P R O S P E C T U S                                           March 11, 1996
    
                           MENTOR INSTITUTIONAL TRUST
   
     Mentor Institutional Trust offers investors an opportunity to design an
investment program by investing in one or more different investment portfolios.
The Portfolios are being offered principally to institutional and high net-worth
individual investors.
    
   
     The MENTOR CASH MANAGEMENT PORTFOLIO is a "money market" fund, seeking as
high a rate of current income as Commonwealth Investment Counsel, Inc. believes
is consistent with preservation of capital and maintenance of liquidity. AN
INVESTMENT IN THAT PORTFOLIO IS NEITHER INSURED NOR GUARANTEED BY THE U.S.
GOVERNMENT. THERE CAN BE NO ASSURANCE THAT THE PORTFOLIO WILL BE ABLE TO
MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER SHARE.
    
   
     The MENTOR INTERMEDIATE DURATION PORTFOLIO and MENTOR FIXED-INCOME
PORTFOLIO seek a high level of long-term total return by investing in
diversified portfolios of investment-grade, fixed-income securities.
Preservation of capital is a secondary objective to the extent consistent with a
Portfolio's primary objective of seeking a high level of long-term total return.
MENTOR INTERMEDIATE DURATION PORTFOLIO will normally maintain a portfolio
duration of from two to five years. MENTOR FIXED-INCOME PORTFOLIO will normally
maintain a portfolio duration of from four to seven years. There is no limit on
the average weighted portfolio maturity these Portfolios may maintain, and a
Portfolio's average weighted maturity will likely be longer than its portfolio
duration. Commonwealth Investment Counsel, Inc. is the investment adviser for
these Portfolios.
    
   
     The MENTOR INTERNATIONAL PORTFOLIO seeks long-term capital appreciation by
investing in a diversified portfolio of equity securities of issuers outside the
United States. THIS PORTFOLIO MAY USE "LEVERAGE" -- THAT IS, IT MAY BORROW MONEY
TO PURCHASE ADDITIONAL PORTFOLIO SECURITIES, WHICH INVOLVES SPECIAL RISKS.
Mentor Perpetual Advisors, L.L.C. is the investment adviser to this Portfolio.
    
   
     This Prospectus sets forth concisely the information about the Portfolios
that a prospective investor should know before investing. Please read this
Prospectus and retain it for future reference. INVESTORS CAN FIND MORE DETAILED
INFORMATION IN THE MARCH 11, 1996 STATEMENT OF ADDITIONAL INFORMATION, AS
AMENDED FROM TIME TO TIME. FOR A FREE COPY OF THE STATEMENT, CALL MENTOR

EXPENSE SUMMARY
   
     Expenses are one of several factors to consider when investing in a
Portfolio. The following table summarizes an investor's maximum transaction
costs from investing in the Portfolios and, except for the International
Portfolio, expenses incurred for the past fiscal year. For the International
Portfolio, the expenses reflect those that the Portfolio expects to incur in its
first full fiscal year. The Examples show the cumulative expenses attributable
to a hypothetical $1,000 investment in each Portfolio over specified periods.

INVESTMENT OBJECTIVES AND POLICIES
MENTOR CASH MANAGEMENT PORTFOLIO.

   
THE MENTOR CASH MANAGEMENT PORTFOLIO'S INVESTMENT OBJECTIVE IS TO SEEK AS HIGH A
RATE OF CURRENT INCOME AS COMMONWEALTH INVESTMENT COUNSEL, INC. ("COMMONWEALTH")
BELIEVES IS CONSISTENT WITH PRESERVATION OF CAPITAL AND MAINTENANCE OF
LIQUIDITY. The Portfolio will invest in high-quality short-term instruments
including U.S. Government securities, banker's acceptances, prime commercial
paper, fixed-income securities of corporations and other private issuers, and
money market instruments. There can, of course, be no assurance that the
Portfolio will achieve its investment objective.
    

     The Portfolio will invest in a portfolio of high-quality short-term
instruments consisting of any or all of the following:

     (Bullet) U.S. GOVERNMENT SECURITIES: securities issued or guaranteed as to
              principal or interest by the U.S. Government or by any of its
              agencies or instrumentalities.

     (Bullet) BANKER'S ACCEPTANCES: negotiable drafts or bills of exchange,
              which have been "accepted" by a domestic bank (or a foreign bank
              with an agency domiciled in the United States), meaning, in
              effect, that the bank has unconditionally agreed to pay the face
              value of the instrument on maturity.

     (Bullet) PRIME COMMERCIAL PAPER: high-quality, short-term obligations
              issued by banks, corporations, and other issuers organized under
              the laws of a jurisdiction within the United States.

     (Bullet) OTHER SHORT-TERM OBLIGATIONS: high-quality, short-term obligations
              of corporate issuers.

     (Bullet) REPURCHASE AGREEMENTS: with respect to U.S. Government or agency
              securities.

   
     The Portfolio will invest only in U.S. dollar-denominated high-quality
securities and other U.S. dollar-denominated money market instruments meeting
credit criteria which the Trustees of the Trust believe present minimal credit
risk. "High-quality securities" are (i) commercial paper or other short-term
obligations rated A-1 by Standard & Poor's and P-1 by Moody's Investors Service,
Inc., and (ii) obligations rated AAA or AA by Standard & Poor's and Aaa or Aa by
Moody's at the time of investment. The Portfolio will not invest in securities
rated below A-1 or P-1 (or securities not so rated whose issuer does not have
outstanding short-term debt obligations, of comparable priority and security,
rated A-1 or P-1). The Portfolio will maintain a dollar-weighted average
maturity of 90 days or less and will not invest in securities with remaining
maturities of more than thirteen months. The Portfolio may invest in variable or
floating-rate securities which bear interest at rates subject to periodic
adjustment or which provide for periodic recovery of principal on demand. Under
certain conditions, these securities may be deemed to have remaining maturities
equal to the time remaining until the next interest adjustment date or the date
on which principal can be recovered on demand. The Portfolio will not purchase
securities of any issuer if, immediately thereafter, more than 5% of its total
assets would be invested in securities of that issuer, nor will the Portfolio
make an investment in commercial paper if, immediately thereafter, more than 35%
of its total assets would be invested in commercial paper. The Portfolio follows
investment and valuation policies designed to maintain a stable net asset value
of $1.00 per share, although there is no assurance that these policies will be
successful.
    

     Considerations of liquidity and preservation of capital mean that the
Portfolio may not necessarily invest in money market instruments paying the
highest available yield at a particular time. Consistent with its investment
objective, the Portfolio will attempt to maximize yields by portfolio trading
and by buying and selling portfolio investments in anticipation of or in
response to changing economic and money market conditions and trends. The
Portfolio may also invest to take advantage of what Commonwealth believes to be
temporary disparities in yields

                                       4

<PAGE>


of different segments of the high-quality money market or among particular
instruments within the same segment of the market. These policies, as well as
the relatively short maturity of obligations purchased by the Portfolio, may
result in frequent changes in the securities held by the Portfolio. The
Portfolio will not usually pay brokerage commissions in connection with the
purchase or sale of portfolio securities.

     The Portfolio's securities will be affected by general changes in interest
rates resulting in increases or decreases in the values of the obligations held
by the Portfolio. The value of the Portfolio's securities can be expected to
vary inversely to changes in prevailing interest rates. Withdrawals by
shareholders could require the sale of portfolio investments at a time when such
a sale might not otherwise be desirable.

   
     CONCENTRATION. The Portfolio may invest without limit in obligations of
domestic branches of U.S. banks and U.S. branches of foreign banks (if it can be
demonstrated that they are subject to the same regulations as U.S. banks). At
times when the Portfolio has concentrated its investments in bank obligations,
the value of its portfolio securities may be especially affected by factors
pertaining to the issuers of such obligations.
    

MENTOR INTERMEDIATE DURATION PORTFOLIO AND MENTOR FIXED-INCOME PORTFOLIO.

     The investment objective of both of these Portfolios is to seek a high
level of long-term total return. Preservation of capital is a secondary
objective to the extent consistent with a Portfolio's primary objective of
seeking a high level of long-term total return. The Portfolios will invest in
U.S. Government securities, fixed-income securities of corporations and other
private issuers, mortgage-backed securities, and other asset-backed securities.
Each of the Portfolios may also hold a portion of its assets in cash or money
market instruments. There can, of course, be no assurance that the Portfolios
will achieve their investment objectives.

    The INTERMEDIATE DURATION PORTFOLIO will normally maintain a portfolio
duration of from TWO TO FIVE YEARS.

     The FIXED-INCOME PORTFOLIO will normally maintain a portfolio duration of
from FOUR TO SEVEN YEARS.

     A Portfolio's "portfolio duration" at any time is the dollar-weighted
average duration of its portfolio securities at that time. In general, the net
asset value of a Portfolio with a longer portfolio duration will increase or
decrease to a greater degree in response to changes in interest rates than will
the net asset value of a Portfolio with a shorter portfolio duration.
(Typically, for example, the value of a security with a three-year duration will
increase by approximately three percent in response to a one-percent decline in
interest rates, and will decline by approximately three percent in response to a
one-percent rise in interest rates; similarly, the value of a security with a
seven-year duration will increase by approximately seven percent in response to
a one-percent decline in interest rates, and will decline by approximately seven
percent in response to a one-percent rise in interest rates; and so on.)
However, because issuers of securities with longer durations typically pay
interest on those securities at rates higher than in the case of securities with
shorter durations, the current income of a Portfolio with a longer portfolio
duration will typically be greater than that of a Portfolio with a shorter
portfolio duration.

     Commonwealth may take full advantage of the entire range of maturities of
the securities in which a Portfolio may invest and may, through the purchase and
sale of securities with different durations, adjust each Portfolio's portfolio
duration from time to time, depending on its assessment of the relative values
of securities of different durations and maturities and expectations of future
changes in interest rates. There can be no assurance that either Portfolio will
be able to maintain any particular portfolio duration.

     A Portfolio's "total return" consists of current income, including interest
payments and discount accruals, plus any increases in the values of the
Portfolio's investments (less any decreases in the values of any of its
investments and amortizations of premiums). A Portfolio may seek to increase its
total return by investing in

                                       5

<PAGE>

investment-grade securities which Commonwealth believes may appreciate in value
as a result of changes in interest rates or other market factors.

     Traditionally, a debt security's "term to maturity" has been used to
evaluate the sensitivity of the security's price to changes in interest rates
(the security's interest-rate "volatility"). However, a security's term to
maturity measures only the period of time until the last payment of principal or
interest on the security, and does not take into account the timing of the
various payments of principal or interest to be made prior to the instrument's
maturity. By contrast, "duration" is a measure of the full stream of payments to
be received on a debt instrument, including both interest and principal
payments, based on their present values. Duration measures the periods of time
between the present time and the time when the various interest and principal
payments are scheduled or, in the case of a callable bond, expected to be
received, and weights them by their present values. Duration can be a more
accurate measure of interest rate volatility than term-to-maturity. There is no
limit on the average weighted maturity either Portfolio may maintain, and a
Portfolio's average weighted maturity will likely be longer than its portfolio
duration.
   
     There are some situations where the standard duration calculation does not
properly reflect the interest-rate volatility of a security. For example,
floating and variable rate securities often have final maturities of ten years
or more; however, their interest-rate volatility is determined based principally
on the period of time until their interest rates are reset and on the terms on
which they may be reset. Another example where a security's interest-rate
volatility is not properly measured by the standard duration calculation is in
the case of mortgage-backed securities. The stated final maturity of such
securities may be up to 30 years, but the actual cash flow on the securities
will be determined by the prepayment rates on the underlying mortgage loans.
Therefore, the duration of such a security can change if prepayment rates
change. In these and other similar situations, Commonwealth will estimate a
security's duration using analytical techniques that take into account such
factors as the expected prepayment rate on the security and how the prepayment
rate might change under various market conditions. Because calculation of a
security's duration may be based in part on estimates such as these made by
Commonwealth, a Portfolio's ability to maintain a particular portfolio duration
will depend on Commonwealth's ability to make those estimates accurately.
    
     The Fixed-Income Portfolio will normally invest at least 65% of its total
assets, determined at the time of investment, in fixed-income securities. A
fixed-income security is a debt security paying interest at a rate specified in
the terms of the security or determined based on a formula or factors specified
in the terms of the security.

     The Portfolios will only invest in securities of investment grade. A
security will be deemed to be of "investment grade" if, at the time of
investment by a Portfolio, the security is rated at least Baa3 by Moody's or
BBB-by Standard & Poor's, or at a comparable rating by another nationally
recognized rating organization. Securities rated Baa or BBB lack outstanding
investment characteristics and have speculative characteristics and are subject
to greater credit and market risks than higher-rated securities. A Portfolio
will not be required to dispose of a security held by it if the security's
rating falls below investment grade, although Commonwealth will consider whether
continued investment in the security is consistent with the Portfolio's
investment objectives. See the Statement of Additional Information for
descriptions of securities ratings assigned by Moody's and Standard & Poor's.

     Commonwealth may under unusual circumstances implement temporary
"defensive" strategies in order to reduce fluctuations in the value of a
Portfolio's assets. At those times, a Portfolio may invest any portion of its
assets in cash or cash equivalents, money market instruments, or other
short-term, high-quality investments Commonwealth considers consistent with such
defensive strategies, and may maintain a portfolio duration shorter than would
otherwise be consistent with its basic investment strategy.

MENTOR INTERNATIONAL PORTFOLIO.

     THE INTERNATIONAL PORTFOLIO'S INVESTMENT OBJECTIVE IS LONG-TERM CAPITAL
APPRECIATION. The Portfolio is designed for institutional investors who believe
that investment in a diversified portfolio of securities of issuers located
outside the U.S. offers the potential for long-term capital appreciation.

   
     The Portfolio invests in a diversified portfolio of securities of issuers
located outside the United States. The Portfolio's investments will normally
include common stocks, preferred stocks, securities convertible into common
stocks or preferred stocks, and warrants to purchase common stocks or preferred
stocks. The Portfolio may also invest to a lesser extent in debt securities and
other types of investments if Mentor Perpetual Advisors, L.L.C. ("Mentor
Perpetual") believes they would help achieve the Portfolio's objective. The
Portfolio may hold a portion of its assets in cash or money market instruments.
    

     The Portfolio will not limit its investments to any particular type of
company. The Portfolio may invest in companies, large or small, whose earnings
are believed to be in a relatively strong growth trend, or in companies in which
significant further growth is not anticipated but whose market value per share
is thought to be undervalued.

     It is likely that, at times, a substantial portion of the Portfolio's
assets will be invested in securities of issuers in emerging markets, including
under-developed and developing nations. Investments in emerging markets are
subject to the same risks applicable to foreign investments generally, although
those risks may be increased due to conditions in such markets. For example, the
securities markets and legal systems in emerging markets may only be in a
developmental stage and may provide few, or none, of the advantages or
protections of markets or legal systems available in more developed countries.
Although many of the securities in which the Portfolio may invest are traded on
securities exchanges, they may trade in limited volume, and the exchanges may
not provide all of the conveniences or protections provided by securities
exchanges in more developed markets. The Portfolio may also invest a substantial
portion of its assets in securities traded in the over-the-counter markets and
not on any exchange, which may affect the liquidity of the investment and expose
the Portfolio to the credit risk of its counterparties in trading those
investments. See "Other investment practices -- Foreign securities."

   
     Fixed-income securities in which the Portfolio may invest will be of
investment grade. A security will be deemed to be of "investment grade" if, at
the time of investment by the Portfolio, the security is rated at least Baa3 by
Moody's or BBB- by Standard & Poor's, or at a comparable rating by another
nationally recognized rating organization. Securities rated Baa or BBB lack
outstanding investment characteristics and have speculative characteristics and
are subject to greater credit and market risks than higher-rated securities. The
Portfolio will not be required to dispose of a security held by it if the
security's rating falls below investment grade, although Mentor Perpetual will
consider whether continued investment in the security is consistent with the
Portfolio's investment objective. See the Statement of Additional Information
for descriptions of securities ratings assigned by Moody's and Standard &
Poor's.
    

     Mentor Perpetual may under unusual circumstances implement temporary
"defensive" strategies in order to reduce fluctuations in the value of the
Portfolio's assets. At those times, the Portfolio may invest any portion of its
assets in cash or cash equivalents, money market instruments, or other
short-term, high-quality investments Mentor Perpetual considers consistent with
such defensive strategies.

     The International Portfolio may invest a substantial portion of its assets
in securities issued by small companies. Such companies may offer greater
opportunities for capital appreciation than larger companies, but investments in
such companies may involve certain special risks. Such companies may have
limited product lines, markets, or financial resources and may be dependent on a
limited management group. While the markets in

                                       7

<PAGE>


securities of such companies have grown rapidly in recent years, such securities
may trade less frequently and in smaller volume than more widely held
securities. The values of these securities may fluctuate more sharply than those
of other securities, and the Portfolio may experience some difficulty in
establishing or closing out positions in these securities at prevailing market
prices. There may be less publicly-available information about the issuers of
these securities or less market interest in such securities than in the case of
larger companies, and it may take a longer period of time for the prices of such
securities to reflect the full value of their issuers' underlying earnings
potential or assets.

     Some securities of smaller issuers may be restricted as to resale or may
otherwise be highly illiquid. The ability of the Portfolio to dispose of such
securities may be greatly limited, and the Portfolio may have to continue to
hold such securities during periods when Mentor Perpetual would otherwise have
sold the security. It is possible that Mentor Perpetual or its affiliates or
clients may hold securities issued by the same issuers, and may in some cases
have acquired the securities at different times, on more favorable terms, or at
more favorable prices, than the Portfolio.
   
     FOREIGN SECURITIES. Investment in foreign securities entails certain risks.
Since foreign securities are normally denominated and traded in foreign
currencies, the values of the Portfolio's assets may be affected favorably or
unfavorably by currency exchange rates and exchange control regulations. There
may be less information publicly available about a foreign company than about a
U.S. company, and foreign companies are not generally subject to accounting,
auditing, and financial reporting standards and practices comparable to those in
the United States. The securities of some foreign companies are less liquid and
at times more volatile than securities of comparable U.S. companies. Foreign
brokerage commissions and other fees are also generally higher than in the
United States. Foreign settlement procedures and trade regulations may involve
certain risks (such as delay in payment or delivery of securities or in the
recovery of the Portfolio's assets held abroad) and expenses not present in the
settlement of domestic investments.
    

     In addition, there may be a possibility of nationalization or expropriation
of assets, imposition of currency exchange controls, confiscatory taxation,
political or financial instability, and diplomatic developments which could
affect the value of the Portfolio's investments in certain foreign countries.
Legal remedies available to investors in certain foreign countries may be more
limited than those available with respect to investments in the United States or
in other foreign countries. In the case of securities issued by a foreign
governmental entity, the issuer may in certain circumstances be unable or
unwilling to meet its obligations on the securities in accordance with their
terms, and the Portfolio may have limited recourse available to it in the event
of default. The laws of some foreign countries may limit the Portfolio's ability
to invest in securities of certain issuers located in those foreign countries.
Special tax considerations apply to foreign securities. The Portfolio may buy or
sell foreign currencies and options and futures contracts on foreign currencies
for hedging purposes in connection with its foreign investments.

OTHER INVESTMENT PRACTICES AND RISKS

     Each of the Portfolios (except as noted below) may engage in the other
investment practices described below. See the Statement of Additional
Information for a more detailed description of these practices and certain risks
they may involve.

     MORTGAGE-BACKED SECURITIES. The Intermediate Duration and Fixed-Income
Portfolios may invest in mortgage-backed certificates and other securities
representing ownership interests in mortgage pools, including collateralized
mortgage obligations. Interest and principal payments on the mortgages
underlying mortgage-backed

                                       8

<PAGE>


securities are passed through to the holders of the mortgage-backed securities.
Mortgage-backed securities currently offer yields higher than those available
from many other types of fixed-income securities, but because of their
prepayment aspects, their price volatility and yield characteristics will change
based on changes in prepayment rates. Generally, prepayment rates increase if
interest rates fall and decrease if interest rates rise. For many types of
mortgage-backed securities, this can result in unfavorable changes in price and
yield characteristics in response to changes in interest rates and other market
conditions. For example, as a result of their prepayment aspects, the
Portfolios' mortgage-backed securities have less potential for capital
appreciation during periods of declining interest rates than other fixed-income
securities of comparable maturities, although such obligations may have a
comparable or greater risk of decline in market value during periods of rising
interest rates.

     Mortgage-backed securities have yield and maturity characteristics that are
dependent on the mortgages underlying them. Thus, unlike traditional debt
securities, which may pay a fixed rate of interest until maturity when the
entire principal amount comes due, payments on these securities include both
interest and a partial payment of principal. In addition to scheduled loan
amortization, payments of principal may result from the voluntary prepayment,
refinancing, or foreclosure of the underlying mortgage loans. Such prepayments
may significantly shorten the effective durations of mortgage-backed securities,
especially during periods of declining interest rates. Similarly, during periods
of rising interest rates, a reduction in the rate of prepayments may
significantly lengthen the effective durations of such securities.

     OTHER ASSET-BACKED SECURITIES. The Intermediate Duration and Fixed-Income
Portfolios may invest in securities representing interests in other types of
financial assets, such as automobile-finance receivables or credit-card
receivables. Such securities are subject to many of the same risks as are
mortgage-backed securities, including prepayment risks, refinancing risks, and
risks of foreclosure. They may or may not be secured by the receivables
themselves or may be unsecured obligations of their issuers.

     WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS. The Intermediate Duration
and Fixed-Income Portfolios may purchase securities on a "when-issued" basis.
The price of such securities is fixed at the time the commitment to purchase is
made, but delivery and payment for the when-issued securities take place at a
later date (normally within one month of purchase). Each of these Portfolios may
also purchase securities for future delivery. "When-issued" securities and
forward commitments may increase a Portfolio's overall investment exposure and
may result in losses.
   
     REPURCHASE AGREEMENTS; SECURITIES LOANS. The Portfolios may enter into
repurchase agreements and (in the case of the International Portfolio)
securities loans. Under a repurchase agreement, a Portfolio purchases a debt
instrument for a relatively short period (usually not more than one week), which
the seller agrees to repurchase at a fixed time and price, representing the
Portfolio's cost plus interest. Under a securities loan, a Portfolio lends
portfolio securities. A Portfolio will enter into repurchase agreements and (in
the case of the International Portfolio) securities loans only with commercial
banks and with registered broker-dealers who are members of a national
securities exchange or market makers in government securities, and in the case
of repurchase agreements, only if the debt instrument is a U.S. Government
security. Although Commonwealth or Mentor Perpetual, as the case may be, will
monitor these transactions to ensure that they will be fully collateralized at
all times, a Portfolio bears a risk of loss if the other party defaults on its
obligation and the Portfolio is delayed or prevented from exercising its rights
to dispose of the collateral. If the other party should become involved in
bankruptcy or insolvency proceedings, it is possible that the Portfolio may be
treated as an unsecured creditor and be required to return the underlying
collateral to the other party's estate.
    

     BORROWING AND LEVERAGE. The International Portfolio may borrow money to
invest in additional portfolio securities. This practice, known as "leverage",
increases the Portfolio's market exposure and its risk. When the

                                       9

<PAGE>


Portfolio has borrowed money for leverage and its investments increase or
decrease in value, the Portfolio's net asset value will normally increase or
decrease more than if it had not borrowed money. The interest the Portfolio must
pay on borrowed money will reduce the amount of any potential gains or increase
any losses. The extent to which the Portfolio will borrow money, and the amount
it may borrow, depend on market conditions and interest rates. Successful use of
leverage depends on Mentor Perpetual's ability to predict market movements
correctly.

   
     OPTIONS AND FUTURES. Each of the Portfolios (other than the Cash Management
Portfolio) may buy and sell call and put options to hedge against changes in net
asset value or to realize a greater current return. In addition, through the
purchase and sale of futures contracts and related options, these Portfolios may
at times seek to hedge against fluctuations in net asset value and, to the
extent consistent with applicable law, to increase investment return.
    

   
     A Portfolio's ability to engage in options and futures strategies will
depend on the availability of liquid markets in such instruments. It is
impossible to predict the amount of trading interest that may exist in various
types of options or futures contracts. Therefore, there is no assurance that a
Portfolio will be able to utilize these instruments effectively for the purposes
stated above. Transactions in options and futures involve certain risks which
are described below and in the Statement of Additional Information.
    

   
     Transactions in options and futures contracts involve brokerage costs and
may require a Portfolio to segregate assets to cover its outstanding positions.
For more information, see the Statement of Additional Information.
    

   
     INDEX FUTURES AND OPTIONS. The Portfolios (other than the Cash Management
Portfolio) may buy and sell index futures contracts ("index futures") and
options on index futures and on indices for hedging purposes (or may purchase
warrants whose value is based on the value from time to time of one or more
foreign securities indices). An "index future" is a contract to buy or sell
units of a particular bond or stock index at an agreed price on a specified
future date. Depending on the change in value of the index between the time when
a Portfolio enters into and terminates an index futures or option transaction,
the Portfolio realizes a gain or loss. The Portfolios (other than the Cash
Management Portfolio) may also, to the extent consistent with applicable law,
buy and sell index futures and options to increase its investment return.
    

   
     RISKS RELATED TO OPTIONS AND FUTURES STRATEGIES. OPTIONS AND FUTURES
TRANSACTIONS INVOLVE COSTS AND MAY RESULT IN LOSSES. Certain risks arise because
of the possibility of imperfect correlations between movements in the prices of
futures and options and movements in the prices of the underlying security or
index or of the securities held by a Portfolio that are the subject of a hedge.
The successful use by a Portfolio of the strategies described above further
depends on the ability of its investment adviser to forecast market movements
correctly. Other risks arise from a Portfolio's potential inability to close out
futures or options positions. Although a Portfolio will enter into options or
futures transactions only if its investment adviser believes that a liquid
secondary market exists for such options or futures contracts, there can be no
assurance that the Portfolio will be able to effect closing transactions at any
particular time or at an acceptable price. Certain provisions of the Internal
Revenue Code may limit a Portfolio's ability to engage in options and futures
transactions.
    

   
     Each Portfolio generally expects that its options transactions
will be conducted on recognized exchanges. A Portfolio may in certain instances
purchase and sell options in the over-the-counter markets. A Portfolio's ability
to terminate options in the over-the-counter markets may be more limited than
for exchange-traded options and may also involve the risk that securities
dealers participating in such transactions would be unable to meet their
obligations to the Portfolio. A Portfolio will, however, engage in
over-the-counter transactions only when appropriate exchange-traded transactions
are unavailable and when, in the opinion of its investment adviser, the pricing
mechanism and liquidity of the over-the-counter markets are satisfactory and the
participants are responsible parties likely to meet their obligations.
    

                                       10

<PAGE>

   
     A Portfolio will not purchase futures or options on futures or sell futures
if as a result the sum of the initial margin deposits on the Portfolio's
existing futures positions and premiums paid for outstanding options on futures
contracts would exceed 5% of the Portfolio's assets. (For options that are
"in-the-money" at the time of purchase, the amount by which the option is
"in-the-money" is excluded from this calculation.)
    

   
     As a matter of policy, the Trustees will not materially change a
Portfolio's investment objective without shareholder approval. (Any such change
could, of course, result in a change in the nature of the securities in which a
Portfolio may invest and the risks involved in an investment in that Portfolio.)
    

MANAGEMENT

     The Trustees of the Trust are responsible for generally overseeing the
conduct of the Trust's business. COMMONWEALTH INVESTMENT COUNSEL, INC., located
at 901 East Byrd Street, Richmond, Virginia 23219, acts as investment adviser to
the Cash Management, Fixed-Income, and Intermediate Duration Portfolios pursuant
to a Management Contract with the Trust. MENTOR PERPETUAL ADVISORS, L.L.C.,
located at 901 East Byrd Street, Richmond, Virginia, acts as investment adviser
to the International Portfolio pursuant to a Management Contract with the Trust.
Mentor Investment Group, Inc. ("Mentor") serves as administrator to the
Portfolios. None of Commonwealth, Mentor Perpetual, or Mentor receives
compensation from the Portfolios for the performance of such services. Mentor
has agreed to bear certain expenses of the Portfolios pursuant to a voluntary
expense limitation currently in effect. This limitation may be terminated at any
time.

   
     Commonwealth is a wholly owned subsidiary of Mentor, which is a wholly
owned subsidiary of Wheat First Butcher Singer, Inc. ("Wheat First Butcher
Singer"). Wheat First Butcher Singer, through other subsidiaries, also engages
in securities brokerage, investment banking, and related businesses.
Commonwealth currently has assets under management of approximately $4 billion,
and serves as investment adviser to Cash Resource Trust, an open-end series
investment company, the Mentor Balanced Portfolio, the Mentor Short-Duration
Income Portfolio, SNAP Fund, and America's Utility Fund, Inc., each of which is
an open-end investment company, and Mentor Income Fund, Inc., a closed-end
investment company. All investment decisions for the Cash Management,
Fixed-Income, and Intermediate Duration Portfolios are made by investment
committees at Commonwealth which are made up of investment professionals at
Commonwealth.
    

     Mentor Perpetual is a newly organized investment advisory firm owned
equally by Perpetual plc and Mentor. The Perpetual organization currently serves
as investment adviser for assets of more than $6 billion. It clients include 28
unit investment trusts and other public investment pools for over 150 clients,
including private individuals, charities, pension plans, and life assurance
companies. Mentor Perpetual currently serves as investment adviser to the Mentor
Perpetual Global Portfolio, an open-end mutual fund which is a series of The
Mentor Funds. Investment decisions for the Portfolio are made by a team of
investment professionals at Mentor Perpetual. Mentor is a wholly owned
subsidiary of Wheat First Butcher Singer.

   

     Subject to the general oversight of the Trustees, Commonwealth and Mentor
Perpetual manage their respective Portfolios in accordance with the stated
policies of each such Portfolio. Each of Commonwealth and Mentor Perpetual makes
investment decisions for its respective Portfolios and places the purchase and
sale orders for each Portfolio's portfolio transactions. In selecting
broker-dealers, Commonwealth and Mentor Perpetual may consider research and
brokerage services furnished to them and their affiliates. Subject to seeking
the best overall terms available, Commonwealth and Mentor Perpetual may consider
sales of shares of a Portfolio (and, if permitted by law, of other funds in the
Mentor family) as a factor in the selection of broker-dealers to execute
portfolio transactions for that Portfolio. Commonwealth and Mentor Perpetual may
at times cause the Portfolios to pay commissions to broker-

    

                                       11

<PAGE>

   
dealers which are affiliated with Commonwealth or Mentor Perpetual.
    

   
     PORTFOLIO TURNOVER (ALL PORTFOLIOS OTHER THAN THE CASH MANAGEMENT
PORTFOLIO). The length of time a Portfolio has held a particular security is not
generally a consideration in investment decisions. A change in the securities
held by a Portfolio is known as "portfolio turnover." As a result of each
Portfolio's investment policies, under certain market conditions a Portfolio's
portfolio turnover rate may be higher than that of other mutual funds. Portfolio
turnover generally involves some expense to a Portfolio, including brokerage
commissions or dealer mark-ups and other transaction costs on the sale of
securities and reinvestment in other securities. Such transactions may result in
realization of taxable capital gains. Although it is impossible to predict
portfolio turnover, Mentor Perpetual expects that the annual portfolio turnover
rate for the International Portfolio for its first full fiscal year will not
exceed 200%. The portfolio turnover rate for the Fixed-Income and Intermediate
Duration Portfolios for the 1995 fiscal period is shown in the section
"Financial Highlights."
    

HOW THE PORTFOLIOS VALUE THEIR SHARES

     Each of the Portfolios (other than the Cash Management Portfolio)
calculates the net asset value of its shares by dividing the total value of its
assets, less liabilities, by the number of its shares outstanding. Shares are
valued as of the close of regular trading on the New York Stock Exchange each
day the Exchange is open. Portfolio securities for which market quotations are
readily available are stated at market value. Short-term investments that will
mature in 60 days or less are stated at amortized cost, which has been
determined to approximate the fair market value of such investments. All other
securities and assets are valued at their fair values.

     The CASH MANAGEMENT PORTFOLIO values its shares twice each day, once at
12:00 noon and again at the close of regular trading on the Exchange. The
Portfolio's investments are valued at amortized cost according to Securities and
Exchange Commission Rule 2a-7. The Portfolio will not normally have unrealized
gains or losses so long as it values its investments by the amortized cost
method.

HOW DISTRIBUTIONS ARE MADE

     The FIXED-INCOME and INTERMEDIATE DURATION PORTFOLIOS distribute net
investment income quarterly and any net realized capital gains at least
annually. The INTERNATIONAL PORTFOLIO distributes net investment income and any
net realized capital gains at least annually. Distributions from capital gains
are made after applying any available capital loss carryovers.

     The CASH MANAGEMENT PORTFOLIO determines its net income as of the close of
regular trading on the New York Stock Exchange each day the Exchange is open.
Each determination of the Portfolio's net income includes (i) all accrued
interest on the Portfolio's investments, (ii) plus or minus all realized and
unrealized gains and losses on the Portfolio's investments, (iii) less all
accrued expenses of the Portfolio.

     The Cash Management Portfolio declares all of its net interest income as a
distribution on each day the New York Stock Exchange is open for business, as a
dividend to shareholders of record immediately prior to the close of regular
trading on the Exchange. Shareholders who purchase shares of the Portfolio as of
12:00 noon on any day will receive the dividend declared by the Portfolio for
that day; shareholders who purchase shares after 12:00 noon will begin earning
dividends on the day after the Portfolio accepts their order. The Portfolio's
net income for Saturdays, Sundays, and holidays is declared as a dividend on the
preceding business day. Dividends for the immediately preceding month will be
paid on the last business day of each calendar month (or, if that day is not a
business day, on the next business day), except that the Portfolio's schedule
for payment of dividends during the month of December may be adjusted to assist
in tax reporting and distribution requirements. A shareholder that

                                       12

<PAGE>


withdraws the entire balance of an account at any time during the month will be
paid all dividends declared through the date immediately prior to the
withdrawal. Since the net income of the Portfolio is declared as a dividend each
day, the net asset value per share of the Portfolio normally remains at $1 per
share immediately after each determination and dividend declaration.

