EATON VANCE TAX-MANAGED BUYWRITE INCOME FUND

COMMON SHARES

INVESTMENT OBJECTIVES. Eaton Vance Tax-Managed BuyWrite 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 and gains, with a secondary objective of capital appreciation. In pursuing its investment objectives, the Fund will evaluate returns on an after-tax basis, seeking to reduce and defer shareholder taxes.

Under normal market conditions, the Fund's investment program will consist primarily of (1) owning a diversified portfolio of common stocks that seeks to approximate the pretax investment performance of the S&P Composite Stock Price Index (the "S&P 500") and (2) selling S&P 500 index call options on a continuous basis on substantially the full value of its holdings of common stocks. The Fund will seek to approximate the pretax investment performance of the CBOE S&P 500 BuyWrite Index (the "BXM") and to achieve higher after-tax returns than a pure replication of the BXM strategy by employing a number of tax-management techniques and strategies. The BXM is a passive stock-plus-covered-call index created and maintained by the Chicago Board Options Exchange (the "CBOE").

INVESTMENT ADVISER AND SUB-ADVISER. The Fund's investment adviser is Eaton Vance Management ("Eaton Vance" or the "Adviser"). As of October 31, 2004, Eaton Vance and its subsidiaries managed approximately $[__] billion on behalf of funds, institutional clients and individuals, including approximately $[__] billion in equity fund assets. Eaton Vance has engaged its affiliate Parametric Portfolio Associates LLC ("Parametric" or the "Sub-Adviser") as a sub-adviser to the Fund. Parametric, founded in 1987, specializes in managing broadly diversified, risk controlled and tax-efficient portfolios for institutional, high net worth investors and investment company clients and their advisers. Parametric managed approximately $[__] billion in assets as of October 31, 2004. Eaton Vance will be responsible for managing the Fund's overall investment program, implementing the Fund's index options strategy, providing research support to the Sub-Adviser and supervising the performance of the Sub-Adviser. The Sub-Adviser will be responsible for structuring and managing the Fund's common stock portfolio, including tax-loss harvesting and other tax-management techniques. The Sub-Adviser has developed specialized programs and systems that allow for efficient implementation of the Fund's strategies.

PORTFOLIO CONTENTS. Under normal market conditions, the Fund will invest its managed assets in a diversified portfolio of common stocks that seeks to approximate the pre-tax total return performance of the S&P 500. Due to tax considerations, the Fund intends to limit the overlap between its stock portfolio holdings (and any subset thereof) and the S&P 500 to less than 70% at all times. The Fund will utilize portfolio optimization systems and software to seek to minimize the "tracking error" of its stock portfolio's projected performance versus that of the S&P 500. The Fund will invest primarily in common stocks of U.S. issuers. (CONTINUED ON INSIDE FRONT COVER)

(1) Eaton Vance (not the Fund) will pay certain additional compensation to qualifying underwriters. See "Underwriting." Eaton Vance (not the Fund) will pay [__] for services provided pursuant to a shareholder servicing agreement between [__] and Eaton Vance. See "Underwriting." The total compensation received by the Underwriters will not exceed [__]% of the aggregate initial offering price of the Common Shares offered hereby.

In addition to the sales load, the Fund will pay offering expenses of up to $[__] per share, estimated to total $[__], which will reduce the "Proceeds to Fund" (above). Eaton Vance or an affiliate has agreed to pay the amount by which the aggregate of all of the Fund's offering costs (other than sales loads) exceeds $[__] per share. Eaton Vance or an affiliate has agreed to reimburse all Fund organizational costs.

Under normal market conditions, the Fund will seek to generate current earnings by employing an options strategy of writing (selling) index call options on the S&P 500. The Fund expects to sell index call options on a continuous basis on substantially the full value of its holdings of common stocks. Writing index call options involves a tradeoff between the option premiums received and reduced participation in potential future stock price appreciation of the Fund's portfolio of common stocks. Generally, the Fund intends to sell S&P 500 call options that are slightly "out-of-the-money," meaning that option exercise prices generally will be slightly higher than the current level of the index at the time the options are written. The Fund seeks to generate current earnings from option premiums and, to a lesser extent, from dividends on stocks held.

EXCHANGE LISTING. The Fund intends to apply for listing of its common shares on the New York Stock Exchange under the symbol "[ ]." 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 Tax-Managed BuyWrite Income Fund (the "Fund") is a newly organized, diversified, closed-end management investment company. The Fund seeks to achieve current income and gains with the potential for capital appreciation. Investments are based on Eaton Vance Management's ("Eaton Vance" or the "Adviser") and Parametric Portfolio Associates LLP's ("Parametric" or the "Sub-Adviser") internal research and proprietary modeling techniques and software, which are generally not available to individual investors. 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 [ ], [ ] and
[ ]. 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 $[ ] per share. The minimum purchase in this offering is 100 Shares ($ ). 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 and gains, with a secondary objective of capital appreciation. In pursuing its investment objectives, the Fund will evaluate returns on an after-tax basis, seeking to reduce and defer shareholder taxes. There can be no assurance that the Fund will achieve its investment objectives.

Under normal market conditions, the Fund's investment program will consist primarily of (1) owning a diversified portfolio of common stocks that seeks to approximate the pretax investment performance of the S&P Composite Stock Price Index (the "S&P 500") and (2) selling S&P 500 index call options on a continuous basis on substantially the full value of its holdings of common stocks. The Fund will seek to approximate the pretax investment performance of the CBOE S&P 500 BuyWrite Index (the "BXM") and to achieve higher after-tax returns than a pure replication of the BXM strategy by employing a number of tax-management techniques and strategies. The BXM is a passive stock-plus-covered-call index created and maintained by the Chicago Board Options Exchange (the "CBOE").

Under normal market conditions, the Fund will invest its managed assets in a diversified portfolio of common stocks that seeks to approximate the pretax total return performance of the S&P 500. Due to tax considerations, the Fund intends to limit the overlap between its stock portfolio holdings (and any subset thereof) and the S&P 500 to less than 70% at all times. The Fund will utilize portfolio optimization systems and software to seek to minimize the "tracking error" of its stock portfolio's projected performance versus that of the S&P 500. The Fund will invest primarily in common stocks of U.S. issuers. 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"). The Fund normally expects that its assets 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.

Under normal market conditions, the Fund will seek to generate current earnings by employing an options strategy of writing (selling) S&P 500 index call options on a continuous basis on substantially the full value of its holdings of common stocks. Writing index call options involves a tradeoff between the option premiums received and reduced participation in potential future stock price appreciation. Generally, the Fund intends to sell S&P 500 call options that are slightly "out-of-the-money," meaning that option exercise prices generally will be slightly higher than the current level of the index at the time the options are written. The Fund seeks to generate current earnings from option premiums and, to a lesser extent, from dividends on stocks held.

1

The Fund intends to sell S&P 500 call options that are exchange-listed and "European style," meaning that the options may be exercised only on the expiration date of the option. Index options differ from options on individual securities in that index options (i) are settled in cash rather than by delivery of securities and (ii) reflect price fluctuations in a group of securities or segments of the securities market rather than price fluctuations in a single security.

As the seller of S&P 500 index call options, the Fund will receive cash (the premiums) from options purchasers. The purchaser of an S&P 500 index option has the right to any appreciation in the value of the S&P 500 over a fixed price (the exercise price) as of a specified date in the future (the expiration date). Generally, the Fund intends to sell S&P 500 call options that are slightly "out-of-the-money" (i.e., the exercise price generally will be slightly above the current level of the S&P 500 when the option is sold). The Fund will, in effect, sell the potential appreciation in the value of the S&P 500 above the exercise price in exchange for the option premium received. If, at expiration, an S&P 500 index call option sold by the Fund is exercised, the Fund will pay the purchaser the difference between the cash value of the S&P 500 and the exercise price of the option. The premium, the exercise price and the market value of the S&P 500 will determine the gain or loss realized by the Fund as the seller of the index call option.

In implementing the Fund's investment strategy, the Adviser and Sub-Adviser intend to employ a variety of techniques and strategies designed to minimize and defer the federal income taxes incurred by shareholders in connection with their investment in the Fund as described below.

The S&P 500 is an unmanaged index of 500 stocks maintained and published by Standard & Poor's that is market-capitalization weighted and generally representative of the performance of larger stocks traded in the U.S. It is not possible to invest directly in the S&P 500. The BXM is a passive total return index based on holding the stocks in the S&P 500 and selling a series of one-month S&P 500 index call options on the full value of the portfolio. The options are sold at the nearest available exercise price above the prevailing S&P 500 level (i.e., slightly out of the money). The short option position is maintained until expiration, at which time a new one-month call option is written. It is not possible to invest directly in the BXM. The Fund is not sponsored, endorsed, sold or promoted by the CBOE, and the CBOE makes no representation regarding the advisability of investing in the Fund.

INVESTMENT STRATEGY

Eaton Vance will be responsible for managing the Fund's overall investment program, implementing the Fund's index options strategy, providing research support to the Sub-Adviser and supervising the performance of the Sub-Adviser. The Sub-Adviser will be responsible for structuring and managing the Fund's common stock portfolio, including tax-loss harvesting and other tax-management techniques. The Sub-Adviser has developed specialized programs and systems that allow for efficient implementation of the Fund's strategies. The Fund's investments are actively managed, and securities may be bought or sold on a daily basis.

The Adviser believes that a strategy of owning a portfolio of common stocks and selling covered call options (a "buy-write strategy") can provide high current income and gains and attractive risk-adjusted returns. Compared to selling call options on individual stocks, selling index call options can achieve better tax and transactional efficiency because index options are cash-settled "section 1256 contracts" subject to favorable tax treatment and because the markets for index options are generally deeper and more liquid than options on individual stocks.

Eaton Vance further believes that a strategy of owning a portfolio of common stocks whose performance approximates that of the S&P 500 in conjunction with writing index call options on the S&P 500 should generally provide returns that are superior to owning the same stocks without an associated call option writing program 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 buy-write strategy generally be expected to underperform the stock only portfolio. 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 do not materially exceed the long-term historical average of stock market returns.

The Fund will seek to achieve performance from its common stock portfolio that approximates the performance of the S&P 500. To avoid being subject to the "straddle rules" under federal income tax law, the Fund intends to maintain an overlap of less than 70% between its stock portfolio (or any subset thereof) and the S&P 500 on an ongoing basis. The Fund will utilize portfolio optimization systems and software to seek to minimize the "tracking error" of its stock portfolio's projected performance versus that of the S&P 500. The Sub-Adviser will consider a variety of factors in constructing and maintaining the Fund's stock portfolio, including, but not limited to, the overlap between stock portfolio holdings and the S&P 500, the tracking error of the portfolio versus the S&P 500 and stock performance ratings as determined by the Adviser. The

2

Adviser's evaluation of the future performance potential of individual stocks will be one among several considerations in portfolio construction and will not, on a standalone basis, be determinative of portfolio construction. The Adviser's stock ratings will be based primarily on fundamental research.

The Fund's index option strategy is designed to produce current cash flow from options premiums and to moderate the volatility of the Fund's returns. This index option strategy is of a hedging nature, and is not designed to speculate on equity market performance.

The Fund expects to sell index call options on a continuous basis on substantially the full value of its holdings of common stocks. The Adviser does not intend to sell index call options representing amounts greater than the value of the Fund's common stock portfolio (i.e., take a 'naked' position). The Adviser intends to sell S&P 500 index options that are exchange-listed and "European style," meaning that the options may only be exercised on the expiration date of the option. Exchange-traded index options are settled in cash and provide that the holder of the option has the right to receive an amount of cash determined by the excess of the index value on the expiration date over the exercise price of the option. Generally, the Adviser intends to sell S&P 500 call options that are slightly "out-of-the-money," meaning that option exercise prices generally will be slightly above the current level of the index at the time the options are written. The Adviser intends to follow an options strategy similar to that of the BXM, selling primarily S&P 500 index call options with a remaining maturity of approximately one month and maintaining its short call options positions until their expiration date, at which time replacement call option positions with a remaining maturity of approximately one month are written.

In implementing the Fund's investment strategy, the Adviser and Sub-Adviser intend to employ a variety of techniques and strategies designed to minimize and defer the federal income taxes incurred by Common Shareholders in connection with their investment in the Fund. These include: (1) selling index call options that qualify for treatment as "section 1256 contracts" on which capital gains and losses are generally treated as 60% long-term and 40% short-term, regardless of holding period; (2) limiting the overlap of the Fund's stock portfolio versus the S&P 500 to less than 70% so that the Fund's stock holdings and S&P 500 index call options are not subject to the "straddle rules;" (3) engaging in a systematic program of tax-loss harvesting in the Fund's stock portfolio, periodically selling stock positions that have depreciated in value to realize capital losses that can be used to offset capital gains realized by the Fund; and (4) minimizing the sale of appreciated stock positions to reduce realized capital gains. When an appreciated security is sold, the Fund intends to select for sale the share lots resulting in the most favorable tax treatment, generally those with holding periods sufficient to qualify for long-term capital gains treatment that have the highest cost basis.

In addition, the Fund will seek to earn and distribute "qualified dividend income." Under federal income tax law enacted in 2003, the qualified dividend income of individuals and other noncorporate taxpayers is taxed at long-term capital gain tax rates if certain holding period and other requirements are met. Qualified dividends are dividends from domestic corporations and dividends from foreign corporations that meet certain specified criteria. The Fund generally can pass the tax treatment of qualified dividend income it receives through to Common Shareholders. For the Fund to receive tax-advantaged treatment of its qualified dividend income, the Fund must hold stock paying qualified dividends for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date (or more than 90 days during the associated 181-day period, in the case of certain preferred stocks). In addition, the Fund cannot be obligated to make related payments (pursuant to a short sale or otherwise) with respect to positions in any security that is substantially similar or related property with respect to such stock. Similar provisions apply to each Common Shareholder's investment in the Fund. In order for qualified dividend income paid by the Fund to a Common Shareholder to be taxable at long-term capital gains rates, the Common Shareholder must hold his or her Fund shares for more than 60 days during the 121-day period surrounding the ex-dividend date. The provisions of the Code applicable to qualified dividend income are effective through 2008. Thereafter, qualified dividend income will be subject tax at ordinary income rates unless further legislative action is taken

The Fund may seek to enhance the level of tax-advantaged dividend income it receives by emphasizing higher-yielding stocks in its stock portfolio and by engaging in dividend capture trading. In a dividend capture trade, the Fund sells a stock on or shortly after the stock's ex-dividend date and used the sale proceeds to purchase one or more other stocks that are expected to pay dividends before the next dividend payment on the stock being sold. Through this practice, the Fund may receive more dividend payments over a given time period than if it held a single stock. In order for dividends received by the Fund to qualify for favorable tax treatment, the Fund must comply with the holding period and other requirements set forth in the preceding paragraph. The use of dividend capture trading strategies will expose the Fund to increased trading costs and potentially higher short-term gain or loss.

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 intends to apply for listing of its Common Shares on the New York Stock Exchange under the symbol "[__]."

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 $[__] billion on behalf of funds, institutional clients and individuals as of October 31, 2004, including approximately [$__] billion in equity fund assets. [Twenty-nine] of the funds managed by Eaton Vance are closed-end funds. Eaton Vance has engaged Parametric, an indirect, majority-owned subsidiary of Eaton Vance Corp., as a sub-adviser to the Fund. Parametric, founded in 1987, specializes in managing broadly diversified, risk controlled and tax-efficient portfolios for institutional, high net worth investors and investment company clients and their advisers. Parametric managed approximately $[__] billion in assets as of October 31, 2004. Eaton Vance will be responsible for managing the Fund's overall investment strategy, setting the Fund's index options strategy and executing options transactions and supervising the performance of the Sub-Adviser. The Sub-Adviser will be responsible for structuring and managing the Fund's common stock portfolio, including tax-loss harvesting and other tax-management techniques. The Sub-Adviser has developed specialized programs and systems that allow for efficient implementation of the Fund's strategies. See "Management of the Fund."

