CORPORATION AND OF THE STOCKHOLDERS AND DIRECTORS

Section 5.1 Number, Vacancies, Classification and Election of Directors. The business and affairs of the Corporation shall be managed under the direction of the Board of

Directors. The number of directors of the Corporation initially shall be one, which number may be increased or decreased only by the Board of Directors pursuant to the Bylaws of the Corporation (the “Bylaws”), but shall never be less than the minimum number required by the Maryland General Corporation Law (the “MGCL”). Each director shall have the qualifications, if any, specified in the Bylaws.

Any vacancy on the Board of Directors may be filled in the manner provided in the Bylaws. The Corporation elects, effective at such time as it becomes eligible under Section 3-802 of the MGCL to make the election provided for under Section 3-804(c) of the MGCL, that, except as may be provided by the Board of Directors in setting the terms of any class or series of Preferred Stock (as defined below) or as may be required by the 1940 Act, any and all vacancies on the Board of Directors may be filled only by the affirmative vote of a majority of the directors remaining in office, even if the remaining directors do not constitute a quorum, and any director elected to fill a vacancy shall serve for the remainder of the full term of the directorship in which such vacancy occurred and until a successor is duly elected and qualifies. The name of the director who shall serve until his successor is duly elected and qualifies is Christopher Kelley.

On the first date on which the Corporation has more than one stockholder of record, the directors (other than any director elected solely by holders of one or more classes or series of Preferred Stock in connection with dividend arrearages) shall be classified, with respect to the terms for which they severally hold office, into three classes as determined by the Board of Directors, with a class of directors to hold office initially for a term expiring at the first annual meeting of stockholders subsequent to their election, a class of directors to hold office initially for a term expiring at the second annual meeting of stockholders subsequent to their election, and a class of directors to hold office initially for a term expiring at the third annual meeting of stockholders subsequent to their election, with each director to hold office until her or his successor is duly elected and qualifies. At each annual meeting of the stockholders, commencing with the first annual meeting of stockholders subsequent to the classification of directors, the successors to the class of directors whose term expires at such meeting shall be elected to hold office for a term expiring at the third succeeding annual meeting of stockholders following the meeting at which they were elected and until their successors are duly elected and qualify.

Except as otherwise provided in the Bylaws, each director shall be elected by the affirmative vote of the stockholders entitled to cast a majority of the votes entitled to be cast in the election of directors.

Section 5.2 Extraordinary Actions. Except as specifically provided in Section 5.6 (relating to removal of directors), and in Section 7.2 (relating to certain actions and certain amendments to the charter of the Corporation (the “Charter”)), notwithstanding any provision of law requiring any action to be taken or approved by the affirmative vote of the stockholders entitled to cast a greater number of votes, any such action shall be effective and valid if declared advisable by the Board of Directors and taken or approved by the affirmative vote of stockholders entitled to cast a majority of all the votes entitled to be cast on the matter.

Holders of shares of stock of the Corporation shall not be entitled to exercise any rights of an objecting stockholder provided for under Title 3, Subtitle 2 of the MGCL or any successor statute unless the Board of Directors, upon such terms and conditions as specified by the Board of Directors, shall determine that such rights apply, with respect to all or any shares of all or any classes or series of stock, to one or more transactions occurring after the date of such determination in connection with which holders of such shares would otherwise be entitled to exercise such rights.

Section 5.5 Determinations by Board. The determination as to any of the following matters, made by or pursuant to the direction of the Board of Directors, shall be final and conclusive and shall be binding upon the Corporation and every holder of shares of its stock: the amount of the net income of the Corporation for any period and the amount of assets at any time legally available for the payment of dividends, acquisition of its stock or the payment of other distributions on its stock; the amount of paid-in surplus, net assets, other surplus, cash flow, net profit, net assets in excess of capital, undivided profits or excess of profits over losses on sales of assets; the amount, purpose, time of creation, increase or decrease, alteration or cancellation of any reserves or charges and the propriety thereof (whether or not any obligation or liability for which such reserves or charges shall have been created shall have been paid or discharged); any interpretation or resolution of any ambiguity with respect to any provision of the Charter (including any of the terms, preferences, conversion or other rights, voting powers or rights, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption of any shares of any class or series of stock of the Corporation) or of the Bylaws; the fair value, or any sale, bid or asked price to be applied in determining the fair value, of any asset owned or held by the Corporation or of any shares of stock of the Corporation; the number of shares of stock of any class or series of the Corporation; any matter relating to the acquisition, holding and disposition of any assets by the Corporation; any interpretation of the terms and conditions of one or more agreements with any person, corporation, association, company, trust, partnership (limited or general) or other organization; the compensation of directors, officers, employees or agents of the Corporation; or any other matter relating to the business and affairs of the Corporation or required or permitted by applicable law, the Charter or Bylaws or otherwise to be determined by the Board of Directors.

For the purpose of this paragraph, “cause” shall mean, with respect to any particular director, conviction of a felony or a final judgment of a court of competent jurisdiction holding that such director caused demonstrable, material harm to the Corporation through bad faith or active and deliberate dishonesty.

- 4 -

be made dependent upon facts or events ascertainable outside the Charter (including determinations by the Board of Directors or other facts or events within the control of the Corporation) and may vary among holders thereof, provided that the manner in which such facts, events or variations shall operate upon the terms of such class or series of stock is clearly and expressly set forth in the articles supplementary or other Charter document.

Section 6.5 Inspection of Books and Records. A stockholder that is otherwise eligible under applicable law to inspect the Corporation’s books of account, stock ledger, or other specified documents of the Corporation shall have no right to make such inspection if the Board of Directors, in its sole discretion determines that such stockholder has an improper purpose for requesting such inspection.

PROVISIONS FOR DEFINING, LIMITING

AND REGULATING CERTAIN POWERS OF THE

CORPORATION AND OF THE STOCKHOLDERS AND DIRECTORS

Section 5.1 Number, Vacancies, Classification and Election of Directors. The business and affairs of the Corporation shall be managed under the direction of the Board of

Directors. The number of directors of the Corporation initially shall be one, which number may be increased or decreased only by the Board of Directors pursuant to the Bylaws of the Corporation (the “Bylaws”), but shall never be less than the minimum number required by the Maryland General Corporation Law (the “MGCL”). Each director shall have the qualifications, if any, specified in the Bylaws.

Any vacancy on the Board of Directors may be filled in the manner provided in the Bylaws. The Corporation elects, effective at such time as it becomes eligible under Section 3-802 of the MGCL to make the election provided for under Section 3-804(c) of the MGCL, that, except as may be provided by the Board of Directors in setting the terms of any class or series of Preferred Stock (as defined below) or as may be required by the 1940 Act, any and all vacancies on the Board of Directors may be filled only by the affirmative vote of a majority of the directors remaining in office, even if the remaining directors do not constitute a quorum, and any director elected to fill a vacancy shall serve for the remainder of the full term of the directorship in which such vacancy occurred and until a successor is duly elected and qualifies. The name of the director who shall serve until his successor is duly elected and qualifies is Christopher Kelley.

On the first date on which the Corporation has more than one stockholder of record, the directors (other than any director elected solely by holders of one or more classes or series of Preferred Stock in connection with dividend arrearages) shall be classified, with respect to the terms for which they severally hold office, into three classes as determined by the Board of Directors, with a class of directors to hold office initially for a term expiring at the first annual meeting of stockholders subsequent to their election, a class of directors to hold office initially for a term expiring at the second annual meeting of stockholders subsequent to their election, and a class of directors to hold office initially for a term expiring at the third annual meeting of stockholders subsequent to their election, with each director to hold office until her or his successor is duly elected and qualifies. At each annual meeting of the stockholders, commencing with the first annual meeting of stockholders subsequent to the classification of directors, the successors to the class of directors whose term expires at such meeting shall be elected to hold office for a term expiring at the third succeeding annual meeting of stockholders following the meeting at which they were elected and until their successors are duly elected and qualify.

Except as otherwise provided in the Bylaws, each director shall be elected by the affirmative vote of the stockholders entitled to cast a majority of the votes entitled to be cast in the election of directors.

Section 5.2 Extraordinary Actions. Except as specifically provided in Section 5.6 (relating to removal of directors), and in Section 7.2 (relating to certain actions and certain amendments to the charter of the Corporation (the “Charter”)), notwithstanding any provision of law requiring any action to be taken or approved by the affirmative vote of the stockholders entitled to cast a greater number of votes, any such action shall be effective and valid if declared advisable by the Board of Directors and taken or approved by the affirmative vote of stockholders entitled to cast a majority of all the votes entitled to be cast on the matter.

Section 5.3 Authorization by Board of Stock Issuance. The Board of Directors may authorize the issuance from time to time of shares of stock of the Corporation of any class or series, whether now or hereafter authorized, or securities or rights convertible into shares of its

- 2 -

stock of any class or series, whether now or hereafter authorized, for such consideration, if any, as the Board of Directors may deem advisable (or without consideration in the case of a stock split or stock dividend), subject to such restrictions or limitations, if any, as may be set forth in the Charter or the Bylaws.

Section 5.4 Preemptive Rights and Appraisal Rights. Except as may be provided by the Board of Directors in setting the terms of classified or reclassified shares of stock pursuant to Section 6.4 or as may otherwise be provided by a contract approved by the Board of Directors, no holder of shares of stock of the Corporation shall, as such holder, have any preemptive right to purchase or subscribe for any additional shares of stock of the Corporation or any other security of the Corporation which it may issue or sell. Holders of shares of stock of the Corporation shall not be entitled to exercise any rights of an objecting stockholder provided for under Title 3, Subtitle 2 of the MGCL or any successor statute unless the Board of Directors, upon such terms and conditions as specified by the Board of Directors, shall determine that such rights apply, with respect to all or any shares of all or any classes or series of stock, to one or more transactions occurring after the date of such determination in connection with which holders of such shares would otherwise be entitled to exercise such rights.

Section 5.5 Determinations by Board. The determination as to any of the following matters, made by or pursuant to the direction of the Board of Directors, shall be final and conclusive and shall be binding upon the Corporation and every holder of shares of its stock: the amount of the net income of the Corporation for any period and the amount of assets at any time legally available for the payment of dividends, acquisition of its stock or the payment of other distributions on its stock; the amount of paid-in surplus, net assets, other surplus, cash flow, net profit, net assets in excess of capital, undivided profits or excess of profits over losses on sales of assets; the amount, purpose, time of creation, increase or decrease, alteration or cancellation of any reserves or charges and the propriety thereof (whether or not any obligation or liability for which such reserves or charges shall have been created shall have been paid or discharged); any interpretation or resolution of any ambiguity with respect to any provision of the Charter (including any of the terms, preferences, conversion or other rights, voting powers or rights, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption of any shares of any class or series of stock of the Corporation) or of the Bylaws; the fair value, or any sale, bid or asked price to be applied in determining the fair value, of any asset owned or held by the Corporation or of any shares of stock of the Corporation; the number of shares of stock of any class or series of the Corporation; any matter relating to the acquisition, holding and disposition of any assets by the Corporation; any interpretation of the terms and conditions of one or more agreements with any person, corporation, association, company, trust, partnership (limited or general) or other organization; the compensation of directors, officers, employees or agents of the Corporation; or any other matter relating to the business and affairs of the Corporation or required or permitted by applicable law, the Charter or Bylaws or otherwise to be determined by the Board of Directors.

Section 5.6 Removal of Directors. Subject to the rights of holders of one or more classes or series of Preferred Stock to elect or remove one or more directors, any director, or the entire Board of Directors, may be removed from office at any time, but only for cause and then only by the affirmative vote of at least three-quarters of the votes entitled to be cast generally in the election of directors. For the purpose of this paragraph, “cause” shall mean, with respect to any particular director, conviction of a felony or a final judgment of a court of competent jurisdiction holding that such director caused demonstrable, material harm to the Corporation through bad faith or active and deliberate dishonesty.

- 3 -

Section 5.7 Corporate Opportunities. The Corporation shall have the power, by resolution of the Board of Directors, to renounce any interest or expectancy of the Corporation in, or in being offered an opportunity to participate in, business opportunities or classes or categories of business opportunities that are presented to the Corporation or developed by or presented to one or more directors or officers of the Corporation.

ARTICLE VI

STOCK

Section 6.1 Authorized Shares. The Corporation has authority to issue 1,100,000,000 shares of stock, initially consisting of 1,000,000,000 shares of common stock, $0.001 par value per share (“Common Stock”), and 100,000,000 shares of preferred stock, $0.001 par value per share (“Preferred Stock”). The aggregate par value of all authorized shares of stock having par value is $1,100,000. If shares of one class or series of stock are classified or reclassified into shares of another class or series of stock pursuant to this Article VI, the number of authorized shares of the former class or series shall be automatically decreased and the number of shares of the latter class or series shall be automatically increased, in each case by the number of shares so classified or reclassified, so that the aggregate number of shares of stock of all classes and series that the Corporation has authority to issue shall not be more than the total number of shares of stock set forth in the first sentence of this paragraph. The Board of Directors, with the approval of a majority of the entire Board of Directors and without any action by the stockholders of the Corporation, may amend the Charter from time to time to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class or series that the Corporation has authority to issue.

