                                   JULY __, 1998
    
   
     Barr Rosenberg Series Trust (the "Trust") is an open-end management 
investment company offering five diversified portfolios with different 
investment objectives and strategies including the Barr Rosenberg Market 
Neutral Fund and Barr Rosenberg Double Alpha Market Fund.  The other 
portfolios of the Trust, which are offered under a separate prospectus, are 
the U.S. Small Capitalization Series, Japan Series and International Small 
Capitalization Series.  The Barr Rosenberg Market Neutral Fund and Barr 
Rosenberg Double Alpha Market Fund are referred to herein individually as a 
"Series" or a "Fund" and collectively as the "Series" or the "Funds."  Each 
Fund's investment manager is Rosenberg Institutional Equity Management (the 
"Manager").
    
     The BARR ROSENBERG MARKET NEUTRAL FUND seeks long-term capital 
appreciation while maintaining minimal exposure to general equity market risk 
by taking long positions in stocks principally traded in the markets of the 
United States that the Manager has identified as undervalued and short 
positions in such stocks that the Manager has identified as overvalued.  For 
a description of the risks of an investment in the Fund, see "Investment 
Objectives and Policies -- Barr Rosenberg Market Neutral Fund" and "General 
Description of Risks and Fund Investments".  The Fund seeks a total return 
greater than the return on 3-month U.S. Treasury Bills.  For a description of 
the differences between an investment in the Fund and in 3-month U.S. 
Treasury Bills, see "Investment Objectives and Policies-- Barr Rosenberg 
Market Neutral Fund."

     The BARR ROSENBERG DOUBLE ALPHA MARKET FUND seeks a total return greater 
than that of the Standard & Poor's 500 Composite Stock Price Index (the "S&P 
500 Index") by investing in shares of the Barr Rosenberg Market Neutral Fund 
while simultaneously utilizing S&P 500 Index Futures, options on S&P 500 
Index Futures and equity swap contracts to gain exposure to the equity market 
as measured by the S&P 500 Index.  See "Investment Objectives and Policies -- 
Barr Rosenberg Double Alpha Market Fund" and "General Description of Risks 
and Fund Investments."
   
     The Funds offer two classes of shares: Institutional Shares and Investor 
Shares.  Whether an investor is eligible to purchase Institutional or 
Investor Shares generally depends on the amount invested in a particular 
Fund.  Investor Shares bear a Shareholder Service Fee and Distribution Fee.
    
     This Prospectus concisely describes the information that investors ought 
to know before investing.  Please read this Prospectus carefully and keep it 
for future reference.
   
     A Statement of Additional Information dated July __, 1998 (the 
"Statement") is available free of charge by writing to Barr Rosenberg Funds

     The Manager has undertaken to reduce its management fee and bear certain 
expenses until further notice in order to limit the total annual operating 
expenses (which do not include nonrecurring account fees and extraordinary 
expenses) of each class to the percentage of a Fund's total annual operating 
expenses attributable to that class listed under Total Fund Operating 
Expenses above.  Absent such undertaking by the Manager to waive its fee and 
bear such expenses, the Barr Rosenberg Market Neutral Fund's management fees 
would be 1.90% and estimated Total Fund Operating Expenses would be 2.33% for 
Institutional Shares and 2.83% for Investor Shares, and the Barr Rosenberg 
Double Alpha Market Fund's management fees would be 0.10%, estimated Other 
Expenses (including indirect expenses) would be 2.88% and estimated Total 
Fund Operating Expenses (including indirect expenses) would be 2.98% for 
Institutional Shares and 3.48% for Investor Shares.  See "Management of the 
Trust."

__________
*    Includes, in the case of the Barr Rosenberg Double Alpha Market Fund,
     indirect expenses borne through ownership of Institutional Shares of the
     Barr Rosenberg Market Neutral Fund.

     Each Fund's investment performance may from time to time be included in 
advertisements about such Fund.  Total return for a Fund is measured by 
comparing the value of an investment in such Fund at the beginning of the 
relevant period to the redemption value of the investment in such Fund at the 
end of such period (assuming immediate reinvestment of any dividends or 
capital gains distributions).  All data are based on a Fund's past investment 
results and do not predict future performance.  Investment performance, which 
will vary, is based on many factors, including market conditions, the 
composition of a Fund's portfolio and a Fund's operating expenses.  
Investment performance also often reflects the risks associated with a Fund's 
investment objective and policies.  These factors should be considered when 
comparing a Fund's investment results with those of other mutual funds and 
other investment vehicles. Quotations of investment performance for any 
period when an expense limitation was in effect will be greater than if the 
limitation had not been in effect.
    
                         INVESTMENT OBJECTIVES AND POLICIES
                                          
BARR ROSENBERG MARKET NEUTRAL FUND

     The investment objective of the Barr Rosenberg Market Neutral Fund is to 
seek long-term capital appreciation while maintaining minimal exposure to 
general equity market risk.  The Fund seeks a total return greater than the 
return on 3-month U.S. Treasury Bills.  The Fund attempts to achieve its 
objective by taking long positions in stocks principally traded in the 
markets of the United States that the Manager has identified as undervalued 
and short

                                      -6-

<PAGE>
   
positions in such stocks that the Manager has identified as overvalued.  See 
"General Description of Risks and Fund Investments -- Risks of Short Sales" 
below.  By taking long and short positions in different stocks with similar 
characteristics, the Fund attempts to cancel out the effect of general stock 
market movements on the Fund's performance.  The Manager will determine the 
size of each long or short position by analyzing the tradeoff between the 
attractiveness of each position and its impact on the risk of the overall 
portfolio.  The Fund seeks to construct a diversified portfolio that has 
minimal net exposure to the U.S. equity market generally and near neutral 
exposure to specific industries, specific capitalization ranges and certain 
other risk factors.  The Manager currently expects that the long and short 
positions of the Fund will be invested primarily in small capitalization 
stocks and smaller mid-capitalization stocks.  For purposes of the preceeding 
sentence, the 200 stocks principally traded in U.S. markets with the largest 
market capitalizations are considered large capitalization stocks, the next 
800 largest are considered mid-capitalization stocks and all others are 
considered small capitalization stocks.
    
   
     Although the Fund's investment strategy seeks to minimize the risk 
associated with investing in the equity market, an investment in the Fund 
will be subject to the risk of poor stock selection by the Manager.  For 
example, the Manager may not be successful in executing its strategy of 
taking long positions in stocks and short positions in other stocks, such 
that the portfolio of long positions outperforms the portfolio of short 
positions.  In addition, the Manager may fail to construct a portfolio that 
has minimal exposure to general equity market risk or that has near neutral 
exposure to specific industries, specific capitalization ranges and certain 
other risk factors.  Further, since the Manager will manage both a long and a 
short portfolio, an investment in the Fund will involve the risk that the 
Manager may make more poor investment decisions than a manager of a typical 
stock mutual fund with only a long portfolio.  An investment in 3-month U.S. 
Treasury Bills is different from an investment in the Fund because Treasury 
Bills are backed by the full faith and credit of the U.S. Government, 
Treasury Bills have a fixed rate of return and investors in Treasury Bills do 
not bear the risk of losing their investment.
    
     To meet margin requirements, redemptions or pending investments, the 
Fund may also temporarily hold a portion of its assets in full faith and 
credit obligations of the United States government (E.G., U.S. Treasury 
Bills) and in short-term notes, commercial paper or other money market 
instruments of high quality (I.E., rated at least "A-2" or "AA" by Standard & 
Poor's ("S&P") or Prime 2 or "Aa" by Moody's Investors Service, Inc. 
("Moody's")) issued by companies having an outstanding debt issue rated at 
least "AA" by S&P or at least "Aa" by Moody's, or determined by the Manager 
to be of comparable quality to any of the foregoing.

     The Fund's long and short positions may involve (without limit) equity 
securities of foreign issuers that are principally traded in the markets of 
the United States.  See "General Description of Risks and Fund Investments 
- --Special Considerations of Foreign Investments."  The Fund will not invest 
in equity securities that are principally traded outside of the United States.

BARR ROSENBERG DOUBLE ALPHA MARKET FUND

     The investment objective of the Barr Rosenberg Double Alpha Market Fund 
is to seek a total return greater than that of the Standard & Poor's 500 
Composite Stock Price Index (the "S&P 500 Index").  The Fund seeks to achieve 
its objective by investing in shares of the Barr Rosenberg Market Neutral 
Fund while simultaneously utilizing S&P 500 Index Futures, options on S&P 500 
Index Futures and equity swap contracts to gain exposure to the equity market 
as measured by the S&P 500 Index.  See "Investment Objectives and Policies -- 
Barr Rosenberg Market Neutral Fund" and "General Description of Risks and 
Fund Investments --Risks of S&P 500 Index Futures and Related Options" and 
"-- Equity Swap Contracts" below.  The Fund has applied to the Securities and 
Exchange Commission for an exemptive order allowing it to invest without 
limit in the Barr Rosenberg Market Neutral Fund.  Once the Fund has 
indirectly constructed a diversified long and short portfolio through the 
purchase of shares of the Barr Rosenberg Market Neutral Fund, the Manager 
will purchase S&P 500 Index Futures, options on S&P 500 Index Futures and 
equity swap contracts in an amount approximately equal to the net asset value 
of the Fund in order to gain full net exposure to the U.S. equity market as 
measured by the S&P 500 Index.  In addition to purchasing shares of the Barr 
Rosenberg Market Neutral Fund, the Fund may also take long positions in 
stocks principally traded in the markets

                                      -7-

<PAGE>

of the United States that the Manager has identified as undervalued and short 
positions in such stocks that the Manager has identified as overvalued.  See 
"General Description of Risks and Fund Investments -- Risks of Short Sales."

     The S&P 500 Index is an unmanaged index composed of 500 common stocks, 
most of which are listed on the New York Stock Exchange.  The S&P 500 Index 
assigns relative values to the stocks included in the index, weighted 
according to each stock's total market value relative to the total market 
value of the other stocks included in such index.
   
     To meet margin requirements, redemptions or pending investments, the 
Fund may also temporarily hold a portion of its assets in full faith and 
credit obligations of the United States government (e.g., U.S. Treasury 
Bills) and in short-term notes, commercial paper or other money market 
instruments of high quality (i.e., rated at least "A-2" or "AA" by S&P or 
Prime 2 or "Aa" by Moody's) issued by companies having an outstanding debt 
issue rated at least "AA" by S&P or at least "Aa" by Moody's, or determined 
by the Manager to be of comparable quality to any of the foregoing.
    
     The Fund's long and short positions may involve (without limit) equity 
securities of foreign issuers that are principally traded in the markets of 
the United States.  See "General Description of Risks and Fund Investments 
- --Special Considerations of Foreign Investments."  The Fund will not invest 
in equity securities that are principally traded outside of the United States.

     In a typical stock mutual fund the portfolio manager attempts to earn an 
excess return (return above market return) or "alpha" by identifying and 
purchasing UNDERVALUED stocks.  However, there is another "alpha" possibility 
- --identifying and selling short OVERVALUED stocks.  The term "double alpha" 
refers to the fact that there are thus two potential sources of alpha: one 
from correctly identifying undervalued stocks and one from correctly 
identifying overvalued stocks.  The market neutral strategy employed by both 
the Barr Rosenberg Market Neutral Fund and indirectly by the Barr Rosenberg 
Double Alpha Market Fund (through investment in shares of the Barr Rosenberg 
Market Neutral Fund) seeks to capture both alphas.  The Barr Rosenberg Double 
Alpha Market Fund also seeks gain (and incurs additional risk) by investing 
in S&P 500 Index instruments.

INVESTMENT CONSIDERATIONS

     An investor desiring capital appreciation with minimal exposure to the 
equity market may wish to consider the Barr Rosenberg Market Neutral Fund.  
An investor desiring enhanced equity market returns exceeding the return on 
the S&P 500 Index may wish to consider the Barr Rosenberg Double Alpha Market 
Fund.

                 GENERAL DESCRIPTION OF RISKS AND FUND INVESTMENTS
   
     INVESTMENT RISKS.  The value of Fund shares may increase or decrease 
depending on market, economic, political, regulatory and other conditions 
affecting each Fund's portfolio.  Investment in shares of the Funds is more 
volatile and risky than some other forms of investment.  In addition, if the 
Manager takes long positions in stocks and short positions in other stocks 
such that the portfolio of long positions underperforms while the portfolio 
of short positions outperforms the market, then the losses of the Barr 
Rosenberg Market Neutral Fund and Barr Rosenberg Double Alpha Market Fund may 
exceed those of other stock mutual funds.  Moreover, the market neutral 
strategy has the effect of accelerating the recognition of gain for tax 
purposes and increasing the short-term gain component of gains in the Funds.
Short-term gains are ordinarily taxed to shareholders at ordinary income tax 
rates.
    
     RISKS OF SHORT SALES (BOTH FUNDS).  When the Manager anticipates that a 
security is overvalued, it may sell the security short and borrow the same 
security from a broker or other institution to complete the sale.  A Fund 
will incur a loss as a result of a short sale if the price of the borrowed 
security increases between the date of the short sale and the date on which 
the Fund replaces such security.  A Fund will realize a gain if the security 
declines in price between those dates.  There can be no assurance that a Fund 
will be able to close out a short position at any particular time or at an 
acceptable price. Although a Fund's gain is limited to the amount at which it 
sold a security short, its

                                      -8-

<PAGE>
   
potential loss is limited only by the maximum attainable price of the 
security less the price at which the security was sold.  Until a Fund 
replaces a borrowed security, it will maintain daily a segregated account 
with its Custodian containing cash, U.S. Government securities, or other 
liquid securities such that the amount deposited in the account plus any 
amount deposited with a broker or other custodian as collateral will at least 
equal the current market value of the security sold short.  Depending on 
arrangements made with such broker or custodian, a Fund may not receive any 
payments (including interest) on collateral deposited with such broker or 
custodian.  The Funds will not make a short sale if, after giving effect to 
such sale, the market value of all securities sold exceeds 100% of the value 
of a Fund's net assets.  A Fund's use of short sales may result in the Fund 
realizing more short-term capital gains (subject to tax at ordinary income 
rates) than it would if it did not engage in short sales.
    
     RISKS OF S&P 500 INDEX FUTURES AND RELATED OPTIONS (BARR ROSENBERG 
DOUBLE ALPHA MARKET FUND ONLY).  An S&P 500 Index Future contract (an "Index 
Future") is a contract to buy or sell an integral number of units of the S&P 
500 Index at a specified future date at a price agreed upon when the contract 
is made.  A unit is the value at a given time of the S&P 500 Index.  Entering 
into a contract to buy units is commonly referred to as buying or purchasing 
a contract or holding a long position in the S&P 500 Index.  An option on an 
Index Future gives the purchaser the right, in return for the premium paid, 
to assume a long or a short position in an Index Future.  The Barr Rosenberg 
Double Alpha Market Fund will realize a loss if the value of the S&P 500 
Index declines between the time the Fund purchases an Index Future or an 
option transaction in which the Fund has assumed a long position and may 
realize a gain if the value of the S&P 500 Index rises between such dates.

     The Barr Rosenberg Double Alpha Market Fund may close out a futures 
contract purchase by entering into a futures contract sale.  This will 
operate to terminate the Fund's position in the futures contract.  Positions 
in Index Futures may be closed out by the Fund only on the futures exchanges 
on which the Index Futures are then traded.  There can be no assurance that a 
liquid market will exist for any particular contract at any particular time.  
The liquidity of the market in futures contracts could be adversely affected 
by "daily price fluctuation limits" established by the relevant futures 
exchange which limit the amount of fluctuation in the price of an Index 
Future during a single trading day.  Once the daily limit has been reached in 
the contract, no trades may be entered into at a price beyond the limit.  In 
such event, it may not be possible for the Fund to close its futures contract 
purchase, and, in the event of adverse price movements, the Fund would 
continue to be required to make daily cash payments of variation margin 
(payments to and from a broker made on a daily basis as the price of the 
Index Future fluctuates).  The futures market may also attract more 
speculators than does the securities market, because deposit requirements in 
the futures market are less onerous than margin requirements in the 
securities market.  Increased participation by speculators in the futures 
market may also cause price distortions.

     Further, when the Barr Rosenberg Double Alpha Market Fund purchases an 
Index Future, it is required to maintain, at all times while an Index Future 
is held by the Fund, cash, U.S. Government securities or other high grade 
liquid securities in a segregated account with its Custodian, in an amount 
which, together with the initial margin deposit on the futures contract, is 
equal to the current value of the futures contract.
   
     EQUITY SWAP CONTRACTS (BARR ROSENBERG DOUBLE ALPHA MARKET FUND ONLY).  
In an equity swap contract, the counterparty generally agrees to pay the Barr 
Rosenberg Double Alpha Market Fund the amount, if any, by which the notional 
amount of the equity swap contract would have increased in value had it been 
invested in the basket of stocks comprising the S&P 500 Index, plus the 
dividends that would have been received on those stocks.  The Fund agrees to 
pay to the counterparty a floating rate of interest (typically the London 
Inter Bank Offered Rate) on the notional amount of the equity swap contract 
plus the amount, if any, by which that notional amount would have decreased 
in value had it been invested in such stocks.  Therefore, the return to the 
Fund on any equity swap contract should be the gain or loss on the notional 
amount plus dividends on the stocks comprising the S&P 500 Index (as if the 
Fund had invested the notional amount in stocks comprising the S&P 500 Index) 
less the interest paid by the Fund on the notional amount.  Therefore, the 
Fund will generally realize a loss if the value of the S&P 500 Index declines 
and will generally realize a gain if the value of the S&P 500 Index rises.  
The Fund will enter into equity swap contracts only on a net basis, i.e., 
where the two parties' obligations are netted out, with the Fund paying or 
receiving,

                                      -9-
<PAGE>

as the case may be, only the net amount of any payments.  If there is a 
default by the counterparty to an equity swap contract, the Fund will be 
limited to contractual remedies pursuant to the agreements related to the 
transaction.  The Fund's use of equity swap contracts may result in the Fund 
realizing more income subject to tax at ordinary income tax rates than it 
would if it did not enter into equity swap contracts.
    
     There is no assurance that the equity swap contract counterparties will 
be able to meet their obligations or that, in the event of default, the Barr 
Rosenberg Double Alpha Market Fund will succeed in pursing contractual 
remedies. The Fund thus assumes the risk that it may be delayed in or 
prevented from obtaining payments owed to it pursuant to these contracts.  
The Fund will closely monitor the credit of equity swap contract 
counterparties in order to minimize this risk.  The Fund will not use equity 
swap contracts for leverage.

     The Barr Rosenberg Double Alpha Market Fund will not enter into any 
equity swap contract unless, at the time of entering into such transaction, 
the unsecured senior debt of the counterparty is rated at least A by Moody's 
or S&P. In addition, the staff of the Securities and Exchange Commission 
considers equity swap contracts to be illiquid securities.  Consequently, 
while the staff maintains this position, the Fund will not invest in equity 
swap contracts if, as a result of the investment, the total value of such 
investments together with that of all other illiquid securities which the 
Fund owns would exceed 15% of the Fund's net assets.

     The net amount of the excess, if any, of the Fund's obligations over its 
entitlement with respect to each equity swap contract will be accrued on a 
daily basis, and an amount of cash, U.S. Government Securities or other 
liquid securities having an aggregate market value at least equal to the 
accrued excess will be maintained in a segregated account by the Fund's 
Custodian.  The Fund does not believe that the Fund's obligations under 
equity swap contracts are senior securities, so long as such a segregated 
account is maintained, and accordingly, the Fund will not treat them as being 
subject to its borrowing restrictions.

     SPECIAL CONSIDERATIONS OF FOREIGN INVESTMENTS (BOTH FUNDS).  Investing 
in securities of foreign issuers involves certain risks not typically found 
in investing in securities of U.S. issuers.  These include risks of adverse 
change in foreign economic, political, regulatory and other conditions, and 
changes in currency exchange rates, exchange control regulations (including 
currency blockage), expropriation of assets or nationalization, imposition of 
withholding taxes on dividend or interest payments, and possible difficulty 
in obtaining and enforcing judgments against foreign entities.  Furthermore, 
issuers of foreign securities are subject to different, and often less 
comprehensive, accounting, reporting and disclosure requirements than 
domestic issuers.  In certain countries, legal remedies available to 
investors may be more limited than those available with respect to 
investments in the United States or other countries. The securities of some 
foreign issuers are less liquid and at times more volatile than securities of 
comparable U.S. issuers.  There are also special tax considerations which 
apply to securities of foreign issuers.
   
    
     REPURCHASE AGREEMENTS (BOTH FUNDS).  Each Fund may enter into repurchase 
agreements, by which a Fund purchases a security and obtains a simultaneous 
commitment from the seller (a bank or, to the extent permitted by the 
Investment Company Act of 1940, as amended (the "1940 Act"), a recognized 
securities dealer) to repurchase the security at an agreed-upon price and 
date (usually seven days or less from the date of original purchase).  The 
resale price is in excess of the purchase price and reflects an agreed-upon 
market rate unrelated to the coupon rate on the purchased security.  Such 
transactions afford the Funds the opportunity to earn a return on temporarily 
available cash.  Although the underlying security may be a bill, certificate 
of indebtedness, note or bond issued by an agency, authority or 
instrumentality of the U.S. Government, the obligation of the seller is not 
guaranteed by the U.S. Government and there is a risk that the seller may 
fail to repurchase the underlying security.  In such event, a Fund would 
attempt to exercise rights with respect to the underlying security, including 
possible disposition in the market.  However, a Fund may be subject to 
various delays and risks of loss, including (a) possible declines in the 
value of the underlying security during the period while a Fund seeks to 
enforce its rights thereto and (b) inability to enforce rights and the 
expenses involved in attempted enforcement.

     LOANS OF PORTFOLIO SECURITIES (BOTH FUNDS).  Each Fund may lend some or 
all of its portfolio securities to broker-dealers.  Securities loans are made 
to broker-dealers pursuant to agreements requiring that loans be continuously 
secured by collateral in cash or U.S. Government securities at least equal at 
all times to the market value

                                      -10-

<PAGE>

of the securities lent.  The borrower pays to the lending Fund an amount 
equal to any dividends or interest received on the securities lent.  When the 
collateral is cash, the Funds may invest the cash collateral in 
interest-bearing, short-term securities.  When the collateral is U.S. 
Government securities, the Fund usually receives a fee from the borrower. 
Although voting rights or rights to consent with respect to the loaned 
securities pass to the borrower, a Fund retains the right to call the loans 
at any time on reasonable notice, and it will do so in order that the 
securities may be voted by the Fund if the holders of such securities are 
asked to vote upon or consent to matters materially affecting the investment. 
 A Fund may also call such loans in order to sell the securities involved.  
The risks in lending portfolio securities, as with other extensions of 
credit, include possible delay in recovery of the securities or possible loss 
of rights in the collateral should the borrower fail financially.  However, 
such loans will be made only to broker-dealers that are believed by the 
Manager to be of relatively high credit standing.

     ILLIQUID SECURITIES (BOTH FUNDS).  Each Fund may purchase "illiquid 
securities", defined as securities which cannot be sold or disposed of in the 
ordinary course of business within seven days at approximately the price at 
which a Fund has valued such securities, so long as no more than 15% of a 
Fund's net assets would be invested in such illiquid securities after giving 
effect to a purchase.  Investment in illiquid securities involves the risk 
that, because of the lack of consistent market demand for such securities, a 
Fund may be forced to sell them at a discount from the last offer price.

     PORTFOLIO TURNOVER.  Portfolio turnover is not a limiting factor with 
respect to investment decisions of the Manager.  The rate of a Fund's 
portfolio turnover may vary significantly from time to time depending on the 
volatility of economic and market conditions.  Although the rate of portfolio 
turnover is difficult to predict, it is not anticipated that under normal 
circumstances the annual portfolio turnover rate of each of the long and 
short portfolios of the Barr Rosenberg Market Neutral Fund will exceed 150%, 
and it is not anticipated that under normal circumstances the annual 
portfolio turnover rate of the Barr Rosenberg Double Alpha Market Fund will 
exceed 50%.  It is, however, impossible to predict portfolio turnover in 
future years.  High portfolio turnover involves correspondingly greater 
brokerage commissions and other transaction costs, which will be borne 
directly by a Fund, and could involve realization of capital gains that would 
be taxable when distributed to shareholders of such Fund.  To the extent 
portfolio turnover results in the realization of net short-term capital 
gains, such gains ordinarily are taxed to shareholders at ordinary income tax 
rates.  See "Taxes."

     INVESTMENT OBJECTIVES AND POLICIES.  Except as explicitly described 
otherwise, the investment objective and policies of each of the Funds may be 
changed without shareholder approval.

                              PERFORMANCE INFORMATION
   
     Rosenberg Institutional Equity Management also serves as the manager of 
other accounts that have investment objectives, policies and strategies that 
are substantially similar to those of the Barr Rosenberg Market Neutral Fund 
(collectively, the "Market Neutral Accounts").  The information below should 
not be considered a prediction of the future performance of the Barr 
Rosenberg Market Neutral Fund.  The performance of such Fund may be higher or 
lower than the performance of the Market Neutral Accounts.  The performance 
information shown below is based on a composite of all of the Manager's 
accounts with substantially similar investment objectives, policies and 
strategies and has been adjusted to give effect to the estimated annualized 
expenses (without giving effect to any expense waivers or reimbursements) of 
Institutional Shares of the Barr Rosenberg Market Neutral Fund during its 
first year of operations. The Market Neutral Accounts were not registered 
under the 1940 Act and therefore were not subject to certain investment 
restrictions imposed by the 1940 Act. If the Market Neutral Accounts had been 
registered under the 1940 Act, their performance might have been adversely 
affected.  In addition, the Market Neutral Accounts were not subject to 
Subchapter M of the Internal Revenue Code.  The following table shows the 
average annual total return for the one-year, three-year, five-year and 
since-inception periods ending _______, 1998 for the Market Neutral Accounts. 
The following table also shows the average annual total return on 3-month 
U.S. Treasury bills for the same periods.

     An investment in 3-month U.S. Treasury Bills is different from an 
investment in the Barr Rosenberg Market Neutral Fund because Treasury Bills 
are backed by the full faith and credit of the U.S. Government, Treasury 
Bills have a fixed rate of return and investors in Treasury Bills do not bear 
the risk of losing their investment.  Giving effect to the expense limitation 
of 2.00% on the expenses of the Institutional Shares of the Barr Rosenberg 
Market Neutral Fund as set forth in the "Fund Expenses" section, the average 
annual total return for the one-year, three-year, five-year and 
since-inception periods ending ________, 1998 for the Market Neutral Accounts 
would have been ____%, _____%, _____% and _____%, respectively.  There have 
been two enhancements to the Manager's market neutral strategy since its 
inception in 1989.  First, the Manager incorporated its Earnings Change Model 
and Investor Sentiment Model into its market neutral strategy in October 1992 
and April 1993, respectively.  See "Management of the Trust -- The Manager's 
General Investment Philosophy and Strategy."  The second change to the 
Manager's market neutral strategy occurred in July 1995, when the Manager 
focused its strategy on medium and smaller capitalization companies.  Prior 
to such date, the Manager had applied its market neutral strategy to 
companies across the capitalization spectrum (I.E., large, medium and small 
capitalization companies).  Throughout both periods, however, the Manager has 
maintained long and short positions of approximately the same dollar amount 
within a given capitalization sector.  The Funds may invest in stocks of 
companies of any capitalization to meet risk/return objectives and liquidity 
needs.  Despite the two enhancements to the Manager's market neutral strategy 
since 1989, the Barr Rosenberg Market Neutral Fund will have substantially 
similar investment objectives, policies and strategies as the Market Neutral 
Accounts.
    
