<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The discussion below describes the portfolio managers&#146; compensation as of July&nbsp;31, 2022. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Advisor&#146;s financial arrangements with its portfolio managers, its competitive compensation and its career path emphasis at all levels reflect the
value senior management places on key resources. Compensation may include a variety of components and may vary from year to year based on a number of factors. The principal components of compensation include a base salary, a performance-based
discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by the Advisor. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Base Compensation.</B>&nbsp;Generally, portfolio managers receive base compensation based on their position with the firm. </P>

<p style="margin-top:1em; margin-bottom:0em; page-break-before:always">
<HR SIZE="3" style="COLOR:#999999" WIDTH="100%" ALIGN="CENTER">
 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Discretionary Incentive Compensation. </B>Discretionary incentive compensation is a function of several
components: the performance of BlackRock, Inc., the performance of the portfolio manager&#146;s group within BlackRock, the investment performance, including risk-adjusted returns, of the firm&#146;s assets under management or supervision by that
portfolio manager relative to predetermined benchmarks, and the individual&#146;s performance and contribution to the overall performance of these portfolios and BlackRock. In most cases, these benchmarks are the same as the benchmark or benchmarks
against which the performance of the Trust or other accounts managed by the portfolio managers are measured. Among other things, BlackRock&#146;s Chief Investment Officers make a subjective determination with respect to each portfolio manager&#146;s
compensation based on the performance of the Trust and other accounts managed by each portfolio manager relative to the various benchmarks. Performance of fixed income funds is measured on <FONT STYLE="white-space:nowrap"><FONT
STYLE="white-space:nowrap">a&nbsp;pre-tax&nbsp;and/or&nbsp;after-tax&nbsp;basis</FONT></FONT> over various time periods
<FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">including&nbsp;1-,&nbsp;3-&nbsp;and&nbsp;5-&nbsp;year</FONT></FONT></FONT> periods, as applicable. With respect to these portfolio managers, such
benchmarks for the Trust and other accounts are: a combination of market-based indices (e.g., Bloomberg Municipal Bond Index), certain customized indices and certain fund industry peer groups. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Distribution of Discretionary Incentive Compensation.</B>&nbsp;Discretionary incentive compensation is distributed to portfolio managers in a combination
of cash, deferred BlackRock, Inc. stock awards, and/or deferred cash awards that notionally track the return of certain BlackRock investment products. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Portfolio managers receive their annual discretionary incentive compensation in the form of cash. Portfolio managers whose total compensation is above a
specified threshold also receive deferred BlackRock, Inc. stock awards annually as part of their discretionary incentive compensation. Paying a portion of discretionary incentive compensation in the form of deferred BlackRock, Inc. stock puts
compensation earned by a portfolio manager for a given year &#147;at risk&#148; based on BlackRock&#146;s ability to sustain and improve its performance over future periods. In some cases, additional deferred BlackRock, Inc. stock may be granted to
certain key employees as part of a long-term incentive award to aid in retention, align interests with long-term shareholders and motivate performance. Deferred BlackRock, Inc. stock awards are generally granted in the form of BlackRock, Inc.
restricted stock units that vest pursuant to the terms of the applicable plan and, once vested, settle in BlackRock, Inc. common stock. The portfolio managers of this Trust have deferred BlackRock, Inc. stock awards. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">For certain portfolio managers, a portion of the discretionary incentive compensation is also distributed in the form of deferred cash awards that notionally
track the returns of select BlackRock investment products they manage, which provides direct alignment of portfolio manager discretionary incentive compensation with investment product results. Deferred cash awards vest ratably over a number of
years and, once vested, settle in the form of cash. Only portfolio managers who manage specified products and whose total compensation is above a specified threshold are eligible to participate in the deferred cash award program. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Other Compensation Benefits.</B>&nbsp;In addition to base salary and discretionary incentive compensation, portfolio managers may be eligible to receive or
participate in one or more of the following: </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Incentive Savings Plans&#151;</I>BlackRock, Inc. has created a variety of incentive savings plans in
which BlackRock, Inc. employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement Savings Plan (RSP), and the BlackRock Employee Stock Purchase Plan (ESPP). The employer contribution components of the RSP include a
company match equal to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal <FONT STYLE="white-space:nowrap">to&nbsp;3-5%&nbsp;of</FONT> eligible compensation up to the
Internal Revenue Service limit ($305,000 for 2022). The RSP offers a range of investment options, including registered investment companies and collective investment funds managed by the firm. BlackRock, Inc. contributions follow the investment
direction set by participants for their own contributions or, absent participant investment direction, are invested into a target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for
investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on
its fair market value on the purchase date. All of the eligible portfolio managers are eligible to participate in these plans. </P>

serve as a portfolio manager of the Trust. </P></TD></TR></TABLE> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Potential Material Conflicts of Interest </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Advisor has built a professional working environment, firm-wide compliance culture and compliance procedures and systems designed to protect against
potential incentives that may favor one account over another. The Advisor has adopted policies and procedures that address the allocation of investment opportunities, execution of portfolio transactions, personal trading by employees and other
potential conflicts of interest that are designed to ensure that all client accounts are treated equitably over time. Nevertheless, the Advisor furnishes investment management and advisory services to numerous clients in addition to the Trust, and
the Advisor may, consistent with applicable law, make investment recommendations to other clients or accounts (including accounts which are hedge funds or have performance or higher fees paid to the Advisor, or in which portfolio managers have a
personal interest in the receipt of such fees), which may be the same as or different from those made to the Trust. In addition, BlackRock, Inc., its affiliates and significant shareholders and any officer, director, shareholder or employee may or
may not have an interest in the securities whose purchase and sale the Advisor recommends to the Trust. BlackRock, Inc., or any of its affiliates or significant shareholders, or any officer, director, shareholder, employee or any member of their
families may take different actions than those recommended to the Trust by the Advisor with respect to the same securities. Moreover, the Advisor may refrain from rendering any advice or services concerning securities of companies of which any of
BlackRock, Inc.&#146;s (or its affiliates&#146; or significant shareholders&#146;) officers, directors or employees are directors or officers, or companies as to which BlackRock, Inc. or any of its affiliates or significant shareholders or the
officers, directors and employees of any of them has any substantial economic interest or possesses <FONT STYLE="white-space:nowrap">material&nbsp;non-public&nbsp;information.</FONT> Certain portfolio managers also may manage accounts whose
investment strategies may at times be opposed to the strategy utilized for a fund. It should also be noted that a portfolio manager may be managing hedge fund and/or long only accounts, or may be part of a team managing hedge fund and/or long only
accounts, subject to incentive fees. Such portfolio managers may therefore be entitled to receive a portion of any incentive fees earned on such accounts. Currently, the portfolio managers of this fund are not entitled to receive a portion of
incentive fees of other accounts. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">As a fiduciary, the Advisor owes a duty of loyalty to its clients and must treat each client fairly. When the Advisor
purchases or sells securities for more than one account, the trades must be allocated in a manner consistent with its fiduciary duties. The Advisor attempts to allocate investments in a fair and equitable manner among client accounts, with no
account receiving preferential treatment. To this end, BlackRock, Inc. has adopted policies that are intended to ensure reasonable efficiency in client transactions and provide the Advisor with sufficient flexibility to allocate investments in a
manner that is consistent with the particular investment discipline and client base, as appropriate. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" ALIGN="center"><B>Shareholders should retain this
