BEA Institutional Funds is the name under which the Institutional class of
shares of certain Warburg Pincus Funds are offered. Eight BEA Institutional
Funds are described in this Prospectus:

EMERGING MARKETS II FUND seeks to provide long-term appreciation of capital. The
Fund will invest primarily in equity securities in emerging country markets.

HIGH YIELD FUND seeks to provide high total return. The Fund will invest
primarily in high yield high risk fixed income securities issued by
corporations, governments and agencies, both domestic and foreign.

INTERNATIONAL GROWTH FUND seeks to provide long-term appreciation of capital.
The Fund will invest primarily in equity securities of non-U.S. issuers.

MUNICIPAL BOND FUND seeks to provide high total return. The Fund will invest
primarily in municipal bonds issued by state and local authorities.

SELECT ECONOMIC VALUE EQUITY FUND seeks to provide long term appreciation of
capital. The Fund will invest primarily in U.S. equity securities that the
adviser believes are undervalued.

STRATEGIC GLOBAL FIXED INCOME FUND seeks to provide high total return. The Fund
will invest primarily in foreign and domestic fixed income securities.

U.S. CORE EQUITY FUND seeks to provide long-term appreciation of capital. The
Fund will invest primarily in U.S. equity securities.

U.S. CORE FIXED INCOME FUND seeks to provide high total return. The Fund will
invest primarily in domestic fixed-income securities consistent with comparable
broad market fixed-income indices, such as the Lehman Brothers Aggregate Bond
Index.

International investing entails special risk considerations, including currency
fluctuations, lower liquidity, economic instability, political uncertainty and
differences in accounting methods.

The High Yield Fund may invest its assets without limitation in securities which
are below investment-grade quality. Investments of this type are subject to
greater risks, including the risk of loss of principal and interest, than those
involved with investment-grade securities. Purchasers should carefully assess
the risks associated with an investment in this Fund.

See "Risk Factors and Special Considerations."

BEA Associates ("BEA") serves as investment adviser to each of the Funds.

This Prospectus briefly sets forth certain information about the Funds that
investors should know before investing. Investors are advised to read this
Prospectus and retain it for future reference. Additional information about each
Fund has been filed with the Securities and Exchange Commission (the "SEC"). The
SEC maintains a Web site (www.sec.gov) that contains the Statement of Additional
Information, material incorporated by reference and other information regarding
the Funds. The Statement of Additional Information is available to investors
without charge by calling BEA Institutional Funds at 800-401-2230. Information
regarding the status of shareholder accounts may be obtained by calling BEA
Institutional Funds at the same number. BEA Institutional Funds maintains a Web
site at www.beafunds.com. The Statement of Additional Information, as amended or
supplemented from time to time, bears the same date as this Prospectus and is
incorporated by reference in its entirety into this Prospectus.

SHARES OF THE FUNDS ARE NOT DEPOSITS OR OBLIGATIONS OF OR GUARANTEED OR ENDORSED
BY ANY BANK, AND SHARES ARE NOT FEDERALLY INSURED BY THE FEDERAL DEPOSIT
INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD OR ANY OTHER AGENCY.
INVESTMENTS IN SHARES OF THE FUNDS INVOLVE INVESTMENT RISKS, INCLUDING THE
POSSIBLE LOSS OF THE PRINCIPAL AMOUNT INVESTED.

EXAMPLE
  You would pay the following expenses
        on a $1,000 investment, assuming
  (1) 5% annual return and (2) redemption
        at the end of each time period:
   1 year........................................    $  15     $    7    $   12     $   10    $   10    $    8    $   10    $    5

   5 years.......................................    $  82     $   39    $   67     $   55       -      $   42    $   55    $   25
   10 years......................................    $ 179     $   87    $  148     $  122       -      $   93    $  122    $   57
</TABLE>

+   The Funds' investment adviser has undertaken to limit Total Fund Operating
    Expenses of each of the Funds through October 23, 1999 to the percentages
    shown above. There is no obligation to continue these waivers after that
    time. Absent such waivers and/or reimbursements, Management Fees for the
    Emerging Markets Fund, High Yield Fund, International Growth Fund, Municipal
    Bond Fund, Select Equity Fund, Global Income Fund, U.S. Equity Fund and U.S.
    Fixed Income Fund would equal 1.00%, .70%, .80%, .70% , .75%, .50%, .75% and
    .375%, respectively; Other Expenses would equal 1.01%, .44%, .42%, .69%,
    .73%, .67%, .43% and .365%, respectively; and Total Fund Operating Expenses
    would equal 2.01%, 1.14%, 1.22%, 1.39%, 1.48%, 1.17%, 1.18% and .74%,
    respectively. Other Expenses for the Funds are based on annualized estimates
    of expenses for the fiscal year ending August 31, 1999, net of any fee
    waivers or expense reimbursements.
                                 ---------------

        The expense table shows the costs and expenses that an investor will
bear directly or indirectly as an Institutional shareholder of each Fund.
Certain broker-dealers and financial institutions also may charge their clients
fees in connection with investments in a Fund's Institutional Shares, which fees
are not reflected in the table. The Example should not be considered a
representation of past or future expenses; actual Fund expenses may be greater
or less than those shown. Moreover, while the Example assumes a 5% annual
return, each Fund's actual performance will vary and may result in a return
greater or less than 5%.

INVESTMENT OBJECTIVES AND POLICIES
- --------------------------------------------------------------------------------

        The investment objective of each Fund may not be changed without the
affirmative vote of a majority of the Fund's outstanding shares (as defined in
the Investment Company Act of 1940, as amended (the "1940 Act")). As with other
mutual funds, there can be no assurance that any Fund will achieve its
investment objective. Because of their different investment emphases, each Fund
should be considered as a specialized investment portfolio and not as a balanced
investment program by itself. The Statement of Additional Information contains a
more detailed description of the various investments and investment techniques
used by the Funds.

        The investment objective of the Emerging Markets Fund is to provide
long-term appreciation of capital. The Fund seeks to achieve this objective by
investing primarily in equity securities of issuers in "Emerging Markets." As
used in this Prospectus, an Emerging Market is any country which is generally
considered to be an emerging or developing country by the World Bank and the
International Finance Corporation, as well as countries that are classified by
the United Nations as emerging or developing, at the time of the Fund's
investment. The countries that currently will not be considered Emerging Markets
include: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany,
Ireland, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway,
Portugal, Spain, Switzerland, the United Kingdom and the United States. Under
normal market conditions, the Fund will invest a minimum of 80% of its total
assets in equity securities of issuers in Emerging Markets. The Fund will not
necessarily seek to allocate investments on a geographical basis or on the basis
of the level of economic development of any particular country. The Fund will at
all times, except during temporary defensive periods, maintain investments in at
least three Emerging Market countries.
        The Fund normally will not select portfolio securities on the basis of
their dividend or income potential unless BEA or Credit Suisse Asset Management
Limited, sub-investment adviser to the Emerging Markets Fund ("CSAM" and
collectively with BEA, as applicable, the "Adviser"), believes the income will
contribute to the securities' capital appreciation potential.
        An equity security of an issuer in an Emerging Market is defined as
common stock and preferred stock (including convertible preferred stock); bonds,
notes and debentures convertible into common or preferred stock; stock purchase
warrants and rights; equity interests in trusts and partnerships; and depository
receipts of companies: (i) the principal securities trading market for which is
in an Emerging Market; (ii) whose principal trading market is in any country,
provided that, alone or on a consolidated basis, they derive 50% or more of
their annual revenue from either goods produced, sales made or services
performed in Emerging Markets; or (iii) that are organized under the laws of,
and with a principal office in, an Emerging Market. Determinations as to
eligibility will be made by BEA based on publicly available information and
inquiries made to the companies.

        To the extent that the Fund's assets are not invested as described
above, the remainder of the assets may be invested in government or corporate
debt securities of Emerging Market or developed countries, although the Fund
does not presently intend to invest more than 5% of its net assets in debt
securities. Debt securities, including convertible debt securities, may include
lower-rated or comparable unrated debt securities. See "Risk Factors and Special
Considerations -- Lower-Rated Securities."

HIGH YIELD FUND

        The investment objective of the High Yield Fund is to provide high total
return. The Fund seeks to achieve this objective by investing primarily in high
yield high risk fixed-income securities issued by corporations, governments and
agencies, both U.S. and foreign. Under normal market conditions, the Fund will
invest at least 65% of its total assets in such high yield fixed-income
securities. The Fund may also invest in fixed-income securities which may have
equity characteristics, such as convertible bonds and equity securities such as
warrants and options. The Fund is not limited in the extent to which it can
invest in securities rated below BBB, the fourth highest bond rating of Standard
& Poor's Rating Services ("S&P"), or in comparable unrated securities.
(Securities rated BBB or better by S&P are commonly referred to as "investment
grade.") See "Risk Factors and Special Considerations -- Lower-Rated
Securities." The portion of the Fund's assets invested in various countries will
vary from time to time depending on the assessment of market opportunities by
BEA.



                                      -10-
<PAGE>   12

        The value of the securities held by the Fund and thus the net asset
value of the Fund, generally will vary inversely in relation to changes in
prevailing interest rates. Also, the value of such securities may be affected by
changes in real or perceived creditworthiness of the issuers. The Fund may
purchase debt securities of any maturity, and the average maturity of the Fund's
assets will vary based upon BEA's assessment of economic and market conditions.

INTERNATIONAL GROWTH FUND

        The International Growth Fund's investment objective is to provide
long-term appreciation of capital. The Fund will pursue its objective by
investing primarily in equity securities of non-U.S. issuers. The Fund defines
equity securities of non-U.S. issuers as securities of issuers whose principal
activities are outside the United States. The Fund expects that its investments
will be concentrated in, but not limited to, Argentina, Australia, Austria,
Brazil, Canada, Chile, Columbia, Denmark, Finland, France, Germany, Greece,
Hungary, Israel, Italy, Japan, Malaysia, Mexico, the Netherlands, New Zealand,
Norway, Portugal, Singapore, South Africa, South Korea, Spain, Sweden,
Switzerland, Thailand, the United Kingdom and Venezuela. The Fund may invest in
securities of issuers in Emerging Markets, as defined above under "Investment
Objectives and Policies -- Emerging Markets Fund," but does not expect to invest
more than 40% of its total assets (at the time of purchase) in securities of
issuers in Emerging Markets. The Fund will invest in securities of issuers from
at least three countries outside the United States.

