<PAGE>
                       INVESTMENT OBJECTIVE AND POLICIES
 
   
    The investment objective of the 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 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, the Fund attempts to cancel out the effect of general stock
market movements on the Fund's performance. It is expected that the Fund can
achieve a positive return if the Fund's long portfolio outperforms the Fund's
short portfolio. Conversely, it is expected that the Fund will incur losses if
the Fund's long portfolio underperforms the Fund's short portfolio. 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
characteristics 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. It is currently expected
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 preceding sentence, the 200 stocks principally traded in the markets of
the United States with the largest market capitalizations are considered large
capitalization stocks, the next 800 largest stocks are considered
mid-capitalization stocks and all other stocks are considered small
capitalization stocks. Stocks of companies with relatively small market
capitalizations tend to be less liquid and more volatile than stocks of
companies with relatively large market capitalizations.
    
 
   
    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 various risks, including the risk of poor stock selection by the
Manager. There can be no assurance that the Manager will successfully take 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, because
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. Moreover, an investment in the Fund is different from an investment
in 3-month U.S. Treasury Bills because Treasury Bills are backed by the full
faith and credit of the U.S. Government, Treasury Bills have a fixed rate of
return, investors in Treasury Bills do not bear the risk of losing their
investment. and an investment in the Fund is more volatile than an investment in
Treasury Bills.
    
 
   
    To meet margin requirements related to short sales, redemption requests, or
for investment purposes, 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.
    
 
                                       4
<PAGE>
    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.
 
               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 the Fund's portfolio. Investment in shares of the Fund is more
volatile and risky than some other forms of investment. In addition, it is
possible that the Fund's long positions will decline in value at the same time
that the value of securities sold short increases, thereby increasing the
potential for loss of the Fund. 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 Fund. Short-term gains are
ordinarily taxed to shareholders at ordinary income tax rates, thereby
increasing the amount of taxes payable by shareholders.
    
 
   
    RISKS OF SHORT SALES.  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. The 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. The Fund may realize a gain if the security declines in price between
those dates. There can be no assurance that the Fund will be able to close out a
short position at any particular time or at an acceptable price. During the time
the Fund is short a security it is subject to the risk that the lender will
terminate the loan at a time when the Fund is unable to borrow the same security
from another lender, in which event the Fund may be "bought in" at the price
required to purchase the security to close out the short position. Although the
Fund's gain is limited to the amount at which it sold a security short, its
potential loss is limited only by the maximum attainable price of the security
less the price at which the security was sold. Until the security sold short is
replaced, the Fund is required to repay the lender any dividends or interest
that accrue during the period of the loan. To borrow the security, the Fund also
may be required to pay a premium. The Fund also will incur transaction costs in
effecting short sales. The amount of any gain resulting from a short sale will
be decreased, and the amount of any loss increased, by the amount of premiums,
dividends, interest or expenses the Fund may be required to pay in connection
with a short sale. Until the 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, the Fund may not
receive any payments (including interest) on collateral deposited with such
broker or custodian. The Fund 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 the Fund's net assets. The 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.
    
 
    SPECIAL CONSIDERATIONS OF FOREIGN INVESTMENTS.  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,
 
                                       5
<PAGE>
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 may be less liquid and at times more volatile than securities of
comparable U.S. issuers.
 
    REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements, by
which the 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 Fund 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, the Fund
would attempt to exercise rights with respect to the underlying security,
including possible disposition in the market. However, the Fund may be subject
to various delays and risks of loss, including possible declines in the value of
the underlying security during the period while the Fund seeks to enforce its
rights thereto and inability to enforce rights and the expenses involved in
attempted enforcement.
 
    LOANS OF PORTFOLIO SECURITIES.  The 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 of the securities lent. The borrower pays to the
Fund an amount equal to any dividends or interest received on the securities
lent. When the collateral is cash, the Fund 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, the 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. The 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.  The 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 the Fund has
valued such securities, so long as no more than 15% of the 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, the 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 the 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
Fund will exceed 150%. It is, however, impossible to predict portfolio turnover
in future years. High portfolio turnover involves correspondingly greater
brokerage commissions or dealer markup and other transaction costs, which will
be borne directly by the 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 OBJECTIVE AND POLICIES.  Except as explicitly described
otherwise, the investment objective and policies of the Fund may be changed
without shareholder approval.
 
   
               PERFORMANCE INFORMATION OF MARKET NEUTRAL ACCOUNTS
    
 
   
    Rosenberg Institutional Equity Management also serves as the manager of
other accounts (the "Market Neutral Accounts") that have investment objectives,
policies and strategies that are substantially similar to those of the Fund. The
information below should not be considered a prediction of the future
performance of the Fund. The performance of the 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 as the Fund
and has been adjusted to give effect to the estimated annualized expenses
(without giving effect to any expense waivers or reimbursements) of the Fund
during its first fiscal year. All but one of the Market Neutral Accounts were
not registered under the 1940 Act and Subchapter M of the Internal Revenue Code
(the "Code") and therefore were not subject to certain investment restrictions
imposed by the 1940 Act. If those Market Neutral Accounts had been registered
under the 1940 Act or subject to Subchapter M of the Code, their performance and
the composite performance might have been adversely affected. In addition,
separate account fees and changes will be levied against the assets of the Fund
and would have adversely affected the performance of the Market Neutral Accounts
if such fees and charges had been levied against the assets of these accounts.
The following table shows the average annual total return for the one-year,
three-year, five-year and since-inception periods ending March 31, 1998 for a
composite of the Market Neutral Accounts adjusted to give effect to the
estimated annual expenses of the Fund during its first fiscal year. The
following table also shows the average annual total return on 3-month U.S.
Treasury bills for the same periods.

    An investment in the Fund is different from an investment in 3-month U.S.
Treasury Bills because Treasury Bills are backed by the full faith and credit of
the U.S. Government, Treasury Bills have a fixed rate of return, investors in
Treasury Bills do not bear the risk of losing their investment and an investment
in the Fund is more volatile than an investment in Treasury Bills. Giving effect
to the expense limitation of 2.00% on the expenses of the 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 March 31,
1998 for the Market Neutral Accounts would have been 9.03%, 16.74%, 12.18% and
8.08%, 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). Since inception of the market neutral strategy,
however, the Manager has maintained long and short positions of approximately
the same dollar amount within a given capitalization sector. The Fund reserves
the freedom to 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 Fund will have substantially
similar investment objectives, policies and strategies as the Market Neutral
Accounts.
    
 
                            MANAGEMENT OF THE TRUST
 
   
    The Fund is advised and managed by Rosenberg Institutional Equity Management
(the "Manager"), which provides investment advisory services to a number of
institutional investors and several mutual funds.
    
 
KEY PERSONNEL OF THE MANAGER
 
    The biography of each of the General Partners of the Manager is set forth
below. Kenneth Reid is also a Trustee of the Trust.
 
    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 Fund 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 until
his departure in 1986. 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.
    
 
    MARLIS S. FRITZ.  Ms. Fritz is a General Partner of the Manager. She has
primary responsibility for the Manager's new business development and secondary
responsibility for client service.
 
    Ms. Fritz earned a B.S. degree from the University of Michigan, Ann Arbor,
in 1971. After working in life insurance management and sales for seven years,
she entered the investment management business in
 
                                       8

1978 as Marketing Associate with Forstmann-Leff Associates, New York. From 1983
until 1985, she was Vice President, Marketing at Criterion Investment Management
Company, Houston, Texas.
 
    KENNETH REID.  Dr. Reid is a General Partner and Director of Research of the
Manager. His work is focused on the design and estimation of the Manager's
valuation models and he has primary responsibility for analyzing the empirical
evidence that validates and supports the day-to-day recommendations of the
Manager's securities valuation models. Patterns of short-term price behavior
discussed by Dr. Reid as part of his Ph.D. dissertation have been refined and
incorporated into the Manager's proprietary valuation and trading systems.
 
    Dr. Reid earned both a B.A. degree (1973) and an M.D.S. (1975) from Georgia
State University, Atlanta. In 1982, he earned a Ph.D. from the University of
California, Berkeley, where he was awarded the American Bankers Association
Fellowship. From 1981 until June 1986, Dr. Reid worked as a consultant at BARRA
in Berkeley, California. His responsibilities included estimating
multiple-factor risk models, designing and evaluating active management
strategies, and serving as an internal consultant on econometric matters in
finance.
 
   
    GENERAL.  There are 43 professional staff members of the Manager and the
Manager's 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 nineteen individuals with other graduate degrees.
Six members of the staff have been awarded C.F.A. certificates.
    
 
THE OUTSIDE TRUSTEES
 
    William F. Sharpe and Nils H. Hakansson are the 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 is
currently Chairman of Financial Engines Incorporated, an electronic investment
advice company. He has also served as consultant to a number of corporations and
investment organizations. He is also a member of the Board of Trustees of Smith
Breeden Trust, an investment company, and a director at CATS Software and
Stanford Management Company. He received the Nobel Prize in Economic Sciences in
1990.
 
    Professor Hakansson is the Sylvan C. Coleman Professor of Finance and
Accounting at the Haas School of Business, University of California, Berkeley.
He is a former member of the faculty at UCLA as well as at Yale University. At

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 the Fund. In seeking to outperform the Fund's benchmark,
the Manager also attempts to control risk in the 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 the 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.
 
   
    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 the 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 the Fund to sell short an
overvalued stock.
    
 
                                       10
<PAGE>
   
    DECISION PROCESS.  The Manager's decision process is a continuum. Its
research function develops models that 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 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 businesses. The Manager assimilates, checks
and structures 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 Appraisal 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
 
                                       11
<PAGE>
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.
 
    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 attempts to
construct a Fund portfolio that will outperform the relevant benchmark, while
maintaining portfolio risk characteristics similar to those of the Fund's
benchmark. The optimizer simultaneously considers both the results of the
Manager's stock selection models and risk in determining the benefit to a
portfolio of a particular 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.
    
 
    TRADING.  The Manager's trading system aggregates the recommended
transactions for the 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 (also referred to herein 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 that the brokers have presented and the Manager's own
recommended trades are signaled to the Manager's traders. Because 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
    
 
                                       12
<PAGE>
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 disturbances on the Fund's portfolio.
    
 
INDIVIDUALS RESPONSIBLE FOR THE FUND
 
    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 the 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 the 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 the
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 the Fund, the
Manager selects and reviews the 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 the Fund, the right of the Trust to use the
identifying name "Barr Rosenberg" and/or "Rosenberg" may be withdrawn.
 
   
    The Fund will pay all other expenses incurred in the operation of the 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, 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

expenses of meetings of shareholders, expenses of printing and mailing proxy
statements to existing shareholders, expenses of mailing and printing
prospectuses, and insurance premiums.
    