                              MANAGEMENT OF THE TRUST

     Each Fund is advised and managed by Rosenberg Institutional Equity 
Management (the "Manager") which provides investment advisory services to a 
substantial number of institutional investors.  The Manager is also the 
investment manager of the other funds of the Trust.

KEY PERSONNEL OF THE MANAGER

     The biography of each of the General Partners of the Manager, each of 
whom is also a Trustee of the Trust, is set forth below.

     BARR ROSENBERG.  Dr. Rosenberg is Managing General Partner and Chief 
Investment Officer of the Manager.  As such, he has ultimate responsibility 
for the Manager's securities valuation and portfolio optimization systems 
used to manage the Funds and for the implementation of the decisions 
developed therein. His area of special concentration is the design of the 
Manager's proprietary securities valuation model.

     Dr. Rosenberg earned a B.A. degree from the University of California, 
Berkeley, in 1963.  He earned an M.Sc. from the London School of Economics in 
1965, and a Ph.D. from Harvard University, Cambridge, Massachusetts, in 1968. 
From 1968 until 1983, Dr. Rosenberg was a Professor of Finance, Econometrics, 
and Economics at the School of Business Administration at the University of 
California, Berkeley.  Concurrently, from 1968 until 1974, Dr. Rosenberg 
worked as a consultant in applied decision theory in finance, banking and 
medicine.  In 1975, he founded Barr Rosenberg Associates, a financial 
consulting firm (now known as BARRA) where he was a managing partner, and 
later chief scientist.  Dr. Rosenberg, the founder of the Berkeley Program in 
Finance, is acknowledged as an expert in the modeling of complex processes 
with substantial elements of risk.

affiliate, Barr Rosenberg Investment Management, Inc., located in Orinda, 
California.  Included among the Manager's professional staff are seven 
individuals with Ph.D.s and eighteen individuals with other graduate degrees. 
Five members of the staff have been awarded C.F.A. certificates.

THE OUTSIDE TRUSTEES

     William F. Sharpe and Nils H. Hakansson are Trustees of the Trust who 
are not "interested persons" (as defined in the 1940 Act) of the Trust or the 
Manager.

     Dr. Sharpe is the STANCO 25 Professor of Finance at Stanford 
University's Graduate School of Business.  He is best known as one of the 
developers of the Capital Asset Pricing Model, including the beta and alpha 
concepts used in risk analysis and performance measurement.  He developed the 
widely-used binomial method for the valuation of options and other contingent 
claims.  He also developed the computer algorithm used in many asset 
allocation procedures.  Dr. Sharpe has published articles in a number of 
professional journals.  He has also written six books, including PORTFOLIO 
THEORY AND CAPITAL MARKETS, (McGraw-Hill, 1970), ASSET ALLOCATION TOOLS, 
(Scientific Press, 1987), FUNDAMENTALS OF INVESTMENTS (with Gordon J. 
Alexander and Jeffery Bailey, Prentice-Hall, 1993) and INVESTMENTS (with 
Gordon J. Alexander and Jeffery Bailey, Prentice-Hall, 1995).  Dr. Sharpe is 
a past President of the American Finance Association.  He has also served as 
consultant to a number of corporations and investment organizations.  He is

THE MANAGER'S GENERAL INVESTMENT PHILOSOPHY AND STRATEGY

     The Manager attempts to add value relative to a benchmark through a 
quantitative stock selection process, and seeks to diversify investment risk 
across the holdings in each Fund.  In seeking to outperform each Fund's 
benchmark, the Manager also attempts to control risk in a Fund's portfolio 
relative to the benchmark.

     INVESTMENT PHILOSOPHY.  The Manager's investment strategy is based on 
the belief that stock prices imperfectly reflect the present value of the 
expected future earnings of companies, their "fundamental value."  The 
Manager believes that market prices will converge towards fundamental value 
over time, and that therefore, if the Manager can accurately determine 
fundamental value, and can apply a disciplined investment process to select 
those stocks that are currently undervalued (in the case of purchases) or 
overvalued (in the case of short sales), the Manager will outperform a Fund's 
benchmark over time.

     The premise of the Manager's investment philosophy is that there is a 
link between the price of a stock and the underlying financial and 
operational characteristics of the company.  In other words, the price 
reflects the market's assessment of how well the company is positioned to 
generate future earnings and/or future cash flow.  The Manager identifies and 
purchases those stocks which are undervalued (I.E., they are currently 
cheaper than similar stocks with the same characteristics) and engages in 
short sales with respect to those stocks that are overvalued (I.E., they are 
currently more expensive than similar stocks with the same characteristics).  
The Manager believes that the market will recognize the "better value" and 
that the mispricing will be corrected as the stocks in the Fund's portfolios 
are purchased or sold by other investors.

     Determination of the relative valuation of a stock is based upon a 
comparison of similar companies.  In any group of similar companies, it is 
the Manager's view that there are always some that are overvalued, some that 
are undervalued, and some that are fairly-valued relative to the average 
valuation for the group.  These moderate valuation errors are believed to be 
present in every sector of the market and can be identified through rigorous 
quantitative analysis of fundamental data.

     In determining whether or not a stock is attractive, the Manager 
considers the company's current estimated fundamental value as determined by 
the Manager's proprietary Appraisal Model, the Manager's model for expected 
earnings, and analysis of investor sentiment toward the stock.  The Manager 
identifies and causes a Fund to purchase an undervalued stock and to hold it 
in the Fund's portfolio until the market recognizes and corrects for the 
misvaluation. Conversely, the Manager identifies and causes a Fund to sell 
short an overvalued stock.

     DECISION PROCESS.  The Manager's decision process is a continuum.  Its 
research function develops Models which analyze the approximately 12,000 
securities in the global universe, both fundamentally and technically, and 
determines the risk characteristics of the Fund's benchmark.  The portfolio 
management function optimizes each portfolio's composition, executes trades, 
and monitors performance and trading costs.

     The essence of the Manager's approach is rigorous attention to important 
aspects of the investment process.  Factors crucial to successful stock 
selection include: (1) accurate and timely data on a large universe of 
companies; (2) subtle quantitative descriptors of value and predictors of 
changes in value; and (3) insightful definitions of similar

                                      -14-

<PAGE>

businesses.  The Manager takes great care assimilating, checking and 
structuring the input data on which its Models rely.  The Manager believes 
that if the data is correct, the recommendations made by the system will be 
sound.

     STOCK SELECTION.  Fundamental valuation of stocks is key to the 
Manager's investment process, and the heart of the valuation process lies in 
the Manager's proprietary Appraisal Model.  Analysis of companies in the 
United States and Canada is conducted in a single unified Model.  The 
Appraisal Model discriminates where the two markets are substantially 
different, while simultaneously comparing companies in the two markets 
according to their degrees of similarity.  European companies and Asian 
companies (other than Japanese companies) are analyzed in a nearly global 
Model, which includes the United States and Canada as a further basis for 
comparative valuation, but which excludes Japan.  Japanese companies are 
analyzed in an independent national Model.  The Model incorporates the 
various accounting standards which apply in different markets and makes 
adjustments to ensure meaningful comparisons.

     An important feature of the Appraisal Model is the classification of 
companies into one or more of 166 groups of "similar" businesses.  Currently, 
in the United States, 160 groups are applicable; in Japan, 122 groups are 
applicable; and in Europe, 154 groups are applicable.  Each company is broken 
down into its individual business segments, and each segment is compared with 
similar business operations of other companies doing business in the same 
geographical market.  In most cases, the comparison is extended to include 
companies with similar business operations in different markets.  Subject to 
the availability of data in different markets, the Manager appraises the 
company's assets, operating earnings and sales within each business segment, 
accepting the market's valuation of that category of business as fair.  The 
Manager then integrates the segment appraisals into balance sheet, income 
statement and sales valuation models for the total company, and 
simultaneously adjusts the segment appraisals to include appraisals for 
variables which are declared only for the total company, such as taxes, 
capital structure, and pension funding.  The result is a single valuation for 
each of the approximately 12,000 companies followed.

     The difference between the Manager's appraisal and the market price is 
believed to represent an opportunity for profit.  For each stock, the Manager 
develops "appraisal alphas" (I.E., the expected rate of extraordinary return) 
by adjusting for the rate at which the market has corrected for such 
misvaluations in the past.

     A second sphere of analysis is captured by the Manager's proprietary 
Earnings Change Model, which analyzes more than 20 variables to predict 
individual company earnings over a one year horizon.  The variables are 
fundamental and fall into three categories: measures of past profitability, 
measures of company operations and consensus earnings forecasts.  The 
Earnings Change Model is independent of the Appraisal Model and projects the 
change in a company's earnings in cents/current price.  The value of the 
projected earnings change is converted to an "earnings change alpha" by 
multiplying the projected change by the market's historical response to 
changes of that magnitude.

     Finally, the Manager's proprietary Investor Sentiment Model quantifies 
investor sentiment about features of stocks which influence price but which 
are not captured by the Appraisal Model or the Earnings Change Model.  This 
Model measures company quality by looking at past price patterns and by 
predicting the probability of deficient earnings.  The Investor Sentiment 
Model also captures market enthusiasm towards individual stocks by looking at 
broker recommendations and analyst estimates.  Investor sentiment alphas are 
developed by multiplying the Model's sentiment scores by the market's 
historical response to such scores.

     Each company's earnings change alpha and investor sentiment alpha are 
added to its appraisal alpha to arrive at a total company alpha.  Stocks with 
large positive total company alphas are candidates for purchase.  Stocks with 
large negative total company alphas are candidates for short sales.  Stocks 
held in a portfolio with total company alphas that are only slightly 
positive, zero or negative are candidates for sale.

     Before trading, the Manager systematically analyzes the short-term price 
behavior of individual stocks to determine the timing of trades.  The 
Investor Sentiment Model quantifies investor enthusiasm for each stock by

analyzing its short-term performance relative to similar stocks, changes in 
analyst and broker opinions about the stock, and earnings surprises.  The 
Manager develops a "trading alpha" for each stock, which is the Manager's 
prediction of the short-term return of a particular stock.  This return is 
calculated by the Manager's proprietary model by analyzing short-term factors 
such as trading volume and price movements.  The Manager believes its model, 
used in this way, can add value by helping determine the optimal timing of 
portfolio trades.

     OPTIMIZATION.  The Manager's portfolio optimization system seeks to 
optimize the trade-off between risk and reward relative to a Fund's 
benchmark. It exploits the information developed by the Manager's stock 
selection Models to maximize return relative to the benchmark, while avoiding 
a portfolio with exposure to any other extraneous factors that would 
distinguish the Fund's portfolio from the relevant benchmark.  Within the 
geographic zone appropriate for a Fund, the optimizer recommends positions in 
companies which in the aggregate constitute the most efficient portfolio.  
The optimizer simultaneously considers total company alphas, trading alphas, 
and risk and quantifies the expected "net benefit" to the portfolio of each 
recommended transaction.  No transaction will be executed unless the 
opportunity offered by a purchase or sale candidate sufficiently exceeds the 
potential of an existing holding to justify the transaction costs.  In most 
markets, portfolios are reoptimized continuously throughout the day, allowing 
the Manager to respond immediately to investment opportunities.

     TRADING.  The Manager's trading system aggregates the recommended 
transactions for a Fund and determines the feasibility of each recommendation 
in light of the stock's liquidity, the expected transaction costs, and 
general market conditions.  It relays target price information to a trader 
for each stock considered for purchase or sale.  Trades are executed through 
any one of four trading strategies: traditional brokerage, networks, 
accommodation, and package or "basket" trades.

     The network arrangements the Manager has developed with Instinet 
Matching System (IMS), Portfolio System for Institutional Trading (POSIT), 
and the Arizona Stock Exchange (AZX) facilitate large volume trading with 
little or no price disturbance and low commission rates.

     Accommodative trading (which we also refer to as the Manager's "match 
system") allows institutional buyers and sellers of stock to electronically 
present the Manager with their "interest" lists each morning.  Any matches 
between the inventory which the brokers have presented and the Manager's own 
recommended trades are signaled to the Manager's traders.  Since the broker 
is doing agency business and has a client on the other side of the trade, the 
Manager expects that the other side will be accommodative in the price.  The 
Manager's objective in using this match system is to execute most trades on 
the Manager's side of the bid/ask spread so as to minimize market impact.

     Package trades further allow the Manager to trade large lists of orders 
simultaneously using state of the art tools such as the Instinet Real-Time 
System, Instinet Order Matching System and Lattice Trading System.  Those 
tools provide order entry, negotiation and execution capabilities, either 
directly to other institutions or electronically to the floor of the 
exchange.  The advantages of using such systems include speed of execution, 
low commissions, anonymity and very low market impact.

     The Manager continuously monitors trading costs to determine the impact 
of commissions and price disturbance on a Fund's portfolio.

INDIVIDUALS RESPONSIBLE FOR THE FUNDS

     Each of the following General Partners of the Manager holds a greater 
than 5% interest in the Manager: Marlis S. Fritz and Kenneth Reid.  Rosenberg 
Alpha L.P., a California limited partnership, is a limited partner of the 
Manager and holds a greater than 5% interest in the Manager.  Barr M. 
Rosenberg, the Managing General Partner of the Manager, and his wife, June 
Rosenberg, each holds a greater than 5% general partnership interest in 
Rosenberg Alpha L.P.

     Management of the portfolio of each Fund is overseen by the Manager's 
General Partners who are responsible for the design and maintenance of the 
Manager's portfolio system, and by a portfolio manager who is responsible for 
research and monitoring each Fund's characteristic performance against the 
relevant benchmark and for monitoring cash balances.

     Dr. Rosenberg, Dr. Reid and F. William Jump, Jr., the portfolio manager, 
are responsible for the day-to-day management of each Fund's portfolio.  Dr. 
Rosenberg and Dr. Reid both have been employed by the Manager since 1985.  
Mr. Jump has had numerous responsibilities including trading, applications 
programming, new product development and portfolio engineering since he 
joined the Manager in 1990.  He received a B.A. from Swarthmore College in 
1977 and a M.B.A. from The Wharton School, University of Pennsylvania in 1983.

MANAGEMENT CONTRACTS

     Under a Management Contract with the Trust on behalf of each Fund, the 
Manager selects and reviews each Fund's investments and provides executive 
and other personnel for the management of the Trust.  Pursuant to the Trust's 
Agreement and Declaration of Trust, as amended, the Board of Trustees 
supervises the affairs of the Trust as conducted by the Manager.  In the 
event that the Manager ceases to be the manager of a Fund, the right of the 
Trust to use the identifying name "Barr Rosenberg" and/or "Rosenberg" may be 
withdrawn.

     Each Fund will pay all other expenses incurred in the operation of such 
Fund, including, but not limited to, brokerage commissions and transfer taxes 
in connection with the Fund's portfolio transactions, all applicable taxes 
and filing fees, distribution fees, shareholder servicing fees, the fees and 
expenses for registration or qualification of its shares under the federal or 
state securities laws, the compensation of trustees who are not partners, 
officers or employees of the Manager, interest charges, expenses of issue or 
redemption of shares, charges of custodians, auditing and legal expenses, 
expenses of determining net asset value of Fund shares, expenses of reports 
to shareholders, expenses of meetings of shareholders, expenses of printing 
and mailing prospectuses, proxy statements and proxies to existing 
shareholders, insurance premiums and professional association dues or 
assessments.

     In addition, each Fund has agreed to pay the Manager a quarterly 
management fee at the annual percentage rate of such Fund's average daily net 
assets set forth below.  The Manager has voluntarily undertaken to waive some 
or all of its management fee and, if necessary, to bear certain expenses of 
each Fund until further notice to the extent required to limit the total 
annual operating expenses (which do not include nonrecurring account fees and 
extraordinary expenses) of each class of shares to the percentage of each 
Fund's average daily net assets attributable to that class listed in the 
Expense Limitation column below.  The Manager's fee for management of the 
Barr Rosenberg Market Neutral Fund is higher than that paid by most other 
mutual funds although the Manager believes it is competitive with the fees 
for similar collective investment vehicles.

ADMINISTRATOR, TRANSFER AGENT AND CUSTODIAN

     BISYS Fund Services (the "Administrator"), a wholly-owned subsidiary of 
The BISYS Group, Inc., serves as the Trust's administrator and generally 
assists the Trust in all aspects of its administration and operation.  As 
compensation for its administrative services, the Administrator receives a 
monthly fee based upon an annual percentage rate of 0.15% of the aggregate 
average daily net assets of the Trust.

     BISYS Fund Services, Inc. (the "Transfer Agent") has entered into an 
agreement with the Trust for the provision of transfer agency services and 
dividend disbursing services for the Trust.  The principal business address 
of the Transfer Agent is 3435 Stelzer Road, Columbus, Ohio 43219.

     Custodial Trust Company (the "Custodian") serves as custodian of the 
assets of the Funds.  The principal address of the Custodian is 101 Carnegie 
Center, Princeton, New Jersey 08540.

DISTRIBUTOR

     Investor Shares of the Funds are sold on a continuous basis by the 
Trust's distributor, Barr Rosenberg Funds Distributor, Inc. (the 
"Distributor"), a wholly-owned subsidiary of BISYS.  The Distributor's 
principal offices are located at 125 West 55th Street, 11th Floor, New York, 
NY 10019.  Institutional Shares are sold directly by the Funds.

     Solely for the purpose of compensating the Distributor for services and 
expenses primarily intended to result in the sale of Investor Shares of the 
Funds, such shares are subject to an annual Distribution Fee of up to 0.50% 
of the average daily net assets attributable to such shares in accordance 
with a Distribution Plan (the "Distribution Plan") adopted by the Trust 
pursuant to Rule 12b-1 under the 1940 Act. Currently, each Fund pays the 
Distributor an annual Distribution Fee of 0.25% of each Fund's average daily 
net assets attributable to Investor Shares.  Activities for which the 
Distributor may be reimbursed include (but are not limited to) the 
development and implementation of direct mail promotions and advertising for 
each Fund, the preparation, printing and distribution of prospectuses for the 
Funds to recipients other than existing shareholders, and contracting with 
one or more wholesalers of the Funds' shares.  The Distribution Plan is of 
the type known as a "compensation" plan.  This means that, although the 
Trustees of the Trust are expected to take into account the expenses of the 
Distributor in their periodic review of the Distribution Plan, the fees are 
payable to compensate the Distributor for services rendered even if the 
amount paid exceeds the Distributor's expenses.

     The Distributor may also provide (or arrange for another intermediary or 
agent to provide) personal and/or account maintenance services to Investor 
shareholders of the Funds (the Distributor or such entity is referred to as a 
"Servicing Agent" in such capacity).  A Servicing Agent will be paid some or 
all of the Shareholder Servicing Fees charged with respect to Investor Shares 
of the Funds pursuant to a Servicing Plan for such shares.

                                  MULTIPLE CLASSES

     As indicated previously, the Funds offer two classes of shares to 
investors, with eligibility generally depending on the amount invested in a 
particular Fund.  The two classes of shares are Institutional Shares and 
Investor Shares.  The following table sets forth basic investment and fee 
information for each class.

*    Certain exceptions apply.  See "Institutional Shares" and "Investor 
Shares" below."

     The offering price of Fund shares is based on the net asset value per 
share next determined after an order is received.  See "Purchase of Shares" 
and "Redemption of Shares."

INSTITUTIONAL SHARES

     Institutional Shares may be purchased by endowments, foundations and 
plan sponsors of 401(a), 401(k), 457 and 403(b) plans and by individuals.  In 
order to be eligible to purchase Institutional Shares, an institution, plan 
or individual must make an initial investment of at least $1 million in the 
particular Fund.  In its sole discretion, the Manager may waive this minimum 
investment requirement and the Manager intends to do so for employees of the 
Manager, for the spouse, parents, children, siblings, grandparents or 
grandchildren of such employees, for employees of the Administrator and for 
Trustees of the Trust who are not interested persons of the Trust or Manager 
and their spouses.  Institutional Shares are sold without any initial or 
deferred sales charges and are not subject to any ongoing distribution 
expenses or shareholder servicing fees.

INVESTOR SHARES

     Investor Shares may be purchased by intermediary financial institutions 
and certain individual retirement accounts and individuals.  In order to be 
eligible to purchase Investor Shares, an eligible investor must make an 
initial investment of at least $2,500 in the particular Fund.  In its sole 
discretion, the Manager may waive this minimum investment requirement.  
Investor Shares are subject to an annual Shareholder Service Fee equal to 
0.25% of the average daily net assets attributable to Investor Shares and an 
annual Distribution Fee equal to 0.25% of the average daily net assets 
attributable to Investor Shares.  As described above, the Distribution Plan 
for Investor Shares permits payments of up to 0.50% of the Funds' average 
daily net assets attributable to Investor Shares.

GENERAL

     The Shareholder Service Fee charged with respect to Investor Shares is 
intended to be compensation for personal services rendered and for account 
maintenance with respect to such shares.  The Distribution Fee charged with 
respect to Investor Shares is intended to compensate the Distributor for 
services and expenses primarily intended to result in the sale of Investor 
Shares.  See "Multiple Classes -- Distributor".

     As described above, shares of the Funds 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 Funds through a Shareholder 
Organization may be charged a transaction-based fee or other fee for the 
services provided by the Shareholder Organization.  Each such 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 of Fund shares.  Customers of 
Shareholder Organizations should read this Prospectus in light of the terms 
governing accounts with their particular organization.

                                 PURCHASE OF SHARES

     The offering price for shares of each Fund is the net asset value per 
share next determined after receipt of a purchase order.  See "Determination 
of Net Asset Value."  Investors may be charged an additional fee by their 
broker or agent if they effect transactions through such persons.

INITIAL CASH INVESTMENTS BY WIRE

     Subject to acceptance by the Trust, shares of the Funds may be purchased 
by wiring federal funds.  Please call 1-800-447-3332 for complete wiring 
instructions.  A completed Account Application must be overnighted to the 
Trust at Barr Rosenberg Series Trust c/o BISYS Fund Services, Inc., 3435 
Stelzer Road, Columbus, Ohio 43219-8021.  Notification must be given to the 
Trust at 1-800-447-3332 prior to 4:00 p.m., New York Time, of the wire date.  
Federal funds purchases will be accepted only on a day on which the Trust, 
the Distributor and the custodian bank are all open for business.

INITIAL CASH INVESTMENTS BY MAIL

     Subject to acceptance by the Trust, an account may be opened by 
completing and signing an Account Application and mailing it to Barr 
Rosenberg Series Trust, P.O. Box 182495, Columbus, Ohio 43219-2495.

     The Fund(s) to be purchased should be specified on the Account 
Application. In all cases, subject to acceptance by the Trust, payment for 
the purchase of shares received by mail will be credited to a shareholder's 
account at the net asset value per share of a Fund next determined after 
receipt, even though the check may not yet have been converted into federal 
funds.

ADDITIONAL CASH INVESTMENTS

     Additional cash investments may be made at any time by mailing a check 
to the Trust at the address noted under "Initial Cash Investments by Mail" 
(payable to Barr Rosenberg Series Trust) or by wiring monies as noted under 
"Initial Cash Investments by Wire".  Notification must be given at 
1-800-447-3332 prior to 4:00 p.m., New York time, of the wire date.  The 
minimum amounts for additional cash investments are $10,000 for Institutional 
Shares and $500 for Investor Shares.  In its sole discretion, the Manager may 
waive the minimum additional investment requirements.

INVESTMENTS IN-KIND (INSTITUTIONAL SHARES)

     Institutional Shares may be purchased in exchange for common stocks on 
deposit at The Depository Trust Company ("DTC") or by a combination of such 
common stocks and cash.  Purchase of Institutional Shares of a Fund in 
exchange for stocks is subject in each case to the determination by the 
Manager that the stocks to be exchanged are acceptable.  Securities accepted 
by the Manager in exchange for Fund shares will be valued as set forth under 
"Determination of Net Asset Value" (generally the last quoted sale price) as 
of the time of the next determination of net asset value after such 
acceptance.  All dividends, subscription or other rights which are reflected 
in the market price of accepted securities at the time of valuation become 
the property of the Fund and must be delivered to the Fund upon receipt by 
the investor from the issuer.  Generally, the exchange of common stocks for 
Institutional Shares will be a taxable event for federal income tax purposes, 
which will trigger gain or loss to an investor subject to federal income 
taxation, measured by the difference between the value of the Institutional 
Shares received and the investor's basis in the securities tendered.

     The Manager will not approve the acceptance of securities in exchange 
for Fund shares unless (1) the Manager, in its sole discretion, believes the 
securities are appropriate investments for the Fund; (2) the investor 
represents and agrees that all securities offered to the Fund are not subject 
to any restrictions upon their sale by the Fund under the Securities Act of 
1933, or otherwise; and (3) the securities may be acquired under the Fund's 
investment restrictions.

OTHER PURCHASE INFORMATION

                                      -20-

<PAGE>

     An eligible shareholder may also participate in the Barr Rosenberg 
Automatic Investment Program, an investment plan that automatically debits 
money from the shareholder's bank account and invests it in Investor Shares 
of one or more of the Funds through the use of electronic funds transfers.  
Investors may commence their participation in this program with a minimum 
initial investment of $2,500 and may elect to make subsequent investments by 
transfers of a minimum of $50 into their established Fund account.  You may 
contact the Trust for more information about the Barr Rosenberg Automatic 
Investment Program.

     For purposes of calculating the purchase price of Fund shares, a 
purchase order is received by the Trust on the day that it is in "good order" 
unless it is rejected by the Distributor.  For a purchase order of Investor 
Shares to be in "good order" on a particular day a check or money wire must 
be received on or before 4:00 p.m., New York Time of that day.  In the case 
of Institutional Shares, the investor's securities must be placed on deposit 
at the Depository Trust Company prior to 10:00 a.m., New York Time or, in the 
case of cash investments, the Trust must have received adequate assurances 
that federal funds will be wired to a Fund prior to 4:00 p.m., New York Time, 
on the following business day.  If the consideration is received by the Trust 
after the deadline, the purchase price of Fund shares will be based upon the 
next determination of net asset value of Fund shares.  No third party or 
foreign checks will be accepted.

     The Trust reserves the right, in its sole discretion, to suspend the 
offering of shares of a Fund or to reject purchase orders when, in the 
judgment of the Manager, such suspension or rejection would be in the best 
interests of the Trust.

     Purchases of each Fund's shares may be made in full or in fractional 
shares of such Fund calculated to three decimal places.  In the interest of 
economy and convenience, certificates for shares will not be issued.

                                     IRA ACCOUNTS

     Investor Shares of the Funds may be used as a funding medium for IRAs.  
The minimum initial investment for an IRA is $2,000.  A special application 
must be completed in order to create such an account.  Contributions to IRAs 
are subject to prevailing amount limits set by the Internal Revenue Service.  
For more information about IRAs, call the Trust at 1-800-447-3332.

                                 REDEMPTION OF SHARES

     Shares of the Funds may be redeemed by mail, or, if authorized by an 
investor in an account application, by telephone.  The value of shares 
redeemed may be more or less than the original cost of those shares, 
depending on the market value of the investment securities held by the 
particular Fund at the time of the redemption.

BY MAIL

     The Trust will redeem its shares at the net asset value next determined 
after the request is received in "good order".  See "Determination of Net 
Asset Value."  Requests should be addressed to Barr Rosenberg Series Trust, 
P.O. Box 182495, Columbus, Ohio 43219-2495.

