    NATIONAL  TAX-EXEMPT FUND  AND MINNESOTA  TAX-EXEMPT FUND  (the "Funds") are
series of Piper Funds Inc. (the "Company"), an open-end mutual fund whose shares
are currently offered in twelve series.
 
    NATIONAL TAX-EXEMPT FUND  ("National Fund") has  an investment objective  of
maximum current income that is exempt from federal income taxes, consistent with
prudent  investment risk and  preservation of capital.  During periods of normal
market conditions, National Fund will invest at  least 80% of its net assets  in
securities  that generate  interest that is  not includable in  gross income for
federal income tax purposes and is not an item of tax preference for purposes of
the federal  alternative  minimum tax.  Such  securities include,  but  are  not
limited  to, securities  of states,  territories and  possessions of  the United
States and the District  of Columbia and  their agencies, instrumentalities  and
political subdivisions, and may also include derivative tax-exempt securities.
 
    MINNESOTA  TAX-EXEMPT FUND ("Minnesota Fund") has an investment objective of
maximum current income that is exempt  from both federal and State of  Minnesota
income  taxes,  consistent  with  prudent investment  risk  and  preservation of
capital. During periods of normal market conditions, Minnesota Fund will  invest
at  least 80% of its net assets in securities that generate interest that is not
includable in federal gross income or  in State of Minnesota taxable net  income
(except  for  State of  Minnesota franchise  tax  on corporations  and financial
institutions, which is measured by income) and is not an item of tax  preference
for  purposes of the federal or State of Minnesota alternative minimum tax. Such
securities include,  but  are  not  limited  to,  securities  of  the  State  of
Minnesota,  its  agencies,  instrumentalities  and  political  subdivisions, and
certain securities of United  States territories and  possessions, and may  also
include  derivative tax-exempt securities.  At least 95%  of the exempt-interest
dividends paid by Minnesota Fund will be derived from such sources.
 
    Please remember, you could lose  money with this investment. Neither  safety
of principal nor stability of income is guaranteed.
 
    This Prospectus concisely describes the information about the Funds that you
ought  to know  before investing.  Please read  it carefully  and retain  it for
future reference.

                                  INTRODUCTION
 
    Piper  Funds  Inc.  (the  "Company") is  an  open-end  management investment
company, or mutual fund, whose shares may be issued in separate diversified  and
nondiversified series. Each series in effect represents a separate fund with its
own investment objectives and policies. This Prospectus relates to National Tax-
Exempt  Fund ("National Fund") and  Minnesota Tax-Exempt Fund ("Minnesota Fund")
(collectively,  the   "Funds"),  which   are  classified   as  diversified   and
nondiversified funds, respectively. A nondiversified fund such as Minnesota Fund
may  have a larger position in a single issuer than would be the case if it were
diversified. The share price of such a fund may therefore be subject to  greater
fluctuation  as a result of  changes in the financial  condition or the market's
assessment of an individual issuer.
 
The Investment Adviser
 
    The Company  is  managed  by  Piper  Capital  Management  Incorporated  (the
"Adviser"),  a wholly owned subsidiary of Piper Jaffray Companies Inc. Each Fund
pays the Adviser a fee for managing  its investment portfolio at an annual  rate
of  .50% on  net assets up  to $250  million. For each  Fund, the  fee is scaled
downward as net assets increase in  size above $250 million. See "Management  --
Investment Adviser."
 
The Distributor
 
    Piper  Jaffray Inc.  ("Piper Jaffray"), a  wholly owned  subsidiary of Piper
Jaffray Companies Inc. and an affiliate of the Adviser, serves as Distributor of
the Funds' shares.
 
Offering Price
 
    Shares of the Funds  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. 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.  During the  Special Offering  Period which  extends
through  December 31, 1996, shares of the  Funds are being offered to the public
without an initial sales charge. However, for any purchase that would be subject
to a sales charge outside of the Special Offering Period, the Funds will  impose
a  contingent deferred  sales charge  of 2% on  redemptions during  the first 12
months after purchase, and  1% on redemptions during  the second 12 months.  See
"How  to  Purchase  Shares --  Purchase  Price"  and "How  to  Redeem  Shares --
Contingent Deferred Sales Charge."
 
Minimum Initial and Subsequent Investments
 
    The minimum initial investment  for each 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 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. See
"Shareholder Services--Exchange Privilege."
 
Redemption Price
 
    Shares of either 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
 
                                       2
<PAGE>
without a sales charge. See "How  to Redeem Shares -- Contingent Deferred  Sales
Charge."  Each Fund reserves the right, upon  30 days' written notice, to redeem
your 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 either Fund  is subject to certain  risks, as set forth in
detail under  "Investment  Objectives  and  Policies"  and  "Special  Investment
Methods." As with other mutual funds, there can be no assurance that either Fund
will achieve its objective. Each Fund is subject to interest rate risk (the risk
that  rising interest rates will make bonds issued at lower interest rates worth
less). As a result, the value of each Fund's shares will vary. Each Fund is also
subject to credit risk  (the risk that  a bond issuer will  fail to make  timely
payments  of  interest or  principal). In  addition,  if the  bonds in  a Fund's
portfolio  contain  call  provisions  that  are  currently  exercisable,   these
securities are likely to be redeemed during a period of declining interest rates
and  the Fund most likely  will have to reinvest  the proceeds in lower yielding
securities. Each  Fund,  to  the  extent set  forth  under  "Special  Investment
Methods,"  may  engage  in  the  following  investment  practices:  the  use  of
repurchase agreements and reverse repurchase  agreements, the purchase and  sale
of securities on a when-issued or delayed delivery basis, which may increase the
volatility  of a Fund's  net asset value,  and the use  of futures contracts and
options on futures contracts for hedging  purposes. All of these techniques  may
increase  the volatility  of a  Fund's net asset  value. Each  Fund may purchase
derivative tax-exempt securities, including inverse floating obligations,  which
may  be more volatile than  traditional fixed-rate tax-exempt securities. Recent
market experience has shown that certain derivative securities may be  extremely
sensitive  to changes  in interest rates  and, as  a result, the  prices of such
securities may be highly volatile.
 
Shareholder Inquiries
 
    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
regarding the Funds should be directed to the Funds at the telephone number  set
forth on the cover page of this Prospectus.

    The  purpose  of  the  above  Fund  Expenses  table  is  to  assist  you  in
understanding the various costs  and expenses that investors  in the Funds  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 less than those shown.
 
    The  information set forth in the table is based on actual expenses incurred
by the Funds during the fiscal year  ended September 30, 1996, except that  Rule
12b-1  fees reflect a voluntary limitation by the Distributor of amounts payable
to it under each Fund's Rule 12b-1 Plan to .24% of average daily net assets  for
the  fiscal year ending  September 30, 1997. The  Distributor limited Rule 12b-1
fees to .21% of each Fund's average  daily net assets for the fiscal year  ended
September  30, 1996. Absent  such limitation, Total  Fund Operating Expenses for
National Fund and Minnesota  Fund for the fiscal  year ended September 30,  1996
would  have been 1.13% and 0.99%, respectively, of average daily net assets. The
voluntary Rule 12b-1  fee limitation may  be revised or  terminated at any  time
after  the fiscal 1997  year end. The  Adviser may or  may not assume additional
expenses of the Funds from time to time, in its discretion, while retaining  the
ability  to be reimbursed by the Funds for expenses assumed during a fiscal year
prior to the  end of such  year. The foregoing  policy will have  the effect  of
lowering  a Fund's overall expense ratio  and increasing yield to investors when
such amounts are assumed  or the inverse when  such amounts are reimbursed.  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 OBJECTIVES AND POLICIES
 
    The investment objectives listed below cannot be changed without shareholder
approval. The  investment policies  and techniques  employed in  pursuit of  the
Funds'  objectives  may be  changed  without shareholder  approval,  unless such
policy or technique is  designated as "fundamental,"  in which case  shareholder
approval is required.
 
    National  Fund has an investment objective of maximum current income that is
exempt from federal income  taxes, consistent with  prudent investment risk  and
preservation  of capital. During  periods of normal  market conditions, National
Fund will invest at  least 80% of  its net assets  in Tax-Exempt Securities  (as
defined  in the following section) the interest payable on which, in the opinion
of bond  counsel, is  not includable  in  gross income  for federal  income  tax
purposes  under existing laws and is not  an item of tax preference for purposes
of the federal  alternative minimum tax.  Such securities include,  but are  not
limited  to, securities  issued by  states, territories  and possessions  of the
United States and the District of Columbia and their agencies, instrumentalities
and political subdivisions.
 
    Minnesota Fund has an investment objective of maximum current income that is
exempt from both federal  and State of Minnesota  income taxes, consistent  with
prudent  investment risk and  preservation of capital.  During periods of normal
market conditions, Minnesota  Fund will  invest at least  80% of  its assets  in
Tax-Exempt  Securities the  interest payable  on which,  in the  opinion of bond
counsel, is not  includable in  federal gross income  or in  State of  Minnesota
taxable  net income under existing laws (except for State of Minnesota franchise
tax on corporations and financial institutions, which is measured by income) and
is not  an item  of tax  preference  for purposes  of the  federal or  State  of
Minnesota  alternative minimum tax. Such securities include, but are not limited
to, securities issued by the State of Minnesota, its agencies, instrumentalities
and political  subdivisions,  and certain  securities  issued by  United  States
territorial  possessions.  Ninety-five percent  or  more of  the exempt-interest
dividends paid  by  Minnesota Fund  will  be  derived from  interest  income  on
obligations  of  the  State  of  Minnesota  or  its  political  or  governmental
subdivisions, municipalities, governmental agencies or instrumentalities.
 
    There are risks in  any investment program, and  there is no assurance  that
the investment objective of either Fund will be achieved. The net asset value of
the  shares issued by each Fund will fluctuate with changes in the market values
of  each  Fund's  investments.  See  "Investment  Objectives  and  Policies   --
Investment Risks," below.
 
    Both  Funds intend  to emphasize  investments in  Tax-Exempt Securities with
long-term maturities. The Tax-Exempt Securities  purchased by each Fund will  be
securities  rated, at the time of purchase, within the following grades assigned
by either Moody's Investors  Services, Inc. ("Moody's") (Aaa,  Aa, A or Baa  for
long-term  bonds;  MIG-1 or  MIG-2 for  notes  and other  short-term obligations
having fixed  maturities;  VMIG-1  or  VMIG-2 for  notes  and  other  short-term
obligations  having a  demand feature;  and Prime-1  and Prime-2  for commercial
paper) or Standard & Poor's Ratings  Services ("Standard & Poor's") (AAA, AA,  A
or BBB for municipal bonds; SP-1 and SP-2 for state and municipal notes; and A-1
and A-2 for commercial paper) or will be unrated Tax-Exempt Securities which, at
the  time of purchase,  are judged by  the Adviser to  be of comparable quality.
Securities rated  Baa or  BBB have  speculative characteristics  and changes  in
economic conditions or other circumstances are more likely to lead to a weakened
capacity  to make principal and  interest payments than is  the case with higher
grade bonds. If the rating of a bond held by one of the Funds drops below Baa or
BBB, the Fund will conduct  a credit analysis of  the bond prior to  determining
whether to retain or dispose of it. In no event, however, will more than 5% of a
Fund's  net assets consist of securities that  have been down-graded to a rating
lower than BBB or Baa or, if unrated, that are no longer of a quality comparable
to at least a BBB  or Baa rating, as determined  by the Adviser. The ratings  of
Moody's and
 
                                       7
<PAGE>
Standard  & Poor's represent their opinions as  to the quality of the Tax-Exempt
Securities which they undertake to rate. It should be emphasized, however,  that
ratings  are  general, and  not  absolute, standards  of  quality. Consequently,
Tax-Exempt Securities of the  same maturity, interest rate  and rating may  have
different  yields, while Tax-Exempt Securities of the same maturity and interest
rate with different ratings  may have the  same yield. For  a discussion of  the
various  ratings assigned by Moody's and Standard & Poor's see Appendix A to the
Statement of Additional Information.
 
    Rated as  well as  unrated Tax-Exempt  Securities will  be analyzed  by  the
Adviser  on the basis of available information as to creditworthiness and with a
view to various qualitative factors  and trends affecting Tax-Exempt  Securities
generally. It should be noted, however, that the amount of information about the
financial  condition  of  an  issuer  of Tax-Exempt  Securities  may  not  be as
extensive as that which is made  available by many issuers whose securities  are
more actively traded.
 
    During  normal market conditions, each Fund may  invest up to 20% of its net
assets in taxable obligations. Additionally,  during periods of abnormal  market
conditions   when  a  defensive  investment  posture  is  warranted,  each  Fund
temporarily may invest up to 100% of its net assets in taxable obligations. Such
taxable obligations,  whether purchased  for  liquidity or  temporary  defensive
purposes,  may  include the  following: Tax-Exempt  Securities rated  within the
grades set forth  above (or  unrated and  of comparable  quality) that  generate
interest  that is an item of tax preference for purposes of the federal or State
of Minnesota alternative minimum tax; taxable municipal obligations rated within
the grades  set  forth  above  for Tax-Exempt  Securities  (or  unrated  and  of
comparable  quality); obligations of the  United States government, its agencies
or instrumentalities (such as Treasury bills, notes and bonds); corporate  bonds
rated  within the three highest  grades by either Moody's  or Standard & Poor's;
commercial paper rated within  the two highest grades  by either of such  rating
services; certificates of deposit and bankers' acceptances of domestic banks and
savings  institutions having total assets at the time of investment in excess of
$1 billion  or  certificates of  deposit  of  other domestic  banks  or  savings
institutions  which are fully insured by the  Bank Insurance Fund or the Savings
Association  Insurance  Fund  administered  by  the  Federal  Deposit  Insurance
Corporation;  and repurchase agreements with respect to any of the securities in
which the Fund may invest. The Funds may also hold their assets in cash.
 
    National Fund does not intend to invest more than 25% of its total assets in
securities of  governmental  units  located  in  any  one  state,  territory  or
possession of the United States. In addition, neither Fund will invest more than
25%  of its total assets in limited  obligation bonds payable only from revenues
derived from  facilities or  projects within  a single  industry, provided  that
bonds  that have been refunded with escrowed U.S. Government securities will not
be subject to this limitation. As to utility companies, gas, electric, water and
telephone companies will be considered as separate industries.
 
Tax-Exempt Securities
 
    Tax-Exempt Securities,  as the  term  is used  in this  prospectus,  include
Municipal  Obligations,  Derivative  Municipal Obligations  and  Municipal Lease
Obligations, as defined below.
 
    MUNICIPAL OBLIGATIONS.    Municipal  Obligations  include  debt  obligations
issued  by  states,  cities,  local  authorities,  and  possessions  and certain
territories of the United States, to  obtain funds for various public  purposes,
including  the  construction of  such  public facilities  as  airports, bridges,
highways, housing, hospitals,  mass transportation, schools,  streets and  water
and  sewer works. Other  public purposes for which  Municipal Obligations may be
issued include the refinancing of  outstanding obligations and the obtaining  of
funds  for general operating expenses and for loans to other public institutions
and facilities. In  addition, certain industrial  development, private  activity
and   pollution  control  bonds  may  be  included  within  the  term  Municipal
Obligations if the interest paid thereon qualifies as exempt from federal income
tax. Municipal
 
                                       8
<PAGE>
Obligations include long-term obligations, often called municipal bonds, as well
as short-term municipal notes and  tax-exempt commercial paper. As noted  above,
however, the Funds intend to emphasize investments in Tax-Exempt Securities with
long-term maturities.
 
    The   two  principal   classifications  of  municipal   bonds  are  "general
obligation" and "revenue"  bonds. General  obligation bonds are  secured by  the
issuer's  pledge of its full  faith, credit and taxing  power for the payment of
principal and interest. Revenue bonds are payable only from the revenues derived
from a particular facility or  class of facilities or,  in some cases, from  the
proceeds  of a special  excise tax or other  specific revenue source. Industrial
development, private  activity and  pollution control  bonds are  in most  cases
revenue bonds and do not generally constitute the pledge of the credit or taxing
power  of the  issuer of  such bonds.  There are,  of course,  variations in the
security of Municipal Obligations, both  within a particular classification  and
between classifications, depending on numerous factors.
 
    Certain  Municipal  Obligations  may  carry variable  or  floating  rates of
interest whereby the rate of  interest is not fixed  but varies with changes  in
specified  market rates or  indexes, such as  a bank prime  rate or a tax-exempt
money market index. Accordingly, the yield  on such obligations can be  expected
to fluctuate with changes in prevailing interest rates.
 
    Other  Municipal  Obligations are  zero  coupon securities,  which  are debt
obligations which do not  entitle the holder to  any periodic payments prior  to
maturity  and are issued and  traded at a discount  from their face amounts. The
discount varies  depending  on the  time  remaining until  maturity,  prevailing
interest  rates, liquidity of  the security and perceived  credit quality of the
issuer. The market prices of zero coupon securities are generally more  volatile
than  the market  prices of  securities that  pay interest  periodically and are
likely to respond  to changes  in interest  rates to  a greater  degree than  do
securities  having similar  maturities and credit  quality that  do pay periodic
interest.
 
    DERIVATIVE MUNICIPAL OBLIGATIONS.   Each  Fund may  also acquire  Derivative
Municipal Obligations, which are custodial receipts or certificates underwritten
by  securities  dealers  or banks  that  evidence ownership  of  future interest
payments, principal  payments  or both  on  certain Municipal  Obligations.  The
underwriter  of  these certificates  or  receipts typically  purchases Municipal
Obligations and deposits  the securities  in an irrevocable  trust or  custodial
account  with a custodian bank, which  then issues receipts or certificates that
evidence ownership  of the  periodic  unmatured coupon  payments and  the  final
principal  payment on the  obligations. Although under the  terms of a custodial
receipt a  Fund typically  would be  authorized to  assert its  rights  directly
against  the issuer of the underlying obligation,  the Fund could be required to
assert through  the  custodian  bank  those rights  as  may  exist  against  the
underlying  issuer.  Thus,  in the  event  the  underlying issuer  fails  to pay
principal and/or interest when  due, a Fund may  be subject to delays,  expenses
and  risks that are greater than those that would have been involved if the Fund
had purchased a direct obligation of the issuer. In addition, in the event  that
the  trust  or  custodial account  in  which  the underlying  security  has been
deposited is determined to be an  association taxable as a corporation,  instead
of  a  non-taxable entity,  it would  be subject  to state  income tax  (but not
federal income tax) on the income it earned on the underlying security, and  the
yield  on the security paid to the Fund and its shareholders would be reduced by
the amount of taxes  paid. Furthermore, amounts paid  by the trust or  custodial
account  to a Fund would lose their tax-exempt character and become taxable, for
federal and  state purposes,  in the  hands of  the Fund  and its  shareholders.
However,  custodial receipts in which the  Funds will invest will be accompanied
by a tax opinion stating that interest payable on the receipts is tax exempt. If
a Fund invests  in custodial  receipts, it  is possible  that a  portion of  the
discount  at which the Fund  purchases the receipts might  have to be accrued as
taxable income during  the period  that the Fund  holds the  receipts. See  "Tax
Status -- Federal Taxation."
 
                                       9
<PAGE>
    The  principal and interest payments on the Municipal Obligations underlying
custodial receipts may be allocated in  a number of ways. For example,  payments
may  be  allocated such  that certain  custodial receipts  may have  variable or
floating interest rates and others may be stripped securities which pay only the
principal or interest  due on  the underlying Municipal  Obligations. The  Funds
currently  do  not  invest  in "interest  only"  or  "principal  only" custodial
receipts. The  Funds may  invest  in floating  rate custodial  receipts  without
limitation. Each Fund may also invest up to 20% of its total assets in custodial
receipts which are "inverse floating obligations" (also sometimes referred to as
"residual  interest  bonds").  These  securities pay  interest  rates  that vary
inversely to changes  in the  interest rates of  specified short-term  Municipal
Obligations  or an index of short-term Municipal Obligations. The interest rates
on inverse floating obligations will typically decline as short-term  tax-exempt
market  interest  rates increase  and increase  as short-term  tax-exempt market
rates decline.  Such  securities  have  the effect  of  providing  a  degree  of
investment  leverage, since the interest rates on such securities will generally
change at  a rate  which is  a multiple  (typically two)  of the  change in  the
interest  rates of the specified short-term Municipal Obligations or index. As a
result, the market values of inverse floating obligations will generally be more
volatile  than  the  market  values  of  fixed-rate  Municipal  Obligations  and
investments  in these types  of obligations will increase  the volatility of the
net asset value of shares of the Funds.
 