 
   
    In addition, the Fund has agreed to pay the Manager a quarterly management
fee at the annual percentage rate of the 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 the Fund until
further notice to the extent required to limit the total annual operating
expenses (exclusive of nonrecurring account fees, extraordinary expenses and
dividends and interest paid on securities sold short) of the Fund to the
percentage of the Fund's average daily net assets listed in the Expense
Limitation column below. The Manager's fee for management of the 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") serves as the Trust's
transfer agent and provides 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 Fund. The principal address of the Custodian is 101 Carnegie Center,
Princeton, New Jersey 08540.
 
   
YEAR 2000 ISSUES
    
 
   
    Many services provided to the Fund depend on the smooth functioning of
computer systems. Many systems in use today cannot distinguish between the year
1900 and the year 2000. Should any of the service systems fail to process
information properly, that could have an adverse impact on the Fund's operations
and services provided to shareholders. The Manager, Distributor, Servicing
Agent, Transfer Agent, Custodian, Administrator and certain other service
providers to the Fund have reported that each is working toward mitigating the
risks associated with the so-called "year 2000 problem." However, there can be
no assurance that the problem will be corrected in all respects and that the
Fund's operations and services provided to shareholders will not be adversely
affected.

                               PURCHASE OF SHARES
 
    Shares of the Fund may only be purchased by a separate account (a "Separate
Account") of an insurance company (a "Participating Insurance Company"). This
Prospectus should be read in conjunction with the prospectus of the separate
account of the specific insurance product which accompanies this Prospectus.
 
    The offering price for shares of the Fund is the net asset value per share
next determined after receipt of a purchase order. See "Determination of Net
Asset Value." The minimum initial investment in the Fund is $1,000 and the
minimum subsequent investment in the Fund is $500.
 
    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 Trust. For a purchase order of shares to be in "good order"
on a particular day, a check or money order must be received on or before 4:00
p.m., New York Time of that 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.
 
    The Trust reserves the right, in its sole discretion, to suspend the
offering of shares of the 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 the Fund's shares may be made in full or in fractional shares
of the Fund calculated to three decimal places. In the interest of economy and
convenience, certificates for shares will not be issued.
 
                              REDEMPTION OF SHARES
 
    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 Fund at the time of the redemption. 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."
 
    If the Manager determines, in its sole discretion, that it would not be in
the best interests of the remaining shareholders of the Fund to make a
redemption payment wholly or partly in cash, the Fund may pay the redemption
price in whole or in part by a distribution in kind of readily marketable
securities held by the Fund in lieu of cash. Securities used to redeem Fund
shares in kind will be valued in accordance with the Fund's procedures for
valuation described under "Determination of Net Asset Value." Securities
distributed by the Fund in kind will be selected by the Manager in light of the
Fund's objective and will not generally represent a PRO RATA distribution of
each security held in the 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 Fund to dispose of
its securities or to fairly determine the value of its net assets, or during any
other period permitted by the Securities and Exchange Commission for the
protection of investors.

<PAGE>
                        DETERMINATION OF NET ASSET VALUE
 
    The net asset value of each class of shares of the Fund 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 the Fund is determined by
dividing the total market value of the Fund's portfolio investments and other
assets, less any applicable liabilities, by the total outstanding shares of the
Fund.
 
   
    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 for long securities and at the most recent quoted ask price for
securities sold short. 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 for long securities and at the most recent
quoted ask price for securities sold short, 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
 
    The 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). The 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. The 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. The 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 Fund 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
 
    The Fund intends to qualify each year as a regulated investment company
under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code")
and to meet all other requirements necessary for it
 
                                       16
<PAGE>
to be relieved of federal income taxes on income and gains it distributes to
insurance company separate accounts. For information concerning federal income
tax consequences for the holders of variable annuity contracts and variable life
insurance policies, contract holders should consult the prospectus of the
applicable separate account.
 
    Internal Revenue Service regulations applicable to variable annuity and
variable life insurance separate accounts generally require that portfolios that
serve as the funding vehicles solely for such separate accounts invest no more
than 55% of the value of their assets in one investment, 70% in two investments,
80% in three investments and 90% in four investments. Alternatively, a portfolio
will be treated as meeting these requirements for any quarter of its taxable
year if, as of the close of such quarter, the portfolio meets the
diversification requirements applicable to regulated investments companies and
no more than 55% of the value of its total assets consists of cash and cash
items (including receivables), U.S. government securities and securities of
other regulated investment companies. The Fund intends to comply with these
requirements.
 
    If the Fund's investments are not "adequately diversified" under these
requirements, income with respect to variable contracts invested in the Fund at
any time during the calendar quarter in which the failure occurred could become
currently taxable to the owners of the variable contracts and income for prior
periods with respect to such contracts also could be taxable, most likely in the
year of the failure to achieve the required diversification. Other adverse tax
consequences also could ensue.
 
    Fund investments in foreign securities may be subject to withholding taxes
at the source on dividend or interest payments. In that case, the Fund's yield
on those securities would be decreased.
 
    The foregoing is a general summary of the federal income tax consequences of
investing in the Fund. Please refer to the prospectus for your separate account
and variable contract for information regarding the federal income tax treatment
of variable contracts in general and of distributions to your separate account
in particular. See "Income Dividends, Distributions and Tax Status" in the
Trust's Statement of Additional Information for more information on taxes.
 
                DESCRIPTION OF THE TRUST AND OWNERSHIP OF SHARES
 
    The Trust is designed to serve as a funding vehicle for insurance company
separate accounts associated with variable annuity contracts and variable life
insurance policies. The Trust presently intends to serve as a funding vehicle
for variable annuity contracts and variable life insurance policies offered by
separate accounts of various life insurance companies. You should consult the
prospectus issued by the relevant insurance company for more information about a
separate account.
 
    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 March 1, 1998,
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. Interests in the Fund are
represented by shares of the 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
 
                                       17
<PAGE>
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.
 
    All shares of the Fund have identical voting rights. Shares are freely
transferable, are entitled to dividends as declared by the Trustees and, in
liquidation of the Fund's portfolio, are entitled to receive the net assets of
such portfolio. 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 by votes cast in person
or by proxy at a meeting of shareholders or by written consent.
 
    The Trust may, in the future, offer shares of the Fund directly to qualified
pension and profit-sharing plans.
 
   
    Although conflicts of interest may potentially arise from the sale of the
Fund's shares to variable annuity contract-owners and variable life insurance
policy-owners of affiliated and unaffiliated insurance companies, the Trust
currently does not foresee any disadvantages to policy-owners and
contract-owners because the Trust offers its shares to separate accounts of
various insurance companies to serve as the investment medium for their variable
products. Nevertheless, the Trustees intend to monitor events in order to
identify any material irreconcilable conflicts of interest which may possibly
arise, and to determine what action, if any, should be taken in response to such
conflicts. If such a conflict were to occur, one or more insurance companies'
separate accounts might be required to withdraw their investments in the Fund.
This might force the Fund to sell portfolio securities at disadvantageous
prices. In addition, under the President's 1999 Budget Proposal, such a
withdrawal may be currently taxable to owners of variable annuity contracts and
variable life insurance policies.
    
 
    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.
 
                               OTHER INFORMATION
 
    The Fund's investment performance may from time to time be included in
advertisements about the Fund. Total return for the Fund is measured by
comparing the value of an investment in the Fund at the beginning of the
relevant period to the redemption value of the investment in the Fund at the end
of such period (assuming immediate reinvestment of any dividends or capital
gains distributions). All data are based on the 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 the
Fund's portfolio and the Fund's operating expenses. Investment performance also
often reflects the risks associated with the Fund's investment objective and
policies. These factors should be considered when comparing the 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.
 
                                       18
<PAGE>
    Performance information presented for the Fund should not be compared
directly with performance information of other insurance products without taking
into account insurance-related charges and expenses payable with respect to
these insurance products. Insurance-related charges and expenses are not
reflected in the Fund's performance information. As a result of such
insurance-related charges and expenses, an investor's return under the insurance
product would be lower.

                          INVESTMENT OBJECTIVE AND POLICIES

     The investment objective and policies of the Barr Rosenberg VIT Market
Neutral Fund (the "Fund") of Barr Rosenberg Variable Insurance Trust (the
"Trust") are summarized on the front page of the Prospectus and in the text of
the Prospectus under the headings "Investment Objective and Policies" and
"General Description of Risks and Fund Investments."

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

     SHORT SALES.  The Fund will 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, the Fund
must borrow the security to make delivery to the buyer.  The 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 the Fund.  Until the
security is replaced, the Fund is required to repay the lender any dividends or
interest that accrue during the period of the loan.  To borrow the security, the
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.
The Fund also will incur transaction costs in effecting short sales.

   
     The 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.  The Fund may 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 the Fund may be required to pay in connection
with a short sale.  There can be no assurance that the Fund will be able to
close out a short position at any particular time or at an acceptable price.
    

                         MISCELLANEOUS INVESTMENT PRACTICES

   
     PORTFOLIO TURNOVER.  A change in securities held by the Fund is known as
"portfolio turnover" and almost always involves the payment by the 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 Fund, and could involve realization
of capital gains that would be taxable when distributed to shareholders of the
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  "Income Dividends, Distributions and Tax
Status" and "Portfolio Transactions."
    


                                         -3-
<PAGE>

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

                              INVESTMENT RESTRICTIONS

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

     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

          (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 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.)

     It is contrary to the present policy of the Fund, 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 the Fund or the Trust, as the case may be, or (2) 67%
or more of the shares of the 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 Fund and the distributions which it may make are
summarized in the Prospectus under the headings "Distributions" and "Taxes." The
Fund intends to qualify each year as a regulated investment company under the
Internal Revenue Code of 1986, as amended (the "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, the 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 the 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 the Fund qualifies for treatment as a
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.

     Section 817(h) of the Code requires that the investments of a segregated
asset account (a "Separate Account") of an insurance company be "adequately
diversified" as provided therein or in accordance with U.S. Treasury Regulations
in order for the account to serve as the basis for variable annuity contracts
("VA contracts") or variable life insurance policies ("VLI policies").


                                         -6-
<PAGE>

The Fund intends to comply with applicable requirements so that the Fund's
investments are "adequately diversified" for this purpose.  Section 817(h) and
the U.S. Treasury Regulations issued thereunder provide the manner in which a
segregated asset account will treat investments in a regulated investment
company for purposes of the diversification requirements.  If the Fund satisfies
certain conditions, a segregated asset account owning shares of the Fund will be
treated as owning multiple investments consisting of the account's proportionate
share of each of the assets of the Fund.  The Fund intends to satisfy these
conditions so that the shares of the Fund owned by a segregated asset account of
an insurance company depositor will be treated as multiple investments.  If,
however, the Fund is not "adequately diversified" within the meaning of Section
817(h) of the Code, the VA contracts and VLI policies supported by the Fund
would not be treated as annuity or life insurance contracts, as the case may be,
for any period (or subsequent period) during which the Fund is not "adequately
diversified."