     Requests in "good order" must include the following documentation:

          (a)  a letter of instruction, if required, 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 they are registered;

          (b)  any required signature guarantees (see "Signature Guarantees"  
     below); and

                                      -21-

<PAGE>

          (c)  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 shareholder accounts, the Trust and its transfer agent from 
fraud, signature guarantees are required to enable the Trust 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) at the 
registered address, (2) redemptions of $25,000 or more, and (3) share 
transfer requests. Signature guarantees may be obtained from certain eligible 
financial institutions, including but not limited to, the following: banks, 
trust companies, credit unions, securities brokers and dealers, savings and 
loan associations and participants in the Securities and Transfer Association 
Medallion Program ("STAMP"), the Stock Exchange Medallion Program ("SEMP") or 
the New York Stock Exchange Medallion Signature Program ("MSP").  
Shareholders may contact the Trust at 1-800-447-3332 for further details.

BY TELEPHONE

     Provided the Telephone Redemption Option has been authorized by an 
investor in an account application, a redemption of shares may be requested 
by calling the Transfer Agent at 1-800-447-3332 and requesting that the 
redemption proceeds be mailed to the primary registration address or wired 
per the authorized instructions.  If the Telephone Redemption Option or the 
Telephone Exchange Option (as described below) is authorized, the Transfer 
Agent may act on telephone instruction from any person representing himself 
or herself to be a shareholder and believed by the Transfer Agent to be 
genuine.  The Transfer Agent's records of such instructions are binding and 
the shareholder, and not the Trust or the Transfer Agent, bears the risk of 
loss in the event of unauthorized instructions reasonably believed by the 
Transfer Agent to be genuine.  The Transfer Agent will employ reasonable 
procedures to confirm that instructions communicated are genuine and, if it 
does not, it may be liable for any losses due to unauthorized or fraudulent 
instructions.  The procedures employed in connection with transactions 
initiated by telephone include tape recording of telephone instructions and 
requiring some form of personal identification prior to acting upon 
instructions received by telephone. Telephone Redemption will be suspended 
for a period of 10 days following a telephonic address change.

SYSTEMATIC WITHDRAWAL PLAN

     An owner of $12,000 or more of shares of a Fund may elect to have 
periodic redemptions made from the investor's account to be paid on a 
monthly, quarterly, semiannual or annual basis.  The maximum payment per year 
is 12% of the account value at the time of the election.  The shareholder 
will normally redeem a sufficient number of shares to make the scheduled 
redemption payments on a date selected by the shareholder.  Depending on the 
size of the payment requested and fluctuation in the net asset value, if any, 
of the shares redeemed, redemptions for the purpose of making such payments 
may reduce or even exhaust the account. A shareholder may request that these 
payments be sent to a predesignated bank or other designated party.  Capital 
gains and dividend distributions paid to the account will automatically be 
reinvested at net asset value on the distribution payment date.

FURTHER REDEMPTION INFORMATION

     Purchases of shares of the Trust made by check are not permitted to be 
redeemed until payment of the purchase price has been collected, which may 
take up to fifteen days after purchase.  Shareholders can avoid this delay by 
utilizing the wire purchase option.

     If the Manager determines, in its sole discretion, that it would not be 
in the best interests of the remaining shareholders of a Fund to make a 
redemption payment wholly or partly in cash, such Fund may pay the redemption 
price of Institutional Shares in whole or in part by a distribution in kind 
of readily marketable securities held by such

                                      -22-

<PAGE>

Fund in lieu of cash.  Securities used to redeem Fund shares in kind will be 
valued in accordance with the Funds' procedures for valuation described under 
"Determination of Net Asset Value." Securities distributed by a Fund in kind 
will be selected by the Manager in light of each Fund's objective and will 
not generally represent a PRO RATA distribution of each security held in a 
Fund's portfolio.  Investors may incur brokerage charges on the sale of any 
such securities so received in payment of redemptions.

     The Trust may suspend the right of redemption and may postpone payment 
for more than seven days when the New York Stock Exchange is closed for other 
than weekends or holidays, or if permitted by the rules of the Securities and 
Exchange Commission, during periods when trading on the Exchange is 
restricted or during an emergency which makes it impracticable for the Funds 
to dispose of their securities or to fairly determine the value of their net 
assets, or during any other period permitted by the Securities and Exchange 
Commission for the protection of investors.

                              EXCHANGE OF FUND SHARES
   
     The Funds offer two convenient ways to exchange shares in one Fund for 
shares of another Fund.  Shares of a particular class of a Fund may be 
exchanged only for shares of the same class in another Fund.  There is no 
sales charge on exchanges.  Before engaging in an exchange transaction, a 
shareholder should read carefully the information in the Prospectus 
describing the Fund into which the exchange will occur.  A shareholder may 
not exchange shares of a class of one Fund for shares of the same class of 
another Fund that is not qualified for sale in the state of the shareholder's 
residence.  Although the Trust has no current intention of terminating or 
modifying the exchange privilege, it reserves the right to do so at any time.
    
     An exchange is taxable as a sale of a security on which a gain or loss 
may be recognized.  Shareholders should receive written confirmation of the 
exchange within a few days of the completion of the transaction.

     A new account opened by exchange must be established with the same 
name(s), address and social security number as the existing account.  All 
exchanges will be made based on the respective net asset values next 
determined following receipt of the request by the Funds containing the 
information indicated below.

EXCHANGE BY MAIL

     To exchange Fund shares by mail, shareholders should simply send a 
letter of instruction to the Trust.  The letter of instruction must include: 
(a) the investor's account number; (b) the class of shares to be exchanged; 
(c) the Fund from and the Fund into which the exchange is to be made; (d) the 
dollar or share amount to be exchanged; and (e) the signatures of all 
registered owners or authorized parties.

EXCHANGE BY TELEPHONE

     To exchange Fund shares by telephone or to ask questions about the 
exchange privilege, shareholders may call the Trust at 1-800-447-3332.  If 
you wish to exchange shares, please be prepared to give the telephone 
representative the following information: (a) the account number, social 
security number and account registration; (b) the class of shares to be 
exchanged; (c) the name of the Fund from which and the Fund into which the 
exchange is to be made; and (d) the dollar or share amount to be exchanged.  
Telephone exchanges are available only if the shareholder so indicates by 
checking the "yes" box on the Account Application.  The Trust employs 
procedures, including recording telephone calls, testing a caller's identity, 
and sending written confirmation of telephone transactions, designed to give 
reasonable assurance that instructions communicated by telephone are genuine, 
and to discourage fraud.  To the extent that a Fund does not follow such 
procedures, it may be liable for losses due to unauthorized or fraudulent 
telephone instructions.  A Fund will not be liable for acting upon 
instructions communicated by telephone that it reasonably believes to be 
genuine.  The Trust reserves the right to suspend or

                                     -23-

<PAGE>

terminate the privilege of exchanging by mail or by telephone at any time.  
The telephone exchange privilege will be suspended for a period of 10 days 
following a telephonic address change.

                          DETERMINATION OF NET ASSET VALUE

     The net asset value of each class of shares of the Funds will be 
determined once on each day on which the New York Stock Exchange is open as 
of 4:00 p.m., New York time.

     The net asset value per share of each class of the Funds is determined 
by dividing the particular class's proportionate interest in the total market 
value of the Fund's portfolio investments and other assets, less any 
applicable liabilities, by the total outstanding shares of that class of such 
Fund. Specifically, each Fund's liabilities are allocated among its classes.  
The total of such liabilities allocated to a particular class plus that 
class's shareholder servicing and/or distribution expenses, if any, and any 
other expenses specially allocated to that class are then deducted from the 
class's proportionate interest in a Fund's assets.  The resulting amount for 
each class is divided by the number of shares of that class outstanding to 
produce the net asset value per share.

     Portfolio securities listed on a securities exchange for which market 
quotations are available are valued at the last quoted sale price on each 
business day, or, if there is no such reported sale, at the most recent 
quoted bid price.  Price information on listed securities is generally taken 
from the closing price on the exchange where the security is primarily 
traded.  Unlisted securities for which market quotations are readily 
available are valued at the most recent quoted bid price, except that debt 
obligations with sixty days or less remaining until maturity may be valued at 
their amortized cost. Exchange-traded options on futures are valued at the 
settlement price as determined by the appropriate clearing corporation.  
Futures contracts are valued by computing the gain or loss by reference to 
the current settlement price as determined by the appropriate clearing 
corporation.  Other assets and securities for which no quotations are readily 
available are valued at fair value as determined in good faith by the 
Trustees of the Trust or by persons acting at their direction.
                                          
                                          
                                   DISTRIBUTIONS

     Each Fund intends to pay out as dividends substantially all of its net 
investment income (which comes from dividends and any interest it receives 
from its investments and net short-term capital gains).  Each Fund also 
intends to distribute substantially all of its net long-term capital gains, 
if any, after giving effect to any available capital loss carryover.  Each 
Fund's policy is to declare and pay distributions of its dividends and 
interest annually although it may do so more frequently as determined by the 
Trustees of the Trust.  Each Fund's policy is to distribute net short-term 
capital gains and net long-term gains annually, although it may do so more 
frequently as determined by the Trustees of the Trust to the extent permitted 
by applicable regulations.

     All dividends and/or distributions will be paid out in the form of 
additional shares of the relevant Fund to which the dividends and/or 
distributions relate at net asset value unless the shareholder elects to 
receive cash.  Shareholders may make this election by marking the appropriate 
box on the Account Application or by writing to the Administrator.

     If you elect to receive distributions in cash and checks (1) are 
returned and marked as "undeliverable" or (2) remain uncashed for six months, 
your cash election will be changed automatically and your future dividend and 
capital gains distributions will be reinvested in the Fund at the per share 
net asset value determined as of the date of payment of the distribution.  In 
addition, any undeliverable checks or checks that remain uncashed for six 
months will be canceled and will be reinvested in the Fund at the per share 
net asset value determined as of the date of cancellation.

                                       TAXES
   
     Each Fund intends to qualify each year as a regulated investment company 
under Subchapter M of the Internal Revenue Code of 1986, as amended.  So long 
as a Fund distributes, as dividends, substantially all of the sum of its 
taxable net investment income, its net tax-exempt income (if any), and, the 
excess, if any, of net short-term capital gains over net long-term capital 
losses for such year and otherwise qualifies for the special rules governing 
the taxation of regulated investment companies, the Fund itself will not pay 
federal income tax on the amount distributed.  Such dividends will be taxable 
to shareholders subject to income tax as ordinary income.  Distributions 
designated by the Fund as deriving from net gains on capital assets held for 
more than one year but not more than 18 months and from net gains on capital 
assets held for more than 18 months will be taxable to shareholders as such, 
regardless of how long a shareholder has held the shares.  Distributions will 
be taxed as described above whether received in cash or in shares through the 
reinvestment of distributions. A distribution paid to shareholders by a Fund 
in January of a year is generally deemed to have been received by 
shareholders on December 31 of the preceding year, if the distribution was 
declared and payable to shareholders of record on a date in October, November 
or December of that preceding year.  Each Fund will provide federal tax 
information annually, including information about dividends and distributions 
paid during the preceding year.
    
   
     To the extent such investments are permissible for a Fund, the Fund's 
short sales and transactions in options, futures contracts, hedging 
transactions, forward contracts, equity swap contracts and straddles will be 
subject to special tax rules (including mark-to-market, constructive sale, 
straddle, wash sale and short sale rules), the effect of which may be to 
accelerate income to the Fund, defer losses to the Fund, cause adjustments in 
the holding periods of the Fund's securities and convert short-term capital 
losses into long-term capital losses.  These rules could therefore affect the 
amount, timing and character of distributions to shareholders.  A Fund's use 
of such transactions may result in the Fund realizing more short-term capital 
gains and ordinary income subject to tax at ordinary income tax rates than it 
would if it did not engage in such transactions.
    
     The foregoing is a general summary of the federal income tax 
consequences of investing in a Fund to shareholders who are U.S. citizens or 
U.S. corporations.  Shareholders should consult their own tax advisers about 
the tax consequences of an investment in the Funds in light of each 
shareholder's particular tax situation.  Shareholders should also consult 
their own tax advisers about consequences under foreign, state, local or 
other applicable tax laws.

                  DESCRIPTION OF THE TRUST AND OWNERSHIP OF SHARES

     The Trust is a diversified open-end series management investment company 
organized as a Massachusetts business trust under the laws of The 
Commonwealth of Massachusetts by an Agreement and Declaration of Trust dated 
April 1, 1988, as amended from time to time (the "Declaration of Trust").

     The Declaration of Trust permits the Trustees to issue an unlimited 
number of full and fractional shares of beneficial interest which are 
presently divided into five series.  Interests in each of the Funds described 
in this Prospectus are represented by shares of such Fund.  The Declaration 
of Trust also permits the Trustees, without shareholder approval, to 
subdivide any series of shares into various sub-series of shares with such 
preferences and other rights as the Trustees may designate.  While the 
Trustees have no current intention to exercise this power, it is intended to 
allow them to provide for an equitable allocation of the impact of any future 
regulatory requirements which might affect various classes of shareholders 
differently.  The Trustees may also, without shareholder approval, establish 
one or more additional separate portfolios for investments in the Trust, 
terminate a series of the Trust or merge two or more existing portfolios.  
Shareholders' investments in such a portfolio would be evidenced by a 
separate series of shares.

     Each Fund is further divided into two classes of shares designated as 
Institutional Shares and Investor Shares.  Each class of shares of a Fund 
represents interests in the assets of such Fund and has identical dividend, 
liquidation

                                      -25-

<PAGE>

and other rights and the same terms and conditions except that expenses, if 
any, related to the distribution and shareholder servicing of a particular 
class are borne solely by such class and each class may, at the Trustees' 
discretion, also pay a different share of other expenses, not including 
advisory or custodial fees or other expenses related to the management of the 
Trust's assets, if these expenses are actually incurred in a different amount 
by that class, or if the class receives services of a different kind or to a 
different degree than the other classes.  All other expenses are allocated to 
each class on the basis of the net asset value of that class in relation to 
the net asset value of such Fund.

     Each class of shares of a Fund has identical voting rights except that 
each class has exclusive voting rights on any matter submitted to 
shareholders that relates solely to that class, and has separate voting 
rights on any matter submitted to shareholders in which the interests of one 
class differ from the interests of any other class.  Each class of shares has 
exclusive voting rights with respect to matters pertaining to any 
distribution or servicing plan applicable to that class.  Matters submitted 
to shareholder vote must be approved by each Fund separately except (i) when 
required by the Investment Company Act of 1940, all shares shall be voted 
together and (ii) when the Trustees have determined that the matter does not 
affect all Funds, then only shareholders of the Fund or Funds affected shall 
be entitled to vote on the matter.  All classes of shares of a Fund will vote 
together, except with respect to any distribution or servicing plan 
applicable to a class or when a class vote is required as specified above or 
otherwise by the Investment Company Act of 1940.  Shares are freely 
transferable, are entitled to dividends as declared by the Trustees and, in 
liquidation of a Fund portfolio, are entitled to receive the net assets of 
that portfolio, but not of the other Funds.  The Trust does not generally 
hold annual meetings of shareholders and will do so only when required by 
law.  Shareholders holding a majority of the outstanding shares may remove 
Trustees from office by votes cast in person or by proxy at a meeting of 
shareholders or by written consent.

     The Declaration of Trust provides for the perpetual existence of the 
Trust. The Trust, may, however, be terminated at any time by vote of at least 
two-thirds of the outstanding shares of each series of the Trust.
   
     Shareholders could, under certain circumstances, be held personally 
liable for the obligations of the Trust.  However, the risk of a shareholder 
incurring financial loss on account of that liability is considered remote 
since it may arise only in very limited circumstances.

                          INVESTMENT OBJECTIVES AND POLICIES

     The investment objective and policies of each of the Barr Rosenberg 
Market Neutral Fund and Barr Rosenberg Double Alpha Market Fund (each, a 
"Fund" and collectively, the "Funds") of Barr Rosenberg Series Trust (the 
"Trust") are summarized on the front page of the Prospectus and in the text 
of the Prospectus under the headings "Investment Objectives and Policies" and 
"General Description of Risks and Fund Investments."

     In addition, the following is an additional description of certain 
investments of the Fund(s).

     SHORT SALES (BOTH FUNDS).  The Barr Rosenberg Market Neutral Fund will 
seek, and the Barr Rosenberg Double Alpha Market Fund may seek, to realize 
additional gains through short sales.  Short sales are transactions in which 
a Fund sells a security it does not own, in anticipation of a decline in the 
value of that security relative to the long positions held by the Fund.  To 
complete such a transaction, a Fund must borrow the security to make delivery 
to the buyer.  A Fund then is obligated to replace the security borrowed by 
purchasing it at the market price at or prior to the time of replacement.  
The price at such time may be more or less than the price at which the 
security was sold by a Fund.  Until the security is replaced, a Fund is 
required to repay the lender any dividends or interest that accrue during the 
period of the loan.  To borrow the security, a Fund also may be required to 
pay a premium, which would increase the cost of the security sold.  The net 
proceeds of the short sale will be retained by the broker (or by the Fund's 
custodian in a special custody account), to the extent necessary to meet 
margin requirements, until the short position is closed out.  A Fund also 
will incur transaction costs in effecting short sales.

     A Fund will incur a loss as a result of the short sale if the price of 
the security increases between the date of the short sale and the date on 
which the Fund replaces the borrowed security.  A Fund will realize a gain if 
the security declines in price between those dates.  The amount of any gain 
will be decreased, and the amount of any loss increased, by the amount of the 
premium, dividends, interest or expenses a Fund may be required to pay in 
connection with a short sale.  An increase in the value of a security sold 
short by a Fund over the price at which it was sold short will result in a 
loss to the Fund, and there can be no assurance that the Fund will be able to 
close out the position at any particular time or at an acceptable price.

     S&P 500 INDEX FUTURES AND RELATED OPTIONS (BARR ROSENBERG DOUBLE ALPHA 
MARKET FUND ONLY).  An S&P 500 Index Future contract (an "Index Future") is a 
contract to buy or sell an integral number of units of the Standard & Poor's 
500 Composite Stock Price Index (the "S&P 500 Index") at a specified future 
date at a price agreed upon when the contract is made.  A unit is the value 
of the S&P 500 Index from time to time.  Entering into a contract to buy 
units is commonly referred to as buying or purchasing a contract or holding a 
long position in the S&P 500 Index.

     Index Futures can be traded through all major commodity brokers. 
Currently, contracts are expected to expire on the tenth day of March, June, 
September and December.  The Barr Rosenberg Double Alpha Market Fund will 
ordinarily be able to close open positions on the United States futures 
exchange on which Index Futures are then traded at any time up to and 
including the expiration day.

     In contrast to purchases of a common stock, no price is paid or received 
by the Barr Rosenberg Double Alpha Market Fund upon the purchase of a futures 
contract.  Upon entering into a futures contract, the Fund will be required 
to deposit with its custodian in a segregated account in the name of the 
futures broker a specified amount of cash or securities.  This is known by 
participants in the market as "initial margin".  The type of instruments that 
may be deposited as initial margin, and the required amount of initial 
margin, are determined by the futures exchange(s) on which the Index Futures 
are traded. The nature of initial margin in futures transactions is different 
from that of margin in securities transactions in that futures contract 
margin does not involve the borrowing of funds by the customer to finance the 
transactions. Rather, the initial margin is in the nature of a performance 
bond or good faith deposit on the contract which is returned to the Fund upon 
termination of the futures contract, assuming all contractual obligations 
have been satisfied. Subsequent payments, called "variation margin", to and 
from the broker, will be

                                      -3-

<PAGE>

made on a daily basis as the price of the S&P 500 Index fluctuates, making 
the position in the futures contract more or less valuable, a process known 
as "marking to the market".  For example, when the Fund has purchased an 
Index Future and the price of the S&P 500 Index has risen, that position will 
have increased in value and the Fund will receive from the broker a variation 
margin payment equal to that increase in value.  Conversely, when the Fund 
has purchased an Index Future and the price of the S&P 500 Index has 
declined, the position would be less valuable and the Fund would be required 
to make a variation margin payment to the broker.  When the Fund terminates a 
position in a futures contract, a final determination of variation margin is 
made, additional cash is paid by or to the Fund, and the Fund realizes a gain 
or a loss.

     The price of Index Futures may not correlate perfectly with movement in 
the underlying index due to certain market distortions.  First, all 
participants in the futures market are subject to margin deposit and 
maintenance requirements. Rather than meeting additional margin deposit 
requirements, investors may close futures contracts through offsetting 
transactions which could distort the normal relationship between the S&P 500 
Index and futures markets.  Secondly, the deposit requirements in the futures 
market are less onerous than margin requirements in the securities market, 
and as a result the futures market may attract more speculators than does the 
securities market.  Increased participation by speculators in the futures 
market may also cause temporary price distortions.

     Options on index futures contracts give the purchaser the right, in 
return for the premium paid, to assume a position in an index futures 
contract (a long position if the option is a call and a short position if the 
option is a put) at a specified exercise price at any time during the period 
of the option.  Upon exercise of the option, the holder would assume the 
underlying futures position and would receive a variation margin payment of 
cash or securities approximating the increase in the value of the holder's 
option position.  If an option is exercised on the last trading day prior to 
the expiration date of the option, the settlement will be made entirely in 
cash based on the difference between the exercise price of the option and the 
closing level of the index on which the futures contract is based on the 
expiration date.  Purchasers of options who fail to exercise their options 
prior to the exercise date suffer a loss of the premium paid.

     The ability to establish and close out positions in options on futures 
contracts will be subject to the development and maintenance of a liquid 
secondary market.  It is not certain that such a market will develop.  
Although the Barr Rosenberg Double Alpha Market Fund generally will purchase 
only those options for which there appears to be an active secondary market, 
there is no assurance that a liquid secondary market on an exchange will 
exist for any particular option or at any particular time.  In the event no 
such market exists for particular options, it might not be possible to effect 
closing transactions in such options, with the result that the Fund would 
have to exercise the options in order to realize any profit.

                         MISCELLANEOUS INVESTMENT PRACTICES

     PORTFOLIO TURNOVER.  A change in securities held by a Fund is known as 
"portfolio turnover" and almost always involves the payment by a Fund of 
brokerage commissions or dealer markup and other transaction costs on the 
sale of securities as well as on the reinvestment of the proceeds in other 
securities.  Portfolio turnover is not a limiting factor with respect to 
investment decisions.  As disclosed in the Prospectus, high portfolio 
turnover involves correspondingly greater brokerage commissions and other 
transaction costs, which will be borne directly by the Funds, and could 
involve realization of capital gains that would be taxable when distributed 
to shareholders of a Fund.  To the extent that portfolio turnover results in 
the realization of net short-term capital gains, such gains are ordinarily 
taxed to shareholders at ordinary income tax rates.  See "Portfolio 
Transactions" and "Income Dividends, Distributions and Tax Status".

     NOTICE ON SHAREHOLDER APPROVAL.  Unless otherwise indicated in the 
Prospectus or this Statement of Additional Information, the investment 
objective and policies of each of the Funds may be changed without 
shareholder approval.

                              INVESTMENT RESTRICTIONS

     Without a vote of the majority of the outstanding voting securities of a 
Fund, the Trust will not take any of the following actions with respect to 
such Fund:
   
     (1)  Borrow money in excess of 10% of the value (taken at the lower of 
cost or current value) of the Fund's total assets (not including the amount 
borrowed) at the time the borrowing is made, and then only from banks as a 
temporary measure to facilitate the meeting of redemption requests (not for 
leverage) which might otherwise require the untimely disposition of portfolio 
investments or for extraordinary or emergency purposes or for payments of 
variation margin (in the case of the Barr Rosenberg Double Alpha Market Fund 
only).  Such borrowings will be repaid before any additional investments are 
purchased. Short sales and related borrowings of securities are not subject 
to this restriction.
    
     (2)  Pledge, hypothecate, mortgage or otherwise encumber its assets in 
excess of 10% of the Fund's total assets (taken at cost) and then only to 
secure borrowings permitted by Restriction 1 above.  (For the purposes of 
this restriction, collateral arrangements with respect to options, short 
sales, stock index, interest rate, currency or other futures, options on 
futures contracts and collateral arrangements with respect to initial and 
variation margin are not deemed to be a pledge or other encumbrance of 
assets.  Collateral arrangements with respect to swaps and other derivatives 
are also not deemed to be a pledge or other encumbrance of assets.)

     (3)  Purchase securities on margin, except such short-term credits as 
may be necessary for the clearance of purchases and sales of securities.  
(For this purpose, the deposit or payment of initial or variation margin in 
connection with futures contracts or related options transactions is not 
considered the purchase of a security on margin.)

     (4)  Make short sales of securities or maintain a short position if, 
when added together, more than 100% of the value of a Fund's net assets would 
be (i) deposited as collateral for the obligation to replace securities 
borrowed to effect short sales, and (ii) allocated to segregated accounts in 
connection with short sales.  Short sales "against the box" are not subject 
to this limitation.

     (5)  Underwrite securities issued by other persons except to the extent 
that, in connection with the disposition of its portfolio investments, it may 
be deemed to be an underwriter under federal securities laws.

     (6)  Purchase or sell real estate, although it may purchase securities 
of issuers which deal in real estate, including securities of real estate 
investment trusts, and may purchase securities which are secured by interests 
in real estate.

     (7)  Concentrate more than 25% of the value of its total assets in any 
one industry.

     (8)  Invest in securities of other investment companies, except to the 
extent permitted by the Investment Company Act of 1940, as amended (the "1940 
Act"), or by an exemptive order issued by the Securities and Exchange 
Commission.

     (9)  Purchase or sell commodities or commodity contracts except that 
each of the Funds may purchase and sell stock index and other financial 
futures contracts and options thereon.

     (10) Make loans, except by purchase of debt obligations or by entering 
into repurchase agreements or through the lending of the Fund's portfolio 
securities.

     (11) Issue senior securities.  (For the purpose of this restriction none 
of the following is deemed to be a senior security: any pledge or other 
encumbrance of assets permitted by restriction (2) above; any borrowing 

                                      -5-

<PAGE>

permitted by restriction (1) above; short sales permitted by restriction (4) 
above; any collateral arrangements with respect to short sales, swaps, 
options, future contracts and options on future contracts and with respect to 
initial and variation margin; and the purchase or sale of options, future 
contracts or options on future contracts.)
   
     Notwithstanding the latitude permitted by Restriction 9 above, the Funds 
have no current intention of purchasing interest rate futures.
    
     It is contrary to the present policy of each of the Funds, which may be 
changed by the Trustees of the Trust without shareholder approval, to:

     (a)  Invest in warrants or rights (other than warrants or rights 
acquired by the Fund as a part of a unit or attached to securities at the 
time of purchase).

     (b)  Write, purchase or sell options on particular securities (as 
opposed to market indices).

     (c)  Buy or sell oil, gas or other mineral leases, rights or royalty 
contracts.

     (d)  Make investments for the purpose of exercising control of a 
company's management.

     (e)  Invest in (a) securities which at the time of investment are not 
readily marketable and (b) repurchase agreements maturing in more than seven 
days if, as a result, more than 15% of the Fund's net assets (taken at 
current value) would then be invested in such securities.

     Unless otherwise indicated, all percentage limitations on investments 
set forth herein and in the Prospectus will apply at the time of the making 
of an investment and shall not be considered violated unless an excess or 
deficiency occurs or exists immediately after and as a result of such 
investment.

