VALUING SHARES

Each Fund values its shares once each day only when the New York Stock Exchange is open for trading (typically Monday through Friday), as of the close of regular trading on the Exchange (normally 4:00 p.m. eastern time). The purchase price of Fund shares is their net asset value (plus a sales charge for Class A shares), which is derived from the value of Fund holdings. When purchasing or redeeming Fund shares, your investment dealer must communicate your order to the principal underwriter by a specific time each day in order for the purchase price or the redemption price to be based on that day's net asset value per share. It is the investment dealer's responsibility to transmit orders promptly. Each Fund may accept purchase and redemption orders as of the time of their receipt by certain investment dealers (or their designated intermediaries).

The Trustees have adopted procedures for valuing investments and have delegated to the investment adviser the daily valuation of such investments. Municipal obligations owned by the Funds are normally valued on the basis of valuations furnished by a pricing service. The pricing service considers various factors relating to bonds and market transactions to determine value. In certain situations, the investment adviser may use the fair value of a security if market prices are unavailable or deemed unreliable. A security that is fair valued may be valued at a price higher or lower than actual market quotations or the value determined by other funds using their own fair valuation procedures. The investment adviser expects to use fair value pricing for municipal obligations under limited circumstances, such as when an obligation is not priced by the pricing service or is in default. Eaton Vance has established a Valuation Committee that oversees the valuation of investments.

PURCHASING SHARES

How to Purchase Shares. You may purchase shares through your investment dealer or by mailing an account application form to the transfer agent (see back cover for address). You may request an account application by calling 1-800-262-1122. Your initial investment must be at least $1,000. A Fund or your investment dealer must receive your purchase order no later than the close of regular trading on the New York Stock Exchange (normally 4:00 p.m. eastern time) in order for your purchase to be effected at that day's net asset value.

After your initial investment, additional investments of $50 or more may be made at any time by sending a check payable to the order of the Fund or the transfer agent directly to the transfer agent (see back cover for address). Please include your name and account number and the name of the Fund and Class of shares with each investment.

You may make automatic investments of $50 or more each month or each quarter from your bank account. You can establish bank automated investing on the account application or by calling 1-800-262-1122. The minimum initial investment amount and Fund policy of redeeming accounts with low account balances are waived for bank automated investing accounts, certain group purchase plans and for persons affiliated with Eaton Vance and its service providers.

If you purchase shares through an investment dealer (which includes brokers, dealers and other financial institutions), that dealer may charge you a fee for executing the purchase for you. Each Fund may suspend the sale of its shares at any time and any purchase order may be refused.

Restrictions on Excessive Trading and Market Timing. The Funds are not intended for excessive trading or market timing. Market timers seek to profit by rapidly switching money into a fund when they expect the share price of the fund to rise and taking money out of the fund when they expect those prices to fall. By realizing profits through short-term trading, shareholders that engage in rapid purchases and sales or exchanges of a fund's shares may dilute the value of shares held by long-term shareholders. Volatility resulting from excessive purchases and sales or exchanges of fund shares, especially involving large dollar amounts, may disrupt efficient portfolio management. In particular, excessive purchases and sales or exchanges of a fund's shares may cause a fund to have difficulty implementing its investment strategies, may force the fund to sell portfolio securities at inopportune times to raise cash or may cause

increased expenses (such as increased brokerage costs, realization of taxable capital gains without attaining any investment advantage or increased administrative costs).

A fund that invests in securities that are, among other things, thinly traded, traded infrequently or relatively illiquid (including certain municipal obligations) is susceptible to the risk that the current market price for such securities may not accurately reflect current market values. A shareholder may seek to engage in short-term trading to take advantage of these pricing differences (commonly referred to as "price arbitrage"). Each Fund has procedures authorizing the investment adviser to use the fair value of a security if market prices are unavailable or deemed unreliable (see "Valuing Shares"). The use of fair value pricing and the restrictions on excessive trading and market timing described below are intended to reduce a shareholder's ability to engage in price arbitrage to the detriment of the Funds.

The Boards of Trustees of the Eaton Vance funds have adopted policies to discourage short-term trading and market timing and to seek to minimize their potentially detrimental effects. Pursuant to these policies, if an investor (through one or more accounts) makes more than two round-trip exchanges (exchanging from one fund to another fund and back again) within 12 months, it will be deemed to constitute market timing or excessive trading. Under the policies, each Fund or its principal underwriter will reject or cancel a purchase order, suspend or terminate the exchange privilege or terminate the ability of an investor to invest in the Eaton Vance funds if the Fund or the principal underwriter determines that a proposed transaction involves market timing or excessive trading that it believes is likely to be detrimental to the Fund. Each Fund and its principal underwriter cannot ensure that they will be able to identify all cases of market timing and excessive trading, although they believe they have adequate procedures in place to attempt to do so. Each Fund or its principal underwriter may also reject or cancel any purchase order (including an exchange) from an investor or group of investors for any other reason. Decisions to reject or cancel purchase orders (including exchanges) in each Fund are inherently subjective and will be made in a manner believed to be in the best interest of a Fund's shareholders. No Eaton Vance fund has any arrangement to permit market timing.

The Funds and the principal underwriter have provided guidance to financial intermediaries (such as banks, broker-dealers, insurance companies and retirement administrators) concerning the application of the Eaton Vance funds' market timing and excessive trading policies to Fund shares held in omnibus accounts maintained and administered by such intermediaries, including guidance concerning situations where market timing or excessive trading is considered to be detrimental to a Fund. Each Fund and the principal underwriter cannot ensure that these financial intermediaries will in all cases apply the policies of the Funds to accounts under their control.

Choosing a Share Class. Each Fund offers different classes of shares. The different classes of shares represent investments in the same portfolio of securities, but the classes are subject to different sales charges and expenses and will likely have different share prices due to differences in class expenses. In choosing the class of shares that suits your investment needs, you should consider:

* how long you expect to own your shares;
* how much you intend to invest;
* the sales charge and total operating expenses associated with owning each class; and
* whether you qualify for a reduction or waiver of any applicable sales charges (see "Reducing or Eliminating Class A Sales Charges" under "Sales Charges" below).

Each investor's considerations are different. You should speak with your investment dealer to help you decide which class of shares is best for you. Set forth below is a brief description of each class of shares offered by the Funds.

Class A shares are offered at net asset value plus a front-end sales charge of up to 4.75%. This charge is deducted from the amount you invest. The Class A sales charge is reduced for purchases of $25,000 or more. The sales charge applicable to your purchase may be reduced under the right of accumulation or a statement of intention, which are described in "Reducing or Eliminating Class A Sales Charges" under "Sales Charges" below. Some investors may be eligible to purchase Class A shares at net asset value under certain circumstances, which are also described below. Class A shares pay service fees equal to 0.20% annually of average daily net assets. Returns on Class A shares are generally higher than returns on Class B shares because Class A has lower annual expenses than that Class.

Class B shares are offered at net asset value with no front-end sales charge. If you sell your Class B shares within six years of purchase, you generally will be subject to a contingent deferred sales charge or "CDSC". The amount of the CDSC applicable to a redemption of Class B shares decreases over six years, as described in the CDSC schedule in "Contingent Deferred Sales Charge" under "Sales Charges" below. The CDSC is deducted from your redemption proceeds. Under certain circumstances, the Class B CDSC may be waived (such as in the case of the death of the shareholder). See "CDSC Waivers" under "Sales Charges" below. Class B shares pay

distribution fees and service fees equal to 0.95% annually of average daily net assets. Returns on Class B shares are generally lower than returns on Class A shares because Class B has higher annual expenses than Class A. Class B shares automatically convert to Class A shares after eight years. Because the sales charge applicable to Class A shares is reduced for larger purchases and Class A has lower operating expenses, purchasing Class B shares may not be appropriate if you are investing a large amount.

Orders for Class B shares of one or more Eaton Vance funds will be refused when the total value of the purchase (including the aggregate value of all Class B shares held within the purchasing shareholder's account) is $100,000 or more. Investors considering cumulative purchases of $100,000 or more, or who, after a purchase of Class B shares, would own shares of Eaton Vance funds with a current market value of $100,000 or more, should consider whether Class A shares would be more advantageous and consult their investment dealer.