DISTRIBUTIONS

Commencing with the Fund's first distribution, the Fund intends to make regular quarterly distributions to Common Shareholders sourced from the Fund's cash available for distribution. "Cash available for distribution" will consist of the Fund's net option premiums, net realized and unrealized gains on stock investments, and dividends and interest income, after payment of 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 [60-90] days and paid approximately [90-120] days after the completion of this offering, depending on market conditions.

The Fund's annual distributions 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. To the extent that that Fund's net investment income for any year exceeds the total quarterly 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. Over time, all of the Fund's investment company taxable income will be distributed.

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) or, alternatively, to retain all or a portion of the year's net capital gain and pay federal income tax on the retained gain. As provided under federal tax law, Common Shareholders of record as of the end of the Fund's taxable year will include their attributable share of the retained gain in their income for the year as a long-term capital gain, and will be entitled to a tax credit or refund for the tax deemed paid on their behalf by the Fund. The Fund may treat the cash value of tax credit and refund amounts in connection with retained capital gains as a substitute for equivalent cash distributions.

If the Fund's total quarterly distributions in any year exceed the amount of its net investment income and net capital gain dividends 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 distribution. As a result, the distributions paid by the Fund for any particular quarter may be more or less than the amount of cash available for distribution from that quarterly period. In certain circumstances, the Fund may be required to sell a portion of its investment portfolio to fund distributions. Distributions will reduce the Common Shares' net asset value.

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 (generally once per taxable year). In the event that such an exemptive order is obtained, the Fund will consider increasing the frequency of its regular distributions from quarterly to monthly.

4

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 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, may from time to time review possible actions to reduce trading discounts in the Common Shares. 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 these or other actions or that, if undertaken, such actions would result in the Common Shares trading at a price equal to or close to their net asset value. 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. Because the Fund intends to sell index call options on a continuous basis on substantially the full value of its common stock holdings, the Fund's appreciation potential from equity market performance will be limited. 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

Under normal market conditions, the Fund will invest its managed assets in a diversified portfolio of common stocks. 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 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 stocks 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.

RISK OF SELLING INDEX CALL OPTIONS

The Fund expects to sell S&P 500 index call options on a continuous basis on substantially the full value of its holdings of common stocks. The purchaser of an index call option has the right to any appreciation in the value of the index over the exercise price of the call option on the expiration date. Because their exercise is settled in cash, sellers of index call options such as the Fund cannot provide in advance for their potential settlement obligations by acquiring and holding the underlying securities. The Fund intends to mitigate the risks of its written index call positions by holding a diversified portfolio of stocks similar to those on which the S&P 500 is based. However, the Fund does not intend to acquire and hold a portfolio containing exactly the same stocks as the S&P 500 and, as a result, bears the risk that the performance of the securities held by the Fund will vary from the performance of the S&P 500. Index options written by the Fund will be priced on a daily basis. Their value will be affected primarily by changes in the price and dividend rates of the underlying common stocks in the S&P 500, changes in actual or perceived volatility of the S&P 500 and the remaining time to the options' expiration. The trading price of S&P 500 index options will also be affected by liquidity considerations and the balance of purchase and sale orders.

A decision as to whether, when and how to use options involves the exercise of skill and judgment, and even a well-conceived and well-executed options program may be adversely affected by market behavior or unexpected events. As the writer of S&P 500 index call options, the Fund will forgo, during the option's life, the opportunity to profit from increases in the value of the S&P 500 above the sum of the option premium received and the exercise price of the call option, but retains the risk of loss, minus the option premium received, should the value of the S&P 500 decline. When a call option is exercised, the Fund will be required to deliver an amount of cash determined by the excess of the value of S&P 500 at contract termination over the exercise price of the option. Thus, the sale of index call options may require the Fund to sell portfolio securities to generate cash at inopportune times or for unattractive prices.

The trading price 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 a call option position by buying 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 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.

6

The hours of trading for options may not conform to the hours during which common stocks held by the Fund are traded. To the extent that the options markets close before the markets for securities, significant price and rate movements can take place in the securities markets that would not be reflected concurrently in the options markets. Index call options are marked to market daily and their value is substantially affected by changes in the value of and dividend rates of the underlying index, changes in interest rates, changes in the actual or perceived volatility of the associated index and the remaining time to the options' expiration, as well as trading conditions in the options market.

TAX RISK

Reference is made to "Federal Income Tax Matters" for an explanation of the federal income tax consequences and attendant risks of investing in the Fund. Although the Fund seeks to minimize and defer the taxes incurred by Common Shareholders in connection with their investment in the Fund, there can be no assurance that it will be successful in this regard. The tax treatment and characterization of the Fund's distributions may change over time due to changes in the Fund's mix of investment returns and changes in the federal tax laws, regulations and administrative and judicial interpretations. Distributions paid on the Common Shares may be characterized variously as net investment income (taxable at ordinary income rates), qualified dividends and capital gains dividends (each taxable at long-term capital gains rates) or return of capital (not currently taxable). The ultimate tax characterization of the Fund's distributions made in a calendar year may not finally be determined until after the end of that calendar year. Distributions to a Common Shareholder that are return of capital will be tax free to the amount of the Common Shareholder's current tax basis in his or her Common Shares, with any distribution amounts exceeding such basis treated as capital gain on a deemed sale of Common Shares. Common Shareholders are required to reduce their tax basis in Common Shares by the amount of tax-free return of capital distributions received, thereby increasing the amount of capital gain (or decreasing the amount of capital loss) to be recognized upon a later disposition of the Common Shares. In order for Fund distributions of qualified dividend income to be taxable at favorable long-term capital gains rates, a Common Shareholder must meet certain prescribed holding period and other requirements with respect to his or her Common Shares.

DISTRIBUTION RISK

The quarterly distributions Common Shareholders will receive from the Fund will be sourced from the Fund's net option premiums, net realized and unrealized gains on stock investments, and dividends and interest income, after payment of Fund expenses. The Fund's cash available for distribution may vary widely over the short- and long-term. If stock prices or stock market volatility declines, the level of premiums from writing index call options and the amounts available for distribution from options activity will likely decrease as well. Payments to close written call options will reduce amounts available for distribution from call option premiums received. Net realized and unrealized gains on the Fund's stock investments will be determined primarily by the direction and movement of the U.S. stock market (and the S&P 500 in particular). Dividends on common stocks are not fixed but are declared at the discretion of the issuer's board of directors. There can be no assurance that quarterly distributions paid by the Fund to the Common Shareholders will be maintained at initial levels or increase over time.

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.

7

INTEREST RATE RISK

The premiums from writing index call options and amounts available for distribution from the Fund's options activity may decrease in declining interest rate environments. The value of the Fund's common stock investments may also be influenced by changes in interest rates. Higher yielding stocks and stocks of issuers whose businesses are substantially affected by changes in interest rates may be particularly sensitive to interest rate risk.

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 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

8

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, Parametric 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 investment 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 [______] 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 [__]0% 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 Tax-Managed BuyWrite 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 $[__] per Common Share.

INVESTMENT OBJECTIVES, POLICIES AND RISKS

INVESTMENT OBJECTIVES

The Fund's primary investment objective is to provide current income and gains, with a secondary objective of capital appreciation. In pursuing its investment objectives, the Fund will evaluate returns on an after-tax basis, seeking to reduce and defer shareholder taxes. There can be no assurance that the Fund will achieve its investment objectives.

Under normal market conditions, the Fund's investment program will consist primarily of (1) owning a diversified portfolio of common stocks that seeks to approximate the pretax investment performance of the S&P Composite Stock Price Index (the "S&P 500") and (2) selling S&P 500 index call options on a continuous basis on substantially the full value of its holdings of common stocks. The Fund will seek to approximate the pretax investment performance of the CBOE S&P 500 BuyWrite Index (the "BXM") and to achieve higher after-tax returns than a pure replication of the BXM strategy by employing a number of tax-management techniques and strategies. The BXM is a passive stock-plus-covered-call index created and maintained by the Chicago Board Options Exchange (the "CBOE").

PRIMARY INVESTMENT POLICIES

GENERAL COMPOSITION OF THE FUND

Under normal market conditions, the Fund will invest its managed assets in a diversified portfolio of common stocks that seeks to approximate the pretax total return performance of the S&P 500. Due to tax considerations, the Fund intends to limit the overlap between its stock portfolio holdings (and any subset thereof) and the S&P 500 to less than 70% at all times. The Fund will utilize portfolio optimization systems and software to seek to minimize the "tracking error" of its stock portfolio's projected performance versus that of the S&P 500. The Fund will invest primarily in common stocks of U.S. issuers. 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"). The Fund normally expects that its investments will be invested across a broad range of industries and market. 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.

Under normal market conditions, the Fund will seek to generate current earnings by employing an options strategy of writing (selling) index call options on the S&P 500. The Fund expects to sell index call options on a continuous basis on substantially the full value of its holdings of common stocks. Writing index call options involves a tradeoff between the option premiums received and reduced participation in potential future stock price appreciation of the Fund's

11

portfolio of common stocks. Generally, the Fund intends to sell S&P 500 call options that are slightly "out-of-the-money," meaning that option exercise prices generally will be slightly higher than the current level of the index at the time the options are written. The Fund seeks to generate current earnings from index option writing premiums and, to a lesser extent, from dividends on stocks held.

The Fund's policies of investing, under normal market circumstances, its managed assets in common stocks and writing index call options with respect to substantially the full value of its holdings of common stocks are not considered to be fundamental by the Fund and can be changed without a vote of the Fund's shareholders. However, these policies 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.

The Fund intends to sell S&P 500 call options that are exchange-listed and "European style," meaning that the options may be exercised only on the expiration date of the option. Index options differ from options on individual securities in that index options (i) are settled in cash rather than by delivery of securities and (ii) reflect price fluctuations in a group of securities or segments of the securities market rather than price fluctuations in a single security.

As the seller of S&P 500 index call options, the Fund will receive cash (the premium) from options purchasers. The purchaser of an S&P 500 index option has the right to any appreciation in the value of the S&P 500 over a fixed price (the exercise price) as of a specified date in the future (the expiration date). Generally, the Fund intends to sell S&P 500 call options that are slightly "out-of-the-money" (i.e., the exercise price generally will be slightly above the current level of the S&P 500 when the option is sold). The Fund will, in effect, sell the potential appreciation in the value of the S&P 500 above the exercise price in exchange for the option premium received. If, at expiration, an S&P 500 index call option sold by the Fund is exercised, the Fund will pay the purchaser the difference between the cash value of the S&P 500 and the exercise price of the option. The premium, the exercise price and the market value of the S&P 500 will determine the gain or loss realized by the Fund as the seller of the index call option.

In implementing the Fund's investment strategy, the Adviser and Sub-Adviser intend to employ a variety of techniques and strategies designed to minimize and defer the federal income taxes incurred by shareholders in connection with their investment in the Fund as described below.

The S&P 500 is an unmanaged index of 500 stocks maintained and published by Standard & Poor's that is market-capitalization weighted and generally representative of the performance of larger stocks traded in the U.S. It is not possible to invest directly in the S&P 500. The BXM is a passive total return index based on holding the stocks in the S&P 500 and selling a series of one-month S&P 500 index call options on the full value of the portfolio. The options are sold at the nearest available exercise price above the prevailing S&P 500 level (i.e., slightly out of the money). The short option position is maintained until expiration, at which time a new one-month call option is written. It is not possible to invest directly in the BXM. The Fund is not sponsored, endorsed, sold or promoted by the CBOE, and the CBOE makes no representation regarding the advisability of investing in the Fund.

INVESTMENT STRATEGY

Eaton Vance will be responsible for managing the Fund's overall investment program, implementing the Fund's index options strategy, providing research support to the Sub-Adviser and supervising the performance of the Sub-Adviser. The Sub-Adviser will be responsible for structuring and managing the Fund's common stock portfolio, including tax-loss harvesting and other tax-management techniques. The Sub-Adviser has developed specialized programs and systems that allow for efficient implementation of the Fund's strategies. The Fund's investments are actively managed, and securities may be bought or sold on a daily basis.

The Adviser believes that a strategy of owning a portfolio of common stocks and selling covered call options (a "buy-write strategy") can provide high current income and gains and attractive risk-adjusted returns. Compared to selling call options on individual stocks, selling index call options can achieve better tax and transactional efficiency because index options are cash-settled "section 1256 contracts" subject to favorable tax treatment and because the markets for index options are generally deeper and more liquid than options on individual stocks.

Eaton Vance further believes that a strategy of owning a portfolio of common stocks whose performance approximates that of the S&P 500 in conjunction with writing index call options on the S&P 500 should generally provide returns that are superior to owning the same stocks without an associated call option writing program 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 buy-write strategy generally be expected to underperform the stock only portfolio. 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 do not materially exceed the long-term historical average of stock market returns.

The Fund will seek to achieve performance from its common stock portfolio that approximates the performance of the S&P 500. To avoid being subject to the "straddle rules" under federal income tax law, the Fund intends to maintain an overlap of less than 70% between its stock portfolio (or any subset thereof) and the S&P 500 on an ongoing basis. The Fund will utilize portfolio optimization systems and software to seek to minimize the "tracking error" of its stock portfolio's projected performance versus that of the S&P 500. The Sub-Adviser will consider a variety of factors in constructing and maintaining the Fund's stock portfolio, including, but not limited to, the overlap between stock portfolio holdings and the S&P 500, the tracking error of the portfolio versus the S&P 500 and stock performance ratings as determined by the Adviser. The Adviser's evaluation of the future performance potential of individual stocks will be one among several considerations in portfolio construction and will not, on a standalone basis, be determinative of portfolio construction. The Adviser's stock ratings will be based primarily on fundamental research.

The Fund's index option strategy is designed to produce current cash flow from options premiums and to moderate the volatility of the Fund's returns. This index option strategy is of a hedging nature, and is not designed to speculate on equity market performance. The Adviser intends to follow an options strategy similar to that of the BXM, selling S&P 500 index call options with a remaining maturity of approximately one month and maintaining its short call options positions until their expiration date, at which time replacement call option positions with a remaining maturity of approximately one month are written. The Adviser intends to sell S&P 500 index call options on substantially the full value of the Fund's common stock holdings. The Adviser does not intend to sell index call options representing amounts greater than the value of the Fund's common stock portfolio (i.e., take a 'naked' position).

In addition to the intended strategy of selling index 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. Derivative instruments may be used 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 index 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.

TAX-MANAGED INVESTING

Taxes are a major influence on the net after-tax returns that investors receive on their taxable investments. There are five potential sources of returns for a Common Shareholder: (1) appreciation or depreciation in the value of the Common Shares; (2) distributions of qualified dividend income; (3) distributions of other investment income and net short-term capital gains; (4) distributions of long-term capital gains (and long-term capital gains retained by the Fund); and
(5) distributions of return of capital. These different sources of investment returns are subject to widely varying federal income tax treatment. Distributions of other investment income (i.e., non-qualified dividend income) and net realized short-term gains are taxed currently as ordinary income, at rates as high as 35%. Distributions of qualified dividend income and net realized long-term gains (whether distributed or retained by the Fund) are taxed currently at rates up to 15% for individuals and other noncorporate taxpayers. Generally, return from appreciation and depreciation in the value of Common Shares and distributions characterized as return of capital are not taxable until the Common Shareholder sells his or her Common Shares. Upon sale, a capital gain or loss (long-term, taxed at rates up to 15% for individuals and other noncorporate taxpayers if the Common Shareholder has held his or her shares more than one year, otherwise short-term taxed at rates up to 35%) equal to the difference between the net proceeds of such sale and the Common Shareholder's adjusted tax basis is realized. The after-tax returns achieved by a Common Shareholder will be substantially influenced by the mix of Fund returns among the different types of returns subject to varying federal income tax treatment.