     The phrase "shareholder approval," as used in the Prospectus and herein, 
and the phrase "vote of a majority of the outstanding voting securities", as 
used herein, means the affirmative vote of the lesser of (1) more than 50% of 
the outstanding shares of a Fund or the Trust, as the case may be, or (2) 67% 
or more of the shares of a Fund or the Trust, as the case may be, present at 
a meeting if more than 50% of the outstanding shares are represented at the 
meeting in person or by proxy.

                   INCOME DIVIDENDS, DISTRIBUTIONS AND TAX STATUS

     The tax status of the Funds and the distributions which they may make 
are summarized in the Prospectus under the heading "Taxes."  The Funds intend 
to qualify each year as a regulated investment company under the Internal 
Revenue Code.  In order to qualify as a "regulated investment company" and to 
qualify for the special tax treatment accorded regulated investment companies 
and their shareholders, each Fund must, among other things, (a) derive at 
least 90% of its gross income from dividends, interest, payments with respect 
to certain securities loans, gains from the sale or other disposition of 
securities or foreign currencies or other income (including but not limited 
to gains from options, futures or forward contracts) derived with respect to 
its business of investing in such securities or currencies; (b) diversify its 
holdings so that, at the close of each quarter of its taxable year, (i) at 
least 50% of the value of its total assets consists of cash, cash items, U.S. 
Government securities, securities of other regulated investment companies, 
and other securities limited generally with respect to any one issuer to not 
more than 5% of the total assets of such Fund and not more than 10% of the 
outstanding voting securities of such issuer, and (ii) not more than 25% of 
the value of its total assets is invested in the securities of any issuer 
(other than U.S. Government securities or securities of other regulated 
investment companies); and (c) distribute annually at least 90% of the sum of 
its taxable net investment income, its net tax-exempt income (if any), and, 
the excess, if any, of net short-term capital gains over net long-term 
capital losses for such year.  To the extent a Fund qualifies for treatment 
as a

                                      -6-

<PAGE>

regulated investment company, the Fund will not be subject to federal income 
tax on income paid to its shareholders in the form of dividends or capital 
gain distributions.

     As described in the Prospectus under the heading "Distributions," each 
Fund intends to pay out substantially all of its ordinary income and net 
short-term capital gains, and to distribute substantially all of its net 
capital gains, if any, after giving effect to any available capital loss 
carryover.  Net capital gain is the excess of net gains from assets held for 
more than one year over net losses from capital assets held for not more than 
one year.  In order to avoid an excise tax imposed on certain undistributed 
income, a Fund must distribute prior to each calendar year end without regard 
to the Fund's fiscal year end (i) 98% of the Fund's ordinary income, and (ii) 
98% of the Fund's capital gain net income, if any, realized in the one-year 
period ending on October 31.

     In general, all dividend distributions derived from ordinary income and 
short-term capital gain are taxable to investors as ordinary income (eligible 
in part for the dividends-received deduction in the case of corporations, 
subject to certain conditions).  Pursuant to the Taxpayer Relief Act of 1997 
(the "1997 Act"), two different tax rates apply to net capital gains.  One 
rate (generally 28%) applies to net gains on capital assets held for more 
than one year but not more than 18 months ("mid-term gains") and a second, 
preferred rate (generally 20%) applies to the balance of such net capital 
gains ("adjusted net capital gains").  Distributions of net capital gains 
will be treated in the hands of shareholders as mid-term gains to the extent 
designated by the Fund as deriving from net gains from assets held for more 
than one year but not more than 18 months, and the balance will be treated as 
adjusted net capital gains. Distributions of mid-term gains and adjusted net 
capital gains will be taxable to shareholders as such, regardless of how long 
a shareholder has held the shares in the Fund.  Distributions will be taxable 
as described above whether received in cash or in shares through the 
reinvestment of distributions.  The dividends-received deduction for 
corporations will generally apply to a Fund's dividends from investment 
income to the extent derived from dividends received by the Fund from 
domestic corporations, provided the Fund and the shareholder each meet the 
relevant holding period requirements.

     Certain tax-exempt organizations or entities may not be subject to 
federal income tax on dividends or distributions from a Fund.  Each 
organization or entity should review its own circumstances and the federal 
tax treatment of its income.

     Each Fund is generally required to withhold and remit to the U.S. 
Treasury 31% of the taxable dividends and other distributions, whether 
distributed in cash or reinvested in shares of the Fund, paid or credited to 
any shareholder account for which an incorrect or no taxpayer identification 
number has been provided or where the Fund is notified that the shareholder 
has under reported income in the past (or the shareholder fails to certify 
that he is not subject to such withholding).  However, the general back-up 
withholding rules set forth above will not apply to tax-exempt entities so 
long as each such entity furnishes a Fund with an appropriate certificate.

     To the extent such investments are permissible for a particular Fund, 
the Fund's transactions in options, futures contracts, hedging transactions, 
forward contracts and straddles will be subject to special tax rules 
(including mark-to-market, constructive sale, straddle, wash sale and short 
sale rules), the effect of which may be to accelerate income to the Fund, 
defer losses to the Fund, cause adjustments in the holding periods of the 
Fund's securities and convert short-term capital losses into long-term 
capital losses.  These rules could therefore affect the amount, timing and 
character of distributions to shareholders.

     Pursuant to the 1997 Act, new "constructive sale" provisions apply to 
activities by a Fund which lock in gain on an "appreciated financial 
position." Generally, a "position" is defined to include stock, a debt 
instrument, or partnership interest, or an interest in any of the foregoing, 
including through a short sale, a swap contract, or a future or forward 
contract.  Under the 1997 Act, the entry into a short sale, a swap contract 
or a future or forward contract relating to an appreciated direct position in 
any stock or debt instrument, or the acquisition of stock or debt instrument 
at a time when the Fund occupies an offsetting (short) appreciated position 
in the stock or debt instrument, is treated as a "constructive sale" that 
gives rise to the immediate recognition of gain (but not loss).  The 
application of these

                                      -7-

<PAGE>

new provisions may cause a Fund to recognize taxable income from these 
offsetting transactions in excess of the cash generated by such activities.

     THE TAX DISCUSSION SET FORTH ABOVE IS A SUMMARY INCLUDED FOR GENERAL 
INFORMATION PURPOSES ONLY.  EACH SHAREHOLDER IS ADVISED TO CONSULT ITS OWN 
TAX ADVISER WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES TO IT OF AN 
INVESTMENT IN THE FUNDS, INCLUDING THE EFFECT AND APPLICABILITY OF STATE, 
LOCAL, FOREIGN, AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN 
FEDERAL OR OTHER TAX LAWS. THIS DISCUSSION IS NOT INTENDED AS A SUBSTITUTE 
FOR CAREFUL TAX PLANNING.

                       INVESTMENT ADVISORY AND OTHER SERVICES
                                          
MANAGEMENT CONTRACT

     As disclosed in the Prospectus under the heading "Management of the 
Trust", under management contracts (each, a "Management Contract") between 
the Trust, on behalf of each Fund, and Rosenberg Institutional Equity 
Management (the "Manager"), subject to the control of the Trustees of the 
Trust and such policies as the Trustees may determine, the Manager will 
furnish continuously an investment program for each Fund and will make 
investment decisions on behalf of each Fund and place all orders for the 
purchase and sale of portfolio securities.  Subject to the control of the 
Trustees, the Manager furnishes office space and equipment, provides 
bookkeeping and certain clerical services and pays all salaries, fees and 
expenses of officers and Trustees of the Trust who are affiliated with the 
Manager.  As indicated under "Portfolio Transactions -- Brokerage and 
Research Services," the Trust's portfolio transactions may be placed with 
broker-dealers which furnish the Manager, at no cost, certain research, 
statistical and quotation services of value to the Manager in advising the 
Trust or its other clients.

     As disclosed in the Prospectus, each of the Funds has agreed to pay the 
Manager a quarterly management fee at the annual percentage rate of the 
relevant Fund's average daily net assets set forth in the Prospectus.  The 
Manager has informed the Trust that it will voluntarily waive some or all of 
its management fees under the Management Contracts and, if necessary, will 
bear certain expenses of each Fund until further notice so that each Fund's 
total annual operating expenses (including the management fee but not 
including nonrecurring account fees and extraordinary expenses) applicable to 
each class will not exceed the percentage of each Fund's average daily net 
assets attributable to that class as set forth in the Prospectus.  In 
addition, the Manager's compensation under each Management Contract is 
subject to reduction to the extent that in any year the expenses of a Fund 
(including investment advisory fees but excluding taxes, portfolio brokerage 
commissions and any distribution expenses paid by a class of shares of a Fund 
pursuant to a distribution plan or otherwise) exceed the limits on investment 
company expenses imposed by any statute or regulatory authority of any 
jurisdiction in which shares of the Fund are qualified for offer and sale.

     Each Management Contract provides that the Manager shall not be subject 
to any liability to the Trust or to any shareholder of the Trust in 
connection with the performance of its services thereunder in the absence of 
willful misfeasance, bad faith, gross negligence or reckless disregard of its 
obligations and duties thereunder.

     Each Management Contract will continue in effect for a period of no more 
than two years from the date of its execution only so long as its continuance 
is approved at least annually by (i) vote, cast in person at a meeting called 
for that purpose, of a majority of those Trustees who are not "interested 
persons" of the Manager or the Trust, and by (ii) the majority vote of either 
the full Board of Trustees or the vote of a majority of the outstanding 
shares of the relevant Fund.  Each Management Contract automatically 
terminates on assignment, and is terminable on not more than 60 days' notice 
by the Trust to the Manager. In addition, each Management Contract may be 
terminated on not more than 60 days' written notice by the Manager to the 
Trust.

     As disclosed in the Prospectus, the general partners of the Manager are 
Barr M. Rosenberg, Marlis S. Fritz and Kenneth Reid.  Each of these persons 
may be deemed a controlling person of the Manager.

     As discussed in this Statement of Additional Information under the 
heading "Management of the Trust," Barr M. Rosenberg is a Trustee of the 
Trust as well as Managing General Partner and Chief Investment Officer of the 
Manager; Marlis S. Fritz is a Trustee and Vice President of the Trust as well 
as a general partner of the Manager;

and Kenneth Reid is a Trustee and President of the Trust as well as a general 
partner and Director of Research of the Manager.
   
     During the fiscal period ended March 31, 1998, the Barr Rosenberg Market 
Neutral Fund paid the following amounts as management fees to the Manager 
pursuant to its Management Contract:

ADMINISTRATIVE SERVICES
   
     The Trust has entered into a Fund Administration Agreement with BISYS 
Fund Services (the "Administrator") pursuant to which the Administrator 
provides certain management and administrative services necessary for the 
Funds' operations including: (i) general supervision of the operation of the 
Funds including coordination of the services performed by the Funds' 
investment advisor, transfer agent, custodian, independent accountants and 
legal counsel, regulatory compliance, including the compilation of 
information for documents such as reports to, and filings with, the SEC and 
state securities commissions, and preparation of proxy statements and 
shareholder reports for the Funds; (ii) general supervision relative to the 
compilation of data required for the preparation of periodic reports 
distributed to the Funds' officers and Board of Trustees; and (iii) 
furnishing office space and certain facilities required for conducting the 
business of the Funds.  The Trust's principal underwriter is an affiliate of 
the Administrator.  For these services, the Administrator is entitled to 
receive a fee, payable monthly, at the annual rate of 0.15% of the average 
daily net assets of the Trust.  For the fiscal period ended March 31, 1998 
the Barr Rosenberg Double Alpha Market Fund paid $______ in administration 
fees.  The Trust has also entered into a Fund Accounting Agreement with BISYS 
Fund Services, Inc. (the "Fund Accountant") pursuant to which the Fund 
Accountant provides certain accounting services necessary for the Funds' 
operations.  For these services, the Fund Accountant is entitled to receive 
an annual fee of $40,000 for each Fund.  For the fiscal period ended March 
31, 1998 the Barr Rosenberg Market Neutral Fund paid $______ in fund 
accounting fees. The Trust's principal underwriter is an affiliate of the 
Fund Accountant.
    
DISTRIBUTOR AND DISTRIBUTION PLAN

     As stated in the text of the Prospectus under the heading "Management of 
the Trust -- Distributor", Investor Shares of each Fund are sold on a 
continuous basis by the Trust's distributor, Barr Rosenberg Funds 
Distributor, Inc. (the "Distributor").  Under the Distributor's Contract 
between the Trust and the Distributor (the "Distributor's Contract"), the 
Distributor is not obligated to sell any specific amount of shares of the 
Trust and will purchase shares for resale only against orders for shares.
   
     Pursuant to the Distribution Plan (the "Plan") described in the 
Prospectus, in connection with the distribution of Investor Shares of the 
Trust, the Distributor receives certain distribution fees from the Trust.  
Subject to the percentage limitation on the distribution fee set forth in the 
Prospectus, the distribution fee may be paid in respect of services rendered 
and expenses borne in the past with respect to Investor Shares as to which no 
distribution fee was paid on account of such limitation.  The Distributor may 
pay all or a portion of the distribution fees it receives from the Trust to 
participating and introducing brokers.     The Barr Rosenberg Market Neutral 
Fund paid the Distributor $________ in distribution fees pursuant to the Plan 
for the fiscal year ended March 31, 1998.
    
     The Plan may be terminated with respect to Investor Shares of any Fund 
to which the Plan relates by vote of a majority of the Trustees of the Trust 
who are not interested persons of the Trust (as defined in the 1940 Act) and 
who have no direct or indirect financial interest in the operation of the 
Plan or the Distributor's Contract (the "Independent Trustees"), or by vote 
of a majority of the outstanding voting securities of that class.  Any change 
in the Plan that would materially increase the cost to the Investors Shares 
of any Fund to which the Plan relates requires approval by the Investor 
shareholders of that Fund.  The Trustees of the Trust review quarterly a 
written report of

                                       -11-

<PAGE>

such costs and the purposes for which such costs have been incurred.  Except 
as described above, the Plan may be amended by vote of the Trustees of the 
Trust, including a majority of the Independent Trustees, cast in person at a 
meeting called for the purpose.  For so long as the Plan is in effect, 
selection and nomination of those Trustees of the Trust who are not 
interested persons of the Trust shall be committed to the discretion of such 
disinterested persons.

     The Distributor's Contract may be terminated with respect to any Fund or 
Investor shares thereof at any time by not more than 60 days' nor less than 
30 days' written notice without payment of any penalty either by the 
Distributor or by such Fund or class and will terminate automatically, 
without the payment of any penalty, in the event of its assignment.

     The Distributor's Contract and the Plan will continue in effect with 
respect to each class of shares to which they relate for successive one-year 
periods, provided that each such continuance is specifically approved (i) by 
the vote of a majority of the Independent Trustees and (ii) by the vote of a 
majority of the entire Board of Trustees (or by vote of a majority of the 
outstanding shares of a class, in the case of the Distributor's Contract) 
cast in person at a meeting called for that purpose.

     If the Distributor's Contract or the Plan are terminated (or not 
renewed) with respect to one or more classes, they may continue in effect 
with respect to any class of any Fund as to which they have not been 
terminated (or have been renewed).

     The Trustees of the Trust believe that the Plan will provide benefits to 
the Trust.  The Trustees believe that the Plan will result in greater sales 
and/or fewer redemptions of Investor Shares, although it is impossible to 
know for certain the level of sales and redemptions of Investor Shares that 
would occur in the absence of the Plan or under alternative distribution 
schemes.  The Trustees believe that the effect on sales and/or redemptions 
benefit the Trust by reducing Fund expense ratios and/or by affording greater 
flexibility to Fund managers.

     CUSTODIAL ARRANGEMENTS.  Custodial Trust Company ("CTC"), Princeton, NJ 
08540, is the Trust's custodian.  As such, CTC holds in safekeeping 
certificated securities and cash belonging to the Trust and, in such 
capacity, is the registered owner of securities in book-entry form belonging 
to a Fund.  Upon instruction, CTC receives and delivers cash and securities 
of a Fund in connection with Fund transactions and collects all dividends and 
other distributions made with respect to Fund portfolio securities.

     INDEPENDENT ACCOUNTANTS.  The Trust's independent accountants are Price 
Waterhouse LLP, 160 Federal Street, Boston, Massachusetts 02110.  Price 
Waterhouse LLP conducts an annual audit of the Trust's financial statements, 
assists in the preparation of the Trust's federal and state income tax 
returns and the Trust's filings with the Securities and Exchange Commission, 
and consults with the Trust as to matters of accounting and federal and state 
income taxation.

                               PORTFOLIO TRANSACTIONS

     INVESTMENT DECISIONS.  The purchase and sale of portfolio securities for 
the Funds and for the other investment advisory clients of the Manager are 
made by the Manager with a view to achieving each client's investment 
objective.  For example, a particular security may be purchased or sold on 
behalf of certain clients of the Manager even though it could also have been 
purchased or sold for other clients at the same time.

     Likewise, a particular security may be purchased on behalf of one or 
more clients when the Manager is selling the same security on behalf of one 
or more other clients.  In some instances, therefore, the Manager, acting for 
one client may sell indirectly a particular security to another client.  It 
also happens that two or more clients may simultaneously buy or sell the same 
security, in which event purchases or sales are effected PRO RATA on the 
basis of cash available or other equitable basis so as to avoid any one 
account's being preferred over any other account.

                                       -12-

     BROKERAGE AND RESEARCH SERVICES.  Transactions on stock exchanges and 
other agency transactions involve the payment of negotiated brokerage 
commissions. Such commissions vary among different brokers.  There is 
generally no stated commission in the case of securities traded in the 
over-the-counter markets, but the price paid for such securities usually 
includes an undisclosed dealer commission or mark up.  In placing orders for 
the portfolio transactions of a Fund, the Manager will seek the best price 
and execution available, except to the extent it may be permitted to pay 
higher brokerage commissions for brokerage and research services as described 
below.  The determination of what may constitute best price and execution by 
a broker-dealer in effecting a securities transaction involves a number of 
considerations, including, without limitation, the overall net economic 
result to the Fund (involving price paid or received and any commissions and 
other costs paid), the efficiency with which the transaction is effected, the 
ability to effect the transaction at all where a large block is involved, 
availability of the broker to stand ready to execute possibly difficult 
transactions in the future and the financial strength and stability of the 
broker.  Because of such factors, a broker-dealer effecting a transaction may 
be paid a commission higher than that charged by another broker-dealer.  Most 
of the foregoing are judgmental considerations.

     Over-the-counter transactions often involve dealers acting for their own 
account.  It is the Manager's policy to place over-the-counter market orders 
for a Fund with primary market makers unless better prices or executions are 
available elsewhere.

     Although the Manager does not consider the receipt of research services 
as a factor in selecting brokers to effect portfolio transactions for a Fund, 
the Manager will receive such services from brokers who are expected to 
handle a substantial amount of a Fund's portfolio transactions.  Research 
services may include a wide variety of analyses, reviews and reports on such 
matters as economic and political developments, industries, companies, 
securities and portfolio strategy.  The Manager uses such research in 
servicing other clients as well as the Trust.

     As permitted by Section 28(e) of the Securities Exchange Act of 1934, as 
amended, and subject to such policies as the Trustees of the Trust may 
determine, the Manager may pay an unaffiliated broker or dealer that provides 
"brokerage and research services" (as defined in the Act) to the Manager an 
amount of commission for effecting a portfolio investment transaction in 
excess of the amount of commission another broker or dealer would have 
charged for effecting that transaction.

     The Barr Rosenberg Market Neutral Fund paid brokerage commissions of 
$_______ for the fiscal year ended March 31, 1998.

                             TOTAL RETURN CALCULATIONS

     Each Fund computes its cumulative total return separately for its share 
classes by determining the cumulative rates of return during specified 
periods that would equate the initial amount invested in a particular share 
class to the ending redeemable value of such investment in such class, 
according to the following formula:

Where:                               n
                               P(1 + T) = ERV

     T    =            Average annual total return
     ERV  =    Ending redeemable value of a hypothetical $1,000 payment made
               at the beginning of a period at the end of such period
     P    =    A hypothetical initial payment of $1,000
     n    =    Number of years

     Each Fund computes its cumulative total return separately for its share 
classes by determining the cumulative rates of return during specified 
periods that would equate the initial amount invested in a particular share 
class to the ending redeemable value of such investment in such class, 
according to the following formula:

Where:                   T = ERV-1,000
                         -------------
                             1,000

Where:
     T    =    Cumulative rate of return
     ERV  =    Ending redeemable value of a hypothetical $1,000 investment made
               at the beginning of a period at the end of such period.
    
   
     The calculations of average annual total return and cumulative total 
returns assume that any dividends and distributions are reinvested 
immediately, rather than paid to the investor in cash.  The ending redeemable 
value (variable "ERV" in each formula) is determined by assuming complete 
redemption of the hypothetical investment and the deduction of all 
nonrecurring charges at the end of the period covered by the computations.
    
     Unlike bank deposits or other investments that pay a fixed yield or 
return for a stated period of time, the return for each Fund will fluctuate 
from time to time and does not provide a basis for determining future 
returns.  Average annual total return is based on many factors, including 
market conditions, the composition of a Fund's portfolio and a Fund's 
operating expenses.

     Average annual total return is calculated separately for Investor Shares 
and Institutional Shares.  Investor Shares and Institutional Shares are 
subject to different fees and expenses and may have different performance for 
the same period.
   
     The cumulative return of the Barr Rosenberg Market Neutral Fund for the 
period ended March 31, 1998 is as follows:

hypothetical compounding examples, which describe hypothetical investment 
results in such communications.  Such performance examples will be based on 
an express set of assumptions and are not indicative of the performance of a 
Fund.

                  DESCRIPTION OF THE TRUST AND OWNERSHIP OF SHARES

     As more fully described in the Prospectus, the Trust is a diversified 
open-end series investment company organized as a Massachusetts business 
trust. A copy of the Agreement and Declaration of Trust of the Trust, as 
amended (the "Declaration of Trust"), is on file with the Secretary of The 
Commonwealth of Massachusetts.  The fiscal year of the Trust ends on March 
31.  The Trust changed its name to "Barr Rosenberg Series Trust" from 
"Rosenberg Series Trust" on August 5, 1996.

     Interests in the Trust's portfolios are currently represented by shares 
of five series, the Barr Rosenberg Market Neutral Fund, Barr Rosenberg Double 
Alpha Market Fund, U.S. Small Capitalization Series, International Small 
Capitalization Series and Japan Series, issued pursuant to the Declaration of 
Trust.  The rights of shareholders and powers of the Trustees of the Trust 
with respect to such shares are described in the Prospectus.

     As described in the Prospectus, each Fund is further divided into two 
classes of shares designated as Institutional Shares and Investor Shares.  
Each class of shares of each Fund represents interests in the assets of the 
Fund and has identical dividend, liquidation and other rights and the same 
terms and conditions except that expenses, if any, related to the 
distribution and shareholder servicing of a particular class are borne solely 
by such class and each class may, at the discretion of the Trustees of the 
Trust, also pay a different share of other expenses, not including advisory 
or custodial fees or other expenses related to the management of the Trust's 
assets, if these expenses are actually incurred in a different amount by that 
class, or if the class receives services of a different kind or to a 
different degree than the other classes.  All other expenses are allocated to 
each class on the basis of the net asset value of that class in relation to 
the net asset value of the particular Fund.

     The Declaration of Trust provides for the perpetual existence of the 
Trust. The Trust may, however, be terminated at any time by vote of at least 
two-thirds of the outstanding shares of the Trust.

VOTING RIGHTS

     Shareholders are entitled to one vote for each full share held (with 
fractional votes for fractional shares held) and will vote (to the extent 
provided herein) in the election of Trustees and the termination of the Trust 
and on other matters submitted to the vote of shareholders.  Shareholders 
will vote by individual Fund on all matters except (i) when required by the 
1940 Act, shares shall be voted in the aggregate and not by individual Fund, 
and (ii) when the Trustees have determined that the matter affects only the 
interests of one or more Funds, then only shareholders of such Funds shall be 
entitled to vote thereon.  Shareholders of one Fund shall not be entitled to 
vote on matters exclusively affecting another Fund, such matters including, 
without limitation, the adoption of or change in any fundamental policies or 
restrictions of the other Fund and the approval of the investment advisory 
contracts of the other Fund.

     Each class of shares of each Fund has identical voting rights except 
that each class has exclusive voting rights on any matter submitted to 
shareholders that relates solely to that class, and has separate voting 
rights on any matter submitted to shareholders in which the interests of one 
class differ from the interests of any other class.  Each class

                                       -15-

<PAGE>

of shares has exclusive voting rights with respect to matters pertaining to 
any distribution or servicing plan applicable to that class.  All classes of 
shares of a Fund will vote together, except with respect to any distribution 
or servicing plan applicable to a class or when a class vote is required as 
specified above or otherwise by the 1940 Act.

     There will normally be no meetings of shareholders for the purpose of 
electing Trustees, except that in accordance with the 1940 Act (i) the Trust 
will hold a shareholders' meeting for the election of Trustees at such time 
as less than a majority of the Trustees holding office have been elected by 
shareholders, and (ii) if, as a result of a vacancy in the Board of Trustees, 
less than two-thirds of the Trustees holding office have been elected by the 
shareholders, that vacancy may only be filled by a vote of the shareholders.  
In addition, Trustees may be removed from office by a written consent signed 
by the holders of two-thirds of the outstanding shares and filed with the 
Trust's custodian or by a vote of the holders of two-thirds of the 
outstanding shares at a meeting duly called for the purpose, which meeting 
shall be held upon the written request of the holders of not less than 10% of 
the outstanding shares. Upon written request by the holders of at least 1% of 
the outstanding shares stating that such shareholders wish to communicate 
with the other shareholders for the purpose of obtaining the signatures 
necessary to demand a meeting to consider removal of a Trustee, the Trust has 
undertaken to provide a list of shareholders or to disseminate appropriate 
materials (at the expense of the requesting shareholders).  Except as set 
forth above, the Trustees shall continue to hold office and may appoint 
successor Trustees.  Voting rights are not cumulative.

     No amendment may be made to the Declaration of Trust without the 
affirmative vote of a majority of the outstanding shares of the Trust except 
(i) to change the Trust's name or to cure technical problems in the 
Declaration of Trust and (ii) to establish, designate or modify new and 
existing series, sub-series or classes of shares of any series of Trust 
shares or other provisions relating to Trust shares in response to applicable 
laws or regulations.

SHAREHOLDER AND TRUSTEE LIABILITY

     Under Massachusetts law, shareholders could, under certain 
circumstances, be held personally liable for the obligations of the Trust.  
However, the Declaration of Trust disclaims shareholder liability for acts or 
obligations of the Trust and requires that notice of such disclaimer be given 
in each agreement, obligation, or instrument entered into or executed by the 
Trust or the Trustees.  The Declaration of Trust provides for indemnification 
out of all the property of the relevant Fund for all loss and expense of any 
shareholder of that Fund held personally liable for the obligations of the 
Trust.  Thus, the risk of a shareholder incurring financial loss on account 
of shareholder liability is considered remote since it is limited to 
circumstances in which the disclaimer is inoperative and the Fund of which he 
is or was a shareholder would be unable to meet its obligations.