    Types of Derivative Municipal Obligations  other than those described  above
can  be expected to be developed and marketed from time to time. Consistent with
their investment limitations, the Funds expect  to invest in those new types  of
Derivative  Municipal Obligations that the Adviser believes may assist the Funds
in achieving their investment objectives. Each Fund will notify its shareholders
to the extent that it intends to invest  more than 5% of its net assets in  such
obligations.
 
    MUNICIPAL  LEASE OBLIGATIONS.  Also included  within the general category of
Tax-Exempt Securities  are lease  obligations or  installment purchase  contract
obligations  and  participations therein  issued by  tax-exempt issuers  such as
state and local governments and their agencies and instrumentalities to  finance
the  acquisition of  equipment and  facilities (hereinafter  collectively called
"Municipal Lease Obligations"). Each Fund may invest  up to 20% of the value  of
its  net  assets  in  Municipal  Lease  Obligations.  Although  Municipal  Lease
Obligations do not constitute general obligations  of the issuer for which  such
issuer's  taxing power  is pledged, a  Municipal Lease  Obligation is ordinarily
backed by the issuer's covenant to budget for, appropriate and make the payments
due under the obligation. However,  certain Municipal Lease Obligations  contain
"non-appropriation"  clauses which provide that the  issuer has no obligation to
make lease or  installment purchase  payments in  future years  unless money  is
appropriated   for  such  purpose  on   a  yearly  basis.  In   the  case  of  a
"non-appropriation" lease, the Fund's ability to recover under the lease in  the
event of non-appropriation or default will be limited solely to the repossession
of  the leased property, without  recourse to the general  credit of the lessee,
and disposition  of  the  property  in the  event  of  foreclosure  might  prove
difficult.  In determining Municipal  Lease Obligations in  which the Funds will
invest, the Adviser will carefully evaluate the outstanding credit rating of the
issuer (and the  probable secondary  market acceptance of  such credit  rating).
Additionally,  the Adviser may require  that certain municipal lease obligations
be issued or backed by a letter of credit or put arrangement with an independent
financial institution.
 
Special Considerations Regarding Investments in Minnesota Tax-Exempt Securities
 
    As described herein,  except during temporary  defensive periods,  Minnesota
Fund  will  invest in  Minnesota Tax-Exempt  Securities.  The Fund  is therefore
susceptible to political,  economic or regulatory  factors affecting issuers  of
Minnesota Tax-Exempt Securities. The following information provides only a brief
summary  of the complex factors affecting  the financial situation in Minnesota.
This information  is  derived  from  sources that  are  generally  available  to
investors  and is based in  part on information obtained  from various State and
local agencies in  Minnesota. It should  be noted that  the creditworthiness  of
obligations
 
                                       10
<PAGE>
issued  by local Minnesota  issuers may be unrelated  to the creditworthiness of
obligations issued by the State of Minnesota, and that there is no obligation on
the part of the State to make payment on such local obligations in the event  of
default.  For  further  information, see  "Investment  Objectives,  Policies and
Restrictions" in the Statement of Additional Information.
 
    Minnesota's constitutionally  prescribed fiscal  period is  a biennium,  and
Minnesota  operates on a  biennial budget basis.  Legislative appropriations for
each biennium are prepared and adopted  during the final legislative session  of
the immediately preceding biennium. Prior to each fiscal year of a biennium, the
State's  Department  of  Finance allots  a  portion of  the  applicable biennial
appropriation to each agency or other entity for which an appropriation has been
made. An  agency  or  other entity  may  not  expend monies  in  excess  of  its
allotment. If revenues are insufficient to balance total available resources and
expenditures,  the State's  Commissioner of  Finance, with  the approval  of the
Governor, is required to  reduce allotments to the  extent necessary to  balance
expenditures  and forecasted available resources  for the then current biennium.
The  Governor  may  prefer  legislative   action  when  a  large  reduction   in
expenditures appears necessary, and if the State's legislature is not in session
the Governor is empowered to convene a special session.
 
    Frequently  in  recent years,  legislation  has been  required  to eliminate
projected budget deficits by raising additional revenue, reducing  expenditures,
including  aids  to political  subdivisions and  higher education,  reducing the
State's budget reserve, imposing a sales tax on purchases by local  governmental
units,  and  making other  budgetary  adjustments. The  Minnesota  Department of
Finance April 1996 Estimates  project that, under current  laws, the State  will
complete  its current biennium June  30, 1997 with a  $1 million surplus, plus a
$350 million cash  flow account  balance, plus  a $270  million budget  reserve.
Total  General Fund expenditures and transfers for the biennium are projected to
be $18.9 billion.  Planning estimates (extrapolations)  for the biennium  ending
June  30, 1999 show a General Fund deficit  of $71 million, after funding a $350
million cash flow account plus a $270 million budget reserve, if current law  is
not  changed. Accordingly, there may be additional revenue increases or spending
cuts relative  to current  law. Furthermore,  under current  law spending  caps,
State  expenditures for education finance (K-12) and corrections in the biennium
ending June 30, 1999  are not anticipated to  be sufficient to maintain  program
levels  of  the previous  biennium. The  State is  party to  a variety  of civil
actions that  could adversely  affect  the State's  General Fund.  In  addition,
substantial  portions  of  State and  local  revenues are  derived  from federal
expenditures, and  reductions in  federal aid  to the  State and  its  political
subdivisions  and  other  federal  spending cuts  may  have  substantial adverse
effects on  the  economic  and fiscal  condition  of  the State  and  its  local
governmental  units.  Risks  are  inherent  in  making  revenue  and expenditure
forecasts. Economic or fiscal conditions less favorable than those reflected  in
state  budget forecasts and  planning estimates may  create additional budgetary
pressures.
 
    State grants and aids represent a large percentage of the total revenues  of
cities,  towns, counties and school districts in Minnesota. Even with respect to
bonds that are revenue obligations of the issuer and not general obligations  of
the  State, there can be no assurance that the fiscal problems referred to above
will not adversely affect the market value or marketability of the bonds or  the
ability  of the  respective obligors  to pay  interest on  and principal  of the
bonds.
 
    Both possible future changes in federal and State income tax laws, including
rate reductions, and recent Minnesota tax legislation could adversely affect the
value and marketability of Minnesota municipal bonds that are held by the  Fund.
See "Tax Status -- Minnesota Taxation" below.
 
Investment Risks
 
    As  mutual  funds investing  in  debt securities,  each  Fund is  subject to
interest rate  risk, which  is the  potential for  a decline  in the  prices  of
fixed-income  securities  in  which  the Funds  invest  due  to  rising interest
 
                                       11
<PAGE>
rates. When interest rates rise, the prices of long-term fixed-income securities
generally fall.  Conversely,  when  interest  rates fall,  the  prices  of  such
securities generally rise. The magnitude of these fluctuations will generally be
greater  at times when  a Fund's average  maturity is longer.  Each Fund is also
subject to  credit  risk.  Credit risk,  also  known  as default  risk,  is  the
possibility  that an issuer of  a security will fail  to make timely payments of
interest or  principal. Changes  by  recognized rating  services in  the  credit
ratings  of Tax-Exempt Securities, as  well as changes in  the perception of the
ability of  an issuer  to make  payments of  interest and  principal, will  also
affect  the value of  the Funds' investments.  Changes in the  value of a Fund's
portfolio  securities  will  not  affect  interest  income  derived  from  those
securities but will affect the Fund's net asset value.
 
    The Funds are also subject to call risk. Certain Tax-Exempt Securities which
may  be held by the Funds permit the  issuer at its option to "call," or redeem,
its securities. If an issuer were to redeem Tax-Exempt Securities held by a Fund
during a  time of  declining  interest rates,  the Fund  might  not be  able  to
reinvest  the proceeds  in Tax-Exempt  Securities providing  as high  a level of
investment return as the securities redeemed.
 
    Investments in inverse floating obligations also subject the Funds to  risk.
Interest  rates  on  these  securities typically  decline  as  short-term market
interest rates  increase and  increase as  short-term market  rates decline.  As
discussed  above,  such securities  have  the effect  of  providing a  degree of
investment leverage and, as a result, the market values of such securities  will
generally  be  more volatile  than the  market  values of  fixed-rate Tax-Exempt
Securities. See "Investment Objectives and Policies -- Tax-Exempt Securities  --
Derivative Municipal Obligations."
 
    Each  Fund may  invest in  unrated Tax-Exempt  Securities determined  by the
Adviser, at the time  of investment, to  be of comparable  quality to the  rated
securities  in which the Fund invests. The Funds will be more dependent upon the
Adviser's investment analysis  of such non-rated  Tax-Exempt Securities than  in
the case of rated securities.
 
    The  Adviser believes that, in general,  the secondary market for Tax-Exempt
Securities is  less  liquid  than  that  for  taxable  fixed-income  securities.
Consequently,  the ability of a Fund to  buy and sell Tax-Exempt Securities may,
at any  particular  time and  with  respect  to any  particular  securities,  be
limited. The amount of information about the financial condition of an issuer of
Tax-Exempt  Securities may not be as extensive as information about corporations
whose securities  are  publicly traded.  Obligations  of issuers  of  Tax-Exempt
Securities may be subject to provisions of bankruptcy, insolvency and other laws
affecting  the  rights and  remedies  of creditors,  such  as the  United States
Bankruptcy Code and applicable  state laws, which could  limit the ability of  a
Fund to recover payments of principal or interest on such obligations.
 
    Minnesota  Fund is  a "nondiversified" fund  under the 1940  Act. This means
that it may invest its assets in the securities of a limited number of  issuers.
Under the Internal Revenue Code, however, the Fund generally may not invest more
than  25%  of  its assets  in  securities of  any  one issuer,  other  than U.S.
Government securities. Also with  respect to 50% of  its total assets, the  Fund
may  not invest more  than 5% of its  total assets in the  securities of any one
issuer (other than U.S. Government securities). Because of the relatively  small
number  of issuers  of Minnesota Tax-Exempt  Securities, Minnesota  Fund is more
likely to invest a higher percentage of its assets in the securities of a single
issuer or of a limited number  of issuers than a diversified investment  company
that  invests  in  a broader  range  of  securities. This  practice  involves an
increased risk of loss to the Fund if the issuers are unable to make interest or
principal payments or if the market values of such securities decline.
 
    The investment techniques  used by each  Fund also pose  certain risks.  See
"Special Investment Methods."
 
                                       12
<PAGE>
    Because of the risks associated with fixed-income investments, the Funds are
intended  to be  long-term investment vehicles  and are not  designed to provide
investors with a means of speculating on short-term interest rate movements.  No
assurance  can be  given that  the Funds will  achieve their  objectives or that
shareholders will  be  protected from  the  risk of  loss  that is  inherent  in
fixed-income investing.
 
                           SPECIAL INVESTMENT METHODS
 
Repurchase Agreements
 
    Each  Fund may enter  into repurchase agreements  with respect to securities
issued or  guaranteed  as to  payment  of principal  and  interest by  the  U.S.
Government,  its agencies or instrumentalities.  A repurchase agreement involves
the purchase by  a Fund of  securities with  the condition that  after a  stated
period  of time the original seller (a member bank of the Federal Reserve System
or  a  recognized  securities  dealer)   will  buy  back  the  same   securities
("collateral")  at a predetermined price or yield. Repurchase agreements involve
certain risks not associated with direct investments in securities. In the event
the original seller defaults on its obligation to repurchase, as a result of its
bankruptcy or otherwise, the Fund will seek to sell the collateral, which action
could involve costs or delays.  In such case, the  Fund's ability to dispose  of
the  collateral to recover  such investment may be  restricted or delayed. While
collateral will at all times be maintained in an amount equal to the  repurchase
price  under the agreement  (including accrued interest  due thereunder), to the
extent proceeds from the sale of collateral were less than the repurchase  price
a  Fund would suffer a  loss. Repurchase agreements maturing  in more than seven
days are considered illiquid and subject to each Fund's restriction on investing
in illiquid  securities.  See  "--  Illiquid  Securities"  below.  Additionally,
interest  earned by a  Fund from repurchase  agreements will not  be treated for
federal or State of  Minnesota income tax purposes  as tax-exempt interest.  For
additional   information  concerning  repurchase   agreements,  see  "Investment
Policies and Restrictions" in the Statement of Additional Information.
 
Reverse Repurchase Agreements
 
    The Funds  may engage  in  "reverse repurchase  agreements" with  banks  and
securities  dealers.  Reverse  repurchase  agreements  are  ordinary  repurchase
agreements in which  the Fund is  the seller  of, rather than  the investor  in,
securities  and agrees to repurchase them at  an agreed upon time and price. Use
of a reverse repurchase agreement may be preferable to a regular sale and  later
repurchase  of  the  securities  because  it  avoids  certain  market  risks and
transaction costs. Because certain of the incidents of ownership of the security
are retained by the Fund, reverse repurchase agreements are considered a form of
borrowing by the  Fund from the  buyer, collateralized by  the security. At  the
time  a  Fund  enters  into  a  reverse  repurchase  agreement,  cash  or liquid
securities having a value sufficient to  make payments for the securities to  be
repurchased  will be segregated, and will be maintained throughout the period of
the obligation.  Reverse  repurchase  agreements  may be  used  as  a  means  of
borrowing  for investment purposes. This speculative technique is referred to as
leveraging. Leveraging  may exaggerate  the effect  on net  asset value  of  any
increase  or decrease in the market value  of a Fund's portfolio. Money borrowed
for leveraging will be subject to interest costs which may not be deductible for
tax purposes and which could possibly exceed interest income earned by the  Fund
on  the investment of such borrowed money. No  more than 25% of the total assets
of either Fund will at any time be subject to reverse repurchase agreements.
 
Borrowing
 
    Each Fund may borrow money from banks for temporary or emergency purposes in
an amount up to 10% of the value of its total assets. Interest paid by a Fund on
borrowed funds would decrease the net  earnings of that Fund. Neither Fund  will
purchase  portfolio securities while outstanding  borrowings (other than reverse
repurchase agreements) exceed 5% of the  value of the Fund's total assets.  Each
Fund  may mortgage, pledge or hypothecate its  assets in an amount not exceeding
10% of the value of its total assets to
 
                                       13
<PAGE>
secure temporary  or  emergency  borrowing.  The  policies  set  forth  in  this
paragraph  are fundamental  and may  not be  changed without  the approval  of a
majority of a Fund's shares.
 
When-Issued Securities
 
    Each Fund may purchase  and sell Tax-Exempt Securities  on a when-issued  or
delayed delivery basis. When-issued and delayed delivery transactions arise when
securities  are purchased or  sold with payment and  delivery beyond the regular
settlement date. (When-issued transactions  normally settle within 30-45  days.)
On  such transactions the payment obligation and  the interest rate are fixed at
the time  the  buyer  enters  into  the  commitment.  Pending  delivery  of  the
securities,  each  Fund  maintains  in  a  segregated  account  cash  or  liquid
securities in  an  amount  sufficient  to meet  its  purchase  commitments.  The
commitment  to purchase  securities on a  when-issued or  delayed delivery basis
involves an element of risk  because the value of  the securities is subject  to
market fluctuation. No interest accrues to the purchaser prior to the settlement
of  the  transaction  and  at the  time  of  delivery the  market  value  of the
securities may be  less than  cost. Purchasing  securities on  a when-issued  or
delayed delivery basis involves the additional risk that the return available in
the  market when the delivery  takes place will be  higher than that obtained in
the transaction itself. These  risks could result in  increased volatility of  a
Fund's  net asset value  to the extent  that the Fund  purchases securities on a
when-issued or  delayed  delivery  basis  while  remaining  substantially  fully
invested.  Although  the  Funds  will only  make  commitments  to  purchase such
obligations with the intention of  actually acquiring the securities, the  Funds
may  each sell these  securities before the  settlement date. If  a Fund sells a
when-issued or delayed delivery security before the settlement date, any gain or
loss would not be exempt from federal  or Minnesota income tax. For purposes  of
the  Funds' investment  policies, the purchase  of securities  with a settlement
date occurring on the Public Securities Association approved settlement date  is
considered a normal delivery and not a when-issued or delayed delivery purchase.
For   additional  information   concerning  when-issued   and  delayed  delivery
transactions, see  "Investment Objectives,  Policies  and Restrictions"  in  the
Statement of Additional Information.
 
Puts
 
    Each  Fund may purchase Tax-Exempt Securities which provide for the right to
resell them to the issuer, a bank or a broker-dealer at a specified price within
a specified period of time prior to the maturity date of such obligations.  Such
a  right to resell, which is commonly known as a "put," may be sold, transferred
or assigned only with the underlying security or securities. Each Fund may pay a
higher price for a  Tax-Exempt Security with  a put than would  be paid for  the
same  security  without  a put.  The  primary purpose  of  purchasing Tax-Exempt
Securities with  puts  is  to permit  each  Fund  to be  as  fully  invested  as
practicable  in Tax-Exempt Securities while at  the same time providing the Fund
with appropriate  liquidity. For  additional  information concerning  puts,  see
"Investment   Objectives,  Policies  and  Restrictions"   in  the  Statement  of
Additional Information.
 
Futures Contracts and Options on Futures Contracts
 
    The Funds may purchase and sell  municipal bond index futures contracts  and
interest  rate futures contracts.  The futures contracts in  which the Funds may
invest have been developed  by and are traded  on national commodity  exchanges.
Municipal  bond index futures contracts are  based upon The Bond Buyer Municipal
Bond Index,  an  index comprised  of  tax-exempt bonds  rated  A- or  higher  by
Standard  & Poor's or  A or higher  by Moody's, with  remaining maturities of 19
years or more.  A buyer entering  into a municipal  bond index futures  contract
will,  on a specified future date, pay or  receive a final cash payment equal to
the difference between  the actual value  of the index  on the last  day of  the
contract  and the value  of the index  established by the  contract. An interest
rate futures contract is an agreement to purchase or sell an agreed upon  amount
of debt securities at a set price for delivery on a future date.
 
                                       14
<PAGE>
    The purpose of the acquisition or sale of a futures contract by a Fund is to
hedge against fluctuations in the value of its portfolio without actually buying
or  selling securities. For example, if interest rates are expected to increase,
a Fund might sell futures contracts.  If interest rates did increase, the  value
of  the securities in the  Fund's portfolio would decline,  but the value of the
Fund's futures contracts would increase at approximately the same rate,  thereby
keeping  the net asset value of the Fund  from declining as much as it otherwise
would have. If, on the  other hand, the Fund  held cash reserves and  short-term
investments pending anticipated investment in long-term obligations and interest
rates  were  expected  to decline,  the  Fund  might purchase  interest  rate or
municipal bond index  futures contracts.  Since the behavior  of such  contracts
would  generally be similar to that of long-term securities, the Fund could take
advantage of the anticipated rise in  the value of long-term securities  without
actually  buying them until  the market had  stabilized. At that  time, the Fund
could accept delivery under the futures contracts or the futures contracts could
be liquidated  and the  Fund's reserves  could  then be  used to  buy  long-term
securities  in the cash market. The Funds  will engage in such transactions only
for hedging purposes, on  either an asset-based or  a liability-based basis,  in
each  case in accordance with the rules and regulations of the Commodity Futures
Trading Commission. See Appendix B to the Statement of Additional Information.
 
    The Funds  may  also purchase  and  sell put  and  call options  on  futures
contracts  and enter into  closing transactions with respect  to such options to
terminate existing  positions.  The  Funds  may  use  such  options  on  futures
contracts  in connection with their hedging strategies in lieu of purchasing and
selling the underlying futures contracts.
 
    There are risks in using futures contracts and options on futures  contracts
as  hedging  devices.  The primary  risks  associated  with the  use  of futures
contracts and  options thereon  are  (a) the  prices  of futures  contracts  and
options  may not  correlate perfectly  with the  market value  of the securities
subject to the hedge and (b) the possible lack of a liquid secondary market  for
a futures contract and the resulting inability to close a futures position prior
to  its maturity date.  With respect to municipal  bond index futures contracts,
the degree of correlation will depend, among other things, upon the  differences
between  the  municipal securities  being  hedged and  the  municipal securities
underlying the municipal bond index futures contract. The risk that a Fund  will
be  unable to close  out a futures  position will be  minimized by entering into
such transactions on  a national exchange  with an active  and liquid  secondary
market.
 
