EATON VANCE ENHANCED EQUITY INCOME FUND

COMMON SHARES
[EATON VANCE LOGO]

INVESTMENT OBJECTIVES. Eaton Vance Enhanced Equity Income Fund (the "Fund") is a newly organized, diversified, closed-end management investment company. The Fund's primary investment objective is to provide current income, with a secondary objective of capital appreciation. The Fund will pursue its investment objectives by investing primarily in a portfolio of large- and mid-capitalization common stocks, seeking to invest primarily in companies with above-average growth and financial strength. Under normal market conditions, the Fund will seek to generate current earnings from option premiums by selling covered call options on a substantial portion of its portfolio securities. There can be no assurance that the Fund will achieve its investment objectives.

INVESTMENT ADVISER AND SUB-ADVISER. The Fund's investment adviser is Eaton Vance Management ("Eaton Vance" or the "Adviser"). As of July 31, 2004, Eaton Vance and its subsidiaries managed approximately $89.4 billion on behalf of funds, institutional clients and individuals, including approximately $33.0 billion in equity fund assets. Eaton Vance has engaged Rampart Investment Management Company ("Rampart" or the "Sub-Adviser") as a sub-adviser to provide advice on and execution of the Fund's options strategy. Rampart, founded in 1983, specializes in options management and trading for institutional and high net worth investors. Rampart managed approximately $1.0 billion in assets as of August 31, 2004.

PORTFOLIO CONTENTS. Under normal market conditions, the Fund will invest at least 80% of its total assets in common stocks. Normally, the Fund will invest primarily in common stocks of large- and mid-capitalization issuers that meet the Fund's selection criteria of above-average growth and financial strength. Under normal market conditions, the Fund expects to invest in at least 75 securities, seeking to reduce the Fund's exposure to individual stock risks. The Fund generally will invest in common stocks on which exchange traded call options are currently available. The Fund will invest primarily in common stocks of U.S. issuers, although the Fund may invest up to 10% of its total assets in securities of foreign issuers.

Under normal market conditions, the Fund intends to pursue its primary investment objective principally by employing an options strategy of writing (selling) covered call options on a substantial portion of its portfolio securities. (continued on inside front cover)

(continued from previous page)

The extent of option writing activity will depend upon market conditions and the Adviser's ongoing assessment of the attractiveness of writing call options on the Fund's stock holdings. Writing covered call options involves a tradeoff between the option premiums received and reduced participation in potential future stock price appreciation. Depending on the Adviser's evaluation, the Fund may write covered call options on varying percentages of the Fund's common stock holdings. The Fund seeks to generate current earnings from option writing premiums and, to a lesser extent, from dividends on stocks held. The Fund's call option-writing program will seek to achieve a high level of net option premiums, while maintaining the potential for capital appreciation in each stock on which options are written up to a defined target price for that stock determined by the Adviser. The Adviser and Sub-Adviser believe that by coordinating their activities they will be able to achieve the Fund's investment objectives. In particular, the Adviser's active management style, which incorporates a research-driven fundamental investment approach, seeks to complement the Sub-Adviser's systematic option methodology, which utilizes a proprietary options analysis and management system.

The Fund may in certain circumstances purchase put options on the Standard & Poor's 500 Composite Stock Price Index, the S&P MidCap 400 Index, any other broad-based securities index deemed suitable for this purpose, and/or on individual stocks held in its portfolio or use other derivative instruments in order to help protect against a decline in the value of its portfolio securities.

EXCHANGE LISTING. The Fund has applied for listing of its common shares on the New York Stock Exchange under the symbol "EOI." Because the Fund is newly organized, its common shares have no history of public trading. The shares of closed-end management investment companies frequently trade at a discount from their net asset value. The returns earned by holders of the Fund's common shares ("Common Shareholders") who purchase their shares in this offering and sell their shares below net asset value will be reduced.

The Fund's net asset value and distribution rate will vary and may be affected by numerous factors, including changes in stock prices, option premiums, market interest rates, dividend rates and other factors. An investment in the Fund may not be appropriate for all investors. There is no assurance that the Fund will achieve its investment objectives.

Prospectus summary

This is only a summary. This summary may not contain all of the information that you should consider before investing in the Fund's common shares. You should review the more detailed information contained in this Prospectus and in the Statement of Additional Information, especially the information set forth under the heading "Investment objectives, policies and risks."

THE FUND

Eaton Vance Enhanced Equity Income Fund (the "Fund") is a newly organized, diversified, closed-end management investment company. The Fund seeks to achieve current income with the potential for capital appreciation. Investments are based on Eaton Vance Management's ("Eaton Vance" or the "Adviser") internal research and ongoing company analysis, which is generally not available to individual investors. Rampart Investment Management Company ("Rampart" or the "Sub-Adviser") has been engaged as a sub-adviser to provide Eaton Vance with advice on and execution of the Fund's option writing strategy. An investment in the Fund may not be appropriate for all investors. There is no assurance that the Fund will achieve its investment objectives.

THE OFFERING

The Fund is offering common shares of beneficial interest, par value $0.01 per share, through a group of underwriters (the "Underwriters") led by UBS Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, and Wachovia Capital Markets, LLC. The common shares of beneficial interest are called "Common Shares." The Underwriters have been granted an option by the Fund to purchase up to additional Common Shares solely to cover orders in excess of Common Shares. The initial public offering price is $20.00 per share. The minimum purchase in this offering is 100 Shares ($2,000). See "Underwriting." Eaton Vance or an affiliate has agreed to (i) reimburse all organizational costs and (ii) pay all offering costs (other than sales loads) that exceed $0.04 per Common Share.

INVESTMENT OBJECTIVES AND POLICIES

The Fund's primary investment objective is to provide current income, with a secondary objective of capital appreciation. The Fund will pursue its investment objectives by investing primarily in a portfolio of large- and mid-capitalization common stocks, seeking to invest primarily in companies with above-average growth and financial strength. Under normal market conditions, the Fund will seek to generate current earnings from option premiums by selling covered call options on a substantial portion of its portfolio securities. There can be no assurance that the Fund will achieve its investment objectives.

Under normal market conditions, the Fund will invest at least 80% of its total assets in common stocks. Normally, the Fund will invest primarily in common stocks of large- and mid-capitalization issuers that meet the Fund's selection criteria of above-average growth and financial strength. Under normal market conditions, the Fund expects to invest in at least 75 securities, seeking to reduce the Fund's exposure to individual stock risks. The Fund generally will invest in common stocks on which exchange traded call options are currently available. The Fund will invest primarily in common stocks of U.S. issuers, although the Fund may invest up to 10% of its total assets in securities of foreign issuers, including American Depositary Receipts ("ADRs"), Global Depositary Receipts ("GDRs") and European Depositary Receipts ("EDRs").

Eaton Vance generally considers large-capitalization companies to be those companies having market capitalizations equal to or greater than the median capitalization of the companies included in the Standard & Poor's 500 Composite Stock Price Index ("S&P 500"). As of August 31, 2004, the median capitalization of companies in the S&P 500 was approximately $9.3 billion. Eaton Vance

1

generally considers mid-capitalization companies to be those companies having market capitalizations within the range of capitalizations for the S&P MidCap 400 Index ("S&P MidCap 400").

Under normal market conditions, the Fund intends to pursue its primary investment objective principally by employing an options strategy of writing (selling) covered call options on a substantial portion of its portfolio securities. The extent of option writing activity will depend upon market conditions and the Adviser's ongoing assessment of the attractiveness of writing call options on the Fund's stock holdings. Writing covered call options involves a tradeoff between the option premiums received and reduced participation in potential future stock price appreciation. Depending on the Adviser's evaluation, the Fund may write covered call options on varying percentages of the Fund's common stock holdings. The Fund seeks to generate current earnings from option writing premiums and, to a lesser extent, from dividends on stocks held. The Fund may in certain circumstances purchase put options on the S&P 500, the S&P MidCap 400, any other broad-based securities index deemed suitable for this purpose, and/or on individual stocks held in its portfolio or use other derivative instruments in order to help protect against a decline in the value of its portfolio securities.

The Fund normally expects that its investments will be invested across a broad range of industries and market sectors. The Fund may not invest 25% or more of its total assets in the securities of issuers in any single industry or group of industries.

INVESTMENT STRATEGY

A team of Eaton Vance investment professionals with extensive experience in equity research and management is responsible for the overall management of the Fund's investments. Rampart Investment Management Company ("Rampart" or the "Sub-Adviser") has been engaged as a sub-adviser to provide Eaton Vance with advice on and execution of the Fund's option writing strategy. The Fund's investments are actively managed, and securities and other investments may be bought or sold on a daily basis.

The Adviser believes that a strategy combining active equity portfolio management with a systematic program of covered call option writing can provide potentially attractive long-term returns. The Adviser further believes that a strategy of owning common stocks in conjunction with writing covered call options on a substantial portion of the stocks held should generally provide returns that are superior to simply owning the same stocks under three different stock market scenarios: (1) down-trending equity markets; (2) flat market conditions; and (3) moderately rising equity markets. In the Adviser's opinion, only in more strongly rising equity markets would the stock-plus-covered calls strategy generally be expected to underperform the stocks held. For these purposes, the Adviser considers more strongly rising equity market conditions to exist whenever the current annual rate of return for U.S. stocks materially exceeds the long-term historical average of stock market returns. The Adviser considers moderately rising equity market conditions to exist whenever current annual returns on U.S. common stocks are positive, but not materially higher than the long-term historical average of stock market returns.

Investment decisions for the Fund will be made primarily on the basis of fundamental research. The Eaton Vance portfolio managers will utilize information provided by, and the expertise of, the Adviser's research staff in making investment decisions. The Adviser believes that investments in companies with above average growth and financial strength should provide attractive opportunities for investment appreciation. The Adviser seeks to identify such stocks by focusing, without limitation, on issuers with the following characteristics: (1) sustainable competitive advantages, (2) predictable and dependable cash flows, (3) high quality management teams and (4) solid balance sheets. Many of these considerations are subjective. In addition to its careful research based analysis in selecting investments for the Fund, the Adviser will also place a strong emphasis on the ongoing evaluation of portfolio holdings and the appropriate time and circumstances to sell or reduce a holding. In this regard, the Adviser may sell a stock when it believes it is fully valued, the fundamentals of the company

2

deteriorate, the stock's price falls below its acquisition cost, management fails to execute its strategy or to pursue other more attractive investment opportunities, among other reasons.

The Adviser and Sub-Adviser believe that by coordinating their activities, they will be able to achieve the Fund's investment objectives. In particular, the Adviser's active management style seeks to complement the Sub-Adviser's systematic option methodology. The Fund's call option-writing program will seek to achieve a high level of net option premiums, while maintaining the potential for capital appreciation in each stock on which options are written up to a defined target price for that stock determined by the Adviser. To achieve this goal, Rampart utilizes proprietary options management and options trading analytical tools (Rampart Options Management System (ROMS)). Additionally, the Adviser's long-term investment approach and low core turnover of the underlying portfolio allows for more efficient option overlay potential. Transaction costs associated with the Fund's options strategy will vary depending on market circumstances and other factors. Although it is not possible to accurately predict such costs because of this variability, the Adviser estimates that such costs on an annualized basis may range from between 0.20% and 0.30% assuming the same offering size assumed for purposes of presenting the information set forth under "Summary of Fund expenses." There can be no certainty that upon changing market conditions such costs will fall within this range.

The Fund expects initially to write primarily exchange-listed call options on individual stocks held in the Fund's portfolio (rather than S&P 500, S&P MidCap 400, or other index options), primarily with shorter maturities (typically two to six months until expiration) and primarily at exercise prices approximately equal to or slightly above the current stock price when written. When an option-writing program is established for a particular stock, options will typically be written on a portion of the total stock position, which may allow for upside potential. If the stock price increases, the Fund will normally look to buy back the call options written and to sell new call options at higher exercise prices (up to the target price determined by the Adviser) on a greater number of shares. When a stock's price moves to or above its target price, the Adviser will evaluate the stock and option-writing program and determine whether to raise its target price and continue to hold the stock and write covered call options or, alternatively, whether to deliver the stock in settlement of the option position or otherwise exit the position by buying back the options written and selling the stock. If the stock price declines, the Fund will normally seek to buy back the call options written and to sell new call options at lower exercise prices on fewer shares. The Fund will seek to execute option rolls (as described above) such that the premium received from writing new options generally exceeds the amounts paid to close the positions being replaced. The Fund may also write covered call options with different characteristics and managed differently than described in this paragraph.

In addition to the intended strategy of selling covered call options, the Fund may invest up to 20% of its total assets in other derivative instruments acquired for hedging, risk management and investment purposes (to gain exposure to securities, securities markets, markets indices and/or currencies consistent with its investment objectives and policies), provided that no more than 10% of the Fund's total assets may be invested in such derivative instruments acquired for non-hedging purposes. Among other derivative strategies, the Fund may purchase put options on the S&P 500, the S&P MidCap 400, any other broad-based securities index deemed suitable for this purpose, and/or on individual stocks held in its portfolio or use other derivative instruments in order to help protect against a decline in the value of its portfolio securities. Derivative instruments may be used by the Fund to enhance returns or as a substitute for the purchase or sale of securities.

The foregoing policies relating to investment in common stocks and options writing are the Fund's primary investment policies. In addition to its primary investment policies, the Fund may invest to a limited extent in other types of securities and engage in certain other investment practices.

LISTING

The Fund has applied for listing of its Common Shares on the New York Stock Exchange under the symbol "EOI."

INVESTMENT ADVISER, ADMINISTRATOR AND SUB-ADVISER

Eaton Vance, a direct wholly-owned subsidiary of Eaton Vance Corp., is the Fund's investment adviser and administrator. The Adviser and its subsidiaries managed approximately $89.4 billion on behalf of funds, institutional clients and individuals as of July 31, 2004, including approximately $33.0 billion in equity fund assets. Twenty-eight of the funds managed by Eaton Vance are closed-end funds. Eaton Vance has engaged Rampart as a sub-adviser to provide advice on and execution of the Fund's options strategy. Rampart, founded in 1983, specializes in option management and trading for institutional and high net worth investors. Rampart managed approximately $1.0 billion in assets as of August 31, 2004. See "Management of the Fund."

DISTRIBUTIONS

Commencing with the Fund's first distribution, the Fund intends to make regular monthly distributions to Common Shareholders based upon the Fund's projected annual cash available from option premiums and dividends. For distribution purposes, "cash available from option premiums and dividends" will consist of the total proceeds of options sales plus dividends and interest received, less amounts paid to purchase options and Fund expenses. The Fund's distribution rate may be adjusted from time-to-time. The Board may modify this distribution policy at any time without obtaining the approval of Common Shareholders. The initial distribution is expected to be declared approximately 45-60 days and paid approximately 60-90 days after the completion of this offering, depending on market conditions.

The Fund's annual cash available from options premiums and dividends will likely differ from annual net investment income. The investment income of the Fund will consist of all dividend and interest income accrued on portfolio investments, short-term capital gain (including short-term gains on terminated option positions and gains on the sale of portfolio investments held for one year or less) in excess of long-term capital loss and income from certain hedging transactions, less all expenses of the Fund. Expenses of the Fund will be accrued each day. Over time, all of the Fund's investment company taxable income will be distributed. In addition, at least annually, the Fund intends to distribute any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss). To the extent that that Fund's net investment income and net capital gain for any year exceed the total monthly distributions paid during the year, the Fund will make a special distribution at or near year-end of such excess amount as may be required. If the Fund's total monthly distributions in any year exceed the amount of its net investment income and net capital gain for the year, any such excess would be characterized as a return of capital. Under the 1940 Act, for any distribution that includes amounts from sources other than net income, the Fund is required to provide Common Shareholders a written statement regarding the components of such distribution.

To permit the Fund to maintain more stable distributions, distribution rates will be based on projected annual cash available from options premiums and dividends. As a result, the distributions paid by the Fund for any particular month may be more or less than the amount of cash available from options premiums and dividends for that month. In such circumstances, the Fund may have to sell a portion of its investment portfolio to make a distribution at a time when independent investment judgment might not dictate such action. Undistributed net investment income is included in the Common Shares' net asset value, and, correspondingly, distributions from net investment income will reduce the Common Shares' net asset value.

Common Shareholders may elect automatically to reinvest some or all of their distributions in additional Common Shares under the Fund's dividend reinvestment plan. See "Distributions" and "Dividend reinvestment plan."

DIVIDEND REINVESTMENT PLAN

The Fund has established a dividend reinvestment plan (the "Plan"). Under the Plan, a Common Shareholder may elect to have all distributions automatically reinvested in additional Common Shares

4

either purchased in the open market or newly issued by the Fund if the Common Shares are trading at or above their net asset value. Common Shareholders may elect to participate in the Plan by completing the dividend reinvestment plan application form. Common Shareholders who do not elect to participate in the Plan will receive all distributions in cash paid by check mailed directly to them by PFPC Inc., as dividend paying agent. Common Shareholders who intend to hold their Common Shares through a broker or nominee should contact such broker or nominee to determine whether or how they may participate in the Plan. See "Dividend reinvestment plan."

CLOSED-END STRUCTURE

Closed-end funds differ from open-end management investment companies (commonly referred to as mutual funds) in that closed-end funds generally list their shares for trading on a securities exchange and do not redeem their shares at the option of the shareholder. By comparison, mutual funds issue securities that are redeemable at net asset value at the option of the shareholder and typically engage in a continuous offering of their shares. Mutual funds are subject to continuous asset in-flows and out-flows that can complicate portfolio management, whereas closed-end funds generally can stay more fully invested in securities consistent with the closed-end fund's investment objectives and policies. In addition, in comparison to open-end funds, closed-end funds have greater flexibility in the employment of financial leverage, and in the ability to make certain types of investments. Shares of closed-end funds listed on an exchange may be purchased and sold throughout each trading day, whereas purchases and sales of mutual funds are generally effected as of the close of market trading. However, shares of closed-end funds frequently trade at a discount from their net asset value. In recognition of the possibility that the Common Shares might trade at a discount to net asset value and that any such discount may not be in the interest of Common Shareholders, the Fund's Board of Trustees (the "Board"), in consultation with Eaton Vance, from time to time may review possible actions to reduce any such discount. The Board might consider open market repurchases or tender offers for Common Shares at net asset value. There can be no assurance that the Board will decide to undertake any of these actions or that, if undertaken, such actions would result in the Common Shares trading at a price equal to or close to net asset value per Common Share. The Board might also consider the conversion of the Fund to an open-end mutual fund. The Board believes, however, that the closed-end structure is desirable, given the Fund's investment objectives and policies. Investors should assume, therefore, that it is highly unlikely that the Board would vote to convert the Fund to an open-end investment company. Although the Fund has no current intention to issue preferred shares, investors should note that any possible future issuance of preferred shares to provide investment leverage could make a conversion to open-end form more difficult because of the voting rights of preferred shareholders, the costs of redeeming preferred shares and other factors. See "Description of capital structure."

SPECIAL RISK CONSIDERATIONS

NO OPERATING HISTORY
The Fund is a closed-end investment company with no history of operations and is designed for long-term investors and not as a trading vehicle.

INVESTMENT AND MARKET RISK
An investment in Common Shares is subject to investment risk, including the possible loss of the entire principal amount invested. An investment in Common Shares represents an indirect investment in the securities owned by the Fund, which are generally traded on a securities exchange or in the over-the-counter markets. The value of these securities, like other market investments, may move up or down, sometimes rapidly and unpredictably. In addition, by writing (selling) call options on the equity securities held in the Fund's portfolio, the capital appreciation potential of such securities will be limited to the difference between the exercise price of the call options written and the purchase price of the equity security underlying such options. The Common Shares at any point in time may be worth less than the original investment, even after taking into account any reinvestment of distributions.

5

ISSUER RISK
The value of securities held by the Fund may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods and services.

EQUITY RISK
At least 80% of the Fund's total assets will be invested in common stocks and therefore a principal risk of investing in the Fund is equity risk. Equity risk is the risk that securities held by the Fund will fall due to general market or economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, and the particular circumstances and performance of particular companies whose securities the Fund holds. Although common stocks have historically generated higher average returns than fixed-income securities over the long term, common stocks also have experienced significantly more volatility in returns. An adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common equity securities in which the Fund will invest are structurally subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Finally, common stock prices may be sensitive to rising interest rates, as the costs of capital rise and borrowing costs increase.

RISKS ASSOCIATED WITH OPTIONS ON SECURITIES
There are numerous risks associated with transactions in options on securities. A decision as to whether, when and how to use options involves the exercise of skill and judgment, and even a well-conceived transaction may be unsuccessful to some degree because of market behavior or unexpected events. As the writer of a covered call option, the Fund forgoes, during the option's life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the option premium received and the exercise price of the call, but has retained the risk of loss, minus the option premium received, should the price of the underlying security decline. The writer of an option has no control over when during the exercise period of the option it may be required to fulfill its obligation as a writer of the option. Once an option writer has received an exercise notice, it cannot effect a closing purchase transaction in order to terminate its obligation under the option and must deliver the underlying security at the exercise price. Thus, the use of options may require the Fund to sell portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the Fund can realize on an investment, or may cause the Fund to hold a security that it might otherwise sell.

The value of options may also be adversely affected if the market for such options becomes less liquid or smaller. There can be no assurance that a liquid market will exist when the Fund seeks to close out an option position either, in the case of a call option written, by buying the option, or, in the case of a purchased put option, by selling the option. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both;
(iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or the Options Clearing Corporation (the "OCC") may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled to discontinue the trading of options (or a particular class or series of options) at some future date. If trading were discontinued, the secondary

6

market on that exchange (or in that class or series of options) would cease to exist. However, outstanding options on that exchange that had been issued by the OCC as a result of trades on that exchange would continue to be exercisable in accordance with their terms. The Fund's ability to terminate over-the-counter options will be more limited than with exchange-traded options and may involve the risk that broker-dealers participating in such transactions will not fulfill their obligations. If the Fund were unable to close out a covered call option that it had written on a security, it would not be able to sell the underlying security unless the option expired without exercise.

The hours of trading for options may not conform to the hours during which the underlying securities are traded. To the extent that the options markets close before the markets for the underlying securities, significant price and rate movements can take place in the underlying markets that would not be reflected concurrently in the options markets. Call options are marked to market daily and their value will be affected by changes in the value of and dividend rates of the underlying common stocks, changes in interest rates, changes in the actual or perceived volatility of the stock market and the underlying common stocks and the remaining time to the options' expiration. Additionally, the exercise price of an option may be adjusted downward before the option's expiration as a result of the occurrence of certain corporate events affecting the underlying equity security, such as extraordinary dividends, stock splits, merger or other extraordinary distributions or events. A reduction in the exercise price of an option would reduce the Fund's capital appreciation potential on the underlying security.

If the Fund purchases put options for hedging or risk management purposes, the Fund will be subject to the following additional risks. A put option acquired by the Fund and not sold prior to expiration will expire worthless if the price of the stock or index at expiration exceeds the exercise price of the option, thereby causing the Fund to lose its entire investment in the option. If restrictions on exercise were imposed, the Fund might be unable to exercise an option it had purchased. If the Fund were unable to close out an option that it had purchased, it would have to exercise the option in order to realize any profit or the option may expire worthless. Stock market indices on which the Fund may purchase options positions will not mirror the Fund's actual portfolio holdings. The effectiveness of index put options as hedges against declines in the Fund's stock portfolio will be limited to the extent that the performance of the underlying index does not correlate with that of the Fund's holdings.

LIMITATION ON OPTION WRITING
The number of call options the Fund can write is limited by the number of shares of common stock the Fund holds, and further limited by the fact that listed call options on individual common stocks generally trade in units representing 100 shares of the underlying stock. Furthermore, the Fund's options transactions will be subject to limitations established by each of the exchanges, boards of trade or other trading facilities on which such options are traded. These limitations govern the maximum number of options in each class which may be written or purchased by a single investor or group of investors acting in concert, regardless of whether the options are written or purchased on the same or different exchanges, boards of trade or other trading facilities or are held or written in one or more accounts or through one or more brokers. Thus, the number of options which the Fund may write or purchase may be affected by options written or purchased by other investment advisory clients of the Adviser or Sub-Adviser. An exchange, board of trade or other trading facility may order the liquidation of positions found to be in excess of these limits, and may impose certain other sanctions. The Fund will not write "naked" or uncovered call options.

