waivers and absorptions, as described above. PLEASE REMEMBER THAT THE EXAMPLE
SHOULD NOT BE CONSIDERED AS REPRESENTATIVE OF PAST OR FUTURE EXPENSES AND THAT
ACTUAL EXPENSES MAY BE HIGHER OR LOWER THAN THOSE SHOWN. The assumption in the
Example of a 5% annual return is required by regulations of the SEC applicable
to all mutual funds. The assumed 5% annual return is not a prediction of, and
does not represent, the projected or actual performance of the Fund's shares.
 
                       INVESTMENT OBJECTIVES AND POLICIES
 
   The Fund's risk and return potential depends in part on the maturity and
credit-quality characteristics of the underlying investments in its portfolio.
In general, longer-maturity fixed-income securities carry higher yields and
greater price volatility than shorter-term fixed-income securities. Similarly,
fixed income securities issued by less-creditworthy entities tend to carry
higher yields than those with higher credit ratings. (See "Fundamentals of Fixed
Income Investing" for a more detailed discussion of the principles and risks
associated with fixed income securities.)
   The Fund has adopted certain fundamental investment restrictions that are set
forth in its Statement of Additional Information ("SAI"). Those restrictions,
the Fund's investment objective, and any other investment policies identified as
"fundamental" cannot be changed without shareholder approval. To further guide
investment activities, the Fund has also instituted a number of non-fundamental
operating policies, which are described throughout this Prospectus and in the
SAI. Although operating policies may be changed by the Fund's Board of Directors
without shareholder approval, the Fund will promptly notify shareholders of any
material change in operating policies.

STRONG SHORT-TERM HIGH-YIELD BOND FUND
 
   The Fund seeks total return by investing for a high level of current income
with a moderate degree of share-price fluctuation.
   The Fund is designed for investors who want to pursue higher income than
higher-quality debt obligations generally provide and who are willing to accept
the risk of principal fluctuation associated with medium- and lower-quality debt
obligations. BECAUSE ITS SHARE PRICE WILL VARY, THE FUND IS NOT AN APPROPRIATE
INVESTMENT FOR THOSE WHOSE PRIMARY OBJECTIVE IS ABSOLUTE PRINCIPAL STABILITY.
   The Fund invests primarily in short- and intermediate-term,
non-investment-grade debt obligations. Under normal market conditions, at least
65% of the Fund's total assets will be invested in non-investment-grade debt
obligations. The Fund intends to invest at least 80% of its net assets in debt
obligations rated B or above by Standard & Poor's Rating Group ("S&P") or other
nationally recognized statistical rating organizations ("NRSROs"). The Fund's
average portfolio maturity will be between one and three years under normal
market conditions.
   Medium-quality debt obligations are those in the fourth-highest category
(e.g., bonds rated BBB by S&P) or obligations determined by the Advisor to be of
comparable quality. Medium-quality debt obligations, although considered
investment grade, have some speculative characteristics. Lower-quality bonds,
also commonly referred to as "non-investment-grade" bonds or "junk" bonds, are
those rated below the fourth-highest category (e.g., BB to C by S&P) or bonds of
comparable quality. See "Fundamentals of Fixed Income Investing - Credit Quality
- - High-Yield (High-Risk) Securities" for further information on the risks
associated with investing in medium- and lower-quality debt obligations.)
   When the Advisor determines market conditions warrant a temporary defensive
position, the Fund may invest without limitation in cash and short-term
fixed-income securities as well as investment-grade debt obligations.
 
                                FUNDAMENTALS OF
                             FIXED INCOME INVESTING
 
   The Fund may invest in a wide variety of debt obligations and other
securities. (See "Implementation of Policies and Risks - Debt Obligations.")
   Issuers of debt obligations have a contractual obligation to pay interest at
a specified rate ("coupon rate") on specified dates and to repay principal
("face value" or "par value") on a specified maturity date. Certain debt
obligations (usually intermediate- and long-term obligations) have provisions
that allow the issuer to redeem or "call" the obligation before its maturity.
Issuers are most likely to call such debt obligations during periods of falling
interest rates. As a result, the Fund may be required to invest the
unanticipated proceeds of
 
                             ---------------------
 
                               PROSPECTUS PAGE I-5
<PAGE>   9
 
the called obligations at lower interest rates, which may cause the Fund's
income to decline.
   Although the net asset values of the Fund is expected to fluctuate, the
Advisor actively manages the Fund's portfolio and adjusts its average portfolio
maturity according to the Advisor's interest rate outlook while seeking to avoid
or reduce, to the extent possible, any negative changes in net asset value.
 
PRICE VOLATILITY
 
   The market value of debt obligations is affected by changes in prevailing
interest rates. The market value of a debt obligation generally reacts inversely
to interest-rate changes, meaning, when prevailing interest rates decline, an
obligation's price usually rises, and when prevailing interest rates rise, an
obligation's price usually declines. A fund portfolio consisting primarily of
debt obligations will react similarly to changes in interest rates.
 
MATURITY
 
   In general, the longer the maturity of a debt obligation, the higher its
yield and the greater its sensitivity to changes in interest rates. Conversely,
the shorter the maturity, the lower the yield but the greater the price
stability. Commercial paper is generally considered the shortest form of debt
obligation. Notes, whose original maturities are two years or less, are
considered short-term obligations. The term "bond" generally refers to
securities with maturities longer than two years. Bonds with maturities of three
years or less are considered short-term, bonds with maturities between three and
seven years are considered intermediate-term, and bonds with maturities greater
than seven years are considered long-term.
 
CREDIT QUALITY
 
   The values of debt obligations may also be affected by changes in the credit
rating or financial condition of their issuers. Generally, the lower the quality
rating of an obligation, the higher the degree of risk as to the payment of
interest and return of principal. To compensate investors for taking on such
increased risk, those issuers deemed to be less-creditworthy generally must
offer their investors higher interest rates than do issuers with better credit
ratings.
   In conducting its credit research and analysis, the Advisor considers both
qualitative and quantitative factors to evaluate the creditworthiness of
individual issuers. The Advisor also relies, in part, on credit ratings compiled
by a number of NRSROs, which include Standard & Poor's Ratings Group ("S&P),
Moody's Investors Service, Inc., Fitch Investors Service, Inc., Duff & Phelps
Rating Co., Thomson BankWatch, Inc., and IBCA, Inc. "Appendix - Ratings of Debt
Obligations" presents a summary of the ratings of these organizations.
 
                             ---------------------

<PAGE>   10
 
Please refer to the Appendix in the Funds' SAI for a more detailed description
of the ratings of the NRSROs.
 
   INVESTMENT-GRADE DEBT OBLIGATIONS. Debt obligations rated in the highest-
through the medium-quality categories are commonly referred to as
"investment-grade" debt obligations and include the following:
 
- - U.S. government securities (See "Implementation of Policies and Risks - Debt
  Obligations" below);
- - bonds or bank obligations rated in one of the four highest rating categories
  (e.g., BBB or higher by S&P);
- - short-term notes rated in one of the two highest rating categories (e.g., SP-2
  or higher by S&P);
- - short-term bank obligations rated in one of the three highest rating
  categories (e.g., A-3 or higher by S&P), with respect to obligations maturing
  in one year or less;
- - commercial paper rated in one of the three highest rating categories (e.g.,
  A-3 or higher by S&P);
- - unrated debt obligations determined by the Advisor to be of comparable
  quality; and
- - repurchase agreements involving investment-grade debt obligations.
 
   Investment-grade debt obligations are generally believed to have relatively
low degrees of credit risk. All ratings are determined at the time of
investment. Any subsequent rating downgrade of a debt obligation will be
monitored by the Advisor to consider what action, if any, the Fund should take
consistent with its investment objective. For purposes of determining whether a
security is investment grade, the Advisor may use the highest rating assigned to
that security by any NRSRO.
 
   HIGH-YIELD (HIGH-RISK) SECURITIES. High-yield (high-risk) securities, also
referred to as "junk bonds," are those securities that are rated lower than
investment grade and unrated securities of comparable quality. Although these
securities generally offer higher yields than investment-grade securities with
similar maturities, lower-quality securities involve greater risks, including
the possibility of default or bankruptcy. In general, they are regarded to be
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal. Other potential risks associated with investing in high-
yield securities include:
 
- - substantial market-price volatility resulting from changes in interest rates,
  changes in or uncertainty about economic conditions, and changes in the actual
  or perceived ability of the issuer to meet its obligations;
- - greater sensitivity of highly-leveraged issuers to adverse economic changes
  and individual-issuer developments;
- - subordination to the prior claims of other creditors;
 
                             ---------------------
 
                               PROSPECTUS PAGE I-7
<PAGE>   11
 
- - additional Congressional attempts to restrict the use or limit the tax and
  other advantages of these securities; and
- - adverse publicity and changing investor perceptions about these securities.
 
   As with any other asset in the Fund's portfolio, any reduction in the value
of such securities as a result of the factors listed above would be reflected in
the net asset value of the Fund. In addition, the Fund that invests in
lower-quality securities may incur additional expenses to the extent it is
required to seek recovery upon a default in the payment of principal and
interest on its holdings. As a result of the associated risks, successful
investments in high-yield, high-risk securities will be more dependent on the
Advisor's credit analysis than generally would be the case with investments in
investment-grade securities.
   It is uncertain how the high-yield market will perform during a prolonged
period of rising interest rates. A prolonged economic downturn or a prolonged
period of rising interest rates could adversely affect the market for these
securities, increase their volatility, and reduce their value and liquidity. In
addition, lower-quality securities tend to be less liquid than higher-quality
debt securities because the market for them is not as broad or active. If market
quotations are not available, these securities will be valued in accordance with
procedures established by the Fund's Board of Directors. Judgment may,
therefore, play a greater role in valuing these securities. The lack of a liquid
secondary market may have an adverse effect on market price and the Fund's
ability to sell particular securities.
 
                      IMPLEMENTATION OF POLICIES AND RISKS
 
   In addition to the investment policies described above (and subject to
certain restrictions described below), the Fund may invest in some or all of the
following securities and may employ some or all of the following investment
techniques, some of which may present special risks as described below. A more
complete discussion of certain of these securities and investment techniques and
the associated risks is contained in the Fund's SAI.
 
DEBT OBLIGATIONS
 
   The Fund may invest in any debt obligations. The Fund's authority to invest
in certain types of debt obligations may be restricted or subject to objective
investment criteria. For additional information on these restrictions, see
"Investment Objectives and Policies."
 
   TYPES OF OBLIGATIONS. Debt obligations include (i) corporate debt securities,
including bonds, debentures, and notes; (ii) bank obligations, such as
certificates of deposit, banker's acceptances, and time deposits of domestic and
foreign banks and their subsidiaries and branches, and domestic savings and loan
associations (in amounts in excess of the insurance coverage
 
                             ---------------------
 
                               PROSPECTUS PAGE I-8
<PAGE>   12
 
(currently $100,000 per account) provided by the Federal Deposit Insurance
Corporation); (iii) commercial paper (including variable-amount master demand
notes); (iv) repurchase agreements; (v) loan interests; (vi) foreign debt
obligations issued by foreign issuers traded either in foreign markets or in
domestic markets through depositary receipts; (vii) convertible securities -
debt obligations of corporations convertible into or exchangeable for equity
securities or debt obligations that carry with them the right to acquire equity
securities, as evidenced by warrants attached to such securities, or acquired as
part of units of the securities; (viii) preferred stocks - securities that
represent an ownership interest in a corporation and that give the owner a prior
claim over common stock on the company's earnings or assets; (ix) trust
preferred securities - certain obligations which have characteristics of both
debt and preferred stock; (x) U.S. government securities; (xi) mortgage-backed
securities, collateralized mortgage obligations, and similar securities; and
(xii) municipal obligations.
 
GOVERNMENT SECURITIES
 
   U.S. government securities are issued or guaranteed by the U.S. government or
its agencies or instrumentalities. Securities issued by the government include
U.S. Treasury obligations, such as Treasury bills, notes, and bonds. Securities
issued or guaranteed by government agencies or instrumentalities include the
following:
 
- - the Federal Housing Administration, Farmers Home Administration, Export-Import
  Bank of the United States, Small Business Administration, and the Government
  National Mortgage Association, including GNMA pass-through certificates, whose
  securities are supported by the full faith and credit of the United States;
- - the Federal Home Loan Banks, Federal Intermediate Credit Banks, and the
  Tennessee Valley Authority, whose securities are supported by the right of the
  agency to borrow from the U.S. Treasury;
- - the Federal National Mortgage Association, whose securities are supported by
  the discretionary authority of the U.S. government to purchase certain
  obligations of the agency or instrumentality; and
- - the Student Loan Marketing Association, the Interamerican Development Bank,
  and International Bank for Reconstruction and Development, whose securities
  are supported only by the credit of such agencies.
 
   Although the U.S. government provides financial support to such U.S.
government-sponsored agencies or instrumentalities, no assurance can be given
that it will always do so. The U.S. government and its agencies and
instrumentalities do not guarantee the market value of their securities;
consequently, the value of such securities will fluctuate.
 
                             ---------------------
 
                               PROSPECTUS PAGE I-9
<PAGE>   13
 
MORTGAGE- AND ASSET-BACKED SECURITIES
 
   Mortgage-backed securities represent direct or indirect participation in, or
are secured by and payable from, mortgage loans secured by real property, and
include single- and multi-class pass-through securities and collateralized
mortgage obligations. Such securities may be issued or guaranteed by U.S.
government agencies or instrumentalities or by private issuers, generally
originators in mortgage loans, including savings associations, mortgage bankers,
commercial banks, investment bankers, and special purpose entities
(collectively, "private lenders"). Mortgage-backed securities issued by private
lenders may be supported by pools of mortgage loans or other mortgage-backed
securities that are guaranteed, directly or indirectly, by the U.S. government
or one of its agencies or instrumentalities, or they may be issued without any
governmental guarantee of the underlying mortgage assets but with some form of
non-governmental credit enhancement.
   Asset-backed securities have structural characteristics similar to mortgage-
backed securities. However, the underlying assets are not first-lien mortgage
loans or interests therein; rather they include assets such as motor vehicle
installment sales contracts, other installment loan contracts, home equity
loans, leases of various types of property and receivables from credit card or
other revolving credit arrangements. Payments or distributions of principal and
interest on asset-backed securities may be supported by non-governmental credit
enhancements similar to those utilized in connection with mortgage-backed
securities.
   The yield characteristics of mortgage- and asset-backed securities differ
from those of traditional debt obligations. Among the principal differences are
that interest and principal payments are made more frequently on mortgage-and
asset-backed securities, usually monthly, and that principal may be prepaid at
any time because the underlying mortgage loans or other assets generally may be
prepaid at any time. As a result, if the Fund purchases these securities at a
premium, a prepayment rate that is faster than expected will reduce yield to
maturity, while a prepayment rate that is slower than expected will have the
opposite effect of increasing the yield to maturity. Conversely, if the Fund
purchases these securities at a discount, a prepayment rate that is faster than
expected will increase yield to maturity, while a prepayment rate that is slower
than expected will reduce yield to maturity. Accelerated prepayments on
securities purchased by the Fund at a premium also impose a risk of loss of
principal because the premium may not have been fully amortized at the time the
principal is prepaid in full. The market for privately issued mortgage- and
asset-backed securities is smaller and less liquid than the market for
government sponsored mortgage-backed securities.
   The Fund may invest in stripped mortgage- or asset-backed securities, which
receive differing proportions of the interest and principal payments from the
underlying assets. The market value of such securities generally is more
sensitive to changes in prepayment and interest rates than is the case
 
                             ----------------------
 
                              PROSPECTUS PAGE I-10
<PAGE>   14
 
with traditional mortgage- and asset-backed securities, and in some cases the
market value may be extremely volatile. With respect to certain stripped
securities, such as interest-only ("IO") and principal-only ("PO") classes, a
rate of prepayment that is faster or slower than anticipated may result in the
Fund failing to recover all or a portion of its investment, even though the
securities are rated investment grade.
 
LOAN INTERESTS
 
   The Fund may invest a portion of its assets in loan interests, which are
interests in amounts owed by a corporate, governmental or other borrower to
lenders or lending syndicates. Loan interests purchased by the Fund may have a
maturity of any number of days or years, and may be secured or unsecured. Loan
interests, which may take the form of participation interests in, assignments
of, or novations of a loan, may be acquired from U.S. and foreign banks,
insurance companies, finance companies or other financial institutions that have
made loans or are members of a lending syndicate or from the holders of loan
interests. Loan interests involve the risk of loss in case of default or
bankruptcy of the borrower and, in the case of participation interests, involve
a risk of insolvency of the agent lending bank or other financial intermediary.
Loan interests are not rated by any NRSROs and are, at present, not readily
marketable and may be subject to contractual restrictions on resale.
 
FOREIGN SECURITIES AND CURRENCIES
 
   The Fund may invest up to 25% of its net assets directly or indirectly in
foreign securities. The Funds may invest in U.S. securities enhanced as to
credit quality or liquidity by foreign issuers without regard to this limit.
Foreign investments involve special risks, including:
 
- - expropriation, confiscatory taxation, and withholding taxes on dividends and
  interest;
- - less extensive regulation of foreign brokers, securities markets, and issuers;
- - less publicly available information and different accounting standards;
- - costs incurred in conversions between currencies, possible delays in
  settlement in foreign securities markets, limitations on the use or transfer
  of assets (including suspension of the ability to transfer currency from a
  given country), and difficulty of enforcing obligations in other countries;
  and
- - diplomatic developments and political or social instability.
 
   Foreign economies may differ favorably or unfavorably from the U.S. economy
in various respects, including growth of gross domestic product, rates of
inflation, currency depreciation, capital reinvestment, resource
self-sufficiency, and balance-of-payments positions. Many foreign securities may
be less liquid and their prices more volatile than comparable U.S. securities.
Although the
 
                             ----------------------
 
                              PROSPECTUS PAGE I-11
<PAGE>   15
 
Fund generally invests only in securities that are regularly traded on
recognized exchanges or in over-the-counter markets, from time to time foreign
securities may be difficult to liquidate rapidly without adverse price effects.
Certain costs attributable to foreign investing, such as custody charges and
brokerage costs, may be higher than those attributable to domestic investing.
   Because most foreign securities are denominated in non-U.S. currencies, the
investment performance of the Fund could be affected by changes in foreign
currency exchange rates to some extent. The value of the Fund's assets
denominated in foreign currencies will increase or decrease in response to
fluctuations in the value of those foreign currencies relative to the U.S.
dollar. Currency exchange rates can be volatile at times in response to supply
and demand in the currency exchange markets, international balances of payments,
governmental intervention, speculation, and other political and economic
conditions.
   The Fund may purchase and sell foreign currency on a spot basis and may
engage in forward currency contracts, currency options, and futures transactions
for hedging or any other lawful purpose. (See "Derivative Instruments.")
 
REPURCHASE AGREEMENTS
 
   The Fund may enter into repurchase agreements with certain banks and non-bank
dealers. In a repurchase agreement, the Fund buys a security at one price, and
at the time of sale, the seller agrees to repurchase the obligation at a
mutually agreed upon time and price (usually within seven days). The repurchase
agreement determines the yield during the purchaser's holding period, while the
seller's obligation to repurchase is secured by the value of the underlying
security. The Fund may enter into repurchase agreements with respect to any
security in which it may invest. The Advisor will monitor, on an ongoing basis,
the value of the underlying securities to ensure that the value always equals or
exceeds the repurchase price plus accrued interest. Repurchase agreements could
involve certain risks in the event of a default or insolvency of the other party
to the agreement, including possible delays or restrictions upon the Fund's
ability to dispose of the underlying securities. Although no definitive
creditworthiness criteria are used, the Advisor reviews the creditworthiness of
the banks and non-bank dealers with which the Fund enters into repurchase
agreements to evaluate those risks. The Fund may, under certain circumstances,
deem repurchase agreements collateralized by U.S. government securities to be
investments in U.S. government securities.
 
DERIVATIVE INSTRUMENTS
 
   The Fund may use derivative instruments for any lawful purpose consistent
with the Fund's investment objective such as hedging or managing risk.
Derivative instruments are commonly defined to include securities or contracts
whose values depend on (or "derive" from) the value of one or more other
 
                             ----------------------
 
                              PROSPECTUS PAGE I-12
<PAGE>   16
 
assets, such as securities, currencies, or commodities. These "other assets" are
commonly referred to as "underlying assets."
   A derivative instrument generally consists of, is based upon, or exhibits
characteristics similar to options or forward contracts. Options and forward
contracts are considered to be the basic "building blocks" of derivatives. For
example, forward-based derivatives include forward contracts, swap contracts, as
well as exchange-traded futures. Option-based derivatives include privately
negotiated, over-the-counter (OTC) options (including caps, floors, collars, and
options on forward and swap contracts) and exchange-traded options on futures.
Diverse types of derivatives may be created by combining options or forward
contracts in different ways, and by applying these structures to a wide range of
underlying assets.
   An option is a contract in which the "holder" (the buyer) pays a certain
amount (the "premium") to the "writer" (the seller) to obtain the right, but not
the obligation, to buy from the writer (in a "call") or sell to the writer (in a
"put") a specific asset at an agreed upon price at or before a certain time. The
holder pays the premium at inception and has no further financial obligation.
The holder of an option-based derivative generally will benefit from favorable
movements in the price of the underlying asset but is not exposed to
corresponding losses due to adverse movements in the value of the underlying
asset. The writer of an option-based derivative generally will receive fees or
premiums but generally is exposed to losses due to changes in the value of the
underlying asset.
   A forward is a sales contract between a buyer (holding the "long" position)
and a seller (holding the "short" position) for an asset with delivery deferred
until a future date. The buyer agrees to pay a fixed price at the agreed future
date and the seller agrees to deliver the asset. The seller hopes that the
market price on the delivery date is less than the agreed upon price, while the
buyer hopes for the contrary. The change in value of a forward-based derivative
generally is roughly proportional to the change in value of the underlying
asset.
   Derivative instruments may include (i) options; (ii) futures; (iii) options
on futures; (iv) short sales against the box, in which the Fund sells a security
it owns for delivery at a future date; (v) swaps, in which two parties agree to
exchange a series of cash flows in the future, such as interest-rate payments;
(vi) interest-rate caps, under which, in return for a premium, one party agrees
to make payments to the other to the extent that interest rates exceed a
specified rate, or "cap"; (vii) interest-rate floors, under which, in return for
a premium, one party agrees to make payments to the other to the extent that
interest rates fall below a specified level, or "floor"; (viii) forward currency
contracts and foreign currency exchange-related securities; and (ix) structured
instruments which combine the foregoing in different ways.
   Derivatives may be exchange-traded or traded in OTC transactions between
private parties. OTC transactions are subject to additional risks, such as the
credit risk of the counterparty to the instrument and are less liquid than
exchange-traded derivatives since they often can only be closed out with the
 
                             ----------------------
 
                              PROSPECTUS PAGE I-13
<PAGE>   17
 
other party to the transaction. Derivative instruments may include elements of
leverage and, accordingly, the fluctuation of the value of the derivative
instrument in relation to the underlying asset may be magnified. When required
by SEC guidelines, the Fund will set aside permissible liquid assets in a
segregated account to secure its obligations under the derivative.
   The successful use of derivatives by the Fund is dependent upon a variety of
factors, particularly the Advisor's ability to correctly anticipate trends in
the underlying asset. In a hedging transaction, if the Advisor incorrectly
anticipates trends in the underlying asset, the Fund may be in a worse position
than if no hedging had occurred. In addition, there may be imperfect correlation
between the Fund's derivative transactions and the instruments being hedged. To
the extent that the Fund is engaging in derivative transactions for risk
management, the Fund's successful use of such transactions is more dependent
upon the Advisor's ability to correctly anticipate such trends, since losses in
these transactions may not be offset by gains in the Fund's portfolio or by
lower purchase prices for assets it intends to acquire. The Advisor's prediction
of trends in underlying assets may prove to be inaccurate, which could result in
substantial losses to the Fund.
   In addition to the derivative instruments and strategies described above, the
Advisor expects to discover additional derivative instruments and other trading
techniques. The Advisor may utilize these new derivative instruments and
techniques to the extent that they are consistent with the Fund's investment
objective and permitted by the Fund's investment limitations, operating
policies, and applicable regulatory authorities.
 
WHEN-ISSUED SECURITIES
 
   The Fund may invest in securities purchased on a when-issued or delayed-
delivery basis. Although the payment and interest terms of these securities are
established at the time the purchaser enters into the commitment, these
securities may be delivered and paid for at a future date, generally within 45
days. Purchasing when-issued securities allows the Fund to lock in a fixed price
or yield on a security it intends to purchase. However, when the Fund purchases
a when-issued security, it immediately assumes the risk of ownership, including
the risk of price fluctuation.
   The greater the Fund's outstanding commitments for these securities, the
greater the exposure to potential fluctuations in the net asset value of the
Fund. Purchasing when-issued securities may involve the additional risk that the
yield available in the market when the delivery occurs may be higher or the
market price lower than that obtained at the time of commitment. Although the
Fund may be able to sell these securities prior to the delivery date, it will
purchase when-issued securities for the purpose of actually acquiring the
securities, unless, after entering into the commitment, a sale appears desirable
for investment reasons. When required by SEC guidelines, the Fund will set
 
                             ----------------------
 
                              PROSPECTUS PAGE I-14
<PAGE>   18
 
aside permissible liquid assets in a segregated account to secure its
outstanding commitments for when-issued securities.
 
ILLIQUID SECURITIES
 
   The Fund may invest up to 15% of its net assets in illiquid securities.
Illiquid securities are those securities that are not readily marketable,
including restricted securities and repurchase obligations maturing in more than
seven days. Certain restricted securities which may be resold to institutional
investors under Rule 144A under the Securities Act of 1933 and Section 4(2)
commercial paper may be determined to be liquid under guidelines adopted by each
Fund's Board of Directors.
 
ZERO-COUPON, STEP-COUPON, AND PAY-IN-KIND SECURITIES
 
   The Fund may invest in zero-coupon, step-coupon, and pay-in-kind securities.
These securities are debt securities that do not make regular cash interest
payments. Zero-coupon and step-coupon securities are sold at a deep discount to
their face value. Pay-in-kind securities pay interest through the issuance of
additional securities. Because such securities do not pay current cash income,
the price of these securities can be volatile when interest rates fluctuate.
While these securities do not pay current cash income, federal income tax law
requires the holders of zero-coupon, step-coupon, and pay-in-kind securities to
include in income each year the portion of the original issue discount (or
deemed discount) and other non-cash income on such securities accrued during
that year. In order to continue to qualify for treatment as a "regulated
investment company" under the Internal Revenue Code and avoid a certain excise
tax, the Fund may be required to distribute a portion of such discount and
income and may be required to dispose of other portfolio securities, which may
occur in periods of adverse market prices, in order to generate cash to meet
these distribution requirements.
 
MORTGAGE DOLLAR ROLLS AND
REVERSE REPURCHASE AGREEMENTS
 
   The Fund may engage in reverse repurchase agreements to facilitate portfolio
liquidity, a practice common in the mutual fund industry, or for arbitrage
transactions discussed below. In a reverse repurchase agreement, the Fund would
sell a security and enter into an agreement to repurchase the security at a
specified future date and price. The Fund generally retains the right to
interest and principal payments on the security. Since the Fund receives cash
upon entering into a reverse repurchase agreement, it may be considered a
borrowing. When required by SEC guidelines, the Fund will set aside permissible
liquid assets in a segregated account to secure its obligation to repurchase the
security.
 
                             ----------------------
 
                              PROSPECTUS PAGE I-15
<PAGE>   19
 
   The Fund may also enter into mortgage dollar rolls, in which the Fund would
sell mortgage-backed securities for delivery in the current month and
simultaneously contract to purchase substantially similar securities on a
specified future date. While the Fund would forego principal and interest paid
on the mortgage-backed securities during the roll period, the Fund would be
compensated by the difference between the current sale price and the lower price
for the future purchase as well as by any interest earned on the proceeds of the
initial sale. The Fund also could be compensated through the receipt of fee
income equivalent to a lower forward price. When required by SEC guidelines, the
Fund would set aside permissible liquid assets in a segregated account to secure
its obligation for the forward commitment to buy mortgage-backed securities.
Mortgage dollar roll transactions may be considered a borrowing by the Fund.
   The mortgage dollar rolls and reverse repurchase agreements entered into by
the Fund may be used as arbitrage transactions in which the Fund will maintain
an offsetting position in investment-grade debt obligations or repurchase
agreements that mature on or before the settlement date of the related mortgage
dollar roll or reverse repurchase agreement. Since the Fund will receive
interest on the securities or repurchase agreements in which it invests the
transaction proceeds, such transactions may involve leverage. However, since
such securities or repurchase agreements will be high quality and will mature on
or before the settlement date of the mortgage dollar roll or reverse repurchase
agreement, the Advisor believes that such arbitrage transactions do not present
the risks to the Fund that are associated with other types of leverage.
 