        Under normal market conditions, the Fund will invest a minimum of 80% of
its total assets in equity securities of non-U.S. issuers. Such equity
securities may include common stock and preferred stock (including convertible
preferred stock); bonds, notes and debentures convertible into common or
preferred stock; stock purchase warrants and rights; equity interests in trusts
and partnerships; and depository receipts of companies. In choosing investments,
the Adviser looks for companies that present attractive opportunities for
capital growth.

        The Fund may invest up to 20% of its total assets in debt securities
issued by U.S. or foreign governments or corporations, although it does not
currently intend to invest more than 5% of its net assets in debt securities.
The Fund has no limitation on the maturity or the credit quality of the debt
securities in which it invests, which may include lower-rated or comparable
unrated debt securities. See "Risk Factors and Special Considerations -- 
Lower-Rated Securities."

MUNICIPAL BOND FUND

        The investment objective of the Municipal Bond Fund is to provide high
total return. The Fund seeks to achieve this objective by investing at least 80%
of its total assets in fixed-income securities issued by state and local
governments ("Municipal Obligations"), although the Fund may invest its assets
without limitation in securities of below investment-grade quality. See "Risk
Factors and Special Considerations -- Lower-Rated Securities." The Fund may
invest up to 40% of its assets (at the time of purchase) in municipal
obligations the interest on which constitutes an item of tax preference for
purposes of the federal alternative minimum tax ("Alternative Minimum Tax
Securities").

        The two principal classifications of Municipal Obligations are "general
obligation" securities and "revenue" securities. General obligation securities
are secured by the issuer's pledge of its full faith, credit and taxing power
for the payment of principal and interest. Revenue securities are payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special excise tax or other specific
revenue source such as the user of the facility being financed. Revenue
securities include private activity bonds which are not payable from the
unrestricted revenues of the issuer. Consequently, the credit quality of private
activity bonds is usually directly related to the credit standing of the
corporate user of the facility involved. Municipal Obligations may also include
"moral obligation" bonds, which are normally issued by special purpose public
authorities. If the issuer of moral obligation bonds is unable to meet its debt
service obligations from current revenues, it may draw on a reserve fund, the
restoration of which is a moral commitment but not a legal obligation of the
state or municipality which created the issuer.

        Eligible Municipal Obligations include debt obligations issued by
governmental entities to obtain funds for various public purposes, including the
construction of a wide range of public facilities, the refunding of outstanding
obligations, the payment of general operating expenses and the extension of
loans to public institutions and facilities. Private activity bonds issued by or
on behalf of public authorities to finance various privately operated facilities
are considered Municipal Obligations.



                                      -11-
<PAGE>   13

        Also included within the general category of Municipal Obligations are
participation certificates in a lease, an installment purchase contract, or a
conditional sales contract ("lease obligations") entered into by a state or
political subdivision to finance the acquisition or construction of equipment,
land, or facilities. Although lease obligations do not constitute general
obligations of the issuer for which the lessee's unlimited taxing power is
pledged, certain lease obligations are backed by the lessee's covenant to
appropriate money to make the lease obligation payments. However, under certain
lease obligations, the lessee has no obligation to make these payments in future
years unless money is appropriated on a yearly basis. Although
"non-appropriation" lease obligations are secured by the leased property,
disposition of the property in the event of foreclosure might prove difficult.
These securities represent a relatively new type of financing that is not yet as
marketable as more conventional securities. Moreover, certain investments in
lease obligations may be illiquid and subject to the investment limitations
described in the Statement of Additional Information under "Common Investment
Policies -- All Funds -- Illiquid Securities."

SELECT EQUITY FUND

      The investment objective of the Select Equity Fund is to seek long-term
appreciation of capital. The Fund seeks to achieve its investment objective by
investing primarily in U.S. equity securities that the Adviser believes are
undervalued. The Adviser will apply its Select Equity analysis in assembling and
managing the Fund's portfolio. In the selection of industry sectors to
emphasize, the Adviser searches for sectors with favorable economic profit
trends. Within this framework, the Adviser will select specific securities by
emphasizing, in addition to traditional analyses such as price/earnings ratios,
the economic profit of a company measured by its cash flow relative to its
capital assets. The Fund normally will not emphasize dividend income in choosing
securities, unless BEA believes the income will contribute to the securities'
appreciation potential.

      Under normal market conditions, the Fund will invest at least 65% of its
total assets in U.S. equity securities. Equity securities include common stocks,
preferred stocks, convertible securities, and other securities, such as rights
and warrants, which derive their values from common stocks. The Fund may also
invest in fixed income securities and in money market instruments. The Fund may
purchase lower-rated or comparable unrated convertible securities and fixed
income securities.

        The Fund may invest without limit in foreign securities, principally
through the purchase of dollar-denominated ADRs of foreign issuers, and engage
in foreign currency transactions. See below, and "Risk Factors and Special
Considerations -- Foreign Securities" and "-- Foreign Currency Transactions."
The Fund may also purchase lower-rated debt securities. See "Risk Factors and
Special Considerations -- Lower-Rated Securities."

GLOBAL INCOME FUND

        The investment objective of the Global Income Fund is to provide high
total return. The Fund seeks to achieve this objective by investing at least 65%
of its total assets in fixed income securities issued by foreign and domestic
corporations, governments and agencies. Under normal market conditions, the Fund
will seek to maintain an average weighted quality not lower BBB, the fourth
highest bond rating of S&P, or in comparable unrated securities. (Securities
rated BBB or better by S&P are commonly referred to as "investment grade."). The
Fund may invest in fixed-income securities which may have equity
characteristics, such as convertible bonds. The Fund will not limit its
investments in securities rated below investment grade by recognized rating
agencies or in comparable unrated securities. The Fund's investments in fixed
income securities may include securities rated D by S&P, which are in default.
See "APPENDIX" for further information concerning the ratings of Moody's and S&P
and their significance. The portion of the Fund's assets invested in various
countries will vary from time to time depending the assessment of market
opportunities by BEA or CSAM, the Fund's sub-investment adviser. There is no
limit on investments in any region, country or currency, although the Fund will
normally invest in at least three different countries. See "Risk Factors and
Special Considerations -- Lower-Rated Securities."

        In addition to fixed income securities issued by foreign and domestic
corporations, the Fund may also invest in foreign government securities
("sovereign bonds"), U.S. Government securities including government agencies'
securities, debt obligations of supranational entities, Brady Bonds, loan
participations and assignments, convertible securities, mortgage-backed
securities, asset-backed securities, zero-coupon securities, when-issued
securities, repurchase and reverse repurchase agreements and dollar rolls.

U.S. EQUITY FUND

      The investment objective of the U.S. Equity Fund is to provide long-term
appreciation of capital. The Fund seeks to achieve this objective by investing,
under normal market conditions, at least 65% of its total assets in U.S. equity
securities. Equity securities include common stocks, preferred stocks, and
securities which are convertible into common stock and readily marketable
securities, such as rights and warrants, which derive their value from common
stock. The Fund may also invest up to 35% of its assets in dollar-denominated
ADRs of foreign issuers and similar securities and in lower-rated or comparable
unrated convertible securities. For defensive purposes, the Fund may invest up
to 35% of its total assets in fixed income securities. The Fund normally will
not emphasize dividend or interest income in choosing securities, unless BEA
believes the income will contribute to the securities' appreciation potential.
See "Risk Factors and Special Considerations -- Lower-Rated Securities."

U.S. FIXED INCOME FUND

      The investment objective of the U.S. Fixed Income Fund is to provide high
total return. The Fund seeks to achieve this objective by investing, under
normal market conditions, at least 65% of its total assets in domestic fixed
income securities. Debt securities may include, without limitation, bonds,
debentures, notes, equipment lease and trust certificates, mortgage-related
securities of corporate issuers, and obligations issued or guaranteed by the
U.S. Government or its agencies or instrumentalities. The Fund may invest up to
35% of its total assets in debt securities of foreign issuers, including
emerging market debt. With respect to 35% of the Fund's total assets, the Fund
may also invest in other securities, including, but not limited to, equity
securities such as preferred stock and equity-related securities. Under normal
market conditions, the Fund will seek to maintain an average dollar-weighted
credit rating comparable to the AA rating of S&P. Subject to this condition,
however, the Fund may invest in lower-rated debt securities. See "Risk Factors
and Special Considerations -- Lower-Rated Securities" below. The Adviser
estimates that the average weighted maturity of the Fund will range between 5
and 15 years.

      Depending on prevailing market conditions, the Fund may purchase debt
securities at a discount from face value, which produces a yield greater than
the coupon rate. Conversely, if debt securities are purchased at a premium over
face value, the yield will be lower than the coupon rate. An increase in
interest rates will generally reduce the value of the fixed income investments
in the Fund and a decline in interest rates will generally increase the value of
those investments. Also, the value of such securities may be affected by changes
in real or perceived creditworthiness of the issuers.

PORTFOLIO INVESTMENTS

      TEMPORARY INVESTMENTS. To the extent permitted by its investment
objective and policies, each of the Funds may hold cash or cash equivalents
pending investment or to meet redemption requests. In addition, for defensive
purposes due to abnormal market or economic situations, as determined by the
Fund's Adviser, each Fund may reduce its holdings in other securities and invest
up to 100% of its assets in cash or certain short-term (less than twelve months
to maturity) and medium-term (not greater than five years to maturity)
interest-bearing instruments or deposits of United States and foreign issuers.
Such investments may include, but are not limited to, commercial paper,
certificates of deposit, variable or floating rate notes, bankers' acceptances,
time deposits, government securities and money market deposit accounts. See
Statement of Additional Information, "Common Investment Policies -- Temporary
Investments." To the extent a Fund invests in temporary investments, the Fund
may not achieve its investment objective.

