+ The Funds' investment adviser and co-administrator have undertaken to limit
  Total Fund Operating Expenses to the limit shown above through February 28,
  1999. Absent the waiver of fees by the Funds' investment adviser and co-
  administrator, Management Fees would equal .40%, Other Expenses would equal
  38% and Total Fund Operating Expenses would equal 1.03%. Other Expenses for
  the Fund are based on annualized estimates of expenses for the fiscal period
  ending December 31, 1998, net of any fee waivers or expense reimbursements.
  The investment adviser and co-administrator are under no obligation to
  continue these waivers.

  The expense table shows the costs and expenses that an investor will bear
directly or indirectly as an investor in each Fund. 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%. Long term shareholders of the Funds may pay more
than the economic equivalent of the maximum sales charges permitted by the
National Association of Securities Dealers, Inc.

INVESTMENT OBJECTIVES AND POLICIES
- --------------------------------------------------------------------------------
   
  The Warburg Pincus WorldPerks Money Market Fund (the "Money Market Fund") is a
diversified money market mutual fund whose investment objective is high current
income consistent with preservation of capital and liquidity. The Warburg Pincus
WorldPerks Tax Free Money Market Fund (the "Tax Free Fund") is a diversified
money market mutual fund whose objective is to provide investors with high
current income exempt from federal personal income taxes consistent with
preservation of capital and liquidity. Each objective may be changed only with
the approval of the investors in that Fund. There can be, of course, no
assurance that a Fund will achieve its investment objective. Investors should be
aware that the market value of the obligations in each Fund's portfolio can be
expected to vary inversely to changes in prevailing interest rates. See "Certain
Investment Strategies" for descriptions of certain types of investments the
Funds may make.
    
 
MONEY MARKET FUND
   
  The Money Market Fund will attempt to achieve its investment objective by
investing in a portfolio of high quality "money market" instruments consisting
of United States Treasury Bills, other obligations issued or guaranteed by the
United States government, its agencies or instrumentalities ("Government
Securities"); bank and bank holding company obligations such as certificates of
deposit, bankers' acceptances, time deposits, commercial paper and debt
obligations; commercial paper and notes of other corporate issuers, including
those with floating or variable rates of interest (including variable rate
master demand notes); and repurchase agreements with respect to the foregoing.
    
   
  In addition to the Government Securities which the Fund may purchase, except
during temporary defensive periods the Fund will invest more than 25% of its
assets in money market investments issued by (i) commercial and industrial banks
and savings and loan associations and their holding companies and other issuers
in the banking industry and (ii) consumer and industrial finance companies,
diversified financial service companies, investment banking, securities
brokerage and investment advisory companies, leasing companies and insurance
companies and other companies in the financial services sector. Although the
Fund intends to be diversified across (i) the banking industry and (ii) each of
the industries comprising the financial services sector, to the extent that the
Fund invests a significant portion of its assets in the banking industry and the
financial services sector it is subject to the risks associated with investing
in banking and financial services issuers. Up to 25% of the assets of the Fund
may be invested at any time in the debt obligations of issuers conducting their
principal business activities in any industry other than banking. In addition,
the Fund may invest up to 25% of its assets in the debt obligations of a single
issuer for a period of up to three business days. Securities issued by the
United States or its agencies or instrumentalities may be purchased without
regard to these limits.
    
 
                                        3
<PAGE>   10
 
TAX FREE FUND
   
  The Tax Free Fund expects that, except during temporary defensive periods, at
least 80% of the Fund's assets will be invested in short-term, high-quality
tax-exempt debt obligations issued by or on behalf of the states, territories
and possessions of the United States, the District of Columbia and their
respective authorities, agencies, instrumentalities and political subdivisions
("Municipal Securities"). Dividends paid by the Fund which are derived from
interest on Municipal Securities will be excluded from gross income for federal
income tax purposes, but will be subject to state and local personal income
taxes.
    
  Municipal Securities in which the Fund may invest include commercial paper,
notes and bonds. Interest on certain bonds issued after August 7, 1986 to
finance certain non-governmental activities ("Alternative Minimum Tax
Securities") is a preference item for purposes of the federal individual and
corporate alternative minimum taxes, but is exempt from regular federal income
tax. The Fund is authorized to invest up to 20% of its assets in Alternative
Minimum Tax Securities. 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 newly issued Municipal
Securities acquired by the Fund due to the possibility of federal, state and
local alternative minimum or minimum income tax liability on interest from
Alternative Minimum Tax Securities.
   
  The Fund may for defensive or other purposes invest without limit in certain
short-term taxable securities when the Fund's investment adviser or
sub-investment adviser believes that it would be in the best interests of the
Fund's investors. Taxable securities in which the Fund may invest on a short-
term basis are Government Securities, including repurchase agreements with banks
or securities dealers involving such securities, time deposits maturing in not
more than seven days, other debt securities, commercial paper and certificates
of deposit issued by United States branches of United States banks with assets
of $1 billion or more. At no time will more than 20% of the Fund's total assets
be invested in taxable short-term securities unless the Fund's investment
adviser has determined to temporarily adopt a defensive investment policy in the
face of an anticipated softening in the market for Municipal Securities in
general.
    
 
GENERAL
- --------------------------------------------------------------------------------
  PRICE AND PORTFOLIO MATURITY. Each Fund invests only in securities which are
purchased with and payable in U.S. dollars and which have (or, pursuant to
regulations adopted by the SEC, are deemed to have) remaining maturities of 397
calendar days or less at the date of purchase by a Fund. For this purpose,
variable rate master demand notes (as described below), which are payable on
demand, or, under certain conditions, at specified periodic intervals not
exceeding 397 calendar days, in either case on not more than
 
                                        4
<PAGE>   11
 
30 days' notice, will be deemed to have remaining maturities of 397 calendar
days or less. The Fund maintains a dollar-weighted average portfolio maturity of
90 days or less. The Fund follows these policies to maintain a constant net
asset value of $1.00 per share, although there is no assurance that it can do so
on a continuing basis.
   
  PORTFOLIO QUALITY AND DIVERSIFICATION. Each Fund will limit its portfolio
investments to securities that its Board determines present minimal credit risks
and which are "Eligible Securities" at the time of acquisition by a Fund. The
term Eligible Securities includes securities rated by the "Requisite NRSROs" in
one of the two highest short-term rating categories, securities of issuers that
have received such ratings with respect to other short-term debt securities and
comparable unrated securities. "Requisite NRSROs" means (i) any two nationally
recognized statistical rating organizations ("NRSROs") that have issued a rating
with respect to a security or class of debt obligations of an issuer, or (ii)
one NRSRO, if only one NRSRO has issued a rating with respect to such security
or issuer at the time that the Fund acquires the security. The Funds may
purchase securities that are unrated at the time of purchase that a Fund's
investment adviser and sub-investment adviser deem to be of comparable quality
to rated securities that the Fund may purchase. The NRSROs currently designated
as such by the SEC are Standard & Poor's Ratings Services ("S&P"), Moody's
Investors Service, Inc. ("Moody's"), FitchIBCA, Inc. and Duff and Phelps, Inc. A
discussion of the ratings categories of the NRSROs is contained in the Appendix
to the Fund's Statement of Additional Information.
    
  The Funds have adopted certain credit quality, maturity and diversification
requirements under Rule 2a-7 under the Investment Company Act of 1940, as
amended (the "1940 Act"), as operating policies. Under these policies, there are
two tiers of Eligible Securities, first and second tier, based on their ratings
by NRSROs or, if the securities are unrated, on determinations by a Fund's
investment adviser and sub-investment adviser. These policies generally restrict
a Fund from investing more than 5% of its assets in second tier securities and
limit to 5% of assets the portion that may be invested in any one issuer. In
addition, the credit quality and diversification policies vary to some extent
between the Money Market and the Tax Free Funds because the Tax Free Fund is a
tax exempt fund.
   
  YEAR 2000 COMPLIANCE. Many services provided to the Funds and their
shareholders by Warburg Pincus Asset Management, Inc., each Fund's investment
adviser ("Warburg"), and BlackRock Institutional Management Corporation, each
Fund's sub-investment adviser ("BIMC"), and certain of their affiliates
(collectively, the "Service Providers") and a Fund's 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
    
 
                                        5
<PAGE>   12
 
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 a Fund's 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.
    
 
PORTFOLIO INVESTMENTS
- --------------------------------------------------------------------------------
  Set forth below are descriptions of investments the Fund may make. More
detailed information concerning these investments and their related risks is
contained in the Fund's Statement of Additional Information.
  BANK OBLIGATIONS. The Money Market Fund may purchase bank obligations,
including United States dollar-denominated instruments issued or supported by
the credit of the United States or foreign banks or savings institutions having
total assets at the time of purchase in excess of $1 billion. While the Fund
will invest in obligations of foreign banks or foreign branches of United States
banks only if the Fund's investment adviser and sub-investment adviser deem the
instrument to present minimal credit risks, such investments may nevertheless
entail risks that are different from those of investments in domestic
obligations of United States banks due to differences in political, regulatory
and economic systems and conditions. Such risks include future political and
economic developments, the possible imposition of withholding taxes on interest
income, possible establishment of exchange controls or the adoption of other
foreign governmental restrictions which might adversely affect the payment of
principal and interest on such obligations. The Fund may also make
interest-bearing savings deposits in commercial and savings banks in amounts not
in excess of 5% of its assets.
  VARIABLE RATE MASTER DEMAND NOTES. Each Fund may also purchase variable rate
master demand notes, which are unsecured instruments that permit the
indebtedness thereunder to vary and provide for periodic adjustments in the
interest rate. Although the notes are not normally traded and there may be no
secondary market in the notes, a Fund may demand payment of principal and
accrued interest at any time and may resell the note at any time to a third
party. In the event an issuer of a variable rate master demand note defaulted on
its payment obligation, the Fund might be unable
 
                                        6
<PAGE>   13
 
to dispose of the note because of the absence of a secondary market and might,
for this or other reasons, suffer a loss to the extent of the default.
  GOVERNMENT SECURITIES. Government Securities in which the Fund may invest
include Treasury Bills, Treasury Notes and Treasury Bonds; other obligations
that are supported by the full faith and credit of the United States Treasury,
such as Government National Mortgage Association pass-through certificates;
obligations that are supported by the right of the issuer to borrow from the
Treasury, such as securities of Federal Home Loan Banks; and obligations that
are supported only by the credit of the instrumentality, such as Federal
National Mortgage Association bonds.
  REPURCHASE AGREEMENTS. Each Fund may agree to purchase money market
instruments from financial institutions such as banks and broker-dealers subject
to the seller's agreement to repurchase them at an agreed-upon date and price
("repurchase agreements"). The repurchase price generally equals the price paid
by a Fund plus interest negotiated on the basis of current short-term rates
(which may be more or less than the rate on the securities underlying the
repurchase agreement). Default by a seller, if the Fund is delayed or prevented
from exercising its rights to dispose of the collateral securities, could expose
the Fund to possible loss, including the risk of a possible decline in the value
of the underlying securities during the period while the Fund seeks to assert
its rights thereto. Repurchase agreements are considered to be loans by the Fund
under the 1940 Act.
  WHEN-ISSUED SECURITIES. Each Fund may purchase portfolio securities on a
"when-issued" basis. When-issued securities are securities purchased for
delivery beyond the normal settlement date at a stated price and yield. A Fund
will generally not pay for such securities or start earning interest on them
until they are received. Securities purchased on a when-issued basis are
recorded as an asset and are subject to changes in value based upon changes in
the general level of interest rates. The Fund expects that commitments to
purchase when-issued securities will not exceed 25% of the value of its total
assets absent unusual market conditions, and that a commitment by the Fund to
purchase when-issued securities will generally not exceed 45 days. The Fund does
not intend to purchase when-issued securities for speculative purposes but only
in furtherance of its investment objectives.
  STAND-BY COMMITMENTS. The Tax Free Fund may acquire "stand-by commitments"
with respect to Municipal Securities held in its portfolio. Under a stand-by
commitment, a dealer agrees to purchase, at the Fund's option, specified
Municipal Securities at a specified price. The principal risk of a stand-by
commitment is that the writer of a commitment may default on its obligation to
repurchase the securities acquired by it. The Fund intends to enter into
stand-by commitments only with brokers, dealers and banks that, in the opinion
of its advisers, present minimal credit risks. In evaluating the
creditworthiness of the issuer of a stand-by commitment, the investment adviser
and sub-investment adviser will review periodically relevant financial
information concerning the issuer's assets, liabilities and contingent claims.
 
                                        7
<PAGE>   14
 
The Fund will acquire stand-by commitments solely to facilitate portfolio
liquidity and does not intend to exercise its rights thereunder for trading
purposes.
  THIRD PARTY PUTS. The Tax Free Fund may purchase long-term fixed rate bonds
that have been coupled with an option granted by a third party financial
institution allowing the Fund at specified intervals to tender (or "put") the
bonds to the institution and receive the face value thereof (plus accrued
interest). The Fund receives a short-term rate of interest (which is
periodically reset), and the interest rate differential between that rate and
the fixed rate on the bond is retained by the financial institution. The
financial institution does not provide credit enhancement, and in the event that
there is a default in the payment of principal or interest, or downgrading of a
bond to below investment grade, or a loss of the bond's tax-exempt status, the
put option will terminate automatically, the risk to the Fund will be that of
holding such a long-term bond and the dollar-weighted average maturity of its
portfolio would be adversely affected. See the Fund's Statement of Additional
Information, "Investment Policies -- Additional Information and Policies."
   
  SPECIAL CONSIDERATIONS AND RISK FACTORS RELATING TO THE MONEY MARKET FUND. To
the extent that the Money Market Fund invests a significant portion of its
assets in money market instruments issued by companies in the banking industry
and the financial services sector, the Fund is subject to the risks associated
with investing in banking and financial services issuers. The companies within
the banking industry and the financial services sector are subject to extensive
regulation, rapid business changes, volatile performance dependent upon the
availability and cost of capital and prevailing interest rates, and significant
competition. General economic conditions significantly affect these companies.
Credit and other losses resulting from the financial difficulty of borrowers or
other third parties have a potentially adverse effect on companies in this
industry. Investment banking, securities brokerage and investment advisory
companies are particularly subject to government regulation and the risks
inherent in securities trading and underwriting activities. Insurance companies
are particularly subject to government regulation and rate setting, potential
antitrust and tax law changes, and industry-wide pricing and competition cycles.
Property and casualty insurance companies may also be affected by weather and
other catastrophes. Life and health insurance companies may be affected by
mortality and morbidity rates, including the effects of epidemics. Individual
insurance companies may be exposed to reserve inadequacies, problems in
investment portfolios and failures by reinsurance carriers.
    
  SPECIAL CONSIDERATIONS AND RISK FACTORS RELATING TO THE TAX FREE FUND. In
seeking to achieve its investment objective the Tax Free Fund may invest all or
any part of its assets in Municipal Securities which are industrial development
bonds. Moreover, although the Fund does not currently intend to do so on a
regular basis, it may invest more than 25% of its assets in Municipal Securities
 
                                        8
<PAGE>   15
 
the interest on which is paid solely from revenues of economically related
projects, if such investment is deemed necessary or appropriate by the Fund's
investment adviser and sub-investment adviser. To the extent that the Fund's
assets are concentrated in Municipal Securities payable from revenues on
economically related projects and facilities, the Fund will be subject to the
peculiar risks presented by such projects to a greater extent than it would be
if the Fund's assets were not so concentrated.
  The Tax Free Fund also invests in securities backed by guarantees from banks
and other financial institutions. The Fund's ability to maintain a stable share
price is largely dependent upon such guarantees, which are not supported by
federal deposit insurance. Consequently, changes in the credit quality of these
institutions could have an adverse impact on securities they have guaranteed or
backed, which could cause losses to the Fund and affect its share price.
  Other considerations affecting the Tax Free Fund's investments in Municipal
Securities are summarized in the Statement of Additional Information.
 
INVESTMENT GUIDELINES
- --------------------------------------------------------------------------------
   
  Each Fund may invest up to an aggregate of 10% of its net assets in illiquid
securities with contractual or other restrictions on resale and other
instruments which are not readily marketable. Each Fund is also authorized to
borrow and to enter into reverse repurchase agreements in an amount of up to 10%
of its total assets for temporary or emergency purposes, but not for leverage,
and to pledge its assets to the same extent in connection with such borrowings.
Whenever borrowings exceed 5% of the value of a Fund's total assets, the Fund
will not make any additional investments (including roll-overs). A more detailed
description of these policies, together with an enumeration of additional
investment restrictions that each Fund has adopted and that cannot be changed
without the approval of the holders of a majority of the Fund's outstanding
shares, is contained in the Fund's Statement of Additional Information.
    
 
MANAGEMENT OF THE FUNDS
- --------------------------------------------------------------------------------
   
  INVESTMENT ADVISER. Each Fund employs Warburg as investment adviser and BIMC
as sub-investment adviser. In its Advisory Agreement with each Fund, Warburg has
agreed to be responsible, subject to the supervision and direction of the Board,
for the Fund's investment program, including decisions concerning: (i) the
specific types of securities to be held by the Fund and the proportion of the
Fund's assets that should be allocated to such investments during particular
market cycles, (ii) the specific issuers whose securities will be purchased or
sold by the Fund, (iii) the maximum maturity (under one year) of its portfolio
investments, (iv) the appropriate average weighted maturity of its portfolio in
light of current market conditions and (v) with respect to the Tax Free Fund,
the extent to which taxable securities will be purchased for and held by the Tax
Free Fund and the extent to which
    
 
                                        9
<PAGE>   16
 
securities other than Municipal Securities will be purchased for and held by
the Tax Free Fund. In addition, Warburg has each agreed to supervise the
performance by the sub-investment adviser of the functions described below.
   
  For the services provided pursuant to the Advisory Agreement, Warburg is
entitled to receive a fee, computed daily and payable monthly, at the annual
rate of .40% of the value of each Fund's average daily net assets, out of which
Warburg pays BIMC for sub-investment advisory services. Warburg, BIMC and each
Fund's administrators may voluntarily waive a portion of their fees from time to
time and temporarily limit the expenses to be paid by a Fund.
    
   
  Warburg is a professional investment advisory firm which provides investment
services to investment companies, employee benefit plans, endowment funds,
foundations and other institutions and individuals. As of August 31, 1998,
Warburg managed approximately $18.4 billion of assets, including approximately
$10.2 billion of investment company assets. Incorporated in 1970, Warburg is
indirectly controlled by Warburg, Pincus & Co. ("WP&Co."), which has no business
other than being a holding company of Warburg and its affiliates. Lionel I.
Pincus, the managing partner of WP&Co., may be deemed to control both WP&Co. and
Warburg. Warburg's address is 466 Lexington Avenue, New York, New York
10017-3147.
    
   
  SUB-INVESTMENT ADVISER. BIMC, formerly PNC Institutional Management
Corporation, a wholly owned indirect subsidiary of PNC Bank, National
Association ("PNC"), serves as each Fund's sub-investment adviser. BIMC was
organized in 1977 by PNC to perform advisory services for investment companies
and has its principal offices at 400 Bellevue Parkway, Wilmington, Delaware
19809. As of July 31, 1998, BIMC served as investment adviser to 20 mutual fund
portfolios and as sub-investment adviser to 15 mutual funds, having total assets
exceeding $42 billion.
    
  As sub-investment adviser, BIMC has agreed to implement each Fund's investment
program as determined by the Board and Warburg. BIMC will supervise the
day-to-day operations of the relevant Fund and perform the following services:
(i) providing investment research and credit analysis concerning the Fund's
investments, (ii) placing orders for all purchases and sales of the Fund's
portfolio investments and (iii) maintaining the books and records required to
support the Fund's operations. BIMC also calculates the Fund's net asset value,
provides accounting services for the Fund and assists in related aspects of the
Fund's operations.
   
  CO-ADMINISTRATORS. The Funds employ Credit Suisse Asset Management Ltd., a
wholly-owned subsidiary of Credit Suisse Group ("CSAM"), as a co-administrator.
As co-administrator, CSAM provides shareholder liaison services to the Fund
including responding to shareholder inquiries and providing information on
shareholder investments. CSAM also performs a variety of other services,
including furnishing certain executive and administrative services, acting as
liaison between a Fund and its various service providers, furnishing corporate
secretarial services, which include preparing materials for meetings of the
Board, assisting in the preparation of
    
                                       10
<PAGE>   17
 
   
proxy statements, annual and semiannual reports, tax returns and monitoring and
developing compliance procedures for the Fund. As compensation, each Fund pays
to CSAM a fee calculated at an annual rate of .10% of the Fund's average daily
net assets, exclusive of out-of-pocket expenses. CSAM may delegate to
Counsellors Funds Service, Inc., a wholly-owned subsidiary of Warburg,
responsibility for most of its co-administrative services. CSAM's principal
offices are located at Beaufort House, 15 St. Botolph Street, GB-London EC3A
7JJ.
    
   
  The Funds also employ PFPC Inc. ("PFPC"), an indirect, wholly owned subsidiary
of PNC Bank Corp., as a co-administrator. As a co-administrator, PFPC calculates
a Fund's net asset value, provides all accounting services for the Fund and
assists in related aspects of the Fund's operations. As compensation, the Fund
pays to PFPC a fee calculated at an annual rate of .10% of the Fund's first $500
million in average daily net assets, .075% of the next $1 billion in average
daily net assets, and .05% of average daily net assets over $1.5 billion,
subject to a minimum annual fee and exclusive of out-of-pocket expenses. PFPC
has its principal offices at 400 Bellevue Parkway, Wilmington, Delaware 19809.
    
