<P STYLE="font: 9pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 6pt">(To Prospectus dated July 23, 2020)</P>

<P STYLE="font: 18pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 0; text-align: center"><B>Eaton Vance National Municipal Opportunities
Trust</B></P>

<P STYLE="font: 14pt Arial, Helvetica, Sans-Serif; margin: 0; text-align: center"><B>Up to 1,142,873 Common Shares</B></P>

<P STYLE="font: 8pt/115% Arial, Helvetica, Sans-Serif; margin: 3pt 0">Important Note. Beginning on January 1, 2021, as permitted
by regulations adopted by the Securities and Exchange Commission, paper copies of the Trust&rsquo;s annual and semi-annual shareholder
reports will no longer be sent by mail unless you specifically request paper copies of the reports. Instead, the reports will be
made available on the Trust&rsquo;s website (funds.eatonvance.com/closed-end-fund-and-term-trust-documents.php), and you will be
notified by mail each time a report is posted and provided with a website address to access the report.</P>

<P STYLE="font: 8pt/115% Arial, Helvetica, Sans-Serif; margin: 3pt 0">If you already elected to receive shareholder reports electronically,
you will not be affected by this change and you need not take any action. If you hold shares at the Trust&rsquo;s transfer agent,
American Stock Transfer &amp; Trust Company, LLC (&ldquo;AST&rdquo;), you may elect to receive shareholder reports and other communications
from the Trust electronically by contacting AST. If you own your shares through a financial intermediary (such as a broker-dealer
or bank), you must contact your financial intermediary to sign up.</P>

<P STYLE="font: 8pt/115% Arial, Helvetica, Sans-Serif; margin: 3pt 0">You may elect to receive all future Trust shareholder reports
in paper free of charge. If you hold shares at AST, you can inform AST that you wish to continue receiving paper copies of your
shareholder reports by calling 1-866-439-6787. If you own these shares through a financial intermediary, you must contact your
financial intermediary or follow instructions included with this disclosure, if applicable, to elect to continue to receive paper
copies of your shareholder reports. Your election to receive reports in paper will apply to all funds held with AST or to all funds
held through your financial intermediary, as applicable.</P>

<P STYLE="font: 9pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 6pt">Eaton Vance National Municipal Opportunities Trust (the &ldquo;Trust,&rdquo;
&ldquo;we,&rdquo; or &ldquo;our&rdquo;) is a diversified, closed-end management investment company which commenced operations on
May 27, 2009. Our primary investment objective is to provide current income exempt from federal income tax. Capital appreciation
is a secondary objective.</P>

<P STYLE="font: 9pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 6pt">The Trust has entered into a distribution agreement dated
November 26, 2019 (the &ldquo;Distribution Agreement&rdquo;) with Eaton Vance Distributors, Inc. (the &ldquo;Distributor&rdquo;)
relating to the common shares of beneficial interest (the &ldquo;Common Shares&rdquo;) offered by this Prospectus Supplement and
the accompanying Prospectus dated July 23, 2020. The Distributor has entered into a dealer agreement, dated November 26, 2019,
(the &ldquo;Dealer Agreement&rdquo;) with UBS Securities LLC (the &ldquo;Dealer&rdquo;) with respect to the Trust relating to the
Common Shares offered by this Prospectus Supplement and the accompanying Prospectus. In accordance with the terms of the Dealer
Agreement, we may offer and sell our Common Shares, $0.01 par value per share, from time to time through the Dealer as sub-placement
agent for the offer and sale of the Common Shares. Under the Investment Company Act of 1940, as amended (the &ldquo;1940 Act&rdquo;),
the Trust may not sell any Common Shares at a price below the current net asset value of such Common Shares, exclusive of any distributing
commission or discount.</P>

<P STYLE="font: 9pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 6pt">Our Common Shares are listed on the New York Stock Exchange
(&ldquo;NYSE&rdquo;) under the symbol &ldquo;EOT.&rdquo; As of July 21, 2020, the last reported sale price for our Common Shares
on the NYSE was $19.88 per share.</P>

<P STYLE="font: 9pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 6pt">Sales of our Common Shares, if any, under this Prospectus
Supplement and the accompanying Prospectus may be made in negotiated transactions or transactions that are deemed to be &ldquo;at
the market&rdquo; as defined in Rule 415 under the Securities Act of 1933, as amended (the &ldquo;1933 Act&rdquo;), including sales
made directly on the NYSE or sales made to or through a market maker other than on an exchange.</P>

<P STYLE="font: 9pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 6pt">The Trust will compensate the Distributor with respect to
sales of the Common Shares at a commission rate of 1.00% of the gross proceeds of the sale of Common Shares. The Distributor will
compensate the Dealer out of this commission at a certain percentage rate of the gross proceeds of the sale of Common Shares sold
under the Dealer Agreement, with the exact amount of such compensation to be mutually agreed upon by the Distributor and the Dealer
from time to time. In connection with the sale of the Common Shares on the Trust&rsquo;s behalf, the Distributor may be deemed
to be an &ldquo;underwriter&rdquo; within the meaning of the 1933 Act and the compensation of the Dealer may be deemed to be underwriting
commissions or discounts.</P>

<P STYLE="font: 9pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 6pt"><B>The Common Shares have traded both at a premium and a discount
to net asset value (&ldquo;NAV&rdquo;).</B> The Trust cannot predict whether Common Shares will trade in the future at a premium
or discount to NAV. The provisions of the 1940 Act generally require that the public offering price of common shares (less any
underwriting commissions and discounts) must equal or exceed the NAV per share of a company&rsquo;s common stock (calculated within
48 hours of pricing). The Trust&rsquo;s issuance of Common Shares may have an adverse effect on prices in the secondary market
for the Trust&rsquo;s Common Shares by increasing the number of Common Shares available, which may put downward pressure on the
market price for the Trust&rsquo;s Common Shares. Shares of common stock of closed-end investment companies frequently trade at
a discount from NAV, which may increase investors&rsquo; risk of loss.</P>

<P STYLE="font: 9pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 6pt"><B>Investing in our securities involves certain risks. You
could lose some or all of your investment. See &ldquo;Investment Objectives, Policies and Risks&rdquo; beginning on page 25 of the
accompanying Prospectus. You should consider carefully these risks together with all of the other information contained in this
Prospectus Supplement and the accompanying Prospectus before making a decision to purchase our securities.</B></P>

<P STYLE="font: 9pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 6pt"><B>Neither the Securities and Exchange Commission nor any
state securities commission has approved or disapproved of these securities or determined if this Prospectus Supplement or the
accompanying Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.</B></P>

reference to the more detailed information included elsewhere in this Prospectus Supplement and in the accompanying Prospectus

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><B>THE TRUST</B></P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Eaton Vance National Municipal Opportunities Trust (the &ldquo;Trust,&rdquo;
&ldquo;we,&rdquo; or &ldquo;our&rdquo;) is a diversified, closed-end management investment company, which commenced operations
on May 27, 2009. The Trust&rsquo;s primary investment objective is to provide current income exempt from federal income tax. Capital
appreciation is a secondary objective. Investments are based on Eaton Vance Management's (&ldquo;Eaton Vance&rdquo; or the &ldquo;Adviser&rdquo;)
research and ongoing credit analysis, the underlying materials which are generally not available to individual investors. An investment
in the Trust may not be appropriate for all investors, and there is no assurance that the Trust will achieve its investment objectives.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><B>THE ADVISER</B></P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Eaton Vance acts as the Trust's investment adviser under an Investment
Advisory and Administrative Agreement (the &ldquo;Advisory Agreement&rdquo;). The Adviser's principal office is located at Two
International Place, 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. As of June 30, 2020, Eaton Vance and its affiliates managed
approximately $486.4 billion of fund and separate account assets on behalf of clients, including 38 open-end and closed-end municipal
bond funds with combined assets of approximately $17.5 billion. 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.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Under the general supervision of the Trust&rsquo;s Board, Eaton
Vance is responsible for managing the Trust's overall investment program, determining the Trust's allocations among its permitted
investments, and selecting individual holdings. The Adviser will furnish to the Trust investment advice and office space and all
necessary office facilities, equipment and personnel for servicing the investments of the Trust and for administering its affairs.
The Adviser will compensate all Trustees and officers of the Trust who are members of the Adviser&rsquo;s organization and will
also compensate all other Adviser personnel who provide research and investment services to the Trust. Pursuant to the Advisory
Agreement, the Trust pays the Adviser a fee calculated as a percentage of the Trust&rsquo;s average daily gross assets in return
for these investment advisory services, facilities and payments. The Trust&rsquo;s advisory fee currently is computed at an annual
rate of 0.60% of the Trust's average daily gross assets up to and including $1.5 billion and 0.59% of average daily gross assets
over $1.5 billion. For purposes of this calculation, &ldquo;gross assets&rdquo; of the Trust shall mean total assets of the Trust,
including any form of investment leverage, minus all accrued expenses incurred in the normal course of operations, but not excluding
any liabilities or obligations attributable to investment leverage obtained through (i) indebtedness of any type (including, without
limitation, borrowing through a credit facility or the issuance of debt securities), (ii) the issuance of preferred stock or other
similar preference securities, (iii) the reinvestment of collateral received for securities loaned in accordance with the Trust&rsquo;s
investment objectives and policies, and/or (iv) any other means, all as determined in accordance with generally accepted accounting
principles.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><B>THE OFFERING</B></P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The Trust has entered into a distribution agreement dated November
26, 2019 (the &ldquo;Distribution Agreement&rdquo;) with Eaton Vance Distributors, Inc. (the &ldquo;Distributor&rdquo;) relating
to the common shares of beneficial interest (the &ldquo;Common Shares&rdquo;), offered by this Prospectus Supplement and the accompanying
Prospectus dated July 23, 2020 (the &ldquo;Offering&rdquo;). The Distributor has entered into a dealer agreement dated November
26, 2019 (the &ldquo;Dealer Agreement&rdquo;) with UBS Securities LLC (the &ldquo;Dealer&rdquo;) with respect to the Trust relating
to the Common Shares offered by this Prospectus Supplement and the accompanying Prospectus. In accordance with the terms of the
Dealer Agreement, the Trust may offer and sell up to 1,142,873 Common Shares, par value $0.01 per Common Share, from time to time
through the Dealer as sub-placement agent for the offer and sale of the Common Shares.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Offerings of the Common Shares will be subject to the provisions
of the 1940 Act, which generally require that the public offering price of common shares of a closed-end investment company (exclusive
of distribution commissions and discounts) must equal or exceed the net asset value per share of the company&rsquo;s common shares
(calculated within 48 hours of pricing), absent shareholder approval or under certain other circumstances.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Sales of the Common Shares, if any, under this Prospectus Supplement
and the accompanying Prospectus may be made in negotiated transactions or transactions that are deemed to be &ldquo;at the market&rdquo;
as defined in Rule 415 under the 1933 Act, including sales made directly on the New York Stock Exchange (&ldquo;NYSE&rdquo;) or
sales made to or through a market maker other than on an exchange. The Common Shares may not be sold through agents, underwriters
or dealers without delivery or deemed delivery of a Prospectus and an accompanying Prospectus Supplement describing the method
and terms of the offering of Common Shares.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><B>LISTING AND SYMBOL</B></P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The Trust&rsquo;s currently outstanding Common Shares are listed
on the NYSE under the symbol &ldquo;EOT.&rdquo; Any new Common Shares offered and sold hereby are expected to be listed on the
NYSE and trade under this symbol. The net asset value of the Common Shares on July 21, 2020 was $21.32 per share. As of July 21,
2020, the last reported sale price for the Common Shares was $19.88.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><B>USE OF PROCEEDS</B></P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The Trust currently intends to invest substantially all of the
net proceeds of any sales of Common Shares pursuant to this Prospectus Supplement in accordance with its investment objectives and
policies as described in the accompanying Prospectus under &ldquo;Investment Objectives, Policies and Risks&rdquo; within three
months of receipt of such proceeds. Such investments may be delayed up to three months if suitable investments are unavailable
at the time or for other reasons, such as market volatility and lack of liquidity in the markets of suitable investments. Pending
such investment, the Trust anticipates that it will invest the proceeds in short-term money market instruments, securities with
remaining maturities of less than one year, cash or cash equivalents. A delay in the anticipated use of proceeds could lower returns
and reduce the Trust&rsquo;s distribution to the holders of Common Shares (&ldquo;Common Shareholders&rdquo;) or result in a distribution
consisting principally of a return of capital.</P>

<P STYLE="font: 12pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><B>Capitalization</B></P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">We may offer and sell up to 1,142,873 of our Common Shares, $0.01
par value per share, from time to time through the Dealer as sub-placement agent under this Prospectus Supplement and the accompanying
Prospectus. Of the 1,142,873 Common Shares, 71,597 have been issued and 1,071,276 are unsold. In addition, the Trust has registered,
and may take down, additional shares at a later date. There is no guarantee that there will be any sales of our Common Shares pursuant
to this Prospectus Supplement and the accompanying Prospectus. The table below assumes that we will sell 1,071,276 Common Shares
at a price of $19.88 per share (the last reported sale price per share of our Common Shares on the NYSE on July 21, 2020). Actual
sales, if any, of our Common Shares under this Prospectus Supplement and the accompanying Prospectus may be greater or less than
$19.88 per share, depending on the market price of our Common Shares at the time of any such sale. To the extent that the market
price per share of our Common Shares on any given day is less than the net asset value per share on such day, we will instruct
the Dealer not to make any sales on such day.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Sales of our Common Shares, if any, under this Prospectus Supplement
and the accompanying Prospectus may be made in negotiated transactions or transactions that are deemed to be &ldquo;at the market&rdquo;
as defined in Rule 415 under the 1933 Act, including sales made directly on the NYSE or sales made to or through a market maker
other than on an exchange. There is no guarantee that there will be any sales of our Common Shares pursuant to this Prospectus
Supplement and the accompanying Prospectus. Actual sales, if any, of our Common Shares under this Prospectus Supplement and the
accompanying Prospectus may be less than as set forth below in this paragraph. In addition, the price per share of any such sale
may be greater or less than the price set forth in this paragraph, depending on the market price of our Common Shares at the time
of any such sale. As a result, the actual net proceeds we receive may be more or less than the amount of net proceeds estimated
in this Prospectus Supplement. Assuming the sale of all of the Common Shares offered under this Prospectus Supplement and the accompanying
Prospectus, at the last reported sale price of $19.88 per share for our Common Shares on the NYSE as of July 21, 2020, we estimate
that the net proceeds of this Offering will be approximately $21,083,997 after deducting the estimated sales load and the estimated
offering expenses payable by the Trust, if any.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Subject to the remainder of this section, the Trust currently
intends to invest substantially all of the net proceeds of any sales of Common Shares pursuant to this Prospectus Supplement in
accordance with its investment objectives and policies as described in the accompanying Prospectus under &ldquo;Investment Objectives,
Policies and Risks&rdquo; within three months of receipt of such proceeds. Such investments may be delayed up to three months if
suitable investments are unavailable at the time or for other reasons, such as market volatility and lack of liquidity in the markets
of suitable investments. Pending such investment, the Trust anticipates that it will invest the proceeds in short-term money market
instruments, securities with remaining maturities of less than one year, cash or cash equivalents. A delay in the anticipated use
of proceeds could lower returns and reduce the Trust&rsquo;s distribution to Common Shareholders or result in a distribution consisting
principally of a return of capital.</P>

upon written instructions from the Distributor, the Dealer will use its reasonable best efforts, to sell, as sub-placement agent,
the Common Shares under the terms and subject to the conditions set forth in the Dealer Agreement. The Dealer&rsquo;s solicitation
will continue until the Distributor instructs the Dealer to suspend the solicitations and offers. The Distributor will instruct
the Dealer as to the amount of Common Shares to be sold by the Dealer. The Distributor may instruct the Dealer not to sell Common
Shares if the sales cannot be effected at or above the price designated by the Distributor in any instruction. To the extent that
the market price per share of the Trust&rsquo;s Common Shares on any given day is less than the net asset value per share on such
day, the Distributor will instruct the Dealer not to make any sales on such day. The Distributor or the Dealer may suspend the
offering of Common Shares upon proper notice and subject to other conditions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The Dealer will provide written confirmation to the Distributor
following the close of trading on the day on which Common Shares are sold under the Dealer Agreement. Each confirmation will include
the number of shares sold on the preceding day, the net proceeds to the Trust and the compensation payable by the Distributor to
the Dealer in connection with the sales.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The Trust will compensate the Distributor with respect to sales
of the Common Shares at a commission rate of 1.00% of the gross proceeds of the sale of Common Shares. The Distributor will compensate
the Dealer for its services in acting as sub-placement agent in the sale of Common Shares out of this commission at a certain percentage
rate of the gross proceeds of the sale of Common Shares sold under the Dealer Agreement, with the exact amount of such compensation
to be mutually agreed upon by the Distributor and the Dealer from time to time. There is no guarantee that there will be any sales
of the Common Shares pursuant to this Prospectus Supplement and the accompanying Prospectus. Actual sales, if any, of the Common
Shares under this Prospectus Supplement and the accompanying Prospectus may be conducted at a price that is greater or less than
the last reported sale price set forth in this Prospectus Supplement, depending on the market price of Common Shares at the time
of any such sale. Eaton Vance will pay the expenses of the Offering (other than the applicable commissions).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Settlement for sales of Common Shares will occur on the second
trading day following the date on which such sales are made, in return for payment of the net proceeds to the Trust. There is no
arrangement for funds to be received in an escrow, trust or similar arrangement.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The Distributor has agreed to provide indemnification and contribution
to the Dealer against certain civil liabilities, including liabilities under the 1933 Act.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The Dealer Agreement will remain in full force and effect unless

Objectives and Policies</B></FONT>. Eaton Vance National Municipal Opportunities Trust (the &#8220;Trust&#8221;) is a diversified,
closed-end management investment company, which commenced operations on May 27, 2009. The Trust&#8217;s primary investment objective
is to provide current income exempt from federal income tax. Capital appreciation is a secondary objective. The Trust will invest
primarily in municipal obligations that, at the time of investment, are investment grade quality. The Trust also may invest a portion
of its assets in municipal obligations rated below investment grade quality or unrated securities that the Trust&#8217;s investment
adviser considers to be of comparable quality. The Trust&#8217;s net asset value (&#8220;NAV&#8221;) and distribution rate will
vary and may be affected by several factors, including changes in interest rates and the credit quality of municipal issuers. Fluctuations
in NAV may be magnified as a result of the Trust&#8217;s use of leverage, which is a speculative investment technique. An investment
in the Trust may not be appropriate for all investors, particularly those that are not subject to federal income tax. There is
no assurance that the Trust will achieve its investment objectives.</P>

Eaton Vance Management (&#8220;Eaton Vance&#8221; or the &#8220;Adviser&#8221;). As of June 30, 2020, Eaton Vance and its affiliates
managed approximately $486.4 billion of fund and separate account assets on behalf of clients, including 38 open-end and closed-end
municipal bond funds with combined assets of approximately $17.5 billion.</P>

Offering.</B></FONT> The Trust may offer, from time to time, in one or more offerings (each, an &#8220;Offering&#8221;), the Trust&#8217;s
common shares of beneficial interest, $0.01 par value (&#8220;Common Shares&#8221;). Common Shares may be offered at prices and
on terms to be set forth in one or more supplements to this Prospectus (each, a &#8220;Prospectus Supplement&#8221;). You should
read this Prospectus and the applicable Prospectus Supplement carefully before you invest in Common Shares. Common Shares may be
offered directly to one or more purchasers, through agents designated from time to time by us, or to or through underwriters or
dealers. The Prospectus Supplement relating to the Offering will identify any agents, underwriters or dealers involved in the offer
or sale of Common Shares, and will set forth any applicable offering price, sales load, fee, commission or discount arrangement
between the Trust and its agents or underwriters, or among its underwriters, or the basis upon which such amount may be calculated,
net proceeds and use of proceeds, and the terms of any sale. The Trust may not sell any Common Shares through agents, underwriters
or dealers without delivery of a Prospectus Supplement describing the method and terms of the particular Offering of the Common
Shares. <FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><I>(continued on inside cover page)</I></FONT></P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>The
Common Shares have traded both at a premium and a discount to NAV</B></FONT>. The Trust cannot predict whether Common Shares will
trade in the future at a premium or discount to NAV. The provisions of the Investment Company Act of 1940, as amended (the &#8220;1940
Act&#8221;), generally require that the public offering price of common shares (less any underwriting commissions and discounts)
must equal or exceed the NAV per share of a company&#8217;s common stock (calculated within 48 hours of pricing). The Trust&#8217;s
issuance of Common Shares may have an adverse effect on prices in the secondary market for the Trust&#8217;s Common Shares by increasing
the number of Common Shares available, which may put downward pressure on the market price for the Trust&#8217;s Common Shares.
Shares of common stock of closed-end investment companies frequently trade at a discount from NAV, which may increase investors&#8217;
risk of loss.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Investing in shares involves certain risks, including
that the Trust will invest substantial portions of its assets in below investment grade quality securities with speculative characteristics.

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Portfolio
Contents</B></FONT>. During normal market conditions, the Trust will invest at least 80% of its gross assets in debt obligations
issued by or on behalf of states, territories and possessions of the United States, including the District of Columbia, and their
political subdivisions, agencies or instrumentalities, the interest on which is exempt from regular federal income tax (&#8220;municipal
obligations&#8221;), including investments in residual interest bonds whose interest is exempt from regular federal income tax.
During normal market conditions, at least 70% of the Trust&#8217;s investments in municipal obligations will be investment grade
quality at the time of investment. Up to 30% of the Trust&#8217;s investments in municipal obligations may be below investment
grade quality at the time of investment. Up to 20% of the Trust&#8217;s investments in municipal obligations may be subject to
the alternative minimum tax.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">A municipal obligation is considered investment grade quality
if it is either (i) rated within the four highest ratings categories by at least one nationally recognized statistical rating organization
(a &#8220;Rating Agency&#8221;), which are those rated Baa or higher by Moody&#8217;s Investors Service, Inc. (&#8220;Moody&#8217;s&#8221;)
or BBB or higher by Standard&nbsp;&amp; Poor&#8217;s Ratings Services (&#8220;S&amp;P&#8221;) or Fitch Ratings (&#8220;Fitch&#8221;),
or (ii) an unrated municipal obligation that the Trust&#8217;s investment adviser considers to be of investment grade quality.
If a municipal obligation is rated differently by two or more Rating Agencies, the Trust will use the higher of such ratings (the
&#8220;Municipal Obligation Rating&#8221;). If a municipal obligation is insured, the Trust will use the higher of the Municipal
Obligation Rating or the insurance issuer&#8217;s rating. Securities rated in the fourth highest category (i.e., Baa by Moody&#8217;s
or BBB by S&amp;P or Fitch) are considered investment grade quality, but may have speculative characteristics. A municipal obligation
is considered below investment grade quality if it is either (i) rated below investment grade by a Rating Agency, or (ii) an unrated
municipal obligation that the Trust&#8217;s investment adviser considers to be of comparable quality. Municipal obligations of
below investment grade quality (commonly referred to as &#8220;junk&#8221; bonds) involve special risks as compared to municipal
obligations of investment grade quality. These risks include greater sensitivity to a general economic downturn, greater market
price volatility and less secondary market trading. The Trust may invest in below investment grade municipal obligations of any
quality. This means that the Trust&#8217;s investments in municipal obligations may include securities of issuers that are having
financial difficulties, which may include being in default on obligations to pay principal or interest thereon when due or involved
in bankruptcy or insolvency proceedings (such securities are commonly referred to as &#8220;distressed securities&#8221;).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Leverage.</B></FONT>
The Trust currently uses leverage to seek to enhance returns by investing in residual interest bonds. The Trust will not utilize
leverage in excess of 15% of its gross assets. Residual interest bonds are securities that pay interest at rates that vary inversely
with changes in prevailing short-term tax-exempt interest rates and provide the economic effect of leverage. Although the Trust
has no current intention to do so, the Trust is authorized also to utilize leverage through the issuance of preferred shares and/or
borrowings, including the issuance of debt securities. The Trust may borrow for temporary, emergency or other purposes as permitted
by the 1940 Act.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Adviser anticipates that the use of leverage (from residual
interest bonds) may result in higher income to holders of Common Shares (&#8220;Common Shareholders&#8221;) 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. The investment advisory fee paid to Eaton Vance will be calculated on the basis of the
Trust&#8217;s average daily gross assets. &#8220;Gross assets&#8221; of the Trust means total assets of the Trust, including assets
attributable to any form of leverage, minus all accrued expenses incurred in the normal course of operations, but not excluding
any liabilities or obligations attributable to leverage obtained through (i) indebtedness of any type (including, without limitation,
borrowing through a credit facility or the issuance of debt securities), (ii) the issuance of preferred stock or other similar
preference securities, (iii) the reinvestment of collateral received for securities loaned in accordance with the Trust&#8217;s
investment objectives and policies, and/or (iv) any other means; all as determined in accordance with generally accepted accounting
principles. This means that the Trust&#8217;s advisory fees will be higher when leverage is utilized which may create an incentive
for the Adviser to employ leverage. In this regard, holders of debt or preferred shares do not bear the investment advisory fee.
Rather, Common Shareholders bear the portion of the investment advisory fee attributable to the assets purchased with the proceeds
from the use of leverage, which means that Common Shareholders effectively bear the entire advisory fee. See &#8220;Investment
Objectives, Policies and Risks &#8211; Use of Leverage and Related Risks&#8221; at page 32, &#8220;Investment Objectives, Policies

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">THE TRUST</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Eaton Vance National Municipal Opportunities Trust (the &#8220;Trust&#8221;)
is a diversified, closed-end management investment company, which commenced operations on May 27, 2009. The Trust&#8217;s investment
objective is to provide current income exempt from federal income tax with capital appreciation as a secondary objective. Investments
are based on the municipal securities research, trading and portfolio management of the Trust&#8217;s investment adviser, Eaton
Vance Management (&#8220;Eaton Vance&#8221; or the &#8220;Adviser&#8221;), which generally are not available to individual investors.
The Trust&#8217;s NAV and distribution rate will vary and may be affected by several factors, including changes in interest rates
and the credit quality of municipal issuers. An investment in the Trust may not be appropriate for all investors, particularly
those that are not subject to federal income tax. There is no assurance that the Trust will achieve its investment objectives.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">THE OFFERING</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may offer, from time to time, in one or more offerings
(each, an &#8220;Offering&#8221;), up to 2,285,745 of the Trust&#8217;s common shares of beneficial interest, $0.01 par value (&#8220;Common
Shares&#8221;), on terms to be determined at the time of the Offering. The Common Shares may be offered at prices and on terms
to be set forth in one or more prospectus supplements. You should read this Prospectus and the applicable Prospectus Supplement
carefully before you invest in Common Shares. Common Shares may be offered directly to one or more purchasers, through agents designated
from time to time by the Trust, or to or through underwriters or dealers. The Prospectus Supplement relating to the Offering will
identify any agents, underwriters or dealers involved in the offer or sale of Common Shares, and will set forth any applicable
offering price, sales load, fee, commission or discount arrangement between the Trust and its agents or underwriters, or among
its underwriters, or the basis upon which such amount may be calculated, net proceeds and use of proceeds, and the terms of any
sale. See &#8220;Plan of Distribution.&#8221; The Trust may not sell any of Common Shares through agents, underwriters or dealers
without delivery of a Prospectus Supplement describing the method and terms of the particular Offering of Common Shares.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">INVESTMENT OBJECTIVES, POLICIES AND RISKS</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Investment
Objectives.</B></FONT> The Trust&#8217;s primary investment objective is to provide current income exempt from federal income tax.
The Trust&#8217;s secondary investment objective is capital appreciation. The Trust will seek to achieve its investment objectives
by investing primarily in municipal obligations (as defined below) that, at the time of investment, are investment grade quality.
The Trust also may invest a portion of its gross assets in municipal obligations rated below investment grade or unrated securities
that the Adviser considers to be of comparable quality. There is no assurance that the Trust will achieve its investment objectives.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Portfolio
Parameters</B></FONT>. During normal market conditions, the Trust will invest at least 80% of its gross assets in debt obligations
issued by or on behalf of states, territories and possessions of the United States, including the District of Columbia, and their
political subdivisions, agencies or instrumentalities, the interest on which is exempt from regular federal income tax (&#8220;municipal
obligations&#8221;). For purposes of this 80% policy, municipal obligations will include investments in residual interest bonds
whose interest is exempt from regular federal income tax.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust&#8217;s investment objectives are considered a non-fundamental
policy that may be changed by the Trust&#8217;s Board of Trustees (the &#8220;Board&#8221;) without approval of the holders of
the Trust&#8217;s common shares (&#8220;Common Shareholder&#8221;). The Trust&#8217;s policy of investing at least 80% of its gross
assets in municipal obligations is considered fundamental and may only be changed upon Common Shareholder approval.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Municipal obligations include bonds, notes and commercial
paper issued by a municipality, a group of municipalities or participants in qualified issues of municipal debt for a wide variety
of both public and private purposes, the interest on which is exempt from regular federal income tax. Public purpose municipal
bonds include general obligation and revenue bonds. Issuers of general obligation bonds include states, counties, cities, towns
and regional districts. The proceeds of these obligations are used to fund a wide range of public projects, including the construction
or improvement of schools, highways and roads, water and sewer systems and a variety of other public purposes. The basic security
of general obligation bonds is the issuer&#8217;s pledge of its faith, credit, and taxing power for the payment of principal and
interest. The taxes that can be levied for the payment of debt service may be limited or unlimited as to rate an amount. Revenue
bonds are backed by the revenues of a project or facility, or from the proceeds of a specific revenue source. Some revenue bonds
are payable solely or partly from funds that are subject to annual appropriations by a state&#8217;s legislature. Municipal notes
include bond anticipation, tax anticipation and revenue anticipation notes. Bond, tax and revenue anticipation notes </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">are short-term obligations that will be retired with the proceeds
of an anticipated bond issue, tax revenue or facility revenue, respectively. Certain types of bonds are issued by or on behalf
of public authorities to finance various privately owned or operated facilities, including certain facilities for the local furnishing
of electric energy or gas, sewage facilities, solid waste disposal facilities and other specialized facilities. The Trust may purchase
municipal obligations in the form of bonds, notes, leases or certificates of participation; structured as callable or non-callable;
with payment forms that include fixed coupon, variable rate, zero-coupon, capital appreciation bonds, residual interest bonds and
short-term floating-rate securities. Such municipal obligations may be acquired through investments in pooled vehicles, partnerships,
or other investment companies. No established resale market exists for certain of the municipal obligations in which the Trust
may invest. The Trust has no limitation on the amount of its assets that may be invested in securities that are not readily marketable
or are subject to restrictions on resale.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">During normal market conditions, at least 70% of the Trust&#8217;s
investments in municipal obligations will be investment grade quality at time of investment. A municipal obligation is considered
investment grade quality if it is either (i) rated within the four highest ratings categories by at least one nationally recognized
statistical rating organization (a &#8220;Rating Agency&#8221;), which are those rated Baa or higher by Moody&#8217;s Investors
Service, Inc. (&#8220;Moody&#8217;s&#8221;) or BBB or higher by Standard &amp; Poor&#8217;s Ratings Services (&#8220;S&amp;P&#8221;)
or Fitch Ratings (&#8220;Fitch&#8221;), or (ii) an unrated municipal obligation that the Trust&#8217;s investment adviser considers
to be of investment grade quality. If a municipal obligation is rated differently by two or more Rating Agencies, the Trust will
use the higher of such ratings (the &#8220;Municipal Obligation Rating&#8221;). If a municipal obligation is insured, the Trust
will use the higher of the Municipal Obligation Rating or the insurance issuer&#8217;s rating. Securities rated in the fourth highest
category (i.e., Baa by Moody&#8217;s or BBB by S&amp;P or Fitch) are considered investment grade quality, but may have speculative
characteristics.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Up to 30% of the Trust&#8217;s investments in municipal obligations
may be below investment grade quality at time of investment. A municipal obligation is considered below investment grade quality
if it is either (i) rated below investment grade by a Rating Agency, or (ii) an unrated municipal obligation that the Trust&#8217;s
investment adviser considers to be of comparable quality. Municipal obligations of below investment grade quality (commonly referred
to as &#8220;junk&#8221; bonds) involve special risks as compared to municipal obligations of investment grade quality. These risks
include greater sensitivity to a general economic downturn, greater market price volatility and less secondary market trading.
The Trust may invest in below investment grade municipal obligations of any quality. This means that the Trust&#8217;s investments
in municipal obligations may include securities of issuers that are having financial difficulties, which may include being in default
on obligations to pay principal or interest thereon when due or involved in bankruptcy or insolvency proceedings (such securities
are commonly referred to as &#8220;distressed securities&#8221;).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Under normal market conditions, the Trust will seek to maintain
an average credit quality of investment grade. As indicated above, the Trust may invest in unrated obligations for which Eaton
Vance will make a credit quality determination for purposes of the Trust&#8217;s credit quality policy. To the extent that the
Trust invests in such unrated obligations, the Trust&#8217;s credit quality will be more dependent on Eaton Vance&#8217;s credit
analysis than if the Trust invested in only rated obligations. For a description of the risks of investing in below investment
grade securities, see &#8220;Investment Objectives, Policies and Risks &#8211; Risk Considerations &#8211; Below Investment Grade
Securities Risk.&#8221;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Up to 20% of the Trust&#8217;s investments in municipal obligations
may be subject to the alternative minimum tax.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Up to 5% of the Trust&#8217;s investments in municipal obligations
may be collateralized by the proceeds from class action or other litigation against the tobacco industry. Such municipal obligations
are backed solely by expected revenues to be derived from lawsuits involving tobacco-related deaths and illnesses which were settled
between certain states and American tobacco companies.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust invests in residual interest bonds, also known as
inverse floating rate securities, which have the economic effect of leverage. A residual interest bond is a type of inverse floating-rate
security created by dividing the income from a municipal bond into two portions. Typically, a third-party sponsor will create a
trust (commonly referred to as a tender option bond trust) consisting of one or more municipal bonds and then create two new securities:
a short-term floating-rate security and a residual interest inverse floating-rate bond. The short-term floating rate security will
be linked to a reference interest rate (such as the London Interbank Offered Rate (&#8220;LIBOR&#8221;) or the Securities Industry
and Financial Markets Association (&#8220;SIFMA&#8221;) Municipal Bond Swap Index), and the tender option bond trust&#8217;s income
will be used to pay the coupon on the short-term floating rate security, with any remaining income going toward the residual interest
bond. Because the residual interest bond is an inverse floating rate security and only pays a residual income, compared to fixed
rate municipal bonds, the value of residual interest bonds will fluctuate to a greater extent in response to changes in prevailing
long-term interest rates. As market interest rates increase, the value of a residual interest bond will decrease. Moreover, the
income earned on such bonds will fluctuate in response to changes in prevailing short-term interest rates. When residual interest
bonds are held by the Trust, an increase in short- or long-term market interest rates may adversely affect the income received

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">LEVERAGE</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust uses leverage in the form of residual interest bonds.
The Trust will not utilize leverage in excess of 15% of its gross assets. Residual interest bonds are residual interests of a special
purpose vehicle (&#8220;SPV&#8221;) that holds municipal obligations. Residual interest bonds pay interest at rates that vary inversely
with changes in prevailing short-term tax-exempt interest rates and provide the economic effect of leverage. The interest rate
payable on a residual interest bond also bears an inverse relationship to the interest rate on floating rate notes issued by the
SPV. Because changes in the interest rate on such floating rate notes inversely affect the interest paid on the residual interest
bond, the value and income of a residual interest bond is generally more volatile than that of a fixed rate bond. Residual interest
bonds have interest rate adjustment formulas that generally reduce or, in the extreme, eliminate the interest paid to the Trust
when short-term interest rates rise, and increase the interest paid to the Trust when short-term interest rates fall. Residual
interest bonds have varying degrees of liquidity, and the market for these securities is relatively volatile. These securities
tend to underperform the market for fixed rate bonds in a rising long-term interest rate environment, but tend to outperform the
market for fixed rate bonds when long-term interest rates decline. Although volatile, residual interest bonds typically offer the
potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality and maturity. While residual
interest bonds expose the Trust to leverage risk because they provide two or more dollars of bond market exposure for every dollar
invested, they are not subject to the Trust&#8217;s restrictions on borrowings. See &#8220;Investment Objectives, Policies and
Risks&#8221; &#8211; Primary Investment Policies &#8211; Residual Interest Bonds.&#8221; Although the Trust has no current intention
to do so, the Trust is also authorized to utilize leverage through the issuance of preferred shares and/or borrowings, including the issuance of debt securities. The Trust
may borrow for temporary, emergency or other purposes as permitted by the 1940 Act.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Eaton Vance believes that the use of leverage (from residual
interest bonds and any borrowings) may result in higher income to holders of Common Shares (&#8220;Common Shareholders&#8221;)
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. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The costs of the financial leverage program (from investment
in residual interest bonds and any borrowings) are borne by Common Shareholders and consequently result in a reduction of the NAV
of Common Shares. The amount of fees paid to Eaton Vance for investment advisory services will be higher if the Trust uses financial
leverage because the fees will be calculated based on the Trust&#8217;s average daily gross assets, which may create a conflict
of interest between Eaton Vance and the Common Shareholders. &#8220;Gross assets&#8221; of the Trust means the total assets of
the Trust, including assets attributable to any form of leverage, minus all accrued expenses incurred in the normal course of operations,
but not excluding any liabilities or obligations attributable to leverage. See &#8220;Investment Objectives, Policies and Risks