      RULE 144A SECURITIES. Rule 144A Securities (as defined below) are
securities which are restricted as to resale to the general public, but which
may be resold to "qualified institutional buyers." Each Fund may invest in Rule
144A Securities that the Fund's Adviser has determined are liquid pursuant to
guidelines established by the Fund's Board of Directors.

      BORROWING. Each Fund may borrow up to 33-1/3 percent of its total assets
without obtaining shareholder approval. The Funds intend to borrow or to engage 
in reverse repurchase agreements or dollar roll transactions only for temporary 
or emergency purposes. See Statement of Additional Information, "Common 
Investment Policies -- All Funds -- Reverse Repurchase Agreements" and 
"-- Borrowing."



                                      -13-
<PAGE>   15

        LENDING OF PORTFOLIO SECURITIES. Each Fund may also lend its portfolio
securities to financial institutions against collateral consisting of cash, U.S.
Government securities or irrevocable bank letters of credit, which are equal at
all times to at least 102% of the value of the securities loaned (105% in the
case of foreign securities loaned). Such loans would involve risks of delay in
receiving additional collateral in the event the value of the collateral
decreased below the value of the securities loaned or of delay in recovering the
securities loaned or even loss of rights in the collateral should the borrower
of the securities fail financially. However, loans will be made only to
borrowers deemed by the Fund's Adviser to be of good standing and only when, in
the Adviser's judgment, the income to be earned from the loans justifies the
attendant risks. Any loans of a Fund's securities will be fully collateralized
and marked to market daily. A Fund may not make loans in excess of 50% of its
total assets immediately before such loans.

        INVESTMENT COMPANIES. Each Fund may invest in securities issued by other
investment companies to the extent permitted by the 1940 Act. As a shareholder
of another investment company, each Fund would bear, along with other
shareholders, its pro rata portion of the other investment company's expenses,
including advisory fees. These expenses would be in addition to the advisory and
other expenses that a Fund bears directly in connection with its own operations.

        U.S. GOVERNMENT SECURITIES. The obligations issued or guaranteed by the
U.S. government in which each Fund may invest include direct obligations of the
U.S. Treasury and obligations issued by U.S. government agencies and
instrumentalities. Included among direct obligations of the United States are
Treasury Bills, Treasury Notes and Treasury Bonds, which differ principally in
terms of their maturities. Treasury Bills have maturities of less than one year,
Treasury Notes have maturities of one to 10 years and Treasury Bonds generally
have maturities of greater than 10 years at the date of issuance. Included among
the obligations issued by agencies and instrumentalities of the United States
are: instruments that are supported by the full faith and credit of the United
States (such as certificates issued by the Government National Mortgage
Association ("GNMA")); instruments that are supported by the right of the issuer
to borrow from the U.S. Treasury (such as securities of Federal Home Loan
Banks); and instruments that are supported by the credit of the instrumentality
(such as Federal National Mortgage Association ("FNMA") and Federal Home Loan
Mortgage Corporation ("FHLMC") bonds).

RISK FACTORS AND SPECIAL CONSIDERATIONS

        For certain additional risks related to each Fund's investments, see
"Portfolio Investments" and "Certain Investment Strategies."

        GENERAL. Among the factors that may be considered in deciding whether to
invest in a security are the issuer's financial resources, its sensitivity to
economic conditions and trends, its operating history and the ability of the
issuer's management. Bond prices generally vary inversely in relation to changes
in the level of interest rates, as well as in response to other market factors
and changes in the creditworthiness of the issuers of the securities. U.S.
Government securities are considered to be of the highest credit quality
available. U.S. Government securities, however, will be affected by general
changes in interest rates. The price volatility of a Fund's shares where the
Fund invests in intermediate maturity bonds will be substantially less than that
of long-term bonds. An intermediate maturity bond will generally have a lower
yield than that of a long-term bond. Longer-term securities in which the Funds
may invest generally offer a higher current yield than is offered by
shorter-term securities, but also generally involve greater volatility of price
and risk of capital than shorter-term securities.

        FOREIGN SECURITIES. Investing in the securities of non-U.S. issuers
involves opportunities and risks that are different from investing in the
securities of U.S. issuers. The risks associated with investing in securities of
non-U.S. issuers are generally heightened for investments in securities of
issuers in emerging markets.

        Because foreign securities generally are denominated and pay dividends
or interest in foreign currencies, and the Funds may hold from time to time
various foreign currencies pending their investment in foreign securities or
their conversion into U.S. dollars, the value of the Funds' assets as measured
in U.S. dollars may be affected favorably or unfavorably by changes in exchange
rates. In addition, investors should realize that the value of the Funds'
investments may be adversely affected by changes in political or social
conditions, diplomatic relations, confiscatory taxation, expropriation,
limitation on the removal of funds or assets, or imposition of (or change in)
exchange control regulations in those foreign nations. In addition, changes in
government administrations or economic or monetary policies in the U.S. or
abroad could result in appreciation or depreciation of portfolio securities and
could favorably or adversely affect the Funds' operations. Furthermore, the
economies of individual 


                                      -14-
<PAGE>   16

foreign nations may differ from that of the United States, whether favorably or
unfavorably, in areas such as growth of gross national product, rate of
inflation, capital reinvestment, resource self-sufficiency and balance of
payments position. Any foreign investments made by the Funds must be made in
compliance with U.S. and foreign currency restrictions and tax laws restricting
the amounts and types of foreign investments.

        In general, less information is publicly available with respect to
certain foreign issuers than is available with respect to U.S. companies. Most
foreign companies are also not subject to the uniform accounting and financial
reporting requirements applicable to issuers in the United States. The Funds'
foreign investments may be less liquid and their prices may be more volatile
than comparable investments in securities in U.S. companies. Expenses relating
to foreign investments are generally higher than those relating to domestic
securities. In addition, there is generally less government supervision and
regulation of securities exchanges, brokers and issuers in foreign countries
than in the United States.

        DEPOSITARY RECEIPTS. Certain of the above risks may be involved with
American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs") and
International Depositary Receipts ("IDRs"), instruments that evidence ownership
in underlying securities issued by a foreign corporation. ADRs, EDRs and IDRs
may not necessarily be denominated in the same currency as the securities whose
ownership they represent. ADRs are typically issued by a U.S. bank or trust
company. EDRs (sometimes referred to as Continental Depositary Receipts) are
issued in Europe, and IDRs (sometimes referred to as Global Depositary Receipts)
are issued outside the United States, each typically by non-U.S. banks and trust
companies.

        FOREIGN CURRENCY TRANSACTIONS. The over the counter market in forward
foreign currency exchange contracts offers less protection against defaults by
the other party to such instruments than is available for currency instruments
traded on an exchange. Such contracts are subject to the risk that the
counterparty to the contract will default on its obligations. Since these
contracts are not guaranteed by an exchange or clearinghouse, a default on the
contract would deprive a Fund of unrealized profits, transaction costs or the
benefits of a currency hedge or force a Fund to cover its purchase or sale
commitments, if any, at the current market price. A Fund will not enter into
forward foreign currency exchange contracts unless the credit quality of the
unsecured senior debt or the claims-paying ability of the counterparty is
considered to be investment grade by the Fund's Adviser.

        Currency exchange rates may fluctuate significantly over short periods
of time. They generally are determined by the forces of supply and demand in the
foreign exchange markets and the relative merits of investments in different
countries, actual or perceived changes in interest rates and other complex
factors as seen from an international perspective. Currency exchange rates also
can be affected unpredictably by intervention by U.S. or foreign governments or
central banks, or the failure to intervene, or by currency controls or political
developments in the United States or abroad. The foreign currency market offers
less protection against defaults in the forward trading of currencies than is
available when trading in currencies occurs on an exchange. Since a forward
currency contract is not guaranteed by an exchange or clearinghouse, a default
on the contract would deprive a Fund of unrealized profits or force such Fund to
cover its commitments for purchase or resale, if any, at the current market
price.

        EMERGING MARKETS. (Emerging Markets Fund, Global Telecommunications
Fund, International Growth Fund and U.S. Fixed Income Fund only) Investing in
securities of issuers located in emerging markets involves not only the risks
described below with respect to investing in foreign securities, but also other
risks, including exposure to economic structures that are generally less diverse
and mature than, and to political systems that can be expected to have less
stability than, those of developed countries. For example, many investments in
emerging markets experienced significant declines in value due to political and
currency volatility in emerging market countries during the latter part of 1997.
Other characteristics of emerging markets that may affect investment there
include certain national policies that may restrict investment by foreigners in
issuers or industries deemed sensitive to relevant national interests and the
absence of developed legal structures governing private and foreign investments
and private property. The typically small size of the markets for securities of
issuers located in emerging markets and the possibility of a low or nonexistent
volume of trading in those securities may also result in a lack of liquidity and
in price volatility of those securities.

        LOWER-RATED SECURITIES. The widespread expansion of government, consumer
and corporate debt within the economy has made the corporate sector, especially
cyclically sensitive industries, more vulnerable to economic downturns or
increased interest rates. Because lower-rated debt securities involve issuers
with weaker credit fundamentals (such as debt-to-equity ratios, interest 



                                      -15-
<PAGE>   17

charge coverage, earnings history and the like), an economic downturn, or
increases in interest rates, could severely disrupt the market for lower-rated
debt securities and adversely affect the value of outstanding debt securities
and the ability of the issuers to repay principal and interest.