  CUSTODIAN. PNC serves as the custodian of each Fund's assets. PNC is a
subsidiary of PNC Bank Corp. and its principal business address is 1600 Market
Street, Philadelphia, Pennsylvania 19103.
  TRANSFER AGENT. State Street Bank and Trust Company ("State Street") serves as
shareholder servicing agent, transfer agent and dividend disbursing agent for
the Funds. State Street has delegated to Boston Financial Data Services, Inc.,
an affiliated company ("BFDS"), responsibility for most shareholder servicing
functions. State Street's principal business address is 225 Franklin Street,
Boston, Massachusetts 02110. BFDS's principal business address is 2 Heritage
Drive, North Quincy, Massachusetts 02171.
   
  DISTRIBUTOR. Counsellors Securities Inc. ("Counsellors Securities") serves as
distributor of the shares of the Funds. Counsellors Securities is a wholly owned
subsidiary of Warburg and is located at 466 Lexington Avenue, New York, New York
10017-3147. Counsellors Securities receives a fee at an annual rate equal to
 .25% of the average daily net assets of each Fund's Common Shares for
distribution services, pursuant to a shareholder servicing and distribution plan
(the "12b-1 Plan") adopted by each Fund pursuant to Rule 12b-1 under the 1940
Act. Amounts paid to Counsellors Securities under a 12b-1 Plan may be used by
Counsellors Securities to cover expenses that are primarily intended to result
in, or that are primarily attributable to, (i) the sale of the Common Shares,
including payments in connection with the Funds' participation in the Northwest
Airlines WorldPerks program, (ii) ongoing servicing and/or maintenance of the
accounts of Common Shareholders of a Fund and (iii) sub-transfer agency
services, subaccounting services or administrative services related to the sale
of the Common Shares, all as set forth in the 12b-1 Plans. Payments under the
12b-1 Plans are not tied exclusively to the distribution expenses actually
incurred by Counsellors
    
 
                                       11
<PAGE>   18
 
   
Securities and the payments may exceed distribution expenses actually
incurred. The Board of the Funds evaluate the appropriateness of the 12b-1 Plans
on a continuing basis and in doing so consider all relevant factors, including
expenses borne by Counsellors Securities and amounts received under the 12b-1
Plans. Warburg or its affiliates may also bear a portion of the expense for the
Funds' participation in the WorldPerks program.
    
  DIRECTORS AND OFFICERS. The officers of each Fund manage its day-to-day
operations and are directly responsible to its Board. The Board of a Fund sets
broad policies for each Fund and chooses the Fund's officers. A list of the
Directors and officers of each Fund and a brief statement of their present
positions and principal occupations during the past five years is set forth in
the Statement of Additional Information.

  Investments in each Fund are eligible to accrue WorldPerks Bonus Miles in
Northwest Airlines' WorldPerks Program, based on the amount and length of time
of investment. The WorldPerks Program offers free and discounted award travel on
Northwest Airlines, KLM Royal Dutch Airlines and other WorldPerks partner
airlines. If you are not a member of the WorldPerks Program, you can call
Northwest Airlines at 800-44-PERKS to enroll before you make an investment in a
Fund. Northwest Airlines WorldPerks Bonus Miles accrue daily at an annual rate
of one mile per $4 invested in a Fund. Miles will be posted monthly in arrears
to each shareholder's WorldPerks account based on the shareholder's average
daily Fund account balance during the previous month. In addition, from November
1998 through April 1999, investors will earn 200 additional miles for each month
they have at least $5,000 invested in a Fund. Accordingly, investors can receive
up to 1,200 additional Bonus Miles by investing in a Fund by November 30, 1998.
    
   
  The average daily balance is calculated by adding each day's balance and
dividing by the number of days in the month. For example, the average daily
balance on a $10,000 account funded on the 16th day of a month having 30 days
(and maintained at that balance through the end of the month) would be $5,000.
Mileage received for that month would be 105 miles. If the same balance were
maintained through the next 30-day month, the average daily balance would be
$10,000, and the mileage would be 209 miles that month and every month the
$10,000 investment was maintained in a Fund. All mileage credits of less than
one mile will be rounded up to the nearest whole mile when credited. These miles
would appear on subsequent Northwest Airlines WorldPerks Mileage Summary
statements. Investors should telephone Warburg Pincus Funds at 800-WARBURG
(800-927-2874) for information or assistance regarding the WorldPerks
InvestorMiles Program.
    
   
  The posting of WorldPerks Bonus Miles in connection with Fund investments may
be terminated or the amount of miles awarded in relation to dollars invested may
be limited or changed. Investors should refer to Northwest WorldPerks member
materials for information about program
    
 
                                       12

features. Northwest Airlines may change the WorldPerks Program rules, program
partners, regulations, benefits, conditions of participation or mileage levels,
in whole or in part, at any time, without notice to shareholders or Warburg,
even though changes may affect the value of mileage or FlyWrite(SM) certificates
already accumulated. Award travel is subject to seat availability. Northwest
Airlines WorldPerks travel awards, mileage accrual and special offers are
subject to governmental regulations.
    
 
HOW TO OPEN AN ACCOUNT
- --------------------------------------------------------------------------------
   
  Accounts in the Funds may only be opened by WorldPerks members. If you are not
a member of the WorldPerks Program, you can call Northwest Airlines at
800-44-PERKS to enroll before you make an investment in a Fund.
    
   
  In order to invest in a Fund, an investor must first complete and sign an
account application. To obtain an application, an investor may telephone Warburg
Pincus Funds at 800-927-2874. An investor may also obtain an account application
                                                                              by
                                                                         writing
                                                                             to:

their own tax advisers about the establishment of UTMA or UGMA accounts.
Retirement plans, trusts, corporations, partnerships and certain other legal
entities cannot invest in the Funds.
    
   
  ACCOUNT REGISTRATION AND MILEAGE AWARDS. Because of limitations applicable to
the Northwest Airlines WorldPerks Program, airline miles will be credited
exclusively to the WorldPerks account of the first-named person on a joint
account and the minor child on an UTMA/UGMA account.
    
   
  CHANGES TO ACCOUNT. For information on how to make changes to an account,
including changes to account registration, address and/or privileges, an
investor should telephone Warburg Pincus Funds at 800-927-2874. Shareholders are
responsible for maintaining current account registrations and addresses with the
Fund. No interest will be paid on amounts represented by uncashed distribution
or redemption checks.

HOW TO PURCHASE SHARES
    
- --------------------------------------------------------------------------------
   
  Shares of each Fund may be purchased either by mail or, with special advance
instructions, by wire and automated clearing house transactions ("ACH on
Demand"). The minimum initial investment in each Fund is $5,000 and the minimum
subsequent investment is $100. For UTMA/UGMA accounts in the Money Market Fund,
the minimum initial investment is $500. Subsequent minimum investments are $50
under the Automatic Monthly Investing Plan or by ACH on Demand, as described
below. Each Fund reserves the right to change the initial and subsequent
investment minimum requirements at any time and to charge investors a fee if
their account balance falls below the initial investment minimum due to
redemptions. 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 or its 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 or any
imposition of a fee for small accounts.
    
  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 above. 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. In the interest of
economy and convenience, physical certificates representing shares in the Fund
are not normally issued.
   
  BY MAIL. If the investor desires to purchase shares by mail, a check or money
order made payable to a Fund or Warburg Pincus Funds (in U.S. currency) should
be sent along with the completed account application to the address set forth
above. Checks payable to the investor and endorsed to the order of the Fund or
Warburg Pincus 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 a Fund calculates its net asset value (a "business
day"), the purchase will be made at the relevant 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 relevant
Fund's net asset value next determined after payment has been received. Checks
or money orders 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 money order are entitled to receive dividends and
distributions beginning on the day payment is received. Checks or money orders
in payment for shares of more than one Warburg Pincus Fund should be made
payable to Warburg Pincus Funds and should be accompanied by a breakdown of
amounts to be invested in each fund. If a check used for purchase does not
    
 
                                       14
<PAGE>   21
 
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 shares in a Fund by wiring funds from
their banks. Telephone orders by wire will not be accepted until a completed
account application in proper form has been received and accepted and an account
number has been established. Investors should place an order with the Fund prior
to wiring funds by telephoning 800-927-2874. 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
   
[Warburg Pincus Fund name]
    
DDA# 9904-649-2
   
F/F/C: [Account Number and Account Registration]
    
  If a telephone order is received before 12:00 p.m. (Eastern time) and payment
by wire is received on the same day in proper form in accordance with
instructions set forth above, the purchase will be executed at noon and shares
are entitled to dividends and distributions beginning on that day. If payment by
wire is received in proper form before 12:00 p.m. without a prior telephone
order, that purchase and any telephone orders placed after 12:00 p.m. for which
payment by wire is received on the same day in proper form, will be priced at
the net asset value of the Fund as of the close of regular trading on the NYSE
on that day and is entitled to dividends and distributions beginning the next
business day. Payment for orders that are not accepted will be returned to the
prospective investor after prompt inquiry. If a telephone order is placed and
payment by wire is not received on the same day, the Fund will cancel the
purchase and the investor may be liable for losses or fees incurred.
   
  AUTOMATIC MONTHLY INVESTMENT PLAN AND ACH ON DEMAND. The Automatic Monthly
Investment Plan allows shareholders to authorize a Fund or its agent to debit
their bank account monthly ($50 minimum) for the purchase of Fund shares on or
about either the tenth or twentieth calendar day of each month. Shareholders may
also purchase shares by calling 800-927-2874 on any business day to request
direct debit or credit (for redemptions) of their bank account through an ACH on
Demand transaction.
    
   
  To establish the Automatic Monthly Investment Plan and/or ACH on Demand
option, obtain a separate application or complete the relevant section of the
account application. Only an account maintained at a financial institution which
is an automated clearing house member may be used, and one common name must
appear on both the shareholder's Fund registration and bank account
registration. Shareholders using this service must satisfy the initial
investment minimum for the Fund prior to or concurrent with the start of any
Automatic Monthly Investment Plan or ACH on Demand transaction. Please contact
Warburg Pincus Funds at 800-927-2874 for additional information. Investors
should allow a period of up to 30 days in
    
 
                                       15
<PAGE>   22
 
order to implement an Automatic Monthly Investment Plan or ACH on Demand
transaction. The failure to provide complete information could result in further
delays.
  If an ACH on Demand transaction request is received prior to the close of
regular trading on the NYSE, the shares will be priced according to the net
asset value of Fund shares on that day and are entitled to dividends and
distributions as described above for wire purchases. If a request is received at
or after the close of regular trading on the NYSE, the shares will be priced at
the relevant Fund's net asset value on the following business day.
  TELEPHONE TRANSACTIONS. Unless otherwise indicated on the account application
or if the ACH on Demand option is elected an investor may request transactions
by telephone. Investors should realize that in conducting transactions by
telephone they may be giving up a measure of security that they might have if
they were to conduct these transactions in writing. Neither the Fund nor its
agents will be liable for following instructions communicated by telephone that
it reasonably believes to be genuine. Reasonable procedures will be employed on
behalf of the Fund designed to give reasonable assurance that instructions
communicated by telephone are genuine. Such procedures include providing written
confirmation of telephone transactions, tape recording telephone instructions
and requiring specific personal information prior to acting upon telephone
instructions.
   
  GENERAL. Each Fund reserves the right to reject an account application or any
specific purchase order, including certain purchases made by exchange (see "How
to Redeem and Exchange Shares -- Exchange of Shares" below). For example,
purchase orders may be refused if, in Warburg's opinion, 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 the 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
the 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).
   
  Shares of the Fund may either be redeemed by mail or by telephone. Investors
should realize that in using the telephone redemption and exchange option, they
may be giving up a measure of security that they may have if they were to redeem
or exchange their shares in writing. If an investor desires to redeem his shares
by mail, a written request for redemption should be sent to the address
indicated above under "How to Open an Account." An investor should be sure that
the redemption request identifies the relevant Fund, the
    
                                       16
<PAGE>   23
 
   
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. If an investor has
applied for the telephone redemption feature on his account application, he may
redeem his shares by calling Warburg Pincus Funds at 800-927-2874. An investor
making a telephone withdrawal should state (i) the name of the Fund, (ii) the
account number of the Fund, (iii) the name of the investor(s) appearing on the
Fund's records, (iv) the amount to be withdrawn and (v) the name of the person
requesting the redemption.
    
   
  After receipt of the redemption request by mail or by telephone, 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. The Funds
currently do not impose a service charge for effecting wire transfers but each
Fund reserves the right to do so in the future. During periods of significant
economic or market change, telephone redemptions may be difficult to implement.
If an investor is unable to contact Warburg Pincus Funds by telephone, an
investor may deliver the redemption request by mail at the address shown above
under "How to Open an Account." Although each Fund will redeem shares purchased
by check, through the Automatic Monthly Investment Plan or by ACH on Demand
before the funds or check clear, payments of the redemption proceeds will be
delayed for up to five days (for funds received through the Automatic Monthly
Investment Plan or by ACH on Demand) or up to 10 days (for check purchases) from
the date of purchase. Investors should consider purchasing shares using a
certified or bank check, money order or federal funds wire if they anticipate an
immediate need for redemption proceeds.
    
  Shares are redeemed at the net asset value per share next determined after
receipt of a redemption order by a Fund or its agent. 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 Warburg, 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.
  Although each Fund intends to use its best efforts to maintain its net asset
value per share at $1.00, 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.
 
                                       17
<PAGE>   24
 
   
  If, due to redemptions, the value of an investor's account drops to less than
$750 ($250 in the case of an UTMA/UGMA account), each Fund reserves the right to
redeem the shares in that account at net asset value. Prior to any redemption, a
Fund will notify an investor in writing that this account has a value of less
than the minimum. The investor will then have 60 days to make an additional
investment before a redemption will be processed by the Fund.
    
   
  Redemption By Check. An individual investor who is the record owner of Fund
shares may request a supply of checks. Checks may be made payable to the order
of any person in any amount not less than $500. When a check is presented to
State Street for payment, State Street, as agent for the investor, causes the
relevant Fund to redeem a sufficient number of shares in the investor's account
to cover the amount of the check. A Fund may, in its discretion, waive the
checkwriting minimum requirements with respect to investors who are employees of
Warburg or its affiliates or persons with whom Warburg has entered into an
investment advisory agreement.
    
   
  Investors are entitled to receive dividends on the shares to be redeemed
through the day the check is presented to State Street for payment. If an
investor owns insufficient shares to cover a check, the check will be returned
to the investor marked "insufficient funds." Canceled checks will be returned to
the investor. Neither Fund currently assesses a charge for checks written in
amounts greater than the minimum. However each Fund reserves the right at any
time to terminate or modify the check redemption procedure, to limit the number
of checks that may be presented for payment within any given time period, to
impose a service charge or to charge for checks. A Fund may also charge an
investor's account for returned checks and for effecting stop orders.
    
   
  AUTOMATIC CASH WITHDRAWAL PLAN. Each Fund offers investors an automatic cash
withdrawal plan under which investors may elect to receive periodic cash
payments of at least $250 monthly or quarterly. To establish this service,
complete the "Automatic Withdrawal Plan" section of the account application and
attach a voided check from the bank account to be credited. For further
information regarding the automatic cash withdrawal plan or to modify or
terminate the Plan, investors should contact Warburg Pincus Funds at
800-927-2874.
    
   
  EXCHANGE OF SHARES. An investor may exchange shares of a Fund for shares of
the other Fund or for Common Shares of any other Warburg Pincus Fund at their
respective net asset values. An investor cannot currently earn Northwest
Airlines WorldPerks mileage credit for any investments in any Warburg Pincus
Fund other than the Funds described in this Prospectus. Exchanges may be
effected by mail or by telephone in the manner described under "Redemption of
Shares" above. If an exchange request is received by Warburg Pincus Funds or
their 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.
    
                                       18
<PAGE>   25
 
   
  The exchange privilege is available to shareholders residing in any state in
which the 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
redemption. Therefore, the investor may realize a taxable gain or loss in
connection with the exchange. Investors wishing to exchange shares of a Fund for
shares in another Warburg Pincus Fund should review the prospectus of the other
fund prior to making an exchange. For further information regarding the exchange
privilege or to obtain a current prospectus for another Warburg Pincus Fund, an
investor should contact Warburg Pincus Funds at 800-927-2874.
    
  The Funds reserve the right to refuse exchange purchases by any person or
group if, in an adviser'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. Examples of when an exchange
purchase could be refused are when the 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 30 days' notice to shareholders.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
   
  DIVIDENDS AND DISTRIBUTIONS. Each Fund calculates its dividends from net
investment income. Net investment income is declared daily and paid monthly. Net
investment income earned on weekends and when the NYSE is not open will be
computed on the previous business day. Distributions of long-term capital gains,
if any, generally are declared and paid annually at the end of the Fund's fiscal
year in which they are earned. Distributions of short-term capital gains, if
any, are declared and paid annually, at the end of the fiscal year in the case
of the Tax Free Fund, and periodically, as the Board determines, in the case of
the Money Market Fund. Unless an investor instructs a Fund to pay dividends or
capital gains distributions in cash, dividends and distributions will
automatically be reinvested in additional 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 the address set forth under
"How to Open an Account" or by calling Warburg Pincus Funds at 800-927-2874.
    
  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. A Fund, if it qualifies as a regulated
investment company, will be subject to a 4% non-deductible excise
                                       19
<PAGE>   26
 
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. As long as the Tax Free Fund qualifies as a regulated investment company
and meets certain other Code requirements (including the requirement that at
least 50% of its assets are invested in tax-exempt obligations at the close of
each quarter of its taxable year), distributions of tax-exempt interest income
will be excluded from an investor's income for federal income tax purposes.
   
  Such exempt interest dividends paid by the Tax Free Fund may be excluded by
investors from their gross incomes for federal income tax purposes, although (i)
such exempt interest dividends will be a tax preference item for purposes of the
federal individual and corporate alternative minimum taxes to the extent they
are derived from Alternative Minimum Tax Securities 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. In addition,
corporate investors may incur a greater federal environmental tax liability
through the receipt of Fund dividends and distributions if the tax is reinstated
as currently proposed. Investors who are "substantial users" (or "related
persons" of substantial users) within the meaning of the Code of facilities
financed by Alternative Minimum Tax Securities should consult their tax advisers
as to whether the Tax Free Fund is a desirable investment.
    
  Dividends paid by a Fund from its taxable net investment income (if any, in
the case of the Tax Free Fund) and distributions of any net short-term capital
gains (whether from tax-exempt or taxable obligations) are taxable to investors
as ordinary income, whether received in cash or reinvested in additional shares
of the Fund. As a general rule, an investor's gain or loss on a sale or
redemption of his Fund shares will be a long-term capital gain or loss if he has
held his shares for more than one year and will be short-term capital gain or
loss if he has held his shares for one year or less. Each Fund does not expect
to realize long-term capital gains and, therefore, it is unlikely that any
portion of the dividends or distributions paid by a Fund will be taxable to
investors as long-term capital gains. An investor in the Tax Free Fund who
redeems his shares prior to the declaration of a dividend may lose tax exempt
status on accrued income attributable to tax exempt Municipal Securities.
Investors may be proportionately liable for taxes on income and gains of a Fund,
but investors not subject to tax on their income will not be required to pay tax
on amounts distributed to them. Each Fund's dividends and distributions will not
qualify for the dividends-received deduction allowed to corporations. The Funds'
investment activities should not result in unrelated business taxable income to
a tax exempt investor.
  GENERAL. Statements as to the tax status of each investor's dividends and
distributions are mailed annually. In the case of the Tax Free Fund, these
statements set forth the dollar amount of income excluded or exempt from
                                       20
<PAGE>   27
 
   
federal income taxes, and the dollar amount, if any, subject to taxation. These
statements also designate the amount of exempt-interest dividends that is a
specific preference item for purposes of the federal individual and corporate
alternative minimum taxes. Each investor in the Money Market Fund will also
receive, if applicable, various written notices after the close of the 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 the tax consequences, if any, relating to the receipt of
Northwest Airlines WorldPerks mileage credit, and their state and local taxes
that may apply to dividends and distributions received from the Funds. In this
regard, investors should be aware that if a portion of any dividend is derived
from interest on United States government obligations, that portion may be
subject to tax by certain states, even though such interest, if received
directly by an investor, would be exempt from state income tax.
    
 
NET ASSET VALUE
- --------------------------------------------------------------------------------
  Each Fund's net asset value per share is calculated at noon and 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 is computed by adding the value of
the Fund's assets, deducting liabilities and dividing the result by the number
of outstanding shares. Fund securities are valued on the basis of amortized
cost, which involves valuing a portfolio instrument at its cost initially and
thereafter assuming a constant amortization to maturity of any discount or
premium, regardless of the impact of fluctuating interest rates on the market
value of the instrument.
 
