                        THE ROXBURY LARGE CAP GROWTH FUND

PORTFOLIO DESCRIPTION
         PLAIN TALK
         -----------------------------------------------------------------------
         WHAT IS A MUTUAL FUND?
         A mutual fund pools shareholders' money and, using a professional
         investment manager, invests in securities like stocks and bonds.
         -----------------------------------------------------------------------

SUMMARY
         PLAIN TALK
         -----------------------------------------------------------------------
         WHAT DOES "CAP" MEAN?
         Cap or the market capitalization of a company means the value of all of
         the shares of the company's common stock in the stock market.
         -----------------------------------------------------------------------

Investment Objective   (BULLET) The ROXBURY LARGE CAP GROWTH FUND seeks superior
                                long-term growth of capital.
- --------------------------------------------------------------------------------
Investment Focus       (BULLET) Equity securities (generally common stocks)
- --------------------------------------------------------------------------------
Share Price Volatility (BULLET) Moderate to high
- --------------------------------------------------------------------------------
Principal Investment            The Fund invests in a diversified  portfolio of
Strategy                        equity securities (generally commonstocks)  of
                                U.S.  corporations  with a market cap of $5
                                billion or more that have above average earnings
                                potential, compared to the securities market as
                                a whole.
                       (BULLET) The Fund  operates  as a  "feeder  fund"  which
                                means  that the Fund  does not buy individual
                                securities directly. Instead, it invests in a
                                corresponding mutual fund or "master fund,"
                                which in turn purchases the actual stock
                                holdings. The Fund's master fund is the Large
                                Cap Growth Series (the "Series") of WT
                                Investment Trust I ("the Master").
                       (BULLET) In a master/feeder arrangement, a feeder  fund,
                                like the Fund, takes your investment dollars and
                                transfers them to an even larger pool, like the
                                Series, for greater efficiency. The Fund and the
                                Series have the same investment objective,
                                policies and limitations. When this prospectus
                                refers to investments of the Fund it is actually
                                referring to the investments of the
                                Series.
                       (BULLET) The adviser purchases stocks it believes exhibit
                                consistent, above-average earnings growth,
                                superior quality and attractive risk/reward
                                characteristics. The adviser analyzes the stocks
                                of over 2000 companies using a bottom-up
                                approach to search for high quality companies
                                which are growing at about double the market's
                                average rate. The adviser generally sells stocks
                                when the risk/rewards of a stock turn negative,
                                when company fundamentals deteriorate, or when a
                                stock under performs the market or its peer
                                group.
- --------------------------------------------------------------------------------
Principal Risks        The Fund is subject  to the  following  risks  summarized
                       below which are further  described under "Additional Risk
                       Information."
                       (BULLET) There is no guarantee that the stock market or
                                the stocks that the Fund buys will always
                                increase in value. Therefore, it is possible to
                                lose money by investing in the Fund.
                       (BULLET) The Fund's share price will fluctuate in
                                response to changes in the market value of the
                                Fund's investments. Market value will change as
                                a result of business developments affecting an
                                issuer as well as general market and economic
                                conditions.
                       (BULLET) Growth-oriented investments may be more volatile
                                than the rest of the U.S. stock market as a
                                whole.
                       (BULLET) The performance of the Fund will depend on how
                                successfully the adviser pursues its investment
                                strategy.
- --------------------------------------------------------------------------------
Investor Profile       (BULLET) Investors who want the value of their investment
                                to grow and who are willing to accept more
                                volatility for the possibility of higher growth
                                returns.

FEES AND EXPENSES
         PLAIN TALK
         -----------------------------------------------------------------------
         WHAT ARE FUND EXPENSES?
         Every mutual fund has operating expenses to pay for professional
         advisory, distribution, administration and custody services. The Fund's
         expenses in the table below are shown as a percentage of its average
         annual net assets. Sales charges are deducted once when you make or
         redeem your investment. Expenses are deducted from Fund assets.
         -----------------------------------------------------------------------

The table below describes the fees and expenses that you may pay if you buy and
hold shares of the Fund. The Fund offers different share classes to allow you to
maximize your potential return depending on your and your financial consultant's
current expectations for your investment in the Fund.

         PLAIN TALK
         -----------------------------------------------------------------------
         WHAT ARE SALES CHARGES?
         The sales charge or load that you pay is a separate fee based on how
         much you invest. This fee compensates your financial consultant for
         providing you with investment assistance and on-going service as well
         as handling all the paperwork associated with your investment and any
         subsequent adjustments you make. For your convenience, the Fund is
         offered in several classes, giving you several ways to pay this fee.

(a)  Class B shares convert to Class A shares automatically at the beginning of
     the seventh year after purchase. Investors seeking to purchase Class B
     shares in amounts that exceed $250,000 should discuss with their financial
     consultant whether the purchase of another class would be more appropriate.
(b)  Reduced for purchases of $50,000 and more.
(c)  Class A shares are not subject to a contingent deferred sales charge (a
     "CDSC"); except certain purchases that are not subject to an initial sales
     charge may instead be subject to a CDSC of 1.00% of amounts redeemed within
     the first year of purchase. Such a CDSC may be waived in connection with
     redemptions to participants in certain fee-based programs.
(d)  5.00% during the first year, 4.00% during the second year, 3.00% during the
     third year; 2.00% during the fourth year, 2.00% during the fifth year,
     1.00% during the sixth year. Class B shares automatically convert into
     Class A shares at the beginning of the seventh year after purchase and
     thereafter will not be subject to a CDSC.
(e)  Class C shares are subject to a 1.00% CDSC only if redeemed within the
     first 18 months after purchase.
(f)  If you effect a redemption via wire transfer, you may be required to pay
     fees, including a $10 wire fee and other fees, that will be directly
     deducted from your redemption proceeds. If you request redemption checks to
     be sent by overnight mail, you may be required to pay a $10 fee that will
     be directly deducted from your redemption proceeds.

- -------------------------
1 The table above and the example below each reflect the aggregate annual
operating expenses of the Fund and the Series.
2 "Other expenses" are based on estimated amounts for the current fiscal year.
3 The adviser has agreed to reduce its fees and/or reimburse expenses to limit
the total annual operating expenses to 1.30% for Class A Shares, 2.05% for each
of Class B shares and Class C shares. This arrangement will remain in place
until the Board of Trustees approves its termination.

EXAMPLE
This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds. The table below shows what you
would pay if you invested $10,000 over the various time frames indicated. The
example assumes that:

 (BULLET) you reinvested all dividends and other distributions
 (BULLET) the average annual return was 5%
 (BULLET) the Fund's maximum total operating expenses are charged and remain the
          same over the time periods
 (BULLET) you redeemed all of your investment at the end of the time period.

Although your actual cost may be higher or lower, based on these assumptions,
your costs would be:

                                                        1 YEAR       3 YEARS
                                                        ------       -------

Class A 1                                                $675         $939

Class B                                                  $208         $643

Class B (assuming complete redemption at the end of
the 1 year or 3 year period) 2                           $768        $1,043

Class C                                                  $208         $643

Class C (assuming complete redemption at end of          $308         $643
period) 2

1  Assumes deduction at time of purchase of maximum sales charge.
2  Assumes deduction at redemption of maximum deferred sales charge.

THE ABOVE EXAMPLE IS FOR COMPARISON PURPOSES ONLY AND IS NOT A REPRESENTATION OF
THE FUND'S ACTUAL EXPENSES AND RETURNS, EITHER PAST OR FUTURE.

ADVISER PRIOR PERFORMANCE
The table below shows relevant performance data for the adviser and its
predecessors' investment advisory accounts (the "Accounts") during the ten year
period ended September 30, 1999, using the same investment approach specified
for the Fund under "Investment Objective" and "Primary Investment Strategies."

The results for the period October 1, 1989 through July 31, 1998 are the results
of Roxbury Capital Management Inc., the predecessor to Roxbury Capital
Management, LLC.

The Accounts constitute the portfolios managed by the adviser (and its
predecessor) that have an identical or substantially similar investment
objective or investment approach as the Series and that met certain basic
criteria as to minimum account value, discretionary status, tax-exempt status
and period of management of more than one month. The Accounts were managed for
tax-exempt clients and, therefore, may have been managed differently than for
taxable clients. The Series will be managed primarily for taxable investors. The
Accounts were not subject to the same types of expenses to which the Fund is
subject, nor to the diversification requirements, specific tax restrictions and
investment limitations imposed on the Fund by the Investment Company Act of
1940, or the Internal Revenue Code of 1986. The performance of the Accounts may
have been adversely affected had they been subject to the same expenses,
restrictions and limitations. The adviser believes that any adverse effect would
not have been significant. The results presented are not intended to predict or
suggest the return to be experienced by the Fund or the return you might achieve
by investing in the Fund. You should not rely on the following performance data
as an indication of future performance of the adviser or of the Fund.

1.   The results for the Accounts reflect both income and capital appreciation
     or depreciation (total return). Dividends are accounted for on a cash
     basis; other items of income are accounted for on an accrual basis. Returns
     are time-weighted and represent the dollar-weighted average of the
     Accounts. Return figures are net of applicable fees and expenses (other
     than separate custody fees). As of April 1, 1995, the Accounts were valued
     daily.

2.   The S&P 500 Index consists of 500 stocks chosen by Standard & Poor's for
     market size, liquidity and industry group representation. It is a
     market-value weighted unmanaged index (stock price times number of shares
     outstanding), with each stock's weight in the S&P 500 Index proportionate
     to its market value.

         PLAIN TALK
         -----------------------------------------------------------------------
         WHAT IS AN INDEX?
         An index is a broad measure of the market performance of a specific
         group of securities in a particular market or securities in a market
         sector. You cannot invest directly in an index. An index does not have
         an adviser and does not pay any commissions or expenses. If an index
         had expenses, its performance would be lower.
         -----------------------------------------------------------------------

     SPECIAL NOTE CONCERNING ADVISER INVESTMENT RETURNS: You should note that
     the Fund will compute and disclose its average annual compounded rate of
     return using the standard formula set forth in SEC rules, which differs in
     certain respects from the method used to compute the returns for the
     Accounts noted above. The SEC total return calculation method calls for
     computation and disclosure of an average annual compounded rate of return
     for one, five and ten year periods or shorter periods from inception. The
     SEC formula provides a rate of return that equates a hypothetical initial
     investment of $10,000 to an ending redeemable value. The returns shown for
     the Accounts are reduced to reflect the deduction of advisory fees in
     accordance with the SEC calculation formula, which requires that returns
     shown for a fund be net of advisory fees as well as all other applicable
     fund operating expenses. Performance was calculated on a trade date basis.

INVESTMENT OBJECTIVE
The Fund and the Series seek superior long-term growth of capital.

For purposes of this investment objective, "superior" long-term growth of
capital means long-term growth of capital from an investment in the securities
comprising the S&P 500 Index that exceeds the return of the S&P 500 Index. This
investment objective may not be changed without shareholder approval. There is
no guarantee that the Fund will achieve its investment objective.

PRIMARY INVESTMENT STRATEGIES
         PLAIN TALK
         -----------------------------------------------------------------------
         WHAT ARE GROWTH FUNDS?
         Growth funds invest in the common stock of growth-oriented companies
         seeking maximum growth of earnings and share price with little regard
         for dividend earnings. Generally, companies with high relative rates of
         growth tend to reinvest more of their profits into the company and pay
         out less to shareholders in the form of dividends. As a result,
         investors in growth funds tend to receive most of their return in the
         form of capital appreciation.
         -----------------------------------------------------------------------

The Fund invests its assets in the Series, which, under normal market
conditions, invests at least 65%, and typically more, of its total assets in the
following equity (or equity-related) securities:
(BULLET)  common stocks of U.S. corporations that are judged by the adviser to
          have strong growth characteristics and, with respect to at least 65%
          of the Series' total assets, have a market capitalization of $5
          billion or higher at the time of purchase;
(BULLET)  securities convertible into the common stock of U.S. corporations
          described above;
(BULLET)  options on common stock or options on stock indexes.

The adviser looks for high quality, sustainable growth stocks while paying
careful attention to valuation. Research is bottom-up, emphasizing business
fundamentals, including financial statement analysis and industry and competitor
evaluations. The adviser selects stocks it believes exhibit consistent,
above-average earnings growth, superior quality and attractive risk/reward
characteristics. These dominant companies are expected to generate consistent
earnings growth in a variety of economic environments.

The adviser also seeks to provide a greater margin of safety and stability in
its investments. Superior earnings growth is expected to translate ultimately
into superior compounding of returns. Additionally, several valuation tools are
used to avoid over-paying for growth or chasing "hot" stocks. Over time, the
adviser believes these favorable characteristics will produce superior returns
with less risk than many other growth styles.

The adviser's research team analyzes a broad universe of over 2,000 companies.
Industry specialists search for high-quality companies that are growing their
earnings at roughly double the market's average. Approximately 150 stocks pass
these initial screens and are subject to thorough research. Dominant market
share, strong financials, the power to price, significant free cash flow and
shareholder-oriented management are critical attributes or factors.

Final purchase candidates are selected by the adviser's investment committee
based on attractive risk/reward characteristics and diversification guidelines.
Certain industries may be over or under-weighted by the adviser based upon
favorable growth rates or valuation parameters.

The adviser attempts to maintain portfolio continuity by purchasing growth
companies that are less sensitive to short-term economic trends than cyclical,
low quality companies. The adviser generally sells stocks when the risk/reward
characteristics of a stock turn negative, company

                                      -8-
<PAGE>


fundamentals deteriorate, or the stock underperforms the market or its peer
group. The latter device is employed to minimize mistakes and protect capital.

The Fund's investments will emphasize large cap growth stocks, but also may
include medium cap stocks and special situations.


