The Maximum Rate for shares of a Series of VRDP Shares will depend on the long-term rating assigned to such Series of VRDP Shares, the length of the Rate Period and whether or not the Trust has given notification to the Remarketing Agent and the Tender and Paying Agent prior to the Applicable Rate Determination for the Rate Period pursuant to Section 6 of Part II hereto that any ordinary income or capital gains will be included in the dividend on shares of a Series of VRDP Shares for that Rate Period. The Applicable Percentage of the Applicable Base Rate is as follows:

Long-Term* Rating		Applicable Percentage of Applicable Base Rate— No Notification
Fitch	Moody's
AA- to AAA	Aa3 to Aaa	100%
BBB- to A+	Baa3 to A1	110%

provided, however, that in the event the Trust has given notification prior to the Applicable Rate Determination for the Rate Period pursuant to Section 6 of Part II hereof that any ordinary income and capital gains will be included in the dividend on shares of the Series of VRDP Shares for that Rate Period, the Applicable Percentage in the foregoing table shall be divided by the quantity one (1) minus (i) the maximum marginal regular federal personal income tax rate applicable to ordinary income or net capital gains (as applicable), each expressed as a decimal applicable to ordinary income or net capital gains (as applicable), or (ii) the maximum marginal regular federal corporate income tax rate applicable to ordinary income or net capital gains (as applicable), each expressed as a decimal applicable to ordinary income or net capital gains (as applicable), whichever is greater and determined on a weighted average basis in respect of the relative amounts of ordinary income and net capital gains.

The Applicable Percentage as so determined and the Applicable Spread may be subject to upward (and if previously adjusted upward, subsequent downward) adjustment as provided in the VRDP Shares Remarketing Agreement, with the prior written consent of the Liquidity Provider and after consultation with the Remarketing Agent; provided, that, notwithstanding any provision to the contrary in the VRDP Shares Remarketing Agreement, the Maximum Rate is equal to or higher than the rates determined as set forth above, and immediately following any such increase, the Trust would be in compliance with the Minimum VRDP Shares Asset Coverage and the VRDP Shares Basic Maintenance Amount in the Rating Agency Guidelines.

A Maximum Rate in effect in respect of a Failed Remarketing Condition will continue to be the Applicable Rate (i) until the first (1st) day of the next succeeding Subsequent Rate Period after a Failed Remarketing Condition no longer exists in the case of a Minimum Rate Period or a Special Rate Period of twenty-eight (28) Rate Period Days or fewer, and (ii) until the first (1st) day of the next succeeding Dividend Period after a Failed Remarketing Condition no longer exists in the case of a Special Rate Period of greater than twenty-eight (28) Rate Period Days.

Notwithstanding any provision to the contrary in the VRDP Shares Remarketing Agreement, in no event shall the Maximum Rate exceed 15%; provided, however, that in the event the Trust has given notification prior to the Applicable Rate Determination for the Rate Period pursuant to Section 6 of Part II hereof that any ordinary income or capital gains will be included in the dividend on shares of the Series of VRDP Shares for that Rate Period, the Maximum Rate shall not exceed 15% divided by the quantity one (1) minus (i) the maximum marginal regular federal personal income tax rate applicable to ordinary income or net capital gains (as applicable), each expressed as a decimal applicable to ordinary income or net capital gains (as applicable), or (ii) the maximum marginal regular federal corporate income tax rate applicable to ordinary income or net capital gains (as applicable), each expressed as a decimal applicable to ordinary income or net capital gains (as applicable), whichever is greater and determined on a weighted average basis in respect of the relative amounts of ordinary income and net capital gains.