Payments to Investment Dealers. In connection with sales of Fund shares, an investment dealer may receive sales charges and Fund distribution and/or service fees as described below. In addition, the principal underwriter, out of its own resources, may make cash payments to certain investment dealers who provide marketing support, transaction processing and/or administrative services and, in some cases, include some or all Eaton Vance funds in preferred or specialized selling programs. Payments made by the principal underwriter to an investment dealer may be significant and are typically in the form of fees based on Fund sales, assets, transactions processed and/or accounts attributable to that investment dealer. Investment dealers also may receive amounts from the principal underwriter in connection with educational or due diligence meetings that include information concerning Eaton Vance funds. The principal underwriter may pay or allow other promotional incentives or payments to investment dealers to the extent permitted by applicable laws and regulations.

Certain investment dealers that maintain "street name" or omnibus accounts provide sub-accounting, recordkeeping and/ or administrative services to the Eaton Vance funds and are compensated for such services by the funds. As used in this prospectus, the term "investment dealer" includes any broker, dealer, bank (including bank trust departments), registered investment adviser, financial planner, retirement plan administrator, their designated intermediaries and any other firm having a selling, administration or similar agreement with the principal underwriter or its affiliates.

* Because the offering price per share is rounded to two decimal places, the actual sales charge you pay on a purchase of Class A shares may be more or less than your total purchase amount multiplied by the applicable sales charge percentage.

** No sales charge is payable at the time of purchase on investments of $1 million or more. A CDSC of 1.00% will be imposed on such investments (as described below) in the event of redemptions within 18 months of purchase.

The principal underwriter will pay an upfront commission of 1.00% to investment dealers on sales of $1 million or more. For Class A share purchases in a single fund in a single transaction totaling $5 million or more, the principal underwriter will pay investment dealers this 1.00% commission monthly in arrears. The rate will be applied to the amount originally invested minus any redemptions (as calculated at month end) and will be paid ratably over the first 18 months after the investment is made.

Reducing or Eliminating Class A Charges. Front-end sales charges on purchases of Class A shares may be reduced under the right of accumulation or under a statement of intention. To receive a reduced sales charge, you must inform your investment dealer or a Fund at the time you purchase shares that you qualify for such a reduction. If you do not let your investment dealer or the Fund know you are eligible for a reduced sales charge, you may not receive the discount to which you are otherwise entitled.

Under the right of accumulation, the sales charge you pay is reduced if the current market value of your holdings in a Fund or any other Eaton Vance fund (based on the current maximum public offering price) plus your new purchase total $25,000 or more. Class A, Advisers Class, Class B, Class C, Class I and/or Class R shares of a Fund or other Eaton Vance funds, as well as shares of Eaton Vance Money Market Fund, owned by you may be included for this purpose. Shares of Eaton Vance Cash Management Fund and Eaton Vance Tax Free Reserves cannot be included under the right of accumulation. Shares owned by you, your spouse and children under age twenty-one may be combined for purposes of the right of accumulation, including shares held for the benefit of any of you in trust or fiduciary accounts (including retirement accounts) or omnibus or "street name" accounts. You may be required to provide documentation to establish your ownership of shares included under the right of accumulation (such as account statements for you, your spouse and children or marriage certificates, birth certificates and/or trust or other fiduciary-related documents).

Under a statement of intention, purchases of $25,000 or more made over a 13-month period are eligible for reduced sales charges. Shares eligible under the right of accumulation may be included to satisfy the amount to be purchased under a statement of intention. Under a statement of intention, the principal underwriter may hold 5% of the dollar amount to be purchased in escrow in the form of shares registered in your name until you satisfy the statement or the 13-month period expires. A statement of intention does not obligate you to purchase (or a Fund to sell) the full amount indicated in the statement.

Class A shares are offered at net asset value (without a sales charge) to clients of financial intermediaries who charge a fee for their services; accounts affiliated with those financial intermediaries; investment and institutional clients of Eaton Vance; certain persons affiliated with Eaton Vance; and certain Eaton Vance and fund service providers. Class A shares may also be purchased at net asset value pursuant to the reinvestment privilege and exchange privilege and when distributions are reinvested. See "Shareholder Account Features" for details.

Contingent Deferred Sales Charge. Each Class of shares is subject to a CDSC on certain redemptions. Class A shares purchased at net asset value in amounts of $1 million or more (other than shares purchased in a single transaction of $5 million or more) are subject to a 1.00% CDSC if redeemed within 18 months of purchase. Investors who purchase Class A shares of a single fund in a single transaction at net asset value in amounts of $5 million or more will not be subject to any CDSC for such investment or any subsequent investment in the same fund. Class B shares are subject to the following CDSC schedule:

Year of Redemption After Purchase CDSC The CDSC is based on the lower of the --------------------------------------- net asset value at the time of

First or Second                     5%    purchase or at the time of redemption.
Third                               4%    Shares acquired through the
Fourth                              3%    reinvestment of distributions are
Fifth                               2%    exempt from the CDSC.  Redemptions are
Sixth                               1%    made first from shares that are not
Seventh or following                0%    subject to a CDSC.

The sales commission payable to investment dealers in connection with sales of Class B shares is described under "Distribution and Service Fees" below.

CDSC Waivers. CDSCs are waived for certain redemptions pursuant to a Withdrawal Plan (see "Shareholder Account Features"). The Class B CDSC is also waived following the death of a beneficial owner of shares (a death certificate and other applicable documents may be required).

Conversion Feature. After eight years, Class B shares automatically convert to Class A shares. Class B shares acquired through the reinvestment of distributions convert in proportion to shares not so acquired.

Distribution and Service Fees. Class B shares have in effect a plan under Rule 12b-1 that allows each Fund to pay distribution fees for the sale and distribution of shares (so-called "12b-1 fees"). Class B shares pay distribution fees to the principal underwriter of 0.75% of average daily net assets annually. Because these fees are paid from Fund assets on an ongoing basis, they will increase your cost over time and may cost you more than paying other types of sales charges. The principal underwriter compensates investment dealers on sales of Class B shares (except exchange transactions and reinvestments) in an amount equal to 4% of the purchase price of the shares.

Both Classes pay service fees for personal and/or account services equal to 0.20% of average daily net assets annually. After the sale of shares, the principal underwriter receives service fees for one year and thereafter

investment dealers generally receive them based on the value of shares sold by such dealers. Although there is no present intention to do so, each Class could pay service fees of up to 0.25% annually upon Trustee approval. Distribution and service fees are subject to the limitations contained in the sales charge rule of the National Association of Securities Dealers, Inc.

More information about sales charges is available free of charge on the Eaton Vance website at www.eatonvance.com and in the Statement of Additional Information. Please consult the Eaton Vance website for any updates to sales charge information before making a purchase of Fund shares.

By Mail               Send your request to the transfer agent along with any
                      certificates and stock powers. The request must be
                      signed exactly as your account is registered and
                      signature guaranteed.  You can obtain a signature
                      guarantee at certain banks, savings and loan
                      institutions, credit unions, securities dealers,
                      securities exchanges, clearing agencies and registered
                      securities associations.  You may be asked to provide
                      additional documents if your shares are registered in
                      the name of a corporation, partnership or fiduciary.

By Telephone          You can redeem up to $100,000 per account (which may
                      include shares of one or more Eaton Vance funds) b y
                      calling the transfer agent at 1-800-262-1122 on Monday
                      through Friday, 9:00 a.m. to 4:00 p.m. (eastern time).
                      Proceeds of a telephone redemption can be mailed only to
                      the account address.  Shares held by corporations,
                      trusts or certain other entities and shares that are
                      subject to fiduciary arrangements cannot be redeemed by
                      telephone.

Through an
Investment Dealer     Your investment dealer is responsible for transmitting
                      the order promptly.  An investment dealer may charge a
                      fee for this service.

If you redeem shares, your redemption price will be based on the net asset value per share next computed after the redemption request is received. Your redemption proceeds will be paid in cash within seven days, reduced by the amount of any applicable CDSC and any federal income tax required to be withheld. Payments will be sent by mail unless you complete the Bank Wire Redemptions section of the account application.

If you recently purchased shares, the proceeds of a redemption will not be sent until the purchase check (including a certified or cashier's check) has cleared. If the purchase check has not cleared, redemption proceeds may be delayed up to 15 days from the purchase date. If your account value falls below $750 (other than due to market decline), you may be asked either to add to your account or redeem it within 60 days. If you take no action, your account will be redeemed and the proceeds sent to you.

While redemption proceeds are normally paid in cash, redemptions may be paid by distributing marketable securities. If you receive securities, you could incur brokerage or other charges in converting the securities to cash.

             this option,  you must obtain a prospectus  of the other fund and
             consider  its  objectives,   risks,   and  charges  and  expenses
             carefully.