     All Portfolio distributions will be invested in additional Portfolio
shares, unless the shareholder instructs a Portfolio otherwise.

TAXES

     Each of the Portfolios intends to qualify as a "regulated investment
company" for federal income tax purposes and to meet all other requirements that
are necessary for it to be relieved of federal taxes on income and gains it
distributes to shareholders. The Portfolios will distribute substantially all of
their net investment income and capital gain net income on a current basis.

  THE FOLLOWING IS INTENDED PRINCIPALLY FOR SHAREHOLDERS SUBJECT TO FEDERAL
INCOME TAXATION:

   
     All Portfolio distributions, other than exempt-interest dividends, will be
taxable to shareholders as ordinary income, except that any distributions of net
capital gain will be taxed as long-term capital gain, regardless of how long a
shareholder has held the shares (although the loss on a sale of shares held for
six months or less will be treated as long-term capital loss to the extent of
any capital gain distribution received with respect to those shares).
Distributions will be taxable as described above whether received in cash or in
shares through the reinvestment of distributions. Early in each year the Trust
will notify shareholders of the amount and tax status of distributions paid by a
Portfolio for the preceding year. In buying or selling securities for a
Portfolio, an investment adviser will not normally take into account the effect
any purchase or sale of securities will have on the tax positions of the
Portfolio's shareholders.
    

     The foregoing is a summary of certain federal income tax consequences of
investing in a Portfolio. Dividends and distributions also may be subject to
state and local taxes. Shareholders are urged to consult their tax advisers
regarding specific questions as to federal, state, or local taxes. Non-U.S.
investors should consult their tax advisers concerning the tax consequences of
ownership of shares of a Portfolio, including the possibility that distributions
may be subject to a 30% United States withholding tax (or a reduced rate of
withholding provided by treaty).

PURCHASE OF SHARES

     Shares of the FIXED-INCOME, INTERMEDIATE DURATION, and INTERNATIONAL
PORTFOLIOS are sold at the net asset value next determined after a purchase
order is received by a Portfolio. Purchase orders that are received prior to the
close of trading on the New York Stock Exchange on a particular day are priced
according to the net asset value determined on that day.

     The CASH MANAGEMENT PORTFOLIO offers its shares continuously at a price of
$1.00 per share. Because the Portfolio seeks to be fully invested at all times,
investments must be in Same Day Funds to be accepted. "Same Day Funds" are funds
credited by the applicable regional Federal Reserve Bank to the account of the
Portfolio at its designated bank.

                                       13

<PAGE>


     Mentor Distributors, Inc. ("Mentor Distributors"), 901 East Byrd Street,
Richmond, Virginia 23219, serves as distributor of the Portfolios' shares.
Mentor Distributors is not obligated to sell any specific amount of shares of
any of the Portfolios.

   
     An investor may make an initial purchase of shares of any of the Portfolios
by submitting a completed application along with its purchase order, and by
making payment to Mentor Distributors. Investors will be required to make
minimum initial investments of $500,000 in the Portfolios and minimum subsequent
investments of $25,000. Investments made through advisory accounts maintained
with investment advisers registered under the Investment Advisers Act of 1940
(including "wrap" accounts) are not subject to these minimum investment
requirements. The Portfolios reserve the right at any time to change the initial
and subsequent investment minimums required of investors.
    

   
     Shares of the Portfolios may be purchased by (i) paying cash, (ii)
exchanging securities acceptable to a Portfolio's investment adviser, or (iii) a
combination of such securities and cash. Purchase of shares of a Portfolio in
exchange for securities is subject in each case to the determination by the
Portfolio's investment adviser that the securities to be exchanged are
acceptable for purchase by the Portfolio. Securities accepted by a Portfolio's
investment adviser in exchange for shares will be valued in the same manner as
the Portfolio's assets as of the time of the Portfolio's next determination of
net asset value after such acceptance. All dividends and subscription or other
rights which are reflected in the market price of accepted securities at the
time of valuation become the property of the Portfolio and must be delivered to
the Portfolio upon receipt by the investor from the issuer. A gain or loss for
federal income tax purposes would be realized upon the exchange by an investor
that is subject to federal income taxation, depending upon the investor's basis
in the securities tendered. A shareholder who wishes to purchase shares by
exchanging securities should obtain instructions by calling Mentor Distributors
at 1-800-869-6042.
    

     In all cases Commonwealth, Mentor Perpetual, or Mentor Distributors
reserves the right to reject any investment.

REDEMPTION OF SHARES

     A shareholder may redeem all or any portion of its shares in a Portfolio at
any time upon request, by following the procedures set forth below. Redemptions
will be effected at the net asset value per share of a Portfolio next determined
after the receipt by the Portfolio of redemption instructions in "good order" as
described below. Shares may be redeemed by submitting a written request for
redemption to Mentor Distributors, or to the Trust at the following address:

                           Mentor Institutional Trust
                                 P.O. Box 1357
                         Richmond, Virginia 23286-0109

     Upon receipt of a request in "good order," the Trust will determine the
amount of the net asset value of the redeemed shares, based upon the net asset
value of the Portfolio next determined after the redemption request has been
received. A check for the proceeds will normally be mailed on the next business
day.

     If shares of a Portfolio to be redeemed represent an investment made by
check, the Trust reserves the right not to transmit the redemption proceeds to
the shareholder until the check has been collected, which may take up to 15 days
after the purchase date.

                                       14

<PAGE>


     A redemption request will be considered to have been made in "good order"
if the following conditions are satisfied:

        (1) the request is in writing, states the number of shares to be
            redeemed, and identifies the shareholder's Portfolio account number;

        (2) the request is signed by each registered owner exactly as the shares
            are registered; and

        (3) if the shares to be redeemed were issued in certificate form, the
            certificates are endorsed for transfer (or are accompanied by an
            endorsed stock power) and accompany the redemption request.

   
     Each Portfolio reserves the right to require signature guarantees. A
guarantor of a signature must be an eligible guarantor institution, which term
includes most banks and trust companies, savings associations, credit unions,
and securities brokers or dealers. The purpose of a signature guarantee is to
protect shareholders against the possibility of fraud.
    

     Mentor Distributors may facilitate any redemption request. There is no
extra charge for this service.

     OTHER INFORMATION CONCERNING REDEMPTION. Under unusual circumstances, a
Portfolio may suspend repurchases, or postpone payment for more than seven days,
as permitted by federal securities laws. In addition, each Portfolio reserves
the right, if conditions exist which make cash payments undesirable, to honor
any request for redemption by making payment in whole or in part by securities
valued in the same way as they would be valued for purposes of computing the
Portfolio's per share net asset value. If payment is made in securities, a
shareholder may incur brokerage expenses in converting those securities into
cash.

     EXCHANGE PRIVILEGE. Shareholders may exchange their shares in a Portfolio
for shares of any other Portfolio offered by this Prospectus at their respective
net asset values beginning 15 days after purchase. Shares of certain of the
Portfolios are not available in all states. To exchange shares, simply complete
an exchange authorization form and send it to Mentor Distributors. Exchange
authorization forms are available from the Trust and from Mentor Distributors.
The Trust reserves the right to change or suspend the exchange privilege at any
time. Shareholders would be notified before any such change or suspension.
Consult Mentor Distributors before requesting an exchange.

MENTOR INSTITUTIONAL TRUST

     Mentor Institutional Trust is a Massachusetts business trust organized on
February 8, 1994 as IMG Institutional Trust. A copy of the Agreement and
Declaration of Trust, which is governed by Massachusetts law, is on file with
the Secretary of State of The Commonwealth of Massachusetts.

   
     The Trust is an open-end series management investment company with an
unlimited number of authorized shares of beneficial interest. Shares of the
Trust may, without shareholder approval, be divided into two or more series of
shares representing separate investment portfolios. Any such series of shares
may be further divided without shareholder approval into two or more classes of
shares having such preferences and special or relative rights and privileges as
the Trustees determine. The Trust's shares are currently divided into five
series, four of which are being offered by this Prospectus. Each share has one
vote, with fractional shares voting proportionally. Shares of each class will
vote together as a single class except when required by law or determined by the
Trustees. Shares of the Portfolios are freely transferable, are entitled to
dividends as declared by the Trustees, and, if a Portfolio were liquidated,
would receive the net assets of the Portfolio. The Trust may suspend the sale of
shares at any time and may
    

                                       15

<PAGE>

   
refuse any order to purchase shares. Although the Trust and the Portfolios are
not required to hold annual meetings of its shareholders, shareholders have the
right to call a meeting to elect or remove Trustees, or to take other actions as
provided in the Agreement and Declaration of Trust.
    

     In the interest of economy and convenience, a Portfolio will not issue
certificates for its shares except at the shareholder's request.

CUSTODIAN AND TRANSFER AND DIVIDEND AGENT

     Investors Fiduciary Trust Company, 127 West 10th Street, Kansas City,
Missouri 64105, serves as the Portfolios' custodian. State Street Bank and Trust
Company, c/o Boston Financial Data Services, Inc., 2 Heritage Drive, North
Quincy, Massachusettes 02171, serves as the Portfolios' transfer and dividend
agent.

PERFORMANCE INFORMATION

   
     The INTERMEDIATE DURATION PORTFOLIO, FIXED-INCOME PORTFOLIO, and
INTERNATIONAL PORTFOLIO. Yield and total return data may from time to time be
included in advertisements about the Portfolios. Each Portfolio's "yield" is
calculated by dividing the Portfolio's annualized net investment income per
share during a recent 30-day period by its net asset value on the last day of
that period. "Total return" for the one-, five-, and ten-year periods (or for
the life of a Portfolio, if shorter) through the most recent calendar quarter
represents the average annual compounded rate of return on an investment of
$1,000 in the Portfolio over the period.
    
   
     The CASH MANAGEMENT PORTFOLIO. The Portfolio's yield may from time to time
be included in advertisements about the Portfolio. The Portfolio's "yield" is
calculated by determining the percentage net change, excluding capital changes,
in the value of an investment in one share of the Portfolio over the base
period, and multiplying the net change by 365/7 (or approximately 52 weeks). The
Portfolio's "effective yield" represents a compounding of the yield by adding 1
to the number representing the percentage change in the value of the investment
during the base period, raising that sum to a power equal to 365/7, and
subtracting 1 from the result.
    
   
     A Portfolio's performance may be compared to various indices. See the
Statement of Additional Information. Information may be presented in
advertisements about the Portfolios describing the background and professional
experience of the Portfolios' investment adviser or its investment personnel.
    

   
     All data is based on each Portfolio's past investment results and does not
predict future performance. Investment performance, which will vary, is based on
many factors, including market conditions, the composition of a Portfolio's
investments, and that Portfolio's operating expenses. Investment performance
also often reflects the risks associated with a Portfolio's investment
objectives and policies. These factors should be considered when comparing a
Portfolio's investment results to those of other mutual funds and other
investment vehicles.

EXPENSE SUMMARY

         Expenses  are one of several  factors to consider  when  investing in a
Portfolio.  The following  table  summarizes an investor's  maximum  transaction
costs from  investing in the Portfolio  and expenses the Portfolio  incurred for
the past fiscal year. The Example shows the cumulative expenses  attributable to
a hypothetical $1,000 investment in the Portfolio over specified periods.

        SHAREHOLDER TRANSACTION EXPENSES:
        Maximum Sales Load Imposed on Purchases                        None
        Maximum Sales Load Imposed on Reinvested Dividends             None
        Deferred Sales Load                                            None
        Redemption Fees                                                None
        Exchange Fee                                                   None

               ANNUAL FUND OPERATING EXPENSES:
               (as a percentage of average net assets)
                  Management Fees                                    0.00%
                  12b-1 Fees                                         0.00%
                  Other Expenses (after voluntary
                    expense limitation)*                             0.05%
                    Total Fund Operating Expenses*                   0.05%
- --------------------
   
     *Other Expenses reflect a voluntary expense limitation currently in effect.
In the  absence  of the  expense  limitation,  Other  Expenses  and  Total  Fund
Operating Expenses would have been 0.22%.
    
EXAMPLE

     An  investment  of  $1,000  in the  Portfolio  would  incur  the  following
expenses, assuming 5% annual return and redemption at the end of each period:
   
                          1 year                    $1
                          3 years                   $2
                          5 years                   $3
                         10 years                   $7
    
     This  information is provided to help investors  understand the expenses of
investing in the Portfolio and an  investor's  share of the estimated  operating
expenses of the Portfolio. The Example should not be considered a representation
of future performance; actual expenses may be more or less than those shown.

INVESTMENT OBJECTIVES AND POLICIES
   
     THE INVESTMENT OBJECTIVE OF MENTOR FIXED-INCOME PORTFOLIO IS TO SEEK A HIGH
LEVEL  OF  LONG-TERM  TOTAL  RETURN.  Preservation  of  capital  is a  secondary
objective to the extent  consistent  with the Portfolio's  primary  objective of
seeking a high level of long-term  total return.  The  Portfolio  will invest in
U.S. Government  securities,  fixed-income  securities of corporations and other
private issuers,  mortgage-backed securities, and other asset-backed securities.
The  Portfolio  may also hold a portion  of its  assets in cash or money  market
instruments.  There can, of course,  be no  assurance  that the  Portfolio  will
achieve  its  investment  objectives.  The  Portfolio  is  a  series  of  Mentor
Institutional Trust, and is an open-end, diversified, management investment
company.
    

     The Portfolio will normally  maintain a portfolio  duration of from four to
seven  years.  The  Portfolio's   "portfolio   duration"  at  any  time  is  the
dollar-weighted  average  duration of its portfolio  securities at that time. In
general,  the net asset value of a portfolio  with a longer  portfolio  duration
will increase or decrease to a greater degree in response to changes in interest
rates  than will the net asset  value of a  portfolio  with a shorter  portfolio
duration.  (Typically,  for  example,  the value of a security  with a four-year
duration  will  increase  by  approximately   four  percent  in  response  to  a
one-percent  decline in interest rates, and will decline by  approximately  four
percent in response to a  one-percent  rise in interest  rates;  similarly,  the
value of a security with a seven-year  duration  will increase by  approximately
seven percent in response to a one-percent  decline in interest rates,  and will
decline by  approximately  seven  percent in response to a  one-percent  rise in
interest rates;  and so on.) However,  because issuers of securities with longer
durations typically pay interest on those securities at rates higher than in the
case of securities  with shorter  durations,  the current  income of a portfolio
with a longer  portfolio  duration  will  typically  be  greater  than that of a
portfolio with a shorter portfolio duration.

     Commonwealth  Investment Counsel,  Inc., the Portfolio's investment adviser
("Commonwealth"),  may take full  advantage of the entire range of maturities of
the  securities in which the Portfolio may invest and may,  through the purchase
and  sale  of  securities  with  different  durations,  adjust  the  Portfolio's
portfolio  duration  from  time to  time,  depending  on its  assessment  of the
relative  values  of  securities  of  different  durations  and  maturities  and
expectations of future changes in interest rates. There can be no assurance that
the Portfolio will be able to maintain any particular portfolio duration.

     The  Portfolio's  "total  return"  consists  of current  income,  including
interest payments and discount accruals, plus any increases in the values of the
Portfolio's  investments  (less  any  decreases  in  the  values  of  any of its
investments and  amortizations of premiums).  The Portfolio may seek to increase
its total return by investing in investment-grade  securities which Commonwealth
believes  may  appreciate  in value as a result of changes in interest  rates or
other market factors.

     Traditionally,  a debt  security's  "term to  maturity"  has  been  used to
evaluate the  sensitivity of the  security's  price to changes in interest rates
(the  security's  interest-rate  "volatility").  However,  a security's  term to
maturity measures only the period of time until the last payment of principal or
interest  on the  security,  and does not take into  account  the  timing of the
various  payments of principal or interest to be made prior to the  instrument's
maturity. By contrast, "duration" is a measure of the full stream of payments to
be  received  on a  debt  instrument,  including  both  interest  and  principal
payments,  based on their present values.  Duration measures the periods of time
between the present time and the time when the various  interest  and  principal
payments  are  scheduled  or, in the case of a  callable  bond,  expected  to be
received,  and weights  them by their  present  values.  Duration  can be a more
accurate measure of interest rate volatility than term-to-maturity.  There is no
limit on the average  weighted  maturity the  Portfolio  may  maintain,  and the
Portfolio's  average weighted  maturity will likely be longer than its portfolio
duration.

     There are some situations where the standard duration  calculation does not
properly  reflect  the  interest-rate  volatility  of a security.  For  example,
floating and variable rate securities  often have final  maturities of ten years
or more; however, their interest-rate volatility is determined based principally
on the period of time until their

                                      -4-


<PAGE>

   
interest  rates are reset and on the terms on which  they may be reset.  Another
example where a security's  interest-rate volatility is not properly measured by
the standard  duration  calculation is in the case of mortgage-backed
securities.  The stated final maturity of such  securities may be up to 30
years,  but the actual cash flow on the securities  will be determined by the
prepayment  rates on the underlying mortgage loans. Therefore, the duration of
such a security can change if prepayment rates change. In these and other
similar situations,  Commonwealth will estimate a security's  duration using
analytical  techniques that take into  account  such  factors as the  expected
prepayment  rate on the security  and  how  the  prepayment  rate  might  change
under  various  market conditions. Because calculation of a security's duration
may be based in part on estimates  such as  these  made by  Commonwealth,  the
Portfolio's  ability  to maintain a particular  portfolio duration will depend
on Commonwealth's  ability to make those estimates accurately.
    

     The  Portfolio  will  normally  invest at least  65% of its  total  assets,
determined at the time of investment, in fixed-income securities. A fixed-income
security is a debt security  paying interest at a rate specified in the terms of
the security or determined based on a formula or factors  specified in the terms
of the security.

     The  Portfolio  will only  invest in  securities  of  investment  grade.  A
security  will  be  deemed  to be of  "investment  grade"  if,  at the  time  of
investment  by the  Portfolio,  the  security  is rated at least Baa3 by Moody's
Investors  Service,  Inc.  or BBB- by  Standard  & Poor's  Corporation,  or at a
comparable  rating  by  another  nationally   recognized  rating   organization.
Securities rated Baa or BBB lack outstanding investment characteristics and have
speculative  characteristics  and are subject to greater credit and market risks
than higher-rated securities. The Portfolio will not be required to dispose of a
security  held by it if the  security's  rating  falls below  investment  grade,
although Commonwealth will consider whether continued investment in the security
is consistent with the Portfolio's investment  objectives.  See the Statement of
Additional  Information  for  descriptions  of  securities  ratings  assigned by
Moody's and Standard & Poor's.

     Commonwealth   may  under   unusual   circumstances   implement   temporary
"defensive"  strategies  in order to  reduce  fluctuations  in the  value of the
Portfolio's  assets. At those times, the Portfolio may invest any portion of its
assets  in  cash  or  cash  equivalents,  money  market  instruments,  or  other
short-term, high-quality investments Commonwealth considers consistent with such
defensive  strategies,  and may maintain a portfolio duration shorter than would
otherwise be consistent with its basic investment strategy.

OTHER INVESTMENT PRACTICES AND RISKS

     The Portfolio may engage in the other investment practices described below.
See the Statement of Additional  Information for a more detailed  description of
these practices and certain risks they may involve.

     MORTGAGE-BACKED  SECURITIES.  The Portfolio  may invest in  mortgage-backed
certificates and other securities  representing  ownership interests in mortgage
pools,  including  collateralized  mortgage obligations.  Interest and principal
payments  on the  mortgages  underlying  mortgage-backed  securities  are passed
through  to the  holders  of  the  mortgage-backed  securities.  Mortgage-backed
securities  currently  offer yields higher than those  available from many other
types of fixed-income  securities but because of their prepayment aspects, their
price  volatility  and yield  characteristics  will  change  based on changes in
prepayment  rates.  Generally,  prepayment rates increase if interest rates fall
and  decrease  if  interest  rates  rise.  For  many  types  of  mortgage-backed
securities,   this  can  result  in  unfavorable  changes  in  price  and  yield
characteristics  in  response  to changes  in  interest  rates and other  market
conditions.   For  example,  as  a  result  of  their  prepayment  aspects,  the
Portfolio's   mortgage-backed   securities   have  less  potential  for  capital
appreciation  during periods of declining interest rates than other fixed-income
securities  of  comparable  maturities,  although  such  obligations  may have a
comparable  or greater risk of decline in market value during  periods of rising
interest rates.

     Mortgage-backed securities have yield and maturity characteristics that are
dependent on the  mortgages  underlying  them.  Thus,  unlike  traditional  debt
securities, which may pay a fixed rate of interest until maturity

                                      -5-


<PAGE>



when the entire principal amount comes due, payments on these securities include
both interest and a partial payment of principal.  In addition to scheduled loan
amortization,  payments of principal may result from the  voluntary  prepayment,
refinancing,  or foreclosure of the underlying  mortgage loans. Such prepayments
may significantly shorten the effective durations of mortgage-backed securities,
especially during periods of declining interest rates. Similarly, during periods
of  rising   interest  rates,  a  reduction  in  the  rate  of  prepayments  may
significantly lengthen the effective durations of such securities.

     OTHER  ASSET-BACKED  SECURITIES.  The  Portfolio  may invest in  securities
representing   interests   in  other  types  of   financial   assets,   such  as
automobile-finance  receivables or credit-card receivables.  Such securities are
subject to many of the same risks as are mortgage-backed  securities,  including
prepayment risks,  refinancing risks, and risks of foreclosure.  They may or may
not be secured by the receivables  themselves or may be unsecured obligations of
their issuers.

     WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS.  The Portfolio may purchase
securities on a "whenissued" basis. The price of such securities is fixed at the
time the  commitment  to  purchase  is made,  but  delivery  and payment for the
when-issued  securities take place at a later date (normally within one month of
purchase).  The  Portfolio  may also purchase  securities  for future  delivery.
"When-issued"  securities and forward  commitments  may increase the Portfolio's
overall investment exposure and may result in losses.



   
     OPTIONS AND FUTURES. The Portfolio may buy and sell call and put options to
hedge against changes in net asset value or to realize a greater current return.
In addition, through the purchase and sale of futures contracts and related
options, the Portfolio may at times seek to hedge against fluctuations in net
asset value and, to the extent consistent with applicable law, to increase its
investment return.
    
   
     The Portfolio's ability to engage in options and futures strategies will
depend on the availability of liquid markets in such instruments. It is
impossible to predict the amount of trading interest that may exist in various
types of options or futures contracts. Therefore, there is no assurance that the
Portfolio will be able to utilize these instruments effectively for the purposes
stated above. Transactions in options and futures involve certain risks which
are described below and in the Statement of Additional Information.
    
   
     Transactions in options and futures contracts involve brokerage costs and
may require the Portfolio to segregate assets to cover its outstanding
positions. For more information, see the Statement of Additional Information.
    
   
     INDEX FUTURES AND OPTIONS. The Portfolio may buy and sell index futures
contracts ("index futures") and options on index futures and on indices for
hedging purposes (or may purchase warrants whose value is based on the value
from time to time of one or more foreign securities indices). An "index futures"
is a contract to buy or sell units of a particular bond or stock index at an
agreed price on a specified future date. Depending on the change in value of the
index between the time when the Portfolio enters into and terminates an index
futures or option transaction, the Portfolio realizes a gain or loss. The
Portfolio may also, to the extent consistent with applicable law, buy and sell
index futures and options to incerase its investment return.
    
   
     RISKS REALTED TO OPTIONS AND FUTURES STRATEGIES. Options and futures
transactions involve costs and may result in losses. Certain risks arise because
of the possibility of imperfect correlations between movements in the prices of
futures and options and movements in the prices of the underlying security or
index or of the securities held by the Portfolio that are the subject of a
hedge. The successful use by the Portfolio of the strategies described above
further depends on the ability of Commonwealth to forecast market movements
correctly. Other risks arise from the Portfolio's potential inability to close
out futures or options positions. Although the portfolio will enter into options
or futures transactions only if Commonwealth believes that a liquid secondary
market exists for such options or futures contracts, there can be no assurance
that the Portfolio will be able to effect closing transactions at any particular
time or at an acceptable price. Certain provisions of the Internal Revenue Code
may limit the Portfolio's ability to engage in options and futures transactions.
    
   
     The Portfolio generally expects that its options transactions
will be conducted on recognized exchanges. The Portfolio may in certain
instances purchase and sell options in the over-the-counter markets. The
Portoflio's ability to terminate options in the over-the-counter markets may be
more limited than for exchange-traded options and may also involve the risk that
securities dealers participating in such transactions would be unable to meet
their obligations to the Portfolio. The Portfolio will, however, engage in
over-the-counter transactions only when appropriate exchange-traded transactions
are unavailable and when, in the opinion of Commonwealth, the pricing mechanism
and liquidity of the over-the-counter markets are satisfactory and the
participants are responsible parties likely to meet their obligations.
    
   
     The Portfolio will not purchase futures or options on futures or sell
futures if as a result the sum of the initial margin deposits on the Portfolio's
existing futures positions and premiums paid for outstanding options on futures
contracts would exceed 5% of the Portfolio's assets. (For options that are
"in-the-money" at the time of purchase, the amount by which the option is
"in-the-money" is excluded from this calculation.)
    

     REPURCHASE AGREEMENTS.  The Portfolio may enter into repurchase agreements.
Under a repurchase  agreement,  the Portfolio  purchases a debt instrument for a
relatively  short  period  (usually  not more than one  week),  which the seller
agrees to repurchase  at a fixed time and price,  representing  the  Portfolio's
cost plus interest.  The Portfolio will enter into  repurchase  agreements  only
with commercial  banks and with registered  broker-dealers  who are members of a
national securities exchange or market makers in government securities, and only
if the debt instrument subject to the repurchase  agreement is a U.S. Government
security.  Although Commonwealth will monitor repurchase agreement  transactions
to ensure that they will be fully  collateralized  at all times,  the  Portfolio
bears a risk of loss if the  other  party  defaults  on its  obligation  and the
Portfolio is delayed or prevented  from  exercising its rights to dispose of the
collateral.  If  the  other  party  should  become  involved  in  bankruptcy  or
insolvency  proceedings,  it is possible that the Portfolio may be treated as an
unsecured  creditor and be required to return the  underlying  collateral to the
other party's estate.

     As a matter  of  policy,  the  Trustees  will  not  materially  change  the
Portfolio's investment objectives without shareholder approval. (Any such change
could,  of course,  result in a change in the nature of the  securities in which
the  Portfolio  may  invest  and the  risks  involved  in an  investment  in the
Portfolio.)

MANAGEMENT OF THE PORTFOLIO
   
     The Trustees of the Trust are  responsible  for  generally  overseeing  the
conduct of the Trust's business.  COMMONWEALTH INVESTMENT COUNSEL, INC., located
at 901 East Byrd Street, Richmond, Virginia 23219, acts as investment adviser to
the  Portfolio  pursuant  to  a  Management   Contract  between  the  Trust  and
Commonwealth.  MENTOR INVESTMENT GROUP, INC.  ("Mentor") serves as administrator
to the Portfolio. Neither Commonwealth nor Mentor receives compensation from the
Portfolio  for the  performance  of such  services.  Mentor  has  agreed to bear
certain  expenses of the Portfolio  pursuant to a voluntary  expense  limitation
currently in effect. This limitation may be terminated at any time. Commonwealth
is a wholly owned  subsidiary of Mentor,  which is a wholly owned  subsidiary of
Wheat First Butcher Singer,  Inc.  ("Wheat First Butcher  Singer").  Wheat First
Butcher  Singer,   through  other  subsidiaries,   also  engages  in  securities
brokerage,  investment banking, and related businesses.  Commonwealth  currently
has  assets  under  management  of  approximately  $4  billion,  and  serves  as
investment  adviser  to Cash  Resource  Trust,  an  open-end  series  investment
company, Mentor Balanced Portfolio, Mentor Quality Income Portfolio,  Mentor
Short-Duration  Income Portfolio, SNAP Fund, and America's Utility Fund, Inc.,
each of which is an open-end  investment  company,  and Mentor Income Fund,
Inc., a closed-end investment company.
    
   
     Subject to the general oversight of the Trustees, Commonwealth, as
investment adviser, manages the Portfolio in accordance with the stated policies
of the Portfolio. All investment decisions for the Portfolio are made by an
investment committee at Commonwealth which is made up of investment
professionals of that firm.
    

     Commonwealth  makes  investment  decisions for the Portfolio and places the
purchase  and  sale  orders  for  the  Portfolio's  portfolio  transactions.  In
selecting  broker-dealers,  Commonwealth  may consider  research  and  brokerage
services furnished to it and its affiliates. Subject to seeking the best overall
terms  available,  Commonwealth  may consider  sales of shares of the  Portfolio
(and, if permitted by law, of other portfolios in the Mentor family) as a factor
in the selection of  broker-dealers  to execute  portfolio  transactions for the
Portfolio.
   
     PORTFOLIO TURNOVER.  The length of time the Portfolio has held a particular
security is not generally a consideration in investment  decisions.  A change in
the  securities  held by the  Portfolio is known as  "portfolio  turnover." As a
result of the Portfolio's  investment policies,  under certain market conditions
the Portfolio's  portfolio turnover rate may be higher than that of other mutual
funds.  Portfolio  turnover  generally  involves some expense to the  Portfolio,
including  brokerage  commissions or dealer mark-ups and other transaction costs
on  the  sale  of  securities  and  reinvestment  in  other   securities.   Such
transactions may result in realization of taxable capital gains.  The portfolio
turnover rate for the fiscal period ended October 31,  1995  for the  Portfolio
is  contained  in the  section  "Financial Highlights."
    


HOW THE PORTFOLIO VALUES ITS SHARES

     The Portfolio  calculates the net asset value of its shares by dividing the
total  value of its  assets,  less  liabilities,  by the  number  of its  shares
outstanding.  Shares are  valued as of the close of  regular  trading on the New
York Stock  Exchange  each day the Exchange is open.  Portfolio  securities  for
which  market  quotations  are  readily  available  are stated at market  value.
Short-term  investments  that  will  mature  in 60 days or less  are  stated  at
amortized  cost,  which has been determined to approximate the fair market value
of such  investments.  All other  securities and assets are valued at their fair
values.

HOW DISTRIBUTIONS ARE MADE

     The  Portfolio  distributes  net  investment  income  quarterly and any net
realized capital gains at least annually.  Distributions  from capital gains are
made after  applying  any  available  capital  loss  carryovers.  All  Portfolio
distributions  will be  invested  in  additional  Portfolio  shares,  unless the
shareholder instructs the Portfolio otherwise.

                                      -7-

TAXES

     The Portfolio  intends to qualify as a "regulated  investment  company" for
federal  income  tax  purposes  and to meet  all  other  requirements  that  are
necessary  for it to be  relieved  of  federal  taxes  on  income  and  gains it
distributes to shareholders.  The Portfolio will distribute substantially all of
its net investment income and capital gain net income on a current basis.

     The following is intended  principally for shareholders  subject to federal
income taxation:

     All Portfolio distributions,  other than exempt-interest dividends, will be
taxable to shareholders as ordinary income, except that any distributions of net
capital gain will be taxed as long-term  capital gain,  regardless of how long a
shareholder has held the shares  (although the loss on a sale of shares held for
six months or less will be treated as  long-term  capital  loss to the extent of
any  capital  gain   distribution   received  with  respect  to  those  shares).
Distributions  will be taxable as described above whether received in cash or in
shares through the reinvestment of  distributions.  Early in each year the Trust
will notify  shareholders of the amount and tax status of distributions  paid by
the Portfolio for the preceding  year. In buying or selling  securities  for the
Portfolio,  Commonwealth  will not  normally  take into  account  the effect any
purchase or sale of securities will have on the tax positions of the Portfolio's
shareholders.

     The foregoing is a summary of certain  federal income tax  consequences  of
investing in the Portfolio.  Dividends and distributions  also may be subject to
state and local  taxes.  Shareholders  are urged to consult  their tax  advisers
regarding  specific  questions as to federal,  state,  or local taxes.  Non-U.S.
investors  should consult their tax advisers  concerning the tax consequences of
ownership  of  shares  of  the  Portfolio,   including  the   possibility   that
distributions  may be  subject  to a 30%  United  States  withholding  tax (or a
reduced rate of withholding provided by treaty).

PURCHASE OF SHARES

     Shares of the  Portfolio  are sold at the net asset  value next  determined
after a purchase  order is received by the Portfolio.  Purchase  orders that are
received  prior to the close of  trading  on the New York  Stock  Exchange  on a
particular  day are priced  according to the net asset value  determined on that
day.

     Mentor Distributors, Inc. ("Mentor Distributors"), 901 East Byrd Street,
Richmond, Virginia 23219, serves as distributor of the Portfolio's shares.
Mentor Distributors is not obligated to sell any specific amount of shares of
the Portfolio.

     An  investor  may make an initial  purchase of shares of the  Portfolio  by
submitting a completed Trust  application  along with a purchase  order,  and by
making  payment  to Mentor  Distributors.  Investors  will be  required  to make
minimum initial  investments of $500,000 in the Portfolio and minimum subsequent
investments of $25,000.  Investments made through advisory  accounts  maintained
with investment  advisers  registered under the Investment  Advisers Act of 1940
(including  "wrap"  accounts)  are  not  subject  to  these  minimum  investment
requirements. The Portfolio reserves the right at any time to change the initial
and subsequent investment minimums required of investors.

