MAS Funds (the Fund) is a no-load mutual fund consisting of twenty-five
portfolios, twenty-three of which are described in this Prospectus. Each
portfolio in this Prospectus operates as a separate diversified investment
company except the Global Fixed Income, International Fixed Income, and Emerging
Markets Portfolios which are non-diversified investment companies. The
investment objective of each portfolio is described with a summary of investment
policies as referenced below. The Fund's Small Cap Value Portfolio is not
currently being offered to new investors. This Prospectus offers the
Institutional Class Shares of the Fund. The Fund also offers Adviser Class
Shares and Investment Class Shares.
- -------------------------------------------------------------------------------
- -------------------------------------------------------------------------------
Shares of the Cash Reserves Portfolios are neither insured nor guaranteed by the
U.S. Government. The Portfolio seeks to maintain, but there can be no assurance
that it will be able to maintain, a constant net asset value of $1.00 per share.
- -------------------------------------------------------------------------------
The High Yield Portfolio will invest primarily, and certain other portfolios of
the Fund may invest to varying degrees, in high yield, high risk securities
which are speculative with regard to payment of interest and return of principal
(commonly referred to as junk bonds); therefore, investments in these portfolios
may not be suitable for all investors. See High Yield Investing in the Glossary
of Strategies for additional information regarding certain risks associated with
investment in such securities.

* Where applicable as described in Financial Highlights, the Total Operating 
  Expense ratios reflected in the table above are higher than the ratio of 
  expenses actually deducted from portfolio assets because of the effect of 
  expense offset arrangements. The result of such arrangements is to offset 
  expense that otherwise would be deducted from portolio assets. Until 
  further notice, the Adviser has voluntarily agreed to waive its advisory 
  fees and reimburse certain expenses to the extent necessary to keep Total 
  Operating Expenses actually deducted from portfolio assets for the Emerging 
  Markets, Mid Cap Value, Cash Reserves, Domestic Fixed Income, Intermediate 
  Duration, Limited Duration, Mortgage- Backed Securities, Municipal, PA 
  Municipal and Multi-Asset-Class Portfolios from exceeding 1.18%, 0.88%, 
  0.32%, 0.50%, 0.52%, 0.42%, 0.50%, 0.50%, 0.50% and 0.58%, respectively. 
  Absent fee waivers and reimbursements by the Adviser, Total Operating 
  Expenses would be 1.470%, 3.060%, 0.436%, 0.602%, 0.600%, 0.449%, 0.510%, 
  0.590%, 0.690% and 0.724%, for the Emerging Markets, Mid Cap Value, Cash 
  Reserves, Domestic Fixed Income, Intermediate Duration, Limited Duration, 
  Mortgage-Backed Securities, Municipal, PA Municipal and Multi-Asset-Class 
  Portfolios, respectively.

EXAMPLE 

The purpose of this table is to assist in understanding the various expenses 
that a shareholder in a portfolio will bear directly or indirectly. The 
following example illustrates the expenses that an investor would pay on a 
$1,000 investment over various time periods assuming (1) a 5% annual rate of 
return, and (2) redemption at the end of each time period. The example should 
not be considered a representation of past or future expenses and actual 
expenses may be greater or less than those shown. For portfolios with less 
than 10 months of operations, only the 1 and 3 year examples are shown.

porates, Mortgage Securities, Foreign Bonds and other Fixed-Income Securities 
and Derivatives. The portfolio is structured to complement an investment in 
one or more of the Fund's Equity Portfolios for investors seeking a balanced 
investment. The portfolio's average weighted maturity will ordinarily exceed 
five years. 

BALANCED INVESTING 

Balanced Portfolio - seeks to achieve above-average total return over a 
market cycle of three to five years, consistent with reasonable risk, by 
investing in a diversified portfolio of Equity Securities, Fixed-Income 
Securities and Derivatives. When the Adviser judges the relative outlook for 
the equity and fixed-income markets to be neutral, the portfolio will be 
invested 60% in equity securities and 40% in fixed-income securities. The 
asset mix is actively managed by the Adviser, with equity securities 
ordinarily representing between 45% and 75% of the total investment. The 
average weighted maturity of the fixed-income portion of the portfolio will 
ordinarily be greater than five years. 


Multi-Asset-Class Portfolio - seeks to achieve above-average total return 
over a market cycle of three to five years, consistent with reasonable risk, 
by investing primarily in a diversified portfolio of Equity Securities, 
Fixed- Income Securities and High Yield Securities of United States and 
foreign issuers and Derivatives. The asset mix is actively managed by the 
Adviser. 


RISK FACTORS: Prospective investors in the Fund should consider the following 
factors as they apply to each Portfolio's allowable investments and policies. 
See the Prospectus Glossary for more information on terms printed in bold 
type: 

o  Each portfolio may invest in Repurchase Agreements, which entail a risk of 
   loss should the seller default in its obligation to repurchase the 
   security which is the subject of the transaction; 

o  Each portfolio may participate in a Securities Lending program which 
   entails a risk of loss should a borrower fail financially; 

o  Fixed-Income Securities will be affected by general changes in interest 
   rates resulting in increases or decreases in the value of the obligations 
   held by a portfolio. The value of fixed-income securities can be expected 
   to vary inversely to changes in prevailing interest rates, i.e., as 
   interest rates decline, market value tends to increase and vice versa; 

o  Investments in common stocks are subject to market risks which may cause 
   their prices to fluctuate over time. Changes in the value of portfolio 
   securities will not necessarily affect cash income derived from these 
   securities, but will affect a Portfolio's net asset value. 

o  Securities purchased on a When-Issued basis may decline or appreciate in 
   market value prior to their actual delivery to the portfolio; 


o  Each portfolio (except the Cash Reserves Portfolio) may invest in certain 
   instruments such as Forwards, certain types of Futures & Options, certain 
   types of Mortgage Securities and When-Issued Securities which require the 
   portfolio to segregate some or all of its cash or liquid securities to 
   cover its obligations pursuant to such instruments. As asset segregation 
   reaches certain levels, a portfolio may lose flexibility in managing its 
   investments properly, responding to shareholder redemption requests, or 
   meeting other obligations and may be forced to sell other securities that 
   it wanted to retain or to realize unintended gains or losses; 

o  Investments in floating rate securities (Floaters) and inverse floating 
   rate securities (Inverse Floaters) and mortgage-backed securities 
   (Mortgage Securities), including principal-only and interest-only Stripped 
   Mortgage-Backed Securities (SMBS), may be highly sensitive to interest 
   rate changes, and highly sensitive to the rate of principal payments 
   (including prepayments on underlying mortgage assets);

o  From time to time Congress has considered proposals to restrict or 
   eliminate the tax-exempt status of Municipals. If such proposals were 
   enacted in the future, the Municipal Portfolio and the PA Municipal 
   Portfolio would reconsider their investment objectives and policies; 

o  Investments in securities rated below investment grade, generally referred 
   to as High Yield, high risk or junk bonds, carry a high degree of credit 
   risk and are considered speculative by the major rating agencies; 

o  Investments in foreign securities involve certain special considerations 
   which are not typically associated with investing in U.S. companies. See 
   Foreign Investing. The portfolios investing in foreign securities may also 
   engage in foreign currency exchange transactions. See Forwards, Futures & 
   Options, and Swaps; and, 

o  The Emerging Markets, Global Fixed Income, and International Fixed Income 
   Portfolios are Non-Diversified for purposes of the Investment Company Act 
   of 1940, as amended, meaning that they may invest a greater percentage of 
   assets in the securities of one issuer than the other portfolios. 

HOW TO INVEST: Institutional Class Shares of each portfolio are available to 
clients of the Adviser with combined investments of $5,000,000 and 
Shareholder Organizations who have a contractual arrangement with the Fund, 
including institutions such as trusts, foundations or broker-dealers 
purchasing for the accounts of others. Shares are offered directly to 
investors without a sales commission at the net asset value of the portfolio 
next determined after receipt of the order. Share purchases may be made by 
sending investments directly to the Fund, subject to acceptance by the Fund. 
The Fund also offers Investment and Adviser Class Shares which differ from 
the Institutional Class Shares in expenses charged and purchase requirements. 
Further information relating to the other classes may be obtained by calling 
800-354-8185. 

HOW TO REDEEM: Shares of each portfolio may be redeemed at any time at the 
net asset value of the portfolio next determined after receipt of the 
redemption request. The redemption price may be more or less than the 
purchase price, except ordinarily in the case of the Cash Reserves Portfolio 
which seeks to maintain, but does not guarantee, a constant net asset value 
per share of $1.00. See Redemption of Shares and Shareholder Services.

++For the period indicated, the Adviser voluntarily agreed to waive its advisory
  fees and reimburse certain expenses to the extent necessary, if any, to keep

YIELD AND TOTAL RETURN: 

From time to time each portfolio of the Fund advertises its yield and total 
return. Both yield and total return figures are based on historical earnings 
and are not intended to indicate future performance. The average annual total 
return reflects changes in the price of a portfolio's shares and assumes that 
any income dividends and/or capital gain distributions made by the portfolio 
during the period were reinvested in additional shares of the portfolio. 
Figures will be given for one-, five- and ten-year periods ending with the 
most recent calendar quarter-end (if applicable), and may be given for other 
periods as well (such as from commencement of the portfolio's operations). 
When considering average total return figures for periods longer than one 
year, it is important to note that a portfolio's annual total return for any 
one year in the period might have been greater or less than the average for 
the entire period. 


In addition to average annual total return, a portfolio may also quote an 
aggregate total return for various periods representing the cumulative change 
in value of an investment in a portfolio for a specific period. Aggregate 
total returns may be shown by means of schedules, charts or graphs and may 
include subtotals of the various components of total return (e.g., income 
dividends or returns for specific types of securities such as industry or 
country types). 


The yield of a portfolio (other than the Cash Reserves Portfolio) is computed 
by dividing the net investment income per share (using the average number of 
shares entitled to receive dividends) earned during the 30-day period stated 
in the advertisement by the closing price per share on the last day of the 
period. For the purpose of determining net investment income, the calculation 
includes as expenses of the portfolio all recurring fees and any non 
recurring charges for the period stated. The yield formula provides for 
semiannual compounding, which assumes that net investment income is earned 
and reinvested at a constant rate and annualized at the end of a six-month 
period. Methods used to calculate advertised yields are standardized for all 
stock and bond mutual funds. However, these methods differ from the 
accounting methods used by the portfolio to maintain its books and records, 
therefore the advertised 30-day yield may not reflect the income paid to your 
own account or the yield reported in the portfolio's reports to shareholders. 
A portfolio may also advertise or quote a yield which is gross of expenses. 


The Municipal and PA Municipal Portfolios may also advertise or quote 
tax-equivalent yields and after-tax total returns. A tax-equivalent yield 
shows the level of taxable yield needed to produce an after-tax equivalent to 
the portfolio's tax-free yield. This is done by increasing the portfolio's 
yield (computed as above) by the amount necessary to reflect the payment of 
Federal income tax (and Pennsylvania income tax, in the case of the PA 
Municipal Portfolio) at a tax rate stated in the advertisement or quote. An 
after-tax return reflects the average annual or cumulative change in value 
over the measuring period after the deduction of taxes at rates stated in the 
advertisement or quote. 

From time to time the Cash Reserves Portfolio may advertise or quote its 
yield and effective yield. The yield of the Cash Reserves Portfolio refers to 
the income generated by an investment in the portfolio over a stated seven 
day period. This income is then annualized. That is, the amount of income 
generated by the investment during that week is assumed to be generated each 
week over a 52-week period and is shown as a percentage of the investment. 
The effective yield is calculated similarly, but the income earned over the 
seven day period by an investment in the portfolio is assumed to be 
reinvested when the return is annualized. The "effective yield" will be 
higher than the yield because of the compounding effect of this assumed 
reinvestment. 

The performance of a portfolio may be compared to data prepared by 
independent services which monitor the performance of investment companies, 
data reported in financial and industry publications, returns of other 
investment advisers and mutual funds, and various indices as further 
described in the Statement of Additional Information. 


The performance of Institutional Class Shares, Investment Class Shares and 
Adviser Class Shares differ because of any class specific expenses paid by 
each class and the shareholder servicing fees charged to Investment Class 
Shares and distribution fees charged to Adviser Class Shares.

The Annual Report to Shareholders of the Fund for the Fund's most recent 
fiscal year-end contains additional performance information that includes 
comparisons with appropriate indices. The Annual Report is available without 
charge upon request by writing to the Fund or calling the Client Services 
Group at the telephone number shown on the front cover of this Prospectus. 


GENERAL INFORMATION: 


The following information relates to each portfolio of the Fund and should be 
read in conjunction with the specific information about each portfolio. 


Objectives: Each portfolio seeks to achieve its investment objective relative 
to the universe of securities in which it is authorized to invest and, 
accordingly, the total return or current income achieved by a portfolio may 
not be as great as that achieved by another portfolio that can invest in a 
broader range of securities. Fixed-Income Portfolios will seek to produce 
total return by actively trading portfolio securities. The objective of each 
portfolio is fundamental and may only be changed with approval of holders of 
a majority of the shares of each portfolio. The achievement of any 
portfolio's objective cannot be assured. 

Suitability: The Fund's portfolios are designed for long-term investors who 
can accept the risks entailed in investing in the stock and bond markets, and 
are not meant to provide a vehicle for playing short-term swings in the 
market. The Fund's portfolios are designed principally for the investments of 
tax-exempt fiduciary investors who are entrusted with the responsibility of 
investing assets held for the benefit of others. Since such investors are not 
subject to Federal income taxes, securities transactions for all portfolios 
except the Municipal and PA Municipal Portfolios will not be influenced by 
the different tax treatment of long-term capital gains, short-term capital 
gains, and dividend income under the Internal Revenue Code. Investments in 
the Municipal and PA Municipal Portfolios are suitable for taxable investors 
who would benefit from the portfolios' tax-exempt income. 

Securities Lending: Each portfolio may lend its securities to qualified 
brokers, dealers, banks and other financial institutions for the purpose of 
realizing additional income. Loans of securities will be collateralized by 
cash, letters of credit, or securities issued or guaranteed by the U.S. 
Government or its agencies. The collateral will equal at least 100% of the 
current market value of the loaned securities. In addition, a portfolio will 
not loan its portfolio securities to the extent that greater than one-third 
of its total assets, at fair market value, would be committed to loans at 
that time. 

Illiquid Securities/Restricted Securities: Each of the portfolios may invest 
up to 15% of its net assets (except the Cash Reserves Portfolio, which may 
invest up to 10% of its net assets) in securities that are illiquid by virtue 
of the absence of a readily available market, or because of legal or 
contractual restrictions on resale. This policy does not limit the 
acquisition of (i) restricted securities eligible for resale to qualified 
institutional buyers pursuant to Rule 144A under the Securities Act of 1933 
or (ii) commercial paper issued pursuant to Section 4(2) under the Securities 
Act of 1933, that are determined to be liquid in accordance with guidelines 
established by the Fund's Board of Trustees. 

Turnover: The Adviser manages the portfolios generally without regard to 
restrictions on portfolio Turnover, except those imposed by provisions of the 
federal tax laws regarding short-term trading. In general, the portfolios 
will not trade for short-term profits, but when circumstances warrant, 
investments may be sold without regard to the length of time held. 