LARGE CAP  GROWTH  STOCKS  (over $5  billion  in total  market  cap) - Up to
100%,  but not less  than 65%,  of the Series'total assets:

(BULLET) Mature, predictable businesses
(BULLET) Capital appreciation and income
(BULLET) Highest liquidity


MEDIUM CAP GROWTH STOCKS (between $1 and $5 billion in total market cap) - Up to
20% of the Series' total assets:

(BULLET) Superior long-term potential
(BULLET) Strong niche or franchise
(BULLET) Seasoned management


SPECIAL SITUATIONS GROWTH OPPORTUNITIES - Up to 20% of the Series' total assets:

(BULLET) Stable return, independent of the market
(BULLET) Unusually favorable risk/reward characteristics
(BULLET) Typically involve corporate restructuring

In order to respond to adverse market, economic, political or other conditions,
the Fund may assume a temporary defensive position and invest without limit in
commercial paper and other money market instruments that are rated investment
grade. The result of this action may be that the Fund will be unable to achieve
its investment objective. The Fund also may use other strategies and engage in
other investment practices, which are described in detail in our Statement of
Additional Information.

ADDITIONAL RISK INFORMATION
The following is a list of certain risks that may apply to your investment in
the Fund. Further information about investment risk is available in our
Statement of Additional Information:

(BULLET)  MARKET RISK: The risk that the market value of a security may move up
          and down, sometimes rapidly and unpredictably. The prices of equity
          securities change in response to many factors including the historical
          and prospective earnings of the issuer, the value of its assets,
          general economic conditions, interest rates, investor perceptions and
          market liquidity.
(BULLET)  GROWTH-ORIENTED INVESTING RISK: The risk that an investment in a
          growth-oriented portfolio may be more volatile than the rest of the
          U.S. market as a whole.
(BULLET)  DERIVATIVES RISK: Some of the Fund's investments may be referred to as
          "derivatives" because their value depends on, or derives from, the
          value of an underlying asset, reference

                                      -9-
<PAGE>


          rate or index. These investments include options, futures contracts
          and similar investments that may be used in hedging and related income
          strategies. The market value of derivative instruments and securities
          is sometimes more volatile than that of other investments, and each
          type of derivative may pose its own special risks. As a fundamental
          policy, no more than 15% of the Master's total assets may at any time
          be committed or exposed to derivative strategies.
(BULLET)  MASTER/FEEDER RISK: The master /feeder structure is relatively new and
          complex. While this structure is designed to reduce costs, it may not
          do so, and there may be operational or other complications. For
          example, large-scale redemptions by other feeders of their shares of
          the master fund could have adverse effects on a fund such as requiring
          the liquidation of a substantial portion of the master fund's holdings
          at a time when it could be disadvantageous to do so. Also, other
          feeders of a master fund may have a greater ownership interest in the
          master fund and, therefore, could have effective voting control over
          the operation of the master fund.
(BULLET)  OPPORTUNITY RISK: The risk of missing out on an investment opportunity
          because the assets necessary to take advantage of it are tied up in
          less advantageous investments.

SHAREHOLDER INFORMATION
HOW SHARE PRICE IS CALCULATED
The Fund values its assets based on current market values when such values are
readily available. These prices normally are supplied by a pricing service. Any
assets held by the Fund that are denominated in foreign currencies are valued
daily in U.S. dollars at the foreign currency exchange rates that are prevailing
at the time that PFPC determines the Fund's daily net asset value. To determine
the value of those securities, PFPC may use a pricing service that takes into
account not only developments related to specific securities, but also
transactions in comparable securities. Securities that do not have a readily
available current market value are valued in good faith under the direction of
the Board of Trustees. The Fund is subject to the risk that it has valued
certain of its stocks at a higher price than it can sell them.

         PLAIN TALK
         -----------------------------------------------------------------------
         WHAT IS THE NET ASSET VALUE or "NAV"?
                           NAV = ASSETS - LIABILITIES
                           --------------------------
                              Outstanding Shares

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

PFPC determines the NAV per share of the Fund as of the close of regular trading
on the New York Stock Exchange (currently 4:00 p.m., Eastern time), on each
Business Day (a day that the Exchange, the Transfer Agent and the Philadelphia
branch of the Federal Reserve Bank are open for business). The NAV is calculated
by adding the value of all securities and other assets in the Fund, deducting
its liabilities and dividing the balance by the number of outstanding shares in
the Fund.

Shares will not be priced on those days the Fund is closed. As of the date of
this prospectus, those days are:

     New Year's Day                Memorial Day          Veterans Day
     Martin Luther King, Jr. Day   Independence Day      Thanksgiving Day
     Presidents' Day               Labor Day             Christmas Day
     Good Friday                   Columbus Day


SELECTING THE CORRECT CLASS OF SHARES
This prospectus offers Class A, Class B and Class C shares of the Fund. Each
class has its own cost structure, allowing you to choose the one that best meets
your requirements and current expectations. Your financial consultant can help
you decide which class is best for you. For estimated expenses of each class,
see the table under "Fees and Expenses" earlier in this prospectus.

CLASS A SHARES--INITIAL SALES CHARGE
If you purchase Class A shares, you will incur a sales charge at the time of
purchase (a "front-end load") based on the dollar amount of your purchase. The
maximum initial sales charge is 5.50%, which is reduced for purchases of $50,000
and more. Sales charges also may be reduced by using

                                      -13-
<PAGE>


the accumulation privilege described under "Sales Charge Reductions and
Waivers." Class A shares are subject to an ongoing shareholder service fee of
0.25% of the Fund's average net assets attributable to Class A shares. Class A
shares will not be subject to any contingent deferred sales charge (CDSC or
"back end load") when they are redeemed. Although some purchases may not be
subject to an initial sales charge, if the initial sales charge is waived, such
purchases may be subject to a CDSC of 1.00% if the shares are redeemed within
one year after purchase. Class A shares also will be issued upon conversion of
Class B shares, as described below under "Class B Shares." The minimum initial
investment in Class A shares is $2,000.

Part of the front-end sales charge is paid directly to the selling broker-dealer
(the "dealer reallowance"). The remainder is retained by the distributor and may
be used either to promote the sale of the Fund's shares or to compensate the
distributor for its efforts to sell the shares of the Fund.

CLASS B SHARES--DEFERRED SALES CHARGE
If you purchase Class B shares, you will not incur a sales charge at the time of
purchase. However, Class B shares are subject to an ongoing Rule 12b-1
distribution fee of 0.75% of average net assets and an ongoing shareholder
service fee of 0.25% of average net assets. Class B shares are subject to a CDSC
if you redeem them prior to the seventh year after purchase. At the beginning of
the seventh year after purchase, Class B shares will automatically convert into
Class A shares of the Fund, which are subject to the shareholder service fee of
0.25%. Automatic conversion of Class B shares into Class A shares will occur at
least once a month on the basis of the relative net asset values of the shares
of the two classes on the conversion date, without the imposition of any sales
load, fee or other charge. Conversion of Class B shares to Class A shares will
not be deemed a purchase or sale of the shares for federal income tax purposes.
Shares purchased through reinvestment of dividends and other distributions on
Class B shares also will convert automatically to Class A shares based on the
portion of purchased shares that convert. The minimum initial investment in
Class B shares is $2,000.

CLASS C SHARES--PAY AS YOU GO
If you purchase Class C shares, you do not incur a sales charge at the time of
purchase. However, Class C shares are subject to an ongoing Rule 12b-1
distribution fee of 0.75% of average net assets and an ongoing shareholder
service fee of 0.25% of average net assets. Class C shares also are subject to a
1.00% CDSC if you redeem them within 18 months of purchase. Although Class C
shares are subject to a CDSC for only 18 months (as compared to six years for
Class B), Class C shares have no conversion feature. Accordingly, if you
purchase Class C

                                      -14-

shares, those shares will be subject to the 0.75% distribution fee and the 0.25%
shareholder service fee for as long as you own your Class C shares. The minimum
initial investment in Class C shares is $2,000.

You may be subject to a CDSC upon redemption of your Class B and Class C shares
under the following conditions:

         Class B shares will be automatically converted to Class A shares at the
         beginning of the seventh year after purchase.

(BULLET) Class C Shares
   If you redeem Class C shares within 18 months of purchase, you will be
   charged a CDSC of 1.00%. There is no CDSC imposed on Class C shares acquired
   through reinvestment of dividends or capital gains.

The CDSC will be imposed on the lesser of the original purchase price or the net
asset value of the redeemed shares at the time of the redemption. CDSC
calculations are based on the specific shares involved, not the value of the
account. To keep your CDSC as low as possible, each time you place a request to
sell shares, we will first sell any shares in your account that are not subject
to a CDSC. If there are not enough of these shares to meet your request, we will
sell your shares on a first-in, first-out basis. Your financial consultant or
institution may elect to waive some or all of the payment, thereby reducing or
eliminating the otherwise applicable CDSC.

OTHER CLASSES OF SHARES
The Fund also offers other classes of shares for special purposes. These other
classes are not available to the general public, although they may appear in
newspaper listings. When reviewing newspaper listings, please remember that the
class or classes listed may not be the class you own and therefore the net asset
value(s) listed may be different from the net asset value of your shares.

(BULLET)  Accumulation privilege--lets you add the value of shares of any Class
          A shares you and your immediate family already own to the amount of
          your next investment for purposes of calculating sales charges

(BULLET)  Letter of intent--lets you purchase Class A shares over a 13-month
          period and receive the same sales charge as if all shares had been

PURCHASE OF SHARES

Investors may purchase shares of the Fund through financial intermediaries such
as financial consultants, securities brokers, dealers or benefit plan
administrators. Investors should contact their financial intermediary directly
for appropriate purchase instructions, as well as for information pertaining to
accounts and any servicing or transaction fees that may be charged. Some
financial intermediaries may appoint subagents.

The minimum initial investment in Class A, Class B or Class C shares is $2,000
(including IRAs) and $100 for subsequent investments. The adviser or the
distributor, at their discretion, may waive these minimums. See our Statement of
Additional Information for further details.

See "Sales Charge Reductions and Waivers" for ways to make your initial
investment go farther.

Shares are sold at a public offering price based on the net asset value for the
class of shares selected. If your purchase order is received by the Transfer
Agent before the close of regular trading on the Exchange on any Business Day,
you will pay the next public offering price that is determined as of the close
of trading. Purchase orders received after the close of regular trading on the
Exchange will be priced as of the close of regular trading on the following
Business Day.

Any purchase order may be rejected if the Fund determines that accepting the
order would not be in the best interest of the Fund or its shareholders.

                                      -17-
<PAGE>

It is the responsibility of the financial intermediary to transmit orders for
the purchase of shares by its customers to the Transfer Agent and to deliver
required funds on a timely basis, in accordance with the procedures stated
above.

REDEMPTION OF SHARES
         PLAIN TALK
         -----------------------------------------------------------------------
         HOW TO REDEEM (SELL) SHARES:
         (BULLET) By mail
         (BULLET) By telephone
         -----------------------------------------------------------------------

If you purchased your shares through a financial intermediary, you should
contact the intermediary for information relating to redemptions. The Fund's
name and your account number should accompany any redemption requests.

SMALL ACCOUNTS: If the value of your Fund accounts falls below $500, the Fund
may ask you to increase your balance. If the account balance is still below $500
after 60 days, the Fund may close your account and send you the proceeds. The
Fund will not close your account if it falls below $500 solely as a result of a
reduction in your account's market value.

For information on other ways to redeem shares, please refer to our Statement of
Additional Information.

DISTRIBUTIONS
         PLAIN TALK
         -----------------------------------------------------------------------
         WHAT IS NET INVESTMENT INCOME?
         Net investment income consists of interest and dividends earned by a
         fund on its investments less accrued expenses.
         -----------------------------------------------------------------------

Distributions from the net investment income of the Fund are declared and paid
annually to you. Any net capital gain realized by the Fund will be distributed
annually.

Distributions are payable to shareholders of record at the time distributions
are declared (including holders of shares being redeemed, but excluding holders
of shares being purchased). All distributions are reinvested in additional Fund
shares, unless you have elected to receive distributions in cash.

                                      -18-
<PAGE>

TAXES FEDERAL INCOME TAX: As long as the Fund meets the requirements for being a
"regulated  investment  company," it pays no Federal  income tax on the earnings
and  gains  it  distributes  to  shareholders.  While  the Fund  may  invest  in
securities that earn interest  subject to Federal income tax and securities that
earn interest  exempt from that tax,  under normal  conditions  the Fund invests
primarily in taxable  securities.  The Fund will notify you following the end of
the calendar year of the amount of dividends and other  distributions  paid that
year.

Dividends you receive from the Fund, whether reinvested in Fund shares or taken
as cash, are generally taxable to you as ordinary income. The Fund's
distributions of net capital gain, whether received in cash or reinvested in
additional Fund shares, are taxable to you as long-term capital gain, regardless
of the length of time you have held your shares. You should be aware that if
Fund shares are purchased shortly before the record date for any dividend or
capital gain distribution, you will pay the full price for the shares and will
receive some portion of the price back as a taxable distribution. The Fund
anticipates the distribution of net capital gain.

It is a taxable event for you if you sell or exchange shares of the Fund.
Depending on the purchase price and the sale price of the shares you exchange,
you may have a taxable gain or loss on the transaction. You are responsible for
any tax liability generated by your transactions.

STATE AND LOCAL INCOME TAXES: You should consult your tax advisers concerning
state and local taxes, which may have different consequences from those of the
Federal income tax law.

This section is only a summary of some important income tax considerations that
may affect your investment in the Fund. More information regarding those
considerations appears in our Statement of Additional Information. You are urged
to consult your tax adviser regarding the effects of an investment on your tax
situation.