     Shares  of  the  Portfolio  may  be  purchased  by (i)  paying  cash,  (ii)
exchanging securities acceptable to Commonwealth, or (iii) a combination of such
securities  and cash.  Purchase  of  shares of the  Portfolio  in  exchange  for
securities is subject in each case to the determination by Commonwealth that the
securities  to be  exchanged  are  acceptable  for  purchase  by the  Portfolio.
Securities  accepted by  Commonwealth  in exchange for Portfolio  shares will be
valued  in the  same  manner  as the  Portfolio's  assets  as of the time of the
Portfolio's next  determination  of net asset value after such  acceptance.  All
dividends  and  subscription  or other rights which are  reflected in the market
price of accepted securities at the time of valuation become the property of the
Portfolio

                                      -8-


<PAGE>



and must be delivered  to the  Portfolio  upon receipt by the investor  from the
issuer.  A gain or loss for federal  income tax purposes  would be realized upon
the  exchange  by an  investor  that is  subject  to  federal  income  taxation,
depending upon the investor's  basis in the securities  tendered.  A shareholder
who  wishes  to  purchase   shares  by  exchanging   securities   should  obtain
instructions by calling Mentor Distributors at 1-800-869-6042.

     In all cases  Commonwealth  or Mentor  Distributors  reserves  the right to
reject any particular investment.

REDEMPTION OF SHARES

     A shareholder  may redeem all or any portion of its shares in the Portfolio
at any  time  upon  request,  by  following  the  procedures  set  forth  below.
Redemptions  will be effected at the net asset value per share of the  Portfolio
next determined after the receipt by the Portfolio of redemption instructions in
"good order" as described below.  Shares may be redeemed by submitting a written
request for redemption to Mentor Distributors,  or to the Trust at the following
address:

                           Mentor Institutional Trust
                                 P.O. Box 1357
                         Richmond, Virginia 23286-0109

     Upon  receipt of a request in "good  order," the Trust will  determine  the
amount of the net asset value of the redeemed  shares,  based upon the net asset
value of the Portfolio next  determined  after the  redemption  request has been
received.  A check for the proceeds will normally be mailed on the next business
day.

     If shares of the Portfolio to be redeemed  represent an investment  made by
check,  the Trust reserves the right not to transmit the redemption  proceeds to
the shareholder until the check has been collected, which may take up to 15 days
after the purchase date.

     A redemption  request will be  considered to have been made in "good order"
if the following conditions are satisfied:

              (1)   the request is in writing, states the number of shares to be
                    redeemed, and identifies the shareholder's Portfolio account
                    number;

              (2)   the request is signed by each registered owner exactly as
                    the shares are registered; and

              (3)   if the  shares to be  redeemed  were  issued in  certificate
                    form,  the  certificates  are  endorsed for transfer (or are
                    accompanied  by an endorsed  stock power) and  accompany the
                    redemption request.

     The  Portfolio  reserves  the  right to  require  signature  guarantees.  A
guarantor of a signature must be an eligible guarantor  institution,  which term
includes most banks and trust companies,  savings  associations,  credit unions,
and securities  brokers or dealers.  The purpose of a signature  guarantee is to
protect Portfolio shareholders against the possibility of fraud.

     Mentor  Distributors  may facilitate any  redemption  request.  There is no
extra charge for this service.

     OTHER INFORMATION CONCERNING REDEMPTION.  Under unusual circumstances,  the
Portfolio may suspend repurchases, or postpone payment for more than seven days,
as permitted by federal securities laws. In addition, the Portfolio reserves the
right, if conditions  exist which make cash payments  undesirable,  to honor any
request  for  redemption  by making  payment  in whole or in part by  securities
valued in the same way as they would be

                                      -9-


<PAGE>



valued for purposes of computing the  Portfolio's  per share net asset value. If
payment is made in securities,  a shareholder  may incur  brokerage  expenses in
converting those securities into cash.

     EXCHANGE PRIVILEGE. Shareholders may exchange their shares in the Portfolio
for shares of certain other Portfolios  comprising the Trust at their respective
net asset values beginning 15 days after purchase.  Contact Mentor  Distributors
for a prospectus of any of those Portfolios. Shares of certain of the Portfolios
are not available in all states. To exchange shares, simply complete an exchange
authorization form and send it to Mentor  Distributors.  Exchange  authorization
forms  are  available  from the Trust and from  Mentor  Distributors.  The Trust
reserves  the right to change or suspend  the  exchange  privilege  at any time.
Shareholders  would be notified  before any such change or  suspension.  Consult
Mentor Distributors before requesting an exchange.

MENTOR INSTITUTIONAL TRUST

     Mentor  Institutional Trust is a Massachusetts  business trust organized on
February  8,  1994  as IMG  Institutional  Trust.  A copy of the  Agreement  and
Declaration of Trust,  which is governed by  Massachusetts  law, is on file with
the Secretary of State of The Commonwealth of Massachusetts.
   
     The Trust is an open-end series management investment company with an
unlimited number of authorized shares of beneficial interest.  Shares of the
Trust may, without shareholder  approval, be divided into two or more series of
shares representing separate investment portfolios. Any such series of shares
may be further divided without shareholder  approval into two or more classes of
shares having such  preferences and special or relative rights and privileges as
the Trustees  determine.  The Trust's  shares are  currently  divided into five
series, one representing the Portfolio, the others representing other Portfolios
with varying investment  objectives and policies.  Each share has one vote, with
fractional shares voting proportionally. Shares of each class will vote together
as a single class except when  required by law or  determined  by the  Trustees.
Shares of the  Portfolio are freely  transferable,  are entitled to dividends as
declared by the Trustees,  and, if the Portfolio were liquidated,  would receive
the net assets of the Portfolio. The Trust may suspend the sale of shares at any
time and may  refuse any order to  purchase  shares.  Although  the Portfolio
and the Trust are not required to hold  annual  meetings of its  shareholders,
shareholders  have the right to call a meeting to elect or remove Trustees, or
to take other actions as provided in the Agreement and Declaration of Trust.
    

     In the interest of economy and  convenience,  the Portfolio  will not issue
certificates for its shares except at the shareholder's request.

CUSTODIAN AND TRANSFER AND DIVIDEND AGENT

     Investors Fiduciary Trust Company, 127 West 10th Street, Kansas City,
Missouri 64105, serves as the Portfolio's custodian.  State Street Bank and
Trust Company, c/o Boston Financial Data Services, Inc., 2 Heritage Drive,

dividend agent.

PERFORMANCE INFORMATION

   
     Yield  and  total  return  data  may  from  time  to time  be  included  in
advertisements  about the Portfolio.  The  Portfolio's  "yield" is calculated by
dividing the  Portfolio's  annualized net  investment  income per share during a
recent  30-day  period  by its net asset  value on the last day of that  period.
"Total  return" for the one-, five- and ten-year periods (or for the life of the
Portfolio, if shorter) through the most recent  calendar quarter  represents the
average annual compounded rate of return on an investment of $1,000 in the
Portfolio  over the period.  The  Portfolio's  performance  may be  compared to
various indices. See the Statement of Additional Information. Information may be
presented in advertisements  about the Portfolio  describing the background and
professional experience of the Portfolio's  investment adviser or its investment
personnel.

     All data is based on the Portfolio's  past investment  results and does not
predict future performance. Investment performance, which will vary, is based on
many factors,  including market  conditions,  the composition of the Portfolio's
investments, and the Portfolio's operating expenses. Investment performance also
often reflects the risks associated with the Portfolio's  investment  objectives
and policies.  These factors should be considered when comparing the Portfolio's
investment results to those of other mutual funds and other investment vehicles.

EXPENSE SUMMARY

         Expenses  are one of several  factors to consider  when  investing in a
Portfolio.  The following  table  summarizes an investor's  maximum  transaction
costs from  investing in the Portfolio  and expenses the Portfolio  incurred for
the past fiscal year. The Example shows the cumulative expenses  attributable to
a hypothetical $1,000 investment in the Portfolio over specified periods.

        SHAREHOLDER TRANSACTION EXPENSES:
        Maximum Sales Load Imposed on Purchases                         None
        Maximum Sales Load Imposed on Reinvested Dividends              None
        Deferred Sales Load                                             None
        Redemption Fees                                                 None
        Exchange Fee                                                    None

               ANNUAL FUND OPERATING EXPENSES:
               (as a percentage of average net assets)
                  Management Fees                                    0.00%
                  12b-1 Fees                                         0.00%
                  Other Expenses (after voluntary
                    expense limitation)*                             0.05%
                    Total Fund Operating Expenses*                   0.05%
- --------------------
   
     *Other Expenses reflect a voluntary expense limitation currently in effect.
In the  absence  of the  expense  limitation,  Other  Expenses  and  Total  Fund
Operating Expenses would have been 0.25%.
    
EXAMPLE

     An  investment  of  $1,000  in the  Portfolio  would  incur  the  following
expenses, assuming 5% annual return and redemption at the end of each period:

                          1 year                    $1
                          3 years                   $2

     This  information is provided to help investors  understand the expenses of
investing in the Portfolio and an  investor's  share of the estimated  operating
expenses of the Portfolio. The Example should not be considered a representation
of future performance; actual expenses may be more or less than those shown.

INVESTMENT OBJECTIVES AND POLICIES
   
     THE INVESTMENT  OBJECTIVE OF MENTOR  INTERMEDIATE  DURATION PORTFOLIO IS TO
SEEK A HIGH  LEVEL OF  LONG-TERM  TOTAL  RETURN.  Preservation  of  capital is a
secondary  objective  to the  extent  consistent  with the  Portfolio's  primary
objective of seeking a high level of long-term total return.  The Portfolio will
invest in U.S. Government  securities,  fixed-income  securities of corporations
and other private issuers,  mortgage-backed  securities,  and other asset-backed
securities. The Portfolio may also hold a portion of its assets in cash or money
market  instruments.  There can, of course,  be no assurance  that the Portfolio
will  achieve its  investment  objectives.  The  Portfolio is a series of Mentor
Institutional Trust, and is an open-end, diversified, management investment
company.

    

     The Portfolio  will normally  maintain a portfolio  duration of from two to
five  years.   The  Portfolio's   "portfolio   duration"  at  any  time  is  the
dollar-weighted  average  duration of its portfolio  securities at that time. In
general,  the net asset value of a portfolio  with a longer  portfolio  duration
will increase or decrease to a greater degree in response to changes in interest
rates  than will the net asset  value of a  portfolio  with a shorter  portfolio
duration.  (Typically,  for  example,  the value of a  security  with a two-year
duration will increase by approximately two percent in response to a one-percent
decline in interest  rates,  and will  decline by  approximately  two percent in
response to a  one-percent  rise in interest  rates;  similarly,  the value of a
security with a five-year  duration will increase by approximately  five percent
in response to a one-percent decline in interest rates, and will decline by

                                      -3-


<PAGE>



approximately  five percent in response to a one-percent rise in interest rates;
and so on.)  However,  because  issuers  of  securities  with  longer  durations
typically  pay interest on those  securities at rates higher than in the case of
securities  with shorter  durations,  the current  income of a portfolio  with a
longer  portfolio  duration  will  typically be greater than that of a portfolio
with a shorter portfolio duration.

("Commonwealth"),  may take full  advantage of the entire range of maturities of
the  securities in which the Portfolio may invest and may,  through the purchase
and  sale  of  securities  with  different  durations,  adjust  the  Portfolio's
portfolio  duration  from  time to  time,  depending  on its  assessment  of the
relative  values  of  securities  of  different  durations  and  maturities  and
expectations of future changes in interest rates. There can be no assurance that
the Portfolio will be able to maintain any particular portfolio duration.

     The  Portfolio's  "total  return"  consists  of current  income,  including
interest payments and discount accruals, plus any increases in the values of the
Portfolio's  investments  (less  any  decreases  in  the  values  of  any of its
investments and  amortizations of premiums).  The Portfolio may seek to increase
its total return by investing in investment-grade  securities which Commonwealth
believes  may  appreciate  in value as a result of changes in interest  rates or
other market factors.

     Traditionally,  a debt  security's  "term to  maturity"  has  been  used to
evaluate the  sensitivity of the  security's  price to changes in interest rates
(the  security's  interest-rate  "volatility").  However,  a security's  term to
maturity measures only the period of time until the last payment of principal or
interest  on the  security,  and does not take into  account  the  timing of the
various  payments of principal or interest to be made prior to the  instrument's
maturity. By contrast, "duration" is a measure of the full stream of payments to
be  received  on a  debt  instrument,  including  both  interest  and  principal
payments,  based on their present values.  Duration measures the periods of time
between the present time and the time when the various  interest  and  principal
payments  are  scheduled  or, in the case of a  callable  bond,  expected  to be
received,  and weights  them by their  present  values.  Duration  can be a more
accurate measure of interest rate volatility than term-to-maturity.  There is no
limitation on the average weighted maturity the Portfolio may maintain,  and the
Portfolio's  average weighted  maturity will likely be longer than its portfolio
duration.

   
     There are some situations where the standard duration  calculation does not
properly  reflect  the  interest-rate  volatility  of a security.  For  example,
floating and variable rate securities  often have final  maturities of ten years
or more; however, their interest-rate volatility is determined based principally
on the period of time until their  interest  rates are reset and on the terms on
which  they may be  reset.  Another  example  where a  security's  interest-rate
volatility is not properly measured by the standard  duration  calculation is in
the case of mortgage-backed securities.  The stated final maturity of such
securities may be up to 30  years,  but the  actual  cash  flow on the
securities  will be determined by the prepayment rates on the underlying
mortgage loans.  Therefore, the duration of such a security can change if
prepayment rates change.  In these and other similar  situations,  Commonwealth
will estimate a security's duration using analytical techniques that take into
account such factors as the expected  prepayment  rate on the security and how
the prepayment rate might change under various  market conditions.  Because
calculation  of a security's duration may be based in part on estimates  such as
these made by  Commonwealth, the Portfolio's ability to maintain a particular
portfolio duration will depend on Commonwealth's ability to make those estimates
accurately.
    
     The  Portfolio  will  normally   invest  in  fixed-income   securities.   A
fixed-income  security is a debt security paying interest at a rate specified in
the terms of the security or determined based on a formula or factors  specified
in the terms of the security.

     The  Portfolio  will only  invest in  securities  of  investment  grade.  A
security  will  be  deemed  to be of  "investment  grade"  if,  at the  time  of
investment  by the  Portfolio,  the  security  is rated at least Baa3 by Moody's
Investors  Service,  Inc.  or BBB- by  Standard  & Poor's  Corporation,  or at a
comparable rating by another

                                      -4-


<PAGE>



nationally  recognized  rating  organization.  Securities  rated Baa or BBB lack
outstanding investment characteristics and have speculative  characteristics and
are subject to greater credit and market risks than higher-rated securities. The
Portfolio  will not be  required  to  dispose  of a  security  held by it if the
security's  rating falls below  investment  grade,  although  Commonwealth  will
consider  whether  continued  investment in the security is consistent  with the
Portfolio's investment  objectives.  See the Statement of Additional Information
for  descriptions  of  securities  ratings  assigned by Moody's  and  Standard &
Poor's.

     Commonwealth   may  under   unusual   circumstances   implement   temporary
"defensive"  strategies  in order to  reduce  fluctuations  in the  value of the
Portfolio's  assets. At those times, the Portfolio may invest any portion of its
assets  in  cash  or  cash  equivalents,  money  market  instruments,  or  other
short-term, high-quality investments Commonwealth considers consistent with such
defensive  strategies,  and may maintain a portfolio duration shorter than would
otherwise be consistent with its basic investment strategy.

OTHER INVESTMENT PRACTICES AND RISKS

     The Portfolio may engage in the other investment practices described below.
See the Statement of Additional  Information for a more detailed  description of
these practices and certain risks they may involve.

     MORTGAGE-BACKED  SECURITIES.  The Portfolio  may invest in  mortgage-backed
certificates and other securities  representing  ownership interests in mortgage
pools,  including  collateralized  mortgage obligations.  Interest and principal
payments  on the  mortgages  underlying  mortgage-backed  securities  are passed
through  to the  holders  of  the  mortgage-backed  securities.  Mortgage-backed
securities  currently  offer yields higher than those  available from many other
types of fixed-income  securities but because of their prepayment aspects, their
price  volatility  and yield  characteristics  will  change  based on changes in
prepayment  rates.  Generally,  prepayment rates increase if interest rates fall
and  decrease  if  interest  rates  rise.  For  many  types  of  mortgage-backed
securities,   this  can  result  in  unfavorable  changes  in  price  and  yield
characteristics  in  response  to changes  in  interest  rates and other  market
conditions.   For  example,  as  a  result  of  their  prepayment  aspects,  the
Portfolio's   mortgage-backed   securities   have  less  potential  for  capital
appreciation  during periods of declining interest rates than other fixed-income
securities  of  comparable  maturities,  although  such  obligations  may have a
comparable  or greater risk of decline in market value during  periods of rising
interest rates.

     Mortgage-backed securities have yield and maturity characteristics that are
dependent on the  mortgages  underlying  them.  Thus,  unlike  traditional  debt
securities,  which may pay a fixed  rate of  interest  until  maturity  when the
entire  principal amount comes due,  payments on these  securities  include both
interest  and a partial  payment of  principal.  In addition to  scheduled  loan
amortization,  payments of principal may result from the  voluntary  prepayment,
refinancing,  or foreclosure of the underlying  mortgage loans. Such prepayments
may significantly shorten the effective durations of mortgage-backed securities,
especially during periods of declining interest rates. Similarly, during periods
of  rising   interest  rates,  a  reduction  in  the  rate  of  prepayments  may
significantly lengthen the effective durations of such securities.

     OTHER  ASSET-BACKED  SECURITIES.  The  Portfolio  may invest in  securities
representing   interests   in  other  types  of   financial   assets,   such  as
automobile-finance  receivables or credit-card receivables.  Such securities are
subject to many of the same risks as are mortgage-backed  securities,  including
prepayment risks,  refinancing risks, and risks of foreclosure.  They may or may
not be secured by the receivables  themselves or may be unsecured obligations of
their issuers.

     WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS.  The Portfolio may purchase
securities on a "when-issued" basis. The price of such securities is fixed at
the time the  commitment  to  purchase  is made,  but  delivery  and payment for
the when-issued  securities take place at a later date (normally within one
month of purchase).  The  Portfolio  may also purchase  securities  for future
delivery. "When-issued"  securities and forward  commitments  may increase the
Portfolio's overall investment exposure and may result in losses.

                                      -5-


<PAGE>

   
     OPTIONS AND FUTURES. The Portfolio may buy and sell call and put options to
hedge against changes in net asset value or to realize a greater current return.
In addition, through the purchase and sale of futures contracts and related
options, the Portfolio may at times seek to hedge against fluctuations in net
asset value and, to the extent consistent with applicable law, to increase its
investment return.
    
   
     The Portfolio's ability to engage in options and futures strategies will
depend on the availability of liquid markets in such instruments. It is
impossible to predict the amount of trading interest that may exist in various
types of options or futures contracts. Therefore, there is no assurance that the
Portfolio will be able to utilize these instruments effectively for the purposes
stated above. Transactions in options and futures involve certain risks which
are described below and in the Statement of Additional Information.
    
   
     Transactions in options and futures contracts involve brokerage costs and
may require the Portfolio to segregate assets to cover its outstanding
positions. For more information, see the Statement of Additional Information.
    
   
     INDEX FUTURES AND OPTIONS. The Portfolio may buy and sell index futures
contracts ("index futures") and options on index futures and on indices or
hedging purposes (or may purchase warrants whose value is based on the value
from time to time of one or more foreign securities indices). An "index futures"
is a contract to buy or sell units of a particular bond or stock index at an
agreed price on a specified future date. Depending on the change in value of the
index between the time when the Portfolio enters into and terminates an index
futures or option transaction, the Portfolio realizes a gain or loss. The
Portfolio may also, to the extent consistent with applicable law, buy and sell
index futures and options to increase its investment return.
    
   
     RISKS RELATED TO OPTIONS AND FUTURES STRATEGIES. Options and futures
transactions involve costs and may result in losses. Certain risks arise because
of the possibility of imperfect correlations between the movements in the prices
of futures and options and movements in the prices of the underlying security or
index or of the securities held by the Portfolio that are the subject of a
hedge. The successful use by the Portfolio of the strategies described above
further depends on the ability of Commonwealth to forecast market movements
correctly. Other risks arise from the Portfolio's potential inability to close
out futures or options positions. Although the Portfolio will enter into options
or futures transactions only if Commonwealth believes that a liquid secondary
market exists for such options or futures contracts, there can be no assurance
that the Portfolio will be able to effect closing transactions at any particular
time or at an acceptable price. Certain provisions of the Internal Revenue Code
may limit the Portfolio's ability to engage in options and futures transactions.
    
   
     The Portfolio generally expects that its options transactions will be
conducted on recognized exchanges. The Portfolio may in certain instances
purchase and sell options in the over-the-counter markets. The Portfolio's
ability to terminate options in the over-the-counter markets may be more limited
than for exchange-traded options and may also involve the risk that securities
dealers participating in such transactions would be unable to meet their
obligations to the Portfolio. The Portfolio will, however, engage in
over-the-counter transactions only when appropriate exchange-traded transactions
are unavailable and when, in the opinion of Commonwealth, the pricing mechanism
and liquidity of the over-the-counter markets are satisfactory and the
participants are responsible parties likely to meet their obligations.
    
   
     The Portfolio will not purchase futures or options on futures on sell
futures if as a result the sum of the initial margin deposits on the Portfolio's
existing futures positions and premiums paid for outstanding options on futures
contracts would exceed 5% of the Portfolio's assets. (For options that are
"in-the-money" at the time of purchase, the amount by which the option is
"in-the-money" is excluded from this calculation.)
    

     REPURCHASE AGREEMENTS.  The Portfolio may enter into repurchase agreements.
Under a repurchase  agreement,  the Portfolio  purchases a debt instrument for a
relatively  short  period  (usually  not more than one  week),  which the seller
agrees to repurchase  at a fixed time and price,  representing  the  Portfolio's
cost plus interest.  The Portfolio will enter into  repurchase  agreements  only
with commercial  banks and with registered  broker-dealers  who are members of a
national securities exchange or market makers in government securities, and only
if the debt instrument subject to the repurchase  agreement is a U.S. Government
security.  Although Commonwealth will monitor repurchase agreement  transactions
to ensure that they will be fully  collateralized  at all times,  the  Portfolio
bears a risk of loss if the  other  party  defaults  on its  obligation  and the
Portfolio is delayed or prevented  from  exercising its rights to dispose of the
collateral.  If  the  other  party  should  become  involved  in  bankruptcy  or
insolvency  proceedings,  it is possible that the Portfolio may be treated as an
unsecured  creditor and be required to return the  underlying  collateral to the
other party's estate.



     As a matter  of  policy,  the  Trustees  will  not  materially  change  the
Portfolio's investment objectives without shareholder approval. (Any such change
could,  of course,  result in a change in the nature of the  securities in which
the  Portfolio  may  invest  and the  risks  involved  in an  investment  in the
Portfolio.)

MANAGEMENT OF THE PORTFOLIO

     The Trustees of the Trust are  responsible  for  generally  overseeing  the
conduct of the Trust's business.  COMMONWEALTH INVESTMENT COUNSEL, INC., located
at 901 East Byrd Street, Richmond, Virginia 23219, acts as investment adviser to
the  Portfolio  pursuant  to  a  Management   Contract  between  the  Trust  and
Commonwealth.  MENTOR INVESTMENT GROUP, INC.  ("Mentor") serves as administrator
to the Portfolio. Neither Commonwealth nor Mentor receives compensation from the
Portfolio  for the  performance  of such  services.  Mentor  has  agreed to bear
certain  expenses of the Portfolio  pursuant to a voluntary  expense  limitation
currently in effect. This limitation may be terminated at any time. Commonwealth
is a wholly owned  subsidiary of Mentor,  which is a wholly owned  subsidiary of
Wheat First Butcher Singer,  Inc.  ("Wheat First Butcher  Singer").  Wheat First
Butcher  Singer,   through  other  subsidiaries,   also  engages  in  securities
brokerage,  investment banking, and related businesses.  Commonwealth  currently
has  assets  under  management  of  approximately  $4  billion,  and  serves  as
investment  adviser  to Cash  Resource  Trust,  an  open-end  series  investment
company,  Mentor Balanced  Portfolio,  Mentor Quality Income  Portfolio,  Mentor
Short-Duration  Income  Portfolio,  SNAP Fund,  and America's Utility Fund,
Inc., each of which is an open-end investment  company,  and Mentor  Income
Fund,  Inc.,  a  closed-end  investment company.
   
     Subject to the general oversight of the Trustees, Commonwealth, as
investment adviser, manages the Portfolio in accordance with the stated policies
of the Portfolio. All investment decisions for the Portfolio are made by an
investment committee at Commonwealth which is made up of investment
professionals of that firm.
    

     Commonwealth  makes  investment  decisions for the Portfolio and places the
purchase  and  sale  orders  for  the  Portfolio's  portfolio  transactions.  In
selecting  broker-dealers,  Commonwealth  may consider  research  and  brokerage
services furnished to it and its affiliates. Subject to seeking the best overall
terms available,

                                      -6-


<PAGE>



Commonwealth may consider sales of shares of the Portfolio (and, if permitted by
law, of other  portfolios in the Mentor  family) as a factor in the selection of
broker-dealers to execute portfolio transactions for the Portfolio.

     PORTFOLIO TURNOVER.  The length of time the Portfolio has held a particular
security is not generally a consideration in investment  decisions.  A change in
the  securities  held by the  Portfolio is known as  "portfolio  turnover." As a
result of the Portfolio's  investment policies,  under certain market conditions
the Portfolio's  portfolio turnover rate may be higher than that of other mutual
funds.  Portfolio  turnover  generally  involves some expense to the  Portfolio,
including  brokerage  commissions or dealer mark-ups and other transaction costs
on  the  sale  of  securities  and  reinvestment  in  other   securities.   Such
transactions may result in realization of taxable capital gains.  The portfolio
turnover rate for the fiscal period ended October 31,  1995  for the  Portfolio 
is  contained  in the  section  "Financial Highlights."

HOW THE PORTFOLIO VALUES ITS SHARES

     The Portfolio  calculates the net asset value of its shares by dividing the
total  value of its  assets,  less  liabilities,  by the  number  of its  shares
outstanding.  Shares are  valued as of the close of  regular  trading on the New
York Stock  Exchange  each day the Exchange is open.  Portfolio  securities  for
which  market  quotations  are  readily  available  are stated at market  value.
Short-term  investments  that  will  mature  in 60 days or less  are  stated  at
amortized  cost,  which has been determined to approximate the fair market value
of such  investments.  All other  securities and assets are valued at their fair
values.

HOW DISTRIBUTIONS ARE MADE

     The  Portfolio  distributes  net  investment  income  quarterly and any net
realized capital gains at least annually.  Distributions  from capital gains are
made after  applying  any  available  capital  loss  carryovers.  All  Portfolio
distributions  will be  invested  in  additional  Portfolio  shares,  unless the
shareholder instructs the Portfolio otherwise.

TAXES

     The Portfolio  intends to qualify as a "regulated  investment  company" for
federal  income  tax  purposes  and to meet  all  other  requirements  that  are
necessary  for it to be  relieved  of  federal  taxes  on  income  and  gains it
distributes to shareholders.  The Portfolio will distribute substantially all of
its net investment income and capital gain net income on a current basis.

     The following is intended  principally for shareholders  subject to federal
income taxation:

     All Portfolio distributions,  other than exempt-interest dividends, will be
taxable to shareholders as ordinary income, except that any distributions of net
capital gain will be taxed as long-term  capital gain,  regardless of how long a
shareholder has held the shares  (although the loss on a sale of shares held for
six months or less will be treated as  long-term  capital  loss to the extent of
any  capital  gain   distribution   received  with  respect  to  those  shares).
Distributions  will be taxable as described above whether received in cash or in
shares through the reinvestment of  distributions.  Early in each year the Trust
will notify  shareholders of the amount and tax status of distributions  paid by
the Portfolio for the preceding  year. In buying or selling  securities  for the
Portfolio,  Commonwealth  will not  normally  take into  account  the effect any
purchase or sale of securities will have on the tax positions of the Portfolio's
shareholders.

     The foregoing is a summary of certain federal income tax consequences of
investing in the Portfolio. Dividends and distributions also may be subject to
state and local taxes.  Shareholders are urged to consult their tax advisers
regarding specific questions as to federal, state, or local taxes.  Non-U.S.
investors should consult

                                      -7-


<PAGE>



their tax advisers concerning the tax consequences of ownership of shares of the
Portfolio,  including the possibility that distributions may be subject to a 30%
United  States  withholding  tax (or a reduced rate of  withholding  provided by
treaty).

PURCHASE OF SHARES

     Shares of the  Portfolio  are sold at the net asset  value next  determined
after a purchase  order is received by the Portfolio.  Purchase  orders that are
received  prior to the close of  trading  on the New York  Stock  Exchange  on a
particular  day are priced  according to the net asset value  determined on that
day.

     Mentor Distributors, Inc. ("Mentor Distributors"), 901 East Byrd Street,
Richmond, Virginia 23219, serves as distributor of the Portfolio's shares.
Mentor Distributors is not obligated to sell any specific amount of shares of
the Portfolio.

     An  investor  may make an initial  purchase of shares of the  Portfolio  by
submitting a completed Trust  application  along with a purchase  order,  and by
making  payment  to Mentor  Distributors.  Investors  will be  required  to make
minimum initial  investments of $500,000 in the Portfolio and minimum subsequent
investments of $25,000.  Investments made through advisory  accounts  maintained
with investment  advisers  registered under the Investment  Advisers Act of 1940
(including  "wrap"  accounts)  are  not  subject  to  these  minimum  investment
requirements. The Portfolio reserves the right at any time to change the initial
and subsequent investment minimums required of investors.

     Shares  of  the  Portfolio  may  be  purchased  by (i)  paying  cash,  (ii)
exchanging securities acceptable to Commonwealth, or (iii) a combination of such
securities  and cash.  Purchase  of  shares of the  Portfolio  in  exchange  for
securities is subject in each case to the determination by Commonwealth that the
securities  to be  exchanged  are  acceptable  for  purchase  by the  Portfolio.
Securities  accepted by  Commonwealth  in exchange for Portfolio  shares will be
valued  in the  same  manner  as the  Portfolio's  assets  as of the time of the
Portfolio's next  determination  of net asset value after such  acceptance.  All
dividends  and  subscription  or other rights which are  reflected in the market
price of accepted securities at the time of valuation become the property of the
Portfolio  and must be delivered to the  Portfolio  upon receipt by the investor
from the  issuer.  A gain or loss  for  federal  income  tax  purposes  would be
realized  upon the  exchange  by an investor  that is subject to federal  income
taxation,  depending upon the investor's  basis in the  securities  tendered.  A
shareholder who wishes to purchase shares by exchanging securities should obtain
instructions by calling Mentor Distributors at 1-800-869-6042.

     In all cases  Commonwealth  or Mentor  Distributors  reserves  the right to
reject any particular investment.

REDEMPTION OF SHARES

     A shareholder  may redeem all or any portion of its shares in the Portfolio
at any  time  upon  request,  by  following  the  procedures  set  forth  below.
Redemptions  will be effected at the net asset value per share of the  Portfolio
next determined after the receipt by the Portfolio of redemption instructions in
"good order" as described below.  Shares may be redeemed by submitting a written
request for redemption to Mentor Distributors,  or to the Trust at the following
address:

                           Mentor Institutional Trust
                                 P.O. Box 1357
                         Richmond, Virginia 23286-0109

     Upon  receipt of a request in "good  order," the Trust will  determine  the
amount of the net asset value of the redeemed  shares,  based upon the net asset
value of the Portfolio next  determined  after the  redemption  request has been
received.  A check for the proceeds will normally be mailed on the next business
day.

                                      -8-


<PAGE>



     If shares of the Portfolio to be redeemed  represent an investment  made by
check,  the Trust reserves the right not to transmit the redemption  proceeds to
the shareholder until the check has been collected, which may take up to 15 days
after the purchase date.

     A redemption  request will be  considered to have been made in "good order"
if the following conditions are satisfied:

              (1)   the request is in writing, states the number of shares to be
                    redeemed, and identifies the shareholder's Portfolio account
                    number;

              (2)   the request is signed by each registered owner exactly as
                    the shares are registered; and

              (3)   if the  shares to be  redeemed  were  issued in  certificate
                    form,  the  certificates  are  endorsed for transfer (or are
                    accompanied  by an endorsed  stock power) and  accompany the
                    redemption request.

     The  Portfolio  reserves  the  right to  require  signature  guarantees.  A
guarantor of a signature must be an eligible guarantor  institution,  which term
includes most banks and trust companies,  savings  associations,  credit unions,
and securities  brokers or dealers.  The purpose of a signature  guarantee is to
protect Portfolio shareholders against the possibility of fraud.

     Mentor  Distributors  may facilitate any  redemption  request.  There is no
extra charge for this service.

     OTHER INFORMATION CONCERNING REDEMPTION.  Under unusual circumstances,  the
Portfolio may suspend repurchases, or postpone payment for more than seven days,
as permitted by federal securities laws. In addition, the Portfolio reserves the
right, if conditions  exist which make cash payments  undesirable,  to honor any
request  for  redemption  by making  payment  in whole or in part by  securities
valued in the same way as they would be valued for  purposes  of  computing  the
Portfolio's  per share net asset  value.  If  payment is made in  securities,  a
shareholder may incur  brokerage  expenses in converting  those  securities into
cash.

     EXCHANGE PRIVILEGE. Shareholders may exchange their shares in the Portfolio
for shares of certain other Portfolios  comprising the Trust at their respective
net asset values beginning 15 days after purchase.  Contact Mentor  Distributors
for a prospectus of any of those Portfolios. Shares of certain of the Portfolios
are not available in all states. To exchange shares, simply complete an exchange
authorization form and send it to Mentor  Distributors.  Exchange  authorization
forms  are  available  from the Trust and from  Mentor  Distributors.  The Trust
reserves  the right to change or suspend  the  exchange  privilege  at any time.
Shareholders  would be notified  before any such change or  suspension.  Consult
Mentor Distributors before requesting an exchange.