Information about the Funds. From time to time, you may be mailed the following:

* Semiannual and annual reports containing a list of portfolio holdings as of the end of the second and fourth fiscal quarters, respectively, performance information and financial statements.
* Periodic account statements, showing recent activity and total share balance.
* Form 1099 and tax information needed to prepare your income tax returns.
* Proxy materials, in the event a shareholder vote is required.
* Special notices about significant events affecting your Fund.

Each Fund will file with the Securities and Exchange Commission ("SEC") a list of its portfolio holdings as of the end of the first and third fiscal quarters on Form N-Q. Each Fund's annual and semiannual reports (as filed on Form N-CSR) and each Form N-Q may be viewed on the SEC's website (www.sec.gov). The most recent fiscal and calendar quarter end holdings may also be viewed on the Eaton Vance website (www.eatonvance.com). Portfolio holdings information is filed with the SEC or posted on the Eaton Vance website approximately 60 days after the end of the quarter to which it relates. Each Fund also posts information about certain portfolio characteristics (such as top ten holdings and asset allocation) as of each calendar quarter end on the Eaton Vance website approximately ten business days after quarter end.

The Eaton Vance funds have established policies and procedures with respect to the disclosure of portfolio holdings and other information concerning Fund characteristics. A description of these policies and procedures is provided in the Statement of Additional Information. Such policies and procedures regarding disclosure of portfolio holdings are designed to prevent the misuse of material, non-public information about the funds.

Withdrawal Plan. You may redeem shares on a regular monthly or quarterly basis by establishing a systematic withdrawal plan. Withdrawals will not be subject to any applicable CDSC if they are, in the aggregate, less than or equal to 12% annually of the greater of either the initial account balance or the current account balance. A minimum account size of $5,000 is required to establish a systematic withdrawal plan. Because purchases of Class A shares are generally subject to an initial sales charge, Class A shareholders should not make withdrawals from their accounts while also making purchases.

Exchange Privilege. You may exchange your Fund shares for shares of the same Class of another Eaton Vance fund or, in the case of Class B shares, Eaton Vance Money Market Fund. Exchanges are made at net asset value. If your shares are subject to a CDSC, the CDSC will continue to apply to your new shares at the same CDSC rate. For purposes of the CDSC, your shares will continue to age from the date of your original purchase of Fund shares.

Before exchanging, you should read the prospectus of the new fund carefully. If you wish to exchange shares, write to the transfer agent (see back cover for address) or call 1-800-262-1122. Periodic automatic exchanges are also available. The exchange privilege may be changed or discontinued at any time. You will receive 60 days' notice of any material change to the privilege. This privilege may not be used for "market timing". If an account (or group of accounts) makes more than two round-trip exchanges (exchanged from one fund to another and back again) within 12 months, it will be deemed to be market timing. As described under "Purchasing Shares", the exchange privilege may be terminated for market timing accounts or for other reasons.

Reinvestment Privilege. If you redeem shares, you may reinvest at net asset value all or any portion of the redemption proceeds in the same class of shares of the Fund you redeem from (or, for Class A shares, in Class A shares of any other Eaton Vance fund), provided that the reinvestment occurs within 60 days of the redemption, and the privilege has not been used more than once in the prior 12 months. Under these circumstances your account will be credited with any CDSC paid in connection with the redemption. Any CDSC period applicable to the shares you acquire upon reinvestment will run from the date of your original share purchase. Reinvestment requests must be in writing. If you reinvest, you will be sold shares at the next determined net asset value following receipt of your request.

Telephone and Electronic Transactions. You can redeem or exchange shares by telephone as described in this prospectus. In addition, certain transactions may be conducted through the Internet. The transfer agent and the principal underwriter have procedures in place to authenticate telephone and electronic instructions (such as using security codes or verifying personal account information). As long as the transfer agent and principal underwriter follow reasonable procedures, they will not be responsible for unauthorized telephone or electronic transactions and you bear the risk of possible loss resulting from these transactions. You may decline the telephone redemption option on the account application. Telephone instructions are tape recorded.

"Street Name" Accounts. If your shares are held in a "street name" account at an investment dealer, that dealer (and not the Fund or its transfer agent) will perform all recordkeeping, transaction processing and distribution payments. Because the Fund will have no record of your transactions, you should contact

your investment dealer to purchase, redeem or exchange shares, to make changes in your account, or to obtain account information. You will not be able to utilize a number of shareholder features, such as telephone transactions, directly with the Fund. The transfer of shares in a "street name" account to an account with another investment dealer or to an account directly with the Fund involves special procedures and you will be required to obtain historical information about your shares prior to the transfer. Before establishing a "street name" account with an investment dealer, you should determine whether that dealer allows reinvestment of distributions in "street name" accounts.

Procedures for Opening New Accounts. To help the government fight the funding of terrorism and money laundering activities, federal law requires each Fund to obtain, verify and record information that identifies each person who opens a Fund account. When you open an account, the transfer agent or your investment dealer will ask you for your name, address, date of birth and other identifying information. You also may be asked to produce a copy of your driver's license and other identifying documents. If a person fails to provide the information requested, any application by that person to open a new account will be rejected. Moreover, if the transfer agent or the investment dealer is unable to verify the identity of a person based on information provided by that person, it may take additional steps including, but not limited to, requesting additional information from the person, closing the person's account or reporting the matter to the appropriate federal authorities. If your account is closed for this reason, your shares may be automatically redeemed. If the Fund's net asset value has decreased since your purchase, you will lose money as a result of this redemption.

Account Questions. If you have any questions about your account or the services available, please call Eaton Vance Shareholder Services at 1-800-262-1122, or write to the transfer agent (see back cover for address).

TAX INFORMATION

Each Fund declares dividends daily and ordinarily pays distributions monthly. Different Classes of a Fund will distribute different dividend amounts. Your account will be credited with dividends beginning on the business day after the day when the funds used to purchase your Fund shares are collected by the transfer agent. For tax purposes, the entire monthly distribution of the Fund's daily dividends ordinarily will constitute tax-exempt income to you. Distributions of any net realized gains will be made once each year (usually in December). A Fund may invest a portion of its assets in securities that generate income that is not exempt from federal income tax. In addition, the exemption of "exempt-interest dividend" income from regular federal income taxation does not necessarily result in similar exemptions from such income under the state or local tax laws. Distributions of any taxable income and net short-term capital gains will be taxable as ordinary income. Distributions of any long-term capital gains are taxable as long-term capital gains. Distributions of interest on certain municipal obligations are a tax preference item under the AMT provisions applicable to individuals and corporations, and all tax-exempt distributions may affect a corporation's AMT liability. Each Fund's distributions will be treated as described above for federal income tax purposes whether they are paid in cash or reinvested in additional shares. A redemption of Fund shares, including an exchange for shares of another fund, is a taxable transaction.

Shareholders, particularly corporations, recipients of social security or railroad retirement benefits and those subject to alternative minimum tax, should consult with their advisers concerning the applicability of state, local and other taxes to an investment. Additional information about state taxes is provided below.

Florida Taxes. The Florida Statutes provide that shares of a Florida fund owned by a Florida resident will be exempt from the Florida intangible personal property tax as long as at least ninety percent (90%) of the net asset value of the portfolio is invested in assets that are exempt from the Florida intangible personal property tax. The Florida Insured Fund will normally invest in tax-exempt obligations of Florida, the United States, the U.S. Territories or political subdivisions of the United States or Florida so Fund shares should, under normal circumstances, be exempt from the Florida intangibles tax.

Hawaii Taxes. In the opinion of special tax counsel to the Hawaii Fund, distributions paid by the Fund will generally be exempt from Hawaii income tax to the extent that they are derived from interest on obligations of the State of Hawaii or any of its political subdivisions or authorities or obligations issued by certain other government authorities (for example, U.S. territories). Distributions derived from the Fund's other investment income and short-term capital gains will be subject to Hawaii income tax as ordinary income and distributions from net realized long-term capital gains will be subject to Hawaii income tax as capital gains.

Capital gains or losses realized from a redemption, sale or exchange of shares of the Fund by a Hawaii resident will be taken into account for Hawaii individual income tax purposes.

