MAS FUNDS (the Fund) is a no-load mutual fund consisting of twenty-eight
portfolios, twenty-five of which are described in this Prospectus. The Fund's
Small Cap Value Portfolio is not currently being offered to new investors. This
Prospectus offers the Institutional Class Shares of these twenty-five
portfolios.

SHARES OF THE CASH RESERVES PORTFOLIO 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.

</TABLE>

  The Total Operating Expense ratios reflected in the table above may be
  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 expenses that otherwise would be deducted from
  portfolio assets. Amounts in the above table have been restated to reflect
  current fees and expenses.
 *Until further notice, the Adviser has voluntarily agreed to waive its
  advisory fees and/or reimburse certain expenses to the extent necessary to
  keep Total Operating Expenses actually deducted from portfolio assets for the
  Emerging Markets Value, Cash Reserves, Mortgage-Backed Securities, Municipal,
  PA Municipal, Multi-Market Fixed Income and Multi-Asset-Class Portfolios from
  exceeding 1.18%, 0.32%, 0.50%, 0.50%, 0.50%, 0.58% and 0.78%, respectively.
  Absent such waivers and/or reimbursements by the Adviser, Total Operating
  Expenses would be 1.427%, 0.366%, 0.557%, 0.523%, 0.594%, 0.680% and 0.836%,
  for the Emerging Markets Value, Cash Reserves, Mortgage-Backed Securities,
  Municipal, PA Municipal, Multi-Market Fixed Income and Multi-Asset-Class
  Portfolios, respectively.
**Other expenses are based on estimated amounts for the current year.

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, which are
based on estimated expenses.

SUMMARY 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.

The Global Fixed Income, International Fixed Income and Emerging Markets Value
Portfolios are Non-Diversified for purposes of the Investment Company Act of
1940 (the "1940 Act"), meaning that they may invest a greater percentage of
assets in the securities of one issuer than the other portfolios. Each other
portfolio is diversified.

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. Certain FIXED
   INCOME SECURITIES may be highly sensitive to interest rate changes, and
   highly sensitive to the rate of principal payments (including prepayments on
   underlying mortgage assets). 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 Investment in smaller capitalization companies may involve greater risk than
   that customarily associated with investments in larger, more established
   companies. Smaller companies may have more limited markets and financial
   recources, narrow product lines or lack of depth of management. The
   securities of smaller companies are often traded in the over-the-counter
   market and, if listed on a national securities exchange, may not be traded in
   volumes typical for that exchange. Thus, the securities of smaller-sized
   companies may be less liquid, and subject to more abrupt or erratic market
   movements than securities of larger, more established growth companies;

 o 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 Investments in foreign securities involve certain special considerations
   which are not typically associated with investing in U.S. companies.
   Portfolios investing in foreign securities may also engage in foreign
   currency exchange transactions. See FORWARDS, FUTURES & OPTIONS, and SWAPS;


 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 a portion of
   its assets in DERIVATIVES including FUTURES & OPTIONS. Futures contracts,
   options and options on futures contracts entail certain costs and risks,
   including imperfect correlation between the value of the securities held by
   the portfolio and the value of the particular derivative instrument, and the
   risk that a portfolio could not close out a futures or options position when
   it would be most advantageous to do so;

 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; and

 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.

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 or the Fund's
Distributor, 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.

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).

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 a 30-day period 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 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 differs 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

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 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 restricted
securities eligible for resale to qualified institutional buyers pursuant to
Rule 144A under the Securities Act of 1933, commercial paper issued pursuant to
Section 4(2) under the Securities Act of 1933, or other restricted securities,
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 annual turnover. 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.

With respect to the fixed income portfolios and the fixed-income portion of the
Balanced, Multi-Asset-Class and Balanced Plus Portfolios, the annual turnover
rate will ordinarily exceed 100% due to changes in portfolio duration, yield
curve strategy or commitments with respect to forward delivery mortgage-backed
securities. For the Balanced, Multi-Asset-Class and Balanced Plus Portfolios,
annual turnover rate is not expected to exceed 100% with respect to EQUITY
SECURITIES.

The following portfolios have annual turnover rates of 100% or more: Mid Cap
Growth, Mid Cap Value, Small Cap Value, Domestic Fixed Income, Fixed Income,
Fixed Income II, Global Fixed Income, Intermediate Duration, International Fixed
Income, Limited Duration, Mortgage-Backed Securities, Special Purpose Fixed
Income, Balanced and Multi-Asset-Class. These high rates of annual 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 annual 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. The annual
turnover rate for each portfolio is shown in the Financial Highlights under
"Portfolio Turnover Rate."

