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


          This Statement of Additional Information contains additional
information with respect to the Money Fund,  Government Money Fund and Treasury
Money Fund of Master Fund (collectively, the "Taxable Funds") and the Short-Term
Tax-Exempt Fund of Master Tax-Exempt Fund (the portfolios are referred to
individually as a "Fund" and collectively as the "Funds"; Master Fund and Master
Tax-Exempt Fund are referred to individually as a "Company" and collectively as
the "Companies").

          The investment objective of the Money Fund and the Government Money
Fund is to seek as high a level of current income as is consistent with
liquidity and stability of principal.  The Money Fund generally invests in money
market instruments; the Government Money Fund generally invests in obligations
issued or guaranteed by the U.S. Government, its agencies or instrumentalities
and in repurchase agreements collateralized by such obligations.  The investment
objective of the Treasury Money Fund is to seek current income consistent with
liquidity and stability of principal.  The Treasury Money Fund invests primarily
in direct short-term obligations issued by the U.S. Treasury and certain
agencies or instrumentalities of the U.S. Government with a view toward
providing dividend income that is generally considered exempt from state and
local income taxes.  The investment objective of the Short-Term Tax-Exempt Fund
("Short-Term Fund") is to seek a moderate level of current interest income
exempt from Federal income taxes consistent with stability of principal.  The
Short-Term Fund invests substantially all of its assets in high-quality
Municipal Securities (as defined in the Prospectus) and, except during temporary
defensive periods, maintains at least 80% of its assets in tax-exempt
obligations.  All Funds invest in instruments that generally have remaining
maturities of not more than 13 months.  The following policies supplement the
Funds' investment policies as set forth in the Prospectus.

Additional Information on Portfolio Instruments
-----------------------------------------------

         Variable and Floating Rate Instruments
         --------------------------------------

          With respect to variable and floating rate instruments described in
the Prospectus, United States Trust Company of New York ("U.S. Trust" or the
"Investment Adviser") will consider the earning power, cash flows and other
liquidity ratios of the issuers of such instruments and will continuously
monitor their financial ability to meet payment on demand. In determining 
dollar-weighted average portfolio maturity and whether a variable or floating
rate instrument has a remaining maturity of 13 months or less, the maturity of
each instrument
<PAGE>
 
will be computed in accordance with guidelines established by the SEC.

          Repurchase Agreements
          ---------------------

          The repurchase price under the repurchase agreements described in the
Prospectus 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). Securities subject to
repurchase agreements are held by the Funds' custodian (or sub-custodian) or in
the Federal Reserve/Treasury Money book-entry system. Repurchase agreements are
considered loans by a Fund under the Investment Company Act of 1940 (the "1940
Act").

          Securities Lending
          -------------------

          When the Money Fund or Government Money Fund lends its portfolio
securities, it continues to receive interest or dividends on the securities lent
and may simultaneously earn interest on the investment of the cash loan
collateral, which will be invested in readily marketable, high-quality, short-
term obligations.  Although voting rights, or rights to consent, attendant to
securities lent pass to the borrower, such loans may be called at any time and
will be called so that the securities may be voted by a Fund if a material event
affecting the investment is to occur.

          When-Issued and Forward Transactions
          ------------------------------------

          When a Fund agrees to purchase securities on a "when-issued" or
"forward commitment" basis, the custodian will set aside cash or liquid
portfolio securities equal to the amount of the commitment in a separate
account.  Normally, the custodian will set aside portfolio securities to satisfy
a purchase commitment and, in such case, the Fund may be required subsequently
to place additional assets in the separate 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 a 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 a Fund will set aside cash or 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 forward
commitments or commitments to purchase "when-issued" securities ever exceed 25%
of the value of its assets.

          A Fund will purchase securities on a "when-issued" or "forward
commitment" basis only with the intention of completing the transaction.  If
deemed advisable as a matter of investment


                                      -2-
<PAGE>
 
strategy, however, a Fund may dispose of or renegotiate a commitment after it is
entered into, and may sell securities it has committed to purchase before those
securities are delivered to the Fund on the settlement date.  In these cases,
the Fund may realize a taxable capital gain or loss.

          When a Fund engages in "when-issued" or "forward commitment"
transactions, it relies on the other party to consummate the trade.  Failure of
such other party to do so may result in the Funds incurring a loss or missing an
opportunity to obtain a price considered to be advantageous.

          The market value of the securities underlying a "when-issued" purchase
or a forward commitment to purchase securities and any subsequent fluctuations
in their market value are taken into account when determining the market value
of a Fund starting on the day the Fund agrees to purchase the securities.  The
Fund does not earn interest on the securities it has committed to purchase until
they are paid for and delivered on the settlement date.

          Stand-By Commitments
          --------------------

          The Short-Term Fund may acquire "stand-by commitments" with respect to
Municipal Securities held by it. Under a "stand-by commitment," a dealer or bank
agrees to purchase from the Short-Term Fund, at the Fund's option, specified
Municipal Securities at a specified price. 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. "Stand-by commitments" are exercisable
by the Short-Term Fund at any time before the maturity of the underlying
Municipal Securities, and may be sold, transferred or assigned by the Fund only
with the underlying instruments.

          The Short-Term 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 securities which are
acquired subject to the commitment (thus reducing the yield to maturity
otherwise available for the same securities).  Where the Short-Term Fund has
paid any consideration directly or indirectly for a "stand-by commitment," its
cost will be reflected as unrealized depreciation for the period during which
the commitment was held by the Fund.


                                      -3-
<PAGE>
 
          The Short-Term Fund intends to enter into "stand-by commitments" only
with banks and broker/dealers which, in the Investment Adviser's opinion,
present minimal credit risks.  In evaluating the creditworthiness of the issuer
of a "stand-by commitment," the Investment Adviser will review periodically the
issuer's assets, liabilities, contingent claims and other relevant financial
information.

          Municipal Securities
          --------------------

          The Short-Term Fund invests primarily in Municipal Securities as
defined in the Prospectus. Municipal Securities include debt obligations issued
by governmental entities to obtain funds for various public purposes, including
the construction of a wide range of public facilities, the refunding of
outstanding obligations, the payment of general operating expenses, and the
extension of loans to public institutions and facilities. Private activity bonds
that are issued by or on behalf of public authorities to finance various
privately operated facilities are included within the term "Municipal
Securities" only if the interest paid thereon is exempt from regular Federal
income tax and not treated as a specific tax preference item under the Federal
alternative minimum tax.

          The two principal classifications of Municipal Securities are "general
obligations" and "revenue" issues, but the Short-Term Fund's portfolio may also
include "moral obligation" issues, which are normally issued by special-purpose
authorities.  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 Moody's Investors Service, Inc. ("Moody's") and Standard
& Poor's Ratings Group ("S&P") described in the Prospectus and Appendix hereto
represent their opinion as to the quality of Municipal Securities.  It should be
emphasized that these 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 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 Investment Adviser will consider such an event in
determining whether the Short-Term Fund should continue to hold the obligation.

                                      -4-
<PAGE>
 
          The payment of principal and interest on most securities purchased by
the Short-Term Fund will depend upon the ability of the issuers to meet their
obligations.  Each state, the District of Columbia, each of their political
subdivisions, agencies, instrumentalities and authorities, and each multistate
agency of which a state is a member, is a separate "issuer" as that term is used
in this Statement of Additional Information and the Prospectus.  The non-
governmental user of facilities financed by private activity bonds is also
considered to be an "issuer."  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.  The power or ability of an issuer to
meet its obligations for the payment of interest on and principal of its
Municipal Securities may be materially adversely affected by litigation or other
conditions.

          Private activity bonds are or have been issued to obtain funds to
provide, among other things, privately operated housing facilities, pollution
control facilities, convention or trade show facilities, mass transit, airport,
port or parking facilities and certain local facilities for water supply, gas,
electricity or sewage or solid waste disposal.  Private activity bonds are also
issued to privately held or publicly owned corporations in the financing of
commercial or industrial facilities.  State and local governments are authorized
in most states to issue private activity bonds for such purposes in order to
encourage corporations to locate within their communities.  The principal and
interest on these obligations may be payable from the general revenues of the
users of such facilities.

          Among other instruments, the Short-Term Fund may purchase short-term
General Obligation Notes, Tax Anticipation Notes, Bond Anticipation Notes,
Revenue Anticipation Notes, Tax-Exempt Commercial Paper, Construction Loan Notes
and other forms of short-term loans.  Such instruments are issued with a short-
term maturity in anticipation of the receipt of tax funds, the proceeds of bond
placements or other revenues.  In addition, the Fund may invest in long-term
tax-exempt instruments, such as municipal bonds and private activity bonds, to
the extent consistent with the maturity restrictions applicable to it.

          From time to time, proposals have been introduced before Congress for
the purpose of restricting or eliminating the Federal income tax exemption for
interest on Municipal Securities.  For example, under the Tax Reform Act of
1986, interest on certain private activity bonds must be included in an

                                      -5-
<PAGE>
 
investor's Federal alternative minimum taxable income, and corporate investors
must treat all tax-exempt interest as an item of tax preference.  Master Tax-
Exempt Fund cannot, of course, predict what legislation may be proposed in the
future regarding the income tax status of interest on Municipal Securities, or
which proposals, if any, might be enacted.  Such proposals, while pending or if
enacted, might materially adversely affect the availability of Municipal
Securities for investment by the Short-Term Fund and the liquidity and value of
its portfolio.  In such an event, Master Tax-Exempt Fund would re-evaluate the
Fund's investment objective and policies and consider possible changes in its
structure or possible dissolution.

          Opinions relating to the validity of Municipal Securities and to the
exemption of interest thereon from Federal income tax are rendered by bond
counsel to the respective issuers at the time of issuance.  Neither Master Tax-
Exempt Fund nor the Investment Adviser will review the proceedings relating to
the issuance of Municipal Securities or the basis for such opinions.

          Miscellaneous
          -------------

          The Funds may not invest in oil, gas, or mineral leases.

Additional Investment Limitations
---------------------------------

          In addition to the investment limitations set forth in the Prospectus,
the Funds are subject to the investment limitations enumerated below, which may
be changed with respect to a particular Fund only by a vote of the holders of a
majority of such Fund's outstanding Shares (as defined under "Miscellaneous" in
the Prospectus).

          No Fund may:

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

          2.  Act as an underwriter of securities within the meaning of the
Securities Act of 1933, except insofar as the Taxable Funds might be deemed to
be underwriters upon disposition of certain portfolio securities acquired within
the limitation on purchases of restricted securities; and except to the extent
that purchase by the Short-Term Fund of Municipal Securities or other securities
directly from the issuer thereof in accordance with the Fund's investment
objective, policies and limitations may be deemed to be underwriting;

          3.  Purchase or sell real estate, except that each Taxable Fund may
purchase securities of issuers which deal in


                                      -6-
<PAGE>
 
real estate and may purchase securities which are secured by interests in real
estate; and except that the Short-Term Fund may invest in Municipal Securities
secured by real estate or interests therein;

          4.  Purchase or sell commodities or commodity contracts, or invest in
oil, gas, or other mineral exploration or development programs;

          5.  Invest in or sell puts, calls, straddles, spreads, or any
combination thereof; and

          6.  Issue any senior securities, except insofar as any borrowing in
accordance with a Fund's investment limitations might be considered to be the
issuance of a senior security.

          In addition, the Money, Government Money and Treasury Money Funds may
not:

          7.  Make loans, except that (i) each Fund may purchase or hold debt
securities in accordance with its investment objective and policies, and the
Money Fund and the Government Money Fund may enter into repurchase agreements
with respect to obligations issued or guaranteed by the U.S. Government, its
agencies or instrumentalities, and (ii) the Money Fund and the Government Money
Fund may lend portfolio securities in an amount not exceeding 30% of their total
assets;

          8.  Invest in bank obligations having remaining maturities in excess
of one year, except that securities subject to repurchase agreements may bear
longer maturities;

          9.  Invest in companies for the purpose of exercising management or
control;

          10.  Invest more than 5% of a Funds's total assets in securities
issued by companies which, together with any predecessor, have been in
continuous operation for fewer than three years;

          11.  Purchase foreign securities; except the Money Fund may purchase
certificates of deposit, bankers' acceptances, or other similar obligations
issued by domestic  branches of foreign banks and foreign branches of U.S. banks
in an amount not to exceed 20% of its total net assets;

          12.   Acquire any other investment company or investment company
security, except in connection with a merger, consolidation, reorganization, or
acquisition of assets or where otherwise permitted by the Investment Company Act
of 1940;

                                      -7-
<PAGE>
 
          13.  Invest in obligations of foreign branches of financial
institutions or in domestic branches of foreign banks, if immediately after such
purchase (i) more than 5% of the value of a Fund's total assets would be
invested in obligations of any one foreign branch of the financial institution
or domestic branch of a foreign bank; or (ii) more than 20% of its total assets
would be invested in foreign branches of financial institutions or in domestic
branches of foreign banks;

          14.  Purchase any securities which would cause more than 25% of the
value of a Fund's total assets at the time of purchase to be invested in the
securities of one or more issuers conducting their principal business activities
in the same industry, provided that (a) there is no limitation with respect to
securities issued or guaranteed by the U.S. Government or domestic bank
obligations, and (b) neither all finance companies, as a group, nor all utility
companies, as a group, are considered a single industry for purposes of this
policy; and

          15.  Knowingly invest more than 10% of the value of a Fund's total
assets in illiquid securities, including repurchase agreements with remaining
maturities in excess of seven days, restricted securities, and other securities
for which market quotations are not readily available.

          In addition, the Short-Term Fund may not:

          16.  Make loans, except that the Fund may purchase or hold debt
obligations in accordance with its investment objective, policies, and
limitations; and

          17.  Invest in industrial revenue bonds where the payment of principal
and interest are the responsibility of a company (including its predecessors)
with less than three years of continuous operation;

          18.  Knowingly invest more than 10% of the value of its total assets
in securities which may be illiquid in light of legal or contractual
restrictions on resale or the absence of readily available market quotations;

          19.  Purchase any securities which would cause more than 25% of the
value of its total assets at the time of purchase to be invested in the
securities of one or more issuers conducting their principal business activities
in the same industry, provided that there is no limitation with respect to
domestic bank obligations or securities issued or guaranteed by the United
States; any state or territory; any possession of the U.S. Government; the
District of Columbia; or any of their authorities, agencies, instrumentalities,
or political subdivisions; and


                                      -8-
<PAGE>
 
          20.  Purchase securities of other investment companies (except as part
of a merger, consolidation or reorganization or purchase of assets approved by
the Fund's shareholders), provided that the Fund may purchase shares of any
registered, open-end investment company, if immediately after any such purchase,
the Fund does not (a) own more than 3% of the outstanding voting stock of any
one investment company, (b) invest more than 5% of the value of its total assets
in the securities of any one investment company, or (c) invest more than 10% of
the value of its total assets in the aggregate in securities of investment
companies.

                                 *     *     *

          If a percentage limitation is satisfied at the time of investment, a
later increase or decrease in such percentage resulting from a change in value
of a Fund's portfolio securities will not constitute a violation of such
limitation.

          For the purpose of Investment Limitation No. 3, the prohibition of
purchases of real estate includes acquisition of limited partnership interests
in partnerships formed with a view toward investing in real estate, but does not
prohibit purchases of shares in real estate investment trusts.

          Notwithstanding Investment Limitations Nos. 15 and 18 above, the
Companies intend to limit the Funds' investments in illiquid securities to 10%
of each Fund's net (rather than total) assets.

          Notwithstanding the proviso in Investment Limitation No. 19, to the
extent that the Short-Term Fund has invested more than 20% of the value of its
assets in taxable securities on a temporary defensive basis, the industry
diversification limitation in Investment Limitation No. 19 shall apply to
taxable securities issued or guaranteed by any state, territory, or possession
of the U.S. Government; the District of Columbia; or any of their authorities,
agencies, instrumentalities, or political subdivisions.

          In order to permit the sale of Shares in certain states, the Companies
may make other commitments more restrictive than the investment policies and
limitations described above and in the Funds' Prospectus.  Should the Companies
determine that any such commitment is no longer in the Funds' best interests,
they will revoke the commitment by terminating sales of the Shares to investors
residing in the state involved.


                                      -9-

                        NET ASSET VALUE AND NET INCOME
                        ------------------------------

          The Companies use the amortized cost method of valuation to value
Shares in the Funds. Pursuant to this method, a security is valued at its cost
initially, and thereafter a constant amortization to maturity of any discount or
premium is assumed, regardless of the impact of fluctuating interest rates on
the market value of the security. This method may result in periods during which
value, as determined by amortized cost, is higher or lower than the price the
Fund involved would receive if it sold the security. The market value of
portfolio securities held by the Funds can be expected to vary inversely with
changes in prevailing interest rates.

          The Funds invest only in high-quality instruments and maintain a
dollar-weighted average portfolio maturity appropriate to their objective of
maintaining a constant net asset value per Share.  The Funds will not purchase
any security deemed to have a remaining maturity of more than 13 months within
the meaning of the 1940 Act or maintain a dollar-weighted average portfolio
maturity which exceeds 90 days.  The Companies' Boards of Directors have
established procedures that are intended to stabilize the net asset value per
Share of each Fund for purposes of sales and redemptions at $1.00.  These
procedures include the determination, at such intervals as the Boards deem
appropriate, of the extent, if any, to which the net asset value per Share of a
Fund calculated by using available market quotations deviates from $1.00 per
Share.  In the event such deviation exceeds one half of one percent, the Boards
of Directors will promptly consider what action, if any, should be initiated.
If the Boards of Directors believe that the extent of any deviation from a
Fund's $1.00 amortized cost price per Share may result in material dilution or
other unfair results to new or existing investors, they will take appropriate
steps 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 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.

          Net income of each of the Funds for dividend purposes consists of (i)
interest accrued and discount earned on a Fund's assets, less (ii) amortization
of market premium on such assets, accrued expenses directly attributable to the
Fund, and the general expenses or the expenses common to more than one portfolio
of a Company (e.g., administrative, legal, accounting, and directors' fees)
prorated to each portfolio of the Company on the basis of their relative net
assets.

          ADDITIONAL PURCHASE AND REDEMPTION INFORMATION
          ----------------------------------------------

          Shares are continuously offered for sale by Edgewood Services, Inc.
(the "Distributor"), a wholly-owned subsidiary of Federated Investors, and the
Distributor has agreed to use appropriate efforts to solicit all purchase
orders.  As described in the Prospectus, Shares may be sold to customers
("Customers") of the Investment Adviser, its affiliates and correspondent banks,
and qualified banks, savings and loan associations, broker/dealers and other
institutions ("Shareholder Organizations") that have entered into servicing
agreements with one of the Companies.  Shares are also offered for sale to
institutional investors ("Institutional Investors") and to members of the
general public ("Direct Investors", and collectively with Institutional
Investors, "Investors").  Different types of Customer accounts at Shareholder
Organizations may be used to purchase Shares, including eligible agency and
trust accounts.  In addition, Shareholder Organizations may automatically
"sweep" a Customer's account not less frequently than weekly and invest amounts
in excess of a minimum balance agreed to by the Shareholder Organization and its
Customer in Shares of the Fund selected by the Customer.  Investors purchasing
Shares may include officers, directors, or employees of the particular
Shareholder Organization.

          As stated in the Prospectus, no sales charge is imposed by the
Companies on purchases of Shares.  In addition, no sales load is charged on the
reinvestment of dividends or distributions or in connection with certain Share
exchanges as described in the Prospectus under "Investor Programs--Exchange
Privilege."

          As described in the Prospectus, Direct Investors may redeem Shares by
writing a check.  Checks to redeem Shares are drawn on the Companies' accounts
at United States Trust Company of New York.  Direct Investors will be subject to
the same rules and regulations that U.S. Trust applies to checking accounts and
will have the same rights and duties with respect to stop-payment orders,
"stale" checks, unauthorized signatures, collection of deposits, alterations and
unauthorized endorsements as bank checking account customers do under the New
York Uniform Commercial Code.  When a check is presented to U.S. Trust for
payment, U.S. Trust, as the shareholder's agent, will cause the Fund from which
the redemption is requested to redeem sufficient Shares in the shareholder's
account to cover the amount of the check.

          The Companies may suspend the right of redemption or postpone the date
of payment for Shares for more than 7 days during any period when (a) trading on
the New York Stock Exchange (the "Exchange") is restricted by applicable rules
and regulations of the Securities and Exchange Commission; (b) the

                                     -11-
<PAGE>
 
Exchange is closed for other than customary weekend and holiday closings; (c)
the Securities and Exchange Commission has by order permitted such suspension;
or (d) an emergency exists as determined by the Securities and Exchange
Commission.

          In the event that Shares are redeemed in cash at their net asset
value, a shareholder may receive in payment for such Shares an amount that is
more or less than his original investment due to changes in the market prices of
that Fund's portfolio securities.

          Under limited circumstances, the Companies may accept securities as
payment for Shares.  Securities acquired in this manner will be limited to
securities issued in transactions involving a bona fide reorganization or
                                              ---------                  
statutory merger, or will be limited to other securities (except for municipal
debt securities issued by state political subdivisions or their agencies or
instrumentalities) that: (a) meet the investment objective and policies of any
Fund acquiring such securities; (b) are acquired for investment and not for
resale; (c) are liquid securities that are not restricted as to transfer either
by law or liquidity of market; and (d) have a value that is readily
ascertainable (and not established only by evaluation procedures) as evidenced
by a listing on the American Stock Exchange, New York Stock Exchange or NASDAQ,
or as evidenced by their status as U.S. Government securities, bank certificates
of deposit, banker's acceptances, corporate and other debt securities that are
actively traded, money market securities and other similar securities with a
readily ascertainable value.


                               INVESTOR PROGRAMS
                               -----------------

Systematic Withdrawal Plan
--------------------------

          An Investor who owns Shares with a value of $10,000 or more may begin
a Systematic Withdrawal Plan.  The withdrawal can be on a monthly, quarterly,
semiannual or annual basis.  There are four options for such systematic
withdrawals.  The Investor may request:

          (1)  A fixed-dollar withdrawal;

          (2)  A fixed-share withdrawal;

          (3)  A fixed-percentage withdrawal (based on the current value of the
               account); or

          (4)  A declining-balance withdrawal.

                                     -12-
<PAGE>
 
Prior to participating in a Systematic Withdrawal Plan, the Investor must
deposit any outstanding certificates for Shares with Mutual Funds Service
Company, the Funds' sub-transfer agent.  Under this Plan, dividends and
distributions are automatically reinvested in additional Shares.  Amounts paid
to Investors under this Plan should not be considered as income.  Withdrawal
payments represent proceeds from the sale of Shares, and there will be a
reduction of the shareholder's equity in the Fund involved if the amount of the
withdrawal payments exceeds the dividends paid on the Shares.  This in turn may
result in a complete depletion of the shareholder's investment.  An Investor may
not participate in a program of systematic investing in a Fund while at the same
time participating in the Systematic Withdrawal Plan with respect to an account
in that Fund.

Exchange Privilege
------------------

          Investors and Customers of Shareholder Organizations may exchange
Shares having a value of at least $500 for Shares of any other portfolio of the
Companies.  Shares may be exchanged by wire, telephone or mail and must be made
to accounts of identical registration.  There is no exchange fee imposed by the
Companies.  In order to prevent abuse of this privilege to the disadvantage of
other shareholders, the Companies reserve the right to limit the number of
exchange requests of Investors and Customers of Shareholder Organizations to no
more than six per year.  The Companies may modify or terminate the exchange
program at any time upon 60 days' written notice to shareholders, and may reject
any exchange request.

          For Federal income tax purposes, exchanges are treated as sales on
which the shareholder will realize a gain or loss, depending upon whether the
value of the Shares to be given up in exchange is more or less than the basis in
such Shares at the time of the exchange.  Generally, a shareholder may include
sales loads incurred upon the purchase of Shares in his or her tax basis for
such Shares for the purpose of determining gain or loss on a redemption,
transfer or exchange of such Shares.  However, if the shareholder effects an
exchange of Shares for shares of another portfolio of the Companies within 90
days of the purchase and is able to reduce the sales load applicable to the new
shares (by virtue of the Companies' exchange privilege), the amount equal to
such reduction may not be included in the tax basis of the shareholder's
exchanged Shares but may be included (subject to the limitation) in the tax
basis of the new shares.

Other Investor Programs
-----------------------

          As discussed in the Prospectus, Shares of the Funds may be purchased
in connection with the Automatic Investment Program.  Shares of the Money,
Government Money and Treasury Money Funds


                                     -13-
<PAGE>
 
may also be purchased in connection with certain Retirement Programs.


                          DESCRIPTION OF CAPITAL STOCK
                          ----------------------------

          Master Fund's Charter authorizes its Board of Directors to issue up to
35 billion full and fractional shares of capital stock; and Master Tax-Exempt
Fund's Charter authorizes its Board of Directors to issue up to 14 billion full
and fractional shares of capital stock.  Both Charters authorize the respective
Boards of Directors to classify or reclassify any unissued shares of the
respective Companies into one or more additional classes or series by setting or
changing in any one or more respects their respective preferences, conversion or
other rights, voting powers, restrictions, limitations as to dividends,
qualifications, and terms and conditions of redemption.  The Prospectus
describes the classes of shares into which the Companies' authorized capital is
currently classified.

          Shares have no preemptive rights and only such conversion or exchange
rights as the Boards of Directors may grant in their discretion.  When issued
for payment as described in the Prospectus, Shares will be fully paid and non-
assessable.  In the event of a liquidation or dissolution of a Fund,
shareholders of that Fund are entitled to receive the assets available for
distribution belonging to that Fund and a proportionate distribution, based upon
the relative asset values of the portfolios of the Company involved, of any
general assets of that Company not belonging to any particular portfolio of that
Company which are available for distribution.  In the event of a liquidation or
dissolution of either Company, shareholders of such Company will be entitled to
the same distribution process.

          Shareholders of the Companies are entitled to one vote for each full
share held, and fractional votes for fractional shares held, and will vote in
the aggregate and not by class, except as otherwise required by the 1940 Act or
other applicable law or when the matter to be voted upon affects only the
interests of the shareholders of a particular class.  Voting rights are not
cumulative and, accordingly, the holders of more than 50% of a Company's
aggregate outstanding shares may elect all of that Company's directors,
regardless of the votes of other shareholders.

          Rule 18f-2 under the 1940 Act provides that any matter required to be
submitted to the holders of the outstanding voting securities of an investment
company such as each Company shall not be deemed to have been effectively acted
upon unless approved by the holders of a majority of the outstanding shares of
each portfolio affected by the matter.  A portfolio is affected by a


                                     -14-
<PAGE>
 
matter unless it is clear that the interests of each portfolio in the matter are
substantially identical or that the matter does not affect any interest of the
portfolio.  Under the Rule, the approval of an investment advisory agreement or
any change in a fundamental investment policy would be effectively acted upon
with respect to a portfolio only if approved by a majority of the outstanding
shares of such portfolio.  However, the Rule also provides that the ratification
of the appointment of independent public accountants, the approval of principal
underwriting contracts, and the election of directors may be effectively acted
upon by shareholders of each Company voting without regard to class.

          The Companies' Charters authorize the Boards of Directors, without
shareholder approval (unless otherwise required by applicable law), to (a) sell
and convey the assets of a Fund to another management investment company for
consideration which may include securities issued by the purchaser and, in
connection therewith, to cause all outstanding Shares of the Fund involved to be
redeemed at a price which is equal to their net asset value and which may be
paid in cash or by distribution of the securities or other consideration
received from the sale and conveyance; (b) sell and convert a Fund's assets into
money and, in connection therewith, to cause all outstanding Shares to be
redeemed at their net asset value; or (c) combine the assets belonging to a Fund
with the assets belonging to another portfolio of the Company involved, if the
Board of Directors reasonably determines that such combination will not have a
material adverse effect on shareholders of any portfolio participating in such
combination, and, in connection therewith, to cause all outstanding shares of
any portfolio to be redeemed at their net asset value or converted into shares
of another class of the Company's capital stock at net asset value.  The
exercise of such authority by the Boards of Directors will be subject to the
provisions of the 1940 Act, and the Boards of Directors will not take any action
described in this paragraph unless the proposed action has been disclosed in
writing to the particular Fund's shareholders at least 30 days prior thereto.

          Notwithstanding any provision of Maryland law requiring a greater vote
of a Company's Common Stock (or of the Shares of a Fund voting separately as a
class) in connection with any corporate action, unless otherwise provided by law
(for example, by Rule 18f-2, discussed above) or by the Company's Charter, each
Company may take or authorize such action upon the favorable vote of the holders
of more than 50% of its outstanding Common Stock voting without regard to class.

Investment Advisory and Administration Agreements
-------------------------------------------------

          United States Trust Company of New York serves as Investment Adviser
to the Funds.  In the Investment Advisory Agreements, U.S. Trust has agreed to
provide the services described in the Prospectus.  The Investment Adviser has
also agreed to pay all expenses incurred by it in connection with its activities
under the respective agreements other than the cost of securities, including
brokerage commissions, if any, purchased for the Funds.  See "Expenses" in the
Prospectus.

          For the fiscal year ended March 31, 1993, Master Fund paid the
Investment Adviser $1,776,065, $2,102,373 and $610,108 with respect to the
Money, Government Money and Treasury Money Funds, respectively.  For the same
period, Master Tax-Exempt Fund paid the Investment Adviser $1,629,056 with
respect to the Short-Term Fund.

Investment Adviser waived fees totalling $14,775, $20,874, $1,704 and $20,732
with respect to the Money, Government Money, Treasury Money and Short-Term
Funds, respectively.

          For the fiscal year ended March 31, 1995, Master Fund paid the

          The Investment Advisory Agreements provide that the Investment Adviser
shall not be liable for any error of judgment or mistake of law or for any loss
suffered by the Funds in connection with the performance of such agreements,
except a loss resulting from a breach of fiduciary duty with respect to the
receipt of compensation for advisory services or a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Investment Adviser
in the performance of its duties or from reckless disregard by it of its duties
and obligations thereunder.  In addition, the Investment Adviser has undertaken
in the Investment Advisory Agreements to maintain its policy and practice of
conducting its Asset Management Group independently of its Banking Group.

          Mutual Funds Service Company ("MFSC") and Federated Administrative
Services, an affiliate of the Distributor, jointly serve as the Funds'
administrators.  Under the Administration Agreements, the administrators have
agreed to maintain office facilities for the Funds, furnish the Funds with
statistical and research data, clerical, accounting and bookkeeping services,
and certain other services required by the Funds, and to compute the net asset
value, net income, "exempt-interest dividends," and realized capital gains or
losses, if any, of the respective Funds.  The administrators prepare semiannual
reports to the Securities and Exchange Commission, prepare Federal and state tax
returns, prepare filings with state securities commissions, arrange for and bear
the cost of processing Share purchase and redemption orders, maintain the Funds'
financial accounts and records, and generally assist in the Funds' operations.

respect to the Government Money and Treasury Money Funds, respectively.