    Additional  information  with respect  to futures  contracts and  options on
futures contracts is  set forth  in Appendix B  to the  Statement of  Additional
Information.
 
Other Hedging Instruments
 
    The  Funds expect that new types  of futures contracts, options thereon, and
put and call options on municipal securities and indexes may be developed in the
future that will further enable the Funds to hedge against changes in the  value
of  their  portfolio securities.  As new  types of  hedging futures  and options
instruments are developed and offered to investors, the Adviser will, consistent
with each  Fund's  investment  objective, policies  and  quality  standards,  be
permitted to invest in such new types of instruments, provided that any decision
to so invest will be followed by supplementation of this Prospectus.
 
Illiquid Securities
 
    As  a nonfundamental investment restriction which may be changed at any time
without shareholder approval, each Fund may invest up to 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.
 
                                       15
<PAGE>
    The  sale of  illiquid securities  often requires  more time  and results in
higher brokerage charges or  dealer discounts than does  the sale of  securities
eligible for trading on national securities exchanges or in the over-the-counter
markets.  A Fund may be  restricted in its ability to  sell such securities at a
time when the Adviser deems it advisable to do so. In addition, in order to meet
redemption requests, a  Fund may  have to sell  other assets,  rather than  such
illiquid or restricted 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 SEC 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. Neither Fund is subject to any limitation on its ability to invest  in
securities  simply  because  such  securities  are  restricted.  The  Funds  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  subject to the oversight  of and pursuant to  procedures adopted by the
Board of Directors.  See "Investment  Objectives, Policies  and Restrictions  --
Illiquid  Securities"  in  the  Statement  of  Additional  Information.  Similar
determinations may be made with respect  to commercial paper issued in  reliance
upon the so-called "private placement" exemption from registration under Section
4(2) of the 1933 Act and with respect to municipal lease obligations.
 
Portfolio Turnover
 
    While  it is not the policy of  either Fund to trade actively for short-term
profits, each Fund will  dispose of securities without  regard to the time  they
have been held when such action appears advisable to the Adviser. In the case of
each Fund, frequent changes may result in higher transaction and other costs for
the  Fund. The method of calculating portfolio turnover rate is set forth in the
Statement of Additional Information  under "Investment Objectives, Policies  and
Restrictions  -- Portfolio Turnover." Portfolio turnover rates for the Funds are
set forth in "Financial Highlights."
 
Investment Restrictions
 
    Each Fund has adopted certain  investment restrictions in addition to  those
set   forth  above.  Included   among  these  restrictions   are  the  following
nonfundamental investment restrictions which may be changed at any time  without
shareholder  approval: (1) Neither  Fund will invest  more than 5%  of its total
assets in  the securities  of other  investment companies  except as  part of  a
merger,  consolidation or  acquisition of assets.  (2) Neither  Fund will invest
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. (3)
Neither Fund will invest more than 5% of its total assets in foreign securities.
A list of each Fund's fundamental and nonfundamental investment restrictions  is
set forth in the Statement of Additional Information.
 
    Except   for  each  Fund's  policy  regarding  borrowing,  if  a  percentage
restriction set  forth  under  "Investment Objectives  and  Policies"  or  under
"Special Investment Methods" is adhered to at the time of an investment, a later
increase  or decrease in  percentage resulting from changes  in values or assets
will not constitute a violation of such restriction.

                                   MANAGEMENT
 
Board of Directors
 
    The  Company's  Board  of  Directors  has  the  primary  responsibility  for
overseeing the overall management of the Company and electing its officers.
 
Investment Adviser
 
    Piper  Capital Management Incorporated has been retained under an Investment
Advisory and  Management  Agreement  with  the Company  to  act  as  the  Funds'
investment adviser subject to the authority of the Board of Directors.
 
    In  addition to acting as the investment adviser for the other series of the
Company, the Adviser furnishes investment advice  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
November 1, 1996, the Adviser rendered investment advice regarding approximately
$9  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.
 
    The  Adviser furnishes each  Fund with investment  advice and supervises the
management and investment programs  of the Funds. The  Adviser furnishes at  its
own  expense all necessary administrative  services, office space, equipment and
clerical personnel for servicing the investments of the Funds. The Adviser  also
provides  investment advisory facilities and executive and supervisory personnel
for managing the  investments and  effecting the portfolio  transactions of  the
Funds.  In addition, the Adviser pays the  salaries and fees of all officers and
directors of the Company who are affiliated with the Adviser.
 
    Under the Investment Advisory  and Management Agreement,  the Funds pay  the
Adviser  monthly advisory fees. The fee for each  Fund is paid at an annual rate
of .50% on average daily  net assets up to $250  million, .45% on average  daily
net  assets over $250 million  and up to $500 million  and .40% on average daily
net assets over $500 million.
 
Portfolio Management
 
    Ronald R. Reuss and Douglas J. White have shared primary responsibility  for
the  day-to-day management of the Funds since they commenced operations in 1988.
Mr. Reuss has been a Senior Vice President of the Adviser since 1989. He is  the
Adviser's  chief economist and also manages other open-end and closed-end mutual
funds and  private  accounts.  Mr.  Reuss earned  an  MA  from  Cleveland  State
University and has 28 years of investment experience.
 
    Mr.  White has been a Senior Vice President of the Adviser since 1991, prior
to which  he had  been a  Vice President  since 1989.  Mr. White  manages  other
open-end  and closed-end  mutual funds and  private accounts. He  is a Chartered
Financial Analyst, earned  an MBA from  the University of  Minnesota and has  14

Transfer Agent, Dividend Disbursing Agent and Custodian
 
    Investors  Fiduciary Trust Company  ("IFTC"), 127 West  Tenth Street, Kansas
City, Missouri  64105,  (800)  874-6205,  serves as  Custodian  for  the  Funds'
portfolio  securities and  cash and  as Transfer  Agent and  Dividend Disbursing
Agent for the Funds.
 
    The Company has entered into  Shareholder Account Servicing Agreements  with
the Distributor and Piper Trust Company, an affiliate of the Distributor and the
Adviser. Under these agreements the Distributor
 
                                       17
<PAGE>
and  Piper Trust  Company provide transfer  agent and  dividend disbursing agent
services for certain shareholder accounts. For more information, see "Investment
Advisory and Other Services -- Transfer Agent and Dividend Disbursing Agent"  in
the Statement of Additional Information.
 
Portfolio Transactions and Brokerage Commissions
 
    The  Adviser selects brokers or futures  commission merchants to use for the
Funds' portfolio transactions. In making its selection, the Adviser may consider
a number  of  factors,  which are  more  fully  discussed in  the  Statement  of
Additional  Information,  including,  but  not  limited  to,  research services,
favorableness of net price,  the reasonableness of  commissions, and quality  of
services  and execution. A broker's sales of shares of any series of the Company
may also be considered a  factor if the Adviser is  satisfied that a Fund  would
receive  from that broker the most  favorable price and execution then available
for a transaction. Transactions in Tax-Exempt Securities will generally be  with
the  issuer  or with  dealers acting  on a  principal basis.  However, portfolio
transactions for the Funds which are executed on an agency basis may be effected
through the Distributor. 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 Funds' shares. The
Company has adopted a Distribution Plan  (the "Plan") as required by Rule  12b-1
under  the 1940  Act. Under  the Plan, the  Distributor is  paid a  total fee in
connection with  the  servicing  of  each Fund's  shareholder  accounts  and  in
connection  with  distribution related  services provided  with respect  to each
Fund. This fee is calculated daily and paid quarterly at an annual rate equal to
 .30% of the average daily net assets of each Fund.
 
    A portion of the total fee equal  to 0.05% of each Fund's average daily  net
assets  is  categorized  as  a  distribution  fee  intended  to  compensate  the
Distributor for  its expenses  incurred  in connection  with  the sale  of  Fund
shares.  The remaining portion of the fee,  equal to .25% of each Fund's average
daily net assets, is categorized as  a servicing fee intended to compensate  the
Distributor  for ongoing  servicing and/or maintenance  of shareholder accounts.
The Distributor has voluntarily agreed to limit the total fee payable under  the
Plan  to .24% of  each Fund's average  daily net assets.  This limitation may be
revised or terminated  at any  time after fiscal  1997 year  end. Payments  made
under  the Plan are  not tied exclusively  to expenses actually  incurred by the
Distributor and may exceed such expenses.  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  Funds. 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 Funds. See  "How
to Purchase Shares -- Purchase Price." Further information regarding the Plan is
contained in the Statement of Additional Information.
 
    The  Distributor uses  a portion  of its servicing  fee to  make payments to
Investment Executives of the Distributor  and broker-dealers which have  entered
into  sales agreements with the  Distributor. If shares of a  Fund are sold by a
representative of a broker-dealer other than the Distributor, the  broker-dealer
is  paid .20% of the average daily net assets of the Fund attributable to shares
sold by the broker-dealer's representative. If shares  of a 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  .20% of the average daily net  assets of the Fund attributable to shares
sold by the Investment Executive.

                             HOW TO PURCHASE SHARES
 
General
 
    The  Funds' shares may  be purchased at  the public offering  price from the
Distributor and from  other broker-dealers  who have sales  agreements with  the
Distributor.  The  address  of  the  Distributor  is  that  of  the  Funds.  The
Distributor reserves the right to reject any purchase order. You should be aware
that, because the  Funds do not  issue stock certificates,  Fund shares must  be
kept  in an account with  the Distributor or with  IFTC. All investments must be
arranged through your Piper Jaffray Investment Executive or other broker-dealer.
 
Purchase Price
 
    You may purchase shares of the Funds  at the net asset value per share  next
calculated  after  receipt  of  your  order  by  your  Piper  Jaffray Investment
Executive or other broker-dealer, plus a front-end sales charge as follows:

    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.
 
    During the Special Offering Period, which extends through December 31, 1996,
you  may purchase shares of  the Funds without an  initial sales charge. For any
purchase that would be subject to a sales charge outside of the Special Offering
Period, the  Funds will  impose a  contingent  deferred sales  charge of  2%  on
redemptions  during the  first 12 months  after purchase, and  1% on redemptions
during the second 12 months. This sales charge will be paid to the  Distributor.
See "How to Redeem Shares -- Contingent Deferred Sales Charge." The Adviser will
pay  the Distributor, out of its own assets, a  fee equal to 2% of the net asset
value of any shares  sold during this  period that would be  subject to a  sales
charge  outside of the  Special Offering Period.  This fee also  will be paid in
connection with certain sales that are not subject to a sales charge outside  of
the Special Offering Period, including (a) purchases by 401(k) plans, by certain
plans  which are  qualified plans under  Section 401(a) of  the Internal Revenue
Code and by tax-sheltered annuities, (b)  purchases funded by the proceeds  from
the  sale of shares of any non-money  market open-end mutual fund not managed by
the Adviser within 30 days after such  sale, (c) purchases of $500,000 or  more,
(d) exchanges of shares of Adjustable Rate Mortgage Securities Fund, a series of
Piper  Funds Inc.--II, that were originally  acquired in the American Adjustable
Rate Term Trust merger,  and (e) purchases made  with distributions received  in
connection  with  the  dissolution of  American  Government Term  Trust  Inc., a
closed-end fund previously managed  by the Adviser. The  Distributor will pay  a
portion  of  its  2%  fee  to  Piper  Jaffray  Investment  Executives  and other
broker-dealers selling shares of  the Funds. Please  contact your Piper  Jaffray
Investment Executive or other broker-dealer for more information.
 
    The Distributor also pays a portion of its Rule 12b-1 fees 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

with the Distributor  in connection  with sales of  shares of  the Funds,  other
series  of the  Company 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.
 
Purchases of $500,000 or More
 
    If you make a purchase of $500,000 or more (including purchases made under a
Letter of Intent), a 1% contingent deferred sales charge will be assessed in the
event you redeem  shares within  24 months  following the  purchase. This  sales
charge  will be paid to  the Distributor. For more  information, please refer to
the Contingent Deferred  Sales Charge  section of  "How To  Redeem Shares."  The
Distributor  currently pays  its Investment Executives  and other broker-dealers
fees in connection with these purchases as follows:

    Piper Jaffray Investment Executives and other broker-dealers generally  will
not  receive a fee in connection with purchases on which the contingent deferred
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."
 
Minimum Investments
 
    A minimum initial investment  of $250 is required.  There is no minimum  for
subsequent  investments.  The  Distributor,  in its  discretion,  may  waive the
minimum.
 
                           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.
 
    -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 any other mutual fund managed  by the Adviser that was 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 mutual funds managed by the Adviser that are 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.

                              HOW TO REDEEM SHARES
 
Normal Redemption
 
    You may redeem all or a portion of your shares on any day that a 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 redemption request.
 
    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  Funds' 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,  or if you purchased shares during  the Special Offering Period, you may
incur a contingent deferred sales charge if you redeem within 24 months. In  the
case  of investments of  $500,000 or more,  for all redemptions  made during the
24-month period 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. In the
case  of purchases made during the  Special Offering Period that otherwise would
be subject to  a front-end sales  charge, the contingent  deferred sales  charge
will  be equal to 2% of  the lesser of the net asset  value of the shares at the
time of purchase or at  the time of redemption  for redemptions made during  the
first  12 months  after purchase  and 1%  during the  second 12  months. In both
cases,  the  contingent  deferred  sales  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.
 
    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.)
 
    -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, proceeds will normally be sent to you
or your broker-dealer within  three business days. 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 checks have
cleared the banking system (normally up to 15 days from the purchase date).

                         SHAREHOLDER GUIDE TO INVESTING
 
Involuntary Redemption
 
    Each Fund reserves  the right to  redeem your  account at any  time 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
Funds  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 more automatically transferred each  month
from any of the money market fund series of the Company. 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 a 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. 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 the net  asset values of the  funds involved, except  that
investors  exchanging into a fund  which has a higher  sales charge must pay the
difference.
 
    The Company  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 (800-874-6205) for an application or for more details. The
Funds will employ reasonable procedures to confirm that a telephonic request  is
genuine, including requiring that
 
                                       24
<PAGE>
- --------------------------------------------------------------------------------
                         SHAREHOLDER GUIDE TO INVESTING
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. A Fund employing such  procedures will not be liable
for following instructions communicated by telephone that it reasonably believes
to be genuine. If a Fund does not  employ such procedures, it may be liable  for
any  losses due to unauthorized or  fraudulent telephone transactions. It may be
difficult to reach the Funds by telephone during periods when market or economic
conditions lead  to an  unusually large  volume of  telephone requests.  If  you
cannot  reach the Funds  by telephone, you should  contact your broker-dealer or
issue written  instructions  to  IFTC  at the  address  set  forth  herein.  See
"Management  -- Transfer  Agent, Dividend  Disbursing Agent  and Custodian." The
Funds reserve the right to suspend or terminate their telephone services at  any
time without notice.
 
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 for either Fund. 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 semiannually. 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. Please  refer to  "Redemption of  Shares" in  the Statement of
Additional Information for additional details.
 
Account Protection
 
    If your Fund shares are held in a Piper Jaffray account, they are  protected
in  the unlikely event of Piper Jaffray's  financial failure. Piper Jaffray is a
member of the Securities Investor Protection Corporation ("SIPC"), whose primary
purpose is to  protect the  customers of  its members  against losses  of up  to
$500,000 ($100,000 on claims for cash) in the event of a member's liquidation.
 
    In  addition to  the $500,000  SIPC protection,  Piper Jaffray  clients have
additional protection  provided  by  Aetna Casualty  and  Surety  Company.  Your
investments  in the Funds held in a Piper  Jaffray PRIME or PAT Plus account are
protected up to  $49.5 million beyond  the coverage provided  by SIPC for  total
account  protection of $50 million. Investments  held in all other Piper Jaffray
accounts are protected up to $24.5 million beyond the coverage provided by  SIPC
for  total account protection of $25 million. 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  and each Fund  is required to supply  annual and semiannual 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
 
    The net investment income of each  Fund will be declared as dividends  daily
and  paid monthly. Net  realized capital gains,  if any, will  be distributed at
least once annually.  Each daily  dividend is  payable to  Fund shareholders  of
record at the time of its declaration. "Shareholders of record" includes holders
of  shares purchased for which  payment has been received  by the Distributor or
IFTC, as  appropriate, and  excludes holders  of shares  redeemed on  that  day.
Shares  redeemed will earn dividends through the  day prior to settlement of the
redemption.
 
    The Funds  will  not  attempt  to  stabilize  distributions  and  intend  to
distribute  to their shareholders substantially all of the net investment income
earned during any period.  Thus, each Fund's dividends  can be expected to  vary
from month to month.
 
    DISTRIBUTIONS OPTIONS.  All net investment income dividends and net realized
capital  gains distributions for a Fund  generally will be payable in additional
shares of that 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 distribution  is not affected  by whether they  are reinvested  or
paid in cash.
 
                                       26
<PAGE>
                              VALUATION OF SHARES
 
    The  Funds compute  their 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
Funds have declared any applicable dividends.
 
    The  net asset value per  share for each Fund  is determined by dividing the
value of  the securities  owned  by the  Fund plus  any  cash and  other  assets
(including  interest accrued and dividends declared  but not collected) less all
liabilities  by  the  number  of  Fund  shares  outstanding.  For  purposes   of
determining  the aggregate net assets of the Funds, cash and receivables will be
valued at their face  amounts. Interest will be  recorded as accrued.  Financial
futures  are valued at the settlement price established each day by the board of
trade or exchange on which they are traded.
 
    The value  of  certain  fixed-income  securities  will  be  provided  by  an
independent pricing service, which determines these valuations at a time earlier
than  the  close of  the  Exchange. Pricing  services  consider such  factors as
security prices,  yields, maturities,  call features,  ratings and  developments
relating   to  specific   securities  in  arriving   at  securities  valuations.
Fixed-income securities for which prices  are not available from an  independent
pricing  service but where an  active market exists will  be valued using market
quotations  obtained  from  one  or  more  dealers  that  make  markets  in  the
securities. Occasionally events affecting the value of such securities may occur
between  the time valuations  are determined and  the close of  the Exchange. If
events materially  affecting the  value  of such  securities occur  during  such
period,  or if  the Company's  management determines  for any  other reason that
valuations provided  by the  pricing service  or through  dealer quotations  are
inaccurate,  such securities  will be  valued at  their fair  value according to
procedures decided upon in  good faith by the  Company's Board of Directors.  In
addition,  any securities or other assets of  a Fund for which market prices are
not readily available will be valued at their fair value in accordance with such
procedures.
 
                                   TAX STATUS
 
Federal Taxation
 
    Each Fund  is treated  as  a separate  corporation  for federal  income  tax
purposes  under  the Internal  Revenue Code  of 1986,  as amended  (the "Code").
Therefore, each Fund is treated  separately in determining whether it  qualifies
as a regulated investment company under the Code and for purposes of determining
the  net ordinary income (or  loss), net realized capital  gains (or losses) and
distributions  necessary  to  relieve  such  Fund  of  any  federal  income  tax
liability. Each Fund qualified as a regulated investment company during the last
taxable  year and  each Fund  intends to so  qualify during  the current taxable
year. If so qualified, a Fund will not be liable for federal income taxes to the
extent it distributes its taxable income to shareholders.
 
    Each Fund intends to take all actions required under the Code to ensure that
it may pay  "exempt interest  dividends." If  a Fund  meets these  requirements,
distributions  of  net  interest  income from  tax-exempt  obligations  that are
designated by the Fund as exempt-interest dividends will be excludable from  the
gross  income  of the  Fund's  shareholders. Each  Fund's  present policy  is to
designate exempt-interest  dividends  annually. Shareholders  are  required  for
information  purposes to  report exempt-interest dividends  and other tax-exempt
interest on their tax returns. Distributions paid from other interest income and
from any net  realized capital  gains will  be taxable  to shareholders  whether
received  in  cash or  in  additional shares.  Capital  gains from  the  sale or
exchange of shares are also subject to tax.
 