The larger than expected turnover rate for the Mid Cap Value Portfolio was 
due to the small size of the portfolio and the fact that it commenced 
operations during the fiscal year. In addition, the portfolio entered into 
various transactions which increased the turnover rate in order to qualify 
under certain tax rules. With respect to the Fixed Income Portfolios and the 
fixed-income portion of the Balanced Portfolio, the annual turnover rate will 
ordinarily exceed 100% due to changes in portfolio duration, yield curve 
strategy or commitments to forward delivery mortgage-backed securities. 
- -------------------------------------------------------------------------------
MAS Funds - 16       Terms in bold type are defined in the Prospectus Glossary
<PAGE>

Portfolio turnover rates for certain portfolios are as follows: International 
Equity - 112%, Mid Cap Growth - 129%, Mid Cap Value - 639%, Domestic Fixed 
Income - 313%, Fixed Income - 140%, Fixed Income II - 153%, Global Fixed 
Income - 118%, Intermediate Duration - 168%, International Fixed Income - 
140%, Limited Duration - 119%, Mortgage-Backed Securities - 107%, Special 
Purpose Fixed Income - 143% and Multi-Asset-Class - 112%. 

High rates of portfolio turnover necessarily result in correspondingly 
heavier brokerage and portfolio trading costs which are paid by a portfolio. 
Trading in Fixed-Income Securities does not generally involve the payment of 
brokerage commissions, but does involve indirect transaction costs. In 
addition to portfolio trading costs, higher rates of portfolio turnover may 
result in the realization of capital gains. To the extent net short-term 
capital gains are realized, any distributions resulting from such gains are 
considered ordinary income for federal income tax purposes. 

Cash Equivalents/Temporary Defensive Investing: Although each portfolio 
intends to remain substantially fully invested, a small percentage of a 
portfolio's assets are generally held in the form of Cash Equivalents in 
order to meet redemption requests and otherwise manage the daily affairs of 
each portfolio. In addition, any portfolio may, when the Adviser deems that 
market conditions are such that a temporary defensive approach is desirable, 
invest in cash equivalents or the Fixed-Income Securities listed for that 
portfolio without limit. In addition, the Adviser may, for temporary 
defensive purposes, increase or decrease the average weighted maturity or 
duration of any Fixed-Income portfolio without regard to that portfolio's 
usual average weighted maturity. 

Concentration: Concentration is defined as investment of 25% or more of a 
portfolio's total assets in the securities of issuers operating in any one 
industry. Except as provided in a portfolio's specific investment policies, a 
portfolio will not concentrate investments in any one industry. 

Investment Limitations: Each portfolio is subject to certain limitations 
designed to reduce its exposure to specific situations. Some of these 
limitations are: 

(a) with respect to 75% of its assets, a portfolio will not purchase 
securities of any issuer if, as a result, more than 5% of the portfolio's 
total assets taken at market value would be invested in the securities of any 
single issuer except that this restriction does not apply to securities 
issued or guaranteed by the U.S. Government or its agencies or 
instrumentalities. This limitation is not applicable to the Global Fixed 
Income, International Fixed Income and Emerging Markets Portfolios. However, 
these portfolios will comply with the diversification requirements imposed by 
Sub-Chapter M of the Internal Revenue Code; 

(b) with respect to 75% of its assets, a Portfolio will not purchase a 
security if, as a result, the portfolio would hold more than 10% of the 
outstanding voting securities of any issuer. This limitation is not 
applicable to the Global Fixed Income, International Fixed Income and 
Emerging Markets Portfolios. However, these portfolios will comply with the 
diversification requirements imposed by Sub-Chapter M of the Internal Revenue 
Code; 

(c) a portfolio will not invest more than 5% of its total assets in the 
securities of issuers (other than securities issued or guaranteed by U.S. or 
foreign governments or political subdivisions thereof) which have (with 
predecessors) a record of less than three years of continuous operation; 

(d) a portfolio will not acquire any securities of companies within one 
industry, if, as a result of such acquisition, more than 25% of the value of 
the portfolio's total assets would be invested in securities of companies 
within such industry; provided, however, that (1) there shall be no 
limitation on the purchase of obligations issued or guaranteed by the U.S. 
Government, its agencies or instrumentalities; (2) the Cash Reserves 
Portfolio may invest without limitation in certificates of deposit or 
bankers' acceptances of domestic banks; (3) utility companies will be divided 
according to their services, for example, gas, gas transmission, electric and 
telephone will each be considered a separate industry; (4) financial service 
companies will be classified according to the end users of their services, 
for example, automobile finance, bank finance and diversified finance will 
each be considered a separate industry; (5) asset-backed securities will be 
classified according to the underlying assets securing such securities, and 
(6) the Mortgage-Backed Securities Portfolio will concentrate in 
mortgage-backed securities.

(e) a portfolio will not make loans except (i) by purchasing debt securities 
in accordance with its investment objectives and policies, or entering into 
Repurchase Agreements, (ii) by lending its portfolio securities and (iii) by 
lending portfolio assets to other portfolios of the Fund, so long as such 
loans are not inconsistent with the Investment Company Act of 1940, as 
amended or the Rules and Regulations, or interpretations or orders of the 
Securities and Exchange Commission thereunder; 


(f) a portfolio will not borrow money, except (i) as a temporary measure for 
extraordinary or emergency purposes or (ii) in connection with reverse 
repurchase agreements provided that (i) and (ii) in combination do not exceed 
33 1/3% of the portfolio's total assets (including the amount borrowed) less 
liabilities (exclusive of borrowings); 


(g) Each portfolio may pledge, mortgage or hypothecate assets in an amount up 
to 50% of its total assets, provided that each portfolio may also segregate 
assets without limit in order to comply with the requirements of Section 
18(f) of the Investment Company Act of 1940, as amended, and applicable 
interpretations thereof published from time to time by the Securities and 
Exchange Commission and its staff. 


(h) a portfolio will not invest its assets in securities of any investment 
company, except by purchase in the open market involving only customary 
brokers' commissions or in connection with mergers, acquisitions of assets or 
consolidations and except as may otherwise be permitted by the Investment 
Company Act of 1940, as amended. 


Limitations (a), (b), (d), (e) and (f), and certain other limitations 
described in the Statement of Additional Information are fundamental and may 
be changed only with the approval of the holders of a majority of the shares 
of each portfolio. The other investment limitations described here and in the 
Statement of Additional Information are not fundamental policies meaning that 
the Board of Trustees may change them without shareholder approval. If a 
percentage limitation on investment or utilization of assets as set forth 
above is adhered to at the time an investment is made, a later change in 
percentage resulting from changes in the value or total cost of the 
portfolio's assets will not be considered a violation of the restriction, and 
the sale of securities will not be required.

Equity Portfolio 

Objective:               To achieve above-average total return over a market
                         cycle of three to five years, consistent with
                         reasonable risk, by investing primarily in
                         dividend-paying common stocks of companies which are
                         deemed by the Adviser to demonstrate long-term earnings
                         growth that is greater than the economy in general and
                         greater than the expected rate of inflation.

Approach:                The Adviser evaluates both short-term and long-term
                         economic trends and their impact on corporate profits
                         and the relative value offered by different sectors and
                         securities within the equity markets. Individual
                         securities are selected based on fundamental business
                         and financial factors (such as earnings growth,
                         financial position, price volatility, and dividend
                         payment records) and the measurement of those factors
                         relative to the current market price of the security.

International Equity Portfolio

Objective:               To achieve above-average total return over a market
                         cycle of three to five years, consistent with
                         reasonable risk, by investing in common stocks of
                         companies based outside of the United States.

Approach:                The Adviser evaluates both short-term and long-term
                         international economic trends and the relative
                         attractiveness of non-U.S. equity markets and
                         individual securities.

Policies:                Generally at least 65% invested in Foreign Equities of
                         issuers in at least 3 countries other than the U.S.
                         Derivatives may be used to pursue portfolio strategy

Mid Cap Growth Portfolio 

Objective:               To achieve long-term capital growth by investing
                         primarily in common stocks of smaller and medium size
                         companies which are deemed by the Adviser to offer
                         long-term growth potential. Due to its emphasis on
                         long-term capital growth, dividend income will be lower
                         than for the Equity and Value Portfolios.

Approach:                The Adviser uses a four-part process combining
                         quantitative, fundamental, and valuation analysis with
                         a strict sales discipline. Stocks that pass an initial
                         screen based on estimate revisions undergo detailed
                         fundamental research. Valuation analysis is used to
                         eliminate the most overvalued securities. Holdings are
                         sold when their estimate-revision scores fall to
                         unacceptable levels, when fundamental research uncovers
                         unfavorable trends, or when their valuations exceed the
                         level that the Adviser believes is reasonable given
                         their growth prospects.

Policies:                Generally at least 65% invested in Equity Securities of
                         mid-cap companies offering long-term growth potential
                         Up to 5% invested in Foreign Equities (excluding ADRs)
                         Derivatives may be used to pursue portfolio strategy

Capitalization Range:    Generally $300 million to $3 billion

                         reasonable risk, by investing in common stocks with

                         represented in the S&P MidCap 400 Index which are
                         deemed by the Adviser to be relatively undervalued
                         based on certain proprietary measures of value. The
                         Portfolio will typically exhibit a lower price/earnings
                         value ratio than the S&P MidCap 400 Index.

Approach:                The Adviser selects common stocks which are deemed to
                         be undervalued at the time of purchase, based on
                         proprietary measures of value. The Portfolio will be
                         structured taking into account the economic sector
                         weights of the S&P MidCap 400 Index, with sector
                         weights normally being within 5% of the sector weights
                         of the Index.

Policies:                Generally at least 65% invested in Equity Securities of
                         mid-cap companies deemed to be undervalued
                         Up to 5% invested in Foreign Equities (excluding ADRs)

Small Cap Value Portfolio (not currently being offered to new investors) 

Objective:               To achieve above-average total return over a market
                         cycle of three to five years, consistent with
                         reasonable risk, by investing in common stocks with

                         are deemed by the Adviser to be relatively undervalued
                         based on certain proprietary measures of value. The
                         Portfolio will typically exhibit lower price/earnings
                         and price/book value ratios than the Russell 2000.
                         Dividend income will typically be lower than for the
                         Equity and Value Portfolios.

Approach:                The Adviser selects common stocks which are deemed to
                         be undervalued at the time of purchase, based on

Value Portfolio 

Objective:               To achieve above-average total return over a market
                         cycle of three to five years, consistent with
                         reasonable risk, by investing in common stocks with
                         equity capitalizations usually greater than $300
                         million which are deemed by the Adviser to be
                         relatively undervalued, based on various measures such
                         as price/earnings ratios and price/book ratios. While
                         capital return will be emphasized somewhat more than
                         income return, the Portfolio's total return will
                         consist of both capital and income returns. It is
                         expected that income return will be higher than that of
                         the Equity Portfolio because stocks which are deemed to
                         be undervalued in the marketplace have, under most
                         market conditions, provided higher dividend income
                         returns than stocks which are deemed to have long-term
                         earnings growth potential which normally sell at higher
                         price/earnings ratios.

Approach:                The Adviser selects common stocks which are deemed to
                         be undervalued relative to the stock market in general
                         as measured by the Standard & Poor's 500 Index, based
                         on the value measures such as price/earnings ratios and
                         price/book ratios, as well as fundamental research.

Policies:                Generally at least 65% invested in Equity Securities
                         deemed to be undervalued 
                         Up to 5% invested in Foreign Equities (excluding ADRs)

Cash Reserves Portfolio 

Objective:               To realize maximum current income, consistent with the
                         preservation of capital and liquidity, by investing in
                         money market instruments and other short-term
                         securities having expected maturities of thirteen
                         months or less. The Portfolio's average weighted
                         maturity will not exceed 90 days. The securities in
                         which the Portfolio will invest may not yield as high a
                         level of current income as securities of lower quality
                         or longer maturities which generally have less
                         liquidity, greater market risk and more price
                         fluctuation. The Portfolio is designed to provide
                         maximum principal stability for investors seeking to
                         invest funds for the short term, or, for investors
                         seeking to combine a long-term investment program in
                         other portfolios of the Fund with an investment in
                         money market instruments. The Portfolio seeks to
                         maintain, but there can be no assurance that it will be
                         able to maintain, a constant net asset value of $1.00
                         per share.

Approach:                The Adviser selects a diversified portfolio of money
                         market securities of government and corporate issuers,
                         any of which may be variable or floating rate, and
                         which have remaining maturities of thirteen months or
                         less from the date of purchase. For the purpose of
                         determining remaining maturity on Floaters, demand
                         features and interest reset dates will be taken into
                         consideration.

Policies:                The Portfolio seeks to maintain, but there can be no
                         assurance that it will be able to maintain, a constant
                         net asset value of $1.00 per share.

                         cycle of three to five years, consistent with
                         reasonable risk, by investing in high yielding
                         corporate fixed-income securities (including bonds

                         techniques and analyses of economic and industry trends
                         to determine portfolio structure. Individual securities
                         are selected, and monitored, by fixed- income portfolio
                         managers who specialize in corporate bonds and use
                         in-depth financial analysis to uncover opportunities in
                         undervalued issues.

International Fixed Income Portfolio - (a non-diversified portfolio) 

Objective:               To achieve above-average total return over a market
                         cycle of three to five years, consistent with
                         reasonable risk, by investing primarily in high-grade
                         fixed-income securities of foreign issuers.

Approach:                The Adviser manages the duration, country, and currency
                         exposure of the portfolio by combining fundamental
                         research on relative values with analyses of economic,
                         interest-rate, and exchange-rate trends. MAS will
                         invest in mortgage and corporate bonds when it believes
                         they offer the most value, although most foreign
                         currency denominated investments are in government and
                         supranational securities.

Policies:                Generally at least 80% invested in Fixed-Income
                         Securities of issuers in at least 3 countries other
                         than the U.S. Derivatives may be used to represent
                         country investments, and otherwise pursue portfolio

Limited Duration Portfolio 

Objective:               To achieve above-average total return over a market
                         cycle of three to five years, consistent with
                         reasonable risk, by investing in a diversified
                         portfolio of U.S. Government securities,
                         investment-grade corporate bonds and other fixed-income
                         securities. The portfolio will maintain an average
                         duration of between one and three years. Duration is a
                         measure of the life of the portfolio's debt securities
                         on a present-value basis and is indicative of a
                         security's price volatility relative to interest rate
                         changes.

Approach:                The Adviser manages the duration of the overall
                         portfolio as a more effective way to control interest-
                         rate risk than limiting the maturity of individual
                         securities within the portfolio. In this way investors
                         can benefit from opportunities across the entire yield
                         curve as well as in various market sectors, and at the
                         same time limit the volatility of investment returns.
                         MAS establishes the duration target through the use of
                         its top-down view of the economy and analysis of the
                         current level of interest rates and the shape of the
                         yield curve. MAS then strives to purchase the most
                         attractively priced portfolio that meets our duration
                         and investment objectives. When purchasing securities
                         other than U.S. Governments, MAS evaluates credit,
                         liquidity, and option risk. When MAS believes the
                         portfolio is compensated for these risks, it includes
                         agency, mortgage, and corporate securities which meet
                         the Portfolio's quality specifications.

Policies:                Generally at least 65% invested in Fixed-Income

Mortgage-Backed Securities Portfolio 

Objective:               To achieve above-average total return over a market
                         cycle of three to five years, consistent with
                         reasonable risk, by investing primarily (at least 65%
                         of its assets under normal circumstances) in
                         mortgage-backed securities. In addition, the portfolio
                         may also invest in U.S. government securities and in
                         short-term fixed-income securities such as certificates
                         of deposit, treasury bills, and commercial paper. The
                         portfolio's average weighted maturity will ordinarily
                         be greater than seven years.

Approach:                The Adviser sets three portfolio targets: (1)
                         interest-rate sensitivity; (2) yield-curve sensitivity;
                         and (3) prepayment sensitivity. The Adviser increases
                         the sensitivity of the portfolio to changes in interest
                         rates when bonds offer greater value on the basis of
                         inflation-adjusted interest rates. Similarly, the
                         Adviser increases yield-curve sensitivity when
                         long-maturity interest rates offer exceptional value
                         relative to short-maturity interest rates. Finally, the
                         Adviser increases prepayment exposure when mortgage
                         yields, adjusted for probable prepayments, indicate
                         unusual value in mortgage-backed securities.