RISKS OF MID-CAP COMPANIES
The Fund may invest substantially in companies whose market capitalization is considered middle sized or "mid-cap." Mid-cap companies often are newer or less established companies than larger companies. Investments in mid-cap companies carry additional risks because earnings of these companies tend to be less predictable; they often have limited product lines, markets, distribution channels or financial resources; and the management of such companies may be dependent upon one or a few key people. The market movements of equity securities of mid-cap companies may be more

7

abrupt or erratic than the market movements of equity securities of larger, more established companies or the stock market in general. Historically, mid-cap companies have sometimes gone through extended periods when they did not perform as well as larger companies. In addition, equity securities of mid-cap companies generally are less liquid than those of larger companies. This means that the Fund could have greater difficulty selling such securities at the time and price that the Fund would like.

RISKS OF GROWTH STOCK INVESTING
The Fund expects to invest substantially in stocks with "growth" characteristics. Growth stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks. Growth stocks tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, growth stocks tend to be sensitive to changes in their earnings and more volatile than other types of stocks.

DISTRIBUTION RISK
The monthly distributions Common Shareholders receive from the Fund will be based primarily on the level of net option premiums and the dividends received by the Fund. Net option premiums and dividend payments the Fund receives in respect of its portfolio securities can vary widely over the short- and long-term. If stock prices or stock price volatility declines, the level of premiums from options writing and the amounts available for distribution from options activity will likely decrease as well. Payments to purchase put options and to close written call options will reduce amounts available for distribution from call option premiums received and proceeds of closing put options. Dividends on common stocks are not fixed but are declared at the discretion of the issuer's board of directors. There is no guarantee that the issuers of common stocks in which the Fund invests will declare dividends in the future or that if declared they will remain at current levels or increase over time. Dividends on any preferred stocks in which the Fund may invest are not guaranteed and certain issues of preferred stock held by the Fund may be called by the issuer.

FOREIGN SECURITY RISK
The value of foreign securities is affected by changes in currency rates, foreign tax laws (including withholding tax), government policies (in this country or abroad), relations between nations and trading, settlement, custodial and other operational risks. In addition, the costs of investing abroad are generally higher than in the United States, and foreign securities markets may be less liquid, more volatile and less subject to governmental supervision than markets in the United States. Foreign investments also could be affected by other factors not present in the United States, including expropriation, armed conflict, confiscatory taxation, lack of uniform accounting and auditing standards, less publicly available financial and other information and potential difficulties in enforcing contractual obligations. As an alternative to holding foreign-traded securities, the Fund may invest in dollar-denominated securities of foreign companies that trade on U.S. exchanges or in the U.S. over-the-counter market (including depositary receipts, which evidence ownership in underlying foreign securities). Since the Fund may invest in securities denominated or quoted in currencies other than the U.S. dollar, the Fund will be affected by changes in foreign currency exchange rates (and exchange control regulations) which affect the value of investments in the Fund and the accrued income and appreciation or depreciation of the investments in U.S. dollars. Changes in foreign currency exchange rates relative to the U.S. dollar will affect the U.S. dollar value of the Fund's assets denominated in that currency and the Fund's return on such assets as well as any temporary uninvested reserves in bank deposits in foreign currencies. In addition, the Fund will incur costs in connection with conversions between various currencies.

INTEREST RATE RISK
The level of premiums from call options writing and the amounts available for distribution from the Fund's options activity may decrease in declining interest rate environments. Any preferred stocks paying fixed dividend rates in which the Fund invests, will likely change in value as market interest

8

rates change. When interest rates rise, the market value of such securities generally will fall. To the extent that the Fund invests in preferred stocks, the net asset value and price of the Common Shares may decline if market interest rates rise. Interest rates are currently low relative to historic levels. During periods of declining interest rates, an issuer of preferred stock may exercise its option to redeem securities prior to maturity, forcing the Fund to reinvest in lower yielding securities. This is known as call risk. During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected payments. This may lock in a below market yield, increase the security's duration, and reduce the value of the security. This is known as extension risk. The value of the Fund's common stock investments may also be influenced by changes in interest rates.

SECTOR RISK
The Fund may invest a significant portion of its assets in securities of issuers in any single industry or sector of the economy (a broad based economic segment that may include many distinct industries) if companies in that industry or sector meet the Fund's investment criteria. If the Fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries or sectors of the economy. A "sector" is a broader economic segment that may include many different industries. This may make the Fund more susceptible to adverse economic, political, or regulatory occurrences affecting these sectors. As the percentage of the Fund's assets invested in a particular sector increases, so does the potential for fluctuation in the net asset value of Common Shares. The Fund may not invest 25% or more of its total assets in the securities of issuers in any single industry or group of industries.

DERIVATIVES RISK
In addition to writing covered call options, the risks of which are described above, the Fund may invest up to 20% of its total assets in other derivative investments acquired for hedging, risk management and investment purposes. Derivative transactions including options on securities and securities indices and other transactions in which the Fund may engage (such as futures contracts and options thereon, swaps and short sales) may subject the Fund to increased risk of principal loss due to unexpected movements in stock prices, changes in stock volatility levels and interest rates, and imperfect correlations between the Fund's securities holdings and indices upon which derivative transactions are based. The Fund also will be subject to credit risk with respect to the counterparties to any over-the-counter derivatives contracts purchased by the Fund. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative contract in a bankruptcy or other reorganization proceeding. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances.

LIQUIDITY RISK
The Fund may invest up to 15% of its total assets in securities for which there is no readily available trading market or which are otherwise illiquid. The Fund may not be able readily to dispose of such securities at prices that approximate those at which the Fund could sell such securities if they were more widely traded and, as a result of such illiquidity, the Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. In addition, the limited liquidity could affect the market price of the securities, thereby adversely affecting the Fund's net asset value.

INFLATION RISK
Inflation risk is the risk that the purchasing power of assets or income from investment will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Shares and distributions thereon can decline.

9

MARKET PRICE OF COMMON SHARES
The shares of closed-end management investment companies often trade at a discount from their net asset value, and the Fund's Common Shares may likewise trade at a discount from net asset value. The trading price of the Fund's Common Shares may be less than the public offering price. The returns earned by Common Shareholders who purchased their Common Shares in this offering and sell their Common Shares below net asset value will be reduced.

FINANCIAL LEVERAGE
Although the Fund has no current intention to do so, the Fund is authorized to utilize leverage through the issuance of preferred shares and/or borrowings, including the issuance of debt securities. In the event that the Fund determines in the future to utilize investment leverage, there can be no assurance that such a leveraging strategy will be successful during any period in which it is employed. Leverage creates risks for Common Shareholders, including the likelihood of greater volatility of net asset value and market price of the Common Shares and the risk that fluctuations in distribution rates on any preferred shares or fluctuations in borrowing costs may affect the return to Common Shareholders. To the extent the income derived from securities purchased with proceeds received from leverage exceeds the cost of leverage, the Fund's distributions will be greater than if leverage had not been used. Conversely, if the income from the securities purchased with such proceeds is not sufficient to cover the cost of leverage, the amount available for distribution to Common Shareholders will be less than if leverage had not been used. In the latter case, Eaton Vance, in its best judgment, may nevertheless determine to maintain the Fund's leveraged position if it deems such action to be appropriate. The costs of an offering of preferred shares and/or a borrowing program would be borne by Common Shareholders and consequently would result in a reduction of the net asset value of Common Shares. In addition, the fee paid to Eaton Vance will be calculated on the basis of the Fund's average daily gross assets, including proceeds from the issuance of preferred shares and/or borrowings, so the fees will be higher when leverage is utilized. In this regard, holders of preferred shares do not bear the investment advisory fee. Rather, Common Shareholders bear the portion of the investment advisory fee attributable to the assets purchased with the proceeds of the preferred shares offering.

MANAGEMENT RISK
The Fund is subject to management risk because it is an actively managed portfolio. Eaton Vance, Rampart and the individual portfolio managers will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results. The Fund may be subject to additional management risk because the Fund's options program will require effective coordination between the Adviser and the Sub-Adviser.

MARKET DISRUPTION
The terrorist attacks in the United States on September 11, 2001 had a disruptive effect on the securities markets. These terrorist attacks and related events, including the war in Iraq, its aftermath, and continuing occupation of Iraq by coalition forces, have raised short-term market risk and may have adverse long-term effects on U.S. and world economies and markets. A similar disruption of the financial markets could impact trading in common stocks and stock options, interest rates, credit risk, inflation and other factors relating to the Common Shares. The Fund cannot predict the effects of similar events in the future on the U.S. economy and securities markets.

ANTI-TAKEOVER PROVISIONS
The Fund's Agreement and Declaration of Trust includes provisions that could have the effect of limiting the ability of other persons or entities to acquire control of the Fund or to change the composition of its Board. See "Description of capital structure--Anti-takeover provisions in the Declaration of Trust."

(1) Eaton Vance or an affiliate has agreed to reimburse all organizational costs and pay all offering costs (other than sales load) that exceed $0.04 per Common Share (0.20% of the offering price).

(2) You will be charged a $5.00 service charge and pay brokerage charges if you direct the plan agent to sell your Common Shares held in a dividend reinvestment account.

(3) Estimated expenses based on the current fiscal year.

The expenses shown in the table are based on estimated amounts for the Fund's first year of operations and assume that the Fund issues approximately 12,500,000 Common Shares. See "Management of the Fund" and "Dividend reinvestment plan."

EXAMPLE

The following Example illustrates the expenses that you would pay on a $1,000 investment in Common Shares (including the sales load of $45, estimated offering expenses of this offering of $2), assuming (1) total annual expenses of 1.20% of net assets attributable to Common Shares and (2) a 5% annual return(1):

1 YEAR   3 YEARS   5 YEARS   10 YEARS

The Fund

Eaton Vance Enhanced Equity Income Fund (the "Fund") is a newly organized, diversified, closed-end management investment company registered under the Investment Company Act of 1940, as amended (the "1940 Act" or the "Investment Company Act"). The Fund was organized as a Massachusetts business trust on August 11, 2004 pursuant to a Declaration of Trust governed by the laws of The Commonwealth of Massachusetts and has no operating history. The Fund's principal office is located at The Eaton Vance Building, 255 State Street, Boston, Massachusetts 02109, and its telephone number is 1-800-225-6265.

This Prospectus relates to the initial public offering of the Fund's common shares of beneficial interest, $0.01 par value (the "Common Shares"). See "Underwriting."

Use of proceeds

The net proceeds of this offering of Common Shares will be approximately $ (or $ assuming exercise of the Underwriters' over-allotment option in full), which, after payment of the estimated offering expenses, will be invested in accordance with the Fund's investment objectives and policies as soon as practicable, but, in no event, under normal market conditions, later than three months after the receipt thereof. Pending such investment, the proceeds may be invested in high-quality, short-term debt securities, cash and/or cash equivalents. Eaton Vance or an affiliate has agreed to (i) reimburse all organizational costs and (ii) pay all offering costs of the Fund (other than sales loads) that exceed $0.04 per Common Share.

Investment objectives, policies and risks

INVESTMENT OBJECTIVES

The Fund's primary investment objective is to provide current income, with a secondary objective of capital appreciation. The Fund will pursue its investment objectives by investing primarily in a portfolio of large and mid-capitalization common stocks, seeking to invest primarily in companies with above-average growth and financial strength. Under normal market conditions, the Fund will seek to generate current earnings from option premiums by selling covered call options on a substantial portion of its portfolio securities. There can be no assurance that the Fund will achieve its investment objectives.

PRIMARY INVESTMENT POLICIES

GENERAL COMPOSITION OF THE FUND
Under normal market conditions, the Fund will invest at least 80% of its total assets in common stocks. Normally, the Fund will invest primarily in common stocks of large- and mid-capitalization issuers that meet the Fund's selection criteria of above-average growth and financial strength. Under normal market conditions, the Fund expects to invest in at least 75 securities, seeking to reduce the Fund's exposure to individual stock risks. The Fund generally will invest in common stocks on which exchange traded call options are currently available. The Fund will invest primarily in common stocks of U.S. issuers, although the Fund may invest up to 10% of its total assets in securities of foreign issuers, including American Depositary Receipts ("ADRs"), Global Depositary Receipts ("GDRs") and European Depositary Receipts ("EDRs").


12

INVESTMENT OBJECTIVES, POLICIES AND RISKS

Eaton Vance generally considers large-capitalization companies to be those companies having market capitalizations equal to or greater than the median capitalization of the companies included in the Standard & Poor's 500 Composite Stock Price Index ("S&P 500"). As of August 31, 2004, the median market capitalization of companies in the S&P 500 was approximately $9.3 billion. Eaton Vance generally considers mid-capitalization companies to be those companies having market capitalizations within the range of capitalizations for the Standard & Poor's MidCap 400 Index ("S&P MidCap 400").

The Fund's policy of investing, under normal market circumstances, at least 80% of its total assets in common stocks is not considered to be fundamental by the Fund and can be changed without a vote of the Fund's shareholders. However, this policy may only be changed by the Fund's Board of Trustees (the "Board") following the provision of 60 days prior written notice to the Fund's shareholders.

Under normal market conditions, the Fund intends to pursue its primary investment objective principally by employing an options strategy of writing (selling) covered call options on a substantial portion of its portfolio securities. The extent of option writing activity will depend upon market conditions and the Adviser's ongoing assessment of the attractiveness of writing call options on the Fund's stock holdings. Writing covered call options involves a tradeoff between the option premiums received and reduced participation in potential future stock price appreciation. Depending on the Adviser's evaluation, the Fund may write covered call options on varying percentages of the Fund's common stock holdings. The Fund seeks to generate current earnings from option writing premiums and, to a lesser extent, from dividends on stocks held.

The Fund may in certain circumstances purchase put options on the S&P 500, S&P MidCap 400, any other broad-based securities index deemed suitable for this purpose, and/or on individual stocks held in its portfolio or use other derivative instruments in order to help protect against a decline in the value of its portfolio securities. The premiums paid to acquire any such put options will reduce the amounts available for distribution to Common Shareholders from options activities.

The Fund normally expects that its investments will be invested across a broad range of industries and market sectors. The Fund may, however, invest up to any amount less than 25% of its total assets in the securities of issuers in any single industry or group of industries. See "Risk considerations--Sector risk."

INVESTMENT STRATEGY
A team of Eaton Vance investment professionals with extensive experience in equity research and management is responsible for the overall management of the Fund's investments. Rampart Investment Management Company ("Rampart" or the "Sub-Adviser") has been engaged as a sub-adviser to provide the Fund with advice on and execution of its option writing strategy. The Fund's investments are actively managed, and securities and other investments may be bought or sold on a daily basis.

The Adviser believes that a strategy combining active equity portfolio management with a systematic program of covered call option writing can provide potentially attractive long-term returns. The Adviser further believes that a strategy of owning common stocks in conjunction with writing covered call options on a substantial portion of the stocks held should generally provide returns that are superior to simply owning the same stocks under three different stock market scenarios: (1) Down-trending equity markets; (2) flat market conditions; and (3) moderately rising equity markets. In the Adviser's opinion, only in more strongly rising equity markets would the stock-plus-covered calls strategy generally be expected to underperform the stocks held. For these purposes, the Adviser considers more strongly rising equity market conditions to exist whenever the current annual rate of return for U.S. stocks materially exceeds the long-term historical average of stock market returns. The Adviser considers moderately rising equity market conditions to exist whenever current annual returns


13

INVESTMENT OBJECTIVES, POLICIES AND RISKS

on U.S. common stocks are positive, but not materially higher than the long-term historical average of stock market returns.

Investment decisions for the Fund will be made primarily on the basis of fundamental research. The Eaton Vance portfolio managers will utilize information provided by, and the expertise of, the Adviser's research staff in making investment decisions. The Adviser believes that investments in companies with above average growth and financial strength should provide attractive opportunities for investment appreciation. The Adviser seeks to identify such stocks by focusing, without limitation, on issuers with the following characteristics: (1) sustainable competitive advantages, (2) predictable and dependable cash flows, (3) high quality management teams and (4) solid balance sheets. Many of these considerations are subjective. In addition to its careful research based analysis in selecting investments for the Fund, the Adviser also places a strong emphasis on the ongoing evaluation of portfolio holdings and the appropriate time and circumstances to sell or reduce a holding. In this regard, the Adviser may sell a stock when it believes it is fully valued, the fundamentals of a company deteriorate, a stock's price falls below its acquisition cost, management fails to execute its strategy or to pursue other more attractive investment opportunities, among other reasons.

The Adviser and Sub-Adviser believe that by coordinating their activities, they will be able to achieve the Fund's investment objectives. In particular, the Adviser's active management style seeks to complement the Sub-Adviser's systematic option methodology. The Fund's call option-writing program will seek to achieve a high level of net option premiums, while maintaining the potential for capital appreciation in each stock on which options are written up to a defined target price for that stock determined by the Adviser. To achieve this goal, Rampart utilizes proprietary options management and options trading analytical tools (Rampart Options Management System (ROMS)). Additionally, the Adviser's long-term investment approach and low core turnover of the underlying portfolio allows for more efficient option overlay potential. Transaction costs associated with the Fund's options strategy will vary depending on market circumstances and other factors. Although it is not possible to accurately predict such costs because of this variability, the Adviser estimates that such costs on an annualized basis may range from between 0.20% to 0.30% assuming the same offering size assumed for purposes of presenting the information set forth under "Summary of Fund expenses." There can be no certainty that upon changing market conditions such costs will fall within this range.

The Fund expects initially to write primarily exchange-listed call options on individual stocks held in the Fund's portfolio (rather than S&P 500, S&P MidCap 400 or other index options), primarily with shorter maturities (typically two to six months until expiration) and primarily at exercise prices approximately equal to or slightly above the current stock price when written. When an option-writing program is established for a particular stock, options will typically be written on a portion of the total stock position, which may allow for upside potential. If the stock price increases, the Fund will normally look to buy back the call options written and to sell new call options at higher exercise prices (up to the target price determined by the Adviser) on a greater number of shares. When a stock's price moves to or above its target price, the Adviser will evaluate the stock and option-writing program and determine whether to raise its target price and continue to hold the stock and write covered call options or, alternatively, whether to deliver the stock in settlement of the option position or otherwise exit the position by buying back the options written and selling the stock. If the stock price declines, the Fund will normally seek to buy back the call options written and to sell new call options at lower exercise prices on fewer shares. The Fund will seek to execute option rolls (as described above) such that the premium received from writing new options generally exceeds the amounts paid to close the positions being replaced. The Fund may also write covered call options with different characteristics and managed differently than described in this paragraph.

In addition to the intended strategy of selling covered call options, the Fund may invest up to 20% of its total assets in other derivative instruments acquired for hedging, risk management and investment


14

INVESTMENT OBJECTIVES, POLICIES AND RISKS

purposes (to gain exposure to securities, securities markets, markets indices and/or currencies consistent with its investment objectives and policies), provided that no more than 10% of the Fund's total assets may be invested in such derivative instruments acquired for non-hedging purposes. Among other derivative strategies, the Fund may purchase put options on the S&P 500, the S&P MidCap 400, any other broad-based securities index deemed suitable for this purpose, and/or on individual stocks held in its portfolio in order to help protect against a decline in the value of its portfolio securities. Derivative instruments may be used by the Fund to enhance returns or as a substitute for the purchase or sale of securities.

COMMON STOCKS
Under normal market conditions, the Fund will invest at least 80% of its total assets in common stocks. Common stock represents an equity ownership interest in the issuing corporation. Holders of common stock generally have voting rights in the issuer and are entitled to receive common stock dividends when, as and if declared by the corporation's board of directors. Common stock normally occupies the most subordinated position in an issuer's capital structure. Returns on common stock investments consist of any dividends received plus the amount of appreciation or depreciation in the value of the stock. The Fund will have substantial exposure to common stocks.

Although common stocks have historically generated higher average returns than fixed-income securities over the long term and particularly during periods of high or rising concerns about inflation, common stocks also have experienced significantly more volatility in returns and may not maintain their real value during inflationary periods. An adverse event, such as an unfavorable earnings report, may depress the value of a particular common stock held by the Fund. Also, the prices of common stocks are sensitive to general movements in the stock market and a drop in the stock market may depress the price of common stocks to which the Fund has exposure. Common stock prices fluctuate for many reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant stock market, or when political or economic events affecting the issuers occur. In addition, common stock prices may be sensitive to rising interest rates, as the costs of capital rise and borrowing costs increase.

OPTIONS--GENERALLY
The Fund's principal options activity will consist of writing (selling) covered call options on common stocks held. Among other potential options strategies, the Fund may purchase put options on the S&P 500, the S&P MidCap 400, any other broad-based securities index deemed suitable for this purpose, and/or on individual stocks held in its portfolio to help protect against a decline in the value of its portfolio securities. An option on a security is a contract that gives the holder of the option, in return for a premium, the right to buy from (in the case of a call) or sell to (in the case of a put) the writer of the option the security underlying the option at a specified exercise or "strike" price. The writer of an option on a security has the obligation upon exercise of the option to deliver the underlying security upon payment of the exercise price or to pay the exercise price upon delivery of the underlying security. Certain options, known as "American style" options may be exercised at any time during the term of the option. Other options, known as "European style" options, may be exercised only on the expiration date of the option. Since listed options on individual stocks in the United States are generally American style options, the Adviser believes that substantially all of the single-stock options written or acquired by the Fund will be American style options. Exchange-traded options on stock indices are generally European style options.

The Fund will write call options only if they are "covered." A call option on a common stock or other security is covered if the Fund owns the security underlying the call or has an absolute and immediate right to acquire that security without additional cash consideration (or, if additional cash consideration is required, cash or other assets determined to be liquid by the Adviser (in accordance with procedures


15

INVESTMENT OBJECTIVES, POLICIES AND RISKS

established by the Board) in such amount are segregated by the Fund's custodian) upon conversion or exchange of other securities held by the Fund. A call option is also covered if the Fund holds a call on the same security as the call written where the exercise price of the call held is (i) equal to or less than the exercise price of the call written, or (ii) greater than the exercise price of the call written, provided the difference is maintained by the Fund in segregated assets determined to be liquid by the Adviser as described above.

If an option written by the Fund expires unexercised, the Fund realizes on the expiration date a capital gain equal to the premium received by the Fund at the time the option was written. If an option purchased by the Fund expires unexercised, the Fund realizes a capital loss equal to the premium paid. Prior to the earlier of exercise or expiration, an exchange-traded option may be closed out by an offsetting purchase or sale of an option of the same series (type, underlying security, exercise price, and expiration). There can be no assurance, however, that a closing purchase or sale transaction can be effected when the Fund desires. The Fund may sell put or call options it has previously purchased, which could result in a net gain or loss depending on whether the amount realized on the sale is more or less than the premium and other transaction costs paid on the put or call option when purchased. The Fund will realize a capital gain from a closing purchase transaction if the cost of the closing option is less than the premium received from writing the option, or, if it is more, the Fund will realize a capital loss. If the premium received from a closing sale transaction is more than the premium paid to purchase the option, the Fund will realize a capital gain or, if it is less, the Fund will realize a capital loss. In most cases, net gains from the Fund's option strategy will be short-term capital gains which, for federal income tax purposes, will constitute net investment company taxable income. See "Distributions--Federal income tax matters."

The principal factors affecting the market value of an option include supply and demand, interest rates, the current market price of the underlying security in relation to the exercise price of the option, the actual or perceived volatility of the underlying security, and the time remaining until the expiration date. The premium paid for an option purchased by the Fund is an asset of the Fund. The premium received for an option written by the Fund is recorded as an asset and equivalent liability. The Fund then adjusts over time the liability to the market value of the option. The value of an option purchased or written is marked to market daily and is valued at the closing price on the exchange on which it is traded or, if not traded on an exchange or no closing price is available, at the mean between the last bid and asked prices or otherwise at fair value as determined by the Board of the Fund.

The transaction costs of buying and selling options consist primarily of commissions (which are imposed in opening, closing, exercise and assignment transactions), but may also include margin and interest costs in particular transactions. The impact of transaction costs on the profitability of a transaction may often be greater for options transactions than for transactions in the underlying securities because these costs are often greater in relation to options premiums than in relation to the prices of underlying securities. Transaction costs may be especially significant in option strategies calling for multiple purchases and sales of options, such as spreads or straddles. Transaction costs may be different for transactions effected in foreign markets than for transactions effected in U.S. markets.

