The Roxbury Small-Cap Growth Fund (the "Small-Cap Fund") and the Roxbury Micro-Cap Fund (the "Micro-Cap Fund") seek to achieve long-term capital appreciation. ________________________________________________________________________________ Investment Focus Equity (or related) securities ________________________________________________________________________________ Share Price Volatility High ________________________________________________________________________________ Principal Investment The Mid-Cap Fund invests, under normal Strategies market conditions, at least 80% of its assets in securities of companies with market capitalizations, at the time of purchase, consistent with the capitalization ranges of the Russell MidCap and S&P MidCap 400 Indices. The Small-Cap Fund invests, under normal market conditions, at least 80% of its assets in securities of companies with market capitalizations, at the time of purchase, consistent with the capitalization ranges of the Russell 2000 and S&P SmallCap 600 Indices. The Micro-Cap Fund invests, under normal conditions, at least 80% of its assets in securities of companies with market capitalizations, at the time of purchase, under $1 billion. The Funds may invest in securities (including preferred stock, warrants and debentures) convertible into or exercisable for common stock and certain option and financial futures contracts ("derivatives"). The Funds may also invest in foreign securities, including American Depositary Receipts. ________________________________________________________________________________ Principal Risks An investment in a Fund is subject to the risks summarized below, which are further described under "Additional Risk Information." o It is possible to lose money by investing in the Funds. There is no guarantee that the stock market or the securities that a Fund ________________________________________________________________________________ - 3 - ________________________________________________________________________________ buys will increase in value. o The Funds' share prices will fluctuate in response to changes in market value of the Funds' underlying investments. Market value changes result from business developments affecting an issuer as well as general market and economic conditions. o The Funds are subject to greater volatility than funds that invest in large cap companies. Mid-cap, small-cap and micro-cap companies may be more vulnerable than large-cap companies to adverse business or economic developments, their securities may be less liquid and more volatile than securities of larger companies, may suffer significant losses. o Growth-oriented investments may be more volatile than the rest of the U.S. stock market as a whole. o Investments in a foreign market are subject to foreign security risk and the risk of losses caused by changes in foreign currency exchange rates. o The use of derivatives may expose a Fund to additional risks that it would not be subject to if it invested directly in securities underlying those derivatives. These risks may cause a Fund to experience higher losses than a fund that does not use derivatives. o The performance of the Funds will depend on whether or not the investment adviser is successful in pursuing the Funds' investment strategies. o The Funds are also subject to other risks which are described under "Additional Risk Information." ________________________________________________________________________________ Investor Profile Investors who want the value of their investment to grow and who are willing to accept more volatility for the possibility of higher returns. ________________________________________________________________________________ - 4 - ________________________________________________________________________________ PERFORMANCE INFORMATION ________________________________________________________________________________ Roxbury Mid-Cap Fund The bar chart and performance table below illustrate the risks and volatility of an investment in the Fund by showing changes in the performance of the Fund's Investor Shares (formerly, Class A Shares) from calendar year to calendar year and by showing how the Fund's average annual returns for one year and since inception, both before and after taxes, compared with those of the Russell MidCap Growth Index, which is a broad measure of market performance. The Fund's past performance, both before and after taxes, does not necessarily indicate how the Fund will perform in the future.