Policies:                Generally at least 65% invested in Mortgage Securities
                         Derivatives may be used to pursue portfolio strategy

Objective:               To realize above-average total return over a market
                         cycle of three to five years, consistent with the
                         conservation of capital and the realization of current
                         income which is exempt from federal income tax, by
                         investing in a diversified portfolio of fixed income
                         securities.

Approach:                The Adviser varies portfolio structure--the average
                         duration and maturity and the amount of the portfolio
                         invested in various types of bonds--according to its

                         bonds. The portfolio will invest in taxable bonds only

Special Purpose Fixed Income Portfolio 

Objective:               To achieve above-average total return over a market
                         cycle of three to five years, consistent with
                         reasonable risk, by investing in a diversified
                         portfolio of U.S. Government securities, corporate
                         bonds (including bonds rated below investment grade,
                         commonly referred to as junk bonds), foreign fixed-
                         income securities and mortgage-backed securities and
                         other fixed-income securities. The portfolio is
                         structured to complement an investment in one or more
                         of the Fund's equity portfolios for investors seeking a
                         balanced investment.

Approach:                The Adviser actively manages the maturity and duration
                         structure of the portfolio in anticipation of long-term
                         trends in interest rates and inflation. Investments are
                         diversified among a wide variety of Fixed-Income
                         Securities in all market sectors. Both
                         duration/maturity strategy and sector allocation are
                         determined based on the presumption that investors are
                         combining an investment in the portfolio with an equity
                         investment.

Policies:                Generally at least 65% invested in Fixed-Income
                         Securities May invest greater than 50% in Mortgage

Balanced Portfolio 

Objective:               To achieve above average total return over a market
                         cycle of three to five years, consistent with
                         reasonable risk, by investing in a diversified
                         portfolio of common stocks and fixed-income securities.
                         When the Adviser judges the relative outlook for the
                         equity and fixed- income markets to be neutral the
                         portfolio will be invested 60% in common stocks and 40%
                         in fixed-income securities. The asset mix may be
                         changed, however, with common stocks ordinarily
                         representing between 45% and 75% of the total
                         investment. The average weighted maturity of the
                         fixed-income portion of the portfolio will ordinarily
                         be greater than five years.

Approach:                The Adviser determines investment strategies for the
                         equity and fixed-income portions of the portfolio
                         separately and then determine the mix of those
                         strategies expected to maximize the return available
                         from both the stock and bond markets. Strategic
                         judgments on the equity/fixed-income asset mix are
                         based on valuation disciplines and tools for analysis
                         developed by the Adviser over its twenty-five year
                         history of managing balanced accounts.

Policies:                Generally 45% to 75% invested in Equity Securities
                         Up to 25% invested in Foreign Bonds and/or Foreign
                         Equities (excluding ADRs) 
                         Up to 10% invested in Brady Bonds
                         At least 25% invested in senior Fixed-Income Securities

           CHARACTERISTICS AND RISKS OF STRATEGIES AND INVESTMENTS 

STRATEGIES 

   Asset Allocation Management: The Adviser's approach to asset allocation 
management is to determine investment strategies for each asset class in a 
portfolio separately, and then determine the mix of those strategies expected 
to maximize the return available from each market. Strategic judgments on the 
mix among asset classes are based on valuation disciplines and tools for 
analysis which have been developed over the Adviser's twenty-five year 
history of managing balanced accounts. 

   Tactical asset-allocation shifts are based on comparisons of prospective 
risks, returns, and the likely risk-reducing benefits derived from combining 
different asset classes into a single portfolio. Experienced teams of equity, 
fixed- income, and international investment professionals manage the 
investments in each asset class. 

   Core Equity Investing: The Adviser's "core" or primary equity strategy 
emphasizes common stocks of large companies, with targeted investments in 
small company stocks that promise special growth opportunities. Depending on 
MAS's outlook for the economy and different market sectors, the mix between 
value stocks and growth stocks will change. 

   Emerging Markets Investing: The Adviser's approach to emerging markets 
investing is based on the Adviser's evaluation of both short-term and 
long-term international economic trends and the relative attractiveness of 
emerging markets and individual emerging market securities. 

   As used in this Prospectus, emerging markets describes any country which 
is generally considered to be an emerging or developing country by the 
international financial community such as the International Bank for 
Reconstruction and Development (more commonly known as the World Bank) and 
the International Finance Corporation. There are currently over 130 countries 
which are generally considered to be emerging or developing countries by the 
international financial community, approximately 40 of which currently have 
stock markets. Emerging markets can include every nation in the world except 
the United States, Canada, Japan, Australia, New Zealand and most nations 
located in Western Europe. 

   Currently, investing in many emerging markets is either not feasible or 
very costly, or may involve unacceptable political risks. Other special risks 
include the possible increased likelihood of expropriation or the return to 
power of a communist regime which would institute policies to expropriate, 
nationalize or otherwise confiscate investments. A portfolio will focus its 
investments on those emerging market countries in which the Adviser believes 
the potential for market appreciation outweighs these risks and the cost of 
investment. Investing in emerging markets also involves an extra degree of 
custodial and/or market risk, especially where the securities purchased are 
not traded on an official exchange or where ownership records regarding the 
securities are maintained by an unregulated entity (or even the issuer 
itself). 

   Fixed Income Management and Asset Allocation: Within the Balanced, 
Multi-Asset-Class and Special Purpose Fixed Income Portfolios, the Adviser 
selects fixed-income securities not only on the basis of judgments regarding 
Maturity and Duration Management and Value Investing, but also on the basis 
of the value offered by various segments of the fixed-income securities 
market relative to Cash Equivalents and Equity Securities. In this context, 
the Adviser may find that certain segments of the fixed-income securities 
market offer more or less attractive relative value when compared to Equity 
Securities than when compared to other Fixed-Income Securities. 

   For example, in a given interest rate environment, equity securities may 
be judged to be fairly valued when compared to intermediate duration 
fixed-income securities, but overvalued compared to long duration 
fixed-income securities. Consequently, while a portfolio investing only in 
fixed-income securities may not emphasize long duration assets to the same 
extent, the fixed-income portion of a balanced investment may invest a 
percentage of its assets in long duration bonds on the basis of their 
valuation relative to equity securities.

   Foreign Fixed Income Investing: The Adviser invests in Foreign Bonds and 
other Fixed-Income Securities denominated in foreign currencies, where, in 
the opinion of the Adviser, the combination of current yield and currency 
value offer attractive expected returns. When the total return opportunities 
in a foreign bond market appear attractive in local currency terms, but where 
in the Adviser's judgment unacceptable currency risk exists, currency Futures 
& Options, Forwards and Swaps may be used to hedge the currency risk. 

   Foreign Investing: Investors should recognize that investing in Foreign 
Bonds and Foreign Equities involves certain special considerations which are 
not typically associated with investing in domestic securities. 

   As non-U.S. companies are not generally subject to uniform accounting, 
auditing and financial reporting standards and practices comparable to those 
applicable to U.S. companies, there may be less publicly available 
information about certain foreign securities than about U.S. securities. 
Foreign Bonds and Foreign Equities may be less liquid and more volatile than 
securities of comparable U.S. companies. There is generally less government 
supervision and regulation of stock exchanges, brokers and listed companies 
than in the U.S. With respect to certain foreign countries, there is the 
possibility of expropriation or confiscatory taxation, political or social 
instability, or diplomatic developments which could affect U.S. investments 
in those countries. Additionally, there may be difficulty in obtaining and 
enforcing judgments against foreign issuers. 

   Since Foreign Bonds and Foreign Equities may be denominated in foreign 
currencies, and since a portfolio may temporarily hold uninvested reserves in 
bank deposits of foreign currencies prior to reinvestment or conversion to 
U.S. dollars, a portfolio may be affected favorably or unfavorably by changes 
in currency rates and in exchange control regulations, and may incur costs in 
connection with conversions between various currencies. 

   Although a portfolio will endeavor to achieve the most favorable execution 
costs in its portfolio transactions in foreign securities, fixed commissions 
on many foreign stock exchanges are generally higher than negotiated 
commissions on U.S. exchanges. In addition, it is expected that the expenses 
for custodial arrangements of a portfolio's foreign securities will be 
greater than the expenses for the custodial arrangements for handling U.S. 
securities of equal value. Certain foreign governments levy withholding taxes 
against dividend and interest income. Although in some countries a portion of 
these taxes is recoverable, the non-recovered portion of foreign withholding 
taxes will reduce the income a portfolio receives from the companies 
comprising the portfolio's investments. 

   Growth Stock Investing: Seeks to invest in Common Stocks generally 
characterized by higher growth rates, betas, and price/earnings ratios, and 
lower yields than the stock market in general as measured by the S&P 500 
Index. 

   High Yield Investing: Involves investing in high yield securities based on 
the Adviser's analysis of economic and industry trends and individual 
security characteristics. The Adviser conducts credit analysis for each 
security considered for investment to evaluate its attractiveness relative to 
its risk. A high level of diversification is also maintained to limit credit 
exposure to individual issuers. 

   To the extent a portfolio invests in high yield securities it will be 
exposed to a substantial degree of credit risk. Lower-rated bonds are 
considered speculative by traditional investment standards. High yield 
securities may be issued as a consequence of corporate restructuring or 
similar events. Also, high yield securities are often issued by smaller, less 
credit worthy companies, or by highly leveraged (indebted) firms, which are 
generally less able than more established or less leveraged firms to make 
scheduled payments of interest and principal. The risks posed by securities 
issued under such circumstances are substantial. 

   The market for high yield securities is still relatively new. Because of 
this, a long-term track record for bond default rates does not exist. In 
addition, the secondary market for high yield securities is generally less 
liquid than that for investment grade corporate securities. In periods of 
reduced market liquidity, high yield bond prices may become more volatile, 
and both the high yield market and a portfolio may experience sudden and 
substantial price declines. This lower liquidity might have an effect on a 
portfolio's ability to value or dispose of such securities. Also, there 

- -------------------------------------------------------------------------------

<PAGE>

may be significant disparities in the prices quoted for high yield securities 
by various dealers. Under such conditions, a portfolio may find it difficult 
to value its securities accurately. A portfolio may also be forced to sell 
securities at a significant loss in order to meet shareholder redemptions. 
These factors add to the risks associated with investing in high yield 
securities. 

   High yield bonds may also present risks based on payment expectations. For 
example, high yield bonds may contain redemption or call provisions. If an 
issuer exercises these provisions in a declining interest rate market, a 
portfolio would have to replace the security with a lower yielding security, 
resulting in a decreased return for investors. Conversely, a high yield 
bond's value will decrease in a rising interest rate market. 

   Certain types of high yield bonds are non-income paying securities. For 
example, zero coupon bonds pay interest only at maturity and payment-in-kind 
bonds pay interest in the form of additional securities. Payment in the form 
of additional securities, or interest income recognized through discount 
accretion, will, however, be treated as ordinary income which will be 
distributed to shareholders even though the portfolio does not receive 
periodic cash flow from these investments. 

   The table below provides a summary of ratings assigned to all U.S. and 
foreign debt holdings of those portfolios with more than 5% invested in High 
Yield securities (not including money market instruments). These figures are 
dollar-weighted averages of month-end portfolio holdings and do not 
necessarily indicate a portfolio's current or future debt holdings. 
Portfolios whose debt holdings total less than 100% also invest in Equity 
Securities.

<PAGE>

International Equity Investing: The Adviser's approach to international 
equity investing is based on its evaluation of both short-term and long-term 
international economic trends and the relative attractiveness of non-U.S. 
equity markets and individual securities. 

MAS considers fundamental investment characteristics, the principles of 
valuation and diversification, and a relatively long-term investment time 
horizon. Since liquidity will also be a consideration, emphasis will likely 
be influenced by the relative market capitalizations of different non-U.S. 
stock markets and individual securities. Portfolios seek to diversify 
investments broadly among both developed and newly industrializing foreign 
countries. Where appropriate, a portfolio may also invest in regulated 
Investment Companies or Investment Funds which invest in such countries to 
the extent allowed by applicable law. 

Maturity and Duration Management: One of two primary components of the 
Adviser's fixed-income investment strategy is maturity and duration 
management. The maturity and duration structure of a portfolio investing in 
Fixed-Income Securities is actively managed in anticipation of cyclical 
interest rate changes. Adjustments are not made in an effort to capture 
short-term, day-to-day movements in the market, but instead are implemented 
in anticipation of longer term shifts in the levels of interest rates. 
Adjustments made to shorten portfolio maturity and duration are made to limit 
capital losses during periods when interest rates are expected to rise. 
Conversely, adjustments made to lengthen maturity are intended to produce 
capital appreciation in periods when interest rates are expected to fall. The 
foundation for maturity and duration strategy lies in analysis of the U.S. 
and global economies, focusing on levels of real interest rates, monetary and 
fiscal policy actions, and cyclical indicators. See Value Investing for a 
description of the second primary component of the Adviser's fixed-income 
strategy. 

About Maturity and Duration: Most debt obligations provide interest (coupon) 
payments in addition to a final (par) payment at maturity. Some obligations 
also have call provisions. Depending on the relative magnitude of these 
payments and the nature of the call provisions, the market values of debt 
obligations may respond differently to changes in the level and structure of 
interest rates. Traditionally, a debt security's term-to-maturity has been 
used as a proxy for the sensitivity of the security's price to changes in 
interest rates (which is the interest rate risk or volatility of the 
security). However, term-to-maturity measures only the time until a debt 
security provides its final payment, taking no account of the pattern of the 
security's payments prior to maturity. 

Duration is a measure of the expected life of a fixed-income security that 
was developed as a more precise alternative to the concept of 
term-to-maturity. Duration incorporates a bond's yield, coupon interest 
payments, final maturity and call features into one measure. Duration is one 
of the fundamental tools used by the Adviser in the selection of fixed-income 
securities. Duration is a measure of the expected life of a fixed-income 
security on a present value basis. Duration takes the length of the time 
intervals between the present time and the time that the interest and 
principal payments are scheduled or, in the case of a callable bond, expected 
to be received, and weights them by the present values of the cash to be 
received at each future point in time. For any fixed-income security with 
interest payments occurring prior to the payment of principal, duration is 
always less than maturity. In general, all other factors being the same, the 
lower the stated or coupon rate of interest of a fixed-income security, the 
longer the duration of the security; conversely, the higher the stated or 
coupon rate of interest of a fixed- income security, the shorter the duration 
of the security. 

There are some situations where even the standard duration calculation does 
not properly reflect the interest rate exposure of a security. For example, 
floating and variable rate securities often have final maturities of ten or 
more years; however, their interest rate exposure corresponds to the 
frequency of the coupon reset. Another example where the interest rate 
exposure is not properly captured by duration is the case of mortgage 
pass-through securities. The stated final maturity of such securities is 
generally 30 years, but current prepayment rates are more critical in 
determining the securities' interest rate exposure. In these and other 
similar situations, the Adviser will use sophisticated analytical techniques 
that incorporate the economic life of a security into the determination of 
its interest rate exposure. 

Money Market Investing: A money market fund like the Cash Reserves Portfolio 
invests in securities which present minimal credit risk and may not yield as 
high a level of current income as securities of lower quality or longer 
maturities which generally have less liquidity, greater market risk and more 
price fluctuation. A money market portfolio is designed to provide maximum 
principal stability for investors seeking to invest funds for the short- 

- -------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 41
<PAGE>

term, or, for investors seeking to combine a long-term investment program in 
other portfolios of the Fund with an investment in money market instruments. 
However, because the Cash Reserves Portfolio invests in the money market 
obligations of private financial and non-financial corporations in addition 
to those of the U.S. Government or its agencies and instrumentalities, it 
offers higher credit risk and yield potential relative to money market funds 
which invest exclusively in U.S. Government securities. The Cash Reserves 
Portfolio seeks to maintain, but does not guarantee, a constant net asset 
value of $1.00 per share. 