DISTRIBUTION AND SERVICE ARRANGEMENTS
Provident Distributors, Inc. ("PDI") manages the Fund's distribution efforts and
enters into dealer agreements with financial consultants to sell fund shares.

          PLAIN TALK
          ----------------------------------------------------------------------
          HOW CAN YOUR FINANCIAL CONSULTANT HELP YOU?
          Your financial consultant is thoroughly familiar with the Fund and
          with Roxbury Capital Management. He or she can answer any questions
          you have now, or in the future, about how the Fund operates, which
          class of shares is most appropriate for you and how the Roxbury
          investment style works and has performed for other investors. Your
          financial consultant is a valuable and knowledgeable resource.

RULE 12B-1 FEES
          PLAIN TALK
          ----------------------------------------------------------------------
          WHAT ARE 12b-1 FEES?
          12b-1 fees, charged by some funds, are deducted from fund assets to
          pay for marketing and advertising expenses or, more commonly, to
          compensate sales professionals for selling fund shares.
          ----------------------------------------------------------------------

The Fund has adopted a distribution plan under Rule 12b-1 that allows the Fund
to pay a fee to PDI for facilitating the sale and distribution of its shares.
Because these fees are paid out of the Fund's assets on an ongoing basis, over
time these fees indirectly will increase the cost of your investment and may
cost you more than paying other types of sales charges.

Rule 12b-1 permits a fund directly or indirectly to pay expenses associated with
the distribution of its shares and the servicing of its shareholders in
accordance with a plan adopted by the Board of Trustees and approved by its
shareholders. Pursuant to the Rule, the Board has approved, and the Fund has
entered into, a Distribution Plan with PDI, for the Class B and Class C shares.
Under the Distribution Plan, the Fund will pay distribution fees to PDI at a
maximum annual rate of 0.75% of its aggregate average daily net assets
attributable to its Class B and Class C shares.

The Distribution Plan provides that PDI may use the distribution fees received
from a class of shares to pay for the distribution and shareholder servicing
expenses of that class, including, but not limited to (i) incentive compensation
paid to the directors, officers and employees of, agents for and consultants to,
the distributor or any other broker-dealer or financial institution that engages
in the distribution of that class; and (ii) compensation to broker-dealers,
financial institutions or other persons for providing distribution assistance
with respect to that class. Distribution fees may also be used for (i) marketing
and promotional activities, including, but not limited to, direct mail
promotions and television, radio, newspaper, magazine and other mass media
advertising for that class; (ii) costs of printing and distributing
prospectuses, Statements of Additional Information and reports of the Fund to
prospective investors in that class; (iii) costs involved in preparing, printing
and distributing sales literature pertaining to the Fund and that class; and
(iv) costs involved in obtaining whatever information, analysis and reports with
respect to marketing and promotional activities that the Fund may, from time to
time, deem advisable with respect to the distribution of that class.
Distribution fees are accrued daily and paid monthly, and are charged as
expenses of, respectively, Class B and Class C shares as accrued.

The distribution fees applicable to the Class B and Class C shares are designed
to permit you to purchase Class B and Class C shares through broker-dealers
without the assessment of a front-end sales charge and at the same time to
permit the distributor to compensate broker-dealers on an ongoing basis to
provide services to shareholders of the Class B and Class C shares attributable
to those broker-dealers.

                                      -20-
<PAGE>

SHAREHOLDER SERVICE FEES
The Board of Trustees has adopted a shareholder service plan authorizing the
Fund to pay service providers an annual fee not exceeding 0.25% of the Fund's
average daily net assets of each class of shares, to compensate service
providers who maintain a service relationship. Service activities provided under
this plan include (a) establishing and maintaining shareholder accounts and
records, (b) answering shareholder inquiries, (c) assisting in share purchases
and redemptions, (d) providing statements and reports to shareholders, and (e)
providing other related services requested by shareholders.

MASTER /FEEDER STRUCTURE
Other institutional investors, including other mutual funds, may invest in the
Series. The master/feeder structure enables various institutional investors,
including the Fund, to pool their assets, which may be expected to result in
economies by spreading certain fixed costs over a larger asset base. Each
shareholder of a master fund, including the Series, will pay its proportionate
share of the master fund's expenses.

For reasons relating to costs or a change in investment goal, among others, the
Fund could switch to another master fund or decide to manage its assets itself.
The Fund is not currently contemplating such a move.

                                      -21-

                               GENERAL INFORMATION

The Roxbury  Large Cap Growth  Fund (the  "Fund") is part of a mutual fund group
called  WT Mutual  Fund (the  "Trust").  The  Trust is a  diversified,  open-end
management  investment company organized as a Delaware business trust on June 1,
1994.  The name of the Trust was changed  from  Kiewit  Mutual Fund to WT Mutual
Fund on October 20, 1998.

The Fund issues three classes of shares, Class A, Class B, and Class C. The Fund
operates  as a  feeder  fund,  which  means  that  it does  not  buy  individual
securities directly. Instead, it invests in a corresponding master fund with the
same investment objective,  policies and limitations.  The Fund's master fund is
the Large Cap Growth  Series  ("the  "Series")  of WT  Investment  Trust I ("the
Master").

                               INVESTMENT POLICIES

The following  information  supplements  the  information  concerning the Fund's
investment objective,  policies and limitations found in the prospectus.  Unless
otherwise  indicated,  it  applies to the Fund  through  its  investment  in the
Series.  Although the Fund invests  principally  in common  stocks,  it may make
other kinds of investments from time to time.

CASH  MANAGEMENT.  The Fund may  invest in cash and cash  equivalents  including
high-quality  money market instruments and money market funds in order to manage
cash flow in the Fund. Certain of these instruments are described below.

    (BULLET)  MONEY MARKET FUNDS. The Fund may invest in the securities of other
              money market  mutual  funds,  within the limits  prescribed by the
              Investment Company Act of 1940, as amended ("1940 Act").

    (BULLET)  U.S.  GOVERNMENT   OBLIGATIONS.   The  Fund  may  invest  in  debt
              securities  issued  or  guaranteed  by the  U.S.  Government,  its
              agencies or instrumentalities.

    (BULLET)  COMMERCIAL  PAPER.  The  Fund  may  invest  in  commercial  paper.
              Commercial paper consists of short-term (up to 270 days) unsecured
              promissory  notes issued by corporations in order to finance their
              current  operations.  The Fund may invest only in commercial paper
              rated A-1 or higher by S&P or Moody's or if not rated,  determined
              by the adviser to be of comparable quality.

    (BULLET)  BANK OBLIGATIONS.  The Fund may invest in U.S.  dollar-denominated
              obligations of major banks,  including  certificates  of deposits,
              time deposits and bankers'  acceptances  of major U.S. and foreign
              banks and their branches located outside of the United States,  of
              U.S.  branches of foreign  banks,  of foreign  branches of foreign
              banks,  of U.S.  agencies  of  foreign  banks and of  wholly-owned
              banking subsidiaries of such foreign banks located in the U. S.

CONVERTIBLE  SECURITIES.  Convertible securities have characteristics similar to
both fixed income and equity securities.  Because of the conversion feature, the
market value of  convertible  securities  tends to move together with the market
value of the underlying stock. As a result,  the Fund's selection of convertible
securities  is  based,  to  a  great  extent,   on  the  potential  for  capital
appreciation  that may exist in the underlying  stock.  The value of convertible
securities is also affected by prevailing  interest rates, the credit quality of
the issuers and any call provisions.

The Fund may invest in  convertible  securities  that are rated,  at the time of
purchase,  in the three highest  rating  categories  by a nationally  recognized
statistical  rating  organization  such as Moody's or S&P,  or if  unrated,  are
determined  by  the  adviser  to be  of  comparable  quality.  (See  Appendix  B
"Description  of  Ratings").  Should  the  rating of a  security  be  downgraded
subsequent to the Fund's purchase of the security,  the adviser,  as applicable,
will  determine  whether  it is in the best  interest  of the Fund to retain the
security.

DEBT  SECURITIES.  Debt  securities  represent money borrowed that obligates the
issuer (e.g., a corporation,  municipality,  government,  government  agency) to
repay the borrowed  amount at maturity  (when the obligation is due and payable)
and usually to pay the holder interest at specific times.

                                                                               3

HEDGING  STRATEGIES.  The Fund may engage in  certain  hedging  strategies  that
involve options and futures. These hedging strategies are described in detail in
Appendix A.

ILLIQUID  SECURITIES.  The Fund may invest no more than 15% of its net assets in
securities  that at the time of purchase have legal or contractual  restrictions
on resale or are otherwise  illiquid.  If the limitations on illiquid securities
are exceeded,  other than by a change in market  values,  the condition  will be
reported by the adviser to the Board of Trustees.

OPTIONS ON SECURITIES AND SECURITIES INDEXES. The Fund may purchase call options
on  securities  that the adviser  intends to include in the Fund in order to fix
the cost of a future  purchase  or attempt to  enhance  return by, for  example,
participating  in an anticipated  increase in the value of a security.  The Fund
may  purchase  put  options to hedge  against a decline  in the market  value of
securities  held in the Fund or in an attempt to  enhance  return.  The Fund may
write  (sell)  put and  covered  call  options on  securities  in which they are
authorized to invest. The Fund may also purchase put and call options, and write
put and covered call options on U.S.  securities  indexes.  Stock index  options
serve to hedge against  overall  fluctuations  in the securities  markets rather
than anticipated  increases or decreases in the value of a particular  security.
Of the  percentage  of the total  assets of the Fund that are invested in equity
(or related) securities, the Fund may not invest more than 10% of such assets in
covered call options on securities and/or options on securities indices.

REPURCHASE  AGREEMENTS.   The  Fund  may  invest  in  repurchase  agreements.  A
repurchase  agreement is a transaction in which a Fund purchases a security from
a bank or recognized securities dealer and simultaneously commits to resell that
security  to a bank or dealer at an agreed  date and price  reflecting  a market
rate of interest,  unrelated to the coupon rate or the maturity of the purchased
security.   While  it  is  not  possible  to  eliminate  all  risks  from  these
transactions  (particularly  the possibility of a decline in the market value of
the underlying securities,  as well as delays and costs to the Fund if the other
party to the repurchase  agreement  becomes  bankrupt),  it is the policy of the
Fund to limit  repurchase  transactions  to  primary  dealers  and  banks  whose
creditworthiness  has been  reviewed  and  found  satisfactory  by the  adviser.
Repurchase  agreements  maturing in more than seven days are considered illiquid
for purposes of the Fund's investment limitations.

RESTRICTED SECURITIES. Restricted securities are securities that may not be sold
to the public without registration under the Securities Act of 1933 ("1933 Act")
or an exemption from registration.  Restricted securities,  including securities
eligible for re-sale under 1933 Act Rule 144A,  that are determined to be liquid
are not  subject to this  limitation.  This  determination  is to be made by the
adviser  pursuant to  guidelines  adopted by the Board of Trustees.  Under these
guidelines, the adviser will consider the frequency of trades and quotes for the
security,   the  number  of  dealers  in,  and  potential  purchasers  for,  the
securities, dealer undertakings to make a market in the security, and the nature
of the security and of the  marketplace  trades.  In purchasing  such restricted
securities,  the  adviser  intends to purchase  securities  that are exempt from
registration under Rule 144A under the 1933 Act.

SECURITIES LENDING.  The Fund may lend securities pursuant to agreements,  which
require that the loans be  continuously  secured by collateral  equal to 100% of
the market value of the loaned  securities.  Such  collateral  consists of cash,
securities of the U.S.  Government or its agencies,  or any  combination of cash
and such securities.  Such loans will not be made if, as a result, the aggregate
amount of all outstanding securities loans for the Fund exceeds one-third of the
value of the Fund's  total  assets  taken at fair  market  value.  The Fund will
continue to receive interest on the securities lent while simultaneously earning
interest on the investment of the cash collateral in U.S. Government securities.
However,  the Fund will  normally  pay lending fees to such  broker-dealers  and
related expenses from the interest earned on invested  collateral.  There may be
risks of delay in receiving additional  collateral or risks of delay in recovery
of the securities and even loss of rights in the collateral  should the borrower
of the securities fail  financially.  However,  loans are made only to borrowers
deemed by the adviser to be of good  standing  and when,  in the judgment of the
adviser,  the  consideration  that can be earned  currently from such securities
loans justifies the attendant risk.  Either party upon reasonable  notice to the
other party may terminate any loan.

                             INVESTMENT LIMITATIONS

Except  as  otherwise  provided,  the  Fund  and the  Series  have  adopted  the
investment  limitations  set forth below.  Limitations  which are  designated as
fundamental  policies  may not be changed  without the  affirmative  vote of the

                                                                               4

meeting if holders  of more than 50% of the  outstanding  shares of the Fund are
present in person or by proxy or (ii) more than 50% of the outstanding shares of
the Fund. If any  percentage  restriction on investment or utilization of assets
is adhered to at the time an  investment  is made, a later change in  percentage
resulting from a change in the market values of the Fund's assets or redemptions
of shares will not be considered a violation of the limitation.