In implementing the Fund's investment strategy, the Adviser and Sub-Adviser intend to employ a variety of techniques and strategies designed to skew the mix of Fund returns to the types of returns that are most advantageously taxed, thereby seeking to minimize and defer the federal income taxes incurred by Common Shareholders in connection with their investment in the Fund. Such techniques and strategies are expected to include: (1) employing a call options strategy consisting of selling S&P 500 index call options that qualify for treatment as "section 1256 contracts" on which capital gains and losses are generally treated as 60% long-term and 40% short-term, regardless of holding

13

period; (2) limiting the overlap of the Fund's stock portfolio versus the S&P 500 to less than 70% so that the Fund's stock holdings and S&P 500 index call options are not subject to the "straddle rules;" (3) engaging in a systematic program of tax-loss harvesting in the Fund's stock portfolio, periodically selling stock positions that have depreciated in value to realize capital losses that can be used to offset capital gains realized by the Fund; and (4) minimizing the sale of appreciated stock positions to reduce realized capital gains. When an appreciated security is sold, the Fund intends to select for sale the share lots resulting in the most favorable tax treatment, generally those with holding periods sufficient to qualify for long-term capital gains treatment that have the highest cost basis.

In addition, the Fund will seek to earn and distribute "qualified dividend income." Under federal income tax law enacted in 2003, the qualified dividend income of individuals and other noncorporate taxpayers is taxed at long-term capital gain tax rates if certain holding period and other requirements are met. Qualified dividends are dividends from domestic corporations and dividends from foreign corporations that meet certain specified criteria. The Fund generally can pass the tax treatment of qualified dividend income it receives through to Common Shareholders. For the Fund to receive tax-advantaged treatment of its qualified dividend income, the Fund must hold stock paying qualified dividends for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date (or more than 90 days during the associated 181-day period, in the case of certain preferred stocks). In addition, the Fund cannot be obligated to make related payments (pursuant to a short sale or otherwise) with respect to positions in any security that is substantially similar or related property with respect to such stock. Similar provisions apply to each Common Shareholder's investment in the Fund. In order for qualified dividend income paid by the Fund to a Common Shareholder to be taxable at long-term capital gains rates, the Common Shareholder must hold his or her Fund shares for more than 60 days during the 121-day period surrounding the ex-dividend date. The provisions of the Code applicable to qualified dividend income are effective through 2008. Thereafter, qualified dividend income will be taxable as ordinary income unless further legislative action is taken

The Fund may seek to enhance the level of tax-advantaged dividend income it receives by emphasizing higher-yielding stocks in its stock portfolio and by engaging in dividend capture trading. In a dividend capture trade, the Fund sells a stock on or shortly after the stock's ex-dividend date and used the sale proceeds to purchase one or more other stocks that are expected to pay dividends before the next dividend payment on the stock being sold. Through this practice, the Fund may receive more dividend payments over a given time period than if it held a single stock. In order for dividends received by the Fund to qualify for favorable tax treatment, the Fund must comply with the holding period and other requirements set forth in the preceding paragraph. The use of dividend capture trading strategies will expose the Fund to increased trading costs and potentially higher short-term gain or loss.

To seek to protect against price declines in securities holdings with large accumulated gains, the Fund may use various hedging techniques (such as the purchase and sale of futures contracts on stocks and stock indices and options thereon, equity swaps, covered short sales, forward sales of stocks and the purchase and sale of forward currency exchange contracts and currency futures). By using these techniques rather than selling appreciated securities, the Fund can, within certain limitations, reduce its exposure to price declines in the securities without realizing substantial capital gains under current tax law. Derivative instruments may also be used by the Fund to enhance returns or as a substitute for the purchase or sale of securities. As a general matter, dividends received on hedged stock positions are characterized as ordinary income and are not eligible for favorable tax treatment. Dividends received on securities with respect to which the Fund is obligated to make related payments (pursuant to short sales or otherwise) will be treated as fully taxable ordinary income (i.e., income other than tax-advantaged dividends). In addition, use of derivatives may give rise to short-term capital gains and other income that would not qualify for favorable tax treatment. As indicated above, the Fund may invest up to 20% of its total managed assets in 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 objective 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.

COMMON STOCKS

Under normal market conditions, the Fund will invest substantially all 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.

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

14

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.

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.

INDEX OPTIONS GENERALLY

The Fund will pursue its objectives in part by selling S&P 500 index call options on a continuous basis on substantially the full value of its common stock portfolio.

The Fund will sell S&P 500 index options that are exchange-listed and that are "European style," meaning that the options may only be exercised on the expiration date of the option. Index options differ from options on individual securities in that index options (i) are settled in cash rather than by delivery of securities and (ii) reflect price fluctuations in a group of securities or segments of the securities market rather than price fluctuations in a single security.

Option contracts are originated and standardized by the Options Clearing Corporation (the "OCC"). Currently, index options are available on 89 indexes, with new listings added periodically. The Fund will sell S&P 500 index call options that are generally issued, guaranteed and cleared by the OCC. S&P 500 index options currently trade exclusively on the Chicago Board Options Exchange. The Adviser believes that there exists a large trading volume of options, sufficient to fulfill the Fund's requirements to implement its index options strategy.

SELLING INDEX CALL OPTIONS

The Fund's index option strategy is designed to produce current cash flow from options premiums and to moderate the volatility of the Fund's returns. This index option strategy is of a hedging nature, and is not designed to speculate on equity market performance.

As the seller of S&P 500 index call options, the Fund will receive cash (the premium) from the purchaser. The purchaser of the option has the right to any appreciation in the value of the S&P 500 over a fixed price (the exercise price) as of a specified date in the future (the expiration date). Generally, the Fund intends to sell S&P 500 call options that are slightly "out-of-the-money" (i.e., the exercise price generally will be slightly above the current level of the S&P 500 when the option is sold). The Fund will, in effect, sell the potential appreciation in the value of the S&P 500 above the exercise price in exchange for the option premium received. If, at expiration, an S&P 500 index call option sold by the Fund is exercised, the Fund will pay the purchaser the difference between the cash value of the S&P 500 and the exercise price of the option. The premium, the exercise price and the market value of the S&P 500 will determine the gain or loss realized by the Fund as the seller of the index call option.

15

Prior to the expiration, the Fund may close an option position by making an offsetting market purchase of identical option contracts (same type, underlying index, exercise price and expiration). The cost of closing transactions and payments in settlement of exercised options will reduce the net option premiums available for distribution by the Fund. The reduction in net option premiums should generally be offset, at least in part, by appreciation in the value of the Fund's common stock portfolio and by the opportunity to realize higher premium income from selling new index options at higher exercise prices.

The Fund will sell only "covered" call options. An index call option is considered covered if the Fund maintains with its custodian assets determined to be liquid (in accordance with procedures established by the Board of Trustees) in an amount equal to the contract value of the index. An index call option also is covered if the Fund holds a call on the same security or index 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 (in accordance with procedures established by the Board of Trustees).

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 written by the Fund is exercised, the Fund realizes on the expiration date a capital gain if the cash payment made by the Fund upon exercise is less than the premium received from writing the option and a capital loss if the cash payment made is more than the premium received. If a written option is repurchased, the Fund realizes upon the closing purchase transaction a capital gain if the cost of the closing option is less than the premium received from writing the option and a capital loss if the cost of the closing option is more than the premium received. Because exchange-listed S&P 500 index options are "section 1256 contracts," the Fund's gains and losses thereon generally will be treated as 60% long-term and 40% short-term capital gain or loss, regardless of holding period. In addition, the Fund generally will be required to "mark to market" (I.E., treat as sold for fair market value) each outstanding index option position at the close of each taxable year. See "Federal Income Tax Matters."

The principal factors affecting the market value of an option contract include supply and demand in the options market, interest rates, the current market price of the underlying index in relation to the exercise price of the option, the actual or perceived volatility associated with the underlying index, and the time remaining until the expiration date. The premium received for an option written by the Fund is recorded as an asset of the Fund and its obligation under the option contract as an equivalent liability. The Fund then adjusts over time the liability as the market value of the option changes. The value of each written option will be marked to market daily and 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 and exercise 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 associated with the Fund's options strategy will vary depending on market circumstances and other factors.

The standard contract size for exchange-listed S&P 500 index option is [__]. There are three items needed to identify a particular S&P 500 index option contract: (1) the expiration month, (2) the exercise (or strike) price and (3) the type (i.e., call or put). For example, [__] S&P 500 index call options provide the option holder the right to [__]. A call option whose exercise price is above the current price of the underlying index is called "out-of-the-money" and a call option whose exercise price is below the current price of the underlying index is called "in-the-money."

The following is a conceptual example of the returns that may be achieved from a buy-write investment strategy that consist of holding a portfolio of stocks whose performance matches the S&P 500 and selling S&P 500 index call options on the full value of the stock position. This example is not meant to represent the performance of actual option contracts or the Fund.

[Example details to be added by pre-effective amendment.]

The return over the period until option expiration earned by the holder of a portfolio of stocks whose performance matches the S&P 500 and who writes S&P 500 index call options on the full value of the stock position and maintains the options position until expiration will be as follows: (1) if the S&P 500 declines __%, the option will expire worthless and the holder will have a net return of zero (option premium offsets loss in stock portfolio); (2) if the S&P 500 is flat, the option will again expire worthless and the holder will have a net return of _% (option premium plus no gain or loss on stock); (3) if the S&P 500 rises __%, the option will again expire with no value and the holder will

16

have a net return of __% (option premium plus __% stock return); and (4) if the index rises __%, the exercise of the option would limit stock portfolio gain to __% and total net return to __%. If the index value at exercise exceeds the exercise price, returns from the position are capped at __%.

As demonstrated in the example, writing S&P 500 index call options can lower the variability of potential return outcomes and can enhance returns in three of four market performance scenarios (down, flat or moderately up). Only when the level of the S&P 500 at option expiration exceeds the sum of the premium received and the option exercise price would the buy-write strategy be expected to provide lower returns than the stock-only alternative. The amount of downside protection afforded by the buy-write strategy in declining market scenarios is limited, however, to the amount of option premium received. If the S&P 500 declines by an amount greater than the option premium, the buy-write strategy would generate an investment loss. Returns from implementing a buy-write strategy using S&P 500 index options will also be substantially affected by the performance of the portfolio of stocks held versus the S&P 500.

ADDITIONAL INVESTMENT PRACTICES

In addition to its primary investment strategies as described above, the Fund may engage in the following investment practices:

TEMPORARY INVESTMENTS

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. 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. In moving to a substantial temporary investments position and in transitioning from such a position back into 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 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 later 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 transacted securities 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. The Fund does not intend to enter into forward commitment or when-issued transactions 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 that 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 by the Fund 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

17

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 index call options, the Fund may invest up to 20% of its total assets in other 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 U.S. 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.

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 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 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.

18

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.

Short sales against-the-box can be a tax-efficient alternative to the sale of an appreciated securities position. The ability to use short sales against-the-box 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.

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 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 it does not currently intend 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 is 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 cash available for distribution.

PORTFOLIO TURNOVER

The Fund will buy and sell securities to seek to accomplish it investment objectives. Portfolio turnover generally involves expense to the Fund, including brokerage commissions and other transaction costs on the sale of securities and reinvestment in other securities. The Fund expects to maintain high turnover in index call options, based on the Adviser's intent to sell index call options on substantially the full value of its holdings of common stocks and to roll forward its options positions on a monthly basis. For its stock holdings, the Fund's annual portfolio turnover rate is expected to exceed that of the S&P 500 due to turnover in connection with the Fund's tax loss harvesting and dividend capture strategies. The Fund intends to maintain low turnover in stock holdings that have appreciated substantially from cost. On an overall basis, the Fund's

19

annual turnover rate may exceed 100%. A high turnover rate (100% or more) necessarily involves greater trading costs to the Fund.

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. Because the Fund intends to sell index call options on a continuous basis on substantially the full value of its common stock holdings, the Fund's appreciation potential from equity market performance will be limited. 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

Under normal market conditions, the Fund will invest its managed assets in a diversified portfolio of common stocks. 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 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 stocks 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.

RISK OF SELLING INDEX CALL OPTIONS

The Fund expects to sell S&P 500 index call options on a continuous basis on substantially the full value of its holdings of common stocks. The purchaser of an index call option has the right to any appreciation in the value of the index over the exercise price of the call option on the expiration date. Because their exercise is settled in cash, sellers of index call options such as the Fund cannot provide in advance for their potential settlement obligations by acquiring and holding the underlying securities. The Fund intends to mitigate the risks of its written index call positions by holding a diversified portfolio of stocks similar to those on which the S&P 500 is based. However, the Fund does not intend to acquire and hold a portfolio containing exactly the same stocks as the S&P 500 and, as a result, bears the risk that the performance of the securities held by the Fund will vary from the performance of the S&P 500. Index options written by the Fund will be priced on a daily basis. Their value will be affected primarily by changes in the price and dividend rates of the underlying common stocks in the S&P 500, changes in actual or perceived volatility of the S&P 500 and the remaining time to the options' expiration. The trading price of S&P 500 index options will also be affected by liquidity considerations and the balance of purchase and sale orders.

20

A decision as to whether, when and how to use options involves the exercise of skill and judgment, and even a well-conceived and well-executed options program may be adversely affected by market behavior or unexpected events. As the writer of S&P 500 index call options, the Fund will forgo, during the option's life, the opportunity to profit from increases in the value of the S&P 500 above the sum of the option premium received and the exercise price of the call option, but retains the risk of loss, minus the option premium received, should the value of the S&P 500 decline. When a call option is exercised, the Fund will be required to deliver an amount of cash determined by the excess of the value of S&P 500 at contract termination over the exercise price of the option. Thus, the sale of index call options may require the Fund to sell portfolio securities to generate cash at inopportune times or for unattractive prices.

The trading price 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 a call option position by buying 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 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 hours of trading for options may not conform to the hours during which common stocks held by the Fund are traded. To the extent that the options markets close before the markets for securities, significant price and rate movements can take place in the securities markets that would not be reflected concurrently in the options markets. Index call options are marked to market daily and their value is substantially affected by changes in the value of and dividend rates of the underlying index, changes in interest rates, changes in the actual or perceived volatility of the associated index and the remaining time to the options' expiration, as well as trading conditions in the options market.

TAX RISK

Reference is made to "Federal Income Tax Matters" for an explanation of the federal income tax consequences and attendant risks of investing in the Fund. Although the Fund seeks to minimize and defer the taxes incurred by Common Shareholders in connection with their investment in the Fund, there can be no assurance that it will be successful in this regard. The tax treatment and characterization of the Fund's distributions may change over time due to changes in the Fund's mix of investment returns and changes in the federal tax laws, regulations and administrative and judicial interpretations. Distributions paid on the Common Shares may be characterized variously as net investment income (taxable at ordinary income rates), qualified dividends and capital gains dividends (each taxable at long-term capital gains rates) or return of capital (not currently taxable). The ultimate tax characterization of the Fund's distributions made in a calendar year may not finally be determined until after the end of that calendar year. Distributions to a Common Shareholder that are return of capital will be tax free to the amount of the Common Shareholder's current tax basis in his or her Common Shares, with any distribution amounts exceeding such basis treated as capital gain on a deemed sale of Common Shares. Common Shareholders are required to reduce their tax basis in Common Shares by the amount of tax-free return of capital distributions received, thereby increasing the amount of capital gain (or decreasing the amount of capital loss) to be recognized upon a later disposition of the Common Shares. In order for Fund distributions of qualified dividend income to be taxable at favorable long-term capital gains rates, a Common Shareholder must meet certain prescribed holding period and other requirements with respect to his or her Common Shares.

DISTRIBUTION RISK

The quarterly distributions Common Shareholders will receive from the Fund will be sourced from the Fund's net option premiums, net realized and unrealized gains on stock investments, and dividends and interest income, after payment of Fund expenses. The Fund's cash available for distribution may vary widely over the short- and long-term. If stock prices or stock market volatility declines, the level of premiums from writing index call options and the amounts available for distribution from options activity will likely decrease as well. Payments to close written call options will reduce amounts available for distribution from call option premiums received. Net realized and unrealized gains on the Fund's stock investments will be determined primarily by the direction and movement of the U.S. stock market (and the S&P 500 in particular). Dividends on common stocks are not fixed but are declared at the discretion of the issuer's board of directors. There can be no assurance that quarterly distributions paid by the Fund to the Common Shareholders will be maintained at initial levels or increase over time.

21

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 premiums from writing index call options and amounts available for distribution from the Fund's options activity may decrease in declining interest rate environments. The value of the Fund's common stock investments may also be influenced by changes in interest rates. Higher yielding stocks and stocks of issuers whose businesses are substantially affected by changes in interest rates may be particularly sensitive to interest rate risk.

