MAS Funds (the Fund) is a no-load mutual fund consisting of twenty-six
portfolios, twenty-three of which are described in this Prospectus. Each
portfolio in this Prospectus operates as a separate diversified investment
company except the Global Fixed Income and International Fixed Income Portfolios
which are non-diversified investment companies. The investment objective of each
portfolio is described with a summary of investment policies as referenced
below. The Fund's Small Cap Value Portfolio is not currently being offered to
new investors. This Prospectus offers the Institutional Class Shares of the
Fund. The Fund also offers Adviser Class Shares and Investment Class Shares.
- -------------------------------------------------------------------------------

- -------------------------------------------------------------------------------
Shares of the Cash Reserves Portfolios are neither insured nor guaranteed by the
U.S. Government. The Portfolio seeks to maintain, but there can be no assurance
that it will be able to maintain, a constant net asset value of $1.00 per share.
- -------------------------------------------------------------------------------

The High Yield Portfolio will invest primarily, and certain other portfolios of
the Fund may invest to varying degrees, in high yield, high risk securities
which are speculative with regard to payment of interest and return of principal
(commonly referred to as junk bonds); therefore, investments in these portfolios
may not be suitable for all investors. See High Yield Investing in the Glossary
of Strategies for additional information regarding certain risks associated with
investment in such securities.

  Where applicable as described in Financial Highlights, the Total Operating 
  Expense ratios reflected in the table above are higher than the ratio of 
  expenses actually deducted from portfolio assets because of the effect of 
  expense offset arrangements. The result of such arrangements is to offset 
  expense that otherwise would be deducted from portolio assets.
 
* Until further notice, the Adviser has voluntarily agreed to waive its advisory
  fees and reimburse certain expenses to the extent necessary to keep Total
  Operating Expenses actually deducted from portfolio assets for the Mid Cap
  Value, Cash Reserves, Domestic Fixed Income, Intermediate Duration, Limited
  Duration, Mortgage-Backed Securities, Municipal, PA Municipal and
  Multi-Asset-Class Portfolios from exceeding 0.88%, 0.32%, 0.50%, 0.52%, 0.42%,
  0.50%, 0.50%, 0.50% and 0.780%, respectively. Absent fee waivers and
  reimbursements by the Adviser, Total Operating Expenses would be 1.068%,
  .422%, .530%, .689%, .540%, .596%, .653% and .860%, for the Mid Cap Value,
  Cash Reserves, Domestic Fixed Income, Intermediate Duration, Mortgage-Backed
  Securities, Municipal, PA Municipal and Multi-Asset-Class Portfolios,
  respectively.
 
+ On November 21, 1996 shareholders of the Multi-Asset-Class Portfolio approved
  an increase in the Advisory Fee from 0.45% to 0.65% of average daily net
  assets. The Investment Advisory Fees and Total Operating Expenses have been
  adjusted to reflect this change.

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.

ordinarily representing between 45% and 75% of the total investment. The 
average weighted maturity of the fixed-income portion of the portfolio will 
ordinarily be greater than five years. 

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

Balanced Plus Portfolio - seeks to achieve above average total return over a 
market cycle of three to five years, consistent with reasonable risk, by 
investing in a diversified portfolio of Common Stocks of domestic and foreign 
issuers and Fixed-Income Securities. 

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

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

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

o  Each portfolio (except the Cash Reserves Portfolio) may invest 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 

- --------------------------------------------------------------------------------
MAS Funds - 6         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

   require the portfolio to segregate some or all of its cash or liquid 
   securities to cover its obligations pursuant to such instruments. As asset 
   segregation reaches certain levels, a portfolio may lose flexibility in 
   managing its investments properly, responding to shareholder redemption 
   requests, or meeting other obligations and may be forced to sell other 
   securities that it wanted to retain or to realize unintended gains or 
   losses; 

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

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

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

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

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

HOW TO INVEST: Institutional Class Shares of each portfolio are available to 
clients of the Adviser with combined investments of $5,000,000 and 
Shareholder Organizations who have a contractual arrangement with the Fund 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.

##   For the periods ended September 30, 1995 and 1996, the Ratio of Expenses to
     Average Net Assets for the Mid Cap Growth and Mid Cap Value Portfolios
     excludes the effect of expense offsets. If expense offsets were included,
     the Ratio of Expenses to Average Net Assets would be 0.60% and 0.60%,
     respectively, for the Mid Cap Growth Portfolio and 0.88%* and 0.88%,
     respectively, for the Mid Cap Value Portfolio. For the periods ended
     September 30, 1995 and 1996, the Ratio of Expenses to Average Net Assets
     for the Small Cap Value Portfolio excludes the effect of expense offsets.
     If expense offsets were included, the Ratio of Expenses to Average Net
     Assets would not significantly differ. For the periods ended September 30,
     1995 and 1996, the Ratio of Expenses to Average Net Assets for the Value
     Portfolio excludes the effect of expense offsets. If expense offsets were
     included, the Ratio of Expenses to Average Net Assets would be 0.60% and
     0.60% respectively. o Net Investment Income, the Ratio of Net Investment
     Income to Average Net Assets and the Portfolio Turnover Rate reflect
     activity relating to a nonrecurring initiative to invest in higher-paying
     dividend income producing securities. ### For fiscal years beginning on or
     after September 1, 1995, a fund is required to disclose the average
     commission rate paid for trades on which commissions were charged.

YIELD AND TOTAL RETURN: 

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

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

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

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

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

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

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

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

GENERAL INFORMATION: 

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

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

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

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

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

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

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 to forward delivery 
mortgage-backed securities. 

The Balanced Plus Portfolio's annual turnover rate is not expected to exceed 
100% with respect to Equity Secur- ities. The annual turnover rate with 
respect to the fixed income portion of the portfolio will ordinarily exceed 
100% due to changes in portfolio duration, yield curve strategy or 
commitments to forward delivery mortgage-backed securities.

Fixed Income - 124%, Limited Duration - 174%, Mortgage-Backed Securities - 
116%, Special Purpose Fixed Income - 151%, Balanced - 110% and 
Multi-Asset-Class - 122%. 

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

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

Concentration: Concentration is defined as investment of 25% or more of a 
portfolio's total assets in the securities of issuers operating in any one 
industry. Except as provided in a portfolio's specific investment policies, 
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 and International Fixed Income Portfolios. However, these portfolios 
will comply with the diversification requirements imposed by Sub- Chapter M 
of the Internal Revenue Code; 

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

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

(d) a portfolio will not make loans except (i) by purchasing debt securities 
in accordance with its investment objectives and policies, or entering into 
Repurchase Agreements, (ii) by lending its portfolio securities and (iii) by 
lending portfolio assets to other portfolios of the Fund, so long as such 
loans are not inconsistent with the Invest-

ment Company Act of 1940, as amended or the Rules and Regulations, or 
interpretations or orders of the Securities and Exchange Commission 
thereunder; 

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

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

(g) a portfolio will not invest its assets in securities of any Investment 
Company, except as permitted by the 1940 Act or the rules, regulations, 
interpretations or orders of the SEC and its staff thereunder. 

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

Equity Portfolio 

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

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

Policies:                  Generally at least 65% invested in Equity 
                           Securities 
                           Up to 5% invested in Foreign Equities

Growth Portfolio 

Objective:                 To achieve long-term capital growth by 
                           investing primarily in common stocks of large 
                           size companies which the Adviser believes 
                           offer long-term growth potential. 

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

Objective:                 To achieve above-average total return over a

                           the United States. 

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

Mid Cap Growth Portfolio 

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

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

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

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. 

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

Capitalization Range:      Generally matching the S&P MidCap 400 Index 
                           (currently $500 million to $6 billion)

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 typically be lower than 
                           for the Equity and Value Portfolios. 

Approach:                  The Adviser selects common stocks which are 
                           deemed to be undervalued at the time of 
                           purchase, based on proprietary measures of 
                           value. The Portfolio will be structured taking 
                           into account the economic sector weights of 
                           the Russell 2000 Index, with the portfolio's 
                           sector weights normally being within 5% of the 
                           sector weights for the Index. 

Policies:                  Generally at least 65% invested in Equity 
                           Securities of small-cap companies deemed to be 
                           undervalued 
                           Up to 5% invested in Foreign Equities 
                           (excluding ADRs) 
                           Derivatives may be used to pursue portfolio 
                           strategy 

Capitalization Range:      Generally matching the Russell 2000 size 
                           distribution (currently $50 million to $1 
                           billion)

Value Portfolio 

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

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

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

Cash Reserves Portfolio 

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

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

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

                           than five years. 

Approach:                  The Adviser manages the duration, country, and 
                           currency exposure of the Portfolio by

                           investments are in government and

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.

                           securities, investment grade corporate bonds

                           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

                           years.

                           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 (including bonds rated below

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

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

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

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

Limited Duration Portfolio 

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

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

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

Mortgage-Backed Securities Portfolio 

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

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

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

Quality Specifications:    Securities not guaranteed by the U.S. 
                           Government or a private organization will be 
                           rated Investment Grade Securities 

Maturity and Duration:     Average weighted maturity generally greater 
                           than 7 years 
                           Duration generally between 2 and 7 years

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 structure--the 
                           average duration and maturity and the amount 
                           of the portfolio invested in various types of 
                           bonds--according 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 MAS 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 portfolio of 
                           fixed-income securities. 

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

                           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.

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 
                           Derivatives may be used to pursue portfolio

                           market cycle of three to five years, 
                           consistent with reasonable risk, by investing 
                           in a diversified portfolio of common stocks 
                           and fixed-income securities of United States

Approach:                  The Adviser determines the mix of investments

                           fixed-income and high yield securities

                           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

Balanced Plus 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 of 
                           domestic and foreign issuers and fixed-income 
                           securities.

                           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 international fixed-income

                             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 
MAS's outlook for the economy and different market sectors, the mix between 
value stocks and growth stocks will change. 

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

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

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

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

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

<PAGE>

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

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

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

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

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

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

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

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

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

- -------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 39
<PAGE>

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

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

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

   The table below provides a summary of ratings assigned to all U.S. and 
foreign debt holdings of those portfolios with more than 5% invested in High 
Yield securities as of September 30, 1996 (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. The Balanced Plus Portfolio had not 
commenced operations as of September 30, 1996.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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 addition the 
short-term nature of the loans reduces the impact of any change in prepayment 
level. Due to amortization, the average life for these securities is also the 
conventional proxy for maturity. 

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

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

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

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

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

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 princi-

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

pal amount of such investment is insured in full by the Federal Deposit 
Insurance Corporation, (ii) in the case of U.S. banks, it is a member of the 
Federal Deposit Insurance Corporation, and (iii) in the case of foreign 
branches of U.S. banks, the security is deemed by the Adviser to be of an 
investment quality comparable with other debt securities which may be 
purchased by the portfolio. 

(2) Each portfolio (except Cash Reserves) may invest in commercial paper 
rated at time of purchase by one or more 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; 

(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, Federal 
National Mortgage Association, Federal Financing Bank, the Tennessee Valley 
Authority, and others; 

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

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

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

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

Like bonds in general, mortgage-backed securities will generally decline in 
price when interest rates rise. 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.

MAS Funds - 44      Terms in bold type are defined in the Prospectus Glossary
<PAGE>

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. 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. All of 
the portfolios of MAS Funds, except the Cash Reserves Portfolio, may enter 
into over-the-counter Derivatives transactions (Swaps, Caps, Floors, Puts, 
etc., but excluding CMOs, Forwards, Futures and Options, and SMBS) with 
counterparties approved by MAS in accordance with guidelines established by 
the Board of Trustees. These guidelines provide for a minimum credit rating 
for each counterparty and various credit enhancement techniques (for example, 
collateralization of amounts due from counterparties) to limit exposure to 
counterparties with ratings below AA. Derivatives include, but are not 
limited to, CMOs, Forwards, Futures and Options, SMBS, Structured 
Investments, Structured Notes and Swaps. See each individual Portfolio's 
listing of Allowable Investments to determine which of these the Portfolio 
may hold. 

Eastern European Issuers: The economies of Eastern European countries are 
currently suffering both from the stagnation resulting from centralized 
economic planning and control and the higher prices and unemployment 
associated with the transition to market economics. Unstable economic and 
political conditions may adversely affect security values. Upon the accession 
to power of Communist regimes 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. In the event of the return to power of the Communist Party, there 
can be no assurance that the portfolio's investments in Eastern Europe would 
not be expropriated, nationalized or otherwise confiscated. 

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

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

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

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

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

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

Foreign Equities: are Common Stock, Preferred Stock, Rights and Warrants of 
foreign issuers denominated in foreign currency and traded primarily in 
non-U.S. markets. 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. 

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

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. 

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

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

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

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

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

    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." C The rating C is reserved for 
    income bonds on which "no interest is being paid." D - Debt rated D 
    is in "default", and "payment of interest and/or repayment of 
    principal is in arrears." 

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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 

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

required. The debt of these agencies is supported by assets of, or revenues 
derived from, the various projects financed; it is not an obligation of the 
Commonwealth. Some of these agencies, however, such as the Delaware River 
Joint Toll Bridge Commission, are indirectly dependent on Commonwealth funds 
through various state-assisted programs. 

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

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

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

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

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

SMBS are usually structured with two classes that receive different 
proportions of the interest and principal distributions on a pool of mortgage 
assets. One type of SMBS will have one class receiving some of the interest 
and most of the principal from the mortgage assets, while the other class 
will receive most of the interest and the remainder of the principal. In some 
cases, one class will receive all of the interest (the 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 Investment Company Act of 1940. A 
trust unit pays a return based on the total return of securities and other 
investments held by the trust and the trust may enter into one or more Swaps 
to achieve its objective. For example, a trust may purchase a basket of 
securities and 

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

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

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

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

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

Possible Risks: Interest rate and total rate of return swaps do not involve 
the delivery of securities, other underlying assets, or principal. 
Accordingly, the risk of loss with respect to interest rate and total rate of 
return swaps is limited to the net amount of interest payments that a 
portfolio is contractually obligated to make. If the other party to an 
interest rate or total rate of return swap defaults, a portfolio's risk of 
loss consists of the net amount of interest payments that a portfolio is 
contractually entitled to receive. In contrast, currency swaps 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. 

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

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

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

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

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

GENERAL SHAREHOLDER INFORMATION 

                              PURCHASE OF SHARES 

Institutional Class Shares are available to clients of the Adviser with 
combined investments of $5,000,000 and Shareholder Organizations who have a 
contractual arrangement with the Fund 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 Other Information-Valuation of Shares each day that 
the portfolios are open for business. See Other Information-Closed Holidays 
and Valuation of Shares. 

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

Initial Purchase by Mail: Subject to acceptance by the Fund, an account may 
be opened by 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 

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

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

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

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

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

Additional Investments: Additional investments of Institutional Class Shares 
at net asset value may be made at any time (minimum investment $1,000) by 
mailing a check (payable to MAS Funds) to MAS Funds' Client Services Group at 
the address noted under Initial 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 Institutional Class Shares of any of 
its portfolios or to reject any purchase orders when, in the judgment of 
management, such suspension or rejection is in the best interest of the Fund. 
The Fund also reserves the right, in its sole discretion, to waive the 
minimum initial and subsequent investment amounts. 

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

Institutional Class Shares of the Fund's portfolios are also sold to 
corporations or other institutions such as trusts, foundations or 
broker-dealers purchasing for the accounts of others (Shareholder 
Organizations). Investors purchasing and redeeming shares of the portfolios 
through a Shareholder Organization may be charged a transaction-based fee or 
other fee for the services of such organization. Each Shareholder 
Organization is responsible for transmitting to its customers a schedule of 
any such fees and information regarding any additional or different 
conditions 

- --------------------------------------------------------------------------------
MAS Funds - 54      Terms in bold type are defined in the Prospectus Glossary

regarding purchases and redemptions. Customers of Shareholder Organizations 
should read this Prospectus in light of the terms governing accounts with 
their organization. The Fund does not pay compensation to or receive 
compensation from Shareholder Organizations for the sale of Institutional 
Class Shares. 

                             REDEMPTION OF SHARES 

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

By Mail: Each portfolio will redeem Institutional Class Shares at the net 
asset value next determined after the request is received in good order. 
Requests should be addressed to MAS Funds, c/o 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. 

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 NYSE, the Custodian, or the Fund is closed (see Other 
Information-Closed Holidays) or under any emergency circumstances as 
determined by the Securities and Exchange Commission. 

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

                             SHAREHOLDER SERVICES 

Exchange Privilege: Each portfolio's Institutional Class Shares may be 
exchanged for shares of the Fund's other portfolios 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 registered for sale in a shareholder's state of residence. There are 
no exchange fees. Exchange requests should be sent to MAS Funds, c/o 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 

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 value of other assets and securities 
for which no quotations are readily available (including restricted 
securities) are determined in good faith at fair value using methods approved 
by the Trustees.

<PAGE>

Domestic Fixed Income, Fixed Income, Fixed Income Portfolio II, Global Fixed 
Income, High Yield, Intermediate Duration, International Fixed Income, 
Limited Duration, Mortgage-Backed Securities, 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 
which is accrued daily. Bonds and other Fixed-Income Securities which are 
traded over the counter and on an exchange will be valued according to the 
broadest and most representative market, and it is expected that for bonds 
and other Fixed-Income Securities this ordinarily will be the 
over-the-counter market. 

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

Balanced, Multi-Asset-Class and Balanced Plus 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. 

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

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

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

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

The Trustees have also agreed to establish procedures reasonably designed, 
taking into account current market conditions and the portfolio's investment 
objective, to stabilize the net asset value per share as computed for the 
purposes of sales and redemptions at $1.00. These procedures include periodic 
review, as the Trustees deem appropriate and at such intervals as are 
reasonable in light of current market conditions, of the relationship between 
the amortized cost value per share and a net asset value per share based upon 
available indications of market value. In such a review, investments for 
which market quotations are readily available are valued at the most recent 
bid price or quoted yield equivalent for such securities or for securities of 
comparable maturity, quality and type as obtained from one or more of the 
major market makers for the securities to be valued. Other investments and 
assets are valued at fair value, as determined in good faith by the Trustees. 

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

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

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

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

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

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

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

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

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

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

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

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. 

Federal Taxes: The following summary of Federal income tax consequences 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 federal income tax treatment of the 
portfolio or its shareholders. In addition, state and local tax consequences 
of an investment in the portfolio may differ from the Federal income tax 
consequences described below. Accordingly, shareholders are urged to consult 
their tax advisers regarding specific questions as to federal, state and 
local taxes. 

Each portfolio of the Fund intends to qualify for taxation as a regulated 
investment company under the Internal Revenue Code of 1986 (the "Code") so 
that each portfolio will not be subject to Federal income tax to the extent 
it distributes investment company taxable income and net capital gain (the 
excess of net long-term capital gain over net short-term capital loss) to 
shareholders. Each Portfolio is treated as a separate entity for Federal 
income tax purposes and is not combined with any of the Funds' other 
portfolios. Dividends, either in cash or reinvested in shares, paid by a 
portfolio, except for the Municipal and PA Municipal Portfolios (see Special 
Tax Considerations for the Municipal and PA Municipal Portfolios) from net 
investment income will be taxable to shareholders as ordinary income. 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, such dividends 
paid to corporate shareholders will generally qualify in part for the 
dividends received deduction for corporations to the extent attributable to 
dividends received by such portfolios from domestic corporations. The Fund 
will send each shareholder a statement each year indicating the amount of the 
dividend income which qualifies for such treatment. 

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

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

Each portfolio intends to declare and pay dividends and capital gain 
distributions so as to avoid imposition of the Federal excise tax. To do so, 
each portfolio expects to distribute an amount at least equal to (i) 98% of 
its calendar year ordinary income, (ii) 98% of its capital gains net income 
(the excess of short and long-term capital gain over short and long-term 
capital loss) for the one-year period ending October 31st, and (iii) 100% of 
any undistrib- 

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

uted ordinary and capital gain net income from the prior year. Dividends 
declared in October, November or December by a portfolio will be deemed to 
have been paid by such portfolio and received by shareholders on December 
31st of the declared year provided that the dividends are paid before 
February 1 of the following year. 

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

Foreign Income Taxes: Investment income received by the portfolios from 
sources within foreign countries may be subject to foreign income taxes 
withheld at the source. The U.S. has entered into Tax Treaties with many 
foreign countries which entitle these portfolios to a reduced rate of tax or 
exemption from tax on such income. It is impossible to determine the 
effective rate of foreign tax in advance since the amount of the portfolios' 
assets to be invested within various countries is not known. The portfolios 
intend to operate so as to qualify for treaty reduced rates of tax where 
applicable. 

The International Equity, Global Fixed Income and International Fixed Income 
Multi-Asset-Class and Balanced Plus Portfolios may file an election with the 
Internal Revenue Service to pass through to the portfolio's shareholders the 
amount of foreign income taxes paid by the portfolio, but may do so only if 
more than 50% of the value of the total assets of the portfolio at the end of 
the fiscal year is represented by foreign securities. These portfolios will 
make such an election only if they deem it to be in the best interests of 
their shareholders. The other portfolios will not be able to make this 
election. 

If this election is made, shareholders of the portfolio will be required to: 
(i) include in gross income, even though not actually received, their 
respective pro rata share of foreign taxes paid by the portfolio; (ii) treat 
their pro rata share of foreign taxes as paid by them; and (iii) either 
deduct their pro rata share of foreign taxes in computing their taxable 
income or use it within the limitations set forth in the Internal Revenue 
Code as a foreign tax credit against U.S. income taxes (but not both). 

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

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

Special Tax Considerations for the Municipal and PA Municipal 
Portfolios: These portfolios intend to invest a sufficient portion of their 
assets in municipal bonds and notes so that each will qualify to pay 
exempt-interest dividends to shareholders. Such exempt-interest dividends are 
excluded from a shareholder's gross income for Federal income tax purposes. 
Tax-exempt dividends received from the Municipal and PA Municipal Portfolios 
may be subject to state and local taxes. However, some states allow 
shareholders to exclude that portion of a portfolio's tax-exempt income which 
is attributable to municipal securities issued within the shareholder's state 
of residence. Furthermore, the PA Municipal Portfolio invests at least 65% of 
its assets in PA Municipals. As a result, the income of the portfolio that is 
derived from PA Municipals and U.S. Governments will not be subject to the 
Pennsylvania personal income tax or to the Philadelphia School District 
investment net income tax. Distributions by the PA Municipal Portfolio to a 
Pennsylvania resident that are attributable to most other sources may be 
subject to the Pennsylvania personal income tax and (for residents of 
Philadelphia) to the Philadelphia School District investment net income tax.

MAS Funds - 60      Terms in bold type are defined in the Prospectus Glossary
<PAGE>

To the extent, if any, that dividends paid to shareholders of the Municipal 
and PA Municipal Portfolios are derived from taxable interest or long-term or 
short-term capital gains, such dividends will be subject to Federal personal 
income tax (whether such dividends are paid in cash or in additional shares) 
and may also be subject to state and local taxes. In addition, the Municipal 
and PA Municipal Portfolios may invest in private activity municipal 
securities, the interest on which is subject to the Federal alternative 
minimum tax for corporations and individuals and the Federal environmental 
tax for corporations only. Exempt-interest dividends from such private 
activity securities issued after August 7, 1986, will generally be an item of 
tax preference and therefore potentially subject to the alternative minimum 
tax environmental tax. A shareholder may lose the tax exempt status of the 
accrued income of these portfolios if they redeem their shares before a 
dividend has been declared. 

The Municipal and PA Municipal Portfolios may not be appropriate investments 
for persons who are "substantial users" (or persons related to "substantial 
users") of facilities financed by industrial development bonds or private 
activity bonds. Such persons should consult their tax advisers before 
purchasing shares. 

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 the Morgan Stanley 
Group, Inc., and is located at One Tower Bridge, West Conshohocken, PA 19428. 
Miller Anderson & Sherrerd, LLP is an Equal Opportunity/Affirmative Action 
Employer. The Adviser provides investment services to employee benefit plans, 
endowment funds, foundations and other institutional investors and as of the 
date of this prospectus had in excess of $40.9 billion in assets under 
management.

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

- --------------------------------------------------------------------------------
MAS Funds - 66      Terms in bold type are defined in the Prospectus Glossary
<PAGE>

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 than the lowest available when the Adviser believes 
it is reasonable to do so in light of the value of the research, statistical, 
and pricing services provided by the broker effecting the transaction. 

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

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

OTHER INFORMATION: Description of Shares and Voting Rights: The Fund was 
established under Pennsylvania law by a Declaration of Trust dated February 
15, 1984, as amended and restated as of November 18, 1993. The Fund is

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 
Investment Company Act of 1940, as amended, 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.

                            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 persons
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.

this Prospectus operates as a separate diversified investment company. The
investment objective of each portfolio is described with a summary of investment
policies as referenced below. This Prospectus offers the Investment Class Shares
of the Fund. The Fund also offers Adviser Class Shares and Institutional Class
Shares.

Shares of the Cash Reserves Portfolio are neither insured nor guaranteed by the

The High Yield Portfolio will invest primarily, and certain other portfolios of

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.

EXPENSE SUMMARY - INVESTMENT CLASS SHARES 


The following tables illustrate the various expenses and fees that a 
shareholder for that portfolio will incur either directly or indirectly. The 
annual expenses and fees set forth below are estimated based upon the 
portfolios attaining certain average asset levels. The Adviser may from time 
to time waive fees or reimburse expenses thereby reducing total operating 
expenses. 
                    Shareholder Transaction Expenses: 
                    Sales Load Imposed on Purchases               None 
                    Sales Load Imposed on Reinvested Dividends    None 
                    Redemption Fees                               None 
                    Exchange Fees                                 None 


                    Annual Fund Operating Expenses: 
                    (as a percentage of average net assets after fee 
                    waivers) 
                    12b-1 Fees                                    None

Special Purpose Fixed Income     0.375*               0.155          0.680

Multi-Asset-Class                0.570*+              0.330          1.050 

</TABLE>


 Where applicable as described in Financial Highlights, the Total Operating 
 Expense ratios reflected in the table above are higher than the ratio of 
 expenses actually deducted from portfolio assets because of the effect of 
 expense offset arrangements. The result of such arrangements is to offset 
 expenses that otherwise would be deducted from portfolio assets. 

+ On November 21, 1996 shareholders of the Multi-Asset-Class Portfolio 
  approved an increase in the Advisory Fee from 0.45% to 0.65% of average 
  daily net assets. The Investment Advisory Fees and Total Operating Expenses 
  have been adjusted to reflect this change. 

* The Advisor has voluntarily agreed to waive Advisory Fees and/or reimburse 
  certain other expenses to the extent necessary to keep the Total Operating 
  Expenses of the Equity, Mid Cap Value, Value, Cash Reserves, High Yield, 
  Special Purpose Fixed Income and Multi-Asset-Class Portfolios from 
  exceeding 0.800%, 1.100%, 0.800%, 0.550%, 0.700%, 0.680% and 1.050%, 
  respectively. 

  Absent such fee waivers and/or reimbursements the Total Operating Expenses 
  would be 0.900%, 1.286%, 0.870%, 0.645%, 0.755%, 0.775% and 1.130%, for the 
  Equity, Mid Cap Value, Value, Cash Reserves, High Yield, Special Purpose 
  Fixed Income and Multi-Asset-Class Portfolios, respectively.

EXAMPLE 

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

EQUITY PORTFOLIOS 

Equity - seeks to achieve above-average total return over a market cycle of

in a diversified portfolio of Common Stocks of companies which are deemed by 
the Adviser to have earnings growth potential greater than the economy in 
general and greater than the expected rate of inflation. 

International Equity - seeks to achieve above-average total return over a 
market cycle of three to five years, consistent with reasonable risk, by 
investing primarily in a diversified portfolio of Foreign Equities. 

Mid Cap Value - seeks 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. 

Value - seeks to achieve above-average total return over a market cycle of 
three to five years, consistent with reasonable risk, by investing primarily 
in a diversified portfolio of Common Stocks which are deemed by the Adviser 
to be relatively undervalued based on various measures such as price/earnings 
ratios and price/book ratios. 

FIXED-INCOME PORTFOLIOS 

Cash Reserves - seeks to realize maximum current income, consistent with 
preservation of capital and liquidity, by investing in a diversified 
portfolio of money-market instruments, Cash Equivalents and other short-term 
securities having expected maturities of thirteen months or less. The 
portfolio seeks to maintain, but does not guarantee, a constant net asset 
value of $1.00 per share. 

Fixed Income - seeks to achieve above-average total return over a market 
cycle of three to five years, consistent with reasonable risk, by investing 
primarily in a diversified portfolio of U.S. Governments, Corporates, 
Mortgage Securities, Foreign Bonds and other Fixed-Income Securities and 
Derivatives. The portfolio's average weighted maturity will ordinarily exceed 
five years. 