PERFORMANCE
- --------------------------------------------------------------------------------
  From time to time, a Fund may advertise its yield and effective yield and, in
the case of the Tax Free Fund, its tax equivalent yield. The yield of a Fund
refers to the income generated by an investment in the shares over a seven-day
period, which is then annualized. That is, the amount of income generated by the
investment during that week is assumed to be generated each week over a 52-week
period and is shown as a percentage of the investment. The effective yield is
calculated similarly but, when annualized, assumes that income earned by an
investment in the Fund is reinvested. The effective yield will be slightly
higher than the yield because of the compounding effect of this assumed
reinvestment. The tax equivalent yield shows the taxable yield an investor in
the highest applicable tax bracket would have to earn to equal the

Tax Free Fund's tax-free yield after the imposition of federal, state and local
personal income taxes. The Tax Free Fund's tax equivalent yield is calculated by
dividing the Fund's tax-exempt yield by one minus the highest level of the
combined federal, state and local tax rates. Yield, effective yield and tax
equivalent yield may be shown by means of schedules, charts or graphs.
   
  Investors should note that yield, effective yield and tax equivalent yield
figures are based on historical earnings and are not intended to indicate future
performance. The Fund's Statement of Additional Information describes the method
used to determine the Fund's yield. Current yield figures may be obtained by
calling Warburg Pincus Funds at 800-927-2874.
    
   
  A Fund may compare its performance with (i) that of other mutual funds as
listed in the rankings prepared by Lipper Analytical Services, Inc. or similar
investment services that monitor the performance of mutual funds or (ii) in the
case of the Tax Free Fund, an average of the yields of similar tax-exempt money
market funds based on information contained in Donoghue's Money Market Fund
Report, which is published weekly by the Donoghue Organization or (iii) in the

GENERAL INFORMATION
- --------------------------------------------------------------------------------
   
  ORGANIZATION. The Money Market Fund and the Tax Free Fund were incorporated on
July 24, 1998 under the laws of the State of Maryland as "Warburg, Pincus Money
Market Fund, Inc." and "Warburg, Pincus Tax Free Money Market Fund, Inc.,"
respectively. On September   , 1998, the Money
    
                                       22
<PAGE>   29
 
   
Market Fund and the Tax Free Fund amended their respective charters and changed
the Funds' names to "Warburg, Pincus WorldPerks Money Market Fund, Inc." and
"Warburg, Pincus WorldPerks Tax Free Money Market Fund, Inc.," respectively.
Each Fund's charter authorizes the Board to issue three billion full and
fractional shares of capital stock, $.001 par value per share, of which two
billion shares are designated Advisor Shares. Under a 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. The Board
may similarly classify or reclassify any class of shares into one or more series
and, without shareholder approval, may increase the number of authorized shares
of the Fund. Since no Advisor Shares are outstanding for the Fund, references to
"shares" in this prospectus refer solely to the common shares of the Fund unless
the context otherwise requires.
    
  MULTI-CLASS STRUCTURE. Although neither Fund currently does so, each Fund is
authorized to offer a separate class of shares, the Advisor Shares, pursuant to
a separate prospectus. Individual investors could only purchase Advisor Shares
through institutional shareholders of record, broker-dealers, financial
institutions, depository institutions, retirement plans and other financial
intermediaries. Shares of each class would represent equal pro rata interests in
the relevant Fund and accrue dividends and calculate net asset value and
performance quotations in the same manner. Because of the higher fees paid by
the Advisor Shares, the total return on such shares can be expected to be lower
than the total return on common 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 the 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 Investment
Program). 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
                                       23

a Fund, as well as certain statistical characteristics of the Fund, may be
obtained by calling Warburg Pincus Funds at 800-927-2874 or on the Warburg
Pincus Funds Web site at www.warburg.com.

                              INVESTMENT OBJECTIVES

                  The investment objective of the Money Market Fund is to
provide investors with high current income consistent with liquidity and
stability of principal.

                  The investment objective of the Tax Exempt Fund is to provide
investors with as high a level of current income that is exempt from federal
personal income taxes as is consistent with preservation of capital and
liquidity.

                              MUNICIPAL SECURITIES

   
                  Under normal circumstances, at least 80% of the Tax Exempt
Fund's assets will be invested in Municipal Securities. Municipal Securities
include short-term 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 securities that are issued by or on behalf of
public authorities to finance various privately-operated facilities are included
within the term Municipal Securities if the interest paid thereon is exempt from
federal income tax.
    

                  The two principal types of Municipal Securities consist of
"general obligation" and "revenue" issues, and the Tax Exempt Fund's portfolio
may include "moral obligation" issues, which are normally issued by special
purpose authorities. General obligation bonds are secured by the issuer's pledge
of its full faith, credit and taxing power for the payment of principal and
interest. Revenue bonds are payable only from the revenues derived from a
particular facility or class of facilities or in some cases, from the proceeds
of a special excise tax or other specific revenue source such as the user of the
facility being financed. Private activity securities held by the Fund are in
most cases revenue bonds and are not payable from the unrestricted revenues of
the issuer. Consequently, the credit quality of such private activity securities
is usually directly related to the credit standing of the corporate user of the
facility involved.

                  There are, of course, variations in the quality of Municipal
Securities, both within a particular classification and between classifications,
and the yields on Municipal Securities depend upon a variety of factors,
including general money market conditions, the financial condition of the
issuer, general conditions of the municipal bond market, the size of a
particular offering, the maturity of the obligation and the rating of the issue.
The ratings of rating agencies represent their opinions as to the quality of
Municipal Securities. It should be emphasized, however, that ratings are general
and are not absolute standards of quality, and Municipal Securities with the
same maturity, interest rate and rating may have different yields while
Municipal Securities of the same maturity and interest rate with different
ratings may have the same yield. Subsequent to its purchase by the Tax Exempt
Fund, an issue of Municipal Securities may cease to be rated or its rating may
be reduced below the minimum rating required for purchase by the Fund. The
Fund's investment adviser and sub-investment adviser will consider such an event
in determining whether the Fund should continue to hold 



                                       2
<PAGE>   34

the obligation. See the Appendix attached hereto for further information
concerning ratings and their significance.

                  An issuer's obligations under its Municipal Securities are
subject to the provisions of bankruptcy, insolvency and other laws affecting the
rights and remedies of creditors, such as the Federal Bankruptcy Code, and laws,
if any, which may be enacted by federal or state legislatures extending the time
for payment of principal or interest, or both, or imposing other constraints
upon enforcement of such obligations or upon the ability of municipalities to
levy taxes. There is also the possibility that as a result of litigation or
other conditions, the power or ability of any one or more issuers to pay, when
due, principal of and interest on its, or their, Municipal Securities may be
materially adversely affected.

                  Among other instruments, the Tax Exempt Fund may purchase
short-term Tax Anticipation Notes, Bond Anticipation Notes, Revenue Anticipation
Notes and other forms of short-term loans. Such notes are issued with a
short-term maturity in anticipation of the receipt of tax funds, the proceeds of
bond placements or other revenues.

                               INVESTMENT POLICIES

                  The following policies supplement the descriptions of each
Fund's investment objective and policies in the Prospectus.

Additional Information on Investment Practices

                  Variable Rate Master Demand Notes. Variable rate master demand
notes held by a Fund may have maturities of more than thirteen months, provided:
(i) the Fund is entitled to payment of principal and accrued interest upon not
more than seven days' notice and (ii) the rate of interest on such notes is
adjusted automatically at periodic intervals which may extend up to thirteen
months. In determining the Fund's average weighted portfolio maturity and
whether a variable rate master demand note has a remaining maturity of thirteen
months or less, each note will be deemed by the Fund to have a maturity equal to
the longer of the period remaining until its next interest rate adjustment or
the period remaining until the principal amount owed can be recovered through
demand. In determining whether an unrated variable rate master demand note is of
comparable quality at the time of purchase to instruments rated "high quality"
by any major rating service or when purchasing variable rate master demand
notes, the Fund's investment adviser and sub-investment adviser will consider
the earning power, cash flow and other liquidity ratios of the issuer of the
note and will continuously monitor its financial condition. In addition, when
necessary to ensure that a note is of "high quality," the Fund will require that
the issuer's obligation to pay the principal of the note be backed by an
unconditional bank letter of line of credit, guarantee or commitment to lend.

                  In the event an issuer of a variable rate master demand note
defaults on its payment obligation, a Fund might be unable to dispose of the
note because of the absence of a secondary market and might, for this or other
reasons, suffer a loss to the extent of the default. However, the Fund will
invest in such instruments only where its investment adviser and 


                                       3
<PAGE>   35

sub-investment adviser believe that the risk of such loss is minimal. In
determining average weighted portfolio maturity, a variable rate master demand
note will be deemed to have a maturity equal to the longer of the period
remaining to the next interest rate adjustment or the demand note period.

                  When-Issued Securities. As stated in the Prospectus, a Fund
may purchase Municipal Securities or portfolio securities, as the case may be,
on a "when-issued" basis (i.e., for delivery beyond the normal settlement date
at a stated price and yield). When the Fund agrees to purchase when-issued
securities, its custodian will set aside cash or liquid securities in a
segregated account equal to the amount of the commitment. Normally, the
custodian will set aside portfolio securities to satisfy a purchase commitment,
and in such a case the Fund may be required subsequently to place additional
assets in the segregated account in order to ensure that the value of the
account remains equal to the amount of the Fund's commitment. It may be expected
that the Fund's net assets will fluctuate to a greater degree when it sets aside
portfolio securities to cover such purchase commitments than when it sets aside
cash. Because the Fund will set aside cash and liquid assets to satisfy its
purchase commitments in the manner described, the Fund's liquidity and ability
to manage its portfolio might be affected in the event its commitments to
purchase when-issued securities ever exceeded 25% of the value of its assets.

                  When a Fund engages in when-issued transactions, it relies on
the seller to consummate the trade. Failure of the seller to do so may result in
the Fund's incurring a loss or missing an opportunity to obtain a price
considered to be advantageous.

                  Reverse Repurchase Agreements and Borrowings. A Fund may
borrow funds for temporary purposes and not for leverage by agreeing to sell
portfolio securities to financial institutions such as banks and broker-dealers
and to repurchase them at a mutually agreed-upon date and price. At the time the
Fund enters into such an arrangement (a "reverse repurchase agreement"), it will
place in a segregated custodial account cash or liquid securities having a value
equal to the repurchase price (including accrued interest) and will subsequently
monitor the account to ensure that such equivalent value is maintained. Reverse
repurchase agreements involve the risk that the market value of the securities
sold by the Fund may decline below the repurchase price of those securities.
Reverse repurchase agreements are considered to be borrowings by the Fund under
the Investment Company Act of 1940, as amended (the "1940 Act").

                  Repurchase Agreements (Money Market Fund only). The seller
under a repurchase agreement will be required to maintain the value of the
securities subject to the agreement at not less than the repurchase price
(including accrued interest). Securities subject to repurchase agreements will
be held by the Fund's custodian or in the Federal Reserve/Treasury book-entry
system or another authorized securities depository.

                  Stand-By Commitment Agreements (Tax Exempt Fund only). The
Fund may acquire "stand-by commitments" with respect to Municipal Securities
held in its portfolio. Under a stand-by commitment, a dealer agrees to purchase
at the Fund's option specified 



                                       4
<PAGE>   36

Municipal Securities at a specified price. Stand-by commitments acquired by the
Fund may also be referred to as "put" options. The Fund's right to exercise
stand-by commitments is unconditional and unqualified. A stand-by commitment is
not transferable by the Fund, although the Fund can sell the underlying
securities to a third party at any time.

                  The principal risk of a stand-by commitment is that the writer
of a commitment may default on its obligation to repurchase the securities
acquired with it. The Fund intends to enter into stand-by commitments only with
brokers, dealers and banks that, in the opinion of Warburg Pincus Asset
Management, Inc., each Fund's investment adviser ("Warburg"), present minimal
credit risks. In evaluating the creditworthiness of the issuer of a stand-by
commitment, Warburg will periodically review relevant financial information
concerning the issuer's assets, liabilities and contingent claims.

                  The amount payable to the Fund upon its exercise of a stand-by
commitment is normally (i) the Fund's acquisition cost of the Municipal
Securities (excluding any accrued interest which the Fund paid on their
acquisition), less any amortized market premium or plus any amortized market or
original issue discount during the period the Fund owned the securities, plus
(ii) all interest accrued on the securities since the last interest payment date
during that period.

                  The Fund expects that stand-by commitments will generally be
available without the payment of any direct or indirect consideration. However,
if necessary or advisable, the Fund may pay for a stand-by commitment either
separately in cash or by paying a higher price for portfolio securities which
are acquired subject to the commitment (thus reducing the yield to maturity
otherwise available for the same securities). The total amount paid in either
manner for outstanding stand-by commitments held by the Fund will not exceed 1/2
of 1% of the value of its total assets calculated immediately after each
stand-by commitment is acquired.

                  The Fund would acquire stand-by commitments solely to
facilitate portfolio liquidity and does not intend to exercise its rights
thereunder for trading purposes. The acquisition of a stand-by commitment would
not affect the valuation or assumed maturity of the underlying Municipal
Securities which, as noted, would continue to be valued in accordance with the
amortized cost method. Stand-by commitments acquired by the Fund would be valued
at zero in determining net asset value. Where the Fund paid any consideration
directly or indirectly for a stand-by commitment, its cost would be reflected as
unrealized depreciation for the period during which the commitment was held by
the Fund. Stand-by commitments would not affect the average weighted maturity of
the Fund's portfolio.

                  The Internal Revenue Service has issued a revenue ruling to
the effect that a registered investment company will be treated for federal
income tax purposes as the owner of the Municipal Securities acquired subject to
a stand-by commitment and the interest on the Municipal Securities will be
tax-exempt to the Fund.

                  Third Party Puts (Tax Exempt Fund only). The Fund may purchase
long-term fixed rate bonds that have been coupled with an option granted by a
third party financial institution allowing the Fund at specified intervals to
tender (or "put") the bonds to the 


                                       5
<PAGE>   37

institution and receive the face value thereof (plus accrued interest). These
third party puts are available in several different forms, may be represented by
custodial receipts or trust certificates and may be combined with other features
such as interest rate swaps. The Fund receives a short-term rate of interest
(which is periodically reset), and the interest rate differential between that
rate and the fixed rate on the bond is retained by the financial institution.
The financial institution granting the option does not provide credit
enhancement, and in the event that there is a default in the payment of
principal or interest, or downgrading of a bond to below investment grade, or a
loss of the bond's tax-exempt status, the put option will terminate
automatically, the risk to the Fund will be that of holding such a long-term
bond and the dollar-weighted average maturity of the Fund's portfolio would be
adversely affected.

                  These bonds coupled with puts may present the same tax issues
as are associated with stand-by commitments. As with any stand-by commitment,
the Fund intends to take the position that it is the owner of any municipal
obligation acquired subject to a third party put, and that tax-exempt interest
earned with respect to such municipal obligations will be tax-exempt in its
hands. There is no assurance that the Internal Revenue Service will agree with
such position in any particular case. Additionally, the federal income tax
treatment of certain other aspects of these investments, including the treatment
of tender fees and swap payments, in relation to various regulated investment
company tax provisions is unclear. However, Warburg intends to manage the Fund
in a manner designed to minimize any adverse impact from these investments.

                  Taxable Investments (Tax Exempt Fund only). Because the Fund's
purpose is to provide income excluded from gross income for federal income tax
purposes, the Fund generally will invest in taxable obligations only if and when
the investment adviser believes it would be in the best interests of the Fund's
investors to do so. Situations in which the Fund may invest up to 20% of its
total assets in taxable securities include: (i) pending investment of proceeds
of sales of Fund shares or the sale of its portfolio securities or (ii) when the
Fund requires highly liquid securities in order to meet anticipated redemptions.
The Fund may temporarily invest more than 20% of its total assets in taxable
securities to maintain a "defensive" posture when the Fund's investment adviser
determines that it is advisable to do so because of adverse market conditions
affecting the market for Municipal Securities generally.

                  Among the taxable investments in which the Fund may invest are
repurchase agreements and time deposits maturing in not more than seven days.
The Fund may agree to purchase money market instruments from financial
institutions such as banks and broker-dealers subject to the seller's agreement
to repurchase them at an agreed-upon date and price ("repurchase agreements").
The seller under a repurchase agreement will be required to maintain the value
of the securities subject to the agreement at not less than the repurchase price
(including accrued interest). Securities subject to repurchase agreements will
be held by the Fund's custodian or in the Federal Reserve/Treasury book-entry
system or another authorized securities depository.

Other Investment Limitations

                  Money Market Fund. The investment limitations numbered 1
through 6 may not be changed without the affirmative vote of the holders of a
majority of the Money Market Fund's outstanding shares. Such majority is defined
as the lesser of (i) 67% or more of the shares present at a meeting, if the
holders of more than 50% of the outstanding shares of the Fund are present or
represented by proxy, or (ii) more than 50% of the outstanding shares.
Investment limitations 7 and 12 may be changed by a vote of the Fund's Board of
Directors (the "Board") at any time.

                  The Money Market Fund may not:

                  1.       Borrow money, issue senior securities or enter into
reverse repurchase agreements except for temporary or emergency purposes and not
for leveraging, and then in amounts not in excess of 10% of the value of the
Fund's assets at the time of such borrowing; or mortgage, pledge or hypothecate
any assets except in connection with any such borrowing and in amounts not in
excess of the lesser of the dollar amounts borrowed or 10% of the value of the
Fund's assets at the time of such borrowing. The Fund does not currently intend
to enter into reverse repurchase agreements in amounts in excess of 5% of its
assets at the time the agreement is entered into. Whenever borrowings exceed 5%
of the value of the Fund's total assets, the Fund will not make any additional
investments.

                  2.       Purchase or sell real estate, real estate investment
trust securities, commodities or commodity contracts, or invest in oil, gas or
mineral exploration or development programs, except that the Fund may purchase
commercial paper issued by companies that invest in real estate or interests
therein.

                  3.       Purchase the securities of any issuer if as a result
more than 5% of the value of the Fund's assets would be invested in the
securities of such issuer, except that this 5% limitation does not apply to
securities issued or guaranteed by the United States government, its agencies or
instrumentalities, and except that up to 25% of the value of the Fund's assets
may be invested without regard to this 5% limitation.

                  4.       Purchase any securities which would cause more than
25% of the value of the Fund's total assets at the time of purchase to be
invested in the securities of issuers conducting their principal business
activities in the same industry; provided that there shall be no limit on the
purchase of obligations issued or guaranteed by the United States, any state,
territory or possession of the United States, the District of Columbia or any of
their authorities, agencies, instrumentalities or political sub-divisions or
certificates of deposit, time deposits, savings deposits and bankers'
acceptances.

                  5.       Make loans except that the Fund may purchase or hold
debt obligations in accordance with its investment objective, policies and
limitations and enter into repurchase agreements.

<PAGE>   39

                  6.       Underwrite any issue of securities except to the
extent that the purchase of debt obligations directly from the issuer thereof in
accordance with the Fund's investment objective, policies and limitations may be
deemed to be underwriting.

                  7.       Purchase securities on margin, make short sales of 
securities or maintain a short position.

                  8.       Write or sell puts, calls, straddles, spreads or 
combinations thereof.

                  9.       Invest in common stocks, preferred stocks, warrants,
other equity securities, corporate bonds or indentures, state bonds, municipal
bonds or industrial revenue bonds.

                  10.      Purchase securities of other investment companies
except in connection with a merger, consolidation, acquisition or
reorganization.

   
                  11.      Invest more than 10% of the value of the Fund's net
assets in securities which may be illiquid because of legal or contractual
restrictions on resale or securities for which there are no readily available
market quotations. For purposes of this limitation, repurchase agreements with
maturities greater than seven days after notice by the Fund, variable rate
master demand notes providing for settlement upon maturities longer than seven
days and savings accounts which require more than seven days' notice prior to
withdrawal shall be considered illiquid securities.
    

                  12.      Invest in oil, gas or mineral leases.

   
                  If a percentage restriction (other than the percentage
limitation set forth in No. 1 and No. 11 above) is adhered to at the time of an
investment, a later increase or decrease in the percentage of assets resulting
from a change in the values of portfolio securities or in the amount of the
Fund's assets will not constitute a violation of such restriction.
    

                  Tax Exempt Fund. The investment limitations numbered 1 through
6 may not be changed without the affirmative vote of the holders of a majority
of the Tax Exempt Fund's outstanding shares. Such majority is defined as the
lesser of (i) 67% or more of the shares present at a meeting, if the holders of
more than 50% of the outstanding shares of the Fund are present or represented
by proxy, or (ii) more than 50% of the outstanding shares. Investment
limitations 7 and 11 may be changed by a vote of the Fund's Board of Directors
at any time.

                  The Tax Exempt Fund may not:

                  1.        Invest less than 80% of its assets in securities the
interest on which is exempt from federal income tax, except during temporary
defensive periods or under unusual market conditions, as determined by the
Fund's investment adviser.

                  2.        Borrow money, issue senior securities or enter into
reverse repurchase agreements except for temporary or emergency purposes, and
not for leveraging, and then in 

                                       8
<PAGE>   40
amounts not in excess of 10% of the value of the Fund's assets at the time of
such borrowing; or mortgage, pledge or hypothecate any assets except in
connection with any such borrowing and in amounts not in excess of the lesser of
the dollar amounts borrowed or 10% of the value of the Fund's assets at the time
of such borrowing. The Fund does not currently intend to enter into reverse
repurchase agreements in amounts in excess of 5% of its assets at the time the
agreement is entered into. Whenever borrowings exceed 5% of the value of the
Fund's total assets, the Fund will not make any additional investments.