Mortgage Investing: At times it is anticipated that greater than 50% of a 
fixed-income portfolio's assets may be invested in mortgage-related 
securities. These include mortgage-backed securities, which represent 
interests in pools of mortgage loans made by lenders such as commercial 
banks, savings and loan associations, mortgage bankers and others. The pools 
are assembled by various organizations, including the Government National 
Mortgage Association (GNMA), Federal Home Loan Mortgage Corporation (FHLMC), 
Federal National Mortgage Association (FNMA), other government agencies, and 
private issuers. It is expected that a portfolio's primary emphasis will be 
on mortgage-backed securities issued by the various Government-related 
organizations. However, a portfolio may invest, without limit, in 
mortgage-backed securities issued by private issuers when the Adviser deems 
that the quality of the investment, the quality of the issuer, and market 
conditions warrant such investments. Securities issued by private issuers 
will be rated investment grade by Moody's or Standard & Poor's or be deemed 
by the Adviser to be of comparable investment quality. 

Municipals Management: MAS manages municipal portfolios in a total return 
context. This means that taxable investments will regularly be included in a 
portfolio when they have an attractive prospective after-tax total return, 
regardless of the taxable nature of income on the security. 

MAS Municipals Management emphasizes a diversified portfolio of high grade 
municipal debt securities. Under normal circumstances, a portfolio will 
invest at least 80% of net assets in municipal securities including AMT Bonds 
and at least 80% will be Investment Grade Securities. 

Under normal conditions, a portfolio may hold up to 20% of net assets in U.S. 
Governments, Agencies, Corporates, Cash Equivalents, Preferred Stocks, 
Mortgage Securities, Asset-Backeds, Floaters, and Inverse Floaters and other 
Fixed Income Securities (collectively "Taxable Investments"). 

Non-Diversified Status: A portfolio may be classified as a non-diversified 
investment company under the Investment Company Act of 1940, as amended. 
Non-diversified portfolios may invest more than 25% of assets in securities 
of individual issuers representing greater than 5% each of a portfolio's 
total assets, whereas diversified investment companies may only invest up to 
25% of assets in positions of greater than 5%. Both diversified and non- 
diversified portfolios are subject to diversification specifications under 
the Internal Revenue Code of 1986, as amended, which require that, as of the 
close of each fiscal quarter, (i) no more than 25% of a portfolio's total 
assets may be invested in the securities of a single issuer (except for U.S. 
Government securities) and (ii) with respect to 50% of its total assets, no 
more than 5% of such assets may be invested in the securities of a single 
issuer (except for U.S. Government securities) or invested in more than 10% 
of the outstanding voting securities of a single issuer. Because of its 
non-diversified status, a portfolio may be subject to greater credit and 
other risks than a diversified investment company. 

Value Investing: One of two primary components of the Adviser's fixed-income 
strategy is value investing, whereby MAS seeks to identify undervalued 
sectors and securities through analysis of credit quality, option 
characteristics and liquidity. Quantitative models are used in conjunction 
with judgment and experience to evaluate and select securities with embedded 
put or call options which are attractive on a risk- and option-adjusted 
basis. Successful value investing will permit a portfolio to benefit from the 
price appreciation of individual securities during periods when interest 
rates are unchanged. See Maturity and Duration Management for a description 
of the other key component of MAS's fixed-income investment strategy.

<PAGE>

Value Stock Investing: Emphasizes Common Stocks which are deemed by the 
Adviser to be undervalued relative to the stock market in general as measured 
by the appropriate market index, based on value measures such as 
price/earnings ratios and price/book ratios. Value stocks are generally 
dividend paying common stocks. However, non-dividend paying stocks may also 
be selected for their value characteristics. 

INVESTMENTS 

Each Portfolio may invest in the securities defined below in accordance with 
their listing of Allowable Investments and any quality or policy constraints. 

ADRs--American Depository Receipts: are dollar-denominated securities which 
are listed and traded in the United States, but which represent claims to 
shares of foreign stocks. ADRs may be either sponsored or unsponsored. 
Unsponsored ADR facilities typically provide less information to ADR holders. 

Agencies: are securities which are not guaranteed by the U.S. Government, but 
which are issued, sponsored or guaranteed by a federal agency or federally 
sponsored agency such as the Student Loan Marketing Association, Resolution 
Funding Corporation, or any of several other agencies. 

Asset-Backeds: are securities collateralized by shorter term loans such as 
automobile loans, home equity loans, computer leases, or credit card 
receivables. The payments from the collateral are passed through to the 
security holder. The collateral behind asset-backed securities tends to have 
prepayment rates that do not vary with interest rates. In addition the 
short-term nature of the loans reduces the impact of any change in prepayment 
level. Due to amortization, the average life for these securities is also the 
conventional proxy for maturity. 

Possible Risks: Due to the possibility that prepayments (on automobile loans 
and other collateral) will alter the cash flow on asset-backed securities, it 
is not possible to determine in advance the actual final maturity date or 
average life. Faster prepayment will shorten the average life and slower 
prepayments will lengthen it. However, it is possible to determine what the 
range of that movement could be and to calculate the effect that it will have 
on the price of the security. In selecting these securities, the Adviser will 
look for those securities that offer a higher yield to compensate for any 
variation in average maturity. 

Brady Bonds: are debt obligations which are created through the exchange of 
existing commercial bank loans to foreign entities for new obligations in 
connection with debt restructuring under a plan introduced by former U.S. 
Secretary of the Treasury, Nicholas F. Brady (the Brady Plan). Brady Bonds 
have been issued only recently, and, accordingly, do not have a long payment 
history. They may be collateralized or uncollateralized and issued in various 
currencies (although most are dollar-denominated) and they are actively 
traded in the over-the-counter secondary market. For further information on 
these securities, see the Statement of Additional Information. Portfolios 
will only invest in Brady Bonds consistent with quality specifications. 

Cash Equivalents: are short-term fixed-income instruments comprising: 

(1) Time deposits, certificates of deposit (including marketable variable 
rate certificates of deposit) and bankers' acceptances issued by a commercial 
bank or savings and loan association. Time deposits are non-negotiable 
deposits maintained in a banking institution for a specified period of time 
at a stated interest rate. Certificates of deposit are negotiable short-term 
obligations issued by commercial banks or savings and loan associations 
against funds deposited in the issuing institution. Variable rate 
certificates of deposit are certificates of deposit on which the interest 
rate is periodically adjusted prior to their stated maturity based upon a 
specified market rate. A bankers' acceptance is a time draft drawn on a 
commercial bank by a borrower usually in connection with an international 
commercial transaction (to finance the import, export, transfer or storage of 
goods). 

A portfolio may invest in obligations of U.S. banks, foreign branches of U.S. 
banks (Eurodollars), and U.S. branches of foreign banks (Yankee dollars). 
Euro and Yankee dollar investments will involve some of the same risks of 
investing in international securities that are discussed in the Foreign 
Investing section of this Prospectus. 

- -------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 43
<PAGE>

Portfolios will not invest in any security issued by a commercial bank unless 
(i) the bank has total assets of at least $1 billion, or the equivalent in 
other currencies, or, in the case of domestic banks which do not have total 
assets of at least $1 billion, the aggregate investment made in any one such 
bank is limited to $100,000 and the principal amount of such investment is 
insured in full by the Federal Deposit Insurance Corporation, (ii) in the 
case of U.S. banks, it is a member of the Federal Deposit Insurance 
Corporation, and (iii) in the case of foreign branches of U.S. banks, the 
security is deemed by the Adviser to be of an investment quality comparable 
with other debt securities which may be purchased by the portfolio. 

(2) Each portfolio (except Cash Reserves) may invest in commercial paper 
rated at time of purchase by one or more NRSRO in one of their two highest 
categories, (e.g., A-l or A-2 by Standard & Poor's or Prime 1 or Prime 2 by 
Moody's), or, if not rated, issued by a corporation having an outstanding 
unsecured debt issue rated high-grade by a NRSRO (e.g. A or better by 
Moody's, Standard & Poor's or Fitch). The Cash Reserves Portfolio invests 
only in commercial paper rated in the highest category; 

(3) Short-term corporate obligations rated high-grade at the time of purchase 
by a NRSRO (e.g. A or better by Moody's, Standard & Poor's or Fitch); 

(4) U.S. Government obligations including bills, notes, bonds and other debt 
securities issued by the U.S. Treasury. These are direct obligations of the 
U.S. Government and differ mainly in interest rates, maturities and dates of 
issue; 

(5) Securities issued or guaranteed by U.S. Government sponsored 
instrumentalities and Federal agencies. These include securities issued by 
the Federal Home Loan Banks, Federal Land Bank, Farmers Home Administration, 
Farm Credit Banks, Federal Intermediate Credit Bank, Federal National 
Mortgage Association, Federal Financing Bank, the Tennessee Valley Authority, 
and others; 

(6) Repurchase agreements collateralized by securities listed above; and 

(7) Investments by the Cash Reserve Portfolio in Cash Equivalents are limited 
by the quality, maturity and diversification requirements adopted under Rule 
2a-7 of the 1940 Act. 

CMOs--Collateralized Mortgage Obligations: are Derivatives which are 
collateralized by mortgage pass-through securities. Cash flows from the 
mortgage pass-through securities are allocated to various tranches (a 
"tranche" is essentially a separate security) in a predetermined, specified 
order. Each tranche has a stated maturity -- the latest date by which the 
tranche can be completely repaid, assuming no prepayments -- and has an 
average life -- the average of the time to receipt of a principal payment 
weighted by the size of the principal payment. The average life is typically 
used as a proxy for maturity because the debt is amortized (repaid a portion 
at a time), rather than being paid off entirely at maturity, as would be the 
case in a straight debt instrument. 

Possible Risks: Due to the possibility that prepayments (on home mortgages 
and other collateral) will alter the cash flow on CMOs, it is not possible to 
determine in advance the actual final maturity date or average life. Faster 
prepayment will shorten the average life and slower prepayments will lengthen 
it. However, it is possible to determine what the range of that movement 
could be and to calculate the effect that it will have on the price of the 
security. In selecting these securities, the Adviser will look for those 
securities that offer a higher yield to compensate for any variation in 
average maturity. 


Like bonds in general, mortgage-backed securities will generally decline in 
price when interest rates rise. Due to prepayment risk, rising interest rates 
also tend to discourage refinancings of home mortgages with the result that 
the average life of mortgage securities held by a portfolio may be 
lengthened. This extension of average life causes the market price of the 
securities to decrease further than if their average lives were fixed. In 
part to compensate for these risks, mortgages will generally offer higher 
yields than comparable bonds. However, when interest rates fall, mortgages 
may not enjoy as large a gain in market value due to prepayment risk because 
additional mortgage prepayments must be reinvested at lower interest rates.

Common Stocks: are Equity Securities which represent an ownership interest in 
a corporation, entitling the shareholder to voting rights and receipt of 
dividends paid based on proportionate ownership. 

Convertibles: are convertible bonds or shares of convertible Preferred Stock 
which may be exchanged for a fixed number of shares of Common Stock at the 
purchaser's option. 

Corporates--corporate bonds: are debt instruments issued by private 
corporations. Bondholders, as creditors, have a prior legal claim over common 
and preferred stockholders of the corporation as to both income and assets 
for the principal and interest due to the bondholder. A portfolio will buy 
Corporates subject to any quality constraints. If a security held by a 
portfolio is down-graded, the portfolio may retain the security if the 
Adviser deems retention of the security to be in the best interests of the 
portfolio. 

Derivatives: A financial instrument whose value and performance are based on 
the value and performance of another security or financial instrument. The 
Adviser will use derivatives only in circumstances where they offer the most 
economic means of improving the risk/reward profile of the portfolio. The 
Adviser will not use derivatives to increase portfolio risk above the level 
that could be achieved in the portfolio using only traditional investment 
securities. In addition, the Adviser will not use derivatives to acquire 
exposure to changes in the value of assets or indexes of assets that are not 
listed in the applicable Allowable Investments for the portfolio. Any 
applicable limitations are described under each investment definition. All of 
the portfolios of MAS Funds, except the Cash Reserves Portfolio, may enter 
into over-the-counter Derivatives transactions (Swaps, Caps, Floors, Puts, 
etc., but excluding CMOs, Forwards, Futures and Options, and SMBS) with 
counterparties approved by MAS in accordance with guidelines established by 
the Board of Trustees. These guidelines provide for a minimum credit rating 
for each counterparty and various credit enhancement techniques (for example, 
collateralization of amounts due from counterparties) to limit exposure to 
counterparties with ratings below AA. Derivatives include, but are not 
limited to, CMOs, Forwards, Futures and Options, SMBS, Structured 
Investments, Structured Notes and Swaps. See each individual Portfolio's 
listing of Allowable Investments to determine which of these the Portfolio 
may hold. 

Eastern European Issuers: The economies of Eastern European countries are 
currently suffering both from the stagnation resulting from centralized 
economic planning and control and the higher prices and unemployment 
associated with the transition to market economics. Unstable economic and 
political conditions may adversely affect security values. Upon the accession 
to power of Communist regimes approximately 40 years ago, the governments of 
a number of Eastern European countries expropriated a large amount of 
property. The claims of many property owners against those governments were 
never finally settled. In the event of the return to power of the Communist 
Party, there can be no assurance that the portfolio's investments in Eastern 
Europe would not be expropriated, nationalized or otherwise confiscated. 

Emerging Markets Issuers: An emerging market security is one issued by a 
company that has one or more of the following characteristics: (i) its 
principal securities trading market is in an emerging market, (ii) alone or 
on a consolidated basis it derives 50% or more of its annual revenue from 
either goods produced, sales made or services performed in emerging markets, 
or (iii) it is organized under the laws of, and has a principal office in, an 
emerging market country. The Adviser will base determinations as to 
eligibility on publicly available information and inquiries made to the 
companies. Investing in emerging markets may entail purchasing securities 
issued by or on behalf of entities that are insolvent, bankrupt, in default 
or otherwise engaged in an attempt to reorganize or reschedule their 
obligations, and in entities that have little or no proven credit rating or 
credit history. In any such case, the issuer's poor or deteriorating 
financial condition may increase the likelihood that the investing fund will 
experience losses or diminution in available gains due to bankruptcy, 
insolvency or fraud. 

Equity Securities: Commonly include but are not limited to Common Stock, 
Preferred Stock, ADRs, Rights, Warrants, Convertibles, and Foreign Equities. 
See each individual portfolio listing of Allowable Investments to determine 
which of the above the portfolio can hold. Preferred Stock is contained in 
both the definition of Equity Securities and Fixed-Income Securities since it 
exhibits characteristics commonly associated with each type.

Fixed-Income Securities: Commonly include but are not limited to U.S. 
Governments, Zero Coupons, Agencies, Corporates, High Yield, Mortgage 
Securities, SMBS, CMOs, Asset-Backeds, Convertibles, Brady Bonds, Floaters, 
Inverse Floaters, Cash Equivalents, Repurchase Agreements, Preferred Stock, 
and Foreign Bonds. See each individual portfolio listing of Allowable 
Investments to determine which securities a portfolio may hold. Preferred 
Stock is contained in both the definition of Equity Securities and 
Fixed-Income Securities since it exhibits characteristics commonly associated 
with each type of security. 

Floaters--Floating and Variable Rate Obligations: are debt obligations with a 
floating or variable rate of interest, i.e. the rate of interest varies with 
changes in specified market rates or indices, such as the prime rate, or at 
specified intervals. Certain floating or variable rate obligations may carry 
a demand feature that permits the holder to tender them back to the issuer of 
the underlying instrument, or to a third party, at par value prior to 
maturity. When the demand feature of certain floating or variable rate 
obligations represents an obligation of a foreign entity, the demand feature 
will be subject to certain risks discussed under Foreign Investing. 