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">PLAN OF DISTRIBUTION</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may sell the Common Shares being offered under this
Prospectus in any one or more of the following ways: (i) directly to purchasers; (ii) through agents; (iii) to or through underwriters;
or (iv) through dealers. The Prospectus Supplement relating to the Offering will identify any agents, underwriters or dealers involved
in the offer or sale of Common Shares, and will set forth any applicable offering price, sales load, fee, commission or discount
arrangement between the Trust and its agents or underwriters, or among its underwriters, or the basis upon which such amount may

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may distribute Common Shares from time to time in one
or more transactions at: (i) a fixed price or prices that may be changed; (ii) market prices prevailing at the time of sale; (iii)
prices related to prevailing market prices; or (iv) negotiated prices; provided, however, that in each case the offering price
per Common Share (less any underwriting commission or discount) must equal or exceed the NAV per Common Share.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust from time to time may offer its Common Shares through
or to certain broker-dealers, including UBS Securities LLC, that have entered into selected dealer agreements relating to at-the-market
offerings.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may directly solicit offers to purchase Common Shares,
or the Trust may designate agents to solicit such offers. The Trust will, in a Prospectus Supplement relating to such Offering,
name any agent that could be viewed as an underwriter under the 1933 Act, and describe any commissions the Trust must pay to such
agent(s). Any such agent will be acting on a reasonable best efforts basis for the period of its appointment or, if indicated in
the applicable Prospectus Supplement or other offering materials, on a firm commitment basis. Agents, dealers and underwriters
may be customers of, engage in transactions with, or perform services for the Trust in the ordinary course of business.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">If any underwriters or agents are used in the sale of Common
Shares in respect of which this Prospectus is delivered, the Trust will enter into an underwriting agreement or other agreement
with them at the time of sale to them, and the Trust will set forth in the Prospectus Supplement relating to such Offering their
names and the terms of the Trust&#8217;s agreement with them.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">If a dealer is utilized in the sale of Common Shares in respect
of which this Prospectus is delivered, the Trust will sell such Common Shares to the dealer, as principal. The dealer may then
resell such Common Shares to the public at varying prices to be determined by such dealer at the time of resale.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may engage in at-the-market offerings to or through
a market maker or into an existing trading market, on an exchange or otherwise, in accordance with Rule 415(a)(4) under the 1933
Act. An at-the-market offering may be through an underwriter or underwriters acting as principal or agent for the Trust.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In order to facilitate the Offering of Common Shares, any underwriters
may engage in transactions that stabilize, maintain or otherwise affect the price of Common Shares or any other Common Shares the
prices of which may be used to determine payments on the Common Shares. Specifically, any underwriters may over-allot in connection
with the Offering, creating a short position for their own accounts. In addition, to cover over-allotments or to stabilize the
price of Common Shares or of any such other Common Shares, the underwriters may bid for, and purchase, Common Shares or any such
other Common Shares in the open market. Finally, in any Offering of Common Shares through a syndicate of underwriters, the underwriting
syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing Common Shares in the Offering
if the syndicate repurchases previously distributed Common Shares in transactions to cover syndicate short positions, in stabilization
transactions or otherwise. Any of these activities may stabilize or maintain the market price of Common Shares above independent
market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any
time.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may enter into derivative transactions with third parties,

Supplement indicates, in connection with those derivatives, the third parties may sell Common Shares covered by this Prospectus
and the applicable Prospectus Supplement or other offering materials, including in short sale transactions. If so, the third parties
may use Common Shares pledged by the Trust or borrowed from the Trust or others to settle those sales or to close out any related
open borrowings of securities, and may use Common Shares received from the Trust in settlement of those derivatives to close out
any related open borrowings of securities. The third parties in such sale transactions will be underwriters and, if not identified
in this Prospectus, will be identified in the applicable Prospectus Supplement or other offering materials (or a post-effective

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Any underwriter, agent or dealer utilized in the initial Offering
of Common Shares will not confirm sales to accounts over which it exercises discretionary authority without the prior specific
written approval of its customer.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">DISTRIBUTIONS</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust intends to make regular monthly cash distributions
to Common Shareholders. The amount of each monthly distribution will vary depending on a number of factors, including distributions
payable on any preferred shares or other costs of financial leverage. As portfolio and market conditions change, the rate of distribution
on the Common Shares and the Trust&#8217;s distribution policy could change. Over time, the Trust will distribute all of its net
investment income (after it pays accrued distributions on any outstanding preferred shares or other costs of financial leverage).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The net investment income of the Trust will consist of all interest
income accrued on portfolio investments, short-term capital gain (including short-term gains on options, futures and forward positions
and gains on the sale of portfolio investments held for one year or less) in excess of long-term capital loss and income from certain
hedging transactions, less all expenses of the Trust. Expenses of the Trust will be accrued each day. Substantially all of the
Trust&#8217;s investment company taxable income will be distributed each year. In addition, at least annually, the Trust intends
to distribute any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss). To the
extent that the Trust&#8217;s net investment income and net capital gain for any year exceed the total monthly distributions paid
during the year, the Trust will make a special distribution at or near year-end of such excess amount as may be required. If the
Trust&#8217;s total monthly distributions in any year exceed the amount of its net investment income and net capital gain for the
year, any such excess would be characterized as a return of capital for federal income tax purposes. A return of capital is treated
as a non-dividend distribution for tax purposes and is not subject to current tax. A return of capital reduces a Shareholder&#8217;s
tax cost basis in Trust shares. Under the 1940 Act, for any distribution that includes amounts from sources other than net income,
the Trust is required to provide Common Shareholders a written statement regarding the components of such distribution. Such a
statement will be provided at the time of any distribution believed to include any such amounts.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Common Shareholders may automatically reinvest some or all of
their distributions in additional Common Shares pursuant to the Trust&#8217;s dividend reinvestment plan. See &#8220;Dividend Reinvestment
Plan.&#8221;</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">DIVIDEND REINVESTMENT PLAN</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust has established a dividend reinvestment plan (the &#8220;Plan&#8221;).
Under the Plan, unless a Common Shareholder elects to receive distributions in cash, all distributions will be automatically reinvested
in additional Common Shares. American Stock Transfer &amp; Trust Company, LLC (&#8220;AST&#8221; or the &#8220;Plan Agent&#8221;)
serves as agent for the Common Shareholders in administering the Plan. Common Shareholders who elect not to participate in the
Plan will receive all Trust distributions in cash paid by check mailed directly to the Common Shareholder of record (or, if the
Common Shares are held in street or other nominee name, then to the nominee) by AST, as disbursing agent. Participation in the
Plan is completely voluntary and may be terminated or resumed at any time without penalty by written notice if received by the
Plan Agent prior to any distribution record date. See &#8220;Dividend Reinvestment Plan.&#8221;</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">CLOSED-END STRUCTURE</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">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 NAV
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&#8217;s investment objective(s) 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.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">However, shares of closed-end funds frequently trade at a discount
from their net asset value. Since inception, the market price of the Common Shares has fluctuated and at times traded below the
Trust&#8217;s NAV, and at times has traded above NAV. In recognition of the possibility that the Common Shares might trade at a
discount to net asset value and that any such discount may not be in the interest of Common Shareholders, the Trust&#8217;s Board
of Trustees (the &#8220;Board&#8221;), in consultation with Eaton Vance, from time to time may review possible actions to reduce
any such discount. The Board might consider open market repurchases or tender offers for Common Shares at net asset value. There
can be no assurance that the Board will decide to undertake any of these actions or that, if undertaken, such actions would result
in the Common Shares trading at a price equal to or close to net asset value per Common Share. The Board might also consider the
conversion of the Trust to an open-end management investment company. The Board believes, however, that the closed-end structure
is desirable, given the Trust&#8217;s investment objectives and policies. Investors should assume, therefore, that it is highly
unlikely that the Board would vote to convert the Trust to an open-end management investment company.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">SPECIAL RISK CONSIDERATIONS</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Risk is inherent in all investing. Investing in any investment
company security involves risk, including the risk that you may receive little or no return on your investment or even that you
may lose part or all of your investment.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Discount
From or Premium to NAV</B></FONT>. The Offering will be conducted only when Common Shares of the Trust are trading at a price
equal to or above the Trust&#8217;s NAV per Common Share plus the per Common Share amount of commissions. As with any security,
the market value of the Common Shares may increase or decrease from the amount initially paid for the Common Shares. The Trust&#8217;s
Common Shares have traded both at a premium and at a discount relative to net asset value. The shares of closed-end management
investment companies frequently trade at a discount from their NAV. This is a risk separate and distinct from the risk that the
Trust&#8217;s NAV may decrease.&nbsp;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><B>&nbsp;</B></P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Secondary
Market for the Common Shares</B></FONT>. The issuance of Common Shares through the Offering may have an adverse effect on the secondary
market for the Common Shares. The increase in the amount of the Trust&#8217;s outstanding Common Shares resulting from the Offering
may put downward pressure on the market price for the Common Shares of the Trust. Common Shares will not be issued pursuant to
the Offering at any time when Common Shares are trading at a price lower than a price equal to the Trust&#8217;s NAV per Common
Share plus the per Common Share amount of commissions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust also issues Common Shares of the Trust through its
dividend reinvestment plan. See &#8220;Dividend Reinvestment Plan.&#8221; Common Shares may be issued under the plan at a discount
to the market price for such Common Shares, which may put downward pressure on the market price for Common Shares of the Trust.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">When the Common Shares are trading at a premium, the Trust may
also issue Common Shares of the Trust that are sold through transactions effected on the NYSE. The increase in the amount of the
Trust&#8217;s outstanding Common Shares resulting from that offering may also put downward pressure on the market price for the
Common Shares of the Trust.</P>

Interest rate risk is the risk that the municipal obligations in the Trust&#8217;s portfolio will decline in value because of increases
in market interest rates. Generally, obligations with longer durations or maturities are more sensitive to changes in interest
rates than obligations with shorter durations or maturities, causing them to be more volatile. Conversely, obligations with shorter
durations or maturities will be less volatile but may provide lower returns than obligations with longer durations or maturities.
A decline in the prices of the municipal obligations owned by the Trust would cause a decline in the NAV of the Trust, which could
adversely affect the trading price of the Common Shares. The Trust may utilize certain strategies, including taking positions in
futures or interest rate swaps and forward rate contracts, for the purpose of reducing the interest rate sensitivity of the portfolio
and decreasing the Trust&#8217;s exposure to interest rate risk, although there can be no assurance that it will do so or that
such strategies will be successful.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Because the Trust is managed toward an income objective, it may
hold more longer duration or maturity obligations and thereby be more exposed to interest rate risk than municipal income funds
that are managed with a greater emphasis on total return. Certain factors, such as the presence of call features, may cause a particular
fixed-income security, or the Trust as a whole, to exhibit less sensitivity to changes in interest rates. Certain of the Trust&#8217;s
investments may also be valued, in part, by reference to the relative relationship between interest rates on tax-exempt securities
and taxable securities, respectively. When the market for tax-exempt securities underperforms (or outperforms) the market for taxable
securities, the value of these investments may be negatively affected (or positively affected).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The income investors receive from the Trust is based primarily
on the interest it earns from its investments, which can vary widely over the short- and long-term. If long-term interest rates
drop, investors&#8217; income from the Trust over time could drop as well if the Trust purchases securities with lower interest
coupons.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust invests in residual interest bonds. Compared to similar
fixed-rate municipal bonds, the value of these bonds will fluctuate to a greater extent in response to changes in prevailing long-term
interest rates. Moreover, the income earned on residual interest municipal bonds will fluctuate in response to changes in prevailing
short-term interest rates. Thus, when such bonds are held by the Trust, an increase in short- or long-term market interest rates
may adversely affect the income received from such bonds or the NAV of Trust shares.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Call
and Reinvestment Risks.</B></FONT> If interest rates fall, it is possible that issuers of callable bonds with high interest coupons
will &#8220;call&#8221; (or prepay) their bonds before their maturity date. If a call were exercised by the issuer during a period
of declining interest rates, the Trust would likely replace such called security with a lower yielding security. If that were to
happen, it could decrease the Trust&#8217;s dividends and possibly could affect the market price of Common Shares. Similar risks
exist when the Trust invests the proceeds from matured or traded municipal obligations at market interest rates that are below
the Trust&#8217;s current earnings rate.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Credit
Risk.</B></FONT> Credit risk is the risk that one or more municipal bonds in the Trust&#8217;s portfolio will decline in price,
or fail to pay interest or principal when due, because the issuer of the bond experiences a decline in its financial status. In
general, lower rated municipal bonds carry a greater degree of risk that the issuer will lose its ability to make interest and
principal payments, which could have a negative impact on the Trust&#8217;s NAV or dividends. Securities rated in the fourth highest
category (i.e., Baa by Moody&#8217;s or BBB by S&amp;P or Fitch) are considered investment grade quality, but may have speculative
characteristics. Municipal obligations may be insured as to principal and interest payments. If the claims paying ability or other
rating of the insurer is downgraded by a rating agency, the value of such obligations may be negatively affected. The Trust is
also exposed to credit risk when it engages in certain types of derivatives transactions and when it engages in transactions that
expose the Trust to counterparty risk. See &#8220;Derivatives Risk.&#8221;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Changes in the credit quality of the issuers of municipal
obligations held by the Trust will affect the principal value of (and possibly the income earned on) such obligations. The credit
quality of an issuer of municipal obligations may be affected by a variety of factors, including the issuer&#8217;s tax base, the
extent to which the issuer relies on federal or state aid, limitations on the taxing power of the issuer and changes in general
economic conditions. Changes by Rating Agencies in their ratings of a security and in the ability of the issuer to make payments
of principal and interest may also affect the value of the Trust&#8217;s investments. The amount of information about the financial
condition of an issuer of municipal obligations may not be as extensive as that made available by corporations whose securities
are publicly traded. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In evaluating the quality of a particular instrument, Eaton
Vance may take into consideration, among other things, a credit rating assigned by a credit rating agency, the issuer&#8217;s financial
resources and operating history, its sensitivity to economic conditions and trends, the ability of its management, its debt maturity
schedules and borrowing requirements, and relative values based on anticipated cash flow, interest and asset coverage, and earnings
prospects. Credit rating agencies are private services that provide ratings of the credit quality of certain investments. Credit
ratings issued by rating agencies are based on a number of factors including, but not limited to, the issuer&#8217;s financial
condition and the rating agency&#8217;s credit analysis, if applicable, at the time of rating. As such, the rating assigned to
any particular security is not necessarily a reflection of the issuer&#8217;s current financial condition. The ratings assigned
are not absolute standards of credit quality and do not evaluate market risks or necessarily reflect the issuer&#8217;s current
financial condition or the volatility or liquidity of the security. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">For purposes of determining compliance with the Trust&#8217;s
credit quality restrictions, Eaton Vance relies primarily on the ratings assigned by credit rating agencies but may, in the case
of unrated instruments, perform its own credit and investment analysis to determine an instrument&#8217;s credit quality. A credit
rating may have a modifier (such as plus, minus or a numerical modifier) to denote its relative status within the rating. The presence
of a modifier does not change the security credit rating (for example, BBB- and Baa3 are within the investment grade rating) for
purposes of the Trust&#8217;s investment limitations. If an instrument is rated differently by two or more rating agencies, the
highest rating will be used for purposes of the Trust&#8217;s rating restrictions. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may invest in unrated obligations for which Eaton Vance
will make a credit quality determination for purposes of the Trust&#8217;s credit quality policy. To the extent that the Trust
invests in such unrated obligations, the Trust&#8217;s credit quality will be more dependent on Eaton Vance&#8217;s credit analysis
than if the Trust invested in only rated obligations.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may invest in municipal lease obligations (&#8220;MLOs&#8221;)
and certificates of participation. The obligation of the issuer to meet its obligations under such instruments is often subject
to the ongoing appropriation by a legislative body, on an annual or other basis, of funds for the payment of the obligations. Investments
in municipal leases are thus subject to the risk that the legislative body will not make the necessary appropriation and the issuer
will not otherwise be willing or able to meet its obligation.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Liquidity
Risk.</B></FONT> The secondary market for some municipal obligations is less liquid than that for widely traded taxable debt obligations
or widely traded municipal obligations. No established resale market exists for certain of the municipal obligations in which the
Trust may invest. The Trust has no limitation on the amount of its assets that may be invested in securities that are not readily
marketable or are subject to restrictions on resale. In certain situations, the Trust could find it more difficult to sell such
securities at desirable times and/or prices. The Trust may not be able to readily dispose of such securities at prices that approximate
those at which the Trust could sell such securities if they were more widely traded or at which the Trust has valued such securities
and, as a result of such illiquidity, the Trust may have to sell other investments or engage in borrowing transactions if necessary
to raise cash to meet its obligations. In addition, the limited liquidity could affect the market price of the securities, thereby
adversely affecting the Trust&#8217;s NAV and ability to make distributions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Municipal
Bond Market Risk.</B></FONT> Investing in the municipal bond market involves certain risks. Certain securities in which the Trust
will invest will not be registered with the SEC or any state securities commission and will not be listed on any national securities
exchange. The amount of public information available about the municipal obligations in the Trust&#8217;s portfolio is generally
less than for corporate equities or bonds, and the investment performance of the Trust may, therefore, be more dependent on the
analytical abilities of Eaton Vance than if the Trust were a stock fund or taxable bond fund.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The ability of municipal issuers to make timely payments of interest
and principal may be diminished during general economic downturns and as governmental cost burdens are reallocated among federal,
state and local governments. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend
the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations, or on the ability
of municipalities to levy taxes. Issuers of municipal obligations might seek protection under the bankruptcy laws. In the event
of bankruptcy of an issuer, the Trust could experience delays in collecting principal and interest to which it is entitled, and
may obtain only a limited recovery or no recovery in such circumstances. To enforce its rights in the event of default in the payment
of interest or repayment of principal, or both, the Trust may take possession of and manage the assets securing the issuer&#8217;s obligations on such securities, which
may increase the Trust&#8217;s operating expenses. Any income derived from the Trust&#8217;s ownership or operation of such assets
may not be tax-exempt.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The value of municipal securities generally may be affected by
uncertainties in the municipal markets as a result of legislation or litigation, including legislation or litigation that changes
the taxation of municipal securities or the rights of municipal security holders in the event of a bankruptcy. Certain provisions
of the U.S. Bankruptcy Code governing such bankruptcies are unclear. Further, the application of state law to municipal security
issuers could produce varying results among the states or among municipal security issuers within a state. These uncertainties
could have a significant impact on the prices of the municipal securities in which the Trust invests.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">If the number of municipal borrowers and the amount of outstanding
municipal securities contract, without corresponding reductions in investor demand for municipal securities, the Trust may have
fewer investment alternatives, may invest in securities that it previously would have declined and may concentrate its investments
in a smaller number of issuers.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Below
Investment Grade Securities Risk</B></FONT>. Up to 30% of the Trust&#8217;s investments in municipal obligations may be, at the
time of investment, rated below investment grade or if unrated deemed by the Adviser to be below investment grade. Such obligations
are commonly called &#8220;junk bonds&#8221; and will have speculative characteristics in varying degrees. While such obligations
may have some quality and protective characteristics, these characteristics can be expected to be offset or outweighed by uncertainties
or major risk exposures to adverse conditions.&nbsp;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Below investment grade municipal obligations involve a greater
degree of credit, interest rate and market risk than investment grade municipal obligations. Below investment grade municipal obligations
are subject to a greater risk of an issuer&#8217;s inability to meet principal and interest payments on the obligations and may
also be subject to greater price volatility due to such factors as interest rate sensitivity, market perception of the creditworthiness
of the issuer and general market liquidity. Below investment grade municipal obligations are considered predominantly speculative
because of the credit risk of their issuers. While offering a greater potential opportunity for capital appreciation and higher
yields, below investment grade municipal obligations typically entail greater potential price volatility and may be less liquid
than investment grade municipal obligations. Issuers of below investment grade municipal obligations are more likely to default
on their payments of interest and principal owed to the Trust, and such defaults will reduce the Trust&#8217;s NAV and income distributions.
The prices of these below investment grade obligations are more sensitive to negative developments than higher rated securities.
Adverse economic conditions generally lead to a higher non-payment rate. In addition, below investment grade municipal obligations
may lose significant value before a default occurs as the market adjusts to expected higher non-payment rates.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Increases in interest rates and changes in the economy may adversely
affect the ability of issuers of lower grade municipal obligations to pay interest and to repay principal, to meet projected financial
goals and to obtain additional financing. Issuers of below investment grade municipal obligations may be more adversely affected
by a prolonged recession or continued deterioration of economic conditions. In the event that an issuer of securities held by the
Trust experiences difficulties in the timely payment of principal or interest and such issuer seeks to restructure the terms of
its borrowings, the Trust may incur additional expenses and may determine to invest additional assets with respect to such issuer
or the project or projects to which the Trust&#8217;s portfolio securities relate. Further, the Trust may incur additional expenses
to the extent that it is required to seek recovery upon a default in the payment of interest or the repayment of principal on its
portfolio holdings, and the Trust may be unable to obtain full recovery thereof. When the Trust invests in lower rated or unrated
municipal obligations, the achievement of the Trust&#8217;s investment objectives is more dependent on the Adviser&#8217;s credit
analysis than would be the case if the Trust were investing in municipal obligations rated investment grade.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">To the extent that there is no established market for some of
the lower grade municipal obligations in which the Trust may invest, trading in such securities may be relatively inactive. The
Adviser is responsible for determining the NAV of the Trust, subject to the supervision of the Trust&#8217;s Board. During periods
of reduced market liquidity and in the absence of readily available market quotations for lower grade municipal obligations held
in the Trust&#8217;s portfolio, the ability of the Adviser to value the Trust&#8217;s securities becomes more difficult and the
Adviser&#8217;s use of judgment may play a greater role in the valuation of the Trust&#8217;s securities due to the reduced availability
of reliable objective data. The effects of adverse publicity and investor perceptions may be more pronounced for securities for
which no established market exists as compared with the effects on securities for which a regular market does exist. Further, the
Trust may have more difficulty selling such securities in a timely manner and at their stated value than would be the case for
securities for which an established market does exist.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Municipal obligations held by the Trust that are initially rated
below investment grade may subsequently be determined by the Adviser to be of investment grade quality for purposes of the Trust&#8217;s
investment policies if the securities subsequently are backed by escrow accounts containing U.S. Government obligations. The Trust
may retain in its portfolio an obligation that declines in quality, including defaulted obligations, if such retention is considered
desirable by the Adviser. In the case of a defaulted obligation, the Trust may incur additional expense seeking recovery of its
investment.</P>

Risk.</B></FONT> Municipal obligations may be insured as to their scheduled payment of principal and interest. Although the insurance
feature may reduce some financial risks, the premiums for insurance and the higher market price sometimes paid for insured obligations
may reduce the current yield on the insured obligation. Insured obligations also may be secured by bank credit agreements or escrow
accounts. Changes in the ratings of an insurer may affect the value of an insured obligation, and in some cases may even cause
the value of a security to be less than a comparable uninsured obligation. The insurance does not guarantee the market value of
the insured obligation or the net asset value of the Trust&#8217;s shares. If a municipal obligation is insured, the Trust will
use the higher of the Municipal Obligation Rating or the insurance issuer&#8217;s rating. The obligation of a municipal bond insurance
company to pay a claim extends over the life of each insured obligation. Although defaults on insured municipal obligations have
been low to date and municipal bond insurers have met their claims, there is no assurance this will continue. A higher than expected
default rate could strain the insurer&#8217;s loss reserves and adversely affect its ability to pay claims to bondholders. Because
a significant portion of insured municipal obligations that have been issued and are outstanding is insured by a small number of
insurance companies, an event involving one or more of these insurance companies, such as a credit rating downgrade, could have
a significant adverse effect on the value of the municipal obligations insured by that insurance company and on the municipal bond
markets as a whole.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Current
Regulatory Environment Risk.</B></FONT> From time to time proposals have been introduced before Congress for the purpose of restricting
or eliminating the federal income tax exemption for interest on certain types of municipal obligations, and it can be expected
that similar proposals may be introduced in the future. Any proposed or actual changes in such rates or exempt status, therefore,
can significantly affect the demand for and supply, liquidity and marketability of municipal obligations. This could in turn affect
the Trust&#8217;s net asset value and ability to acquire and dispose of municipal obligations at desirable yield and price levels.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The U.S. and non-U.S. derivatives markets have undergone substantial
changes in recent years as a result of changes under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the &#8220;Dodd-Frank
Act&#8221;) in the United States and regulation changes in Europe, Asia and other non-U.S. jurisdictions. In particular, the Dodd-Frank
Act and related regulations require many derivatives to be cleared and traded on an exchange, expand entity registration requirements,
impose business conduct requirements on counterparties, and impose other regulatory requirements that will continue to change derivatives
markets as regulations are implemented. Additional future regulation of the derivatives markets may make the use of derivatives
more costly, may limit the availability or reduce the liquidity of derivatives, and may impose limits or restrictions on the counterparties
with which the Trust engages in derivative transactions. Trust management cannot predict the effects of any new governmental regulation
that may be implemented, and future regulation may impair the effectiveness of the Trust&#8217;s derivative transactions and its
ability to achieve its investment objectives.</P>

may be enacted that could negatively affect the assets of the Trust. Legislation or regulation may change the way in which the
Trust itself is regulated. The Adviser cannot predict the effects of any new governmental regulation that may be implemented,

its investment objectives.</P>

may be collateralized by the proceeds from class action or other litigation against the tobacco industry. Such municipal obligations
are backed solely by expected revenues to be derived from lawsuits involving tobacco-related deaths and illnesses which were settled
between certain states and American tobacco companies. Tobacco settlement bonds are secured by an issuing state&#8217;s proportionate
share in the Master Settlement Agreement (&#8220;MSA&#8221;). The MSA is an agreement, reached out of court in November 1998 between
46 states and nearly all of the major U.S. tobacco manufacturers. Under the terms of the MSA, the actual amount of future settlement
payments by tobacco manufacturers is dependent on many factors, including, but not limited to, annual domestic cigarette shipments,
reduced cigarette consumption, increased taxes on cigarettes, inflation, financial capability of tobacco companies, continuing
litigation and the possibility of tobacco manufacturer bankruptcy. Payments made by tobacco manufacturers could be negatively impacted
if the decrease in tobacco consumption is significantly greater than the forecasted decline. See &#8220;State Specific Investments&#8221;

interest bonds pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and provide
the economic effect of leverage. The interest rate payable on a residual interest bond also bears an inverse relationship to the
interest rate on floating rate notes issued by the SPV (&#8220;Floating Rate Notes&#8221;). Because changes in the interest rate
on the Floating Rate Notes inversely affect the interest paid on the residual interest bond, the value and income of a residual

the extreme, eliminate the interest paid to the Trust when short-term interest rates rise, and increase the interest paid to the
Trust when short-term interest rates fall. Residual interest bonds have varying degrees of liquidity, and the market for these
securities is relatively volatile. These securities tend to underperform the market for fixed rate bonds in a rising long-term
interest rate environment, but tend to outperform the market for fixed rate bonds when long-term interest rates decline. Although
volatile, residual interest bonds typically offer the potential for yields exceeding the yields available on fixed rate bonds with
comparable credit quality and maturity. These securities usually permit the investor to convert the floating rate to a fixed rate
(normally adjusted downward), and this optional conversion feature may provide a partial hedge against rising rates if exercised
at an opportune time. While residual interest bonds expose the Trust to leverage risk because they provide two or more dollars
of bond market exposure for every dollar invested, they are not subject to the Trust&#8217;s restrictions on borrowings.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Any economic effect of leverage through the Trust&#8217;s
purchase of residual interest bonds will create an opportunity for increased Common Share net income and returns, but will also
create the possibility that the Trust&#8217;s long-term returns will be diminished if the cost of leverage exceeds the return on
the bonds purchased with leverage by the Trust. The amount of fees paid to Eaton Vance for investment advisory services will be
higher if the Trust uses financial leverage because the fees will be calculated based on the Trust&#8217;s average daily gross
assets, which may create a conflict of interest between Eaton Vance and the Common Shareholders. &#8220;Gross assets&#8221; of
the Trust means the total assets of the Trust, including assets attributable to any form of leverage, minus all accrued expenses
incurred in the normal course of operations, but not excluding any liabilities or obligations attributable to leverage. See &#8220;Investment

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">A SPV typically can be collapsed or closed by the holder of
the residual interest bonds (such as the Trust) or by the liquidity provider. In certain circumstances, the Trust may enter into
shortfall and forbearance agreements with respect to a residual interest bond. The Trust generally may enter into such agreements
(i) when the liquidity provider to the SPV requires such an agreement because the level of leverage in the SPV exceeds the level
that the liquidity provider is willing support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider
from collapsing the SPV in the event that the municipal obligation held in the SPV has declined in value. Such agreements commit
the Trust to reimburse, upon the termination of the SPV issuing the inverse floater, the difference between the liquidation value
of the underlying security (which is the basis of the inverse floater) and the principal amount due to the holders of the floating
rate security issued in conjunction with the inverse floater. Such agreements may expose a Trust&#8217;s other assets to losses.
Absent a shortfall and forbearance agreement, the Trust would not be required to make such a reimbursement. If the Trust chooses
not to enter into such an agreement, the inverse floater could be terminated and the Trust could incur a loss. Consistent with
SEC staff guidance, the Trust will segregate or earmark liquid assets with its custodian on a mark-to-market basis to cover any
such payment obligations to liquidity providers.</P>

rules implementing section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the &#8220;Volcker Rule&#8221;).
The Volcker Rule prohibits banking entities from engaging in proprietary trading of certain instruments and limits such entities&#8217;
investments in, and relationships with, covered funds, as defined in the rules. The Volcker Rule precludes banking entities and
their affiliates from (i) sponsoring residual interest bond programs as presently structured and (ii) continuing relationships

Trust to maintain current or desired levels of income.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Risks
of MLOs and Certificates of Participation</B></FONT>. The Trust may invest in MLOs and certificates of participation that involve
special risks not normally associated with general obligations or revenue obligations. A MLO is a bond that is secured by lease
payments made by the party, typically a state or municipality, leasing the facilities (e.g., schools or office buildings) that
were financed by the bond. Such lease payments may be subject to annual appropriation or may be made only from revenues associated
with the facility financed. In other cases, the leasing state or municipality is obligated to appropriate funds from its general
tax revenues to make lease payments as long as it utilizes the leased property. A certificate of participation (also referred to
as a &#8220;participation&#8221;) in a municipal lease is an instrument evidencing a pro rata share in a specific pledged revenue
stream, usually lease payments by the issuer . The issuer&#8217;s obligations under such instruments are often subject to the ongoing
appropriation by a legislative body, on an annual or other basis, of funds for the payment thereof. Investments in MLOs and certificates
of participation are therefore typically subject to the risk that the legislative body will not make the necessary annual appropriation
and the issuer will not otherwise be willing or able to meet its obligation.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><B>Inflation Risk/Deflation Risk. </B>Inflation risk is the risk
that the value of assets or income from investment will be worth less in the future as inflation decreases the value of money.
As inflation increases, the real value of the Common Shares and distributions thereon can decline. In addition, during periods
of rising inflation, short-term interest rates and the Trust&#8217;s cost of leverage would likely increase, reducing returns to
Common Shareholders to the extent that such increased cost is not offset by commensurately higher income. Deflation risk is the
risk that prices throughout the economy decline over time &#8722; the opposite of inflation. Deflation may have an
adverse affect on the creditworthiness of issuers and may make issuer defaults more likely, which may result in a decline in the
value of the Trust&#8217;s investments.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Leverage
Risk.</B></FONT> The Trust will not utilize leverage in excess of 15% of its gross assets. As discussed above, the Trust currently
uses leverage created by investing in residual interest bonds. The Trust will comply with the asset segregation requirements of
the 1940 Act in making such investments. Residual interest bonds are securities that pay interest at rates that vary inversely
with changes in prevailing short-term interest rates and provide the economic effect of leverage. Although the Trust has no current
intention to do so, the Trust is authorized to utilize leverage through the issuance of preferred shares and/or borrowings, including
the issuance of debt securities. The Trust may borrow for temporary, emergency or other purposes as permitted by the 1940 Act.
There can be no assurance a leveraging strategy will be successful during any period in which it is employed.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Adviser anticipates that the use of leverage (from residual
interest bonds) may result in higher income to Common Shareholders over time. Leverage creates risks for Common Shareholders, including
the likelihood of greater volatility of NAV and market price of the Common Shares and the risk that fluctuations in the costs of
leverage may affect the return to Common Shareholders. To the extent the income derived from investments purchased with funds received
from leverage exceeds the cost of leverage, the Trust&#8217;s distributions will be greater than if leverage had not been used.
Conversely, if the income from the investments purchased with such funds is not sufficient to cover the cost of leverage, the amount
available for distribution to Common Shareholders will be less than if leverage had not been used. In the latter case, Eaton Vance,
in its best judgment, may nevertheless determine to maintain the Trust&#8217;s leveraged position if it deems such action to be
appropriate. There can be no assurance that a leveraging strategy will be successful.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">As discussed under &#8220;Management of the Trust,&#8221; the
investment advisory fee paid to Eaton Vance is calculated on the basis of the Trust&#8217;s average daily gross assets. &#8220;Gross
assets&#8221; of the Trust shall mean total assets of the Trust, including assets attributable to any form of leverage, minus all
accrued expenses incurred in the normal course of operations, but not excluding any liabilities or obligations attributable to
leverage obtained through (i) indebtedness of any type (including, without limitation, borrowing through a credit facility or the
issuance of debt securities), (ii) the issuance of preferred stock or other similar preference securities, (iii) the reinvestment
of collateral received for securities loaned in accordance with the Trust&#8217;s investment objectives and policies, and/or (iv)
any other means; all as determined in accordance with generally accepted accounting principles. This means that the Trust&#8217;s
advisory fees will be higher when leverage is utilized which may create an incentive for the Adviser to employ leverage. In this
regard, holders of any preferred shares do not bear the investment advisory fee. Rather, Common Shareholders bear the portion of
the investment advisory fee attributable to the assets purchased with the proceeds of the use of leverage, which means that Common
Shareholders effectively bear the entire advisory fee.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Financial leverage may also be achieved through the purchase
of certain derivative instruments. The Trust&#8217;s use of derivative instruments exposes the Trust to special risks. See &#8220;Investment
Objectives, Policies and Risks &#8211; Additional Investment Practices&#8221; and &#8220;Investment Objectives, Policies and Risks
&#8211; Additional Risk Considerations.&#8221;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Derivatives
Risk.</B></FONT> In addition to investing in residual interest bonds, the Trust may invest without limitation in other derivative
instruments (which are instruments that derive their value from a reference instrument) acquired for hedging purposes or investment
purposes, such as financial futures contracts and related options, interest rate, total return and other swaps and forward rate
contracts. Depending on the type of derivative instrument and the Trust&#8217;s investment strategy, a reference instrument could
be a security, instrument, index, currency, commodity, economic indicator or event (&#8220;reference instruments&#8221;). The loss
on derivative instruments (other than purchased options) may substantially exceed amounts invested in these instruments. Derivative
transactions, including options on securities and securities indices and other transactions in which the Trust may invest may subject
the Trust to increased risk of principal loss due to unexpected movements in securities prices and interest rates, and imperfect
correlations between the Trust&#8217;s securities holdings and indices upon which derivative transactions are based. Derivatives
can be illiquid, may disproportionately increase losses, and may have a potentially large impact on the Trust&#8217;s performance.
Use of derivative instruments may cause the realization of higher amounts of short-term capital gains (generally taxed at ordinary
income tax rates) than if such instruments had not been used. Trust obligations created pursuant to derivative instruments may
give rise to leverage, which would subject the Trust to increased leverage risk. The Trust also will be subject to credit risk
with respect to the counterparties to any OTC derivatives contracts entered into by the Trust. If a counterparty becomes bankrupt
or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Trust may experience
significant delays in obtaining any recovery under the derivative contract in a bankruptcy or other reorganization proceeding.
The Trust may obtain only a limited recovery or no recovery in such circumstances.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The use of derivatives to enhance income is considered to
be speculative in nature. The use of derivatives may result in greater losses than if they had not been used, may require the Trust
to sell or purchase portfolio investments at inopportune times or for prices other than current market value, may limit the amount
of appreciation the Trust can realize on an investment or may cause the Trust to hold a security it might otherwise sell. Segregated
liquid assets, amounts paid by the Trust as premiums and cash or other assets held in margin accounts with respect to derivatives
transactions are not otherwise available to the Trust for investment or operational
purposes. Certain derivative transactions may have economic characteristics similar to leverage. See &#8220;Additional Risk Considerations
- Leverage Risk.&#8221;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The U.S. and non-U.S. derivatives markets have undergone substantial
changes in recent years as a result of changes under the Dodd-Frank Act in the United States and regulation changes in Europe,
Asia and other non-U.S. jurisdictions. In particular, the Dodd-Frank Act and related regulations require many derivatives to be
cleared and traded on an exchange, expand entity registration requirements, impose business conduct requirements on counterparties,
and impose other regulatory requirements that will continue to change derivatives markets as regulations are implemented. Additional
future regulation of the derivatives markets may make the use of derivatives more costly, may limit the availability or reduce
the liquidity of derivatives, and may impose limits or restrictions on the counterparties with which the Trust engages in derivative
transactions. Trust management cannot predict the effects of any new governmental regulation that may be implemented, and future
regulation may impair the effectiveness of the Trust&#8217;s derivative transactions and its ability to achieve its investment
objectives.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Counterparty
Risk.</B></FONT> Changes in the credit quality of the companies that serve as the Trust&#8217;s counterparties with respect to
its derivatives positions and liquidity providers for the Trust&#8217;s residual interest bonds or other investments supported
by another party&#8217;s credit will affect the value of those instruments. Certain entities that have served as counterparties
in the municipals markets have in the past incurred significant financial hardships, including bankruptcy and material loss of
credit standing as a result of exposure to investments that have experienced defaults or otherwise suffered extreme credit deterioration.
As a result, such hardships reduced these entities&#8217; capital and called into question their continued ability to perform their
obligations. By using derivatives or other instruments that expose the Trust to counterparties, the Trust assumes the risk that
its counterparties could experience future financial hardship.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 0">The counterparty risk for cleared derivatives is generally lower
than for uncleared over-the-counter derivative transactions since generally a clearing organization becomes substituted for each
counterparty to a cleared derivative contract and, in effect, guarantees the parties' performance under the contract as each party
to a trade looks only to the clearing organization for performance of financial obligations under the derivative contract. However,
there can be no assurance that a clearing organization, or its members, will satisfy its obligations to the Trust.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Tax
Risk.</B></FONT> The value of the Trust&#8217;s investments and its NAV may be adversely affected by changes in tax rates and policies.
Because interest income from municipal obligations normally is not subject to regular federal income taxation, the attractiveness
of municipal obligations in relation to other investment alternatives is affected by changes in federal income tax rates or changes
in the tax-exempt status of interest income from municipal obligations. From time to time proposals have been introduced before
Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on certain types of municipal
obligations, and it can be expected that similar proposals may be introduced in the future. Any proposed or actual changes in such
rates or exempt status, therefore, can significantly affect the demand for and supply, liquidity and marketability of municipal
obligations. This could, in turn, affect the Trust&#8217;s NAV and ability to acquire and dispose of municipal obligations at desirable
yield and price levels. The Trust is not a suitable investment for individual retirement accounts, for other tax-exempt or tax-deferred
accounts or for investors who are otherwise indifferent to the federal income tax consequences of their investments. See &#8220;Distributions&#8221;
and &#8220;Federal income tax matters.&#8221;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust will invest in municipal obligations in reliance at
the time of purchase on an opinion of bond counsel to the issuer that the interest paid on those securities will be excludable
from gross income under the regular federal income tax, and the Adviser will typically not independently verify that opinion. Subsequent
to the Trust&#8217;s acquisition of such a municipal security, however, the security may be determined to pay, or to have paid,
taxable income. As a result, the treatment of dividends previously paid or to be paid by the Trust as &#8220;exempt-interest dividends&#8221;
could be adversely affected, subjecting the Trust&#8217;s Common Shareholders to increased federal income tax liabilities.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Interest income from certain types of municipal obligations
may be a tax preference item for purposes of the AMT for individual investors.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Futures
Risk.</B></FONT> Although some futures contracts call for making or taking delivery of the underlying reference instrument, generally
these obligations are closed out prior to delivery by offsetting purchases or sales of matching futures contracts (same exchange,
underlying security or index, and delivery month). Closing a futures contract sale is effected by purchasing a futures contract
for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If an offsetting
purchase price is less than the original sale price, the Trust realizes a capital gain, or if it is more, the Trust realizes a
capital loss. Conversely, if an offsetting sale price is more than the original purchase price, the Trust realizes a capital gain,
or if it is less, the Trust realizes a capital loss. The Adviser has claimed an exclusion from the definition of a Commodity Pool
Operator (&#8220;CPO&#8221;) under the Commodity Exchange Act with respect to the Trust and therefore, neither the Adviser nor
the Trust are subject to registration or regulation thereunder.</P>

the success of the Trust depends upon the investment skills and analytical abilities of Eaton Vance and the individual portfolio

