EATON VANCE SENIOR INCOME TRUST

Eaton Vance Senior Income Trust (the "Trust") is a newly organized, non-diversified, closed-end management investment company. The Trust's investment objective is to provide a high level of current income, consistent with the preservation of capital, by investing primarily in senior secured floating rate loans ("Senior Loans"). Investment in such floating rate instruments is expected to minimize changes in the underlying principal value of the Senior Loans, and therefore the Trust's net asset value, resulting from changes in market interest rates. Nevertheless, the Trust's net asset value and distribution rate will vary, and may be affected by several factors, including changes in the credit quality of the borrowers underlying Senior Loans. Fluctuations in net asset value may be magnified as a result of the Trust's use of leverage. An investment in the Trust may not be appropriate for all investors and there is no assurance that the Trust will achieve its investment objective. See "Investment Objective, Policies and Risks."

Senior Loans are made to corporations, partnerships and other business entities ("Borrowers") which operate in various industries and geographical regions. Senior Loans pay interest at rates which are redetermined periodically on the basis of a floating base lending rate plus a premium. Senior Loans hold the most senior position in the capital structure of the Borrower, are secured with specific collateral and will have a claim on the assets of the Borrower that is senior to that of subordinated debt, preferred stock and common stock of the Borrower. Although Senior Loans have the most senior position in a Borrower's capital structure and are secured by specific collateral, they are typically of below investment grade quality and may have below investment grade ratings, which ratings are associated with securities having speculative characteristics. Because of the protective features of Senior Loans, the Adviser believes, based on its experience, that these ratings do not necessarily reflect the true risk of loss of principal or interest on a Senior Loan. The Trust offers investors the opportunity to receive current income through a professionally managed portfolio of Senior Loans, which is normally accessible only to financial institutions and large corporate and institutional investors and is not widely available to individual investors.

The Trust's investment adviser is Eaton Vance Management (the "Adviser" or "Eaton Vance"). The Adviser was one of the first investment advisers to manage a portfolio of Senior Loans in a publicly offered investment company, and has done so continuously since 1989. (continued on the following page)

IN CONNECTION WITH THIS OFFERING, THE UNDERWRITERS MAY OVER-ALLOT OR EFFECT TRANSACTIONS WHICH STABILIZE OR MAINTAIN THE MARKET PRICE OF THE SHARES OF THE TRUST AT A LEVEL ABOVE THAT WHICH MIGHT OTHERWISE PREVAIL IN THE OPEN MARKET.

(continued from the cover page)

The Trust is offering shares of beneficial interest, par value $0.01 per share ("Shares"). Prior to this offering, there has been no market for the Shares. The Shares have been approved for listing, subject to notice of issuance, on the New York Stock Exchange under the symbol "EVF." The shares of closed-end investment companies, such as the Trust, have frequently traded at a discount to their net asset values. Investors in this offering should note that the Shares may likewise trade at a discount to net asset value. This risk may be greater for investors who sell their Shares in a relatively short period after completion of the public offering.

The Trust expects to utilize financial leverage through borrowings, including the issuance of debt securities, the issuance of preferred shares or through other transactions, such as reverse repurchase agreements. The Trust intends to utilize financial leverage in an amount up to 33 1/3% of its total assets (including the amount obtained through leverage). The Trust intends to utilize leverage if it is expected to result in higher income to Shareholders over time. Use of financial leverage creates an opportunity for increased income but, at the same time, creates special risks. There can be no assurance that a leveraging strategy will be successful. SEE "INVESTMENT OBJECTIVE, POLICIES AND RISKS -- USE OF LEVERAGE AND RELATED RISKS" AND "DESCRIPTION OF CAPITAL STRUCTURE."

This Prospectus sets forth concisely information that a prospective investor should know before investing in the Shares of the Trust. Please read and retain this Prospectus for future reference.

                                 business entities ("Borrowers") which operate
                                 in various industries and geographical regions.
                                 Senior Loans pay interest at rates which are
                                 redetermined periodically by reference to a
                                 base lending rate, such as the London Inter-
                                 Bank Offered Rate ("LIBOR"), plus a premium. In
                                 normal market conditions, at least 80% of the
                                 Trust's total assets will be invested in
                                 interests in Senior Loans. It is anticipated
                                 that the proceeds of the Senior Loans in which
                                 the Trust will acquire interests primarily will
                                 be used to finance leveraged buyouts,
                                 recapitalizations, mergers, acquisitions and
                                 stock repurchases and, to a lesser extent, to
                                 finance internal growth and for other corporate
                                 purposes of Borrowers.

Although Senior Loans have the most senior position in a Borrower's capital structure and are secured by specific collateral, they are typically of below investment grade quality and may have below investment grade ratings, which ratings are associated with securities having speculative characteristics. Because of the protective features of Senior Loans, the Adviser believes, based on its experience, that these ratings do not necessarily reflect the true risk of loss of principal or interest on a Senior Loan. For example, the Adviser believes that Senior Loans tend to have more favorable loss recovery rates as compared to most other types of below investment grade quality debt obligations. Accordingly, the Adviser generally does not take ratings into account when determining whether to invest in a Senior Loan and, in any event, does not view ratings as a determinative factor in its investment decisions. Investing in Senior Loans does, however, involve investment risk, and some Borrowers default on their Senior Loan payments. The Trust attempts to manage these risks through portfolio diversification and ongoing analysis and monitoring of Borrowers. As a result, the Trust is highly dependent on the Adviser's credit analysis abilities.

The Trust may invest up to 20% of its total assets in: loan interests which are not secured by any, or that have lower than a senior claim on, collateral; other income producing securities such as investment and non-investment grade corporate debt securities and U.S. government and U.S. dollar-denominated foreign government or supranational debt securities (subject to the limit that not more than 10% of the Trust's total assets may have a fixed rate of interest); and warrants and equity securities acquired in connection with its investments in Senior Loans. The Trust may also engage in lending of its securities, repurchase agreements, reverse repurchase agreements and, for hedging and risk management purposes, certain derivative transactions. See "Investment Objective, Policies and Risks."

LISTING.......................   The Shares have been approved for listing,
                                 subject to notice of issuance, on the New York
                                 Stock Exchange under the symbol "EVF."


LEVERAGE......................   The Trust expects to utilize financial leverage
                                 through borrowings, including the issuance of
                                 debt securities, or the issuance of preferred
                                 shares or through other transactions, such as
                                 reverse repurchase agreements, which have the
                                 effect of financial leverage. The Trust intends
                                 to utilize financial leverage in an amount up
                                 to 33 1/3% of its total assets (including the
                                 amount obtained through leverage). The Trust
                                 generally will not utilize leverage if it
                                 anticipates that it would result in a lower
                                 return to Shareholders over time. Use of
                                 financial leverage creates an opportunity for
                                 increased income for Shareholders but, at the
                                 same time, creates special risks (including the
                                 likelihood of greater volatility of net asset
                                 value and market price of the Shares), and
                                 there can be no assurance that a leveraging
                                 strategy will be successful during any period
                                 in which it is employed. Because leverage
                                 achieved through borrowings is expected to be
                                 based on a floating rate of interest that
                                 fluctuates similarly to the floating rate on
                                 Senior Loans in the Trust's

                                        2

                                 portfolio, the Adviser believes that market
                                 interest rate fluctuations should not adversely
                                 affect returns on the Senior Loans obtained
                                 with the proceeds of such borrowings. See
                                 "Investment Objective, Policies and
                                 Risks -- Use of Leverage and Related Risks."

INVESTMENT ADVISER AND

  ADMINISTRATOR...............   Eaton Vance Management (the "Adviser" or "Eaton
                                 Vance"), a wholly-owned subsidiary of Eaton
                                 Vance Corp., is the Trust's investment adviser
                                 and administrator. The Adviser was one of the
                                 first investment advisers to manage a portfolio
                                 of Senior Loans in a publicly offered
                                 investment company, and has done so
                                 continuously since 1989. Eaton Vance currently
                                 sponsors Eaton Vance Prime Rate Reserves, a
                                 closed-end investment company that commenced
                                 investment operations in August, 1989, and EV
                                 Classic Senior Floating-Rate Fund, a closed-end
                                 fund that commenced investment operations in
                                 February, 1995. Each of these funds, as well as
                                 an offshore fund offered to non-U.S. investors,
                                 invests substantially all of its respective
                                 assets in the Senior Debt Portfolio (the
                                 "Portfolio"), a registered investment company
                                 that serves as the vehicle through which such
                                 funds invest in a common portfolio of Senior
                                 Loans. The Portfolio is co-managed by the same
                                 portfolio managers employed by the Adviser who
                                 will co-manage the Trust's assets. For the
                                 three-year and five-year periods ended
                                 September 30, 1998 with respect to Eaton Vance
                                 Prime Rate Reserves, and for the three-year
                                 period ended September 30, 1998 with respect to
                                 the EV Classic Senior Floating-Rate Fund, each
                                 such fund was awarded five stars by
                                 Morningstar, Inc. Morningstar is an independent
                                 evaluator of public investment companies and
                                 publishes proprietary ratings reflecting
                                 historical risk-adjusted performance.
                                 Morningstar ratings are calculated from a
                                 fund's annual returns in excess of the 90-day
                                 U.S. Treasury bill returns, with appropriate
                                 fee adjustments, and are further adjusted with
                                 a risk factor that reflects fund performance
                                 below 90-day Treasury bill returns. Eaton Vance
                                 Prime Rate Reserves and EV Classic Senior
                                 Floating-Rate Fund are in the Morningstar
                                 Taxable Bond Fund category, which includes
                                 1,491 (for such three year period) and 940 (for
                                 such five year period) other investment
                                 companies. A fund receives five stars if its
                                 risk-adjusted performance is in the top 10% of
                                 its rating category. Certain investment
                                 policies and restrictions of Eaton Vance Prime
                                 Rate Reserves and the EV Classic Senior
                                 Floating-Rate Fund differ from those of the
                                 Trust. The portfolio holdings and investment
                                 performance of such funds are expected to
                                 differ from those of the Trust. Past
                                 performance of such funds is not indicative of
                                 the Trust's performance. See "Management of the
                                 Trust."


SHAREHOLDER SERVICING AGENT...   PaineWebber Incorporated has been retained by
                                 the Administrator to act as the Shareholder
                                 Servicing Agent of the Trust. See "Shareholder
                                 Servicing Agent, Custodian and Transfer Agent."

DISTRIBUTIONS.................   The Trust's policy will be to make monthly
                                 distributions to Shareholders of substantially
                                 all net investment income of the Trust.
                                 Distributions to Shareholders cannot be
                                 assured, and the amount of each monthly
                                 distribution will vary. The initial
                                 distribution to

                                        3

                                 Shareholders is expected to be paid
                                 approximately 60 days after the completion of
                                 this offering. See "Distributions and Taxes,"
                                 "Dividend Reinvestment Plan" and "Use of
                                 Proceeds."


DIVIDEND REINVESTMENT PLAN....   The Trust has established a Dividend
                                 Reinvestment Plan (the "Plan"). Under the Plan,
                                 all dividend and capital gain distributions
                                 will be automatically reinvested in additional
                                 Shares either purchased in the open market, or
                                 newly issued by the Trust if the Shares are
                                 trading at or above their net asset value, in
                                 either case unless a Shareholder elects to
                                 receive cash. Shareholders who intend to hold
                                 their 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 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 objective 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,
                                 including investments in illiquid securities
                                 such as Senior Loans. However, shares of
                                 closed-end funds frequently trade at a discount
                                 from their net asset value. In recognition of
                                 the possibility that the Shares might trade at
                                 a discount to net asset value and that any such
                                 discount may not be in the interest of
                                 Shareholders, the Trust's Board of Trustees
                                 (the "Board"), in consultation with Eaton
                                 Vance, from time to time may review possible
                                 actions to reduce any such discount. The Board
                                 might consider open market repurchases or
                                 tender offers for Shares at net asset value.
                                 There can be no assurance that the Board will
                                 decide to undertake any of these actions or
                                 that, if undertaken, such actions would result
                                 in the Shares trading at a price equal to or
                                 close to net asset value per Share. The Board
                                 might also consider the conversion of the Trust
                                 to an open-end mutual fund. The Board of
                                 Trustees believes, however, that the closed-end
                                 structure is desirable, given the Trust's
                                 investment objective and policies. Investors
                                 should assume, therefore, that it is highly
                                 unlikely that the Board would vote to convert
                                 the Trust to an open-end investment company.

See "Description of Capital Structure."

SPECIAL RISK CONSIDERATIONS...   No Operating History.  The Trust is a
                                 closed-end investment company with no history
                                 of operations and is designed for long-term
                                 investors and not as a trading vehicle.

                                 Trust will invest may not be rated by a
                                 nationally recognized statistical rating
                                 organization, will not be registered with the
                                 SEC or any state securities commission and
                                 generally will not be listed on any

4

national securities exchange. Therefore, the amount of public information available about Senior Loans will be limited, and the performance of the Trust is more dependent on the analytical abilities of the Adviser than would be the case for an investment company that invests primarily in more widely rated, registered or exchange-listed securities. In evaluating the creditworthiness of Borrowers, the Adviser will consider, and may rely in part, on analyses performed by others. Moreover, because Senior Loans are subject to contractual restrictions on resale they are illiquid, which may impair the Trust's ability to realize the full value of its assets in the event of a voluntary or involuntary liquidation of such assets.

Credit Risk. Senior Loans, like other debt obligations, are subject to the risk of non-payment of scheduled interest or principal. Such non-payment would result in a reduction of income to the Trust, a reduction in the value of the Senior Loan experiencing non-payment and a potential decrease in the net asset value of the Trust. Although Senior Loans in which the Trust will invest will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the Borrower's obligation in the event of default or that such collateral could be readily liquidated. Senior Loans and the other debt securities in which the Trust may invest typically will be below investment grade quality. Such investments generally have speculative characteristics, and companies obligated by such debt are generally more vulnerable in an economic downturn. In the event of bankruptcy of a Borrower, the Trust could experience delays or limitations in its ability to realize the benefits of any collateral securing a Senior Loan. In addition, the Trust may purchase interests in Senior Loans from financial intermediaries whereby the Trust depends on the intermediary for payment of principal and interest on the Senior Loan. A decline in the financial soundness of such intermediaries may, therefore, adversely affect the Trust. See "Investment Objective, Policies and Risks."

Interest Rate Fluctuations. When interest rates decline, the value of a portfolio invested in fixed-rate obligations can be expected to rise. Conversely, when interest rates rise, the value of a portfolio invested in fixed-rate obligations can be expected to decline. Although the Trust's net asset value will vary, the Trust's management expects the Trust's policy of acquiring primarily interests in floating rate Senior Loans to minimize fluctuations in net asset value resulting from changes in market interest rates. However, because floating or variable rates on Senior Loans only reset periodically, changes in prevailing interest rates can be expected to cause some fluctuation in the Trust's net asset value. Similarly, a sudden and significant increase in market interest rates, may cause a decline in the Trust's net asset value. Moreover, as much as 10% of the total assets of the Trust may be invested in income securities with fixed rates of interest, which may lose value in direct response to market interest rate increases.

Effects of Leverage. The use of leverage by the Trust creates an opportunity for increased net income, but, at the same time,

5

creates special risks. There can be no assurance that a leveraging strategy will be successful during any period in which it is employed. The Trust intends to utilize leverage to provide the holders of Shares with a potentially higher return. Leverage creates risks for holders of Shares, including the likelihood of greater volatility of net asset value and market price of the Shares and the risk that fluctuations in interest rates on borrowings and debt or in the dividend rates on any preferred shares may affect the return to Shareholders. To the extent the income derived from securities purchased with funds received from leverage exceeds the cost of leverage, the Trust's return will be greater than if leverage had not been used. Conversely, if the income from the securities purchased with such funds is not sufficient to cover the cost of leverage, the return to the Trust will be less than if leverage had not been used, and therefore the amount available for distribution to Shareholders as dividends and other distributions will be reduced. In the latter case, Eaton Vance in its best judgment may nevertheless determine to maintain the Trust's leveraged position if it deems such action to be appropriate in the circumstances. As discussed under "Management of the Trust," the fee paid to Eaton Vance will be calculated on the basis of the Trust's total assets, including proceeds from borrowings for leverage and the issuance of preferred shares, so the fees will be higher when leverage is utilized. Certain types of borrowings by the Trust may result in the Trust being subject to covenants in credit agreements, including those relating to asset coverage and portfolio composition requirements. The Trust may be subject to certain restrictions on investments imposed by guidelines of one or more rating agencies, which may issue ratings for the debt securities or preferred shares issued by the Trust. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Trust by the Investment Company Act of 1940, as amended (the "Investment Company Act" or "1940 Act"). It is not anticipated that these covenants or guidelines will impede Eaton Vance in managing the Trust's portfolio in accordance with its investment objective and policies. See "Investment Objective, Policies and Risks -- Use of Leverage and Related Risks."

Special Investment Practices. The Trust may use various investment practices that involve special considerations including lending its portfolio securities and entering into repurchase and reverse repurchase agreements. In addition, the Trust has the authority to engage in interest rate and other hedging and risk management transactions. For a discussion of these practices, see "Investment Objective, Policies and Risks -- Special Investment Practices."

Investment in Non-U.S. Issuers. The Trust may invest in Senior Loans and other income producing securities of issuers that are organized or located in countries other than the United States, provided that such investments are denominated in U.S. dollars and provide for the payment of interest and repayment of principal in U.S. dollars. An investment in non-U.S. issuers involves special risks, including that non-U.S. issuers may be subject to less rigorous accounting and reporting requirements than U.S. issuers,

6

less rigorous regulatory requirements, differing legal systems and laws relating to creditors' rights, the potential inability to enforce legal judgments and the potential for political, social and economic adversity.

Market Price of Shares. The shares of closed-end investment companies often trade at a discount from their net asset value, and the Trust's Shares may likewise trade at a discount from net asset value. The trading price of the Trust's Shares may be less than the public offering price. This risk may be greater for investors who sell their Shares in a relatively short period after completion of the public offering.

Non-Diversification. The Trust has registered as a "non-diversified" investment company under the 1940 Act. Under federal income tax rules applicable to the Trust, with respect to 50% of its assets, it will be able to invest more than 5% of the value of its assets in the obligations of any single issuer, although it has no current intention to do so. The Trust will not invest more than 10% of its assets in securities (including interests in Senior Loans) of any single Borrower. To the extent the Trust invests a relatively high percentage of its assets in obligations of a limited number of issuers, the Trust may be more susceptible than a more widely diversified investment company to any single corporate, economic, political or regulatory occurrence.

Anti-Takeover Provisions. The Trust's Declaration of Trust includes provisions that could have the effect of limiting the ability of other persons or entities to acquire control of the Trust or to change the composition of its Board of Trustees. See "Description of Capital Structure -- Anti-Takeover Provisions in the Declaration of Trust."

THE TRUST

Eaton Vance Senior Income Trust (the "Trust") is a newly organized, non-diversified, closed-end management investment company which was organized as a Massachusetts business trust on September 23, 1998 and has no operating history. The Trust's principal office is located at 24 Federal Street, Boston, MA 02110 and its telephone number is 1-800-225-6265.

This Prospectus relates to the initial public offering of the Trust's shares of beneficial interest, $.01 par value (the "Shares"). The Shares will be sold during the initial public offering without any sales load or underwriting discounts payable by investors or the Trust. Eaton Vance Management (the "Adviser" or "Eaton Vance") or an affiliate (not the Trust) from its own assets will pay a commission to the Underwriters in connection with sales of the Shares in this offering. See "Underwriting."

USE OF PROCEEDS

The proceeds of this offering, before deduction of offering expenses, estimated to be $ (or $ assuming exercise of the Underwriters' over-allotment option in full), will be invested in accordance with the Trust's investment objective 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. Eaton Vance has agreed to pay all offering expenses of the Trust that exceed $0.02 per Share.

INVESTMENT OBJECTIVE, POLICIES AND RISKS

INVESTMENT OBJECTIVE

The Trust's investment objective is to provide Shareholders with a high level of current income, consistent with preservation of capital, by investing primarily in senior secured floating rate loans ("Senior Loans"). Investment in such floating rate instruments is expected to minimize changes in the underlying principal value of the Senior Loans, and therefore the Trust's net asset value, resulting from changes in market interest rates. The borrowers of such loans will be corporations, partnerships and other business entities ("Borrowers") which operate in a variety of industries and geographical regions. The Trust provides individual investors with access to a market normally accessible only to financial institutions and larger corporate or institutional investors.

INVESTMENT POLICIES -- GENERAL COMPOSITION OF THE TRUST

In normal market conditions, at least 80% of the Trust's total assets will be invested in interests in Senior Loans (either as an original Lender or as a purchaser of an Assignment or Participation, each as defined below) of domestic or foreign Borrowers (so long as foreign loans are U.S. dollar-denominated and payments of interest and repayments of principal are required to be made in U.S. dollars). The Trust may invest up to 20% of its total assets in (i) loan interests which are not secured by any, or that have a lower than senior claim on, collateral, (ii) other income producing securities such as investment and non-investment grade corporate debt securities and U.S. government and U.S. dollar-denominated foreign government or supranational debt securities (subject to the limit that no more than 10% of the Trust's total assets may be invested in securities with a fixed rate of interest), and (iii) warrants and equity securities issued by a Borrower or its affiliates as part of a package of investments in the Borrower or its affiliates. If the Adviser determines that market conditions temporarily warrant a defensive investment policy, the Trust may invest up to 100% of its assets in cash and high quality, short-term debt securities.

Based upon available market data, the Adviser believes that the overall market for U.S. debt securities, including U.S. government securities, investment and non-investment grade corporate bonds, mortgage-related securities and commercial paper, totaled an outstanding principal amount of approximately $8.4 trillion at the end of 1997, and that Senior Loans represented approximately $375 billion (or 4.5%) of that total amount. Senior Loans in which the Trust will invest generally pay interest at rates which are redetermined periodically by reference to a base lending rate, plus a premium. These base lending rates generally are the prime rate offered by one or more major United States banks (the "Prime Rate"), the London Inter-Bank

9

Offered Rate ("LIBOR"), the certificate of deposit ("CD") rate or other base lending rates used by commercial lenders. The following table is intended to provide investors with a comparison of short-term money market rates, a representative base commercial lending rate, and a representative indicator of the premium over such base lending rate for Senior Loans. The representative indicator shown below is derived from the DLJ Leveraged Loan Index, which was designed in January 1992 to mirror the investible universe of the market for Senior Loans. The DLJ Leveraged Loan Index includes approximately $58 billion of Senior Loans and new Senior Loan issues are added when they meet certain criteria. The DLJ Leveraged Loan Index is an unmanaged index and, although the Adviser believes that the spreads over LIBOR reported in connection with the determination of the Index (which are an average of the contractual spreads set forth in the loan agreements relating to the Senior Loans included in the Index) are representative of the historical average spreads in the overall market for Senior Loans, the Trust will have no direct investment in, nor will its performance be indicative of, this Index. The following comparison should not be considered a representation of future money market rates, spreads of Senior Loans over base reference rates nor what an investment in the Trust may earn or what an investor's yield or total return may be in the future.

It is anticipated that the proceeds of the Senior Loans in which the Trust will acquire interests primarily will be used to finance leveraged buyouts, recapitalizations, mergers, acquisitions, stock repurchases, and, to a lesser extent, to finance internal growth and for other corporate purposes of Borrowers. Senior Loans have the most senior position in a Borrower's capital structure, although some Senior Loans may hold an equal ranking with other senior securities of the Borrower. The capital structure of a Borrower may include Senior Loans, senior and junior subordinated debt, preferred stock and common stock issued by the Borrower, typically in descending order of seniority with respect to claims on the Borrower's assets (described below). Senior Loans are secured by specific collateral.

In order to borrow money pursuant to a Senior Loan, a Borrower will frequently, for the term of the Senior Loan, pledge collateral, including but not limited to, (i) working capital assets, such as accounts receivable and inventory; (ii) tangible fixed assets, such as real property, buildings and equipment; (iii) intangible assets, such as trademarks and patent rights (but excluding goodwill); and (iv) security interests in shares of stock of subsidiaries or affiliates. In the case of Senior Loans made to non-public companies, the company's shareholders or owners may provide collateral in the form of secured guarantees and/or security interests in assets that they own. In certain instances, a Senior Loan may be secured only by stock in the Borrower or its subsidiaries. Collateral may consist of assets that may not be readily liquidated, and there is no assurance that the liquidation of such assets would satisfy fully a Borrower's obligations under a Senior Loan. The Trust will not invest in a Senior Loan unless, at the time of investment, the Adviser determines that the value of the collateral equals or exceeds the aggregate outstanding principal amount of the Senior Loan.

10

The Trust is not subject to any restrictions with respect to the maturity of Senior Loans held in its portfolio. Senior Loans typically have a stated term of between five and nine years, and have rates of interest which typically are redetermined either daily, monthly, quarterly or semi-annually. Longer interest rate reset periods generally increase fluctuations in the Trust's net asset value as a result of changes in market interest rates. The Senior Loans in the Trust's portfolio will have a dollar-weighted average period until the next interest rate adjustment of approximately 90 days or less. As a result, as short-term interest rates increase, interest payable to the Trust from its investments in Senior Loans should increase, and as short-term interest rates decrease, interest payable to the Trust from its investments in Senior Loans should decrease. The Trust may utilize certain investment practices to, among other things, shorten the effective interest rate redetermination period of Senior Loans in its portfolio. In the experience of the Adviser over the last decade, because of prepayments the average life of Senior Loans has been two to three years.

A lender may have certain obligations pursuant to a loan agreement relating to Senior Loans, which may include the obligation to make additional loans in certain circumstances. The Trust generally will reserve against such contingent obligations by segregating a sufficient amount of cash, liquid securities and liquid Senior Loans, subject to the Trust's borrowing limitations. The Trust will not purchase interests in Senior Loans that would require the Trust to make any such additional loans if such additional loan commitments in the aggregate would exceed 20% of the Trust's total assets or would cause the Trust to fail to meet its tax diversification requirements.

The Trust may purchase and retain in its portfolio a Senior Loan where the Borrower has experienced, or may be perceived to be likely to experience, credit problems, including involvement in or recent emergence from bankruptcy reorganization proceedings or other forms of debt restructuring. Such investments may provide opportunities for enhanced income as well as capital appreciation. At times, in connection with the restructuring of a Senior Loan either outside of bankruptcy court or in the context of bankruptcy court proceedings, the Trust may determine or be required to accept equity securities or junior debt securities in exchange for all or a portion of a Senior Loan.

The Trust also may invest up to 5% of its total assets in structured notes with rates of return determined by reference to the total rate of return on one or more Senior Loans referenced in such notes. The rate of return on the structured note may be determined by applying a multiplier to the rate of total return on the referenced Senior Loan or Loans. Application of a multiplier is comparable to the use of financial leverage, a speculative technique. Leverage magnifies the potential for gain and the risk of loss; as a result, a relatively small decline in the value of a referenced note could result in a relatively large loss in the value of a structured note. See "Use of Leverage and Related Risks" below. Structured notes will be treated as Senior Loans for purposes of the Trust's policy of normally investing at least 80% of its assets in Senior Loans, and may be subject to the Trust's leverage limitations.

The Trust has adopted certain fundamental investment restrictions set forth in the Statement of Additional Information which may not be changed without a Shareholder vote. Except for such restrictions, the investment objective and policies of the Trust may be changed by the Board of Trustees without Shareholder action.

CERTAIN CHARACTERISTICS OF SENIOR LOANS

A Senior Loan is typically originated, negotiated and structured by a U.S. or foreign commercial bank, insurance company, finance company or other financial institution (the "Agent") for a lending syndicate of financial institutions ("Lenders"). The Agent typically administers and enforces the Senior Loan on behalf of the other Lenders in the syndicate. In addition, an institution, typically but not always the Agent, holds any collateral on behalf of the Lenders.

Senior Loans include senior secured floating rate loans and institutionally traded senior secured floating rate debt obligations issued by an asset-backed pool, and interests therein. Loan interests generally take the form of direct interests acquired during a primary distribution and may also take the form of participation interests in, assignments of, or novations of a Senior Loan acquired in secondary markets. Such loan interests may be acquired from U.S. or foreign commercial banks, insurance companies, finance companies or other

11

financial institutions who have made loans or are members of a lending syndicate or from other holders of loan interests.

The Trust may purchase "Assignments" from Lenders. The purchaser of an Assignment typically succeeds to all the rights and obligations under the Loan Agreement of the assigning Lender and becomes a Lender under the Loan Agreement with the same rights and obligations as the assigning Lender. Assignments may, however, be arranged through private negotiations between potential assignees and potential assignors, and the rights and obligations acquired by the purchaser of an Assignment may differ from, and be more limited than, those held by the assigning Lender.