Service Organizations
---------------------

          As stated in the Prospectus, the Companies will enter into agreements
with Service Organizations.  Such shareholder servicing agreements will require
the Service Organizations to provide shareholder administrative services to
their Customers who beneficially own Shares in consideration for a Fund's
payment (on an annualized basis) of up to .40% of the average daily net assets
of the Fund's Shares beneficially owned by Customers of the Service
Organization.  Such services with respect to a Fund may include:  (a) assisting
Customers in designating and changing dividend options, account designations and
addresses; (b) providing necessary personnel and facilities to establish and
maintain certain shareholder accounts and records, as may reasonably be
requested from time to time by the Companies; (c) assisting in processing
purchases, exchange and redemption transactions; (d) arranging for the wiring
of funds; (e) transmitting and receiving funds in connection with Customer

                                     -20-
<PAGE>
 
orders to purchase, exchange or redeem Shares; (f) verifying and guaranteeing
Customer signatures in connection with redemption orders, transfers among and
changes in Customer-designated accounts; (g) providing periodic statements
showing a Customer's account balances and, to the extent practicable,
integrating of such information with information concerning other client
transactions otherwise effected with or through the Service Organization; (h)
furnishing on behalf of the Companies' distributor (either separately or on an
integrated basis with other reports sent to a Customer by the Service
Organization) periodic statements and confirmations of all purchases, exchanges
and redemptions of Shares in a Customer's account required by applicable federal
or state law; (i) transmitting proxy statements, annual reports, updating
prospectuses and other communications from the Companies to Customers; (j)
receiving, tabulating and transmitting to the Companies proxies executed by
Customers with respect to annual and special meetings of shareholders of the
Companies; (k) providing reports (at least monthly, but more frequently if so
requested by the Companies' distributor) containing state-by-state listings of
the principal residences of the beneficial owners of the Shares; and (l)
providing or arranging for the provision of such other related services as the
Companies or a Customer may reasonably request.

          The Companies' agreements with Service Organizations are governed by
Administrative Services Plans (the "Plans") adopted by the Companies.  Pursuant
to the Plans, each Company's Board of Directors will review, at least quarterly,
a written report of the amounts expended under the Company's agreements with
Service Organizations and the purposes for which the expenditures were made.  In
addition, the arrangements with Service Organizations will be approved annually
by a majority of each Company's directors, including a majority of the directors
who are not "interested persons" of the Company as defined in the 1940 Act and
have no direct or indirect financial interest in such arrangements (the
"Disinterested Directors").

          Any material amendment to a Company's arrangements with Service
Organizations must be approved by a majority of the Company's Board of Directors
(including a majority of the Disinterested Directors).  So long as the
Companies' arrangements with Service Organizations are in effect, the selection
and nomination of the members of the Companies' Boards of Directors who are not
"interested persons" (as defined in the 1940 Act) of the Companies  will be
committed to the discretion of such non-interested Directors.

          For the fiscal years ended March 31, 1995 and 1994, payments to
Service Organizations totalled $204,060 and $14,775, $174,408 and $21,258,
$45,717 and $2,062, and $236,867 and $20,732 with respect to the Money,
Government Money, Treasury

                                     -21-
<PAGE>
 
Money and Short-Term Tax-Exempt Funds, respectively.  Of these respective
amounts, $203,572 and $14,775, $171,257 and $20,233, $44,596 and $1,075, and
$236,399 and $20,732 were paid to affiliates of U.S. Trust with respect to the
Money, Government Money, Treasury Money and Short-Term Tax-Exempt Funds.

Expenses
--------

          Except as otherwise noted, the Investment Adviser and the
Administrators bear all expenses in connection with the performance of their
services. The Funds bear the expenses incurred in their operations. Expenses of
the Funds include taxes; interest; fees (including fees paid to the Companies'
Directors and officers who are not affiliated with the Distributor or the
Administrators); Securities and Exchange Commission fees; state securities
qualification fees, costs of preparing and printing prospectuses for regulatory
purposes and for distribution to shareholders; advisory, administration and
administrative servicing fees, charges of the custodian, transfer agent, and
dividend disbursing agent; certain insurance premiums; outside auditing and
legal expenses; costs of shareholder reports and meetings; and any extraordinary
expenses. The Funds also pay any brokerage fees and commissions in connection
with the purchase of portfolio securities.

          If the expenses borne by a Fund in any fiscal year exceed expense
limitations imposed by applicable state securities regulations, the Investment
Adviser and the Administrators will reimburse such Fund for a portion of any
such excess to the extent required by such regulations in proportion to the fees
received by them in such year up to the amount of the fees payable to them,
provided, however, to the extent required by such state regulations, the
Investment Adviser and the Administrators have agreed to effect such
reimbursement regardless of the fees payable to them.  The amounts of the above
reimbursements, if any, will be estimated, reconciled and paid on a monthly
basis.  To the Companies' knowledge, of the applicable expense limitations in
effect on the date of this Statement of Additional Information, none is more
restrictive than the following:  2 1/2% of the first $30 million of average
annual net assets, 2% of the next $70 million of average annual net assets and 1
1/2% of average annual net assets in excess of $100 million.

Custodian and Transfer Agent
----------------------------

          United States Trust Company of New York also serves as custodian of
the Funds' assets. Under the custodian agreement, U.S. Trust has agreed to (i)
maintain a separate account or accounts in the name of the Funds; (ii) make
receipts and disbursements of money on behalf of the Funds; (iii) collect

                                     -22-
<PAGE>
 
and receive all income and other payments and distributions on account of the
Funds' portfolio securities; (iv) respond to correspondence from securities
brokers and others relating to its duties; (v) maintain certain financial
accounts and records; and (vi) make periodic reports to the Companies' Boards of
Directors concerning the Funds' operations.  U.S. Trust is entitled to monthly
fees for furnishing custodial services according to the following fee schedule:
on the face value of debt securities and the market value of equity securities,
a fee at the annual rate of .05%; on issues held, $50.00 for each physical issue
held, $25.00 for each book-entry issue held and 1/4 of 1% of market value for
each foreign issue held; on transactions, $25.00 for each physical transaction,
$15.00 for each book-entry transaction and $50.00 for each foreign security
transaction.  In addition, U.S. Trust is entitled to reimbursement for its out-
of-pocket expenses in connection with the above services.

          U.S. Trust also serves as the Funds' transfer agent and dividend
disbursing agent.  In such capacity, U.S. Trust has agreed to (i) issue and
redeem Shares; (ii) address and mail all communications by the Funds to their
shareholders, including reports to shareholders, dividend and distribution
notices, and proxy materials for its meetings of shareholders; (iii) respond to
correspondence by shareholders and others relating to its duties; (iv) maintain
shareholder accounts; and (v) make periodic reports to the Companies concerning
each Fund's operations.  For its transfer agency, dividend disbursing, and
subaccounting services, U.S. Trust is entitled to receive $15.00 per annum per
account and subaccount.  In addition, U.S. Trust is entitled to be reimbursed
for its out-of-pocket expenses for the cost of forms, postage, processing
purchase and redemption orders, handling of proxies, and other similar expenses
in connection with the above services.

          U.S. Trust may, at its own expense, open and maintain custody accounts
with respect to the Funds with other banks or trust companies, and may delegate
its transfer agency obligations to another transfer agent registered or
qualified under applicable law, provided that U.S. Trust shall remain liable for
the performance of all of its custodial and transfer agency duties under the
Custodian and Transfer Agency Agreement, notwithstanding any delegation.
Pursuant to this provision in the agreement, U.S. Trust has entered into a sub-
transfer agency arrangement with MFSC, an affiliate of U.S. Trust, with respect
to accounts of shareholders who are not Customers of U.S. Trust.  For the
services provided by MFSC, U.S. Trust has agreed to pay MFSC $15.00 per annum
per account or subaccount plus out-of-pocket expenses.  MFSC receives no fee
directly from the Companies for any of its sub-transfer agency services.

                                 PORTFOLIO TRANSACTIONS
                                 ----------------------

          Subject to the general control of the Companies' Boards of Directors,
the Investment Adviser is responsible for, makes decisions with respect to, and
places orders for all purchases and sales of all portfolio securities of each of
the Funds.

          The Funds do not intend to seek profits from short-term trading.
Their annual portfolio turnover will be relatively high, but brokerage
commissions are not normally paid on money market instruments, and portfolio
turnover is not expected to have a material effect on the net income of the
Funds.

          Securities purchased and sold by the Funds are generally traded in the
over-the-counter market on a net basis (i.e., without commission) through
dealers, or otherwise involve transactions directly with the issuer of an
instrument.  The cost of securities purchased from underwriters includes an
underwriting commission or concession, and the prices at which securities are
purchased from and sold to dealers include a dealer's mark-up or mark-down.
With respect to over-the-counter transactions, the Funds, where possible, will
deal directly with the dealers who make a market in the securities involved,
except in those circumstances where better prices and execution are available
elsewhere.

          The Investment Advisory Agreements between the Companies and the
Investment Adviser provide that, in executing portfolio transactions and
selecting brokers or dealers, the Investment Adviser will seek to obtain the
best net price and the most favorable execution.  The Investment Adviser shall
consider factors it deems relevant, including the breadth of the market in the
security, the price of the security, the financial condition and execution
capability of the broker or dealer and whether such broker or dealer is selling
shares of the Companies, and the reasonableness of the commission, if any, for
the specific transaction and on a continuing basis.

          In addition, the Investment Advisory Agreements authorize the
Investment Adviser, to the extent permitted by law and subject to the review of
the Companies' Boards of Directors from time to time with respect to the extent
and continuation of the policy, to cause the Funds to pay a broker which
furnishes brokerage and research services a higher commission than that which
might be charged by another broker for effecting the same transaction, provided
that the Investment Adviser determines in good faith that such commission is
reasonable in relation to the value of the brokerage and research services
provided by such broker, viewed in terms of either that particular transaction
or the overall responsibilities of the Investment Adviser to the

                                     -24-
<PAGE>
 
accounts as to which it exercises investment discretion.  Such brokerage and
research services might consist of reports and statistics on specific companies
or industries, general summaries of groups of stocks and their comparative
earnings, or broad overviews of the stock market and the economy.

          Supplementary research information so received is in addition to and
not in lieu of services required to be performed by the Investment Adviser and
does not reduce the investment advisory fees payable by the Funds.  Such
information may be useful to the Investment Adviser in serving the Funds and
other clients and, conversely, supplemental information obtained by the
placement of business of other clients may be useful to the Investment Adviser
in carrying out its obligations to the Funds.

          Portfolio securities will not be purchased from or sold to the
Investment Adviser, the Distributor, or any affiliated person of either of them
(as such term is defined in the 1940 Act) acting as principal, except to the
extent permitted by the Securities and Exchange Commission.

          Investment decisions for the Funds are made independently from those
for other investment companies, common trust funds and other types of funds
managed by the Investment Adviser.  Such other investment companies and funds
may also invest in the same securities as the Funds.  When a purchase or sale of
the same security is made at substantially the same time on behalf of the Funds
and another investment company or common trust fund, the transaction will be
averaged as to price, and available investments allocated as to amount, in a
manner which the Investment Adviser believes to be equitable to the Funds and
such other investment company or common trust fund.  In some instances, this
investment procedure may adversely affect the price paid or received by the
Funds or the size of the position obtained by the Funds.  To the extent
permitted by law, the Investment Adviser may aggregate the securities to be sold
or purchased for the Funds with those to be sold or purchased for other
investment companies or common trust funds in order to obtain best execution.

          The Companies are required to identify any securities of their regular
brokers or dealers (as defined in Rule 10b-1 under the 1940 Act) or their
parents held by the Companies as of the close of their most recent fiscal year.
As of March 31, 1995, the following Funds held the following securities of
Master Fund's regular brokers or dealers or their parents:  (a) the Money Fund
held the following securities:  repurchase agreement with Nomura Securities,
Inc. in the principal amount of $19,685,063, repurchase agreement with Fuji
Securities, Inc. in the principal amount of $20,000,000, commercial paper of
Merrill Lynch & Co., Inc. in the principal amount of $35,000,000 and

                                     -25-
<PAGE>
 
commercial paper of UBS Finance in the principal amount of $30,000,000; and (b)
the Government Money Fund held the following securities:  repurchase agreement
with Nomura Securities, Inc. in the principal amount of $20,216,462 and
repurchase agreement with Fuji Securities, Inc. in the principal amount of
$20,000,000.  Nomura Securities International, Inc., Fuji Bank & Trust, Merrill
Lynch, Pierce, Fenner & Smith, Inc. and UBS Securities are considered to be
regular brokers and dealers of Master Fund.  As of March 31, 1995, Master Tax-
Exempt Fund held no securities of Master Tax-Exempt Fund's regular brokers or
dealers or their parents.


                              INDEPENDENT AUDITORS
                              --------------------

          Ernst & Young LLP, independent auditors, 200 Clarendon Street, Boston,
MA  02116, serve as auditors of the Companies.  The Funds' Financial Highlights
included in the Prospectus and the financial statements for the period ended
March 31, 1995 incorporated by reference in this Statement of Additional
Information have been audited by Ernst & Young LLP for the periods included in
their reports thereon which appear therein.

                                    COUNSEL
                                    -------

          Drinker Biddle & Reath (of which Mr. McConnel, Secretary of the
Companies, is a partner), located at 1345 Chestnut Street, Philadelphia,
Pennsylvania 19107, is counsel to the Companies, and will pass upon the legality
of the Shares offered by the Prospectus.


                    ADDITIONAL INFORMATION CONCERNING TAXES
                    ---------------------------------------

Generally
---------

          The following supplements the tax information contained in the
Prospectus.

          Each of the Funds is treated as a separate corporate entity under the
Internal Revenue Code of 1986, as amended (the "Code"), and intends to qualify
as a regulated investment company.  If, for any reason, a Fund does not qualify
for a taxable year for the special Federal tax treatment afforded regulated
investment companies, such Fund would be subject to Federal tax on all of its
taxable income at regular corporate rates, without any deduction for
distributions to shareholders.  In such event, dividend distributions (whether
or not derived from interest on Municipal Securities) would be taxable as
ordinary income to shareholders to the extent of the Fund's current and
accumulated earnings and profits and would be


                                     -26-
<PAGE>
 
eligible for the dividends received deduction in the case of corporate
shareholders.

          A 4% non-deductible excise tax is imposed on regulated investment
companies that fail to currently distribute an amount equal to specified
percentages of their ordinary taxable income and capital gain net income (excess
of capital gains over capital losses).  The Funds intend to make sufficient
distributions or deemed distributions of their ordinary taxable income and any
capital gain net income prior to the end of each calendar year to avoid
liability for this excise tax.

          Each Fund will be required in certain cases to withhold and remit to
the U.S. Treasury 31% of taxable dividends paid to shareholders who have failed
to provide a correct tax identification number in the manner required, who are
subject to withholding by the Internal Revenue Service for failure properly to
include on their return payments of taxable interest or dividends, or who have
failed to certify to the Fund when required to do so either that they are not
subject to backup withholding or that they are "exempt recipients."

Short-Term Fund
---------------

          The Short-Term Fund is not intended to constitute a balanced
investment program and is not designed for investors seeking capital
appreciation or maximum tax-exempt income irrespective of fluctuations in
principal. Shares of the Short-Term Fund would not be suitable for tax-exempt
institutions and may not be suitable for retirement plans qualified under
Section 401 of the Code, H.R. 10 plans and individual retirement accounts
because such plans and accounts are generally tax-exempt and, therefore, not
only would not gain any additional benefit from the Short-Term Fund dividends
being tax-exempt, but such dividends would be ultimately taxable to the
beneficiaries when distributed to them. In addition, the Short-Term Fund may not
be an appropriate investment for entities which are "substantial users" of
facilities financed by private activity bonds or "related persons" thereof.
"Substantial user" is defined under the Treasury Regulations to include a non-
exempt person who regularly uses a part of such facilities in his trade or
business and whose gross revenues derived with respect to the facilities
financed by the issuance of bonds are more than 5% of the total revenues derived
by all users of such facilities, who occupies more than 5% of the usable area of
such facilities or for whom such facilities or a part thereof were specifically
constructed, reconstructed or acquired. "Related persons" include certain
related natural persons, affiliated corporations, a partnership and its partners
and an S Corporation and its shareholders.

                                     -27-
<PAGE>
 
          In order for the Short-Term Fund to pay exempt-interest dividends for
any taxable year, at least 50% of the aggregate value of the Fund's portfolio
must consist of exempt-interest obligations at the close of each quarter of its
taxable year.  Within 60 days after the close of the taxable year, the Short-
Term Fund will notify its shareholders of the portion of the dividends paid by
the Fund which constitutes an exempt-interest dividend with respect to such
taxable year.  However, the aggregate amount of dividends so designated by the
Short-Term Fund cannot exceed the excess of the amount of interest exempt from
tax under Section 103 of the Code received by the Short-Term Fund during the
taxable year over any amounts disallowed as deductions under Sections 265 and
171(a)(2) of the Code.  The percentage of total dividends paid by the Short-Term
Fund with respect to any taxable year which qualifies as exempt-interest
dividends will be the same for all shareholders receiving dividends from the
Short-Term Fund for such year.

          A percentage of the interest on indebtedness incurred by a shareholder
to purchase or carry the Short-Term Fund's Shares, equal to the percentage of
the total non-capital gain dividends distributed during the shareholders taxable
year that is exempt-interest dividends, is not deductible for Federal income tax
purposes.

          Master Tax-Exempt Fund intends to distribute to shareholders of the
Short-Term Fund any investment company taxable income earned by the Short-Term
Fund for each taxable year.  In general, the Short-Term Fund's investment
company taxable income will be its taxable income (such as taxable interest and
short-term capital gains) subject to certain adjustments and excluding the
excess of any net long-term capital gain for the taxable year over the net
short-term capital loss, if any, for such year.  Such distributions will be
taxable to the shareholders as ordinary income (whether paid in cash or
additional Shares).

                            *          *          *

          The foregoing discussion is based on Federal tax laws and regulations
which are in effect on the date of this Statement of Additional Information;
such laws and regulations may be changed by legislative or administrative
action. Shareholders are advised to consult their tax advisers concerning their
specific situations and the application of state and local taxes.

          The standardized annualized seven-day yields for the Shares of the
Funds are computed separately by determining the net change, exclusive of
capital changes, in the value of a


                                     -28-
<PAGE>
 
hypothetical pre-existing account in the Fund involved, having a balance of one
Share at the beginning of the period, dividing the net change in account value
by the value of the account at the beginning of the period to obtain the base
period return, and multiplying the base period return by (365/7).  The net
change in the value of an account in each of the Funds includes the value of
additional Shares purchased with dividends from the original Share and dividends
declared on both the original Share and any such additional Shares, net of all
fees that are charged to all shareholder accounts and to the particular series
of Shares in proportion to the length of the base period, other than
nonrecurring account or any sales charges.  For any account fees that vary with
the size of the account, the amount of fees charged is computed with respect to
the Fund's mean (or median) account size.  The capital changes to be excluded
from the calculation of the net change in account value are realized gains and
losses from the sale of securities and unrealized appreciation and depreciation.
In addition, each Fund may use effective compound yield quotations for its
Shares computed by adding 1 to the unannualized base period return (calculated
as described above), raising the sums to a power equal to 365 divided by 7, and
subtracting 1 from the results.

          From time to time, in advertisements, sales literature or in reports
to shareholders, the yields of each Money Market Fund's Shares may be quoted and
compared to those of other mutual funds with similar investment objectives and
to stock or other relevant indices.  For example, the yield of such a Fund's
Shares may be compared to the Donoghue's Money Fund average, which is an average
compiled by Donoghue's MONEY FUND REPORT of Holliston, MA 01746, a widely
recognized independent publication that monitors the performance of money market
funds, or to the data prepared by Lipper Analytical Services, Inc., a widely
recognized independent service that monitors the performance of mutual funds.
Advertisements, sales literature or reports to shareholders may from time to
time also include a discussion and analysis of each Fund's performance,
including without limitation, those factors, strategies and techniques that,
together with market conditions and events, materially affected each Fund's
performance.

          The current yields for the Funds' Shares may be obtained by calling
(800) 233-9180.  For the seven-day period ended March 31, 1995, the annualized
yields for Shares of the Money Fund, Government Money Fund, Treasury Money Fund
and Short-Term Fund were 5.69%, 5.62%, 5.30% and 3.64%, respectively, and the
effective yields for Shares of such respective Funds were 5.85%, 5.78%, 5.44%
and 3.71%.

          The "tax-equivalent" yield of the Short-Term Fund is computed by:  (a)
dividing the portion of the yield (calculated as above) that is exempt from
Federal income tax by one minus a


                                     -29-
<PAGE>
 
stated Federal income tax rate and (b) adding that figure to that portion, if
any of the yield that is not exempt from Federal income tax.  Tax-equivalent
yields assume the payment of Federal income taxes at a rate of 31%.

          Based on the foregoing calculation, the annualized tax-equivalent
yield of the Short-Term Fund for the seven-day period ended March 31, 1995 was
5.28%.


                                 MISCELLANEOUS
                                 -------------

          As used in the Prospectus, "assets belonging to a Fund" means the
consideration received upon the issuance of Shares in the Fund, together with
all income, earnings, profits, and proceeds derived from the investment thereof,
including any proceeds from the sale of such investments, any funds or payments
derived from any reinvestment of such proceeds, and a portion of any general
assets of the Company involved not belonging to a particular portfolio of that
Company.  In determining the net asset value of a Fund's Shares, assets
belonging to the Fund are charged with the direct liabilities in respect of that
Fund and with a share of the general liabilities of the Company involved which
are normally allocated in proportion to the relative asset values of the
Company's portfolios at the time of allocation.  Subject to the provisions of
the Companies' Charters, determinations by the Boards of Directors as to the
direct and allocable liabilities, and the allocable portion of any general
assets with respect to a particular Fund, are conclusive.

          As of July 11, 1995, U.S. Trust held of record substantially all of
the outstanding Shares in the Funds, but did not own such Shares beneficially
because it did not have discretion to vote or invest such Shares.

          As of July 11, 1995, the name, address and percentage ownership of
each person, in addition to U.S. Trust, that beneficially owned 5% or more of
the outstanding shares of a Fund

Commercial Paper Ratings
------------------------

          A Standard & Poor's commercial paper rating is a current assessment of
the likelihood of timely payment of debt considered short-term in the relevant
market.  The following summarizes the rating categories used by Standard and
Poor's for commercial paper:

          "A-1" - Issue's degree of safety regarding timely payment is strong.
Those issues determined to possess extremely strong safety characteristics are
denoted "A-1+."

          "A-2" - Issue's capacity for timely payment is satisfactory.  However,
the relative degree of safety is not as high as for issues designated "A-1."

          "A-3" - Issue has an adequate capacity for timely payment.  It is,
however, somewhat more vulnerable to the adverse effects of changes and
circumstances than an obligation carrying a higher designation.

          "B" - Issue has only a speculative capacity for timely payment.

          "C" - Issue has a doubtful capacity for payment.

          "D" - Issue is in payment default.


          Moody's commercial paper ratings are opinions of the ability of
issuers to repay punctually promissory obligations not having an original
maturity in excess of 9 months.  The following summarizes the rating categories
used by Moody's for commercial paper:

          "Prime-1" - Issuer or related supporting institutions are considered
to have a superior capacity for repayment of short-term promissory obligations.
Prime-1 repayment capacity will normally be evidenced by the following
characteristics: leading market positions in well established industries; high
rates of return on funds employed; conservative capitalization structures with
moderate reliance on debt and ample asset protection; broad margins in earning
coverage of fixed financial charges and high internal cash generation; and well
established access to a range of financial markets and assured sources of
alternate liquidity.

                                      A-1
<PAGE>
 
          "Prime-2" - Issuer 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 cited above 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.

          "Prime-3" - Issuer or related supporting institutions have an
acceptable capacity for repayment of short-term promissory obligations.  The
effects of industry characteristics and market composition may be more
pronounced.  Variability in earnings and profitability may result in changes in
the level of debt protection measurements and the requirement for relatively
high financial leverage.  Adequate alternate liquidity is maintained.

          "Not Prime" - Issuer does not fall within any of the Prime rating
categories.

          The three rating categories of Duff & Phelps for investment grade
commercial paper and short-term debt are "D-1," "D-2" and "D-3."  Duff & Phelps
employs three designations, "D-1+," "D-1" and "D-1-," within the highest rating
category.  The following summarizes the rating categories used by Duff & Phelps
for commercial paper:

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

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

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

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

          "D-3" - Debt possesses satisfactory liquidity, and other protection
factors qualify issue as investment grade.  Risk factors are larger and subject
to more variation.  Nevertheless, timely payment is expected.


                                      A-2
<PAGE>
 
          "D-4" - Debt possesses speculative investment characteristics.
Liquidity is not sufficient to ensure against disruption in debt service.
Operating factors and market access may be subject to a high degree of
variation.

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

          Fitch short-term ratings apply to debt obligations that are payable on
demand or have original maturities of up to three years.  The following
summarizes the rating categories used by Fitch for short-term obligations:

          "F-1+" - Securities possess exceptionally strong credit quality.
Issues assigned this rating are regarded as having the strongest degree of
assurance for timely payment.

          "F-1" - Securities possess very strong credit quality.  Issues
assigned this rating reflect an assurance of timely payment only slightly less
in degree than issues rated "F-1+."

          "F-2" - Securities possess good credit quality.  Issues assigned this
rating have a satisfactory degree of assurance for timely payment, but the
margin of safety is not as great as the "F-1+" and "F-1" categories.

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

          "F-S" - Securities possess weak credit quality.  Issues assigned this
rating have characteristics suggesting a minimal degree of assurance for timely
payment and are vulnerable to near-term adverse changes in financial and
economic conditions.

          "D" - Securities are in actual or imminent payment default.

          Fitch may also use the symbol "LOC" with its short-term ratings to
indicate that the rating is based upon a letter of credit issued by a commercial
bank.

          Thomson BankWatch short-term ratings assess the likelihood of an
untimely or incomplete payment of principal or interest of unsubordinated
instruments having a maturity of one year or less which is issued by United
States commercial banks, thrifts and non-bank banks; non-United States banks;
and broker-

                                      A-3

dealers.  The following summarizes the ratings used by Thomson BankWatch:

          "TBW-1" - This designation represents Thomson BankWatch's highest
rating category and indicates a very high degree of likelihood that principal
and interest will be paid on a timely basis.

          "TBW-2" - This designation indicates that while the degree of safety
regarding timely payment of principal and interest is strong, the relative
degree of safety is not as high as for issues rated "TBW-1."

          "TBW-3" - This designation represents the lowest investment grade
category and indicates that while the debt is more susceptible to adverse
developments (both internal and external) than obligations with higher ratings,
capacity to service principal and interest in a timely fashion is considered
adequate.

          "TBW-4" - This designation indicates that the debt is regarded as non-
investment grade and therefore speculative.

          IBCA assesses the investment quality of unsecured debt with an
original maturity of less than one year which is issued by bank holding
companies and their principal bank subsidiaries.  The following summarizes the
rating categories used by IBCA for short-term debt ratings:

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

          "A2" - Obligations are supported by a good capacity for timely
repayment.

          "A3" - Obligations are supported by a satisfactory capacity for timely
repayment.

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

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

Corporate and Municipal Long-Term Debt Ratings
----------------------------------------------

          The following summarizes the ratings used by Standard & Poor's for
corporate and municipal debt:

          "AAA" - This designation represents the highest rating assigned by
Standard & Poor's to a debt obligation and indicates an extremely strong
capacity to pay interest and repay principal.

          "AA" - Debt is considered to have a very strong capacity to pay
interest and repay principal and differs from AAA issues only in small degree.

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

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

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

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

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

                                      A-5
<PAGE>
 
          "CCC" - Debt has a currently identifiable vulnerability to default,
and is dependent upon favorable business, financial and economic conditions to
meet timely payment of interest and repayment of principal.  In the event of
adverse business, financial or economic conditions, it is not likely to have the
capacity to pay interest and repay principal.  The "CCC" rating category is also
used for debt subordinated to senior debt that is assigned an actual or implied
"B" or "B-" rating.

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

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

          "CI" - This rating is reserved for income bonds on which no interest
is being paid.

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

          PLUS (+) OR MINUS (-) - The ratings from "AA" through "CCC" may be
modified by the addition of a plus or minus sign to show relative standing
within the major rating categories.

          "r" - This rating is attached to highlight derivative, hybrid, and
certain other obligations that S & P believes may experience high volatility or
high variability in expected returns due to non-credit risks.  Examples of such
obligations are: securities whose principal or interest return is indexed to
equities, commodities, or currencies; certain swaps and options; and interest
only and principal only mortgage securities.

          The following summarizes the ratings used by Moody's for corporate and
municipal long-term debt:

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

                                      A-6
<PAGE>
 
          "Aa" - Bonds are judged to be of high quality by all standards.
Together with the "Aaa" group they comprise what are generally known as high
grade bonds.  They are rated lower than the best bonds because margins of
protection may not be as large as in "Aaa" securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risks appear somewhat larger than in "Aaa"
securities.

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

          "Baa" - Bonds considered medium-grade obligations, i.e., they are
neither highly protected nor poorly secured.  Interest payments and principal
security appear adequate for the present but certain protective elements may be
lacking or may be characteristically unreliable over any great length of time.
Such bonds lack outstanding investment characteristics and in fact have
speculative characteristics as well.

          "Ba," "B," "Caa," "Ca," and "C" - Bonds that possess one of these
ratings provide questionable protection of interest and principal ("Ba"
indicates some speculative elements; "B" indicates a general lack of
characteristics of desirable investment; "Caa" represents a poor standing; "Ca"
represents obligations which are speculative in a high degree; and "C"
represents the lowest rated class of bonds). "Caa," "Ca" and "C" bonds may be in
default.

          Con. (---) - Bonds for which the security depends upon the completion
of some act or the fulfillment of some condition are rated conditionally.  These
are bonds secured by (a) earnings of projects under construction, (b) earnings
of projects unseasoned in operation experience, (c) rentals which begin when
facilities are completed, or (d) payments to which some other limiting condition
attaches.  Parenthetical rating denotes probable credit stature upon completion
of construction or elimination of basis of condition.

          Moody's applies numerical modifiers 1, 2 and 3 in each generic
classification from "Aa" to "B" in its bond rating system.  The modifier 1
indicates that the issuer 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 issuer ranks at the lower end of its generic rating category.


                                      A-7
<PAGE>
 
          The following summarizes the long-term debt ratings used by Duff &
Phelps for corporate and municipal long-term debt:

          "AAA" - Debt is considered to be of the highest credit quality.  The
risk factors are negligible, being only slightly more than for risk-free U.S.
Treasury debt.

          "AA" - Debt is considered of high credit quality.  Protection factors
are strong.  Risk is modest but may vary slightly from time to time because of
economic conditions.

          "A" - Debt possesses protection factors which are average but
adequate.  However, risk factors are more variable and greater in periods of
economic stress.

          "BBB" - Debt possesses below average protection factors but such
protection factors are still considered sufficient for prudent investment.
Considerable variability in risk is present during economic cycles.