CALL OPTIONS AND COVERED CALL WRITING
The Fund does not intend to purchase call options as an investment. It will follow a principal options strategy known as "covered call option writing," which is a strategy designed to generate earnings and offset a portion of a market decline in the underlying common stock. The Fund will only write (sell) options on common stocks held in the Fund's portfolio. It may not sell "naked" call options, i.e., options representing more shares of the stock than are held in the portfolio.

The standard contract size for an exchange-listed single-stock option is 100 shares of the common stock. There are four items needed to identify a particular option contract: (1) the underlying security,


16

INVESTMENT OBJECTIVES, POLICIES AND RISKS

(2) the expiration month, (3) the exercise (or strike) price and (4) the type (call or put). For example, 20 ABC Corp. January 40 call options provide the right to purchase 2,000 shares of ABC Corp. common stock on or before January 22, 2005 at $40 per share. A call option whose strike price is above the current price of the underlying stock is called "out-of-the-money," a call option whose strike price is equal to the current price of the underlying stock is called "at-the-money" and a call option whose strike price is below the current price of the underlying stock is called "in-the-money."

The following is a conceptual example of the returns that may be achieved from a stock-plus-covered-call position, making the following assumptions: ABC common stock trades at $36.36 per share and ABC January 40 call options (10% out-of-the-money) trade at $1.82 per underlying share (5% option premium). This example is not meant to represent the performance of any actual common stock, option contract or the Fund itself.

The return over the period until option expiration earned by a holder of ABC stock who writes ABC January 40 call options and maintains the position until expiration will be as follows: (1) if the stock price declines 5%, the option will expire worthless and the holder will have a net return of zero (option premium offsets loss in stock); (2) if the stock price is flat, the option will again expire worthless and the holder will have a net return of 5% (option premium plus no gain or loss on stock); (3) if the stock price rises 10% (to the $40 strike price), the option will again expire with no value and the holder will have a net return of 15% (option premium plus 10% stock return); and (4) if the stock rises 20%, the exercise of the option would limit stock gain to 10% and total net return to 15%. If the stock price at exercise exceeds the strike price, returns from the position are capped at 15%.

As demonstrated in the example, writing covered call options on common stocks lowers the variability of potential returns and can enhance returns in three of four stock price performance scenarios (down, flat or moderately up). Only when the stock price at expiration exceeds the sum of the premium received and the option exercise price would the stock-plus-covered-call strategy be expected to provide lower returns than the underlying stock. The amount of downside protection afforded by the strategy in declining stock scenarios is limited, however, to the amount of option premium received. If the stock price declines in an amount greater than the option premium, the Fund will incur a net loss.

For conventional listed call options, the option's expiration date can be up to nine months from the date the call options are first listed for trading. Longer-term call options can have expiration dates up to three years from the date of listing. It is anticipated that many options that are written by the Fund against its stock holdings will be repurchased prior to the option's expiration date, generating a gain or loss in the options. Options that are not repurchased prior to expiration are subject to exercise by the option holder if the stock price at expiration is above the strike price.

Exchange-listed options contracts are originated and standardized by an independent entity called the Options Clearing Corporation (the "OCC"). Currently, listed options are available on over 2,300 stocks with new listings added periodically. The Fund will write (sell) call options that are generally issued, guaranteed and cleared by the OCC. Listed call options are traded on the American Stock Exchange, Chicago Board Options Exchange International Securities Exchange, New York Stock Exchange, Pacific Stock Exchange and Philadelphia Stock Exchange. The Adviser and Sub-Adviser believe that there exists sufficient trading volume in listed options to fulfill the Fund's option requirements to implement its strategies fully.

PUT OPTIONS
Put options are contracts that give the holder of the option, in return for a premium, the right to sell to the writer of the option the security/index underlying the option at a specified exercise price at any time during the term of the option. As discussed above, the Fund may in certain circumstances purchase put options on the S&P 500, S&P MidCap 400, any other broad-based securities index


17

INVESTMENT OBJECTIVES, POLICIES AND RISKS

deemed suitable for this purpose, and/or on individual stocks held in the portfolio to help protect against a decline in the value of the Fund's portfolio securities. The premiums paid to acquire put options will reduce amounts available for distribution from the Fund's options activity.

ADDITIONAL INVESTMENT PRACTICES

In addition to its primary investment policies, the Fund may engage in the following investment practices to a limited extent. Under normal market conditions, the Fund will invest at least 80% of its total assets in common stocks, including stocks of foreign issuers. The Fund may invest in the aggregate up to 20% of its total assets in all investments described below.

PREFERRED STOCKS
Preferred stock, like common stock, represents an equity ownership in an issuer. Generally, preferred stock has a priority of claim over common stock in dividend payments and upon liquidation of the issuer. Unlike common stock, preferred stock does not usually have voting rights. Preferred stock in some instances is convertible into common stock. Although they are equity securities, preferred stocks have certain characteristics of both debt and common stock. They are debt-like in that their promised income is contractually fixed. They are common stock-like in that they do not have rights to precipitate bankruptcy proceedings or collection activities in the event of missed payments. Furthermore, they have many of the key characteristics of equity due to their subordinated position in an issuer's capital structure and because their quality and value are heavily dependent on the profitability of the issuer rather than on any legal claims to specific assets or cash flows. The Fund will only invest in preferred stocks that are rated investment grade at the time of investment or, if unrated, determined by the Adviser to be of comparable quality. Standard & Poor's Ratings Group and Fitch Ratings consider securities rated BBB- and above to be investment grade and Moody's Investors Service, Inc. considers securities rated Baa3 and above to be investment grade.

FOREIGN SECURITIES
The Fund may invest up to 10% of its total assets in securities of issuers located in countries other than the United States. The Fund will not invest in issuers located in emerging market countries. The value of foreign securities is affected by changes in currency rates, foreign tax laws (including withholding tax), government policies (in this country or abroad), relations between nations and trading, settlement, custodial and other operational risks. In addition, the costs of investing abroad are generally higher than in the United States, and foreign securities markets may be less liquid, more volatile and less subject to governmental supervision than markets in the United States. Foreign investments also could be affected by other factors not present in the United States, including expropriation, armed conflict, confiscatory taxation, lack of uniform accounting and auditing standards, less publicly available financial and other information and potential difficulties in enforcing contractual obligations. As an alternative to holding foreign-traded securities, the Fund may invest in dollar-denominated securities of foreign companies that trade on U.S. exchanges or in the U.S. over-the-counter market (including depositary receipts, which evidence ownership in underlying foreign securities).

The Fund may invest in ADRs, EDRs and GDRs. ADRs, EDRs and GDRs are certificates evidencing ownership of shares of foreign issuers and are alternatives to purchasing directly the underlying foreign securities in their national markets and currencies. However, they continue to be subject to many of the risks associated with investing directly in foreign securities. These risks include foreign exchange risk as well as the political and economic risks of the underlying issuer's country. ADRs, EDRs and GDRs may be sponsored or unsponsored. Unsponsored receipts are established without the participation of the issuer. Unsponsored receipts may involve higher expenses, they may not pass- through voting or other shareholder rights, and they may be less liquid.


18

INVESTMENT OBJECTIVES, POLICIES AND RISKS

WARRANTS
The Fund may invest in equity and index warrants of domestic and international issuers. Equity warrants are securities that give the holder the right, but not the obligation, to subscribe for equity issues of the issuing company or a related company at a fixed price either on a certain date or during a set period. Changes in the value of a warrant do not necessarily correspond to changes in the value of its underlying security. The price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. Warrants do not entitle a holder to dividends or voting rights with respect to the underlying security and do not represent any rights in the assets of the issuing company. A warrant ceases to have value if it is not exercised prior to its expiration date. These factors can make warrants more speculative than other types of investments. The sale of a warrant results in a long- or short-term capital gain or loss depending on the period for which a warrant is held.

CONVERTIBLE SECURITIES AND BONDS WITH WARRANTS ATTACHED
The Fund may invest in preferred stocks and fixed-income obligations that are convertible into common stocks of domestic and foreign issuers, and bonds issued as a unit with warrants. Convertible securities in which the Fund may invest, comprised of both convertible debt and convertible preferred stock, may be converted at either a stated price or at a stated rate into underlying shares of common stock. Because of this feature, convertible securities generally enable an investor to benefit from increases in the market price of the underlying common stock. Convertible securities often provide higher yields than the underlying equity securities, but generally offer lower yields than non-convertible securities of similar quality. The value of convertible securities fluctuates in relation to changes in interest rates like bonds, and, in addition, fluctuates in relation to the underlying common stock.

SHORT SALES
The Fund may sell a security short if it owns at least an equal amount of the security sold short or another security convertible or exchangeable for an equal amount of the security sold short without payment of further compensation (a short sale against-the-box). In a short sale against-the-box, the short seller is exposed to the risk of being forced to deliver stock that it holds to close the position if the borrowed stock is called in by the lender, which would cause gain or loss to be recognized on the delivered stock. The Fund expects normally to close its short sales against-the-box by delivering newly acquired stock.

The ability to use short sales against-the-box, certain equity swaps and certain equity collar strategies as a tax-efficient management technique with respect to holdings of appreciated securities is limited to circumstances in which the hedging transaction is closed out not later than thirty days after the end of the Fund's taxable year in which the transaction was initiated, and the underlying appreciated securities position is held unhedged for at least the next sixty days after the hedging transaction is closed. Not meeting these requirements would trigger the recognition of gain on the underlying appreciated securities position under the federal tax laws applicable to constructive sales.

TEMPORARY INVESTMENTS
Cash equivalents are highly liquid, short-term securities such as commercial paper, time deposits, certificates of deposit, short-term notes and short-term U.S. government obligations. During unusual market circumstances, the Fund may temporarily invest a substantial portion of its assets in cash or cash equivalents, which may be inconsistent with the Fund's investment objectives. In moving to a substantial temporary investments position and in transitioning from such a position back into full conformity with the Fund's normal investment objectives and policies, the Fund may incur transaction costs that would not be incurred if the Fund had remained fully invested in accordance with such normal policies. The transition to and back from a substantial temporary investments position may also result in the Fund having to sell common stocks and/or close out options positions and then latter


19

INVESTMENT OBJECTIVES, POLICIES AND RISKS

purchase common stocks and open new options positions in circumstances that might not otherwise be optimal.

WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS
Securities may be purchased on a "forward commitment" or "when-issued" basis (meaning securities are purchased or sold with payment and delivery taking place in the future) in order to secure what is considered to be an advantageous price and yield at the time of entering into the transaction. However, the return on a comparable security when the transaction is consummated may vary from the return on the security at the time that the forward commitment or when-issued transaction was made. From the time of entering into the transaction until delivery and payment is made at a later date, the securities that are the subject of the transaction are subject to market fluctuations. In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous. Forward commitment or when-issued transactions may occur a month or more before delivery is due. However, no payment or delivery is made until payment is received or delivery is made from the other party to the transaction. Forward commitment or when-issued transactions will not be entered into for the purpose of investment leverage.

ILLIQUID SECURITIES
The Fund may invest up to 15% of its total assets in securities for which there is no readily available trading market or are otherwise illiquid. Illiquid securities include securities legally restricted as to resale, such as commercial paper issued pursuant to Section 4(2) of the Securities Act of 1933, as amended, and securities eligible for resale pursuant to Rule 144A thereunder.
Section 4(2) and Rule 144A securities may, however, be treated as liquid by the Adviser pursuant to procedures adopted by the Board, which require consideration of factors such as trading activity, availability of market quotations and number of dealers willing to purchase the security. If the Fund invests in Rule 144A securities, the level of portfolio illiquidity may be increased to the extent that eligible buyers become uninterested in purchasing such securities.

It may be difficult to sell illiquid securities at a price representing their fair value until such time as such securities may be sold publicly. Where registration is required, a considerable period may elapse between a decision to sell the securities and the time when it would be permitted to sell. Thus, the Fund may not be able to obtain as favorable a price as that prevailing at the time of the decision to sell. The Fund may also acquire securities through private placements under which it may agree to contractual restrictions on the resale of such securities. Such restrictions might prevent their sale at a time when such sale would otherwise be desirable.

OTHER DERIVATIVE INSTRUMENTS
In addition to the intended strategy of selling covered call options and purchasing put options, the Fund may invest up to 20% of its total assets in derivative instruments (which are instruments that derive their value from another instrument, security or index) acquired for hedging, risk management and investment purposes (to gain exposure to securities, securities markets, markets indices and/or currencies consistent with its investment objectives and policies), provided that no more than 10% of the Fund's total assets may be invested in such derivative instruments acquired for non-hedging purposes. These strategies may be executed through the use of derivative contracts in the United States or abroad. In the course of pursuing these investment strategies, the Fund may purchase and sell equity and fixed-income indices and other instruments, purchase and sell futures contracts and options thereon, and enter into various transactions such as swaps, caps, floors or collars. In addition, derivatives may also include new techniques, instruments or strategies that are permitted as regulatory changes occur. Derivative instruments may be used by the Fund to enhance returns or as a substitute for the purchase or sale of securities.


20

INVESTMENT OBJECTIVES, POLICIES AND RISKS

SWAPS
Swap contracts may be purchased or sold to hedge against fluctuations in securities prices, interest rates or market conditions, to mitigate non-payment or default risk, or to gain exposure to particular securities, baskets of securities, indices or currencies. In a standard "swap" transaction, two parties agree to exchange the returns (or differentials in rates of return) to be exchanged or "swapped" between the parties, which returns are calculated with respect to a "notional amount," i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, or in a particular security, "basket" of securities or index. The Fund will enter into swaps only on a net basis, i.e., the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. If the other party to a swap defaults, the Fund's risk of loss consists of the net amount of payments that the Fund is contractually entitled to receive. The net amount of the excess, if any, of the Fund's obligations over its entitlements will be maintained in a segregated account by the Fund's custodian. The Fund will not enter into any swap unless the claims-paying ability of the other party thereto is considered to be investment grade by the Adviser. If there is a default by the other party to such a transaction, the Fund will have contractual remedies pursuant to the agreements related to the transaction. Swaps are traded in the over-the-counter market. The use of swaps is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Adviser is incorrect in its forecasts of market values, interest rates and other applicable factors, the investment performance of the Fund would be unfavorably affected.

Total return swaps. Total return swaps are contracts in which one party agrees to make payments of the total return from the underlying asset(s), which may include securities, baskets of securities, or securities indices during the specified period, in return for payments equal to a fixed or floating rate of interest or the total return from other underlying asset(s).

Interest rate swaps. Interest rate swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of fixed rate payments for floating rate payments).

FUTURES AND OPTIONS ON FUTURES
The Fund may purchase and sell various kinds of financial futures contracts and options thereon to seek to hedge against changes in stock prices or interest rates, for other risk management purposes or to gain exposure to certain securities, indices and currencies. Futures contracts may be based on various securities indices and securities. Such transactions involve a risk of loss or depreciation due to adverse changes in securities prices, which may exceed the Fund's initial investment in these contracts. The Fund will only purchase or sell futures contracts or related options in compliance with the rules of the Commodity Futures Trading Commission. These transactions involve transaction costs. Sales of futures contracts and related options generally result in realization of short-term or long-term capital gain depending on the period for which the investment is held. To the extent that any futures contract or options on futures contract held by the Fund is a "Section 1256 contract" under the Internal Revenue Code of 1986, as amended (the "Code"), the contract will be marked-to-market annually and any gain or loss will be treated as 60% long-term and 40% short-term, regardless of the holding period for such contract.

SECURITIES LENDING
The Fund may seek to earn income by lending portfolio securities to broker-dealers or other institutional borrowers. As with other extensions of credit, there are risks of delay in recovery or even loss of rights in the securities loaned if the borrower of the securities fails financially. Loans will be made only to organizations whose credit quality or claims paying ability is considered by the Adviser to be at least investment grade and when the expected returns, net of administrative expenses and any finders' fees, justifies the attendant risk. Securities loans currently are required to be secured


21

INVESTMENT OBJECTIVES, POLICIES AND RISKS

continuously by collateral in cash, cash equivalents (such as money market instruments) or other liquid securities held by the custodian and maintained in an amount at least equal to the market value of the securities loaned. The financial condition of the borrower will be monitored by the Adviser on an ongoing basis. The Fund will not lend portfolio securities subject to a written covered call contract.

BORROWINGS
The Fund may borrow money to the extent permitted under the 1940 Act as interpreted, modified or otherwise permitted by the regulatory authority having jurisdiction. Although there is no current intention to do so, the Fund may in the future from time to time borrow money to add leverage to the portfolio. The Fund may also borrow money for temporary administrative purposes.

REVERSE REPURCHASE AGREEMENTS
The Fund may enter into reverse repurchase agreements. Under a reverse repurchase agreement, the Fund temporarily transfers possession of a portfolio instrument to another party, such as a bank or broker-dealer, in return for cash. At the same time, the Fund agrees to repurchase the instrument at an agreed upon time (normally within seven days) and price, which reflects an interest payment. The Fund may enter into such agreements when it is able to invest the cash acquired at a rate higher than the cost of the agreement, which would increase earned income. Income realized on reverse repurchase agreements will be taxable as ordinary income.

When the Fund enters into a reverse repurchase agreement, any fluctuations in the market value of either the securities transferred to another party or the securities in which the proceeds may be invested would affect the market value of the Fund's assets. As a result, such transactions may increase fluctuations in the market value of the Fund's assets. While there is a risk that large fluctuations in the market value of the Fund's assets could affect net asset value, this risk is not significantly increased by entering into reverse repurchase agreements, in the opinion of the Adviser. Because reverse repurchase agreements may be considered to be the practical equivalent of borrowing funds, they constitute a form of leverage and may be subject to leverage risks. Such agreements will be treated as subject to investment restrictions regarding "borrowings." If the Fund reinvests the proceeds of a reverse repurchase agreement at a rate lower than the cost of the agreement, entering into the agreement will lower the Fund's yield.

PORTFOLIO TURNOVER
The Fund will buy and sell securities to seek to accomplish it investment objectives. Portfolio turnover generally involves some expense to the Fund, including brokerage commissions and other transaction costs on the sale of securities and reinvestment in other securities. Higher portfolio turnover may decrease the after-tax return to Common Shareholders to the extent it results in a decrease of the long-term capital gains portion of distributions to Common Shareholders. Although the Fund cannot accurately predict its portfolio turnover rate, under normal market conditions it expects to maintain relatively low core turnover of its stock portfolio, not considering purchases and sales of stock and options in connection with the Fund's options program. On an overall basis, the Fund's annual turnover rate may exceed 100%. A high turnover rate (100% or more) necessarily involves greater trading costs to the Fund and may result in greater realization of taxable capital gains.

RISK CONSIDERATIONS

NO OPERATING HISTORY
The Fund is a closed-end investment company with no history of operations and is designed for long-term investors and not as a trading vehicle.


22

INVESTMENT OBJECTIVES, POLICIES AND RISKS

INVESTMENT AND MARKET RISK
An investment in Common Shares is subject to investment risk, including the possible loss of the entire principal amount invested. An investment in Common Shares represents an indirect investment in the securities owned by the Fund, which are generally traded on a securities exchange or in the over-the-counter markets. The value of these securities, like other market investments, may move up or down, sometimes rapidly and unpredictably. In addition, by writing (selling) call options on the equity securities held in the Fund's portfolio, the capital appreciation potential of such securities will be limited to the difference between the exercise price of the call options written and the purchase price of the equity security underlying such options. The Common Shares at any point in time may be worth less than the original investment, even after taking into account any reinvestment of distributions.

ISSUER RISK
The value of securities held by the Fund may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods and services.

EQUITY RISK
At least 80% of the Fund's total assets will be invested in common stocks and therefore a principal risk of investing in the Fund is equity risk. Equity risk is the risk that securities held by the Fund will fall due to general market or economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, and the particular circumstances and performance of particular companies whose securities the Fund holds. Although common stocks have historically generated higher average returns than fixed-income securities over the long term, common stocks also have experienced significantly more volatility in returns. An adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common equity securities in which the Fund will invest are structurally subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. Finally, common stock prices may be sensitive to rising interest rates, as the costs of capital rise and borrowing costs increase.

RISKS ASSOCIATED WITH OPTIONS ON SECURITIES
There are numerous risks associated with transactions in options on securities. A decision as to whether, when and how to use options involves the exercise of skill and judgment, and even a well-conceived transaction may be unsuccessful to some degree because of market behavior or unexpected events. As the writer of a covered call option, the Fund forgoes, during the option's life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the option premium received and the exercise price of the call, but has retained the risk of loss, minus the option premium received, should the price of the underlying security decline. The writer of an option has no control over when during the exercise period of the option it may be required to fulfill its obligation as a writer of the option. Once an option writer has received an exercise notice, it cannot effect a closing purchase transaction in order to terminate its obligation under the option and must deliver the underlying security at the exercise price. Thus, the use of options may require the Fund to sell portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the Fund can realize on an investment, or may cause the Fund to hold a security that it might otherwise sell.


23

INVESTMENT OBJECTIVES, POLICIES AND RISKS

The value of options may be adversely affected if the market for such options becomes less liquid or smaller. There can be no assurance that a liquid market will exist when the Fund seeks to close out an option position either, in the case of a call option written, by buying the option, or, in the case of a purchased put option, by selling the option. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both;
(iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or the OCC may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled to discontinue the trading of options (or a particular class or series of options) at some future date. If trading were discontinued, the secondary market on that exchange (or in that class or series of options) would cease to exist. However, outstanding options on that exchange that had been issued by the OCC as a result of trades on that exchange would continue to be exercisable in accordance with their terms. The Fund's ability to terminate over-the-counter options will be more limited than with exchange-traded options and may involve the risk that broker-dealers participating in such transactions will not fulfill their obligations. If the Fund were unable to close out a covered call option that it had written on a security, it would not be able to sell the underlying security unless the option expired without exercise.

The hours of trading for options may not conform to the hours during which the underlying securities are traded. To the extent that the options markets close before the markets for the underlying securities, significant price and rate movements can take place in the underlying markets that would not be reflected concurrently in the options markets. Call options are marked to market daily and their value will be affected by changes in the value of and dividend rates of the underlying common stocks, changes in interest rates, changes in the actual or perceived volatility of the stock market and the underlying common stocks and the remaining time to the options' expiration. Additionally, the exercise price of an option may be adjusted downward before the option's expiration as a result of the occurrence of certain corporate events affecting the underlying equity security, such as extraordinary dividends, stock splits, merger or other extraordinary distributions or events. A reduction in the exercise price of an option would reduce the Fund's capital appreciation potential on the underlying security.

If the Fund purchases put options for hedging or risk management purposes, the Fund will be subject to the following additional risks. A put option acquired by the Fund and not sold prior to expiration will expire worthless if the price of the stock or index at expiration exceeds the exercise price of the option, thereby causing the Fund to lose its entire investment in the option. If restrictions on exercise were imposed, the Fund might be unable to exercise an option it had purchased. If the Fund were unable to close out an option that it had purchased, it would have to exercise the option in order to realize any profit or the option may expire worthless. Stock market indices on which the Fund may purchase options positions will not mirror the Fund's actual portfolio holdings. The effectiveness of index put options as hedges against declines in the Fund's stock portfolio will be limited to the extent that the performance of the underlying index does not correlate with that of the Fund's holdings.

LIMITATION ON OPTION WRITING
The number of call options the Fund can write is limited by the number of shares of common stock the Fund holds, and further limited by the fact that listed call options on individual common stocks generally trade in units representing 100 shares of the underlying stock. Furthermore, the Fund's options transactions will be subject to limitations established by each of the exchanges, boards of trade or other trading facilities on which such options are traded. These limitations govern the maximum number of options in each class which may be written or purchased by a single investor or group of


24

INVESTMENT OBJECTIVES, POLICIES AND RISKS

investors acting in concert, regardless of whether the options are written or purchased on the same or different exchanges, boards of trade or other trading facilities or are held or written in one or more accounts or through one or more brokers. Thus, the number of options which the Fund may write or purchase may be affected by options written or purchased by other investment advisory clients of the Adviser or Sub-Adviser. An exchange, board of trade or other trading facility may order the liquidation of positions found to be in excess of these limits, and may impose certain other sanctions. The Fund will not write "naked" or uncovered call options.