        Lower-rated debt securities (commonly known as "junk bonds") possess
speculative characteristics and are subject to greater market fluctuations and
risk of lost income and principal than higher-rated debt securities for a
variety of reasons. The markets for and prices of lower-rated debt securities
have been found to be less sensitive to interest rate changes than higher-rated
investments, but more sensitive to adverse economic changes or individual
corporate developments. Also, during an economic downturn or substantial period
of rising interest rates, highly leveraged issuers may experience financial
stress which would adversely affect their ability to service their principal and
interest payment obligations, to meet projected business goals and to obtain
additional financing. If the issuer of a debt security owned by a Fund
defaulted, the Fund could incur additional expenses in seeking recovery with no
guaranty of recovery. In addition, periods of economic uncertainty and changes
can be expected to result in increased volatility of market prices of
lower-rated debt securities and a Fund's net asset value. Lower-rated debt
securities also present risks based on payment expectations. For example,
lower-rated debt securities may contain redemption or call provisions. If an
issuer exercises these provisions in a declining interest rate market, a Fund
would have to replace the security with a lower yielding security, resulting in
a decreased return for investors. Conversely, a lower-rated debt security's
value will decrease in a rising interest rate market, as will the value of a
Fund's assets. If a Fund experiences unexpected net redemptions, this may force
it to sell its lower-rated debt securities, without regard to their investment
merits, thereby decreasing the asset base upon which a Fund's expenses can be
spread and possibly reducing a Fund's rate of return.

        In addition, to the extent that there is no established retail secondary
market, there may be thin trading of lower-rated debt securities, and this may
have an impact on the ability of the Fund's Adviser to both value accurately
lower-rated debt securities and the Fund's assets, and to dispose of the debt
securities. Adverse publicity and investor perceptions, whether or not based on
fundamental analysis, may decrease the value and liquidity of lower-rated debt
securities, especially in a thinly traded market.

        FIXED INCOME SECURITIES. The value of the fixed income securities held
by a Fund, and thus the net asset value of the shares of a Fund, generally will
vary inversely in relation to changes in prevailing interest rates. Thus, if
interest rates have increased from the time a debt or other fixed income
security was purchased, such security, if sold, might be sold at a price less
than its cost. Conversely, if interest rates have declined from the time such a
security was purchased, such security, if sold, might be sold at a price greater
than its cost. Also, the value of such securities may be affected by changes in
real or perceived creditworthiness of the issuers. Thus, if creditworthiness is
enhanced, the price may rise. Conversely, if creditworthiness declines, the
price may decline. A Fund is not restricted to any maximum or minimum time to
maturity in purchasing portfolio securities, and the average maturity of the
Fund's assets will vary based upon the Adviser's assessment of economic and
market conditions.

        NON-PUBLICLY TRADED SECURITIES; RULE 144A SECURITIES. Each Fund may
purchase securities that are not registered under the Securities Act of 1933, as
amended (the "Securities Act"), but that can be sold to "qualified institutional
buyers" in accordance with Rule 144A under the Securities Act ("Rule 144A
Securities"). A Rule 144A Security will be considered illiquid and therefore
subject to each Fund's limitation on the purchase of illiquid securities, unless
the Fund's Board determines on an ongoing basis that an adequate trading market
exists for the security. In addition to an adequate trading market, the Board
will also consider factors such as trading activity, availability of reliable
price information and other relevant information in determining whether a Rule
144A Security is liquid. This investment practice could have the effect of
increasing the level of illiquidity in the Funds to the extent that qualified
institutional buyers become uninterested for a time in purchasing Rule 144A
Securities. The Board of each Fund will carefully monitor any investments by the
Fund in Rule 144A Securities. The Boards may adopt guidelines and delegate to
the relevant Fund's Adviser the daily function of determining and monitoring the
liquidity of Rule 144A Securities, although each Board will retain ultimate
responsibility for any determination regarding liquidity.

        Non-publicly traded securities (including Rule 144A Securities) may
involve a high degree of business and financial risk and may result in
substantial losses. These securities may be less liquid than publicly traded
securities, and a Fund may take longer to liquidate these positions than would
be the case for publicly traded securities. Although these securities may be
resold in privately negotiated transactions, the price realized from these sales
could be less than those originally paid by the Fund. Further, companies whose
securities are not publicly traded may not be subject to the disclosure and
other investor protection requirements that would be applicable if their
securities were publicly traded. A Fund's investment in illiquid securities is



                                      -16-
<PAGE>   18

subject to the risk that should the Fund desire to sell any of these securities
when a ready buyer is not available at a price that is deemed to be
representative of their value, the value of the Fund's net assets could be
adversely affected.

      NON-DIVERSIFIED STATUS. Each Fund is classified as a non-diversified
investment company under the 1940 Act, which means that each Fund is not limited
by the 1940 Act in the proportion of its assets that it may invest in the
obligations of a single issuer. Each Fund will, however, comply with
diversification requirements imposed by the Internal Revenue Code of 1986, as
amended (the "Code"), for qualification as a regulated investment company. As a
non-diversified investment company, each Fund may invest a greater proportion of
its assets in the obligations of a small number of issuers and, as a result, may
be subject to greater risk with respect to portfolio securities. To the extent
that a Fund assumes large positions in the securities of a small number of
issuers, its return may fluctuate to a greater extent than that of a diversified
company as a result of changes in the financial condition or in the market's
assessment of the issuers.

      EMERGING GROWTH AND SMALLER CAPITALIZATION COMPANIES; UNSEASONED ISSUERS.
Investing in securities of companies with continuous operations of less than
three years ("unseasoned issuers") may involve greater risks since these
securities may have limited marketability and, thus, may be more volatile than
securities of larger, more established companies or the market in general.
Because such companies normally have fewer shares outstanding than larger
companies, it may be more difficult for a Fund to buy or sell significant
amounts of such shares without an unfavorable impact on prevailing prices. These
companies may have limited product lines, markets or financial resources and may
lack management depth. In addition, these companies are typically subject to a
greater degree of changes in earnings and business prospects than are larger,
more established companies. There is typically less publicly available
information concerning these companies than for larger, more established ones.
Although investing in securities of unseasoned issuers offers potential for
above-average returns if the companies are successful, the risk exists that the
companies will not succeed and the prices of the companies' shares could
significantly decline in value. Therefore, an investment in a Fund may involve a
greater degree of risk than an investment in other mutual funds that seek
capital appreciation by investing in more established, larger companies.

        YEAR 2000 COMPLIANCE. Many services provided to a Fund and their
shareholders by BEA, CSAM, Counsellors Securities Inc., the Funds' distributor
("Counsellors Securities"), certain of the latter's affiliates (collectively,
the "Service Providers"), and the Funds' other service providers rely on the
functioning of their respective computer systems. Many computer systems cannot
distinguish the year 2000 from the year 1900, with resulting potential
difficulty in performing various calculations (the "Year 2000 Issue"). The Year
2000 Issue could potentially have an adverse impact on the handling of security
trades, the payment of interest and dividends, pricing, account services and
other Fund operations.

        The Service Providers recognize the importance of the Year 2000 Issue
and are taking appropriate steps necessary in preparation for the year 2000. At
this time, there can be no assurance that these steps will be sufficient to
avoid any adverse impact on the Funds nor can there be any assurance that the
Year 2000 Issue will not have an adverse effect on the Funds' investments or on
global markets or economies, generally.

        The Service Providers anticipate that their systems and those of the
Funds' other service providers will be adapted in time for the year 2000. To
further this goal, the Service Providers have coordinated a plan to repair,
adapt or replace systems that are not year 2000 compliant, and are seeking to
obtain similar representations from the Funds' other major service providers.
The Service Providers will be monitoring the Year 2000 Issue in an effort to
ensure appropriate preparation.

        GENERAL. Investment methods described in this prospectus are among those
which the Funds have the power to utilize. Accordingly, reference to any
particular method or technique carries no implication that it will be utilized
or, if it is, that it will be successful.

PORTFOLIO TRANSACTIONS AND TURNOVER RATE

        A Fund will attempt to purchase securities with the intent of holding
them for investment but may purchase and sell portfolio securities whenever the
Fund's Adviser believes it to be in the best interests of the relevant Fund. The
Fund's Adviser will effect portfolio transactions in each Fund without regard to
holding periods if, in its judgment, such transactions are advisable in light of
general market, economic or financial conditions. Portfolio turnover may vary
greatly from year to year as well as within a particular year. It is not
possible to predict each Fund's portfolio turnover rate. However, it is
anticipated that, 



                                      -17-
<PAGE>   19

under normal market conditions, each Fund's annual turnover rate should not
exceed 100%. High portfolio turnover rates (100% or more) may result in higher
dealer mark-ups or underwriting commissions as well as other transaction costs,
including correspondingly higher brokerage commissions. In addition, short-term
gains realized from portfolio turnover may be taxable to shareholders as
ordinary income. See "Dividends, Distributions and Taxes -- Taxes" below and
Portfolio Transactions" in the Statement of Additional Information.

        All orders for transactions in securities or options on behalf of a Fund
are placed by the Fund's Adviser with broker-dealers that it selects, including
Counsellors Securities and affiliates of Credit Suisse Group ("Credit Suisse").
A Fund may utilize Counsellors Securities or affiliates of Credit Suisse in
connection with a purchase or sale of securities when the Fund's Adviser
believes that the charge for the transaction does not exceed usual and customary
levels and when doing so is consistent with guidelines adopted by the Board.

CERTAIN INVESTMENT STRATEGIES

STRATEGY AVAILABLE TO ALL FUNDS

        FOREIGN CURRENCY TRANSACTIONS. The Funds may also enter into contracts
to purchase and sell forward foreign currency exchange contracts to seek to
enhance total return. A forward foreign currency exchange contract is a
negotiated agreement to exchange currency at a future time at a rate or rates
that may be higher or lower than those available on a "spot" (or cash) basis. A
Fund may enter into these contracts for purposes of increasing exposure to a
foreign currency or to shift exposure to foreign currency fluctuations from one
country to another. To the extent that such contracts are entered into to
enhance total return, they are considered speculative. If a Fund enters into
such a contract for any purpose, the Fund will be required to maintain in a
segregated account cash or liquid assets in an amount equal to the value of the
Fund's total assets committed to the consummation of the contract. The Funds
will not invest more than 50% of their respective total assets in such contracts
for the purpose of enhancing total return. There is no limit on the amount of
assets that the Funds may invest in such transactions for hedging purposes.