Section 6.2 Common Stock. Each share of Common Stock shall entitle the holder thereof to one vote. The Board of Directors may reclassify any unissued shares of Common Stock from time to time in one or more classes or series of stock.

Section 6.3 Preferred Stock. The Board of Directors may classify any unissued shares of Preferred Stock and reclassify any previously classified but unissued shares of Preferred Stock.

Section 6.4 Classified or Reclassified Shares. Prior to issuance of classified or reclassified shares of any class or series, the Board of Directors by resolution shall: (a) designate that class or series to distinguish it from all other classes and series of stock of the Corporation; (b) specify the number of shares to be included in the class or series; (c) set or change, subject to the express terms of any class or series of stock of the Corporation outstanding at the time, the preferences, conversion or other rights, voting powers (including exclusive voting rights, if any), restrictions, limitations as to dividends or other distributions, qualifications and terms and conditions of redemption for each class or series; and (d) cause the Corporation to file articles supplementary with the State Department of Assessments and Taxation of Maryland. Any of the terms of any class or series of stock set or changed pursuant to clause (c) of this Section 6.4 may

- 4 -

be made dependent upon facts or events ascertainable outside the Charter (including determinations by the Board of Directors or other facts or events within the control of the Corporation) and may vary among holders thereof, provided that the manner in which such facts, events or variations shall operate upon the terms of such class or series of stock is clearly and expressly set forth in the articles supplementary or other Charter document.

Section 6.5 Inspection of Books and Records. A stockholder that is otherwise eligible under applicable law to inspect the Corporation’s books of account, stock ledger, or other specified documents of the Corporation shall have no right to make such inspection if the Board of Directors, in its sole discretion determines that such stockholder has an improper purpose for requesting such inspection.

Section 6.6 Charter and Bylaws. The rights of all stockholders and the terms of all stock of the Corporation are subject to the provisions of the Charter and the Bylaws. The Board of Directors shall have the exclusive power to make, alter, amend or repeal the Bylaws.

Section 6.7 Special Meetings of Stockholders. A special meeting of stockholders requested by the stockholders may only be called upon the request of stockholders entitled to cast not less than a majority of all the votes entitled to be cast on such matter at such meeting in accordance with the Bylaws.

ARTICLE II

MEETINGS OF STOCKHOLDERS

Section 1. PLACE. All meetings of stockholders shall be held at the principal executive office of the Corporation or at such other place as shall be set in accordance with these Bylaws and stated in the notice of the meeting.

Section 2. ANNUAL MEETING. An annual meeting of stockholders for the election of directors and the transaction of any business within the powers of the Corporation shall be held on the date and at the time and place set by the Board of Directors.

Section 3. SPECIAL MEETINGS.

(a) General. Each of the chair of the board, chief executive officer, president and Board of Directors may call a special meeting of stockholders. Except as provided in subsection (b)(4) of this Section 3, a special meeting of stockholders shall be held on the date and at the time and place set by the chair of the board, chief executive officer, president or Board of Directors, whoever has called the meeting. Subject to subsection (b) of this Section 3, a special meeting of stockholders shall also be called by the secretary of the Corporation to act on any matter that may properly be considered at a meeting of stockholders upon the written request of stockholders entitled to cast not less than a majority of all the votes entitled to be cast on such matter at such meeting (the “Special Meeting Percentage”).

(b) Stockholder-Requested Special Meetings. (1) Any stockholder of record seeking to have stockholders request a special meeting shall, by sending written notice to the secretary (the “Record Date Request Notice”) by registered mail, return receipt requested, request the Board of Directors to fix a record date to determine the stockholders entitled to request a special meeting (the “Request Record Date”). The Record Date Request Notice shall set forth the purpose of the meeting and the matters proposed to be acted on at it, shall be signed by one or more stockholders of record as of the date of signature (or their agents duly authorized in a writing accompanying the Record Date Request Notice), shall bear the date of signature of

each such stockholder (or such agent) and shall set forth all information relating to each such stockholder and each matter proposed to be acted on at the meeting that would be required to be disclosed in connection with the solicitation of proxies for the election of directors in an election contest (even if an election contest is not involved), or would otherwise be required in connection with such a solicitation, in each case pursuant to Regulation 14A (or any successor provision) under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “Exchange Act”). Upon receiving the Record Date Request Notice, the Board of Directors may fix a Request Record Date. The Request Record Date shall not precede and shall not be more than ten days after the close of business on the date on which the resolution fixing the Request Record Date is adopted by the Board of Directors. If the Board of Directors, within 30 days after the date on which a valid Record Date Request Notice is received, fails to adopt a resolution fixing the Request Record Date, the Request Record Date shall be the close of business on the 30th day after the first date on which a Record Date Request Notice is received by the secretary or, if such 30^th day is not a Business Day (as defined below), on the first preceding Business Day.

(2) In order for any stockholder to request a special meeting to act on any matter that may properly be considered at a meeting of stockholders, one or more written requests for a special meeting (collectively, the “Special Meeting Request”) signed by stockholders of record (or their agents duly authorized in a writing accompanying the request) as of the Request Record Date entitled to cast not less than the Special Meeting Percentage shall be delivered to the secretary. In addition, the Special Meeting Request shall (a) set forth the purpose of the meeting and the matters proposed to be acted on at it (which shall be limited to those lawful matters set forth in the Record Date Request Notice received by the secretary), (b) bear the date of signature of each such stockholder (or such agent) signing the Special Meeting Request, (c) set forth (i) the name and address, as they appear in the Corporation’s books, of each stockholder signing such request (or on whose behalf the Special Meeting Request is signed), (ii) the class, series and number of all shares of stock of the Corporation which are owned (beneficially or of record) by each such stockholder and (iii) the nominee holder for, and number of, shares of stock of the Corporation owned beneficially but not of record by such stockholder, (d) be sent to the secretary by registered mail, return receipt requested, and (e) be received by the secretary within 60 days after the Request Record Date. Any requesting stockholder (or agent duly authorized in a writing accompanying the revocation of the Special Meeting Request) may revoke his, her or its request for a special meeting at any time by written revocation delivered to the secretary.

(3) The secretary shall inform the requesting stockholders of the reasonably estimated cost of preparing and mailing or delivering the notice of the meeting (including the Corporation’s proxy materials). The secretary shall not be required to call a special meeting upon stockholder request and such meeting shall not be held unless, in addition to the documents required by paragraph (2) of this Section 3(b), the secretary receives payment of such reasonably estimated cost prior to the preparation and mailing or delivery of such notice of the meeting.

(4) In the case of any special meeting called by the secretary upon the request of stockholders (a “Stockholder-Requested Meeting”), such meeting shall be held at such place, date and time as may be designated by the Board of Directors; provided, however, that the

2

date of any Stockholder-Requested Meeting shall be not more than 90 days after the record date for such meeting (the “Meeting Record Date”); and provided further that if the Board of Directors fails to designate, within ten days after the date that a valid Special Meeting Request is actually received by the secretary (the “Delivery Date”), a date and time for a Stockholder-Requested Meeting, then such meeting shall be held at 2:00 p.m., local time, on the 90^th day after the Meeting Record Date or, if such 90^th day is not a Business Day (as defined below), on the first preceding Business Day; and provided further that in the event that the Board of Directors fails to designate a place for a Stockholder-Requested Meeting within ten days after the Delivery Date, then such meeting shall be held at the principal executive office of the Corporation. In fixing a date for a Stockholder-Requested Meeting, the Board of Directors may consider such factors as it deems relevant, including, without limitation, the nature of the matters to be considered, the facts and circumstances surrounding any request for the meeting and any plan of the Board of Directors to call an annual meeting or a special meeting. In the case of any Stockholder-Requested Meeting, if the Board of Directors fails to fix a Meeting Record Date that is a date within 30 days after the Delivery Date, then the close of business on the 30^th day after the Delivery Date or, if such 30^th day after the Delivery Date is not a Business Day (as defined below), the first preceding Business Day, shall be the Meeting Record Date. The Board of Directors may revoke the notice for any Stockholder-Requested Meeting in the event that the requesting stockholders fail to comply with the provisions of paragraph (3) of this Section 3(b).

(5) If written revocations of the Special Meeting Request have been delivered to the secretary and the result is that stockholders of record (or their agents duly authorized in writing), as of the Request Record Date, entitled to cast less than the Special Meeting Percentage have delivered, and not revoked, requests for a special meeting on the matter to the secretary: (i) if the notice of meeting has not already been delivered, the secretary shall refrain from delivering the notice of the meeting and send to all requesting stockholders who have not revoked such requests written notice of any revocation of a request for a special meeting on the matter, or (ii) if the notice of meeting has been delivered and if the secretary first sends to all requesting stockholders who have not revoked requests for a special meeting on the matter written notice of any revocation of a request for the special meeting and written notice of the Corporation’s intention to revoke the notice of the meeting or for the chair of the meeting to adjourn the meeting without action on the matter, (A) the secretary may revoke the notice of the meeting at any time before ten days before the commencement of the meeting or (B) the chair of the meeting may call the meeting to order and adjourn the meeting from time to time without acting on the matter. Any request for a special meeting received after a revocation by the secretary of a notice of a meeting shall be considered a request for a new special meeting.

(6) The chair of the board, chief executive officer, president or Board of Directors may appoint regionally or nationally recognized independent inspectors of elections to act as the agent of the Corporation for the purpose of promptly performing a ministerial review of the validity of any purported Special Meeting Request received by the secretary. For the purpose of permitting the inspectors to perform such review, no such purported Special Meeting Request shall be deemed to have been received by the secretary until the earlier of (i) five Business Days after actual receipt by the secretary of such purported request and (ii) such date as the independent inspectors certify to the Corporation that the valid requests received by the secretary represent, as of the Request Record Date, stockholders of record entitled to cast not less than the Special Meeting Percentage. Nothing contained in this paragraph (6) shall in any

3

way be construed to suggest or imply that the Corporation or any stockholder shall not be entitled to contest the validity of any request, whether during or after such five Business Day period, or to take any other action (including, without limitation, the commencement, prosecution or defense of any litigation with respect thereto, and the seeking of injunctive relief in such litigation).

(7) For purposes of these Bylaws, “Business Day” shall mean any day other than a Saturday, a Sunday or a day on which banking institutions in the State of New York are authorized or obligated by law or executive order to close.

Section 4. NOTICE OF MEETINGS. Not less than ten nor more than 90 days before each meeting of stockholders, the secretary shall give to each stockholder entitled to vote at such meeting and to each stockholder not entitled to vote who is entitled to notice of the meeting notice in writing or by electronic transmission stating the time and place of the meeting and, in the case of a special meeting or as otherwise may be required by any statute, the purpose for which the meeting is called, by mail, by presenting it to such stockholder personally, by leaving it at the stockholder’s residence or usual place of business, by electronic transmission or by any other means permitted by Maryland law. If mailed, such notice shall be deemed to be given when deposited in the United States mail addressed to the stockholder at the stockholder’s address as it appears on the records of the Corporation, with postage thereon prepaid. If transmitted electronically, such notice shall be deemed to be given when transmitted to the stockholder by an electronic transmission to any address or number of the stockholder at which the stockholder receives electronic transmissions. The Corporation may give a single notice to all stockholders who share an address, which single notice shall be effective as to any stockholder at such address, unless such stockholder objects to receiving such single notice or revokes a prior consent to receiving such single notice. Failure to give notice of any meeting to one or more stockholders, or any irregularity in such notice, shall not affect the validity of any meeting fixed in accordance with this Article II or the validity of any proceedings at any such meeting. Such notice will also specify the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting.

Subject to Section 11(a) of this Article II, any business of the Corporation may be transacted at an annual meeting of stockholders without being specifically designated in the notice, except such business as is required by any statute to be stated in such notice. No business shall be transacted at a special meeting of stockholders except as specifically designated in the notice. The Corporation may postpone or cancel a meeting of stockholders by making a public announcement (as defined in Section 11(c)(3) of this Article II) of such postponement or cancellation prior to the meeting. Notice of the date, time and place to which the meeting is postponed shall be given not less than ten days prior to such date and otherwise in the manner set forth in this section.