RISKS OF MID-CAP COMPANIES
The Fund may invest substantially in companies whose market capitalization is considered middle sized or "mid-cap." Mid-cap companies often are newer or less established companies than larger companies. Investments in mid-cap companies carry additional risks because earnings of these companies tend to be less predictable; they often have limited product lines, markets, distribution channels or financial resources; and the management of such companies may be dependent upon one or a few key people. The market movements of equity securities of mid-cap companies may be more abrupt or erratic than the market movements of equity securities of larger, more established companies or the stock market in general. Historically, mid-cap companies have sometimes gone through extended periods when they did not perform as well as larger companies. In addition, equity securities of mid-cap companies generally are less liquid than those of larger companies. This means that the Fund could have greater difficulty selling such securities at the time and price that the Fund would like.

RISKS OF GROWTH STOCK INVESTING
The Fund expects to invest substantially in stocks with "growth" characteristics. Growth stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks. Growth stocks tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, growth stocks tend to be sensitive to changes in their earnings and more volatile than other types of stocks.

DISTRIBUTION RISK
The monthly distributions Common Shareholders receive from the Fund will be based primarily on the level of net option premiums and the dividends received by the Fund. Net option premiums and dividend payments the Fund receives in respect of its portfolio securities can vary widely over the short- and long-term. If stock prices or stock price volatility declines, the level of premiums from options writing and the amounts available for distribution from options activity will likely decrease as well. Payments to purchase put options and to close written call options will reduce amounts available for distribution from call option premiums received and proceeds of closing put options. Dividends on common stocks are not fixed but are declared at the discretion of the issuer's board of directors. There is no guarantee that the issuers of common stocks in which the Fund invests will declare dividends in the future or that if declared they will remain at current levels or increase over time. Dividends on any preferred stocks in which the Fund may invest are not guaranteed and certain issues of preferred stock held by the Fund may be called by the issuer.

FOREIGN SECURITY RISK
The value of foreign securities is affected by changes in currency rates, foreign tax laws (including withholding tax), government policies (in this country or abroad), relations between nations and trading, settlement, custodial and other operational risks. In addition, the costs of investing abroad are generally higher than in the United States, and foreign securities markets may be less liquid, more volatile and less subject to governmental supervision than markets in the United States. Foreign investments also could be affected by other factors not present in the United States, including expropriation, armed conflict, confiscatory taxation, lack of uniform accounting and auditing


25

INVESTMENT OBJECTIVES, POLICIES AND RISKS

standards, less publicly available financial and other information and potential difficulties in enforcing contractual obligations. As an alternative to holding foreign-traded securities, the Fund may invest in dollar-denominated securities of foreign companies that trade on U.S. exchanges or in the U.S. over-the-counter market (including depositary receipts, which evidence ownership in underlying foreign securities). Since the Fund may invest in securities denominated or quoted in currencies other than the U.S. dollar, the Fund will be affected by changes in foreign currency exchange rates (and exchange control regulations) which affect the value of investments in the Fund and the accrued income and appreciation or depreciation of the investments in U.S. dollars. Changes in foreign currency exchange rates relative to the U.S. dollar will affect the U.S. dollar value of the Fund's assets denominated in that currency and the Fund's return on such assets as well as any temporary uninvested reserves in bank deposits in foreign currencies. In addition, the Fund will incur costs in connection with conversions between various currencies.

INTEREST RATE RISK
The level of premiums from call options writing and the amounts available for distribution from the Fund's options activity may decrease in declining interest rate environments. Any preferred stocks paying fixed dividend rates in which the Fund invests, will likely change in value as market interest rates change. When interest rates rise, the market value of such securities generally will fall. To the extent that the Fund invests in preferred stocks, the net asset value and price of the Common Shares may decline if market interest rates rise. Interest rates are currently low relative to historic levels. During periods of declining interest rates, an issuer of preferred stock may exercise its option to redeem securities prior to maturity, forcing the Fund to reinvest in lower yielding securities. This is known as call risk. During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected payments. This may lock in a below market yield, increase the security's duration, and reduce the value of the security. This is known as extension risk. The value of the Fund's common stock investments may also be influenced by changes in interest rates.

SECTOR RISK
The Fund may invest a significant portion of its assets in securities of issuers in any single industry or sector of the economy (a broad based economic segment that may include many distinct industries) if companies in that industry or sector meet the Fund's investment criteria. If the Fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries or sectors of the economy. A "sector" is a broader economic segment that may include many different industries. This may make the Fund more susceptible to adverse economic, political, or regulatory occurrences affecting these sectors. As the percentage of the Fund's assets invested in a particular sector increases, so does the potential for fluctuation in the net asset value of Common Shares. The Fund may not invest 25% or more of its total assets in the securities of issuers in any single industry or group of industries.

DERIVATIVES RISK
In addition to writing covered call options, the risks of which are described above, the Fund may invest up to 20% of its total assets in other derivative investments acquired for hedging, risk management and investment purposes. Derivative transactions including options on securities and securities indices and other transactions in which the Fund may engage (such as futures contracts and options thereon, swaps and short sales) may subject the Fund to increased risk of principal loss due to unexpected movements in stock prices, changes in stock volatility levels and interest rates, and imperfect correlations between the Fund's securities holdings and indices upon which derivative transactions are based. The Fund also will be subject to credit risk with respect to the counterparties to any over-the-counter derivatives contracts purchased by the Fund. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative


26

INVESTMENT OBJECTIVES, POLICIES AND RISKS

contract in a bankruptcy or other reorganization proceeding. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances.

LIQUIDITY RISK
The Fund may invest up to 15% of its total assets in securities for which there is no readily available trading market or which are otherwise illiquid. The Fund may not be able readily to dispose of such securities at prices that approximate those at which the Fund could sell such securities if they were more widely traded and, as a result of such illiquidity, the Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. In addition, the limited liquidity could affect the market price of the securities, thereby adversely affecting the Fund's net asset value.

INFLATION RISK
Inflation risk is the risk that the purchasing power of assets or income from investment will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Shares and distributions thereon can decline.

MARKET PRICE OF COMMON SHARES
The shares of closed-end management investment companies often trade at a discount from their net asset value, and the Fund's Common Shares may likewise trade at a discount from net asset value. The trading price of the Fund's Common Shares may be less than the public offering price. The returns earned by Common Shareholders who purchased their Common Shares in this offering and sell their Common Shares below net asset value will be reduced.

FINANCIAL LEVERAGE
Although the Fund has no current intention to do so, the Fund is authorized to utilize leverage through the issuance of preferred shares and/or borrowings, including the issuance of debt securities. In the event that the Fund determines in the future to utilize investment leverage, there can be no assurance that such a leveraging strategy will be successful during any period in which it is employed. Leverage creates risks for Common Shareholders, including the likelihood of greater volatility of net asset value and market price of the Common Shares and the risk that fluctuations in distribution rates on any preferred shares or fluctuations in borrowing costs may affect the return to Common Shareholders. To the extent the income derived from securities purchased with proceeds received from leverage exceeds the cost of leverage, the Fund's distributions will be greater than if leverage had not been used. Conversely, if the income from the securities purchased with such proceeds is not sufficient to cover the cost of leverage, the amount available for distribution to Common Shareholders will be less than if leverage had not been used. In the latter case, Eaton Vance, in its best judgment, may nevertheless determine to maintain the Fund's leveraged position if it deems such action to be appropriate. The costs of an offering of preferred shares and/or a borrowing program would be borne by Common Shareholders and consequently would result in a reduction of the net asset value of Common Shares. In addition, the fee paid to Eaton Vance will be calculated on the basis of the Fund's average daily gross assets, including proceeds from the issuance of preferred shares and/or borrowings, so the fees will be higher when leverage is utilized. In this regard, holders of preferred shares do not bear the investment advisory fee. Rather, Common Shareholders bear the portion of the investment advisory fee attributable to the assets purchased with the proceeds of the preferred shares offering.

MANAGEMENT RISK
The Fund is subject to management risk because it is an actively managed portfolio. Eaton Vance, Rampart and the individual portfolio managers will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the


27

INVESTMENT OBJECTIVES, POLICIES AND RISKS

desired results. The Fund may be subject to additional management risk because the Fund's options program will require effective coordination between the Adviser and the Sub-Adviser.

MARKET DISRUPTION
The terrorist attacks in the United States on September 11, 2001 had a disruptive effect on the securities markets. These terrorist attacks and related events, including the war in Iraq, its aftermath, and continuing occupation of Iraq by coalition forces, have raised short-term market risk and may have adverse long-term effects on U.S. and world economies and markets. A similar disruption of the financial markets could impact trading in common stocks and stock options, interest rates, credit risk, inflation and other factors relating to the Common Shares. The Fund cannot predict the effects of similar events in the future on the U.S. economy and securities markets.

ANTI-TAKEOVER PROVISIONS
The Fund's Agreement and Declaration of Trust includes provisions that could have the effect of limiting the ability of other persons or entities to acquire control of the Fund or to change the composition of its Board. See "Description of capital structure--Anti-takeover provisions in the Declaration of Trust."

Management of the Fund

BOARD OF TRUSTEES

The management of the Fund, including general supervision of the duties performed by the Adviser under the Advisory Agreement (as defined below) and the Sub-Adviser under the Sub-Advisory Agreement (as defined below), is the responsibility of the Fund's Board under the laws of The Commonwealth of Massachusetts and the 1940 Act.

THE ADVISER

Eaton Vance acts as the Fund's investment adviser under an Investment Advisory Agreement (the "Advisory Agreement"). The Adviser's principal office is located at The Eaton Vance Building, 255 State Street, Boston, MA 02109. Eaton Vance, its affiliates and predecessor companies have been managing assets of individuals and institutions since 1924 and of investment funds since 1931. Eaton Vance (or its affiliates) currently serves as the investment adviser to investment funds and various individual and institutional clients with combined assets under management of approximately $89.4 billion as of July 31, 2004, including approximately $33.0 billion in equity fund assets. Eaton Vance is a direct, wholly-owned subsidiary of Eaton Vance Corp., a publicly-held holding company, which through its subsidiaries and affiliates engages primarily in investment management, administration and marketing activities.

Under the general supervision of the Fund's Board, the Adviser will carry out the investment and reinvestment of the assets of the Fund, will furnish continuously an investment program with respect to the Fund, will determine which securities should be purchased, sold or exchanged, and will implement such determinations. The Adviser will furnish to the Fund investment advice and office facilities, equipment and personnel for servicing the investments of the Fund. The Adviser will compensate all Trustees and officers of the Fund who are members of the Adviser's organization and who render investment services to the Fund, and will also compensate all other Adviser personnel who provide research and investment services to the Fund. In return for these services, facilities and payments, the Fund has agreed to pay the Adviser as compensation under the Advisory Agreement an annual fee in the amount of 1.00% of the average daily gross assets of the Fund. Gross assets of the Fund means total assets of the Fund, including any form of investment leverage that the Fund may in the future determine to utilize, minus all accrued expenses incurred in the normal course of operations,


28

MANAGEMENT OF THE FUND

but not excluding any liabilities or obligations attributable to any future investment leverage obtained through (i) indebtedness of any type (including, without limitation, borrowing through a credit facility/commercial paper program or the issuance debt securities), (ii) the issuance of preferred shares or other similar preference securities, (iii) the reinvestment of collateral received for securities loaned in accordance with the Fund's investment objectives and policies, and/or (iv) any other means. During any future periods in which the Fund is using leverage, the fees paid to Eaton Vance for investment advisory services will be higher than if the Fund did not use leverage because the fees paid will be calculated on the basis of the Fund's gross assets, including proceeds from any borrowings and from the issuance of preferred shares.

Walter A. Row, Lewis R. Piantedosi and other Eaton Vance investment professionals comprise the investment team responsible for the overall management of the Fund's investments. Mr. Row and Mr. Piantedosi are the portfolio managers responsible for the day-to-day management of the Fund's investment portfolio.

Mr. Row is a Vice President and the Director of Equity Research at Eaton Vance. He is a member of Eaton Vance's Equity Strategy Committee, manages another Eaton Vance registered investment company and has been an equity analyst and member of Eaton's Vance's equity research team since 1996.

Mr. Piantedosi is a Vice President of Eaton Vance. He is a member of Eaton Vance's Equity Strategy Committee and co-manager of another Eaton Vance registered investment company. He first joined Eaton Vance's equity group in 1996.

THE SUB-ADVISER

Eaton Vance has engaged Rampart Investment Management Company to serve as a sub-adviser to the Fund to provide advice on and execution of the Fund's options strategy. The Sub-Adviser's principal office is located at One International Place, Boston, MA 02110. Rampart Investment Management Company, Inc. was founded in 1983 by its current principals Ronald M. Egalka and David R. Fraley. The Sub-Adviser provides customized investment management services within its core competency in options program management to a spectrum of institutional and high net worth clients. Since its inception, the Sub-Adviser has continuously expanded its computer modeling and analytical capabilities and created tools to identify and capitalize on opportunities in the options markets. Rampart managed approximately $1.0 billion in assets as of August 31, 2004.

Mr. Egalka and Mr. Fraley are responsible for the development and implementation of Rampart's options strategy utilized in managing the Fund.

Mr. Egalka is President and CEO of Rampart. He is also President of Rampart Securities, Inc., an affiliate of the Sub-Adviser and a NASD member broker/dealer. Mr. Egalka oversees the development and implementation of investment strategies and tactics for Rampart. He has created a variety of analytical and management tools including the Rampart Time Premium Index, published each week in Barron's, the Rampart Volatility Indexes and the Rampart Options Management System (ROMS), the technological platform from which Rampart's portfolio managers deliver the company's equity options management expertise.

As one of the early pioneers in personal computers and quantitative hedging, Mr. Egalka was a founding director of the Boston Computer Society, charter member of the National Options and Futures Society, a founder of the Boston Options Society and a guest lecturer on derivatives at Boston College. From 1973 to 1981, he was a portfolio manager and senior research officer at The Boston Company, specializing in hedged equity strategies. In 1981, Mr. Egalka joined Colonial Management Associates where he developed and managed a corporate cash management mutual fund and many of the company's portfolio hedging capabilities.


29

MANAGEMENT OF THE FUND

A long time proponent of hedged equities as an asset class, Mr. Egalka has focused on helping create an industry benchmark for options programs. The creation and subsequent launch of the CBOE/S&P 500 BuyWrite Index (BXM) in 2002 was the realization of that objective. In 2003, the CBOE announced that it had licensed the BXM to Rampart as the strategic basis for new options investment vehicles.

Mr. Fraley is Managing Director/Manager of Marketing and Client Service at Rampart. He manages Rampart's new product development and customization of existing investment strategies for specific client needs. Prior to joining Rampart, Mr. Fraley served in a number of management roles with Merrill Lynch Capital Markets in Boston from 1975 through 1983.

Under the terms of the Sub-Advisory Agreement (the "Sub-Advisory Agreement") between Eaton Vance and the Sub-Adviser, Eaton Vance (and not the Fund) will pay the Sub-Adviser a fee at a annual rate equal to 0.235% of the average daily gross assets of the Fund. Pursuant to the terms of the Advisory Agreement, Eaton Vance, upon approval by the Board, may terminate the Sub-Advisory Agreement and Eaton Vance may assume full responsibility for the services provided by the Sub-Adviser without the need for approval by shareholders of the Fund. Rampart Investment Management Company has agreed to reimburse Eaton Vance in certain circumstances for a portion of the payments that Eaton Vance makes to the Shareholder Servicing Agent under the Shareholder Servicing Agreement. See "Shareholder Servicing Agent, custodian and transfer agent."

The Fund, the Adviser and the Sub-Adviser have adopted codes of ethics relating to personal securities transactions (the "Codes of Ethics"). The Codes of Ethics permit Adviser and Sub-Adviser personnel to invest in securities (including securities that may be purchased or held by the Fund) for their own accounts, subject to certain pre-clearance, reporting and other restrictions and procedures contained in such Codes of Ethics.

THE ADMINISTRATOR

Eaton Vance serves as administrator of the Fund, but currently receives no compensation for providing administrative services to the Fund. Under an Administration Agreement with the Fund (the "Administration Agreement"), Eaton Vance is responsible for managing the business affairs of the Fund, subject to the supervision of the Fund's Board. Eaton Vance will furnish to the Fund all office facilities, equipment and personnel for administering the affairs of the Fund. Eaton Vance's administrative services include recordkeeping, preparation and filing of documents required to comply with federal and state securities laws, supervising the activities of the Fund's custodian and transfer agent, providing assistance in connection with the Board and shareholders' meetings, providing service in connection with any repurchase offers and other administrative services necessary to conduct the Fund's business.

Distributions

Commencing with the Fund's first distribution, the Fund intends to make regular monthly distributions to Common Shareholders based upon the Fund's projected annual cash available from option premiums and dividends. For distribution purposes, "cash available from option premiums and dividends" will consist of the total proceeds of options sales plus dividends and interest received, less amounts paid to purchase options and Fund expenses. The Fund's distribution rate may be adjusted from time-to-time. The Board may modify this distribution policy at any time without obtaining the approval of Common Shareholders. The initial distribution is expected to be declared approximately 45-60 days and paid approximately 60-90 days after the completion of this offering, depending on market conditions.


30

DISTRIBUTIONS

The Fund's annual cash available from options premiums and dividends will likely differ from annual net investment income. The investment income of the Fund will consist of all dividend and interest income accrued on portfolio investments, short-term capital gain (including, short-term gains on terminated option positions and gains on the sale of portfolio investments held for one year or less) in excess of long-term capital loss and income from certain hedging transactions, less all expenses of the Fund. Expenses of the Fund will be accrued each day. Over time, all of the Fund's investment company taxable income will be distributed. In addition, at least annually, the Fund intends to distribute any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss).

To the extent that that Fund's net investment income and net capital gain (which is the excess of net long-term capital gain over net short-capital loss) for any year exceed the total monthly income distributions paid during the year, the Fund will make a special distribution at or near year-end of such excess amount as may be required. If the Fund's total monthly distributions in any year exceed the amount of its net investment income and net capital gain for any year, any such excess would be characterized as a return of capital. Under the 1940 Act, for any distribution that includes amounts from sources other than net income, the Fund is required to provide Common Shareholders a written statement regarding the components of such distribution.

If, for any calendar year, as discussed above, the total distributions made under the Fund's policy exceed the Fund's net investment taxable income and net capital gain, the excess will be treated as a tax-free return of capital to each Common Shareholder (up to the amount of the Common Shareholder's basis in his or her Common Shares) and thereafter as gain from the sale of Common Shares. The amount treated as a tax-free return of capital will reduce the Common Shareholder's adjusted basis in his or her Common Shares, thereby increasing his or her potential gain or reducing his or her potential loss on the subsequent sale of his or her Common Shares. To the extent the Fund's distribution policy results in distributions in excess of its net investment taxable income and net capital gain, such distributions will decrease its total assets and increase its expense ratio to a greater extent than would have been the case if distributions were limited to these amounts. Distributions in any year may or may not include a substantial return of capital component.

To permit the Fund to maintain more stable distributions, distribution rates will be based on projected annual cash available from options premiums and dividends. As a result, the distributions paid by the Fund for any particular month may be more or less than the amount of cash available from options premiums and dividends for that month. In such circumstances, the Fund may have to sell a portion of its investment portfolio to make a distribution at a time when independent investment judgment might not dictate such action. Undistributed net investment income is included in the Common Shares' net asset value, and, correspondingly, distributions from net investment income will reduce the Common Shares' net asset value.

Common Shareholders may elect automatically to reinvest some or all of their distributions in additional Common Shares under the Fund's dividend reinvestment plan. See "Dividend reinvestment plan."

The Fund has applied for an order from the SEC granting exemption from Section 19(b) of the Investment Company Act, and Rule 19b-1 thereunder to permit the Fund to include realized long-term capital gains as a part of its regular distributions to Common Shareholders more frequently than would otherwise be permitted by the Investment Company Act. The Fund will not pursue this distribution policy until it receives such an exemptive order. There is no guarantee that the SEC will grant such exemptive relief. However, if the Fund fails to receive the requested relief and the Fund is unable to include realized capital gains in regular distributions more frequently than would otherwise


31

DISTRIBUTIONS

be permitted by the Investment Company Act, the Adviser does not believe that the distribution policy, as set forth above, will otherwise be adversely affected.

FEDERAL INCOME TAX MATTERS

The following discussion of federal income tax matters is based on the advice of Kirkpatrick & Lockhart LLP, counsel to the Fund. The Fund intends to elect to be treated and to qualify each year as a regulated investment company under the Code. Accordingly, the Fund intends to satisfy certain requirements relating to sources of its income and diversification of its assets and to distribute substantially all of its net income and net short-term and long-term capital gains (after reduction by any available capital loss carryforwards) in accordance with the timing requirements imposed by the Code, so as to maintain its regulated investment company status and to avoid paying any federal income or excise tax. To the extent it qualifies for treatment as a regulated investment company and satisfies the above-mentioned distribution requirements, the Fund will not be subject to federal income tax on income paid to its shareholders in the form of dividends or capital gains distributions.

The Fund intends to make regular monthly distributions to Common Shareholders based upon its projected annual cash available from option premiums and dividends. Over time all of the Fund's investment company taxable income will be distributed. The Fund intends to distribute annually any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss). Distributions of the Fund's net capital gain ("capital gain distributions"), if any, are taxable to Common Shareholders as long-term capital gain, regardless of the length of time Common Shares have been held by Common Shareholders. If, for any calendar year, the total distributions exceed the Fund's net investment taxable income and net capital gain, the excess will be treated as a tax-free return of capital to each Common Shareholder (up to the amount of the Common Shareholder's basis in his or her Common Shares) and thereafter as gain from the sale of Shares (assuming the Common Shares are held as a capital asset). The amount treated as a tax-free return of capital will reduce the Common Shareholder's adjusted basis in his or her Shares, thereby increasing his or her potential gain or reducing his or her potential loss on the subsequent sale or other disposition of his or her Common Shares. See below for a summary of the maximum tax rates applicable to capital gain (including capital gain distributions). A corporation that owns Fund shares generally will not be entitled to the dividends received deduction with respect to all (or any prescribed percentage) of the distributions it receives from the Fund. Fund distributions that are attributable to qualified dividend income received by the Fund from certain domestic corporations may be designated by the Fund as being eligible for the dividends received deduction.

The Fund's transactions in options are subject to special and complex federal income tax provisions that may, among other things, (i) convert dividends that would otherwise constitute qualified dividend income into higher taxed short-term capital gain or ordinary income, (ii) treat dividends that would otherwise be eligible for the corporate dividends received deduction as ineligible for such treatment, (iii) disallow, suspend or otherwise limit the allowance of certain losses or deductions, (iv) convert long-term capital gain into short-term capital gain or ordinary income, (v) convert an ordinary loss or deduction into a capital loss (the deductibility of which is more limited) and
(vi) cause the Fund to recognize income or gain without a corresponding receipt of cash.

The taxation of equity options such as the Fund expects to write and purchase is governed by Code Section 1234. Pursuant to Code Section 1234, the premium received by the Fund for selling a call option is not included in income at the time of receipt. If the option expires, the premium is short-term capital gain to the Fund. If the Fund enters into a closing transaction, the difference between the amount paid to close out its position and the premium received is short-term capital gain or loss. If a call option written by the Fund is exercised, thereby requiring the Fund to sell the underlying security, the premium will increase the amount realized upon the sale of the security and any resulting gain or


32

DISTRIBUTIONS

loss will be long-term or short-term, depending upon the holding period of the security. With respect to a put on a stock that is purchased by the Fund, if the option is sold, any resulting gain or loss will be a capital gain or loss, and will be short-term or long-term, depending upon the holding period for the option. If the option expires, the resulting loss is a capital loss and is short-term or long-term, depending upon the holding period for the option. If the option is exercised, the amount paid to acquire the position reduces the amount realized on the underlying security in determining gain or loss. Because the Fund does not have control over the exercise of the call options it writes, such exercise or other required sales of the underlying securities may cause the Fund to realize capital gains or losses at inopportune times.

In the case of Fund transactions involving many listed index options and any listed non-equity options, Code Section 1256 generally will require any gain or loss arising from the lapse, closing out or exercise of such positions to be treated as 60% long-term and 40% short-term capital gain or loss, although foreign currency gains or losses arising from certain of these positions may be treated as ordinary income or loss. In addition, the Fund generally will be required to "mark to market" (i.e., treat as sold for fair market value) each such position which it holds at the close of each taxable year. If a Section 1256 Contract held by the Fund at the end of a taxable year is sold in the following year, the amount of any gain or loss realized on such sale will be adjusted to reflect the gain or loss previously taken into account under the "mark to market" rules. Section 1256 Contracts include certain options contracts, certain regulated futures contracts, and certain other financial contracts.

