following hypothetical example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds.
It assumes that you invest $10,000 in the fund for the time periods indicated and then, except as indicated, redeem all your shares at
the end of those periods. It assumes a 5% return on your investment each year and that the fund&#x2019;s operating expenses remain the
same. Your actual costs may be higher or lower.&lt;/p&gt;

investments. Tax-exempt investments are issued by or for states, territories or possessions of the United States or by their political
subdivisions, agencies, authorities or other government entities, and the income from these investments is exempt from both federal and
Massachusetts personal income tax. This investment policy cannot be changed without the approval of the fund&#x2019;s shareholders. We
may consider, among other factors, credit, interest rate and prepayment risks, as well as general market conditions, when deciding whether
to buy or sell investments.&lt;/p&gt;

&lt;p style="font: 300 10px/1.26 Arial, Helvetica, Sans-Serif; margin: 0 0 6px 42px; color: #000000; text-align: left"&gt;The value of investments
in the fund&#x2019;s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including general economic,
political or financial market conditions, investor sentiment and market perceptions, government actions, geopolitical events or changes,
and factors related to a specific issuer, geography, industry or sector. These and other factors may lead to increased volatility and
reduced liquidity in the fund&#x2019;s portfolio holdings.&lt;/p&gt;

&lt;p style="font: 300 10px/1.26 Arial, Helvetica, Sans-Serif; margin: 0 0 6px 42px; color: #000000; text-align: left"&gt;&lt;span style="-sec-ix-redline: true"&gt;The
risks associated with bond investments include interest rate risk, which is the risk that the value of the fund&#x2019;s investments is
likely to fall if interest rates rise. Bond investments also are subject to credit risk, which is the risk that the issuers of the fund&#x2019;s
investments may default on payment of interest or principal. Bond investments may be more susceptible to downgrades or defaults during
economic downturns or other periods of economic stress. Interest rate risk is generally greater for longer-term bonds, and credit risk
is generally greater for below-investment-grade bonds, which can be more sensitive to changes in markets, credit conditions, and interest
rates. Since the fund invests in tax-exempt bonds, which, to be treated as tax-exempt under the Internal Revenue Code, may be issued only
by limited types of issuers for limited types of projects, the fund&#x2019;s investments may be focused in certain market segments. Consequently,
the fund may be more vulnerable to fluctuations in the values of the securities it holds than a fund that invests more broadly. The fund&#x2019;s
performance will be closely tied to the economic and political conditions in Massachusetts, and can be more volatile than the performance
of a more geographically diversified fund. To the extent the fund invests in securities of issuers located outside of Massachusetts, the
fund may also be exposed to the risks affecting other states. Interest the fund receives might be taxable.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 300 10px/1.26 Arial, Helvetica, Sans-Serif; margin: 0 0 6px 42px; color: #000000; text-align: left"&gt;&lt;span style="-sec-ix-redline: true"&gt;There
is no guarantee that the investment techniques, analyses, or judgements that we apply in making investment decisions for the fund will
produce the intended outcome or that the investments we select for the fund will perform as well as the other securities that were not
selected for the fund. We, or the fund&#x2019;s other service providers, may experience disruptions or operating errors that could negatively
impact the fund.&lt;/span&gt;&lt;/p&gt;

following hypothetical example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds.
It assumes that you invest $10,000 in the fund for the time periods indicated and then, except as indicated, redeem all your shares at
the end of those periods. It assumes a 5% return on your investment each year and that the fund&#x2019;s operating expenses remain the
same. Your actual costs may be higher or lower.&lt;/p&gt;

Tax-exempt investments are issued by or for states, territories or possessions of the United States or by their political subdivisions,
agencies, authorities or other government entities, and the income from these investments is exempt from both federal and Minnesota personal
income tax. This investment policy cannot be changed without the approval of the fund&#x2019;s shareholders. We may consider, among other
factors, credit, interest rate and prepayment risks, as well as general market conditions, when deciding whether to buy or sell investments.&lt;/p&gt;

in the fund&#x2019;s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including general economic,
political or financial market conditions, investor sentiment and market perceptions, government actions, geopolitical events or changes,
and factors related to a specific issuer, geography, industry or sector. These and other factors may lead to increased volatility and
reduced liquidity in the fund&#x2019;s portfolio holdings.&lt;/p&gt;