The Fund will not as a matter of fundamental policy:

1.   purchase the  securities of any one issuer, if as a result, more than 5% of
the Fund's total assets would be invested in the  securities of such issuer,  or
the Fund would own or hold 10% or more of the outstanding  voting  securities of
that issuer, provided that (1) the Fund may invest up to 25% of its total assets
without  regard  to these  limitations;  (2) these  limitations  do not apply to
securities  issued  or  guaranteed  by the  U.S.  Government,  its  agencies  or
instrumentalities;  and (3) repurchase  agreements fully  collateralized by U.S.
Government obligations will be treated as U.S. Government obligations;

2.  purchase  securities  of any  issuer  if, as a result,  more than 25% of the
Fund's total assets would be invested in the  securities  of one or more issuers
having their principal business activities in the same industry,  provided, that
this limitation does not apply to debt  obligations  issued or guaranteed by the
U.S. Government, its agencies or instrumentalities;

3.  borrow  money, provided  that the Fund may borrow  money for  temporary  or
emergency purposes,  and then in an aggregate amount not in excess of 10% of the
Fund's total assets;

4.  make loans to other persons, except by (1)  purchasing  debt  securities in
accordance with its investment objective, policies and limitations; (2) entering
into repurchase agreements; or (3) engaging in securities loan transactions;

5.  underwrite any issue of securities, except to the extent that the Fund may
be considered to be acting as underwriter in connection with the disposition of
any portfolio security;

6.  purchase or sell  real  estate,  provided  that  the  Fund  may  invest  in
obligations secured by real estate or interests therein or obligations issued by
companies that invest in real estate or interests therein, including real estate
investment trusts;

7.  purchase or sell physical commodities, provided that the Fund may invest in,
purchase,  sell or enter into  financial  options and futures,  forward and spot
currency   contracts,   swap   transactions  and  other   derivative   financial
instruments; or

8.  issue senior securities, except to the extent permitted by the 1940 Act.

THE  INVESTMENT  LIMITATIONS  DESCRIBED  ABOVE DO NOT  PROHIBIT  THE  FUND  FROM
INVESTING  ALL OR  SUBSTANTIALLY  ALL OF ITS  ASSETS IN THE  SHARES  OF  ANOTHER
REGISTERED OPEN-END INVESTMENT COMPANY SIMILAR TO ITS SERIES.

The following  non-fundamental  policies apply to the Fund and may be changed by
the Board of Trustees without shareholder approval. The Fund will not:

1.  make short sales of securities except as described in the prospectus;

2.  purchase  securities  on  margin  except  for the use of  short-term  credit
necessary for the clearance of purchases and sales of portfolio securities;

3.  purchase portfolio securities if its outstanding borrowings exceed 5% of the
value of its total assets.

                                                                               5

                     INVESTMENT ADVISORY AND OTHER SERVICES

ADVISORY SERVICES
Roxbury Capital Management,  LLC serves as the investment adviser to the Series.
The Series pays a monthly advisory fee to Roxbury at the annual rate of 0.55% of
the Series' first $1 billion of average  daily net assets;  0.50% of the Series'
next $1 billion of average  daily net assets;  and 0.45% of the Series'  average
daily net assets over $2 billion.

Roxbury has agreed to waive a portion of its advisory fee or reimburse  expenses
to the extent total operating  expenses,  as a percentage of average net assets,
exceed  1.30% for the Fund's  Class A shares,  and 2.05% for Class B and Class C
shares.  This  undertaking  will  remain in place  until  the Board of  Trustees
approves its termination.

Under the terms of the advisory agreement, the adviser agrees to: (a) direct the
investments  of the  Series,  subject  to and in  accordance  with  the  Series'

Trustees and officers of the Fund for consultation and discussion  regarding the
management  of the  Series  and its  investment  activities.  Additionally,  the
adviser agrees to create and maintain all necessary  records in accordance  with
all applicable laws, rules and regulations  pertaining to the various  functions
performed  by it and not  otherwise  created  and  maintained  by another  party
pursuant to contract with the Fund.  The adviser may at any time or times,  upon
approval  by  the  Board  of  Trustees,  enter  into  one or  more  sub-advisory
agreements with a sub-adviser pursuant to which the adviser delegates any or all
of its duties as listed.

The  agreement  provides  that the adviser  shall not be liable for any error of
judgment or mistake of law or for any loss  suffered by the Series in connection
with the matters to which the agreement relates,  except to the extent of a loss
resulting from willful misfeasance, bad faith or gross negligence on its part in
the performance of its obligations and duties under the agreement.

The salaries of any officers and Trustees of the Trust who are  affiliated  with
the adviser and the salaries of all personnel of the adviser performing services
for the Fund relating to research,  statistical  and  investment  activities are
paid by the adviser.

                   DISTRIBUTION OF SHARES AND RULE 12B-1 PLAN

Provident  Distributors,   Inc.,  ("PDI")  Four  Falls  Corporate  Center,  West
Conshohocken,  PA 19428, serves as the underwriter of the Fund's shares pursuant
to a  Distribution  Agreement  with  the  Trust.  Pursuant  to the  terms of the
Distribution Agreement,  PDI is granted the right to sell the shares of the Fund
as agent for the Fund. Shares of the Fund are offered continuously.

Under the terms of the Distribution Agreement,  PDI agrees to use all reasonable
efforts to secure  purchasers  for Class B and Class C shares of the Fund and to
pay expenses of printing and distributing prospectuses, statements of additional
information and reports  prepared for use in connection with the sale of Class B
and Class C shares of the Fund and any other  literature and advertising used in
connection with the offering,  out of the  compensation it receives  pursuant to
the Fund's Plan of  Distribution  adopted  pursuant to Rule 12b-1 under the 1940
Act (the "12b-1 Plan").  PDI receives no underwriting  commissions or Rule 12b-1
fees in connection with the sale of the Fund's Class A shares.

The  Distribution  Agreement  provides  that  PDI,  in the  absence  of  willful
misfeasance,  bad faith or gross  negligence in the performance of its duties or
by  reason  of  reckless  disregard  of its  obligations  and  duties  under the
Agreement, will not be liable to the Fund or its shareholders for losses arising
in connection with the sale of Fund shares.

The Distribution Agreement became effective as of November 1, 1999 and continues
in effect for a period of two years.  Thereafter,  the agreement may continue in
effect for successive  annual periods  provided such  continuance is approved at
least  annually  by a majority  of the  Trustees,  including  a majority  of the
Independent Trustees. The Distribution Agreement terminates automatically in the
event of an assignment.  The agreement is also terminable without payment of any
penalty  with  respect to the Fund (i) (by vote of a majority of the Trustees of
the Trust who are not interested  persons of the Trust and who have no direct or
indirect  financial interest in the operation of any Rule 12b-1 Plan of the Fund
or any  agreements  related to a 12b-1  Plan,  or by vote of a  majority  of the
outstanding  voting  securities  of the  applicable  Fund) on sixty  (60)  days'
written  notice to PDI; or (ii) by PDI on sixty (60) days' written notice to the
Trust.

PDI will be compensated for distribution  services  according to the Class B and
Class C 12b-1 Plans,  which became effective on November 1, 1999,  regardless of
PDI's  expenses.  The Class B and Class C 12b-1 Plans  provide  that PDI will be
paid for distribution  activities such as public relations  services,  telephone
services, sales presentations,  media charges, preparation, printing and mailing
advertising  and  sales  literature,  data  processing  necessary  to  support a
distribution  effort and printing  and mailing of  prospectuses  to  prospective
shareholders.  Additionally,  PDI may pay certain financial institutions such as
banks or  broker-dealers  who have entered into  servicing  agreements  with PDI
("Service  Organizations") and other financial institutions for distribution and
shareholder servicing activities.

When purchasing  Class A shares,  a sales charge will be incurred at the time of
purchase (a "front-end  load") based on the dollar  amount of the purchase.  The
maximum initial sales charge is 5.50%, which is reduced for purchases of

                                                                               9

<PAGE>

$50,000 and more.  Sales  charges also may be reduced by using the  accumulation
privilege  described  under  "Sales  Charge  Reductions  and  Waiver".  Although
purchases of  $1,000,000  or more may not be subject to an initial sales charge,
if the initial sales charge is waived,  such  purchases may be subject to a CDSC
of 1.00% if the shares are redeemed within one year after purchase.

Part of the front-end sales charge is paid directly to the selling broker-dealer
(the  "dealer  reallowance").  The  remainder is retained by PDI and may be used
either to promote  the sale of the Fund's  shares or to  compensate  PDI for its
efforts to sell the shares of the Fund.

The Class B and Class C 12b-1 Plans  further  provide that payment shall be made
for any month only to the extent that such  payment does not exceed (i) 0.75% on
an annualized  basis of the respective  Class B and Class C shares'  average net
assets; and (ii) limitations set from time to time by the Board of Trustees.

Under the Class B and Class C 12b-1 Plans,  if any payments  made by the adviser
out of its  advisory  fee,  not to exceed the  amount of that fee,  to any third
parties  (including  banks),  including  payments for shareholder  servicing and
transfer agent  functions,  were deemed to be indirect  financing by the Fund of
the  distribution of its shares,  such payments are  authorized.  The Series may
execute portfolio transactions with and purchase securities issued by depository
institutions  that receive  payments  under the 12b-1 Plans.  No preference  for
instruments issued by such depository  institutions is shown in the selection of
investments.

                    BROKERAGE ALLOCATION AND OTHER PRACTICES

The adviser places all portfolio  transactions on behalf of the Series. Any debt
securities  purchased and sold by the Master are generally  traded on the dealer
market on a net basis (i.e.,  without  commission)  through  dealers  acting for
their own account and not as brokers, or otherwise involve transactions directly
with the issuer of the instrument. This means that a dealer (the securities firm
or bank dealing with a Series) makes a market for  securities by offering to buy
at one price and sell at a slightly  higher price.  The  difference  between the
prices is known as a spread.  When  securities  are  purchased  in  underwritten
offerings, they include a fixed amount of compensation to the underwriter.

The primary  objective of the adviser in placing  orders on behalf of the Series
for the purchase and sale of securities is to obtain best  execution at the most
favorable prices through responsible brokers or dealers and, where the spread or
commission rates are negotiable,  at competitive rates. In selecting a broker or
dealer,  the  adviser  considers,  among  other  things:  (i) the  price  of the
securities to be purchased or sold;  (ii) the rate of the spread or  commission;
(iii) the size and difficulty of the order; (iv) the nature and character of the
spread  or  commission  for the  securities  to be  purchased  or sold;  (v) the
reliability,  integrity,  financial condition, general execution and operational
capability  of the broker or dealer;  and (vi) the  quality of any  research  or
statistical  services  provided  by the broker or dealer to the Series or to the
adviser.

The adviser cannot  readily  determine the extent to which spreads or commission
rates or net prices  charged by  brokers or dealers  reflect  the value of their
research,  analysis,  advice and similar  services.  In such cases,  the adviser
receives  services it otherwise might have had to perform itself.  The research,
analysis,  advice and  similar  services  provided  by brokers or dealers can be
useful to the  adviser in serving its other  clients,  as well as in serving the
Series.  Conversely,  information  provided to the adviser by brokers or dealers
who have executed  transaction  orders on behalf of other clients of the adviser
may be useful in providing services to the Series.

                                                                              10
<PAGE>

Some of the adviser's other clients may have investment  objectives and programs
similar  to that of the  Series.  Occasionally,  recommendations  made to  other
clients may result in their purchasing or selling securities simultaneously with
the Series.  Consequently,  the demand for  securities  being  purchased  or the
supply of  securities  being sold may  increase,  and this could have an adverse
effect on the price of those securities.  It is the policy of the adviser not to
favor one client over another in making recommendations or in placing orders. In
the event of a simultaneous  transaction,  purchases or sales are averaged as to
price,  transaction  costs  are  allocated  between a Series  and other  clients
participating in the transaction on a pro rata basis and purchases and sales are
normally  allocated  between  the  Series  and the  other  clients  as to amount
according to a formula determined prior to the execution of such transactions.

                       CAPITAL STOCK AND OTHER SECURITIES

The Trust issues three separate classes of shares, Class A, Class B, and Class C
shares  of the  Fund.  The  shares  of the  Fund,  when  issued  and paid for in
accordance with the prospectus,  will be fully paid and  non-assessable  shares,
with  equal  voting  rights  and  no  preferences  as to  conversion,  exchange,
dividends, redemption or any other feature.

The separate classes of shares each represent interests in the same portfolio of
investments, have the same rights and are identical in all respects, except that
(1) Class A shares  bear a  shareholder  service fee of 0.25% of the average net
assets  of Class A shares  and (2) Class B and  Class C shares  bear Rule  12b-1
distribution expenses of 0.75% of the average net assets of the respective Class
B and Class C shares and have  exclusive  voting rights with respect to the Rule
12b-1  Plan  pursuant  to which the Rule  12b-1 fee may be paid.  The net income
attributable to a class of shares and the dividends  payable on such shares will
be  reduced  by the  amount  of any  shareholder  service  or Rule  12b-1  fees;
accordingly,  the net asset value of Class A, Class B and Class C shares will be
reduced by such amount to the extent the Fund has undistributed net income.

Shares of the Fund entitle  holders to one vote per share and  fractional  votes
for fractional  shares held.  Shares have  non-cumulative  voting rights, do not
have preemptive or subscription  rights and are transferable.  The Fund and each
class takes separate votes on matters affecting only the Fund or that class. For
example, a change in the fundamental  investment  policies for the Fund would be
voted upon by all shareholders of the Fund.

The Fund  does not hold  annual  meetings  of  shareholders.  The  Trustees  are
required  to call a meeting of  shareholders  for the purpose of voting upon the
question of removal of any  Trustee  when  requested  in writing to do so by the
shareholders  of  record  owning  not less  than 10% of the  Fund's  outstanding
shares.

                   PURCHASE, REDEMPTION AND PRICING OF SHARES

PURCHASE OF SHARES.