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 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.

22

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, Parametric 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 investment 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.

23

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 $[__] billion as of October 31, 2004, including approximately $[___] 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, Eaton Vance will be responsible for managing the Fund's overall investment program, implementing the Fund's index options strategy, providing the Sub-Adviser with research support and supervising the performance of the Sub-Adviser. As described below under the caption "The Sub-Adviser," the Sub-Adviser will be responsible for structuring and managing the Fund's common stock portfolio, including tax-loss harvesting and other tax-management techniques. 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 [__]% 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, 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.

[__] and other Eaton Vance investment professionals comprise the Eaton Vance investment team responsible for the overall management of the Fund's investment program, setting and implementing the Fund's options strategy, providing research support to the Sub-Adviser and supervising the Sub-Adviser.

THE SUB-ADVISER

Eaton Vance has engaged its affiliate Parametric as a sub-adviser to the Fund. The Sub-Adviser will be responsible for structuring and managing the Fund's common stock portfolio, including tax-loss harvesting and other tax-management techniques. The Sub-Adviser has developed specialized programs and systems that allow for efficient implementation of the Fund's strategies. The Sub-Adviser's principal office is located at 1151 Fairview Avenue North, Seattle, WA 981209. Parametric was founded in 1987. In September of 2003, Eaton Vance Corp, the parent company of Eaton Vance, acquired an 80% interest in the firm with the remaining 20% owned primarily by Parametric employees. Parametric specializes in managing broadly diversified, risk controlled and tax-efficient portfolios for institutional, high net worth investors and investment company clients and their advisers. Parametric managed approximately $[__] billion in assets as of October 31, 2004.

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 [__]% 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.

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.

24

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 quarterly distributions to Common Shareholders sourced from the Fund's cash available for distribution. "Cash available for distribution" will consist of the Fund's net option premiums, net realized and unrealized gains on stock investments, and dividends and interest income, after payment of 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 [60-90] days and paid approximately [90-120] days after the completion of this offering, depending on market conditions.

The Fund's annual distributions 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. To the extent that that Fund's net investment income for any year exceeds the total quarterly 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. Over time, all of the Fund's investment company taxable income will be distributed.

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) or, alternatively, to retain all or a portion of the year's net capital gain and pay federal income tax on the retained gain. As provided under federal tax law, Common Shareholders of record as of the end of the Fund's taxable year will include their attributable share of the retained gain in their income for the year as a long-term capital gain, and will be entitled to a tax credit or refund for the tax paid on their behalf by the Fund. The Fund may treat the cash value of tax credit and refund amounts in connection with retained capital gains as a substitute for equivalent cash distributions.

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 dividends, 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. Distributions in any year may include a substantial return of capital component. 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 for distribution. As a result, the distributions paid by the Fund for any particular quarter may be more or less than the amount of cash available for distribution from that quarterly period. In certain circumstances, the Fund may be required to sell a portion of its investment portfolio to fund distributions. Distributions 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 (generally once per taxable year). In the event that such an exemptive order is obtained, the Fund will consider increasing the frequency of its regular distributions to Common Shareholders

25

from quarterly to monthly. The Fund will not designate more than the permitted number of net capital gain dividends until it receives such an exemptive order. There is no guarantee that the SEC will grant exemptive relief. Failure to receive exemptive relief would increase the likelihood that in certain taxable years the Fund would retain all or a portion of the year's net capital gain and pay tax on the retained gain as described above. The Adviser does not believe that retaining capital gains and paying tax thereon would have a material adverse affect on the Fund or the Common Shareholders.

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 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 thereon. 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.

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) or, alternatively, to retain all or a portion of the year's net capital gain and pay federal income tax on the retained gain. As provided under federal tax law, Common Shareholders of record as of the end of the Fund's taxable year will include their attributable share of the retained gain in their income for the year as long-term capital gain (regardless of holding period in the Common Shares), and will be entitled to a tax credit or refund for the tax paid on their behalf by the Fund. Common Shareholders of record for the retained capital gain will also be entitled to increase their tax basis in their Common Shares by 65 percent of the allocated gain. 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 their holding period in the Common Shares.

If, for any calendar year, the Fund's total distributions exceed the Fund's net investment taxable income and capital gain distributions, 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.

In the case of Fund transactions involving S&P 500 index call options (or other listed options on broad-based securities indices), 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. 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. In addition to most index call options, Section 1256 Contracts include certain other options contracts, certain regulated futures contracts, and certain other financial contracts.

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

26

of holding one or more other positions. The Fund expects that the index call options it writes will not be considered straddles for this purpose because the Fund's portfolio of common stocks will be sufficiently dissimilar from the components of the S&P 500 under applicable guidance established by the IRS. Under certain circumstances, however, the Fund may enter into options transaction or certain other 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 generally 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 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 all 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 net capital gain or loss is treated as 60% long-term and 40% short-term capital gain or loss if attributable to the
Section 1256 Contract positions, or all short-term capital gain or loss if attributable to the non-Section 1256 Contract positions.

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 if the transaction is closed out not later than thirty days after the end of the 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.

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 Common 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 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. In order for qualified dividends paid by the Fund to a Common Shareholder to be taxable at long-term capital gains rates, the Common Shareholder must hold his or her Fund shares for more than 60 days during the 121-day period surrounding the ex-dividend date. For the Fund to receive tax-advantaged dividend income, the Fund must hold stock paying qualified dividend income for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date (or more than 90 days during the associated 181-day period, in the case of certain preferred stocks). In addition, the Fund cannot be obligated to make related payments (pursuant to a short sale or otherwise) with respect to positions in any security that is substantially similar or related property with respect to such stock. 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

27

Fund generally apply to taxable years 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 sale proceeds. 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.

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 capital gain dividends) automatically reinvested in Common Shares. Common Shareholders may elect to participate in the Plan by completing the dividend reinvestment 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.

28

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 could 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.

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 Plan 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 purchased at a discount to market price and having a current value that exceeds the cash distributions they would have otherwise received on their Common Shares. If the market price (plus commissions) of the Fund's Common Shares is below their net asset value, Plan participants will receive Common Shares with a net asset value that exceeds the cash distributions they would have otherwise received on their Common Shares. There may, however, be insufficient Common Shares available in the market at prices below net asset value to satisfy the Plan's requirements, in which case the Plan Agent will acquire newly issued Common Shares. Also, since the Fund does not redeem its Common Shares, the price on resale of Common Shares may be more or less than their 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 [________ __, 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 business trust established under Massachusetts law may, in certain limited circumstances, 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. 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 to reduce trading discounts in the Common Shares. The Board,

30

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 conditions and such other events or conditions that 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 approximating their net asset value. The Board, in consultation with Eaton Vance, may from time to time review other possible actions to reduce trading discounts in the Common Shares.

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 distribution 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 under the 1940 Act. In this regard, holders of preferred shares may, for example, be entitled to elect a majority of the Fund's Board if only one dividend on the preferred shares is in arrears.

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 no assurance can be given as to the nature or extent of the guidelines that 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 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 a Rating Agency would be more or less restrictive than as described in this Prospectus.

31

CREDIT FACILITY/COMMERCIAL PAPER PROGRAM

The Fund has no current intention to borrow money for the purpose of obtaining investment leverage. If, in the future, the Fund determines to engage in investment leverage using borrowings, the Fund may enter into definitive agreements with respect to a credit facility/commercial paper program or other borrowing 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. Borrowings under 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 no sinking fund or mandatory retirement provisions would be expected to apply. 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 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 that amounts available for distribution derived from securities purchased with the proceeds of leverage exceed the cost of such 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 leverage 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.

32

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 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.

UNDERWRITING

The underwriters named below (the "Underwriters"), acting through [__], [__], New York, New York, [__], [__], and [__], [__], as lead managers and [__], [__] and [__], as their representatives (together with the lead managers, the "Representatives"), have severally agreed, subject to the terms and conditions of the Underwriting Agreement with the Fund and Eaton Vance (the "Underwriting Agreement"), to purchase from the Fund the number of Common Shares set forth opposite their respective names. The Underwriters are committed to purchase and pay for all of such Common Shares (other than those covered by the over-allotment option described below) if any are purchased.

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



                                                                     _________

  Total............................................................. =========

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 $[__] per Common Share ([__]% 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 , 2005.

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 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 ($[__]).

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 [__]% 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

34

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 [__] (the "Shareholder Servicing Agent") and Eaton Vance, the Shareholder Servicing Agent will (i) at the request of and as specified by Eaton Vance, undertake to make available public information pertaining to the Fund on an ongoing basis and to communicate to investors and prospective investors the Fund's features and benefits (including arranging periodic seminars or conference calls for Eaton Vance to communicate to investors, responding to questions from current or prospective shareholders and contacting specific shareholders, where appropriate), provided that services shall not include customary market research information provided by the Shareholder Servicing Agent or its registered broker-dealer affiliates in the ordinary course of their business; (ii) at the request of and as specified by Eaton Vance, make available to investors and prospective investors market price, net asset value, yield and other information regarding the Fund (provided that services shall not include customary market research information provided by the Shareholder Servicing Agent or its registered broker-dealer affiliates in the ordinary course of their business), if reasonably obtainable, for the purpose of maintaining the visibility of the Fund in the investor community; (iii) at the request of Eaton Vance or the Fund, provide certain economic research and statistical information and reports, if reasonably obtainable, to Eaton Vance or the Fund and consult with representatives of Eaton Vance and/or the Board in connection therewith, which information and reports shall include: (a) statistical and financial market information with respect to the Fund's market performance; and (b) comparative information regarding the Fund and other closed-end management investment companies with respect to (1) the net asset value of their respective shares, (2) the respective market performance of the Fund and such other companies, and (3) other relevant performance indicators. Except as legally required, such information and reports may not be quoted or referred to, orally or in writing, reproduced or disseminated by the Fund or any of its affiliates or any of their agents, without the prior written consent of the Shareholder Servicing Agent, which consent will not be unreasonably withheld; and (iv) at the request of Eaton Vance or the Fund, provide information to and consult with Eaton Vance and/or the Board with respect to applicable strategies designed to address market value discounts, which may include share repurchases, tender offers, modifications to dividend policies or capital structure, repositioning or restructuring of the Fund, conversion of the Fund to an open-end investment company, liquidation or merger; including providing information concerning the use and impact of the above strategic alternatives by other market participants; provided, however, that under the terms of the Shareholder Servicing Agreement, the Shareholder Servicing Agent is not obligated to render any opinions, valuations or recommendations of any kind or to perform any such similar services. For these services, Eaton Vance will pay the Shareholder Servicing Agent a fee computed daily and payable quarterly equal, on an annual basis, to [ ]% of the Fund's average daily gross assets. The sum 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. The Shareholder Servicing Agreement will continue so long as the Advisory Agreement remains in effect between the Fund and the Adviser or any successor in interest or affiliate of the Adviser, as and to the extent that such Advisory Agreement is renewed periodically in accordance with the 1940 Act.

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 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).

2

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.

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

3

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

(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.

The purpose of the Governance Committee is to consider, evaluate and make recommendations to the Board of Trustees with respect to the structure, membership and operation of the Board of Trustees and the Committees thereof, including the nomination and selection of non-interested Trustees and the compensation of non-interested Trustees.]

[The Governance Committee will, when a vacancy exists or is anticipated, consider any nominee for noninterested Trustee recommended by a shareholder if such recommendation is submitted to the Governance Committee, contains sufficient background information concerning the candidate and is received in a sufficiently timely manner.

Messrs. [ ] (Chairman), [ ] and [ ] and [ ] are members of the Audit Committee of the Board of Trustees of the Fund. The Board of Trustees has designated Messrs. [ ], [ ] and [ ], each a non-interested Trustee, as audit committee financial experts. The Audit Committee's purposes are to (i) oversee the Fund's accounting and financial reporting processes, its internal control over financial reporting, and, as appropriate, the internal control over financial reporting of certain service providers; (ii) oversee or, as appropriate, assist Board oversight of the quality and integrity of the Fund's financial statements and the independent audit thereof; (iii) oversee, or, as appropriate, assist Board oversight of, the Fund's compliance with legal and regulatory requirements that relate to the Fund's accounting and financial reporting, internal control over financial reporting and independent audits; (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 the 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 the Fund.

6

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 [ ] times, the Audit Committee and Special Committee have met [ ] times.

[When considering approval of the Advisory Agreement between the Fund and the Adviser, and the Sub-Advisory Agreement between the Adviser and Parametric, 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 Parametric;

> 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 Parametric's results and financial condition and the overall organization of the Adviser and the Sub-Adviser;

> Arrangements regarding the distribution of Fund shares;

> 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;

> Parametric'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 Parametric;

> 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 Parametric, the Special Committee reviewed material furnished by Eaton Vance and Parametric at the initial Board meeting held on [ ], 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 Parametric 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 Parametric 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

7

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 Parametric'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 evaluating the fees to be paid to Parametric, the Special Committee considered and discussed fees paid to other investment sub-advisers in similar circumstances, as well as fees charged by Parametric 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 Parametric, 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 [ ], whereby the Adviser (and not the Fund) would pay [ ] to provide upon request certain market data and reports to support shareholder services pursuant to the agreement.]

NON-INTERESTED TRUSTEES

[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, Parametric or any person controlling, controlled by or under common control with EVC, EVD or Parametric.

[During the calendar years ended December 31, 200[3] and December 31, 200[4], no non-interested Trustee (or their immediate family members) had:

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

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

[During the calendar years ended December 31, 200[3] and December 31, 200[4], no officer of EVC, EVD, Parametric or any person controlling, controlled by or under common control with EVC, EVD or Parametric 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 [MONTH] [DAY], 200[5], 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, 200[4], 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 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, 2005 is available (1) without charge, upon request, by calling 1-800-262-1122, and (2) on the

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 [ ], 200[ ] 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 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 Parametric 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, William H. Smith, Jr., 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. Hawkes, Faust, Jeffrey P. Beale, Alan R. Dynner, 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.

10

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. Parametric acts as the Fund's investment sub-adviser and provides advice on and execution of the Fund's equity portfolio and options strategy pursuant to a sub-advisory agreement between the Adviser and Parametric (the "Sub-Advisory Agreement"). The Sub-Adviser's principal office is located at 1151 Fairview Avenue North, Seattle, WA 981209. Parametric was founded in 1987. In September of 2003, Eaton Vance Corp, the parent company of Eaton Vance, acquired an 80% interest in the firm with the remaining 20% owned primarily by Parametric employees. Parametric specializes in managing broadly diversified, risk controlled and tax-efficient portfolios for institutional, high net worth investors and investment company clients and their advisers. Parametric managed approximately $[ ] billion in assets as of [October 31], 2004..

Under the terms of the Sub-Advisory Agreement, Parametric 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 Parametric under the Sub-Advisory Agreement, Eaton Vance pays Parametric a fee, payable monthly, in an annual amount equal to [ ]% of the average daily gross assets of the Fund.

The Sub-Advisory Agreement continues until [ ], 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 Parametric upon 3 months notice. As discussed above, Eaton Vance may terminate the Sub-Advisory Agreement and directly assume responsibility for the services provided by Parametric 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 Parametric 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, Parametric and the Fund have adopted Codes of Ethics governing personal securities transactions. Under the Codes of Ethics, Eaton Vance and Parametric 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.

Under the general supervision of the Fund's Board of Trustees, Eaton Vance 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. 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.

Eaton Vance will furnish to the Fund all office facilities, equipment and personnel for administering the affairs of the Fund. Eaton Vance will compensate all Trustees and officers of the Fund who are members of the Eaton

11

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, 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.

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, Parametric as the Sub-Adviser. As used below, "Adviser" refers to Eaton Vance and Parametric, 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, 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."

14

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 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

15

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 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 December 31, 2002 and beginning before January 1, 2009. Thereafter, the Fund's dividends, other than capital gain

16

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 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.

17

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 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.

18

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.

NOTE 1: ORGANIZATION

The Eaton Vance Tax-Managed BuyWrite Income Fund (the "Fund") was organized as a Massachusetts business trust on [ ], 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 [ ] 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 $[ ].