(C) if any Failure to Deposit shall have occurred with respect to shares of such Series during any Dividend Period thereof, but, prior to 12:00 noon, New York City time, on the third (3rd) Business Day next succeeding the date on which such Failure to Deposit occurred, such Failure to Deposit shall have been cured in accordance with paragraph (f) of this Section 2, and the Trust shall have paid to the Tender and Paying Agent as a late charge ("Late Charge") daily supplemental dividends equal in the aggregate to the sum of (1) if such Failure to Deposit consisted of the failure to timely pay to the Tender and Paying Agent the full amount of dividends with respect to any Dividend Period of the shares of such Series, an amount computed by multiplying (x) the Applicable Rate for the Rate Period during which such Failure to Deposit occurs on the Dividend Payment Date for such Dividend Period plus 2.00% by (y) a fraction, the numerator of which shall be the number of days for which such Failure to Deposit has not been cured in accordance with paragraph (f) of this Section 2 (including the day such Failure to Deposit occurs and excluding the day such Failure to Deposit is cured) and the denominator of which shall be 360, and applying the rate obtained against the aggregate Liquidation Preference of the Outstanding shares of such Series (with the amount for each individual day that such Failure to Deposit occurs or continues uncured being declared as a supplemental dividend on that day) and (2) if such Failure to Deposit consisted of the failure to timely pay to the Tender and Paying Agent the Redemption Price of the shares, if any, of such Series for which Notice of Redemption has been provided by the Trust pursuant to paragraph (c) of Section 10 of Part I of this Certificate of Designation, an amount computed by multiplying, (x) for the Rate Period during which such Failure to Deposit occurs on the Redemption Date, the Applicable Rate plus 2.00% by (y) a fraction, the numerator of which shall be the number of days for which such Failure to Deposit is not cured in accordance with paragraph (f) of this Section 2 (including the day such Failure to Deposit occurs and excluding the day such Failure to Deposit is cured) and the denominator of which shall be 360, and applying the rate obtained against the aggregate Liquidation Preference of the Outstanding shares of such Series to be redeemed (with the amount for each individual day that such Failure to Deposit occurs or continues uncured being declared as a supplemental dividend on that day), and if a Rate Determination Date occurs on the date on which such Failure to Deposit occurred or on either of the two (2) Business Days succeeding that date, and the Failure to Deposit has not been cured on such Rate Determination Date in accordance with paragraph (f) of this Section 2, no Applicable Rate Determination will be held in respect of shares of such Series for the Subsequent Rate Period relating to such Rate Determination Date and the dividend rate for shares of such Series for such Subsequent Rate Period will be the Maximum Rate for shares of such Series on the Rate Determination Date for such Subsequent Rate Period; or

(D) if any Failure to Deposit shall have occurred with respect to shares of such Series during any Dividend Period thereof, and, prior to 12:00 noon, New York City time, on the third (3rd) Business Day next succeeding the date on which such Failure to Deposit occurred, such Failure to Deposit shall not have been cured in accordance with paragraph (f) of this Section 2 or the Trust shall not have paid the applicable Late Charge to the Tender and Paying Agent, no Applicable Rate Determination will occur in respect of shares of such Series for the first Subsequent Rate Period thereof thereafter (or for any Subsequent Rate Period thereof thereafter to and including the Subsequent Rate Period during which (1) such Failure to Deposit is cured in accordance with paragraph (f) of this Section 2 and (2) the Trust pays the applicable Late Charge to the Tender and Paying Agent, in each case no later than 12:00 noon, New York City time, on the fourth (4th) Business Day prior to the end of such Subsequent Rate Period), and the dividend rate for shares of such Series for each such Subsequent Rate Period shall be a rate per annum equal to the Maximum Rate for shares of such Series on the Rate Determination Date for such Subsequent Rate Period (but with the prevailing rating for shares of such Series, for purposes of determining such Maximum Rate, being deemed to be "below 'BBB-'").

Each dividend rate determined in accordance with this paragraph (e)(i) of Section 2 of Part I of this Certificate of Designation shall be an "Applicable Rate."

(ii)

Calculation of Dividends. The amount of dividends per share payable on shares of a Series of VRDP Shares on any Dividend Payment Date shall equal the sum of the dividends accumulated but not yet paid for each Rate Period (or part thereof) in the related Dividend Period or Dividend Periods. The amount of dividends accumulated for each such Rate Period (or part thereof) shall be computed by multiplying the Applicable Rate in effect for shares of such Series for such Rate Period (or part thereof) by a fraction, the numerator of which shall be the number of days in such Rate Period (or part thereof) and the denominator of which shall be the actual number of days in the year (365 or 366), and multiplying such product by $100,000.