BY MAIL: You or your  financial  intermediary  may purchase  shares by sending a
check drawn on a U.S. bank payable to Roxbury Large Cap Growth Fund,  along with
a completed application (included at the end of the prospectus). If a subsequent
investment  is being made,  the check  should also  indicate  your Fund  account
number.  When you make  purchases  by check,  the Fund may  withhold  payment on
redemptions until it is reasonably satisfied that the funds are collected (which
can take up to 10  days).  If you  purchase  shares  with a check  that does not
clear, your purchase will be canceled and you will be responsible for any losses
or fees incurred in that transaction. Send the check and application to:

purchase, to also obtain an account number.

                                                                              11

INDIVIDUAL  RETIREMENT  ACCOUNTS:  You may  purchase  shares  of the  Fund for a
tax-deferred  retirement plan such as an individual  retirement account ("IRA").
To order an  application  for an IRA and a brochure  describing a Fund IRA, call
PFPC at (800)  497-2960.  PFPC Trust Company,  as custodian for each IRA account
receives an annual fee of $10 per account,  paid  directly to PFPC Trust Company
by the IRA shareholder.  If the fee is not paid by the due date, the appropriate
number  of Fund  shares  owned  by the IRA  will be  redeemed  automatically  as
payment.

AUTOMATIC  INVESTMENT  PLAN:  You may purchase Fund shares  through an Automatic
Investment  Plan  ("AIP").  Under the AIP,  PFPC,  at  regular  intervals,  will
automatically  debit  your  bank  checking  account  in an amount of $50 or more
(after  the  $2,000  minimum  initial  investment).  You may elect to invest the
specified amount monthly,  bimonthly,  quarterly,  semiannually or annually. The
purchase of Fund shares will be effected at their offering price at the close of
regular  trading on the New York Stock  Exchange  ("Exchange")  (currently  4:00
p.m.,  Eastern  time),  on or about  the 20th day of the  month.  To  obtain  an
application for the AIP, call the Transfer Agent at (800) 497-2960.

PAYROLL INVESTMENT PLAN: The Payroll Investment Plan ("PIP") permits you to make
regularly scheduled purchases of Fund shares through payroll deductions. To open
a PIP  account,  you  must  submit  a  completed  account  application,  payroll
deduction  form and the  minimum  initial  deposit  to your  employer's  payroll
department.  Then, a portion of your paycheck will  automatically be transferred
to your PIP account for as long as you wish to  participate  in the plan.  It is
the sole  responsibility  of your employer,  not the Fund, the distributor,  the
adviser or the transfer  agent, to arrange for  transactions  under the PIP. The
Fund reserves the right to vary its minimum purchase  requirements for employees
participating in a PIP.

REDEMPTION OF SHARES.

You or your financial  intermediary  may sell your shares on any Business Day as
described  below.  Redemptions are effected at the NAV next determined after the
Transfer Agent has received your redemption request. It is the responsibility of
your  financial  intermediary  to  transmit  redemption  orders and credit  your
account with redemption proceeds on a timely basis. Redemption checks are mailed
on the next Business Day following  receipt by the Transfer  Agent of redemption
instructions,  but never  later  than 7 days  following  such  receipt.  Amounts
redeemed  by wire  are  normally  wired  on the date of  receipt  of  redemption
instructions  (if received by the Transfer Agent before 4:00 p.m. Eastern time),
or the next  Business Day (if received  after 4:00 p.m.  Eastern  time,  or on a
non-Business Day), but never later than 7 days following such receipt.

BY  MAIL:  If you  redeem  your  shares  by  mail,  you  should  submit  written
instructions with a "signature  guarantee." A signature  guarantee  verifies the
authenticity  of  your   signature.   You  can  obtain  one  from  most  banking
institutions  or  securities  brokers,  but not from a Notary  Public.  You must
indicate  the Fund  name,  your  account  number  and  your  name.  The  written
instructions and signature guarantee should be mailed to:

BY TELEPHONE:  If you prefer to redeem your shares by telephone you may elect to
do so.  However there are certain  risks.  The Fund has certain  safeguards  and
procedures  to  confirm  the  identity  of  callers  and  to  confirm  that  the
instructions communicated are genuine. If such procedures are followed, you will
bear the risk of any losses.

BY WIRE:  Redemption proceeds may be wired to your predesignated bank account in
any  commercial  bank in the United States if the amount is $1,000 or more.  The
receiving bank may charge a fee for this service. Proceeds may also be mailed to
your bank or,  for  amounts  of  $10,000  or less,  mailed to your Fund  account
address of record if the address has been  established  for at least 60 days. In
order to authorize the Transfer Agent to mail  redemption  proceeds to your Fund
account address of record,  complete the appropriate  section of the Application
for Telephone  Redemptions  or include your Fund account  address of record when
you  submit  written  instructions.  You may change  the  account  that you have
designated to receive  amounts  redeemed at any time.  Any request to change the
account  designated to receive  redemption  proceeds  should be accompanied by a
guarantee of the shareholder's

                                                                              12

signature by an eligible institution.  A signature and a signature guarantee are
required  for each  person in whose  name the  account  is  registered.  Further
documentation  will  be  required  to  change  the  designated  account  when  a
corporation,  other  organization,   trust,  fiduciary  or  other  institutional
investor holds the Fund shares.

SYSTEMATIC  WITHDRAWAL  PLAN:  If you own Fund shares with a value of $10,000 or
more you may participate in the Systematic  Withdrawal  Plan ("SWP").  Under the
SWP, you may automatically redeem a portion of your account monthly,  bimonthly,
quarterly,  semiannually or annually.  The minimum withdrawal available is $100.
All the redemptions,  including  bi-monthly  redemptions of Fund shares, will be
effected at the NAV determined on or about the 25th day of the month.

ADDITIONAL INFORMATION REGARDING REDEMPTIONS: If shares to be redeemed represent
a recent  investment made by check,  the Fund reserves the right not to make the
redemption  proceeds  available until it has reasonable  grounds to believe that
the check has been collected (which could take up to 10 days).

To ensure proper  authorization before redeeming Fund shares, the Transfer Agent
may require  additional  documents such as, but not restricted to, stock powers,
trust instruments, death certificates,  appointments as fiduciary,  certificates
of corporate  authority and waivers of tax required in some states when settling
estates.

When shares are held in the name of a corporation,  other  organization,  trust,
fiduciary or other  institutional  investor,  the Transfer  Agent  requires,  in
addition  to the  stock  power,  certified  evidence  of  authority  to sign the
necessary  instruments of transfer.  THESE  PROCEDURES ARE FOR THE PROTECTION OF
SHAREHOLDERS  AND  SHOULD BE  FOLLOWED  TO  ENSURE  PROMPT  PAYMENT.  Redemption
requests must not be conditional as to date or price of the redemption. Proceeds
of a redemption  will be sent within 7 days of acceptance of shares tendered for
redemption.  Delay may result if the purchase check has not yet cleared, but the
delay will be no longer  than  required to verify  that the  purchase  check has
cleared, and the Fund will act as quickly as possible to minimize delay.

The value of shares  redeemed  may be more or less than your cost,  depending on
the net asset value at the time of  redemption.  Redemption of shares may result
in tax consequences  (gain or loss) to you, and the proceeds of a redemption may
be subject to backup withholding.

Your right to redeem  shares and to receive  payment  therefore may be suspended
when (a) the  Exchange  is closed,  other than  customary  weekend  and  holiday
closings, (b) trading on the Exchange is restricted,  (c) an emergency exists as
a result of which it is not  reasonably  practicable  to  dispose  of the Fund's
securities or to determine the value of the Fund's net assets, or (d) ordered by
a governmental body having  jurisdiction over the Fund for the protection of the
Fund's  shareholders,  provided that applicable rules and regulations of the SEC
(or  any  succeeding  governmental  authority)  shall  govern  as to  whether  a
condition  described in (b), (c) or (d) exists. In case of such suspension,  you
may withdraw a request for  redemption  or may receive  payment based on the net
asset value of the Fund next determined after the suspension is lifted.

The Fund  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 with readily marketable  securities chosen by the Fund and valued in the
same way as they would be valued for purposes of  computing  the net asset value
of the  Fund.  If  payment  is made in  securities,  you may  incur  transaction
expenses  in  converting  these  securities  into  cash.  The Fund has  elected,
however,  to be  governed by Rule 18f-1 under the 1940 Act, as a result of which
the Fund is obligated to redeem shares solely in cash if the redemption requests
are made by one  shareholder  account up to the lesser of  $250,000 or 1% of the
net assets of the Fund during any 90-day  period.  This election is  irrevocable
unless the SEC permits its withdrawal.

PRICING OF SHARES

The net asset value per share of the Fund is determined by dividing the value of
the Fund's  net  assets by the total  number of Fund  shares  outstanding.  This
determination  is made by  PFPC,  as of the  close  of  regular  trading  on the
Exchange  (currently  4:00  p.m.,  Eastern  time)  each day the Fund is open for
business. The Fund is open for business on days when the Exchange,  PFPC and the
Philadelphia  branch  office  of the  Federal  Reserve  are  open  for  business
("Business Day").

In valuing the Fund's assets, a security listed on the Exchange (and not subject
to restrictions  against sale by the Fund on the Exchange) will be valued at its
last sale price on the Exchange on the day the  security is valued.  Lacking any
sales on such day, the  security  will be valued at the mean between the closing
asked price and the closing bid price. Securities listed on other exchanges (and
not subject to restriction  against sale by the Fund on

                                                                              13
<PAGE>

such exchanges) will be similarly  valued,  using  quotations on the exchange on
which the  security is traded most  extensively.  Unlisted  securities  that are
quoted on the  National  Association  of  Securities  Dealers'  National  Market
System, for which there have been sales of such securities on such day, shall be
valued at the last sale price reported on such system on the day the security is
valued.  If there  are no such  sales on such day,  the value  shall be the mean
between  the closing  asked  price and the closing bid price.  The value of such
securities  quoted on the  NASDAQ  Stock  Market  System,  but not listed on the
National  Market  System,  shall be valued at the mean between the closing asked
price and the closing bid price.  Unlisted securities that are not quoted on the
NASDAQ Stock Market System and for which over-the-counter  market quotations are
readily  available  will be valued at the mean between the current bid and asked
prices  for  such  security  in  the  over-the-counter  market.  Other  unlisted
securities (and listed securities subject to restriction on sale) will be valued
at fair value as  determined  in good faith under the  direction of the Board of
Trustees  although  the actual  calculation  may be done by  others.  Short-term
investments  with  remaining  maturities  of less  than 61 days  are  valued  at
amortized cost.

                                    DIVIDENDS

Dividends  from the  Fund's  net  investment  income  and  distributions  of net
short-term  capital  gain and net  capital  gain (the  excess  of net  long-term
capital  gain over the  short-term  capital  loss)  realized by the Fund,  after
deducting any  available  capital loss  carryovers  are declared and paid to its
shareholders annually.

                              TAXATION OF THE FUND

GENERAL.  The Fund is treated as a separate  corporation  for federal income tax
purposes.  To qualify  or  continue  to qualify  for  treatment  as a  regulated
investment  company ("RIC") under the Internal  Revenue Code of 1986, as amended
(the "Code"), the Fund must distribute to its shareholders for each taxable year
at least 90% of its investment company taxable income  (consisting  generally of
net  investment  income and net  short-term  capital  gain and must meet several
additional requirements. For the Fund, these requirements include the following:
(1) the Fund must derive at least 90% of its gross income each taxable year from
dividends,  interest,  payments with respect to securities  loans and gains from
the sale or other  disposition  of  securities or foreign  currencies,  or other
income  (including gains from options,  futures and forward  contracts)  derived
with respect to its business of investing in securities or those currencies; (2)
at the close of each  quarter of the Fund's  taxable  year,  at least 50% of the
value of its total  assets  must be  represented  by cash and cash  items,  U.S.
Government securities, securities of other RICs and other securities, with these
other securities  limited,  in respect of any one issuer, to an amount that does
not  exceed  5% of the  value of the  Fund's  total  assets  and  that  does not
represent more than 10% of the issuer's  outstanding voting securities;  and (3)
at the close of each quarter of the Fund's  taxable  year,  not more than 25% of
the value of its total assets may be invested in securities (other than U.S.
Government securities or the securities of other RICs) of any one issuer.

If the Fund failed to qualify for  treatment  as a RIC in any taxable  year,  it
would be  subject  to tax on its  taxable  income  at  corporate  rates  and all
distributions  from earnings and profits,  including any distributions  from net
capital  gain (the  excess of net  long-term  capital  gain over net  short-term
capital  loss),  would be taxable to its  shareholders  as ordinary  income.  In
addition,  the  Fund  could be  required  to  recognize  unrealized  gains,  pay
substantial  taxes  and  interest  and  make  substantial  distributions  before
qualifying again for RIC treatment.

The Fund will be subject to a nondeductible 4% excise tax to the extent it fails
to distribute by the end of any calendar year  substantially all of its ordinary
income for that year and capital gain net income for the one-year  period ending
on October 31 of that year, plus certain other amounts.

Dividends and other distributions  declared by the Fund in October,  November or
December of any year and payable to  shareholders  of record on a date in one of
those months will be deemed to have been paid by the Fund and received by you on
December  31 of that  year if they  are paid by the Fund  during  the  following
January.  Accordingly,  such  distributions will be taxed to you for the year in
which that December 31 falls.

You should be aware that if Fund shares are purchased  shortly before the record
date for any dividend (other than an  exempt-interest  dividend) or capital gain
distribution,  you will pay full  price for the  shares  and will  receive  some
portion of the price back as a taxable distribution.

                                                                              14

<PAGE>

If the Fund makes a distribution  to  shareholders  in excess of its current and
accumulated  earnings and profits in any taxable year,  the excess  distribution
will be  treated  by you as a return of  capital to the extent of your tax basis
and thereafter as capital gain.