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 $[ ] the Fund has estimated the cost of the offering to be approximately $[ ] all of which would be paid by the Fund. Any amount in excess of $[ ] would be paid by Eaton Vance Management.

The Fund's primary investment objective is to provide current income and gains, with a secondary objective of capital appreciation. The Fund will pursue its investment objectives by investing primarily in a portfolio of common stocks, seeking to substantially replicate the price movements of the S&P 500 Composite Stock Price Index ("S&P 500"). Under normal market conditions, the Fund will seek to generate current earnings from option premiums by selling index call options on the S&P 500. In managing its common stock investments and index call option strategy, the Fund will employ various techniques seeking to optimize the federal income tax consequences to common shareholders of investing in the Fund. 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 [ ] common shares.

NOTE 3: INVESTMENT MANAGEMENT AGREEMENT

Pursuant to an investment advisory agreement between the Adviser and the Fund, the Fund has agreed to pay an investment advisory fee, payable on a monthly basis, at an annual rate of [ ]% of the average daily gross assets of the Fund. Gross assets of the Fund shall be calculated by deducting accrued liabilities of the Fund not including the amount of any preferred shares outstanding or the principal amount of any indebtedness for money borrowed.

Pursuant to a sub-advisory agreement among the Fund, the Adviser and Parametric Portfolio Associates LLC, the Adviser has agreed to pay a sub-advisory fee, in an annual amount equal to [ ]% of the average daily gross assets of the Fund.

NOTE 4: FEDERAL INCOME TAXES

The Fund intends to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income, including any net realized gain on investments.

ITEM 29. INDEMNIFICATION


The Registrant's By-Laws filed herewith contain, and the form of Underwriting Agreement to be filed by amendment is expected to 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); and (iii) the Form ADV of Eaton Vance Management (File No. 801-15930) filed with the Commission, all of which are incorporated herein by reference.

ITEM 31. LOCATION OF ACCOUNTS AND RECORDS

All applicable accounts, books and documents required to be maintained by the Registrant by Section 31(a) of the Investment Company Act of 1940 and the Rules promulgated thereunder are in the possession and custody of the Registrant's custodian, Investors Bank & Trust Company, 200 Clarendon Street, 16th Floor, Boston, MA 02116, and its transfer agent, PFPC Inc., 4400 Computer Drive, Westborough, MA 01581-5120, with the exception of certain corporate documents and portfolio trading documents which are in the possession and custody of Eaton Vance Management, The Eaton Vance Building, 255 State Street, Boston, MA 02109.

b. for the purpose of determining any liability under the Securities Act, each post- effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

ARTICLE II

TRUSTEES

SECTION 2.1. MANAGEMENT OF THE TRUST. The business and affairs of the Trust shall be managed by the Trustees and they shall have all powers and authority necessary, appropriate or desirable to perform that function.

SECTION 2.2. NUMBER OF TRUSTEES. The number of Trustees shall be such number as shall be fixed from time to time by a written instrument signed by a majority of the Trustees, provided, however, that the number of Trustees shall in no event be less than two (2) nor more than fifteen (15). No reduction in the number of Trustees shall have the effect of removing any Trustee from office prior to the expiration of his term unless the Trustee is specifically removed pursuant to Section 2.3 or Section 2.7 of this Article II at the time of decrease.

SECTION 2.3. TERM OF OFFICE OF TRUSTEES. The Board of Trustees shall be divided into three classes. Within the limits above specified, the number of the Trustees in each class and the class which each Trustee is assigned shall be determined by resolution of the Board of Trustees. The term of office of the first class shall expire on the date of the first annual meeting of Shareholders or special meeting in lieu thereof following the effective date of the Registration Statement. The term of office of the second class shall expire on the date of the second annual meeting of Shareholders or special meeting in lieu thereof following the effective date of the Registration Statement. The term of office of the third class shall expire on the date of the third annual meeting of Shareholders or special meeting in lieu thereof following the effective date of the Registration Statement. Upon expiration of the term of office of each class as set forth above, the number of Trustees in such class, as determined by the Board of Trustees, shall be elected for a term expiring on the date of the third annual meeting of Shareholders or special meeting in lieu thereof following such expiration to succeed the Trustees whose terms of office expire. The Trustees shall be elected at an annual meeting of the Shareholders or special meeting in lieu thereof called for that purpose, except as provided in
Section 2.3 of this Article and each Trustee elected shall hold office until his successor shall have been elected and shall have qualified; except (a) that any Trustee may resign his trust (without need for prior or subsequent accounting) by an instrument in writing signed by him and delivered to the other Trustees, which shall take effect upon such delivery or upon such later date as is specified therein; (b) that any Trustee may be removed (provided the aggregate number of Trustees after such removal shall not be less than the number required by Section 2.2 hereof) for cause, at any time by written instrument, signed by the remaining Trustees, specifying the date when such removal shall become effective; and (c) that any Trustee who requests in writing to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees, and he shall execute and deliver such documents as the remaining Trustees shall require for the purpose of conveying to the Fund or the remaining Trustees any Fund property held in the name of the resigning or removed Trustee. Upon the incapacity or death of any Trustee, his legal representative shall execute and deliver on his behalf such document as the remaining Trustees shall require as provided in the preceding sentence.

SECTION 2.4. RESIGNATION AND APPOINTMENT OF TRUSTEES. In case of the declination, death, resignation, retirement, removal or inability of any of the Trustees, or in case a vacancy shall, by reason of any increase in number, or for any other reason, exist, the remaining Trustees or, prior to the public offering of Shares of the Fund, if only one Trustee shall then remain in office, the remaining Trustee, shall fill such vacancy by appointing such other person as they, or anyone of them, in their discretion, shall see fit. Such appointment shall be evidenced by a written instrument signed by a majority of the remaining Trustees or by the remaining Trustee, as the case may be. Any such appointment shall not become effective, however, until the person named in the written

3

instrument or appointment shall have accepted in writing such appointment and agreed in writing to be bound by the terms of the Declaration. Within twelve months of such appointment, the Trustees shall cause notice of such appointment to be mailed to each Shareholder at his address as recorded on the books of the Fund. An appointment of a Trustee may be made by the Trustees then in office and notice thereof mailed to Shareholders as aforesaid in anticipation of a vacancy to occur by reason of retirement, resignation or increase in number of Trustees effective at a later date, provided that said appointment shall become effective only at or after the effective date of said retirement, resignation or increase in number of Trustees. The power of appointment is subject to the provisions of
Section 16(a) of the 1940 Act.

SECTION 2.5. VACANCIES. The death, declination, resignation, retirement, removal or incapacity of the Trustees, or any one of them, shall not operate to annul the Fund or to remove any existing agency created pursuant to the terms of this Declaration. Whenever a vacancy in the number of Trustees shall occur, until such vacancy is filled as provided in Section 2.3, the Trustees in office, regardless of their number, shall have all the duties imposed upon the Trustees by the Declaration and only such Trustees shall be counted for the purposes of establishing the existence of a quorum or performing such duties or exercising such powers of the Trustees as described in this Declaration. A written instrument certifying the existence of such vacancy signed by a majority of the Trustees shall be conclusive evidence of the existence of such vacancy.

SECTION 2.6. DELEGATION OF POWER TO OTHER TRUSTEES. Subject to the provisions of the 1940 Act, any Trustee may, by power of attorney, delegate his power for a period not exceeding six (6) months at any one time to any other Trustee or Trustees; provided that in no case shall less than two (2) Trustees personally exercise the powers granted to the Trustees under the Declaration except as herein otherwise expressly provided.

SECTION 2.7. REMOVAL OF TRUSTEES BY THE SHAREHOLDERS. The Fund shall comply with the provisions of Section 16(c) of the 1940 Act as though applicable to the Fund, and with interpretations hereof by the Commission staff, insofar as such provisions and interpretations provide for the removal of trustees of common-law trusts and the calling of Shareholder meetings for such purpose; provided, however, that the Fund may at any time or from time to time apply to the Commission for one or more exemptions from all or part of said Section 16(c) or a staff interpretation thereof and, if exemptive order(s) or interpretation(s) are issued or provided by the Commission or its staff, such order(s) or interpretation(s) shall be deemed part of Section 16(c) for the purpose of applying this Section 2.7.

ARTICLE IV

LIMITATIONS OF LIABILITY OF SHAREHOLDERS, TRUSTEES AND OTHERS

SECTION 4.1. NO PERSONAL LIABILITY OF SHAREHOLDERS, TRUSTEES, OFFICERS AND EMPLOYEES. No Shareholder shall be subject to any personal liability whatsoever to any Person in connection with Trust Property or the acts, obligations or affairs of the Trust or any Class or Series thereof. All Persons dealing or contracting with the Trustees as such or with the Trust or any Class or Series thereof or having any claim against the Trust or any Class or Series thereof shall have recourse only to the Trust or such Class or Series for the payment of their claims or for the payment or satisfaction of claims, obligations or liabilities arising out of such dealings or contracts. No Trustee, officer or employee of the Trust, whether past, present or future, shall be subject to any personal liability whatsoever to any such Person, and all such Persons shall look solely to the Trust Property, or to the assets of one or more specific Class or Series of the Trust if the claim arises from the act, omission or other conduct of such Trustee, officer or employee with respect to only such Class or Series, for satisfaction of claims of any nature arising in connection with the affairs of the Trust or such Class or Series. If any Shareholder, Trustee, officer or employee, as such, of the Trust is made a party to any suit or proceeding to enforce any such liability of the Trust or any Class or Series thereof, he shall not, on account thereof, be held to any personal liability.

SECTION 4.2. TRUSTEE'S GOOD FAITH ACTION; ADVICE TO OTHERS; NO BOND OR SURETY. The exercise by the Trustees of their powers and discretions hereunder shall be binding upon all Interested Parties. A Trustee shall not be liable for errors of judgment or mistakes of fact or law. The Trustees shall not be responsible or liable in any event for any neglect or wrongdoing of them or of any officer, agent, employee, consultant, investment adviser or other adviser, administrator, distributor or principal underwriter, custodian or transfer, dividend disbursing, shareholder servicing or accounting agent of the Trust, nor shall any Trustee be responsible for the act or omission of any other Trustee. The Trustees may take advice of counsel or other experts with respect to the meaning and operation of this Declaration and their duties as Trustees, and shall be under no liability for any act or omission in accordance with such advice or for failing to follow such advice. In discharging their duties, the Trustees, when acting in good faith, shall be entitled to rely upon the records, books and accounts of the Trust and upon reports made to the Trustees by any officer, employee, agent, consultant, accountant, attorney, investment adviser or other adviser, principal underwriter, expert, professional firm or independent contractor. The Trustees as such shall not be required to give any bond or surety or any other security for the performance of their duties. No provision of this Declaration shall protect any Trustee or officer of the Trust against any liability to the Trust or its Shareholders to which he would otherwise be subject by reason of his own willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office.

SECTION 4.3. INDEMNIFICATION. The Trustees may provide, whether in the By-Laws or by contract, vote or other action, for the indemnification by the Trust or by any Class or Series thereof of the Shareholders, Trustees, officers and employees of the Trust and of such other Persons as the Trustees in the exercise of their discretion may deem appropriate or desirable. Any such indemnification may be mandatory or permissive, and may be insured against by policies maintained by the Trust.

10

SECTION 4.4. NO DUTY OF INVESTIGATION. No purchaser, lender or other Person dealing with the Trustees or any officer, employee or agent of the Trust or a Class or Series thereof shall be bound to make any inquiry concerning the validity of any transaction purporting to be made by the Trustees or by said officer, employee or agent or be liable for the application of money or property paid, loaned, or delivered to or on the order of the Trustees or of said officer, employee or agent. Every obligation, contract, instrument, certificate, Share, other security or undertaking of the Trust or a Class or Series, and every other act or thing whatsoever executed in connection with the Trust shall be conclusively presumed to have been executed or done by the executors thereof only in their capacity as Trustees under this Declaration or in their capacity as officers, employees or agents of the Trust. Every written obligation, contract, instrument, certificate, Share, other security or undertaking of the Trust or a Class or Series made or issued by the Trustees may recite that the same is executed or made by them not individually, but as Trustees under the Declaration, and that the obligations of the Trust or a Class or Series thereof under any such instrument are not binding upon any of the Trustees or Shareholders individually, but bind only the Trust Property or the Trust Property of the applicable Class or Series, and may contain any further recital which they may deem appropriate, but the omission of any such recital shall not operate to bind the Trustees or Shareholders individually.

SECTION 4.5. RELIANCE ON RECORDS AND EXPERTS. Each Trustee, officer or employee of the Trust shall, in the performance of his duties, be fully and completely justified and protected with regard to any act or any failure to act resulting from reliance in good faith upon the records, books and accounts of the Trust or a Class or Series thereof, upon an opinion or other advice of legal counsel, or upon reports made or advice given to the Trust or a Class or Series thereof by any Trustee or any of the Trust's officers or employees or by the Investment Adviser, the Administrator, the Custodian, a Principal Underwriter, Transfer Agent, accountants, appraisers or other experts, advisers, consultants or professionals selected with reasonable care by the Trustees or officers of the Trust, regardless of whether the person rendering such report or advice may also be a Trustee, officer or employee of the Trust.

ARTICLE V

SHARES OF BENEFICIAL INTEREST

SECTION 5.1. SHARES OF BENEFICIAL INTEREST. The interest of the beneficiaries of the Trust initially shall be divided into common shares of beneficial interest of $.01 par value. The number of common shares authorized hereunder is unlimited. All shares issued, including, without limitation, those issued in connection with a dividend or distribution or a share split, shall be fully paid and nonassessable. The Trustees may, without Shareholder approval, authorize one or more Classes of Shares (which Classes may without Shareholder approval be divided by the Trustees into two or more Series), Shares of each such Class or Series having such preferences, voting powers and special or relative rights or privileges (including conversion rights, if any) as the Trustees may determine and as shall be set forth in a resolution adopted in accordance with the By-Laws. The number of Shares of each Class or Series authorized shall be unlimited except as the By-Laws may otherwise provide. The Trustees may from time to time divide or combine the Shares of any Class or Series into a greater or lesser number without thereby changing the proportionate beneficial interest in the Class or Series.

The ownership of Shares shall be recorded on the books of the Trust or a transfer or similar agent. No certificates certifying the ownership of Shares shall be issued except as the Trustees may otherwise determine from time to time. The Trustees may make such rules as they consider appropriate for the issuance of Share certificates, the transfer of Shares and similar matters. The record books of the Trust as kept by the Trust or any transfer or similar agent, as the case may be, shall be conclusive as to who are the Shareholders of each Class or Series and as to the number of Shares of each Class or Series held from time to time by each Shareholder. The Trustees may at any time discontinue the issuance of Share certificates and may, by written notice to each Shareholder, require the surrender of Share certificates to the Trust for cancellation. Such surrender and cancellation shall not affect the ownership of Shares in the Trust.

11

SECTION 5.2. VOTING POWERS. Subject to the voting powers of one or more Classes or Series, the Shareholders shall have power to vote only (i) with respect to the election of Trustees, (ii) for the removal of Trustees as provided for herein, (iii) with respect to any Investment Adviser as required by applicable law, (iv) with respect to any termination or amendment of this Trust, or with respect to certain transactions, to the extent and as provided in Article VIII, (v) to the same extent as the stockholders of a Massachusetts business corporation as to whether or not a court action, proceeding or claim should or should not be brought or maintained derivatively or as a class action on behalf of the Trust or the Shareholders, and (vi) with respect to such additional matters relating to the Trust as may be required by law, this Declaration, the By-Laws or any registration of the Trust with the Securities and Exchange Commission (or any successor agency) or any state, or as the Trustees may consider necessary or desirable. Each whole Share shall be entitled to one vote as to any matter on which it is entitled to vote and each fractional Share shall be entitled to a proportionate fractional vote. Notwithstanding any other provision of this Declaration, on any matter submitted to a vote of Shareholders, all Shares of the Trust then entitled to vote shall, except as otherwise provided in the By-Laws or required by applicable law, be voted in the aggregate as a single Class without regard to Classes or Series. There shall be no cumulative voting in the election of Trustees.