High Yield - seeks to achieve above-average total return over a market cycle 
of three to five years, consistent with reasonable risk, by investing 
primarily in a diversified portfolio of High Yield Securities, Corporates and 
other Fixed-Income Securities (including bonds rated below investment grade) 
and Derivatives. The portfolio's average weighted maturity will ordinarily 
exceed five years. 

Special Purpose Fixed Income - seeks to achieve above-average total return 
over a market cycle of three to five years, consistent with reasonable risk, 
by investing primarily in a diversified portfolio of U.S. Governments, 
Corporates, Mortgage Securities, Foreign Bonds and other Fixed-Income 
Securities and Derivatives. The portfolio is structured to complement an 
investment in one or more of the Fund's Equity Portfolios for investors 
seeking a balanced investment. The portfolio's average weighted maturity will 
ordinarily exceed five years. 

BALANCED INVESTING 

Balanced Portfolio - seeks to achieve above-average total return over a 
market cycle of three to five years, consistent with reasonable risk, by 
investing in a diversified portfolio of Equity Securities, Fixed-Income 
Securities and Derivatives. When the Adviser judges the relative outlook for 
the equity and fixed-income markets to be neu- 

- --------------------------------------------------------------------------------
MAS Funds - 4          Terms in bold type are defined in the Prospectus Glossary

<PAGE>

tral, the portfolio will be invested 60% in equity securities and 40% in 
fixed-income securities. The asset mix is actively managed by the Adviser, 
with equity securities ordinarily representing between 45% and 75% of the 
total investment. The average weighted maturity of the fixed-income portion 
of the portfolio will ordinarily be greater than five years. 


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


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

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

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


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

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


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

o  Each portfolio (except the Cash Reserves Portfolio) may invest 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; 


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


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

<PAGE>

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


HOW TO INVEST: Investment Class Shares of each portfolio are available to 
Shareholders with combined investments of $1,000,000 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 Institutional and Adviser Class Shares which 
differ from the Investment 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). 
When considering average total return figures for periods longer than one 
year, it is important to note that a portfolio's annual total return for any 
one year in the period might have been greater or less than the average for 
the entire period. 

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

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

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

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

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

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

GENERAL INFORMATION: 

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

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

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

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

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


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

With respect to the Fixed Income Portfolios and the fixed-income portion of 
the Balanced and Multi-Asset-Class Portfolios, the annual turnover rate will 
ordinarily exceed 100% due to changes in portfolio duration, yield curve 
strategy or commitments to forward delivery mortgage-backed securities. 

Portfolio turnover rates for certain portfolios are as follows: Mid Cap Value 
- - 377%, Fixed Income - 162%, High Yield - 115%, Special Purpose Fixed Income 
- - 151%, Balanced - 110% and Multi-Asset-Class - 122%. 


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

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


Concentration: Concentration is defined as investment of 25% or more of a 
portfolio's total assets in the securities of issuers operating in any one 
industry. Except as provided in a portfolio's specific investment policies 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. 


(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. 

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

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

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

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

(g) a portfolio will not invest its assets in securities of any Investment 
Company, except as permitted by the 1940 Act or the rules, regulations, 
interpretations or orders of the SEC and its staff thereunder. 

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

Equity Portfolio 

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

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

Policies:                  Generally at least 65% invested in Equity 
                           Securities 
                           Up to 5% invested in Foreign Equities

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. 

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


Capitalization Range:      Generally matching the S&P MidCap 400 Index 
                           (currently $500 million to $6 billion)

Value Portfolio 

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

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

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

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

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 (including bonds rated below 
                           investment grade, commonly referred to as junk

                           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.

                           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

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 
                           Derivatives may be used to pursue portfolio

Multi-Asset-Class 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 of United States 
                           and Foreign issuers. 

Approach:                  The Adviser determines the mix of investments

                           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.

                             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 
MAS's outlook for the economy and different market sectors, the mix between 
value stocks and growth stocks will change. 

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

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

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


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


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

<PAGE>

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

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


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

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


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

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

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

   The market for high yield securities is still relatively new. Because of 
this, a long-term track record for bond default rates does not exist. In 
addition, the secondary market for high yield securities is generally less 
liquid than that for investment grade corporate securities. In periods of 
reduced market liquidity, high yield bond prices may become more volatile, 
and both the high yield market and a portfolio may experience sudden and 
substantial price declines. This lower liquidity might have an effect on a 
portfolio's ability to value or dispose of such securities. Also, there 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 coupon bonds pay interest only at maturity and payment-in-kind 
bonds pay interest in the form of additional securities. Payment in the form 
of additional securities, or interest income recognized through discount 
accretion, will, however, be treated as ordinary income which will be 
distributed to shareholders even though the portfolio does not receive 
periodic cash flow from these investments. 


   The following table 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 for the fiscal year ended September 30, 1996. (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.

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

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

Maturity and Duration Management: One of two primary components of the 
Adviser's fixed-income investment strategy is maturity and duration 
management. The maturity and duration structure of a portfolio investing in 
Fixed-Income Securities is actively managed in anticipation of cyclical 
interest rate changes. Adjustments are not made in an effort to capture 
short-term, day-to-day movements in the market, but instead are implemented 
in 

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

<PAGE>

anticipation of longer term shifts in the levels of interest rates. 
Adjustments made to shorten portfolio maturity and duration are made to limit 
capital losses during periods when interest rates are expected to rise. 
Conversely, adjustments made to lengthen maturity are intended to produce 
capital appreciation in periods when interest rates are expected to fall. The 
foundation for maturity and duration strategy lies in analysis of the U.S. 
and global economies, focusing on levels of real interest rates, monetary and 
fiscal policy actions, and cyclical indicators. See Value Investing for a 
description of the second primary component of the Adviser's fixed-income 
strategy. 

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

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

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

Money Market Investing: A money market fund like the Cash Reserves Portfolio 
invests in securities which present minimal credit risk and may not yield as 
high a level of current income as securities of lower quality or longer 
maturities which generally have less liquidity, greater market risk and more 
price fluctuation. A money market portfolio is designed to provide maximum 
principal stability for investors seeking to invest funds for the short- 
term, or, for investors seeking to combine a long-term investment program in 
other portfolios of the Fund with an investment in money market instruments. 
However, because the Cash Reserves Portfolio invests in the money market 
obligations of private financial and non-financial corporations in addition 
to those of the U.S. Government or its agencies and instrumentalities, it 
offers higher credit risk and yield potential relative to money market funds 
which invest exclusively in U.S. Government securities. The Cash Reserves 
Portfolio seeks to maintain, but does not guarantee, a constant net asset 
value of $1.00 per share. 

Mortgage Investing: At times it is anticipated that greater than 50% of a 
fixed-income portfolio's assets may be invested in mortgage-related 
securities. These include mortgage-backed securities, which represent 
interests in pools of mortgage loans made by lenders such as commercial 
banks, savings and loan associations, mortgage bankers and others. The pools 
are assembled by various organizations, including the Government National 
Mortgage Association (GNMA), Federal Home Loan Mortgage Corporation (FHLMC), 
Federal National Mortgage Association (FNMA), other government agencies, and 
private issuers. It is expected that a portfolio's primary emphasis will be 
on mortgage-backed securities issued by the various Government-related 
organizations. However, a portfolio may 

- --------------------------------------------------------------------------------
MAS Funds - 26         Terms in bold type are defined in the Prospectus Glossary

<PAGE>

invest, without limit, in mortgage-backed securities issued by private 
issuers when the Adviser deems that the quality of the investment, the 
quality of the issuer, and market conditions warrant such investments. 
Securities issued by private issuers will be rated investment grade by 
Moody's or Standard & Poor's or be deemed by the Adviser to be of comparable 
investment quality. 

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

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 Depositary 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 addition the 
short-term nature of the loans reduces the impact of any change in prepayment 
level. Due to amortization, the average life for these securities is also the 
conventional proxy for maturity. 

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

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

<PAGE>

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

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

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

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


(2) Each portfolio (except Cash Reserves) may invest in commercial paper 
rated at time of purchase by one or more 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; 


(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, Federal 
National Mortgage Association, Federal Financing Bank, the Tennessee Valley 
Authority, and others; 


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

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


CMOs--Collateralized Mortgage Obligations: are Derivatives which are 
collateralized by mortgage pass-through securities. Cash flows from the 
mortgage pass-through securities are allocated to various tranches (a 
"tranche" is essentially a separate security) in a predetermined, specified 
order. Each tranche has a stated maturity - the latest date by which the 
tranche can be completely repaid, assuming no prepayments - and has an 
average life - the aver 

- --------------------------------------------------------------------------------
MAS Funds - 28         Terms in bold type are defined in the Prospectus Glossary

<PAGE>

age of the time to receipt of a principal payment weighted by the size of the 
principal payment. The average life is typically used as a proxy for maturity 
because the debt is amortized (repaid a portion at a time), rather than being 
paid off entirely at maturity, as would be the case in a straight debt 
instrument. 

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


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


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

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


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

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. 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. All of 
the portfolios of MAS Funds, except the Cash Reserves Portfolio, may enter 
into over-the-counter Derivatives transactions (Swaps, Caps, Floors, Puts, 
etc., but excluding CMOs, Forwards, Futures and Options, and SMBS) with 
counterparties approved by MAS in accordance with guidelines established by 
the Board of Trustees. These guidelines provide for a minimum credit rating 
for each counterparty and various credit enhancement techniques (for example, 
collateralization of amounts due from counterparties) to limit exposure to 
counterparties with ratings below AA. Derivatives include, but are not 
limited to, CMOs, Forwards, Futures and Options, SMBS, Structured 
Investments, Structured Notes and Swaps. See each individual Portfolio's 
listing of Allowable Investments to determine which of these the Portfolio 
may hold.

Eastern European Issuers: The economies of Eastern European countries are 
currently suffering both from the stagnation resulting from centralized 
economic planning and control and the higher prices and unemployment 
associated with the transition to market economics. Unstable economic and 
political conditions may adversely affect security values. Upon the accession 
to power of Communist regimes 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. In the event of the return to power of the Communist Party, there 
can be no assurance that the portfolio's investments in Eastern Europe would 
not be expropriated, nationalized or otherwise confiscated. 


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


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

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


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

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

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


Foreign Equities: are Common Stock, Preferred Stock, Rights and Warrants of 
foreign issuers denominated in foreign currency and traded primarily in 
non-U.S. markets. 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).

<PAGE>


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 those transactions create residual foreign 
currency exposure. When a portfolio enters into a forward contract for 
purposes of creating a position hedge, transaction hedge, cross hedge, or a 
synthetic security, it will generally be required to hold liquid securities 
or cash in a segregated account with a daily value at least equal to its 
obligation under the forward contract. 


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

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

Possible Risks: The primary risks associated with the use of futures and 
options are (i) imperfect correlation between the change in market value of 
the securities held by a portfolio and the prices of futures and options 
relating to the stocks, bonds or futures contracts purchased or sold by a 
portfolio; and (ii) possible lack of a liquid secondary market for a futures 
contract and the resulting inability to close a futures position which could 
have an adverse impact on a portfolio's ability to execute futures and 
options strategies. Additional risks associated with options transactions are 
(i) the risk that an option will expire worthless; (ii) the risk that the 
issuer of an over-the- 

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 31

<PAGE>

counter option will be unable to fulfill its obligation to the portfolio due 
to bankruptcy or related circumstances; (iii) the risk that options may 
exhibit greater short-term price volatility than the underlying security; and 
(iv) the risk that a portfolio may be forced to forego participation in the 
appreciation of the value of underlying securities, futures contracts or 
currency due to the writing of a call option. 

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

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

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

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

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

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

Investment Companies: The portfolios are permitted to invest in shares of 
other open-end or closed-end investment companies. The Investment Company Act 
of 1940, as amended, generally prohibits the portfolios from acquiring more 
than 3% of the outstanding voting shares of an investment company and limits 
such investments to 

- --------------------------------------------------------------------------------
MAS Funds - 32         Terms in bold type are defined in the Prospectus Glossary

<PAGE>

no more than 5% of the portfolio's total assets in any one investment company 
and no more than 10% in any combination of investment companies. The 1940 Act 
also prohibits the portfolios from acquiring in the aggregate more than 10% 
of the outstanding voting shares of any registered closed-end investment 
company. 

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

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


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


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

Mortgage Securities--Mortgage-backed securities represent an ownership 
interest in a pool of residential and commercial mortgage loans. Generally, 
these securities are designed to provide monthly payments of interest and 
principal to the investor. The mortgagee's monthly payments to his/her 
lending institution are passed through to investors such as the portfolio. 
Most issuers or poolers provide guarantees of payments, regardless of whether 
the mortgagor actually makes the payment. The guarantees made by issuers or 
poolers are supported by various forms of credit, collateral, guarantees or 
insurance, including individual loan, title, pool and hazard insurance 
purchased by the issuer. The pools are assembled by various Governmental, 
Government-related and private organizations. Portfolios may invest in 
securities issued or guaranteed by the Government National Mortgage 
Association (GNMA), Federal Home Loan Mortgage Corporation (FHLMC), Federal 
National Mortgage Association (FNMA), private issuers and other government 
agencies. There can be no assurance that the private insurers can meet their

<PAGE>


obligations under the policies. Mortgage-backed securities issued by 
non-agency issuers, whether or not such securities are subject to guarantees, 
may entail greater risk. If there is no guarantee provided by the issuer, 
mortgage- backed securities purchased by the portfolio will be those which at 
time of purchase are rated investment grade by one or more NRSRO, or, if 
unrated, are deemed by the Adviser to be of investment grade quality. 


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


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

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


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

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

Municipal notes are issued to meet the short-term funding requirements of 
local, regional and state governments. Municipal notes include bond 
anticipation notes, revenue anticipation notes and tax and revenue 
anticipation notes. These are short-term debt obligations issued by state and 
local governments to aid cash flows while waiting for taxes or revenue to be 
collected, at which time the debt is retired. Other types of municipal notes 
in which the portfolio may invest are construction loan notes, short-term 
discount notes, tax-exempt commercial paper, demand notes, and similar 
instruments. Demand notes permit an investor (such as the portfolio) to 
demand from the issuer payment of principal plus accrued interest upon a 
specified number of days' notice. The portfolios eligible to pur- 

- --------------------------------------------------------------------------------
MAS Funds - 34         Terms in bold type are defined in the Prospectus Glossary

<PAGE>

chase 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. 

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


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

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

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


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


SMBS are usually structured with two classes that receive different 
proportions of the interest and principal distributions on a pool of mortgage 
assets. One type of SMBS will have one class receiving some of the interest 
and most of the principal from the mortgage assets, while the other class 
will receive most of the interest and the remainder of the principal. In some 
cases, one class will receive all of the interest (the 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 Investment Company Act of 1940. A 
trust unit pays a return based on the total return of securities and other 
investments held by the trust and the trust may enter into one or more Swaps 
to achieve its objective. For example, a trust may purchase a basket of 
securities and 

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 35
<PAGE>


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


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


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

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

Possible Risks: Interest rate and total rate of return swaps do not involve 
the delivery of securities, other underlying assets, or principal. 
Accordingly, the risk of loss with respect to interest rate and total rate of 
return swaps is limited to the net amount of interest payments that a 
portfolio is contractually obligated to make. If the other party to an 
interest rate or total rate of return swap defaults, a portfolio's risk of 
loss consists of the net amount of interest payments that a portfolio is 
contractually entitled to receive. In contrast, currency swaps 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. 

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.

<PAGE>


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. 


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

GENERAL SHAREHOLDER INFORMATION 

                              PURCHASE OF SHARES 


Investment Class Shares are available to Shareholders with combined 
investments of $1,000,000 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. 


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


The Cash Reserves Portfolio declares dividends daily and, therefore, at the 
time of a purchase must have funds immediately available for investment. As a 
result, payment for the purchase of shares must be in the form of Federal 
Funds (monies credited to the portfolio's Custodian by a Federal Reserve 
Bank) before they can be accepted by the portfolio. The portfolio is credited 
with Federal Funds on the same day if the investment is made by Federal Funds 
Wire. Investment 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 MAS Funds' completing and signing an Account Registration Form 
(provided at the end of the prospectus) and mailing it to the MAS Funds' 
Client Services Group, c/o Miller Anderson & Sherrerd, LLP, One Tower Bridge, 
West Conshohocken, Pennsylvania 19428-0868 together with a check ($1,000,000 
minimum) payable to MAS Funds. 

The portfolio(s) 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 purchases made 
by check in any portfolio are not permitted to be redeemed until payment of 
the purchase has been collected, which may take up to eight business days 
after purchase. Shareholders can avoid this delay by purchasing shares by 
wire.

<PAGE>


Initial Purchase by Wire: Subject to acceptance by the Fund, Investment Class 
Shares may also be purchased by wiring Federal Funds ($1,000,000 minimum) 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. Investment 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 
                               New York, NY 10081

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


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


Additional Investments: Additional investments of Investment Class Shares may 
be made at any time (minimum investment $1,000) by mailing a check (payable 
to MAS Funds) to MAS Funds' Client Services Group at the address noted under 
Initial 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 Investment Class Shares of any of its 
portfolios or to reject any purchase orders when, in the judgment of 
management, such suspension or rejection is in the best interest of the Fund. 
The Fund also reserves the right, in its sole discretion, to waive the 
minimum initial and subsequent investment amounts. 

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

Investment Class Shares of the Fund's portfolios may be 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 Investment Class Shares though 
Shareholder Organizations may receive a fee for providing shareholder 
services to their clients who hold Investment Class Shares.

                             REDEMPTION OF SHARES 


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

By Mail: Each portfolio will redeem Investment Class Shares at the net asset 
value next determined after the request is received in good order. Requests 
should be addressed to MAS Funds, c/o 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. 

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 NYSE, the Custodian, or the Fund is closed (see Other 
Information-Closed Holidays) or under any emergency circumstances as 
determined by the Securities and Exchange Commission. 

If the Board of Trustees determines that it would be detrimental to the best 
interests of the remaining shareholders of the Fund to make payment wholly or 
partly in cash, the Fund may pay the redemption proceeds in whole or in

part by a distribution in-kind of readily marketable securities held by a 
portfolio in lieu of cash in conformity with applicable rules of the 
Securities and Exchange Commission. Investors may incur brokerage charges on 
the sale of portfolio securities received in such payments of redemptions. 

                             SHAREHOLDER SERVICES 


Exchange Privilege: Each portfolio's Investment Class Shares may be exchanged 
for Investment Class Shares of the Fund's other portfolios offering 
Investment 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 registered for sale in a shareholder's state 
of residence. There are no exchange fees. Exchange requests should be sent to 
MAS Funds, c/o 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 


Equity, International Equity, Mid 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 value of other assets and securities 
for which no quotations are readily available (including restricted 
securities) are determined in good faith at fair value using methods approved 
by the Trustees. 

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

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

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

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

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

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

The Trustees have also agreed to establish procedures reasonably designed, 
taking into account current market conditions and the portfolio's investment 
objective, to stabilize the net asset value per share as computed for the 
purposes of sales and redemptions at $1.00. These procedures include periodic 
review, as the Trustees deem appropriate and at such intervals as are 
reasonable in light of current market conditions, of the relationship between 
the amortized cost value per share and a net asset value per share based upon 
available indications of market value. In such a review, investments for 
which market quotations are readily available are valued at the most recent 
bid price or quoted yield equivalent for such securities or for securities of 
comparable maturity, quality and type as obtained from one or more of the 
major market makers for the securities to be valued. Other investments and 
assets are valued at fair value, as determined in good faith by the Trustees.

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

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

o  The Equity, Value, Fixed Income, Special Purpose Fixed Income, High Yield, 
   Balanced and Multi-Asset-Class Portfolios normally distribute 
   substantially all of their net investment income to shareholders in the 
   form of quarterly dividends. 

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

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

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

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

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

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

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


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.

<PAGE>

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


Federal Taxes: The following summary of Federal income tax consequences 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 federal income tax treatment of the 
portfolio or its shareholders. In addition, state and local tax consequences 
of an investment in the portfolio may differ from the Federal income tax 
consequences described below. Accordingly, shareholders are urged to consult 
their tax advisers regarding specific questions as to federal, state and 
local taxes. 

Each portfolio of the Fund intends to qualify for taxation as a regulated 
investment company under the Internal Revenue Code of 1986 (the "Code") so 
that each portfolio will not be subject to Federal income tax to the extent 
it distributes net investment company taxable income and net capital gains 
(the excess of net long-term capital gain over net short-term capital loss) 
to shareholders. Each Portfolio is treated as a separate entity for Federal 
income tax purposes and is not combined with any of the Funds' other 
portfolios. Dividends, either in cash or reinvested in shares, paid by a 
portfolio from net investment income will be taxable to shareholders as 
ordinary income. In the case of the Equity, Value, Balanced, 
Multi-Asset-Class and Mid Cap Value Portfolios, such dividends paid to 
corporate shareholders will generally qualify in part for the dividends 
received deduction for corporations to the extent attributable to dividends 
received by such portfolios from domestic corporations. The Fund will send 
each shareholder of such portfolios a statement each year indicating the 
amount of the dividend income which qualifies for such treatment. 

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


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


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


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

Foreign Income Taxes: Investment income received by the portfolios from 
sources within foreign countries may be subject to foreign income taxes 
withheld at the source. The U.S. has entered into Tax Treaties with many 
foreign countries which entitle these portfolios to a reduced rate of tax or 
exemption from tax on such income. It is impossible to determine the 
effective rate of foreign tax in advance since the amount of the portfolios' 
assets to be invested within various countries is not known. The portfolios 
intend to operate so as to qualify for treaty reduced rates of tax where 
applicable.

<PAGE>


The International Equity Portfolio may file an election with the Internal 
Revenue Service to pass through to the portfolio's shareholders the amount of 
foreign income taxes paid by the portfolio, but may do so only if more than 
50% of the value of the total assets of the portfolio at the end of the 
fiscal year is represented by foreign securities. The portfolio will make 
such an election only if it is deemed to be in the best interests of the 
shareholders. The other portfolios will not be able to make this election. 

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


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


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


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 the Morgan Stanley 
Group, Inc., and is located at One Tower Bridge, West Conshohocken, PA 19428. 
Miller Anderson & Sherrerd, LLP is an Equal Opportunity/Affirmative Action 
Employer. The Adviser provides investment services to employee benefit plans, 
endowment funds, foundations and other institutional investors and as of the 
date of this prospectus had in excess of $40.9 billion in assets under 
management. 

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

* Advisory fees in excess of 0.750% of average net assets are considered 
  higher than normal for most investment companies, but are not unusual for 
  portfolios that invest primarily in small capitalization stocks. 

Until further notice, the Adviser has voluntarily agreed to waive advisory 
fees and/or reimburse certain other expenses to the extent necessary to keep 
Total Operating Expenses actually deducted from portfolio assets for the 
Investment Class of the Equity, Mid Cap Value, Value, Cash Reserves, High 
Yield, Special Purpose Fixed Income and Multi-Asset-Class Portfolios from

purchase Investment Class Shares. For this service, such Service Providers 
are compensated at an annual rate of .15% of the average net assets of the 
Investment Class Shares of each Portfolio. Fees paid pursuant to the Service 
Plan are separate fees of the Investment Class Shares of each Portfolio and 
will reduce the net investment income and total return of the Investment 
Class Shares of these Portfolios.

<PAGE>

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 than the lowest available when the Adviser believes 
it is reasonable to do so in light of the value of the research, statistical, 
and pricing services provided by the broker effecting the transaction. 

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

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

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

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

Meetings of shareholders will not be held except as required by the 
Investment Company Act of 1940, as amended, 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 2, 1997, The Northern Trust Co. (Chicago, IL) owned a 
controlling interest (as that term is defined by the Investment Company Act 
of 1940, as amended) of the Cash Reserves Portfolio; Wendell & Co. (New York, 
NY) owned a controlling interest of the Balanced Portfolio.

- -------------------------------------------------------------------------------
                            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 persons
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.

MAS Funds (the Fund) is a no-load mutual fund consisting of twenty-six
portfolios, six of which are described in this Prospectus. Each portfolio in
this Prospectus operates as a separate diversified investment company. The
investment objective of each portfolio is described with a summary of investment
policies as referenced below. This Prospectus offers the Adviser Class Shares of
the Fund. The Fund also offers Institutional Class Shares and Investment Class
Shares.
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
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.

EXPENSE SUMMARY - ADVISER CLASS SHARES

The following tables illustrate the various expenses and fees that a 
shareholder for that portfolio will incur either directly or indirectly. The 
annual expenses and fees set forth below are estimated based upon the 
portfolios attaining certain average asset levels. The Adviser may from time 
to time waive fees or reimburse expenses thereby reducing total operating 
expenses. 
                    Shareholder Transaction Expenses: 
                    Sales Load Imposed on Purchases                None 
                    Sales Load Imposed on Reinvested Dividends     None 
                    Redemption Fees                                None 
                    Exchange Fees                                  None 

                    Annual Fund Operating Expenses: 
                    (as a percentage of average net assets after 
                    fee waivers)

</TABLE>

Where applicable as described in Financial Highlights, the Total Operating 
Expense ratios reflected in the table above are higher than the ratio of 
expenses actually deducted from portfolio assets because of the effect of 
expense offset arrangements. The result of such arrangements is to offset 
expenses that otherwise would be deducted from portfolio assets. 

* The Adviser has voluntarily agreed to waive advisory fees and/or reimburse 
certain other expenses, to the extent necessary, to keep the Total Operating 
Expenses from exceeding, 0.900% and 0.700% for the Value and Limited Duration 
Portfolios, respectively. Absent such waivers or reimbursements the Total 
Operating Expenses would be 0.940% for the Value Portfolio. There are no such 
waivers or reimbursements for the Limited Duration Portfolio.

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. Long-term shareholders may 
eventually pay more than the economic equivalent of the maximum front-end 
sales charge otherwise permitted by the Rules of Fair Practice of the 
National Association of Securities Dealers, Inc.

PROSPECTUS SUMMARY


EQUITY PORTFOLIOS 

   Mid Cap Growth - seeks to achieve long-term capital growth by investing 
primarily in a diversified portfolio of Common Stocks of smaller and medium 
size companies that are deemed by the Adviser to offer long-term growth 
potential. 

   Value - seeks to achieve above-average total return over a market cycle of 
three to five years, consistent with reasonable risk, by investing primarily 
in a diversified portfolio of Common Stocks which are deemed by the Adviser 
to be relatively undervalued based on various measures such as price/earnings 
ratios and price/book ratios. 

FIXED-INCOME PORTFOLIOS 

   Fixed Income - seeks to achieve above-average total return over a market 
cycle of three to five years, consistent with reasonable risk, by investing 
primarily in a diversified portfolio of U.S. Governments, Corporates, 
Mortgage Securities, Foreign Bonds and other Fixed-Income Securities and 
Derivatives. The portfolio's average weighted maturity will ordinarily exceed 
five years. 

   High Yield - seeks to achieve above-average total return over a market 
cycle of three to five years, consistent with reasonable risk, by investing 
primarily in a diversified portfolio of High Yield Securities, Corporates and 
other Fixed-Income Securities (including bonds rated below investment grade) 
and Derivatives. The portfolio's average weighted maturity will ordinarily 
exceed five years. 

   Limited Duration - seeks to achieve above-average total return over a 
market cycle of three to five years, consistent with reasonable risk, by 
investing primarily in a diversified portfolio of U.S. Governments, Mortgage 
Securities, investment-grade Corporates and other Fixed-Income Securities. 
The portfolio will maintain an average duration of between one and three 
years. 

BALANCED INVESTING 

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

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

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

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

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

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

o  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; and 

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

YIELD AND TOTAL RETURN

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

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

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

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

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

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

GENERAL INFORMATION

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

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

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

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 in securities that are illiquid by virtue of the 
absence of a readily available market, or because of legal or contractual 
restrictions on resale. This policy does not limit the acquisition of (i) 
restricted securities eligible for resale to qualified institutional buyers 
pursuant to Rule 144A under the Securities Act of 1933 or (ii) commercial 
paper issued pursuant to Section 4(2) under the Securities Act of 1933, that 
are determined to be liquid in accordance with guidelines established by the 
Fund's Board of Trustees. 

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

With respect to the Fixed Income Portfolio and the fixed-income portion of 
the Balanced Portfolio, the annual turnover rate will ordinarily exceed 100% 
due to changes in portfolio duration, yield curve strategy or commitments to 
forward delivery mortgage-backed securities. 

Portfolio turnover rates for certain portfolios as of September 30, 1996 
were: Mid Cap Growth - 141%, Fixed Income - 162%, High Yield - 115%, Limited 
Duration - 174% and Balanced - 110%. 