It is anticipated that all or a portion of the dividends from the net investment
income of the Fund will qualify for the dividends-received  deduction allowed to
corporations.  The  qualifying  portion may not exceed the  aggregate  dividends
received by the Fund from U.S.  corporations.  However,  dividends received by a
corporate  shareholder  and  deducted by it  pursuant to the  dividends-received
deduction  are  subject  indirectly  to the  federal  alternative  minimum  tax.
Moreover,  the  dividends-received  deduction  will be reduced to the extent the
shares  with  respect  to which  the  dividends  are  received  are  treated  as
debt-financed  and will be  eliminated  if those  shares are deemed to have been
held for less than 46 days. Distributions of net short-term capital gain and net
capital gain are not eligible for the dividends-received deduction.

Any loss realized by you on the  redemption of shares within six months from the
date of their purchase will be treated as a long-term,  instead of a short-term,
capital loss to the extent of any capital gain distributions to you with respect
to those shares.

HEDGING TRANSACTIONS.  The use of hedging strategies,  such as writing (selling)
and purchasing  options and futures contracts and entering into forward currency
contracts,  involves  complex rules that will  determine for federal  income tax
purposes the amount, character and timing of recognition of the gains and losses
the Fund realizes in connection therewith. Gains from the disposition of foreign
currencies (except certain gains that may be excluded by future regulations) and
gains from options,  futures and foreign currency  contracts derived by the Fund
with respect to its business of investing in securities  qualify as  permissible
income under the Income Requirement.

Futures and foreign  currency  contracts that are subject to section 1256 of the
Code (other than such contracts that are part of a "mixed straddle" with respect
to which the Fund has made an election  not to have the  following  rules apply)
("Section  1256  Contracts")  and  that  are  held by the Fund at the end of its
taxable year generally will be "marked-to-market"  (that is, deemed to have been
sold for their market value) for federal  income tax purposes.  Sixty percent of
any net  gain or loss  recognized  on  these  deemed  sales,  and 60% of any net
realized gain or loss from any actual sales of Section 1256  Contracts,  will be
treated as long-term  capital  gain or loss,  and the balance will be treated as
short-term  capital gain or loss. As of the date of this Statement of Additional
Information,  it is not entirely clear whether that 60% portion will qualify for
the  reduced  maximum tax rates on  non-corporate  taxpayers'  net capital  gain
enacted by the Taxpayer  Relief Act of 1997 -- 20% (10% for taxpayers in the 15%
marginal tax bracket) for gain  recognized on capital  assets held for more than
18 months -- instead of the 28% rate in effect  before that  legislation,  which
now applies to gain recognized on capital assets held for more than one year but
not more than 18 months. However, technical correction legislation passed by the
House of Representatives  late in 1997 would clarify that the lower rates apply.
Section 1256 Contracts also may be  marked-to-market  for purposes of the Excise
Tax.

Code  section  1092  (dealing  with  straddles)  also may affect the taxation of
options and futures contracts in which the Fund may invest. Section 1092 defines
a "straddle"  as offsetting  positions  with respect to personal  property;  for
these  purposes,  options and futures  contracts  are personal  property.  Under
section  1092,  any loss  from  the  disposition  of a  position  in a  straddle
generally  may be deducted  only to the extent the loss  exceeds the  unrealized
gain on the offsetting  position(s) of the straddle.  Section 1092 also provides
certain "wash sale" rules,  which apply to transactions where a position is sold
at a loss and a new offsetting  position is acquired within a prescribed period,
and "short  sale"  rules  applicable  to  straddles.  If the Fund makes  certain
elections,  the amount,  character  and timing of the  recognition  of gains and
losses from the affected straddle positions would be determined under rules that
vary  according to the  elections  made.  Because only a few of the  regulations
implementing the straddle rules have been  promulgated,  the tax consequences to
the Fund of straddle transactions are not entirely clear.

If the Fund has an "appreciated  financial  position" -- generally,  an interest
(including an interest  through an option,  futures or forward contract or short
sale) with respect to any stock, debt instrument (other than "straight debt") or
partnership  interest the fair market value of which exceeds its adjusted  basis
- -- and enters into a "constructive  sale" of the same or  substantially  similar
property,  the Fund will be treated as having made an actual sale thereof,  with
the result  that gain will be  recognized  at that  time.  A  constructive  sale
generally consists of a short sale, an offsetting notional principal contract or
futures or forward  contract  entered into by the Fund or a related  person with
respect to

                                                                              15

<PAGE>

the same or  substantially  similar  property.  In addition,  if the appreciated
financial position is itself a short sale or such a contract, acquisition of the
underlying  property  or  substantially   similar  property  will  be  deemed  a
constructive sale.

The foregoing tax  discussion  is a summary  included for general  informational
purposes only.  Each  shareholder is advised to consult its own tax adviser with
respect to the specific tax  consequences  to it of an  investment  in the Fund,
including the effect and  applicability of state,  local,  foreign and other tax
laws and the possible effects of changes in federal or other tax laws.

Shortly  after the end of each year,  PFPC  calculates  the  federal  income tax
status of all distributions  made during the year. In addition to federal income
tax,  shareholders may be subject to state and local taxes on distributions from
the Fund.  You should  consult  your tax adviser  regarding  specific  questions
relating to federal, state and local taxes.

                     CALCULATION OF PERFORMANCE INFORMATION

The  performance  of the Fund may be  quoted in terms of its yield and its total
return in advertising and other promotional  materials.  Performance data quoted
represents past performance and is not intended to indicate future  performance.
Performance of the Fund will vary based on changes in market  conditions and the
level of the Fund's expenses.  These  performance  figures are calculated in the
following manner:

      A.  AVERAGE  ANNUAL TOTAL RETURN is the average  annual  compound  rate of
return for the periods of one year,  five  years,  ten years and the life of the
Fund, where applicable,  all ended on the last day of a recent calendar quarter.
Average  annual  total  return  quotations  reflect  changes in the price of the
Fund's  shares,  if any,  and assume that all  dividends  during the  respective
periods  were  reinvested  in  Fund  shares.  Average  annual  total  return  is
calculated  by  finding  the  average  annual  compound  rates  of  return  of a
hypothetical  investment over such periods,  according to the following  formula
(average annual total return is then expressed as a percentage):


                               T = (ERV/P)1/n - 1

             Where: P = a hypothetical initial investment of $1,000

                    T = average annual total return

                    n = number of years

                  ERV = ending  redeemable  value:  ERV is
                        the   value,   at  the  end  of  the
                        applicable period, of a hypothetical
                        $1,000   investment   made   at  the
                        beginning of the applicable period.

      B.  YIELD  CALCULATIONS.  From time to time,  the Fund may  advertise  its
yield. Yield for the Fund is calculated by dividing the Fund's investment income
for a 30-day period,  net of expenses,  by the average number of shares entitled
to receive dividends during that period according to the following formula:

                          YIELD = 2[((a-b)/cd + 1)6-1]

                  where:

     a = dividends and interest earned during the period;
     b = expenses accrued for the period (net of reimbursements);
     c = the average daily number of shares outstanding during the
         period that were entitled to receive dividends; and
     d = the maximum offering price per share on the last day of the period.

The  result  is  expressed  as an  annualized  percentage  (assuming  semiannual
compounding) of the maximum offering price per share at the end of the period.

                                                                              16

<PAGE>

Except  as noted  below,  in  determining  interest  earned  during  the  period
(variable "a" in the above formula), pfpc calculates the interest earned on each
debt  instrument  held by the Fund  during  the period  by:  (i)  computing  the
instrument's yield to maturity,  based on the value of the instrument (including
actual  accrued  interest) as of the last  business day of the period or, if the
instrument  was  purchased  during the period,  the purchase  price plus accrued
interest;  (ii) dividing the yield to maturity by 360; and (iii) multiplying the
resulting  quotient by the value of the  instrument  (including  actual  accrued
interest).  Once  interest  earned is  calculated  in this fashion for each debt
instrument  held  by the  Fund,  interest  earned  during  the  period  is  then
determined by totaling the interest earned on all debt  instruments  held by the
Fund.

For purposes of these  calculations,  the maturity of a debt instrument with one
or more call  provisions is assumed to be the next date on which the  instrument
reasonably  can be  expected to be called or, if none,  the  maturity  date.  In
general,  interest income is reduced with respect to debt instruments trading at
a premium  over their par value by  subtracting  a portion of the  premium  from
income on a daily basis, and increased with respect to debt instruments  trading
at a discount by adding a portion of the discount to daily income.

In  determining  dividends  earned  by  any  preferred  stock  or  other  equity
securities  held by the  Fund  during  the  period  (variable  "a" in the  above
formula),  PFPC  accrues the  dividends  daily at their stated  dividend  rates.
Capital gains and losses generally are excluded from yield calculations.

Because yield  accounting  methods  differ from the  accounting  methods used to
calculate net  investment  income for other  purposes,  the Fund's yield may not
equal the dividend  income  actually  paid to  investors  or the net  investment
income reported with respect to the Fund in the Fund's financial statements.

Yield  information  may be useful in  reviewing  the Fund's  performance  and in
providing a basis for comparison with other  investment  alternatives.  However,
the Fund's yields fluctuate,  unlike  investments that pay a fixed interest rate
over a stated  period of time.  Investors  should  recognize  that in periods of
declining interest rates, the Fund's yields will tend to be somewhat higher than
prevailing  market rates,  and in periods of rising interest  rates,  the Fund's
yields will tend to be somewhat  lower.  Also,  when interest rates are falling,
the inflow of net new money to the Fund from the  continuous  sale of its shares
will likely be invested in instruments  producing  lower yields than the balance
of the Funds'  holdings,  thereby  reducing the current  yields of the Fund.  In
periods of rising interest rates, the opposite can be expected to occur.

COMPARISON OF FUND PERFORMANCE.  A comparison of the quoted performance  offered
for various  investments  is valid only if performance is calculated in the same
manner.  Since  there are many  methods of  calculating  performance,  investors
should  consider the effects of the methods used to calculate  performance  when
comparing  performance of the Fund with performance quoted with respect to other
investment companies or types of investments.  For example, it is useful to note
that yields reported on debt instruments are generally  prospective,  contrasted
with the historical yields reported by the Fund.

In connection  with  communicating  its  performance  to current or  prospective
shareholders,  the Fund also may compare  these  figures to the  performance  of
other  mutual  funds  tracked by mutual  fund rating  services  or to  unmanaged
indices which may assume  reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

From time to time, in marketing and other literature, the Fund's performance may
be compared to the  performance  of broad groups of  comparable  mutual funds or
unmanaged  indexes of comparable  securities with similar  investment  goals, as
tracked by independent  organizations  such as Investment Company Data, Inc. (an
organization which provides performance ranking information for broad classes of
mutual  funds),  Lipper  Analytical  Services,  Inc.  ("Lipper")  (a mutual fund
research  firm  which  analyzes  over  1,800  mutual   funds),   CDA  Investment
Technologies,  Inc. (an organization  which provides mutual fund performance and
ranking  information),  Morningstar,  Inc. (an organization  which analyzes over
2,400 mutual funds) and other independent organizations.  When Lipper's tracking
results  are used,  the Fund  will be  compared  to  Lipper's  appropriate  fund
category,  that is, by fund  objective and portfolio  holdings.  Rankings may be
listed among one or more of the asset-size classes as determined by Lipper. When
other organizations' tracking results are used, the Fund will be compared to the
appropriate fund category, that is, by fund objective and portfolio holdings, or
to the  appropriate  volatility  grouping,  where  volatility  is a measure of a
fund's risk.

                                                                              17

<PAGE>

Since the assets in all funds are always changing, the Fund may be ranked within
one asset-size  class at one time and in another  asset-size class at some other
time.  In  addition,  the  independent  organization  chosen to rank the Fund in
marketing and promotional literature may change from time to time depending upon
the basis of the  independent  organization's  categorizations  of mutual funds,
changes in a Fund's investment  policies and investments,  the Fund's asset size
and other factors deemed relevant. Advertisements and other marketing literature
will indicate the time period and Lipper  asset-size class or other  performance
ranking company criteria, as applicable, for the ranking in question.

advertisements  concerning the Fund,  including  reprints of or selections from,

                                   APPENDIX A
            OPTIONS, FUTURES AND FORWARD CURRENCY CONTRACT STRATEGIES

REGULATION  OF  THE  USE OF  OPTIONS,  FUTURES  AND  FORWARD  CURRENCY  CONTRACT
STRATEGIES.  As discussed in the prospectus, in managing the Series, the adviser
may engage in certain options,  futures and forward currency contract strategies
for certain bona fide hedging,  risk  management or other  portfolio  management
purposes.  Certain special  characteristics  of and risks  associated with using
these  strategies  are  discussed  below.  Use of  options,  futures and forward
currency contracts is subject to applicable  regulations and/or  interpretations
of the SEC and the  several  options  and  futures  exchanges  upon which  these
instruments  may be  traded.  The  Board  of  Trustees  has  adopted  investment
guidelines (described below) reflecting these regulations.

In addition to the products,  strategies  and risks  described  below and in the
prospectus,   the  adviser  expects  to  discover  additional  opportunities  in
connection  with  options,  futures and forward  currency  contracts.  These new
opportunities  may become  available as new  techniques  develop,  as regulatory
authorities  broaden the range of  permitted  transactions  and as new  options,
futures and forward currency contracts are developed. These opportunities may be
utilized to the extent they are consistent with the Fund's investment  objective
and  limitations  and  permitted  by  applicable  regulatory  authorities.   The
registration  statement for the Fund will be supplemented to the extent that new
products and strategies involve materially  different risks than those described
below and in the prospectus.