MENTOR INSTITUTIONAL TRUST

     Mentor  Institutional Trust is a Massachusetts  business trust organized on
February  8,  1994  as IMG  Institutional  Trust.  A copy of the  Agreement  and
Declaration of Trust,  which is governed by  Massachusetts  law, is on file with
the Secretary of State of The Commonwealth of Massachusetts.
   

     The Trust is an open-end series management investment company, with an
unlimited number of authorized shares of beneficial interest.  Shares of the
Trust may, without shareholder  approval, be divided into two or more series of
shares representing separate investment portfolios. Any such series of shares
may be further divided without shareholder  approval into two or more classes of
shares having such preferences and special or relative rights and privileges as
the Trustees determine.  The Trust's  shares are  currently  divided into five
series, one representing the Portfolio, the others representing other Portfolios
with varying investment  objectives and policies.  Each share has one vote, with
fractional shares voting proportionally. Shares of each

                                      -9-


<PAGE>



class will vote  together  as a single  class  except  when  required  by law or
determined by the Trustees. Shares of the Portfolio are freely transferable, are
entitled to dividends as declared by the Trustees,  and, if the  Portfolio  were
liquidated, would receive the net assets of the Portfolio. The Trust may suspend
the sale of shares at any time and may  refuse  any  order to  purchase  shares.
Although the Trust and the Portfolio are not required to hold annual meetings of
its  shareholders, shareholders have the right to call a meeting to elect or
remove Trustees, or to take other actions as provided in the Agreement and
Declaration of Trust.
    

     In the interest of economy and  convenience,  the Portfolio  will not issue
certificates for its shares except at the shareholder's request.

CUSTODIAN AND TRANSFER AND DIVIDEND AGENT
   
     Investors Fiduciary Trust Company, 127 West 10th Street, Kansas City,
Missouri 64105, serves as the Portfolio's custodian.  State Street Bank and
Trust Company, c/o Boston Financial Data Services, Inc., 2 Heritage Drive,
North Quincy, Massachusetts, 02171, serves as the Portfolio's transfer and
dividend agent.
    

PERFORMANCE INFORMATION

   

     Yield  and  total  return  data  may  from  time  to time  be  included  in
advertisements  about the Portfolio.  The  Portfolio's  "yield" is calculated by
dividing the  Portfolio's  annualized net  investment  income per share during a
recent  30-day  period  by its net asset  value on the last day of that  period.
"Total  return" for the life of the Portfolio  through the most recent  calendar
quarter  represents  the average annual compound rate of return on an investment
of $1,000 in the Portfolio  over the  period.  The  Portfolio's  performance
may be  compared to various indices. See the Statement of Additional
Information. Information may be presented in  advertisements  about the

     All data is based on the Portfolio's  past investment  results and does not
predict future performance. Investment performance, which will vary, is based on
many factors,  including market  conditions,  the composition of the Portfolio's
investments, and the Portfolio's operating expenses. Investment performance also
often reflects the risks associated with the Portfolio's  investment  objectives
and policies.  These factors should be considered when comparing the Portfolio's
investment results to those of other mutual funds and other investment vehicles.

EXPENSE SUMMARY

         Expenses  are one of several  factors to consider  when  investing in a
Portfolio.  The following  table  summarizes an investor's  maximum  transaction
costs from investing in the Portfolio and expenses  incurred for the past fiscal
year. The Example shows the cumulative  expenses  attributable to a hypothetical
$1,000 investment in the Portfolio over specified periods.

        SHAREHOLDER TRANSACTION EXPENSES:
        Maximum Sales Load Imposed on Purchases                        None
        Maximum Sales Load Imposed on Reinvested Dividends             None
        Deferred Sales Load                                            None
        Redemption Fees                                                None
        Exchange Fee                                                   None

               ANNUAL FUND OPERATING EXPENSES:
               (as a percentage of average net assets)
                  Management Fees                                    0.00%
                  12b-1 Fees                                         0.00%
                  Other Expenses (after voluntary
                    expense limitation)*                             0.04%
                    Total Fund Operating Expenses*                   0.04%
- --------------------
   
     *Other Expenses reflect a voluntary expense limitation currently in effect.
In the  absence  of the  expense  limitation,  Other  Expenses  and  Total  Fund
Operating Expenses would have been 0.18%.
    
EXAMPLE

     An  investment  of  $1,000  in the  Portfolio  would  incur  the  following
expenses, assuming 5% annual return and redemption at the end of each period:
   
                          1 year                    $1
                          3 years                   $2
                          5 years                   $3
                         10 years                   $6
    
     This  information is provided to help investors  understand the expenses of
investing in the Portfolio and an  investor's  share of the estimated  operating
expenses of the Portfolio. The Example should not be considered a representation
of future performance; actual expenses may be more or less than those shown.

INVESTMENT OBJECTIVE AND POLICIES
   
     MENTOR CASH MANAGEMENT  PORTFOLIO'S INVESTMENT OBJECTIVE IS TO SEEK AS HIGH
A  RATE  OF   CURRENT   INCOME  AS   COMMONWEALTH   INVESTMENT   COUNSEL,   INC.
("COMMONWEALTH")  BELIEVES  IS  CONSISTENT  WITH  PRESERVATION  OF  CAPITAL  AND
MAINTENANCE OF LIQUIDITY.  The Portfolio will invest in high-quality  short-term
instruments including U.S. Government  securities,  banker's acceptances,  prime
commercial  paper,  fixed-income  securities of  corporations  and other private
issuers,  and money market  instruments.  There can, of course,  be no assurance
that the Portfolio  will achieve its  investment  objective.  The Portfolio is a
series of Mentor Institutional Trust and is an open-end, diversified,
management investment company.
    
     The  Portfolio  will  invest  in a  portfolio  of  high-quality  short-term
instruments consisting of any or all of the following:

(BULLET)    U.S. GOVERNMENT SECURITIES: securities issued or guaranteed as to
            principal or interest by the U.S. Government or by any of its
            agencies or instrumentalities.


                                      -3-


<PAGE>



(BULLET)    BANKERS'  ACCEPTANCES:  negotiable drafts or bills of exchange,
            which have been  "accepted"  by a  domestic  bank (or a  foreign
            bank  with an agency domiciled  in the United  States),  meaning,
            in effect,  that the bank has unconditionally agreed to pay the face
            value of the instrument on maturity.

(BULLET)    PRIME COMMERCIAL PAPER: high-quality, short-term obligations issued
            by banks, corporations, and other issuers organized under the laws
            of a jurisdiction within the United States.

(BULLET)    OTHER SHORT-TERM OBLIGATIONS: high-quality, short-term obligations
            of corporate issuers.

(BULLET)    REPURCHASE AGREEMENTS:  with respect to U.S. Government or agency
            securities.

   
     The  Portfolio  will  invest only in U.S.  dollar-denominated  high-quality
securities and other U.S.  dollar-denominated  money market instruments  meeting
credit  criteria  which  the  Trustees  of the Trust believe  present  minimal
credit  risk. "High-quality   securities"  are  (i)  commercial   paper  or
other  short-term obligations  rated  A-1 by  Standard  & Poor's  Corporation
and P-1 by  Moody's Investors  Service,  Inc.,  and (ii)  obligations  rated AAA
or AA by Standard & Poor's and Aaa or Aa by Moody's at the time of  investment.
The Portfolio  will not invest  more than 5%  (determined  at the time of
investment)  of its total assets in securities  rated below A-1 or P-1 (or
securities  not so rated whose issuer does not have  outstanding  short-term
debt  obligations,  of comparable priority  and  security,  rated  A-1 or P-1).
The  Portfolio  will  maintain  a dollar-weighted  average  maturity  of 90 days
or less and will  not  invest  in securities with remaining maturities of more
than thirteen months. The Portfolio may invest in variable or floating-rate
securities which bear interest at rates subject to  periodic  adjustment  or
which  provide  for  periodic  recovery  of principal on demand. Under certain
conditions, these securities may be deemed to have remaining  maturities  equal
to the time remaining  until the next interest adjustment date or the date on
which  principal can be recovered on demand.  The Portfolio will not purchase
securities of any issuer if, immediately thereafter, more than 5% of its total
assets would be invested in securities of that issuer, nor will the Portfolio
make an investment in commercial  paper if,  immediately thereafter,  more than
35% of its total assets  would be invested in  commercial paper.  The Portfolio
follows  investment  and valuation  policies  designed to maintain  a stable
net asset  value of $1.00 per  share,  although  there is no assurance that
these policies will be successful.
    
     Considerations  of  liquidity  and  preservation  of capital  mean that the
Portfolio  may not  necessarily  invest in money market  instruments  paying the
highest  available  yield at a particular  time.  Consistent with its investment
objective,  the Portfolio will attempt to maximize  yields by portfolio  trading
and by  buying  and  selling  portfolio  investments  in  anticipation  of or in
response  to changing  economic  and money  market  conditions  and trends.  The
Portfolio may also invest to take advantage of what Commonwealth  believes to be
temporary  disparities in yields of different segments of the high-quality money
market or among  particular  instruments  within the same segment of the market.
These  policies,  as  well  as the  relatively  short  maturity  of  obligations
purchased by the  Portfolio,  may result in frequent  changes in the  securities
held by the Portfolio.  The Portfolio will not usually pay brokerage commissions
in connection with the purchase or sale of portfolio securities.

     The Portfolio's  securities will be affected by general changes in interest
rates resulting in increases or decreases in the values of the obligations  held
by the  Portfolio.  The value of the  Portfolio's  securities can be expected to
vary  inversely  to  changes  in  prevailing  interest  rates.   Withdrawals  by
shareholders could require the sale of portfolio investments at a time when such
a sale might not otherwise be desirable.


   
     CONCENTRATION. The Portfolio may invest without limit in obligations of
domestic branches of U.S. banks and U.S. branches of foreign banks (if it can be
demonstrated that they are subject to the same regulations as U.S. banks). At
times when the Portfolio has concentrated its investments in bank obligations,
the value of its portfolio securities may be especially affected by factors
pertaining to the issuers of such obligations.
    

OTHER INVESTMENT PRACTICES AND RISKS

     The Portfolio may engage in the other investment practices described below.
See the Statement of Additional  Information for a more detailed  description of
these practices and certain risks they may involve.

     REPURCHASE  AGREEMENTS.   Under  a  repurchase  agreement,   the  Portfolio
purchases a debt instrument for a relatively short period (usually not more than
one week), which the seller agrees to repurchase at a fixed time and

                                      -4-


<PAGE>



price, representing the Portfolio's cost plus interest. The Portfolio will enter
into  repurchase  agreements  only with  commercial  banks  and with  registered
broker-dealers  who are  members of a  national  securities  exchange  or market
makers in government securities,  and only if the debt instrument subject to the
repurchase agreement is a U.S. Government security.  Although  Commonwealth will
monitor  repurchase  agreement  transactions  to ensure  that they will be fully
collateralized  at all times,  the  Portfolio  bears a risk of loss if the other
party  defaults on its obligation and the Portfolio is delayed or prevented from
exercising  its rights to dispose of the  collateral.  If the other party should
become involved in bankruptcy or insolvency proceedings, it is possible that the
Portfolio may be treated as an unsecured  creditor and be required to return the
underlying collateral to the other party's estate.

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


     As a matter  of  policy,  the  Trustees  will  not  materially  change  the
Portfolio's investment objective without shareholder approval.  (Any such change
could,  of course,  result in a change in the nature of the  securities in which
the  Portfolio  may  invest  and the  risks  involved  in an  investment  in the
Portfolio.)

MANAGEMENT OF THE PORTFOLIO
   
     The Trustees of the Trust are  responsible  for  generally  overseeing  the
conduct of the Trust's business.  COMMONWEALTH INVESTMENT COUNSEL, INC., located
at 901 East Byrd Street, Richmond, Virginia 23219, acts as investment adviser to
the  Portfolio  pursuant  to  a  Management   Contract  between  the  Trust  and
Commonwealth.  MENTOR INVESTMENT GROUP, INC.  ("Mentor") serves as administrator
to the Portfolio. Neither Commonwealth nor Mentor receives compensation from the
Portfolio  for the  performance  of such  services.  Mentor  has  agreed to bear
certain  expenses of the Portfolio  pursuant to a voluntary  expense  limitation
currently in effect. This limitation may be terminated at any time. Commonwealth
is a wholly owned  subsidiary of Mentor,  which is a wholly owned  subsidiary of
Wheat First Butcher Singer,  Inc.  ("Wheat First Butcher  Singer").  Wheat First
Butcher  Singer,   through  other  subsidiaries,   also  engages  in  securities
brokerage,  investment banking, and related businesses.  Commonwealth  currently
has  assets  under  management  of  approximately  $4  billion,  and  serves  as
investment  adviser  to Cash  Resource  Trust,  an  open-end  series  investment
company,  Mentor Balanced  Portfolio,  Mentor Quality Income  Portfolio,  Mentor
Short-Duration  Income  Portfolio,  SNAP Fund,  and America's Utility, Inc.,
each of which is an open-end investment  company,  and Mentor  Income Fund,
Inc.,  a  closed-end  investment company.
    

   
     Subject to the general oversight of the Trustees, Commonwealth, as
investment adviser, manages the Portfolio in accordance with the stated policies
of the Portfolio.
    


     Commonwealth  makes  investment  decisions for the Portfolio and places the
purchase  and  sale  orders  for  the  Portfolio's  portfolio  transactions.  In
selecting  broker-dealers,  Commonwealth  may consider  research  and  brokerage
services furnished to it and its affiliates. Subject to seeking the best overall
terms  available,  Commonwealth  may consider  sales of shares of the  Portfolio
(and, if permitted by law, of other portfolios in the Mentor family) as a factor
in the selection of  broker-dealers  to execute  portfolio  transactions for the
Portfolio.

HOW THE PORTFOLIO VALUES ITS SHARES AND DISTRIBUTES INCOME

     The Portfolio  values its shares twice each day the New York Stock Exchange
is open,  once at 12:00  noon and again at the close of  regular  trading on the
Exchange. The Portfolio's  investments are valued at amortized cost according to
Securities  and Exchange  Commission  Rule 2a-7. The Portfolio will not normally
have  unrealized  gains or losses so long as it values  its  investments  by the
amortized cost method.


                                      -5-


<PAGE>



     The Portfolio  determines its net income as of the close of regular trading
on the  Exchange  each day the  Exchange  is  open.  Each  determination  of the
Portfolio's  net income  includes  (i) all accrued  interest in the  Portfolio's
investments,  (ii) plus or minus all realized and unrealized gains and losses on
the Portfolio's investments, (iii) less all accrued expenses of the Portfolio.

     The Portfolio  declares all of its net interest income as a distribution on
each day the Exchange is open for  business,  as a dividend to  shareholders  of
record  immediately  prior to the  close of  regular  trading  on the  Exchange.
Shareholders  who purchase  shares of the  Portfolio as of 12:00 noon on any day
will receive the dividend  declared by the Portfolio for that day;  shareholders
who  purchase  shares after 12:00 noon will begin  earning  dividends on the day
after the  Portfolio  accepts  their  order.  The  Portfolio's  net  income  for
Saturdays,  Sundays,  and  holidays is  declared as a dividend on the  preceding
business day. Dividends for the immediately  preceding month will be paid on the
last business day of each calendar month (or, if that day is not a business day,
on the next business day),  except that the Portfolio's  schedule for payment of
dividends  during  the  month of  December  may be  adjusted  to  assist  in tax
reporting and distribution requirements. A shareholder that withdraws the entire
balance of an account  at any time  during the month will be paid all  dividends
declared  through the date  immediately  prior to the withdrawal.  Since the net
income of the  Portfolio is declared as a dividend each day, the net asset value
per share of the Portfolio  normally remains at $1 per share  immediately  after
each determination and dividend declaration.

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

     All  Portfolio  distributions  will be  invested  in  additional  Portfolio
shares, unless the shareholder instructs the Portfolio otherwise.

TAXES

     The Portfolio  intends to qualify as a "regulated  investment  company" for
federal  income  tax  purposes  and to meet  all  other  requirements  that  are
necessary  for it to be  relieved  of  federal  taxes  on  income  and  gains it
distributes to shareholders.  The Portfolio will distribute substantially all of
its net investment income and capital gain net income on a current basis.

     The following is intended  principally for shareholders  subject to federal
income taxation:

     All Portfolio distributions,  other than exempt-interest dividends, will be
taxable to shareholders as ordinary income, except that any distributions of net
capital gain will be taxed as long-term  capital gain,  regardless of how long a
shareholder has held the shares  (although the loss on a sale of shares held for
six months or less will be treated as  long-term  capital  loss to the extent of
any  capital  gain   distribution   received  with  respect  to  those  shares).
Distributions  will be taxable as described above whether received in cash or in
shares through the reinvestment of  distributions.  Early in each year the Trust
will notify  shareholders of the amount and tax status of distributions  paid by
the Portfolio for the preceding  year. In buying or selling  securities  for the
Portfolio,  Commonwealth  will not  normally  take into  account  the effect any
purchase or sale of securities will have on the tax positions of the Portfolio's
shareholders.

     The foregoing is a summary of certain  federal income tax  consequences  of
investing in the Portfolio.  Dividends and distributions  also may be subject to
state and local  taxes.  Shareholders  are urged to consult  their tax  advisers
regarding  specific  questions as to federal,  state,  or local taxes.  Non-U.S.
investors  should consult their tax advisers  concerning the tax consequences of
ownership  of  shares  of  the  Portfolio,   including  the   possibility   that
distributions  may be  subject  to a 30%  United  States  withholding  tax (or a
reduced rate of withholding provided by treaty).

PURCHASE OF SHARES

                                      -6-


<PAGE>




     The Portfolio offers its shares continuously at a price of $1.00 per share.
Because the Portfolio seeks to be fully invested at all times,  investments must
be in Same Day Funds to be accepted.  "Same Day Funds" are funds credited by the
applicable  regional Federal Reserve Bank to the account of the Portfolio at its
designated bank.

     Mentor Distributors, Inc. ("Mentor Distributors"), 901 East Byrd Street,
Richmond, Virginia 23219, serves as distributor of the Portfolio's shares.
Mentor Distributors is not obligated to sell any specific amount of shares of
the Portfolio.

     An  investor  may make an initial  purchase of shares of the Portfolio  by
submitting a completed Trust  application  along with its purchase order, and by
making  payment  to Mentor  Distributors.  Investors  will be required  to make
minimum initial  investments of $500,000 in the Portfolio and minimum subsequent
investments of $25,000.  Investments made through advisory accounts  maintained
with investment  advisers  registered under the Investment Advisers Act of 1940
(including  "wrap"  accounts)  are  not  subject  to  these minimum  investment
requirements. The Portfolio reserves the right at any time to change the initial
and subsequent investment minimums required of investors.

     Shares  of  the  Portfolio  may  be  purchased  by (i)  paying  cash,  (ii)
exchanging securities acceptable to Commonwealth, or (iii) a combination of such
securities  and cash.  Purchase  of  shares of the  Portfolio  in  exchange  for
securities is subject in each case to the determination by Commonwealth that the
securities  to be  exchanged  are  acceptable  for  purchase  by the  Portfolio.
Securities  accepted by  Commonwealth  in exchange for Portfolio  shares will be
valued  in the  same  manner  as the  Portfolio's  assets  as of the time of the
Portfolio's next  determination  of net asset value after such  acceptance.  All
dividends  and  subscription  or other rights which are  reflected in the market
price of accepted securities at the time of valuation become the property of the
Portfolio  and must be delivered to the  Portfolio  upon receipt by the investor
from the  issuer.  A gain or loss  for  federal  income  tax  purposes  would be
realized  upon the  exchange  by an investor  that is subject to federal  income
taxation,  depending upon the investor's  basis in the  securities  tendered.  A
shareholder who wishes to purchase shares by exchanging securities should obtain
instructions by calling Mentor Distributors at 1-800-869-6042.

     In all cases  Commonwealth  or Mentor  Distributors  reserves  the right to
reject any particular investment.

REDEMPTION OF SHARES

     A shareholder  may redeem all or any portion of its shares in the Portfolio
at any  time  upon  request,  by  following  the  procedures  set  forth  below.
Redemptions  will be effected at the net asset value per share of the  Portfolio
next determined after the receipt by the Portfolio of redemption instructions in
"good  order" as described  below.  A check for the  proceeds  will  normally be
mailed on the next business day.  Shares may be redeemed by submitting a written
request for redemption to Mentor Distributors,  or to the Trust at the following
address:

                           Mentor Institutional Trust
                                 P.O. Box 1357
                         Richmond, Virginia 23286-0109

     If shares of the Portfolio to be redeemed  represent an investment  made by
check,  the Trust reserves the right not to transmit the redemption  proceeds to
the shareholder until the check has been collected, which may take up to 15 days
after the purchase date.

     A redemption  request will be  considered to have been made in "good order"
if the following conditions are satisfied:

              (1)   the request is in writing, states the number of shares to be
                    redeemed, and identifies the shareholder's Portfolio account
                    number;

                                      -7-


<PAGE>



              (2)   the request is signed by each registered owner exactly as
                    the shares are registered; and

              (3)   if the  shares to be  redeemed  were  issued in  certificate
                    form,  the  certificates  are  endorsed for transfer (or are
                    accompanied  by an endorsed  stock power) and  accompany the
                    redemption request.

     The  Portfolio  reserves  the  right to  require  signature  guarantees.  A
guarantor of a signature must be an eligible guarantor  institution,  which term
includes most banks and trust companies,  savings  associations,  credit unions,
and securities  brokers or dealers.  The purpose of a signature  guarantee is to
protect Portfolio shareholders against the possibility of fraud.

      Mentor  Distributors  may facilitate any redemption  request.  There is no
extra charge for this service.

     OTHER INFORMATION CONCERNING REDEMPTION.  Under unusual circumstances,  the
Portfolio may suspend repurchases, or postpone payment for more than seven days,
as permitted by federal securities laws. In addition, the Portfolio reserves the
right, if conditions  exist which make cash payments  undesirable,  to honor any
request  for  redemption  by making  payment  in whole or in part by  securities
valued in the same way as they would be valued for  purposes  of  computing  the
Portfolio's  per share net asset  value.  If  payment is made in  securities,  a
shareholder may incur  brokerage  expenses in converting  those  securities into
cash.

     EXCHANGE PRIVILEGE. Shareholders may exchange their shares in the Portfolio
for shares of certain other Portfolios  comprising the Trust at their respective
net asset values beginning 15 days after purchase.  Contact Mentor  Distributors
for a prospectus of any of those Portfolios. Shares of certain of the Portfolios
are not available in all states. To exchange shares, simply complete an exchange
authorization form and send it to Mentor  Distributors.  Exchange  authorization
forms  are  available  from the Trust and from  Mentor  Distributors.  The Trust
reserves  the right to change or suspend  the  exchange  privilege  at any time.
Shareholders  would be notified  before any such change or  suspension.  Consult
Mentor Distributors before requesting an exchange.

MENTOR INSTITUTIONAL TRUST

     Mentor  Institutional Trust is a Massachusetts  business trust organized on
February  8,  1994  as IMG  Institutional  Trust.  A copy of the  Agreement  and
Declaration of Trust,  which is governed by  Massachusetts  law, is on file with
the Secretary of State of The Commonwealth of Massachusetts.
   

     The Trust is an open-end series management investment company with an
unlimited number of authorized shares of beneficial interest.  Shares of the
Trust may, without shareholder  approval, be divided into two or more series of
shares representing separate investment portfolios. Any such series of shares
may be further divided without shareholder  approval into two or more classes of
shares having such  preferences and special or relative rights and privileges as
the Trustees  determine.  The Trust's  shares are  currently  divided into four
series, one representing the Portfolio, the others representing other Portfolios
with varying investment  objectives and policies.  Each share has one vote, with
fractional shares voting proportionally. Shares of each class will vote together
as a single class except when  required by law or  determined  by the  Trustees.
Shares of the  Portfolio are freely  transferable,  are entitled to dividends as
declared by the Trustees,  and, if the Portfolio were liquidated,  would receive
the net assets of the Portfolio. The Trust may suspend the sale of shares at any
time and may  refuse any order to  purchase  shares.  Although  the Trust and
the Portfolio are not required to hold  annual  meetings of its  shareholders,
shareholders  have the right to call a meeting to elect or remove Trustees, or
to take other actions as provided in the Agreement and Declaration of Trust.

    
     In the interest of economy and  convenience,  the Portfolio  will not issue
certificates for its shares except at the shareholder's request.

PERFORMANCE INFORMATION
   
     Yield  may  from  time  to time  be  included  in advertisements  about the
Portfolio.  The  Portfolio's  "yield" is calculated by determining the
percentage net change,  excluding capital changes,  in the value of an
investment  in one  share of the  Portfolio  over the  base  period,  and
multiplying the net change by 365/7 (or approximately 52 weeks). The Portfolio's
"effective  yield"  represents  a  compounding  of the  yield by adding 1 to the
number  representing the percentage change in value of the investment during the
base period,  raising that sum to a power equal to 365/7, and subtracting 1 from
the result. The Portfolio's  performance may be compared to various indices. See
the  Statement  of  Additional  Information.  Information  may be presented  in
advertisements  about the Portfolio  describing the background and professional
experience of the Portfolio's investment adviser or its investment personnel.
    

     All data is based on the Portfolio's  past investment  results and does not
predict future performance. Investment performance, which will vary, is based on
many factors,  including market  conditions,  the composition of the Portfolio's
investments, and the Portfolio's operating expenses. Investment performance also
often reflects the risks  associated with the Portfolio's  investment  objective
and policies.  These factors should be considered when comparing the Portfolio's
investment results to those of other mutual funds and other investment vehicles.

INVESTMENT OBJECTIVE AND POLICIES

     SNAP  FUND'S  INVESTMENT  OBJECTIVE  IS TO SEEK  AS HIGH A RATE OF  CURRENT
INCOME  AS  CIC  BELIEVES  IS  CONSISTENT  WITH   PRESERVATION  OF  CAPITAL  AND

will achieve its investment objective.  As a matter of policy, the Trustees will
not change the Fund's investment objective without shareholder approval.

     The Fund will invest in a portfolio of high-quality  short-term instruments
consisting of any or all of the following:

(BULLET)     U.S.Government securities: U.S.Treasury bills, notes, and bonds,
             and securities unconditionally guaranteed as to payment of
             principal and interest by the United States or any agency of the
             United States.

(BULLET)     Obligations of the  Commonwealth  of Virginia and of its local
             governments and  of  other  states:  high-quality  evidences  of
             indebtedness of  the Commonwealth  of  Virginia,  and  obligations
             of any county, city,  town, district, authority, or other public
             body of the Commonwealth. The Fund may also  invest  in
             high-quality-obligations  of any  other state  or of any county,
             city, town, or district located in any other state.

(BULLET)    Bankers'  acceptances:  negotiable drafts or bills of exchange,
            which have been  "accepted"  by  a  bank,  meaning,  in  effect,
            that  the  bank  has unconditionally agreed to pay the face value of
            the instrument on maturity. The Fund will only purchase bankers'
            acceptances issued by a bank organized in the U.S. or by a foreign
            bank with an agency domiciled in the U.S.

(BULLET)    Certificates of deposit and interest-bearing time deposits: of
            national banks or of banks chartered by the Commonwealth of Virginia
            or of banks chartered by other states and authorized to operate
            branches in the Commonwealth of Virginia (if such banks chartered by
            the Commonwealth or other states are under the supervision of the
            Commonwealth of Virginia and the deposits are secured as provided by
            the Virginia Security for Public Deposits Act). The amount of any
            deposit must be insured in its entirety by the Federal Deposit
            Insurance Corporation, except to the extent any such amount is
            collateralized by eligible collateral as prescribed by law.   Any
            time deposits made by the Fund must mature in seven days or less.

(BULLET)    Prime commercial paper: high-quality, short-term obligations issued
            by banks, corporations, and other issuers organized under the laws
            of the United States or of any state.

(BULLET)    Other short-term obligations: high-quality, short-term obligations
            of corporate issuers.

(BULLET)    Repurchase agreements: with respect to U.S. Government or agency
            securities. Under a repurchase  agreement,  the Fund purchases a
            U.S. Government security for a relatively  short period  (usually
            not more than one week) which the seller agrees to  repurchase  at a
            fixed time and price,  representing  the Fund's cost plus interest.
            The Fund will enter into  repurchase  agreements  only with
            commercial  banks  having  assets  of more than $1  billion  and
            with "primary dealers" in U.S. Government securities.  Although CIC
            will monitor repurchase  agreement  transactions  to  ensure  that
            they  will be  fully collateralized  at all  times,  the Fund  bears
            a risk of loss if the other party  defaults on its obligation and
            the Fund is delayed or prevented from exercising  its  rights to
            dispose of the  collateral.  If the other  party should

                                      -4-


<PAGE>



            become  involved in bankruptcy or  insolvency  proceedings,  it is
            possible that the Fund may be treated as an  unsecured  creditor
            and be required to return the  underlying  collateral  to the other
            party's estate.  The Fund requires  any  U.S.  Government
            securities  serving  as collateral  for a repurchase  agreement  to
            be  delivered  to the  Fund's custodian  (or any approved
            subcustodian).

   

     The  Fund  will  invest  only  in  U.S.   dollar-denominated   high-quality
securities and other U.S.  dollar-denominated  money market instruments  meeting
credit  criteria  which  the  Trustees  of the Trust believe  present  minimal
credit  risk. "High-quality   securities"  are  (i)  commercial   paper  or
other  short-term obligations  rated  A-1 by  Standard  & Poor's  Corporation
and P-1 by  Moody's Investors Service,  Inc., and (ii) other obligations rated
AAA or AA by Standard & Poor's and Aaa or Aa by Moody's at the time of
investment.  The Fund will not purchase  securities of any issuer (other than
U.S.  Government  securities) if, immediately  thereafter,  more  than 5% of the
Fund's  total  assets  would  be invested in securities  of that issuer (or 1%
of the Fund's total assets,  or $1 million,  whichever is greater,  if the
securities  of such issuer owned by the Fund are not rated in the highest
rating  category by a  nationally  recognized statistical  rating
organization),  nor  will the Fund  make an  investment  in commercial paper if,
immediately  thereafter,  more than 35% of its total assets would be invested in
commercial paper.
    

       The Fund follows investment and valuation policies designed to maintain a
stable net asset value of $1.00 per share,  although  there is no assurance that
these  policies will be  successful.  The Fund will  maintain a  dollar-weighted
average  maturity  of 90 days or less and will not  invest  in  securities  with
remaining  maturities of more than one year.  The Fund may invest in variable or
floating-rate  securities  which bear  interest  at rates  subject  to  periodic
adjustment or which provide for periodic recovery of principal on demand.  Under
certain conditions,  these securities may be deemed to have remaining maturities
equal to the time remaining until the next interest  adjustment date or the date
on which principal can be recovered on demand.

     Considerations  of liquidity and preservation of capital mean that the Fund
may not  necessarily  invest in money  market  instruments  paying  the  highest
available yield at a particular time.  Consistent with its investment objective,
the Fund will attempt to maximize yields by portfolio  trading and by buying and
selling  portfolio  investments  in  anticipation  of or in response to changing
economic and money  market  conditions  and trends.  The Fund may also invest to
take  advantage of what CIC believes to be  temporary  disparities  in yields of
different  segments  of  the  high-quality  money  market  or  among  particular
instruments  within the same segment of the market.  These policies,  as well as
the relatively  short maturity of obligations  purchased by the Fund, may result
in  frequent  changes in the Fund's  portfolio.  The Fund will not  usually  pay
brokerage  commissions  in  connection  with the  purchase or sale of  portfolio
securities.

     The Fund's  portfolio will be affected by general changes in interest rates
resulting in increases or decreases in the values of the obligations held by the
Fund.  The value of the  securities  in the Fund's  portfolio can be expected to
vary  inversely to the changes in  prevailing  interest  rates.  Withdrawals  by
shareholders could require the sale of portfolio investments at a time when such
a sale might not otherwise be desirable.

     The Fund will not lend money,  other than by investment in the  instruments
described above and through entry into repurchase agreements, nor will it borrow
money or pledge,  hypothecate,  or mortgage its assets. The Fund will not invest
in  securities  of an  issuer  if any  employee  of the Fund or CIC (or,  to the
knowledge  of the Fund or CIC, any  affiliated  person of the Fund or CIC) is an
officer  or  director  of that  issuer  or holds 10% of the  outstanding  voting
securities of that issuer,  unless the investment is approved or ratified by the
Trustees.

     The Fund will not be responsible  for  determining  whether income or gains
from  any  investment  by the  Fund  will  be  excludable  from  the  income  of
participants in the SNAP Program for tax purposes,  or will otherwise be subject
to or exempt from taxation under federal or state law or be subject to rebate by
participants under federal law.

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

     All  percentage  limitations  on  investments  will  apply  at the  time of
investment and shall not be considered  violated  unless an excess or deficiency
occurs or exists immediately after and as a result of such investment.

MANAGEMENT OF THE FUND
   
     The Trustees of Mentor  Institutional  Trust are  responsible for generally
overseeing the conduct of the Trust's business. COMMONWEALTH INVESTMENT COUNSEL,
INC.,  located  at 901 East  Byrd  Street,  Richmond,  Virginia  23219,  acts as
investment  adviser to the Fund  pursuant to a Management  Contract  between the
Fund  and CIC.  Subject  to the  general  oversight  of the  Trustees,  CIC,  as
investment  adviser,  manages the Fund's portfolio in accordance with the stated
policies of the Fund. CIC makes investment decisions for the Fund and places the
purchase and sale orders for the Fund's portfolio transactions.  As compensation
for CIC's services under the Management  Contract,  the Fund pays a fee, accrued
daily and paid  monthly,  at the following  annual rate:  .09% of the first $500
million of average net assets;  .08% of the next $250 million;  .07% of the next
$250 million;  .06% of the next $250 million;  and .05% of any amount over $1.25
billion.  CIC is a wholly owned  subsidiary of Mentor  Investment  Group,  Inc.,
which is a wholly owned  subsidiary of Wheat First Butcher Singer,  Inc. ("Wheat
First Butcher Singer").  Wheat First Butcher Singer, through other subsidiaries,
also  engages  in  securities   brokerage,   investment  banking,   and  related

     Subject to the  general  oversight  of the  Trustees,  CIC,  as  investment
adviser, manages the Fund in accordance with its stated investment objective and
policies. A team of investment professionals manages the Fund for CIC.