High rates of portfolio turnover necessarily result in correspondingly 
heavier brokerage and portfolio trading costs which are paid by a portfolio. 
Trading in Fixed-Income Securities does not generally involve the payment of 
bro-

<PAGE>

kerage commissions, but does involve indirect transaction costs. In addition 
to portfolio trading costs, higher rates of portfolio turnover may result in 
the realization of capital gains. To the extent net short-term capital gains 
are realized, any distributions resulting from such gains are considered 
ordinary income for federal income tax purposes. 

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

Concentration: Concentration is defined as investment of 25% or more of a 
portfolio's total assets in the securities of issuers operating in any one 
industry. Except as provided in a portfolio's specific investment policies or 
as detailed in the 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. 

(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. 

(c) a portfolio will not acquire any securities of companies within one 
industry, if, as a result of such acquisition, more than 25% of the value of 
the portfolio's total assets would be invested in securities of companies 
within such industry; provided, however, that (1) there shall be no 
limitation on the purchase of obligations issued or guaranteed by the U.S. 
Government, its agencies or instrumentalities; (2) utility companies will be 
divided according to their services, for example, gas, gas transmission, 
electric and telephone will each be considered a separate industry; (3) 
financial service companies will be classified according to the end users of 
their services, for example, automobile finance, bank finance and diversified 
finance will each be considered a separate industry; and (4) asset-backed 
securities will be classified according to the underlying assets securing 
such securities; 

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

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

- --------------------------------------------------------------------------------
MAS Funds - 12         Terms in bold type are defined in the Prospectus Glossary
 
<PAGE>

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

(g) a portfolio will not invest its assets in securities of any investment 
company, except as permitted by the 1940 Act or the rules, regulations, 
interpretations or orders of the SEC and its staff thereunder. 

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

MID CAP GROWTH PORTFOLIO 

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

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

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

VALUE PORTFOLIO 

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

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

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

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 of domestic issuers and other 
                           fixed-income securities. The Portfolio's 
                           average weighted maturity will ordinarily be 
                           greater than five years. 

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. 

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

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 (including bonds rated below 
                           investment grade, commonly referred to as junk 
                           bonds) 
                           Derivatives may be used to pursue portfolio 
                           strategy

LIMITED DURATION PORTFOLIO 

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

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

Policies:                  Generally at least 65% invested in 
                           Fixed-Income Securities 
                           Derivatives may be used to pursue portfolio

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

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 
MAS's outlook for the economy and different market sectors, the mix between 
value stocks and growth stocks will change. 

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

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

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

   Fixed Income Management and Asset Allocation: Within the Balanced 
Portfolio, the Adviser selects fixed-income securities not only on the basis 
of judgments regarding Maturity and Duration Management and Value 

- --------------------------------------------------------------------------------
MAS Funds - 20         Terms in bold type are defined in the Prospectus Glossary

<PAGE>

Investing, but also on the basis of the value offered by various segments of 
the fixed-income securities market relative to Cash Equivalents and Equity 
Securities. In this context, the Adviser may find that certain segments of 
the fixed-income securities market offer more or less attractive relative 
value when compared to Equity Securities than when compared to other 
Fixed-Income Securities. 

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

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

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

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

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

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

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

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

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

   The market for high yield securities is still relatively new. Because of 
this, a long-term track record for bond default rates does not exist. In 
addition, the secondary market for high yield securities is generally less 
liquid than that for investment grade corporate securities. In periods of 
reduced market liquidity, high yield bond prices may become more volatile, 
and both the high yield market and a portfolio may experience sudden and 
substantial price declines. This lower liquidity might have an effect on a 
portfolio's ability to value or dispose of such securities. Also, there 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 coupon bonds pay interest only at maturity and payment-in-kind 
bonds pay interest in the form of additional securities. Payment in the form 
of additional securities, or interest income recognized through discount 
accretion, will, however, be treated as ordinary income which will be 
distributed to shareholders even though the portfolio does not receive 
periodic cash flow from these investments.

foreign debt holdings of those portfolios with more than 5% invested in High 
Yield securities as of September 30, 1996 (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%

</TABLE>

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

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

Duration is a measure of the expected life of a fixed-income security that 
was developed as a more precise alternative to the concept of 
term-to-maturity. Duration incorporates a bond's yield, coupon interest 
payments, final maturity and call features into one measure. Duration is one 
of the fundamental tools used by the Adviser in the selection of fixed-income 
securities. Duration is a measure of the expected life of a fixed-income 
security on a present value basis. Duration takes the length of the time 
intervals between the present time and the time that the interest and 
principal payments are scheduled or, in the case of a callable bond, expected 
to be received, and weights them by the present values of the cash to be 
received at each future point in time. For any fixed-income 

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 23

<PAGE>

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

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

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 Depositary Shares. 

- --------------------------------------------------------------------------------
MAS Funds - 24         Terms in bold type are defined in the Prospectus Glossary

<PAGE>

   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 addition the 
short-term nature of the loans reduces the impact of any change in prepayment 
level. Due to amortization, the average life for these securities is also the 
conventional proxy for maturity. 

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

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

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

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

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

   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 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); 

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

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

   (5) 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, Federal 
National Mortgage Association, Federal Financing Bank, the Tennessee Valley 
Authority, and others; and 

   (6) Repurchase agreements collateralized by securities listed above. 

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

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

   Like bonds in general, mortgage-backed securities will generally decline 
in price when interests 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. 

   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. 

- --------------------------------------------------------------------------------
MAS Funds - 26         Terms in bold type are defined in the Prospectus Glossary

<PAGE>

   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 type 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. 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. All of 
the portfolios may enter into over-the-counter Derivatives transactions 
(Swaps, Caps, Floors, Puts, etc., but excluding CMOs, Forwards, Futures and 
Options, and SMBS) with counterparties approved by MAS in accordance with 
guidelines established by the Board of Trustees. These guidelines provide for 
a minimum credit rating for each counterparty and various credit enhancement 
techniques (for example, collateralization of amounts due from 
counterparties) to limit exposure to counterparties with ratings below AA. 
Derivatives include, but are not limited to, CMOs, Forwards, Futures and 
Options, SMBS, Structured Notes and Swaps. See each individual Portfolio's 
listing of Allowable Investments to determine which of these the Portfolio 
may hold. 

   Eastern European Issuers: The economies of Eastern European countries are 
currently suffering both from the stagnation resulting from centralized 
economic planning and control and the higher prices and unemployment 
associated with the transition to market economics. Unstable economic and 
political conditions may adversely affect security values. Upon the accession 
to power of Communist regimes 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. In the event of the return to power of the Communist Party, there 
can be no assurance that the portfolio's investments in Eastern Europe would 
not be expropriated, nationalized or otherwise confiscated. 

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

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

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

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

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

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

   Foreign Equities: are Common Stock, Preferred Stock, Rights and Warrants 
of foreign issuers denominated in foreign currency and traded primarily in 
non-U.S. markets. 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 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 denomi- 

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

<PAGE>

nated 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 those transactions create residual foreign 
currency exposure. When a portfolio enters into a forward contract for 
purposes of creating a position hedge, transaction hedge, cross hedge, or a 
synthetic security, it will generally be required to hold liquid securities 
or cash in a segregated account with a daily value at least equal to its 
obligation under the forward contract. 

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

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

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

   High Yield: High yield securities are generally considered to be corporate 
bonds, preferred stocks, and convertible securities rated Ba through C by 
Moody's or BB through D by Standard & Poor's, and unrated securities con-

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

<PAGE>

sidered 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." C The rating C 
is reserved for income bonds on which "no interest is being paid." D - Debt 
rated D is in "default", and "payment of interest and/or repayment of 
principal is in arrears." 

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

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

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

Investment Companies: The portfolios that are permitted to invest in shares 
of other open-end or closed-end investment companies. The Investment Company 
Act of 1940, as amended, generally prohibits the portfolios from 

- --------------------------------------------------------------------------------
MAS Funds - 30         Terms in bold type are defined in the Prospectus Glossary

<PAGE>

acquiring more than 3% of the outstanding voting shares of an investment 
company and limits such investments to no more than 5% of the portfolio's 
total assets in any one investment company and no more than 10% in any 
combination of investment companies. The 1940 Act also prohibits the 
portfolios from acquiring in the aggregate more than 10% of the outstanding 
voting shares of any registered closed-end investment company. 

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

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

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

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

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

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

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

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

Municipals--Municipal Securities: are debt obligations issued by local, state 
and regional governments that provide interest income which is exempt from 
federal income taxes. Municipal securities include both municipal bonds 
(those securities with maturities of five years or more) and municipal notes 
(those with maturities of less than five 

- --------------------------------------------------------------------------------
MAS Funds - 32         Terms in bold type are defined in the Prospectus Glossary

<PAGE>

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. 

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

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

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

Pursuant to an order issued by the Securities and Exchange Commission, the 
Fund's portfolios may pool their daily uninvested cash balances in order to 
invest in repurchase agreements on a joint basis. By entering into repurchase 

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 33

<PAGE>

agreements on a joint basis, it is expected that the portfolios will incur 
lower transaction costs and potentially obtain higher rates of interest on 
such repurchase agreements. Each portfolio's participation in the income from 
jointly purchased repurchase agreements will be based on that portfolio's 
percentage share in the total purchase 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 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 
notional amount. 

- --------------------------------------------------------------------------------
MAS Funds - 34         Terms in bold type are defined in the Prospectus Glossary

<PAGE>

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

Possible Risks: Interest rate and total rate of return swaps do not involve 
the delivery of securities, other underlying assets, or principal. 
Accordingly, the risk of loss with respect to interest rate and total rate of 
return swaps is limited to the net amount of interest payments that a 
portfolio is contractually obligated to make. If the other party to an 
interest rate or total rate of return swap defaults, a portfolio's risk of 
loss consists of the net amount of interest payments that a portfolio is 
contractually entitled to receive. In contrast, currency swaps 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. 

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. 

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

Group at the address noted under Initial Investments by Mail or by wiring 
Federal Funds to the Custodian Bank as outlined above. Shares will be 
purchased at the net asset value per share next determined after receipt of 
the purchase order. For all portfolios, notification must be given to MAS 
Funds' Client Services Group at 1-800-354-8185 prior to the determination of 
net asset value. 

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

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

Adviser 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 may pay compensation to or receive compensation from Shareholder 
Organizations for the sale of Adviser Class Shares. 

REDEMPTION OF SHARES 

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

   By Mail: Each portfolio will redeem Adviser Class Shares at the net asset 
value next determined after the request is received in good order. Requests 
should be addressed to MAS Funds, c/o 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.

   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 NYSE, the Custodian, or the Fund is closed (see Other 
Information-Closed Holidays) or under any emergency circumstances as 
determined by the Securities and Exchange Commission. 

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

SHAREHOLDER SERVICES 

   Exchange Privilege: Each portfolio's Adviser Class Shares may be exchanged 
for shares of the Fund's other portfolios offering Adviser 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 
registered for sale in a shareholder's state of residence. There are no 
exchange fees. Exchange requests should be sent to MAS Funds, c/o 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 

Mid Cap Growth 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 value of other assets and securities 
for which no quotations are readily available (including restricted 
securities) are determined in good faith at fair value using methods approved 
by the Trustees. 

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

   However, bonds and other Fixed-Income Securities may be valued on the 
basis of prices provided by a pricing service when such prices are believed 
to reflect the fair market value of such securities. The prices provided by a 
pricing service are determined without regard to bid or last sale prices but 
take into account institutional size trading in similar groups of securities 
and any developments related to specific securities. Bonds and other Fixed- 
Income Securities not priced in this manner are valued at the most recent 
quoted bid price, or when stock exchange 

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 39

<PAGE>

valuations are used, at the latest quoted sale price on the day of valuation. 
If there is no such reported sale, the latest quoted bid price will be used. 
Securities purchased with remaining maturities of 60 days or less are valued 
at amortized cost when the Board of Trustees determines that amortized cost 
reflects fair value. In the event that amortized cost does not approximate 
market, market prices as determined above will be used. Other assets and 
securities, for which no quotations are readily available (including 
restricted securities), will be valued in good faith at fair value using 
methods approved by the Board of Trustees. 

   Balanced Portfolio: 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 Portfolio is determined as of the latter 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. 

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

   o  The Value, Fixed Income, High Yield, Limited Duration and Balanced 
      Portfolios normally distribute substantially all of their net 
      investment income to shareholders in the form of quarterly dividends. 

   o  The Mid Cap Growth Portfolio normally distributes substantially all of 
      its net investment income in the form of annual dividends. 

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

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

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

   In all portfolios 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. 

   Federal Taxes: The following summary of Federal income tax consequences is 
based on current tax laws and regulations, which may be changed by 
legislative, judicial or administrative action. No attempt has been made to 

- --------------------------------------------------------------------------------
MAS Funds - 40         Terms in bold type are defined in the Prospectus Glossary

<PAGE>

present a detailed explanation of the federal income tax treatment of the 
portfolio or its shareholders. In addition, state and local tax consequences 
of an investment in the portfolio may differ from the Federal income tax 
consequences described below. Accordingly, shareholders are urged to consult 
their tax advisers regarding specific questions as to federal, state and 
local taxes. 

   Each portfolio of the Fund intends to qualify for taxation as a regulated 
investment company under the Internal Revenue Code of 1986 (the "Code") so 
that each portfolio will not be subject to Federal income tax to the extent 
it distributes net investment company taxable income and net capital gains 
(the excess of net long-term capital gain over net short-term capital loss) 
to shareholders. Each Portfolio is treated as a separate entity for Federal 
income tax purposes and is not combined with any of the Funds' other 
portfolios. Dividends, either in cash or reinvested in shares, paid by a 
portfolio from net investment income will be taxable to shareholders as 
ordinary income. In the case of the Value, Mid Cap Growth, and Balanced 
Portfolios, such dividends paid to corporate shareholders will generally 
qualify in part for the dividends received deduction for corporations to the 
extent attributable to dividends received by such portfolios from domestic 
corporations. The Fund will send each shareholder of such portfolios a 
statement each year indicating the amount of the dividend income which 
qualifies for such treatment. 

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

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

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

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

   Foreign Income Taxes: Investment income received by the portfolios from 
sources within foreign countries may be subject to foreign income taxes 
withheld at the source. The U.S. has entered into Tax Treaties with many 
foreign countries which entitle these portfolios to a reduced rate of tax or 
exemption from tax on such income. It is impossible to determine the 
effective rate of foreign tax in advance since the amount of the portfolios' 
assets to be invested within various countries is not known. The portfolios 
intend to operate so as to qualify for treaty reduced rates of tax where 
applicable. No portfolio will be able to elect to treat shareholders as 
having paid their proportionate share of such taxes for foreign tax credit 
purposes.

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

   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 the Morgan Stanley 
Group, Inc., and is located at One Tower Bridge, West Conshohocken, PA 19428. 
Miller Anderson & Sherrerd, LLP is an Equal Opportunity/Affirmative Action 
Employer. The Adviser provides investment services to employee benefit plans, 
endowment funds, foundations and other institutional investors and as of the 
date of this prospectus had in excess of $40.9 billion in assets under 
management. 

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

                                                      Rate 
                                                     ------- 
              Mid Cap Growth Portfolio                .500% 
              Value Portfolio                         .500 
              Fixed Income Portfolio                  .375 
              High Yield Portfolio                    .375 
              Limited Duration Portfolio              .300 
              Balanced Portfolio                      .450 


Until further notice, the Adviser has voluntarily agreed to waive advisory 
fees and/or reimburse certain other expenses to the extent necessary to keep 
Total Operating Expenses actually deducted from portfolio assets for the 
Adviser Class of Value and Limited Duration Portfolios from exceeding 0.900% 
and 0.700%, respectively. 

For the fiscal year ended September 30, 1996, the Adviser received the 
following as compensation for its services: 

                                                      Rate 
                                                     -------

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

sub-administration agreement with MAS as Administrator. 

DISTRIBUTION PLAN: Adviser Class Shares are sold without a sales charge, but 
are subject to a Rule 12b-1 fee. The Fund, on behalf of the applicable 
portfolio, will make monthly payments to the Fund's distributor under the 
Distribution Plan approved by the Board of Trustees at an annual rate of up 
to .25% of each portfolio's average daily net assets attributable to Adviser 
Class Shares. The Fund's distributor will use the Rule 12b-1 fee it receives 
for (i) compensation for its services in connection with distribution 
assistance or provision of shareholder or account maintenance services, or 
(ii) payments to financial intermediaries, plan fiduciaries, and investment 
professionals, including the Adviser, for providing distribution support 
services, and/or account maintenance services to shareholders (including, 
where applicable, any underlying beneficial owners) of Adviser Class Shares. 

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

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

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

Some securities considered for investment by each of the Fund's portfolios 
may also be appropriate for other clients served by the Adviser. If purchase 
or sale of securities consistent with the investment policies of a portfolio 
and one or more of these other clients served by the Adviser is considered at 
or about the same time, transactions in such securities will be allocated 
among the portfolio and clients in a manner deemed fair and reasonable by the 
Adviser. Although there is no specified formula for allocating such

- -------------------------------------------------------------------------------
                            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 persons
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.

Where applicable as described in Financial Highlights, 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 
expense that otherwise would be deducted from portfolio assets. 

* Until further notice, the Adviser has voluntarily agreed to waive its 
advisory fees and reimburse certain expenses to the extent necessary to keep 
Total Operating Expenses actually deducted from portfolio assets from 
exceeding 0.150%, 0.080% and 1.180% for the Advisory Foreign Fixed Income, 
Advisory Mortgage and Emerging Markets Portfolios, respectively. Absent these 
fee waivers by the Adviser, Total Operating Expenses would be 0.499%, 0.479% 
and 1.290% for the Advisory Foreign Fixed Income, Advisory Mortgage and 
Emerging Markets Portfolios, respectively. 

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

portfolios begin on page 6; 
SUMMARY PAGES of each portfolio's Objective, Policies and Strategies begin on

                              PROSPECTUS SUMMARY 

The Advisory Foreign Fixed Income Portfolio seeks to achieve above-average 
total return over a market cycle of three to five years, consistent with 
reasonable risk, by investing primarily in high-grade Foreign Bonds and 
Derivatives. The portfolio is available only to private advisory clients of 
Miller Anderson & Sherrerd, LLP. 

The Advisory Mortgage Portfolio seeks to achieve returns consistent with 
returns generated by the market for Mortgage Securities by investing 
primarily (at least 65% of its assets under normal circumstances) in mortgage 
securities. The portfolio's average weighted maturity will ordinarily be 
greater than seven years. The portfolio is available only to private advisory 
clients of Miller Anderson & Sherrerd, LLP. 

The Emerging Markets Portfolio seeks to achieve long-term capital growth by 
investing primarily in Common Stocks of Emerging Market Issuers. [The 
portfolio is available only to private advisory clients of Miller Anderson & 
Sherrerd LLP.] 

RISK FACTORS: Prospective investors in the Portfolios should consider the 
following factors as they apply to each Portfolio's allowable investment 
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 the borrower fail financially; 
o  Fixed-Income Securities that may be acquired by the Portfolios will be 
   affected by general changes in interest rates resulting in increases or 
   decreases in the value of the obligations held by a portfolio. The value 
   of fixed-income securities can be expected to vary inversely to changes in 
   prevailing interest rates, i.e., as interest rates decline, market value 
   tends to increase and vice versa; 
o  Each portfolio may purchase securities on a When-Issued basis. 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 may invest a portion of its assets in Derivatives 
   securities 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 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; 

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

<PAGE>

o  Investments in floating rate securities (Floaters) and inverse floating 
   rate securities (Inverse Floaters) and Mortgage-Backed Securities 
   (Mortgage Securities) including principal-only and interest-only Stripped 
   Mortgage-Backed Securities (SMBS), may be highly sensitive to interest 
   rate changes, and highly sensitive to the rate of principal payments 
   (including prepayments on underlying mortgage assets); 
o  Investments in foreign securities involves certain special considerations 
   which are not typically associated with investing in U.S. companies. See 
   Foreign Investing. A portfolio investing in foreign securities may also 
   engage in foreign currency exchange transactions; and, 
o  The Advisory Foreign Fixed Income and Emerging Markets Portfolios are 
   Non-Diversified for purposes of the Investment Company Act of 1940, as 
   amended, meaning that they may invest a greater percentage of assets in 
   the securities of one issuer than other portfolios. 

HOW TO INVEST: Shares of each portfolio are offered directly to investors 
without a sales commission at the net asset value of the portfolio next 
determined after receipt of the order. Investment is available only to 
advisory clients of MAS. 

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.

YIELD AND TOTAL RETURN 

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

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

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

The 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, and various indices, 
all as further described in the Statement of Additional Information. 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 will be provided 
without charge upon request by writing to the Fund or calling the Client 
Services Group at the telephone number shown on the front cover of this 
Prospectus. 

GENERAL INFORMATION 

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

Objectives: Each portfolio seeks to achieve its investment objective relative 
to the universe of securities in which it is authorized to invest and, 
accordingly, the total return or current income achieved by a portfolio may 
not be as great as that achieved by another portfolio that can invest in a 
broader range of securities. The Advisory Foreign Fixed Income and Advisory 
Mortgage Portfolio will seek to produce total return by actively trading 
portfolio securities. The achievement of any portfolio's objective cannot be 
assured. 

Suitability: The portfolios are designed for advisory clients of MAS who are 
investing in the Fund as part of a larger investment and who, as long-term 
investors, can accept the risks entailed in investing in the stock and bond 
markets. 

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 

- --------------------------------------------------------------------------------
MAS Funds - 6          Terms in bold type are defined in the Prospectus Glossary
<PAGE>

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 in securities that are illiquid by virtue of the 
absence of a readily available market, or because of legal or contractual 
restrictions on resale. This policy does not limit the acquisition of (i) 
restricted securities eligible for resale to qualified institutional buyers 
pursuant to Rule 144A under the Securities Act of 1933 or (ii) commercial 
paper issued pursuant to Section 4(2) under the Securities Act of 1933, that 
are determined to be liquid in accordance with guidelines established by the 
Fund's Board of Trustees. 

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

With respect to the Advisory Foreign Fixed Income and Advisory Mortgage 
Portfolios, the annual turnover rate will ordinarily exceed 100% due to 
changes in portfolio duration, yield curve strategy or commitments to forward 
delivery mortgage-backed securities. Portfolio turnover rates for the 
portfolios as of September 30, 1996 are as follows: Advisory Foreign Fixed 
Income - 170%, Advisory Mortgage - 139% and Emerging Markets - 108%. High 
rates of portfolio turnover necessarily result in correspondingly heavier 
brokerage and portfolio trading costs which are paid by a portfolio. Trading 
in Fixed-Income Securities does not generally involve the payment of 
brokerage commissions, but does involve indirect transaction costs. In 
addition to portfolio trading costs, higher rates of portfolio turnover may 
result in the realization of capital gains. To the extent net short-term 
capital gains are realized, any distributions resulting from such gains are 
considered ordinary income for federal income tax purposes. 

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

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

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

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

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

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary          MAS Funds - 7
<PAGE>

(c) a portfolio will not acquire any securities of companies within one 
industry, if, as a result of such acquisition, more than 25% of the value of 
the portfolio's total assets would be invested in securities of companies 
within such industry; provided, however, that (1) there shall be no 
limitation on the purchase of obligations issued or guaranteed by the U.S. 
Government, its agencies or instrumentalities, or instruments issued by U.S. 
banks when any such portfolio adopts a temporary defensive position; (2) with 
respect to the Emerging Markets Portfolio, utility companies will be divided 
according to their services, for example, gas, gas transmission, electric and 
telephone will each be considered a separate industry; (3) with respect to 
the Emerging Markets Portfolio, financial service companies will be 
classified according to the end users of their services, for example, 
automobile finance, bank finance and diversified finance will each be 
considered a separate industry; (4) asset-backed securities will be 
classified according to the underlying assets securing such securities; and 
(5) the Advisory Mortgage Portfolio will concentrate in Mortgage Securities. 

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

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

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

(g) a portfolio will not invest its assets in securities of any investment 
company, except as permitted by the 1940 Act or the rules, regulations, 
interpretations or orders of the SEC and its staff thereunder. 

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

                             PROSPECTUS GLOSSARY 
           CHARACTERISTICS AND RISKS OF STRATEGIES AND INVESTMENTS 

STRATEGIES 

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/or 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). 

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

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

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

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

Although a portfolio will endeavor to achieve the most favorable execution 
costs in its portfolio transactions in foreign securities, fixed commissions 
on many foreign stock exchanges are generally higher than negotiated 
commissions on U.S. exchanges. In addition, it is expected that the expenses 
for custodial arrangements of a portfolio's 

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 11
<PAGE>

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. 

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

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

The market for high yield securities is still relatively new. Because of 
this, a long-term track record for bond default rates does not exist. In 
addition, the secondary market for high yield securities is generally less 
liquid than that for investment grade corporate securities. In periods of 
reduced market liquidity, high yield bond prices may become more volatile, 
and both the high yield market and a portfolio may experience sudden and 
substantial price declines. This lower liquidity might have an effect on a 
portfolio's ability to value or dispose of such securities. Also, there 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 coupon bonds pay interest only at maturity and payment-in-kind 
bonds pay interest in the form of additional securities. Payment in the form 
of additional securities, or interest income recognized through discount 
accretion, will, however, be treated as ordinary income which will be 
distributed to shareholders even though the portfolio does not receive 
periodic cash flow from these investments. 

The table below provides a summary of ratings assigned to all U.S. and 
foreign debt holdings of the Emerging Markets Portfolio with more than 5% 
invested in High Yield securities as of September 30, 1996 (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. The portfolio's debt holdings total less 
than 100% because it also invests in Equity Securities.

Maturity and Duration Management: One of two primary components of the 
Adviser's fixed-income investment strategy is maturity and duration 
management. The maturity and duration structure of a portfolio investing in 
Fixed-Income Securities is actively managed in anticipation of cyclical 
interest rate changes. Adjustments are not made in an effort to capture 
short-term, day-to-day movements in the market, but instead are implemented 
in anticipation of longer term shifts in the levels of interest rates. 
Adjustments made to shorten portfolio maturity and duration are made to limit 
capital losses during periods when interest rates are expected to rise. 
Conversely, adjustments made to lengthen maturity are intended to produce 
capital appreciation in periods when interest rates are expected to fall. The 
foundation for maturity and duration strategy lies in analysis of the U.S. 
and global economies, focusing on levels of real interest rates, monetary and 
fiscal policy actions, and cyclical indicators. See Value Investing for a 
description of the second primary component of MAS'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: The Advisory Mortgage Portfolio will be primarily (at 
least 65% of the time under normal circumstances) invested in 
mortgage-related securities. These include mortgage-backed securities which 
represent interests in pools of mortgage loans made by lenders such as 
commercial banks, savings and loan associations, mortgage bankers and others. 
The pools are assembled by various organizations, including the Government 
National Mortgage Association (GNMA), Federal Home Loan Mortgage Corporation 
(FHLMC), Federal National Mortgage Association (FNMA), other government 
agencies, and private issuers. It is expected that a portfolio's primary 
emphasis will be in mortgage-backed securities issued by the various 
Government-related organizations. However, a portfolio may invest, without 
limit, in mortgage-backed securities issued by private issuers when the 
Adviser deems that the quality of the investment, the quality of the issuer, 
and market conditions warrant such investments. Securities issued by private 
issuers will be rated investment grade by Moody's or Standard & Poor's or be 
deemed by the Adviser to be of comparable investment quality. 

Non-Diversified Status: A portfolio may be classified as a non-diversified 
investment company under the Investment Company Act of 1940, as amended. 
Non-diversified portfolios may invest more than 25% of assets in securities 
of individual issuers representing greater than 5% each of a portfolio's 
total assets, whereas diversified invest

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

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

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 Depositary 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 addition the 
short-term nature of the loans reduces the impact of any change in prepayment 
level. Due to amortization, the average life for these securities is also the 
conventional proxy for maturity. 

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

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

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

- --------------------------------------------------------------------------------
MAS Funds - 14         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

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

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

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 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); 

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

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

(5) 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, Federal 
National Mortgage Association, Federal Financing Bank, the Tennessee Valley 
Authority, and others; and 

(6) Repurchase agreements collateralized by securities listed above. 

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

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

Like bonds in general, mortgage-backed securities will generally decline in 
price when interests 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. 