          "BB," "B," "CCC," "DD," and "DP" - Debt that possesses one of these
ratings is considered to be below investment grade.  Although below investment
grade, debt rated "BB" is deemed likely to meet obligations when due.  Debt
rated "B" possesses the risk that obligations will not be met when due.  Debt
rated "CCC" is well below investment grade and has considerable uncertainty as
to timely payment of principal, interest or preferred dividends.  Debt rated
"DD" is a defaulted debt obligation, and the rating "DP" represents preferred
stock with dividend arrearages.

          To provide more detailed indications of credit quality, the "AA," "A,"
"BBB," "BB" and "B" ratings may be modified by the addition of a plus (+) or
minus (-) sign to show relative standing within these major categories.


          The following summarizes the highest four ratings used by Fitch for
corporate and municipal bonds:

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

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


                                      A-8
<PAGE>
 
          "A" - Bonds considered to be investment grade and of high credit
quality.  The obligor's ability to pay interest and repay principal is
considered to be strong, but may be more vulnerable to adverse changes in
economic conditions and circumstances than bonds with higher ratings.

          "BBB" - Bonds considered to be investment grade and of satisfactory
credit quality.  The obligor's ability to pay interest and repay principal is
considered to be adequate.  Adverse changes in economic conditions and
circumstances, however, are more likely to have an adverse impact on these
bonds, and therefore, impair timely payment.  The likelihood that the ratings of
these bonds will fall below investment grade is higher than for bonds with
higher ratings.

          "BB," "B," "CCC," "CC," "C," "DDD," "DD," and "D" -Bonds that possess
one of these ratings are considered by Fitch to be speculative investments.  The
ratings "BB" to "C" represent Fitch's assessment of the likelihood of timely
payment of principal and interest in accordance with the terms of obligation for
bond issues not in default.  For defaulted bonds, the rating "DDD" to "D" is an
assessment of the ultimate recovery value through reorganization or liquidation.

          To provide more detailed indications of credit quality, the Fitch
ratings from and including "AA" to "C" may be modified by the addition of a plus
(+) or minus (-) sign to show relative standing within these major rating
categories.


          IBCA assesses the investment quality of unsecured debt with an
original maturity of more than one year which is issued by bank holding
companies and their principal bank subsidiaries.  The following summarizes the
rating categories used by IBCA for long-term debt ratings:

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

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

          "A" - Obligations for which there is a low expectation of investment
risk.  Capacity for timely repayment of principal and interest is strong,
although adverse changes in business,


                                      A-9
<PAGE>
 
economic or financial conditions may lead to increased investment risk.

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

          "BB," "B," "CCC," "CC," and "C" - Obligations are assigned one of
these ratings where it is considered that speculative characteristics are
present.  "BB" represents the lowest degree of speculation and indicates a
possibility of investment risk developing.  "C" represents the highest degree of
speculation and indicates that the obligations are currently in default.

          IBCA may append a rating of plus (+) or minus (-) to a rating to
denote relative status within major rating categories.

          Thomson BankWatch assesses the likelihood of an untimely repayment of
principal or interest over the term to maturity of long term debt and preferred
stock which are issued by United States commercial banks, thrifts and non-bank
banks; non-United States banks; and broker-dealers.  The following summarizes
the rating categories used by Thomson BankWatch for long-term debt ratings:

          "AAA" - This designation represents the highest category assigned by
Thomson BankWatch to long-term debt and indicates that the ability to repay
principal and interest on a timely basis is very high.

          "AA" - This designation indicates a superior ability to repay
principal and interest on a timely basis with limited incremental risk versus
issues rated in the highest category.

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

          "BBB" - This designation represents Thomson BankWatch's lowest
investment grade category and indicates an acceptable capacity to repay
principal and interest.  Issues rated "BBB" are, however, more vulnerable to
adverse developments (both internal and external) than obligations with higher
ratings.

          "BB," "B," "CCC," and "CC," - These designations are assigned by
Thomson BankWatch to non-investment grade long-term

                                     A-10
<PAGE>
 
debt.  Such issues are regarded as having speculative characteristics regarding
the likelihood of timely payment of principal and interest.  "BB" indicates the
lowest degree of speculation and "CC" the highest degree of speculation.

          "D" - This designation indicates that the long-term debt is in
default.

          PLUS (+) OR MINUS (-) - The ratings from "AAA" through "CC" may
include a plus or minus sign designation which indicates where within the
respective category the issue is placed.


Municipal Note Ratings
----------------------

          A Standard and Poor's rating reflects the liquidity concerns and
market access risks unique to notes due in three years or less.  The following
summarizes the ratings used by Standard & Poor's Ratings Group for municipal
notes:

          "SP-1" - The issuers of these municipal notes exhibit very strong or
strong capacity to pay principal and interest.  Those issues determined to
possess overwhelming safety characteristics are given a plus (+) designation.

          "SP-2" - The issuers of these municipal note exhibit satisfactory
capacity to pay principal and interest.

          "SP-3" - The issuers of these municipal notes exhibit speculative
capacity to pay principal and interest.

          Moody's ratings for state and municipal notes and other short-term
loans are designated Moody's Investment Grade ("MIG") and variable rate demand
obligations are designated Variable Moody's Investment Grade ("VMIG").  Such
ratings recognize the differences between short-term credit risk and long-term
risk.  The following summarizes the ratings by Moody's Investors Service, Inc.
for short-term notes:

          "MIG-1"/"VMIG-1" - Loans bearing this designation are of the best
quality, enjoying strong protection by established cash flows, superior
liquidity support or demonstrated broad-based access to the market for
refinancing.

          "MIG-2"/"VMIG-2" - Loans bearing this designation are of high quality,
with margins of protection ample although not so large as in the preceding
group.

          "MIG-3"/"VMIG-3" - Loans bearing this designation are of favorable
quality, with all security elements accounted for but lacking the undeniable
strength of the preceding grades.


                                     A-11
<PAGE>
 
Liquidity and cash flow protection may be narrow and market access for
refinancing is likely to be less well established.

          "MIG-4"/"VMIG-4" - Loans bearing this designation are of adequate
quality, carrying specific risk but having protection commonly regarded as
required of an investment security and not distinctly or predominantly
speculative.

          "SG" - Loans bearing this designation are of speculative quality and
lack margins of protection.

          Fitch and Duff & Phelps use the short-term ratings described under
Commercial Paper Ratings for municipal notes.

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

          This Statement of Additional Information contains additional
information with respect to the Short-Term Tax-Exempt Securities Fund,
Intermediate-Term Tax-Exempt Fund and Long-Term Tax-Exempt Fund (collectively,
the "Tax-Exempt Funds") of Master Tax-Exempt Fund and the Short-Term Government
Securities Fund, Intermediate-Term Managed Income Fund and Managed Income Fund
of Master Fund (collectively, the "Fixed-Income Funds").  The portfolios are
referred to individually as a "Fund" and collectively as the "Funds"; Master
Tax-Exempt Fund and Master Fund are referred to individually as a "Company" and
collectively as the "Companies".

          For ease of reference, the various Funds are referred to as follows:
Short-Term Tax-Exempt Securities Fund as "Short-Term Tax-Exempt Fund";
Intermediate-Term Tax-Exempt Fund as "IT Tax-Exempt Fund"; Long-Term Tax-Exempt
Fund as "LT Tax-Exempt Fund", Short-Term Government Securities Fund as "ST
Government Fund", and Intermediate-Term Managed Income Fund as "IT Income Fund".

          The following policies and disclosures supplement the Funds'
investment objectives and policies as set forth in the Prospectuses.

Additional Information on Portfolio Instruments
-----------------------------------------------

          Municipal Obligations
          ---------------------

          The Tax-Exempt Funds invest substantially all of their assets in
Municipal Obligations as defined in the Prospectus.  Municipal Obligations
include debt obligations issued by governmental entities to obtain funds for
various public purposes, including the construction of a wide range of public
facilities, the refunding of outstanding obligations, the payment of general
operating expenses, and the extension of loans to public institutions and
facilities.  Private activity bonds that are issued by or on behalf of public
authorities to finance various privately operated facilities are included within
the term "Municipal Obligations" only if the interest paid thereon is exempt
from regular Federal income tax and not treated as a specific tax preference
item under the Federal alternative minimum tax.

          The two principal classifications of Municipal Obligations are
"general obligation" and "revenue" issues, but the Tax-Exempt Funds' portfolios
may include "moral obligation" issues, which are normally issued by special-
purpose authorities.  There are, of course, variations in the quality of
Municipal Obligations, both within a particular classification and between
<PAGE>
 
classifications, and the yields on Municipal Obligations 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 Moody's Investors Service, Inc. ("Moody's") and Standard
& Poor's Ratings Group ("S&P") described in the Prospectus and Appendix A hereto
represent their opinion as to the quality of Municipal Obligations.  It should
be emphasized that these ratings are general and are not absolute standards of
quality, and Municipal Obligations with the same maturity, interest rate, and
rating may have different yields while Municipal Obligations of the same
maturity and interest rate with different ratings may have the same yield.
Subsequent to its purchase by a Fund, an issue of Municipal Obligations may
cease to be rated, or its rating may be reduced below the minimum rating
required for purchase by that Fund.  United States Trust Company of New York,
the Funds' investment adviser ("Investment Adviser" or "U.S. Trust"), will
consider such an event in determining whether a Fund should continue to hold the
obligation.

          The payment of principal and interest on most securities purchased by
the Tax-Exempt Funds will depend upon the ability of the issuers to meet their
obligations.  Each state, the District of Columbia, each of their political
subdivisions, agencies, instrumentalities and authorities, and each multistate
agency of which a state is a member, is a separate "issuer" as that term is used
in this Statement of Additional Information and the Prospectus.  The non-
governmental user of facilities financed by private activity bonds is also
considered to be an "issuer." An issuer's obligations under its Municipal
Obligations 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.  The power or ability of an issuer to
meet its obligations for the payment of interest on and principal of its
Municipal Obligations may be materially adversely affected by litigation or
other conditions.

          Private activity bonds are or have been issued to obtain funds to
provide, among other things, privately operated housing facilities, pollution
control facilities, convention or trade show facilities, mass transit, airport,
port or parking facilities and certain local facilities for water supply, gas,
electricity or sewage or solid waste disposal.  Private activity bonds are also
issued to privately held or publicly owned corporations in the financing of
commercial or industrial facilities.  State and local governments are authorized
in most

                                      -2-
<PAGE>
 
states to issue private activity bonds for such purposes in order to encourage
corporations to locate within their communities.  The principal and interest on
these obligations may be payable from the general revenues of the users of such
facilities.

          Among other instruments, the Tax-Exempt Funds may purchase short-term
General Obligation Notes, Tax Anticipation Notes, Bond Anticipation Notes,
Revenue Anticipation Notes, Tax-Exempt Commercial Paper, Construction Loan Notes
and other forms of short-term loans.  Such instruments are issued with a short-
term maturity in anticipation of the receipt of tax funds, the proceeds of bond
placements or other revenues.  In addition, each Fund may invest in long-term
tax-exempt instruments, such as municipal bonds and private activity bonds, to
the extent consistent with the maturity restrictions applicable to it.

          From time to time, proposals have been introduced before Congress for
the purpose of restricting or eliminating the Federal income tax exemption for
interest on Municipal Obligations.  For example, under the Tax Reform Act of
1986, as amended, interest on certain private activity bonds must be included in
an investor's alternative minimum taxable income, and corporate investors must
treat all tax-exempt interest as an item of tax preference.  Master Tax-Exempt
Fund cannot, of course, predict what legislation may be proposed in the future
regarding the income tax status of interest on Municipal Obligations, or which
proposals, if any, might be enacted.  Such proposals, while pending or if
enacted, might materially adversely affect the availability of Municipal
Obligations for investment by the Tax-Exempt Funds and the liquidity and value
of their portfolios.  In such an event, Master Tax-Exempt Fund would reevaluate
the Funds' investment objectives and policies and consider possible changes in
their structure or possible dissolution.

          Opinions relating to the validity of Municipal Obligations and to the
exemption of interest thereon from Federal income tax are rendered by bond
counsel to the respective issuers at the time of issuance.  Neither Master Tax-
Exempt Fund nor the Investment Adviser will review the proceedings relating to
the issuance of Municipal Obligations or the basis for such opinions.

          The IT Income and Managed Income Funds may, when deemed appropriate by
the Investment Adviser in light of the Funds' investment objective, also invest
in Municipal Obligations.  Although yields on municipal obligations can
generally be expected under normal market conditions to be lower than yields on
corporate and U.S. Government obligations, from time to time municipal
securities have outperformed, on a total return basis, comparable corporate and
Federal debt obligations as a result of prevailing economic, regulatory or other
circumstances.  Dividends paid by the IT Income and Managed Income Funds that
are

                                      -3-
<PAGE>
 
derived from interest on municipal securities would be taxable to the Funds'
shareholders for Federal income tax purposes.

          Insured Municipal Obligations
          -----------------------------

          The Tax-Exempt Funds may purchase Municipal Obligations which are
insured as to timely payment of principal and interest at the time of purchase.
The insurance policies will usually be obtained by the issuer of the bond at the
time of its original issuance.  Bonds of this type will be acquired only if at
the time of purchase they satisfy quality requirements generally applicable to
Municipal Obligations as described in the Prospectus.  Although insurance
coverage for the Municipal Obligations held by the Tax-Exempt Funds reduces
credit risk by insuring that the Funds will receive timely payment of principal
and interest, it does not protect against market fluctuations caused by changes
in interest rates and other factors.  Each Tax-Exempt Fund may invest more than
25% of its net assets in Municipal Obligations covered by insurance policies.

          Repurchase Agreements
          ---------------------

          The repurchase price under the repurchase agreements described in the
Prospectus 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).  Securities subject to
repurchase agreements are held by the Funds' custodian (or sub-custodian) or in
the Federal Reserve/Treasury book-entry system.  Repurchase agreements are
considered loans by a Fund under the Investment Company Act of 1940 (the "1940
Act").

          Securities Lending
          ------------------

          When the ST Government Fund, IT Income Fund and Managed Income Fund
lend their portfolio securities, they continue to receive interest or dividends
on the securities lent and may simultaneously earn interest on the investment of
the cash loan collateral, which will be invested in readily marketable, high-
quality, short-term obligations.  Although voting rights, or rights to consent,
attendant to securities lent pass to the borrower, such loans may be called at
any time and will be called so that the securities may be voted by the pertinent
Fund if a material event affecting the investment is to occur.

          Government Obligations
          ----------------------

          Examples of the types of U.S. Government obligations that may be held
by the Funds include, in addition to U.S. Treasury Bills, the obligations of
Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, the
Federal Housing Administration, Farmers Home Administration, Export-

                                      -4-
<PAGE>
 
Import Bank of the United States, Small Business Administration, Government
National Mortgage Association, Federal National Mortgage Association, General
Services Administration, Student Loan Marketing Association, Central Bank for
Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate
Credit Banks and Maritime Administration.

          When-Issued and Forward Transactions
          ------------------------------------

          When a Fund agrees to purchase securities on a "when-issued" or
forward commitment basis, the custodian will set aside cash or liquid portfolio
securities equal to the amount of the commitment in a separate account.
Normally, the custodian will set aside portfolio securities to satisfy a
purchase commitment and, in such case, the Fund may be required subsequently to
place additional assets in the separate 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 a 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 a Fund will set aside cash or liquid assets to
satisfy its purchase commitments in the manner described, its liquidity and
ability to manage its portfolio might be affected in the event its forward
commitments or commitments to purchase "when-issued" securities ever exceeded
25% of the value of its assets.

          A Fund will purchase securities on a "when-issued" or forward
commitment basis only with the intention of completing the transaction.  If
deemed advisable as a matter of investment strategy, however, a Fund may dispose
of or renegotiate a commitment after it is entered into, and may sell securities
it has committed to purchase before those securities are delivered to the Fund
on the settlement date.  In these cases, the Fund may realize a taxable capital
gain or loss.

          When a Fund engages in "when-issued" or forward commitment
transactions, it relies on the other party to consummate the trade.  Failure of
such other party to do so may result in the Fund incurring a loss or missing an
opportunity to obtain a price considered to be advantageous.

          The market value of the securities underlying a "when-issued" purchase
or a forward commitment to purchase securities and any subsequent fluctuations
in their market value are taken into account when determining the market value
of a Fund starting on the day the Fund agrees to purchase the securities.  The
Fund does not earn interest on the securities it has committed to purchase until
they are paid for and delivered on the settlement date.

                                      -5-
<PAGE>
 
          Stand-By Commitments
          --------------------

          The Managed Income and IT Income Funds and the Tax-Exempt Funds may
acquire "stand-by commitments" with respect to Municipal Obligations held by
them.  Under a "stand-by commitment," a dealer or bank agrees to purchase from a
Fund, at the Fund's option, specified Municipal Obligations at a specified
price.  The amount payable to a Fund upon its exercise of a "stand-by
commitment" is normally (i) the Fund's acquisition cost of the Municipal
Obligations (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.  "Stand-by commitments" are exercisable by a Fund at any
time before the maturity of the underlying Municipal Obligations, and may be
sold, transferred or assigned by the Fund only with the underlying instruments.

          The Managed Income and IT Income Funds and the Tax-Exempt Funds expect
that "stand-by commitments" will generally be available without the payment of
any direct or indirect consideration.  However, if necessary or advisable, a
Fund may pay for a "stand-by commitment" either separately in cash or by paying
a higher price for securities which are acquired subject to the commitment (thus
reducing the yield to maturity otherwise available for the same securities).
Where a Fund has paid any consideration directly or indirectly for a "stand-by
commitment," its cost will be reflected as unrealized depreciation for the
period during which the commitment was held by the Fund.

          The Managed Income and IT Income Funds and the Tax-Exempt Funds intend
to enter into "stand-by commitments" only with banks and broker/dealers which,
in the Investment Adviser's opinion, present minimal credit risks. In evaluating
the creditworthiness of the issuer of a "stand-by commitment," the Investment
Adviser will review periodically the issuer's assets, liabilities, contingent
claims and other relevant financial information.

          Commercial Paper
          ----------------

          Investments by the Funds in commercial paper will consist of issues
that are rated "A-2" or better by S&P or "Prime-2" or better by Moody's.  In
addition, each Fund may acquire unrated commercial paper that is determined by
the Investment Adviser at the time of purchase to be of comparable quality to
rated instruments that may be acquired by the particular Fund.  Each Fund will
generally limit its investments in such unrated commercial paper to 5% of its
total assets.

                                      -6-
<PAGE>
 
          Futures Contracts
          -----------------

          Each Fund may invest in futures contracts (interest rate futures
contracts or municipal bond index futures contracts, as applicable).  Futures
contracts will not be entered into for speculative purposes, but to hedge risks
associated with a Fund's securities investments.  Positions in futures contracts
may be closed out only on an exchange which provides a secondary market for such
futures.  However, there can be no assurance that a liquid secondary market will
exist for any particular futures contract at any specific time.  Thus, it may
not be possible to close a futures position.  In the event of adverse price
movements, a Fund would continue to be required to make daily cash payments to
maintain its required margin.  In such situations, if a Fund has insufficient
cash, it may have to sell portfolio securities to meet daily margin requirements
at a time when it may be disadvantageous to do so.  In addition, a Fund may be
required to make delivery of the instruments underlying futures contracts it
holds.  The inability to close options and futures positions also could have an
adverse impact on a Fund's ability to effectively hedge.

          Successful use of futures by a Fund is also subject to the Investment
Adviser's ability to correctly predict movements in the direction of the market.
For example, if a Fund has hedged against the possibility of a decline in the
market adversely affecting securities held by it and securities prices increase
instead, the Fund will lose part or all of the benefit to the increased value of
its securities which it has hedged because it will have approximately equal
offsetting losses in its futures positions.  In addition, in some situations, if
a Fund has insufficient cash, it may have to sell securities to meet daily
variation margin requirements.  Such sales of securities may be, but will not
necessarily be, at increased prices which reflect the rising market.  A Fund may
have to sell securities at a time when it may be disadvantageous to do so.

          The risk of loss in trading futures contracts in some strategies can
be substantial, due both to the low margin deposits required, and the extremely
high degree of leverage involved in futures pricing.  As a result, a relatively
small price movement in a futures contract may result in immediate and
substantial loss (as well as gain) to the investor.  For example, if at the time
of purchase, 10% of the value of the futures contract is deposited as margin, a
subsequent 10% decrease in the value of the futures contract would result in a
total loss of the margin deposit, before any deduction for the transaction
costs, if the account were then closed out.  A 15% decrease would result in a
loss equal to 150% of the original margin deposit, before any deduction for the
transaction costs, if the contract were closed out.  Thus, a purchase or sale of
a futures contract may

                                      -7-
<PAGE>
 
result in losses in excess of the amount invested in the contract.

          Utilization of futures transactions by a Fund involves the risk of
loss by a Fund of margin deposits in the event of bankruptcy of a broker with
whom the Fund has an open position in a futures contract or related option.

          Most futures exchanges limit the amount of fluctuation permitted in
futures contract prices during a single trading day.  The daily limit
establishes the maximum amount that the price of a futures contract may vary
either up or down from the previous day's settlement price at the end of a
trading session.  Once the daily limit has been reached in a particular type of
contract, no trades may be made on that day at a price beyond that limit.  The
daily limit governs only price movement during a particular trading day and
therefore does not limit potential losses, because the limit may prevent the
liquidation of unfavorable positions.  Futures contract prices have occasionally
moved to the daily limit for several consecutive trading days with little or no
trading, thereby preventing prompt liquidation of futures positions and
subjecting some futures traders to substantial losses.

          The trading of futures contracts is also subject to the risk of
trading halts, suspensions, exchange or clearing house equipment failures,
government intervention, insolvency of a brokerage firm or clearing house or
other disruptions of normal trading activity, which could at times make it
difficult or impossible to liquidate existing positions or to recover excess
variation margin payments.

Additional Investment Limitations
---------------------------------

          In addition to the investment limitations disclosed in the Prospectus,
the Funds are subject to the investment limitations enumerated below.
Fundamental investment limitations may be changed with respect to a Fund only by
a vote of the holders of a majority of such Fund's outstanding Shares (as
defined under "Miscellaneous" in the Prospectuses).  However, investment
limitations which are "operating policies" with respect to a Fund may be changed
by Master Fund's or Master Tax-Exempt Fund's Board of Directors upon reasonable
notice to investors.

          The following investment limitations are fundamental with respect to
each Fund.  No Fund may:

          1.  Act as an underwriter of securities within the meaning of the
Securities Act of 1933, except to the extent that the purchase of Municipal
Obligations or other securities directly from the issuer thereof in accordance
with the Tax-

                                      -8-
<PAGE>
 
Exempt Funds' investment objectives, policies, and limitations may be deemed to
be underwriting; and except insofar as the Managed Income Fund might be deemed
to be an underwriter upon disposition of certain portfolio securities acquired
within the limitation on purchases of restricted securities;

          2.  Purchase or sell real estate, except that each Tax-Exempt Fund may
invest in Municipal Obligations secured by real estate or interests therein, and
the Managed Income and Intermediate-Term Managed Income Funds may purchase
securities of issuers which deal in real estate and may purchase securities
which are secured by interests in real estate; and

          3.  Issue any senior securities, except insofar as any borrowing by
each Fund in accordance with its investment limitations might be considered to
be the issuance of a senior security; provided that each Fund may enter into
futures contracts and futures options.

          The following investment limitations are fundamental with respect to
the IT Tax-Exempt, LT Tax-Exempt and Managed Income Funds, but are operating
policies with respect to the Short-Term Tax-Exempt, ST Government and IT Income
Funds.  The Funds may not:

          4.  Purchase securities on margin, make short sales of securities, or
maintain a short position; provided that each Fund may enter into futures
contracts and futures options; and

          5.  Write or sell puts, calls, straddles, spreads, or combinations
thereof; provided that each Fund may enter into futures contracts and futures
options.

          The following investment limitation is fundamental with respect to
each Tax-Exempt Fund.  A Tax-Exempt Fund may not:

          6.  Make loans, except that each Tax-Exempt Fund may purchase or hold
debt obligations in accordance with its investment objective, policies, and
limitations.

          The following investment limitations are fundamental with respect to
the IT Tax-Exempt and LT Tax-Exempt Funds, but are operating policies with
respect to the Short-Term Tax-Exempt Fund.  A Tax-Exempt Fund may not:

          7.  Invest in industrial revenue bonds where the payment of principal
and interest are the responsibility of a company (including its predecessors)
with less than three years of continuous operation; and

          8.  Purchase securities of other investment companies (except as part
of a merger, consolidation or reorganization or

                                      -9-
<PAGE>
 
purchase of assets approved by the Fund's shareholders), provided that a Fund
may purchase shares of any registered, open-end investment company, if
immediately after any such purchase, the Fund does not (a) own more than 3% of
the outstanding voting stock of any one investment company, (b) invest more than
5% of the value of its total assets in the securities of any one investment
company, or (c) invest more than 10% of the value of its total assets in the
aggregate in securities of investment companies.

          The following investment limitations are fundamental with respect to
the Managed Income Fund, but are operating policies with respect to the IT
Income and ST Government Funds. A Fixed-Income Fund may not:

          9.  Invest in companies for the purpose of exercising management or
control;

          10.  Invest more than 5% of its total assets in securities issued by
companies which, together with any predecessor, have been in continuous
operation for fewer than three years;

          11.  Purchase foreign securities; provided that subject to the limit
described below, the IT Income and Managed Income Funds may purchase (a) dollar-
denominated debt obligations issued by foreign issuers, including foreign
corporations and governments, by U.S. corporations outside the United States in
an amount not to exceed 25% of its total assets at time of purchase; and (b)
certificates of deposit, bankers' acceptances, or other similar obligations
issued by domestic branches of foreign banks, or foreign branches of U.S. banks,
in an amount not to exceed 20% of its total net assets; and

          12.  Acquire any other investment company or investment company
security, except in connection with a merger, consolidation, reorganization, or
acquisition of assets or where otherwise permitted by the 1940 Act.

          The following investment limitation is fundamental with respect to the
IT Tax-Exempt, LT Tax-Exempt and Managed Income Funds.  The IT Tax-Exempt, LT
Tax-Exempt and Managed Income Funds may not:

          13.  Purchase or sell commodity futures contracts, or invest in oil,
gas, or mineral exploration or development programs; provided that the Funds may
enter into futures contracts and futures options.

          The following investment limitation is fundamental with respect to the
Short-Term Tax-Exempt, ST Government and IT Income

                                     -10-
<PAGE>
 
Funds.  The Short-Term Tax-Exempt, ST Government and IT Income Funds may not:

          14.  Purchase or sell commodities or commodity futures contracts, or
invest in oil, gas, or mineral exploration or development programs; provided
that the Funds may enter into futures contracts and futures options.

                            *          *          *

          For the purpose of Investment Limitation No. 2, the prohibition of
purchases of real estate includes acquisition of limited partnership interests
in partnerships formed with a view toward investing in real estate, but does not
prohibit purchases of shares in real estate investment trusts.  The Funds do not
currently intend to invest in real estate investment trusts.

          In addition to the above investment limitations, Master Fund currently
intends to limit the IT Income and Managed Income Funds' investments in warrants
so that, valued at the lower of cost or market value, they do not exceed 5% of a
Fund's net assets.  Included within that amount, but not to exceed 2% of the
value of the IT Income or Managed Income Fund's net assets, may be warrants
which are not listed on the New York or American Stock Exchange.  For the
purpose of this limitation, warrants acquired by the IT Income or Managed Income
Fund in units or attached to securities will be deemed to be without value.

          The IT Tax-Exempt, LT Tax-Exempt and Managed Income Funds may not
purchase or sell commodities.

          The Funds' transactions in futures contracts and futures options
(including the margin posted by the Funds in connection with such transactions)
are excluded from the Funds' prohibitions:  against the purchase of securities
on margin, short sales of securities and the maintenance of a short position;
the issuance of senior securities; writing or selling puts, calls, straddles,
spreads, or combinations thereof; and the mortgage, pledge or hypothecation of
the Funds' assets.

          If a percentage limitation is satisfied at the time of investment, a
later increase or decrease in such percentage resulting from a change in value
of a Fund's portfolio securities will not constitute a violation of such
limitation.

          In order to permit the sale of Shares in certain states, Master Fund
may make other commitments more restrictive than the investment policies and
limitations described above and in the Prospectus.  Should the Companies
determine that any such commitment is no longer in the Funds' best interests,
they will revoke the commitment by terminating sales of the Shares to investors
residing in the state involved.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION
                 ----------------------------------------------

          As stated in the Prospectus, the sales load described above will not
be applicable to: (a) purchases of Shares by customers of the Investment Adviser
or its affiliates; (b) trust, agency or custodial accounts opened through the
trust department of a bank, trust company or thrift institution, provided that
appropriate notification of such status is given at the time of investment; (c)
companies, corporations and partnerships (excluding full service broker/dealers
and financial planners, registered investment advisers and depository
institutions not covered by the exemptions in (d) and (e) below); (d) financial
planners and registered investment advisers not affiliated with or clearing
purchases through full service broker/dealers; (e) purchases of Shares by
depository institutions for their own account as principal; (f) exchange
transactions (described below under "Investor Programs -- Exchange Privilege")
where the Shares being exchanged were acquired in connection with the
distribution of assets held in trust, agency or custodial accounts maintained
with the trust department of a bank; (g) corporate/business retirement plans
(such as 401(k), 403(b)(7), 457 and Keogh accounts) sponsored by the Distributor
and IRA accounts sponsored by the Investment Adviser; (h) company-sponsored
employee pension or retirement plans making direct investments in the Funds; (i)
purchases of Shares by officers, trustees, directors, employees, former
employees and retirees of the Companies, the Investment Adviser, the Distributor
or of any direct or indirect affiliate of any of them; (j) purchases of Shares
by all beneficial shareholders of the Companies as of May 22, 1989; (k)
purchases of Shares by investment advisers registered under the Investment
Advisers Act of 1940 for their customers through an omnibus account established
with United States Trust Company of New York; (l) purchases of Shares by
directors, officers and employees of brokers and dealers selling shares pursuant

who are members of groups services by USAffinity Investment Limited Partnership;
and (n) customers of certain financial institutions who purchase Shares through
a registered representative of UST Financial Services Corp. on the premises of
their financial institutions.  In addition, no sales load is charged on the
reinvestment of dividends or distributions or in connection with certain share
exchange transactions. Investors who have previously redeemed shares in a
portfolio of Master Fund or Master Tax-Exempt Fund on which a sales load has
been paid

                                     -13-
<PAGE>
 
also have a one-time privilege of purchasing shares of another portfolio of
either Company at net asset value without a sales charge, provided that such
                                                          --------          
privilege will apply only to purchases made within 30 calendar days from the
date of redemption and only with respect to the amount of the redemption.