The Trust also may invest without limit in "Participations." Participations by the Trust in a Lender's portion of a Senior Loan typically will result in the Trust having a contractual relationship only with such Lender, not with the Borrower. As a result, the Trust may have the right to receive payments of principal, interest and any fees to which it is entitled only from the Lender selling the Participation and only upon receipt by such Lender of such payments from the Borrower. In connection with purchasing Participations, the Trust generally will have no right to enforce compliance by the Borrower with the terms of the loan agreement, nor any rights with respect to any funds acquired by other Lenders through set-off against the Borrower and the Trust may not directly benefit from the collateral supporting the Senior Loan in which it has purchased the Participation. As a result, the Trust may assume the credit risk of both the Borrower and the Lender selling the Participation. In the event of the insolvency of the Lender selling a Participation, the Trust may be treated as a general creditor of such Lender. The selling Lenders and other persons interpositioned between such Lenders and the Trust with respect to such Participations will likely conduct their principal business activities in the banking, finance and financial services industries. Persons engaged in such industries may be more susceptible to, among other things, fluctuations in interest rates, changes in the Federal Open Market Committee's monetary policy, governmental regulations concerning such industries and concerning capital raising activities generally and fluctuations in the financial markets generally.

The Trust will only acquire Participations if the Lender selling the Participation, and any other persons interpositioned between the Trust and the Lender, at the time of investment has outstanding debt or deposit obligations rated investment grade (BBB or A-3 or higher by Standard & Poor's Ratings Group
("S&P") or Baa or P-3 or higher by Moody's Investors Service, Inc. ("Moody's")
or comparably rated by another nationally recognized rating agency (each a "Rating Agency")) or determined by the Adviser to be of comparable quality. Similarly, the Trust will purchase an Assignment or Participation or act as a Lender with respect to a syndicated Senior Loan only where the Agent with respect to such Senior Loan at the time of investment has outstanding debt or deposit obligations rated investment grade or determined by the Adviser to be of comparable quality. Long-term debt rated BBB by S&P is regarded by S&P as having adequate capacity to pay interest and repay principal and debt rated Baa by Moody's is regarded by Moody's as a medium grade obligation, i.e., it is neither highly protected nor poorly secured. Commercial paper rated A-3 by S&P indicates that S&P believes such obligations exhibit adequate protection parameters but that adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation and issues of commercial paper rated P-3 by Moody's are considered by Moody's to have an acceptable ability for repayment of short-term debt obligations but the effect of industry characteristics and market compositions may be more pronounced. A description of the corporate bond ratings of Moody's and S&P is included as Appendix A to the Statement of Additional Information.

12

OTHER INCOME PRODUCING SECURITIES

The Trust, with respect to 20% of its total assets, may purchase a variety of U.S. and foreign corporate and government debt obligations that are U.S. dollar-denominated. The Adviser may consider capital appreciation potential when investing in such income producing debt securities, which may have fixed, variable or floating rates of interest. These securities may include (i) interests in loans from Borrowers that are not secured by any, or that have lower than senior claim on, collateral, (ii) other income producing securities such as investment and non-investment grade corporate debt securities and U.S. government and U.S. dollar-denominated foreign government or supranational debt securities (subject to the limit that no more than 10% of the Trust's total assets may be invested in securities with a fixed rate of interest), and (iii) warrants and equity securities issued by a Borrower or its affiliates as part of a package of investments in the Borrower or its affiliates.

USE OF LEVERAGE AND RELATED RISKS

The Trust expects to utilize leverage through borrowings, including the issuance of debt securities, or the issuance of preferred shares or through other transactions, such as reverse repurchase agreements, which have the effect of financial leverage. The Trust intends to utilize leverage in an amount up to approximately 33 1/3% of its total assets (including the amount obtained from leverage). The Trust generally will not utilize leverage if the Adviser anticipates that it would result in a lower return to Shareholders for any significant amount of time. The Trust also 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 Trust securities.

Leverage creates risks for holders of the Shares, including the likelihood of greater volatility of net asset value and market price of the Shares. Although there is a risk that fluctuations in interest rates on borrowings and short-term debt or in the dividend rates on any preferred shares may adversely affect the return to the holders of the Shares, the Adviser believes that this should be mitigated when the Trust uses leverage with floating rate costs, because the Trust's costs of leverage and its portfolio of Senior Loans will ordinarily have similar floating rates of interest. If the income from the securities purchased with such funds is not sufficient to cover the cost of leverage, the return on the Trust will be less than if leverage had not been used, and therefore the amount available for distribution to Shareholders as dividends and other distributions will be reduced. The Adviser in its best judgment nevertheless may determine to maintain the Trust's leveraged position if it deems such action to be appropriate in the circumstances. As discussed under "Management of the Trust," during periods in which the Trust is utilizing leverage the fees paid to Eaton Vance for investment advisory and administrative services will be higher than if the Trust did not utilize leverage because the fees paid will be calculated on the basis of the Trust's total assets, including proceeds from borrowings for leverage and the issuance of preferred shares.

Capital raised through leverage will be subject to interest costs or dividend payments which may exceed the income and appreciation on the assets purchased. The Trust also may be required to maintain, among other things, minimum average balances in connection with borrowings or to pay a commitment or other fee to maintain a line of credit; any such requirements will increase the cost of borrowing over the stated interest rate. The issuance of preferred shares involves offering expenses and other costs and may limit the Trust's freedom to pay dividends on Shares or to engage in other activities. Borrowings and the issuance of a class of preferred shares having priority over the Trust's Shares create an opportunity for greater return per Share, but at the same time such leveraging is a speculative technique in that it will increase the Trust's exposure to capital risk. Unless the income and appreciation, if any, on assets acquired with borrowed funds or offering proceeds exceed the cost of borrowing or issuing additional classes of securities (and other Trust expenses), the use of leverage will diminish the investment performance of the Trust's Shares compared with what it would have been without leverage.

Certain types of borrowings may result in the Trust being subject to covenants in credit agreements, including those relating to asset coverage and portfolio composition requirements. The Trust may be subject to certain restrictions on investments imposed by guidelines of one or more Rating Agencies which may issue

13

ratings for any corporate debt securities or preferred shares issued by the Trust. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Trust by the Investment Company Act. It is not anticipated that these covenants or guidelines will impede the Adviser from managing the Trust's portfolio in accordance with the Trust's investment objective and policies. The Trust currently is in preliminary negotiations with commercial banks to arrange a credit facility. The terms of any agreements relating to the credit facility, including commitment and facility fees and the rate of interest charged on such borrowings, have not been determined and are subject to a definitive agreement and other conditions.

Under the Investment Company Act, the Trust is not permitted to incur indebtedness unless immediately after such incurrence the Trust has an asset coverage of at least 300% of the aggregate outstanding principal balance of indebtedness (i.e., such indebtedness may not exceed 33 1/3% of the Trust's total assets). Additionally, under the Investment Company Act, the Trust may not declare any dividend or other distribution upon any class of its capital shares (including the Shares), or purchase any such capital shares, unless the aggregate indebtedness of the Trust has, at the time of the declaration of any such dividend or distribution or at the time of any such purchase, an asset coverage of at least 300% after deducting the amount of such dividend, distribution, or purchase price, as the case may be. Under the Investment Company Act, the Trust is not permitted to issue preferred shares unless immediately after such issuance the net asset value of the Trust's portfolio is at least 200% of the liquidation value of the outstanding preferred shares (i.e., such liquidation value may not exceed 50% of the Trust's total assets). In addition, the Trust is not permitted to declare any cash dividend or other distribution on its Shares unless, at the time of such declaration, the net asset value of the Trust's portfolio (determined after deducting the amount of such dividend or other distribution) is at least 200% of such liquidation value. If preferred shares are issued, the Trust intends, to the extent possible, to purchase or redeem preferred shares from time to time to maintain coverage of any preferred shares of at least 200%.

The Trust's willingness to borrow money and issue new securities for investment purposes, and the amount the Trust will borrow or issue, will depend on many factors, the most important of which are market conditions and interest rates. Successful use of a leveraging strategy depends on the Adviser's ability to predict correctly interest rates and market movements, and there is no assurance that a leveraging strategy will be successful during any period in which it is employed.

Assuming the utilization of leverage in the amount of approximately 33 1/3% of the Trust's total assets and an annual interest rate on borrowings of 6.10% payable on such leverage based on market rates as of the date of this Prospectus, the annual return that the total assets in the Trust's portfolio must experience (net of expenses) in order to cover such interest payments would be 2.03%. The Trust's actual cost of leverage will be based on market rates at the time the Trust undertakes a leveraging strategy, and such actual cost of leverage may be higher or lower than that assumed in the previous example.

The following table is designed to illustrate the effect on the return to a holder of the Trust's Shares of leverage in the amount of approximately 33 1/3% of the Trust's total assets, assuming hypothetical annual returns of the Trust's portfolio of minus 10% to plus 10%. As the table shows, leverage generally increases the return to Shareholders when portfolio return is positive and greater than the cost of leverage and decreases the return when the portfolio return is negative or less than the cost of leverage. The figures appearing in the table are hypothetical and actual returns may be greater or less than those appearing in the table.

Assuming Portfolio Return (net of expenses).......     (10)%      (5)%      0%      5%      10%
Corresponding Share Return Assuming 33 1/3%
  Leverage........................................  (18.05)%  (10.55)%  (3.05)%  4.45%   11.95%

Until the Trust borrows or issues preferred shares, the Shares will not be leveraged, and the risks and special considerations related to leverage described in this Prospectus will not apply. Such leveraging of the Shares cannot be achieved until the proceeds resulting from the use of leverage have been invested in accordance with the Trust's investment objective and policies.

ADDITIONAL RISK CONSIDERATIONS

Interest Rate Risk. When interest rates decline, the value of a portfolio invested in fixed-rate obligations can be expected to rise. Conversely, when interest rates rise, the value of a portfolio invested in fixed-rate obligations can be expected to decline. Although the Trust's net asset value will vary, the Trust's management expects the Trust's policy of acquiring primarily interests in floating rate Senior Loans to minimize fluctuations in net asset value as a result of changes in market interest rates. However, because floating rates on Senior Loans only reset periodically, changes in prevailing interest rates can be expected to cause some fluctuation in the Trust's net asset value. Similarly, a sudden and significant increase in market interest rates may cause a decline in the Trust's net asset value. Moreover, as much as 10% of the total assets of the Trust may be invested in income securities with fixed rates of interest, which may lose value in direct response to market interest rate increases.

Credit Risk. Senior Loans, like other corporate debt obligations, are subject to the risk of non-payment of scheduled interest or principal. Such non-payment would result in a reduction of income to the Trust, a reduction in the value of the Senior Loan experiencing non-payment and a potential decrease in the net asset value of the Trust. Although, with respect to Senior Loans, the Trust generally will invest only in Senior Loans that the Adviser believes are secured by specific collateral the value of which equals or exceeds the principal amount of the Senior Loan at the time of initial investment, there can be no assurance that the liquidation of any such collateral would satisfy the Borrower's obligation in the event of non-payment of scheduled interest or principal payments, or that such collateral could be readily liquidated. In the event of bankruptcy of a Borrower, the Trust could experience delays or limitations with respect to its ability to realize the benefits of the collateral securing a Senior Loan. To the extent that a Senior Loan is collateralized by stock in the Borrower or its subsidiaries, such stock may lose all or substantially all of its value in the event of bankruptcy of the Borrower. The Agent generally is responsible for determining that the Lenders have obtained a perfected security interest in the collateral securing the Senior Loan. Some Senior Loans in which the Trust may invest are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate such Senior Loans to presently existing or future indebtedness of the Borrower or take other action detrimental to the holders of Senior Loans, such as the Trust, including, in certain circumstances, invalidating such Senior Loans.

Senior Loans in which the Trust will invest often are not rated by a Rating Agency, will not be registered with the SEC or any state securities commission and will not be listed on any national securities exchange. Although the Trust will have access to financial and other information made available to the Lenders in connection with Senior Loans, the amount of public information available with respect to Senior Loans will generally be less extensive than that available for rated, registered or exchange listed securities. Borrowers may have outstanding debt obligations that are rated below investment grade by a Rating Agency. More recently, such Rating Agencies have begun rating Senior Loans and many Senior Loans have been assigned a rating below investment grade. The Trust will invest in such Senior Loans. Debt securities which are unsecured and rated below investment grade are viewed by the Rating Agencies as having speculative characteristics and are commonly known as "junk bonds." A description of the ratings of corporate bonds by Moody's and S&P is included as Appendix A to the Statement of Additional Information. Because of the protective features of Senior Loans (being senior and secured by specific collateral), the Adviser believes, based on its experience, that these ratings do not necessarily reflect the true risk of loss of principal or interest on a Senior Loan. For example, the Adviser believes that Senior Loans tend to have more favorable loss recovery rates as compared to most other types of below investment grade debt obligations. Accordingly, the Adviser generally does not take ratings into account when determining whether to invest in a Senior Loan and, in any event, does not view ratings as a determinative factor in its investment decisions. Investing in Senior Loans does, however, involve investment risk, and some Borrowers default on their Senior Loan payments. The Trust attempts to manage these risks through portfolio diversification and careful analysis and monitoring of Borrowers. As a result, the Trust is more dependent on the Adviser's credit analysis abilities than a fund that invests in other types of debt securities.

15

The Trust may invest up to 20% of its total assets in: Loans from Borrowers that are not secured by any, or that have lower than a senior claim on, collateral; in warrants and equity securities acquired in connection with the Trust's ownership of Senior Loans; and in other income producing securities such as investment grade and below investment grade corporate debt securities and U.S. government and U.S. dollar-denominated foreign government or supranational debt securities (subject to the limit that no more than 10% of the Trust's total assets may be invested in securities with a fixed rate of interest). Securities rated below investment grade are commonly referred to as "junk bonds."

Securities rated below investment grade or unrated securities of comparable quality ("lower quality securities") are subject to the risk of an issuer's inability to meet principal and interest payments on the obligations (credit risk) and may also be subject to price volatility due to such factors as interest rate sensitivity, market perception of the creditworthiness of the issuer and general market liquidity (market risk). The prices of lower quality securities are also more likely to react to real or perceived developments affecting market and credit risk than are prices of investment grade quality securities ("high quality securities"), which react primarily to movements in the general level of interest rates. A substantial portion of the Trust's portfolio of Senior Loans and other debt securities may be lower quality securities issued in connection with mergers, acquisitions, leveraged buy-outs, recapitalizations and other highly leveraged transactions, which pose a higher risk of default or bankruptcy of the issuer than other higher quality debt securities, particularly during periods of deteriorating economic conditions and contraction in the credit markets. The investments in the Trust's portfolio will have speculative characteristics.

Foreign Securities. Although the Trust will only invest in U.S. dollar-denominated income securities, the Trust may invest in Senior Loans and other debt securities of non-U.S. issuers. Investment in securities of non-U.S. issuers involves special risks, including that non-U.S. issuers may be subject to less rigorous accounting and reporting requirements than U.S. issuers, less rigorous regulatory requirements, differing legal systems and laws relating to creditors' rights, the potential inability to enforce legal judgments and the potential for political, social and economic adversity. The willingness and ability of sovereign issuers to pay principal and interest on government securities depends on various economic factors, including among others the issuer's balance of payments, overall debt level, and cash flow considerations related to the availability of tax or other revenues to satisfy the issuer's obligations. Supranational organizations do not have taxing powers, so they are dependent upon their members' continued support in order to meet interest and principal payments. The securities of some foreign issuers are less liquid and at times more volatile than securities of comparable U.S. issuers. Foreign settlement procedures and trade regulations may involve certain risks (such as delay in the payment or delivery of securities and interest or in the recovery of assets held abroad) and expenses not present in the settlement of domestic investments. Investments may include securities issued by the governments of lesser-developed countries, which are sometimes referred to as "emerging markets." There may be a possibility of nationalization or expropriation of assets, imposition of currency exchange controls, confiscatory taxation, political or financial instability, armed conflict and diplomatic developments which could affect the value of the Trust's investments in certain foreign countries.

Liquidity Risk. Senior Loans, at present, are generally not readily marketable and are subject to restrictions on resale. Interests in Senior Loans generally are not listed on any national securities exchange or automated quotation system and no active trading market may exist for many of the Senior Loans in which the Trust will invest. Where a secondary market exists, such market may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Senior Loans are thus relatively illiquid, which illiquidity may impair the Trust's ability to realize the full value of its assets in the event of a voluntary or involuntary liquidation of such assets. The Trust has no limitation on the amount of its assets which may be invested in securities which are not readily marketable or are subject to restrictions on resale. The substantial portion of the Trust's assets invested in Senior Loan interests may restrict the ability of the Trust to dispose of its investments in a timely fashion and at a fair price, and could result in capital losses to the Trust and holders of Shares. The risks associated with illiquidity are particularly acute in situations where the Trust's operations require cash, such as if the Trust tenders for its Shares, and may result in the Trust borrowing to meet short-term cash requirements.

16

Regulatory Changes. To the extent that legislation or state or federal regulators that regulate certain financial institutions impose additional requirements or restrictions with respect to the ability of such institutions to make loans, particularly in connection with highly leveraged transactions, the availability of Senior Loans for investment by the Trust may be adversely affected. Further, such legislation or regulation could depress the market value of Senior Loans held by the Trust.

Closed-End Funds. The Trust is a closed-end investment company with no history of operations and is designed primarily for long-term investors and not as a trading vehicle. The shares of closed-end investment companies often trade at a discount from their net asset value, and the Trust's Shares may likewise trade at a discount from net asset value. The trading price of the Trust's Shares may be less than the initial public offering price, creating a risk of loss for investors purchasing in the initial public offering of the Shares. This market price risk may be greater for investors who sell their Shares within a relatively short period after completion of this offering.

Non-Diversification. The Trust has registered as a "non-diversified" investment company under the 1940 Act so that, subject to its investment restrictions and in connection with federal income tax rules applicable to the Trust, with respect to 50% of its total assets, it will be able to invest more than 5% of the value of its assets in the obligations of any single issuer, including Senior Loans of a single Borrower or single Lender, although it has no current intention to do so. The Trust will not invest more than 10% of the value of its assets in securities (including interests in Senior Loans) of any single Borrower. Moreover, the Trust may invest more than 10% (but not more than 25%) of its total assets in Senior Loan interests for which the same intermediate participant is interposed between the Trust and the Borrower. To the extent the Trust invests a relatively high percentage of its assets in obligations of a limited number of issuers, the Trust will be more susceptible than a more widely diversified investment company to any single corporate, economic, political or regulatory occurrence.

Year 2000 Compliance. The Trust could be adversely affected if the computer systems used by the Adviser and other service providers do not properly process and calculate date-related information and data from and after January 1, 2000. This is commonly known as the "Year 2000 Problem." Eaton Vance is taking steps that it believes are reasonably designed to address the Year 2000 Problem with respect to computer systems that it uses and to obtain reasonable assurances that comparable steps are being taken by the Trust's other major service providers. At this time, there can be no assurance that these steps will be sufficient to avoid any adverse impact to the Trust.

In addition, it is possible that the markets for Senior Loans and other securities in which the Trust invests may be detrimentally affected by computer failures throughout the financial services industry beginning on or before January 1, 2000. Improperly functioning trading systems may result in settlement problems and liquidity issues. In addition, corporate and governmental data processing errors may result in production problems for individual companies and overall economic uncertainties. Earnings of individual issuers will be affected by remediation costs, which may be substantial and may be reported inconsistently in U.S. and foreign financial statements. Accordingly, the Trust's investments may be adversely affected.

SPECIAL INVESTMENT PRACTICES

The Trust may engage in the following investment practices to seek to enhance income or reduce investment risk, but has no current intention to do so.

Interest Rate and Other Hedging Transactions. The Trust may purchase or sell derivative instruments (which are instruments that derive their value from another instrument, security or index) to seek to hedge against fluctuations in securities prices or interest rates. The Trust's transactions in derivative instruments may include the purchase or sale of futures contracts on securities, securities indices or other indices, other financial instruments; options on futures contracts; exchange-traded and over-the-counter options on securities or indices; index-linked securities; and interest rate swaps. The Trust's transactions in derivative instruments involve a risk of loss or depreciation due to: unanticipated adverse changes in securities prices, interest rates, 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

17

portfolio management constraints on securities subject to such transactions. The loss on derivative instruments (other than purchased options) may substantially exceed the Trust's initial investment in these instruments. In addition, the Trust may lose the entire premium paid for purchased options that expire before they can be profitably exercised by the Trust. Transaction costs will be incurred in opening and closing positions in derivative instruments. There can be no assurance that the Adviser's use of derivative instruments will be advantageous to the Trust.

The Trust may use interest rate swaps for risk management purposes and not as a speculative investment and would typically use interest rate swaps to shorten the average time to interest rate reset of the Trust. Interest rate swaps involve the exchange by the Trust with another party of their respective commitments to pay or receive interest, e.g., an exchange of fixed rate payments for floating rate payments. The use of interest rate swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The Adviser has had limited experience in the use of interest rate swaps but has utilized other types of hedging and risk management techniques. If the Adviser is incorrect in its forecasts of market values, interest rates and other applicable factors, the investment performance of the Trust would be less favorable than what it would have been if this investment technique were never used.

Securities Lending. The Trust may seek to increase its income by lending portfolio securities to broker-dealers or other institutional borrowers. During the existence of a loan, the Trust will continue to receive the equivalent of the interest paid by the issuer on the securities loaned and will also receive a fee, or all or a portion of the interest on investment of the collateral, if any. However, the Trust may pay lending fees to such 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. However, the loans will be made only to organizations deemed by the Trust's Adviser to be of good standing and when, in the judgment of the Adviser, the consideration which can be earned from securities loans of this type, net of administrative expenses and any finders or other fees, justifies the attendant risk. The financial condition of the borrower will be monitored by the Adviser on an ongoing basis. The value of the securities loaned will not exceed 30% of the Trust's total assets.

Repurchase Agreements. The Trust may enter into repurchase agreements with member banks of the Federal Reserve System or primary dealers in U.S. Government securities. Under a repurchase agreement, the Trust buys securities at one price and simultaneously promises to sell back those securities at a higher price. The Trust's repurchase agreements will provide that the value of the collateral underlying the repurchase agreement will always be at least equal to the repurchase price, including any accrued interest earned on the repurchase agreement, and will be marked to market daily. The repurchase date is usually within seven days of the original purchase date. In all cases, the Adviser must be satisfied with the creditworthiness of the other party to the agreement before entering into a repurchase agreement. In the event of the bankruptcy of the other party to a repurchase agreement, the Trust might experience delays in recovering its cash. To the extent that, in the meantime, the value of the securities the Trust purchased may have declined, the Trust could experience a loss.

Reverse Repurchase Agreements. The Trust may also enter into "reverse" repurchase agreements which involve the sale of securities held and an agreement to repurchase the securities at an agreed-upon price, date, and interest payment. Reverse repurchase agreements involve risks similar to those described above under "-- Use of Leverage" and expose the Trust to the credit risk of the counterparty.

MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES

The management of the Trust, including general supervision of the duties performed by the Adviser under the Advisory Agreement, is the responsibility of the Trust's Board of Trustees under the laws of The Commonwealth of Massachusetts.

18

THE ADVISER

Eaton Vance Management acts as the Trust's investment adviser under an Investment Advisory Agreement ("Advisory Agreement"). The Adviser's principal office is located at 24 Federal Street, Boston, MA 02110. Eaton Vance, its affiliates and predecessor companies have been managing assets of individuals and institutions since 1924 and of investment companies since 1931. Eaton Vance (or its affiliates) currently serves as the investment adviser to investment companies and various individual and institutional clients with combined assets under management of over $27 billion, of which approximately $25 billion is in investment companies. Eaton Vance is a 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.

Eaton Vance was one of the first investment advisers to manage a portfolio of Senior Loans in a publicly offered investment company and has done so continuously since 1989. Eaton Vance currently offers Eaton Vance Prime Rate Reserves, a closed-end investment company that commenced investment operations in August, 1989, and EV Classic Senior Floating-Rate Fund, a closed-end fund that commenced investment operations in February, 1995. Each of these funds, as well as an offshore fund offered to non-U.S. investors, invests substantially all of its respective assets in the Senior Debt Portfolio, a registered investment company that serves as the vehicle through which such funds invest in a common portfolio of Senior Loans. For the three-year and five-year periods ended September 30, 1998 with respect to Eaton Vance Prime Rate Reserves, and for the three-year period ended September 30, 1998 with respect to the EV Classic Senior Floating-Rate Fund, each such fund was awarded five stars by Morningstar, Inc. Morningstar is an independent evaluator of public investment companies and publishes proprietary ratings reflecting historical risk-adjusted performance. Morningstar ratings are calculated from a fund's annual returns in excess of the 90-day U.S. Treasury bill returns, with appropriate fee adjustments and are further adjusted with a risk factor that reflects fund performance below 90-day Treasury bill returns. Eaton Vance Prime Rate Reserves and the EV Classic Senior Floating-Rate Fund are in the Morningstar Taxable Bond Fund category, which includes 1,491 (for such three year period) and 940 (for such five year period) other investment companies. A fund receives five stars if its risk-adjusted performance is in the top 10% of its rating category. Although these funds have substantially similar investment objectives and policies as the Trust, certain investment policies and restrictions of Eaton Vance Prime Rate Reserves and the EV Classic Senior Floating Rate Fund differ from those of the Trust. For example, such funds have not employed financial leverage for investment purposes and such funds have not invested in lower quality bonds with fixed rates of interest. Moreover, such funds are continuously offered and conduct quarterly tender offers so they have not been fully invested at all times. The portfolio holdings and investment performance of such funds will differ from those of the Trust. Past performance of such funds is not indicative of the Trust's performance.

Under the general supervision of the Trust's Board of Trustees, the Adviser will carry out the investment and reinvestment of the assets of the Trust, will furnish continuously an investment program with respect to the Trust, will determine which securities should be purchased, sold or exchanged, and will implement such determinations. The Adviser will furnish to the Trust investment advice and office facilities, equipment and personnel for servicing the investments of the Trust. The Adviser will compensate all Trustees and officers of the Trust who are members of the Adviser's organization and who render investment services to the Trust, and will also compensate all other Adviser personnel who provide research and investment services to the Trust. In return for these services, facilities and payments, the Trust has agreed to pay the Adviser as compensation under the Advisory Agreement a fee in the amount of .85% of the average weekly gross assets of the Trust. Gross assets of the Trust shall be calculated by deducting accrued liabilities of the Trust not including the principal amount of any indebtedness constituting financial leverage. The Adviser has agreed to waive its investment advisory fee for the two-month period following the date of this Prospectus.

Scott H. Page and Payson F. Swaffield are co-portfolio managers of the Trust and are responsible for day-to-day management of the Trust's investments. Mr. Page has been an employee of Eaton Vance since 1989 and Mr. Swaffield has been an employee of Eaton Vance since 1990. Each has been a Vice President of Eaton Vance since 1992 and has been involved in the management of Senior Loans throughout his tenure at Eaton Vance. They currently co-manage Senior Debt Portfolio (described above) with assets of approximately $5.8 billion on October 21, 1998.

19

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

The Trust has engaged Eaton Vance to act as its administrator under an Administration Agreement (the "Administration Agreement"). Under the Administration Agreement, Eaton Vance is responsible for managing the business affairs of the Trust, subject to the supervision of the Trust's Board of Trustees. Eaton Vance will furnish to the Trust all office facilities, equipment and personnel for administering the affairs of the Trust. 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 Trust's custodian and transfer agent, providing assistance in connection with the Trustees' and shareholders' meetings, providing service in connection with any repurchase offers and other administrative services necessary to conduct the Trust's business. In return for these services, facilities and payments, the Trust is authorized to pay Eaton Vance as compensation under the Administration Agreement a fee in the amount of .25% of the average weekly gross assets of the Trust. The Administrator has agreed to waive its administration fee for the two-month period following the date of this Prospectus.

DISTRIBUTIONS AND TAXES

The Trust intends to make monthly distributions of net investment income, after payment of interest on any outstanding borrowings or dividends on any outstanding preferred shares. The Trust will distribute annually any net short-term capital gain and any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss). Distributions to Shareholders cannot be assured, and the amount of each monthly distribution is likely to vary. Initial distributions to Shareholders are expected to be paid approximately 60 days after the completion of this offering. While there are any borrowings or preferred shares outstanding, the Trust may not be permitted to declare any cash dividend or other distribution on its Shares in certain circumstances. See "Description of Capital Structure."