Kansas Taxes. In the opinion of special tax counsel to the Kansas Fund, individuals, trusts, estates and corporations will not be subject to the Kansas income tax on the portion of exempt-interest dividends derived from interest on obligations of Kansas and its political subdivisions issued after December 31,

1987, and interest on obligations issued before January 1, 1988 where the laws of the State of Kansas authorizing the issuance of such obligations specifically exempt the interest on such obligations from income tax under the laws of the State of Kansas. All remaining dividends (except for dividends, if any, derived from debt obligations issued by the governments of Puerto Rico, the U.S. Virgin Islands and Guam and which are exempt from federal and state income taxes pursuant to federal law), including dividends derived from capital gains, will be includable in the Kansas taxable income of individuals, trusts, estates and corporations. Distributions treated as long-term capital gains for federal income tax purposes will generally receive the same characterization under Kansas law. Capital gains or losses realized from a redemption, sale or exchange of shares of the Fund by a Kansas taxpayer will be taken into account for Kansas income tax purposes.

The above exemptions do not apply to the privilege tax imposed on banks, banking associations, trust companies, savings and loan associations, and insurance companies, or the franchise tax imposed on corporations. Banks, banking associations, trust companies, savings and loan associations, insurance companies and corporations are urged to consult their own tax advisors regarding the effects of theses taxes before investing in the Fund.

The Kansas Fund has been advised by the Kansas Department of Revenue that dividends derived from shares of the Fund are not subject to the local intangibles tax imposed by counties, cities and townships pursuant to existing Kansas law.

VALUING SHARES

The Fund values its shares once each day only when the New York Stock Exchange is open for trading (typically Monday through Friday), as of the close of regular trading on the Exchange (normally 4:00 p.m. eastern time). The purchase price of Fund shares is their net asset value (plus a sales charge for Class A shares), which is derived from the value of Fund holdings. When purchasing or redeeming Fund shares, your investment dealer must communicate your order to the principal underwriter by a specific time each day in order for the purchase price or the redemption price to be based on that day's net asset value per share. It is the investment dealer's responsibility to transmit orders promptly. The Fund may accept purchase and redemption orders as of the time of their receipt by certain investment dealers (or their designated intermediaries).

The Trustees have adopted procedures for valuing investments and have delegated to the investment adviser the daily valuation of such investments. Municipal obligations owned by the Fund are normally valued on the basis of valuations furnished by a pricing service. The pricing service considers various factors relating to bonds and market transactions to determine value. In certain situations, the investment adviser may use the fair value of a security if market prices are unavailable or deemed unreliable. A security that is fair valued may be valued at a price higher or lower than actual market quotations or the value determined by other funds using their own fair valuation procedures. The investment adviser expects to use fair value pricing for municipal obligations under limited circumstances, such as when an obligation is not priced by the pricing service or is in default. Eaton Vance has established a Valuation Committee that oversees the valuation of investments.

PURCHASING SHARES

HOW TO PURCHASE SHARES. You may purchase shares through your investment dealer or by mailing an account application form to the transfer agent (see back cover for address). You may request an account application by calling 1-800-262-1122. Your initial investment must be at least $1,000. The Fund or your investment dealer must receive your purchase order no later than the close of regular trading on the New York Stock Exchange (normally 4:00 p.m. eastern time) in order for your purchase to be effected at that day's net asset value.

After your initial investment, additional investments of $50 or more may be made at any time by sending a check payable to the order of the Fund or the transfer agent directly to the transfer agent (see back cover for address). Please include your name and account number and the name of the Fund and Class of shares with each investment.

You may make automatic investments of $50 or more each month or each quarter from your bank account. You can establish bank automated investing on the account application or by calling 1-800-262-1122. The minimum initial investment amount and Fund policy of redeeming accounts with low account balances are waived for bank automated investing accounts, certain group purchase plans and for persons affiliated with Eaton Vance and its service providers.

If you purchase shares through an investment dealer (which includes brokers, dealers and other financial institutions), that dealer may charge you a fee for executing the purchase for you. The Fund may suspend the sale of its shares at any time and any purchase order may be refused.

RESTRICTIONS ON EXCESSIVE TRADING AND MARKET TIMING. The Fund is not intended for excessive trading or market timing. Market timers seek to profit by rapidly switching money into a fund when they expect the share price of the fund to rise and taking money out of the fund when they expect those prices to fall. By realizing profits through short-term trading, shareholders that engage in rapid purchases and sales or exchanges of a fund's shares may dilute the value of shares held by long-term shareholders. Volatility resulting from excessive purchases and sales or exchanges of fund shares, especially involving large dollar amounts, may disrupt efficient portfolio management. In particular, excessive purchases and sales or exchanges of a fund's shares may cause a fund to have difficulty implementing its investment strategies, may force the fund to sell portfolio securities at inopportune times to raise cash or may cause increased expenses (such as increased brokerage costs, realization of taxable capital gains without attaining any investment advantage or increased administrative costs).

A fund that invests in securities that are, among other things, thinly traded, traded infrequently or relatively illiquid (including certain municipal obligations) is susceptible to the risk that the current market price for such securities may not accurately reflect current market values. A shareholder may seek to engage in short-term trading to take advantage of these pricing differences (commonly referred to as "price arbitrage"). The Fund has procedures authorizing the investment adviser to use the fair value of a security if market prices are unavailable or deemed unreliable (see "Valuing Shares"). The use of fair value pricing and the restrictions on excessive trading and market timing described below are intended to reduce a shareholder's ability to engage in price arbitrage to the detriment of the Fund.

The Boards of Trustees of the Eaton Vance funds have adopted policies to discourage short-term trading and market timing and to seek to minimize their potentially detrimental effects. Pursuant to these policies, if an investor (through one or more accounts) makes more than two round-trip exchanges (exchanging from one fund to another fund and back again) within 12 months, it will be deemed to constitute market timing or excessive trading. Under the policies, the Fund or its principal underwriter will reject or cancel a purchase order, suspend or terminate the exchange privilege or terminate the ability of an investor to invest in the Eaton Vance funds if the Fund or the principal underwriter determines that a proposed transaction involves market timing or excessive trading that it believes is likely to be detrimental to the Fund. The Fund and its principal underwriter cannot ensure that they will be able to identify all cases of market timing and excessive trading, although they believe they have adequate procedures in place to attempt to do so. The Fund or its principal underwriter may also reject or cancel any purchase order (including an exchange) from an investor or group of investors for any other reason. Decisions to reject or cancel purchase orders (including exchanges) in the Fund are inherently subjective and will be made in a manner believed to be in the best interest of a Fund's shareholders. No Eaton Vance fund has any arrangement to permit market timing.

The Fund and the principal underwriter have provided guidance to financial intermediaries (such as banks, broker-dealers, insurance companies and retirement administrators) concerning the application of the Eaton Vance funds' market timing and excessive trading policies to Fund shares held in omnibus accounts maintained and administered by such intermediaries, including guidance concerning situations where market timing or excessive trading is considered to be detrimental to the Fund. The Fund and the principal underwriter cannot ensure that these financial intermediaries will in all cases apply the policies of the Fund to accounts under their control.

CHOOSING A SHARE CLASS. The Fund offers different classes of shares. The different classes of shares represent investments in the same portfolio of securities, but the classes are subject to different sales charges and expenses and will likely have different share prices due to differences in class expenses. In choosing the class of shares that suits your investment needs, you should consider:

* how long you expect to own your shares;
* how much you intend to invest;
* the sales charge and total operating expenses associated with owning each class; and
* whether you qualify for a reduction or waiver of any applicable sales charges (see "Reducing or Eliminating Class A Sales Charges" under "Sales Charges" below).

Each investor's considerations are different. You should speak with your investment dealer to help you decide which class of shares is best for you. Set forth below is a brief description of each class of shares offered by the Fund.

Class A shares are offered at net asset value plus a front-end sales charge of up to 4.75%. This charge is deducted from the amount you invest. The Class A sales charge is reduced for purchases of $25,000 or more. The sales charge applicable to your purchase may be reduced under the right of accumulation or a statement of intention, which are described in "Reducing or Eliminating Class A Sales Charges" under "Sales Charges" below. Some investors may be eligible to purchase Class A shares at net asset value under certain circumstances, which are also described below. Class A shares pay service fees equal to 0.25% annually of average daily net assets. Returns on Class A shares are generally higher than returns on the Fund's other classes of shares because Class A has lower annual expenses than those classes.