HOW THE FUND VALUES ITS SHARES

     The Fund values its shares twice each day,  once at 12:00 noon and again at
the  close  of  regular  trading  on the New York  Stock  Exchange.  The  Fund's
investments  are valued at amortized  cost  according to Securities and Exchange
Commission Rule 2a-7. The Fund will not normally have unrealized gains or losses
so long as it values its investments by the amortized cost method.

HOW DISTRIBUTIONS ARE MADE

     The Fund declares all of its net interest  income as a distribution on each
day the New  York  Stock  Exchange  is  open  for  business,  as a  dividend  to
shareholders of record  immediately prior to the close of regular trading on the
Exchange.  Shareholders  who purchase shares of the Fund as of 12:00 noon on any
day will  receive the dividend  declared by the Fund for that day;  shareholders
who  purchase  shares after 12:00 noon will begin  earning  dividends on the day
after the Fund  accepts  their  order.  The Fund's  net  income  for  Saturdays,
Sundays,  and holidays is declared as a dividend on the preceding  business day.
Dividends  for any month will be paid on the last day of that month (or, if that
day is not a business  day,  on the  preceding  business  day),  except that the
Fund's  schedule  for payment of  dividends  during the month of December may be
adjusted to assist in the Fund's tax  reporting and  distribution  requirements.
All  distributions  will be  reinvested  automatically  in Fund shares as of the
payment date, unless the shareholder  instructs the Fund to pay distributions to
it in cash.  Since the net income of the Fund is declared as dividend  each time
it is determined,  the net asset value per share of the Fund normally remains at
$1 per share immediately after each determination and dividend declaration.

     The Fund intends to qualify as a "regulated investment company" for federal
income tax  purposes  to be  relieved  of  federal  taxes on income and gains it
distributes to shareholders.  The Fund will distribute  substantially all of its
net  investment  income  and  capital  gain  net  income  on  a  current  basis.
Shareholders  are  urged  to  consult  their  tax  advisers  regarding  specific
questions as to federal, state, or local taxes.

HOW TO PARTICIPATE IN THE FUND

     Shares of the Fund are currently  being offered only to participants in the
Commonwealth  of Virginia  State  Non-Arbitrage  Program  (the "SNAP  Program").
Participants  in the SNAP Program  wishing to purchase shares of the Fund should
consult the Information Statement of the SNAP Program, as it may be amended from
time to time (the "Information  Statement"),  or should contact the SNAP Program
directly,  for  information as to the procedures  they should follow in order to
purchase shares of the Fund through the Program.

                                      -7-


<PAGE>



     All Fund shares owned  beneficially by participants in the SNAP Program are
owned of  record  by the  Treasury  Board,  an  agency  of the  Commonwealth  of
Virginia,  for the benefit of  participants.  Because the Treasury Board will be
the record  owner of all shares of the Fund owned  beneficially  by SNAP Program
participants,  a Program  participant should follow the procedures  described in
the Information Statement of the SNAP Program to ensure that all instructions as
to any investment by it in the Fund -- including instructions as to the purchase
or sale of shares of the Fund -- are timely carried out by the SNAP Program.

     PURCHASE ORDERS; PURCHASE PRICE. The Fund offers its shares continuously at
a price of $1.00 per share.  Shares of the Fund are sold at the net asset  value
next  determined  after a purchase  order is  received by the Fund from the SNAP
Program.  The Fund  determines its net asset value at 12:00 noon on each day the
New York Stock  Exchange is open.  Purchase  orders that are  received  prior to
12:00 noon on a  particular  day are  priced  according  to the net asset  value
determined  at that time,  and the shares  purchased  at that time will earn the
dividend  declared for that day.  Purchase  orders that are received after 12:00
noon are priced based on the net asset value  determined  as of the close of the
New York Stock  Exchange on that day,  and begin to earn  dividends  on the next
day.

     Because the Fund seeks to be fully invested  at all times,  investments
must be in Same Day Funds to be  accepted. "Same Day Funds" are funds credited
by the applicable  regional  Federal Reserve Bank to the account of the Fund at
Central Fidelity National Bank. A participant in the SNAP  Program  wishing  to
invest in the Fund must  ensure  that  Central Fidelity  National Bank, as
Depository  for the SNAP Program,  receives Same Day Funds at or prior to the
time the  participant  wishes  to  invest  in the Fund. Consult the Information
Statement or contact the investment manager for the SNAP Program directly for
information.

HOW TO REDEEM SHARES

     Shares  of the Fund  may be  redeemed  on any day  when the New York  Stock
Exchange is open.  Redemptions will be effected at the net asset value per share
of the Fund next  determined  after  receipt of the  redemption  request in good
order.  Shares  redeemed  at the Fund's  12:00 noon price do not earn the income
dividend  declared on the day of  redemption.  Participants  should  consult the
Information  Statement or contact the SNAP  Program  directly to ensure that all
necessary steps are taken to effect the timely redemption of their shares.

     REDEMPTIONS BY CHECK. SNAP Program participants may elect to have a special
checking account with Central Fidelity National Bank. Checks may be drawn on the
account for any amount.  Upon  receipt of a completed  signature  card,  Central
Fidelity  National  Bank will  provide the  participant  with a supply of checks
drawn on the account. Additional supplies of checks are available, upon request.
When a check is presented to Central Fidelity  National Bank, a number of shares
in the Fund owned  beneficially by the checkwriter  will be redeemed in order to
pay the full amount of the check.

                                      -8-


<PAGE>



     Redemption by check is not  appropriate  for a complete  liquidation  of an
account.  If the amount of a  redemption  check is greater than the value of the
shares owned beneficially by the checkwriter,  the check will be returned to the
depositor due to an insufficient account balance. The checkwriting privilege may
be suspended at any time. Consult the Information  Statement or contact the SNAP
Program for additional information.

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

     The Fund will normally redeem shares for cash;  however,  the Fund reserves
the right to pay the  redemption  price wholly or partly in kind if the Trustees
determine it to be advisable in the interest of the remaining  shareholders.  If
portfolio  securities  are  distributed in lieu of cash,  the  shareholder  will
normally incur brokerage  commissions  upon  subsequent  disposition of any such
securities.

     If shares of the Fund to be redeemed represent an investment made by check,
the Fund  reserves  the right not to  transmit  the  redemption  proceeds to the
shareholder  until  the check  has been  collected  which may take up to 15 days
after the purchase date.

MENTOR INSTITUTIONAL TRUST

     Mentor  Institutional Trust is a Massachusetts  business trust organized on
February 8, 1994. A copy of the Agreement  and  Declaration  of Trust,  which is
governed by  Massachusetts  law, is on file with the  Secretary  of State of The
Commonwealth of Massachusetts.

   

     The Trust is an open-end series a management investment company with an
unlimited number of authorized shares of beneficial interest.  Shares of the
Trust may, without shareholder  approval, be divided into two or more series of
shares representing separate investment portfolios. Any such series of shares
may be further divided without shareholder  approval into two or more classes of
shares having such preferences and special or relative rights and privileges as
the Trustees determine.  The Trust's  shares are  currently  divided into five
series,  one representing  the Fund, the others  representing  other funds with
varying investment  objectives  and  policies.  Each  share has one vote,  with
fractional shares voting proportionally. Shares of each class will vote together
as a single class except when  required by law or  determined  by the  Trustees.
Shares  of the Fund are  freely  transferable,  are  entitled  to  dividends  as
declared by the Trustees,  and, if the Fund were  liquidated,  would receive the
net assets of the Fund. The Trust may suspend the sale of shares at any time and
may refuse any order to purchase  shares.  Although the Trust and the Portfolio
are not required to hold annual meetings of its shareholders,  shareholders have
the right to call a meeting to elect or remove Trustees, or to take other
actions as provided in the Agreement and Declaration of Trust.


    
   

     In the  interest  of  economy  and  convenience,  the Fund  will not  issue
certificates for its shares except at the shareholder's request.

CUSTODIAN AND TRANSFER AND DIVIDEND AGENT

     Central Fidelity  National Bank serves as the Fund's custodian and transfer
and dividend agent. The address of Central  Fidelity  National Bank is 1021 East
Cary Street, P.O. Box 27602, Richmond, Virginia 23261.

PERFORMANCE INFORMATION


    
   
     The Fund's  "yield" is computed by  determining  the percentage net change,
excluding  capital  changes,  in the value of an  investment in one share of the
Fund  over the  base  period,  and  multiplying  the net  change  by  365/7  (or
approximately 52 weeks).  The Fund's  "effective yield" represents a compounding
of the yield by adding 1 to the number  representing  the  percentage  change in
value of the  investment  during the base  period,  raising  that sum to a power
equal to 365/7, and subtracting 1 from the result.
    

     Past performance does not predict future results.  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 to those of other mutual funds and other
investment vehicles.

                             INVESTMENT RESTRICTIONS

         As fundamental investment  restrictions,  which may not be changed with
respect to a  Portfolio  without  approval  by the  holders of a majority of the
outstanding shares of that Portfolio, a Portfolio may not:

         1.       Purchase any security (other than U.S. Government  securities)
                  if as a  result:  (i)  as to  75% of  such  Portfolio's  total
                  assets, more than 5% of the Portfolio's total assets (taken at
                  current  value)  would then be  invested  in  securities  of a
                  single issuer,  or (ii) more than 25% of the Portfolio's total
                  assets  would be  invested in a single  industry;  except that
                  Mentor Cash Management  Portfolio may invest up to 100% of its
                  assets in securities of issuers in the banking industry.

         2.       Acquire more than 10% of the voting securities of any issuer.

         3.       Act as  underwriter  of securities of other issuers  except to
                  the  extent  that,  in  connection  with  the  disposition  of
                  portfolio  securities,  it may be deemed to be an  underwriter
                  under certain federal securities laws.

         4.       Issue any class of securities which is senior to the
                  Portfolio's shares of beneficial interest.

         5.       Purchase or sell  securities  on margin  (but a Portfolio  may
                  obtain such  short-term  credits as may be  necessary  for the
                  clearance of  transactions).  (Margin  payments in  connection
                  with  transactions in futures  contracts,  options,  and other
                  financial  instruments  are not  considered to constitute  the
                  purchase of securities on margin for this purpose.)

         6.       Purchase or sell real estate or interests in real estate,
                  including real estate mortgage loans, although it may purchase
                  and sell securities which are secured by




<PAGE>



                  real estate and securities of companies that invest or deal in
                  real estate or real estate limited partnership interests. (For
                  purposes of this  restriction,  investments  by a Portfolio in
                  mortgage-backed  securities and other securities  representing
                  interests in mortgage  pools shall not constitute the purchase
                  or sale of real  estate or  interests  in real  estate or real
                  estate mortgage loans.)

         7.       (All  Portfolios  other than Mentor  International  Portfolio)
                  Borrow  money in excess of 5% of the value (taken at the lower
                  of cost or current  value) of its 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.

                  (Mentor  International  Portfolio)  Borrow more than 331/3% of
                  the  value  of its  total  assets  less  all  liabilities  and
                  indebtedness  (other than such  borrowings) not represented by
                  senior securities.

         8.       (All  Portfolios  other than Mentor  International  Portfolio)
                  Pledge,  hypothecate,  mortgage,  or  otherwise  encumber  its
                  assets in excess of 15% of its total assets  (taken at current
                  value) and then only to secure  borrowings  permitted by these
                  investment restrictions.

         9.       Purchase or sell  commodities or commodity  contracts,  except
                  that a  Portfolio  may  purchase  or  sell  financial  futures
                  contracts,   options  on  futures   contracts,   and   futures
                  contracts,  forward  contracts,  and options  with  respect to
                  foreign currencies, and may enter into swap transactions.

         10.      Make loans,  except by purchase of debt  obligations  in which
                  the  Portfolio  may  invest  consistent  with  its  investment
                  policies or by entering into repurchase agreements.

         In  addition,  it is  contrary  to the  current  policy  of each of the
Portfolios, which policy may be changed without shareholder approval, to:

         1.       Invest  in oil,  gas,  or other  mineral  leases,  rights,  or
                  royalty  contracts or in real estate  (although  the Portfolio
                  may invest in securities of issuers that invest or deal in the
                  foregoing types of assets or securities that are secured by or
                  represent interests in real estate).

         2.       Invest in (a) securities which at the time of such investment
                  are not readily marketable, (b) securities restricted as to
                  resale, and (c) repurchase agreements


<PAGE>



                  maturing in more than seven days,  if, as a result,  more than
                  15% (10% with respect to Mentor Cash Management  Portfolio) of
                  the Portfolio's net assets (taken at current value) would then
                  be invested in securities described in (a), (b), and (c).

         3.       Invest in securities of other registered investment companies,
                  except  by  purchases  in  the  open  market   involving  only
                  customary  brokerage  commissions and as a result of which not
                  more than 5% of its total  assets  (taken  at  current  value)
                  would be invested in such  securities,  or except as part of a
                  merger, consolidation, or other acquisition.
   
         4.       Make short sales or purchase puts, calls, straddles, spreads,
                  or any combination thereof (other than futures contracts,
                  options on futures contracts or indices, and options on
                  foreign currencies).
    
         5.       Invest in securities of any issuer if, to the knowledge of the
                  Portfolio, officers and Trustees of the Portfolio and officers
                  and directors of Commonwealth  who  beneficially own more than
                  0.5% of the shares or securities  of that issuer  together own
                  more than 5%.

         All percentage  limitations  on  investments  will apply at the time of
investment and shall not be considered  violated  unless an excess or deficiency
occurs or exists  immediately  after and as a result of such investment.  Except
for the  investment  restrictions  listed above as  fundamental or to the extent
designated  as such in a  Prospectus  with  respect  to a  Portfolio,  the other
investment  policies  described in this  Statement  or in a  Prospectus  are not
fundamental  and may be  changed by  approval  of the  Trustees.  As a matter of
policy,  the  Trustees  would not  materially  change a  Portfolio's  investment
objectives without shareholder approval.

         With  respect to  fundamental  restriction  1, Mentor  Cash  Management
Portfolio  currently  expects to invest in certificates  of deposit,  commercial
paper, and banker's acceptances issued by issuers in the banking industry.

         The  Investment  Company  Act of 1940,  as amended  (the  "1940  Act"),
provides that a "vote of a majority of the outstanding  voting  securities" of a
Portfolio means the  affirmative  vote of the lesser of (1) more than 50% of the
outstanding  shares of the Portfolio,  and (2) 67% or more of the shares present
at a meeting if more than 50% of the  outstanding  shares are represented at the
meeting in person or by proxy.

                         CERTAIN INVESTMENT TECHNIQUES

         Set forth below is information concerning certain investment techniques
in which one or more of the Portfolios may engage, and certain of the risks they
may entail.  Certain of the  investment  techniques  may not be  available  to a
Portfolio. See "Investment objective(s) and




<PAGE>



policies" in the Trust's Prospectuses for a description of the investment
techniques available to a particular Portfolio.

Forward Commitments

         A Portfolio may enter into contracts to purchase securities for a fixed
price at a future date beyond customary settlement time ("forward  commitments")
if the Portfolio  holds, and maintains until the settlement date in a segregated
account, cash or high-grade debt obligations in an amount sufficient to meet the
purchase  price, or if the Portfolio  enters into  offsetting  contracts for the
forward sale of other securities it owns. Forward  commitments may be considered
securities  in  themselves,  and  involve  a risk of loss  if the  value  of the
security to be purchased declines prior to the settlement date, which risk is in
addition to the risk of decline in the value of the  Portfolio's  other  assets.
Where such purchases are made through dealers, the Portfolios rely on the dealer
to consummate the sale. The dealer's  failure to do so may result in the loss to
the Portfolio of an advantageous yield or price.

         Although a Portfolio will generally enter into forward commitments with
the intention of acquiring securities for its portfolio or for delivery pursuant
to  options  contracts  it has  entered  into,  a  Portfolio  may  dispose  of a
commitment prior to settlement if its investment adviser deems it appropriate to
do so. A  Portfolio  may realize  short-term  profits or losses upon the sale of
forward commitments.

Repurchase Agreements

         A  Portfolio  may  enter  into  repurchase  agreements.   A  repurchase
agreement  is a contract  under which the  Portfolio  acquires a security  for a
relatively  short  period  (usually  not more  than  one  week)  subject  to the
obligation of the seller to repurchase and the Portfolio to resell such security
at a fixed time and price (representing the Portfolio's cost plus interest).  It
is the Trust's present  intention to enter into repurchase  agreements only with
member  banks of the  Federal  Reserve  System and  securities  dealers  meeting
certain criteria as to creditworthiness  and financial condition  established by
the  Trustees  of the Trust and only with  respect  to  obligations  of the U.S.
government or its agencies or instrumentalities or other high quality short term
debt  obligations.  Repurchase  agreements may also be viewed as loans made by a
Portfolio which are collateralized by the securities subject to repurchase.  The
investment  adviser will monitor such  transactions  to ensure that the value of
the  underlying  securities  will be at least  equal at all  times to the  total
amount of the  repurchase  obligation,  including  the interest  factor.  If the
seller defaults,  a Portfolio could realize a loss on the sale of the underlying
security to the extent that the proceeds of sale including  accrued interest are
less than the resale price  provided in the  agreement  including  interest.  In
addition,  if  the  seller  should  be  involved  in  bankruptcy  or  insolvency
proceedings,  a Portfolio  may incur  delay and costs in selling the  underlying
security  or may suffer a loss of  principal  and  interest  if a  Portfolio  is
treated  as  an  unsecured  creditor  and  required  to  return  the  underlying
collateral to the seller's estate.




<PAGE>



When-Issued Securities

         A  Portfolio   may  from  time  to  time   purchase   securities  on  a
"when-issued"  basis.  Debt securities are often issued on this basis. The price
of such securities,  which may be expressed in yield terms, is fixed at the time
a commitment to purchase is made,  but delivery and payment for the  when-issued
securities  take place at a later date.  Normally,  the  settlement  date occurs
within  one month of the  purchase.  During  the  period  between  purchase  and
settlement,  no payment is made by a Portfolio  and no  interest  accrues to the
Portfolio. To the extent that assets of a Portfolio are held in cash pending the
settlement of a purchase of  securities,  that  Portfolio  would earn no income.
While a Portfolio may sell its right to acquire when-issued  securities prior to
the settlement  date, a Portfolio  intends  actually to acquire such  securities
unless a sale prior to settlement appears desirable for investment  reasons.  At
the  time  a  Portfolio  makes  the  commitment  to  purchase  a  security  on a
when-issued basis, it will record the transaction and reflect the amount due and
the value of the security in determining the  Portfolio's  net asset value.  The
market value of the when-issued securities may be more or less than the purchase
price payable at the  settlement  date. A Portfolio  will establish a segregated
account in which it will maintain cash and U.S.  Government  Securities or other
high-grade  debt  obligations  at  least  equal  in  value  to  commitments  for
when-issued  securities.  Such segregated  securities  either will mature or, if
necessary, be sold on or before the settlement date.

Collateralized mortgage obligations; other mortgage-related securities

         Collateralized  mortgage  obligations or "CMOs" are debt obligations or
pass-through   certificates   collateralized   by  mortgage  loans  or  mortgage
pass-through  securities.  Typically,  CMOs are  collateralized  by certificates
issued by the Government National Mortgage  Association,  ("GNMA"),  the Federal
National  Mortgage  Association  ("FNMA"),  or the  Federal  Home Loan  Mortgage
Corporation  ("FHLMC"),  but they also may be  collateralized  by whole loans or
private  pass-through  certificates  (such collateral  collectively  hereinafter
referred  to  as  "Mortgage  Assets").   CMOs  may  be  issued  by  agencies  or
instrumentalities  of the U.S.  Government,  or by  private  originators  of, or
investors in, mortgage loans.

         In a CMO,  a series of bonds or  certificates  is  generally  issued in
multiple  classes.  Each class of CMOs is issued at a specific fixed or floating
rate coupon and has a stated  maturity  or final  distribution  date.  Principal
prepayments   on  the  Mortgage   Assets  may  cause  the  CMOs  to  be  retired
substantially  earlier than their stated maturities or final distribution dates.
Interest is paid or accrues on most classes of the CMOs on a monthly, quarterly,
or semi-annual  basis.  The principal of and interest on the Mortgage Assets may
be allocated among the several classes of a series of a CMO in innumerable ways.
In a CMO,  payments of principal,  including any principal  prepayments,  on the
Mortgage  Assets are  applied to the  classes of the series in a  pre-determined
sequence.

Zero-Coupon Securities

         Zero-coupon  securities  in  which a  Portfolio  may  invest  are  debt
obligations  which are  generally  issued at a discount  and  payable in full at
maturity,  and which do not provide for  current  payments of interest  prior to
maturity.  Zero-coupon  securities  usually  trade at a deep discount from their
face or par value and are  subject to greater  market  value  fluctuations  from
changing  interest rates than debt  obligations of comparable  maturities  which
make  current  distributions  of interest.  As a result,  the net asset value of
shares of a Portfolio  investing in zero-coupon  securities  may fluctuate over
a greater range than shares of other mutual funds  investing in securities
making current distributions of interest and having similar maturities.

         Zero-coupon  securities may include U.S. Treasury bills issued directly
by the U.S. Treasury or other short-term debt obligations, and longer-term bonds
or notes and their unmatured interest coupons which have been separated by their
holder,  typically a custodian  bank or investment  brokerage  firm. A number of
securities  firms  and  banks  have  stripped  the  interest  coupons  from  the
underlying  principal (the "corpus") of U.S. Treasury securities and resold them
in  custodial  receipt  programs  with a number of  different  names,  including
Treasury  Income  Growth  Receipts  ("TIGRS")  and  Certificates  of  Accrual on
Treasuries ("CATS"). The underlying U.S. Treasury bonds and notes themselves are
held in  book-entry  form at the Federal  Reserve Bank or, in the case of bearer
securities  (i.e.,  unregistered  securities  which are owned  ostensibly by the
bearer or holder thereof), in trust on behalf of the owners thereof.

         In addition,  the Treasury  has  facilitated  transfers of ownership of
zero-coupon  securities by accounting separately for the beneficial ownership of
particular  interest coupons and corpus payments on Treasury  securities through
the Federal  Reserve  book-entry  record-keeping  system.  The  Federal  Reserve
program as  established  by the  Treasury  Department  is known as  "STRIPS"  or
"Separate Trading of Registered Interest and Principal of Securities." Under the
STRIPS  program,  a Portfolio will be able to have its  beneficial  ownership of
U.S.  Treasury  zero-coupon  securities  recorded  directly  in  the  book-entry
record-keeping  system in lieu of having to hold certificates or other evidences
of ownership of the underlying U.S. Treasury securities.

         When debt  obligations  have been stripped of their unmatured  interest
coupons by the holder,  the stripped coupons are sold separately.  The principal
or corpus is sold at a deep discount  because the buyer  receives only the right
to receive a future  fixed  payment on the  security  and does not  receive  any
rights to periodic cash  interest  payments.  Once  stripped or  separated,  the
corpus and  coupons  may be sold  separately.  Typically,  the  coupons are sold
separately or grouped with other  coupons with like  maturity  dates and sold in
such  bundled  form.  Purchasers  of stripped  obligations  acquire,  in effect,
discount  obligations  that  are  economically   identical  to  the  zero-coupon
securities issued directly by the obligor.

         Zero-coupon  securities  allow an issuer to avoid the need to  generate
cash to meet current interest payments.  Even though  zero-coupon  securities do
not pay current interest in cash, a




<PAGE>



Portfolio  is  nonetheless  required  to accrue  interest  income on them and to
distribute the amount of that interest at least annually to shareholders.  Thus,
a Portfolio could be required at times to liquidate  other  investments in order
to satisfy its distribution requirement.

         Options

         A Portfolio may purchase and sell put and call options on its portfolio
securities to enhance  investment  performance and to protect against changes in
market prices.

         Covered call options. A Portfolio may write covered call options on its
securities to realize a greater  current  return through the receipt of premiums
than it would realize on its securities alone. Such option transactions may also
be used  as a  limited  form of  hedging  against  a  decline  in the  price  of
securities owned by the Portfolio.

         A call option gives the holder the right to purchase, and obligates the
writer  to sell,  a  security  at the  exercise  price at any  time  before  the
expiration  date. A call option is  "covered" if the writer,  at all times while
obligated as a writer,  either owns the  underlying  securities  (or  comparable
securities  satisfying the cover requirements of the securities  exchanges),  or
has the  right to  acquire  such  securities  through  immediate  conversion  of
securities.

         In return  for the  premium  received  when it  writes a  covered  call
option,  a Portfolio  gives up some or all of the  opportunity to profit from an
increase in the market price of the  securities  covering the call option during
the life of the option.  The Portfolio retains the risk of loss should the price
of such securities  decline.  If the option expires  unexercised,  the Portfolio
realizes a gain equal to the premium,  which may be offset by a decline in price
of the underlying security. If the option is exercised, the Portfolio realizes a
gain or loss  equal  to the  difference  between  the  Portfolio's  cost for the
underlying  security and the proceeds of sale (exercise price minus commissions)
plus the amount of the premium.

         A Portfolio may  terminate a call option that it has written  before it
expires by entering into a closing purchase  transaction.  A Portfolio may enter
into  closing  purchase  transactions  in  order  to free  itself  to  sell  the
underlying  security or to write another call on the security,  realize a profit
on a previously  written call option, or protect a security from being called in
an unexpected  market rise. Any profits from a closing purchase  transaction may
be offset by a decline  in the  value of the  underlying  security.  Conversely,
because  increases in the market price of a call option will  generally  reflect
increases in the market price of the  underlying  security,  any loss  resulting
from a closing  purchase  transaction is likely to be offset in whole or in part
by unrealized appreciation of the underlying security owned by the Portfolio.

         Covered put options. A Portfolio may write covered put options in order
to enhance its current return.  Such options  transactions may also be used as a
limited form of hedging  against an increase in the price of securities that the
Portfolio plans to purchase. A put option




<PAGE>



gives the holder the right to sell,  and obligates the writer to buy, a security
at the exercise  price at any time before the  expiration  date. A put option is
"covered"  if  the  writer  segregates  cash  and  high-grade   short-term  debt
obligations or other permissible collateral equal to the price to be paid if the
option is exercised.

         In addition to the receipt of  premiums  and the  potential  gains from
terminating  such options in closing  purchase  transactions,  a Portfolio  also
receives  interest  on the cash  and debt  securities  maintained  to cover  the
exercise price of the option. By writing a put option, the Portfolio assumes the
risk that it may be required to purchase the underlying security for an exercise
price  higher  than its then  current  market  value,  resulting  in a potential
capital loss unless the security later appreciates in value.

         A Portfolio  may  terminate a put option that it has written  before it
expires by a closing purchase transaction. Any loss from this transaction may be
partially or entirely offset by the premium received on the terminated option.

         Purchasing  put and call  options.  A Portfolio  may also  purchase put
options to protect  portfolio  holdings against a decline in market value.  This
protection  lasts for the life of the put option  because  the  Portfolio,  as a
holder of the option,  may sell the  underlying  security at the exercise  price
regardless of any decline in its market  price.  In order for a put option to be
profitable,   the  market  price  of  the   underlying   security  must  decline
sufficiently below the exercise price to cover the premium and transaction costs
that the  Portfolio  must pay.  These costs will reduce any profit the Portfolio
might have realized had it sold the  underlying  security  instead of buying the
put option.

         A Portfolio  may purchase  call options to hedge against an increase in
the price of securities that the Portfolio  wants  ultimately to buy. Such hedge
protection is provided  during the life of the call option since the  Portfolio,
as holder of the call  option,  is able to buy the  underlying  security  at the
exercise price  regardless of any increase in the underlying  security's  market
price.  In order for a call  option to be  profitable,  the market  price of the
underlying security must rise sufficiently above the exercise price to cover the
premium and transaction  costs. These costs will reduce any profit the Portfolio
might  have  realized  had it  bought  the  underlying  security  at the time it
purchased the call option.

         A  Portfolio  may also  purchase  put and call  options to enhance  its
current return.

         Options on foreign securities. The Trust may, on behalf of a Portfolio,
purchase  and sell  options  on  foreign  securities  if in the  opinion  of its
investment advisor the investment characteristics of such options, including the
risks  of  investing  in such  options,  are  consistent  with  the  Portfolio's
investment  objectives.  It is expected  that risks related to such options will
not differ materially from risks related to options on U.S. securities. However,
position  limits and other rules of foreign  exchanges  may differ from those in
the U.S.  In  addition,  options  markets in some  countries,  many of which are
relatively new, may be less liquid than comparable markets in the U.S.




<PAGE>



         Risks  involved in the sale of options.  Options  transactions  involve
certain risks,  including the risks that a Portfolio's  investment  adviser will
not forecast interest rate or market movements  correctly,  that a Portfolio may
be unable at times to close out such positions, or that hedging transactions may
not  accomplish  their purpose  because of imperfect  market  correlations.  The
successful  use of these  strategies  depends on the  ability  of a  Portfolio's
investment adviser to forecast market and interest rate movements correctly.

         An  exchange-listed  option may be closed out only on an exchange which
provides  a  secondary  market  for an  option of the same  series.  There is no
assurance  that a liquid  secondary  market on an  exchange  will  exist for any
particular  option or at any  particular  time.  If no secondary  market were to
exist,  it would be impossible to enter into a closing  transaction to close out
an option position.  As a result, a Portfolio may be forced to continue to hold,
or to purchase at a fixed price,  a security on which it has sold an option at a
time when its investment adviser believes it is inadvisable to do so.

         Higher  than  anticipated  trading  activity  or  order  flow or  other
unforeseen events might cause The Options Clearing Corporation or an exchange to
institute  special trading  procedures or  restrictions  that might restrict the
Trust's  use of options.  The  exchanges  have  established  limitations  on the
maximum number of calls and puts of each class that may be held or written by an
investor or group of investors acting in concert.  It is possible that the Trust
and other clients of the Portfolios'  investment advisers may be considered such
a group.  These position  limits may restrict the Trust's ability to purchase or
sell options on particular securities.

         Options  which are not traded on national  securities  exchanges may be
closed out only with the other party to the option transaction. For that reason,
it may be more  difficult  to close out unlisted  options  than listed  options.
Furthermore,  unlisted  options  are  not  subject  to the  protection  afforded
purchasers of listed options by The Options Clearing Corporation.

         Government regulations, particularly the requirements for qualification
as a "regulated  investment  company" under the Internal  Revenue Code, may also
restrict the Trust's use of options.

Futures Contracts

         In order to hedge  against  the  effects  of adverse  market  changes a
Portfolio  may buy and sell  futures  contracts.  A Portfolio  may also,  to the
extent  permitted by applicable law, buy and sell futures  contracts and options
on futures  contracts  to increase  the  Portfolio's  current  return.  All such
futures and related  options  will,  as may be  required by  applicable  law, be
traded on exchanges  that are licensed and  regulated by the  Commodity  Futures
Trading Commission (the "CFTC").





<PAGE>



         Index  Futures  Contracts  and Options.  A Portfolio may invest in debt
index  futures  contracts  and stock  index  futures  contracts,  and in related
options.  A debt index futures  contract is a contract to buy or sell units of a
specified debt index at a specified  future date at a price agreed upon when the
contract is made. A unit is the current  value of the index.  Debt index futures
in which the Portfolios are presently  expected to invest are not now available,
although such futures  contracts are expected to become available in the future.
A stock  index  futures  contract  is a contract to buy or sell units of a stock
index at a  specified  future date at a price  agreed upon when the  contract is
made. A unit is the current value of the stock index.

         The following example  illustrates  generally the manner in which index
futures contracts operate.  The Standard & Poor's 100 Stock Index is composed of
100  selected  common  stocks,  most of which are  listed on the New York  Stock
Exchange.  The S&P 100 Index  assigns  relative  weightings to the common stocks
included  in the  Index,  and the Index  fluctuates  with  changes in the market
values of those common stocks.  In the case of the S&P 100 Index,  contracts are
to buy or sell 100 units. Thus, if the value of the S&P 100 Index were $180, one
contract  would be worth  $18,000  (100 units x $180).  The stock index  futures
contract  specifies  that no delivery of the actual  stocks  making up the index
will take place. Instead,  settlement in cash must occur upon the termination of
the contract,  with the  settlement  being the  difference  between the contract
price and the actual level of the stock index at the expiration of the contract.
For example,  if a Portfolio  enters into a futures contract to buy 100 units of
the S&P 100 Index at a specified future date at a contract price of $180 and the
S&P 100 Index is at $184 on that future date,  the Portfolio will gain $400 (100
units x gain of $4). If the Portfolio enters into a futures contract to sell 100
units of the stock index at a specified  future date at a contract price of $180
and the S&P 100 Index is at $182 on that future date,  the  Portfolio  will lose
$200 (100 units x loss of $2).

         A Portfolio may purchase or sell futures  contracts with respect to any
securities  indexes.  Positions  in index  futures  may be closed out only on an
exchange or board of trade which provides a secondary market for such futures.

         In order to hedge a Portfolio's investments  successfully using futures
contracts and related options, a Portfolio must invest in futures contracts with
respect to indexes or  subindexes  the movements of which will, in its judgment,
have a significant  correlation  with movements in the prices of the Portfolio's
securities.