STRATEGIES AVAILABLE TO ALL FUNDS -- EXCEPT THE MUNICIPAL BOND FUND

        MORTGAGE-RELATED PASS-THROUGHS AND DERIVATIVES. The Funds may invest in
mortgage-related securities. Purchasable mortgage-related securities are
represented by pools of mortgage loans assembled for sale to investors by
various governmental agencies such as the GNMA and government-related
organizations such as the FNMA and the FHLMC, as well as by private issuers such
as commercial investment banks, savings and loan institutions, mortgage bankers
and private mortgage insurance companies. As with other interest-bearing
securities, the prices of such securities are inversely affected by changes in
interest rates. However, though the value of a mortgage-related security may
decline when interest rates rise, the converse is not necessarily true because
in periods of declining interest rates mortgages underlying securities are prone
to prepayment. For this and other reasons, a mortgage-related security's stated
maturity may be shortened by an unscheduled prepayment on underlying mortgages
and, therefore, it is not possible to predict accurately the security's return
to these Funds. Prepayments involve the risk that funds received upon prepayment
may have to be reinvested at lower interest rates.

        Mortgage-related securities acquired by these Funds may include
collateralized mortgage obligations ("CMOs") issued by FNMA, FHLMC or other U.S.
Government agencies or instrumentalities, as well as by private issuers. These
securities may be considered mortgage derivatives. CMOs provide an investor with
a specified interest in the cash flow of a pool of underlying mortgages or other
mortgage-related securities.

        ASSET-BACKED SECURITIES. The Funds may purchase asset-backed securities,
which represent a participation in, or are secured by and payable from, a stream
of payments generated by particular assets, most often a pool of assets similar
to one another. Assets generating such payments will consist of such instruments
as motor vehicle installment purchase obligations, credit card receivables and
home equity loans.

        Asset-backed securities may involve certain risks arising primarily from
the nature of the underlying assets (i.e., credit card and automobile loan
receivables as opposed to real estate mortgages). For example, credit card
receivables are generally unsecured and may require the repossession of personal
property upon the default of the debtor which may be difficult or 



                                      -18-
<PAGE>   20

impracticable in some cases. Asset-backed securities are considered an industry
for industry concentration purposes, and the Funds will therefore not purchase
any asset-backed securities which would cause 25% or more of a Fund's total
assets at the time of purchase to be invested in asset-backed securities.

        CONVERTIBLE SECURITIES. A convertible security is a bond, debenture,
note, preferred stock or other security that may be converted into or exchanged
for a prescribed 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 paid or accrued on debt or the
dividend paid on preferred stock until the convertible security matures or is
redeemed, converted or exchanged. Before conversion, convertible securities have
characteristics similar to nonconvertible debt securities in that they
ordinarily provide a stable stream of income with generally higher yields than
those of common stocks of the same or similar issuers. The Funds will invest in
convertible securities without regard to their credit ratings. See "Risk Factors
and Special Considerations -- Lower-Rated Securities".

STRATEGIES AVAILABLE TO THE MUNICIPAL BOND FUND

        TAX-EXEMPT DERIVATIVES AND OTHER MUNICIPAL OBLIGATIONS. The Fund may
invest in tax-exempt derivative securities relating to Municipal Obligations,
including tender option bonds, participations, beneficial interests in trusts
and partnership interests. A typical tax-exempt derivative security involves the
purchase of an interest in a pool of Municipal Obligations which interest
includes a tender option, demand or other feature allowing the Fund to tender
the underlying Municipal Obligation to a third party at periodic intervals and
to receive the principal amount thereof. A participation interest gives the Fund
an undivided interest in a Municipal Obligation in the proportion the Fund's
participation bears to the total principal amount of the Municipal Obligation,
and typically provides for a repurchase feature for all or any part of the full
principal amount of the participation interest, plus accrued interest. Trusts
and partnerships are typically used to convert long-term fixed rate high quality
bonds of a single state or municipal issuer into variable or floating rate
demand instruments.

        During normal market conditions, up to 20% of the Fund's net assets may
be invested in securities which are not Municipal Obligations; at least 80% of
the Fund's net assets will be invested in Municipal Obligations the interest on
which is exempt from regular federal income tax. During temporary defensive
periods, the Fund may invest without limitation in obligations which are not
Municipal Obligations and may hold without limitation uninvested cash reserves.
Such securities may include, without limitation, bonds, notes, variable rate
demand notes and commercial paper, provided such securities are rated within the
relevant categories, applicable to Municipal Obligations set forth above, or if
unrated, are of comparable quality as determined by the Adviser, and may also
include, without limitation, other debt obligations, such as bank obligations.
The Fund may acquire "stand-by commitments" with respect to Municipal
Obligations held by it. Under a stand-by commitment, a dealer agrees to purchase
at the Fund's option specified Municipal Obligations at a specified price. The
acquisition of a stand-by commitment may increase the cost, and thereby reduce
the yield, of the Municipal Obligation to which such commitment relates. The
Fund will acquire stand-by commitments solely to facilitate portfolio liquidity
and does not intend to exercise its rights thereunder for trading purposes.

        The amount of information regarding the financial condition of issuers
of Municipal Obligations may not be as extensive as that which is made available
by public corporations and the secondary market for Municipal Obligations may be
less liquid than that for taxable fixed-income securities. Accordingly, the
ability of the Fund to buy and sell tax-exempt securities may, at any particular
time and with respect to any particular securities, be limited.

        ALTERNATIVE MINIMUM TAX SECURITIES. The Fund may invest up to 40% of its
assets (at the time of purchase) in Alternative Minimum Tax Securities, which
are certain securities issued after August 7, 1986 to finance certain
non-governmental activities. While the income from Alternative Minimum Tax
Securities is exempt from regular federal income tax, it is a tax preference
item for purposes of the federal individual and corporate "alternative minimum
tax." The alternative minimum tax is a special tax that applies to a limited
number of taxpayers who have certain adjustments or tax preference items.
Available returns on Alternative Minimum Tax Securities acquired by the Fund may
be lower than those from other Municipal Obligations acquired by the Fund due to
the possibility of federal, state and local alternative minimum or minimum
income tax liability on Alternative Minimum Tax Securities.

INVESTMENT GUIDELINES

        Although there is no current intention of doing so in the coming year,
each Fund is authorized to (i) purchase securities on a when-issued basis and
purchase or sell securities for delayed delivery, (ii) purchase forward
commitments and (iii) (except in the case of the Municipal Bond Fund) purchase
stand-by commitments. Each Fund may invest up to 15% of its net assets in
securities with contractual or other restrictions on resale and other
instruments that are not readily marketable ("illiquid securities"), including
(i) securities issued as part of a privately negotiated transaction between an
issuer and one or more purchasers; (ii) repurchase agreements with maturities
greater than seven days; (iii) time deposits maturing in more than seven
calendar days; and (iv) certain Rule 144A Securities. Each Fund may borrow from
banks and enter into reverse repurchase agreements and dollar rolls for
temporary or emergency purposes, such as meeting redemption requests, provided
that reverse repurchase agreements and any other borrowing by the Fund may not
exceed 33-1/3% of total assets, and may pledge its assets to the extent
necessary to secure permitted borrowings. Whenever borrowings (including reverse
repurchase agreements, dollar rolls and borrowings from banks) exceed 5% of a
Fund's assets, the Fund will not make any investments (including roll-overs).
Except for the limitations on borrowing and the limitation on further
investments when borrowings exceed 5% of Fund assets, the investment guidelines
set forth in this paragraph may be changed at any time without shareholder
consent by vote of the Board of each Fund, subject to the limitations contained
in the 1940 Act. A complete list of investment restrictions that each Fund has
adopted identifying additional restrictions that cannot be changed without the
approval of the majority of the Fund's outstanding shares is contained in the
Statement of Additional Information under "Investment Limitations".

        Any investment policy or limitation which involves a maximum or minimum
percentage of securities shall not be considered to be violated unless an excess
over or a deficiency under the percentage occurs immediately after, and is
caused by, an acquisition or disposition of securities or utilization of assets
by a Fund.

have entered into an investment management agreement with BEA or its affiliates.
Shares may be purchased initially by completing the application and forwarding
the application to the address set forth above. Initial investments in any Fund
must be at least $3,000,000, except Shares may be purchased by existing clients
of BEA or its affiliates or by officers of such existing clients (or those
holding similar positions) with an initial investment of at least $100,000; all
subsequent investments for such persons must be at least $1,000. Subsequent
initial investments in any other Fund must be at least $100,000. In addition, a
Fund may, in its sole discretion, waive the initial and subsequent investment
minimum requirements with respect to investors who are employees of Warburg, BEA
or their affiliates or persons with whom Warburg has entered into an investment
advisory agreement. Existing investors will be given 15 days' notice by mail of
any increase in minimum investment requirements.

        After an investor has made his initial investment, additional shares may
be purchased at any time by mail or by wire in the manner outlined below. Wire
payments for initial and subsequent investments should be preceded by an order
placed with the Fund and should clearly indicate the investor's account number
and the name of the Fund in which shares are being purchased. 



                                      -23-

The Fund reserves the right to suspend the offering of shares for a period of
time or to reject any specific purchase order. In the interest of economy and
convenience, physical certificates representing shares in the Funds are not
normally issued.

        BY MAIL. If the investor desires to purchase Institutional Shares by
mail, a check or Federal Reserve Draft made payable to the Fund or BEA
Institutional Funds (in U.S. currency) should be sent along with the completed
account application to BEA Institutional Funds at an address set forth above.
Checks payable to the investor and endorsed to the order of the Fund or BEA
Institutional Funds will not be accepted as payment and will be returned to the
sender. If payment is received in proper form prior to the close of regular
trading on The New York Stock Exchange, Inc. (the "NYSE") (currently 4:00 p.m.,
Eastern time) on a day that the Fund calculates its net asset value (a "business
day"), the purchase will be made at the Fund's net asset value calculated at the
end of that day. If payment is received at or after the close of regular trading
on the NYSE, the purchase will be effected at the Fund's net asset value
determined for the next business day after payment has been received. Checks or
Federal Reserve Drafts that are not in proper form or that are not accompanied
or preceded by a complete account application will be returned to the sender.
Shares purchased by check or Federal Reserve Drafts are entitled to receive
dividends and distributions beginning on the day your purchase order is
executed. Checks or Federal Reserve Drafts in payment for shares of more than
one BEA Institutional Fund should be made payable to BEA Institutional Funds and
should be accompanied by a breakdown of amounts to be invested in each fund. If
a check used for purchase does not clear, the Fund will cancel the purchase and
the investor may be liable for losses or fees incurred. For a description of the
manner of calculating the Fund's net asset value, see "Net Asset Value" below.