Market Conditions.</B></FONT> An outbreak of respiratory disease caused by a novel coronavirus was first detected in China in December
2019 and subsequently spread internationally. This coronavirus has resulted in closing borders, enhanced health screenings, healthcare
service preparation and delivery, quarantines, cancellations, disruptions to supply chains and customer activity, as well as general
concern and uncertainty. The impact of this coronavirus may last for an extended period of time and result in a substantial economic
downturn.&nbsp; Health crises caused by outbreaks, such as the coronavirus outbreak, may exacerbate other pre-existing political,
social and economic risks and disrupt normal market conditions and operations. The impact of this outbreak, and other epidemics
and pandemics that may arise in the future, could negatively affect the worldwide economy, as well as the economies of individual
countries, individual companies and the market in general in significant and unforeseen ways.&nbsp; Any such impact could adversely
affect the Trust&#8217;s performance, or the performance of the securities in which the Trust invests and may lead to losses on
your investment in the Trust.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Cybersecurity
Risk.</B></FONT> With the increased use of technologies by Trust service providers to conduct business, such as the Internet, the
Trust is susceptible to operational, information security and related risks. The Trust relies on communications technology, systems,
and networks to engage with clients, employees, accounts, shareholders, and service providers, and a cyber incident may inhibit
the Trust&#8217;s ability to use these technologies. In general, cyber incidents can result from deliberate attacks or unintentional
events. Cyber attacks include, but are not limited to, gaining unauthorized access to digital systems (e.g., through &#8220;hacking&#8221;
or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational
disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing
denial-of-service attacks on websites. A denial-of-service attack is an effort to make network services unavailable to intended
users, which could cause shareholders to lose access to their electronic accounts, potentially indefinitely. Employees and service
providers also may not be able to access electronic systems to perform critical duties for the Trust, such as trading and NAV calculation,
during a denial-of-service attack. There is also the possibility for systems failures due to malfunctions, user error and misconduct
by employees and agents, natural disasters, or other foreseeable and unforeseeable events.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Because technology is consistently changing, new ways to carry
out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for,
or that an attack may not be detected, which puts limitations on the Trust&#8217;s ability to plan for or respond to a cyber attack.
Like other Trusts and business enterprises, the Trust and its service providers have experienced, and will continue to experience,
cyber incidents consistently. In addition to deliberate cyber attacks, unintentional cyber incidents can occur, such as the inadvertent
release of confidential information by the Trust or its service providers. To date, cyber incidents have not had a material adverse
effect on the Trust&#8217;s business operations or performance.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust uses third party service providers who are also
heavily dependent on computers and technology for their operations. Cybersecurity failures or breaches by the Trust&#8217;s investment
adviser or administrator and other service providers (including, but not limited to, the custodian or transfer agent), and the
issuers of securities in which the Trust invests, may disrupt and otherwise adversely affect their business operations. This may
result in financial losses to the Trust, impede Trust trading, interfere with the Trust&#8217;s ability to calculate its NAV, or
cause violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other
compensation costs, litigation costs, or additional compliance costs. While many of the Trust service providers have established
business continuity plans and risk management systems intended to identify and mitigate cyber attacks, there are inherent limitations
in such plans and systems including the possibility that certain risks have not been identified. The Trust cannot control the cybersecurity
plans and systems put in place by service providers to the Trust and issuers in which the Trust invests. The Trust and its shareholders
could be negatively impacted as a result.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Other
Investment Companies Risk.</B></FONT> The Trust may, subject to the limitations of the 1940 Act, invest in the securities of other
investment companies. Such securities may be leveraged. As a result, the Trust may be indirectly exposed to leverage through an
investment in such securities. Utilization of leverage is a speculative investment technique and involves certain risks. The Trust,
as a holder of the securities of other investment companies, will bear its pro rata portion of the other investment companies&#8217;
expenses, including advisory fees. These expenses are in addition to the direct expenses of the Trust&#8217;s own operations.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Swaps
Risk.</B></FONT> Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging
from a few weeks to more than one year. In a standard &#8220;swap&#8221; transaction, two parties agree to exchange the returns
(or differentials in rates of return) earned or realized on a particular predetermined reference instrument or instruments, which
can be adjusted for an interest rate factor. The gross returns to be exchanged or &#8220;swapped&#8221; between the parties are
generally calculated with respect to a &#8220;notional amount&#8221; (i.e., the return on or increase in value of a particular
dollar amount invested at a particular interest rate or in a &#8220;basket&#8221; of securities representing a particular index).
Other types of swap agreements may calculate the obligations of the parties to the agreement on a &#8220;net basis.&#8221; Consequently,
a party&#8217;s current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid
or received under the agreement based on the relative values of the positions held by each party to the agreement (the &#8220;net
amount&#8221;). <FONT STYLE="font-family: Arial, Helvetica, Sans-Serif; font-weight: normal">Whether the use of swap agreements
will be successful will depend on the Adviser&#8217;s ability to predict correctly whether certain types of reference instruments
are likely to produce greater returns than other instruments. Swap agreements may be subject to contractual restrictions on transferability
and termination and they may have terms of greater than seven days. The Trust&#8217;s obligations under a swap agreement will be
accrued daily (offset against any amounts owed to the Trust under the swap). Developments in the swaps market, including potential
government regulation, could adversely affect the Trust&#8217;s ability to terminate existing swap agreements or to realize amounts
to be received under such agreements, as well as to participate in swap agreements in the future. If there is a default by the
counterparty to a swap, the Trust will have contractual remedies pursuant to the swap agreement, but any recovery may be delayed
depending on the circumstances of the default.</FONT></P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Duration
and Maturity Risk.</B></FONT> Holding long duration and long maturity investments will expose the Trust to certain magnified risks.
These risks include interest rate risk, credit risk and liquidity risks as discussed above.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Hedging
Risk.</B></FONT> The Trust&#8217;s use of derivatives or other transactions to reduce risks involves costs and will be subject
to Eaton Vance&#8217;s ability to predict correctly changes in the relationships of such hedge instruments to the Trust&#8217;s
portfolio holdings or other factors. No assurance can be given that Eaton Vance&#8217;s judgment in this respect will be correct.
In addition, no assurance can be given that the Trust will enter into hedging or other transactions at times or under circumstances
in which it may be advisable to do so. Hedging transactions have risks, including the imperfect correlation between the value of
such instruments and the underlying assets of the Trust, which creates the possibility that the loss on such instruments may be
greater than the gain, if any, in the value of the underlying asset in the Trust&#8217;s portfolio; the limited availability of
such instruments; the loss of principal; the possible default of the other party to the transaction; illiquidity of the derivative
investments; and the imperfect correlation between the tax-exempt and taxable markets. Furthermore, the ability to successfully
use hedging transactions depends on the Eaton Vance&#8217;s ability to predict pertinent market movements, which cannot be assured.
Thus, the use of hedging transactions may result in losses greater than if they had not been used, may require the Trust to sell
or purchase portfolio investments at inopportune times or for prices other than current market values, may limit the amount of
appreciation the Trust can realize on an investment, or may cause the Trust to hold a security that it might otherwise sell.</P>

of a 5% annual return are required by regulations of the SEC that are applicable to all investment companies; the assumed 5% annual

For more complete descriptions of certain of the Trust&#8217;s costs and expenses, see &#8220;Management of the Trust.&#8221; In
addition, while the example assumes reinvestment of all dividends and distributions at NAV, participants in the Trust&#8217;s dividend
reinvestment plan may receive Common Shares purchased or issued at a price or value different from NAV. See &#8220;Distributions&#8221;

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">TRADING AND NAV INFORMATION</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust&#8217;s Common Shares have traded both at a premium
and a discount to NAV. The Trust cannot predict whether its shares will trade in the future at a premium or discount to NAV. The
provisions of the 1940 Act generally require that the public offering price of Common Shares (less any underwriting commissions
and discounts) must equal or exceed the NAV per share of a company&#8217;s common stock (calculated within 48 hours of pricing).
The issuance of Common Shares may have an adverse effect on prices in the secondary market for the Trust&#8217;s common shares
by increasing the number of Common Shares available, which may put downward pressure on the market price for the Trust&#8217;s
Common Shares. Shares of common stock of closed-end investment companies frequently trade at a discount from NAV. See &#8220;Additional
Risk Considerations &#8211; Discount from or Premium to NAV&#8221;.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In addition, the Trust&#8217;s Board of Trustees has authorized
the Trust to repurchase up to 10% of its outstanding Common Shares as of the day of the prior calendar year-end at market prices
when shares are trading at a discount to net asset value. The share repurchase program does not obligate the Trust to purchase
a specific amount of shares. The results of the share repurchase program are disclosed in the Trust&#8217;s annual and semi-annual
reports to shareholders.&nbsp; See &#8220;Description of Capital Structure &#8211; Repurchase of Common Shares and Other Discount
Measures.&#8221;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The following table sets forth for each of the periods indicated
the high and low closing market prices for Common Shares on the NYSE, and the corresponding NAV per share and the premium or discount
to NAV per share at which the Trust&#8217;s Common Shares were trading as of such date.</P>

current income exempt from federal income tax. The Trust will, as a secondary investment objective, seek to achieve capital appreciation.
The Trust will seek to achieve its investment objectives by investing primarily in municipal obligations (as defined below) that,
at the time of investment, are investment grade quality. The Trust also may invest a portion of its gross assets in municipal obligations
rated below investment grade or unrated securities that the Adviser considers to be of comparable quality.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">PRIMARY INVESTMENT POLICIES</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>General
Composition of the Trust.</B></FONT> During normal market conditions, the Trust will invest at least 80% of its gross assets in
debt obligations issued by or on behalf of states, territories and possessions of the United States, including the District of
Columbia, and their political subdivisions, agencies or instrumentalities, the interest on which is exempt from regular federal
income tax (&#8220;municipal obligations&#8221;). For purposes of this 80% policy, municipal obligations will include investments
in residual interest bonds whose interest is exempt from regular federal income tax. During normal market conditions, at least
70% of the Trust&#8217;s investments in municipal obligations will be investment grade quality at time of investment. A municipal
obligation is considered investment grade quality if it is either (i) rated within the four highest ratings categories by at least
one nationally recognized statistical rating organization (a &#8220;Rating Agency&#8221;), which are those rated Baa or higher
by Moody&#8217;s Investors Service, Inc. (&#8220;Moody&#8217;s&#8221;) or BBB or higher by Standard &amp; Poor&#8217;s Ratings</P>

or (ii) an unrated municipal obligation that the Trust&#8217;s investment adviser considers to be of investment grade quality.
If a municipal obligation is rated differently by two or more Rating Agencies, the Trust will use the higher of such ratings (the
&#8220;Municipal Obligation Rating&#8221;). If a municipal obligation is insured, the Trust will use the higher of the Municipal
Obligation Rating or the insurance issuer&#8217;s rating. Securities rated in the fourth highest category (i.e., Baa by Moody&#8217;s
or BBB by S&amp;P or Fitch) are considered investment grade quality, but may have speculative characteristics.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Up to 30% of the Trust&#8217;s investments in municipal obligations
may be in securities of issuers that are below investment grade quality at time of investment. A municipal obligation is considered
below investment grade quality if it is either (i) rated below investment grade by a Rating Agency, or (ii) an unrated municipal
obligation that the Trust&#8217;s investment adviser considers to be of comparable quality. Municipal obligations of below investment
grade quality (commonly referred to as &#8220;junk&#8221; bonds) involve special risks as compared to municipal obligations of
investment grade quality. These risks include greater sensitivity to a general economic downturn, greater market price volatility
and less secondary market trading. The Trust may invest in below investment grade municipal obligations of any quality. This means
that the Trust&#8217;s investments in municipal obligations may include securities of issuers that are having financial difficulties,
which may include being in default on obligations to pay principal or interest thereon when due or involved in bankruptcy or insolvency

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Municipal
Obligations.</B></FONT> Municipal obligations include bonds (including general obligation and revenue bonds), notes and commercial
paper issued by a municipality, a group of municipalities or participants in qualified issues of municipal debt for a wide variety
of both public and private purposes. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Issuers of general obligation bonds include states, counties,
cities, towns and regional districts. The proceeds of these obligations are used to fund a wide range of public projects, including
the construction or improvement of schools, highways and roads, water and sewer systems and a variety of other public purposes.
The basic security of general obligation bonds is the issuer&#8217;s pledge of its faith, credit, and taxing power for the payment
of principal and interest. The taxes that can be levied for the payment of debt service may be limited or unlimited as to rate
and amount. General obligation bonds issued by municipalities can be adversely affected by economic downturns and the resulting
decline in tax revenues, pension funding risk, other post-employment benefit risk, budget imbalances, taxing ability risk, lack
of political willpower and federal funding risk, among others. Revenue bonds are payable only from the revenues derived from a
particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue
source such as payments from the user of the facility being financed. Revenue bonds can be adversely affected by the negative economic
viability of the facility or revenue source. Industrial development bonds are normally secured by the revenues from the project
and not by state or local government tax payments. They are subject to a wide variety of risks, many of which relate to the nature
of the specific project. Generally industrial development bonds are sensitive to the risk of a slowdown in the economy. Municipal
obligations also include municipal lease obligations and certificates of participations in municipal leases.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Certain municipal obligations may be purchased on a &#8220;when-issued&#8221;
basis, which means that payment and delivery occur on a future settlement date. The price and yield of such securities are generally
fixed on the date of commitment to purchase.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may invest in zero coupon bonds, which do not make
cash interest payments during a portion or all of the life of the bond. Instead, such bonds are sold at a deep discount to face
value, and the interest consists of the gradual appreciation in price as the bond approaches maturity. Zero coupon bonds can be
an attractive financing method for issuers with near-term cash-flow problems or seeking to preserve liquidity. Principal only investments
entitle the Trust to receive the stated value of such investment when held to maturity. The values of zero coupon bonds and principal
only investments are subject to greater fluctuation in response to changes in market interest rates than municipal obligations
that pay interest currently. The Trust is required to distribute to shareholders income imputed to any zero coupon bonds or principal
only investments even though such income may not be received by the Trust as distributable cash. Such distributions could reduce
the Trust&#8217;s reserve position and require it to sell securities and incur a gain or loss at a time it may not otherwise want
to in order to provide the cash necessary for these distributions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The interest on tax-exempt municipal obligations is (in the
opinion of the issuer&#8217;s counsel) exempt from regular federal income and state or local taxes, as applicable. Income from
certain types of municipal obligations generally may be subject to the federal alternative minimum tax (the &#8220;AMT&#8221;)
for individuals. Investors subject to AMT should consult their tax advisors.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Many municipal obligations provide the issuer the option to
&#8220;call,&#8221; or redeem, its securities. As such, the effective maturity of a municipal obligation may be reduced as the
result of such call provisions and, if an investment is called in a declining interest rate environment, the proceeds from the
called bond may have to be reinvested at a lower interest rate.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Up to 5% of the Trust&#8217;s investments in municipal obligations
may be collateralized by the proceeds from class action or other litigation against the tobacco industry. Such municipal obligations
are backed solely by expected revenues to be derived from lawsuits involving tobacco-related deaths and illnesses which were settled
between certain states and American tobacco companies. Tobacco settlement bonds are secured by an issuing state&#8217;s proportionate
share in the Master Settlement Agreement (&#8220;MSA&#8221;). The MSA is an agreement, reached out of court in November 1998 between
46 states and nearly all of the U.S. tobacco manufacturers. Under the terms of the MSA, the actual amount of future settlement
payments by tobacco manufacturers is dependent on many factors, including, but not limited to, annual domestic cigarette shipments,
reduced cigarette consumption, increased taxes on cigarettes, inflation, financial capability of tobacco companies, continuing
litigation and the possibility of tobacco manufacturer bankruptcy. Payments made by tobacco manufacturers could be negatively impacted
if the decrease in tobacco consumption is significantly greater than the forecasted decline. See &#8220;State Specific Investments&#8221;
in the SAI for additional information about tobacco settlement bonds and the MSA.</P>

Lease Obligations (&#8220;MLOs&#8221;) and Certificates of Participation.</B></FONT> MLOs are bonds that are secured by lease payments
made by the party, typically a state or municipality, leasing the facilities (e.g., schools or office buildings) that were financed
by the bond. Interest income from MLOs is generally exempt from local and state taxes in the state of issuance. MLOs, like other
municipal debt obligations, are subject to the risk of non-payment. Although MLOs do not constitute general obligations of the
issuer for which the issuer&#8217;s unlimited taxing power is pledged, the leasing state of municipality may be obligated to appropriate
funds from its general tax revenues to make lease payments as long as it</P>

to annual appropriation or may be made only from revenues associated with the facility financed. For example, certain lease obligations
contain &#8220;non-appropriation&#8221; clauses, which provide that the issuer has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a yearly basis. Although &#8220;non-appropriation&#8221;
lease obligations may be secured by the leased property, disposition of the property in the event of foreclosure might prove difficult.
A certificate of participation (also referred to as a &#8220;participation&#8221;) in a municipal lease is an instrument evidencing
a pro rata share in a specific pledged revenue stream, usually lease payments by the issuer that are typically subject to annual
appropriation. The certificate generally entitles the holder to receive a share, or participation, in the payments from a particular
project.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">MLOs and participations therein represent a type of financing
that may not have the depth of marketability associated with more conventional securities and, as such, they may be less liquid
than conventional securities.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The ability of issuers of MLOs to make timely lease payments
may be adversely impacted in general economic downturns and as relative governmental cost burdens are allocated and reallocated
among federal, state and local governmental units. Such non-payment would result in a reduction of income from and value of the
obligation. Issuers of MLOs might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, holders
of MLOs could experience delays and limitations with respect to the collection of principal and interest on such MLOs and may not,
in all circumstances, be able to collect all principal and interest to which it is entitled. To enforce its rights in the event
of a default in lease payments, the Trust might take possession of and manage the assets securing the issuer&#8217;s obligations
on such securities or otherwise incur costs to protect its right, which may increase the Trust&#8217;s operating expenses and adversely
affect the net asset value of the Trust. When the lease contains a non-appropriation clause, however, the failure to pay would
not be a default and the Trust would not have the right to take possession of the assets. Any income derived from the Trust&#8217;s
ownership or operation of such assets may not be tax-exempt.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Municipal
Notes</B></FONT>. Municipal securities in the form of notes, generally are used by municipal issuers to provide for short-term
capital needs, in anticipation of an issuer&#8217;s receipt of other revenues or financing, and typically have maturities of up
to three years. Municipal notes include bond anticipation, tax anticipation and revenue anticipation notes. Bond, tax and revenue
anticipation notes are short-term obligations that are intended to be retired with the proceeds of an anticipated bond issue, tax
revenue or facility revenue, respectively. Generally, tax anticipation notes are issued in anticipation of various tax revenues,
such as income, sales, property, use and business taxes, and are payable from these specific future taxes. Revenue anticipation
notes are issued in expectation of receipt of other kinds of revenue, such as federal revenues available under federal revenue
sharing programs. Bond anticipation notes are issued to provide interim financing until long-term bond financing can be arranged.
In most cases, the long-term bonds then provide the funds needed for repayment of the bond anticipation notes. Tax and revenue
anticipation notes combine individual characteristics of tax anticipation notes and revenue anticipation notes. The anticipated
revenues from taxes, grants or bond financing generally secure the obligations of an issuer of municipal notes. An investment in
such instruments, however, presents a risk that the anticipated revenues will not be received or that such revenues will be insufficient
to satisfy the issuer&#8217;s payment obligations under the notes or that refinancing will be otherwise unavailable.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Residual
Interest Bonds</B></FONT><B><FONT STYLE="font-family: NewsGoth Lt BT,sans-serif">.</FONT></B> Residual interest bonds are securities
that pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and provide the
economic effect of leverage. In general, income on residual interest bonds will decrease when short-term interest rates increase
and increase when short-term interest rates decrease. Residual interest bonds have varying degrees of liquidity, and the market
for these securities is relatively volatile. Residual interest bonds create investment leverage in the Trust because they provide
more than one dollar of exposure to municipal bonds for each dollar the Trust invests in them.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may invest in residual interest bonds, also referred
to as inverse floating rate securities, whereby the Trust may sell a variable or fixed rate bond for cash to a SPV, (which is generally
organized as a trust), while at the same time, buying a residual interest in the assets and cash flows of the SPV. The bond is
deposited into the SPV with the same CUSIP number as the bond sold to the SPV by the Trust, and which may have been, but is not
required to be, the bond purchased from the Trust (the &#8220;Bond&#8221;). The SPV also issues Floating Rate Notes which are sold
to third-parties. The residual interest bond held by the Trust gives the Trust the right (1) to cause the holders of the Floating
Rate Notes to generally tender their notes at par, and (2) to have the Bond held by the SPV transferred to the Trust, thereby terminating
the SPV. Should the Trust exercise such right, it would generally pay the SPV the par amount due on the Floating Rate Notes and
exchange the residual interest bond for the underlying Bond. Pursuant to generally accepted accounting principles, the Trust accounts
for the transaction described above as a secured borrowing by including the Bond in its portfolio of investments and the Floating
Rate Notes as a liability. The Floating Rate Notes have interest rates that generally reset weekly and their holders have the option
to tender their notes to the SPV for redemption at par at each reset date. The SPV may be terminated by the Trust, as noted above,
or by the occurrence of certain termination events as defined in the trust agreement, such as a downgrade in the credit quality
of the underlying Bond, bankruptcy of or payment failure by the issuer of the underlying Bond, the inability to remarket Floating
Rate Notes that have been tendered due to insufficient buyers in the market, or the failure
by the SPV to obtain renewal of the liquidity agreement under which liquidity support is provided for the Floating Rate Notes up
to one year.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In certain circumstances, the Trust may enter into shortfall
and forbearance agreements relating to a residual interest bond held by the Trust. Such agreements commit the Trust to reimburse
the difference between the liquidation value of the underlying security (which is the basis of the residual interest bond) and
the principal amount due to the holders of the floating rate security issued in conjunction with the residual interest bond upon
the termination of the trust issuing the residual interest bond. Absent a shortfall and forbearance agreement, the Trust would
not be required to make such a reimbursement. If the Trust chooses not to enter into such an agreement, the residual interest bond
could be terminated and the Trust could incur a loss. The Trust had no shortfalls as of March 31, 2020.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may also purchase residual interest bonds in a secondary
market transaction without first owning the underlying bond. Such transactions are not required to be treated as secured borrowings.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust&#8217;s investment policies and restrictions expressly
permit investments in residual interest bonds. Such bonds typically offer the potential for yields exceeding the yields available
on fixed rate bonds with comparable credit quality and maturity. These securities tend to underperform the market for fixed rate
bonds in a rising long-term interest rate environment, but tend to outperform the market for fixed rate bonds when long-term interest
rates decline. The value and income of residual interest bonds are generally more volatile than that of a fixed rate bond. The
Trust&#8217;s investment policies do not allow the Trust to borrow money except as permitted by the 1940 Act. The Adviser believes
that the Trust&#8217;s restrictions on borrowing money and issuing senior securities (other than as specifically permitted) do
not apply to Floating Rate Notes issued by the SPV and included as a liability in the Trust&#8217;s statement of assets and liabilities.
As secured indebtedness issued by an SPV, Floating Rate Notes are distinct from the borrowings and senior securities to which the
Trust&#8217;s restrictions apply. Residual interest bonds held by the Trust are securities exempt from registration under Rule
144A of the Securities Act of 1933, as amended (the &#8220;Securities Act&#8221;).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">As of March 31, 2020, the actual leverage attributable to
the floating-rate notes was 6.89% of the Trust&#8217;s net assets.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Short-Term
Floating Rate Securities.</B></FONT> The Trust may also invest in Floating-Rate Notes, as described above, issued by SPVs. The
short-term floating rate security will be linked to a reference interest rate (such as LIBOR or the SIFMA Municipal Bond Swap Index)
and the SPV&#8217;s income will be used to pay the coupon on the Floating-Rate Notes. Generally, the interest rate earned on Floating-Rate
Notes will be based upon the market rates for municipal obligations with maturities or remarketing provisions that are comparable
in duration to the periodic interval of the tender option, which may vary from weekly, to monthly, to extended periods of one year
or multiple years. Since the option feature has a shorter term than the final maturity or first call date of the underlying bond
deposited in the trust, the Trust as the holder of the Floating-Rate Notes relies upon the terms of the agreement with the financial
institution furnishing the option as well as the credit strength of that institution. As further assurance of liquidity, the terms
of the SPV provide for a liquidation of the Bond and the application of the proceeds to pay off the Floating-Rate Notes. The SPVs
that are organized to issue both Floating-Rate Notes and residual interest bonds generally include liquidation triggers to protect
the investor in the Floating-Rate Notes. Generally, the SPVs do not have recourse to the investors in the residual interest bonds.
However, the Trust may invest in residual interest securities issued by tender option bond trusts that may have recourse to the
Trust&#8217;s other assets. In such instances, the Trust may be at risk of loss that exceeds its investment in the residual interest
securities. The Trust will segregate or earmark liquid assets with its custodian on a mark-to-market basis to cover such potential
obligations.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><B>Leverage</B><I>.</I> The Trust currently uses leverage to
seek to enhance returns by investing in residual interest bonds. The Trust will not utilize leverage in excess of 15% of its gross
assets. Residual interest bonds are securities that pay interest at rates that vary inversely with changes in prevailing short-term
tax-exempt interest rates and provide the economic effect of leverage. Although the Trust has no current intention to do so, the
Trust is authorized also to utilize leverage through the issuance of preferred shares and/or borrowings, including the issuance
of debt securities. The Trust may borrow for temporary, emergency or other purposes as permitted by the 1940 Act.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Adviser anticipates that the use of leverage (from residual
interest bonds) may result in higher income to holders of Common Shares (&#8220;Common Shareholders&#8221;) 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. The investment advisory fee paid to Eaton Vance will be calculated on the basis of the
Trust&#8217;s average daily gross assets. &#8220;Gross assets&#8221; of the Trust means total assets of the Trust, including assets

higher when leverage is utilized which may create an incentive for the Adviser to employ leverage. In this regard, holders of debt
or preferred shares do not bear the investment advisory fee. Rather, Common Shareholders bear the portion of the investment advisory

instruments. The Trust will enter into swaps only on a net basis, i.e<I>.</I>, 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. If the other party to a swap defaults,
the Trust&#8217;s risk of loss consists of the net amount of payments that the Trust is contractually entitled to receive that
is in excess of collateral posted by the Trust&#8217;s counterparty in respect of such liability. The net amount of the excess,
if any, of the Trust&#8217;s obligations over its entitlements will be maintained in a segregated account by the Trust&#8217;s
custodian. The Trust will not enter into any swap unless the claims-paying ability of the other party thereto is considered to
be investment grade by the Adviser. If there is a default by the other party to such a transaction, the Trust will have contractual
remedies pursuant to the agreements related to the transaction. Swaps are traded in the over-the-counter market. The use of swaps
is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary
portfolio securities transactions. If the Adviser is incorrect in its forecasts of market values, interest rates and other applicable
factors, the total return performance of the Trust would be unfavorably affected.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Total
Return Swaps. </B></FONT>A total return swap is a contract in which one party agrees to make periodic payments to another party
based on the change in market value of a reference instrument during the specified period, in return for periodic payments from
the other party that are based on a fixed or variable interest rate or the total return of the reference instrument or another
reference instrument. Total return swap agreements may be used to obtain exposure to a security or market without owning or taking
physical custody of such security or investing directly in such market.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Interest
Rate Swaps and Forward Rate Contracts. </B></FONT>Interest rate swaps involve the exchange by the Trust with another party of their
respective commitments to pay or receive interest, <I>e.g.</I>, an exchange of fixed rate payments for floating rate payments.
The Trust will only enter into interest rate swaps on a net basis, <I>i.e., </I>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. The Trust may also enter forward rate contracts.
Under these contracts, the buyer locks in an interest rate at a future settlement date. If the interest rate on the settlement
date exceeds the lock rate, the buyer pays the seller the difference between the two rates. If the lock rate exceeds the interest
rate on the settlement date, the seller pays the buyer the difference between the two rates. Any such gain received by the Trust
would be taxable.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">If the other party to an interest rate swap or forward rate contract
defaults, the Trust&#8217;s risk of loss consists of the net amount of payments that the Trust is contractually entitled to receive
that is in excess of collateral posted by the Trust&#8217;s counterparty in respect of such liability. The net amount of the excess,
if any, of the Trust&#8217;s obligations over its entitlements will be maintained in a segregated account by the