         Options on index futures contracts are similar to options on securities
except that options on index futures  contracts give the purchaser the right, in
return for the premium paid,  to assume a position in an index futures  contract
(a long position if the option is a call and a short position if the option is a
put) at a specified  exercise price at any time during the period of the option.
Upon  exercise of the option,  the holder  would assume the  underlying  futures
position  and would  receive a variation  margin  payment of cash or  securities
approximating  the increase in the value of the holder's option position.  If an
option is exercised on the last




<PAGE>



trading day prior to the expiration  date of the option,  the settlement will be
made entirely in cash based on the difference  between the exercise price of the
option and the closing level of the index on which the futures contract is based
on the expiration date. Purchasers of options who fail to exercise their options
prior to the exercise date suffer a loss of the premium paid.

         As an  alternative  to  purchasing  and selling call and put options on
index  futures  contracts,  each of the  Portfolios  which may purchase and sell
index  futures  contracts  may  purchase  and sell call and put  options  on the
underlying  indexes  themselves  to the extent  that such  options are traded on
national  securities  exchanges.   Index  options  are  similar  to  options  on
individual  securities  in that the  purchaser of an index  option  acquires the
right to buy (in the  case of a call)  or sell  (in the case of a put),  and the
writer  undertakes  the obligation to sell or buy (as the case may be), units of
an index at a stated  exercise  price during the term of the option.  Instead of
giving the right to take or make actual delivery of securities, the holder of an
index option has the right to receive a cash "exercise settlement amount".  This
amount is equal to the  amount by which the fixed  exercise  price of the option
exceeds  (in the  case of a put) or is less  than  (in the  case of a call)  the
closing value of the underlying index on the date of the exercise, multiplied by
a fixed "index multiplier".

         A Portfolio  may purchase or sell options on stock  indices in order to
close out its  outstanding  positions in options on stock  indices  which it has
purchased. A Portfolio may also allow such options to expire unexercised.

         Compared to the purchase or sale of futures contracts,  the purchase of
call or put  options on an index  involves  less  potential  risk to a Portfolio
because the  maximum  amount at risk is the  premium  paid for the options  plus
transactions  costs.  The writing of a put or call  option on an index  involves
risks  similar to those risks  relating to the purchase or sale of index futures
contracts.

         Margin  Payments.  When  a  Portfolio  purchases  or  sells  a  futures
contract,  it is required to deposit with its custodian an amount of cash,  U.S.
Treasury bills, or other  permissible  collateral equal to a small percentage of
the amount of the futures  contract.  This amount is known as "initial  margin".
The  nature of  initial  margin  is  different  from that of margin in  security
transactions   in  that  it  does  not  involve   borrowing   money  to  finance
transactions.  Rather,  initial margin is similar to a performance  bond or good
faith deposit that is returned to a Portfolio upon  termination of the contract,
assuming a Portfolio satisfies its contractual obligations.

         Subsequent  payments to and from the broker occur on a daily basis in a
process  known as "marking  to market".  These  payments  are called  "variation
margin" and are made as the value of the underlying futures contract fluctuates.
For  example,  when a Portfolio  sells a futures  contract  and the value of the
underlying  index rises  above the  delivery  price,  the  Portfolio's  position
declines in value. The Portfolio then pays the broker a variation margin




<PAGE>



payment  equal to the  difference  between  the  delivery  price of the  futures
contract and the value of the index underlying the futures contract. Conversely,
if the price of the  underlying  index  falls  below the  delivery  price of the
contract,  the Portfolio's  futures position increases in value. The broker then
must  make a  variation  margin  payment  equal to the  difference  between  the
delivery price of the futures contract and the value of the index underlying the
futures contract.

         When a Portfolio  terminates a position in a futures contract,  a final
determination of variation margin is made,  additional cash is paid by or to the
Portfolio,   and  the  Portfolio  realizes  a  loss  or  a  gain.  Such  closing
transactions involve additional commission costs.

Special Risks of Transactions in Futures Contracts and Related Options

         Liquidity risks.  Positions in futures contracts may be closed out only
on an  exchange or board of trade  which  provides a  secondary  market for such
futures.  Although  the  Trust  intends  to  purchase  or sell  futures  only on
exchanges  or boards of trade  where  there  appears  to be an active  secondary
market,  there is no assurance that a liquid  secondary market on an exchange or
board of trade will exist for any particular contract or at any particular time.
If there is not a liquid  secondary  market at a particular  time, it may not be
possible  to close a futures  position at such time and, in the event of adverse
price  movements,  a Portfolio  would continue to be required to make daily cash
payments of variation margin.  However,  in the event financial futures are used
to hedge portfolio securities,  such securities will not generally be sold until
the financial futures can be terminated.  In such circumstances,  an increase in
the price of the  portfolio  securities,  if any, may  partially  or  completely
offset losses on the financial futures.

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

         Hedging risks.  There are several risks in connection with the use by a
Portfolio of futures contracts and related options as a hedging device. One risk
arises because of the imperfect  correlation  between movements in the prices of
the futures  contracts  and options and  movements  in the  underlying  index or
movements in the prices of a Portfolio's  securities  which are the subject of a
hedge. A Portfolio's  investment adviser will,  however,  attempt to reduce this
risk by purchasing and selling,  to the extent possible,  futures  contracts and
related




<PAGE>



options on securities  and indexes the movements of which will, in its judgment,
correlate  closely with movements in the value of the  underlying  index and the
Portfolio's portfolio securities sought to be hedged.

         Successful  use of futures  contracts  and options by a  Portfolio  for
hedging purposes is also subject to its investment  adviser's ability to predict
correctly movements in the direction of the market. It is possible that, where a
Portfolio has purchased puts on futures contracts to hedge its portfolio against
a decline in the market,  the index on which the puts are purchased may increase
in value and the value of securities held in the portfolio may decline.  If this
occurred,  the  Portfolio  would  lose money on the puts and also  experience  a
decline  in value in its  portfolio  securities.  In  addition,  the  prices  of
futures,  for a number of reasons, may not correlate perfectly with movements in
the underlying index due to certain market distortions.  First, all participants
in  the  futures  market  are  subject  to  margin  deposit  requirements.  Such
requirements may cause investors to close futures contracts  through  offsetting
transactions which could distort the normal relationship  between the underlying
index and  futures  markets.  Second,  the margin  requirements  in the  futures
markets are less onerous than margin  requirements in the securities  markets in
general,  and as a result the futures markets may attract more  speculators than
the securities markets do. Increased participation by speculators in the futures
markets may also cause  temporary price  distortions.  Due to the possibility of
price  distortion,  even a  correct  forecast  of  general  market  trends  by a
Portfolio's  investment  adviser  may still not result in a  successful  hedging
transaction over a very short time period.

         Other Risks. A Portfolio will incur  brokerage fees in connection  with
its futures and options transactions.  In addition,  while futures contracts and
options on futures will be purchased  and sold to reduce  certain  risks,  those
transactions  themselves entail certain other risks. Thus, while a Portfolio may
benefit from the use of futures and related  options,  unanticipated  changes in
interest  rates  or  stock  price  movements  may  result  in a  poorer  overall
performance  for the  Portfolio  than if it had not  entered  into  any  futures
contracts  or  options  transactions.  Moreover,  in the  event of an  imperfect
correlation  between the futures  position and the portfolio  position  which is
intended to be  protected,  the desired  protection  may not be obtained and the
Portfolio may be exposed to risk of loss, which may be unlimited.

Segregation of Assets
   
         A Portfolio may at times segregate assets in respect of certain
transactions in which the Portfolio  enters into a commitment  to pay money or
deliver  securities  at some  future  date.  Any such  segregated  account  will
be  maintained  by the Trust's  custodian and may contain  cash,  U.S.
government  securities, liquid high grade debt obligations, or other appropriate
assets.

Reverse Repurchase Agreements

         A Portfolio may enter into reverse  repurchase  agreements in which the
Portfolio  sells  securities and agrees to repurchase  them at a mutually agreed
date  and  price.  Generally,  the  effect  of such a  transaction  is that  the
Portfolio  can  recover  all or  most  of the  cash  invested  in the  portfolio
securities involved during the term of the reverse repurchase  agreement,  while
it will be able to keep the  interest  income  associated  with those  portfolio
securities.  Such  transactions  are  advantageous  if the interest  cost to the
Portfolio  of the  reverse  repurchase  transaction  is less  than  the  cost of
otherwise obtaining the cash.

         A Portfolio may also enter into reverse repurchase  agreements in which
the  Portfolio  sells  securities  and agrees to  repurchase  them at a mutually
agreed date and price.  Generally,  the effect of such a transaction is that the
Portfolio  can  recover  all or  most  of the  cash  invested  in the  portfolio
securities involved during the term of the reverse repurchase  agreement,  while
it will be able to keep the  interest  income  associated  with those  portfolio
securities.  Such  transactions  are  advantageous  if the interest  cost to the
Portfolio  of the  reverse  repurchase  transaction  is less  than  the  cost of
otherwise obtaining the cash.

         Reverse  repurchase  agreements  may be  viewed as a  borrowing  by the
Portfolio,  secured by the security  which is the subject of the  agreement.  In
addition  to the  general  risks  involved  in  leveraging,  reverse  repurchase
agreements  involve the risk that, in the event of the  bankruptcy or insolvency
of the  Portfolio's  counterparty,  the Portfolio would be unable to recover the
security  which is the  subject  of the  agreement,  the amount of cash or other
property  transferred by the  counterparty  to the Portfolio under the agreement
prior to such  insolvency  or  bankruptcy is less than the value of the security
subject to the agreement,  or the Portfolio may be delayed or prevented,  due to
such  insolvency  or  bankruptcy,  from  using such cash or  property  or may be
required to return it to the counterparty or its trustee or receiver.

Loans of Portfolio Securities

         A Portfolio may lend its portfolio securities,  provided:  (1) the loan
is secured continuously by collateral consisting of U.S. Government  Securities,
cash, or cash equivalents  adjusted daily to have market value at least equal to
the current market value of the securities  loaned; (2) the Portfolio may at any
time call the loan and  regain  the  securities  loaned;  (3) a  Portfolio  will
receive any interest or  dividends  paid on the loaned  securities;  and (4) the
aggregate  market value of securities  of any  Portfolio  loaned will not at any
time exceed  one-third (or such other limit as the Trustee may establish) of the
total assets of the Portfolio.  In addition,  it is anticipated that a Portfolio
may share with the borrower some of the income  received on the  collateral  for
the loan or that it will be paid a  premium  for the  loan.  Before a  Portfolio
enters into a loan,  its  investment  adviser  considers all relevant  facts and
circumstances  including  the  creditworthiness  of the  borrower.  The risks in
lending  portfolio  securities,  as with other extensions of credit,  consist of
possible delay in recovery of the




<PAGE>



securities or possible loss of rights in the collateral should the borrower fail
financially.  Although  voting  rights or rights to consent  with respect to the
loaned  securities pass to the borrower,  a Portfolio  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 a Portfolio  if the holders of such  securities  are
asked to vote upon or consent to matters materially affecting the investment.  A
Portfolio will not lend portfolio  securities to borrowers  affiliated  with the
Portfolio.

Foreign Securities

         A Portfolio may invest in foreign  securities  and in  certificates  of
deposit issued by United States  branches of foreign banks and foreign  branches
of United States banks.

         Investments in foreign securities may involve considerations  different
from  investments  in  domestic  securities  due to limited  publicly  available
information, non-uniform accounting standards, lower trading volume and possible
consequent illiquidity,  greater volatility in price, the possible imposition of
withholding or confiscatory taxes, the possible adoption of foreign governmental
restrictions  affecting the payment of principal and interest,  expropriation of
assets,  nationalization,  or other adverse political or economic  developments.
Foreign  companies  may not be  subject  to  auditing  and  financial  reporting
standards and  requirements  comparable to those which apply to U.S.  companies.
Foreign  brokerage  commissions and other fees are generally  higher than in the
United States. It may be more difficult to obtain and enforce a judgment against
a foreign issuer.

         In addition,  to the extent that a Portfolio's  foreign investments are
not United States dollar-denominated, the Portfolio may be affected favorably or
unfavorably  by  changes  in  currency   exchange  rates  or  exchange   control
regulations  and  may  incur  costs  in  connection   with  conversion   between
currencies.

         In determining whether to invest in securities of foreign issuers,  the
investment  advisor of a Portfolio  seeking  current  income will  consider  the
likely impact of foreign  taxes on the net yield  available to the Portfolio and
its  shareholders.  Income  received by a Portfolio  from sources within foreign
countries  may be  reduced  by  withholding  and  other  taxes  imposed  by such
countries.  Tax conventions  between certain countries and the United States may
reduce or eliminate such taxes. It is impossible to determine the effective rate
of  foreign  tax in  advance  since  the  amount of a  Portfolio's  assets to be
invested  in  various   countries   is  not  known,   and  tax  laws  and  their
interpretations  may  change  from time to time and may change  without  advance
notice.  Any such taxes paid by a Portfolio will reduce its net income available
for distribution to shareholders.

Foreign Currency Transactions

         A Portfolio  may engage in currency  exchange  transactions  to protect
against  uncertainty in the level of future foreign currency  exchange rates and
to increase current return. A Portfolio may engage in both "transaction hedging"
and "position hedging".

         When it engages in transaction hedging, a Portfolio enters into foreign
currency  transactions  with respect to specific  receivables or payables of the
Portfolio  generally  arising in  connection  with the  purchase  or sale of its
portfolio  securities.  A Portfolio will engage in  transaction  hedging when it
desires  to "lock  in" the U.S.  dollar  price of a  security  it has  agreed to
purchase  or sell,  or the U.S.  dollar  equivalent  of a dividend  or  interest
payment in a foreign currency.  By transaction  hedging a Portfolio will attempt
to  protect  against a possible  loss  resulting  from an adverse  change in the
relationship  between the U.S. dollar and the applicable foreign currency during
the period  between the date on which the  security is  purchased  or sold or on
which the dividend or interest  payment is declared,  and the date on which such
payments are made or received.

         A Portfolio may purchase or sell a foreign currency on a spot (or cash)
basis at the prevailing  spot rate in connection  with  transaction  hedging.  A
Portfolio may also enter into  contracts to purchase or sell foreign  currencies
at a future date ("forward  contracts")  and purchase and sell foreign  currency
futures contracts.

         For  transaction   hedging  purposes  a  Portfolio  may  also  purchase
exchange-listed  and  over-the-counter  call and put options on foreign currency
futures contracts and on foreign currencies.  A put option on a futures contract
gives a Portfolio the right to assume a short  position in the futures  contract
until  expiration of the option.  A put option on currency gives a Portfolio the
right to sell a  currency  at an  exercise  price  until the  expiration  of the
option.  A call  option on a futures  contract  gives a  Portfolio  the right to
assume a long  position  in the futures  contract  until the  expiration  of the
option.  A call  option on currency  gives a  Portfolio  the right to purchase a
currency at the exercise price until the  expiration of the option.  A Portfolio
will   engage   in   over-the-counter   transactions   only   when   appropriate
exchange-traded  transactions  are  unavailable  and when, in the opinion of its
investment adviser, the pricing mechanism and liquidity are satisfactory and the
participants   are  responsible   parties  likely  to  meet  their   contractual
obligations.

         When it engages in position  hedging,  a Portfolio  enters into foreign
currency exchange transactions to protect against a decline in the values of the
foreign  currencies in which securities held by the Portfolio are denominated or
are quoted in their  principle  trading  markets or an  increase in the value of
currency for  securities  which a Portfolio  expects to purchase.  In connection
with position  hedging,  a Portfolio may purchase put or call options on foreign
currency  and  foreign  currency  futures  contracts  and  buy or  sell  forward
contracts




<PAGE>



and foreign currency futures contracts.  A Portfolio may also purchase or sell
foreign currency on a spot basis.

         The  precise  matching  of the  amounts  of foreign  currency  exchange
transactions  and the  value  of the  portfolio  securities  involved  will  not
generally  be  possible  since the future  value of such  securities  in foreign
currencies  will change as a  consequence  of market  movements in the values of
those  securities  between  the dates the  currency  exchange  transactions  are
entered into and the dates they mature.

         It is  impossible  to forecast  with  precision  the market  value of a
Portfolio's  portfolio  securities at the expiration or maturity of a forward or
futures contract.  Accordingly,  it may be necessary for a Portfolio to purchase
additional  foreign  currency  on the spot  market (and bear the expense of such
purchase) if the market value of the security or securities being hedged is less
than the amount of foreign currency a Portfolio is obligated to deliver and if a
decision is made to sell the  security or  securities  and make  delivery of the
foreign  currency.  Conversely,  it may be  necessary to sell on the spot market
some of the foreign currency received upon the sale of the portfolio security or
securities  of a Portfolio  if the market value of such  security or  securities
exceeds the amount of foreign currency the Portfolio is obligated to deliver.

         To  offset  some  of  the  costs  to a  Portfolio  of  hedging  against
fluctuations in currency  exchange  rates,  the Portfolio may write covered call
options on those currencies.

         Transaction and position  hedging do not eliminate  fluctuations in the
underlying  prices  of the  securities  which a  Portfolio  owns or  intends  to
purchase or sell. They simply establish a rate of exchange which one can achieve
at some future point in time.  Additionally,  although these  techniques tend to
minimize the risk of loss due to a decline in the value of the hedged  currency,
they tend to limit any  potential  gain which might  result from the increase in
the value of such currency.

         A Portfolio may also seek to increase its current  return by purchasing
and selling  foreign  currency on a spot basis,  and by  purchasing  and selling
options on foreign currencies and on foreign currency futures contracts,  and by
purchasing and selling foreign currency forward contracts.

         Currency  Forward and Futures  Contracts.  A forward  foreign  currency
exchange contract involves an obligation to purchase or sell a specific currency
at a future  date,  which may be any  fixed  number of days from the date of the
contract as agreed by the parties,  at a price set at the time of the  contract.
In the case of a  cancelable  forward  contract,  the holder has the  unilateral
right to cancel  the  contract  at  maturity  by  paying a  specified  fee.  The
contracts are traded in the interbank market conducted directly between currency
traders (usually large commercial banks) and their customers. A forward contract
generally has no




<PAGE>



deposit  requirement,  and no commissions are charged at any stage for trades. A
foreign  currency  futures  contract is a  standardized  contract for the future
delivery of a specified amount of a foreign currency at a future date at a price
set at the time of the contract.  Foreign currency  futures  contracts traded in
the United States are designed by and traded on exchanges regulated by the CFTC,
such as the New York Mercantile Exchange.

         Forward  foreign  currency  exchange   contracts  differ  from  foreign
currency futures contracts in certain respects.  For example,  the maturity date
of a  forward  contract  may be any  fixed  number  of days from the date of the
contract agreed upon by the parties, rather than a predetermined date in a given
month. Forward contracts may be in any amounts agreed upon by the parties rather
than predetermined  amounts. Also, forward foreign exchange contracts are traded
directly between currency traders so that no intermediary is required. A forward
contract generally requires no margin or other deposit.

         At the  maturity  of a forward or futures  contract,  a  Portfolio  may
either accept or make delivery of the currency specified in the contract,  or at
or prior to maturity enter into a closing transaction  involving the purchase or
sale of an offsetting  contract.  Closing  transactions  with respect to forward
contracts are usually  effected  with the currency  trader who is a party to the
original  forward  contract.   Closing  transactions  with  respect  to  futures
contracts  are  effected  on a  commodities  exchange;  a  clearing  corporation
associated  with  the  exchange  assumes  responsibility  for  closing  out such
contracts.

         Positions in foreign currency futures contracts and related options may
be closed out only on an exchange  or board of trade which  provides a secondary
market in such contracts or options. Although a Portfolio will normally purchase
or sell foreign currency futures contracts and related options only on exchanges
or boards of trade where there appears to be an active secondary  market,  there
is no  assurance  that a secondary  market on an exchange or board of trade will
exist for any particular  contract or option or at any particular  time. In such
event, it may not be possible to close a futures or related option position and,
in the event of adverse  price  movements,  a  Portfolio  would  continue  to be
required  to make  daily  cash  payments  of  variation  margin  on its  futures
positions.

         Foreign  Currency  Options.   Options  on  foreign  currencies  operate
similarly  to  options  on   securities,   and  are  traded   primarily  in  the
over-the-counter  market,  although options on foreign  currencies have recently
been listed on several exchanges. Such options will be purchased or written only
when a Portfolio's  investment  adviser  believes that a liquid secondary market
exists  for such  options.  There can be no  assurance  that a liquid  secondary
market  will exist for a  particular  option at any  specific  time.  Options on
foreign currencies are affected by all of those factors which influence exchange
rates and investments generally.

         The value of a foreign currency option is dependent upon the value of
the foreign currency and the U.S. dollar, and may have no relationship to the
investment merits of a




<PAGE>



foreign  security.  Because  foreign  currency  transactions  occurring  in  the
interbank  market  involve  substantially  larger amounts than those that may be
involved in the use of foreign currency options,  investors may be disadvantaged
by having to deal in an odd lot market (generally  consisting of transactions of
less than $1 million) for the underlying  foreign  currencies at prices that are
less favorable than for round lots.

         There is no systematic  reporting of last sale  information for foreign
currencies  and there is no regulatory  requirement  that  quotations  available
through  dealers or other market  sources be firm or revised on a timely  basis.
Available  quotation  information  is  generally  representative  of very  large
transactions in the interbank market and thus may not reflect relatively smaller
transactions  (less than $1  million)  where  rates may be less  favorable.  The
interbank market in foreign currencies is a global,  around-the-clock market. To
the extent that the U.S.  options  markets are closed  while the markets for the
underlying currencies remain open, significant price and rate movements may take
place in the  underlying  markets that cannot be  reflected in the U.S.  options
markets.

         Settlement Procedures.  Settlement procedures relating to a Portfolio's
investments in foreign securities and to a Portfolio's foreign currency exchange
transactions may be more complex than settlements with respect to investments in
debt or equity  securities of U.S.  issuers,  and may involve  certain risks not
present in a  Portfolio's  domestic  investments.  For  example,  settlement  of
transactions involving foreign securities or foreign currency may occur within a
foreign  country,  and a Portfolio may be required to accept or make delivery of
the underlying  securities or currency in conformity with any applicable U.S. or
foreign restrictions or regulations,  and may be required to pay any fees, taxes
or charges associated with such delivery.  Such investments may also involve the
risk that an entity involved in the settlement may not meet its obligations.

         Foreign Currency  Conversion.  Although foreign exchange dealers do not
charge a fee for  currency  conversion,  they do  realize a profit  based on the
difference  (the  "spread")  between  prices at which they buy and sell  various
currencies.  Thus, a dealer may offer to sell a foreign  currency to a Portfolio
at one rate,  while offering a lesser rate of exchange should a Portfolio desire
to resell that currency to the dealer.

         The Trustees do not receive  pension or  retirement  benefits  from the
Trust.

         The Agreement and  Declaration  of Trust of the Trust provides that the
Trust will indemnify its Trustees and officers against  liabilities and expenses
incurred in connection with




<PAGE>



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 Agreement and
Declaration  of Trust that they have not acted in good  faith in the  reasonable
belief that their  actions were in the best  interests of the Trust or that such
indemnification  would  relieve any officer or Trustee of any  liability  to the
Trust or its  Shareholders by reason of willful  misfeasance,  bad faith,  gross
negligence,  or  reckless  disregard  of his or her  duties.  The Trust,  at its
expense,  provides  liability  insurance  for the  benefit of its  Trustees  and
officers.

                     INVESTMENT ADVISORY AND OTHER SERVICES

         Each of Commonwealth and Mentor Perpetual act as investment advisers to
the  respective  Portfolios  pursuant to  Management  Contracts  with the Trust.
Mentor Investment Group acts as administrator to each of the Portfolios pursuant
to an  Administration  Agreement with the Trust.  Subject to the supervision and
direction of the Trustees, each investment adviser




<PAGE>



manages a Portfolio's  portfolio in accordance  with the stated policies of that
Portfolio and of the Trust.  The investment  advisers make investment  decisions
for the  Portfolios  and  place  the  purchase  and sale  orders  for  portfolio
transactions.  Mentor furnishes each of the Portfolios with certain  statistical
and research data, clerical help, and certain accounting,  data processing,  and
other  services  required by the  Portfolios,  assists in preparation of certain
reports to shareholders of the Portfolios, tax returns, and filings with the SEC
and state Blue Sky  authorities,  and  generally  assists in all  aspects of the
Portfolios'  operations.  Each  investment  adviser  and  Mentor  bear all their
expenses in connection with the performance of their services. In addition,  the
investment  advisers and Mentor pay the  salaries of all officers and  employees
who are employed by them and the Trust.

         The investment advisers provide the Portfolios with investment officers
who are  authorized  to execute  purchases and sales of  securities.  Investment
decisions for the Portfolios and for the other investment advisory clients of an
investment  adviser and its affiliates  are made with a view to achieving  their
respective investment  objectives.  Investment decisions are the product of many
factors in addition to basic  suitability  for the particular  client  involved.
Thus,  a  particular  security  may be bought or sold for certain  clients  even
though it could  have been  bought or sold for other  clients  at the same time.
Likewise,  a particular  security may be bought for one or more clients when one
or more other clients are selling the security.  In some  instances,  one client
may sell a particular security to another client. It also sometimes happens that
two or more clients simultaneously  purchase or sell the same security, in which
event  each day's  transactions  in such  security  are,  insofar  as  possible,
averaged as to price and allocated between such clients in a manner which in the
investment  adviser's  opinion is equitable to each and in  accordance  with the
amount  being  purchased  or sold  by  each.  There  may be  circumstances  when
purchases or sales of portfolio  securities for one or more clients will have an
adverse  effect on other  clients.  In the case of short-term  investments,  the
Treasury area of Wheat First Butcher  Singer  handles  purchases and sales under
guidelines approved by investment officers of the Trust. The investment advisers
employ  professional  staffs of  portfolio  managers  who draw upon a variety of
resources,  including  Wheat  for  research  information  for  their  respective
Portfolios.

         The proceeds  received by each  Portfolio for each issue or sale of its
shares, and all income, earnings, profits, and proceeds thereof, subject only to
the rights of creditors,  will be specifically allocated to such Portfolio,  and
constitute the underlying  assets of that  Portfolio.  The underlying  assets of
each Portfolio  will be segregated on the Trust's books of account,  and will be
charged with the  liabilities  in respect of such  Portfolio and with a share of
the general  liabilities of the Trust.  Expenses with respect to any two or more
Portfolios  may be  allocated  in  proportion  to the net  asset  values  of the
respective  Portfolios except where allocations of direct expenses can otherwise
be fairly made.

         Expenses  incurred  in  the  operation  of  a  Portfolio  or  otherwise
allocated  to a  Portfolio,  including  but  not  limited  to  taxes,  interest,
brokerage fees and commissions, fees to Trustees who




<PAGE>



are not officers,  directors,  stockholders, or employees of Wheat First Butcher
Singer  and  subsidiaries,  SEC  fees  and  related  expenses,  state  Blue  Sky
qualification   fees,  charges  of  the  custodian  and  transfer  and  dividend
disbursing agents, outside auditing,  accounting,  and legal services,  investor
servicing  fees and  expenses,  charges  for the  printing of  prospectuses  and
statements of additional information for regulatory purposes or for distribution
to  shareholders,  certain  shareholder  report charges and charges  relating to
corporate matters are borne by the Portfolio.

         Each of the Management  Contracts and the  Administration  Agreement is
subject to annual approval (commencing in 1996 for Mentor Intermediate  Duration
Portfolio,  Mentor Fixed-Income Portfolio,  and Mentor Cash Management Portfolio
and commencing in 1997 for Mentor  International  Portfolio) by (i) the Trustees
or (ii) vote of a  majority  (as  defined  in the 1940  Act) of the  outstanding
voting securities of the affected  Portfolio,  provided that in either event the
continuance  is  also  approved  by a  majority  of the  Trustees  who  are  not
"interested  persons" (as defined in the 1940 Act) of the Trust,  the investment
adviser in question,  or Mentor,  by vote cast in person at a meeting called for
the purpose of voting on such approval.  The Management Contracts are terminable
without  penalty,  on not more than sixty days'  notice and not less than thirty
days'  notice,  by the  Trustees,  by vote of the  holders of a majority  of the
affected  Portfolio's shares, or by the investment  adviser.  The Administration
Agreement  is  terminable  without  penalty,  immediately  upon  notice,  by the
Trustees  or by vote of the holders of a majority  of the  affected  Portfolio's
shares,  and on not  less  than  thirty  days'  notice  by  Mentor.  Each of the
Agreements will terminate automatically in the event of its assignment.

                                    BROKERAGE

         Transactions on U.S. stock exchanges,  commodities markets, and futures
markets and other  agency  transactions  involve  the payment by a Portfolio  of
negotiated brokerage commissions. Such commissions vary among different brokers.
A particular broker may charge different  commissions  according to such factors
as  the  difficulty  and  size  of  the  transaction.  Transactions  in  foreign
investments often involve the payment of fixed brokerage commissions,  which may
be  higher  than  those in the  United  States.  There is  generally  no  stated
commission in the case of securities traded in the over-the-counter markets, but
the  price  paid  by  the  Portfolio  usually  includes  an  undisclosed  dealer
commission  or  mark-up.  In  underwritten  offerings,  the  price  paid  by the
Portfolio  includes a disclosed,  fixed  commission or discount  retained by the
underwriter  or  dealer.  It is  anticipated  that most  purchases  and sales of
portfolio  securities by Portfolios  investing primarily in certain fixed-income
securities  will be with the issuer or with  underwriters of or dealers in those
securities,  acting  as  principal.  Accordingly,  those  Portfolios  would  not
ordinarily  pay  significant  brokerage  commissions  with respect to securities
transactions.

         It has for many years been a common practice in the investment advisory
business for advisers of investment companies and other institutional  investors
to receive brokerage and



<PAGE>



research services (as defined in the Securities Exchange Act of 1934, as amended
(the "1934 Act")), from  broker-dealers that execute portfolio  transactions for
the  clients  of  such   advisers  and  from  third   parties  with  which  such
broker-dealers have arrangements.  Consistent with this practice, the investment
advisers receive brokerage and research services and other similar services from
many broker-dealers with which they place the Portfolios' portfolio transactions
and from third parties with which these broker-dealers have arrangements.  These
services include such matters as general  economic and market reviews,  industry
and company  reviews,  evaluations  of  investments,  recommendations  as to the
purchase  and sale of  investments,  newspapers,  magazines,  pricing  services,
quotation  services,  news  services  and  personal  computers  utilized  by the
investment advisers' managers and analysts. Where the services referred to above
are not used  exclusively by an investment  adviser for research  purposes,  the
investment  adviser,  based upon its own allocations of expected use, bears that
portion of the cost of these services which directly relates to its non-research
use.  Some of  these  services  are of value to an  investment  adviser  and its
affiliates  in  advising  various of its  clients  (including  the  Portfolios),
although  not all of  these  services  are  necessarily  useful  and of value in
managing the Portfolios.

         The  investment  advisers place all orders for the purchase and sale of
portfolio  investments  for the Portfolios and buy and sell  investments for the
Portfolios through a substantial  number of brokers and dealers.  The investment
advisers seek the best overall terms available for the Portfolios, except to the
extent they may be permitted to pay higher  brokerage  commissions  as described
below.  In doing so, an investment  adviser,  having in mind a Portfolio's  best
interests,  considers  all  factors  it  deems  relevant,  including,  by way of
illustration,  price, the size of the transaction,  the nature of the market for
the security or other  investment,  the amount of the commission,  the timing of
the  transaction  taking into account market prices and trends,  the reputation,
experience and financial stability of the broker-dealer involved and the quality
of service rendered by the broker-dealer in other transactions.

         As  permitted by Section  28(e) of the 1934 Act, and by the  Management
Contracts,   the  investment   advisers  may  cause  the  Portfolios  to  pay  a
broker-dealer  which provides  "brokerage and research  services" (as defined in
the 1934 Act) to them an amount of disclosed commission for effecting securities
transactions on stock exchanges and other  transactions  for the Portfolio on an
agency basis in excess of the commission which another  broker-dealer would have
charged for effecting that transaction.  The investment  advisers'  authority to
cause a Portfolio  to pay any such greater  commissions  is also subject to such
policies as the Trustees may adopt from time to time. The investment advisers do
not  currently  intend to cause a  Portfolio  to make such  payments.  It is the
position of the staff of the  Securities  and Exchange  Commission  that Section
28(e) does not apply to the payment of such greater  commissions  in "principal"
transactions.  Accordingly,  the investment advisers will use their best efforts
to obtain the best overall terms available with respect to such transactions, as
described above.





<PAGE>



         Consistent with the Rules of Fair Practice of the National  Association
of Securities  Dealers,  Inc. and subject to such other policies as the Trustees
may  determine,  the  investment  advisers  may  consider  sales of  shares of a
Portfolio  (and,  if permitted by law, of the other Mentor funds) as a factor in
the  selection  of  broker-dealers  to  execute  portfolio  transactions  for  a
Portfolio.

         The Trustees have determined that portfolio  transactions for the Trust
may be effected  through  Wheat.  The  Trustees  have adopted  certain  policies
incorporating  the  standards of Rule 17e-l issued by the SEC under the 1940 Act
which requires,  among other things,  that the commissions paid to Wheat must be
reasonable  and fair compared to the  commissions,  fees, or other  remuneration
received by other brokers in connection with comparable  transactions  involving
similar   securities  during  a  comparable  period  of  time.  Wheat  will  not
participate  in brokerage  commissions  given by a Portfolio to other brokers or
dealers.  Over-the-counter  purchases  and sales are  transacted  directly  with
principal  market  makers  except  in those  cases in which  better  prices  and
executions  may be  obtained  elsewhere.  A  Portfolio  will in no event  effect
principal transactions with Wheat in over-the-counter  securities in which Wheat
makes a market.

         Under rules adopted by the SEC, Wheat may not execute  transactions for
a Portfolio on the floor of any  national  securities  exchange,  but may effect
transactions for a Portfolio by transmitting  orders for execution and arranging
for the  performance  of this function by members of the exchange not associated
with  Wheat.  Wheat  will be  required  to pay fees  charged  to  those  persons
performing the floor  brokerage  elements out of the brokerage  compensation  it
receives  from a  Portfolio.  The Trust has been  advised  by Wheat that on most
transactions,  the floor brokerage generally  constitutes from 5% and 10% of the
total commissions paid.