&lt;p style="font: 300 10px/1.26 Arial, Helvetica, Sans-Serif; margin: 0 0 6px 42px; color: #000000; text-align: left"&gt;&lt;span style="-sec-ix-redline: true"&gt;The
risks associated with bond investments include interest rate risk, which is the risk that the value of the fund&#x2019;s investments is
likely to fall if interest rates rise. Bond investments also are subject to credit risk, which is the risk that the issuers of the fund&#x2019;s
investments may default on payment of interest or principal. Bond investments may be more susceptible to downgrades or defaults during
economic downturns or other periods of economic stress. Interest rate risk is generally greater for longer-term bonds, and credit risk
is generally greater for below-investment-grade bonds, which can be more sensitive to changes in markets, credit conditions, and interest
rates. Since the fund invests in tax-exempt bonds, which, to be treated as tax-exempt under the Internal Revenue Code, may be issued only
by limited types of issuers for limited types of projects, the fund&#x2019;s investments may be focused in certain market segments. Consequently,
the fund may be more vulnerable to fluctuations in the values of the securities it holds than a fund that invests more broadly. The fund&#x2019;s
performance will be closely tied to the economic and political conditions in Minnesota, and can be more volatile than the performance
of a more geographically diversified fund. To the extent the fund invests in securities of issuers located outside of Minnesota, the fund
may also be exposed to the risks affecting other states. Interest the fund receives might be taxable.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 300 10px/1.26 Arial, Helvetica, Sans-Serif; margin: 0 0 6px 42px; color: #000000; text-align: left"&gt;&lt;span style="-sec-ix-redline: true"&gt;There
is no guarantee that the investment techniques, analyses, or judgements that we apply in making investment decisions for the fund will
produce the intended outcome or that the investments we select for the fund will perform as well as the other securities that were not
selected for the fund. We, or the fund&#x2019;s other service providers, may experience disruptions or operating errors that could negatively
impact the fund.&lt;/span&gt;&lt;/p&gt;

Tax-exempt investments are issued by or for states, territories or possessions of the United States or by their political subdivisions,

in the fund&#x2019;s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including general economic,
political or financial market conditions, investor sentiment and market perceptions, government actions, geopolitical events or changes,
and factors related to a specific issuer, geography, industry or sector. These and other factors may lead to increased volatility and
reduced liquidity in the fund&#x2019;s portfolio holdings.&lt;/p&gt;

&lt;p style="font: 300 10px/1.26 Arial, Helvetica, Sans-Serif; margin: 0 0 6px 42px; color: #000000; text-align: left"&gt;&lt;span style="-sec-ix-redline: true"&gt;The
risks associated with bond investments include interest rate risk, which is the risk that the value of the fund&#x2019;s investments is
likely to fall if interest rates rise. Bond investments also are subject to credit risk, which is the risk that the issuers of the fund&#x2019;s
investments may default on payment of interest or principal. Bond investments may be more susceptible to downgrades or defaults during
economic downturns or other periods of economic stress. Interest rate risk is generally greater for longer-term bonds, and credit risk
is generally greater for below-investment-grade bonds, which can be more sensitive to changes in markets, credit conditions, and interest
rates. Since the fund invests in tax-exempt bonds, which, to be treated as tax-exempt under the Internal Revenue Code, may be issued only
by limited types of issuers for limited types of projects, the fund&#x2019;s investments may be focused in certain market segments. Consequently,
the fund may be more vulnerable to fluctuations in the values of the securities it holds than a fund that invests more broadly. The fund&#x2019;s
performance will be closely tied to the economic and political conditions in New Jersey, and can be more volatile than the performance
of a more geographically diversified fund. To the extent the fund invests in securities of issuers located outside of New Jersey, the
fund may also be exposed to the risks affecting other states. Interest the fund receives might be taxable.&lt;/span&gt;&lt;/p&gt;

is no guarantee that the investment techniques, analyses, or judgements that we apply in making investment decisions for the fund will
produce the intended outcome or that the investments we select for the fund will perform as well as the other securities that were not
selected for the fund. We, or the fund's other service providers, may experience disruptions or operating errors that could negatively
impact the fund.&lt;/span&gt;&lt;/p&gt;

following hypothetical example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds.
It assumes that you invest $10,000 in the fund for the time periods indicated and then, except as indicated, redeem all your shares at
the end of those periods. It assumes a 5% return on your investment each year and that the fund&#x2019;s operating expenses remain the
same. Your actual costs may be higher or lower.&lt;/p&gt;