COVER  REQUIREMENTS.  The Series  will not use  leverage  in their  options  and
futures.  Accordingly, the Series will comply with guidelines established by the
SEC with  respect to coverage of these  strategies  by either (1) setting  aside
cash or liquid,  unencumbered,  daily marked-to-market securities in one or more
segregated  accounts with the custodian in the prescribed amount; or (2) holding
securities  or other options or futures  contracts  whose values are expected to
offset ("cover") their obligations thereunder.  Securities, currencies, or other
options or futures  contracts  used for cover cannot be sold or closed out while
these strategies are outstanding,  unless they are replaced with similar assets.
As a result,  there is a  possibility  that the use of cover  involving  a large
percentage  of the Series'  assets could  impede  portfolio  management,  or the
Series' ability to meet redemption requests or other current obligations.

OPTIONS STRATEGIES.  The Series may purchase and write (sell) only those options
on  securities  and  securities  indices  that  are  traded  on U.S.  exchanges.
Exchange-traded  options  in the U.S.  are  issued  by a  clearing  organization
affiliated with the exchange,  on which the option is listed,  which, in effect,
guarantees completion of every exchange-traded option transaction.

The Series may purchase  call options on securities in which it is authorized to
invest in order to fix the cost of a future  purchase.  Call options also may be
used as a means of  enhancing  returns  by,  for  example,  participating  in an
anticipated price increase of a security. In the event of a decline in the price
of the  underlying  security,  use of this  strategy  would  serve to limit  the
potential  loss to the Series to the option  premium  paid;  conversely,  if the
market price of the underlying  security  increases above the exercise price and
the Series either sells or exercises the option, any profit eventually  realized
would be reduced by the premium paid.

The Series may  purchase  put  options on  securities  that it holds in order to
hedge against a decline in the market value of the securities held or to enhance
return. The put option enables the Series to sell the underlying security at the
predetermined  exercise price;  thus, the potential for loss to the Series below
the exercise price is limited to the option premium paid. If the market price of
the underlying security is higher than the exercise price of the put option, any
profit the Series realizes on the sale of the security is reduced by the premium
paid for the put option less any amount for which the put option may be sold.

The Series may on certain occasions wish to hedge against a decline in the
market value of securities that it holds at a time when put options on those
securities are not available for purchase. At those times, the Series Master may
purchase a put option on other carefully selected securities in which it is
authorized to invest, the values of which historically have a high degree of
positive correlation to the value of the securities actually held. If the
adviser's judgment is correct, changes in the value of the put options should
generally offset changes in the value of the securities being hedged. However,
the correlation between the two values may not be as close in these transactions
as in transactions in which the Series purchases a put option on a security that
it

                                      A-1

<PAGE>

holds. If the value of the securities  underlying the put option falls below the
value of the  portfolio  securities,  the put  option may not  provide  complete
protection against a decline in the value of the portfolio securities.

The  Series  may  write  covered  call  options  on  securities  in  which it is
authorized to invest for hedging  purposes or to increase  return in the form of
premiums  received from the  purchasers of the options.  A call option gives the
purchaser of the option the right to buy, and the writer (seller) the obligation
to sell, the underlying security at the exercise price during the option period.
The strategy may be used to provide limited protection against a decrease in the
market price of the  security,  in an amount  equal to the premium  received for
writing the call option less any transaction costs. Thus, if the market price of
the underlying  security held by the Series declines,  the amount of the decline
will be offset  wholly or in part by the amount of the  premium  received by the
Series. If, however,  there is an increase in the market price of the underlying
security and the option is  exercised,  the Series will be obligated to sell the
security at less than its market value.

The Series may also  write  covered  put  options on  securities  in which it is
authorized  to invest.  A put option gives the purchaser of the option the right
to sell, and the writer (seller) the obligation to buy, the underlying  security
at the exercise price during the option period. So long as the obligation of the
writer  continues,  the  writer  may  be  assigned  an  exercise  notice  by the
broker-dealer through whom such option was sold, requiring it to make payment of
the exercise price against delivery of the underlying security. The operation of
put options in other  respects,  including  their related risks and rewards,  is
substantially  identical  to that  of call  options.  If the put  option  is not
exercised, the Series will realize income in the amount of the premium received.
This technique  could be used to enhance current return during periods of market
uncertainty.  The risk in such a  transaction  would be that the market price of
the  underlying  securities  would  decline  below the  exercise  price less the
premiums received, in which case the Series would expect to suffer a loss.

The Series may  purchase  put and call  options  and write  covered put and call
options  on  indexes  in much the same  manner as the more  traditional  options
discussed above,  except that index options may serve as a hedge against overall
fluctuations  in  the  securities  markets  (or a  market  sector)  rather  than
anticipated  increases or decreases  in the value of a particular  security.  An
index assigns values to the securities included in the index and fluctuates with
changes in such values.  Settlements  of index  options are  effected  with cash
payments and do not involve delivery of securities.  Thus, upon settlement of an
index  option,  the purchaser  will realize,  and the writer will pay, an amount
based on the difference  between the exercise price and the closing price of the
index. The  effectiveness of hedging  techniques using index options will depend
on the extent to which price  movements  in the index  selected  correlate  with
price  movements  of  the  securities  in  which  the  Series  invests.  Perfect
correlation is not possible because the securities held or to be acquired by the
Series will not exactly  match the  composition  of indexes on which options are
purchased or written.

The Series may purchase and write covered straddles on securities or indexes.  A
long  straddle  is a  combination  of a call  and a put  purchased  on the  same
security  where  the  exercise  price  of the put is less  than or  equal to the
exercise price on the call. The Series would enter into a long straddle when the
adviser  believes that it is likely that prices will be more volatile during the
term of the options than is implied by the option pricing. A short straddle is a
combination  of a call and a put written on the same security where the exercise
price on the put is less than or equal to the  exercise  price of the call where
the same issue of the  security is  considered  "cover" for both the put and the
call.  The Series would enter into a short  straddle  when the adviser  believes
that it is  unlikely  that  prices  will be as  volatile  during the term of the
options as is implied by the option  pricing.  In such case, the Series will set
aside cash and/or liquid,  unencumbered  securities in a segregated account with
its  custodian  equivalent  in value to the amount,  if any, by which the put is
"in-the-money,"  that is,  that  amount by which the  exercise  price of the put
exceeds the current market value of the underlying  security.  Because straddles
involve multiple trades, they result in higher transaction costs and may be more
difficult to open and close out.

The Series may purchase put and call warrants with values that vary depending on
the change in the value of one or more specified indexes ("index warrants").  An
index warrant is usually  issued by a bank or other  financial  institution  and
gives the Series  the right,  at any time  during  the term of the  warrant,  to
receive  upon  exercise  of the  warrant a cash  payment  from the issuer of the
warrant based on the value of the underlying  index at the time of exercise.  In
general,  if the Series  holds a call  warrant  and the value of the  underlying
index rises above the exercise price of the warrant, the Series will be entitled
to receive a cash payment from the issuer upon exercise  based on the difference
between the value of the index and the  exercise  price of the  warrant;  if the
Series  holds a

                                      A-2

<PAGE>

put warrant and the value of the  underlying  index  falls,  the
Series will be entitled to receive a cash payment from the issuer upon  exercise
based on the difference  between the exercise price of the warrant and the value
of the index.  The Series  holding a call  warrant  would not be entitled to any
payments from the issuer at any time when the exercise price is greater than the
value of the  underlying  index;  the Series  holding a put warrant would not be
entitled to any payments  when the exercise  price is less than the value of the
underlying  index. If the Series does not exercise an index warrant prior to its
expiration,  then the Series loses the amount of the purchase price that it paid
for the warrant.

The Series will  normally use index  warrants as it may use index  options.  The
risks of the  Series'  use of index  warrants  are  generally  similar  to those
relating to its use of index options. Unlike most index options,  however, index
warrants are issued in limited  amounts and are not  obligations  of a regulated
clearing  agency,  but  are  backed  only by the  credit  of the  bank or  other
institution which issues the warrant. Also, index warrants generally have longer
terms than index options. Index warrants are not likely to be as liquid as index
options backed by a recognized clearing agency. In addition,  the terms of index
warrants  may limit the Series'  ability to exercise the warrants at any time or
in any quantity.

OPTIONS  GUIDELINES.  In  view  of the  risks  involved  in  using  the  options
strategies  described  above,  the Series has adopted the  following  investment
guidelines  to  govern  its  use of such  strategies;  these  guidelines  may be
modified by the Board of Trustees without shareholder approval:

      (1) the Series will write only covered options,  and each such option will
          remain covered so long as the Series is obligated thereby; and

      (2) the Series will not write options (whether on securities or securities
          indexes) if aggregate exercise prices of previous written  outstanding
          options,  together  with  the  value  of  assets  used  to  cover  all
          outstanding positions, would exceed 25% of its total net assets.

SPECIAL CHARACTERISTICS AND RISKS OF OPTIONS TRADING. The Series may effectively
terminate  its right or  obligation  under an option by entering  into a closing
transaction.  If the Series  wishes to terminate  its  obligation to purchase or
sell  securities  under a put or a call  option it has  written,  the Series may
purchase a put or a call option of the same series (that is, an option identical
in its  terms to the  option  previously  written).  This is known as a  closing
purchase transaction. Conversely, in order to terminate its right to purchase or
sell  specified  securities  under a call or put  option it has  purchased,  the
Series may sell an option of the same series as the option  held.  This is known
as a closing  sale  transaction.  Closing  transactions  essentially  permit the
Series to realize profits or limit losses on its options  positions prior to the
exercise  or  expiration  of the  option.  If the  Series  is unable to effect a
closing purchase transaction with respect to options it has acquired, the Series
will have to allow the options to expire without  recovering all or a portion of
the option  premiums paid. If the Series is unable to effect a closing  purchase
transaction with respect to covered options it has written,  the Series will not
be able to sell the  underlying  securities  or dispose of assets  used as cover
until the  options  expire  or are  exercised,  and the  Series  may  experience
material  losses  due to  losses on the  option  transaction  itself  and in the
covering securities.

In considering  the use of options to enhance  returns or for hedging  purposes,
particular note should be taken of the following:

      (1) The value of an option position will reflect,  among other things, the
          current  market price of the  underlying  security or index,  the time
          remaining until expiration,  the relationship of the exercise price to
          the market price,  the historical  price  volatility of the underlying
          security or index, and general market conditions. For this reason, the
          successful  use of  options  depends  upon the  adviser's  ability  to
          forecast  the  direction  of  price  fluctuations  in  the  underlying
          securities  markets or, in the case of index options,  fluctuations in
          the market sector represented by the selected index.

      (2) Options  normally  have  expiration  dates  of up to three  years.  An
          American  style put or call option may be exercised at any time during
          the option  period  while a European  style put or call

                                      A-3

<PAGE>

          option may be exercised only upon  expiration or during a fixed period
          prior to  expiration.  The exercise price of the options may be below,
          equal to or above the current market value of the underlying  security
          or index.  Purchased  options that expire  unexercised  have no value.
          Unless an option  purchased  by the  Series is  exercised  or unless a
          closing  transaction  is effected with respect to that  position,  the
          Series will  realize a loss in the amount of the premium  paid and any
          transaction costs.

      (3) A position in an  exchange-listed  option may be closed out only on an
          exchange  that  provides a  secondary  market for  identical  options.
          Although   the  Series   intends  to  purchase  or  write  only  those
          exchange-traded  options  for  which  there  appears  to  be a  liquid
          secondary market, there is no assurance that a liquid secondary market
          will exist for any particular  option at any particular time. A liquid
          market may be absent if: (i) there is insufficient trading interest in
          the option;  (ii) the  exchange has imposed  restrictions  on trading,
          such as trading  halts,  trading  suspensions  or daily price  limits;
          (iii) normal  exchange  operations  have been  disrupted;  or (iv) the
          exchange has inadequate facilities to handle current trading volume.

      (4) With certain  exceptions,  exchange listed options generally settle by
          physical  delivery  of the  underlying  security.  Index  options  are
          settled  exclusively in cash for the net amount,  if any, by which the
          option is "in-the-money" (where the value of the underlying instrument
          exceeds, in the case of a call option, or is less than, in the case of
          a put option, the exercise price of the option) at the time the option
          is  exercised.  If the Series  writes a call  option on an index,  the
          Series will not know in advance the  difference,  if any,  between the
          closing value of the index on the exercise date and the exercise price
          of the call  option  itself  and thus will not know the amount of cash
          payable  upon  settlement.  If the  Series  holds an index  option and
          exercises it before the closing index value for that day is available,
          the Series  runs the risk that the level of the  underlying  index may
          subsequently change.

      (5) The Series'  activities in the options  markets may result in a higher
          Series  turnover rate and additional  brokerage  costs;  however,  the
          Series also may save on commissions by using options as a hedge rather
          than buying or selling individual securities in anticipation of, or as
          a result of, market movements.

FUTURES  AND  RELATED  OPTIONS  STRATEGIES.  The  Series  may  engage in futures
strategies  for certain  non-trading  bona fide  hedging,  risk  management  and
portfolio management purposes.

The Series may sell  securities  index futures  contracts in  anticipation  of a
general market or market sector decline that could  adversely  affect the market
value of the Series'  securities  holdings.  To the extent that a portion of the
Series' holdings  correlate with a given index, the sale of futures contracts on
that index  could  reduce the risks  associated  with a market  decline and thus
provide an alternative to the liquidation of securities positions.  For example,
if the Series  correctly  anticipates a general  market  decline and sells index
futures to hedge  against  this risk,  the gain in the futures  position  should
offset  some or all of the  decline in the value of the  Series'  holdings.  The
Series may purchase  index futures  contracts if a significant  market or market
sector advance is anticipated. Such a purchase of a futures contract would serve
as a temporary substitute for the purchase of the underlying  securities,  which
may then be  purchased,  in an orderly  fashion.  This strategy may minimize the
effect of all or part of an increase in the market price of securities  that the
Series intends to purchase.  A rise in the price of the securities  should be in
part or wholly offset by gains in the futures position.