The example below shows what you would pay if you invested $10,000 over the various time periods indicated. The example assumes that: o you reinvested all dividends and other distributions; o the average annual return was 5%; o a Fund's total operating expenses (reflecting contractual waivers and reimbursements) are charged and remain the same over the time periods; and o you redeemed all of your investment at the end of each time period. Although your actual cost may be higher or lower, based on these assumptions, your costs would be: Investor Shares 1 Year 3 Years 5 Years 10 Years __________________ ________ _________ _________ __________ Mid-Cap Fund $158 $490 $845 $1,845 Small-Cap Fund $163 $507 $875 $1,910 Micro-Cap Fund $253 $779 $1,331 $2,836 The above example is for comparison purposes only and is not a representation of a Fund's actual expenses and returns, either past or future. - 8 - ________________________________________________________________________________ INVESTMENT OBJECTIVE ________________________________________________________________________________ The Roxbury Mid-Cap Fund seeks superior long-term growth of capital. Each of the Roxbury Small-Cap Growth Fund and the Roxbury Micro-Cap Fund seeks to achieve long-term capital appreciation. The investment objective of the Mid-Cap Fund and Small-Cap Fund may not be changed without shareholder approval. The investment objective of the Micro-Cap Fund may be changed without shareholder approval upon sixty (60) days written notice to shareholders. There is no guarantee that any Fund will achieve its investment objective. ________________________________________________________________________________ PRIMARY INVESTMENT STRATEGIES ________________________________________________________________________________ The Roxbury Mid-Cap Fund, under normal market conditions, invests at least 80% of its assets in the following equity (or equity-related securities): o common stocks of corporations that are judged by the investment adviser to have strong growth characteristics and, with respect to at least 80% of the Fund's assets, at the time of purchase, have a market capitalization consistent with the capitalization ranges of the Russell Midcap and S&P MidCap 400 Indices ("mid-cap company") o securities convertible into mid-cap companies o options on common stock or stock indices The Fund invests in high quality, growing companies trading at reasonable valuations. It looks for seasoned businesses that can continue to grow in a variety of environments, experienced management teams, and emerging new leaders in technology and other industries. Such companies generally have favorable competitive positions, strong financials, and a commitment to enhancing shareholder value. Other common characteristics of the Fund's portfolio holdings include: effective management teams, proprietary technologies, free cash flow generation, low cost production, and high barriers to entry. The investment process is designed to produce a portfolio of relatively predictable companies with above-average and sustainable growth rates, strong financial strength, high returns of equity and favorable valuation metrics. All holdings are monitored closely. Holdings may be sold when companies become overvalued, more attractive investments are identified, poor relative performance persists, and/or the fundamentals have weakened. Mid-cap companies are those whose capitalization is consistent with the capitalization range of the Russell Midcap and S&P MidCap 400 Indices at the time of a Fund's - 9 - investment. As of September 30, 2005 the range of market capitalization of companies that are in the Russell Midcap and S&P 400 Indices ("Indices") was between $259 million and $17.88 billion. As market conditions change, so will the capitalizations of the companies that make up the Indices. The investment adviser looks for quality, sustainable growth stocks within the mid-cap portion of the market. At the time of initial purchase, an investment's market capitalization will fall within the capitalization range of the Indices. Due to market price adjustments or other events after the time of purchase, it is possible that an investment's market capitalization may drift above or below this range. Nevertheless, companies whose capitalization no longer meets this definition after purchase continue to be considered to have a mid-cap market capitalization for purposes of the 80% policy. The Fund is not limited to only mid-cap companies, and under normal market conditions, may invest up to 20% of its assets in stocks of companies within larger or smaller capitalizations. The Roxbury Small-Cap Growth Fund, under normal market conditions, invests at least 80% of its assets in the following equity (or equity-related securities): o common stocks of U.S. corporations that are judged by the investment adviser to have strong growth characteristics or to be undervalued in the marketplace relative to underlying profitability and have a market capitalization which, at the time of purchase, is consistent with the capitalization ranges of the S&P SmallCap 600 and Russell 2000 Indices ("small-cap companies") o options on, or securities convertible (such as convertible preferred stock, convertible bonds, warrants and debentures ) into, the common stock of small-cap companies o options on indices of the common stock of small-cap companies o contracts for either the future delivery, or payment in respect of the future market value, of certain indices of common stock of small-cap companies, and options upon such futures contracts The research process for this Fund begins by screening a universe of stocks with market capitalizations of less than $2 billion and expected future earnings growth of greater than 15%. The managers then perform fundamental analysis to identify companies with the following characteristics: growing revenues, stable or expanding margins, low debt levels, solid cash flows, and high or potentially high returns on capital. Additional research is applied to the most promising candidates to uncover those companies with solid management that has executed well over time, strengthening competitive positions, and positive business and market trends. A valuation analysis is then performed to see whether the stock is attractively priced relative to its industry, historical range, and the overall market. A stock becomes a purchase candidate only if the portfolio managers are convinced there is a catalyst in place to provide for at least 15% stock price appreciation over the next 12 months. - 10 - The Fund maintains a portfolio of approximately 