Section 5. ORGANIZATION AND CONDUCT. Every meeting of stockholders shall be conducted by an individual appointed by the Board of Directors to be chair of the meeting or, in the absence of such appointment or appointed individual, by the chair of the board or, in the case of a vacancy in the office or absence of the chair of the board, by one of the following individuals present at the meeting in the following order: the lead independent director, if there is one, the chief executive officer, the president, the vice presidents in their

4

order of rank and, within each rank, in their order of seniority, the secretary, or, in the absence of such officers, a chair chosen by the stockholders by the vote of a majority of the votes cast by stockholders present in person or by proxy. The secretary or, in the case of a vacancy in the office or absence of the secretary, an assistant secretary or an individual appointed by the Board of Directors or the chair of the meeting shall act as secretary. In the event that the secretary presides at a meeting of stockholders, an assistant secretary, or, in the absence of all assistant secretaries, an individual appointed by the Board of Directors or the chair of the meeting, shall record the minutes of the meeting. Even if present at the meeting, the person holding the office named herein may delegate to another person the power to act as chair or secretary of the meeting. The order of business and all other matters of procedure at any meeting of stockholders shall be determined by the chair of the meeting. The chair of the meeting may prescribe such rules, regulations and procedures and take such action as, in the discretion of the chair and without any action by the stockholders, are appropriate for the proper conduct of the meeting, including, without limitation, (a) restricting admission to the time set for the commencement of the meeting; (b) limiting attendance or participation at the meeting to stockholders of record of the Corporation, their duly authorized proxies and such other individuals as the chair of the meeting may determine; (c) recognizing speakers at the meeting and determining when and for how long speakers and any individual speaker may address the meeting; (d) determining when and for how long the polls should be opened and when the polls should be closed and when announcement of the results should be made; (e) maintaining order and security at the meeting; (f) removing any stockholder or any other individual who refuses to comply with meeting procedures, rules or guidelines as set forth by the chair of the meeting; (g) concluding a meeting or recessing or adjourning the meeting (with respect to one or more matters to be considered at such meeting), whether or not a quorum is present, to a later date and time and at a place announced at the meeting; and (h) complying with any state and local laws and regulations concerning safety and security. Unless otherwise determined by the chair of the meeting, meetings of stockholders shall not be required to be held in accordance with any rules of parliamentary procedure.

Section 6. QUORUM. The presence in person or by proxy of stockholders entitled to cast a majority of the votes entitled to be cast at the meeting (without regard to class) shall constitute a quorum at any meeting of the stockholders, except with respect to any matter that, under applicable law or regulatory requirements or the charter of the Corporation (the “Charter”), requires approval by a separate vote of the holders of one or more classes of stock, in which case the presence in person or by proxy of stockholders entitled to cast a majority of the votes entitled to be cast by holders of stock of each such class on such a matter shall constitute a quorum. This section shall not affect any requirement under law or the Charter for the vote necessary for the approval of any matter.

If, however, such quorum is not established at any meeting of the stockholders, the chair of the meeting may adjourn the meeting sine die or from time to time to a date not more than 120 days after the original record date without notice other than announcement at the meeting. At such adjourned meeting at which a quorum shall be present, any business may be transacted which might have been transacted at the meeting as originally notified.

The stockholders present either in person or by proxy, at a meeting which has been duly called and at which a quorum has been established, may continue to transact business until adjournment, notwithstanding the withdrawal from the meeting of enough stockholders to leave fewer than required to establish a quorum.

5

Section 7. VOTING. A majority of all the votes entitled to be cast at a meeting of stockholders duly called and at which a quorum is present shall be sufficient to elect a director. Each share entitles the holder thereof to cast one vote for as many individuals as there are directors to be elected and for whose election the holder of such share is entitled to vote. A majority of the votes cast at a meeting of stockholders duly called and at which a quorum is present shall be sufficient to approve any other matter which may properly come before the meeting, unless a different number or proportion is required by any law or the Charter. Unless otherwise provided by any law or the Charter, each outstanding share, regardless of class, entitles the holder thereof to cast one vote on each matter submitted to a vote at a meeting of stockholders and fractional shares shall be entitled to a proportionate fractional vote on any matter submitted to a vote of stockholders.

Section 8. PROXIES. A stockholder of record may cast votes in person or by proxy executed by the stockholder or by the stockholder’s duly authorized agent in any manner permitted by law. Such proxy or evidence of authorization of such proxy shall be filed with the secretary of the Corporation before or at the meeting. No proxy shall be valid more than eleven months after its date unless otherwise provided in the proxy.

Section 9. VOTING OF STOCK BY CERTAIN HOLDERS. Stock of the Corporation registered in the name of a corporation, limited liability company, partnership, joint venture, trust or other entity, if entitled to be voted, may be voted by the president or a vice president, managing member, manager, general partner or trustee thereof, as the case may be, or a proxy appointed by any of the foregoing individuals, unless some other person who has been appointed to vote such stock pursuant to a bylaw or a resolution of the governing body of such corporation or other entity or agreement of the partners of a partnership presents a certified copy of such bylaw, resolution or agreement, in which case such person may vote such stock. Any trustee or fiduciary, in such capacity, may vote stock registered in such trustee’s or fiduciary’s name, either in person or by proxy.

Shares of stock of the Corporation directly or indirectly owned by it shall not be voted at any meeting and shall not be counted in determining the total number of outstanding shares entitled to be voted at any given time, unless they are held by it in a fiduciary capacity, in which case they may be voted and shall be counted in determining the total number of outstanding shares at any given time.

The Board of Directors may adopt by resolution a procedure by which a stockholder may certify in writing to the Corporation that any shares of stock registered in the name of the stockholder are held for the account of a specified person other than the stockholder. The resolution shall set forth the class of stockholders who may make the certification, the purpose for which the certification may be made, the form of certification and the information to be contained in it; if the certification is with respect to a record date, the time after the record date within which the certification must be received by the Corporation; and any other provisions with respect to the procedure which the Board of Directors considers necessary or desirable. On receipt by the Corporation of such certification, the person specified in the certification shall be regarded as, for the purposes set forth in the certification, the holder of record of the specified stock in place of the stockholder who makes the certification.

Section 10. INSPECTORS. The Board of Directors or the chair of the meeting may appoint, before or at the meeting, one or more inspectors for the meeting and any successor to the inspector. Except as otherwise provided by the chair of the meeting, the inspectors, if any, shall (i) determine the number of shares of stock represented at the meeting, in person or by proxy, and the validity and effect of proxies, (ii) receive and tabulate all votes, ballots or consents, (iii) report such tabulation to the chair of the meeting, (iv) hear and determine all challenges and questions arising in connection with the right to vote, and (v) do such acts as are proper to fairly conduct the election or vote. Each such report shall be in writing and signed by the inspector or by a majority of them if there is more than one inspector acting at such meeting. If there is more than one inspector, the report of a majority shall be the report of the inspectors. The report of the inspector or inspectors on the number of shares represented at the meeting and the results of the voting shall be prima facie evidence thereof.

Section 11. ADVANCE NOTICE OF STOCKHOLDER NOMINEES FOR DIRECTOR AND OTHER STOCKHOLDER PROPOSALS.

(a) Annual Meetings of Stockholders. (1) Nominations of individuals for election to the Board of Directors and the proposal of other business to be considered by the stockholders may be made at an annual meeting of stockholders (i) pursuant to the Corporation’s notice of meeting, (ii) by or at the direction of the Board of Directors or (iii) by any stockholder of the Corporation who was a stockholder of record at the record date set by the Board of Directors for the purpose of determining stockholders entitled to vote at the annual meeting, at the time of giving of notice by the stockholder as provided for in this Section 11(a) and at the time of the annual meeting (and any postponement or adjournment thereof), who is entitled to vote at the meeting in the election of each individual so nominated or on any such other business and who has complied with this Section 11(a).

(2) In addition to complying with any other requirements under all applicable federal and state laws, including the Exchange Act and the rules and regulations thereunder, and the Charter and these Bylaws, for any nomination or other business to be properly brought before an annual meeting by a stockholder pursuant to clause (iii) of paragraph (a)(1) of this Section 11, the stockholder must have given timely notice thereof in writing to the secretary of the Corporation and, in the case of any such other business, such other business must otherwise be a proper matter for action by the stockholders. To be timely, a stockholder’s notice shall set forth all information required under this Section 11 and shall be delivered to the secretary at the principal executive office of the Corporation not earlier than the 150^th day nor later than 5:00 p.m., Eastern Time, on the 120^th day prior to the first anniversary of the date of the proxy statement (as defined in Section 11(c)(3) of this Article II) for the preceding year’s annual meeting; provided, however, that, in the event that the date of the annual meeting is advanced or delayed by more than 30 days from the first anniversary of the date of the preceding year’s annual meeting, in order for notice by the stockholder to be timely, such notice must be so delivered not earlier than the 150^th day prior to the date of such annual meeting and not later than 5:00 p.m., Eastern Time, on the later of the 120^th day prior to the date of such annual meeting, as originally convened, or the tenth day following the day on which public announcement of the

7

date of such meeting is first made; provided further, that, for notice of any nomination or other business to be properly brought before the 2021 annual meeting of stockholders, to be timely, a stockholder’s notice shall set forth all information required under this Section 11, and shall be delivered to the secretary of the Corporation at the principal executive office of the Corporation not earlier than the 120^th day nor later than 5:00 p.m., Eastern Time, on the 90^th day prior to the first anniversary of the date of the proxy statement for the preceding year’s annual meeting. The public announcement of a postponement or adjournment of an annual meeting shall not commence a new time period for the giving of a stockholder’s notice as described above. If a stockholder of record is entitled to vote only for a specific class or category of directors at a meeting (annual or special), such stockholder’s right to nominate one or more individuals for election as a director at the meeting shall be limited to such class or category of directors.

(3) Such stockholder’s notice shall set forth:

(B) a representation that the Proposed Nominee is not and will not be an “interested person” of the Corporation (as defined in the Investment Company Act of 1940, as amended (the “1940 Act”)), and information regarding the Proposed Nominee that will be sufficient, in the discretion of the Board of Directors, for the Corporation to confirm such representation; and

(C) a representation that the Proposed Nominee meets all applicable legal requirements relevant to service as a director, including, but not limited to, the rules adopted by the principal listing exchange (if any) upon which Corporation’s securities are listed, Rule 10A-3 under the Exchange Act (or any successor provision thereto), Article 2-01 of Regulation S-X under the Exchange Act with respect to the Corporation’s independent registered public accounting firm (or any successor provision thereto) and any other criteria established by the 1940 Act related to service as a director of a management investment company or the permitted composition of the board of directors of a management investment company, together with information regarding such Proposed Nominee that will be sufficient, in the discretion of the Board of Directors, to confirm such representation;

(C) whether and the extent to which such stockholder, Proposed Nominee or Stockholder Associated Person, directly or indirectly (through brokers, nominees or otherwise), is subject to or during the last twelve months has engaged in any hedging, derivative or other transaction or series of transactions or entered into any other agreement, arrangement or understanding (including any short interest, any borrowing or lending of securities or any proxy or voting agreement), the effect or intent of which is to (I) manage risk or benefit of changes in the price of (x) Company Securities or (y) any security of any other closed-end investment company (a “Peer Group Company”) for such stockholder, Proposed Nominee or Stockholder Associated Person or (II) increase or decrease the voting power of such stockholder, Proposed Nominee or Stockholder Associated Person in the Corporation or any affiliate thereof (or, as applicable, in any Peer Group Company) disproportionately to such person’s economic interest in the Company Securities (or, as applicable, in any Peer Group Company); and

(D) any substantial interest, direct or indirect (including, without limitation, any existing or prospective commercial, business or contractual relationship with the Corporation), by security holdings or otherwise, of such stockholder, Proposed Nominee or Stockholder Associated Person, in the Corporation or any affiliate thereof, other than an interest arising from the ownership of Company Securities where such stockholder, Proposed Nominee or Stockholder Associated Person receives no extra or special benefit not shared on a pro rata basis by all other holders of the same class or series;

(C) a description of all agreements, arrangements and understandings (whether written or oral) and relationships with respect to the nomination or proposal between or among the stockholder, any Stockholder Associated Person, and any other person or persons (including their names) in connection with the nomination or proposal of such business, and any material interest of such person in such nomination or business, including any anticipated benefit therefrom to such person; and

(4) Such stockholder’s notice shall, with respect to any Proposed Nominee, be accompanied by a written undertaking executed by the Proposed Nominee (i) certifying that such Proposed Nominee (a) is not, and will not become a party to, any agreement, arrangement or understanding with any person or entity other than the Corporation in connection with service or action as a director that has not been disclosed to the Corporation and (b) will serve as a director of the Corporation if elected; and (ii) attaching a completed Proposed Nominee questionnaire (which questionnaire shall be provided by the Corporation, upon request, to the stockholder providing the notice and shall include all information relating to the Proposed Nominee that would be required to be disclosed in connection with the solicitation of proxies for the election of the Proposed Nominee as a director in an election contest (even if an election contest is not involved), or would otherwise be required in connection with such solicitation, in each case pursuant to Regulation 14A (or any successor provision) under the Exchange Act, or would be required pursuant to the rules of any national securities exchange or over-the-counter market on which the Corporation’s securities are listed or traded).

(5) The Proposed Nominee shall, as required by the Board of Directors, sit for an interview with one or more directors or their representatives, which interview may, in the discretion of the Board of Directors be conducted by means of remote communication. Refusal by a Proposed Nominee to participate in such interview will render the nomination ineffective for failure to satisfy the requirements of these Bylaws. The Proposed Nominee shall, as required by the Board of Directors, consent to and cooperate with a background screening conducted by a background screening company selected by the Board of Directors with experience in conducting background screenings of public company directors. Refusal by a Proposed Nominee to cooperate with such a background screening will render the nomination ineffective for failure to satisfy the requirements of these Bylaws.