Distributions of the Trust's investment company taxable income (consisting generally of net investment income and net short-term capital gain) are taxable to Shareholders as ordinary income, whether paid in cash or reinvested in additional Shares. Distributions of the Trust's net capital gain ("capital gain dividends"), if any, are taxable to Shareholders at the rates applicable to long-term capital gains, regardless of the length of time Shares have been held by Shareholders. Distributions, if any, in excess of the Trust's earnings and profits will first reduce the adjusted tax basis of a holder's Shares and, after such adjusted tax basis has been reduced to zero, will constitute capital gains to such holder (assuming such Shares are held as a capital asset). See below for a summary of the maximum tax rates applicable to capital gains (including capital gain dividends).

The Trust will inform Shareholders of the source and tax status of all distributions promptly after the close of each calendar year. The Trust's distributions will not qualify for the dividends-received deduction for corporations.

Selling Shareholders will generally recognize gain or loss in an amount equal to the difference between their adjusted tax basis in the Shares and the amount received. If such 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 capital assets held for one year or less or (ii) 20% for capital assets held for more than one year. Any loss recognized upon a taxable disposition of Shares held for six months or less will be treated as a long-term capital loss to the extent of any capital gain dividends received with respect to such Shares. For purposes of determining whether Shares have been held for six months or less, the holding period is suspended for any periods during which the 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 Shares will be disallowed to the extent those Shares are replaced by other Shares within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the

20

Shares (which could occur, for example, if the Shareholder is a participant in the Plan (as defined below)). In that event, the basis of the replacement Shares will be adjusted to reflect the disallowed loss.

An investor should be aware that if Shares are purchased in the open market shortly before the record date for any dividend (including a capital gain dividend), 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 Shares, in effect resulting in a taxable return of some of the purchase price. Shareholders that are not liable for tax on their income and whose Shares are not debt-financed are not required to pay tax on dividends they receive from the Trust. Taxable distributions to individuals and certain other non-corporate 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 of 31%.

The foregoing briefly summarizes some of the important federal income tax consequences to Shareholders of investing in Shares and does not address special tax rules applicable to certain types of investors, such as corporate and foreign investors, individual retirement accounts and other retirement plans. There may be other federal, state, local or foreign tax considerations applicable to a particular investor. Investors should consult their tax advisers.

DIVIDEND REINVESTMENT PLAN

Pursuant to the Trust's Dividend Reinvestment Plan (the "Plan"), unless a Shareholder otherwise elects, all distributions of dividends (including all capital gain dividends) will be automatically reinvested in Shares.

First Data Investor Services Group (the "Plan Agent") serves as agent for the Shareholders in administering the Plan. Shareholders who elect not to participate in the Plan will receive all distributions of dividends in cash paid by check mailed directly to the Shareholder of record (or if the Shares are held in street or other nominee name, then to the nominee) by First Data Investor Services Group 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 not less than ten days prior to any dividend record date.

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 Shares from the Trust ("newly issued shares") or (ii) by purchase of outstanding Shares on the open market ("open-market purchases") on the New York Stock Exchange or elsewhere. If on the payment date for the dividend, the net asset value per Share is equal to or less than the market price per Share plus estimated brokerage commissions (such condition being referred to herein as "market premium"), the Plan Agent will invest the dividend amount in newly issued Shares on behalf of the participants. The number of newly issued Shares to be credited to each participant's account will be determined by dividing the dollar amount of the dividend by the net asset value per Share on the date the Shares are issued, provided that the maximum discount from the then current market price per Share on the date of issuance may not exceed 5%. If on the dividend payment date the net asset value per 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 dividend amount in Shares acquired on behalf of the participants in open-market purchases.

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

21

The Plan Agent maintains all Shareholders' accounts in the Plan and furnishes written confirmation of all transactions in the accounts, including information needed by Shareholders for tax records. Shares in the account of each Plan participant will be held by the Plan Agent on behalf of the Plan participant, and each Shareholder proxy will include those Shares purchased or received pursuant to the Plan. The Plan Agent will forward all proxy solicitation materials to participants and vote proxies for Shares held pursuant to the Plan in accordance with the instructions of the participants.

In the case of Shareholders such as banks, brokers or nominees that hold Shares for others who are the beneficial owners, the Plan Agent will administer the Plan on the basis of the number of Shares certified from time to time by the record 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 Shares issued directly by the Trust as a result of dividends payable either in Shares or in cash. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent's open-market purchases in connection with the reinvestment of dividends.

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

Experience under the Plan may indicate that changes are desirable. Accordingly, the Trust reserves the right to amend or terminate the Plan. There is no direct service charge to participants in the Plan; however, the Trust reserves the right to amend the Plan to include a service charge payable by the participants.

All correspondence concerning the Plan should be directed to the Plan Agent at P. O. Box 8030, Boston, MA 02266-8030. 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 Trust is an unincorporated business trust established under the laws of The Commonwealth of Massachusetts by an Agreement and Declaration of Trust dated September 23, 1998 (the "Declaration of Trust"). The Declaration of Trust provides that the Trustees of the Trust may authorize separate classes of shares of beneficial interest. The Trustees have authorized an unlimited number of Shares. The Declaration of Trust also authorizes the Trust to borrow money or otherwise obtain credit and in this connection issue notes or other evidence of indebtedness. The Trust intends to hold annual meetings of the holders of Shares in compliance with the requirements of the New York Stock Exchange.

Shares. The Declaration of Trust permits the Trust to issue an unlimited number of full and fractional Shares of beneficial interest, $0.01 par value per Share. Each Share represents an equal proportionate interest in the assets of the Trust with each other Share in the Trust. Holders of Shares will be entitled to the payment of dividends when, as and if declared by the Board of Trustees. The 1940 Act or the terms of any borrowings or preferred shares may limit the payment of dividends to the holders of Shares. Each whole 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 Trust, after paying or adequately providing for the payment of all liabilities of the Trust 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 Trustees may distribute the remaining assets of the Trust among the holders of the Shares. The Declaration of Trust provides that Shareholders are not liable for any liabilities of the Trust,

22

requires inclusion of a clause to that effect in every agreement entered into by the Trust and indemnifies shareholders against any such liability. Although shareholders of an unincorporated business trust established under Massachusetts law, in certain limited circumstances, may be held personally liable for the obligations of the trust as though they were general partners, the provisions of the Declaration of Trust described in the foregoing sentence make the likelihood of such personal liability remote.

While there are any borrowings or preferred shares outstanding, the Trust may not be permitted to declare any cash dividend or other distribution on its Shares, unless at the time of such declaration, (i) all accrued dividends on preferred shares or accrued interest on borrowings has been paid and (2) the value of the Trust's total assets (determined after deducting the amount of such dividend or other distribution), less all liabilities and indebtedness of the Trust not represented by senior securities, is at least 300% of the aggregate amount of such securities representing indebtedness and at least 200% of the aggregate amount of securities representing indebtedness plus the aggregate liquidation value of the outstanding preferred shares (expected to equal the aggregate original purchase price of the outstanding preferred shares plus redemption premium, if any, together with any accrued and unpaid dividends thereon, whether or not earned or declared and on a cumulative basis). In addition to the requirements of the 1940 Act, the Trust may be required to comply with other asset coverage requirements as a condition of the Trust obtaining a rating of the preferred shares from a Rating Agency or as a condition to borrowing money. These requirements may include an asset coverage test more stringent than under the 1940 Act. This limitation on the Trust's ability to make distributions on its Shares could in certain circumstances impair the ability of the Trust to maintain its qualification for taxation as a regulated investment company. The Trust intends, however, to the extent possible to purchase or redeem preferred shares or to repay borrowings from time to time to maintain compliance with such asset coverage requirements and may pay special dividends to the holders of the preferred shares in certain circumstances in connection with any such impairment of the Trust's status as a regulated investment company. See "Investment Objective, Policies and Risks" and "Distributions and Taxes." Depending on the timing of any such redemption or repayment, the Trust may be required to pay a premium in addition to the liquidation preference of the preferred shares or the principal amount of the borrowings to the holders thereof. See "--Borrowings" below.

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

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

Repurchase Of Shares and Other Discount Corrective Measures. Because shares of closed-end management investment companies frequently trade at a discount to their net asset values, the Board of Trustees has determined that from time to time it may be in the interest of Shareholders for the Trust to take corrective actions. The Board of Trustees, in consultation with Eaton Vance, will review at least annually the possibility of open market repurchases and/or tender offers for the Shares and will consider such factors as the market price of the Shares, the net asset value of the Shares, the liquidity of the assets of the Trust, effect on the Trust's expenses, whether such transactions would impair the Trust'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 which may have a material effect on the Trust's ability to consummate such transactions. There are no assurances that the Board of Trustees will, in fact, decide to undertake either of these actions or if undertaken, that such actions will result in the Trust's Shares trading at a price which is equal to or approximates their net asset value. In recognition of the possibility that the Shares might trade at a discount to net asset value and that any such discount may not be in the interest of Shareholders, the Board of Trustees, in consultation with Eaton Vance, from time to time may review possible actions to reduce any such discount.

23

Borrowings. The Declaration of Trust authorizes the Trust, without prior approval of the Shareholders, to borrow money in an amount up to 33 1/3% of the Trust's total assets (including the amount borrowed). In this regard, the Trust may issue notes or other evidence of indebtedness (including bank borrowings or commercial paper) and may secure any such borrowings by mortgaging, pledging or otherwise subjecting as security the Trust's assets. In connection with such borrowing, the Trust may be required to maintain minimum average balances with the lender or to pay a commitment or other fee to maintain a line of credit. Any such requirements will increase the cost of borrowing over the stated interest rate. Under the requirements of the 1940 Act, the Trust, immediately after any such borrowings, must have an "asset coverage" of at least 300%. With respect to any such borrowing, asset coverage means the ratio which the value of the total assets of the Trust, less all liabilities and indebtedness not represented by senior securities (as defined in the 1940 Act), bears to the aggregate amount of such borrowing represented by senior securities by the Trust. Certain types of borrowing may result in the Trust being subject to covenants in credit agreements relating to asset coverages or portfolio composition or otherwise. Such restrictions may be more stringent than those imposed by the 1940 Act. The rights of lenders to the Trust to receive interest on and repayment of principal of any such borrowings will be senior to those of the Shareholders, and the terms of any such borrowings may contain provisions which limit certain activities of the Trust, including the payment of dividends to Shareholders in certain circumstances. Further, the terms of any such borrowing may and the 1940 Act does (in certain circumstances) grant to the lenders to the Trust certain voting rights in the event of default in the payment of interest on or repayment of principal. In the event that such provisions would impair the Trust's status as a regulated investment company, the Trust, subject to its ability to liquidate its relatively illiquid portfolio, intends to repay the borrowings. Any borrowing will likely rank senior to or pari passu (on the same level as) with all other existing and future borrowings of the Trust. See "Investment Objective, Policies and Risks -- Use of Leverage and Related Risks." The Trust may also borrow up to an additional 5% of its total assets for temporary purposes, as permitted by the 1940 Act.

The Trust currently expects that it may enter into definitive agreements with respect to a credit facility shortly after the closing of the offer and sale of the Shares offered hereby. The Trust is currently in negotiations with a limited number of large commercial banks to arrange a credit facility pursuant to which the Trust expects to be entitled to borrow an amount equal to approximately 33 1/3 of the Trust's total assets (inclusive of the amount borrowed) as of the closing of the offer and sale of the Shares offered hereby. Any such borrowings would constitute financial leverage. The terms of any agreements relating to such a credit facility have not been determined and are subject to definitive agreement and other conditions but the Trust anticipates that such a credit facility would have terms substantially similar to the following: (i) a final maturity not expected to exceed three years, subject to possible extension by the Trust; (ii) with respect to each draw under the facility, an interest rate equal to the lesser of LIBOR plus a stated premium or an alternate rate on the outstanding amount of each such draw, reset over periods ranging from one to six months; and (iii) payment by the Trust of certain fees and expenses including an underwriting fee, a commitment fee on the average undrawn amount of the facility, an ongoing administration fee and the expenses of the lenders under the facility incurred in connection therewith. The facility is not expected to be convertible into any other securities of the Trust, outstanding amounts are expected to be prepayable by the Trust prior to final maturity without significant penalty and there are not expected to be any sinking fund or mandatory retirement provisions. Outstanding amounts would be payable at maturity or such earlier times as required by the agreement. The Trust may be required to prepay outstanding amounts under the facility or incur a penalty rate of interest in the event of the occurrence of certain events of default. The Trust expects to indemnify the lenders under the facility against liabilities they may incur in connection with the facility. In addition the Trust expects that such a credit facility would contain covenants which, among other things, likely will limit the Trust's ability to pay dividends 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 Trust may be required to maintain a portion of its assets in cash or high-grade securities as a reserve against interest or principal payments and expenses. The Trust expects that any credit facility would have customary covenant, negative covenant and default provisions. There can be no assurance that the Trust will enter into an agreement for a credit facility on terms and conditions representative of the foregoing, or that additional material terms will not apply. In

24

addition, if entered into, any such credit facility 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.

Preferred Shares. The Declaration of Trust authorizes the issuance of an unlimited number of shares of beneficial interest with preference rights, including preferred shares (the "Preferred Shares"), having a par value of $0.01 per share, in one or more series, with rights as determined by the Board of Trustees, by action of the Board of Trustees without the approval of the Shareholders.

Under the requirements of the 1940 Act, the Trust 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 Trust, 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 Trust, if any, plus the aggregate liquidation preference of the Preferred Shares. If the Trust seeks a rating of the Preferred Shares, asset coverage requirements, in addition to those set forth in the 1940 Act, may be imposed. The liquidation value of the Preferred Shares is expected to equal their aggregate original purchase price plus redemption premium, if any, together with any accrued and unpaid dividends thereon (on a cumulative basis), whether or not earned or declared. The terms of the Preferred Shares, including their dividend rate, voting rights, liquidation preference and redemption provisions, will be determined by the Board of Trustees (subject to applicable law and the Trust's Declaration of Trust) if and when it authorizes the Preferred Shares. The Trust may issue Preferred Shares that provide for the periodic redetermination of the dividend rate at relatively short intervals through an auction or remarketing procedure, although the terms of the Preferred Shares may also enable the Trust to lengthen such intervals. At times, the dividend rate as redetermined on the Trust's Preferred Shares may approach or exceed the Trust's return after expenses on the investment of proceeds from the Preferred Shares and the Trust's leverage structure would result in a lower rate of return to Shareholders than if the Trust were not so structured. However, the Trust believes that the floating rate nature of Senior Loans in which the Trust invests helps mitigate against the risks of increased dividend costs as a result of redetermined market rates adversely impacting the return to Shareholders.

In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Trust, 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 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 Trust.

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 Trust or to change the composition of its Board of Trustees, and could have the effect of depriving Shareholders of an opportunity to sell their Shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Trust. These provisions may have the effect of discouraging attempts to acquire control of the Trust, which attempts could have the effect of increasing the expenses of the Trust and interfering with the normal operation of the Trust. The Board of Trustees is divided into three classes, with the term of one class expiring at each annual meeting of 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 of Trustees. 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 Trust that elected such Trustee and is entitled to vote on the matter.

In addition, the Declaration of Trust requires the favorable vote of the holders of at least 75% of the outstanding shares of each class of the Trust, 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 of Trustees 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

25

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 Trust. The transactions subject to these special approval requirements are:
(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 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 Trust or any subsidiary thereof, in exchange for securities of the Trust, 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 of Trustees 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 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 Trust may be converted to an open-end investment company at any time if approved by the lesser of (i) 2/3 or more of the Trust's then outstanding Shares and preferred shares (if any), each voting separately as a class, or (ii) more than 50% of the then outstanding 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 Trust 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. The composition of the Trust's portfolio likely would prohibit the Trust from complying with regulations of the SEC applicable to open-end investment companies. Accordingly, conversion likely would require significant changes in the Trust's investment policies and liquidation of a substantial portion of its relatively illiquid portfolio. Conversion of the Trust to an open-end investment company also would require the redemption of any outstanding Preferred Shares and could require the repayment of borrowings, which would eliminate the leveraged capital structure of the Trust with respect to the Shares. In the event of conversion, the Shares would cease to be listed on the New York Stock Exchange or other national securities exchange or market system. The Board of Trustees believes, however, that the closed-end structure is desirable, given the Trust's investment objective and policies. Investors should assume, therefore, that it is unlikely that the Board of Trustees would vote to convert the Trust to an open-end investment company. Shareholders of an open-end 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. The Trust expects to pay all such redemption requests in cash, but intends to 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 Trust were converted to an open-end fund, it is likely that new Shares would be sold at net asset value plus a sales load.

The Trust has granted to the Underwriters an option, exercisable for 45 days from the date of this Prospectus to purchase up to an additional Shares to cover over-allotments, if any, at the initial offering price. The Underwriters may exercise such option solely for the purpose of covering over-allotments incurred in the sale of the 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 Shares proportionate to such Underwriter's initial commitment.

As set forth in the notes to the table on the cover page of this Prospectus, Eaton Vance or an affiliate (not the Trust) from its own assets has agreed to pay a commission to the Underwriters in the amount of $0.45 per Share (4.50% of the public offering price per Share) or an aggregate amount of $ ($ assuming full exercise of the over-allotment option) for all Shares covered by this Prospectus. Such payment will be the legal obligation of Eaton Vance or an affiliate and made out of its own assets and will not in any way represent an obligation of the Trust or its Shareholders. The Representatives have advised the Trust that the Underwriters may pay up to $ per Share from such payment received from Eaton Vance to selected dealers who sell the Shares and that the Underwriters and such dealers may reallow a concession of up to $ per Share to certain other dealers who sell Shares. Eaton Vance (or an affiliate) has agreed to pay all offering expenses of the Trust that exceed $0.02 per share.

Prior to this offering, there has been no public market for the Shares or any other securities of the Trust. The Trust has applied for listing of its Shares on the New York Stock Exchange under the symbol "EVF." In order to meet the requirements for listing the Shares on the New York Stock Exchange, the Underwriters have undertaken to sell lots of 100 or more Shares to a minimum of 2,000 beneficial holders. The minimum investment requirement is 100 Shares ($1,000).

The Trust and Eaton Vance 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 Trust has agreed not to offer or sell any additional Shares of the Trust, other than as contemplated by this Prospectus, for a period of 180 days after the date of the Underwriting Agreement without the prior written consent of the Underwriters.

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

The Underwriters may take certain actions to discourage short-term trading of Shares during a period of time following the initial offering date. Included in these actions is the withholding of the concession and other payments to dealers in connection with Shares which were sold by such dealers and which are repurchased for the account of the Underwriters during such period. In addition, physical delivery of certificates representing Shares is required to transfer ownership of Shares for a certain period. Until the distribution of Shares is completed, rules of the SEC may limit the ability of the Underwriters and certain selling group members to

28

bid for and purchase the Shares. As an exception to these rules, the Underwriters are permitted to engage in certain transactions that stabilize the price of the Shares. Such transactions consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the Shares. If the Underwriters create a short position in the Shares in connection with the offering, i.e., if they sell more Shares than are set forth on the cover page of this Prospectus, then the Underwriters may reduce that short position by purchasing Shares in the open market. The Underwriters may also elect to reduce any short position by exercising all or a part of the over-allotment option described above. In general, purchases of a security for the purpose of stabilization or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases. In addition, the Underwriters may impose "penalty bids" under contractual arrangements with dealers participating in the offering whereby it may reclaim the selling concession with respect to Shares distributed in the offering but subsequently purchased for the account of the Underwriters in the open market. Neither the Trust nor the Underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Shares. In addition, neither the Trust nor the Underwriters make any representation that the Underwriters will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice.

Under the terms of and subject to the conditions of the Underwriting Agreement, the Underwriters are committed to purchase and pay for all Shares offered hereby if any are purchased. The Underwriting Agreement provides that it may be terminated at or prior to the closing date for the purchase of the Shares if, in the judgement of the Representatives, payment for the delivery of the Shares is rendered impracticable or inadvisable because (1) trading in the equity securities of the Trust is suspended by the SEC, by an exchange that lists the Shares, or by the National Association of Securities Dealers Automated Quotation National Market System ("NASDAQ"), (2) trading in securities generally on the New York Stock Exchange or NASDAQ shall have been suspended or limited or minimum or maximum prices shall have been generally established on such exchange or over-the-counter market, (3) additional material governmental restrictions, not in force on the date of the Underwriting Agreement, have been imposed upon trading in securities generally or trading in securities generally has been suspended on any U.S. securities exchange, (4) a general banking moratorium has been established by Federal or New York authorities, or (5) any material adverse change in the financial or securities markets in the United States or in political, financial or economic conditions in the United States or any outbreak or material escalation of hostilities or other calamity or crisis occurs, the effect of which is such as to make it impracticable to market any or all of the Shares. The Underwriting Agreement also may be terminated if any of the conditions specified in the Underwriting Agreement have not been fulfilled when and as required by such agreement.

The Trust 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.

As described below under "Shareholder Servicing Agent, Custodian and Transfer Agent," Painewebber Incorporated will provide shareholder services to the Trust pursuant to a Shareholder Servicing Agreement with Eaton Vance.

ADDITIONAL INVESTMENT INFORMATION AND RESTRICTIONS

Lending Fees. In the process of buying, selling and holding Senior Loans the Trust may receive and/or pay certain fees. These fees are in addition to interest payments received and may include facility fees, commitment fees, commissions and prepayment penalty fees. When the Trust buys a Senior Loan it may receive a facility fee and when it sells a Senior Loan it may pay a facility fee. On an ongoing basis, the Trust may receive a commitment fee based on the undrawn portion of the underlying line of credit portion of a Senior Loan. In certain circumstances, the Trust may receive a prepayment penalty fee upon the prepayment of a Senior Loan by a Borrower. Other fees received by the Trust may include covenant waiver fees and covenant modification fees.

Borrower Covenants. A Borrower must comply with various restrictive covenants contained in a loan agreement or note purchase agreement between the Borrower and the Lender or lending syndicate (the "Loan Agreement"). Such covenants, in addition to requiring the scheduled payment of interest and principal, may include restrictions on dividend payments and other distributions to stockholders, provisions requiring the Borrower to maintain specific minimum financial ratios, and limits on total debt. In addition, the Loan Agreement may contain a covenant requiring the Borrower to prepay the Senior Loan with any free cash flow. Free cash flow is generally defined as net cash flow after scheduled debt service payments and permitted capital expenditures, and includes the proceeds from asset dispositions or sales of securities. A breach of a covenant which is not waived by the Agent, or by the lenders directly, as the case may be, is normally an event of acceleration; i.e., the Agent, or the lenders directly, as the case may be, has the right to call the outstanding Senior Loan. The typical practice of an Agent or a Lender in relying exclusively or primarily on reports from the Borrower may involve a risk of fraud by the Borrower. In the case of a Senior Loan in the form of a Participation, the agreement between the buyer and seller may limit the rights of the holder of a Senior Loan to vote on certain changes which may be made to the Loan Agreement, such as waiving a breach of a covenant. However, the holder of the Participation will, in almost all cases, have the right to vote on certain fundamental issues such as changes in principal amount, payment dates and interest rate.

Administration of Loans. In a typical Senior Loan, the Agent administers the terms of the Loan Agreement. In such cases, the Agent is normally responsible for the collection of principal and interest payments from the Borrower and the apportionment of these payments to the credit of all institutions which are parties to the Loan Agreement. The Trust will generally rely upon the Agent or an intermediate participant to receive and forward to the Trust its portion of the principal and interest payments on the Senior Loan. Furthermore, unless under the terms of a Participation Agreement the Trust has direct recourse against the Borrower, the Trust will rely on the Agent and the other members of the lending syndicate to use appropriate credit remedies against the Borrower. The Agent is typically responsible for monitoring compliance with covenants contained in the Loan Agreement based upon reports prepared by the Borrower. The seller of the Senior Loan usually does, but is often not obligated to, notify holders of Senior Loans of any failures of compliance. The Agent may monitor the value of the collateral and, if the value of the collateral declines, may accelerate the Senior Loan, may give the Borrower an opportunity to provide additional collateral or may seek other protection for the benefit of the participants in the Senior Loan. The Agent is compensated by the Borrower for providing these services under a Loan Agreement, and such compensation may include special fees paid upon structuring and funding the Senior Loan and other fees paid on a continuing basis. With respect to Senior Loans for which the Agent does not perform such administrative and enforcement functions, the Trust will perform such tasks on its own behalf, although a collateral bank will typically hold any collateral on behalf of the Trust and the other lenders pursuant to the applicable Loan Agreement.

A financial institution's appointment as Agent may usually be terminated in the event that it fails to observe the requisite standard of care or becomes insolvent, enters Federal Deposit Insurance Corporation ("FDIC") receivership, or, if not FDIC insured, enters into bankruptcy proceedings. A successor Agent would generally be appointed to replace the terminated Agent, and assets held by the Agent under the Loan

B-2

Agreement should remain available to holders of Senior Loans. However, if assets held by the Agent for the benefit of the Trust were determined to be subject to the claims of the Agent's general creditors, the Trust might incur certain costs and delays in realizing payment on a Senior Loan, or suffer a loss of principal and/or interest. In situations involving other intermediate participants similar risks may arise.

Prepayments. Senior Loans usually require, in addition to scheduled payments of interest and principal, the prepayment of the Senior Loan from free cash flow, as defined above. The degree to which Borrowers prepay Senior Loans, whether as a contractual requirement or at their election, may be affected by general business conditions, the financial condition of the Borrower and competitive conditions among lenders, among others. As such, prepayments cannot be predicted with accuracy. Upon a prepayment, either in part or in full, the actual outstanding debt on which the Trust derives interest income will be reduced. However, the Trust may receive both a prepayment penalty fee from the prepaying Borrower and a facility fee upon the purchase of a new Senior Loan with the proceeds from the prepayment of the former. Prepayments generally will not materially affect the Trust's performance because the Trust should be able to reinvest prepayments in other Senior Loans that have similar or identical yields and because receipt of such fees may mitigate any adverse impact on the Trust's yield.

Other Information Regarding Senior Loans. From time to time, the Adviser and its affiliates may borrow money from various banks in connection with their business activities. Such banks may also sell Senior Loans to or acquire them from the Trust or may be intermediate participants with respect to Senior Loans in which the Trust owns interests. Such banks may also act as Agents for Senior Loans held by the Trust.

The Trust may acquire interests in Senior Loans which are designed to provide temporary or "bridge" financing to a Borrower pending the sale of identified assets or the arrangement of longer-term loans or the issuance and sale of debt obligations. The Trust may also invest in Senior Loans of Borrowers who have obtained bridge loans from other parties. A Borrower's use of bridge loans involves a risk that the Borrower may be unable to locate permanent financing to replace the bridge loan, which may impair the Borrower's perceived creditworthiness.

To the extent that collateral consists of the stock of the Borrower's subsidiaries or other affiliates, the Trust will be subject to the risk that this stock will decline in value. Such a decline, whether as a result of bankruptcy proceedings or otherwise, could cause the Senior Loan to be undercollateralized or unsecured. In most credit agreements there is no formal requirement to pledge additional collateral. In addition, the Trust may invest in Senior Loans guaranteed by, or fully secured by assets of, shareholders or owners, even if the Senior Loans are not otherwise collateralized by assets of the Borrower; provided, however, that such guarantees are fully secured. There may be temporary periods when the principal asset held by a Borrower is the stock of a related company, which may not legally be pledged to secure a Senior Loan. On occasions when such stock cannot be pledged, the Senior Loan will be temporarily unsecured until the stock can be pledged or is exchanged for or replaced by other assets, which will be pledged as security for the Senior Loan. However, the Borrower's ability to dispose of such securities, other than in connection with such pledge or replacement, will be strictly limited for the protection of the holders of Senior Loans. During any such period in which the Senior Loan is temporarily unsecured, such Senior Loans will not be treated as secured Senior Loans for purposes of the Trust's policy of investing in normal market conditions at least 80% of its total assets in such secured Senior Loans.

If a Borrower becomes involved in bankruptcy proceedings, a court may invalidate the Trust's security interest in the loan collateral or subordinate the Trust's rights under the Senior Loan to the interests of the Borrower's unsecured creditors. Such action by a court could be based, for example, on a "fraudulent conveyance" claim to the effect that the Borrower did not receive fair consideration for granting the security interest in the loan collateral to the Trust. For Senior Loans made in connection with a highly leveraged transaction, consideration for granting a security interest may be deemed inadequate if the proceeds of the Loan were not received or retained by the Borrower, but were instead paid to other persons (such as shareholders of the Borrower) in an amount which left the Borrower insolvent or without sufficient working capital. There are also other events, such as the failure to perfect a security interest due to faulty documentation or faulty official filings, which could lead to the invalidation of the Trust's security interest in

B-3

loan collateral. If the Trust's security interest in loan collateral is invalidated or the Senior Loan is subordinated to other debt of a Borrower in bankruptcy or other proceedings, it is unlikely that the Trust would be able to recover the full amount of the principal and interest due on the Loan.