60-90 stocks, which is constructed with the overall goal of mitigating risk. Stock positions are limited to a maximum 5% weighting and sector concentrations are +/- 15% of the sector weightings of the benchmark index (Russell 2000 Growth Index). Stocks are sold for undervaluation, when the fundamentals weaken or if poor relative price performance persists. Small-cap companies are those whose capitalizations are consistent with the market capitalizations of companies in the S&P SmallCap 600 and Russell 2000 Indices at the time of a Fund's investment. As of September 30, 2005, the range of market capitalizations represented by companies in the these indices was between $40 million and $6.02 billion. Due to market price adjustments or other events after the time of purchase, it is possible that an investment's market capitalization may drift above or below this range. Nevertheless, a company whose capitalization no longer meets this definition after purchase continues to be considered to have a small market capitalization for purposes of the 80% policy. The Fund is not limited to only small-cap companies and under normal market conditions may invest up to 20% of its assets in stocks of companies in other capitalization ranges. The Roxbury Micro-Cap Fund, under normal market conditions, will invest at least 80% of its assets in the following equity (or equity-related securities): o common stocks of companies that have a market capitalization which, at the time of purchase, is under $1 billion ("micro-cap companies") o options on, or securities convertible (such as convertible preferred stock, convertible bonds, warrants and debentures) into, the common stock of micro-cap companies o options on indices of the common stock of micro-cap companies o contracts for either the future delivery, or payment in respect of the future market value, of certain indices of the common stock of micro-cap companies, and options upon such futures contracts There are typically two types of companies that populate the micro-cap space. The first are new, young businesses in dynamic industries that have developed a new product or are leading a new industry from which there is the expectation for significant growth over a multi-year period. Second are special situations, which are usually more established companies that have faced difficulties in the past for which the Fund's manager has identified a catalyst that may lead to a restructuring. While the majority of the Fund is invested in the former category, approximately 20-25% is placed in these fallen angels, which often offer unique opportunities. Research ideas are generated through a variety of channels, including industry and analyst contacts, trade publications, past experience through years of managing money in this - 11 - space, and being alert to trends in our world. The ideas are then combined with an assessment of the business through scrutinizing the company's balance sheet strength, financial ratios, and trends. A stock becomes a purchase candidate only if the Fund's manager believes it has the potential to appreciate by at least 50% over the next 24 months. Company management, competition, and the industry is then further evaluated to make a final decision. The micro-cap market, by definition, is highly inefficient. The Fund attempts to take advantage of this by buying stocks that others have abandoned or that have otherwise gone unnoticed. Stocks are sold if they become overvalued, if the fundamentals of the business deteriorate, or if a better investment opportunity emerges. Positions are also trimmed if the size or sector weighting grows beyond acceptable limits. Micro-cap companies are those whose capitalization is under $1 billion at the time of the Fund's investment. Due to market price adjustments or other events after the time of purchase, it is possible that an investment's market capitalization may drift above or below this range. Nevertheless, a company whose capitalization no longer meets this definition after purchase continues to be considered to have a micro market capitalization for purposes of the 80% policy. The Fund is not limited to only micro-cap companies and, under normal market conditions, may invest up to 20% of its assets in stocks of companies in higher capitalization ranges. The 80% policy of each Fund may be changed upon sixty (60) days written notice to shareholders. All Funds. The investment adviser selects securities that it believes exhibit strong growth characteristics. The investment adviser uses a bottom up approach to identify new investment opportunities and to evaluate existing investments on an ongoing basis to determine continued suitability. All investments undergo a valuation analysis to estimate their risk/reward characteristics. The Funds may also invest in certain option and financial futures contracts ("derivatives") as well as foreign securities, including American Depositary Receipts ("ADRs"). ADRs are negotiable certificates held in a U.S. bank representing a specific number of shares of a foreign stock traded on a U.S. stock exchange. ADRs make it easier for U.S. citizens to invest in foreign companies, due to the widespread availability of dollar-denominated price information, lower transaction costs, and timely dividend distributions. An American Depositary Share or ADS is the share issued under an American Depositary Receipt agreement which is actually traded. At the time of purchase, individual stock holding may represent up to 5% of a Fund's value. However, due to market price fluctuations, individual stock holdings may exceed 5% of a Fund's value. The Funds may over or underweight certain industries and sectors based on the investment adviser's opinion of the relative attractiveness of companies within those - 12 - industries and sectors. The Funds may not invest in more than 10% of the outstanding voting shares of a company. In order to respond to adverse market, economic, political or other conditions, the Funds may assume a temporary defensive position and invest without limit in commercial paper and other money market instruments that are rated investment grade by a nationally recognized statistical rating organization, or determined by the investment adviser to be of comparable quality. The result of this action may be that a Fund will be unable to achieve its investment objective. The frequency of fund transactions and a Fund's turnover rate will vary from year to year depending on the market. A higher turnover rate increases transaction costs (i.e., brokerage commissions) and adverse tax consequences for a Fund's shareholders. With frequent