10

(6) For a stockholder notice to comply with the requirements of this Section 11, each of the requirements of this Section 11 shall be directly and expressly responded to and such stockholder notice must clearly indicate and expressly reference, for all information disclosed in the stockholder notice, the provisions of this Section 11 for which such information is provided.

(7) Notwithstanding anything in this subsection (a) of this Section 11 to the contrary, in the event that the number of directors to be elected to the Board of Directors is increased, and there is no public announcement of such action at least 130 days prior to the first anniversary of the date of the proxy statement (as defined in Section 11(c)(3) of this Article II) for the preceding year’s annual meeting, a stockholder’s notice required by this Section 11(a) shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the secretary at the principal executive office of the Corporation not later than 5:00 p.m., Eastern Time, on the tenth day following the day on which such public announcement is first made by the Corporation.

(8) For purposes of this Section 11, “Stockholder Associated Person” of any stockholder means (i) any person acting in concert with such stockholder, (ii) any beneficial owner of shares of stock of the Corporation owned of record or beneficially by such stockholder (other than a stockholder that is a depositary) and (iii) any person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, such stockholder or such Stockholder Associated Person or is an officer, director, partner, member, employee or agent of such stockholder or such Stockholder Associated Person.

(b) Special Meetings of Stockholders. Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the Corporation’s notice of meeting. Nominations of individuals for election to the Board of Directors may be made at a special meeting of stockholders at which directors are to be elected only (i) by or at the direction of the Board of Directors or (ii) provided that the special meeting has been called in accordance with Section 3 of this Article II for the purpose of electing directors, by any stockholder of the Corporation who is a stockholder of record at the record date set by the Board of Directors for the purpose of determining stockholders entitled to vote at the special meeting, at the time of giving of notice provided for in this Section 11 and at the time of the special meeting (and any postponement or adjournment thereof), who is entitled to vote at the meeting in the election of each individual so nominated and who has complied with the notice procedures set forth in this Section 11. In the event the Corporation calls a special meeting of stockholders for the purpose of electing one or more individuals to the Board of Directors, any such stockholder may nominate an individual or individuals (as the case may be) for election as a director as specified in the Corporation’s notice of meeting, if the stockholder’s notice, containing the information required by paragraphs (a)(3) and (4) of this Section 11 shall be delivered to the secretary at the principal executive office of the Corporation not earlier than the 120^th day prior to such special meeting and not later than 5:00 p.m., Eastern Time, on the later of the 90^th day prior to such special meeting or the tenth day following the day on which public

11

announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting. Any individual nominated in accordance with this paragraph (b) of this Section 11 shall be obligated to comply with paragraph (a)(5) of this Section 11. The public announcement of a postponement or adjournment of a special meeting shall not commence a new time period for the giving of a stockholder’s notice as described above.

(c) General. (1) If information submitted pursuant to this Section 11 by any stockholder proposing a nominee for election as a director or any proposal for other business at a meeting of stockholders shall be inaccurate in any material respect, or if the stockholder otherwise fails to comply with this Section 11, such information, nomination or proposal may be deemed not to have been provided or made in accordance with this Section 11. Any such stockholder shall notify the Corporation of any inaccuracy or change (within two Business Days of becoming aware of such inaccuracy or change) in any such information. Upon written request by the secretary of the Corporation or the Board of Directors, any such stockholder shall provide, within five Business Days of delivery of such request (or such other period as may be specified in such request), (A) written verification, satisfactory, in the discretion of the Board of Directors or any authorized officer of the Corporation, to demonstrate the accuracy of any information submitted by the stockholder pursuant to this Section 11, and (B) a written update of any information (including, if requested by the Corporation, written confirmation by such stockholder that it continues to intend to bring such nomination or other business proposal before the meeting) submitted by the stockholder pursuant to this Section 11 as of an earlier date. If a stockholder fails to provide such written verification or written update within such period, the information as to which written verification or a written update was requested may be deemed not to have been provided in accordance with this Section 11.

(2) Only such individuals who are nominated in accordance with this Section 11 shall be eligible for election by stockholders as directors, and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with this Section 11. The chair of the meeting shall have the power to determine whether a nomination or any other business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with this Section 11. Determinations by the chair of the meeting with respect to compliance of any proposed nomination or business and/or any information submitted to the Corporation by a stockholders or a Proposed Nominee pursuant to this Section 11 shall be final and binding unless determined by a court of competent jurisdiction to have been made in bad faith.

(3) For purposes of this Section 11, (A) “the date of the proxy statement” shall have the same meaning as “the date of the company’s proxy statement released to shareholders” as used in Rule 14a-8(e), as interpreted by the Securities and Exchange Commission from time to time, (B) with respect to the 2021 Annual Meeting of Stockholders, the “preceding year’s annual meeting” shall mean the 2020 annual meeting of shareholders of Pioneer Municipal High Income Trust, and (C) “Public announcement” shall mean disclosure (i) in a press release reported by the Dow Jones News Service, Associated Press, Business Wire, PR Newswire or other widely circulated news or wire service or (ii) in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to the Exchange Act or the 1940 Act.

12

(4) Notwithstanding the foregoing provisions of this Section 11, and in addition to the requirements thereof, a stockholder shall also have complied with all applicable requirements of state law and of the 1940 Act and the Exchange Act with respect to the acquisition, holding or voting of shares, the disclosure of beneficial ownership of shares or changes therein, the disclosure of any intention to make any proposals with respect to the Corporation or that would affect the management or control of the Corporation, all other required disclosures, and the solicitation of proxies or written consents, or otherwise related to the matters set forth in this Section 11. Nothing in this Section 11 shall be deemed to affect any right of a stockholder to request inclusion of a proposal in, or the right of the Corporation to omit a proposal from, the Corporation’s proxy statement pursuant to Rule 14a-8 (or any successor provision) under the Exchange Act. Nothing in this Section 11 shall require disclosure of revocable proxies received by the stockholder or Stockholder Associated Person pursuant to a solicitation of proxies after the filing of an effective Schedule 14A by such stockholder or Stockholder Associated Person under Section 14(a) of the Exchange Act.

(5) Notwithstanding anything in these Bylaws to the contrary, except as otherwise determined by the chair of the meeting, if the stockholder giving notice as provided for in this Section 11 does not appear in person or by proxy at such annual or special meeting to present each nominee for election as a director or the proposed business, as applicable, such matter shall not be considered at the meeting.

Section 12. VOTING BY BALLOT. Voting on any question or in any election may be viva voce unless the presiding officer shall order or any stockholder shall demand that voting be by ballot.

Section 13. MARYLAND CONTROL SHARE ACQUISITION ACT. Pursuant to a resolution adopted by the Board of Directors in accordance with Section 3-702(c)(4) of the Maryland General Corporation Law (the “MGCL”), the Corporation is subject to Title 3, Subtitle 7 of the MGCL (the “Control Share Act”), which shall apply to any acquisition or proposed acquisition of shares of stock of the Corporation to the extent provided in the Control Share Act. Notwithstanding the foregoing sentence, the Control Share Act shall not apply to the voting rights of the holders of any shares of preferred stock of the Corporation (but only with respect to such shares).

Except as provided in subsection (b)(4) of this Section 3, a special meeting of stockholders shall be held on the date and at the time and place set by the chair of the board, chief executive officer, president or Board of Directors, whoever has called the meeting. Subject to subsection (b) of this Section 3, a special meeting of stockholders shall also be called by the secretary of the Corporation to act on any matter that may properly be considered at a meeting of stockholders upon the written request of stockholders entitled to cast not less than a majority of all the votes entitled to be cast on such matter at such meeting (the “Special Meeting Percentage”).

(b) Stockholder-Requested Special Meetings. (1) Any stockholder of record seeking to have stockholders request a special meeting shall, by sending written notice to the secretary (the “Record Date Request Notice”) by registered mail, return receipt requested, request the Board of Directors to fix a record date to determine the stockholders entitled to request a special meeting (the “Request Record Date”). The Record Date Request Notice shall set forth the purpose of the meeting and the matters proposed to be acted on at it, shall be signed by one or more stockholders of record as of the date of signature (or their agents duly authorized in a writing accompanying the Record Date Request Notice), shall bear the date of signature of

each such stockholder (or such agent) and shall set forth all information relating to each such stockholder and each matter proposed to be acted on at the meeting that would be required to be disclosed in connection with the solicitation of proxies for the election of directors in an election contest (even if an election contest is not involved), or would otherwise be required in connection with such a solicitation, in each case pursuant to Regulation 14A (or any successor provision) under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “Exchange Act”). Upon receiving the Record Date Request Notice, the Board of Directors may fix a Request Record Date. The Request Record Date shall not precede and shall not be more than ten days after the close of business on the date on which the resolution fixing the Request Record Date is adopted by the Board of Directors. If the Board of Directors, within 30 days after the date on which a valid Record Date Request Notice is received, fails to adopt a resolution fixing the Request Record Date, the Request Record Date shall be the close of business on the 30th day after the first date on which a Record Date Request Notice is received by the secretary or, if such 30^th day is not a Business Day (as defined below), on the first preceding Business Day.

(2) In order for any stockholder to request a special meeting to act on any matter that may properly be considered at a meeting of stockholders, one or more written requests for a special meeting (collectively, the “Special Meeting Request”) signed by stockholders of record (or their agents duly authorized in a writing accompanying the request) as of the Request Record Date entitled to cast not less than the Special Meeting Percentage shall be delivered to the secretary. In addition, the Special Meeting Request shall (a) set forth the purpose of the meeting and the matters proposed to be acted on at it (which shall be limited to those lawful matters set forth in the Record Date Request Notice received by the secretary), (b) bear the date of signature of each such stockholder (or such agent) signing the Special Meeting Request, (c) set forth (i) the name and address, as they appear in the Corporation’s books, of each stockholder signing such request (or on whose behalf the Special Meeting Request is signed), (ii) the class, series and number of all shares of stock of the Corporation which are owned (beneficially or of record) by each such stockholder and (iii) the nominee holder for, and number of, shares of stock of the Corporation owned beneficially but not of record by such stockholder, (d) be sent to the secretary by registered mail, return receipt requested, and (e) be received by the secretary within 60 days after the Request Record Date. Any requesting stockholder (or agent duly authorized in a writing accompanying the revocation of the Special Meeting Request) may revoke his, her or its request for a special meeting at any time by written revocation delivered to the secretary.

(3) The secretary shall inform the requesting stockholders of the reasonably estimated cost of preparing and mailing or delivering the notice of the meeting (including the Corporation’s proxy materials). The secretary shall not be required to call a special meeting upon stockholder request and such meeting shall not be held unless, in addition to the documents required by paragraph (2) of this Section 3(b), the secretary receives payment of such reasonably estimated cost prior to the preparation and mailing or delivery of such notice of the meeting.

(4) In the case of any special meeting called by the secretary upon the request of stockholders (a “Stockholder-Requested Meeting”), such meeting shall be held at such place, date and time as may be designated by the Board of Directors; provided, however, that the

2

date of any Stockholder-Requested Meeting shall be not more than 90 days after the record date for such meeting (the “Meeting Record Date”); and provided further that if the Board of Directors fails to designate, within ten days after the date that a valid Special Meeting Request is actually received by the secretary (the “Delivery Date”), a date and time for a Stockholder-Requested Meeting, then such meeting shall be held at 2:00 p.m., local time, on the 90^th day after the Meeting Record Date or, if such 90^th day is not a Business Day (as defined below), on the first preceding Business Day; and provided further that in the event that the Board of Directors fails to designate a place for a Stockholder-Requested Meeting within ten days after the Delivery Date, then such meeting shall be held at the principal executive office of the Corporation. In fixing a date for a Stockholder-Requested Meeting, the Board of Directors may consider such factors as it deems relevant, including, without limitation, the nature of the matters to be considered, the facts and circumstances surrounding any request for the meeting and any plan of the Board of Directors to call an annual meeting or a special meeting. In the case of any Stockholder-Requested Meeting, if the Board of Directors fails to fix a Meeting Record Date that is a date within 30 days after the Delivery Date, then the close of business on the 30^th day after the Delivery Date or, if such 30^th day after the Delivery Date is not a Business Day (as defined below), the first preceding Business Day, shall be the Meeting Record Date. The Board of Directors may revoke the notice for any Stockholder-Requested Meeting in the event that the requesting stockholders fail to comply with the provisions of paragraph (3) of this Section 3(b).

(5) If written revocations of the Special Meeting Request have been delivered to the secretary and the result is that stockholders of record (or their agents duly authorized in writing), as of the Request Record Date, entitled to cast less than the Special Meeting Percentage have delivered, and not revoked, requests for a special meeting on the matter to the secretary: (i) if the notice of meeting has not already been delivered, the secretary shall refrain from delivering the notice of the meeting and send to all requesting stockholders who have not revoked such requests written notice of any revocation of a request for a special meeting on the matter, or (ii) if the notice of meeting has been delivered and if the secretary first sends to all requesting stockholders who have not revoked requests for a special meeting on the matter written notice of any revocation of a request for the special meeting and written notice of the Corporation’s intention to revoke the notice of the meeting or for the chair of the meeting to adjourn the meeting without action on the matter, (A) the secretary may revoke the notice of the meeting at any time before ten days before the commencement of the meeting or (B) the chair of the meeting may call the meeting to order and adjourn the meeting from time to time without acting on the matter. Any request for a special meeting received after a revocation by the secretary of a notice of a meeting shall be considered a request for a new special meeting.