<PAGE>

CASH EQUIVALENTS/TEMPORARY DEFENSIVE INVESTING: Although each portfolio intends
to remain substantially fully invested, a small percentage of a portfolio's
assets is 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, or
as detailed in Investment Limitations, 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, Emerging Markets Value and
International Fixed Income Portfolios. However, these portfolios will comply
with the diversification requirements imposed by Sub-Chapter M of the Internal
Revenue Code and;

(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, Emerging Markets Value and International Fixed Income Portfolios.
However, these portfolios will comply with the diversification requirements
imposed by Sub-Chapter M of the Internal Revenue Code.

Limitations (a) and (b) 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 the portfolios. 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 in this prospectus or the
Statement of Additional Information 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 portfolios' assets will not be considered a violation of the
restriction, and the sale of securities will not be required.

EMERGING MARKETS VALUE PORTFOLIO - (FORMERLY, THE EMERGING MARKETS PORTFOLIO)
(A NON-DIVERSIFIED PORTFOLIO)

Objective:             To achieve long-term capital growth by investing
                       primarily in common stocks of emerging markets issuers.

Approach:              The Adviser evaluates both short-term and long-term
                       international economic trends and relative attractiveness
                       of emerging markets and individual emerging market
                       securities. The Adviser selects common stocks which are
                       deemed to be undervalued at the time of purchase, based 
                       on proprietary measures of value.

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's investment process is designed to capture
                       value by identifying stocks that offer low but rising
                       expectations. To determine the level of expectations for
                       various companies and the direction of changes in those
                       expectations, the Adviser analyzes the companies' equity
                       valuations and changes in the companies' estimates of
                       future earnings. In addition, the Adviser diversifies
                       across sectors to preserve return while reducing risk,
                       seeking the best values within each sector of the market.
                       A group of senior investment professionals invests the
                       portfolio using a disciplined approach to stock selection
                       supported by fundamental research analysts. Each
                       investment professional makes his or her own buy, sell
                       and sector-allocation decisions. Overall sector
                       allocation is driven by bottom-up stock selection and is
                       reviewed regularly to preserve the benefits of
                       diversification.

Approach:              The Adviser selects common stocks meeting certain
                       criteria which the Adviser believes are related to the
                       stability and growth of the fundamental characteristics

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

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

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 selling 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 matching the S&P MidCap 400 Index (currently 
                       $500 million to $6 billion)

MID CAP 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
                       in the range of the companies 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.

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 equity capitalizations
                       in the range of the companies represented in the Russell
                       2000 Small Stock Index which 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 typica lly be lower
                       than for the Equity and Value Portfolios.

Approach:              The Adviser selects common stocks which are deemed to be

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, 
                       which are 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

DOMESTIC 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 and other investment grade
                       fixed-income securities of domestic issuers.

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 U.S. FIXED-INCOME
                       SECURITIES in all market sectors.

Policies:              Generally at least 65% invested in FIXED-INCOME 
                       SECURITIES
                       100% invested in domestic issuers
                       May invest greater than 50% in MORTGAGE SECURITIES
                       DERIVATIVES may be used to pursue portfolio strategy

                       May invest up to 20% in FIXED-INCOME SECURITIES rated BBB
                       (or its equivalent)

GLOBAL 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 in high grade fixed-income securities of
                       U.S. and foreign issuers. Total return is the combination
                       of income and changes in value. The portfolio's average
                       weighted maturity will ordinarily be greater than five
                       years.

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. The Adviser 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 65% invested in FIXED-INCOME
                       SECURITIES of issuers in at least 3 countries, one of
                       which may be the U.S.
                       DERIVATIVES may be used to represent country investments,
                       and otherwise pursue portfolio strategy

Quality 
Specifications:        95% INVESTMENT GRADE SECURITIES

Maturity and Duration: Average weighted maturity generally greater than 5 years

HIGH YIELD PORTFOLIO

Objective:             To achieve above-average total return over a market cycle
                       of three to five years, consistent with reasonable risk,
                       by investing in high yielding corporate fixed-income
                       securities (including bonds rated below investment grade,
                       commonly referred to as junk bonds). The portfolio may
                       also invest in U.S. Government securities,
                       mortgage-backed securities, investment grade corporate
                       bonds and in short-term fixed-income securities, such as
                       certificates of deposit, treasury bills, and commercial
                       paper. The portfolio expects to achieve its objective by
                       earning a high rate of current income, although the
                       portfolio may seek capital growth opportunities when
                       consistent with its objective. The portfolio's average
                       weighted maturity will ordinarily be greater than five
                       years.