Notwithstanding any of the foregoing, the Fund may recognize gain (but not loss) from a constructive sale of certain "appreciated financial positions" if the Fund enters into a short sale, offsetting notional principal contract, or forward contract transaction with respect to the appreciated position or substantially identical property. Appreciated financial positions subject to this constructive sale treatment are interests (including options and forward contracts and short sales) in stock and certain other instruments. Constructive sale treatment does not apply to certain transactions closed in the 90-day period ending with the 30th day after the close of the taxable year, if certain conditions are met.

The Code contains special rules that apply to "straddles," defined generally as the holding of "offsetting positions with respect to personal property." For example, the straddle rules normally apply when a taxpayer holds stock and an offsetting option with respect to such stock or substantially identical stock or securities. In general, investment positions will be offsetting if there is a substantial diminution in the risk of loss from holding one position by reason of holding one or more other positions. The Fund expects that the call options it writes on portfolio securities will generally be "qualified covered calls" that are exempt from the straddle rules. To meet the qualified covered call option exemption, a stock-plus-covered-call position cannot be part of a larger straddle and must meet a number of other conditions, including that the option is written more than 30 days prior to expiration and is not "deep-in-the-money" as defined in the Code. The Fund may enter into certain investments that may constitute positions in a straddle. If two or more positions constitute a straddle, recognition of a realized loss from one position must be deferred to the extent of unrecognized gain in an offsetting position. In addition, long-term capital gain may be recharacterized as short-term capital gain, or short-term capital loss as long-term capital loss. Interest and other carrying charges allocable to personal property that is part of a straddle are not currently deductible but must instead be capitalized. Similarly, "wash sale" rules apply to prevent the recognition of loss by the Fund from the disposition of stock or securities at a loss in a case in which identical or substantially identical stock or securities (or an option to acquire such property) is or has been acquired within a prescribed period.

The Code allows a taxpayer to elect to offset gains and losses from positions that are part of a "mixed straddle." A "mixed straddle" is any straddle in which one or more but not all positions are Section 1256 Contracts. The Fund may be eligible to elect to establish one or more mixed straddle

DISTRIBUTIONS

accounts for certain of its mixed straddle trading positions. The mixed straddle account rules require a daily "marking to market" of all open positions in the account and a daily netting of gains and losses from positions in the account. At the end of a taxable year, the annual net gains or losses from the mixed straddle account are recognized for tax purposes. The application of the mixed straddle account rules is not entirely clear. Therefore, there is no assurance that a mixed straddle account election by the Fund will be accepted by the IRS.

Gain or loss from a short sale of property is generally considered as capital gain or loss to the extent the property used to close the short sale constitutes a capital asset in the Fund's hands. Except with respect to certain situations where the property used to close a short sale has a long-term holding period on the date the short sale is entered into, gains on short sales generally are short-term capital gains. A loss on a short sale will be treated as a long-term capital loss if, on the date of the short sale, "substantially identical property" has been held by the Fund for more than one year. In addition, these rules may also terminate the running of the holding period of "substantially identical property" held by the Fund.

Gain or loss on a short sale will generally not be realized until such time as the short sale is closed. However, as described above in the discussion of constructive sales, if the Fund holds a short sale position with respect to securities that have appreciated in value, and it then acquires property that is the same as or substantially identical to the property sold short, the Fund generally will recognize gain on the date it acquires such property as if the short sale were closed on such date with such property. Similarly, if the Fund holds an appreciated financial position with respect to securities and then enters into a short sale with respect to the same or substantially identical property, the Fund generally will recognize gain as if the appreciated financial position were sold at its fair market value on the date it enters into the short sale. The subsequent holding period for any appreciated financial position that is subject to these constructive sale rules will be determined as if such position were acquired on the date of the constructive sale.

Under the "Jobs and Growth Tax Relief Reconciliation Act of 2003" (the "Tax Act"), certain dividend distributions paid by the Fund (whether paid in cash or reinvested in additional Fund shares) to individual taxpayers are taxed at rates applicable to net long-term capital gains (15%, or 5% for individuals in the 10% or 15% tax brackets). This tax treatment applies only if certain holding period and other requirements are satisfied by the Common Shareholder and the dividends are attributable to qualified dividend income received by the Fund itself. For this purpose, "qualified dividend income" means dividends received by the Fund from U.S. corporations and "qualified foreign corporations," provided that the Fund satisfies certain holding period and other requirements in respect of the stock of such corporations. Dividends received on shares of stock that are subject to a covered call option that is "in-the-money" when written, will not constitute qualified dividend income. Gains on option positions and other short-term gains, interest income and non-qualified dividends are not eligible for the lower tax rate. The special rules relating to the taxation of ordinary income dividends paid by the Fund generally apply to taxable years beginning after December 31, 2002 and beginning before January 1, 2009. Thereafter, the Fund's distributions that are characterized as dividends, other than capital gain distributions, will be fully taxable at ordinary income tax rates unless further Congressional action is taken. There can be no assurance as to what portion of the Fund's dividend distributions will qualify for favorable treatment under the Tax Act.

The Fund will inform Common Shareholders of the source and tax status of all distributions promptly after the close of each calendar year.

Selling Common Shareholders will generally recognize gain or loss in an amount equal to the difference between the Common Shareholder's adjusted tax basis in the Common Shares sold and the


34

DISTRIBUTIONS

amount received. If the Common Shares are held as a capital asset, the gain or loss will be a capital gain or loss. The maximum tax rate applicable to net capital gains recognized by individuals and other non-corporate taxpayers is (i) the same as the maximum ordinary income tax rate for gains recognized on the sale of capital assets held for one year or less, or (ii) 15% for gains recognized on the sale of capital assets held for more than one year (as well as certain capital gain distributions) (5% for individuals in the 10% or 15% tax brackets). Any loss on a disposition of Common Shares held for six months or less will be treated as a long-term capital loss to the extent of any capital gain distributions received with respect to those Common Shares. For purposes of determining whether Common Shares have been held for six months or less, the holding period is suspended for any periods during which the Common Shareholder's risk of loss is diminished as a result of holding one or more other positions in substantially similar or related property, or through certain options or short sales. Any loss realized on a sale or exchange of Common Shares will be disallowed to the extent those Common Shares are replaced by other Common Shares within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the Common Shares (whether through the reinvestment of distributions, which could occur, for example, if the Common Shareholder is a participant in the Plan (as defined below) or otherwise). In that event, the basis of the replacement Common Shares will be adjusted to reflect the disallowed loss.

An investor should be aware that, if Common Shares are purchased shortly before the record date for any taxable distribution (including a capital gain distribution), the purchase price likely will reflect the value of the distribution and the investor then would receive a taxable distribution likely to reduce the trading value of such Common Shares, in effect resulting in a taxable return of some of the purchase price. Taxable distributions to individuals and certain other non-corporate Common Shareholders, including those who have not provided their correct taxpayer identification number and other required certifications, may be subject to "backup" federal income tax withholding at the fourth lowest rate of tax applicable to a single individual (in 2004, 28%).

An investor should also be aware that the benefits of the reduced tax rate applicable to long-term capital gains and qualified dividend income may be impacted by the application of the alternative minimum tax to individual shareholders.

Finally, the Tax Act was only recently enacted, and its application is subject to interpretation by and guidance from the Treasury Department and the IRS and subject to change with retroactive effect.

The foregoing briefly summarizes some of the important federal income tax consequences to Common Shareholders of investing in Common Shares, reflects the federal tax law as of the date of this Prospectus, and does not address special tax rules applicable to certain types of investors, such as corporate and foreign investors. Unless otherwise noted, this discussion assumes that an investor is a U.S. person and holds Common Shares as a capital asset. This discussion is based upon present provisions of the Code, the regulations promulgated thereunder, and judicial and administrative ruling authorities, all of which are subject to change or differing interpretations by the courts or the IRS retroactively or prospectively. Investors should consult their tax advisors regarding other federal, state or local tax considerations that may be applicable in their particular circumstances, as well as any proposed tax law changes.

Dividend reinvestment plan

Pursuant to the Fund's dividend reinvestment plan (the "Plan"), a Common Shareholder may elect to have all distributions (including all capital gain dividends) automatically reinvested in Common Shares. Common Shareholders may elect to participate in the Plan by completing the dividend reinvestment


35

DIVIDEND REINVESTMENT PLAN

plan application form. Common Shareholders electing not to participate in the Plan will receive all distributions in cash paid by check mailed directly to them by PFPC Inc., as dividend paying agent.

PFPC Inc. (the "Plan Agent") serves as agent for the Common Shareholders in administering the Plan. Common Shareholders who elect not to participate in the Plan will receive all Fund distributions in cash paid by check mailed directly to the Common Shareholder of record (or if the Common Shares are held in street or other nominee name, then to the nominee) by PFPC Inc., as disbursing agent. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by written notice if received by the Plan Agent prior to any distribution record date.

Common Shares will be acquired by the Plan Agent or an independent broker-dealer for the participants' accounts, depending upon the circumstances described below, either (i) through receipt of additional previously authorized but unissued Common Shares from the Fund ("newly issued Common Shares") or (ii) by purchase of outstanding Common Shares on the open market ("open-market purchases") on the New York Stock Exchange or elsewhere. If, on the payment date for the distribution, the net asset value per Common Share is equal to or less than the market price per Common Share plus estimated brokerage commissions (such condition being referred to herein as "market premium"), the Plan Agent will invest the distribution amount in newly issued Common Shares on behalf of the participants. The number of newly issued Common Shares to be credited to each participant's account will be determined by dividing the dollar amount of the distribution by the net asset value per Common Share on the date the Common Shares are issued, provided that the maximum discount from the then current market price per Common Share on the date of issuance may not exceed 5%. If on the distribution payment date the net asset value per Common Share is greater than the market value plus estimated brokerage commissions (such condition being referred to herein as "market discount"), the Plan Agent will invest the distribution amount in Common Shares acquired on behalf of the participants in open-market purchases.

In the event of a market discount on the distribution payment date, the Plan Agent will have up to 30 days after the distribution payment date to invest the distribution amount in Common Shares acquired in open-market purchases. If, before the Plan Agent has completed its open-market purchases, the market price of a Common Share exceeds the net asset value per Common Share, the average per Common Share purchase price paid by the Plan Agent may exceed the net asset value of the Fund's Common Shares, resulting in the acquisition of fewer Common Shares than if the distribution had been paid in newly issued Common Shares on the distribution payment date. Therefore, the Plan provides that if the Plan Agent is unable to invest the full distribution amount in open-market purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Agent will cease making open-market purchases and will invest the uninvested portion of the distribution amount in newly issued Common Shares.

The Plan Agent maintains all Common Shareholders' accounts in the Plan and furnishes written confirmation of all transactions in the accounts, including information needed by Common Shareholders for tax records. Common Shares in the account of each Plan participant will be held by the Plan Agent on behalf of the Plan participant, and each Common Shareholder proxy will include those Common Shares purchased or received pursuant to the Plan. The Plan Agent will forward all proxy solicitation materials to participants and vote proxies for Common Shares held pursuant to the Plan in accordance with the instructions of the participants. In the case of Common Shareholders such as banks, brokers or nominees that hold Common Shares for others who are the beneficial owners, the Plan Agent will administer the Plan on the basis of the number of Common Shares certified from time to time by the record Common Shareholder's name and held for the account of beneficial owners who participate in the Plan.


36

DIVIDEND REINVESTMENT PLAN

There will be no brokerage charges with respect to Common Shares issued directly by the Fund as a result of distributions payable either in Common Shares or in cash. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent's open-market purchases in connection with the reinvestment of distributions.

Common Shareholders participating in the Plan may receive benefits not available to Common Shareholders not participating in the Plan. If the market price (plus commissions) of the Fund's Common Shares is above their net asset value, participants in the Plan will receive Common Shares of the Fund at less than they could otherwise purchase them and will have Common Shares with a cash value greater than the value of any cash distribution they would have received on their Common Shares. If the market price plus commissions is below the net asset value, participants will receive distributions in Common Shares with a net asset value greater than the per Common Share value of any cash distribution they would have received on their Common Shares. However, there may be insufficient Common Shares available in the market to make distributions in Common Shares at prices below the net asset value. Also, since the Fund does not redeem its Common Shares, the price on resale may be more or less than the net asset value.

Experience under the Plan may indicate that changes are desirable. Accordingly, upon 30 days' notice to Plan participants, the Fund reserves the right to amend or terminate the Plan. A Plan participant will be charged a $5.00 service charge and pay brokerage charges whenever he or she directs the Plan Agent to sell Common Shares held in a distribution reinvestment account.

All correspondence concerning the Plan should be directed to the Plan Agent at PFPC Inc., P.O. Box 43027, Providence, Rhode Island 02940-3027. Please call 1-800-331-1710 between the hours of 9:00 a.m. and 5:00 p.m. Eastern Standard Time if you have questions regarding the Plan.

Description of capital structure

The Fund is an unincorporated business trust established under the laws of The Commonwealth of Massachusetts by an Agreement and Declaration of Trust dated and filed with the Secretary of The Commonwealth on August 11, 2004 (the "Declaration of Trust"). The Declaration of Trust provides that the Board may authorize separate classes of shares of beneficial interest. The Board has authorized an unlimited number of Common Shares. The Fund intends to hold annual meetings of Common Shareholders in compliance with the requirements of the New York Stock Exchange.

COMMON SHARES

The Declaration of Trust permits the Fund to issue an unlimited number of full and fractional common shares of beneficial interest, $0.01 par value per share. Each Common Share represents an equal proportionate interest in the assets of the Fund with each other Common Share in the Fund. Holders of Common Shares will be entitled to the payment of distributions when, as and if declared by the Board. The 1940 Act or the terms of any future borrowings or issuance of preferred shares may limit the payment of distributions to the holders of Common Shares. Each whole Common Share shall be entitled to one vote as to matters on which it is entitled to vote pursuant to the terms of the Declaration of Trust on file with the SEC. Upon liquidation of the Fund, after paying or adequately providing for the payment of all liabilities of the Fund and the liquidation preference with respect to any outstanding preferred shares, and upon receipt of such releases, indemnities and refunding agreements as they deem necessary for their protection, the Board may distribute the remaining assets of the Fund among the holders of the Common Shares. The Declaration of Trust provides that Common Shareholders are not liable for any liabilities of the Fund, and permits inclusion of a clause to that effect in agreements entered into by the Fund and in coordination with the Fund's By-laws indemnifies shareholders against any such liability. Although shareholders of an unincorporated


37

DESCRIPTION OF CAPITAL STRUCTURE

business trust established under Massachusetts law, in certain limited circumstances, may be held personally liable for the obligations of the business trust as though they were general partners, the provisions of the Fund's Declaration of Trust and By-laws described in the foregoing sentence make the likelihood of such personal liability remote.

The Fund has no current intention to issue preferred shares or to borrow money. However, if at some future time, there are any borrowings or preferred shares outstanding, the Fund may not be permitted to declare any cash distribution on its Common Shares, unless at the time of such declaration, (i) all accrued distributions on preferred shares or accrued interest on borrowings have been paid and (ii) the value of the Fund's total assets (determined after deducting the amount of such distribution), less all liabilities and indebtedness of the Fund not represented by senior securities, is at least 300% of the aggregate amount of such securities representing indebtedness and at least 200% of the aggregate amount of securities representing indebtedness plus the aggregate liquidation value of the outstanding preferred shares (expected to equal the aggregate original purchase price of the outstanding preferred shares plus redemption premium, if any, together with any accrued and unpaid distributions thereon, whether or not earned or declared and on a cumulative basis). In addition to the requirements of the 1940 Act, the Fund may be required to comply with other asset coverage requirements as a condition of the Fund obtaining a rating of preferred shares from a nationally recognized statistical rating agency (a "Rating Agency"). These requirements may include an asset coverage test more stringent than under the 1940 Act. This limitation on the Fund's ability to make distributions on its Common Shares could in certain circumstances impair the ability of the Fund to maintain its qualification for taxation as a regulated investment company for federal income tax purposes. If the Fund were in the future to issue preferred shares or borrow money, it would intend, however, to the extent possible to purchase or redeem preferred shares or reduce borrowings from time to time to maintain compliance with such asset coverage requirements and may pay special distributions to the holders of the preferred shares in certain circumstances in connection with any potential impairment of the Fund's status as a regulated investment company. See "Distributions-Federal income tax matters." Depending on the timing of any such redemption or repayment, the Fund may be required to pay a premium in addition to the liquidation preference of the preferred shares to the holders thereof.

The Fund has no present intention of offering additional Common Shares, except as described herein. Other offerings of its Common Shares, if made, will require approval of the Board. Any additional offering will not be sold at a price per Common Share below the then current net asset value (exclusive of underwriting discounts and commissions) except in connection with an offering to existing Common Shareholders or with the consent of a majority of the Fund's outstanding Common Shares. The Common Shares have no preemptive rights.

The Fund generally will not issue Common Share certificates. However, upon written request to the Fund's transfer agent, a share certificate will be issued for any or all of the full Common Shares credited to an investor's account. Common Share certificates that have been issued to an investor may be returned at any time.

REPURCHASE OF COMMON SHARES AND OTHER DISCOUNT MEASURES

Because shares of closed-end management investment companies frequently trade at a discount to their net asset values, the Board has determined that from time to time it may be in the interest of Common Shareholders for the Fund to take corrective actions. The Board, in consultation with Eaton Vance, will review at least annually the possibility of open market repurchases and/or tender offers for the Common Shares and will consider such factors as the market price of the Common Shares, the net asset value of the Common Shares, the liquidity of the assets of the Fund, the effect on the Fund's expenses, whether such transactions would impair the Fund's status as a regulated investment company or result in a failure to comply with applicable asset coverage requirements, general economic


38

DESCRIPTION OF CAPITAL STRUCTURE

conditions and such other events or conditions, which may have a material effect on the Fund's ability to consummate such transactions. There are no assurances that the Board will, in fact, decide to undertake either of these actions or, if undertaken, that such actions will result in the Common Shares trading at a price equal to or approximates their net asset value. In recognition of the possibility that the Common Shares might trade at a discount to net asset value and that any such discount may not be in the interest of Common Shareholders, the Board, in consultation with Eaton Vance, from time to time may review possible actions to reduce any such discount.

PREFERRED SHARES

The Fund has no current intention of issuing any shares other than the Common Shares. However, the Declaration of Trust authorizes the issuance of an unlimited number of shares of beneficial interest with preference rights (the "preferred shares") in one or more series, with rights as determined by the Board, by action of the Board without the approval of the Common Shareholders.

Under the requirements of the 1940 Act, the Fund must, immediately after the issuance of any preferred shares, have an "asset coverage" of at least 200%. Asset coverage means the ratio which the value of the total assets of the Fund, less all liability and indebtedness not represented by senior securities (as defined in the 1940 Act), bears to the aggregate amount of senior securities representing indebtedness of the Fund, if any, plus the aggregate liquidation preference of the preferred shares. If the Fund seeks a rating of preferred shares, asset coverage requirements, in addition to those set forth in the 1940 Act, may be imposed. The liquidation value of any preferred shares would be expected to equal their aggregate original purchase price plus redemption premium, if any, together with any accrued and unpaid distributions thereon (on a cumulative basis), whether or not earned or declared. The terms of any preferred shares, including their distribution rate, voting rights, liquidation preference and redemption provisions, will be determined by the Board (subject to applicable law and the Fund's Declaration of Trust) if and when it authorizes preferred shares. The Fund may issue preferred shares that provide for the periodic redetermination of the dividend rate at relatively short intervals through an auction or remarketing procedure, although the terms of such preferred shares may also enable the Fund to lengthen such intervals. At times, the distribution rate as redetermined on any preferred shares could approach or exceed the Fund's return after expenses on the investment of proceeds from the preferred shares and the Fund's leveraged capital structure would result in a lower rate of return to Common Shareholders than if the Fund were not so structured.

In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Fund, the terms of any preferred shares may entitle the holders of preferred shares to receive a preferential liquidating distribution (expected to equal the original purchase price per share plus redemption premium, if any, together with accrued and unpaid dividends, whether or not earned or declared and on a cumulative basis) before any distribution of assets is made to holders of Common Shares. After payment of the full amount of the liquidating distribution to which they are entitled, the preferred shareholders would not be entitled to any further participation in any distribution of assets by the Fund. Holders of preferred shares, voting as a class, shall be entitled to elect two of the Fund's Trustees, if any preferred shares are issued. Under the 1940 Act, if at any time dividends on the preferred shares are unpaid in an amount equal to two full years' dividends thereon, the holders of all outstanding preferred shares, voting as a class, will be allowed to elect a majority of the Board until all dividends in default have been paid or declared and set apart for payment. In addition, if required by a Rating Agency rating the preferred shares or if the Board determines it to be in the best interests of the Common Shareholders, issuance of the preferred shares may result in more restrictive provisions than required by the 1940 Act being imposed. In this regard, holders of the preferred shares may be entitled to elect a majority of the Fund's Board in other circumstances, for example, if one payment on the preferred shares is in arrears.


39

DESCRIPTION OF CAPITAL STRUCTURE

In the event of any future issuance of preferred shares, the Fund likely would seek a credit rating for such preferred shares from a Rating Agency. In such event, as long as preferred shares are outstanding, the composition of its portfolio will reflect guidelines established by such Rating Agency. Based on previous guidelines established by such Rating Agencies for the securities of other issuers, the Fund anticipates that the guidelines with respect to any preferred shares would establish a set of tests for portfolio composition and asset coverage that supplement (and in some cases are more restrictive than) the applicable requirements under the 1940 Act. Although, at this time, no assurance can be given as to the nature or extent of the guidelines, which may be imposed in connection with obtaining a rating of any preferred shares, the Fund anticipates that such guidelines would include asset coverage requirements that are more restrictive than those under the 1940 Act, restrictions on certain portfolio investments and investment practices, requirements that the Fund maintain a portion of its assets in short-term, high-quality, fixed-income securities and certain mandatory redemption requirements relating to any preferred shares. No assurance can be given that the guidelines actually imposed with respect to any preferred shares by such Rating Agency would be more or less restrictive than as described in this Prospectus.

CREDIT FACILITY/COMMERCIAL PAPER PROGRAM

The Fund has no current intention to borrow money for the purpose of obtaining investment leverage. In the event the Fund in the future determines to engage in investment leverage, in whole or in part, through borrowings, the Fund may enter into definitive agreements with respect to a credit facility/commercial paper program or other borrowing program. The Fund may negotiate with commercial banks to arrange a credit facility/commercial paper program pursuant to which the Fund would expect to be entitled to borrow up to a specified amount. Any such borrowings would constitute financial leverage. Such a facility/commercial paper program would not be expected to be convertible into any other securities of the Fund, outstanding amounts would be expected to be prepayable by the Fund prior to final maturity without significant penalty and there are not expected to be any sinking fund or mandatory retirement provisions. Outstanding amounts would be payable at maturity or such earlier times as required by the agreement. The Fund may be required to prepay outstanding amounts under the facility/program or incur a penalty rate of interest in the event of the occurrence of certain events of default. The Fund would be expected to indemnify the lenders under the facility/program against liabilities they may incur in connection with the facility/program.

In addition, the Fund expects that any such credit facility/program would contain covenants that, among other things, likely would limit the Fund's ability to pay distributions in certain circumstances, incur additional debt, change its fundamental investment policies and engage in certain transactions, including mergers and consolidations, and may require asset coverage ratios in addition to those required by the 1940 Act. The Fund may be required to pledge its assets and to maintain a portion of its assets in cash or high-grade securities as a reserve against interest or principal payments and expenses. The Fund expects that any credit facility/program would have customary covenant, negative covenant and default provisions. There can be no assurance that the Fund will enter into an agreement for a credit facility/program on terms and conditions representative of the foregoing, or that additional material terms will not apply. In addition, if entered into, any such credit facility/program may in the future be replaced or refinanced by one or more credit facilities having substantially different terms or by the issuance of preferred shares or debt securities.