(6) The chair of the board, chief executive officer, president or Board of Directors may appoint regionally or nationally recognized independent inspectors of elections to act as the agent of the Corporation for the purpose of promptly performing a ministerial review of the validity of any purported Special Meeting Request received by the secretary. For the purpose of permitting the inspectors to perform such review, no such purported Special Meeting Request shall be deemed to have been received by the secretary until the earlier of (i) five Business Days after actual receipt by the secretary of such purported request and (ii) such date as the independent inspectors certify to the Corporation that the valid requests received by the secretary represent, as of the Request Record Date, stockholders of record entitled to cast not less than the Special Meeting Percentage. Nothing contained in this paragraph (6) shall in any

3

way be construed to suggest or imply that the Corporation or any stockholder shall not be entitled to contest the validity of any request, whether during or after such five Business Day period, or to take any other action (including, without limitation, the commencement, prosecution or defense of any litigation with respect thereto, and the seeking of injunctive relief in such litigation).

(7) For purposes of these Bylaws, “Business Day” shall mean any day other than a Saturday, a Sunday or a day on which banking institutions in the State of New York are authorized or obligated by law or executive order to close.

Section 4. NOTICE OF MEETINGS. Not less than ten nor more than 90 days before each meeting of stockholders, the secretary shall give to each stockholder entitled to vote at such meeting and to each stockholder not entitled to vote who is entitled to notice of the meeting notice in writing or by electronic transmission stating the time and place of the meeting and, in the case of a special meeting or as otherwise may be required by any statute, the purpose for which the meeting is called, by mail, by presenting it to such stockholder personally, by leaving it at the stockholder’s residence or usual place of business, by electronic transmission or by any other means permitted by Maryland law. If mailed, such notice shall be deemed to be given when deposited in the United States mail addressed to the stockholder at the stockholder’s address as it appears on the records of the Corporation, with postage thereon prepaid. If transmitted electronically, such notice shall be deemed to be given when transmitted to the stockholder by an electronic transmission to any address or number of the stockholder at which the stockholder receives electronic transmissions. The Corporation may give a single notice to all stockholders who share an address, which single notice shall be effective as to any stockholder at such address, unless such stockholder objects to receiving such single notice or revokes a prior consent to receiving such single notice. Failure to give notice of any meeting to one or more stockholders, or any irregularity in such notice, shall not affect the validity of any meeting fixed in accordance with this Article II or the validity of any proceedings at any such meeting. Such notice will also specify the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting.

Subject to Section 11(a) of this Article II, any business of the Corporation may be transacted at an annual meeting of stockholders without being specifically designated in the notice, except such business as is required by any statute to be stated in such notice. No business shall be transacted at a special meeting of stockholders except as specifically designated in the notice. The Corporation may postpone or cancel a meeting of stockholders by making a public announcement (as defined in Section 11(c)(3) of this Article II) of such postponement or cancellation prior to the meeting. Notice of the date, time and place to which the meeting is postponed shall be given not less than ten days prior to such date and otherwise in the manner set forth in this section.

Section 5. ORGANIZATION AND CONDUCT. Every meeting of stockholders shall be conducted by an individual appointed by the Board of Directors to be chair of the meeting or, in the absence of such appointment or appointed individual, by the chair of the board or, in the case of a vacancy in the office or absence of the chair of the board, by one of the following individuals present at the meeting in the following order: the lead independent director, if there is one, the chief executive officer, the president, the vice presidents in their

4

order of rank and, within each rank, in their order of seniority, the secretary, or, in the absence of such officers, a chair chosen by the stockholders by the vote of a majority of the votes cast by stockholders present in person or by proxy. The secretary or, in the case of a vacancy in the office or absence of the secretary, an assistant secretary or an individual appointed by the Board of Directors or the chair of the meeting shall act as secretary. In the event that the secretary presides at a meeting of stockholders, an assistant secretary, or, in the absence of all assistant secretaries, an individual appointed by the Board of Directors or the chair of the meeting, shall record the minutes of the meeting. Even if present at the meeting, the person holding the office named herein may delegate to another person the power to act as chair or secretary of the meeting. The order of business and all other matters of procedure at any meeting of stockholders shall be determined by the chair of the meeting. The chair of the meeting may prescribe such rules, regulations and procedures and take such action as, in the discretion of the chair and without any action by the stockholders, are appropriate for the proper conduct of the meeting, including, without limitation, (a) restricting admission to the time set for the commencement of the meeting; (b) limiting attendance or participation at the meeting to stockholders of record of the Corporation, their duly authorized proxies and such other individuals as the chair of the meeting may determine; (c) recognizing speakers at the meeting and determining when and for how long speakers and any individual speaker may address the meeting; (d) determining when and for how long the polls should be opened and when the polls should be closed and when announcement of the results should be made; (e) maintaining order and security at the meeting; (f) removing any stockholder or any other individual who refuses to comply with meeting procedures, rules or guidelines as set forth by the chair of the meeting; (g) concluding a meeting or recessing or adjourning the meeting (with respect to one or more matters to be considered at such meeting), whether or not a quorum is present, to a later date and time and at a place announced at the meeting; and (h) complying with any state and local laws and regulations concerning safety and security. Unless otherwise determined by the chair of the meeting, meetings of stockholders shall not be required to be held in accordance with any rules of parliamentary procedure.

Section 6. QUORUM. The presence in person or by proxy of stockholders entitled to cast a majority of the votes entitled to be cast at the meeting (without regard to class) shall constitute a quorum at any meeting of the stockholders, except with respect to any matter that, under applicable law or regulatory requirements or the charter of the Corporation (the “Charter”), requires approval by a separate vote of the holders of one or more classes of stock, in which case the presence in person or by proxy of stockholders entitled to cast a majority of the votes entitled to be cast by holders of stock of each such class on such a matter shall constitute a quorum. This section shall not affect any requirement under law or the Charter for the vote necessary for the approval of any matter.

If, however, such quorum is not established at any meeting of the stockholders, the chair of the meeting may adjourn the meeting sine die or from time to time to a date not more than 120 days after the original record date without notice other than announcement at the meeting. At such adjourned meeting at which a quorum shall be present, any business may be transacted which might have been transacted at the meeting as originally notified.

The stockholders present either in person or by proxy, at a meeting which has been duly called and at which a quorum has been established, may continue to transact business until adjournment, notwithstanding the withdrawal from the meeting of enough stockholders to leave fewer than required to establish a quorum.

5

Section 7. VOTING. A majority of all the votes entitled to be cast at a meeting of stockholders duly called and at which a quorum is present shall be sufficient to elect a director. Each share entitles the holder thereof to cast one vote for as many individuals as there are directors to be elected and for whose election the holder of such share is entitled to vote. A majority of the votes cast at a meeting of stockholders duly called and at which a quorum is present shall be sufficient to approve any other matter which may properly come before the meeting, unless a different number or proportion is required by any law or the Charter. Unless otherwise provided by any law or the Charter, each outstanding share, regardless of class, entitles the holder thereof to cast one vote on each matter submitted to a vote at a meeting of stockholders and fractional shares shall be entitled to a proportionate fractional vote on any matter submitted to a vote of stockholders.

Section 8. PROXIES. A stockholder of record may cast votes in person or by proxy executed by the stockholder or by the stockholder’s duly authorized agent in any manner permitted by law. Such proxy or evidence of authorization of such proxy shall be filed with the secretary of the Corporation before or at the meeting. No proxy shall be valid more than eleven months after its date unless otherwise provided in the proxy.

Section 9. VOTING OF STOCK BY CERTAIN HOLDERS. Stock of the Corporation registered in the name of a corporation, limited liability company, partnership, joint venture, trust or other entity, if entitled to be voted, may be voted by the president or a vice president, managing member, manager, general partner or trustee thereof, as the case may be, or a proxy appointed by any of the foregoing individuals, unless some other person who has been appointed to vote such stock pursuant to a bylaw or a resolution of the governing body of such corporation or other entity or agreement of the partners of a partnership presents a certified copy of such bylaw, resolution or agreement, in which case such person may vote such stock. Any trustee or fiduciary, in such capacity, may vote stock registered in such trustee’s or fiduciary’s name, either in person or by proxy.

Shares of stock of the Corporation directly or indirectly owned by it shall not be voted at any meeting and shall not be counted in determining the total number of outstanding shares entitled to be voted at any given time, unless they are held by it in a fiduciary capacity, in which case they may be voted and shall be counted in determining the total number of outstanding shares at any given time.

The Board of Directors may adopt by resolution a procedure by which a stockholder may certify in writing to the Corporation that any shares of stock registered in the name of the stockholder are held for the account of a specified person other than the stockholder. The resolution shall set forth the class of stockholders who may make the certification, the purpose for which the certification may be made, the form of certification and the information to be contained in it; if the certification is with respect to a record date, the time after the record date within which the certification must be received by the Corporation; and any other provisions with respect to the procedure which the Board of Directors considers necessary or desirable. On receipt by the Corporation of such certification, the person specified in the certification shall be regarded as, for the purposes set forth in the certification, the holder of record of the specified stock in place of the stockholder who makes the certification.

Section 10. INSPECTORS. The Board of Directors or the chair of the meeting may appoint, before or at the meeting, one or more inspectors for the meeting and any successor to the inspector. Except as otherwise provided by the chair of the meeting, the inspectors, if any, shall (i) determine the number of shares of stock represented at the meeting, in person or by proxy, and the validity and effect of proxies, (ii) receive and tabulate all votes, ballots or consents, (iii) report such tabulation to the chair of the meeting, (iv) hear and determine all challenges and questions arising in connection with the right to vote, and (v) do such acts as are proper to fairly conduct the election or vote. Each such report shall be in writing and signed by the inspector or by a majority of them if there is more than one inspector acting at such meeting. If there is more than one inspector, the report of a majority shall be the report of the inspectors. The report of the inspector or inspectors on the number of shares represented at the meeting and the results of the voting shall be prima facie evidence thereof.

Section 11. ADVANCE NOTICE OF STOCKHOLDER NOMINEES FOR DIRECTOR AND OTHER STOCKHOLDER PROPOSALS.

(a) Annual Meetings of Stockholders. (1) Nominations of individuals for election to the Board of Directors and the proposal of other business to be considered by the stockholders may be made at an annual meeting of stockholders (i) pursuant to the Corporation’s notice of meeting, (ii) by or at the direction of the Board of Directors or (iii) by any stockholder of the Corporation who was a stockholder of record at the record date set by the Board of Directors for the purpose of determining stockholders entitled to vote at the annual meeting, at the time of giving of notice by the stockholder as provided for in this Section 11(a) and at the time of the annual meeting (and any postponement or adjournment thereof), who is entitled to vote at the meeting in the election of each individual so nominated or on any such other business and who has complied with this Section 11(a).

(2) In addition to complying with any other requirements under all applicable federal and state laws, including the Exchange Act and the rules and regulations thereunder, and the Charter and these Bylaws, for any nomination or other business to be properly brought before an annual meeting by a stockholder pursuant to clause (iii) of paragraph (a)(1) of this Section 11, the stockholder must have given timely notice thereof in writing to the secretary of the Corporation and, in the case of any such other business, such other business must otherwise be a proper matter for action by the stockholders. To be timely, a stockholder’s notice shall set forth all information required under this Section 11 and shall be delivered to the secretary at the principal executive office of the Corporation not earlier than the 150^th day nor later than 5:00 p.m., Eastern Time, on the 120^th day prior to the first anniversary of the date of the proxy statement (as defined in Section 11(c)(3) of this Article II) for the preceding year’s annual meeting; provided, however, that, in the event that the date of the annual meeting is advanced or delayed by more than 30 days from the first anniversary of the date of the preceding year’s annual meeting, in order for notice by the stockholder to be timely, such notice must be so delivered not earlier than the 150^th day prior to the date of such annual meeting and not later than 5:00 p.m., Eastern Time, on the later of the 120^th day prior to the date of such annual meeting, as originally convened, or the tenth day following the day on which public announcement of the

7

date of such meeting is first made; provided further, that, for notice of any nomination or other business to be properly brought before the 2021 annual meeting of stockholders, to be timely, a stockholder’s notice shall set forth all information required under this Section 11, and shall be delivered to the secretary of the Corporation at the principal executive office of the Corporation not earlier than the 120^th day nor later than 5:00 p.m., Eastern Time, on the 90^th day prior to the first anniversary of the date of the proxy statement for the preceding year’s annual meeting. The public announcement of a postponement or adjournment of an annual meeting shall not commence a new time period for the giving of a stockholder’s notice as described above. If a stockholder of record is entitled to vote only for a specific class or category of directors at a meeting (annual or special), such stockholder’s right to nominate one or more individuals for election as a director at the meeting shall be limited to such class or category of directors.