Approach:              The Adviser uses equity and fixed-income valuation
                       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.

Policies:              Generally at least 65% invested in HIGH YIELD securities 
                       (commonly referred to as junk bonds)
                       DERIVATIVES may be used to pursue portfolio strategy

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.

Approach:              The Adviser constructs a portfolio with a duration

                       maturity and duration structure of the portfolio in
                       anticipation of long-term trends in interest rates and

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. The Adviser 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 strategy

Quality 
Specifications:        95% INVESTMENT GRADE SECURITIES

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. The Adviser
                       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.
                       The Adviser then strives to purchase the most
                       attractively priced portfolio that meets our duration and
                       investment objectives. When purchasing securities other
                       than U.S. GOVERNMENTS, the Adviser evaluates credit,
                       liquidity, and option risk. When the Adviser 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
                       SECURITIES
                       DERIVATIVES may be used to pursue portfolio strategy

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 SECURITIES.

Policies:              Generally at least 65% invested in MORTGAGE SECURITIES

MULTI-MARKET FIXED INCOME PORTFOLIO

Objective:             To realize above-average total return over a market cycle
                       of three to five years, consistent with reasonable risk,
                       by investing primarily in a diversified portofolio of
                       fixed-income securities of U.S. and foreign issuers.

Approach:              The Adviser determines the mix of investments in domestic
                       and foreign FIXED-INCOME AND HIGH YIELD SECURITIES
                       expected to maximize available total return. Strategic
                       judgements on the asset mix are based on valuation
                       disciplines and tools for analysis which have been
                       developed by the Adviser to compare the relative
                       potential returns and risks of global bond markets.

Policies:              Generally at least 65% in FIXED-INCOME SECURITIES

MUNICIPAL PORTFOLIO

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 structureNthe average
                       duration and maturity and the amount of the portfolio
                       invested in various types of bondsNaccording to its
                       outlook for interest rates and its analysis of the risks
                       and rewards offered by different classes of bonds. The
                       portfolio will invest in taxable bonds only in cases
                       where the Adviser believes they improve the risk/reward
                       profile of the portfolio on an after-tax basis.

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 and Pennsylvania personal
                       income tax by investing primarily in a diversified

                       outlook for interest rates and its analysis of the risks
                       and rewards offered by different classes of bonds. The
                       portfolio will invest in federally or Pennsylvania State
                       taxable bonds only in cases where MAS believes they
                       improve the risk/reward profile of the portfolio on an
                       after-tax basis for Pennsylvania residents.

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 SECURITIES

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 determines 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

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
                       of domestic and foreign issuers and fixed-income
                       securities.

Approach:              The Adviser determines the mix of investments in domestic
                       and foreign equity and fixed-income securities expected
                       to maximize available total return. Strategic judgments
                       on the asset mix are based on valuation disciplines and
                       tools for analysis which have been developed by the
                       Adviser to compare the relative potential returns and
                       risks of global stock and bond markets. When the Adviser
                       believes it to be in the best interests of the fund,
                       opportunistic investments in both the high yield and

                              PROSPECTUS GLOSSARY

            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 the
Adviser'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 Special Purpose Fixed
Income, Balanced, Multi-Asset-Class and Balanced Plus 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

- --------------------------------------------------------------------------------
MAS Fund - 38          Terms in BOLD TYPE are defined in the Prospectus Glossary

<PAGE>
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. FOREI GN 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. 

- --------------------------------------------------------------------------------
Terms in BOLD TYPE are defined in the Prospectus Glossary          MAS Fund - 39
<PAGE>

This lower liquidity might have an effect on a portfolio's ability to value or
dispose of such securities. Also, there 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.

Certain types of high yield bonds are non-income paying securities. For example,
ZERO COUPONS 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 as of September 30, 1997 (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.

</TABLE>


* The Adviser believes that these non-rated securities are equivalent in quality
to the rating indicated.

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.

The Adviser 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

- --------------------------------------------------------------------------------
MAS Fund - 40          Terms in BOLD TYPE are defined in the Prospectus Glossary
<PAGE>

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.