PORTFOLIO TURNOVER
 
   The annual portfolio turnover rate indicates changes in the Fund's portfolio.
The turnover rate may vary from year to year, as well as within a year. It may
also be affected by sales of portfolio securities necessary to meet cash
requirements for redemption of shares. High portfolio turnover in any year will
result in the payment by the Fund of above-average amounts of transaction costs
and could result in the payment by shareholders of above-average amounts of
taxes on realized investment gains. The annual portfolio turnover rates for the
Fund is expected to be between 200% and 300%. However, the Fund's portfolio
turnover rate may exceed 300% when the Advisor believes the anticipated benefits
of short-term investments outweigh any increase in transaction costs or increase
in capital gains.
 
CASH MANAGEMENT
 
   The Fund may invest directly in cash and short-term fixed-income securities,
including, for this purpose, shares of one or more money market funds managed by
the Advisor (collectively, the "Strong Money Funds"). The Strong Money Funds
seek current income, a stable share price of $1.00, and daily
 
                             ----------------------
 
                              PROSPECTUS PAGE I-16
<PAGE>   20
 
liquidity. All money market instruments can change in value when interest rates
or an issuer's creditworthiness change dramatically. The Strong Money Funds
cannot guarantee that they will always be able to maintain a stable net asset
value of $1.00 per share.
 
                                 ABOUT THE FUND
 
MANAGEMENT
 
   The Board of Directors of the Fund is responsible for managing its business
and affairs. The Fund has entered into an investment advisory agreement with
Strong Capital Management, Inc. (the "Advisor"). Under the terms of the
agreement, the Advisor manages the Fund's investments and business affairs
subject to the supervision of the Fund's Board of Directors.
 
   ADVISOR. The Advisor began conducting business in 1974. Since then, its
principal business has been providing continuous investment supervision for
individuals and institutional accounts, such as pension funds and profit-sharing
plans, as well as mutual funds, several of which are funding vehicles for
variable insurance products. As of  _______________ , the Advisor had over $__
billion under management. The Advisor's principal mailing address is P.O. Box
2936, Milwaukee, Wisconsin 53201. Mr. Richard S. Strong, the Chairman of the
Board of the Fund, is the controlling shareholder of the Advisor.
   As compensation for its services, the Fund pays the Advisor a monthly
management fee based on a percentage of each Fund's average daily net asset
value. The annual rate is .625% of the Fund's average daily net asset value.
From time to time, the Advisor may voluntarily waive all or a portion of its
management fee and/or absorb certain Fund expenses without further notification
of the commencement or termination of such waiver or absorption. Any such waiver
or absorption will temporarily lower the Fund's overall expense ratio and
increase the Fund's overall return to investors.
   Except for expenses assumed by the Advisor or Strong Funds Distributors,
Inc., the Fund is responsible for all its other expenses, including, without
limitation, interest charges, taxes, brokerage commissions, and similar
expenses; expenses of issue, sale, repurchase, or redemption of shares; expenses
or registering or qualifying shares for sale with the states and the SEC;
expenses of printing and distribution of prospectuses to existing shareholders;
charges of custodians (including fees as custodian for keeping books and similar
services for the Fund), transfer agents (including the printing and mailing of
reports and notices to shareholders), registrars, auditing and legal services,
and clerical services related to recordkeeping and shareholder relations;
printing of stock certificates; fees for directors who are not "interested
persons" of the Advisor; expenses of indemnification; extraordinary expenses;
and costs of shareholder and director meetings.
 
                             ----------------------
 
                              PROSPECTUS PAGE I-17
<PAGE>   21
 
   The Advisor permits portfolio managers and other persons who may have access
to information about the purchase or sale of securities in the Fund's portfolio
("access persons") to purchase and sell securities for their own accounts,
subject to the Advisor's policy governing personal investing. The policy
requires access persons to conduct their personal investment activities in a
manner that the Advisor believes is not detrimental to the Fund or to the
Advisor's other advisory clients. Among other things, the policy requires access
persons to obtain preclearance before executing personal trades and prohibits
access persons from keeping profits derived from the purchase or sale of the
same security within 60 calendar days. See the SAI for more information.
 
   PORTFOLIO MANAGER. Mr. Jeffrey A. Koch joined the Advisor as a portfolio
manager and securities analyst in June 1989. For a brief period prior to that,
he was a market-maker clerk at Fossett Corporation, a clearing firm. Mr. Koch
earned his M.B.A. in Finance at Washington University in St. Louis, Missouri in
1989. His undergraduate degree, awarded in 1987, is from the University of
Minnesota-Morris. Mr. Koch is also a Chartered Financial Analyst. He has managed
the Fund since its inception in ______ 1997.
 
TRANSFER AND DIVIDEND-DISBURSING AGENT
 
   The Advisor, P.O. Box 2936, Milwaukee, Wisconsin 53201, also acts as
dividend-disbursing agent and transfer agent for the Fund. The Advisor is
compensated for its services based on an annual fee per account plus certain
out-of-pocket expenses. The fees received and the services provided as transfer
agent and dividend-disbursing agent are in addition to those received and
provided under the Advisory Agreements between the Advisor and the Fund.
 
DISTRIBUTOR
 
   Strong Funds Distributors, Inc., P.O. Box 2936, Milwaukee, Wisconsin 53201,
an indirect subsidiary of the Advisor, acts as distributor of the shares of the
Fund.
 
ORGANIZATION
 
   SHAREHOLDER RIGHTS. The Fund is a series of common stock of Strong Income
Funds, Inc., a Wisconsin corporation that is authorized to issue an indefinite
number of shares of common stock and series and classes of series of shares of
common stock. Each share of the Fund has one vote, and all shares participate
equally in dividends and other capital gains distributions by the respective
Fund and in the residual assets of the Fund in the event of liquidation.
Certificates will be issued for shares held in your account only upon your
written request. You will, however, have full shareholder rights
 
                             ----------------------
 
                              PROSPECTUS PAGE I-18
<PAGE>   22
 
whether or not you request certificates. Generally, the Fund will not hold an
annual meeting of shareholders unless required by the Investment Company Act of
1940 (the "1940 Act").
 
   SHAREHOLDER PRIVILEGES. The shareholders of the Fund may benefit from the
privileges described in the "Shareholder Manual" (see page II-1). However, the
Fund reserves the right, at any time and without prior notice, to suspend,
limit, modify, or terminate any of these privileges or their use in any manner
by any person or class.
 
DISTRIBUTIONS AND TAXES
 
   PAYMENT OF DIVIDENDS AND OTHER DISTRIBUTIONS. Unless you choose otherwise,
all your dividends and capital gains distributions will be automatically
reinvested in additional Fund shares. Or, you may elect to have all your
dividends and capital gain distributions from the Fund automatically invested in
additional shares of another Strong Fund. Shares are purchased at the net asset
value determined on the payment date. If you request in writing that your
dividends and other distributions be paid in cash, the Fund will credit your
bank account by Electronic Funds Transfer ("EFT") or issue a check to you within
five business days of the payment date. You may change your election at any time
by calling or writing Strong Funds. Strong Funds must receive any such change 7
days (15 days for EFT) prior to a dividend or capital gain distribution payment
date in order for the change to be effective for that payment.
   The policy of the Fund is to pay dividends from net investment income monthly
and to distribute substantially all net realized capital gains, and gains from
foreign currency transactions, if any, annually. The Fund may make additional
distributions if necessary to avoid imposition of a 4% excise tax on
undistributed income and gains. The Fund declares dividends on each day its net
asset value is calculated, except for bank holidays. Income earned on weekends,
holidays (including bank holidays), and days on which net asset value is not
calculated is declared as a dividend on the day on which the Fund's net asset
value was most recently calculated.
 
   TAX STATUS OF DIVIDENDS AND OTHER DISTRIBUTIONS. You will be subject to
federal income tax at ordinary income tax rates on any dividends you receive
that are derived from investment company taxable income (consisting generally of
net investment income, net short-term capital gain, and net gains from certain
foreign currency transactions, if any). Distributions by the Funds of net
capital gain (the excess of net long-term capital gain over net short-term
capital loss), when designated as such, are taxable to you as long-term capital
gains, regardless of how long you have held your Fund shares.
 
                             ----------------------
 
                              PROSPECTUS PAGE I-19
<PAGE>   23
 
   The Fund's distributions are taxable in the year they are paid, whether they
are taken in cash or reinvested in additional shares, except that certain
distributions declared in the last three months of the year and paid in January
are taxable as if paid on December 31. All state laws provide a pass-through to
mutual fund shareholders of the state and local income tax exemption afforded
owners of direct U.S. government obligations, although there are conditions to
this treatment in some states. You will be notified annually of the percentage
of a Fund's income that is derived from U.S. government securities.
   If the Fund's distributions exceed its investment company taxable income and
net capital gain in any year, as a result of currency-related losses or
otherwise, all or a portion of those distributions may be treated as a return of
capital to shareholders for tax purposes.
 
   YEAR-END TAX REPORTING. After the end of each calendar year, you will receive
a statement (Form 1099) of the federal income tax status of all dividends and
other distributions paid (or deemed paid) during the year.
 
   SHARES SOLD OR EXCHANGED. Your redemption of shares of the Funds may result
in taxable gain or loss to you, depending upon whether the redemption proceeds
payable to you are more or less than your adjusted cost basis for the redeemed
shares. Similar tax consequences generally will result from an exchange of Fund
shares for shares of another Strong Fund. If you purchase shares of a Fund
within thirty days before or after redeeming shares of the same Fund at a loss,
a portion or all of that loss will not be deductible and will increase the cost
basis of the newly purchased shares. If you redeem shares out of a non-IRA
retirement account, you will be subject to withholding for federal income tax
purposes unless you transfer the distribution directly to an "eligible
retirement plan." In addition, if you redeem all shares in an account at any
time during a month, dividends credited to the account since the beginning of
the month through the day of redemption will be paid with the redemption
proceeds.
 
   BACKUP WITHHOLDING. If you are an individual or certain other noncorporate
shareholder and do not furnish a Fund with a correct taxpayer identification
number, the Fund is required to withhold federal income tax at a rate of 31%
(backup withholding) from all dividends, capital gain distributions, and
redemption proceeds, payable to you. Withholding at that rate from dividends and
capital gain distributions payable to you also is required if you otherwise are
subject to backup withholding. To avoid backup withholding, you must provide a
taxpayer identification number and state that you are not subject to backup
withholding due to the underreporting of your income. This certification is
included as part of your application. Please complete it when you open your
account.
 
   TAX STATUS OF THE FUNDS. Each Fund intends to continue to qualify for
treatment as a regulated investment company under Subchapter M of the
 
                             ----------------------
 
                              PROSPECTUS PAGE I-20
<PAGE>   24
 
Internal Revenue Code and, if so qualified, will not be liable for federal
income tax on earnings and gains distributed to its shareholders in a timely
manner.
   This section is not intended to be a full discussion of present or proposed
federal income tax law and its effects on the Funds and investors therein. See
the SAI for a further discussion. There may be other federal, state, or local
tax considerations applicable to a particular investor. You are therefore urged
to consult your own tax adviser.
 
PERFORMANCE INFORMATION
 
   The Fund may advertise a variety of types of performance information,
including "yield," "average annual total return," "total return," and
"cumulative total return." Each of these figures is based upon historical
results and does not represent the future performance of a Fund.
   Yield is an annualized figure, which means that it is assumed that the Fund
generates the same level of net investment income over a one-year period. The
Fund's yield is a measure of the net investment income per share earned by the
Fund over a specific one-month period and is shown as a percentage of the net
asset value of the Fund's shares at the end of the period.
   Average annual total return and total return figures measure both the net
investment income generated by, and the effect of any realized and unrealized
appreciation or depreciation of, the underlying investments in the Fund assuming
the reinvestment of all dividends and distributions. Total return figures are
not annualized and simply represent the aggregate change of the Fund's
investments over a specified period of time.

HOW TO BUY SHARES
 
   All the Strong Funds are 100% no-load, meaning you may purchase, redeem, or
exchange shares directly at net asset value without paying a sales charge.
Because the Funds' net asset value changes daily, your purchase price will be
the next net asset value determined after Strong receives and accepts your
purchase order. Your money will begin earning dividends the first business day
after your purchase order is accepted in proper form.
   Whether you are opening a new account or adding to an existing one, Strong
provides you with several methods to buy Fund shares.

   Generally, when you make any purchases, sales, or exchanges, the price of
your shares will be the net asset value ("NAV") next determined after Strong
Funds receives your request in proper form. If Strong Funds receives such
request prior to the close of the New York Stock Exchange (the "Exchange") on a
day on which the Exchange is open, your share price will be the NAV determined
that day. The NAV for the Fund is normally determined as of 3:00 p.m. Central
Time ("CT") each day the Exchange is open. The Fund reserves the right to change
the time at which purchases, redemptions, and
 
                             ----------------------
 
                              PROSPECTUS PAGE II-4
<PAGE>   29
 
exchanges are priced if the Exchange closes at a time other than 3:00 p.m. CT or
if an emergency exists. The Fund's NAV is calculated by taking the fair value of
the Fund's total assets, subtracting all its liabilities, and dividing by the
total number of shares outstanding. Expenses are accrued and applied daily when
determining the NAV.
   With respect to the Fund, debt securities are valued by a pricing service
that utilizes electronic data processing techniques to determine values for
normal institutional size trading units of debt securities without regard to the
existence of sale or bid prices when such techniques are believed to more
accurately reflect the fair market value of such securities. Otherwise, sale or
bid prices are used. Any securities or other assets for which market quotations
are not readily available are valued at fair value as determined in good faith
by the Board of Directors. Debt securities having remaining maturities of 60
days or less are valued by the amortized cost method when the Board of Directors
determines that the fair value of such securities is their amortized cost.
 
HOW TO SELL SHARES
 
   You can access the money in your account at any time by selling (redeeming)
some or all of your shares back to the Fund. Once your redemption request is
received in proper form, Strong will normally mail you the proceeds the next
business day and, in any event, no later than seven days thereafter.
   To redeem shares, you may use any of the methods described in the following
chart. However, if you are selling shares in a retirement account, please call
1-800-368-3863 for instructions. Please note that there is a $10.00 fee for
closing an IRA or other retirement account or for transferring assets to another
custodian. For your protection, certain requests may require a signature
guarantee. (See "Special Situations -- Signature Guarantees.")

<PAGE>   31
 
                   WHAT YOU SHOULD KNOW ABOUT SELLING SHARES
 
- - If you have recently purchased shares, please be aware that your redemption
  request may not be honored until the purchase check has cleared your bank,
  which generally occurs within ten calendar days.
- - You will be charged a $10 service fee for a stop-payment and replacement of a
  redemption or dividend check.
- - The right of redemption may be suspended during any period in which (i)
  trading on the Exchange is restricted, as determined by the SEC, or the
  Exchange is closed for other than weekends and holidays; (ii) the SEC has
  permitted such suspension by order; or (iii) an emergency as determined by the
  SEC exists, making disposal of portfolio securities or valuation of net assets
  of the Fund not reasonably practicable.
- - If you are selling shares you hold in certificate form, you must submit the
  certificates with your redemption request. Each registered owner must endorse
  the certificates and all signatures must be guaranteed.
- - Further documentation may be requested from corporations, executors,
  administrators, trustees, guardians, agents, or attorneys-in-fact.
 
                              REDEMPTIONS IN KIND
 
   If the Advisor determines that existing conditions make cash payments
undesirable, redemption payments (including the satisfaction of redemption
checks) may be made in whole or in part in securities or other financial assets,
valued for this purpose as they are valued in computing the NAV for the Fund's
shares. Shareholders receiving securities or other financial assets on
redemption may realize a gain or loss for tax purposes, and will incur any costs
of sale, as well as the associated inconveniences.
 
                WHAT YOU SHOULD KNOW ABOUT TELEPHONE REDEMPTIONS
 
- - The Fund reserves the right to refuse a telephone redemption if they believe
  it advisable to do so.
- - Once you place your telephone redemption request, it cannot be canceled or
  modified.
- - Investors will bear the risk of loss from fraudulent or unauthorized
  instructions received over the telephone provided that the Fund reasonably
  believes that such instructions are genuine. The Fund and its transfer agent
  employ reasonable procedures to confirm that instructions communicated by
  telephone are genuine. The Fund may incur liability if it does not follow
  these procedures.
- - Because of increased telephone volume, you may experience difficulty in
  implementing a telephone redemption during periods of dramatic economic or
  market changes.

                              TRANSACTION SERVICES
 
   EXCHANGE PRIVILEGE. You may exchange shares between identically registered
Strong Funds accounts, either in writing or by telephone. By establishing the
telephone exchange services, you authorize the Fund and its agents to act upon
your instruction by telephone to exchange shares from any account you specify.
For tax purposes, an exchange is considered a sale and a purchase of Fund
shares. Please obtain and read the appropriate prospectus before investing in
any of the Strong Funds. Since an excessive number of exchanges may be
detrimental to the Funds, the Fund reserves the right to discontinue the
exchange privilege of any shareholder who makes more than five exchanges in a
year or three exchanges in a calendar quarter.
 
   CHECK-WRITING PRIVILEGES. You may also redeem shares by check in amounts of
$500 or more. There is no charge for check-writing privileges. Redemption by
check cannot be honored if share certificates are outstanding and would need to
be liquidated to honor the check. In addition, a check may not be honored if the
check results in you redeeming more than the lesser of $250,000 or 1% of the
Fund's assets during any 90-day period and the Advisor determines that existing
conditions make cash payments undesirable. Checks are supplied free of charge,
and additional checks will be sent to you upon request. The Funds do not return
the checks you write, although copies are available upon request.
   You may place stop-payment requests on checks by calling Strong Funds at
1-800-368-3863. A $10 fee will be charged for each stop-payment request. A stop
payment will remain in effect for two weeks following receipt of oral
instructions (six months following written instructions) by Strong Funds.
   If there are insufficient cleared shares in your account to cover the amount
of your redemption by check, the check will be returned, marked "insufficient
funds," and a fee of $10 will be charged to the account.

REGULAR INVESTMENT PLANS
 
   Strong Funds' Automatic Investment Plan, Payroll Direct Deposit Plan, and
Automatic Exchange Plan, all discussed below, are methods of implementing DOLLAR
COST AVERAGING. Dollar cost averaging is an investment strategy that involves
investing a fixed amount of money at regular time intervals. By always investing
the same set amount, you will be purchasing more shares when the price is low
and fewer shares when the price is high. Ultimately, by using this principle in
conjunction with fluctuations in share price, your average cost per share may be
less than your average transaction price. A program of regular investment cannot
ensure a profit or protect against a loss during declining markets. Since such a
program involves continuous investment regardless of fluctuating share values,
you should consider your ability to continue the program through periods of both
low and high share-price levels.
 
   AUTOMATIC INVESTMENT PLAN. The Automatic Investment Plan allows you to make
regular, systematic investments in a Fund from your bank checking or NOW
account. You may choose to make investments on any day of the month in amounts
of $50 or more. You can set up the Automatic Investment Plan with any financial
institution that is a member of the Automated Clearing House. Because each Fund
has the right to close an investor's account for failure to reach the minimum
initial investment, please consider your ability to continue this Plan until you
reach the minimum initial investment. To establish the Plan, complete the
Automatic Investment Plan section on the account application, or call
1-800-368-3863 for an application.
 
   PAYROLL DIRECT DEPOSIT PLAN. Once you meet the Fund's minimum initial
investment requirement, you may purchase additional Fund shares through the
Payroll Direct Deposit Plan. Through this Plan, periodic investments (minimum
$50) are made automatically from your payroll check into your existing Fund
account. By enrolling in the Plan, you authorize your employer or its agents to
deposit a specified amount from your payroll check into the Fund's bank account.
In most cases, your Fund account will be credited the day after the amount is
received by the Fund's bank. In order to participate in the Plan, your employer
must have direct deposit capabilities through the Automated Clearing House
available to its employees. The Plan may be used for other direct deposits, such
as social security checks, military allotments, and annuity payments.
   To establish a Direct Deposit for your account, call 1-800-368-3863 to
request a form. Once the Plan is established, you may alter the amount of the
deposit, alter the frequency of the deposit, or terminate your participation in
the program by notifying your employer.
 
                            -----------------------
 
                              PROSPECTUS PAGE II-10
<PAGE>   35
 
   AUTOMATIC EXCHANGE PLAN. The Automatic Exchange Plan allows you to make
regular, systematic exchanges (minimum $50) from one Strong Funds account into
another Strong Funds account. By setting up the Plan, you authorize the Fund and
its agents to redeem a set dollar amount or number of shares from the first
account and purchase shares of a second Strong Fund. In addition, you authorize
a Fund and its agents to accept telephone instructions to change the dollar
amount and frequency of the exchange. An exchange transaction is a sale and
purchase of shares for federal income tax purposes and may result in a capital
gain or loss. To establish the Plan, request a form by calling 1-800-368-3863.
   To participate in the Automatic Exchange Plan, you must have an initial
account balance of $2,500 in the first account and at least the minimum initial
investment in the second account. Exchanges may be made on any day or days of
your choice. If the amount remaining in the first account is less than the
exchange amount you requested, then the remaining amount will be exchanged. At
such time as the first account has a zero balance, your participation in the
Plan will be terminated. You may also terminate the Plan at any time by calling
or writing to the Fund. Once participation in the Plan has been terminated for
any reason, to reinstate the Plan you must do so in writing; simply investing
additional funds will not reinstate the Plan.
 
   SYSTEMATIC WITHDRAWAL PLAN. You can set up automatic withdrawals from your
account at regular intervals. To begin distributions, you must have an initial
balance of $5,000 in your account and withdraw at least $50 per payment. To
establish the Systematic Withdrawal Plan, request a form by calling
1-800-368-3863. Depending upon the size of the account and the withdrawals
requested (and fluctuations in net asset value of the shares redeemed),
redemptions for the purpose of satisfying such withdrawals may reduce or even
exhaust the account. If the amount remaining in the account is not sufficient to
meet a Plan payment, the remaining amount will be redeemed and the Plan will be
terminated.
 
RETIREMENT PLAN SERVICES
 
   We offer a wide variety of retirement plans for individuals and institutions,
including large and small businesses. For information on IRAs or SEP-IRAs for a
one-person business, call 1-800-368-3863. If you are interested in opening a
401(k) or other company-sponsored retirement plan (Simples, SEP plans, Keoghs,
403(b)(7) plans, pension and profit sharing plans), call 1-800-368-0805 and a
Strong Retirement Plan Specialist will help you determine which retirement plan
would be best for your company. Complete instructions about how to establish and
maintain your plan and how to open accounts for you and your employees will be
included in the retirement plan kit you receive in the mail.

SPECIAL SITUATIONS
 
   POWER OF ATTORNEY. If you are investing as attorney-in-fact for another
person, please complete the account application in the name of such person and
sign the back of the application in the following form: "[applicant's name] by
[your name], attorney-in-fact." To avoid having to file an affidavit prior to
each transaction, please complete the Power of Attorney form available from
Strong Funds at 1-800-368-3863. However, if you would like to use your own power
of attorney form, please call the same number for instructions.
 
   CORPORATIONS AND TRUSTS. If you are investing for a corporation, please
include with your account application a certified copy of your corporate
resolution indicating which officers are authorized to act on behalf of the
corporation. As an alternative, you may complete a Certification of Authorized
Individuals, which can be obtained from the Funds. Until a valid corporate
resolution or Certification of Authorized Individuals is received by the Fund,
services such as telephone redemption, wire redemption, and check writing will
not be established.
   If you are investing as a trustee, please include the date of the trust. All
trustees must sign the application. If they do not, services such as telephone
redemption, wire redemption, and check writing will not be established. All
trustees must sign redemption requests unless proper documentation to the
contrary is provided to the Fund. Failure to provide these documents or
signatures as required when you invest may result in delays in processing
redemption requests.
 
   FINANCIAL INTERMEDIARIES. Broker-dealers, financial institutions, and other
financial intermediaries that have entered into agreements with the Distributor
may enter purchase or redemption orders on behalf of their customers. If you
purchase or redeem shares of the Fund through a financial intermediary, certain
features of the Fund relating to such transactions may not be available or may
be modified in accordance with the terms of the intermediaries' agreement with
the Distributor. In addition, certain operational policies of the Fund,
including those related to settlement and dividend accrual, may vary from those
applicable to direct shareholders of the Fund and may vary among intermediaries.
We urge you to consult your financial intermediary for more information
regarding these matters. In addition, the Fund may pay, directly or indirectly
through arrangements with the Advisor, amounts to financial intermediaries that
provide transfer agent and/or other administrative services relating to the Fund
to their customers provided, however, that the Fund will not pay more for these
services through intermediary relationships than it would if the intermediaries'
customers were direct shareholders in the Fund. Certain financial intermediaries
may charge a commission or other transaction fee for their services. You will
not be charged for such fees if you purchase or
 
                            -----------------------

redeem your Fund shares directly from a Fund without the intervention of a
financial intermediary.
 
   SIGNATURE GUARANTEES. A signature guarantee is designed to protect you and
the Funds against fraudulent transactions by unauthorized persons. In the
following instances, the Funds will require a signature guarantee for all
authorized owners of an account:
 
- - when you add the telephone redemption or check-writing options to your
  existing account;
- - if you transfer the ownership of your account to another individual or
  organization;
- - when you submit a written redemption request for more than $25,000;
- - when you request to redeem or redeposit shares that have been issued in
  certificate form;
- - if you open an account and later decide that you want certificates;
- - when you request that redemption proceeds be sent to a different name or
  address than is registered on your account;
- - if you add/change your name or add/remove an owner on your account; and
- - if you add/change the beneficiary on your transfer-on-death account.
 
   A signature guarantee may be obtained from any eligible guarantor
institution, as defined by the SEC. These institutions include banks, savings
associations, credit unions, brokerage firms, and others. PLEASE NOTE THAT A
NOTARY PUBLIC STAMP OR SEAL IS NOT ACCEPTABLE.

                            INVESTMENT RESTRICTIONS

     The investment objective of the Fund is to seek total return by investing
for a high level of current income with a moderate degree of share-price
fluctuation.  The Fund's investment objectives and policies are described in
detail in the Prospectus under the caption "Investment Objective and Policies."
The following are the Fund's fundamental investment limitations which cannot
be changed without shareholder approval.

The Fund:

1.   May not with respect to 75% of its total assets, purchase the securities
     of any issuer (except securities issued or guaranteed by the U.S.
     government or its agencies or instrumentalities) if, as a result, (i) more
     than 5% of the Fund's total assets would be invested in the securities of
     that issuer, or (ii) the Fund would hold more than 10% of the outstanding
     voting securities of that issuer.

2.   May (i) borrow money from banks and (ii) make other investments or engage
     in other transactions permissible under the Investment Company Act of 1940
     (the "1940 Act") which may involve a borrowing, provided that the
     combination of (i) and (ii) shall not exceed 33 1/3% of the value of the
     Fund's total assets (including the amount borrowed), less the Fund's
     liabilities (other than borrowings), except that the Fund may borrow up to
     an additional 5% of its total assets (not including the amount borrowed)
     from a bank for temporary or emergency purposes (but not for leverage or
     the purchase of investments).  The Fund may also borrow money from the
     other Strong Funds or other persons to the extent permitted by applicable
     law.

3.   May not issue senior securities, except as permitted under the 1940 Act.

4.   May not act as an underwriter of another issuer's securities, except to
     the extent that the Fund may be deemed to be an underwriter within the
     meaning of the Securities Act of 1933 in connection with the purchase and
     sale of portfolio securities.