As in the case of a  purchase  of an index  futures  contract,  the  Series  may
purchase a call option on an index  futures  contract to hedge  against a market
advance in  securities  that the Series plans to acquire at a future  date.  The
Series may write covered put options on index futures as a partial  anticipatory
hedge,  and may write  covered call options on index  futures as a partial hedge
against a  decline  in the  prices of  securities  held by the  Series.  This is
analogous to writing  covered call  options on  securities.  The Series also may
purchase put options on index futures contracts.  The purchase of put options on
index futures  contracts is analogous to the purchase of protective  put options
on  individual  securities  where a level of protection is sought below which no
additional economic loss would be incurred by the Series.

FUTURES AND RELATED OPTIONS  GUIDELINES.  In view of the risks involved in using
the futures  strategies  that are  described  above,  the Series has adopted the
following investment guidelines to govern its use of such strategies.  The Board
of Trustees may modify these guidelines without shareholder vote.

      (1) The Series will engage only in covered futures transactions,  and each
          such  transaction  will  remain  covered  so  long  as the  Series  is
          obligated thereby.

      (2) The Series will not write  options on futures  contracts  if aggregate
          exercise prices of previously written  outstanding options (whether on
          securities or securities  indexes),  together with the value of assets
          used to cover all outstanding  futures positions,  would exceed 25% of
          its total net assets.

SPECIAL  CHARACTERISTICS  AND RISKS OF FUTURES AND RELATED OPTIONS  TRADING.  No
price is paid upon entering into a futures contract. Instead, upon entering into
a futures contract,  the Series is required to deposit with its custodian,  in a
segregated  account  in  the  name  of  the  futures  broker  through  whom  the
transaction is effected,  an amount of cash, U.S. Government securities or other
liquid  instruments  generally equal to 10% or less of the contract value.  This
amount is known as "initial  margin."  When  writing a call or a put option on a
futures  contract,  margin also must be deposited in accordance  with applicable
exchange  rules.  Unlike margin in securities  transactions,  initial  margin on
futures   contracts   does  not  involve   borrowing   to  finance  the  futures
transactions. Rather, initial margin on a futures contract is in the nature of a
performance  bond or good-faith  deposit on the contract that is returned to the
Series upon termination of the  transaction,  assuming all obligations have been
satisfied. Under certain circumstances,  such as periods of high volatility, the
Series  may be  required  by a futures  exchange  to  increase  the level of its
initial  margin  payment.  Additionally,  initial  margin  requirements  may  be
increased  generally in the future by regulatory  action.  Subsequent  payments,
called "variation  margin," to and from the broker, are made on a daily basis as
the value of the futures or options position varies, a process known as "marking
to market." For example,  when the Series  purchases a contract and the value of
the  contract  rises,  the Series  receives  from the broker a variation  margin
payment equal to that increase in value. Conversely, if the value of the futures
position declines,  the Series is required to make a variation margin payment to
the broker  equal to the  decline in value.  Variation  margin  does not involve
borrowing  to finance the futures  transaction,  but rather  represents  a daily
settlement of the Series' obligations to or from a clearing organization.

Buyers and  sellers of futures  positions  and  options  thereon  can enter into
offsetting closing  transactions,  similar to closing transactions on options on
securities,  by selling or purchasing an offsetting contract or option.  Futures
contracts or options thereon may be closed only on an exchange or board of trade
providing a secondary market for such futures contracts or options.

Under certain circumstances, futures exchanges may establish daily limits on the
amount that the price of a futures contract or related option may vary either up
or down from the previous day's settlement  price. Once the daily limit has been
reached  in a  particular  contract,  no trades  may be made that day at a price
beyond  that  limit.  The daily  limit  governs  only price  movements  during a
particular  trading day and therefore does not limit potential  losses,  because
prices could move to the daily limit for several  consecutive  trading days with
little or no trading and  thereby  prevent  prompt  liquidation  of  unfavorable
positions.  In such  event,  it may not be  possible  for the  Series to close a
position and, in the event of adverse price movements,  the Series would have to
make daily cash  payments of variation  margin  (except in the case of purchased
options).  However,  if  futures  contracts  have been  used to hedge  portfolio
securities,  such  securities  will  not be  sold  until  the  contracts  can be
terminated.  In such circumstances,  an increase in the price of the securities,
if any,  may  partially or  completely  offset  losses on the futures  contract.
However,  there is no guarantee that the price of the securities  will, in fact,
correlate  with the price  movements in the contracts and thus provide an offset
to losses on the contracts.

In  considering  the  Series'  use of futures  contracts  and  related  options,
particular note should be taken of the following:

      (1) Successful use by the Series of futures  contracts and related options
          will depend upon the  adviser's  ability to predict  movements  in the
          direction of the securities  markets,  which requires different skills
          and  techniques  than  predicting  changes in the prices of individual
          securities.

                                      A-5
<PAGE>

          Moreover, futures contracts relate not only to the current price level
          of the underlying securities,  but also to anticipated price levels at
          some point in the  future.  There is, in  addition,  the risk that the
          movements in the price of the futures contract will not correlate with
          the  movements  in the  prices of the  securities  being  hedged.  For
          example, if the price of an index futures contract moves less than the
          price of the securities  that are the subject of the hedge,  the hedge
          will not be fully effective,  but if the price of the securities being
          hedged has moved in an unfavorable direction, the Series would be in a
          better  position than if it had not hedged at all. If the price of the
          securities  being  hedged  has  moved in a  favorable  direction,  the
          advantage may be partially  offset by losses in the futures  position.
          In addition,  if the Series has insufficient cash, it may have to sell
          assets to meet daily variation margin  requirements.  Any such sale of
          assets may or may not be made at prices that reflect a rising  market.
          Consequently,  the Series may need to sell  assets at a time when such
          sales are  disadvantageous  to the Series. If the price of the futures
          contract moves more than the price of the underlying  securities,  the
          Series will experience either a loss or a gain on the futures contract
          that may or may not be completely  offset by movements in the price of
          the securities that are the subject of the hedge.

      (2) In  addition  to  the  possibility  that  there  may  be an  imperfect
          correlation,  or no correlation at all, between price movements in the
          futures  position and the  securities  being hedged,  movements in the
          prices of futures contracts may not correlate perfectly with movements
          in the prices of the hedged securities due to price distortions in the
          futures market. There may be several reasons unrelated to the value of
          the underlying  securities that cause this situation to occur.  First,
          as noted above,  all participants in the futures market are subject to
          initial  and  variation  margin  requirements.  If,  to avoid  meeting
          additional margin deposit requirements or for other reasons, investors
          choose to close a  significant  number of  futures  contracts  through
          offsetting transactions,  distortions in the normal price relationship
          between  the  securities  and the futures  markets may occur.  Second,
          because the margin deposit requirements in the futures market are less
          onerous than margin  requirements in the securities market,  there may
          be increased  participation by speculators in the futures market. Such
          speculative  activity in the futures  market also may cause  temporary
          price  distortions.  As a result, a correct forecast of general market
          trends may not result in successful hedging through the use of futures
          contracts  over the  short  term.  In  addition,  activities  of large
          traders in both the futures and securities markets involving arbitrage
          and  other  investment   strategies  may  result  in  temporary  price
          distortions.

      (3) Positions in futures  contracts  may be closed out only on an exchange
          or board of trade that  provides a secondary  market for such  futures
          contracts.  Although  the Series  intends to purchase and 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 at any particular time. In such event, it may not be possible
          to  close a  futures  position,  and in the  event  of  adverse  price
          movements,  the Series would continue to be required to make variation
          margin payments.

      (4) Like options on securities,  options on futures contracts have limited
          life.  The ability to establish  and close out options on futures will
          be subject to the  development  and  maintenance  of liquid  secondary
          markets on the relevant  exchanges or boards of trade. There can be no
          certainty that such markets for all options on futures  contracts will
          develop.

      (5) Purchasers  of options on futures  contracts  pay a premium in cash at
          the time of purchase.  This amount and the  transaction  costs are all
          that is at risk.  Sellers of options  on futures  contracts,  however,
          must post initial  margin and are subject to  additional  margin calls
          that could be substantial in the event of adverse price movements.  In
          addition,  although  the  maximum  amount  at  risk  when  the  Series
          purchases  an  option  is the  premium  paid  for the  option  and the
          transaction  costs, there may be circumstances when the purchase of an
          option on a futures contract would result in a loss to the Series when
          the use of a futures  contract  would  not,  such as when  there is no
          movement in the level of the underlying  index value or the securities
          or currencies being hedged.

                                      A-6

      (6) As is the case with  options,  the Series'  activities  in the futures
          markets may result in a higher portfolio  turnover rate and additional
          transaction costs in the form of added brokerage commissions. However,
          the Series also may save on commissions by using futures  contracts or
          options  thereon as a hedge  rather than buying or selling  individual
          securities in anticipation of, or as a result of, market movements.

                                      A-7

                             DESCRIPTION OF RATINGS

Moody's and S&P are private  services that provide ratings of the credit quality
of debt obligations. A description of the ratings assigned by Moody's and S&P to
the securities in which the Series may invest is discussed below.  These ratings
represent  the  opinions  of these  rating  services  as to the  quality  of the
securities that they undertake to rate. It should be emphasized,  however,  that
ratings are  general  and are not  absolute  standards  of quality.  The adviser
attempts to discern  variations in credit rankings of the rating services and to
anticipate  changes in credit  ranking.  However,  subsequent to purchase by the
Series,  an issue of  securities  may  cease  to be rated or its  rating  may be
reduced below the minimum  rating  required for purchase by the Series.  In that
event, an adviser will consider whether it is in the best interest of the Series
to continue to hold the securities.

MOODY'S RATINGS
- ---------------
CORPORATE AND MUNICIPAL BONDS.
- ------------------------------
Aaa:  Bonds that 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
edged." 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 that 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 that make the
long-term risk appear somewhat larger than the Aaa securities.

A: Bonds that 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 some time in the future.

Baa: Bonds that 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.

CORPORATE AND MUNICIPAL  COMMERCIAL  PAPER. The highest rating for corporate and
municipal commercial paper is "P-1" (Prime-1).  Issuers rated P-1 (or supporting
institutions)  have a superior  ability for repayment of senior  short-term debt
obligations.  P-1  repayment  ability  will  often be  evidenced  by many of the
following characteristics:

(BULLET)  Leading market positions in well-established industries.

(BULLET)  High rates of return on funds employed.

(BULLET)  Conservative  capitalization  structure with moderate reliance on debt
          and ample asset protection.

(BULLET)  Broad margins in earnings coverage of fixed financial charges and high
          internal cash generation.

(BULLET)  Well-established  access to a range of  financial  markets and assured
          sources of alternate liquidity.

MUNICIPAL  NOTES.  The  highest  ratings  for  state  and  municipal  short-term
obligations are "MIG 1," "MIG 2" and "MIG 3" (or "VMIG 1," "VMIG 2" and "VMIG 3"
in the case of an issue having a variable-rate demand feature). Notes rated "MIG
1" or "VMIG 1" are judged to be of the best  quality.  There is  present  strong
protection by established cash flows, superior liquidity support or demonstrated
broadbased access to the market for refinancing. Notes rated "MIG 2" or "VMIG 2"
are of high quality,  with margins of protection  that are ample although not so
large  as in the  preceding  group.  Notes  rated  "MIG  3" or  "VMIG  3" are of
favorable  quality,  with all security  elements  accounted  for but lacking the
undeniable strength of the preceding grades.  Liquidity and cash flow protection
may be narrow,  and  market  access  for  refinancing  is likely to be less well
established.

                                      B-1

S&P RATINGS
- -----------

CORPORATE AND MUNICIPAL BONDS.
- ------------------------------

AAA: Bonds rated AAA are highest grade debt  obligations.  This rating indicates
an extremely strong capacity to pay interest and repay principal.

AA:  Bonds  rated AA have a very  strong  capacity  to pay  interest  and  repay
principal and differ from AAA 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.

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
debt in this category than in higher rated categories.

CORPORATE AND  MUNICIPAL  COMMERCIAL  PAPER.  The "A-1" rating for corporate and
municipal  commercial paper indicates that the degree of safety regarding timely
payment is strong.  Those issues  determined to possess  extremely strong safety
characteristics will be rated "A-1+."

MUNICIPAL  NOTES. The "SP-1" rating reflects a very strong or strong capacity to
pay  principal  and interest.  Those issues  determined to possess  overwhelming
safety  characteristics  will be rated  "SP-1+."  The "SP-2"  rating  reflects a
satisfactory capacity to pay principal and interest.

FITCH RATINGS
- -------------

DESCRIPTION OF FITCH'S HIGHEST STATE AND MUNICIPAL NOTES RATING.
- ----------------------------------------------------------------
AAA - Bonds considered to be investment grade and of the highest credit quality.
The  obligor  has an  exceptionally  strong  ability to pay  interest  and repay
principal, which is unlikely to be affected by reasonably foreseeable events.
AA - Bonds considered to be investment  grade and of very high credit quality.
The  obligor's  ability to pay  interest  and repay  principal  is very  strong,
although not quite as strong as bonds rated AAA.
F-1+ - Issues  assigned this rating are regarded as having the strongest  degree
of assurance for timely payment.
F-1 - Issues  assigned this rating  reflect an assurance of timely  payment only
slightly less in degree than issues rated F-1+.