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 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), Fannie Mae, other government agencies, and private
issuers. It is expected that a portfolio's primary emphasis will be in MORTGAGE
SECURITIES issued by the various government-related organizations. However, a
portfolio may invest, without limit, in MORTGAGE 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 qualtity.

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-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.

- --------------------------------------------------------------------------------
Terms in BOLD TYPE are defined in the Prospectus Glossary          MAS Fund - 41
<PAGE>

MUNICIPALS MANAGEMENT: The Adviser 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.

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 1940 Act. 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 the Adviser 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 the Adviser's fixed-income investment strategy.

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.
ADRs also include American Depository Shares.

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 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

- --------------------------------------------------------------------------------
MAS Fund - 42          Terms in BOLD TYPE are defined in the Prospectus Glossary
<PAGE>

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 fairly 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 activel y 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).

Each portfolio may invest in obligations of U.S. banks, and, except for the
Domestic Fixed Income Portfolio, in 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.

The 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 the Cash Reserves Portfolio) may invest in COMMERCIAL
PAPER rated at time of purchase by one or more Nationally Recognized Statistical
Rating Organizations ("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;

- --------------------------------------------------------------------------------
Terms in BOLD TYPE are defined in the Prospectus Glossary          MAS Fund - 43
<PAGE>

(5) Government Agency 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, Fannie Mae,
Federal Financing Bank, the Tennessee Valley Authority, and others;

(6) REPURCHASE AGREEMENTS collateralized by securities listed above; and

(7) Investments by the Cash Reserves 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 SECURITIES will generally decline in price when
interest rates rise. 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.

COMMERCIAL PAPER: is a term used to describe short-term obligations with
maturities ranging from 2 to 270 days. These obligations are primarily issued by
corporations needing to finance large amounts of receivables, but may be issued
by banks and other borrowers. COMMERCIAL PAPER is issued either directly or
through broker-dealers, and may be discounted or interest-bearing. COMMERCIAL
PAPER is unsecured, but is almost always backed by bank lines of credit.
Virtually all COMMERCIAL PAPER is ranked by Moody's or Standard & Poor's.

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.

DEPOSITARY RECEIPTS: include both Global Depositary Receipts ("GDRs") and
European Depositary Receipts ("EDRs"), in addition to other similar types of
depositary shares, and are securities that can be traded in U.S. or foreign
securities markets but which represent ownership interests in a security or pool
of securities by a foreign or U.S.

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

<PAGE>

corporation. DEPOSITARY RECEIPTS may be sponsored or unsponsored. The depositary
of unsponsored DEPOSITARY RECEIPTS may provide less information to receipt
holders.

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. The portfolios may enter into
over-the-counter Derivatives transactions with counterparties approved by the
Adviser 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 a 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 during the 1940's, 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. As a result, 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's listing of Allowable Investments to determine which
of these 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.

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's listing of Allowable Investments
to determine which of these 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.

- --------------------------------------------------------------------------------
Terms in BOLD TYPE are defined in the Prospectus Glossary          MAS Fund - 45
<PAGE>

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
mortgages 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. Foreign Equities also include DEPOSITARY RECEIPTS. 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 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.

- --------------------------------------------------------------------------------
MAS Fund - 46          Terms in BOLD TYPE are defined in the Prospectus Glossary
<PAGE>

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 Securities and
Exchange Commission's ("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 CORPORATES,
PREFERRED STOCKS, and CONVERTIBLES 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.

         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." The rating C is reserved for income
         bonds on which "no interest is being paid." 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

- --------------------------------------------------------------------------------
Terms in BOLD TYPE are defined in the Prospectus Glossary          MAS Fund - 47
<PAGE>


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 1940 Act 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 or limit 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 (a) 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)); (b)
guaranteed by the U.S. Government or a private organization; or (c) considered
by the Adviser to be investment grade quality. 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 SECURITIES, including
mortgage pass-throughs and 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 fall 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 AND ASSIGNMENTS--A portfolio may invest in fixed rate and
floating rate loans ("Loans") arranged through private negotiations between an
issuer of sovereign debt obligations and one or more financial institutions
("Lenders"). A portfolio's investments in Loans are expected in most instances
to be in the form of participation in Loans ("Participations") and assignments
of all or a portion of Loans ("Assignments") from third parties. A portfolio
will have the right to receive payments of principal, interest and any fees to
which it is entitled only from the Lender selling the Participation and only
upon receipt by the Lender of the payments from the borrower. In the event of
the insolvency of the Lender selling a Participation, a portfolio may be treated
as a general creditor of the Lender and may not benefit from any set-off between
the Lender and the borrower. Certain Participations may be structured in a
manner designed to avoid purchasers of Participations being subject to the
credit risk of the Lender with respect to the Participation. Even under such a
structure, in the event of the Lender's insolvency, the Lender's servicing of
the Participation may be declared and the assignability of the Participation may
be impaired. A portfolio will acquire Participations only if the Lender
interpositioned between the portfolio and the borrower is determined by the
Adviser to be creditworthy.