          For the fiscal years ended March 31, 1995, 1994 and 1993, total sales
charges paid by shareholders:  for the IT Tax-Exempt Fund were $17,776, $8,588
and $15,256, respectively; for the LT Tax-Exempt Fund were $4,088, $16,720 and
$22,984, respectively; for the Managed Income Fund were $973, $17,120 and
$24,570, respectively.  Of these respective amounts, UST Distributors, Inc., the
Funds' former distributor, retained $431, $6,693 and $13,214 with respect to the
IT Tax-Exempt Fund; $3,188, $9,491 and $11,296 with respect to the LT Tax-Exempt
Fund; and $973, $14,297 and $16,204 with respect to the Managed Income Fund.
Total sales charges paid by shareholders of the Short-Term Tax-Exempt, ST
Government and IT Income Funds for the fiscal years ended March 31, 1995 and
1994 were $20 and $42,285; $1 and $11,744; and $815 and $741, respectively.  Of
these respective amounts, UST Distributors, Inc., the Funds' former distributor,
retained $20 and $27,165 with respect to the Short-Term Tax-Exempt Fund; $1 and
$9,788 with respect to the ST Government Fund; and $815 and $660 with respect to
the IT Income Fund.  The balance was paid to selling dealers.  Shareholders of
the Short-Term Tax-Exempt, ST Government and IT Income Funds paid no sales
charges for the period from December 31, 1992 (commencement of operations) to
March 31, 1993.

          The Companies may suspend the right of redemption or postpone the date
of payment for Shares for more than seven days during any period when (a)
trading on the New York Stock Exchange (the "Exchange") is restricted by
applicable rules and regulations of the Securities and Exchange Commission; (b)
the Exchange is closed for other than customary weekend and holiday closings;
(c) the Securities and Exchange Commission has by order permitted such
suspension; or (d) an emergency exists as determined by the Securities and
Exchange Commission.

          In the event that Shares are redeemed in cash at their net asset
value, a shareholder may receive in payment for such Shares an amount that is
more or less than his original investment due to changes in the market prices of
that Fund's portfolio securities.

          Under limited circumstances, the Companies may accept securities as
payment for Shares.  Securities acquired in this manner will be limited to
securities issued in transactions involving a bona fide reorganization or
                                              ---------                  
statutory merger, or will be limited to other securities (except for municipal
debt securities issued by state political subdivisions or their agencies or
instrumentalities) that: (a) meet the investment

                                     -14-
<PAGE>
 
objective and policies of any Fund acquiring such securities; (b) are acquired
for investment and not for resale; (c) are liquid securities that are not
restricted as to transfer either by law or liquidity of market; and (d) have a
value that is readily ascertainable (and not established only by evaluation
procedures) as evidenced by a listing on the American Stock Exchange, New York
Stock Exchange or NASDAQ, or as evidenced by their status as U.S. Government
securities, bank certificates of deposit, banker's acceptances, corporate and
other debt securities that are actively traded, money market securities and
other similar securities with a readily ascertainable value.


                               INVESTOR PROGRAMS
                               -----------------

Systematic Withdrawal Plan
--------------------------

          An Investor who owns Shares with a value of $10,000 or more may begin
a Systematic Withdrawal Plan.  The withdrawal can be on a monthly, quarterly,
semiannual or annual basis.  There are four options for such systematic
withdrawals.  The Investor may request:

     (1)  A fixed-dollar withdrawal;

     (2)  A fixed-share withdrawal;

     (3)  A fixed-percentage withdrawal (based on the current value of the
          account); or

     (4)  A declining-balance withdrawal.

Prior to participating in a Systematic Withdrawal Plan, the Investor must
deposit any outstanding certificates for Shares with Mutual Funds Service
Company, the Funds' sub-transfer agent.  Under this Plan, dividends and
distributions are automatically reinvested in additional Shares.  Amounts paid
to Investors under this Plan should not be considered as income.  Withdrawal
payments represent proceeds from the sale of Shares, and there will be a
reduction of the shareholder's equity in the Fund involved if the amount of the
withdrawal payments exceeds the dividends and distributions paid on the Shares
and the appreciation of the Investor's investment in the Fund.  This in turn may
result in a complete depletion of the shareholder's investment.  An Investor may
not participate in a program of systematic investing in a Fund while at the same
time participating in the Systematic Withdrawal Plan with respect to an account
in that Fund.

                                     -15-
<PAGE>
 
Exchange Privilege
------------------

          Investors and Customers of Shareholder Organizations may exchange
Shares having a value of at least $500 for Shares of any other portfolio of the
Companies.  Shares may be exchanged by wire, telephone or mail and must be made
to accounts of identical registration.  There is no exchange fee imposed by the
Companies.  The Companies may modify or terminate the exchange program at any
time upon 60 days' written notice to shareholders, and may reject any exchange
request.  In order to prevent abuse of this privilege to the disadvantage of
other shareholders, the Companies reserve the right to limit the number of
exchange requests of Investors and Customers of Shareholder Organizations to no
more than six per year.

          For Federal income tax purposes, exchanges are treated as sales on
which the shareholder will realize a gain or loss, depending upon whether the
value of the Shares to be given up in exchange is more or less than the basis in
such Shares at the time of the exchange.  Generally, a shareholder may include
sales loads incurred upon the purchase of Shares in his or her tax basis for
such Shares for the purpose of determining gain or loss on a redemption,
transfer or exchange of such Shares.  However, if the shareholder effects an
exchange of Shares for shares of another portfolio of the Companies within 90
days of the purchase and is able to reduce the sales load applicable to the new
shares (by virtue of the Companies' exchange privilege), the amount equal to
such reduction may not be included in the tax basis of the shareholder's
exchanged Shares but may be included (subject to the limitation) in the tax
basis of the new shares.

Other Investor Programs
-----------------------

          As described in the Prospectus, Shares of the Funds may be purchased
in connection with the Automatic Investment Program.  Shares of the Managed
Income, IT Income and ST Government Funds may also be purchased in connection
with certain Retirement Programs.


                          DESCRIPTION OF CAPITAL STOCK
                          ----------------------------

          Master Fund's Charter authorizes its Board of Directors to issue up to
thirty-five billion full and fractional shares of capital stock; Master Tax-
Exempt Fund's Charter authorizes its Board of Directors to issue up to fourteen
billion full and fractional shares of capital stock.  Both Charters authorize
the respective Boards of Directors to classify or reclassify any unissued shares
of the respective Companies into one or more additional classes or series by
setting or changing in any one or more respects their respective preferences,
conversion or other rights, voting powers, restrictions, limitations as to
dividends,

                                     -16-
<PAGE>
 
qualifications, and terms and conditions of redemption.  The Prospectus
describes the classes of shares into which the Companies' authorized capital is
currently classified.

          Shares have no preemptive rights and only such conversion or exchange
rights as the Boards of Directors may grant in their discretion.  When issued
for payment as described in the Prospectus, Shares will be fully paid and non-
assessable.  In the event of a liquidation or dissolution of a Fund,
shareholders of that Fund are entitled to receive the assets available for
distribution belonging to that Fund and a proportionate distribution, based upon
the relative asset values of the portfolios of the Company involved, of any
general assets of that Company not belonging to any particular portfolio of that
Company which are available for distribution.  In the event of a liquidation or
dissolution of either Company, shareholders of such Company will be entitled to
the same distribution process.

          Shareholders of the Companies are entitled to one vote for each full
share held, and fractional votes for fractional shares held, and will vote in
the aggregate and not by class, except as otherwise required by the 1940 Act or
other applicable law or when the matter to be voted upon affects only the
interests of the shareholders of a particular class.  Voting rights are not
cumulative and, accordingly, the holders of more than 50% of the aggregate of a
Company's outstanding shares may elect all of that Company's directors,
regardless of the votes of other shareholders.

          Rule 18f-2 under the 1940 Act provides that any matter required to be
submitted to the holders of the outstanding voting securities of an investment
company such as each Company shall not be deemed to have been effectively acted
upon unless approved by the holders of a majority of the outstanding shares of
each portfolio affected by the matter.  A portfolio is affected by a matter
unless it is clear that the interests of each portfolio in the matter are
substantially identical or that the matter does not affect any interest of the
portfolio.  Under the Rule, the approval of an investment advisory agreement or
any change in a fundamental investment policy would be effectively acted upon
with respect to a portfolio only if approved by a majority of the outstanding
shares of such portfolio.  However, the Rule also provides that the ratification
of the appointment of independent public accountants, the approval of principal
underwriting contracts, and the election of directors may be effectively acted
upon by shareholders of each Company voting without regard to class.

          The Companies' Charters authorize the Boards of Directors, without
shareholder approval (unless otherwise required by applicable law), to (a) sell
and convey the assets of a Fund to another management investment company for
consideration

                                     -17-
<PAGE>
 
which may include securities issued by the purchaser and, in connection
therewith, to cause all outstanding Shares of the Fund involved to be redeemed
at a price which is equal to their net asset value and which may be paid in cash
or by distribution of the securities or other consideration received from the
sale and conveyance; (b) sell and convert a Fund's assets into money and, in
connection therewith, to cause all outstanding Shares to be redeemed at their
net asset value; or (c) combine the assets belonging to a Fund with the assets
belonging to another portfolio of the Company involved, if the Board of
Directors reasonably determines that such combination will not have a material
adverse effect on shareholders of any portfolio participating in such
combination, and, in connection therewith, to cause all outstanding shares of
any portfolio to be redeemed at their net asset value or converted into shares
of another class of the Company's capital stock at net asset value.  The
exercise of such authority by the Boards of Directors will be subject to the
provisions of the 1940 Act, and the Boards of Directors will not take any action
described in this paragraph unless the proposed action has been disclosed in
writing to the particular Fund's shareholders at least 30 days prior thereto.

          Notwithstanding any provision of Maryland law requiring a greater vote
of the Companies' Common Stock (or of the Shares of a Fund voting separately as
a class) in connection with any corporate action, unless otherwise provided by
law (for example, by Rule 18f-2, discussed above) or by the Companies' Charters,
the Companies may take or authorize such action upon the favorable vote of the
holders of more than 50% of the outstanding Common Stock of the particular
Company voting without regard to class.

a written report of the amounts expended under the Company's agreements with
Service Organizations and the purposes for which the expenditures were made.  In
addition, the arrangements with Service Organizations will be approved annually
by a majority of each Company's directors, including a majority of the directors
who are not "interested persons" of the Company as defined in the 1940 Act and
have no direct or indirect financial interest in such arrangements (the
"Disinterested Directors").

          Any material amendment to a Company's arrangements with Service
Organizations must be approved by a majority of the Company's Board of Directors
(including a majority of the Disinterested Directors).  So long as the
Companies' arrangements with Service Organizations are in effect, the selection
and

                                     -24-
<PAGE>
 
nomination of the members of the Companies' Boards of Directors who are not
"interested persons" (as defined in the 1940 Act) of the Companies will be
committed to the discretion of such non-interested Directors.

          For the fiscal years ended March 31, 1995 and 1994, payments to
Service Organizations under the Plans totalled $12,678 and $615, $87,815 and
$6,676, $27,140 and $1,779, $4,466 and $119, $8,274 and $439, and $28,171 and
$1,537 with respect to the Short-Term Tax-Exempt, IT Tax-Exempt, LT Tax-Exempt,
ST Government, IT Income and Managed Income Funds, respectively.  Of these
respective amounts, $11,475 and $615, $74,979 and $4,947, $25,075 and $1,779,
$3,649 and $119, $8,041 and $439, and $20,247 and $965 were paid to affiliates
of U.S. Trust with respect to the Short-Term Tax-Exempt, IT Tax-Exempt, LT Tax-
Exempt, ST Government, IT Income and Managed Income Funds, respectively.

Expenses
--------

          Except as otherwise noted, the Investment Adviser and the
Administrators bear all expenses in connection with the performance of their
advisory and administrative services.  The Funds bear the expenses incurred in
their operations.  Expenses of the Funds include: taxes; interest; fees
(including fees paid to the Companies' Directors and officers who are not
affiliated with the Distributor or the Administrators); SEC fees; state
securities qualification fees; costs of preparing and printing prospectuses for
regulatory purposes and for distribution to shareholders; advisory,
administration and administrative servicing fees; charges of the custodian,
transfer agent and dividend disbursing agent; certain insurance premiums;
outside auditing and legal expenses; cost of independent pricing service; costs
of shareholder reports and meetings; and any extraordinary expenses.  The Funds
also pay for any brokerage fees and commissions in connection with the purchase
of portfolio securities.

          If the expenses borne by a Fund in any fiscal year exceed expense
limitations imposed by applicable state securities regulations, the Investment
Adviser and the Administrators will reimburse such Fund for a portion of any
such excess to the extent required by such regulations in proportion to the fees
received by them in such year up to the amount of fees payable to them,
provided, however, to the extent required by such state regulations, the
Investment Adviser and the Administrators have agreed to effect such
reimbursement regardless of the fees payable to them.  The amounts of the above
reimbursements, if any, will be estimated, reconciled and paid on a monthly
basis.  To the Companies' knowledge, of the applicable expense limitations in
effect on the date of this Statement of Additional Information, none is more
restrictive than the following: 2 1/2% of the first $30 million of average
annual net assets, 2% of the

                                     -25-
<PAGE>
 
next $70 million of average annual net assets and l 1/2% of average annual net
assets in excess of $100 million.

Custodian and Transfer Agent
----------------------------

          United States Trust Company of New York also serves as custodian of
the Funds' assets.  Under the custodian agreements, U.S. Trust has agreed to (i)
maintain a separate account or accounts for each of the Funds; (ii) make
receipts and disbursements of money on behalf of the Funds; (iii) collect and
receive income and other payments and distributions on account of the Funds'
portfolio securities; (iv) respond to correspondence from securities brokers and
others relating to its duties; (v) maintain certain financial accounts and
records; and (vi) make periodic reports to the Companies concerning the Funds'
operations.  U.S. Trust is entitled to monthly fees for furnishing custodial
services according to the following fee schedule: on the face value of debt
securities and the market value of equities, a fee at the annual rate of .05%;
on issues held, $50.00 for each physical issue held, $25.00 for each book-entry
issue held, and 1/4 of 1% of market value for each foreign issue held; on
transactions, $25.00 for each physical transaction, $15.00 for each book-entry
transaction, and $50.00 for each foreign security transaction.  In addition,
U.S. Trust is entitled to reimbursement for its out-of-pocket expenses in
connection with the above services.

          U.S. Trust also serves as the Funds' transfer agent and dividend
disbursing agent.  In such capacity, U.S. Trust has agreed to (i) issue and
redeem Shares; (ii) address and mail all communications by the Funds to their
shareholders, including reports to shareholders, dividend and distribution
notices, and proxy materials for their meetings of shareholders; (iii) respond
to correspondence by shareholders and others relating to its duties; (iv)
maintain shareholder accounts; and (v) make periodic reports to the Companies
concerning the Funds' operations.  For its transfer agency, dividend disbursing,
and subaccounting services, U.S. Trust is entitled to receive $15.00 per annum
per account and subaccount.  In addition, U.S. Trust is entitled to be
reimbursed for its out-of-pocket expenses for the cost of forms, postage,
processing purchase and redemption orders, handling of proxies, and other
similar expenses in connection with the above services.

          U.S. Trust may, at its own expense, open and maintain custody accounts
with respect to the Funds with other banks or trust companies, and may delegate
its transfer agency obligations to another transfer agent registered or
qualified under applicable law, provided that U.S. Trust shall remain liable for
the performance of all of its custodial and transfer agency duties under the
Custodian and Transfer Agency Agreements, notwithstanding any delegation.
Pursuant to this provision in

                                     -26-
<PAGE>
 
the agreements, U.S. Trust has entered into a sub-transfer agency arrangement
with MFSC, an affiliate of U.S. Trust, with respect to accounts of shareholders
who are not Customers of U.S. Trust.  For the services provided by MFSC, U.S.
Trust has agreed to pay MFSC $15.00 per annum per account or subaccount plus
out-of-pocket expenses.  MFSC receives no fee directly from the Companies for
any of its sub-transfer agency services.


                             PORTFOLIO TRANSACTIONS
                             ----------------------

          Subject to the general control of the Companies' Boards of Directors,
the Investment Adviser is responsible for, makes decisions with respect to and
places orders for all purchases and sales of portfolio securities of each of the
Funds.  Purchases and sales of portfolio securities will usually be principal
transactions without brokerage commissions.

          The Funds may engage in short-term trading to achieve their investment
objectives.  Portfolio turnover may vary greatly from year to year as well as
within a particular year.  It is expected that the Funds' turnover rates may
remain higher than those of many other investment companies with similar
investment objectives and policies.  However, since brokerage commissions are
not normally paid on instruments purchased by the Funds, portfolio turnover is
not expected to have a material effect on the net income of any of the Funds.
The Funds' portfolio turnover rate may also be affected by cash requirements for
redemptions of Shares and by regulatory provisions which enable the Funds to
receive certain favorable tax treatment.  Portfolio turnover will not be a
limiting factor in making portfolio decisions.  See "Financial Highlights" in
the Funds' prospectuses for the Funds' portfolio turnover rates.

          Securities purchased and sold by the Funds are generally traded in the
over-the-counter market on a net basis (i.e., without commission) through
dealers, or otherwise involve transactions directly with the issuer of an
instrument.  The cost of securities purchased from underwriters includes an
underwriting commission or concession, and the prices at which securities are
purchased from and sold to dealers include a dealer's mark-up or markdown.  With
respect to over-the-counter transactions, the Funds, where possible, will deal
directly with dealers who make a market in the securities involved, except in
those situations where better prices and execution are available elsewhere.

          The Investment Advisory Agreements between the Companies and the
Investment Adviser provide that, in executing portfolio transactions and
selecting brokers or dealers, the Investment Adviser will seek to obtain the
best net price and the most favorable execution.  The Investment Adviser shall
consider

                                     -27-
<PAGE>
 
factors it deems relevant, including the breadth of the market in the security,
the price of the security, the financial condition and execution capability of
the broker or dealer and whether such broker or dealer is selling shares of the
Companies, and the reasonableness of the commission, if any, for the specific
transaction and on a continuing basis.

          In addition, the Investment Advisory Agreements authorize the
Investment Adviser, to the extent permitted by law and subject to the review of
the Companies' Boards of Directors from time to time with respect to the extent
and continuation of the policy, to cause the Funds to pay a broker which
furnishes brokerage and research services a higher commission than that which
might be charged by another broker for effecting the same transaction, provided
that the Investment Adviser determines in good faith that such commission is
reasonable in relation to the value of the brokerage and research services
provided by such broker, viewed in terms of either that particular transaction
or the overall responsibilities of the Investment Adviser to the accounts as to
which it exercises investment discretion.  Such brokerage and research services
might consist of reports and statistics on specific companies or industries,
general summaries of groups of stocks and their comparative earnings, or broad
overviews of the stock market and the economy.

          Supplementary research information so received is in addition to and
not in lieu of services required to be performed by the Investment Adviser and
does not reduce the investment advisory fee payable by the Funds.  Such
information may be useful to the Investment Adviser in serving the Funds and
other clients and, conversely, supplemental information obtained by the
placement of business of other clients may be useful to the Investment Adviser
in carrying out its obligations to the Funds.

          Portfolio securities will not be purchased from or sold to the
Investment Adviser, the Distributor, or any affiliated person of either of them
(as such term is defined in the 1940 Act) acting as principal, except to the
extent permitted by the Securities and Exchange Commission.

          Investment decisions for the Funds are made independently from those
for other investment companies, common trust funds and other types of funds
managed by the Investment Adviser.  Such other investment companies and funds
may also invest in the same securities as the Funds.  When a purchase or sale of
the same security is made at substantially the same time on behalf of the Funds
and another investment company or common trust fund, the transaction will be
averaged as to price, and available investments allocated as to amount, in a
manner which the Investment Adviser believes to be equitable to the Funds and
such other investment company or common trust fund.  In some instances, this
investment procedure may adversely affect the

                                     -28-
<PAGE>
 
price paid or received by the Funds or the size of the position obtained by the
Funds.  To the extent permitted by law, the Investment Adviser may aggregate the
securities to be sold or purchased for the Funds with those to be sold or
purchased for other investment companies or common trust funds in order to
obtain best execution.

          The Companies are required to identify any securities of their regular
brokers or dealers (as defined in Rule 10b-1 under the 1940 Act) or their
parents held by the Companies as of the close of their most recent fiscal year.
As of March 31, 1995 none of the Funds held any securities of Master Fund's or
Master Tax-Exempt Fund's regular brokers or dealers or their parents.


                              INDEPENDENT AUDITORS
                              --------------------

          Ernst & Young LLP, independent auditors, 200 Clarendon Street, Boston,
MA 02116, serve as auditors of the Companies.  The Funds' Financial Highlights
included in the Prospectus and the financial statements for the period ended
March 31, 1995 incorporated by reference in this Statement of Additional
Information have been audited by Ernst & Young LLP for the periods included in
their reports thereon which appear therein.


                                    COUNSEL
                                    -------

          Drinker Biddle & Reath (of which Mr. McConnel, Secretary of the
Companies, is a partner), Philadelphia National Bank Building, 1345 Chestnut
Street, Philadelphia, Pennsylvania 19107-3496, is counsel to the Companies and
will pass upon the legality of the Shares offered by the Prospectuses.


                    ADDITIONAL INFORMATION CONCERNING TAXES
                    ---------------------------------------

Generally
---------

          The following supplements the tax information contained in the
Prospectus.

          Each of the Funds is treated as a separate corporate entity under the
Internal Revenue Code of 1986, as amended (the "Code"), and intends to qualify
as a regulated investment company.  If, for any reason, a Fund does not qualify
for a taxable year for the special Federal tax treatment afforded regulated
investment companies, such Fund would be subject to Federal tax on all of its
taxable income at regular corporate rates, without any deduction for
distributions to shareholders. In such event, dividend distributions (whether or
not derived from interest on Municipal Securities) would be taxable as

                                     -29-
<PAGE>
 
ordinary income to shareholders to the extent of the Fund's current and
accumulated earnings and profits and would be eligible for the dividends
received deduction in the case of corporate shareholders.

          A Fund will designate any distribution of the excess of net long-term
capital gain over net short-term capital loss as a capital gain dividend in a
written notice mailed to shareholders within 60 days after the close of the
Fund's taxable year.  Shareholders should note that, upon the sale or exchange
of Shares, if the shareholder has not held such Shares for at least six months,
any loss on the sale or exchange of those Shares will be treated as long-term
capital loss to the extent of the capital gain dividends received with respect
to the Shares.


          A 4% non-deductible excise tax is imposed on regulated investment
companies that fail to currently distribute an amount equal to specified
percentages of their ordinary taxable income and capital gain net income (excess
of capital gains over capital losses).  Each Fund intends to make sufficient
distributions or deemed distributions of their ordinary taxable income and any
capital gain net income prior to the end of each calendar year to avoid
liability for this excise tax.

          Each Fund will be required in certain cases to withhold and remit to
the U.S. Treasury 31% of taxable dividends or gross proceeds realized upon sale
paid to shareholders who have failed to provide a correct tax identification
number in the manner required, who are subject to withholding by the Internal
Revenue Service for failure properly to include on their return payments of
taxable interest or dividends, or who have failed to certify to the Fund when
required to do so either that they are not subject to backup withholding or that
they are "exempt recipients."

Tax-Exempt Funds
----------------

          As stated in their Prospectus, the Tax-Exempt Funds are not intended
to constitute a balanced investment program and are not designed for investors
seeking capital appreciation or maximum tax-exempt income irrespective of
fluctuations in principal.  Shares of the Tax-Exempt Funds would not be suitable
for tax-exempt institutions and may not be suitable for retirement plans
qualified under Section 401 of the Code, H.R. 10 plans and individual retirement
accounts because such plans and accounts are generally tax-exempt and,
therefore, not only would not gain any additional benefit from the Tax-Exempt
Funds' dividends being tax-exempt, but such dividends would be ultimately
taxable to the beneficiaries when distributed to them.  In addition, the Tax-
Exempt Funds may not be an appropriate investment for entities which are
"substantial users" of

                                     -30-
<PAGE>
 
facilities financed by private activity bonds or "related persons" thereof.
"Substantial user" is defined under the Treasury Regulations to include a non-
exempt person who regularly uses a part of such facilities in his trade or
business and whose gross revenues derived with respect to the facilities
financed by the issuance of bonds are more than 5% of the total revenues derived
by all users of such facilities, who occupies more than 5% of the usable area of
such facilities or for whom such facilities or a part thereof were specifically
constructed, reconstructed or acquired.  "Related persons" include certain
related natural persons, affiliated corporations, a partnership and its partners
and an S Corporation and its shareholders.

          In order for a Tax-Exempt Fund to pay exempt-interest dividends for
any taxable year, at least 50% of the aggregate value of such Fund's portfolio
must consist of exempt-interest obligations at the close of each quarter of its
taxable year.  Within 60 days after the close of the taxable year, each of the
Tax-Exempt Funds will notify its shareholders of the portion of the dividends
paid by that Fund which constitutes an exempt-interest dividend with respect to
such taxable year.  However, the aggregate amount of dividends so designated by
that Fund cannot exceed the excess of the amount of interest exempt from tax
under Section 103 of the Code received by that Fund during the taxable year over
any amounts disallowed as deductions under Sections 265 and 171(a)(2) of the
Code.  The percentage of total dividends paid by each of the Tax-Exempt Funds
with respect to any taxable year which qualifies as exempt-interest dividends
will be the same for all shareholders receiving dividends from that Tax-Exempt
Fund for such year.

          A percentage of the interest on indebtedness incurred by a shareholder
to purchase or carry a Tax-Exempt Fund's Shares, equal to the percentage of the
total non-capital gain dividends distributed during the shareholder's taxable
year that is exempt - interest dividends, is not deductible for Federal income
tax purposes.  In addition, if a shareholder holds Tax-Exempt Fund Shares for
six months or less, any loss on the sale or exchange of those Shares will be
disallowed to the extent of the amount of exempt-interest dividends received
with respect to the Shares.  The Treasury Department, however, is authorized to
issue regulations reducing the six-month holding requirement to a period of not
less than the greater of 31 days or the period between regular dividend
distributions where the investment company regularly distributes at least 90% of
its net tax-exempt interest.  No such regulations had been issued as of the date
of this Statement of Additional Information.

Taxation of Certain Financial Instruments
-----------------------------------------

          Generally, futures contracts held by the Funds at the close of their
taxable year will be treated for Federal income

                                     -31-
<PAGE>
 
tax purposes as sold for their fair market value on the last business day of
such year, a process known as "marking-to-market."  Forty percent of any gain or
loss resulting from such constructive sale will be treated as short-term capital
gain or loss and 60% of such gain or loss will be treated as long-term capital
gain or loss, without regard to the length of time a Fund has held the futures
contract (the "40%-60% rule").  The amount of any capital gain or loss actually
realized by a Fund in a subsequent sale or other disposition of those futures
contracts will be adjusted to reflect any capital gain or loss taken into
account by the Fund in a prior year as a result of the constructive sale of the
contracts.  With respect to futures contracts to sell, which will be regarded as
parts of a "mixed straddle" because their values fluctuate inversely to the
values of specific securities held by a Fund, losses as to such contracts to
sell will be subject to certain loss deferral rules which limit the amount of
loss currently deductible on either part of the straddle to the amount thereof
which exceeds the unrecognized gain (if any) with respect to the other part of
the straddle, and to certain wash sales regulations.  Under short sales rules,
which also are applicable, the holding period of the securities forming part of
the straddle will (if they have not been held for the long-term holding period)
be deemed not to begin prior to termination of the straddle.  With respect to
certain futures contracts, deductions for interest and carrying charges will not
be allowed.  Notwithstanding the rules described above, with respect to futures
contracts to sell which are properly identified as such, a Fund may make an
election which will exempt (in whole or in part) those identified futures
contracts from being treated for Federal income tax purposes as sold on the last
business day of the Fund's taxable year, but gains and losses will be subject to
such short sales, wash sales and loss deferral rules, and the requirement to
capitalize interest and carrying charges.  Under temporary regulations, the Fund
would be allowed (in lieu of the foregoing) to elect either (1) to offset gains
or losses from positions which are part of a mixed straddle by separately
identifying each mixed straddle to which such treatment applies, or (2) to
establish a mixed straddle account for which gains and losses would be
recognized and offset on a periodic basis during the taxable year.  Under either
election, the 40%-60% rule will apply to the net gain or loss attributable to
the futures contracts, but in the case of a mixed straddle account election, not
more than 50 percent of any net gain may be treated as long term and no more
than 40 percent of any net loss may be treated as short term.  Options on
futures contracts generally receive Federal tax treatment similar to that
described above.

          A Fund will not be treated as a regulated investment company under the
Code if 30% or more of the Fund's gross income for a taxable year is derived
from gains realized on the sale or other disposition of the following
investments held for less than

                                     -32-
<PAGE>
 
three months (the "30% test"):  (1) stock and securities (as defined in section
2(a)(36) of the 1940 Act); (2) options, futures and forward contracts other than
those on foreign currencies; and (3) foreign currencies (and options, futures
and forward contracts on foreign currencies) that are not directly related to
the Fund's principal business of investing in stock and securities (and options
and futures with respect to stocks and securities).  Interest (including
original issue discount and accrued market discount) received by the Fund upon
maturity or disposition of a security held for less than three months will not
be treated as gross income derived from the sale or other disposition of such
security within the meaning of this requirement.  However, any other income
which is attributable to realized market appreciation will be treated as gross
income from the sale or other disposition of securities for this purpose.  With
respect to forward contracts, futures contracts, options on futures contracts,
and other financial instruments subject to the marking-to-market rules described
above, the Internal Revenue Service has ruled in private letter rulings that a
gain realized from such a contract, option or financial instrument will be
treated as being derived from a security held for three months or more
(regardless of the actual period for which the contract, option or instrument is
held) if the gain arises as a result of a constructive sale under the marking-
to-market rules, and will be treated as being derived from a security held for
less than three months only if the contract, option or instrument is terminated
(or transferred) during the taxable year (other than by reason of marking-to-
market) and less than three months have elapsed between the date the contract,
option or instrument is acquired and the termination date.  Increases and
decreases in the value of a Fund's futures contracts and other investments that
qualify as part of a "designated hedge," as defined in Section 851(g) of the
Code, may be netted for purposes of determining whether the 30% test is met.

                              *        *        *

          The foregoing discussion is based on Federal tax laws and regulations
which are in effect on the date of this Statement of Additional Information;
such laws and regulations may be changed by legislative or administrative
action.  Shareholders are advised to consult their tax advisers concerning their
specific situations and the application of state and local taxes.

                       PERFORMANCE AND YIELD INFORMATION
                       ---------------------------------

Yields and Performance
----------------------

          The Funds may advertise the standardized effective 30-day (or one
month) yields calculated in accordance with the method prescribed by the
Securities and Exchange Commission for

                                     -33-
<PAGE>
 
mutual funds.  Such yield will be calculated separately for each Fund according
to the following formula:

                             a-b
               Yield = 2 [(-------- + 1)/6/ - 1]
                              cd

          Where:    a =  dividends and interest earned during the period.

                    b =  expenses accrued for the period (net of
                         reimbursements).

                    c =  average daily number of Shares outstanding that were
                         entitled to receive dividends.

                    d =  maximum offering price per Share on the last day of the
                         period.

