. However, the charge  will apply if you subsequently redeem  the
new shares within 24 months of the original purchase.
 
    REINSTATEMENT  PRIVILEGE.  If  you elect to  use the Reinstatement Privilege
(please see "Shareholder Services" below), any contingent deferred sales  charge
you  paid  will  be  credited  to  your  account  (proportional  to  the  amount
reinvested). Please see "Redemption  of Shares" in  the Statement of  Additional
Information for more details.
 
PAYMENT OF REDEMPTION PROCEEDS
 
    After  your shares  have been redeemed,  the cash proceeds  will normally be
sent to you or your broker-dealer within five business days (three business days
after June 3, 1995). In no event will payment be made more than seven days after
receipt of your order  in good form.  However, payment may  be postponed or  the
right   of  redemption  suspended  for  more   than  seven  days  under  unusual
circumstances, such as when trading  is not taking place  on the New York  Stock
Exchange. Payment of redemption proceeds may also be delayed if the shares to be
redeemed  were purchased by a check drawn on a bank which is not a member of the
Federal Reserve  System,  until  such  check  has  cleared  the  banking  system
(normally up to 15 days from the purchase date).
 
INVOLUNTARY REDEMPTION
 
    The  Fund reserves the right  to redeem your account at  any time if the net
asset value of the  account falls below  $200 as the result  of a redemption  or
exchange  request. You will be notified in  writing prior to any such redemption
and will be allowed 30 days to make additional investments before the redemption
is processed.
 
                              SHAREHOLDER SERVICES
 
AUTOMATIC MONTHLY INVESTMENT PROGRAM
 
    You may arrange to make additional automated purchases of shares of the Fund
or certain other  mutual funds  managed by  the Adviser.  You can  automatically
transfer  $100  or more  per month  from your  bank, savings  and loan  or other
financial institution to purchase  additional shares. In  addition, if you  hold
your  shares in a Piper Jaffray account  you may arrange to make such additional
purchases by having $25 or

                         SHAREHOLDER GUIDE TO INVESTING
more automatically transferred  each month  from any  of the  money market  fund
series  of  Piper  Funds.  You  should  contact  your  Piper  Jaffray investment
executive or IFTC to obtain authorization forms or for additional information.
 
REINSTATEMENT PRIVILEGE
 
    If you have redeemed shares of the Fund, you may be eligible to reinvest  in
shares of any fund managed by the Adviser without payment of an additional sales
charge.  The reinvestment request must be made within 30 days of the redemption.
This privilege is subject to the eligibility of share purchases in your state as
well as the minimum  investment requirements and any  other applicable terms  in
the prospectus of the fund being acquired.
 
EXCHANGE PRIVILEGE
 
    If  your investment  goals change,  you may prefer  a fund  with a different
objective. If you are considering an  exchange into another mutual fund  managed
by  the  Adviser,  you  should carefully  read  the  appropriate  prospectus for
additional information about  that fund.  A prospectus may  be obtained  through
your  Piper Jaffray investment executive, your broker-dealer or the Distributor.
To exchange your shares, please contact your Piper Jaffray investment executive,
your broker-dealer or IFTC.
 
    You may exchange your shares for shares of any other mutual fund managed  by
the  Adviser that  is open to  new investors.  All exchanges are  subject to the
eligibility of share purchases in your  state as well as the minimum  investment
requirements  and any other applicable terms in the prospectus of the fund being
acquired. Exchanges are  made on  the basis  of net  asset values  of the  funds
involved,  except that investors exchanging into a fund which has a higher sales
charge must pay the difference.
 
    You may make four  exchanges per year without  payment of a service  charge.
Thereafter,  you  will pay  a  $5 service  charge  for each  exchange.  The Fund
reserves the  right to  change or  discontinue the  exchange privilege,  or  any
aspect of the privilege, upon 60 days' written notice.
 
TELEPHONE TRANSACTION PRIVILEGES
 
    PIPER  JAFFRAY INC. ACCOUNTS.   If you  hold your shares  in a Piper Jaffray
account, you may telephone your investment executive to execute any  transaction
or to apply for many shareholder services. In some cases, you may be required to
complete a written application.
 