     The Declaration of Trust further provides that the Trustees will not be 
liable for errors of judgment or mistakes of fact or law.  However, nothing 
in the Declaration of Trust protects a Trustee against any liability to which 
the Trustee would otherwise be subject by reason of willful misfeasance, bad 
faith, gross negligence, or reckless disregard of the duties involved in the 
conduct of his office.  The Declaration of Trust also provides for 
indemnification by the Trust of the Trustees and the officers of the Trust 
against liabilities and expenses reasonably incurred in connection with 
litigation in which they may be involved because of their offices with the 
Trust, except if it is determined in the manner specified in the Declaration 
of Trust that such Trustees are liable to the Trust or its shareholders by 
reason of willful misfeasance, bad faith, gross negligence or reckless 
disregard of his or her duties.  In addition, the Manager has agreed to 
indemnify each Trustee who is not "an interested person" of the Trust to the 
maximum extent permitted by the 1940 Act against any liabilities arising by 
reason of such Trustee's status as a Trustee of the Trust.

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

     The officers and trustees of the Trust, as a group, own less than 1% of 
any class of outstanding shares of the Trust.

                          DETERMINATION OF NET ASSET VALUE

     As indicated in the Prospectus, the net asset value of each Fund share 
is determined on each day on which the New York Stock Exchange is open for 
trading. The Trust expects that the days, other than weekend days, that the 
New York Stock Exchange will not be open are Christmas Day, New Year's Day, 
Martin Luther King's Day, President's Day, Good Friday and Memorial Day, 
Independence Day (observed), Labor Day and Thanksgiving Day.

     Portfolio securities listed on a securities exchange for which market 
quotations are available are valued at the last quoted sale price on each 
business day, or, if there is no such reported sale, at the most recent 
quoted bid price.  Price information on listed securities is generally taken 
from the closing price on the exchange where the security is primarily 
traded.  Unlisted securities for which market quotations are readily 
available are valued at the most recent quoted bid price, except that debt 
obligations with sixty days or less remaining until maturity may be valued at 
their amortized cost. Exchange-traded options, futures and options on futures 
are valued at the settlement price as determined by the appropriate clearing 
corporation.  Other assets and securities for which no quotations are readily 
available are valued at fair value as determined in good faith by the 
Trustees of the Trust or by persons acting at their direction.

                         PURCHASE AND REDEMPTION OF SHARES

     The procedures for purchasing shares of each of the Funds and for 
determining the offering price of such shares are described in the 
Prospectus. The Trust has elected to be governed by Rule 18f-1 under the 1940 
Act pursuant to which the Trust is obligated to redeem shares solely in cash 
for any shareholder during any 90-day period up to the lesser of (i) $250,000 
or (ii) 1% of the total net asset value of the Trust at the beginning of such 
period.  The procedures for redeeming shares of each of the Funds are 
described in the Prospectus.

     This Statement of Additional Information is not a prospectus.  This 
Statement of Additional Information relates to the prospectus of the Barr 
Rosenberg Market Neutral Fund and Barr Rosenberg Double Alpha Market Fund of 
Barr Rosenberg Series Trust dated July __, 1998 (the "Prospectus") and should

                         INVESTMENT OBJECTIVES AND POLICIES

     The investment objective and policies of each of the Barr Rosenberg 
Market Neutral Fund and Barr Rosenberg Double Alpha Market Fund (each, a 
"Fund" and collectively, the "Funds") of Barr Rosenberg Series Trust (the 
"Trust") are summarized on the front page of the Prospectus and in the text 
of the Prospectus under the headings "Investment Objectives and Policies" and 
"General Description of Risks and Fund Investments."

     In addition, the following is an additional description of certain 
investments of the Fund(s).

     SHORT SALES (BOTH FUNDS).  The Barr Rosenberg Market Neutral Fund will 
seek, and the Barr Rosenberg Double Alpha Market Fund may seek, to realize 
additional gains through short sales.  Short sales are transactions in which 
a Fund sells a security it does not own, in anticipation of a decline in the 
value of that security relative to the long positions held by the Fund.  To 
complete such a transaction, a Fund must borrow the security to make delivery 
to the buyer.  A Fund then is obligated to replace the security borrowed by 
purchasing it at the market price at or prior to the time of replacement.  
The price at such time may be more or less than the price at which the 
security was sold by a Fund.  Until the security is replaced, a Fund is 
required to repay the lender any dividends or interest that accrue during the 
period of the loan.  To borrow the security, a Fund also may be required to 
pay a premium, which would increase the cost of the security sold.  The net 
proceeds of the short sale will be retained by the broker (or by the Fund's 
custodian in a special custody account), to the extent necessary to meet 
margin requirements, until the short position is closed out.  A Fund also 
will incur transaction costs in effecting short sales.

A Fund will incur a loss as a result of the short sale if the price of the 
security increases between the date of the short sale and the date on which 
the Fund replaces the borrowed security.  A Fund will realize a gain if the 
security declines in price between those dates.  The amount of any gain will 
be decreased, and the amount of any loss increased, by the amount of the 
premium, dividends, interest or expenses a Fund may be required to pay in 
connection with a short sale.  An increase in the value of a security sold 
short by a Fund over the price at which it was sold short will result in a 
loss to the Fund, and there can be no assurance that the Fund will be able to 
close out the position at any particular time or at an acceptable price.

     S&P 500 INDEX FUTURES AND RELATED OPTIONS (BARR ROSENBERG DOUBLE ALPHA 
MARKET FUND ONLY).  An S&P 500 Index Future contract (an "Index Future") is a 
contract to buy or sell an integral number of units of the Standard & Poor's 
500 Composite Stock Price Index (the "S&P 500 Index") at a specified future 
date at a price agreed upon when the contract is made.  A unit is the value 
of the S&P 500 Index from time to time.  Entering into a contract to buy 
units is commonly referred to as buying or purchasing a contract or holding a 
long position in the S&P 500 Index.

     Index Futures can be traded through all major commodity brokers. 
Currently, contracts are expected to expire on the tenth day of March, June, 
September and December.  The Barr Rosenberg Double Alpha Market Fund will 
ordinarily be able to close open positions on the United States futures 
exchange on which Index Futures are then traded at any time up to and 
including the expiration day.

     In contrast to purchases of a common stock, no price is paid or received 
by the Barr Rosenberg Double Alpha Market Fund upon the purchase of a futures 
contract.  Upon entering into a futures contract, the Fund will be required 
to deposit with its custodian in a segregated account in the name of the 
futures broker a specified amount of cash or securities.  This is known by 
participants in the market as "initial margin".  The type of instruments that 
may be deposited as initial margin, and the required amount of initial 
margin, are determined by the futures exchange(s) on which the Index Futures 
are traded. The nature of initial margin in futures transactions is different 
from that of margin in securities transactions in that futures contract 
margin does not involve the borrowing of funds by the customer to finance the 
transactions. Rather, the initial margin is in the nature of a performance 
bond or good faith deposit on the contract which is returned to the Fund upon 
termination of the futures contract, assuming all contractual obligations 
have been satisfied. Subsequent payments, called "variation margin", to and 
from the broker, will be
    

                                      -3-

<PAGE>

   
made on a daily basis as the price of the S&P 500 Index fluctuates, making 
the position in the futures contract more or less valuable, a process known 
as "marking to the market".  For example, when the Fund has purchased an 
Index Future and the price of the S&P 500 Index has risen, that position will 
have increased in value and the Fund will receive from the broker a variation 
margin payment equal to that increase in value.  Conversely, when the Fund 
has purchased an Index Future and the price of the S&P 500 Index has 
declined, the position would be less valuable and the Fund would be required 
to make a variation margin payment to the broker.  When the Fund terminates a 
position in a futures contract, a final determination of variation margin is 
made, additional cash is paid by or to the Fund, and the Fund realizes a gain 
or a loss.

     The price of Index Futures may not correlate perfectly with movement in 
the underlying index due to certain market distortions.  First, all 
participants in the futures market are subject to margin deposit and 
maintenance requirements. Rather than meeting additional margin deposit 
requirements, investors may close futures contracts through offsetting 
transactions which could distort the normal relationship between the S&P 500 
Index and futures markets.  Secondly, the deposit requirements in the futures 
market are less onerous than margin requirements in the securities market, 
and as a result the futures market may attract more speculators than does the 
securities market.  Increased participation by speculators in the futures 
market may also cause temporary price distortions.

     Options on index futures contracts give the purchaser the right, in 
return for the premium paid, to assume a position in an index futures 
contract (a long position if the option is a call and a short position if the 
option is a put) at a specified exercise price at any time during the period 
of the option.  Upon exercise of the option, the holder would assume the 
underlying futures position and would receive a variation margin payment of 
cash or securities approximating the increase in the value of the holder's 
option position.  If an option is exercised on the last trading day prior to 
the expiration date of the option, the settlement will be made entirely in 
cash based on the difference between the exercise price of the option and the 
closing level of the index on which the futures contract is based on the 
expiration date.  Purchasers of options who fail to exercise their options 
prior to the exercise date suffer a loss of the premium paid.

     The ability to establish and close out positions in options on futures 
contracts will be subject to the development and maintenance of a liquid 
secondary market.  It is not certain that such a market will develop.  
Although the Barr Rosenberg Double Alpha Market Fund generally will purchase 
only those options for which there appears to be an active secondary market, 
there is no assurance that a liquid secondary market on an exchange will 
exist for any particular option or at any particular time.  In the event no 
such market exists for particular options, it might not be possible to effect 
closing transactions in such options, with the result that the Fund would 
have to exercise the options in order to realize any profit.

                         MISCELLANEOUS INVESTMENT PRACTICES

     PORTFOLIO TURNOVER.  A change in securities held by a Fund is known as 
"portfolio turnover" and almost always involves the payment by a Fund of 
brokerage commissions or dealer markup and other transaction costs on the 
sale of securities as well as on the reinvestment of the proceeds in other 
securities.  Portfolio turnover is not a limiting factor with respect to 
investment decisions.  As disclosed in the Prospectus, high portfolio 
turnover involves correspondingly greater brokerage commissions and other 
transaction costs, which will be borne directly by the Funds, and could 
involve realization of capital gains that would be taxable when distributed 
to shareholders of a Fund.  To the extent that portfolio turnover results in 
the realization of net short-term capital gains, such gains are ordinarily 
taxed to shareholders at ordinary income tax rates.  See "Portfolio 
Transactions" and "Income Dividends, Distributions and Tax Status".

     NOTICE ON SHAREHOLDER APPROVAL.  Unless otherwise indicated in the 
Prospectus or this Statement of Additional Information, the investment 
objective and policies of each of the Funds may be changed without 
shareholder approval.

                            INVESTMENT RESTRICTIONS

     Without a vote of the majority of the outstanding voting securities of a 
Fund, the Trust will not take any of the following actions with respect to 
such Fund:

     (1)  Borrow money in excess of 10% of the value (taken at the lower of 
cost or current value) of the Fund's total assets (not including the amount 
borrowed) at the time the borrowing is made, and then only from banks as a 
temporary measure to facilitate the meeting of redemption requests (not for 
leverage) which might otherwise require the untimely disposition of portfolio 
investments or for extraordinary or emergency purposes or for payments of 
variation margin (in the case of the Barr Rosenberg Double Alpha Market Fund 
only).  Such borrowings will be repaid before any additional investments are 
purchased. Short sales and related borrowings of securities are not subject 
to this restriction.

     (2)  Pledge, hypothecate, mortgage or otherwise encumber its assets in 
excess of 10% of the Fund's total assets (taken at cost) and then only to 
secure borrowings permitted by Restriction 1 above.  (For the purposes of 
this restriction, collateral arrangements with respect to options, short 
sales, stock index, interest rate, currency or other futures, options on 
futures contracts and collateral arrangements with respect to initial and 
variation margin are not deemed to be a pledge or other encumbrance of 
assets.  Collateral arrangements with respect to swaps and other derivatives 
are also not deemed to be a pledge or other encumbrance of assets.)

     (3)  Purchase securities on margin, except such short-term credits as 
may be necessary for the clearance of purchases and sales of securities.  
(For this purpose, the deposit or payment of initial or variation margin in 
connection with futures contracts or related options transactions is not 
considered the purchase of a security on margin.)

     (4)  Make short sales of securities or maintain a short position if, 
when added together, more than 100% of the value of a Fund's net assets would 
be (i) deposited as collateral for the obligation to replace securities 
borrowed to effect short sales, and (ii) allocated to segregated accounts in 
connection with short sales.  Short sales "against the box" are not subject 
to this limitation.

     (5)  Underwrite securities issued by other persons except to the extent 
that, in connection with the disposition of its portfolio investments, it may 
be deemed to be an underwriter under federal securities laws.

     (6)  Purchase or sell real estate, although it may purchase securities 
of issuers which deal in real estate, including securities of real estate 
investment trusts, and may purchase securities which are secured by interests 
in real estate.

     (7)  Concentrate more than 25% of the value of its total assets in any 
one industry.

     (8)  Invest in securities of other investment companies, except to the 
extent permitted by the Investment Company Act of 1940, as amended (the "1940 
Act"), or by an exemptive order issued by the Securities and Exchange 
Commission.

     (9)  Purchase or sell commodities or commodity contracts except that 
each of the Funds may purchase and sell stock index and other financial 
futures contracts and options thereon.

     (10) Make loans, except by purchase of debt obligations or by entering 
into repurchase agreements or through the lending of the Fund's portfolio 
securities.

     (11) Issue senior securities.  (For the purpose of this restriction none 
of the following is deemed to be a senior security: any pledge or other 
encumbrance of assets permitted by restriction (2) above; any borrowing
    


                                      -5-

<PAGE>
   
permitted by restriction (1) above; short sales permitted by restriction (4) 
above; any collateral arrangements with respect to short sales, swaps, 
options, future contracts and options on future contracts and with respect to 
initial and variation margin; and the purchase or sale of options, future 
contracts or options on future contracts.)

     Notwithstanding the latitude permitted by Restriction 9 above, the Funds 
have no current intention of purchasing interest rate futures.

     It is contrary to the present policy of each of the Funds, which may be 
changed by the Trustees of the Trust without shareholder approval, to:

     (a)  Invest in warrants or rights (other than warrants or rights 
acquired by the Fund as a part of a unit or attached to securities at the 
time of purchase).

     (b)  Write, purchase or sell options on particular securities (as 
opposed to market indices).

     (c)  Buy or sell oil, gas or other mineral leases, rights or royalty 
contracts.

     (d)  Make investments for the purpose of exercising control of a 
company's management.

     (e)  Invest in (a) securities which at the time of investment are not 
readily marketable and (b) repurchase agreements maturing in more than seven 
days if, as a result, more than 15% of the Fund's net assets (taken at 
current value) would then be invested in such securities.

     Unless otherwise indicated, all percentage limitations on investments 
set forth herein and in the Prospectus will apply at the time of the making 
of an investment and shall not be considered violated unless an excess or 
deficiency occurs or exists immediately after and as a result of such 
investment.

     The phrase "shareholder approval," as used in the Prospectus and herein, 
and the phrase "vote of a majority of the outstanding voting securities", as 
used herein, means the affirmative vote of the lesser of (1) more than 50% of 
the outstanding shares of a Fund or the Trust, as the case may be, or (2) 67% 
or more of the shares of a Fund or the Trust, as the case may be, present at 
a meeting if more than 50% of the outstanding shares are represented at the 
meeting in person or by proxy.

                   INCOME DIVIDENDS, DISTRIBUTIONS AND TAX STATUS

     The tax status of the Funds and the distributions which they may make 
are summarized in the Prospectus under the heading "Taxes."  The Funds intend 
to qualify each year as a regulated investment company under the Internal 
Revenue Code.  In order to qualify as a "regulated investment company" and to 
qualify for the special tax treatment accorded regulated investment companies 
and their shareholders, each Fund must, among other things, (a) derive at 
least 90% of its gross income from dividends, interest, payments with respect 
to certain securities loans, gains from the sale or other disposition of 
securities or foreign currencies or other income (including but not limited 
to gains from options, futures or forward contracts) derived with respect to 
its business of investing in such securities or currencies; (b) diversify its 
holdings so that, at the close of each quarter of its taxable year, (i) at 
least 50% of the value of its total assets consists of cash, cash items, U.S. 
Government securities, securities of other regulated investment companies, 
and other securities limited generally with respect to any one issuer to not 
more than 5% of the total assets of such Fund and not more than 10% of the 
outstanding voting securities of such issuer, and (ii) not more than 25% of 
the value of its total assets is invested in the securities of any issuer 
(other than U.S. Government securities or securities of other regulated 
investment companies); and (c) distribute annually at least 90% of the sum of 
its taxable net investment income, its net tax-exempt income (if any), and, 
the excess, if any, of net short-term capital gains over net long-term 
capital losses for such year.  To the extent a Fund qualifies for treatment 
as a
    


                                      -6-

<PAGE>

   
regulated investment company, the Fund will not be subject to federal income 
tax on income paid to its shareholders in the form of dividends or capital 
gain distributions.

     As described in the Prospectus under the heading "Distributions," each 
Fund intends to pay out substantially all of its ordinary income and net 
short-term capital gains, and to distribute substantially all of its net 
capital gains, if any, after giving effect to any available capital loss 
carryover.  Net capital gain is the excess of net gains from assets held for 
more than one year over net losses from capital assets held for not more than 
one year.  In order to avoid an excise tax imposed on certain undistributed 
income, a Fund must distribute prior to each calendar year end without regard 
to the Fund's fiscal year end (i) 98% of the Fund's ordinary income, and (ii) 
98% of the Fund's capital gain net income, if any, realized in the one-year 
period ending on October 31.

     In general, all dividend distributions derived from ordinary income and 
short-term capital gain are taxable to investors as ordinary income (eligible 
in part for the dividends-received deduction in the case of corporations, 
subject to certain conditions).  Pursuant to the Taxpayer Relief Act of 1997 
(the "1997 Act"), two different tax rates apply to net capital gains.  One 
rate (generally 28%) applies to net gains on capital assets held for more 
than one year but not more than 18 months ("mid-term gains") and a second, 
preferred rate (generally 20%) applies to the balance of such net capital 
gains ("adjusted net capital gains").  Distributions of net capital gains 
will be treated in the hands of shareholders as mid-term gains to the extent 
designated by the Fund as deriving from net gains from assets held for more 
than one year but not more than 18 months, and the balance will be treated as 
adjusted net capital gains. Distributions of mid-term gains and adjusted net 
capital gains will be taxable to shareholders as such, regardless of how long 
a shareholder has held the shares in the Fund.  Distributions will be taxable 
as described above whether received in cash or in shares through the 
reinvestment of distributions.  The dividends-received deduction for 
corporations will generally apply to a Fund's dividends from investment 
income to the extent derived from dividends received by the Fund from 
domestic corporations, provided the Fund and the shareholder each meet the 
relevant holding period requirements.

     Certain tax exempt organizations or entities may not be subject to 
federal income tax on dividends or distributions from a Fund.  Each 
organization or entity should review its own circumstances and the federal 
tax treatment of its income.

     Each Fund is generally required to withhold and remit to the U.S. 
Treasury 31% of the taxable dividends and other distributions, whether 
distributed in cash or reinvested in shares of the Fund, paid or credited to 
any shareholder account for which an incorrect or no taxpayer identification 
number has been provided or where the Fund is notified that the shareholder 
has underreported income in the past (or the shareholder fails to certify 
that he is not subject to such withholding).  However, the general back-up 
withholding rules set forth above will not apply to tax exempt entities so 
long as each such entity furnishes a Fund with an appropriate certificate.

     To the extent such investments are permissible for a particular Fund, 
the Fund's transactions in options, futures contracts, hedging transactions, 
forward contracts and straddles will be subject to special tax rules 
(including mark-to-market, constructive sale, straddle, wash sale and short 
sale rules), the effect of which may be to accelerate income to the Fund, 
defer losses to the Fund, cause adjustments in the holding periods of the 
Fund's securities and convert short-term capital losses into long-term 
capital losses.  These rules could therefore affect the amount, timing and 
character of distributions to shareholders.

     Pursuant to the 1997 Act, new "constructive sale" provisions apply to 
activities by a Fund which lock in gain on an "appreciated financial 
position." Generally, a "position" is defined to include stock, a debt 
instrument, or partnership interest, or an interest in any of the foregoing, 
including through a short sale, a swap contract, or a future or forward 
contract.  Under the 1997 Act, the entry into a short sale, a swap contract 
or a future or forward contract relating to an appreciated direct position in 
any stock or debt instrument, or the acquisition of stock or debt instrument 
at a time when the Fund occupies an offsetting (short) appreciated position 
in the stock or debt instrument, is treated as a "constructive sale" that 
gives rise to the immediate recognition of gain (but not loss).  The 
application of these
    

                                      -7-

<PAGE>
   
new provisions may cause a Fund to recognize taxable income from these 
offsetting transactions in excess of the cash generated by such activities.

     THE TAX DISCUSSION SET FORTH ABOVE IS A SUMMARY INCLUDED FOR GENERAL 
INFORMATION PURPOSES ONLY.  EACH SHAREHOLDER IS ADVISED TO CONSULT ITS OWN 
TAX ADVISER WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES TO IT OF AN 
INVESTMENT IN THE FUNDS, INCLUDING THE EFFECT AND APPLICABILITY OF STATE, 
LOCAL, FOREIGN, AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN 
FEDERAL OR OTHER TAX LAWS. THIS DISCUSSION IS NOT INTENDED AS A SUBSTITUTE 
FOR CAREFUL TAX PLANNING.

     Messrs.  Rosenberg, Reid, Arbit, Lyman and Saalfeld and Ms. Fritz, 
Demler and Hew, each being a general partner, limited partner, officer or 
employee of the Manager, will each benefit from the management fees paid by 
the Trust to the Manager, but receive no direct compensation from the Trust.

                       INVESTMENT ADVISORY AND OTHER SERVICES

     MANAGEMENT CONTRACT.  As disclosed in the Prospectus under the heading 
"Management of the Trust", under management contracts (each, a "Management 
Contract") between the Trust, on behalf of each Fund, and Rosenberg 
Institutional Equity Management (the "Manager"), subject to the control of 
the Trustees of the Trust and such policies as the Trustees may determine, 
the Manager will furnish continuously an investment program for each Fund and 
will make investment decisions on behalf of each Fund and place all orders 
for the purchase and sale of portfolio securities.  Subject to the control of 
the Trustees, the Manager furnishes office space and equipment, provides 
bookkeeping and certain clerical services and pays all salaries, fees and 
expenses of officers and Trustees of the Trust who are affiliated with the 
Manager.  As indicated under "Portfolio Transactions -- Brokerage and 
Research Services," the Trust's portfolio transactions may be placed with 
broker-dealers which furnish the Manager, at no cost, certain research, 
statistical and quotation services of value to the Manager in advising the 
Trust or its other clients.

     As disclosed in the Prospectus, each of the Funds has agreed to pay the 
Manager a quarterly management fee at the annual percentage rate of the 
relevant Fund's average daily net assets set forth in the Prospectus.  The 
Manager has informed the Trust that it will voluntarily waive some or all of 
its management fees under the Management Contracts and, if necessary, will 
bear certain expenses of each Fund until further notice so that each Fund's 
total annual operating expenses (including the management fee but not 
including nonrecurring account fees and extraordinary expenses) applicable to 
each class will not exceed the percentage of each Fund's average daily net 
assets attributable to that class as set forth in the Prospectus.  In 
addition, the Manager's compensation under each Management Contract is 
subject to reduction to the extent that in any year the expenses of a Fund 
(including investment advisory fees but excluding taxes, portfolio brokerage 
commissions and any distribution expenses paid by a class of shares of a Fund 
pursuant to a distribution plan or otherwise) exceed the limits on investment 
company expenses imposed by any statute or regulatory authority of any 
jurisdiction in which shares of the Fund are qualified for offer and sale.

     Each Management Contract provides that the Manager shall not be subject 
to any liability to the Trust or to any shareholder of the Trust in 
connection with the performance of its services thereunder in the absence of 
willful misfeasance, bad faith, gross negligence or reckless disregard of its 
obligations and duties thereunder.

     Each Management Contract will continue in effect for a period of no more 
than two years from the date of its execution only so long as its continuance 
is approved at least annually by (i) vote, cast in person at a meeting called 
for that purpose, of a majority of those Trustees who are not "interested 
persons" of the Manager or the Trust, and by (ii) the majority vote of either 
the full Board of Trustees or the vote of a majority of the outstanding 
shares of the relevant Fund.  Each Management Contract automatically 
terminates on assignment, and is terminable on not more than 60 days' notice 
by the Trust to the Manager. In addition, each Management Contract may be 
terminated on not more than 60 days' written notice by the Manager to the 
Trust.

     As disclosed in the Prospectus, the general partners of the Manager are 
Barr M. Rosenberg, Marlis S. Fritz and Kenneth Reid.  Each of these persons 
may be deemed a controlling person of the Manager.

     As discussed in this Statement of Additional Information under the 
heading "Management of the Trust," Barr M. Rosenberg is a Trustee of the 
Trust as well as Managing General Partner and Chief Investment Officer of the 
Manager; Marlis S. Fritz is a Trustee and Vice President of the Trust as well 
as a general partner of the Manager; and Kenneth Reid is a Trustee and 
President of the Trust as well as a general partner and Director of Research 
of the Manager.

     During the fiscal period ended March 31, 1998, the Barr Rosenberg Market 
Neutral Fund paid the following amounts as management fees to the Manager 
pursuant to its Management Contract:

                                        Gross     Reduction     Net
12/16/97 - 3/31/98

     ADMINISTRATIVE SERVICES.  The Trust has entered into a Fund 
Administration Agreement with BISYS Fund Services (the "Administrator") 
pursuant to which the Administrator provides certain management and 
administrative services necessary for the Funds' operations including: (i) 
general supervision of the operation of the Funds including coordination of 
the services performed by the Funds' investment advisor, transfer agent, 
custodian, independent accountants and legal counsel, regulatory compliance, 
including the compilation of information for documents such as reports to, 
and filings with, the SEC and state securities commissions, and preparation 
of proxy statements and shareholder reports for the Funds; (ii) general 
supervision relative to the compilation of data required for the preparation 
of periodic reports distributed to the Funds' officers and Board of Trustees; 
and (iii) furnishing office space and certain facilities required for 
conducting the business of the Funds.  The Trust's principal underwriter is 
an affiliate of the Administrator.  For these services, the Administrator is 
entitled to receive a fee, payable monthly, at the annual rate of 0.15% of 
the average daily net assets of the Trust.  For the fiscal period ended March 
31, 1998 the Barr Rosenberg Double Alpha Market Fund paid $_____ in 
administration fees.  The Trust has also entered into a Fund Accounting 
Agreement with BISYS Fund Services, Inc. (the "Fund Accountant") pursuant to 
which the Fund Accountant provides certain accounting services necessary for 
the Funds' operations.  For these services, the Fund Accountant is entitled 
to receive an annual fee of $40,000 for each Fund.  For the fiscal period 
ended March 31, 1998 the Barr Rosenberg Market Neutral Fund paid $______ in 
fund accounting fees. The Trust's principal underwriter is an affiliate of 
the Fund Accountant.

     DISTRIBUTOR AND DISTRIBUTION PLAN.  As stated in the text of the 
Prospectus under the heading "Management of the Trust -- Distributor", 
Investor Shares of each Fund are sold on a continuous basis by the Trust's 
distributor, Barr Rosenberg Funds Distributor, Inc. (the "Distributor").  
Under the Distributor's Contract between the Trust and the Distributor (the 
"Distributor's Contract"), the Distributor is not obligated to sell any 
specific amount of shares of the Trust and will purchase shares for resale 
only against orders for shares.