Transactions. </B></FONT>The Trust may purchase and sell various kinds of financial futures contracts and options thereon to seek
to hedge against changes in interest rates or for other risk management or investment purposes. Futures contracts may be based
on various debt securities and securities indices. Such transactions involve a risk of loss or depreciation due to unanticipated
adverse changes in securities prices, which may exceed the Trust&#8217;s initial investment in these contracts. The Trust only
will purchase or sell futures contracts or related options in compliance with the rules of the Commodity Futures Trading Commission.
These transactions involve transaction costs. There can be no assurance that Eaton Vance&#8217;s use of futures will be advantageous
to the Trust. Distributions by the Trust of any gains realized on the Trust&#8217;s transactions in futures and options on futures
will be taxable.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Zero-Coupon
Bonds. </B></FONT>Some of the obligations in which the Trust invests may include so-called &#8220;zero-coupon&#8221; bonds, whose
values generally are subject to greater fluctuation in response to changes in market interest rates than bonds that pay interest
currently. Zero-coupon bonds are issued at a discount from face value and pay interest only at maturity rather than at intervals
during the life of the security. The Trust is required to take into account imputed income from zero-coupon bonds on a current
basis, even though it does not receive that income currently in cash. Because the Trust is required to distribute substantially
all of its income for each taxable year, investments in zero-coupon bonds may require the Trust to sell investments to obtain cash
needed to make income distributions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>When-Issued
Securities. </B></FONT>The Trust may purchase securities on a &#8220;when-issued&#8221; basis, which means that payment and delivery
occur on a future settlement date. The price and yield of such securities are generally fixed on the date of commitment to purchase.
However, the market value of the securities may fluctuate prior to delivery, and upon delivery the securities may be worth more
or less than what the Trust agreed to pay for them. The Trust may be required to maintain a segregated account of liquid assets
equal to outstanding purchase commitments. The Trust may also purchase instruments that give the Trust the option to purchase a
municipal obligation when and if issued.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Investment
Company Securities. </B></FONT>The Trust may purchase common shares of closed-end investment companies that have investment objectives
and policies similar to those of the Trust. In addition to providing tax-exempt income, such securities may provide capital appreciation.
Such investments, which may also be leveraged and subject to similar risks as the Trust, will not exceed 10% of the Trust&#8217;s
gross assets. These companies bear fees and expenses that the Trust will incur indirectly. The Trust will not invest in other investment
companies that are affiliated with Eaton Vance.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Portfolio
Turnover.</B></FONT> The Trust cannot accurately predict its portfolio turnover rate, but its historical annual turnover rate over
the last five years has been between 6% and 44% (excluding turnover of securities and obligations having a maturity of one year
or less). For the fiscal years ended March 31, 2020 and March 31, 2019, the Trust&#8217;s portfolio turnover rates were 44% and
17%, respectively. The Trust may engage in active short-term trading to benefit from yield disparities among different issues,
to seek short-term profits or for other reasons. Such trading will increase the Trust&#8217;s rate of turnover and may increase
the incidence of net short-term capital gains which, upon distribution by the Trust, are taxable to Common Shareholders as ordinary
income.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Restricted
Securities.</B></FONT> Securities held by the Trust may be legally restricted as to resale (such as those issued in private placements),
including commercial paper issued pursuant to Section 4(a)(2) of the 1933 Act and securities eligible for resale pursuant to Rule
144A thereunder, and securities of U.S. and non-U.S. issuers initially offered and sold outside the United States pursuant to Regulation
S thereunder. Restricted securities may not be listed on an exchange and may have no active trading market. The Trust may incur
additional expense when disposing of restricted securities, including all or a portion of the cost to register the securities.
The Trust also may acquire securities through private placements under which it may agree to contractual restrictions on the resale
of such securities that are in addition to applicable legal restrictions. In addition, if the Adviser receives material non-public
information about the issuer, the Trust may as a result be unable to sell the securities. Restricted securities may be difficult
to value properly and may involve greater risks than securities that are not subject to restrictions on resale. It may be difficult
to sell restricted securities at a price representing fair value until such time as the securities may be sold publicly. Under
adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Trust could
find it more difficult to sell such securities when the Adviser believes it advisable to do so or may be able to sell such securities
only at prices lower than if such securities were more widely held. Holdings of restricted securities may increase the level of
Trust illiquidity if eligible buyers become uninterested in purchasing them. Restricted securities may involve a high degree of
business and financial risk, which may result in substantial losses.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Illiquid
Investments.</B></FONT> The Trust may invest in investments for which there is no readily available trading market or that are
otherwise illiquid. It may be difficult to sell illiquid investments at a price representing their fair value until such time as
such investments may be sold publicly. Where registration is required, a considerable period may elapse between a decision by the
Trust to sell the investments and the time when it would be permitted to sell. Thus, the Trust may not be able to obtain as favorable
a price as that prevailing at the time of the decision to sell. The Trust may also acquire investments through private placements
under which it may agree to contractual restrictions on the resale of such investments. Such restrictions might prevent their sale
at a time when such sale would otherwise be desirable.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">At times, a portion of the Trust's assets may be invested
in investments as to which the Trust, by itself or together with other accounts managed by the Adviser and its affiliates, holds
a major portion or all of such investments. Under adverse market or economic conditions or in the event of adverse changes in the
financial condition of the issuer, the Trust could find it more difficult to sell such investments when the Adviser believes it
advisable to do so or may be able to sell such investments only at prices lower than if such investments were more widely held.
It may also be more difficult to determine the fair value of such investments for purposes of computing the Trust's net asset value.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Research
Process.</B></FONT> The Trust&#8217;s portfolio management utilizes the information provided by, and the expertise of, the research
staff of the investment adviser and its affiliates in making investment decisions. As part of the research process, portfolio management
may consider financially material environmental, social and governance (&#8220;ESG&#8221;) factors. Such factors, alongside other
relevant factors, may be taken into account in the Trust&#8217;s securities selection process.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Temporary
Investments.</B></FONT> During unusual market conditions, the Trust may invest up to 100% of its assets in cash or cash equivalents
temporarily, which may be inconsistent with its investment objectives, principal strategies and other policies. Cash equivalents
are highly liquid, short-term securities such as commercial paper, time deposits, certificates of deposit, short-term notes and
short-term United States government obligations. In moving to a substantial temporary investments position and in transitioning
from such a position back into conformity with the Trust&#8217;s normal investment policies, the Trust may incur transaction costs
that would not be incurred if the Trust had remained fully invested in accordance with such normal policies. The transition to
and from a substantial temporary investments position may also result in the Trust having to sell common stocks and/or close out
options positions and then later purchase common stocks and open new options positions in circumstances that might not otherwise
be optimal. The Trust&#8217;s investment in such temporary investments under unusual market circumstances may not be in furtherance
of the Trust&#8217;s investment objectives.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><B>USE OF LEVERAGE AND RELATED RISKS</B></P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">As described herein, the Trust may invest in residual interest
bonds, which have the economic effect of leverage. As of March 31, 2020, the Trust had leverage in the form of residual interest
bonds. The Adviser anticipates that the use of leverage (from investment in residual interest bonds) may result in higher income
to Common 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 successful.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The costs of the financial leverage program (from investment
in residual interest bonds and any borrowings) are borne by Common Shareholders and consequently result in a reduction of the NAV
of Common Shares. During periods in which the Trust is using leverage, the fees paid to Eaton Vance for investment advisory services
will be higher than if the Trust did not use leverage because the fees paid will be calculated on the basis of the Trust&#8217;s
gross assets, which means the total assets of the Trust, including assets attributable to any form of leverage, minus all accrued
expenses incurred in the normal course of operations, but not excluding any liabilities or obligations attributable to leverage
obtained through (i) indebtedness of any type (including, without limitation, borrowing through a credit facility or the issuance
of debt securities), (ii) the issuance of preferred stock or other similar preference securities, (iii) the reinvestment of collateral
received for securities loaned in accordance with the Trust&#8217;s investment objectives and policies, and/or (iv) any other means;
all as determined in accordance with generally accepted accounting principles. In this regard, holders of debt or preferred shares
do not bear the investment advisory fee. Rather, Common Shareholders bear the portion of the investment advisory fee attributable
to the assets purchased with the proceeds, which means that Common Shareholders effectively bear the entire advisory fee.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Leverage creates risks for holders of the Common Shares, including
the likelihood of greater volatility of NAV and market price of the Common Shares. There is a risk that the costs of leverage may
adversely affect the return to the holders of the Common Shares. If the income from the investments purchased with the proceeds
of leverage 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 Common Shareholders will be reduced. The Adviser in its best judgment
nevertheless may determine to maintain the Trust&#8217;s leveraged position if it deems such action to be appropriate in the circumstances.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Changes in the value of the Trust&#8217;s investment portfolio
(including investments bought with the proceeds of leverage) will be borne entirely by the Common Shareholders. If there is a net
decrease (or increase) in the value of the Trust&#8217;s investment portfolio, the leverage will decrease (or increase) the NAV
per Common Share to a greater extent than if the Trust were not leveraged. As discussed under &#8220;Description of Capital Structure,&#8221;
the Trust&#8217;s issuance of any preferred shares may alter the voting power of Common Shareholders.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Capital raised through leverage will be subject to distribution
and/or interest payments, which may exceed the income and appreciation on the assets purchased. The issuance of a class of preferred
shares involves offering expenses and other costs and may limit the Trust&#8217;s freedom to pay distributions on Common Shares
or to engage in other activities. The issuance of a class of preferred shares having priority over the Common Shares creates an
opportunity for greater return per Common Share, but at the same time such leveraging is a speculative technique that will increase
the Trust&#8217;s exposure to capital risk. Unless the income and appreciation, if any, on assets acquired with offering proceeds
exceed the cost of issuing additional classes of securities (and other Trust expenses), the use of leverage will diminish the investment
performance of the Common Shares compared with what it would have been without leverage.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may be subject to certain restrictions on investments
imposed by guidelines of one or more Rating Agencies that may issue ratings for any preferred shares issued by the Trust. Any
bank lender in connection with a credit facility or commercial paper program may also impose specific restrictions as a condition
to borrowing. Such restrictions imposed by a Rating Agency or lender may include asset coverage or portfolio composition requirements
that are more stringent than those imposed on the Trust by the 1940 Act. It is not anticipated that these covenants or guidelines
will significantly impede Eaton Vance from managing the Trust&#8217;s portfolio in accordance with its investment objectives and
policies.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Under the 1940 Act, the Trust is not permitted to issue preferred
shares unless immediately after such issuance the total asset value of the Trust&#8217;s portfolio is at least 200% of the liquidation
value of the outstanding preferred shares plus the amount of any senior security representing indebtedness (i.e., such liquidation
value and amount of indebtedness may not exceed 50% of the Trust&#8217;s total assets). In addition, the Trust is not permitted
to declare any cash distribution on its Common Shares unless, at the time of such declaration, the NAV of the Trust&#8217;s portfolio
(determined after deducting the amount of such distribution) is at least 200% of such liquidation value plus amount of indebtedness.
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%. As of March 31, 2020, the leverage attributable to floating-rate
notes represented 6.89% of the Trust&#8217;s gross assets. Holders of any preferred shares, voting as a class, would be entitled
to elect two of the Trust&#8217;s Trustees. The holders of both the Common Shares and any preferred shares (voting together as
a single class with each share entitling its holder to one vote) would be entitled to elect the remaining Trustees of the Trust.
In the event the Trust fails to pay distributions on its preferred shares for two years, preferred shareholders would be entitled
to elect a majority of the Trustees until the preferred distributions in arrears are paid. The Trust has no current intention to
issue preferred shares.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Under the 1940 Act, the Trust is not permitted to incur indebtedness,
including through the issuance of debt securities, unless immediately thereafter the total asset value of the Trust&#8217;s portfolio
is at least 300% of the liquidation value of the outstanding indebtedness (i.e., such liquidation value may not exceed 33 1/3%
of the Trust&#8217;s total assets). In addition, the Trust is not permitted to declare any cash distribution on its Common Shares
unless, at the time of such declaration, the NAV of the Trust&#8217;s portfolio (determined after deducting the amount of such
distribution) is at least 300% of such liquidation value. If the Trust borrows money or enters into a commercial paper program,
the Trust intends, to the extent possible, to retire outstanding debt, from time to time, to maintain coverage of any outstanding
indebtedness of at least 300%. As of March 31, 2020, there were no outstanding borrowings.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">To qualify for federal income taxation as a &#8220;regulated
investment company,&#8221; the Trust must distribute in each taxable year at least 90% of its net investment income (including
net interest income and net short-term gain). The Trust also will be required to distribute annually substantially all of its income
and capital gain, if any, to avoid imposition of a nondeductible 4% federal excise tax. If the Trust is precluded from making distributions
on the Common Shares because of any applicable asset coverage requirements, the terms of the preferred shares may provide that
any amounts so precluded from being distributed, but required to be distributed for the Trust to meet the distribution requirements
for qualification as a regulated investment company, will be paid to the holders of the preferred shares as a special distribution.
This distribution can be expected to decrease the amount that holders of preferred shares would be entitled to receive upon redemption
or liquidation of the shares.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Successful use of a leveraging strategy may depend on the Adviser&#8217;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.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Residual
Interest Bonds.</B></FONT> Residual interest bonds are securities that pay interest at rates that vary inversely with changes in
prevailing short-term tax-exempt interest rates and provide the economic effect of leverage. In general, income on residual interest
bonds will decrease when short-term interest rates increase and increase when short-term interest rates decrease. Residual interest
bonds have varying degrees of liquidity, and the market for these securities is relatively volatile. Residual interest bonds create
investment leverage in the Trust because they provide more than one dollar of exposure to municipal bonds for each dollar the Trust
invests in them.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may invest in residual interest bonds, also referred
to as inverse floating rate securities, whereby the Trust may sell a variable or fixed rate bond for cash to a SPV, (which is generally
organized as a trust), while at the same time, buying a residual interest in the assets and cash flows of the SPV. The bond is
deposited into the SPV with the same CUSIP number as the bond sold to the SPV by the Trust, and which may have been, but is not
required to be, the bond purchased from the Trust (the &#8220;Bond&#8221;). The SPV also issues Floating Rate Notes which are sold
to third-parties. The residual interest bond held by the Trust gives the Trust the right (1) to cause the holders of the Floating
Rate Notes to generally tender their notes at par, and (2) to have the Bond held by the SPV transferred to the Trust, thereby terminating
the SPV. Should the Trust exercise such right, it would generally pay the SPV the par amount due on the Floating Rate Notes and
exchange the residual interest bond for the underlying Bond. Pursuant to generally accepted accounting principles the Trust accounts
for the transaction described above as a secured borrowing by including the Bond in its portfolio of investments and the Floating
Rate Notes as a liability. The Floating Rate Notes have interest rates that generally reset weekly and their holders have the option
to tender their notes to the SPV for redemption at par at each reset date. The SPV may be terminated by the Trust, as noted above,
or by the occurrence of certain termination events as defined in the trust agreement, such as a downgrade in the credit quality
of the underlying Bond, bankruptcy of or payment failure by the issuer of the underlying Bond, the inability to remarket Floating
Rate Notes that have been tendered due to insufficient buyers in the market, or the failure by the SPV to obtain renewal of the
liquidity agreement under which liquidity support is provided for the Floating Rate Notes up to one year.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In certain circumstances, the Trust may enter into shortfall
and forbearance agreements with respect to a residual interest bond. The Trust generally may enter into such agreements (i) when
the liquidity provider to the SPV requires such an agreement because the level of leverage in the SPV exceeds the level that the
liquidity provider is willing support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing
the SPV in the event that the municipal obligation held in the SPV has declined in value. Such agreements commit the Trust to reimburse,
upon the termination of the SPV, the difference between the liquidation value of the underlying security (which is the basis of
the inverse floater) and the principal amount due to the holders of the floating rate security issued in conjunction with the inverse
floater. Such agreements may expose the Trust&#8217;s other assets to losses. Absent a shortfall and forbearance agreement, the
Trust would not be required to make such a reimbursement. If the Trust chooses not to enter into such an agreement, the inverse
floater could be terminated and the Trust could incur a loss. Consistent with SEC staff guidance, the Trust will segregate or earmark
liquid assets with its custodian on a mark-to-market basis to cover any such payment obligations to liquidity providers. The Trust
had no shortfalls as of March 31, 2020.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may also purchase residual interest bonds in a secondary
market transaction without first owning the underlying bond. Such transactions are not required to be treated as secured borrowings.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust&#8217;s investment policies and restrictions expressly
permit investments in residual interest bonds. Such bonds typically offer the potential for yields exceeding the yields available
on fixed rate bonds with comparable credit quality and maturity. These securities tend to underperform the market for fixed rate
bonds in a rising long-term interest rate environment, but tend to outperform the market for fixed rate bonds when long-term interest
rates decline. The value and income of residual interest bonds are generally more volatile than that of a fixed rate bond. The
Trust&#8217;s investment policies do not allow the Trust to borrow money except as permitted by the 1940 Act. The Adviser believes
that the Trust&#8217;s restrictions on borrowing money and issuing senior securities (other than as specifically permitted) do
not apply to Floating Rate Notes issued by the SPV and included as a liability in the Trust&#8217;s statement of assets and liabilities.

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Risk is inherent in all investing. Investing in any investment
company security involves risk, including the risk that you may receive little or no return on your investment or even that you

From or Premium to NAV.</B></FONT> The Offering will be conducted only when Common Shares of the Trust are trading at a price
equal to or above the Trust&#8217;s NAV per Common Share plus the per Common Share amount of commissions. As with any security,
the market value of the Common Shares may increase or decrease from the amount initially paid for the Common Shares. The Trust&#8217;s
Common Shares have traded both at a premium and at a discount relative to net asset value. The shares of closed-end management
investment companies frequently trade at a discount from their NAV. This is a risk separate and distinct from the risk that the
Trust&#8217;s NAV may decrease.&nbsp;</P>

market for the Common Shares. The increase in the amount of the Trust&#8217;s outstanding Common Shares resulting from the Offering
may put downward pressure on the market price for the Common Shares of the Trust. Common Shares will not be issued pursuant to
the Offering at any time when Common Shares are trading at a price lower than a price equal to the Trust&#8217;s NAV per Common
Share plus the per Common Share amount of commissions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust also issues Common Shares of the Trust through its
dividend reinvestment plan. See &#8220;Dividend Reinvestment Plan.&#8221; Common Shares may be issued under the plan at a discount
to the market price for such Common Shares, which may put downward pressure on the market price for Common Shares of the Trust.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">When the Common Shares are trading at a premium, the Trust may
also issue Common Shares of the Trust that are sold through transactions effected on the NYSE. The increase in the amount of the

and Market Risk.</B></FONT> An investment in Common Shares is subject to investment risk, including the possible loss of the entire
principal amount invested. An investment in Common Shares represents an indirect investment in the securities owned by the Trust,

Interest rate risk is the risk that the municipal obligations in the Trust&#8217;s portfolio will decline in value because of increases
in market interest rates. Generally, obligations with longer durations or maturities are more sensitive to changes in interest
rates than obligations with shorter durations or maturities, causing them to be more volatile. Conversely, obligations with shorter
durations or maturities will be less volatile but may provide lower returns than obligations with longer durations or maturities.
A decline in the prices of the municipal obligations owned by the Trust would cause a decline in the NAV of the Trust, which could

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Trust may utilize certain strategies, including taking positions
in futures or interest rate swaps and forward rate contracts, for the purpose of reducing the interest rate sensitivity of the
portfolio and decreasing the Trust&#8217;s exposure to interest rate risk, although there can be no assurance that it will do so
or that such strategies will be successful.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Because the Trust is managed toward an income objective, it may
hold more longer duration or maturity obligations and thereby be more exposed to interest rate risk than municipal income funds
that are managed with a greater emphasis on total return. Certain factors, such as the presence of call features, may cause a particular
fixed-income security, or the Trust as a whole, to exhibit less sensitivity to changes in interest rates. Certain of the Trust&#8217;s
investments may also be valued, in part, by reference to the relative relationship between interest rates on tax-exempt securities
and taxable securities, respectively. When the market for tax-exempt securities underperforms (or outperforms) the market for taxable
securities, the value of these investments may be negatively affected (or positively affected).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The income investors receive from the Trust is based primarily
on the interest it earns from its investments, which can vary widely over the short- and long-term. If long-term interest rates
drop, investors&#8217; income from the Trust over time could drop as well if the Trust purchases securities with lower interest
coupons.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust invests in residual interest bonds. Compared to similar
fixed-rate municipal bonds, the value of these bonds will fluctuate to a greater extent in response to changes in prevailing long-term
interest rates. Moreover, the income earned on residual interest municipal bonds will fluctuate in response to changes in prevailing
short-term interest rates. Thus, when such bonds are held by the Trust, an increase in short- or long-term market interest rates
may adversely affect the income received from such bonds or the NAV of Trust shares.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Call
and Reinvestment Risks.</B></FONT> If interest rates fall, it is possible that issuers of callable bonds with high interest coupons
will &#8220;call&#8221; (or prepay) their bonds before their maturity date. If a call were exercised by the issuer during a period
of declining interest rates, the Trust would likely replace such called security with a lower yielding security. If that were to
happen, it could decrease the Trust&#8217;s dividends and possibly could affect the market price of Common Shares. Similar risks
exist when the Trust invests the proceeds from matured or traded municipal obligations at market interest rates that are below
the Trust&#8217;s current earnings rate.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Credit
Risk.</B></FONT> Credit risk is the risk that one or more municipal bonds in the Trust&#8217;s portfolio will decline in price,
or fail to pay interest or principal when due, because the issuer of the bond experiences a decline in its financial status. In
general, lower rated municipal bonds carry a greater degree of risk that the issuer will lose its ability to make interest and
principal payments, which could have a negative impact on the Trust&#8217;s NAV or dividends. Securities rated in the fourth highest
category (i.e., Baa by Moody&#8217;s or BBB by S&amp;P or Fitch) are considered investment grade quality, but may have speculative
characteristics. Municipal obligations may be insured as to principal and interest payments. If the claims paying ability or other
rating of the insurer is downgraded by a rating agency, the value of such obligations may be negatively affected. The Trust is
also exposed to credit risk when it engages in certain types of derivatives transactions and when it engages in transactions that
expose the Trust to counterparty risk. See &#8220;Derivatives Risk.&#8221;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Changes in the credit quality of the issuers of municipal
obligations held by the Trust will affect the principal value of (and possibly the income earned on) such obligations. The credit
quality of an issuer of municipal obligations may be affected by a variety of factors, including the issuer&#8217;s tax base, the
extent to which the issuer relies on federal or state aid, limitations on the taxing power of the issuer and changes in general
economic conditions. Changes by Rating Agencies in their ratings of a security and in the ability of the issuer to make payments
of principal and interest may also affect the value of the Trust&#8217;s investments. The amount of information about the financial
condition of an issuer of municipal obligations may not be as extensive as that made available by corporations whose securities
are publicly traded. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In evaluating the quality of a particular instrument, Eaton
Vance may take into consideration, among other things, a credit rating assigned by a credit rating agency, the issuer&#8217;s financial
resources and operating history, its sensitivity to economic conditions and trends, the ability of its management, its debt maturity
schedules and borrowing requirements, and relative values based on anticipated cash flow, interest and asset coverage, and earnings
prospects. Credit rating agencies are private services that provide ratings of the credit quality of certain investments. Credit
ratings issued by rating agencies are based on a number of factors including, but not limited to, the issuer&#8217;s financial
condition and the rating agency&#8217;s credit analysis, if applicable, at the time of rating. As such, the rating assigned to
any particular security is not necessarily a reflection of the issuer&#8217;s current financial condition. The ratings assigned
are not absolute standards of credit quality and do not evaluate market risks or necessarily reflect the issuer&#8217;s current
financial condition or the volatility or liquidity of the security. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">For purposes of determining compliance with the Trust&#8217;s
credit quality restrictions, Eaton Vance relies primarily on the ratings assigned by credit rating agencies but may, in the case
of unrated instruments, perform its own credit and investment analysis to determine an instrument&#8217;s credit quality. A credit
rating may have a modifier (such as plus, minus or a numerical modifier) to denote its relative status within the rating. The
presence of a modifier does not change the security credit rating (for example, BBB- and Baa3 are within the investment grade
rating) for purposes of the Trust&#8217;s investment limitations. If an instrument is rated differently by two or more rating
agencies, the highest rating will be used for purposes of the Trust&#8217;s rating restrictions. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may invest in unrated obligations for which Eaton Vance
will make a credit quality determination for purposes of the Trust&#8217;s credit quality policy. To the extent that the Trust
invests in such unrated obligations, the Trust&#8217;s credit quality will be more dependent on Eaton Vance&#8217;s credit analysis
than if the Trust invested in only rated obligations.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may invest in MLOs and certificates of participation.
The obligation of the issuer to meet its obligations under such instruments is often subject to the ongoing appropriation by a
legislative body, on an annual or other basis, of funds for the payment of the obligations. Investments in municipal leases are
thus subject to the risk that the legislative body will not make the necessary appropriation and the issuer will not otherwise
be willing or able to meet its obligation.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Liquidity
Risk.</B></FONT> The secondary market for some municipal obligations is less liquid than that for widely traded taxable debt obligations
or widely traded municipal obligations. No established resale market exists for certain of the municipal obligations in which the
Trust may invest. The Trust has no limitation on the amount of its assets that may be invested in securities that are not readily
marketable or are subject to restrictions on resale. In certain situations, the Trust could find it more difficult to sell such
securities at desirable times and/or prices. The Trust may not be able to readily dispose of such securities at prices that approximate
those at which the Trust could sell such securities if they were more widely traded or at which the Trust has valued such securities
and, as a result of such illiquidity, the Trust may have to sell other investments or engage in borrowing transactions if necessary
to raise cash to meet its obligations. In addition, the limited liquidity could affect the market price of the securities, thereby
adversely affecting the Trust&#8217;s NAV and ability to make distributions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Municipal
Bond Market Risk.</B></FONT> Investing in the municipal bond market involves certain risks. Certain securities in which the Trust
will invest will not be registered with the SEC or any state securities commission and will not be listed on any national securities
exchange. The amount of public information available about the municipal obligations in the Trust&#8217;s portfolio is generally
less than for corporate equities or bonds, and the investment performance of the Trust may, therefore, be more dependent on the
analytical abilities of Eaton Vance than if the Trust were a stock fund or taxable bond fund.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The ability of municipal issuers to make timely payments of interest
and principal may be diminished during general economic downturns and as governmental cost burdens are reallocated among federal,
state and local governments. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend
the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations, or on the ability
of municipalities to levy taxes. Issuers of municipal obligations might seek protection under the bankruptcy laws. In the event
of bankruptcy of an issuer, the Trust could experience delays in collecting principal and interest to which it is entitled, and
may obtain only a limited recovery or no recovery in such circumstances. To enforce its rights in the event of default in the payment
of interest or repayment of principal, or both, the Trust may take possession of and manage the assets securing the issuer&#8217;s
obligations on such securities, which may increase the Trust&#8217;s operating expenses. Any income derived from the Trust&#8217;s
ownership or operation of such assets may not be tax-exempt.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The value of municipal securities generally may be affected by
uncertainties in the municipal markets as a result of legislation or litigation, including legislation or litigation that changes
the taxation of municipal securities or the rights of municipal security holders in the event of a bankruptcy. Certain provisions
of the U.S. Bankruptcy Code governing such bankruptcies are unclear. Further, the application of state law to municipal security
issuers could produce varying results among the states or among municipal security issuers within a state. These uncertainties
could have a significant impact on the prices of the municipal securities in which the Trust invests.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">If the number of municipal borrowers and the amount of outstanding
municipal securities contract, without corresponding reductions in investor demand for municipal securities, the Trust may have
fewer investment alternatives, may invest in securities that it previously would have declined and may concentrate its investments

Investment Grade Securities Risk</B></FONT>. Up to 30% of the Trust&#8217;s investments in municipal obligations may be, at the
time of investment, rated below investment grade or if unrated deemed by the Adviser to be below investment grade. Such obligations
are commonly called &#8220;junk bonds&#8221; and will have speculative characteristics in varying degrees. While such obligations
may have some quality and protective characteristics, these characteristics can be expected to be offset or outweighed by uncertainties
or major risk exposures to adverse conditions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Below investment grade municipal obligations involve a greater
degree of credit, interest rate and market risk than investment grade municipal obligations. Below investment grade municipal obligations

also be subject to greater price volatility due to such factors as interest rate sensitivity, market perception of the creditworthiness
of the issuer and general market liquidity. Below investment grade municipal obligations are considered predominantly speculative

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">investment grade municipal obligations typically entail greater
potential price volatility and may be less liquid than investment grade municipal obligations. Issuers of below investment grade
municipal obligations are more likely to default on their payments of interest and principal owed to the Trust, and such defaults
will reduce the Trust&#8217;s NAV and income distributions. The prices of these below investment grade obligations are more sensitive
to negative developments than higher rated securities. Adverse economic conditions generally lead to a higher non-payment rate.
In addition, below investment grade municipal obligations may lose significant value before a default occurs as the market adjusts
to expected higher non-payment rates.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Increases in interest rates and changes in the economy may adversely
affect the ability of issuers of lower grade municipal obligations to pay interest and to repay principal, to meet projected financial
goals and to obtain additional financing. Issuers of below investment grade municipal obligations may be more adversely affected
by a prolonged recession or continued deterioration of economic conditions. In the event that an issuer of securities held by the
Trust experiences difficulties in the timely payment of principal or interest and such issuer seeks to restructure the terms of
its borrowings, the Trust may incur additional expenses and may determine to invest additional assets with respect to such issuer
or the project or projects to which the Trust&#8217;s portfolio securities relate. Further, the Trust may incur additional expenses
to the extent that it is required to seek recovery upon a default in the payment of interest or the repayment of principal on its
portfolio holdings, and the Trust may be unable to obtain full recovery thereof. When the Trust invests in lower rated or unrated
municipal obligations, the achievement of the Trust&#8217;s investment objectives is more dependent on the Adviser&#8217;s credit
analysis than would be the case if the Trust were investing in municipal obligations rated investment grade.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">To the extent that there is no established market for some of
the lower grade municipal obligations in which the Trust may invest, trading in such securities may be relatively inactive. The
Adviser is responsible for determining the NAV of the Trust, subject to the supervision of the Trust&#8217;s Board. During periods
of reduced market liquidity and in the absence of readily available market quotations for lower grade municipal obligations held
in the Trust&#8217;s portfolio, the ability of the Adviser to value the Trust&#8217;s securities becomes more difficult and the
Adviser&#8217;s use of judgment may play a greater role in the valuation of the Trust&#8217;s securities due to the reduced availability
of reliable objective data. The effects of adverse publicity and investor perceptions may be more pronounced for securities for
which no established market exists as compared with the effects on securities for which a regular market does exist. Further, the
Trust may have more difficulty selling such securities in a timely manner and at their stated value than would be the case for
securities for which an established market does exist.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Municipal obligations held by the Trust that are initially rated
below investment grade may subsequently be determined by the Adviser to be of investment grade quality for purposes of the Trust&#8217;s
investment policies if the securities subsequently are backed by escrow accounts containing U.S. Government obligations. The Trust
may retain in its portfolio an obligation that declines in quality, including defaulted obligations, if such retention is considered
desirable by the Adviser. In the case of a defaulted obligation, the Trust may incur additional expense seeking recovery of its
investment.</P>

Risk.</B></FONT> Municipal obligations may be insured as to their scheduled payment of principal and interest. Although the insurance
feature may reduce some financial risks, the premiums for insurance and the higher market price sometimes paid for insured obligations
may reduce the current yield on the insured obligation. Insured obligations also may be secured by bank credit agreements or escrow
accounts. Changes in the ratings of an insurer may affect the value of an insured obligation, and in some cases may even cause
the value of a security to be less than a comparable uninsured obligation. The insurance does not guarantee the market value of
the insured obligation or the net asset value of the Trust&#8217;s shares. If a municipal obligation is insured, the Trust will
use the higher of the Municipal Obligation Rating or the insurance issuer&#8217;s rating. The obligation of a municipal bond insurance
company to pay a claim extends over the life of each insured obligation. Although defaults on insured municipal obligations have
been low to date and municipal bond insurers have met their claims, there is no assurance this will continue. A higher than expected
default rate could strain the insurer&#8217;s loss reserves and adversely affect its ability to pay claims to bondholders. Because
a significant portion of insured municipal obligations that have been issued and are outstanding is insured by a small number of
insurance companies, an event involving one or more of these insurance companies, such as a credit rating downgrade, could have
a significant adverse effect on the value of the municipal obligations insured by that insurance company and on the municipal bond
markets as a whole.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The U.S. and non-U.S. derivatives markets have undergone substantial
changes in recent years as a result of changes under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the &#8220;Dodd-Frank
Act&#8221;) in the United States and regulation changes in Europe, Asia and other non-U.S. jurisdictions. In particular, the Dodd-Frank
Act and related regulations require many derivatives to be cleared and traded on an exchange, expand entity registration requirements,
impose business conduct requirements on counterparties, and impose other regulatory requirements that will continue to change derivatives
markets as regulations are implemented. Additional future regulation of the derivatives markets may make the use of derivatives
more costly, may limit the availability or reduce the liquidity of derivatives, and may impose limits or restrictions on the counterparties
with which the Trust engages in derivative transactions. Trust management cannot predict the effects of any new governmental regulation
that may be implemented, and future regulation may impair the effectiveness of the Trust&#8217;s derivative transactions and its
ability to achieve its investment objectives.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">At any time after the date of this prospectus, legislation
may be enacted that could negatively affect the assets of the Trust. Legislation or regulation may change the way in which the
Trust itself is regulated. The Adviser cannot predict the effects of any new governmental regulation that may be implemented,
and there can be no assurance that any new governmental regulation will not adversely affect the Trust&#8217;s ability to achieve
its investment objectives.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>State
Specific Risk.</B></FONT> If the Trust focuses its investments in any one state (or U.S. territory), the Trust may be more susceptible
to adverse economic, political or regulatory occurrences affecting a particular state (or territory). Certain municipal bond issuers
in Puerto Rico have recently experienced financial difficulties and rating agency downgrades, and two such issuers have defaulted
on their payment obligations.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Up to 5% of the Trust&#8217;s investments in municipal obligations
may be collateralized by the proceeds from class action or other litigation against the tobacco industry. Such municipal obligations
are backed solely by expected revenues to be derived from lawsuits involving tobacco-related deaths and illnesses which were settled
between certain states and American tobacco companies. Tobacco settlement bonds are secured by an issuing state&#8217;s proportionate
share in the Master Settlement Agreement (&#8220;MSA&#8221;). The MSA is an agreement, reached out of court in November 1998 between
46 states and nearly all of the major U.S. tobacco manufacturers. Under the terms of the MSA, the actual amount of future settlement
payments by tobacco manufacturers is dependent on many factors, including, but not limited to, annual domestic cigarette shipments,
reduced cigarette consumption, increased taxes on cigarettes, inflation, financial capability of tobacco companies, continuing
litigation and the possibility of tobacco manufacturer bankruptcy. Payments made by tobacco manufacturers could be negatively impacted
if the decrease in tobacco consumption is significantly greater than the forecasted decline. See &#8220;State Specific Investments&#8221;
in the SAI for additional information about tobacco settlement bonds and the MSA.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Residual
Interest Bond Risk.</B></FONT> Residual interest bonds are residual interests of a SPV that holds municipal obligations. Residual
interest bonds pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and provide
the economic effect of leverage. The interest rate payable on a residual interest bond also bears an inverse relationship to the
interest rate on floating rate notes issued by the SPV (&#8220;Floating Rate Notes&#8221;). Because changes in the interest rate
on the Floating Rate Notes inversely affect the interest paid on the residual interest bond, the value and income of a residual
interest bond is generally more volatile than that of a fixed rate bond. Residual interest bonds have interest rate adjustment
formulas that generally reduce or, in the extreme, eliminate the interest paid to the Trust when short-term interest rates rise,
and increase the interest paid to the Trust when short-term interest rates fall. Residual interest bonds have varying degrees of
liquidity, and the market for these securities is relatively volatile. These securities tend to underperform the market for fixed
rate bonds in a rising long-term interest rate environment, but tend to outperform the market for fixed rate bonds when long-term
interest rates decline. Although volatile, residual interest bonds typically offer the potential for yields exceeding the yields
available on fixed rate bonds with comparable credit quality and maturity. These securities usually permit the investor to convert
the floating rate to a fixed rate (normally adjusted downward), and this optional conversion feature may provide a partial hedge
against rising rates if exercised at an opportune time. While residual interest bonds expose the Trust to leverage risk because
they provide two or more dollars of bond market exposure for every dollar invested, they are not subject to the Trust&#8217;s restrictions
on borrowings.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Any economic effect of leverage through the Trust&#8217;s
purchase of residual interest bonds will create an opportunity for increased Common Share net income and returns, but will also
create the possibility that the Trust&#8217;s long-term returns will be diminished if the cost of leverage exceeds the return on
the bonds purchased with leverage by the Trust. The amount of fees paid to Eaton Vance for investment advisory services will be
higher if the Trust uses financial leverage because the fees will be calculated based on the Trust&#8217;s average daily gross
assets, which may create a conflict of interest between Eaton Vance and the Common Shareholders. &#8220;Gross assets&#8221; of
the Trust means the total assets of the Trust, including assets attributable to any form of leverage, minus all accrued expenses
incurred in the normal course of operations, but not excluding any liabilities or obligations attributable to leverage. See &#8220;Investment
Objectives, Policies and Risks &#8211; Risk Considerations &#8211; Leverage Risk.&#8221;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">A SPV typically can be collapsed or closed by the holder of the
residual interest bonds (such as the Trust) or by the liquidity provider. In certain circumstances, the Trust may enter into shortfall
and forbearance agreements with respect to a residual interest bond. The Trust generally may enter into such agreements (i) when
the liquidity provider to the SPV requires such an agreement because the level of leverage in the SPV exceeds the level that the
liquidity provider is willing support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing
the SPV in the event that the municipal obligation held in the SPV has declined in value. Such agreements commit the Trust to reimburse,
upon the termination of the SPV, the difference between the liquidation value of the underlying security (which is the basis of
the inverse floater) and the principal amount due to the holders of the floating rate security issued in conjunction with the inverse
floater. Such agreements may expose the Trust&#8217;s other assets to losses. Absent a shortfall and forbearance agreement, the
Trust would not be required to make such a reimbursement. If the Trust chooses not to enter into such an agreement, the inverse
floater could be terminated and the Trust could incur a loss. Consistent with SEC staff guidance, the Trust will segregate or earmark
liquid assets with its custodian on a mark-to-market basis to cover any such payment obligations to liquidity providers.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">On December 10, 2013, five U.S. federal agencies published final
rules implementing section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the &#8220;Volcker Rule&#8221;).
The Volcker Rule prohibits banking entities from engaging in proprietary trading of certain instruments and limits such entities&#8217;
investments in, and relationships with, covered funds, as defined in the rules. The Volcker Rule precludes banking entities and
their affiliates from (i) sponsoring residual interest bond programs as presently structured and (ii) continuing relationships
with or services for existing residual interest bond programs. The effects of the Volcker Rule may make it more difficult for the
Trust to maintain current or desired levels of income.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Risks
of MLOs and Certificates of Participation</B></FONT>. The Trust may invest in MLOs and certificates of participation that involve
special risks not normally associated with general obligations or revenue obligations. A MLO is a bond that is secured by lease
payments made by the party, typically a state or municipality, leasing the facilities (e.g., schools or office buildings) that
were financed by the bond. Such lease payments may be subject to annual appropriation or may be made only from revenues associated
with the facility financed. In other cases, the leasing state or municipality is obligated to appropriate funds from its general
tax revenues to make lease payments as long as it utilizes the leased property. A certificate of participation (also referred to
as a &#8220;participation&#8221;) in a municipal lease is an instrument evidencing a pro rata share in a specific pledged revenue
stream, usually lease payments by the issuer . The issuer&#8217;s obligations under such instruments are often subject to the ongoing
appropriation by a legislative body, on an annual or other basis, of funds for the payment thereof. Investments in MLOs and certificates
of participation are therefore typically subject to the risk that the legislative body will not make the necessary annual appropriation
and the issuer will not otherwise be willing or able to meet its obligation.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Inflation
Risk/Deflation Risk. </B></FONT>Inflation risk is the risk that the value of assets or income from investment will be worth less
in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Shares and distributions
thereon can decline. In addition, during periods of rising inflation, short-term interest rates and the Trust&#8217;s cost of leverage
would likely increase, reducing returns to Common Shareholders to the extent that such increased cost is not offset by commensurately
higher income. Deflation risk is the risk that prices throughout the economy decline over time &#8722; the opposite of inflation.
Deflation may have an adverse affect on the creditworthiness of issuers and may make issuer defaults more likely, which may result
in a decline in the value of the Trust&#8217;s investments.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Leverage
Risk.</B></FONT> The Trust will not utilize leverage in excess of 15% of its gross assets. As discussed above, the Trust currently
uses leverage created by investing in residual interest bonds. The Trust will comply with the asset segregation requirements of
the 1940 Act in making such investments. Residual interest bonds are securities that pay interest at rates that vary inversely
with changes in prevailing short-term interest rates and provide the economic effect of leverage. Although the Trust has no current
intention to do so, the Trust is authorized to utilize leverage through the issuance of preferred shares and/or borrowings, including
the issuance of debt securities. The Trust may borrow for temporary, emergency or other purposes as permitted by the 1940 Act.
There can be no assurance that a leveraging strategy will be successful during any period in which it is employed.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Adviser anticipates that the use of leverage (from residual
interest bonds) may result in higher income to Common Shareholders over time. Leverage creates risks for Common Shareholders, including
the likelihood of greater volatility of NAV and market price of the Common Shares and the risk that fluctuations in the costs of
leverage may affect the return to Common Shareholders. To the extent the income derived from investments purchased with funds received
from leverage exceeds the cost of leverage, the Trust&#8217;s distributions will be greater than if leverage had not been used.
Conversely, if the income from the investments purchased with such funds is not sufficient to cover the cost of leverage, the amount
available for distribution to Common Shareholders will be less than if leverage had not been used. In the latter case, Eaton Vance,
in its best judgment, may nevertheless determine to maintain the Trust&#8217;s leveraged position if it deems such action to be
appropriate. There can be no assurance that a leveraging strategy will be successful.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">As discussed under &#8220;Management of the Trust,&#8221; the
investment advisory fee paid to Eaton Vance is calculated on the basis of the Trust&#8217;s average daily gross assets. &#8220;Gross
assets&#8221; of the Trust shall mean total assets of the Trust, including assets attributable to any form of leverage, minus all
accrued expenses incurred in the normal course of operations, but not excluding any liabilities or obligations attributable to
leverage obtained through (i) indebtedness of any type (including, without limitation, borrowing through a credit facility or the
issuance of debt securities), (ii) the issuance of preferred stock or other similar preference securities, (iii) the reinvestment
of collateral received for securities loaned in accordance with the Trust&#8217;s investment objectives and policies, and/or (iv)
any other means; all as determined in accordance with generally accepted accounting principles. This means that the Trust&#8217;s
advisory fees will be higher when leverage is utilized which may create an incentive for the Adviser to employ leverage. In this
regard, holders of any preferred shares do not bear the investment advisory fee. Rather, Common Shareholders bear the portion of
the investment advisory fee attributable to the assets purchased with the proceeds of the use of leverage, which means that Common
Shareholders effectively bear the entire advisory fee.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Financial leverage may also be achieved through the purchase
of certain derivative instruments. The Trust&#8217;s use of derivative instruments exposes the Trust to special risks. See &#8220;Investment
Objectives, Policies and Risks &#8211; Additional Investment Practices&#8221; and &#8220;Investment Objectives, Policies and Risks
&#8211; Additional Risk Considerations.&#8221;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Derivatives
Risk.</B></FONT> In addition to investing in residual interest bonds, the Trust may invest without limitation in other derivative
instruments (which are instruments that derive their value from a reference instrument) acquired for hedging purposes or investment
purposes, such as financial futures contracts and related options, interest rate, total return and other swaps and forward rate
contracts. Depending on the type of derivative instrument and the Trust&#8217;s investment strategy, a reference instrument could
be a security, instrument, index, currency, commodity, economic indicator or event (&#8220;reference instruments&#8221;). The loss
on derivative instruments (other than purchased options) may substantially exceed amounts invested in these instruments. Derivative
transactions, including options on securities and securities indices and other transactions in which the Trust may invest may subject
the Trust to increased risk of principal loss due to unexpected movements in securities prices and interest rates, and imperfect
correlations between the Trust&#8217;s securities holdings and indices upon which derivative transactions are based. Derivatives
can be illiquid, may disproportionately increase losses, and may have a potentially large impact on the Trust&#8217;s performance.
Use of derivative instruments may cause the realization of higher amounts of short-term capital gains (generally taxed at ordinary
income tax rates) than if such instruments had not been used. Trust obligations created pursuant to derivative instruments may
give rise to leverage, which would subject the Trust to increased leverage risk. The Trust also will be subject to credit risk
with respect to the counterparties to any OTC derivatives contracts entered into by the Trust. If a counterparty becomes bankrupt
or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Trust may experience
significant delays in obtaining any recovery under the derivative contract in a bankruptcy or other reorganization proceeding.
The Trust may obtain only a limited recovery or no recovery in such circumstances.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The use of derivatives to enhance income is considered to
be speculative in nature. The use of derivatives may result in greater losses than if they had not been used, may require the Trust
to sell or purchase portfolio investments at inopportune times or for prices other than current market value, may limit the amount
of appreciation the Trust can realize on an investment or may cause the Trust to hold a security it might otherwise sell. Segregated
liquid assets, amounts paid by the Trust as premiums and cash or other assets held in margin accounts with respect to derivatives
transactions are not otherwise available to the Trust for investment or operational purposes. Certain derivative transactions may
have economic characteristics similar to leverage. See &#8220;Additional Risk Considerations - Leverage Risk.&#8221;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The U.S. and non-U.S. derivatives markets have undergone substantial
changes in recent years as a result of changes under the Dodd-Frank Act in the United States and regulation changes in Europe,
Asia and other non-U.S. jurisdictions. In particular, the Dodd-Frank Act and related regulations require many derivatives to be
cleared and traded on an exchange, expand entity registration requirements, impose business conduct requirements on counterparties,
and impose other regulatory requirements that will continue to change derivatives markets as regulations are implemented. Additional
future regulation of the derivatives markets may make the use of derivatives more costly, may limit the availability or reduce
the liquidity of derivatives, and may impose limits or restrictions on the counterparties with which the Trust engages in derivative
transactions. Trust management cannot predict the effects of any new governmental regulation that may be implemented, and future
regulation may impair the effectiveness of the Trust&#8217;s derivative transactions and its ability to achieve its investment
objectives.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Counterparty
Risk. </B></FONT>Changes in the credit quality of the companies that serve as the Trust&#8217;s counterparties with respect to
its derivatives positions and liquidity providers for the Trust&#8217;s residual interest bonds or other investments supported
by another party&#8217;s credit will affect the value of those instruments. Certain entities that have served as counterparties
in the municipals markets have in the past incurred significant financial hardships including bankruptcy and material loss of credit
standing as a result of exposure to investments that have experienced defaults or otherwise suffered extreme credit deterioration.
As a result, such hardships reduced these entities&#8217; capital and called into question their continued ability to perform their obligations. By using derivatives or other instruments
that expose the Trust to counterparties, the Trust assumes the risk that its counterparties could experience future financial hardship.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The counterparty risk for cleared derivatives is generally
lower than for uncleared over-the-counter derivative transactions since generally a clearing organization becomes substituted for
each counterparty to a cleared derivative contract and, in effect, guarantees the parties&#8217; performance under the contract
as each party to a trade looks only to the clearing organization for performance of financial obligations under the derivative
contract. However, there can be no assurance that a clearing organization, or its members, will satisfy its obligations to the
Trust.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Tax
Risk.</B></FONT> The value of the Trust&#8217;s investments and its NAV may be adversely affected by changes in tax rates and policies.
Because interest income from municipal obligations normally is not subject to regular federal income taxation, the attractiveness
of municipal obligations in relation to other investment alternatives is affected by changes in federal income tax rates or changes
in the tax-exempt status of interest income from municipal obligations. From time to time proposals have been introduced before
Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on certain types of municipal
obligations, and it can be expected that similar proposals may be introduced in the future. Any proposed or actual changes in such
rates or exempt status, therefore, can significantly affect the demand for and supply, liquidity and marketability of municipal
obligations. This could, in turn, affect the Trust&#8217;s NAV and ability to acquire and dispose of municipal obligations at desirable
yield and price levels. The Trust is not a suitable investment for individual retirement accounts, for other tax-exempt or tax-deferred
accounts or for investors who are otherwise indifferent to the federal income tax consequences of their investments. See &#8220;Distributions&#8221;
and &#8220;Federal income tax matters.&#8221;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust will invest in municipal obligations in reliance at
the time of purchase on an opinion of bond counsel to the issuer that the interest paid on those securities will be excludable
from gross income under the regular federal income tax, and the Adviser will typically not independently verify that opinion. Subsequent
to the Trust&#8217;s acquisition of such a municipal security, however, the security may be determined to pay, or to have paid,
taxable income. As a result, the treatment of dividends previously paid or to be paid by the Trust as &#8220;exempt-interest dividends&#8221;
could be adversely affected, subjecting the Trust&#8217;s Common Shareholders to increased federal income tax liabilities.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Interest income from certain types of municipal obligations