    OTHER  BROKER-DEALER ACCOUNTS.  If  you hold your shares  in an account with
your broker-dealer  or  at  IFTC,  you may  authorize  telephone  privileges  by
completing  the  Account  Application  and Services  Form.  Please  contact your
broker-dealer or IFTC (800-874-6025) for an application or for more details. The
Fund will employ reasonable procedures to  confirm that a telephonic request  is
genuine,  including requiring that payment be made only to the address of record
or the bank account designated on the Account Application and Services Form  and
requiring  certain means of telephonic identification.  If the Fund follows such
procedures, it will  not be  liable for following  instructions communicated  by
telephone that it reasonably believes to be genuine. If the Fund does not employ
such  procedures,  it  may be  liable  for  any losses  due  to  unauthorized or
fraudulent telephone instructions.
 
DIRECTED DIVIDENDS
 
    You may  direct  income dividends  and  capital gains  distributions  to  be
invested  in any other  mutual fund managed  by the Adviser  (other than a money
market fund) that is offered in your state. This investment will be made at  net
asset  value. It will not be subject  to a minimum investment amount except that
you must hold shares in such fund (including the shares being acquired with  the
dividend  or distribution) with  a value at  least equal to  such fund's minimum
initial investment amount.

SYSTEMATIC WITHDRAWAL PLAN
 
    If your  account  has  a value  of  $5,000  or more,  you  may  establish  a
Systematic Withdrawal Plan. This plan will allow you to receive regular periodic
payments  by redeeming as  many shares from  your account as  necessary. As with
other redemptions,  a redemption  to make  a withdrawal  is a  sale for  federal
income  tax purposes. Payments made under a Systematic Withdrawal Plan cannot be
considered as actual yield or income since part of the payments may be a  return
of capital.
 
    A  request to  establish a Systematic  Withdrawal Plan must  be submitted in
writing to your Piper Jaffray investment executive or other broker-dealer. There
are no service charges for maintenance; the minimum amount that you may withdraw
each period is $100. You will be  required to have any income dividends and  any
capital  gains distributions reinvested. You may choose to have withdrawals made
monthly,  quarterly  or  semi-annually.   Please  contact  your  Piper   Jaffray
investment executive, other broker-dealer or IFTC for more information.
 
    You  should be aware that  additional investments in an  account that has an
active Systematic Withdrawal Plan  may be inadvisable due  to sales charges  and
tax  liabilities.  As a  result,  you will  not  be allowed  to  make additional
investments of less than $5,000 or three times the annual withdrawals while  you
have the plan in effect. Please refer to "Redemption of Shares" in the Statement
of Additional Information for additional details.
 
ACCOUNT PROTECTION
 
    If  you purchased your shares of the Fund through a Piper Jaffray investment
executive, you may choose from several account options. Your investments in  the
Fund  held in a Piper  Jaffray account (except for  non-"PAT" accounts) would be
protected up  to  $25  million.  Investments held  in  non-"PAT"  Piper  Jaffray
accounts are protected up to $2.5 million. In each case, the Securities Investor
Protection  Corporation ("SPIC") provides $500,000 of protection; the additional
coverage is provided  by The Aetna  Casualty & Surety  Company. This  protection
does not cover any declines in the net asset value of Fund shares.
 
CONFIRMATION OF TRANSACTIONS AND REPORTING OF OTHER INFORMATION
 
    Each  time there  is a  transaction involving  your Fund  shares, such  as a
purchase, redemption or dividend reinvestment,  you will receive a  confirmation
statement  describing that  activity. This information  will be  provided to you
from either Piper  Jaffray, your broker-dealer  or IFTC. In  addition, you  will
receive  various IRS forms after the first  of each year detailing important tax
information. The Fund is required to supply annual and semi-annual reports  that
list securities held by the Fund and include the current financial statements of
the Fund.
 
    HOUSEHOLDING.   If  you have multiple  accounts with Piper  Jaffray, you may
receive some of the above information  in combined mailings. This will not  only
help  to reduce  Fund expenses,  it will help  the environment  by saving paper.
Please contact your Piper Jaffray investment executive for more information.
 
                          DIVIDENDS AND DISTRIBUTIONS
 
    Dividends from  net  investment income  and  distributions of  net  realized
capital gains, if any, will be payable to Fund shareholders on an annual basis.
 