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 bond 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. 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 that are not listed in 
the applicable Allowable Investments for the portfolio. Any applicable 
limitations are described under each investment definition. Each of the 
Portfolios covered by this Prospectus may enter into over-the-counter 
Derivatives transactions (Swaps, Caps, Floors, Puts, etc., but excluding 
CMOs, Forwards, Futures and Options, and SMBS) with counterparties approved 
by MAS in accordance with guidelines established by the Board of Trustees. 
These guidelines provide for a minimum credit rating for each counterparty 
and various credit enhancement techniques (for example, collateralization of 
amounts due from counterparties) to limit exposure to counterparties with 
ratings below AA. Derivatives include, but are not limited to CMOs, Forwards, 
Futures and Options, SMBS, Structured Investments, Structured Notes and 
Swaps. See each individual portfolio's listing of Investments to determine 
which of these the Portfolio may hold. 

Eastern European Issuers: The economies of Eastern European countries are 
currently suffering both from the stagnation resulting from centralized 
economic planning and control and the higher prices and unemployment 
associated with the transition to market economies. 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. In the event of the return to power of the Communist Party, there 
can be no assurance that the portfolio's investments in Eastern Europe would 
not be expropriated, nationalized or otherwise confiscated. 

Emerging Markets Issuers: An emerging market security is one issued by a 
company that has one or more of the following characteristics: (i) its 
principal securities trading market is in an emerging market; (ii) alone or 
on a consolidated basis it derives 50% or more of its annual revenue from 
either goods produced, sales made or services performed in emerging markets, 
or (iii) it is organized under the laws of, and has a principal office in, an 
emerg-

<PAGE>

ing market country. The Adviser will base determinations as to eligibility on 
publicly available information and inquiries made to the companies. Investing 
in emerging markets may entail purchasing securities issued by or on behalf 
of entities that are insolvent, bankrupt, in default or otherwise engaged in 
an attempt to reorganize or reschedule their obligations, and in entities 
that have little or no proven credit rating or credit history. In any such 
case, the issuer's poor or deteriorating financial condition may increase the 
likelihood that the investing fund will experience losses or diminution in 
available gains due to bankruptcy, insolvency or fraud. 

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

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

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

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

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

Foreign Equities: are Common Stock, Preferred Stock, Rights and Warrants of 
foreign issuers denominated in foreign currency and traded primarily in 
non-U.S. markets. 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 

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 17
<PAGE>

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 those transactions create residual foreign 
currency exposure. When a portfolio enters into a forward contract for 
purposes of creating a position hedge, transaction hedge, cross hedge, or a 
synthetic security, it will generally be required to hold liquid securities 
or cash in a segregated account with a daily value at least equal to its 
obligation under the forward contract. 

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

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

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

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

- --------------------------------------------------------------------------------
MAS Funds - 18         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

    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." C - The rating C is reserved for 
    income bonds on which "no interest is being paid." D - Debt rated D 
    is in "default", and "payment of interest and/or repayment of 
    principal is in arrears." 

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

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

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

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

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

Investment Funds: Some emerging market countries have laws and regulations 
that currently preclude direct foreign investment in the securities of their 
companies. However, indirect foreign investment in the securities of 
companies listed and traded on the stock exchanges in these countries is 
permitted by certain emerging market coun-

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 19
<PAGE>

tries through investment funds. Portfolios that may invest in these 
investment funds are subject to applicable law as discussed under Investment 
Restrictions and will invest in such investment funds only where appropriate 
given that the portfolio's shareholders will bear indirectly the layer of 
expenses of the underlying investment funds in addition to their 
proportionate share of the expenses of the portfolio. Under certain 
circumstances, an investment in an investment fund will be subject to the 
additional limitations that apply to investments in Investment Companies. 

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

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

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

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

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

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

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

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

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

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 per-

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 21
<PAGE>

mit the portfolio to keep all its assets at work while retaining overnight 
flexibility in pursuit of investments of a longer term nature. The Adviser 
will continually monitor the value of the underlying collateral to ensure 
that its value, including accrued interest, always equals or exceeds the 
repurchase price. 

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

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

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

SMBS are usually structured with two classes that receive different 
proportions of the interest and principal distributions on a pool of mortgage 
assets. One type of SMBS will have one class receiving some of the interest 
and most of the principal from the mortgage assets, while the other class 
will receive most of the interest and the remainder of the principal. In some 
cases, one class will receive all of the interest (the 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 Investment Company Act of 1940. A 
trust unit pays a return based on the total return of securities and other 
investments held by the trust and the trust may enter into one or more Swaps 
to achieve its objective. For example, a trust may purchase a basket of 
securities and agree to exchange the return generated by those securities for 
the return generated by another basket or index of securities. A portfolio 
will purchase Structured Investments in trusts that engage in such Swaps only 
where the counterparties are approved by MAS in accordance with credit-risk 
guidelines established by the Board of Trustees. 

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

Swaps--Swap Contracts: are Derivatives in the form of a contract or other 
similar instrument which is an agreement to exchange the return generated by 
one instrument for the return generated by another instrument. The pay- 

- --------------------------------------------------------------------------------
MAS Funds - 22         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

ment 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 
notional amount. 

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

Possible Risks: Interest rate and total rate of return swaps do not involve 
the delivery of securities, other underlying assets, or principal. 
Accordingly, the risk of loss with respect to interest rate and total rate of 
return swaps is limited to the net amount of interest payments that a 
portfolio is contractually obligated to make. If the other party to an 
interest rate or total rate of return swap defaults, a portfolio's risk of 
loss consists of the net amount of interest payments that a portfolio is 
contractually entitled to receive. In contrast, currency swaps 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. 

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. 

Zero Coupons--Zero Coupon Obligations: are Fixed-Income Securities that do 
not make regular interest payments. Instead, zero coupon obligations are sold 
at substantial discounts from their face value. The difference between a zero 
coupon obligation's issue or purchase price and its face value represents the 
imputed interest an investor will earn if the obligation is held until 
maturity. Zero coupon obligations may offer investors the opportu-

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 23
<PAGE>

nity 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 INFORMATION 

PURCHASE OF SHARES 

The Advisory Foreign Fixed Income, Advisory Mortgage and Emerging Markets 
Portfolios are available only to private advisory clients of Miller Anderson 
& Sherrerd, LLP, Adviser to MAS Funds. 

Shares of each portfolio may be purchased at the net asset value per share 
next determined after receipt of the purchase order. The portfolios determine 
net asset value as described under General Information-Valuation of Shares 
each day that the portfolios are open. See Other Information-Closed Holidays. 

Other Purchase Information: The Fund reserves the right, in its sole 
discretion, to suspend the offering of shares of any of its portfolios or to 
reject any purchase orders when, in the judgment of management, such 
suspension or rejection is in the best interest of the Fund. 

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. 

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. 

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

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

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

VALUATION OF SHARES 

Advisory Foreign Fixed Income and Advisory Mortgage 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 

- --------------------------------------------------------------------------------
MAS Funds - 24         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

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

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

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

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

DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES 

Dividends and Capital Gains Distributions: The Advisory Foreign Fixed Income 
Portfolio and the Advisory Mortgage Portfolio will normally distribute 
substantially all of their net investment income to shareholders in the form 
of quarterly and monthly dividends, respectively. The Emerging Markets 
Portfolio normally distributes substantially all of its net investment income 
in the form of annual dividends. 

Certain mortgage-backed 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. 

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

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 25
<PAGE>

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

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

Federal Taxes: The following summary of Federal income tax consequences 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 federal income tax treatment of the 
portfolio or its shareholders. In addition, state and local tax consequences 
of an investment in the portfolio may differ from the Federal income tax 
consequences described below. Accordingly, shareholders are urged to consult 
their tax advisers regarding specific questions as to federal, state and 
local taxes. 

Each portfolio intends to qualify for taxation as a regulated investment 
company under the Internal Revenue Code of 1986 (the "Code") so that each 
portfolio will not be subject to Federal income tax to the extent it 
distributes net investment company taxable income and net capital gains (the 
excess of net long-term capital gain over net short-term capital loss) to 
shareholders. Each Portfolio is treated as a separate entity for Federal 
income tax purposes and is not combined with any of the Funds' other 
portfolios. Dividends, either in cash or reinvested in shares, paid by a 
portfolio from net investment income will be taxable to shareholders as 
ordinary income. The Fund will send each shareholder a statement each year 
indicating the amount of the dividend income which qualifies for such 
treatment and will generally not qualify for the dividends received deduction 
for corporations. 

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

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

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

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

Foreign Income Taxes: Investment income received by the portfolios from 
sources within foreign countries may be subject to foreign income taxes 
withheld at the source. The U.S. has entered into Tax Treaties with many 
foreign countries which entitle these portfolios to a reduced rate of tax or 
exemption from tax on such income. It is impossible to determine the 
effective rate of foreign tax in advance since the amount of the portfolios' 
assets to be invested within various countries is not known. The portfolios 
intend to operate so as to qualify for treaty reduced rates of tax where 
applicable. 


- --------------------------------------------------------------------------------
MAS Funds - 26         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

The Advisory Foreign Fixed Income and the Emerging Markets Portfolios may 
file an election with the Internal Revenue Service to pass through to the 
portfolio's shareholders the amount of foreign income taxes paid by the 
portfolio, but may do so only if more than 50% of the value of the total 
assets of the portfolio at the end of the fiscal year is represented by 
foreign securities. The portfolios will make such an election only if they 
deem it to be in the best interests of their shareholders. The Federal income 
tax status of the portfolio will not be affected by the election. 

If this election is made, shareholders of the portfolio will be required to: 
(i) include in gross income, even though not actually received, their 
respective pro rata share of foreign taxes paid by the portfolio; (ii) treat 
their pro rata share of foreign taxes as paid by them; and (iii) either 
deduct their pro rata share of foreign taxes in computing their taxable 
income or use it within the limitations set forth in the Internal Revenue 
Code as a foreign tax credit against U.S. income taxes (but not both). 

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

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

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 
below, certain companies provide essential management, administrative and 
shareholder services to the Trust. 

INVESTMENT ADVISER 

The Investment Adviser to the Fund, Miller Anderson & Sherrerd, LLP is a 
Pennsylvania limited partnership founded in 1969, wholly owned by indirect 
subsidiaries of Morgan Stanley Group, Inc., and is located at One Tower 
Bridge, West Conshohocken, PA 19428. Miller Anderson & Sherrerd, LLP is an 
Equal Opportunity/Affirmative Action Employer. The Adviser provides 
investment services to employee benefit plans, endowment funds, foundations 
and other institutional investors and as of the date of this prospectus had 
in excess of $40.9 billion in assets under management. 

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

                                                        Rate 
                                                     --------- 
              Advisory Foreign Fixed Income           0.375%* 
              Advisory Mortgage                       0.375* 
              Emerging Markets                        0.750*+ 

* Until further notice, the Adviser has voluntarily agreed to waive its 
  advisory fees for the Advisory Foreign Fixed Income and Advisory Mortgage 
  Portfolios. In addition, the Adviser has voluntarily agreed to reimburse 
  certain expenses to the extent necessary to keep Total Operating Expenses 
  actually deducted from each Portfolio's assets

<PAGE>

  for the Advisory Foreign Fixed Income, Advisory Mortgage and Emerging 
  Markets Portfolios from exceeding 0.15%, 0.08% and 1.18%, respectively. 
  Absent these fee waivers and reimbursements by the Adviser, Total Operating 
  Expenses would be 0.50%, 0.48% and 1.29% for the Advisory Foreign Fixed 
  Income, Advisory Mortgage and Emerging Markets Portfolios, respectively. 

+ Advisory fees in excess of 0.750% of average net assets are considered 
  higher than normal for most investment companies, but are not unusual for 
  portfolios that invest primarily in small capitalization stocks or in 
  countries with emerging market economies. 

For the fiscal year ended September 30, 1996, the Adviser received no 
compensation for its services under the Investment Advisory Agreement with 
respect to the Advisory Foreign Fixed Income and Advisory Mortgage 
Portfolios, and received compensation at the rate of 0.636% of average net 
assets with respect to the Emerging Markets Portfolio.

Tremont Street, Boston MA 02108-3913, serves as Transfer Agent to the Fund 
pursuant to an agreement also dated as of November 8, 1993, and provides fund 
accounting and other services pursuant to a sub-administration agreement with 
MAS as Administrator. 

GENERAL DISTRIBUTION AGENT 

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

PORTFOLIO TRANSACTIONS 

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

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

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

                              PROSPECTUS SUMMARY 

The Small Cap Value Portfolio (not currently offered to new investors) seeks 
to achieve above-average total return over a market cycle of three to five 
years, consistent with reasonable risk, by investing primarily in a 
diversified portfolio of Common Stocks with equity capitalizations in the 
range of companies represented in the Russell 2000 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. 

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

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

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

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

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

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


HOW TO INVEST: This Prospectus is for use only by defined contribution plan 
participants who may invest according to plan specifications. For information 
on how to purchase, redeem, or exchange Institutional Class Shares, 
participants should contact their plan administrator.

##   For the years ended September 30, 1995 and 1996, the Ratio of Expenses to
     Average Net Assets for the Small Cap Value Portfolio excludes the effect of
     expense offsets. If expense offsets were included, the Ratio of Expenses to
     Average Net Assets would not significantly differ.

     required to disclose the average commission rate per share it paid for
     trades on which commissions were charged.

YIELD AND TOTAL RETURN: 

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

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

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

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

GENERAL INFORMATION: 

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

Objectives: The 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 the portfolio may 
not be as great as that achieved by another portfolio that can invest in a 
broader range of securities. The objective of the portfolio is fundamental 
and may only be changed with approval of holders of a majority of the shares 
of the portfolio. The achievement of the portfolio's objective cannot be 
assured. 

Suitability: The portfolio is designed for long-term investors who can accept 
the risks entailed in investing in the stock and bond markets, and is not 
meant to provide a vehicle for playing short-term swings in the market. The 
portfolio is designed principally for the investments of tax-exempt fiduciary 
investors who are entrusted with the 

- --------------------------------------------------------------------------------
MAS Funds - 6          Terms in bold type are defined in the Prospectus Glossary

<PAGE>
responsibility of investing assets held for the benefit of others. Since such 
investors are not subject to Federal income taxes, securities transactions 
will not be influenced by the different tax treatment of long-term capital 
gains, short-term capital gains, and dividend income under the Internal 
Revenue Code. 

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


Turnover: The Adviser manages the portfolio generally without regard to 
restrictions on portfolio turnover, except those imposed by provisions of the 
federal tax laws regarding short-term trading. In general, the portfolio will 
not trade for short-term profits, but when circumstances warrant, investments 
may be sold without regard to the length of time held. The portfolio's 
turnover rate for the fiscal year ended September 30, 1996 was 145%. High 
rates of portfolio turnover necessarily result in correspondingly heavier 
brokerage and portfolio trading costs which are paid by the portfolio. 


Cash Equivalents/Temporary Defensive Investing: Although the portfolio 
intends to remain substantially fully invested, a small percentage of the 
portfolio's assets are generally held in the form of Cash Equivalents in 
order to meet redemption requests and otherwise manage the daily affairs of 
the portfolio. In addition, the 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 the 
portfolio without limit. 

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. The portfolio will not concentrate investments in any one industry. 

Investment Limitations: The 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, the 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. 


(b) with respect to 75% of its assets, the 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. 

(c) the portfolio will not acquire any securities of companies within one 
industry, if, as a result of such acquisition, more than 25% of the value of 
the portfolio's total assets would be invested in securities of companies 
within such industry; provided, however, that (1) there shall be no 
limitation on the purchase of obligations issued or guaranteed by the U.S. 
Government, its agencies or instrumentalities; (2) utility companies will be 
divided according to their services, for example, gas, gas transmission, 
electric and telephone will each be considered a separate industry; (3) 
financial service companies will be classified according to the end users of 
their services, for example, automobile finance, bank finance and diversified 
finance will each be considered a separate industry, and (4) asset-backed 
securities will be classified according to the underlying assets securing 
such securities.

<PAGE>


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

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

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

(g) the portfolio will not invest its assets in securities of any Investment 
Company, except as permitted by the 1940 Act or the rules, regulations, 
interpretations or orders of the SEC and its staff thereunder. 

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

Small 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 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 typically be lower than 
                           for the Equity and Value Portfolios. 

Approach:                  The Adviser selects common stocks which are 
                           deemed to be undervalued at the time of 
                           purchase, based on proprietary measures of 
                           value. The Portfolio will be structured taking 
                           into account the economic sector weights of 
                           the Russell 2000 Index, with the portfolio's 
                           sector weights normally being within 5% of the 
                           sector weights for the Index. 

Policies:                  Generally at least 65% invested in Equity 
                           Securities of small-cap companies deemed to be 
                           undervalued 
                           Up to 5% invested in Foreign Equities 
                           (excluding ADRs) 
                           Derivatives may be used to pursue portfolio 
                           strategy 


Capitalization Range:      Generally matching the Russell 2000 size 
                           distribution (currently $50 million to $1 
                           billion)

                             PROSPECTUS GLOSSARY 
           CHARACTERISTICS AND RISKS OF STRATEGIES AND INVESTMENTS 

STRATEGIES 

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 


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 Depositary 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.


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).

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

The portfolio 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) The 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).

(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);

- --------------------------------------------------------------------------------
MAS Funds - 10         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

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

(5) 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, Federal
National Mortgage Association, Federal Financing Bank, the Tennessee Valley
Authority, and others, and;

(6) Repurchase agreements collateralized by securities listed above.

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.

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. 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 portfolio may enter into
over-the-counter Derivatives transactions (Swaps, Caps, Floors, Puts, etc., but
excluding CMOs, Forwards, Futures and Options, and SMBS) with counterparties
approved by MAS in accordance with guidelines established by the Board of
Trustees. These guidelines provide for a minimum credit rating for each
counterparty and various credit enhancement techniques (for example,
collateralization of amounts due from counterparties) to limit exposure to
counterparties with ratings below AA. Derivatives include, but are not limited
to, Forwards, Futures and Options, and Swaps.

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

Fixed-Income Securities: Commonly include but are not limited to U.S.
Governments, Zero Coupons, Agencies, Corporates, Convertibles, Cash Equivalents,
Repurchase Agreements, Preferred Stock, and Foreign Bonds. 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.

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,

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 11
<PAGE>

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; and (3) 
non-government foreign corporate debt securities. 

Foreign Currency: The portfolio may invest in foreign securities and thereafter
may regularly transact security purchases and sales in foreign currencies. The
portfolio 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.

The 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
portfolio 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 the portfolio has or expects to have portfolio
exposure. The portfolio 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. The
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.

The 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 the 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, the 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 the portfolio's obligation under the forward contract. On the date
of maturity, the 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 those transactions create residual foreign currency exposure. When the
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 secu-

- --------------------------------------------------------------------------------
MAS Funds - 12         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

rity, 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.

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

Possible Risks: The primary risks associated with the use of futures and options
are (i) imperfect correlation between the change in market value of the
securities held by the portfolio and the prices of futures and options relating
to the stocks, bonds or futures contracts purchased or sold by the 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 the 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 the 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.

Investment Companies: The portfolio is permitted to invest in shares of other
open-end or closed-end investment companies. The Investment Company Act of 1940,
as amended, generally prohibits the portfolio 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 portfolio from acquiring in the aggregate more than 10% of
the outstanding voting shares of any registered closed-end investment company.

To the extent the 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 portfolio may
not purchase shares of any affiliated investment company except as permitted by
SEC Rule or Order.

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

Pursuant to an order issued by the Securities and Exchange Commission, the
portfolio may pool its daily uninvested cash balances with those of other
portfolios of the Fund 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 portfolio will incur lower transaction costs and potentially obtain
higher rates of interest on such repurchase agreements. The portfolio's
participation in the income from jointly purchased repurchase agreements will be
based on the 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.

<PAGE>

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, the 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
portfolio may enter will generally involve an agreement to pay interest streams
in one currency based on a specified index in exchange for receiving interest
streams denominated in another currency. Such swaps may involve initial and
final exchanges that correspond to the agreed upon national amount.

The 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. The portfolio's obligations
under a swap agreement will be accrued daily (offset against any amounts owing
to the portfolio) and any accrued but unpaid net amounts owed to a swap
counterparty will be covered by the maintenance of a segregated account
consisting of cash or liquid securities. The portfolio will not enter into any
swap agreement unless the counterparty meets the rating requirements set forth
in guidelines established by the Fund's Board of Trustees.

Possible Risks: Interest rate and total rate of return swaps do not involve the
delivery of securities, other underlying assets, or principal. Accordingly, the
risk of loss with respect to interest rate and total rate of return swaps is
limited to the net amount of interest payments that the portfolio is
contractually obligated to make. If the other party to an interest rate or total
rate of return swap defaults, the 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, the
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 portfolio would be less favorable than it would have been if this
investment technique were not used.

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 the portfolio in a when-issued transaction until the portfolio receives
payment or delivery from the other party to the transaction. Although the
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. The portfolio will
maintain with the custodian a segregated account consisting of cash or liquid
securities in an amount at least equal to these commitments.

Zero Coupons--Zero Coupon Obligations: are Fixed-Income Securities that do not
make regular interest payments. Instead, zero coupon obligations are sold at
substantial discounts from their face value. The difference between a zero
coupon obligation's issue or purchase price and its face value represents the
imputed interest an

- --------------------------------------------------------------------------------
MAS Funds - 14         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

investor will earn if the obligation is held until maturity. Zero coupon
obligations may offer investors the opportunity to earn higher yields than those
available on ordinary interest-paying obligations of similar credit quality and
maturity. However, zero coupon obligation prices may also exhibit greater price
volatility than ordinary fixed-income securities because of the manner in which
their principal and interest are returned to the investor.

GENERAL SHAREHOLDER INFORMATION 

This Prospectus is for use by defined contribution plan participants who may
invest according to plan specifications. For information on how to purchase,
redeem, or exchange Institutional Class Shares of the portfolio, participants
should contact their plan administrator.

                             VALUATION OF SHARES 

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

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

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

DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES: Dividends and Capital Gains
Distributions:

   o  The Small Cap Value Portfolio normally distributes substantially all of 
      its net investment income in the form of annual dividends. 

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

- --------------------------------------------------------------------------------
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 15
<PAGE>

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

All dividends and capital gains distributions are automatically paid in
additional shares of the portfolio unless the Plan Administrator elects
otherwise.

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).

Federal Taxes: The following summary of Federal income tax consequences 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 Federal income tax treatment of the portfolio or its
shareholders. In addition, state and local tax consequences of an investment in
the portfolio may differ from the Federal income tax consequences described
below. Accordingly, shareholders are urged to consult their tax advisers
regarding specific questions as to federal, state and local taxes.

The portfolio intends to qualify for taxation as a regulated investment company
under the Internal Revenue Code of 1986, as amended (the "Code") so that it will
not be subject to Federal income tax to the extent it distributes net investment
company taxable income and net capital gains (the excess of net long-term
capital gain over net short-term capital loss) to its shareholders. The
portfolio is treated as a separate entity for Federal income tax purposes and is
not combined with the Fund's other portfolios.

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

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

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

Foreign Income Taxes: Investment income received by the portfolio from sources
within foreign countries may be subject to foreign income taxes withheld at the
source. The U.S. has entered into Tax Treaties with many foreign countries which
entitle the portfolio to a reduced rate of tax or exemption from tax on such
income. It is impossible to determine the effective rate of foreign tax in
advance since the amount of the portfolio's assets to be invested within various
countries is not known. The portfolio intends to operate so as to qualify for
treaty reduced rates of tax where applicable. The portfolio will not be able to
elect to treat shareholders as having paid their proportionate share of such
taxes for foreign tax credit purposes.

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

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 the Morgan Stanley
Group, Inc., and is located at One Tower Bridge, West Conshohocken, PA 19428.
Miller Anderson & Sherrerd, LLP is an Equal Opportunity/Affirmative Action
Employer. The Adviser provides investment services to employee benefit plans,
endowment funds, foundations and other institutional investors and as of the
date of this prospectus had in excess of $40.9 billion in assets under
management.

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 the
portfolio pays the Adviser an advisory fee calculated by applying a quarterly
rate, based on the following annual percentage rates, to the portfolio's average
daily net assets for the quarter:

                                                                        Rate 
                                                                       ------- 
Small Cap Value Portfolio*                                              .750% 


* Advisory fees in excess of 0.750% of average net assets are considered 
  higher than normal for most investment companies, but are not unusual for 
  portfolios that invest primarily in small capitalization stocks. 


For the fiscal year ended September 30, 1996, the Adviser received the 
following as compensation for its services: 

                                                                        Rate 
                                                                        ------

PORTFOLIO MANAGEMENT 

The investment professionals of MAS who are primarily responsible for the 
day-to-day management of the portfolio are as follows: 

Gary G. Schlarbaum, Managing Director, Morgan Stanley; Director, MAS Fund 
Distribution Inc., joined MAS in 1987. He assumed responsibility for the 
Small Cap Value Portfolio in 1987. 

Bradley S. Daniels, Vice President, Morgan Stanley, joined MAS in 1985. He 
assumed responsibility for the Small Cap Value Portfolio in 1986. 

William B. Gerlach, Vice President, Morgan Stanley, joined MAS in 1991. He 
assumed responsibility for the Small Cap Value Portfolio in 1996. 

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 than the lowest available when the Adviser believes 
it is reasonable to do so in light of the value of the research, statistical, 
and pricing services provided by the broker effecting the transaction. 

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

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

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

- --------------------------------------------------------------------------------
MAS Funds - 18         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

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 
Investment Company Act of 1940, as amended, 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. 

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.

EXPENSE SUMMARY - ADVISER CLASS SHARES 

The following tables illustrate the various expenses and fees that a 
shareholder for that portfolio will incur either directly or indirectly. The 
annual expenses and fees set forth below are estimated based upon the 
portfolio attaining certain average asset levels. The Adviser may from time 
to time waive fees or reimburse expenses thereby reducing total operating 
expenses. 

                    Shareholder Transaction Expenses: 
                    Sales Load Imposed on Purchases                None 
                    Sales Load Imposed on Reinvested Dividends     None 
                    Redemption Fees                                None 
                    Exchange Fees                                  None 

                    Annual Fund Operating Expenses: 
                    (as a percentage of average net assets after fee 
                    waivers) 12b-1 Fees                            0.25%

* The Adviser has agreed to waive advisory fees and/or reimburse certain 
other expenses to the extent necessary to keep the Total Operating Expenses 
of the portfolio from exceeding 0.800%. Absent this waiver estimated Total 
Operating Expenses for the portfolio would be 0.887%

EXAMPLE 

The purpose of this table is to assist in understanding the various expenses 
that a shareholder in the 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. Long-term shareholders may 
eventually pay more than the economic equivalent of the maximum front-end 
sales charge otherwise permitted by the Rules of Fair Practice of the 
National Association of Securities Dealers, Inc.

PROSPECTUS SUMMARY 

The Municipal Portfolio: seeks to realize above-average total return over a 
market cycle of three to five years, consistent with conservation of capital 
and the realization of current income which is exempt from federal income 
tax, by investing primarily in a diversified portfolio of Municipals and 
other Fixed-Income Securities and Derivatives, including a limited percentage 
of bonds rated below investment grade. The portfolio's average weighted 
maturity will ordinarily be between five and ten years. 

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

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

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

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

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

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

- ------------------------------------------------------------------------------- 
MAS Funds - 4         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

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

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

HOW TO INVEST: Adviser Class Shares of the portfolio are available to 
Shareholders with combined investments of $500,000 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 Institutional Class Shares which differ from 
the Adviser 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 the 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. 
See Redemption of Shares and Shareholder Services.

YIELD AND TOTAL RETURN 

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

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

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

The portfolio 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 portfolios yield (computed as above) by the amount 
necessary to reflect the payment of Federal income tax 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. 

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

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

GENERAL INFORMATION 

The following information relates to the portfolio and should be read in 
conjunction with the other information about the portfolio. 

Objective: The 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 the portfolio may 
not be as great as that achieved by another portfolio that can invest in a 
broader range of securities. The portfolio will seek to produce total return 
by actively trading portfolio securities. The objective of the portfolio is 
fundamental and may only be changed with approval of holders of a majority of 
the shares of the portfolio. The achievement of the portfolio's objective 
cannot be assured. 

Suitability: The portfolio is designed for long-term investors who can accept 
the risks entailed in investing in the bond market, and are not meant to 
provide a vehicle for playing short-term swings in the market. Investments in 
the portfolio are suitable for taxable investors who would benefit from the 
portfolio's tax-exempt income. 

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

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

Cash Equivalents/Temporary Defensive Investing: Although the portfolio 
intends to remain substantially fully invested, a small percentage of the 
portfolio's assets are generally held in the form of Cash Equivalents in 
order 

- ------------------------------------------------------------------------------- 
MAS Funds - 8         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

to meet redemption requests and otherwise manage the daily affairs of the 
portfolio. In addition, the 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 the portfolio 
without limit. In addition, the Adviser may, for temporary defensive 
purposes, increase or decrease the average weighted maturity or duration of 
the portfolio without regard to the 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 the portfolio's specific investment policies 
or as detailed in the Investment Limitations, the portfolio will not 
concentrate investments in any one industry. 