5.   May not purchase or sell physical commodities unless acquired as a result
     of ownership of securities or other instruments (but this shall not
     prevent the Fund from purchasing or selling options, futures contracts, or
     other derivative instruments, or from investing in securities or other
     instruments backed by physical commodities).

6.   May not make loans if, as a result, more than 33 1/3% of the Fund's total
     assets would be lent to other persons, except through (i) purchases of
     debt securities or other debt instruments, or (ii) engaging in repurchase
     agreements.

7.   May not purchase the securities of any issuer if, as a result, more than
     25% of the Fund's total assets would be invested in the securities of
     issuers, the principal business activities of which are in the same
     industry.  With respect to the Money Market Funds only, this limitation
     shall not limit the Funds' purchases of obligations issued by domestic
     banks.

8.   May not purchase or sell real estate unless acquired as a result of
     ownership of securities or other instruments (but this shall not prohibit
     the Fund from purchasing or selling securities or other instruments backed
     by real estate or of issuers engaged in real estate activities).

9.   May, notwithstanding any other fundamental investment policy or
     restriction, invest all of its assets in the securities of a single
     open-end management investment company with substantially the same
     fundamental investment objective, policies, and restrictions as the Fund.


                                    - 3 -
<PAGE>   43


     The following are the Fund's non-fundamental operating policies which may
be changed by the Board of Directors of the Fund without shareholder approval.

The Fund may not:

1.   Sell securities short, unless the Fund owns or has the right to obtain
     securities equivalent in kind and amount to the securities sold short, or
     unless it covers such short sale as required by the current rules and
     positions of the Securities and Exchange Commission or its staff, and
     provided that transactions in options, futures contracts, options on
     futures contracts, or other derivative instruments are not deemed to
     constitute selling securities short.

2.   Purchase securities on margin, except that the Fund may obtain such
     short-term credits as are necessary for the clearance of transactions; and
     provided that margin deposits in connection with futures contracts,
     options on futures contracts, or other derivative instruments shall not
     constitute purchasing securities on margin.

3.   Invest in illiquid securities if, as a result of such investment, more
     than 15% of its net assets would be invested in illiquid securities, or
     such other amounts as may be permitted under the 1940 Act.

4.   Purchase securities of other investment companies except in compliance
     with the 1940 Act and applicable state law.

5.   Invest all of its assets in the securities of a single open-end
     investment management company with substantially the same fundamental
     investment objective, restrictions and policies as the Fund.

6.   Engage in futures or options on futures transactions which are
     impermissible pursuant to Rule 4.5 under the Commodity Exchange Act and,
     in accordance with Rule 4.5, will use futures or options on futures
     transactions solely for bona fide hedging transactions (within the 
     meaning of the Commodity Exchange Act), provided, however,  that the Fund 
     may, in addition to bona fide hedging transactions, use futures and 
     options on futures transactions if the aggregate initial margin and 
     premiums required to establish such positions, less the amount by which 
     any such options positions are in the money (within the meaning of the 
     Commodity Exchange Act), do not exceed 5% of the Fund's net assets.

7.   Borrow money except (i) from banks or (ii) through reverse repurchase
     agreements or mortgage dollar rolls, and will not purchase securities when
     bank borrowings exceed 5% of its total assets.

8.   Make any loans other than loans of portfolio securities, except through
     (i) purchases of debt securities or other debt instruments, or (ii)
     engaging in repurchase agreements.

     Except for the fundamental investment limitations listed above and the
Fund's investment objective, the other investment policies described in the
Prospectus and this Statement of Additional Information are not fundamental and
may be changed with approval of the Fund's Board of Directors.  Unless noted
otherwise, if a percentage restriction is adhered to at the time of investment,
a later increase or decrease in percentage resulting from a change in the
Fund's assets (i.e., due to cash inflows or redemptions) or in market value of
the investment or the Fund's assets will not constitute a violation of that
restriction.

                       INVESTMENT POLICIES AND TECHNIQUES

     The following information supplements the discussion of the Fund's
investment objectives, policies and techniques that are described in detail in
the Prospectus under the captions "Investment Objective and Policies" and
"Implementation of Policies and Risks."

BORROWING

     The Fund may borrow money from banks and make other investments or engage
in other transactions permissible under the 1940 Act which may be considered a
borrowing (such as mortgage dollar rolls and reverse repurchase agreements) as
discussed under "Investment Restrictions."  However, the Fund may not purchase
securities when bank borrowings exceed 5% of the Fund's total assets.
Presently, the Fund only intends to borrow from banks for temporary or
emergency purposes.

     The Fund has established a line-of-credit (LOC) with certain banks by
which it may borrow funds for temporary or emergency purposes.  A borrowing is
presumed to be for temporary or emergency purposes if it is repaid by the Fund
within sixty days and is not extended or renewed.  The Fund intends to use the
LOC to meet large or unexpected redemptions that would otherwise force the Fund
to liquidate securities under circumstances which are unfavorable to the Fund's
remaining shareholders.  The Fund pays a commitment fee to the banks for the
LOC.

CONVERTIBLE SECURITIES

     The Fund may invest in convertible securities, which are bonds,
debentures, notes, preferred stocks, or other securities that may be converted
into or exchanged for a specified amount of common stock of the same or a
different issuer within a particular period of time at a specified price or
formula.  A convertible security entitles the holder to receive interest
normally paid or accrued on debt or the dividend paid on preferred stock until
the convertible security matures or is redeemed, converted, or exchanged.
Convertible securities have unique investment characteristics in that they
generally (i) have higher yields than common stocks, but lower yields than
comparable non-convertible securities, (ii) are less subject to fluctuation in
value than the underlying stock since they have fixed income characteristics,
and (iii) provide the potential for capital appreciation if the market price of
the underlying common stock increases.  Most convertible securities currently
are issued by U.S.  companies, although a substantial Eurodollar convertible
securities market has developed, and the markets for convertible securities
denominated in local currencies are increasing.

     The value of a convertible security is a function of its "investment
value" (determined by its yield in comparison with the yields of other
securities of comparable maturity and quality that do not have a conversion
privilege) and its "conversion value" (the security's worth, at market value,
if converted into the underlying common stock).  The investment value of a
convertible security is influenced by changes in interest rates, with
investment value declining as interest rates increase and increasing as
interest rates decline.  The credit standing of the issuer and other factors
also may have an effect on the convertible security's investment value.  The
conversion value of a convertible security is determined by the market price of
the underlying common stock.  If the conversion value is low relative to the
investment value, the price of the convertible security is governed principally
by its investment value.  Generally, the conversion value decreases as the
convertible security approaches maturity.  To the extent the market price of
the underlying common stock approaches or exceeds the conversion price, the
price of the convertible security will be increasingly influenced by its
conversion value.  A convertible security generally will sell at a premium over
its conversion value by the extent to which investors place value on the right
to acquire the underlying common stock while holding a fixed income security.

     A convertible security may be subject to redemption at the option of the
issuer at a price established in the convertible security's governing
instrument.  If a convertible security held by the Fund is called for
redemption, the Fund will be required to permit the issuer to redeem the
security, convert it into the underlying common stock, or sell it to a third
party.

DEPOSITARY RECEIPTS

     The Fund may invest in foreign securities by purchasing depositary
receipts, including American Depositary Receipts ("ADRs") and European
Depositary Receipts ("EDRs"), or other securities convertible into securities
of foreign issuers.  These securities may not necessarily be denominated in the
same currency as the securities into which they may be converted.  Generally,
ADRs, in registered form, are denominated in U.S. dollars and are designed for
use in the U.S.  securities markets, while EDRs, in bearer form, may be
denominated in other currencies and are designed for use in the European
securities markets.  ADRs are receipts typically issued by a U.S. bank or trust
company evidencing ownership of the underlying securities.  EDRs are European
receipts evidencing a similar arrangement.  For purposes of the Fund's
investment policies, ADRs and EDRs are deemed to have the same classification
as the underlying securities they represent, except that ADRs and

                                     - 5 -

<PAGE>   45

EDRs shall be treated as indirect foreign investments.  Thus, an ADR or EDR
representing ownership of common stock will be treated as common stock.  ADR
and EDR depositary receipts do not eliminate all of the risks associated with
directly investing in the securities of foreign issuers.

     ADR facilities may be established as either "unsponsored" or "sponsored."
While ADRs issued under these two types of facilities are in some respects
similar, there are distinctions between them relating to the rights and
obligations of ADR holders and the practices of market participants.

     A depositary may establish an unsponsored facility without participation
by (or even necessarily the acquiescence of) the issuer of the deposited
securities, although typically the depositary requests a letter of
non-objection from such issuer prior to the establishment of the facility.
Holders of unsponsored ADRs generally bear all the costs of such facilities.
The depositary usually charges fees upon the deposit and withdrawal of the
deposited securities, the conversion of dividends into U.S.  dollars, the
disposition of non-cash distributions, and the performance of other services.
The depositary of an unsponsored facility frequently is under no obligation to
pass through voting rights to ADR holders in respect of the deposited
securities.  In addition, an unsponsored facility is generally not obligated to
distribute communications received from the issuer of the deposited securities
or to disclose material information about such issuer in the U.S.  and thus
there may not be a correlation between such information and the market value of
the depositary receipts.

     Sponsored ADR facilities are created in generally the same manner as
unsponsored facilities, except that the issuer of the deposited securities
enters into a deposit agreement with the depositary.  The deposit agreement
sets out the rights and responsibilities of the issuer, the depositary, and the
ADR holders.  With sponsored facilities, the issuer of the deposited securities
generally will bear some of the costs relating to the facility (such as
dividend payment fees of the depositary), although ADR holders continue to bear
certain other costs (such as deposit and withdrawal fees).  Under the terms of
most sponsored arrangements, depositories agree to distribute notices of
shareholder meetings and voting instructions, and to provide shareholder
communications and other information to the ADR holders at the request of the
issuer of the deposited securities.

DERIVATIVE INSTRUMENTS

     IN GENERAL.  The Fund may use derivative instruments for any lawful
purpose consistent with the Fund's investment objective such as hedging or
managing risk.  Derivative instruments are commonly defined to include
securities or contracts whose values depend on (or "derive" from) the value of
one or more other assets, such as securities, currencies, or commodities.
These "other assets" are commonly referred to as "underlying assets."

     A derivative instrument generally consists of, is based upon, or exhibits
characteristics similar to options or forward contracts. Options and forward
contracts are considered to be the basic "building blocks" of derivatives. For
example, forward-based derivatives include forward contracts, swap contracts,
as well as exchange-traded futures. Option-based derivatives include privately
negotiated, over-the-counter (OTC) options (including caps, floors, collars,
and options on forward and swap contracts) and exchange-traded options on
futures. Diverse types of derivatives may be created by combining options or
forward contracts in different ways, and by applying these structures to a wide
range of underlying assets.

     An option is a contract in which the "holder" (the buyer) pays a certain
amount (the "premium") to the "writer" (the seller) to obtain the right, but
not the obligation, to buy from the writer (in a "call") or sell to the writer
(in a "put") a specific asset at an agreed upon price at or before a certain
time.  The holder pays the premium at inception and has no further financial
obligation.  The holder of an option-based derivative generally will benefit
from favorable movements in the price of the underlying asset but is not
exposed to corresponding losses due to adverse movements in the value of the
underlying asset.  The writer of an option-based derivative generally will
receive fees or premiums but generally is exposed to losses due to changes in
the value of the underlying asset.

     A forward is a sales contract between a buyer (holding the "long"
position) and a seller (holding the "short" position) for an asset with
delivery deferred until a future date.  The buyer agrees to pay a fixed price
at the agreed future date and the seller agrees to deliver the asset.  The
seller hopes that the market price on the delivery date is less than the agreed
upon price, while the buyer hopes for the contrary. The change in value of a
forward-based derivative generally is roughly proportional to the change in
value of the underlying asset.

     HEDGING.  The Fund may use derivative instruments to protect against
possible adverse changes in the market value of securities held in, or are
anticipated to be held in, the Fund's portfolio.  Derivatives may also be used
by the Fund to "lock-in" the Fund's realized but unrecognized gains in the
value of its portfolio securities.  Hedging strategies, if successful, can
reduce the risk of loss by wholly or partially offsetting the negative effect
of unfavorable price movements in the investments being hedged.  However,
hedging strategies can also reduce the opportunity for gain by offsetting the
positive effect of favorable price movements in the hedged investments.

     MANAGING RISK.  The Fund may also use derivative instruments to manage the
risks of the Fund's portfolio.  Risk management strategies include, but are not
limited to, facilitating the sale of portfolio securities, managing the
effective maturity or duration of debt obligations in the Fund's portfolio,
establishing a position in the derivatives markets as a substitute for buying
or selling certain securities, or creating or altering exposure to certain
asset classes, such as equity, debt, and foreign securities.  The use of
derivative instruments may provide a less expensive, more expedient or more
specifically focused way for the Fund to invest than "traditional" securities
(i.e., stocks or bonds) would.

     EXCHANGE OR OTC DERIVATIVES.  Derivative instruments may be
exchange-traded or traded in OTC transactions between private parties.
Exchange-traded derivatives are standardized options and futures contracts
traded in an auction on the floor of a regulated exchange.  Exchange contracts
are generally very liquid.  The exchange clearinghouse is the counterparty of
every contract.  Thus, each holder of an exchange contract bears the credit
risk of the clearinghouse (and has the benefit of its financial strength)
rather than that of a particular counterparty.  Over-the-counter transactions
are subject to additional risks, such as the credit risk of the counterparty to
the instrument and are less liquid than exchange-traded derivatives since they
often can only be closed out with the other party to the transaction.

     RISKS AND SPECIAL CONSIDERATIONS.  The use of derivative instruments
involves risks and special considerations as described below.  Risks pertaining
to particular derivative instruments are described in the sections that follow.

     (1) MARKET RISK.  The primary risk of derivatives is the same as the risk
of the underlying assets, namely that the value of the underlying asset may go
up or down.  Adverse movements in the value of an underlying asset can expose
the Fund to losses.  Derivative instruments may include elements of leverage
and, accordingly, the fluctuation of the value of the derivative instrument in
relation to the underlying asset may be magnified.  The successful use of
derivative instruments depends upon a variety of factors, particularly Strong
Capital Management, Inc.'s (the "Advisor'") ability to predict movements of the
securities, currencies, and commodity markets, which requires different skills
than predicting changes in the prices of individual securities.  There can be
no assurance that any particular strategy adopted will succeed.  The Advisor's
decision to engage in a derivative instrument will reflect the Advisor's
judgment that the derivative transaction will provide value to the Fund and its
shareholders and is consistent with the Fund's objectives, investment
limitations, and operating policies.  In making such a judgment, the Advisor
will analyze the benefits and risks of the derivative transaction and weigh
them in the context of the Fund's entire portfolio and investment objective.

     (2) CREDIT RISK.  The Fund will be subject to the risk that a loss may be
sustained by the Fund as a result of the failure of a counterparty to comply
with the terms of a derivative instrument.  The counterparty risk for
exchange-traded derivative instruments is generally less than for
privately-negotiated or OTC derivative instruments, since generally a clearing
agency, which is the issuer or counterparty to each exchange-traded instrument,
provides a guarantee of performance.  For privately-negotiated instruments,
there is no similar clearing agency guarantee.  In all transactions, the Fund
will bear the risk that the counterparty will default, and this could result in
a loss of the expected benefit of the derivative transaction and possibly other
losses to the Fund.  The Fund will enter into transactions in derivative
instruments only with counterparties that the Advisor reasonably believes are
capable of performing under the contract.

     (3) CORRELATION RISK.  When a derivative transaction is used to completely
hedge another position, changes in the market value of the combined position
(the derivative instrument plus the position being hedged) result from an
imperfect correlation between the price movements of the two instruments.  With
a perfect hedge, the value of the combined position remains unchanged for any
change in the price of the underlying asset.  With an imperfect hedge, the
values of the derivative instrument and its hedge are not perfectly correlated.
Correlation risk is the risk that there might be imperfect correlation, or
even no correlation, between price movements of an instrument and price
movements of investments being hedged.  For example, if the value of a
derivative instruments used in a short hedge (such as writing a call option,
buying a put option, or selling a futures contract) increased by less than the
decline in value of the hedged investments, the hedge would not be

                                     - 7 -

<PAGE>   47

perfectly correlated.  Such a lack of correlation might occur due to factors
unrelated to the value of the investments being hedged, such as speculative or
other pressures on the markets in which these instruments are traded.  The
effectiveness of hedges using instruments on indices will depend, in part, on
the degree of correlation between price movements in the index and price
movements in the investments being hedged.

     (4) LIQUIDITY RISK.  Derivatives are also subject to liquidity risk.
Liquidity risk is the risk that a derivative instrument cannot be sold, closed
out, or replaced quickly at or very close to its fundamental value.  Generally,
exchange contracts are very liquid because the exchange clearinghouse is the
counterparty of every contract.  OTC transactions are less liquid than
exchange-traded derivatives since they often can only be closed out with the
other party to the transaction.  The Fund might be required by applicable
regulatory requirement to maintain assets as "cover," maintain segregated
accounts, and/or make margin payments when it takes positions in derivative
instruments involving obligations to third parties (i.e., instruments other
than purchased options).  If the Fund was  unable to close out its positions in
such instruments, it might be required to continue to maintain such assets or
accounts or make such payments until the position expired, matured, or was
closed out.  The requirements might impair the Fund's ability to sell a
portfolio security or make an investment at a time when it would otherwise be
favorable to do so, or require that the Fund sell a portfolio security at a
disadvantageous time.  The Fund's ability to sell or close out a position in an
instrument prior to expiration or maturity depends on the existence of a liquid
secondary market or, in the absence of such a market, the ability and
willingness of the counterparty to enter into a transaction closing out the
position.  Therefore, there is no assurance that any derivatives  position can
be sold or closed out at a time and price that is favorable to the Fund.

     (5) LEGAL RISK.  Legal risk is the risk of loss caused by the legal
unenforcibility of a party's obligations under the derivative.  While a party
seeking price certainty agrees to surrender the potential upside in exchange
for downside protection, the party taking the risk is looking for a positive
payoff.  Despite this voluntary assumption of risk, a counterparty that has
lost money in a derivative transaction may try to avoid payment by exploiting
various legal uncertainties about certain derivative products.

     (6) SYSTEMIC OR "INTERCONNECTION" RISK.  Interconnection risk is the risk
that a disruption in the financial markets will cause difficulties for all
market participants.  In other words, a disruption in one market will spill
over into other markets, perhaps creating a chain reaction.  Much of the OTC
derivatives market takes place among the OTC dealers themselves, thus creating
a large interconnected web of financial obligations.  This interconnectedness
raises the possibility that a default by one large dealer could create losses
at other dealers and destabilize the entire market for OTC derivative
instruments.

     GENERAL LIMITATIONS.  The use of derivative instruments is subject to
applicable regulations of the Securities and Exchange Commission (the "SEC"),
the several options and futures exchanges upon which they may be traded, the
Commodity Futures Trading Commission ("CFTC"), and various state regulatory
authorities.  In addition, the Fund's ability to use derivative instruments may
be limited by certain tax considerations.  For a discussion of the federal
income tax treatment of the Fund's derivative instruments, see "Taxes -
Derivative Instruments."

     The Fund has filed a notice of eligibility for exclusion from the
definition of the term "commodity pool operator" with the CFTC and the National
Futures Association, which regulate trading in the futures markets.  In
accordance with Rule 4.5 of the regulations under the Commodity Exchange Act
(the "CEA"), the notice of eligibility for the Fund includes representations
that the Fund will use futures contracts and related options solely for bona
fide hedging purposes within the meaning of CFTC regulations, provided that the
Fund may hold other positions in futures contracts and related options that do
not qualify as a bona fide hedging position if the aggregate initial margin
deposits and premiums required to establish these positions, less the amount by
which any such futures contracts and related options positions are "in the
money," do not exceed 5% of the Fund's net assets.  Adherence to these
guidelines does not limit the Fund's risk to 5% of the Fund's assets.

     The SEC has identified certain trading practices involving derivative
instruments that involve the potential for leveraging the Fund's assets in a
manner that raises issues under the 1940 Act.  In order to limit the potential
for the leveraging of the Fund's assets, as defined under the 1940 Act, the SEC
has stated that the Fund may use coverage or the segregation of the Fund's
assets.  To the extent required by SEC guidelines, the Fund will not enter into
any such transactions unless it owns either: (i) an offsetting ("covered")
position in securities, options, futures, or derivative instruments; or (ii)
cash or liquid securities positions with a value sufficient at all times to
cover its potential obligations to the extent that the position is not

                                     - 8 -

<PAGE>   48

"covered".  The Fund will also set aside cash and/or appropriate liquid assets
in a segregated custodial account if required to do so by the SEC and CFTC
regulations.  Assets used as cover or held in a segregated account cannot be
sold while the derivative position is open, unless they are replaced with
similar assets.  As a result, the commitment of a large portion of the Fund's
assets to segregated accounts could impede portfolio management or the Fund's
ability to meet redemption requests or other current obligations.

     In some cases the Fund may be required to maintain or limit exposure to a
specified percentage of its assets to a particular asset class.  In such cases,
when the Fund uses a derivative instrument to increase or decrease exposure to
an asset class and is required by applicable SEC guidelines to set aside liquid
assets in a segregated account to secure its obligations under the derivative
instruments, the Advisor may, where reasonable in light of the circumstances,
measure compliance with the applicable percentage by reference to the nature of
the economic exposure created through the use of the derivative instrument and
not by reference to the nature of the exposure arising from the liquid assets
set aside in the segregated account (unless another interpretation is specified
by applicable regulatory requirements).

     OPTIONS.  The Fund may use options for any lawful purpose consistent with
the Fund's investment objective such as hedging or managing risk.  An option is
a contract in which the "holder" (the buyer) pays a certain amount (the
"premium") to the "writer" (the seller) to obtain the right, but not the
obligation, to buy from the writer (in a "call") or sell to the writer (in a
"put") a specific asset at an agreed upon price (the "strike price" or
"exercise price") at or before a certain time (the "expiration date").  The
holder pays the premium at inception and has no further financial obligation.
The holder of an option will benefit from favorable movements in the price of
the underlying asset but is not exposed to corresponding losses due to adverse
movements in the value of the underlying asset.  The writer of an option will
receive fees or premiums but is exposed to losses due to changes in the value
of the underlying asset.  The Fund may buy or write (sell) put and call options
on assets, such as securities, currencies, commodities, and indices of debt and
equity securities ("underlying assets") and enter into closing transactions
with respect to such options to terminate an existing position.  Options used
by the Funds may include European, American, and Bermuda style options.  If an
option is exercisable only at maturity, it is a "European" option; if it is
also exercisable prior to maturity, it is an "American" option.  If it is
exercisable only at certain times, it is a "Bermuda" option.

     The Fund may purchase (buy) and write (sell) put and call options
underlying assets and enter into closing transactions with respect to such
options to terminate an existing position.  The purchase of call options serves
as a long hedge, and the purchase of put options serves as a short hedge.
Writing put or call options can enable the Fund to enhance income by reason of
the premiums paid by the purchaser of such options.  Writing call options
serves as a limited short hedge because declines in the value of the hedged
investment would be offset to the extent of the premium received for writing
the option.  However, if the security appreciates to a price higher than the
exercise price of the call option, it can be expected that the option will be
exercised and the Fund will be obligated to sell the security at less than its
market value or will be obligated to purchase the security at a price greater
than that at which the security must be sold under the option.  All or a
portion of any assets used as cover for OTC options written by the Fund would
be considered illiquid to the extent described under "Investment Policies and
Techniques -- Illiquid Securities."  Writing put options serves as a limited
long hedge because increases in the value of the hedged investment would be
offset to the extent of the premium received for writing the option.  However,
if the security depreciates to a price lower than the exercise price of the put
option, it can be expected that the put option will be exercised and the Fund
will be obligated to purchase the security at more than its market value.

     The value of an option position will reflect, among other things, the
historical price volatility of the underlying investment, the current market
value of the underlying investment, the time remaining until expiration, the
relationship of the exercise price to the market price of the underlying
investment, and general market conditions.

     The Fund may effectively terminate its right or obligation under an option
by entering into a closing transaction.  For example, the Fund may terminate
its obligation under a call or put option that it had written by purchasing an
identical call or put option; this is known as a closing purchase transaction.
Conversely, the Fund may terminate a position in a put or call option it had
purchased by writing an identical put or call option; this is known as a
closing sale transaction.  Closing transactions permit the Fund to realize the
profit or limit the loss on an option position prior to its exercise or
expiration.

     The Fund may purchase or write both exchange-traded and OTC options.
Exchange-traded options are issued by a clearing organization affiliated with
the exchange on which the option is listed that, in effect, guarantees
completion of every exchange-traded option transaction.  In contrast, OTC
options are contracts between the Fund and the other party to the

                                     - 9 -

<PAGE>   49

transaction ("counter party") (usually a securities dealer or a bank) with no
clearing organization guarantee.  Thus, when the Fund purchases or writes an
OTC option, it relies on the counter party to make or take delivery of the
underlying investment upon exercise of the option.  Failure by the counter
party to do so would result in the loss of any premium paid by the Fund as well
as the loss of any expected benefit of the transaction.

     The Fund's ability to establish and close out positions in exchange-listed
options depends on the existence of a liquid market.  The Fund intends to
purchase or write only those exchange-traded options for which there appears to
be a liquid secondary market.  However, there can be no assurance that such a
market will exist at any particular time.  Closing transactions can be made for
OTC options only by negotiating directly with the counter party, or by a
transaction in the secondary market if any such market exists.  Although the
Fund will enter into OTC options only with counter parties that are expected to
be capable of entering into closing transactions with the Fund, there is no
assurance that the Fund will in fact be able to close out an OTC option at a
favorable price prior to expiration.  In the event of insolvency of the counter
party, the Fund might be unable to close out an OTC option position at any time
prior to its expiration.  If the Fund was unable to effect a closing
transaction for an option it had purchased, it would have to exercise the
option to realize any profit.

     The Fund may engage in options transactions on indices in much the same
manner as the options on securities discussed above, except the index options
may serve as a hedge against overall fluctuations in the securities market in
general.

     The writing and purchasing of options is a highly specialized activity
that involves investment techniques and risks different from those associated
with ordinary portfolio securities transactions.  Imperfect correlation between
the options and securities markets may detract from the effectiveness of
attempted hedging.

     SPREAD TRANSACTIONS.  The Fund may use spread transactions for any lawful
purpose consistent with the Fund's investment objective such as hedging or
managing risk.  The Fund may purchase covered spread options from securities
dealers.  Such covered spread options are not presently exchange-listed or
exchange-traded.  The purchase of a spread option gives the Fund the right to
put, or sell, a security that it owns at a fixed dollar spread or fixed yield
spread in relationship to another security that the Fund does not own, but
which is used as a benchmark.  The risk to the Fund in purchasing covered
spread options is the cost of the premium paid for the spread option and any
transaction costs.  In addition, there is no assurance that closing
transactions will be available.  The purchase of spread options will be used to
protect the Fund against adverse changes in prevailing credit quality spreads,
i.e., the yield spread between high quality and lower quality securities.  Such
protection is only provided during the life of the spread option.

     FUTURES CONTRACTS.  The Fund may use futures contracts for any lawful
purpose consistent with the Fund's investment objective such as hedging or
managing risk.  The Fund may enter into futures contracts, including interest
rate, index, and currency futures.  The Fund may also purchase put and call
options, and write covered put and call options, on futures in which it is
allowed to invest.  The purchase of futures or call options thereon can serve
as a long hedge, and the sale of futures or the purchase of put options thereon
can serve as a short hedge.  Writing covered call options on futures contracts
can serve as a limited short hedge, and writing covered put options on futures
contracts can serve as a limited long hedge, using a strategy similar to that
used for writing covered options in securities.  The Fund's hedging may include
purchases of futures as an offset against the effect of expected increases in
currency exchange rates and securities prices and sales of futures as an offset
against the effect of expected declines in currency exchange rates and
securities prices.  The Fund may also write put options on futures contracts
while at the same time purchasing call options on the same futures contracts in
order to create synthetically a long futures contract position.  Such options
would have the same strike prices and expiration dates.  The Fund will engage
in this strategy only when the Advisor believes it is more advantageous to the
Fund than is purchasing the futures contract.