Interest Rate Swaps. The Trust may enter into interest rate swaps on either an asset-based or liability-based basis, depending on whether it is hedging its assets or its liabilities. For example, if the Trust holds a Senior Loan with an interest rate that is reset only once each year, it may swap the right to receive interest at this fixed rate for the right to receive interest at a rate that is reset daily. Such a swap position would offset changes in the value of the Senior Loan because of subsequent changes in interest rates. This would protect the Trust from a decline in the value of the Senior Loan due to rising interest rates, but would also limit its ability to benefit from falling interest rates.

The Trust will enter into interest rate swaps only on a net basis, i.e., the two payment streams are netted out, with the Trust receiving or paying, as the case may be, only the net amount of the two payments. Inasmuch as these transactions are entered into for good faith hedging and risk management purposes and because a segregated account will be used, the Trust will not treat them as being subject to the Trust's borrowing restrictions. The net amount of the excess, if any, of the Trust's obligations over its entitlements with respect to each interest rate swap will be accrued on a daily basis and an amount of cash or liquid securities having an aggregate net asset value at least equal to the accrued excess will be maintained in a segregated account by the Trust's custodian. The Trust will not enter into any interest rate swap unless the credit quality of the unsecured senior debt or 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 Trust will have contractual remedies pursuant to the agreements related to the transaction. The swap market has grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. As a result, the swap market has become relatively liquid in comparison with the markets for other similar instruments which are traded in the interbank market.

Interest rate swaps do not involve the delivery of securities or other underlying assets or principal. Accordingly, the risk of loss with respect to interest rate swaps is limited to the net amount of interest payments that the Trust is contractually obligated to make or receive. Since interest rate swaps are individually negotiated, the Trust expects to achieve an acceptable degree of correlation between its rights to receive interest on Senior Loans and its rights and obligations to receive and pay interest pursuant to interest rate swaps.

Credit Derivatives. The Trust may engage in credit derivative transactions. Default price risk derivatives are linked to the price of reference securities or loans after a default by the issuer or borrower, respectively. Market spread derivatives are based on the risk that changes in market factors, such as credit spreads, can cause a decline in the value of a security, loan or index. There are three basic transactional forms for credit derivatives; swaps, options and structured instruments. The use of credit derivatives is a highly specialized activity which involves strategies and risks different from those associated with ordinary portfolio security transactions. If the Adviser is incorrect in its forecasts of default risks, market spreads or other applicable factors, the investment performance of the Trust would diminish compared with what it would have been if these techniques were not used. Moreover, even if the Adviser is correct in its forecasts, there is a risk that a credit derivative position may correlate imperfectly with the price of the asset or liability being hedged. Credit derivative transaction exposure will be limited to 10% of the total assets of the Trust.

B-4

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

(1) Borrow money, except as permitted by the 1940 Act;

(2) Issue senior securities, as defined in the 1940 Act, other than
(i) preferred shares which immediately after issuance will have asset coverage of at least 200%, (ii) indebtedness which immediately after issuance will have asset coverage of at least 300%, or (iii) the borrowings permitted by investment restriction (1) above;

(3) Purchase securities on margin (but the Trust may obtain such short-term credits as may be necessary for the clearance of purchases and sales of securities). The purchase of loan interests, securities or other 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 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 Trust is authorized to invest in accordance with its investment objective and policies, (b) entering into repurchase agreements, and (c) lending its portfolio securities;

(6) Purchase any security if, as a result of such purchase, 25% or more of the Trust's total assets (taken at current value) would be invested in the securities of borrowers and other issuers having their principal business activities in the same industry (the electric, gas, water and telephone utility industries, commercial banks, thrift institutions and finance companies being treated as separate industries for the purpose of this restriction); provided that there is no limitation with respect to obligations issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities;

(7) 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 Trust reserves the freedom of action to hold and to sell real estate acquired as a result of the ownership of securities; or

(8) 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 or other financial instruments.

For the purpose of investment restriction (6), the Trust will consider all relevant factors in determining who is the issuer of the loan interest, including: the credit quality of the Borrower, the amount and quality of the collateral, the terms of the Loan Agreement and other relevant agreements (including inter-creditor agreements), the degree to which the credit of such interpositioned person was deemed material to the decision to purchase the Senior Loan, the interest rate environment, and general economic conditions applicable to the Borrower and such interpositioned person.

The Trust has adopted the following nonfundamental investment policy which may be changed by the Trustees without approval of the Trust's shareholders. As a matter of nonfundamental policy, the Trust 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.

Notwithstanding the investment policies and restrictions of the Trust, upon Board of Trustee approval the Trust may invest its investable assets in one or more other management investment companies to the extent permitted by the 1940 Act and rules thereunder.

B-5

Whenever an investment policy or investment restriction set forth in the Prospectus or this Statement of Additional Information states a maximum percentage of assets that may be invested in any security or other asset or describes a policy regarding quality standards, such percentage limitation or standard shall be determined immediately after and as a result of the Trust's acquisition of such security or asset. Accordingly, any later increase or decrease resulting from a change in values, assets or other circumstances will not compel the Trust to dispose of such security or other asset. Notwithstanding the foregoing, the Trust must always be in compliance with the borrowing policies set forth above.

(3) Class III Trustee whose term expires in 2001.

Messrs. Hayes (Chairman), Reamer and Thorndike are members of the Special Committee of the Board of Trustees of the Trust. The purpose of the Special Committee is to consider, evaluate and make recommendations to the full Board of Trustees concerning (i) all contractual arrangements with service providers to the Trust, including investment advisory, administrative, transfer agency, custodial and fund accounting and distribution services, and (ii) all other matters in which Eaton Vance or its affiliates has any actual or potential conflict of interest with the Trust or its shareholders.

The Nominating Committee of the Board of Trustees of the Trust is comprised of four Trustees who are not "interested persons" as that term is defined under the 1940 Act ("noninterested Trustees"). The Committee has four-year staggered terms, with one member rotating off the Committee to be replaced by another noninterested Trustee. The purpose of the Committee is to recommend to the Board nominees for the position of noninterested Trustee and to assure that at least a majority of the Board of Trustees is independent of Eaton Vance and its affiliates.

Messrs. Treynor (Chairman) and Dwight are members of the Audit Committee of the Board of Trustees of the Trust. The Audit Committee's functions include making recommendations to the Trustees regarding the selection of the independent certified public accountants, and reviewing matters relative to trading and brokerage policies and practices, accounting and auditing practices and procedures, accounting records,

B-7

internal accounting controls, and the functions performed by the custodian, transfer agent and dividend disbursing agent of the Trust.

Trustees of the Trust 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 Trust 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 Trust's assets, liabilities, and net income per share, and will not obligate the Trust to retain the services of any Trustee or obligate the Trust to pay any particular level of compensation to the Trustee. The Trust does not have a retirement plan for its Trustees.

The fees and expenses of the noninterested Trustees of the Trust are paid by the Trust. (The Trustees of the Trust who are members of the Eaton Vance organization receive no compensation from the Trust.) During the year ended December 31, 1997, the noninterested Trustees of the Trust earned the compensation set forth below in their capacities as Trustees from the funds in the Eaton Vance fund complex(1). It is estimated that the noninterested Trustees will receive from the Trust the amounts set forth below for the fiscal year ending June 30, 1999.

                                                       ESTIMATED        TOTAL COMPENSATION

INVESTMENT ADVISORY AND OTHER SERVICES

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 and equity investment professionals to service the needs of their clients. The fixed-income division 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 equity division 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, including corporations, hospitals, retirement plans, universities, foundations and trusts.

The Trust 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 Trust 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; expenses of reports to shareholders, proxy statements and other expenses of shareholders' meetings; insurance premiums; printing and mailing expenses;

B-8

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 Trust shares; and investment advisory and administration fees. The Trust will also bear expenses incurred in connection with any litigation in which the Trust 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 February 28, 2000 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 Trust 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 Trust or by vote of a majority of the outstanding interests of the Trust. The Trust'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 Trust's Trustees. Each agreement may be terminated at any time without penalty on sixty (60) days' written notice by the Trustees of the Trust or Eaton Vance, as applicable, or by vote of the majority of the outstanding shares of the Trust. 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 Trust under such agreements on the part of Eaton Vance, Eaton Vance shall not be liable to the Trust for any loss incurred, to the extent not covered by insurance.

BMR and Eaton Vance are business trusts organized under Massachusetts law. Eaton Vance, Inc. ("EV") serves as trustee of BMR and Eaton Vance. BMR, Eaton Vance and EV are wholly-owned subsidiaries of Eaton Vance Corporation ("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 M. Dozier Gardner, James B. Hawkes, Benjamin A. Rowland, Jr., John G.L. Cabot, John M. Nelson, Vincent M. O'Reilly and Ralph Z. Sorenson. All of the issued and outstanding shares of Eaton Vance are owned by EVC. All of the issued and outstanding shares of BMR are owned by Eaton Vance. All shares of the outstanding Voting Common Stock of EVC are deposited in a Voting Trust, the Voting Trustees of which are Messrs. Gardner, Hawkes, Rowland, and Alan R. Dynner, Thomas E. Faust, Jr., William M. Steul and Wharton P. Whitaker. 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 Trust (as well as Mr. Hawkes who is also a Trustee) hold positions in the Eaton Vance organization.

EVC and its affiliates and their officers and employees from time to time have transactions with various banks, including the custodian of the Trust, 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 Trust and such banks.

DETERMINATION OF NET ASSET VALUE

The net asset value per Share of the Trust is determined no less frequently than weekly, generally on the last day of the week 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 Trust's net asset value per Share is determined by IBT, in the manner authorized by the Trustees of the Trust. Net asset value is computed by dividing the value of the Trust's total assets, less its liabilities by the number of shares outstanding.

Because Senior Loans are not currently actively traded in a public market, the Adviser, following procedures established by the Trust's Trustees, will value the Senior Loans held by the Trust at fair value. In valuing a Senior Loan, Eaton Vance will consider relevant factors, data, and information, including: (i) the characteristics of and fundamental analytical data relating to the Senior Loan, including the cost, size, current interest rate, period until next interest rate reset, maturity and base lending rate of the Senior Loan, the terms and conditions of the Loan and any related agreements, and the position of the Loan in the Borrower's debt structure; (ii) the nature, adequacy and value of the collateral, including the Trust's rights, remedies and

B-9

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 Senior Loan, including price quotations (if considered reliable) for and trading in the Senior Loan and interests in similar Loans and the market environment and investor attitudes towards the Senior Loan and interests in similar Senior Loans; (v) the reputation and financial condition of the Agent and any intermediate participants in the Senior Loan; and (vi) general economic and market conditions affecting the fair value of the loan interest. The Trustees will monitor the market liquidity of Senior Loans and may require use of a pricing service or mark-to-market procedures for some or all of such holdings in the future.

Non-loan holdings (other than short term obligations, but including listed issues) may be valued on the basis of prices furnished by one or more pricing services which determine prices for normal, institutional-size trading units of such securities using market information, transactions for comparable securities and various relationships between securities which are generally recognized by institutional traders. In certain circumstances, portfolio securities will be valued at the last sale price on the exchange that is the primary market for such securities, or the average of the last quoted bid price and asked price for those securities for which the over-the- counter market is the primary market or for listed securities in which there were no sales during the day. The value of interest rate swaps will be determined in accordance with a discounted present value formula and then confirmed by obtaining a bank quotation.

Short-term obligations which mature in 60 days or less are valued at amortized cost, if their original term to maturity when acquired by the Trust was 60 days or less, or are valued at amortized cost using their value on the 61st day prior to maturity, if their original term to maturity when acquired by the Trust was more than 60 days, unless in each case this is determined not to represent fair value. Repurchase agreements will be valued by the Trust at cost plus accrued interest. Securities for which there exist no price quotations or valuations and all other assets are valued at fair value as determined in good faith by or on behalf of the Trustees of the Trust.

PORTFOLIO TRADING

Specific decisions to purchase or sell securities for the Trust are made by employees of the Adviser who are appointed and supervised by its senior officers. Such employees may serve other clients of the Adviser in a similar capacity. Changes in the Trust's investments are reviewed by the Board.

The Trust will acquire Senior Loans from major international banks, selected domestic regional banks, insurance companies, finance companies and other financial institutions. In selecting financial institutions from which Senior Loans may be acquired, the Adviser will consider, among other factors, the financial strength, professional ability, level of service and research capability of the institution. While these financial institutions are generally not required to repurchase Senior Loans which they have sold, they may act as principal or on an agency basis in connection with their sale by the Trust.

Other fixed-income obligations which may be purchased and sold by the Trust are generally traded in the over-the-counter market on a net basis (i.e., without commission) through broker-dealers or banks acting for their own account rather than as brokers, or otherwise involve transactions directly with the issuers of such obligations. The Trust may also purchase fixed-income and other securities from underwriters, the cost of which may include undisclosed fees and concessions to the underwriters. While it is anticipated that the Trust will not pay significant brokerage commissions, on occasion it may be necessary or desirable to purchase or sell a security through a broker on an agency basis, in which case the Trust will incur a brokerage commission. Although spreads or commissions on portfolio transactions will, in the judgment of the Adviser, be reasonable in relation to the value of the services provided, spreads or commissions exceeding those which another firm might charge may be paid to firms who were selected to execute transactions on behalf of the Trust and the Adviser's other clients for providing brokerage and research services to the Adviser.

The frequency of portfolio purchases and sales, known as the "turnover rate," will vary from year to year, and is expected to be less than 100% per annum.

Securities considered as investments for the Trust 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 Trust and

B-10

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 Trust will not participate in a transaction that is allocated among other accounts. If an aggregated order cannot be filled completely, allocations will generally be made on a pro rata basis. An order may not be allocated on a pro rata basis where, for example: (i) consideration is given to portfolio managers who have been instrumental in developing or negotiating a particular investment; (ii) consideration is given to an account with specialized investment policies that coincide with the particulars of a specific investment; (iii) pro rata allocation would result in odd-lot or de minimis amounts being allocated to a portfolio or other client; or (iv) where the Adviser reasonably determines that departure from a pro rata allocation is advisable. While these aggregation and allocation policies could have a detrimental effect on the price or amount of the securities available to the Trust from time to time, it is the opinion of the Trustees of the Trust that the benefits from the Eaton Vance organization outweigh any disadvantage that may arise from exposure to simultaneous transactions.

TAXES

The following discussion is for general information purposes only. Prospective investors should consult their tax advisors regarding the specific federal income tax consequences of purchasing, holding and disposing of Shares, as well as the effects of state, local and foreign tax laws and any proposed tax law changes.

The Trust intends to qualify each year for treatment as a regulated investment company ("RIC"), under the Internal Revenue Code of 1986, as amended (the "Code"), in order to reduce or eliminate federal income tax. Accordingly, the Trust intends to satisfy certain requirements relating to sources of its income and diversification of its assets and to distribute a sufficient amount of its investment company taxable income so as to effect such qualification.

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

To avoid a non-deductible 4% federal excise tax, the Trust must distribute to its Shareholders by the end of each calendar year substantially all of its ordinary income and capital gain net income, plus certain other amounts. Under current law, provided that the Trust qualifies as a RIC, it should not be liable for any income, corporate excise or franchise tax in the Commonwealth of Massachusetts.

Income and gains from investments in securities of foreign issuers may be subject to foreign income, withholding or other taxes, which may reduce the Trust's yield and/or total return. Tax conventions between certain countries and the United States may reduce or eliminate these foreign taxes. Shareholders will not be able to claim any foreign tax credit or deduction with respect to these foreign taxes.

Certain investments of the Trust may bear original issue discount or market discount for tax purposes. The Trust will be required to include in income each year a portion of such original issue discount and may elect to include in income each year a portion of such market discount. In addition, the Trust may be required to include in income each year, for federal income tax purposes, income with respect to these or other investments even though the collectibility by the Trust of cash payments corresponding to such income is doubtful. The Trust may have to dispose of investments that it would otherwise have continued to hold to provide cash to enable it to satisfy its distribution requirements with respect to such income.

Some of the Trust's investment practices (including those involving certain risk management transactions) may be subject to special provisions of the Code that, among other things, may defer the Trust's deduction of certain losses and affect the holding period of certain securities it holds and the character of certain gains or losses it realizes. These provisions may also require the Trust to recognize income or gain without receiving cash with which to make distributions in the amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. The Trust will monitor its transactions and may make certain tax elections to mitigate the effect of these rules and prevent its disqualification as a RIC.

B-11

OTHER INFORMATION

The Trust 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 Trust property or the acts, obligations or affairs of the Trust. The Declaration of Trust also provides for indemnification out of the Trust 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 Trust itself is unable to meet its obligations. The Trust believes the risk of any Shareholder incurring any liability for the obligations of the Trust 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 Trust or its shareholders 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. 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 Trust's custodian or by votes cast at a meeting called for that purpose. The Declaration of Trust further provides that the Trustees of the Trust 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 so to do by the record holders of not less than 10 per centum of the outstanding shares.

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

NOTE TO FINANCIAL STATEMENT

Eaton Vance Senior Income Trust was formed under a Declaration of Trust dated September 23, 1998 and has been inactive since that date except for matters relating to its organization and registration as an investment company under the Investment Company Act of 1940 and the sale of 10,000 shares of its beneficial interest to Eaton Vance Management, the Fund's administrator. The deferred organization expenses are estimated to amount to $110,000. These expenses will be deferred and amortized over the period from the commencement of operations to June 30, 1999. The initial offering expenses, including federal and state registration and qualification fees, will be deducted from net proceeds, and will not exceed $0.02 per share, as Eaton Vance Management or an affiliate will pay any such expenses in excess of $0.02 per share. The initial offering expenses reflected above assume the initial sale of 20,000,000 shares. The amount paid by the Fund on any repurchase during the amortization period of any of the initial 10,000 common shares will be reduced by a pro rata portion of any unamortized organization expenses. Such proration is to be calculated by dividing the number of initial shares repurchased by the number of initial shares outstanding at the time of purchase.

B-14

APPENDIX A

RATINGS OF CORPORATE BONDS

DESCRIPTION OF CORPORATE BOND RATINGS OF STANDARD & POOR'S RATING GROUP:

AAA -- Bonds rated AAA have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

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

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

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

BB -- Bonds rated BB have less near-term vulnerability to default than other speculative grade debt. However, they face major ongoing uncertainties or exposure to adverse business, financial or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments.

B -- Bonds rated B have a greater vulnerability to default but presently have the capacity to meeting interest payments and principal repayments. Adverse business, financial or economic conditions would likely impair capacity or willingness to pay interest and repay principal.

CCC -- Bonds rated CCC have a current identifiable vulnerability to default and are dependent upon favorable business, financial and economic conditions to meet timely payments of interest and repayment of principal. In the event of adverse business, financial or economic conditions, they are not likely to have the capacity to pay interest and repay principal.

CC -- The rating CC is typically applied to debt subordinated to senior debt which is assigned an actual or implied CCC rating.

C -- The rating C is typically applied to debt subordinated to senior debt which is assigned an actual or implied CCC -- debt rating.

D -- Bonds rated D are in default, and payment of interest and/or repayment of principal is in arrears.

S&P's letter ratings may be modified by the addition of a plus (+) or a minus (-) sign designation, which is used to show relative standing within the major rating categories, except in the AAA (Prime Grade) category.

DESCRIPTION OF BOND RATINGS OF MOODY'S INVESTORS SERVICE, INC.

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

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

B-15

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

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

Ba -- Bonds which are rated Ba are judged to have speculative elements; their future cannot be considered as well assured. Often the protection of interest and principal payments may be very moderate and, therefore, not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B -- Bonds which are rated B generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

Caa -- Bonds which are rated Caa are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

Ca -- Bonds which are rated Ca present obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C -- Bonds which are rated C are the lowest rated class of bonds, and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

Moody's applies the numerical modifiers 1, 2 and 3 to show relative standing within the major rating categories, except in the Aaa category and in the categories below B. The modifier 1 indicates a ranking for the security in the higher end of a rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of a rating category.

ITEM 29. INDEMNIFICATION
The Registrant's By-Laws filed herewith and the Underwriting Agreement to be filed 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 capacities as such.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to trustees, officers and controlling persons of the Registrant and the Adviser and any underwriter to the foregoing provisions 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 such 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 trustee, officer, or controlling person or the Registrant and the Underwriters in connection with the successful defense of any action, suit or proceeding) is asserted against the

C-2

Registrant by such trustee, officer or controlling person or the Distributor in connection with the Common Shares 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 such Act and will be governed by the final adjudication of such issue.

ITEM 30. BUSINESS AND OTHER CONNECTIONS OF THE 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. 1-8100); 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, Boston, MA 02116, and its transfer agent, First Data Investor Services Group, 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, 24 Federal Street, Boston, MA 02110. Registrant is informed that all applicable accounts, books and documents required to be maintained by registered investment advisers are in the custody and possession of Eaton Vance Management.

ITEM 32. MANAGEMENT SERVICES
None.

ITEM 33. UNDERTAKINGS

(1) Registrant undertakes to suspend offering of its Common Shares until it amends its prospectus if (a) subsequent to the effective date of its Registration Statement, the net asset value declines more than 10 percent from its net asset value as of the effective date of the Registration Statement, or (b) the net asset value increases to an amount greater than its net proceeds as stated in the prospectus.

(2) Not applicable

(3) Not applicable

(4) Not applicable

(5) (a) For purpose of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of a registration statement in reliance upon Rule 430A and contained in the form of prospectus filed by the Registrant pursuant to Rule 497(h) under the Securities Act of 1933, shall be deemed to be part of this Registration Statement as of the time it was declared effective.

(b) For the purpose of determining any liability under the Securities Act of 1933, 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 initial bona fide offering thereof.

(6) The registrant undertakes to send by first class mail or other means designed to ensure equally prompt delivery, within two business days of receipt of a written or oral request, its Statement of Additional Information.

C-3

Powers and Duties of Trustees and Officers

SECTION 1. TRUSTEES. The business and affairs of the Trust shall be managed by the Trustees, and they shall have all powers necessary and desirable to carry out that responsibility, so far as such powers are not inconsistent with the laws of the Commonwealth of Massachusetts, the Declaration of Trust, or these By-Laws.


SECTION 2. EXECUTIVE AND OTHER COMMITTEES. The Trustees may elect from their own number an executive committee to consist of not less than three nor more than five members, which shall have the power and duty to conduct the current and ordinary business of the Trust while the Trustees are not in session, and such other powers and duties as the Trustees may from time to time delegate to such committee. The Trustees may also elect from their own number other committees from time to time, the number composing such committees and the powers conferred upon the same to be determined by the Trustees. Without limiting the generality of the foregoing, the Trustees may appoint a committee consisting of less than the whole number of Trustees then in office, which committee may be empowered to act for and bind the Trustees and the Trust, as if the acts of such committee were the acts of all the Trustees then in office, with respect to the institution, prosecution, dismissal, settlement, review, investigation or other disposition of any dispute, claim, action, suit or proceeding which shall be pending or threatened to be brought before any court, administrative agency or other adjudicatory body.

SECTION 3. CHAIRMAN OF THE TRUSTEES. The Trustees may, but need not, appoint from among their number a Chairman. When present he shall preside at the meetings of the shareholders and of the Trustees. He may call meetings of the Trustees and of any committee thereof whenever he deems it necessary. He shall be an executive officer of this Trust and shall have, with the President, general supervision over the business and policies of this Trust, subject to the limitations imposed upon the President, as provided in Section 4 of this Article III.

SECTION 4. PRESIDENT. In the absence of the Chairman of the Trustees, the President shall preside at all meetings of the shareholders. Subject to the Trustees and to any committees of the Trustees, within their respective spheres, as provided by the Trustees, he shall at all times exercise a general supervision and direction over the affairs of the Trust. He shall have the power to employ attorneys and counsel for the Trust and to employ such subordinate officers, agents, clerks and employees as he may find necessary to transact the business of the Trust. He shall also have the power to grant, issue, execute or sign such powers of attorney, proxies or other documents as may be deemed advisable or necessary in furtherance of the interests of the Trust. The President shall have such other powers and duties as, from time to time, may be conferred upon or assigned to him by the Trustees.

SECTION 5. TREASURER. The Treasurer shall be the principal financial and accounting officer of the Trust. He shall deliver all funds and securities of the Trust which may come into his hands to such bank or trust company as the Trustees shall employ as custodian in accordance with Article III of the Declaration of Trust.

The Treasurer shall perform such duties additional to foregoing as the Trustees may from time to time designate.

SECTION 6. SECRETARY. The Secretary shall record in books kept for the purpose all votes and proceedings of the Trustees and the shareholders at their respective meetings.

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 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 mailing the same postage paid, addressed to him at his address as it appears upon the books of the Trust, at least ten (10) days no more than ninety (90) 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 post office 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. Shared 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

3

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.

SECTION 5. VOTING. At each meeting of the shareholders every shareholder of the Trust shall be entitled to one (1) 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. A proxy may be in writing subscribed by the shareholder or by his duly authorized representatives, agent or attorney. A written proxy shall be dated; if an undated written proxy solicited by the management of the Trust is delivered to the Trust or its agent or representative, such proxy shall be deemed dated by the shareholder on the date of its receipt by the Trust or its agent or representative. A written proxy need not be sealed, witnessed or acknowledged. A written proxy may be delivered to the Trust or its agent by facsimile machine, graphic communication equipment or similar electronic transmission. The shareholder may also authorize and empower the persons named as proxies, representatives, agents or attorneys (or their duly appointed substitutes), or any one of them on any form of proxy solicited by the management of the Trust to vote all shares of the Trust which he is entitled to vote upon any matter at any meeting of the shareholders by recording his voting instructions on any recording device maintained for the purpose by the Trust or its agent or representative; such recorded instructions shall be deemed to constitute a written proxy subscribed by the shareholder and delivered by him to the Trust or its agent or representative and shall be deemed to be dated as of the date such instructions were transmitted, and the shareholder shall be deemed to have approved and ratified all actions taken by such persons in accordance with the voting instructions so recorded. No proxy which is dated (or deemed dated) more than six months before the initial session of the meeting shall be accepted and no such proxy shall be valid after the final adjournment of the meeting. A proxy solicited by the management of the Trust purporting to be executed or transmitted by or on behalf of a shareholder shall be valid unless challenged at or prior to exercise of the proxy, and the

4

burden of proving any invalidity shall be borne by the person asserting the challenge. A proxy solicited by the management of the Trust with respect to shares held in the name of two or more persons shall be valid if executed or transmitted by one of them unless at or prior to its exercise the Trust receives a specific written notice to the contrary from any one of them.

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.

ARTICLE V

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 (2) 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 (1) 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

5

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 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 (75) 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

6

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

Fiscal Year

The fiscal year of the Trust shall end on June 30 of each year, provided, however, that the Trustees may from time to time change the fiscal year.

ARTICLE VIII

Seal

The Trustees may adopt a seal of the Trust which shall be in such form and shall have such inscription thereon as the Trustees may from time to time prescribe.

ARTICLE IX

Inspection of Books

The Trustees shall from time to time determine whether and to what extent, and at what times and places, and under what conditions and regulations the accounts and books of the Trust or any of them shall be open to the inspection of the shareholders; and no shareholder shall have any right to inspect any account or book or document of the Trust except as conferred by law or authorized by the Trustees or by resolution of the shareholders.

7

ARTICLE X

Principal Custodian and Sub-custodians

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

8

doing business in Boston, Massachusetts, of its own selection, having an aggregate capital, surplus and undivided profits, as 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.

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.

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,

9

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

(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

10

(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 Securities and Exchange Commission), or (ii) involved in the claim, action, suit or proceeding.

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

The Trustees shall at least semi-annually submit 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

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.

Exhibit (e)

EATON VANCE SENIOR INCOME TRUST
TERMS AND CONDITIONS OF DIVIDEND REINVESTMENT PLAN

Holders of common shares (the "Shares") of Eaton Vance Senior Income Trust (the "Fund") participating (the "Participants") in its Dividend Reinvestment Plan (the "Plan") are advised as follows:

1. THE PLAN AGENT. First Data Investor Services Group (the "Agent") will act as Agent for each Participant. The Agent will open an account for each Participant under the Plan in the same name as his or her outstanding Shares are registered.

2. CASH OPTION. The Fund will declare its income dividends and capital gains distributions ("Distributions") payable in Shares, or, at the option of Shareholders, in cash. Therefore, each Participant that does not choose cash distributions will receive Shares.