Investment Limitations: The 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, the 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; 

(b) with respect to 75% of its assets, the 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; 

(c) the portfolio will not acquire any securities of companies within one 
industry, if, as a result of such acquisition, more than 25% of the value of 
the portfolio's total assets would be invested in securities of companies 
within such industry; provided, however, that (1) there shall be no 
limitation on the purchase of obligations issued or guaranteed by the U.S. 
Government, its agencies or instrumentalities; (2) utility companies will be 
divided according to their services, for example, gas, gas transmission, 
electric and telephone will each be considered a separate industry; (3) 
financial service companies will be classified according to the end users of 
their services, for example, automobile finance, bank finance and diversified 
finance will each be considered a separate industry; and (4) asset-backed 
securities will be classified according to the underlying assets securing 
such securities; 

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

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

- ------------------------------------------------------------------------------- 
Terms in bold type are defined in the Prospectus Glossary         MAS Funds - 9
<PAGE>

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

(g) the portfolio will not invest its assets in securities of any investment 
company, except as permitted by the 1940 Act, as amended, or the rules, 
regulations, interpretations or orders of the SEC and its staff thereunder. 

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

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

Approach:                  The Adviser varies portfolio structure--the

                           bonds--according 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

PROSPECTUS GLOSSARY 

CHARACTERISTICS AND RISKS OF STRATEGIES AND INVESTMENTS 

STRATEGIES 

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 the 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 the portfolio may experience sudden and 
substantial price declines. This lower liquidity might have an effect on the 
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, the portfolio may find it difficult 
to value its securities accurately. The 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 coupon bonds pay interest only at maturity and payment-in-kind 
bonds pay interest in the form of additional securities. Payment in the form 
of additional securities, or interest income recognized through discount 
accretion, will, however, be treated as ordinary income which will be 
distributed to shareholders even though the portfolio does not receive 
periodic cash flow from these investments.

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

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

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

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

Mortgage Investing: At times it is anticipated that a substantial portion of 
the portfolio's assets may be invested in mortgage-related securities. These 
include mortgage-backed securities, which represent interests in pools of 
mortgage loans made by lenders such as commercial banks, savings and loan 
associations, mortgage bankers and others. The pools are assembled by various 
organizations, including the Government National Mortgage Association (GNMA), 
Federal Home Loan Mortgage Corporation (FHLMC), Federal National Mortgage 
Association 

- ------------------------------------------------------------------------------- 
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 13
<PAGE>

(FNMA), other government agencies, and private issuers. It is expected that 
the portfolio's primary emphasis will be on mortgage-backed securities issued 
by the various Government-related organizations. However, the portfolio may 
invest, without limit, in mortgage-backed securities issued by private 
issuers when the Adviser deems that the quality of the investment, the 
quality of the issuer, and market conditions warrant such investments. 
Securities issued by private issuers will be rated investment grade by 
Moody's or Standard & Poor's or be deemed by the Adviser to be of comparable 
investment quality. 

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

MAS Municipals Management emphasizes a diversified portfolio of high grade 
municipal debt securities. Under normal circumstances, the 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, the 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"). 


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


INVESTMENTS 

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

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 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 

- ------------------------------------------------------------------------------- 
MAS Funds - 14         Terms in bold type are defined in the Prospectus Glossary
<PAGE>

average life. Faster prepayment will shorten the average life and slower 
prepayments will lengthen it. However, it is possible to determine what the 
range of that movement could be and to calculate the effect that it will have 
on the price of the security. In selecting these securities, the Adviser will 
look for those securities that offer a higher yield to compensate for any 
variation in average maturity. 

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

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

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

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

The portfolio 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) The 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);

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

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

(5) 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, Federal 
National Mortgage Association, Federal Financing Bank, the Tennessee Valley 
Authority, and others; and 

(6) Repurchase agreements collateralized by securities listed above. 

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

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

Like bonds in general, mortgage-backed securities will generally decline in 
price when interests 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. 

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. The portfolio will buy 
Corporates subject to its quality constraints. If a security held by the 
portfolio is down-graded, the portfolio may retain the security if the 
Adviser deems retention of the security to be in the best interests of the 
portfolio. 

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

Eastern European Issuers: The economies of Eastern European countries are 
currently suffering both from the stagnation resulting from centralized 
economic planning and control and the higher prices and unemployment 
associated with the transition to market economics. Unstable economic and 
political conditions may adversely affect security values. Upon the accession 
to power of Communist regimes 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. In the event of the return to power of the Communist Party, there 
can be no assurance that the portfolio's investments in Eastern Europe would 
not be expropriated, nationalized or otherwise confiscated. 

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

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 the portfolio's listing of Allowable Investments to 
determine which securities a portfolio may hold. 

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

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

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

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. 

The 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 portfolio 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 the portfolio has or 
expects to have portfolio exposure. The portfolio 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. The 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. 

- ------------------------------------------------------------------------------- 
MAS Funds - 18        Terms in bold type are defined in the Prospectus Glossary
<PAGE>

The 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, the 
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, the 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 the portfolio's obligation under the forward contract. 
On the date of maturity, the 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 those transactions create 
residual foreign currency exposure. When the 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. 

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

Possible Risks: The primary risks associated with the use of futures and 
options are (i) imperfect correlation between the change in market value of 
the securities held by the 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 the 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 the portfolio may be forced 
to forego participation in the appreciation of the value of underlying 
securities, futures contracts or currency due to the writing of a call 
option. 

High Yield: High yield securities are generally considered to be corporate 
bonds, preferred stocks, and convertible securities rated Ba through C by 
Moody's or BB through D by Standard & Poor's, and unrated securities con- 

- ------------------------------------------------------------------------------- 
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 19
<PAGE>

sidered 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." C - The rating 
C is reserved for income bonds on which "no interest is being paid." D - Debt 
rated D is in "default", and "payment of interest and/or repayment of 
principal is in arrears." 

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

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

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

Investment Companies: The portfolio is permitted to invest in shares of other 
open-end or closed-end investment companies. The Investment Company Act of 
1940, as amended, generally prohibits the portfolio 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 portfolio from acquiring in the 
aggregate more than 10% of the outstanding voting shares of any registered 
closed-end investment company. 

To the extent the 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 portfolio may 
not purchase shares of any affiliated investment company except as permitted 
by SEC Rule or Order. 

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

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. The portfolio may invest in 
securities issued or guaranteed by the Government National Mortgage 
Association (GNMA), Federal Home Loan Mortgage Corporation (FHLMC), Federal 
National Mortgage Association (FNMA), private issuers and other government 
agencies. There can be no assurance that the private insurers can meet their 
obligations under the policies. Mortgage-backed securities issued by 
non-agency issuers, whether or not such securities are subject to guarantees, 
may entail greater risk. If there is no guarantee provided by the issuer, 
mortgage-backed securities purchased by the portfolio will be those which at 
time of purchase are rated investment grade by one or more NRSRO, or, if 
unrated, are deemed by the Adviser to be of investment grade quality. 

There are two methods of trading mortgage-backed securities. A specified pool 
transaction is a trade in which the pool number of the security to be 
delivered on the settlement date is known at the time the trade is made. This 
is 

- ------------------------------------------------------------------------------- 
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 21
<PAGE>

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

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

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

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

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

Municipal notes are issued to meet the short-term funding requirements of 
local, regional and state governments. Municipal notes include bond 
anticipation notes, revenue anticipation notes and tax and revenue 
anticipation notes. 

- ------------------------------------------------------------------------------- 
MAS Funds - 22        Terms in bold type are defined in the Prospectus Glossary
<PAGE>

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 portfolio 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. 

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

Pursuant to an order issued by the Securities and Exchange Commission, the 
portfolio may pool its daily uninvested cash balances with those of other 
Portfolios of the Fund 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 portfolio will incur lower transaction costs and 
potentially obtain higher rates of interest on such repurchase agreements. 
The portfolio's participation in the income from jointly purchased repurchase 
agreements will be based on its percentage share in the total purchase 
agreement. 

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 

- ------------------------------------------------------------------------------- 
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 23
<PAGE>

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 the portfolio's yield to 
maturity. If the underlying mortgage assets experience greater than 
anticipated prepayments of principal, the 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 the portfolio's limitations on 
investment in illiquid securities. 

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 the 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, 
the 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 portfolio 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 
notional amount. 

The 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 the portfolio receiving or paying, as 
the case may be, only the net amount of the two returns. The portfolio's 
obligations under a swap agreement will be accrued daily (offset against any 
amounts owing to the portfolio) and any accrued but unpaid net amounts owed 
to a swap counterparty will be covered by the maintenance of a segregated 
account consisting of cash or liquid securities. The portfolio will not enter 
into any swap agreement unless the counterparty meets the rating requirements 
set forth in guidelines established by the Fund's Board of Trustees. 

Possible Risks: Interest rate and total rate of return swaps do not involve 
the delivery of securities, other underlying assets, or principal. 
Accordingly, the risk of loss with respect to interest rate and total rate of 
return swaps is 

- ------------------------------------------------------------------------------- 
MAS Funds - 24        Terms in bold type are defined in the Prospectus Glossary
<PAGE>

limited to the net amount of interest payments that the portfolio is 
contractually obligated to make. If the other party to an interest rate or 
total rate of return swap defaults, the portfolio's risk of loss consists of 
the net amount of interest payments that the 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, the 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 portfolio 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. 

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 the portfolio in a when-issued transaction until the 
portfolio receives payment or delivery from the other party to the 
transaction. Although the 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. The portfolio will maintain with the custodian a 
segregated account consisting of cash or liquid securities in an amount at 
least equal to these commitments. 

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

GENERAL SHAREHOLDER INFORMATION 

PURCHASE OF SHARES 

Adviser Class Shares are available to Shareholders with combined investments 
of $500,000 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. 

Adviser Class Shares of the portfolio may be purchased at the net asset value 
per share next determined after receipt of the purchase order. The portfolio 
determines net asset value as described under Other Information-Valuation of 
Shares each day that the portfolio is 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 the MAS Funds, c/o Miller 
Anderson & Sherrerd, LLP, One Tower Bridge, West Conshohocken, Pennsylvania 
19428-0868 together with a check ($500,000 minimum) payable to MAS Funds. 

The Municipal Portfolio 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. Please note that purchases made 
by check are not permitted to be redeemed until payment of the purchase has 
been collected, which may take up to eight business days after purchase. 
Shareholders can avoid this delay by purchasing shares by wire. 

Initial Purchase by Wire: Subject to acceptance by the Fund, Adviser Class 
Shares of the 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 purchases, notification must 
be given to MAS Funds' Client Services Group at 1-800-354-8185 prior to the 
determination of net asset value. Adviser 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:

Additional Investments: Additional investments of Adviser Class Shares at net 
asset value may be made at any time (minimum investment $1,000) by mailing a 
check (payable to MAS Funds) to MAS Funds' Client Services Group at the 
address noted under Initial Investments by Mail or by wiring Federal Funds to 
the Custodian Bank as outlined above. Shares will be purchased at the net 
asset value per share next determined after receipt of the purchase order. 
Notification must be given to MAS Fund's Client Services Group at 
1-800-354-8185 prior to the determination of net asset value. 

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

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

Adviser Class Shares of the portfolio 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 portfolio through a Shareholder Organization may be 
charged a transaction-based fee or other fee for the services of such 
organization. The 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 may pay 
compensation to or receive compensation from Shareholder Organizations for 
the sale of Adviser Class shares. 

REDEMPTION OF SHARES 

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

By Mail: The portfolio will redeem Adviser Class Shares at the net asset 
value next determined after the request is received in good order. Requests 
should be addressed to MAS Funds, c/o 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; 

- ------------------------------------------------------------------------------- 
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 27
<PAGE>

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

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

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

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

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

By Facsimile: Written requests in good order (see above) for redemptions, 
exchanges, and transfers may be forwarded to the Fund via facsimile. All 
requests sent to the Fund via facsimile must be followed by a telephone call 
to MAS Funds' Client Services Group to ensure that the instructions have been 
properly received by the Fund. The original request must be promptly mailed 
to MAS Funds, c/o 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 NYSE, the Custodian, or the Fund is closed (see Other 
Information-Closed Holidays) or under any emergency circumstances as 
determined by the Securities and Exchange Commission. 

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 the 
portfolio in lieu of cash in conformity with applicable rules of the 
Securities and Exchange Commission. Investors may incur brokerage charges on 
the sale of portfolio securities received in such payments of redemptions.

SHAREHOLDER SERVICES 

Exchange Privilege: The portfolio's Adviser Class Shares may be exchanged for 
shares of the Fund's other portfolios offering Adviser 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 
registered for sale in a shareholder's state of residence. There are no 
exchange fees. Exchange requests should be sent to MAS Funds, c/o 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 

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

However, bonds and other Fixed-Income Securities may be valued on the basis 
of prices provided by a pricing service when such prices are believed to 
reflect the fair market value of such securities. The prices provided by a 

- ------------------------------------------------------------------------------- 
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 29
<PAGE>

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

DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES: 

The Municipal Portfolio normally distributes substantially all of its net 
investment income in the form of monthly dividends. 

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

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

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


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. 

Federal Taxes: The following summary of Federal income tax consequences is 
based on current tax laws and regulations, which may be changed by 
legislative, judicial or administrative action. No attempt has been made to 

- ------------------------------------------------------------------------------- 
MAS Funds - 30        Terms in bold type are defined in the Prospectus Glossary
<PAGE>

present a detailed explanation of the federal income tax treatment of the 
portfolio or its shareholders. In addition, state and local tax consequences 
of an investment in the portfolio may differ from the Federal income tax 
consequences described below. Accordingly, shareholders are urged to consult 
their tax advisers regarding specific questions as to federal, state and 
local taxes. 

The portfolio intends to qualify for taxation as a regulated investment 
company under the Internal Revenue Code of 1986 (the "Code") so that it will 
not be subject to Federal income tax to the extent it distributes investment 
company taxable income and net capital gain (the excess of net long-term 
capital gain over net short-term capital loss) to shareholders. The Portfolio 
is treated as a separate entity for Federal income tax purposes and is not 
combined with any of the Funds' other portfolios. 

The portfolio intends to invest a sufficient portion of its assets in 
municipal bonds and notes so that it will qualify to pay exempt-interest 
dividends to shareholders. Such exempt-interest dividends are excluded from a 
shareholder's gross income for Federal income tax purposes. Tax-exempt 
dividends received from the Municipal Portfolio may be subject to state and 
local taxes. However, some states allow shareholders to exclude that portion 
of a portfolio's tax-exempt income which is accountable to municipal 
securities issued within the shareholder's state of residence. To the extent, 
if any, that dividends paid to shareholders of the Municipal Portfolio are 
derived from taxable interest or long-term or short-term capital gains, such 
dividends will be subject to Federal personal income tax (whether such 
dividends are paid in cash or in additional shares) and may also be subject 
to state and local taxes. In addition, the Municipal Portfolio may invest in 
private activity municipal securities, the interest on which is subject to 
the Federal alternative minimum tax for corporations and individuals and the 
Federal environmental tax for corporations only. Exempt-interest dividends 
from such private activity securities issued after August 7, 1986, will 
generally be an item of tax preference and therefore potentially subject to 
the alternative minimum tax environmental tax. A shareholder may lose the tax 
exempt status of the accrued income of the portfolio if it redeems its shares 
before a dividend has been declared. The portfolio 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. Such persons should consult their tax advisers 
before purchasing shares. 

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

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

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

- ------------------------------------------------------------------------------- 
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 31
<PAGE>

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

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

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 the Morgan Stanley 
Group, Inc., and is located at One Tower Bridge, West Conshohocken, PA 19428. 
Miller Anderson & Sherrerd, LLP is an Equal Opportunity/Affirmative Action 
Employer. The Adviser provides investment services to employee benefit plans, 
endowment funds, foundations and other institutional investors and as of the 
date of this prospectus had in excess of $40.9 billion in assets under 
management. 

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 objective and policies of the portfolio, manages the 
investment and reinvestment of the portfolio's assets. In this regard, it is 
the responsibility of the Adviser to make investment decisions for the 
portfolio and to place the portfolio's purchase and sales orders. As 
compensation for the services rendered by the Adviser under the Agreement, 
the portfolio pays the Adviser an advisory fee calculated by applying a 
quarterly rate, based on an annual rate of 0.375% of the portfolio's average 
daily net assets for the quarter. 

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 
Adviser Class of the portfolio from exceeding 0.80%. 


For the fiscal year ended September 30, 1996, the Adviser received 
compensation for its services at the rate of .288%.

PORTFOLIO MANAGEMENT: 

The investment professionals of MAS who are primarily responsible for the 
day-to-day management of the portfolio are as follows: 

Steven K. Kreider, Principal, Morgan Stanley, joined MAS in 1988. He assumed 
responsibility for the Municipal Portfolio in 1992. 

Kenneth B. Dunn, Managing Director, Morgan Stanley, joined MAS in 1987. He 
assumed responsibility for the Municipal Portfolio in 1994. 

Scott F. Richard, Managing Director, Morgan Stanley, joined MAS in 1992. He 
served as Vice President, Head of Fixed Income Research & Model Development 
for Goldman, Sachs & Co. From 1987 to 1991 and as Head of Mortgage Research 
in 1992. He assumed responsibility for the Municipal Portfolio in 1994. 

ADMINISTRATIVE SERVICES: MAS serves as Administrator to the Fund pursuant to 
an Administration Agreement dated as of November 18, 1993. Under its 
Administration Agreement with the Fund, MAS receives an annual fee, accrued 
daily and payable monthly, of 0.08% of the portfolio'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. 

DISTRIBUTION PLAN: Adviser Class Shares are sold without a sales charge, but 
are subject to a Rule 12b-1 fee. The Fund, on behalf of the applicable 
portfolio, will make monthly payments to the Fund's distributor under the 
Distribution Plan approved by the Board of Trustees at an annual rate of up 
to .25% of the portfolio's average daily net assets attributable to Adviser 
Class Shares. The Fund's distributor will use the Rule 12b-1 fee it receives 
for (i) compensation for its services in connection with distribution 
assistance or provision of shareholder or account maintenance services, or 
(ii) payments to financial intermediaries, plan fiduciaries, and investment 
professionals, including the Adviser, for providing distribution support 
services, and/or account maintenance services to shareholders (including, 
where applicable, any underlying beneficial owners) of Adviser Class Shares. 

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 the portfolio and directs the Adviser to 
use its best efforts to obtain the best execution with respect to all 
transactions for the portfolio. In doing so, the portfolio may pay higher 
commission rates than the lowest available when the Adviser believes it is 
reasonable to do so in light of the value of the research, statistical, and 
pricing services provided by the broker effecting the transaction. 

- ------------------------------------------------------------------------------- 
Terms in bold type are defined in the Prospectus Glossary        MAS Funds - 33
<PAGE>

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 portfolio or who act as agents in the 
purchase of shares of the portfolio for their clients. 

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

- -------------------------------------------------------------------------------
                            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 persons
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.

                                BUSINESS HISTORY

MAS Funds (formerly MAS Pooled Trust Fund) is an open end management investment
company established under Pennsylvania law as a Pennsylvania business trust
under an Amended and Restated Agreement and Declaration of Trust dated November
18, 1993. The Fund was originally established as The MAS Pooled Trust Fund, a
Pennsylvania business trust, in February, 1984.

                           STRATEGIES AND INVESTMENTS

The following information supplement the characteristics and risks of strategies
and investments set forth in the Fund's Prospectuses:

                              REPURCHASE AGREEMENTS

Each of the Fund's Portfolios may invest in repurchase agreements collateralized
by U.S. Government securities, certificates of deposit and certain bankers'
acceptances. 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. In these
transactions, the securities purchased by a Portfolio have a total value in
excess of the value of the repurchase agreement and are held by the Portfolio's
custodian bank until repurchased. Such agreements permit a Portfolio to keep all
its assets at work while retaining "overnight" flexibility in pursuit of
investments of a longer-term nature. The Adviser and the Fund's Administrator
will continually monitor the value of the underlying securities to ensure that
their value always equals or exceeds the repurchase price.

The use of repurchase agreements involves certain risks. For example, if the
seller of the agreements defaults on its obligation to repurchase the underlying
securities at a time when the value of these securities has declined, a
Portfolio may incur a loss upon disposition of them. If the seller of the
agreement becomes insolvent and subject to liquidation or reorganization under
the Bankruptcy Code or other laws, a bankruptcy court may determine that the
underlying securities are collateral not within the control of a Portfolio and
therefore subject to sale by the trustee in bankruptcy. Finally, it is possible
that a Portfolio may not be able to substantiate its interest in the underlying
securities. While the Fund's management acknowledges these risks, it is expected
that they can be controlled through stringent security selection criteria and
careful monitoring procedures.

                               SECURITIES LENDING

Each Portfolio may lend its investment securities to qualified institutional
investors who need to borrow securities in order to complete certain
transactions, such as covering short sales, avoiding failures to deliver
securities or completing arbitrage operations. By lending its investment
securities, a Portfolio attempts to increase its income through the receipt of
interest on the loan. Any gain or loss in the market price of the securities
loaned that might occur during the term of the loan would be for the account of
the Portfolio. Each Portfolio may lend its investment securities to qualified
brokers, dealers, domestic and foreign banks or other financial institutions, so
long as the terms, the structure and the aggregate amount of such loans are not
inconsistent with the Investment Company Act of 1940, as amended, or the Rules
and Regulations or interpretations of the Securities and Exchange Commission
(the "Commission") thereunder, which currently require that (a) the borrower
pledge and maintain with the Portfolio collateral consisting of cash, an
irrevocable letter of credit issued by a domestic U.S. bank, or securities
issued or guaranteed by the United States Government having a value at all times
not less than 100% of the value of the securities loaned, (b) the borrower add
to such collateral whenever the price of the securities loaned rises (i.e., the
borrower "marks to the market" on a daily basis), (c) the loan be made subject
to termination by the Portfolio at any time, and (d) the Portfolio receive
reasonable interest on the loan (which may include the Portfolio investing any
cash collateral in interest bearing short-term investments), any distribution on
the loaned securities

                                       3
<PAGE>

and any increase in their market value. All relevant facts and circumstances,
including the creditworthiness of the broker, dealer or institution, will be
considered in making decisions with respect to the lending of securities,
subject to review by the Trustees.

At the present time, the Staff of the Commission does not object if an
investment company pays reasonable negotiated fees in connection with loaned
securities, so long as such fees are set forth in a written contract and
approved by the investment company's Trustees. In addition, voting rights may
pass with the loaned securities, but if a material event were to occur affecting
an investment on loan, the loan must be called and the securities voted.

                               FOREIGN INVESTMENTS

Investors should recognize that investing in foreign securities involves certain
special considerations which are not typically associated with investing in
domestic securities. Since the securities of foreign issuers are frequently
denominated in foreign currencies, and since the Portfolios may temporarily hold
uninvested reserves in bank deposits in foreign currencies, the Portfolios will
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. The investment policies of the Portfolios (except
for the Domestic Fixed Income, Limited Duration, Mortgage-Backed Securities,
Advisory Mortgage and Cash Reserves Portfolios) permit them to enter into
forward foreign currency exchange contracts in order to hedge their respective
holdings and commitments against changes in the level of future currency rates.
Such contracts involve an obligation to purchase or sell a specific currency at
a future date at a price set at the time of the contract.

As non-U.S. companies are not generally subject to uniform accounting, auditing
and financial reporting standards and practices comparable to those applicable
to domestic issuers, there may be less publicly available information about
certain foreign securities than about domestic securities. Securities of some
foreign issuers are generally less liquid and more volatile than securities of
comparable domestic companies. There is generally less government supervision
and regulation of stock exchanges, brokers and listed issuers than in the U.S.
In addition, 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.

Although the Portfolios will endeavor to achieve most favorable execution costs
in its portfolio transactions, 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 custodian arrangements of the Portfolio's
foreign securities will be somewhat greater than the expenses for the custodian
arrangements for handling the 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 are recoverable, the
non-recovered portion of foreign withholding taxes will reduce the income
received from investments in such countries. However, these foreign withholding
taxes are not expected to have a significant impact on those Portfolios for
which the investment objective is to seek long-term capital appreciation and any
income should be considered incidental.

The International Equity, Emerging Markets, International Fixed Income, Advisory
Foreign Fixed Income, Global Fixed Income, Multi-Asset-Class, High Yield,
Municipal, PA Municipal, Balanced Plus and Balanced Portfolios may invest in the
securities of issuers in Eastern European and other developing markets. The
economies of these 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 economies. Unstable
economic and political conditions may adversely affect security values. Upon the
accession to power of Communist regimes approximately 40 years ago, the
governments of a number of Eastern European countries expropriated a large
amount of property. The claims of many property owners against those governments
were never finally settled. In


                                       4
<PAGE>

the event of the return to power of the Communist Party, there can be no
assurance that the portfolio's investments in Eastern Europe would not also be
expropriated, nationalized or otherwise confiscated.

In addition, the Equity, Growth, International Equity, Mid Cap Growth, Mid Cap
Value, Small Cap Value, Value, Balanced, Multi-Asset-Class and Balanced Plus
portfolios may invest in Global Depositary Receipts ("GDRs") and European
Depositary Receipts ("EDRs") to the extent that they become available. GDRs and
EDRs are typically issued by foreign depositaries, although they may also be
issued by U.S. depositaries, and evidence ownership interests in a security or
pool of securities issued by either a foreign or a U.S. corporation.

Holders of unsponsored GDRs or EDRs generally bear all the costs associated with
establishing the unsponsored GDRs or EDRs. The depositary of unsponsored GDRs or
EDRs is under no obligation to distribute shareholder communications received
from the underlying issuer or to pass through to the holders of the unsponsored
GDRs or EDRs voting rights with respect to the deposited securities or pool of
securities. GDRs or EDRs are not necessarily denominated in the same currency as
the underlying securities to which they may be connected. Generally, GDRs or
EDRs in registered form are designed for use in the U.S. securities market and
GDRs or EDRs in bearer form are designed for use in securities markets outside
the United States. The Funds may invest in sponsored and unsponsored GDRs or
EDRs. For purposes of the Funds' investment policies, a Funds' investments in
GDRs or EDRs will be deemed to be investments in the underlying securities.

                                FUTURES CONTRACTS

Each Portfolio, except the Cash Reserves Portfolio, may enter into futures
contracts, options, and options on futures contracts. Futures contracts provide
for the future sale by one party and purchase by another party of a specified
amount of a specific security at a specified future time and at a specified
price. Futures contracts which are standardized as to maturity date and
underlying financial instrument are traded on national futures exchanges.
Futures exchanges and trading are regulated under the Commodity Exchange Act by
the Commodity Futures Trading Commission ("CFTC"), a U.S. Government Agency.

Although futures contracts by their terms call for actual delivery or acceptance
of the underlying securities, in most cases the contracts are closed out before
the settlement date without the making or taking of delivery. Closing out an
open futures position is done by taking an opposite position ("buying" a
contract which has previously been "sold" or "selling" a contract previously
"purchased") in an identical contract to terminate the position. Brokerage
commissions are incurred when a futures contract is bought or sold.

Futures traders are required to make a good faith margin deposit in cash or
acceptable securities with a broker or custodian to initiate and maintain open
positions in futures contracts. A margin deposit is intended to assure
completion of the contract (delivery or acceptance of the underlying securities)
if it is not terminated prior to the specified delivery date. Minimal initial
margin requirements are established by the futures exchange and may be changed.
Brokers may establish deposit requirements which are higher than the exchange
minimums. Futures contracts are customarily purchased and sold on the basis of
margin deposits that may range upward from less than 5% of the value of the
contract being traded. A Portfolio's margin deposits will be placed in a
segregated account maintained by the Fund's Custodian or with a Futures 
Commission Merchant as approved by the Fund's Board.

After a futures contract position is opened, the value of the contract is marked
to market daily. If the futures contract price changes to the extent that the
margin on deposit does not satisfy margin requirements, payment of additional
"variation" margin will be required. Conversely, a change in the contract value
may reduce the required margin, resulting in a repayment of excess margin to the
contract holder. Variation margin payments are made to and from the futures
broker for as long as the contract remains open. The Fund expects to earn
interest income on its margin deposits.

Traders in futures contracts may be broadly classified as either "hedgers" or
"speculators." Hedgers use the futures markets primarily to offset unfavorable
changes in the value of securities otherwise held for investment purposes or
expected to be acquired by them. Speculators are less inclined to own the
securities underlying the futures contracts which they trade, and use futures
contracts with the expectation of realizing profits from fluctuations in the
value of the underlying securities. Regulations of the CFTC applicable to the
Fund require that the aggregate initial margins and premiums required to
establish non-hedging positions not exceed 5% of the liquidation value of a
Portfolio.