- --------------------------------------------------------------------------------
MAS Fund - 48          Terms in BOLD TYPE are defined in the Prospectus Glossary
<PAGE>

When a portfolio purchases Assignments from Lenders it will acquire direct
rights against the borrower on the Loan. However, because Assignments are
arranged through private negotiations between potential assignees and potential
assignors, the rights and obligations acquired by the portfolio as the purchaser
of an Assignment may differ from, and be more limited than, those held by the
assigning Lender. Because there is no liquid market for such securities, the
portfolio anticipates that such securities could be sold only to a limited
number of institutional investors. The lack of a liquid secondary market may
have an adverse impact on the value of such securities and the portfolio's
ability to dispose of particular Assignments or Participations when necessary to
meet the portfolio's borrower. The lack of a liquid secondary market for
Assignments and Participations also may make it more difficult for the portfolio
to assign a value to those securities for purposes of valuing the portfolio's
holdings and calculating its net asset value.

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), Fannie Mae, private issuers and other government agencies.
There can be no assurance that the private insurers can meet their obligations
under the policies. Mortgage 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 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 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 U.S. Treasuries), 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. 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. Municipals 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.

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 SEC, 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

- --------------------------------------------------------------------------------
MAS Fund - 50          Terms in BOLD TYPE are defined in the Prospectus Glossary
<PAGE>


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 interest-only or 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 1940 Act. 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 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
the Adviser 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 notiona l 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

- --------------------------------------------------------------------------------
Terms in BOLD TYPE are defined in the Prospectus Glossary          MAS Fund - 51
<PAGE>

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 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 may 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 may be 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.

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 segregated account consisting of cash or liquid
securities in an amount at least equal to these commitments.

YANKEES: are U.S. dollar-denominated FIXED-INCOME SECURITIES issued by a
foreign government or corporation and sold in the U.S.

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 Coupons 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 or the Fund's Distributor, 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 General Shareholder Information-Valuation of Shares each day
that the portfolios are open for business. See Other Information-Closed Holidays
and General Shareholder Information--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 completing and signing an Account Registration Form (provided at the
end of the prospectus) and mailing it to MAS Funds c/o Miller Anderson &
Sherrerd, LLP, One Tower Bridge, West Conshohocken, Pennsylvania 19428-0868
together with a check ($5,000,000 minimum) payable to MAS Funds.

The portfolios requested should be designated on the Account Registration Form.
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 ordinarily credited at the net asset
value per share determined two business days after receipt of the check by the
Fund. Please note that payments to investors who redeem shares purchased by
check will not be made 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 (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

                        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.

- --------------------------------------------------------------------------------
Terms in BOLD TYPE are defined in the Prospectus Glossary          MAS Fund - 53
<PAGE>

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 additional investment $1,000)
by mailing a check (payable to MAS Funds) to MAS Funds' Client Services Group at
the address noted under Initial Purchase 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, 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. 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 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 additional investment amounts.

Purchases of a portfolio's 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

Shares of each portfolio may be redeemed by mail, or, if authorized, by
telephone. No charge is made for redemptions. The value of 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 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 Miller Anderson & Sherrerd, LLP, One Tower Bridge,
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.

- --------------------------------------------------------------------------------
MAS Fund - 54          Terms in BOLD TYPE are defined in the Prospectus Glossary
<PAGE>

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 Miller Anderson & Sherrerd, LLP, One Tower Bridge, 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 New York
Stock Exchange ("NYSE"), the Custodian, or the Fund is closed (see Other
Information-Closed Holidays) or under any emergency circumstances as determined
by the SEC.

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 SEC. 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 offering Institutional Class Shares
based on the respective net asset values of the shares involved. The exchange
privilege is only available, however, with respect to portfolios that are
qualified for sale in a shareholder's state of residence. There are no exchange
fees. Exchange requests should be sent to MAS Funds, c/o Miller Anderson &
Sherrerd, LLP, One Tower Bridge, West Conshohocken, PA 19428-0868.