3. MARKET PREMIUM ISSUANCES. If on the payment date for a Distribution, the net asset value per Share is equal to or less than the market price per Share plus estimated brokerage commissions, the Agent shall receive newly issued Shares, including fractions, from the Fund for each Participant's account. The number of additional shares to be credited shall be determined by dividing the dollar amount of the Distribution by the greater of the net asset value per Share on the payment date or 95% of the then current market price per Share on the payment date.

4. MARKET DISCOUNT PURCHASES. If the net asset value per Share exceeds the market price plus estimated brokerage commissions on the payment date for a Distribution, the Agent (or a broker-dealer selected by the Agent) shall endeavor, for a purchase period of 30 days to apply the amount of such Distribution on each Participant's Shares (less their PRO RATA share of brokerage commissions incurred) to purchase Shares on the open market. The average price (including brokerage commissions) of all Shares purchased by the Agent as Agent shall be the price per Share allocable to each Participant. If, at the close of business on any day during the purchase period on which net asset value per Share is calculated such net asset value equals or is less than the market price per Share plus estimated brokerage commissions, the Agent will cease open-market purchases, and the uninvested portion of such Distribution shall be filled through the issuance of new Shares from the Fund at the price set forth in paragraph 3 above. Open-market purchases may be made on any securities exchange where Shares are traded, in the over-the-counter market or in negotiated transactions and may be on such terms as to price, delivery and otherwise as the Agent shall determine.


5. VALUATION. The market price of Shares on a particular date shall be the last sales price on the New York Stock Exchange on that date, or, if there is no sale on such Exchange on that date, then the mean between the closing bid and asked quotations on such Exchange on such date. The net asset value per Share on a particular date shall be the amount most recently calculated by or on behalf of the Fund as required by law.

6. LIABILITY OF AGENT. The Agent shall at all times act in good faith and agree to use its best efforts within reasonable limits to ensure the accuracy of all services performed under this Agreement and to comply with applicable law, but assumes no responsibility and shall not be liable for loss or damage due to errors unless such error is caused by the Agent's negligence, bad faith, or willful misconduct or that of its employees. Each Participant's uninvested funds held by the Agent will not bear interest. The Agent shall have no liability in connection with any inability to purchase Shares within the time provided, or with the timing of any purchases effected. The Agent shall have no responsibility for the value of Shares acquired. For the purpose of cash investments, the Agent may commingle Participants' funds.

7. RECORDKEEPING. The Agent may hold each Participant's Shares acquired pursuant to the Plan together with the Shares of other shareholders of the Fund acquired pursuant to the Plan in noncertificated form in the Agent's name or that of the Agent's nominee. Upon a Participant's written request, the Agent will deliver to the Participant, without charge, a certificate or certificates for the full shares. Each Participant will be sent a confirmation by the Agent of each acquisition made for their account as soon as practicable but not later than 60 days after the date thereof. Although each Participant may from time to time have an undivided fractional interest (computed to three decimal places) in a share of the Fund, no certificates for a fractional share will be issued. Distributions on fractional shares will be credited to each Participant's account. In the event of termination of a Participant's account under the Plan, the Agent will adjust for any such undivided fractional interest in cash at the market value of Shares at the time of termination.

Any share dividends or split shares distributed by the Fund on Shares held by the Agent for Participants will be credited to their accounts. In the event that the Fund makes available to its shareholders rights to purchase additional shares of other securities, the Shares held for each Participant under the Plan will be added to other shares held by the Participant in calculating the number of rights to be issued to each Participant.

8. PROXY MATERIALS. The Agent will forward to each Participant any proxy solicitation material; and will vote any shares so held for each Participant first in accordance with the instructions set forth on proxies returned by the Participant to the Fund, and then with respect to any proxies not returned by the Participant to the Fund in the same portion as the agent votes proxies returned by the Participants to the Fund.

2

9. FEES. The Agent's service fee for handling Distributions will be paid by the Fund. Each Participant will be charged their PRO RATA share of brokerage commissions on all open-market purchases. If a Participant elects by written notice to the Agent to have the Agent sell part or all of his or her Shares and remit the proceeds, the Agent is authorized to deduct a $5.00 fee plus brokerage commissions from the proceeds.

10. TERMINATION IN THE PLAN. Each registered Participant may terminate his or her account under the Plan by notifying the Agent in writing at P.O. Box 8030, Boston, MA 02266-8030, or by telephone at 800-331-1710. Such termination will be effective with respect to a Distribution if the Participant's notice is received by the Agent at least ten days prior to the Distribution record date. The Plan may be terminated by the Agent or the Fund upon notice in writing mailed to each Participant at least 90 days prior to any record date for the payment of any Distribution. Upon any termination, the Agent will cause a certificate or certificates to be issued for the full shares held for each Participant under the Plan and cash adjustment for any fraction to be delivered to them without charge.

11. AMENDMENT OF THE PLAN. These terms and conditions may be amended by the Agent or the Fund at any time or times but, except when necessary or appropriate to comply with applicable law or the rules or policies of the Securities and Exchange Commission or any other regulatory authority, only by mailing to each Participant appropriate written notice at least 30 days prior to the effective date thereof. The amendment shall be deemed to be accepted by each Participant unless, prior to the effective date thereof, the Agent receives written notice of the termination of their account under the Plan. Any such amendment may include an appointment by the Agent of a successor Agent.

12. APPLICABLE LAW. These terms and conditions shall be governed by the laws of the Commonwealth of Massachusetts.

Exhibit (g)

EATON VANCE SENIOR INCOME TRUST

INVESTMENT ADVISORY AGREEMENT

AGREEMENT made this 19th day of October, 1998, between Eaton Vance Senior Income Trust, a Massachusetts business trust (the "Trust"), and Eaton Vance Management, a Massachusetts business trust (the "Adviser").

1. DUTIES OF THE ADVISER. The Trust hereby employs the Adviser to act as investment adviser for and to manage the investment and reinvestment of the assets of the Trust and to administer its affairs, subject to the supervision of the Trustees of the Trust, for the period and on the terms set forth in this Agreement.

The Adviser hereby accepts such employment, and undertakes to afford to the Trust the advice and assistance of the Adviser's organization in the choice of investments and in the purchase and sale of interests in Senior Loans (as defined in the Trust's registration statement) and other permitted investments for the Trust and to furnish for the use of the Trust office space and all necessary office facilities, equipment and personnel for servicing the investments of the Trust and to pay the salaries and fees of all officers and Trustees of the Trust who are members of the Adviser's organization and all personnel of the Adviser performing services relating to research and investment activities. The Adviser shall for all purposes herein be deemed to be an independent contractor and shall, except as otherwise expressly provided or authorized, have no authority to act for or represent the Trust in any way or otherwise be deemed an agent of the Trust.

The Adviser shall provide the Trust with such investment management and supervision as the Trust may from time to time consider necessary for the proper supervision of the Trust. As investment adviser to the Trust, the Adviser shall furnish continuously an investment program and shall determine from time to time what interests in Senior Loans and other securities shall be acquired, disposed of or exchanged and what portion of the Trust's assets shall be held uninvested, subject always to the applicable restrictions of the Declaration of Trust, By-Laws and registration statement of the Trust. The Adviser is authorized, in its discretion and without prior consultation with the Trust, to buy, sell, lend and otherwise trade in any Senior Loans, stocks, bonds, debt instruments, options and other securities and investment instruments on behalf of the Trust, to purchase, write or sell derivative instruments on behalf of the Trust, and to execute any and all agreements and instruments and to do any and all things incidental thereto in connection with the investment management of the Trust. Should the Trustees of the Trust at any time, however, make any specific determination as to investment policy for the Trust and notify the Adviser thereof in writing, the Adviser shall be bound by such determination for the period, if any, specified in such notice or until similarly notified that such determination has been revoked. The Adviser shall take, on behalf of the Trust, all actions which it deems necessary or desirable to implement the investment policies of the Trust.

The Adviser shall place all orders for the purchase or sale of portfolio securities for the account of the Trust either directly with the issuer or with brokers or dealers or banks selected by the Adviser, or directly with a co-lender or other participant in Senior Loans (as defined in the Trust's


registration statement), and to that end the Adviser is authorized as the agent of the Trust to give instructions to the custodian of the Trust as to deliveries of securities and payments of cash for the account of the Trust. In connection with the selection of such brokers or dealers or banks and the placing of such orders, the Adviser shall use its best efforts to seek to execute portfolio security transactions at prices which are advantageous to the Trust and (when a disclosed commission is being charged) at reasonably competitive commission rates. In selecting brokers or dealers qualified to execute a particular transaction, brokers or dealers may be selected who also provide brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934) to the Adviser and the Adviser is expressly authorized to cause the Trust to pay any broker or dealer who provides such brokerage and research services a commission for executing a security transaction 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 amount of commission is reasonable in relation to the value of the brokerage and research services provided by such broker or dealer, viewed in terms of either that particular transaction or the overall responsibilities which the Adviser and its affiliates have with respect to accounts over which they exercise investment discretion. Subject to the requirement set forth in the second sentence of this paragraph, the Adviser is authorized to consider, as a factor in the selection of any broker or dealer with whom purchase or sale orders may be placed, the fact that such broker or dealer has sold or is selling shares of any one or more investment companies sponsored by the Adviser or its affiliates.

The Adviser shall not be responsible for providing certain special administrative services to the Trust under this Agreement. Eaton Vance Management, in its capacity as Administrator of the Trust, shall be responsible for providing such services to the Trust under the Trust's separate Administration Agreement.

2. COMPENSATION OF THE ADVISER. For the services, payments and facilities to be furnished hereunder by the Adviser, the Adviser shall be entitled to receive from the Trust compensation in an amount equal to 17/240 of 1% (equivalent to .85% annually) of average weekly gross assets of the Trust throughout each month. (Gross assets shall be calculated by deducting accrued liabilities of the Trust except the principal amount of any indebtedness for money borrowed, including debt securities issued by the Trust. Accrued liabilities are expenses incurred in the normal course of operations.)

Such compensation shall be paid monthly in arrears on the last business day of each month. The Trust's net assets shall be computed in accordance with the Declaration of Trust of the Trust and any applicable votes and determinations of the Trustees of the Trust.

In case of initiation or termination of the Agreement during any month, the fee for that month shall be reduced proportionately on the basis of the number of calendar days during which the Agreement is in effect and the fee shall be computed upon the basis of the average gross assets for the business days the Agreement is so in effect for that month.

The Adviser may, from time to time, waive all or a part of the above compensation.

3. ALLOCATION OF CHARGES AND EXPENSES. It is understood that the Trust will pay all expenses other than those expressly stated to be payable by the Adviser hereunder, which expenses payable by the Trust shall include, without implied limitation, (i) expenses of maintaining the Trust and continuing its

-2-

existence, (ii) registration of the Trust under the Investment Company Act of 1940, (iii) commissions, spreads, fees and other expenses connected with the acquisition, holding and disposition of securities and other investments, (iv) auditing, accounting and legal expenses, (v) taxes and interest, (vi) governmental fees, (vii) expenses of listing shares of the Trust with a stock exchange, and expenses of issue, sale, repurchase and redemption (if any) of interests in the Trust, including expenses of conducting tender offers for the purpose of repurchasing Trust interests, (viii) expenses of registering and qualifying the Trust and its shares under federal and state securities laws and of preparing and filing registration statements and amendments for such purposes
(ix) expenses of reports and notices to shareholders and of meetings of shareholders and proxy solicitations therefor, (x) expenses of reports to governmental officers and commissions, (xi) insurance expenses, (xii) association membership dues, (xiii) fees, expenses and disbursements of custodians and subcustodians for all services to the Trust (including without limitation safekeeping of funds, securities and other investments, keeping of books, accounts and records, and determination of net asset values), (xiv) fees, expenses and disbursements of transfer agents, dividend disbursing agents, shareholder servicing agents and registrars for all services to the Trust, (xv) expenses for servicing shareholder accounts, (xvi) any direct charges to shareholders approved by the Trustees of the Trust, (xvii) compensation and expenses of Trustees of the Trust who are not members of the Adviser's organization, (xviii) pricing and valuation services employed by the Trust, and
(xix) such non-recurring items as may arise, including expenses incurred in connection with litigation, proceedings and claims and the obligation of the Trust to indemnify its Trustees, officers and shareholders with respect thereto.

4. OTHER INTERESTS. It is understood that Trustees and officers of the Trust and shareholders of the Trust are or may be or become interested in the Adviser as trustees, officers, employees, shareholders or otherwise and that trustees, officers and shareholders of the Adviser are or may be or become similarly interested in the Trust, and that the Adviser may be or become interested in the Trust as Holder or otherwise. It is also understood that trustees, officers, employees and shareholders of the Adviser may be or become interested (as directors, trustees, officers, employees, shareholders or otherwise) in other companies or entities (including, without limitation, other investment companies) which the Adviser may organize, sponsor or acquire, or with which it may merge or consolidate, and which may include the words "Eaton Vance" or any combination thereof as part of their name, and that the Adviser or its subsidiaries or affiliates may enter into advisory or management agreements or other contracts or relationships with such other companies or entities.

5. LIMITATION OF LIABILITY OF THE ADVISER. The services of the Adviser to the Trust are not to be deemed to be exclusive, the Adviser being free to render services to others and engage in other business activities. In the absence of willful misfeasance, bad faith, gross negligence or reckless disregard of obligations or duties hereunder on the part of the Adviser, the Adviser shall not be subject to liability to the Trust or to any shareholder the Trust for any act or omission in the course of, or connected with, rendering services hereunder or for any losses which may be sustained in the acquisition, holding or disposition of any interest in a Loan or of any security, investment or other asset.

6. SUB-INVESTMENT ADVISERS. The Adviser may employ one or more sub-investment advisers from time to time to perform such of the acts and services of the Adviser, including the selection of brokers or dealers to execute the Trust's portfolio security transactions, and upon such terms and conditions as may be agreed upon between the Adviser and such sub-investment adviser and approved by the Trustees of the Trust, all as permitted by the Investment Company Act of 1940.

-3-

7. DURATION AND TERMINATION OF THIS AGREEMENT. This Agreement shall become effective upon the date of its execution, and, unless terminated as herein provided, shall remain in full force and effect through and including February 28, 2000 and shall continue in full force and effect indefinitely thereafter, but only so long as such continuance after February 28, 2000 is specifically approved at least annually (i) by the Board of Trustees of the Trust or by vote of a majority of the outstanding voting securities of the Trust and (ii) by the vote of a majority of those Trustees of the Trust who are not interested persons of the Adviser or the Trust cast in person at a meeting called for the purpose of voting on such approval.

Either party hereto may, at any time on sixty (60) days' prior written notice to the other, terminate this Agreement without the payment of any penalty, by action of Trustees of the Trust or the trustees of the Adviser, as the case may be, and the Trust may, at any time upon such written notice to the Adviser, terminate this Agreement by vote of a majority of the outstanding voting securities of the Trust. This Agreement shall terminate automatically in the event of its assignment.

8. AMENDMENTS OF THE AGREEMENT. This Agreement may be amended by a writing signed by both parties hereto, provided that no amendment to this Agreement shall be effective until approved (i) by the vote of a majority of those Trustees of the Trust who are not interested persons of the Adviser or the Trust cast in person at a meeting called for the purpose of voting on such approval, and (ii) by vote of a majority of the outstanding voting securities of the Trust.

9. LIMITATION OF LIABILITY. The Adviser expressly acknowledges the provision in the Declaration of Trust of the Trust limiting the personal liability of the Trustees, officers and shareholders of the Trust, and the Adviser hereby agrees that it shall have recourse to the Trust for payment of claims or obligations as between the Trust and the Adviser arising out of this Agreement and shall not seek satisfaction from any Trustee, officer or shareholders of the Trust.

10. USE OF THE NAME "EATON VANCE". The Adviser hereby consents to the use by the Trust of the name "Eaton Vance" as part of the Trust's name; provided, however, that such consent shall be conditioned upon the employment of the Adviser or one of its affiliates as the investment adviser of the Trust. The name "Eaton Vance" or any variation thereof may be used from time to time in other connections and for other purposes by the Adviser and its affiliates and other investment companies that have obtained consent to the use of the name "Eaton Vance". The Adviser shall have the right to require the Trust to cease using the name "Eaton Vance" as part of the Trust's name if the Trust ceases, for any reason, to employ the Adviser or one of its affiliates as the Trust's investment adviser. Future names adopted by the Trust for itself, insofar as such names include identifying words requiring the consent of the Adviser, shall be the property of the Adviser and shall be subject to the same terms and conditions.

11. CERTAIN DEFINITIONS. The terms "assignment" and "interested persons" when used herein shall have the respective meanings specified in the Investment Company Act of 1940 as now in effect or as hereafter amended subject, however, to such exemptions as may be granted by the Securities and Exchange Commission by any rule, regulation or order. The term "vote of a majority of the outstanding voting securities" shall mean the vote, at a meeting of shareholders, of the lesser of (a) 67 per centum or more of the shares of the Trust present or represented by proxy at the meeting if the Holders of more than 50 per centum of the shares of the Trust are present or represented by proxy at the meeting, or (b) more than 50 per centum of the shares of the Trust.

Ladies and Gentlemen:

Eaton Vance Senior Income Trust, a Massachusetts business trust (the "Trust"), proposes to issue and sell to you and the other underwriters named in Schedule 1 hereto (the "Underwriters"), for whom you are acting as representatives (the "Representatives"), up to [6,000,000] shares of beneficial interest (the "Firm Shares"), par value $.01 per share (the "Shares of Beneficial Interest"). In addition, the Trust


* Plus an option to purchase, in the aggregate, up to [900,000] additional Shares to cover over-allotments.

hereby grants to the Underwriters an option (the "Option") to purchase up to an additional [900,000] of its Shares (the "Option Shares") solely for the purpose of covering over-allotments. The Firm Shares and the Option Shares are referred to collectively herein as the "Shares."

Eaton Vance Management, a Massachusetts business trust ("Eaton Vance" or the "Investment Adviser"), will act as the Trust's investment adviser pursuant to an Investment Advisory Agreement by and between the Trust and the Investment Adviser, dated as of October 19, 1998 (the "Investment Advisory Agreement"). The Trust has engaged Eaton Vance to act as its administrator pursuant to an Administration Agreement, dated as of October 19, 1998. Investors Bank & Trust Company ("IBT") will act as the custodian (the "Custodian") of the Trust's cash and portfolio assets pursuant to a Custody Agreement, effective as of October 19, 1998 (the "Custody Agreement"). First Data Investor Services Group will act as the Trust's transfer agent and dividend disbursing agent (the "Transfer Agent") pursuant to a transfer agency agreement, dated as of October 19, 1998 (the "Transfer Agency Agreement").

The Trust and the Investment Adviser each hereby confirms as follows their agreements with the Representatives and the several other Underwriters.

1. SALE AND PURCHASE; COMPENSATION

(a) The Trust will issue and sell to each Underwriter, and each Underwriter will purchase from the Trust, the number of Firm Shares set forth opposite such Underwriter's name in Schedule 1 hereto, at the purchase price of $10.00 per Firm Share.

(b) The Trust grants to the Underwriters the Option to purchase all or any part of the Option Shares for the same consideration per share as for the Firm Shares. The Option may be exercised only to cover over-allotments in the sales of the Firm Shares by the Underwriters. The number of Option Shares (adjusted by the Representatives to eliminate fractions) to be purchased by each Underwriter will be the same percentage of the aggregate number of Option Shares being sold as such Underwriter is obligated to purchase of the Firm Shares. Such Option may be exercised in whole or in part, only to cover over-allotments, at any time or from time to time on or before the 45th day after the date of this Underwriting Agreement, upon written or telefacsimile notice (the "Option Shares Notice") from the Representatives to the Trust no later than 12:00 noon, New York City time, at least two and not more than five business days before the date specified for closing in the Option Shares Notice (the "Option Shares Closing Date"), setting forth the number of Option Shares to be

2

purchased and the time and date of such purchase. Upon delivery and receipt of the Option Shares Notice, the Trust will issue and sell to each Underwriter, and each Underwriter will purchase from the Trust, on the Option Shares Closing Date, its portion of the number of Option Shares set forth in the Option Shares Notice.

(c) The obligations of the Underwriters under this Underwriting Agreement are several and not joint and are undertaken on the basis of the representations and are subject to the conditions set forth in this Underwriting Agreement.

(d) The Investment Adviser agrees to make the payments to the Underwriters when and as required by Section 2 hereof.

2. PAYMENT AND DELIVERY. Delivery by the Trust of the Firm Shares (the "Firm Shares Closing") to the Representatives for the accounts of the Underwriters against payment of the purchase price by wire transfer of Federal Funds or similar same day funds to the Trust for the Firm Shares, will take place at the offices of PaineWebber Incorporated (the "Managing Representative"), 1285 Avenue of the Americas, New York, New York or such other location as is agreed upon by the parties hereto, or through the facilities of the Depository Trust Company or another mutually agreeable facility, at 9:00
a.m., New York City time, on the third business day following the date of this Underwriting Agreement, or at such time on such other date, not later than ten business days after the date of this Underwriting Agreement, as may be agreed upon by the Trust and the Managing Representative (the "Firm Shares Closing Date").

If and to the extent that the Option is exercised, delivery of the Option Shares and payment by the Underwriters (in the manner specified above) will take place at the offices or through the facilities specified above for the Firm Shares Closing at the time and date (which may be the Firm Shares Closing Date) specified in the Option Shares Notice. Any Option Shares Closing Date may not be later than three business days following the exercise of the related Option. The Firm Shares Closing Date and any Option Shares Closing Date are called the "Closing Dates."

Certificates evidencing Shares of Beneficial Interest will be in definitive form (or temporary form acceptable to the New York Stock Exchange), registered in such names and in such denominations as the Managing Representative requests at least three full business days before the Firm Shares Closing Date or, in the case of Option Shares, on the day of notice of exercise of the Option as described in Section 1(b), and will be made available to the Managing Representative for checking and packaging, at

3

a place in New York City designated by the Managing Representative, at least one full business day before the relevant Closing Date.

Simultaneous with delivery to the Underwriters of and payment by the Underwriters for (i) Firm Shares on the Firm Shares Closing Date and (ii) Option Shares on the Option Shares Closing Date, Eaton Vance (or an affiliate as determined by Eaton Vance) will pay to the Underwriters an amount equal to 4.50% of the purchase price per Share for each Share to be purchased by the Underwriters on such date by wire transfer of Federal Funds or similar same-day funds on such Firm Shares Closing Date or Option Shares Closing Date, as the case may be, to the order of the Managing Representative, on behalf of itself and the Underwriters.

3. REGISTRATION STATEMENT AND PROSPECTUS; PUBLIC OFFERING. The Trust has filed with the Securities and Exchange Commission (the "Commission"), pursuant to the Securities Act of 1933, as amended (the "Securities Act"), the Investment Company Act of 1940, as amended (the "Investment Company Act"), and the published rules and regulations adopted by the Commission under the Securities Act (the "Securities Act Rules") and the Investment Company Act (the "Investment Company Act Rules"), a Notification of Registration on Form N-8A (the "Notification") pursuant to Section 8 of the Investment Company Act and a registration statement on Form N-2 (File Nos. 333-64151 and 811-09013) relating to the Shares (the "registration statement"), including a preliminary prospectus (including any preliminary statement of additional information), and such amendments to such registration statement as may have been required to the date of this Underwriting Agreement. The preliminary prospectus (including any preliminary statement of additional information) is to be used in connection with the offering and sale of the Shares. The term "Preliminary Prospectus" as used herein means any preliminary prospectus (including any preliminary statement of additional information) included at any time as a part of the registration statement and any preliminary prospectus (including any preliminary statement of additional information) omitted therefrom pursuant to the Securities Act Rules.

The registration statement as amended at the time it becomes or became effective (the "Effective Date"), including financial statements and all exhibits, and any information deemed to be included by Rule 430A, is called the "Registration Statement." The term "Prospectus" means the prospectus (including any statement of additional information) in the form in which it is first filed with the Commission pursuant to Rule 497(b), (h) or (j) of the Securities Act Rules, as the case may be.

The Trust and the Investment Adviser understand that the Underwriters propose to make a public offering of the Firm Shares, as described in the Prospectus, as soon after the Effective Date (or, if later, after the date this Underwriting Agreement is signed) as the Managing Representative deems advisable. The Trust confirms that the Underwriters and dealers have been authorized to distribute the Preliminary Prospectus relating to the Shares included in the initial filing of the registration statement and are authorized to distribute the Prospectus and any amendments or supplements thereto.

5. AGREEMENTS OF THE PARTIES.

(a) If the registration statement relating to the Shares has not yet become effective, the Trust will promptly file the Final Amendment, if not previously filed, with the Commission, and will use its best efforts to cause such registration statement to become effective and, as soon as the Trust is advised, will advise the Representative when the Registration Statement or any amendment thereto has become effective. If the Registration Statement has become effective and the Prospectus contained therein omits certain information at the time of effectiveness pursuant to Rule 430A of the Securities Act Rules, the Trust will file a 430A Prospectus pursuant to Rule 497(h) of the Securities Act Rules as promptly as practicable, but no later than the second business day following the earlier of the date of the determination of the offering price of the Shares or the date the Prospectus is first used after the Effective Date. If the Registration Statement has become effective and the Prospectus contained therein does not so omit such information, the Trust will file a Prospectus pursuant to Rule 497(b) or (j) of the Securities Act Rules as promptly as practicable, but no later than the fifth business day following the date of the later of the Effective Date or the commencement of the public offering of the Shares after the Effective Date. In either case, the Trust will provide the Representatives satisfactory evidence of the filing. The Trust will not file with the Commission any Prospectus or any other amendment (except any post-effective amendment which is filed with the Commission after the later of
(x) one year from the date of this Underwriting Agreement or (y) the date on which distribution of the Shares is completed) or supplement to the Registration Statement or the Prospectus unless a copy has first been submitted to the Managing Representative a reasonable time before its filing and the Managing Representative has not objected to it in writing within a reasonable time after receiving the copy.

(b) For the period of three years from the date hereof, the Trust will advise the Representatives promptly (1) of the issuance by the Commission of any order in respect of the Trust or the Investment Adviser which relates to the Trust, or which relates to any material arrangements or proposed material arrangements involving the Trust or the Investment Adviser, (2) of the initiation or threatening of any proceedings for, or receipt by the Trust of any notice with respect to, the suspension of the qualification of the Shares for sale in any jurisdiction or the issuance of any order

14

by the Commission suspending the effectiveness of the Registration Statement,
(3) of receipt by the Trust, or any representative or attorney of the Trust, of any other communication from the Commission relating in any material way to the Trust, the Registration Statement, the Notification, any Preliminary Prospectus, the Prospectus or to the transactions contemplated by this Underwriting Agreement and (4) the issuance by any court, regulatory body, administrative agency or other governmental agency or body, whether foreign or domestic, of any order, ruling or decree, or the threat to initiate any proceedings with respect thereto, regarding the Trust, which relates in any material way to the Trust or any material arrangements or proposed material arrangements involving the Trust. The Trust will make every reasonable effort to prevent the issuance of any order suspending the effectiveness of the Registration Statement and, if any such order is issued, to obtain its lifting as soon as possible.

(c) If not delivered prior to the date of this Underwriting Agreement, the Trust will deliver to the Representatives, without charge, a signed copy of the registration statement and the Notification and of any amendments (except any post-effective amendment which is filed with the Commission after the later of (x) one year from the date of this Underwriting Agreement or (y) the date on which the distribution of the Shares is completed) to either the Registration Statement or the Notification (including all exhibits filed with any such document) and as many conformed copies of the registration statement and any amendments thereto (except any post-effective amendment which is filed with the Commission after the later of (x) one year from the date of this Underwriting Agreement or (y) the date on which the distribution of the Shares is completed) (excluding exhibits) as the Representatives may reasonably request.

(d) During such period as a prospectus is required by law to be delivered by an underwriter or a dealer, the Trust will deliver, without charge, to the Representatives, the Underwriters and any dealers, at such office or offices as the Representatives may designate, as many copies of the Prospectus as the Representatives may reasonably request, and, if any event occurs during such period as a result of which it is necessary to amend or supplement the Prospectus, in order to make the statements therein, in light of the circumstances existing when such Prospectus is delivered to a purchaser of Shares, not misleading in any material respect, or if during such period it is necessary to amend or supplement the Prospectus to comply with the Securities Act, the Investment Company Act, the Securities Act Rules or the Investment Company Act Rules, the Trust promptly will prepare, submit to the Managing Representative, file with the Commission and deliver, without charge, to the Underwriters and to dealers (whose names and addresses the Representatives will furnish to the Trust) to whom Shares may have been sold by the Underwriters, and to other dealers on request, amendments or

15

supplements to the Prospectus so that the statements in such Prospectus, as so amended or supplemented, will not, in light of the circumstances existing when such Prospectus is delivered to a purchaser, be misleading in any material respect and will comply with the Securities Act, the Investment Company Act, the Securities Act Rules and the Investment Company Act Rules. Delivery by the Underwriters of any such amendments or supplements to the Prospectus will not constitute a waiver of any of the conditions in Section 6 hereof.