    BUYING  A DIVIDEND.  On the record date for a distribution, the Fund's share
price is reduced  by the  amount of  the distribution.  If you  buy shares  just
before  the record date ("buying  a dividend"), you will  pay the full price for
the shares  and  then  receive  a  portion  of  the  price  back  as  a  taxable
distribution.
 
    DISTRIBUTION  OPTIONS.  All net investment income dividends and net realized
capital gains distributions for the Fund generally will be payable in additional
shares of the Fund at  net asset value ("Reinvestment  Option"). If you wish  to
receive  your  distributions  in  cash,  you  must  notify  your  Piper  Jaffray
investment executive or  other broker-dealer.  You may elect  either to  receive
income dividends in cash

and  capital gains distributions in  additional shares of the  Fund at net asset
value ("Split Option"), or  to receive both income  dividends and capital  gains
distributions  in cash ("Cash Option"). You may also direct income dividends and
capital gains distributions to be invested in another mutual fund managed by the
Adviser. See  "Shareholder  Services--Directed  Dividends"  above.  The  taxable
status  of  income  dividends  and/or net  capital  gains  distributions  is not
affected by whether they are reinvested or paid in cash.
 
                              VALUATION OF SHARES
 
    The Fund  computes its  net  asset value  on each  day  the New  York  Stock
Exchange  (the "Exchange") is open  for business. The calculation  is made as of
the regular close of the Exchange (currently 4:00 p.m. New York time) after  the
Fund  has declared any  applicable dividends. In valuing  the Fund's assets, all
securities for which market  quotations are readily  available are valued  under
normal circumstances at the last sales price prior to the time of determination,
or if no sale is reported at that time, the mean between the closing asked price
and  the closing bid price or, if no  bid and asked prices are available, at the
most recent available sales price. With respect to a security which is listed or
traded on more than  one exchange, the  Fund normally looks  to the exchange  on
which  trading is more  extensive. In instances where  market 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 investments having a maturity of 60  days or less are valued at  cost
with  any premium amortized or discount credited over the period remaining until
maturity. Options will be valued at market value or fair value, as determined in
good faith by or  under the direction  of the Board of  Directors, if no  market
exists.  Futures contracts  will be valued  at the  settlement price established
each day by the board of trade or exchange on which they are traded.  Securities
and  assets for which market quotations are  not readily available are valued at
fair value as determined in good faith by or under the direction of the Board of
Directors.
 
    Any assets or liabilities initially expressed in terms of foreign currencies
are translated into U.S. dollars by the pricing service retained by the Fund or,
to the  extent that  an exchange  rate  is not  available through  such  pricing
service,  at the mean of current bid and asked prices of such currencies against
the U.S. dollar last quoted by a major bank that is a regular participant in the
foreign exchange market.  The Fund  has been  advised that  the pricing  service
translates  foreign currencies  into U.S. dollars  on the basis  of the official
exchange rate or by taking into account the quotes provided by a number of major
banks that are regular participants in  the foreign exchange market. Trading  in
securities   on  European  and   Pacific  Basin  securities   exchanges  and  in
over-the-counter markets is normally completed well before the close of business
on each  business  day of  the  Fund. In  addition,  European or  Pacific  Basin
securities  trading generally  or in a  particular country or  countries may not
take place on all business days in New York. Furthermore, trading takes place in
various foreign markets on days which are  not business days of the Fund and  on
which  the Fund's net  asset value is  not calculated. Therefore,  the net asset
value of the Fund might be significantly affected on days when the investor  has
no  access to the Fund. The Fund calculates  net asset value per share as of the
close of the regular trading session on the Exchange. Such calculation does  not
take  place  contemporaneously  with  the determination  of  the  prices  of the
majority of  the  portfolio  securities  used in  such  calculation.  If  events
materially  affecting the value  of such securities occur  between the time when
their price  is determined  and the  time when  the Fund's  net asset  value  is
calculated,  such securities will be valued at  fair value as determined in good
faith by or under the direction of the Board of Directors.
 