     As described in the Prospectus under the heading "Distributions," the 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, the 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.

     Assuming that the Separate Accounts meet the requirements of Section 817,
distributions from the Fund will not be subject to federal income tax currently
on dividends or distributions from the Fund.  Each organization or entity should
review its own circumstances and the federal tax treatment of its income.

     To the extent such investments are permissible for the 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.

     Investment in an entity that qualifies as a "passive foreign investment
company" under the Code could subject the Fund to a U.S. federal income tax or
other charge on certain "excess distributions" with respect to the investment
and on the proceeds from the disposition of the investment; however, this tax
can be avoided by making an election to mark such investments to market
annually.  Other elections may also be available.

                       INVESTMENT ADVISORY AND OTHER SERVICES

MANAGEMENT CONTRACT

     As disclosed in the Prospectus under the heading "Management of the Trust,"
under a management contract (a "Management Contract") between the Trust, on
behalf of the 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 the Fund and will make investment decisions on behalf of
the 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 certain bookkeeping and 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


                                         -9-
<PAGE>

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, the Fund has agreed to pay the Manager a
quarterly management fee at the annual percentage rate of the 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 Contract and, if necessary, will bear certain expenses of the
Fund until further notice so that the Fund's total annual operating expenses
(exclusive  of nonrecurring account fees, and extraordinary expenses and
dividends and interest paid on securities sold short) will not exceed the
percentage of the Fund's average daily net assets set forth in the Prospectus.
In addition, the Manager's compensation under the Management Contract is subject
to reduction to the extent that in any year the expenses of the Fund (including
investment advisory fees but excluding taxes, portfolio brokerage commissions
and any distribution expenses paid by a class of shares of the 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.
    

     The 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.

     The 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
Fund.  The Management Contract automatically terminates on assignment, and is
terminable on not more than 60 days' written notice by the Trust to the Manager.

     In addition, the 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," Marlis S. Fritz is 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.

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 Fund's
operations including: (i) general supervision of the operation of the Fund
including coordination of the services performed by the Fund's investment
adviser, 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 Fund; (ii)
general supervision relative to the compilation of data required for the
preparation of periodic reports distributed to the Fund's officers and Board of
Trustees; and (iii) furnishing office space and certain facilities required for
conducting the business of the Fund.  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.  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 Fund's operations.  For these services, the Fund Accountant is
entitled to receive an annual fee of $30,000.
    

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 the Fund.  Upon
instruction, CTC receives and delivers cash and securities of the 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 
PricewaterhouseCoopers LLP, 555 California Street, San Francisco, California 
94104.  PricewaterhouseCoopers 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 Fund 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


                                         -11-
<PAGE>

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 the
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
the 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 the Fund, the
Manager will receive such services from brokers who are expected to handle a
substantial amount of the 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.

<PAGE>

                              TOTAL RETURN CALCULATIONS

     The Fund computes its average annual total return 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

     The calculation of average annual total return assumes that any dividends
and distributions are reinvested immediately, rather than paid to the investor
in cash.  The ending redeemable value (variable "ERV" in the 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 the 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 the Fund's portfolio and the Fund's operating expenses.

PERFORMANCE COMPARISONS

   
     Investors may judge the performance of the Fund by comparing it 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 Fund that appears in a publication such
    

                                         -13-
<PAGE>

as those mentioned above may be included in advertisements, sales literature and
reports to shareholders.  The Fund 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: 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 Fund; (5) 
descriptions of investment strategies for the Fund; (6) descriptions or 
comparisons of various investment products, which may or may not include the 
Fund; (7) comparisons of investment products (including the Fund) 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 the Fund.  The Trust may also include calculations, such as 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 the 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 Variable Insurance Trust" from "Barr
Rosenberg Variable Trust" on March 27, 1998.

     Interests in the Trust's portfolios are currently represented by shares of
one series, the Barr Rosenberg VIT Market Neutral Fund, 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.

     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.

     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 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 is 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


                                         -15-
<PAGE>

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 the
outstanding shares of the Trust.

                          DETERMINATION OF NET ASSET VALUE

     As indicated in the Prospectus, the net asset value of the 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 Independence Day (observed), Labor Day,
Thanksgiving Day Christmas Day, New Year's Day, Martin Luther King, Jr. Day,
Washington's Birthday, Good Friday and Memorial 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 the Fund and for determining the
offering price of such shares are described in the Prospectus.

ITEM 27.  INDEMNIFICATION.

     Article VIII of the Registrant's 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
willful 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 willful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of his or her office,


                                         -3-
<PAGE>

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 facts (as opposed to a full trial type inquiry) that such
Covered Person is not liable to the Trust or its Shareholders by reason of
willful 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
willful misfeasance, bad faith, gross negligence or reckless disregard of the
duties involved in the conduct of his or her 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 jurisdiction to have been liable to the Trust or its Shareholders by
reason of willful 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 1940 Act (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.

         All fees and charges set forth in this Exhibit E shall be calculated

established for the Barr Rosenberg VIT Market Neutral Fund (the "Portfolio")

assets maintained 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 0.04% (4 basis points) per
annum of the first $50 million of assets in the Custody Account of such
Portfolio, 0.02% (2 basis points) per annum of the next $150 million of such
assets and 0.01% (1 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


                                      -36-

in its reasonable judgment are materially in excess of those ordinarily required
for the holding of publicly traded securities in the United States.

                  wishes to add another series of Barr Rosenberg
                  Variable Insurance  Trust to this Agreement, the
                  title of such account shall be appended to this
                  Agreement as a schedule.

         (b)      SECURITY INTEREST.  Customer hereby grants a
                  continuing security interest to Broker in the
                  Collateral in  the Special Custody Account.  To
                  perfect Broker's security interest, Bank will hold
                  the Collateral in  the Special Custody Account,
                  subject to the interest therein of Broker as the
                  pledgee and secured  party thereof in accordance with
                  the terms of this Agreement.  Such security interest

                  released as provided herein.  Bank shall have no
                  responsibility for the  validity or enforceability of
                  such security interest.

                  of Collateral and transactions in the Special Custody Account

         (d)      EXCESS COLLATERAL. Upon the request of Customer, Broker shall
                  Advise Bank and Customer of any excess of Collateral in the
                  Special Custody Account. Such excess shall at Customer's
                  request be transferred therefrom upon Advice from Broker.
                  Customer represents and warrants to Broker that securities
                  included at any time in the Collateral shall be in good
                  deliverable form (or bank shall have the unrestricted power to
                  put such securities into good deliverable form) in accordance
                  with the requirements of such exchanges as may be the primary
                  market or markets for such securities.

         (e)      ACCOUNTS AND RECORDS. Bank will maintain accounts and records
                  for the Collateral in the Special Custody Account as more
                  fully described in sub-paragraph 5(a) below. The Collateral
                  shall at all times remain the property of the Customer subject
                  only to the extent of the interest and rights therein
                  of Broker as the pledgee thereof.

         3.       ORIGINAL AND VARIATION MARGIN ON SHORT SALES

         (a)      SHORT SALES. From time to time, Customer may place orders with
                  Broker for the short sale of securities. Prior to the
                  acceptance of such orders Broker will Advise Customer of
                  Broker's ability to borrow such securities or other properties
                  and acceptance of short sale orders will be contingent upon
                  same.

         (b)      OPEN SHORT SALES BALANCE.  Broker shall, based on the
                  closing market price on each business day,  compute
                  the aggregate net credit or debit balance on
                  Customer's open short sales and advise Customer
                  and/or Customer's designated agent by 11:00 A.M. New
                  York time on the next business day (the
                  "Determination Day") of the amount of the net debit
                  or credit, as the case may be.  If a net debit
                  balance exists on the Determination Day, Customer
                  will cause an amount equal to such net debit  balance
                  to be paid to Broker by the close of business on the
                  Determination Day.  If a net credit  balance exists
                  on the Determination Day, Broker will pay such credit
                  balance to Customer by the  close of business on the
                  Determination Day.  As Customer's open short
                  positions are marked-to- market each business day,
                  payments will be made by or to Customer to reflect
                  changes (if any) in the  credit or debit balances.
                  Broker will charge interest on debit balances, and
                  Broker will pay interest on  credit balances.
                  Balances will be appropriately adjusted when short
                  sales are closed out.

         4.       PLACING ORDERS

         It is understood and agreed that Customer, when placing with Broker any
order to sell short for Customer's account, will designate the order as such and
hereby authorizes Broker to mark such order as being "short", and when placing
with Broker any order to sell long for Customer's account, will designate the
order as such and hereby authorizes Broker to mark such order as being "long".


                                      4
<PAGE>

Any sell order which Customer shall designate as being for long account as above
provided is for securities then owned by Customer and, if such securities are
not then deliverable by Broker from any account of Customer, the placing of such
order shall constitute a representation by Customer that it is impracticable for
Customer then to deliver such securities to Broker but that Customer shall
deliver them by the settlement date or as soon as possible thereafter.

         5.       RIGHTS AND DUTIES OF THE BANK

         (a)      GENERALLY.  The Bank shall receive and hold in the
                  Special Custody Account, as custodian upon the terms
                  of this Agreement, all Collateral deposited and
                  maintained pursuant to the terms of this Agreement
                  and, except as provided in sub-paragraph 5(b) below,
                  shall receive and hold all monies and other property
                  paid, distributed or substituted in respect of such
                  Collateral or realized on the sale or other
                  disposition of such Collateral; provided, however,
                  that the Bank shall have no duty to require any
                  money or securities to be delivered to it or to
                  determine that the amount and form of assets
                  delivered to it comply with any applicable
                  requirements.  Collateral held in the Special Custody
                  Account shall be released only in accordance with this
                  Agreement or as required by applicable law. The Customer
                  warrants its authority to deposit in such account any money,
                  securities and other property received by the Bank. The Bank
                  may hold the securities in the Special Custody Account in
                  bearer, nominee, book entry, or other form and in a depository
                  or clearing corporation, with or without indicating that the
                  securities are held hereunder; provided, however, that all
                  securities held in the Special Custody Account shall be
                  identified on the Bank's records as subject to this Agreement
                  and shall be in a form that permits transfer without
                  additional authorization or consent of the Customer.

         (b)      DIVIDENDS AND INTEREST. Any interest, dividends or other
                  distributions paid with respect to the Collateral held in the
                  Special Custody Account shall be retained therein as
                  additional Collateral.