Foreign Bonds: are Fixed-Income Securities denominated in foreign currency 
and issued and traded primarily outside of the U.S., including: (1) 
obligations issued or guaranteed by foreign national governments, their 
agencies, instrumentalities, or political subdivisions; (2) debt securities 
issued, guaranteed or sponsored by supranational organizations established or 
supported by several national governments, including the World Bank, the 
European Community, the Asian Development Bank and others; (3) non-government 
foreign corporate debt securities; and (4) foreign Mortgage Securities and 
various other mortgage and asset-backed securities. 

Foreign Currency: Portfolios investing in foreign securities will regularly 
transact security purchases and sales in foreign currencies. These portfolios 
may hold foreign currency or purchase or sell currencies on a forward basis 
(see Forwards). 

Foreign Equities: are Common Stock, Preferred Stock, Rights and Warrants of 
foreign issuers denominated in foreign currency and traded primarily in 
non-U.S. markets. Investing in foreign companies involves certain special 
considerations which are not typically associated with investing in U.S. 
companies (see Foreign Investing). 

Forwards--Forward Foreign Currency Exchange Contracts: are Derivatives which 
are used to protect against uncertainty in the level of future foreign 
exchange rates. A forward foreign currency exchange contract is an obligation 
to purchase or sell a specific currency at a future date, which may be any 
fixed number of days from the date of the contract agreed upon by the 
parties, at a price set at the time of the contract. Such contracts do not 
eliminate fluctuations caused by changes in the local currency prices of the 
securities, but rather, they establish an exchange rate at a future date. 
Also, although such contracts can minimize the risk of loss due to a decline 
in the value of the hedged currency, at the same time they limit any 
potential gain that might be realized. 

A portfolio may use currency exchange contracts in the normal course of 
business to lock in an exchange rate in connection with purchases and sales 
of securities denominated in foreign currencies (transaction hedge) or to 
lock in the U.S. dollar value of portfolio positions (position hedge). In 
addition the portfolios may cross-hedge currencies by entering into a 
transaction to purchase or sell one or more currencies that are expected to 
decline in value relative to other currencies to which a portfolio has or 
expects to have portfolio exposure. Portfolios may also engage in proxy 
hedging which is defined as entering into positions in one currency to hedge 
investments denominated in another currency, where the two currencies are 
economically linked. A portfolio's entry into forward contracts, as well as 
any use of cross or proxy hedging techniques will generally require the 
portfolio to hold liquid securities or cash equal to the portfolio's 
obligations in a segregated account throughout the duration of the contract. 

A portfolio may also combine forward contracts with investments in securities 
denominated in other currencies in order to achieve desired credit and 
currency exposures. Such combinations are generally referred to as synthetic 
securities. For example, in lieu of purchasing a foreign bond, a portfolio 
may purchase a U.S. dollar-denominated security and at the same time enter 
into a forward contract to exchange U.S. dollars for the contract's 
underlying 

- -------------------------------------------------------------------------------
MAS Funds - 46        Terms in bold type are defined in the Prospectus Glossary

<PAGE>

currency at a future date. By matching the amount of U.S. dollars to be 
exchanged with the anticipated value of the U.S. dollar-denominated security, 
a portfolio may be able to lock in the foreign currency value of the security 
and adopt a synthetic investment position reflecting the credit quality of 
the U.S. dollar-denominated security. 

There is a risk in adopting a transaction hedge or position hedge to the 
extent that the value of a security denominated in foreign currency is not 
exactly matched with a portfolio's obligation under the forward contract. On 
the date of maturity, a portfolio may be exposed to some risk of loss from 
fluctuations in that currency. Although the Adviser will attempt to hold such 
mismatching to a minimum, there can be no assurance that the Adviser will be 
able to do so. For proxy hedges, cross-hedges or a synthetic position, there 
is an additional risk in that these transactions create residual foreign 
currency exposure. When a portfolio enters into a forward contract for 
purposes of creating a position hedge, transaction hedge, cross hedge or a 
synthetic security, it will generally be required to hold liquid securities 
or cash in a segregated account with a daily value at least equal to its 
obligation under the forward contract. 

Futures & Options--Futures Contracts, Options on Futures Contracts and 
Options: are Derivatives. Futures contracts provide for the sale by one party 
and purchase by another party of a specified amount of a specific security, 
at a specified future time and price. An option is a legal contract that 
gives the holder the right to buy or sell a specified amount of the 
underlying security or futures contract at a fixed or determinable price upon 
the exercise of the option. A call option conveys the right to buy and a put 
option conveys the right to sell a specified quantity of the underlying 
security. 

A portfolio will not enter into futures contracts to the extent that its 
outstanding obligations to purchase securities under these contracts in 
combination with its outstanding obligations with respect to options 
transactions would exceed 50% of its total assets. It will maintain assets 
sufficient to meet its obligations under such contracts in a segregated 
account with the custodian bank or will otherwise comply with the SEC's 
position on asset coverage. 

Possible Risks: The primary risks associated with the use of futures and 
options are (i) imperfect correlation between the change in market value of 
the securities held by a portfolio and the prices of futures and options 
relating to the stocks, bonds or futures contracts purchased or sold by a 
portfolio; and (ii) possible lack of a liquid secondary market for a futures 
contract and the resulting inability to close a futures position which could 
have an adverse impact on a portfolio's ability to execute futures and 
options strategies. Additional risks associated with options transactions are 
(i) the risk that an option will expire worthless; (ii) the risk that the 
issuer of an over-the- counter option will be unable to fulfill its 
obligation to the portfolio due to bankruptcy or related circumstances; (iii) 
the risk that options may exhibit greater short-term price volatility than 
the underlying security; and (iv) the risk that a portfolio may be forced to 
forego participation in the appreciation of the value of underlying 
securities, futures contracts or currency due to the writing of a call 
option. 

High Yield: High yield securities are generally considered to be corporate 
bonds, preferred stocks, and convertible securities rated Ba through C by 
Moody's or BB through D by Standard & Poor's, and unrated securities 
considered to be of equivalent quality. Securities rated less than Baa by 
Moody's or BBB by Standard & Poor's are classified as non-investment grade 
securities and are commonly referred to as junk bonds or high yield, high 
risk securities. Such securities carry a high degree of risk and are 
considered speculative by the major credit rating agencies. The following are 
excerpts from the Moody's and Standard & Poor's definitions for 
speculative-grade debt obligations: 

    Moody's: Ba-rated bonds have "speculative elements" so their future 
    "cannot be considered assured," and protection of principal and 
    interest is "moderate" and "not well safeguarded during both good 
    and bad times in the future." B-rated bonds "lack characteristics of 
    a desirable investment" and the assurance of interest or principal 
    payments "may be small." Caa-rated bonds are "of poor standing" and 
    "may be in default" or may have "elements of danger with respect to 
    principal or interest." Ca-rated bonds represent obligations which 
    are speculative in a high degree. Such issues are often in default 
    or have other marked shortcomings. C-rated bonds are the "lowest 
    rated" class of bonds, and issues so rated can be regarded as having 
    "extremely poor prospects" of ever attaining any real investment 
    standing. 

- -------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 47
<PAGE>

    Standard & Poor's: BB-rated bonds have "less near-term vulnerability 
    to default" than B- or CCC- rated securities but face "major ongoing 
    uncertainties . . . which may lead to inadequate capacity" to pay 
    interest or principal. B-rated bonds have a "greater vulnerability 
    to default than BB-rated bonds and the ability to pay interest or 
    principal will likely be impaired by adverse business conditions." 
    CCC- rated bonds have a currently identifiable "vulnerability to 
    default" and, without favorable business conditions, will be "unable 
    to repay interest and principal." C The rating C is reserved for 
    income bonds on which "no interest is being paid." D - Debt rated D 
    is in "default", and "payment of interest and/or repayment of 
    principal is in arrears." 

While these securities offer high yields, they also normally carry with them 
a greater degree of risk than securities with higher ratings. Lower-rated 
bonds are considered speculative by traditional investment standards. High 
yield securities may be issued as a consequence of corporate restructuring or 
similar events. Also, high yield securities are often issued by smaller, less 
credit worthy companies, or by highly leveraged (indebted) firms, which are 
generally less able than more established or less leveraged firms to make 
scheduled payments of interest and principal. The price movement of these 
securities is influenced less by changes in interest rates and more by the 
financial and business position of the issuing corporation when compared to 
investment grade bonds. 

The risks posed by securities issued under such circumstances are 
substantial. If a security held by a portfolio is down-graded, the portfolio 
may retain the security. 

Inverse Floaters--Inverse Floating Rate Obligations: are Fixed-Income 
Securities, which have coupon rates that vary inversely at a multiple of a 
designated floating rate, such as LIBOR (London Inter-Bank Offered Rate). Any 
rise in the reference rate of an inverse floater (as a consequence of an 
increase in interest rates) causes a drop in the coupon rate while any drop 
in the reference rate of an inverse floater causes an increase in the coupon 
rate. Inverse floaters may exhibit substantially greater price volatility 
than fixed rate obligations having similar credit quality, redemption 
provisions and maturity, and inverse floater CMOs exhibit greater price 
volatility than the majority of mortgage pass-through securities or CMOs. In 
addition, some inverse floater CMOs exhibit extreme sensitivity to changes in 
prepayments. As a result, the yield to maturity of an inverse floater CMO is 
sensitive not only to changes in interest rates but also to changes in 
prepayment rates on the related underlying mortgage assets. 

Investment Companies: The portfolios are permitted to invest in shares of 
other open-end or closed-end investment companies. The Investment Company Act 
of 1940, as amended, generally prohibits the portfolios from acquiring more 
than 3% of the outstanding voting shares of an investment company and limits 
such investments to no more than 5% of the portfolio's total assets in any 
one investment company and no more than 10% in any combination of investment 
companies. The 1940 Act also prohibits the portfolios from acquiring in the 
aggregate more than 10% of the outstanding voting shares of any registered 
closed-end investment company. 

To the extent a portfolio invests a portion of its assets in Investment 
Companies, those assets will be subject to the expenses of the investment 
company as well as to the expenses of the portfolio itself. The portfolios 
may not purchase shares of any affiliated investment company except as 
permitted by SEC Rule or Order. 

Investment Funds: Some emerging market countries have laws and regulations 
that currently preclude direct foreign investment in the securities of their 
companies. However, indirect foreign investment in the securities of 
companies listed and traded on the stock exchanges in these countries is 
permitted by certain emerging market countries through investment funds. 
Portfolios that may invest in these investment funds are subject to 
applicable law as discussed under Investment Restrictions and will invest in 
such investment funds only where appropriate given that the portfolio's 
shareholders will bear indirectly the layer of expenses of the underlying 
investment funds in addition to their proportionate share of the expenses of 
the portfolio. Under certain circumstances, an investment in an investment 
fund will be subject to the additional limitations that apply to investments 
in Investment Companies.

Investment Grade Securities: are those rated by one or more nationally 
recognized statistical rating organization (NRSRO) in one of the four highest 
rating categories at the time of purchase (e.g. AAA, AA, A or BBB by Standard 
& Poor's Corporation (Standard & Poor's) or Fitch Investors Service, Inc., 
(Fitch) or Aaa, Aa, A or Baa by Moody's Investors Service, Inc. (Moody's). 
Securities rated BBB or Baa represent the lowest of four levels of investment 
grade securities and are regarded as borderline between definitely sound 
obligations and those in which the speculative element begins to predominate. 
Mortgage-backed securities, including mortgage pass-throughs and 
collateralized mortgage obligations (CMOs), deemed investment grade by the 
Adviser, will either carry a guarantee from an agency of the U.S. Government 
or a private issuer of the timely payment of principal and interest (such 
guarantees do not extend to the market value of such securities or the net 
asset value per share of the portfolio) or, in the case of unrated 
securities, be sufficiently seasoned that they are considered by the Adviser 
to be investment grade quality. The Adviser may retain securities if their 
ratings falls below investment grade if it deems retention of the security to 
be in the best interests of the portfolio. Any Portfolio permitted to hold 
Investment Grade Securities may hold unrated securities if the Adviser 
considers the risks involved in owning that security to be equivalent to the 
risks involved in holding an Investment Grade Security. 

Loan Participations: are loans or other direct debt instruments which are 
interests in amounts owed by a corporate, governmental or other borrower to 
another party. They may represent amounts owed to lenders or lending 
syndicates, to suppliers of goods or services (trade claims or other 
receivables), or to other parties. Direct debt instruments involve the risk 
of loss in case of default or insolvency of the borrower. Direct debt 
instruments may offer less legal protection to the portfolio in the event of 
fraud or misrepresentation. In addition, loan participations involve a risk 
of insolvency of the lending bank or other financial intermediary. Direct 
debt instruments may also include standby financing commitments that obligate 
the investing portfolio to supply additional cash to the borrower on demand. 
Loan participations involving Emerging Market Issuers may relate to loans as 
to which there has been or currently exists an event of default or other 
failure to make payment when due, and may represent amounts owed to financial 
institutions that are themselves subject to political and economic risks, 
including the risk of currency devaluation, expropriation, or failure. Such 
loan participations present additional risks of default or loss. 

Mortgage Securities--Mortgage-backed securities represent an ownership 
interest in a pool of residential and commercial mortgage loans. Generally, 
these securities are designed to provide monthly payments of interest and 
principal to the investor. The mortgagee's monthly payments to his/her 
lending institution are passed through to investors such as the portfolio. 
Most issuers or poolers provide guarantees of payments, regardless of whether 
the mortgagor actually makes the payment. The guarantees made by issuers or 
poolers are supported by various forms of credit, collateral, guarantees or 
insurance, including individual loan, title, pool and hazard insurance 
purchased by the issuer. The pools are assembled by various Governmental, 
Government-related and private organizations. Portfolios may invest in 
securities issued or guaranteed by the Government National Mortgage 
Association (GNMA), Federal Home Loan Mortgage Corporation (FHLMC), Federal 
National Mortgage Association (FNMA), private issuers and other government 
agencies. There can be no assurance that the private insurers can meet their 
obligations under the policies. Mortgage-backed securities issued by 
non-agency issuers, whether or not such securities are subject to guarantees, 
may entail greater risk. If there is no guarantee provided by the issuer, 
mortgage- backed securities purchased by the portfolio will be those which at 
time of purchase are rated investment grade by one or more NRSRO, or, if 
unrated, are deemed by the Adviser to be of investment grade quality. 

There are two methods of trading mortgage-backed securities. A specified pool 
transaction is a trade in which the pool number of the security to be 
delivered on the settlement date is known at the time the trade is made. This 
is in contrast with the typical mortgage security transaction, called a TBA 
(to be announced) transaction, in which the type of mortgage securities to be 
delivered is specified at the time of trade but the actual pool numbers of 
the securities that will be delivered are not known at the time of the trade. 
The pool numbers of the pools to be delivered at settlement will be announced 
shortly before settlement takes place. The terms of the TBA trade may be made 
more specific if desired. Generally, agency pass-through mortgage-backed 
securities are traded on a TBA basis. 

A mortgage-backed bond is a collateralized debt security issued by a thrift 
or financial institution. The bondholder has a first priority perfected 
security interest in collateral, usually consisting of agency mortgage 
pass-through securities, although other assets, including U.S. Treasuries 
(including Zero Coupon Treasury Bonds), agencies, cash equivalent securities, 
whole loans and corporate bonds, may qualify. The amount of collateral must 
be continuously maintained at levels from 115% to 150% of the principal 
amount of the bonds issued, depending on the specific issue structure and 
collateral type.