                  3.        Purchase any securities which would cause more than
25% of the value of the Fund's total assets at the time of purchase to be
invested in the securities of issuers conducting their principal business
activities in the same industry; provided that there shall be no limit on the
purchase of (i) obligations issued by the United States, any state, territory or
possession of the United States, the District of Columbia or any of their
authorities, agencies, instrumentalities or political sub-divisions, (ii)
certificates of deposit issued by United States branches of United States banks
or (iii) Municipal Securities the interest on which is paid solely from revenues
of economically related projects. For purposes of this restriction, private
activity securities ultimately payable by companies within the same industry are
treated as if they were issued by issuers in the same industry.

                  4.        Make loans except that the Fund may purchase or hold
debt obligations and enter into repurchase agreements in accordance with its
investment objective, policies and limitations.

                  5.        Underwrite any issue of securities except to the
extent that the purchase of debt obligations directly from the issuer thereof in
accordance with the Fund's investment objective, policies and limitations may be
deemed to be underwriting.

                  6.        Purchase or sell real estate, real estate investment
trust securities, commodities or commodity contracts, or invest in oil, gas or
mineral exploration or development programs, except that the Fund may invest in
debt obligations secured by real estate, mortgages or interests therein.

                  7.        Purchase securities on margin, make short sales of 
securities or maintain short positions.

                  8.        Write or sell puts, calls, straddles, spreads or
combinations thereof, except that the Fund may acquire stand-by commitments.

                  9.        Purchase securities of other investment companies 
except in connection with a merger, consolidation, acquisition or
reorganization.

   
                  10.       Invest more than 10% of the value of the Fund's
net assets in securities which may be illiquid because of legal or contractual
restrictions on resale or securities for which there are not readily available
market quotations. For purposes of this limitation, repurchase agreements with
maturities greater than seven days and variable rate master demand 
    


                                       9
<PAGE>   41

notes providing for settlement upon more than seven days notice by the Fund and
time deposits maturing in more than seven calendar days shall be considered
illiquid securities.

                  11.       Invest in oil, gas or mineral leases.

   
                  If a percentage restriction (other than the percentage
limitation set forth in No. 2 and No. 10 above) is adhered to at the time of an
investment, a later increase or decrease in the percentage of assets resulting
from a change in the values of portfolio securities or in the amount of the
Fund's assets will not constitute a violation of such restriction.
    

Portfolio Valuation

                  Each Fund's securities are valued on the basis of amortized
cost. Under this method, a Fund values a portfolio security at cost on the date
of purchase and thereafter assumes a constant value of the security for purposes
of determining net asset value, which normally does not change in response to
fluctuating interest rates. Although the amortized cost method seems to provide
certainty in portfolio valuation, it may result in periods during which values,
as determined by amortized cost, are higher or lower than the amount the Fund
would receive if it sold the securities. In connection with amortized cost
valuation, the Board has established procedures that are intended to stabilize
the Fund's net asset value per share for purposes of sales and redemptions at
$1.00. These procedures include review by the Board, at such intervals as it
deems appropriate, to determine the extent, if any, to which the Fund's net
asset value per share calculated by using available market quotations deviates
from $1.00 per share. In the event such deviation exceeds 1/2 of 1%, the Board
will promptly consider what action, if any, should be initiated. If the Board
believes that the amount of any deviations from the Fund's $1.00 amortized cost
price per share may result in material dilution or other unfair results to
investors or existing shareholders, it will take such steps as it considers
appropriate to eliminate or reduce to the extent reasonably practicable any such
dilution or unfair results. These steps may include selling portfolio
instruments prior to maturity; shortening the Fund's average portfolio maturity;
withholding or reducing dividends; redeeming shares in kind; reducing the number
of the Fund's outstanding shares without monetary consideration; or utilizing a
net asset value per share determined by using available market quotations.

Portfolio Transactions

                  Warburg is responsible for establishing, reviewing, and, where
necessary, modifying a Fund's investment program to achieve its investment
objective. BlackRock Institutional Management Corporation ("BIMC") generally
will select specific portfolio investments and effect transactions for each
Fund. Purchases and sales of portfolio securities are usually principal
transactions without brokerage commissions effected directly with the issuer or
with dealers who specialize in money market instruments. BIMC seeks to obtain
the best net price and the most favorable execution of orders. To the extent
that the execution and price offered by more than one dealer are comparable,
BIMC may, in its discretion, effect 



                                       10
<PAGE>   42

transactions in portfolio securities with dealers who provide the relevant Fund
with research advice or other services.

                  Investment decisions for a Fund concerning specific portfolio
securities are made independently from those for other clients advised by BIMC.
Such other investment clients may invest in the same securities as the Fund.
When purchases or sales of the same security are made at substantially the same
time on behalf of such other clients, transactions are averaged as to price, and
available investments allocated as to amount, in a manner which BIMC believes to
be equitable to each client, including the Fund. In some instances, this
investment procedure may adversely affect the price paid or received by the Fund
or the size of the position obtained or sold for the Fund. To the extent
permitted by law, BIMC may aggregate the securities to be sold or purchased for
each Fund with those to be sold or purchased for such other investment clients
in order to obtain best execution.

                  In no instance will portfolio securities be purchased from or
sold to Warburg, BIMC, PNC Bank, National Association ("PNC") or Counsellors
Securities Inc. ("Counsellors Securities") or any affiliated person of such
companies, except pursuant to an exemption received from the Securities and
Exchange Commission (the "SEC").

                  The Tax Exempt Fund may participate, if and when practicable,
in bidding for the purchase of Municipal Securities directly from an issuer for
its portfolio in order to take advantage of the lower purchase price available
to members of such a group. The Fund will engage in this practice, however, only
when Warburg or BIMC, in their sole discretion, believes such practice to be
otherwise in the Fund's interest.

                  Each Fund does not intend to seek profits through short-term
trading. A Fund's annual portfolio turnover will be relatively high but is not
expected to have a material effect on its net income. Each Fund's turnover is
expected to be zero for regulatory reporting purposes.

Investment Advisers, Sub-Investment Adviser and Administrator
and Co-Administrator

                  Warburg serves as investment to the Money Market Fund and Tax
Exempt Fund, BIMC serves as sub-investment adviser and administrator to each
Fund, and Counsellors Funds Service, Inc. ("Counsellors Service") serves as
co-administrator to the Funds pursuant to written agreements (the "Advisory
Agreement," the "Sub-Advisory Agreements" and the "Co-Administration Agreement,"
respectively, and collectively, the "Agreements"). The services provided by and
the fees payable by a Fund to Warburg, BIMC and Counsellors Service under the
respective Agreements are described in the Prospectus.

Banking Laws

                  Banking laws and regulations presently (i) prohibit a bank
holding company registered under the Federal Bank Holding Company Act of 1956
(the "Holding Company Act") or any bank or non-bank affiliate thereof from
sponsoring, organizing, controlling, or distributing the shares of a registered,
open-end investment company continuously engaged in the issuance of its shares,
but (ii) do not prohibit such a holding company or affiliate from acting as
investment adviser, transfer agent or custodian to such an investment company.
PNC and BIMC are subject to such banking laws and regulations.

                  BIMC, PNC and the Funds have been advised by Messrs. Ballard,
Spahr, Andrews & Ingersoll that BIMC and PNC may perform the services for the
Fund contemplated by their respective agreements with the Fund and the
Prospectus without violation of applicable banking laws or regulations. Such
counsel have pointed out, however, that future changes in legal requirements
relating to the permissible activities of banks and their affiliates, as well as
future interpretations of present requirements, could prevent one or more of
them from continuing to perform services for the Fund. If BIMC or PNC were
prohibited from providing services to the Fund, the Board would select another
qualified firm. Any new investment or sub-investment advisory agreement would be
subject to shareholder approval.

Custodian and Transfer Agent

                  PNC is custodian of each Fund's assets pursuant to a custodian
agreement (the "Custodian Agreement"). Under the Custodian Agreement, PNC (i)
maintains a separate account or accounts in the name of the Fund, (ii) holds and
transfers portfolio securities on account of the Fund, (iii) makes receipts and
disbursements of money on behalf of the Fund, (iv) collects and receives all
income and other payments and distributions on account of the Fund's portfolio
securities and (v) makes periodic reports to the Board concerning the Fund's
custodial arrangements. PNC is authorized to select one or more banks or trust
companies to serve as sub-custodian on behalf of a Fund, provided that PNC
remains responsible for the performance of all its duties under the Custodian
Agreement and holds the Fund harmless from the acts and omissions of any
sub-custodian. PNC is an indirect wholly owned subsidiary of PNC Bank Corp., and
its principal business address is 1600 Market Street, Philadelphia, Pennsylvania
19103.

                  State Street Bank and Trust Company ("State Street") has
agreed to serve as each Fund's shareholder servicing, transfer and dividend
disbursing agent pursuant to a Transfer Agency and Service Agreement, under
which State Street (i) issues and redeems shares of the Fund, (ii) addresses and
mails all communications by the Fund to record owners of the Fund shares,
including reports to shareholders, dividend and distribution notices and proxy
material for its meetings of shareholders, (iii) maintains shareholder accounts
and, if requested, sub-accounts, and (iv) makes periodic reports to the Board
concerning the transfer agent's operations with respect to the Fund. State
Street has delegated to Boston Financial Data Services, Inc. ("BFDS"), an
affiliated company, responsibility for most shareholder servicing functions. The
principal business address of State Street is 225 Franklin Street, Boston,
Massachusetts 02110. BFDS's principal business address is 2 Heritage Drive,
Boston, Massachusetts 02171.

Organization of the Funds

                  The Funds are incorporated in Maryland. See the Prospectus,
"General Information." All shareholders of a Fund, upon liquidation, will
participate ratably in the Fund's net assets. Shares do not have cumulative
voting rights, which means that holders of more than 50% of the shares voting
for the election of Directors can elect all Directors. Shares are transferable
but have no preemptive, conversion or subscription rights.

Distribution and Shareholder Servicing

   
                  Common Shares. Each Fund has entered into a Shareholder
Servicing and Distribution Plan (the "12b-1 Plan"), pursuant to Rule 12b-1 under
the 1940 Act, pursuant to which a Fund will pay Counsellors Securities, in
consideration for Services (as defined below), a fee calculated at an annual
rate of .25% of the average daily net assets of the Common Shares of the Fund.
Services performed by Counsellors Securities include (i) the sale of the Common
Shares, as set forth in the 12b-1 Plan ("Selling Services"), (ii) ongoing
servicing and/or maintenance of the accounts of Common Shareholders of the Fund,
as set forth in the 12b-1 Plan ("Shareholder Services"), and (iii) sub-transfer
agency services, subaccounting services or administrative services related to
the sale of the Common Shares, as set forth in the 12b-1 Plan ("Administrative
Services" and collectively with Selling Services and Administrative Services,
"Services") including, without limitation, (a) payments reflecting an allocation
of overhead and other office expenses of Counsellors Securities related to
providing Services; (b) payments made to, and reimbursement of expenses of,
persons who provide support services in connection with the distribution of the
Common Shares including, but not limited to, office space and equipment,
telephone facilities, answering routine inquiries regarding the Fund, and
providing any other Shareholder Services; (c) payments made to compensate
selected dealers or other authorized persons for providing any Services; (d)
costs relating to the formulation and implementation of marketing and
promotional activities for the Common Shares, including, but not limited to,
direct mail promotions and television, radio, newspaper, magazine and other mass
media advertising, and related travel and entertainment expenses; (e) costs of
printing and distributing prospectuses, statements of additional information and
reports of the Fund to prospective shareholders of the Fund; (f) costs
    

                                       16
<PAGE>   48
   
involved in obtaining whatever information, analyses and reports with respect
to marketing and promotional activities that the Fund may, from time to time,
deem advisable; and (g) costs and expenses relating to the Fund's participation
in the Northwest Airlines WorldPerks(TM) program.
    

                  Pursuant to the 12b-1 Plan, Counsellors Securities will
provide the Fund's Board with periodic reports of amounts expended under the
12b-1 Plan and the purpose for which the expenditures were made.

                  Advisor Shares. Each Fund may, in the future, enter into
agreements ("Agreements") with institutional shareholders of record,
broker-dealers, financial institutions, depository institutions, retirement
plans and financial intermediaries ("Institutions") to provide certain
distribution, shareholder servicing, administrative and/or accounting services
for their clients or customers (or participants in the case of retirement plans)
("Customers") who are beneficial owners of Advisor Shares. Agreements will be
governed by a distribution plan (the "Distribution Plan") pursuant to Rule 12b-1
under the 1940 Act. The Distribution Plan requires the Board, at least
quarterly, to receive and review written reports of amounts expended under the
Distribution Plan and the purpose for which such expenditures were made.

                  An Institution with which a Fund has entered into an Agreement
with respect to its Advisor Shares may charge a Customer one or more of the
following types of fees, as agreed upon by the Institution and the Customer,
with respect to the cash management or other services provided by the
Institution: (i) account fees (a fixed amount per month or per year); (ii)
transaction fees (a fixed amount per transaction processed); (iii) compensation
balance requirements (a minimum dollar amount a Customer must maintain in order
to obtain the services offered); or (iv) account maintenance fees (a periodic
charge based upon the percentage of assets in the account or of the dividend
paid on those assets). Services provided by an Institution to Customers are in
addition to, and not duplicative of, the services to be provided under the
Fund's co-administration and distribution and shareholder servicing
arrangements. A Customer of an Institution should read the Prospectus and this
Statement of Additional Information in conjunction with the Agreement and other
literature describing the services and related fees that would be provided by
the Institution to its Customers prior to any purchase of Fund shares.
Prospectuses are available from the Fund's distributor upon request. No
preference will be shown in the selection of Fund investments for the
instruments of Institutions.

                  General. The Distribution Plan and the 12b-1 Plan will
continue in effect for so long as their continuance is specifically approved at
least annually by the Board, including a majority of the Directors who are not
interested persons of the Fund and who have no direct or indirect financial
interest in the operation of the Distribution Plans or the 12b-1 Plans, as the
case may be ("Independent Directors"). Any material amendment of the
Distribution Plan or 12b-1 Plan would require the approval of the Board in the
same manner. Neither the Distribution Plan nor the 12b-1 Plan may be amended to
increase materially the amount to be spent thereunder without shareholder
approval of the relevant class of shares. The Distribution Plan or 12b-1 Plan
may be terminated at any time, without penalty, by vote of a majority of the
Independent Directors or by a vote of a majority of the outstanding voting
securities of the relevant class of shares of the Fund.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

                  Information on how to purchase and redeem Fund shares and how
such shares are priced is included in the Prospectus.

                  Under the 1940 Act, each Fund may suspend the right of
redemption or postpone the date of payment upon redemption for any period during
which The New York Stock Exchange, Inc. (the "NYSE") is closed, other than
customary weekend and holiday closings, or during which trading on the NYSE is
restricted, or during which (as determined by the SEC by rule or regulation) an
emergency exists as a result of which disposal or fair valuation of portfolio
securities is not reasonably practicable, or for such other periods as the SEC
may permit. (A Fund may also suspend or postpone the recordation of an exchange
of its shares upon the occurrence of any of the foregoing conditions.)

                  If the Board determines that conditions exist which make
payment of redemption proceeds wholly in cash unwise or undesirable, a Fund may
make payment wholly or partly in securities or other investment instruments
which may not constitute securities as such term is defined in the applicable
securities laws. If a redemption is paid wholly or partly in securities or other
property, a shareholder would incur transaction costs in disposing of the
redemption proceeds. The Fund will comply with Rule 18f-1 promulgated under the
1940 Act with respect to redemptions in kind.

                  Automatic Cash Withdrawal Plan. An automatic cash withdrawal
plan (the "Plan") is available to shareholders who wish to receive specific
amounts of cash periodically. Withdrawals may be made under the Plan by
redeeming as many shares of a Fund as may be necessary to cover the stipulated
withdrawal payment. To the extent that withdrawals exceed dividends,
distributions and appreciation of a shareholder's investment in the Fund, there
will be a reduction in the value of the shareholder's investment and continued
withdrawal payments may reduce the shareholder's investment and ultimately
exhaust it. Withdrawal payments should not be considered as income from
investment in the Fund. All dividends and distributions on shares in the Plan
are automatically reinvested at net asset value in additional shares of the
Fund.

                               EXCHANGE PRIVILEGE

                  An exchange privilege with certain other funds advised by
Warburg is available to investors in a Fund. The funds into which exchanges of
Common Shares currently can be made are listed in the Common Share Prospectus.
Exchanges may also be made between certain Warburg Pincus Advisor Funds.

                  The exchange privilege enables shareholders to acquire shares
in a fund with a different investment objective when they believe that a shift
between funds is an appropriate investment decision. Subject to the restrictions
on exchange purchases contained in the Prospectus and any other applicable
restrictions, this privilege is available to shareholders residing in any state
in which the Common Shares or Advisor Shares being acquired, as relevant, may
legally be sold. Prior to any exchange, the investor should obtain and review a



                                       18
<PAGE>   50

copy of the current prospectus of the relevant class of each fund into which an
exchange is being considered. Shareholders may obtain a prospectus of the
relevant class of the fund into which they are contemplating an exchange from
Counsellors Securities.

                  Subject to the restrictions described above, upon receipt of
proper instructions and all necessary supporting documents, shares submitted for
exchange are redeemed at the then-current net asset value of the relevant class
and the proceeds are invested on the same day, at a price as described above, in
shares of the relevant class of the fund being acquired. The exchange privilege
may be modified or terminated at any time upon 30 days' notice to shareholders.

                     ADDITIONAL INFORMATION CONCERNING TAXES

                  The discussion set out below of tax considerations generally
affecting the Fund and its shareholders is intended to be only a summary and is
not intended as a substitute for careful tax planning by prospective
shareholders. Shareholders are advised to consult their own tax advisers with
respect to the particular tax consequences to them of an investment in the Fund.

                  As described above and in the Fund's Prospectus, the Tax
Exempt Fund is designed to provide investors with current income which is
excluded from gross income for federal income tax purposes. The Fund is not
intended to constitute a balanced investment program and is not designed for
investors seeking capital gains or maximum tax-exempt income irrespective of
fluctuations in principal. Investment in the Fund would not be suitable for
tax-exempt institutions, individual retirement plans, employee benefit plans and
individual retirement accounts since such investors would not gain any
additional tax benefit from the receipt of tax-exempt income.

                  Each Fund intends to continue to qualify as a "regulated
investment company" under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code"). If it qualifies as a regulated investment company, a Fund
will pay no federal income taxes on its taxable net investment income (that is,
taxable income other than net realized capital gains) and its net realized
capital gains that are distributed to shareholders. To qualify under Subchapter
M, each Fund must, among other things: (i) distribute to its shareholders at
least the sum of 90% of its taxable net investment income (for this purpose
consisting of taxable net investment income and net realized short-term capital
gains) plus 90% of its net tax-exempt interest income; (ii) derive at least 90%
of its gross income from dividends, interest, payments with respect to loans of
securities, gains from the sale or other disposition of securities, or other
income (including, but not limited to, gains from options, futures, and forward
contracts) derived with respect to the Fund's business of investing in
securities; and (iii) diversify its holdings so that, at the end of each fiscal
quarter of the Fund (a) at least 50% of the market value of the Fund's assets is
represented by cash, U.S. government securities and other securities, with those
other securities limited, with respect to any one issuer, to an amount no
greater in value than 5% of the Fund's total assets and to not more than 10% of
the outstanding voting securities of the issuer, and (b) not more than 25% of
the market value of

                                       19
<PAGE>   51
the Fund's assets is invested in the securities of any one issuer (other than
U.S. government securities or securities of other regulated investment
companies) or of two or more issuers that the Fund controls and that are
determined to be in the same or similar trades or businesses or related trades
or businesses. As a regulated investment company, the Fund will be subject to a
4% non-deductible excise tax measured with respect to certain undistributed
amounts of ordinary income and capital gain required to be but not distributed
under a prescribed formula. The formula requires payment to shareholders during
a calendar year of distributions representing at least 98% of the Fund's taxable
ordinary income for the calendar year and at least 98% of the excess of its
capital gains over capital losses realized during the one-year period ending
December 31 during such year, together with any undistributed, untaxed amounts
of ordinary income and capital gains from the previous calendar year. The Funds
expect to pay the dividends and make the distributions necessary to avoid the
application of this excise tax.

                  Although each Fund expects to be relieved of all or
substantially all federal income taxes, depending upon the extent of its
activities in states and localities in which its offices are maintained, in
which its agents or independent contractors are located or in which it is
otherwise deemed to be conducting business, that portion of a Fund's income
which is treated as earned in any such state or locality could be subject to
state and local tax. Any taxes paid by the Fund would reduce the amount of
income and gains available for distribution to shareholders.

                  Investors in the Money Market Fund should be aware that it is
possible that some portion of the Fund's income from investments in obligations
of foreign banks could become subject to foreign taxes.