Although techniques other than the sale and purchase of futures contracts could
be used to control a Portfolio's exposure to market fluctuations, the use of
futures contracts may be a more effective means of hedging this exposure. While
the Portfolios will incur commission expenses in both opening and closing out
futures positions, these costs are lower than transaction costs incurred in the
purchase and sale of the underlying securities.

                  RESTRICTIONS ON THE USE OF FUTURES CONTRACTS

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, and will maintain assets
sufficient to meet its obligations under such contracts in a segregated account
with the custodian bank or will otherwise comply with the SEC's position on
asset coverage.

                      RISK FACTORS IN FUTURES TRANSACTIONS

Positions in futures contracts may be closed out only on an exchange which
provides a secondary market for such futures. However, there can be no assurance
that a liquid secondary market will exist for any particular futures contract at
any specific time. Thus, it may not be possible to close a futures position. In
the event of adverse price movements, a Portfolio would continue to be required
to make daily cash payments to maintain its required margin. In such situations,
if the Portfolio has insufficient cash, it may have to sell portfolio securities
to meet daily margin requirements at a time when it may be disadvantageous to do
so. In addition, the Portfolio may be required to make delivery of the
instruments underlying interest rate futures contracts it holds. The inability
to close options and futures positions also could have an adverse impact on a
Portfolio's ability to effectively hedge. A Portfolio will minimize the risk
that it will be unable to close out a futures contract by only entering into
futures which are traded on national futures exchanges and for which there
appears to be a liquid secondary market.

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

Utilization of futures transactions by a Portfolio does involve the risk of
imperfect or no correlation where the securities underlying futures contracts
have different maturities than the portfolio securities being hedged. It is also
possible that a Portfolio could both lose money on futures contracts and also
experience a decline in value of its portfolio securities. There is also the
risk of loss by a Portfolio of margin deposits in the event of bankruptcy of a
broker with whom the Portfolio has an open position in a futures contract or
related option. Most futures exchanges limit the amount of fluctuation permitted
in futures contract prices during a single trading day. The daily limit
establishes the maximum amount that the price of a futures contract may vary
either up or down from the previous day's settlement price at the end of a
trading session. Once the daily limit has been reached in a particular type of
contract, no trades may be made on that day at a price beyond that limit. The
daily limit governs only price movement during a particular trading day and
therefore does not limit potential losses, because the limit may prevent the
liquidation of unfavorable positions. Futures contract prices have occasionally
moved to the daily limit for several consecutive trading days with little or no
trading, thereby preventing prompt liquidation of futures positions and
subjecting some futures traders to substantial losses.

                                     OPTIONS

Investments in options involve some of the same considerations that are involved
in connection with investments in futures contracts (e.g., the existence of a
liquid secondary market). In addition, the purchase of an option also entails
the risk that changes in the value of the underlying security or contract will
not be fully reflected in the value



                                       6
<PAGE>

of the option purchased. Depending on the pricing of the option compared to
either the futures contract or securities, an option may or may not be less
risky than ownership of the futures contract or actual securities. In general,
the market prices of options can be expected to be more volatile than the market
prices on the underlying futures contract or securities.

OTC Options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC Option, including such terms as method of settlement, term, exercise price,
premium, guarantees and security, are set by negotiation of the parties. The
Portfolios expect generally to enter into OTC Options that have cash settlement
provisions, although it is not required to do so.

Unless the parties provide for it, there is no central clearing or guaranty
function in an OTC Option. As a result, if the Counterparty fails to make or
take delivery of the security, currency or other instrument underlying an OTC
Option it has entered into with a Portfolio or fails to make a cash settlement
payment due in accordance with the terms of that option, the Portfolio will lose
any premium it paid for the option as well as any anticipated benefit of the
transaction. Accordingly, the Adviser must assess the creditworthiness of each
such Counterparty or any guarantor of credit enhancement of the Counterparty's
credit to determine the likelihood that the terms of the OTC Option will be
satisfied. The staff of the SEC currently takes the position that OTC Options
purchased by the Portfolios or sold by them (the cost of the sell-back plus the
in-the-money amount, if any) are illiquid, and are subject to the Portfolio's
limitation on investing in illiquid securities.

The Portfolios may also write covered-call options on foreign currencies for
cross-hedging purposes. A call option on a foreign currency is for cross-hedging
purposes if it is designed to protect against a decline in the U.S. dollar value
of a currency due to the changes of exchange rates vis a vis the U.S. dollar and
the option is written for a currency other than the currency in which the
security is denominated. In such circumstances, the Portfolios will follow the
coverage requirements as described in the preceding paragraph.

                          OPTIONS ON FOREIGN CURRENCIES

All Portfolios except the Cash Reserves, Domestic Fixed Income, Limited
Duration, Mortgage-Backed Securities and Advisory Mortgage Portfolios, may
purchase and write options on foreign currencies in a manner similar to that in
which futures contracts on foreign currencies, or forward contracts, will be
utilized. For example, a decline in the dollar value of a foreign currency in
which portfolio securities are denominated will reduce the dollar value of such
securities, even if their value in the foreign currency remains constant. In
order to protect against such diminution in the value of portfolio securities, a
Portfolio may purchase put options on the foreign currency. If the value of the
currency does decline, a Portfolio will have the right to sell such currency for
a fixed amount in dollars and will thereby offset, in whole or in part, the
adverse effect on its portfolio which otherwise would have resulted.

Conversely, where a rise in the dollar value of a currency in which securities
to be acquired are denominated is projected, thereby increasing the cost of such
securities, a Portfolio may purchase call options thereon. The purchase of such
options could offset, at least partially, the effects of the adverse movements
in exchange rates. As in the case of other types of options, however, the
benefit to a Portfolio derived from purchases of foreign currency options will
be reduced by the amount of the premium and related transaction costs. In
addition, where currency exchange rates do not move in the direction or to the
extent anticipated, the Portfolios could sustain losses on transactions in
foreign currency options which would require them to forego a portion or all of
the benefits of advantageous changes in such rates.

The Portfolios may write options on foreign currencies for the same purposes.
For example, where a Portfolio anticipates a decline in the dollar value of
foreign currency denominated securities due to adverse fluctuations in exchange
rates it could, instead of purchasing a put option, write a call option on the
relevant currency. If the


                                       7
<PAGE>

anticipated decline occurs, the option will most likely not be exercised, and
the diminution in value of portfolio securities will be offset by the amount of
the premium received.

Similarly, instead of purchasing a call option to hedge against an anticipated
increase in the dollar cost of securities to be acquired, a Portfolio could
write a put option on the relevant currency which, if rates move in the manner
projected, will expire unexercised and allow the Portfolios to hedge such
increased cost up to the amount of the premium. As in the case of other types of
options, however, the writing of a foreign currency option will constitute only
a partial hedge up to the amount of the premium, and only if rates move in the
expected direction. If this does not occur, the option may be exercised and the
Portfolios would be required to purchase or sell the underlying currency at a
loss which may not be offset by the amount of the premium. Through the writing
of options on foreign currencies, a Portfolio also may be required to forego all
or a portion of the benefits which might otherwise have been obtained from
favorable movements in exchange rates.

The Portfolios may only write covered call options on foreign currencies. A call
option written on a foreign currency by a Portfolio is "covered" if the
Portfolio owns the underlying foreign currency covered by the call, an absolute
and immediate right to acquire that foreign currency without additional cash
consideration (or for additional cash consideration held in a segregated account
by the Custodian) or upon conversion or exchange of other foreign currency held
in its portfolio. A written call option is also covered if a Portfolio has a
call on the same foreign currency and in the same principal amount as the call
written where the exercise price of the call held (a) is equal to or less than
the exercise price of the call written or (b) is greater than the exercise price
of the call written if the difference is maintained by the Portfolio in cash,
U.S. Government securities or other high grade liquid debt securities in a
segregated account with the Custodian, or (c) maintains in a segregated account
cash, U.S. Government securities or other high-grade liquid debt securities in
an amount not less than the value of the underlying foreign currency in U.S.
dollars, marked-to-market daily.

The Portfolios may also write call options on foreign currencies for
cross-hedging purposes. A call option on a foreign currency is for cross-hedging
purposes if it is designed to provide a hedge against a decline in the U.S.
dollar value of a security which a Portfolio owns or has the right to acquire
due to an adverse change in the exchange rate and which is denominated in the
currency underlying the option. In such circumstances, the Portfolio will either
"cover" the transaction as described above or collateralize the option by
maintaining in a segregated account with the Custodian, cash or liquid
securities in an amount not less than the value of the underlying foreign
currency in U.S. dollars marked-to-market daily.

                              COMBINED TRANSACTIONS

The Portfolios may enter into multiple transactions, including multiple options
transactions, multiple futures transactions, multiple foreign currency
transactions (including forward foreign currency exchange contracts) and any
combination of futures, options and foreign currency transactions, instead of a
single transaction, as part of a single hedging strategy when, in the opinion of
the Adviser, it is in the best interest of the Portfolio to do so. A combined
transaction, while part of a single strategy, may contain elements of risk that
are present in each of its component transactions and will be structured in
accordance with applicable SEC regulations and SEC staff guidelines.

     RISKS OF OPTIONS ON FUTURES CONTRACTS, FORWARD CONTRACTS AND OPTIONS ON
                               FOREIGN CURRENCIES

Options on foreign currencies and forward contracts are not traded on contract
markets regulated by the CFTC or (with the exception of certain foreign currency
options) by the SEC. To the contrary, such instruments are traded through
financial institutions acting as market-makers, although foreign currency
options are also traded on certain national securities exchanges, such as the
Philadelphia Stock Exchange and the Chicago Board Options Exchange,



                                       8

subject to SEC regulation. Similarly, options on currencies may be traded
over-the-counter. In an over-the-counter trading environment, many of the
protections afforded to exchange participants will not be available. For
example, there are no daily price fluctuation limits, and adverse market
movements could therefore continue to an unlimited extent over a period of time.
Although the purchase of an option cannot lose more than the amount of the
premium plus related transaction costs, this entire amount could be lost.
Moreover, the option writer and a trader of forward contracts could lose amounts
substantially in excess of their initial investments, due to the margin and
collateral requirements associated with such positions.

Options on foreign currencies traded on national securities exchanges are within
the jurisdiction of the SEC, as are other securities traded on such exchanges.
As a result, many of the protections provided to traders on organized exchanges
will be available with respect to such transactions. In particular, all foreign
currency option positions entered into on a national securities exchange are
cleared and guaranteed by the Options Clearing Corporation ("OCC"), thereby
reducing the risk of counterparty default. Furthermore, a liquid secondary
market in options traded on a national securities exchange may be more readily
available than in the over-the-counter market, potentially permitting a
Portfolio to liquidate open positions at a profit prior to exercise or
expiration, or to limit losses in the event of adverse market movements.

The purchase and sale of exchange-traded foreign currency options, however, is
subject to the risks of the availability of a liquid secondary market described
above, as well as the risks regarding adverse market movements, margining of
options written, the nature of the foreign currency market, possible
intervention by governmental authorities and the effect of other political and
economic events. In addition, exchange-traded options of foreign currencies
involve certain risks not presented by the over-the-counter market. For example,
exercise and settlement of such options must be made exclusively through the
OCC, which has established banking relationships in applicable foreign countries
for this purpose. As a result, the OCC may, if it determines that foreign
governmental restrictions or taxes would prevent the orderly settlement of
foreign currency option exercises, or would result in undue burdens on the OCC
or its clearing member, impose special procedures on exercise and settlement,
such as technical changes in the mechanics of delivery of currency, the fixing
of dollar settlement prices or prohibitions, on exercise.

In addition, futures contracts, options on futures contracts, forward contracts
and options on foreign currencies may be traded on foreign exchanges. Such
transactions are subject to the risk of governmental actions affecting trading
in or the prices of foreign currencies or securities. The value of such
positions also could be adversely affected by (i) other complex foreign
political and economic factors, (ii) lesser availability than in the United
States of data on which to make trading decision, (iii) delays in the
Portfolio's ability to act upon economic events occurring in foreign markets
during non business hours in the United States, (iv) the imposition of different
exercise and settlement terms and procedures and margin requirements than in the
United States, and (v) lesser trading volume.

                                 SWAP CONTRACTS

All Portfolios, except the Cash Reserves Portfolio, may enter into Swap
Contracts. A swap 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 currencies, fixed interest rates,
prices, total return on interest rate indices, fixed income indices, stock
indices and commodity indices (as well as amounts derived from arithmetic
operations on these indices). For example, a Portfolio may agree to swap the
return generated by a fixed-income index for the return generated by a second
fixed-income index. The currency swaps in which the portfolios may enter will
generally involve an agreement to pay interest streams in one currency based on
a specified index in exchange for receiving interest streams denominated in
another currency. Such swaps may involve initial and final exchanges that
correspond to the agreed upon national amount.




                                       9
<PAGE>

The swaps in which the Portfolios may engage also include rate caps, floors and
collars under which one party pays a single or periodic fixed amount(s) (or
premium), and the other party pays periodic amounts based on the movement of a
specified index. Swaps do not involve the delivery of securities, other
underlying assets, or principal. Accordingly, the risk of loss with respect to
swaps is limited to the net amount of payments that a Portfolio is contractually
obligated to make. If the other party to a swap defaults, a Portfolio's risk of
loss consists of the net amount of payments that a Portfolio is contractually
entitled to receive. Currency swaps usually involve the delivery of the entire
principal value of one designated currency in exchange for the other designated
currency. Therefore, the entire principal value of a currency swap is subject to
the risk that the other party to the swap will default on its contractual
delivery obligations. If there is a default by the counterparty, the Portfolios
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. 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 Portfolios will usually enter into swaps on a net basis, i.e., the two
payment 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 payments. A Portfolio's obligations under
a swap agreement will be accrued daily (offset against any amounts owing to the
Portfolio) and any accrued but unpaid net amounts owed to a swap counterparty
will be covered by the maintenance of a segregated account consisting of cash,
U.S. Government securities, or high grade debt obligations, to avoid any
potential leveraging of the Portfolio. To the extent that these swaps, caps,
floors, and collars are entered into for hedging purposes, the Adviser believes
such obligations do not constitute "senior securities" under the Investment
Company Act of 1940 and, accordingly, will not treat them as being subject to a
Portfolio's borrowing restrictions. All of the portfolios of MAS Funds except
the Cash Reserves Portfolio may enter into OTC Derivatives transactions (Swaps,
Caps, Floors, Puts, etc., but excluding foreign exchange contracts) with
counterparties that are 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.

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.

                  FOREIGN CURRENCY EXCHANGE-RELATED SECURITIES

Foreign currency warrants--Foreign currency warrants are warrants which entitle
the holder to receive from their issuer an amount of cash (generally, for
warrants issued in the United States, in U.S. dollars) which is calculated
pursuant to a predetermined formula and based on the exchange rate between a
specified foreign currency and the U.S. dollar as of the exercise date of the
warrant. Foreign currency warrants generally are exercisable upon their issuance
and expire as of a specified date and time. Foreign currency warrants have been
issued in connection with U.S. dollar-denominated debt offerings by major
corporate issuers in an attempt to reduce the foreign currency exchange risk
which, from the point of view of prospective purchasers of the securities, is
inherent in the international fixed-income marketplace. Foreign currency
warrants may attempt to reduce the foreign exchange risk assumed by purchasers
of a security by, for example, providing for a supplemental payment in the event
that the U.S. dollar depreciates against the value of a major foreign currency
such as the Japanese Yen or German Deutschmark. The formula used to determine
the amount payable upon exercise of a foreign currency warrant may make the
warrant worthless unless the applicable foreign currency exchange rate moves in
a particular direction (e.g., unless the U.S. dollar appreciates or depreciates
against the particular foreign currency to which the warrant



                                       10
<PAGE>

is linked or indexed). Foreign currency warrants are severable from the debt
obligations with which they may be offered, and may be listed on exchanges.
Foreign currency warrants may be exercisable only in certain minimum amounts,
and an investor wishing to exercise warrants who possesses less than the minimum
number required for exercise may be required either to sell the warrants or to
purchase additional warrants, thereby incurring additional transaction costs. In
the case of any exercise of warrants, there may be a time delay between the time
a holder of warrants gives instructions to exercise and the time the exchange
rate relating to exercise is determined, during which time the exchange rate
could change significantly, thereby affecting both the market and cash
settlement values of the warrants being exercised. The expiration date of the
warrants may be accelerated if the warrants should be delisted from an exchange
or if their trading should be suspended permanently, which would result in the
loss of any remaining "time value" of the warrants (i.e., the difference between
the current market value and the exercise value of the warrants), and, in the
case where the warrants were "out-of-the-money," in a total loss of the purchase
price of the warrants. Warrants are generally unsecured obligations of their
issuers and are not standardized foreign currency options issued by the OCC.
Unlike foreign currency options issued by the OCC, the terms of foreign exchange
warrants generally will not be amended in the event of governmental or
regulatory actions affecting exchange rates or in the event of the imposition of
other regulatory controls affecting the international currency markets. The
initial public offering price of foreign currency warrants is generally
considerably in excess of the price that a commercial user of foreign currencies
might pay in the interbank market for a comparable option involving
significantly larger amounts of foreign currencies. Foreign currency warrants
are subject to complex political or economic factors.

Principal exchange rate linked securities--Principal exchange rate linked
securities are debt obligations the principal on which is payable at maturity in
an amount that may vary based on the exchange rate between the U.S. dollar and a
particular foreign currency at or about that time. The return on "standard"
principal exchange rate linked securities is enhanced if the foreign currency to
which the security is linked appreciates against the U.S. dollar, and is
adversely affected by increases in the foreign exchange value of the U.S.
dollar; "reverse" principal exchange rate linked securities are like the
"standard" securities, except that their return is enhanced by increases in the
value of the U.S. dollar and adversely impacted by increases in the value of
foreign currency. Interest payments on the securities are generally made in U.S.
dollars at rates that reflect the degree of foreign currency risk assumed or
given up by the purchaser of the notes (i.e., at relatively higher interest
rates if the purchaser has assumed some of the foreign exchange risk, or
relatively lower interest rates if the issuer has assumed some of the foreign
exchange risk, based of the expectations of the current market). Principal
exchange rate linked securities may in limited cases be subject to acceleration
of maturity (generally, not without the consent of the holders of the
securities), which may have an adverse impact on the value of the principal
payment to be made at maturity.

Performance indexed paper--Performance indexed paper is U.S. dollar-denominated
commercial paper the yield of which is linked to certain foreign exchange rate
movements. The yield to the investor on performance indexed paper is between the
U.S. dollar and a designated currency as of or about that time (generally, the
index maturity two days prior to maturity). The yield to the investor will be
within a range stipulated at the time of purchase of the obligation, generally
with a guaranteed minimum rate of return that is below, and a potential maximum
rate of return that is above, market yields on U.S. dollar-denominated
commercial paper, with both the minimum and maximum rates of return on the
investment corresponding to the minimum and maximum values of the spot exchange
rate two business days prior to maturity.

                                 MUNICIPAL BONDS

Municipal Bonds generally include debt obligations issued by states and their
political subdivisions, and duly constituted authorities and corporations, to
obtain Funds to construct, repair or improve various public facilities such as
airports, bridges, highways, hospitals, housing, schools, streets and water and
sewer works. Municipal Bonds may also be issued to refinance outstanding
obligations as well as to obtain Funds for general operating expenses and for
loans to other public institutions and facilities.


                                       11
<PAGE>

The two principal classifications of Municipal Bonds are "general obligation"
and "revenue" or "special tax" bonds. General obligation bonds are secured by
the issuer's pledge of its full faith, credit and taxing power for the payment
of principal and interest. Revenue or special tax bonds are payable only from
the revenues derived from a particular facility or class of facilities or, in
some cases, from the proceeds of a special excise or other tax, but not from
general tax revenues. The Municipal and PA Municipal Portfolios ("the
Portfolios") may also invest in tax-exempt industrial development bonds,
short-term municipal obligations, project notes, demand notes and tax-exempt
commercial paper.

Industrial revenue bonds in most cases are revenue bonds and generally do not
have the pledge of the credit of the issuer. The payment of the principal and
interest on such industrial revenue bonds is dependent solely on the ability of
the user of the facilities financed by the bonds to meet its financial
obligations and the pledge, if any, of real and personal property so financed as
security for such payment. Short-term municipal obligations issued by states,
cities, municipalities or municipal agencies, include Tax Anticipation Notes,
Revenue Anticipation Notes, Bond Anticipation Notes, Construction Loan Notes and
Short-Term Discount Notes. Project Notes are instruments issued by the
Department of Housing and Urban Development but issued by a state or local
housing agency. While the issuing agency has the primary obligation on such
Project notes, they are also secured by the full faith and credit of the United
States.

Note obligations with demand or put options may have a stated maturity in excess
of one year, but permit any holder to demand payment of principal plus accrued
interest upon a specified number of days' notice. Frequently, such obligations
are secured by letters of credit or other credit support arrangements provided
by banks. The issuer of such notes normally has a corresponding right, after a
given period, to repay at its discretion the outstanding principal of the note
plus accrued interest upon a specific number of days' notice to the bondholders.
The interest rate on a demand note may be based upon a known lending rate, such
as the prime lending rate, and be adjusted when such rate changes, or the
interest rate on a demand note may be a market rate that is adjusted at
specified intervals. Each note purchased by the Portfolios will meet the quality
criteria set out in the Prospectus for the Portfolios.

The yields of Municipal Bonds depend on, among other things, general money
market conditions, conditions in the Municipal Bond market, the size of a
particular offering, the maturity of the obligation, and the rating of the
issue. The ratings of Moody's and Standard & Poor's represent their opinions of
the quality of the Municipal Bonds rated by them. It should be emphasized that
such ratings are general and are not absolute standards of quality.
Consequently, Municipal Bonds with the same maturity, coupon and rating may have
different yields, while Municipal Bonds of the same maturity and coupon, but
with different ratings may have the same yield. It will be the responsibility of
the investment management staff to appraise independently the fundamental
quality of the bonds held by the Portfolios.

Municipal Bonds are sometimes purchased on a "when-issued" basis meaning the
Portfolio has committed to purchase certain specified securities at an agreed
upon price when they are issued. The period between commitment date and issuance
date can be a month or more. It is possible that the securities will never be
issued and the commitment canceled.

From time to time proposals have been introduced before Congress to restrict or
eliminate the Federal income tax exemption for interest on Municipal Bonds.
Similar proposals may be introduced in the future. If any such proposal were
enacted, it might restrict or eliminate the ability of the Portfolios to achieve
their investment objectives. In that event, the Fund's Trustees and officers
would reevaluate its investment objective and policies and consider recommending
to its shareholders changes in such objective and policies.

Similarly, from time to time proposals have been introduced before State and
local legislatures to restrict or eliminate the State and local income tax
exemption for interest on Municipal Bonds. Similar proposals may be


                                       12
<PAGE>

introduced in the future. If any such proposal were enacted, it might restrict
or eliminate the ability of the Portfolio to achieve its investment objective.
In that event, the Fund's Trustees and officers would reevaluate its investment
objective and policies and consider recommending to its shareholders changes in
such objective and policies.

                                    DURATION

The Limited Duration and Intermediate Duration Portfolios seek to achieve their
objective by investing in the types of fixed income securities described in the
Prospectus and by maintaining an average duration of between one and three years
and two and five years, respectively. Duration is one of the fundamental tools
used by the Adviser in security selection for the Portfolios and any other
Portfolio which invests in fixed income securities.

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 the "term of
maturity." Duration incorporates a bond's yield, coupon interest payments, final
maturity and call features into one measure.

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, 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
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 things 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 is not properly captured by duration in
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 more sophisticated analytical
techniques that incorporate the economic life of a security into the
determination of its interest rate exposure.

                           MORTGAGE-BACKED SECURITIES

Mortgage-backed securities represent an ownership interest in a pool of
residential mortgage loans. These securities are designed to provide monthly
payments of interest and principal to the investor. The mortgagor's monthly
payments to his/her lending institution are "passed-through" to investors. Fixed
Income, Domestic Fixed Income, Fixed Income Portfolio II, Special Purpose Fixed
Income, Limited Duration, High Yield, Intermediate Duration Fixed Income,
Mortgage-Backed Securities, Advisory Mortgage, International Fixed Income,
Advisory Foreign Fixed Income, Global Fixed Income, Multi-Asset-Class,
Municipal, PA Municipal, Balanced Plus and Balanced Portfolios may invest in
Mortgage-Backed Securities. Most issuers or poolers provide guarantees of
payments, regardless of whether or not the mortgagor actually makes the payment.
The guarantees made by issuers or poolers are individual loan, title, pool and
hazard insurance purchased by the issuer. There can be no assurance


                                       13
<PAGE>

that the private issuers can meet their obligations under the policies.
Mortgage-backed securities issued by private 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
Portfolios will be rated investment grade by Moody's or Standard & Poor's, or,
if unrated, deemed by the Adviser to be of investment grade quality.

Underlying Mortgages

Pools consist of whole mortgage loans or participation in loans. The majority of
these loans are made to purchasers of 1-4 family homes. The terms and
characteristics of the mortgage instruments are generally uniform within a pool
but may vary among pools. For example, in addition to fixed-rate fixed-term
mortgages, the Portfolios may purchase pools of adjustable rate mortgages (ARM),
growing equity mortgages (GEM), graduated payment mortgage (GPM) and other types
where the principal and interest payment procedures vary. ARM's are mortgages
which reset the mortgage's interest rate with changes in open market interest
rates. The Portfolios' interest income will vary with changes in the applicable
interest rate on pools of ARM's. GPM and GEM pools maintain constant interest
rates, with varying levels of principal repayment over the life of the mortgage.
These different interest and principal payment procedures should not impact the
Portfolios' net asset values since the prices at which these securities are
valued each day will reflect the payment procedures.

All poolers apply standards for qualifications to local lending institutions
which originate mortgages for the pools. Poolers also establish credit standards
and underwriting criteria for individual mortgages included in the pools. In
addition, many mortgages included in pools are insured through private mortgage
insurance companies.

Average Life

The average life of pass-through pools varies with the maturities, coupon rates,
and type of the underlying mortgage instruments. In addition, a pool's term may
be shortened by unscheduled or early payments of principal and interest on the
underlying mortgages. The occurrence of mortgage prepayments is affected by
factors including the level of interest rates, general economic conditions, the
location and age of the mortgage and other social and demographic conditions.

Returns of Mortgage-Backed Securities

Yields on mortgage-backed pass-through securities are typically quoted based on
a prepayment assumption derived from the coupon and maturity of the underlying
instruments. Actual pre-payment experience may cause the realized return to
differ from the assumed yield. Reinvestment of pre-payments may occur at higher
or lower interest rates than the original investment, thus affecting the
realized returns of the Portfolios. The compounding effect from reinvestment of
monthly payments received by each Portfolio will increase its return to
shareholders, compared to bonds that pay interest semi-annually.

About Mortgage-Backed Securities

Interests in pools of mortgage-backed securities differ from other forms of debt
securities, which normally provide for periodic payment of interest in fixed
amounts with principal payments at maturity or specified call dates. Instead,
these securities provide a monthly payment which consists of both interest and
principal payments. In effect, these payments are a "pass-through" of the
monthly payments made by the individual borrowers on their residential mortgage
loans, net of any fees paid to the issuer or guarantor of such securities.
Additional payments are caused by repayments resulting from the sale of the
underlying residential property, refinancing or foreclosure net of fees or costs
which may be incurred. Some mortgage-backed securities are described as
"modified pass- through." These securities entitle the holders to receive all
interest and principal payments owed on the mortgages in the pool, net of
certain fees, regardless of whether or not the mortgagors actually make payment.


                                       14
<PAGE>

Residential mortgage loans are pooled by the Federal Home Loan Mortgage
Corporation (FHLMC). FHLMC is a corporate instrumentality of the U.S. Government
and was created by Congress in 1970 for the purpose of increasing the
availability of mortgage credit for residential housing. FHLMC issues
Participation Certificates ("PC's") which represent interests in mortgages from
FHLMC's national portfolio. FHLMC guarantees the timely payment of interest and
ultimate collection of principal.

The Federal National Mortgage Association (FNMA) is a Government-sponsored
corporation owned entirely by private stockholders. It is subject to general
regulation by the Secretary of Housing and Urban Development. FNMA purchases
residential mortgages from a list of approved seller/servicers which include
state and federally- chartered savings and loan associations, mutual savings,
banks, commercial banks and credit unions and mortgage bankers. Pass-through
securities issued by FNMA are guaranteed as to timely payment of principal and
interest by FNMA.