     Pursuant to the Distribution Plan (the "Plan") described in the 
Prospectus, in connection with the distribution of Investor Shares of the 
Trust, the Distributor receives certain distribution fees from the Trust.  
Subject to the percentage limitation on the distribution fee set forth in the 
Prospectus, the distribution fee may be paid in respect of services rendered 
and expenses borne in the past with respect to Investor Shares as to which no 
distribution fee was paid on account of such limitation.  The Distributor may 
pay all or a portion of the distribution fees it receives from the Trust to 
participating and introducing brokers.  The Barr Rosenberg Market Neutral 
Fund paid the Distributor $______ in distribution fees pursuant to the Plan 
for the fiscal year ended March 31, 1998.

     The Plan may be terminated with respect to Investor Shares of any Fund 
to which the Plan relates by vote of a majority of the Trustees of the Trust 
who are not interested persons of the Trust (as defined in the 1940 Act) and 
who have no direct or indirect financial interest in the operation of the 
Plan or the Distributor's Contract (the "Independent Trustees"), or by vote 
of a majority of the outstanding voting securities of that class.  Any change 
in the Plan that would materially increase the cost to the Investors Shares 
of any Fund to which the Plan relates requires approval by the Investor 
shareholders of that Fund.  The Trustees of the Trust review quarterly a 
written report of such costs and the purposes for which such costs have been 
incurred.  Except as described above, the Plan may be amended by vote of the 
Trustees of the Trust, including a majority of the Independent Trustees, cast 
in person at a meeting called for the purpose.  For so long as the Plan is in 
effect, selection and nomination of those Trustees of the Trust who are not 
interested persons of the Trust shall be committed to the discretion of such 
disinterested persons.
    


                                      -11-

<PAGE>

   
     The Distributor's Contract may be terminated with respect to any Fund or 
Investor shares thereof at any time by not more than 60 days' nor less than 
30 days' written notice without payment of any penalty either by the 
Distributor or by such Fund or class and will terminate automatically, 
without the payment of any penalty, in the event of its assignment.

     The Distributor's Contract and the Plan will continue in effect with 
respect to each class of shares to which they relate for successive one-year 
periods, provided that each such continuance is specifically approved (i) by 
the vote of a majority of the Independent Trustees and (ii) by the vote of a 
majority of the entire Board of Trustees (or by vote of a majority of the 
outstanding shares of a class, in the case of the Distributor's Contract) 
cast in person at a meeting called for that purpose.

     If the Distributor's Contract or the Plan are terminated (or not 
renewed) with respect to one or more classes, they may continue in effect 
with respect to any class of any Fund as to which they have not been 
terminated (or have been renewed).

     The Trustees of the Trust believe that the Plan will provide benefits to 
the Trust.  The Trustees believe that the Plan will result in greater sales 
and/or fewer redemptions of Investor Shares, although it is impossible to 
know for certain the level of sales and redemptions of Investor Shares that 
would occur in the absence of the Plan or under alternative distribution 
schemes.  The Trustees believe that the effect on sales and/or redemptions 
benefit the Trust by reducing Fund expense ratios and/or by affording greater 
flexibility to Fund managers.

     CUSTODIAL ARRANGEMENTS.  Custodial Trust Company ("CTC"), Princeton, NJ 
08540, is the Trust's custodian.  As such, CTC holds in safekeeping 
certificated securities and cash belonging to the Trust and, in such 
capacity, is the registered owner of securities in book-entry form belonging 
to a Fund.  Upon instruction, CTC receives and delivers cash and securities 
of a Fund in connection with Fund transactions and collects all dividends and 
other distributions made with respect to Fund portfolio securities.

     INDEPENDENT ACCOUNTANTS.  The Trust's independent accountants are Price 
Waterhouse LLP, 160 Federal Street, Boston, Massachusetts 02110.  Price 
Waterhouse LLP conducts an annual audit of the Trust's financial statements, 
assists in the preparation of the Trust's federal and state income tax 
returns and the Trust's filings with the Securities and Exchange Commission, 
and consults with the Trust as to matters of accounting and federal and state 
income taxation.

                               PORTFOLIO TRANSACTIONS

     INVESTMENT DECISIONS.  The purchase and sale of portfolio securities for 
the Funds and for the other investment advisory clients of the Manager are 
made by the Manager with a view to achieving each client's investment 
objective.  For example, a particular security may be purchased or sold on 
behalf of certain clients of the Manager even though it could also have been 
purchased or sold for other clients at the same time.  Likewise, a particular 
security may be purchased on behalf of one or more clients when the Manager 
is selling the same security on behalf of one or more other clients.  In some 
instances, therefore, the Manager, acting for one client may sell indirectly 
a particular security to another client.  It also happens that two or more 
clients may simultaneously buy or sell the same security, in which event 
purchases or sales are effected prorata on the basis of cash available or 
other equitable basis so as to avoid any one account's being preferred over 
any other account.

     BROKERAGE AND RESEARCH SERVICES.  Transactions on stock exchanges and 
other agency transactions involve the payment of negotiated brokerage 
commissions. Such commissions vary among different brokers.  There is 
generally no stated commission in the case of securities traded in the 
over-the-counter markets, but the price paid for such securities usually 
includes an undisclosed dealer commission or mark up.  In placing orders for 
the portfolio transactions of a Fund, the Manager will seek the best price 
and execution available, except to the extent it may be
    

                                      -12-

<PAGE>

   
permitted to pay higher brokerage commissions for brokerage and research 
services as described below.  The determination of what may constitute best 
price and execution by a broker-dealer in effecting a securities transaction 
involves a number of considerations, including, without limitation, the 
overall net economic result to the Fund (involving price paid or received and 
any commissions and other costs paid), the efficiency with which the 
transaction is effected, the ability to effect the transaction at all where a 
large block is involved, availability of the broker to stand ready to execute 
possibly difficult transactions in the future and the financial strength and 
stability of the broker.  Because of such factors, a broker-dealer effecting 
a transaction may be paid a commission higher than that charged by another 
broker-dealer.  Most of the foregoing are judgmental considerations.

     Over-the-counter transactions often involve dealers acting for their own 
account.  It is the Manager's policy to place over-the-counter market orders 
for a Fund with primary market makers unless better prices or executions are 
available elsewhere.

     Although the Manager does not consider the receipt of research services 
as a factor in selecting brokers to effect portfolio transactions for a Fund, 
the Manager will receive such services from brokers who are expected to 
handle a substantial amount of a Fund's portfolio transactions.  Research 
services may include a wide variety of analyses, reviews and reports on such 
matters as economic and political developments, industries, companies, 
securities and portfolio strategy.  The Manager uses such research in 
servicing other clients as well as the Trust.

     As permitted by Section 28(e) of the Securities Exchange Act of 1934, as 
amended, and subject to such policies as the Trustees of the Trust may 
determine, the Manager may pay an unaffiliated broker or dealer that provides 
"brokerage and research services" (as defined in the Act) to the Manager an 
amount of commission for effecting a portfolio investment transaction in 
excess of the amount of commission another broker or dealer would have 
charged for effecting that transaction.

     The Barr Rosenberg Market Neutral Fund paid brokerage commissions of 
$______ for the fiscal year ended March 31, 1998.

                             TOTAL RETURN CALCULATIONS

     Each Fund computes its average annual total return separately for its share
classes by determining the average annual compounded rates of return during
specified periods that would equate the initial amount invested in a particular
share class to the ending redeemable value of such investment in the class,
according to the following formula:

                                         n
                                   P(1 + T) = ERV

Where:
     T    =    Average annual total return
     ERV  =    Ending redeemable value of a hypothetical $1,000 payment made at
               the beginning of a period at the end of such period
     P    =    A hypothetical initial payment of $1,000
     n    =    Number of years

     Each Fund computes its cumulative total return separately for its share 
classes by determining the cumulative rates of return during specified 
periods that would equate the initial amount invested in a particular share 
class to the ending redeemable value of such investment in such class, 
according to the following formula:
    

                                      -13-

<PAGE>

   
Where:                   T = ERV-1,000
                             1,000

Where:
     T    =    Cumulative rate of return
     ERV  =    Ending redeemable value of a hypothetical $1,000 investment made
               at the beginning of a period at the end of such period.

     The calculations of average annual total return and cumulative total 
return assume that any dividends and distributions are reinvested 
immediately, rather than paid to the investor in cash.  The ending redeemable 
value (variable "ERV" in each formula) is determined by assuming complete 
redemption of the hypothetical investment and the deduction of all 
nonrecurring charges at the end of the period covered by the computations.

     Unlike bank deposits or other investments that pay a fixed yield or 
return for a stated period of time, the return for each Fund will fluctuate 
from time to time and does not provide a basis for determining future 
returns.  Average annual total return is based on many factors, including 
market conditions, the composition of a Fund's portfolio and a Fund's 
operating expenses.

     Average annual total return is calculated separately for Investor Shares 
and Institutional Shares.  Investor Shares and Institutional Shares are 
subject to different fees and expenses and may have different performance for 
the same period.

     The cumulative return of the Barr Rosenberg Market Neutral Fund for the 
period ended March 31, 1998 is as follows:

     PERFORMANCE COMPARISONS.  Investors may judge the performance of the 
Funds by comparing them to the performance of other mutual fund portfolios 
with comparable investment objectives and policies through various mutual 
fund or market indices such as those prepared by Dow Jones & Co., Inc. and 
Standard & Poor's Corporation and to data prepared by Lipper Analytical 
Services, Inc., a widely recognized independent service which monitors the 
performance of mutual funds.  Comparisons may also be made to indices or data 
published in MONEY MAGAZINE, FORBES, BARRON'S, THE WALL STREET JOURNAL, 
MORNINGSTAR, INC., IBBOTSON ASSOCIATES, CDA/WIESENBERGER, THE NEW YORK TIMES, 
BUSINESS WEEK, U.S.A. TODAY, INSTITUTIONAL INVESTOR and other periodicals.  
In addition to performance information, general information about the Funds 
that appears in a publication such as those mentioned above may be included 
in advertisements, sales literature and reports to shareholders.  The Funds 
may also include in advertisements and reports to shareholders information 
discussing the performance of the Manager in comparison to other investment 
advisers and to other institutions.

     From time to time, the Trust may include the following types of 
information in advertisements, supplemental sales literature and reports to 
shareholders: (1) discussions of general economic or financial principles 
(such as the effects of inflation, the power of compounding and the benefits 
of dollar cost averaging); (2) discussions of general economic trends; (3) 
presentations of statistical data to supplement such discussions; (4) 
descriptions of past or anticipated portfolio holdings for the Funds; (5) 
descriptions of investment strategies for the Funds; (6) descriptions or 
comparisons of various investment products, which may or may not include the 
Funds; (7) comparisons of investment products (including the Funds) with 
relevant market or industry indices or other appropriate benchmarks; (8) 
discussions of fund rankings or ratings by recognized rating organizations; 
and (9) testimonials describing the experience of persons that have invested 
in a Fund.  The Trust may also include calculations, such as hypothetical

                  DESCRIPTION OF THE TRUST AND OWNERSHIP OF SHARES

     As more fully described in the Prospectus, the Trust is a diversified 
open-end series investment company organized as a Massachusetts business 
trust. A copy of the Agreement and Declaration of Trust of the Trust, as 
amended (the "Declaration of Trust"), is on file with the Secretary of The 
Commonwealth of Massachusetts.  The fiscal year of the Trust ends on March 
31.  The Trust changed its name to "Barr Rosenberg Series Trust" from 
"Rosenberg Series Trust" on August 5, 1996.

     Interests in the Trust's portfolios are currently represented by shares 
of five series, the Barr Rosenberg Market Neutral Fund, Barr Rosenberg Double 
Alpha Market Fund, U.S. Small Capitalization Series, International Small 
Capitalization Series and Japan Series, issued pursuant to the Declaration of 
Trust.  The rights of shareholders and powers of the Trustees of the Trust 
with respect to such shares are described in the Prospectus.

     As described in the Prospectus, each Fund is further divided into two 
classes of shares designated as Institutional Shares and Investor Shares.  
Each class of shares of each Fund represents interests in the assets of the 
Fund and has identical dividend, liquidation and other rights and the same 
terms and conditions except that expenses, if any, related to the 
distribution and shareholder servicing of a particular class are borne solely 
by such class and each class may, at the discretion of the Trustees of the 
Trust, also pay a different share of other expenses, not including advisory 
or custodial fees or other expenses related to the management of the Trust's 
assets, if these expenses are actually incurred in a different amount by that 
class, or if the class receives services of a different kind or to a 
different degree than the other classes.  All other expenses are allocated to 
each class on the basis of the net asset value of that class in relation to 
the net asset value of the particular Fund.

     The Declaration of Trust provides for the perpetual existence of the 
Trust. The Trust may, however, be terminated at any time by vote of at least 
two-thirds of the outstanding shares of the Trust.

     VOTING RIGHTS.  Shareholders are entitled to one vote for each full 
share held (with fractional votes for fractional shares held) and will vote 
(to the extent provided herein) in the election of Trustees and the 
termination of the Trust and on other matters submitted to the vote of 
shareholders.  Shareholders will vote by individual Fund on all matters 
except (i) when required by the 1940 Act, shares shall be voted in the 
aggregate and not by individual Fund, and (ii) when the Trustees have 
determined that the matter affects only the interests of one or more Funds, 
then only shareholders of such Funds shall be entitled to vote thereon.  
Shareholders of one Fund shall not be entitled to vote on matters exclusively 
affecting another Fund, such matters including, without limitation, the 
adoption of or change in any fundamental policies or restrictions of the 
other Fund and the approval of the investment advisory contracts of the other 
Fund.

     Each class of shares of each Fund has identical voting rights except 
that each class has exclusive voting rights on any matter submitted to 
shareholders that relates solely to that class, and has separate voting 
rights on any matter submitted to shareholders in which the interests of one 
class differ from the interests of any other class.  Each class of shares has 
exclusive voting rights with respect to matters pertaining to any 
distribution or servicing plan applicable to that class.  All classes of 
shares of a Fund will vote together, except with respect to any distribution 
or servicing plan applicable to a class or when a class vote is required as 
specified above or otherwise by the 1940 Act.

     There will normally be no meetings of shareholders for the purpose of 
electing Trustees, except that in accordance with the 1940 Act (i) the Trust 
will hold a shareholders' meeting for the election of Trustees at such time 
as less than a majority of the Trustees holding office have been elected by 
shareholders, and (ii) if, as a result of a vacancy in the Board of Trustees, 
less than two-thirds of the Trustees holding office have been elected by the
    


                                      -15-

<PAGE>

   
shareholders, that vacancy may only be filled by a vote of the shareholders.  
In addition, Trustees may be removed from office by a written consent signed 
by the holders of two-thirds of the outstanding shares and filed with the 
Trust's custodian or by a vote of the holders of two-thirds of the 
outstanding shares at a meeting duly called for the purpose, which meeting 
shall be held upon the written request of the holders of not less than 10% of 
the outstanding shares. Upon written request by the holders of at least 1% of 
the outstanding shares stating that such shareholders wish to communicate 
with the other shareholders for the purpose of obtaining the signatures 
necessary to demand a meeting to consider removal of a Trustee, the Trust has 
undertaken to provide a list of shareholders or to disseminate appropriate 
materials (at the expense of the requesting shareholders).  Except as set 
forth above, the Trustees shall continue to hold office and may appoint 
successor Trustees.  Voting rights are not cumulative.

     No amendment may be made to the Declaration of Trust without the 
affirmative vote of a majority of the outstanding shares of the Trust except 
(i) to change the Trust's name or to cure technical problems in the 
Declaration of Trust and (ii) to establish, designate or modify new and 
existing series, sub-series or classes of shares of any series of Trust 
shares or other provisions relating to Trust shares in response to applicable 
laws or regulations.

     SHAREHOLDER AND TRUSTEE LIABILITY.  Under Massachusetts law, 
shareholders could, under certain circumstances, be held personally liable 
for the obligations of the Trust.  However, the Declaration of Trust 
disclaims shareholder liability for acts or obligations of the Trust and 
requires that notice of such disclaimer be given in each agreement, 
obligation, or instrument entered into or executed by the Trust or the 
Trustees.  The Declaration of Trust provides for indemnification out of all 
the property of the relevant Fund for all loss and expense of any shareholder 
of that Fund held personally liable for the obligations of the Trust.  Thus, 
the risk of a shareholder incurring financial loss on account of shareholder 
liability is considered remote since it is limited to circumstances in which 
the disclaimer is inoperative and the Fund of which he is or was a 
shareholder would be unable to meet its obligations.

     The Declaration of Trust further provides that the Trustees will not be 
liable for errors of judgment or mistakes of fact or law.  However, nothing 
in the Declaration of Trust protects a Trustee against any liability to which 
the Trustee would otherwise be subject by reason of willful misfeasance, bad 
faith, gross negligence, or reckless disregard of the duties involved in the 
conduct of his office.  The Declaration of Trust also provides for 
indemnification by the Trust of the Trustees and the officers of the Trust 
against liabilities and expenses reasonably incurred in connection with 
litigation in which they may be involved because of their offices with the 
Trust, except if it is determined in the manner specified in the Declaration 
of Trust that such Trustees are liable to the Trust or its shareholders by 
reason of willful misfeasance, bad faith, gross negligence or reckless 
disregard of his or her duties.  In addition, the Manager has agreed to 
indemnify each Trustee who is not "an interested person" of the Trust to the 
maximum extent permitted by the 1940 Act against any liabilities arising by 
reason of such Trustee's status as a Trustee of the Trust.

     The officers and trustees of the Trust, as a group, own less than 1% of 
any class of outstanding shares of the Trust.

                          DETERMINATION OF NET ASSET VALUE

     As indicated in the Prospectus, the net asset value of each Fund share 
is determined on each day on which the New York Stock Exchange is open for 
trading. The Trust expects that the days, other than weekend days, that the 
New York Stock Exchange will not be open are Christmas Day, New Year's Day, 
Martin Luther King's Day, President's Day, Good Friday and Memorial Day, 
Independence Day (observed), Labor Day and Thanksgiving Day.

     Portfolio securities listed on a securities exchange for which market 
quotations are available are valued at the last quoted sale price on each 
business day, or, if there is no such reported sale, at the most recent 
quoted bid price.  Price information on listed securities is generally taken 
from the closing price on the exchange where the security is primarily 
traded.  Unlisted securities for which market quotations are readily 
available are valued at the most recent quoted bid price, except that debt 
obligations with sixty days or less remaining until maturity may be valued at 
their amortized cost. Exchange-traded options, futures and options on futures 
are valued at the settlement price as determined by the appropriate clearing 
corporation.  Other assets and securities for which no quotations are readily 
available are valued at fair value as determined in good faith by the 
Trustees of the Trust or by persons acting at their direction.

                         PURCHASE AND REDEMPTION OF SHARES

     The procedures for purchasing shares of each of the Funds and for 
determining the offering price of such shares are described in the 
Prospectus. The Trust has elected to be governed by Rule 18f-1 under the 1940 
Act pursuant to which the Trust is obligated to redeem shares solely in cash 
for any shareholder during any 90-day period up to the lesser of (i) $250,000 
or (ii) 1% of the total net asset value of the Trust at the beginning of such 
period.  The procedures for redeeming shares of each of the Funds are 
described in the Prospectus.

                                      EXAMPLE
                                          
Assumptions:   $100 million invested in portfolio 
               Long component outperforms Short component by 10%(6)

/ /  Market up 15%
     -    Fund's Long component up by 20%
     -    Fund's Short component up only 10%

     Long component plus gains               =    $   120 million
     Short component's increased liability   =    $ - 110 million
                                                  $    10 million increase 
                                                       in net portfolio value
                                                       (plus interest on cash)

/ /   Market down 15%
     -    Fund's Long component down only 10%
     -    Fund's Short component down 20%

     Long component minus losses             =    $    90 million
     Short component's decreased liability   =    $-   80 million
                                                  $    10 million increase 
                                                       in net portfolio value
                                                       (plus interest on cash)

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

     (6)  This example shows the results if the Long component outperforms 
the Short component by 10%.  However, if the Short component outperformed the 
Long component by 10%, the portfolio in this example would lose $10 million 
in value (less the interest on cash).

for the Rosenberg Market Neutral Strategy Portfolio is assumed to be 7% (See 
page A-22 for historical results.)  Actual results may differ.  Other Market 
Neutral strategies may have different levels of expected Standard Deviation.

                               COMPONENTS OF RISK NOTES


Risk, as measured by the Variance of returns, can be broken up into several 
components.  The components of Risk displayed in this chart are:

RESIDUAL SPECIFIC RISK: Risk arising from attributes that are unique to a 
specific company (E.G., company management.)

RESIDUAL COMMON FACTOR: Risk common to a group of stocks, but not to the 
overall market (E.G., industry Risk.)

SYSTEMATIC RISK: Risk common to all stocks (E.G., changes in the general 
economy.)

The Risk for an individual stock is comprised of Residual Specific Risk, 
Residual Common Factor Risk and Systematic Risk.  By combining individual 
stocks into a diversified portfolio, total Risk can be greatly reduced by 
largely eliminating Residual Specific Risk and Residual Common Factor Risks.  
Thus, the Risk in a diversified portfolio comes primarily from Systematic 
Risk.  In a Market Neutral portfolio like Rosenberg's, total Risk can be 
reduced even further by forming Long and Short portfolios with offsetting 
levels of Systematic Risk.  With offsetting levels of Systematic Risk, the 
combined Long-Short portfolio should contain almost no Systematic Risk.  The 
Risk left in a Market Neutral portfolio like Rosenberg's will be comprised of 
Residual Common Factor Risk (the net exposure to these common factors will 
not always be exactly zero) and a small amount of Residual Specific Risk.

                     RISK OF MIS-MATCHING LONG/SHORT COMPONENTS
                                          
/ /  It is unlikely that there will ever be a perfect Hedge.  Unlike matter and
     anti-matter, there is not Stock A and anti-Stock A.

/ /  There is a technique known as pair-wise Hedging, generally implemented
     along industry lines: E.G., General Motors is bought and Chrysler is sold
     Short.  However, it is rare for two paired stocks to effectively Hedge all
     factors of Risk.  Most stocks have exposures to a number of different Risk
     characteristics.

/ /  A manager will intentionally accept a certain amount of Risk in order to
     exploit the opportunities that arise from the identification of overvalued
     and undervalued stocks.

/ /   The key is, at the portfolio level, to be aware of the active Risk and
     balance it against the opportunities for superior performance.

                     INDUSTRY DIVERSIFICATION: SHORTS VS. LONGS
                 ROSENBERG MARKET NEUTRAL STRATEGY PORTFOLIO NOTES

     One of the targets for Rosenberg's market neutral portfolios is to have 
offsetting industry exposures in the Long and Short portfolio components.  
The chart shows the industry positions of the Long and Short components of 
Barr Rosenberg Market Neutral Strategy Portfolio as of December 31, 1997.  
The composite portfolio's Long Position in each industry is shown in the bars 
extending to the right and the Short position in the bars extending to the 
left. The net industry exposure of the portfolio (the Long Position less the 
Short position) is shown by the yellow dot.  For example, in Iron and Steel 
stocks, the portfolio has a 1.3% Short and a 2.3% Long Position, for a net 
exposure to the Iron and Steel industry of +1.0%.  The net exposure to an 
industry is expected to be on average, over time, close to zero, but at any 
given point the net exposure typically can range from (plus or minus) 5%.  
This non-zero net industry exposure is the result of the Manager making 
decisions about the trade-off between the potential return from an individual 
stock and the Risk of creating a portfolio net exposure to an industry.

     Example of offsetting industry exposures: part of the Long Position in 
trucking, freight is offset by the Short position in railroads, transit.

ACTIVE EXPOSURE TO RISK INDEXES NOTES

Risk Indexes, also called common factors of Risk, are Risks that are common 
to a group of stocks, but not the overall market.  This chart uses 12 of the 
widely used BARRA Risk factors (see below for definitions).  Since the 
components of the Risk factors are measured in different units, one must use 
a standardized measure to allow the components to be aggregated into a single 
Risk factor measure.  This standardized measure is the Standard Deviation of 
the individual components measured relative to a universe of large 
capitalization stocks.  The active exposures shown in this chart represent 
the number of Standard Deviation units by which the Rosenberg Market Neutral 
Strategy's exposures to Risk factors differs from zero.  For a given Risk 
factor, if the bar is to the right (left), Rosenberg has an exposure greater 
(less) than zero.  The chart displays the active exposure to Risk factors as 
of December 31, 1997 for Rosenberg Market Neutral Strategy.

Definitions of Risk Indexes (13): (See page A-93 for descriptors used in Risk 
Indexes)

VARIABILITY IN MARKETS: The Risk of a company as perceived by the market.  If 
the market was completely efficient, then all information on the state of the 
company would be reflected in the stock price.  In this measure historical 
prices and other market variables are used in an attempt to reconstruct the 
state of the company.  The descriptors include historical measures of Beta 
and residual Risk and various liquidity measures.

SUCCESS: How successful has the company been, and how does the market value 
the company? If investors are optimistic about future prospects and the 
company has been successful in the past, then the implication is that the 
firm is sound and that future Risk is likely to be lower.  The descriptors of 
success include: relative strength, historical Alpha, recent earnings change, 
IBES earnings increase, dividend cuts (five years), growth in earnings per 
share.

SIZE: A size index based on assets and capitalization.  The descriptors of 
size include: capitalization, total assets and indicators of earnings history.

TRADING ACTIVITY: Indicators of share turnover.  The descriptors include: 
share turnover for several time periods, common stock price, number of IBES 
analysts covering the company and trading volume/Variance.

GROWTH: To the extent that a company attempts to provide returns to 
stockholders by an aggressive growth strategy requiring the initiation of new 
projects with uncertain cash flows (rather than the more stable cash flows 
from existing operations) the company is likely to be more Risky.  The 
descriptors of growth include: growth in assets, payout and dividend policy, 
earnings-to-price ratio and earnings and capital structure change.

EARNINGS/PRICE: The current, trailing five-year, and IBES analysts forecasted 
earnings-to-price ratio.

BOOK/PRICE: The current book-to-price ratio.

EARNINGS VARIATION: A measure of the unpredictable variation in earnings over 
time.  The descriptors include: Variance of earnings and cash flows, Standard 
Deviation of IBES earnings forecasts divided by price and extraordinary items.

FINANCIAL LEVERAGE: The more highly leveraged the financial structure, the 
greater the Risk to common shareholders.  The descriptors include: 
debt-to-asset ratio, book value of leverage, interest rate sensitivity.

FOREIGN INCOME: A measure of the dependency of a company to exports as 
indicated by the level of foreign operating income.

LABOR INTENSITY: A measure of the mix of capital and labor used by a company. 
The descriptors include: net plant and equipment, inflation adjusted plant 
and equipment and labor share.

YIELD: A prediction of a company's common stock dividend Yield.

(14) The two measures of the Risk of Rosenberg's Market Neutral Strategy used 
in this exhibit are the Standard Deviation of the monthly total returns of 
the Rosenberg Market Neutral Strategy and the range of total return measured 
over moving 12-month periods.  First, the annual Standard Deviation of the 
monthly total return of Rosenberg's Market Neutral Strategy is shown for the 
period from the inception of the Strategy in March 1989 through December 1997 
and for the three- and five-year periods ending December 1997.  In addition, 
the lowest and highest total returns of the Rosenberg Market Neutral Strategy 
in any moving 12-month period from the inception of the Strategy in March 
1989 through December 1997 is shown along with the T-bill return for the 
corresponding periods.