Possible Risks: Due to the possibility that prepayments on home mortgages 
will alter cash flow on mortgage securities, it is not possible to determine 
in advance the actual final maturity date or average life. Like bonds in 
general, mortgage-backed securities will generally decline in price when 
interest rates rise. Due to prepayment risk, rising interest rates also tend 
to discourage refinancings of home mortgages, with the result that the 
average life of mortgage securities held by a portfolio may be lengthened. 
This extension of average life causes the market price of the securities to 
decrease further than if their average lives were fixed. However, when 
interest rates fall, mortgages may not enjoy as large a gain in market value 
due to prepayment risk because additional mortgage prepayments must be 
reinvested at lower interest rates. Faster prepayment will shorten the 
average life and slower prepayments will lengthen it. However, it is possible 
to determine what the range of that movement could be and to calculate the 
effect that it will have on the price of the security. In selecting these 
securities, the Adviser will look for those securities that offer a higher 
yield to compensate for any variation in average maturity. 

Municipals--Municipal Securities: are debt obligations issued by local, state 
and regional governments that provide interest income which is exempt from 
federal income taxes. Municipal securities include both municipal bonds 
(those securities with maturities of five years or more) and municipal notes 
(those with maturities of less than five years). Municipal bonds are issued 
for a wide variety of reasons: to construct public facilities, such as 
airports, highways, bridges, schools, hospitals, mass transportation, 
streets, water and sewer works; to obtain funds for operating expenses; to 
refund outstanding municipal obligations; and to loan funds to various public 
institutions and facilities. Certain industrial development bonds are also 
considered municipal bonds if their interest is exempt from federal income 
tax. Industrial development bonds are issued by or on behalf of public 
authorities to obtain funds for various privately-operated manufacturing 
facilities, housing, sports arenas, convention centers, airports, mass 
transportation systems and water, gas or sewage works. Industrial development 
bonds are ordinarily dependent on the credit quality of a private user, not 
the public issuer. 

General obligation municipal bonds are secured by the issuer's pledge of full 
faith, credit and taxing power. Revenue or special tax bonds are payable from 
the revenues derived from a particular facility or, in some cases, from a 
special excise or other tax, but not from general tax revenue. 

Municipal notes are issued to meet the short-term funding requirements of 
local, regional and state governments. Municipal notes include bond 
anticipation notes, revenue anticipation notes and tax and revenue 
anticipation notes. These are short-term debt obligations issued by state and 
local governments to aid cash flows while waiting for taxes or revenue to be 
collected, at which time the debt is retired. Other types of municipal notes 
in which the portfolio may invest are construction loan notes, short-term 
discount notes, tax-exempt commercial paper, demand notes, and similar 
instruments. Demand notes permit an investor (such as the portfolio) to 
demand from the issuer payment of principal plus accrued interest upon a 
specified number of days' notice. The portfolios eligible to purchase 
municipal bonds may also purchase AMT bonds. AMT bonds are tax-exempt private 
activity bonds issued after August 7, 1986, the proceeds of which are 
directed, at least in part, to private, for-profit organizations. While the 
income from AMT bonds is exempt from regular federal income tax, it is a tax 
preference item in the calculation of the alternative minimum tax. The 
alternative minimum tax is a special separate tax that applies to a limited 
number of taxpayers who have certain adjustments to income or tax preference 
items. 

PA Municipals: are obligations of the Pennsylvania state government, state 
agencies and various local governments, including counties, cities, 
townships, special districts and authorities. In general, the credit quality 
and credit risk of any issuer's debt is contingent upon the state and local 
economy, the health of the issuer's finances, the amount of the issuer's 
debt, the quality of management and the strength of legal provisions in the 
debt document that protect debt holders. Credit risk is usually lower 
wherever the economy is strong, growing and diversified, where financial 
operations are sound and the debt burden is reasonable. 

Concentration of investment in the securities of one state exposes a 
portfolio to greater credit risks than would be present in a nationally 
diversified portfolio of municipal securities. The risks associated with 
investment in the securities of a single state include possible tax changes 
or a deterioration in economic conditions and differing levels of supply and 
demand for the municipal obligations of that state. 

- -------------------------------------------------------------------------------
MAS Funds - 50        Terms in bold type are defined in the Prospectus Glossary

<PAGE>

Debt of Government Agencies, Authorities and Commissions: Certain 
state-created agencies have statutory authorization to incur debt for which 
legislation providing for state appropriations to pay debt service thereon is 
not required. The debt of these agencies is supported by assets of, or 
revenues derived from, the various projects financed; it is not an obligation 
of the Commonwealth. Some of these agencies, however, such as the Delaware 
River Joint Toll Bridge Commission, are indirectly dependent on Commonwealth 
funds through various state- assisted programs. 

Preferred Stock: are non-voting ownership shares in a corporation which pay a 
fixed or variable stream of dividends. 

Repurchase Agreements: are transactions by which a portfolio purchases a 
security and simultaneously commits to resell that security to the seller (a 
bank or securities dealer) at an agreed upon price on an agreed upon date 
(usually within seven days of purchase). The resale price reflects the 
purchase price plus an agreed upon market rate of interest which is unrelated 
to the coupon rate or date of maturity of the purchased security. Such 
agreements permit the portfolio to keep all its assets at work while 
retaining overnight flexibility in pursuit of investments of a longer term 
nature. The Adviser will continually monitor the value of the underlying 
collateral to ensure that its value, including accrued interest, always 
equals or exceeds the repurchase price. 

Pursuant to an order issued by the Securities and Exchange Commission, the 
Fund's portfolios may pool their daily uninvested cash balances in order to 
invest in repurchase agreements on a joint basis. By entering into repurchase 
agreements on a joint basis, it is expected that the portfolios will incur 
lower transaction costs and potentially obtain higher rates of interest on 
such repurchase agreements. Each portfolio's participation in the income from 
jointly purchased repurchase agreements will be based on that portfolio's 
percentage share in the total repurchase agreement. 

Rights: represent a preemptive right of stockholders to purchase additional 
shares of a stock at the time of a new issuance, before the stock is offered 
to the general public, allowing the stockholder to retain the same ownership 
percentage after the new stock offering. 

SMBS--Stripped Mortgage-Backed Securities: are Derivatives in the form of 
multi-class mortgage securities. SMBS may be issued by agencies or 
instrumentalities of the U.S. Government and private originators of, or 
investors in, mortgage loans, including savings and loan associations, 
mortgage banks, commercial banks, investment banks and special purpose 
entities of the foregoing. 

SMBS are usually structured with two classes that receive different 
proportions of the interest and principal distributions on a pool of mortgage 
assets. One type of SMBS will have one class receiving some of the interest 
and most of the principal from the mortgage assets, while the other class 
will receive most of the interest and the remainder of the principal. In some 
cases, one class will receive all of the interest (the IO class), while the 
other class will receive all of the principal (the principal-only or PO 
class). The yield to maturity on IOs and POs is extremely sensitive to the 
rate of principal payments (including prepayments) on the related underlying 
mortgage assets, and a rapid rate of principal payments may have a material 
adverse effect on a portfolio yield to maturity. If the underlying mortgage 
assets experience greater than anticipated prepayments of principal, a 
portfolio may fail to fully recoup its initial investment in these 
securities, even if the security is in one of the highest rating categories. 

Although SMBS are purchased and sold by institutional investors through 
several investment banking firms acting as brokers or dealers, these 
securities were only recently developed. As a result, established trading 
markets have not yet developed and, accordingly, certain of these securities 
may be deemed illiquid and subject to a portfolio's limitations on investment 
in illiquid securities. 

Structured Investments: are Derivatives in the form of a unit or units 
representing an undivided interest(s) in assets held in a trust that is not 
an investment company as defined in the Investment Company Act of 1940. A 
trust unit pays a return based on the total return of securities and other 
investments held by the trust and the trust may enter into one or more Swaps 
to achieve its objective. For example, a trust may purchase a basket of 
securities and 

- -------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 51
<PAGE>

agree to exchange the return generated by those securities for the return 
generated by another basket or index of securities. A portfolio will purchase 
Structured Investments in trusts that engage in such Swaps only where the 
counterparties are approved by MAS in accordance with credit-risk guidelines 
established by the Board of Trustees. 

Structured Notes: are Derivatives on which the amount of principal repayment 
and or interest payments is based upon the movement of one or more factors. 
These factors include, but are not limited to, currency exchange rates, 
interest rates (such as the prime lending rate and LIBOR) and stock indices 
such as the S&P 500 Index. In some cases, the impact of the movements of 
these factors may increase or decrease through the use of multipliers or 
deflators. The use of Structured Notes allows a portfolio to tailor its 
investments to the specific risks and returns the Adviser wishes to accept 
while avoiding or reducing certain other risks. 

Swaps--Swap Contracts: are Derivatives in the form of a contract or other 
similar instrument which is an agreement to exchange the return generated by 
one instrument for the return generated by another instrument. The payment 
streams are calculated by reference to a specified index and agreed upon 
notional amount. The term specified index includes, but is not limited to, 
currencies, fixed interest rates, prices and total return on interest rate 
indices, fixed-income indices, stock indices and commodity indices (as well 
as amounts derived from arithmetic operations on these indices). For example, 
a portfolio may agree to swap the return generated by a fixed-income index 
for the return generated by a second fixed-income index. The currency swaps 
in which the portfolios may enter will generally involve an agreement to pay 
interest streams in one currency based on a specified index in exchange for 
receiving interest streams denominated in another currency. Such swaps may 
involve initial and final exchanges that correspond to the agreed upon 
national amount. 

A portfolio will usually enter into swaps on a net basis, i.e., the two 
return streams are netted out in a cash settlement on the payment date or 
dates specified in the instrument, with a portfolio receiving or paying, as 
the case may be, only the net amount of the two returns. A portfolio's 
obligations under a swap agreement will be accrued daily (offset against any 
amounts owing to the portfolio) and any accrued but unpaid net amounts owed 
to a swap counterparty will be covered by the maintenance of a segregated 
account consisting of cash or liquid securities. A portfolio will not enter 
into any swap agreement unless the counterparty meets the rating requirements 
set forth in guidelines established by the Fund's Board of Trustees. 

Possible Risks: Interest rate and total rate of return swaps do not involve 
the delivery of securities, other underlying assets, or principal. 
Accordingly, the risk of loss with respect to interest rate and total rate of 
return swaps is limited to the net amount of interest payments that a 
portfolio is contractually obligated to make. If the other party to an 
interest rate or total rate of return swap defaults, a portfolio's risk of 
loss consists of the net amount of interest payments that a portfolio is 
contractually entitled to receive. In contrast, currency swaps usually 
involve the delivery of the entire principal value of one designated currency 
in exchange for the other designated currency. Therefore, the entire 
principal value of a currency swap is subject to the risk that the other 
party to the swap will default on its contractual delivery obligations. If 
there is a default by the counterparty, a portfolio may have contractual 
remedies pursuant to the agreements related to the transaction. The swap 
market has grown substantially in recent years with a large number of banks 
and investment banking firms acting both as principals and as agents 
utilizing standardized swap documentation. As a result, the swap market has 
become relatively liquid. Swaps that include caps, floors, and collars are 
more recent innovations for which standardized documentation has not yet been 
fully developed and, accordingly, they are less liquid than swaps. 

The use of swaps is a highly specialized activity which involves investment 
techniques and risks different from those associated with ordinary portfolio 
securities transactions. If the Adviser is incorrect in its forecasts of 
market values, interest rates, and currency exchange rates, the investment 
performance of the portfolios would be less favorable than it would have been 
if this investment technique were not used. 

Taxable Investments: comprise Fixed-Income Securities and other instruments 
which pay income that is not exempt from taxation. Investors may be liable 
for tax on the income distributed as a result of the portfolio holding 
taxable investments. In this event, shareholders will receive an IRS form 
1099 disclosing the taxable income paid for a calendar year.

MAS Funds - 52        Terms in bold type are defined in the Prospectus Glossary

<PAGE>

U.S. Governments--U.S. Treasury securities: are Fixed-Income Securities which 
are backed by the full faith and credit of the U.S. Government as to the 
payment of both principal and interest. 

Warrants: are options issued by a corporation which give the holder the 
option to purchase stock. 

When-Issued Securities: are securities purchased at a certain price even 
though the securities may not be delivered for up to 90 days. No payment or 
delivery is made by a portfolio in a when-issued transaction until the 
portfolio receives payment or delivery from the other party to the 
transaction. Although a portfolio receives no income from the above described 
securities prior to delivery, the market value of such securities is still 
subject to change. As a consequence, it is possible that the market price of 
the securities at the time of delivery may be higher or lower than the 
purchase price. A portfolio will maintain with the custodian a separate 
account with a segregated account consisting of cash or liquid securities in 
an amount at least equal to these commitments. 

Zero Coupons--Zero Coupon Obligations: are Fixed-Income Securities that do 
not make regular interest payments. Instead, zero coupon obligations are sold 
at substantial discounts from their face value. The difference between a zero 
coupon obligation's issue or purchase price and its face value represents the 
imputed interest an investor will earn if the obligation is held until 
maturity. Zero coupon obligations may offer investors the opportunity to earn 
higher yields than those available on ordinary interest-paying obligations of 
similar credit quality and maturity. However, zero coupon obligation prices 
may also exhibit greater price volatility than ordinary fixed- income 
securities because of the manner in which their principal and interest are 
returned to the investor. 

GENERAL SHAREHOLDER INFORMATION 

                              PURCHASE OF SHARES 

Institutional Class Shares are available to clients of the Adviser with 
combined investments of $5,000,000 and Shareholder Organizations who have a 
contractual arrangement with the Fund, including institutions such as trusts, 
foundations or broker-dealers purchasing for the accounts of others. 

Institutional Class Shares of each portfolio except for the Cash Reserves 
Portfolio may be purchased at the net asset value per share next determined 
after receipt of the purchase order. Such portfolios determine net asset 
value as described under Other Information-Valuation of Shares each day that 
the portfolios are open for business. See Other Information-Closed Holidays 
and Valuation of Shares. 

The Cash Reserves Portfolio declares dividends daily and, therefore, at the 
time of a purchase must have funds immediately available for investment. As a 
result, payment for the purchase of shares must be in the form of Federal 
Funds (monies credited to the portfolio's Custodian by a Federal Reserve 
Bank) before they can be accepted by the portfolio. The portfolio is credited 
with Federal Funds on the same day if the investment is made by Federal 
Funds. Institutional Class Shares of the Cash Reserves Portfolio may be 
purchased at the net asset value next determined after an order is received 
by the portfolio and Federal Funds are received by the Custodian. The Cash 
Reserves Portfolio determines net asset value as of 12:00 noon (Eastern Time) 
each day that the portfolios are open for business. See Other 
Information-Closed Holidays and Valuation of Shares. 

Initial Purchase by Mail: Subject to acceptance by the Fund, an account may 
be opened by contacting MAS Funds' Client Services Group at 1-800-354-8185, 
One Tower Bridge, Suite 1150, P.O. Box 868, West Conshohocken, Pennsylvania 
19428-0868. 

Subject to acceptance by the Fund, payment for the purchase of shares 
received by mail will be credited at the net asset value per share of the 
portfolio next determined after receipt. Such payment need not be converted 
into Federal Funds (monies credited to the Fund's Custodian Bank by a Federal 
Reserve Bank) before acceptance by the Fund, except for the Cash Reserves 
Portfolio. Purchases made by check in the Cash Reserves Portfolio are ordi- 

- -------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 53
<PAGE>

narily credited at the net asset value per share determined two business days 
after receipt of the check by the Fund. Please note that purchases made by 
check in any portfolio are not permitted to be redeemed until payment of the 
purchase has been collected, which may take up to eight business days after 
purchase. Shareholders can avoid this delay by purchasing shares by wire. 