                        DETERMINATION OF NET ASSET VALUE

         The Trust  determines net asset value per share of the Portfolios  each
day the New  York  Stock  Exchange  (the  "Exchange")  is open.  Currently,  the
Exchange is closed Saturdays,  Sundays,  and the following holidays:  New Year's
Day, Presidents' Day, Good Friday,  Memorial Day, the Fourth of July, Labor Day,
Thanksgiving, and Christmas.

         MENTOR INTERMEDIATE DURATION PORTFOLIO,  MENTOR FIXED-INCOME  PORTFOLIO
AND MENTOR INTERNATIONAL  PORTFOLIO.  In respect of Mentor Intermediate Duration
Portfolio,  Mentor FixedIncome  Portfolio,  and Mentor International  Portfolio,
securities  for which  market  quotations  are readily  available  are valued at
prices  which,  in the  opinion  of the  Trustees  or a  Portfolio's  investment
adviser, most nearly represent the market values of such securities.  Currently,
such prices are  determined  using the last  reported sale price or, if no sales
are reported (as in the case of some securities  traded  over-the-counter),  the
last  reported bid price,  except that certain U.S.  Government  securities  are
stated at the mean between the last  reported bid and asked  prices.  Short-term
investments  having  remaining  maturities  of 60  days or less  are  stated  at
amortized cost, which approximates market value. All other securities and assets
are valued at their fair value  following  procedures  approved by the Trustees.
Liabilities are deducted from the total,  and the resulting amount is divided by
the number of shares of the Portfolio outstanding.

         Reliable market  quotations are not considered to be readily  available
for long-term  corporate bonds and notes,  certain preferred stocks,  tax-exempt
securities, or certain foreign securities.  These investments are stated at fair
value on the basis of valuations  furnished by pricing services  approved by the
Trustees, which determine valuations for normal, institutionalsize trading units
of such  securities  using methods based on market  transactions  for comparable
securities  and various  relationships  between  securities  which are generally
recognized by institutional traders.

         If any securities held by a Portfolio are restricted as to resale,  its
investment  adviser  determines  their  fair  values.  The  fair  value  of such
securities  is  generally  determined  as the  amount  which a  Portfolio  could
reasonably expect to realize from an orderly disposition of such securities over
a reasonable  period of time. The valuation  procedures  applied in any specific
instance  are  likely  to vary  from  case to case.  However,  consideration  is
generally  given to the financial  position of the issuer and other  fundamental
analytical data relating to the investment and to the nature of the restrictions
on disposition of the securities (including any registration expenses that might
be borne by the Portfolio in connection with such disposition). In addition,




<PAGE>



specific  factors  are  also  generally  considered,  such  as the  cost  of the
investment,  the market value of any  unrestricted  securities of the same class
(both at the time of  purchase  and at the time of  valuation),  the size of the
holding,  the prices of any recent  transactions  or offers with respect to such
securities and any available analysts' reports regarding the issuer.

         Generally,  trading in certain securities (such as foreign  securities)
is  substantially  completed each day at various times prior to the close of the
Exchange. The values of these securities used in determining the net asset value
of a  Portfolio's  shares are  computed as of such times.  Also,  because of the
amount of time required to collect and process  trading  information as to large
numbers  of  securities  issues,  the  values  of  certain  securities  (such as
convertible bonds, U.S. Government  securities,  and tax-exempt  securities) are
determined based on market quotations collected earlier in the day at the latest
practicable  time  prior to the  close  of the  Exchange.  Occasionally,  events
affecting  the value of such  securities  may occur  between  such times and the
close of the  Exchange  which  will not be  reflected  in the  computation  of a
Portfolio's  net asset value. If events  materially  affecting the value of such
securities  occur during such period,  then these  securities  will be valued at
their fair value following procedures approved by the Trustees.

         MENTOR CASH  MANAGEMENT  PORTFOLIO  ONLY.  The valuation of Mentor Cash
Management  Portfolio's  portfolio  securities is based upon its amortized cost,
which does not take into account  unrealized  securities  gains or losses.  This
method  involves  initially  valuing an  instrument  at its cost and  thereafter
assuming a  constant  amortization  to  maturity  of any  discount  or  premium,
regardless of the impact of  fluctuating  interest  rates on the market value of
the  instrument.  By using  amortized  cost  valuation,  the Portfolio  seeks to
maintain a constant net asset value of $1.00 per share,  despite minor shifts in
the  market  value of its  portfolio  securities.  While  this  method  provides
certainty  in  valuation,  it may  result in  periods  during  which  value,  as
determined  by amortized  cost,  is higher or lower than the price the Portfolio
would receive if it sold the  instrument.  During periods of declining  interest
rates,  the quoted yield on shares of the Portfolio may tend to be higher than a
like computation made by a fund with identical investments utilizing a method of
valuation  based on market  prices and estimates of market prices for all of its
portfolio  instruments.  Thus,  if the use of  amortized  cost by the  Portfolio
resulted in a lower aggregate portfolio value on a particular day, a prospective
investor in the Portfolio  would be able to obtain a somewhat higher yield if he
purchased shares of the Portfolio on that day, than would result from investment
in a  fund  utilizing  solely  market  values,  and  existing  investors  in the
Portfolio  would receive less investment  income.  The converse would apply on a
day  when  the use of  amortized  cost by the  Portfolio  resulted  in a  higher
aggregate portfolio value. However, as a result of certain procedures adopted by
the Trust, the Trust believes any difference will normally be minimal.

         The valuation of the  Portfolio's  portfolio  instruments  at amortized
cost is permitted in accordance  with  Securities and Exchange  Commission  Rule
2a-7 and certain procedures adopted by the Trustees.  Under these procedures,  a
Portfolio must maintain a dollar-weighted average




<PAGE>



portfolio  maturity  of 90  days  or  less,  purchase  only  instruments  having
remaining maturities of 397 days or less, and invest in securities determined by
the Trustees to be of high quality with minimal credit risks.  The Trustees have
also  established  procedures  designed to stabilize,  to the extent  reasonably
possible,  the  Portfolio's  price  per share as  computed  for the  purpose  of
distribution,  redemption  and  repurchase at $1.00.  These  procedures  include
review of the Portfolio's  portfolio holdings by the Trustees, at such intervals
as they may deem appropriate, to determine whether a Portfolio's net asset value
calculated by using readily available market quotations  deviates from $1.00 per
share,  and, if so, whether such deviation may result in material dilution or is
otherwise unfair to existing  shareholders.  In the event the Trustees determine
that such a deviation may result in material  dilution or is otherwise unfair to
existing  shareholders,  they will take such corrective action as they regard as
necessary and appropriate,  including the sale of portfolio instruments prior to
maturity to realize capital gains or losses or to shorten the average  portfolio
maturity; withholding dividends; redemption of shares in kind; or establishing a
net asset value per share by using readily available market quotations.

         Since the net income of the  Portfolio  is declared as a dividend  each
time it is determined, the net asset value per share of the Portfolio remains at
$1.00 per share immediately after such  determination and dividend  declaration.
Any  increase  in the  value  of a  shareholder's  investment  in the  Portfolio
representing  the reinvestment of dividend income is reflected by an increase in
the number of shares of the Portfolio in the  shareholder's  account on the last
day of each month (or, if that day is not a business  day, on the next  business
day). It is expected that the  Portfolio's net income will be positive each time
it is determined.  However,  if because of realized losses on sales of portfolio
investments,  a sudden rise in interest  rates,  or for any other reason the net
income  of the  Portfolio  determined  at any  time is a  negative  amount,  the
Portfolio will offset such amount allocable to each then  shareholder's  account
from dividends accrued during the month with respect to such account.  If at the
time of payment of a dividend by the  Portfolio  (either at the regular  monthly
dividend  payment date, or, in the case of a shareholder  who is withdrawing all
or  substantially  all of the shares in an account,  at the time of withdrawal),
such negative amount exceeds a shareholder's  accrued  dividends,  the Portfolio
will reduce the number of  outstanding  shares by treating  the  shareholder  as
having  contributed  to the  capital of the  Portfolio  that  number of full and
fractional shares which represent the amount of the excess.  Each shareholder is
deemed  to have  agreed  to such  contribution  in  these  circumstances  by its
investment in the Portfolio.

         Should the  Portfolio  incur or  anticipate  any unusual or  unexpected
significant   expense  or  loss  which  would  affect   disproportionately   the
Portfolio's  income for a particular  period,  the  Trustees  would at that time
consider  whether to adhere to the dividend policy  described above or to revise
it in light of the then prevailing  circumstances  in order to ameliorate to the
extent  possible  the  disproportionate  effect of such  expense or loss on then
existing  shareholders.  Such  expenses or losses may  nevertheless  result in a
shareholder's  receiving no dividends for the period during which the shares are
held and receiving  upon  redemption a price per share lower than that which was
paid.

                                   TAX STATUS

         Each Portfolio  intends to qualify each year and elect to be taxed as a
regulated  investment  company under  Subchapter M of the United States Internal
Revenue Code of 1986, as amended (the "Code").

         As a regulated  investment company qualifying to have its tax liability
determined under Subchapter M, a Portfolio will not be subject to federal income
tax on any of its net investment  income or net realized  capital gains that are
distributed to  shareholders.  As a series of  Massachusetts  business  trust, a
Portfolio will not under present law be subject to any excise or income taxes in
Massachusetts.

         In order to qualify as a  "regulated  investment  company," a Portfolio
must,  among  other  things,  (a) derive at least 90% of its gross  income  from
dividends,  interest,  payments with respect to securities loans, gains from the
sale or other  dispositions of stock,  securities,  or foreign  currencies,  and
other income  (including  gains from  options,  futures,  or forward  contracts)
derived with respect to its business of investing in such stock, securities,  or
currencies;  (b) derive less than 30% of its gross income from the sale or other
disposition of certain assets  (including  stock and securities)  held less than
three  months;  (c) 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,  and other securities limited
generally with respect to any one issuer to not more than 5% of the total assets
of the Portfolio and not more than 10% of the outstanding  voting  securities of
such  issuer,  and (ii) not more than 25% of the value of its assets is invested
in the  securities of any issuer  (other than U.S.  Government  Securities).  In
order to receive the  favorable  tax  treatment  accorded  regulated  investment
companies  and  their  shareholders,  moreover,  a  Portfolio  must  in  general
distribute at least 90% of its interest, dividends, net short-term capital gain,
and certain other income each year.

         An excise tax at the rate of 4% will be imposed on the excess,  if any,
of each Portfolio's "required distribution" over its actual distributions in any
calendar year. Generally,  the "required distribution" is 98% of the Portfolio's
ordinary  income for the  calendar  year plus 98% of its capital gain net income
recognized  during the one-year  period ending on October 31 (or December 31, if
the  Portfolio so elects)  plus  undistributed  amounts  from prior years.  Each
Portfolio  intends to make  distributions  sufficient to avoid imposition of the
excise tax. Distributions  declared by a Portfolio during October,  November, or
December to  shareholders  of record on a date in any such month and paid by the
Portfolio during the following  January will be treated for federal tax purposes
as paid by the Portfolio and received by shareholders on December 31 of the year
in which declared.

         Under federal income tax law, a portion of the  difference  between the
purchase price of  zero-coupon  securities in which a Portfolio has invested and
their face value  ("original  issue discount") is considered to be income to the
Portfolio each year, even though the Portfolio will




<PAGE>



not receive cash interest  payments from these  securities.  This original issue
discount  (imputed income) will comprise a part of the net investment  income of
the Portfolio which must be distributed to shareholders in order to maintain the
qualification  of the Portfolio as a regulated  investment  company and to avoid
federal income tax at the level of the Portfolio.

         Each Portfolio is required to withhold 31% of all income  dividends and
capital gain distributions,  and 31% of the gross proceeds of all redemptions of
Portfolio  shares, in the case of any shareholder who does not provide a correct
taxpayer  identification  number,  about whom a Portfolio  is notified  that the
shareholder  has under reported income in the past, or who fails to certify to a
Portfolio that the  shareholder is not subject to such  withholding.  Tax-exempt
shareholders are not subject to these back-up  withholding rules so long as they
furnish the Portfolio with a proper certification.

         Foreign    currency-denominated    securities   and   related   hedging
transactions  (Mentor   International   Portfolio  only).  Mentor  International
Portfolio's  transactions in foreign  currencies,  foreign  currency-denominated
debt securities,  and certain foreign currency options,  futures contracts,  and
forward contracts (and similar  instruments) may give rise to ordinary income or
loss to the extent such income or loss results from fluctuations in the value of
the foreign currency concerned.

         If more than 50% of the Portfolio's  assets at year end consists of the
debt and equity securities of foreign  corporations,  the Portfolio may elect to
permit  shareholders  to claim a credit or deduction on their income tax returns
for their pro rata portion of qualified  taxes paid by the  Portfolio to foreign
countries.  In such a case,  shareholders  will  include  in gross  income  from
foreign sources their pro rata shares of such taxes. A shareholder's  ability to
claim a foreign tax credit or deduction in respect of foreign  taxes paid by the
Portfolio may be subject to certain limitations imposed by the Code, as a result
of which a shareholder  may not get a full credit or deduction for the amount of
such taxes.  Shareholders who do not itemize on their federal income tax returns
may claim a credit (but no deduction) for such foreign taxes.

         Investment  by the  Portfolio in certain  "passive  foreign  investment
companies"  could  subject the Portfolio to a U.S.  federal  income tax or other
charge  on the  proceeds  from the  sale of its  investment  in such a  company;
however,  this tax can be avoided by making an election to mark such investments
to market  annually  or to treat the  passive  foreign  investment  company as a
"qualified electing fund."

         The foregoing is a general and  abbreviated  summary of the  applicable
provisions  of the Code and related  regulations  currently  in effect.  For the
complete provisions, reference should be made to the pertinent Code sections and
regulations.  The Code and  regulations  are subject to change by legislative or
administrative actions. Dividends and distributions also may be subject to state
and  federal  taxes.  Shareholders  are  urged to  consult  their  tax  advisers
regarding specific questions as to federal,  state or local taxes. The foregoing
discussion relates solely to U.S.




<PAGE>



federal income tax law.  Non-U.S. investors should consult their tax advisers
concerning the tax consequences of ownership of shares of the Portfolio,
including the possibility that distributions may be subject to a 30% United
States withholding tax (or a reduced rate of withholding provided by treaty).

                             PERFORMANCE INFORMATION
   
         MENTOR   INTERMEDIATE   DURATION  PORTFOLIO  AND  MENTOR   FIXED-INCOME
PORTFOLIO. With respect to Mentor Intermediate Duration Portfolio,  Mentor Fixed
Income Portfolio and Mentor International Portfolios, total return is determined
by  calculating  the  actual  investment  return on a $1,000  investment  in the
Portfolio  over the  applicable  period.  Total return may also be presented for
other periods.  Total return  calculations  assume reinvestment of all Portfolio
distributions  at net asset value on their  respective  reinvestment  dates. The
cumulative total return for the life of Mentor  Intermediate  Duration Portfolio
(commencement of operations December 19, 1994) and Mentor Fixed-Income Portfolio
(commencement of operations  December 6, 1994) through October 31, 1995 was
12.38% and  15.90%,  respectively.  NO  SHARES OF  MENTOR  INTERNATIONAL
PORTFOLIO  WERE OUTSTANDING DURING THIS PERIOD.
    
         Each Portfolio's  yield is presented for a specified  thirty-day period
(the "base period").  Yield is based on the amount determined by (i) calculating
the aggregate  amount of dividends and interest earned by a Portfolio during the
base period less expenses accrued for that period, and (ii) dividing that amount
by the product of (A) the average daily number of shares of the




<PAGE>


   
Portfolio  outstanding  during the base period and entitled to receive dividends
and (B) the net asset  value per share on the last day of the base  period.  The
result is  annualized on a  compounding  basis to determine the yield.  For this
calculation,  interest  earned  on  debt  obligations  held  by a  Portfolio  is
generally  calculated  using the yield to maturity (or first expected call date)
of  such  obligations  based  on  their  market  values  (or,  in  the  case  of
receivables-backed  securities  such as  GNMA's,  based on cost).  Dividends  on
equity  securities are accrued daily at their stated dividend  rates.  The yield
for Mentor  Intermediate  Duration  and Mentor  Fixed-Income  Portfolio  for the
thirty-day  period ended  October 31, 1995 was 6.30% and 6.36%,  respectively.
NO SHARES OF MENTOR INTERNATIONAL PORTFOLIO WERE OUTSTANDING DURING THIS PERIOD.
    
         MENTOR  CASH  MANAGEMENT  PORTFOLIO  ONLY.  The  yield of  Mentor  Cash
Management  Portfolio  is computed by  determining  the  percentage  net change,
excluding  capital  changes,  in the value of an  investment in one share of the
Portfolio  over the base  period,  and  multiplying  the net change by 365/7 (or
approximately   52  weeks).   The  Portfolio's   effective  yield  represents  a
compounding of the yield by adding 1 to the number  representing  the percentage
change in value of the investment during the base period,  raising that sum to a
power equal to 365/7, and subtracting 1 from the result.
   
         Based on the  seven-day  period  ended  October 31,  1995,  Mentor Cash
Management Portfolio's yield was 5.79% and its effective yield was 5.96%.
    


         ALL DATA FOR EACH OF THE PORTFOLIOS ARE BASED ON PAST  PERFORMANCE  AND
DO NOT PREDICT FUTURE RESULTS.

         Independent  statistical  agencies  measure  a  Portfolio's  investment
performance and publish comparative  information showing how the Portfolio,  and
other investment companies,  performed in specified time periods. Agencies whose
reports are commonly used for such comparisons are set forth below. From time to
time, a Portfolio may distribute  these  comparisons to its  shareholders  or to
potential investors.  THE AGENCIES LISTED BELOW MEASURE PERFORMANCE BASED ON THE
BASIS  OF THEIR  OWN  CRITERIA  RATHER  THAN ON THE  BASIS  OF THE  STANDARDIZED
PERFORMANCE MEASURES DESCRIBED ABOVE.

         reinvestment of capital gains and income dividends. They do not reflect
         deduction  of any sales  charges.  Lipper  rankings  cover a variety of
         performance  periods,  for example  year-to-date,  1-year,  5-year, and
         10-year  performance.  Lipper  classifies  mutual  funds by  investment
         objective and asset category.

         MORNINGSTAR,  INC.  distributes  mutual fund ratings twice a month. the
         ratings are divided into five groups: highest, above average,  neutral,
         below  average  and  lowest.   They   represent  a  fund's   historical
         risk/reward ratio relative to other funds with similar objectives.  The
         performance factor is a weighted-average  assessment of the Portfolio's
         3-year,  5-year,  and 10-year total return  performance (if available)
         reflecting  deduction of expenses  and sales  charges.  Performance  is
         adjusted using  quantitative  techniques to reflect the risk profile of
         the fund.  The ratings are derived  from a purely  quantitative  system
         that does not utilize the subjective criteria  customarily  employed by
         rating  agencies  such as  Standard & Poor's  Corporation  and  Moody's
         Investor Service, Inc.

         WEISENBERGER'S MANAGEMENT RESULTS publishes mutual fund rankings and is
         distributed  monthly.  The rankings are based  entirely on total return
         calculated by Weisenberger  for periods such as  year-to-date,  1-year,
         3-year,  5-year and  10-year  performance.  Mutual  funds are ranked in
         general categories (e.g.,  international  bond,  international  equity,
         municipal bond, and maximum capital gain). Weisenberger rankings do not
         reflect deduction of sales charges or fees.

         Independent  publications may also evaluate a Portfolio's  performance.
Certain  of those  publications  are  listed  below,  at the  request  of Mentor
Distributors, which bears full responsibility for their use and the descriptions
appearing  below.  From time to time any or all of the Portfolios may distribute
evaluations by or excerpts from these  publications  to its  shareholders  or to
potential investors. The following illustrates the types of information provided
by these publications.

         BUSINESS WEEK publishes mutual fund rankings in its Investment  Figures
         of the Week column.  The rankings are based on 4-week and 52-week total
         return  reflecting  changes in net asset value and the  reinvestment of
         all distributions.  They do not reflect deduction of any sales charges.
         Portfolios  are not  categorized;  they compete in a large  universe of
         over  2,000  funds.  The  source  for  rankings  is data  generated  by
         Morningstar, Inc.

         INVESTOR'S  BUSINESS  DAILY  publishes  mutual fund rankings on a daily
         basis.  The  rankings  are  depicted  as the  top 25  funds  in a given
         category.  The categories are based loosely on the type of fund,  e.g.,
         growth funds, balanced funds, U.S. government funds, GNMA funds, growth
         and income funds,  corporate bond funds, etc.  Performance  periods for
         sector  equity  funds can vary  from 4 weeks to 39  weeks;  performance
         periods for other fund groups vary from 1 year to 3 years. Total return
         performance  reflects  changes in net asset value and  reinvestment  of
         dividends and capital  gains.  The rankings are based strictly on total
         return.  They do not reflect deduction of any sales charges Performance
         grades are conferred from A+ to E. An A+ rating means that the fund has
         performed  within the top 5% of a general  universe of over 2000 funds;
         an A rating denotes the top 10%; an A- is given to the top 15%, etc.

         BARRON'S periodically  publishes mutual fund rankings. The rankings are
         based  on  total  return  performance  provided  by  Lipper  Analytical
         Services.  The Lipper total return data  reflects  changes in net asset
         value and reinvestment of distributions, but does not reflect deduction
         of any sales  charges.  The  performance  periods vary from  short-term
         intervals  (current quarter or year-to-date,  for example) to long-term
         periods  (five-year or ten-year  performance,  for  example).  Barron's
         classifies the funds using the Lipper mutual fund  categories,  such as
         Capital  Appreciation  Portfolios,  Growth Portfolios,  U.S. Government
         Portfolios,   Equity  Income  Portfolios,   Global   Portfolios,   etc.
         Occasionally,  Barron's modifies the Lipper  information by ranking the
         funds in asset  classes.  "Large  funds"  may be those  with  assets in
         excess of $25  million;  "small  funds" may be those with less than $25
         million in assets.

         THE WALL STREET JOURNAL  publishes its Mutual Portfolio  Scorecard on a
         daily basis. Each Scorecard is a ranking of the top-15 funds in a given
         Lipper Analytical Services category. Lipper provides the rankings based
         on its total  return  data  reflecting  changes in net asset  value and
         reinvestment of distributions and not reflecting any sales charges. The
         Scorecard   portrays   4-week,   year-to-date,   one-year   and  5-year
         performance; however, the ranking is based on the one-year results. The
         rankings for any given category appear approximately once per month.

         FORTUNE magazine periodically  publishes mutual fund rankings that have
         been  compiled for the magazine by  Morningstar,  Inc.  Portfolios  are
         placed in stock or bond fund categories (for example, aggressive growth
         stock funds,  growth stock funds,  small company stock funds, junk bond
         funds,  Treasury bond funds etc.),  with the top-10 stock funds and the
         top-5 bond funds  appearing in the rankings.  The rankings are based on
         3- year annualized total return  reflecting  changes in net asset value
         and  reinvestment of  distributions  and not reflecting  sales charges.
         Performance  is adjusted using  quantitative  techniques to reflect the
         risk profile of the fund.

         MONEY  magazine  periodically  publishes  mutual  fund  rankings  on  a
         database  of  funds  tracked  for  performance  by  Lipper   Analytical
         Services.  The funds are placed in 23 stock or bond fund categories and
         analyzed for five-year  risk  adjusted  return.  Total return  reflects
         changes  in net  asset  value and  reinvestment  of all  dividends  and
         capital gains distributions and does not reflect deduction of any sales
         charges.  Grades  are  conferred  (from  A to E):  the  top 20% in each
         category receive an A, the next 20% a B, etc. To be ranked, a fund must
         be at least one year old,  accept a minimum  investment  of  $25,000 or
         less and have had assets of at least $25 million as of a given date.

         FINANCIAL WORLD publishes its monthly Independent  Appraisals of Mutual
         Portfolios, a survey of approximately 1000 mutual funds. Portfolios are
         categorized as to type,  e.g.,  balanced  funds,  corporate bond funds,
         global bond funds, growth and income funds, U.S. government bond funds,
         etc. To compete, funds must be over one year old, have over $1




<PAGE>



         million in assets, require a maximum of $10,000 initial investment, and
         should be  available  in at least 10 states in the United  States.  The
         funds receive a composite  past  performance  rating,  which weighs the
         intermediate - and long-term  past  performance of each fund versus its
         category,  as well as taking into account its risk, reward to risk, and
         fees. An A+ rated fund is one of the best, while a D- rated fund is one
         of the worst.  The  source for  Financial  World  rating is  Schabacker
         investment management in Rockville, Maryland.

         FORBES  magazine  periodically  publishes  mutual fund ratings based on
         performance  over at least two bull and bear market  cycles.  The funds
         are categorized by type,  including  stock and balanced funds,  taxable
         bond funds,  municipal  bond funds,  etc. Data sources  include  Lipper
         Analytical  Services and CDA Investment  Technologies.  The ratings are
         based strictly on performance at net asset value over the given cycles.
         Portfolios  performing in the top 5% receive an A+ rating;  the top 15%
         receive an A rating; and so on until the bottom 5% receive an F rating.
         Each fund exhibits two ratings, one for performance in "up" markets and
         another for performance in "down" markets.

         KIPLINGER'S   PERSONAL  FINANCE  MAGAZINE  (formerly  Changing  Times),
         periodically  publishes  rankings of mutual funds based on one-, three-
         and five-year total return performance  reflecting changes in net asset
         value  and   reinvestment  of  dividends  and  capital  gains  and  not
         reflecting  deduction of any sales  charges.  Portfolios  are ranked by
         tenths:  a rank of 1 means  that a fund was  among the  highest  10% in
         total  return  for the  period;  a rank of 10 denotes  the bottom  10%.
         Portfolios  compete in categories of similar funds -- aggressive growth
         funds,  growth and income funds,  sector funds,  corporate  bond funds,
         global governmental bond funds,  mortgage-backed securities funds, etc.
         Kiplinger's  also  provides a  risk-adjusted  grade in both  rising and
         falling  markets.  Portfolios  are graded  against others with the same
         objective.   The  average   weekly  total  return  over  two  years  is
         calculated.  Performance is adjusted using  quantitative  techniques to
         reflect the risk profile of the fund.

         U.S. NEWS AND WORLD REPORT periodically  publishes mutual fund rankings
         based on an overall  performance  index  (OPI)  devised by Kanon  Bloch
         Carre & Co., a Boston  research  firm.  Over 2000 funds are tracked and
         divided  into 10 equity,  taxable bond and  tax-free  bond  categories.
         Portfolios compete within the 10 groups and three broad categories. The
         OPI is a number from 0-100 that  measures the relative  performance  of
         funds at least  three  years old over the last 1, 3, 5 and 10 years and
         the last six bear markets.  Total return reflects  changes in net asset
         value  and  the   reinvestment  of  any  dividends  and  capital  gains
         distributions  and does not  reflect  deduction  of any sales  charges.
         Results for the longer periods receive the most weight.

         THE 100 BEST MUTUAL PORTFOLIOS YOU CAN BUY (1992), authored by Gordon
         K. Williamson.  The author's list of funds is divided into 12 equity
         and bond fund categories,




<PAGE>



         and the 100 funds are  determined  by applying  four  criteria.  First,
         equity funds whose current management teams have been in place for less
         than five years are  eliminated.  (The standard for bond funds is three
         years.)  Second,  the author excludes any fund that ranks in the bottom
         20  percent  of its  category's  risk  level.  Risk  is  determined  by
         analyzing  how  many  months  over the past  three  years  the fund has
         underperformed  a bank CD or a U.S.  Treasury bill.  Third, a fund must
         have demonstrated  strong results for current  three-year and five-year
         performance.  Fourth, the fund must either possess, in Mr. Williamson's
         judgment,  "excellent"  risk-adjusted  return or "superior" return with
         low levels of risk. Each of the 100 funds is ranked in five categories:
         total return, risk/volatility, management, current income and expenses.
         The rankings follow a fivepoint  system:  zero designates  "poor";  one
         point means "fair"; two points denote "good"; three points qualify as a
         "very  good";  four  points  rank as  "superior";  and five points mean
         "excellent."

                              SHAREHOLDER LIABILITY

         Under   Massachusetts   law,    shareholders   could,   under   certain
circumstances,  be held  personally  liable  for the  obligations  of the Trust.
However, the Agreement and 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 Agreement and  Declaration  of Trust provides
for  indemnification  out of a Portfolio's  property for all loss and expense of
any shareholder held personally liable for the obligations of a Portfolio.  Thus
the risk of a shareholder's  incurring  financial loss on account of shareholder
liability is limited to  circumstances in which the Portfolio would be unable to
meet its obligations.

                                     RATINGS

         The rating services' descriptions of corporate bonds are:

MOODY'S INVESTORS SERVICE, INC.:

AAA -- Bonds  which  are rated Aaa are  judged to be of the best  quality.  They
carry the smallest  degree of investment  risk and are generally  referred to as
"gilt-edge".  Interest  payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change,  such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

AA --  Bonds  which  are  rated  Aa are  judged  to be of  high  quality  by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds.  They are rated lower than the best bonds  because  margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements  may be of greater  amplitude  or there may be other  elements  present
which make the long term risks appear somewhat larger than in Aaa securities.

A -- Bonds which are rated A possess many  favorable  investment  attributes and
are to be considered as upper medium grade obligations.  Factors giving security
to principal  and interest are  considered  adequate but elements may be present
which suggest a susceptibility to impairment sometime in the future.

BAA -- Bonds which are rated Baa are  considered  as medium  grade  obligations,
i.e., they are neither highly  protected nor poorly secured.  Interest  payments
and principal  security appear adequate for the present,  but certain protective
elements may be lacking or may be  characteristically  unreliable over any great
length of time. Such bonds lack outstanding  investment  characteristics  and in
fact have speculative characteristics as well.

   
STANDARD & POOR'S:
    

AAA -- Bonds  rated AAA have the highest  rating  assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.

AA -- Bonds  rated AA have a very  strong  capacity  to pay  interest  and repay
principal and differ from the highest rated issues only in small degree.

A -- Bonds rated A have a strong  capacity to pay interest  and repay  principal
although they are somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than bonds in higher rated categories.




<PAGE>



BBB -- Bonds  rated  BBB are  regarded  as having an  adequate  capacity  to pay
interest and repay principal.  Whereas they normally exhibit adequate protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened  capacity to pay interest and repay  principal  for
bonds in this category than for bonds in higher rated categories.

A-1 AND PRIME-1 COMMERCIAL PAPER RATINGS

The rating A-1 (including A-1+) is the highest  commercial paper rating assigned
by S&P. Commercial paper rated A-1 by S&P has the following characteristics:

  (BULLET)         liquidity ratios are adequate to meet cash requirements;

  (BULLET)         long-term senior debt is rated "A" or better;

  (BULLET)         the issuer has access to at least two additional channels of
                   borrowing;

  (BULLET)         basic earnings and cash flow have an upward trend with
                   allowance made for unusual circumstances;

  (BULLET)         typically, the issuer's industry is well established and the
                   issuer has a strong position within the industry; and

  (BULLET)         the reliability and quality of management are unquestioned.

Relative  strength  or  weakness  of the above  factors  determines  whether the
issuer's  commercial  paper is rated A-1, A-2 or A-3.  Issues rated A-1 that are
determined by S&P to have  overwhelming  safety  characteristics  are designated
A-1+.

The rating Prime-1 is the highest  commercial  paper rating assigned by Moody's.
Among the factors considered by Moody's in assigning ratings are the following:

  (BULLET)         evaluation of the management of the issuer;

  (BULLET)         economic evaluation of the issuer's industry or industries
                   and an appraisal of speculative-type risks which may be
                   inherent in certain areas;

  (BULLET)         evaluation of the issuer's products in relation to
                   competition and customer acceptance;

  (BULLET)         liquidity;

  (BULLET)         amount and quality of long-term debt;



<PAGE>



  (BULLET)        trend of earnings over a period of ten years;

  (BULLET)        financial strength of parent company and the relationships
                  which exist with the issuer; and

  (BULLET)        recognition  by the  management  of  obligations  which may be
                  present or may arise as a result of public interest  questions
                  and preparations to meet such obligations.

MENTOR INSTITUTIONAL TRUST
NOTES TO FINANCIAL STATEMENTS
OCTOBER 31, 1995

NOTE 1: ORGANIZATION
Mentor Institutional Trust, formerly IMG Institutional Trust, was organized on
February 8, 1994, and is registered under the Investment Company Act of 1940, as
amended, as an open-end management investment company. On June 27, 1995, the
name of the the Trust was changed to Mentor Institutional Trust ("Trust"). The
Trust consists of four separate diversified portfolios (hereinafter each
individually referred to as a "Portfolio" or collectively as the "Portfolios")
at October 31, 1995. These financial statements include the following
Portfolios:

    Mentor Cash Management Portfolio
    ("Cash Management Portfolio")

    Mentor Intermediate Duration Portfolio
    ("Intermediate Duration Portfolio")

    Mentor Fixed-Income Portfolio
    ("Fixed-Income Portfolio")

The assets of each Portfolio of the Trust are segregated and a shareholder's
interest is limited to the Portfolio in which shares are held.

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES
The following is a summary of significant accounting policies consistently
followed by the Portfolios:

A. Valuation of Securities

Securities held by the Cash Management Portfolio are stated at amortized cost,
which approximates market value. In the event that a deviation of 1/2 of 1% or
more exists between the Portfolio's $1.00 per share net asset value, calculated
at amortized cost, and the net asset value calculated by reference to
market-based values, or if there is any other deviation that the Board of
Trustees believes would result in a material dilution to shareholders or
purchasers, the Board of Trustees will promptly consider what action should be
initiated.