trading activity, a greater proportion of any dividends paid out by a Fund will be characterized as ordinary income, which is taxed at higher rates than long-term capital gains. Such factors may have the effect of lowering overall fund performance. The Funds also may use other strategies and engage in other investment practices, which are more fully described in the Funds' Statement of Additional Information ("SAI"). ________________________________________________________________________________ ADDITIONAL RISK INFORMATION ________________________________________________________________________________ The following is a list of certain risks that may apply to your investment in a Fund. Further information about investment risks is available in the Funds' SAI. o Small Company Risk: Companies in which the Funds invest may be more vulnerable than larger companies to adverse business or economic developments. Micro-cap, small-cap and mid-cap companies may also have limited product lines, markets or financial resources, may be dependent on relatively small or inexperienced management groups and may operate in industries characterized by rapid technological obsolescence. Securities of such companies may be less liquid and more volatile than securities of larger companies and therefore may involve greater risk than investing in larger companies. o Micro-Cap Risk: Investments by the Micro-Cap Fund in small, new or unseasoned companies which may be in their early stages of development, or small companies positioned in new and emerging industries where the opportunity for rapid growth is expected to be above average are subject to additional risks. Micro-cap companies may have relatively small revenues, limited or very focused product lines, and small shares of the market for their products or services or very large shares of an emerging market. These companies may lack depth of management, they may be unable to internally generate the funds necessary for growth or potential development or to generate such funds through external financing on favorable terms, or they may be developing or marketing new products or - 13 - services for which markets are not yet established and may never become well established. Due to these and other factors, such companies may suffer significant losses and investments in such companies will be volatile and are therefore speculative. Historically, micro-cap stocks have been more volatile in price than larger capitalization stocks. Among the reasons for the greater price volatility of these securities are the lower degree of liquidity in the markets for such stocks, and the potentially greater sensitivity of such small companies to changes in or failure of management and in many other changes in competitive, business, industry and economic conditions, including risks associated with limited product lines, markets, management depth, or financial resources. Besides exhibiting greater volatility, micro-cap and small-cap stocks may, to a degree, fluctuate independently of larger company stocks. Micro-cap and small-cap stocks may decline in price as large company stocks rise, or rise in price as large company stocks decline. Investors should therefore expect that the price of the Micro-Cap Fund's shares will be more volatile than the shares of a fund that invests in larger capitalization stocks. o Growth Investing Risk: The risk that an investment in a growth-oriented fund may be more volatile than the rest of the U.S. market as a whole. o Derivatives Risk: Some of a Fund's investments may be referred to as "derivatives" because their value depends on, or is derived from, the value of an underlying asset, reference rate or index. These investments include options, futures contracts and similar investments that may be used in hedging, risk management, or other fund management purposes consistent with a Fund's investment objective. 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 a Fund's total assets may at any time be committed or exposed to derivative strategies. o Foreign Security Risk: Foreign investments involve risks relating to political, economic, regulatory or social instability, military action or unrest, or diplomatic developments and may be affected by actions of foreign governments adverse to the interest of U.S. investors. o Currency Risk: The risk related to investments denominated in foreign currencies. Foreign securities are usually denominated in foreign currency; therefore, changes in foreign currency exchange rates affect the net asset value of the Funds. o IPO Risk: The Funds may purchase securities of companies engaged in their initial public offerings ("IPOs"). The price of securities purchased in IPOs can be very volatile. The effect of IPO investments on a Fund's performance depends on a variety of factors, including the number of IPOs - 14 - a Fund invests in relative to the size of a Fund, and whether and to what extent a security purchased in an IPO appreciates or depreciates in value. As a Fund's asset base increases, IPOs often have a diminished effect on fund performance. o Liquidity Risk: The risk that certain securities may be difficult or impossible to sell at the time and the price that the seller would like. While the markets in securities of small companies have grown rapidly in recent years, such securities may trade less frequently and in smaller volumes than more widely held securities. The values of these securities may fluctuate more sharply than those of other securities, and a Fund may experience some difficulty in establishing or closing out positions in these securities at prevailing market prices. There may be less publicly available information about the issuers of these securities or less market interest in such securities than in the case of larger companies, and it may take a longer period of time for the prices of such securities to reflect the full value of their issuers' underlying earnings potential or assets. Forced liquidations of a Fund could result in adverse price fluctuations in securities held and in a Fund's overall value. o Market Risk: The risk that the market value of a security may fluctuate, 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. o Valuation Risk: The risk that a Fund has valued certain of its securities at a higher price than it can sell them. - 15 - ________________________________________________________________________________ FINANCIAL HIGHLIGHTS ________________________________________________________________________________ The financial highlights table is intended to help you understand a Fund's financial performance since its inception.