(e) The Trust will make generally available to holders of the Trust's securities, as soon as practicable but in no event later than the last day of the 18th full calendar month following the calendar quarter in which the Effective Date falls, an earnings statement, if applicable, satisfying the provisions of Section 11(a) of the Securities Act and, at the option of the Trust, Rule 158 of the Securities Act Rules.

(f) The Trust will take such actions as the Representatives reasonably requests in order to qualify the Shares for offer and sale under the securities or "blue sky" laws of such jurisdictions as the Representatives reasonably designate; provided that the Trust shall not be required in connection therewith or as a condition thereof to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction.

(g) If the transactions contemplated by this Underwriting Agreement are consummated, the Trust shall pay all costs and expenses incident to the performance of the obligations of the Trust under this Underwriting Agreement (to the extent such expenses do not, in the aggregate, exceed $0.02 per Share), including but not limited to costs and expenses of or relating to
(1) the preparation, printing and filing of the registration statement and exhibits to it, each Preliminary Prospectus, the Prospectus and all amendments and supplements thereto, (2) the issuance of the Shares and the preparation and delivery of certificates for the Shares, (3) the registration or qualification of the Shares for offer and sale under the securities or "blue sky" laws of the jurisdictions referred to in the foregoing paragraph, including the fees and disbursements of counsel for the Underwriters in that connection, and the preparation and printing of preliminary and supplemental "blue sky" memoranda,
(4) the furnishing (including costs of design, production, shipping and mailing) to the Underwriters and dealers of copies of each Preliminary Prospectus relating to the Shares, the sales materials, the Prospectus, and all amendments or supplements to the Prospectus, and of the other documents required by this
Section to be so furnished, (5) the filing requirements of the National Association of Securities Dealers, Inc., in connection with its review of the financing, including filing fees and the fees, disbursements and other charges of counsel for the Underwriters in that connection, (6) all transfer taxes, if any, with respect to the sale and

delivery of the Shares to the Underwriters, (7) the listing of the Shares on the New York Stock Exchange, (8) the transfer agent for the Shares, and (9) in addition to the foregoing, an aggregate of $ as partial reimbursement of the costs and expenses of the Underwriters. To the extent the foregoing costs and expenses incident to the performance of the obligations of the Trust under this Underwriting Agreement exceed, in the aggregate, $0.02 per Share Eaton Vance or an affiliate will pay all such excess costs and expenses.

(h) If the transactions contemplated by this Underwriting Agreement are not consummated, except as otherwise provided herein, no party will be under any liability to any other party, except that (1) if this Underwriting Agreement is terminated by (x) the Trust or the Investment Adviser pursuant to any of the provisions hereof (otherwise than pursuant to Section 8 hereof) or (y) by the Representatives or the Underwriters because of any inability, failure or refusal on the part of the Trust or the Investment Adviser to comply with any material terms or because any of the conditions in Section 6 are not satisfied, Eaton Vance or an affiliate and the Trust, jointly and severally, will reimburse the Underwriters for all out-of-pocket expenses (including the reasonable fees, disbursements and other charges of their counsel) reasonably incurred by them in connection with the proposed purchase and sale of the Shares and (2) no Underwriter who has failed or refused to purchase the Shares agreed to be purchased by it under this Underwriting Agreement, in breach of its obligations pursuant to this Underwriting Agreement, will be relieved of liability to the Trust and the Investment Adviser and the other Underwriters for damages occasioned by its default.

(i) The Investment Adviser hereby agrees to waive any and all fees to which it is entitled under the Investment Advisory Agreement and the Administration Agreement for the two month period following the date of this Underwriting Agreement.

(j) Without the prior written consent of the Representatives, the Trust will not offer, sell or register with the Commission, or announce an offering of, any equity securities of the Trust, within 180 days after the Effective Date, except for the Shares as described in the Prospectus and any issuances of Shares of Beneficial Interest pursuant to the dividend reinvestment plan established by the Trust and except in connection with any offering of preferred shares of beneficial interest as contemplated by the Prospectus.

(k) The Trust will use its best efforts to list the Shares on the New York Stock Exchange and comply with the rules and regulations of such exchange.

17

(l) The Trust will direct the investment of the net proceeds of the offering of the Shares in such a manner as to comply with the investment objective and policies of the Trust as described in the Prospectus.

6. CONDITIONS OF THE UNDERWRITERS' OBLIGATIONS. The obligations of the Underwriters to purchase the Shares are subject to the accuracy on the date of this Underwriting Agreement, and on the Closing Dates, of the representations of the Trust and the Investment Adviser in this Underwriting Agreement, to the accuracy and completeness of all statements made by the Trust or the Investment Adviser or any of their respective officers in any certificate delivered to the Representatives or their counsel pursuant to this Underwriting Agreement, to performance by the Trust and the Investment Adviser of their respective obligations under this Underwriting Agreement and to each of the following additional conditions:

(a) The registration statement must have become effective by 5:30 p.m., New York City time, on the date of this Underwriting Agreement or such later date and time as the Managing Representative consents to in writing. The Prospectus must have been filed in accordance with Rule 497(b), (h) or (j), as the case may be, of the Securities Act Rules.

(b) No order suspending the effectiveness of the Registration Statement may be in effect and no proceedings for such purpose may be pending before or, to the knowledge of counsel to the Underwriters, threatened by the Commission, and any requests for additional information on the part of the Commission (to be included in the Registration Statement or the Prospectus or otherwise) must be complied with or waived to the reasonable satisfaction of the Managing Representative.

(c) Since the dates as of which information is given in the Registration Statement and the Prospectus, (1) there must not have been any material change in the Shares of Beneficial Interest or liabilities of the Trust except as set forth in or contemplated by the Prospectus; (2) there must not have been any material adverse change in the general affairs, prospects, management, business, financial condition or results of operations of the Trust or the Investment Adviser whether or not arising from transactions in the ordinary course of business as set forth in or contemplated by the Prospectus;
(3) the Trust must not have sustained any material loss or interference with its business from any court or from legislative or other governmental action, order or decree, whether foreign or domestic, or from any other occurrence not described in the Registration Statement and Prospectus; and (4) there must not have occurred any event that makes untrue or incorrect in any material respect any statement or information contained in the Registration Statement or Prospectus or that is not reflected in the

18

Registration Statement or Prospectus but should be reflected therein in order to make the statements or information therein (in the case of the Prospectus, in light of the circumstances in which they were made) not misleading in any material respect; if, in the judgment of the Managing Representative, any such development referred to in clause (1), (2), (3) or (4) of this paragraph (c) makes it impracticable or inadvisable to consummate the sale and delivery of the Shares pursuant to this Underwriting Agreement by the Underwriters, at the initial public offering price of the Shares.

(d) The Representatives must have received on each Closing Date a certificate, dated such date, of the President or a Vice-President and the chief financial or accounting officer of each of the Trust and the Investment Adviser certifying that (1) the signers have carefully examined the Registration Statement, the Prospectus, and this Underwriting Agreement, (2) the representations of the Trust (with respect to the certificates from such Trust officers) and the representations of the Investment Adviser (with respect to the certificates from such officers of the Investment Adviser) in this Underwriting Agreement are accurate on and as of the date of the certificate, (3) there has not been any material adverse change in the general affairs, prospects, management, business, financial condition or results of operations of the Trust (with respect to the certificates from such Trust officers) or the Investment Adviser (with respect to the certificates from such officers of the Investment Adviser), which change would materially and adversely affect the ability of the Trust or the Investment Adviser, as the case may be, to fulfill its obligations under this Underwriting Agreement or the Investment Advisory Agreement, whether or not arising from transactions in the ordinary course of business, (4) with respect to the Trust only, to the knowledge of such officers after reasonable investigation, no order suspending the effectiveness of the Registration Statement, prohibiting the sale of any of the Shares or otherwise having a material adverse effect on the Trust has been issued and no proceedings for any such purpose are pending before or threatened by the Commission or any other regulatory body, whether foreign or domestic, (5) to the knowledge of the officers of the Investment Adviser, after reasonable investigation, no order having a material adverse effect on the ability of the Investment Adviser to fulfill its obligations under this Underwriting Agreement or the Investment Advisory Agreement, as the case may be, has been issued and no proceedings for any such purpose are pending before or threatened by the Commission or any other regulatory body, whether foreign or domestic, and (6) each of the Trust (with respect to the certificates from such Trust officers) and the Investment Adviser
(with respect to the certificates from such officers of the Investment Adviser) has performed all of its respective agreements that this Underwriting Agreement requires it to perform by such Closing Date (to the extent not waived in writing by the Managing Representative).

19

(e) The Representatives must receive on each Closing Date the opinions dated such Closing Date substantially in the form of Annexes A and B to this Underwriting Agreement from the counsel identified in each such Annex.

(f) The Representatives must receive on each Closing Date from Skadden, Arps, Slate, Meagher & Flom LLP and its affiliated entities, its counsel, an opinion dated such Closing Date with respect to the Trust, the Shares, the Registration Statement and the Prospectus, this Underwriting Agreement and the form and sufficiency of all proceedings taken in connection with the sale and delivery of the Shares. Such opinion and proceedings shall fulfill the requirements of this Section 6(f) only if such opinion and proceedings are satisfactory in all respects to the Representatives. The Trust and the Investment Adviser must have furnished to such counsel such documents as counsel may reasonably request for the purpose of enabling them to render such opinion.

(g) The Representatives must receive on the date this Underwriting Agreement is signed and delivered by the Representatives a signed letter, dated such date, substantially in the form of Annex C to this Underwriting Agreement from the firm of accountants designated in such Annex. The Representatives also must receive on each Closing Date a signed letter from such accountants, dated as of such Closing Date, confirming on the basis of a review in accordance with the procedures set forth in their earlier letter that nothing has come to their attention during the period from a date not more than five business days before the date of this Underwriting Agreement, specified in the letter, to a date not more than five business days before such Closing Date, that would require any change in their letter referred to in the foregoing sentence.

All opinions, letters, evidence and certificates mentioned above or elsewhere in this Underwriting Agreement will comply only if they are in form and scope reasonably satisfactory to counsel for the Underwriters, provided that any such documents, forms of which are annexed hereto, shall be deemed satisfactory to such counsel if substantially in such form.

7. INDEMNIFICATION AND CONTRIBUTION.

(a) Each of the Trust and the Investment Adviser, jointly and severally, will indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of such Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act from and against any and all losses, claims, liabilities, expenses and damages (including, but not limited to, any and all investigative, legal and other

20

expenses reasonably incurred in connection with, and any and all amounts paid in settlement of, any action, suit or proceeding between any of the indemnified parties and any indemnifying parties or between any indemnified party and any third party, or otherwise, or any claim asserted), to which such Underwriter or any such person, or any of them, may become subject under the Securities Act, the Exchange Act, the Investment Company Act, the Advisers Act or other federal or state statutory law or regulation, at common law or otherwise, whether foreign or domestic, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based on (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Preliminary Prospectus, the Prospectus, the sales materials, or any amendment or supplement to the Registration Statement, the Preliminary Prospectus, the Prospectus, the sales materials or in any documents filed under the Exchange Act and deemed to be incorporated by reference into the Registration Statement, the Preliminary Prospectus, the Prospectus, or in any application or other document executed by or on behalf of the Trust or based on written information furnished by or on behalf of the Trust filed in any jurisdiction in order to qualify the Shares under the securities laws thereof or filed with the Commission, (ii) the omission or alleged omission to state, in any or all such documents, a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any act or failure to act or any alleged act or failure to act by such Underwriter in connection with, or relating in any manner to, the Shares or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, liability, expense or damage arising out of or based upon matters covered by clause (i) or (ii) above (provided, however, that neither the Trust nor the Investment Adviser shall be liable under this clause
(iii) to the extent it is finally judicially determined by a court of competent jurisdiction that such loss, claim, liability, expense or damage resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its gross negligence, bad faith or willful misconduct); provided that neither the Trust nor the Investment Adviser will be liable to the extent that such losses, claims, liabilities, expenses or damages are based on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to any underwriter furnished in writing to the Trust by the Representative on behalf of Underwriters expressly for inclusion in the Registration Statement, the Preliminary Prospectus or the Prospectus. This indemnity agreement will be in addition to any liability that the Trust or the Investment Adviser might otherwise have.

(b) Each Underwriter will indemnify and hold harmless the Trust and the Investment Adviser, each person, if any, who controls the Trust or the Investment Adviser within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act, each trustee of the Trust and each officer of the Trust who signs

21

the Registration Statement to the same extent as the foregoing indemnity from the Trust or the Investment Adviser to the Underwriter, but only insofar as losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to such Underwriter furnished in writing to the Trust by such Underwriter expressly for use in the Registration Statement, the Preliminary Prospectus or Prospectus. This indemnity will be in addition to any liability that such Underwriter might otherwise have; provided, however, that in no case shall such Underwriter be liable or responsible for any amount in excess of the fees and commissions received by the Underwriter.

(c) Any party that proposes to assert the right to be indemnified under this Section 7 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 7, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission to so notify such indemnifying party will not relieve it from any liability that it may have to any indemnified party under the foregoing provision of this Section 7 unless, and only to the extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, disbursements and other charges of such counsel will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded (based on the advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party (3) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (4) the

22

indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. Subject to the requirements of Investment Company Act Release No. 11330, all such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly as they are incurred. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. An indemnifying party will not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld). No indemnifying party shall, without the prior written consent of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this Section
7 (whether or not any indemnified party is a party thereto), unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising or that may arise out of such claim, action or proceeding.

(d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this Section 7 is applicable but for any reason is held to be unavailable from the Trust, the Investment Adviser or the Underwriters, the Trust, the Investment Adviser and the Underwriters will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Trust and the Investment Adviser from persons other than the Underwriter, such as persons who control the Trust or the Investment Adviser within the meaning of the Securities Act or the Exchange Act, officers of the Trust who signed the Registration Statement and directors of the Trust, who may also be liable for contribution) to which the Trust, the Investment Adviser and the Underwriters may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Trust and the Investment Adviser on the one hand and the Underwriters on the other. The relative benefits received by the Trust and the Investment Adviser (treated jointly for this purpose as one person) on the one hand and the Underwriters on the other hand shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Trust bear to the total fees and commissions received by the Underwriters. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution

23

shall be made in such proportion as is appropriate to reflect not only such relative benefits referred to in the foregoing sentence but also the relative fault of the Trust and the Investment Adviser (treated jointly for this purpose as one person) on the one hand and the Underwriters on the other hand in connection with respect to the statements or omissions or alleged statements or omissions that resulted in the losses, claims, liabilities, expenses or damages (including any investigative, legal or other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted), as well as any other relevant equitable considerations appropriate in the circumstances. Such relative fault of the parties shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Trust, the Investment Adviser or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission and any other equitable considerations appropriate in the circumstances. The Trust, the Investment Adviser and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense or damage , or action in respect thereof, referred to above in this Section 7(d) shall be deemed to include, for purposes of this Section 7(d) any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding any other provisions of this Section 7(d), the Underwriters shall not be required to contribute any amount in excess of the fees and commissions received by it and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7(d), any person who controls a party to this Agreement within the meaning of the Securities Act will have the same rights to contribution as that party, and each trustee of the Trust and each officer of the Trust who signed the Registration Statement will have the same rights to contribution as the Trust, subject in each case to the provisions hereof. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 7(d), notify such party or parties from whom contribution may be sought, but the omission so to notify will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 7(d). No party will be liable for contribution with respect to any action or claim settled without its written consent (which consent shall not be unreasonably withheld). The Underwriter's obligations to contribute pursuant to this Section 7 are several in

24

proportion to the respective number of Firm Shares set forth opposite their names in Schedule 1 (or such number of Firm Shares as determined pursuant to
Section 9 hereof) and not joint.

(e) Notwithstanding any other provisions in this Section 7, no party shall be entitled to indemnification or contribution under this Agreement against any loss, claim, liability, expense or damage arising by reason of such person's willful misfeasance, bad faith or gross negligence in the performance of its duties hereunder, or by reason of such person's reckless disregard of such person's obligations and duties hereunder.

(f) The Trust and the Investment Adviser acknowledge that the statements with respect to (1) the public offering of the Shares as set forth on the cover page of, (2) stabilization on the inside cover page of and (3) the statements relating to the same and to selling concessions and reallowances of selling concessions under the caption "Underwriting" in the Prospectus constitute the only information furnished in writing to the Trust by the Representative on behalf of the Underwriters expressly for use in such document. The Underwriters severally confirm that these statements are correct in all material respects and were so furnished by or on behalf of the Underwriters severally for use in the Prospectus.

8. TERMINATION. This Underwriting Agreement may be terminated by the Managing Representative by notifying the Trust at any time:

(a) before the later of the effectiveness of the Registration Statement and the time when any of the Shares are first generally offered pursuant to this Underwriting Agreement by the Managing Representative to dealers by letter or telegram;

(b) at or before any Closing Date if, in the sole judgment of the Managing Representative, payment for and delivery of any Shares is rendered impracticable or inadvisable because (1) trading in the equity securities of the Trust is suspended by the Commission or by the principal exchange that lists the Shares, (2) trading in securities generally on the New York Stock Exchange or the Nasdaq Stock Market shall have been suspended or limited or minimum or maximum prices shall have been generally established on such exchange or over-the-counter market, or, (3) additional material governmental restrictions, not in force on the date of this Underwriting Agreement, have been imposed upon trading in securities or trading has been suspended on any U.S. securities exchange, (4) a general banking moratorium has been established by U.S. federal or New York authorities or (5) any material adverse

25

change in the financial or securities markets in the United States or in political, financial or economic conditions in the United States or any outbreak or material escalation of hostilities or declaration by the United States of a national emergency or war or other calamity or crisis shall have occurred the effect of any of which is such as to make it, in the sole judgement of the Managing Representative, impracticable or inadvisable to market the Shares on the terms and in the manner contemplated by the Prospectus; or

(c) at or before any Closing Date, if any of the conditions specified in Section 6 have not been fulfilled when and as required by this Underwriting Agreement.

9. SUBSTITUTION OF UNDERWRITERS. If one or more of the Underwriters fails (other than for a reason sufficient to justify the termination of this Underwriting Agreement) to purchase on any Closing Date the Shares agreed to be purchased on such Closing Date by such Underwriter or Underwriters, the Managing Representative may find one or more substitute underwriters to purchase such Shares or make such other arrangements as the Managing Representative deems advisable, or one or more of the remaining Underwriters may agree to purchase such Shares in such proportions as may be approved by the Managing Representative, in each case upon the terms set forth in this Underwriting Agreement. If no such arrangements have been made within 36 hours after such Closing Date, and

(a) the number of Shares to be purchased by the defaulting Underwriters on such Closing Date does not exceed 10% of the Shares that the Underwriters are obligated to purchase on such Closing Date, each of the nondefaulting Underwriters will be obligated to purchase such Shares on the terms set forth in this Underwriting Agreement in proportion to their respective obligations under this Underwriting Agreement, or

(b) the number of Shares to be purchased by the defaulting Underwriters on such Closing Date exceeds 10% of the Shares to be purchased by all the Underwriters on such Closing Date, the Trust will be entitled to an additional period of 24 hours within which to find one or more substitute underwriters reasonably satisfactory to the Managing Representative to purchase such Shares on the terms set forth in this Underwriting Agreement.

In any such case, either the Managing Representative or the Trust will have the right to postpone the applicable Closing Date for not more than five business days in order that necessary changes and arrangements (including any necessary amendments or supplements to the Registration Statement or the Prospectus) may be

26

effected by the Managing Representative and the Trust. If the number of Shares to be purchased on such Closing Date by such defaulting Underwriter or Underwriters exceeds 10% of the Shares that the Underwriters are obligated to purchase on such Closing Date, and none of the nondefaulting Underwriters or the Trust makes arrangements pursuant to this Section within the period stated for the purchase of the Shares that the defaulting Underwriters agreed to purchase, this Underwriting Agreement will terminate without liability on the part of any nondefaulting Underwriter, the Trust or the Investment Adviser, except as provided in Sections 5(g) and 7 hereof. This Section will not affect the liability of any defaulting Underwriter to the Trust or the nondefaulting Underwriters arising out of such default. A substitute underwriter will become a Underwriter for all purposes of this Underwriting Agreement.

10. MISCELLANEOUS.

(a) The reimbursement, indemnification and contribution agreements in Sections 5(g) and 7 hereof and the representations of the Trust, the Investment Adviser and the Underwriters in this Underwriting Agreement will remain in full force and effect regardless of any termination of this Underwriting Agreement. The reimbursement, indemnification and contribution agreements in Sections 5(g) and 7 hereof and the representations and agreements of the Trust, the Investment Adviser and the Underwriters in this Underwriting Agreement shall survive the Closing Dates and shall remain in full force and effect regardless of any investigation made by or on behalf of any Underwriter, the Trust, the Investment Adviser or any controlling person and delivery of and payment for the Shares.

(b) This Underwriting Agreement is for the benefit of the Underwriters, the Trust, the Investment Adviser and their successors and assigns, and, to the extent expressed in this Underwriting Agreement, for the benefit of persons controlling any of the Underwriters, the Trust, the Investment Adviser and directors and officers of the Trust and the Investment Adviser, and their respective successors and assigns, and no other person, partnership, association or corporation will acquire or have any right under or by virtue of this Underwriting Agreement. The term "successors and assigns" does not include any purchaser of the Shares from any Underwriter merely because of such purchase.

(c) All notices and communications under this Underwriting Agreement will be in writing, effective only on receipt and mailed or delivered, by messenger, facsimile transmission or otherwise, to the Representatives in care of PaineWebber Incorporated, Attn: Financial Institutions Group, 1285 Avenue of the

27

Americas, New York, New York 10019, to the Trust or the Investment Adviser at 24 Federal Street, Boston, MA 02110, Attn: Chief Legal Officer.

(d) This Underwriting Agreement may be signed in multiple counterparts that taken as a whole constitute one agreement.

(e) This Underwriting Agreement will be governed by and construed in accordance with the laws of the State of New York without reference to choice of law principles thereof.

(f) A copy of the Agreement and Declaration of Trust of each of the Trust and the Investment Adviser is on file with the Secretary of The Commonwealth of Massachusetts, and notice hereby is given that this Underwriting Agreement is executed on behalf of the respective Trustees of the Trust and the Investment Adviser as Trustees and not individually and that the obligations or arising out of this Underwriting Agreement are not binding upon any of the Trustees or beneficiaries individually but are binding only upon the respective assets and properties of the Trust and the Investment Adviser.

28

ANNEX A

FORM OF OPINION OF
KIRKPATRICK & LOCKHART LLC REGARDING THE TRUST

11. The Registration Statement and all post-effective amendments, if any, are effective under the Securities Act and no stop order with respect thereto has been issued and no proceeding for that purpose has been instituted or, to the best of our knowledge, is threatened by the Commission. Any filing of the Prospectus or any supplements thereto required under Rule 497 of the Securities Act Rules prior to the date hereof have been made in the manner and within the time required by such rule.

12. The Trust has been duly formed and is validly existing as a Massachusetts business trust under the laws of the Commonwealth of Massachusetts, with full power and authority to conduct all the activities conducted by it, to own or lease all assets owned (or to be owned) or leased (or to be leased) by it and to conduct its business as described in the Registration Statement and Prospectus, and the Trust is duly licensed and qualified to do business and in good standing in each jurisdiction in which its ownership or leasing of property or its conducting of business requires such qualification, and the Trust owns, possesses or has obtained and currently maintains all governmental licenses, permits, consents, orders, approvals and other authorizations, whether foreign or domestic, necessary to carry on its business as contemplated in the Prospectus. The Trust has no subsidiaries.

13. The capitalization of the Trust is as set forth in the Registration Statement and the Prospectus. The Shares of Beneficial Interest of the Trust conform in all respects to the description of them in the Prospectus. All the outstanding Shares of Beneficial Interest have been duly authorized and are validly issued, fully paid and nonassessable. The Shares to be issued and delivered to and paid for by the Underwriters in accordance with the Underwriting Agreement against payment therefor as provided by the Underwriting Agreement have been duly authorized and when issued and delivered to the Underwriters will have been validly issued and will be fully paid and nonassessable (except as described in the Registration Statement). No person is entitled to any preemptive or other similar rights with respect to the Shares.

14. The Trust is duly registered with the Commission under the Investment Company Act as a non-diversified, closed-end management investment company and all action under the Securities Act, the Investment Company Act, the Securities Act Rules and the Investment Company Act Rules, as the case may be, necessary to make the public offering and consummate the sale of the Shares as provided in the Underwriting Agreement has or will have been taken by the Trust.

A-1

15.

16. None of (A) the execution and delivery by the Trust of the Trust Agreements, (B) the issue and sale by the Trust of the Shares as contemplated by the Underwriting Agreement and (C) the performance by the Trust of its obligations under the Trust Agreements or consummation by the Trust of the other transactions contemplated by the Trust Agreements conflicts with or will conflict with, or results or will result in a breach of, the Declaration of Trust or the By-laws of the Trust or any agreement or instrument to which the Trust is a party or by which the Trust is bound, or any law, rule or regulation, or order of any court, governmental instrumentality, securities exchange or association or arbitrator, whether foreign or domestic, applicable to the Trust, except that we express no opinion as to the securities or "blue sky" laws applicable in connection with the purchase and distribution of the Shares by the Underwriters pursuant to the Underwriting Agreement.

20. There is no action, suit or proceeding before or by any court, commission, regulatory body, administrative agency or other governmental agency or body, foreign or domestic, now pending or, to our knowledge, threatened against or affecting the Trust, which is required to be disclosed in the Prospectus that is not disclosed in the Prospectus, and there are no contracts, franchises or other documents that are of a character required to be described in, or that are required to be filed as exhibits to, the Registration Statement that have not been described or filed as required.

FORM OF ACCOUNTANT'S LETTER

October 27, 1998

The Board of Trustees of
Eaton Vance Senior Income Trust
24 Federal Street
Boston, Massachusetts 02110

PaineWebber Incorporated
1285 Avenue of the Americas
New York, New York 10019
as Managing Representative of the Underwriters

Ladies and Gentlemen:

We have audited the statement of assets and liabilities of Eaton Vance Senior Income Trust (the "Trust") as of October 23, 1998 included in the Registration Statement on Form N-2 filed by the Trust under the Securities Act of 1933 (the "Act") (File No. 333-64151) and under the Investment Company Act of 1940 (the "1940 Act") (File No. 811-09013); such statement and our report with respect to such statement are included in the Registration Statement.

In connection with the Registration Statement:

1. We are independent public accountants with respect to the Trust within the meaning of the Act and the applicable rules and regulations thereunder.

2. In our opinion, the statement of assets and liabilities included in the Registration Statement and audited by us complies as to form in all respects with the applicable accounting requirements of the Act, the 1940 Act and the respective rules and regulations thereunder.

3. For purposes of this letter we have read the minutes of all meetings of the Shareholders, the Board of Trustees and all Committees of the Board of Trustees of the Trust as set forth in the minute books at the offices of the Trust, officials of the Trust having advised us that the minutes of all such meetings through October 26, 1998, were set forth therein.

C-1

4. Trust officials have advised us that no financial statements as of any date subsequent to October 23, 1998, are available. We have made inquiries of certain officials of the Trust who have responsibility for financial and accounting matters regarding whether there was any change at October 27, 1998, in the capital shares or net assets of the Trust as compared with amounts shown in the October 23, 1998 statement of assets and liabilities included in the Registration Statement, except for changes that the Registration Statement discloses have occurred or may occur. On the basis of our inquiries and our reading of the minutes as described in Paragraph 3, nothing came to our attention that caused us to believe that there were any such changes.

The foregoing procedures do not constitute an audit made in accordance with generally accepted auditing standards. Accordingly, we make no representations as to the sufficiency of the foregoing procedures for your purposes.

This letter is solely for the information of the addressees and to assist the underwriters in conducting and documenting their investigation of the affairs of the Trust in connection with the offering of the securities covered by the Registration Statement, and is not to be used, circulated, quoted or otherwise referred to within or without the underwriting group for any other purpose, including but not limited to the registration, purchase or sale of securities, nor is it to be filed with or referred to in whole or in part in the Registration Statement or any other document, except that reference may be made to it in the underwriting agreement or in any list of closing documents pertaining to the offering of the securities covered by the Registration Statement.