                  Because the Tax Exempt Fund will distribute exempt interest
dividends, interest on indebtedness incurred by a shareholder to purchase or
carry Fund shares is not deductible for federal income tax purposes. In
addition, the Code may require a shareholder, if he or she receives exempt
interest dividends, to treat as taxable income a portion of certain otherwise
non-taxable social security and railroad retirement benefit payments.
Furthermore, that portion of any dividend paid by the Fund which represents
income derived from private activity securities held by the Fund may not retain
its tax-exempt status in the hands of a shareholder who is a "substantial user"
of a facility financed by such bonds, or a "related person" thereof. Moreover,
as noted in the Prospectus, (i) some of the Fund's dividends may be a tax
preference item, or a component of an adjustment item, for purposes of the
federal individual and corporate alternative minimum taxes and (ii) the receipt
of Fund dividends and distributions may affect a corporate shareholder's federal
"environmental" tax liability if that tax is reinstated as proposed by President
Clinton. In addition, the receipt of Fund dividends and distributions may affect
a foreign corporate shareholder's federal "branch profits" tax liability and a
Subchapter S corporation shareholder's federal "excess net passive income" tax
liability. Shareholders should consult their own tax advisers as to whether they
(i) may be "substantial users" with respect to a facility or "related" to such
users within the meaning of the Code and (ii) are subject to a federal
alternative minimum tax, the federal environmental tax, the federal "branch
profits" tax, or the federal "excess net passive income" tax.

                                       20
<PAGE>   52

                  While each Fund does not expect to realize net long-term
capital gains, any such realized gains will be distributed as described in the
Prospectus. Such distributions ("capital gain dividends") will be taxable to
shareholders as long-term capital gains, regardless of how long a shareholder
has held Fund shares, and will be designated as capital gain dividends in a
written notice mailed by a Fund to shareholders after the close of the Fund's
taxable year. Gain or loss, if any, recognized on the sale or other disposition
of shares of the Fund will be taxed as capital gain or loss if the shares are
capital assets in the shareholder's hands. Generally, a shareholder's gain or
loss will be a long-term gain or loss if the shares have been held for more than
one year. If a shareholder sells or otherwise disposes of a share of the Fund
before holding it for more than six months, any loss on the sale or other
disposition of such share shall be treated as a long-term capital loss to the
extent of any capital gain dividends received by the shareholder with respect to
such share.

                  A shareholder of a Fund receiving dividends or distributions
in additional shares should be treated for federal income tax purposes as
receiving a distribution in an amount equal to the amount of money that a
shareholder receiving cash dividends or distributions receives, and should have
a cost basis in the shares received equal to that amount.

                  Each shareholder of the Money Market Fund will receive an
annual statement as to the federal income tax status of his dividends and
distributions from the Fund for the prior calendar year. Furthermore,
shareholders will also receive, if appropriate, various written notices after
the close of the Fund's taxable year regarding the federal income tax status of
certain dividends and distributions that were paid (or that are treated as
having been paid) by the Fund to its shareholders during the preceding year.

                  Each shareholder of the Tax Exempt Fund will receive an annual
statement as to the federal personal income tax status of his dividends and
distributions from the Fund for the prior calendar year. Furthermore,
shareholders will also receive, if appropriate, various written notices after
the close of the Fund's taxable year regarding the federal income tax status of
certain dividends and distributions that were paid (or that are treated as
having been paid) by the Fund to its shareholders during the preceding year.
Shareholders should consult their tax advisers as to any other state and local
taxes that may apply to the Fund's dividends and distributions. The dollar
amount of dividends excluded from federal income taxation and the dollar amounts
subject to federal income taxation, if any, will vary for each shareholder
depending upon the size and duration of each shareholder's investment in the
Fund. In the event that the Fund derives taxable net investment income, it
intends to designate as taxable dividends the same percentage of each day's
dividend as its actual taxable net investment income bears to its total net
investment income earned on that day. Therefore, the percentage of each day's
dividend designated as taxable, if any, may vary from day to day.

                  If a shareholder fails to furnish a correct taxpayer
identification number, fails to report fully dividend or interest income, or
fails to certify that he has provided a correct taxpayer identification number
and that he is not subject to withholding, then the shareholder may be subject
to a 31% "backup withholding" tax with respect to (a) taxable dividends and
distributions and (b) the proceeds of any redemptions of Fund shares. An
individual's 


                                       21

<PAGE>   53
taxpayer identification number is his social security number. Corporate
shareholders and other shareholders specified in the Code are or may be exempt
from backup withholding. The backup withholding tax is not an additional tax and
may be credited against a taxpayer's federal income tax liability.

      THE FOREGOING IS ONLY A SUMMARY OF CERTAIN MATERIAL TAX CONSEQUENCES
       AFFECTING A FUND AND ITS SHAREHOLDERS. SHAREHOLDERS ARE ADVISED TO
               CONSULT THEIR OWN TAX ADVISERS WITH RESPECT TO THE
              PARTICULAR TAX CONSEQUENCES TO THEM OF AN INVESTMENT
                                  IN THE FUND.

                             DETERMINATION OF YIELD

                  From time to time, each Fund may quote its yield, effective
yield and tax equivalent yield, as applicable, in advertisements or in reports
and other communications to shareholders. A Fund's seven-day yield is calculated
by (i) determining the net change in the value of a hypothetical pre-existing
account in the Fund having a balance of one share at the beginning of a seven
calendar day period for which yield is to be quoted, (ii) dividing the net
change by the value of the account at the beginning of the period to obtain the
base period return and (iii) annualizing the results (i.e., multiplying the base
period return by 365/7). The net change in the value of the account reflects the
value of additional shares purchased with dividends declared on the original
share and any such additional shares, but does not include realized gains and
losses or unrealized appreciation and depreciation. The Fund's seven-day
compound effective annualized yield is calculated by adding 1 to the base period
return (calculated as described above), raising the sum to a power equal to
365/7 and subtracting 1. The Tax Exempt Fund's tax equivalent yield is
calculated by dividing that portion of the base period return which is exempt
from federal personal income taxes by 1 minus the highest marginal federal
individual income tax rate and adding the quotient to that portion, if any, of
the yield which is not exempt from those taxes.

                  Each Fund's yield will vary from time to time depending upon
market conditions, the composition of its portfolio and operating expenses
allocable to it. Yield information may be useful in reviewing a Fund's
performance and for providing a basis for comparison with other investment
alternatives. However, the Fund's yield will fluctuate, unlike certain bank
deposits or other investments which pay a fixed yield for a stated period of
time. In comparing the Fund's yield with that of other money market funds,
investors should give consideration to the quality and maturity of the portfolio
securities of the respective funds.

                                    APPENDIX

                   DESCRIPTION OF COMMERCIAL PAPER RATINGS

            Commercial paper rated A-1 by Standard & Poor's Ratings 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 Investor Services, 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.

            Short term obligations, including commercial paper, rated A1 + by
IBCA are obligations supported by the highest capacity for timely repayment.
Obligations rated A1 have a very strong capacity for timely repayment.
Obligations rated A2 have a strong capacity for timely repayment, although such
capacity may be susceptible to adverse changes in business, economic or
financial conditions.

            Fitch Investors Services, Inc. employs the rating F-1+ to indicate
issues regarded as having the strongest degree of assurance for timely payment.
The rating F-1 reflects an assurance of timely payment only slightly less in
degree than issues rated F-1+, while the rating F-2 indicates a satisfactory
degree of assurance for timely payment, although the margin of safety is not as
great as indicated by the F-1+ and F-1 categories.

            Duff & Phelps, Inc. employs the designation of Duff 1 with
respect to top grade commercial paper and bank money instruments.  Duff 1+
indicates the highest certainty of timely payment: short-term liquidity is
clearly outstanding and safety is just below risk-free U.S. Treasury
short-term obligations.  Duff 1- indicates high certainty of timely payment.
Duff 2 indicates good certainty of timely payment: liquidity factors and
company fundamentals are sound.

                 DESCRIPTION OF MUNICIPAL SECURITIES RATINGS

            The following summarizes the highest two ratings used by S&P for
Municipal Securities:

            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.
<PAGE>   56
            AA - Debt rated AA has a very strong capacity to pay interest and
repay principal and differs from AAA issues only in small degree.

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

            The following summarizes the highest two ratings used by Moody's for
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 edge." 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 As are judged to be of high quality by all
standards. Together with the Aaa group they are rated lower than the best bonds
because margins of protection may not be as large as in Aaa securities or
fluctuation of protective elements may be of greater amplitude or there may be
other elements present which make the long-term risks appear somewhat larger
than in Aaa securities.

            Moody's applies numerical modifiers (1,2 and 3) with respect to the
bonds rated Aa. 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.

            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 (+) 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.


                                      A-2

1.  ORGANIZATION:

    Warburg, Pincus Money Market Fund, Inc. and Warburg, Pincus Tax Free Money
Market Fund, Inc. (collectively referred to as the "Funds") were incorporated
on July 24, 1998 under the laws of the State of Maryland. The Funds are
registered under the Investment Company Act of 1940, as amended, as
diversified, open-end management investment companies. The Funds' charter
authorizes its Board of Directors 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 and two billion are designated Advisor Shares.
Common Shares bear fees at .25% of average daily net asset value pursuant to a
12b-1 distribution plan. The Funds have not commenced operations except those
related to organizational matters and the sale of 100,000 Common Shares of each
Fund (the "Initial Shares") to Warburg Pincus Asset Management, Inc., the
Funds' investment adviser (the "Adviser") on September 17, 1998.

2.  ORGANIZATION COSTS, OFFERING COSTS AND TRANSACTIONS WITH AFFILIATES:

    Certain organizational costs incurred by the Funds have been paid for by the
Funds' Adviser. These costs amounted to $10,650 per Fund. Offering costs,
including initial registration costs, have been deferred and will be charged
to expense during the Funds' first year of operation.

    Certain officers and directors of the Funds are also officers and a
director of the Adviser. These officers and directors are paid no fees by the
Funds for serving as an officer or director.

     Registrant, officers and directors of Warburg, of Counsellors Securities
Inc. ("Counsellors Securities") and of Registrant are covered by insurance
policies indemnifying them for liability incurred in connection with the
operation of Registrant. These policies provide insurance for any "Wrongful Act"
of an officer, director or trustee. Wrongful Act is defined as breach of duty,
neglect, error, misstatement, misleading statement, omission or other act done
or wrongfully attempted by an officer, director or trustee in connection with
the operation of Registrant. Discussion of this coverage is incorporated by
reference to Item 27 of Part C of the Fund's initial Registration Statement on
Form N-1A filed on July 24, 1998.

Warburg Pincus Asset Management, Inc.
466 Lexington Avenue
New York, New York 10017-3147

Dear Sirs:

            Warburg, Pincus WorldPerks Money Market Fund, Inc. (the "Fund"), a
corporation organized and existing under the laws of the State of Maryland,
herewith confirms its agreement with Warburg Pincus Asset Management, Inc. (the
"Adviser") as follows:

      1.    Investment Description; Appointment

            The Fund desires to employ the capital of the Fund by investing and
reinvesting in investments of the kind and in accordance with the limitations
specified in its Articles of Incorporation, as may be amended from time to time,
and in the Fund's Prospectus(es) and Statement(s) of Additional Information, as
from time to time in effect (the "Prospectus" and "SAI," respectively), and in
such manner and to such extent as may from time to time be approved by the Board
of Directors of the Fund. Copies of the Fund's Prospectus and SAI have been or
will be submitted to the Adviser. The Fund desires to employ and hereby appoints
the Adviser to act as investment adviser to the Fund. The Adviser accepts the
appointment and agrees to furnish the services for the compensation set forth
below.

      2.    Services as Investment Adviser

            Subject to the supervision and direction of the Board of Directors
of the Fund, the Adviser will (a) act in strict conformity with the Fund's
Articles of Incorporation, the Investment Company Act of 1940 (the "1940 Act")
and the Investment Advisers Act of 1940, as the same may from time to time be
amended, (b) manage the Fund's assets in accordance with the Fund's investment
objective and policies as stated in the Fund's Prospectus and SAI, (c) make
investment decisions for the Fund, (d) place purchase and sale orders for
securities on behalf of the Fund, (e) exercise voting rights in respect of
portfolio securities and other investments for the Fund, and (f) monitor and
evaluate the services provided by the Fund's investment sub-adviser(s), if any,
under the terms of the applicable investment sub-advisory agreement(s). In
providing those services, the Adviser will provide investment research and
supervision of the Fund's investments and conduct a continual program of
investment, evaluation and, if appropriate, sale and reinvestment of the Fund's
assets. In addition, the Adviser will furnish the Fund



<PAGE>   2

with whatever statistical information the Fund may reasonably request with
respect to the securities that the Fund may hold or contemplate purchasing.

            Subject to the approval of the Board of Directors of the Fund and,
where required by law, the Fund's shareholders, the Adviser may engage an
investment sub-adviser or sub-advisers to provide advisory services in respect
of the Fund and may delegate to such investment sub-adviser(s) the
responsibilities described in subparagraphs (b), (c), (d) and (e) above. In the
event that an investment sub-adviser's engagement has been terminated, the
Adviser shall be responsible for furnishing the Fund with the services required
to be performed by such investment sub-adviser(s) under the applicable
investment sub-advisory agreements or arranging for a successor investment
sub-adviser(s) to provide such services on terms and conditions acceptable to
the Fund and the Fund's Board of Directors and subject to the requirements of
the 1940 Act.

      3.    Brokerage

            In executing transactions for the Fund, selecting brokers or dealers
and negotiating any brokerage commission rates, the Adviser will use its best
efforts to seek the best overall terms available. In assessing the best overall
terms available for any portfolio transaction, the Adviser will consider all
factors it deems relevant including, but not limited to, breadth of the market
in the security, the price of the security, the financial condition and
execution capability of the broker or dealer and the reasonableness of any
commission for the specific transaction and for transactions executed through
the broker or dealer in the aggregate. In selecting brokers or dealers to
execute a particular transaction and in evaluating the best overall terms
available, the Adviser may consider the brokerage and research services (as
those terms are defined in Section 28(e) of the Securities Exchange Act of 1934,
as the same may from time to time be amended) provided to the Fund and/or other
accounts over which the Adviser or an affiliate exercises investment discretion.

      4.    Information Provided to the Fund

            The Adviser will keep the Fund informed of developments materially
affecting the Fund, and will, on its own initiative, furnish the Fund from time
to time with whatever information the Adviser believes is appropriate for this
purpose.

      5.    Standard of Care

            The Adviser shall exercise its best judgment in rendering the
services listed in paragraphs 2, 3 and 4 above. The Adviser shall not be liable
for any error of judgment or mistake of law or for any loss suffered by the Fund
in connection with the matters to which this Agreement relates, provided that

                                      -2-

<PAGE>   3

nothing herein shall be deemed to protect or purport to protect the Adviser
against any liability to the Fund or to shareholders of the Fund to which the
Adviser would otherwise be subject by reason of willful misfeasance, bad faith
or gross negligence on its part in the performance of its duties or by reason of
the Adviser's reckless disregard of its obligations and duties under this
Agreement.

      6.    Compensation

            In consideration of the services rendered pursuant to this
Agreement, the Fund will pay the Adviser an annual fee calculated at an annual
rate of .50% of the Fund's average daily net assets. The fee for the period from
the date the Fund's initial registration statement is declared effective by the
Securities and Exchange Commission to the end of the year during which the
initial registration statement is declared effective shall be prorated according
to the proportion that such period bears to the full yearly period. Upon any
termination of this Agreement before the end of a year, the fee for such part of
that year shall be prorated according to the proportion that such period bears
to the full yearly period and shall be payable upon the date of termination of
this Agreement. For the purpose of determining fees payable to the Adviser, the
value of the Fund's net assets shall be computed at the times and in the manner
specified in the Fund's Prospectus or SAI.

      7.    Expenses

            The Adviser will bear all expenses in connection with the
performance of its services under this Agreement, including the fees payable to
any investment sub-adviser engaged pursuant to paragraph 2 of this Agreement.
The Fund will bear its proportionate share of certain other expenses to be
incurred in its operation, including: investment advisory and administration
fees; taxes, interest, brokerage fees and commissions, if any; fees of Directors
of the Fund who are not officers, directors, or employees of the Adviser or any
of its affiliates; fees of any pricing service employed to value shares of the
Fund; Securities and Exchange Commission fees and state blue sky qualification
fees; charges of custodians and transfer and dividend disbursing agents; the
Fund's proportionate share of insurance premiums; outside auditing and legal
expenses; costs of maintenance of the Fund's existence; costs attributable to
investor services, including, without limitation, telephone and personnel
expenses; costs of preparing and printing prospectuses and statements of
additional information for regulatory purposes and for distribution to existing
shareholders; costs of shareholders' reports and meetings of the shareholders of
the Fund and of the officers or Board of Directors of the Fund; and any
extraordinary expenses.

            The Fund will be responsible for nonrecurring expenses which may
arise, including costs of litigation to which the Fund

                                      -3-

<PAGE>   4

is a party and of indemnifying officers and Directors of the Fund with respect
to such litigation and other expenses as determined by the Directors.

      8.    Services to Other Companies or Accounts

            The Fund understands that the Adviser now acts, will continue to act
and may act in the future as investment adviser to fiduciary and other managed
accounts and to one or more other investment companies or series of investment
companies, and the Fund has no objection to the Adviser so acting, provided that
whenever the Fund and one or more other accounts or investment companies or
portfolios advised by the Adviser have available funds for investment,
investments suitable and appropriate for each will be allocated in accordance
with a formula believed to be equitable to each entity. The Fund recognizes that
in some cases this procedure may adversely affect the size of the position
obtainable for the Fund. In addition, the Fund understands that the persons
employed by the Adviser to assist in the performance of the Adviser's duties
hereunder will not devote their full time to such service and nothing contained
herein shall be deemed to limit or restrict the right of the Adviser or any
affiliate of the Adviser to engage in and devote time and attention to other
businesses or to render services of whatever kind or nature, provided that doing
so does not adversely affect the ability of the adviser to perform its services
under this Agreement.

      9.    Term of Agreement

            This Agreement shall continue until April 17, 2000 and thereafter
shall continue automatically for successive annual periods, provided such
continuance is specifically approved at least annually by (a) the Board of
Directors of the Fund or (b) a vote of a "majority" (as defined in the 1940 Act)
of the Fund's outstanding voting securities, provided that in either event the
continuance is also approved by a majority of the Board of Directors who are not
"interested persons" (as defined in said Act) of any party to this Agreement, by
vote cast in person at a meeting called for the purpose of voting on such
approval. This Agreement is terminable, without penalty, on 60 days' written
notice, by the Board of Directors of the Fund or by vote of holders of a
majority of the Fund's shares, or upon 90 days' written notice, by the Adviser.
This Agreement will also terminate automatically in the event of its assignment
(as defined in said Act).

      10.   Representation by the Fund

            The Fund represents that a copy of its Articles of Incorporation,
dated July 24, 1998, together with all amendments thereto, is on file in the
Department of Assessments and Taxation of the State of Maryland.

                                      -4-

      11.   Miscellaneous

            The Fund recognizes that directors, officers and employees of the
Adviser may from time to time serve as directors, trustees, officers and
employees of corporations and business trusts (including other investment
companies) and that such other corporations and trusts may include the name
"Warburg, Pincus" as part of their names, and that the Adviser or its affiliates
may enter into advisory or other agreements with such other corporations and
trusts. If the Adviser ceases to act as the investment adviser of the Fund's
shares, the Fund agrees that, at the Adviser's request, the Fund's license to
use the words "Warburg, Pincus" will terminate and that the Fund will take all
necessary action to change the name of the Fund to names not including the words
"Warburg, Pincus".

herein set forth for the compensation herein provided.

      2.    Delivery of Documents. The Investment Advisor shall provide to the
Sub-Advisor copies of the Fund's most recent prospectus and statement of
additional information (including any supplement thereto) which relate to any
class of shares representing interests in the Fund (each such prospectus and
statement of additional information as presently in effect, and as they shall
from time to time be amended and supplemented, is herein respectively called a
"Prospectus" and a "Statement of Additional Information").

      3.    Sub-Advisory Services to the Fund. Subject to the supervision of the
Investment Advisor, the Sub-Advisor will supervise the day-to-day operations of
the Fund and perform the following services: (i) provide investment research and
credit analysis concerning the Fund's investments, (ii) conduct a continual
program of investment of the Fund's assets, (iii) place



                                       1
<PAGE>   2
orders for all purchases and sales of the investments made for the Fund and (iv)
maintain the books and records required in connection with its duties hereunder.
In addition, the Sub-Advisor will keep the Investment Advisor informed of
developments materially affecting the Fund. The Sub-Advisor will communicate to
the Investment Advisor on each day that a purchase or sale of a security is
effected for the Fund (i) the name of the issuer, (ii) the amount of the
purchase or sale, (iii) the name of the broker or dealer, if any, through which
the purchase or sale will be effected, (iv) the CUSIP number of the security, if
any, and (v) such other information as the Investment Advisor may reasonably
require for purposes of fulfilling its obligations to the Fund under the
Advisory Agreement. The Sub-Advisor will render to the Fund's Board of Directors
such periodic and special reports as the Investment Advisor may reasonably
request. The Sub-Advisor will provide the services rendered by it hereunder in
accordance with the Fund's investment objectives, policies and restrictions as
stated in the Prospectus and Statement of Additional Information.