The principal Government guarantor of mortgage-backed securities is the
Government National Mortgage Association (GNMA). GNMA is a wholly-owned U.S.
Government corporation within the Department of Housing and Urban Development.
GNMA is authorized to guarantee, with the full faith and credit of the U.S.
Government, the timely payment of principal and interest on securities issued by
approved institutions and backed by pools of FHA-insured or VA-guaranteed
mortgages.

Commercial banks, savings and loan institutions, private mortgage insurance
companies, mortgage bankers and other secondary market issuers also create
pass-through pools of conventional residential mortgage loans. Pools created by
such non-governmental issuers generally offer a higher rate of interest than
Government and Government-related pools because there are no direct or indirect
Government guarantees of payments in the former pools. However, timely payment
of interest and principal of these pools is supported by various forms of
insurance or guarantees, including individual loan, title, pool and hazard
insurance purchased by the issuer. The insurance and guarantees are issued by
Governmental entities, private insurers and the mortgage poolers. There can be
no assurance that the private insurers can meet their obligations under the
policies. Mortgage-backed securities purchased for the Portfolios will, however,
be rated of investment grade quality by Moody's and/or Standard & Poor's or, if
unrated, deemed by the Adviser to be of investment grade quality.

It is expected that Governmental or private entities may create mortgage loan
pools offering pass-through investments in addition to those described above.
The mortgages underlying these securities may be alternative mortgage
instruments, that is, mortgage instruments whose principal or interest payment
may vary or whose terms to maturity may be shorter than previously customary. As
new types of mortgage-backed securities are developed and offered to investors,
the Portfolios will, consistent with their investment objective and policies,
consider making investments in such new types of securities.

                       STRIPPED MORTGAGE-BACKED SECURITIES

Stripped mortgage-backed securities ("SMBS") are derivative multiclass mortgage
securities. SMBS may be issued by agencies or instrumentalities of the U.S.
Government or by 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. A
common 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 the most extreme
case, 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 an IO class 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


                                       15
<PAGE>

on a Portfolio yield to maturity from these securities. 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.

                           U.S. GOVERNMENT SECURITIES

The term "U.S. Government securities" refers to a variety of securities which
are issued or guaranteed by the United States Government, and by various
instrumentalities which have been established or sponsored by the United States
Government. U.S. Treasury securities are backed by the "full faith and credit"
of the United States.

Agency Securities: Securities issued or guaranteed by Federal agencies and U.S.
Government sponsored instrumentalities may or may not be backed by the full
faith and credit of the United States. In the case of securities not backed by
the full faith and credit of the United States, the investor must look
principally to the agency or instrumentality issuing or guaranteeing the
obligation for ultimate repayment, and may not be able to assert a claim against
the United States itself in the event the agency or instrumentality does not
meet its commitment. Agencies which are backed by the full faith and credit of
the United States include the Export Import Bank, Farmers Home Administration,
Federal Financing Bank, and others. Certain debt issued by Resolution Funding
Corporation has both its principal and interest backed by the full faith and
credit of the U.S. Treasury in that its principal is defeased by U.S. Treasury
zero coupon issues, while the U.S. Treasury is explicitly required to advance
funds sufficient to pay interest on it, if needed. Certain agencies and
instrumentalities, such as the Government National Mortgage Association, are, in
effect, backed by the full faith and credit of the United States through
provisions in their charters that they may make "indefinite and unlimited"
drawings on the Treasury, if needed to service its debt. Debt from certain other
agencies and instrumentalities, including the Federal Home Loan Bank and Federal
National Mortgage Association, are not guaranteed by the United States, but
those institutions are protected by the discretionary authority of the U.S.
Treasury to purchase certain amounts of their securities to assist the
institution in meeting its debt obligations. Finally, other agencies and
instrumentalities, such as the Farm Credit System and the Federal Home Loan
Mortgage Corporation, are federally chartered institutions under Government
supervision, but their debt securities are backed only by the credit worthiness
of those institutions, not the U.S. Government.

Some of the U.S. Government agencies that issue or guarantee securities include
the Export-Import Bank of the United States, Farmers Home Administration,
Federal Housing Administration, Maritime Administration, Small Business
Administration and The Tennessee Valley Authority.

An instrumentality of the U.S. Government is a Government agency organized under
Federal charter with Government supervision. Instrumentalities issuing or
guaranteeing securities include, among others, Federal Home Loan Banks, the
Federal Land Banks, Central Bank for Cooperatives, Federal Intermediate Credit
Banks and the Federal National Mortgage Association.

                                ZERO COUPON BONDS

Zero Coupon bonds, are a term used to describe notes and bonds which have been
stripped of their unmatured interest coupons, or the coupons themselves, and
also receipts or certificates representing interest in such stripped debt
obligations and coupons. The timely payment of coupon interest and principal on
these instruments remains guaranteed by the "full faith and credit" of the
United States Government.



                                       16
<PAGE>

A zero coupon bond does not pay interest. Instead, it is issued at a substantial
discount to its "face value"--what it will be worth at maturity. The difference
between a security's issue or purchase price and its face value represents the
imputed interest an investor will earn if the security is held until maturity.
For tax purposes, a portion of this imputed interest is deemed as income
received by zero coupon bondholders each year. The Fund, which expects to
qualify as a regulated investment company, intends to pass along such interest
as a component of the Portfolio's distributions of net investment income.

Zero coupon bonds may offer investors the opportunity to earn higher yields than
those available on U.S. Treasury bonds of similar maturity. However, zero coupon
bond prices may also exhibit greater price volatility than ordinary debt
securities because of the manner in which their principal and interest is
returned to the investor.

Zero Coupon Treasury Bonds are sold under a variety of different names, such as:
Certificate of Accrual on Treasury Securities (CATS), Treasury Receipts (Trs),
Separate Trading of Registered Interest and Principal of Securities (STRIPS) and
Treasury Investment Growth Receipts (TIGERS).

                        EURODOLLAR AND YANKEE OBLIGATIONS

Eurodollar bank obligations are dollar-denominated certificates of deposit and
time deposits issued outside the U.S. capital markets by foreign branches of
U.S. banks and by foreign banks. Yankee bank obligations are dollar- denominated
obligations issued in the U.S. capital markets by foreign banks.

Eurodollar and Yankee obligations are subject to the same risks that pertain to
domestic issues, notably credit risk, market risk and liquidity risk.
Additionally, Eurodollar (and to a limited extent, Yankee) obligations are
subject to certain sovereign risks. One such risk is the possibility that a
sovereign country might prevent capital, in the form of dollars, from flowing
across their borders. Other risks include: adverse political and economic
developments; the extent and quality of government regulation of financial
markets and institutions; the imposition of foreign withholding taxes, and the
expropriation or nationalization of foreign issuers. However, Eurodollar and
Yankee obligations held in the Cash Reserves Portfolio will undergo the same
credit analysis as domestic issues in which the Cash Reserves Portfolio invests,
and will have at least the same financial strength as the domestic issuers
approved for the Cash Reserves Portfolio.

                                   BRADY BONDS

A portion of certain of the Fund's fixed-income investments may be invested in
certain debt obligations customarily referred to as "Brady Bonds", which are
created through the exchange of existing commercial bank loans to foreign
entities for new obligations in connection with debt restructuring under a plan
introduced by former U.S. Secretary of the Treasury, Nicholas F. Brady (the
"Brady Plan").

Brady Bonds have been issued only recently, and, accordingly, do not have a long
payment history. They may be collateralized or uncollateralized and issued in
various currencies (although most are dollar-denominated) and they are actively
traded in the over-the-counter secondary market.

Dollar-denominated, collateralized Brady Bonds, which may be fixed rate par
bonds or floating rate discount bonds, are generally collateralized in full as
to principal due at maturity by U.S. Treasury zero coupon obligations which have
the same maturity as the Brady Bonds. Interest payments on these Brady Bonds
generally are collateralized by cash or securities in an amount that, in the
case of fixed rate bonds, is equal to at least one year of rolling interest
payments or, in the case of floating rate bonds, initially is equal to at least
one year's rolling interest payments based on the applicable interest rate at
that time and is adjusted at regular intervals thereafter. Certain Brady Bonds
are entitled to "value recovery payments" in certain circumstances, which in
effect constitute supplemental interest payments but generally are not
collateralized. Brady Bonds are often viewed as having three or four valuation



                                       17
<PAGE>

components: (i) the collateralized repayment of principal at final maturity;
(ii) the collateralized interest payments; (iii) the uncollateralized interest
payments; and (iv) any uncollateralized repayment of principal at maturity
(these uncollateralized amounts constitute the "residual risk"). In the event of
a default with respect to Collateralized Brady Bonds as a result of which the
payment obligations of the issuer are accelerated, the U.S. Treasury zero coupon
obligations held as collateral for the payment of principal will not be
distributed to investors, nor will such obligations be sold and the proceeds
distributed. The collateral will be held by the collateral agent to the
scheduled maturity of the defaulted Brady Bonds, which will continue to be
outstanding, at which time the face amount of the collateral will equal the
principal payments which would have then been due on the Brady Bonds in the
normal course. In addition, in light of the residual risk of the Brady Bonds
and, among other factors, the history of default with respect to commercial bank
loans by public and private entities of countries issuing Brady Bonds,
investments in Brady bonds are to be viewed as speculative.

Brady Plan debt restructurings totaling approximately $73 billion have been
implemented to date in Argentina, Costa Rica, Mexico, Nigeria, the Philippines,
Uruguay and Venezuela, with the largest proportion of Brady Bonds having been
issued to date by Mexico and Venezuela. Brazil has announced plans to issue
Brady Bonds aggregating approximately $35 billion, based on current estimates.
There can be no assurance that the circumstances regarding the issuance of Brady
Bonds by these countries will not change.

                             CASH RESERVES PORTFOLIO

A-1 and Prime-1 Commercial Paper Ratings: Commercial paper rated A-1 by Standard
& Poor's has the following characteristics: (1) liquidity ratios are adequate to
meet cash requirements; (2) long-term senior debt is rated "A" or better; (3)
the issuer has access to at least two additional channels of borrowing; (4)
basic earnings and cash flow have an upward trend with allowance made for
unusual circumstances; (5) typically, the issuer's industry is well established
and the issuer has a strong position within the industry; and (6) the
reliability and quality of management are unquestioned. Relative strength or
weakness of the above factors determine whether the issuer's commercial paper is
A-1, A-2, or A-3. The rating Prime-1 is the highest commercial paper rating
assigned by Moody's. Among the factors considered by Moody's in assigning
ratings are the following: (1) evaluation of the management of the issuer; (2)
economic evaluation of the issuer's industry or industries and the appraisal of
speculative-type risks which may be inherent in certain areas; (3) evaluation of
the issuer's products in relation to competition and customer acceptance; (4)
liquidity; (5) amount and quality of long-term debt; (6) trend of earnings over
a period of ten years; (7) financial strength of a parent company and the
relationships which exist with the issuer; and (8) recognition by the management
of obligations which may be present or may arise as a result of public interest
questions and preparations to meet such obligations.

                               TAX CONSIDERATIONS

In order for a Portfolio to continue to qualify for Federal income tax treatment
as a regulated investment company, at least 90% of its gross income for a
taxable year must be derived from qualifying income; i.e., dividends, interest,
income derived from loans of securities, and gains from the sale of securities
or foreign currencies, or other income derived with respect to its business of
investing in such securities or currencies. In addition, gains realized on the
sale or other disposition of securities or foreign currencies not directly
related to the company's principal business of investing in securities held for
less than three months must be limited to less than 30% of the Portfolio's
annual gross income. It is anticipated that any net gain realized from the
closing out of futures contracts will be considered gain from the sale of
securities and therefore be qualifying income for purposes of the 90%
requirement. In order to avoid realizing excessive gains on securities held less
than three months, the Portfolio may be required to defer the closing out of
futures contracts beyond the time when it would otherwise be advantageous to do
so. It is anticipated that unrealized gains on futures contracts, which have
been open for less than three months as of the end of the Portfolio's fiscal
year and which are recognized for tax purposes, will not be considered gains on
securities held less than three months for the purpose of the 30% test.


                                       18
<PAGE>

Each Portfolio of the Fund will distribute to shareholders annually any net
capital gains which have been recognized for Federal income tax purposes
including unrealized gains at the end of the Portfolio's fiscal year on futures
transactions. Such distributions will be combined with distributions of capital
gains realized on the Portfolio's other investments and shareholders will be
advised of the nature of the payments.

The 30% limit on gains from the disposition of certain options, futures, forward
contracts, and swap contracts held less than three months, and the qualifying
income and diversification requirements applicable to a Portfolio's assets, may
limit the extent to which a Portfolio will be able to engage in these
transactions.

Some of the options, futures contracts, forward contracts, and swap contracts
entered into by the Portfolios may be "Section 1256 contracts." Section 1256
contracts held by a Portfolio at the end of its taxable year (and, for purposes
of the 4% excise tax, on certain other dates as prescribed under the Code) are
"marked to market" with unrealized gains or losses treated as though they were
realized. Any gains or losses, including "marked to market" gains or losses, on
Section 1256 contracts other than forward contracts are generally 60% long-term
and 40% short-term capital gains or losses ("60/40") although all foreign
currency gains and losses from such contracts may be treated as ordinary in
character absent a special election.

Generally, hedging transactions and certain other transactions in options,
futures, forward contracts and swap contracts undertaken by a Portfolio, may
result in "straddles" for U.S. federal income tax purposes. The straddle rules
may affect the character of gain or loss realized by a Portfolio. In addition,
losses realized by a Portfolio on positions that are part of a straddle may be
deferred under the straddle rules, rather than being taken into account in
calculating the taxable income for the taxable year in which such losses are
realized. Because only a few regulations implementing the straddle rules have
been promulgated, the tax consequences of transactions in options, futures,
forward contracts, and swap agreements to a Portfolio are not entirely clear.
The transactions may increase the amount of short-term capital gain realized by
a Portfolio. Short-term capital gain is taxed as ordinary income when
distributed to shareholders.

A Portfolio may make one or more of the elections available under the Code which
are applicable to straddles. If a Portfolio makes any of the elections, the
amount, character, and timing of the recognition of gains or losses from the
affected straddle positions will be determined under rules that vary according
to the elections made. The rules applicable under certain of the elections
operate to accelerate the recognition of gains or losses from the affected
straddle positions.

Because application of the straddle rules may affect the character of gains or
losses, defer losses and/or accelerate the recognition of gains or losses from
the affected straddle positions, the amount which must be distributed to
shareholders, and which will be taxed to shareholders as ordinary income or
long-term capital gain, may be increased or decreased substantially as compared
to a Portfolio that did not engage in such hedging transactions.

                               PURCHASE OF SHARES

Each Portfolio reserves the right in its sole discretion (i) to suspend the
offering of its shares (ii) to reject purchase orders, (iii) to reduce or waive
the minimum for initial and subsequent investments. The Officers of the Fund may
from time to time waive the minimum initial and subsequent investment
requirements in connection with investments in the Fund by employees of the
Adviser and its affiliates.

<PAGE>

                              REDEMPTION OF SHARES

Each Portfolio may suspend redemption privileges or postpone the date of payment
(i) during any period that the New York Stock Exchange is closed, or trading on
the Exchange is restricted as determined by the Commission, (ii) during any
period when an emergency exists as defined by the rules of the Commission as a
result of which it is not reasonably practicable for a Portfolio to dispose of
securities owned by it, or fairly to determine the value of its assets, and
(iii) for such other periods as the Commission may permit.

The Fund has made an election with the Commission pursuant to Rule 18f-1 under
the Investment Company Act of 1940 to pay in cash all redemptions requested by
any shareholder of record limited in amount during any 90-day period to the
lesser of $250,000 or 1% of the net assets of the Portfolio at the beginning of
such period. Such commitment is irrevocable without the prior approval of the
Commission. Redemptions in excess of the above limits may be paid in whole or in
part in investment securities or in cash, as the Trustees may deem advisable;
however, payment will be made wholly in cash unless the Trustees believe that
economic or market conditions exist which would make such a practice detrimental
to the best interests of the Fund. If redemptions are paid in investment
securities, such securities will be valued as set forth in the Fund's Prospectus
under "Valuation of Shares" and a redeeming shareholder would normally incur
brokerage expenses in converting these securities to cash.

No charge is made by a Portfolio for redemptions. Redemption proceeds may be
more or less than the shareholder's cost depending on the market value of the
securities held by the Portfolio.

                              SHAREHOLDER SERVICES

Exchange Privilege


The exchange privilege is only available with respect to Portfolios that are
registered for sale in a shareholder's state. Exchange requests should be sent
to MAS Funds, c/o Miller Anderson & Sherrerd, LLP, One Tower Bridge, West
Conshohocken, PA 19428-0868. Any such exchange will be based on the respective
net asset values of the shares involved. Before making an exchange, a
shareholder should consider the investment objectives of the Portfolio to be
purchased. Exchange requests may be made either by mail or telephone. Telephone
exchanges (referred to as "expedited exchanges") will be accepted only if the
certificates for the shares to be exchanged are held by the Fund for the account
of the shareholder and the registration of the two accounts are identical.
Requests for expedited exchanges received prior to 12:00 p.m. for the Cash
Reserves Portfolio and prior to 4:00 p.m. (Eastern time) for all other
Portfolios will be processed as of the close of business on the same day.
Requests received after these times will be processed on the next business day.
Expedited exchanges may also be subject to limitations as to amounts or
frequency, and to other restrictions established by the Board of Trustees to
assure that such exchanges do not disadvantage the Fund and its shareholders.
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. 

For Federal income tax purposes, an exchange between Portfolios of the Fund is a
taxable event, and, accordingly, a capital gain or loss may be realized. In a
revenue ruling relating to circumstances similar to the Fund's, an exchange
between a series of a Fund was also deemed to be a taxable event. It is likely,
therefore, that a capital gain or loss would be realized on an exchange between
Portfolios; you may want to consult your tax adviser for further information in
this regard. The exchange privilege may be modified or terminated at any time.

Transfer of Shares

Shareholders may transfer shares of the Fund's Portfolios to another person by
written request to the Client Services Group at the address noted above. The
request should clearly identify the account and number of shares to be
transferred and include the signature of all registered owners and all share
certificates, if any, which are subject to the transfer. The signature on the
letter of request, the share certificate or any stock power must be guaranteed
in the same manner as described under "Redemption of Shares." As in the case of
redemptions, the written request must be received in good order before any
transfer can be made.

                             INVESTMENT LIMITATIONS

Each Portfolio of the Fund is subject to the following restrictions which are
fundamental policies and may not be changed without the approval of the lesser
of: (1) at least 67% of the voting securities of the Portfolio present at a
meeting if the holders of more than 50% of the outstanding voting securities of
the Portfolio are present or represented by proxy, or (2) more than 50% of the
outstanding voting securities of the Portfolio.

As a matter of fundamental policy, each Portfolio will not:

(1) invest in physical commodities or contracts on physical commodities;

(2) purchase or sell real estate, although it may purchase and sell securities
of companies which deal in real estate, other than real estate limited
partnerships, and may purchase and sell marketable securities which are secured
by interests in real estate;

(3) make loans except: (i) by purchasing debt securities in accordance with its
investment objectives and policies, or entering into repurchase agreements,
subject to the limitations on investment in illiquid securities described in 
non-fundamental limitation (7), below, (ii) by lending its portfolio securities,
and (iii) by lending portfolio assets to other Portfolios of the Fund, so long 
as such loans are not inconsistent with the Investment Company Act of 1940, as 
amended (the "1940 Act"), or the Rules and Regulations, or interpretations or 
orders of the Securities and Exchange Commission thereunder;

(4) with respect to 75% of its assets, purchase a security if, as a result, it
would hold more than 10% (taken at the time of such investment) of the
outstanding voting securities of any issuer (this restriction is not applicable
to the Global Fixed Income, International Fixed Income, Advisory Foreign Fixed
Income or the Emerging Markets Portfolios);

(5) with respect to 75% of its assets, purchase securities of any issuer if, as
a result, more than 5% of the Portfolio's total assets, taken at market value at
the time of such investment, would be invested in the securities of such issuer
except that this restriction does not apply to securities issued or guaranteed
by the U.S. Government or its agencies or instrumentalities (this restriction
does not apply to the Global Fixed Income, International Fixed Income, Advisory
Foreign Fixed Income or the Emerging Markets Portfolios);

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

(7) underwrite the securities of other issuers (except to the extent that the
fund may be deemed to be an underwriter within the meaning of the Securities Act
of 1933 in connection with the disposition of restricted securities);

(8) acquire any securities of companies within one industry, other than
mortgage-backed securities in the case of the Mortgage-Backed Securities and
Advisory Mortgage Portfolios, if as a result of such acquisition, more than


                                       21
<PAGE>

25% of the value of the Portfolio's total assets would be invested in securities
of companies within such industry; provided, however, that there shall be no
limitation on the purchase of obligations issued or guaranteed by the U.S.
Government, its agencies or instrumentalities, when any such Portfolio adopts a
temporary defensive position. Additionally, the Cash Reserves Portfolio may
invest without limitation in obligations of the U.S. Government or its agencies
and instrumentalities or certificates of deposit or bankers' acceptance of
domestic banks;

Each Portfolio is also subject to the following restrictions which may be
changed by the Board of Trustees without shareholder approval.

As a matter of non-fundamental policy, no Portfolio will:

(1) enter into futures contracts to the extent that each Portfolio's outstanding
obligations to purchase securities under these contracts in combination with its
outstanding obligations with respect to options transactions would exceed 50% of
each Portfolio's total assets, and will maintain assets sufficient to meet its
obligations under such contracts in a segregated account with the custodian bank
or will otherwise comply with the SEC's position on asset coverage;

(2) write put or call options except to the extent described above in (1);

(3) purchase on margin, except for use of short-term credit as may be necessary
for the clearance of purchases and sales of securities, provided that each
Portfolio may make margin deposits in connection with transactions in options,
futures, and options on futures;

(4) sell short unless, the Portfolio (i) by virtue of its ownership of other
securities, has the right to obtain securities equivalent in kind and amount to
the securities sold and, if the right is conditional, the sale is made upon the
same conditions, or (ii) maintains in a segregated account on the books of the
Fund's custodian an amount that, when combined with the amount of collateral
deposited with the broker in connection with the short sale, equals the current
market value of the security sold short or such other amount as the SEC or its
staff may permit by rule, regulation, order or interpretation (transactions in
futures contracts and options, however, are not deemed to constitute selling
securities short);

(5) borrow money other than from banks or other Portfolios of MAS Funds,
provided that a Portfolio may borrow from banks or other Portfolios of MAS Funds
so long as such borrowing is not inconsistent with the 1940 Act or the rules,
regulations, interpretations or orders of the SEC and its staff thereunder; or
purchase additional securities when borrowings exceed 5% of total (gross)
assets;

(6) pledge, mortgage or hypothecate assets in an amount greater than 50% of its
total assets, provided that each Portfolio may segregate assets without limit in
order to comply with the requirements of Section 18(f) of the 1940 Act and
applicable rules, regulations or interpretations of the SEC and its staff;

(7) invest more than an aggregate of 15% of the net assets of the Portfolio,
determined at the time of investment, in illiquid securities provided that this
limitation shall not apply to any investment in securities that are not
registered under the 1933 Act but that can be sold to qualified institutional
investors in accordance with Rule 144A under the 1933 Act and are determined to
be liquid securities under guidelines or procedures adopted by the Board of
Directors;

(8) invest for the purpose of exercising control over management of any company;
and

(9) invest its assets in securities of any investment company, except as
permitted by the 1940 Act or the rules, regulations, interpretations or orders
of the SEC and its staff thereunder.


                                       22
<PAGE>

Unless otherwise indicated, if a percentage limitation on investment or
utilization of assets as set forth above is adhered to at the time an investment
is made, a later change in percentage resulting from changes in the value or
total cost of the Portfolio's assets will not be considered a violation of the
restriction, and the sale of securities will not be required.

Remuneration of Trustees and Officers


The Fund pays each Trustee, who is not also an officer or affiliated person, a
fee for each Board of Trustees Meeting attended plus travel and other expenses
incurred in attending such meetings. Trustees who are also officers or
affiliated persons receive no remuneration for their service as Trustees. The
Fund's officers and employees are paid by the Adviser or Sub-Administrator.
During the fiscal year ended September 30, 1996, the Fund paid $255,969 in fees
and expenses to its "non-interested" Trustees.

The Fund maintains an unfunded Deferred Compensation Plan ("Plan") which allows
each independent Trustee to defer payment of his or her retainer and fees to a
later date. The Fund's policy is for each Trustee to defer at least twenty-five
percent (25%) of his or her retainer and fees received annually from the Fund.
To that end, the Plan requires that each Eligible Trustee (defined by the Plan
as a member of the Board of Trustees who is not an "interested person" of the
Fund, as such term is defined under Section 2(a)(19) of the Investment Company
Act of 1940) defer his or her entire retainer, which is deemed a deferral of
twenty-five percent (25%) of the Trustee's retainer and fees received from the
Fund for the year. The Plan also permits the Eligible Trustee to defer all, or a
portion, of the fees received for attending meetings of the Board of Trustees
throughout the year. Amounts deferred by each Eligible Trustee are credited with
a return equal to what those amounts would have received if they had been
invested in portfolios of the Fund selected by that Trustee. Any deferred
amounts will not be available to Eligible Trustees for a period of two (2) years
and distributions may not be deferred beyond the Eligible Trustee's membership
on the Board of Trustees. Distributions to an Eligible Trustee are either in the
form of a lump sum or equal annual installments over a period of five (5) years
and commence within ninety (90) days after the last date during the deferral
period on which the Fund makes a valuation of the Eligible Trustee's deferred
compensation. The Fund intends that the Plan shall be maintained at all times on
an unfunded basis for federal income tax purposes under the Internal Revenue
Code of 1986. The rights of an Eligible Trustee and the beneficiaries to the
amounts held under the Plan are unsecured and such amounts are subject to the
claims of the creditors of the Fund. The Plan became effective May 23, 1996.
There were no payments under the plan during the fiscal year ended September 30,
1996.

The aggregate compensation paid by the Fund to each of the Trustees during its
fiscal year ended September 30, 1996 is set forth below.

                               DISTRIBUTION PLANS

The Fund's Distribution Plan provides that the Adviser Class Shares will pay MAS
Fund Distribution, Inc. (the "Distributor") an annualized fee of .25% of the
average daily net assets of each Portfolio attributable to Adviser Class Shares,
which the Distributor can use to compensate broker/dealers and service providers
which provide distribution services to Adviser Class Shareholders or their
customers who beneficially own Adviser Class Shares. 

The Fund has adopted the Distribution Plan in accordance with the provisions of
Rule 12b-1 under the 1940 Act which regulates circumstances under which an
investment company may directly or indirectly bear expenses relating to the
distribution of its shares. Continuance of the Plan must be approved annually by
a majority of the Trustees of the Fund and the Trustees who are not "interested
persons" of the Fund within the meaning of the Investment Company Act of 1940.
The Plan requires that quarterly written reports of amounts spent under the Plan
and the purposes of such expenditures be furnished to and reviewed by the
Trustees. The Plan may not be amended to increase materially the amount which
may be spent thereunder without approval by a majority of the outstanding
Adviser Class Shares of the Fund. All material amendments of the Plan will
require approval by a majority of the Trustees of the Fund and of the Trustees
who are not "interested persons" of the Fund. For the fiscal year ended
September 30, 1996, the Value Portfolio paid $855 in distribution fees pursuant
to the Distribution Plan.


                          SHAREHOLDER SERVICE AGREEMENT

The Fund has entered into a Shareholder Service Agreement with the Distributor
whereby the Distributor will compensate service providers who provide certain
services to clients who beneficially own Investment Class shares of the
Portfolios described in the Investment Class prospectus. Each Portfolio will pay
to the Distributor a fee at the annual rate of .15% of the average daily net
assets of such Portfolio attributable to the shares serviced by the service
provider, which fee will be computed daily and paid monthly. During the fiscal
year ended September 30, 1996, the Fund paid $5,739 to compensate the
Distributor under this Shareholder Service Agreement. 

                               INVESTMENT ADVISER

Under an Investment Advisory Agreement ("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 for investment securities.