EFFECTS OF POSSIBLE FUTURE LEVERAGE

As discussed above, the Fund has no current intention to issue preferred shares or to borrow money for the purpose of obtaining investment leverage. In the event that the Fund determines in the future to utilize investment leverage, there can be no assurance that such a leveraging strategy would be


40

DESCRIPTION OF CAPITAL STRUCTURE

successful during any period in which it is employed. Leverage creates risks for Common Shareholders, including the likelihood of greater volatility of net asset value and market price of the Common Shares and the risk that fluctuations in distribution rates on any preferred shares or fluctuations in borrowing costs may affect the return to Common Shareholders. To the extent the amounts available for distribution derived from securities purchased with proceeds received from leverage exceed the cost of leverage, the Fund's distributions would be greater than if leverage had not been used. Conversely, if the amounts available for distribution derived from securities purchased with such proceeds are not sufficient to cover the cost of leverage, distributions to Common Shareholders would be less than if leverage had not been used. In the latter case, Eaton Vance, in its best judgment, may nevertheless determine to maintain the Fund's leveraged position if it deems such action to be appropriate. The costs of an offering of preferred shares and/or a borrowing program would be borne by Common Shareholders and consequently would result in a reduction of the net asset value of Common Shares.

In addition, the fee paid to Eaton Vance will be calculated on the basis of the Fund's average daily gross assets, including proceeds from the issuance of preferred shares and/or borrowings, so the fees would be higher if leverage is utilized. In this regard, holders of preferred shares would not bear the investment advisory fee. Rather, Common Shareholders would bear the portion of the investment advisory fee attributable to the assets purchased with the proceeds of the preferred shares offering.

ANTI-TAKEOVER PROVISIONS IN THE DECLARATION OF TRUST

The Declaration of Trust includes provisions that could have the effect of limiting the ability of other entities or persons to acquire control of the Fund or to change the composition of its Board and could have the effect of depriving Common Shareholders of an opportunity to sell their Common Shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund. These provisions may have the effect of discouraging attempts to acquire control of the Fund, which attempts could have the effect of increasing the expenses of the Fund and interfering with the normal operation of the Fund. The Board is divided into three classes, with the term of one class expiring at each annual meeting of Common Shareholders. At each annual meeting, one class of Trustees is elected to a three-year term. This provision could delay for up to two years the replacement of a majority of the Board. A Trustee may be removed from office only for cause by a written instrument signed by the remaining Trustees or by a vote of the holders of at least two-thirds of the class of shares of the Fund that elected such Trustee and are entitled to vote on the matter.

In addition, the Declaration of Trust requires the favorable vote of the holders of at least 75% of the outstanding shares of each class of the Fund, voting as a class, then entitled to vote to approve, adopt or authorize certain transactions with 5%-or-greater holders of a class of shares and their associates, unless the Board shall by resolution have approved a memorandum of understanding with such holders, in which case normal voting requirements would be in effect. For purposes of these provisions, a 5%-or-greater holder of a class of shares (a "Principal Shareholder") refers to any person who, whether directly or indirectly and whether alone or together with its affiliates and associates, beneficially owns 5% or more of the outstanding shares of any class of beneficial interest of the Fund. The transactions subject to these special approval requirements are: (i) the merger or consolidation of the Fund or any subsidiary of the Fund with or into any Principal Shareholder; (ii) the issuance of any securities of the Fund to any Principal Shareholder for cash; (iii) the sale, lease or exchange of all or any substantial part of the assets of the Fund to any Principal Shareholder (except assets having an aggregate fair market value of less than $1,000,000, aggregating for the purpose of such computation all assets sold, leased or exchanged in any series of similar transactions within a twelve-month period); or (iv) the sale, lease or exchange to the Fund or any subsidiary thereof, in exchange for securities of the Fund, of any assets of any Principal Shareholder (except assets having an aggregate fair market


41

DESCRIPTION OF CAPITAL STRUCTURE

value of less than $1,000,000, aggregating for the purposes of such computation all assets sold, leased or exchanged in any series of similar transactions within a twelve-month period).

The Board has determined that provisions with respect to the Board and the 75% voting requirements described above, which voting requirements are greater than the minimum requirements under Massachusetts law or the 1940 Act, are in the best interest of Common Shareholders generally. Reference should be made to the Declaration of Trust on file with the SEC for the full text of these provisions.

CONVERSION TO OPEN-END FUND

The Fund may be converted to an open-end management investment company at any time if approved by the lesser of (i) two-thirds or more of the Fund's then outstanding Common Shares and preferred shares (if any), each voting separately as a class, or (ii) more than 50% of the then outstanding Common Shares and preferred shares (if any), voting separately as a class if such conversion is recommended by at least 75% of the Trustees then in office. If approved in the foregoing manner, conversion of the Fund could not occur until 90 days after the shareholders' meeting at which such conversion was approved and would also require at least 30 days' prior notice to all shareholders. Conversion of the Fund to an open-end management investment company also would require the redemption of any outstanding preferred shares and could require the repayment of borrowings, which would eliminate any future leveraged capital structure of the Fund with respect to the Common Shares. In the event of conversion, the Common Shares would cease to be listed on the New York Stock Exchange or other national securities exchange or market system. The Board believes that the closed-end structure is desirable, given the Fund's investment objectives and policies. Investors should assume, therefore, that it is unlikely that the Board would vote to convert the Fund to an open-end management investment company. Shareholders of an open-end management investment company may require the company to redeem their shares at any time (except in certain circumstances as authorized by or under the 1940 Act) at their net asset value, less such redemption charge, if any, as might be in effect at the time of a redemption. If the Fund were to convert to an open-end investment company, the Fund expects it would pay all such redemption requests in cash, but would likely reserve the right to pay redemption requests in a combination of cash or securities. If such partial payment in securities were made, investors may incur brokerage costs in converting such securities to cash. If the Fund were converted to an open-end fund, it is likely that new Common Shares would be sold at net asset value plus a sales load.

The Fund has granted to the Underwriters an option, exercisable for 45 days from the date of this Prospectus, to purchase up to an additional Common Shares to cover over-allotments, if any, at the initial offering price. The Underwriters may exercise such option solely for the purpose of covering underwriting over-allotments incurred in the sale of the Common Shares offered hereby. To the extent that the Underwriters exercise this option, each of the Underwriters will have a firm commitment, subject to certain conditions, to purchase an additional number of Common Shares proportionate to such Underwriter's initial commitment.

The Fund has agreed to pay a commission to the Underwriters in the amount of $0.90 per Common Share (4.50% of the public offering price per Common Share). The Representatives have advised the Fund that the Underwriters may pay up to $ per Common Share from such commission to selected dealers who sell the Common Shares and that such dealers may reallow a concession of up to $ per Common Share to certain other dealers who sell Common Shares. Eaton Vance or an affiliate has agreed to (i) reimburse all organizational costs and (ii) pay all offering costs of the Fund (other than sales loads) that exceed $0.04 per Common Share. Investors must pay for any Common Shares purchased on or before , 2004.

Prior to this offering, there has been no public market for the Common Shares or any other securities of the Fund. Consequently, the offering price for the Common Shares was determined by negotiation among the Fund and the Representatives. There can be no assurance, however, that the price at which Common Shares sell after this offering will not be lower than the price at which they are sold by the


43

UNDERWRITING

Underwriters or that an active trading market in the Common Shares will develop and continue after this offering. The minimum investment requirement is 100 Common Shares ($2,000).

The Fund, Eaton Vance and Rampart have each agreed to indemnify the several Underwriters for or to contribute to the losses arising out of certain liabilities, including liabilities under the Securities Act of 1933, as amended.

The Fund has agreed not to offer, sell or register with the Securities and Exchange Commission any additional equity securities of the Fund, other than issuances of Common Shares, including pursuant to the Fund's Plan, and issuances in connection with any preferred shares, each as contemplated in this Prospectus, for a period of 180 days after the date of the Underwriting Agreement without the prior written consent of the Representatives.

The Representatives have informed the Fund that the Underwriters do not intend to confirm sales to any accounts over which they exercise discretionary authority.

In connection with this offering, the Underwriters may purchase and sell Common Shares in the open market. These transactions may include over-allotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with this offering. Stabilizing transactions consist of certain bids or purchases for the purpose of preventing or retarding a decline in the market price of the Common Shares and syndicate short positions involve the sale by the Underwriters of a greater number of Common Shares than they are required to purchase from the Fund in this offering. The Underwriters also may impose a penalty bid, whereby selling concessions allowed to syndicate members or other broker-dealers in respect of the Common Shares sold in this offering for their account may be reclaimed by the syndicate if such Common Shares are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the Common Shares, which may be higher than the price that might otherwise prevail in the open market; and these activities, if commenced, may be discontinued at any time without notice. These transactions may be effected on the New York Stock Exchange or otherwise.

The Fund anticipates that the Representatives and certain other Underwriters may from time to time act as brokers or dealers in connection with the execution of its portfolio transactions after they have ceased to be Underwriters and, subject to certain restrictions, may act as such brokers while they are Underwriters.

In connection with the offering, certain of the Underwriters or selected dealers may distribute prospectuses electronically.

Eaton Vance (and not the Fund) has agreed pursuant to an additional compensation agreement (the "Additional Compensation Agreement") to pay to certain qualifying Underwriters who meet specified sales targets ("Qualifying Underwriters"), quarterly in arrears, an annual fee of up to 0.15% of the Fund's average daily gross assets attributable to Common Shares sold by such Qualifying Underwriters (including a proportionate share of assets that may in the future be acquired using leverage). Such sales targets may be waived or lowered with respect to any Underwriter in the sole discretion of Eaton Vance. These fee payments will remain in effect only so long as the Advisory Agreement remains in effect between the Fund and Eaton Vance or any successor in interest or affiliate of Eaton Vance, as and to the extent that such Advisory Agreement is renewed periodically in accordance with the 1940 Act. The sum of the additional compensation payable to the Qualifying Underwriters will not exceed % of the aggregate initial offering price of the Common Shares offered hereby.
will receive additional compensation which will not exceed % of the aggregate initial offering price of the Common Shares offered hereby.

Pursuant to a shareholder servicing agreement (the "Shareholder Servicing Agreement") between UBS Securities LLC (the "Shareholder Servicing Agent") and Eaton Vance, the Shareholder Servicing Agent

For these services, Eaton Vance will pay the Shareholder Servicing Agent a fee computed daily and payable quarterly equal, on an annual basis, to 0.10% of the Fund's average daily gross assets. The total of all of the payments payable to the Shareholder Servicing Agent under the Shareholder Servicing Agreement will not exceed % of the aggregate initial offering price of the Common Shares offered hereby. Under the terms of the Shareholder Servicing Agreement, the Shareholder Servicing Agent is relieved from liability to Eaton Vance or the Fund for any act or omission to act in the course of its performance under the Shareholder Servicing Agreement in the absence of bad faith, gross negligence or willful misconduct on the part of the Shareholder Servicing Agent.

Compensation received by pursuant to the Additional Compensation Agreement and compensation received by UBS Securities LLC pursuant to the Shareholder Servicing Agreement together will not exceed 4.50% of the aggregate initial offering price of the Common Shares offered hereby, and the total compensation received by the Underwriters will not exceed 9.00% of the aggregate initial offering price of the Common Shares offered hereby.

THIS STATEMENT OF ADDITIONAL INFORMATION ("SAI") IS NOT A PROSPECTUS AND IS AUTHORIZED FOR DISTRIBUTION TO PROSPECTIVE INVESTORS ONLY IF PRECEDED OR ACCOMPANIED BY THE PROSPECTUS OF EATON VANCE ENHANCED EQUITY INCOME FUND (THE "FUND") DATED , 2004, AS SUPPLEMENTED FROM TIME TO TIME, WHICH IS INCORPORATED HEREIN BY REFERENCE. THIS SAI SHOULD BE READ IN CONJUNCTION WITH SUCH PROSPECTUS, A COPY OF WHICH MAY BE OBTAINED WITHOUT CHARGE BY CONTACTING YOUR FINANCIAL INTERMEDIARY OR CALLING THE FUND AT 1-800-225-6265.

THESE SECURITIES MAY NOT BE SOLD UNTIL THE REGISTRATION STATEMENT FILED WITH THE SECURITIES AND EXCHANGE COMMISSION IS EFFECTIVE. THIS STATEMENT OF ADDITIONAL INFORMATION, WHICH IS NOT A PROSPECTUS, IS NOT AN OFFER TO SELL THESE SECURITIES AND IS NOT SOLICITING AN OFFER TO BUY THESE SECURITIES IN ANY STATE WHERE THE OFFER OR SALE IS NOT PERMITTED.


Capitalized terms used in this SAI and not otherwise defined have the meanings given them in the Fund's Prospectus.

Additional investment information and restrictions

Primary investment strategies are described in the Prospectus. The following is a description of the various investment policies that may be engaged in, whether as a primary or secondary strategy, and a summary of certain attendant risks. Eaton Vance may not buy any of the following instruments or use any of the following techniques unless it believes that doing so will help to achieve the Fund's investment objectives.

Equity investments. As described in the Prospectus, the Fund invests primarily in common stocks.

Preferred Stocks. The Fund may invest in preferred stocks of both domestic and foreign issuers. Under normal market conditions, the Fund expects, with respect to that portion of its total assets invested in preferred stocks, to invest only in preferred stocks of investment grade quality as determined by S&P, Fitch or Moody's or, if unrated, determined to be of comparable quality by Eaton Vance. The foregoing credit quality policies apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event of a downgrade of an assessment of credit quality or the withdrawal of a rating. Preferred stocks involve credit risk, which is the risk that a preferred stock will decline in price, or fail to pay dividends when expected, because the issuer experiences a decline in its financial status. In addition to credit risk, investment in preferred stocks involves certain other risks as more fully described in the Prospectus.

Derivative instruments. Derivative instruments (which are instruments that derive their value from another instrument, security or index) may be purchased or sold to enhance return (which may be considered speculative), to hedge against fluctuations in securities prices or market conditions, or as a substitute for the purchase or sale of securities or currencies. These strategies may be executed through the use of derivative contracts in the U.S. or abroad. In the course of pursuing these investment strategies, the Fund may purchase and sell exchange-listed and over-the-counter put and call options on securities, equity and fixed-income indices and other instruments, purchase and sell futures contracts and options thereon, and enter into various transactions such as swaps, caps, floors or collars. In addition, derivatives may also include new techniques, instruments or strategies that are permitted as regulatory changes occur. Transactions in derivative instruments involve a risk of loss or depreciation due to: unanticipated adverse changes in securities prices, interest rates, indices, or the other financial instruments' prices; the inability to close out a position; default by the counterparty; imperfect correlation between a position and the desired hedge; tax constraints on closing out positions; and portfolio management constraints on securities subject to such transactions. The loss on derivative instruments (other than purchased options) may substantially exceed an investment in these instruments. In addition, the entire premium paid for purchased options may be lost before they can be profitably exercised. Transaction costs are incurred in opening and closing positions. Derivative instruments may sometimes increase or leverage exposure to a particular market risk, thereby increasing price volatility. Over-the-counter ("OTC") derivative instruments, equity swaps and forward sales of stocks involve an enhanced risk that the issuer or counterparty will fail to perform its contractual obligations. Some derivative instruments are not readily marketable or may become illiquid under adverse market conditions. In addition, during periods of market volatility, a commodity exchange may suspend or limit trading in an exchange-traded derivative instrument, which may make the contract temporarily illiquid and difficult to price. Commodity exchanges may also establish daily limits on the amount that the price of a futures contract or futures option can vary from the previous day's settlement price. Once the daily limit is reached, no trades may be made that day at a price beyond the limit. This may prevent the closing out of positions to limit losses. The staff of the SEC takes the position that certain purchased OTC options, and assets used as cover for written OTC options, are illiquid. The ability to terminate OTC derivative instruments may depend on the cooperation of the counterparties to such contracts. For thinly traded derivative instruments, the only


2

ADDITIONAL INVESTMENT INFORMATION AND RESTRICTIONS

source of price quotations may be the selling dealer or counterparty. In addition, certain provisions of the Code limit the use of derivative instruments. The Fund has claimed an exclusion from the definition of a Commodity Pool Operator ("CPO") under the Commodity Exchange Act and therefor is not subject to registration or regulation as a CPO. There can be no assurance that the use of derivative instruments will be advantageous.

Foreign exchange traded futures contracts and options thereon may be used only if the Adviser determines that trading on such foreign exchange does not entail risks, including credit and liquidity risks, that are materially greater than the risks associated with trading on CFTC-regulated exchanges.

SHORT SALES
The Fund may sell a security short if it owns at least an equal amount of the security sold short or another security convertible or exchangeable for an equal amount of the security sold short without payment of further compensation (a short sale against-the-box).

Purchasing securities to close out the short position can itself cause the price of the securities to rise further, thereby exacerbating the loss. Short-selling exposes the Fund to unlimited risk with respect to that security due to the lack of an upper limit on the price to which an instrument can rise. Although the Fund reserves the right to utilize short sales, the Adviser is under no obligation to utilize short sales at all.

SECURITIES LENDING
As described in the Prospectus, the Fund may lend a portion of its portfolio securities to broker-dealers or other institutional borrowers. Loans will be made only to organizations whose credit quality or claims paying ability is considered by the Adviser to be at least investment grade. All securities loans will be collateralized on a continuous basis by cash or U.S. government securities having a value, marked to market daily, of at least 100% of the market value of the loaned securities. The Fund may receive loan fees in connection with loans that are collateralized by securities or on loans of securities for which there is special demand. The Fund may also seek to earn income on securities loans by reinvesting cash collateral in securities consistent with its investment objectives and policies, seeking to invest at rates that are higher than the "rebate" rate that it normally will pay to the borrower with respect to such cash collateral. Any such reinvestment will be subject to the investment policies, restrictions and risk considerations described in the Prospectus and in this SAI.

Securities loans may result in delays in recovering, or a failure of the borrower to return, the loaned securities. The defaulting borrower ordinarily would be liable to the Fund for any losses resulting from such delays or failures, and the collateral provided in connection with the loan normally would also be available for that purpose. Securities loans normally may be terminated by either the Fund or the borrower at any time. Upon termination and the return of the loaned securities, the Fund would be required to return the related cash or securities collateral to the borrower and it may be required to liquidate longer term portfolio securities in order to do so. To the extent that such securities have decreased in value, this may result in the Fund realizing a loss at a time when it would not otherwise do so. The Fund also may incur losses if it is unable to reinvest cash collateral at rates higher than applicable rebate rates paid to borrowers and related administrative costs. These risks are substantially the same as those incurred through investment leverage, and will be subject to the investment policies, restrictions and risk considerations described in the Prospectus and in this SAI.

The Fund will receive amounts equivalent to any interest or other distributions paid on securities while they are on loan, and the Fund will not be entitled to exercise voting or other beneficial rights on loaned securities. The Fund will exercise its right to terminate loans and thereby regain these rights whenever the Adviser considers it to be in the Fund's interest to do so, taking into account the related loss of reinvestment income and other factors.

ADDITIONAL INVESTMENT INFORMATION AND RESTRICTIONS

TEMPORARY INVESTMENTS
The Fund may invest temporarily in cash or cash equivalents. Cash equivalents are highly liquid, short-term securities such as commercial paper, time deposits, certificates of deposit, short-term notes and short-term U.S. government obligations.

INVESTMENT RESTRICTIONS
The following investment restrictions of the Fund are designated as fundamental policies and as such cannot be changed without the approval of the holders of a majority of the Fund's outstanding voting securities, which as used in this SAI means the lesser of (a) 67% of the shares of the Fund present or represented by proxy at a meeting if the holders of more than 50% of the outstanding shares are present or represented at the meeting or (b) more than 50% of outstanding shares of the Fund. As a matter of fundamental policy the Fund may not:

(1) Borrow money, except as permitted by the Investment Company Act of 1940, as amended (the "1940 Act"). The 1940 Act currently requires that any indebtedness incurred by a closed-end investment company have an asset coverage of at least 300%;

(2) Issue senior securities, as defined in the 1940 Act, other than (a) preferred shares which immediately after issuance will have asset coverage of at least 200%, (b) indebtedness which immediately after issuance will have asset coverage of at least 300%, or (c) the borrowings permitted by investment restriction (1) above. The 1940 Act currently defines "senior security" as any bond, debenture, note or similar obligation or instrument constituting a security and evidencing indebtedness and any stock of a class having priority over any other class as to distribution of assets or payment of dividends. Debt and equity securities issued by a closed-end investment company meeting the foregoing asset coverage provisions are excluded from the general 1940 Act prohibition on the issuance of senior securities;

(3) Purchase securities on margin (but the Fund may obtain such short-term credits as may be necessary for the clearance of purchases and sales of securities). The purchase of investment assets with the proceeds of a permitted borrowing or securities offering will not be deemed to be the purchase of securities on margin;

(4) Underwrite securities issued by other persons, except insofar as it may technically be deemed to be an underwriter under the Securities Act of 1933, as amended, in selling or disposing of a portfolio investment;

(5) Make loans to other persons, except by (a) the acquisition of loan interests, debt securities and other obligations in which the Fund is authorized to invest in accordance with its investment objectives and policies, (b) entering into repurchase agreements, and (c) lending its portfolio securities;

(6) Purchase or sell real estate, although it may purchase and sell securities which are secured by interests in real estate and securities of issuers which invest or deal in real estate. The Fund reserves the freedom of action to hold and to sell real estate acquired as a result of the ownership of securities;

(7) Purchase or sell physical commodities or contracts for the purchase or sale of physical commodities. Physical commodities do not include futures contracts with respect to securities, securities indices, currencies, interest or other financial instruments;

(8) With respect to 75% of its total assets, invest more than 5% of its total assets in the securities of a single issuer or purchase more than 10% of the outstanding voting securities of a single issuer, except obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities and except securities of other investment companies; and


4

ADDITIONAL INVESTMENT INFORMATION AND RESTRICTIONS

(9) Invest 25% or more of its total assets in any single industry or group of industries (other than securities issued or guaranteed by the U.S. government or its agencies or instrumentalities).

The Fund may borrow money as a temporary measure for extraordinary or emergency purposes, including the payment of dividends and the settlement of securities transactions which otherwise might require untimely dispositions of Fund securities. The 1940 Act currently requires that the Fund have 300% asset coverage with respect to all borrowings other than temporary borrowings.

For purposes of construing restriction (9), a large economic or market sector shall not be construed as a group of industries.

The Fund has adopted the following nonfundamental investment policy which may be changed by the Board without approval of the Fund's shareholders. As a matter of nonfundamental policy, the Fund may not make short sales of securities or maintain a short position, unless at all times when a short position is open it either owns an equal amount of such securities or owns securities convertible into or exchangeable, without payment of any further consideration, for securities of the same issue as, and equal in amount to, the securities sold short.

Upon the Board's approval, the Fund may invest more than 10% of its total assets in one or more other management investment companies (or may invest in affiliated investment companies) to the extent permitted by the 1940 Act and rules thereunder.

Whenever an investment policy or investment restriction set forth in the Prospectus or this SAI states a maximum percentage of assets that may be invested in any security or other assets or describes a policy regarding quality standards, such percentage limitation or standard shall be determined immediately after and as a result of the Fund's acquisition of such security or asset. Accordingly, any later increase or decrease resulting from a change in values, assets or other circumstances or any subsequent rating change made by a rating service (or as determined by the Adviser if the security is not rated by a rating agency) will not compel the Fund to dispose of such security or other asset. Notwithstanding the foregoing, the Fund must always be in compliance with the borrowing policies set forth above.

(iv) approve prior to appointment the engagement and, when appropriate, replacement of the independent registered public accounting firm, and, if applicable, nominate the independent registered public accounting firm to be proposed for shareholder ratification in any proxy statement of a Fund; (v) evaluate the qualifications, independence and performance of the independent registered public accounting firm and the audit partner in charge of leading the audit; and (vi) prepare, as necessary, audit committee reports consistent with the requirements of Rule 306 of Regulation S-K for inclusion in the proxy statement of a Fund.

Messrs. Hayes (Chairman), Park, Pearlman, Reamer and Ms. Stout are currently members of the Special Committee of the Board of Trustees of the Fund. The purposes of the Special Committee are to consider, evaluate and make recommendations to the Board of Trustees concerning the following matters: (i) contractual arrangements with each service provider to the Fund, including advisory, sub-advisory, transfer agency, custodial and fund accounting, distribution services and administrative services; (ii) any and all other matters in which any of the Fund service providers (including Eaton Vance or any affiliated entity thereof) has an actual or potential conflict of interest with the interests of the Fund, or investors therein; and (iii) any other matter appropriate for review by the non-interested Trustees, unless the matter is within the responsibilities of the Audit Committee or the Governance Committee of the Fund.