                                   TAX STATUS
 
    The Fund qualified as a regulated  investment company under Subchapter M  of
the  Internal Revenue Code of 1986, as amended, during its last taxable year and
intends to qualify as a regulated investment company during the current  taxable
year.  If so qualified, the Fund will not  be liable for federal income taxes to
the extent it distributes its taxable income to shareholders.

<PAGE>
- --------------------------------------------------------------------------------
                         SHAREHOLDER GUIDE TO INVESTING
 
    Distributions by the Fund are generally taxable to the shareholders, whether
received in cash or additional shares of  the Fund (or shares of another  mutual
fund  managed by the Adviser). Distributions of net capital gains (designated as
"capital gain  dividends")  are taxable  to  shareholders as  long-term  capital
gains,  regardless of the length of time  the shareholder has held shares of the
Fund.
 
    A shareholder  will  recognize a  capital  gain or  loss  upon the  sale  or
exchange  of shares  in the  Fund if, as  is normally  the case,  the shares are
capital assets in  the shareholder's hands.  This capital gain  or loss will  be
long-term if the shares have been held for more than one year.
 
    The  Fund's investments may  be subject to taxes  in foreign countries which
would reduce the total return on such  investments. In addition, if the Fund  is
deemed to be a resident of the United Kingdom for United Kingdom tax purposes or
if  the Fund is treated as being engaged  in a trading activity through an agent
in the United Kingdom, there is a  risk that the United Kingdom will attempt  to
tax all or a portion of the Fund's gains or income. In light of the structure of
the  Fund  and  the  terms  and  conditions  of  the  Advisory  and Sub-Advisory
Agreements, the Adviser believes that any such risk is minimal.
 
    If the  Fund has  more than  50%  of its  assets invested  in the  stock  or
securities  of foreign corporations at  the end of the  Fund's taxable year, the
Fund may make an election to allow shareholders either to claim U.S. foreign tax
credits with respect to such foreign taxes paid or to deduct such amounts as  an
itemized  deduction on their tax return. In  the event such an election is made,
shareholders would have to increase their  taxable income by the amount of  such
taxes  and the  Fund would  not be able  to deduct  such taxes  in computing its
taxable income.
 
    The foregoing relates to federal income taxation as in effect as of the date
of this Prospectus.  For a more  detailed discussion of  the federal income  tax
consequences of investing in shares of the Fund, see "Taxation" in the Statement
of  Additional Information. Before  investing in the Fund,  you should check the
consequences of your local and state tax laws.
 
                            PERFORMANCE COMPARISONS
 
    Advertisements and other  sales literature  for the  Fund may  refer to  the
Fund's  "average annual  total return" and  "cumulative total  return." All such
total return quotations are based upon historical earnings and are not  intended
to  indicate  future  performance.  The  return on  and  principal  value  of an
investment in  the Fund  will  fluctuate, so  that  an investor's  shares,  when
redeemed, may be worth more or less than their original cost.
 
    Average  annual return is the average annual  compounded rate of return on a
hypothetical $1,000 investment made at  the beginning of the advertised  period.
Cumulative  total  return is  calculated  by subtracting  a  hypothetical $1,000
payment to the Fund from the redeemable value of such payment at the end of  the
advertised  period,  dividing  such  difference by  $1,000  and  multiplying the
quotient by 100. In calculating average annual and cumulative total return,  the
maximum  sales  charge  is deducted  from  the hypothetical  investment  and all
dividends and distributions are assumed to be reinvested.
 
    In addition to advertising total return, comparative performance information
may be used from time  to time in advertising  the Fund's shares including  data
from  Lipper Analytical Services, Inc. and other entities or organizations which
track the performance of  investment companies. Performance of  the Fund may  be
compared  to the  EAFE Index  and to the  performance of  International Funds as
reported by Lipper.
 
    For additional information regarding the calculation of average annual total
return and cumulative total return, see "Calculation of Performance Data" in the
Statement of Additional Information.
 
                              GENERAL INFORMATION
 
    Piper Global is authorized to issue a total of 100 billion shares of  common
stock,  with a par value of  $.01 per share. These shares  can be issued in more
than   one    class   or    series.   Each    designated   series    of    stock
 
                                       27
<PAGE>
- --------------------------------------------------------------------------------
                         SHAREHOLDER GUIDE TO INVESTING
will  represent  a  separate portfolio  of  investments, each  with  a different
investment objective. The Board of  Directors has authorized two billion  shares
to  be issued as Series A Common Shares, which are the shares of common stock of
the Fund. Currently, Series A is the only outstanding series of shares of  Piper
Global.
 