         (c)      REPORTS.  The Bank shall provide Broker and Customer
                  with written confirmation of each transfer into  and
                  out of the Special Custody Account, in each case as
                  promptly as practical, but in any event not  later
                  than the next business day.  The Bank also shall
                  render to the Broker and the Customer and/or
                  Customer's designated agent a monthly statement of
                  the Collateral held in the Special Custody  Account.
                  In addition, the Bank will advise the Broker and the
                  Customer and/or Customer's  designated agent, upon
                  request of the Broker or Customer, at any time of the
                  type and amount of  Collateral held in the account;
                  provided, however, that the Bank shall have no
                  responsibility for  making any determination as to
                  the value of such Collateral.

                  and responsibilities under this Agreement are as set
                  forth herein.  The Bank shall act only upon receipt
                  of Advice from Broker regarding release or
                  substitution of Collateral.  The Bank shall not be
                  liable or responsible for anything done, or omitted

                  Bank, the terms of the Custodian Agreement entered
                  into thereby shall apply with respect to the

                  Broker,  Broker shall indemnify and hold the Bank
                  harmless with regard to any losses or liabilities of
                  the Bank  (including counsel fees) imposed on or

                  omission of  the Bank in accordance with any Advice,
                  notice or instruction of Broker under this
                  Agreement.  In  matters concerning or relating to
                  this Agreement, the Bank shall not be responsible for
                  compliance  with any statute or regulation regarding
                  the establishment or maintenance of margin credit,
                  including  but not limited to Regulations T or X of
                  the Board of Governors of the Federal Reserve System,
                  or  with any rules or regulations of the Office of
                  the Controller of the Currency (or the Securities and
                  Exchange Commission). With respect to all securities, however
                  registered, it is understood that all voting rights and other
                  rights and powers shall be exercised exclusively by Customer.
                  Bank's only duty with respect thereto shall be to mail to
                  Customer any documents received, including proxy statements
                  and offering circulars, with any proxies for securities
                  registered in a nominee name executed by such nominee. The
                  Bank shall not be liable to any party for any acts or
                  omissions of the other parties to this Agreement.

         (e)      COMPENSATION. Bank shall be paid as compensation for its
                  services pursuant to this Agreement such compensation as may
                  from time to time be agreed upon in writing between Customer
                  and Bank.

         6.       DELIVERY OF COLLATERAL TO BROKER

         In the event of any failure by Customer to timely comply with any
obligation on Customer's part to be performed or observed under this Agreement
or the Customer Agreement, including, but not limited to, the obligation to
maintain Adequate Margin, or in the event of Customer's Insolvency, Broker may
effect a Closing Transaction or buy-in of any securities of which Customer's
account may be short, provided that Broker shall first use reasonable efforts to
(i) give notice to Customer specifying such default (which notice may be by
telegraph, facsimile transmission or hand delivery) and (ii) hold a discussion
with Customer regarding such default and Broker's intended actions in response
thereto. Notwithstanding the foregoing, neither notice nor a discussion shall be
required in the event market conditions render same impracticable in the
reasonable discretion of Broker. In the event of any default 



                                      6
<PAGE>

as aforesaid, after making a reasonable attempt to give notice to and hold a
discussion with Customer (subject to market conditions as set forth above),
Broker shall also have the right to sell any and all Collateral in the Special
Custody Account and to give Advice to Bank to deliver such Collateral free of
payment to Broker, which Advice shall state that, pursuant to this Agreement,
the condition precedent to Broker's right to receive such Collateral free of
payment has occurred. The Bank will provide immediate telephone notice to
Customer of any receipt by Bank of Advice from Broker to deliver Collateral free
of payment, and shall promptly effect delivery of Collateral to Broker. Subject
to applicable requirements of the New York Uniform Commercial Code, such sale or
purchase may be made according to Broker's judgement and may be made at Broker's
discretion, on the principal exchange or other market for such securities, or in
the event such principal market is closed, in a manner commercially reasonable
for such securities.

         7.       LIMITATION OF BROKER LIABILITY

         Broker shall not be liable for any losses, costs, damages, liabilities
or expenses suffered or incurred by Customer as a result of any transaction
executed hereunder, or any other action taken or not taken by Broker hereunder
for Customer's account at Customer's direction or otherwise, except to the
extent that such loss, cost, damage, liability or expense is the result of
Broker's own negligence, recklessness, willful misconduct or bad faith. With
respect to all securities in the Special Custody Account, it is understood that
all voting rights and other rights and powers shall be exercised exclusively by
Customer, and that Broker shall have no responsibilities in connection
therewith, whether pertaining to the delivery of proxy statements or offering
circulars or otherwise.

     Notwithstanding the foregoing, no party to this Agreement shall be liable
for any losses caused directly or indirectly by any inability of such party to
perform occasioned by suspension of trading, wars, civil disturbances, strikes,
natural calamities, labor or material shortages, government restrictions, acts
or omissions of exchanges, specialists, markets, clearance organizations or
information providers, delays in mails, delays or inaccuracies in the
transmission of orders or information, governmental, exchange or self-regulatory
organization laws, rules or actions, or any other causes beyond such party's
control, or for any consequential, incidental, punitive, special or indirect
damages, economic loss or lost profits, even if such party has been advised of
the possibility of such damages or loss.

         8.       CUSTOMER REPRESENTATION

         Customer represents and warrants that the Collateral will not be
subject to any other liens or encumbrances other than those granted to the Bank
under the Custodian Agreement.

         9.       TERMINATION

         Any of the parties hereto may terminate this Agreement by 30 days'

shall not be binding upon any trustee, officer or employee of Barr Rosenberg
Variable Insurance Trust individually, or upon any holder of shares issued by

upon the assets and property of Barr Rosenberg VIT Market Neutral Fund. Such
trustees, officers, employees and holders, when acting in such capacities, shall
not be personally liable under this Agreement, and Broker and Bank shall look
solely to the assets and property of Barr Rosenberg VIT Market Neutral Fund for
the performance of this Agreement thereby and for the payment of any claim

                            TRANSFER AGENCY AGREEMENT

         AGREEMENT made this __ day of October, 1998, between BARR ROSENBERG
VARIABLE INSURANCE TRUST (the "Trust"), a Massachusetts business trust, and
BISYS FUND SERVICES OHIO, INC. ("BISYS"), an Ohio corporation.

         WHEREAS, the Trust desires that BISYS perform certain services for each
series of the Trust (individually referred to herein as a "Fund" and
collectively as the "Funds"); and

         WHEREAS, BISYS is willing to perform such services on the terms and
conditions set forth in this Agreement.

         NOW, THEREFORE, in consideration of the mutual premises and covenants
herein set forth, the parties agree as follows:

         1.     RETENTION OF BISYS.

                The Trust hereby engages BISYS to act as the transfer agent for
the Funds to perform (i) the transfer agent services set forth in Schedule A
hereto (the "Initial Services"), (ii) such special services (the "Special
Services") incidental to the performance of such services as may be agreed to by
the parties from time to time (for such fees as the parties may agree as
aforesaid) and (iii) such additional services (collectively with the Initial
Services and the Special Services, the "Services"), as may be agreed to by the
parties from time to time and set forth in an amendment to said Schedule A (for
such fees as the parties may agree as aforesaid).

                BISYS may, in its discretion, appoint in writing other parties
qualified to perform transfer agency services reasonably acceptable to the Trust
(individually, a "Sub-transfer Agent") to carry out some or all of its
responsibilities under this Agreement with respect to a Fund; provided, however,
that the Sub-transfer Agent shall be the agent of BISYS and not the agent of the
Trust or such Fund, and that BISYS shall be fully responsible for the acts of
such Sub- transfer Agent and shall not be relieved of any of its
responsibilities hereunder by the appointment of such Sub-transfer Agent.

         2.     FEES.

                The Trust shall pay BISYS for the services to be provided by
BISYS under this Agreement in accordance with, and in the manner set forth in,
Schedule B hereto. Fees for any additional services to be provided by BISYS
pursuant to an amendment to Schedule A hereto shall be subject to mutual
agreement at the time such amendment to Schedule A is proposed.

<PAGE>

         3.     REIMBURSEMENT OF EXPENSES.

                In addition to paying BISYS the fees described in Section 2
hereof, the Trust agrees to reimburse BISYS for BISYS' reasonable out-of-pocket
expenses in providing services hereunder, including without limitation, the
following:

                (a)   All freight and other delivery and bonding charges
                      incurred by BISYS in delivering materials to and from the
                      Trust and in delivering all materials to shareholders;

                (b)   All direct telephone, telephone transmission and telecopy
                      or other electronic transmission expenses incurred by
                      BISYS in communication with the Trust, the Trust's
                      investment adviser or custodian, dealers, shareholders or
                      others as required for BISYS to perform the services to be
                      provided hereunder;

                (c)   Costs of postage, couriers, stock computer paper,
                      statements, labels, envelopes, checks, reports, letters,
                      tax forms, proxies, notices or other form of printed
                      material which shall be required by BISYS for the
                      performance of the services to be provided hereunder;

                (d)   The cost of microfilm or microfiche of records or
                      other materials;

                (e)   All systems-related expenses associated with the provision
                      of special reports and services pursuant to Schedule C
                      attached hereto; and

                (f)   Any expenses BISYS shall reasonably incur at the written
                      direction of an officer of the Trust (other than an
                      officer of the Trust who is also an employee of BISYS)
                      thereunto duly authorized.

         4.     EFFECTIVE DATE.

                This Agreement shall become effective as of the date first
written above (the "Effective Date").

         5.     TERM.

                The initial term of this Agreement (the "Initial Term") shall be
for a period commencing on the date first written above and ending on October 1,
1999. Thereafter, it shall be renewed automatically for successive one-year
terms unless written notice not to renew is given by the non-renewing party to
the other party at least 60 days prior to the expiration of the then-current
term; provided, however, that, after the Initial Term, (i) the Trust may
terminate this Agreement at any time, without the payment of a penalty, by a
vote of a majority of the Trust's outstanding voting 


                                       2
<PAGE>

securities (as defined in the 1940 Act) or by vote of a majority of the Trustees
of the Trust on 60 days' written notice to BISYS and (ii) BISYS may terminate
this Agreement at any time, without penalty, on 60 days' written notice to the
Trust; and, provided further, that after such termination, for so long as BISYS,
with the written consent of the Trust, in fact continues to perform any one or
more of the services contemplated by this Agreement or any Schedule or exhibit
hereto, the provisions of this Agreement, including without limitation the
provisions dealing with indemnification, shall continue in full force and
effect. Fees and reasonable out-of-pocket expenses incurred by BISYS but unpaid
by the Trust upon termination of this Agreement shall be immediately due and
payable upon and notwithstanding such termination. BISYS shall be entitled to
collect from the Trust, in addition to the fees and disbursements provided by
Sections 2 and 3 hereof, the amount of all of BISYS' reasonable costs in
connection with BISYS' activities in effecting such termination, including
without limitation, the delivery to the Trust and/or its distributor or
investment adviser and/or other parties, of the Trust's property, records,
instruments and documents, or any copies thereof. To the extent that BISYS may
retain in its possession copies of any Trust documents or records subsequent to
such termination which copies had not been requested by or on behalf of the
Trust in connection with the termination process described above, BISYS will
provide the Trust with reasonable access to such copies; provided, that BISYS
shall be reimbursed for reasonable costs incurred in connection therewith.