Initial Purchase by Wire: Subject to acceptance by the Fund, Institutional 
Class Shares of each portfolio may also be purchased by wiring Federal Funds 
to the Fund's Custodian Bank, The Chase Manhattan Bank, N.A. (see 
instructions below). A completed Account Registration Form should be 
forwarded to MAS Funds' Client Services Group in advance of the wire. For all 
portfolios (except the Cash Reserves Portfolio), notification must be given 
to MAS Funds' Client Services Group at 1-800-354-8185 prior to the 
determination of net asset value. Institutional Class Shares will be 
purchased at the net asset value per share next determined after receipt of 
the purchase order. (Prior notification must also be received from investors 
with existing accounts.) Instruct your bank to send a Federal Funds Wire in a 
specified amount to the Fund's Custodian Bank using the following wiring 
instructions: 
                             The Chase Manhattan Bank 
                             1 Chase Manhattan Plaza

                             Attn: MAS Funds 
                             Ref: (Portfolio Name, Account Number, Account Name)

Purchases in the Cash Reserves Portfolio may also be made by Federal Funds 
wire to the Fund's Custodian. If the portfolio receives notification of an 
order prior to 12:00 noon (Eastern Time) and funds are received by the 
Custodian the same day, purchases of portfolio shares will become effective 
and begin to earn income on that business day. Orders received after 12:00 
noon (Eastern Time) will be effective on the next business day upon receipt 
of funds. Federal Funds purchases will be accepted only on a day on which the 
portfolio is open for business. See Other Information-Closed Holidays. 

Additional Investments: Additional investments of Institutional Class Shares 
at net asset value may be made at any time (minimum investment $1,000) by 
mailing a check (payable to MAS Funds) to MAS Funds' Client Services Group at 
the address noted under Initial Investments by Mail or by wiring Federal 
Funds to the Custodian Bank as outlined above. Shares will be purchased at 
the net asset value per share next determined after receipt of the purchase 
order. For all portfolios, notification must be given to MAS Fund's Client 
Services Group at 1-800- 354-8185 prior to the determination of net asset 
value. For the Cash Reserves Portfolio, notification of a Federal Funds wire 
must be received by 12:00 noon (Eastern Time). Purchases made by check in the 
Cash Reserves Portfolio are ordinarily credited at the net asset value per 
share determined two business days after receipt of the check by the Fund. 

Other Purchase Information: The Fund reserves the right, in its sole 
discretion, to suspend the offering of Institutional Class Shares of any of 
its portfolios or to reject any purchase orders when, in the judgment of 
management, such suspension or rejection is in the best interest of the Fund. 
The Fund also reserves the right, in its sole discretion, to waive the 
minimum initial and subsequent investment amounts. 

Purchases of a portfolio's Institutional Class Shares will be made in full 
and fractional shares of the portfolio calculated to three decimal places. In 
the interest of economy and convenience, certificates for shares will not be 
issued except at the written request of the shareholder. Certificates for 
fractional shares, however, will not be issued. 

Institutional Class Shares of the Fund's portfolios are also sold to 
corporations or other institutions such as trusts, foundations or 
broker-dealers purchasing for the accounts of others (Shareholder 
Organizations). Investors purchasing and redeeming shares of the portfolios 
through a Shareholder Organization may be charged a transaction-based fee or 
other fee for the services of such organization. Each Shareholder 
Organization is responsible for transmitting to its customers a schedule of 
any such fees and information regarding any additional or different 
conditions regarding purchases and redemptions. Customers of Shareholder 
Organizations should read this Prospectus in light of the terms governing 
accounts with their organization. The Fund does not pay compensation to or 
receive compensation from Shareholder Organizations for the sale of 
Institutional Class Shares.

                             REDEMPTION OF SHARES 

Institutional Class Shares of each portfolio may be redeemed by mail, or, if 
authorized, by telephone. No charge is made for redemptions. The value of 
Institutional Class Shares redeemed may be more or less than the purchase 
price, depending on the net asset value at the time of redemption which is 
based on the market value of the investment securities held by the portfolio. 
See other Information-Closed Holidays and Valuation of Shares. 

By Mail: Each portfolio will redeem Institutional Class Shares at the net 
asset value next determined after the request is received in good order. 
Requests should be addressed to MAS Funds: c/o the Client Services Group, One 
Tower Bridge, Suite 1150, P.O. Box 868, West Conshohocken, PA 19428-0868. 

To be in good order, redemption requests must include the following 
documentation: 

(a) The share certificates, if issued; 

(b) A letter of instruction, if required, or a stock assignment specifying 
the number of shares or dollar amount to be redeemed, signed by all 
registered owners of the shares in the exact names in which the shares are 
registered; 

(c) Any required signature guarantees (see Signature Guarantees); and 

(d) Other supporting legal documents, if required, in the case of estates, 
trusts, guardianships, custodianships, corporations, pension and profit 
sharing plans and other organizations. 

Signature Guarantees: To protect your account, the Fund and the Administrator 
from fraud, signature guarantees are required to enable the Fund to verify 
the identity of the person who has authorized a redemption from an account. 
Signature guarantees are required for (1) redemptions where the proceeds are 
to be sent to someone other than the registered shareholder(s) and the 
registered address, and (2) share transfer requests. Please contact MAS 
Funds' Client Services Group for further details. 

By Telephone: Provided the Telephone Redemption Option has been authorized by 
the shareholder on the Account Registration Form, a redemption of shares may 
be requested by calling MAS Funds' Client Services Group and requesting that 
the redemption proceeds be mailed to the primary registration address or 
wired per the authorized instructions. Shares cannot be redeemed by telephone 
if share certificates are held for those shares. 

By Facsimile: Written requests in good order (see above) for redemptions, 
exchanges, and transfers may be forwarded to the Fund via facsimile. All 
requests sent to the Fund via facsimile must be followed by a telephone call 
to MAS Funds' Client Services Group to ensure that the instructions have been 
properly received by the Fund. The original request must be promptly mailed 
to MAS Funds, c/o Client Services Group, One Tower Bridge, Suite 1150, P. O. 
Box 868, West Conshohocken, PA 19428-0868. 

Neither the Distributor nor the Fund will be responsible for any loss, 
liability, cost, or expense for acting upon facsimile instructions or upon 
telephone instructions that they reasonably believe to be genuine. In order 
to confirm that telephone instructions in connection with redemptions are 
genuine, the Fund and Distributor will provide written confirmation of 
transactions initiated by telephone. 

Payment of the redemption proceeds will ordinarily be made within three 
business days after receipt of an order for a redemption. The Fund may 
suspend the right of redemption or postpone the date of redemption at times 
when the NYSE, the Custodian, or the Fund is closed (see Other 
Information-Closed Holidays) or under any emergency circumstances as 
determined by the Securities and Exchange Commission.

<PAGE>

If the Board of Trustees determines that it would be detrimental to the best 
interests of the remaining shareholders of the Fund to make payment wholly or 
partly in cash, the Fund may pay the redemption proceeds in whole or in part 
by a distribution in-kind of readily marketable securities held by a 
portfolio in lieu of cash in conformity with applicable rules of the 
Securities and Exchange Commission. Investors may incur brokerage charges on 
the sale of portfolio securities received in such payments of redemptions. 

                             SHAREHOLDER SERVICES 

Exchange Privilege: Each portfolio's Institutional Class Shares may be 
exchanged for shares of the Fund's other portfolios (except the Small Cap 
Value Portfolio which is currently not accepting new investors) based on the 
respective net asset values of the shares involved. The exchange privilege is 
only available, however, with respect to portfolios that are registered for 
sale in a shareholder's state of residence. There are no exchange fees. 
Exchange requests should be sent to MAS Funds, c/o Client Services Group, One 
Tower Bridge, Suite 1150, P.O. Box 868, West Conshohocken, PA 19428-0868, 
1-800-354-8185. 

Because an exchange of shares amounts to a redemption from one portfolio and 
purchase of shares of another portfolio, the above information regarding 
purchase and redemption of shares applies to exchanges. Shareholders should 
note that an exchange between portfolios is considered a sale and purchase of 
shares for tax purposes. 

The officers of the Fund reserve the right not to accept any request for an 
exchange when, in their opinion, the exchange privilege is being used as a 
tool for market timing. The Fund reserves the right to change the terms or 
conditions of the exchange privilege discussed herein upon sixty days' 
notice. 

Transfer of Registration: The registration of Fund shares may be transferred 
by writing to MAS Funds, c/o Client Services Group, One Tower Bridge, Suite 
1150, P.O. Box 868, West Conshohocken, PA 19428-0868. As in the case of 
redemptions, the written request must be received in good order as defined 
above. 

                             VALUATION OF SHARES 

Equity, Value, Small Cap Value, Mid Cap Value, Growth, Mid Cap Growth, 
International Equity and Emerging Markets Portfolios: 

Net asset value per share of each class is determined by dividing the total 
market value of each portfolio's investments and other assets, less any 
liabilities, by the total outstanding shares of that portfolio. Net asset 
value per share is determined as of the close of the NYSE (normally 4:00 p.m. 
Eastern Time) on each day the portfolio is open for business (See Other 
Information-Closed Holidays). Equity Securities listed on a U.S. securities 
exchange or NASDAQ for which market quotations are available are valued at 
the last quoted sale price on the day the valuation is made. Price 
information on listed Equity Securities is taken from the exchange where the 
security is primarily traded. Equity Securities listed on a foreign exchange 
are valued at the latest quoted sales price available before the time when 
assets are valued. For purposes of net asset value per share, all assets and 
liabilities initially expressed in foreign currencies are converted into U.S. 
dollars at the bid price of such currencies against U.S. dollars. Unlisted 
Equity Securities and listed U.S. Equity Securities not traded on the 
valuation date for which market quotations are readily available are valued 
at the mean of the most recent quoted bid and asked price. The value of other 
assets and securities for which no quotations are readily available 
(including restricted securities) are determined in good faith at fair value 
using methods approved by the Trustees. 

Domestic Fixed Income, Fixed Income, Fixed Income Portfolio II, Special 
Purpose Fixed Income, High Yield, Limited Duration, Intermediate Duration, 
Mortgage-Backed Securities, Global Fixed Income, International Fixed Income, 
Municipal and PA Municipal Portfolios: 

Net asset value per share is computed by dividing the total value of the 
investments and other assets of the portfolio, less any liabilities, by the 
total outstanding shares of the portfolio. The net asset value per share is 
determined as of one hour after the close of the bond markets (normally 4:00 
p.m. Eastern Time) on each day the portfolio is 

- -------------------------------------------------------------------------------
MAS Funds - 56        Terms in bold type are defined in the Prospectus Glossary

<PAGE>

open for business (See Other Information-Closed Holidays). Bonds and other 
Fixed-Income Securities listed on a foreign exchange are valued at the latest 
quoted sales price available before the time when assets are valued. For 
purposes of net asset value per share, all assets and liabilities initially 
expressed in foreign currencies will be converted into U.S. dollars at the 
bid price of such currencies against U.S. dollars. 

Net asset value includes interest on bonds and other Fixed-Income Securities 
which is accrued daily. Bonds and other Fixed-Income Securities which are 
traded over the counter and on an exchange will be valued according to the 
broadest and most representative market, and it is expected that for bonds 
and other Fixed-Income Securities this ordinarily will be the 
over-the-counter market. 

However, bonds and other Fixed-Income Securities may be valued on the basis 
of prices provided by a pricing service when such prices are believed to 
reflect the fair market value of such securities. The prices provided by a 
pricing service are determined without regard to bid or last sale prices but 
take into account institutional size trading in similar groups of securities 
and any developments related to specific securities. Bonds and other Fixed- 
Income Securities not priced in this manner are valued at the most recent 
quoted bid price, or when stock exchange valuations are used, at the latest 
quoted sale price on the day of valuation. If there is no such reported sale, 
the latest quoted bid price will be used. Securities purchased with remaining 
maturities of 60 days or less are valued at amortized cost when the Board of 
Trustees determines that amortized cost reflects fair value. In the event 
that amortized cost does not approximate market, market prices as determined 
above will be used. Other assets and securities, for which no quotations are 
readily available (including restricted securities), will be valued in good 
faith at fair value using methods approved by the Board of Trustees. 

Balanced and Multi-Asset-Class Portfolios: Net asset value per share is 
computed by dividing the total value of the investments and other assets of 
the portfolio, less any liabilities, by the total outstanding shares of the 
portfolio. The net asset value per share of the Balanced and 
Multi-Asset-Class Portfolios is determined as of the later of the close of 
the NYSE or one hour after the close of the bond markets on each day the 
portfolios are open for business. Equity, fixed-income and other securities 
held by the portfolios will be valued using the policies described above. 

Cash Reserves Portfolio: The net asset value per share of the Cash Reserves 
Portfolio is calculated daily as of 12:00 noon (Eastern Time) on each day 
that the portfolio is open for business (See Other Information-Closed 
Holidays). The portfolio determines its net asset value per share by 
subtracting the portfolio's liabilities (including accrued expenses and 
dividends payable) from the total value of the portfolio's investments and 
other assets and dividing the result by the total outstanding shares of the 
portfolio. 

For the purpose of calculating the portfolio's net asset value per share, 
securities are valued by the amortized cost method of valuation, which does 
not take into account unrealized gains or losses. This involves valuing an 
instrument at its cost and thereafter assuming a constant amortization to 
maturity of any discount or premium, regardless of the impact of fluctuating 
interest rates on the market value of the instrument. While this method 
provides certainty in valuation, it may result in periods during which value 
based on amortized cost is higher or lower than the price the portfolio would 
receive if it sold the instrument. 

The use of amortized cost and the maintenance of the portfolio's per share 
net asset value at $1.00 is based on its election to operate under the 
provisions of Rule 2a-7 under the Investment Company Act of 1940, as amended. 
As conditions of operating under Rule 2a-7, the portfolio must maintain a 
dollar-weighted average portfolio maturity of 90 days or less, purchase only 
instruments having remaining maturities of thirteen months or less and invest 
only in U.S. dollar-denominated securities which are determined by the 
Trustees to present minimal credit risks and which are of eligible quality as 
determined under the rule. 

The Trustees have also agreed to establish procedures reasonably designed, 
taking into account current market conditions and the portfolio's investment 
objective, to stabilize the net asset value per share as computed for the 
purposes of sales and redemptions at $1.00. These procedures include periodic 
review, as the Trustees deem appropriate and at such intervals as are 
reasonable in light of current market conditions, of the relationship between 
the amortized cost value per share and a net asset value per share based upon 
available indications of market value. In such a review, investments for 
which market quotations are readily available are valued at the most recent 
bid price 

- -------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 57
<PAGE>

or quoted yield equivalent for such securities or for securities of 
comparable maturity, quality and type as obtained from one or more of the 
major market makers for the securities to be valued. Other investments and 
assets are valued at fair value, as determined in good faith by the Trustees. 

In the event of a deviation of over 1/2 of 1% between a portfolio's net asset 
value based upon available market quotations or market equivalents and $1.00 
per share based on amortized cost, the Trustees will promptly consider what 
action, if any, should be taken. The Trustees will also take such action as 
they deem appropriate to eliminate or to reduce to the extent reasonably 
practicable any material dilution or other unfair results which might arise 
from differences between the two. Such action may include redeeming shares in 
kind, selling instruments prior to maturity to realize capital gains or 
losses or to shorten average maturity, withholding dividends, paying 
distributions from capital or capital gains, or utilizing a net asset value 
per share not equal to $1.00 based upon available market quotations. 

DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES: Dividends and Capital Gains 
Distributions: The Fund maintains different dividend and capital gain 
distribution policies for each portfolio. These are: 

o  The Equity, Value, Growth, Fixed Income, Fixed Income Portfolio II, 
   Special Purpose Fixed Income, High Yield, Limited Duration, Intermediate 
   Duration, Mortgage-Backed Securities, Balanced, Multi-Asset-Class, Global 
   Fixed Income, International Fixed Income and Domestic Fixed Income 
   Portfolios normally distribute substantially all of their net investment 
   income to shareholders in the form of quarterly dividends. 

o  The International Equity, Small Cap Value, Mid Cap Value, Mid Cap Growth 
   and Emerging Markets Portfolios normally distribute substantially all of 
   their net investment income in the form of annual dividends. 

o  The Municipal and the PA Municipal Portfolios normally distribute 
   substantially all of their net investment income in the form of monthly 
   dividends. 

o  The Cash Reserves Portfolio declares dividends daily and normally 
   distributes substantially all of its investment income in the form of 
   monthly dividends. 