Tax-exempt investments are issued by or for states, territories or possessions of the United States or by their political subdivisions,

in the fund&#x2019;s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including general economic,
political or financial market conditions, investor sentiment and market perceptions, government actions, geopolitical events or changes,
and factors related to a specific issuer, geography, industry or sector. These and other factors may lead to increased volatility and
reduced liquidity in the fund&#x2019;s portfolio holdings.&lt;/p&gt;

risks associated with bond investments include interest rate risk, which is the risk that the value of the fund&#x2019;s investments is
likely to fall if interest rates rise. Bond investments also are subject to credit risk, which is the risk that the issuers of the fund&#x2019;s
investments may default on payment of interest or principal. Bond investments may be more susceptible to downgrades or defaults during
economic downturns or other periods of economic stress. Interest rate risk is generally greater for longer-term bonds, and credit risk
is generally greater for below-investment-grade bonds, which can be more sensitive to changes in markets, credit conditions, and interest
rates. Since the fund invests in tax-exempt bonds, which, to be treated as tax-exempt under the Internal Revenue Code, may be issued only
by limited types of issuers for limited types of projects, the fund&#x2019;s investments may be focused in certain market segments. Consequently,
the fund may be more vulnerable to fluctuations in the values of the securities it holds than a fund that invests more broadly. The fund&#x2019;s
performance will be closely tied to the economic and political conditions in Ohio, and can be more volatile than the performance of a
more geographically diversified fund. To the extent the fund invests in securities of issuers located outside of Ohio, the fund may also
be exposed to the risks affecting other states. Interest the fund receives might be taxable.&lt;/span&gt;&lt;/p&gt;

is no guarantee that the investment techniques, analyses, or judgements that we apply in making investment decisions for the fund will
produce the intended outcome or that the investments we select for the fund will perform as well as the other securities that were not
selected for the fund. We, or the fund&#x2019;s other service providers, may experience disruptions or operating errors that could negatively
impact the fund.&lt;/span&gt;&lt;/p&gt;

following hypothetical example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds.
It assumes that you invest $10,000 in the fund for the time periods indicated and then, except as indicated, redeem all your shares at
the end of those periods. It assumes a 5% return on your investment each year and that the fund&#x2019;s operating expenses remain the
same. Your actual costs may be higher or lower.&lt;/p&gt;

Tax-exempt investments are issued by or for states, territories or possessions of the United States or by their political subdivisions,

in the fund&#x2019;s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including general economic,
political or financial market conditions, investor sentiment and market perceptions, government actions, geopolitical events or changes,
and factors related to a specific issuer, geography, industry or sector. These and other factors may lead to increased volatility and
reduced liquidity in the fund&#x2019;s portfolio holdings.&lt;/p&gt;

&lt;p style="font: 300 10px/1.26 Arial, Helvetica, Sans-Serif; margin: 0 0 6px 42px; color: #000000; text-align: left"&gt;&lt;span style="-sec-ix-redline: true"&gt;The
risks associated with bond investments include interest rate risk, which is the risk that the value of the fund&#x2019;s investments is
likely to fall if interest rates rise. Bond investments also are subject to credit risk, which is the risk that the issuers of the fund&#x2019;s
investments may default on payment of interest or principal. Bond investments may be more susceptible to downgrades or defaults during
economic downturns or other periods of economic stress. Interest rate risk is generally greater for longer-term bonds, and credit risk
is generally greater for below-investment-grade bonds, which can be more sensitive to changes in markets, credit conditions, and interest
rates. Since the fund invests in tax-exempt bonds, which, to be treated as tax-exempt under the Internal Revenue Code, may be issued only
by limited types of issuers for limited types of projects, the fund&#x2019;s investments may be focused in certain market segments. Consequently,
the fund may be more vulnerable to fluctuations in the values of the securities it holds than a fund that invests more broadly. The fund&#x2019;s
performance will be closely tied to the economic and political conditions in Pennsylvania, and can be more volatile than the performance
of a more geographically diversified fund. To the extent the fund invests in securities of issuers located outside of Pennsylvania, the
fund may also be exposed to the risks affecting other states. Interest the fund receives might be taxable.&lt;/span&gt;&lt;/p&gt;

is no guarantee that the investment techniques, analyses, or judgements that we apply in making investment decisions for the fund will
produce the intended outcome or that the investments we select for the fund will perform as well as the other securities that were not
selected for the fund. We, or the fund&#x2019;s other service providers, may experience disruptions or operating errors that could negatively
impact the fund.&lt;/span&gt;&lt;/p&gt;