SECTION 5.3. RIGHTS OF SHAREHOLDERS. The ownership of the Trust Property of every description and the right to conduct any business of the Trust are vested exclusively in the Trustees, and the Shareholders shall have no interest therein other than the beneficial interest conferred by their Shares, and they shall have no right to call for any partition or division of any property, profits, rights or interests of the Trust or of any Class or Series nor can they be called upon to share or assume any losses of the Trust or of any Class or Series or suffer an assessment of any kind by virtue of their ownership of Shares. The Shares shall be personal property giving only the rights specifically set forth in this Declaration. The Shares shall not entitle the holder to preference, preemptive, appraisal, conversion or exchange rights, except as the Trustees may specifically determine with respect to any Class or Series.

Every Shareholder by virtue of having become a Shareholder shall be held to have expressly assented and agreed to the terms of this Declaration and the Bylaws and to have become a party hereto and thereto. The death of a Shareholder during the continuance of the Trust shall not operate to terminate the same nor entitle the representative of any deceased Shareholder to an accounting or to take any action in court or elsewhere against the Trust or the Trustees, but only to the rights of said decedent under this Trust.

SECTION 5.4. TRUST ONLY. It is the intention of the Trustees to create only the relationship of Trustee and beneficiary between the Trustees and each Shareholder from time to time. It is not the intention of the Trustees to create a general partnership, limited partnership, joint stock association, corporation, limited liability company, bailment or any form of legal relationship other than a Massachusetts business trust. Nothing in this Declaration shall be construed to make the Shareholders, either by themselves or with the Trustees, partners or members of a joint stock association.

SECTION 5.5. ISSUANCE OF SHARES. The Trustees in their discretion may, from time to time and without any authorization or vote of the Shareholders, issue Shares of any Class or Series, in addition to the then issued and Outstanding Shares, to such party or parties and for such amount and type of consideration, including cash or property, at such time or times and on such terms as the Trustees may deem appropriate or desirable, and may in such manner acquire other assets (including the acquisition of assets subject to, and in connection with the assumption of, liabilities) and businesses. In connection with any issuance of Shares, the Trustees may issue fractional Shares and reissue and resell full and fractional Shares held in the treasury. The Trustees may authorize the issuance of certificates of beneficial interest to evidence the ownership of

12

Shares. Shares held in the treasury shall not be voted nor shall such Shares be entitled to any dividends or other distributions declared with respect thereto. The Trustees in their discretion may also, from time to time and without any authorization or vote of the Shareholders, issue to the extent consistent with applicable law securities of the Trust convertible into Shares of the Trust and warrants to purchase securities of the Trust, in each case pursuant to such terms and under such conditions as the Trustees may specify in their discretion. Shares of any Class or Series, in addition to the then issued and outstanding Shares, and such warrants or convertible securities, may be issued to such party or parties and for such amount and type of consideration, including cash or property, at such time or times and on such terms as the Trustees may deem appropriate or desirable, and may in such manner acquire other assets (including the acquisition of assets subject to, and in connection with the assumption of, liabilities) and businesses. The officers of the Trust are severally authorized to take all such actions as may be necessary or desirable to carry out this
Section 5.5.

REDEMPTIONS AND REPURCHASES

SECTION 6.1. REDEMPTIONS AND REPURCHASES OF SHARES. From time to time the Trust may redeem or repurchase its Shares, all upon such terms and conditions as may be determined by the Trustees and subject to any applicable provisions of the 1940 Act. The Trust may require Shareholders to pay a withdrawal charge, a sales charge, or any other form of charge to the Trust, to the underwriter or to any other person designated by the Trustees upon redemption or repurchase of Trust Shares in such amount as shall be determined from time to time by the Trustees. The Trust may also charge a redemption or repurchase fee in such amount as may be determined from time to time by the Trustees.

SECTION 6.2 MANNER OF PAYMENT. Payment of Shares redeemed or repurchased may at the option of the Trustees or such officer or officers as they may duly authorize for the purpose, in their complete discretion, be made in cash, or in kind, or partially in cash and partially in kind. In case of payment in kind the Trustees, or their delegate, shall have absolute discretion as to what security or securities shall be distributed in kind and the amount of the same, and the securities shall be valued for purposes of distribution at the figure at which they were appraised in computing the net asset value of the Shares, provided that any Shareholder who cannot legally acquire securities so distributed in kind by reason of the prohibitions of the 1940 Act shall receive cash.

SECTION 6.3. INVOLUNTARY REDEMPTION. If the Trustees shall, at any time and in good faith, be of the opinion that direct or indirect ownership of Shares of any Class or Series or other securities of the Trust has or may become concentrated in any person to an extent which would disqualify the Trust as a regulated investment company under the Internal Revenue Code, then the Trustees shall have the power by lot or other means deemed equitable by them (i) to call for redemption by any such person a number, or principal amount, of Shares or other securities of the Trust sufficient to maintain or bring the direct or indirect ownership of Shares or other securities of the Trust into conformity with the requirements for such qualification and (ii) to refuse to transfer or issue Shares or other securities of the Trust to any person whose acquisition of the Shares or other securities of the Trust in question would result in such disqualification. The redemption shall be effected upon such terms and conditions as shall be determined by the Trustees.

The holders of Shares or other securities of the Trust shall upon demand disclose to the Trustees in writing such information with respect to direct and indirect ownership of Shares or other securities of the Trust as the Trustees deem necessary to comply with the provisions of the Internal Revenue Code, or to comply with the requirements of any other taxing authority.

The net asset value of each outstanding Share of the Trust or of any Class or Series thereof shall be determined on such days and at or as of such time or times as the Trustees may determine. Any reference in this Declaration to the time at which a determination of net asset value is made shall mean the time as of which the determination is made. The power and duty to determine and method of determination of net asset value may be delegated by the Trustees from time to time to the Investment Adviser, the Administrator, the Custodian, the Transfer Agent or such other Person or Persons as the Trustees may determine. The value of the assets of the Trust or any Class or Series thereof shall be determined in a manner authorized by the Trustees. From the total value of said assets, there shall be deducted all indebtedness, interest, taxes, payable or accrued, including estimated taxes on unrealized book profits, expenses and management charges accrued to the appraisal date, and all other items in the nature of liabilities which shall be deemed appropriate by the Trustees, as incurred by or allocated to the Trust or any Class or Series thereof. The resulting amount, which shall represent the total net assets of the Trust or Class or Series thereof, shall be divided by the number of Outstanding Shares of the Trust or Class or Series thereof at that time and the quotient so obtained shall be deemed to be the net asset value of the Shares of the Trust or Class or Series thereof. The Trust may declare a suspension of the determination of net asset value to the extent permitted by the 1940 Act. It shall not be a violation of any provision of this Declaration if Shares are sold, redeemed or repurchased by the Trust at a price other than one based on net asset value if the net asset value is affected by one or more errors inadvertently made in the pricing of portfolio securities or other investments or in accruing or allocating income, expenses, reserves or liabilities. No provision of this Declaration shall be construed to restrict or affect the right or ability of the Trust to employ or authorize the use of pricing services, appraisers or any other means, methods, procedures, or techniques in valuing the assets or calculating the liabilities of the Trust or any Class or Series thereof.

SECTION 7.2. DIVIDENDS AND DISTRIBUTIONS. (a) The Trustees may from time to time distribute ratably among the Shareholders of the Trust or of a Class or Series thereof such portion of the net earnings or profits, surplus (including paid-in surplus), capital (including paid-in capital), or assets of the Trust or such Class or Series held by the Trustees as they may deem appropriate or desirable. Such distributions may be made in cash, additional Shares or property (including without limitation any type of obligations of the Trust or Class or Series or any assets thereof), and the Trustees may distribute ratably among the Shareholders of the Trust or Class or Series thereof additional Shares of the Trust or Class or Series thereof issuable hereunder in such manner, at such times, and on such terms as the Trustees may deem appropriate or desirable. Such distributions may be among the Shareholders of the Trust or Class or Series thereof at the time of declaring a distribution or among the Shareholders of the Trust or Class or Series thereof at such other date or time or dates or times as the Trustees shall determine. The Trustees may always retain from the earnings or profits such amounts as they may deem appropriate or desirable to pay the expenses and liabilities of the Trust or a Class or Series thereof or to meet obligations of the Trust or a Class or Series thereof, together with such amounts as they may deem desirable to use in the conduct of its affairs or to retain for future requirements or extensions of the business or operations of the Trust or such Class or Series. The Trust may adopt and offer to Shareholders such dividend reinvestment plans, cash dividend payout plans or other distribution plans as the Trustees may deem appropriate or desirable. The Trustees may in their discretion determine that an account administration fee or other similar charge may be deducted directly from the income and other distributions paid on Shares to a Shareholder's account in any Class or Series.

(b) The Trustees may prescribe, in their absolute discretion, such bases and times for determining the amounts for the declaration and payment of dividends and distributions as they may deem necessary, appropriate or desirable.

14

(c) Inasmuch as the computation of net income and gains for federal income tax purposes may vary from the computation thereof on the books of account, the above provisions shall be interpreted to give the Trustees full power and authority in their absolute discretion to distribute for any fiscal year as dividends and as capital gains distributions, respectively, additional amounts sufficient to enable the Trust or a Class or Series thereof to avoid or reduce liability for taxes.

SECTION 7.3. POWER TO MODIFY FOREGOING PROCEDURES. Notwithstanding any provision contained in this Declaration, the Trustees may prescribe, in their absolute discretion, such other means, methods, procedures or techniques for determining the per Share net asset value of a Class or Series thereof or the income of the Class or Series thereof, or for the declaration and payment of dividends and distributions on any Class or Series.

ARTICLE VIII

DURATION; TERMINATION OF TRUST OR A
CLASS OR SERIES; MERGERS; AMENDMENTS

SECTION 8.1. DURATION. The Trust shall continue without limitation of time but subject to the provisions of this Article VIII. The death, declination, resignation, retirement, removal or incapacity of the Trustees, or any one of them, shall not operate to terminate or annul the Trust or to revoke any existing agency or delegation or authority pursuant to the terms of this Declaration or of the By-Laws.

SECTION 8.2. MERGER OR TERMINATION OF THE TRUST OR A SERIES OR A CLASS. The Trust may merge or consolidate with any other corporation, association, trust or other organization or may sell, lease or exchange all or substantially all of the Trust property, including its good will, upon such terms and conditions and for such consideration when and as authorized at a meeting of Shareholders called for the purpose by the affirmative vote of the holders of two-thirds of each Class and Series of Shares outstanding and entitled to vote (with each such class and series separately voting thereon as a separate Class or Series), or by an instrument or instruments in writing without a meeting, consented to by the holders of two-thirds of each Class and Series of Shares (with each such Class and Series separately consenting thereto as a separate Class or Series); provided, however, that if such merger, consolidation, sale, lease or exchange is recommended by the Trustees, the vote or written consent of the holders of a majority of the Shares outstanding and entitled to vote shall be sufficient authorization; and any such merger, consolidation, sale, lease or exchange shall be deemed for all purposes to have been accomplished under and pursuant to the statutes of the Commonwealth of Massachusetts. Upon making provision for the payment of all outstanding obligations, taxes and other liabilities, (whether accrued or contingent) of the Trust, the Trustees shall distribute the remaining assets of the Trust ratably among the holders of the outstanding Shares, except as may be otherwise provided by the Trustees with respect to any Class or Series of Shares thereof.

Subject to authorization by the Shareholders as indicated below in this paragraph, the Trust may at any time sell and convert into money all of the assets of the Trust, and, upon making provision for the payment of all outstanding obligations, taxes and other liabilities (whether accrued or contingent) of the Trust, the Trustees shall distribute the remaining assets of the Trust ratably among the holders of the outstanding Shares, except as may be otherwise provided by the Trustees with respect to any Class or Series of Shares. Such action shall first have been authorized at a meeting of Shareholders called for the purpose by the affirmative vote of the holders of two-thirds of each Class and Series of Shares outstanding and entitled to vote (with each such Class and Series separately voting thereon as a separate Class or Series), or by an instrument or instruments in writing without a meeting, consented to by the holders of two-thirds of each Class and Series of Shares

15

(with each such Class and Series separately consenting thereto as a separate Class or Series); provided, however, that if such action is recommended by the Trustees, the vote or written consent of the holders of a majority of the Shares outstanding and entitled to vote shall be sufficient authorization.

Upon completion of the distribution of the remaining proceeds or the remaining assets as provided in this section, the Trust shall terminate and the Trustees shall be discharged of any and all further liabilities and duties hereunder and the right, title and interest of all parties shall be cancelled and discharged.

SECTION 8.3. AMENDMENTS. The execution of an instrument setting forth the establishment and designation and the relative rights of any Class or Series of Shares in accordance with Section 5.1 hereof shall, without any authorization, consent or vote of the Shareholders, effect an amendment of this Declaration. Except as otherwise provided in this Section, if authorized by a majority of the Trustees and by vote of a majority of the outstanding voting securities of the Trust affected by the amendment (which voting securities shall, unless otherwise provided by the Trustees, vote together on such amendment as a single class), or by any larger vote which may be required by applicable law or this Declaration of Trust in any particular case, the Trustees may amend or otherwise supplement this Declaration. The Trustees may also amend this Declaration without the vote or consent of Shareholders to change the name of the Trust or to make such other changes as do not have a materially adverse effect on the rights or interests of Shareholders hereunder or if they deem it necessary to conform this Declaration to the requirements of applicable Federal laws or regulations or the requirements of the regulated investment company provisions of the Internal Revenue Code, but the Trustees shall not be liable for failing so to do.

No amendment may be made under this Section which shall amend, alter, change or repeal any of the provisions of Article VIII unless the amendment effecting such amendment, alteration, change or repeal shall receive the affirmative vote or consent of the holders of two-thirds of each Class and Series of Shares outstanding and entitled to vote (with each such Class and Series separately voting thereon on consenting thereto as a separate Class or Series). Such affirmative vote or consent shall be in addition to the vote or consent of the holders of Shares otherwise required by law or by any agreement between the Trust and any national securities exchange.

Nothing contained in this Declaration shall permit the amendment of this Declaration to impair the exemption from personal liability of the Shareholders, Trustees, officers, employees and agents of the Trust or to permit assessments upon Shareholders.

Notwithstanding any other provision hereof, until such time as a Registration Statement under the Securities Act of 1933, as amended, covering the first public offering of securities of the Trust shall have become effective, this Declaration may be terminated or amended in any respect by the affirmative vote of a majority of the Trustees or by an instrument signed by a majority of the Trustees.

SECTION 8.4. CERTAIN TRANSACTIONS. (a) Notwithstanding any other provision of this Declaration and subject to the exceptions provided in sub-section (d) of this Section 8.4, the types of transactions described in sub-section (c) of this
Section 8.4 shall require the affirmative vote or consent of the holders of seventy-five percent (75%) of each Class of Shares outstanding (with each such Class voting separately thereon), when a Principal Shareholder (as defined in sub-section (b) of this Section 8.4) is determined by the Trustees to be a party to the transaction. Such affirmative vote or consent shall be in addition to the vote or consent of the holders of Shares otherwise required by law or by the terms of any Class or Series, whether now or hereafter authorized, or by any agreement between the Trust and any national securities exchange.

(b) The term "Principal Shareholder" shall mean any Person which is the beneficial owner, directly or indirectly, of more than five percent (5%) of the Outstanding Shares of the Trust or of any Class and shall include any "affiliate" or "associate", as such terms are defined in Rule 12b-2 of the General Rules and Regulations under the Securities Exchange Act of 1934. For the purpose of this Section 8.4, in addition to the Shares which a Person beneficially owns directly, (a) a Person shall be deemed to be the beneficial owner of any Shares (i) which the Trustees determine it has the right to acquire pursuant to any agreement or upon exercise of conversion rights or warrants, or

16

otherwise (but excluding Share options granted by the Trust) or (ii) which the Trustees determine are beneficially owned, directly or indirectly (including Shares deemed owned through application of clause (i) above), by any other Person with which it or its "affiliate" or "associate" (as defined above) has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting or disposing of Shares, or which is its affiliate or associate, and (b) the outstanding Shares shall include Shares deemed owned through application of clauses (i) and (ii) above but shall not include any other Shares which are not at the time issued and outstanding but may be issuable pursuant to any agreement, or upon exercise of conversion rights or warrants, or otherwise.