Class B shares are offered at net asset value with no front-end sales charge. If you sell your Class B shares within six years of purchase, you generally will be subject to a contingent deferred sales charge or "CDSC". The amount of the CDSC applicable to a redemption of Class B shares decreases over six years, as described in the CDSC schedule in "Contingent Deferred Sales Charge" under "Sales Charges" below. The CDSC is deducted from your redemption proceeds. Under certain circumstances, the Class B CDSC may be waived (such as in the case of the death of the shareholder). See "CDSC Waivers" under "Sales Charges" below. Class B shares pay distribution fees and service fees equal to 1.00% annually of average daily net assets. Returns on Class B shares are generally lower than returns on Class A shares because Class B has higher annual expenses than Class A. Class B shares will automatically convert to Class A shares after eight years. Because the sales charge applicable to Class A shares is reduced for larger purchases and Class A has lower operating expenses, purchasing Class B shares may not be appropriate if you are investing a large amount.

Orders for Class B shares of one or more Eaton Vance funds will be refused when the total value of the purchase (including the aggregate value of all Class B shares held within the purchasing shareholder's account) is $100,000 or more. Investors considering cumulative purchases of $100,000 or more, or who, after a purchase of Class B shares, would own shares of Eaton Vance funds with a current market value of $100,000 or more, should consider whether Class A shares would be more advantageous and consult their investment dealer.

Class C shares are offered at net asset value with no front-end sales charge. If you sell your Class C shares within one year of purchase, you generally will be subject to a CDSC. The CDSC is deducted from your redemption proceeds. Under certain circumstances, the Class C CDSC may be waived (such as certain redemptions from tax-deferred retirement plan accounts). See "CDSC Waivers" under "Sales Charges" below. Class C shares pay distribution fees and service fees equal to 1.00% annually of average daily net assets. Returns on Class C shares are generally lower than returns on Class A shares because Class C has higher annual expenses than Class A.

Orders for Class C shares of one or more Eaton Vance funds will be refused when the total value of the purchase (including the aggregate value of all Class C shares held within the purchasing shareholder's account) is $1,000,000 or more. Investors considering cumulative purchases of $1,000,000 or more, or who, after a purchase of Class C shares, would own shares of Eaton Vance funds with a current market value of $1,000,000 or more, should consider whether Class A shares would be more advantageous and consult their investment dealer.

PAYMENTS TO INVESTMENT DEALERS. In connection with sales of Fund shares, an investment dealer may receive sales charges and Fund distribution and/or service fees as described below. In addition, the principal underwriter, out of its own resources, may make cash payments to certain investment dealers who provide marketing support, transaction processing and/or administrative services and, in some cases, include some or all Eaton Vance funds in preferred or specialized selling programs. Payments made by the principal underwriter to an investment dealer may be significant and are typically in the form of fees based on Fund sales, assets, transactions processed and/or accounts attributable to that investment dealer. Investment dealers also may receive amounts from the

principal underwriter in connection with educational or due diligence meetings that include information concerning Eaton Vance funds. The principal underwriter may pay or allow other promotional incentives or payments to investment dealers to the extent permitted by applicable laws and regulations.

Certain investment dealers that maintain "street name" or omnibus accounts provide sub-accounting, recordkeeping and/ or administrative services to the Eaton Vance funds and are compensated for such services by the funds. As used in this prospectus, the term "investment dealer" includes any broker, dealer, bank (including bank trust departments), registered investment adviser, financial planner, retirement plan administrator, their designated intermediaries and any other firm having a selling, administration or similar agreement with the principal underwriter or its affiliates.

                                    Sales Charge*        Sales Charge*       Dealer Commission

* Because the offering price per share is rounded to two decimal places, the actual sales charge you pay on a purchase of Class A shares may be more or less than your total purchase amount multiplied by the applicable sales charge percentage. ** No sales charge is payable at the time of purchase on investments of $1 million or more. A CDSC of 1.00% will be imposed on such investments (as described below) in the event of redemptions within 18 months of purchase.

The principal underwriter will pay an upfront commission of 1.00% to investment dealers on sales of $1 million or more. For Class A share purchases in a single fund in a single transaction totaling $5 million or more, the principal underwriter will pay investment dealers this 1.00% commission monthly in arrears. The rate will be applied to the amount originally invested minus any redemptions (as calculated at month end) and will be paid ratably over the first 18 months after the investment is made.

REDUCING OR ELIMINATING CLASS A SALES CHARGES. Front-end sales charges on purchases of Class A shares may be reduced under the right of accumulation or under a statement of intention. To receive a reduced sales charge, you must inform your investment dealer or the Fund at the time you purchase shares that you qualify for such a reduction. If you do not let your investment dealer or the Fund know you are eligible for a reduced sales charge, you may not receive the discount to which you are otherwise entitled.

Under the right of accumulation, the sales charge you pay is reduced if the current market value of your holdings in the Fund or any other Eaton Vance fund (based on the current maximum public offering price) plus your new purchase total $25,000 or more. Class A, Advisers Class, Class B, Class C, Class I and/or Class R shares of the Fund or other Eaton Vance funds, as well as shares of Eaton Vance Money Market Fund, owned by you may be included for this purpose. Shares of Eaton Vance Cash Management Fund and Eaton Vance Tax Free Reserves cannot be included under the right of accumulation. Shares owned by you, your spouse and children under age twenty-one may be combined for purposes of the right of accumulation, including shares held for the benefit of any of you in trust or fiduciary accounts (including retirement accounts) or omnibus or "street name" accounts. You may be required to provide documentation to establish your ownership of shares included under the right of accumulation (such as account statements for you, your spouse and children or marriage certificates, birth certificates and/or trust or other fiduciary-related documents).

Under a statement of intention, purchases of $25,000 or more made over a 13-month period are eligible for reduced sales charges. Shares eligible under the right of accumulation may be included to satisfy the amount to be purchased under a statement of intention. Under a statement of intention, the principal underwriter may hold 5% of the dollar amount to be purchased in escrow in the form of shares registered in your name until you satisfy the statement or the 13-month period expires. A statement of intention does not obligate you to purchase (or the Fund to sell) the full amount indicated in the statement.

Class A shares are offered at net asset value (without a sales charge) to clients of financial intermediaries who charge a fee for their services; accounts affiliated with those financial intermediaries investment and institutional clients of Eaton Vance; certain persons affiliated with Eaton Vance; and certain Eaton Vance and fund service providers. Class A shares may also be purchased at net asset value pursuant to the reinvestment privilege and exchange privilege and when distributions are reinvested. See "Shareholder Account Features" for details.

CONTINGENT DEFERRED SALES CHARGE. Each Class of shares is subject to a CDSC on certain redemptions. Class A shares purchased at net asset value in amounts of $1 million or more (other than shares purchased in a single transaction of $5 million or more) are subject to a 1.00% CDSC if redeemed within 18 months of purchase. Investors who purchase Class A shares of a single fund in a single transaction at net asset value in amounts of $5 million or more will not be subject to any CDSC for such investment or any subsequent investment in the same fund. Class C shares are subject to a 1.00% CDSC if redeemed within 12 months of purchase. Class B shares are subject to the following CDSC schedule:

 Year of Redemption After Purchase       CDSC
-------------------------------------------------
 First or Second                          5%
 Third                                    4%
 Fourth                                   3%
 Fifth                                    2%
 Sixth                                    1%
 Seventh or following                     0%

The CDSC is based on the lower of the net asset value at the time of purchase or at the time of redemption. Shares acquired through the reinvestment of distributions are exempt from the CDSC. Redemptions are made first from shares that are not subject to a CDSC.

The sales commission payable to investment dealers in connection with sales of Class B and Class C shares is described under "Distribution and Service Fees" below.

CDSC WAIVERS. CDSCs are waived for certain redemptions pursuant to a Withdrawal Plan (see "Shareholder Account Features"). The Class B CDSC is also waived following the death of a beneficial owner of shares (a death certificate and other applicable documents may be required).

CONVERSION FEATURE. After eight years, Class B shares automatically convert to Class A shares. Class B shares acquired through the reinvestment of distributions convert in proportion to shares not so acquired.

DISTRIBUTION AND SERVICE FEES. Class B and Class C shares have in effect plans under Rule 12b-1 that allow the Fund to pay distribution fees for the sale and distribution of shares (so-called "12b-1 fees"). Class B and Class C shares pay distribution fees to the principal underwriter of 0.75% of average daily net assets annually. Because these fees are paid from Fund assets on an ongoing basis, they will increase your cost over time and may cost you more than paying other types of sales charges. The principal underwriter compensates investment dealers on sales of Class B and Class C shares (except exchange transactions and reinvestments) in an amount equal to 4% and 1%, respectively, of the purchase price of the shares. After the first year, investment dealers also receive 0.75% of the value of Class C shares in annual distribution fees.