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Futures
Risk.</B></FONT> Although some futures contracts call for making or taking delivery of the underlying reference instrument, generally
these obligations are closed out prior to delivery by offsetting purchases or sales of matching futures contracts (same exchange,
underlying security or index, and delivery month). Closing a futures contract sale is effected by purchasing a futures contract
for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If an offsetting
purchase price is less than the original sale price, the Trust realizes a capital gain, or if it is more, the Trust realizes a
capital loss. Conversely, if an offsetting sale price is more than the original purchase price, the Trust realizes a capital gain,
or if it is less, the Trust realizes a capital loss. The Adviser has claimed an exclusion from the definition of a Commodity Pool
Operator (&#8220;CPO&#8221;) under the Commodity Exchange Act with respect to the Trust and therefore, neither the Adviser nor

the success of the Trust depends upon the investment skills and analytical abilities of Eaton Vance and the individual portfolio

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Cybersecurity
Risk.</B></FONT> With the increased use of technologies by Trust service providers to conduct business, such as the Internet, the
Trust is susceptible to operational, information security and related risks. The Trust relies on communications technology, systems,
and networks to engage with clients, employees, accounts, shareholders, and service providers, and a cyber incident may inhibit
the Trust&#8217;s ability to use these technologies. In general, cyber incidents can result from deliberate attacks or unintentional
events. Cyber attacks include, but are not limited to, gaining unauthorized access to digital systems (e.g., through &#8220;hacking&#8221;
or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational
disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing
denial-of-service attacks on websites. A denial-of-service attack is an effort to make network services unavailable to intended
users, which could cause shareholders to lose access to their electronic accounts, potentially indefinitely. Employees and service
providers also may not be able to access electronic systems to perform critical duties for the Trust, such as trading and NAV calculation,
during a denial-of-service attack. There is also the possibility for systems failures due to malfunctions, user error and misconduct
by employees and agents, natural disasters, or other foreseeable and unforeseeable events.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Because technology is consistently changing, new ways to carry
out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for,
or that an attack may not be detected, which puts limitations on the Trust&#8217;s ability to plan for or respond to a cyber attack.
Like other Trusts and business enterprises, the Trust and its service providers have experienced, and will continue to experience,
cyber incidents consistently. In addition to deliberate cyber attacks, unintentional cyber incidents can occur, such as the inadvertent
release of confidential information by the Trust or its service providers. To date, cyber incidents have not had a material adverse
effect on the Trust&#8217;s business operations or performance.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust uses third party service providers who are also
heavily dependent on computers and technology for their operations. Cybersecurity failures or breaches by the Trust&#8217;s investment
adviser or administrator and other service providers (including, but not limited to, the custodian or transfer agent), and the
issuers of securities in which the Trust invests, may disrupt and otherwise adversely affect their business operations. This may
result in financial losses to the Trust, impede Trust trading, interfere with the Trust&#8217;s ability to calculate its NAV, or
cause violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other
compensation costs, litigation costs, or additional compliance costs. While many of the Trust service providers have established
business continuity plans and risk management systems intended to identify and mitigate cyber attacks, there are inherent limitations
in such plans and systems including the possibility that certain risks have not been identified. The Trust cannot control the cybersecurity
plans and systems put in place by service providers to the Trust and issuers in which the Trust invests. The Trust and its shareholders
could be negatively impacted as a result.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Other
Investment Companies Risk.</B></FONT> The Trust may, subject to the limitations of the 1940 Act, invest in the securities of other
investment companies. Such securities may be leveraged. As a result, the Trust may be indirectly exposed to leverage through an
investment in such securities. Utilization of leverage is a speculative investment technique and involves certain risks. The Trust,
as a holder of the securities of other investment companies, will bear its pro rata portion of the other investment companies&#8217;
expenses, including advisory fees. These expenses are in addition to the direct expenses of the Trust&#8217;s own operations.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Market
Disruption.</B></FONT> Global instability, war, geopolitical tensions and terrorist attacks in the United States and around the
world have previously resulted, and may continue to result in market volatility and may have long-term effects on the United States
and worldwide financial markets and may cause further economic uncertainties in the United States and worldwide. The Trust cannot
predict the effects of significant future events on the global economy and securities markets. A similar disruption of the financial
markets could impact interest rates, auctions, secondary trading, ratings, credit risk, inflation and other factors relating to
the Common Shares.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Swaps
Risk.</B></FONT> Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging
from a few weeks to more than one year. In a standard &#8220;swap&#8221; transaction, two parties agree to exchange the returns
(or differentials in rates of return) earned or realized on a particular predetermined reference instrument or instruments, which
can be adjusted for an interest rate factor. The gross returns to be exchanged or &#8220;swapped&#8221; between the parties are
generally calculated with respect to a &#8220;notional amount&#8221; (i.e., the return on or increase in value of a particular
dollar amount invested at a particular interest rate or in a &#8220;basket&#8221; of securities representing a particular index).
Other types of swap agreements may calculate the obligations of the parties to the agreement on a &#8220;net basis.&#8221; Consequently,
a party&#8217;s current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid
or received under the agreement based on the relative values of the positions held by each party to the agreement (the &#8220;net
amount&#8221;). <FONT STYLE="font-family: Arial, Helvetica, Sans-Serif; font-weight: normal">Whether the use of swap agreements
will be successful will depend on the Adviser&#8217;s ability to predict correctly whether certain types of reference instruments
are likely to produce greater returns than other instruments. Swap agreements may be subject to contractual restrictions on transferability
and termination and they may have terms of greater than seven days. The Trust&#8217;s obligations under a swap agreement will be
accrued daily (offset against any amounts owed to the Trust under the swap). Developments in the swaps market, including potential
government regulation, could adversely affect the Trust&#8217;s ability
to terminate existing swap agreements or to realize amounts to be received under such agreements, as well as to participate in
swap agreements in the future. If there is a default by the counterparty to a swap, the Trust will have contractual remedies pursuant
to the swap agreement, but any recovery may be delayed depending on the circumstances of the default.</FONT></P>

These risks include interest rate risk, credit risk and liquidity risks as discussed above.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Hedging
Risk.</B></FONT> The Trust&#8217;s use of derivatives or other transactions to reduce risks involves costs and will be subject
to Eaton Vance&#8217;s ability to predict correctly changes in the relationships of such hedge instruments to the Trust&#8217;s
portfolio holdings or other factors. No assurance can be given that Eaton Vance&#8217;s judgment in this respect will be correct.
In addition, no assurance can be given that the Trust will enter into hedging or other transactions at times or under circumstances
in which it may be advisable to do so. Hedging transactions have risks, including the imperfect correlation between the value of
such instruments and the underlying assets of the Trust, which creates the possibility that the loss on such instruments may be
greater than the gain, if any, in the value of the underlying asset in the Trust&#8217;s portfolio; the limited availability of
such instruments; the loss of principal; the possible default of the other party to the transaction; illiquidity of the derivative
investments; and the imperfect correlation between the tax-exempt and taxable markets. Furthermore, the ability to successfully
use hedging transactions depends on the Eaton Vance&#8217;s ability to predict pertinent market movements, which cannot be assured.
Thus, the use of hedging transactions may result in losses greater than if they had not been used, may require the Trust to sell
or purchase portfolio investments at inopportune times or for prices other than current market values, may limit the amount of
appreciation the Trust can realize on an investment, or may cause the Trust to hold a security that it might otherwise sell.</P>

Provisions.</B></FONT> The Trust&#8217;s Agreement and Declaration of Trust includes provisions that could have the effect of limiting
the ability of other persons or entities to acquire control of the Trust or to change the composition of its Board. These provisions

to distribute any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss). To the
extent that the Trust&#8217;s net investment income and net capital gain for any year exceed the total monthly distributions paid
during the year, the Trust will make a special distribution at or near year-end of such excess amount as may be required. If the
Trust&#8217;s total monthly distributions in any year exceed the amount of its net investment income and net capital gain for the
year, any such excess would be characterized as a return of capital for federal income tax purposes. A return of capital is treated
as a non-dividend distribution for tax purposes and is not subject to current tax. A return of capital reduces a Shareholder&#8217;s
tax cost basis in Trust shares. Under the 1940 Act, for any distribution that includes amounts from sources other than net income,
the Trust is required to provide Common Shareholders a written statement regarding the components of such distribution. Such a
statement will be provided at the time of any distribution believed to include any such amounts.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Common Shareholders may automatically reinvest some or all of
their distributions in additional Common Shares pursuant to the Trust&#8217;s dividend reinvestment plan. See &#8220;Dividend reinvestment

<P STYLE="font: bold 12pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Federal Income Tax Matters</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The discussions below and certain disclosure in the SAI provide
general tax information related to an investment in the Common Shares. Because tax laws are complex and often change, you should
consult your tax adviser about the tax consequences of an investment in the Trust. Unless otherwise noted, the following tax discussion
assumes that you are a U.S. person that is not subject to special rules under the Internal Revenue Code of 1986, as amended (the
&#8220;Code&#8221;), and that you hold the Common Shares as a capital asset (generally, property held for investment).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust has elected to be treated and intends to qualify each
year as a regulated investment company (&#8220;RIC&#8221;) under Subchapter M of the Code. In order to qualify as a RIC, the Trust
must satisfy certain requirements regarding the sources of its income, the diversification of its assets and the distribution of
its income. As a RIC, the Trust is not expected to be subject to U.S. federal income tax to the extent that it distributes its
investment company taxable income and net recognized capital gains.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust currently intends to invest a sufficient portion
of its assets in tax-exempt municipal obligations so that it will be permitted to pay &#8220;exempt-interest dividends&#8221; (as
defined under applicable federal income tax law). Each distribution of exempt-interest dividends, whether paid in cash or reinvested
in additional Common Shares, ordinarily will constitute income exempt from regular federal income tax under current federal tax
law, but it may be subject to state and local taxes. Interest on certain municipal obligations, such as certain private activity
bonds, however, is included as an item of tax preference in determining the amount of a taxpayer&#8217;s alternative minimum taxable
income. To the extent that the Trust receives income from such municipal obligations, a portion of the dividends paid by the Trust,
although exempt from regular federal income tax, will be taxable to Common Shareholders to the extent that their tax liability
is determined under the alternative minimum tax (&#8220;AMT&#8221;). Furthermore, exempt-interest dividends are included in determining
what portion, if any, of a person&#8217;s social security and railroad retirement benefits will be includible in gross income subject
to regular federal income tax. The Trust will annually provide a report indicating the percentage of the Trust&#8217;s income attributable
to municipal obligations subject to the AMT.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In addition to exempt-interest dividends, the Trust also
may distribute to its Common Shareholders amounts that are treated as long-term capital gain or ordinary income (which may include
short-term capital gains). These distributions are generally subject to federal, state and local taxation, depending on a shareholder&#8217;s
situation. Taxable distributions are taxable whether or not such distributions are paid in cash or in additional shares of the
Trust. Distributions by the Trust of its net capital gain (the excess of net long-term capital gain over net short-term capital
loss designated as capital gains dividends) are generally taxable at rates applicable to long-term capital gains regardless of
how long a Common Shareholder has held his or her Common Shares. The Trust does not currently expect that any part of its distributions
to Common Shareholders from its investments will qualify for the dividends-received deduction available to corporate shareholders
or as &#8220;qualified dividend income&#8221; to noncorporate shareholders.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">As a RIC, the Trust will not be subject to U.S. federal income
tax in any taxable year provided that it meets certain distribution requirements. If the Trust retains any net capital gain or
investment company taxable income, it will be subject to tax at regular corporate rates on the amount retained. If the Trust retains
any net capital gain, it may report the retained amount as undistributed capital gains in a timely notice to its Common Shareholders
who, (i) will be required to include in income for U.S. federal income tax purposes, as long-term capital gain, their share of
such undistributed amount; (ii) will be entitled to credit their proportionate shares of the tax paid by the Trust on such undistributed
amount against their U.S. federal income tax liabilities, if any; and (iii) will be entitled to claim refunds to the extent the
credit exceeds such liabilities. The Trust is not required to, and there can be no assurance that the Trust will, make this designation
if it retains all or a portion of its net taxable gain in a taxable year. For U.S. federal income tax purposes, the tax basis of
Common Shares owned by a Common Shareholder of the Trust will be increased by an amount equal to the difference between the amount
of undistributed capital gains included in the shareholder&#8217;s gross income and the tax deemed paid by the Common Shareholder
under clauses (ii) and (iii) of the preceding sentence.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Internal Revenue Service (&#8220;IRS&#8221;) currently requires
that a RIC that has two or more classes of stock allocate to each such class proportionate amounts of each type of its income (such
as exempt interest, ordinary income and capital gains). Accordingly, if the Trust issues preferred shares, it will designate dividends
made with respect to Common Shares and preferred shares as consisting of particular types of income (e.g., exempt interest, net
capital gain and ordinary income) in accordance with the proportionate share of each class in the total dividends paid by the Trust
during the year.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Investors who purchase shares at a time when the Trust's net
asset value reflects gains that are either unrealized or realized but undistributed will pay the full price for the shares and
then may receive some portion of the purchase price back as a taxable distribution.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Dividends and other taxable distributions declared by the Trust
in October, November or December to Common Shareholders of record on a specified date in such month and paid during the following
January will be treated as having been received by Common Shareholders in the year the distributions were declared.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Each Common Shareholder will receive an annual statement summarizing
the source and tax status of all distributions (including net capital gains credited to the Common Shareholder but retained by
the Trust) after the close of the Trust&#8217;s taxable year.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The redemption, sale or exchange of Common Shares normally
will result in capital gain or loss to Common Shareholders. Generally a shareholder&#8217;s gain or loss will be long-term capital
gain or loss if the Common Shares have been held for more than one year, and short-term capital gain or loss if the shares are
held for one year or less. Any loss on the sale of shares that have been held for six months or less will be disallowed to the
extent of any distribution of exempt-interest dividends received with respect to such shares, unless the shares are of a RIC that
declares exempt-interest dividends on a daily basis in an amount equal to at least 90% of its net tax-exempt interest and distributes
such dividends on a monthly or more frequent basis. If a shareholder sells or otherwise disposes of shares before holding them
for more than six months, any loss on the sale or disposition will be treated as a long-term capital loss to the extent of any
net capital gain dividends received by the shareholder on such shares. Any loss realized on a sale or exchange of shares of the
Trust will be disallowed to the extent those shares of the Trust are replaced by other substantially identical shares of the Trust
or other substantially identical stock or securities (including through reinvestment of dividends) within a period of 61 days beginning
30 days before and ending 30 days after the date of disposition of the original shares. In that event, the basis of the replacement
shares of the Trust will be adjusted to reflect the disallowed loss.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Any interest on indebtedness incurred or continued to purchase
or carry the Trust&#8217;s shares on which exempt-interest dividends are paid is not deductible for U.S. federal income tax purposes
in proportion to the percentage that the Trust&#8217;s distribution of exempt-interest dividends bears to all of the Trust&#8217;s
distributions, excluding capital gain dividends. Under certain applicable rules, the purchase or ownership of shares may be considered
to have been made with borrowed funds even though such funds are not directly used for the purchase or ownership of the shares.
In addition, if you receive Social Security or certain railroad retirement benefits, you may be subject to U.S. federal income
tax on a portion of such benefits as a result of receiving investment income, including exempt-interest dividends and other distributions
paid by the Trust.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">If the Trust invests in certain pay-in-kind securities,
zero coupon securities, deferred interest securities or, in general, any other securities with original issue discount (or
with market discount if the Trust elects to include market discount in income currently), the Trust must accrue income on
such investments for each taxable year, which generally will be prior to the receipt of the corresponding cash payments.
However, the Trust must distribute to Common Shareholders, at least annually, all or substantially all of its investment
company taxable income (determined without regard to the deduction for dividends paid) and net tax-exempt income, in each
case including such accrued income, to qualify as a RIC and to avoid federal income and excise taxes. Therefore, the Trust
may have to dispose of its portfolio investments under disadvantageous circumstances to generate cash, or may have to
leverage itself by borrowing the cash, to satisfy these distribution requirements.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The net investment income of certain U.S. individuals, estates
and trusts is subject to a 3.8% Medicare contribution tax. For individuals, the tax is on the lesser of the &#8220;net investment
income&#8221; and the excess of modified adjusted gross income over $200,000 (or $250,000 if married filing jointly). Net investment
income includes, among other things, interest, dividends (other than exempt-interest dividends), and gross income and capital gains
derived from passive activities and trading in securities or commodities. Net investment income is reduced by deductions &#8220;properly
allocable&#8221; to this income.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may be required to &#8220;backup&#8221; withhold,
for U.S. federal income tax purposes, a certain portion of all taxable distributions payable to Common Shareholders who fail to
provide the Trust with their correct taxpayer identification number or to make required certifications, or if the Common Shareholders
have been notified by the IRS that they are subject to backup withholding. Backup withholding is not an additional tax and any
amounts withheld may be credited against a shareholder&#8217;s U.S. federal income tax liability.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Certain foreign entities including foreign entities acting as
intermediaries may be subject to a 30% withholding tax on ordinary dividend income paid under the Foreign Account Tax Compliance
Act (&#8220;FATCA&#8221;). To avoid withholding, foreign financial institutions subject to FATCA must agree to disclose to the
relevant revenue authorities certain information regarding their direct and indirect U.S. owners and other foreign entities must
certify certain information regarding their direct and indirect U.S. owners to the Trust. In addition, the IRS and the Department
of Treasury have issued proposed regulations providing that these withholding rules will not be applicable to the gross proceeds
of share redemptions or capital gain dividends the Trust pays. For more detailed information regarding FATCA withholding and compliance,
please refer to the SAI.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may invest in other securities the U.S. federal income
tax treatment of which is uncertain or subject to recharacterization by the IRS. To the extent the tax treatment of such securities

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Pursuant to the Trust&#8217;s dividend reinvestment plan (the
&#8220;Plan&#8221;), unless a Common Shareholder elects to receive distributions in cash, all distributions will be automatically
reinvested in additional Common Shares.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">American Stock Transfer &amp; Trust Company LLC (the &#8220;Plan
Agent&#8221;) serves as agent for the Common Shareholders in administering the Plan. Common Shareholders who elect not to participate
in the Plan will receive all Trust distributions in cash paid by check mailed directly to the Common Shareholder of record (or
if the Common Shares are held in street or other nominee name, then to the nominee) by the Plan Agent, as disbursing agent. Participation
in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by written notice if received
by the Plan Agent prior to any distribution record date.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Common Shares will be acquired by the Plan Agent or an independent
broker-dealer for the participants&#8217; accounts, depending upon the circumstances described below, either (i) through receipt
of additional previously authorized but unissued Common Shares from the Trust (&#8220;newly issued Common Shares&#8221;) or (ii)
by purchase of outstanding Common Shares on the open market (&#8220;open-market purchases&#8221;) on the NYSE or elsewhere. If
on the payment date for the distribution, the NAV per Common Share is equal to or less than the market price per Common Share plus
estimated brokerage commissions (such condition being referred to herein as &#8220;market premium&#8221;), the Plan Agent will
invest the distribution amount in newly issued Common Shares on behalf of the participants. The number of newly issued Common Shares
to be credited to each participant&#8217;s account will be determined by dividing the dollar amount of the distribution by the
NAV per Common Share on the date the Common Shares are issued, provided that the maximum discount from the then current market
price per Common Share on the date of issuance may not exceed 5%. If on the distribution payment date the NAV per Common Share
is greater than the market value plus estimated brokerage commissions (such condition being referred to herein as &#8220;market
discount&#8221;), the Plan Agent will invest the distribution amount in Common Shares acquired on behalf of the participants in
open-market purchases.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In the event of a market discount on the distribution payment
date, the Plan Agent will have up to 30 days after the distribution payment date to invest the distribution amount in Common Shares
acquired in open-market purchases. If, before the Plan Agent has completed its open-market purchases, the market price of a Common
Share exceeds the NAV per Common Share, the average per Common Share purchase price paid by the Plan Agent may exceed the NAV of
the Common Shares, resulting in the acquisition of fewer Common Shares than if the distribution had been paid in newly issued Common
Shares on the distribution payment date. Therefore, the Plan provides that if the Plan Agent is unable to invest the full distribution
amount in open-market purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Agent will
cease making open-market purchases and will invest the uninvested portion of the distribution amount in newly issued Common Shares.</P>

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

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">There will be no brokerage charges to Common Shares issued directly

not available to Common Shareholders not participating in the Plan. If the market price (plus commissions) of the Common Shares
is above their NAV, participants in the Plan will receive Common Shares of the Trust purchased at a discount to market price and
having a current value that exceeds the cash distributions they would have otherwise received on their Common Shares. If the market
price (plus commissions) of the Common Shares is below their NAV, Plan participants will receive Common Shares with a NAV that
exceeds the cash distributions they would have otherwise received on their Common Shares. There may, however, be insufficient Common
Shares available in the market at prices below NAV to satisfy the Plan&#8217;s requirements, in which case the Plan Agent will
acquire newly issued Common Shares. Also, since the Trust does not redeem its Common Shares, the price on resale may be more or
less than their NAV.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust is an unincorporated business trust established under
the laws of The Commonwealth of Massachusetts by an Agreement and Declaration of Trust (the &#8220;Declaration of Trust&#8221;).
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 Common Shares. The Trust intends to hold annual meetings of shareholders in
compliance with the requirements of the NYSE.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">COMMON SHARES</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Declaration of Trust permits the Trust to issue an unlimited
number of full and fractional Common Shares. Each Common Share represents an equal proportionate interest in the assets of the
Trust with each other Common Share in the Trust. Holders of Common Shares will be entitled to the payment of dividends when, as
and if declared by the Board. The 1940 Act or the terms of any borrowings or preferred shares may limit the payment of dividends
to the holders of Common Shares. Each whole Common Share shall be entitled to one vote as to matters on which it is entitled to
vote pursuant to the terms of the Declaration of Trust on file with the SEC. Upon liquidation of the 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 Common Shares. The Declaration of Trust provides
that shareholders are not liable for any liabilities of the Trust and permits inclusion of a clause to that effect in every agreement
entered into by the Trust and in coordination with the Trust&#8217;s By-Laws 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 and By-Laws described in the foregoing sentence make the likelihood of such personal liability remote.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">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 Common Shares, unless at the time of such
declaration, (i) all accrued dividends on preferred shares or accrued interest on borrowings have been paid and (ii) the value
of the Trust&#8217;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.
These requirements may include an asset coverage test more stringent than under the 1940 Act. This limitation on the Trust&#8217;s
ability to make distributions on its Common Shares could in certain circumstances impair the ability of the Trust to maintain its
qualification for taxation as a regulated investment company for federal income tax purposes. The Trust intends, however, to the
extent possible to purchase or redeem preferred shares or reduce borrowings from time to time to maintain compliance with such
asset coverage requirements and may pay special dividends to the holders of the preferred shares in certain circumstances in connection
with any such impairment of the Trust&#8217;s status as a regulated investment company. See &#8220;Investment Objectives, Policies
and Risks,&#8221; &#8220;Distributions&#8221; and &#8220;Federal Income Tax Matters.&#8221; Depending on the timing of any such

shares to the holders thereof.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust has no present intention of offering additional Common

offering will not be sold at a price per Common Share below the then current NAV (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&#8217;s outstanding
Common Shares. The Common Shares have no preemptive rights.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Because shares of closed-end management investment companies
frequently trade at a discount to their NAVs, the Board has determined that from time to time it may be in the interest of shareholders
for the Trust to take corrective actions. The Board, in consultation with Eaton Vance, will review at least annually the possibility
of open market repurchases and/or tender offers for the Common Shares and will consider such factors as the market price of the
Common Shares, the NAV of the Common Shares, the liquidity of the assets of the Trust, effect on the Trust&#8217;s expenses, whether
such transactions would impair the Trust&#8217;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&#8217;s ability to consummate such transactions. There are no assurances that the Board will, in fact, decide
to undertake either of these actions or if undertaken, that such actions will result in the Trust&#8217;s Common Shares trading
at a price which is equal to or approximates their NAV. In recognition of the possibility that the Common Shares might trade at
a discount to NAV and that any such discount may not be in the interest of shareholders, the Board, in consultation with Eaton
Vance, from time to time may review possible actions to reduce any such discount.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The Board of Trustees initially approved a share repurchase
program for the Trust on November 11, 2013. Pursuant to the reauthorization of the share repurchase program by the Board of Trustees
in December 2019, the Trust is authorized to repurchase up to 10% of its common shares outstanding as of the last day of the prior
calendar year at market prices when shares are trading at a discount to net asset value. The share repurchase program does not
obligate the Trust to purchase a specific amount of shares. Results of the share repurchase program are disclosed in the Trust&#8217;s
annual and semiannual reports to shareholders.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust has no current intention of issuing any shares other
than the Common Shares. However, the Declaration of Trust authorizes the issuance of an unlimited number of shares of beneficial
interest with preference rights (the &#8220;preferred shares&#8221;) in one or more series, with rights as determined by the Board,
by action of the Board without the approval of the Common Shareholders.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 0">&nbsp;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Under the requirements of the 1940 Act, the Trust must, immediately
after the issuance of any preferred shares, have an &#8220;asset coverage&#8221; of at least 200%. 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 senior securities representing indebtedness of the Trust, if any, plus
the aggregate liquidation preference of the preferred shares. If the Trust seeks a rating for preferred shares, asset coverage
requirements in addition to those set forth in the 1940 Act may be imposed. The liquidation value of any preferred shares would
be expected to equal their aggregate original purchase price plus redemption premium, if any, together with any accrued and unpaid
distributions thereon (on a cumulative basis), whether or not earned or declared. The terms of any preferred shares, including
their distribution rate, voting rights, liquidation preference and redemption provisions, will be determined by the Board (subject
to applicable law and the Trust&#8217;s Declaration of Trust) if and when it authorizes preferred shares. The Trust may issue preferred
shares that provide for the periodic redetermination of the distribution rate at relatively short intervals through an auction
or remarketing procedure, although the terms of such preferred shares may also enable the Trust to lengthen such intervals. At
times, the distribution rate on any preferred shares may exceed the Trust&#8217;s return after expenses on the investment of proceeds
from the preferred shares and the Trust&#8217;s leverage structure, resulting in a lower rate of return to Common Shareholders
than if the Trust were not so structured.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">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 Common Shareholders. 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.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Holders of preferred shares, voting as a class, would be entitled
to elect two of the Trust&#8217;s Trustees if any preferred shares are issued. The holders of both the Common Shares and the preferred
shares (voting together as a single class with each share entitling its holder to one vote) would be entitled to elect the remaining
Trustees of the Trust. Under the 1940 Act, if at any time dividends on the preferred shares are unpaid in an amount equal to two
full years&#8217; dividends thereon, the holders of all outstanding preferred shares, voting as a class, will be allowed to elect
a majority of the Board until all distributions in arrears have been paid or declared and set apart for payment. In addition, if
required by a Rating Agency rating the preferred shares or if the Board determines it to be in the best interests of the Common
Shareholders, issuance of the preferred shares may result in more restrictive provisions than required under the 1940 Act. In this
regard, holders of preferred shares may be entitled to elect a majority of the Board in other circumstances, for example, if one
payment on the preferred shares is in arrears. The differing rights of the holders of preferred and Common Shares with respect
to the election of Trustees do not affect the obligation of all Trustees to take actions they believe to be consistent with the
best interests of the Trust. All such actions must be consistent with (i) the obligations of the Trust with respect to the holders
of preferred shares (which obligations arise primarily from the contractual terms of the preferred shares, as specified in the
Declaration of Trust and By-laws of the Trust) and (ii) the fiduciary duties owed to the Trust, which include the duties of loyalty
and care.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In the event of any future issuance of preferred shares, the
Trust likely would seek a credit rating for such preferred shares from a Rating Agency. In such event, as long as preferred shares
are outstanding, the composition of its portfolio will reflect guidelines established by such Rating Agency. Based on previous
guidelines established by Rating Agencies for the securities of other issuers, the Trust anticipates that the guidelines with respect
to any preferred shares would establish a set of tests for portfolio composition and asset coverage that supplement (and in some
cases are more restrictive than) the applicable requirements under the 1940 Act. Although no assurance can be given as to the nature
or extent of the guidelines that may be imposed in connection with obtaining a rating of any preferred shares, the Trust anticipates
that such guidelines would include asset coverage requirements that are more restrictive than those under the 1940 Act, restrictions
on certain portfolio investments and investment practices and certain mandatory redemption requirements relating to any preferred
shares. No assurance can be given that the guidelines actually imposed with respect to any preferred shares by a Rating Agency
would be more or less restrictive than those described in this Prospectus.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">EFFECTS OF LEVERAGE</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">As discussed above, the Trust currently uses leverage in the
form of residual interest bonds. The Trust will not utilize leverage in excess of 15% of its gross assets. Although the Trust has
no current intention to do so, the Trust is authorized also to utilize leverage through the issuance of preferred shares and/or
borrowings, including the issuance of debt securities. The Trust may borrow for temporary, emergency or other purposes as permitted
by the 1940 Act. In the event that the Trust determines in the future to utilize alternative or additional forms of leverage, there
can be no assurance that such strategy would be successful during any period in which it is employed. Leverage creates risks for
Common Shareholders, including the likelihood of greater volatility of NAV and market price of the Common Shares and the risk that
fluctuations in leverage costs may affect the income and return to Common Shareholders. To the extent the amounts</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">available for distribution derived from securities purchased
with proceeds received from leverage exceed the cost of leverage, the Trust&#8217;s distributions would be greater than if leverage
had not been used. Conversely, if the amounts available for distribution derived from securities purchased with such proceeds are
not sufficient to cover the cost of leverage, distributions to Common Shareholders would be less than if leverage had not been
used. In the latter case, Eaton Vance, in its best judgment, may nevertheless determine to maintain the Trust&#8217;s leveraged
position if it deems such action to be appropriate. The costs of an offering of preferred shares and/or a borrowing program would
be borne by Common Shareholders and consequently would result in a reduction of the NAV of Common Shares.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In addition, the advisory fee paid to Eaton Vance is calculated
on the basis of the Trust&#8217;s average daily gross assets. &#8220;Gross assets&#8221; of the Trust means total assets of the
Trust, including assets attributable to any form of leverage, minus all accrued expenses incurred in the normal course of operations,
but not excluding any liabilities or obligations attributable to leverage obtained through (i) indebtedness of any type (including,
without limitation, borrowing through a credit facility or the issuance of debt securities), (ii) the issuance of preferred stock
or other similar preference securities, (iii) the reinvestment of collateral received for securities loaned in accordance with
the Trust&#8217;s investment objectives and policies, and/or (iv) any other means; all as determined in accordance with generally
accepted accounting principles. This means that the advisory fees paid by the Trust would be higher if leverage is utilized. In
this regard, holders of preferred shares would not bear the investment advisory fee. Rather, Common Shareholders would bear the
portion of the investment advisory fee attributable to the assets purchased with the proceeds of the preferred shares offering.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0 3pt">CERTAIN PROVISIONS OF THE DECLARATION OF TRUST</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 6pt">Anti-Takeover Provisions in the Declaration of Trust</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">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, and could have the effect of depriving holders of Common Shares 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 is divided into three classes, with the term of
one class expiring at each annual meeting of holders of Common Shares and preferred shares. At each annual meeting, one class of
Trustees is elected to a three-year term. This provision could delay for up to two years the replacement of a majority of the Board.
A Trustee may be removed from office only (i) for cause by a written instrument signed by the remaining Trustees or (ii) by a vote
of the holders of at least two-thirds of the class of shares of the Trust that elected such Trustee and are entitled to vote on
the matter.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">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 (&#8220;Principal Shareholders&#8221;) of a class
of shares and their associates, unless the Board shall by resolution have approved a memorandum of understanding with such holders,
in which case normal voting requirements would be in effect. For purposes of these provisions, a Principal Shareholder refers to
any person who, whether directly or indirectly and whether alone or together with its affiliates and associates, beneficially owns
5% or more of the outstanding shares of any class of beneficial interest of the 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 determined by the Board to
have an aggregate fair market value of less than $1,000,000, aggregating for the purpose of such computation all assets sold, leased
or exchanged in any series of similar transactions within a twelve-month period); or (iv) the sale, lease or exchange to or with
the Trust or any subsidiary thereof, in exchange for securities of the Trust, of any assets of any Principal Shareholder (except
assets determined by the Board to have 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).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Board has determined that provisions with respect to the
Board and the 75% voting requirements described above, which voting requirements are greater than the minimum requirements under
Massachusetts law or the 1940 Act, are in the best interest of holders of Common Shares and preferred shares generally. Reference
should be made to the Declaration of Trust on file with the SEC for the full text of these provisions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may be converted to an open-end investment company
at any time if approved by the lesser of (i) two-thirds or more of the Trust&#8217;s then outstanding Common Shares and preferred
shares, each voting separately as a class, or (ii) more than 50% of the then outstanding Common Shares and preferred shares, 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 Common Shareholders&#8217; meeting at which such conversion
was approved and would also require at least 30 days&#8217; prior notice to all Common Shareholders. Conversion of the Trust to
an open-end management investment company also would require the redemption of any outstanding preferred shares could require the
repayment of borrowings. The Board believes that the closed-end structure is desirable, given the Trust&#8217;s investment objectives
and policies. Investors should assume, therefore, that it is unlikely that the Board would vote to convert the Trust to an open-end
management investment company.</P>