As of the date of this SAI, the Governance Committee has met times, the Audit Committee and Special Committee have each held meeting and the Contract Review Subcommittee has held meetings.

When considering approval of the Advisory Agreement between the Fund and the Adviser, and the Sub-Advisory Agreement between the Adviser and Rampart, the Special Committee considered, among other things, the following:

+ A report comparing the fees and expenses of the Fund and certain profitability analyses prepared by Eaton Vance and Rampart;

+ Information on the relevant peer group(s) of funds;

+ The economic outlook and the general investment outlook in the relevant investment markets;

+ Eaton Vance's and Rampart's results and financial condition and the overall organization of the Adviser and the Sub-Adviser;

+ Arrangements regarding the distribution of Fund shares;

TRUSTEES AND OFFICERS

+ The procedures used to determine the fair value of the Fund's assets;

+ The allocation of brokerage and the benefits received by the Adviser as the result of brokerage allocation; including allocations to soft dollar brokerage and allocations to firms that sell Eaton Vance fund shares;

+ Eaton Vance's management of the relationship with the custodian, subcustodians and fund accountants;

+ The resources devoted to Eaton Vance's compliance efforts undertaken on behalf of the funds it manages and the record of compliance with the investment policies and restrictions and with policies on personal securities transactions;

+ Rampart's compliance efforts with respect to the accounts it manages;

+ The quality, nature, cost and character of the administrative and other non-investment management services provided by Eaton Vance and its affiliates and of Rampart;

+ The terms of the Advisory Agreement and the Sub-Advisory Agreement, and the reasonableness and appropriateness of the particular fee paid by the Fund for the services described therein;

+ Operating expenses (including transfer agency expenses) to be paid to third parties; and

+ Information to be provided to investors, including the Fund's shareholders.

In evaluating the Advisory Agreement between the Fund and Eaton Vance, and the Sub-Advisory Agreement between the Adviser and Rampart, the Special Committee reviewed material furnished by Eaton Vance and Rampart at the initial Board meeting held on September 24, 2004, including the above referenced considerations and information relating to the education, experience and number of investment professionals and other personnel who would provide services under the Advisory Agreement and under the Sub-Advisory Agreement. The Special Committee also took into account the time and attention to be devoted by senior management to the Fund and the other funds in the complex. The Special Committee evaluated the level of skill required to manage the Fund and concluded that the human resources available at Eaton Vance were appropriate to fulfill effectively the duties of the Adviser on behalf of the Fund. The Special Committee also considered the business reputation of the Adviser, its financial resources and professional liability insurance coverage and concluded that Eaton Vance would be able to meet any reasonably foreseeable obligations under the Advisory Agreement. The Special Committee also considered the business reputation of Rampart and its options strategy and its past experience in implementing this strategy.

The Special Committee received information concerning the investment philosophy and investment process to be applied by Eaton Vance and Rampart in managing the Fund. In this regard, the Special Committee considered Eaton Vance's in-house research capabilities as well as other resources available to Eaton Vance personnel, including research services that may be available to Eaton Vance as a result of securities transactions effected for the Fund and other investment advisory clients. The Special Committee concluded that Eaton Vance's and Rampart's investment process, research capabilities and philosophy were well suited to the Fund, given the Fund's investment objective and policies.

In addition to the factors mentioned above, the Special Committee also reviewed the level of the Adviser's profits in respect of the management of the Eaton Vance funds, including the Fund. The Special Committee considered the other profits realized by Eaton Vance and its affiliates in connection with the operation of the Fund. The Special Committee also considered profit margins of Eaton Vance in comparison with available industry data. In addition, the Special Committee considered the fiduciary duty assumed by the Adviser in connection with the service rendered to the Fund and the business reputation of the Adviser, its financial resources and its professional liability insurance coverage. In


10

TRUSTEES AND OFFICERS

evaluating the fees to be paid to Rampart, the Special Committee considered and discussed fees paid to other investment sub-advisers in similar circumstances, as well as fees charged by Rampart to other clients.

The Special Committee did not consider any single factor as controlling in determining whether or not to approve the Advisory Agreement and the Sub-Advisory Agreement. Nor are the items described herein all encompassing of the matters considered by the Special Committee. In assessing the information provided by Eaton Vance and its affiliates and Rampart, the Special Committee also took into consideration the benefits to shareholders of investing in a fund that is part of a large family of funds which provides a large variety of shareholder services.

Based on its consideration of all factors that it deemed material and assisted by the advice of its independent counsel, the Special Committee concluded that the approval of the Advisory Agreement and the Sub-Advisory Agreement, including the fee structure (described herein) is in the interests of shareholders. The Special Committee also considered that the Adviser would enter into a Shareholder Services Agreement with UBS Securities LLC, whereby the Adviser (and not the Fund) would pay UBS Securities LLC to provide upon request certain market data and reports to support shareholder services pursuant to the agreement.

As of December 31, 2003, no noninterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of EVC, EVD, Rampart or any person controlling, controlled by or under common control with EVC, EVD or Rampart.

During the calendar years ended December 31, 2002 and December 31, 2003, no noninterested Trustee (or their immediate family members) had:

1. Any direct or indirect interest in Eaton Vance, EVC, EVD, Rampart or any person controlling, controlled by or under common control with EVC, EVD or Rampart;

2. Any direct or indirect material interest in any transaction or series of similar transactions with (i) the Fund; (ii) another fund managed by EVC or Rampart, distributed by EVD or a person controlling, controlled by or under common control with EVC, EVD or Rampart; (iii) EVC, EVD or Rampart; (iv) a person controlling, controlled by or under common control with EVC, EVD or Rampart; or (v) an officer of any of the above; or

3. Any direct or indirect relationship with (i) the Fund; (ii) another fund managed by EVC or Rampart, distributed by EVD or a person controlling, controlled by or under common control

with EVC, EVD or Rampart; (iii) EVC, EVD or Rampart; (iv) a person controlling, controlled by or under common control with EVC, EVD or Rampart; or (v) an officer of any of the above.

During the calendar years ended December 31, 2002 and December 31, 2003, no officer of EVC, EVD, Rampart or any person controlling, controlled by or under common control with EVC, EVD or Rampart served on the Board of Directors of a company where a noninterested Trustee of the Fund or any of their immediate family members served as an officer.

Trustees of the Fund who are not affiliated with the Adviser may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of a Trustees Deferred Compensation Plan (the "Trustees' Plan"). Under the Trustees' Plan, an eligible Trustee may elect to have his deferred fees invested by the Fund in the shares of one or more funds in the Eaton Vance Family of Funds, and the amount paid to the Trustees under the Trustees' Plan will be determined based upon the performance of such investments. Deferral of Trustees' fees in accordance with the Trustees' Plan will have a negligible effect on the Fund's assets, liabilities, and net income per share, and will not obligate the Fund to retain the services of any Trustee or obligate the Fund to pay any particular level of compensation to the Trustee. The Fund does not have a retirement plan for its Trustees.

The fees and expenses of the Trustees of the Fund are paid by the Fund. (A Trustee of the Fund who is a member of the Eaton Vance organization receives no compensation from the Fund.) For the Fund's fiscal year ending March 31, 2005, it is anticipated that the Trustees of the Fund will earn the following compensation in their capacities as Trustees. For the year ended December 31, 2003, the Trustees earned the compensation set forth below in their capacities as Trustees from the funds in the Eaton Vance fund complex(1).

PROXY VOTING POLICY. The Fund is subject to the Eaton Vance Funds Proxy Voting Policy and Procedures (the "Fund Policy"), pursuant to which the Trustees have delegated proxy voting responsibility to the Adviser and adopted the Adviser's proxy voting policies and procedures (the "Policies") which are described below. The Trustees will review the Fund's proxy voting records from time to time and will annually consider approving the Policies for the upcoming year. In the event that a conflict of interest arises between the Fund's shareholders and the Adviser or any of its affiliates or any affiliate of the Fund, the Adviser will generally refrain from voting the proxies related to the companies giving rise to such conflict until it consults with the Board of the Fund, except as contemplated under the Fund Policy. The Board's Special Committee will instruct the Adviser on the appropriate course of action.

The Policies are designed to promote accountability of a company's management to its shareholders and to align the interests of management with those shareholders. The Adviser will generally support company management on proposals relating to environmental and social policy issues, on matters regarding the state of organization of the company and routine matters related to corporate administration which are not expected to have a significant economic impact on the company or its shareholders. On all other matters, the Adviser will review each matter on a case-by-case basis and


12

TRUSTEES AND OFFICERS

reserves the right to deviate from the Policies' guidelines when it believes the situation warrants such a deviation. The Policies include voting guidelines for matters relating to, among other things, the election of directors, approval of independent auditors, executive compensation, corporate structure and anti-takeover defenses. The Adviser may abstain from voting from time to time where it determines that the costs associated with voting a proxy outweigh the benefits derived from exercising the right to vote.

In addition, the Adviser will monitor situations that may result in a conflict of interest between the Fund's shareholders and the Adviser or any of its affiliates or any affiliate of the Fund by maintaining a list of significant existing and prospective corporate clients. The Adviser's personnel responsible for reviewing and voting proxies on behalf of the Fund will report any proxy received or expected to be received from a company included on that list to members of senior management of the Adviser identified in the Policies. Such members of senior management will determine if a conflict exists. If a conflict does exist, the proxy will either be voted strictly in accordance with the Policies or the Adviser will seek instruction on how to vote from the Special Committee. Information on how the Fund voted proxies relating to portfolio securities during the 12 month period ended June 30, 2004 is available (1) without charge, upon request, by calling 1-800-262-1122, and (2) on the Securities and Exchange Commission's website at http://www.sec.gov.

Investment advisory and other services

The Investment Adviser. Eaton Vance, its affiliates and its predecessor companies have been managing assets of individuals and institutions since 1924 and of investment companies since 1931. They maintain a large staff of experienced fixed-income, senior loan and equity investment professionals to service the needs of their clients. The equity group covers stocks ranging from blue chip to emerging growth companies. Eaton Vance and its affiliates act as adviser to a family of mutual funds, and individual and various institutional accounts. The fixed-income group focuses on all kinds of taxable investment-grade and high-yield securities, tax-exempt investment-grade and high-yield securities, and U.S. government securities. The senior loan group focuses on senior floating rate loans, unsecured loans and other floating rate debt securities such as notes, bonds and asset backed securities, including corporations, hospitals, retirement plans, universities, foundations and trusts.

The Fund will be responsible for all of its costs and expenses not expressly stated to be payable by Eaton Vance under the Advisory Agreement or Administration Agreement. Such costs and expenses to be borne by the Fund include, without limitation: custody and transfer agency fees and expenses, including those incurred for determining net asset value and keeping accounting books and records; expenses of pricing and valuation services; the cost of share certificates; membership dues in investment company organizations; expenses of acquiring, holding and disposing of securities and other investments; fees and expenses of registering under the securities laws, stock exchange listing fees and governmental fees; rating agency fees and preferred share remarketing expenses; expenses of reports to shareholders, proxy statements and other expenses of shareholders' meetings; insurance premiums; printing and mailing expenses; interest, taxes and corporate fees; legal and accounting expenses; compensation and expenses of Trustees not affiliated with Eaton Vance; expenses of conducting repurchase offers for the purpose of repurchasing Fund shares; and investment advisory and administration fees. The Fund will also bear expenses incurred in connection with any litigation in which the Fund is a party and any legal obligation to indemnify its officers and Trustees with respect thereto, to the extent not covered by insurance.

The Advisory Agreement with the Adviser continues in effect to September 24, 2006 and from year to year so long as such continuance is approved at least annually (i) by the vote of a majority of the noninterested Trustees of the Fund or of the Adviser cast in person at a meeting specifically called for the purpose of voting on such approval and (ii) by the Board of Trustees of the Fund or by vote of a


13

INVESTMENT ADVISORY AND OTHER SERVICES

majority of the outstanding Shares of the Fund. The Fund's Administration Agreement continues in effect from year to year so long as such continuance is approved at least annually by the vote of a majority of the Fund's Trustees. Each agreement may be terminated at any time without penalty on sixty (60) days' written notice by the Trustees of the Fund or Eaton Vance, as applicable, or by vote of the majority of the outstanding shares of the Fund. Each agreement will terminate automatically in the event of its assignment. Each agreement provides that, in the absence of willful misfeasance, bad faith, gross negligence or reckless disregard of its obligations or duties to the Fund under such agreements on the part of Eaton Vance, Eaton Vance shall not be liable to the Fund for any loss incurred, to the extent not covered by insurance.

The Advisory Agreement provides that Eaton Vance may engage one or more investment sub-advisers to assist with some or all aspects of the management of the Fund's investments subject to such approvals as are required under the 1940 Act. Pursuant to these provisions, Eaton Vance has engaged Rampart as a sub-adviser to provide assistance with the development, implementation and execution of the Fund's options strategy. The Advisory Agreement provides that Eaton Vance may terminate any sub-advisory agreement entered into and directly assume any functions performed by the sub-adviser, upon approval of the Board of Trustees, without the need for approval of the shareholders of the Fund.

Eaton Vance is a business trust organized under Massachusetts law. EV serves as trustee of Eaton Vance. Eaton Vance and EV are subsidiaries of EVC, a Maryland corporation and publicly-held holding company. EVC through its subsidiaries and affiliates engages primarily in investment management, administration and marketing activities. The Directors of EVC are James B. Hawkes, John G. L. Cabot, Thomas E. Faust Jr., Leo I. Higdon, Jr., John M. Nelson, Vincent M. O'Reilly and Ralph Z. Sorenson. All shares of the outstanding Voting Common Stock of EVC are deposited in a voting trust, the voting trustees of which are Messrs. James B. Hawkes, Jeffrey P. Beale, Alan R. Dynner, Thomas E. Faust Jr., Thomas J. Fetter, Scott H. Page, Duncan W. Richardson, William M. Steul, Payson F. Swaffield, Michael W. Weilheimer and Wharton P. Whitaker (all of whom are officers of Eaton Vance). The voting trustees have unrestricted voting rights for the election of Directors of EVC. All of the outstanding voting trust receipts issued under said voting trust are owned by certain of the officers of BMR and Eaton Vance who are also officers, or officers and Directors of EVC and EV. As indicated under "Trustees and officers", all of the officers of the Fund (as well as Mr. Hawkes who is also a Trustee) hold positions in the Eaton Vance organization.

EVC and its affiliates and their officers and employees from time to time have transactions with various banks, including the custodian of the Fund, IBT. It is Eaton Vance's opinion that the terms and conditions of such transactions were not and will not be influenced by existing or potential custodial or other relationships between the Fund and such banks.

The Sub-Adviser. Rampart Investment Management Company ("Rampart" or "Sub-Adviser") acts as the Fund's investment sub-adviser and provides advice and assistance in pursuing the Fund's options strategy pursuant to a sub-advisory agreement between the Adviser and Rampart (the "Sub-Advisory Agreement"). Rampart, a Massachusetts corporation, was founded in 1983 by its current owners Ronald M. Egalka and David R. Fraley. The Sub-Adviser provides customized investment management services within a core competency in options to a spectrum of institutional clients. Since its inception, the Sub-Adviser has continuously expanded its computer modeling and analytical capabilities and created tools to capitalize on opportunities in the capital markets. Rampart's principal office is located at One International Place, Boston, MA 02110. As of August 31, 2004 Rampart had approximately $1 billion of assets under management.

Under the terms of the Sub-Advisory Agreement, Rampart provides advice and assistance with the development, implementation and execution of the Fund's options strategy, all subject to the supervision and direction of the Fund's Board of Trustees and the Adviser. For services rendered by Rampart under the Sub-Advisory Agreement, Eaton Vance pays Rampart a fee, payable monthly, in an annual amount equal to 0.235% of the average daily gross assets of the Fund.


14

INVESTMENT ADVISORY AND OTHER SERVICES

The Sub-Advisory Agreement continues until September 24, 2006 and from year to year thereafter if approved annually (i) by the Fund's Board of Trustees or by the holders of a majority of its outstanding voting securities and (ii) by a majority of the Trustees who are not "interested persons" (as defined in the 1940 Act) of any party to the Sub-Advisory Agreement, by vote cast in person at a meeting called for the purpose of voting on such approval. The Sub-Advisory Agreement terminates automatically on its assignment and may be terminated without penalty on 60 days written notice at the option of either the Adviser, by the Fund's Board of Trustees or by a vote of a majority (as defined in the 1940 Act) of the Fund's outstanding shares or by Rampart upon 3 months notice. As discussed above, Eaton Vance may terminate the Sub-Advisory Agreement and directly assume responsibility for the services provided by Rampart upon approval by the Board of Trustees without the need for approval of the shareholders of the Fund.

The Sub-Advisory Agreement provides that in the absence of willful misfeasance, bad faith, gross negligence or reckless disregard for its obligations and duties thereunder, the Rampart is not liable for any error or judgment or mistake of law or for any loss suffered by the Fund.

CODES OF ETHICS

The Adviser, Rampart and the Fund have adopted Codes of Ethics governing personal securities transactions. Under the Codes of Ethics, Eaton Vance and Rampart employees may purchase and sell securities (including securities held or eligible for purchase by the Fund) subject to certain pre-clearance and reporting requirements and other procedures.

The Codes of Ethics can be reviewed and copied at the Securities and Exchange Commission's public reference room in Washington, DC (call 1-202-942-8090 for information on the operation of the public reference room); on the EDGAR Database on the SEC's Internet site (http://www.sec.gov); or, upon payment of copying fees, by writing the SEC's public reference section, Washington, DC 20549-0102, or by electronic mail at publicinfo@sec.gov.

Eaton Vance will furnish to the Fund investment advice and provide related office facilities and personnel for servicing the investments of the Fund. Eaton Vance will compensate all Trustees and officers of the Fund who are members of the Eaton Vance organization and who render investment services to the Fund, and will also compensate all other Eaton Vance personnel who provide research and investment services to the Fund.

Determination of net asset value

The net asset value per share of the Fund is determined no less frequently than daily, on each day that the New York Stock Exchange (the "Exchange") is open for trading, as of the close of regular trading on the Exchange (normally 4:00 p.m. New York time). The Fund's net asset value per share is determined by IBT, in the manner authorized by the Trustees of the Fund. Net asset value is computed by dividing the value of the Fund's total assets, less its liabilities by the number of shares outstanding.

The Trustees of the Fund have established the following procedures for fair valuation of the Fund's assets under normal market conditions. Marketable securities listed on foreign or U.S. securities exchanges generally are valued at closing sale prices or, if there were no sales, at the mean between the closing bid and asked prices therefor on the exchange where such securities are principally traded (such prices may not be used, however, where an active over-the-counter market in an exchange listed security better reflects current market value). Marketable securities listed in the NASDAQ National Market System are valued at the NASDAQ official closing price. Unlisted or listed securities for which closing sale prices are not available are valued at the mean between the latest bid and asked prices. An option is valued at the last sale price as quoted on the principal exchange or board of trade on which such option or contract is traded, or in the absence of a sale, at the mean between the last bid and asked prices. When the Fund writes a call option it records the premium as an asset and equivalent liability and thereafter adjusts the liability to the market value of the option determined in accordance with the preceding sentence.

The Adviser and the Valuation Committee may implement new pricing methodologies or expand mark-to-market valuation of debt securities whose market prices are not readily available in the future, which may result in a change in the Fund's net asset value per share. The Fund's net asset value per share will also be affected by fair value pricing decisions and by changes in the market for such debt securities. In determining the fair value of a debt security, the Adviser will consider relevant factors, data, and information, including: (i) the characteristics of and fundamental analytical data relating to the debt security, including the cost, size, current interest rate, period until next interest rate reset, maturity and base lending rate of the debt security, the terms and conditions of the debt security and any related agreements, and the position of the debt security in the borrower's debt structure; (ii) the nature, adequacy and value of the collateral, including the Fund's rights, remedies and interests with respect to the collateral; (iii) the creditworthiness of the borrower, based on an evaluation of its financial condition, financial statements and information about the borrower's business, cash flows, capital structure and future prospects; (iv) information relating to the market for the debt security, including price quotations for and trading in the debt security and interests in similar debt securities and the market environment and investor attitudes towards the debt security and interests in similar debt securities;
(v) the experience, reputation, stability and financial condition of the agent and any intermediate participants in the debt security; and (vi) general economic and market conditions affecting the fair value of the debt security. The fair value of each debt security is reviewed and approved by the Adviser's Valuation Committee and the Fund's Trustees.

Debt securities for which the over-the-counter market is the primary market are normally valued on the basis of prices furnished by one or more pricing services at the mean between the latest available bid and asked prices. OTC options are valued at the mean between the bid and asked prices provided by dealers. Financial futures contracts listed on commodity exchanges and exchange-traded options are valued at closing settlement prices. Short-term obligations having remaining maturities of less than 60 days are valued at amortized cost, which approximates value, unless the Trustees determine that under particular circumstances such method does not result in fair value. As authorized by the Trustees, debt securities (other than short-term obligations) may be valued on the basis of valuations furnished by a pricing service which determines valuations based upon market transactions for normal,


16

DETERMINATION OF NET ASSET VALUE

institutional-size trading units of such securities. Securities for which there is no such quotation or valuation and all other assets are valued at fair value as determined in good faith by or at the direction of the Fund's Trustees considering relevant factors, data and information, including the market value of freely tradable securities of the same class in the principal market on which such securities are normally traded.

All other securities are valued at fair value as determined in good faith by or at the direction of the Trustees.

The daily valuation of foreign equity securities held by the Fund generally is determined as of the close of trading on the principal exchange on which such securities trade. Events occurring after the close of trading on foreign exchanges may result in adjustments to the valuation of foreign securities to more accurately reflect their fair value as of the close of regular trading on the Exchange. The Fund may rely on an independent fair valuation service in making any such adjustment. Foreign securities held by the Fund will be valued in U.S. dollars; such values will be computed by the custodian based on foreign currency exchange rate quotations supplied by an independent quotation service.


17


Portfolio trading

Decisions concerning the execution of portfolio security transactions, including the selection of the market and the executing firm, are made by Eaton Vance, the Fund's Adviser or, Rampart as the Sub-Adviser. As used below, "Adviser" refers to Eaton Vance and Rampart, as applicable. The Adviser is also responsible for the execution of transactions for all other accounts managed by it. The Adviser places the portfolio security transactions for execution with many firms. The Adviser uses its best efforts to obtain execution of portfolio security transactions at prices which are advantageous to the Fund and at reasonably competitive spreads or (when a disclosed commission is being charged) at reasonably competitive commission rates. In seeking such execution, the Adviser will use its best judgment in evaluating the terms of a transaction, and will give consideration to various relevant factors, including without limitation the full range and quality of the executing firm's services, the value of the brokerage and research services provided, the responsiveness of the firm to the Adviser, the size and type of the transaction, the nature and character of the market for the security, the confidentiality, speed and certainty of effective execution required for the transaction, the general execution and operational capabilities of the executing firm, the reputation, reliability, experience and financial condition of the firm, the value and quality of the services rendered by the firm in this and other transactions, and the reasonableness of the spread or commission, if any.

Transactions on stock exchanges and other agency transactions involve the payment of negotiated brokerage commissions. Such commissions vary among different broker-dealer firms, and a particular broker-dealer may charge different commissions according to such factors as the difficulty and size of the transaction and the volume of business done with such broker-dealer. Transactions in foreign securities often involve the payment of brokerage commissions, which may be higher than those in the United States. There is generally no stated commission in the case of securities traded in the over-the- counter markets, but the price paid or received usually includes an undisclosed dealer markup or markdown. In an underwritten offering the price paid often includes a disclosed fixed commission or discount retained by the underwriter or dealer.

Although spreads or commissions paid on portfolio security transactions will, in the judgment of the Adviser, be reasonable in relation to the value of the services provided, commissions exceeding those which another firm might charge may be paid to broker-dealers who were selected to execute transactions on behalf of the Adviser's clients in part for providing brokerage and research services to the Adviser.