All Classes pay service fees for personal and/or account services equal to 0.25% of average daily net assets annually. After the sale of shares, the principal underwriter receives service fees for one year and thereafter investment dealers generally receive them based on the value of shares sold by such dealers. Distribution and service fees are subject to the limitations contained in the sales charge rule of the National Association of Securities Dealers, Inc.

                    guaranteed.  You can obtain a signature guarantee at certain
                    banks,   savings  and  loan  institutions,   credit  unions,
                    securities dealers, securities exchanges,  clearing agencies
                    and registered securities associations.  You may be asked to
                    provide  additional  documents if your shares are registered
                    in the name of a corporation, partnership or fiduciary.

By  Telephone       You can redeem up to $100,000 per account (which may include
                    shares of one or  more  Eaton  Vance  funds) by calling  the

transfer agent at 1-800-262-1122 on Monday through Friday, 9:00 a.m. to 4:00 p.m. (eastern time). Proceeds of a telephone redemption can be mailed only to the account address. Shares held by corporations, trusts or certain other entities and shares that are subject to fiduciary arrangements cannot be redeemed by telephone.

Through an Your investment dealer is responsible for transmitting the Investment Dealer order promptly. An investment dealer may charge a fee for this service.

If you redeem shares, your redemption price will be based on the net asset value per share next computed after the redemption request is received. Your redemption proceeds will be paid in cash within seven days, reduced by the amount of any applicable CDSC and any federal income tax required to be withheld. Payments will be sent by mail unless you complete the Bank Wire Redemptions section of the account application.

If you recently purchased shares, the proceeds of a redemption will not be sent until the purchase check (including a certified or cashier's check) has cleared. If the purchase check has not cleared, redemption proceeds may be delayed up to 15 days from the purchase date. If your account value falls below $750 (other than due to market decline), you may be asked either to add to your account or redeem it within 60 days. If you take no action, your account will be redeemed and the proceeds sent to you.

While redemption proceeds are normally paid in cash, redemptions may be paid by distributing marketable securities. If you receive securities, you could incur brokerage or other charges in converting the securities to cash.

SHAREHOLDER ACCOUNT FEATURES

Once you purchase shares, the transfer agent establishes a Lifetime Investing Account(R) for you. Share certificates are issued only on request.

DISTRIBUTIONS. You may have your Fund distributions paid in one of the following ways:

* Full Reinvest Option Dividends and capital gains are reinvested in additional shares. This option will be assigned if you do not specify an option.
* Partial Reinvest Option Dividends are paid in cash and capital gains are reinvested in additional shares.
* Cash Option Dividends and capital gains are paid in cash.
* Exchange Option Dividends and/or capital gains are reinvested in additional shares of any class of another Eaton Vance fund chosen by you, subject to the terms of that fund's prospectus. Before selecting this option, you must obtain a prospectus of the other fund and consider its objectives, risks, and charges and expenses carefully.

INFORMATION ABOUT THE FUND. From time to time, you may be mailed the following:

*Semiannual and annual reports containing a list of portfolio holdings as of the end of the second and fourth fiscal quarters, respectively, performance information and financial statements.
*Periodic account statements, showing recent activity and total share balance.
*Form 1099 and tax information needed to prepare your income tax returns. *Proxy materials, in the event a shareholder vote is required. *Special notices about significant events affecting your Fund.

The Fund will file with the Securities and Exchange Commission ("SEC") a list of its portfolio holdings as of the end of the first and third fiscal quarters on Form N-Q. The Fund's annual and semiannual reports (as filed on Form N-CSR) and each Form N-Q may be viewed on the SEC's website (www.sec.gov). The most recent fiscal and calendar quarter end holdings may also be viewed on the Eaton Vance website (www.eatonvance.com). Portfolio holdings information is filed with the SEC or posted on the Eaton Vance website approximately 60 days after the end of the quarter to which it relates. The Fund also posts information about certain portfolio characteristics (such as top ten holdings and asset allocation) as of each calendar quarter end on the Eaton Vance website approximately ten business days after quarter end.

The Eaton Vance funds have established policies and procedures with respect to the disclosure of portfolio holdings and other information concerning Fund characteristics. A description of these policies and procedures is provided in the Statement of Additional Information. Such policies and procedures regarding disclosure of portfolio holdings are designed to prevent the misuse of material, non-public information about the funds.

WITHDRAWAL PLAN. You may redeem shares on a regular monthly or quarterly basis by establishing a systematic withdrawal plan. Withdrawals will not be subject to any applicable CDSC if they are, in the aggregate, less than or equal to 12% annually of the greater of either the initial account balance or the current account balance. A minimum account size of $5,000 is required to establish a systematic withdrawal plan. Because purchases of Class A shares are generally subject to an initial sales charge, Class A shareholders should not make withdrawals from their accounts while also making purchases.

EXCHANGE PRIVILEGE. You may exchange your Fund shares for shares of the same Class of another Eaton Vance fund, or, in the case of Class B and Class C shares, Eaton Vance Money Market Fund. Exchanges are made at net asset value. If your shares are subject to a CDSC, the CDSC will continue to apply to your new shares at the same CDSC rate. For purposes of the CDSC, your shares will continue to age from the date of your original purchase of Fund shares.

Before exchanging, you should read the prospectus of the new fund carefully. If you wish to exchange shares, write to the transfer agent (see back cover for address) or call 1-800-262-1122. Periodic automatic exchanges are also available. The exchange privilege may be changed or discontinued at any time. You will receive 60 days' notice of any material change to the privilege. This privilege may not be used for "market timing". If an account (or group of accounts) makes more than two round-trip exchanges (exchanged from one fund to another and back again) within 12 months, it will be deemed to be market timing. As described under "Purchasing Shares", the exchange privilege may be terminated for market timing accounts or for other reasons.

REINVESTMENT PRIVILEGE. If you redeem shares, you may reinvest at net asset value all or any portion of the redemption proceeds in the same class of shares of the Fund you redeem from (or, for Class A shares, in Class A shares of any other Eaton Vance fund), provided that the reinvestment occurs within 60 days of the redemption, and the privilege has not been used more than once in the prior 12 months. Under these circumstances your account will be credited with any CDSC paid in connection with the redemption. Any CDSC period applicable to the shares you acquire upon reinvestment will run from the date of your original share purchase. Reinvestment requests must be in writing. If you reinvest, you will be sold shares at the next determined net asset value following receipt of your request.

TELEPHONE AND ELECTRONIC TRANSACTIONS. You can redeem or exchange shares by telephone as described in this prospectus. In addition, certain transactions may be conducted through the Internet. The transfer agent and the principal underwriter have procedures in place to authenticate telephone and electronic instructions (such as using security codes or verifying personal account information). As long as the transfer agent and principal underwriter follow reasonable procedures, they will not be responsible for unauthorized telephone or electronic transactions and you bear the risk of possible loss resulting from these transactions. You may decline the telephone redemption option on the account application. Telephone instructions are tape recorded.

"STREET NAME" ACCOUNTS. If your shares are held in a "street name" account at an investment dealer, that dealer (and not the Fund or its transfer agent) will perform all recordkeeping, transaction processing and distribution payments. Because the Fund will have no record of your transactions, you should contact your investment dealer to purchase, redeem or exchange shares, to make changes in your account, or to obtain account information. You will not be able to utilize a number of shareholder features, such as telephone transactions, directly with the Fund. The transfer of shares in a "street name" account to an account with another investment dealer or to an account directly with the Fund involves special procedures and you will be required to obtain historical information about your shares prior to the transfer. Before establishing a "street name" account with an investment dealer, you should determine whether that dealer allows reinvestment of distributions in "street name" accounts.

PROCEDURES FOR OPENING NEW ACCOUNTS. To help the government fight the funding of terrorism and money laundering activities, federal law requires the Fund to obtain, verify and record information that identifies each person who opens a Fund account. When you open an account, the transfer agent or your investment dealer will ask you for your name, address, date of birth and other identifying information. You also may be asked to produce a copy of your driver's license and other identifying documents. If a person fails to provide the information requested, any application by that person to open a new account will be rejected. Moreover, if the transfer agent or the investment dealer is unable to verify the identity of a person based on information provided by that person, it may take additional steps including, but not limited to, requesting additional information from the person, closing the person's account or reporting the matter to the appropriate federal authorities. If your account is closed for this reason, your shares may be automatically redeemed. If the Fund's net asset value has decreased since your purchase, you will lose money as a result of this redemption.

ACCOUNT QUESTIONS. If you have any questions about your account or the services available, please call Eaton Vance Shareholder Services at 1-800-262-1122, or write to the transfer agent (see back cover for address).