The following is a description of the various investment practices that may be engaged in, whether as a primary or secondary strategy,

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">OTHER INVESTMENTS</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Municipal
Obligations. </B></FONT>Municipal obligations include debt obligations issued to obtain funds for various public purposes, including
the construction of a wide range of public facilities, refunding of outstanding obligations and obtaining funds for general operating
expenses and loans to other public institutions and facilities. Certain types of bonds are issued by or on behalf of public authorities
to finance various privately owned or operated facilities, including certain facilities for the local furnishing of electric energy
or gas, sewage facilities, solid waste disposal facilities and other specialized facilities. Municipal obligations include bonds
as well as tax-exempt commercial paper, project notes and municipal notes such as tax, revenue and bond anticipation notes of short
maturity, generally less than three years. While most municipal bonds pay a fixed rate of interest semiannually in cash, there
are exceptions. Some bonds pay no periodic cash interest, but rather make a single payment at maturity representing both principal
and interest. Some bonds may pay interest at a variable or floating rate. Bonds may be issued or subsequently offered with interest
coupons materially greater or less than those then prevailing, with price adjustments reflecting such deviation. Municipal obligations
also include trust certificates representing interests in municipal securities held by a trustee. The trust certificates may evidence
ownership of future interest payments, principal payments or both on the underlying securities.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In general, there are three categories of municipal obligations,
the interest on which is exempt from federal income tax and is not a tax preference item for purposes of the alternative minimum
tax (&#8220;AMT&#8221;): (i) certain &#8220;public purpose&#8221; obligations (whenever issued), which include obligations issued
directly by state and local governments or their agencies to fulfill essential governmental functions; (ii) certain obligations
issued before August 8, 1986 for the benefit of non-governmental persons or entities; and (iii) certain &#8220;private activity
bonds&#8221; issued after August 7, 1986, which include &#8220;qualified Section 501(c)(3) bonds&#8221; or refundings of certain
obligations included in the second category. Opinions relating to the validity of municipal bonds, exclusion of municipal bond
interest from an investor&#8217;s gross income for federal income tax purposes and, where applicable, state and local income tax,
are rendered by bond counsel to the issuing authorities at the time of issuance.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Interest on certain &#8220;private activity bonds&#8221; (not
including the bonds described in clause (iii) of the previous paragraph) issued after August 7, 1986 is exempt from regular federal
income tax, but such interest (including a distribution by the Trust derived from such interest) is treated as a tax preference
item that could subject the recipient to or increase the recipient&#8217;s liability for the AMT.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The two principal classifications of municipal bonds are &#8220;general
obligation&#8221; and &#8220;revenue&#8221; bonds. Issuers of general obligation bonds include states, counties, cities, towns
and regional districts. The proceeds of these obligations are used to fund a wide range of public projects, including the construction
or improvement of schools, highways and roads, water and sewer systems and a variety of other public purposes. The basic security
of general obligation bonds is the issuer&#8217;s pledge of its faith, credit, and taxing power for the payment of principal and
interest. The taxes that can be levied for the payment of debt service may be limited or unlimited as to rate and amount.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Typically, the only security for a limited obligation or revenue
bond is the net revenue derived from a particular facility or class of facilities financed thereby or, in some cases, from the
proceeds of a special tax or other special revenues. Revenue bonds have been issued to fund a wide variety of revenue-producing
public capital projects including: electric, gas, water and sewer systems; highways, bridges and tunnels; port and airport facilities;
colleges and universities; hospitals; and convention, recreational, tribal gaming and housing facilities. Although the security
behind these bonds varies widely, many lower rated bonds provide additional security in the form of a debt service reserve fund
that may also be used to make principal and interest payments on the issuer's obligations. In addition, some revenue obligations
(as well as general obligations) are insured by a bond insurance company or backed by a letter of credit issued by a banking institution.
Revenue bonds also include, for example, pollution control, health care and housing bonds, which, although nominally issued by
municipal authorities, are generally not secured by the taxing power of the municipality but by the revenues of the authority derived
from payments by the private entity that owns or operates the facility financed with the proceeds of the bonds. Obligations of
housing finance authorities have a wide range of security features, including reserve funds and insured or subsidized mortgages,
as well as the net revenues from housing or other public projects. Many of these bonds do not generally constitute the pledge of
the credit of the issuer of such bonds. The credit quality of such revenue bonds is usually directly related to the credit standing
of the user of the facility being financed or of an institution which provides a guarantee, letter of credit or other
credit enhancement for the bond issue. The Trust may on occasion acquire revenue bonds that carry warrants or similar rights covering
equity securities. Such warrants or rights may be held indefinitely, but if exercised, the Trust anticipates that it would, under
normal circumstances, dispose of any equity securities so acquired within a reasonable period of time. Investing in revenue bonds
may involve (without limitation) the following risks.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"></P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Hospital bond ratings are often based on feasibility studies
that contain projections of expenses, revenues and occupancy levels. A hospital&#8217;s income available to service its debt may
be influenced by demand for hospital services, management capabilities, the service area economy, efforts by insurers and government
agencies to limit rates and expenses, competition, availability and expense of malpractice insurance, and Medicaid and Medicare
funding.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Education-related bonds are comprised of two types: (i) those
issued to finance projects for public and private colleges and universities, charter schools and private schools, and (ii) those
representing pooled interests in student loans. Bonds issued to supply educational institutions with funding are subject to many
risks, including the risks of unanticipated revenue decline, primarily the result of decreasing student enrollment, decreasing
state and federal funding, or changes in general economic conditions. Additionally, higher than anticipated costs associated with
salaries, utilities, insurance or other general expenses could impair the ability of a borrower to make annual debt service payments.
Student loan revenue bonds are generally offered by state (or sub-state) authorities or commissions and are backed by pools of
student loans. Underlying student loans may be guaranteed by state guarantee agencies and may be subject to reimbursement by the
United States Department of Education through its guaranteed student loan program. Others may be private, uninsured loans made
to parents or students that may be supported by reserves or other forms of credit enhancement. Cash flows supporting student loan
revenue bonds are impacted by numerous factors, including the rate of student loan defaults, seasoning of the loan portfolio, and
student repayment deferral periods of forbearance. Other risks associated with student loan revenue bonds include potential changes
in federal legislation regarding student loan revenue bonds, state guarantee agency reimbursement and continued federal interest
and other program subsidies currently in effect.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Transportation debt may be issued to finance the construction
of airports, toll roads, highways, or other transit facilities. Airport bonds are dependent on the economic conditions of the airport&#8217;s
service area and may be affected by the business strategies and fortunes of specific airlines. They may also be subject to competition
from other airports and modes of transportation. Air traffic generally follows broader economic trends and is also affected by
the price and availability of fuel. Toll road bonds are also affected by the cost and availability of fuel as well as toll levels,
the presence of competing roads and the general economic health of an area. Fuel costs, transportation taxes and fees, and availability
of fuel also affect other transportation-related securities, as do the presence of alternate forms of transportation, such as public
transportation.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Industrial development bonds (&#8220;IDBs&#8221;) are normally
secured only by the revenues from the project and not by state or local government tax payments, they are subject to a wide variety
of risks, many of which relate to the nature of the specific project. Generally, IDBs are sensitive to the risk of a slowdown in
the economy.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Electric utilities face problems in financing large construction
programs in an inflationary period, cost increases and delay occasioned by safety and environmental considerations (particularly
with respect to nuclear facilities), difficulty in obtaining fuel at reasonable prices, and in achieving timely and adequate rate
relief from regulatory commissions, effects of energy conservation and limitations on the capacity of the capital market to absorb
utility debt.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Water and sewer revenue bonds are generally secured by the fees
charged to each user of the service. The issuers of water and sewer revenue bonds generally enjoy a monopoly status and latitude
in their ability to raise rates. However, lack of water supply due to insufficient rain, run-off, or snow pack can be a concern
and has led to past defaults. Further, public resistance to rate increases, declining numbers of customers in a particular locale,
costly environmental litigation, and federal environmental mandates are challenges faced by issuers of water and sewer bonds.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Standard tobacco bonds are secured by a single source of revenue,
installment payments made by tobacco companies stemming from the settlement of lawsuits brought against them by various states
(the &#8220;Master Settlement Agreement&#8221;). Appropriation backed tobacco bonds are supported by the same Master Settlement
Agreement payments as standard tobacco bonds, but are also subject to a state&#8217;s pledge that the governor will request an
appropriation of funds in its annual budget for debt service if Master Settlement Agreement revenues are insufficient. These payments
are not generally fixed but rather are tied to the volume of the company&#8217;s U.S. sales of cigarettes. Tobacco bonds are subject
to several risks, including the risk that cigarette consumption declines or that a tobacco company defaults on its obligation to
make payments to the state. Escrowed tobacco bonds no longer rely on Master Settlement Agreement revenue as security, and are backed
by a variety of government securities.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Certain tax-exempt bonds issued by Native American tribes may
be subject to the risk that a taxing authority would determine that the income from such bonds is not eligible for tax-exempt status.
In the event of any final adverse ruling to this effect, holders of such bonds may be subject to penalties.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The obligations of any person or entity to pay the principal
of and interest on a municipal obligation are subject to the provisions of bankruptcy, insolvency and other laws affecting the
rights and remedies of creditors, such as the Federal Bankruptcy Act, and laws, if any, that may be enacted by Congress or state
legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of
such obligations. Certain bond structures may be subject to the risk that a taxing authority may issue an adverse ruling regarding
tax-exempt status. There is also the possibility that as a result of adverse economic conditions (including unforeseen financial
events, natural disasters and other conditions that may affect an issuer&#8217;s ability to pay its obligations), litigation or
other conditions, the power or ability of any person or entity to pay when due principal of and interest on a municipal obligation
may be materially affected or interest and principal previously paid may be required to be refunded. There have been instances
of defaults and bankruptcies involving municipal obligations that were not foreseen by the financial and investment communities.
The Trust will take whatever action it considers appropriate in the event of anticipated financial difficulties, default or bankruptcy
of either the issuer of any municipal obligation or of the underlying source of funds for debt service. Such action may include:
(i) retaining the services of various persons or firms (including affiliates of the investment adviser) to evaluate or protect
any real estate, facilities or other assets securing any such obligation or acquired by the Trust as a result of any such event;
(ii) managing (or engaging other persons to manage) or otherwise dealing with any real estate, facilities or other assets so acquired;
and (iii) taking such other actions as the adviser (including, but not limited to, payment of operating or similar expenses of
the underlying project) may deem appropriate to reduce the likelihood or severity of loss on the fund&#8217;s investment.&nbsp;
The Trust will incur additional expenditures in taking protective action with respect to portfolio obligations in (or anticipated
to be in) default and assets securing such obligations.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Historically, municipal bankruptcies have been rare and certain
provisions of the U.S. Bankruptcy Code governing such bankruptcy are unclear. Further, the application of state law to municipal
obligation issuers could produce varying results among the states or among municipal obligation issuers within a state. These uncertainties
could have a significant impact on the prices of the municipal obligations in which the Trust invests. There could be economic,
business or political developments or court decisions that adversely affect all municipal obligations in the same sector. Developments
such as changes in healthcare regulations, environmental considerations related to construction, construction cost increases and
labor problems, failure of healthcare facilities to maintain adequate occupancy levels, and inflation can affect municipal obligations
in the same sector. As the similarity in issuers of municipal obligations held by the Trust increases, the potential for fluctuations
in the Trust&#8217;s share price also may increase.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The secondary market for some municipal obligations issued within
a state (including issues that are privately placed with the Trust) is less liquid than that for taxable debt obligations or other
more widely traded municipal obligations. No established resale market exists for certain of the municipal obligations in which
the Trust may invest. The market for obligations rated below investment grade is also likely to be less liquid than the market
for higher rated obligations. As a result, the Trust may be unable to dispose of these municipal obligations at times when it would
otherwise wish to do so at the prices at which they are valued.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Municipal obligations that are rated below investment grade but
that, subsequent to the assignment of such rating, are backed by escrow accounts containing U.S. Government obligations may be
determined by the investment adviser to be of investment grade quality for purposes of the Trust&#8217;s investment policies. In
the case of a defaulted obligation, the Trust may incur additional expense seeking recovery of its investment. Defaulted obligations
are denoted in the &#8220;Portfolio of Investments&#8221; in the &#8220;Financial Statements&#8221; included in the Trust&#8217;s
reports to shareholders.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The yields on municipal obligations depend on a variety of factors,
including purposes of the issue and source of funds for repayment, general money market conditions, general conditions of the municipal
bond market, size of a particular offering, maturity of the obligation and rating of the issue. The ratings of Moody&#8217;s, S&amp;P
and Fitch represent their opinions as to the quality of the municipal obligations which they undertake to rate, and in the case
of insurers, other factors including the claims-paying ability of such insurer. It should be emphasized, however, that ratings
are based on judgment and are not absolute standards of quality. Consequently, municipal obligations with the same maturity, coupon
and rating may have different yields while obligations of the same maturity and coupon with different ratings may have the same
yield. In addition, the market price of such obligations will normally fluctuate with changes in interest rates, and therefore
the net asset value of the Trust will be affected by such changes.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>State
Specific Investments.</B></FONT> If the Trust invests 25% or more of its gross assets in any one state (or U.S. territory), the
Trust may be more susceptible to adverse economic, political or regulatory occurrences affecting a particular state (or U.S. territory).
Municipal obligations of issuers located in a single state may be adversely affected by economic developments (including insolvency
of an issuer) and by legislation and other governmental activities in that state. There could be economic, business or political
developments or court decisions that adversely affect all municipal obligations in the same sector. In particular, investments
in revenue bonds might involve (without limitation) the following risks. For purposes of this policy, the Trust&#8217;s investments
in pre-refunded municipal obligations that are fully backed as to payment of principal and interest by a pledge to an independent
escrow agent of U.S. Government securities shall not count as obligations of an issuer located in a particular state. The Commonwealth
of Puerto Rico and its related issuers continue to experience financial difficulties and rating agency downgrades,
and numerous issuers have entered Title III of the Puerto Rico Oversite, Management and Economic Stability Act, which is similar
to bankruptcy protection, through which the Commonwealth of Puerto Rico can restructure its debt. Puerto Rico&#8217;s short-term
financial difficulties continue to be further impacted by the 2017 hurricane.</P>

Obligations.</B></FONT> The Trust may purchase municipal obligations insured as to their scheduled payment of principal and interest
or municipal obligations that are additionally secured by bank credit agreements or escrow accounts.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The credit quality of companies that provide such credit enhancements
will affect the value of those securities. Although the insurance feature may reduce certain financial risks, the premiums for
insurance and the higher market price sometimes paid for insured obligations may reduce the Trust&#8217;s current yield. See Appendix
A for a description of the claims-paying ability ratings of S&amp;P and Moody&#8217;s. The insurance does not guarantee the market
value of the insured obligation or the NAV of the Trust&#8217;s shares. To the extent that securities held by the Trust are insured
as to principal and interest payments by insurers whose claims-paying ability rating is downgraded by Moody&#8217;s, S&amp;P or
Fitch, the value of such securities may be affected.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Credit
Quality. </B></FONT>While municipal obligations rated investment grade or below and comparable unrated municipal obligations may
have some quality and protective characteristics, these characteristics can be expected to be offset or outweighed by uncertainties
or major risk exposures to adverse conditions. Lower rated and comparable unrated municipal obligations are subject to the risk
of an issuer&#8217;s inability to meet principal and interest payments on the obligations (credit risk) and may also be subject
to greater price volatility due to such factors as interest rate sensitivity, market perception of the creditworthiness of the
issuer and general market liquidity (market risk). Lower rated or unrated municipal obligations are also more likely to react to
real or perceived developments affecting market and credit risk than are more highly rated obligations, which react primarily to
movements in the general level of interest rates.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Municipal obligations held by the Trust which are rated below
investment grade but which, subsequent to the assignment of such rating, are backed by escrow accounts containing U.S. Government
obligations may be determined by the investment adviser to be of investment grade quality for purposes of the Trust&#8217;s investment
policies. The Trust may retain in its portfolio an obligation whose rating drops after its acquisition, including defaulted obligations,
if such retention is considered desirable by the investment adviser; provided, however, that holdings of obligations rated below
Baa or BBB will be less than 30% of the Trust&#8217;s investments in municipal obligations and holdings rated below B- by Standard
&amp; Poor&#8217;s or Fitch or B3 by Moody&#8217;s will be less than 5% of its municipal obligations investments, each at the time
of purchase. In the case of a defaulted obligation, the Trust may incur additional expense seeking recovery of its investment.
See &#8220;Portfolio of Investments&#8221; in the &#8220;Financial Statements&#8221; incorporated by reference into this SAI with
respect to any defaulted obligations held by the Trust.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">When the Trust invests in lower rated or unrated municipal obligations,
the achievement of the Trust&#8217;s goals is more dependent on the investment adviser&#8217;s ability than would be the case if
the Trust were investing in municipal obligations in the higher rating categories. In evaluating the credit quality of a particular
issue, whether rated or unrated, the investment adviser may take into consideration, among other things, the financial resources
of the issuer (or, as appropriate, of the underlying source of funds for debt service), its sensitivity to economic conditions
and trends, any operating history of and the community support for the facility financed by the issue, the ability of the issuer&#8217;s
management and regulatory matters. The investment adviser may also purchase structured derivative products with greater or lesser
credit risk than the underlying bonds. Such bonds may be rated investment grade, as well as below investment grade. For a description
of municipal bond ratings, see Appendix A.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Municipal
Leases. </B></FONT>The Trust may invest in municipal lease obligations and certificates of participation, which arrangements frequently
involve special risks. A municipal lease obligation is a bond that is secured by lease payments made by the party, typically a
state or municipality, leasing the facilities (e.g., schools or office buildings) that were financed by the bond. Such lease payments
may be subject to annual appropriation or may be made only from revenues associated with the facility financed. In other cases,
the leasing state or municipality is obligated to appropriate funds from its general tax revenues to make lease payments as long
as it utilizes the leased property. A certificate of participation (also referred to as a &#8220;participation&#8221;) in a municipal
lease is an instrument evidencing a pro rata share in a specific pledged revenue stream, usually lease payments by the issuer that
are typically subject to annual appropriation. The certificate generally entitles the holder to receive a share, or participation,
in the payments from a particular project. Municipal lease obligations and participations are subject to the risk that the legislative
body will not make the necessary appropriation and the issuer will not otherwise be willing or able to meet its obligation.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">MLOs and participations therein represent a type of financing
that may not have the depth of marketability associated with more conventional securities and, as such, they may be less liquid
than conventional securities. In the event the Trust acquires an unrated municipal lease obligation, the investment adviser will
be responsible for determining the credit quality of such obligation on an ongoing basis, including an assessment of the likelihood
that the lease may or may not be cancelled. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The ability of issuers of MLOs to make timely lease payments
may be adversely impacted in general economic downturns and as relative governmental cost burdens are allocated and reallocated
among federal, state and local governmental units. Such non-payment would result in a reduction of income from and value of the
obligation. Issuers of MLOs might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, holders
of MLOs could experience delays and limitations with respect to the collection of principal and interest on such MLOs and may not,
in all circumstances, be able to collect all principal and interest to which it is entitled. To enforce its rights in the event
of a default in lease payments, the Trust might take possession of and manage the assets securing the issuer&#8217;s obligations
on such securities or otherwise incur costs to protect its rights, which may increase the Trust&#8217;s operating expenses and
adversely affect the net asset value of the Trust. When the lease contains a non-appropriation clause, however, the failure to
pay would not be a default and the Trust would not have the right to take possession of the assets. Any income derived from the
Trust&#8217;s ownership or operation of such assets may not be tax-exempt.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Zero
Coupon and Deep Discount Bonds and Payment-in-Kind (&#8220;PIK&#8221;) Securities.</B></FONT> Zero coupon bonds are debt obligations
that do not require the periodic payment of interest and are issued at a significant discount from face value. The discount approximates
the total amount of interest the bonds will accrue and compound over the period until maturity at a rate of interest reflecting
the market rate of the security at the time of purchase. The effect of owning debt obligations that do not make current interest
payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during
the life of the debt obligation. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to
invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder&#8217;s
ability to reinvest at higher rates in the future. Deep discount bonds also are issued at a discount from face value, but may make
periodic interest payments at a below market interest rate.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Payment-in-kind securities (&#8220;PIKs&#8221;) are debt obligations
that pay &#8220;interest&#8221; in the form of other debt obligations, instead of in cash. Each of these instruments is normally
issued and traded at a deep discount from face value. Zero-coupon bonds, step-ups and PIKs allow an issuer to avoid or delay the
need to generate cash to meet current interest payments and, as a result, may involve greater credit risk than bonds that pay interest
currently or in cash. The Trust would be required to distribute the income on these instruments as it accrues, even though the
Trust will not receive the income on a current basis or in cash. Thus, the Trust may have to sell other investments, including
when it may not be advisable to do so, to make income distributions to its shareholders. PIKs and other obligations that do not
pay regular income distributions may experience greater volatility in response to interest rate changes and issuer developments.
PIKs generally carry higher interest rates compared to obligations that make cash payments of interest to reflect their payment
deferral and increased credit risk. Even if accounting conditions are met for accruing income payable at a future date under a
PIK, the issuer could still default when the collection date occurs at the maturity of or payment date for the PIK. PIKs may be
difficult to value accurately because they involve ongoing judgments as to the collectability of the deferred payments and the
value of any associated collateral. If the issuer of a PIK defaults the Trust may lose its entire investment. PIK interest has
the effect of generating investment income and increasing the incentive fees, if any, payable at a compounding rate. Generally,
the deferral of PIK interest increases the loan to value ratio.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Bonds and preferred stocks that make &#8220;in-kind&#8221;
payments and other securities that do not pay regular income distributions may experience greater volatility in response to interest
rate changes and issuer developments. PIK securities generally involve significantly greater credit risk than coupon loans because
the Trust receives no cash payments until the maturity date or a specified cash payment date. Even if accounting conditions are
met for accruing income payable at a future date under a PIK bond, the issuer could still default when the collection date occurs
at the maturity of or payment date for the PIK bond. PIK bonds may be difficult to value accurately because they involve ongoing
judgments as to the collectability of the deferred payments and the value of any associated collateral. If the issuer of a PIK
security defaults, the Trust may lose its entire investment.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust is required to accrue income from zero coupon and
deep discount bonds and PIK securities on a current basis, even though it does not receive that income currently in cash, and the
Trust is required to distribute that income for each taxable year. Such distributions could reduce the Trust&#8217;s cash position
and require it to sell securities and incur a gain or loss at a time it may not otherwise want to in order to provide the cash
necessary for these distributions. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>When-Issued,
Delayed Delivery and Forward Commitment Transactions.</B></FONT> Securities may be purchased on a &#8220;forward commitment,&#8221;
&#8220;when-issued&#8221; or &#8220;delayed delivery&#8221; basis (meaning securities are purchased or sold with payment and delivery
taking place in the future) in order to secure what is considered to be an advantageous price and yield at the time of entering
into the transaction. When the Trust agrees to purchase such securities, it assumes the risk of any decline in value of the security
from the date of the agreement to purchase. The Trust does not earn interest on the securities it has committed to purchase until
they are paid for and delivered on the settlement date.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">From the time of entering into the transaction until delivery
and payment is made at a later date, the securities that are the subject of the transaction are subject to market fluctuations.
In forward commitment, when-issued or delayed delivery transactions, if the seller or buyer, as the case may be, fails to consummate
the transaction the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous. However,
no payment or delivery is made until payment is received or delivery is made from the other party to the transaction.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust will make commitments to purchase when-issued securities
only with the intention of actually acquiring the securities, but may sell such securities before the settlement date if it is
deemed advisable as a matter of investment strategy. The payment obligation and the interest rate that will be received on the
securities are fixed at the time the Trust enters into the purchase commitment. When the Trust commits to purchase a security on
a when-issued basis it records the transaction and reflects the value of the security in determining its net asset value. Securities
purchased on a when-issued basis and the securities held by the Trust are subject to changes in value based upon the perception
of the creditworthiness of the issuer and changes in the level of interest rates (i.e., appreciation when interest rates decline
and depreciation when interest rates rise). Therefore, to the extent that the Trust remains substantially fully invested at the
same time that it has purchased securities on a when-issued basis, there will be greater fluctuations in the Trust&#8217;s net
asset value than if it solely set aside cash to pay for when-issued securities.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Credit
Derivatives.</B></FONT> The Trust may invest in credit default swaps, total return swaps or credit options for hedging and other
risk management purposes. In a credit default swap, the buyer of credit protection (or seller of credit risk) agrees to pay the
counterparty a fixed, periodic premium for a specified term. In return, the counterparty agrees to pay a contingent payment to
the buyer in the event of an agreed upon credit occurrence with respect to a particular reference instrument. In a total return
swap, the buyer receives a periodic return equal to the total economic return of a specified security, securities or index, for
a specified period of time. In return, the buyer pays the counterparty a variable stream of payments, typically based upon short
term interest rates, possibly plus or minus an agreed upon spread. Credit options are options whereby the purchaser has the right,
but not the obligation, to enter into a transaction involving either an asset with inherent credit risk or a credit derivative,
at terms specified at the initiation of the option. Transactions in derivative instruments involve a risk of loss or depreciation
due to: unanticipated adverse changes in securities prices, interest rates, indices, the other financial instruments&#8217; prices
or currency exchange rates; the inability to close out a position; default by the counterparty; imperfect correlation between a
position and the desired hedge; tax constraints on closing out positions; and portfolio management constraints on securities subject
to such transactions. Derivative instruments may sometimes increase or leverage exposure to a particular market risk, thereby increasing
price volatility. The counterparties to many derivatives transactions are investment banks (or, if recently restructured, formerly
categorized as investment banks), an industry that has recently experienced higher than normal bankruptcies. The risk of counterparty
default increases in the event such counterparties undergo bankruptcy or are otherwise part of an industry affected by increased
bankruptcy activity.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Redemption,
Demand and Put Features and Put Options. </B></FONT> Issuers of municipal obligations reserve the right to call (redeem) the bond.
If an issuer redeems securities held by the Trust during a time of declining interest rates, the Trust may not be able to reinvest
the proceeds in securities providing the same investment return as the securities redeemed. Also, some bonds may have &#8220;put&#8221;
or &#8220;demand&#8221; features that allow early redemption by the bondholder. Longer term fixed-rate bonds may give the holder
a right to request redemption at certain times (often annually after the lapse of an intermediate term). These bonds are more defensive
than conventional long term bonds (protecting to some degree against a rise in interest rates) while providing greater opportunity
than comparable intermediate term bonds, because the Trust may retain the bond if interest rates decline.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Liquidity
and Protective Put Options.</B></FONT> The Trust may enter into a separate agreement with the seller of the security or some other
person granting the Trust the right to put the security to the seller thereof or the other person at an agreed upon price. Such
agreements are subject to the risk of default by the other party, although the Trust intends to limit this type of transaction
to institutions (such as banks or securities dealers) that the Adviser believes present minimal credit risks and would engage in
this type of transaction to facilitate portfolio liquidity or (if the seller so agrees) to hedge against rising interest rates.
There is no assurance that this kind of put option will be available to the Trust or that selling institutions will be willing
to permit the Trust to exercise a put to hedge against rising interest rates. The Trust does not expect to assign any value to
any separate put option that may be acquired to facilitate portfolio liquidity, inasmuch as the value (if any) of the put will
be reflected in the value assigned to the associated security; any put acquired for hedging purposes would be valued in good faith
under methods or procedures established by the Trustees after consideration of all relevant factors, including its expiration date, the price
volatility of the associated security, the difference between the market price of the associated security and the exercise price
of the put, the creditworthiness of the issuer of the put and the market prices of comparable put options. Interest income generated
by certain bonds having put or demand features may be taxable.</P>