Very truly yours,

DELOITTE & TOUCHE LLP

Exhibit (h)(2)

AMENDED AND RESTATED
MASTER AGREEMENT AMONG UNDERWRITERS

June 11, 1984

PaineWebber Incorporated
1285 Avenue of the Americas
New York, New York 10019

Gentlemen:

1. General. We understand that PaineWebber Incorporated ("PWI") is entering into this Agreement in counterparts with us and other firms who may be underwriters for issues of securities for which PWI is acting as Representative or one of the Representatives of the several underwriters. This Agreement shall apply to any offering of securities in which we elect to act as an underwriter after receipt of a telegram, telex or other form of written communication ("Written Communication") from PWI stating the identity of the issuer and, if different from the issuer, the seller or sellers of such securities, the securities proposed to be offered, whether the underwriters are afforded an option to purchase additional securities to cover over-allotments, the price to underwriters, public offering price and date, interest rate, if any, and other variables, the amount of our proposed participation and the names of the other Representatives, if any, and that our participation as an underwriter in the proposed offering shall be subject to the provisions of this Agreement. Upon our telegraphic acceptance of such Written Communication we shall become one of the underwriters of such issue for the amount specified in the Written Communication, and this Agreement shall become binding upon us and the Representatives with respect to such offering. The obligations of each underwriter shall be several and not joint. The issuer of the securities offered in any offering of securities made pursuant to this Agreement is hereinafter referred to as the "Company", and such securities are hereinafter called the "Securities". The seller or sellers of the Securities (including, if applicable, the Company) are hereinafter referred to collectively as the "Seller". All references herein to "you" or the "Representatives" shall include PWI and the other firms, if any, which are named as Representatives in the Written Communication. The Securities to be offered in any offering may but need not be registered in a shelf registration pursuant to Rule 415 under the Securities Act of 1933 (the "Securities Act"). The following provisions of this Agreement shall apply separately to each individual offering of Securities.

2. Underwriting Arrangements. The Representatives shall determine which signatories to this Agreement will be invited to become underwriters for the Securities. Changes may be made by the Representatives in those who are to be underwriters and in the respective amounts of Securities to be purchased by them, but the amount of Securities to be purchased by us as set forth in the Written Communication to us will not be changed without our consent except as provided herein or in the underwriting agreement (the "Underwriting Agreement") with the Seller covering the Securities. We authorize you on our behalf to execute and deliver the Underwriting Agreement in such form as you determine and to take such action as you deem


advisable in connection with the performance of the Underwriting Agreement and this Agreement and the purchase, carrying, sale and distribution of the Securities, including the election to exercise any option to purchase additional Securities to cover over-allotments if so provided. The parties on whose behalf you execute the Underwriting Agreement are hereinafter called the "Underwriters". You may waive performance or satisfaction by the Seller of certain of its obligations or conditions included in the Underwriting Agreement, if in your judgment such waiver will not have a material adverse effect upon the interests of the Underwriters. It is understood that, if so specified in the Written Communication for the issue, arrangements may be made for the sale of Securities by the Seller pursuant to delayed delivery contracts. Such Securities are hereinafter referred to as "Delayed Delivery Securities", and such contracts as "Delayed Delivery Contracts". References herein to delayed delivery and Delayed Delivery Contracts apply only to offerings in which delayed delivery is authorized. The term "underwriting obligation", as used in this Agreement with respect to any Underwriter, shall refer to the principal amount or number of shares of the Securities which such Underwriter is obligated to purchase pursuant to the provisions of the Underwriting Agreement, without regard to any reduction in such obligation as a result of Delayed Delivery Contracts which are entered into by the Seller.

As compensation for your services we will pay a management fee as specified in the Written Communication for the issue (without deduction in respect of Delayed Delivery Securities), and you may charge our account therefor. If there is more than one Representative, such compensation will be divided among the Representatives in such proportions as they determine.

3. Prospectus and Registration Statement. You will furnish to us as soon as possible copies of the prospectus or supplemented prospectus to be used in connection with the offering of the Securities. As used herein with respect to an offering of Securities registered under the Securities Act, "Prospectus" means the form of prospectus (including any supplements) authorized for use in connection with such offering, and "Registration Statement" means the registration statement, as amended, filed under the Securities Act pursuant to which the Securities are registered under the Securities Act. As used herein with respect to an offering of Securities not registered under the Securities Act, "Prospectus" or "Registration Statement" means the form of final offering circular (including any supplements) authorized for use in connection with such offering and "preliminary prospectus" means any preliminary offering circular authorized for use in connection with such offering. We consent to being named in the prospectus as one of the Underwriters of the Securities.

4. Public Offering. (a) In connection with the public offering of the Securities, we authorize you, in your discretion

(i) to determine the time of the initial public offering, to change the public offering price and the concessions and discounts to dealers after the initial public offering, to furnish the Company with the information to be included in the Registration Statement or Prospectus with respect to the terms of offering, and to determine all matters relating to advertising and communications with dealers or others;

2

(ii) to reserve for sale to dealers selected by you ("Selected Dealers") and to others, and to reserve for sale pursuant to Delayed Delivery Contracts (including Delayed Delivery Contracts arranged by you through Selected Dealers), all or any part of our Securities, which reservations for sales to others and for sales pursuant to Delayed Delivery Contracts not arranged through Selected Dealers are to be as nearly as practicable in proportion to the respective underwriting obligations of the Underwriters, unless you agree to a smaller proportion at the request of any Underwriter, and such other reservations to be in such proportions as you determine, and, from time to time, to add to the reserved Securities any Securities retained by us remaining unsold and to release to us any of our Securities reserved but not sold;

(iii) to sell reserved Securities, as nearly as practicable in proportion to the respective reservations, to Selected Dealers at the public offering price less the Selected Dealers' concession and to others at the public offering price; and

(iv) to buy Securities for our account from Selected Dealers at the public offering price less such amount not in excess of the Selected Dealers' concession as you determine.

If, in accordance with the terms of offering set forth in the Prospectus, the offering of the Securities is not at a fixed price but at varying prices set by individual Underwriters based on market prices or at negotiated prices, the provisions of clause (i) above relating to your right to change the public offering price and concessions and discounts to dealers shall not apply, and other references in this Section and elsewhere in this Agreement to the public offering price or Selected Dealers' concession shall be deemed to mean the prices and concessions determined by you from time to time in your discretion.

Sales of Securities between Underwriters may be made with your prior consent, or as you deem advisable for Blue Sky purposes.

After advice from you that the Securities are released for public offering, we will offer to the public in conformity with the terms of offering set forth in the Prospectus such of our Securities as you advise us are not reserved.

Any Securities sold by us (otherwise than through you) which you purchase in the open market for the account of any Underwriter will be repurchased by us on demand at a price equal to the total cost of such purchase including any taxes on redelivery, commissions, accrued interest and dividends. Securities delivered on such repurchase need not be the identical certificates so purchased. In lieu of such action you may in your discretion sell for our account the Securities so purchased and debit or credit our account for the loss or profit resulting from such sale, or charge our account with an amount not in excess of the Selected Dealers' concession with respect to such Securities.

(b) We authorize you to act on our behalf in making all arrangements for the solicitation of offers to purchase Delayed Delivery Securities from the Seller pursuant to Delayed Delivery Contracts and we agree that all such arrangements will be made only through you,

3

directly or through Selected Dealers (including Underwriters acting as Selected Dealers) to whom you may pay a commission as provided in the Prospectus and herein.

The obligation of each of the Underwriters to purchase and pay for Securities as set forth in the Underwriting Agreement shall be reduced in the proportion provided for therein, except that (i) as to any Delayed Delivery Contract determined by you, in your discretion, to have been directed and allocated by a purchaser to a particular Underwriter, such obligation of such Underwriters shall be reduced by the amount of Delayed Delivery Securities covered thereby, (ii) as to any Delayed Delivery Contracts for which arrangements are made through Selected Dealers, such obligation of each Underwriter shall be reduced as nearly as practicable in the proportion determined by you that the amount of Securities of such Underwriter reserved and sold pursuant to Delayed Delivery Contracts arranged through Selected Dealers bears to the total Securities so reserved and sold, and (iii) such reductions shall be rounded, as you shall determine, to the nearest $1,000 principal amount or whole share of the Securities.

The fee payable to each Underwriter with respect to Delayed Delivery Securities pursuant to the Underwriting Agreement shall be credited to the account of such Underwriter based upon the amount by which such Underwriter's underwriting obligation is reduced as specified in the preceding paragraph.

If the amount of Delayed Delivery Securities applied to reduce an Underwriter's underwriting obligation and the amount of Securities sold by or for the account of such Underwriter exceeds such Underwriter's underwriting obligation, there shall be credited to such Underwriter in connection with such excess amount of Securities only the amount of the Selected Dealers' concession with respect thereto.

The commissions payable to Selected Dealers in respect of Delayed Delivery Contracts arranged through them shall be charged to each Underwriter in the proportion which the amount of Securities of such Underwriter reserved and sold pursuant to Delayed Delivery Contracts arranged through Selected Dealers bears to the total Securities so reserved and sold.

5. Payment and Delivery. We authorize you to make payment on our behalf to the Seller of the purchase price of our Securities, to take delivery of our Securities, registered as you may direct in order to facilitate deliveries, and to deliver our reserved Securities against sales. At your request we will pay you, as you direct, (i) an amount equal to the public offering price, less the selling concession, of either our Securities or our unreserved Securities or
(ii) the amount set forth or indicated in the Written Communication with respect to the Securities, and such payment will be credited to our account and applied to the payment of the purchase price. After you receive payment for reserved Securities sold for our account, you will remit to us the purchase price (if any) paid by us for such Securities and credit or debit our account with the difference between the sale prices and the purchase price thereof. You will deliver to us our unreserved Securities promptly, and our reserved but unsold Securities, against payment of the purchase price therefor (except in the case of Securities for which payment has previously been made), as soon as practicable after the termination of the provisions referred to in Section 9, except that if the aggregate amount of reserved but unsold Securities upon such termination does not exceed

4

10% of the total amount of the Securities, you may in your discretion sell such reserved but unsold Securities for the accounts of the several Underwriters as soon as practicable after such termination, at such prices and in such manner as you determine. Unless we promptly give you written instructions otherwise, if transactions in the Securities may be settled through the facilities of The Depository Trust Company, payment for and delivery of securities purchased by us will be made through such facilities, if we are a member, or if we are not a member, settlement may be made through our ordinary correspondent who is a member.

6. Authority to Borrow. In connection with the purchase or carrying of our Securities or other securities purchased for our account, we authorize you, in your discretion, to advance your funds for our account, charging current interest rates, to arrange loans for our account, and in connection therewith to execute and deliver any notes or other instruments and hold or pledge as security any of our Securities or such other securities. Any lender may rely upon your instructions in all matters relating to any such loan. Any Securities or such other securities held by you for our account may be delivered to us for carrying purposes, and if so delivered will be redelivered to you upon demand.

7. Stabilization and Over-Allotment. We authorize you, in your discretion, to make purchases and sales of Securities, any other securities of the Company of the same class and series and any other securities of the Company which you may designate in the open market or otherwise, for long or short account, on such terms as you deem advisable, and, in arranging sales, to over-allot and cover any such over-allotment, at your discretion, by purchasing Securities, exercising the over-allotment option, if any, indicated in the Written Communication, or both. Such purchases and sales and over-allotments will be made for the accounts of the Underwriters as nearly as practicable in proportion to their respective underwriting obligations. It is understood that you may have made purchases of securities of the Company for stabilizing purposes prior to the time when we become one of the Underwriters, and we agree that any securities so purchased shall be treated as having been purchased for the respective accounts of the Underwriters pursuant to the foregoing authorization. We authorize you, in your discretion, to cover any short position incurred pursuant to this Section by purchasing securities on such terms as you deem advisable. At no time will our net commitment under the foregoing provisions of this Section exceed 15% of our underwriting obligation. Solely for purposes of the immediately preceding sentence, our "underwriting obligation" shall be deemed to exclude any Securities which we are obligated to purchase solely by virtue of the exercise of an over-allotment option. We will on demand take up at cost any securities so purchased and deliver any securities so sold or over-alloted for our account, and, if any other Underwriter defaults in its corresponding obligation, we will assume our proportionate share of such obligation without relieving the defaulting Underwriter from liability. Upon request, we will advise you of the Securities retained by us and unsold and will sell to you for the account of one or more of the Underwriters such of our unsold Securities and at such price, not less than the net price to Selected Dealers nor more than the public offering price, as you determine.

8. Open Market Transactions. We and you agree not to bid for, purchase, attempt to induce others to purchase, or sell, directly or indirectly, any Securities, any other securities of the Company of the same class and series and any other securities of the Company which you may

5

designate, except as brokers pursuant to unsolicited orders and as otherwise provided in this Agreement. If the Securities are common stock or securities convertible into common stock, we and you also agree not to effect, or attempt to induce others to effect, directly or indirectly, any transactions in or relating to put or call options on any stock of the Company, except to the extent permitted by Rule 10b-6 under the Securities Exchange Act of 1934 (the "Exchange Act") as interpreted by the Securities and Exchange Commission. An opening uncovered writing transaction in options to acquire Securities for our account or for the account of any customer shall be deemed, for purposes of the preceding sentence, to be a transaction effected by us in or relating to put or call options on stock of the Company not permitted by Rule 10b-6. The term "opening uncovered writing transaction" means an opening sale transaction where the seller intends to become a writer of an option to purchase stock which it does not own or have the right to acquire upon exercise of conversion or option rights.

9. Termination as to an Offering. The provisions of the last two paragraphs of Section 4(a), the first sentence of Section 7, and Section 8 will terminate at the close of business on the thirtieth day after the date of the initial public offering of the Securities, unless sooner terminated as hereinafter provided. You may terminate such provision as to such offering at any time by notice to us to the effect that the offering provisions of this Agreement as to such offering are terminated.

10. Expenses and Settlement. You may charge our account with any transfer taxes on sales made by you of Securities purchased by us under the Underwriting Agreement and with our proportionate shares (based upon our underwriting obligation) of all other expenses incurred by you under this Agreement or in connection with the purchase, carrying, sale or distribution of the Securities. The accounts hereunder will be settled as promptly as practicable after the termination of the provisions referred to in Section 9, but you may reserve such amount as you deem advisable for additional expenses. Your determination of the amount to be paid to or by us will be conclusive. You may at any time make partial distributions of credit balances or call for payment of debit balances. Any of our funds in your hands may be held with your general funds without accountability for interest. Notwithstanding any settlement, we will remain liable for any taxes on transfers for our account, and for our proportionate share (based upon our underwriting obligation) of all expenses and liabilities which may be incurred by or for the accounts of the Underwriters.

11. Default by Underwriters. Default by one or more Underwriters hereunder or under the Underwriting Agreement will not release the other Underwriters from their obligations or affect the liability of any defaulting Underwriter to the other Underwriters for damages resulting from such default. If one or more Underwriters default under the Underwriting Agreement, you may arrange for the purchase by others, including nondefaulting Underwriters, of Securities not taken up by the defaulting Underwriter or Underwriters.

12. Position of Representatives. You will be under no liability to us for any act or omission except for obligations expressly assumed by you herein, and no obligations on your part will be implied or inferred herefrom. Your authority hereunder and under the Underwriting Agreement may be exercised by you jointly or by PWI. The rights and liabilities of the

6

Underwriters are several and not joint, and nothing will constitute the Underwriters a partnership, association or separate entity.

If for Federal income tax purposes the Underwriters should be deemed to constitute a partnership then each Underwriter elects to be excluded from the application of Subchapter K, Chapter 1, Subtitle A, of the Internal Revenue Code of 1954, as amended. You, as Representatives of the several Underwriters, are authorized, in your discretion, to execute on behalf of the Underwriters such evidence of such election as may be required by the Internal Revenue Service.

13. Indemnification. We will indemnify and hold harmless each other Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act to the extent and upon the terms upon which each Underwriter agrees to indemnify the Company and any other Seller in the Underwriting Agreement.

14. Contribution. Each Underwriter (including you) will pay upon your request, as contribution, its proportionate share, based upon its underwriting obligation, of any losses, claims, damages or liabilities, joint or several, paid or incurred by any Underwriter to any person other than an Underwriter, arising out of or based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, any amendment or supplement thereto or any related preliminary prospectus or any other selling or advertising material approved by you for use by the Underwriters in connection with the sale of the Securities, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading (other than an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by an Underwriter specifically for use therein); and will pay such proportionate share of any legal or other expenses reasonably incurred by you or with your consent in connection with investigating or defending against any such loss, claim, damage or liability, or any action or proceeding (including any action or proceeding brought by a governmental or regulatory body) in respect thereof. In determining the amount of any Underwriter's obligation under this Section, appropriate adjustment may be made by you to reflect any amounts received by any one or more Underwriters in respect of such claim from the Company or any other Seller pursuant to the Underwriting Agreement or otherwise. There shall be credited against any amount paid or payable by us pursuant to this Section any loss, damage, liability or expense which is incurred by us as a result of any such claim asserted against us, and if such loss, claim, damage, liability or expense is incurred by us subsequent to any payment by us pursuant to this Section, appropriate provision shall be made to effect such credit, by refund or otherwise. If any such claim is asserted, you may take such action in connection therewith as you deem necessary or desirable, including retention of counsel for the Underwriters, and in your discretion separate counsel for any particular Underwriter or group of Underwriters, and the fees and disbursements of any counsel so retained by you shall be included in the amounts payable pursuant to this Section. In determining amounts payable pursuant to this Section, any loss, claim, damage, liability or expense incurred by any person controlling any Underwriter within the meaning of Section 15 of the Securities Act which has been incurred by reason of such control relationship shall be deemed to have been incurred by such Underwriter.

7

Any Underwriter may elect to retain at its own expense its own counsel. You may settle or consent to the settlement of any such claim, on advice of counsel retained by you, with the approval of a majority in interest of the Underwriters. Whenever you receive notice of the assertion of any claim to which the provisions of this Section would be applicable, you will give prompt notice thereof to each Underwriter. You will also furnish each Underwriter with periodic reports, at such times as you deem appropriate, as to the status of such claim and the action taken by you in connection therewith. If any Underwriter or Underwriters default in their obligation to make any payments under this Section, each nondefaulting Underwriter shall be obligated to pay its proportionate share of all defaulted payments, based upon such Underwriter's underwriting obligation as related to the underwriting obligations of all nondefaulting Underwriters.

15. Reports and Blue Sky Matters. We authorize you to file with the Securities and Exchange Commission and any other governmental agency any reports required in connection with any transactions effected by you for our account pursuant to this Agreement, and we will furnish any information needed for such reports. If you effect stabilizing purchases pursuant to Section 7, you will notify us promptly of the initiation and termination thereof. If stabilization is effected we will file with you, c/o PWI, not later than the fifth full business day following the termination of stabilization, any report required to be filed pursuant to Rule 17a-2 under the Exchange Act. You will not have any responsibility with respect to the right of any Underwriter or other person to sell the Securities in any jurisdiction, notwithstanding any information you may furnish in that connection.

16. Representations and Agreements. (a) You represent that you are a member in good standing of the National Association of Securities Dealers, Inc. (the "NASD"), and we represent that we are either a member in good standing of the NASD or a foreign dealer not eligible for membership. If we are such a member we agree that in making sale of the Securities we will comply with all applicable rules of the NASD, including, without limitation, the NASD's interpretation with Respect to Free-Riding and Withholding and Section 24 of Article III of the Rules of Fair Practice. If we are such a foreign dealer, we agree not to offer or sell any Securities in the United States of America except through you and in making sales of Securities outside the United States of America we agree to comply as though we were a member with such interpretation and Sections 8, 24 and 36 of Article III of the NASD's Rules of Fair Practice and to comply with Section 25 of such Article III as it applies to a nonmember broker or dealer in a foreign country.

(b) We understand that it is our responsibility to examine the Registration Statement, the Prospectus, any amendment or supplement thereto relating to the offering of the Securities, any preliminary prospectus and the material, if any, incorporated by reference therein and we will familiarize ourselves with the terms of the Securities and the other terms of the offering thereof which are to be reflected in the Prospectus and the Written Communication with respect thereto. You are authorized, with the approval of counsel for the Underwriters, to approve on our behalf any amendments or supplements to the Registration Statement or the Prospectus.

(c) We confirm that the information that we have given or are deemed to have given in response to the Master Underwriters' Questionnaire attached as Exhibit A hereto (which

8

information has been furnished to the Company for use in the Registration Statement or the Prospectus) is correct. We will notify you immediately of any development before the termination of this Agreement under Section 9 as to the offering of the Securities which makes untrue or incomplete any information that we have given or are deemed to have given in response to the Master Underwriters' Questionnaire.

(d) Unless we have promptly notified you in writing otherwise, our name as it should appear in the Prospectus and our address are set forth on the signature page hereof.

(e)(i) If the Securities are being registered under the Securities Act, we represent that we are familiar with Rule 15c2-8 under the Exchange Act relating to the distribution of preliminary and final prospectuses and agree that we will comply therewith; we agree to keep an accurate record of the distribution (including dates, number of copies and persons to whom sent) by us of copies of the Registration Statement, the Prospectus or any preliminary prospectus (or any amendment or supplement to any thereof), and promptly upon request by you, to bring all subsequent changes to the attention of anyone to whom such material shall have been distributed; and we agree to furnish to persons who receive a confirmation of sale a copy of the Prospectus filed pursuant to Rule 424(b) or Rule 424(c) under the Securities Act.

(ii) If the Securities will not be registered under the Securities Act, we agree that we will deliver all preliminary and final offering circulars required for compliance with the applicable laws and regulations governing the use and distribution of offering circulars by underwriters, and, to the extent consistent with such laws and regulations, we confirm that we have delivered and agree that we will deliver all preliminary and final offering circulars which would be required if the provisions of Rule 15c2-8 under the Exchange Act applied to this offering.

(f) If the Securities are being registered under the Securities Act, we agree that, if we are advised by you that the Company was not, immediately prior to the filing of the Registration Statement, subject to the requirements of
Section 13(a) or 15(d) of the Exchange Act, we will not, without your consent, sell any of the Securities to an account over which we exercise discretionary authority.

17. Miscellaneous. (a) This Agreement may be terminated by either party hereto upon five business days' written notice to the other party; provided that with respect to any offering of Securities for which a Written Communication was sent by you and accepted by us prior to such notice, this Agreement shall remain in full force and effect as to such offering and shall terminate with respect to such offering in accordance with the provisions of Section 9. This Agreement may be supplemented or amended by you by written notice thereof to us, and any such supplement or amendment to this Agreement shall be effective with respect to any offering of securities to which this Agreement applies after the date of such supplement or amendment. Each reference to "this Agreement" herein shall, as appropriate, be to this Agreement as so amended and supplemented.

9

(b) This Agreement and the terms and conditions set forth herein with respect to any offering of Securities together with such supplementary terms and conditions with respect to such offering as may be contained in any Written Communication from you to us in connection therewith shall be governed by, and construed in accordance with, the laws of the State of New York.

Very truly yours,

Exhibit (h)(3)

AMENDED AND RESTATED MASTER SELECTED DEALER AGREEMENT

June 11, 1984

PaineWebber Incorporated
1285 Avenue of the Americas
New York, New York 10019

Gentlemen:

1. General. We understand that PaineWebber Incorporated ("PW") is entering into this Agreement with us and other firms who may be offered the right to purchase as principal a portion of securities being distributed to the public. The terms and conditions of this Agreement shall be applicable to any public offering of securities ("Securities") wherein PW (acting for its own account or for the account of any underwriting or similar group or syndicate) is responsible for managing or otherwise implementing the sale of the Securities to selected dealers ("Selected Dealers") and has expressly informed us that such terms and conditions shall be applicable. Any such offering of Securities to us as a Selected Dealer is hereinafter called an "Offering". In the case of any Offering in which you are acting for the account of any underwriting or similar group or syndicate ("Underwriters"), the terms and conditions of this Agreement shall be for the benefit of, and binding upon, such Underwriters, including, in the case of any Offering in which you are acting with others as representatives of Underwriters, such other representatives. The term "preliminary prospectus" means, in the case of an Offering registered under the Securities Act of 1933 (the "Securities Act"), any preliminary prospectus relating to an Offering of Securities or any preliminary prospectus supplement together with a prospectus relating to an Offering of Securities and, in the case of an Offering not registered under the Securities Act, any preliminary offering circular relating to an Offering of Securities or any preliminary offering circular supplement together with an offering circular relating to an Offering of Securities; the term "Prospectus" means in the case of an Offering registered under the Securities Act of 1933 (the "Securities Act"), the prospectus, together with the final prospectus supplement, if any, relating to such Offering of Securities, filed pursuant to Rule 424(b) or Rule 424(c) under the Securities Act and, in the case of an Offering not registered under the Securities Act, the final offering circular, including any supplements, relating to such Offering of Securities.

2. Conditions of Offering; Acceptance and Purchase. Any Offering will be subject to delivery of the Securities and their acceptance by you and any other Underwriters may be subject to the approval of all legal matters by counsel and the satisfaction of other conditions, and may be made on the basis of reservation of Securities or an allotment against subscription. You will advise us by telegram, telex or other form of written communication ("Written Communication") of the particular method and supplementary terms and conditions (including, without limitation, the information as to prices and offering date referred to in Section 3(b)) of any Offering in which we are invited to participate. To the extent such supplementary terms and conditions are inconsistent with any provision herein,


such terms and conditions shall supersede any such provision. Unless otherwise indicated in any such Written Communication, acceptances and other communications by us with respect to any Offering should be sent to PaineWebber Incorporated, 1285 Avenue of the Americas, New York, New York 10019. You reserve the right to reject any acceptance in whole or in part. Payment for Securities purchased by us is to be made at such office as you may designate, at the public offering price, or, if you shall so advise us, at such price less the concession to dealers or at the price set forth or indicated in a Written Communication, on such date as you shall determine, on one day's prior notice to us, by certified or official bank check in New York Clearing House funds payable to the order of PaineWebber Incorporated, against delivery of certificates evidencing such Securities. If payment is made for Securities purchased by us at the public offering price, the concession to which we shall be entitled will be paid to us upon termination of the provisions of Section 3(b) with respect to such Securities.

Unless we promptly give you written instructions otherwise, if transactions in the Securities may be settled through the facilities of The Depository Trust Company, payment for and delivery of Securities purchased by us will be made through such facilities if we are a member, or if we are not a member, settlement may be made through our ordinary correspondent who is a member.

3. Representations, Warranties and Agreements. (a) Prospectuses. You shall provide us with such number of copies of each preliminary prospectus, the Prospectus and any supplement thereto relating to each Offering as we may reasonably request. If the Securities will be registered under the Securities Act, we represent that we are familiar with Rule 15c2-8 under the Exchange Act relating to the distribution of preliminary and final prospectuses and agree that we will comply therewith; we agree to keep an accurate record of our distribution (including dates, number of copies and persons to whom sent) of copies of the Prospectus or any preliminary prospectus (or any amendment or supplement to any thereof), and promptly upon request by you, to bring all subsequent changes to the attention of anyone to whom such material shall have been furnished; and we agree to furnish to persons who receive a confirmation of sale a copy of the Prospectus filed pursuant to Rule 424(b) or Rule 424(c) under the Securities Act. If the Securities will not be registered under the Securities Act, we agree that we will deliver all preliminary and final offering circulars required for compliance with the applicable laws and regulations governing the use and distribution of the offering circulars by underwriters, and, to the extent consistent with such laws and regulations, we confirm that we have delivered and agree that we will deliver all preliminary and final offering circulars which would be required if the provisions of Rule 15c2-8 under the Exchange Act applied to this offering. We agree that in purchasing Securities in an Offering we will rely upon no statements whatsoever, written or oral, other than the statements in the Prospectus delivered to us by you. We will not be authorized by the issuer or other seller of Securities offered pursuant to a Prospectus or by any Underwriters to give any information or to make any representation not contained in the Prospectus in connection with the sale of such Securities.

2

(b) Offer and Sale of the Public. With respect to any Offering of Securities, you will inform us by a Written Communication of the public offering price, the selling concession, the reallowance (if any) to dealers and the time when we may commence selling Securities to the public. After such public offering has commenced, you may change the public offering price, the selling concession and the reallowance to dealers. With respect to each Offering of Securities, until the provisions of this Section 3(b) shall be terminated pursuant to Section 4, we agree to offer Securities to the public only at the public offering price, except that if a reallowance is in effect, a reallowance from the public offering price not in excess of such reallowance may be allowed as consideration for services rendered in distribution to dealers who are actually engaged in the investment banking or securities business, who execute the written agreement prescribed by Section 24(c) of Article III of the Rules of Fair Practice of the National Association of Securities Dealers, Inc. (the "NASD"), and who are either members in good standing of the NASD or foreign brokers or dealers not eligible for membership in the NASD who represent to us that they will promptly reoffer such Securities at the public offering price and will abide by the conditions with respect to foreign brokers and dealers set forth in Section 3(e).