For the periods for which performance information is provided, no other person played a significant role in managing the Composite. At December 31, 2004, the Composite consisted of 18 accounts and $3.14 million in assets. The results presented are not intended to predict or suggest the return to be experienced by the Micro-Cap Fund or the return you might achieve by investing in that Fund. You should not rely on the following performance data as an indication of future performance of the adviser or of the Micro-Cap Fund. Among other reasons, the Micro-Cap Fund's results may be different because of differences in fees and expenses, and the accounts in the Composite are not subject to the same type of expenses to which the Micro-Cap Fund is subject, nor to the diversification requirements, specific tax restrictions and investment limitations imposed on the Micro-Cap Fund by the Investment Company Act of 1940, or the Internal Revenue Code of 1986. The performance of the accounts in the Composite may have been adversely affected had they been subject to the same expenses, restrictions and limitations.

The results shown above (1) represent a composite of all discretionary, fee paying, separate accounts managed using the micro-cap strategy for at least one month, (2) reflect the reinvestment of any dividends or capital gains, and (3) are shown after the deduction of advisory, brokerage or other expenses (excluding fees such as custody fees which are paid separately by the investor). 2. All returns are based in U.S. dollars and are computed using a time-weighted total rate of return. 3. If the Micro-Cap Fund's expenses were reflected in the performance of the Composite, such performance would be lower than shown. The composite's results were calculated in accordance with the CFA Institute (formerly the Association for Investment Management and Research ("AIMR")) mutual fund performance calculation methodology but not in accordance with SEC-mandated mutual fund performance calculation methodology. The CFA Institute has not been involved in the preparation or review of this information. - 20 - Results may have been different if the SEC methodology had been used instead of the AIMR methodology. Past performance is not an indication of future results. 4. The Russell 2000 Index is a passive index that includes the smallest 2,000 stocks in the Russell 3000 Index as measured by market capitalization, to determine their growth or value characteristics. The Russell 2000 Growth Index is formed by assigning a style composite score to all of the companies in the Russell 2000 Index. The indices reflect the reinvestment of dividends but do not reflect fee, brokerage commissions or other expenses of investing. You cannot invest in an index. - 21 - ________________________________________________________________________________ SERVICE PROVIDERS ________________________________________________________________________________ The chart below provides information on the primary service providers. Asset management Investment Adviser Roxbury Capital Management LLC 100 Wilshire Boulevard, Suite 1000 Santa Monica, CA 90401 Manages the Funds' business and investment activities. Fund Operations Administrator and Accounting Agent PFPC Inc. 301 Bellevue Parkway Wilmington, DE 19809 Provides facilities, equipment and personnel to carry out administrative services related to the Funds and calculates the Funds' NAV and distributions. WT MUTUAL FUND Roxbury Mid-Cap Fund Roxbury Small-Cap Growth Fund Roxbury Micro-Cap Fund Distribution Distributor Professional Funds Distributor, LLC 760 Moore Road King of Prussia, PA 19406 Distributes the Funds' shares. Shareholder Services Transfer Agent PFPC Inc. 760 Moore Road King of Prussia, PA 19406 Handles shareholder services, including recordkeeping and statements, payment of distribution and processing of buy and sell requests. Asset Safe Keeping Custodian Wilmington Trust Company 1100 North Market Street Wilmington, DE 19890 Holds the Fund's assets, settles all Fund trades and collects most of the valuation data required for calculating the Funds' NAV per share - 22 - SHAREHOLDER INFORMATION ________________________________________________________________________________ PRICING OF SHARES ________________________________________________________________________________ The price of each Fund's shares is based on its net asset value ("NAV"). Each Fund values its assets based on current market values when such values are available. These prices normally are supplied by an independent pricing service. Any assets held by a 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 Inc. ("PFPC") determines the daily NAV per share. 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 using procedures adopted by the Board of Trustees. When a Fund uses fair value pricing to determine NAV, securities will not be priced on the basis of quotations from the primary market in which they are traded, but rather may be priced by another method that the Board of Trustees believes accurately reflects fair value. The Funds' policy is intended to result in a calculation of a Fund's NAV that fairly reflects security values as of the time of pricing. However, fair values determined pursuant to the Funds' procedures may not accurately reflect the price that a Fund could obtain for a security if it were to dispose of that security as of the time of pricing. PFPC determines the NAV per share of the Funds as of the close of regular trading on the New York Stock Exchange ("Exchange") (currently 4:00 p.m. Eastern time) on each day that the Exchange and the transfer agent are open for business (each, a "Business Day"). The NAV is calculated by adding