                In the event of a material breach of this Agreement by either
party, the non- breaching party shall notify the breaching party in writing of
such breach and, upon receipt of such notice, the breaching party shall have 45
days to remedy the breach. In the event the breach is not remedied within such
time period, the nonbreaching party may immediately terminate this Agreement.

                If, for any reason, other than a material breach of this
Agreement or termination of this Agreement by the Trust after the Initial Term,
BISYS is replaced as transfer agent, or if a third party is added to perform all
or a part of the services provided by BISYS under this Agreement (excluding any
sub-transfer agent appointed by BISYS as provided in Section 1 hereof), then the
Trust shall make a one-time cash payment, as liquidated damages to, BISYS equal
to the balance due BISYS for the remainder of the term of this Agreement,
assuming for purposes of calculation of the payment that the asset level of the
Trust on the date BISYS is replaced, or a third party is added, will remain
constant for the balance of the contract term.

                In the event the Trust is merged into another legal entity in
part or in whole pursuant to any form of business reorganization or is
liquidated in part or in whole prior to the expiration of the Initial Term of
this Agreement, the parties acknowledge and agree that (i) the liquidated
damages provision set forth above shall be applicable in those instances in
which BISYS is not retained to provide transfer agency services and (ii) for
purposes of calculating the payment amount representing liquidated damages, the
number of shareholder accounts within the Trust shall be the greater of: (i) the
number of shareholder accounts at the time the Trust's Board of Trustees
receives notification of an intention on the part of Fund management to effect
such a business reorganization or liquidation; (ii) the number of shareholder
accounts at the time the Trust's Board of Trustees 


                                       3
<PAGE>

formally approves such a business reorganization or liquidation; or (iii) the
number of shareholder accounts on the day prior to the first day during which
assets are transferred by the Trust pursuant to the plan of reorganization or
liquidation. The one-time cash payment referenced above shall be due and payable
on the day prior to the first day during which assets are transferred to the
surviving entity pursuant to the plan of reorganization or liquidation.

                The parties further acknowledge and agree that, in the event the
BISYS ceases to be retained, as set forth above, (i) a determination of actual
damages incurred by the BISYS would be extremely difficult, and (ii) the
liquidated damages provision contained herein is intended to adequately
compensate BISYS for damages incurred and is not intended to constitute any form
of penalty.

         6.     UNCONTROLLABLE EVENTS.

                BISYS assumes no responsibility hereunder, and shall not be
liable for any damage, loss of data, delay or any other loss whatsoever caused
by events beyond its reasonable control.

         7.     LEGAL ADVICE.

                BISYS shall notify the Trust at any time BISYS believes that it
is in need of the advice of counsel (other than counsel in the regular employ of
BISYS or any affiliated companies) with regard to BISYS' responsibilities and
duties pursuant to this Agreement; and after so notifying the Trust, BISYS, at
its discretion, shall be entitled to seek, receive and act upon advice of legal
counsel of its choosing (which counsel shall be reasonably acceptable to the
Trust) and BISYS shall in no event be liable to the Trust or any Fund or any
shareholder or beneficial owner of the Trust for any action reasonably taken
pursuant to such advice.

         8.     INSTRUCTIONS.

                Whenever BISYS is requested or authorized to take action
hereunder pursuant to instructions from a shareholder, or a properly authorized
agent of a shareholder ("shareholder's agent"), concerning an account in a Fund,
BISYS shall be entitled to rely upon any certificate, letter or other instrument
or communication, reasonably believed by BISYS to be genuine and to have been
properly made, signed or authorized by an officer or other authorized agent of
the Trust or by the shareholder or shareholder's agent, as the case may be, and
shall be entitled to receive as conclusive proof of any fact or matter required
to be ascertained by it hereunder a certificate signed by an officer of the
Trust or any other person authorized by the Trust's Board of Trustees or by the
shareholder or shareholder's agent, as the case may be.

                As to the services to be provided hereunder, BISYS may rely
conclusively upon the terms of the Prospectuses and Statement of Additional
Information of the Trust relating to the Funds 


                                       4
<PAGE>

to the extent that such services are described therein unless BISYS receives
written instructions to the contrary in a timely manner from the Trust.

          9.    STANDARD OF CARE; RELIANCE ON RECORDS AND INSTRUCTIONS;
INDEMNIFICATION.

                BISYS shall use its best efforts to ensure the accuracy of all
services performed under this Agreement, but shall not be liable to the Trust
for any action taken or omitted by BISYS in the absence of bad faith, willful
misfeasance, negligence or reckless disregard by it of its obligations and
duties. The Trust agrees to indemnify and hold harmless BISYS, its employees,
agents, directors, officers and nominees from and against any and all claims,
demands, actions and suits, whether groundless or otherwise, and from and
against any and all judgments, liabilities, losses, damages, costs, charges,
reasonable counsel fees and other reasonable expenses of every nature and
character arising out of or in any way relating to BISYS' actions taken or
nonactions with respect to the performance of services under this Agreement or
based, if applicable, upon reasonable reliance on information, records,
instructions or requests given or made to BISYS by a duly authorized
representative of the Trust or the investment adviser and on any records
provided by any fund accountant or custodian thereof; provided that this
indemnification shall not apply to actions or omissions of BISYS, its employees,
agents, directors, officers and nominees in cases of their own bad faith,
willful misfeasance, negligence or reckless disregard by any or all of them of
BISYS' obligations and duties; and further provided that prior to confessing any
claim against it which may be the subject of this indemnification, BISYS shall
give the Trust written notice of and a reasonable opportunity to defend against
said claim in its own name or in the name of BISYS.

                BISYS agrees to indemnify and hold harmless the Trust, its
employees, agents, Trustees, officers and nominees from and against any and all
actions, suits, demands and claims, whether groundless or otherwise, and from
and against any and all judgments, liabilities, losses, damages, costs, charges,
reasonable counsel fees and other expenses of every nature and character arising
out of or in any way relating to BISYS' or its employees', agents', directors',
officers' and nominees' bad faith, willful misfeasance, negligence or reckless
disregard by any or all of them of BISYS' obligations and duties with respect to
the performance of services under this Agreement; provided, that, prior to
confessing any claim against it which may be the subject of this
indemnification, the Trust shall give BISYS written notice of and a reasonable
opportunity to defend against said claim in its own name or in the name of the
Trust.

         The rights hereunder shall include the right to reasonable advances of
defense expenses in the event of any pending or threatened litigation with
respect to which indemnification hereunder may ultimately be merited. In order
that the indemnification provision contained herein shall apply, however, it is
understood that if in any case the indemnifying party may be asked to indemnify
or hold the other party harmless, the indemnifying party shall be fully and
promptly advised of all pertinent facts concerning the situation in question,
and it is further understood that the indemnified party will use all reasonable
care to identify and notify the indemnifying party promptly concerning any
situation which presents or appears likely to present the probability of such a
claim for 


                                       5
<PAGE>

indemnification against the indemnifying party, but failure to do so
in good faith shall not affect the rights hereunder.

                The indemnifying party shall be entitled to participate at its
own expense or, if it so elects, to assume the defense of any suit brought to
enforce any claims subject to this indemnity provision. If the indemnifying
party elects to assume the defense of any such claim, the defense shall be
conducted by counsel chosen by the indemnifying party and satisfactory to the
other party, whose approval shall not be unreasonably withheld. In the event
that the indemnifying party elects to assume the defense of any suit and retain
counsel, the indemnified party shall bear the fees and expenses of any
additional counsel retained by it. If the indemnifying party does not elect to
assume the defense of a suit, it will reimburse the indemnified party for the
reasonable fees and expenses of any counsel retained by the other party.

         10.    RECORD RETENTION AND CONFIDENTIALITY.

                BISYS shall keep and maintain on behalf of the Trust all books
and records which the Trust or BISYS is, or may be, required to keep and
maintain pursuant to any applicable statutes, rules and regulations, including
without limitation Rules 31a-1 and 31a-2 under the Investment Company Act of
1940, as amended (the "1940 Act"), relating to the maintenance of books and
records in connection with the services to be provided hereunder. BISYS further
agrees that all such books and records shall be the property of the Trust and to
make such books and records available for inspection by the Trust or by the
Securities and Exchange Commission (the "Commission") at reasonable times and
otherwise to keep confidential all books and records and other information
relative to the Trust and its shareholders, except when requested to divulge
such information by duly-constituted authorities or court process, or requested
by a shareholder or shareholder's agent with respect to information concerning
an account as to which such shareholder has either a legal or beneficial
interest or when requested by the Trust, the shareholder, or shareholder's
agent, or the dealer of record as to such account.

         11.    REPORTS.

                BISYS will furnish to the Trust and to its properly authorized
auditors, investment advisers, examiners, distributors, dealers, underwriters,
salesmen, insurance companies and others designated by the Trust in writing,
such reports at such times as are prescribed in Schedule C attached hereto, or
as subsequently agreed upon by the parties pursuant to an amendment to Schedule
C.

         12.    RIGHTS OF OWNERSHIP.

                All computer programs and procedures developed to perform
services required to be provided by BISYS under this Agreement are the property
of BISYS. All records and other data except such computer programs and
procedures are the exclusive property of the Trust and all such 


                                       6
<PAGE>

other records and data will be furnished to the Trust in appropriate form as
soon as practicable after termination of this Agreement for any reason.

         13.    RETURN OF RECORDS.

                BISYS may at its option at any time, and shall promptly upon the
Trust's demand, turn over to the Trust and cease to retain BISYS' files, records
and documents created and maintained by BISYS pursuant to this Agreement which
are no longer needed by BISYS in the performance of its services or for its
legal protection. If not so turned over to the Trust, such documents and records
will be retained by BISYS for six years from the year of creation. At the end of
such six-year period, such records and documents will be turned over to the
Trust unless the Trust authorizes in writing the destruction of such records and
documents.

         14.    BANK ACCOUNTS.

                The Trust and the Funds shall establish and maintain such bank
accounts with such bank or banks as are selected by the Trust, as are necessary
in order that BISYS may perform the services required to be performed hereunder.
To the extent that the performance of such services shall require BISYS directly
to disburse amounts for payment of dividends, redemption proceeds or other
purposes, the Trust and Funds shall provide such bank or banks with all
instructions and authorizations necessary for BISYS to effect such
disbursements.

         15.    REPRESENTATIONS OF THE TRUST.

                The Trust certifies to BISYS that: (a) as of the close of
business on the Effective Date, each Fund which is in existence as of the
Effective Date has authorized unlimited shares, and (b) by virtue of its
Agreement and Declaration of Trust, as amended, shares of each Fund which are
redeemed by the Trust may be sold by the Trust from its treasury, and (c) this
Agreement has been duly authorized by the Trust and, when executed and delivered
by the Trust, will constitute a legal, valid and binding obligation of the
Trust, enforceable against the Trust in accordance with its terms, subject to
bankruptcy, insolvency, reorganization, moratorium and other laws of general
application affecting the rights and remedies of creditors and secured parties
and general principles of equity.