    Exempt  interest  dividends  attributable  to  interest  income  on  certain
tax-exempt obligations issued after August 7, 1986 to finance private activities
are  treated  as  an  item  of tax  preference  for  purposes  of  computing the
alternative minimum  tax for  individuals,  estates and  trusts. Each  Fund  may
invest  in such  obligations, provided that  at least  80% of the  value of each
Fund's net assets will at all times be invested in
 
                                       27
<PAGE>
tax-exempt obligations the interest on which  is not an item of tax  preference.
See "Taxation" in the Statement of Additional Information.
 
    If  a Fund  invests in  custodial receipts  (see "Investment  Objectives and
Policies -- Tax-Exempt Securities --  Derivative Municipal Obligations"), it  is
possible that a portion of the discount at which the Fund purchases the receipts
might have to be accrued as taxable income during the period that the Fund holds
the  receipts. Because of the  requirement that each Fund  distribute 90% of its
net investment income to maintain its status as a regulated investment  company,
the  Fund would be obligated to distribute taxable income to shareholders in the
amount of its accrued taxable income.
 
    The Tax Reform Act  of 1986 imposed new  requirements on certain  tax-exempt
bonds  which,  if not  satisfied,  could result  in  loss of  tax  exemption for
interest on such bonds, even retroactively to the date of issuance of the bonds.
Proposals may be introduced before Congress in the future, the purpose of  which
will  be to further restrict  or eliminate the federal  income tax exemption for
Tax-Exempt Securities. The Funds cannot predict what additional legislation  may
be  enacted that  may affect  shareholders. The  Funds will  avoid investment in
Tax-Exempt Securities which, in the opinion of the Adviser, pose a material risk
of the loss  of tax exemption.  Further, if  a Tax-Exempt Security  in a  Fund's
portfolio loses its exempt status, the Fund will make every effort to dispose of
such investment on terms that are not detrimental to the Fund.
 
    The  exclusion from federal  gross income of  exempt-interest dividends will
not necessarily result in exclusion  under the income tax  laws of any state  or
local governmental unit.
 
Minnesota Taxation
 
    The  portion  of exempt-interest  dividends  that is  derived  from interest
income on obligations of the State of Minnesota or its political or governmental
subdivisions, municipalities,  governmental  agencies  or  instrumentalities  is
excluded  from  the Minnesota  taxable net  income  of individuals,  estates and
trusts, provided that  the portion  of the exempt-interest  dividends from  such
Minnesota  sources  paid  to all  shareholders  represents  95% or  more  of the
exempt-interest dividends  paid  by the  Fund.  The remaining  portion  of  such
dividends,  and dividends that are not exempt-interest dividends or capital gain
dividends, are  included in  the Minnesota  taxable net  income of  individuals,
estates and trusts. Minnesota Fund intends to meet this 95% requirement, so that
the dividends it pays that are attributable to interest on Minnesota obligations
will  be excludable from  the Minnesota taxable income  of shareholders that are
individuals, estates and trusts. National Fund,  however, will not meet the  95%
requirement,  and accordingly all exempt interest dividends paid by the National
Fund will be taxable  in Minnesota. Exempt-interest  dividends are not  excluded
from  the Minnesota taxable  income of corporations  and financial institutions.
Dividends qualifying for federal income  tax purposes as capital gain  dividends
are  to be  treated by shareholders  as long-term capital  gains under Minnesota
law. However,  Minnesota  has  repealed the  favorable  treatment  of  long-term
capital  gains,  while retaining  restrictions on  the deductibility  of capital
losses. As under federal law, the portion of Social Security benefits subject to
Minnesota income tax may be affected by the amount of exempt-interest  dividends
received by the shareholders. Exempt-interest dividends attributable to interest
on  certain private activity bonds issued after  August 7, 1986 will be included
in Minnesota  alternative minimum  taxable income  of individuals,  estates  and
trusts for purposes of computing Minnesota's alternative minimum tax.
 
    The Minnesota Legislature has enacted a statement of intent that interest on
obligations of Minnesota governmental units and Indian tribes be included in net
income of individuals, estates and trusts for Minnesota income tax purposes if a
court   determines  that  Minnesota's  exemption  of  such  interest  unlawfully
discriminates against  interstate commerce  because interest  on obligations  of
governmental  issuers located  in other  states is  so included.  This provision
applies to taxable years that begin during  or after the calendar year in  which
any  such court decision  becomes final, irrespective  of the date  on which the
 
                                       28
<PAGE>
obligations were issued. Minnesota Fund is not aware of any decision in which  a
court has held that a state's exemption of interest on its own bonds or those of
its political subdivisions or Indian tribes, but not of interest on the bonds of
other  states  or  their  political subdivisions  or  Indian  tribes, unlawfully
discriminates against interstate  commerce or otherwise  contravenes the  United
States  Constitution. Nevertheless, Minnesota Fund cannot predict the likelihood
that interest on  the Minnesota  Tax-Exempt Securities  held by  the Fund  would
become taxable under this Minnesota statutory provision.
 
    The foregoing discussion relates to federal and Minnesota income taxation as
of the date of this Prospectus. For a more detailed discussion of the income tax
consequences  of  investing  in  shares  of the  Funds,  see  "Taxation"  in the
Statement of Additional Information.  Before investing in  either of the  Funds,
you  should check for any further  consequences under applicable local and state
tax laws.
 
                            PERFORMANCE COMPARISONS
 
    Advertisements and other sales literature for  the Funds may refer to  their
"yield,"  "tax equivalent yield," "average  annual total return" and "cumulative
total return." All  such figures are  based on historical  earnings and are  not
intended to indicate future performance. The return on and principal value of an
investment  in  the Funds  will fluctuate,  so that  an investor's  shares, when
redeemed, may be worth more or less than their original cost.
 
    The advertised yield of a Fund will be based upon a 30-day period stated  in
the advertisement. Yield is calculated by dividing the net investment income per
share   (as  defined  under   Securities  and  Exchange   Commission  rules  and
regulations) earned during the period by the maximum offering price per share on
the last day of the period. The  result is then annualized using a formula  that
provides for semiannual compounding of income.
 
    Tax  equivalent yield is  calculated by applying the  stated income tax rate
only to that portion of the yield  that is exempt from taxation. The  tax-exempt
portion of the yield is divided by the number 1 minus the stated income tax rate
(E.G.,  1- 28% = 72%). The result is then added to that portion of the yield, if
any, that is not tax exempt.
 
    The average annual  total 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 a 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.
Such total  return quotations  may be  accompanied by  quotations which  do  not
reflect  the  reduction in  value of  the  initial investment  due to  the sales
charge, and which thus will be higher.
 
    Comparative performance information may  also be used from  time to time  in
advertising  the Funds' shares. For example, advertisements may compare a Fund's
performance to  that  of  various  unmanaged  market  indices,  or  may  include
performance  data from  Lipper Analytical  Services, Inc.,  Morningstar, Inc. or
other entities  or  organizations  that  track  the  performance  of  investment
companies.
 
    For additional information regarding comparative performance information and
the  calculation of a Fund's  yield, tax equivalent yield  and total return, see
"Performance Comparisons" in the Statement of Additional Information.
 
    Advertisements and  other  sales  literature  may also  refer  to  a  Fund's
effective  duration. Effective duration estimates  the interest rate risk (price
volatility) of a security, I.E., how much the value of the security is  expected
to  change  with a  given  change in  interest  rates. The  longer  a security's
effective duration, the
 
                                       29
<PAGE>
more sensitive  its price  is to  changes  in interest  rates. For  example,  if
interest  rates were  to increase  by 1%,  the market  value of  a bond  with an
effective duration of  five years  would decrease by  about 5%,  with all  other
factors  being constant.  It is important  to understand that,  while a valuable
measure, effective duration is  based upon certain  assumptions and has  several
limitations.  It  is most  effective as  a  measure of  interest rate  risk when
interest rate  changes  are  small,  rapid and  occur  equally  across  all  the
different  points  of  the  yield  curve.  In  addition,  effective  duration is
difficult to  calculate precisely,  especially in  the case  of a  bond that  is
callable prior to maturity.
 
                              GENERAL INFORMATION
 
    The Company, which was organized under the laws of the State of Minnesota in
1986, is authorized to issue a total of 10 trillion shares of common stock, with
a  par value of $.01 per share. Three hundred and ninety billion of these shares
have been authorized by the Board of  Directors to be issued in twelve  separate
series,  as follows: Growth Fund, Emerging  Growth Fund, Growth and Income Fund,
Small Company  Growth  Fund  (formerly Equity  Strategy  Fund),  Balanced  Fund,
Government   Income  Fund,   Intermediate  Bond   Fund  (formerly  Institutional
Government Income Portfolio), National Tax-Exempt Fund and Minnesota  Tax-Exempt
Fund,  each of which has  ten billion authorized shares,  and Money Market Fund,
Tax-Exempt Money Market  Fund and  U.S. Government  Money Market  Fund, each  of
which has one hundred billion authorized shares.
 
    The  Board  of  Directors  is  empowered  under  the  Company's  Articles of
Incorporation to issue additional series  of the Company's common stock  without
shareholder   approval.  In  addition,  the  Board  of  Directors  may,  without
shareholder approval, create and issue one or more additional classes of  shares
within  each Fund,  as well  as within any  other series  of the  Company or any
series created in the future. See "Capital Stock and Ownership of Shares" in the
Statement of Additional Information.
 
    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  of  a  series  has  one  vote  (with  proportionate  voting  for
fractional  shares) irrespective of the relative  net asset value of the series'
shares. On some issues,  such as the  election of directors,  all shares of  the
Company  vote together as one series.  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.
 
    The Bylaws of  the Company provide  that shareholder meetings  be held  only
with  such frequency as required under  Minnesota law. Minnesota corporation law
requires only that the Board of  Directors convene shareholder 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  the
Company  may demand a regular meeting of shareholders by written notice given to
the chief executive officer or chief financial officer of the Company. Within 30
days after receipt of the demand, the  Board of Directors shall cause a  regular
meeting  of shareholders to be called, which meeting shall be held no later than
90 days after  receipt of  the demand,  all at the  expense of  the Company.  In
addition,  the  1940  Act requires  a  shareholder  vote for  all  amendments to
fundamental investment policies and restrictions  and for certain amendments  to
investment advisory contracts and Rule 12b-1 distribution plans.

Pending Legal Proceedings
 
    Complaints  have  been  brought  against  the  Adviser  and  the Distributor
relating to another series of the Company and to other investment companies  for
which  the Adviser acts or has acted  as investment adviser or subadviser. These
lawsuits do not involve the Funds.
 
    A number of complaints have been brought in federal and state court  against
the  Institutional Government Income  Portfolio ("PJIGX") series  of the Company
(such series  has  been  renamed  Intermediate  Bond  Fund),  the  Adviser,  the
Distributor,  and certain individuals affiliated or formerly affiliated with the
Adviser and the Distributor. On February 13, 1996, a Settlement Agreement became
effective for the consolidated class action  lawsuit, titled In Re: PIPER  FUNDS
INC.   INSTITUTIONAL  GOVERNMENT   INCOME  PORTFOLIO   LITIGATION.  The  Amended
Consolidated Class Action Complaint was filed on October 5, 1994, in the  United
States  District Court, District  of Minnesota, against  PJIGX, the Adviser, the
Distributor, William H. Ellis and Edward  J. Kohler, and had alleged the  making
of  materially  misleading statements  in the  prospectus, common  law negligent
misrepresentation and breach  of fiduciary duty.  The Settlement Agreement  will
provide approximately $67.5 million, together with interest earned, less certain
disbursements  and attorney  fees, to class  members in  payments scheduled over
approximately three years. Such payments will be made by Piper Jaffray Companies
Inc. and the Adviser and will not be  an obligation of the Company. A number  of
lawsuits  and  arbitrations  brought  by some  of  the  investors  who requested
exclusion from the settlement class remain pending.
 
    Complaints also have  been filed in  state and federal  court relating to  a
number  of  closed-end  investment  companies managed  by  the  Adviser  and two
open-end investment companies for which the Adviser has acted as subadviser. The
complaints, which ask  for rescission  of plaintiff  shareholders' purchases  or
compensatory damages, plus interest, costs and expenses, generally allege, among
other  things,  certain  violations  of federal  and/or  state  securities laws,
including  the  making  of  materially  misleading  statements  in  prospectuses
concerning  investment  policies  and  risks.  In  addition  to  the  Settlement
Agreement discussed above, a settlement agreement has been reached with  respect
to  a consolidated  complaint relating  to four  closed-end investment companies
managed by the Adviser and  agreements-in-principle have been reached to  settle
certain  other complaints. The  Adviser and the Distributor  also are subject to
regulatory inquiries related to various funds or assets managed by the  Adviser.
See "Pending Litigation" in the Statement of Additional Information.
 
    The  Adviser  and  the  Distributor  do  not  believe  that  the settlements
discussed above,  any  agreement-in-principle  to  settle,  or  any  outstanding
complaint  or action in  arbitration or regulatory inquiry  will have a material
adverse effect  on their  ability to  perform under  their agreements  with  the
Company or a material adverse effect on the Funds.

                         TAX-EXEMPT VS. TAXABLE INCOME
 
    The  tables below show  the approximate yields  that taxable securities must
earn to equal federally tax-exempt yields  and yields that are exempt from  both
federal  and Minnesota  income taxes  under selected  combined federal/Minnesota
income tax  brackets, which  reflect effective  combined rates  after  deducting
Minnesota taxes from federal income. The combined federal/Minnesota tax brackets
assume  the federal rate listed in the  column above each combined bracket and a
Minnesota income tax rate of 8.5% (except the 33.8% combined rate, which assumes
a Minnesota rate of 8%). The 39.6% federal rate and the 8.5% Minnesota rate  are
the  highest rates in effect for individuals  in 1996 and currently scheduled to
be in effect for individuals in 1997.

    These charts  do  not  take  into consideration  any  federal  or  Minnesota
alternative  minimum tax. In addition, each chart  is based upon yields that are
derived solely from tax-exempt income. To  the extent a Fund's advertised  yield
is derived from taxable income, the Fund's equivalent taxable yield will be less
than set forth in the chart. The tax-free yields used in these charts should not
be  considered as representations of any particular  rates of return and are for
purposes of illustration only.

                      INVESTMENT POLICIES AND RESTRICTIONS

     The shares of Piper Funds Inc. (the "Company") are currently offered in
twelve series.  This Statement of Additional Information relates to two of those
series, National Tax-Exempt Fund ("National Fund") and Minnesota Tax-Exempt Fund
("Minnesota Fund") (sometimes referred to herein as a "Fund" or, collectively,
as the "Funds").  The investment objectives and policies of the Funds are set
forth in the Prospectus.  Certain additional investment information is set forth
below.

REPURCHASE AGREEMENTS

     Each Fund may invest in repurchase agreements.  The Funds' custodian will
hold the securities underlying any repurchase agreement or such securities will
be part of the Federal Reserve Book Entry System.  The market value of the
collateral underlying the repurchase agreement will be determined on each
business day.  If at any time the market value of the collateral falls below the
repurchase price of the repurchase agreement (including any accrued interest),
the respective Fund will promptly receive additional collateral (so the total
collateral is an amount at least equal to the repurchase price plus accrued
interest).

     The Funds have received from the Securities and Exchange Commission an
exemptive order permitting the Funds, along with the other series of the
Company, closed-end and other open-end investment companies managed by Piper
Capital Management Incorporated (the "Adviser"), and all future series of the
Company and all future investment companies advised by the Adviser or its
affiliates, to deposit uninvested cash balances into a single joint account to
be used to enter into one or more large repurchase agreements.

WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES

     Each Fund may purchase securities on a "when-issued" basis and may purchase
or sell securities on a "forward commitment" basis.  When a Fund purchases
securities on a when-issued or forward commitment basis, it will maintain in a
segregated account with its custodian cash or liquid securities having an
aggregate value equal to the amount of such purchase commitments until payment
is made; the Fund will likewise segregate securities it sells on a forward
commitment basis.

PUTS

     To help assure appropriate liquidity, each Fund may acquire Tax-Exempt
Securities (as defined in the Funds' Prospectus) which provide for the right to
resell them to the issuer, a bank or a broker-dealer at a specified price within
a specified period of time prior to the maturity date of such obligation.  Such
a right to resell, which is commonly known as a "put," may be sold, transferred
or assigned only with the underlying security or securities.  If an issuer, bank
or broker-dealer should default on its obligation to repurchase a security, a
Fund might be unable to recover all or a portion of any loss sustained from
having to sell the security elsewhere.  It


                                       -2-

<PAGE>

will be each Fund's policy to enter into puts only with issuers, banks or
broker-dealers that are determined by the Adviser to present minimal credit
risks.

DIVERSIFICATION

     Although Minnesota Fund is characterized as a nondiversified fund under the
Investment Company Act of 1940, as amended (the "1940 Act"), the Fund must meet
certain diversification requirements in order to qualify as a regulated
investment company for federal income tax purposes.  To so qualify, the Fund
must diversify its holdings so that, at the close of each quarter of its taxable
year, (a) at least 50% of the value of its total assets consists of cash, cash
items, securities issued by the U.S. Government, its agencies and
instrumentalities, the securities of other regulated investment companies, and
other securities limited generally with respect to any one issuer to not more
than 5% of the total assets of the Fund and not more than 10% of the outstanding
voting securities of such issuer, and (b) not more than 25% of the value of its
total assets is invested in the securities of any issuer (other than securities
issued by the U.S. Government, its agencies or instrumentalities or the
securities of other regulated investment companies), or in two or more issuers
that the Fund controls and that are engaged in the same or similar trades or
businesses.

ILLIQUID SECURITIES

     As set forth in the Prospectus, the Funds may invest in Rule 144A
securities, commercial paper issued pursuant to Rule 4(2) under the Securities
Act of 1933, and municipal lease obligations, and treat such securities as
liquid when they have been determined to be liquid by the Board of Directors of
the Company or by the Adviser subject to the oversight of and pursuant to
procedures adopted by the Board of Directors.  Under these procedures, factors
taken into account in determining the liquidity of a security include (a) the
frequency of trades and quotes for the security; (b) the number of dealers
willing to purchase or sell the security and the number of other potential
purchasers; (c) dealer undertakings to make a market in the security; and
(d) the nature of the security and the nature of the marketplace trades (e.g.,
the time needed to dispose of the security, the method of soliciting offers and
the mechanics of transfer).  With respect to Rule 144A securities, investing in
such securities could have the effect of increasing the level of Fund
illiquidity to the extent that qualified institutional buyers become, for a
time, uninterested in purchasing these securities.

PORTFOLIO TURNOVER

     Portfolio turnover is the ratio of the lesser of annual purchases or sales
of portfolio securities to the average monthly value of portfolio securities,
not including securities maturing in less than 12 months.  A 100% portfolio
turnover rate would occur, for example, if the lesser of the value of purchases
or sales of portfolio securities for a particular year were equal to the average
monthly value of the portfolio securities owned during such year.

INVESTMENT RESTRICTIONS

     In addition to the investment objectives and policies set forth in the
Prospectus, each Fund is subject to certain fundamental and nonfundamental
investment restrictions, as set forth below.  Fundamental investment
restrictions  may not be changed without the vote of a majority of a Fund's
outstanding shares.  "Majority," as used in the Prospectus and in this Statement
of Additional Information, means the lesser of (a) 67% of a Fund's outstanding
shares present at a meeting of the holders if more than 50% of the outstanding
shares are present in person or by proxy or (b) more than 50% of a Fund's
outstanding shares.

     As fundamental investment restrictions, neither Fund will:

     1.   Issue any senior securities (as defined in the 1940 Act) other than as
set forth in restriction #2 below and except to the extent that using options
and futures contracts or purchasing or selling securities on a when-issued or
delayed delivery basis may be deemed to constitute issuing a senior security.

     2.   Borrow money (provided that each Fund may enter into reverse
repurchase agreements) except from banks for temporary or emergency purposes.
Each Fund may borrow money in an amount up to 10% of the value of its total
assets.  With respect to each Fund, interest paid on borrowed funds will
decrease the net earnings of the Fund.  Neither Fund will purchase portfolio
securities while outstanding borrowing exceeds 5% of the value of such Fund's
total assets.  Neither Fund will borrow money for leverage purposes (provided
that each Fund may enter into reverse repurchase agreements for such purposes).

