              CREDIT SUISSE WARBURG PINCUS NEW YORK TAX-EXEMPT FUND

                                   RULE 18f-3

                  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 arrangements 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 may be divided into Common Shares, Institutional Shares, Advisor Shares and
Class A Shares.

                  2.       Differences in Services. Credit Suisse Asset
Management Securities, Inc. ("CSAMSI") will provide administrative services
with respect to the Common Shares, Institutional Shares and Advisor Shares of
each Fund. CSAMSI or its affiliates will also provide, or enter into agreements
with other parties to provide, shareholder servicing and/or distribution
services to holders of Fund shares. CSAMSI or its affiliates may compensate
financial-services firms such as banks, brokers and financial advisers
("Institutions") that provide distribution services, shareholder services
and/or administrative and accounting services to or on behalf of their clients
or customers who beneficially own Fund Shares.

                  3.       Differences in Distribution Arrangements.

                  Common Shares. Common Shares are sold to the general public
and may be subject to distribution fees in accordance with a Shareholder
Servicing and Distribution Plan adopted pursuant to Rule 12b-1 under the 1940
Act, under which a Fund may pay CSAMSI a maximum of .25% per annum for services
under that Plan. Specified minimum initial and subsequent purchase amounts are
applicable to the Common Shares. Common Shares are also available through
certain Institutions that may or may not charge their customers transaction fees
or other fees in connection with investing in Common Shares. Certain features of
a Fund, such as the minimum initial or subsequent investment amounts, may be
modified for investments through Institutions and in certain other instances.
CSAMSI or its affiliates may pay certain Institutions a fee based on the value
of accounts maintained by such Institutions in Common Shares of a Fund.
Institutions may also be reimbursed for marketing and other costs.

                  Institutional Shares. Institutional Shares are generally
available for purchase only by investors who have entered into an investment
management agreement with the Fund's investment adviser (the "Adviser") or its
affiliates. Institutional Shares are not subject to annual





distribution fees payable by the Funds that offer Institutional Shares.
Specified minimum initial and subsequent purchase amounts are generally
applicable to the Institutional Shares.

                  Advisor Shares. Advisor Shares are available for purchase
through 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 .50% 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 pursuant to a Distribution Plan to an Institution
directly out of the assets of the Fund or by CSAMSI on the Fund's behalf.
Additional payments may be made by CSAMSI, the Adviser or an affiliate of either
from time to time to Institutions for providing distribution, administrative,
accounting and/or other services with respect to Advisor Shares. Institutions
may also be reimbursed for marketing and other costs. 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 CSAMSI or an affiliate thereof.
There is no minimum amount of initial or subsequent purchases of Advisor Shares.

                  Class A Shares. Class A Shares are offered without any sales
charge. Each Fund's Class A Shares are subject to a Rule 12b-1 fee of .25 of 1%
per year of the average daily net assets of the Class A Shares of such Fund
consisting of distribution payments and/or service fees of .25 of 1% per year of
the average daily net assets of the Class A Shares of such Fund. Specified
minimum initial and subsequent purchase amounts are applicable to the Class A
Shares.

                  General. Payments may be made to organizations, the customers
or clients of which invest in a Fund's Common Shares, Institutional Shares,
Advisor Shares, and Class A Shares by CSAMSI, the Adviser or an affiliate of
either from such entity's own resources, which may include a fee it receives
from the Fund. In certain cases, a portion of such payments may be paid or
reimbursed by the relevant 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.
All other expenses of a Fund shall be allocated among outstanding Classes on the
basis of relative net assets.

                  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 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
that hold themselves out to investors as part of the Credit Suisse family of
funds, subject to certain exceptions as set forth in the prospectus, statement
of additional information or shareholder guide with respect to a particular
class, and (b) shares of certain other investment companies or classes thereof
specified from time to time. In addition, Class A Shares also are exchangeable
for Class A, B and C Shares of certain Credit Suisse Funds that are subject to a
sales charge.

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