U.S. Government obligations held by the Intermediate Duration Portfolio and the
Fixed-Income Portfolio are valued at the mean between the over-the-counter bid
and asked prices as furnished by an independent pricing service. Listed
corporate bonds, other fixed income

                                       15

<PAGE>

securities, mortgage backed securities, mortgage related and other related
securities are valued at the prices provided by an independent pricing service.
Security valuations not available from an independent pricing service are
provided by dealers reviewed by the Board of Trustees. In determining value, the
dealers use information with respect to transactions in such securities, market
transactions in comparable securities, various relationships between securities,
and yield to maturity. Any securities for which current market quotations are
not readily available are valued at their fair value as determined in good faith
under procedures established by the Board of Trustees.

B. Repurchase Agreements

It is the policy of the Trust to require the custodian bank to take possession,
to have legally segregated in the Federal Reserve Book entry system, or to have
segregated within the custodian bank's possession all securities held as
collateral in support of repurchase agreement investments. Additionally,
procedures have been established by the Trust to monitor, on a daily basis, the
market value of each repurchase agreement's underlying securities to ensure the
existence of a proper level of collateral.

The Trust will only enter into repurchase agreements with banks and other
recognized financial institutions such as broker/dealers which are deemed by the
Trust's adviser to be creditworthy pursuant to guidelines established by the
Trustees. Risks may arise from the potential inability of counterparties to
honor the terms of the repurchase agreement. Accordingly, the Trust could
receive less than the repurchase price on the sale of collateral securities.

C. Security Transactions and Interest Income

Security transactions for the Portfolios are accounted for on a trade date
basis. Interest income is recorded on the accrual basis and includes
amortization of premium and discount on investments. Realized and unrealized
gains and losses on investment security transactions are calculated on an
identified cost basis.

                                       16

<PAGE>


D. Expenses

Expenses arising in connection with a Portfolio are allocated to that Portfolio.
Other Trust expenses are allocated among the Portfolios in proportion to their
relative net assets.

E. Federal Taxes

No provision for federal income taxes has been made since it is each Portfolio's
intent to comply with the provisions applicable to regulated investment
companies under the Internal Revenue Code and to distribute to its shareholders
within allowable time limit substantially all taxable income and realized
capital gains.

F. When-Issued and Delayed Delivery Transactions

The Fixed-Income Portfolio and Intermediate-Duration Portfolio may engage in
when-issued or delayed delivery transactions. To the extent the Portfolios
engage in such transactions, they will do so for the purpose of acquiring
portfolio securities consistent with their investment objectives and policies
and not for the purpose of investment leverage. The Portfolios will record a
when-issued security and the related liability on the trade date. Until the
securities are received and paid for, the Portfolios will maintain security
positions such that sufficient liquid assets will be available to make payment
for the securities purchased. Securities purchased on a when-issued or delayed
delivery basis are marked to market daily and begin earning interest on the
settlement date.

G. Deferred Expenses

Costs incurred by the Portfolios in connection with their initial share
registration and organization costs were deferred by the Portfolios and are
being amortized on a straight-line basis over a five-year period.

H. Distributions

Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles. These differences are primarily due to deferral of wash sales.

                                       17

<PAGE>


NOTE 3: DIVIDENDS
Dividends will be declared daily and paid monthly by the Cash Management
Portfolio. Dividends are declared and paid quarterly by the Fixed-Income
Portfolio and Intermediate Duration Portfolio. Capital gains realized by each
Portfolio, if any, will be distributed annually.

NOTE 4: INVESTMENT MANAGEMENT AND ADMINISTRATION AGREEMENTS
Each Portfolio has entered into an Investment Management Agreement with
Commonwealth Investment Counsel, Inc. ("Commonwealth") to provide investment
advisory services to each of the Portfolios. Commonwealth receives no
compensation for its services. Commonwealth is a wholly-owned subsidiary of
Mentor Investment Group, Inc. (formerly Investment Management Group, Inc.),
which is a wholly-owned subsidiary of Wheat First Butcher Singer, Inc.

In order to limit the annual operating expenses of the Portfolios, Commonwealth
may bear certain expenses incurred in connection with the operation of the
Portfolios. For the period ended October 31, 1995 Commonwealth bore expenses of
$63,607, $20,703 and $45,996 respectively, for the Cash Management Portfolio,
Intermediate Duration Portfolio and Fixed-Income Portfolio.

Mentor Investment Group, Inc. ("Mentor") provides administrative personnel and
services to each Portfolio, pursuant to an Administration Agreement. Mentor
receives no compensation for such services.

MENTOR INSTITUTIONAL TRUST
INDEPENDENT AUDITORS' REPORT

THE TRUSTEES AND SHAREHOLDERS
MENTOR INSTITUTIONAL TRUST

We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments, of the Cash Management Portfolio, Intermediate
Duration Portfolio and Fixed Income Portfolio, portfolios of Mentor
Institutional Trust (the Trust) as of October 31, 1995 and the related
statements of operations, statements of changes in net assets and financial
highlights for the period from December 5, 1994 (commencement of operations) to
October 31, 1995 for the Cash Management Portfolio, for the period from December
19, 1994 (commencement of operations) to October 31, 1995 for the Intermediate
Duration Portfolio and for the period from December 6, 1994 (commencement of
operations) to October 31, 1995 for the Fixed-Income Portfolio. These financial
statements and financial highlights are the responsibility of the Trust's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement. An audit also includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
October 31, 1995 by correspondence with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Cash Management Portfolio, Intermediate Duration Portfolio and Fixed Income
Portfolio, portfolios of Mentor Institutional Trust as of October 31, 1995, and
the results of their operations, the changes in their net assets and their
financial highlights for the periods specified in the first paragraph above, in
conformity with generally accepted accounting principles.

         Commonwealth Investment Counsel, Inc. ("CIC") serves as investment

                             INVESTMENT RESTRICTIONS

         As fundamental investment  restrictions,  which may not be changed with

                  if as a result: (i) as to 75% of the Fund's total assets, more
                  than 5% of the Fund's  total assets  (taken at current  value)

                  of cost or current  value) of its 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

         8.       Pledge,  hypothecate,  mortgage,  or  otherwise  encumber  its

                  that  the  Fund  may  purchase  or  sell   financial   futures
                  contracts,   options  on  futures   contracts,   and   futures
                  contracts,  forward  contracts,  and options  with  respect to

         In addition,  it is contrary to the current  policy of the Fund,  which
policy may be changed without shareholder approval, to:

         1.       Invest in (a) securities  which at the time of such investment
                  are not readily  marketable,  (b) securities  restricted as to
                  resale,  and (c) repurchase  agreements  maturing in more than
                  seven days,  if, as a result,  more than 10% of the Fund's net
                  assets  (taken at current  value)  would then be  invested  in
                  securities described in (a), (b), and (c).

         2.       Invest in securities of other registered investment companies,
                  except  by  purchases  in  the  open  market   involving  only
                  customary  brokerage  commissions and as a result of which not
                  more than 5% of its total  assets  (taken  at  current  value)
                  would be invested in such  securities,  or except as part of a
                  merger, consolidation, or other acquisition.


         All percentage  limitations  on  investments  will apply at the time of
investment and shall not be considered  violated  unless an excess or deficiency
occurs or exists  immediately  after and as a result of such investment.  Except
for the investment restrictions listed above as fundamental

or to the extent  designated  as such in a prospectus  with respect to the Fund,
the other investment policies described in this Statement or in a prospectus are
not fundamental  and may be changed by approval of the Trustees.  As a matter of
policy, the Trustees would not materially change the Fund's investment objective
without shareholder approval.

provides that a "vote of a majority of the outstanding voting securities" of the
Fund  means  the  affirmative  vote of the  lesser  of (1) more  than 50% of the
outstanding  shares of the Fund,  and (2) 67% or more of the shares present at a
meeting  if more  than 50% of the  outstanding  shares  are  represented  at the
meeting in person or by proxy.

         The Trustees do not receive  pension or  retirement  benefits  from the
Trust.

         The Agreement and  Declaration  of Trust of the Trust provides that the
Trust will indemnify its Trustees and officers against  liabilities and expenses
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 Agreement and Declaration of Trust that they have not acted in good faith
in the  reasonable  belief that their actions were in the best  interests of the
Trust or that such  indemnification  would relieve any officer or Trustee of any
liability to the Trust or its Shareholders by reason of willful misfeasance, bad
faith, gross negligence,  or reckless disregard of his or her duties. The Trust,
at its expense, provides liability insurance for the benefit of its Trustees and
officers.

                         PRINCIPAL HOLDERS OF SECURITIES
   
         As of February 15, 1996, the officers and Trustees of the Trust owned
as a group less than one  percent  of the  outstanding  shares of the Fund.  To
the knowledge  of  the  Fund,  no  person  owns  beneficially  or of record more
than  5% of the outstanding  shares of the Fund as of that  date except the
following.  All of the shares of the Fund are  registered  in the nominee  name
of the  Treasury  Board,  an agency of the Commonwealth of Virginia.

                     INVESTMENT ADVISORY AND OTHER SERVICES

         CIC acts as  investment  adviser to the Fund  pursuant to a  Management
Contract  with the  Trust.  Subject  to the  supervision  and  direction  of the
Trustees, CIC, as investment adviser, manages the Fund's portfolio in accordance
with the  stated  policies  of the Fund and of the Trust.  CIC makes  investment
decisions  for the Fund and places the  purchase  and sale orders for  portfolio
transactions.  CIC bears all expenses in connection  with the performance of its
services.  In addition,  CIC pays the salaries of all officers and employees who
are employed by it and the Trust.

         CIC provides the Trust on behalf of the Fund with  investment  officers
who are  authorized  to execute  purchases and sales of  securities.  Investment
decisions for the Fund and for the other investment  advisory clients of CIC and
its affiliates  are made with a view to achieving  their  respective  investment
objectives.  Investment decisions are the product of many factors in addition to
basic  suitability  for the  particular  client  involved.  Thus,  a  particular
security  may be bought or sold for  certain  clients  even though it could have
been bought or sold for other clients at the same time.  Likewise,  a particular
security may be bought for one or more  clients  when one or more other  clients
are selling the security.  In some  instances,  one client may sell a particular
security to another client.  It also sometimes  happens that two or more clients
simultaneously  purchase  or sell the same  security,  in which event each day's
transactions in such security are, insofar as possible, averaged as to price and
allocated between such clients in a manner which in

                                                      -7-


<PAGE>



CIC's  opinion is  equitable  to each and in  accordance  with the amount  being
purchased or sold by each. There may be circumstances when purchases or sales of
portfolio  securities  for one or more  clients  will have an adverse  effect on
other clients. In the case of short-term investments, the Treasury area of Wheat
First Butcher Singer handles  purchases and sales under  guidelines  approved by
investment  officers of the Trust. CIC employs  professional staffs of portfolio
managers who draw upon a variety of resources for research  information  for the
Fund.

         The proceeds received by the Fund for each issue or sale of its shares,
and all income,  earnings,  profits,  and proceeds thereof,  subject only to the
rights of creditors,  will be specifically allocated to the Fund, and constitute
the underlying  assets of the Fund.  The  underlying  assets of the Fund will be
segregated  on the  Trust's  books  of  account,  and will be  charged  with the
liabilities  in respect of the Fund and with a share of the general  liabilities
of the Trust.  Expenses  with  respect  to any two or more  series of the Trust,
including  the Fund,  may be allocated in  proportion to the net asset values of
the respective  series except where allocations of direct expenses can otherwise
be fairly made.

         Expenses  incurred in the operation of the Fund or otherwise  allocated
to the Fund,  including but not limited to taxes,  interest,  brokerage fees and
commissions, fees to Trustees who are not officers, directors,  stockholders, or
employees of Wheat First Butcher Singer and  subsidiaries,  SEC fees and related
expenses,  state  Blue Sky  qualification  fees,  charges of the  custodian  and
transfer and dividend disbursing agents, outside auditing, accounting, and legal
services,  investor  servicing  fees and  expenses,  charges for the printing of
prospectuses and statements of additional information for regulatory purposes or
for distribution to shareholders, certain shareholder report charges and charges
relating to corporate matters are borne by the Fund.

         The  Management  Contract  entered  into by the Trust in respect of the
Fund is subject to annual  approval  commencing  in 1997 by (i) the  Trustees or
(ii) vote of a majority (as defined in the 1940 Act) of the  outstanding  voting
securities of the Fund,  provided that in either event the  continuance  is also
approved by a majority of the  Trustees  who are not  "interested  persons"  (as
defined  in the 1940  Act) of the  Trust or CIC,  by vote  cast in  person  at a
meeting  called  for the  purpose  of voting on such  approval.  The  Management
Contract is terminable without penalty,  on not more than sixty days' notice and
not less than thirty days' notice, by the Trustees,  by vote of the holders of a
majority of the Fund's shares, or by CIC, as applicable.

                                    BROKERAGE

         Transactions on U.S. stock exchanges,  commodities markets, and futures
markets  and  other  agency  transactions  involve  the  payment  by the Fund of
negotiated brokerage commissions. Such commissions vary among different brokers.
A particular broker may charge different  commissions  according to such factors
as  the  difficulty  and  size  of  the  transaction.  Transactions  in  foreign
investments often involve the payment of fixed brokerage commissions,  which may
be  higher  than  those in the  United  States.  There is  generally  no  stated
commission in

                                                      -8-


<PAGE>



the case of securities  traded in the  over-the-counter  markets,  but the price
paid by the Fund usually includes an undisclosed  dealer  commission or mark-up.
In  underwritten  offerings,  the price paid by the Fund  includes a  disclosed,
fixed  commission  or discount  retained  by the  underwriter  or dealer.  It is
anticipated  that most  purchases and sales of securities by the Fund  investing
primarily  in certain  fixed-income  securities  will be with the issuer or with
underwriters   of  or  dealers  in  those   securities,   acting  as  principal.
Accordingly, the Fund would not ordinarily pay significant brokerage commissions
with respect to securities transactions.

         It has for many years been a common practice in the investment advisory
business for advisers of investment companies and other institutional  investors
to receive  brokerage  and  research  services  (as  defined  in the  Securities
Exchange Act of 1934, as amended (the "1934  Act")),  from  broker-dealers  that
execute  portfolio  transactions for the clients of such advisers and from third
parties with which such broker-dealers  have arrangements.  Consistent with this
practice,  CIC  receives  brokerage  and  research  services  and other  similar
services  from many  broker-dealers  with which it places  the Fund's  portfolio
transactions  and from  third  parties  with  which  these  broker-dealers  have
arrangements. These services include such matters as general economic and market
reviews,   industry   and   company   reviews,   evaluations   of   investments,
recommendations  as  to  the  purchase  and  sale  of  investments,  newspapers,
magazines,  pricing  services,  quotation  services,  news services and personal
computers  utilized by CIC's managers and analysts.  Where the services referred
to above are not used exclusively by CIC for research purposes,  CIC, based upon
its own  allocations  of expected  use,  bears that portion of the cost of these
services which directly relates to its non-research  use. Some of these services
are of  value to CIC and its  affiliates  in  advising  various  of its  clients
(including the Fund),  although not all of these services are necessarily useful
and of value in managing the Fund.

         CIC  places  all  orders  for  the   purchase  and  sale  of  portfolio
investments  for the Fund and buys and sells  investments for the Fund through a
substantial  number of brokers and  dealers.  CIC seeks the best  overall  terms
available for the Fund,  except to the extent CIC may be permitted to pay higher
brokerage  commissions as described  below. In doing so, CIC, having in mind the
Fund's best interests,  considers all factors it deems relevant,  including,  by
way of  illustration,  price,  the size of the  transaction,  the  nature of the
market for the security or other investment,  the amount of the commission,  the
timing of the  transaction  taking into account  market  prices and trends,  the
reputation, experience and financial stability of the broker-dealer involved and
the quality of service rendered by the broker-dealer in other transactions.

         As  permitted by Section  28(e) of the 1934 Act, and by the  Management
Contract,  CIC  may  cause  the  Fund  to  pay a  broker-dealer  which  provides
"brokerage and research  services" (as defined in the 1934 Act) to CIC an amount
of disclosed commission for effecting securities transactions on stock exchanges
and  other  transactions  for the  Fund on an  agency  basis  in  excess  of the
commission  which another  broker-dealer  would have charged for effecting  that
transaction.  CIC's  authority  to  cause  the  Fund  to pay  any  such  greater
commissions is also subject to such policies as the Trustees may adopt from time
to time. CIC does not currently  intend to cause the Fund to make such payments.
It is the position of the staff of the Securities

                                                      -9-


<PAGE>



and Exchange Commission that Section 28(e) does not apply to the payment of such
greater commissions in "principal" transactions.  Accordingly,  CIC will use its
best efforts to obtain the best  overall  terms  available  with respect to such
transactions, as described above.

         Consistent with the Rules of Fair Practice of the National  Association
of Securities  Dealers,  Inc. and subject to such other policies as the Trustees
may  determine,  CIC may consider sales of shares of the Fund (and, if permitted
by law, of other Mentor funds) as a factor in the selection of broker-dealers to
execute portfolio transactions for the Fund.

                        DETERMINATION OF NET ASSET VALUE

         The Trust  determines  net asset value per share of the Fund twice each
day the New York Stock Exchange (the "Exchange") is open, once at 12:00 noon and
again at the close of regular trading on the New York Stock Exchange. Currently,
the Exchange is closed  Saturdays,  Sundays,  and the  following  holidays:  New
Year's Day,  Presidents'  Day,  Good Friday,  Memorial  Day, the Fourth of July,
Labor Day, Thanksgiving, and Christmas.

         The  valuation  of the Fund's  portfolio  securities  is based upon its
amortized cost, which does not take into account unrealized  securities gains or
losses.  This method  involves  initially  valuing an instrument at its cost and
thereafter  assuming a constant  amortization  to  maturity  of any  discount or
premium,  regardless of the impact of  fluctuating  interest rates on the market
value of the instrument.  By using  amortized cost valuation,  the Fund seeks to
maintain a constant net asset value of $1.00 per share,  despite minor shifts in
the  market  value of its  portfolio  securities.  While  this  method  provides
certainty  in  valuation,  it may  result in  periods  during  which  value,  as
determined  by amortized  cost, is higher or lower than the price the Fund would
receive if it sold the instrument.  During periods of declining  interest rates,
the  quoted  yield on  shares  of the Fund  may  tend to be  higher  than a like
computation  made by a fund with  identical  investments  utilizing  a method of
valuation  based on market  prices and estimates of market prices for all of its
portfolio  instruments.  Thus, if the use of amortized cost by the Fund resulted
in a lower aggregate portfolio value on a particular day, a prospective investor
in the Fund  would be able to obtain a  somewhat  higher  yield if he  purchased
shares of the Fund on that day,  than would  result  from  investment  in a fund
utilizing solely market values, and existing investors in the Fund would receive
less  investment  income.  The  converse  would  apply  on a day when the use of
amortized  cost by the Fund  resulted  in a higher  aggregate  portfolio  value.
However,  as a result of certain  procedures  adopted  by the  Trust,  the Trust
believes any difference will normally be minimal.

         The valuation of the Fund's portfolio  instruments at amortized cost is
permitted in accordance  with  Securities and Exchange  Commission Rule 2a-7 and
certain  procedures  adopted by the Trustees.  Under these procedures,  the Fund
must maintain a dollar-weighted  average portfolio  maturity of 90 days or less,
purchase only instruments  having remaining  maturities of 397 days or less, and
invest in  securities  determined  by the  Trustees to be of high  quality  with
minimal credit risks. The Trustees have also established  procedures designed to
stabilize, to the

                                                      -10-


<PAGE>



extent  reasonably  possible,  the Fund's  price per share as  computed  for the
purpose of  distribution,  redemption and repurchase at $1.00.  These procedures
include  review  of the  Fund's  portfolio  holdings  by the  Trustees,  at such
intervals  as they may deem  appropriate,  to  determine  whether the Fund's net
asset value  calculated by using readily  available market  quotations  deviates
from $1.00 per share,  and, if so, whether such deviation may result in material
dilution  or is  otherwise  unfair to  existing  shareholders.  In the event the
Trustees  determine that such a deviation may result in material  dilution or is
otherwise unfair to existing shareholders, they will take such corrective action
as they regard as necessary  and  appropriate,  including  the sale of portfolio
instruments  prior to maturity to realize  capital gains or losses or to shorten
the average portfolio maturity;  withholding dividends;  redemption of shares in
kind; or  establishing  a net asset value per share by using  readily  available
market quotations.

         Since the net income of the Fund is declared as a dividend each time it
is  determined,  the net asset value per share of the Fund  remains at $1.00 per
share  immediately  after  such  determination  and  dividend  declaration.  Any
increase in the value of a shareholder's investment in the Fund representing the
reinvestment  of dividend  income is  reflected  by an increase in the number of
shares of the Fund in the  shareholder's  account  on the last day of each month
(or,  if that day is not a  business  day,  on the  next  business  day).  It is
expected that the Fund's net income will be positive each time it is determined.
However,  if because of realized  losses on sales of  portfolio  investments,  a
sudden rise in  interest  rates,  or for any other  reason the net income of the
Fund  determined  at any time is a negative  amount,  the Fund will  offset such
amount  allocable  to each then  shareholder's  account from  dividends  accrued
during the month with  respect to such  account.  If at the time of payment of a
dividend by the Fund (either at the regular monthly  dividend  payment date, or,
in the case of a shareholder who is withdrawing all or substantially  all of the
shares in an account, at the time of withdrawal), such negative amount exceeds a
shareholder's accrued dividends,  the Fund will reduce the number of outstanding
shares by treating the  shareholder as having  contributed to the capital of the
Fund that number of full and fractional shares which represent the amount of the
excess.  Each shareholder is deemed to have agreed to such contribution in these
circumstances by its investment in the Fund.

         Should  the  Fund  incur  or  anticipate   any  unusual  or  unexpected
significant  expense or loss which would  affect  disproportionately  the Fund's
income for a particular period, the Trustees would at that time consider whether
to adhere to the dividend policy described above or to revise it in light of the
then prevailing  circumstances in order to ameliorate to the extent possible the
disproportionate  effect of such expense or loss on then existing  shareholders.
Such expenses or losses may nevertheless result in a shareholder's  receiving no
dividends  for the period  during which the shares are held and  receiving  upon
redemption a price per share lower than that which was paid.

                                   TAX STATUS

         The Fund  intends  to  qualify  each  year  and  elect to be taxed as a
regulated  investment  company under  Subchapter M of the United States Internal
Revenue Code of 1986, as amended (the "Code").

         As a regulated  investment company qualifying to have its tax liability
determined  under  Subchapter M, the Fund will not be subject to federal  income
tax on any of its net investment  income or net realized  capital gains that are
distributed to shareholders.  As a series of  Massachusetts  business trust, the
Fund will not under  present  law be subject  to any  excise or income  taxes in
Massachusetts.

         In order to qualify as a "regulated investment company," the Fund must,
among other things,  (a) derive at least 90% of its gross income from dividends,
interest,  payments  with respect to  securities  loans,  gains from the sale or
other dispositions of stock, securities, or foreign currencies, and other income
(including but not limited to gains from options, futures, or forward contracts)
derived with respect to its business of investing in such stock, securities,  or
currencies;  (b) derive less than 30% of its gross income from the sale or other
disposition  of certain  assets  (including  stock and  securities  and  certain
options, futures contracts, forward contracts, and foreign currencies) held less
than three  months;  (c)  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 value 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 assets is invested in the
securities  (other  than  U.S.  Government  securities  or  securities  of other
regulated  investment  companies) of any issuer or two or more issuers which the
Fund controls and which are engaged in the same,  similar,  or related trades or
businesses.  In order to receive the favorable tax treatment  accorded regulated
investment companies and their shareholders,  moreover, the Fund must in general
distribute at least 90% of its interest, dividends, net short-term capital gain,
and certain other income each year.

         An excise tax at the rate of 4% will be imposed on the excess,  if any,
of the  Fund's  "required  distribution"  over its actual  distributions  in any
calendar  year.  Generally,  the  "required  distribution"  is 98% of the Fund's
ordinary  income for the  calendar  year plus 98% of its capital gain net income
recognized  during the one-year  period ending on October 31 (or December 31, if
the Fund so  elects)  plus  undistributed  amounts  from prior  years.  The Fund
intends to make distributions  sufficient to avoid imposition of the excise tax.
Distributions  declared by the Fund  during  October,  November,  or December to
shareholders  of record on a date in any such month and paid by the Fund  during
the  following  January  will be treated for federal tax purposes as paid by the
Fund and received by shareholders on December 31 of the year in which declared.


                                                      -12-


<PAGE>



         The Fund is  required  to  withhold  31% of all  income  dividends  and
capital gain distributions,  and 31% of the gross proceeds of all redemptions of
Fund  shares,  in the case of any  shareholder  who does not  provide  a correct
taxpayer  identification  number,  about  whom  the  Fund is  notified  that the
shareholder  has under  reported  income in the past, or who fails to certify to
the Fund that the  shareholder  is not subject to such  withholding.  Tax-exempt
shareholders are not subject to these back-up  withholding rules so long as they
furnish the Fund with a proper certification.

         As stated above, it is a policy of the Fund to meet the requirements of
the code to qualify as a regulated  investment company that is taxed pursuant to
Subchapter M of the Code. One of these requirements is that less than 30% of the
Fund's gross income must be derived from gains from sale or other disposition of
securities  held for less  than  three  months.  Accordingly,  the Fund  will be
restricted in selling  securities  held or  considered  under Code rules to have
been held less than three months.

         The foregoing is a general and  abbreviated  summary of the  applicable
provisions  of the Code and related  regulations  currently  in effect.  For the
complete provisions, reference should be made to the pertinent Code sections and
regulations.  The Code and  regulations  are subject to change by legislative or
administrative actions. Dividends and distributions also may be subject to state
and  federal  taxes.  Shareholders  are  urged to  consult  their  tax  advisers
regarding specific questions as to federal,  state or local taxes. The foregoing
discussion  relates solely to U.S.  federal income tax law.  Non-U.S.  investors
should consult their tax advisers  concerning the tax  consequences of ownership
of shares of the Fund,  including  the  possibility  that  distributions  may be
subject to a 30% United States withholding tax (or a reduced rate of withholding
provided by treaty).

                             INDEPENDENT ACCOUNTANTS

                             PERFORMANCE INFORMATION

   
         The yield of the Fund is computed by  determining  the  percentage  net
change, excluding capital changes, in the value of an investment in one share of
the Fund  over the base  period,  and  multiplying  the net  change by 365/7 (or
approximately 52 weeks).  The Fund's effective yield represents a compounding of
the yield by adding 1 to the number  representing the percentage change in value
of the investment  during the base period,  raising that sum to a power equal to
365/7,  and subtracting 1 from the result.  Based on the seven-day  period ended
December 31, 1995, the Fund's yield was 5.66% and its effective yield was 5.82%.
    
         All data for the Fund is based on past performance and does not predict
future results.


                              SHAREHOLDER LIABILITY

         Under   Massachusetts   law,    shareholders   could,   under   certain
circumstances,  be held  personally  liable  for the  obligations  of the Trust.
However, the Agreement and 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 Agreement and  Declaration  of Trust provides
for  indemnification  out of the Fund's property for all loss and expense of any
shareholder  held  personally  liable for the  obligations of the Fund. Thus the
risk of a  shareholder's  incurring  financial  loss on account  of  shareholder
liability is limited to  circumstances in which the Fund would be unable to meet
its obligations.

                                     RATINGS

A-1 AND PRIME-1 COMMERCIAL PAPER RATINGS

The rating A-1 (including A-1+) is the highest  commercial paper rating assigned
by S&P. Commercial paper rated A-1 by S&P has the following characteristics:

  (BULLET)         liquidity ratios are adequate to meet cash requirements;

  (BULLET)         long-term senior debt is rated "A" or better;

  (BULLET)         the issuer has access to at least two additional channels of
                   borrowing;

  (BULLET)         basic earnings and cash flow have an upward trend with
                   allowance made for unusual circumstances;

  (BULLET)         typically, the issuer's industry is well established and the
                   issuer has a strong position within the industry; and

  (BULLET)         the reliability and quality of management are unquestioned.

Relative  strength  or  weakness  of the above  factors  determines  whether the
issuer's  commercial  paper is rated A-1, A-2 or A-3.  Issues rated A-1 that are
determined by S&P to have  overwhelming  safety  characteristics  are designated
A-1+.

The rating Prime-1 is the highest  commercial  paper rating assigned by Moody's.
Among the factors considered by Moody's in assigning ratings are the following:

  (BULLET)         evaluation of the management of the issuer;

  (BULLET)         economic evaluation of the issuer's industry or industries
                   and an appraisal of speculative-type risks which may be
                   inherent in certain areas;

  (BULLET)         evaluation of the issuer's products in relation to
                   competition and customer acceptance;

  (BULLET)         liquidity;

                                                    -15-

  (BULLET)         amount and quality of long-term debt;

  (BULLET)         trend of earnings over a period of ten years;

  (BULLET)         financial strength of parent company and the relationships
                   which exist with the issuer; and

  (BULLET)         recognition  by the  management  of obligations  which may be
                   present or may arise as a result of public interest questions
                   and preparations to meet such obligations.

SNAP FUND
NOTES TO FINANCIAL STATEMENTS
December 31, 1995 (Unaudited)
- -------------------------------------------------------------------------------

NOTE 1: ORGANIZATION
SNAP Fund (the "Fund") is an open-end  management  investment company registered
under the  Investment  Company Act of 1940, as amended.  The Fund is a series of
shares of beneficial  interest of Mentor  Institutional  Trust, a Massachussetts
business trust.

Prior  to July 24,  1995,  the Fund was  known as the  Mentor  Limited  Duration
Portfolio and had no shares outstanding.

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES
The  following  is a summary of  significant  accounting  policies  consistently
followed by the Fund:

A. VALUATION OF SECURITIES
Investments are stated at amortized cost,  which  approximates  market value. In
the event that a deviation  of 1/2 of 1% or more exists  between a Fund's  $1.00
per share net asset value, calculated at amortized cost, and the net asset value
calculated  by  reference  to  market-based  values,  or if there  is any  other
deviation  that the  Board of  Trustees  believes  would  result  in a  material
dilution to  shareholders  or  purchasers,  the Board of Trustees  will promptly
consider what action should be initiated.

B. REPURCHASE AGREEMENTS
It is the policy of the Fund to require the custodian  bank to take  possession,
to have legally  segregated in the Federal Reserve Book entry system, or to have
segregated  within  the  custodian  bank's  possession  all  securities  held as
collateral  in  support  of  repurchase  agreement  investments.   Additionally,
procedures have been established by the Trust to monitor,  on a daily basis, the
market value of each repurchase  agreement's underlying securities to ensure the
existence of a proper level of collateral.

The Fund will enter into repurchase  agreements with banks and other  recognized
financial  institutions,  such as broker/dealers  which are deemed by the Fund's
investment adviser to be credit-worthy,  only pursuant to guidelines established
by the Board of  Trustees.  Risks  may arise  from the  potential  inability  of
counterparties to honor the terms of the repurchase agreement.  Accordingly, the
Fund could  receive  less than the  repurchase  price on the sale of  collateral
securities.

C. INVESTMENT TRANSACTIONS
Investment  transactions  are  accounted  for on the trade  date and the cost of
investments sold is determined by use of the specific identification method.

D. INTEREST INCOME AND EXPENSES
Interest  income is recorded on the accrual basis and includes  amortization  of
premiums and discounts on investments.  Expenses  arising in connection with the
operation of the Fund are recorded on the accrual basis and paid from the income
of the Fund.  Organizational expenses are related to registration of the Fund as
Regulated   Investment   Company.   Such  expenses  are  being  amortized  on  a
straight-line method over 60 months.

E. DISTRIBUTIONS TO SHAREHOLDERS
Dividends, equal to the net investment income plus or minus any net realized
gains or losses, are declared daily and paid monthly.

SNAP FUND
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
- --------------------------------------------------------------------------------

F. FEDERAL INCOME TAXES
No provision  for federal  income taxes has been made as it is the Fund's policy
to comply with the provisions applicable to regulated investment companies under
the  Internal  Revenue Code and to  distribute  to its  shareholders  within the
allowable time limit substantially all taxable income and realized capital gain.

NOTE 3: INVESTMENT MANAGEMENT FEES
The Fund has entered into an Investment  Management  Agreement with Commonwealth
Investment  Counsel,  Inc.   ("Commonwealth")  to  provide  investment  advisory
services to the Fund. The Fund pays advisory fees to Commonwealth monthly at the
following  annual rates  expressed as percentage of the average daily net assets
of the Fund:

    Average Daily Net Assets                 Rate
    -------------------------            --------------
    First        $500 million                0.09%

    Next         $250 million                0.08%

    Next         $250 million                0.07%
    Next         $250 million                0.06%
    Over         $1.25 million               0.05%


NOTE 4: INVESTMENTS
In accordance  with  Statement No. 3 of the  Governmental  Accounting  Standards
Board,  credit  risk is the  risk  that an  investor  may not be able to  obtain
possession of its investment instrument or collateral at maturity. Risk category
1  includes  investments  that  are  insured  or  registered  or for  which  the
securities  are held by the investor or its agent in the investor's  name.  Risk
category  2  includes  uninsured  or  unregistered  investments  for  which  the
securities are held by the broker's or dealer's trust department or agent in the
investor's name. Risk category 3 includes uninsured or unregistered  investments
for which the  securities  are held by the  broker  or  dealer,  or by its trust
department or agent but not in the  investor's  name.  All  investments  held at
December 31, 1995 are in risk category 1.

NOTE 5: CAPITAL SHARE INFORMATION
Net assets consist entirely of paid-in-capital  applicable to 897,691,373 no par
value shares of beneficial interest  outstanding.  An unlimited number of shares
have been authorized.