     To the extent required by regulatory authorities, the Fund only enters
into futures contracts that are traded on national futures exchanges and are
standardized as to maturity date and underlying financial instrument.  Futures
exchanges and trading are regulated under the CEA by the CFTC.  Although
techniques other than sales and purchases of futures contracts could be used to
reduce the Fund's exposure to market, currency, or interest rate fluctuations,
the Fund may be able to hedge its exposure more effectively and perhaps at a
lower cost through using futures contracts.

     An interest rate futures contract provides for the future sale by one
party and purchase by another party of a specified amount of a specific
financial instrument (e.g., debt security) or currency for a specified price at
a designated date, time, and place.  An index futures contract is an agreement
pursuant to which the parties agree to take or make delivery of an amount of

                                     - 10 -

<PAGE>   50



cash equal to the difference between the value of the index at the close of the
last trading day of the contract and the price at which the index futures
contract was originally written.  Transaction costs are incurred when a futures
contract is bought or sold and margin deposits must be maintained.  A futures
contract may be satisfied by delivery or purchase, as the case may be, of the
instrument, the currency or by payment of the change in the cash value of the
index.  More commonly, futures contracts are closed out prior to delivery by
entering into an offsetting transaction in a matching futures contract.
Although the value of an index might be a function of the value of certain
specified securities, no physical delivery of those securities is made.  If the
offsetting purchase price is less than the original sale price, the Fund
realizes a gain; if it is more, the Fund realizes a loss.  Conversely, if the
offsetting sale price is more than the original purchase price, the Fund
realizes a gain; if it is less, the Fund realizes a loss.  The transaction
costs must also be included in these calculations.  There can be no assurance,
however, that the Fund will be able to enter into an offsetting transaction
with respect to a particular futures contract at a particular time.  If the
Fund is not able to enter into an offsetting transaction, the Fund will
continue to be required to maintain the margin deposits on the futures
contract.

     No price is paid by the Fund upon entering into a futures contract.
Instead, at the inception of a futures contract, the Fund is required to
deposit in a segregated account with its custodian, in the name of the futures
broker through whom the transaction was effected, "initial margin" consisting
of cash and/or other appropriate liquid assets in an amount generally equal to
10% or less of the contract value.  Margin must also be deposited when writing
a call or put option on a futures contract, in accordance with applicable
exchange rules.  Unlike margin in securities transactions, initial margin on
futures contracts does not represent a borrowing, but rather is in the nature
of a performance bond or good-faith deposit that is returned to the Fund at the
termination of the transaction if all contractual obligations have been
satisfied.  Under certain circumstances, such as periods of high volatility,
the Fund may be required by an exchange to increase the level of its initial
margin payment, and initial margin requirements might be increased generally in
the future by regulatory action.

     Subsequent "variation margin" payments are made to and from the futures
broker daily as the value of the futures position varies, a process known as
"marking to market."  Variation margin does not involve borrowing, but rather
represents a daily settlement of the Fund's obligations to or from a futures
broker.  When the Fund purchases an option on a future, the premium paid plus
transaction costs is all that is at risk.  In contrast, when the Fund purchases
or sells a futures contract or writes a call or put option thereon, it is
subject to daily variation margin calls that could be substantial in the event
of adverse price movements.  If the Fund has insufficient cash to meet daily
variation margin requirements, it might need to sell securities at a time when
such sales are disadvantageous.  Purchasers and sellers of futures positions
and options on futures can enter into offsetting closing transactions by
selling or purchasing, respectively, an instrument identical to the instrument
held or written.  Positions in futures and options on futures may be closed
only on an exchange or board of trade that provides a secondary market.  The
Fund intends to enter into futures transactions only on exchanges or boards of
trade where there appears to be a liquid secondary market.  However, there can
be no assurance that such a market will exist for a particular contract at a
particular time.

     Under certain circumstances, futures exchanges may establish daily limits
on the amount that the price of a future or option on a futures contract can
vary from the previous day's settlement price; once that limit is reached, no
trades may be made that day at a price beyond the limit.  Daily price limits do
not limit potential losses because prices could move to the daily limit for
several consecutive days with little or no trading, thereby preventing
liquidation of unfavorable positions.

     If the Fund were unable to liquidate a futures or option on a futures
contract position due to the absence of a liquid secondary market or the
imposition of price limits, it could incur substantial losses.  The Fund would
continue to be subject to market risk with respect to the position.  In
addition, except in the case of purchased options, the Fund would continue to
be required to make daily variation margin payments and might be required to
maintain the position being hedged by the future or option or to maintain cash
or securities in a segregated account.

     Certain characteristics of the futures market might increase the risk that
movements in the prices of futures contracts or options on futures contracts
might not correlate perfectly with movements in the prices of the investments
being hedged.  For example, all participants in the futures and options on
futures contracts markets are subject to daily variation margin calls and might
be compelled to liquidate futures or options on futures contracts positions
whose prices are moving unfavorably to avoid being subject to further calls.
These liquidations could increase price volatility of the instruments and
distort the normal price relationship between the futures or options and the
investments being hedged.  Also, because initial margin deposit requirements in
the futures markets are less onerous than margin requirements in the securities
markets, there might be

                                     - 11 -

<PAGE>   51

increased participation by speculators in the future markets.  This
participation also might cause temporary price distortions.  In addition,
activities of large traders in both the futures and securities markets
involving arbitrage, "program trading" and other investment strategies might
result in temporary price distortions.

     FOREIGN CURRENCIES.  The Fund may purchase and sell foreign currency on a
spot basis, and may use currency-related derivatives instruments such as
options on foreign currencies, futures on foreign currencies, options on
futures on foreign currencies and forward currency contracts (i.e., an
obligation to purchase or sell a specific currency at a specified future date,
which may be any fixed number of days from the contract date agreed upon by the
parties, at a price set at the time the contract is entered into).  The Fund
may use these instruments for hedging or any other lawful purpose consistent
with their respective investment objectives, including transaction hedging,
anticipatory hedging, cross hedging, proxy hedging, and position hedging.  The
Fund's use of currency-related derivative instruments will be directly related
to the Fund's current or anticipated portfolio securities, and the Fund may
engage in transactions in currency-related derivative instruments as a means to
protect against some or all of the effects of adverse changes in foreign
currency exchange rates on their portfolio investments.  In general, if the
currency in which a portfolio investment is denominated appreciates against the
U.S. dollar, the dollar value of the security will increase.  Conversely, a
decline in the exchange rate of the currency would adversely affect the value
of the portfolio investment expressed in U.S. dollars.

     For example, the Fund might use currency-related derivative instruments to
"lock in" a U.S. dollar price for a portfolio investment, thereby enabling the
Fund to protect itself against a possible loss resulting from an adverse change
in the relationship between the U.S. dollar and the subject foreign currency
during the period between the date the security is purchased or sold and the
date on which payment is made or received.  The Fund also might use
currency-related derivative instruments when the Advisor believes that one
currency may experience a substantial movement against another currency,
including the U.S. dollar, and it may use currency-related derivative
instruments to sell or buy the amount of the former foreign currency,
approximating the value of some or all of the Fund's portfolio securities
denominated in such foreign currency.  Alternatively, where appropriate, the
Fund may use currency-related derivative instruments to hedge all or part of
its foreign currency exposure through the use of a basket of currencies or a
proxy currency where such currency or currencies act as an effective proxy for
other currencies.  The use of this basket hedging technique may be more
efficient and economical than using separate currency-related derivative
instruments for each currency exposure held by the Fund.  Furthermore,
currency-related derivative instruments may be used for short hedges - for
example, the Fund may sell a forward currency contract to lock in the U.S.
dollar equivalent of the proceeds from the anticipated sale of  a security
denominated in a foreign currency.

     In addition, the Fund may use a currency-related derivative instrument to
shift exposure to foreign currency fluctuations from one foreign country to
another foreign country where the Advisor believes that the foreign currency
exposure purchased will appreciate relative to the U.S. dollar and thus better
protect the Fund against the expected decline in the foreign currency exposure
sold.  For example, if the Fund owns securities denominated in a foreign
currency and the Advisor believes that currency will decline, it might enter
into a forward contract to sell an appropriate amount of the first foreign
currency, with payment to be made in a second foreign currency that the Advisor
believes would better protect the Fund against the decline in the first
security than would a U.S. dollar exposure.  Hedging transactions that use two
foreign currencies are sometimes referred to as "cross hedges."  The effective
use of currency-related derivative instruments by the Fund in a cross hedge is
dependent upon a correlation between price movements of the two currency
instruments and the underlying security involved, and the use of two currencies
magnifies the risk that movements in the price of one instrument may not
correlate or may correlate unfavorably with the foreign currency being hedged.
Such a lack of correlation might occur due to factors unrelated to the value of
the currency instruments used or investments being hedged, such as speculative
or other pressures on the markets in which these instruments are traded.

     The Fund also might seek to hedge against changes in the value of a
particular currency when no hedging instruments on that currency are available
or such hedging instruments are more expensive than certain other hedging
instruments.  In such cases, the Fund may hedge against price movements in that
currency by entering into transactions using currency-related derivative
instruments on another foreign currency or a basket of currencies, the values
of which the Advisor believes will have a high degree of positive correlation
to the value of the currency being hedged.  The risk that movements in the
price of the hedging instrument will not correlate perfectly with movements in
the price of the currency being hedged is magnified when this strategy is used.


                                     - 12 -

<PAGE>   52


     The use of currency-related derivative instruments by the Fund involves a
number of risks.  The value of currency-related derivative instruments depends
on the value of the underlying currency relative to the U.S. dollar.  Because
foreign currency transactions occurring in the interbank market might involve
substantially larger amounts than those involved in the use of such derivative
instruments, the Fund could be disadvantaged by having to deal in the odd lot
market (generally consisting of transactions of less than $1 million) for the
underlying foreign currencies at prices that are less favorable than for round
lots (generally consisting of transactions of greater than $1 million).

     There is no systematic reporting of last sale information for foreign
currencies or any regulatory requirement that quotations available through
dealers or other market sources be firm or revised on a timely basis.
Quotation information generally is representative of very large transactions in
the interbank market and thus might not reflect odd-lot transactions where
rates might be less favorable.  The interbank market in foreign currencies is a
global, round-the-clock market.  To the extent the U.S. options or futures
markets are closed while the markets for the underlying currencies remain open,
significant price and rate movements might take place in the underlying markets
that cannot be reflected in the markets for the derivative instruments until
they re-open.

     Settlement of transactions in currency-related derivative instruments
might be required to take place within the country issuing the underlying
currency.  Thus, the Fund might be required to accept or make delivery of the
underlying foreign currency in accordance with any U.S. or foreign regulations
regarding the maintenance of foreign banking arrangements by U.S. residents and
might be required to pay any fees, taxes and charges associated with such
delivery assessed in the issuing country.

     When the Fund engages in a transaction in a currency-related derivative
instrument, it relies on the counterparty to make or take delivery of the
underlying currency at the maturity of the contract or otherwise complete the
contract.  In other words, the Fund will be subject to the risk that a loss may
be sustained by the Fund as a result of the failure of the counterparty to
comply with the terms of the transaction.  The counterparty risk for
exchange-traded instruments is generally less than for privately-negotiated or
OTC currency instruments, since generally a clearing agency, which is the
issuer or counterparty to each instrument, provides a guarantee of performance.
For privately-negotiated instruments, there is no similar clearing agency
guarantee.  In all transactions, the Fund will bear the risk that the
counterparty will default, and this could result in a loss of the expected
benefit of the transaction and possibly other losses to the Fund.  The Fund
will enter into transactions in currency-related derivative instruments only
with counterparties that the Advisor reasonably believes are capable of
performing under the contract.

     Purchasers and sellers of currency-related derivative instruments may
enter into offsetting closing transactions by selling or purchasing,
respectively, an instrument identical to the instrument purchased or sold.
Secondary markets generally do not exist for forward currency contracts, with
the result that closing transactions generally can be made for forward currency
contracts only by negotiating directly with the counterparty.  Thus, there can
be no assurance that the Fund will in fact be able to close out a forward
currency contract (or any other currency-related derivative instrument) at a
time and price favorable to the Fund.  In addition, in the event of insolvency
of the counterparty, the Fund might be unable to close out a forward currency
contract at any time prior to maturity.  In the case of an exchange-traded
instrument, the Fund will be able to close the position out only on an exchange
which provides a market for the instruments.  The ability to establish and
close out positions on an exchange is subject to the maintenance of a liquid
market, and there can be no assurance that a liquid market will exist for any
instrument at any specific time.  In the case of a privately-negotiated
instrument, the Fund will be able to realize the value of the instrument only
by entering into a closing transaction with the issuer or finding a third party
buyer for the instrument.  While the Fund will enter into privately-negotiated
transactions only with entities who are expected to be capable of entering into
a closing transaction, there can be no assurance that the Fund will in fact be
able to enter into such closing transactions.

     The precise matching of currency-related derivative instrument amounts and
the value of the portfolio securities involved generally will not be possible
because the value of such securities, measured in the foreign currency, will
change after the currency-related derivative instrument position has been
established.  Thus, the Fund might need to purchase or sell foreign currencies
in the spot (cash) market.  The projection of short-term currency market
movements is extremely difficult, and the successful execution of a short-term
hedging strategy is highly uncertain.

     Permissible foreign currency options will include options traded primarily
in the OTC market.  Although options on foreign currencies are traded primarily
in the OTC market, the Fund will normally purchase or sell OTC options on
foreign

                                     - 13 -

currency only when the Advisor reasonably believes a liquid secondary market
will exist for a particular option at any specific time.

     There will be a cost to the Fund of engaging in transactions in
currency-related derivative instruments that will vary with factors such as the
contract or currency involved, the length of the contract period and the market
conditions then prevailing.  The Fund using these instruments may have to pay a
fee or commission or, in cases where the instruments are entered into on a
principal basis, foreign exchange dealers or other counterparties will realize
a profit based on the difference ("spread") between the prices at which they
are buying and selling various currencies.  Thus, for example, a dealer may
offer to sell a foreign currency to the Fund at one rate, while offering a
lesser rate of exchange should the Fund desire to resell that currency to the
dealer.

     When required by the SEC guidelines, the Fund will set aside permissible
liquid assets in segregated accounts or otherwise cover their respective
potential obligations under currency-related derivatives instruments.  To the
extent the Fund's assets are so set aside, they cannot be sold while the
corresponding currency position is open, unless they are replaced with similar
assets.  As a result, if a large portion of the Fund's assets are so set aside,
this could impede portfolio management or the Fund's ability to meet redemption
requests or other current obligations.

     The Advisor's decision to engage in a transaction in a particular
currency-related derivative instrument will reflect the Advisor's judgment that
the transaction will provide value to the Fund and its shareholders and is
consistent with the Fund's objectives and policies.  In making such a judgment,
the Advisor will analyze the benefits and risks of the transaction and weigh
them in the context of the Fund's entire portfolio and objectives.  The
effectiveness of any transaction in a currency-related derivative instrument is
dependent on a variety of factors, including the Advisor's skill in analyzing
and predicting currency values and upon a correlation between price movements
of the currency instrument and the underlying security.  There might be
imperfect correlation, or even no correlation, between price movements of an
instrument and price movements of investments being hedged.  Such a lack of
correlation might occur due to factors unrelated to the value of the
investments being hedged, such as speculative or other pressures on the markets
in which these instruments are traded.  In addition, the Fund's use of
currency-related derivative instruments is always subject to the risk that the
currency in question could be devalued by the foreign government.  In such a
case, any long currency positions would decline in value and could adversely
affect any hedging position maintained by the Fund.

     The Fund's dealing in currency-related derivative instruments will
generally be limited to the transactions described  above.  However, the Fund
reserves the right to use currency-related derivatives instruments for
different purposes and under different circumstances.  Of course, the Fund is
not required to use currency-related derivatives instruments and will not do so
unless deemed appropriate by the Advisor.  It also should be realized that use
of these instruments does not eliminate, or protect against, price movements in
the Fund's securities that are attributable to other (i.e., non-currency
related) causes.  Moreover, while the use of currency-related derivatives
instruments may reduce the risk of loss due to a decline in the value of a
hedged currency, at the same time the use of these instruments tends to limit
any potential gain which may result from an increase in the value of that
currency.

     SWAP AGREEMENTS.  The Fund may enter into interest rate, securities index,
commodity, or security and currency exchange rate swap agreements for any
lawful purpose consistent with the Fund's investment objective, such as for the
purpose of attempting to obtain or preserve a particular desired return or
spread at a lower cost to the Fund than if the Fund had invested directly in an
instrument that yielded that desired return or spread.  The Fund also may enter
into swaps in order to protect against an increase in the price of, or the
currency exchange rate applicable to, securities that the Fund anticipates
purchasing at a later date.  Swap agreements are two-party contracts entered
into primarily by institutional investors for periods ranging from a few weeks
to several years.  In a standard "swap" transaction, two parties agree to
exchange the returns (or differentials in rates of return) earned or realized
on particular predetermined investments or instruments.  The gross returns to
be exchanged or "swapped" between the parties are calculated with respect to a
"notional amount," i.e., the return on or increase in value of a particular
dollar amount invested at a particular interest rate, in a particular foreign
currency, or in a "basket" of securities representing a particular index.  Swap
agreements may include interest rate caps, under which, in return for a
premium, one party agrees to make payments to the other to the extent that
interest rates exceed a specified rate, or "cap;" interest rate floors, under
which, in return for a premium, one party agrees to make payments to the other
to the extent that interest rates fall below a specified level, or "floor;" and
interest rate collars, under which a party sells a cap and purchases a floor,
or vice versa, in an attempt to protect itself against interest rate movements
exceeding given minimum or maximum levels.

                                     - 14 -

<PAGE>   54



     The "notional amount" of the swap agreement is the agreed upon basis for
calculating the obligations that the parties to a swap agreement have agreed to
exchange.  Under most swap agreements entered into by the Fund, the obligations
of the parties would be exchanged on a "net basis."  Consequently, the Fund's
obligation (or rights) under a swap agreement will generally be equal only to
the net amount to be paid or received under the agreement based on the relative
values of the positions held by each party to the agreement (the "net amount").
The Fund's obligation under a swap agreement will be accrued daily (offset
against amounts owed to the Fund) and any accrued but unpaid net amounts owed
to a swap counterparty will be covered by the maintenance of a segregated
account consisting of cash, or liquid high grade debt obligations.

     Whether the Fund's use of swap agreements will be successful in furthering
its investment objective will depend, in part, on the Advisor's ability to
predict correctly whether certain types of investments are likely to produce
greater returns than other investments.  Swap agreements may be considered to
be illiquid.  Moreover, the Fund bears the risk of loss of the amount expected
to be received under a swap agreement in the event of the default or bankruptcy
of a swap agreement counterparty.  Certain restrictions imposed on the Fund by
the Internal Revenue Code may limit the Fund's ability to use swap agreements.
The swaps market is largely unregulated.

     The Fund will enter swap agreements only with counterparties that the
Advisor reasonably believes are capable of performing under the swap
agreements.  If there is a default by the other party to such a transaction,
the Fund will have to rely on its contractual remedies (which may be limited by
bankruptcy, insolvency or similar laws) pursuant to the agreements related to
the transaction.

     ADDITIONAL DERIVATIVE INSTRUMENTS AND STRATEGIES.  In addition to the
derivative instruments and strategies described above and in the Fund's
Prospectus, the Advisor expects to discover additional derivative instruments
and other hedging or risk management techniques.  The Advisor may utilize these
new derivative instruments and techniques to the extent that they are
consistent with a Fund's investment objective and permitted by the Fund's
investment limitations, operating policies, and applicable regulatory
authorities.

FOREIGN INVESTMENT COMPANIES

     The Fund may invest, to a limited extent, in foreign investment
companies.  Some of the countries in which the Fund invests may not permit
direct investment by outside investors.  Investments in such countries may
only be permitted through foreign government-approved or -authorized
investment vehicles, which may include other investment companies.  In
addition, it may be less expensive and more expedient for the Fund to invest
in a foreign investment company in a country which permits direct foreign
investment.  Investing through such vehicles may involve frequent or layered
fees or expenses and may also be subject to limitation under the 1940 Act.
Under the 1940 Act, the Fund may invest up to 10% of its assets in shares of
other investment companies and up to 5% of its assets in any one investment
company as long as the investment does not represent more than 3% of the
voting stock of the acquired investment company.  The Fund does not intend to
invest in such investment companies unless, in the judgment of the Advisor,
the potential benefits of such investments justify the payment of any
associated fees and expenses.

FOREIGN SECURITIES

     Investing in foreign securities involves a series of risks not present in
investing in U.S. securities.  Many of the foreign securities held by the Fund
will not be registered with the Securities and Exchange Commission (the "SEC"),
nor will the foreign issuers be subject to SEC reporting requirements.
Accordingly, there may be less publicly available information concerning
foreign issuers of securities held by the Fund than is available concerning
U.S. companies.  Disclosure and regulatory standards in many respects are less
stringent in emerging market countries than in the U.S.  and other major
markets. There also may be a lower level of monitoring and regulation of
emerging markets and the activities of investors in such markets, and
enforcement of existing regulations may be extremely limited.  Foreign
companies, and in particular, companies in smaller and emerging capital markets
are not generally subject to uniform accounting, auditing and financial
reporting standards, or to other regulatory requirements comparable to those
applicable to U.S. companies.  The Fund's net investment income and capital
gains from its foreign investment activities may be subject to non-U.S.
withholding taxes.

                                     - 15 -

<PAGE>   55



     The costs attributable to foreign investing that the Fund must bear
frequently are higher than those attributable to domestic investing; this is
particularly true with respect to emerging capital markets.  For example, the
cost of maintaining custody of foreign securities exceeds custodian costs for
domestic securities, and transaction and settlement costs of foreign investing
also frequently are higher than those attributable to domestic investing.
Costs associated with the exchange of currencies also make foreign investing
more expensive than domestic investing.  Investment income on certain foreign
securities in which the Funds may invest may be subject to foreign withholding
or other government taxes that could reduce the return of these securities.
Tax treaties between the United States and foreign countries, however, may
reduce or eliminate the amount of foreign tax to which the Fund would be
subject.

     Foreign markets also have different clearance and settlement procedures,
and in certain markets there have been times when settlements have failed to
keep pace with the volume of securities transactions, making it difficult to
conduct such transactions.  Delays in settlement could result in temporary
periods when assets of the Fund are uninvested and no return is earned thereon.
The inability of the Fund to make intended security purchases due to
settlement problems could cause the Fund to miss investment opportunities.
Inability to dispose of a portfolio security due to settlement problems could
result either in losses to the Fund due to subsequent declines in the value of
such portfolio security or, if the Fund has entered into a contract to sell the
security, could result in possible liability to the purchaser.

HIGH-YIELD (HIGH-RISK) SECURITIES

     IN GENERAL.  The Fund may invest without limitation in non-investment
grade debt obligations.  Non-investment grade debt obligations (hereinafter
referred to as "lower-quality securities") include (i) bonds rated as low as C
by Moody's Investors Service, Inc.  ("Moody's"), Standard & Poor's Ratings
Group ("S&P"), or Fitch Investors Service, Inc. ("Fitch"), or CCC by Duff &
Phelps, Inc. ("D&P"); (ii) commercial paper rated as low as C by S&P, Not Prime
by Moody's, or Fitch 4 by Fitch; and (iii) unrated debt obligations of
comparable quality.  Lower-quality securities, while generally offering higher
yields than investment grade securities with similar maturities, involve
greater risks, including the possibility of default or bankruptcy. They are
regarded as predominantly speculative with respect to the issuer's capacity to
pay interest and repay principal.  The special risk considerations in
connection with investments in these securities are discussed below.  Refer to
the Appendix for a discussion of securities ratings.

     EFFECT OF INTEREST RATES AND ECONOMIC CHANGES.  The lower-quality and
comparable unrated security market is relatively new and its growth has
paralleled a long economic expansion.  As a result, it is not clear how this
market may withstand a prolonged recession or economic downturn.  Such
conditions could severely disrupt the market for and adversely affect the value
of such securities.

     All interest-bearing securities typically experience appreciation when
interest rates decline and depreciation when interest rates rise.  The market
values of lower-quality and comparable unrated securities tend to reflect
individual corporate developments to a greater extent than do higher rated
securities, which react primarily to fluctuations in the general level of
interest rates.  Lower-quality and comparable unrated securities also tend to
be more sensitive to economic conditions than are higher-rated securities.  As
a result, they generally involve more credit risks than securities in the
higher-rated categories.  During an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower-quality and comparable
unrated securities may experience financial stress and may not have sufficient
revenues to meet their payment obligations.  The issuer's ability to service
its debt obligations may also be adversely affected by specific corporate
developments, the issuer's inability to meet specific projected business
forecasts or the unavailability of additional financing. The risk of loss due
to default by an issuer of these securities is significantly greater than
issuers of higher-rated securities because such securities are generally
unsecured and are often subordinated to other creditors.  Further, if the
issuer of a lower-quality or comparable unrated security defaulted, the Fund
might incur additional expenses to seek recovery.  Periods of economic
uncertainty and changes would also generally result in increased volatility in
the market prices of these securities and thus in the Fund's net asset value.

     As previously stated, the value of a lower-quality or comparable unrated
security will decrease in a rising interest rate market and accordingly, so
will the Fund's net asset value.  If the Fund experiences unexpected net
redemptions in such a market, it may be forced to liquidate a portion of its
portfolio securities without regard to their investment merits.  Due to the
limited liquidity of lower-quality and comparable unrated securities (discussed
below), the Fund may be forced to liquidate

                                     - 16 -

<PAGE>   56

these securities at a substantial discount.  Any such liquidation would force
the Fund to sell the more liquid portion of its portfolio.

     PAYMENT EXPECTATIONS.  Lower-quality and comparable unrated securities
typically contain redemption, call or prepayment provisions which permit the
issuer of such securities containing such provisions to, at its discretion,
redeem the securities.  During periods of falling interest rates, issuers of
these securities are likely to redeem or prepay the securities and refinance
them with debt securities with a lower interest rate.  To the extent an issuer
is able to refinance the securities, or otherwise redeem them, the Fund may
have to replace the securities with a lower yielding security, which would
result in a lower return for the Fund.

     CREDIT RATINGS.  Credit ratings issued by credit rating agencies are
designed to evaluate the safety of principal and interest payments of rated
securities.  They do not, however, evaluate the market value risk of
lower-quality securities and, therefore, may not fully reflect the true risks
of an investment.  In addition, credit rating agencies may or may not make
timely changes in a rating to reflect changes in the economy or in the
condition of the issuer that affect the market value of the security.
Consequently, credit ratings are used only as a preliminary indicator of
investment quality.  Investments in lower-quality and comparable unrated
obligations will be more dependent on the Advisor's credit analysis than would
be the case with investments in investment-grade debt obligations.  The Advisor
employs its own credit research and analysis, which includes a study of
existing debt, capital structure, ability to service debt and to pay dividends,
the issuer's sensitivity to economic conditions, its operating history and the
current trend of earnings.  The Advisor continually monitors the investments in
the Fund's portfolio and carefully evaluates whether to dispose of or to retain
lower-quality and comparable unrated securities whose credit ratings or credit
quality may have changed.

     LIQUIDITY AND VALUATION.  The Fund may have difficulty disposing of
certain lower-quality and comparable unrated securities because there may be a
thin trading market for such securities.  Because not all dealers maintain
markets in all lower-quality and comparable unrated securities, there is no
established retail secondary market for many of these securities.  The Fund
anticipates that such securities could be sold only to a limited number of
dealers or institutional investors.  To the extent a secondary trading market
does exist, it is generally not as liquid as the secondary market for
higher-rated securities.  The lack of a liquid secondary market may have an
adverse impact on the market price of the security.  As a result, the Fund's
asset value and ability to dispose of particular securities, when necessary to
meet the Fund's liquidity needs or in response to a specific economic event,
may be impacted.  The lack of a liquid secondary market for certain securities
may also make it more difficult for the Fund to obtain accurate market
quotations for purposes of valuing the Fund's portfolio.  Market quotations are
generally available on many lower-quality and comparable unrated issues only
from a limited number of dealers and may not necessarily represent firm bids of
such dealers or prices for actual sales.  During periods of thin trading, the
spread between bid and asked prices is likely to increase significantly.  In
addition, adverse publicity and investor perceptions, whether or not based on
fundamental analysis, may decrease the values and liquidity of lower-quality
and comparable unrated securities, especially in a thinly traded market.