Options. </B></FONT>The Trust may enter into an agreement with a potential buyer of a municipal obligation that gives the buyer
the right, but not the obligation, to purchase a municipal obligation held by the Trust at a particular price in the future and
is commonly referred to as an over-the-counter option or OTC option. Such agreements will be entered solely to help facilitate
the selling of municipal obligations, for instance, if the buyer wishes to lock in a price for a particular municipal obligation
subject to performing due diligence on the issue or issuer. The buyer may not pay a premium for such option. There is a risk that
the value of a municipal obligation underlying an option may appreciate above the value that the buyer has agreed to pay for the
municipal obligation and therefore the Trust would not be entitled to the appreciation above such price.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Variable
and Floating Rate Debt Instruments.</B></FONT> Variable rate instruments provide for adjustments in the interest rate at specified
intervals (daily, weekly, monthly, semiannually, etc.) based on market conditions, credit ratings or interest rates and the investor
may have the right to &#8220;put&#8221; the security back to the issuer or its agent. Variable rate obligations normally provide
that the holder can demand payment of the obligation on short notice at par with accrued interest and which are frequently secured
by letters of credit or other support arrangements provided by banks. To the extent that such letters of credit or other arrangements
constitute an unconditional guarantee of the issuer&#8217;s obligations, a bank may be treated as the issuer of a security for
the purposes of complying with the diversification requirements set forth in Section 5(b) of the 1940 Act and Rule 5b-2 thereunder.
The Trust would anticipate using these bonds as cash equivalents pending longer term investment of its Trusts. The rate adjustment
features tend to limit the extent to which the market value of the obligations will fluctuate.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Residual
Interest Bonds.</B></FONT> The Trust may invest in residual interests in a trust that holds municipal securities (&#8220;inverse
floaters&#8221; also known as &#8220;residual interest bonds&#8221;). The interest rate payable on an inverse floater bears an
inverse relationship to the interest rate on another security issued by the trust. Because changes in the interest rate on the
other security inversely affect the interest paid on the inverse floater, the value and income of an inverse floater is generally
more volatile than that of a fixed rate bond. Inverse floaters have interest rate adjustment formulas that generally reduce or,
in the extreme, eliminate the interest paid to the Trust when short-term interest rates rise, and increase the interest paid to
the Trust when short-term interest rates fall. Inverse floaters have varying degrees of liquidity, and the market for these securities
is relatively volatile. These securities tend to underperform the market for fixed rate bonds in a rising long-term interest rate
environment, but tend to outperform the market for fixed rate bonds when long-term interest rates decline. Although volatile, inverse
floaters typically offer the potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality
and maturity. These securities usually permit the investor to convert the floating rate to a fixed rate (normally adjusted downward),
and this optional conversion feature may provide a partial hedge against rising rates if exercised at an opportune time. While
inverse floaters expose the Trust to leverage risk because they provide more than one dollar of bond market exposure for every
dollar invested, they are not subject to the Trust&#8217;s restrictions on borrowings.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">A tender option bond trust typically can be collapsed or closed
by the holder of the residual interest bonds (such as the Trust) or by the liquidity provider. Generally, because the Trust may
act to collapse the tender option bond trust and receive the value of the residual interest bonds held by the Trust within seven
days, such residual interest bonds are considered liquid securities when held by the Trust.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">At the discretion of the Adviser, the Trust may enter into a
so-called shortfall and forbearance agreement with respect to an inverse floater held by the Trust. The Trust generally may enter
into such agreements (i) when the liquidity provider to the tender option bond trust requires such an agreement because the level
of leverage in the tender option bond trust exceeds the level that the liquidity provider is willing support absent such an agreement;
and/or (ii) to seek to prevent the liquidity provider from collapsing the tender option bond trust in the event that the municipal
obligation held in the trust has declined in value. Such agreements commit the Trust to reimburse, upon the termination of the
trust issuing the inverse floater, the difference between the liquidation value of the underlying security (which is the basis
of the inverse floater) and the principal amount due to the holders of the floating rate security issued in conjunction with the
inverse floater. Such agreements may expose the Trust&#8217;s other assets to losses. Absent a shortfall and forbearance agreement,
the Trust would not be required to make such a reimbursement. If the Trust chooses not to enter into such an agreement, the inverse
floater could be terminated and the Trust could incur a loss. Consistent with SEC staff guidance, the Trust will segregate or earmark
liquid assets with its custodian on a mark-to-market basis to cover any such payment obligations to liquidity providers.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Interest
Rate Swaps and Forward Rate Contracts. </B></FONT>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 Trust
will only enter into interest rate swaps 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. The Trust may also enter forward rate contracts. Under
these contracts, the buyer locks in an interest rate at a future settlement date. If the interest rate on the settlement date exceeds
the lock rate, the buyer pays the seller the difference between the two rates. If the lock rate exceeds the interest rate on the
settlement date, the seller pays the buyer the difference between the two rates. Any such gain received by the Trust would be taxable.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">If the other party to an interest rate swap or forward rate contract
defaults, the Trust&#8217;s risk of loss consists of the net amount of payments that the Trust is contractually entitled to receive.
The net amount of the excess, if any, of the Trust&#8217;s obligations over its entitlements will be maintained in a segregated
account by the Trust&#8217;s custodian. The Trust will not enter into any interest rate swap or forward rate contract unless the
claims-paying ability of the other party thereto is considered to be investment grade by the investment 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. These instruments are traded in the over the counter market.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Cybersecurity
Risk.</B></FONT>&nbsp; With the increased use of technologies by Trust service providers to conduct business, such as the Internet,
the Trust is susceptible to operational, information security and related risks. The Trust relies on communications technology,
systems, and networks to engage with clients, employees, accounts, shareholders, and service providers, and a cyber incident may
inhibit the Trust&#8217;s ability to use these technologies. In general, cyber incidents can result from deliberate attacks or
unintentional events. Cyber attacks include, but are not limited to, gaining unauthorized access to digital systems (e.g., through
&#8220;hacking&#8221; or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting
data, or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized
access, such as causing denial-of-service attacks on websites. A denial-of-service attack is an effort to make network services
unavailable to intended users, which could cause shareholders to lose access to their electronic accounts, potentially indefinitely.
Employees and service providers also may not be able to access electronic systems to perform critical duties for the Trust, such
as trading and NAV calculation, during a denial-of-service attack. There is also the possibility for systems failures due to malfunctions,
user error and misconduct by employees and agents, natural disasters, or other foreseeable and unforeseeable events. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Because technology is consistently changing, new ways to carry
out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for,
or that an attack may not be detected, which puts limitations on the Trust&#8217;s ability to plan for or respond to a cyber attack.
Like other funds and business enterprises, the Trust and its service providers have experienced, and will continue to experience,
cyber incidents consistently. In addition to deliberate cyber attacks, unintentional cyber incidents can occur, such as the inadvertent
release of confidential information by the Trust or its service providers. To date, cyber incidents have not had a material adverse
effect on the Trust&#8217;s business operations or performance. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust uses third party service providers who are also
heavily dependent on computers and technology for their operations. Cybersecurity failures by or breaches of the Trust&#8217;s
investment adviser or administrator and other service providers (including, but not limited to, the custodian or transfer agent),
and the issuers of securities in which the Trust invests, may disrupt and otherwise adversely affect their business operations.
This may result in financial losses to the Trust, impede Trust trading, interfere with the Trust&#8217;s ability to calculate its
NAV, or cause violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement
or other compensation costs, litigation costs, or additional compliance costs. While many of the Trust&#8217;s service providers
have established business continuity plans and risk management systems intended to identify and mitigate cyber attacks, there are
inherent limitations in such plans and systems, including the possibility that certain risks have not been identified. The Trust
cannot control the cybersecurity plans and systems put in place by service providers to the Trust and issuers in which the Trust
invests.&nbsp; The Trust and its shareholders could be negatively impacted as a result. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Illiquid
Investments.</B></FONT> Illiquid investments may include obligations legally restricted as to resale, and may include commercial
paper issued pursuant to Section 4(a)(2) of the 1933 Act and securities eligible for resale pursuant to Rule 144A thereunder. Rule
144A securities may increase the level of portfolio illiquidity if eligible buyers become uninterested in purchasing such securities.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The secondary market for some municipal obligations issued within
a state (including issues which are privately placed with the Trust) is less liquid than that for taxable debt obligations or other
more widely traded municipal obligations. No established resale market exists for certain of the municipal obligations in which
the Trust may invest. The market for obligations rated below investment grade is also likely to be less liquid than the market
for higher rated obligations. As a result, the Trust may be unable to dispose of these municipal obligations at times when it would
otherwise wish to do so at the prices at which they are valued.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">At times, a portion of the Trust&#8217;s assets may be invested
in instruments as to which the Trust, by itself or together with other accounts managed by the Adviser and its affiliates, holds
a major portion or all of such instruments. Under adverse market or economic conditions or in the event of adverse changes in the
financial condition of the issuer, the Trust could find it more difficult to sell such instruments when the Adviser believes it
advisable to do so or may be able to sell such instruments only at prices lower than if such instruments were more widely held.
It may also be more difficult to determine the fair value of such instruments for purposes of computing the Trust&#8217;s net asset
value.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Futures
Contracts and Options on Futures Contracts.</B></FONT> A change in the level of interest rates may affect the value of the securities
held by the Trust (or of securities that the Trust expects to purchase).The Trust may enter into (i) futures contracts for the
purchase or sale of debt securities and (ii) futures contracts on securities indices. All futures contracts entered into by the
Trust are traded on exchanges or boards of trade that are licensed and regulated by the U.S. Commodity Futures Trading Commission
(&#8220;CFTC&#8221;) and must be executed through a futures commission merchant or brokerage firm which is a member of the relevant
exchange. The Trust may purchase and write call and put options on futures contracts which are traded on a United States exchange
or board of trade. The Trust will be required, in connection with transactions in futures contracts and the writing of options
on futures, to make margin deposits, which will be held by the futures commission merchant through whom the Trust engages in such
futures and options transactions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Some futures contracts and options thereon may become illiquid
under adverse market conditions. In addition, during periods of market volatility, a commodity exchange may suspend or limit transactions
in an exchange-traded instrument, which may make the instrument temporarily illiquid and difficult to price. Commodity exchanges
may also establish daily limits on the amount that the price of a futures contract or futures option can vary from the previous
day&#8217;s settlement price. Once the daily limit is reached, no trades may be made that day at a price beyond the limit. This
may prevent the Trust from closing out positions and limiting its losses.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust will engage in futures and related options transactions
for hedging purposes. The Trust will determine that the price fluctuations in the futures contracts and options on futures used
for hedging purposes are substantially related to price fluctuations in securities held by the Trust or which it expects to purchase.
The Trust will engage in transactions in futures and related options contracts only to the extent such transactions are consistent
with the requirements of the Code, for maintaining qualification of the Trust as a regulated investment company for federal income
tax purposes. The Trust has claimed an exclusion from the definition of a Commodity Pool Operator (&#8220;CPO&#8221;) under the
Commodity Exchange Act and therefore is not subject to registration or regulation as a CPO.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The regulation of derivatives has undergone substantial change
in recent years and such change may continue. In particular, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the
&#8220;Dodd-Frank Act&#8221;), and regulations proposed to be promulgated thereunder require many derivatives to be cleared and
traded on an exchange, expand entity registration requirements, impose business conduct requirements on dealers that enter into
swaps with a pension plan, endowment, retirement plan or government entity, and require banks to move some derivatives trading
units to a non-guaranteed affiliate separate from the deposit-taking bank or divest them altogether. Although the CFTC has released
final rules relating to clearing, reporting, recordkeeping, required margin and registration requirements under the legislation,
many of the provisions are subject to further final rule making, and thus its ultimate impact remains unclear. New regulations
and the implementation of existing regulations could, among other things, restrict the&nbsp;Trust&#8217;s ability to engage in
derivatives transactions (for example, by making certain types of derivatives transactions no longer available to the&nbsp;Trust)
and/or increase the costs of such derivatives transactions (for example, by increasing margin or capital requirements), and the&nbsp;Trust
may be unable to fully execute its investment strategies as a result.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The SEC has re-proposed regulations that, if adopted, could
significantly alter the Trust's regulatory obligations with regard to its derivatives usage. In particular, the proposed regulations
would impose value at risk limitations on the Trust's use of derivatives, eliminate the current asset segregation framework for
covering derivatives and certain other financial instruments, require the Trust's Board to adopt a derivative risk management program,
impose new responsibilities on the Board and establish new reporting and recordkeeping requirements. Implementations of these proposed
regulatory requirements may limit the ability of the Trust to use derivative instruments as part of its investment strategy, increase
the costs of using these instruments or make them less effective. Limits or restrictions applicable to the counterparties with
which the Trust engages in derivative transactions also could prevent the Trust from using these instruments or affect the pricing
or other factors relating to these instruments, or may change the availability of certain investments.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Legislation may be enacted that could negatively affect the assets
of the&nbsp;Trust. Legislation or regulation may also change the way in which the&nbsp;Trust itself is regulated. The effects of
any new governmental regulation cannot be predicted and there can be no assurance that any new governmental regulation will not
adversely affect the&nbsp;Trust&#8217;s ability to achieve its investment objective(s).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>LIBOR
Transition and Associated Risk.</B></FONT> The London Interbank Offered Rate (&#8220;LIBOR&#8221;) is the average offered rate
for various maturities of short-term loans between major international banks who are members of the British Bankers Association
(BBA). LIBOR is the most common benchmark interest rate index used to make adjustments to variable-rate loans. It is used throughout
global banking and financial industries to determine interest rates for a variety of financial instruments (such as debt instruments
and derivatives) and borrowing arrangements, and to determine dividend rates for preferred shares. However, the use of LIBOR started
to come under pressure following manipulation allegations in 2012. Despite increased regulation and other corrective actions since
that time, concerns have arisen regarding its viability as a benchmark, due largely to reduced activity in the financial markets
that it measures.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In June 2017, the Alternative Reference Rates Committee, a group
of large U.S. banks working with the Federal Reserve, announced its selection of a new Secured Overnight Financing Rate (&#8220;SOFR&#8221;),
which is intended to be a broad measure of secured overnight U.S. Treasury repo rates, as an appropriate replacement for LIBOR.
The Federal Reserve Bank of New York began publishing the SOFR earlier in 2018, with the expectation that it could be used on a
voluntary basis in new instruments and transactions. Bank working groups and regulators in other countries have suggested other
alternatives for their markets, including the Sterling Overnight Interbank Average Rate (&#8220;SONIA&#8221;) in England.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In July 2017, the Financial Conduct Authority (the &#8220;FCA&#8221;),
the United Kingdom financial regulatory body, announced that after 2021 it will cease its active encouragement of UK banks to provide
the quotations needed to sustain LIBOR. That announcement suggests that LIBOR may cease to be published after that time.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Various financial industry groups have begun planning for that
transition, but there are obstacles to converting certain longer term securities and transactions to a new benchmark. Transition
planning is at an early stage, and neither the effect of the transition process nor its ultimate success can yet be known. The
transition process might lead to increased volatility and illiquidity in markets that currently rely on the LIBOR to determine
interest rates. Although the period from the FCA announcement until the end of 2021 is generally expected to be enough time for
market participants to transition to the use of a different benchmark for new securities and transactions, there remains uncertainty
regarding the future utilization of LIBOR and the specific replacement rate or rates. As such, the potential effect of a transition
away from LIBOR on the Trust or the financial instruments utilized by the Trust cannot yet be determined. The transition process
may involve, among other things, increased volatility or illiquidity in markets for instruments that currently rely on LIBOR. The
transition may also result in a change in (i) the value of certain instruments held by the Trust, (ii) the cost of borrowing or
the dividend rate for preferred shares or (iii) the effectiveness of related Trust transactions such as hedges, as applicable.
When LIBOR is discontinued, the LIBOR replacement rate may be lower than market expectations, which could have an adverse impact
on the value of preferred and debt-securities with floating or fixed-to-floating rate coupons. Any such effects of the transition
away from LIBOR, as well as other unforeseen effects, could result in losses to the Trust. Since the usefulness of LIBOR as a benchmark
could deteriorate during the transition period, these effects could occur prior to the end of 2021.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Asset
Coverage Requirements.</B></FONT> To the extent required by SEC guidance, if a transaction creates a future obligation of the Trust
to another party the Trust will: (1) cover the obligation by entering into an offsetting position or transaction; and/or (2) segregate
cash and/or liquid securities with a value (together with any collateral posted with respect to the obligation) at least equal
to the marked-to-market value of the obligation. Assets used as cover or segregated cannot be sold while the position(s) requiring
coverage is open unless replaced with other appropriate assets. As a result, if a large portion of assets is segregated or committed
as cover, it could impede portfolio management. The types of transactions that may require asset coverage include (but are not
limited to) forward contracts, certain options, forward commitments, futures contracts, when-issued securities, swap agreements
and residual interest bonds.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Temporary
Investments.</B></FONT> The Trust may invest in cash equivalents to invest daily cash balances or for temporary defensive purposes.
Cash equivalents are highly liquid, short-term securities such as commercial paper, time deposits, certificates of deposit, short-term
notes and short-term U.S. Government obligations. These securities may be subject to federal income, state income and/or other
taxes. During unusual market conditions, the Trust may invest up to 100% of its assets in cash or cash equivalents temporarily,
which may be inconsistent with its investment objectives and other policies.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Portfolio
Trading and Turnover Rate.</B></FONT> A change in the securities held by the Trust is known as &#8220;portfolio turnover&#8221;
and generally involves expense to the Trust, including brokerage commissions or dealer markups and other transaction costs on both
the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Trust
to realize net short-term capital gains, such gains will be taxable as ordinary income to taxable shareholders. Portfolio turnover
rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value
of portfolio securities &#8722; excluding securities whose maturities at acquisition were one year or less. The Trust's portfolio
turnover rate is not a limiting factor when the Adviser considers a change in the Trust's portfolio holdings. The portfolio turnover
rate(s) for the Trust for the fiscal years ended March 31, 2020 and March 31, 2019 were 44% and 17%, respectively.</P>

is responsible for the overall management and supervision of the affairs of the Trust. The Board members and officers of the Trust
are listed below. Except as indicated, each individual has held the office shown or other offices in the same company for the last
five years. Each Trustee holds office until the annual meeting for the year in which his or her term expires and until his or her
successor is elected and qualified, subject to a prior death, resignation, retirement, disqualification or removal. Under the terms
of the Trust&#8217;s current Trustee retirement policy, an Independent Trustee must retire and resign as a Trustee on the earlier
of: (i) the first day of July following his or her 74th birthday; or (ii), with limited exception, December 31st of the 20th year
in which he or she has served as a Trustee. However, if such retirement and resignation would cause the Trust to be out of compliance
with Section 16 of the Investment Company Act of 1940, as amended (the &#8220;1940 Act&#8221;) or any other regulations or guidance
of the Securities and Exchange Commission (&#8220;SEC&#8221;), then such retirement and resignation will not become effective until
such time as action has been taken for the Trust to be in compliance therewith. The &#8220;noninterested Trustees&#8221; consist
of those Trustees who are not &#8220;interested persons&#8221; of the Trust, as that term is defined under the 1940 Act. The business
address of each Board member and officer is Two International Place, Boston, Massachusetts 02110. As used in this SAI, &#8220;EVC&#8221;
refers to Eaton Vance Corp., &#8220;EV&#8221; refers to Eaton Vance, Inc., &#8220;BMR&#8221; refers to Boston Management and Research
and &#8220;EVD&#8221; refers to Eaton Vance Distributors Inc. EVC and EV are the corporate parent and trustee, respectively, of
Eaton Vance and BMR. EVD is a wholly-owned subsidiary of EVC. Each officer affiliated with Eaton Vance may hold a position with
other Eaton Vance affiliates that is comparable to his or her position with Eaton Vance listed below.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Board has general oversight responsibility with respect to
the business and affairs of the Trust. The Board has engaged an investment adviser and (if applicable) a sub-adviser(s) (collectively
the &#8220;adviser&#8221;) to manage the&nbsp;Trust and an administrator to administer the&nbsp;Trust and is responsible for overseeing
such adviser and administrator and other service providers to the Trust. The Board is currently composed of eleven Trustees, including
ten Trustees who are not &#8220;interested persons&#8221; of the&nbsp;Trust, as that term is defined in the 1940 Act (each a &#8220;noninterested
Trustee&#8221;). In addition to six regularly scheduled meetings per year, the Board holds special meetings or informal conference
calls to discuss specific matters that may require action prior to the next regular meeting. As discussed below, the Board has
established six committees to assist the Board in performing its oversight responsibilities.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Board has appointed a noninterested Trustee to serve in the
role of Chairperson. The Chairperson&#8217;s primary role is to participate in the preparation of the agenda for meetings of the
Board and the identification of information to be presented to the Board with respect to matters to be acted upon by the Board.
The Chairperson also presides at all meetings of the Board and acts as a liaison with service providers, officers, attorneys, and
other Board members generally between meetings. The Chairperson may perform such other functions as may be requested by the Board
from time to time. In addition, the Board may appoint a noninterested Trustee to serve in the role of Vice-Chairperson. The Vice-Chairperson
has the power and authority to perform any or all of the duties and responsibilities of the Chairperson in the absence of the Chairperson
and/or as requested by the Chairperson. Except for any duties specified herein or pursuant to the Trust&#8217;s Declaration of
Trust or By-laws, the designation of Chairperson or Vice-Chairperson does not impose on such noninterested Trustee any duties,
obligations or liability that is greater than the duties, obligations or liability imposed on such person as a member of the Board,
generally.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust is subject to a number of risks, including, among others,
investment, compliance, operational, and valuation risks. Risk oversight is part of the Board&#8217;s general oversight of the
Trust and is addressed as part of various activities of the Board and its Committees. As part of its oversight of the Trust, the
Board directly, or through a Committee, relies on and reviews reports from, among others, Trust management, the adviser, the administrator,
the principal underwriter, the Chief Compliance Officer (the &#8220;CCO&#8221;), and other Trust service providers responsible
for day-to-day oversight of Trust investments, operations and compliance to assist the Board in identifying and understanding the
nature and extent of risks and determining whether, and to what extent, such risks can or should be mitigated. The Board also interacts
with the CCO and with senior personnel of the adviser, administrator, principal underwriter and other Trust service providers and
provides input on risk management issues during meetings of the Board and its Committees. Each of the adviser, administrator, principal
underwriter and the other Trust service providers has its own, independent interest and responsibilities in risk management, and
its policies and methods for carrying out risk management functions will depend, in part, on its individual priorities, resources
and controls. It is not possible to identify all of the risks that may affect the&nbsp;Trust or to develop processes and controls
to eliminate or mitigate their occurrence or effects. Moreover, it is necessary to bear certain risks (such as investment-related
risks) to achieve the&nbsp;Trust&#8217;s goals.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Board, with the assistance of management and with input from
the Board's various committees, reviews investment policies and risks in connection with its review of Trust performance. The Board
has appointed a Trust CCO who oversees the implementation and testing of the Trust compliance program and reports to the Board
regarding compliance matters for the Trust and its principal service providers. In addition, as part of the Board&#8217;s periodic
review of the advisory, subadvisory (if applicable), distribution and other service provider agreements, the Board may consider
risk management aspects of their operations and the functions for which they are responsible. With respect to valuation, the Board
approves and periodically reviews valuation policies and procedures applicable to valuing the&nbsp;Trust&#8217;s shares. The administrator,
the investment adviser and the sub-adviser (if applicable) are responsible for the implementation and day-to-day administration
of these valuation policies and procedures and provides reports to the Audit Committee of the Board and the Board regarding these
and related matters. In addition, the Audit Committee of the Board or the Board receives reports periodically from the independent
public accounting firm for the Trust regarding tests performed by such firm on the valuation of all securities, as well as with
respect to other risks associated with mutual funds. Reports received from service providers, legal counsel and the independent
public accounting firm assist the Board in performing its oversight function.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust&#8217;s Declaration of Trust&nbsp;does not set forth
any specific qualifications to serve as a Trustee. The Charter of the Governance Committee also does not set forth any specific
qualifications, but does set forth certain factors that the Committee may take into account in considering noninterested Trustee
candidates. In general, no one factor is decisive in the selection of an individual to join the Board. Among the factors the Board
considers when concluding that an individual should serve on the Board are the following: (i) knowledge in matters relating to
the mutual fund industry; (ii) experience as a director or senior officer of public companies; (iii) educational background; (iv)
reputation for high ethical standards and professional integrity; (v) specific financial, technical or other expertise, and the
extent to which such expertise would complement the Board members&#8217; existing mix of skills, core competencies and qualifications;
(vi) perceived ability to contribute to the ongoing functions of the Board, including the ability and commitment to attend meetings
regularly and work collaboratively with other members of the Board; (vii) the ability to qualify as a noninterested Trustee for
purposes of the 1940 Act and any other actual or potential conflicts of interest involving the individual and the Trust; and (viii)
such other factors as the Board determines to be relevant in light of the existing composition of the Board.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Among the attributes or skills common to all Board members are
their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the
other members of the Board, management, sub-advisers, other service providers, counsel and independent registered public accounting
firms, and to exercise effective and independent business judgment in the performance of their duties as members of the Board.
Each Board member&#8217;s ability to perform his or her duties effectively has been attained through the Board member&#8217;s business,
consulting, public service and/or academic positions and through experience from service as a member of the Boards of the Eaton
Vance family of funds (&#8220;Eaton Vance Fund Boards&#8221;) (and/or in other capacities, including for any predecessor funds),
public companies, or non-profit entities or other organizations as set forth below. Each Board member&#8217;s ability to perform
his or her duties effectively also has been enhanced by his or her educational background, professional training, and/or other
life experiences.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In respect of each current member of the Board, the individual&#8217;s
substantial professional accomplishments and experience, including in fields related to the operations of registered investment
companies, were a significant factor in the determination that the individual should serve as a member of the Board. The following
is a summary of each Board member&#8217;s particular professional experience and additional considerations that contributed to
the Board&#8217;s conclusion that he or she should serve as a member of the Board:</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">It is possible that conflicts of interest may arise in connection
with a portfolio manager&#8217;s management of Trust&#8217;s investments on the one hand and the investments of other accounts
for which a portfolio manager is responsible on the other. For example, a portfolio manager may have conflicts of interest in allocating
management time, resources and investment opportunities among Trust and other accounts she advises. In addition, due to differences
in the investment strategies or restrictions between Trust and the other accounts, the portfolio manager may take action with respect
to another account that differs from the action taken with respect to Trust. In some cases, another account managed by a portfolio
manager may compensate the investment adviser based on the performance of the securities held by that account. The existence of
such a performance based fee may create additional conflicts of interest for the portfolio manager in the allocation of management
time, resources and investment opportunities. Whenever conflicts of interest arise, the portfolio manager will endeavor to exercise
her discretion in a manner that she believes is equitable to all interested persons. The investment adviser has adopted several
policies and procedures designed to address these potential conflicts including a code of ethics and policies that govern the investment
adviser's trading practices, including among other things the aggregation and allocation of trades among clients, brokerage allocations,
cross trades and best execution.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><I>Compensation
Structure for Eaton Vance. </I></FONT> Compensation of the Adviser's portfolio managers and other investment professionals has
the following primary components: (1) a base salary, (2) an annual cash bonus, (3) annual non-cash compensation consisting of options
to purchase shares of EVC nonvoting common stock and/or restricted shares of EVC nonvoting common stock that generally are subject
to a vesting schedule, and (4) (for equity portfolio managers) a Deferred Alpha Incentive Plan, which pays a deferred cash award
tied to future excess returns in certain equity strategy portfolios. The Adviser&#8217;s investment professionals also receive
certain retirement, insurance and other benefits that are broadly available to the Adviser&#8217;s employees. Compensation of the
Adviser&#8217;s investment professionals is reviewed primarily on an annual basis. Cash bonuses, stock-based compensation awards,
and adjustments in base salary are typically paid or put into effect at or shortly after the October 31st fiscal year end of EVC.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><I>Method
to Determine Compensation.</I></FONT> The Adviser compensates its portfolio managers based primarily on the scale and complexity
of their portfolio responsibilities and the total return performance of managed funds and accounts versus the benchmark(s) stated
in the prospectus, as well as an appropriate peer group (as described below). In addition to rankings within peer groups of funds
on the basis of absolute performance, consideration may also be given to relative risk-adjusted performance. Risk-adjusted performance
measures include, but are not limited to Sharpe ratio, which uses standard deviation and excess return to determine reward per
unit of risk. Performance is normally based on periods ending on the September 30th preceding fiscal year end. Trust performance
is normally evaluated primarily versus peer groups of funds as determined by Lipper Inc. and/or Morningstar, Inc. When a fund&#8217;s
peer group as determined by Lipper or Morningstar is deemed by the Adviser&#8217;s management not to provide a fair comparison,
performance may instead be evaluated primarily against a custom peer group or market index. In evaluating the performance of a
fund and its manager, primary emphasis is normally placed on three-year performance, with secondary consideration of performance
over longer and shorter periods. For funds that are tax-managed or otherwise have an objective of after-tax returns, performance
is measured net of taxes. For other funds, performance is evaluated on a pre-tax basis. For funds with an investment objective
other than total return (such as current income), consideration will also be given to the fund&#8217;s success in achieving its
objective. For managers responsible for multiple funds and accounts, investment performance is evaluated on an aggregate basis,
based on averages or weighted averages among managed funds and accounts. Funds and accounts that have performance-based advisory
fees are not accorded disproportionate weightings in measuring aggregate portfolio manager performance. A portion of the compensation
payable to equity portfolio managers and investment professionals will be determined based on the ability of one or more accounts
managed by such manager, that are not advised by CRM to achieve a specified target average annual gross return over a three year
period in excess of the account benchmark. The cash award to be payable at the end of the three year term will be established at
the inception of the term and will be adjusted positively or negatively to the extent that the average annual gross return varies
from the specified target return. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The compensation of portfolio managers with other job responsibilities
(such as heading an investment group or providing analytical support to other portfolios) will include consideration of the scope
of such responsibilities and the managers&#8217; performance in meeting them.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Adviser seeks to compensate portfolio managers commensurate
with their responsibilities and performance, and competitive with other firms within the investment management industry. The Adviser
participates in investment-industry compensation surveys and utilizes survey data as a factor in determining salary, bonus and
stock-based compensation levels for portfolio managers and other investment professionals. Salaries, bonuses and stock-based compensation
are also influenced by the operating performance of the Adviser and its parent company. The overall annual cash bonus pool is generally
based on a substantially fixed percentage of pre-bonus adjusted operating income. While the salaries of the Adviser&#8217;s portfolio
managers are comparatively fixed, cash bonuses and stock-based compensation may fluctuate significantly from year to year, based
on changes in manager performance and other factors as described herein. For a high performing portfolio manager, cash bonuses and stock-based
compensation may represent a substantial portion of total compensation.</P>

the foregoing methodologies are valued at fair value using methods determined in good faith by or at the direction of the members
of the Board. Such methods may include consideration of relevant factors, including but not limited to (i) the type of security
and, the existence of any contractual restrictions on the security&#8217;s disposition; (ii) the price and extent of public trading
in similar securities of the issuer or of comparable companies or entities; (iii) quotations or relevant information obtained from
broker-dealers or other market participants; (iv) information obtained from the issuer, analysts, and/or the appropriate stock

an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold; (vii) any
transaction involving the issuer of such securities; and (viii) any other factors deemed relevant by the investment adviser. For
purposes of fair valuation, the portfolio managers of one Eaton Vance fund that invests in Senior and Junior Loans may not possess
the same information about a Senior or Junior Loan as the portfolio managers of another Eaton Vance fund. As such, at times the
fair value of a Loan determined by certain Eaton Vance portfolio managers may vary from the fair value of the same Loan determined
by other portfolio managers.</P>

utilizing the amortized cost valuation technique in accordance with Rule 2a-7 under the 1940 Act. This technique involves initially
valuing a portfolio security at its cost and thereafter assuming a constant amortization to maturity of any discount or premium.
If amortized cost is determined not to approximate fair value, Cash Reserves Fund may value its investment securities in the same

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Decisions concerning the execution of portfolio security transactions,
including the selection of the market and the broker-dealer firm, are made by the investment adviser. The Trust is responsible
for the expenses associated with its portfolio transactions. The investment adviser is also responsible for the execution of transactions
for all other accounts managed by it. The investment adviser places the portfolio security transactions for execution with one
or more broker-dealer firms. The investment adviser uses its best efforts to obtain execution of portfolio security transactions
at prices which in the investment adviser&#8217;s judgment are advantageous to the client and at a reasonably competitive spread
or (when a disclosed commission is being charged) at reasonably competitive commission rates. In seeking such execution, the investment
adviser will use its best judgment in evaluating the terms of a transaction, and will give consideration to various relevant factors,
which may include, without limitation, the full range and quality of the broker-dealer firm&#8217;s services, responsiveness of
the firm to the investment adviser, the size and type of the transaction, the nature and character of the market for the security,
the confidentiality, speed and certainty of effective execution required for the transaction, the general execution and operational
capabilities of the broker-dealer firm, the reputation, reliability, experience and financial condition of the firm, the value
and quality of the services rendered by the firm in this and other transactions, and the amount of the spread or commission, if
any. In addition, the investment adviser may consider the receipt of Research Services (as defined below), provided it does not
compromise the investment adviser&#8217;s obligation to seek best overall execution for the&nbsp;Trust and is otherwise in compliance
with applicable law. The investment adviser may engage in portfolio brokerage transactions with a broker-dealer firm that sells
shares of Eaton Vance funds, provided such transactions are not directed to that firm as compensation for the promotion or sale
of such shares.</P>

a brokerage commission. Although spreads or commissions on portfolio security transactions will, in the judgment of the investment
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&nbsp;Trust and the investment