(3) Such stockholder’s notice shall set forth:

(i) as to each individual whom the stockholder proposes to nominate for election or reelection as a director (each, a “Proposed Nominee”),

(A) all information relating to the Proposed Nominee that would be required to be disclosed in connection with the solicitation of proxies for the election of the Proposed Nominee as a director in an election contest (even if an election contest is not involved), or would otherwise be required in connection with such solicitation, in each case pursuant to Regulation 14A (or any successor provision) under the Exchange Act;

(B) a representation that the Proposed Nominee is not and will not be an “interested person” of the Corporation (as defined in the Investment Company Act of 1940, as amended (the “1940 Act”)), and information regarding the Proposed Nominee that will be sufficient, in the discretion of the Board of Directors, for the Corporation to confirm such representation; and

(C) a representation that the Proposed Nominee meets all applicable legal requirements relevant to service as a director, including, but not limited to, the rules adopted by the principal listing exchange (if any) upon which Corporation’s securities are listed, Rule 10A-3 under the Exchange Act (or any successor provision thereto), Article 2-01 of Regulation S-X under the Exchange Act with respect to the Corporation’s independent registered public accounting firm (or any successor provision thereto) and any other criteria established by the 1940 Act related to service as a director of a management investment company or the permitted composition of the board of directors of a management investment company, together with information regarding such Proposed Nominee that will be sufficient, in the discretion of the Board of Directors, to confirm such representation;

(ii) as to any other business that the stockholder proposes to bring before the meeting,

(A) a description of such business (including the text of any resolution proposed for consideration), the stockholder’s reasons for proposing such business at the meeting and any material interest in such business of such stockholder or any Stockholder Associated Person (as defined below), individually or in the aggregate, including any anticipated benefit to the stockholder or the Stockholder Associated Person therefrom; and

(C) whether and the extent to which such stockholder, Proposed Nominee or Stockholder Associated Person, directly or indirectly (through brokers, nominees or otherwise), is subject to or during the last twelve months has engaged in any hedging, derivative or other transaction or series of transactions or entered into any other agreement, arrangement or understanding (including any short interest, any borrowing or lending of securities or any proxy or voting agreement), the effect or intent of which is to (I) manage risk or benefit of changes in the price of (x) Company Securities or (y) any security of any other closed-end investment company (a “Peer Group Company”) for such stockholder, Proposed Nominee or Stockholder Associated Person or (II) increase or decrease the voting power of such stockholder, Proposed Nominee or Stockholder Associated Person in the Corporation or any affiliate thereof (or, as applicable, in any Peer Group Company) disproportionately to such person’s economic interest in the Company Securities (or, as applicable, in any Peer Group Company); and

(D) any substantial interest, direct or indirect (including, without limitation, any existing or prospective commercial, business or contractual relationship with the Corporation), by security holdings or otherwise, of such stockholder, Proposed Nominee or Stockholder Associated Person, in the Corporation or any affiliate thereof, other than an interest arising from the ownership of Company Securities where such stockholder, Proposed Nominee or Stockholder Associated Person receives no extra or special benefit not shared on a pro rata basis by all other holders of the same class or series;

(C) a description of all agreements, arrangements and understandings (whether written or oral) and relationships with respect to the nomination or proposal between or among the stockholder, any Stockholder Associated Person, and any other person or persons (including their names) in connection with the nomination or proposal of such business, and any material interest of such person in such nomination or business, including any anticipated benefit therefrom to such person; and

(4) Such stockholder’s notice shall, with respect to any Proposed Nominee, be accompanied by a written undertaking executed by the Proposed Nominee (i) certifying that such Proposed Nominee (a) is not, and will not become a party to, any agreement, arrangement or understanding with any person or entity other than the Corporation in connection with service or action as a director that has not been disclosed to the Corporation and (b) will serve as a director of the Corporation if elected; and (ii) attaching a completed Proposed Nominee questionnaire (which questionnaire shall be provided by the Corporation, upon request, to the stockholder providing the notice and shall include all information relating to the Proposed Nominee that would be required to be disclosed in connection with the solicitation of proxies for the election of the Proposed Nominee as a director in an election contest (even if an election contest is not involved), or would otherwise be required in connection with such solicitation, in each case pursuant to Regulation 14A (or any successor provision) under the Exchange Act, or would be required pursuant to the rules of any national securities exchange or over-the-counter market on which the Corporation’s securities are listed or traded).

(5) The Proposed Nominee shall, as required by the Board of Directors, sit for an interview with one or more directors or their representatives, which interview may, in the discretion of the Board of Directors be conducted by means of remote communication. Refusal by a Proposed Nominee to participate in such interview will render the nomination ineffective for failure to satisfy the requirements of these Bylaws. The Proposed Nominee shall, as required by the Board of Directors, consent to and cooperate with a background screening conducted by a background screening company selected by the Board of Directors with experience in conducting background screenings of public company directors. Refusal by a Proposed Nominee to cooperate with such a background screening will render the nomination ineffective for failure to satisfy the requirements of these Bylaws.

10

(6) For a stockholder notice to comply with the requirements of this Section 11, each of the requirements of this Section 11 shall be directly and expressly responded to and such stockholder notice must clearly indicate and expressly reference, for all information disclosed in the stockholder notice, the provisions of this Section 11 for which such information is provided.

(7) Notwithstanding anything in this subsection (a) of this Section 11 to the contrary, in the event that the number of directors to be elected to the Board of Directors is increased, and there is no public announcement of such action at least 130 days prior to the first anniversary of the date of the proxy statement (as defined in Section 11(c)(3) of this Article II) for the preceding year’s annual meeting, a stockholder’s notice required by this Section 11(a) shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the secretary at the principal executive office of the Corporation not later than 5:00 p.m., Eastern Time, on the tenth day following the day on which such public announcement is first made by the Corporation.

(8) For purposes of this Section 11, “Stockholder Associated Person” of any stockholder means (i) any person acting in concert with such stockholder, (ii) any beneficial owner of shares of stock of the Corporation owned of record or beneficially by such stockholder (other than a stockholder that is a depositary) and (iii) any person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, such stockholder or such Stockholder Associated Person or is an officer, director, partner, member, employee or agent of such stockholder or such Stockholder Associated Person.

(b) Special Meetings of Stockholders. Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the Corporation’s notice of meeting. Nominations of individuals for election to the Board of Directors may be made at a special meeting of stockholders at which directors are to be elected only (i) by or at the direction of the Board of Directors or (ii) provided that the special meeting has been called in accordance with Section 3 of this Article II for the purpose of electing directors, by any stockholder of the Corporation who is a stockholder of record at the record date set by the Board of Directors for the purpose of determining stockholders entitled to vote at the special meeting, at the time of giving of notice provided for in this Section 11 and at the time of the special meeting (and any postponement or adjournment thereof), who is entitled to vote at the meeting in the election of each individual so nominated and who has complied with the notice procedures set forth in this Section 11. In the event the Corporation calls a special meeting of stockholders for the purpose of electing one or more individuals to the Board of Directors, any such stockholder may nominate an individual or individuals (as the case may be) for election as a director as specified in the Corporation’s notice of meeting, if the stockholder’s notice, containing the information required by paragraphs (a)(3) and (4) of this Section 11 shall be delivered to the secretary at the principal executive office of the Corporation not earlier than the 120^th day prior to such special meeting and not later than 5:00 p.m., Eastern Time, on the later of the 90^th day prior to such special meeting or the tenth day following the day on which public

11

announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting. Any individual nominated in accordance with this paragraph (b) of this Section 11 shall be obligated to comply with paragraph (a)(5) of this Section 11. The public announcement of a postponement or adjournment of a special meeting shall not commence a new time period for the giving of a stockholder’s notice as described above.

(c) General. (1) If information submitted pursuant to this Section 11 by any stockholder proposing a nominee for election as a director or any proposal for other business at a meeting of stockholders shall be inaccurate in any material respect, or if the stockholder otherwise fails to comply with this Section 11, such information, nomination or proposal may be deemed not to have been provided or made in accordance with this Section 11. Any such stockholder shall notify the Corporation of any inaccuracy or change (within two Business Days of becoming aware of such inaccuracy or change) in any such information. Upon written request by the secretary of the Corporation or the Board of Directors, any such stockholder shall provide, within five Business Days of delivery of such request (or such other period as may be specified in such request), (A) written verification, satisfactory, in the discretion of the Board of Directors or any authorized officer of the Corporation, to demonstrate the accuracy of any information submitted by the stockholder pursuant to this Section 11, and (B) a written update of any information (including, if requested by the Corporation, written confirmation by such stockholder that it continues to intend to bring such nomination or other business proposal before the meeting) submitted by the stockholder pursuant to this Section 11 as of an earlier date. If a stockholder fails to provide such written verification or written update within such period, the information as to which written verification or a written update was requested may be deemed not to have been provided in accordance with this Section 11.

(2) Only such individuals who are nominated in accordance with this Section 11 shall be eligible for election by stockholders as directors, and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with this Section 11. The chair of the meeting shall have the power to determine whether a nomination or any other business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with this Section 11. Determinations by the chair of the meeting with respect to compliance of any proposed nomination or business and/or any information submitted to the Corporation by a stockholders or a Proposed Nominee pursuant to this Section 11 shall be final and binding unless determined by a court of competent jurisdiction to have been made in bad faith.

(3) For purposes of this Section 11, (A) “the date of the proxy statement” shall have the same meaning as “the date of the company’s proxy statement released to shareholders” as used in Rule 14a-8(e), as interpreted by the Securities and Exchange Commission from time to time, (B) with respect to the 2021 Annual Meeting of Stockholders, the “preceding year’s annual meeting” shall mean the 2020 annual meeting of shareholders of Pioneer Municipal High Income Advantage Trust, and (C) “Public announcement” shall mean disclosure (i) in a press release reported by the Dow Jones News Service, Associated Press, Business Wire, PR Newswire or other widely circulated news or wire service or (ii) in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to the Exchange Act or the 1940 Act.

12

(4) Notwithstanding the foregoing provisions of this Section 11, and in addition to the requirements thereof, a stockholder shall also have complied with all applicable requirements of state law and of the 1940 Act and the Exchange Act with respect to the acquisition, holding or voting of shares, the disclosure of beneficial ownership of shares or changes therein, the disclosure of any intention to make any proposals with respect to the Corporation or that would affect the management or control of the Corporation, all other required disclosures, and the solicitation of proxies or written consents, or otherwise related to the matters set forth in this Section 11. Nothing in this Section 11 shall be deemed to affect any right of a stockholder to request inclusion of a proposal in, or the right of the Corporation to omit a proposal from, the Corporation’s proxy statement pursuant to Rule 14a-8 (or any successor provision) under the Exchange Act. Nothing in this Section 11 shall require disclosure of revocable proxies received by the stockholder or Stockholder Associated Person pursuant to a solicitation of proxies after the filing of an effective Schedule 14A by such stockholder or Stockholder Associated Person under Section 14(a) of the Exchange Act.

(5) Notwithstanding anything in these Bylaws to the contrary, except as otherwise determined by the chair of the meeting, if the stockholder giving notice as provided for in this Section 11 does not appear in person or by proxy at such annual or special meeting to present each nominee for election as a director or the proposed business, as applicable, such matter shall not be considered at the meeting.

Section 12. VOTING BY BALLOT. Voting on any question or in any election may be viva voce unless the presiding officer shall order or any stockholder shall demand that voting be by ballot.

Section 13. MARYLAND CONTROL SHARE ACQUISITION ACT. Pursuant to a resolution adopted by the Board of Directors in accordance with Section 3-702(c)(4) of the Maryland General Corporation Law (the “MGCL”), the Corporation is subject to Title 3, Subtitle 7 of the MGCL (the “Control Share Act”), which shall apply to any acquisition or proposed acquisition of shares of stock of the Corporation to the extent provided in the Control Share Act. Notwithstanding the foregoing sentence, the Control Share Act shall not apply to the voting rights of the holders of any shares of preferred stock of the Corporation (but only with respect to such shares).

date of any Stockholder-Requested Meeting shall be not more than 90 days after the record date for such meeting (the “Meeting Record Date”); and provided further that if the Board of Directors fails to designate, within ten days after the date that a valid Special Meeting Request is actually received by the secretary (the “Delivery Date”), a date and time for a Stockholder-Requested Meeting, then such meeting shall be held at 2:00 p.m., local time, on the 90^th day after the Meeting Record Date or, if such 90^th day is not a Business Day (as defined below), on the first preceding Business Day; and provided further that in the event that the Board of Directors fails to designate a place for a Stockholder-Requested Meeting within ten days after the Delivery Date, then such meeting shall be held at the principal executive office of the Corporation. In fixing a date for a Stockholder-Requested Meeting, the Board of Directors may consider such factors as it deems relevant, including, without limitation, the nature of the matters to be considered, the facts and circumstances surrounding any request for the meeting and any plan of the Board of Directors to call an annual meeting or a special meeting. In the case of any Stockholder-Requested Meeting, if the Board of Directors fails to fix a Meeting Record Date that is a date within 30 days after the Delivery Date, then the close of business on the 30^th day after the Delivery Date or, if such 30^th day after the Delivery Date is not a Business Day (as defined below), the first preceding Business Day, shall be the Meeting Record Date. The Board of Directors may revoke the notice for any Stockholder-Requested Meeting in the event that the requesting stockholders fail to comply with the provisions of paragraph (3) of this Section 3(b).