        BY WIRE. Investors may also purchase Institutional Shares in a Fund
by wiring funds from their banks. Federal funds may be wired using the following
wire address:

                    State Street Bank and Trust Company
                    ABA# 0110 000 28
                    Attn.: Mutual Funds/Custody Department
                    BEA Institutional Funds
                    DDA# 9905-227-6
                    F/F/C: [Account # and Registration]

        If payment by wire is received prior to the close of regular trading on
the NYSE in proper form in accordance with instructions set forth above, the
shares will be priced according to the net asset value of the Fund on that day
and are entitled to dividends and distributions beginning on that day. However,
if a wire in proper form is received at or after the close of regular trading on
the NYSE, the payment will be held uninvested until the order is effected at the
close of business on the next business day. Payment for orders that are not
accepted will be returned to the prospective investor after prompt inquiry.

        PURCHASES IN-KIND. Subject to the approval of the Adviser, investors may
acquire shares of any of the Funds in exchange for portfolio securities that are
eligible for investment by the relevant Fund or Funds. Such portfolio securities
must (a) meet the investment objectives and policies of the Funds, (b) be
acquired for investment and not for resale, (c) be liquid securities which are
not restricted as to transfer either by law or liquidity of market, and (d) have
a value which is readily ascertainable. Generally an investor will recognize for
federal income tax purposes any gain or loss realized on an exchange of property
for shares. Under certain circumstances, initial investors may not recognize
gain or loss on such an exchange. Investors, particularly initial investors, are
urged to consult their tax advisers in determining the particular federal income
tax consequences of their purchase in-kind. Such exchanges will be subject to
each Fund's minimum investment requirement. Shareholders may be required to bear
certain administrative or custodial costs in effecting purchases in-kind.

        GENERAL. Each Fund reserves the right to reject any specific purchase
order, including certain purchases made by exchange (see "How to Redeem and
Exchange Shares -- Exchange of Shares" below). Purchase orders may be refused
if, in BEA's judgment, a Fund would be unable to invest the money effectively in
accordance with its investment objective and policies, or would otherwise
potentially be adversely affected. A Fund may discontinue sales of its shares if
management believes that a substantial further increase in assets may adversely
affect that Fund's ability to achieve its investment objective. In such event,
however, it is anticipated that existing shareholders would be permitted to
continue to authorize investment in such Fund and to reinvest any dividends or
capital gains distributions.

HOW TO REDEEM AND EXCHANGE SHARES

        REDEMPTION OF SHARES. An investor in a Fund may redeem (sell) his shares
on any day that the Fund's net asset value is calculated (see "Net Asset Value"
below).

        Institutional Shares of the Funds may be redeemed by mail. If an
investor desires to redeem his shares, a written request for redemption should
be sent to BEA Institutional Funds at an address indicated above under "How to
Open an Account." An investor should be sure that the redemption request
identifies the Fund, the number of shares to be redeemed and the investor's
account number. Payment of redemption proceeds may be delayed in connection with
account changes. Each mail redemption request must be signed by the registered
owner(s) (or his legal representative(s)) exactly as the shares are registered.

        After receipt of the redemption request by mail, the redemption proceeds
will, at the option of the investor, be paid by check and mailed to the investor
of record or be wired to the investor's bank as indicated in the account
application previously filled out by the investor. No Fund currently imposes a
service charge for effecting wire transfers but each Fund reserves the right to
do so in the future. Payment of redemption proceeds may be delayed for up to 15
days pending a determination that the check has cleared.

        If a redemption order is received by a Fund or its agent prior to the
close of regular trading on the NYSE, the redemption order will be effected at
the net asset value per share as determined on that day. If a redemption order
is received at or after the close of regular trading on the NYSE, the redemption
order will be effected at the net asset value as next determined. Except as
noted above, redemption proceeds will normally be mailed or wired to an investor
on the next business day following the date a redemption order is effected. If,
however, in the judgment of BEA, immediate payment would adversely affect a
Fund, each Fund reserves the right to pay the redemption proceeds within seven
days after the redemption order is effected. Furthermore, each Fund may suspend
the right of redemption or postpone the date of payment upon redemption (as well
as suspend or postpone the recordation of an exchange of shares) for such
periods as are permitted under the 1940 Act.

        The proceeds paid upon redemption may be more or less than the amount
invested depending upon a share's net asset value at the time of redemption. If
an investor redeems all the shares in his account, all dividends and
distributions declared up to and including the date of redemption are paid along
with the proceeds of the redemption.

        If, due to redemptions, the value of an investor's account drops to less
than $500, each Fund reserves the right to redeem the shares in that account at
net asset value. Prior to any redemption, the Fund will notify an investor in
writing that this account has a value of less than the minimum. The investor
will then have 30 days to make an additional investment before a redemption will
be processed by the Fund.

        REDEMPTION IN-KIND. The Funds reserve the right, at their discretion, to
honor any request for redemption of a Fund's shares by making payment in whole
or in part in securities chosen by the Fund and valued in the same way as they
would be valued for purposes of computing a Fund's net asset value. If payment
is made in securities, a shareholder may incur transaction costs in converting
these securities into cash after they have redeemed their shares. The Funds have
elected, however, to be governed by Rule 18f-1 under the 1940 Act so that a Fund
is obligated to redeem its shares solely in cash up to the lesser of $250,000 or
1% of its net asset value during any 90-day period for any one shareholder of a
Fund. Redeeming shareholders will be required to bear certain administrative or
custodial costs in effecting redemptions in-kind.

        EXCHANGE OF SHARES. An investor may exchange Institutional Shares of a
Fund for Institutional Shares of another Fund at their respective net asset
values. Exchanges may be effected in the manner described under "Redemption of
Shares" above. If an exchange request is received by BEA Institutional Funds or
its agent prior to the close of regular trading on the NYSE, the exchange will
be made at each fund's net asset value determined at the end of that business
day. Exchanges will be effected without a sales charge but must satisfy the
minimum dollar amount necessary for new purchases. A Fund may refuse exchange
purchases at any time without prior notice.

        The exchange privilege is available to shareholders residing in any
state in which the Institutional Shares being acquired may legally be sold. When
an investor effects an exchange of shares, the exchange is treated for federal
income tax purposes as a 



                                      -25-
<PAGE>   27
redemption. Therefore, the investor may realize a taxable gain or loss in
connection with the exchange. For further information regarding the exchange
privilege, an investor should contact BEA Institutional Funds at 800-401-2230.

        Each Fund reserves the right to refuse exchange purchases by any person
or group if, in the Adviser's judgment, the Fund would be unable to invest the
money effectively in accordance with its investment objective and policies, or
would otherwise potentially be adversely affected. Examples of when an exchange
purchase could be refused are when a Fund receives or anticipates receiving
large exchange orders at or about the same time and/or when a pattern of
exchanges within a short period of time (often associated with a "market timing"
strategy) is discerned. Each Fund reserves the right to terminate or modify the
exchange privilege at any time upon 60 days' notice to shareholders.

DIVIDENDS, DISTRIBUTIONS AND TAXES

        DIVIDENDS AND DISTRIBUTIONS. Each Fund calculates its dividends from net
investment income. Net investment income includes interest accrued and dividends
earned on the Fund's portfolio securities for the applicable period less
applicable expenses. Each of the Emerging Markets Fund, International Growth
Fund, Select Equity Fund and U.S. Equity Fund will distribute substantially all
of its net realized capital gains and all net investment income, if any, to its
shareholders annually. Each of the High Yield Fund, Global Income Fund and U.S.
Fixed income Fund will distribute substantially all of its net realized capital
gains, if any, to its shareholders annually and will distribute net investment
income at least quarterly. The Municipal Bond Fund will distribute substantially
all of its net realized capital gains, if any, annually and all net investment
income monthly. Net investment income earned on weekends and when the NYSE is
not open will be computed as of the next business day. Unless an investor
instructs a Fund to pay dividends or distributions in cash, dividends and
distributions will automatically be reinvested in additional Institutional
Shares of the relevant Fund at net asset value. The election to receive
dividends in cash may be made on the account application or, subsequently, by
writing to BEA Institutional Funds at an address set forth under "How to Open an
Account" or by calling BEA Institutional Funds at 800-401-2230.

        Special Distribution Matters Relating to the Municipal Bond Fund. If,
for any full fiscal year, the Municipal Bond Fund's total distributions exceed
net investment income and net realized capital gains, the excess distributions
may be treated as a taxable dividend or a tax-free return of capital (up to the
amount of the shareholder's tax basis in his shares). The amount treated as a
tax-free return of capital will reduce a shareholder's adjusted basis in his
shares. Pursuant to the requirements of the 1940 Act and other applicable laws,
a notice will accompany any distribution paid from sources other than net
investment income. In the event the Fund distributes amounts in excess of its
net investment income and net realized capital gains, such distributions may
have the effect of decreasing the Fund's total assets, which may increase the
Fund's expense ratio.

        A Fund may be required to withhold for U.S. federal income taxes 31% of
all distributions payable to shareholders who fail to provide the Fund with
their correct taxpayer identification number or to make required certifications,
or who have been notified by the U.S. Internal Revenue Service that they are
subject to backup withholding.