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Pursuant to the safe harbor provided in Section 28(e) of the
Securities Exchange Act of 1934, as amended (&#8220;Section 28(e)&#8221;) and to the extent permitted by other applicable law,
a broker or dealer who executes a portfolio transaction may receive a commission that is in excess of the amount of commission
another broker or dealer would have charged for effecting that transaction if the investment adviser determines in good faith that
such compensation was reasonable in relation to the value of the brokerage and research services provided. This determination may
be made on the basis of either that particular transaction or on the basis of the overall responsibility which the investment adviser
and its affiliates have for accounts over which they exercise investment discretion. &#8220;Research Services&#8221; as used herein
includes any and all brokerage and research services to the extent permitted by Section 28(e) and other applicable law. Generally,
Research Services may include, but are not limited to, such matters as research, analytical and quotation services, data, information
and other services products and materials which assist the investment adviser in the performance of its investment responsibilities.
More specifically, Research Services may include general economic, political, business and market information, industry and company
reviews, evaluations of securities and portfolio strategies and transactions, technical analysis of various aspects of the securities
markets, recommendations as to the purchase and sale of securities and other portfolio transactions, certain financial, industry
and trade publications, certain news and information services, and certain research oriented computer software, data bases and
services. Any particular Research Service obtained through a broker-dealer may be used by the investment adviser in connection
with client accounts other than those accounts which pay commissions to such broker-dealer, to the extent permitted by applicable
law. Any such Research Service may be broadly useful and of value to the investment adviser in rendering investment advisory services
to all or a significant portion of its clients, or may be relevant and useful for the management of only one client&#8217;s account
or of a few clients&#8217; accounts, or may be useful for the management of merely a segment of certain clients&#8217; accounts,
regardless of whether any such account or accounts paid commissions to the broker-dealer through which such Research Service was
obtained. The investment adviser evaluates the nature and quality of the various Research Services obtained through broker-dealer
firms and, to the extent permitted by applicable law, may attempt to allocate sufficient portfolio security transactions to such
firms to ensure the continued receipt of Research Services which the investment adviser believes are useful or of value to it in
rendering investment advisory services to its clients. The investment adviser may also receive brokerage and Research Services
from underwriters and dealers in fixed-price offerings, when permitted under applicable law.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Research Services provided by (and produced by) broker-dealers
that execute portfolio transactions or from affiliates of executing broker-dealers are referred to as &#8220;Proprietary Research.&#8221;
Except for trades executed in jurisdictions where such consideration is not permissible, the investment adviser may and does consider
the receipt of Proprietary Research Services as a factor in selecting broker dealers to execute client portfolio transactions,
provided it does not compromise the investment adviser&#8217;s obligation to seek best overall execution. In jurisdictions where
permissible, the investment adviser also may consider the receipt of Research Services under so called &#8220;client commission
arrangements&#8221; or &#8220;commission sharing arrangements&#8221; (both referred to as &#8220;CCAs&#8221;) as a factor in selecting
broker dealers to execute transactions, provided it does not compromise the investment adviser&#8217;s obligation to seek best
overall execution. Under a CCA arrangement, the investment adviser may cause client accounts to effect transactions through a broker-dealer
and request that the broker-dealer allocate a portion of the commissions paid on those transactions to a pool of commission credits
that are paid to other firms that provide Research Services to the investment adviser. Under a CCA, the broker-dealer that provides
the Research Services need not execute the trade. Participating in CCAs may enable the investment adviser to consolidate payments
for research using accumulated client commission credits from transactions executed through a particular broker-dealer to periodically
pay for Research Services obtained from and provided by other firms, including other broker-dealers that supply Research Services.
The investment adviser believes that CCAs offer the potential to optimize the execution of trades and the acquisition of a variety
of high quality Research Services that the investment adviser might not be provided access to absent CCAs. The investment adviser
will only enter into and utilize CCAs to the extent permitted by Section 28(e) and other applicable law.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The investment companies sponsored by the investment adviser
or its affiliates also may allocate trades in such offerings to acquire information relating to the performance, fees and expenses
of such companies and other investment companies, which information is used by the members of the Board of such companies to fulfill
their responsibility to oversee the quality of the services provided to various entities, including the investment adviser, to
such companies. Such companies may also pay cash for such information.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Municipal obligations considered as investments for the Trust
may also be appropriate for other investment accounts managed by the investment adviser or its affiliates. Whenever decisions are
made to buy or sell securities by the Trust and one or more of such other accounts simultaneously, the investment adviser will
allocate the security transactions (including &#8220;new&#8221; 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 investment 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
members of the Board that the benefits from the investment adviser organization outweigh any disadvantage that may arise from exposure
to simultaneous transactions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The discussions below and certain disclosure in the Prospectus
provide general tax information related to an investment in the shares. Because tax laws are complex and often change, you should
consult your tax advisor about the tax consequences of an investment in the Trust. Unless otherwise noted, the following tax discussion
assumes that you are a U.S. person that is not subject to special rules under the Code, and that you hold the shares as a capital
asset (generally, property held for investment).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust has elected to be treated and intends to qualify
each year as a regulated investment company (a &#8220;RIC&#8221;) under Subchapter M the Code. Accordingly, the Trust intends to
satisfy certain requirements relating to sources of its income and diversification of its assets and to distribute substantially
all of its net investment income (including both investment company taxable income and net tax-exempt interest income (which includes
net short-term capital gain after reduction by net long-term capital losses and any available capital loss carryforwards) in accordance
with the timing requirements imposed by the Code, so as to maintain its RIC status and generally to avoid paying federal income
or excise tax thereon. If it qualifies for treatment as a RIC and satisfies the above-mentioned distribution requirements, the
Trust will not be subject to federal income tax on income paid to its shareholders in the form of dividends or capital gains distributions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">To qualify as a RIC for federal income tax purposes, the Trust
must derive at least 90% of its annual gross income from dividends, interest, payments with respect to securities loans, gains
from the sale or other disposition of stock, securities or foreign currencies, or other income (including, but not limited to,
gains from options, futures or forward contracts) derived with respect to its business of investing in stock, securities and currencies,
and net income derived from an interest in a &#8220;qualified publicly traded partnership&#8221; (as defined in the Code). The
Trust must also distribute to its shareholders at least the sum of 90% of its investment company taxable income and 90% of its
net tax-exempt interest income for each taxable year.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust must also satisfy certain requirements with respect
to the diversification of its assets. The Trust must have, at the close of each quarter of its taxable year, at least 50% of the
value of its total assets represented by cash and cash items, U.S. government securities, securities of other RICs, and other
securities that, in respect of any one issuer, do not represent more than 5% of the value of the assets of the Trust or more than
10% of the voting securities of that issuer. In addition, at those times, not more than 25% of the value of the Trust&#8217;s
assets may be invested, including through corporations in which the Trust owns a 20% or more voting stock interest, in securities
(other than U.S. Government securities or the securities of other RICs) of any one issuer, or of two or more issuers that the
Trust controls and which are engaged in the same or similar trades or businesses or related trades or businesses, or of one or
more qualified publicly traded partnerships.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In order to avoid incurring a nondeductible 4% federal excise
tax obligation, the Code requires that the Trust distribute (or be deemed to have distributed) by December 31 of each calendar
year an amount at least equal to the sum of (i) 98% of its ordinary income for such year, (ii) 98.2% of its capital gain net income
(which is the excess of its capital gain over its capital loss), generally computed on the basis of the one-year period ending
on October 31 of such year (or later if the Trust is permitted and so elects), after reduction by any available capital loss carryforwards
and (iii) 100% of any ordinary income and capital gain net income from the prior year (as previously computed) that were not paid
out during such year and on which the Trust paid no federal income tax.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">If the Trust does not qualify as a RIC for any taxable year,
the Trust&#8217;s taxable income will be subject to corporate income taxes, and all distributions from earnings and profits, including
distributions of net capital gain (if any), will be taxable to the shareholder as ordinary income. Such distributions will be treated
as qualified dividend income with respect to shareholders who are individuals and will be eligible for the dividends received deduction
in the case of shareholders taxed as corporations, provided, in each case, certain holding period and other requirements are met.
In order to requalify for taxation as a RIC, the Trust may be required to recognize unrealized gains, pay substantial taxes and
interest, and make substantial distributions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust intends to invest a sufficient portion of its assets
in tax-exempt municipal obligations so that it will be permitted to pay &#8220;exempt-interest dividends&#8221; (as defined under
applicable federal income tax law). Each distribution of exempt-interest dividends, whether paid in cash or in the form of additional
shares of the Trust, ordinarily will constitute income exempt from regular federal income tax under current federal tax law, but
it may be subject to state and local taxes. Interest on certain municipal obligations, such as certain private activity bonds,
however, is included as an item of tax preference in determining the amount of a taxpayer&#8217;s alternative minimum taxable income.
To the extent that the Trust receives income from such municipal obligations, a portion of the dividends paid by the Trust, although
exempt from regular federal income tax, will be taxable to shareholders to the extent that their tax liability is determined under
the alternative minimum tax (&#8220;AMT&#8221;). Furthermore, exempt-interest dividends are included in determining what portion,
if any, of a person&#8217;s social security and railroad retirement benefits will be includible in gross income subject to regular
federal income tax. </P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In addition to exempt-interest dividends, the Trust also may
distribute to its shareholders amounts that are treated as long-term capital gain or ordinary income (which may include short-term
capital gains). These distributions are generally subject to federal, state and local taxation, depending on a shareholder&#8217;s
situation. Taxable distributions are taxable whether shareholders receive them in cash or in the form of additional shares. A shareholder
whose distributions are paid in the form of additional shares under the Dividend Reinvestment Plan generally will be treated as
having received a dividend equal to either (i) if the shares are trading below net asset value, the amount of cash allocated to
the shareholder for the purchase of shares on its behalf in the open market, or (ii) if shares are trading at or above net asset
value, generally the fair market value of the new shares issued to the shareholder.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">At least annually, the Trust intends to distribute any net capital
gain (which is the excess of net long-term capital gain over net short-term capital loss), if any, or, alternatively, to retain
all or a portion of the year&#8217;s net capital gain and pay federal income tax on the retained gain.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Net capital gain distributions designated as capital gains
dividends are generally taxable at rates applicable to long-term capital gains regardless of how long a shareholder has held his
or her shares.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">If the Trust retains any net capital gain or investment company
taxable income, it will be subject to tax at regular corporate rates on the amount retained. If the Trust retains any net capital
gain, it may report the retained amount as undistributed capital gains in a timely notice to its shareholders who, if subject to
federal income tax on long-term capital gains, (i) will be required to include in income for federal income tax purposes, as long-term
capital gain, their share of such undistributed amount; (ii) will be entitled to credit their proportionate shares of the tax paid
by the Trust on such undistributed amount against their federal income tax liabilities, if any; and (iii) will be entitled to claim
refunds to the extent the credit exceeds such liabilities. For. federal income tax purposes, the tax basis of shares owned by a
shareholder of the Trust will be increased by an amount equal to the difference between the amount of undistributed capital gains
included in the shareholder&#8217;s gross income and the tax deemed paid by the shareholder under clauses (ii) and (iii) of the
preceding sentence. The Trust is not required to, and there can be no assurance the Trust will, make this designation if it retains
all or a portion of its net capital gain in a taxable year.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">If the Trust makes a distribution to a shareholder in excess
of the Trust&#8217;s current and accumulated earnings and profits in any taxable year, the excess distribution will be treated
as a return of capital to the extent of such shareholder&#8216;s tax basis in its shares, and thereafter as capital gain. A return
of capital is not taxable, but it reduces a shareholder&#8217;s tax basis in its shares, thus reducing any loss or increasing any
gain on a subsequent taxable disposition by the shareholder of its shares.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Internal Revenue Service (&#8220;IRS&#8221;) currently requires
that a RIC that has two or more classes of stock allocate to each such class proportionate amounts of each type of its income (such
as exempt interest, ordinary income and capital gains). Accordingly, if the Trust issues preferred shares, it will designate dividends
made with respect to shares and preferred shares as consisting of particular types of income (e.g., exempt interest, net capital
gain and ordinary income) in accordance with the proportionate share of each class in the total dividends paid by the Trust during
the year.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Dividends and other taxable distributions declared by the Trust
in October, November or December to shareholders of record on a specified date in such month and paid during the following January
will be treated as having been received by shareholders in the year the distributions were declared.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Each shareholder will receive an annual statement summarizing
the source and tax status of all distributions (including net capital gains credited to the shareholder but retained by the Trust)
after the close of the Trust&#8217;s taxable year.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The sale or exchange of shares normally will result in capital
gain or loss to shareholders. Generally a shareholder&#8217;s gain or loss will be long-term capital gain or loss if the shares
have been held for more than one year, and short-term capital gain or loss if the shares are held for one year or less. Any loss
on the sale of shares that have been held for six months or less will be disallowed to the extent of any distribution of exempt-interest
dividends received with respect to such shares, unless the shares are of a RIC that declares exempt-interest dividends on a daily
basis in an amount equal to at least 90% of its net tax-exempt interest and distributes such dividends on a monthly or more frequent
basis. If a shareholder sells or otherwise disposes of shares before holding them for more than six months, any loss on the sale
or disposition will be treated as a long-term capital loss to the extent of any net capital gain dividends received by the shareholder
on such shares. Any loss realized on a sale or exchange of shares of the Trust will be disallowed to the extent those shares of
the Trust are replaced by other substantially identical shares of the Trust or other substantially identical stock or securities
(including through reinvestment of dividends) within a period of 61 days beginning 30 days before and ending 30 days after the
date of disposition of the original shares. In that event, the basis of the replacement shares of the Trust will be adjusted to
reflect the disallowed loss.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">From time to time, the Trust may make a tender offer for its
shares. Shareholders who tender all shares held, or considered to be held, by them will be treated as having sold their shares
and generally will realize a capital gain or loss. If a shareholder tenders fewer than all or its shares, such shareholder may
be treated as having received a distribution under Section 301 of the Code (&#8220;Section 301 distribution&#8221;) unless the
redemption is treated as being either (i) &#8220;substantially disproportionate&#8221; with respect to such shareholder or (ii)
otherwise &#8220;not essentially equivalent to a dividend&#8221; under the relevant rules of the Code. A Section 301 distribution
is not treated as a sale or exchange giving rise to a capital gain or loss, but rather is treated as a dividend to the extent supported
by the Trust&#8217;s current and accumulated earnings and profits, with the excess treated as a return of capital reducing the
shareholder&#8217;s tax basis in the Trust shares, and thereafter as capital gain. Where a redeeming shareholder is treated as
receiving a dividend, there is a risk that non-tendering shareholders whose interests in the Trust increase as a result of such
tender will be treated as having received a distribution from the Trust. The extent of such risk will vary depending upon the particular
circumstances of the tender offer, in particular whether such offer is a single and isolated event or is part of a plan for periodically
redeeming the shares of the Trust; if isolated, any such risk is likely remote.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Sales charges paid upon a purchase of shares cannot be taken
into account for purposes of determining gain or loss on a sale of the shares before the 91st day after their purchase to the extent
a sales charge is reduced or eliminated in a subsequent acquisition of shares of the Trust, during the period beginning on the
date of such sale and ending on January 31 of the calendar year following the calendar year in which such sale was made, pursuant
to a reinvestment or exchange privilege. Any disregarded amounts will result in an adjustment to the shareholder&#8217;s tax basis
in some or all of any other shares acquired.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">An investor should be aware that, if shares are purchased shortly
before the record date for any taxable dividend (including a capital gain dividend), the purchase price likely will reflect the
value of the dividend 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. An investor should also be aware that the benefits of the
reduced tax rate applicable to long-term capital gains may be impacted by the application of the AMT to individual shareholders.
Further, entities or persons who are &#8220;substantial users&#8221; (or persons related to &#8220;substantial users&#8221;) of
facilities financed by industrial development or private activity bonds should consult their tax advisers before purchasing shares
of the Trust. &#8220;Substantial user&#8221; is defined in applicable Treasury regulations to generally include a &#8220;non-exempt
person&#8221; who regularly uses in its trade or business a part of a facility financed from the proceeds
of industrial development bonds, and the same definition should apply in the case of private activity bonds.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Any interest on indebtedness incurred or continued to purchase
or carry the Trust&#8217;s shares to which exempt-interest dividends are allocated is not deductible by shareholders for U.S. federal
income tax purposes in proportion to the percentage that the Trust's distribution of exempt-interest dividends bears to all of
the Trust's distributions, excluding capital gain dividends. Under certain applicable rules, the purchase or ownership of shares
may be considered to have been made with borrowed funds even though such funds are not directly used for the purchase or ownership
of the shares. In addition, if you receive Social Security or certain railroad retirement benefits, you may be subject to U.S.
federal income tax on a portion of such benefits as a result of receiving investment income, including exempt-interest dividends
and other distributions paid by the Trust.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">If the Trust invests in certain pay-in-kind securities, zero
coupon securities, deferred interest securities or, in general, any other securities with original issue discount (or with market
discount if the Trust elects to include market discount in income currently), the Trust must accrue income on such investments
for each taxable year, which generally will be prior to the receipt of the corresponding cash payments. However, the Trust must
distribute to shareholders, at least annually, all or substantially all of its investment company taxable income (determined without
regard to the deduction for dividends paid) and net tax-exempt income, in each case including such accrued income, to qualify as
a RIC and to avoid federal income and excise taxes. Therefore, the Trust may have to dispose of its portfolio securities under
disadvantageous circumstances to generate cash, or may have to leverage itself by borrowing the cash, to satisfy these distribution
requirements.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may hold or acquire municipal obligations that are
market discount bonds. A market discount bond is a security acquired in the secondary market at a price below its redemption value
(or its adjusted issue price if it is also an original issue discount bond). Subject to the discussion below regarding Section
451 of the Code, (i) generally, any gain recognized on the disposition of, and any partial payment of principal on, a debt obligation
having market discount is treated as ordinary income to the extent the gain, or principal payment, does not exceed the &#8220;accrued
market discount&#8221; on such debt obligation, (ii) alternatively, the Trust may elect to accrue market discount currently, in
which case the Trust will be required to include the accrued market discount on such debt obligations in the Trust's income (as
ordinary income) and thus distribute it over the term of the debt obligation, even though payment of that amount is not received
until a later time, upon partial or full repayment or disposition of the debt obligation, and (iii) the rate at which the market
discount accrues, and thus is included in the Trust's income, will depend upon which of the permitted accrual methods the Trust
elects. The Trust reserves the right to revoke such an election at any time pursuant to applicable IRS procedures. Notwithstanding
the foregoing, Section 451 of the Code generally requires any accrual method taxpayer to take into account items of gross income
no later than the time at which such items are taken into account as revenue in the taxpayer's financial statements. However, the
Treasury Department has issued proposed regulations on which taxpayers may currently rely providing that Section 451 does not apply
to accrued market discount, subject to issuance of final regulations. If Section 451 were to apply to the accrual of market discount,
the Trust would be required to include in income any market discount as it takes the same into account on its financial statements.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may invest to a significant extent in debt obligations
that are in the lowest rating categories or are unrated, including debt obligations of issuers not currently paying interest or
who are in default. Investments in debt obligations that are at risk of or in default present special tax issues for the Trust.
Tax rules are not entirely clear about issues such as when the Trust may cease to accrue interest, original issue discount or market
discount, when and to what extent deductions may be taken for bad debts or worthless securities and how payments received on obligations
in default should be allocated between principal and income.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust&#8217;s investments in options, futures contracts,
hedging transactions, forward contracts (to the extent permitted) and certain other transactions will be subject to special tax
rules (including mark-to-market, constructive sale, straddle, wash sale, short sale and other rules), the effect of which may be
to accelerate income to the Trust, defer Trust losses, cause adjustments in the holding periods of Trust securities, convert capital
gain into ordinary income and convert short-term capital losses into long-term capital losses. These rules could therefore affect
the amount, timing and character of distributions to investors.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">As a result of entering into swap contracts, the Trust may make
or receive periodic net payments. The Trust may also make or receive a payment when a swap is terminated prior to maturity through
an assignment of the swap or other closing transaction. Periodic net payments will generally constitute ordinary income or deductions,
while termination of a swap will generally result in capital gain or loss (which will be a long-term capital gain or loss if the
Trust has been a party to a swap for more than one year). With respect to certain types of swaps, the Trust may be required to
currently recognize income or loss with respect to future payments on such swaps or may elect under certain circumstances to mark
such swaps to market annually for tax purposes as ordinary income or loss. The tax treatment of many types of credit default swaps
is uncertain.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The net investment income of certain U.S. individuals, estates
and trusts is subject to a 3.8% Medicare contribution tax. For individuals, the tax is on the lesser of the &#8220;net investment
income&#8221; and the excess of modified adjusted gross income over $200,000 (or $250,000 if married filing jointly). Net investment
income includes, among other things, interest, dividends (other than exempt-interest dividends), and gross income and capital gains
derived from passive activities and trading in securities or commodities. Net investment income is reduced by deductions &#8220;properly
allocable&#8221; to this income.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may invest in other securities the U.S. federal income
tax treatment of which is uncertain or subject to recharacterization by the IRS. To the extent the tax treatment of such securities
or their income differs from the tax treatment expected by the Trust, it could affect the timing or character of income recognized
by the Trust, requiring the Trust to purchase or sell securities, or otherwise change its portfolio, in order to comply with the
tax rules applicable to RICs under the Code.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust may be required to &#8220;backup&#8221; withhold,
for U.S. federal income tax purposes, a certain portion of all taxable distributions payable to shareholders who fail to provide
the Trust with their correct taxpayer identification number or to make required certifications, or if the shareholders have been
notified by the IRS that they are subject to backup withholding. Backup withholding is not an additional tax and any amounts withheld
may be credited against a shareholder&#8217;s U.S. federal income tax liability.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Under Treasury regulations, if a shareholder realizes a loss
on disposition of the Trust&#8217;s shares of at least $2 million in any single taxable year or $4 million in any combination of
taxable years for an individual shareholder or at least $10 million in any single taxable year or $20 million in any combination
of taxable years for a corporate shareholder, the shareholder must file with the IRS a disclosure statement on Form 8886. Direct
shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders
of a RIC are not excepted. The fact that a loss is reportable under these regulations does not affect the legal determination of
whether the taxpayer&#8217;s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability
of these regulations in light of their individual circumstances. Under certain circumstances, certain tax-exempt entities and their
managers may be subject to excise tax if they are parties to certain reportable transactions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In general, dividends (other than capital gain dividends and
exempt-interest dividends) paid to a shareholder that is not a &#8220;U.S. person&#8221; within the meaning of the Code (a &#8220;non-U.S.
shareholder&#8221;) are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Properly-designated dividends are generally exempt from U.S.
federal withholding tax where they (i) are paid in respect of the Trust&#8217;s &#8220;qualified net interest income&#8221; (generally,
the Trust&#8217;s U.S. source interest income, other than certain contingent interest and interest from obligations of a corporation
or partnership in which the Trust is at least a 10% shareholder (measured by total combined voting power for a corporation, and
measured by capital or profits interest for a partnership), reduced by expenses that are allocable to such income) or (ii) are
paid in respect of the Trust&#8217;s &#8220;qualified short-term capital gains&#8221; (generally, the excess of the Trust&#8217;s
net short-term capital gain over the Trust&#8217;s long-term capital loss for such taxable year). However, depending on its circumstances,
the Trust may designate all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified
short-term capital gains and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In
order to qualify for this exemption from withholding, a non-U.S. shareholder will need to comply with applicable certification
requirements relating to its non-U.S. status (including, in general, furnishing an applicable IRS Form W-8BEN or substitute Form).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">In the case of shares held through an intermediary, the intermediary
may withhold even if the Trust designates the payment as qualified net interest income or qualified short-term capital gain. Non-U.S.
shareholders should contact their intermediaries with respect to the application of these rules to their accounts.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Sections 1471-1474 of the Code and the U.S. Treasury and IRS
guidance issued thereunder (collectively, &#8220;FATCA&#8221;) generally require the Trust to obtain information sufficient to
identify the status of each of its shareholders under FATCA or under an applicable intergovernmental agreement (an &#8220;IGA&#8221;)
between the United States and a foreign government. If a shareholder fails to provide the requested information or otherwise fails
to comply with FATCA or an IGA, the Trust may be required to withhold under FATCA at a rate of 30% with respect to that shareholder
on ordinary dividends it pays. The IRS and Department of Treasury have issued proposed regulations providing that these withholding
rules will not be applicable to the gross proceeds of share redemptions or capital gain dividends the Trust pays. If a payment
by the Trust is subject to FATCA withholding, the Trust is required to withhold even if such payment would otherwise be exempt
from withholding under the rules applicable to foreign shareholders described above (e.g., interest-related dividends).</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Each prospective investor is urged to consult its tax adviser
regarding the applicability of FATCA and any other reporting requirements with respect to the prospective investor's own situation,
including investments through an intermediary.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Code, with respect to all of the foregoing matters and other
matters that may affect the Trust or the shareholders, is constantly subject to change by Congress. In recent years there have
been significant changes in the Code. It is not possible at this time to predict whether or to what extent any changes will be
made to the Code. Prospective investors should note that the Trust will not undertake to advise investors
of any legislative or other developments. Such investors should consult their own tax advisers regarding pending and proposed legislation
or other changes.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">The Trust is an organization of the type commonly known as a
&#8220;Massachusetts business trust.&#8221; 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, in coordination with the Trust&#8217;s By-laws, 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 has been advised by its counsel that the risk of any shareholder
incurring any liability for the obligations of the Trust is remote.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">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 or she would otherwise be subject by reason of willful misfeasance,
bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his or her office. Voting rights are
not cumulative, which means that the holders of more than 50% of the shares voting for the election of Trustees can elect 100%
of the Trustees and, in such event, the holders of the remaining less than 50% of the shares voting on the matter will not be able
to elect any Trustees.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">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&#8217;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.</P>

rating scales are forward-looking opinions of the relative credit risks of financial obligations issued by non-financial corporates,
financial institutions, structured finance vehicles, project finance vehicles, and public sector entities. Long-term ratings are
assigned to issuers or obligations with an original maturity of one year or more and reflect both the likelihood of a default or
impairment on contractual financial obligations and the expected financial loss suffered in the event of default or impairment.
Short-term ratings are assigned to obligations with an original maturity of thirteen months or less and reflect the likelihood

honor senior unsecured debt and debt like obligations. As such, Issuer Ratings incorporate any external support that is expected
to apply to all current and future issuance of senior unsecured financial obligations and contracts, such as explicit support stemming
from a guarantee of all senior unsecured financial obligations and contracts, and/or implicit support for issuers subject to joint
default analysis (e.g. banks and government-related issuers). Issuer Ratings do not incorporate support arrangements, such as guarantees,
that apply only to specific (but not to all) senior unsecured financial obligations and contracts.</P>

<P STYLE="font: bold 9pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">SHORT-TERM OBLIGATION RATINGS</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The global short-term &#8216;prime&#8217; rating scale is
applied to commercial paper issued by U.S. municipalities and nonprofits. These commercial paper programs may be backed by external
letters of credit or liquidity facilities, or by an issuer&#8217;s self-liquidity.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">For other short-term municipal obligations, Moody&#8217;s
uses one of two other short-term rating scales, the Municipal Investment Grade (MIG) and Variable Municipal Investment Grade (VMIG)
scales discussed below.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The MIG scale is used for U.S. municipal cash flow notes,
bond anticipation notes and certain other short-term obligations, which typically mature in three years or less. Under certain

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">In the case of variable rate demand obligations (VRDOs), a
two-component rating is assigned. The components are a long-term rating and a short-term demand obligation rating. The long-term
rating addresses the issuer&#8217;s ability to meet scheduled principal and interest payments. The short-term demand obligation
rating addresses the ability of the issuer or the liquidity provider to make payments associated with the purchase-price-upon demand
feature (&#8220;demand feature&#8221;) of the VRDO. The short-term demand obligation rating uses the VMIG scale. VMIG ratings with
liquidity support use as an input the short-term counterparty risk assessment of the support provider, or the long-term rating
of the underlying obligor in the absence of third party liquidity support. Transitions of VMIG ratings of demand obligations with
conditional liquidity support differ from transitions on the Prime scale to reflect the risk that external liquidity support will
terminate if the issuer&#8217;s long-term rating drops below investment grade.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>VMIG

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">ISSUE CREDIT RATINGS DEFINITIONS</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">An S&amp;P issue credit rating is a forward-looking opinion
about the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations,
or a specific financial program (including ratings on medium-term note programs and commercial paper programs). It takes into consideration
the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the
currency in which the obligation is denominated. The opinion reflects S&amp;P&#8217;s view of the obligor's capacity and willingness
to meet its financial commitments as they come due, and may assess terms, such as collateral security and subordination, which
could affect ultimate payment in the event of default.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Issue credit ratings can be either long-term or short-term.
Short-term issue credit ratings are generally assigned to those obligations considered short-term in the relevant market. Short-term
issue credit ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations.
Medium-term notes are assigned long-term ratings.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">LONG-TERM ISSUE CREDIT RATINGS:</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Issue credit ratings are based, in varying degrees, on S&amp;P&#8217;s
analysis of the following considerations:</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><FONT STYLE="font-family: Symbol">&middot;</FONT> Likelihood
of payment&#8212;capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the
terms of the obligation;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><FONT STYLE="font-family: Symbol">&middot;</FONT> Nature of and
provisions of the financial obligation and the promise that it is imputed; and</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><FONT STYLE="font-family: Symbol">&middot;</FONT> Protection
afforded by, and relative position of, the financial obligation in the event of bankruptcy, reorganization, or other arrangement
under the laws of bankruptcy and other laws affecting creditors' rights.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Issue ratings are an assessment of default risk, but may incorporate
an assessment of relative seniority or ultimate recovery in the event of default. Junior obligations are typically rated lower
than senior obligations, to reflect the lower priority in bankruptcy, as noted above. (Such differentiation may apply when an entity
has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.)</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>AAA:</B></FONT>
An obligation rated &#8216;AAA&#8217; has the highest rating assigned by S&amp;P. The obligor&#8217;s capacity to meet its financial

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>AA:</B></FONT>
An obligation rated &#8216;AA&#8217; differs from the highest-rated obligors only to a small degree. The obligor&#8217;s capacity

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>A:</B></FONT>
An obligation rated &#8216;A&#8217; is somewhat more susceptible to the adverse effects of changes in circumstances and economic
conditions than obligations in higher-rated categories. However, the obligor&#8217;s capacity to meet its financial commitments
on the obligation is still strong.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>BBB:</B></FONT>
An obligation rated &#8216;BBB&#8217; exhibits adequate protection parameters. However, adverse economic conditions or changing

the least degree of speculation and &#8216;C&#8217; the highest. While such obligations will likely have some quality and protective
characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>BB:</B></FONT>
An obligation rated &#8216;BB&#8217; is less vulnerable to non-payment than other speculative issues. However, it faces major ongoing
uncertainties or exposure to adverse business, financial, or economic conditions that could lead to the obligor&#8217;s inadequate

An obligation rated 'D' is in default or in breach of an imputed promise. For non-hybrid capital instruments, the 'D' rating category

five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days.
The 'D' rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on
an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation's rating is lowered to 'D' if
it is subject to a distressed exchange offer.</P>

and economic conditions for the obligor to meet its financial commitments on the obligation.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>D:</B></FONT>
A short-term obligation rated 'D' is in default or in breach of an imputed promise. For non-hybrid capital instruments, the 'D'
rating category is used when payments on an obligation are not made on the date due, unless S&amp;P believes that such payments
will be made within any stated grace period. However, any stated grace period longer than five business days will be treated as
five business days. The 'D' rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action
and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. A rating on an obligation
is lowered to 'D' if it is subject to a distressed exchange offer.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">S&amp;P&#8217;s issuer credit rating is a forward-looking opinion
about an obligor's overall creditworthiness. This opinion focuses on the obligor's capacity and willingness to meet its financial
commitments as they come due. It does not apply to any specific financial obligation, as it does not take into account the nature
of and provisions of the obligation, its standing in bankruptcy or liquidation, statutory preferences, or the legality and enforceability
of the obligation.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Sovereign credit ratings are forms of issuer credit ratings.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Issuer credit ratings can be either long-term or short-term.</P>

analysis will review the following considerations: Amortization schedule--the larger the final maturity relative to other maturities,
the more likely it will be treated as a note; and Source of payment--the more dependent the issue is on the market for its refinancing,

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">S&amp;P Insurer Financial Strength Ratings</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">An S&amp;P insurer financial strength rating is a forward-looking
opinion about the financial security characteristics of an insurance organization with respect to its ability to pay under its
insurance policies and contracts in accordance with their terms. Insurer financial strength ratings are also assigned to health
maintenance organizations and similar health plans with respect to their ability to pay under their policies and contracts in accordance
with their terms.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">This opinion is not specific to any particular policy or contract,
nor does it address the suitability of a particular policy or contract for a specific purpose or purchaser. Furthermore, the opinion
does not take into account deductibles, surrender or cancellation penalties, timeliness of payment, nor the likelihood of the use
of a defense such as fraud to deny claims.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Insurer financial strength ratings do not refer to an organization's
ability to meet nonpolicy (i.e., debt) obligations. Assignment of ratings to debt issued by insurers or to debt issues that are
fully or partially supported by insurance policies, contracts, or guarantees is a separate process from the determination of insurer
financial strength ratings, and it follows procedures consistent with those used to assign an issue credit rating. An insurer financial
strength rating is not a recommendation to purchase or discontinue any policy or contract issued by an insurer.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Long-Term Insurer Financial Strength Ratings</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Category Definition</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">AAA</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">An insurer rated 'AAA' has extremely strong financial security
characteristics. 'AAA' is the highest insurer financial strength rating assigned by S&amp;P.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">AA</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">An insurer rated 'AA' has very strong financial security characteristics,
differing only slightly from those rated higher.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">A</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">An insurer rated 'A' has strong financial security characteristics,
but is somewhat more likely to be affected by adverse business conditions than are insurers with higher ratings.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">BBB</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">An insurer rated 'BBB' has good financial security characteristics,
but is more likely to be affected by adverse business conditions than are higher-rated insurers.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">BB, B, CCC and CC</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">An insurer rated 'BB' or lower is regarded as having vulnerable
characteristics that may outweigh its strengths. 'BB' indicates the least degree of vulnerability within the range and 'CC' the
highest.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">BB</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">An insurer rated 'BB' has marginal financial security characteristics.
Positive attributes exist, but adverse business conditions could lead to insufficient ability to meet financial commitments.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">B</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">An insurer rated 'B' has weak financial security characteristics.
Adverse business conditions will likely impair its ability to meet financial commitments.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">CCC</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">An insurer rated 'CCC' has very weak financial security characteristics,
and is dependent on favorable business conditions to meet financial commitments.</P>

and is likely not to meet some of its financial commitments.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">SD or D</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">An insurer rated 'SD' (selective default) or 'D' is in default
on one or more of its insurance policy obligations. The 'D' rating also will be used upon the filing of a bankruptcy petition or
the taking of similar action if payments on a policy obligation are at risk. A 'D' rating is assigned when S&amp;P believes that
the default will be a general default and that the obligor will fail to pay substantially all of its obligations in full in accordance
with the policy terms. An 'SD' rating is assigned when S&amp;P believes that the insurer has selectively defaulted on a specific
class of policies but it will continue to meet its payment obligations on other classes of obligations. A selective default includes
the completion of a distressed exchange offer. Claim denials due to lack of coverage or other legally permitted defenses are not
considered defaults.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">NR: <FONT STYLE="font-weight: normal">Indicates that

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0"><FONT STYLE="font-family: Arial, Helvetica, Sans-Serif"><B>Plus
(+) or Minus (-):</B></FONT> The ratings from &#8216;AA&#8217; to&#8217; CCC&#8217; may be modified by the addition of a plus (+)
or minus (-) sign to show relative standing within the major rating categories.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">Fitch Insurer Financial Strength Rating</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The Insurer Financial Strength (IFS) Rating provides an assessment
of the financial strength of an insurance organization. The IFS Rating is assigned to the insurance company's policyholder obligations,
including assumed reinsurance obligations and contract holder obligations, such as guaranteed investment contracts. The IFS Rating
reflects both the ability of the insurer to meet these obligations on a timely basis, and expected recoveries received by claimants
in the event the insurer stops making payments or payments are interrupted, due to either the failure of the insurer or some form
of regulatory intervention. In the context of the IFS Rating, the timeliness of payments is considered relative to both contract
and/or policy terms but also recognizes the possibility of reasonable delays caused by circumstances common to the insurance industry,
including claims reviews, fraud investigations and coverage disputes.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The IFS Rating does not encompass policyholder obligations residing
in separate accounts, unit-linked products or segregated funds, for which the policyholder bears investment or other risks. However,
any guarantees provided to the policyholder with respect to such obligations are included in the IFS Rating.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Expected recoveries are based on the agency's assessments of
the sufficiency of an insurance company's assets to fund policyholder obligations, in a scenario in which payments have ceased
or been interrupted. Accordingly, expected recoveries exclude the impact of recoveries obtained from any government sponsored guaranty
or policyholder protection funds. Expected recoveries also exclude the impact of collateralization or security, such as letters
of credit or trusteed assets, supporting select reinsurance obligations.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">IFS Ratings can be assigned to insurance and reinsurance companies
in any insurance sector, including the life &amp; annuity, non-life, property/casualty, health, mortgage, financial guaranty, residual
value and title insurance sectors, as well as to managed care companies such as health maintenance organizations.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The IFS Rating uses the same symbols used by the agency for its
International and National credit ratings of long-term or short-term debt issues. However, the definitions associated with the
ratings reflect the unique aspects of the IFS Rating within an insurance industry context.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Obligations for which a payment interruption has occurred due
to either the insolvency or failure of the insurer or some form of regulatory intervention will generally be rated between 'B'
and 'C' on the Long-Term IFS Rating scales (both International and National). International Short-Term IFS Ratings assigned under
the same circumstances will align with the insurer's International Long-Term IFS Ratings.</P>

a copy of its proxy voting policies and procedures (&#8220;Adviser Procedures&#8221;) and all Fund proxies will be voted in accordance
with the Adviser Procedures, provided that in the event a material conflict of interest arises with respect to a proxy to be voted
for the Fund (as described in Section IV below) the Adviser shall follow the process for voting such proxy as described in Section
IV below.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The Adviser is required to report any material change to the

Act of 1940, as amended (the &#8220;1940 Act&#8221;), the Fund is required to file Form N-PX no later than August 31st of each

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The Board expects the Adviser, as a fiduciary to the Fund it
manages, to put the interests of the Fund and its shareholders above those of the Adviser. When required to vote a proxy for the
Fund, the Adviser may have material business relationships with the issuer soliciting the proxy that could give rise to a potential
material conflict of interest for the Adviser.<FONT STYLE="font-family: Arial Narrow, Helvetica, Sans-Serif; font-size: 9pt"><SUP>2</SUP></FONT>
In the event such a material conflict of interest arises, the Adviser, to the extent it is aware or reasonably should have been
aware of the material conflict, will refrain from voting any proxies related to companies giving rise to such material conflict
until it notifies and consults with the appropriate Board, or any committee, sub-committee or group of Independent Trustees identified
by the Board (as long as such committee, sub-committee or group contains at least two or more Independent Trustees) (the &#8220;Board
Members&#8221;), concerning the material conflict.<FONT STYLE="font-family: Arial Narrow, Helvetica, Sans-Serif; font-size: 9pt"><SUP>3</SUP></FONT>
For ease of communicating with the Board Members, the Adviser is required to provide the foregoing notice to the Fund&#8217;s Chief
Legal Officer who will then notify and facilitate a consultation with the Board Members.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Eaton Vance Management, Boston Management and Research, Eaton
Vance Investment Counsel, Eaton Vance Management (International) Limited, Eaton Vance Advisers International Ltd. and Eaton Vance
Trust Company (each an &#8220;Adviser&#8221; and collectively the &#8220;Advisers&#8221;) have each adopted and implemented policies
and procedures that each Adviser believes are reasonably designed to ensure that proxies are voted in the best interest of clients,
in accordance with its fiduciary duties and, to the extent applicable, Rule 206(4)-6 under the Investment Advisers Act of 1940,
as amended. The Advisers&#8217; authority to vote the proxies of their clients is established by their advisory contracts or similar
documentation. These proxy policies and procedures are intended to reflect current requirements applicable to investment advisers
registered with the U.S. Securities and Exchange Commission (&#8220;SEC&#8221;). These procedures may change from time to time.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">II. Overview</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Each Adviser manages its clients&#8217; assets with the overriding
goal of seeking to provide the greatest possible return to such clients consistent with governing laws and the investment policies
of each client. In pursuing that goal, each Adviser seeks to exercise its clients&#8217; rights as shareholders of voting securities
to support sound corporate governance of the companies issuing those securities with the principle aim of maintaining or enhancing
the companies&#8217; economic value.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">The exercise of shareholder rights is generally done by casting
votes by proxy at shareholder meetings on matters submitted to shareholders for approval (for example, the election of directors
or the approval of a company&#8217;s stock option plans for directors, officers or employees). Each Adviser has established guidelines
(&#8220;Guidelines&#8221;) as described below and generally will utilize such Guidelines in voting proxies on behalf of its clients.
The Guidelines are largely based on those developed by the Agent (defined below) but also reflect input from the Global Proxy Group
(defined below) and other Adviser investment professionals and are believed to be consistent with the views of the Adviser on the
various types of proxy proposals. These Guidelines are designed to promote accountability of a company&#8217;s management and board
of directors to its shareholders and to align the interests of management with those of shareholders. The Guidelines provide a
framework for analysis and decision making but do not address all potential issues.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 6pt 0">Except as noted below, each Adviser will vote any proxies received
by a client for which it has sole investment discretion through a third-party proxy voting service (&#8220;Agent&#8221;) in accordance
with the Guidelines in a manner that is reasonably designed to eliminate any potential conflicts of interest, as described more
fully below. The Agent is currently Institutional Shareholder Services Inc. Where applicable, proxies will be voted in accordance
with client-specific guidelines or, in the case of an Eaton Vance Fund that is sub-advised, pursuant to the sub-adviser&#8217;s
proxy voting policies and procedures. Although an Adviser retains the services of the Agent for research and voting recommendations,
the Adviser remains responsible for proxy voting decisions.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0">III. Roles and Responsibilities</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">A. Proxy Administrator</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">The Proxy Administrator and/or her designee coordinate
the consideration of proxies referred back to the Adviser by the Agent, and otherwise administers these Procedures. In the Proxy
Administrator&#8217;s absence, another employee of the Adviser may perform the Proxy Administrator&#8217;s responsibilities as
deemed appropriate by the Global Proxy Group. The Proxy Administrator also may designate another employee to perform certain of
the Proxy Administrator&#8217;s duties hereunder, subject to the oversight of the Proxy Administrator.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">The Agent is responsible for coordinating with the
clients&#8217; custodians and the Advisers to ensure that all proxy materials received by the custodians relating to the portfolio
securities are processed in a timely fashion. Each Adviser shall instruct the custodian for its clients to deliver proxy ballots
and related materials to the Agent. The Agent shall vote and/or refer all proxies in accordance with the Guidelines. The Agent
shall retain a record of all proxy votes handled by the Agent. With respect to each Eaton Vance Fund memorialized therein, such
record must reflect all of the information required to be disclosed in the Fund&#8217;s Form N-PX pursuant to Rule 30b1-4 under
the Investment Company Act of 1940, to the extent applicable. In addition, the Agent is responsible for maintaining copies of all
proxy statements received by issuers and to promptly provide such materials to an Adviser upon request.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">Subject to the oversight of the Advisers, the Agent
shall establish and maintain adequate internal controls and policies in connection with the provision of proxy voting services
to the Advisers, including methods to reasonably ensure that its analysis and recommendations are not influenced by a conflict
of interest, and shall disclose such controls and policies to the Advisers when and as provided for herein. Unless otherwise specified,
references herein to recommendations of the Agent shall refer to those in which no conflict of interest has been identified. The
Advisers are responsible for the ongoing oversight of the Agent as contemplated by SEC Staff Legal Bulletin No. 20 (June 30, 2014)
and interpretive guidance issued by the SEC in August 2019 regarding proxy voting responsibilities of investment advisers (Release
Nos. IA-5325 and IC-33605). Such oversight currently may include one or more of the following and may change from time to time:</P>

at least annually and, in connection with proxies to be voted on behalf of the Eaton Vance Funds, the Adviser will submit amendments
to the Guidelines to the Fund Boards each year for approval.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">With respect to the types of proxy proposals listed
below, the Guidelines will generally provide as follows:</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">1. Proposals Regarding Mergers and Corporate
Restructurings/Disposition of Assets/Termination/Liquidation and Mergers</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">The Agent shall be directed to refer proxy proposals

Defenses</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">As a general matter, the Advisers will normally vote
against anti-takeover measures and other proposals designed to limit the ability of shareholders to act on possible transactions
(except in the case of closed-end management investment companies).</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">3. Proposals Regarding Proxy Contests</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">The Agent shall be directed to refer contested proxy
proposals accompanied by its written analysis and voting recommendation to the Proxy Administrator and/or her designee.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">Interpretation and application of the Guidelines is
not intended to supersede any law, regulation, binding agreement or other legal requirement to which an issuer or the Adviser may
be or become subject. The Guidelines generally relate to the types of proposals that are most frequently presented in proxy statements
to shareholders. In certain circumstances, an Adviser may determine to vote contrary to the Guidelines subject to the voting procedures
set forth below.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">B. Voting Procedures</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">Except as noted in Section V below, the Proxy Administrator
and/or her designee shall instruct the Agent to vote proxies as follows:</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">1. Vote in Accordance with Guidelines</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">If the Guidelines prescribe the manner in which the
proxy is to be voted, the Agent shall vote in accordance with the Guidelines, which for certain types of proposals, are recommendations
of the Agent made on a case-by-case basis.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">2. Seek Guidance for a Referred Item or a Proposal
for which there is No Guideline</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">If (i) the Guidelines state that the proxy shall be
referred to the Adviser to determine the manner in which it should be voted or (ii) a proxy is received for a proposal for which
there is no Guideline, the Proxy Administrator and/or her designee shall consult with the analyst(s) covering the company subject
to the proxy proposal and shall instruct the Agent to vote in accordance with the determination of the analyst. The Proxy Administrator
and/or her designee will maintain a record of all proxy proposals that are referred by the Agent, as well as all applicable recommendations,
analysis and research received and the resolution of the matter. Where more than one analyst covers a particular company and the
recommendations of such analysts for voting a proposal subject to this Section IV.B.2 conflict, the Global Proxy Group shall review
such recommendations and any other available information related to the proposal and determine the manner in which it should be
voted, which may result in different recommendations for clients (including Funds).</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">3. Votes Contrary to the Guidelines or Where
Agent is Conflicted</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">In the event an analyst with respect to
companies within his or her coverage area may recommend a vote contrary to the Guidelines, the Proxy Administrator and/or her
designee will provide the Global Proxy Group with the Agent&#8217;s recommendation for the Proposal along with any other
relevant materials, including a description of the basis for the analyst&#8217;s recommendation via email and the Proxy
Administrator and/or designee will then instruct the Agent to vote the proxy in the manner determined by the Global Proxy
Group. Should the vote <FONT STYLE="letter-spacing: 0.1pt">by</FONT> the <FONT STYLE="letter-spacing: -0.05pt">Global</FONT> <FONT STYLE="letter-spacing: 0.05pt">Proxy</FONT>

be <FONT STYLE="letter-spacing: -0.05pt">voted. </FONT>The Adviser will provide a report to the Boards of Trustees of the
Eaton Vance Funds reflecting any votes cast on behalf of
the Eaton Vance Funds contrary to the Guidelines, and shall do so quarterly. A similar process will be followed if the Agent has
a conflict of interest with respect to a proxy as described in Section VI.B.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">It shall generally be the policy of the Advisers to
take no action on a proxy for which no client holds a position or otherwise maintains an economic interest in the relevant security
at the time the vote is to be cast. In addition, the Advisers may determine not to vote (i) if the economic effect on shareholders'
interests or the value of the portfolio holding is indeterminable or insignificant (<I>e.g.,</I> proxies in connection with securities
no longer held in the portfolio of a client or proxies being considered on behalf of a client that is no longer in existence);
(ii) if the cost of voting a proxy outweighs the benefits (<I>e.g.,</I> certain international proxies, particularly in cases in
which share blocking practices may impose trading restrictions on the relevant portfolio security); (iii) in markets in which shareholders'
rights are limited; or (iv) the Adviser is unable to access or access timely ballots or other proxy information. Non-Votes may
also result in certain cases in which the Agent's recommendation has been deemed to be conflicted, as provided for herein.</P>

<P STYLE="font: bold 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">C. Securities on Loan</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 3pt 0 3pt 0.25in">When a fund client participates in the lending of
its securities and the securities are on loan at the record date for a shareholder meeting, proxies related to such securities
generally will not be forwarded to the relevant Adviser by the fund&#8217;s custodian and therefore will not be voted. In the event
that the Adviser determines that the matters involved would have a material effect on the applicable fund&#8217;s investment in
the loaned securities, the Adviser will make reasonable efforts to terminate the loan in time to be able to cast such vote or exercise
such consent. The Adviser shall instruct the fund&#8217;s security lending agent to refrain from lending the full position of any
security held by a fund to ensure that the Adviser receives notice of proxy proposals impacting the loaned security.</P>