         16.    REPRESENTATIONS OF BISYS.

                BISYS represents and warrants that: (a) BISYS has been in, and
shall continue to be in, substantial compliance with all provisions of law,
including Section 17A(c) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), required in connection with the performance of its duties under
this Agreement; and (b) the various procedures and systems which BISYS has
implemented with regard to safekeeping from loss or damage attributable to fire,
theft or any other cause of the blank checks, records, and other data of the
Trust and BISYS' records, data, equipment, facilities and other property used in
the performance of its obligations hereunder are 


                                       7
<PAGE>

adequate and that it will make such changes therein from time to time as are
required for the secure performance of its obligations hereunder.

         17.    INSURANCE.

                BISYS shall notify the Trust should its insurance coverage with
respect to professional liability or errors and omissions coverage be canceled
or reduced. Such notification shall include the date of change and the reasons
therefor. BISYS shall notify the Trust of any material claims against it with
respect to services performed under this Agreement, whether or not they may be
covered by insurance, and shall notify the Trust from time to time as may be
appropriate of the total outstanding claims made by BISYS under its insurance
coverage.

         18.    INFORMATION TO BE FURNISHED BY THE TRUST AND FUNDS.

                The Trust has furnished to BISYS, or will furnish to BISYS
within 90 days following the Effective Date, the following:

         THIS AGREEMENT is made as of this ___ day of October, 1998, by and
between BARR ROSENBERG VARIABLE INSURANCE TRUST, a Massachusetts business trust
(the "Trust"), and BISYS FUND SERVICES OHIO, INC. (the "Administrator"), an Ohio
corporation.

         WHEREAS, the Trust is an open-end management investment company
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), that is authorized to issue series of shares of beneficial interest
("Shares"); and

         WHEREAS, the Trust desires the Administrator to provide, and the
Administrator is willing to provide, management and administrative services to
such series of the Trust as the Trust and the Administrator may agree on
("Portfolios") and as listed on Schedule A attached hereto and made a part of
this Agreement, on the terms and conditions hereinafter set forth;

         NOW, THEREFORE, in consideration of the premises and the covenants
hereinafter contained, the Trust and the Administrator hereby agree as follows:

         ARTICLE 1. RETENTION OF THE ADMINISTRATOR. The Trust hereby engages the
Administrator to act as the administrator of the Portfolios and to furnish the
Portfolios with the management and administrative services as set forth in
Article 2 below. The Administrator hereby accepts such engagement and agrees to
perform the duties set forth below.

         The Administrator shall, for all purposes herein, be deemed to be an

shall have no authority to act for or represent the Trust in any way and shall
not be deemed an agent of the Trust.

         ARTICLE 2. ADMINISTRATIVE SERVICES. The Administrator shall perform or
supervise the performance by others of administrative services in connection
with the operations of the Portfolios, and, on behalf of the Trust, will
investigate, assist in the selection of and conduct relations with custodians,
depositories, accountants, legal counsel, underwriters, brokers and dealers,
corporate fiduciaries, insurers, banks and persons in any other capacity deemed
to be necessary or desirable for the Portfolios' operations. The Administrator
shall provide the Trustees of the Trust with such reports regarding investment
performance as they may reasonably request but shall have no responsibility for
supervising the performance by any investment adviser or sub-adviser of its
responsibilities.

         The Administrator shall provide the Trust with regulatory reporting,
all necessary office space, equipment, personnel, compensation and facilities
(including facilities for meetings of shareholders ("Shareholders") and Trustees
of the Trust) for handling the affairs of the Portfolios and such other services
as the Administrator shall, from time to time, determine to be necessary to
perform its obligations under this Agreement. In addition, at the request of the
Board of Trustees,

                  turnover rate and, if required, portfolio average
                  dollar-weighted maturity;

         (b)      assist Trust counsel with the preparation of prospectuses,
                  statements of additional information, registration statements

                  Federal and state securities law) as may be necessary
                  or desirable to register the Trust's Shares with
                  state securities authorities, monitor the sale of
                  Trust Shares for compliance with state securities
                  laws, and file with the appropriate state securities
                  authorities the registration statements and reports
                  for the Trust and the Trust's Shares and all
                  amendments thereto, as may be necessary or convenient
                  to register and keep effective the Trust and the
                  Trust's Shares with state securities authorities to

         (d)      develop and prepare, with the assistance of the

upon by the parties from time to time. Such services may include performing
internal audit examinations; mailing the annual reports of the Portfolios;
preparing an annual list of Shareholders; and mailing notices of Shareholders'
meetings, proxies and proxy statements, for all of which the Trust will pay the
Administrator's out-of-pocket expenses.

         ARTICLE 3.  ALLOCATION OF CHARGES AND EXPENSES.

         (A) THE ADMINISTRATOR. The Administrator shall furnish at its own
expense the executive, supervisory and clerical personnel necessary to perform
its obligations under this Agreement. The Administrator shall also provide at
its own expense the items which it is obligated to provide under this Agreement,
and shall pay all compensation, if any, of officers of the Trust as well as all
Trustees of the Trust who are affiliated persons of the Administrator or any
affiliated corporation of the Administrator; provided, however, that unless
otherwise specifically provided, the Administrator shall not be obligated to pay
the compensation of any employee of the Trust retained by the Trustees of the
Trust to perform services on behalf of the Trust.

         (B) THE TRUST. The Trust assumes and shall pay or cause to be paid all
other expenses of the Trust not otherwise allocated herein, including, without
limitation, organization costs, taxes, expenses for legal and auditing services,
the expenses of preparing (including typesetting), printing and mailing reports,
prospectuses, statements of additional information, proxy solicitation material
and notices to existing Shareholders, all expenses incurred in connection with
issuing and redeeming Shares, the costs of custodial services, the cost of
initial and ongoing registration of the Shares under Federal and state
securities laws, fees and out-of-pocket expenses of Directors who are not
affiliated persons of the Administrator or the investment adviser to the Trust
or any affiliated corporation of the Administrator or the investment adviser,
insurance, interest, brokerage costs, litigation and other extraordinary or
nonrecurring expenses, and all fees and charges of investment advisers to the
Trust.

         ARTICLE 4.  COMPENSATION OF THE ADMINISTRATOR.

         (A) ADMINISTRATION FEE. For the services to be rendered, the facilities
furnished and the expenses assumed by the Administrator pursuant to this
Agreement, the Trust shall pay to the Administrator compensation at an annual
rate specified in Schedule A attached hereto. Such compensation shall be
calculated and accrued daily, and paid to the Administrator monthly.

                  If this Agreement becomes effective subsequent to the first
day of a month or termination of this Agreement occurs before the last day of a
month, the Administrator's compensation for that part of the month in which this
Agreement is in effect shall be prorated in a manner consistent with the
calculation of the fees as set forth above. Payment of the Administrator's
compensation for the preceding month shall be made promptly.


                                      4
<PAGE>

         (B) SURVIVAL OF COMPENSATION RIGHTS. All rights of compensation under
this Agreement for services performed as of the termination date shall survive
the termination of this Agreement.

         ARTICLE 5. LIMITATION OF LIABILITY OF THE ADMINISTRATOR. The duties of
the Administrator shall be confined to those expressly set forth herein, and no
implied duties are assumed by or may be asserted against the Administrator
hereunder. The Administrator shall not be liable for any error of judgment or
mistake of law or for any loss arising out of any act or omission in carrying
out its duties hereunder, except a loss resulting from willful misfeasance, bad
faith or negligence in the performance of its duties, or by reason of reckless
disregard of its obligations and duties hereunder, except as may otherwise be
provided under provisions of applicable law which cannot be waived or modified
hereby. (As used in this Article 5, the term "Administrator" shall include
directors, officers, employees and other agents of the Administrator as well as
the Administrator itself.) Further, notwithstanding its agreement hereunder to
conduct reviews of each Portfolio's compliance with the requirements of
Subchapter M and Section 817(h) of the Code, the Administrator shall not bear
any responsibility for any Portfolio's failure to comply with such requirements.

         So long as the Administrator acts in good faith and with due 
diligence and without negligence or reckless disregard of its obligations and 
duties hereunder, the Trust assumes full responsibility and shall indemnify 
the Administrator and hold it harmless from and against any and all actions, 
suits and claims, whether groundless or otherwise, and from and against any 
and all losses, damages, costs, charges, reasonable counsel fees and 
disbursements, payments, expenses and liabilities (including reasonable 
investigation expenses) arising directly or indirectly out of the 
administration services described herein or any other service rendered to the 
Trust hereunder. The Administrator agrees to indemnify and hold harmless the 
Trust, its employees, agents, Trustees, officers and nominees from and 
against any and all actions, suits and claims, whether groundless or 
otherwise, and from and against any and all judgments, liabilities, losses, 
damages, costs, charges, payments, reasonable counsel fees and disbursements 
and other expenses of every nature and character (including reasonable 
investigation expenses) arising directly or indirectly out of or in any way 
relating to the Administrator's bad faith, willful misfeasance, negligence or 
reckless disregard by it of its obligations and duties with respect to the 
performance of services under this Agreement. The indemnity and defense 
provisions set forth herein shall indefinitely survive the termination of 
this Agreement.

         The rights hereunder shall include the right to reasonable advances of
defense expenses in the event of any pending or threatened litigation with
respect to which indemnification hereunder may ultimately be merited. In order
that the indemnification provision contained herein shall apply, however, it is
understood that if in any case the indemnifying party may be asked to indemnify
or hold the other party harmless, the indemnifying party shall be fully and
promptly advised of all pertinent facts concerning the situation in question,
and it is further understood that the indemnified party will use all reasonable
care to identify and notify the indemnifying party promptly concerning any
situation which presents or appears likely to present the probability of such a
claim for indemnification against the indemnifying party, but failure to do so
in good faith shall not affect the rights hereunder.


                                      5
<PAGE>

         The indemnifying party shall be entitled to participate at its own 
expense or, if it so elects, to assume the defense of any suit brought to 
enforce any claims subject to this indemnity provision. If the indemnifying 
party elects to assume the defense of any such claim, the defense shall be 
conducted by counsel chosen by the indemnifying party and satisfactory to the 
other party, whose approval shall not be unreasonably withheld. In the event 
that the indemnifying party elects to assume the defense of any suit and 
retain counsel, the indemnified party shall bear the fees and expenses of any 
additional counsel retained by it. If the indemnifying party does not elect 
to assume the defense of a suit, it will reimburse the indemnified party for 
the reasonable fees and expenses of any counsel retained by the other party.

         The Administrator may apply to the Trust at any time for instructions
and may consult counsel for the Trust or its own counsel and with accountants
and other experts with respect to any matter arising in connection with the
Administrator's duties, and the Administrator shall not be liable or accountable
for any action taken or omitted by it in good faith in accordance with such
instructions or with the opinion of such counsel, accountants or other experts.