     LEGISLATION.  Legislation may be adopted, from time to time designed to
limit the use of certain lower-quality and comparable unrated securities by
certain issuers.  It is anticipated that if additional legislation is enacted
or proposed, it could have a material affect on the value of these securities
and the existence of a secondary trading market for the securities.

ILLIQUID SECURITIES

     The Fund may invest in illiquid securities (i.e., securities that are not
readily marketable).  However, the Fund will not acquire illiquid securities
if, as a result, they would comprise more than 15% of the value of the Fund's
net assets (or such other amounts as may be permitted under the 1940 Act).
However, as a matter of internal policy, the Advisor intends to limit the
Fund's investments in illiquid securities to 10% of its net assets.

     The Board of Directors of the Fund, or its delegate, has the ultimate
authority to determine, to the extent permissible under the federal securities
laws, which securities are illiquid for purposes of this limitation.  Certain
securities exempt from registration or issued in transactions exempt from
registration under the Securities Act of 1933, as amended (the "Securities
Act"),  such as securities that may be resold to institutional investors under
Rule 144A under the Securities Act and Section 4(2) commercial paper, may be
considered liquid under guidelines adopted by the Fund's Board of Directors.

                                     - 17 -

<PAGE>   57



     The Board of Directors of the Fund has delegated to the Advisor the
day-to-day determination of the liquidity of a security, although it has
retained oversight and ultimate responsibility for such determinations.  The
Board of Directors has directed the Advisor to look to such factors as (i) the
frequency of trades or quotes for a security, (ii) the number of dealers
willing to purchase or sell the security and number of potential buyers, (iii)
the willingness of dealers to undertake to make a market in the security, (iv)
the nature of the security and nature of the marketplace trades, such as the
time needed to dispose of the security, the method of soliciting offers, and
the mechanics of transfer, (v) the likelihood that the security's marketability
will be maintained throughout the anticipated holding period, and (vi) any
other relevant factors.  The Advisor may determine 4(2) commercial paper to be
liquid if (i) the 4(2) commercial paper is not traded flat or in default as to
principal and interest, (ii) the 4(2) commercial paper is rated in one of the
two highest rating categories by at least two nationally rated statistical
rating organizations ("NRSRO"), or if only one NRSRO rates the security, by
that NRSRO, or is determined by the Advisor to be of equivalent quality, and
(iii) the Advisor considers the trading market for the specific security taking
into account all relevant factors.  A foreign security may be considered liquid
by the Advisor (despite its restricted nature under the Securities Act) if the
security can be freely traded in a foreign securities market and all the facts
and circumstances support a finding of liquidity.

     Restricted securities may be sold only in privately negotiated
transactions or in a public offering with respect to which a registration
statement is in effect under the Securities Act.  Where registration is
required, the Fund may be obligated to pay all or part of the registration
expenses and a considerable period may elapse between the time of the decision
to sell and the time the Fund may be permitted to sell a security under an
effective registration statement.  If, during such a period, adverse market
conditions were to develop, the Fund might obtain a less favorable price than
prevailed when it decided to sell.  Restricted securities will be priced at
fair value as determined in good faith by the Board of Directors of the Fund.
If through the appreciation of restricted securities or the depreciation of
unrestricted securities, the Fund should be in a position where more than 15%
of the value of its net assets are invested in illiquid securities, including
restricted securities which are not readily marketable (except for 144A
Securities and 4(2) commercial paper deemed to be liquid by the Advisor), the
Fund will take such steps as is deemed advisable, if any, to protect liquidity.

     The Fund may sell over-the-counter ("OTC") options and, in connection
therewith, segregate assets or cover its obligations with respect to OTC
options written by the Fund.  The assets used as cover for OTC options written
by the Fund will be considered illiquid unless the OTC options are sold to
qualified dealers who agree that the Fund may repurchase any OTC option it
writes at a maximum price to be calculated by a formula set forth in the option
agreement.  The cover for an OTC option written subject to this procedure would
be considered illiquid only to the extent that the maximum repurchase price
under the formula exceeds the intrinsic value of the option.

LENDING OF PORTFOLIO SECURITIES

     The Fund is authorized to lend up to 33 1/3% of the total value of its
portfolio securities to broker-dealers or institutional investors that the
Advisor deems qualified, but only when the borrower maintains with the Fund's
custodian bank collateral either in cash or money market instruments in an
amount at least equal to the market value of the securities loaned, plus
accrued interest and dividends, determined on a daily basis and adjusted
accordingly.  Although the Fund is authorized to lend, the Fund does not
presently intend to engage in lending.  In determining whether to lend
securities to a particular broker-dealer or institutional investor, the Advisor
will consider, and during the period of the loan will monitor, all relevant
facts and circumstances, including the creditworthiness of the borrower.  The
Fund will retain authority to terminate any loans at any time.  The Fund may
pay reasonable administrative and custodial fees in connection with a loan and
may pay a negotiated portion of the interest earned on the cash or money market
instruments held as collateral to the borrower or placing broker.  The Fund
will receive reasonable interest on the loan or a flat fee from the borrower
and amounts equivalent to any dividends, interest or other distributions on the
securities loaned.  The Fund will retain record ownership of loaned securities
to exercise beneficial rights, such as voting and subscription rights and
rights to dividends, interest or other distributions, when retaining such
rights is considered to be in a Fund's interest.

LOAN INTERESTS

     The Fund may acquire a loan interest (a "Loan Interest").  A Loan Interest
is typically originated, negotiated, and structured by a U.S.  or foreign
commercial bank, insurance company, finance company, or other financial
institution (the "Agent") for a lending syndicate of financial institutions.
The Agent typically administers and enforces the loan on behalf of the other
lenders in the syndicate.  In addition, an institution, typically but not
always the Agent (the "Collateral Bank"), holds

                                     - 18 -

<PAGE>   58

collateral (if any) on behalf of the lenders.  These Loan Interests may take
the form of participation interests in, assignments of or novations of a loan
during its secondary distribution, or direct interests during a primary
distribution.  Such Loan Interests may be acquired from U.S.  or foreign banks,
insurance companies, finance companies, or other financial institutions who
have made loans or are members of a lending syndicate or from other holders of
Loan Interests.  The Fund may also acquire Loan Interests under which the Fund
derives its rights directly from the borrower.  Such Loan Interests are
separately enforceable by the Fund against the borrower and all payments of
interest and principal are typically made directly to the Fund from the
borrower.  In the event that the Fund and other lenders become entitled to take
possession of shared collateral, it is anticipated that such collateral would
be held in the custody of a Collateral Bank for their mutual benefit.  The Fund
may not act as an Agent, a Collateral Bank, a guarantor or sole negotiator or
structurer with respect to a loan.

     The Advisor will analyze and evaluate the financial condition of the
borrower in connection with the acquisition of any Loan Interest.  The Advisor
also analyzes and evaluates the financial condition of the Agent and, in the
case of Loan Interests in which the Fund does not have privity with the
borrower, those institutions from or through whom the Fund derives its rights
in a loan (the "Intermediate Participants").

     In a typical loan the Agent administers the terms of the loan agreement.
In such cases, the Agent is normally responsible for the collection of
principal and interest payments from the borrower and the apportionment of
these payments to the credit of all institutions which are parties to the loan
agreement.  The Fund will generally rely upon the Agent or an Intermediate
Participant to receive and forward to the Fund its portion of the principal and
interest payments on the loan.  Furthermore, unless under the terms of a
participation agreement the Fund has direct recourse against the borrower, the
Fund will rely on the Agent and the other members of the lending syndicate to
use appropriate credit remedies against the borrower.  The Agent is typically
responsible for monitoring compliance with covenants contained in the loan
agreement based upon reports prepared by the borrower.  The seller of the Loan
Interest usually does, but is often not obligated to, notify holders of Loan
Interests of any failures of compliance.  The Agent may monitor the value of
the collateral and, if the value of the collateral declines, may accelerate the
loan, may give the borrower an opportunity to provide additional collateral or
may seek other protection for the benefit of the participants in the loan.  The
Agent is compensated by the borrower for providing these services under a loan
agreement, and such compensation may include special fees paid upon structuring
and funding the loan and other fees paid on a continuing basis.  With respect
to Loan Interests for which the Agent does not perform such administrative and
enforcement functions, the Fund will perform such tasks on its own behalf,
although a Collateral Bank will typically hold any collateral on behalf of the
Fund and the other lenders pursuant to the applicable loan agreement.

     A financial institution's appointment as Agent may usually be terminated
in the event that it fails to observe the requisite standard of care or becomes
insolvent, enters Federal Deposit Insurance Corporation ("FDIC") receivership,
or, if not FDIC insured, enters into bankruptcy proceedings.  A successor Agent
would generally be appointed to replace the terminated Agent, and assets held
by the Agent under the loan agreement should remain available to holders of
Loan Interests.  However, if assets held by the Agent for the benefit of the
Fund were determined to be subject to the claims of the Agent's general
creditors, the Fund might incur certain costs and delays in realizing payment
on a loan interest, or suffer a loss of principal and/or interest.  In
situations involving Intermediate Participants similar risks may arise.

     Purchasers of Loan Interests depend primarily upon the creditworthiness of
the borrower for payment of principal and interest.  If the Fund does not
receive scheduled interest or principal payments on such indebtedness, the
Fund's share price and yield could be adversely affected.  Loans that are fully
secured offer the Fund more protections than an unsecured loan in the event of
non-payment of scheduled interest or principal.  However, there is no assurance
that the liquidation of collateral from a secured loan would satisfy the
borrower's obligation, or that the collateral can be liquidated.  Indebtedness
of borrowers whose creditworthiness is poor involves substantially greater
risks, and may be highly speculative.  Borrowers that are in bankruptcy or
restructuring may never pay off their indebtedness, or may pay only a small
fraction of the amount owed.  Direct indebtedness of developing countries will
also involve a risk that the governmental entities responsible for the
repayment of the debt may be unable, or unwilling, to pay interest and repay
principal when due.

MATURITY

     The Fund's average portfolio maturity represents an average based on the
actual stated maturity dates of the debt securities in the Fund's portfolio,
except that (i) variable-rate securities are deemed to mature at the next

backed securities is determined on an "expected life" basis as determined by
the Advisor, and (iv) securities being hedged with futures contracts may be
deemed to have a longer maturity, in the case of purchases of futures
contracts, and a shorter maturity, in the case of sales of futures contracts,
than they would otherwise be deemed to have.  In addition, a security that is
subject to redemption at the option of the issuer on a particular date (the
"call date"), which is prior to the security's stated maturity, may be deemed
to mature on the call date rather than on its stated maturity date.  The call
date of a security will be used to calculate average portfolio maturity when
the Advisor reasonably anticipates, based upon information available to it,
that the issuer will exercise its right to redeem the security.  The average
portfolio maturity of the Fund is dollar-weighted based upon the market value
of the Fund's securities at the time of the calculation.

MORTGAGE- AND ASSET-BACKED SECURITIES

     Mortgage-backed securities represent direct or indirect participations in,
or are secured by and payable from, mortgage loans secured by real property,
and include single- and multi-class pass-through securities and collateralized
mortgage obligations.  Such securities may be issued or guaranteed by U.S.
government agencies or instrumentalities, such as the Government National
Mortgage Association and the Federal National Mortgage Association, or by
private issuers, generally originators and investors in mortgage loans,
including savings associations, mortgage bankers, commercial banks, investment
bankers, and special purpose entities (collectively, "private lenders").
Mortgage-backed securities issued by private lenders may be supported by pools
of mortgage loans or other mortgage-backed securities that are guaranteed,
directly or indirectly, by the U.S.  government or one of its agencies or
instrumentalities, or they may be issued without any governmental guarantee of
the underlying mortgage assets but with some form of non-governmental credit
enhancement.

     Asset-backed securities have structural characteristics similar to
mortgage-backed securities.  Asset-backed debt obligations represent direct or
indirect participation in, or secured by and payable from, assets such as motor
vehicle installment sales contracts, other installment loan contracts, home
equity loans, leases of various types of property, and receivables from credit
card or other revolving credit arrangements.  The credit quality of most
asset-backed securities depends primarily on the credit quality of the assets
underlying such securities, how well the entity issuing the security is
insulated from the credit risk of the originator or any other affiliated
entities, and the amount and quality of any credit enhancement of the
securities.  Payments or distributions of principal and interest on
asset-backed debt obligations may be supported by non-governmental credit
enhancements including letters of credit, reserve funds, overcollateralization,
and guarantees by third parties.  The market for privately issued asset-backed
debt obligations is smaller and less liquid than the market for government
sponsored mortgage-backed securities.

     The rate of principal payment on mortgage- and asset-backed securities
generally depends on the rate of principal payments received on the underlying
assets which in turn may be affected by a variety of economic and other
factors.  As a result, the yield on any mortgage- and asset-backed security is
difficult to predict with precision and actual yield to maturity may be more or
less than the anticipated yield to maturity. The yield characteristics of
mortgage- and asset-backed securities differ from those of traditional debt
securities.  Among  the principal differences are that interest and principal
payments are made more frequently on mortgage-and asset-backed securities,
usually monthly, and that principal may be prepaid at any time because the
underlying mortgage loans or other assets generally may be prepaid at any time.
As a result, if the Fund purchases these securities at a premium, a prepayment
rate that is faster than expected will reduce yield to maturity, while a
prepayment rate that is slower than expected will have the opposite effect of
increasing the yield to maturity.  Conversely, if the Fund purchases these
securities at a discount, a prepayment rate that is faster than expected will
increase yield to maturity, while a prepayment rate that is slower than
expected will reduce yield to maturity.  Amounts available for reinvestment by
the Fund are likely to be greater during a period of declining interest rates
and, as a result, are likely to be reinvested at lower interest rates than
during a period of rising interest rates.  Accelerated prepayments on
securities purchased by the Fund at a premium also impose a risk of loss of
principal because the premium may not have been fully amortized at the time the
principal is prepaid in full.  The market for privately issued mortgage - and
asset-backed securities is smaller and less liquid than the market for
government-sponsored mortgage-backed securities.

     While many mortgage- and asset-backed securities are issued with only one
class of security, many are issued in more than one class, each with different
payment terms.  Multiple class mortgage- and asset-backed securities are issued
for two main reasons.   First, multiple classes may be used as a method of
providing credit support.  This is accomplished typically through creation of
one or more classes whose right to payments on the security is made subordinate
to the right to such payments of the remaining class or classes.  Second,
multiple classes may permit the issuance of securities with payment terms,

                                     - 20 -

<PAGE>   60

interest rates, or other characteristics differing both from those of each
other and from those of the underlying assets.  Examples include so-called
"strips" (mortgage - and asset-backed securities entitling the holder to
disproportionate interests with respect to the allocation of interest and
principal of the assets backing the security), and securities with class or
classes having characteristics which mimic the characteristics of non-mortgage-
or asset-backed securities, such as floating interest rates (i.e., interest
rates which adjust as a specified benchmark changes) or scheduled amortization
of principal.

     The Fund may invest in stripped mortgage- or asset-backed securities,
which receive differing proportions of the interest and principal payments from
the underlying assets.  The market value of such securities generally is more
sensitive to changes in prepayment and interest rates than is the case with
traditional mortgage- and asset-backed securities, and in some cases such
market value may be extremely volatile.  With respect to certain stripped
securities, such as interest only and principal only classes, a rate of
prepayment that is faster or slower than anticipated may result in the Fund
failing to recover all or a portion of its investment, even though the
securities are rated investment grade.

     Mortgage- and asset-backed securities backed by assets, other than as
described above, or in which the payment streams on the underlying assets are
allocated in a manner different than those described above may be issued in the
future.  The Fund may invest in such securities if such investment is otherwise
consistent with its investment objectives and policies and with the investment
restrictions of the Fund.

MORTGAGE DOLLAR ROLLS AND REVERSE REPURCHASE AGREEMENTS

     The Fund may engage in reverse repurchase agreements to facilitate
portfolio liquidity, a practice common in the mutual fund industry, or for
arbitrage transactions discussed below.  In a reverse repurchase agreement, the
Fund would sell a security and enter into an agreement to repurchase the
security at a specified future date and price.  The Fund generally retains the
right to interest and principal payments on the security.  Since the Fund
receives cash upon entering into a reverse repurchase agreement, it may be
considered a borrowing.  (See "Borrowing".)  When required by guidelines of the
SEC, the Fund will set aside permissible liquid assets in a segregated account
to secure its obligations to repurchase the security.

     The Fund may also enter into mortgage dollar rolls, in which the Fund
would sell mortgage-backed securities for delivery in the current month and
simultaneously contract to purchase substantially similar securities on a
specified future date.  While the Fund would forego principal and interest paid
on the mortgage-backed securities during the roll period, the Fund would be
compensated by the difference between the current sales price and the lower
price for the future purchase as well as by any interest earned on the proceeds
of the initial sale.  The Fund also could be compensated through the receipt of
fee income equivalent to a lower forward price.  At the time the Fund would
enter into a mortgage dollar roll, it would set aside permissible liquid assets
in a segregated account to secure its obligation for the forward commitment to
buy mortgage-backed securities.  Mortgage dollar roll transactions may be
considered a borrowing by the Fund.  (See "Borrowing".)

     The mortgage dollar rolls and reverse repurchase agreements entered into
by the Fund may be used as arbitrage transactions in which the Fund will
maintain an offsetting position in investment grade debt obligations or
repurchase agreements that mature on or before the settlement date on the
related mortgage dollar roll or reverse repurchase agreements.  Since the Fund
will receive interest on the securities or repurchase agreements in which it
invests the transaction proceeds, such transactions may involve leverage.
However, since such securities or repurchase agreements will be high quality
and will mature on or before the settlement date of the mortgage dollar roll or
reverse repurchase agreement, the Advisor believes that such arbitrage
transactions do not present the risks to the Fund that is associated with other
types of leverage.

MUNICIPAL OBLIGATIONS

     General obligation bonds are secured by the issuer's pledge of its full
faith, credit, and taxing power for the payment of interest and principal.
Revenue bonds are payable only from the revenues derived from a project or
facility or from the proceeds of a specified revenue source.  Industrial
development bonds are generally revenue bonds secured by payments from and the
credit of private users.  Municipal notes are issued to meet the short-term
funding requirements of state, regional, and local governments.  Municipal
notes include tax anticipation notes, bond anticipation notes, revenue
anticipation notes, tax and revenue anticipation notes, construction loan
notes, short-term discount notes, tax-exempt commercial paper, demand notes,
and similar instruments.  Municipal obligations include obligations, the
interest on which is exempt from federal income tax,

                                     - 21 -

<PAGE>   61

that may become available in the future as long as the Board of Directors of
the Fund determines that an investment in any such type of obligation is
consistent with the Fund's investment objective.

     Municipal lease obligations may take the form of a lease, an installment
purchase, or a conditional sales contract.  They are issued by state and local
governments and authorities to acquire land, equipment, and facilities, such as
state and municipal vehicles, telecommunications and computer equipment, and
other capital assets.  The Fund may purchase these obligations directly, or it
may purchase participation interests in such obligations.  Municipal leases are
generally subject to greater risks than general obligation or revenue bonds.
State constitutions and statutes set forth requirements that states or
municipalities must meet in order to issue municipal obligations.  Municipal
leases may contain a covenant by the state or municipality to budget for,
appropriate, and make payments due under the obligation.  Certain municipal
leases may, however, contain "non-appropriation" clauses which provide that the
issuer is not obligated to make payments on the obligation in future years
unless funds have been appropriated for this purpose each year.  Accordingly,
such obligations are subject to "non-appropriation" risk.  While municipal
leases are secured by the underlying capital asset, it may be difficult to
dispose of any such asset in the event of non-appropriation or other default.

REPURCHASE AGREEMENTS

     The Fund may enter into repurchase agreements with certain banks or
non-bank dealers.  In a repurchase agreement, the Fund buys a security at one
price, and at the time of sale, the seller agrees to repurchase the obligation
at a mutually agreed upon time and price (usually within seven days).  The
repurchase agreement, thereby, determines the yield during the purchaser's
holding period, while the seller's obligation to repurchase is secured by the
value of the underlying security.  The Advisor will monitor, on an ongoing
basis, the value of the underlying securities to ensure that the value always
equals or exceeds the repurchase price plus accrued interest.  Repurchase
agreements could involve certain risks in the event of a default or insolvency
of the other party to the agreement, including possible delays or restrictions
upon the Fund's ability to dispose of the underlying securities.  Although no
definitive creditworthiness criteria are used, the Advisor reviews the
creditworthiness of the banks and non-bank dealers with which the Fund enters
into repurchase agreements to evaluate those risks.  The Fund may, under
certain circumstances, deem repurchase agreements collateralized by U.S.
government securities to be investments in U.S. government securities.

SHORT SALES AGAINST THE BOX

     The Fund may sell securities short against the box to hedge unrealized
gains on portfolio securities.  Selling securities short against the box
involves selling a security that the Fund owns or has the right to acquire, for
delivery at a specified date in the future.  If the Fund sells securities short
against the box, it may protect unrealized gains, but will lose the opportunity
to profit on such securities if the price rises.

TEMPORARY DEFENSIVE POSITION

     When the Advisor determines that market conditions warrant a temporary
defensive position, the Fund may invest without limitation in cash and
short-term fixed income securities, including U.S. government securities,
commercial paper, banker's acceptances, certificates of deposit, and time
deposits.

VARIABLE- OR FLOATING-RATE SECURITIES

     The Fund may invest in securities which offer a variable- or floating-rate
of interest.  Variable-rate securities provide for automatic establishment of a
new interest rate at fixed intervals (e.g., daily, monthly, semi-annually,
etc.).  Floating-rate securities generally provide for automatic adjustment of
the interest rate whenever some specified interest rate index changes.  The
interest rate on variable- or floating-rate securities is ordinarily determined
by reference to or is a percentage of a bank's prime rate, the 90-day U.S.
Treasury bill rate, the rate of return on commercial paper or bank certificates
of deposit, an index of short-term interest rates, or some other objective
measure.

     Variable- or floating-rate securities frequently include a demand feature
entitling the holder to sell the securities to the issuer at par.  In many
cases, the demand feature can be exercised at any time on 7 days notice; in
other cases, the demand feature is exercisable at any time on 30 days notice or
on similar notice at intervals of not more than one year.  Some securities

                                     - 22 -

<PAGE>   62

which do not have variable or floating interest rates may be accompanied by
puts producing similar results and price characteristics.  When considering the
maturity of any instrument which may be sold or put to the issuer or a third
party, the Fund may consider that instrument's maturity to be shorter than its
stated maturity.

     Variable-rate demand notes include master demand notes which are
obligations that permit the Fund to invest fluctuating amounts, which may
change daily without penalty, pursuant to direct arrangements between the Fund,
as lender, and the borrower.  The interest rates on these notes fluctuate from
time to time.  The issuer of such obligations normally has a corresponding
right, after a given period, to prepay in its discretion the outstanding
principal amount of the obligations plus accrued interest upon a specified
number of days' notice to the holders of such obligations.  The interest rate
on a floating-rate demand obligation is based on a known lending rate, such as
a bank's prime rate, and is adjusted automatically each time such rate is
adjusted.  The interest rate on a variable-rate demand obligation is adjusted
automatically at specified intervals.  Frequently, such obligations are secured
by letters of credit or other credit support arrangements provided by banks.
Because these obligations are direct lending arrangements between the lender
and borrower, it is not contemplated that such instruments will generally be
traded.  There generally is not an established secondary market for these
obligations, although they are redeemable at face value.  Accordingly, where
these obligations are not secured by letters of credit or other credit support
arrangements, the Fund's right to redeem is dependent on the ability of the
borrower to pay principal and interest on demand.  Such obligations frequently
are not rated by credit rating agencies and, if not so rated, the Fund may
invest in them only if the Advisor  determines that at the time of investment
the obligations are of comparable quality to the other obligations in which the
Fund may invest.  The Advisor, on behalf of the Fund, will consider on an
ongoing basis the creditworthiness of the issuers of the floating- and
variable-rate demand obligations in the Fund's portfolio.

     The Fund will not invest more than 10% of its net assets in variable- and
floating-rate demand obligations that are not readily marketable (a variable-
or floating-rate demand obligation that may be disposed of on not more than
seven days notice will be deemed readily marketable and will not be subject to
this limitation).  (See "Illiquid Securities" and "Investment Restrictions.")
In addition, each variable- or floating-rate obligation must meet the credit
quality requirements applicable to all the Fund's investments at the time of
purchase.  When determining whether such an obligation meets the Fund's credit
quality requirements, the Fund may look to the credit quality of the financial
guarantor providing a letter of credit or other credit support arrangement.

     In determining the Fund's weighted average portfolio maturity, the Fund
will consider a floating or variable rate security to have a maturity equal to
its stated maturity (or redemption date if it has been called for redemption),
except that it may consider (i) variable rate securities to have a maturity
equal to the period remaining until the next readjustment in the interest rate,
unless subject to a demand feature, (ii) variable rate securities subject to a
demand feature to have a remaining maturity equal to the longer of (a) the next
readjustment in the interest rate or (b) the period remaining until the
principal can be recovered through demand, and (iii) floating rate securities
subject to a demand feature to have a maturity equal to the period remaining
until the principal can be recovered through demand.  Variable and floating
rate securities generally are subject to less principal fluctuation than
securities without these attributes since the securities usually trade at
amortized cost following the readjustment in the interest rate.

WARRANTS

     The Fund may acquire warrants.  Warrants are securities giving the holder
the right, but not the obligation, to buy the stock of an issuer at a given
price (generally higher than the value of the stock at the time of issuance)
during a specified period or perpetually.  Warrants may be acquired separately
or in connection with the acquisition of securities.  Warrants acquired by the
Fund in units or attached to securities are not subject to these restrictions.
Warrants do not carry with them the right to dividends or voting rights with
respect to the securities that they entitle their holder to purchase, and they
do not represent any rights in the assets of the issuer.  As a result, warrants
may be considered to have more speculative characteristics than certain other
types of investments.  In addition, the value of a warrant does not necessarily
change with the value of the underlying securities, and a warrant ceases to
have value if it is not exercised prior to its expiration date.

WHEN-ISSUED SECURITIES

     The Fund may from time to time purchase securities on a "when-issued"
basis.  The price of debt obligations purchased on a when-issued basis, which
may be expressed in yield terms, generally is fixed at the time the commitment
to

                                     - 23 -

<PAGE>   63

purchase is made, but delivery and payment for the securities take place at a
later date.  Normally, the settlement date occurs within 45 days of the
purchase although in some cases settlement may take longer.  During the period
between the purchase and settlement, no payment is made by the Fund to the
issuer and no interest on the debt obligations accrues to the Fund.  Forward
commitments involve a risk of loss if the value of the security to be purchased
declines prior to the settlement date, which risk is in addition to the risk of
decline in value of the Fund's other assets.  While when-issued securities may
be sold prior to the settlement date, the Fund intends to purchase such
securities with the purpose of actually acquiring them unless a sale appears
desirable for investment reasons.  At the time the Fund makes the commitment to
purchase a security on a when-issued basis, it will record the transaction and
reflect the value of the security in determining its net asset value.  The Fund
does not believe that their net asset values will be adversely affected by
purchases of securities on a when-issued basis.

     To the extent required by the SEC, the Fund will maintain cash and
marketable securities equal in value to commitments for when-issued securities.
Such segregated securities either will mature or, if necessary, be sold on or
before the settlement date.  When the time comes to pay for when-issued
securities, the Fund will meet its obligations from then-available cash flow,
sale of the securities held in the separate account, described above, sale of
other securities or, although it would not normally expect to do so, from the
sale of the when-issued securities themselves (which may have a market value
greater or less than the Fund's payment obligation).