TAX INFORMATION

The Fund declares dividends daily and ordinarily pays distributions monthly. Different Classes will distribute different dividend amounts. Your account will be credited with dividends beginning on the business day after the day when the funds used to purchase your Fund shares are collected by the transfer agent. For tax purposes, the entire monthly distribution of the Fund's daily dividends ordinarily will constitute federally tax-exempt income to you. Distribution of any net realized gains will be made once each year (usually in December). The Fund may invest a portion of its assets in securities that generate income that is not exempt from federal income tax. In addition, the exemption of "exempt-interest dividend" income from regular federal income taxation does not necessarily result in similar exemptions from such income under the state or local tax laws.

Distributions of any taxable income and net short-term capital gains will be taxable as ordinary income. Distributions of any long-term capital gains are taxable as long-term capital gains. Distributions of interest on certain municipal obligations are a tax preference item under the AMT provisions applicable to individuals and corporations, and all tax-exempt distributions may affect a corporation's AMT liability. The Fund's distributions will be treated as described above for federal income tax purposes whether they are paid in cash or reinvested in additional shares. A redemption of Fund shares, including an exchange for shares of another fund, is a taxable transaction.

Shareholders, particularly corporations, recipients of social security or railroad retirement benefits and those subject to alternative minimum tax, should consult with their advisers concerning the applicability of state, local and other taxes to an investment.

CALCULATION OF NET ASSET VALUE

The net asset value of each Fund is computed by IBT (as agent and custodian for each Fund) by subtracting the liabilities of the Fund from the value of its total assets. Each Fund will be closed for business and will not price their respective shares on the following business holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Inasmuch as the market for municipal obligations is a dealer market with no central trading location or continuous quotation system, it is not feasible to obtain last transaction prices for most municipal obligations held by a Fund, and such obligations, including those purchased on a when-issued basis, will normally be valued on the basis of valuations furnished by a pricing service. The pricing service uses information with respect to transactions in bonds, quotations from bond dealers, market transactions in comparable securities, various relationships between securities, and yield to maturity in determining value. Taxable obligations for which price quotations are readily available normally will be valued at the mean between the latest available bid and asked prices. Open futures positions on debt securities are valued at the most recent settlement prices, unless such price does not reflect the fair value of the contract, in which case the positions will be valued by or at the direction of the Trustees. Other assets are valued at fair value using methods determined in good faith by or at the direction of the Trustees considering relevant factors, data and information including the market value of freely tradable securities of the same class in the principal market on which such securities are normally traded.

PURCHASING AND REDEEMING SHARES

Additional Information About Purchases. Fund shares are offered for sale only in states where they are registered. Fund shares are continuously offered through investment dealers which have entered into agreements with the principal underwriter. Shares of the Fund are sold at offering price, which is the net asset value plus the initial sales charge, if any. The Fund receives the net asset value. The Fund's principal underwriter receives the sales charge, all or a portion of which may be reallowed to the investment dealers responsible for selling Fund shares. The sales charge table in the prospectus is applicable to purchases of a Fund alone or in combination with purchases of certain other funds offered by the principal underwriter, made at a single time by (i) an individual, or an individual, his or her spouse and their children under the age of twenty-one, purchasing shares for his or their own account, and (ii) a trustee or other fiduciary purchasing shares for a single trust estate or a single fiduciary account. The table is also presently applicable to (1) purchases of Class A shares pursuant to a written Statement of Intention; or (2) purchases of Class A shares pursuant to the Right of Accumulation and declared as such at the time of purchase. See "Sales Charges".

In connection with employee benefit or other continuous group purchase plans, a Fund may accept initial investments of less than $1,000 on the part of an individual participant. In the event a shareholder who is a participant of such a plan terminates participation in the plan, his or her shares will be transferred to a regular individual account. However, such account will be subject to the right of redemption by a Fund as described below.

Suspension of Sales. The Trust may, in its absolute discretion, suspend, discontinue or limit the offering of one or more of its classes of shares at any time. In determining whether any such action should be taken, the Trust's management intends to consider all relevant factors, including (without limitation) the size of a Fund or class, the investment climate and market conditions, the volume of sales and redemptions of shares, and (if applicable) the amount of uncovered distribution charges of the principal underwriter. The Class B Distribution Plan may continue in effect and payments may be made under the Plan following any such suspension, discontinuance or limitation of the offering of shares; however, there is no contractual obligation to continue any Plan for any particular period of time. Suspension of the offering of shares would not, of course, affect a shareholder's ability to redeem shares.

Additional Information About Redemptions. The right to redeem shares of a Fund can be suspended and the payment of the redemption price deferred when the Exchange is closed (other than for customary weekend and holiday closings), during periods when trading on the Exchange is restricted as determined by the SEC, or during any emergency as determined by the SEC which makes it impracticable for a Fund to dispose of its securities or value its assets, or during any other period permitted by order of the SEC for the protection of investors.

Due to the high cost of maintaining small accounts, the Trust reserves the right to redeem accounts with balances of less than $750. Prior to such a redemption, shareholders will be given 60 days' written notice to make an additional purchase. However, no such redemption would be required by the Trust if the cause of the low account balance was a reduction in the net asset value of shares. No CDSC will be imposed with respect to such involuntary redemptions.

While normally payments will be made in cash for redeemed shares, the Trust, subject to compliance with applicable regulations, has reserved the right to pay the redemption price of shares of a Fund, either totally or partially, by a distribution in kind of readily marketable securities. The securities so distributed would be valued pursuant to the valuation procedures described in this SAI. If a shareholder received a distribution in kind, the shareholder could incur brokerage or other charges in converting the securities to cash.

Systematic Withdrawal Plan. The transfer agent will send to the shareholder regular monthly or quarterly payments of any permitted amount designated by the shareholder based upon the value of the shares held. The checks will be drawn from share redemptions and hence, may require the recognition of taxable gain or loss. Income dividends and capital gains distributions in connection with withdrawal plan accounts will be credited at net asset value as of the record date for each distribution. Continued withdrawals in excess of current income will eventually use up principal, particularly in a period of declining market prices. A shareholder may not have a withdrawal plan in effect at the same time he or she has authorized Bank Automated Investing or is otherwise making regular purchases of Fund shares. The shareholder, the transfer agent or the principal underwriter may terminate the withdrawal plan at any time without penalty.

SALES CHARGES

Dealer Commissions. The principal underwriter may, from time to time, at its own expense, provide additional incentives to investment dealers which employ registered representatives who sell Fund shares and/or shares of other funds distributed by the principal underwriter. In some instances, such additional incentives may be offered only to certain investment dealers whose representatives sell or are expected to sell significant amounts of shares. In addition, the principal underwriter may from time to time increase or decrease

the sales commissions payable to investment dealers. The principal underwriter may allow, upon notice to all investment dealers with whom it has agreements, discounts up to the full sales charge during the periods specified in the notice. During periods when the discount includes the full sales charge, such investment dealers may be deemed to be underwriters as that term is defined in the Securities Act of 1933.

Sales Charge Waivers. Class A shares may be sold at net asset value to current and retired Directors and Trustees of Eaton Vance funds and portfolios; to clients (including custodial, agency, advisory and trust accounts) and current and retired officers and employees of Eaton Vance, its affiliates and other investment advisers of Eaton Vance sponsored funds; to officers and employees of IBT and the transfer agent; to persons associated with law firms, consulting firms and others providing services to Eaton Vance and the Eaton Vance funds; and to such persons' spouses, parents, siblings and lineal descendants and their beneficial accounts. Such shares may also be issued at net asset value (1) in connection with the merger (or similar transaction) of an investment company (or series or class thereof) or personal holding company with a Fund (or class thereof), (2) to investors making an investment as part of a fixed fee program whereby an entity unaffiliated with the investment adviser provides multiple investment services, such as management, brokerage and custody, and (3) to investment advisors, financial planners or other intermediaries who place trades for their own accounts or the accounts of their clients and who charge a management, consulting or other fee for their services; clients of such investment advisors, financial planners or other intermediaries who place trades for their own accounts if the accounts are linked to the master account of such investment advisor, financial planner or other intermediary on the books and records of the broker or agent. Class A shares may also be sold at net asset value to registered representatives and employees of investment dealers and bank employees who refer customers to registered representatives of investment dealers. Class A shares are offered at net asset value to the foregoing persons and in the foregoing situations because either (i) there is no sales effort involved in the sale of shares or (ii) the investor is paying a fee (other than the sales charge) to the investment dealer involved in the sale. Any new or revised sales charge or CDSC waiver will be prospective only.