     3.   Mortgage, pledge or hypothecate its assets except in an amount not
exceeding 10% of the value of its total assets to secure temporary or emergency
borrowing.  For purposes of this restriction, collateral arrangements for margin
deposits on futures contracts or with respect to the writing of options are not
deemed to be a pledge of assets.

     4.   Purchase or sell commodities or commodities futures contracts,
provided that each of the Funds may enter into financial futures contracts and
engage in related options transactions.

     5.   Purchase or sell real estate or real estate mortgage loans, except
that the Funds may invest in Tax-Exempt Securities secured by real estate or
interests therein.

     6.   Act as an underwriter of securities of other issuers, except insofar
as each Fund may be technically deemed an underwriter under the federal
securities laws in connection with the disposition of portfolio securities.

     As nonfundamental investment restrictions that may be changed at any time
without shareholder approval, neither Fund will:


                                       -4-

<PAGE>

     1.   Make short sales of securities, provided that each Fund for hedging
purposes may enter into financial futures contracts and engage in related
options transactions.

     2.   Purchase any securities on margin except to obtain such short-term
credits as may be necessary for the clearance of transactions and except that
the Funds may make margin deposits in connection with futures contracts.

     3.   Write, purchase or sell puts, calls or combinations thereof except for
hedging purposes.

     4.   Purchase or retain the securities of any issuer if, to the Fund's
knowledge, those officers or directors of the Company or its affiliates or of
its investment adviser who individually own beneficially more than 0.5% of the
outstanding securities of such issuer, together own more than 5% of such
outstanding securities.

     5.   Invest for the purpose of exercising control or management.

     6.   Purchase or sell oil, gas or other mineral leases, rights or royalty
contracts, except that the Funds may purchase or sell securities of companies
investing in the foregoing.

     7.   Invest more than 5% of the value of its total assets in securities of
other investment companies except as part of a merger, consolidation or
acquisition of assets.

     8.   Invest more than 15% of the value of its net assets in illiquid
securities.

     9.   Invest more than 5% of the value of its total assets in foreign
securities.

     10.  Invest more than 5% of the value of its total assets in the securities
of any issuers which, with their predecessors, have a record of less than three
years' continuous operation.  (Securities of such issuers will not be deemed to
fall within this limitation if they are guaranteed by an entity in continuous
operation for more than three years.)

     11.  Loan its portfolio securities.

     12.  Invest in warrants.

     The identification of the issuer of a Tax-Exempt Security depends on the
terms and conditions of the obligation.  If the assets and revenues of an
agency, authority, instrumentality or other political subdivision are separate
from those of the government creating the subdivision, and the obligation is
backed only by the assets and revenues of the subdivision, such subdivision will
be regarded as the sole issuer.  Similarly, in the case of a nongovernmental
user, such as an industrial corporation or a privately owned or operated
hospital, if the security is backed only by the assets and revenues of the
nongovernmental user then such non-


                                       -5-

<PAGE>

governmental user will be deemed to be the sole issuer.  If in either case the
creating government or another entity guarantees an obligation, and the value of
all securities issued or guaranteed by the guarantor and owned by a Fund exceeds
10% of the value of such Fund's total assets, the guarantee will be regarded as
a separate security and treated as an issue of such government or entity.

     Any investment restriction or limitation referred to above or in the
Prospectus, except the borrowing policy, which involves a maximum percentage of
securities or assets shall not be considered to be violated unless an excess
over the percentage occurs immediately after an acquisition of securities or
utilization of assets and such excess results therefrom.

SPECIAL CONSIDERATIONS REGARDING INVESTMENTS IN MINNESOTA TAX-EXEMPT SECURITIES

     As described in the Prospectus, except during temporary defensive periods,
Minnesota Fund will invest in Minnesota Tax-Exempt Securities.  The Fund is
therefore susceptible to political, economic or regulatory factors affecting
issuers of Minnesota Tax-Exempt Securities.  The following information, together
with the information set forth in the Prospectus, provides only a brief summary
of the complex factors affecting the financial situation in Minnesota.  This
information is derived from sources that are generally available to investors
and is based in part on information obtained from various state and local
agencies in Minnesota.  It should be noted that the creditworthiness of
obligations issued by local Minnesota issuers may be unrelated to the
creditworthiness of obligations issued by the State of Minnesota, and that there
is no obligation on the part of the State to make payment on such local
obligations in the event of default.

     MINNESOTA ECONOMY.  The State relies heavily on a progressive individual
income tax and a retail sales tax for revenue, which results in a fiscal system
unusually sensitive to economic conditions.

     Diversity and a significant natural resource base are two important
characteristics of the Minnesota economy.  Generally, the structure of the
State's economy parallels the structure of the United States economy as a whole.
There are, however, employment concentrations in durable goods and non-durable
goods manufacturing, particularly industrial machinery, instruments and
miscellaneous, food, paper and related industries, and printing and publishing.
During the period from 1980 to 1990, overall employment growth in Minnesota
lagged behind national employment growth, in large part due to declining
agricultural employment.  The rate of non-farm employment growth in Minnesota
exceeded the rate of national growth, however, in the period of 1990 to 1995.
Since 1980, Minnesota per capita income generally has remained above the
national average.  During 1994 and 1995, the State's monthly unemployment rate
was less than the national unemployment rate.

     There can be no assurance that Minnesota's economy and fiscal condition
will not materially change in the future or that future difficulties will not
occur.  Economic difficulties and the resultant impact on State and local
government


                                       -6-

<PAGE>

finances may adversely affect the market value of obligations in the portfolio
of Minnesota Fund or the ability of respective obligors to make timely payment
of the principal and interest on such obligations.

meeting of the Board of Directors attended.  (The per-meeting fee is based on
the combined total assets of the Company and Piper Institutional Funds Inc.)
The per-meeting fee is based upon asset size and is $250 if assets are under

                     INVESTMENT ADVISORY AND OTHER SERVICES

     The investment adviser for the Funds is Piper Capital Management
Incorporated (the "Adviser").  Its affiliate, Piper Jaffray Inc. (the
"Distributor"), acts as the Funds' distributor.  Each will act as such pursuant
to a written agreement which will be periodically approved by the directors or
the shareholders of the Funds.  The address of both the Adviser and the
Distributor is Piper Jaffray Tower, 222 South Ninth Street, Minneapolis,
Minnesota 55402.

CONTROL OF THE ADVISER AND THE DISTRIBUTOR

     The Adviser and the Distributor are both wholly owned subsidiaries of Piper
Jaffray Companies Inc.,  a publicly held corporation which is engaged through
its subsidiaries in various aspects of the financial services industry.

INVESTMENT ADVISORY AND MANAGEMENT AGREEMENT

     The Adviser acts as the investment adviser of the Funds under an Investment
Advisory and Management Agreement which has been approved by the Board of
Directors (including a majority of the directors who are not parties to the
agreement, or interested persons of any such party, other than as directors of
the Funds) and the shareholders of the Funds.

     The Investment Advisory and Management Agreement will terminate
automatically in the event of its assignment.  In addition, the agreement is
terminable at any time, without penalty, by the Board of Directors of the
Company or by vote of a majority of the Company's outstanding voting securities
on not more than 60 days' written notice to the Adviser, and by the Adviser on
60 days' written notice to the Company.  The agreement may be terminated with
respect to a particular Fund at any time by a vote of the holders of a majority
of the outstanding voting securities of such Fund, upon 60 days' written notice
to the Adviser.  Unless sooner terminated, the agreement shall continue in
effect for more than two years after its execution only so long as such
continuance is specifically approved at least annually by either the Board of
Directors or by a vote of a majority of the outstanding voting securities of the
Company, provided that in either event such continuance is also approved by a
vote of a majority of the directors who are not parties to such agreement, or
interested persons of such parties, cast in person at a meeting called for the
purpose of voting on such approval.  If a majority of the outstanding voting
securities of either Fund approves the agreement, the agreement shall continue
in effect with respect to such approving Fund whether or not the shareholders of
the other Fund approve the agreement.

     Pursuant to the Investment Advisory and Management Agreement, the Funds pay
the Adviser monthly advisory fees equal on an annual basis to a certain
percentage of each Fund's average net assets as set forth in the following
table.

     Average Net Asset Values              as Percentage of
          of each Fund                     Average Net Assets
     ------------------------             -------------------
     On the first $250,000,000                   .50%
     On the next $250,000,000                    .45%
     On average assets of over
       $500,000,000                              .40%

     For the fiscal years ended September 30, 1994, 1995 and 1996, National Fund
paid $368,373, $298,729 and $258,789, respectively, and Minnesota Fund paid
$852,616, $706,675 and $660,926, respectively, to the Adviser pursuant to the
Investment Advisory and Management Agreement.

     Under the Investment Advisory and Management Agreement, the Adviser
provides each Fund with advice and assistance in the selection and disposition
of that Fund's investments.  All investment decisions are subject to review by
the Board of Directors of the Company.  The Adviser is obligated to pay the
salaries and fees of any affiliates of the Adviser serving as officers or
directors of the Funds.

     The same security may be suitable for one or both of the Funds and/or for
other series of the Company or other funds or private accounts managed by the
Adviser or its affiliates.  If and when two or more funds or accounts
simultaneously purchase or sell the same security, the transactions will be
allocated as to price and amount in accordance with arrangements equitable to
each fund or account.  The simultaneous purchase or sale of the same securities
by both Funds or by either of the Funds and other series of the Company or other
funds or accounts may have a detrimental effect on a Fund, as this may affect
the price paid or received by that Fund or the size of the position obtainable
or able to be sold by that Fund.

EXPENSES

     The expenses of each Fund are deducted from their income before dividends
are paid.  These expenses include, but are not limited to, organizational costs,
fees paid to the Adviser, fees and expenses of officers and directors who are
not affiliated with the Adviser, taxes, interest, legal fees, transfer agent,
dividend disbursing agent and custodian fees, audit fees, brokerage fees and
commissions, fees and expenses of registering and qualifying the Funds and their
shares for distribution under federal and state securities laws, expenses of
preparing prospectuses and statements of additional information and of printing
and distributing prospectuses and statements of additional information annually
to existing shareholders, the expenses of reports to shareholders, shareholders'
meetings and proxy solicitations, distribution expenses pursuant to the Rule
12b-1 plan, and other expenses which are not expressly assumed by the Adviser
under the Investment Advisory and Management Agreement.  Any general expenses of
the Company that are not readily identifiable as belonging to a particular
series of the Company will be allocated among the series based upon the relative
net assets of the series at the time such expenses were incurred.

DISTRIBUTION PLAN

     Rule 12b-1(b) under the 1940 Act provides that any payments made by the
Funds in connection with financing the distribution of their shares may only be
made pursuant to a written plan describing all aspects of the proposed financing
of distribution, and also requires that all agreements with any person relating
to the implementation of the plan must be in writing.  Because some of the
payments described below to be made by the Funds are distribution expenses
within the meaning of Rule 12b-1, the Company has entered into an Underwriting
and Distribution Agreement with the Distributor pursuant to a Distribution Plan
adopted in accordance with such Rule.

     Rule 12b-1(b)(1) requires that such plan be approved by a majority of a
Fund's outstanding shares, and Rule 12b-1(b)(2) requires that such plan,
together with any related agreements, be approved by a vote of the Board of
Directors and of the directors who are not interested persons of the Company and
who have no direct or indirect interest in the operation of the plan or in the
agreements related to the plan, cast in person at a meeting called for the
purpose of voting on such plan or agreement.  Rule 12b-1(b)(3) requires that the
plan or agreement provide, in substance:

          (a)  that it shall continue in effect for a period of more than one
     year from the date of its execution or adoption only so long as such
     continuance is specifically approved at least annually in the manner
     described in paragraph (b)(2) of Rule 12b-1;

          (b)  that any person authorized to direct the disposition of moneys
     paid or payable by the Company pursuant to the plan or any related
     agreement shall provide to the Company's Board of Directors, and the
     directors shall review, at least quarterly, a written report of the amounts
     so expended and the purposes for which such expenditures were made; and

          (c)  in the case of a plan, that it may be terminated at any time by a
     vote of a majority of the members of the Board of Directors of the Company
     who are not interested persons of the Company and who have no direct or
     indirect financial interest in the operation of the plan or in any
     agreements related to the plan or by a vote of a majority of the
     outstanding voting securities of a Fund.

     Rule 12b-1(b)(4) requires that such a plan may not be amended to increase
materially the amount to be spent for distribution without shareholder approval
and that all material amendments of the plan must be approved in the manner
described in paragraph (b)(2) of Rule 12b-1.

     Rule 12b-1(c) provides that the Company may rely upon Rule 12b-1(b) only if
the selection and nomination of the Company's disinterested directors are
committed to the discretion of such disinterested directors.  Rule 12b-1(e)
provides that the Company may implement or continue a plan pursuant to Rule 12b-
1(b) only if the directors who vote to approve such implementation or
continuation conclude, in the exercise of reasonable business judgment and in
light of their fiduciary duties under state law, and under Sections 36(a) and
(b) of the 1940 Act,


                                      -13-

<PAGE>

that there is a reasonable likelihood that the plan will benefit the Company and
its shareholders.  The Board of Directors has concluded that there is a
reasonable likelihood that the Distribution Plan will benefit the Company and
its shareholders.

     Pursuant to the provisions of the Distribution Plan, each Fund pays a fee
to the Distributor at a monthly rate of 1/12 of .30% of such Fund's average
daily net assets in connection with servicing of the Fund's shareholder accounts
and in connection with distribution-related services provided with respect to
the Funds.  A portion of the total fee (to be determined from time to time by
the Board of Directors) may be paid as a distribution fee and will be used by
the Distributor to cover expenses that are primarily intended to result in, or
that are primarily attributable to, the sale of shares of the Funds
("Distribution Expenses"), and the remaining portion of the fee may be paid as a
shareholder servicing fee and will be used by the distributor to provide
compensation for ongoing servicing and/or maintenance of shareholder accounts
with respect to the Funds ("Shareholder Servicing Costs").  Distribution
Expenses under the Plan include, but are not limited to, initial and ongoing
sales compensation (in addition to sales charges) paid to Investment Executives
of the Distributor and to other broker-dealers; expenses incurred in the
printing of prospectuses, statements of additional information and reports used
for sales purposes; expenses of preparation and distribution of sales
literature; expenses of advertising of any type; an allocation of the
Distributor's overhead; and payments to and expenses of persons who provide
support services in connection with the distribution of Fund shares.
Shareholder Servicing Costs include all expenses of the Distributor incurred in
connection with providing administrative or accounting services to shareholders,
including, but not limited to, an allocation of the Distributor's overhead and
payments made to persons, including employees of the Distributor, who respond to
inquiries of shareholders of the Funds regarding their ownership of shares or
their accounts with the Funds, or who provide other administrative or accounting
services not otherwise required to be provided by the Funds' Adviser or transfer
agent.

     For the fiscal years ended September 30, 1994, 1995 and 1996, the
Distributor voluntarily limited amounts payable under the Distribution Plan to
 .20%, .22% and .22%, respectively, of average daily net assets for each Fund.
During such periods, National Fund paid distribution fees to the Distributor of
$147,349, $129,534 and $107,785 respectively, and Minnesota Fund paid 
distribution fees to the Distributor of $341,046, $306,351 and $275,220, 
respectively.  The Distributor has voluntarily limited amounts payable under the
Distribution Plan during fiscal 1997 to an annual rate of .24% of the average 
daily net assets of each Fund.  The Distributor may terminate its voluntary fee
limitation at any time in its discretion.

UNDERWRITING AND DISTRIBUTION AGREEMENT

     Pursuant to the Underwriting and Distribution Agreement, the Distributor
has agreed to act as the principal underwriter for the Funds in the sale and
distribution to the public of shares of the Funds, either through dealers or
otherwise.  The Distributor has agreed to offer such shares for sale at all
times when such shares are available for sale and may lawfully be offered for
sale and sold.  As compensation for its services, in addition to receiving its
distribution fees pursuant to the Distribution Plan discussed above, the
Distributor receives the sales load on sales of Fund shares set forth in the
Prospectus.

     The following table sets forth the aggregate dollar amount of underwriting
commissions paid by each Fund for the fiscal years ended September 30, 1994,
1995 and 1996, the amount of such commissions retained by the Distributor and

TRANSFER AGENT AND DIVIDEND DISBURSING AGENT

     Investors Fiduciary Trust Company ("IFTC"), the transfer agent for the
Company, maintains certain omnibus shareholder accounts for each of the Funds.
Each such omnibus account represents the accounts of a number of individual
shareholders of a Fund.  The Company has entered into  Shareholder Account
Servicing Agreements with the Distributor and Piper Trust Company ("Piper
Trust"), pursuant to which the Distributor and Piper Trust provide certain
transfer agent and dividend disbursing agent services for the underlying
individual shareholder accounts held at the respective companies.  Pursuant to
such


                                      -15-

<PAGE>

Agreements, the Distributor and Piper Trust have agreed to perform the usual and
ordinary services of transfer agent and dividend disbursing agent not performed
by IFTC with respect to the underlying individual shareholder accounts,
including, without limitation, the following:  maintaining all shareholder
accounts, preparing shareholder meeting lists, mailing shareholder reports and
prospectuses, tracking shareholder accounts for blue sky and Rule l2b-1
purposes, withholding taxes on nonresident alien and foreign corporation
accounts, preparing and mailing checks for disbursement of income dividends and
capital gains distributions, preparing and filing U.S. Treasury Department Form
1099 for all shareholders, preparing and mailing confirmation forms to
shareholders and dealers with respect to all purchases, exchanges and
liquidations of series shares and other transactions in shareholder accounts for
which confirmations are required, recording reinvestments of dividends and
distributions in series shares, recording redemptions of series shares, and
preparing and mailing checks for payments upon redemption and for disbursements
to withdrawal plan holders.  As compensation for such services, the Distributor
and Piper Trust are paid an annual fee of $7.50 per active shareholder account
(defined as an account that has a balance of shares) and $1.60 per closed
account (defined as an account that does not have a balance of shares, but has
had activity within the past 12 months) by each Fund.  Such fee is payable on a
monthly basis at a rate of 1/12 of the annual per-account charge.  Such fee
covers all services listed above, with the exception of preparing shareholder
meeting lists and mailing shareholder reports and prospectuses.  These services,
along with proxy processing (if applicable) and other special service requests,
are billable as performed at a mutually agreed upon fee in addition to the
annual fee noted above, provided that such mutually agreed upon fee shall be
fair and reasonable in light of the usual and customary charges made by others
for services of the same nature and quality.

     During the fiscal year ended September 30, 1996, National Fund paid $13,073
and Minnesota Fund paid $23,612 to the Distributor under the Shareholder Account
Servicing Agreement.  The Funds did not make any payments to Piper Trust under
the Shareholder Account Servicing Agreement.

               PORTFOLIO TRANSACTIONS AND ALLOCATION OF BROKERAGE

     Because each Fund's portfolio is composed exclusively of debt, rather than
equity securities, most of the Funds' portfolio transactions are effected
without the payment of brokerage commissions, but at net prices which usually
include a markup.  Most of the Funds' transactions are with the issuer or with
major dealers on a principal basis acting for their own account and not as
brokers.  However, portfolio transactions for the Funds which are executed on an
agency basis may be effected through the Distributor on a securities exchange if
the commissions, fees or other remuneration received by the Distributor are
reasonable and fair compared to the commissions, fees or other remuneration paid
to other brokers or other futures commission merchants in connection with
comparable transactions involving similar securities or similar futures
contracts or options on futures contracts being purchased or sold on an exchange
during a comparable period of time.  In effecting portfolio transactions through
the Distributor, the Funds intend to comply with Section 17(e)(1) of the 1940
Act.


                                      -16-

<PAGE>

     The Adviser is responsible for effecting securities transactions for each
Fund.  In placing orders for securities transactions, the primary criterion for
the selection of a broker-dealer is the ability of the broker-dealer, in the
opinion of the Adviser, to secure prompt execution of the transactions at the
most favorable net price, considering the state of the market at the time.
Frequently the Adviser selects a broker-dealer to effect a particular
transaction without contacting all broker-dealers who might be able to effect
such transaction, because of the volatility of the money market and the desire
to accept a particular price for a security because the price offered by the
broker-dealer meets a Fund's guidelines for profit, yield, or both.