the value of all securities and other assets in a Fund, deducting its liabilities and dividing the balance by the number of outstanding shares in a Fund. The price at which a purchase, redemption or exchange is effected is based on the next calculation of NAV after the order is received by an authorized financial institution or the transfer agent and, under no circumstances will any order be accepted for purchase, redemption or exchange after the NAV calculation. Shares will only be priced on business days. In addition, foreign securities held by a Fund may trade on weekends or other days when the Fund does not calculate NAV. As a result, the market value of these investments may change on days when shares of the Funds cannot be bought or sold. ________________________________________________________________________________ PURCHASE OF SHARES ________________________________________________________________________________ Fund shares are offered on a continuous basis and are sold without any sales charges. The minimum initial investment in the Funds' Investor Shares is $2,000. Additional investments may be made in any amount. You may purchase shares as specified below. Investors may purchase shares of a Fund through financial intermediaries such as financial consultants, securities brokers, dealers or benefit plan administrators. Investors should contact their financial intermediary directly for appropriate instructions, as well as for - 23 - information pertaining to account and any servicing or transaction fees that may be charged. Some financial intermediaries may appoint subagents. The Funds reserve the right to change the criteria for eligible investors and investment minimums. By Mail: You may purchase shares by sending a check drawn on a U.S. bank payable to Roxbury Funds, indicating the name and class of the Fund, along with a completed application (included at the end of this prospectus). If a subsequent investment is being made, the check should also indicate your Fund account number. When you make purchases by check, the Funds 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: Regular mail: Overnight mail: _____________ _______________ Roxbury Funds Roxbury Funds c/o PFPC Inc. c/o PFPC Inc. P.O. Box 9828 101 Sabin Street Providence, RI 02940 Pawtucket, RI 02860-1427 By Wire: You may purchase shares by wiring federal funds readily available. Please call PFPC at (800) 497-2960 for instructions and to make specific arrangements before making a purchase by wire, and if making an initial purchase, to also obtain an account number. Additional Information Regarding Purchases: Purchase orders received by the transfer agent before the close of regular trading on the Exchange on any Business Day will be priced at the NAV 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 a Fund determines that accepting the order would not be in the best interest of the Fund or its shareholders. 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. For information on other ways to purchase shares, including through an individual retirement account (IRA), an Automatic Investment Plan or a Payroll Investment Plan, please refer to the Funds' SAI. ________________________________________________________________________________ REDEMPTION OF SHARES ________________________________________________________________________________ You may sell (redeem) your shares on any Business Day. Redemptions are effected at the NAV next determined after the transfer agent has received your redemption - 24 - request. If held for more than 60 days, there is no fee when Fund shares are redeemed. If shares are redeemed within 60 days of purchase, a redemption fee of 1.00% for the Mid-Cap and Small-Cap Funds and 2.00% for the Micro-Cap Fund on the redemption amount may be charged. (See "Redemption Fee" below.) It is the responsibility of the financial intermediary to transmit redemption orders and credit their customers' accounts 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. If you purchased your shares through a financial intermediary you should contact the financial intermediary for information relating to redemptions. The Fund's name and your account number should accompany any redemption requests. Redemption Fees: A redemption fee of 1.00% in the case of the Mid-Cap and Small-Cap Funds and 2.00% in the case of the Micro-Cap Fund of the total redemption amount (calculated at market value) may be imposed if you sell your shares within 60 days (the "Holding Period") of your purchase of such shares. This fee will apply to redemptions processed for the purpose of receiving redemption proceeds or processing an exchange between the Roxbury Funds (a list of which is shown under the heading "EXCHANGE OF SHARES" below). This fee is paid directly to the respective Fund and is designed to offset brokerage commissions, market impact and other costs associated with short-term trading. For purposes of determining whether this fee applies, the shares that you have held the longest will be redeemed or exchanged first, however, shares purchased through the reinvestment of dividends or capital gain distributions or shares purchased with retirement plan contributions (e.g., payroll contributions) will not be matched with redemptions or exchanges for purposes of calculating the Holding Period. This fee will not apply in certain circumstances, including (i) shares redeemed (A) via a systematic withdrawal plan approved by the adviser, (B) through an automatic, nondiscretionary rebalancing or asset reallocation program approved by the adviser, (C) as part of a retirement plan participant-directed distribution, including but not limited to, death distributions, hardship