(5) If written revocations of the Special Meeting Request have been delivered to the secretary and the result is that stockholders of record (or their agents duly authorized in writing), as of the Request Record Date, entitled to cast less than the Special Meeting Percentage have delivered, and not revoked, requests for a special meeting on the matter to the secretary: (i) if the notice of meeting has not already been delivered, the secretary shall refrain from delivering the notice of the meeting and send to all requesting stockholders who have not revoked such requests written notice of any revocation of a request for a special meeting on the matter, or (ii) if the notice of meeting has been delivered and if the secretary first sends to all requesting stockholders who have not revoked requests for a special meeting on the matter written notice of any revocation of a request for the special meeting and written notice of the Corporation’s intention to revoke the notice of the meeting or for the chair of the meeting to adjourn the meeting without action on the matter, (A) the secretary may revoke the notice of the meeting at any time before ten days before the commencement of the meeting or (B) the chair of the meeting may call the meeting to order and adjourn the meeting from time to time without acting on the matter. Any request for a special meeting received after a revocation by the secretary of a notice of a meeting shall be considered a request for a new special meeting.

(6) The chair of the board, chief executive officer, president or Board of Directors may appoint regionally or nationally recognized independent inspectors of elections to act as the agent of the Corporation for the purpose of promptly performing a ministerial review of the validity of any purported Special Meeting Request received by the secretary. For the purpose of permitting the inspectors to perform such review, no such purported Special Meeting Request shall be deemed to have been received by the secretary until the earlier of (i) five Business Days after actual receipt by the secretary of such purported request and (ii) such date as the independent inspectors certify to the Corporation that the valid requests received by the secretary represent, as of the Request Record Date, stockholders of record entitled to cast not less than the Special Meeting Percentage. Nothing contained in this paragraph (6) shall in any

3

way be construed to suggest or imply that the Corporation or any stockholder shall not be entitled to contest the validity of any request, whether during or after such five Business Day period, or to take any other action (including, without limitation, the commencement, prosecution or defense of any litigation with respect thereto, and the seeking of injunctive relief in such litigation).

(7) For purposes of these Bylaws, “Business Day” shall mean any day other than a Saturday, a Sunday or a day on which banking institutions in the State of New York are authorized or obligated by law or executive order to close.

Section 4. NOTICE OF MEETINGS. Not less than ten nor more than 90 days before each meeting of stockholders, the secretary shall give to each stockholder entitled to vote at such meeting and to each stockholder not entitled to vote who is entitled to notice of the meeting notice in writing or by electronic transmission stating the time and place of the meeting and, in the case of a special meeting or as otherwise may be required by any statute, the purpose for which the meeting is called, by mail, by presenting it to such stockholder personally, by leaving it at the stockholder’s residence or usual place of business, by electronic transmission or by any other means permitted by Maryland law. If mailed, such notice shall be deemed to be given when deposited in the United States mail addressed to the stockholder at the stockholder’s address as it appears on the records of the Corporation, with postage thereon prepaid. If transmitted electronically, such notice shall be deemed to be given when transmitted to the stockholder by an electronic transmission to any address or number of the stockholder at which the stockholder receives electronic transmissions. The Corporation may give a single notice to all stockholders who share an address, which single notice shall be effective as to any stockholder at such address, unless such stockholder objects to receiving such single notice or revokes a prior consent to receiving such single notice. Failure to give notice of any meeting to one or more stockholders, or any irregularity in such notice, shall not affect the validity of any meeting fixed in accordance with this Article II or the validity of any proceedings at any such meeting. Such notice will also specify the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting.

Subject to Section 11(a) of this Article II, any business of the Corporation may be transacted at an annual meeting of stockholders without being specifically designated in the notice, except such business as is required by any statute to be stated in such notice. No business shall be transacted at a special meeting of stockholders except as specifically designated in the notice. The Corporation may postpone or cancel a meeting of stockholders by making a public announcement (as defined in Section 11(c)(3) of this Article II) of such postponement or cancellation prior to the meeting. Notice of the date, time and place to which the meeting is postponed shall be given not less than ten days prior to such date and otherwise in the manner set forth in this section.

Section 5. ORGANIZATION AND CONDUCT. Every meeting of stockholders shall be conducted by an individual appointed by the Board of Directors to be chair of the meeting or, in the absence of such appointment or appointed individual, by the chair of the board or, in the case of a vacancy in the office or absence of the chair of the board, by one of the following individuals present at the meeting in the following order: the lead independent director, if there is one, the chief executive officer, the president, the vice presidents in their

4

order of rank and, within each rank, in their order of seniority, the secretary, or, in the absence of such officers, a chair chosen by the stockholders by the vote of a majority of the votes cast by stockholders present in person or by proxy. The secretary or, in the case of a vacancy in the office or absence of the secretary, an assistant secretary or an individual appointed by the Board of Directors or the chair of the meeting shall act as secretary. In the event that the secretary presides at a meeting of stockholders, an assistant secretary, or, in the absence of all assistant secretaries, an individual appointed by the Board of Directors or the chair of the meeting, shall record the minutes of the meeting. Even if present at the meeting, the person holding the office named herein may delegate to another person the power to act as chair or secretary of the meeting. The order of business and all other matters of procedure at any meeting of stockholders shall be determined by the chair of the meeting. The chair of the meeting may prescribe such rules, regulations and procedures and take such action as, in the discretion of the chair and without any action by the stockholders, are appropriate for the proper conduct of the meeting, including, without limitation, (a) restricting admission to the time set for the commencement of the meeting; (b) limiting attendance or participation at the meeting to stockholders of record of the Corporation, their duly authorized proxies and such other individuals as the chair of the meeting may determine; (c) recognizing speakers at the meeting and determining when and for how long speakers and any individual speaker may address the meeting; (d) determining when and for how long the polls should be opened and when the polls should be closed and when announcement of the results should be made; (e) maintaining order and security at the meeting; (f) removing any stockholder or any other individual who refuses to comply with meeting procedures, rules or guidelines as set forth by the chair of the meeting; (g) concluding a meeting or recessing or adjourning the meeting (with respect to one or more matters to be considered at such meeting), whether or not a quorum is present, to a later date and time and at a place announced at the meeting; and (h) complying with any state and local laws and regulations concerning safety and security. Unless otherwise determined by the chair of the meeting, meetings of stockholders shall not be required to be held in accordance with any rules of parliamentary procedure.

Section 6. QUORUM. The presence in person or by proxy of stockholders entitled to cast a majority of the votes entitled to be cast at the meeting (without regard to class) shall constitute a quorum at any meeting of the stockholders, except with respect to any matter that, under applicable law or regulatory requirements or the charter of the Corporation (the “Charter”), requires approval by a separate vote of the holders of one or more classes of stock, in which case the presence in person or by proxy of stockholders entitled to cast a majority of the votes entitled to be cast by holders of stock of each such class on such a matter shall constitute a quorum. This section shall not affect any requirement under law or the Charter for the vote necessary for the approval of any matter.

If, however, such quorum is not established at any meeting of the stockholders, the chair of the meeting may adjourn the meeting sine die or from time to time to a date not more than 120 days after the original record date without notice other than announcement at the meeting. At such adjourned meeting at which a quorum shall be present, any business may be transacted which might have been transacted at the meeting as originally notified.

The stockholders present either in person or by proxy, at a meeting which has been duly called and at which a quorum has been established, may continue to transact business until adjournment, notwithstanding the withdrawal from the meeting of enough stockholders to leave fewer than required to establish a quorum.

5

Section 7. VOTING. A majority of all the votes entitled to be cast at a meeting of stockholders duly called and at which a quorum is present shall be sufficient to elect a director. Each share entitles the holder thereof to cast one vote for as many individuals as there are directors to be elected and for whose election the holder of such share is entitled to vote. A majority of the votes cast at a meeting of stockholders duly called and at which a quorum is present shall be sufficient to approve any other matter which may properly come before the meeting, unless a different number or proportion is required by any law or the Charter. Unless otherwise provided by any law or the Charter, each outstanding share, regardless of class, entitles the holder thereof to cast one vote on each matter submitted to a vote at a meeting of stockholders and fractional shares shall be entitled to a proportionate fractional vote on any matter submitted to a vote of stockholders.

Section 8. PROXIES. A stockholder of record may cast votes in person or by proxy executed by the stockholder or by the stockholder’s duly authorized agent in any manner permitted by law. Such proxy or evidence of authorization of such proxy shall be filed with the secretary of the Corporation before or at the meeting. No proxy shall be valid more than eleven months after its date unless otherwise provided in the proxy.

Section 9. VOTING OF STOCK BY CERTAIN HOLDERS. Stock of the Corporation registered in the name of a corporation, limited liability company, partnership, joint venture, trust or other entity, if entitled to be voted, may be voted by the president or a vice president, managing member, manager, general partner or trustee thereof, as the case may be, or a proxy appointed by any of the foregoing individuals, unless some other person who has been appointed to vote such stock pursuant to a bylaw or a resolution of the governing body of such corporation or other entity or agreement of the partners of a partnership presents a certified copy of such bylaw, resolution or agreement, in which case such person may vote such stock. Any trustee or fiduciary, in such capacity, may vote stock registered in such trustee’s or fiduciary’s name, either in person or by proxy.

Shares of stock of the Corporation directly or indirectly owned by it shall not be voted at any meeting and shall not be counted in determining the total number of outstanding shares entitled to be voted at any given time, unless they are held by it in a fiduciary capacity, in which case they may be voted and shall be counted in determining the total number of outstanding shares at any given time.

The Board of Directors may adopt by resolution a procedure by which a stockholder may certify in writing to the Corporation that any shares of stock registered in the name of the stockholder are held for the account of a specified person other than the stockholder. The resolution shall set forth the class of stockholders who may make the certification, the purpose for which the certification may be made, the form of certification and the information to be contained in it; if the certification is with respect to a record date, the time after the record date within which the certification must be received by the Corporation; and any other provisions with respect to the procedure which the Board of Directors considers necessary or desirable. On receipt by the Corporation of such certification, the person specified in the certification shall be regarded as, for the purposes set forth in the certification, the holder of record of the specified stock in place of the stockholder who makes the certification.

6

Section 10. INSPECTORS. The Board of Directors or the chair of the meeting may appoint, before or at the meeting, one or more inspectors for the meeting and any successor to the inspector. Except as otherwise provided by the chair of the meeting, the inspectors, if any, shall (i) determine the number of shares of stock represented at the meeting, in person or by proxy, and the validity and effect of proxies, (ii) receive and tabulate all votes, ballots or consents, (iii) report such tabulation to the chair of the meeting, (iv) hear and determine all challenges and questions arising in connection with the right to vote, and (v) do such acts as are proper to fairly conduct the election or vote. Each such report shall be in writing and signed by the inspector or by a majority of them if there is more than one inspector acting at such meeting. If there is more than one inspector, the report of a majority shall be the report of the inspectors. The report of the inspector or inspectors on the number of shares represented at the meeting and the results of the voting shall be prima facie evidence thereof.

Section 11. ADVANCE NOTICE OF STOCKHOLDER NOMINEES FOR DIRECTOR AND OTHER STOCKHOLDER PROPOSALS.

(a) Annual Meetings of Stockholders. (1) Nominations of individuals for election to the Board of Directors and the proposal of other business to be considered by the stockholders may be made at an annual meeting of stockholders (i) pursuant to the Corporation’s notice of meeting, (ii) by or at the direction of the Board of Directors or (iii) by any stockholder of the Corporation who was a stockholder of record at the record date set by the Board of Directors for the purpose of determining stockholders entitled to vote at the annual meeting, at the time of giving of notice by the stockholder as provided for in this Section 11(a) and at the time of the annual meeting (and any postponement or adjournment thereof), who is entitled to vote at the meeting in the election of each individual so nominated or on any such other business and who has complied with this Section 11(a).