PROBLEMS

/ /  No supply for a particular stock

/ /  Short Execution hindered by chaotic market

/ /  Short Squeeze

SOLUTIONS

/ /  Have many stock positions and no large single positions.  Restrict Shorts
     to those stocks where the Prime Broker is confident that they are
     available.

/ /  Have a well-diversified Short portfolio already in place.  Use an
     Optimization process which permits flexibility in substituting stocks for
     the Short portfolio, depending on what is available.  Be able to respond
     real time.

/ /  Monitor supply of stock available and outstanding Short sales.

                             ROSENBERG EXPERIENCE (15)




/ /  Stocks with ample supply: average list of Short candidates from Rosenberg's
     Prime Broker is over 4,000 stocks (16)

/ /  Rosenberg's largest Short position: about 1.1% of Short portfolio
     (17)

/ /  Rosenberg's typical Short position: 1/4 of 1% of Short portfolio
     (18)

/ /  In almost 9 years of Rosenberg managing market neutral portfolios, the
     largest percentage appreciation of any Short position was 406% relative to
     the market.  This position represented less than 0.18% of the portfolio's
     net asset value.  The negative impact to total return was less than 0.75%.

                          RISK OF MIS-MEASUREMENT OF BETA

/ /  Beta is an estimate or measure of Systematic Risk or market-related Risk.

/ /  Systematic Risk for an individual stock is usually about 30% of the stock's
     total Risk.  Beta only measures this 30% of the Risk.

/ /  70% of the Risk of an individual stock is Residual Specific Risk and
     Residual Common Factor Risk, which can be diversified away.  To the extent
     that Risk is diversified away, Beta will typically measure over 90% of the
     Risk of a portfolio.

/ /  Because the measurement of Beta is only an estimate, there will be
     differences in the quality - and hence the accuracy - of estimates of Beta.

TYPICAL METHOD:

     / /  Regression based on most recent 60 months of returns.

ROSENBERG METHOD:

     / /  Based on the company's current composition across various industries.

     / /  Use 13 Risk measures (E.G., book/price, financial leverage, foreign
          income) and 38 industries to calculate each factor's contribution to
          the stock's expected Beta.

     Beta is a measure of the changes in an asset's return in relation to 
changes in the return of a broad portfolio of assets or the "market."  In 
this exhibit, the Beta of Rosenberg's Market Neutral Strategy is measured 
relative to the S&P 500 Index.  The historical Beta of the Rosenberg Market 
Neutral Strategy from its inception in March 1989 through December 1997 was 
measured.  In addition, the Beta of the Rosenberg Market Neutral Strategy 
over rolling 24-month periods was measured.  In both cases, the measured Beta 
was not statistically different from zero, indicating that the Rosenberg 
Market Neutral Strategy has historically had almost no exposure to the equity 
market (as measured by the S&P 500.)  For a strategy to have a Beta of zero 
indicates that the return of the market, either positive or negative, has no 
impact on the returns of that strategy.

PROBLEMS

/ /  Failure to distinguish between overvalued and undervalued stocks.

/ /  Worse still, what if the Longs don't appreciate as much as the Shorts? Or
     the longs decrease in value more than the shorts?

/ /  Does the size of Short portfolios under management justify a comparable
     effort to the Long portfolios under management given the relative assets of
     each? Are Shorts a natural by-product of manager's analysis? (See footnote
     48)

SOLUTION

/ /  Analysis of manager's investment process and logic as well as empirical
     evidence to validate it.

     The batting average methodology is designed to evaluate the predictive 
power of the Rosenberg models.  The idea is to determine whether securities 
that Rosenberg predicted would outperform actually outperformed over the 
subsequent 12 months and whether securities that Rosenberg predicted would 
underperform actually underperformed over the subsequent 12 months.  A 
correct classification in each of these cases is considered a hit.  For each 
month since April 1, 1993, Rosenberg computed the percent of predictions that 
were hits.  The average of this percentage for the period April 1, 1993 
through December 31, 1997 is then computed and presented in the batting 
average exhibit.

     In order to do this analysis, Rosenberg divided securities into 5 
capitalization groups.  The following analysis was performed for each 
capitalization group.  Rosenberg ranked securities according to the output of 
the models from those Rosenberg expected to perform the best to those 
Rosenberg expected to perform the worst.  Then, the securities in the top 
half of this ranked list were compared to the ranked list of subsequent 
returns for each security.  If a security fell in the top half of both the 
predicted list and subsequent return list, then it was a hit.  If a security 
fell in the bottom half of each list, then it was also a hit.  Rosenberg 
included in the analysis all securities for which there was data as of the 
beginning of the month to produce results that were free of Survivorship Bias.

(22)   The exhibit reports the average monthly performance of Rosenberg's 
Market Neutral Strategy.  Months where the return on the S&P 500 Index was 
greater than zero are up markets and months where the return on the S&P 500 
Index was less than zero are down markets.  The period covers March 1989 to 
December 31, 1997.  Out of the 106 months in this time period there were 74 
"up" months and 32 "down" months.

                  POTENTIAL BENEFITS OF ROSENBERG MARKET NEUTRAL

- -    Returns do not depend on the systematic returns of the underlying asset
     class
     -    Potential to provide positive excess return even during down markets

- -    More flexibility for plan sponsor/client
     -    Pay only for active decisions not diversification or general market
          appreciation

                                   FOUR CONCEPTS
                                          
1.   Short Sale: Borrow a stock with the agreement to return it in the 
future, thereby creating a liability.  Sell the borrowed stock now, expecting 
to buy it back to return to the lender at a lower price in the future.  The 
liability is the cost of buying the stock to return it to the lender.  Thus 
the amount of the liability fluctuates with the price of the stock.

2.   Beta: A measure of the volatility of a stock or portfolio relative to 
the movements in the overall market as measured by some index (E.G., S&P 500).

3.   Alpha: The excess return earned on a stock or portfolio above the return 
one would have expected given the level of Risk of the stock or portfolio.  
It is a measure of how much value, if any, a portfolio manager has added due 
to his skill.

4.   Risk: A common measure of Risk is Variance.  The larger the range of 
possible outcomes, the larger will be the value of the Variance.  An 
investment with a zero Variance will have no Risk - there is only one 
possible outcome. The Standard Deviation is the square root of the Variance.  
It is a useful measure because 2/3 of the outcomes should fall within 
plus/minus one Standard Deviation.  95% of the outcomes should fall within 
plus/minus two Standard Deviations.

(31) This example shows the results if the manager has stock selection skill 
so that the Long component outperforms the Short component by 10%. However, 
if the manager did not have skill so that his Short component outperformed 
his Long component by 10%, the portfolio in this example would lose $10 
million in value (less the interest on cash).

     A common measure of Risk is the Standard Deviation of return around an 
average annual return.  This measure is calculated so that two-thirds of the 
outcomes are likely to fall within one Standard Deviation; 95% of the 
outcomes are likely to fall within 2 Standard Deviations; and 99% of the 
outcomes are likely to fall within 3 Standard Deviations.

                    SUBSTITUTING ROSENBERG MARKET NEUTRAL STRATEGY
                    IN A U.S. CORE PORTFOLIO CAN REDUCE RISK NOTES
                                           

Standard Deviation of combined portfolio: The annualized Standard Deviations 
of the portfolio combining U.S. Large Stocks (as represented by the S&P 500) 
with various percentages of Rosenberg's Market Neutral Strategy or 
Intermediate-Term Government Bonds (see data series descriptions on page 
A-10.)  The Variance of the portfolio is given by the formula:

(WEIGHT 2  large stocks * VARIANCElarge stocks)  +
     
(WEIGHT 2 Rosenberg or intermediate bonds  *  VARIANCE Rosenberg or 
intermediate bonds)  +

(2 *  WEIGHTlarge stocks  *  WEIGHT Rosenberg or intermediate bonds  * 
COVARIANCE large stocks and Rosenberg or intermediate bonds)

The Standard Deviation of the portfolio is the square root of this Variance. 
The Standard Deviation of a portfolio can decrease as assets that have 
negative Correlation with the initial asset class are added to the portfolio. 
 This chart demonstrates that portfolio Risk has been reduced faster by 
adding Rosenberg's Market Neutral Strategy to a U.S. Large Stock portfolio 
than by adding Intermediate-Term Government Bonds.  However past performance 
is no guarantee of future performance.

Legend for chart: 

U.S. Large Stocks represented by the S&P 500 Index.

Notes on chart:

Period under study: March 1989 through December 1997.
For example, the annual Standard Deviation of a portfolio invested 50% in 
large stocks and 50% in intermediate-term government bonds is about 7.5%.

For example, the annual Standard Deviation of a portfolio invested 50% in 
large stocks and 50% in Rosenberg's Market Neutral Strategy is about 6.4%.

     IBES (Institutional Broker Estimate Service) is an organization that 
collects and publishes corporate earnings forecasts from institutional 
analysts.

     Earnings Change/Initial Price, also called earnings Yield, measures the 
one year change in earnings for a company divided by the price of the 
company's stock at the start of the period.  It is a measure which compares 
the growth in earnings across companies.  This chart divides all U.S. 
companies into five groups (quintiles) based on earnings change divided by 
initial price as forecast by IBES analysts.  The bottom quintile contains the 
companies with the lowest IBES forecast earnings change/initial price, the 
fourth quintile contains the companies with the next lowest IBES forecast 
earnings change/initial price, and so on.  The chart compares the IBES 
forecast earnings change/initial price with actual reported earnings.  The 
chart covers the period from 1976 to September 1996.

                        EXAMPLE OF A QUARTERLY SURPRISE NOTES


IBES (Institutional Broker Estimate Service) is an organization that collects 
and publishes corporate earnings forecasts from institutional analysts.

The vertical axis measures the average absolute percentage earnings surprise 
as given by the formula in the footnote to the chart.  Earnings surprises are 
differences between estimated earnings and actual reported earnings.  The 
absolute value of earnings surprises are used so as to treat positive and 
negative differences between estimated and actual earnings similarly.  The 
average of these absolute earnings surprises is used to limit the effects of 
unusually large earnings surprises.  The earnings surprises are measured 
based on the quarterly earnings forecast immediately prior to the reported 
third quarter 1996 earnings.  The capitalization buckets are groups of 
companies sorted by the capitalization of the company (a measure of the size 
of the company.)  The horizontal axis groups companies into groups of 500 
companies, from the largest U.S. companies on the left to the smallest U.S. 
companies on the right.

Footnote to chart:
To limit the effect of outliers, percentage surprise is defined as: 100 * 
(Actual Earnings - Estimated Earnings)/.5*(absolute value of (Actual Earnings 
- -Estimated Earnings))

                      PERCENT OF COMPANIES COVERED BY IBES NOTES


IBES (Institutional Broker Estimate Service) is an organization that collects 
and publishes corporate earnings forecasts from institutional analysts.  This 
chart reports on IBES analyst coverage as of August 1996.

The vertical axis on the chart measures the percentage of companies for which 
quarterly earnings forecasts were made by 1, 2, or 3 or more IBES analysts.

The percentage coverage by IBES analysts is broken down by the capitalization 
of the company (a measure of the size of the company.)  The horizontal axis 
groups companies into groups of 500 companies, from the largest U.S. 
companies on the left to the smallest U.S. companies on the right.  IBES 
analyst coverage declines steadily as company size, measured by 
capitalization, decreases.  Since smaller companies have fewer analysts 
covering them, there may be more opportunities to identify possible 
overpriced stocks which would be candidates for Short selling.

In this chart, the total return of a representative Market Neutral portfolio 
(one of the 9 accounts that comprise the Rosenberg Market Neutral Strategy 
Portfolio) managed by Rosenberg is "decomposed" into the return achieved by 
the portfolio of Long Positions, the return from the portfolio of Short 
positions and the return from the "Short Stock Rebate."  The Short Stock 
Rebate is the return generated by investing the cash generated by the Short 
positions and is generally equal to the federal funds rate less a small fee, 
charged by the Prime Broker.  The total return of this representative 
portfolio equals the return of the Long portfolio component plus the Short 
Stock Rebate less the return on the Short portfolio component.

In order to analyze the source of Alpha or added value of a Market Neutral 
strategy, there has to be a Benchmark against which to compare the Long 
holdings and the Short holdings.  For Rosenberg's Market Neutral Strategy, 
there is no external Benchmark against which to compare the Longs and Shorts. 
 Rosenberg's Long holdings are not constructed to match an external Benchmark 
but to match the characteristics of the Shorts.  Similarly, Rosenberg's Short 
holdings are not constructed to match an external Benchmark, but to match the 
characteristics of the Longs.  In essence, the Longs and Shorts are each 
other's Benchmark.

In order to have as accurate a Benchmark as possible, a factor model was used 
for the Benchmark that included 11 Risk Index factors and 38 industry 
factors. At the beginning of each month, the average exposure of the Longs 
and Shorts to each of these factors was computed.  For example, if the 
portfolio was 8% Long in an industry and 4% Short, the average Benchmark 
exposure to that industry was 6%.  The factor returns (an estimate of the 
return that could be specifically attributed to a given exposure to that 
factor) were then computed for that month using standard Regression 
techniques.  Finally, the Benchmark exposure to a factor was multiplied by 
the factor return and summed to produce the overall Benchmark return for the 
month.  The return from the Longs and Shorts are then compared to this factor 
Benchmark return to determine the value added from the Longs and Shorts.

          At heart, Rosenberg is a fundamental investor.  Rosenberg believes 
that stock prices imperfectly reflect the present value of the expected 
future earnings of companies, their "fundamental value."  Since market prices 
will converge towards fundamental value over time, Rosenberg believes that 
any investor who can accurately determine fundamental value, and who applies 
a disciplined investment process to select those stocks that are currently 
misvalued, will outperform the market over time.

          The premise of Rosenberg's investment philosophy is that there is a 
link between the price of a stock and the underlying financial 
characteristics of the company.  In other words, the price reflects the 
market's assessment of how well the company is positioned to generate future 
earnings and/or future cash flow.  Rosenberg tries to identify and purchase 
those stocks which are undervalued -- they are cheaper than similar stocks 
with the same financial characteristics.  Also Rosenberg engages in Short 
sales with respect to those stocks which it believes are overvalued -- they 
are more expensive than similar stocks with the same financial 
characteristics.  Rosenberg believes that the market will recognize the 
"better value" and move to correct the mispricing by purchasing or selling 
the stock, as the case may be.

          Rosenberg's determination of the "average" valuation for a stock is 
based upon a comparison of similar companies.  Rosenberg knows that in any 
group of similar companies, there are usually some that are overvalued, some 
that are undervalued, and some that are fairly-valued relative to the average 
valuation for the group.  These valuation errors are usually present in every 
sector of the market and can be identified through rigorous Quantitative 
analysis of fundamental data.

          Rosenberg seeks to add value as an active equity manager through 
stock selection, and usually not by predicting the performance of Risk 
factors, industries, or the overall market.

          Even if investors looked at all the relevant data and processed that
data correctly, there is still the possibility that they might not apply the
conclusions consistently across all stocks.  In order to ensure consistency one
must simultaneously look at all the same factors (hopefully with detailed and
accurate measures) across all similar stocks, and apply consistent valuation
rules.  Yet how likely is it that people can do that? There have been many
studies in different fields that address the issue of inconsistent application. 
The situations studied were as diverse as admissions to graduate school,
loan-granting, prescribing a course of medical treatment, and predicting returns
on stocks.  In almost all the studies, it has been shown that simple models
which duplicate the decision factors that an

expert/judge/forecaster uses produce better forecasts than the original 
experts being modeled.(42)  How can that be? After all, there is some 
information that can't be quantified and some intuition that can't be 
captured in a model.

          It is possible for models to be superior because the lack of some 
details is more than offset by the consistency the models bring.  Often human 
experts apply their judgments inconsistently.  As humans, their moods vary, 
and at times they are preoccupied with an unrelated idea.  Sometimes they do 
not employ exactly the same standards they use in judging a stock today that 
they used yesterday.  In addition, humans tend to ignore subtle distinctions 
in information.  They may not respond at all unless the distinctions are 
obvious, and then they may overreact.  After all they are not machines! And 
that is exactly the point.  The more cases an expert has to consider, the 
more likely it is that inconsistencies in thinking will arise.

Rosenberg utilizes three stock models: An Appraisal Model, an Earnings Change 
Model, and an Investor Sentiment Model.  The insights gained from these three 
models are combined to produce a predicted return for each stock in 
Rosenberg's selection universe.  Rosenberg then uses their Risk Model to form 
portfolios that they believe represent the optimal tradeoff between the 
returns predicted by their stock selection models and the common sources of 
Risks for these stocks.

                             THE APPRAISAL MODEL NOTES


Appraisal Model

          Fundamental valuation of stocks is key to Rosenberg's investment 
process, and the heart of their valuation process lies in the Appraisal 
Model. An important feature of the Appraisal Model is the classification of 
U.S. -based companies into any of 166 groups of "similar" businesses.  
Rosenberg decomposes each company into its individual business segments, and 
compares each segment with similar business operations of other companies.  
Rosenberg appraises the company's assets, operating earnings, and sales 
within each business segment by applying the market's own average appraisal 
of assets, operating earnings and sales for those same business segments.  
Rosenberg then combines the segment appraisals to arrive at total balance 
sheet, income statement, and sales appraisals for the entire company.  
Rosenberg simultaneously adjusts the segment appraisals to include the 
appraisals for factors which are declared only for the total company, such as 
taxes, capital structure, and pension funding.  In total Rosenberg uses over 
190 valuation factors to characterize the income statement, balance sheet, 
and sales elements. The result is a single valuation for each of over 5,000 
companies that Rosenberg follows in the U.S.

          The difference between ROSENBERG'S valuation and the market price 
reflects an opportunity for profit.  Rosenberg develops "appraisal Alphas" - 
the expected rate of extraordinary return - by adjusting for the rate at 
which the market has corrected for such misvaluations in the past.

                                  COMPANY XYZ NOTES

          As an illustration of how the Appraisal Model is used, consider a 
simplified example of a mythical machinery and metal products company, 
Company XYZ. For most companies Rosenberg would have over 190 fundamental 
valuation elements, but for the sake of simplicity this example shows just 
five items.  On their financial statements, Company XYZ reports $10 per share 
of machinery assets and $5.50 per share of metal products assets; $1.30 per 
share of receivables; $8.00 per share of long-term debt; and, from the 
footnotes to the financial statements, $2.00 per share in pension surplus.  
Using the Appraisal Model, Rosenberg determines how much the market currently 
values each of these valuation elements.  For example, the Appraisal Model 
finds that, on average, the market currently values a dollar of machinery 
assets at $1.75.  By multiplying the reported dollars per share of each 
valuation element by the current market appraisal for that element, Rosenberg 
determines the contribution to total company fair value for each fundamental 
valuation element.  Summing up all of these contributions to fair value gives 
Rosenberg the total fair value for Company XYZ. According to Rosenberg's 
Appraisal Model, Company XYZ is currently a bargain, and a candidate for 
purchase, since Rosenberg's estimated fair value is $20.07 and the market 
price is $18.50.  Rosenberg re-estimates the market and total company 
appraisals continuously throughout the trading day.

          Rosenberg's market appraisals of the fundamental valuation elements 
they consider are updated continuously.  The chart shows the changing market 
appraisal for Cash and Short-Term Investments as determined by Rosenberg's 
Appraisal Model.  The appraisal of Cash and Short-Term Investments is 
multiplied by the company's reported Cash and Short-Term Investments to 
determine the adjustment to the overall valuation of the company.  The 
appraisal for Cash and Short-Term Investments is measured relative to zero, 
and thus its continuous valuation above zero indicates that Cash and 
Short-Term Investments is a premium item on the balance sheet and always 
contributes positively to the overall value of a company.

EARNINGS CHANGE MODEL

          Rosenberg's proprietary Earnings Change Model analyzes more than 20 
explanatory variables to predict individual company earnings over a one-year 
horizon.  The variables are fundamental and fall into three categories: 
measures of past profitability, measures of company operations and consensus 
analyst earnings forecasts.  The Earnings Change Model is independent of the 
Appraisal Model and projects the change in a company's earnings in 
cents/current price. The value of the projected earnings change is converted 
to an "earnings change Alpha" by multiplying the projected change by the 
market's historical response to changes of that magnitude.

          Under general assumptions, Rosenberg believes that the price of an 
individual stock is equal to the present value of the future earnings or cash 
flow of the company.  Thus, one measure of the success of a strategy in 
identifying undervalued stocks is the degree to which it can, over time, buy 
more future earnings per dollar of initial investment than the Benchmark 
universe.  This measure of future earnings per dollar of initial investment 
is also called the earnings Yield.  This chart shows the level of reported 
earnings and earnings from continuing operations (reported earnings before 
special and extraordinary items) relative to initial cost after a two year 
holding period (the earnings Yield 2 years after purchase) for the stocks 
invested in by Rosenberg (43) and the market universe of stocks.  After a two 
year holding period, the Rosenberg portfolio provides a higher level of 
future earnings per dollar invested (a higher earnings Yield) than the market 
universe.  The analysis covers the period from the inception of Rosenberg 
Institutional Equity Management in June 1985 through December 1995 (the last 
date for which 2 years of future earnings could be determined as of December 
31, 1997.)

Investor Sentiment Model:     Avoid Bargains that Investors will Shun Notes


Investor Sentiment Model

ROSENBERG'S Investor Sentiment Model quantifies investor sentiment about 
features of stocks which influence price but which are not captured by the 
Appraisal Model or the Earnings Change Model.  Rosenberg incorporates 
investors' perception of the "quality" of individual companies by looking at 
past price patterns (Market Quality) and by calculating the probability that 
future earnings will disappoint investors (Earnings Quality.)  Rosenberg's 
models also capture market enthusiasm towards individual stocks by looking at 
the "bandwagon" effects that generally occur following broker 
recommendations, revisions in analyst estimates, earnings surprises and 
disappointments, and other measures of market sentiment.  In addition to 
improving their overall prediction of individual stock returns, Rosenberg 
uses their Investor Sentiment Model to help them time their trades.

                               PREDICTING RETURNS NOTES


          The output of Rosenberg's three stock selection models is predicted 
returns for each company in their universe of stocks.  The areas covered by 
their three models fall into three general categories of stock selection that 
most managers rely on to some degree: valuing companies; forecasting earnings 
changes; and gauging investor enthusiasm.  Rosenberg's models contribute 
proprietary information in each of these areas.  The market and company 
appraisals determined by Rosenberg's Appraisal Model provide company 
valuations. Rosenberg's Earnings Change Model considers the competitive 
forces affecting company profitability to help improve their company earnings 
forecasts.  In addition, Rosenberg's quantification of quality and opinion 
measures in their Investor Sentiment Model gives them a view of investor 
enthusiasm towards individual companies.

          Each of Rosenberg's three models produces an overall predicted 
relative return, or Alpha, for each company in Rosenberg's stock selection 
universe.  A company's earnings change Alpha and investor sentiment Alpha is 
added to its appraisal Alpha to arrive at a total company Alpha.  It is these 
predicted returns that are used by Rosenberg's Risk Model and Optimization 
process to build a portfolio.

                           Recommended Portfolio Holdings
                                          
                                          
                                          
          In building portfolios, Rosenberg wants to ensure that they place 
their "bets" where they feel most confident in their information.  As stock 
pickers, their information is about individual stocks.  Thus, they want their 
portfolios to "bet" on the individual companies identified by their models 
and typically not on Risk factors, industries, or the direction of the market 
for which they do not have unique insights.

All data is fed into a computer program that uses complex piece-wise linear 
functions to approximate a quadratic function and optimize the portfolio's 
trade-off between Risk and return.  The Optimizer sets "targets" for 
portfolio exposure to systematic factors of Risk after analyzing the Risk 
characteristics of the Benchmark.  For Market Neutral portfolios, the 
Benchmark of the Long portfolio will be the Short portfolio (or, 
equivalently, the Benchmark of the Short portfolio is the Long portfolio.)  
The Optimizer then exploits the information developed by the stock selection 
system to maximize return while eliminating unnecessary Risk.  It recommends 
positions in companies that in the aggregate, constitute the most efficient 
portfolio.  Data on each executed trade are "looped back" into the Optimizer, 
which reassesses the relative portfolio Risk before recommending additional 
trades.  Trades are recommended only when the net benefit exceeds the 
expected transaction cost.  Since the Optimizer operates in real time, 
Rosenberg is prepared to respond immediately to investment opportunities.

               WHY ROSENBERG EXPECTS ITS INVESTMENT APPROACH TO WORK

/ /       Consistent comprehensive processing of relevant data 
          -         all the same factors 
          -         processed at the same time 
          -         across all similar stocks

/ /       Consideration of the broader forces at work in competitive economies

/ /       Attempts to avoid the errors that naturally arise from qualitative
          investment decision processes 
          -         decision short cuts 
          -         overly optimistic forecasts of companies' future earnings

/ /       Attempts to buy future earnings at a discount

/ /       Track record in identifying both overvalued and undervalued stocks
          using a disciplined investment approach.  (Past performance is no
          guarantee of future performance.)

/ /       Barr Rosenberg has over 25 years' experience in analyzing and
          measuring the Risk of equity portfolios.  This is critical in
          controlling Common Factor Risk as well as Systematic Risk in
          constructing Long/Short portfolios.

/ /       A systematic, Quantitative approach which seeks to identify hundreds
          of overvalued and undervalued stocks.  This gives Rosenberg the
          flexibility to control Risk and minimize trading costs in constructing
          a Long/Short portfolio.

                               HISTORICAL HIGHLIGHTS
                                          
/ /       Broad definition of Market Neutral investing is any zero Beta
          investment strategy, I.E., any strategy which is not exposed to the
          Systematic Risk in the particular asset class.

/ /       1949 - Concept was first used by A. W. Jones in an investment
          partnership.

/ /       1967 - The book BEAT THE MARKET by Edward O. Thorpe outlined a Hedged
          approach to stock/warrant trading.

/ /       1973 - The Black/Scholes options-pricing model was published.  This
          model used the idea of a riskless Hedge between a call option and the
          underlying stock.

/ /       1977 - Long Treasuries futures contracts were created which helped
          make Market Neutral investing possible in the fixed income markets.

/ /       1987 - Morgan Stanley's Quantitative group engaged in equity pairs
          trading.  Under the net-capital rules for broker dealers, leverage was
          increased beyond the standard 2:1 ratio that typically applies to
          customers and pension plans.

/ /       1988 - Internal Revenue Service issued a private letter ruling which
          held that Short sales did not result in unrelated business taxable
          income.

/ /       1989 - Rosenberg forms a partnership to implement a Market Neutral
          strategy.

/ /       1995 - IRS issued revenue ruling (IRB 1995-4, #29) which states that
          Long/Short investing does not create UBIT.

/ /       1997 - "Short-Short" rule - Taxpayer Relief Act of 1997 eliminates
          this rule making it feasible for mutual funds to engage in significant
          Short sales and thus to offer Market Neutral products.

/ /       1997 - Today, there are many different types of Market Neutral
          strategies with widely differing risk/return characteristics and uses
          of leverage.

                       ROSENBERG'S HISTORY OF MARKET NEUTRAL
                                          
/ /       In 1978, at BARRA Seminars, Barr Rosenberg suggested that some
          managers could increase rewards for clients by selling stocks held in
          clients' index funds.  This would be a practical way of benefiting
          from the identification of overvalued stocks without Short selling
          them.