      4.    Brokerage. The Sub-Advisor may place orders pursuant to its
investment determinations for the Fund either directly with the issuer or with
any broker or dealer. In placing orders, the Sub-Advisor will consider the
experience and skill of the firm's securities traders as well as the firm's
financial responsibility and administrative efficiency. The Sub-Advisor will
attempt to obtain the best price and the most favorable execution of its orders.
Consistent with these obligations, the Sub-Advisor may, subject to the approval
of the Board of Directors, select brokers on the basis of the research,
statistical and pricing services they provide to the Fund. A commission paid to
such brokers may be higher than that which another qualified broker would have
charged for effecting the same transaction, provided that the Sub-Advisor
determines in good faith that such transaction is reasonable in terms either of
the transaction or the overall responsibility of the Sub-Advisor to the Fund and
its other clients and that the total commissions paid by the Fund will be
reasonable in relation to the benefits to the Fund over the long-term. In no
instance will portfolio securities be purchased from or sold to the Fund's
principal distributor, the Investment Advisor, or any affiliate thereof, except
to the extent permitted by an exemptive order of the Securities and Exchange
Commission or by applicable law.

      5.    Compliance with Laws; Confidentiality. The Sub-Advisor agrees that
it will comply with all applicable rules and regulations of all federal and
state regulatory agencies having jurisdiction over the Sub-Advisor in
performance of its duties hereunder (herein called the "Rules"). The Sub-Advisor
will treat confidentially and as proprietary information of the Fund all records
and information relative to the Fund, and will not


                                       2
<PAGE>   3
use such records and information for any purpose other than performance of its
responsibilities and duties hereunder, except after prior notification to and
approval in writing by the Fund, which approval shall not be unreasonably
withheld and may not be withheld where the Sub-Advisor may be exposed to civil
or criminal contempt proceedings for failure to comply, when requested to
divulge such information by duly constituted authorities, or when so requested
by the Fund.

      6.    Control by the Fund's Board of Directors. Any recommendations
concerning the Fund's investment program proposed by the Sub-Advisor to the Fund
and the Investment Advisor pursuant to this Agreement, as well as any other
activities undertaken by the Sub-Advisor on behalf of the Fund pursuant thereto,
shall at all times be subject to any applicable directives of the Board of
Directors of the Fund.

      7.    Services Not Exclusive. The Sub-Advisor's services hereunder are not
deemed to be exclusive, and the Sub-Advisor shall be free to render similar
services to others so long as its services under this Agreement are not impaired
thereby.

      8.    Books and Records. In compliance with the requirements of Rule 31a-3
under the 1940 Act, the Sub-Advisor hereby agrees that all records which it
maintains for the Fund are the property of the Fund and further agrees to
surrender promptly to the Fund any such records upon the Fund's request. The
Sub-Advisor further agrees to preserve for the periods prescribed by Rule 31a-2
under the 1940 Act, the records required to be maintained by the Sub-Advisor
hereunder pursuant to Rule 31a-1 under the 1940 Act.

      9.    Expenses. During the term of this Agreement, the Sub-Advisor will
bear all expenses in connection with the performance of its services under this
Agreement. The Sub-Advisor shall not bear certain other expenses related to the
operation of the Fund including, but not limited to: taxes, interest, brokerage
fees and commissions and any extraordinary expense items.

      10.   Compensation. For the services which the Sub-Advisor will render to
the Investment Advisor under this Agreement, the Investment Advisor will pay to
the Sub-Advisor on the first day of each month, a fee for the previous month
calculated daily, at an annual rate of [.06%] of the Fund's average daily net
assets.

      11.   Limitation on Liability. The Sub-Advisor will not be liable for any
error of judgment or mistake of law or for any loss suffered by the Investment
Advisor or by the Fund in connection with the matters to which this Agreement
relates,


                                       3
<PAGE>   4
except that it shall be liable to the Investment Advisor and the Fund for a loss
resulting from a breach of fiduciary duty with respect to the receipt of
compensation for services or a loss resulting from willful misfeasance, bad
faith or gross negligence on its part in the performance of its duties or from
reckless disregard by it of its obligations or duties under this Agreement.

      12.   Duration and Termination. This Agreement shall become effective with
respect to the Fund upon approval of this Agreement by vote of a majority of the
outstanding voting securities of the Fund and, unless sooner terminated as
provided herein, shall continue with respect to the Fund until April 17, 2000.
Thereafter, if not terminated, this Agreement shall continue in effect for
successive annual periods ending on April 17th, provided such continuance is
specifically approved at least annually (a) by the vote of a majority of those
members of the Board of Directors of the Fund who are not interested persons of
the Fund or any party to this Agreement, cast in person at a meeting called for
the purpose of voting on such approval, and (b) by the Board of Directors of the
Fund or by vote of a majority of the outstanding voting securities of the Fund.
Notwithstanding the foregoing, this Agreement may be terminated at any time,
without the payment of any penalty, by the Fund (by vote of the Board of
Directors of the Fund or by vote of a majority of the outstanding voting
securities of the Fund), or by the Investment Advisor or the Sub-Advisor on
sixty (60) days' written notice. This Agreement will immediately terminate in
the event of its assignment. (As used in this Agreement, the terms "majority of
the outstanding voting securities," "interested person" and "assignment" shall
have the same meaning as such terms have in the 1940 Act.)

      13.   Amendment of this Agreement. No provision of this Agreement may be
changed, discharged or terminated orally, but only by an instrument in writing
signed by the party against which enforcement of the change, discharge or
termination is sought, and no amendment of this Agreement affecting the Fund
shall be effective until approved by vote of the holders of a majority of the
outstanding voting securities of the Fund.

      14.   Miscellaneous. The captions in this Agreement are included for
convenience of reference only and in no way define or delimit any provisions
hereof or otherwise affect their construction or effect. If any provision of
this Agreement shall be held or made invalid by a court decision, statute, rule
or otherwise, the remainder of this Agreement shall not be affected thereby.

parties hereto and their respective successors and shall be governed by Delaware
law.

Counsellors Securities Inc.
466 Lexington Avenue
New York, New York 10017-3147



Ladies and Gentlemen:

            This is to confirm that, in consideration of the agreements
hereinafter contained, the undersigned, Warburg, Pincus WorldPerks Money Market

("Counsellors Securities") shall be, for the period of this Agreement, the
distributor of shares of common stock of the Fund, par value $.001 per share.
The Fund's classes of common stock shall be designated as in the Fund's Articles
of Incorporation.

      1.    Services as Distributor

            1.1   Counsellors Securities will act as agent for the distribution
of the Common Shares and Advisor Shares covered by the Fund's registration
statement on Form N-1A, under the Securities Act of 1933, as amended (the "1933

registration statement, together with the prospectuses (the "prospectus") and
statement of additional information (the "statement of additional information")
included as part of the registration statement, any amendments to the
registration statement, and any supplements to, or material incorporated by
reference into the prospectus or statement of additional information, being
referred to collectively in this Agreement as the "registration statement").

            1.2   Counsellors Securities agrees to use appropriate efforts to
solicit orders for the sale of the Common Shares and Advisor Shares at such
prices and on the terms and conditions set forth in the registration statement
and will undertake such advertising and promotion as it believes is reasonable
in connection with such solicitation.

            1.3   All activities by Counsellors Securities as distributor of the
Common Shares and Advisor Shares shall comply with all applicable laws, rules
and regulations, including, without limitation, all rules and regulations made
or adopted by the Securities and Exchange Commission (the "SEC") or by any


<PAGE>   2

securities association registered under the Securities Exchange Act of 1934, as
amended.

            1.4   Counsellors Securities agrees to (a) provide one or more
persons during normal business hours to respond to telephone questions
concerning the Fund and its performance, (b) provide prospectuses of other funds
advised by Warburg Pincus Asset Management, Inc. to shareholders considering
exercising the exchange privilege and (c) perform such other services as are
described in the registration statement and in the Shareholder Servicing and
Distribution Plan (with respect to Common Shares, the "12b-1 Plan") and in the
Distribution Plan (with respect to Advisor Shares, the "Distribution Plan"),
each adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act ("Rule
12b-1") to be performed by Counsellors Securities, including, without
limitation, distributing and receiving subscription order forms and receiving
written redemption requests.

            1.5   Pursuant to the 12b-1 Plan and the Distribution Plan (each a
"Plan" and together the "Plans"), the Fund will pay Counsellors Securities on
the first business day of each quarter a fee for the previous quarter calculated
at an annual rate of .25% of the average daily net assets of the Common Shares
and Advisor Shares of the Fund as compensation for the services provided by
Counsellors Securities to the Common Shares and Advisor Shares pursuant to this
Agreement. Amounts paid to Counsellors Securities under a Plan may be used by
Counsellors Securities to cover expenses that are primarily intended to result
in, or that are primarily attributable to, (a) the sale of the Common Shares and
Advisor Shares, as set forth in the Plans ("Selling Services"), (b) ongoing
servicing and/or maintenance of the accounts of holders of Common Shares and

Securities related to providing Services; (ii) payments made to, and
reimbursement of expenses of, persons who provide support services in connection
with the distribution of the Common Shares and Advisor Shares including, but not
limited to, office space and equipment, telephone facilities, answering routine

newspaper, magazine and other mass media advertising, and related travel and
entertainment expenses; (v) costs of printing and distributing prospectuses,
statements of additional information and reports of the Fund to prospective
holders of Common Shares and Advisor Shares; (vi) costs involved in obtaining
whatever information, analyses and reports with respect to marketing and
promotional activities for the Common Shares or Advisor Shares that the Fund
may, from time to time, deem advisable; and (vii) costs and expenses relating to
the Fund's participation in the Northwest Worldperks(TM) program.

            1.6   Counsellors Securities acknowledges that, whenever in the
judgment of the Fund's officers such action is warranted for any reason,
including, without limitation, market, economic or political conditions, those
officers may decline to accept any orders for, or make any sales of, the Common
Shares or Advisor Shares until such time as those officers deem it advisable to
accept such orders and to make such sales.

            1.7   Counsellors Securities will act only on its own behalf as
principal should it choose to enter into selling agreements with selected
dealers or others.

            1.8   Counsellors Securities will transmit any orders received by it
for purchase or redemption of the Common Shares and Advisor Shares to State
Street Bank and Trust Company ("State Street"), the Fund's transfer and dividend
disbursing agent, or its successor of which Counsellors Securities is notified
in writing. The Fund will promptly advise Counsellors Securities of the
determination to cease accepting orders or selling Common Shares or Advisor
Shares or to recommence accepting orders or selling Common Shares or Advisor
Shares. The Fund (or its agent) will confirm orders for Common Shares and
Advisor Shares placed through Counsellors Securities upon their receipt, or in
accordance with any exemptive order of the SEC, and will make appropriate book
entries pursuant to the instructions of Counsellors Securities. Counsellors
Securities agrees to cause payment for Common Shares and Advisor Shares and
instructions as to book entries to be delivered promptly to the Fund (or its
agent).

            1.9   The outstanding Common Shares and Advisor Shares are subject
to redemption as set forth in the prospectus. The price to be paid to redeem the
Common Shares and Advisor Shares will be determined as set forth in the
prospectus.

            1.10  Counsellors Securities will prepare and deliver reports to the
Treasurer of the Fund on a regular, at least quarterly, basis, showing the
distribution expenses incurred pursuant to this Agreement, the 12b-1 Plan and
the Distribution Plan adopted by the Fund pursuant to Rule 12b-1 and the
purposes


                                      -3-
<PAGE>   4
therefor, as well as any supplemental reports as the Directors from time to time
may reasonably request.

      2.    Duties of the Fund

            2.1   The Fund agrees at its own expense to execute any and all
documents, to furnish any and all information and to take any other actions that
may be reasonably necessary in connection with the sale of Common Shares and
Advisor Shares in those states that Counsellors Securities may designate.

            2.2   The Fund shall furnish from time to time, for use in
connection with the sale of the Common Shares and Advisor Shares, such
informational reports with respect to the Fund and the Common Shares and Advisor
Shares as Counsellors Securities may reasonably request, all of which shall be
signed by one or more of the Fund's duly authorized officers; and the Fund
warrants that the statements contained in any such reports, when so signed by
one or more of the Fund's officers, shall be true and correct. The Fund shall
also furnish Counsellors Securities upon request with: (a) annual audits of the
Fund's books and accounts made by independent public accountants regularly
retained by the Fund, (b) semiannual unaudited financial statements pertaining
to the Fund, (c) quarterly earnings statements prepared by the Fund, (d) a
monthly itemized list of the securities held by the Fund, (e) monthly balance
sheets as soon as practicable after the end of each month and (f) from time to
time such additional information regarding the Fund's financial condition as
Counsellors Securities may reasonably request.

      3.    Representations and Warranties

            The Fund represents to Counsellors Securities that all registration
statements, prospectuses and statements of additional information filed by the
Fund with the SEC under the 1933 Act and the 1940 Act with respect to the Common
Shares and/or Advisor Shares have been carefully prepared in conformity with the
requirements of the 1933 Act, the 1940 Act and the rules and regulations of the
SEC thereunder. As used in this Agreement the terms "registration statement",
"prospectus" and "statement of additional information" shall mean any
registration statement, prospectus and statement of additional information filed
by the Fund with respect to the Common Shares and/or Advisor Shares with the SEC
and any amendments and supplements thereto which at any time shall have been
filed with the SEC. The Fund represents and warrants to Counsellors Securities
that any registration statement with respect to the Common Shares and/or Advisor
Shares, or prospectus and statement of additional information contained therein,
when such registration statement becomes effective, will include all statements
required to be contained


                                      -4-
<PAGE>   5
therein in conformity with the 1933 Act, the 1940 Act and the rules and
regulations of the SEC; that all statements of fact contained in any
registration statement with respect to the Common Shares and/or Advisor Shares,
prospectus or statement of additional information will be true and correct when
such registration statement becomes effective; and that neither any registration
statement nor any prospectus or statement of additional information with respect
to the Common Shares and/or Advisor Shares when such registration statement
becomes effective will include an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading to a purchaser of the Common Shares and/or
Advisor Shares. Counsellors Securities may, but shall not be obligated to,
propose from time to time such amendment or amendments to any registration
statement and such supplement or supplements to any prospectus or statement of
additional information as, in the light of future developments, may, in the
opinion of Counsellors Securities' counsel, be necessary or advisable. If the
Fund shall not propose such amendment or amendments and/or supplement or
supplements within fifteen (15) days after receipt by the Fund of a written
request from Counsellors Securities to do so, Counsellors Securities may, at its
option, terminate this Agreement. The Fund shall not file any amendment to any
registration statement or supplement to any prospectus or statement of
additional information without giving Counsellors Securities reasonable notice
thereof in advance; provided, however, that nothing contained in this Agreement
shall in any way limit the Fund's right to file at any time such amendments to
any registration statement and/or supplements to any prospectus or statement of
additional information with respect to the Common Shares and/or Advisor Shares,
of whatever character, as the Fund may deem advisable, such right being in all
respects absolute and unconditional.

      4.    Indemnification

            4.1   The Fund agrees to indemnify, defend and hold Counsellors
Securities, its several officers and directors, and any person who controls
Counsellors Securities within the meaning of Section 15 of the 1933 Act, free
and harmless from and against any and all claims, demands, liabilities and
expenses (including the cost of investigating or defending such claims, demands
or liabilities and any counsel fees incurred in connection therewith) which
Counsellors Securities, its officers and directors, or any such controlling
person, may incur under the 1933 Act, the 1940 Act or common law or otherwise,
arising out of or based upon any untrue statement or alleged untrue statement of
a material fact contained in any registration statement, any prospectus or any
statement of additional information with respect to the Common Shares and/or
Advisor Shares, or arising out of or based upon any omission or alleged omission
to state a


                                      -5-
<PAGE>   6
material fact required to be stated in any registration statement, any
prospectus or any statement of additional information with respect to the Common
Shares and/or Advisor Shares, or necessary to make the statements in any of them
not misleading; provided, however, that the Fund's agreement to indemnify
Counsellors Securities, its officers or directors, and any such controlling
person shall not be deemed to cover any claims, demands, liabilities or expenses
arising out of or based upon any statements or representations made by
Counsellors Securities or its representatives or agents other than such
statements and representations as are contained in any registration statement,
prospectus or statement of additional information with respect to the Common
Shares and/or Advisor Shares and in such financial and other statements as are
furnished to Counsellors Securities pursuant to paragraph 2.2 hereof; and
further provided that the Fund's agreement to indemnify Counsellors Securities
and the Fund's representations and warranties hereinbefore set forth in
paragraph 3 shall not be deemed to cover any liability to the Fund or its
shareholders to which Counsellors Securities would otherwise be subject by
reason of willful misfeasance, bad faith or gross negligence in the performance
of its duties, or by reason of Counsellors Securities' reckless disregard of its
obligations and duties under this Agreement. The Fund's agreement to indemnify
Counsellors Securities, its officers and directors, and any such controlling
person, as aforesaid, is expressly conditioned upon the Fund's being notified of
any action brought against Counsellors Securities, its officers or directors, or
any such controlling person, such notification to be given by letter or by
telegram addressed to the Fund at its principal office in New York, New York and
sent to the Fund by the person against whom such action is brought, within ten
(10) days after the summons or other first legal process shall have been served.
The failure to so notify the Fund of any such action shall not relieve the Fund
from any liability that the Fund may have to the person against whom such action
is brought by reason of any such untrue or alleged untrue statement or omission
or alleged omission otherwise than on account of the Fund's indemnity agreement
contained in this paragraph 4.1. The Fund's indemnification agreement contained
in this paragraph 4.1 and the Fund's representations and warranties in this
Agreement shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of Counsellors Securities, its officers and
directors, or any controlling person, and shall survive the delivery of any of
the Fund's shares. This agreement of indemnity will inure exclusively to
Counsellors Securities' benefit, to the benefit of its several officers and
directors, and their respective estates, and to the benefit of the controlling
persons and their successors. The Fund agrees to notify Counsellors Securities
promptly of the commencement of any 


                                      -6-
<PAGE>   7
litigation or proceedings against the Fund or any of its officers or directors
in connection with the issuance and sale of any of the Common Shares and/or
Advisor Shares.

            4.2   Counsellors Securities agrees to indemnify, defend and hold
the Fund, its several officers and directors, and any person who controls the
Fund within the meaning of Section 15 of the 1933 Act, free and harmless from
and against any and all claims, demands, liabilities and expenses (including the
costs of investigating or defending such claims, demands or liabilities and any
counsel fees incurred in connection therewith) that the Fund, its officers or
directors or any such controlling person may incur under the 1933 Act, the 1940
Act or common law or otherwise, but only to the extent that such liability or
expense incurred by the Fund, its officers or directors or such controlling
person resulting from such claims or demands shall arise out of or be based upon
(a) any unauthorized sales literature, advertisements, information, statements
or representations or (b) any untrue or alleged untrue statement of a material
fact contained in information furnished in writing by Counsellors Securities to
the Fund specifically for use in the registration statement and used in the
answers to any of the items of the registration statement or in the
corresponding statements made in the prospectus or statement of additional
information, or shall arise out of or be based upon any omission or alleged
omission to state a material fact in connection with such information furnished
in writing by Counsellors Securities to the Fund and required to be stated in
such answers or necessary to make such information not misleading. Counsellors
Securities' agreement to indemnify the Fund, its officers and directors, and any
such controlling person, as aforesaid, is expressly conditioned upon Counsellors
Securities' being notified of any action brought against the Fund, its officers
or directors, or any such controlling person, such notification to be given by
letter or telegram addressed to Counsellors Securities at its principal office
in New York, New York and sent to Counsellors Securities by the person against
whom such action is brought, within ten (10) days after the summons or other
first legal process shall have been served. The failure to so notify Counsellors
Securities of any such action shall not relieve Counsellors Securities from any
liability that Counsellors Securities may have to the Fund, its officers or
directors, or to such controlling person by reason of any such untrue or alleged
untrue statement or omission or alleged omission otherwise than on account of
Counsellors Securities' indemnity agreement contained in this paragraph 4.2.
Counsellors Securities agrees to notify the Fund promptly of the commencement of
any litigation or proceedings against Counsellors Securities or any of its
officers or directors in connection with the issuance and sale of any of the
Common Shares and/or Advisor Shares.


                                      -7-
<PAGE>   8
            4.3   In case any action shall be brought against any indemnified
party under paragraph 4.1 or 4.2, and it shall timely notify the indemnifying
party of the commencement thereof, the indemnifying party shall be entitled to
participate in, and, to the extent that it shall wish to do so, to assume the
defense thereof with counsel satisfactory to such indemnified party. If the
indemnifying party opts to assume the defense of such action, the indemnifying
party will not be liable to the indemnified party for any legal or other
expenses subsequently incurred by the indemnified party in connection with the
defense thereof other than (a) reasonable costs of investigation or the
furnishing of documents or witnesses and (b) all reasonable fees and expenses of
separate counsel to such indemnified party if (i) the indemnifying party and the
indemnified party shall have agreed to the retention of such counsel or (ii) the
indemnified party shall have concluded reasonably that representation of the
indemnifying party and the indemnified party by the same counsel would be
inappropriate due to actual or potential differing interests between them in the
conduct of the defense of such action.