withdrawals, loan withdrawals and qualified domestic relations orders, (D) as part of a retirement plan termination or restructuring, (E) to effect a transfer from one retirement plan to another retirement plan in the same Fund, or (F) by a Fund to cover various fees; or (ii) shares converted from one share class to another in the same Fund. See "EXCHANGE OF SHARES" for additional information regarding the exchange of shares of a Roxbury Fund. Frequent Purchases and Redemptions: The Funds are intended to be long-term investment vehicles and are not designed to provide investors with a means of speculating on short-term market movements (market timing). Frequent purchases and redemptions of Fund shares can disrupt the management of a Fund, negatively affect a Fund's performance, and increase expenses for all of a Fund's shareholders. In particular, frequent trading can: (i) force a Fund's portfolio managers to hold larger cash positions than desired instead of fully investing the Fund, which can result in lost investment opportunities; (ii) cause unplanned and inopportune portfolio turnover in order to meet redemption requests; (iii) increase broker-dealer commissions and other transaction costs as well as administrative costs for a Fund; and (iv) trigger taxable gains for other shareholders. Also, some frequent traders engage in arbitrage strategies, by - 25 - which these traders seek to exploit pricing anomalies that can occur when a Fund invests in securities that are thinly traded (for example some small capitalization stocks) or are traded primarily in markets outside of the United States. Frequent traders using arbitrage strategies can dilute a Fund's NAV for long-term shareholders. If you intend to trade frequently or use market timing investment strategies, you should not purchase shares of the Funds. The Board of Trustees has adopted policies and procedures with respect to frequent purchases and redemptions of Fund shares. The Funds' policy is intended to discourage excessive trading in a Fund's shares that may harm long-term investors and to make reasonable efforts to detect and deter excessive trading. The Funds reserve the right to reject any purchase order or exchange request at any time and for any reason, without prior written notice. The Funds may, in certain circumstances, reverse a transaction determined to be abusive. The Funds will generally monitor trading activity within a 90-day period. The Funds may consider trading activity over a longer period than 90 days and may take into account market conditions, the number of trades and the amount of the trades in making such determinations. In applying these policies, the Funds consider the information available to it at the time and may consider trading activity in multiple accounts under common ownership, control or influence. When excessive or short-term trading is detected, the party involved may be banned from future trading in a Fund. Judgments related to the rejection of purchase and the banning of future trades are inherently subjective and involve some selectivity in their application. Roxbury will seek to make judgments and applications that are consistent with the interests of the affected Fund's shareholders. The Funds' policies for deterring excessive trading in Fund shares are intended to be applied uniformly to all Fund shareholders to the extent practicable. Some intermediaries, however, maintain omnibus accounts in which they aggregate orders of multiple investors and forward the aggregated orders to the Fund. Because the Funds receive these orders on an aggregated basis and because these omnibus accounts may trade with numerous fund families with differing market timing policies, a Fund is substantially limited in its ability to identify or deter excessive traders or other abusive traders. The transfer agent for the Funds will use its best efforts to obtain the cooperation of intermediaries to identify excessive traders and to prevent or limit abusive trading activity, to the extent practicable. Nonetheless, a Fund's ability to identify and deter frequent purchases and redemptions of a Fund's shares through omnibus accounts is limited, and a Fund's success in accomplishing the objectives of the policies concerning excessive trading in Fund shares in this context depends significantly upon the cooperation of the intermediaries, which may have adopted their own policies regarding excessive trading which are different than those of the Funds. 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 - 26 - a notary public. You must indicate the Fund name and class, your account number and your name. The written instructions and signature guarantee should be mailed to: Regular mail: Overnight mail: _____________ _______________ Roxbury Funds Roxbury Funds c/o PFPC Inc. c/o PFPC Inc. P.O. Box 9828 101 Sabin Street Providence, RI 02940 Pawtucket, RI 02860-1427 By Telephone: If you prefer to redeem your shares by telephone you may elect to do so. However there are risks. The Funds have 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. Additional Information Regarding Redemptions: 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. For amounts exceeding $10,000, proceeds may be mailed to your bank. In order to authorize the transfer agent to mail redemption proceeds to your account address of record, complete the appropriate section of the Application for Telephone Redemptions or include your 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 signature guarantee. 