/ /       In 1988, as soon as the IRS private letter ruling was released,
          Rosenberg began to actively pursue Market Neutral opportunities, and
          in 1989 Rosenberg became the first Market Neutral client of Bear
          Stearns.

/ /       1997 - Rosenberg launches a Market Neutral equity mutual fund.

          -         Market Neutral delivers double Alpha (from identifying both
                    overvalued and undervalued stocks) plus T-bill returns 
          -         Combined, the return consists of double Alpha from the

          -         Systematic, or general market Risk as evidenced by the Risk
                    of the S&P 500 Index plus manager's stock selection Risk

(45)  This example shows the results if the Long component outperforms the 
Short component by 10%.  However, if the Short component outperformed the 
Long component by 10%, the portfolio in this example would increase by only 
$15 million in the scenario where the market is up 15% and would lose $15 
million in the scenario where the market is down 15%.

                        DIFFERENT MARKET NEUTRAL STRATEGIES:
            THREE TYPES OF INVESTMENT IDEAS GENERATE HEDGED MARKET RISK


/ /       ARBITRAGE BETWEEN LINKED SECURITIES: A IS UNDERVALUED RELATIVE TO B

          -         Buy A and sell Short B; profit from correction of the
                    misvaluation

          -         Example: A, the index bundle of stocks is cheaper than B,
                    the index future

          -         Hedge may be nearly perfect, because the securities are
                    linked

          -         Typically low-reward and low-Risk

/ /       ONE-SIDED IDEAS, WHOSE MARKET RISK IS OFFSET BY DERIVATIVE HEDGES

          -         Reward may be high or low (single Alpha)

          -         The Hedge incurs a cost (a drain on Alpha)

          -         The result: Single Alpha minus Hedging cost

          -         Drawback: there may be no suitable derivative security for
                    the Hedge

/ /       TWO-SIDED RISK-CANCELING IDEAS: A IS UNDERVALUED; B WHICH IS LIKE A IS
          OVERVALUED

          -         Buy A and sell Short B; Profit as the market bids up the
                    price of A and bids down the price of B.

                    -         Reward on each side may be high or low (double
                              Alpha)

                    -         The result: Double Alpha, potentially the most
                              profitable

              SUGGESTED SELECTION CRITERIA FOR MARKET NEUTRAL MANAGERS
                                          
/ /       Risk control capability

/ /       Stock selection skill (47)

          -         understand biases and market environment impact 
          -         adequate stock selection menu

/ /       Ability to Short (48)

          -         Prime Broker 
          -         fee income justification 
          -         natural result of process

/ /       Experience

/ /       Capacity


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

(47)  When evaluating a Market Neutral manager one should determine if the 
manager has stock selection skill.  Two aspects of this skill are especially 
important for implementing a Market Neutral strategy.  First is an 
understanding as to whether the manager's stock selection skill is limited to 
certain types of stocks, E.G. small growth or large value.  One should also 
examine the possibility that the manager's stock selection skill is more or 
less effective in different market environments, E.G. a strong economic 
environment.  Having done that analysis, one should then consider how broadly 
the manager can apply his stock selection skill, E.G. does the skill apply 
across all industries and capitalization sectors.  The reason this is 
important is that, generally speaking, the more narrow the manager's stock 
selection skill, the more difficult it is to create an effective Hedge 
between the Long and Short portfolio components.

(48)  In evaluating a Market Neutral manager's ability to effectively manage 
a Short portfolio one should consider three factors.  First, is the manager 
dealing with an experienced Prime Broker who can produce an adequate supply 
of stocks to Short.  Second, does the manager have enough assets (and hence 
fee income) Shorted so that he can economically devote enough resources to 
analyzing Short stocks as well as Long stocks.  And third, is the analysis of 
overvalued stocks a natural result of the manager's investment process or 
does it require different people, process, and resources?

                                      GLOSSARY
                                          
Accommodative Trading: A system which allows institutional buyers and sellers 
of stock to electronically present Rosenberg with their "interest" lists each 
morning.  Any matches between the inventory which the brokers have presented 
and Rosenberg's own recommended trades are signaled to Rosenberg's traders.  
Since the broker is doing agency business and has a client on the other side 
of the trade, Rosenberg expects that the broker will be accommodative in the 
price. Rosenberg's objective in using this match system is to execute most 
trades so as to minimize market impact.

AIMR Standards: Standards of performance reporting set by the Association for 
Investment Management and Research.

Alpha: The "risk-adjusted expected return" or the return in excess of what 
would be expected from a diversified portfolio with the same systematic risk. 
 When applied to stocks, alpha is essentially synonymous with misvaluation: a 
stock with a positive alpha is viewed as undervalued relative to other stocks 
with the same systematic risk, and a stock with a negative alpha is viewed as 
overvalued relative to other stocks with the same systematic risk.  When 
applied to portfolios, alpha is a description of expected extraordinary 
reward due to the skill of the manager.  If used in the context of the past 
then alpha is interpreted as the difference between the historical 
performance for a period and what would have been earned with a diversified 
market portfolio at the same level of systematic risk over that period.

BARRA: A consulting firm that provides statistical and risk analyses.

Benchmark: An index or measure of performance with which a particular 
portfolio is compared in order to measure relative performance and/or risk 
exposures.

Beta: Measures changes in an asset's return in relation to changes in the 
return of a broad portfolio of assets or the "market."

Core Portfolio: A portfolio invested primarily in large U.S. stocks.

Correlation: A statistical term giving the strength of the linear 
relationship between two random variables.  It is a pure number, ranging from 
- -1 to +1: +1 is a perfect positive linear relationship; -1 is a perfect 
negative linear relationship.

Equal-Weighted: Making equal dollar investments in each of the stocks in a 
portfolio.

Equitized: Adding back to a market neutral strategy the risk and return of an 
asset class through the use of index futures, options on index futures, and 
swaps.

Equitized Market Neutral: An investment strategy which uses equity index 
futures, options, swaps, etc.  to add back the risk and return from an equity 
index to a market neutral portfolio.  For example, the Barr Rosenberg Double 
Alpha Market Fund will hold S&P 500 Index futures options, swaps, etc.  along 
with shares of the Barr Rosenberg Market Neutral Fund to provide investors 
with the additional risk and return of being invested in the S&P 500 in 
addition to any risk and return provided by the Barr Rosenberg Market Neutral 
Fund.

IBES - Institutional Broker Estimate Service: A service which collects and 
publishes earnings forecasts from institutional analysts.

Hedge: Taking two positions simultaneously in two different assets in order 
to reduce risk.  Also loosely used to describe any strategy using leverage or 
short selling.
    


                                       A-99

Long (Portfolio; Positions): Stocks which are purchased for the portfolio 
(often with the expectation that they are currently undervalued).

Market Neutral (Equity): An investment strategy which simultaneously buys a 
long portfolio and sells a short portfolio in order to neutralize the impact 
of the overall (equity) market on the combined (long and short) portfolio's 
return.

Normalized Standard Deviation: This term is used to refer to the scaling of 
risk indices.  It involves setting the zero point and scale of measurement 
for the variable.  An example might be taken from temperature, where the 
centigrade scale is standardized by setting zero at the freezing point of 
water and establishing the scale (the centigrade degree), so that there are 
100 units between the freezing point of water and the boiling point of water. 
Standardization for risk indices sets the zero value at the 
capitalization-weighted mean of the companies in the universe, and sets the 
scale so that one unit equals one cross-sectional standard deviation of that 
variable among our entire universe of stocks.

Optimizer/Optimized/Optimization: A computer program that uses complex 
piece-wise linear functions to approximate a quadratic function and optimize 
the total portfolio trade-off between risk and return subject to any specific 
constraints or targets.

Portable Alpha: An investment technique that applies the excess return or 
alpha earned from stock selection to another asset class by using index 
futures.

Prime Broker: The broker who facilitates a short sale by arranging for the 
borrowing of shares of a stock and being responsible for the regulatory, 
accounting and fiduciary requirements involving the short sale.

Quantitative: A term which describes an investment approach which tends to 
rely on hard financial data using a disciplined systematic analysis for stock 
selection compared to an approach that tends to rely on subjective judgements 
and soft information.

Regression: A statistical technique that measures the correlation between two 
variables.

Residual Common Factor Risk: That portion of a stock's risk that is related 
to a subgroup of the broad asset class.  An example would be industry-related 
risk.

Residual Specific Risk: That portion of a stock's risk that is unique to that 
stock or company.  An example would be the risk associated with the quality 
of the company's management team.

Risk: The uncertainty of investment outcomes.  Technically, the term RISK is 
used to define all uncertainty about the mean outcome, including both upside 
and downside possibilities.  Thus, in contrast to the layperson, who would 
think of the downside outcomes as risk and of the upside outcome as 
potential, a measure of total variability in both directions is typically 
used to summarize risk. The more intuitive concept for risk measurement is 
the standard deviation of the distribution, a natural measure of spread.  
Variance, the square of the standard deviation, must be used in comparing 
independent elements of risk.

Risk Index: A variable computed for each asset, such that the variable 
determines the asset's exposure to a common factor.  Risk indices include 
market variability, earnings variability, low valuation and unsuccess, 
immaturity and smallness, growth orientation, and financial risk.  In each 
case, a higher value of the index implies a company that is more strongly 
exposed to the common factor.

ROE Reversion: Return on Equity (ROE) is a common measure of company 
profitability.  Reversion relates to the notion that in competitive economies 
there is tremendous pressure on unusually high or low company earnings to 
move back in line with the economy-wide average.

Rosenberg: Also referred to as RIEM, Rosenberg Institutional Equity 
Management, or the Manager.

Rosenberg Market Neutral Strategy Portfolio: The composite of all U.S. 
accounts managed by Rosenberg employing a strategy using offsetting 
long/short equity holdings and is weighted by the value of each account.  As 
of December 31, 1997, there were nine accounts in such composite.  This 
composite does not include the Barr Rosenberg Market Neutral Fund prior to 
December 31, 1997 since the Barr Rosenberg Market Neutral Fund began 
operations in December, 1997 and was not fully invested as of December 31, 
1997.

Rosenberg (Rosenberg's) Market Neutral Strategy (Composite): Rosenberg's 
performance net of 2% annual fees of all U.S. accounts employing a strategy 
using offsetting long/short equity holdings and is weighted by the value of 
each account.  As of December 31, 1997, there were nine accounts in such 
composite. This composite does not include the Barr Rosenberg Market Neutral 
Fund prior to December 31, 1997 since the Barr Rosenberg Market Neutral Fund 
began operations in December, 1997 and was not fully invested as of December 
31, 1997. Performance calculations meet AIMR standards.

Sharpe Ratio: A ratio equal to the squared mean excess return divided by the 
variance of return.  When an investment portfolio is constructed over a wide 
range of independent opportunities, the Sharpe ratio for the optimum total 
portfolio is the sum of the Sharpe ratios for the separate opportunities.  
Thus the Sharpe ratio is a measure of reward per unit of risk.

S&P 500 (Index): An index of 500 (generally larger) companies with the 
holdings proportional to the market value of each of the companies in the 
Index (capitalization weighted).

Short Executions: The process of implementing a desired short sale.  Short 
sales can only be executed after there has been a positive change in the 
price of the stock to be shorted.

Short (Portfolio; Positions): Stocks which are borrowed and sold with the 
expectation that the borrowed shares can be replaced in the future with 
shares purchased at a lower price.

Shorting: The act of borrowing (creating a liability) and then selling a 
stock with the obligation of returning that stock to the lender some time in 
the future.

Short Squeeze: Used to describe the potential risk when a short seller has 
borrowed stock and must replace it in the future.  However, when the short 
seller attempts to buy the stock, there are few sellers relative to the 
demand and the price (and potential liability) of the stock shorted increases 
significantly.

Short Stock Rebate: Return earned by investing the cash generated by the 
short positions and is generally equal to the federal funds rate, less a 
small fee charged by the prime broker.

Standard Deviation: A statistical term which measures the spread or 
variability of a probability distribution.  The standard deviation is the 
square root of variance.  Its intuitive meaning is best seen in a simple, 
symmetrical distribution, such as the normal distribution, where 
approximately two thirds of all outcomes fall within (plus or minus) 1 
standard deviation of the mean and approximately 95 percent of all outcomes 
fall within (plus or minus) 2 standard deviations.

Survivorship Bias: A distortion in the results of a statistical analysis that 
results from the failure to adequately account for the fact that the sample 
at the end of the period does not include those companies that failed or went 
bankrupt and are no longer in the sample.

Systematic Risk: That portion of an asset's risk that is related to the risk 
of the overall asset class.

T-BILLS: 90 day U.S. government treasury bills.

Tracking Error: The annual standard deviation of the alpha or value added.  
It is a measure of how closely the portfolio tracks the benchmark.

Variance: A statistical term for the variability of a random variable about 
its mean.  The variance is defined as the expected squared deviation of the 
random variable from its mean - that is, the average squared distance between 
the mean value and the actually observed value of the random variable.  When 
a portfolio includes several independent elements of risk, the variance of 
the total arises as a summation of the variances of the separate components.

Yield: The return on a security or portfolio in the form of cash payments.  
Most yield comes from dividends on equities, coupons on bonds, or interest on 
mortgages.

Item 27. INDEMNIFICATION.
   
         Article VIII of the Registrant's Second Amended and Restated Agreement
and Declaration of Trust reads as follows (referring to the Registrant as the
"Trust"):
    
                                     ARTICLE VIII
         Indemnification

         SECTION 1.  TRUSTEES, OFFICERS, ETC.  The Trust shall indemnify each
of its Trustees and officers (including persons who serve at the Trust's request
as directors, officers or trustees of another organization in which the Trust
has any interest as a shareholder, creditor or otherwise) (hereinafter referred
to as a "Covered Person") against all liabilities and expenses, including but
not limited to amounts paid in  satisfaction of judgments, in compromise or as
fines and penalties, and counsel fees reasonably incurred by any Covered Person
in connection with the defense or disposition of any action, suit or other
proceeding, whether civil or criminal, before any court or administrative or
legislative body, in which such Covered Person may be or may have been involved
as a party or otherwise or with which such Covered Person may be or may have
been threatened, while in office or thereafter, by reason of being or having
been such a Covered Person except with respect to any matter as to which such
Covered person shall have been finally adjudicated in any such action, suit or
other proceeding to be liable to the Trust or its Shareholders by reason of
wilful misfeasance, bad faith, gross negligence or reckless disregard of the
duties involved in the conduct of such Covered Person's office.  Expenses,
including counsel fees so incurred by any such Covered Person (but excluding
amounts paid in satisfaction of judgments, in compromise or as fines or
penalties), shall be paid from time to time by the Trust in advance of the final
disposition of any such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such Covered Person to repay amounts so paid to
the Trust if it is ultimately determined that indemnification of such expenses
is not authorized under this Article, provided, however, that either (a) such
Covered Person shall have provided appropriate security for such undertaking,
(b) the Trust shall be insured against losses arising from any such advance
payments or (c) either a majority of the disinterested Trustees acting on the
matter (provided that a majority of the disinterested Trustees then in office
act on the matter), or independent legal counsel in a written opinion, shall
have determined, based upon a review of readily available facts (as opposed to a
full trial type inquiry) that there is reason to believe that such Covered
Person will be found entitled to indemnification under this Article.

         SECTION 2.  COMPROMISE PAYMENT.  As to any matter disposed of (whether
by a compromise payment, pursuant to a consent decree or otherwise) without an
adjudication by a court, or by any other body before which the proceeding was
brought, that such Covered Person is liable to the Trust or its Shareholders by
reason of wilful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of his or her office, indemnification
shall be provided if (a) approved, after notice that it involves such
indemnification, by at least a majority of the disinterested Trustees acting on
the matter (provided that a majority of the disinterested Trustees then in
office act on the matter) upon a determination, based upon a review of readily
available fact (as opposed to a full trial type inquiry) that such Covered
Person is not liable to the Trust or its Shareholders by reason of wilful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his or her office, or (b) there has been obtained an
opinion in writing of independent legal counsel, based upon a review of readily
available facts (as opposed to a full trial type inquiry) to the effect that
such indemnification would not protect such Person against any liability to the
Trust to which he would otherwise be subject by reason of wilful misfeasance,
bad faith, gross negligence or reckless disregard of the duties involved in the
conduct of his office.  Any approval pursuant to this Section shall not prevent
the recovery from any Covered Person of any amount paid to such Covered Person
in accordance with this Section as indemnification if such Covered Person is
subsequently adjudicated by a court of competent


                                         -4-
<PAGE>

jurisdiction to have been liable to the Trust or its Shareholders by reason of
wilful misfeasance, bad faith, gross negligence or reckless disregard of the
duties involved in the conduct of such Covered Person's office.

         SECTION 3.  INDEMNIFICATION NOT EXCLUSIVE.  The right of
indemnification hereby provided shall not be exclusive of or affect any other
rights to which such Covered Person may be entitled.  As used in this Article
VIII, the term "Covered Person" shall include such person's heirs, executors and
administrators and a "disinterested Trustee" is a Trustee who is not an
"interested person" of the Trust as defined in Section 2(a)(19) of the
Investment Company Act of 1940, as amended, (or who has been exempted from being
an "interested person" by any rule, regulation or order of the Commission) and
against whom none of such actions, suits or other proceedings or another action,
suit or other proceeding on the same or similar grounds is then or has been
pending.  Nothing contained in this Article shall affect any rights to
indemnification to which personnel of the Trust, other than Trustees or
officers, and other persons may be entitled by contract or otherwise under law,
nor the power of the Trust to purchase and maintain liability insurance on
behalf of any such person; provided, however, that the Trust shall not purchase
or maintain any such liability insurance in contravention of applicable law,
including without limitation the 1940 Act.

         SECTION 4.  SHAREHOLDERS.  In case any Shareholder or former
Shareholder shall be held to be personally liable solely by reason of his or her
being or having been a Shareholder and not because of his or her acts or
omissions or for some other reason, the Shareholder or former Shareholder (or
his or her heirs, executors, administrators or other legal representatives or in
the case of a corporation or other entity, its corporate or other general
successor) shall be entitled to be held harmless from and indemnified against
all loss and expense arising from such liability, but only out of the assets of
the particular series of Shares of which he or she is or was a Shareholder."

                            BARR ROSENBERG SERIES TRUST
                                          
      PLAN PURSUANT TO RULE 18f-3(d) UNDER THE INVESTMENT COMPANY ACT OF 1940
      -----------------------------------------------------------------------
                                          
                              Effective August 5, 1996
                       Amended and Restated December 8, 1997

     WHEREAS, the Board of Trustees of Barr Rosenberg Series Trust (the 
"TRUST") has considered the following amended and restated multi-class plan 
(the "PLAN") under which the Trust may offer multiple classes of shares of 
its now existing and hereafter created series pursuant to Rule 18f-3 (the 
"RULE") under the Investment Company Act of 1940 (the "1940 ACT"); and

     WHEREAS, a majority of the Trustees of the Trust and a majority of the 
Trustees who are not interested persons of the Trust have found the Plan, as 
proposed, to be in the best interests of each class of shares of each series 
of the Trust individually and the Trust as a whole.

     NOW, THEREFORE, the Trust hereby approves and adopts the following Plan 
pursuant to the Rule.

                                       THE PLAN

     Each now existing and hereafter created series ("FUND")(1) of the Trust 
may from time to time issue one or more of the following classes of shares: 
Institutional shares, Adviser shares, Select shares and Investor shares.  
Each class is subject to such investment minimums and other conditions of 
eligibility as are set forth in the Trust's prospectuses, each as from time 
to time in effect (each, a "PROSPECTUS").  The differences in expenses among 
these classes of shares, and the conversion and exchange features of each 
class of shares, are set forth below in this Plan, which is subject to 
change, to the extent permitted by law and by the Agreement and Declaration 
of Trust and By-laws of the Trust, as amended from time to time, by action of 
the Board of Trustees of the Trust.

CLASS CHARACTERISTICS

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

           (1)    The current Funds of the Trust are the U.S. Small 
Capitalization Series, the International Small Capitalization Series, the 
Japan Series, the Barr Rosenberg Market Neutral Fund and the Barr Rosenberg 
Double Alpha Market Fund.


                                      -3-

<PAGE>

     Institutional, Adviser, Select and Investor shares of a Fund represent 
interests in the assets of such Fund and have identical dividend and 
liquidation rights.  The classes differ materially only with respect to (i) 
the level of shareholder service fee ("SERVICE FEE"), if any, borne by each 
class, and (ii) the level of distribution fee ("DISTRIBUTION FEE"), if any, 
borne by each class. Service Fees are paid for services rendered and expenses 
borne in connection with personal services rendered to shareholders of a 
class and the maintenance of shareholder accounts.  Service Fees are paid 
pursuant to Servicing Agreement(s) between the Trust and appropriate 
shareholder servicing agent(s) and under related plans (each a "SERVICE 
PLAN") for  applicable classes. Distribution Fees are paid in connection with 
services and expenses primarily intended to result in the sale of shares 
pursuant to a Distributor's Contract between the Trust and Barr Rosenberg 
Funds Distributor, Inc., the Funds' distributor (the "DISTRIBUTOR"), and 
under a separate plan (each a "DISTRIBUTION PLAN") for each applicable class 
adopted by the Trust pursuant to Rule 12b-1 under the 1940 Act.  

     (1) INSTITUTIONAL SHARES are sold without any initial or deferred sales 
charges and are not subject to any ongoing Distribution Fees or Service Fees.

     (2) ADVISER SHARES are sold without any initial or deferred sales 
charges and are not subject to any ongoing Distribution Fees, but are subject 
to a Service Fee at an annual rate with respect to a Fund equal to 0.25% of 
such Fund's average daily net assets attributable to Adviser shares.

     (3) SELECT SHARES are sold without any initial or deferred sales 
charges, but are subject to a Service Fee at an annual rate with respect to a 
Fund equal to 0.25% of such Fund's average daily net assets attributable to 
Select shares. Select shares are also subject to a Distribution Fee.  The 
Distribution Plan for Select shares permits a Fund to pay the Distributor up 
to 0.50% per annum of the Fund's average daily net assets attributable to 
Select shares.  However, the Distributor's Contract currently provides that 
the Distributor will be paid 0.25% per annum of a Fund's average daily net 
assets attributable to Select shares. 

     (4) INVESTOR SHARES are sold without any initial or deferred sales 
charges, but are subject to a Service Fee at an annual rate with respect to a 
Fund equal to 0.25% of such Fund's average daily net assets attributable to 
Investor shares.  Investor shares are also subject to a Distribution Fee.  
The Distribution Plan for Investor shares permits a Fund to pay the 
Distributor up to 0.50% per annum of the Fund's average daily net assets 
attributable to Investor shares.  However, the Distributor's Contract 
currently provide that the Distributor will be paid 0.25% per annum of a 
Fund's average daily net assets attributable to Investor shares. 

EXPENSE ALLOCATIONS

     Institutional, Adviser, Select and Investor shares pay the expenses 
associated with their different distribution and/or shareholder servicing 
arrangements.  Each class may, at the

                                      -4-

<PAGE>

Trustees' discretion, also pay a different share of other expenses, not 
including advisory or custodial fees or other expenses related to the 
management of the Trust's assets, if these expenses are actually incurred in 
a different amount by that class, or if the class receives services of a 
different kind or to a different degree than the other classes ("CLASS 
EXPENSES").  All other expenses will be allocated to each class on the basis 
of the net asset value of that class in relation to the net asset value of a 
particular Fund attributable to that class. 

EXCHANGE FEATURES / CONVERSIONS

     Shares of any particular class of a Fund may be exchanged only for 
shares of the same class of another Fund or, if a Fund does not offer the 
same class of shares, then the class of shares with the lowest expenses that 
a given shareholder is eligible to purchase.  There is no sales charge on 
exchanges.  A shareholder may not exchange shares of a class of one Fund for 
shares of the same class of another Fund that is not qualified for sale in 
the state of the shareholder's residence.  Although the Trust has no current 
intention of terminating or modifying the exchange privilege, it reserves the 
right to do so at any time.  Except as otherwise permitted by regulations of 
the Securities and Exchange Commission, the Trust will give 60 days' advance 
notice to shareholders of any termination or material modification of the 
exchange privilege.  All exchanges will be made based on the respective net 
asset values next determined following receipt of the request by the Funds.

     The Trust does not currently offer any automatic conversion feature 
among the classes.

DIVIDENDS/DISTRIBUTIONS

     Each Fund intends to pay out as dividends substantially all of its net 
investment income (which comes from dividends and any interest it receives 
from its investments and net realized short-term capital gains).  Each Fund 
also intends to distribute substantially all of its net realized long-term 
capital gains, if any, after giving effect to any available capital loss 
carryover. Dividends paid by the Funds with respect to Institutional, 
Adviser, Select and Investor shares, to the extent any dividends are paid, 
will be calculated in the same manner, at the same time, and will be in the 
same amount, except that any Service Fee or Distribution Fee charged to a 
particular class will be borne solely by such class and, if applicable, at 
the Trustees discretion, Class Expenses relating to a particular class may be 
borne exclusively by that class.

VOTING RIGHTS

     Each class of shares of each Fund has identical voting rights except 
that each class has exclusive voting rights on any matter submitted to 
shareholders that relates solely to that class, and has separate voting 
rights on any matter submitted to shareholders in which the interests of

                                      -5-

<PAGE>

one class differ from the interests of any other class.  Each class of shares 
has exclusive voting rights with respect to matters pertaining to any 
Distribution Plan or Service Plan applicable to that class.  All classes of 
shares of a Fund will vote together, except with respect to any Distribution 
Plan or Service Plan applicable to a class or when a class vote is required 
by the 1940 Act.

RESPONSIBILITIES OF THE TRUSTEES

     On an ongoing basis, the Trustees will monitor the Trust for the 
existence of any material conflicts among the interests of the classes of 
shares.  The Trustees shall further monitor on an ongoing basis the use of 
waivers or reimbursement of expenses by the Manager to guard against 
cross-subsidization between classes.  The Trustees, including a majority of 
the independent Trustees, shall take such action as is reasonably necessary 
to eliminate any such conflict that may develop. 

REPORTS TO THE TRUSTEES

     The Manager and/or the Administrator will be responsible for reporting 
any potential or existing conflicts among the classes of shares to the 
Trustees.

                       CUSTODY FEES AND TRANSACTION CHARGES

     All fees and charges set forth in this Exhibit E shall be calculated and 
paid in the manner provided in Article XII above. The Barr Rosenberg Double 
Alpha Market Fund shall pay Custodian the following fees for assets maintained 
by such Portfolio in the Custody Account and charges for transactions by such 
Portfolio, all such fees and charges to be payable monthly:

     (1) an annual fee consisting of the total of 0.02% (2 basis points) per 
annum of the value of the first $50 million of assets in the Custody Account of
such Portfolio, 0.01% (1 basis points) per annum of the next $150 million of 
such assets and 0.005% (1/2 basis point) per annum of the amount of such 
assets in excess of $200 million;

     (2)  a transaction charge for each repurchase transaction in the Custody 
Account of such Portfolio which represents a cash sweep investment for such 
Portfolio's account, computed at a rate of 0.10% (ten basis points) per annum 
on the amount of the purchase price paid by such Portfolio in such repurchase 
transaction;

     (3)  A charge of $10 for each "free" transfer of funds from the 
Custody Account of such Portfolio; and

     (4)  a service charge for each holding of securities or other assets of 
such Portfolio that are sold by way of private placement or in such other 
manner as to require services by Custodian which in its reasonable judgment 
are materially in excess of those ordinarily required for the holding of 
publicly traded securities in the United States.