(c) Stabilization and Over-Allotment. You may, with respect to any Offering, be authorized to over-allot in arranging sales to Selected Dealers, to purchase and sell Securities, any other securities of the issuer of the Securities of the same class and series and any other securities of such issuer that you may designate for long or short account and to stabilize or maintain the market price of the Securities. We agree to advise you from time to time upon request, prior to the termination of the provisions of Section 3(b) with respect to any Offering, of the amount of Securities purchased by us hereunder remaining unsold and we will, upon your request, sell to you, for the accounts of the Underwriters, such amount of Securities as you may designate, at the public offering price thereof less an amount to be determined by you not in excess of the concession to dealers. In the event that prior to the later of (i) the termination of the provisions of Section 3(b) with respect to any Offering, or (ii) the covering by you of any short position created by you in connection with such Offering for your account or the account of one or more Underwriters, you purchase or contract to purchase for the account of any of the Underwriters, in the open market or otherwise, any Securities theretofore delivered to us, you reserve the right to withhold the above-mentioned concession to dealers on such Securities if sold to us at the public offering price, or if such concession has been allowed to us through our purchase at a net price, we agree to repay such concession upon your demand, plus in each case any taxes on redelivery, commissions, accrued interest and dividends paid in connection with such purchase or contract to purchase.

(d) Open Market Transactions. We agree not to bid for, purchase, attempt to purchase, or sell, directly or indirectly, any Securities, any other securities of the issuer of the Securities of the same class and series or any other securities of such issuer as you may designate, except as brokers pursuant to unsolicited orders and as otherwise provided in this Agreement. If the Securities are common stock or securities convertible into common stock, we agree not to effect, or attempt to induce others to effect, directly or indirectly, any transactions in or relating to put or call options on any stock of such issuer, except to the

3

extent permitted by Rule 10b-6 under the Exchange Act as interpreted by the Securities and Exchange Commission. An opening uncovered writing transaction in options to acquire Securities for our account or for the account of any customer shall be deemed, for purposes of the preceding sentence, to be a transaction effected by us in or relating to put or call options on stock of the Company not permitted by Rule 10b-6. The term "opening uncovered writing transaction" means an opening sale transaction where the seller intends to become a writer of an option to purchase stock which it does not own or have the right to acquire upon exercise of conversion or option rights.

(e) NASD. We represent that we are actually engaged in the investment banking or securities business and we are either a member in good standing of the NASD, or, if not such a member, a foreign dealer not eligible for membership. If we are such a member we agree that in making sales of the Securities we will comply with all applicable rules of the NASD, including, without limitation, the NASD's Interpretation with Respect to Fee-Riding and Withholding and Section 24 of Article III of the Rules of Fair Practice. If we are such a foreign dealer, we agree not to offer or sell any Securities in the United States of America except through you and in making sales of Securities outside the United States of America we agree to comply as though we were a member with such Interpretation and Sections 8.24 and 36 of Article III of the NASD's Rules of Fair Practice and to comply with Section 25 of such Article III as it applies to a nonmember broker or dealer in a foreign country.

(f) Relationship among Underwriters and Selected Dealers. You may buy Securities from or sell Securities to any Underwriter or Selected Dealer and, with your consent, the Underwriters (if any) and the Selected Dealers may purchase Securities from and sell Securities to each other at the public offering price less all or any part of the concession. We are not authorized to act as agent for you or any Underwriter or the issuer or other seller of any Securities in offering Securities to the public or otherwise. Nothing contained herein or in any Written Communication from you shall constitute the Selected Dealers partners with you or any Underwriter or with one another. Neither you nor any Underwriter shall be under any obligation to us except for obligations assumed hereby or in any Written Communication from you in connection with any Offering. In connection with any Offering, we agree to pay our proportionate share of any claim, demand or liability asserted against us, and the other Selected Dealers or any of them, or against you or the Underwriters, if any, based on any claim that such Selected Dealers or any of them constitute an association, unincorporated business or other separate entity, including in each case our proportionate share of any expense incurred in defending against any such claim, demand or liability.

(g) Blue Sky Laws. Upon application to you, you will inform us as to the jurisdictions in which you believe the Securities have been qualified for sale under the respective securities of "blue sky" laws of such jurisdictions. We understand and agree that compliance with the securities or "blue sky" laws in each jurisdiction in which we shall offer or sell any of the Securities shall be our sole responsibility and that you assume no responsibility or obligations as to the eligibility of the Securities for sale or our right to sell the Securities in any jurisdiction.

4

(h) Compliance with Law. We agree that in selling Securities pursuant to any Offering (which agreement shall also be for the benefit of the issuer or other seller of such Securities) we will comply with the applicable provisions of the Securities Act and the Exchange Act, the applicable rules and regulations of the Securities and Exchange Commission thereunder, the applicable rules and regulations of the NASD and the applicable rules and regulations of any securities exchange having jurisdiction over the Offering. You shall have full authority to take such action as you may deem advisable in respect of all matters pertaining to any Offering. Neither you nor any Underwriter shall be under any liability to us, except for lack of good faith and for obligations expressly assumed by you in this Agreement; provided, however, that nothing in this sentence shall be deemed to relieve you from any liability imposed by the Securities Act.

4. Termination; Supplements and Amendments. This agreement may be terminated by either party hereto upon five business days' written notice to the other party; provided that with respect to any Offering for which a Written Communication was sent and accepted prior to such notice, this Agreement as it applies to such Offering shall remain in full force and effect and shall terminate with respect to such Offering in accordance with the last sentence of this Section. This Agreement may be supplemented or amended by you by written notice thereof to us, and any such supplement or amendment to this Agreement shall be effective with respect to any Offering to which this Agreement applies after the date of such supplement or amendment. Each reference to "this Agreement" herein shall, as appropriate, be to this Agreement as so amended and supplemented. The terms and conditions set forth in Sections 3(b) and (d) with regard to any Offering will terminate at the close of business on the thirtieth day after the date of the initial public offering of the Securities to which such Offering relates, but such terms and conditions, upon notice to us, may be terminated by you at any time.

5. Successors and Assigns. This Agreement shall be binding on, and inure to the benefit of, the parties hereto and other persons specified or indicated in Section 1, and the respective successors and assigns of each of them.

6. Governing Law. This Agreement and the terms and conditions set forth herein with respect to any Offering together with such supplementary terms and conditions with respect to such Offering as may be contained in any Written Communication from you to us in connection therewith shall be governed by, and construed in accordance with, the laws of the State of New York.

By signing this Agreement we confirm that our subscription to, or our acceptance of any reservation of, any Securities pursuant to an Offering shall constitute (i) acceptance of and agreement to other terms and conditions of this Agreement (as supplemented and amended pursuant to Section 4) together with and subject to any supplementary terms and conditions contained in any Written Communication from you in connection with such Offering, all of which shall constitute a binding agreement between us and you, individually or as representative of any Underwriters, (ii) confirmation that our representations and warranties set forth in Section 3 are true and correct at that time and
(iii) confirmation that

5

our agreements set forth in Sections 2 and 3 have been and will be fully performed by us to the extent and at the times required thereby.

Very truly yours,

MASTER CUSTODIAN AGREEMENT

This Agreement is made between each investment company advised by Eaton Vance Management which has adopted this Agreement in the manner provided herein and Investors Bank & Trust Company (hereinafter called "Bank", "Custodian" and "Agent"), a trust company established under the laws of Massachusetts with a principal place of business in Boston, Massachusetts.

Whereas, each such investment company is registered under the Investment Company Act of 1940 and has appointed the Bank to act as Custodian of its property and to perform certain duties as its Agent, as more fully hereinafter set forth; and

Whereas, the Bank is willing and able to act as each such investment company's Custodian and Agent, subject to and in accordance with the provisions hereof;

Now, therefore, in consideration of the premises and of the mutual covenants and agreements herein contained, each such investment company and the Bank agree as follows:

1. DEFINITIONS

Whenever used in this Agreement, the following words and phrases, unless the context otherwise requires, shall have the following meanings:

(a) "Fund" shall mean the investment company which has adopted this Agreement. If the Fund is a Massachusetts business trust, it may in the future establish and designate other separate and distinct series of shares, each of which may be called a "portfolio"; in such case, the term "Fund" shall also refer to each such separate series or portfolio.

(b) "Board" shall mean the board of directors/trustees/managing general partners/director general partners of the Fund, as the case may be.

(c) "The Depository Trust Company", a clearing agency registered with the Securities and Exchange Commission under Section 17A of the Securities Exchange Act of 1934 which acts as a securities depository and which has been specifically approved as a securities depository for the Fund by the Board.

(d) "Participants Trust Company", a clearing agency registered with the Securities and Exchange Commission under Section 17A of the Securities Exchange Act of 1934 which acts as a securities depository and which has been specifically approved as a securities depository for the Fund by the Board.

(e) "Approved Clearing Agency" shall mean any other domestic clearing agency registered with the Securities and Exchange Commission under Section 17A of the Securities Exchange Act of 1934 which acts as a securities depository BUT ONLY if the Custodian has received a certified copy of a vote of the Board approving such clearing agency as a securities depository for the Fund.

(f) "Federal Book-Entry System" shall mean the book-entry system referred to in Rule 17f-4(b) under the Investment Company Act of 1940 for United States and federal agency securities (i.e., as provided in Subpart O of Treasury Circular No. 300, 31 CFR 306, Subpart B of 31 CFR Part 350, and the book-entry regulations of federal agencies substantially in the form of Subpart O).

(i) The Custodian shall be deemed to have received "proper instructions" in respect of any of the matters referred to in this Agreement upon receipt of written or facsimile instructions signed by such one or more person or persons as the Board shall have from time to time authorized to give the particular class of instructions in question. Electronic instructions for the purchase and sale of securities which are transmitted by Eaton Vance Management to the Custodian through the Eaton Vance equity trading system and the Eaton Vance fixed income trading system shall be deemed to be proper instructions; the Fund shall cause all such instructions to be confirmed in writing. Different persons may be authorized to give instructions for different purposes. A certified copy of a vote of the Board may be received and accepted by the Custodian as conclusive evidence of the authority of any such person to act and may be considered as in full force and effect until receipt of written notice to the contrary. Such instructions may be general or specific in terms and, where appropriate, may be standing instructions. Unless the vote delegating authority to any person or persons to give a particular class of instructions specifically requires that the approval of any person, persons or committee shall first have been obtained before the Custodian may act on instructions of that class, the Custodian shall be under no obligation to question the right of the person or persons giving such instructions in so doing. Oral instructions will be considered proper instructions if the Custodian reasonably believes them to have been given by a person authorized to give such instructions with respect to the transaction involved. The Fund shall cause all oral instructions to be confirmed in writing. The Fund authorizes the Custodian to tape record any and all telephonic or other oral instructions given to the Custodian. Upon receipt of a certificate signed by two officers of the Fund as to the authorization by the President and the Treasurer of the Fund accompanied by a detailed description of the communication procedures approved by the President and the Treasurer of the Fund, "proper instructions" may also include communications effected directly between electromechanical or electronic devices provided that the President and Treasurer of the Fund and the Custodian are satisfied that such procedures afford adequate safeguards for the Fund's assets. In performing its duties generally, and more particularly in connection with the purchase, sale and exchange of securities made by or for the Fund, the Custodian may take cognizance of the provisions of the governing documents and registration statement of the Fund as the same may from time to time be in effect (and votes, resolutions or proceedings of the shareholders or the Board), but, nevertheless, except as otherwise expressly provided herein, the Custodian may assume unless and until notified in writing to the contrary that so-called proper instructions received by it are not in conflict with or in any way contrary to any provisions of such governing documents and registration statement, or votes, resolutions or proceedings of the shareholders or the Board.

The Administrator hereby accepts such employment, and agrees to administer the Fund's business affairs and, in connection therewith, to furnish for the use of the Fund office space and all necessary office facilities, equipment and personnel for administering the affairs of the Fund. The Administrator shall also pay the salaries and compensation of all officers and Trustees of the Fund who are members of the Administrator's organization and who render executive and administrative services to the Fund, and the salaries and compensation of all other personnel of the Administrator performing management and administrative services for the Fund.

(iv) will arrange for the filing with the appropriate authorities all required federal, state and local tax returns; (v) will arrange for the dissemination to shareholders of the Fund's proxy materials, and will oversee the tabulation of proxies by the Fund's transfer agent; (vi) will review and supervise the provision of custodian services to the Fund; and make such reports and recommendations to the Trustees concerning the provision of such services as the Trustees deem appropriate; (vii) will value all such portfolio investments and other assets of the Fund as may be designated by the Trustees (subject to any guidelines, directions and instructions of the Trustees), and review and supervise the calculation of the net asset value of the Fund's shares by the custodian; (viii) will negotiate the terms and conditions under which transfer agency and dividend disbursing services will be provided to the Fund, and the fees to be paid by the Fund in connection therewith; review and supervise the provision of transfer agency and dividend disbursing services to the Fund; and make such reports and recommendations to the Trustees concerning the performance

Sub-Administrators. The Administrator may employ one or more sub-administrators from time to time to perform such of the acts and services of the Administrator and upon such terms and conditions as may be agreed upon between the Administrator and such sub-administrators and approved by the Trustees of the Fund.

2. Compensation of the Administrator.

6. Duration and Termination of this Agreement. This Agreement shall become effective upon the date of its execution, and, unless terminated as herein provided, shall remain in full force and effect through and including February 28, 2000 and shall continue in full force and effect indefinitely thereafter, but only so long as such continuance after February 28, 2000 is specifically approved at least annually (i) by the Board of Trustees of the Fund, and (ii) by the vote of a majority of those Trustees of the Fund who are not interested persons of the Administrator or the Fund.


4

Either party hereto may, at any time on sixty (60) days' prior written notice to the other, terminate this Agreement by action of the Trustees of the Fund or the trustees of the Administrator, and the Fund may, at any time upon such written notice to the Administrator, terminate the Agreement by vote of a majority of the outstanding voting securities of the Fund. This Agreement shall terminate automatically in the event of its assignment.

7. Amendments of the Agreement. This Agreement may be amended by a writing signed by both parties hereto, provided that no amendment to this Agreement shall be effective until approved (i) by the vote of a majority of those Trustees of the Fund who are not interested persons of the Administrator or the Fund, and (ii) by vote of the Board of Trustees of the Fund.

8. Limitation of Liability. Each party expressly acknowledges the provision in the other party's Agreement and Declaration of Trust limiting the personal liability of its shareholders officers, and Trustees, and each party hereby agrees that it shall have recourse to the other party for payment of claims or obligations as between the Fund and the Administrator arising out of this Agreement and shall not seek satisfaction from the Trustees, officers or shareholders of the other party.

The Administrator hereby consents to the use by the Fund of the name "Eaton Vance" as part of the Fund's name; provided, however, that such consent shall be conditioned upon the employment of the Administrator or one of its affiliates as the administrator of the Fund. The name "Eaton Vance" or any variation thereof may be used from time to time in other connections and for other purposes by the Administrator and its affiliates and other investment companies that have obtained consent to the use of the name "Eaton Vance." The Administrator shall have the right to require the Fund to cease using the name "Eaton Vance" as part of the Fund's name if the Fund ceases, for any reason, to employ the Administrator or one of its affiliates as the Fund's administrator. Future names adopted by the Fund for itself, insofar as such names include identifying words requiring the consent of the Administrator, shall be the property of the Administrator and shall be subject to the same terms and conditions.

10. Certain Definitions. The terms "assignment" and "interested persons" when used herein shall have the respective meanings specified in the Investment Company Act of 1940 as now in effect or as hereafter amended subject, however, to such exemptions as may be granted by the Securities and Exchange Commission by any rule, regulation or order. The term "vote of a majority of the outstanding voting securities" shall mean the vote of the lesser of (a) 67 per centum or more of the shares of the Fund present or represented by proxy at the meeting if the holders of more than 50 per centum of the outstanding shares of the Fund are present or represented by proxy at the meeting, or (b) more than 50 per centum of the outstanding shares of the Fund.

FORM OF
SHAREHOLDER SERVICING AGREEMENT

SHAREHOLDER SERVICING AGREEMENT (the "Agreement"), dated as of October 19, 1998, between Eaton Vance Management ("Eaton Vance") and PaineWebber Incorporated ("PaineWebber").

WHEREAS, Eaton Vance Senior Income Trust (the "Trust") is a closed-end, non-diversified management investment company registered under the Investment Company Act of 1940, as amended (the "1940 Act"), and its shares of beneficial interest are registered under the Securities Act of 1933, as amended; and

WHEREAS, Eaton Vance is the investment adviser and the administrator of the Trust; and

WHEREAS, Eaton Vance desires to retain PaineWebber to provide shareholder servicing and market information with respect to the Trust, and PaineWebber is willing to render such services;

NOW, THEREFORE, in consideration of the mutual terms and conditions set forth below, the parties hereto agree as follows:

1. Eaton Vance hereby employs PaineWebber, for the period and on the terms and conditions set forth herein, to provide the following services:

(a) Undertake to make available public information pertaining to the Trust on an ongoing basis and to communicate to investors and prospective investors the Trust's features and benefits (including periodic seminars or conference calls, responses to questions from current or prospective shareholders and specific shareholder contact where appropriate);

(b) Make available to investors and prospective investors market price, net asset value, yield and other information regarding the Trust, if reasonably obtainable, for the purpose of maintaining the visibility of the Trust in the investor community;

(c) At the request of Eaton Vance or the Trust, provide certain economic research and statistical information and reports, if reasonably obtainable, on behalf of Eaton Vance or the Trust and consult with representatives of Eaton Vance and/or Trustees of the Trust in connection therewith, which information and reports shall


include: (i) statistical and financial market information with respect to the Trust's market performance; and (ii) comparative information regarding the Trust and other closed-end management investment companies with respect to (x) the net asset value of their respective shares, (y) the respective market performance of the Trust and such other companies, and (z) other relevant performance indicators; and

(d) At the request of Eaton Vance or the Trust, provide information to and consult with Eaton Vance and/or the Board of Trustees of the Trust 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 Trust, conversion of the Trust 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.

(e) At the request of Eaton Vance or the Trust, PaineWebber shall limit or cease any action or service provided hereunder to the extent and for the time period requested by Eaton Vance or the Trust; provided, however, that pending termination of this Agreement as provided for is Section 5 hereof, any such limitation or cessation shall not relieve Eaton Vance of its payment obligations pursuant to Section 2 hereof.

(f) PaineWebber will promptly notify Eaton Vance or the Trust, as the case may be, if it learns of any material inaccuracy or misstatement in, or material omission from, any written information provided by PaineWebber to Eaton Vance or the Trust in connection with the performance of services by PaineWebber under this Agreement.

2. Eaton Vance will pay PaineWebber a fee computed weekly and payable quarterly at an annualized rate of 0.10% of the average weekly gross assets of the Trust. Gross assets of the Trust shall be calculated by deducting accrued liabilities of the Trust not including the principal amount of any indebtedness of the Trust constituting financial leverage.

3. Eaton Vance acknowledges that the shareholder services of PaineWebber provided for hereunder do not include any advice as to the value of securities or regarding the advisability of purchasing or selling any securities for the Trust's portfolio. No provision of this Agreement shall be considered as creating, nor shall any provision create, any obligation on the part of PaineWebber, and PaineWebber is not hereby agreeing, to: (i) furnish any advice or make any recommendations

2

regarding the purchase or sale of portfolio securities or (ii) render any opinions, valuations or recommendations of any kind or to perform any such similar services in connection with providing the services described in Section 1 hereof.

4. Nothing herein shall be construed as prohibiting PaineWebber or its affiliates from providing similar or other services to any other clients (including other registered investment companies or other investment managers), so long as PaineWebber's services to Eaton Vance and the Trust are not impaired thereby.

5. The term of this Agreement shall commence upon the date referred to above, shall be in effect for a period of two years and shall thereafter continue for successive one year periods provided that the agreement may be terminated by either party upon 60 days' written notice of the intention to terminate.

6. Eaton Vance will furnish PaineWebber with such information as PaineWebber believes appropriate to its assignment hereunder (all such information so furnished being the "Information"). Eaton Vance recognizes and confirms that PaineWebber (a) will use and rely primarily on the Information and on information available from generally recognized public sources in performing the services contemplated by this Agreement without having independently verified the same and (b) does not assume responsibility for the accuracy or completeness of the Information and such other information. To the best of Eaton Vance's knowledge, the Information to be furnished by Eaton Vance when delivered, will be true and correct in all material respects and will not contain any material misstatement of fact or omit to state any material fact necessary to make the statements contained therein not misleading. Eaton Vance will promptly notify PaineWebber if it learns of any material inaccuracy or misstatement in, or material omission from, any Information delivered to PaineWebber.

7. It is understood that PaineWebber is being engaged hereunder solely to provide the services described above to Eaton Vance and to the Trust and that PaineWebber is not acting as an agent or fiduciary of, and shall have no duties or liability to the current or future shareholders of the Trust, the current or future shareholders of the Trust or any other third party in connection with its engagement hereunder, all of which are hereby expressly waived.

8. Eaton Vance agrees that PaineWebber shall have no liability to the Eaton Vance or the Trust for any act or omission to act by PaineWebber in the course of its performance under this Agreement, in the absence of gross negligence or willful misconduct on the part of PaineWebber. Eaton Vance agrees to the indemnifica tion and other agreements set forth in the Indemnification Agreement

3

attached hereto, the provisions of which are incorporated herein by reference and shall survive the termination, expiration or supersession of this Agreement.

9. THIS AGREEMENT SHALL BE CONSTRUED IN ACCOR DANCE WITH THE LAWS OF THE STATE OF NEW YORK FOR CONTRACTS TO BE PERFORMED ENTIRELY THEREIN AND WITHOUT REGARD TO THE CHOICE OF LAW PRINCIPLES THEREOF.

10. EACH OF THE EATON VANCE AND PAINEWEBBER AGREE THAT ANY ACTION OR PROCEEDING BASED HEREON, OR ARISING OUT OF PAINEWEBBER'S ENGAGEMENT HEREUNDER, SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE OF NEW YORK LOCATED IN THE CITY AND COUNTY OF NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK. EATON VANCE AND PAINEWEBBER EACH HEREBY IRREVOCABLY SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK LOCATED IN THE CITY AND COUNTY OF NEW YORK AND OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK FOR THE PURPOSE OF ANY SUCH ACTION OR PROCEEDING AS SET FORTH ABOVE AND IRREVOCABLY AGREE TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH SUCH ACTION OR PROCEEDING.

11. Eaton Vance and PaineWebber each hereby irrevocably waive any right they may have to a trial by jury in respect of any claim based upon or arising out of this Agreement or the transactions contemplated hereby. This Agreement may not be assigned by either party without the prior written consent of the other party.

12. This Agreement (including the attached Indemnification Agreement) embodies the entire agreement and understanding between the parties hereto and supersedes all prior agreements and understandings relating to the subject matter hereof. If any provision of this Agreement is determined to be invalid or unenforceable in any respect, such determination will not affect such provision in any other respect or any other provision of this Agreement, which will remain in full force and effect.

4

PAINEWEBBER INDEMNIFICATION

Date October 19, 1998

Paine Webber Incorporated
1285 Avenue of the Americas
New York, NY 10019

Gentlemen:

In connection with the engagement of Paine Webber Incorporated ("Paine Webber") to advise and assist the undersigned (referred to herein as "we," or "us") with the matters set forth in the Agreement dated October 19, 1998 between us and Paine Webber, we hereby agree to indemnify and hold harmless Paine Webber, its affiliated companies, and each of Paine Webber's and such affiliated companies' respective officers, directors, agents, employees and controlling persons (within the meaning of each of Section 20 of the Securities Exchange Act of 1934 and Section 15 of the Securities Act of 1933) (each of the foregoing, including Paine Webber, being hereinafter referred to as an "Indemnified Person") to the fullest extent permitted by law from and against any and all losses, claims, damages, expenses (including reasonable fees, disbursements and other charges of counsel), actions (including actions brought by us or our equity holders or derivative actions brought by any person claiming through us or in our name), proceedings, arbitrations or investigations (whether formal or informal), or threats thereof (all of the foregoing being hereinafter referred to as "Liabilities"), based upon, relating to or arising out of such engagement or any Indemnified Person's role therein; PROVIDED, HOWEVER, that we shall not be liable under this paragraph: (a) for any amount paid in settlement of claims without our consent, unless our consent is unreasonably withheld, or (b) to the extent that it is finally judicially determined, or expressly stated in an arbitration award, that such Liabilities resulted primarily from the willful misconduct or gross negligence of the Indemnified Person seeking indemnification. If multiple claims are brought against any Indemnified Person in an arbitration or other proceeding and at least one such claim is based upon, relates to or arises out of the engagement of Paine Webber by us or any Indemnified Person's role therein, we agree that any award, judgment and other Liabilities resulting therefrom shall be deemed conclusively to be based on, relate to or arise out of the engagement of Paine Webber by us or any Indemnified Person's role

A-1

therein, except to the extent that such award or judgment expressly states that the award or judgment, or any portion thereof, is based solely upon, relates to or arises out of other matters for which indemnification is not available hereunder. In connection with our obligation to indemnify for expenses as set forth above, we further agree to reimburse each Indemnified Person for all such expenses (including reasonable fees, disbursements and other charges of counsel) as they are incurred by such Indemnified Person; provided, however, that if an Indemnified Person is reimbursed hereunder for any expenses, the amount so paid shall be refunded if and to the extent it is finally judicially determined, or expressly stated in an arbitration award, that the Liabilities in question resulted primarily from the willful misconduct or gross negligence of such Indemnified Person. We hereby also agree that neither Paine Webber nor any other Indemnified Person shall have any liability to us (or anyone claiming through us or in our name) in connection with Paine Webber's engagement by us except to the extent that such Indemnified Person has engaged in willful misconduct or been grossly negligent.

Promptly after Paine Webber receives notice of the commencement of any action or other proceeding in respect of which indemnification or reimbursement may be sought hereunder, Paine Webber will notify us thereof; but the omission so to notify us shall not relieve us from any obligation hereunder unless, and only to the extent that, such omission results in our forfeiture of substantive rights or defenses. If any such action or other proceeding shall be brought against any Indemnified Person, we shall, upon written notice given reasonably promptly following your notice to us of such action or proceeding, be entitled to assume the defense thereof at our expense with counsel chosen by us and reasonably satisfactory to such Indemnified Person; PROVIDED, HOWEVER, that any Indemnified Person may at its own expense retain separate counsel to participate in such defense. Notwithstanding the foregoing, such Indemnified Person shall have the right to employ separate counsel at our expense and to control its own defense of such action or proceeding if, in the reasonable opinion of counsel to such Indemnified Person, (i) there are or may be legal defenses available to such Indemni fied Person or to other Indemnified Persons that are different from or additional to those available to us, or (ii) a difference of position or potential difference of position exists between us and such Indemnified Person that would make such separate representation advisable; PROVIDED, HOWEVER, that in no event shall we be required to pay fees and expenses under this indemnity for more than one firm of attorneys (in addition to local counsel) in any jurisdiction in any one legal action or group of related legal actions. We agree that we will not, without the prior written consent of PaineWebber, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by PaineWebber's engagement (whether or not any Indemnified Person is a party thereto) unless such

A-2

settlement, compromise or consent includes an unconditional release of PaineWebber and each other Indemnified Person from all liability arising or that may arise out of such claim, action or proceeding.

If the indemnification of an Indemnified Person provided for hereunder is finally judicially determined by a court of competent jurisdiction to be unenforceable, then we agree, in lieu of indemnifying such Indemnified Person, to contribute to the amount paid or payable by such Indemnified Person as a result of such Liabilities in such proportion as is appropriate to reflect the relative benefits received, or sought to be received, by us on the one hand and by PaineWebber on the other from transactions in connection with which PaineWebber has been engaged. If the allocation provided in the preceding sentence is not permitted by applicable law, then we agree to contribute to the amount paid or payable by such Indemnified Person as a result of such Liabilities in such proportion as is appropriate to reflect not only the relative benefits referred to in such preceding sentence but also the relative fault of us and of such Indemnified Person. Notwithstanding the foregoing, in no event shall the aggregate amount required to be contributed by all Indemnified Persons taking into account our contributions as described above exceed the amount of fees actually received by PaineWebber pursuant to such engagement. The relative benefits received or sought to be received by us on the one hand and by PaineWebber on the other shall be deemed to be in the same proportion as (a) the total value of the transactions with respect to which PaineWebber has been engaged bears to (b) the fees paid or payable to PaineWebber with respect to such engagement.