          For the purpose of determining interest earned during the period
(variable "a" in the formula), each of the Funds computes the yield to maturity
of any debt obligation held by it based on the market value of the obligation
(including actual accrued interest) at the close of business on the last
business day of each month, or, with respect to obligations purchased during the
month, the purchase price (plus actual accrued interest).  Such yield is then
divided by 360, and the quotient is multiplied by the market value of the
obligation (including actual accrued interest) in order to determine the
interest income on the obligation for each day of the subsequent month that the
obligation is in the portfolio.  It is assumed in the above calculation that
each month contains 30 days.  Also, the maturity of a debt obligation with a
call provision is deemed to be the next call date on which the obligation
reasonably may be expected to be called or, if none, the maturity date.  Each of
the Funds calculates interest gained on tax-exempt obligations issued without
original issue discount and having a current market discount by using the coupon
rate of interest instead of the yield to maturity.  In the case of tax-exempt
obligations with original issue discount, where the discount based on the
current market value exceeds the then-remaining portion of original issue
discount, the yield to maturity is the imputed rate based on the original issue
discount calculation.  Conversely, where the discount based on the current
market value is less than the remaining portion of the original issue discount,
the yield to maturity is based on the market value.

          Expenses accrued for the period (variable "b" in the formula) include
all recurring fees charged by each of the Funds to all shareholder accounts and
to the particular series of

                                     -34-
<PAGE>
 
Shares in proportion to the length of the base period and that Fund's mean (or
median) account size.  Undeclared earned income will be subtracted from the
maximum offering price per Share (variable "d" in the formula).  The Funds'
maximum offering price per Share for purposes of the formula will include the
maximum sales load imposed by the Funds -- currently 4.50% of the per share
offering price.  Based on the foregoing calculations, the effective yields for
Shares of the IT Tax-Exempt, LT Tax-Exempt, Managed Income, Short-Term Tax-
Exempt, IT Income and ST Government Funds for the 30-day period ended March 31,
1995 were 4.43%, 5.48%, 6.44%, 3.95%, 6.38% and 5.88%, respectively.

          The "tax-equivalent" yield of the Short-Term Tax-Exempt, IT Tax-Exempt
and LT Tax-Exempt Funds is computed by:  (a) dividing the portion of the yield
(calculated as above) that is exempt from Federal income tax by one minus a
stated Federal income tax rate and (b) adding that figure to that portion, if
any, of the yield that is not exempt from Federal income tax.  Tax-equivalent
yields assume the payment of Federal income taxes at a rate of 31%.  Based on
the foregoing calculations, the tax-equivalent yield of the Short-Term Tax-
Exempt, IT Tax-Exempt and LT Tax-Exempt Funds for the 30-day period ended March
31, 1995 were 5.72%, 6.42% and 7.94%, respectively.

          Each Fund's "average annual total return" is computed by determining
the average annual compounded rate of return during specified periods that
equates the initial amount invested to the ending redeemable value of such
investment according to the following formula:

                           ERV  /1/n/
                    T = [(-----) - 1]
                            P

               Where:    T =  average annual total return.

                       ERV =  ending redeemable value of a hypothetical $1,000
                              payment made at the beginning of the 1, 5 or 10
                              year (or other) periods at the end of the
                              applicable period (or a fractional portion
                              thereof).

                         P =  hypothetical initial payment of $1,000.

                         n =  period covered by the computation, expressed in
                              years.

     Each Fund that advertises an "aggregate total return" computes such return
by determining the aggregate compounded

                                     -35-
<PAGE>
 
rates of return during specified periods that likewise equate the initial amount
invested to the ending redeemable value of such investment.  The formula for
calculating aggregate total return is as follows:

                                         ERV
             Aggregate Total Return = [(------)] - 1
                                          P
 

          The above calculations are made assuming that (1) all dividends and
capital gain distributions are reinvested on the reinvestment dates at the price
per Share existing on the reinvestment date (reflecting any sales load charged
upon such reinvestment), (2) all recurring fees charged to all shareholder
accounts are included, and (3) for any account fees that vary with the size of
the account, a mean (or median) account size in the Fund during the periods is
reflected.  The ending redeemable value (variable "ERV', in the formula) is
determined by assuming complete redemption of the hypothetical investment after
deduction of all nonrecurring charges at the end of the measuring period.  In
addition, the Funds' average annual total return and aggregate total return
quotations will reflect the deduction of the maximum sales load charged in
connection with the purchase of Shares.

          Based on the foregoing calculations, the average annual total returns
for Shares of the Short-Term Tax-Exempt Fund, IT Tax-Exempt Fund, LT Tax-Exempt
Fund, ST Government Fund, IT Income Fund and Managed Income Fund for the one
year period ended March 31, 1995 were (1.21)%, 1.52%, 5.99%, (0.44)%, 0.26% and
(0.58)%, respectively.  The average annual total returns for the IT Tax-Exempt
Fund, LT Tax-Exempt Fund and Managed Income Fund for the five year period ended
March 31, 1995 were 6.40%, 8.69% and 7.91%, respectively.  The average annual
total returns for the IT Tax-Exempt, LT Tax-Exempt and Managed Income Funds for
the periods from their commencement of operations (December 3, 1985, February 5,
1986, and January 9, 1986, respectively) to March 31, 1995 were 7.69%, 10.67%
and 10.10%, respectively.  The average annual total returns for the Short-Term
Tax-Exempt, IT Income and ST Government Funds for the period from their
commencement of operations (December 31, 1992) to March 31, 1995 were 1.32%,
2.00% and 1.51%, respectively.

          The Funds may also from time to time include in advertisements, sales
literature and communications to shareholders a total return figure that is not
calculated according to the formula set forth above in order to compare more
accurately a Fund's performance with other measures of investment return.  For
example, in comparing a Fund's total return with data published by Lipper
Analytical Services, Inc., CDA Investment Technologies, Inc. or Weisenberger
Investment Company

                                     -36-
<PAGE>
 
Service, or with the performance of an index, a Fund may calculate its aggregate
total return for the period of time specified in the advertisement, sales
literature or communication by assuming the investment of $10,000 in Shares and
assuming the reinvestment of each dividend or other distribution at net asset
value on the reinvestment date.  Percentage increases are determined by
subtracting the initial value of the investment from the ending value and by
dividing the remainder by the beginning value.  A Fund does not, for these
purposes, deduct from the initial value invested any amount representing sales
charges.  A Fund will, however, disclose the maximum sales charge and will also
disclose that the performance data does not reflect sales charges and that
inclusion of sale charges would reduce the performance quoted.

          The total return and yield of a Fund may be compared to those of other
mutual funds with similar investment objectives and to other relevant indices or
to ratings prepared by independent services or other financial or industry
publications that monitor the performance of mutual funds.  For example, the
total return and/or yield of a Fund may be compared to data prepared by Lipper
Analytical Services, Inc., CDA Investment Technologies, Inc. and Weisenberger
Investment Company Service.  Total return and yield data as reported in national
financial publications such as Money Magazine, Forbes, Barron's, The Wall Street
                               ----- --------  ------  --------  --- ---- ------
Journal and The New York Times, or in publications of a local or regional
-------     --- --- ---- -----                                           
nature, may also be used in comparing the performance of a Fund.
Advertisements, sales literature or reports to shareholders may from time to
time also include a discussion and analysis of each Fund's performance,
including without limitation, those factors, strategies and technologies that
together with market conditions and events, materially affected each Fund's
performance.

          The Funds may also from time to time include discussions or
illustrations of the effects of compounding in advertisements. "Compounding"
refers to the fact that, if dividends or other distributions of a Fund
investment are reinvested by being paid in additional Fund shares, any future
income or capital appreciations of a Fund would increase the value, not only of
the original Fund investment, but also of the additional Fund shares received
through reinvestment. As a result, the value of the Fund investment would
increase more quickly than if dividends or other distributions had been paid in
cash. The Funds may also include discussions or illustrations of the potential
investment goals of a prospective investor, investment management techniques,
policies or investment suitability of a Fund, economic conditions, the effects
of inflation and historical performance of various asset classes, including but
not limited to, stocks, bonds and Treasury bills. From time to time
advertisements, sales literature or communications to shareholders may summarize
the substance of information contained

                                     -37-
<PAGE>
 
in shareholder reports (including the investment composition of a Fund), as well
as the views of the Investment Adviser as to current market, economy, trade and
interest rate trends, legislative, regulatory and monetary developments,
investment strategies and related matters believed to be of relevance to a Fund.
The Funds may also include in advertisements charts, graphs or drawings which
illustrate the potential risks and rewards of investment in various investment
vehicles, including but not limited to, stocks, bonds, treasury bills and shares
of a Fund.  In addition, advertisement, sales literature or shareholder
communications may include a discussion of certain attributes or benefits to be
derived by an investment in a Fund.  Such advertisements or communicators may
include symbols, headlines or other material which highlight or summarize the
information discussed in more detail therein.


                                 MISCELLANEOUS
                                 -------------

          As used in the Prospectus, "assets belonging to a Fund" means the
consideration received upon the issuance of Shares in the Fund, together with
all income, earnings, profits, and proceeds derived from the investment thereof,
including any proceeds from the sale of such investments, any funds or payments
derived from any reinvestment of such proceeds, and a portion of any general
assets of the Company involved not belonging to a particular portfolio of that
Company.  In determining the net asset value of a Fund's Shares, assets
belonging to the Fund are charged with the direct liabilities in respect of that
Fund and with a share of the general liabilities of the Company involved which
are normally allocated in proportion to the relative asset values of the
Company's portfolios at the time of allocation.  Subject to the provisions of
the Companies' Charters, determinations by the Boards of Directors as to the
direct and allocable liabilities and the allocable portion of any general assets
with respect to a particular Fund are conclusive.

          As of July 11, 1995 U.S. Trust held of record substantially all of the
outstanding Shares in all Funds other than the Managed Income Fund, where it
held a majority of the Shares, acting as agent or custodian for its customers,
but did not own such Shares beneficially because it did not have discretion to
vote or invest such Shares.

          As of July 11, 1995, the name, address and percentage ownership of
each person, in addition to U.S. Trust, that beneficially owned 5% or more of
the outstanding Shares of the Short-Term Tax-Exempt Fund was as follows:  G.L. &
J.E. Swenson, c/o United States Trust Company of New York, 114 West 47th Street,
New York, New York 10036, 7.2%.

                                   ----------


Commercial Paper Ratings
------------------------

          A Standard & Poor's commercial paper rating is a current assessment of
the likelihood of timely payment of debt considered short-term in the relevant
market.  The following summarizes the rating categories used by Standard and
Poor's for commercial paper:

          "A-1" - Issue's degree of safety regarding timely payment is strong.
Those issues determined to possess extremely strong safety characteristics are
denoted "A-1+."

          "A-2" - Issue's capacity for timely payment is satisfactory.  However,
the relative degree of safety is not as high as for issues designated "A-1."

          "A-3" - Issue has an adequate capacity for timely payment.  It is,
however, somewhat more vulnerable to the adverse effects of changes and
circumstances than an obligation carrying a higher designation.

          "B" - Issue has only a speculative capacity for timely payment.

          "C" - Issue has a doubtful capacity for payment.

          "D" - Issue is in payment default.


          Moody's commercial paper ratings are opinions of the ability of
issuers to repay punctually promissory obligations not having an original
maturity in excess of 9 months.  The following summarizes the rating categories
used by Moody's for commercial paper:

          "Prime-1" - Issuer or related supporting institutions are considered
to have a superior capacity for repayment of short-term promissory obligations.
Prime-1 repayment capacity will normally be evidenced by the following
characteristics: leading market positions in well established industries; high
rates of return on funds employed; conservative capitalization structures with
moderate reliance on debt and ample asset protection; broad margins in earning
coverage of fixed financial charges and high internal cash generation; and well
established access to a range of financial markets and assured sources of
alternate liquidity.

                                      A-1
<PAGE>
 
          "Prime-2" - Issuer 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 cited above 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.

          "Prime-3" - Issuer or related supporting institutions have an
acceptable capacity for repayment of short-term promissory obligations.  The
effects of industry characteristics and market composition may be more
pronounced.  Variability in earnings and profitability may result in changes in
the level of debt protection measurements and the requirement for relatively
high financial leverage.  Adequate alternate liquidity is maintained.

          "Not Prime" - Issuer does not fall within any of the Prime rating
categories.


          The three rating categories of Duff & Phelps for investment grade
commercial paper and short-term debt are "D-1," "D-2" and "D-3."  Duff & Phelps
employs three designations, "D-1+," "D-1" and "D-1-," within the highest rating
category.  The following summarizes the rating categories used by Duff & Phelps
for commercial paper:

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

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

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

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

          "D-3" - Debt possesses satisfactory liquidity, and other protection
factors qualify issue as investment grade.  Risk

                                      A-2
<PAGE>
 
factors are larger and subject to more variation.  Nevertheless, timely payment
is expected.

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

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


          Fitch short-term ratings apply to debt obligations that are payable on
demand or have original maturities of up to three years.  The following
summarizes the rating categories used by Fitch for short-term obligations:

          "F-1+" - Securities possess exceptionally strong credit quality.
Issues assigned this rating are regarded as having the strongest degree of
assurance for timely payment.

          "F-1" - Securities possess very strong credit quality.  Issues
assigned this rating reflect an assurance of timely payment only slightly less
in degree than issues rated "F-1+."

          "F-2" - Securities possess good credit quality.  Issues assigned this
rating have a satisfactory degree of assurance for timely payment, but the
margin of safety is not as great as the "F-1+" and "F-1" categories.

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

          "F-S" - Securities possess weak credit quality.  Issues assigned this
rating have characteristics suggesting a minimal degree of assurance for timely
payment and are vulnerable to near-term adverse changes in financial and
economic conditions.

          "D" - Securities are in actual or imminent payment default.

          Fitch may also use the symbol "LOC" with its short-term ratings to
indicate that the rating is based upon a letter of credit issued by a commercial
bank.


          Thomson BankWatch short-term ratings assess the likelihood of an
untimely or incomplete payment of principal or

                                      A-3
<PAGE>
 
interest of unsubordinated instruments having a maturity of one year or less
which is issued by United States commercial banks, thrifts and non-bank banks;
non-United States banks; and broker-dealers.  The following summarizes the
ratings used by Thomson BankWatch:

          "TBW-1" - This designation represents Thomson BankWatch's highest
rating category and indicates a very high degree of likelihood that principal
and interest will be paid on a timely basis.

          "TBW-2" - This designation indicates that while the degree of safety
regarding timely payment of principal and interest is strong, the relative
degree of safety is not as high as for issues rated "TBW-1."

          "TBW-3" - This designation represents the lowest investment grade
category and indicates that while the debt is more susceptible to adverse
developments (both internal and external) than obligations with higher ratings,
capacity to service principal and interest in a timely fashion is considered
adequate.

          "TBW-4" - This designation indicates that the debt is regarded as non-
investment grade and therefore speculative.


          IBCA assesses the investment quality of unsecured debt with an
original maturity of less than one year which is issued by bank holding
companies and their principal bank subsidiaries.  The following summarizes the
rating categories used by IBCA for short-term debt ratings:

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

          "A2" - Obligations are supported by a good capacity for timely
repayment.

          "A3" - Obligations are supported by a satisfactory capacity for timely
repayment.

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

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

                                      A-4

Corporate and Municipal Long-Term Debt Ratings
----------------------------------------------

          The following summarizes the ratings used by Standard & Poor's for
corporate and municipal debt:

          "AAA" - This designation represents the highest rating assigned by
Standard & Poor's to a debt obligation and indicates an extremely strong
capacity to pay interest and repay principal.

          "AA" - Debt is considered to have a very strong capacity to pay
interest and repay principal and differs from AAA issues only in small degree.

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

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

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

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

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

                                      A-5
<PAGE>
 
          "CCC" - Debt has a currently identifiable vulnerability to default,
and is dependent upon favorable business, financial and economic conditions to
meet timely payment of interest and repayment of principal.  In the event of
adverse business, financial or economic conditions, it is not likely to have the
capacity to pay interest and repay principal.  The "CCC" rating category is also
used for debt subordinated to senior debt that is assigned an actual or implied
"B" or "B-" rating.

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

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

          "CI" - This rating is reserved for income bonds on which no interest
is being paid.

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

          PLUS (+) OR MINUS (-) - The ratings from "AA" through "CCC" may be
modified by the addition of a plus or minus sign to show relative standing
within the major rating categories.

          "r" - This rating is attached to highlight derivative, hybrid, and
certain other obligations that S & P believes may experience high volatility or
high variability in expected returns due to non-credit risks.  Examples of such
obligations are: securities whose principal or interest return is indexed to
equities, commodities, or currencies; certain swaps and options; and interest
only and principal only mortgage securities.

     The following summarizes the ratings used by Moody's for corporate and
municipal long-term debt:

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

                                      A-6
<PAGE>
 
unlikely to impair the fundamentally strong position of such issues.

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

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

          "Baa" - Bonds considered medium-grade obligations, i.e., they are
neither highly protected nor poorly secured.  Interest payments and principal
security appear adequate for the present but certain protective elements may be
lacking or may be characteristically unreliable over any great length of time.
Such bonds lack outstanding investment characteristics and in fact have
speculative characteristics as well.

          "Ba," "B," "Caa," "Ca," and "C" - Bonds that possess one of these
ratings provide questionable protection of interest and principal ("Ba"
indicates some speculative elements; "B" indicates a general lack of
characteristics of desirable investment; "Caa" represents a poor standing; "Ca"
represents obligations which are speculative in a high degree; and "C"
represents the lowest rated class of bonds). "Caa," "Ca" and "C" bonds may be in
default.

          Con. (---) - Bonds for which the security depends upon the completion
of some act or the fulfillment of some condition are rated conditionally.  These
are bonds secured by (a) earnings of projects under construction, (b) earnings
of projects unseasoned in operation experience, (c) rentals which begin when
facilities are completed, or (d) payments to which some other limiting condition
attaches.  Parenthetical rating denotes probable credit stature upon completion
of construction or elimination of basis of condition.

          Moody's applies numerical modifiers 1, 2 and 3 in each generic
classification from "Aa" to "B" in its bond rating system.  The modifier 1
indicates that the issuer 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 issuer ranks at the lower end of its generic rating category.

                                      A-7
<PAGE>
 
          The following summarizes the long-term debt ratings used by Duff &
Phelps for corporate and municipal long-term debt:

          "AAA" - Debt is considered to be of the highest credit quality.  The
risk factors are negligible, being only slightly more than for risk-free U.S.
Treasury debt.

          "AA" - Debt is considered of high credit quality.  Protection factors
are strong.  Risk is modest but may vary slightly from time to time because of
economic conditions.

          "A" - Debt possesses protection factors which are average but
adequate.  However, risk factors are more variable and greater in periods of
economic stress.

          "BBB" - Debt possesses below average protection factors but such
protection factors are still considered sufficient for prudent investment.
Considerable variability in risk is present during economic cycles.

          "BB," "B," "CCC," "DD," and "DP" - Debt that possesses one of these
ratings is considered to be below investment grade.  Although below investment
grade, debt rated "BB" is deemed likely to meet obligations when due.  Debt
rated "B" possesses the risk that obligations will not be met when due.  Debt
rated "CCC" is well below investment grade and has considerable uncertainty as
to timely payment of principal, interest or preferred dividends.  Debt rated
"DD" is a defaulted debt obligation, and the rating "DP" represents preferred
stock with dividend arrearages.

          To provide more detailed indications of credit quality, the "AA," "A,"
"BBB," "BB" and "B" ratings may be modified by the addition of a plus (+) or
minus (-) sign to show relative standing within these major categories.


          The following summarizes the highest four ratings used by Fitch for
corporate and municipal bonds:

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

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

                                      A-8
<PAGE>
 
          "A" - Bonds considered to be investment grade and of high credit
quality.  The obligor's ability to pay interest and repay principal is
considered to be strong, but may be more vulnerable to adverse changes in
economic conditions and circumstances than bonds with higher ratings.

          "BBB" - Bonds considered to be investment grade and of satisfactory
credit quality.  The obligor's ability to pay interest and repay principal is
considered to be adequate.  Adverse changes in economic conditions and
circumstances, however, are more likely to have an adverse impact on these
bonds, and therefore, impair timely payment.  The likelihood that the ratings of
these bonds will fall below investment grade is higher than for bonds with
higher ratings.

          "BB," "B," "CCC," "CC," "C," "DDD," "DD," and "D" -Bonds that possess
one of these ratings are considered by Fitch to be speculative investments.  The
ratings "BB" to "C" represent Fitch's assessment of the likelihood of timely
payment of principal and interest in accordance with the terms of obligation for
bond issues not in default.  For defaulted bonds, the rating "DDD" to "D" is an
assessment of the ultimate recovery value through reorganization or liquidation.

          To provide more detailed indications of credit quality, the Fitch
ratings from and including "AA" to "C" may be modified by the addition of a plus
(+) or minus (-) sign to show relative standing within these major rating
categories.


          IBCA assesses the investment quality of unsecured debt with an
original maturity of more than one year which is issued by bank holding
companies and their principal bank subsidiaries.  The following summarizes the
rating categories used by IBCA for long-term debt ratings:

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

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

          "A" - Obligations for which there is a low expectation of investment
risk.  Capacity for timely repayment of principal and interest is strong,
although adverse changes in business,

                                      A-9
<PAGE>
 
economic or financial conditions may lead to increased investment risk.

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

          "BB," "B," "CCC," "CC," and "C" - Obligations are assigned one of
these ratings where it is considered that speculative characteristics are
present.  "BB" represents the lowest degree of speculation and indicates a
possibility of investment risk developing.  "C" represents the highest degree of
speculation and indicates that the obligations are currently in default.

          IBCA may append a rating of plus (+) or minus (-) to a rating to
denote relative status within major rating categories.


          Thomson BankWatch assesses the likelihood of an untimely repayment of
principal or interest over the term to maturity of long term debt and preferred
stock which are issued by United States commercial banks, thrifts and non-bank
banks; non-United States banks; and broker-dealers.  The following summarizes
the rating categories used by Thomson BankWatch for long-term debt ratings:

          "AAA" - This designation represents the highest category assigned by
Thomson BankWatch to long-term debt and indicates that the ability to repay
principal and interest on a timely basis is very high.

          "AA" - This designation indicates a superior ability to repay
principal and interest on a timely basis with limited incremental risk versus
issues rated in the highest category.

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

          "BBB" - This designation represents Thomson BankWatch's lowest
investment grade category and indicates an acceptable capacity to repay
principal and interest.  Issues rated "BBB" are, however, more vulnerable to
adverse developments (both internal and external) than obligations with higher
ratings.

                       INVESTMENT OBJECTIVE AND POLICIES
                       ---------------------------------

          The investment objective of the Fund is to provide New York investors
with as high a level of current interest income exempt from Federal income tax,
and, to the extent possible, from New York state and New York City personal
income taxes, as is consistent with relative stability of principal.  Under
normal market conditions, at least 80% of the Fund's assets will be invested in
Municipal Obligations (as defined in the Prospectus), and at least 65% of the
Fund's assets will be invested in New York Municipal Obligations (as defined in
the Prospectus).  The following policies supplement the Fund's investment
objective and policies as set forth in the Prospectus.


Additional Information on Portfolio Instruments
-----------------------------------------------

          Municipal Obligations
          ---------------------

          Municipal Obligations include debt obligations issued by governmental
entities to obtain funds for various public purposes, including the construction
of a wide range of public facilities, the refunding of outstanding obligations,
the payment of general operating expenses, and the extension of loans to public
institutions and facilities.  Private activity bonds that are issued by or on
behalf of public authorities to finance various privately operated facilities
are included within the term "Municipal Obligations" only if the interest paid
thereon is exempt from general Federal income tax and not treated as a specific
tax preference item under the Federal alternative minimum tax.

          The two principal classifications of Municipal Obligations are
"general obligation" and "revenue" issues, but the Fund's portfolio may also
include "moral obligation" issues, which are normally issued by special-purpose
authorities.  There are, of course, variations in the quality of Municipal
Obligations, both within a particular classification and between
classifications, and the yields on Municipal Obligations 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 Moody's Investors Service, Inc. ("Moody's") and Standard
& Poor's Ratings Group ("S&P") described in the Prospectus and Appendix A hereto
represent their opinion as to the quality of Municipal Obligations.  It should
be emphasized that these ratings are general and are not absolute standards of
quality, and Municipal Obligations with the same maturity, interest rate, and
rating may have different yields while Municipal Obligations of the same
maturity and interest rate with different ratings may have the same yield.
Subsequent

                                      -1-
<PAGE>
 
to its purchase by the Fund, an issue of Municipal Obligations may cease to be
rated, or its rating may be reduced below the minimum rating required for
purchase by the Fund.  United States Trust Company of New York, the Fund's
investment adviser ("U.S. Trust" or the "Investment Adviser"), will consider
such an event in determining whether the Fund should continue to hold the
obligation.

          The payment of principal and interest on most securities purchased by
the Fund will depend upon the ability of the issuers to meet their obligations.
Each state, the District of Columbia, each of their political subdivisions,
agencies, instrumentalities and authorities, and each multistate agency of which
a state is a member, is a separate "issuer" as that term is used in this
Statement of Additional Information and the Fund's Prospectus.  The non-
governmental user of facilities financed by private activity bonds is also
considered to be an "issuer."  An issuer's obligations under its Municipal
Obligations 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.  The power or ability of an issuer to
meet its obligations for the payment of interest on and principal of its
Municipal Obligations may be materially adversely affected by litigation or
other conditions.

          Private activity bonds are issued to obtain funds to provide, among
other things, privately operated housing facilities, pollution control
facilities, convention or trade show facilities, mass transit, airport, port or
parking facilities and certain local facilities for water supply, gas,
electricity or sewage or solid waste disposal.  Private activity bonds are also
issued to privately held or publicly owned corporations in the financing of
commercial or industrial facilities.  State and local governments are authorized
in most states to issue private activity bonds for such purposes in order to
encourage corporations to locate within their communities.  The principal and
interest on these obligations may be payable from the general revenues of the
users of such facilities.

          From time to time, proposals have been introduced before Congress for
the purpose of restricting or eliminating the Federal income tax exemption for
interest on Municipal Obligations.  For example, under the Tax Reform Act of
1986, as amended, interest on certain private activity bonds must be included in
an investor's alternative minimum taxable income, and corporate investors must
treat all tax-exempt interest as an item of tax preference.  Master Tax-Exempt
Fund cannot, of course, predict what legislation may be proposed in the future
regarding

                                      -2-
<PAGE>
 
the income tax status of interest on Municipal Obligations, or which proposals,
if any, might be enacted.  Such proposals, while pending or if enacted, might
materially adversely affect the availability of Municipal Obligations for
investment by the Fund and the liquidity and value of its portfolio.  In such an
event, the Fund would reevaluate its investment objective and policies and
consider possible changes in its structure or possible dissolution.

          Opinions relating to the validity of Municipal Obligations and to the
exemption of interest thereon from Federal income tax are rendered by bond
counsel to the respective issuers at the time of issuance.  Neither the Fund nor
its Investment Adviser will review the proceedings relating to the issuance of
Municipal Obligations or the basis for such opinions.

          Money Market Instruments
          ------------------------

          Certificates of deposit acquired by the Fund within the limits set
forth in the Prospectus will be those of (i) domestic branches of U.S. banks
which are members of the Federal Reserve System or are insured by the Bank
Insurance Fund of the Federal Deposit Insurance Corporation ("FDIC"), or (ii)
savings and loan associations which are insured by the Savings Association
Insurance Fund of the FDIC. (The foregoing limitation does not preclude the Fund
from acquiring Municipal Obligations which are backed by letters of credit
issued by foreign banks.)

          Tax-exempt commercial paper purchased by the Fund will consist of
issues rated at the time of purchase "A-2" or higher by S&P or "Prime-2" or
better by Moody's or, if not rated, determined to be of comparable quality by
the Investment Adviser.  These rating symbols are described in Appendix A
hereto.

          Insured Municipal Obligations
          -----------------------------

          The Fund may purchase Municipal Obligations which are insured as to
timely payment of principal and interest at the time of purchase.  The insurance
policies will usually be obtained by the issuer of the bond at the time of its
original issuance. Bonds of this type will be acquired only if at the time of
purchase they satisfy quality requirements generally applicable to Municipal
Obligations as described in the Prospectus. Although insurance coverage for the
Municipal Obligations held by the Fund reduces credit risk by insuring that the
Fund will receive timely payment of principal and interest, it does not protect
against market fluctuations caused by changes in interest rates and other
factors. The Fund may invest more than 25% of its net assets in Municipal
Obligations covered by insurance policies.

                                      -3-
<PAGE>
 
          Repurchase Agreements
          ---------------------

          The repurchase price under the repurchase agreements described in the
Prospectus generally equals the price paid by the Fund plus interest negotiated
on the basis of current short-term rates (which may be more or less than the
rate on securities underlying the repurchase agreement). Securities subject to
repurchase agreements are held by the Fund's custodian (or sub-custodian) or in
the Federal Reserve/Treasury book-entry system. Repurchase agreements are
considered loans by the Fund under the Investment Company Act of 1940 (the "1940
Act").

          When-Issued and Forward Transactions
          ------------------------------------

          When the Fund agrees to purchase securities on a "when-issued" or
forward commitment basis, the custodian will set aside cash or liquid portfolio
securities equal to the amount of the commitment in a separate account.
Normally, the custodian will set aside portfolio securities to satisfy a
purchase commitment, and, in such case, the Fund may be required subsequently to
place additional assets in the separate 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 or 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
forward commitments or commitments to purchase "when-issued" securities ever
exceeded 25% of the value of its assets.

          The Fund will purchase securities on a "when-issued" or forward
commitment basis only with the intention of completing the transaction.  If
deemed advisable as a matter of investment strategy, however, the Fund may
dispose of or renegotiate a commitment after it is entered into, and may sell
securities it has committed to purchase before those securities are delivered to
the Fund on the settlement date.  In these cases, the Fund may realize a taxable
capital gain or loss.

          When the Fund engages in "when-issued" or forward commitment
transactions, it relies on the other party to consummate the trade.  Failure of
such other party to do so may result in the Fund incurring a loss or missing an
opportunity to obtain a price considered to be advantageous.

          The market value of the securities underlying a "when-issued" purchase
or a forward commitment to purchase securities and any subsequent fluctuations
in their market value are taken into account when determining the market value
of the Fund starting on the day the Fund agrees to purchase the securities.

                                      -4-
<PAGE>
 
The Fund does not earn interest on the securities it has committed to purchase
until they are paid for and delivered on the settlement date.

          Stand-By Commitments
          --------------------

          The Fund may acquire "stand-by commitments" with respect to Municipal
Obligations held by it.  Under a "stand-by commitment," a dealer or bank agrees
to purchase from the Fund, at the Fund's option, specified Municipal Obligations
at a specified price.  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 Obligations (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.  "Stand-by commitments" are
exercisable by the Fund at any time before the maturity of the underlying
Municipal Obligations, and may be sold, transferred or assigned by the Fund only
with the underlying instruments.

          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 securities which are acquired
subject to the commitment (thus reducing the yield to maturity otherwise
available for the same securities).  Where the Fund has paid any consideration
directly or indirectly for a "stand-by commitment," its cost will be reflected
as unrealized depreciation for the period during which the commitment was held
by the Fund.