ZERO-COUPON, STEP-COUPON AND PAY-IN-KIND SECURITIES

     The Fund may invest in zero-coupon, step-coupon, and pay-in-kind
securities.  These securities are debt securities that do not make regular cash
interest payments.  Zero-coupon and step-coupon securities are sold at a deep
discount to their face value.  Pay-in-kind securities pay interest through the
issuance of additional securities.  Because such securities do not pay current
cash income, the price of these securities can be volatile when interest rates
fluctuate.  While these securities do not pay current cash income, federal
income tax law requires the holders of zero-coupon, step-coupon, and
pay-in-kind securities to include in income each year the portion of the
original issue discount (or deemed discount) and other non-cash income on such
securities accruing that year.  In order to continue to qualify as a "regulated
investment company" under the Internal Revenue Code and avoid a certain excise
tax, the Fund may be required to distribute a portion of such discount and
income and may be required to dispose of other portfolio securities, which may
occur in periods of adverse market prices, in order to generate cash to meet
these distribution requirements.

                             PRINCIPAL SHAREHOLDERS

      As of ____________, 1997, no one owned of record and beneficially any
shares of the Fund.

                       INVESTMENT ADVISOR AND DISTRIBUTOR

     The Advisor to the Fund is Strong Capital Management, Inc.  Mr. Richard S.
Strong controls the Advisor.  Mr. Strong is the Chairman and a director of the
Advisor, Mr. Dragisic is the President and a director of the Advisor, Mr.
Totsky is a Senior Vice President of the Advisor, Mr. Lemke is a Senior Vice
President, Secretary and General Counsel of the Advisor, Mr. Flanagan is Senior
Vice President of the Advisor, Mr. Shenkenberg is Vice President, Assistant
Secretary, and Deputy General Counsel of the Advisor, and Mr. Weitzer is
Associate Counsel of the Advisor.  A brief description of the Fund's investment
advisory agreement ("Advisory Agreement") is set forth in the Prospectus under
"About the Fund - Management."

     The Advisory Agreement for the Fund is dated ____________, 1997, and will
remain in effect for a period of two years.  The Advisory Agreement was
approved by the Fund's initial shareholder on its first day of operations.  The
Advisory Agreement is required to be approved annually by either the Board of
Directors of the Fund or by vote of a majority of the Fund's outstanding voting
securities (as defined in the 1940 Act).  In either case, each annual renewal
must be approved by the vote of a majority of the Fund's directors who are not
parties to the Advisory Agreement or interested persons of any such party, cast
in person at a meeting called for the purpose of voting on such approval. Each
Advisory Agreement is terminable, without penalty, on 60 days' written notice
by the Board of Directors of the Fund, by vote of a majority of the Fund's
outstanding voting securities, or by the Advisor.  In addition, an Advisory
Agreement will terminate automatically in the event of its assignment.

     Under the terms of each Advisory Agreement, the Advisor manages the Fund's
investments subject to the supervision of the Fund's Board of Directors.  The
Advisor is responsible for investment decisions and supplies investment
research and portfolio management.  At its expense, the Advisor provides office
space and all necessary office facilities, equipment and personnel for
servicing the investments of the Fund.  The Advisor places all orders for the
purchase and sale of the Fund's portfolio securities at the Fund's expense.

     Except for expenses assumed by the Advisor, as set forth above, or by the
Distributor as described below with respect to the distribution of the Fund's
shares, the Fund is responsible for all its other expenses, including, without
limitation, interest

                                     - 27 -

<PAGE>   67

charges, taxes, brokerage commissions, and similar expenses; expenses of issue,
sale, repurchase, or redemption of shares; expenses of registering or
qualifying shares for sale; expenses for printing and distribution costs of
Prospectuses and quarterly financial statements mailed to existing
shareholders; and charges of custodians, transfer agents (including the
printing and mailing of reports and notices to shareholders), registrars,
auditing and legal services, clerical services related to recordkeeping and
shareholder relations, printing stock certificates; and fees for directors who
are not "interested persons" of the Advisor.

     As compensation for its services, the Fund pays to the Advisor a monthly
management fee at the annual rate of the average daily net asset value of the
Fund.  (See "Shareholder Manual - Determining Your Share Price" in the
Prospectus.)  From time to time, the Advisor may voluntarily waive all or a
portion of its management fee for the Fund.

     The Advisory Agreement requires the Advisor to reimburse the Fund in the
event that the expenses and charges payable by the Fund in any fiscal year,
including the management fee but excluding taxes, interest, brokerage
commissions, and similar fees and to the extent permitted extraordinary
expenses, exceed two percent (2%) of the average net asset value of the Fund
for such year, as determined by valuations made as of the close of each
business day of the year. Reimbursement of expenses in excess of the applicable
limitation will be made on a monthly basis and will be paid to the Fund by
reduction of the Advisor's fee, subject to later adjustment, month by month,
for the remainder of the Fund's fiscal year.  The Advisor may from time to time
voluntarily absorb expenses for the Fund in addition to the reimbursement of
expenses in excess of application limitations.

     On July 12, 1994, the Securities and Exchange Commission (the "SEC") filed
an administrative action (the "Order") against the Advisor, Mr. Strong, and
another employee of the Advisor in connection with conduct that occurred
between 1987 and early 1990. In re Strong/Corneliuson Capital Management, Inc.,
et al. Admin. Proc. File No. 3-8411. The proceeding was settled by consent
without admitting or denying the allegations in the Order. The Order found that
the Advisor and Mr. Strong aided and abetted violations of Section 17(a) of the
1940 Act by effecting trades between mutual funds, and between mutual funds and
Harbour Investments Ltd. ("Harbour"), without complying with the exemptive
provisions of SEC Rule 17a-7 or otherwise obtaining an exemption. It further
found that the Advisor violated, and Mr. Strong aided and abetted violations
of, the disclosure provisions of the 1940 Act and the Investment Advisers Act
of 1940 by misrepresenting the Advisor's policy on personal trading and by
failing to disclose trading by Harbour, an entity in which principals of the
Advisor owned between 18 and 25 percent of the voting stock. As part of the
settlement, the respondents agreed to a censure and a cease and desist order
and the Advisor agreed to various undertakings, including adoption of certain
procedures and a limitation for six months on accepting certain types of new
advisory clients.

     On June 6, 1996, the Department of Labor (the "DOL") filed an action
against the Advisor for equitable relief alleging violations of the Employee
Retirement Income Security Act of 1974 ("ERISA") in connection with cross
trades that occurred between 1987 and late 1989 involving certain pension
accounts managed by the Advisor.  Contemporaneous with this filing, the
Advisor, without admitting or denying the DOL's allegations, agreed to the
entry of a consent judgment resolving all matters relating to the allegations.
Reich v. Strong Capital Management, Inc., (U.S.D.C. E.D. WI) (the "Consent
Judgment").  Under the terms of the Consent Judgment, the Advisor agreed to
reimburse the affected accounts a total of $5.9 million.  The settlement did
not have any material impact on the Advisor's financial position or operations.

     The Fund and the Advisor have adopted a Code of Ethics (the "Code") which
governs the personal trading activities of all "Access Persons" of the Advisor.
Access Persons include every director and officer of the Advisor and the
investment companies managed by the Advisor, including the Fund, as well as
certain employees of the Advisor who have access to information relating to the
purchase or sale of securities by the Advisor on behalf of accounts managed by
it.  The Code is based upon the principal that such Access Persons have a
fiduciary duty to place the interests of the Fund and the Advisor's other
clients ahead of their own.

     The Code requires Access Persons (other than Access Persons who are
independent directors of the investment companies managed by the Advisor,
including the Fund) to, among other things, preclear their securities
transactions (with limited exceptions, such as transactions in shares of mutual
funds, direct obligations of the U.S. government, and certain options on
broad-based securities market indexes) and to execute such transactions through
the Advisor's trading department. The Code, which applies to all Access Persons
(other than Access Persons who are independent directors of the investment
companies managed by the Advisor, including the Fund), includes a ban on
acquiring any securities in an initial public offering, other than a new
offering of a registered open-end investment company, and a prohibition from
profiting on short-term trading

                                     - 28 -

<PAGE>   68

in securities.  In addition, no Access Person may purchase or sell any security
which is contemporaneously being purchased or sold, or to the knowledge of the
Access Person, is being considered for purchase or sale, by the Advisor on
behalf of any mutual fund or other account managed by it.  Finally, the Code
provides for trading "black out" periods of seven calendar days during which
time Access Persons who are portfolio managers may not trade in securities
which have been purchased or sold  by any mutual fund or other account managed
by the portfolio manager.

     From time to time the Advisor votes the shares owned by the Fund according
to its Statement of General Proxy Voting Policy ("Proxy Voting Policy").  The
general principal of the Proxy Voting Policy is to vote any beneficial interest
in an equity security prudently and solely in the best long-term economic
interest of the Fund and its beneficiaries considering all relevant factors and
without undue influence from individuals or groups who may have an economic
interest in the outcome of a proxy vote.  Shareholders may obtain a copy of the
Proxy Voting Policy upon request from the Advisor.

     The Advisor provides investment advisory services for multiple clients and
may give advice and take action, with respect to any client, that may differ
from the advice given, or the timing or nature of action taken, with respect to
any one account.  However, the Advisor will allocate over a period of time, to
the extent practical, investment opportunities to each account on a fair and
equitable basis relative to other similarly-situated client accounts.  The
Advisor, its principals and associates (to the extent not prohibited by the
Code), and other clients of the Advisor may have, acquire, increase, decrease,
or dispose of securities or interests therein for an account that are or may be
deemed to be inconsistent with the actions taken by such persons.

     Under a Distribution Agreement with the Fund dated ____________, 1997,
Strong Funds Distributors, Inc. ("Distributor"), a subsidiary of the Advisor,
acts as underwriter of the Fund's shares.  The Distribution Agreement provides
that the Distributor will use its best efforts to distribute the Fund's shares.
Since the Fund is a "no-load" fund, no sales commissions are charged on the
purchase of Fund shares.  Each Distribution Agreement further provides that the
Distributor will bear the additional costs of printing Prospectuses and
shareholder reports which are used for selling purposes, as well as advertising
and any other costs attributable to the distribution of the Fund's shares.  The
Distributor is an indirect subsidiary of the Advisor and controlled by the
Advisor and Richard S. Strong.  The Distribution Agreement is subject to the
same termination and renewal provisions as are described above with respect to
the Advisory Agreement.

     From time to time, the Distributor may hold in-house sales incentive
programs for its associated persons under which these persons may receive
non-cash compensation awards in connection with the sale and distribution of
the Fund's shares.  These awards may include items such as, but not limited to,
gifts, merchandise, gift certificates, and payment of travel expenses, meals
and lodging.  As required by the National Association of Securities Dealers,
Inc. or NASD's proposed rule amendments in this area, any in-house sales
incentive program will be multi-product oriented, i.e., any incentive will be
based on an associated person's gross production of all securities within a
product type and will not be based on the sales of shares of any specifically
designated mutual fund.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

     The Advisor is responsible for decisions to buy and sell securities for
the Fund and for the placement of the Fund's portfolio business and the
negotiation of the commissions to be paid on such transactions.  It is the
policy of the Advisor to seek the best execution at the best security price
available with respect to each transaction, in light of the overall quality of
brokerage and research services provided to the Advisor or the Fund. In
over-the-counter transactions, orders are placed directly with a principal
market maker unless it is believed that a better price and execution can be
obtained using a broker.  The best price to the Fund means the best net price
without regard to the mix between purchase or sale price and commissions, if
any.  In selecting broker-dealers and in negotiating commissions, the Advisor
considers a variety of factors, including best price and execution, the full
range of brokerage services provided by the broker, as well as its capital
strength and stability, and the quality of the research and research services
provided by the broker.  Brokerage will not be allocated based on the sale of
any shares of the Strong Funds.

     The Advisor has adopted procedures that provide generally for the Advisor
to seek to bunch orders for the purchase or sale of the same security for the
Fund, other mutual funds managed by the Advisor, and other advisory clients
(collectively, the "client accounts").  The Advisor will bunch orders when it
deems it to be appropriate and in the best interests of the client accounts.
When a bunched order is filled in its entirety, each participating client
account will participate at the average share

                                     - 29 -

<PAGE>   69

price for the bunched order on the same business day, and transaction costs
shall be shared pro rata based on each client's participation in the bunched
order.  When a bunched order is only partially filled, the securities purchased
will be allocated on a pro rata basis to each client account participating in
the bunched order based upon the initial amount requested for the account,
subject to certain exceptions, and each participating account will participate
at the average share price for the bunched order on the same business day.

     Section 28(e) of the Securities Exchange Act of 1934 ("Section 28(e)")
permits an investment advisor, under certain circumstances, to cause an account
to pay a broker or dealer a commission for effecting a transaction in excess of
the amount of commission another broker or dealer would have charged for
effecting the transaction in recognition of the value of the brokerage and
research services provided by the broker or dealer.  Brokerage and research
services include (a) furnishing advice 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; (b)
furnishing analyses and reports concerning issuers, industries, securities,
economic factors and trends, portfolio strategy, and the performance of
accounts; and (c) effecting securities transactions and performing functions
incidental thereto (such as clearance, settlement, and custody).

     In carrying out the provisions of the Advisory Agreement, the Advisor may
cause the Fund to pay a broker, which provides brokerage and research services
to the Advisor, a commission for effecting a securities transaction in excess
of the amount another broker would have charged for effecting the transaction.
The Advisor believes it is important to its investment decision-making process
to have access to independent research.  The Advisory Agreement provides that
such higher commissions will not be paid by the Fund unless (a) the Advisor
determines in good faith that the amount is reasonable in relation to the
services in terms of the particular transaction or in terms of the Advisor's
overall responsibilities with respect to the accounts as to which it exercises
investment discretion; (b) such payment is made in compliance with the
provisions of Section 28(e), other applicable state and federal laws, and the
Advisory Agreement; and (c) in the opinion of the Advisor, the total
commissions paid by the Fund will be reasonable in relation to the benefits to
the Fund over the long term.  The investment management fees paid by the Fund
under the Advisory Agreement is not reduced as a result of the Advisor's
receipt of research services.

     Generally, research services provided by brokers may include information
on the economy, industries, groups of securities, individual companies,
statistical information, accounting and tax law interpretations, political
developments, legal developments affecting portfolio securities, technical
market action, pricing and appraisal services, credit analysis, risk
measurement analysis, performance analysis, and analysis of corporate
responsibility issues. Such research services are received primarily in the
form of written reports, telephone contacts, and personal meetings with
security analysts. In addition, such research services may be provided in the
form of access to various computer-generated data, computer hardware and
software, and meetings arranged with corporate and industry spokespersons,
economists, academicians, and government representatives. In some cases,
research services are generated by third parties but are provided to the
Advisor by or through brokers. Such brokers may pay for all or a portion of
computer hardware and software costs relating to the pricing of securities.

     Where the Advisor itself receives both administrative benefits and
research and brokerage services from the services provided by brokers, it makes
a good faith allocation between the administrative benefits and the research
and brokerage services, and will pay for any administrative benefits with cash.
In making good faith allocations of costs between administrative benefits and
research and brokerage services, a conflict of interest may exist by reason of
the Advisor's allocation of the costs of such benefits and services between
those that primarily benefit the Advisor and those that primarily benefit the
Fund and other advisory clients.

     From time to time, the Advisor may purchase new issues of securities for
the Fund in a fixed price offering. In these situations, the seller may be a
member of the selling group that will, in addition to selling the securities to
the Fund and other advisory clients, provide the Advisor with research. The
National Association of Securities Dealers has adopted rules expressly
permitting these types of arrangements under certain circumstances. Generally,
the seller will provide research "credits" in these situations at a rate that
is higher than that which is available for typical secondary market
transactions. These arrangements may not fall within the safe harbor of Section
28(e).

     Each year, the Advisor considers the amount and nature of research and
research services provided by brokers, as well as the extent to which such
services are relied upon, and attempts to allocate a portion of the brokerage
business of the Fund and other advisory clients on the basis of that
consideration. In addition, brokers may suggest a level of business they

                                     - 30 -

<PAGE>   70

would like to receive in order to continue to provide such services. The actual
brokerage business received by a broker may be more or less than the suggested
allocations, depending upon the Advisor's evaluation of all applicable
considerations.

     The Advisor has informal arrangements with various brokers whereby, in
consideration for providing research services and subject to Section 28(e), the
Advisor allocates brokerage to those firms, provided that their brokerage and
research services were satisfactory to the Advisor and their execution
capabilities were compatible with the Advisor's policy of seeking best
execution at the best security price available, as discussed above.  In no case
will the Advisor make binding commitments as to the level of brokerage
commissions it will allocate to a broker, nor will it commit to pay cash if any
informal targets are not met.  The Advisor anticipates it will continue to
enter into such brokerage arrangements.

     The Advisor may direct the purchase of securities on behalf of the Fund
and other advisory clients in secondary market transactions, in public
offerings directly from an underwriter, or in privately negotiated transactions
with an issuer. When the Advisor believes the circumstances so warrant,
securities purchased in public offerings may be resold shortly after
acquisition in the immediate aftermarket for the security in order to take
advantage of price appreciation from the public offering price or for other
reasons. Short-term trading of securities acquired in public offerings, or
otherwise, may result in higher portfolio turnover and associated brokerage
expenses.

     The Advisor places portfolio transactions for other advisory accounts,
including other mutual funds managed by the Advisor.  Research services
furnished by firms through which the Fund effects its securities transactions
may be used by the Advisor in servicing all of its accounts; not all of such
services may be used by the Advisor in connection with the Fund.  In the
opinion of the Advisor, it is not possible to measure separately the benefits
from research services to each of the accounts (including the Fund) managed by
the Advisor. Because the volume and nature of the trading activities of the
accounts are not uniform, the amount of commissions in excess of those charged
by another broker paid by each account for brokerage and research services will
vary.  However, in the opinion of the Advisor, such costs to the Fund will not
be disproportionate to the benefits received by the Fund on a continuing basis.

     The Advisor seeks to allocate portfolio transactions equitably whenever
concurrent decisions are made to purchase or sell securities by the Fund and
another advisory account. In some cases, this procedure could have an adverse
effect on the price or the amount of securities available to the Fund.  In
making such allocations between the Fund and other advisory accounts, the main
factors considered by the Advisor are the respective investment objectives, the
relative size of portfolio holdings of the same or comparable securities, the
availability of cash for investment, the size of investment commitments
generally held, and the opinions of the persons responsible for recommending
the investment.

     Where consistent with a client's investment objectives, investment
restrictions, and risk tolerance, the Advisor may purchase securities sold in
underwritten public offerings for client accounts, commonly referred to as
"deal" securities.  The Advisor has adopted deal allocation procedures (the
"procedures"), summarized below, that reflect the Advisor's overriding policy
that deal securities must be allocated among participating client accounts in a
fair and equitable manner and that deal securities may not be allocated in a
manner that unfairly discriminates in favor of certain clients or types of
clients.

     The procedures provide that, in determining which client accounts a
portfolio manager team will seek to have purchase deal securities, the team
will consider all relevant factors including, but not limited to, the nature,
size, and expected allocation to the Advisor of deal securities; the size of
the account(s); the accounts' investment objectives and restrictions; the risk
tolerance of the client; the client's tolerance for possibly higher portfolio
turnover; the amount of commissions generated by the account during the past
year; and the number of other deals the client has participated in during the
past year.

     Where more than one of the Advisor portfolio manager team seeks to have
client accounts participate in a deal and the amount of deal securities
allocated to the Advisor by the underwriting syndicate is less than the
aggregate amount ordered by the Advisor (a "reduced allocation"), the deal
securities will be allocated among the portfolio manager teams based on all
relevant factors.  The primary factor shall be assets under management,
although other factors that may be considered in the allocation decision
include, but are not limited to, the nature, size, and expected Advisor
allocation of the deal; the amount of brokerage commissions or other amounts
generated by the respective participating portfolio manager teams; and which
portfolio manager team is primarily responsible for the Advisor receiving
securities in the deal.  Based on the relevant factors, the Advisor has
established general allocation percentages for its portfolio manager teams, and
these percentages are reviewed

                                     - 31 -

<PAGE>   71

on a regular basis to determine whether asset growth or other factors make it
appropriate to use different general allocation percentages for reduced
allocations.

     When a portfolio manager team receives a reduced allocation of deal
securities, the portfolio manager team will allocate the reduced allocation
among client accounts in accordance with the allocation percentages set forth
in the team's initial allocation instructions for the deal securities, except
where this would result in a de minimis allocation to any client account.  On a
regular basis, the Advisor reviews the allocation of deal securities to ensure
that they have been allocated in a fair and equitable manner that does not
unfairly discriminate in favor of certain clients or types of clients.

                                   CUSTODIAN

     As custodian of the Fund's assets, Firstar Trust Company, P.O. Box 701,
Milwaukee, Wisconsin 53201, has custody of all securities and cash of the Fund,
delivers and receives payment for securities sold, receives and pays for
securities purchased, collects income from investments, and performs other
duties, all as directed by the officers of the Fund.  The custodian and, if
applicable, the sub-custodian are in no way responsible for any of the
investment policies or decisions of the Fund.

                  TRANSFER AGENT AND DIVIDEND-DISBURSING AGENT

     The Advisor acts as transfer agent and dividend-disbursing agent for the
Fund.  The Advisor is compensated based on an annual fee per open account of
$31.50, plus out-of-pocket expenses, such as postage and printing expenses in
connection with shareholder communications. The Advisor also receives an annual
fee per closed account of $4.20 from the Fund. The fees received and the
services provided as transfer agent and dividend disbursing agent are in
addition to those received and provided by the Advisor under the Advisory
Agreement.  In addition, the Advisor provides certain printing and mailing
services for the Fund, such as printing and mailing of shareholder account
statements, checks, and tax forms.

     From time to time, the Fund, directly or indirectly through arrangements
with the Advisor, and/or the Advisor may pay amounts to third parties that
provide transfer agent and other administrative services relating to the Fund
to persons who beneficially own interests in the Fund, such as participants in
401(k) plans.  These services may include, among other things, sub-accounting
services, transfer agent type activities, answering inquiries relating to the
Fund, transmitting, on behalf of the Fund, proxy statements, annual reports,
updated Prospectuses, other communications regarding the Fund, and related
services as the Fund or beneficial owners may reasonably request.  In such
cases, the Fund will not pay fees based on the number of beneficial owners at a
rate that is greater than the rate the Fund is currently paying the Advisor for
providing these services to Fund shareholders.

                                     TAXES

GENERAL

     As indicated under "About the Fund - Distributions and Taxes" in the
Prospectus, the Fund intends to continue to qualify annually for treatment as a
regulated investment company ("RIC") under the Internal Revenue Code of 1986,
as amended (the "Code").  This qualification does not involve government
supervision of the Fund's management practices or policies.

     In order to qualify for treatment as a RIC under the Code, the Fund must
distribute to its shareholders for each taxable year at least 90% of its
investment company taxable income (consisting generally of net investment
income, net short-term capital gain, and net gains from certain foreign
currency transactions ) ("Distribution Requirement") and must meet several
additional requirements.  For the Fund these requirements include the
following: (1) the Fund must derive at least 90% of its gross income each
taxable year from dividends, interest, payments with respect to securities
loans, and gains from the sale or other disposition of securities or foreign
currencies or other income (including gains from options, futures, or forward
currency contracts) derived with respect to its business of investing in
securities or these currencies ("Income Requirement"); (2) the Fund must derive
less than 30% of its gross income each taxable year from the sale or other
disposition of securities, or options or futures (other than those on foreign
currencies), or foreign currencies (or options, futures, or forward contracts
thereon) that are not directly related to the Fund's principal business of
investing in securities (or options and futures with respect to

                                     - 32 -

<PAGE>   72

securities) that were held for less than three months ("30% Limitation"); (3)
at the close of each quarter of the Fund's taxable year, at least 50% of the
value of its total assets must be represented by cash and cash items, U.S.
government securities, securities of other RICs, and other securities, with
these other securities limited, in respect of any one issuer, to an amount that
does not exceed 5% of the value of the Fund's total assets and that does not
represent more than 10% of the issuer's outstanding voting securities; and (4)
at the close of each quarter of the Fund's taxable year, not more than 25% of
the value of its total assets may be invested in securities (other than U.S.
government securities or the securities of other RICs) of any one issuer.  From
time to time the Advisor may find it necessary to make certain types of
investments for the purpose of ensuring that the Fund continues to qualify for
treatment as a RIC under the Code.

     If Fund shares are sold at a loss after being held for six months or less,
the loss will be treated as long-term, instead of short-term, capital loss to
the extent of any capital gain distributions received on those shares.

     The Fund will be subject to a nondeductible 4% excise tax ("Excise Tax")
to the extent it fails to distribute by the end of any calendar year
substantially all of its ordinary income for that year and capital gain net
income for the one-year period ending on October 31 of that year, plus certain
other amounts.

FOREIGN TRANSACTIONS

     Interest and dividends received by the Fund may be subject to income,
withholding, or other taxes imposed by foreign countries and U.S. possessions
that would reduce the yield on its securities.  Tax conventions between certain
countries and the United States may reduce or eliminate these foreign taxes,
however, and many foreign countries do not impose taxes on capital gains in
respect of investments by foreign investors.

     The Fund maintains its accounts and calculates its income in U.S. dollars.
In general, gain or loss (1) from the disposition of foreign currencies and
forward currency contracts, (2) from the disposition of
foreign-currency-denominated debt securities that are attributable to
fluctuations in exchange rates between the date the securities are acquired and
their disposition date, and (3) attributable to fluctuations in exchange rates
between the time the Fund accrues interest or other receivables or expenses or
other liabilities denominated in a foreign currency and the time the Fund
actually collects those receivables or pays those liabilities, will be treated
as ordinary income or loss.  A foreign-currency-denominated debt security
acquired by the Fund may bear interest at a high normal rate that takes into
account expected decreases in the value of the principal amount of the security
due to anticipated currency devaluations; in that case, the Fund would be
required to include the interest in income as it accrues but generally would
realize a currency loss with respect to the principal only when the principal
was received (through disposition or upon maturity).

DERIVATIVE INSTRUMENTS

     The use of derivatives strategies, such as purchasing and selling
(writing) options and futures and entering into forward currency contracts,
involves complex rules that will determine for income tax purposes the
character and timing of recognition of the gains and losses the Fund realizes
in connection therewith.  Gains from the disposition of foreign currencies
(except certain gains therefrom that may be executed by future regulations),
and income from transactions in options, futures, and forward currency
contracts derived by the Fund with respect to its business of investing in
securities or foreign currencies, will qualify as permissible income under the
Income Requirement.  However, income from the disposition of options and
futures (other than those on foreign currencies) will be subject to the 30%
Limitation if they are held for less than three months.  Income from the
disposition of foreign currencies, and options, futures, and forward contracts
on foreign currencies that are not directly related to the Fund's principal
business of investing in securities (or options and futures with respect to
securities) also will be subject to the 30% Limitation if they are held for
less than three months.

     If the Fund satisfies certain requirements, any increase in value of a
position that is part of a "designated hedge" will be offset by any decrease in
value (whether realized or not) of the offsetting hedging position during the
period of the hedge for purposes of determining whether the Fund satisfies the
30% Limitation.  Thus, only the net gain (if any) from the designated hedge
will be included in gross income for purposes of that limitation.  The Fund
intends that, when they engage in hedging strategies, the hedging transactions
will qualify for this treatment, but at the present time it is not clear
whether this treatment will be available for all of the Fund's hedging
transactions.  To the extent this treatment is not available or is not elected
by the

                                     - 33 -

<PAGE>   73

Fund, it may be forced to defer the closing out of certain options, futures, or
forward currency contracts beyond the time when it otherwise would be
advantageous to do so, in order for the Fund to continue to qualify as a RIC.

     For federal income tax purposes, the Fund is required to recognize as
income for each taxable year its net unrealized gains and losses on options,
futures, or forward currency contracts that are subject to section 1256 of the
Code ("Section 1256 Contracts") and are held by the Fund as of the end of the
year, as well as gains and losses on Section 1256 Contracts actually realized
during the year.  Except for Section 1256 Contracts that are part of a "mixed
straddle" and with respect to which the Fund makes a certain election, any gain
or loss recognized with respect to Section 1256 Contracts is considered to be
60% long-term capital gain or loss and 40% short-term capital gain or loss,
without regard to the holding period of the Section 1256 Contract.  Unrealized
gains on Section 1256 Contracts that have been held by the Fund for less than
three months as of the end of its taxable year, and that are recognized for
federal income tax purposes as described above, will not be considered gains on
investments held for less than three months for purposes of the 30% Limitation.