(c) This Section 8.4 shall apply to the following transactions:

(i) The merger or consolidation of the Trust or any subsidiary of the Trust with or into any Principal Shareholder.

(ii) The issuance of any securities of the Trust to any Principal Shareholder for cash.

(iii) The sale, lease or exchange of all or any substantial part of the assets of the Trust to any Principal Shareholder (except assets determined by the Trustees to have 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 assets sold in the ordinary course of business).

(iv) The sale, lease or exchange to or with the Trust or any subsidiary thereof, in exchange for securities of the Trust, of any assets of any Principal Shareholder (except assets determined by the Trustees to have 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).

For purposes of this sub-section 8.4(c), the term "Principal Shareholder" shall include all subsidiaries, affiliates, associates, or other persons acting in concert with any Principal Shareholder.

(d) The provisions of this Section 8.4 shall not be applicable to (i) any of the transactions described in sub-section (c) of this Section 8.4 if the Trustees shall by resolution have approved a memorandum of understanding with such Principal Shareholder with respect to and substantially consistent with such transaction, or (ii) any such transaction with any Person of which a majority of the outstanding shares of all classes of stock normally entitled to vote in the election of directors is owned of record or beneficially by the Trust and its subsidiaries.

(e) The Trustees shall have the power to determine for the purposes of this
Section 8.4 on the basis of information known to the Trust, whether (i) a Person beneficially owns more than five percent (5%) of the outstanding Shares or is otherwise a Principal Shareholder, (ii) a Person is an "affiliate" or "associate" (as defined above) of another, (iii) the assets being acquired or leased to or by the Trust or any subsidiary thereof constitute a substantial part or the assets of the Trust and have an aggregate fair market value of less than $1,000,000, (iv) the memorandum of understanding referred to in sub-section
(d) hereof is substantially consistent with the transaction covered thereby, and
(v) the provisions of the Section 8.5 otherwise apply to any Person or transaction. Any such determination shall be conclusive and binding for all purposes of this Section 8.4.

17

SECTION 8.5. CONVERSION. Notwithstanding any other provisions of this Declaration, the conversion of the Trust from a "closed-end company" to an "open-end company," as those terms are defined in Section 5(a)(2) and 5(a)(1), respectively, of the 1940 Act shall require the affirmative vote or consent of the holders of two-thirds of each Class outstanding (with each Class separately voting thereon or consenting thereto as a separate Class). Such affirmative vote or consent shall be in addition to the vote or consent of the holders of the Shares otherwise required by law or by the terms of any Class or Series, whether now or hereafter authorized, or by any agreement between the Trust and any national securities exchange. However, if such conversion is recommended by at least 75% of the Trustees then in office, the vote or written consent of the holders of a majority of the outstanding voting securities of the Trust (which voting securities shall vote separately on the matter by class) shall be sufficient to authorize such conversion.

ARTICLE IX

MISCELLANEOUS

SECTION 9.1. USE OF THE WORDS "EATON VANCE". Eaton Vance Corp. (hereinafter referred to as "EVC"), which owns (either directly or through subsidiaries) all of the capital shares of the Investment Adviser of the Trust (or of the investment adviser of each of the investment companies referred to in the last paragraph of Section 2.9), has consented to the use by the Trust of the identifying words "Eaton Vance" in the name of the Trust. Such consent is conditioned upon the continued employment of EVC or a subsidiary or affiliate of EVC as Investment Adviser of the Trust or as the investment adviser of each of the investment companies referred to in the last paragraph of Section 2.9. As between the Trust and itself, EVC shall control the use of the name of the Trust insofar as such name contains the identifying words "Eaton Vance". EVC may from time to time use the identifying words "Eaton Vance" in other connections and for other purposes, including, without limitation, the names of other investment companies, trusts, corporations or businesses which it may manage, advise, sponsor or own or in which it may have a financial interest. EVC may require the Trust to cease using the identifying words "Eaton Vance" in the name of the Trust if EVC or a subsidiary or affiliate of EVC ceases to act as investment adviser of the Trust or as the investment adviser of each of the investment companies referred to in the last paragraph of Section 2.9.

SECTION 9.2. NOTICES. Notwithstanding any other provision of this Declaration, any and all notices to which any Shareholder may be entitled and any and all communications shall be deemed duly served or given if mailed, postage prepaid, addressed to any Shareholder of record at his last known address as recorded on the register of the Trust. If and to the extent consistent with applicable law, a notice of a meeting, an annual report, and any other communication to Shareholders need not be sent to a Shareholder (i) if an annual report and a proxy statement for two consecutive shareholder meetings have been mailed to such Shareholder's address and have been returned as undeliverable, (ii) if all, and at least two, checks (if sent by first class mail) in payment of distributions on Shares during a twelve-month period have been mailed to such Shareholder's address and have been returned as undeliverable or (iii) in any other case in which a proxy statement concerning a meeting of security holders is not required to be given pursuant to the Commission's proxy rules as from time to time in effect under the Securities Exchange Act of 1934, as amended. However, delivery of such proxy statements, annual reports and other communications shall resume if and when such Shareholder delivers or causes to be delivered to the Trust written notice setting forth such Shareholder's then current address.

SECTION 9.3. FILING OF COPIES, REFERENCES, HEADINGS AND COUNTERPARTS. The original or a copy of this instrument, of any amendment hereto and of each declaration of trust supplemental hereto, shall be kept at the office of the Trust. Anyone dealing with the Trust may rely on a certificate by a Trustee or

18

an officer of the Trust as to whether or not any such amendments or supplemental declarations of trust have been made and as to any matters in connection with the Trust hereunder, and, with the same effect as if it were the original, may rely on a copy certified by a Trustee or an officer of the Trust to be a copy of this instrument or of any such amendment hereto or supplemental declaration of trust.

In this instrument or in any such amendment or supplemental declaration of trust, references to this instrument, and all expressions such as "herein", "hereof", and "hereunder", shall be deemed to refer to this instrument as amended or affected by any such supplemental declaration of trust. Headings are placed herein for convenience of reference only and in case of any conflict, the text of this instrument, rather than the headings, shall control. This instrument may be executed in any number of counterparts each of which shall be deemed an original, but such counterparts shall constitute one instrument. A restated Declaration, integrating into a single instrument all of the provisions of the Declaration which are then in effect and operative, may be executed from time to time by a majority of the Trustees then in office and filed with the Massachusetts Secretary of State. A restated Declaration shall, upon execution, be conclusive evidence of all amendments and supplemental declarations contained therein and may thereafter be referred to in lieu of the original Declaration and the various amendments and supplements thereto.

SECTION 9.4. APPLICABLE LAW. The Trust set forth in this instrument is made in The Commonwealth of Massachusetts, and it is created under and is to be governed by and construed and administered according to the laws of said Commonwealth. The Trust shall be of the type commonly called a Massachusetts business trust, and without limiting the provisions hereof, the Trust may exercise all powers which are ordinarily exercised by such a trust.

SECTION 9.5. PROVISIONS IN CONFLICT WITH LAW OR REGULATIONS. (a) The provisions of this Declaration are severable, and if the Trustees shall determine, with the advice of legal counsel, that any of such provisions is in conflict with the 1940 Act, the Internal Revenue Code of 1986 or with other applicable laws and regulations, the conflicting provision shall be construed in such a manner consistent with such law as may most closely reflect the intention of the offending provision; provided, however, that such determination shall not affect any of the remaining provisions of this Declaration or render invalid or improper any action taken or omitted prior to such determination.

(b) If any provision of this Declaration shall be held invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall attach only to such provision in such jurisdiction and shall not in any manner affect such provision in any other jurisdiction or any other provision of this Declaration in any jurisdiction.

ARTICLE IV

Meetings of Shareholders

SECTION 1. MEETINGS. Meetings of shareholders, at which the shareholders shall elect Trustees and transact such other business as may properly come before the meeting, shall be held annually so long as required by the American Stock Exchange, New York Stock Exchange or such other exchange or trading system on which shares are principally traded. Meetings of the shareholders (or any class or series) may be called at any time by the President, and shall be called by the President or the Secretary at the request, in writing or by resolution, of a majority of the Trustees, or at the written request of the holder or holders of twenty-five percent (25%) or more of the total number of the then issued and outstanding shares of the Trust entitled to vote at such meeting. Any such request shall state the purposes of the proposed meeting.

SECTION 2. PLACE OF MEETINGS. Meetings of the shareholders shall be held at the principal place of business of the Trust in Boston, Massachusetts, unless a different place within the United States is designated by the Trustees and stated as specified in the respective notices or waivers of notice with respect thereto.

SECTION 3. NOTICE OF MEETINGS. Notice of all meetings of the shareholders, stating the time, place and the purposes for which the meetings are called, shall be given by the Secretary to each shareholder entitled to vote thereat, and to each shareholder who under the By-Laws is entitled to such notice, by delivering (by electronic, telephonic, computerized or other alternative means as may be approved by resolutions adopted by the trustees, which authorization is received not more than six months before delivery of such notice) or mailing, postage paid, addressed to such address as it appears upon the books of the Trust, at least ten days no more than ninety days before the time fixed for the meeting, and the person given such notice shall make an affidavit with respect thereto. If any shareholder shall have failed to inform the Trust of his address, no notice need be sent to him. No notice need be given to any shareholder if a written waiver of notice, executed before or after the meeting by the shareholder or his attorney thereunto authorized, is filed with the records of the meeting.

SECTION 4. QUORUM. Except as otherwise provided by law, to constitute a quorum for the transaction of any business at any meeting of shareholders, there must be present, in person or by proxy, holders of a majority of the total number of shares of the then issued and outstanding shares of the Trust entitled to vote at such meeting; provided that if a class (or series) of shares is entitled to vote as a separate class (or series) on any matter, then in the case of that matter a quorum shall consist of the holders of a majority of the total number of shares of the then issued and outstanding shares of that class (or series) entitled to vote at the meeting. Shares owned directly or indirectly by the Trust, if any, shall not be deemed outstanding for this purpose.

If a quorum, as above defined, shall not be present for the purpose of any vote that may properly come before any meeting of shareholders at the time and place of any meeting, the shareholders present in person or by proxy and entitled to vote at such meeting on such matter holding a majority of the shares present and entitled to vote on such matter may by vote adjourn the meeting from time to time to be held at the same place without further notice than by announcement to be given at the meeting until a quorum, as above defined, entitled to vote on such matter, shall be present, whereupon any such matter may be voted upon at the meeting as though held when originally convened.

3

SECTION 5. VOTING. At each meeting of the shareholders every shareholder of the Trust shall be entitled to one vote in person or by proxy for each of the then issued and outstanding shares of the Trust then having voting power in respect of the matter upon which the vote is to be taken, standing in his name on the books of the Trust at the time of the closing of the transfer books for the meeting, or, if the books be not closed for any meeting, on the record date fixed as provided in Section 4 of Article VI of these By-Laws for determining the shareholders entitled to vote at such meeting, or if the books be not closed and no record date be fixed, at the time of the meeting. The record holder of a fraction of a share shall be entitled in like manner to corresponding fraction of a vote. Notwithstanding the foregoing, the Trustees may, in connection with the establishment of any class (or series) of shares or in proxy materials for any meeting of shareholders or in other solicitation materials or by vote or other action duly taken by them, establish conditions under which the several classes (or series) shall have separate voting rights or no voting rights.

All elections of Trustees shall be conducted in any manner approved at the meeting of the shareholders at which said election is held, and shall be by ballot if so requested by any shareholder entitled to vote thereon. The persons receiving the greatest number of votes shall be deemed and declared elected. Except as otherwise required by law or by the Declaration of Trust or by these By-Laws, all matters shall be decided by a majority of the votes cast, as hereinabove provided, by persons entitled to vote thereon.

SECTION 6. PROXIES. Any shareholder entitled to vote upon any matter at any meeting of the shareholders may so vote by proxy, provided that such proxy to act is authorized to act by (i) a written instrument, dated not more than six months before the meeting and executed either by the shareholder or by his or her duly authorized attorney in fact (who may be so authorized by a writing or by any non-written means permitted by the laws of The Commonwealth of Massachusetts) or (ii) such electronic, telephonic, computerized or other alternative means as may be approved by a resolution adopted by the Trustees, which authorization is received not more than six months before the initial session of the meeting. Proxies shall be delivered to the Secretary of the Trust or other person responsible for recording the proceedings before being voted. A proxy with respect to shares held in the name of two or more persons shall be valid if executed by one of them unless at or prior to exercise of such proxy the Trust receives a specific written notice to the contrary from any one of them. Unless otherwise specifically limited by their terms, proxies shall entitle the holder thereof to vote at any adjournment of a meeting. A proxy purporting to be exercised by or on behalf of a shareholder shall be deemed valid unless challenged at or prior to its exercise and the burden of proving invalidity shall rest on the challenger. At all meetings of the shareholders, unless the voting is conducted by inspectors, all questions relating to the qualifications of voters, the validity of proxies, and the acceptance or rejection of votes shall be decided by the chairman of the meeting.

SECTION 7. CONSENTS. Any action which may be taken by shareholders may be taken without a meeting if a majority of shareholders entitled to vote on the matter (or such larger proportion thereof as shall be required by law, the Declaration or these By-Laws for approval of such matter) consent to the action in writing and the written consents are filed with the records of the meetings of shareholders. Such consents shall be treated for all purposes as a vote taken at a meeting of shareholders.

(1) Nominations of persons for election of the Board of Trustees and the proposal of business to be considered by the shareholders may be made at an annual meeting of shareholders (a) pursuant to the notice of meeting described in Section 3 of this Article of these By-Laws; (b) by or at the direction of the Board of Trustees; or (c) by any shareholder of the Trust who was a shareholder of record at the time of giving of notice provided for in Section 3 of this Article of these By-Laws, who is entitled to vote at the meeting and who complied with the notice provisions set forth in this Section 8.

(2) For nominations or other business properly to be brought before an annual meeting by a shareholder pursuant to clause (c) of paragraph (A)(1) of this Section 8, the shareholder must have given timely notice thereof in writing to the Secretary of the Trust and such other business must be a proper matter for shareholder action. To be timely, a shareholder's notice shall be delivered to the Secretary at the principal executive offices of the Trust not later than the close of business on the ninetieth day nor earlier than the close of business on the one hundred-twentieth day prior to the first anniversary of the preceding year's annual meeting; provided, however, that in the event that the date of the annual meeting is more than thirty days before or more than sixty days after such anniversary date, notice by the shareholder to be timely must be so delivered not earlier than the close of business on the later of the ninetieth day prior to such annual meeting or the tenth day following the day on which public announcement of the date of such meeting is first made. In no event, shall the public announcement of an adjournment of an annual meeting commence a new time period for the giving of a shareholder's notice as described above. Such shareholder's notice shall set forth (a) as to each person whom the shareholder proposes to nominate for election or reelection as a Trustee all information relating to such person that is required to be disclosed in solicitations of proxies for election of trustees/directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the "Exchange Act") and Rule 14a-11 thereunder (including such person's written consent to being named in the proxy statement as a nominee and to serving as a Trustee if elected); (b) as to any other business that the shareholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting and any material interest in such business of such shareholder and the beneficial owner, if any, on whose behalf the proposal is made; and (c) as to the shareholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made
(i) the name and address of such shareholder, as they appear on the Trust's books, and of such beneficial owner and (ii) the class/series and number of shares of the Trust which are owned beneficially and of record by such shareholder and such beneficial owner.

(3) Notwithstanding anything in the second sentence of paragraph (A)(2) of this Section 8 to the contrary, in the event that the number of Trustees to be elected to the Board of Trustees is increased and there is no public announcement naming all of the nominees for Trustee or specifying the size of the increased Board of Trustees made by the Trust at least one hundred days prior to the first anniversary of the preceding year's annual meeting, a shareholder's notice required by this Section 8 shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the Trust not later than the close of business on the tenth day following the day on which such public announcement is first made by the Trust.