Statement of Intention. If it is anticipated that $25,000 or more of Class A shares and shares of other funds exchangeable for Class A shares of another Eaton Vance fund will be purchased within a 13-month period, the Statement of Intention section of the account application should be completed so that shares may be obtained at the same reduced sales charge as though the total quantity were invested in one lump sum. Shares eligible for the right of accumulation (see below) as of the date of the Statement and purchased during the 13-month period will be included toward the completion of the Statement. If you make a Statement of Intention, the transfer agent is authorized to hold in escrow sufficient shares (5% of the dollar amount specified in the Statement) which can be redeemed to make up any difference in sales charge on the amount intended to be invested and the amount actually invested. A Statement of Intention does not obligate the shareholder to purchase or the Fund to sell the full amount indicated in the Statement.

If the amount actually purchased during the 13-month period is less than that indicated in the Statement, the shareholder will be requested to pay the difference between the sales charge applicable to the shares purchased and the sales charge paid under the Statement of Intention. If the payment is not received in 20 days, the appropriate number of escrowed shares will be redeemed in order to realize such difference. If the total purchases during the 13-month period are large enough to qualify for a lower sales charge than that applicable to the amount specified in the Statement, all transactions will be computed at the expiration date of the Statement to give effect to the lower sales charge. Any difference will be refunded to the shareholder in cash or applied to the purchase of additional shares, as specified by the shareholder. This refund will be made by the investment dealer and the principal underwriter. If at the time of the recomputation, the investment dealer for the account has changed, the adjustment will be made only on those shares purchased through the current investment dealer for the account.

Right of Accumulation. Under the right of accumulation, the applicable sales charge level is calculated by aggregating the dollar amount of the current purchase and the value (calculated at the maximum current offering price) of any Class A, Advisers Class, Class B, Class C, Class I and/or Class R shares of a Fund or other Eaton Vance funds, as well as shares of Eaton Vance Money Market Fund, owned by the shareholder. Shares of Eaton Vance Cash Management Fund and Eaton Vance Tax Free Reserves cannot be accumulated for purposes of this privilege. The sales charge on the shares being purchased will then be applied at the rate applicable to the aggregate. Shares purchased by an individual, his or her spouse and their children under the age of twenty-one, including shares held for the benefit of any such persons in trust or fiduciary accounts (including retirement accounts) or omnibus or "street name" accounts, will be combined for the purpose of determining whether a purchase will qualify for the right of accumulation and if qualifying, the applicable sales charge level. For any such discount to be made available at the time of purchase a purchaser or his or her investment dealer must provide the principal underwriter (in the case of a purchase made through an investment dealer) or the transfer agent (in the case of an investment made by mail) with sufficient information to permit verification that the purchase order qualifies for the accumulation privilege. Confirmation of the order is subject to such verification. The right of accumulation privilege may be amended or terminated at any time as to purchases occurring thereafter.

Conversion Feature. Class B shares held for eight years will automatically convert to Class A shares. For purposes of this conversion, all distributions paid on Class B shares which the shareholder elects to reinvest in Class B shares will be considered to be held in a separate sub-account. Upon the conversion of Class B shares not acquired through the reinvestment of distributions, a pro rata portion of the Class B shares held in the sub-account will also convert to Class A shares. This portion will be determined by the ratio that the Class B shares being converted bears to the total of Class B shares (excluding shares acquired through reinvestment) in the account. This conversion feature is subject to the continuing availability of a ruling from the Internal Revenue Service or an opinion of counsel that the conversion is not taxable for federal income tax purposes.

Exchange Privilege. In addition to exchanges into the same class of another Eaton Vance fund, Class B shares may be exchanged for shares of a money market fund sponsored by an investment dealer and approved by the principal underwriter (an "investment dealer fund"). The CDSC will not be charged to the shareholder when the shares are exchanged for shares of the investment dealer fund, however, the shareholder will receive no credit toward the completion of the CDSC period for the time that the shareholder holds the exchanged shares of the investment dealer fund. If a shareholder redeems the exchanged shares of the investment dealer fund and does not invest the proceeds into Class B shares of an Eaton Vance fund, the shareholder will be subject to any CDSC applicable at the time the shareholder received the exchanged shares of the investment dealer fund.

Distribution and Service Plans

The Trust has in effect a Service Plan (the "Class A Plan") for each Fund's Class A shares that is designed to meet the service fee requirements of the sales charge rule of the NASD. (Management believes service fee payments are not distribution expenses governed by Rule 12b-1 under the 1940 Act, but has chosen to have the Plan approved as if that Rule were applicable.) The Class A Plan provides that Class A shares of each Fund may make service fee payments for personal services and/or the maintenance of shareholder accounts to the principal underwriter, investment dealers and other persons in amounts not exceeding 0.25% of its average daily net assets for any fiscal year. Class A service fees are paid quarterly in arrears. For the service fees paid by Class A shares, see Appendix A.

The Trust also has in effect a compensation-type Distribution Plan (the "Class B Plan") pursuant to Rule 12b-1 under the 1940 Act for each Fund's Class B shares. On each sale of shares (excluding reinvestment of distributions) a Class will pay the principal underwriter amounts representing (i) sales commissions equal to 5% of the amount received by a Fund for each Class share sold and (ii) interest at the rate of 1% over the prime rate then reported in The Wall Street Journal applied to the outstanding amounts owed to the principal underwriter, so-called "uncovered distribution charges". Each Class pays the principal underwriter a distribution fee, accrued daily and paid monthly, at an annual rate not exceeding 0.75% of its average daily net assets to finance the distribution of its shares. Such fees compensate the principal underwriter for the sales commissions paid by it to investment dealers on the sale of shares, for other distribution expenses (such as personnel, overhead, travel, printing and postage) and for interest expenses. The principal underwriter currently pays an up-front sales commission (except on exchange transactions and reinvestments) of 4% of the purchase price of Class B shares. Distribution fees paid by the Class and CDSCs paid to the Fund by redeeming Class shareholders reduce the outstanding uncovered distribution charges of the Class. Whenever there are no outstanding uncovered distribution charges of the Class, the Class discontinues payment of distribution fees.

The Trustees of the Trust believe that each Plan will be a significant factor in the expected growth of each Fund's assets, and will result in increased investment flexibility and advantages which have benefitted and will continue to benefit the Fund and its shareholders. The Eaton Vance organization will profit by reason of the operation of each Class B Plan through an increase in Fund assets and if at any point in time the aggregate amounts received by the principal underwriter pursuant to the Plan and from CDSCs have exceeded the total expenses incurred in distributing Class B shares. Because payments to the principal underwriter under the Class B Plan are limited, uncovered distribution charges (sales expenses of the principal underwriter plus interest, less the above fees and CDSCs received by it) may exist indefinitely. For sales commissions, CDSCs and uncovered distribution charges, see Appendix B.

The Class B Plan also authorizes the payment of service fees to the principal underwriter, investment dealers and other persons in amounts not exceeding 0.25% of its average daily net assets for personal services, and/or the maintenance of shareholder accounts. The Trustees of the Trust have initially implemented this provision of the Class B Plan by authorizing quarterly service fee payments to the principal underwriter and investment dealers in amounts equal to 0.20% of the average daily net assets for any fiscal year which is based on the value of Class B shares sold by such persons. This fee is paid quarterly in arrears based on the value of Class B shares sold by such persons. For the service fees paid, see Appendix B.

The Plans continue in effect from year to year so long as such continuance is approved at least annually by the vote of both a majority of (i) the noninterested Trustees of the Trust who have no direct or indirect financial interest in the operation of the Plan or any agreements related to the Plan (the "Plan Trustees") and (ii) all of the Trustees then in office. Each Plan may be terminated at any time by vote of a majority of the Plan Trustees or by a vote of a majority of the outstanding voting securities of the applicable Class. Each Plan requires quarterly Trustee review of a written report of the amount expended under the Plan and the purposes for which such expenditures were made. The Plans may not be amended to increase materially the payments described therein without approval of the shareholders of the affected Class and the Trustees. So long as a Plan is in effect, the selection and nomination of the noninterested Trustees shall be committed to the discretion of such Trustees. The current Plans were initially approved by the Trustees, including the Plan Trustees, on June 23, 1997. The Trustees of the Trust who are "interested" persons of the Trust have an indirect financial interest in the Plans because their employers (or affiliates thereof) receive distribution and/or service fees under the Plans or agreements related thereto.