As compensation for the services rendered by the Adviser under the Agreement and
the assumption by the Adviser of the expenses related thereto (other than the
cost of securities purchased for the Portfolios and the taxes and brokerage
commissions, if any, payable in connection with the purchase and/or sale of such
securities), each Portfolio pays the Adviser an advisory fee calculated by
applying a quarterly rate, based on the following annual percentage rates, to
the Portfolio's average daily net assets for the quarter:

                                                       Rate

In cases where a shareholder of any of the Portfolios has an investment
counseling relationship with the Adviser, the Adviser may, at its discretion,
reduce the shareholder's investment counseling fees by an amount equal to the
pro-rata advisory fees paid by the Fund. This procedure will be utilized with
clients having contractual relationships based on total assets managed by Miller
Anderson & Sherrerd, LLP to avoid situations where excess advisory fees might be
paid to the Adviser. In no event will a client pay higher total advisory fees as
a result of the client's investment in the Fund. In addition, the Adviser has
voluntarily agreed to waive its advisory fees to the extent necessary, if any,
to keep the Institutional Class Shares of the Emerging Markets, Mid Cap Value,
Cash Reserves, Domestic Fixed Income, Intermediate Duration, Limited Duration,
Mortgage-Backed Securities, Municipal, PA Municipal, Multi-Asset-Class, Advisory
Foreign Fixed Income and Advisory Mortgage Portfolios' total annual operating
expenses from exceeding 1.180%, .880%, .320%, .500%, .520%, .420%, .500%, .500%,
 .500%, .780%, .150% and .080% of its average daily net assets, respectively.


For the fiscal years ended September 30, 1994, 1995 and 1996, the Fund paid the
following advisory fees:

agreement or "interested persons" (as defined in the 1940 Act, as amended) of
any such party in person at a meeting called for the purpose of considering such
approval. In addition, the question of continuance of the Agreement may be
presented to the shareholders of the Fund; in such event, continuance shall be
effected only if approved by the affirmative vote of a majority of the
outstanding voting securities of each Portfolio of the Fund. If the holders of
any Portfolio fail to approve the Agreement, the Adviser may continue to serve
as investment adviser to each Portfolio which approved the Agreement, and to any
Portfolio which did not approve the Agreement until new arrangements have been
made. The Agreement is automatically terminated if assigned, and may be
terminated by any Portfolio without penalty, at any time, (1) by vote of the
Board of Trustees or by vote of the outstanding voting securities of the
Portfolio (2) or sixty (60) days' written notice to the Adviser, or (3) by the
Adviser upon ninety (90) days' written notice to the Fund.

The Fund bears all of its own costs and expenses, including but not limited to:
services of its independent accountants, its administrator and dividend
disbursing and transfer agent, legal counsel, taxes, insurance premiums, costs
incidental to meetings of its shareholders and Trustees, the cost of filing its
registration statements under Federal and State securities laws, reports to
shareholders, and custodian fees. These Fund expenses are, in turn, allocated to
each Portfolio, based on their relative net assets. Each Portfolio bears its own
advisory fees and brokerage commissions and transfer taxes in connection with
the acquisition and disposition of its investment securities.

                                 ADMINISTRATION

MAS also serves as Administrator to the Fund pursuant to an Administration
Agreement dated as of November 18, 1993. Chase Global Funds Services (formerly
Mutual Fund Services Company, or MFSC), an affiliate of The Chase Manhattan
Bank, serves as transfer agent and provides fund accounting and other services
pursuant to a sub- administration agreement.






For the fiscal years ended September 30, 1994, 1995 and 1996, the Fund paid the
following administrative fees:

                              DISTRIBUTOR FOR FUND

MAS Fund Distribution, Inc. (the "Distributor"), a wholly-owned subsidiary of
the Adviser, with its principal office at One Tower Bridge, West Conshohocken,
Pennsylvania 19428, distributes the shares of the Fund. Under the Distribution
Agreement, the Distributor, as agent of the Fund, agrees to use its best efforts
as sole distributor of the Fund's shares. The Distribution Agreement which
continues in effect so long as such continuance is approved at least annually by
the Fund's Board of Trustees, including a majority of those Trustees who are not
parties to such Distribution Agreement nor interested persons of any such party.
The Distribution Agreement provides that the Fund will bear the costs of the
registration of its shares with the SEC and various states and the printing of
its prospectuses, statements of additional information and reports to
shareholders.

                                   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 of the Fund as required by the 1940 Act.



                                       31
<PAGE>

Morgan Stanley Trust Company is an affiliated person, as defined in the 1940
Act, of the Adviser and is compensated for its services as custodian on a per
account basis plus out of pocket expenses.

                             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 so doing, the Adviser will consider all matters it deems
relevant, including the following: the Adviser's knowledge of negotiated
commission rates and spreads currently available; the nature of the security or
instrument being traded; the size and type of the transaction; the nature and
character of the markets for the security or instrument to be purchased or sold;
the desired timing of the transaction; the activity existing and expected in the
market for the particular security or instrument; confidentiality; the
execution, clearance, and settlement capabilities of the broker or dealer
selected and other brokers or dealers considered; the reputation and perceived
soundness of the broker or dealer selected and other brokers or dealers
considered; the Adviser's knowledge of any actual or apparent operational
problems of a broker or dealer; and the reasonableness of the commission or its
equivalent for the specific transaction.

Although the Adviser generally seeks competitive commission rates and dealer
spreads, a Portfolio will not necessarily pay the lowest available commission on
brokerage transactions or markups on principal transactions. Transactions may
involve specialized services on the part of the broker or dealer involved, and
thereby justify higher commissions or markups than would be the case with other
transactions requiring more routine services. In addition, a Portfolio may pay
higher commission rates than the lowest available when the Adviser believes it
is reasonable to do so in light of the value of the research, statistical,
pricing, and execution services provided by the broker effecting the
transaction. The Adviser does not attempt to put a specific dollar value on the
research services rendered or to allocate the relative costs or benefits of
those services among its clients, believing that the research it receives will
help the Adviser to fulfill its overall duty to its clients. The Adviser uses
research services obtained in this manner for the benefit of all of its clients,
though each particular research service may not be used to service each client.
As a result, the Fund may pay brokerage commissions that are used, in part, to
purchase research services that are not used to benefit the Fund.

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. During the fiscal years
ended September 30, 1994, 1995 and 1996, the Fund paid brokerage commissions of
$8,785,671, $13,457,075 and $18,252,335 respectively.

Some securities considered for investment by each of the Fund's Portfolios may
also be appropriate for other clients served by the Adviser. If purchases or
sales of securities consistent with the investment policies of a Portfolio and
one or more of these other clients serviced 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.


On January 3, 1996, affiliates of Morgan Stanley Group Inc. acquired the
Adviser. As a result of this transaction, the Adviser became affiliated with
certain U.S.-registered broker-dealers and foreign broker-dealers, including
Morgan Stanley & Co. Incorporated, Morgan Stanley & Co. International Limited,
Morgan Stanley Securities Ltd., Morgan Stanley Japan Ltd., and Morgan Stanley
Asia Ltd. (collectively, "Morgan Stanley"). The Adviser may, in the exercise of
its discretion under its investment management agreement, effect transactions in
securities or other instruments for the Fund through Morgan Stanley. The Fund
paid $453,834 in brokerage commissions to affiliates for $191,758,624 of
brokered transactions for the fiscal year ended September 30, 1996.

                               GENERAL INFORMATION

Description of Shares and Voting Rights

The Declaration of Trust permits the Trustees 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 is offering shares of
twenty-six Portfolios.

The shares of each Portfolio of the Fund are fully paid and non-assessable,
except as set forth below, 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. A Shareholder of a Class is entitled to one vote for each full
Class Share held (and a fractional vote for each fractional Class Share held) of
the Shareholder's name on the books of the Fund. Shareholders of a Class have
exclusive voting rights regarding any matter submitted to shareholders that
relates solely to that Class of Shares (such as a distribution plan or service
agreement relating to that Class), and separate voting rights on any other
matter submitted to



                                       33
<PAGE>

shareholders in which the interests of the shareholders of that Class differ
from the interests of holders of any other Class.

The Fund will continue without limitation of time, provided however that:

1) Subject to the majority vote of the holders of shares of any Portfolio of the
Fund outstanding, the Trustees may sell or convert the assets of such Portfolio
to another investment company in exchange for shares of such investment company,
and distribute such shares, ratably among the shareholders of such Portfolio;

2) Subject to the majority vote of shares of any Portfolio of the Fund
outstanding, the Trustees may sell and convert into money the assets of such
Portfolio and distribute such assets ratably among the shareholders of such
Portfolio; and

3) Without the approval of the shareholders of any Portfolio, unless otherwise
required by law, the Trustees may combine the assets of any two or more
Portfolios into a single Portfolio so long as such combination will not have a
material adverse effect upon the shareholders of such Portfolio.

Upon completion of the distribution of the remaining proceeds or the remaining
assets of any Portfolio as provided in paragraphs 1), 2), and 3) above, that
Portfolio shall terminate and the Trustees shall be discharged of any and all
further liabilities and duties hereunder and the right, title and interest of
all parties shall be canceled and discharged with regard to that Portfolio.

Dividend and Capital Gains Distributions

The Fund's policy is to distribute substantially all of each Portfolio's net
investment income, if any, together with any net realized capital gains in the
amount and at the times that will avoid both income (including capital gains)
taxes on it and the imposition of the federal excise tax on undistributed income
and capital gains (see discussion under "Dividends, Capital Gains Distributions
and Taxes" in the Prospectus). The amounts of any income dividends or capital
gains distributions cannot be predicted.

Any dividend or distribution paid shortly after the purchase of shares of a
Portfolio by an investor may have the effect of reducing the per share net asset
value of that Portfolio by the per share amount of the dividend or distribution,
except for the Cash Reserves Portfolio. Furthermore, such dividends or
distributions, although in effect a return of capital, are subject to income
taxes as set forth in the Prospectus.

As set forth in the Prospectus, unless the shareholder elects otherwise in
writing, all dividends and capital gain distributions are automatically received
in additional shares of that Portfolio of the Fund at net asset value (as of the
business day following the record date). This will remain in effect until the
Fund is notified by the shareholder in writing at least three days prior to the
record date that either the Income Option (income dividends in cash and capital
gains distributions in additional shares at net asset value) or the Cash Option
(both income dividends and capital gain distributions in cash) has been elected.
An account statement is sent to shareholders whenever an income dividend or
capital gain distribution is paid.

Each Portfolio of the Fund is treated as a separate entity (and hence, as a
separate "regulated investment company") for federal tax purposes. Any net
capital gains recognized by a Portfolio are distributed to its investors without
need to offset (for federal income tax purposes) such gains against any net
capital losses of another Portfolio.

Shareholder and Trustee Liability

Under Pennsylvania law, shareholders of a trust such as the Fund may, under
certain circumstances, be held personally liable as partners for the obligations
of the trust. The Fund's Declaration of Trust contains an express disclaimer of
shareholder liability for acts or obligations of the Fund and requires that
notice of such disclaimer be given in each agreement, obligation, or instrument
entered into or executed by the Fund or the Trustees, but this disclaimer may
not be effective in some jurisdictions or as to certain types of claims. The
Declaration of Trust further provides for indemnification out of the Funds
property of any shareholder held personally liable for the obligations of the
Fund. The Declaration of Trust also provides that the Fund shall, upon request,
assume the defense of any claim made against any shareholder for any act or
obligation of the Fund and satisfy any judgment thereon. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which the Fund itself would be unable to meet its
obligations.

Pursuant to the Declaration of Trust, the Trustees may also authorize the
creation of additional series of shares (the proceeds of which would be invested
in separate, independently managed Portfolios with distinct investment
objectives and policies and share purchase, redemption and net asset valuation
procedures) with such preferences, privileges, limitations and voting and
dividend rights as the Trustees may determine. All consideration received by the
Fund for shares of any additional series or class, and all assets in which such
consideration is invested, would belong to that series or class (subject only to
the rights of creditors of the Fund) and would be subject to the liabilities
related thereto. Pursuant to the 1940 Act, as amended, shareholders of any
additional series or class of shares would normally have to approve the adoption
of any advisory contract relating to such series or class and of any changes in
the investment policies relating thereto.

The Declaration of Trust further provides that the Trustees will not be liable
for errors of judgment or mistakes of fact or law, but nothing in the
Declaration of Trust protects a Trustee against any liability to which he would
otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence, or reckless disregard of the duties involved in the conduct of the
office.

                             PERFORMANCE INFORMATION

The Fund may from time to time quote various performance figures to illustrate
the past performance of its Portfolios. Performance quotations by investment
companies are subject to rules adopted by the Securities and Exchange Commission
("SEC"), which require the use of standardized performance quotations or,
alternatively, that every non- standardized performance quotation furnished by
the Fund be accompanied by certain standardized performance information computed
as required by the SEC. An explanation of the methods for computing performance
follows.

Total Return

A Portfolio's average annual total return is determined by finding the average
annual compounded rates of return over 1, 5, and 10 year periods (or, if
shorter, the period since inception of the Portfolio) that would equate an
initial hypothetical $1,000 investment to its ending redeemable value. The
calculation assumes that all dividends and distributions are reinvested when
paid. The quotation assumes the amount was completely redeemed at the end of
each 1, 5, and 10 year period (or, if shorter, the period since inception of the
Portfolio) and the deduction of all applicable Fund expenses on an annual basis.
Average annual total return is calculated according to the following formula:



                                       35
<PAGE>

                P (1+T)n = ERV
Where:          P = a hypothetical initial payment of $1,000
                T = average annual total return
                n = number of years
                ERV = ending redeemable value of a hypothetical $1,000 payment
                      made at the beginning of the stated period

The average annual total return of each Institutional Class Portfolio of the
Fund for the periods noted is set forth below:

* The above performance information relates solely to the Institutional Class.
Performance for the Investment Class and Adviser Class would be lower because of
the Shareholder Servicing fees and 12b-1 fees charged to the Investment Class
and Adviser Class, respectively. ** The Growth and Balanced Plus Portfolios had
not commenced operations as of September 30, 1996.


The Portfolios may also calculate a total return gross of all expenses which
reflects the cumulative percentage change in value over the measuring period
prior to the deduction of all fund expenses. The formula for calculating the
total return gross of all expenses can be expressed as follows:

Total Return Gross of all Expenses = ((ERV + E)/P) -1)


                                       37

E = Fund expenses deducted from the ending redeemable value during the measuring
period.

The Municipal Portfolio and the PA Municipal Portfolio may also calculate a
total return which reflects the cumulative percentage change in value over the
measuring period after the deduction of income taxes. The formula for
calculating the total after tax return can be expressed as follows:

Total After Tax Return = (((((ERV-M)/P) x T) + (M/P)) -1)
M = Portion of ending redeemable value which was derived from tax exempt income.
T = Applicable tax rate.








The after tax returns are as follows for the Municipal Portfolio and the PA
Municipal Portfolio for the period 10/1/92 (inception of the Funds) through
9/30/96:

The tax rates used were 31% federal and 2.8% Pennsylvania. All Municipal
Interest was considered exempt from federal taxes and interest from treasuries
was considered exempt from Pennsylvania.

Yield

In addition to total return, each portfolio of the Fund (except the Cash
Reserves Portfolio) may quote performance in terms of a 30-day yield. The yield
figures provided will be calculated according to a formula prescribed by the
Securities and Exchange Commission and can be expressed as follows:


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



Where:
a =      dividends and interest earned during the period.
b =      expenses accrued for the period (net of reimbursements).
c =      the average daily number of shares outstanding during the
         period that were entitled to receive dividends.
d =      the maximum offering price per share on the last day of the
         period.

For the purpose of determining the interest earned (variable "a" in the formula)
on debt obligations that were purchased by a Portfolio at a discount or premium,
the formula generally calls for amortization of the discount or premium; the
amortization schedule will be adjusted monthly to reflect changes in the market
value of the debt obligations. The 30-day yield figures for each of the Fund's
fixed-income and equity portfolios is set forth below:


                                                                 Period ending

Yield of the Cash Reserves Portfolio

The current yield of the Cash Reserves Portfolio is calculated daily on a base
period return of a hypothetical account having a beginning balance of one share
for a particular period of time (generally 7 days). The return is determined by
dividing the net change (exclusive of any capital changes) in such account by
the value of the account at the beginning of the period and then multiplying it
by 365/7 to get the annualized current yield. The calculation of net change
reflects the value of additional shares purchased with the dividends by the
Portfolio, including dividends on both the original share and on such additional
shares. An effective yield, which reflects the effects of compounding and
represents an annualizing of the current yield with all dividends reinvested,
may also be calculated for the Portfolio by dividing the base period return by
7, adding 1 to the quotient, raising the sum to the 365th power, and subtracting
1 from the results.

Set forth below is an example, for purposes of illustration only, of the current
and effective yield calculations for the Cash Reserves Portfolio for the 7 day
base period ending September 30, 1996.

Value at beginning of period                               1.000000
Value at end of period                                     1.000992

Annualized current yield                                   5.17%
Effective yield                                            5.31%


The net asset value of the Cash Reserves Portfolio is $1.00 and has remained at
that amount since the initial offering of the Portfolio. The yield of the
Portfolio will fluctuate. The annualizing of a week's dividend is not a
representation by the Portfolio as to what an investment in the Portfolio will
actually yield in the future. Actual yields will depend on such variables as
investment quality, average maturity, the type of instruments the Portfolio
invests in, changes in interest rates on instruments, changes in the expenses of
the Fund and other factors. Yields are one basis investors may use to analyze
the Portfolios of the Fund and other investment vehicles; however, yields of
other investment vehicles may not be comparable because of the factors set forth
in the preceding sentence, differences in the time periods compared and
differences in the methods used in valuing portfolio instruments, computing net
asset value and calculating yield.

The performance of a Portfolio, as well as the composite performance of all
Fixed-Income Portfolios and all Equity Portfolios, may be compared to data
prepared by Lipper Analytical Services, Inc., CDA Investment Technologies, Inc.,
Morningstar, Inc., the Donoghue Organization, Inc. or other independent services
which monitor the performance of investment companies, and may be quoted in
advertising in terms of their rankings in each applicable universe. In addition,
the Fund may use performance data reported in financial and industry
publications, including Barron's, Business Week, Forbes, Fortune, Investor's
Daily, IBC/Donoghue's Money Fund Report, Money Magazine, The Wall Street Journal
and USA Today.

The S&P Mid Cap 400 Index consists of 400 domestic stocks chosen for market 
size, liquidity, and industry group representation. It is also a market-value
weighted index and was the first benchmark of midcap stock price movement.


S&P/BARRA Mid Cap 400 Growth Index

The S&P/BARRA Mid Cap 400 Growth Index is constructed by dividing the stocks in
the S&P MidCap 400 Index according to a single attribute: price-to-book ratios.
The MidCap 400 Growth Index is composed of firms with higher price-to-book
ratios. Like the MidCap 400, the MidCap 400 Growth Index is
capitalization-weighted, meaning that each stock is weighted in the appropriate
index in proportion to its market value.

S&P 500 Ex South Africa Index

The S&P 500 Ex South Africa Index is the same as the S&P 500 Index excluding
companies that are on the Investor Responsibility Research Center (IRRC) list of
companies doing business in South Africa. This index is maintained by Wilshire
Associates.

Wilshire 5000 Equity Index

                 APPENDIX-DESCRIPTION OF SECURITIES AND RATINGS

I. Description of Bond Ratings

Excerpts from Moody's Investors Service, Inc.'s Corporate Bond Ratings:

Aaa: judged to be the best quality; carry the smallest degree of investment
risk; Aa--judged to be of high quality by all standards; A: possess many
favorable investment attributes and are to be considered as higher medium grade
obligations; Baa: considered as lower medium grade obligations, i.e., they are
neither highly protected nor poorly secured; Ba: B: protection of interest and
principal payments is questionable.

Caa: Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest. Ca: Bonds which are rated Ca represent obligations which are
speculative in a high degree. Such issues are often in default or have other
marked shortcomings. C: Bonds which are rated C are lowest rated class of bonds
and issues so rated can be regarded as having extremely poor prospects of ever
attaining any real investment standing.

Note: Moody's may apply numerical modifiers, 1,2 and 3 in each generic rating
classification from Aa through B in its corporate bond rating system. The
modifier 1 indicates that the security ranks in the higher end of its generic
rating category; the modifier 2 indicates a mid-range ranking; and the modifier
3 indicates that the issue ranks in the lower end of its generic rating
category.

Excerpts from Standard & Poor's Corporation's Corporate Bond Ratings:

AAA: highest grade obligations; possess the ultimate degree of protection as to
principal and interest; AA: also qualify as high grade obligations, and in the
majority of instances differs from AAA issues only in small degree; A: regarded
as upper medium grade; have considerable investment strength but are not
entirely free from adverse effects of changes in economic and trade conditions.
Interest and principal are regarded as safe; BBB: regarded as borderline between
definitely sound obligations and those where the speculative element begins to
predominate; this group is the lowest which qualifies for commercial bank
investments.

BB, B, CCC, CC, C: Debt rated BB, B, CCC, CC and C is regarded, on balance, as
predominantly speculative with respect to capacity to pay interest and repay
principal in accordance with the terms of the obligation. BB indicates the
lowest degree of speculation and C the highest degree of speculation. While such
debt will likely have some quality and protective characteristics, these are
outweighed by large uncertainties or major risk exposures to adverse conditions.
CI: The rating CI is reserved for income bonds on which no interest is being
paid. D: Debt rated D is in payment default. The D rating category is used when
interest payments or principal payments are not made on the date due even if the
applicable grace period has not expired, unless S&P's believes that such
payments will be made during such grace period. The D rating also will be used
upon the filing of a bankruptcy petition if debt service payments are
jeopardized.

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

                                       46

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

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

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

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

BB: Bonds are considered speculative. The obligor's ability to pay interest and
repay principal may be affected over time by adverse economic changes. However,
business and financial alternatives can be identified which could assist the
obligor in satisfying its debt service requirements.

B: Bonds are considered highly speculative. While bonds in this class are
currently meeting debt service requirements, the probability of continued timely
payment of principal and interest reflects the obligor's limited margin of
safety and the need for reasonable business and economic activity throughout the
life of the issue.

CCC: Bonds have certain identifiable characteristics which, if not remedied, may
lead to default. The ability to meet obligations requires an advantageous
business and economic environment.

CC: Bonds are minimally protected. Default in payment of interest and/or
principal seems probable over time.

C: Bonds are in imminent default in payment of interest or principal.

DDD, DD, and D: Bonds are in default on interest and/or principal payments. Such
bonds are extremely speculative and should be valued on the basis of their
ultimate recovery value in liquidation or reorganization of the obligor. "DDD"
represents the highest potential for recovery on the these bonds, and "D"
represents the lowest potential for recovery.

Plus (+) Minus(-) Plus and minus signs are used with a rating symbol to indicate
the relative position of a credit within the rating category. Plus and minus
signs, however, are not used in the "DDD", "DD", or "D" categories.

Excerpts from Duff & Phelps Corporate Bond Ratings:

AAA: Highest credit quality. The risk factors are negligible, being only
slightly more than for risk-free U.S. Treasury debt.

AA+, AA, AA-: High credit quality. Protection factors are strong. Risk is modest
but may vary slightly from time to time of economic conditions.

A+, A, A-: Protection factors are average but adequate. However, risk factors
are more variable and greater in periods of economic stress.



                                       47

BBB+,BBB, BBB-: Below average protection factors but still considered sufficient
for prudent investment. Considerable variability in risk during economic cycles.

BB+, BB, BB-: Below investment grade but deemed likely to meet obligations when
due. Present or prospective financial protection factors fluctuate according to
industry conditions or company fortunes. Overall quality may move up or down
frequently within this category.

B+, B, B-: Below investment grade and possessing risk that obligations will not
be met when due. Financial protection factors will fluctuate widely according to
economic cycles, industry conditions and/or company fortunes. Potential exists
for frequent changes in the rating within this category or into a higher or
lower rating grade.

CCC: Well below investment grade securities. Considerable uncertainty exists as
to timely payment of principal, interest or preferred dividends. Protections
factors are narrow and risk can be substantial with unfavorable
economic/industry conditions, and/or with unfavorable company developments.

DD: Defaulted debt obligations. Issuer failed to meet scheduled principal and/or
interest payments.

DP: Preferred stock with dividend arrearage.

Description of Bond Ratings

Excerpts from Moody's Investors Service, Inc.'s Preferred Stock Ratings

aaa: An issue which is rated aaa is considered to be a top-quality preferred
stock. This rating indicates good asset protection and the least risk of
dividend impairment within the universe of preferred stocks. aa: An issue which
is rated aa is considered a high-grade preferred stock. This rating indicates
that there is reasonable assurance that earnings and asset protection will
remain relatively well maintained in the foreseeable future. a: An issue which
is rated a is considered to be an upper medium grade preferred stock. While
risks are judged to be somewhat greater than in the aaa and aa classifications,
earnings and asset protection are, nevertheless expected to be maintained at
adequate levels. baa: An issue which is rated baa is considered to be medium
grade, neither highly protected nor poorly secured. Earnings and asset
protection appear adequate at present but may be questionable over any great
length of time. ba: an issue which is rated ba is considered to have speculative
elements and its future cannot be considered well assured. Earnings and asset
protection may be very moderate and not well safeguarded during adverse periods.
Uncertainty of position characterizes preferred stocks in this class. b: An
issue which is rated b generally lacks the characteristics of a desirable
investment. Assurance of dividend payments and maintenance of other terms of the
issue over any long period of time may be small. caa: An issue which is rated
caa is likely to be in arrears on dividend payments. This rating designation
does not purport to indicate the future status of payment. ca: An issue which is
rated ca is speculative in a high degree an is likely to be in arrears on
dividends with little likelihood of eventual payment. c: This is the lowest
rated class of preferred of preference stock. Issues so rated can be regarded as
having extremely poor prospects of ever attaining any real investment standing.

Note: Moody's may apply numerical modifiers 1,2 and 3 in each rating
classification from "aa "through "b" in its preferred stock rating system. The
modifier 1 indicated that the security ranks in the higher end of its generic
rating category; the modifier 2 indicates a mid-range raking; and the modifier 3
indicates that the issue ranks in the lower end of its generic rating category.

Excerpts from Standard & Poor's Corporation's Preferred Stock Ratings

AAA: This is the highest rating that may be assigned by S&P's to a preferred
stock issue and indicates an extremely strong capacity to pay the preferred
stock obligations. AA: A preferred stock issue rated AA also qualifies as a high
quality fixed income security. The capacity to pay preferred stock obligations
is very strong, although not as





                                       48
<PAGE>

overwhelming as for issues rated AAA. A: An issue rated A is backed by a sound
capacity to pay the preferred stock obligations , although it is somewhat more
susceptible to the adverse effect of the changes in circumstances and economic
conditions. BBB: An issue rated BBB is regarded as backed by an adequate
obligations. Whereas it normally exhibits adequate protection parameter, adverse
economic conditions or changing circumstances are more likely to lead to a
weakened capacity to make payments for a preferred stock in this category than
for issues in the A category. BB,B,CCC: Preferred stock rated BB, B, and CCC are
regarded, on balance, as predominantly speculative with respect to the issuer's
capacity to pay preferred stock obligations. Bb indicates the lowest degree of
speculation and CCC the highest degree of speculation. While such issues will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties of major risk exposures to adverse conditions. CC: The
rating CC is reserved for a preferred stock in arrears on dividends or sinking
fund payments but that is currently paying. C: A preferred stock rated C is a
non-paying issue. D: A preferred stock rated D is a non-paying issue with the
issuer in default on debt instruments.

Plus(+) or Minus(-): The ratings from "AA" for "B" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.

Excerpts from Fitch Investors Services, Inc. Preferred Stock Ratings:

AAA: Preferred stocks assigned this rating are the highest quality. Strong asset
protection, conservative balance sheet ratios, and positive indications of
continued protection of preferred dividend requirements are prerequisites for an
"AAA" rating.

AA: Preferred of preference issues assigned this rating are good quality. Asset
protection and coverages of preferred dividends are considered adequate and are
expected to be maintained.

A: Preferred of preference issues assigned this rating are good quality. Asset
protection and coverages of preferred dividends are considered adequate and are
expected to be maintained.

BBB: Preferred or preference issues assigned this rating are reasonably safe but
lack the protections of the "A" to "AAA" categories. Current results should be
watched for possible of deterioration.

BB: Preferred or preference issues assigned this rating are considered
speculative. The margin of protection is slim or subject to wide fluctuations.
The loner-term financial capacities of the enterprises cannot be predicted with
assurance.

B: Issues assigned this rating are considered highly speculative. While earnings
should normally cover dividends, directors may reduce or omit payment due to
unfavorable developments, inability to finance, or wide fluctuations in
earnings.

CCC: Issues assigned this rating are extremely speculative and should be
assessed on their prospects in a possible reorganization. Dividend payments may
be in arrears with the status of the current dividend uncertain.

CC: Dividends are not currently being paid and may be in arrears. The outlook
for future payments cannot be assured.

C: Dividends are not currently being paid and may be in arrears. Prospects for
future payments are remote.

D: Issuer is in default on its debt obligations and has filed for reorganization
or liquidation under the bankruptcy law.

Plus (+) Minus (-) Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the "AAA", "CCC", "CC", "C", and "D"
categories.