ZERO-COUPON, STEP-COUPON, AND PAY-IN-KIND SECURITIES

     The Fund may acquire zero-coupon, step-coupon, or other securities issued
with original issue discount.  As a holder of those securities, the Fund must
include in its income the original issue discount that accrues on the
securities during the taxable year, even if the Fund receives no corresponding
payment on the securities during the year.  Similarly, the Fund must include in
its income securities it receives as "interest" on pay-in-kind securities.
Because the Fund annually must distribute substantially all of its investment
company taxable income, including any original issue discount and other
non-cash income, to satisfy the Distribution Requirement and avoid imposition
of the Excise Tax, it may be required in a particular year to distribute as a
dividend an amount that is greater than the total amount of cash it actually
receives.  Those distributions may be made from the proceeds on sales of
portfolio securities, if necessary.  The Fund may realize capital gains or
losses from those sales, which would increase or decrease its investment
company taxable income or net capital gain, or both.  In addition, any such
gains may be realized on the disposition of securities held for less than three
months.  Because of the 30% Limitation, any such gains would reduce the Fund's
ability to sell other securities, or certain options, or futures, or forward
currency  contracts, held for less that three months that it might wish to sell
in the ordinary course of its portfolio management.

     The foregoing federal tax discussion as well as the tax discussion
contained within the Prospectus under "About the Fund - Distributions and
Taxes" is intended to provide you with an overview of the impact of federal
income tax provisions on the Fund or its shareholders.  These tax provisions
are subject to change by legislative or administrative action at the federal,
state, or local level, and any changes may be applied retroactively.  Any such
action that limits or restricts the Fund's current ability to pass-through
earnings without taxation at the Fund level, or otherwise materially changes
the Fund's tax treatment, could adversely affect the value of a shareholder's
investment in the Fund.  Because the Fund's taxes are a complex matter, you
should consult your tax adviser for more detailed information concerning the
taxation of the Fund and the federal, state, and local tax consequences to
shareholders of an investment in the Fund.

                        DETERMINATION OF NET ASSET VALUE

     As set forth in the Prospectus under the caption "Shareholder Manual -
Determining Your Share Price," the net asset value of the Fund will be
determined as of the close of trading on each day the New York Stock Exchange
(the "NYSE") is open for trading. The New York Stock Exchange is open for
trading Monday through Friday except New Year's Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and
Christmas Day.  Additionally, if any of the aforementioned holidays falls on a
Saturday, the NYSE will not be open for trading on the preceding Friday, and
when any such holiday falls on a Sunday, the NYSE will not be open for trading
on the succeeding Monday, unless unusual business conditions exist, such as the
ending of a monthly or yearly accounting period.

                       ADDITIONAL SHAREHOLDER INFORMATION

TELEPHONE EXCHANGE AND REDEMPTION PRIVILEGES

     The Fund employs reasonable procedures to confirm that instructions
communicated by telephone are genuine. The Fund may not be liable for losses
due to unauthorized or fraudulent instructions. Such procedures include but are
not limited to

                                     - 34 -

<PAGE>   74

requiring a form of personal identification prior to acting on instructions
received by telephone, providing written confirmations of such transactions to
the address of record, and tape recording telephone instructions.

REDEMPTION-IN-KIND

     The Fund has elected to be governed by Rule 18f-1 under the 1940 Act,
which obligates the Fund to redeem shares in cash, with respect to any one
shareholder during any 90-day period, up to the lesser of $250,000 or 1% of the
assets of the Fund.  If the Advisor determines that existing conditions make
cash payments undesirable, redemption payments may be made in whole or in part
in securities or other financial assets, valued for this purpose as they are
valued in computing the NAV for the Fund's shares (a "redemption-in-kind").
Shareholders receiving securities or other financial assets in a
redemption-in-kind may realize a gain or loss for tax purposes, and will incur
any costs of sale, as well as the associated inconveniences.  If you expect to
make a redemption in excess of the lesser of $250,000 or 1% of the Fund's
assets during any 90-day period and would like to avoid any possibility of
being paid with securities in-kind, you may do so by providing Strong Funds
with an unconditional instruction to redeem at least 15 calendar days prior to
the date on which the redemption transaction is to occur, specifying the dollar
amount or number of shares to be redeemed and the date of the transaction
(please call 1-800-368-3863).  This will provide the Fund with sufficient time
to raise the cash in an orderly manner to pay the redemption and thereby
minimize the effect of the redemption on the interests of the Fund's remaining
shareholders.  Redemption checks in excess of the lesser of $250,000 or 1% of
the Fund's assets during any 90-day period may not be honored by the Fund if
the Advisor determines that existing conditions make cash payments undesirable.

RETIREMENT PLANS

Individual Retirement Account (IRA): Everyone under age 70 1/2 with earned
income may contribute to a tax-deferred IRA. The Strong Funds offer a prototype
plan for you to establish your own IRA. You are allowed to contribute up to the
lesser of $2,000 or 100% of your earned income each year to your IRA (or up to
$4,000 between your IRA and your non-working spouses' IRA).  Under certain
circumstances, your contribution will be deductible.

Direct Rollover IRA: To avoid the mandatory 20% federal withholding tax on
distributions,  you must transfer the qualified retirement or Code section
403(b) plan distribution directly into an IRA. The distribution must be
eligible for rollover.  The amount of your Direct Rollover IRA contribution
will not be included in your taxable income for the year.

Simplified Employee Pension Plan (SEP-IRA): A SEP-IRA plan allows an employer
to make deductible contributions to separate IRA accounts established for each
eligible employee.

Salary Reduction Simplified Employee Pension Plan (SAR SEP-IRA): A SAR SEP-IRA
plan is a type of SEP-IRA plan in which an employer may allow employees to
defer part of their salaries and contribute to an IRA account. These deferrals
help lower the employees' taxable income.   Please note that you may no longer
open new SAR SEP-IRA plans (since December 31, 1996).  However, employers with
SAR SEP-IRA plans that were established prior to January 31, 1997 may still
open accounts for new employees.

Simplified Incentive Match Plan for Employees (SIMPLE-IRA):  A SIMPLE-IRA plan
is a retirement savings plan that allows employees to contribute a percentage
of their compensation, up to $6,000, on a pre-tax basis, to a SIMPLE-IRA
account.  The employer is required to make annual contributions to eligible
employees' accounts.  All contributions grow tax-deferred.

Defined Contribution Plan: A defined contribution plan allows self-employed
individuals, partners, or a corporation to provide retirement benefits for
themselves and their employees.  Plan types include: profit-sharing plans,
money purchase pension plans, and paired plans (a combination of a
profit-sharing plan and a money purchase plan).

401(k) Plan: A 401(k) plan is a type of profit-sharing plan that allows
employees to have part of their salary contributed on a pre-tax basis to a
retirement plan which will earn tax-deferred income. A 401(k) plan is funded by
employee contributions, employer contributions, or a combination of both.

403(b)(7) Plan: A tax-sheltered custodial account designed to qualify under
section 403(b)(7) of the Code is available for use by employees of certain
educational, non-profit, hospital, and charitable organizations.

</TABLE>

(1) Prior to April 17, 1995, the Fund's name was Strong U.S. Treasury
    Money Fund, Inc.

     The Fund is a series of common stock of Strong Income Funds, Inc., a
Wisconsin corporation (a "Corporation") that is authorized to offer separate
series of shares representing interests in separate portfolios of securities,
each with differing objectives.  The shares in any one portfolio may, in turn,
be offered in separate classes, each with differing preferences, limitations or
relative rights.  However, the Articles of Incorporation for the Corporation
provides that if additional classes of shares are issued by the Corporation,
such new classes of shares may not affect the preferences, limitations or
relative rights of the Corporation's outstanding shares.  In addition, the
Board of Directors of the Corporation is authorized to allocate assets,
liabilities, income and expenses to each series and class.  Classes within a
series may have different expense arrangements than other classes of the same
series and, accordingly, the net asset value of shares within a series may
differ.  Finally, all holders of shares of the Corporation may vote on each
matter presented to shareholders for action except with respect to any matter
which affects only one or more series or class, in which case only the shares
of the affected series or class are entitled to vote. Fractional shares have
the same rights proportionately as do full shares. Shares of the Corporation
have no preemptive, conversion, or subscription rights.  If the Corporation
issues additional series, the assets belonging to each series of shares will be
held separately by the custodian, and in effect each series will be a separate
fund.

                              SHAREHOLDER MEETINGS

     The Wisconsin Business Corporation Law permits registered investment
companies, such as the Corporation, to operate without an annual meeting of
shareholders under specified circumstances if an annual meeting is not required
by the 1940 Act.  The Corporation has adopted the appropriate provisions in
their Bylaws and may, at their discretion, not hold an annual meeting in any
year in which the election of directors is not required to be acted on by
shareholders under the 1940 Act.

     The Corporation's Bylaws allow for a director to be removed by its
shareholders with or without cause, only at a  meeting called for the purpose
of removing the director. Upon the written request of the holders of shares
entitled to not less than ten percent (10%) of all the votes entitled to be
cast at such meeting, the Secretary of the Corporation shall promptly call a
special meeting of shareholders for the purpose of voting upon the question of
removal of any director. The Secretary of the Corporation shall inform such
shareholders of the reasonable estimated costs of preparing and mailing the
notice of the meeting, and upon payment to the Corporation of such costs, the
Corporation shall give not less than ten nor more than sixty days notice of the
special meeting.

                            PERFORMANCE INFORMATION

     As described in the "About the Fund - Performance Information" section of
the Fund's Prospectus, the Fund's historical performance or return may be shown
in the form of "yield."  In addition, the Funds' performance may be shown in
the form of "average annual total return," "total return," and "cumulative
total return."  From time to time, the advisor agrees to waive or reduce its
management fee and to absorb certain operating expenses for the Fund.

YIELD

     The Fund's yield is computed in accordance with a standardized method
prescribed by rules of the SEC.  Under that method, the current yield quotation
for the Fund is based on a one month or 30-day period.  The yield is computed
by dividing

                                     - 36 -

<PAGE>   76

the net investment income per share earned during the 30-day or one month
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.
            d =  the maximum offering price per share on the last day of the
                 period.

DISTRIBUTION RATE

     The distribution rate is computed, according to a non-standardized
formula, by dividing the total amount of actual distributions per share paid by
the Fund over a twelve month period by the Fund's net asset value on the last
day of the period.  The distribution rate differs from the Fund's yield because
the distribution rate includes distributions to shareholders from sources other
than dividends and interest, such as premium income from option writing and
short-term capital gains.  Therefore, the Fund's distribution rate may be
substantially different than its yield.  Both the Fund's yield and distribution
rate will fluctuate.

AVERAGE ANNUAL TOTAL RETURN

     The average annual total return of the Fund is computed by finding the
average annual compounded rates of return over these periods that would equate
the initial amount invested to the ending redeemable value, according to the
following formula:
                                 n
                        P (1 + T) = ERV


                P =  a hypothetical initial payment of $10,000.
                T =  average annual total return.
                n 
                  =  number of years.
              ERV =  ending redeemable value of a hypothetical $10,000 payment
                     made at the beginning of the stated periods at the end of 
                     the stated periods.

TOTAL RETURN

     Calculation of the Fund's total return is not subject to a standardized
formula.  Total return performance for a specific period is calculated by first
taking an investment (assumed below to be $10,000) ("initial investment") in
the Fund's shares on the first day of the period and computing the "ending
value" of that investment at the end of the period.  The total return
percentage is then determined by subtracting the initial investment from the
ending value and dividing the remainder by the initial investment and
expressing the result as a percentage.  The calculation assumes that all income
and capital gains dividends paid by the Fund have been reinvested at net asset
value on the reinvestment dates during the period.  Total return may also be
shown as the increased dollar value of the hypothetical investment over the
period.  Total return figures for various periods are set forth in the table
below.

CUMULATIVE TOTAL RETURN

     Calculation of the Fund's cumulative total return is not subject to a
standardized formula and represents the simple change in value of our
investment over a stated period and may be quoted as a percentage or as a
dollar amount.  Total returns and cumulative total returns may be broken down
into their components of income and capital (including capital gains and
changes in share price) in order to illustrate the relationship between these
factors and their contributions to total return.

     The Fund's performance figures are based upon historical results and do
not represent future results.  The Fund's shares are sold at net asset value
per share.  The Fund's returns and net asset value will fluctuate and shares
are redeemable at the then current net asset value of the Fund, which may be
more or less than original cost.  Factors affecting the Fund's performance
include general market conditions, operating expenses and investment
management.  Any additional fees charged by a dealer or other financial
services firm would reduce the returns described in this section.

COMPARISONS

(1)  U.S. TREASURY BILLS, NOTES, OR BONDS
     Investors may want to compare the performance of the Fund to that of U.S.
Treasury bills, notes or bonds, which are issued by the U.S. government.
Treasury obligations are issued in selected denominations.  Rates of Treasury
obligations are fixed at the time of issuance and payment of principal and
interest is backed by the full faith and credit of the United States Treasury.
The market value of such instruments will generally fluctuate inversely with
interest rates prior to maturity and will equal par value at maturity.
Generally, the values of obligations with shorter maturities will fluctuate
less than those with longer maturities.

(2)  CERTIFICATES OF DEPOSIT
     Investors may want to compare the Fund's performance to that of
certificates of deposit offered by banks and other depositary institutions.
Certificates of deposit may offer fixed or variable interest rates and
principal is guaranteed and may be insured. Withdrawal of the deposits prior to
maturity normally will be subject to a penalty.  Rates offered by banks and
other depositary institutions are subject to change at any time specified by
the issuing institution.

(3)  MONEY MARKET FUNDS
     Investors may also want to compare performance of the Fund to that of
money market funds.  Money market fund yields will fluctuate and shares are not
insured, but share values usually remain stable.

(4)  LIPPER ANALYTICAL SERVICES, INC. ("LIPPER") AND OTHER INDEPENDENT RANKING
     ORGANIZATIONS
     From time to time, in marketing and other fund literature, the Fund's
performance may be compared to the performance of other mutual funds in general
or to the performance of particular types of mutual funds, with similar
investment goals, as tracked by independent organizations.  Among these
organizations, Lipper, a widely used independent research firm which ranks
mutual funds by overall performance, investment objectives, and assets, may be
cited.  Lipper performance figures are based on changes in net asset value,
with all income and capital gain dividends reinvested.  Such calculations do
not include the effect of any sales charges imposed by other funds.  The Fund
will be compared to Lipper's appropriate fund category, that is, by fund
objective and portfolio holdings.  The Fund's performance may also be compared
to the average performance of its Lipper category.

(5)  MORNINGSTAR, INC.
     The Fund's performance may also be compared to the performance of other
mutual funds by Morningstar, Inc. which rates funds on the basis of historical
risk and total return.  Morningstar's ratings range from five stars (highest)
to one star (lowest) and represent Morningstar's assessment of the historical
risk level and total return of a fund as a weighted average for 3, 5, and 10
year periods.  Ratings are not absolute and do not represent future results.

(6)  INDEPENDENT SOURCES
     Evaluations of Fund performance made by independent sources may also be
used in advertisements concerning the Fund, including reprints of, or
selections from, editorials or articles about the Fund, especially those with
similar objectives.  Sources for Fund performance information and articles
about the Fund may include publications such as Money, Forbes, Kiplinger's,
Smart Money, Morningstar, Inc., Financial World, Business Week, U.S. News and
World Report, The Wall Street Journal, Barron's, and a variety of investment
newsletters.

(7)  VARIOUS BANK PRODUCTS
     The Fund's performance also may be compared on a before or after-tax basis
to various bank products, including the average rate of bank and thrift
institution money market deposit accounts, Super N.O.W. accounts and
certificates of deposit of various maturities as reported in the Bank Rate
Monitor, National Index of 100 leading banks, and thrift institutions as
published by the Bank Rate Monitor, Miami Beach, Florida.  The rates published
by the Bank Rate Monitor National Index are

                                     - 38 -

<PAGE>   78

averages of the personal account rates offered on the Wednesday prior to the
date of publication by 100 large banks and thrifts in the top ten Consolidated
Standard Metropolitan Statistical Areas.  The rates provided for the  bank
accounts assume no compounding and are for the lowest minimum deposit required
to open an account.  Higher rates may be available for larger deposits.

     With respect to money market deposit accounts and Super N.O.W. accounts,
account minimums range upward from $2,000 in each institution and compounding
methods vary.  Super N.O.W. accounts generally offer unlimited check writing
while money market deposit accounts generally restrict the number of checks
that may be written.  If more than one rate is offered, the lowest rate is
used.  Rates are determined by the financial institution and are subject to
change at any time specified by the institution.  Generally, the rates offered
for these products take market conditions and competitive product yields into
consideration when set.  Bank products represent a taxable alternative income
producing product.  Bank and thrift institution deposit accounts may be
insured.  Shareholder accounts in the Fund are not insured.  Bank passbook
savings accounts compete with money market mutual fund products with respect to
certain liquidity features but may not offer all of the features available from
a money market mutual fund, such as check writing.  Bank passbook savings
accounts normally offer a fixed rate of interest while the yield of the Fund
fluctuates.  Bank checking accounts normally do not pay interest but compete
with money market mutual fund products with respect to certain liquidity
features (e.g., the ability to write checks against the account).  Bank
certificates of deposit may offer fixed or variable rates for a set term.
(Normally, a variety of terms are available.)  Withdrawal of these deposits
prior to maturity will normally be subject to a penalty.  In contrast, shares
of the Fund are redeemable at the net asset value (normally, $1.00 per share)
next determined after a request is received, without charge.

(8)  INDICES
     The Fund may compare its performance to a wide variety of indices.  There
are differences and similarities between the investments which the Fund may
purchase and the investments measured by indices.

(9)  HISTORICAL ASSET CLASS RETURNS
     From time to time, marketing materials may portray the historical returns
of various asset classes.  Such presentations will typically compare the
average annual rates of return of inflation, U.S. Treasury bills, bonds, common
stocks, and small stocks. There are important differences between each of these
investments that should be considered in viewing any such comparison.  The
market value of stocks will fluctuate with market conditions, and small-stock
prices generally will fluctuate more than large-stock prices. Stocks are
generally more volatile than bonds.  In return for this volatility, stocks have
generally performed better than bonds or cash over time.  Bond prices generally
will fluctuate inversely with interest rates and other market conditions, and
the prices of bonds with longer maturities generally will fluctuate more than
those of shorter-maturity bonds. Interest rates for bonds may be fixed at the
time of issuance, and payment of principal and interest may be guaranteed by
the issuer and, in the case of U.S. Treasury obligations, backed by the full
faith and credit of the U.S. Treasury.

     The Advisor also serves as Advisor or Subadvisor to several management
investment companies, some of which fund variable annuity separate accounts of
certain insurance companies.

     The Fund may from time to time be compared to the other funds in the
Strong Family of Funds based on a risk/reward spectrum.  In general, the amount
of risk associated with any investment product is commensurate with that
product's potential level of reward. The Strong Funds risk/reward continuum or
any Fund's position on the continuum may be described or diagrammed in
marketing materials.  The Strong Funds risk/reward continuum positions the risk
and reward potential of each Strong Fund relative to the other Strong Funds,
but is not intended to position any Strong Fund relative to other mutual funds
or investment products. Marketing materials may also discuss the relationship
between risk and reward as it relates to an individual investor's portfolio.

     Financial goals vary from person to person.  You may choose one or more of
the Strong Funds to help you reach your financial goals.  To help you better
understand the Strong Income Funds and determine which Fund or combination of
Funds best meets your personal investment objectives, they are described in the
same Prospectus.

(10) TYING TIME FRAMES TO YOUR GOALS

     There are many issues to consider as you make your investment decisions,
including analyzing your risk tolerance, investing experience, and asset
allocations.  You should start to organize your investments by learning to link
your many financial goals to specific time frames.  Then you can begin to
identify the appropriate types of investments to help meet your goals.  As a
general rule of thumb, the longer your time horizon, the more price fluctuation
you will be able to tolerate in pursuit of higher returns.  For that reason,
many people with longer-term goals select stocks or long-term bonds, and many
people with nearer-term goals match those up with for instance, short-term
bonds.  The Advisor developed the following suggested holding periods to help
our investors set realistic expectations for both the risk and reward potential
of our funds.  (See table below.)  Of course, time is just one element to
consider when making your investment decision.

ADDITIONAL FUND INFORMATION

(1)  DURATION

     Duration is a calculation that seeks to measure the price sensitivity of a
bond or a bond fund to changes in interest rates.  It measures bond price
sensitivity to interest rate changes by taking into account the time value of
cash flows generated over the bond's life.  Future interest and principal
payments are discounted to reflect their present value and then are multiplied
by the number of years they will be received to produce a value that is
expressed in years.  Since duration can also be computed for the Fund, you can
estimate the effect of interest rates on the Fund's share price.  Simply
multiply the Fund's duration by an expected change in interest rates.  For
example, the price of the Fund with a duration of two years would be expected
to fall approximately two percent if market interest rates rose by one
percentage point.

(2)  PORTFOLIO CHARACTERISTICS

     In order to present a more complete picture of the Fund's portfolio,
marketing materials may include various actual or estimated portfolio
characteristics, including but not limited to median market capitalizations,
earnings per share, alphas, betas, price/earnings ratios, returns on equity,
dividend yields, capitalization ranges, growth rates, price/book ratios, top
holdings, sector breakdowns, asset allocations, quality breakdowns, and
breakdowns by geographic region.

(3)  MEASURES OF VOLATILITY AND RELATIVE PERFORMANCE

     Occasionally statistics may be used to specify Fund volatility or risk.
The general premise is that greater volatility connotes greater risk undertaken
in achieving performance.  Measures of volatility or risk are generally used to
compare the Fund's net asset value or performance relative to a market index.
One measure of volatility is beta.  Beta is the volatility of a fund relative
to the total market as represented by the Standard & Poor's 500 Stock Index.  A
beta of more than 1.00 indicates volatility greater than the market, and a beta
of less than 1.00 indicates volatility less than the market.  Another measure
of volatility or risk is standard deviation. Standard deviation is a
statistical tool that measures the degree to which a fund's performance has
varied from its average performance during a particular time period.

Standard deviation is calculated using the following formula:

                                                  2
Standard deviation = the square root of E(x  -  x)
                                           i    m
                                        -----------    
                                            n-1

where                E  =  "the sum of",
                     x  =  each individual return during the time period,
                      i
                     x  =  the average return over the time period, and
                      m

                     n  =  the number of individual returns during the time 
                           period.



     Statistics may also be used to discuss the Fund's relative performance.
One such measure is alpha. Alpha measures the actual return of a fund compared
to the expected return of a fund given its risk (as measured by beta).  The
expected return is based on how the market as a whole performed, and how the
particular fund has historically performed against the market. Specifically,
alpha is the actual return less the expected return. The expected return is
computed by multiplying the advance or decline in a market representation by
the fund's beta. A positive alpha quantifies the value that the fund manager
has added, and a negative alpha quantifies the value that the fund manager has
lost.

     Other measures of volatility and relative performance may be used as
appropriate. However, all such measures will fluctuate and do not represent
future results.

                              GENERAL INFORMATION

BUSINESS PHILOSOPHY

     The Advisor is an independent, Midwestern-based investment advisor, owned
by professionals active in its management. Recognizing that investors are the
focus of its business, the Advisor strives for excellence both in investment
management and in the service provided to investors. This commitment affects
many aspects of the business, including professional staffing, product
development, investment management, and service delivery.

     The increasing complexity of the capital markets requires specialized
skills and processes for each asset class and style. Therefore, the Advisor
believes that active management should produce greater returns than a passively
managed index.  The Advisor has brought together a group of top-flight
investment professionals with diverse product expertise, and each concentrates
on their investment specialty. The Advisor believes that people are the firm's
most important asset. For this reason, continuity of professionals is critical
to the firm's long-term success.

INVESTMENT ENVIRONMENT

     Discussions of economic, social, and political conditions and their impact
on the Fund may be used in advertisements and sales materials.  Such factors
that may impact the Fund include, but are not limited to, changes in interest
rates, political developments, the competitive environment, consumer behavior,
industry trends, technological advances, macroeconomic trends, and the supply
and demand of various financial instruments.  In addition, marketing materials
may cite the portfolio management's views or interpretations of such factors.

EIGHT BASIC PRINCIPLES FOR SUCCESSFUL MUTUAL FUND INVESTING

     These common sense rules are followed by many successful investors. They
make sense for beginners, too. If you have a question on these principles, or
would like to discuss them with us, please contact us at 1-800-368-3863.

1.   Have a plan - even a simple plan can help you take control of your
     financial future. Review your plan once a year, or if your circumstances
     change.

2.   Start investing as soon as possible. Make time a valuable ally. Let it
     put the power of compounding to work for you, while helping to reduce your
     potential investment risk.

3.   Diversify your portfolio. By investing in different asset classes -
     stocks, bonds, and cash - you help protect against poor performance in one
     type of investment while including investments most likely to help you
     achieve your important goals.

4.   Invest regularly. Investing is a process, not a one-time event. By
     investing regularly over the long term, you reduce the impact of
     short-term market gyrations, and you attend to your long-term plan before
     you're tempted to spend those assets on short-term needs.

5.   Maintain a long-term perspective. For most individuals, the best
     discipline is staying invested as market conditions change. Reactive,
     emotional investment decisions are all too often a source of regret - and
     principal loss.

6.   Consider stocks to help achieve major long-term goals. Over time, stocks
     have provided the more powerful returns needed to help the value of your
     investments stay well ahead of inflation.

7.   Keep a comfortable amount of cash in your portfolio. To meet current
     needs, including emergencies, use a money market fund or a bank account -
     not your long-term investment assets.

8.   Know what you're buying. Make sure you understand the potential risks and
     rewards associated with each of your investments. Ask questions... request
     information...make up your own mind. And choose a fund company that helps
     you make informed investment decisions.

STRONG RETIREMENT PLAN SERVICES

     Strong Retirement Plan Services offers a full menu of high quality,
affordable retirement plan options, including traditional money purchase
pension and profit sharing plans, 401(k) plans, simplified employee pension
plans, salary reduction plans, Keoghs, and 403(b) plans.  Retirement plan
specialists are available to help companies determine which type of retirement
plan may be appropriate for their particular situation.

Markets:

     The retirement plan services provided by the Advisor focus on four
distinct markets, based on the belief that a retirement plan should fit the
customer's needs, not the other way around.

1.   Small company plans.  Small company plans are designed for companies with
     1-50 plan participants.  The objective is to incorporate the features and
     benefits typically reserved for large companies, such as sophisticated
     recordkeeping systems, outstanding service, and investment expertise, into
     a small company plan without administrative hassles or undue expense.
     Small company plan sponsors receive a comprehensive plan administration
     manual as well as toll-free telephone support.

2.   Large company plans.  Large company plans are designed for companies with
     between 51 and 1,000 plan participants.  Each large company plan is
     assigned a team of professionals consisting of an account manager, who is
     typically an attorney, CPA, or holds a graduate degree in business, a
     conversion specialist (if applicable), an accounting manager, a
     legal/technical manager, and an education/communications educator.

                                     - 43 -

3. Women-owned businesses.

4. Non-profit and educational organizations (the 403(b) market).

Turnkey approach:

     The retirement plans offered by the Advisor are designed to be streamlined
and simple to administer.  To this end, the Advisor has invested heavily in the
equipment, systems, and people necessary to adopt or convert a plan, and to
keep it running smoothly.  The Advisor provides all aspects of the plan,
including plan design, administration, recordkeeping, and investment
management.  To streamline plan design, the Advisor provides customizable
IRS-approved prototype documents.  The Advisor's services also include annual
government reporting and testing as well as daily valuation of each
participant's account.  This structure is intended to eliminate the confusion
and complication often associated with dealing with multiple vendors.  It is
also designed to save plan sponsors time and expense.

     The Advisor strives to provide one-stop retirement savings programs that
combine the advantages of proven investment management, flexible plan design
and a wide range of investment options.  The open architecture design of the
plans allow for the use of the family of mutual funds managed by the Advisor as
well as a stable asset value option.  Large company plans may supplement these
options with their company stock (if publicly traded) or funds from other
well-known mutual fund families.