     When consistent with the objectives of prompt execution and favorable net
price, business may be placed with broker-dealers who furnish investment
research or services to the Adviser.  Such research or services include advice,
both directly and in writing, as to the value of securities; the advisability of
investing in, purchasing or selling securities; and the availability of
securities, or purchasers or sellers of securities; as well as analyses and
reports concerning issues, industries, securities, economic factors and trends,
portfolio strategy and the performance of accounts.  This allows the Adviser to
supplement its own investment research activities and enables the Adviser to
obtain the views and information of individuals and research staffs of many
different securities firms prior to making investment decisions for the Funds.
To the extent portfolio transactions are effected with broker-dealers who
furnish research services to the Adviser, the Adviser receives a benefit, not
capable of evaluation in dollar amounts, without providing any direct monetary
benefit to the Funds from these transactions.  The Adviser believes that most
research services obtained by it generally benefit several or all of the
investment companies and private accounts which it manages, as opposed to solely
benefiting one specific managed fund or account.  Normally, research services
obtained through managed funds or accounts investing in common stocks would
primarily benefit the managed funds or accounts which invest in common stock;
similarly, services obtained from transactions in fixed-income securities would
normally be of greater benefit to the managed funds or accounts which invest in
debt securities.

     The Adviser has not entered into any formal or informal agreements with any
broker-dealers, nor does it maintain any "formula" which must be followed in
connection with the placement of the Funds' portfolio transactions in exchange
for research services provided the Adviser, except as noted below.  However, the
Adviser does maintain an informal list of broker-dealers, which is used from
time to time as a general guide in the placement of the Funds' business, in
order to encourage certain broker-dealers to provide the Adviser with research
services which the Adviser anticipates will be useful to it.  Because the list
is merely a general guide, which is to be used only after the primary criterion
for the selection of broker-dealers (discussed above) has been met, substantial
deviations from the list are permissible and may be expected to occur.  In the
event any transactions are executed on an agency basis, the Adviser will
authorize the Funds to pay an amount of commission for effecting a securities
transaction in excess of the amount of commission another broker-dealer would
have charged only if the Adviser determines in good faith that such amount of
commission is reasonable in relation to the value of the brokerage and research
services provided by such broker-dealer,


                                      -17-

<PAGE>

viewed in terms of either that particular transaction or the Adviser's overall
responsibilities with respect to the accounts as to which it exercises
investment discretion.  If the Funds execute any transactions on an agency
basis, they will generally pay higher than the lowest commission rates
available.

     Any portfolio transactions for the Funds executed on an agency basis,
including transactions in futures contracts and options thereon, may be effected
through the Distributor.  In determining the commissions to be paid to the
Distributor in connection with transactions effected on a securities exchange,
it is the policy of the Funds that such commissions will, in the judgment of the
Adviser, subject to review by the Board of Directors, be both (a) at least as
favorable as those which would be charged by other qualified brokers or futures
commission merchants in connection with comparable transactions involving
similar securities being purchased or sold on an exchange during a comparable
period of time, and (b) at least as favorable as commissions contemporaneously
charged by the Distributor on comparable transactions for its most favored
comparable unaffiliated customers.  While the Funds do not deem it practicable
and in their best interest to solicit competitive bids for commission rates on
each transaction, consideration will regularly be given to posted commission
rates as well as to other information concerning the level of commissions
charged on comparable transactions by other qualified brokers and futures
commission merchants.

     For the fiscal year ended September 30, 1994, National Fund and Minnesota
Fund each paid $850 in brokerage commissions in connection with options and
futures transactions.  For the fiscal years ended September 30, 1995 and 1996,
neither Fund paid any brokerage commissions.

     From time to time the Funds may acquire the securities of their regular
brokers or dealers or parent companies of such brokers or dealers.  Neither Fund
purchased securities of its regular brokers or dealers or parent companies of
such brokers or dealers during the 1996 fiscal year.

                      CAPITAL STOCK AND OWNERSHIP OF SHARES

     The Board of Directors is empowered under the Company's Articles of
Incorporation to issue additional series of the Company's common stock without
shareholder approval.  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 the other series.

     The assets received by the Company 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, are 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


                                      -18-

<PAGE>

and with a share of the general expenses of the Company.  Any general expenses
of the Company 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 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
other series of the Company or any additional series created in the future.  All
classes of shares in a 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 a series, 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 a series.  This ability to create multiple classes
of shares within each series of the Company will allow the Company in the future
the flexibility to better tailor its methods of marketing, administering and
distributing shares of the Funds 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.

     As of November 22, 1996, no shareholder owns of record or was known by the
Funds to own beneficially 5% or more of the outstanding shares of either Fund.
The directors and officers of the Funds as a group owned less than 1% of the
outstanding shares of each Fund as of such date.

                    NET ASSET VALUE AND PUBLIC OFFERING PRICE

     The method for determining the public offering price of Fund shares is
summarized in the Prospectus in the text following the headings "How to Purchase
Shares--Purchase Price" and "Valuation of Shares."  The net asset value of each
Fund's shares is determined on each day on which the New York Stock Exchange is
open, provided that the net asset value need not be determined on days when no
Fund shares are tendered for redemption and no order for Fund shares is
received.  The New York Stock Exchange is not open for business on the following
holidays (or on the nearest Monday or Friday if the holiday falls on a weekend):
New Year's Day, Presidents' Day, Good Friday, Memorial Day, July 4th, Labor Day,
Thanksgiving and Christmas.

     The portfolio securities in which each Fund invests fluctuate in value, and
hence the net asset value per share of each Fund also fluctuates.  On
September 30, 1996, the net asset value per share for each Fund was calculated
as follows:

                                  NATIONAL FUND

     Net Assets ($45,934,895)                =    Net Asset Value Per Share
     ------------------------------               ($10.81)
     Shares Outstanding (4,247,615)


                                      -19-

<PAGE>

                                 MINNESOTA FUND

     Net Assets ($125,676,782)               =    Net Asset Value Per Share
     -------------------------------              ($10.89)
     Shares Outstanding (11,537,228)

     In each case, a sales charge of 4.17% of the net asset value (in the case
of sales of less than $100,000) will be added to the net asset value per share
to determine the public offering price per share.

                             PERFORMANCE COMPARISONS

     Advertisements and other sales literature for the Funds may refer to
"yield," "tax equivalent yield," "average annual total return" and "cumulative
total return."   Such amounts are calculated as follows:

     Yield is computed by dividing the net investment income per share (as
defined under Securities and Exchange Commission rules and regulations) earned
during the computation period by the maximum offering price per share on the
last day of the period, according to the following formula:
                                               6
                            YIELD = 2[(a-b + 1) - 1]
                                       ---
                                       cd

     Where:    a    =    dividends and interest earned during the period;
               b    =    expenses accrued for the period (net of
                         reimbursements);
               c    =    the average daily number of shares outstanding during
                         the period that were entitled to receive dividends; and
               d    =    the maximum offering price per share on the last day of
                         the period.

     National Fund's yield for the 30-day period ended September 30, 1996
was 5.03%.  For the same period, Minnesota Fund's yield was 5.11%.  Had the
Distributor not voluntarily waived a portion of its Rule 12b-1 fees, the 30-day
yield as of September 30, 1996 for National Fund and Minnesota Fund would have
been 4.93% and 5.02%, respectively.

     Tax equivalent yield is computed by dividing that portion of the yield of a
Fund (as computed pursuant to the above paragraph) which is tax-exempt by one
minus a stated income tax rate and adding the product to that portion, if any,
of the yield of the Fund that is not tax-exempt.

     National Fund's tax equivalent yield for the 30-day period ended
September 30, 1996 was 7.29%, assuming a federal income tax rate of 31%.  For
the same period, Minnesota Fund's tax equivalent yield was 8.46%, assuming a
combined federal/Minnesota income tax rate of 39.6%.  Had the Distributor not
voluntarily waived a portion of its Rule 12b-1 fees, the 30-day tax-equivalent
yield as of September 30, 1996 for National Fund and Minnesota Fund would have
been 7.14% and 8.31%, respectively.

     Average annual total return figures are computed by finding the average
annual compounded rates of return over the periods indicated in the
advertisement that would equate the initial amount invested to the ending
redeemable value, according to the following formula:

                                        n
                                  P(1+T) = ERV

     Where:    P    =    a hypothetical initial payment of $1,000;
               T    =    average annual total return;
               n    =    number of years; and
               ERV  =    ending redeemable value at the end of the period of a
                         hypothetical $1,000 payment made at the beginning of
                         such period.

This calculation deducts the maximum sales charge from the initial hypothetical
$1,000 investment, assumes all dividends and capital gains distributions are
reinvested at net asset value on the appropriate reinvestment dates as described
in the Prospectus, and includes all recurring fees, such as investment advisory
and management fees, charged to all shareholder accounts.

     During the periods for which average annual total return is calculated, the
Adviser waived or paid certain expenses of the Funds and/or the Distributor
voluntarily limited Rule 12b-1 fees, thereby increasing average annual total
return.  These expenses may or may not be waived or paid in the future, in the
Adviser's and the Distributor's discretion.

     The following table sets forth the average annual total return of each Fund
for various periods ended September 30, 1996:

               ERV  =    ending redeemable value at the end of the period of a
                         hypothetical $1,000 payment made at the beginning of
                         such period; and
               P    =    initial payment of $1,000

This calculation assumes all dividends and capital gain distributions are
reinvested at net asset value on the appropriate reinvestment dates as described
in the Prospectus and includes all recurring fees, such as investment advisory
and management fees, charged to all shareholder accounts.

     The cumulative total returns for the period from July 11, 1988
(commencement of operations) through September 30, 1996 for National Fund and
Minnesota Fund were 75.95% and 74.90%, respectively.  The Adviser waived or paid
certain expenses of the Funds and/or the Distributor voluntarily limited Rule
12b-1 fees during this time period and such expenses and fees may or may not be
waived or paid in the future.  Absent any voluntary fee waivers or expense
payments, National Fund's cumulative total return for the same period would have
been 72.22% and Minnesota Fund's cumulative total return would have been 72.35%.

     In addition to advertising total return and yield, comparative performance
information may be used from time to time in advertising the Funds' shares,
including data from Lipper Analytical Services, Inc. ("Lipper"), Morningstar,
other industry publications and other entities or organizations which track the
performance of investment companies.  The performance of each Fund may be
compared to that of its unmanaged benchmark index and to the performance of
similar funds as reported by Lipper.  Each Fund's benchmark index and comparison
group are set forth below.

     Performance information for the Funds also may be compared to other
unmanaged indices.  Unmanaged indices do not reflect deductions for
administrative and management costs and expenses.  The Funds may also include in
advertisements and communications to Fund shareholders evaluations of a Fund
published by nationally recognized ranking services and by financial
publications that are nationally recognized, such as BARRON'S, BUSINESS WEEK,
FORBES, INSTITUTIONAL INVESTOR, INVESTOR'S DAILY, MONEY, KIPLINGER'S PERSONAL
FINANCE MAGAZINE, MORNINGSTAR MUTUAL FUND VALUES, THE NEW YORK TIMES, USA TODAY
and THE WALL STREET JOURNAL.

     The performance of National Fund may be compared to the performance of the
General Municipal Bond Funds Average, as reported by Lipper, and to the
performance of the Lehman Brothers Municipal Index.  The performance of
Minnesota Fund may be compared to the performance of the Minnesota Municipal
Bond Funds Average, as reported by Lipper, and to the performance of the Lehman
Brothers Municipal Index.

                               PURCHASE OF SHARES

     An investor may qualify for a reduced sales charge immediately by signing a
nonbinding Letter of Intent stating the investor's intention to invest within a
13-month period, beginning not earlier than 90 days prior to the date of
execution of the Letter, a specified amount which, if made at one time, would
qualify for a reduced sales charge.  Reinvested dividends will be treated as
purchases of additional shares.  Any redemptions made during the term of the
Letter of Intent will be subtracted from the amount of purchases in determining
whether the Letter of Intent has been completed.  During the term of a Letter of
Intent, IFTC will hold shares representing 5% of the amount that the investor
intends to invest during the 13-month period in escrow for payment of a higher
sales charge if the full amount indicated in the Letter of Intent is not
purchased.  Dividends on the escrowed shares will be paid to the shareholder.
The escrowed shares will be released when the full amount indicated has been
purchased.  If the full indicated amount is not purchased within the 13-month
period, the investor will be required to pay, either in cash or by liquidating
escrowed shares, an amount equal to the difference in the dollar amount of sales
charge actually paid and the amount of sales charge the investor would have paid
on his or her aggregate purchases if the total of such purchases had been made
at a single time.

                              REDEMPTION OF SHARES

GENERAL

     Redemption of shares, or payment, may be suspended at times (a) when the
New York Stock Exchange is closed for other than customary weekend or holiday
closings, (b) when trading on said Exchange is restricted, (c) when an emergency
exists, as a result of which disposal by the Funds of securities owned by them
is not reasonably practicable, or it is not reasonably practicable for the Funds
fairly to determine the value of their net assets, or (d) during any other
period when the Securities and Exchange Commission, by order, so permits,
provided that applicable rules and regulations of the Securities and Exchange
Commission shall govern as to whether the conditions prescribed in (b) or (c)
exist.

     Shareholders who purchased shares through a broker-dealer other than the
Distributor may also redeem such shares by written request to IFTC at the
address set forth in the Prospectus.  To be considered in proper form, written
requests for redemption should indicate the dollar amount or number of shares to
be redeemed, refer to the shareholder's Fund account number, and give either a
social security or tax identification number.  The request should be signed in
exactly the same way the account is registered.  If there is more than one owner
of the shares, all owners must sign.  If shares to be redeemed have a value of
$10,000 or more or redemption proceeds are to be paid to someone other than the
shareholder at the shareholder's address of record, the signature(s) must be
guaranteed by an "eligible guarantor institution," which includes a commercial
bank that is a member of the Federal Deposit Insurance Corporation, a trust
company, a member firm of a domestic stock exchange, a savings association or a
credit union that is authorized by its charter to provide a signature guarantee.
IFTC may reject redemption instructions if the


                                      -23-

<PAGE>

guarantor is neither a member of nor a participant in a signature guarantee
program.  Signature guarantees by notaries public are not acceptable.  The
purpose of a signature guarantee is to protect shareholders against the
possibility of fraud.  Further documentation will be requested from
corporations, administrators, executors, personal representatives, trustees and
custodians.  Redemption requests given by facsimile will not be accepted.
Unless other instructions are given in proper form, a check for the proceeds of
the redemption will be sent to the shareholder's address of record.

REINSTATEMENT PRIVILEGE

     A shareholder who has redeemed shares of a Fund may reinvest all or part of
the redemption proceeds in shares of any Fund within 30 days without payment of
an additional sales charge.  The Distributor will refund to any shareholder a
pro rata amount of any contingent deferred sales charge paid by such shareholder
in connection with a redemption of Fund shares if and to the extent that the
redemption proceeds are reinvested within 30 days of such redemption in any
mutual fund managed by the Adviser.  Such refund will be based upon the ratio of
the net asset value of shares purchased in the reinvestment to the net asset
value of shares redeemed.  Reinvestments will be allowed at net asset value
without the payment of a front-end sales charge, irrespective of the amounts of
the reinvestment, but shall be subject to the same pro rata contingent deferred
sales charge that was applicable to the earlier investment; however, the period
during which the contingent deferred sales charge shall apply on the newly
issued shares shall be the period applicable to the redeemed shares extended by
the number of days between the redemption and the reinvestment dates
(inclusive).

SYSTEMATIC WITHDRAWAL PLAN

     To establish a Systematic Withdrawal Plan for any Fund and receive regular
periodic payments, an account must have a value of $5,000 or more.  A request to
establish a Systematic Withdrawal Plan must be submitted in writing to an
investor's Piper Jaffray Investment Executive or other broker-dealer.  There are
no service charges for maintenance; the minimum amount that may be withdrawn
each period is $100.  (This is merely the minimum amount allowed and should not
be interpreted as a recommended amount.)  The holder of a Systematic Withdrawal
Plan will have any income dividends and any capital gains distributions
reinvested in full and fractional shares at net asset value.  To provide funds
for payment, the appropriate Fund will redeem as many full and fractional shares
as necessary at the redemption price, which is net asset value.  Redemption of
shares may reduce or possibly exhaust the shares in your account, particularly
in the event of a market decline.  As with other redemptions, a redemption to
make a withdrawal payment is a sale for federal income tax purposes.  Payments
made pursuant to a Systematic Withdrawal Plan cannot be considered as actual
yield or income since part of such payments may be a return of capital.

     The maintenance of a Systematic Withdrawal Plan for a Fund concurrent with
purchases of additional shares of that Fund would be disadvantageous because of
the sales commission involved in the additional purchases.  A confirmation of


                                      -24-

<PAGE>

each transaction showing the sources of the payment and the share and cash
balance remaining in the account will be sent.  The plan may be terminated on
written notice by the shareholder or the appropriate Fund, and it will terminate
automatically if all shares are liquidated or withdrawn from the account or upon
the death or incapacity of the shareholder.  The amount and schedule of
withdrawal payments may be changed or suspended by giving written notice to your
Piper Jaffray Investment Executive or other broker-dealer at least seven
business days prior to the end of the month preceding a scheduled payment.

                                    TAXATION

     Pursuant to the Internal Revenue Code of 1986 (the "Code"), each Fund will
be subject to a nondeductible excise tax equal to 4% of the excess, if any, of
the amount required to be distributed pursuant to the Code for each calendar
year over the amount actually distributed.  In order to avoid the imposition of
this excise tax, each Fund generally must declare dividends by the end of a
calendar year representing 98% of the Fund's ordinary income for the calendar
year and 98% of its capital gain net income (both long-term and short-term
capital gains) for the 12-month period ending October 31 of the calendar year.

     Ordinarily, distributions and redemption proceeds earned by a Fund
shareholder are not subject to withholding of federal income tax.  However, 31%
of a Fund shareholder's distributions and redemption proceeds must be withheld
if a Fund shareholder fails to supply the Fund or its agent with such
shareholder's taxpayer identification number or if a Fund shareholder who is
otherwise exempt from withholding fails to properly document such shareholder's
status as an exempt recipient.

     Any loss on the sale or exchange of shares of a Fund generally will be
disallowed to the extent that a shareholder acquires or contracts to acquire
shares of the same Fund within 30 days before or after such sale or exchange.
In addition, if a shareholder disposes of shares within 90 days of acquiring
such shares and purchases other shares of the Company or another mutual fund
managed by the Adviser at a reduced sales charge, the shareholder's tax basis
for determining gain or loss on the shares which are disposed of is reduced by
the lesser of the amount of the sales charge that was paid when the shares
disposed of were acquired or the amount by which the sales charge for the new
shares is reduced.  If a shareholder's tax basis is so reduced, the amount of
the reduction is treated as part of the tax basis of the new shares.

     Any loss on the sale or exchange of shares of a Fund held for six months or
less (although regulations may reduce this time period to 31 days) will be
disallowed for federal and Minnesota income tax purposes to the extent of the
amount of any exempt-interest dividend received with respect to such shares.
This loss disallowance rule applies to Minnesota taxpayers (including
corporations) even though all or a portion of such dividend is not excluded from
Minnesota taxable income.  Certain deductions otherwise allowable to financial
institutions and property and casualty insurance companies will be eliminated or
reduced by reason of the receipt of certain exempt-interest dividends.


                                      -25-

<PAGE>

     Under the Code, interest on indebtedness incurred or continued to purchase
or carry shares of an investment company paying exempt-interest dividends, such
as each Fund, will not be deductible by a shareholder in proportion to the ratio
of exempt-interest dividends to all dividends other than those treated as
long-term capital gains.  Indebtedness may be allocated to shares of either Fund
even though not directly traceable to the purchase of such shares.  Federal law
also restricts the deductibility of other expenses allocable to shares of each
Fund.  Similar nondeductibility rules apply under Minnesota law to individuals,
estates and trusts, even as to exempt-interest dividends that are not excluded
from Minnesota taxable net income.