5

(B) SPECIAL MEETINGS OF SHAREHOLDERS. Only such business shall be conducted by a special meeting of shareholders as shall have been brought before the meeting pursuant to the Trust's notice of meeting. Nominations of persons for election to the Board of Trustees may be made at a special meeting of shareholders at which Trustees are to be elected pursuant to the Trust's notice of meeting (1) by or at the direction of the Board of Trustees or (2) by any shareholder of the Trust who is a shareholder of record at the time of giving of notice provided for in this Section 8, who shall be entitled to vote at the meeting and who complies with the notice procedures set forth in this Section 8. In the event the Trust calls a special meeting of shareholders for the purpose of electing one or more Trustees to the Board of Trustees, any such shareholder may nominate a person or persons (as the case may be), for election to such position(s) as specified in the Trust's notice of meeting, if the shareholder's notice required by paragraph (A)(2) of this Section 8 shall be delivered to the Secretary at the principal executive offices of the Trust not earlier than the close of business on the one hundred-twentieth day prior to such special meeting and not later than the close of business on the later of the ninetieth day prior to such special meeting or the tenth day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Trustees to be elected at such meeting. In no event, shall the public announcement or adjournment of a special meeting commence a new time period for the giving of a shareholder's notice as described above.

(C) GENERAL. (1) Only such persons who are nominated in accordance with the procedures set forth in this Section 8 shall be eligible to serve as Trustees and only such business shall be conducted at a meeting of shareholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 8. Except as otherwise provided by law, the Declaration of Trust or these By-Laws, the Chairman (or such other officer presiding at the meeting) shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made, or proposed, as the case may be, in accordance with the procedures set forth in this Section 8 and, if any proposed nomination or business is not in compliance with this Section 8, to declare that such defective proposal or nomination shall be disregarded.

(2) For purposes of this Section 8, "public announcement" shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Trust with the Securities and Exchange Commission (the "Commission") pursuant to
Section 13, 14 or 15(d) of the Exchange Act.

(3) Notwithstanding the foregoing provisions of this Section 8, a shareholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section 8. Nothing in this Section 8 shall be deemed to affect any rights of (a) shareholders to request inclusion of proposals in the Trust's proxy statement pursuant to Rule 14a-8 under the Exchange Act or (b) the holders of any class of preferred shares of beneficial interest to elect Trustees under specified circumstances.

Trustees Meetings

SECTION 1. MEETINGS. The Trustees may in their discretion provide for regular or stated meetings of the Trustees. Meetings of the Trustees other than regular or stated meetings shall be held whenever called by the Chairman, President or by any other Trustee at the time being in office. Any or all of the Trustees may participate in a meeting by means of a conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other at the same time, and participation by such means shall constitute presence in person at a meeting.

SECTION 2. NOTICES. Notice of regular or stated meetings need not be given. Notice of the time and place of each meeting other than regular or stated meeting shall be given by the Secretary or by the Trustee calling the meeting and shall be mailed to each Trustee at least two days before the meeting, or shall be telegraphed, cabled, or wirelessed to each Trustee at his business address or personally delivered to him at least one day before the meeting. Such notice may, however, be waived by all the Trustees. Notice of a meeting need not be given to any Trustee if a written waiver of notice, executed by him before or after the meeting, is filed with the records of the meeting, or to any Trustee who attends the meeting without protesting prior thereto or at its commencement the lack of notice to him. A notice or waiver of notice need not specify the purpose of any special meeting.

SECTION 3. CONSENTS. Any action required or permitted to be taken at any meeting of the Trustees may be taken by the Trustees without a meeting if a written consent thereto is signed by all the Trustees and filed with the records of the Trustees' meetings. A Trustee may deliver his consent to the Trust by facsimile machine or other graphic communication equipment. Such consent shall be treated as a vote at a meeting for all purposes.

SECTION 4. PLACE OF MEETINGS. The Trustees may hold their meetings within or without The Commonwealth of Massachusetts.

SECTION 5. QUORUM AND MANNER OF ACTING. A majority of the Trustees in office shall be present in person at any regular stated or special meeting of the Trustees in order to constitute a quorum for the transaction of business at such meeting and (except as otherwise required by the Declaration of Trust, by these By-Laws or by statute) the act of a majority of the Trustees present at any such meeting, at which a quorum is present, shall be the act of the Trustees. In the event that action is to be taken with respect to the death, declination, resignation, retirement, removal or incapacity of one or more Trustees, a quorum for the transaction of such business and any other business conducted at such meeting and (except as otherwise required by the Declaration of Trust, by these By-Laws or by statute) shall be a majority of the remaining Trustees then in office. In the absence of quorum, a majority of the Trustees present may adjourn the meeting from time to time until a quorum shall be present. Notice of any adjourned meeting need not be given.

ARTICLE VI

Shares of Beneficial Interest

SECTION 1. CERTIFICATES FOR SHARES OF BENEFICIAL INTEREST. Certificates for shares of beneficial interest of any class of shares of the Trust, if issued, shall be in such form as shall be approved by the Trustees. They shall be signed by, or in the name of, the Trust by the President and by the Treasurer and may, but need not be, sealed with seal of the Trust; provided, however, that where such certificate is signed by a transfer agent or a transfer clerk acting on behalf of the Trust or a registrar other than a Trustee, officer or employee of the Trust, the signature of the President or Treasurer and the seal may be facsimile. In case any officer or officers who shall have signed, or whose facsimile signature or signatures shall have been used on any such certificate or certificates, shall cease to be such officer or officers of the Trust whether because of death, resignation or otherwise, before such certificate or certificates shall have been delivered by the Trust, such certificate or certificates may nevertheless be adopted by the Trust and be issued and delivered as though the person or persons who signed such certificate or certificates or whose facsimile signatures shall have been used thereon had not ceased to be such officer or officers of the Trust.

SECTION 2. TRANSFER OF SHARES. Transfers of shares of beneficial interest of any shares of the Trust shall be made only on the books of the Trust by the owner thereof or by his attorney thereunto authorized by a power of attorney duly executed and filed with the Secretary or a transfer agent, and only upon the surrender of any certificate or certificates for such shares. The Trust shall not impose any restrictions upon the transfer of the shares of the Trust, but this requirement shall not prevent the charging of customary transfer agent fees.

SECTION 3. TRANSFER AGENT AND REGISTRAR; REGULATIONS. The Trust shall, if and whenever the Trustees shall so determine, maintain one or more transfer offices or agencies, each in the charge of a transfer agent designated by the Trustees, where the shares of beneficial interest of the Trust shall be directly transferable. The Trust shall, if and whenever the Trustees shall so determine, maintain one or more registry offices, each in the charge of a registrar designated by the Trustees, where such shares shall be registered, and no certificate for shares of the Trust in respect of which a transfer agent and/or registrar shall have been designated shall be valid unless countersigned by such transfer agent and/or registered by such registrar. The principal transfer agent may be located within or without the Commonwealth of Massachusetts and shall have charge of the stock transfer books, lists and records, which shall be kept within or without Massachusetts in an office which shall be deemed to be the stock transfer office of the Trust. The Trustees may also make such additional rules and regulations as it may deem expedient concerning the issue, transfer and registration of certificates for shares of the Trust.

SECTION 4. CLOSING OF TRANSFER BOOKS AND FIXING RECORD DATE. The Trustees may fix in advance a time which shall be not more than seventy-five days before the date of any meeting of shareholders, or the date for the payment of any dividend or the making or any distribution to shareholders or the last day on which the consent or dissent of shareholders may be effectively expressed for any purpose, as the record date for determining the shareholders having the right to notice of and to vote at such meeting, and any adjournment thereof, or the right to receive such dividend or distribution or the right to give such consent or dissent, and in such case only shareholders of record on such record date shall have such right, notwithstanding any transfer of shares on the books of the Trust after the record date. The Trustees may, without fixing such record date, close the transfer books for all or any part of such period for any of the foregoing purposes.

SECTION 5. LOST, DESTROYED OR MUTILATED CERTIFICATES. The holder of any shares of the Trust shall immediately notify the Trust of any loss, destruction or mutilation of the certificate therefor, and the Trustees may, in their discretion, cause a new certificate or certificates to be issued to him, in case of mutilation of the certificate, upon the surrender of the mutilated certificate, or, in case of loss or destruction of the certificate, upon satisfactory proof of such loss or destruction and, in any case, if the Trustees shall so determine, upon the delivery of a bond in such form and in such sum and with such surety or sureties as the Trustees may direct, to indemnify the Trust against any claim that may be made against it on account of the alleged loss or destruction of any such certificate.

SECTION 6. RECORD OWNER OF SHARES. The Trust shall be entitled to treat the person in whose name any share of the Trust is registered on the books of the Trust as the owner thereof, and shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person.

ARTICLE VII

ARTICLE X

Principal Custodian and Sub-custodians

SECTION 1. PRINCIPAL CUSTODIAN. The following provisions shall apply to the employment of the principal Custodian pursuant to the Declaration of Trust:

(A) The Trust may employ the principal Custodian:

(1) To hold securities owned by the Trust and deliver the same upon written order or oral order, if confirmed in writing, or by such electro-mechanical or electronic devices as are agreed to by the Trust and such Custodian;

(2) To receive and receipt for any moneys due to the Trust and deposit the same in its own banking department or, as the Trustees may direct, in any bank, trust company or banking institution approved by such Custodian, provided that all such deposits shall be subject only to the draft or order of such Custodian; and

(3) To disburse such funds upon orders or vouchers.

(B) The Trust may also employ such Custodian as its agent:

(1) To keep the books and accounts of the Trust and furnish clerical and accounting services; and

(2) To compute the net asset value per share in the manner approved by the Trust.

(C) All of the foregoing services shall be performed upon such basis of compensation as may be agreed upon between the Trust and the principal Custodian. If so directed by vote of the holders of a majority of the outstanding shares of Trust, the principal Custodian shall deliver and pay over all property of the Trust held by it as specified in such vote.

(D) In case of the resignation, removal or inability to serve of any such Custodian, the Trustees shall promptly appoint another bank or trust company meeting the requirements of the Declaration of Trust as successor principal Custodian. The agreement with the principal Custodian shall provide that the retiring principal Custodian shall, upon receipt of notice of such appointment, deliver the funds and property of the Trust in its possession to and only to such successor, and that pending appointment of a successor principal Custodian, or a vote of the shareholders to function without a principal Custodian, the principal Custodian shall not deliver funds and property of the Trust to the Trustees, but may deliver them to a bank or trust company doing business in Boston, Massachusetts, of its own selection, having an aggregate capital, surplus and undivided profits, as

10

shown by its last published report, of not less than $2,000,000, as the property of the Trust to be held under terms similar to those on which they were held by the retiring principal Custodian.

SECTION 2. SUB-CUSTODIAN. The Trust may also authorize the principal Custodian to employ one or more sub-custodians from time to time to perform such of the acts and services of the Custodian and upon such terms and conditions as may be agreed upon between the Custodian and sub-custodian.

SECTION 3. SECURITIES DEPOSITORIES, ETC. Subject to such rules, regulations and orders as the Commission may adopt, the Trust may authorize or direct the principal Custodian or any sub-custodian to deposit all or any part of the securities in or with one or more depositories or clearing agencies or systems for the central handling of securities or other book-entry systems approved by the Trust, or in or with such other persons or systems as may be permitted by the Commission, or otherwise in accordance with the Act, pursuant to which all securities of any particular class or series of any issuer deposited within the system are treated as fungible and may be transferred or pledged by bookkeeping entry without physical delivery of such securities, provided that all such deposits shall be subject to withdrawal only upon the order of the Trust or the principal Custodian or the sub-custodian. The Trust may also authorize the deposit in or with one or more eligible foreign custodians (or in or with one or more foreign depositories, clearing agencies or systems for the central handling of securities) of all or part of the Trust's foreign assets, securities, cash and cash equivalents in amounts reasonably necessary to effect the Trust's foreign investment transactions, in accordance with such rules, regulations and orders as the Commission may adopt.

ARTICLE XI

Limitation of Liability and Indemnification

SECTION 1. LIMITATION OF LIABILITY. Provided they have exercised reasonable care and have acted under the reasonable belief that their actions are in the best interest of the Trust, the Trustees shall not be responsible for or liable in any event for neglect or wrongdoing of them or any officer, agent, employee or investment adviser of the Trust, but nothing contained in the Declaration of Trust or herein shall protect any Trustee against any liability to which he would otherwise be subject by reason of wilful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office.

SECTION 2. INDEMNIFICATION OF TRUSTEES AND OFFICERS. The Trust shall indemnify each person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or has been a Trustee, officer, employee or agent of the Trust, or is or has been serving at the request of the Trust as a Trustee, director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding, provided that:

(a) such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Trust,

(b) with respect to any criminal action or proceeding, he had no reasonable cause to believe his conduct was unlawful,

11

(c) unless ordered by a court, indemnification shall be made only as authorized in the specific case upon a determination that indemnification of the Trustee, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in subparagraphs (a) and (b) above and (e) below, such determination to be made based upon a review of readily available facts (as opposed to a full trial-type inquiry) by (i) vote of a majority of the Disinterested Trustees acting on the matter (provided that a majority of the Disinterested Trustees then in office act on the matter) or (ii) by independent legal counsel in a written opinion,

(d) in the case of an action or suit by or in the right of the Trust to procure a judgment in its favor, no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable for negligence or misconduct in the performance of his duty to the Trust unless and only to the extent that the court in which such action or suit is brought, or a court of equity in the county in which the Trust has its principal office, shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, he is fairly and reasonably entitled to indemnify for such expenses which such court shall deem proper, and

(e) no indemnification or other protection shall be made or given to any Trustee or officer of the Trust against any liability to the Trust or to its security holders to which he would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office.

Expenses (including attorneys' fees) incurred with respect to any claim, action, suit or proceeding of the character described in the preceding paragraph shall be paid by the Trust in advance of the final disposition thereof upon receipt of an undertaking by or on behalf of such person to repay such amount unless it shall ultimately be determined that he is entitled to be indemnified by the Trust as authorized by this Article, provided that either:

(1) such undertaking is secured by a surety bond or some other appropriate security provided by the recipient, or the Trust shall be insured against losses arising out of any such advances; or

(2) a majority of the Disinterested Trustees acting on the matter (provided that a majority of the Disinterested Trustees act on the matter) or an independent legal counsel in a written opinion shall determine, based upon a review of readily available facts (as opposed to a full trial-type inquiry), that there is reason to believe that the recipient ultimately will be found entitled to indemnification.

As used in this Section 2, a "Disinterested Trustee" is one who is not (i) an "Interested Person," as defined in the Act, of the Trust (including anyone who has been exempted from being an "Interested Person" by any rule, regulation, or order of the Commission), or (ii) involved in the claim, action, suit or proceeding.

12

The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Trust, or with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

SECTION 3. INDEMNIFICATION OF SHAREHOLDERS. In case any shareholder or former shareholder shall be held to be personally liable solely by reason of his being or having been a shareholder and not because of his acts or omissions or for some other reason, the shareholder or former shareholder (or his heirs, executors, administrators or other legal representatives, or in the case of a corporation or other entity, its corporate or other general successor) shall be entitled out of the Trust estate to be held harmless from and indemnified against all loss and expense arising from such liability. The Trust shall, upon request by the shareholder, assume the defense of any claim made against any shareholder for any act or obligation of the Trust and satisfy any judgment thereon. A holder of shares of a series shall be entitled to indemnification hereunder only out of assets allocated to that series.

ARTICLE XII

Report to Shareholders

SECTION 1. REPORTS TO SHAREHOLDERS. The Trustees shall at least semi-annually transmit by written, electronic, computerized or other alternative means to the shareholders a written financial report of the transactions of the Trust including financial statements which shall at least annually be certified by independent public accountants.

ARTICLE XIII

Amendments

SECTION 1. AMENDMENTS. These By-Laws may be amended at any meeting of the Trustees by a vote of a majority of the Trustees then in office; provided, however, that any provision of Article XI may be amended only by a two-thirds vote.