          The Fund intends to enter into "stand-by commitments" only with banks
and broker/dealers which, in the Investment Adviser's opinion, present minimal
credit risks.  In evaluating the creditworthiness of the issuer of a "stand-by
commitment," the Investment Adviser will review periodically the issuer's
assets, liabilities, contingent claims and other relevant financial information.

          Futures Contracts
          -----------------

          The Fund may invest in interest rate futures contracts and municipal
bond index futures contracts.  Futures contracts will not be entered into for
speculative purposes, but to hedge risks associated with the Fund's securities
investments.  Positions in futures contracts may be closed out only on an
exchange which provides a secondary market for such futures.  However, there can
be no assurance that a liquid secondary market

                                      -5-
<PAGE>
 
will exist for any particular futures contract at any specific time.  Thus, it
may not be possible to close a futures position.  In the event of adverse price
movements, the Fund would continue to be required to make daily cash payments to
maintain its required margin.  In such situations, if the Fund has insufficient
cash, it may have to sell portfolio securities to meet daily margin requirements
at a time when it may be disadvantageous to do so.  In addition, the Fund may be
required to make delivery of the instruments underlying futures contracts it
holds.  The inability to close options and futures positions also could have an
adverse impact on the Fund's ability to effectively hedge.

          Successful use of futures by the Fund is also subject to the
Investment Adviser's ability to correctly predict movements in the direction of
the market.  For example, if the Fund has hedged against the possibility of a
decline in the market adversely affecting securities held by it and securities
prices increase instead, the Fund will lose part or all of the benefit to the
increased value of its securities which it has hedged because it will
approximately equal offsetting losses in its futures positions.  In addition, in
some situations, if the Fund has insufficient cash, it may have to sell
securities to meet daily variation margin requirements.  Such sale of securities
may be, but will not necessarily be, at increased prices which reflect the
rising market.  The Fund may have to sell securities at a time when it may be
disadvantageous to do so.

          The risk of loss in trading futures contracts in some strategies can
be substantial, due both to the low margin deposits required, and the extremely
high degree of leverage involved in futures pricing.  As a result, a relatively
small price movement in a futures contract may result in immediate and
substantial loss (as well as gain) to the investor.  For example, if at the time
of purchase, 10% of the value of the futures contract is deposited as margin, a
subsequent 10% decrease in the value of the futures contract would result in a
total loss of the margin deposit, before any deduction for the transaction
costs, if the account were then closed out.  A 15% decrease would result in a
loss equal to 150% of the original margin deposit, before any deduction for the
transaction costs, if the contract were closed out.  Thus, a purchase or sale of
a futures contract may result in losses in excess of the amount invested in the
contract.

          Utilization of futures transactions by the Fund involves the risk of
loss by the Fund of margin deposits in the event of bankruptcy of a broker with
whom the Fund has an open position in a futures contract or related option.

                                      -6-
<PAGE>
 
          Most futures exchanges limit the amount of fluctuation permitted in
futures contract prices during a single trading day.  The daily limit
establishes the maximum amount that the price of a futures contract may vary
either up or down from the previous day's settlement price at the end of a
trading session.  Once the daily limit has been reached in a particular type of
contract, no trades may be made on that day at a price beyond that limit.  The
daily limit governs only price movement during a particular trading day and
therefore does not limit potential losses, because the limit may prevent the
liquidation of unfavorable positions.  Futures contract prices have occasionally
moved to the daily limit for several consecutive trading days with little or no
trading, thereby preventing prompt liquidation of futures positions and
subjecting some futures traders to substantial losses.

          The trading of futures contracts is also subject to the risk of
trading halts, suspensions, exchange or clearing house equipment failures,
government intervention, insolvency of a brokerage firm or clearing house or
other disruptions of normal trading activity, which could at times make it
difficult or impossible to liquidate existing positions or to recover excess
variation margin payments.

          Miscellaneous
          -------------

          The Fund may not invest in oil, gas, or mineral leases.

Risk Factors Relating to New York Municipal Obligations
-------------------------------------------------------

          Some of the significant financial considerations relating to the
Fund's investment in New York Municipal Obligations are summarized below.  This
summary information is not intended to be a complete description and is
principally derived from official statements relating to issues of New York
Municipal Obligations that were available prior to the date of this Statement of
Additional Information.  The accuracy and completeness of the information
contained in those official statements have not been independently verified.

State Economy.  New York is the third most populous state in the nation and has
-------------                                                                  
a relatively high level of personal wealth.  The State's economy is diverse with
a comparatively large share of the nation's finance, insurance, transportation,
communications and services employment, and a very small share of the nation's
farming and mining activity.  The State has a declining proportion of its
workforce engaged in manufacturing, and an increasing proportion engaged in
service industries.  New York City (the "City"), which is the most populous city
in the State and nation and is the center of the nation's largest metropolitan
area, accounts for a large portion of the State's population and personal
income.

                                      -7-
<PAGE>
 
          The State has historically been one of the wealthiest states in the
nation.  For decades, however, the State has grown more slowly than the nation
as a whole, gradually eroding its relative economic position.  The recession has
been more severe in the State, owing to a significant retrenchment in the
financial services industry, cutbacks in defense spending, and an overbuilt real
estate market.  There can be no assurance that the State economy will not
experience worse-than-predicted results in the 1995-96 fiscal year, with
corresponding material and adverse effects on the State's projections of
receipts and disbursements.

          The unemployment rate in the State dipped below the national rate in
the second half of 1981 and remained lower until 1991.  It stood at 6.9% in
1994.  The total employment growth rate in the State has been below the national
average since 1984 and is expected to slow to less than 0.5% in 1995.  State per
capita personal income remains above the national average.  State per capita
income for 1994 was estimated at $25,999, which is 19.2% above the 1994
estimated national average of $21,809. During the past ten years, total personal
income in the State rose slightly faster than the national average only in 1986
through 1989.

State Budget.  The State Constitution requires the governor (the "Governor") to
------------                                                                   
submit to the State legislature (the "Legislature") a balanced executive budget
which contains a complete plan of expenditures for the ensuing fiscal year and
all moneys and revenues estimated to be available therefor, accompanied by bills
containing all proposed appropriations or reappropriations and any new or
modified revenue measures to be enacted in connection with the executive budget.
The entire plan constitutes the proposed State financial plan for that fiscal
year.  The Governor is required to submit to the Legislature quarterly budget
updates which include a revised cash-basis state financial plan, and an
explanation of any changes from the previous state financial plan.

          The State's budget for the 1995-96 fiscal year was enacted by the
Legislature on June 7, 1995, more than two months after the start of the fiscal
year.  Prior to adoption of the budget, the Legislature enacted appropriations
for disbursements considered to be necessary for State operations and other
purposes, including all necessary appropriations for debt service.  The State
financial plan for the 1995-96 fiscal year was formulated on June 20, 1995 and
is based upon the State's budget as enacted by the Legislature and signed into
law by the Governor (the "1995-96 State Financial Plan").

          The 1995-96 State Financial Plan is the first to be enacted in the
administration of the Governor, who assumed office on January 1.  It is the
first budget in over half a century which proposed and, as enacted, projects an
absolute

                                      -8-
<PAGE>
 
year-over-year decline in disbursements in the General Fund, the State's
principal operating fund.  Spending for State operations is projected to drop
even more sharply, by 4.6%.  Nominal spending from all State spending sources
(i.e., excluding Federal aid) is proposed to increase by only 2.5% from the
-----                                                                      
prior fiscal year, in contrast to the prior decade when such spending growth
averaged more than 6.0% annually.

          In his executive budget, the Governor indicated that in the 1995-96
fiscal year, the state financial plan, based on then-current law governing
spending and revenues, would be out of balance by almost $4.7 billion, as a
result of the projected structural deficit resulting from the ongoing disparity
between sluggish growth in receipts, the effect of prior-year tax changes, and
the rapid acceleration of spending growth; the impact of unfunded 1994-95
initiatives, primarily for local aid programs; and the use of one-time
solutions, primarily surplus funds from the prior year, to fund recurring
spending in the 1994-95 budget.  The Governor proposed additional tax cuts to
spur economic growth and provide relief for low and middle-income tax payers,
which were larger than those ultimately adopted, and which added $240 million to
the then projected imbalance or budget gap, bringing the total to approximately
$5 billion.

          This gap is projected to be closed in the 1995-96 State Financial Plan
through a series of actions, mainly spending reductions and cost containment
measures and certain reestimates that are expected to be recurring, but also
through the use of one-time solutions.  The 1995-96 State Financial Plan
projects (i) nearly $1.6 billion in savings from cost containment, disbursement
reestimates, and other savings in social welfare programs, including Medicaid,
income maintenance and various child and family care programs; (ii) $2.2 billion
in savings from State agency actions to reduce spending on the State workforce,
SUNY and CUNY, mental hygiene programs, capital projects, the prison system and
fringe benefits; (iii) $300 million in savings from local assistance reforms,
including actions affecting school aid and revenue sharing while proposing
program legislation to provide relief from certain mandates that increase local
spending; (iv) over $400 million in revenue measures, primarily through a new
Quick Draw Lottery game, changes to tax payments schedules, and the sale of
assets; and (v) $300 million from reestimates in receipts.

          The 1995-96 State Financial Plan includes actions that will have an
effect on the budget outlook for State fiscal year 1996-97 and beyond.  The
Division of the Budget estimates that the 1995-96 State Financial Plan contains
actions that provide nonrecurring resources or savings totalling approximately
$900 million while the State comptroller (the "Comptroller") believes that such
amount exceeds $1 billion.  In addition to this use of nonrecurring resources,
the 1995-96 State Financial Plan reflects

                                      -9-
<PAGE>
 
actions that will directly affect the State's 1996-97 fiscal year baseline
receipts and disbursements.  The three-year plan to reduce State personal income
taxes will decrease State tax receipts by an estimated $1.7 billion in State
fiscal year 1996-97 in addition to the amount of reduction in State fiscal year
1995-96.  Further significant reductions in the personal income tax are
scheduled for the 1997-98 State fiscal year.  Other tax reductions enacted in
1994 and 1995 are estimated to cause an additional reduction in receipts of over
$500 million in 1996-97, as compared to the level of receipts in 1995-96.
Similarly, many actions taken to reduce disbursements in the State's 1995-96
fiscal year are expected to provide greater reductions in the State's fiscal
year 1996-97.  These include actions to reduce the State workforce, reduce
Medicaid and welfare expenditures and slow community mental hygiene program
development.

          The Division of the Budget and the Comptroller expect that the net
impact of these and other factors will produce a potential imbalance in receipts
and disbursements in fiscal year 1996-97.  The Governor has indicated that in
the 1996-97 executive budget he will propose to close this potential imbalance
primarily through General Fund expenditure reductions and without increases in
taxes or deferrals of scheduled tax reductions.

          The 1995-96 State Financial Plan is based on a number of assumptions
and projections.  Because it is not possible to predict accurately the
occurrence of all factors that may affect the 1995-96 State Financial Plan,
actual results could differ materially and adversely from projections made at
the outset of a fiscal year.  There can be no assurance that the State will not
face substantial potential budget gaps in future years resulting from a
significant disparity between tax revenues projected from a lower recurring
receipts base and the spending required to maintain State programs at current
levels.  To address any potential budgetary imbalance, the State may need to
take significant actions to align recurring receipts and disbursements in future
fiscal years.

Recent Financial Results.  The General Fund is the principal operating fund of
------------------------                                                      
the State and is used to account for all financial transactions, except those
required to be accounted for in another fund.  It is the State's largest fund
and receives almost all State taxes and other resources not dedicated to
particular purposes.

          The General Fund is projected to be balanced on a cash basis for the
1995-96 fiscal year.  Total receipts and transfers from other funds are
projected to be $33.110 billion, a decrease of $48 million from total receipts
in the prior fiscal year.  Total General Fund disbursements and transfers to
other funds are

                                     -10-
<PAGE>
 
projected to be $33.055 billion, a decrease of $344 million from the total
amount disbursed in the prior fiscal year.

          The State's financial position on a GAAP (generally accepted
accounting principles) basis as of March 31, 1993 included a 1991-92 accumulated
deficit in its combined governmental funds of $681 million.  Liabilities
totalled $12.864 billion and assets of $12.183 billion were available to
liquidate these liabilities.

          The State's financial operations have improved during recent fiscal
years.  During the period 1989-90 through 1991-92, the State incurred General
Fund operating deficits that were closed with receipts from the issuance of tax
and revenue anticipation notes.  The national recession and then the lingering
economic slowdown in the New York and regional economy, resulted in repeated
shortfall in receipts and three budget deficits.  For its 1992-93, 1993-94 and
1994-95 fiscal years, however, the State recorded balanced budgets on a cash
basis, with substantial fund balances in 1992-93 and 1993-94, and a smaller fund
balance in 1994-95.

Debt Limits and Outstanding Debt.  There are a number of methods by which the
--------------------------------                                             
State of New York may incur debt.  Under the State Constitution, the State may
not, with limited exceptions for emergencies, undertake long-term general
obligation borrowing (i.e., borrowing for more than one year) unless the
                      ----                                              
borrowing is authorized in a specific amount for a single work or purpose by the
Legislature and approved by the voters.  There is no limitation on the amount of
long-term general obligation debt that may be so authorized and subsequently
incurred by the State.

          The State may undertake short-term borrowings without voter approval
(i) in anticipation of the receipt of taxes and revenues, by issuing tax and
revenue anticipation notes, and (ii) in anticipation of the receipt of proceeds
from the sale of duly authorized but unissued general obligation bonds, by
issuing bond anticipation notes.  The State may also, pursuant to specific
constitutional authorization, directly guarantee certain obligations of the
State of New York's authorities and public benefit corporations ("Authorities").
Payments of debt service on New York State general obligation and New York
State-guaranteed bonds and notes are legally enforceable obligations of the
State of New York.

          The State employs additional long-term financing mechanisms, lease-
purchase and contractual-obligation financings, which involve obligations of
public authorities or municipalities that are State-supported but are not
general obligations of the State.  Under these financing arrangements, certain
public authorities and municipalities have issued obligations to finance the
construction and rehabilitation of facilities or the

                                     -11-
<PAGE>
 
acquisition and rehabilitation of equipment, and expect to meet their debt
service requirements through the receipt of rental or other contractual payments
made by the State.  Although these financing arrangements involve a contractual
agreement by the State to make payments to a public authority, municipality or
other entity, the State's obligation to make such payments is generally
expressly made subject to appropriation by the Legislature and the actual
availability of money to the State for making the payments.  The State has also
entered into a contractual-obligation financing arrangement with the Local
Government Assistance Corporation ("LGAC") in an effort to restructure the way
the State makes certain local aid payments.

          In 1990, as part of a State fiscal reform program, legislation was
enacted creating LGAC, a public benefit corporation empowered to issue long-term
obligations to fund certain payments to local governments traditionally funded
through New York State's annual seasonal borrowing.  The legislation empowered
LGAC to issue its bonds and notes in an amount not in excess of $4.7 billion
(exclusive of certain refunding bonds) plus certain other amounts.  Over a
period of years, the issuance of these long-term obligations, which are to be
amortized over no more than 30 years, was expected to eliminate the need for
continued short-term seasonal borrowing.   The legislation also dedicated
revenues equal to one-quarter of the four cent State sales and use tax to pay
debt service on these bonds.  The legislation also imposed a cap on the annual
seasonal borrowing of the State at $4.7 billion, less net proceeds of bonds
issued by LGAC and bonds issued to provide for capitalized interest, except in
cases where the Governor and the legislative leaders have certified the need for
additional borrowing and provided a schedule for reducing it to the cap.  If
borrowing above the cap is thus permitted in any fiscal year, it is required by
law to be reduced to the cap by the fourth fiscal year after the limit was first
exceeded.  As of June 1995, LGAC had issued bonds to provide net proceeds of
$4.7 billion, completing the program.  The impact of LGAC's borrowing is that
the State is able to meet its cash flow needs in the first quarter of the fiscal
year without relying on short-term seasonal borrowings.  The 1995-96 State
Financial Plan includes no spring borrowing nor did the 1994-95 State Financial
Plan, which was the first time in 35 years there was no short-term seasonal
borrowing.

          In June 1994, the Legislature passed a proposed constitutional
amendment that would significantly change the long-term financing practices of
the State and its public authorities.  The proposed amendment would permit the
State, within a formula-based cap, to issue revenue bonds, which would be debt
of the State secured solely by a pledge of certain State tax receipts (including
those allocated to State funds dedicated for transportation purposes), and not
by the full faith and

                                     -12-
<PAGE>
 
credit of the State.  In addition, the proposed amendment would (i) permit
multiple purpose general obligation bond proposals to be proposed on the same
ballot, (ii) require that State debt be incurred only for capital projects
included in a multi-year capital financing plan, and (iii) prohibit, after its
effective date, lease-purchase and contractual-obligation financing mechanisms
for State facilities.

          Before the approved constitutional amendment can be presented to the
voters for their consideration, it must be passed by a separately elected
legislature.  The amendment must therefore be passed by the newly elected
Legislature in 1995 prior to presentation to the voters in November 1995.  The
amendment was passed by the Senate in June 1995, and the Assembly is expected to
pass the amendment shortly.

          On January 13, 1992, Standard & Poor's Corporation ("Standard &
Poor's") reduced its ratings on the State's general obligation bonds from A to
A- and, in addition, reduced its ratings on the State's moral obligation, lease
purchase, guaranteed and contractual obligation debt.  Standard & Poor's also
continued its negative rating outlook assessment on State general obligation
debt.  On April 26, 1993, Standard & Poor's revised the rating outlook
assessment to stable.  On February 14, 1994, Standard & Poor's raised its
outlook to positive and, on February 28, 1994, confirmed its A- rating.  On
January 6, 1992, Moody's Investors Service, Inc. ("Moody's") reduced its ratings
on outstanding limited-liability State lease purchase and contractual
obligations from A to Baa1.  On February 28, 1994, Moody's reconfirmed its A
rating on the State's general obligation long-term indebtedness.

          The State anticipates that its capital programs will be financed, in
part, by State and public authorities borrowings in 1995-96.  The State expects
to issue $248 million in general obligation bonds (including $170 million for
purposes of redeeming outstanding bond anticipation notes) and $186 million in
general obligation commercial paper.  The Legislature has also authorized the
issuance of up to $33 million in certificates of participation during the
State's 1995-96 fiscal year for equipment purchases and $14 million for capital
purposes.  These projections are subject to change if circumstances require.

          Principal and interest payments on general obligation bonds and
interest payments on bond anticipation notes and on tax and revenue anticipation
notes were $793.3 million for the 1994-95 fiscal year, and are estimated to be
$774.4 million for the 1995-96 fiscal year.  These figures do not include
interest payable on State General Obligation Refunding Bonds issued in July 1992
("Refunding Bonds") to the extent that such interest was paid from an escrow
fund established with the proceeds of such Refunding Bonds.  Principal and
interest payments on fixed

                                     -13-
<PAGE>
 
rate and variable rate bonds issued by LGAC were $239.4 million for the 1994-95
fiscal year, and are estimated to be $328.2 million for 1995-96.  State lease-
purchase rental and contractual obligation payments for 1994-95, including State
installment payments relating to certificates of participation, were $1.607
billion and are estimated to be $1.641 billion in 1995-96.

          New York State has never defaulted on any of its general obligation
indebtedness or its obligations under lease-purchase or contractual-obligation
financing arrangements and has never been called upon to make any direct
payments pursuant to its guarantees.

Litigation.  Certain litigation pending against New York State or its officers
----------                                                                    
or employees could have a substantial or long-term adverse effect on New York
State finances.  Among the more significant of these cases are those that
involve (1) the validity of agreements and treaties by which various Indian
tribes transferred title to New York State of certain land in central and
upstate New York; (2) certain aspects of New York State's Medicaid policies,
including its rates, regulations and procedures; (3) action against New York
State and New York City officials alleging inadequate shelter allowances to
maintain proper housing; (4) challenges to the practice of reimbursing certain
Office of Mental Health patient care expenses from the client's Social Security
benefits; (5) alleged responsibility of New York State officials to assist in
remedying racial segregation in the City of Yonkers; (6) challenges by
commercial insurers, employee welfare benefit plans, and health maintenance
organizations to the imposition of 13%, 11% and 9% surcharges on inpatient
hospital bills and a bad debt and charity care allowance on all hospital bills
and hospital bills paid by such entities; (7) challenges to certain aspects of
petroleum business taxes, and (8) action alleging damages resulting from the
failure by the State's Department of Environmental Conservation to timely
provide certain data.

          A number of cases have also been instituted against the State
challenging the constitutionality of various public authority financing
programs.

          In a proceeding commenced on August 6, 1991 (Schulz, et al. v. State
                                                       -----------------------
of New York, et al., Supreme Court, Albany County), petitioners challenge the
-------------------                                                          
constitutionality of two bonding programs of the New York State Thruway
Authority authorized by Chapters 166 and 410 of the Laws of 1991.  In addition,
petitioners challenge the fiscal year 1991-92 judiciary budget as having been
enacted in violation of Sections 1 and 2 of Article VII of the State
Constitution.  The defendants' motion to dismiss the action on procedural
grounds was denied by order of the Supreme Court dated January 2, 1992.  By
order dated November 5, 1992, the Appellate Division, Third Department, reversed
the

                                     -14-
<PAGE>
 
order of the Supreme Court and granted defendants' motion to dismiss on grounds
of standing and mootness.  By order dated September 16, 1993, on motion to
reconsider, the Appellate Division, Third Department, ruled that plaintiffs have
standing to challenge the bonding program authorized by Chapter 166 of the laws
of 1991.  The proceeding is presently pending in Supreme Court, Albany County.

          In Schulz, et al. v. State of New York, et al., commenced May 24,
             -------------------------------------------                   
1993, Supreme Court, Albany County, petitioners challenge, among other things,
the constitutionality of, and seek to enjoin, certain highway, bridge and mass
transportation bonding programs of the New York State Thruway Authority and the
Metropolitan Transportation Authority authorized by Chapter 56 of the Laws of
1993.  Petitioners contend that the application of State tax receipts held in
dedicated transportation funds to pay debt service on bonds of the Thruway
Authority and of the Metropolitan Transportation Authority violates Sections 8
and 11 of Article VII and Section 5 of Article X of the State Constitution and
due process provisions of the State and Federal Constitutions.  By order dated
July 27, 1993, the Supreme Court granted defendants' motions for summary
judgment, dismissed the complaint, and vacated the temporary restraining order
previously issued.  By decision dated October 21, 1993, the Appellate Division,
Third Department, affirmed the judgment of the Supreme Court.  On June 30, 1994,
the Court of Appeals unanimously affirmed the rulings of the trail court and the
Appellate Division in favor of the State.

          Several actions challenging the constitutionality of legislation
enacted during the 1990 legislative session which changed actuarial funding
methods for determining state and local contributions to state employee
retirement systems have been decided against the State.  As a result, the
Comptroller has developed a plan to restore the State's retirement systems to
prior funding levels.  Such funding is expected to exceed prior levels by $30
million in fiscal 1994-95, $63 million in fiscal 1995-96, $116 million in fiscal
1996-97, $193 million in fiscal 1997-98, peaking at $241 million in fiscal 1998-
99.  Beginning in fiscal 2001-02, State contributions required under the
Comptroller's plan are projected to be less than that required under the prior
funding method.  As a result of the United States Supreme Court decision in the
case of State of Delaware v. State of New York, on January 21, 1994, the State
        -----------------    -----------------                                
entered into a settlement agreement with various parties.  Pursuant to all
agreements executed in connection with the action, the State is required to make
aggregate payments of $351.4 million, of which $90.3 million have been made.
Annual payments to the various parties will continue through the State's 2002-03
fiscal year in amounts which will not exceed $48.4 million in any fiscal year
subsequent to the State's 1994-95 fiscal year.

                                     -15-

          The legal proceedings noted above involve State finances, State
programs and miscellaneous tort, real property and contract claims in which the
State is a defendant and the monetary damages sought are substantial.  These
proceedings could affect adversely the financial condition of the State.
Adverse developments in these proceedings or the initiation of new proceedings
could affect the ability of the State to maintain a balanced 1995-96 State
Financial Plan.  An adverse decision in any of these proceedings could exceed
the amount of the 1995-96 State Financial Plan reserve for the payment of
judgments and, therefore, could affect the ability of the State to maintain a
balanced 1995-96 State Financial Plan.  In its audited financial statements for
the fiscal year ended March 31, 1994, the State reported its estimated liability
for awarded and anticipated unfavorable judgments to be $675 million.

          Although other litigation is pending against New York State, except as
described above, no current litigation involves New York State's authority, as a
matter of law, to contract indebtedness, issue its obligations, or pay such
indebtedness when it matures, or affects New York State's power or ability, as a
matter of law, to impose or collect significant amounts of taxes and revenues.

Authorities.  The fiscal stability of New York State is related, in part, to the
-----------                                                                     
fiscal stability of its Authorities, which generally have responsibility for
financing, constructing and operating revenue-producing public benefit
facilities.  Authorities are not subject to the constitutional restrictions on
the incurrence of debt which apply to the State itself, and may issue bonds and
notes within the amounts of, and as otherwise restricted by, their legislative
authorization.  The State's access to the public credit markets could be
impaired, and the market price of its outstanding debt may be materially and
adversely affected, if any of the Authorities were to default on their
respective obligations, particularly with respect to debt that are State-
supported or State-related.  As of September 30, 1994, date of the latest data
available, there were 18 Authorities that had outstanding debt of $100 million
or more.  The aggregate outstanding debt, including refunding bonds, of these 18
Authorities was $70.3 billion.  As of March 31, 1995, aggregate public authority
debt outstanding as State-supported debt was $27.9 billion and as State-related
debt was $36.1 billion.

          Authorities are generally supported by revenues generated by the
projects financed or operated, such as fares, user fees on bridges, highway
tolls and rentals for dormitory rooms and housing.  In recent years, however,
New York State has provided financial assistance through appropriations, in some
cases of a recurring nature, to certain of the 18 Authorities for operating and
other expenses and, in fulfillment of its commit-

                                     -16-
<PAGE>
 
ments on moral obligation indebtedness or otherwise, for debt service.  This
operating assistance is expected to continue to be required in future years.  In
addition, certain statutory arrangements provide for State local assistance
payments otherwise payable to localities to be made under certain circumstances
to certain Authorities.  The State has no obligation to provide additional
assistance to localities whose local assistance payments have been paid to
Authorities under these arrangements.  However, in the event that such local
assistance payments are so diverted, the affected localities could seek
additional State funds.

New York City and Other Localities.  The fiscal health of the State of New York
----------------------------------                                             
may also be impacted by the fiscal health of its localities, particularly the
City of New York, which has required and continues to require significant
financial assistance from New York State.  The City depends on State aid both to
enable the City to balance its budget and to meet its cash requirements.  The
City has achieved balanced operating results for each of its fiscal years since
1981 as reported in accordance with the then-applicable GAAP.

          In 1975, New York City suffered a fiscal crisis that impaired the
borrowing ability of both the City and New York State.  In that year the City
lost access to public credit markets.  The City was not able to sell short-term
notes to the public again until 1979.

          In 1975, Standard & Poor's suspended its A rating of City bonds.  This
suspension remained in effect until March 1981, at which time the City received
an investment grade rating of BBB from Standard & Poor's.  On July 2, 1985,
Standard & Poor's revised its rating of City bonds upward to BBB+ and on
November 19, 1987, to A-.  On July 2, 1993, Standard & Poor's reconfirmed its A-
rating of City bonds, continued its negative rating outlook assessment and
stated that maintenance of such rating depended upon the City's making further
progress towards reducing budget gaps in the outlying years.  Moody's ratings of
City bonds were revised in November 1981 from B (in effect since 1977) to Ba1,
in November 1983 to Baa, in December 1985 to Baa1, in May 1988 to A and again in
February 1991 to Baa1.  On July 10, 1995, Standard & Poor's downgraded its
rating on the City's $23 billion of outstanding general obligation bonds to
"BBB+" from "A-", citing to the City's chronic structural budget problems and
weak economic outlook.  Standard & Poor's stated that New York City's reliance
on one-time revenue measures to close annual budget gaps, a dependence on
unrealized labor savings, overly optimistic estimates of revenues and state and
federal aid and the City's continued high debt levels also contributed to its
decision to lower the rating.

          New York City is heavily dependent on New York State and federal
assistance to cover insufficiencies in its revenues.  There can be no assurance
that in the future federal and State assistance will enable the City to make up
its budget deficits.  To help alleviate the City's financial difficulties, the
Legislature created the Municipal Assistance Corporation ("MAC") in 1975.  MAC
is authorized to issue bonds and notes payable from certain stock transfer tax
revenues, from the City's portion of the State sales tax derived in the City and
from State per capita aid otherwise payable by the State to the City.  Failure
by the State to continue the imposition of such taxes, the reduction of the rate
of such taxes to rates less than those in effect on July 2, 1975, failure by the
State to pay such aid revenues and the reduction of such aid revenues below a
specified level are included among the events of default in the resolutions
authorizing MAC's long-term debt.  The occurrence of an event of default may
result in the acceleration of the maturity of all or a portion of MAC's debt.
MAC bonds and notes constitute general obligations of MAC and do not constitute
an enforceable obligation or debt of either the State or the City.  Under its
enabling legislation, MAC's authority to issue bonds and notes (other than
refunding bonds and notes) expired on December 31, 1984.  Legislation has been
passed by the legislature which would, under certain conditions, permit MAC to
issue up to $1.465 billion of additional bonds, which are not subject to a moral
obligation provision.

          Since 1975, the City's financial condition has been subject to
oversight and review by the New York State Financial Control Board (the "Control
Board") and since 1978 the City's financial statements have been audited by
independent accounting firms.  To be eligible for guarantees and assistance, the
City is required during a "control period" to submit annually for Control Board
approval, and when a control period is not in effect for Control Board review, a
financial plan for the next four fiscal years covering the City and certain
agencies showing balanced budgets determined in accordance with GAAP.  New York
State also established the Office of the State Deputy Comptroller for New York
City ("OSDC") to assist the Control Board in exercising its powers and
responsibilities.  On June 30, 1986, the City satisfied the statutory
requirements for termination of the control period.  This means that the Control
Board's powers of approval are suspended, but the Board continues to have
oversight responsibilities.