(2) In addition to complying with any other requirements under all applicable federal and state laws, including the Exchange Act and the rules and regulations thereunder, and the Charter and these Bylaws, for any nomination or other business to be properly brought before an annual meeting by a stockholder pursuant to clause (iii) of paragraph (a)(1) of this Section 11, the stockholder must have given timely notice thereof in writing to the secretary of the Corporation and, in the case of any such other business, such other business must otherwise be a proper matter for action by the stockholders. To be timely, a stockholder’s notice shall set forth all information required under this Section 11 and shall be delivered to the secretary at the principal executive office of the Corporation not earlier than the 150^th day nor later than 5:00 p.m., Eastern Time, on the 120^th day prior to the first anniversary of the date of the proxy statement (as defined in Section 11(c)(3) of this Article II) for the preceding year’s annual meeting; provided, however, that, in the event that the date of the annual meeting is advanced or delayed by more than 30 days from the first anniversary of the date of the preceding year’s annual meeting, in order for notice by the stockholder to be timely, such notice must be so delivered not earlier than the 150^th day prior to the date of such annual meeting and not later than 5:00 p.m., Eastern Time, on the later of the 120^th day prior to the date of such annual meeting, as originally convened, or the tenth day following the day on which public announcement of the

7

date of such meeting is first made; provided further, that, for notice of any nomination or other business to be properly brought before the 2021 annual meeting of stockholders, to be timely, a stockholder’s notice shall set forth all information required under this Section 11, and shall be delivered to the secretary of the Corporation at the principal executive office of the Corporation not earlier than the 120^th day nor later than 5:00 p.m., Eastern Time, on the 90^th day prior to the first anniversary of the date of the proxy statement for the preceding year’s annual meeting. The public announcement of a postponement or adjournment of an annual meeting shall not commence a new time period for the giving of a stockholder’s notice as described above. If a stockholder of record is entitled to vote only for a specific class or category of directors at a meeting (annual or special), such stockholder’s right to nominate one or more individuals for election as a director at the meeting shall be limited to such class or category of directors.

(3) Such stockholder’s notice shall set forth:

(i) as to each individual whom the stockholder proposes to nominate for election or reelection as a director (each, a “Proposed Nominee”),

(A) all information relating to the Proposed Nominee that would be required to be disclosed in connection with the solicitation of proxies for the election of the Proposed Nominee as a director in an election contest (even if an election contest is not involved), or would otherwise be required in connection with such solicitation, in each case pursuant to Regulation 14A (or any successor provision) under the Exchange Act;

(B) a representation that the Proposed Nominee is not and will not be an “interested person” of the Corporation (as defined in the Investment Company Act of 1940, as amended (the “1940 Act”)), and information regarding the Proposed Nominee that will be sufficient, in the discretion of the Board of Directors, for the Corporation to confirm such representation; and

(C) a representation that the Proposed Nominee meets all applicable legal requirements relevant to service as a director, including, but not limited to, the rules adopted by the principal listing exchange (if any) upon which Corporation’s securities are listed, Rule 10A-3 under the Exchange Act (or any successor provision thereto), Article 2-01 of Regulation S-X under the Exchange Act with respect to the Corporation’s independent registered public accounting firm (or any successor provision thereto) and any other criteria established by the 1940 Act related to service as a director of a management investment company or the permitted composition of the board of directors of a management investment company, together with information regarding such Proposed Nominee that will be sufficient, in the discretion of the Board of Directors, to confirm such representation;

(ii) as to any other business that the stockholder proposes to bring before the meeting,

(A) a description of such business (including the text of any resolution proposed for consideration), the stockholder’s reasons for proposing such business at the meeting and any material interest in such business of such stockholder or any Stockholder Associated Person (as defined below), individually or in the aggregate, including any anticipated benefit to the stockholder or the Stockholder Associated Person therefrom; and

8

(B) whether the stockholder has received any financial assistance, funding or other consideration from any Stockholder Associated Person in respect of the proposal and the details thereof;

(iii) as to the stockholder giving the notice, any Proposed Nominee and any Stockholder Associated Person,

(B) the nominee holder for, and number of, any Company Securities owned beneficially but not of record by such stockholder, Proposed Nominee or Stockholder Associated Person;

(C) whether and the extent to which such stockholder, Proposed Nominee or Stockholder Associated Person, directly or indirectly (through brokers, nominees or otherwise), is subject to or during the last twelve months has engaged in any hedging, derivative or other transaction or series of transactions or entered into any other agreement, arrangement or understanding (including any short interest, any borrowing or lending of securities or any proxy or voting agreement), the effect or intent of which is to (I) manage risk or benefit of changes in the price of (x) Company Securities or (y) any security of any other closed-end investment company (a “Peer Group Company”) for such stockholder, Proposed Nominee or Stockholder Associated Person or (II) increase or decrease the voting power of such stockholder, Proposed Nominee or Stockholder Associated Person in the Corporation or any affiliate thereof (or, as applicable, in any Peer Group Company) disproportionately to such person’s economic interest in the Company Securities (or, as applicable, in any Peer Group Company); and

(D) any substantial interest, direct or indirect (including, without limitation, any existing or prospective commercial, business or contractual relationship with the Corporation), by security holdings or otherwise, of such stockholder, Proposed Nominee or Stockholder Associated Person, in the Corporation or any affiliate thereof, other than an interest arising from the ownership of Company Securities where such stockholder, Proposed Nominee or Stockholder Associated Person receives no extra or special benefit not shared on a pro rata basis by all other holders of the same class or series;

(C) a description of all agreements, arrangements and understandings (whether written or oral) and relationships with respect to the nomination or proposal between or among the stockholder, any Stockholder Associated Person, and any other person or persons (including their names) in connection with the nomination or proposal of such business, and any material interest of such person in such nomination or business, including any anticipated benefit therefrom to such person; and

(4) Such stockholder’s notice shall, with respect to any Proposed Nominee, be accompanied by a written undertaking executed by the Proposed Nominee (i) certifying that such Proposed Nominee (a) is not, and will not become a party to, any agreement, arrangement or understanding with any person or entity other than the Corporation in connection with service or action as a director that has not been disclosed to the Corporation and (b) will serve as a director of the Corporation if elected; and (ii) attaching a completed Proposed Nominee questionnaire (which questionnaire shall be provided by the Corporation, upon request, to the stockholder providing the notice and shall include all information relating to the Proposed Nominee that would be required to be disclosed in connection with the solicitation of proxies for the election of the Proposed Nominee as a director in an election contest (even if an election contest is not involved), or would otherwise be required in connection with such solicitation, in each case pursuant to Regulation 14A (or any successor provision) under the Exchange Act, or would be required pursuant to the rules of any national securities exchange or over-the-counter market on which the Corporation’s securities are listed or traded).

(5) The Proposed Nominee shall, as required by the Board of Directors, sit for an interview with one or more directors or their representatives, which interview may, in the discretion of the Board of Directors be conducted by means of remote communication. Refusal by a Proposed Nominee to participate in such interview will render the nomination ineffective for failure to satisfy the requirements of these Bylaws. The Proposed Nominee shall, as required by the Board of Directors, consent to and cooperate with a background screening conducted by a background screening company selected by the Board of Directors with experience in conducting background screenings of public company directors. Refusal by a Proposed Nominee to cooperate with such a background screening will render the nomination ineffective for failure to satisfy the requirements of these Bylaws.

10

(6) For a stockholder notice to comply with the requirements of this Section 11, each of the requirements of this Section 11 shall be directly and expressly responded to and such stockholder notice must clearly indicate and expressly reference, for all information disclosed in the stockholder notice, the provisions of this Section 11 for which such information is provided.

(7) Notwithstanding anything in this subsection (a) of this Section 11 to the contrary, in the event that the number of directors to be elected to the Board of Directors is increased, and there is no public announcement of such action at least 130 days prior to the first anniversary of the date of the proxy statement (as defined in Section 11(c)(3) of this Article II) for the preceding year’s annual meeting, a stockholder’s notice required by this Section 11(a) shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the secretary at the principal executive office of the Corporation not later than 5:00 p.m., Eastern Time, on the tenth day following the day on which such public announcement is first made by the Corporation.

(8) For purposes of this Section 11, “Stockholder Associated Person” of any stockholder means (i) any person acting in concert with such stockholder, (ii) any beneficial owner of shares of stock of the Corporation owned of record or beneficially by such stockholder (other than a stockholder that is a depositary) and (iii) any person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, such stockholder or such Stockholder Associated Person or is an officer, director, partner, member, employee or agent of such stockholder or such Stockholder Associated Person.

(b) Special Meetings of Stockholders. Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the Corporation’s notice of meeting. Nominations of individuals for election to the Board of Directors may be made at a special meeting of stockholders at which directors are to be elected only (i) by or at the direction of the Board of Directors or (ii) provided that the special meeting has been called in accordance with Section 3 of this Article II for the purpose of electing directors, by any stockholder of the Corporation who is a stockholder of record at the record date set by the Board of Directors for the purpose of determining stockholders entitled to vote at the special meeting, at the time of giving of notice provided for in this Section 11 and at the time of the special meeting (and any postponement or adjournment thereof), who is entitled to vote at the meeting in the election of each individual so nominated and who has complied with the notice procedures set forth in this Section 11. In the event the Corporation calls a special meeting of stockholders for the purpose of electing one or more individuals to the Board of Directors, any such stockholder may nominate an individual or individuals (as the case may be) for election as a director as specified in the Corporation’s notice of meeting, if the stockholder’s notice, containing the information required by paragraphs (a)(3) and (4) of this Section 11 shall be delivered to the secretary at the principal executive office of the Corporation not earlier than the 120^th day prior to such special meeting and not later than 5:00 p.m., Eastern Time, on the later of the 90^th day prior to such special meeting or the tenth day following the day on which public

11

announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting. Any individual nominated in accordance with this paragraph (b) of this Section 11 shall be obligated to comply with paragraph (a)(5) of this Section 11. The public announcement of a postponement or adjournment of a special meeting shall not commence a new time period for the giving of a stockholder’s notice as described above.

(c) General. (1) If information submitted pursuant to this Section 11 by any stockholder proposing a nominee for election as a director or any proposal for other business at a meeting of stockholders shall be inaccurate in any material respect, or if the stockholder otherwise fails to comply with this Section 11, such information, nomination or proposal may be deemed not to have been provided or made in accordance with this Section 11. Any such stockholder shall notify the Corporation of any inaccuracy or change (within two Business Days of becoming aware of such inaccuracy or change) in any such information. Upon written request by the secretary of the Corporation or the Board of Directors, any such stockholder shall provide, within five Business Days of delivery of such request (or such other period as may be specified in such request), (A) written verification, satisfactory, in the discretion of the Board of Directors or any authorized officer of the Corporation, to demonstrate the accuracy of any information submitted by the stockholder pursuant to this Section 11, and (B) a written update of any information (including, if requested by the Corporation, written confirmation by such stockholder that it continues to intend to bring such nomination or other business proposal before the meeting) submitted by the stockholder pursuant to this Section 11 as of an earlier date. If a stockholder fails to provide such written verification or written update within such period, the information as to which written verification or a written update was requested may be deemed not to have been provided in accordance with this Section 11.

(2) Only such individuals who are nominated in accordance with this Section 11 shall be eligible for election by stockholders as directors, and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with this Section 11. The chair of the meeting shall have the power to determine whether a nomination or any other business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with this Section 11. Determinations by the chair of the meeting with respect to compliance of any proposed nomination or business and/or any information submitted to the Corporation by a stockholders or a Proposed Nominee pursuant to this Section 11 shall be final and binding unless determined by a court of competent jurisdiction to have been made in bad faith.

(3) For purposes of this Section 11, (A) “the date of the proxy statement” shall have the same meaning as “the date of the company’s proxy statement released to shareholders” as used in Rule 14a-8(e), as interpreted by the Securities and Exchange Commission from time to time, (B) with respect to the 2021 Annual Meeting of Stockholders, the “preceding year’s annual meeting” shall mean the 2020 annual meeting of shareholders of Pioneer High Income Trust, and (C) “Public announcement” shall mean disclosure (i) in a press release reported by the Dow Jones News Service, Associated Press, Business Wire, PR Newswire or other widely circulated news or wire service or (ii) in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to the Exchange Act or the 1940 Act.

12

(4) Notwithstanding the foregoing provisions of this Section 11, and in addition to the requirements thereof, a stockholder shall also have complied with all applicable requirements of state law and of the 1940 Act and the Exchange Act with respect to the acquisition, holding or voting of shares, the disclosure of beneficial ownership of shares or changes therein, the disclosure of any intention to make any proposals with respect to the Corporation or that would affect the management or control of the Corporation, all other required disclosures, and the solicitation of proxies or written consents, or otherwise related to the matters set forth in this Section 11. Nothing in this Section 11 shall be deemed to affect any right of a stockholder to request inclusion of a proposal in, or the right of the Corporation to omit a proposal from, the Corporation’s proxy statement pursuant to Rule 14a-8 (or any successor provision) under the Exchange Act. Nothing in this Section 11 shall require disclosure of revocable proxies received by the stockholder or Stockholder Associated Person pursuant to a solicitation of proxies after the filing of an effective Schedule 14A by such stockholder or Stockholder Associated Person under Section 14(a) of the Exchange Act.

(5) Notwithstanding anything in these Bylaws to the contrary, except as otherwise determined by the chair of the meeting, if the stockholder giving notice as provided for in this Section 11 does not appear in person or by proxy at such annual or special meeting to present each nominee for election as a director or the proposed business, as applicable, such matter shall not be considered at the meeting.

Section 12. VOTING BY BALLOT. Voting on any question or in any election may be viva voce unless the presiding officer shall order or any stockholder shall demand that voting be by ballot.