As authorized in Section 28(e) of the Securities Exchange Act of 1934, as amended, a broker or dealer who executes a portfolio transaction on behalf of the Fund may receive a commission which is in excess of the amount of commission another broker or dealer would have charged for effecting that transaction if the Adviser determines in good faith that such compensation was reasonable in relation to the value of the brokerage and research services provided. This determination may be made on the basis of that particular transaction or on the basis of overall responsibilities which the Adviser and its affiliates have for accounts over which they exercise investment discretion. Brokerage and research services may include advice as to the value of securities, the advisability of investing in, purchasing, or selling securities, and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issuers, industries, securities, economic factors and trends, portfolio strategy and the performance of accounts; effecting securities transactions and performing functions incidental thereto (such as clearance and settlement); and the "Research Services" referred to in the next paragraph.

It is a common practice of the investment advisory industry and of the advisers of investment companies, institutions and other investors to receive research, analytical, statistical and quotation services, data,


18

PORTFOLIO TRADING

information and other services, products and materials which assist such advisers in the performance of their investment responsibilities ("Research Services") from broker-dealer firms which execute portfolio transactions for the clients of such advisers and from affiliates of executing broker-dealers. Advisers also commonly receive Research Services from research providers that are not affiliated with an executing broker-dealer, but which have entered into payment arrangements involving an executing broker-dealer ("Third Party Research Services"). Under a typical Third Party Research Services payment arrangement, the research provider agrees to provide services to an Adviser in exchange for specified payments to the research provider by a broker-dealer that executes portfolio transactions for clients of the Adviser. The Adviser and the executing broker-dealer enter into a related agreement specifying the amount of brokerage business the Adviser will direct to the executing broker-dealer to offset payments made by the executing broker-dealer for Third Party Research Services received by the Adviser. For example, the Adviser may agree to direct brokerage business generating $45,000 in commissions on portfolio transactions to a broker-dealer firm as consideration for the executing broker-dealer making payments of $30,000 to a provider of Third Party Research Services. The ratio of the commissions to be paid to an executing broker-dealer as consideration for Third Party Research Services over the cost borne by the executing broker-dealer in connection with providing such services to the Adviser is referred to herein as the "Third Party Research Services Payment Ratio."

Consistent with the foregoing practices, the Adviser receives Research Services from many broker-dealer firms with which the Adviser places the Fund's transactions and from third parties with which these broker-dealers have arrangements. The Fund and the Adviser may also receive Research Services from underwriters and dealers in fixed-price offerings, which Research Services are reviewed and evaluated by the Adviser in connection with its investment responsibilities.

These Research Services include such matters as general economic, political, business and market information, industry and company reviews, evaluations of securities and portfolio strategies and transactions, proxy voting data and analysis services, technical analysis of various aspects of the securities market, recommendations as to the purchase and sale of securities and other portfolio transactions, financial, industry and trade publications, news and information services, pricing and quotation equipment and services, and research oriented computer hardware, software, databases and services. Any particular Research Service obtained through a broker-dealer may be used by the Adviser in connection with client accounts other than those accounts which pay commissions to such broker-dealer. Any such Research Service may be broadly useful and of value to the Adviser in rendering investment advisory services to all or a significant portion of its clients, or may be relevant and useful for the management of only one client's account or of a few clients' accounts, or may be useful for the management of merely a segment of certain clients' accounts, regardless of whether any such account or accounts paid commissions to the broker-dealer through which such Research Service was obtained. The advisory fee paid by the Fund is not reduced because the Adviser receives such Research Services. The Adviser evaluates the nature and quality of the various Research Services obtained through broker-dealer firms and attempts to allocate sufficient portfolio security transactions to such firms to ensure the continued receipt of Research Services which the Adviser believes are useful or of value to it in rendering investment advisory services to its clients.

In the event that the Adviser executes Fund securities transactions with a broker-dealer and the associated commission is consideration for Third Party Research Services (as described above), the Adviser has agreed to reduce the advisory fee payable by the Fund by an amount equal to the commission payment associated with the transaction divided by the applicable Third Party Research Services Payment Ratio.

Some executing broker-dealers develop and make available directly to their brokerage customers proprietary Research Services ("Proprietary Research Services"). As a general matter, broker-dealers bundle the cost of Proprietary Research Services with trade execution services rather than charging


19

PORTFOLIO TRADING

separately for each. In such circumstances, the cost or other value of the Proprietary Research Services cannot be determined. The advisory fee paid by the Fund will not be reduced in connection with the receipt of Proprietary Research Services by the Adviser.

The investment companies sponsored by the Adviser or its affiliates may allocate brokerage commissions to acquire information relating to the performance, fees and expenses of such companies and other mutual funds, which information is used by the Trustees of such companies to fulfill their responsibility to oversee the quality of the services provided by various entities, including the Adviser. Such companies may also pay cash for such information.

Subject to the requirement that the Adviser shall use its best efforts to seek and execute Fund security transactions at advantageous prices and at reasonably competitive spreads or commission rates, the Adviser is authorized to consider as a factor in the selection of any broker-dealer firm with whom fund orders may be placed the fact that such firm has sold or is selling Fund shares or shares of other investment companies sponsored by the Adviser or its affiliates. This policy is not inconsistent with a rule of the NASD, which rule provides that no firm which is a member of the NASD shall favor or disfavor the distribution of shares of any particular investment company or group of investment companies on the basis of brokerage commissions received or expected by such firm from any source.

The Fund and the Adviser may also receive Research Services from underwriters and dealers in fixed-price offerings, which Research Services are reviewed and evaluated by the Adviser in connection with its investment responsibilities. The investment companies sponsored by the Adviser or its affiliates may allocate trades in such offerings to acquire information relating to the performance, fees and expenses of such companies and other mutual funds, which information is used by the Trustees of such companies to fulfill their responsibility to oversee the quality of the services provided by various entities, including the Adviser, to such companies. Such companies may also pay cash for such information.

Securities considered as investments for the Fund may also be appropriate for other investment accounts managed by the Adviser or its affiliates. Whenever decisions are made to buy or sell securities by the Fund and one or more of such other accounts simultaneously, the Adviser will allocate the security transactions (including "hot" issues) in a manner which it believes to be equitable under the circumstances. As a result of such allocations, there may be instances where the Fund will not participate in a transaction that is allocated among other accounts. If an aggregated order cannot be filled completely, allocations will generally be made on a pro rata basis. An order may not be allocated on a pro rata basis where, for example: (i) consideration is given to portfolio managers who have been instrumental in developing or negotiating a particular investment; (ii) consideration is given to an account with specialized investment policies that coincide with the particulars of a specific investment; (iii) pro rata allocation would result in odd-lot or de minimis amounts being allocated to a portfolio or other client; or (iv) where the Adviser reasonably determines that departure from a pro rata allocation is advisable. While these aggregation and allocation policies could have a detrimental effect on the price or amount of the securities available to the Fund from time to time, it is the opinion of the Trustees of the Fund that the benefits from the Adviser's organization outweigh any disadvantage that may arise from exposure to simultaneous transactions.

Taxes

The following discussion of federal income tax matters is based on the advice of Kirkpatrick & Lockhart LLP, counsel to the Fund. The Fund intends to elect to be treated and to qualify each year as a regulated investment company ("RIC") under the Internal Revenue Code of 1986, as amended (the "Code"). Accordingly, the Fund intends to satisfy certain requirements relating to sources of its income


20

TAXES

and diversification of its assets and to distribute substantially all of its net income and net short-term and long-term capital gains (after reduction by any available capital loss carryforwards) in accordance with the timing requirements imposed by the Code, so as to maintain its RIC status and to avoid paying any federal income or excise tax. To the extent it qualifies for treatment as a RIC and satisfies the above-mentioned distribution requirements, the Fund will not be subject to federal income tax on income paid to its shareholders in the form of dividends or capital gain distributions.

In order to avoid incurring a nondeductible 4% federal excise tax obligation, the Code requires that the Fund distribute (or be deemed to have distributed) by December 31 of each calendar year an amount at least equal to the sum of (i) 98% of its ordinary income for such year, (ii) 98% of its capital gain net income (which is the excess of its realized net long-term capital gain over its realized net short-term capital loss), generally computed on the basis of the one-year period ending on October 31 of such year, after reduction by any available capital loss carryforwards, and (iii) 100% of any ordinary income and capital gain net income from the prior year (as previously computed) that were not paid out during such year and on which the Fund paid no federal income tax. Under current law, provided that the Fund qualifies as a RIC for federal income tax purposes, the Fund should not be liable for any income, corporate excise or franchise tax in The Commonwealth of Massachusetts.

If the Fund does not qualify as a RIC for any taxable year, the Fund's taxable income will be subject to corporate income taxes, and all distributions from earnings and profits, including distributions of net capital gain (if any), will be taxable to the shareholder as ordinary income. In addition, in order to requalify for taxation as a RIC, the Fund may be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.

The taxation of equity options that the Fund expects to write is governed by Code Section 1234. Pursuant to Code Section 1234, the premium received by the Fund for selling a call option is not included in income at the time of receipt. If the option expires, the premium is short-term capital gain to the Fund. If the Fund enters into a closing transaction, the difference between the amount paid to close out its position and the premium received is short-term capital gain or loss. If a call option written by the Fund is exercised, thereby requiring the Fund to sell the underlying security, the premium will increase the amount realized upon the sale of the security and any resulting gain or loss will be long-term or short-term, depending upon the holding period of the security. With respect to a put or call option that is purchased by the Fund, if the option is sold, any resulting gain or loss will be a capital gain or loss, and will be short-term or long-term, depending upon the holding period for the option. If the option expires, the resulting loss is a capital loss and is short-term or long-term, depending upon the holding period for the option. If the option is exercised, the cost of the option, in the case of a call option, is added to the basis of the purchased security and, in the case of a put option, reduces the amount realized on the underlying security in determining gain or loss. Because the Fund does not have control over the exercise of the call options it writes, such exercise or other required sales of the underlying securities may cause the Fund to realize capital gains or losses at inopportune times.

Under the "Jobs and Growth Tax Relief Reconciliation Act of 2003" (the "Tax Act"), certain income distributions paid by the Fund (whether paid in cash or reinvested in additional Fund Shares) to individual taxpayers are taxed at rates applicable to net long-term capital gains (15%, or 5% for individuals in the 10% or 15% tax brackets). This tax treatment applies only if certain holding period requirements and other requirements are satisfied by the Common Shareholder and the dividends are attributable to qualified dividend income received by the Fund itself. For this purpose, "qualified dividend income" means dividends received by the Fund from United States corporations and "qualified foreign corporations," provided that the Fund satisfies certain holding period and other requirements in respect of the stock of such corporations. These special rules relating to the taxation of ordinary income dividends paid by RICs generally apply to taxable years beginning after


21

TAXES

December 31, 2002 and beginning before January 1, 2009. Thereafter, the Fund's dividends, other than capital gain dividends, will be fully taxable at ordinary income tax rates unless further Congressional action is taken. There can be no assurance as to what portion of the Fund's dividend distributions will qualify for favorable treatment under the Tax Act.

The Fund will inform shareholders of the source and tax status of all distributions promptly after the close of each calendar year.

The benefits of the reduced tax rates applicable to long-term capital gains and qualified dividend income may be impacted by the application of the alternative minimum tax to individual shareholders.

The Fund's investment in zero coupon, payment in kind and certain other securities will cause it to realize income prior to the receipt of cash payments with respect to these securities. Such income will be accrued daily by the Fund and, in order to avoid a tax payable by the Fund, the Fund may be required to liquidate securities that it might otherwise have continued to hold in order to generate cash so that the Fund may make required distributions to its shareholders.

Investments in lower rated or unrated securities may present special tax issues for the Fund to the extent that the issuers of these securities default on their obligations pertaining thereto. The Code is not entirely clear regarding the federal income tax consequences of the Fund's taking certain positions in connection with ownership of such distressed securities.

Any recognized gain or income attributable to market discount on long-term debt obligations (i.e., obligations with a term of more than one year except to the extent of a portion of the discount attributable to original issue discount) purchased by the Fund is taxable as ordinary income. A long-term debt obligation is generally treated as acquired at a market discount if purchased after its original issue at a price less than (i) the stated principal amount payable at maturity, in the case of an obligation that does not have original issue discount or (ii) in the case of an obligation that does have original issue discount, the sum of the issue price and any original issue discount that accrued before the obligation was purchased, subject to a de minimis exclusion.

The Fund's transactions in futures contracts and options will be subject to special provisions of the Code that, among other things, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital, or short-term or long-term), may accelerate recognition of income to the Fund and may defer Fund losses. These rules could, therefore, affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require the Fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out), and (b) may cause the Fund to recognize income without receiving cash with which to make distributions in amounts necessary to satisfy the 90% distribution requirement for qualifying to be taxed as a regulated investment company and the 98% distribution requirement for avoiding excise taxes. The Fund will monitor its transactions, will make the appropriate tax elections and will make the appropriate entries in its books and records when it acquires any futures contract, option or hedged investment in order to mitigate the effect of these rules and prevent disqualification of the Fund from being taxed as a regulated investment company.

In particular, the Fund expects to write call options with respect to certain securities held by the Fund. Depending on whether such options are exercised or lapse, or whether the securities or options are sold, the existence of these options will affect the amount and timing of the recognition of income and whether the income qualifies as long-term capital gain.

Further, the Fund's transactions in options are subject to special and complex federal income tax provisions that may, among other things, (i) convert dividends that would otherwise constitute qualified dividend income into short-term capital gain or ordinary income taxed at the higher rate applicable to ordinary income, (ii) treat dividends that would otherwise be eligible for the corporate


22

TAXES

dividends received deduction as ineligible for such treatment, (iii) disallow, suspend or otherwise limit the allowance of certain losses or deductions, (iv) convert long-term capital gain into short-term capital gain or ordinary income,
(v) convert an ordinary loss or deduction into a capital loss (the deductibility of which is more limited) and (vi) cause the Fund to recognize income or gain without a corresponding receipt of cash.

Any loss realized upon the sale or exchange of Fund shares with a holding period of six months or less will be treated as a long-term capital loss to the extent of any capital gain distributions received with respect to such shares. In addition, all or a portion of a loss realized on a sale or other disposition of Fund shares may be disallowed under "wash sale" rules to the extent the shareholder acquires other shares of the same Fund (whether through the reinvestment of distributions or otherwise) within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the Common Shares. Any disallowed loss will result in an adjustment to the shareholder's tax basis in some or all of the other shares acquired.

Sales charges paid upon a purchase of shares cannot be taken into account for purposes of determining gain or loss on a sale of the shares before the 91st day after their purchase to the extent a sales charge is reduced or eliminated in a subsequent acquisition of shares of the Fund (or of another fund) pursuant to the reinvestment or exchange privilege. Any disregarded amounts will result in an adjustment to the shareholder's tax basis in some or all of any other shares acquired.

Dividends and distributions on the Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when the Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when the Fund's net asset value also reflects unrealized losses. Certain distributions declared in October, November or December and paid in the following January will be taxed to shareholders as if received on December 31 of the year in which they were declared. In addition, certain other distributions made after the close of a taxable year of the Fund may be "spilled back" and treated as paid by the Fund (except for purposes of the non- deductible 4% federal excise tax) during such taxable year. In such case, shareholders will be treated as having received such dividends in the taxable year in which the distributions were actually made.

Dividends and interest received, and gains realized, by the Fund on foreign securities may be subject to income, withholding or other taxes imposed by foreign countries and U.S. possessions (collectively "foreign taxes") that would reduce the return on its securities. Tax conventions between certain countries and the United States, however, may reduce or eliminate foreign taxes, and many foreign countries do not impose taxes on capital gains in respect of investments by foreign investors. If more than 50% of the value of the Fund's total assets at the close of its taxable year consists of securities of foreign issuers, the Fund will be eligible to, and may, file an election with the Internal Revenue Service (the "Service") that will enable its shareholders, in effect, to receive the benefit of the foreign tax credit with respect to any foreign taxes paid by it. Pursuant to the election, the Fund would treat those taxes as dividends paid to its shareholders and each shareholder (1) would be required to include in gross income, and treat as paid by such shareholder, a proportionate share of those taxes, (2) would be required to treat such share of those taxes and of any dividend paid by the Fund that represents income from foreign or U.S. possessions sources as such shareholder's own income from those sources, and (3) could either deduct the foreign taxes deemed paid in computing taxable income or, alternatively, use the foregoing information in calculating the foreign tax credit against federal income tax. The Fund will report to its shareholders shortly after each taxable year their respective shares of foreign taxes paid and the income from sources within, and taxes paid to, foreign countries and U.S. possessions if it makes this election. An individual who has no more than $300 ($600 for married

TAXES

persons filing jointly) of creditable foreign taxes included on Forms 1099 and all of whose foreign source income is "qualified passive income" may elect each year to be exempt from the complicated foreign tax credit limitation, in which event such individual would be able to claim a foreign tax credit without needing to file the detailed Form 1116 that otherwise is required.

The Fund may invest in the stock of "passive foreign investment companies" ("PFICs"). A PFIC is any foreign corporation (with certain exceptions) that, in general, meets either of the following tests: (1) at least 75% of its gross income is passive or (2) an average of at least 50% of its assets produce, or are held for the production of, passive income. Under certain circumstances, the Fund will be subject to federal income tax on a portion of any "excess distribution" received on the stock of a PFIC or of any gain from disposition of that stock (collectively "PFIC income"), plus interest thereon, even if the Fund distributes the PFIC income as a taxable dividend to its shareholders. The balance of the PFIC income will be included in the Fund's investment company taxable income and, accordingly, will not be taxable to it to the extent it distributes that income to its shareholders.

If the Fund invests in a PFIC and elects to treat the PFIC as a "qualified electing fund" ("QEF"), then in lieu of the foregoing tax and interest obligation, the Fund will be required to include in income each year its pro rata share of the QEF's annual ordinary earnings and net capital gain--which it may have to distribute to satisfy the distribution requirement and avoid imposition of the excise tax--even if the QEF does not distribute those earnings and gain to the Fund. In most instances it will be very difficult, if not impossible, to make this election because of certain of its requirements.

The Fund may elect to "mark to market" its stock in any PFIC.
"Marking-to-market," in this context, means including in ordinary income each taxable year the excess, if any, of the fair market value of a PFIC's stock over the Fund's adjusted basis therein as of the end of that year. Pursuant to the election, the Fund also would be allowed to deduct (as an ordinary, not capital, loss) the excess, if any, of its adjusted basis in PFIC stock over the fair market value thereof as of the taxable year-end, but only to the extent of any net mark-to-market gains (reduced by any prior deductions) with respect to that stock included by the Fund for prior taxable years under the election. The Fund's adjusted basis in each PFIC's stock with respect to which it has made this election will be adjusted to reflect the amounts of income included and deductions taken thereunder.

Amounts paid by the Fund to individuals and certain other shareholders who have not provided the Fund with their correct taxpayer identification number ("TIN") and certain certifications required by the Service as well as shareholders with respect to whom the Fund has received certain information from the Service or a broker may be subject to "backup" withholding of federal income tax arising from the Fund's taxable dividends and other distributions as well as the gross proceeds of sales of shares, at a rate of 28% for amounts paid during 2004. An individual's TIN is generally his or her social security number. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from payments made to a shareholder may be refunded or credited against such shareholder's federal income tax liability, if any, provided that the required information is furnished to the Service.

The foregoing briefly summarizes some of the important federal income tax consequences to Common Shareholders of investing in Common Shares, reflects the federal tax law as of the date of this Statement of Additional Information, and does not address special tax rules applicable to certain types of investors, such as corporate and foreign investors. Unless otherwise noted, this discussion assumes that an investor is a U.S. shareholder and holds Common Shares as a capital asset. This discussion is based upon present provisions of the Code, the regulations promulgated thereunder, and judicial and administrative ruling authorities, all of which are subject to change or differing interpretations by the courts or the Service retroactively or prospectively. Investors should consult their tax advisors regarding other federal, state or local tax considerations that may be applicable to their particular circumstances, as well as any proposed tax law changes.

Other information

The Fund is an organization of the type commonly known as a "Massachusetts business trust." Under Massachusetts law, shareholders of such a trust may, in certain circumstances, be held personally liable as partners for the obligations of the trust. The Declaration of Trust contains an express disclaimer of shareholder liability in connection with the Fund property or the acts, obligations or affairs of the Fund. The Declaration of Trust in coordination with the Fund's By-laws also provides for indemnification out of the Fund property of any shareholder held personally liable for the claims and liabilities to which a shareholder may become subject by reason of being or having been a shareholder. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which the Fund itself is unable to meet its obligations. The Fund has been advised by its counsel that the risk of any shareholder incurring any liability for the obligations of the Fund is remote.

The Declaration of Trust provides that the Trustees will not be liable for errors of judgment or mistakes of fact or law; but nothing in the Declaration of Trust protects a Trustee against any liability to the Fund or its shareholders to which he or she would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his or her office. Voting rights are not cumulative, which means that the holders of more than 50% of the shares voting for the election of Trustees can elect 100% of the Trustees and, in such event, the holders of the remaining less than 50% of the shares voting on the matter will not be able to elect any Trustees.

The Declaration of Trust provides that no person shall serve as a Trustee if shareholders holding two-thirds of the outstanding shares have removed him from that office either by a written declaration filed with the Fund's custodian or by votes cast at a meeting called for that purpose. The Declaration of Trust further provides that the Trustees of the Fund shall promptly call a meeting of the shareholders for the purpose of voting upon a question of removal of any such Trustee or Trustees when requested in writing to do so by the record holders of not less than 10 per centum of the outstanding shares.

The Fund's Prospectus and this SAI do not contain all of the information set forth in the Registration Statement that the Fund has filed with the SEC. The complete Registration Statement may be obtained from the SEC upon payment of the fee prescribed by its Rules and Regulations.

Notes to financial statements

NOTE 1: ORGANIZATION

The Eaton Vance Enhanced Equity Income Fund (the "Fund") was organized as a Massachusetts business trust on August 11, 2004, and has been inactive since that date except for matters relating to its organization and registration as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended, and the Securities Act of 1933, as amended, and the sale of 5,000 common shares to Eaton Vance Management, the Fund's Investment Adviser.

Eaton Vance Management, or an affiliate, has agreed to reimburse all organizational costs, estimated at approximately $7,500.

Eaton Vance Management, or an affiliate, has agreed to pay all offering costs (other than sales loads) that exceed $0.04 per common share. Based on an offering size of $250,000,000 the Fund has estimated the cost of the offering to be approximately $500,000 all of which would be paid by the Fund. Any amount in excess of $500,000 would be paid by Eaton Vance Management.

The Fund's primary investment objective is to provide current income, with a secondary objective of capital appreciation. The Fund will pursue its investment objectives by investing primarily in a portfolio of large- and mid- capitalization common stocks, seeking to invest primarily in companies with above-average growth and financial strength. Under normal market conditions, the Fund will seek to generate current earnings from option premiums by selling covered call options on a substantial portion of its portfolio securities. There can be no assurance that the Fund will achieve its investment objectives.

NOTE 2: ACCOUNTING POLICIES

The Fund's financial statements are prepared in accordance with accounting principles generally accepted in the United States of America which require the use of management estimates. Actual results may differ from those estimates.

The Fund's share of offering costs will be recorded within paid in capital as a reduction of the proceeds from the sale of common shares upon the commencement of Fund operations. The offering costs reflected above assume the sale of 12,500,000 common shares.

NOTE 3: INVESTMENT MANAGEMENT AGREEMENT

ITEM 28. NUMBER OF HOLDERS OF SECURITIES

Set forth below is the number of record holders as of October 21, 2004, of each class of securities of the Registrant:

Title of Class                                         Number of Record Holders

interest, par value $0.01 per share

ITEM 29. INDEMNIFICATION

The Registrant's By-Laws filed in the Registrant's Initial Common Shares Registration Statement and the form of Underwriting Agreement filed in Pre-Effective Amendment No. 1 contain provisions limiting the liability, and providing for indemnification, of the Trustees and officers under certain circumstances.

Registrant's Trustees and officers are insured under a standard investment company errors and omissions insurance policy covering loss incurred by reason of negligent errors and omissions committed in their official capacities as such. Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the "Securities Act"), may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described in this Item 29, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

ITEM 30. BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER

Reference is made to: (i) the information set forth under the caption Investment advisory and other services" in the Statement of Additional Information; (ii) the Eaton Vance Corp. 10-K filed under the Securities Exchange Act of 1934 (File No. 001-8100); (iii) the Form ADV of Eaton Vance Management (File No. 801-15930); and (iv) the Form ADV of Rampart Investment Management Company, Inc.