Education:

     Participant education and communication is key to the success of any
retirement program, and therefore is one of the most important services that
the Advisor provides.  The Advisor's goal is twofold: to make sure that plan
participants fully understand their options and to educate them about the
lifelong investment process.  To this end, the Advisor provides attractive,
readable print materials that are supplemented with audio and video tapes and
retirement education programs.

Service:

     The Advisor's goal is to provide a world class level of service.  One
aspect of that service is an experienced, knowledgeable team that provides
ongoing support for plan sponsors, both at adoption or conversion and
throughout the life of a plan.  The Advisor is committed to delivering accurate
and timely information, evidenced by straightforward, complete, and
understandable reports, participant account statements and plan summaries.

     The Advisor has designed both "high-tech" and "high-touch" systems,
providing an automated telephone system as well as personal contact.
Participants can access daily account information, conduct transactions, or
have questions answered in the way that is most comfortable for them.

                              PORTFOLIO MANAGEMENT

     Each portfolio manager works with a team of analysts, traders, and
administrative personnel. From time to time, marketing materials may discuss
various members of the team, including their education, investment experience,
and other credentials.

                                     - 44 -

<PAGE>   84



     The Advisor believes that actively managing the Fund's portfolio and
adjusting the average portfolio maturity according to the Advisor's interest
rate outlook is the best way to achieve the Fund's objectives.  This policy is
based on a fundamental belief that economic and financial conditions create
favorable and unfavorable investment periods (or seasons) and that these
different seasons require different investment approaches. Through its active
management approach, the Advisor seeks to avoid or reduce any negative change
in the Fund's net asset value per share during the periods of falling bond
prices and provide consistently positive annual returns throughout the seasons
of investment.

The Advisor's investment philosophy includes the following basic beliefs:


- -    Active management pursued by a team with a uniform discipline across the 
     fixed income spectrum can produce results that are superior to those 
     produced through passive management.
- -    Controlling risk by making only moderate deviations from the defined 
     benchmark is the cornerstone of successful fixed incom investing.
- -    Successful fixed income management is best pursued on a top-down basis 
     utilizing fundamental techniques.


The investment process includes decisions made at four levels that are
consistent with the Advisor's viewpoint of the path of economic activity,
interest rates, and the supply of and demand for credit.

The goal is to derive equivalent amounts of excess performance and risk control
over the long run from each of the four levels of decision-making:

1.   Duration.  The Fund's portfolio duration is managed within a range
     relative to its respective benchmark.
2.   Yield Curve. Modest overweights and underweights along the yield curve
     are made to benefit from changes in the yield curve's shape.
3.   Sector/Quality. Sector weightings are generally maintained between zero
     and two times those of the benchmark.
4.   Security Selection.  Quantitative analysis drives issue selection in the
     Treasury and mortgage marketplace. Proactive credit research drives
     corporate issue selection.

Risk control is pursued at three levels:

1.   Portfolio structure.  In structuring the portfolio, the Advisor carefully
     considers such factors as position sizes, duration, benchmark
     characteristics, and the use of illiquid securities.
2.   Credit research. Proactive credit research is used to identify issues
     which the Advisor believes will be candidates for credit upgrade. This
     research includes visiting company management, establishing appropriate
     values for credit ratings, and monitoring yield spread relationships.
3.   Portfolio monitoring. Portfolio fundamentals are re-evaluated
     continuously, and buy/sell targets are established and generally adhered
     to.

                                    APPENDIX

                                  BOND RATINGS

                         STANDARD & POOR'S DEBT RATINGS

     A Standard & Poor's corporate or municipal debt rating is a current
assessment of the creditworthiness of an obligor with respect to a specific
obligation.  This assessment may take into consideration obligors such as
guarantors, insurers, or lessees.

     The debt rating is not a recommendation to purchase, sell, or hold a
security, inasmuch as it does not comment as to market price or suitability for
a particular investor.

     The ratings are based on current information furnished by the issuer or
obtained by S&P from other sources it considers reliable.  S&P does not perform
an audit in connection with any rating and may, on occasion, rely on unaudited
financial information.  The ratings may be changed, suspended, or withdrawn as
a result of changes in, or unavailability of, such information, or based on
other circumstances.

     The ratings are based, in varying degrees, on the following
considerations:

             1.   Likelihood of default capacity and willingness
                  of the obligor as to the timely payment of interest and
                  repayment of principal in accordance with the terms of the
                  obligation.

             2.   Nature of and provisions of the obligation.

             3.   Protection afforded by, and relative position
                  of, the obligation in the event of bankruptcy,
                  reorganization, or other arrangement under the laws of
                  bankruptcy and other laws affecting creditors' rights.

INVESTMENT GRADE
     AAA Debt rated 'AAA' has the highest rating assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.

     AA Debt rated 'AA' has a very strong capacity to pay interest and repay
principal and differs from the highest rated issues only in small degree.

     A Debt rated 'A' has a strong capacity to pay interest and repay
principal, although it is somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than debt in higher-rated
categories.

     BBB Debt rated 'BBB' is regarded as having an adequate capacity to pay
interest and repay principal.  Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher-rated categories.

SPECULATIVE GRADE
     Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded as having
predominantly speculative characteristics with respect to capacity to pay
interest and repay principal.  'BB' indicates the least degree of speculation
and 'C' the highest.  While such debt will likely have some quality and
protective characteristics, these are outweighed by large uncertainties or
major exposures to adverse conditions.

     BB Debt rated 'BB' has less near-term vulnerability to default than other
speculative issues.  However, it faces major ongoing uncertainties or exposure
to adverse business, financial, or economic conditions which could lead to
inadequate capacity to meet timely interest and principal payments.  The 'BB'
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied 'BBB-' rating.

                                      A-1


<PAGE>   86





     B Debt rated 'B' has a greater vulnerability to default but currently has
the capacity to meet interest payments and principal repayments.  Adverse
business, financial, or economic conditions will likely impair capacity or
willingness to pay interest and repay principal.  The 'B' rating category is
also used for debt subordinated to senior debt that is assigned an actual or
implied 'BB' or 'BB-' rating.

     CCC Debt rated 'CCC' has a currently identifiable vulnerability to
default, and is dependent upon favorable business, financial, and economic
conditions to meet timely payment of interest and repayment of principal.  In
the event of adverse business, financial, or economic conditions, it is not
likely to have the capacity to pay interest and repay principal.  The 'CCC'
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied 'B' or 'B-' rating.

     CC Debt rated 'CC' typically is applied to debt subordinated to senior
debt that is assigned an actual or implied 'CCC' rating.

     C Debt rated 'C' typically is applied to debt subordinated to senior debt
which is assigned an actual or implied  'CCC-' rating.  The 'C' rating may be
used to cover a situation where a bankruptcy petition has been filed, but debt
service payments are continued.

     CI The rating 'CI' is reserved for income bonds on which no interest is
being paid.

     D  Debt rated 'D' is in payment default.  The 'D' rating category is used
when interest payments or principal payments are not made on the date due, even
if the applicable grace period has not expired, unless S&P believes that such
payments will be made during such grade period.  The 'D' rating also will be
used upon the filing of a bankruptcy petition if debt service payments are
jeopardized.

                         MOODY'S LONG-TERM DEBT RATINGS

     Aaa  - Bonds which are rated Aaa are judged to be of the best quality.
They carry the smallest degree of investment risk and are generally referred to
as "gilt edged".  Interest payments are protected by a large or by an
exceptionally stable margin and principal is secure.  While the various
protective elements are likely to change, such changes as can be visualized are
most unlikely to impair the fundamentally strong position of such issues.

     Aa - Bonds which are rated Aa are judged to be of high quality by all
standards.  Together with the Aaa group they comprise what are generally known
as high grade bonds.  They are rated lower than the best bonds because margins
of protection may not be as large as in Aaa securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risk appear somewhat larger than in Aaa
securities.

     A - Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper-medium grade obligations.  Factors giving
security to principal and interest are considered adequate, but elements may be
present which suggest a susceptibility to impairment some time in the future.

     Baa - Bonds which are rated Baa are considered as medium-grade obligations
(i.e., 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 bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.

     Ba - Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well-assured. Often the protection of
interest and principal payments may be very moderate, and thereby not well
safeguarded during both good and bad times over the future.  Uncertainty of
position characterizes bonds in this class.

     B - Bonds which are rated B generally lack characteristics of the
desirable investment.  Assurance of interest and principal payments or
maintenance of other terms of the contract over any long period of time may be
small.

                                      A-2


<PAGE>   87





     Caa - Bonds which are rated Caa are of poor standing.  Such issues may be
in default or there may be present elements of danger with respect to principal
or interest.

     Ca - Bonds which are rated Ca represent obligations which are speculative
in a high degree.  Such issues are often in default or have other marked
shortcomings.

     C - Bonds which are rated C are the lowest rated class of bonds, and
issues so rated can be regarded as having extremely poor prospects of ever
attaining any real investment standing.

                   FITCH INVESTORS SERVICE, INC. BOND RATINGS

     Fitch investment grade bond and preferred stock ratings provide a guide to
investors in determining the credit risk associated with a particular security.
The ratings represent Fitch's assessment of the issuer's ability to meet the
obligations of a specific debt or preferred issue in a timely manner.

     The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the
issuer's future financial strength and credit quality.

     Fitch ratings do not reflect any credit enhancement that may be provided
by insurance policies or financial guaranties unless otherwise indicated.

     Bonds and preferred stock carrying the same rating are of similar but not
necessarily identical credit quality since the rating categories do not fully
reflect small differences in the degrees of credit risk.

     Fitch ratings are not recommendations to buy, sell, or hold any security.
Ratings do not comment on the adequacy of market price, the suitability of any
security for a particular investor, or the tax-exempt nature or taxability of
payments made in respect of any security.

     Fitch ratings are based on information obtained from issuers, other
obligors, underwriters, their experts, and other sources Fitch believes to be
reliable.  Fitch does not audit or verify the truth or accuracy of such
information.  Ratings may be changed, suspended, or withdrawn as a result of
changes in, or the unavailability of, information or for other reasons.

       AAA  Bonds and preferred stock considered to be investment grade
            and of the highest credit quality.  The obligor has an
            exceptionally strong ability to pay interest and/or dividends and
            repay principal, which is unlikely to be affected by reasonably
            foreseeable events.

       AA   Bonds and preferred stock considered to be investment grade
            and of very high credit quality.  The obligor's ability to pay
            interest and/or dividends and repay principal is very strong,
            although not quite as strong as bonds rated 'AAA'.  Because bonds
            and preferred stock rated in the 'AAA'  and 'AA' categories are not
            significantly vulnerable to foreseeable future developments,
            short-term debt of the issuers is generally rated 'F-1+'.

       A    Bonds and preferred stock considered to be investment
            grade and of high credit quality.  The obligor's ability to pay
            interest and/or dividends and repay principal is considered to be
            strong, but may be more vulnerable to adverse changes in economic
            conditions and circumstances than debt or preferred securities
            with higher ratings.

       BBB  Bonds and preferred stock considered to be investment grade
            and of satisfactory credit quality.  The obligor's ability to pay
            interest or dividends and repay principal is considered to be
            adequate.  Adverse changes in economic conditions and
            circumstances, however, are more likely to have adverse impact on
            these securities and, therefore, impair timely payment.  The
            likelihood that the

                                      A-3


<PAGE>   88



             ratings of these bonds or preferred will fall below investment
             grade is higher than for securities with higher ratings.

     Fitch speculative grade bond or preferred stock ratings provide a guide to
investors in determining the credit risk associated with a particular security.
The ratings ('BB' to 'C') represent Fitch's assessment of the likelihood of
timely payment of principal and interest or dividends in accordance with the
terms of obligation for issues not in default.  For defaulted bonds or
preferred stock, the rating ('DDD' to 'D') is an assessment of the ultimate
recovery value through reorganization or liquidation.

     The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer or possible recovery value in
bankruptcy, the current  and prospective financial condition and operating
performance of the issuer and any guarantor, as well as the economic and
political environment that might affect the issuer's future financial strength.

     Bonds or preferred stock that have the same rating are of similar but not
necessarily identical credit quality since the rating categories cannot fully
reflect the differences in the degrees of credit risk.


       BB        Bonds or preferred stock are considered speculative.  The
                 obligor's ability to pay interest or dividends and repay
                 principal may be affected over time by adverse economic
                 changes.  However, business and financial alternatives can be
                 identified, which could ssist the obligor in satisfying its
                 debt service requirements.
            
        B        Bonds or preferred stock are considered highly speculative.
                 While bonds in this class are currently meeting debt service
                 requirements or paying dividends, the probability of continued
                 timely payment of principal and interest reflects the obligor's
                 limited margin of safety and the need for reasonable business
                 and economic activity throughout the life of the issue.
            
       CCC       Bonds or preferred stock have certain identifiable
                 characteristics that, if not remedied, may lead to default.
                 The ability to meet obligations requires an advantageous
                 business and economic environment.
            
       CC        Bonds or preferred stock are minimally protected.  Default
                 in payment of interest and/or principal seems probable over
                 time.
            
        C        Bonds are in imminent default in payment of interest or
                 principal or suspension of preferred stock dividends is
                 imminent.

      DDD, DD,
      and        D Bonds are in default on interest and/or principal payments
                 or preferred stock dividends are suspended.  Such securities
                 are extremely speculative and should be valued on the basis of
                 their ultimate recovery value in liquidation or reorganization
                 of the obligor.  'DDD' represents the highest potential for
                 recovery of these securities, and 'D' represents the lowest
                 potential for recovery.
      
                   DUFF & PHELPS, INC. LONG-TERM DEBT RATINGS
      
     These ratings represent a summary opinion of the issuer's long-term
fundamental quality.  Rating determination is based on qualitative and
quantitative factors which may vary according to the basic economic and
financial characteristics of each industry and each issuer.  Important
considerations are vulnerability to economic cycles as well as risks related to
such factors as competition, government action, regulation, technological
obsolescence, demand shifts, cost structure, and management depth and expertise.
The projected viability of the obligor at the trough of the cycle is a critical
determination.

     Each rating also takes into account the legal form of the security, (e.g.,
first mortgage bonds, subordinated debt, preferred stock, etc.).  The extent of
rating dispersion among the various classes of securities is determined by
several factors including relative weightings of the different security classes
in the capital structure, the overall credit strength of the issuer, and the
nature of covenant protection.  Review of indenture restrictions is important
to the analysis of a company's operating and financial constraints.  From time
to time, Duff & Phelps Credit Rating Co. places issuers or security classes on
Rating Watch.  The Rating Watch Status results from a need to notify investors
and the issuer that there are conditions present leading us to re-evaluate the
current rating(s).  A listing on Rating Watch, however, does not mean a rating
change is inevitable.  The Rating Watch Status can either be resolved quickly
or over a longer period of time, depending on the reasons surrounding the
placement on Rating Watch.  The "up" designation means a rating may be
upgraded; the "down" designation means a rating may be downgraded, and the
uncertain designation means a rating may be raised or lowered.

     The Credit Rating Committee formally reviews all ratings once per quarter
(more frequently, if necessary).   Ratings of 'BBB-' and higher fall within the
definition of investment grade securities, as defined by bank and insurance
supervisory authorities.  Structured finance issues, including real estate,
asset-backed and mortgage-backed financings, use this same rating scale with
minor modification in the definitions.  Thus, an investor can compare the
credit quality of investment alternatives across industries and structural
types.  A "Cash Flow Rating" (as noted for specific ratings) addresses the
likelihood that aggregate principal and interest will equal or exceed the rated
amount under appropriate stress conditions.

                          IBCA LONG-TERM DEBT RATINGS

     AAA - Obligations for which there is the lowest expectation of investment
risk.  Capacity for timely repayment of  principal and interest is substantial,
such that adverse changes in business, economic or financial conditions are
unlikely to increase investment risk substantially.

     AA - Obligations for which there is a very low expectation of investment
risk.  Capacity for timely repayment of principal and interest is substantial.
Adverse changes in business, economic or financial conditions may increase
investment risk, albeit not very significantly.

     A - Obligations for which there is a low expectation of investment risk.
Capacity for timely repayment of principal and interest is strong, although
adverse changes in business, economic or financial conditions may lead to
increased investment risk.

     BBB - Obligations for which there is currently a low expectation of
investment risk.  Capacity for timely repayment of principal and interest is
adequate, although adverse changes in business, economic or financial
conditions are more likely to lead to increased investment risk than for
obligations in other categories.

     BB - Obligations for which there is a possibility of investment risk
developing.  Capacity for timely repayment of principal and interest exists,
but is susceptible over time to adverse changes in business, economic or
financial conditions.

     B - Obligations for which investment risk exists.  Timely repayment of
principal and interest is not sufficiently protected against adverse changes in
business, economic or financial conditions.

     CCC - Obligations for which there is a current perceived possibility of
default.  Timely repayment of principal and interest is dependent on favorable
business, economic or financial conditions.

     CC - Obligations which are highly speculative or which have a high risk of
default.

     C - Obligations which are currently in default.

     NOTES: "+" or "-" may be appended to a rating below AAA to denote relative
status within major rating categories.  Ratings of BB and below are assigned
where it is considered that speculative characteristics are present.

                    THOMSON BANKWATCH LONG-TERM DEBT RATINGS

     Long-Term Debt Ratings assigned by Thomson BankWatch also weigh heavily
government ownership and support.  The quality of both the company's management
and franchise are of even greater importance in the Long-Term Debt Rating
decisions.  Long-Term Debt Ratings look out over a cycle and are not adjusted
frequently for what we believe are short-term performance aberrations.

     Long-Term Debt Ratings can be restricted to local currency debt - ratings
will be identified by the designation LC.  In addition, Long-Term Debt Ratings
may include a plus (+) or minus (-) to indicate where within the category the
issue is placed.  BankWatch Long-Term Debt Ratings are based on the following
scale:

Investment Grade

     AAA (LC-AAA) - Indicates that the ability to repay principal and interest
on a timely basis is extremely high.

     AA (LC-AA) - Indicates a very strong ability to repay principal and
interest on a timely basis, with limited incremental risk compared to issues
rated in the highest category.

     A (LC-A) - Indicates the ability to repay principal and interest is
strong.  Issues rated A could be more vulnerable to adverse developments (both
internal and external) than obligations with higher ratings.

     BBB (LC-BBB) - The lowest investment-grade category; indicates an
acceptable capacity to repay principal and interest.  BBB issues are more
vulnerable to adverse developments (both internal and external) than
obligations with higher ratings.

Non-Investment Grade - may be speculative in the likelihood of timely repayment
of principal and interest

     BB (LC-BB) - While not investment grade, the BB rating suggests that the
likelihood of default is considerably less than for lower-rated issues.
However, there are significant uncertainties that could affect the ability to
adequately service debt obligations.

     B (LC-B) - Issues rated B show higher degree of uncertainty and therefore
greater likelihood of default than higher-rated issues.  Adverse developments
could negatively affect the payment of interest and principal on a timely
basis.

     CCC (LC-CCC) - Issues rated CCC clearly have a high likelihood of default,
with little capacity to address further adverse changes in financial
circumstances.

     CC (LC-CC) - CC is applied to issues that are subordinate to other
obligations rated CCC and are afforded less protection in the event of
bankruptcy or reorganization.

     D (LC-D) - Default.

                               SHORT-TERM RATINGS

                   STANDARD & POOR'S COMMERCIAL PAPER RATINGS

     A Standard & Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt considered short-term in the relevant
market.

     Ratings are graded into several categories, ranging from 'A-1' for the
highest quality obligations to 'D' for the lowest.  These categories are as
follows:

                                      A-7


<PAGE>   92





     A-1 This highest category indicates that the degree of safety regarding
timely payment is strong.  Those issues determined to possess extremely strong
safety characteristics are denoted with a plus sign (+) designation.

     A-2 Capacity for timely payment on issues with this designation is
satisfactory.  However, the relative degree of safety is not as high as for
issues designated 'A-1'.

     A-3 Issues carrying this designation have adequate capacity for timely
payment.  They are, however, more vulnerable to the adverse effects of changes
in circumstances than obligations carrying the higher designations.

     B Issues rated 'B' are regarded as having only speculative capacity for
timely payment.

     C This rating is assigned to short-term debt obligations with doubtful
capacity for payment.

     D Debt rated 'D' is in payment default.  The 'D' rating category is used
when interest payments or principal payments are not made on the date due, even
if the applicable grace period has not expired, unless S&P believes that such
payments will be made during such grace period.

                         STANDARD & POOR'S NOTE RATINGS

     An S&P note rating reflects the liquidity factors and market-access risks
unique to notes.  Notes maturing 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 following criteria will be used in making the assessment:

      -    Amortization schedule - the larger the final maturity
           relative to other maturities, the more likely the issue is to be
           treated as a note.

      -    Source of payment - the more the issue depends on the market
           for its refinancing, the more likely it is to be treated as a note.

     Note rating symbols and definitions are as follows:

     SP-1 Strong capacity to pay principal and interest.  Issues determined to
possess very strong characteristics are given a plus (+) designation.

     SP-2 Satisfactory capacity to pay principal and interest, with some
vulnerability to adverse financial and economic changes over the term of the
notes.

     SP-3 Speculative capacity to pay principal and interest.

                           MOODY'S SHORT-TERM RATINGS

     Moody's short-term debt ratings are opinions of the ability of issuers to
repay punctually senior debt obligations.  These obligations have an original
maturity not exceeding one year, unless explicitly noted.

     Moody's employs the following three designations, all judged to be
investment grade, to indicate the relative repayment ability of rated issuers:

     Issuers rated Prime-1 (or supporting institutions) have a superior ability
for repayment of senior short-term debt obligations.  Prime-1 repayment ability
will often be evidenced by many of the following characteristics:  (i) leading
market positions in well-established industries, (ii) high rates of return on
funds employed, (iii) conservative capitalization structure with moderate
reliance on debt and ample asset protection, (iv) broad margins in earnings
coverage of fixed financial charges and high internal cash generation, and (v)
well established access to a range of financial markets and assured sources of
alternate liquidity.

                                      A-8


<PAGE>   93





     Issuers rated Prime-2 (or supporting institutions) have a strong ability
for repayment of senior short-term debt obligations.  This will normally be
evidenced by many of the characteristics cited above, but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation.  Capitalization characteristics, while still appropriate, may be
more affected by external conditions.  Ample alternate liquidity is maintained.

     Issuers rated Prime-3 (or supporting institutions) have an acceptable
ability for repayment of senior short-term obligations.  The effect of industry
characteristics and market compositions may be more pronounced.  Variability in
earnings and profitability may result in changes in the level of debt
protection measurements and may require relatively high financial leverage.
Adequate alternate liquidity is maintained.

     Issuers rated Not Prime do not fall within any of the Prime rating
categories.

                FITCH INVESTORS SERVICE, INC. SHORT-TERM RATINGS

     Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of generally up to three years, including
commercial paper, certificates of deposit, medium-term notes, and municipal and
investment notes.

     The short-term rating places greater emphasis than a long-term rating on
the existence of liquidity necessary to meet the issuer's obligations in a
timely manner.

      F-1+ Exceptionally Strong Credit Quality.  Issues assigned this
           rating are regarded as having the strongest degree of assurance for
           timely payment.

      F-1  Very Strong Credit Quality.  Issues assigned this rating
           reflect an assurance of timely payment only slightly less in degree
           than issues rated 'F-1+'.

      F-2  Good Credit Quality.  Issues assigned this rating have a
           satisfactory degree of assurance for timely payment but the margin
           of safety is not as great as for issues assigned 'F-1+' and 'F-1'
           ratings.

      F-3  Fair Credit Quality.  Issues assigned this rating have
           characteristics suggesting that the degree of assurance for timely
           payment is adequate; however, near-term adverse changes could cause
           these securities to be rated below investment grade.

      F-S  Weak Credit Quality.  Issues assigned this rating have
           characteristics suggesting a minimal degree of assurance for timely

           and economic conditions.

      D    Default.  Issues assigned this rating are in actual or

                  DUFF & PHELPS, INC. SHORT-TERM DEBT RATINGS

     Duff & Phelps' short-term ratings are consistent with the rating criteria
used by money market participants.  The ratings apply to all obligations with
maturities of under one year, including commercial paper, the uninsured portion
of certificates of deposit, unsecured bank loans, master notes, bankers
acceptances, irrevocable letters of credit, and current maturities of long-term
debt.  Asset-backed commercial paper is also rated according to this scale.

     Emphasis is placed on liquidity which is defined as not only cash from
operations, but also access to alternative sources of funds including trade
credit, bank lines, and the capital markets.  An important consideration is the
level of an obligor's reliance on short-term funds on an ongoing basis.

     The distinguishing feature of Duff & Phelps' short-term ratings is the
refinement of the traditional '1' category.  The majority of short-term debt
issuers carry the highest rating, yet quality differences exist within that
tier.  As a consequence, Duff & Phelps has incorporated gradations of '1+' (one
plus) and '1-' (one minus) to assist investors in recognizing those
differences.

     From time to time, Duff & Phelps places issuers or security classes on
Rating Watch.  The Rating Watch status results from a need to notify investors
and the issuer that there are conditions present leading us to re-evaluate the
current rating(s).  A listing on Rating Watch, however, does not mean a rating
change is inevitable.

     The Rating Watch status can either be resolved quickly or over a longer
period of time, depending on the reasons surrounding the placement on Rating
Watch.  The "up" designation means a rating may be upgraded; the "down"
designation means a rating may be downgraded, and the "uncertain" designation
means a rating may be raised or lowered.


     Rating Scale:  Definition
     -------------  ----------

                    High Grade
                    ----------


     D-1+           Highest certainty of timely payment.  Short-Term liquidity,
                    including internal operating factors and/or access to
                    alternative sources of funds, is outstanding, and safety is
                    just below risk-free U.S. Treasury short-term obligations.

     D-1            Very high certainty of timely payment.  Liquidity factors
                    are excellent and supported by good fundamental protection
                    factors. Risk factors are minor.

     D-1-           High certainty of timely payment.  Liquidity factors are
                    strong and supported by good fundamental protection factors.
                    Risk factors are very small.

                    Good Grade

     D-2            Good certainty of timely payment.  Liquidity factors and
                    company fundamentals are sound.  Although ongoing funding
                    needs may enlarge total financing requirements, access to
                    capital markets is good.  Risk factors are small.

                    Satisfactory Grade

     D-3            Satisfactory liquidity and other protection factors qualify
                    issues as to investment grade.  Risk factors are larger and
                    subject to more variation. Nevertheless, timely payment is
                    expected.

                    Non-Investment Grade

     D-4            Speculative investment characteristics.  Liquidity is not
                    sufficient to insure against disruption in debt service.
                    Operating factors and market access may be subject to a high
                    degree of variation.

                    Default

     D-5            Issuer failed to meet scheduled principal and/or interest
                    payments.

                   THOMSON BANKWATCH (TBW) SHORT-TERM RATINGS

     The TBW Short-Term Ratings apply, unless otherwise noted, to specific debt
instruments of the rated entities with a maturity of one year or less.  TBW
Short-Term Ratings are intended to assess the likelihood of an untimely or
incomplete payments of principal or interest.

     TBW-1  The highest category; indicates a very high likelihood that
principal and interest will be paid on a timely basis.

     TBW-2  The second highest category; while the degree of safety regarding
timely repayment of principal and interest is strong, the relative degree of
safety is not as high as for issues rated "TBW-1".

     TBW-3  The lowest investment-grade category; indicates that while the
obligation is more susceptible to adverse developments (both internal and
external) than those with higher ratings, the capacity to service principal and
interest in a timely fashion is considered adequate.

     TBW-4  The lowest rating category; this rating is regarded as
non-investment grade and therefore speculative.

                            IBCA SHORT-TERM RATINGS

     IBCA Short-Term Ratings assess the borrowing characteristics of banks and
corporations, and the capacity for timely repayment of debt obligations.  The
Short-Term Ratings relate to debt which has a maturity of less than one year.

     A1      Obligations supported by the highest capacity for timely repayment.
             Where issues possess a particularly strong credit feature, a
             rating of A1+ is assigned.


     A2      Obligations supported by a good capacity for timely repayment.

     A3      Obligations supported by a satisfactory capacity for timely 
             repayment.


     B       Obligations for which there is an uncertainty as to the capacity to
             ensure timely repayment.

     C       Obligations for which there is a high risk of default or which are
             currently in default.