      5.    Effectiveness of Registration

            None of the Common Shares or Advisor Shares shall be offered by
either Counsellors Securities or the Fund under any of the provisions of this
Agreement and no orders for the purchase or sale of the Common Shares or Advisor
Shares shall be accepted by the Fund if and so long as the effectiveness of the
registration statement shall be suspended under any of the provisions of the
1933 Act or if and so long as the prospectus is not on file with the SEC;

upon PNC Bank (i) to seek such directions, advice or Oral or Written

or Written Instructions unless, under the terms of other provisions of this

otherwise consented to, in writing, by the Fund. The Fund further agrees that,
should PNC Bank be required to provide such information or records to duly
constituted authorities (who may institute civil or criminal contempt
proceedings for failure to comply), PNC Bank shall not be required to seek the
Fund's consent prior to disclosing such information; provided that PNC Bank
gives the Fund prior written notice of the provision of such information and
records.

indemnified against any liability to the Fund or to its shareholders (or any
expenses incident to such liability) arising out of PNC Bank's or its nominees'
own willful misfeasance, bad faith, gross negligence or reckless disregard of
its duties and obligations under this Agreement or PNC Bank's own grossly
negligent failure to perform its duties under this Agreement.

      13.   Responsibility of PNC Bank. PNC Bank shall be under no duty to take
any action on behalf of the Fund except as specifically set forth herein or as

                        resolution of the Fund's Governing Board, authorizing
                        the transaction. In no case may any member of the Fund's
                        Governing Board, or any officer, employee or agent of
                        the Fund withdraw any securities.

                        At PNC Bank's own expense and for its own convenience,
                        PNC Bank may enter into sub-custodian agreements with
                        other United States banks or trust companies to perform
                        duties described in this sub-paragraph c. Such bank or
                        trust company shall have an aggregate capital, surplus
                        and undivided profits, according to its last published
                        report, of at least one million dollars ($1,000,000), if
                        it is a subsidiary or affiliate of PNC Bank, or at least
                        twenty million dollars ($20,000,000) if such bank or

                        a subsidiary or affiliate of PNC Bank. In addition, such
                        bank or trust company must be qualified to act as
                        custodian and agree to comply with the relevant
                        provisions of the 1940 Act and other applicable rules
                        and regulations. Any such arrangement will not be
                        entered into without prior written notice to the Fund.

                        PNC Bank shall remain responsible for the performance of
                        all of its duties as described in this Agreement and
                        shall hold the Fund harmless from its own acts or 
                        omissions, under the standards of care provided for 
                        herein, or the acts and omissions of any sub-custodian
                        chosen by PNC Bank under the terms of this sub-
                        paragraph c.

                        Oral or Written Instructions and not otherwise, PNC

                              consolidation or recapitalization of the Fund;

                              the Fund; provided, however, that securities shall
                              be released only upon payment to PNC Bank of the
                              monies borrowed, except that in cases where
                              additional collateral is required to secure a
                              borrowing already made subject to proper prior
                              authorization, further securities may be released

                              redelivery to it of the securities pledged or
                              hypothecated therefor and upon surrender of the

                              the Fund in connection with such repurchase
                              agreements, but only upon the delivery of the

                              other securities;

                        (x)   release and deliver securities owned by the fund

                        (xi)  release and deliver or exchange securities owned
                              by the Fund for other corporate purposes.

                              describing the nature of the corporate purpose and

                              delivery shall be made when such action is

                  (e)   Use of Book-Entry System. The Fund shall deliver to PNC
Bank certified resolutions of the Fund's Governing Board approving, authorizing
and instructing PNC Bank on a continuous and on-going basis, to deposit in the
Book-Entry System all securities belonging to the Fund eligible for deposit
therein and to utilize the Book-Entry System to the extent possible in
connection with settlements of purchases and sales of securities by the Fund,
and deliveries and returns of securities loaned, subject to repurchase
agreements or used as collateral in connection with borrowings. PNC Bank shall
continue to perform such duties until it receives Written or Oral Instructions
authorizing contrary actions(s). To administer the Book-Entry System properly,
the following provisions shall apply:

                        (i)   With respect to securities of the Fund which are
                              maintained in the Book-Entry system, established
                              pursuant to this sub-paragraph e hereof, the
                              records of PNC Bank shall identify by Book-Entry
                              or otherwise those securities belonging to the
                              Fund. PNC Bank shall furnish the Fund a detailed
                              statement of the Property held for the Fund under
                              this Agreement at least monthly and from time to
                              time and upon written request.

                        (ii)  Securities and any cash of the Fund deposited in
                              the Book-Entry System will at all times be
                              segregated from any assets and cash controlled by
                              PNC Bank in other than a fiduciary or custodian
                              capacity but may be commingled with other assets
                              held in such capacities. PNC Bank and its
                              sub-custodian, if any, will pay out money only
                              upon receipt of securities and will deliver
                              securities only upon the receipt of money.

                        (iii) All books and records maintained by PNC Bank which
                              relate to the Fund's participation in the
                              Book-Entry System will at all times during PNC
                              Bank's regular business hours be open to the
                              inspection of the Fund's duly authorized employees
                              or agents, and the Fund will be furnished with all
                              information in respect of the services rendered to
                              it as it may require.

                        (iv)  PNC Bank will provide the Fund with copies of any
                              report


                                       13
<PAGE>   14
                              obtained by PNC Bank on the system of internal
                              accounting control of the Book-Entry System 
                              promptly after receipt of such a report by PNC 
                              Bank.

      PNC Bank will also provide the Fund with such reports on its own system of
internal control as the Fund may reasonably request from time to time.

            (f)   Registration of Securities. All Securities held for the Fund
which are issued or issuable only in bearer form, except such securities held in
the Book-Entry System, shall be held by PNC Bank in bearer form; all other
securities held for the Fund may be registered in the name of the Fund; PNC
Bank; the Book-Entry System; a sub-custodian; or any duly appointed nominee(s)
of the Fund, PNC Bank, Book-Entry system or sub-custodian. The Fund reserves the
right to instruct PNC Bank as to the method of registration and safekeeping of
the securities of the Fund. The Fund agrees to furnish to PNC Bank appropriate
instruments to enable PNC Bank to hold or deliver in proper form for transfer,
or to register its registered nominee or in the name of the Book-Entry System,
any securities which it may hold for the account of the Fund and which may from
time to time be registered in the name of the Fund. PNC Bank shall hold all such
securities which are not held in the Book-Entry System in a separate account for
the Fund in the name of the Fund physically segregated at all times from those
of any other person or persons.

            (g)   Voting and Other Action. Neither PNC Bank nor its nominee
shall vote any of the securities held pursuant to this Agreement by or for the
account of the Fund, except in accordance with Written Instructions. PNC Bank,
directly or through the use of the Book-Entry System, shall execute in blank and
promptly deliver all notice, proxies, and proxy soliciting


                                       14

is not the Fund then Written or Oral Instructions must designate the person(s)
who owns such securities.

contrary Written Instructions, PNC Bank is authorized to take the following

                              in addition, promptly advise the Fund of such

                              securities belonging to the Fund held by PNC Bank

                  of such shares, which functions shall be the sole
                  responsibility of the Fund.

      (b)   In addition to and neither in lieu nor in contravention of the
            services set forth in the above paragraph (a), the Bank shall: (i)

      (e)   The Bank shall provide additional services on behalf of the Fund
            (e.g., escheatment services) which may be agreed upon in writing

5.    Wire Transfer Operating Guidelines/Articles 4A of the Uniform Commercial
      Code

5.1   The Bank is authorized to promptly debit the appropriate Fund account(s)
      upon the receipt of a payment order in compliance with the selected
      security procedure (the "Security Procedure") chosen for funds transfer
      and in the amount of money that the Bank has been instructed to transfer.
      The Bank shall execute payment orders in compliance with the Security
      Procedure and with the Fund instructions on the execution date provided
      that such payment order is received by the customary deadline for
      processing such a request, unless the payment order specifies a later
      time. All payment orders and communications received after this the
      customary deadline will be deemed to have been received the next business
      day.

5.2   The Fund acknowledges that the Security Procedure it has designated on the
      Fund Selection Form was selected by the Fund from security procedures
      offered by the Bank. The Fund shall restrict access to confidential
      information relating to the Security Procedure to authorized persons as
      communicated to the Bank in writing. The Fund 


                                       4
<PAGE>   7
      must notify the Bank immediately if it has reason to believe unauthorized
      persons may have obtained access to such information or of any change in
      the Fund's authorized personnel. The Bank shall verify the authenticity of
      all Fund instructions according to the Security Procedure.

5.3   The Bank shall process all payment orders on the basis of the account
      number contained in the payment order. In the event of a discrepancy
      between any name indicated on the payment order and the account number,
      the account number shall take precedence and govern.

5.4   The Bank reserves the right to decline to process or delay the processing
      of a payment order which (a) is in excess of the collected balance in the
      account to be charged at the time of the Bank's receipt of such payment
      order; (b) if initiating such payment order would cause the Bank, in the
      Bank's sole judgement, to exceed any volume, aggregate dollar, network,
      time, credit or similar limits which are applicable to the Bank; or (c) if
      the Bank, in good faith, is unable to satisfy itself that the transaction
      has been properly authorized.

5.5   The Bank shall use reasonable efforts to act on all authorized requests to
      cancel or amend payment orders received in compliance with the Security
      Procedure provided that such requests are received in a timely manner
      affording the Bank reasonable opportunity to act. However, the Bank
      assumes no liability if the request for amendment or cancellation cannot
      be satisfied.

5.6   The Bank shall assume no responsibility for failure to detect any
      erroneous payment order provided that the Bank complies with the payment
      order instructions as received and the Bank complies with the Security
      Procedure. The Security Procedure is established for the purpose of
      authenticating payment orders only and not for the detection of errors in
      payment orders.

5.7   The Bank shall assume no responsibility for lost interest with respect to
      the refundable amount of any unauthorized payment order, unless the Bank
      is notified of the unauthorized payment order within thirty (30) days of
      notification by the Bank of the acceptance of such payment order. In no
      event (including failure to execute a payment order) shall the Bank be
      liable for special, indirect or consequential damages, even if advised of
      the possibility of such damages.

5.8   When the Fund initiates or receives Automated Clearing House credit and
      debit entries pursuant to these guidelines and the rules of the National
      Automated Clearing House Association and the New England Clearing House
      Association, the Bank will act as an Originating Depository Financial
      Institution and/or receiving depository Financial Institution, as the case
      may be, with respect to such entries. Credits given by the Bank with
      respect to an ACH credit entry are provisional until the Bank receives
      final settlement for such entry from the Federal Reserve Bank. If the Bank
      does not receive such final settlement, the Fund agrees that the Bank
      shall receive a refund of the amount credited to the Fund in connection
      with such entry, and the party making payment to the Fund via such entry
      shall not be deemed to have paid the amount of the entry.


                                       5
<PAGE>   8
5.9   Confirmation of Bank's execution of payment orders shall ordinarily be
      provided within twenty four (24) hours notice of which may be delivered
      through the Bank's proprietary information systems, or by facsimile or
      call-back. Fund must report any objections to the execution of an order
      within thirty (30) days.

6.    Data Access and Proprietary Information

6.1   The Fund acknowledges that the data bases, computer programs, screen
      formats, report formats, interactive design techniques, and documentation
      manuals furnished to the Fund by the Bank as part of the Fund's ability to
      access certain Fund-related data ("Customer Data") maintained by the Bank
      on data bases under the control and ownership of the Bank or other third
      party ("Data Access Services") constitute copyrighted, trade secret, or
      other proprietary information (collectively, "Proprietary Information") of
      substantial value to the Bank or other third party. In no event shall
      Proprietary Information be deemed Customer Data. The Fund agrees to treat
      all Proprietary Information as proprietary to the Bank and further agrees
      that it shall not divulge any Proprietary Information to any person or
      organization except as may be provided hereunder. Without limiting the
      foregoing, the Fund agrees for itself and its employees and agents:

      (a)   to access Customer Data solely from locations as may be designated
            in writing by the Bank and solely in accordance with the Bank's
            applicable user documentation;

      (b)   to refrain from copying or duplicating in any way the Proprietary
            Information;

      (c)   to refrain from obtaining unauthorized access to any portion of the
            Proprietary Information, and if such access is inadvertently
            obtained, to inform in a timely manner of such fact and dispose of
            such information in accordance with the Bank's instructions;

      (d)   to refrain from causing or allowing the data acquired hereunder from
            being retransmitted to any other computer facility or other
            location, except with the prior written consent of the Bank;

      (e)   that the Fund shall have access only to those authorized
            transactions agreed upon by the parties;

      (f)   to honor all reasonable written requests made by the Bank to protect
            at the Bank's expense the rights of the Bank in Proprietary
            Information at common law, under federal copyright law and under
            other federal or state law.

Each party shall take reasonable efforts to advise its employees of their
obligations pursuant to this Section 6. The obligations of this Section shall
survive any earlier termination of this Agreement.

6.2   If the Fund notifies the Bank that any of the Data Access Services do not
      operate in material compliance with the most recently issued user
      documentation for such services, the Bank shall endeavor in a timely
      manner to correct such failure. Organizations from which the Bank may
      obtain certain data included in the Data Access Services are solely


                                       6
<PAGE>   9
      responsible for the contents of such data and the Fund agrees to make no
      claim against the Bank arising out of the contents of such third-party
      data, including, but not limited to, the accuracy thereof. DATA ACCESS
      SERVICES AND ALL COMPUTER PROGRAMS AND SOFTWARE SPECIFICATIONS USED IN
      CONNECTION THEREWITH ARE PROVIDED ON AN AS IS, AS AVAILABLE BASIS. THE
      BANK EXPRESSLY DISCLAIMS ALL WARRANTIES EXCEPT THOSE EXPRESSLY STATED
      HEREIN INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
      MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

6.3   If the transactions available to the Fund include the ability to originate
      electronic instructions to the Bank in order to (i) effect the transfer or
      movement of cash or Shares or (ii) transmit Shareholder information or
      other information, then in such event the Bank shall be entitled to rely
      on the validity and authenticity of such instruction without undertaking
      any further inquiry as long as such instruction is undertaken in
      conformity with security procedures established by the Bank from time to
      time.

7.    Indemnification

7.1   The Bank shall not be responsible for, and the Fund shall indemnify and
      hold the Bank harmless from and against, any and all losses, damages,
      costs, charges, counsel fees, payments, expenses and liability arising out
      of or attributable to:

      (a)   all actions of the Bank or its agent or subcontractors required to
            be taken pursuant to this Agreement, provided that such actions are
            taken in good faith and without negligence or willful misconduct;

      (b)   the Fund's lack of good faith, negligence or willful misconduct
            which arise out of the breach of any representation or warranty of
            the Fund hereunder;

      (c)   the reliance on or use by the Bank or its agents or subcontractors
            of information, records, documents or services which (i) are
            received by the Bank or its agents or subcontractors, and (ii) have
            been prepared, maintained or performed by the Fund or any other
            person or firm on behalf of the Fund including but not limited to
            any previous transfer agent or registrar;

      (d)   the reliance on, or the carrying out by the Bank or its agents or
            subcontractors of any instructions or requests of the Fund;

      (e)   the offer or sale of Shares in violation of federal or state
            securities laws or regulations requiring that such Shares be
            registered or in violation of any stop order or other determination
            or ruling by any federal or any state agency with respect to the
            offer or sale of such Shares;

      (f)   the negotiations and processing of checks made payable to
            prospective or existing Shareholders tendered to the Bank for the
            purchase of Shares, such checks are commonly known as "third party
            checks"; and


                                       7
<PAGE>   10
      (g)   upon the Fund's request entering into any agreements required by the
            National Securities Clearing Corporation (the "NSCC") required by
            the NSCC for the transmission of Fund or Shareholder data through
            the NSCC clearing systems.

7.2   At any time the Bank may apply to any officer of the Fund for
      instructions, and may consult with legal counsel with respect to any
      matter arising in connection with the services to be performed by the Bank
      under this Agreement, and the Bank and its agents or subcontractors shall
      not be liable and shall be indemnified by the Fund for any action taken or
      omitted by it in reliance upon such instructions or upon the opinion of
      such counsel. The Bank, its agents and subcontractors shall be protected
      and indemnified in acting upon any paper or document, reasonably believed
      to be genuine and to have been signed by the proper person or persons, or
      upon any instruction, information, data, records or documents provided the
      Bank or its agents or subcontractors by machine readable input, telex, CRT
      data entry or other similar means authorized by the Fund, and shall not be
      held to have notice of any change of authority of any person, until
      receipt of written notice thereof from the Fund. The Bank, its agents and
      subcontractors shall also be protected and indemnified in recognizing
      stock certificates which are reasonably believed to bear the proper manual
      or facsimile signatures of the officers of the Fund, and the proper
      countersignature of any former transfer agent or former registrar, or of a
      co-transfer agent or co-registrar.

7.3   In order that the indemnification provisions contained in this Section 6
      shall apply, upon the assertion of a claim for which the Fund may be
      required to indemnify the Bank, the Bank shall promptly notify the Fund of
      such assertion, and shall keep the Fund advised with respect to all
      developments concerning such claim. The Fund shall have the option to
      participate with the Bank in the defense of such claim or to defend
      against said claim in its own name or in the name of the Bank. The Bank
      shall in no case confess any claim or make any compromise in any case in
      which the Fund may be required to indemnify the Bank except with the
      Fund's prior written consent.

8.    Standard of Care

      The Bank shall at all times act in good faith and agrees to use its best
      efforts within reasonable limits to insure the accuracy of all services
      performed under this Agreement, but assumes no responsibility and shall
      not be liable for loss or damage due to errors unless said errors are
      caused by its negligence, bad faith, or willful misconduct or that of its
      employees.

9.    Year 2000

      The Bank will take reasonable steps to ensure that its products (and those
      of its third-party suppliers) reflect the available technology to offer
      products that are Year 2000 ready, including, but not limited to, century
      recognition of dates, calculations that correctly compute same century and
      multi century formulas and date values, and interface values that reflect
      the date issues arising between now and the next one-hundred years, and if
      any changes are required, the Bank will make the changes to its products
      at a price to be agreed upon by the parties and in a commercially
      reasonable time frame and will require third-party suppliers to do
      likewise.

      records to such person.

      the Shareholder records of the Company, other than request for records of
      Shareholders pursuant to standard subpoenas from state or federal
      government authorities (i.e., divorce and criminal actions), the Bank will
      endeavor to notify the Company and to secure instructions from an
      authorized officer of the Company as to such inspection. The Bank
      expressly reserves the right, however, to exhibit the Shareholder records
      to any person whenever it is advised by counsel that it may be held liable
      for the failure to exhibit the Shareholder records to such person.

services listed in paragraph 2 above. Credit Suisse shall not be liable for any
error of judgment or mistake of law or for any loss suffered by the Fund in
connection with the matters to which this Agreement relates provided that
nothing in this Agreement shall be deemed to protect or purport to protect
Credit Suisse against liability to the Fund or its shareholders to which Credit
Suisse would otherwise be subject by reason of willful misfeasance, bad faith or
negligence on its part in the performance of its duties or by reason of Credit
Suisse's reckless disregard of its obligations and duties under this Agreement.

            This Agreement shall become effective as of the date the Fund
commences its investment operations and shall continue until April 17, 2000 and

successive annual periods ending on April 17th of each year, provided that such

"interested persons" (as defined in the Investment Company Act of 1940, as
amended) of any party to this Agreement, by vote cast in person at a meeting
called for the purpose of voting on such approval. This Agreement is terminable,
without penalty, on sixty (60) days' written notice, by the Board of Directors
of the Fund or by vote of holders of a majority of the Fund's shares, or upon
sixty (60) days' written notice, by Credit Suisse.

      7.    Service to Other Companies or Accounts

            The Fund understands that Credit Suisse now acts, will continue to
act and may act in the future as administrator, co-administrator or
administrative services agent to one or more other investment companies, and the
Fund has no objection to Credit Suisse's so acting. The Fund understands that
the persons employed by Credit Suisse to assist in the performance of Credit
Suisse's duties hereunder will not devote their full time to such service and

right of Credit Suisse or any affiliate of Credit Suisse to engage in and devote
time and attention to other businesses or to render services of whatever kind or
nature.

provision of this Agreement, PFPC, in connection with its duties under this
Agreement, shall not be liable for (a) the validity or invalidity or authority
or lack thereof of any Oral or Written Instruction, notice or other instrument

flood or catastrophe, acts of God, insurrection, war, riots or failure of the
mails, transportation, communication or power supply.

            Notwithstanding anything in this Agreement to the contrary, PFPC
shall have no liability to the Fund for any consequential, special or indirect
losses or damages which the Fund may incur or suffer by or as a consequence of

termination of this Agreement before the end of any month, the fee for such part
of a month shall be prorated according to the proportion which such period bears

Service, fees shall be calculated monthly and the value of the Fund's net assets
shall be computed at the times and in the manner specified in the Prospectus and
Statement of Additional Information as from time to time in effect.