If any portfolio does not have income available to distribute, as determined 
in compliance with the appropriate tax laws, no distribution will be made. 

If any net capital gains are realized from the sale of underlying securities, 
the portfolios normally distribute such gains with the last dividend for the 
calendar year. 

All dividends and capital gains distributions are automatically paid in 
additional shares of the portfolio unless the shareholder elects otherwise. 
Such election must be made in writing to the Fund and may be made on the 
Account Registration Form. 

In all portfolios except the Cash Reserves Portfolio, undistributed net 
investment income is included in the portfolio's net assets for the purpose 
of calculating net asset value per share. Therefore, on the ex-dividend date, 
the net asset value per share excludes the dividend (i.e., is reduced by the 
per share amount of the dividend). Dividends paid shortly after the purchase 
of shares by an investor, although in effect a return of capital, are taxable 
as ordinary income. 

Certain Mortgage Securities may provide for periodic or unscheduled payments 
of principal and interest as the mortgages underlying the securities are paid 
or prepaid. However, such principal payments (not otherwise characterized as 
ordinary discount income or bond premium expense) will not normally be 
considered as income to the portfolio and therefore will not be distributed 
as dividends. Rather, these payments on mortgage-backed securities will be 
reinvested on behalf of the shareholders by the portfolio in accordance with 
its investment objectives and policies. 

- -------------------------------------------------------------------------------
MAS Funds - 58        Terms in bold type are defined in the Prospectus Glossary

<PAGE>

Special Considerations for the Cash Reserves Portfolio: Net investment income 
is computed and dividends declared as of 12:00 noon (Eastern Time), on each 
day. Such dividends are payable to Cash Reserves Portfolio shareholders of 
record as of 12:00 noon (Eastern Time) on that day, if the portfolio is open 
for business. Shareholders who redeem prior to 12:00 noon (Eastern Time) are 
not entitled to dividends for that day. Dividends declared for Saturdays, 
Sundays and holidays are payable to shareholders of record as of 12:00 noon 
(Eastern Time) on the preceding business day on which the portfolio was open 
for business. 

For the purpose of calculating dividends, net income shall consist of 
interest earned, including any discount or premium ratably amortized to the 
date of maturity, minus estimated expenses of the portfolio. 

Net realized short-term capital gains, if any, of the Cash Reserves Portfolio 
will be distributed whenever the Trustees determine that such distributions 
would be in the best interest of shareholders, but at least once a year. The 
portfolio does not expect to realize any long-term capital gains. Should any 
such gains be realized, they will be distributed annually. 

Federal Taxes: Each portfolio of the Fund intends to qualify for taxation as 
a regulated investment company under the Code so that each portfolio will not 
be subject to Federal income tax to the extent it distributes its income to 
its shareholders. Dividends, either in cash or reinvested in shares, paid by 
a portfolio from net investment income will be taxable to shareholders as 
ordinary income, except for the Municipal and PA Municipal Portfolios (see 
Special Tax Considerations for the Municipal and PA Municipal Portfolios). In 
the case of the Equity, Value, Small Cap Value, Mid Cap Growth, Growth, 
Balanced, Multi-Asset-Class and Mid Cap Value Portfolios, such dividends will 
generally qualify in part for the dividends received deduction for 
corporations, but the portion of the dividends so qualified depends on the 
aggregate taxable qualifying dividend income received by each portfolio from 
domestic (U.S.) sources. The Fund will send each shareholder a statement each 
year indicating the amount of the dividend income which qualifies for such 
treatment. 

Whether paid in cash or additional shares of a portfolio, and regardless of 
the length of time the shares in such portfolio have been owned by the 
shareholder, distributions from long-term capital gains are taxable to 
shareholders as such, but are not eligible for the dividends received 
deduction for corporations. Shareholders are notified annually by the Fund as 
to Federal tax status of dividends and distributions paid by a portfolio. 
Such dividends and distributions may also be subject to state and local 
taxes. 

Exchanges and redemptions of shares in a portfolio are taxable events for 
Federal income tax purposes. Individual shareholders may also be subject to 
state and municipal taxes on such exchanges and redemptions. 

Each portfolio intends to declare and pay dividends and capital gain 
distributions so as to avoid imposition of the Federal excise tax. To do so, 
each portfolio expects to distribute an amount at least equal to (i) 98% of 
its calendar year ordinary income, (ii) 98% of its capital gains net income 
(the excess of short and long-term capital gain over short and long-term 
capital loss) for the one-year period ending October 31st, and (iii) 100% of 
any undistributed ordinary and capital gain net income from the prior year. 
Dividends declared in December by a portfolio will be deemed to have been 
paid by such portfolio and received by shareholders on the record date 
provided that the dividends are paid before February 1 of the following year. 

The Fund is required by Federal law to withhold 31% of reportable payments 
(which may include dividends, capital gains distributions, and redemptions) 
paid to shareholders who have not complied with IRS regulations. In order to 
avoid this withholding requirement, you must certify on the Account 
Registration Form that your Social Security or Taxpayer Identification Number 
provided is correct and that you are not currently subject to back-up 
withholding, or that you are exempt from back-up withholding. 

Foreign Income Taxes: Investment income received by the portfolios from 
sources within foreign countries may be subject to foreign income taxes 
withheld at the source. The U.S. has entered into Tax Treaties with many for-

- -------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 59
<PAGE>

eign countries which entitle these portfolios to a reduced rate of tax or 
exemption from tax on such income. It is impossible to determine the 
effective rate of foreign tax in advance since the amount of the portfolios' 
assets to be invested within various countries is not known. The portfolios 
intend to operate so as to qualify for treaty reduced rates of tax where 
applicable. 

The International Equity, Emerging Markets, Global Fixed Income and 
International Fixed Income Portfolios may file an election with the Internal 
Revenue Service to pass through to the portfolio's shareholders the amount of 
foreign income taxes paid by the portfolio, but may do so only if more than 
50% of the value of the total assets of the portfolio at the end of the 
fiscal year is represented by foreign securities. These portfolios will make 
such an election only if they deem it to be in the best interests of their 
shareholders. 

If this election is made, shareholders of the portfolio will be required to: 
(i) include in gross income, even though not actually received, their 
respective pro rata share of foreign taxes paid by the portfolio; (ii) treat 
their pro rata share of foreign taxes as paid by them; and (iii) either 
deduct their pro rata share of foreign taxes in computing their taxable 
income or use it within the limitations set forth in the Internal Revenue 
Code as a foreign tax credit against U.S. income taxes (but not both). No 
deduction for foreign taxes may be claimed by a shareholder who does not 
itemize deductions. 

Each shareholder of the portfolio will be notified within 60 days after the 
close of each taxable (fiscal) year of the Fund if the foreign taxes paid by 
the portfolio will pass through for that year, and, if so, the amount of each 
shareholder's pro rata share (by country) of (i) the foreign taxes paid, and 
(ii) the portfolio's gross income from foreign sources. Shareholders who are 
not liable for Federal income taxes, such as retirement plans qualified under 
Section 401 of the Internal Revenue Code, will not be affected by any such 
"pass through" of foreign tax credits. 

State and Local Taxes: The Fund is formed as a Pennsylvania Business Trust 
and therefore is not liable, under current law, for any corporate income or 
franchise tax of the Commonwealth of Pennsylvania. The Fund will provide 
Pennsylvania taxable values on a per share basis upon request. 

Special Tax Considerations for the Municipal and PA Municipal 
Portfolios: These portfolios intend to invest a sufficient portion of their 
assets in municipal bonds and notes so that each will qualify to pay 
exempt-interest dividends to shareholders. Such exempt-interest dividends are 
excluded from a shareholder's gross income for Federal personal income tax 
purposes. Tax-exempt dividends received from the Municipal and PA Municipal 
Portfolios may be subject to state and local taxes. However, some states 
allow shareholders to exclude that portion of a portfolio's tax-exempt income 
which is attributable to municipal securities issued within the shareholder's 
state of residence. Furthermore, the PA Municipal Portfolio invests at least 
65% of its assets in PA Municipals. As a result, the income of the portfolio 
that is derived from PA Municipals and U.S. Governments will not be subject 
to the Pennsylvania personal income tax or to the Philadelphia School 
District investment net income tax. Distributions by the PA Municipal 
Portfolio to a Pennsylvania resident that are attributable to most other 
sources may be subject to the Pennsylvania personal income tax and (for 
residents of Philadelphia) to the Philadelphia School District investment net 
income tax. To the extent, if any, that dividends paid to shareholders of the 
Municipal and PA Municipal Portfolios are derived from taxable interest or 
long-term or short-term capital gains, such dividends will be subject to 
Federal personal income tax (whether such dividends are paid in cash or in 
additional shares) and may also be subject to state and local taxes. In 
addition, the Municipal and PA Municipal Portfolios may invest in private 
activity municipal securities, the interest on which is subject to the 
Federal alternative minimum tax for individuals (AMT bonds). To the extent 
that the portfolios invest in AMT bonds, individuals who are subject to the 
AMT will be required to report a portion of dividends as a tax preference 
item in determining their federal taxes. A shareholder may lose the tax 
exempt status of the accrual income of these portfolios if they redeem their 
shares before a dividend has been declared. 

TRUSTEES OF THE TRUST: The affairs of the Trust are supervised by the 
Trustees under the laws governing business trusts in the Commonwealth of 
Pennsylvania. The Trustees have approved contracts under which, as described 
above, certain companies provide essential management, administrative and 
shareholder services to the Trust.

INVESTMENT ADVISER: The Investment Adviser to the Fund, Miller Anderson & 
Sherrerd, LLP (the Adviser), is a Pennsylvania limited liability partnership 
founded in 1969 and is located at One Tower Bridge, West Conshohocken, PA 
19428. Miller Anderson & Sherrerd, LLP is an Equal Opportunity/Affirmative 
Action Employer. The Adviser provides investment services to employee benefit 
plans, endowment funds, foundations and other institutional investors and as 
of the date of this prospectus had in excess of $35 billion in assets under 
management. On January 3, 1996, Morgan Stanley Group Inc. acquired Miller 
Anderson & Sherrerd, LLP (the "Adviser") in a transaction in which Morgan 
Stanley Asset Management Holdings Inc., an indirect wholly owned subsidiary 
of Morgan Stanley Group Inc., became the sole general partner of the Adviser. 
Morgan Stanley Asset Management Holdings Inc. and two other wholly owned 
subsidiaries of Morgan Stanley Group Inc. became the limited partners of the 
Adviser. In connection with this transaction, the Adviser entered into a new 
Investment Management Agreement ("Agreement") with MAS Funds dated as of 
January 3, 1996, which Agreement was approved by the shareholders of each 
Portfolio at a special meeting held on October 6, 1995. The Adviser will 
retain its name and remain at its current location, One Tower Bridge, West 
Conshohocken, PA 19428. The Adviser will continue to provide investment 
counseling services to employee benefit plans, endowments, foundations, and 
other institutional investors. 

Under the Agreement with the Fund, the Adviser, subject to the control and 
supervision of the Fund's Board of Trustees and in conformance with the 
stated investment objectives and policies of each portfolio of the Fund, 
manages the investment and reinvestment of the assets of each portfolio of 
the Fund. In this regard, it is the responsibility of the Adviser to make 
investment decisions for the Fund's portfolios and to place each portfolio's 
purchase and sales orders. As compensation for the services rendered by the 
Adviser under the Agreement, each portfolio pays the Adviser an advisory fee 
calculated by applying a quarterly rate, based on the following annual 
percentage rates, to the portfolio's average daily net assets for the 
quarter:

Richard B. Worley, Portfolio Manager, joined MAS in 1978. He assumed 
responsibility for the Fixed Income Portfolio in 1984, the Domestic Fixed 
Income Portfolio in 1987, the Fixed Income Portfolio II in 1990, the Balanced 
and Special Purpose Fixed Income Portfolios in 1992, the Global Fixed Income 
and International Fixed Income Portfolios in 1993 and the Multi-Asset-Class 
Portfolio in 1994. 

ADMINISTRATIVE SERVICES: MAS serves as Administrator to the Fund pursuant to 
an Administration Agreement dated as of November 18, 1993. Under its 
Administration Agreement with the Fund, MAS receives an annual fee, accrued 
daily and payable monthly, of 0.08% of the Fund's average daily net assets, 
and is responsible for all fees payable under any sub-administration 
agreements. Chase Global Funds Services Company, a subsidiary of The Chase 
Manhattan Bank, N.A., 73 Tremont Street, Boston MA 02108-3913, serves as 
Transfer Agent to the Fund pursuant to an agreement also dated as of November 
18, 1993, and provides fund accounting and other services pursuant to a 
sub-administration agreement with MAS as Administrator. 

GENERAL DISTRIBUTION AGENT: Shares of the Fund are distributed exclusively 
through MAS Fund Distribution, Inc., a wholly-owned subsidiary of the 
Adviser. 

PORTFOLIO TRANSACTIONS: The investment advisory agreement authorizes the 
Adviser to select the brokers or dealers that will execute the purchases and 
sales of investment securities for each of the Fund's portfolios and directs 
the Adviser to use its best efforts to obtain the best execution with respect 
to all transactions for the portfolios. In doing so, a portfolio may pay 
higher commission rates than the lowest available when the Adviser believes 
it is reasonable to do so in light of the value of the research, statistical, 
and pricing services provided by the broker effecting the transaction. 

It is not the Fund's practice to allocate brokerage or principal business on 
the basis of sales of shares which may be made through intermediary brokers 
or dealers. However, the Adviser may place portfolio orders with qualified 
broker-dealers who recommend the Fund's Portfolios or who act as agents in 
the purchase of shares of the portfolios for their clients. 

Some securities considered for investment by each of the Fund's portfolios 
may also be appropriate for other clients served by the Adviser. If purchase 
or sale of securities consistent with the investment policies of a portfolio 
and one or more of these other clients served by the Adviser is considered at 
or about the same time, transactions in such securities will be allocated 
among the portfolio and clients in a manner deemed fair and reasonable by the 
Adviser. Although there is no specified formula for allocating such 
transactions, the various allocation methods used by the Adviser, and the 
results of such allocations, are subject to periodic review by the Fund's 
Trustees. MAS may use its broker dealer affiliates, including Morgan Stanley 
& Co., a wholly owned subsidiary of Morgan Stanley Group Inc., the parent of 
MAS's general partner and limited partner, to carry out the Fund's 
transactions, provided the Fund receives brokerage services and commission 
rates comparable to those of other broker dealers. 

OTHER INFORMATION: Description of Shares and Voting Rights: The Fund was 
established under Pennsylvania law by a Declaration of Trust dated February 
15, 1984, as amended and restated as of November 18, 1993. The Fund is 
authorized to issue an unlimited number of shares of beneficial interest, 
without par value, from an unlimited number of series (portfolios) of shares. 
Currently the Fund consists of twenty-six portfolios. 

The shares of each portfolio of the Fund are fully paid and non-assessable, 
and have no preference as to conversion, exchange, dividends, retirement or 
other features. The shares of each portfolio of the Fund have no preemptive 
rights. The shares of the Fund have non-cumulative voting rights, which means 
that the holders of more than 50% of the shares voting for the election of 
Trustees can elect 100% of the Trustees if they choose to do so. Shareholders 
are entitled to one vote for each full share held (and a fractional vote for 
each fractional share held), then standing in their name on the books of the 
Fund.