         Also, the Administrator shall be protected in acting upon any document
which it reasonably believes to be genuine and to have been signed or presented
by the proper person or persons. The Administrator will not be held to have
notice of any change of authority of any officers, employees or agents of the
Trust until receipt of written notice thereof from the Trust.

         ARTICLE 6. ACTIVITIES OF THE ADMINISTRATOR. The services of the
Administrator rendered to the Trust are not to be deemed to be exclusive. The
Administrator is free to render such services to others and to have other
businesses and interests. It is understood that trustees, officers, employees
and shareholders of the Trust are or may be or become interested in the
Administrator, as partners, officers and employees or otherwise and that
partners, officers and employees of the Administrator and its counsel are or may
be or become similarly interested in the Trust, and that the Administrator may
be or become interested in the Trust as a shareholder or otherwise.

         ARTICLE 7. DURATION OF THIS AGREEMENT. The term of this Agreement shall
be as specified in Schedule A hereto.

         ARTICLE 8. ASSIGNMENT. This Agreement shall not be assignable by either
party without the written consent of the other party; provided, however, that
the Administrator may, at its expense and with the written consent of the Trust,
subcontract with any entity or person concerning the provision of the services
contemplated hereunder. The Administrator shall not, however, be relieved of any
of its obligations under this Agreement by the appointment of such subcontractor
and provided further, that the Administrator shall be responsible, to the extent
provided in Article 5 hereof, for all acts of such subcontractor as if such acts
were its own. This Agreement shall be binding upon, and shall inure to the
benefit of, the parties hereto and their respective successors and permitted
assigns.

         ARTICLE 9. AMENDMENTS. This Agreement may be amended if such amendment
is specifically approved (i) by the vote of a majority of the Trustees of the
Trust, and (ii) by the vote of a majority of the Trustees of the Trust who are
not parties to this Agreement or interested persons of the Trust.

         ARTICLE 10. CERTAIN RECORDS. The Administrator shall maintain customary
records in connection with its duties as specified in this Agreement. Any
records required to be maintained and preserved pursuant to Rules 31a-1 and
31a-2 under the 1940 Act which are prepared or maintained by the Administrator
on behalf of the Trust shall be prepared and maintained at the expense of the
Administrator, but shall be the property of the Trust and will be made available
to or surrendered promptly to the Trust on request.

         In case of any request or demand for the inspection of such records by
another party, the Administrator shall notify the Trust and follow the Trust's
instructions as to permitting or refusing such inspection; provided that the
Administrator may exhibit such records to any person in any case where it is
advised by its counsel that it may be held liable for failure to do so, unless
(in cases involving potential exposure only to civil liability) the Trust has
agreed to indemnify the Administrator against such liability.

         ARTICLE 11. DEFINITIONS OF CERTAIN TERMS. The terms "interested person"
and "affiliated person," when used in this Agreement, shall have the respective
meanings specified in the 1940 Act and the rules and regulations thereunder,
subject to such exemptions as may be granted by the Securities and Exchange
Commission.

         ARTICLE 12. NOTICE. Any notice required or permitted to be given by
either party to the other shall be deemed sufficient if sent by registered or
certified mail, postage prepaid, addressed by the party giving notice to the
other party at the following address: if to the Administrator, to it at 3435
Stelzer Road, Columbus, Ohio 43219; if to the Trust, to it at Rosenberg

Edward H. Lyman, Esq., with a copy to J.B. Kittredge, Esq., Ropes & Gray, One
International Place, Boston, Massachusetts 02110-2624, or at such other address
as such party may from time to time specify in writing to the other party
pursuant to this Section.

         ARTICLE 13. GOVERNING LAW. This Agreement shall be construed in
accordance with the substantive laws of the State of Ohio and the applicable
provisions of the 1940 Act. To the extent that the applicable laws of the State
of Ohio, or any of the provisions herein, conflict with the applicable
provisions of the 1940 Act, the latter shall control.

         ARTICLE 14. MULTIPLE ORIGINALS. This Agreement may be executed in two
or more counterparts, each of which when so executed shall be deemed to be an
original, but such counterparts shall together constitute but one and the same
instrument.

         ARTICLE 15. CONFIDENTIAL INFORMATION. Each party acknowledges that it
may acquire knowledge and information relating to the other party and its
affiliates which is not generally known by others including, but not limited to,
information pertaining to business plans, prior, present or potential
shareholders, employees, customers and/or suppliers, and that all such knowledge
and information acquired or developed is and shall be confidential and
proprietary information (all such confidential and proprietary information is
herein collectively referred to as the "Confidential Information"). Each party
agrees to hold the Confidential Information in strict confidence, to refrain
from directly or indirectly disclosing it to others or using it in any way
except for purposes of performing services hereunder, and to prevent any
unauthorized person access to it either before or after termination of this
Agreement, without the prior written consent of the other party. Both parties
further agree to take all action reasonable and necessary to protect the
confidentiality of the Confidential Information. The parties shall use their
best efforts to have their officers, partners, employees and agents agree to the
terms of this Section. The obligations of the parties contained in this section
shall survive termination of this Agreement. Neither party's confidentiality
obligations under this provision shall apply to such information that (i) was in
the public domain or available to a third party without restrictions at or prior
to the time such information was made known to such party, (ii) had been
independently known to such party at the time of disclosure from persons who
were not subject to similar confidentiality obligations, or (iii) is required to
be disclosed by law (except that each party will use best efforts to give the
other party written notice prior to any such disclosure).

         ARTICLE 16. MATTERS RELATING TO THE TRUST AS A MASSACHUSETTS BUSINESS
TRUST. It is expressly agreed that the obligations of the Trust hereunder shall
not be binding upon any of the Trustees, shareholders, nominees, officers,
agents or employees of the Trust personally, but shall bind only the property of
the Trust. The execution and delivery of this Agreement have been authorized by
the Trustees, and this Agreement has been signed and delivered by an authorized
officer of the Trust, acting as such, and neither such authorization by the
Trustees nor such execution and delivery by such officer shall be deemed to have
been made by any of them individually or to impose any liability on any of them
personally, but shall bind only the property of the Trust as provided in the
Trust's Amended and Restated Agreement and Declaration of Trust, which is on
file with the Secretary of The Commonwealth of Massachusetts.

                         TO THE ADMINISTRATION AGREEMENT
                           DATED AS OF OCTOBER 1, 1998

                     BARR ROSENBERG VARIABLE INSURANCE TRUST

                         BISYS FUND SERVICES OHIO, INC.

Portfolios:       This Agreement shall apply to all Portfolios of
                  Barr Rosenberg Variable Insurance Trust, either or
                  hereafter created (collectively, the "Portfolios").
                  The current portfolios of the Trust are set forth
                  below:

                       Barr Rosenberg VIT Market Neutral Fund

Fees:             Pursuant to Article 4, in consideration of
                  services rendered and expenses assumed pursuant to
                  this Agreement, the Trust will pay the Administrator
                  on the first business day of each month, or at such
                  time(s) as the Administrator shall request and the
                  parties hereto shall agree, a fee computed daily at
                  the annual rate of:

                     Fifteen one-hundredths of one percent (0.15%) of the
                     Trust's average daily net assets

                  The fee for the period from the day of the month this
                  Agreement is entered into until the end of that month shall be
                  prorated according to the proportion which such period bears
                  to the full monthly period. Upon any termination of this
                  Agreement before the end of any month, the fee for such part
                  of a month shall be prorated according to the proportion which
                  such period bears to the full monthly period and shall be
                  payable upon the date of termination of this Agreement.

                  For purposes of determining the fees payable to the
                  Administrator, the value of the net assets of a particular
                  Portfolio shall be computed in the manner described in the
                  Trust's Amended and Restated Agreement and Declaration of
                  Trust or in the Prospectus or Statement of Additional
                  Information respecting that Portfolio as from time to time in
                  effect for the computation of the value of such net assets in
                  connection with the determination of the liquidating value of
                  the shares of such Portfolio.

                  The parties hereby confirm that the fees payable hereunder
                  shall be applied to each Portfolio as a whole, and not to
                  separate classes of shares within the Portfolios.


                                      A-1
<PAGE>

 Term:            The initial term of this Agreement (the "Initial
                  Term") shall be for a period commencing on the date
                  first written above and ending on October 1, 1999.
                  This Agreement shall be renewed automatically for
                  successive periods of  one year after the Initial
                  Term, unless written notice of nonrenewal is provided
                  by either  party not less than 60 days prior to the
                  end of the then-current term.  After the Initial
                  Term, (i) the Trust may terminate this Agreement at
                  any time, without the payment of any penalty, by a
                  vote of a majority of the Trust's outstanding voting
                  securities (as defined in the 1940 Act) or by a vote
                  of a majority of the Trustees of the Trust on 60
                  days' written notice to the Administrator and (ii) the
                  Administrator may terminate this Agreement at any
                  time, without penalty, on 60 days' written notice to
                  the Trust.  In the event of a material breach of this
                  Agreement by either party, the non-breaching party
                  shall notify the breaching party in writing of such
                  breach and upon receipt of such notice, the breaching
                  party shall have 45 days to remedy the breach.  In the
                  event the breach is not remedied within such time
                  period, the nonbreaching party may immediately
                  terminate this Agreement.

                  Notwithstanding the foregoing, after such termination for so
                  long as the Administrator, with the written consent of the
                  Trust, in fact continues to perform any one or more of the
                  services contemplated by this Agreement or any schedule or
                  exhibit hereto, the provisions of this Agreement, including
                  without limitation the provisions dealing with
                  indemnification, shall continue in full force and effect.
                  Compensation due the Administrator and unpaid by the Trust
                  upon such termination shall be immediately due and payable
                  upon and notwithstanding such termination. The Administrator
                  shall be entitled to collect from the Trust, in addition to
                  the compensation described in this Schedule A, the amount of
                  all of the Administrator's reasonable cash disbursements for
                  services in connection with the Administrator's activities in
                  effecting such termination, including without limitation, the
                  delivery to the Trust and/or its designees of the Trust's
                  property, records, instruments and documents, or any copies
                  thereof. Subsequent to such termination, for a reasonable fee,
                  the Administrator will provide the Trust with reasonable
                  access to any Trust documents or records remaining in its
                  possession.

                  If, for any reason other than a material breach of this
                  Agreement or termination of this Agreement by the Trust after
                  the Initial Term, the Administrator is replaced as fund
                  manager and administrator, or if a third party is added to
                  perform all or a part of the services provided by the
                  Administrator under this Agreement (excluding any
                  sub-administrator appointed by the Administrator as provided
                  in Article 8 hereof), then the Trust shall make a one-time
                  cash payment, as liquidated damages, to the Administrator
                  equal to the balance due the Administrator for the remainder
                  of the term of this Agreement, assuming for purposes of
                  calculation of the payment that the asset level of the Trust
                  on the date the Administrator is replaced, or a third party is
                  added, will remain constant for the balance of the contract
                  term.