      4.    Expenses

            Counsellors Service will bear all expenses in connection with the

the services listed in paragraph 2 above. Counsellors Service shall not be
liable for any error of judgment or mistake of law or for any loss suffered by
the Fund in connection with the matters to which this Agreement relates provided
that nothing in this Agreement shall be deemed to protect or purport to protect
Counsellors Service against liability to the Fund or its shareholders to which
Counsellors Service would otherwise be subject by reason of willful misfeasance,
bad faith or negligence on its part in the performance of its duties or by
reason of Counsellors Service's reckless disregard of its obligations and duties
under this Agreement. Credit Suisse will use its best efforts to supervise the
activities of Counsellors Service and to ensure that Counsellors Service

continuance is specifically approved at least annually by Credit Suisse and by
the Board of Directors of the Fund, including a majority of the Board of
Directors who are not "interested persons" (as defined in the Investment Company
Act of 1940, as amended) of any party to this Agreement, by vote cast in person
at a meeting called for the purpose of voting on such approval. This Agreement
is terminable, without penalty, on sixty (60) days' written notice, by the Board
of Directors of the Fund or by vote of holders of a majority of the Fund's
shares, upon sixty (60) days' written notice, by Credit Suisse or upon sixty
(60) days' written notice, by Counsellors Service.

      7.    Service to Other Companies or Accounts

            Credit Suisse understands that Counsellors Service now acts, will
continue to act and may act in the future as administrator, co-administrator or
administrative services agent to one or more other investment companies, and
Credit Suisse has no objection to Counsellors Service's so acting. Credit Suisse
understands that the persons employed by Counsellors Service to assist in the
performance of Counsellors Service's duties hereunder will not devote their full
time to such service and nothing contained in this Agreement shall be deemed to
limit or restrict the right of Counsellors Service or any affiliate of
Counsellors Service to engage in and devote time and attention to other
businesses or to render services of whatever kind or nature.

September 21, 1998


Warburg, Pincus WorldPerks Money Market Fund, Inc.
466 Lexington Avenue
New York, New York  10017-3147

Ladies and Gentlemen:

We have acted as counsel to Warburg, Pincus WorldPerks Money Market Fund, Inc.
(the "Fund"), a corporation organized under the laws of the State of Maryland,
in connection with the preparation of a registration statement on Form N-1A
covering the offer and sale of an indefinite number of shares of Common Stock of
the Fund (the "Common Stock"), one billion of which are designated "Common
Shares," and two billion of which are designated "Advisor Shares," par value
$.001 per share (collectively, the "Shares").

We have examined copies of the Charter and By-Laws of the Fund, the Fund's
prospectuses and statement of additional information (the "Statement of
Additional Information") included in its Registration Statement on Form N-1A,
Securities Act File No. 333-59801 and Investment Company Act File No. 811-08899
(the "Registration Statement"), all resolutions adopted by the Fund's Board of
Directors (the "Board") at its organizational meeting held on July 20, 1998,
consents of the Board and other records, documents and papers that we have
deemed necessary for the purpose of this opinion. We have also examined such
other statutes and authorities as we have deemed necessary to form a basis for
the opinion hereinafter expressed.

In our examination of the above material, we have assumed the genuineness of all
signatures and the conformity to original documents of all copies submitted to
us. As to various questions of fact material to our opinion, we have relied upon
statements and certificates of officers and representatives of the Fund and
others.

Based upon the foregoing, we are of the opinion that:

      1.    The Fund is duly organized and validly existing as a corporation in
            good standing under the laws of the State of Maryland.

      2.    The 100,000 presently issued and outstanding shares of Common Stock,
            all of which are designated Common Shares, of the Fund have been
            validly and legally issued and are fully paid and nonassessable.

      3.    The Shares of the Fund to be offered for sale pursuant to the
            Registration Statement are, to the extent of the number of Shares
            authorized to be issued by the Fund in its Charter, duly authorized
            and, when sold, issued and paid for as contemplated by the
            Registration Statement, will have been validly and legally issued

Information and to the filing of this opinion as an exhibit to any application
made by or on behalf of the Fund or any distributor or dealer in connection with
the registration or qualification of the Fund or the Shares under the securities

      Re:   Warburg, Pincus Money Market Fund, Inc.

Ladies and Gentlemen:

            We have acted as special Maryland counsel for Warburg, Pincus Money
Market Fund, Inc., a Maryland corporation (the "Fund"), in connection with the
organization of the Fund and the issuance of shares of its common stock, par
value $.001 per share including the Common Shares and the Advisor Shares (the
"Common Stock").

            As Maryland counsel for the Fund, we are familiar with its Charter
and Bylaws. We have examined its Registration Statement on Form N-1A, Securities
Act File No. 333-59801 and Investment Company Act File No. 811-08899, including
the prospectus and statement of additional information contained therein,
substantially in the form in which it is to become effective (the "Registration
Statement"). We have further examined and relied upon a certificate of the
Maryland State Department of Assessments and Taxation to the effect that the
Fund is duly incorporated and existing under the laws of the State of Maryland
and is in good standing and duly authorized to transact business in the State of
Maryland.

            We have also examined and relied upon such corporate records of the
Fund and other documents and certificates with respect to factual matters as we
have deemed necessary to render the opinion expressed herein. We have assumed,
without independent verification, the genuineness of all signatures, the
authenticity of all documents submitted to us as originals, and the conformity
with originals of all documents submitted to us as copies.

            Based on such examination, we are of the opinion and so advise you
that:

            1.    The Fund is a corporation duly organized and validly existing
                  in good standing under the laws of the State of Maryland.

            2.    The 100,000 presently issued and outstanding Common Shares
                  have been duly authorized and are validly issued, fully paid
                  and nonassessable.

            3.    The Common Stock of the Fund to be offered for sale pursuant
                  to the Registration Statement is, to the extent of the number
                  of shares authorized to be issued by the Fund in its Charter,
                  duly authorized and, when sold, issued and paid for as
                  contemplated by the Registration Statement, will have been
                  validly and legally issued and will be fully paid and
                  nonassessable.

            This letter expresses our opinion with respect to the Maryland
General Corporation Law governing matters such as due organization and the
authorization and issuance of stock. It does not extend to the securities or
"blue sky" laws of Maryland, to federal securities laws or to other laws.

            You may rely upon our foregoing opinion in rendering your opinion to
the Fund that is to be filed as an exhibit to the Registration Statement. We
consent to the filing of this opinion as an exhibit to the Registration
Statement.

                                         Very truly yours,

                   SHAREHOLDER SERVICING AND DISTRIBUTION PLAN

            This Shareholder Servicing and Distribution Plan ("Plan") is adopted
by Warburg, Pincus WorldPerks Money Market Fund, Inc., a corporation organized
under the laws of State of Maryland (the "Fund"), with respect to the common
stock, par value $.001 per share, of the Fund other than those designated
Advisor Shares (the "Shares") pursuant to Rule 12b-1 (the "Rule") under the
Investment Company Act of 1940, as amended (the "1940 Act"), subject to the
following terms and conditions:

            SECTION 1. AMOUNT OF PAYMENTS.

            The Fund will pay Counsellors Securities Inc. ("Counsellors
Securities"), a corporation organized under the laws of the State of New York,
for shareholder servicing and distribution services provided to the Shares, an
annual fee of up to .25% of the value of the average daily net assets of the
Shares. Fees to be paid with respect to the Fund under this Plan will be
calculated daily and paid monthly by the Fund.

            SECTION 2. SERVICES PAYABLE UNDER THE PLAN.

            (a) The annual fees described above payable with respect to the Fund
are intended to compensate Counsellors Securities, or enable Counsellors
Securities to compensate other persons ("Service Providers"), including any
other distributor of Shares, for providing (i) ongoing servicing and/or
maintenance of the accounts of holders of Shares ("Shareholder Services"); (ii)
services that are primarily intended to result in, or that are primarily
attributable to, the sale of Shares ("Selling Services"); and/or (iii)
subtransfer agency services, subaccounting services or administrative services
with respect to Shares ("Administrative Services"). Shareholder Services may
include, among other things, responding to inquiries of prospective investors
regarding the Fund and services to shareholders not otherwise required to be
provided by the Fund's custodian or any co-administrator. Selling Services may
include, but are not limited to: the printing and distribution to prospective

reflecting an allocation of overhead and other office expenses related to
providing Services; (ii) to make, or cause to be made, payments, or to provide

connection with the distribution of Shares including, but not limited to, office
space and equipment, telephone facilities, answering routine inquiries regarding
the Fund, and providing any other Service; (iii) to make, or cause to be made,
payments to compensate selected dealers or other authorized persons for
providing any Services; and (iv) to make, or cause to be made, payments in
connection with the Fund's participation in the Northwest Worldperks(TM) 
program. Administrative Services may include, but are not limited to,
establishing and maintaining accounts and records on behalf of Fund
shareholders; processing purchase, redemption and exchange transactions in
Shares; and other similar services not otherwise required to be provided by the

expenses for shareholder servicing, administration and distribution expenses
actually incurred by Counsellors Securities or any Service Provider, and the
payments may exceed expenses actually incurred by Counsellors Securities and/or
a Service Provider. Furthermore, any portion of any fee paid to Counsellors
Securities or to any of its affiliates by the Fund or any of their past profits
or other revenue may be used in their sole discretion to provide services to
shareholders of the Fund or to foster distribution of Shares.

            SECTION 3. ADDITIONAL PAYMENTS.

"Investment Adviser") or an affiliate of either may pay certain broker-dealers,
financial institutions and other industry professionals ("Service
Organizations") for providing administration, subaccounting, transfer agency
and/or other services with respect to holders of Common Shares and certain
recordkeeping organizations a fee (the "Service Fee"). A portion of the Service
Fee may be borne or reimbursed by the Fund. The Service Fee payable to any one
Service Organization is determined based upon a number of factors, including the
nature and quality of service provided, the operations processing requirements
of the relationship and the standardized fee schedule of the Service
Organization or recordkeeper. Payments by the Fund under this Plan shall not be
made to a Service Organization with respect to services for which the Service
Organization is otherwise

either.

            Payments may be made to Service Organizations by Counsellors
Securities, the Investment Adviser or an affiliate of either from any such
entity's own resources, which may include a fee it received from the Fund.

approved by a majority of (a) the outstanding voting Shares, (b) the full Board

operation of this Plan or in any agreements related to it (the "Independent

this Plan and the related agreements.

            SECTION 5. CONTINUANCE OF PLAN.

            This Plan will continue in effect with respect to the Shares from
year to year so long as its continuance is specifically approved annually by
vote of the Fund's Board of Directors in the manner described in Section 4(b)
and 4(c) above. The Fund's Board of Directors will evaluate the appropriateness
of this Plan and its payment terms on a continuing basis and in doing so will
consider all relevant factors, including the types and extent of Shareholder
Services, Selling Services and Administrative Services provided by Counsellors
Securities and/or Service Providers and amounts Counsellors Securities and/or
Service Providers receive under this Plan.

            SECTION 6. TERMINATION.

Fund will be committed to the discretion of the Directors then in office who are
not interested persons of the Fund.

            SECTION 9. WRITTEN REPORTS.

            In each year during which this Plan remains in effect with respect
to the Fund, any person authorized to direct the disposition of monies paid or
payable by the Fund pursuant to the Plan or any related agreement will prepare
and furnish to the Fund's Board of Directors, and the Board will review, at
least quarterly, written reports, complying with the requirements of the Rule,
which set out the amounts expended under this Plan and the purposes for which
those expenditures were made.

            SECTION 10. PRESERVATION OF MATERIALS.

            The Fund will preserve copies of this Plan, any agreement relating
to this Plan and any report made pursuant to Section 8 above, for a period of
not less than six years (the first two years in an easily accessible place) from
the date of this Plan, the agreement or the report.

            SECTION 11. MEANING OF CERTAIN TERMS.

            As used in this Plan, the terms "interested person" and "majority of
the outstanding voting securities" will be deemed to have the same meanings that
those terms have under the 1940 Act and the rules and regulations under the 1940
Act, subject to any exemption that may be granted to the Fund under the 1940 Act
by the Securities and Exchange Commission.

            SECTION 12. DATE OF EFFECTIVENESS.

                                DISTRIBUTION PLAN

            This Distribution Plan (the "Plan") is adopted in accordance with
Rule 12b-1 under the Investment Company Act of 1940, as amended (the "1940

organized under the laws of the State of Maryland (the "Fund"), subject to the
following terms and conditions:

            Section 1. Distribution Agreements; Annual Fee.

            Any officer of the Fund or Counsellors Securities Inc., the Fund's

written agreements in any form duly approved by the Board of Directors of the
Fund (the "Agreements") with institutional shareholders of record,
broker-dealers, financial institutions, depository institutions, retirement
plans and other financial intermediaries ("Service Organizations") relating to
shares of the Fund's common stock, par value $.001 per share, designated Advisor
Shares (the "Advisor Shares"). Pursuant to an Agreement, Service Organizations
will be paid an annual fee out of the assets of the Fund by the Fund directly or
by Counsellors Securities on behalf of the Fund for providing (a) services
primarily intended to result in the sale of Advisor Shares ("Distribution
Services"), (b) shareholder servicing to their customers or clients who are the
record and/or the beneficial owners of Advisor Shares ("Customers")
("Shareholder Services") and/or (c) administrative and accounting services to
Customers ("Administrative Services"). A Service Organization will be paid an

net assets of Customers' Shares with respect to Shareholder Services.

            In addition, the Fund will pay Counsellors Securities an annual fee
of up to .25% of the value of the average net assets of the Advisor Shares. Fees
to be paid with respect to the Fund under this Plan will be calculated daily and
paid monthly by the Fund. Such fees are intended to compensate Counsellors
Securities for Distribution Services (as defined herein) and for the costs and
expenses relating to the Fund's participation in the Northwest Worldperks(TM)
program.

            Section 2. Services.

            The annual fee paid to Service Organizations under Section 1 of the
Plan with respect to Distribution Services, if

any, will compensate Service Organizations to cover certain expenses primarily
intended to result in the sale of Advisor Shares, including, but not limited to:
(a) costs of payments made to employees that engage in the distribution of
Advisor Shares; (b) payments made to, and expenses of, persons who provide
support services in connection with the distribution of Advisor Shares,
including, but not limited to, office space and equipment, telephone facilities,
processing shareholder transactions and providing any other shareholder services
not otherwise provided by the Fund's transfer agent; (c) costs relating to the
formulation and implementation of marketing and promotional activities,
including, but not limited to, direct mail promotions and television, radio,

the Fund to prospective holders of Advisor Shares; (e) costs involved in
preparing, printing and distributing sales literature pertaining to the Fund;
and (f) costs involved in obtaining whatever information, analyses and reports
with respect to marketing and promotional activities that the Fund may, from
time to time, deem advisable.

            The annual fee paid to Service Organizations under Section 1 of the
Plan with respect to Shareholder Services, if any, will compensate Service
Organizations for personal service and/or the maintenance of Customer accounts,
including but not limited to (a) responding to Customer inquiries, (b) providing
information on Customer investments and (c) providing other shareholder liaison
services.

            The annual fee paid to Service Organizations under Section 1 of the
Plan with respect to Administrative Services, if any, will compensate Service
Organizations for administrative and accounting services to their Customers,
including, but not limited to: (a) aggregating and processing purchase and
redemption requests from Customers and placing net purchase and redemption
orders with the Fund's distributor or transfer agent; (b) providing Customers
with a service that invests the assets of their accounts in Advisor Shares; (c)
processing dividend payments from the Fund on behalf of Customers; (d) providing
information periodically to Customers showing their positions in Advisor Shares;
(e) arranging for bank wires; (f) providing sub-accounting with respect to
Advisor Shares beneficially owned by Customers or the information to the Fund
necessary for sub-accounting; (g) forwarding shareholder communications from the

            Payments under this Plan are not tied exclusively to the expenses
for shareholder servicing, administration and distribution expenses actually
incurred by Counsellors Securities or any Service Organization, and the payments

Organization.

            Counsellors Securities, the Fund's investment adviser (the

Service Fee paid may be borne or reimbursed by the Fund. The Service Fee payable
to any particular Service Organization is determined based upon a number of
factors, including the nature and quality of services provided, the operations
processing requirements of the relationship and the standardized fee schedule of

to a Service Organization with respect to services for which the Service
Organization is otherwise compensated by Counsellors Securities, the Investment
Adviser or an affiliate of either.

who are not interested persons of the Fund and who have no direct or indirect
financial interest in the operation of the Plan or in any agreements related to

            The Plan may not be amended to increase materially the amount of the

Board of Directors in the manner described in Section 6 above.

            Section 10. Selection of Certain Directors.

            While the Plan is in effect, the selection and nomination of the

            Section 12. Preservation of Materials.

                              WARBURG PINCUS FUNDS

                                 RULE 18f-3 PLAN

            Rule 18f-3 (the "Rule") under the Investment Company Act of 1940, as
amended (the "1940 Act"), requires that the Board of an investment company
desiring to offer multiple classes pursuant to the Rule adopt a plan setting
forth the separate arrangement and expense allocation of each class (a "Class"),
and any related conversion features or exchange privileges. The differences in
distribution arrangements and expenses among these classes of shares, and the
exchange features of each class, are set forth below in this Plan, which is
subject to change, to the extent permitted by law and by the governing documents
of each fund that adopts this Plan (the "Fund" and together the "Funds"), by
action of the governing Board of the Fund.

            The governing Board, including a majority of the non-interested
Board members, of each Fund, or series thereof, which desires to offer multiple
classes has determined that the following Plan is in the best interests of each
class individually and the Fund as a whole:

            1. Class Designation. Shares of a Fund or series of a Fund shall be
divided into Common Shares and Advisor Shares.

            2. Differences in Services. Counsellors Securities Inc. ("CSI") will
provide shareholder servicing and distribution services to holders of Common
Shares and Advisor Shares. Institutional shareholders of record may also provide
distribution services, shareholder services and/or administrative and accounting
services to or on behalf of their clients or customers who beneficially own
Advisor Shares.

            3. Differences in Distribution Arrangements.

            Common Shares. Common Shares are sold to the general public and are
subject to an annual distribution fee in accordance with a Shareholder Servicing
and Distribution Plan adopted pursuant to Rule 12b-1 under the 1940 Act, under
which Funds pay CSI .25% per annum for services under that Plan. Specified
minimum initial and subsequent purchase amounts are applicable to the Common
Shares. Common Shares are available through certain organizations that may or
may not charge their customers administrative charges or other direct fees in
connection with investing in Common Shares. CSI may pay certain financial
institutions, broker-dealers and recordkeeping organizations a fee based on the
value of accounts maintained by such organizations in Common Shares of a Fund.
<PAGE>   2
            Advisor Shares. Advisor Shares are available for purchase by
financial institutions, retirement plans, broker-dealers, depository
institutions and other financial intermediaries (collectively, "Institutions").
Advisor Shares may be charged a shareholder service fee (the "Shareholder
Service Fee") payable at an annual rate of up to .25%, and a distribution and/or
administrative services fee (the "Distribution Service Fee") payable at an
annual rate of up to .75%, of the average daily net assets of such Class under a
Distribution Plan adopted pursuant to Rule 12b-1 under the 1940 Act. Payments
may be made directly out of the assets of the Fund or by CSI on its behalf.
Additional payments may be made by CSI or an affiliate thereof from time to time
to Institutions for providing distribution, administrative, accounting and/or
other services with respect to Advisor Shares. Payments by the Fund shall not be
made to an Institution pursuant to the Plan with respect to services for which
Institutions are otherwise compensated by CSI or an affiliate thereof. There is
no minimum amount of initial or subsequent purchases of Advisor Shares imposed
on Institutions.

            General. CSI, the Fund's investment adviser (the "Investment
Adviser") or an affiliate of either may pay certain Fund transfer agent fees and
expenses related to accounts of customers of organizations that have entered
into agreements with CSI or the Fund. An organization may use a portion of the
fees paid pursuant to the Plan to compensate the Fund's custodian or transfer
agent for costs related to accounts of customers of the organization that hold
Common Shares or Advisor Shares.

            Payments may be made to organizations, the customers or clients of
which invest in a Fund's Common Shares or Advisor Shares, by CSI, the Investment
Adviser or an affiliate of either from such entity's own resources, which may
include a fee it receives from the Fund.

            4. Expense Allocation. The following expenses shall be allocated, to
the extent practicable, on a Class-by-Class basis: (a) fees under the
Shareholder Servicing and Distribution Plan or Distribution Plan, as applicable;
(b) transfer agent fees identified by the Fund's transfer agent as being
attributable to a specific Class; and (c) expenses incurred in connection with
shareholders' meetings as a result of issues relating to a specific Class.

            The distribution, administrative and shareholder servicing fees and
other expenses listed above which are attributable to a particular Class are
charged directly to the net assets of the particular Class and, thus, are borne
on a pro rata basis by the outstanding shares of that Class; provided, however,
that money market funds and other funds making daily distributions of their net
investment income may allocate these items to each share 


                                      -2-
<PAGE>   3
regardless of class or on the basis of relative net assets (settled shares),
applied in each case consistently.

            5. Conversion Features. No Class shall be subject to any automatic
conversion feature.

            6. Exchange Privileges. Shares of a Class shall be exchangeable only
for (a) shares of the same Class of other investment companies advised by
Warburg Pincus Asset Management, Inc. that are part of the same group of
investment companies and (b) shares of certain other investment companies
specified from time to time.

            7. Additional Information. This Plan is qualified by and subject to
the terms of the then current prospectus for the applicable Class; provided,
however, that none of the terms set forth in any such prospectus shall be
inconsistent with the terms of the Classes contained in this Plan. The
prospectus for each Class contains additional information about that Class and
the applicable Fund's multiple class structure.