     For federal income tax purposes, an alternative minimum tax ("AMT") is
imposed on taxpayers to the extent that such tax exceeds a taxpayer's regular
income tax liability (with certain adjustments).  Exempt-interest dividends
attributable to interest income on certain tax-exempt obligations issued after
August 7, 1986 to finance certain private activities are treated as an item of
tax preference that is included in alternative minimum taxable income for
purposes of computing the federal alternative minimum tax for all taxpayers and
the federal environmental tax on corporations.  The Funds may invest in
obligations the interest on which is treated as an item of tax preference, to
the extent set forth in the Prospectus.  In addition, a portion of all other
tax-exempt interest received by a corporation, including exempt-interest
dividends, will be included in adjusted current earnings and earnings and
profits for purposes of determining the federal corporate alternative minimum
tax, the environmental tax imposed on corporations by Section 59A of the Code,
and the branch profits tax imposed on foreign corporations under Section 884 of
the Code.

     Because liability for AMT will depend upon the regular tax liability and
tax preference items of a specific taxpayer, the extent, if any, to which any
tax preference items resulting from investment in a Fund will be subject to the
tax will depend upon each shareholder's individual situation.  For shareholders
with substantial tax preferences, the AMT could reduce the after-tax economic
benefits of an investment in the Fund.  Each shareholder is advised to consult
his or her tax adviser with respect to the possible effects of such tax
preference items.

     For shareholders who are or may become recipients of Social Security
benefits, exempt-interest dividends are includable in computing "modified
adjusted gross income" for purposes of determining the amount of Social Security
benefits, if any, that is required to be included in gross income.  The maximum
amount of Social Security benefits includable in gross income is 85%.

     The Code also forbids a regulated investment company from earning 30% or
more of its gross income from the sale or other disposition of securities,
futures contracts and options held less than three months.

     The Code requires a regulated investment company to diversify its holdings.
The Internal Revenue Service has not made its position clear regarding the
treatment of futures contracts and options for purposes of the diversification
test,


                                      -26-

<PAGE>

and the extent to which a Fund could buy or sell futures contracts and options
may be limited by this requirement.

     Gain or loss on futures contracts and options is taken into account when
realized by entering into a closing transaction or by exercise.  In addition,
with respect to many types of futures contracts and options held at the end of a
Fund's taxable year, unrealized gain or loss on such contracts is taken into
account at the then current fair market value thereof under a special
"marked-to-market, 60/40 system," and such gain or loss is recognized for tax
purposes.  The gain or loss from such futures contracts and options (including
premiums on certain options that expire unexercised) is treated as 60% long-term
and 40% short-term capital gain or loss, regardless of their holding period.
The amount of any capital gain or loss actually realized by a Fund in a
subsequent sale or other disposition of such futures contracts will be adjusted
to reflect any capital gain or loss taken into account by the Fund in a prior
year as a result of the constructive sale under the "marked-to-
market, 60/40 system."  Notwithstanding the rules described above, with respect
to certain futures contracts, a Fund may make an election that will have the
effect of exempting all or a part of those identified futures contracts from
being treated for federal income tax purposes as sold on the last business day
of the Fund's taxable year.  All or part of any loss realized by the Fund on any
closing of a futures contract may be deferred until all of the Fund's offsetting
positions with respect to the futures contracts are closed.

     The foregoing relates only to federal and Minnesota income taxation.
Prospective shareholders should consult their tax advisers as to the possible
application of other state and local income tax laws to Fund distributions.

                               GENERAL INFORMATION

     Minnesota has enacted legislation which authorizes corporations to
eliminate or limit the personal liability of a director to the corporation or
its shareholders for monetary damages for breach of the fiduciary duty of "care"
(the duty to act with the care an ordinarily prudent person in a like position
would exercise under similar circumstances).  Minnesota law does not, however,
permit a corporation to eliminate or limit the liability of a director (a) for
any breach of the director's duty of "loyalty" to the corporation or its
shareholders (the duty to act in good faith and in a manner reasonably believed
to be in the best interest of the corporation), (b) for acts or omissions not in
good faith or that involve intentional misconduct or a knowing violation of law,
(c) for authorizing a dividend, stock repurchase or redemption or other
distribution in violation of Minnesota law or for violation of certain
provisions of Minnesota securities laws, or (d) for any transaction from which
the director derived an improper personal benefit.  Minnesota law does not
permit elimination or limitation of a director's liability under the 1933 Act or
the Securities Exchange Act of 1934, and the 1940 Act prohibits elimination or
limitation of a director's liability for acts involving willful malfeasance, bad
faith, gross negligence or reckless disregard of the duties of a director.  The
Articles of Incorporation of the Company limit the liability of directors to the
fullest extent permitted by Minnesota law and the 1940 Act.

                              FINANCIAL STATEMENTS

     The audited financial statements for the Funds as of September 30, 1996, as
set forth in the Fund's Annual Reports, are incorporated by reference into this
Statement of Additional Information.  The audited financial statements are
provided in reliance on the report of KPMG Peat Marwick LLP, 4200 Norwest
Center, Minneapolis, Minnesota 55402, independent auditors of the Funds, given
on the authority of such firm as experts in accounting and auditing.

                               PENDING LITIGATION

          Complaints have been brought in federal and state court relating to
one open-end and twelve closed-end investment companies managed by the Adviser
and to two open-end funds for which the Adviser has acted as sub-adviser.  On
February 13, 1996, a Settlement Agreement became effective for the consolidated
class action lawsuit, titled IN RE: PIPER FUNDS INC. INSTITUTIONAL GOVERNMENT
INCOME PORTFOLIO LITIGATION.   The Amended Consolidated Class Action Complaint
was filed on October 5, 1994, in the United States District Court, District of
Minnesota, against Institutional Government Income Portfolio (a series of Piper
Funds Inc.), the Adviser, the Distributor, William H. Ellis and Edward J.
Kohler, and had alleged the making of materially misleading statements in the
prospectus, common law negligent misrepresentation and breach of fiduciary duty.
The Settlement Agreement will provide approximately $67.5 million, together with
interest earned, less certain disbursements and attorney fees, to class members
in payments scheduled over approximately three years.  Such payments will be
made by Piper Jaffray Companies Inc. and the Adviser and will not be an
obligation of Piper Funds Inc.

     Two additional complaints relating to the Institutional Government Income
Portfolio remain pending.  These complaints were brought by investors who
requested exclusion from the settlement class and are based on claims similar to
those asserted in the consolidated Class Action complaint.  The first pending
complaint was brought on April 11, 1995, and filed in the Minnesota State
District Court, Hennepin County.  This action was removed to United States
District Court, District of Minnesota.  The plaintiff, Frank R. Berman, Trustee
of Frank R. Berman Professional CP Pension Plan Trust, sued individually and not
on behalf of any putative class.  Defendants are the Distributor, Piper Funds
Inc., Morton Silverman and Worth Bruntjen.  A second pending complaint relating
to the Institutional Government Income Portfolio was filed on June 22, 1995 in
the Montana Thirteenth Judicial District Court, Yellowstone County by Beverly
Muth against the Distributor and Teresa L. Darnielle.  In addition to the above
complaints, a number of actions have been commenced in arbitration by some of
individual investors who requested exclusion from the settlement class in the IN
RE: PIPER FUNDS INC. action.

     A complaint was filed by Herman D. Gordon on October 20, 1994, in the
United States District Court, District of Minnesota, against American Adjustable
Rate Term Trust Inc.--1998, American Adjustable Rate Term Trust Inc.--1999, the
Adviser, the Distributor, Piper Jaffray Companies Inc., Benjamin Rinkey, Jeffrey
Griffin, Charles N. Hayssen and Edward J. Kohler.  A second complaint was filed
by


                                      -28-

<PAGE>

Frank Donio, I.R.A. and other plaintiffs on April 14, 1995, in the United States
District Court, District of Minnesota, against American Adjustable Rate Term
Trust Inc.--1996, American Adjustable Rate Term Trust Inc.--1997, American
Adjustable Rate Term Trust Inc.--1998, American Adjustable Rate Term Trust
Inc.--1999, the Adviser, the Distributor, Piper Jaffray Companies Inc. and
certain associated individuals.  Plaintiffs in both actions filed a Consolidated
Amended Class Action Complaint on May 23, 1995 and by Order dated June 8, 1995,
the Court consolidated the two putative class actions.  The consolidated amended
complaint, which purports to be a class action, alleges certain violations of
federal and state securities laws, breach of fiduciary duty and negligent
misrepresentation.  On August 23, 1996, the Court granted final approval to the
parties' agreement to settle all outstanding cliams of the purported class
action. The Effective Date of the Settlement Agreement was September 23, 1996.
The Settlement Agreement provides for $14 million in principal payments
consisting of $500,000 which was paid upon the Court's preliminary approval,
$1.5 million which was paid on the Effective Date of the Settlement Agreement,
and payments of $3 million on each anniversary of the Effective Date for the
next four years, with accrued interest payments of up to $1.8 million.

     Two additional complaints relating to the American Adjustable Rate Term
Trusts, which are based on claims similar to those asserted in the Gordon/Donio
Consolidated Complaint, remain pending.  The first of these additional
complaints was filed against the Distributor on August 11, 1995 in Washington
State District Court, King County, by plaintiff Ernest Volinn.  The second
complaint was filed against the Distributor on November 1, 1995 in the United
States District Court, District of Idaho, by plaintiff Ewing Company Profit
Sharing Plan.  In addition to the above complaints, a number of actions have
been commenced in arbitration by individual investors in the American Adjustable
Rate Term Trusts.

     A complaint was filed by Gary E. Nelson on June 28, 1995 in the United
States District Court for the Western District of Washington at Seattle against
American Strategic Income Portfolio Inc. -- II ("BSP"), the Adviser, the
Distributor, Piper Jaffray Companies Inc., Worth Bruntjen, Charles N. Hayssen,
Michael Jansen, William H. Ellis and Edward J. Kohler.  A second complaint was
filed by the same individual in the same court on July 12, 1995 against American
Opportunity Income Fund Inc. ("OIF"), the Adviser, the Distributor, Piper
Jaffray Companies Inc., Worth Bruntjen, Charles N. Hayssen, Michael Jansen,
William H. Ellis and Edward J. Kohler.  On September 7, 1995, Christian
Fellowship Foundation Peace United Church of Christ, Gary E. Nelson and Lloyd
Schmidt filed an amended complaint purporting to be a class action in the United
States District Court for the District of Washington.  The complaint was filed
against American Government Income Portfolio, Inc. ("AAF"), American Government
Income Fund Inc. ("AGF"), American Government Term Trust, Inc., American
Strategic Income Portfolio Inc. ("ASP"), American Strategic Income Portfolio
Inc. -- II, American Strategic Income Portfolio Inc. -- III ("CSP"), American
Opportunity Income Fund Inc., American Select Portfolio Inc., Piper Jaffray
Companies Inc., the Distributor, the Adviser and certain associated individuals.
By Order filed October 5, 1995, the complaints were consolidated.  Plaintiffs
filed a second amended complaint on February 5, 1996 and a third amended
complaint on June 4, 1996.  The third amended third complaint


                                      -29-

<PAGE>

alleges generally that the prospectus and financial statements of each
investment company were false and misleading.  Specific violations of various
federal securities laws are alleged with respect to each investment company.
The complaint also alleges that the defendants violated the Racketeer Influenced
and Corrupt Organizations Act, the Washington State Securities Act and the
Washington Consumer Protection Act.  The named plaintiffs and defendants have
reached an agreement-in-principle on a proposed settlement.  If approved by the
Court, a settlement agreement consistent with the terms of the agreement-in-
principle would provide $15.5 million to class members in payments by Piper
Jaffray Companies Inc. and the Adviser over the next four years.  The settlement
also includes an agreement that each of OIF, AAF, and AGF would offer to
repurchase up to 25% of their outstanding shares from current shareholders at
net asset value.  If the discounts between net asset value and market price of
these funds do not decrease to 5% or less within approximately two years after
the effective date of the settlement, the fund boards may submit shareholder
proposals to convert these funds to an open-end format.  Finally, the agreement
stipulates that each of ASP, BSP, CSP and SLA would offer to repurchase up to
10% of their outstanding shares from current shareholders at net asset value.

     Four additional complaints are pending which involve the funds named as
defendants in the Nelson/Christian Fellowship Consolidated Action and are based
on claims similar to that action.  The first additional complaint was filed
against the Distributor and Richard Tallent in Montana State District Court,
Silver Bow County on November 1, 1995 by plaintiff John Darlington.  The second
complaint was filed against the Distributor and Richard Tallent on April 11,
1996 in Montana State District Court, Silver Bow County by plaintiff Kenneth
Schneider.  The third complaint was filed against the Distributor and Richard
Tallent on April 11, 1996 in Montana State District Court, Silver Bow County by
plaintiff Margaret Nagel.  The fourth complaint was filed against the
Distributor on August 7, 1996 by plaintiff Kenneth Gennerman as Trustee of the
Nicole Bowlin Trust in Wisconsin Circuit Court, Waukesha County.  In addition to
the above complaints, a number of arbitrations have been commenced by individual
investors in the funds named as defendants in the Nelson/Christian Fellowship
Consolidated Action.

     Complaints have also been filed relating to two open-end funds for which
the Adviser has acted as sub-adviser, Managers Intermediate Mortgage Fund and
Managers Short Government Fund.  A complaint was filed on September 26, 1994 in
the United States District Court, District of Connecticut, by Florence R. Hosea,
Bobby W. Hosea, Getrud B. Dale and Peter M. Dale, Andrew Poffel and Diane Poffel
as tenants by the Entireties, Myrone Sarone, Donna M. DiPalo, Bernard B. Geltner
and Gail Geltner and Paul Delman.  The complaint was filed against The Managers
Funds, The Managers Funds, L.P., Robert P. Watson, the Adviser, the Distributor,
an individual associated with the Adviser, Evaluation Associates, Inc. and
Managers Intermediate Mortgage Fund.  The complaint, which is a putative class
action, alleges certain violations of federal securities laws, including the
making of false and misleading statements in the prospectus, and alleges
negligent misrepresentation, breach of fiduciary duty and common law fraud.  A
similar complaint was filed as a putative class action in the same court on
November 4, 1994.  The complaint was filed by Karen E. Kopelman against The
Managers Fund,


                                      -30-

<PAGE>

The Managers Funds, L.P., Robert P. Watson, the Adviser, the Distributor, Worth
Bruntjen, Evaluation Associates, Inc. and Managers Intermediate Mortgage Fund.
The two putative class actions were consolidated by court order on December 13,
1994.  Plaintiffs filed an Amended and Restated Complaint on July 19, 1995.  A
complaint relating to the Managers Short Government Fund was filed on
November 18, 1994 in the United States District Court, District of Minnesota.
The complaint was filed by Robert Fleck as a putative class action against The
Managers Funds, The Managers Funds, L.P., the Adviser, the Distributor, Worth
Bruntjen, Evaluation Associates, Inc., Robert P. Watson, John E. Rosati, William
M. Graulty, Madeline H. McWhinney, Steven J. Pasggioli, Thomas R. Schneeweis and
Managers Short Government Fund, F/K/A/ Managers Short Government Income Fund.
The complaint alleges certain violations of federal securities laws, including
the making of false and misleading statements in the prospectus, and negligent
misrepresentation.  The named plaintiff and defendants have reached an
agreement-in-principle on a proposed settlement.  If approved by the Court and a
sufficiently large percentage of the putative class members, a settlement
agreement consistent with the terms of the agreement-in-principle would provide
to class members up to a total of $1.5 million collectively from The Managers
Funds, L.P. and the Adviser on the effective date of the settlement.  A third
complaint relating to both the Managers Intermediate Mortgage Fund and the
Managers Short Government Fund was filed on October 26, 1995 in Connecticut
State Superior Court, Stamford/Norwalk District.  The complaint was filed by
First Commercial Trust Company, N.A. against the Managers Funds, Managers Short
Government Fund, Managers Intermediate Mortgage Fund, Managers Short and

                              RATINGS OF TAX-EXEMPT
                         SECURITIES AND COMMERCIAL PAPER

     The four highest ratings of Moody's Investors Service, Inc. ("Moody's") for
tax exempt securities are Aaa, Aa, A and Baa.  Tax exempt securities rated Aaa
are judged to be of the "best quality."  The rating of Aa is assigned to tax
exempt securities which are of "high quality by all standards," but as to which
margins of protection or other elements make long term risks appear somewhat
larger than Aaa rated tax exempt securities.  The Aaa and Aa rated tax exempt
securities comprise what are generally known as "high grade bonds."  Tax exempt
securities which are rated A by Moody's possess many favorable investment
attributes and are considered "upper medium grade obligations."  Factors giving
security to principal and interest of A rated tax exempt securities are
considered adequate, but elements may be present which suggest a susceptibility
to impairment sometime in the future.  Tax exempt securities rated Baa are
considered as "medium grade" obligations.  They are neither highly protected nor
poorly secured.  Interest payments and principal security appear adequate for
the present but certain protective elements may be lacking or may be
characteristically unreliable over any great length of time.  Such tax exempt
securities lack outstanding investment characteristics and in fact have
speculative characteristics as well.  Those securities in the A and Baa groups
which Moody's believes possess the strongest investment attributes are
designated by the symbols A 1 and Baa 1.  Other A and Baa securities comprise
the balance of their respective groups.  These rankings (1) designate the
securities which offer the maximum in security within their quality group, (2)
designate securities which can be bought for possible upgrading in quality and
(3) additionally afford the investor an opportunity to gauge more precisely the
relative attractiveness of offerings in the market place.

     Moody's ratings for state and municipal notes and other short-term loans
are designated Moody's Investment Grade (MIG).  This distinction is in
recognition of the differences between short-term credit risk and long-term
risk.  Factors affecting the liquidity of the borrower and short-term cyclical
elements are critical in short-term ratings, while other factors of major
importance in bond risk may be less important over the short run.  A short-term
rating may also be assigned on an issue having a demand feature.  Such ratings
will be designated as VMIG if the demand feature is rated.  Short-term ratings
on issues with demand features are differentiated to reflect such
characteristics as payment upon periodic demand rather than fixed maturity dates
and payment relying on external liquidity.  Loans bearing the MIG-1 or VMIG-1
designation are of the best quality, enjoying strong protection from established
cash flows of funds for their servicing or from established and broad-based
access to the market for refinancing, or both.  Loans bearing the MIG-2 or
VMIG-2 designation are of high quality, with margins of protection ample
although not so large as in the preceding group.  Loans bearing the MIG-3 or
VMIG-3 and MIG-4 or VMIG-4 designations are of lower quality.

     The four highest ratings of Standard & Poor's Ratings Services ("Standard &
Poor's") for tax exempt securities are AAA, AA, A and BBB.  Tax exempt
securities rated AAA bear the highest rating assigned by Standard & Poor's to a
debt obligation and indicates an extremely strong capacity to pay principal and
interest.  Tax exempt


                                       A-1

<PAGE>

securities rated AA also qualify as high-quality debt obligations.  Capacity to
pay principal and interest is very strong, and in the majority of instances they
differ from AAA issues only in small degree.  Securities rated A have a strong
capacity to pay principal and interest, although they are somewhat more
susceptible to the adverse effects of changes in circumstances and economic
conditions.  The BBB rating, which is the lowest "investment grade" security
rating by Standard & Poor's, indicates an adequate capacity to pay principal and
interest.  Whereas they normally exhibit adequate protection parameters, adverse
economic conditions or changing circumstances are more likely to lead to a
weakened capacity to pay principal and interest for securities in this category
than for securities in the A category.

     A Standard & Poor's note rating reflects the liquidity concerns and market
access risks unique to notes.  Notes due in three years or less will likely
receive a note rating.  Notes maturing beyond three years will most likely
receive a long-term debt rating.  The designation SP-1 indicates a very strong
or strong capacity to pay principal and interest.  The designation SP-2
indicates a satisfactory capacity to pay principal and interest.

     Commercial paper ratings are graded by Standard & Poor's into four
categories, ranging from "A" for the highest quality obligations to "D" for the
lowest.  Issues assigned the A rating are regarded as having the greatest
capacity for timely payment.  Issues in this category are further refined with
designation 1, 2, and 3 to indicate the relative degree of safety.  The "A-1"
designation indicates that the degree of safety regarding timely payment is very
strong.  Those issues determined to possess overwhelming safety characteristics
will be denoted with a plus sign designation.  The "A-2" designation indicates
that the degree of safety regarding timely payment is strong.