                  In the event the Trust is merged into another legal entity in
                  part or in whole pursuant to any form of business organization
                  or is liquidated in part or in whole prior to the expiration
                  of the Initial Term of this Agreement, the parties acknowledge
                  and agree that (i) the liquidated damages provision set forth
                  above shall be applicable in those instances in which the
                  Administrator is not retained to provide administration
                  services and (ii) for purposes of calculating the payment
                  amount representing liquidated damages, the appropriate asset
                  level of the Trust shall be the greater of: (i) the asset
                  level calculated for the Trust at the time the Trust's Board
                  of Trustees receives notification of an intention on the part
                  of Fund management to effect such a business reorganization or
                  liquidation; (ii) the asset level calculated for the Trust at
                  the time the Trust's Board of Trustees formally approves such
                  a business reorganization or liquidation; or (iii) the asset
                  level calculated for the Trust on the day prior to the first
                  day during which assets are transferred by the Trust pursuant
                  to the plan of reorganization or liquidation. The one-time
                  cash payment referenced above shall be due and payable on the
                  day prior to the first day during which assets are transferred
                  pursuant to the plan of reorganization or liquidation.

                  The parties further acknowledge and agree that, in the event
                  the Administrator ceases to be retained, as set forth above,
                  (i) a determination of actual damages incurred by the
                  Administrator would be extremely difficult, and (ii) the
                  liquidated damages provision contained herein is intended to
                  adequately compensate the Administrator for damages incurred
                  and is not intended to constitute any form of penalty.

         5.       EFFECTIVE DATE.

                  This Agreement shall become effective with respect to a Fund
as of the date first written above.

         6.       TERM.

                  The initial term of this Agreement (the "Initial Term") shall
be for a period commencing on the date first written above and ending on October
1, 1999. This Agreement shall be renewed automatically for successive one-year
terms unless written notice not to renew is given by the non-renewing party to
the other party at least 60 days prior to the expiration of the then-current
term; provided, however, that, after the Initial Term, (i) the Trust may
terminate this Agreement at any time, without the payment of any penalty, by a
vote of a majority of the Trust's outstanding voting securities (as defined in
the 1940 Act) or by vote of a majority of the Trustees of the Trust on 60 days'
written notice to the Fund Accountant and (ii) the Fund Accountant may terminate
this Agreement at any time, without penalty, on 60 days' written notice to the
Trust; and, provided, further, that after this Agreement is terminated, for so
long as the Fund Accountant, with the written consent of the Trust, in fact
continues to perform any one or more of the services contemplated by this
Agreement or any schedule or exhibit hereto, the provisions of this Agreement,
including without limitation the provisions dealing with indemnification, shall
continue in full force and effect. Compensation due the Fund Accountant and
unpaid by the Trust upon such termination shall be immediately due and payable
upon and notwithstanding such termination. The Fund Accountant shall be entitled
to collect from the Trust, in addition to the compensation described under
Section 3 hereof, the amount of all of the Fund Accountant's reasonable cash
disbursements for services in connection with the Fund Accountant's activities
in effecting such termination, including without limitation, the delivery to the
Trust and/or its designees of the Trust's property, records, instruments and
documents, or any copies thereof. Subsequent to such termination, for a


                                      -5-
<PAGE>

reasonable fee, the Fund Accountant will provide the Trust with reasonable
access to any Trust documents or records remaining in its possession.

                  In the event of a material breach of this Agreement by either
party, the non-breaching party shall notify the breaching party in writing of
such breach and, upon receipt of such notice, the breaching party shall have 45
days to remedy the breach. In the event the breach is not remedied within such
time period, the nonbreaching party may immediately terminate this Agreement.

                  If, for any reason other than a material breach of this
Agreement or termination of this Agreement by the Trust after the Initial Term,
the Fund Accountant is replaced as the Fund Accountant, or if a third party is
added to perform all or a part of the services provided by the Fund Accountant
under this Agreement (excluding any sub-accountant appointed by the Fund
Accountant as provided in Section 2 hereof), then the Trust shall make a
one-time cash payment, as liquidated damages, to the Fund Accountant equal to
the balance due the Fund Accountant for the remainder of the term of this
Agreement, assuming for purposes of calculation of the payment that the asset
level of the Trust on the date the Fund Accountant is replaced, or a third party
is added, will remain constant for the balance of the contract term.

                  In the event the Trust is merged into another legal entity in
part or in whole or is otherwise liquidated in part or in whole pursuant to a
business reorganization prior to the expiration of the Initial Term of this
Agreement, the parties acknowledge and agree that (i) the liquidated damages
provision set forth above shall be applicable in those instances in which the
Fund Accountant is not retained to provide fund accounting services and (ii) for
purposes of calculating the payment amount representing liquidated damages, the
appropriate asset level of the Trust shall be the greater of: (i) the asset
level calculated for the Trust at the time the Trust's Board of Trustees
receives notification of an intention on the part of Fund management to effect
such a business reorganization or liquidation; (ii) the asset level calculated
for the Trust at the time the Trust's Board of Trustees formally approves such a
business reorganization or liquidation; or (iii) the asset level calculated for
the Trust on the day prior to the first day during which assets are transferred
by the Trust pursuant to the plan of reorganization or liquidation. The one-time
cash payment referenced above shall be due and payable on the day prior to the
first day during which assets are transferred to the surviving entity pursuant
to the plan of reorganization.

                  The parties further acknowledge and agree that, in the event
the Fund Accountant is replaced, or a third party is added as set forth above,
(i) a determination of actual damages incurred by the Fund Accountant would be
extremely difficult, and (ii) the liquidated damages provision contained herein
is intended to adequately compensate the Fund Accountant for damages incurred
and is not intended to constitute any form of penalty.

         7.       STANDARD OF CARE; RELIANCE ON RECORDS AND INSTRUCTIONS; 
                  INDEMNIFICATION.

                  The Fund Accountant shall use its best efforts to ensure the
accuracy of all services performed under this Agreement, but shall not be liable
to the Trust for any action taken or omitted 


                                      -6-
<PAGE>

by the Fund Accountant in the absence of bad faith, willful misfeasance,
negligence or reckless disregard by it of its obligations and duties. The Trust
agrees to indemnify and hold harmless the Fund Accountant, its employees,
agents, directors, officers and nominees from and against any and all claims,
demands, actions and suits, whether groundless or otherwise, and from and
against any and all judgments, liabilities, losses, damages, costs, charges,
reasonable counsel fees and other reasonable expenses of every nature and
character arising out of or in any way relating to the Fund Accountant's actions
taken or nonactions with respect to the performance of services under this
Agreement or based, if applicable, upon reasonable reliance on information,
records, instructions or requests with respect to a Fund given or made to the
Fund Accountant by a duly authorized representative of the Trust; provided that
this indemnification shall not apply to actions or omissions of the Fund
Accountant or its employees, agents, directors, officers or nominees in cases of
their own bad faith, willful misfeasance, negligence or reckless disregard by
any or all of them of the Fund Accountant's obligations and duties, and further
provided that prior to confessing any claim against it which may be the subject
of this indemnification, the Fund Accountant shall give the Trust written notice
of and reasonable opportunity to defend against said claim in its own name or in
the name of the Fund Accountant.

                  The Fund Accountant agrees to indemnify and hold harmless the
Trust, its employees, agents, Trustees, officers and nominees from and against
any and all actions, suits, demands and claims, whether groundless or otherwise,
and from and against any and all judgments, liabilities, losses, damages, costs,
charges, reasonable counsel fees and other expenses of every nature and
character arising out of or in any way relating to the Fund Accountant's or its
employees', agents', directors', officers' or nominees' bad faith, willful
misfeasance, negligence or reckless disregard by any or all of them of the Fund
Accountant's obligations and duties with respect to the performance of services
under this Agreement; provided, that, prior to confessing any claim against it
which may be the subject of this indemnification, the Trust shall give the Fund
Accountant written notice of and a reasonable opportunity to defend against said
claim in its own name or in the name of the Trust.

         The rights hereunder shall include the right to reasonable advances of
defense expenses in the event of any pending or threatened litigation with
respect to which indemnification hereunder may ultimately be merited. In order
that the indemnification provisions contained herein shall apply, however, it is
understood that if in any case the indemnifying party may be asked to indemnify
or hold the other party harmless, the indemnifying party shall be fully and
promptly advised of all pertinent facts concerning the situation in question,
and it is further understood that the indemnified party will use all reasonable
care to identify and notify the indemnifying party promptly concerning any
situation which presents or appears likely to present the probability of such a
claim for indemnification against the indemnifying party, but failure to do so
in good faith shall not affect the rights hereunder.

         The indemnifying party shall be entitled to participate at its own
expense or, if it so elects, to assume the defense of any suit brought to
enforce any claims subject to this indemnity provision. If the indemnifying
party elects to assume the defense of any such claim, the defense shall be


                                      -7-
<PAGE>

conducted by counsel chosen by the indemnifying party and satisfactory to the
other party, whose approval shall not be unreasonably withheld. In the event
that the indemnifying party elects to assume the defense of any suit and retain
counsel, the indemnified party shall bear the fees and expenses of any
additional counsel retained by it. If the indemnifying party does not elect to
assume the defense of a suit, it will reimburse the indemnified party for the
reasonable fees and expenses of any counsel retained by the other party.

         8.       RECORD RETENTION AND CONFIDENTIALITY.

                  The Fund Accountant shall keep and maintain on behalf of the
Trust all books and records which the Trust and the Fund Accountant is, or may
be, required to keep and maintain pursuant to any applicable statutes, rules and
regulations, including without limitation Rules 31a-1 and 31a-2 under the
Investment Company Act of 1940, as amended (the "1940 Act"), relating to the
maintenance of books and records in connection with the services to be provided
hereunder. The Fund Accountant further agrees that all such books and records
shall be the property of the Trust and to make such books and records available
for inspection by the Trust or by the SEC at reasonable times and otherwise to
keep confidential all books and records and other information relative to the
Trust and its shareholders; except when requested to divulge such information by
duly-constituted authorities or court process.

         9.       UNCONTROLLABLE EVENTS.

                  The Fund Accountant assumes no responsibility hereunder, and
shall not be liable, for any damage, loss of data, delay or any other loss
whatsoever caused by events beyond its reasonable control.

         10.      REPORTS.

                  The Fund Accountant will furnish to the Trust and to its
properly authorized auditors, investment advisers, examiners, distributors,

Fund Accountant's files, records and documents created and maintained by the
Fund Accountant pursuant to this Agreement which are no longer needed by the
Fund Accountant in the performance of its services or for its legal protection.

documents.

without restrictions at or prior to the time such information was made known to
such party, (ii) had been independently known to such party at the time of
disclosure from persons who were not subject to similar

confidentiality obligations, or (iii) is required to be disclosed by law (except