        TAXES. Each Fund intends to qualify each year as a "regulated investment
company" within the meaning of the Code. Each Fund, if it qualifies as a
regulated investment company, will be subject to a 4% non-deductible excise tax
measured with respect to certain undistributed amounts of ordinary income and
capital gain. Each Fund expects to pay such additional dividends and to make
such additional distributions as are necessary to avoid the application of this
tax.

        Investments in zero coupon securities may create special tax
consequences. Zero coupon securities do not make interest payments, although a
portion of the difference between a zero coupon security's maturity value and
its purchase price is imputed as income to the Funds each year even though the
Funds receive no cash distribution until maturity. Under the U.S. federal tax
laws applicable to mutual funds, the Funds will not be subject to tax on this
income if they pay dividends to their shareholders substantially equal to all
the income received from, or imputed with respect to, their investments during
the year, including their zero coupon securities. These dividends ordinarily
will constitute taxable income to the shareholders of the Funds.

        Dividends paid from net investment income and distributions derived from
net realized short-term capital gains are taxable to investors as ordinary
income whether received in cash or reinvested in additional Fund shares.
Distributions derived from net realized long-term capital gains will be taxable
to investors as long-term capital gains, regardless of how long investors have
held Fund shares or whether such distributions are received in cash or
reinvested in Fund shares. As a general rule, an investor's 



                                      -26-
<PAGE>   28

gain or loss on a sale or redemption of Fund shares will be a long-term capital
gain or loss if the investor has held the shares for more than one year and will
be a short-term capital gain or loss if the investor has held the shares for one
year or less. However, any loss realized upon the sale or redemption of shares
within six months from the date of their purchase will be treated as a long-term
capital loss to the extent of any amounts treated as distributions of long-term
capital gain during such six-month period with respect to such shares.

        Investors may be proportionately liable for taxes on income and gains of
the Funds, but investors not subject to tax on their income will not be required
to pay tax on amounts distributed to them. A Fund's investment activities,
including short sales of securities, will not result in unrelated business
taxable income to a tax-exempt investor. A Fund's dividends may qualify for the
dividends received deduction for corporations to the extent they are derived
from dividends attributable to certain types of stock issued by U.S. domestic
corporations.

        Dividends and interest received by the Funds may be subject to
withholding and other taxes imposed by foreign countries. However, tax
conventions between certain countries and the United States may reduce or
eliminate such taxes. If a Fund qualifies as a regulated investment company, if
certain asset and distribution requirements are satisfied and if more than 50%
of the Fund's total assets at the close of its fiscal year consists of stock or
securities of foreign corporations, the Fund may elect for U.S. income tax
purposes to treat foreign income taxes paid by it as paid by its shareholders. A
Fund may qualify for and make this election in some, but not necessarily all, of
its taxable years. If a Fund were to make an election, shareholders of the Fund
would be required to take into account an amount equal to their pro rata
portions of such foreign taxes in computing their taxable income and then treat
an amount equal to those foreign taxes as a U.S. federal income tax deduction or
as a foreign tax credit against their U.S. federal income taxes. Shortly after
any year for which it makes such an election, each Fund will report to its
shareholders the amount per share of such foreign income tax that must be
included in each shareholder's gross income and the amount which will be
available for the deduction or credit. No deduction for foreign taxes may be
claimed by a shareholder who does not itemize deductions.
Certain limitations will be imposed on the extent to which the credit (but not
the deduction) for foreign taxes may be claimed.

        Special Tax Matters Relating to the Municipal Bond Fund. As a regulated
investment company, the Municipal Bond Fund will designate and pay
exempt-interest dividends derived from interest earned on qualifying Municipal
Obligations. Such exempt-interest dividends may be excluded by investors of the
Fund from their gross income for federal income tax purposes although (i) all or
a portion of such exempt-interest dividends will be a specific tax-preference
item for purposes of the federal individual and corporate alternative minimum
taxes to the extent they are derived from certain types of private activity
bonds issued after August 7, 1996 and (ii) all exempt-interest dividends will be
a component of the "current earnings" adjustment item for purposes of the
federal corporate alternative minimum tax. Moreover, dividends paid by the Fund 
will be subject to a branch profits tax of up to 30% when received by certain 
foreign corporate investors.

        GENERAL. Statements as to the tax status of each investor's dividends
and distributions are mailed annually. Each investor will also receive, if
applicable, various written notices after the close of a Fund's prior taxable
year with respect to certain dividends and distributions which were received
from the Fund during the Fund's prior taxable year. Investors should consult
their own tax advisers with specific reference to their own tax situations,
including their state and local tax liabilities.

NET ASSET VALUE

        Each Fund's net asset value per share is calculated as of the close of
regular trading on the NYSE (currently 4:00 p.m., Eastern time) on each business
day, Monday through Friday, except on days when the NYSE is closed. The NYSE is
currently scheduled to be closed on New Year's Day, Dr. Martin Luther King, Jr.
Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day and Christmas Day, and on the preceding Friday or subsequent
Monday when one of these holidays falls on a Saturday or Sunday, respectively.
The net asset value per share of each Fund generally changes each day.

        The net asset value per Institutional Share of each Fund is computed by
adding the Institutional Shares' pro rata share of the value of the Fund's
assets, deducting the Institutional Shares' pro rata share of the Fund's
liabilities and the liabilities specifically allocated to Institutional Shares
and then dividing the result by the total number of outstanding Institutional
Shares.

      Securities listed on a U.S. securities exchange (including securities
traded through the Nasdaq National Market System) or foreign securities exchange
or traded in an over-the-counter market will be valued at the most recent sale
price when the valuation is made. Options and futures contracts will be valued
similarly. Debt obligations that mature in 60 days or less from the valuation
date are valued on the basis of amortized cost, unless the Board determines that
using this valuation method would not reflect the investments' value.
Securities, options and futures contracts for which market quotations are not
readily available and other assets will be valued at their fair value as
determined in good faith pursuant to consistently applied procedures established
by the Board. Further information regarding valuation policies is contained in
the Statement of Additional Information.

PERFORMANCE

        The Funds quote the performance of Institutional Shares separately from
Common Shares and Advisor Shares. The net asset value of Institutional Shares is
listed in The Wall Street Journal each business day under the heading "BEA
Institutional Funds." From time to time, each Fund may advertise yield and
average annual total return of its Institutional Shares over various periods of
time. The yield refers to net investment income generated by the Institutional
Shares over a specified thirty-day period, which is then annualized. That is,
the amount of net investment income generated by the Institutional Shares during
that thirty-day period is assumed to be generated over a 12-month period and is
shown as a percentage of the investment. In addition, advertisements concerning
the Municipal Bond Fund may describe a tax equivalent yield. The tax equivalent
yield demonstrates the yield on a taxable investment necessary to produce an
after-tax yield equal to the Institutional Shares' tax-free yield. It is
calculated by increasing the yield shown for the Institutional Shares to the
extent necessary to reflect the payment of specified tax rates. Thus, the tax
equivalent yield will always exceed a Fund's Institutional Shares' yield. Total
return figures show the average percentage change in value of an investment in
the Institutional Shares from the beginning of the measuring period to the end
of the measuring period. The figures reflect changes in the price of the
Institutional Shares assuming that any income dividends and/or capital gain
distributions made by a Fund during the period were reinvested in Institutional
Shares of the Fund. Total return will be shown for recent one-, five- and
ten-year periods, and may be shown for other periods as well (such as from
commencement of the Fund's operations or on a year-by-year, quarterly or current
year-to-date basis).

        When considering average total return figures for periods longer than
one year, it is important to note that the annual total return for one year in
the period might have been greater or less than the average for the entire
period. When considering total return figures for periods shorter than one year,
investors should bear in mind that each Fund seeks long-term appreciation and
that such return may not be representative of any Fund's return over a longer
market cycle. Each Fund may also advertise aggregate total return figures of its
Institutional Shares for various periods, representing the cumulative change in
value of an investment in the Institutional Shares for the specific period
(again reflecting changes in share prices and assuming reinvestment of dividends
and distributions). Aggregate and average total returns may be shown by means of
schedules, charts or graphs and may indicate various components of total return
(i.e., change in value of initial investment, income dividends and capital gain
distributions).

        Investors should note that yield, tax equivalent yield and total return
figures are based on historical earnings and are not intended to indicate future
performance. The Funds' Statements of Additional Information describes the
method used to 



                                      -28-
<PAGE>   30
determine the yield and total return. Current performance figures may be
obtained by calling BEA Institutional Funds at 800-401-2230.

        A Fund's total return or expense ratio may be compared with data
published by Lipper Analytical Services, Inc., CDA/Weisenberger Investment
Technologies, Inc., Mutual Fund Forecaster or Morningstar, Inc., or with the
performance of the Standard & Poor's 500 Stock Index, Standard & Poor's MidCap
400 Index, Moody's Bond Survey Bond Index, Wilshire 5000 Index, Lehman Brothers
Bond Indexes, Morgan Stanley Composite Index EAFE, Morgan Stanley Composite
Index-Free Emerging Markets, JP Morgan Global Government Bond Index (Unhedged),
First Boston High Yield Index, Consumer Price Index, Bond Buyer's 20-Bond Index,
Dow Jones Industrial Average, Salomon Smith Barney U.S. 1-Month Treasury Bill
Index(TM), national publications such as Money, Forbes, Barron's, The Wall
Street Journal or the New York Times or publications of a local or regional
nature, and other industry publications.

        In reports or other communications to investors or in advertising, each
Fund may also describe the general biography or work experience of the portfolio
managers of the Fund and may include quotations attributable to the portfolio
managers describing approaches taken in managing the Fund's investments,
research methodology underlying stock selection or the Fund's investment
objective. In addition, a Fund and its portfolio managers may render periodic
updates of Fund activity, which may include a discussion of significant
portfolio holdings; analysis of holdings by industry, country, credit quality
and other characteristics; and comparison and analysis of the Fund with respect
to relevant market and industry benchmarks. Each Fund may also discuss measures
of risk, the continuum of risk and return relating to different investments and
the potential impact of foreign stocks on a portfolio otherwise composed of
domestic securities.