          The staffs of OSDC, the Control Board and the City comptroller issue
periodic reports on the City's financial plans, as modified, analyzing forecasts
of revenues and expenditures, cash flow, and debt service requirements, as well
as compliance with the financial plan, as modified, by the City and its Covered
Organizations (i.e., those which receive or may receive monies from the City
directly, indirectly or contingently).  OSDC staff

                                     -18-
<PAGE>
 
reports issued during the mid-1980's noted that the City's budgets benefited
from a rapid rise in the City's economy, which boosted the City's collection of
property, business and income taxes.  These resources were used to increase the
City's workforce and the scope of discretionary and mandated City services.
Subsequent OSDC staff reports examined the 1987 stock market crash and the 1989-
92 recession, which affected the City's region more severely than the nation,
and attributed an erosion of City revenues and increasing strain on City
expenditures to that recession.  According to a recent OSDC staff report, the
City's economy was slow to recover from the recession and is expected to
experience a weak employment situation, and moderate wage and income growth,
during the 1995-96 period.  Also, reports of OSDC, the Control Board and the
City comptroller have variously indicated that many of the City's balanced
budgets have been accomplished, in part, through the use of non-recurring
resources, tax and fee increases, personnel reduction and additional State
assistance; that the City has not yet brought its long-term expenditures in line
with recurring revenues; that the City's proposed gap-closing programs, if
implemented, would narrow future budget gaps; that these programs tend to rely
heavily on actions outside the direct control of the City; and that the City is
therefore likely to continue to face future projected budget gaps requiring the
City to increase revenues and/or reduce expenditures.  According to the most
recent staff reports of OSDC, the Control Board and the comptroller, during the
four-year period covered by the current financial plan, the City is relying on
obtaining substantial resources from initiatives needing approval and
cooperation of its municipal labor unions, Covered Organizations and city
council, as well as the state and federal governments, among others, and there
can be no assurance that such approval can be obtained.

          On February 14, 1995, the Mayor released the preliminary budget for
the City's 1996 fiscal year, which addressed a projected $2.7 billion budget
gap.  Most of the gap-closing initiatives may be implemented only with the
cooperation of the City's municipal unions, or the State or federal governments.

          New York City officials estimated that the final State budget, enacted
by the Legislature on June 7, 1995, would result in a $670 million shortfall
from the $1.1 billion in additional state aid the Mayor had sought in order to
close the City's projected deficit.  The City may have to take drastic actions
to balance its budget in the wake of such shortfall.

          Although the City has balanced its budget since 1981, estimates of the
City's revenues and expenditures, which are based on numerous assumptions, are
subject to various uncertainties. If expected federal or State aid is not
forthcoming, if unforeseen developments in the economy significantly

                                     -19-
<PAGE>
 
reduce revenues derived from economically sensitive taxes or necessitate
increased expenditures for public assistance, if the City should negotiate wage
increases for its employees greater than the amounts provided for in the City's
financial plan or if other uncertainties materialize that reduce expected
revenues or increase projected expenditures, then, to avoid operating deficits,
the City may be required to implement additional actions, including increases in
taxes and reductions in essential City services.  The City might also seek
additional assistance from New York State.

          The City requires certain amounts of financing for seasonal and
capital spending purposes.  The City has issued $1.75 billion of notes for
seasonal financing purposes during fiscal year 1994.  The City's capital
financing program projected long-term financing requirements of approximately
$17 billion for the City's fiscal years 1995 through 1998.  The major capital
requirements include expenditures for the City's water supply and sewage
disposal systems, roads, bridges, mass transit, schools, hospitals and housing.
In addition to financing for new purposes, the City and the New York City
Municipal Water Finance Authority have issued refunding bonds totalling $1.8
billion in fiscal year 1994.

          Certain localities, in addition to the City, could have financial
problems leading to requests for additional New York State assistance.  The
potential impact on the State of such requests by localities was not included in
the projections of the State's receipts and disbursements in the State's 1995-96
fiscal year.

          Fiscal difficulties experienced by the City of Yonkers ("Yonkers")
resulted in the creation of the Financial Control Board for the City of Yonkers
(the "Yonkers Board") by New York State in 1984. The Yonkers Board is charged
with oversight of the fiscal affairs of Yonkers.  Future actions taken by the
Governor or the Legislature to assist Yonkers could result in allocation of New
York State resources in amounts that cannot yet be determined.

          Municipalities and school districts have engaged in substantial short-
term and long-term borrowings.  In 1993, the total indebtedness of all
localities in New York State other than New York City was approximately $17.7
billion.  A small portion (approximately $105 million) of that indebtedness
represented borrowing to finance budgetary deficits and was issued pursuant to
enabling New York State legislation.  State law requires the comptroller to
review and make recommendations concerning the budgets of those local government
units other than New York City authorized by State law to issue debt to finance
deficits during the period that such deficit financing is outstanding.  Fifteen

                                     -20-
<PAGE>
 
localities had outstanding indebtedness for deficit financing at the close of
their fiscal year ending in 1993.

          From time to time, federal expenditure reductions could reduce, or in
some cases eliminate, federal funding of some local programs and accordingly
might impose substantial increased expenditure requirements on affected
localities.  If New York State, New York City or any of the Authorities were to
suffer serious financial difficulties jeopardizing their respective access to
the public credit markets, the marketability of notes and bonds issued by
localities within New York State could be adversely affected.  Localities also
face anticipated and potential problems resulting from certain pending
litigation, judicial decisions and long-range economic trends.  Long-range
potential problems of declining urban population, increasing expenditures and
other economic trends could adversely affect localities and require increasing
New York State assistance in the future.

Services, Corp. on the premises of their financial institutions.  In addition,
no sales load is charged on the reinvestment of dividends or distributions or in
connection with certain share exchange transactions.  Investors who have
previously redeemed shares in a portfolio of Master Fund or Master Tax-Exempt
Fund on which a sales load has been paid also have a one-time privilege of
purchasing shares of another portfolio of either company at net asset value
without a sales charge, provided that such privilege will apply only to
                        --------                                       
purchases made within 30 calendar days from the date of redemption and only with
respect to the amount of the redemption.

          Total sales charges paid by shareholders of the New York Intermediate-
Term Tax-Exempt Fund for the fiscal years ended March 31, 1995, 1994 and 1993
were $0, $2,243 and $3,048, respectively.  Of these amounts, UST Distributors,
Inc., the Fund's former distributor, retained $0, $1,750 and $915, respectively.
The balance was paid to selling dealers.

          Master Tax-Exempt Fund may suspend the right of redemption or postpone
the date of payment for Shares for more than seven days during any period when
(a) trading on the New York Stock Exchange (the "Exchange") is restricted by
applicable rules and regulations of the Securities and Exchange Commission; (b)
the Exchange is closed for other than customary weekend and holiday closings;
(c) the Securities and Exchange Commission has by order permitted such
suspension; or (d) an emergency exists as determined by the Securities and
Exchange Commission.

          In the event that Shares are redeemed in cash at their net asset
value, a shareholder may receive in payment for such Shares an amount that is
more or less than his original investment due to changes in the market price of
the Fund's portfolio securities.

          Under limited circumstances, Master Tax-Exempt Fund may accept
securities as payment for Shares.  Securities acquired in this manner will be
limited to securities issued in transactions involving a bona fide

reorganization or statutory merger, or will be limited to other securities
(except for municipal debt securities issued by state political subdivisions or
their agencies or instrumentalities) that: (a) meet the investment objective and
policies of any Fund acquiring such securities; (b) are acquired for investment
and not for resale; (c) are liquid securities that are not restricted as to
transfer either by law or liquidity of market; and (d) have a value that is
readily ascertainable (and not established only by evaluation procedures) as
evidenced by a listing on the American Stock Exchange, New York Stock Exchange
or NASDAQ, or as evidenced by their status as U.S. Government securities, bank
certificates of deposit, banker's acceptances, corporate and other debt
securities that

                               INVESTOR PROGRAMS
                               -----------------


Systematic Withdrawal Plan
--------------------------

          An Investor who owns Shares with a value of $10,000 or more may begin
a Systematic Withdrawal Plan.  The withdrawal can be on a monthly, quarterly,
semiannual or annual basis.  There are four options for such systematic
withdrawals.  The Investor may request:

     (1)  A fixed-dollar withdrawal;

     (2)  A fixed-share withdrawal;

     (3)  A fixed-percentage withdrawal (based on the current value of the
          account); or

     (4)  A declining-balance withdrawal.

Prior to participating in a Systematic Withdrawal Plan, the Investor must
deposit any outstanding certificates for Shares with Mutual Funds Service
Company, the Fund's sub-transfer agent.  Under this Plan, dividends and
distributions are automatically reinvested in additional Shares.  Amounts paid
to Investors under this Plan should not be considered as income.  Withdrawal
payments represent proceeds from the sale of Shares, and there will be a
reduction of the shareholder's equity in the Fund if the amount of the
withdrawal payments exceeds the dividends and distributions paid on the Shares
and the appreciation of the Investor's investment in the Fund.  This in turn may
result in a complete depletion of the shareholder's investment.  An Investor may
not participate in a program of systematic investing in the Fund while at the
same time participating in the Systematic Withdrawal Plan with respect to an
account in the Fund.


Exchange Privilege
------------------

          Investors and Customers of Shareholder Organizations may exchange
Shares having a value of at least $500 for Shares of any other portfolio of
Master Fund or Master Tax-Exempt Fund (collectively, the "Companies").  Shares
may be exchanged by wire, telephone or mail and must be made to accounts of
identical registration.  There is no exchange fee imposed by the Companies.  In
order to prevent abuse of this privilege to the disadvantage of other
shareholders, the Companies reserve the right to limit the number of exchange
requests of Investors and Customers of

                                     -25-
<PAGE>
 
Shareholder Organizations to no more than six per year.  The Companies may
modify or terminate the exchange program at any time upon 60 days' written
notice to shareholders, and may reject any exchange request.

          For Federal income tax purposes, exchanges are treated as sales on
which the shareholder will realize a gain or loss, depending upon whether the
value of the Shares to be given up in exchange is more or less than the basis in
such Shares at the time of the exchange.  Generally, a shareholder may include
sales loads incurred upon the purchase of Shares in his or her tax basis for
such Shares for the purpose of determining gain or loss on a redemption,
transfer or exchange of such Shares.  However, if the shareholder effects an
exchange of Shares for shares of another portfolio of the Companies within 90
days of the purchase and is able to reduce the sales load applicable to the new
shares (by virtue of the Companies' exchange privilege), the amount equal to
such reduction may not be included in the tax basis of the shareholder's
exchanged Shares but may be included (subject to the limitation) in the tax
basis of the new shares.

Other Investor Programs
-----------------------

          As described in the Prospectus, Shares of the Funds may be purchased
in connection with the Automatic Investment Program.


                          DESCRIPTION OF CAPITAL STOCK
                          ----------------------------

          Master Tax-Exempt Fund's Charter authorizes its Board of Directors to
issue up to 14 billion full and fractional shares of capital stock and to
classify or reclassify any unissued shares of Master Tax-Exempt Fund into one or
more additional classes or series by setting or changing in any one or more
respects their respective preferences, conversion or other rights, voting
powers, restrictions, limitations as to dividends, qualifications, and terms and
conditions of redemption.  The Prospectus describes the classes of shares into
which Master Tax-Exempt Fund's authorized capital is currently classified.

          Shares have no preemptive rights and only such conversion or exchange
rights as the Board of Directors may grant in its discretion.  When issued for
payment as described in the Prospectus, Shares will be fully paid and non-
assessable.  In the event of a liquidation or dissolution of the Fund, its
shareholders are entitled to receive the assets available for distribution
belonging to the Fund and a proportionate distribution, based upon the relative
asset values of Master Tax-Exempt Fund's portfolios, of any general assets of
Master Tax-Exempt Fund not belonging to any particular portfolio of Master Tax-
Exempt Fund which are available for distribution.  In the event of a liquidation
or dissolution of Master Tax-Exempt Fund,

                                     -26-
<PAGE>
 
its shareholders will be entitled to the same distribution process.

          Shareholders of Master Tax-Exempt Fund are entitled to one vote for
each full share held, and fractional votes for fractional shares held, and will
vote in the aggregate and not by class, except as otherwise required by the 1940
Act or other applicable law or when the matter to be voted upon affects only the
interests of the shareholders of a particular class.  Voting rights are not
cumulative and, accordingly, the holders of more than 50% of the aggregate of
the outstanding shares of Master Tax-Exempt Fund may elect all of Master Tax-
Exempt Fund's directors, regardless of the votes of other shareholders.

          Rule 18f-2 under the 1940 Act provides that any matter required to be
submitted to the holders of the outstanding voting securities of an investment
company such as Master Tax-Exempt Fund shall not be deemed to have been
effectively acted upon unless approved by the holders of a majority of the
outstanding shares of each portfolio affected by the matter.  A portfolio is
affected by a matter unless it is clear that the interests of each portfolio in
the matter are substantially identical or that the matter does not affect any
interest of the portfolio.  Under the Rule, the approval of an investment
advisory agreement or any change in a fundamental investment policy would be
effectively acted upon with respect to a portfolio only if approved by a
majority of the outstanding shares of such portfolio.  However, the Rule also
provides that the ratification of the appointment of independent public
accountants, the approval of principal underwriting contracts, and the election
of directors may be effectively acted upon by shareholders of Master Tax-Exempt
Fund voting without regard to class.

          Master Tax-Exempt Fund's Charter authorizes its Board of Directors,
without shareholder approval (unless otherwise required by applicable law), to
(a) sell and convey the assets of the Fund to another management investment
company for consideration which may include securities issued by the purchaser
and, in connection therewith, to cause all outstanding Shares of the Fund to be
redeemed at a price which is equal to their net asset value and which may be
paid in cash or by distribution of the securities or other consideration
received from the sale and conveyance; (b) sell and convert the Fund's assets
into money and, in connection therewith, to cause all outstanding Shares to be
redeemed at their net asset value; or (c) combine the assets belonging to the
Fund with the assets belonging to another portfolio of Master Tax-Exempt Fund,
if the Board of Directors reasonably determines that such combination will not
have a material adverse effect on shareholders of any portfolio participating in
such combination, and, in connection therewith, to cause all outstanding Shares
of the Fund to be redeemed at their net asset value or converted into shares of

                                     -27-
<PAGE>
 
another class of Master Tax-Exempt Fund's capital stock at net asset value.  The
exercise of such authority by the Board of Directors will be subject to the
provisions of the 1940 Act, and the Board of Directors will not take any action
described in this paragraph unless the proposed action has been disclosed in
writing to the Fund's shareholders at least 30 days prior thereto.

          Notwithstanding any provision of Maryland law requiring a greater vote
of Master Tax-Exempt Fund's Common Stock (or of the Shares of the Fund voting
separately as a class) in connection with any corporate action, unless otherwise
provided by law (for example, by Rule 18f-2, discussed above) or by Master Tax-
Exempt Fund's Charter, Master Tax-Exempt Fund may take or authorize such action
upon the favorable vote of the holders of more than 50% of the outstanding
Common Stock of Master Tax-Exempt Fund voting without regard to class.

Investment Advisory and Administration Agreements
-------------------------------------------------

          United States Trust Company of New York serves as Investment Adviser
to the Fund. In the Investment Advisory Agreement, U.S. Trust has agreed to
provide the services described in the Prospectus. The Investment Adviser has
also agreed to pay all expenses incurred by it in connection with its activities
under the agreement other than the cost of securities, including brokerage
commissions, if any, purchased for the Fund. For the fiscal years ended March
31, 1993, 1994 and 1995, Master Tax-Exempt Fund paid the Investment Adviser
$350,352, $505,148 and $449,781, respectively, with respect to the Fund. For the
fiscal years ended March 31, 1995 and 1994, the Investment Adviser waived fees
totalling $17,901 and $1,351 with respect to the Fund.

          The Investment Advisory Agreement provides that the Investment 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 performance of this agreement,
except a loss resulting from a breach of fiduciary duty with respect to the
receipt of compensation for advisory services or a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Investment Adviser
in the performance of its duties or from reckless disregard by it of its duties
and obligations thereunder.  In addition, the Investment Adviser has undertaken
in the Investment Advisory Agreement to maintain its policy and practice of
conducting its Asset Management Group independently of its Banking Group.

          Mutual Funds Service Company ("MFSC") and Federated Administrative
Services, an affiliate of the Distributor, jointly serve as the Fund's
administrators.  Under the Administration Agreement, the administrators have
agreed to maintain office facilities for the Fund, furnish the Fund with
statistical and research data, clerical, accounting and bookkeeping services,
and certain other services required by the Fund, and to compute the net asset
value, net income, "exempt interest dividends" and realized capital gains or
losses of the Fund.  The administrators prepare semiannual reports to the
Securities and Exchange Commission, prepare Federal and state tax returns,
prepare filings with state securities commissions, arrange for and bear the cost
of processing Share purchase and redemption orders, maintain the Fund's
financial accounts and records, and generally assist in all aspects of the
Fund's operations.

          Prior to August 1, 1995, administrative services were provided by MFSC
and Concord Holding Corporation (collectively, the "Administrators") under an
administration agreement having substantially the same terms as the
Administration Agreements currently in effect.  For the fiscal years ended March
31, 1993, 1994 and 1995, Master Tax-Exempt Fund paid the Administrators

                                     -31-
<PAGE>
 
$109,520, $156,257 and $144,024, respectively in the aggregate with respect to
the Fund.  For the fiscal year ended March 31, 1995, the Administrators waived
fees totalling $22 in the aggregate with respect to the Fund.


Service Organizations
---------------------

          As stated in the Prospectus, Master Tax-Exempt Fund will enter into
agreements with Service Organizations.  Such shareholder servicing agreements
will require the Service Organizations to provide shareholder administrative
services to their Customers who beneficially own Shares in consideration for the
Fund's payment (on an annualized basis) of up to .40% of the average daily net
assets of the Fund's Shares beneficially owned by Customers of the Service
Organization.  Such services may include:  (a) assisting Customers in
designating and changing dividend options, account designations and addresses;
(b) providing necessary personnel and facilities to establish and maintain
certain shareholder accounts and records, as may reasonably be requested from
time to time by Master Tax-Exempt Fund; (c) assisting in processing purchases,
exchange and redemption transactions; (d) arranging for the wiring of funds; (e)
transmitting and receiving funds in connection with Customer orders to purchase,
exchange or redeem Shares; (f) verifying and guaranteeing Customer signatures in
connection with redemption orders, transfers among and changes in Customer-
designated accounts; (g) providing periodic statements showing a Customer's
account balances and, to the extent practicable, integrating of such information
with information concerning other client transactions otherwise effected with or
through the Service Organization; (h) furnishing on behalf of Master Tax-Exempt
Fund's distributor (either separately or on an integrated basis with other
reports sent to a Customer by the Service Organization) periodic statements and
confirmations of all purchases, exchanges and redemptions of Shares in a
Customer's account required by applicable federal or state law; (i) transmitting
proxy statements, annual reports, updating prospectuses and other communications
from Master Tax-Exempt Fund to Customers; (j) receiving, tabulating and
transmitting to Master Tax-Exempt Fund proxies executed by Customers with
respect to annual and special meetings of shareholders of Master Tax-Exempt
Fund; (k) providing reports (at least monthly, but more frequently if so
requested by Master Tax-Exempt Fund's distributor) containing state-by-state
listings of the principal residences of the beneficial owners of the Shares; and
(l) providing or arranging for the provision of such other related services as
Master Tax-Exempt Fund or a Customer may reasonably request.

          Master Tax-Exempt Fund's agreements with Service Organizations are
governed by an Administrative Services Plan

                                     -32-
<PAGE>
 
(the "Plan") adopted by Master Tax-Exempt Fund.  Pursuant to the Plan, Master
Tax-Exempt Fund's Board of Directors will review, at least quarterly, a written
report of the amounts expended under Master Tax-Exempt Fund's agreements with
Service Organizations and the purposes for which the expenditures were made.  In
addition, the arrangements with Service Organizations will be approved annually
by a majority of Master Tax-Exempt Fund's directors, including a majority of the
directors who are not "interested persons" of Master Tax-Exempt Fund as defined
in the 1940 Act and have no direct or indirect financial interest in such
arrangements (the "Disinterested Directors").

          Any material amendment to Master Tax-Exempt Fund's arrangements with
Service Organizations must be approved by a majority of the Board of Directors
(including a majority of the Disinterested Directors).  So long as Master Tax-
Exempt Fund's arrangements with Service Organizations are in effect, the
selection and nomination of the members of Master Tax-Exempt Fund's Board of
Directors who are not "interested persons" (as defined in the 1940 Act) of
Master Tax-Exempt Fund will be committed to the discretion of such non-
interested Directors.

          For the fiscal years ended March 31, 1995 and 1994, payments to
Service Organizations totalled $17,923 and $1,351, respectively, with respect to
the New York Intermediate-Term Tax-Exempt Fund, of which $17,458 and $1,351,
respectively, was paid to affiliates of U.S. Trust.

Expenses
--------

          Except as otherwise noted, the Investment Adviser and the
Administrators will bear all expenses in connection with the performance of
their advisory and administrative services. The Fund will bear the expenses
incurred in its operations. Such expenses include taxes; interest; fees,
including the Fund's portion of the fees paid to Master Tax-Exempt Fund's
directors and officers who are not affiliated with the Distributor or the
Administrators; SEC fees; state securities qualification fees; costs of
preparing and printing prospectuses for regulatory purposes and for distribution
to shareholders; advisory, administration and administrative servicing fees;
charges of the custodian, transfer agent and dividend disbursing agent; certain
insurance premiums; outside auditing and legal expenses; cost of independent
pricing services; costs of shareholder reports and meetings; and any
extraordinary expenses. The Fund also pays for any brokerage fees and
commissions in connection with the purchase of portfolio securities.

          If the expenses borne by the Fund in any fiscal year exceed expense
limitations imposed by applicable state securities regulations, the Investment
Adviser and the Administrators will reimburse the Fund for a portion of any such
excess to the extent

                                     -33-
<PAGE>
 
required by such regulations in proportion to the fees received by them in such
year up to the amount of the fees payable to them, provided, however, to the
extent required by such state regulations, the Investment Adviser and the
Administrators have agreed to effect such reimbursement regardless of the fees
payable to them.  The amounts of the above reimbursements, if any, will be
estimated, reconciled and paid on a monthly basis.  To Master Tax-Exempt Fund's
knowledge, of the applicable expense limitations in effect on the date of this
Statement of Additional Information, none is more restrictive than the
following:  2 1/2% of the first $30 million of average annual net assets, 2% of
the next $70 million of average annual net assets and 1/2% of average annual net
assets in excess of $100 million.

Custodian and Transfer Agent
----------------------------

          United States Trust Company of New York also serves as custodian of
the Fund's assets. Under the custodian agreement, U.S. Trust has agreed to (i)
maintain a separate account or accounts in the name of the Fund; (ii) make
receipts and disbursements of money on behalf of the Fund; (iii) collect and
receive all income and other payments and distributions on account of the Fund's
portfolio securities; (iv) respond to correspondence from securities brokers and
others relating to its duties; (v) maintain certain financial accounts and
records; and (vi) make periodic reports to Master Tax-Exempt Fund's Board of
Directors concerning the Fund's operations. U.S. Trust is entitled to monthly
fees for furnishing custodial services according to the following fee schedule:
on the face value of debt securities and the market value of equity securities,
a fee at the annual rate of .05%; on issues held, $50.00 for each physical issue
held, $25.00 for each book-entry issue held and 1/4 of 1% of market value for
each foreign issue held; on transactions, $25.00 for each physical transaction,
$15.00 for each book-entry transaction and $50.00 for each foreign security
transaction. In addition, U.S. Trust is entitled to reimbursement for its 
out-of-pocket expenses in connection with the above services.

          U.S. Trust also serves as the Fund's transfer agent and dividend
disbursing agent.  In such capacity, U.S. Trust has agreed to (i) issue and
redeem Shares; (ii) address and mail all communications by the Fund to its
shareholders, including reports to shareholders, dividend and distribution
notices, and proxy materials for its meetings of shareholders; (iii) respond to
correspondence by shareholders and others relating to its duties; (iv) maintain
shareholder accounts; and (v) make periodic reports to Master Tax-Exempt Fund
concerning the Fund's operations.  For its transfer agency, dividend disbursing,
and subaccounting services, U.S. Trust is entitled to receive $15.00 per annum
per account and subaccount.  In addition, U.S. Trust is entitled to be
reimbursed for its out-of-pocket expenses for the cost of

                                     -34-
<PAGE>
 
forms, postage, processing purchase and redemption orders, handling of proxies,
and other similar expenses in connection with the above services.

          U.S. Trust may, at its own expense, open and maintain custody accounts
with respect to the Fund with other banks or trust companies, and may delegate
its transfer agency obligations to another transfer agent registered or
qualified under applicable law, provided that U.S. Trust shall remain liable for
the performance of all of its custodial and transfer agency duties under the
Custodian and Transfer Agency Agreement, notwithstanding any delegation.
Pursuant to this provision in the agreement, U.S. Trust has entered into a sub-
transfer agency arrangement with MFSC, an affiliate of U.S. Trust, with respect
to accounts of shareholders who are not Customers of U.S. Trust.  For the
services provided by MFSC, U.S. Trust has agreed to pay MFSC $15.00 per annum
per account or subaccount plus out-of-pocket expenses.  MFSC receives no fee
directly from Master Tax-Exempt Fund for any of its sub-transfer agency
services.


                             PORTFOLIO TRANSACTIONS
                             ----------------------

          Subject to the general control of Master Tax-Exempt Fund's Board of
Directors, the Investment Adviser is responsible for, makes decisions with
respect to, and places orders for all purchases and sales of portfolio
securities.

          The Fund may engage in short-term trading to achieve its investment
objective.  Portfolio turnover may vary greatly from year to year as well as
within a particular year.  It is expected that the Fund's turnover rate may be
higher than that of many other investment companies with similar investment
objectives and policies.  The Fund's portfolio turnover rate may also be
affected by cash requirements for redemptions of Shares and by regulatory
provisions which enable the Fund to receive certain favorable tax treatment.
Portfolio turnover will not be a limiting factor in making portfolio decisions.
See "Financial Highlights" in the Fund's prospectus for the Fund's portfolio
turnover rates.

          Securities purchased and sold by the Fund are generally traded in the
over-the-counter market on a net basis (i.e., without commission) through
dealers, or otherwise involve transactions directly with the issuer of an
instrument.  The cost of securities purchased from underwriters includes an
underwriting commission or concession, and the prices at which securities are
purchased from and sold to dealers include a dealer's mark-up or mark-down.
With respect to over-the-counter transactions, the Fund, where possible, will
deal directly with dealers who make a market in the securities involved, except

                                     -35-
<PAGE>
 
in those situations where better prices and execution are available elsewhere.

          The Investment Advisory Agreement provides that, in executing
portfolio transactions and selecting brokers or dealers, the Investment Adviser
will seek to obtain the best net price and the most favorable execution.  The
Investment Adviser shall consider factors it deems relevant, including the
breadth of the market in the security, the price of the security, the financial
condition and execution capability of the broker or dealer and whether such
broker or dealer is selling shares of Master Tax-Exempt Fund, and the
reasonableness of the commission, if any, for the specific transaction and on a
continuing basis.

          In addition, the Investment Advisory Agreement authorizes the
Investment Adviser, to the extent permitted by law and subject to the review of
Master Tax-Exempt Fund's Board of Directors from time to time with respect to
the extent and continuation of the policy, to cause the Fund to pay a broker
which furnishes brokerage and research services a higher commission than that
which might be charged by another broker for effecting the same transaction,
provided that the Investment Adviser determines in good faith that such
commission is reasonable in relation to the value of the brokerage and research
services provided by such broker, viewed in terms of either that particular
transaction or the overall responsibilities of the Investment Adviser to the
accounts as to which it exercises investment discretion.  Such brokerage and
research services might consist of reports and statistics on specific companies
or industries, general summaries of groups of stocks and their comparative
earnings, or broad overviews of the fixed-income market and the economy.

          Supplementary research information so received is in addition to and
not in lieu of services required to be performed by the Investment Adviser and
does not reduce the investment advisory fee payable by the Fund.  Such
information may be useful to the Investment Adviser in serving the Fund and
other clients and, conversely, supplemental information obtained by the
placement of business of other clients may be useful to the Investment Adviser
in carrying out its obligations to the Fund.

          Portfolio securities will not be purchased from or sold to the
Investment Adviser, Distributor, or any affiliated person of either of them (as
such term is defined in the 1940 Act) acting as principal, except to the extent
permitted by the Securities and Exchange Commission.

          Investment decisions for the Fund are made independently from those
for other investment companies, common trust funds and other types of funds
managed by the Investment Adviser.  Such other investment companies and funds
may also invest in the

                                     -36-
<PAGE>
 
same securities as the Fund.  When a purchase or sale of the same security is
made at substantially the same time on behalf of the Fund and another investment
company or common trust fund, the transaction will be averaged as to price, and
available investments allocated as to amount, in a manner which the Investment
Adviser believes to be equitable to the Fund and such other investment company
or common trust 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 by the Fund.  To the extent permitted by law, the Investment
Adviser may aggregate the securities to be sold or purchased for the Fund with
those to be sold or purchased for other investment companies or common trust
funds in order to obtain best execution.

          Ernst & Young LLP, independent auditors, 200 Clarendon Street, Boston,
MA  02116, serve as auditors of Master Tax-Exempt Fund.  The Fund's Financial
Highlights included in the Prospectus and the financial statements for the
period ended March 31, 1995 incorporated by reference in this Statement of
Additional Information have been audited by Ernst & Young LLP for the periods
included in their report thereon which appears therein.

                                    COUNSEL
                                    -------

          Drinker Biddle & Reath (of which Mr. McConnel, Secretary of Master
Tax-Exempt Fund, is a partner), Philadelphia National Bank Building, 1345
Chestnut Street, Philadelphia, Pennsylvania 19107-3496, is counsel to Master
Tax-Exempt Fund and will pass upon the legality of the Shares offered by the
Prospectus.



                    ADDITIONAL INFORMATION CONCERNING TAXES
                    ---------------------------------------

Federal
-------

          The following supplements the tax information contained in the
Prospectus.

          The Fund is treated as a separate corporate entity under the Internal
Revenue Code of 1986, as amended (the "Code"), and has qualified and intends to
continue to qualify as a regulated investment company.  If, for any reason, the
Fund does not qualify for a taxable year for the special Federal tax treatment
afforded regulated investment companies, the Fund would be subject to Federal
tax on all of its taxable income at regular corporate rates, without any
deduction for distributions to

                                     -37-
<PAGE>
 
shareholders.  In such event, dividend distributions would be taxable as
ordinary income to shareholders to the extent of the Fund's current and
accumulated earnings and profits and would be eligible for the dividends
received deduction in the case of corporate shareholders.

          As stated in the Prospectus, the Fund is not intended to constitute a
balanced investment program and is not designed for investors seeking capital
appreciation or maximum tax-exempt income irrespective of fluctuations in
principal.  Shares of the Fund will not be suitable for tax-exempt institutions
and may not be suitable for retirement plans qualified under Section 401 of the
Code, H.R. 10 plans and individual retirement accounts because such plans and
accounts are generally tax-exempt and, therefore, not only would not gain any
additional benefit from the Fund's dividends being tax-exempt, but such
dividends would be ultimately taxable to the beneficiaries when distributed to
them.  In addition, the Fund may not be an appropriate investment for entities
which are "substantial users" of facilities financed by private activity bonds
or "related persons" thereof.  "Substantial user" is defined under the Treasury
Regulations to include a non-exempt person who regularly uses a part of such
facilities in his trade or business and whose gross revenues derived with
respect to the facilities financed by the issuance of bonds are more than 5% of
the total revenues derived by all users of such facilities, who occupies more
than 5% of the usable area of such facilities or for whom such facilities or a
part thereof were specifically constructed, reconstructed or acquired.  "Related
persons" include certain related natural persons, affiliated corporations, a
partnership and its partners and an S Corporation and its shareholders.