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.
The sale of shares may result in a capital gain or loss 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 Miller Anderson & Sherrerd, LLP, One Tower Bridge,
West Conshohocken, PA 19428-0868. As in the case of redemptions, the written
request must be received in good order as defined above. Unless shares are being
transferred to an existing account, requests for transfer must be accompanied by
a completed Account Registration Form for the receiving party.

VALUATION OF SHARES

EMERGING MARKETS VALUE, EQUITY, GROWTH, INTERNATIONAL EQUITY, MID CAP GROWTH,
MID CAP VALUE, SMALL CAP VALUE AND VALUE PORTFOLIOS:

 Net asset value per share 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 values of other assets and securities for which no quotations are
readily available (including restricted securities), and, to the extent
permitted by the SEC, securities for which the value has been materially
affected by events occurring after the close of the market on which they
principally trade, are determined in good faith at fair value using methods
approved by the Trustees.

DOMESTIC FIXED INCOME, FIXED INCOME, FIXED INCOME PORTFOLIO II, GLOBAL FIXED
INCOME, HIGH YIELD, INTERMEDIATE DURATION, INTERNATIONAL FIXED INCOME, LIMITED
DURATION, MORTGAGE-BACKED SECURITIES, MULTI-MARKET FIXED INCOME, MUNICIPAL, PA
MUNICIPAL AND SPECIAL PURPOSE FIXED INCOME 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 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 w
hich 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-INC OME
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), and, to the extent permitted by the SEC,
securities for which the value has been materially affected by events occurring
after the close of the market on which they principally trade, will be valued in
good faith at fair value using methods approved by the Board of Trustees.

BALANCED, BALANCED PLUS 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,
Multi-Asset-Class and Balanced Plus 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.

MAS Fund - 56          Terms in BOLD TYPE are defined in the Prospectus Glossary

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 1940 Act. 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 Board of Trustees has 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
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 Board of 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 Board of 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.

ALL PORTFOLIOS: Net asset value per share for Investment Class Shares,
Institutional Class Shares and Adviser Class Shares may differ due to
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.

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

* The Equity, Value, Growth, Fixed Income, Fixed Income II, Special Purpose
Fixed Income, High Yield, Limited Duration, Intermediate Duration,
Mortgage-Backed Securities, Balanced, Multi-Asset-Class, Global Fixed Income,
International Fixed Income, Multi-Market Fixed Income, Domestic Fixed Income and
Balanced Plus Portfolios normally distribute substantially all of their net
investment income to shareholders on a quarterly basis.

* The International Equity, Emerging Markets Value, Small Cap Value, Mid Cap
Value and Mid Cap Growth Portfolios normally distribute substantially all of
their net investment income on an annual basis.

* The Municipal and the PA Municipal Portfolios normally distribute
substantially all of their net investment income on a monthly basis.

- --------------------------------------------------------------------------------
Terms in BOLD TYPE are defined in the Prospectus Glossary          MAS Fund - 57
<PAGE>

* The Cash Reserves Portfolio declares distributions daily and normally
distributes substantially all of its investment income on a monthly basis.

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 gains are realized from the sale of underlying securities, the portfolios
normally distribute such gains with the last distribution 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.

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. 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.

TAXES: The following is a summary of some important tax issues that affect the
portfolios of the Fund and their shareholders. The summary is based on current
tax laws and regulations, which may be changed by legislative, judicial or
administrative action. No attempt has been made to present a detailed
explanation of the tax treatment of each portfolio or its shareholders. More
information about taxes is in the Statement of Additional Information.
Shareholders are urged to consult their tax advisors regarding sp ecific
questions as to federal, state and local income taxes.

FEDERAL TAXES: Each portfolio of the Fund is treated as a separate entity for
federal income tax purposes and intends to qualify for the special tax treatment
afforded regulated investment companies. As such, each portfolio will not be
subject to federal income tax to the extent it distributes net investment
company taxable income and net capital gains to shareholders. The Fund will
notify shareholders annually as to the tax classification of all distributions.

 Income dividends received by shareholders (except for shareholders of the
Municipal and PA Municipal Portfolios (see Special Tax Considerations for the
Municipal and PA Municipal Portfolios) will be taxable as ordinary income,
whether received in cash or in additional shares. In the case of the Equity,
Value, Small Cap Value, Mid Cap Growth, Growth, Balanced, Balanced Plus,
Multi-Asset-Class and Mid Cap Value Portfolios, corporate shareholders may be
entitled to a dividends-received deduction for the portion of dividends they
receive which are attributable to dividends received by such portfolios from
U.S. corporations. Capital gains distributions are taxable to shareholders at
capital gains rates. Each portfolio will designate capital gains distributions
 to individual shareholders as either subject to the federal capital gains rate
imposed on property held for more than 18 months or on property held for more
than 1 year but not more than 18 months.