    In  addition,  the Board  of  Directors may,  without  shareholder approval,
create and issue one or  more additional classes of  shares within the Fund,  as
well  as within any series of Piper Global created in the future. All classes of
shares in the Fund would be identical except that each class of shares would  be
available  through a  different distribution  channel and  certain classes might
incur different  expenses for  the  provision of  distribution services  or  the
provision  of shareholder services or administration assistance by institutions.
Shares of each class would  share equally in the gross  income of the Fund,  but
any  variation in expenses would be charged separately against the income of the
particular class incurring such expenses. This would result in variations in net
investment income accrued and dividends  paid by and in  the net asset value  of
the  different classes of the  Fund. This ability to  create multiple classes of
shares within the Fund will allow Piper Global in the future the flexibility  to
better tailor its methods of marketing, administering and distributing shares of
the  Fund to the needs of particular  investors and to allocate expenses related
to such marketing,  administration and  distribution methods  to the  particular
classes of shareholders of the Fund incurring such expenses.
 
    All  shares, when issued, will  be fully paid and  nonassessable and will be
redeemable. All shares have equal voting rights.  They can be issued as full  or
fractional  shares. A fractional share has pro  rata the same kind of rights and
privileges as  a full  share. The  shares possess  no preemptive  or  conversion
rights.
 
    Each  share has one vote (with  proportionate voting for fractional shares).
Cumulative voting is not  authorized. This means that  the holders of more  than
50%  of the shares  voting for the election  of directors can  elect 100% of the
directors if  they choose  to do  so, and,  in such  event, the  holders of  the
remaining shares will be unable to elect any directors.
 
    On  an issue affecting only a particular  series, the shares of the affected
series vote  separately. An  example of  such an  issue would  be a  fundamental
investment  restriction  pertaining  to  only  one  series.  In  voting  on  the
Investment Advisory and Management Agreement (the "Agreement"), approval of  the
Agreement  by the shareholders  of a particular series  would make the Agreement
effective as  to  that  series whether  or  not  it had  been  approved  by  the
shareholders of any other series.
 
    If  Piper Global issues shares in  additional series, the assets received by
Piper Global for the  issue or sale  of shares of each  series, and all  income,
earnings, profits and proceeds thereof, subject only to the rights of creditors,
will  be allocated to such series, and  constitute the underlying assets of such
series. The underlying assets  of each series are  required to be segregated  on
the books of account, and are to be charged with the expenses in respect to such
series  and with a  share of the  general expenses of  Piper Global. Any general
expenses of Piper Global not readily  identifiable as belonging to a  particular
series shall be allocated among the series based upon the relative net assets of
the series at the time such expenses were accrued.
 
    The  Bylaws of Piper  Global provide that shareholder  meetings need be held
only with such frequency as required under Minnesota law. Minnesota  corporation
law requires only that the Board of Directors convene shareholders meetings when
it  deems appropriate.  In addition,  Minnesota law  provides that  if a regular
meeting of shareholders has  not been held during  the immediately preceding  15
months, a shareholder or shareholders holding 3% or more of the voting shares of
Piper  Global may  demand a  regular meeting  of shareholders  by written notice
given to the chief executive officer or chief financial officer of Piper Global.
Within 30 days after receipt of the demand, the Board of Directors shall cause a

PENDING LEGAL PROCEEDINGS
 
    Complaints  have been filed  in U.S. District Court  against the Adviser and
the Distributor relating  to several  other investment companies  for which  the
Adviser  acts as investment adviser or subadviser. These lawsuits do not involve
the Fund and the Adviser and Distributor  do not believe that the lawsuits  will
have  a  material  adverse effect  upon  their  ability to  perform  under their
agreements with the Fund. An agreement  in principle has been reached to  settle
one  such  lawsuit.  The Adviser  and  Distributor  intend to  defend  the other
lawsuits vigorously.  See  "Pending  Legal  Proceedings"  in  the  Statement  of
Additional Information.