     Moody's commercial paper ratings are opinions of the ability of the issuers
to repay punctually promissory obligations not having an original maturity in
excess of nine months.  Moody's makes no representation that such obligations
are exempt from registration under the Securities Act of 1933, nor does it
represent that any specific note is a valid obligation of a rated issuer or
issued in conformity with any applicable law.  Moody's employs the following
three designations, all judged to be investment grade, to indicate the relative
repayment capacity of rated issuers:

     Prime-1                       Superior capacity for repayment of short-term
                                   promissory obligations.

     Prime-2                       Strong capacity for repayment of short-term
                                   promissory obligations.

     Prime-3                       Acceptable capacity for repayment of
                                   short-term promissory obligations.

                                   APPENDIX B
                          FUTURES CONTRACTS AND OPTIONS

FUTURES CONTRACTS

     Each Fund may purchase and sell interest rate futures contracts and options
thereon.  An interest rate futures contract creates an obligation on the part of
the seller (the "short") to deliver, and an offsetting obligation on the part of
the purchaser (the "long") to accept delivery of, the type of financial
instrument called for in the contract in a specified delivery month for a stated
price.  A majority of transactions in interest rate futures contracts, however,
do not result in the actual delivery of the underlying instrument, but are
settled through liquidation, i.e., by entering into an offsetting transaction.
The futures contracts to be traded by the Fund are traded only on commodity
exchanges--known as "contract markets"--approved for such trading by the
Commodity Futures Trading Commission ("CFTC"), and must be executed through a
futures commission merchant, or brokerage firm, which is a member of the
relevant contract market.  These contract markets, through their clearing
corporations, guarantee that the contracts will be performed.  Presently,
interest rate futures contracts are based on such debt securities as long-term
U.S. Treasury Bonds, Treasury Notes, Government National Mortgage Association
modified pass-through mortgage-backed securities, three-month U.S. Treasury
Bills and bank certificates of deposit.

     Although most interest rate futures contracts by their terms call for
actual delivery or acceptance of commodities or securities, in most cases the
contracts are closed out before the settlement date without the making or taking
of delivery.  Closing out a short position is effected by purchasing a futures
contract for the same aggregate amount of the specific type of financial
instrument or commodity and the same delivery month.  If the price of the
initial sale of the futures contract exceeds the price of the offsetting
purchase, the seller is paid the difference and realizes a gain.  Conversely, if
the price of the offsetting purchase exceeds the price of the initial sale, the
trader realizes a loss.  Similarly, the closing out of a long position is
effected by the purchaser entering into a futures contract sale.  If the
offsetting sale price exceeds the purchase price, the purchaser realizes a gain,
and if the purchase price exceeds the offsetting sale price, he realizes a loss.

     The purchase or sale of a futures contract differs from the purchase or
sale of a security, in that no price or premium is paid or received.  Instead,
an amount of cash or securities acceptable to the Adviser and the relevant
contract market, which varies, but is generally about 5% of the contract amount,
must be deposited with the custodian in the name of the broker.  This amount is
known as "initial margin," and represents a "good faith" deposit assuring the
performance of both the purchaser and the seller under the futures contract.
Subsequent payments to and from the broker, known as "variation margin," are
required to be made on a daily basis as the price of the futures contract
fluctuates, making the long or short positions in the futures contract more or
less valuable, a process known as "marking


                                       B-1

<PAGE>

to the market."  Prior to the settlement date of the futures contract, the
position may be closed out by taking an opposite position which will operate to
terminate the position in the futures contract.  A final determination of
variation margin is then made, additional cash is required to be paid to or
released by the broker, and the purchaser realizes a loss or gain.  In addition,
a commission is paid on each completed purchase and sale transaction.

     Each Fund also may purchase and sell futures contracts on an index of
municipal securities.  These instruments provide for the purchase or sale of a
hypothetical portfolio of municipal bonds at a fixed price in a stated delivery
month.  Unlike most other futures contracts, however, a municipal bond index
futures contract does not require actual delivery of securities, but results in
a cash settlement based upon the difference in value of the index between the
time the contract was entered into and the time it is liquidated.

     The municipal bond index underlying these futures contracts is The Bond
Buyer Municipal Bond Index, developed by THE BOND BUYER and the Chicago Board of
Trade ("CBT"), the contract market on which the futures contracts are traded.
The index is comprised of 40 tax-exempt term municipal revenue and general
obligation bonds.  Each bond included in the index must be rated A- or higher by
Standard and Poor's or A or higher by Moody's and must have a remaining maturity
of 19 years or more.  Twice a month new issues satisfying the eligibility
requirements are added to, and an equal number of old issues are deleted from,
the index.  The value of the index is computed daily according to a formula
based upon the price of each bond in the index, as evaluated by four
dealer-to-dealer brokers.

     The municipal bond index futures contract is traded only on the CBT.  Like
other contract markets, the CBT assures performance under futures contracts
through a clearing corporation, a nonprofit organization managed by the exchange
membership which is also responsible for handling daily accounting of deposits
or withdrawals of margin.

     The purpose of the acquisition or sale of futures contracts by the Funds,
as holders of long-term municipal securities, is to hedge against fluctuations
in rates on such securities without actually buying or selling long-term
municipal securities.  For example, if a Fund owns long-term bonds and interest
rates are expected to increase, the Fund might sell futures contracts.  Such a
sale would have much the same effect as selling some of the long-term bonds in
the Fund's portfolio.  If interest rates increase as anticipated by the Adviser,
the value of certain long-term securities in the portfolio would decline, but
the value of the Fund's futures contracts would increase at approximately the
same rate, thereby keeping the net asset value of the Fund from declining as
much as it otherwise would have.  Of course, since the value of the securities
in each Fund's portfolio will far exceed the value of the futures contracts sold
by such Fund, an increase in the value of the futures contracts could only
mitigate--but not totally offset--the decline in the value of the portfolio.


                                       B-2

<PAGE>

     Similarly, when it is expected that interest rates may decline, futures
contracts could be purchased to hedge against a Fund's anticipated purchases of
long-term bonds at higher prices.  Since the rate of fluctuation in the value of
futures contracts should be similar to that of long-term bonds, the Fund could
take advantage of the anticipated rise in the value of long-term bonds without
actually buying them until the market had stabilized.  At that time, the futures
contracts could be liquidated and the Fund's cash could then be used to buy
long-term bonds on the cash market.  The Fund could accomplish similar results
by selling bonds with long maturities and investing in bonds with short
maturities when interest rates are expected to increase or by buying bonds with
long maturities and selling bonds with short maturities when interest rates are
expected to decline.  However, in circumstances when the market for bonds may
not be as liquid as that for futures contracts, the ability to invest in such
contracts could enable a Fund to react more quickly to anticipated changes in
market conditions or interest rates.

OPTIONS ON FUTURES CONTRACTS

     The Funds may purchase and sell put and call options on interest rate and
municipal bond index futures contracts which are traded on a United States
exchange or board of trade as a hedge against changes in interest rates, and
will enter into closing transactions with respect to such options to terminate
existing positions.  Options on interest rate futures contracts are currently
available with respect to Treasury bonds (direct obligations of the U.S.
Treasury which generally have maturities of greater than ten years).  An options
contract based on the municipal bond index futures contract discussed above was
introduced on the CBT in June 1987.  An option on a futures contract, as
contrasted with the direct investment in such a contract, gives the purchaser
the right, in return for the premium paid, to assume a position in a futures
contract at a specified exercise price at any time prior to the expiration date
of the option.  Options on futures contracts are similar to options on
securities, which give the purchaser the right, in return for the premium paid,
to purchase or sell securities.  A call option gives the purchaser of such
option the right to buy, and obliges its writer to sell, a specified underlying
futures contract at a stated exercise price at any time prior to the expiration
date of the option.  A purchaser of a put option has the right to sell, and the
writer has the obligation to buy, such contract at the exercise price during the
option period.  Upon exercise of an option, the delivery of the futures position
by the writer of the option to the holder of the option will be accompanied by
delivery of the accumulated balance in the writer's futures margin account,
which represents the amount by which the market price of the futures contract
exceeds, in the case of a call, or is less than, in the case of a put, the
exercise price of the option on the futures contract.  If an option is exercised
on the last trading day prior to the expiration date of the option, the
settlement will be made entirely in cash equal to the difference between the
exercise price of the option and the closing price of the interest rate futures
contract on the expiration date.  The potential loss related to the purchase of
an option on a futures contract is limited to the premium paid for the option
(plus transaction costs).  Because the value of the option is fixed at the point
of sale, there are no daily cash


                                       B-3

<PAGE>

payments to reflect changes in the value of the underlying contract; however,
the value of the option does change daily and that change would be reflected in
the net asset values of the Funds.  In connection with the writing of options on
futures contracts, a Fund will make initial margin deposits and make or receive
maintenance margin payments that reflect changes in the market value of such
options.  Premiums received from the writing of an option are included in
initial margin deposits.

     PURCHASE OF PUT OPTIONS ON FUTURES CONTRACTS.  A Fund will purchase put
options on futures contracts if the Adviser anticipates a rise in interest
rates.  Because the value of an interest rate or municipal bond index futures
contract moves inversely in relation to changes in interest rates, a put option
on such a contract becomes more valuable as interest rates rise.  By purchasing
put options on futures contracts at a time when the Adviser expects interest
rates to rise, a Fund will seek to realize a profit to offset the loss in value
of its portfolio securities.

     PURCHASE OF CALL OPTIONS ON FUTURES CONTRACTS.  A Fund will purchase call
options on futures contracts if the Adviser anticipates a decline in interest
rates.  The purchase of a call option on an interest rate or municipal bond
index futures contract represents a means of obtaining temporary exposure to
market appreciation at limited risk.  Because the value of an interest rate or
municipal bond index futures contract moves inversely in relation to changes to
interest rates, a call option on such a contract becomes more valuable as
interest rates decline.  A Fund will purchase a call option on a futures
contract to hedge against a decline in interest rates in a market advance when
the Fund is holding cash.  The Fund can take advantage of the anticipated rise
in the value of long-term securities without actually buying them until the
market is stabilized.  At that time, the options can be liquidated and the
Fund's cash can be used to buy long-term securities.

     WRITING CALL OPTIONS ON FUTURES CONTRACTS.  A Fund will write call options
on futures contracts if the Adviser anticipates a rise in interest rates.  As
interest rates rise, a call option on such a contract becomes less valuable.  If
the futures contract price at expiration of the option is below the exercise
price, the option will not be exercised and the Fund will retain the full amount
of the option premium.  Such amount provides a partial hedge against any decline
that may have occurred in the Fund's portfolio securities.

     WRITING PUT OPTIONS ON FUTURES CONTRACTS.  A Fund will write put options on
futures contracts if the Adviser anticipates a decline in interest rates.  As
interest rates decline, a put option on an interest rate or municipal bond index
futures contract becomes less valuable.  If the futures contract price at
expiration of the option has risen due to declining interest rates and is above
the exercise price, the option will not be exercised and the Fund will retain
the full amount of the option premium.  Such amount can then be used by the Fund
to buy long-term securities when the market has stabilized.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

     HEDGING RISKS IN FUTURES CONTRACTS TRANSACTIONS.  There are several risks
in using municipal bond index or interest rate futures contracts as hedging
devices.  One risk arises because the prices of futures contracts may not
correlate perfectly with movements in the underlying municipal bond index or
fixed-income security due to certain market distortions.  First, all
participants in the futures market are subject to initial margin and variation
margin requirements.  Rather than making additional variation margin payments,
investors may close the contracts through offsetting transactions which could
distort the normal relationship between the index or security and the futures
market.  Second, the margin requirements in the futures market are lower than
margin requirements in the securities market, and as a result the futures market
may attract more speculators than does the securities market.  Increased
participation by speculators in the futures market may also cause temporary
price distortions.  Because of possible price distortion in the futures market
and because of imperfect correlation between movements in the municipal bond
index or securities and movements in the prices of futures contracts, even a
correct forecast of general market trends may not result in a successful hedging
transaction over a very short period.

     Another risk arises because of imperfect correlation between movements in
the value of the futures contracts and movements in the value of securities
subject to the hedge.  For example, there can be no assurance that there will be
a correlation between movements in the price of the municipal bond index and
movements in the price of the municipal bonds which are the subject of the
hedge.  The degree of imperfection or correlation depends upon, among other
things, the differences between the municipal securities being hedged and the
municipal securities underlying the municipal bond index futures contracts.  For
example, each bond included in the municipal bond index must have a remaining
maturity of 19 years or more, whereas each Fund's portfolio probably will be
comprised of securities with an average aggregate maturity of less than 19
years.  This risk of an imperfect correlation increases to the extent that
either Fund enters into futures contracts for other than municipal bonds since
the value of municipal bonds and other debt securities may not react exactly the
same to general changes in interest rates and may react differently to factors
other than changes in the general level of interest rates.

     Successful use of futures contracts by a Fund is subject to the ability of
the Adviser to predict correctly movements in the direction of interest rates.
If a Fund has hedged against the possibility of an increase in interest rates
adversely affecting the value of fixed-income securities held in its portfolio
and interest rates decrease instead, the Fund will lose part or all of the
benefit of the increased value of its security which it has hedged because it
will have offsetting losses in its futures positions.  In addition, in such
situations, if the Fund has insufficient cash, it may have to sell securities to
meet daily variation margin requirements.  Such sales of securities may, but
will not necessarily, be at increased prices which reflect the


                                       B-5

<PAGE>

decline in interest rates.  The Fund may have to sell securities at a time when
it may be disadvantageous to do so.

     LIQUIDITY OF FUTURES CONTRACTS.  A Fund may elect to close some or all of
its contracts prior to expiration.  The purpose of making such a move would be
to reduce or eliminate the hedge position held by the Fund.  A Fund may close
its positions by taking opposite positions.  Final determinations of variation
margin are then made, additional cash as required is paid by or to the Fund, and
the Fund realizes a loss or a gain.

     Positions in futures contracts may be closed only on an exchange or board
of trade providing a secondary market for such futures contracts.  Although the
Funds intend to enter into futures contracts only on exchanges or boards of
trade where there appears to be an active secondary market, there is no
assurance that a liquid secondary market will exist for any particular contract
at any particular time.  The purchase of municipal bond index futures contracts
involves an additional risk since these are instruments with a relatively short
trading history.  As a result, it is possible that trading in such futures
contracts will be less liquid than that in other futures contracts.

     In addition, most domestic futures exchanges and boards of trade limit the
amount of fluctuation permitted in futures contract prices during a single
trading day.  The daily limit establishes the maximum amount that the price of a
futures contract may vary either up or down from the previous day's settlement
price at the end of a trading session.  Once the daily limit has been reached in
a particular contract, no trades may be made that day at a price beyond that
limit.  The daily limit governs only price movement during a particular trading
day and therefore does not limit potential losses because the limit may prevent
the liquidation of unfavorable positions.  It is possible that futures contract
prices could move to the daily limit for several consecutive trading days with
little or no trading, thereby preventing prompt liquidation of futures positions
and subjecting some futures traders to substantial losses.  In such event, it
will not be possible to close a futures position and, in the event of adverse
price movements, the Fund would be required to make daily cash payments of
variation margin.  In such circumstances, an increase in the value of the
portion of the portfolio being hedged, if any, may partially or completely
offset losses on the futures contract.  However, as described above, there is no
guarantee that the price of the securities being hedged will, in fact, correlate
with the price movements in the futures contract and thus provide an offset to
losses on a futures contract.

     RISKS OF OPTIONS ON FUTURES CONTRACTS.  The use of options on futures
contracts also involves certain risks.  Compared to the purchase or sale of
futures contracts, the purchase of call or put options on futures contracts
involves less potential risk to a Fund because the maximum amount at risk is the
premium paid for the options (plus transactions costs).  The writing of a call
option on a futures contract generates a premium which may partially offset a
decline in the value of a


                                       B-6

<PAGE>

Fund's portfolio assets.  By writing a call option, the Fund becomes obligated
to sell a futures contract, which may have a value higher than the exercise
price.  Conversely, the writing of a put option on a futures contract generates
a premium, but the Fund becomes obligated to purchase a futures contract, which
may have a value lower than the exercise price.  Thus, the loss incurred by a
Fund in writing options on futures contracts may exceed the amount of the
premium received.

     The effective use of options strategies is dependent, among other things,
on a Fund's ability to terminate options positions at a time when the Adviser
deems it desirable to do so.  Although a Fund will enter into an option position
only if the Adviser believes that a liquid secondary market exists for such
option, there is no assurance that the Fund will be able to effect closing
transactions at any particular time or at an acceptable price.  The Funds'
transactions involving options on futures contracts will be conducted only on
recognized exchanges.

     A Fund's purchase or sale of put or call options on futures contracts will
be based upon predictions as to anticipated interest rates by the Adviser, which
could prove to be inaccurate.  Even if the expectations of the Adviser are
correct, there may be an imperfect correlation between the change in the value
of the options and of the Fund's portfolio securities.

REGULATORY MATTERS

     To the extent required to comply with applicable Securities and Exchange
Commission releases and staff positions, when entering into futures contracts,
the Fund will maintain, in a segregated account, cash or liquid high-grade debt
securities equal to the value of such contracts.

     The Commodity Futures Trading Commission (the "CFTC"), a Federal agency,
regulates trading activity on the exchanges pursuant to the Commodity Exchange
Act, as amended.  The CFTC requires the registration of "commodity pool
operators," defined as any person engaged in a business which is of the nature
of an Company, syndicate, or a similar form of enterprise, and who, in
connection therewith, solicits, accepts, or receives from others, funds,
securities, or property for the purpose of trading in any commodity for future
delivery on or subject to the rules of any contract market.  The CFTC has
adopted Rule 4.5, which provides an exclusion from the definition of commodity
pool operator for any registered investment company which meets the requirements
of the Rule.  Rule 4.5 requires, among other things, that an investment company
wishing to avoid commodity pool operator status use futures and options
positions only (a) for "bona fide hedging purposes" (as defined in CFTC
regulations) or (b) for other purposes so long as aggregate initial margins and
premiums required in connection with non-hedging positions do not exceed 5% of
the liquidation value of the investment company's portfolio.


                                       B-7

<PAGE>

Any investment company wishing to claim the exclusion provided in Rule 4.5 must
file a notice of eligibility with both the CFTC and the National Futures
Association.  Both Funds intend to file such a notice and to meet the
requirements of Rule 4.5, or such other requirements as the CFTC or its staff
may from time to time issue, in order to render registration as a commodity pool
operator unnecessary.

     No person is directly or indirectly controlled by or under common control
with the Registrant.

ITEM 26.  NUMBER OF HOLDERS OF SECURITIES

     As of November 21, 1996:                       Number of
                              Title of Class      Record Holders

Minnesota Tax-Exempt Fund     Common Shares            2,734

ITEM 27.  INDEMNIFICATION

     The Articles of Incorporation and Bylaws of the Registrant provide that the
Registrant shall indemnify such persons for such expenses and liabilities, in
such manner and under such circumstances, to the full extent permitted by
Section 302A.521, Minnesota Statutes, as now enacted or hereafter amended,
provided that no such indemnification may be made if it would be in violation of
Section 17(h) of the Investment Company Act of 1940, as now enacted or hereafter
amended.  Section 302A.521 of the Minnesota Statutes, as now enacted, provides
that a corporation shall indemnify a person made or threatened to be made a
party to a proceeding of the person against judgments, penalties, fines,
settlements, and reasonable expenses, including attorneys' fees and
disbursements, incurred by the person in connection with the proceeding if, with
respect to the acts or omissions of the person complained of in the proceeding,
the person has not been indemnified by another organization for the same
judgments, penalties, fines, settlements, and reasonable expenses incurred by
the person in connection with the proceeding with respect to the same acts or
omissions; acted in good faith, received no improper personal benefit and the
Minnesota Statutes dealing with directors' conflicts of interest, if applicable,
have been satisfied; in the case of a criminal proceeding, had no reasonable
cause to believe that the conduct was unlawful; and reasonably believed that the
conduct was in the best interests of the corporation or, in certain
circumstances, reasonably believed that the conduct was not opposed to the best
interests of the corporation.

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


                                        2

<PAGE>

is against public policy as expressed in the Act and will be governed by the
final adjudication of such issue.