Distributions paid in January but declared by a portfolio in October, November
or December of the previous year are taxable to shareholders in the previous
year.

<PAGE>


Each portfolio intends to declare and pay dividends and distributions so as to
avoid imposition of the federal excise tax applicable to regulated investment
companies. Further discussion is included in the Statement of Additional
Information.

The Fund is required by federal law to withhold 31% of reportable payments
(which may include dividends and capital gains distributions) paid to
shareholders. In order to avoid this withholding requirement, shareholders must
certify on their Account Registration Forms that their Social Security Number or
Taxpayer Identification Number is correct, and that they are not subject to
backup withholding. Exchanges and redemptions of shares in a portfolio are
taxable events.

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. Each of the International Equity, Emerging Markets Value, Global Fixed
Income, International Fixed Income, Multi-Market Fixed Income, Multi-Asset-Class
and Balanced Plus Portfolios may be able to file an election with the Internal
Revenue Service to pass through to its shareholders for foreign tax credit
purposes the amount of foreign income taxes paid by such portfolio. Further
discussion is included in the Statement of Additional Information. The other
portfolios of the Fund will not be able to make this election.

STATE AND LOCAL INCOME TAXES: The Fund is formed as a Pennsylvania Business
Trust and is not liable for any corporate income or franchise tax in the
Commonwealth of Pennsylvania. Shareholders should consult their tax advisors for
the state and local income tax consequences of distributions from the
portfolios.

SPECIAL TAX CONSIDERATIONS FOR THE MUNICIPAL AND PA MUNICIPAL PORTFOLIOS: Each
of the Municipal and PA Municipal Portfolios intends to pay "exempt-interest"
dividends to shareholders which are excluded from a shareholder's gross income
for federal income tax purposes. Exempt-interest dividends received by
shareholders from such portfolios may be subject to state and local taxes,
although some states allow a shareholder to exclude that portion of a
portfolio's tax-exempt income which is accountable to municipal securities
issued within the shareholder's state of residence.

Since each of the portfolios may invest in private activity municipal
securities, investment in either of the portfolios may not be an appropriate
investment for persons who are "substantial users" (or persons related to
"substantial users") of facilities financed by industrial development bonds or
private activity bonds.

To the extent, if any, that distributions paid to shareholders of either
portfolio are derived from taxable interest or capital gains, such distributions
will be subject to federal income tax. Additionally, such distributions are not
eligible for the dividends received deduction for corporations.

Furthermore, the PA Municipal Portfolio invests at least 65% of its assets in PA
Municipals. As a result, the income of the PA Municipal 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.

Further discussion of tax considerations affecting shareholders of these
portfolios is found in the Statement of Additional Information.

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, wholly owned by indirect subsidiaries of Morgan Stanley Dean
Witter & Co., and is located at One Tower Bridge, West Conshohocken, PA 19428.

<PAGE>

The Adviser provides investment services to employee benefit plans, endowment
funds, foundations and other institutional investors and as of December 31, 1997
had in excess of $59.4 billion in assets under management. On May 31, 1997,
Morgan Stanley Group Inc., then the indirect parent of the Adviser, merged with
Dean Witter, Discover & Co. to form Morgan Stanley Dean Witter & Co. (formerly,
Morgan Stanley, Dean Witter, Discover & Co.). In connection with this
transaction, the Adviser entered into a new Investment Management Agreement
("Agreement") with MAS Funds dated May 31, 1997, which Agreement was approved by
the shareholders of each portfolio at a special meeting held on May 1, 1997 or
at an adjournment of such meeting held on May 12, 1997. 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. The following table shows the Adviser's contractual rate
(annualized) along with the Adviser's actual rate of compensation for the Fund's
1997 fiscal year.

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, 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 or markups on principal transactions 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 or dealer
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. The Adviser may
place a combined order for two or more accounts or portfolios for the purchase
or sale of the same security if, in its judgement, joint execution is in the
best interest of each participant and will result in best price and execution.
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. The Adviser may use its broker dealer affiliates, including Morgan
Stanley & Co., a wholly owned subsidiary of Morgan Stanley, Dean Witter,
Discover & Co., 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-eight 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.