          In order for the Fund to pay exempt-interest dividends for any taxable
year, at least 50% of the aggregate value of the Fund's portfolio must consist
of exempt-interest obligations at the close of each quarter of its taxable year.
Within 60 days after the close of the taxable year, the Fund will notify its
shareholders of the portion of the dividends paid by the Fund which constitutes
an exempt-interest dividend with respect to such taxable year.  However, the
aggregate amount of dividends so designated by the Fund cannot exceed the excess
of the amount of interest exempt from tax under Section 103 of the Code received
by the Fund during the taxable year over any amounts disallowed as deductions
under Sections 265 and 171(a)(2) of the Code.  The percentage of total dividends
paid by the Fund with respect to any taxable year which qualifies as exempt-
interest dividends will be the same for all shareholders receiving dividends
from the Fund for such year.

          A percentage of the interest on indebtedness incurred by a shareholder
to purchase or carry the Shares, equal to the percentage of the total non-
capital gain dividends distributed

                                     -38-
<PAGE>
 
during the shareholder's taxable year that is exempt-interest dividends, is not
deductible for income tax purposes.  In addition, if a shareholder holds Shares
for six months or less, any loss on the sale or exchange of those Shares will be
disallowed to the extent of the amount of exempt-interest dividends received
with respect to the Shares.  The Treasury Department, however, is authorized to
issue regulations reducing the six-month holding requirement to a period of not
less than the greater of 31 days or the period between regular dividend
distributions where the investment company regularly distributes at least 90% of
its net tax-exempt interest.  No such regulations had been issued as of the date
of this Statement of Additional Information.

          Any net long-term capital gains realized by the Fund will be
distributed at least annually.  The Fund will generally have no tax liability
with respect to such gains and the distributions will be taxable to shareholders
as long-term capital gains, regardless of how long a shareholder has held
Shares.  Such distributions will be designated as a capital gain dividend in a
written notice mailed by the Fund to shareholders not later than 60 days after
the close of the Fund's taxable year.


          A 4% non-deductible excise tax is imposed on regulated investment
companies that fail to currently distribute an amount equal to specified
percentages of their ordinary taxable income and capital gain net income (excess
of capital gains over capital losses).  The Fund intends to make sufficient
distributions or deemed distributions of its ordinary taxable income and any
capital gain net income prior to the end of each calendar year to avoid
liability for this excise tax.

          The Fund will be required in certain cases to withhold and remit to
the U.S. Treasury 31% of taxable dividends or 31% of gross proceeds realized
upon sale paid to shareholders who have failed to provide a correct tax
identification number in the manner required, who are subject to withholding by
the Internal Revenue Service for failure properly to include on their return
payments of taxable interest or dividends, or who have failed to certify to the
Fund when required to do so either that they are not subject to backup
withholding or that they are "exempt recipients."

Taxation of Certain Financial Instruments
-----------------------------------------

          Generally, futures contracts held by the Fund at the close of the
Fund's taxable year will be treated for Federal income tax purposes as sold for
their fair market value on the last business day of such year, a process known
as "marking-to-market." Forty percent of any gain or loss resulting from such
constructive sale will be treated as short-term capital gain or loss and 60% of
such gain or loss will be treated as long-term capital gain or loss, without
regard to the length of time the Fund has held the futures contract (the "40%-
60% rule"). The amount of any capital gain or loss actually realized by the Fund
in a subsequent sale or other disposition of those futures contracts will be
adjusted to reflect any capital gain or loss taken into account by the Fund in a
prior year as a result of the constructive sale of the contracts. With respect
to futures contracts to sell, which will be regarded as parts of a "mixed
straddle" because their values fluctuate inversely to the values of specific
securities held by the Fund, losses as to such contracts to sell will be subject
to certain loss deferral rules which limit the amount of loss currently
deductible on either part of the straddle to the amount thereof which exceeds
the unrecognized gain (if any) with respect to the other part of the straddle,
and to certain wash sales regulations. Under short sales rules, which will also
be applicable, the holding period of the securities forming part of the straddle
will (if they have not been held for the long-term holding period) be deemed not
to begin prior to termination of the straddle. With respect to certain futures
contracts, deductions for interest and carrying charges will not be allowed.
Notwithstanding the rules described above, with respect to futures contracts to
sell which are properly identified as such, the Fund may make an election which
will exempt (in whole or in part) those identified futures contracts from being
treated for Federal income tax purposes as sold on the last business day of the
Fund's taxable year, but gains and losses will be subject to such short sales,
wash sales, and loss deferral rules and the requirement to capitalize interest
and carrying charges. Under temporary regulations, the Fund would be allowed (in
lieu of the foregoing) to elect either (1) to offset gains or losses from
positions which are part of a mixed straddle by separately identifying each
mixed straddle to which such treatment applies, or (2) to establish a mixed
straddle account for which gains and losses would be recognized and offset on a
periodic basis during the taxable year. Under either election, the 40%-60% rule
will apply to the net gain or loss attributable to the futures contracts, but in
the case of a mixed straddle account election, not more than 50 percent of any
net gain may be treated as long-term and no more than 40 percent of any net loss
may be treated as short-term. Options on futures contracts generally receive
Federal tax treatment similar to that described above.

                                     -40-
<PAGE>
 
          The Fund will not be treated as a regulated investment company under
the Code if 30% or more of the Fund's gross income for a taxable year is derived
from gains realized on the sale or other disposition of the following
investments held for less than three months (the "30% test"):  (1) stock and
securities (as defined in section 2(a)(36) of the 1940 Act); (2) options,
futures and forward contracts other than those on foreign currencies; and (3)
foreign currencies (and options, futures and forward contracts on foreign
currencies) that are not directly related to the Fund's principal business of
investing in stock and securities (and options and futures with respect to
stocks and securities).  Interest (including original issue discount and accrued
market discount) received by the Fund upon maturity or disposition of a security
held for less than three months will not be treated as gross income derived from
the sale or other disposition of such security within the meaning of this
requirement.  However, any other income which is attributable to realized market
appreciation will be treated as gross income from the sale or other disposition
of securities for this purpose.  With respect to futures contracts, forward
contracts, options on futures contracts, and other financial instruments subject
to the marking-to-market rules described above, the Internal Revenue Service has
ruled in private letter rulings that a gain realized from such a contract,
option, or financial instrument will be treated as being derived from a security
held for three months or more (regardless of the actual period for which the
contract, option or instrument is held) if the gain arises as a result of a
constructive sale under the marking-to-market rules, and will be treated as
being derived from a security held for less than three months only if the
contract, option or instrument is terminated (or transferred) during the taxable
year (other than by reason of marking-to-market) and less than three months have
elapsed between the date the contract, option or instrument is acquired and the
termination date.  Increases and decreases in the value of the Fund's futures
contracts and other investments that qualify as part of a "designated hedge," as
defined in Section 851(g) of the Code, may be netted for purposes of determining
whether the 30% test is met.

                            *          *          *

          The foregoing discussion is based on Federal tax laws and regulations
which are in effect on the date of this Statement of Additional Information;
such laws and regulations may be changed by legislative or administrative
action.  Shareholders are advised to consult their tax advisers concerning their
specific situations and the application of state and local taxes.

                       PERFORMANCE AND YIELD INFORMATION
                       ---------------------------------

          The Fund may advertise the standardized effective 30-day (or one
month) yields calculated in accordance with the method prescribed by the SEC for
mutual funds.  Such yield will be calculated separately for each Fund according
to the following formula:

                                a-b                           
                   Yield = 2 [(----- + 1)/6/ - 1]              
                                 cd                            

     Where:    a =  dividends and interest earned during the period.

          b =  expenses accrued for the period (net of reimbursements).

          c =  average daily number of Shares outstanding that were entitled to
               receive dividends.

          d =  maximum offering price per Share on the last day of the period.

          For the purpose of determining interest earned during the period
(variable "a" in the formula), the Fund computes the yield to maturity of any
debt obligation held by it based on the market value of the obligation
(including actual accrued interest) at the close of business on the last
business day of each month, or, with respect to obligations purchased during the
month, the purchase price (plus actual accrued interest).  Such yield is then
divided by 360, and the quotient is multiplied by the market value of the
obligation (including actual accrued interest) in order to determine the
interest income on the obligation for each day of the subsequent month that the
obligation is in the portfolio.  It is assumed in the above calculation that
each month contains 30 days.  Also, the maturity of a debt obligation with a
call provision is deemed to be the next call date on which the obligation
reasonably may be expected to be called or, if none, the maturity date.  The
Fund calculates interest gained on tax-exempt obligations issued without
original issue discount and having a current market discount by using the coupon
rate of interest instead of the yield to maturity.  In the case of tax-exempt
obligations with original issue discount, where the discount based on the
current market value exceeds the then-remaining portion of original issue
discount, the yield to maturity is the imputed rate based on the original issue
discount calculation.  Conversely, where the discount based on the current
market value is less than the remaining portion of the original issue discount,
the yield to maturity is based on the market value.

                                     -42-
<PAGE>
 
          Expenses accrued for the period (variable "b" in the formula) include
all recurring fees charged by the Fund to all shareholder accounts and to the
particular series of Shares in proportion to the length of the base period and
the Fund's mean (or median) account size.  Undeclared earned income will be
subtracted from the maximum offering price per Share (variable "d" in the
formula).  The Fund's maximum offering price per Share for purposes of the
formula will include the maximum sales load imposed by the Fund -- currently
4.50% of the per share offering price.  Based on the foregoing calculations, the
Fund's standardized effective yield for the 30-day period ended March 31, 1995
was 4.14%.

          The "tax-equivalent" yield of the Fund is computed by: (a) dividing
the portion of the yield (calculated as above) that is exempt from Federal
income tax by one minus a stated Federal income tax rate and (b) adding that
figure to that portion, if any, of the yield that is not exempt from Federal
income tax.  Tax-equivalent yields assume the payment of Federal income taxes at
a rate of 31%.

          Based on the foregoing calculation, the tax-equivalent yield of the
Fund for the 30-day period ended March 31, 1995 was 6.00%.

          The Fund's "average annual total return" is computed by determining
the average annual compounded rate of return during specified periods that
equates the initial amount invested to the ending redeemable value of such
investment according to the following formula:

                      ERV  /1/n/
               T = [(-----) - 1]
                       P

     Where:    T =  average annual total return.

          ERV =     ending redeemable value of a hypothetical $1,000 payment
                    made at the beginning of the 1, 5 or 10 year (or other)
                    periods at the end of the applicable  period (or a
                    fractional portion thereof).

          P =  hypothetical initial payment of $1,000.

          n =  period covered by the computation, expressed in years.

          The calculation is made assuming that (1) all dividends and capital
gain distributions are reinvested on the reinvestment dates at the price per
Share existing on the reinvestment date

                                     -43-
<PAGE>
 
(reflecting any sales load charged upon such reinvestment), (2) all recurring
fees charged to all shareholder accounts are included, and (3) for any account
fees that vary with the size of the account, a mean (or median) account size in
the Fund during the periods is reflected.  The ending redeemable value (variable
"ERV" in the formula) is determined by assuming complete redemption of the
hypothetical investment after deduction of all nonrecurring charges at the end
of the measuring period.  In addition, the Fund's average annual total return
and aggregate total return quotations will reflect the deduction of the maximum
sales load charged in connection with the purchase of Shares.  The Fund's
average annual total return for Shares for the period from commencement of
operations (May 31, 1990) to March 31, 1995 and for the one year period ended
March 31, 1995 were 5.60% and 1.35%, respectively.

          The Fund may also from time to time include in advertisements, sales
literature and communications to shareholders a total return figure that is not
calculated according to the formula set forth above in order to compare more
accurately the Fund's performance with other measures of investment return.  For
example, in comparing the Fund's total return with data published by Lipper
Analytical Services, Inc., CDA Investment Technologies, Inc. or Weisenberger
Investment Company Service, or with the performance of an index, the Fund may
calculate its aggregate total return for the period of time specified in the
advertisement or communication by assuming the investment of $10,000 in Shares
and assuming the reinvestment of each dividend or other distribution at net
asset value on the reinvestment date.  Percentage increases are determined by
subtracting the initial value of the investment from the ending value and by
dividing the remainder by the beginning value.  The Fund does not, for these
purposes, deduct from the initial value invested any amount representing sales
charges.  The Fund will, however, disclose the maximum sales charge and will
also disclose that the performance data does not reflect sales charges and that
inclusion of sale charges would reduce the performance quoted.

          The total return and yield of the Fund may be compared to those of
other mutual funds with similar investment objectives and to other relevant
indices or to ratings prepared by independent services or other financial or
industry publications that monitor the performance of mutual funds.  For
example, the total return and/or yield of the Fund may be compared to data
prepared by Lipper Analytical Services, Inc., CDA Investment Technologies, Inc.
and Weisenberger Investment Company Service.  Total return and yield data as
reported in national financial publications such as Money Magazine, Forbes,
                                                    ----- --------  ------ 
Barron's, The Wall Street Journal and The New York Times, or in publications of
--------  --- ---- ------ -------     --- --- ---- -----                       
a local or regional nature, may also be used in comparing the performance of the
Fund.  Advertisements, sales literature or reports to shareholders may from time
to time also include a

                                     -44-
<PAGE>
 
discussion and analysis of the Fund's performance, including without limitation,
those factors, strategies and technologies that together with market conditions
and events, materially affected the Fund's performance.

          The Fund may also from time to time include discussions or
illustrations of the effects of compounding in advertisements.  "Compounding"
refers to the fact that, if dividends or other distributions of the Fund
investment are reinvested by being paid in additional Fund shares, any future
income or capital appreciations of the Fund would increase the value, not only
of the original Fund investment, but also of the additional Fund shares received
through reinvestment.  As a result, the value of the Fund investment would
increase more quickly than if dividends or other distributions had been paid in
cash.  The Fund may also include discussions or illustrations of the potential
investment goals of a prospective investor, investment management techniques,
policies or investment suitability of the Fund, economic conditions, the effects
of inflation and historical performance of various asset classes, including but
not limited to, stocks, bonds and Treasury bills.  From time to time
advertisements, sales literature or communications to shareholders may summarize
the substance of information contained in shareholder reports (including the
investment composition of the Fund), as well as the views of the Investment
Adviser as to current market, economy, trade and interest rate trends,
legislative, regulatory and monetary developments, investment strategies and
related matters believed to be of relevance to the Fund.  The Fund may also
include in advertisements charts, graphs or drawings which illustrate the
potential risks and rewards of investment in various investment vehicles,
including but not limited to, stocks, bonds, treasury bills and shares of the
Fund.  In addition, advertisement, sales literature or shareholder
communications may include a discussion of certain attributes or benefits to be
derived by an investment in the Fund.  Such advertisements or communicators may
include symbols, headlines or other material which highlight or summarize the
information discussed in more detail therein.


                                 MISCELLANEOUS
                                 -------------

          As used in the Prospectus, "assets belonging to the Fund" means the
consideration received upon the issuance of Shares in the Fund, together with
all income, earnings, profits, and proceeds derived from the investment thereof,
including any proceeds from the sale of such investments, any funds or payments
derived from any reinvestment of such proceeds, and a portion of any general
assets of Master Tax-Exempt Fund not belonging to a particular portfolio of
Master Tax-Exempt Fund. In determining the net asset value of the Fund's Shares,
assets belonging to the Fund allocable to Shares are charged with the

                                     -45-
<PAGE>
 
direct liabilities of the Fund allocable to Shares and with a share of the
general liabilities of Master Tax-Exempt Fund which are normally allocated in
proportion to the relative asset values of Master Tax-Exempt Fund's portfolios
at the time of allocation.  Subject to the provisions of Master Tax-Exempt
Fund's Charter, determinations by the Board of Directors as to the direct and
allocable liabilities, and the allocable portion of any general assets with
respect to the Fund, are conclusive.

          As of July 11, 1995, U.S. Trust held of record substantially all of
the outstanding Shares of the Fund as agent or custodian for its customers, but
did not own such Shares beneficially because it did not have discretion to vote
or invest such Shares.

Commercial Paper Ratings
------------------------

          A Standard & Poor's commercial paper rating is a current assessment of
the likelihood of timely payment of debt considered short-term in the relevant
market.  The following summarizes the rating categories used by Standard and
Poor's for commercial paper:

          "A-1" - Issue's degree of safety regarding timely payment is strong.
Those issues determined to possess extremely strong safety characteristics are
denoted "A-1+."

          "A-2" - Issue's capacity for timely payment is satisfactory.  However,
the relative degree of safety is not as high as for issues designated "A-1."

          "A-3" - Issue has an adequate capacity for timely payment.  It is,
however, somewhat more vulnerable to the adverse effects of changes and
circumstances than an obligation carrying a higher designation.

          "B" - Issue has only a speculative capacity for timely payment.

          "C" - Issue has a doubtful capacity for payment.

          "D" - Issue is in payment default.


          Moody's commercial paper ratings are opinions of the ability of
issuers to repay punctually promissory obligations not having an original
maturity in excess of 9 months.  The following summarizes the rating categories
used by Moody's for commercial paper:

          "Prime-1" - Issuer or related supporting institutions are considered
to have a superior capacity for repayment of short-term promissory obligations.
Prime-1 repayment capacity will normally be evidenced by the following
characteristics: leading market positions in well established industries; high
rates of return on funds employed; conservative capitalization structures with
moderate reliance on debt and ample asset protection; broad margins in earning
coverage of fixed financial charges and high internal cash generation; and well
established access to a range of financial markets and assured sources of
alternate liquidity.

                                      A-1
<PAGE>
 
          "Prime-2" - Issuer 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 cited above 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.

          "Prime-3" - Issuer or related supporting institutions have an
acceptable capacity for repayment of short-term promissory obligations.  The
effects of industry characteristics and market composition may be more
pronounced.  Variability in earnings and profitability may result in changes in
the level of debt protection measurements and the requirement for relatively
high financial leverage.  Adequate alternate liquidity is maintained.

          "Not Prime" - Issuer does not fall within any of the Prime rating
categories.


          The three rating categories of Duff & Phelps for investment grade
commercial paper and short-term debt are "D-1," "D-2" and "D-3."  Duff & Phelps
employs three designations, "D-1+," "D-1" and "D-1-," within the highest rating
category.  The following summarizes the rating categories used by Duff & Phelps
for commercial paper:

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

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

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

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

          "D-3" - Debt possesses satisfactory liquidity, and other protection
factors qualify issue as investment grade.  Risk

                                      A-2
<PAGE>
 
factors are larger and subject to more variation.  Nevertheless, timely payment
is expected.

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

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


          Fitch short-term ratings apply to debt obligations that are payable on
demand or have original maturities of up to three years.  The following
summarizes the rating categories used by Fitch for short-term obligations:

          "F-1+" - Securities possess exceptionally strong credit quality.
Issues assigned this rating are regarded as having the strongest degree of
assurance for timely payment.

          "F-1" - Securities possess very strong credit quality.  Issues
assigned this rating reflect an assurance of timely payment only slightly less
in degree than issues rated "F-1+."

          "F-2" - Securities possess good credit quality.  Issues assigned this
rating have a satisfactory degree of assurance for timely payment, but the
margin of safety is not as great as the "F-1+" and "F-1" categories.

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

          "F-S" - Securities possess weak credit quality.  Issues assigned this
rating have characteristics suggesting a minimal degree of assurance for timely
payment and are vulnerable to near-term adverse changes in financial and
economic conditions.

          "D" - Securities are in actual or imminent payment default.

          Fitch may also use the symbol "LOC" with its short-term ratings to
indicate that the rating is based upon a letter of credit issued by a commercial
bank.

          Thomson BankWatch short-term ratings assess the likelihood of an
untimely or incomplete payment of principal or interest of unsubordinated
instruments having a maturity of one

                                      A-3
<PAGE>
 
year or less which is issued by United States commercial banks, thrifts and non-
bank banks; non-United States banks; and broker-dealers.  The following
summarizes the ratings used by Thomson BankWatch:

          "TBW-1" - This designation represents Thomson BankWatch's highest
rating category and indicates a very high degree of likelihood that principal
and interest will be paid on a timely basis.

          "TBW-2" - This designation indicates that while the degree of safety
regarding timely payment of principal and interest is strong, the relative
degree of safety is not as high as for issues rated "TBW-1."

          "TBW-3" - This designation represents the lowest investment grade
category and indicates that while the debt is more susceptible to adverse
developments (both internal and external) than obligations with higher ratings,
capacity to service principal and interest in a timely fashion is considered
adequate.

          "TBW-4" - This designation indicates that the debt is regarded as non-
investment grade and therefore speculative.


          IBCA assesses the investment quality of unsecured debt with an
original maturity of less than one year which is issued by bank holding
companies and their principal bank subsidiaries.  The following summarizes the
rating categories used by IBCA for short-term debt ratings:

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

          "A2" - Obligations are supported by a good capacity for timely
repayment.

          "A3" - Obligations are supported by a satisfactory capacity for timely
repayment.

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

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

                                      A-4

Corporate and Municipal Long-Term Debt Ratings
----------------------------------------------

          The following summarizes the ratings used by Standard & Poor's for
corporate and municipal debt:

          "AAA" - This designation represents the highest rating assigned by
Standard & Poor's to a debt obligation and indicates an extremely strong
capacity to pay interest and repay principal.

          "AA" - Debt is considered to have a very strong capacity to pay
interest and repay principal and differs from AAA issues only in small degree.

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

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

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

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

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

                                      A-5
<PAGE>
 
          "CCC" - Debt has a currently identifiable vulnerability to default,
and is dependent upon favorable business, financial and economic conditions to
meet timely payment of interest and repayment of principal.  In the event of
adverse business, financial or economic conditions, it is not likely to have the
capacity to pay interest and repay principal.  The "CCC" rating category is also
used for debt subordinated to senior debt that is assigned an actual or implied
"B" or "B-" rating.

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

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

          "CI" - This rating is reserved for income bonds on which no interest
is being paid.

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

          PLUS (+) OR MINUS (-) - The ratings from "AA" through "CCC" may be
modified by the addition of a plus or minus sign to show relative standing
within the major rating categories.

          "r" - This rating is attached to highlight derivative, hybrid, and
certain other obligations that S & P believes may experience high volatility or
high variability in expected returns due to non-credit risks.  Examples of such
obligations are: securities whose principal or interest return is indexed to
equities, commodities, or currencies; certain swaps and options; and interest
only and principal only mortgage securities.

     The following summarizes the ratings used by Moody's for corporate and
municipal long-term debt:

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

                                      A-6
<PAGE>
 
          "Aa" - Bonds are judged to be of high quality by all standards.
Together with the "Aaa" group they comprise what are generally known as high
grade bonds.  They are rated lower than the best bonds because margins of
protection may not be as large as in "Aaa" securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risks appear somewhat larger than in "Aaa"
securities.

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

          "Baa" - Bonds considered medium-grade obligations, i.e., they are
neither highly protected nor poorly secured.  Interest payments and principal
security appear adequate for the present but certain protective elements may be
lacking or may be characteristically unreliable over any great length of time.
Such bonds lack outstanding investment characteristics and in fact have
speculative characteristics as well.

          "Ba," "B," "Caa," "Ca," and "C" - Bonds that possess one of these
ratings provide questionable protection of interest and principal ("Ba"
indicates some speculative elements; "B" indicates a general lack of
characteristics of desirable investment; "Caa" represents a poor standing; "Ca"
represents obligations which are speculative in a high degree; and "C"
represents the lowest rated class of bonds). "Caa," "Ca" and "C" bonds may be in
default.

          Con. (---) - Bonds for which the security depends upon the completion
of some act or the fulfillment of some condition are rated conditionally.  These
are bonds secured by (a) earnings of projects under construction, (b) earnings
of projects unseasoned in operation experience, (c) rentals which begin when
facilities are completed, or (d) payments to which some other limiting condition
attaches.  Parenthetical rating denotes probable credit stature upon completion
of construction or elimination of basis of condition.

          Moody's applies numerical modifiers 1, 2 and 3 in each generic
classification from "Aa" to "B" in its bond rating system.  The modifier 1
indicates that the issuer 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 issuer ranks at the lower end of its generic rating category.

                                      A-7
<PAGE>
 
          The following summarizes the long-term debt ratings used by Duff &
Phelps for corporate and municipal long-term debt:

          "AAA" - Debt is considered to be of the highest credit quality.  The
risk factors are negligible, being only slightly more than for risk-free U.S.
Treasury debt.

          "AA" - Debt is considered of high credit quality.  Protection factors
are strong.  Risk is modest but may vary slightly from time to time because of
economic conditions.

          "A" - Debt possesses protection factors which are average but
adequate.  However, risk factors are more variable and greater in periods of
economic stress.

          "BBB" - Debt possesses below average protection factors but such
protection factors are still considered sufficient for prudent investment.
Considerable variability in risk is present during economic cycles.

          "BB," "B," "CCC," "DD," and "DP" - Debt that possesses one of these
ratings is considered to be below investment grade.  Although below investment
grade, debt rated "BB" is deemed likely to meet obligations when due.  Debt
rated "B" possesses the risk that obligations will not be met when due.  Debt
rated "CCC" is well below investment grade and has considerable uncertainty as
to timely payment of principal, interest or preferred dividends.  Debt rated
"DD" is a defaulted debt obligation, and the rating "DP" represents preferred
stock with dividend arrearages.

          To provide more detailed indications of credit quality, the "AA," "A,"
"BBB," "BB" and "B" ratings may be modified by the addition of a plus (+) or
minus (-) sign to show relative standing within these major categories.


          The following summarizes the highest four ratings used by Fitch for
corporate and municipal bonds:

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

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

                                      A-8
<PAGE>
 
          "A" - Bonds considered to be investment grade and of high credit
quality.  The obligor's ability to pay interest and repay principal is
considered to be strong, but may be more vulnerable to adverse changes in
economic conditions and circumstances than bonds with higher ratings.

          "BBB" - Bonds considered to be investment grade and of satisfactory
credit quality.  The obligor's ability to pay interest and repay principal is
considered to be adequate.  Adverse changes in economic conditions and
circumstances, however, are more likely to have an adverse impact on these
bonds, and therefore, impair timely payment.  The likelihood that the ratings of
these bonds will fall below investment grade is higher than for bonds with
higher ratings.

          "BB," "B," "CCC," "CC," "C," "DDD," "DD," and "D" -Bonds that possess
one of these ratings are considered by Fitch to be speculative investments.  The
ratings "BB" to "C" represent Fitch's assessment of the likelihood of timely
payment of principal and interest in accordance with the terms of obligation for
bond issues not in default.  For defaulted bonds, the rating "DDD" to "D" is an
assessment of the ultimate recovery value through reorganization or liquidation.

          To provide more detailed indications of credit quality, the Fitch
ratings from and including "AA" to "C" may be modified by the addition of a plus
(+) or minus (-) sign to show relative standing within these major rating
categories.


          IBCA assesses the investment quality of unsecured debt with an
original maturity of more than one year which is issued by bank holding
companies and their principal bank subsidiaries.  The following summarizes the
rating categories used by IBCA for long-term debt ratings:

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

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

          "A" - Obligations for which there is a low expectation of investment
risk.  Capacity for timely repayment of principal and interest is strong,
although adverse changes in business,

                                      A-9
<PAGE>
 
economic or financial conditions may lead to increased investment risk.

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

          "BB," "B," "CCC," "CC," and "C" - Obligations are assigned one of
these ratings where it is considered that speculative characteristics are
present.  "BB" represents the lowest degree of speculation and indicates a
possibility of investment risk developing.  "C" represents the highest degree of
speculation and indicates that the obligations are currently in default.

          IBCA may append a rating of plus (+) or minus (-) to a rating to
denote relative status within major rating categories.


          Thomson BankWatch assesses the likelihood of an untimely repayment of
principal or interest over the term to maturity of long term debt and preferred
stock which are issued by United States commercial banks, thrifts and non-bank
banks; non-United States banks; and broker-dealers.  The following summarizes
the rating categories used by Thomson BankWatch for long-term debt ratings:

          "AAA" - This designation represents the highest category assigned by
Thomson BankWatch to long-term debt and indicates that the ability to repay
principal and interest on a timely basis is very high.

          "AA" - This designation indicates a superior ability to repay
principal and interest on a timely basis with limited incremental risk versus
issues rated in the highest category.

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

          "BBB" - This designation represents Thomson BankWatch's lowest
investment grade category and indicates an acceptable capacity to repay
principal and interest.  Issues rated "BBB" are, however, more vulnerable to
adverse developments (both internal and external) than obligations with higher
ratings.

          "BB," "B," "CCC," and "CC," - These designations are assigned by
Thomson BankWatch to non-investment grade long-term

                                     A-10
<PAGE>
 
debt.  Such issues are regarded as having speculative characteristics regarding
the likelihood of timely payment of principal and interest.  "BB" indicates the
lowest degree of speculation and "CC" the highest degree of speculation.

          "D" - This designation indicates that the long-term debt is in
default.

          PLUS (+) OR MINUS (-) - The ratings from "AAA" through "CC" may
include a plus or minus sign designation which indicates where within the
respective category the issue is placed.


Municipal Note Ratings
----------------------

          A Standard and Poor's rating reflects the liquidity concerns and
market access risks unique to notes due in three years or less.  The following
summarizes the ratings used by Standard & Poor's Ratings Group for municipal
notes:

          "SP-1" - The issuers of these municipal notes exhibit very strong or
strong capacity to pay principal and interest.  Those issues determined to
possess overwhelming safety characteristics are given a plus (+) designation.

          "SP-2" - The issuers of these municipal notes exhibit satisfactory
capacity to pay principal and interest.

          "SP-3" - The issuers of these municipal notes exhibit speculative
capacity to pay principal and interest.

 
          Moody's ratings for state and municipal notes and other short-term
loans are designated Moody's Investment Grade ("MIG") and variable rate demand
obligations are designated Variable Moody's Investment Grade ("VMIG").  Such
ratings recognize the differences between short-term credit risk and long-term
risk.  The following summarizes the ratings by Moody's Investors Service, Inc.
for short-term notes:

          "MIG-1"/"VMIG-1" - Loans bearing this designation are of the best
quality, enjoying strong protection by established cash flows, superior
liquidity support or demonstrated broad-based access to the market for
refinancing.

          "MIG-2"/"VMIG-2" - Loans bearing this designation are of high quality,
with margins of protection ample although not so large as in the preceding
group.

          "MIG-3"/"VMIG-3" - Loans bearing this designation are of favorable
quality, with all security elements accounted for but lacking the undeniable
strength of the preceding grades.

                                     A-11
<PAGE>
 
Liquidity and cash flow protection may be narrow and market access for
refinancing is likely to be less well established.

          "MIG-4"/"VMIG-4" - Loans bearing this designation are of adequate
quality, carrying specific risk but having protection commonly regarded as
required of an investment security and not distinctly or predominantly
speculative.

          "SG" - Loans bearing this designation are of speculative quality and
lack margins of protection.


          Fitch and Duff & Phelps use the short-term ratings described under
Commercial Paper Ratings for municipal notes.