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. If shares to be redeemed represent a recent investment made by check, the Funds reserve the right to withhold the redemption proceeds available until it believes that the check has been collected (which could take up to 10 days). Small Accounts: If the value of your account falls below the investment minimum, the Funds may ask you to increase your balance. If the account value is still below the investment minimum after 60 days, the Funds may close your account and send you the proceeds. The Funds will not close your account if it falls below the investment minimum solely as a result of a reduction in your account's market value. For additional information on other ways to redeem shares, please refer to the Fund's SAI. ________________________________________________________________________________ EXCHANGE OF SHARES ________________________________________________________________________________ You may exchange all or a portion of your shares in a Fund for Investor Shares of the following funds ("Roxbury Funds"): - 27- Roxbury Mid-Cap Fund Roxbury Small-Cap Growth Fund Roxbury Micro-Cap Fund Redemption of shares through an exchange will be effected at the NAV per share next determined after the transfer agent receives your request. A purchase of shares through an exchange will be effected at the NAV determined at that time or as next determined thereafter. See "Taxes" for a discussion of the tax effect on an exchange of shares. Exchange transactions will be subject to the minimum initial investment and other requirements of a Fund into which the exchange is made. An exchange may not be made if the exchange would leave a balance in a shareholder's account of less than $2,000. Fees on Exchanges: If held for more than 60 days, there is no fee when Fund shares are redeemed to process an exchange for your account. If shares are redeemed within 60 days of purchase, a redemption fee of 1.00% for the Mid-Cap and Small-Cap Funds and 2.00% for the Micro-Cap Fund on the redemption amount necessary for the exchange may be charged. See "Redemption of Shares" for additional information regarding redemptions and this fee. To obtain prospectuses of the Roxbury Funds, you may call (800) 497-2960. To obtain more information about exchanges, or to place exchange orders, contact the transfer agent, or, if your shares are held in an account with a financial intermediary, contact the financial intermediary. The Funds may terminate or modify the exchange offer described here and will give you 60 days' notice of such termination or modification. This exchange offer is valid only in those jurisdictions where the sale of the Fund's shares to be acquired through such exchange may be legally made. ________________________________________________________________________________ DISTRIBUTIONS ________________________________________________________________________________ Distributions from the net investment income, if any, of a Fund are declared and paid annually to you. Any net capital gain realized by a Fund will be distributed annually. Distributions are payable to the shareholders of record at the time the distributions are declared (including holders of shares being redeemed, but excluding holders of shares being purchased). All distributions are reinvested in additional shares, unless you elect to receive the distributions in cash. Shares become entitled to receive distributions on the day after the shares are issued. ________________________________________________________________________________ TAXES ________________________________________________________________________________ As long as a 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 Funds may invest in securities that earn interest exempt from Federal income tax, the Funds invests primarily in taxable securities. The Funds' distributions of net investment income and net short-term capital gains, if any, whether received in cash or reinvested in additional Fund - 28 - shares, are generally taxable to you as ordinary income. If a Fund has dividend income that qualifies as qualified dividend income, as provided in the Jobs and Growth Tax Relief Reconciliation Act of 2003, the maximum amount allowable will be designated by the Fund and such amount will be taxable to individual shareholders at a stated maximum rate of 15%. The Funds will notify you following the end of the calendar year of the amount of dividends and other distributions paid that year. A Fund's distribution of a net capital gain, if any, 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 net 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 Funds anticipate the distribution of net capital gains. It is a taxable event for you if you sell or exchange Fund shares. 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 adviser 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 a Fund. Any discussion of tax matters contained in this prospectus is not intended or written to be used, and cannot be used, for the purpose of avoiding any penalties that may be imposed under the Federal tax laws. More information regarding those considerations appears in our SAI. You are urged to consult your tax adviser regarding the effects of an investment on your tax situation. DISTRIBUTION ARRANGEMENTS Professional Funds Distributor, LLC manages the Funds' distribution efforts and provides assistance and expertise in developing marketing plans and materials, enters into dealer agreement with broker-dealers to sell shares and provide shareholder support services, directly or through affiliates.

Generally, growth-oriented companies have high relative rates of growth and 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 Board of Trustees supervises the investment adviser and establishes policies that the investment adviser must follow in its management activities.