Meetings of shareholders will not be held except as required by the 1940 Act and
other applicable law. A meeting will be held to vote on the removal of a Trustee
or Trustees of the Fund if requested in writing by the holders of not less than
10% of the outstanding shares of the Fund. The Fund will assist in shareholder
communication in such matters to the extent required by law.

As of January 5, 1998, Northern Trust Company (Chicago, IL) owned a controlling
interest (as that term is defined by the 1940 Act) of the Cash Reserves
Portfolio; The Northwestern University Investment Department (Evanston, IL) and
Cives Corporation Savings and Profit-Sharing Retirement Trust (Roswell, GA)
owned a controlling interest of the Mortgage-Backed Securities Portfolio;
Ministers and Missionaries Benefit Board of the American Baptist Convention (New
York, NY) and Chemical Bank (New York, NY) owned a controlling interest of the
Emerging Markets Value Portfolio; Northern Trust Company (Chicago, IL) owned a
controlling interest of the Balanced Portfolio; The Charles A. Dana Foundation
Inc. (New York, NY) owned a controlling interest of the Global Fixed Income
Portfolio; Southwest National Bank of Pennsylvania (Greensburg, PA) owned a
controlling interest of the Intermediate Duration Portfolio; and the Connelly
Foundation (West Conshohocken, PA) owned a controlling interest of the
Multi-Market Fixed Income Portfolio.

CUSTODIANS: The Chase Manhattan Bank, New York, NY and Morgan Stanley Trust
Company (NY), Brooklyn, NY serve as custodians for the Fund. The custodians hold
cash, securities and other assets as required by the 1940 Act.

TRANSFER AND DIVIDEND DISBURSING AGENT: Chase Global Funds Services Company, a
subsidiary of The Chase Manhattan Bank, 73 Tremont Street, Boston, MA
02108-3913, serves as the Funds' Transfer Agent and dividend disbursing agent.

REPORTS: Shareholders receive semi-annual and annual financial statements.
Annual financial statements are audited by Price Waterhouse LLP, independent
accountants.

LITIGATION: The Fund is not involved in any litigation.

CLOSED HOLIDAYS: Currently, the weekdays on which the Fund is closed for
business are: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day,
Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day. In addition, the Cash Reserves Portfolio will be closed on
Columbus Day and Veteran's Day.

YEAR 2000: The management and distribution services provided to the Fund by the
Adviser and the Distributor depend on the smooth funcioning of their computer
systems. Many computer software systems in use today cannot recognize the year
2000, but revert to 1900 or 1980, due to the manner in which dates were encoded
and calculated. That failure could have a negative impact on the handling of
securities trades, pricing and account services. The Adviser and the Distributor
have been actively working on necessary change s to their own computer systems
to deal with the year 2000 problem and expect that their systems will be adapted
before that date. There can be no assurance, however, that they will be
successful. In addition, other unaffiliated service providers may be faced with
similar problems. The Adviser and the Distributor are monitoring their remedial
efforts, however, there can be no assurance that they and the services they
provide will not be adversely affected.

In addition, it is possible that the markets for securities in which the
portfolios invest may be detrimentally affected by computer failures throughout
the financial services industry beginning January 1, 2000. Improperly
functioning trading systems may result in settlement problems and liquidity
issues. In addition, corporate and governmental data processing errors may
result in production problems for individiual companies and overall economic
uncertainties. Earnings of individual issuers will be affecte d by remediation
costs, which may be substantial and may be reported inconsistently in U.S. and
foreign financial statements. Accordingly, the portfolios investments may be
adversely affected.

    Part 2. BACKUP WITHHOLDING 
    / / Check the box if the account is subject to Backup Withholding under 
    the provisions of Section 3406(a)(1)(C) of the Internal Revenue Code.
- -------------------------------------------------------------------------------
                           IMPORTANT TAX INFORMATION
You (as a payee) are required by law to provide us (as payer) with your correct
taxpayer identification number. Accounts that have a missing or incorrect 
taxpayer identification number will be subject to backup withholding at a 31%
rate on ordinary income and capital gains distribution as well as redemptions.
Backup withholding is not an additional tax; the tax liability of person subject
to backup withholding will be reduced by the amount of tax withheld.

You may be notified that you are subject to backup withholding under section
3406(a)(1)(C) because you have underreported interest or dividends or you were
required to, but failed to, file a return which would have included a reportable
interest or dividend payment. If you have been so notified, check the box in
PART 2 at left.