GENERAL INFORMATION

        ORGANIZATION. On July 31, 1998, the Emerging Markets Fund, International
Growth Fund, High Yield Fund, Municipal Bond Fund, Global Income Fund, the
Select Equity Fund, U.S. Equity Fund and U.S. Fixed Income Fund were each
incorporated under the laws of the State of Maryland under the name "Warburg,
Pincus Emerging Markets II Fund, Inc.," "Warburg, Pincus International Growth
Fund, Inc.," "Warburg, Pincus High Yield Fund, Inc.," "Warburg, Pincus Municipal
Bond Fund, Inc.," "Warburg, Pincus Strategic Global Fixed Income Fund, Inc.,"
"Warburg, Pincus Select Economic Value Equity Fund, Inc.," "Warburg, Pincus U.S.
Core Equity Fund, Inc." and "Warburg, Pincus U.S. Core Fixed Income Fund, Inc.,"
respectively. Each Warburg Pincus Fund is an open-end mutual fund. On October
23, 1998, each Fund acquired all of the assets and liabilities of the
corresponding investment portfolio of the RBB Fund.

        Each Fund's charter authorizes its Board to issue three billion full and
fractional shares of capital stock, $.001 par value per share, of which one
billion shares are designated Common Shares, one billion shares are designated
Institutional Shares and one billion shares are designated Advisor Shares. Under
each Fund's charter documents, the Board has the power to classify or reclassify
any unissued shares of the Fund into one or more additional classes by setting
or changing in any one or more respects their relative rights, voting powers,
restrictions, limitations as to dividends, qualifications and terms and
conditions of redemption. A Board may similarly classify or reclassify any class
of its shares into one or more series and, without shareholder approval, may
increase the number of authorized shares of the Fund.

        MULTI-CLASS STRUCTURE. Each Fund currently offers another class of
shares, the Common Shares, pursuant to a separate prospectus. Individual
investors may purchase Common Shares and, if and when offered, individual
investors may only purchase Advisor Shares, through institutional shareholders
of record, broker-dealers, financial institutions, depository institutions,
retirement plans and financial intermediaries. Shares of each class represent
equal pro rata interests in the respective Fund and accrue dividends and
calculate net asset value and performance quotations in the same manner. Because
of the higher fees paid 


                                      -29-
<PAGE>   31
by Common Shares and Advisor Shares, the total return on Common Shares can be
expected to be lower than the total return on Institutional Shares and the total
return of Advisor Shares can be expected to be lower than the total return on
Common Shares and Institutional Shares. Investors may obtain information
concerning the Common Shares and, if and when offered, the Advisor Shares from
their investment professional or by calling Counsellors Securities at
800-369-2728. Unless the context clearly suggests otherwise, references to a
Fund in this Prospectus are to the Fund as a whole and not to any particular
class of the Fund's shares.

        VOTING RIGHTS. Investors in a Fund are entitled to one vote for each
full share held and fractional votes for fractional shares held. Shareholders of
a Fund will vote in the aggregate except where otherwise required by law and
except that each class will vote separately on certain matters pertaining to its
distribution and shareholder servicing arrangements. There will normally be no
meetings of investors for the purpose of electing members of the Board unless
and until such time as less than a majority of the members holding office have
been elected by investors. Any Director of a Fund may be removed from office
upon the vote of shareholders holding at least a majority of the relevant Fund's
outstanding shares, at a meeting called for that purpose. A meeting will be
called for the purpose of voting on the removal of a Board member at the written
request of holders of 10% of the outstanding shares of a Fund.

        SHAREHOLDER COMMUNICATIONS. Each investor will receive a quarterly
statement of his account, as well as a statement of his account after any
transaction that affects his share balance or share registration (other than the
reinvestment of dividends or distributions or investment made through the
Automatic Monthly Investment Plan). Each Fund will also send to its investors a
semiannual report and an audited annual report, each of which includes a list of
the investment securities held by the Fund and a statement of the performance of
the Fund. Periodic listings of the investment securities held by the Fund, as
well as certain statistical characteristics of the Fund, may be obtained by
calling BEA Institutional Funds at 800-401-2230 or on the BEA Institutional
Funds Web site at www.beafunds.com.

        The Institutional Share prospectuses of the Funds are combined in this
Prospectus. Each Fund offers only its own shares, yet it is possible that a Fund
might become liable for a misstatement, inaccuracy or omission in this
Prospectus with regard to another Fund.

                             DESCRIPTION OF RATINGS

Commercial Paper Ratings

        Commercial paper rated A-1 by Standard & Poor's Rating Services ("S&P")
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. Capacity for timely payment on commercial paper
rated A-2 is satisfactory, but the relative degree of safety is not as high as
for issues designated A-1.

        The rating Prime-1 is the highest commercial paper rating assigned by
Moody's Investors Service, Inc. ("Moody's"). Issuers rated Prime-1 (or related
supporting institutions) are considered to have a superior capacity for
repayment of short-term promissory obligations. Issuers rated Prime-2 (or
related supporting institutions) are considered to have a strong capacity for
repayment of short-term promissory obligations. This will normally be evidenced
by many of the characteristics of issuers rated Prime-1 but to a lesser degree.
Earnings trends and coverage ratios, while sound, will be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternative liquidity is maintained.

Corporate Bond Ratings

        The following summarizes the ratings used by S&P for corporate bonds:

        AAA - This is the highest rating assigned by S&P to a debt obligation
and indicates an extremely strong capacity to pay interest and repay principal.

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

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

        BBB - This is the lowest investment grade. Debt rated BBB has an
adequate capacity to pay interest and repay principal. Although 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 bonds in this category than for bonds in higher rated
categories.

        BB, B, CCC, CC, C - Debt rated BB, B, CCC, CC and C is regarded, on
balance, as predominately speculative with respect to capacity to pay interest
and repay principal in accordance with the terms of the obligation. BB
represents a lower degree of speculation than B and C the highest degree of
speculation. While such bonds will likely have some quality and protective
characteristics, these are outweighed by large uncertainties or major risk
exposures to adverse conditions.

        BB - Debt rated BB has less near-term vulnerability to default than
other speculative issues. However, they face 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.

        B - Debt rated B has a greater vulnerability to default but currently
have 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 



                                      A-1
<PAGE>   34

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 - This rating is typically applied to debt subordinated to senior
debt that is assigned an actual or implied CCC rating.

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

        Additionally, the rating CI is reserved for income bonds on which no
interest is being paid. Such debt is rated between debt rated C and debt rated
D.

        To provide more detailed indications of credit quality, the ratings from
"AA" to "CCC" may be modified by the addition of a plus or minus sign to show
relative standing within this major rating category.

        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. The D rating also will be used
upon the filing of a bankruptcy petition if debt service payments are
jeopardized.

        The following summarizes the ratings used by Moody's for corporate
bonds:

        Aaa - Bonds that 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 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 that 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 Igreater amplitude or there may be other elements present
which make the long-term risks 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 sometime 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 desirable
investments. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.

        Moody's applies numerical modifiers (1, 2 and 3) with respect to the
bonds rated "Aa" through "B". The modifier 1 indicates that the bond being rated
ranks in the higher end of its generic rating category; the modifier 2 indicates
a mid-range ranking; and the modifier 3 indicates that the bond ranks in the
lower end of its generic rating category.



                                       A-2

        Caa - Bonds that are rated Caa are of poor standing. These issues may be
in default or present elements of danger may exist 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.

Short-Term Note Ratings

        The following summarizes the two highest ratings used by S&P for
short-term notes:

        SP-1 - Loans bearing this designation evidence a very strong or strong
capacity to pay principal and interest. Those issues determined to possess
overwhelming safety characteristics will be given a plus sign designation.

        SP-2 - Loans bearing this designation evidence a satisfactory capacity
to pay principal and interest.

        The following summarizes the two highest ratings used by Moody's for
short-term notes and variable rate demand obligations:

        MIG-1/VMIG-1 - Obligations bearing these designations are of the best
quality, enjoying strong protection from established cash flows of funds for
their servicing or from established and broad-based access to the market for
refinancing, or both.

        MIG-2/VMIG-2 - Obligations bearing these designations are of high
quality with margins of protection ample although not so large as in the
preceding group.

Municipal Obligations Ratings

        The following summarizes the ratings used by S&P for Municipal
Obligations:

        AAA - This is the highest rating assigned by S&P to a debt obligation
and indicates an extremely strong capacity to pay interest and repay principal.

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

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

        BBB - This is the lowest investment grade. Debt rated BBB has an
adequate capacity to pay interest and repay principal. Although 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.

        BB, B, CCC, CC, C - Debt rated BB, B, CCC, CC and C is regarded, on
balance, as predominately speculative with respect to capacity to pay interest
and repay principal in accordance with the terms of the obligation. BB
represents a lower degree of speculation than B and C the highest degree of
speculation. While such bonds will likely have some quality and protective
characteristics, these are outweighed by large uncertainties or major risk
exposures to adverse conditions.

        BB - Bonds rated BB have less near-term vulnerability to default than
other speculative issues. However, they face 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.

        B - Bonds rated B have a greater vulnerability to default but currently
have 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 - This rating is typically applied to debt subordinated to senior
debt that is assigned an actual or implied CCC rating.

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

        Additionally, the rating CI is reserved for income bonds on which no
interest is being paid. Such debt is rated between debt rated C and debt rated
D.

        To provide more detailed indications of credit quality, the ratings from
"AA" to "CCC" may be modified by the addition of a plus or minus sign to show
relative standing within this major rating category.

        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. The D rating also will be used
upon the filing of a bankruptcy petition if debt service payments are
jeopardized.

        The following summarizes the highest four municipal ratings used by
Moody's:

        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 edge." Interest payments are protected by a large or exceptionally

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

        NOTE: Those bonds in the Aa, A, Baa, Ba and B groups which Moody's
believes possess the strongest investment attributes are designated by the
symbols Aa1, A1, Baa1, Ba1, and B1.

        Caa - Bonds that are rated Caa are of poor standing. These issues may be
in default or present elements of danger may exist 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.