(f) Curing a Failure to Deposit

. A Failure to Deposit with respect to shares of a Series of VRDP Shares shall have been cured (if such Failure to Deposit is not solely due to the willful failure of the Trust to make the required payment to the Tender and Paying Agent) with respect to any Dividend Period of shares of such Series if, within the respective time periods described in paragraph (e)(i) of this Section 2, the Trust shall have paid to the Tender and Paying Agent (A) all accumulated but unpaid dividends on shares of such Series and (B) without duplication, the Redemption Price for shares, if any, of such Series for which Notice of Redemption has been provided by the Trust pursuant to paragraph (c) of Section 10 of Part I of this Certificate of Designation; provided, however, that the foregoing clause (B) shall not apply to the Trust's failure to pay the Redemption Price in respect of shares of a Series of VRDP Shares when the related Notice of Redemption provides that redemption of such shares is subject to one or more conditions precedent and any such condition precedent shall not have been satisfied at the time or times and in the manner specified in such Notice of Redemption.

(g) Dividend Payments by Trust to Tender and Paying Agent

. In connection with each Dividend Payment Date for shares of a Series of VRDP Shares, the Trust shall pay to the Tender and Paying Agent, not later than 12:00 noon, New York City time, on the earlier of (A) the third (3rd) Business Day next succeeding the Rate Determination Date immediately preceding the Dividend Payment Date for such Series and (B) the Business Day immediately preceding the Dividend Payment Date for such Series (or as otherwise provided for and in connection with designation of a Special Rate Period), an aggregate amount of Deposit Securities equal to the dividends to be paid to all Holders of shares of such Series on such Dividend Payment Date as determined in accordance with Section 2(e)(ii) of Part I of this Certificate of Designation, or as otherwise provided for and in connection with designation of a Special Rate Period. If an aggregate amount of funds equal to the dividends to be paid to all Holders of shares of such Series on such Dividend Payment Date are not available in New York, New York by 12:00 noon, New York City time, on the Business Day immediately preceding such Dividend Payment Date, the Tender and Paying Agent will notify the Liquidity Provider by Electronic Means of such fact prior to the close of business on such day.

(h) Tender and Paying Agent as Trustee of Dividend Payments by Trust

. All Deposit Securities paid to the Tender and Paying Agent for the payment of dividends (or for the payment of any Late Charge) shall be held in trust for the payment of such dividends (and any such Late Charge) by the Tender and Paying Agent for the benefit of the Holders specified in paragraph (i) of this Section 2. The Tender and Paying Agent shall notify the Trust by Electronic Means of the amount of any funds deposited with the Tender and Paying Agent by the Trust for any reason under the Tender and Paying Agent Agreement, including for the payment of dividends or the redemption of shares of a Series of VRDP Shares (or any Late Charge), that remain with the Tender and Paying Agent after ninety (90) days from the date of such deposit and such amount shall, to the extent permitted by law, be repaid to the Trust by the Tender and Paying Agent upon request by Electronic Means of the Trust.

(i) Dividends Paid to Holders

. Each dividend on shares of a Series of VRDP Shares shall be declared daily to the Holders thereof at the close of business on each such day and paid on each Dividend Payment Date to the Holders thereof at the close of business on the day immediately preceding such Dividend Payment Date. In connection with any transfer of shares of a Series of VRDP Shares, the transferor as Beneficial Owner of such shares shall be deemed to have agreed pursuant to the terms of such Series of VRDP Shares to transfer to the transferee the right to receive from the Trust any dividends declared and unpaid for each day prior to the transferee becoming the Beneficial Owner of such VRDP Shares in exchange for payment of the Purchase Price for such VRDP Shares by the transferee.

(j) Dividends Credited Against Earliest Accumulated But Unpaid Dividends

. Any dividend payment made on shares of a Series of VRDP Shares that is insufficient to cover the entire amount of dividends payable shall first be credited against the earliest accumulated but unpaid dividends due with respect to such shares of such Series. Dividends in arrears for any past Dividend Period may be declared and paid at any time, without reference to any regular Dividend Payment Date, to the Holders as their names appear on the record books of the Trust on such date, not exceeding fifteen (15) days preceding the payment date thereof, as may be fixed by the Board of Trustees.

(k) Dividends Designated as Exempt-Interest Dividends

. Dividends on shares of a Series of VRDP Shares shall be designated as exempt-interest dividends up to the amount of the Net Tax-Exempt Income of the Trust, to the extent permitted by, and for purposes of, Section 852 of the Code.

3. Gross-Up Payments

. Holders of shares of a Series of VRDP Shares shall be entitled to receive, when, as and if declared by the Board of Trustees, out of funds legally available therefor in accordance with the Charter and applicable law, dividends in an amount equal to the aggregate Gross-up Payments as follows:

(a) If the Trust allocates any net capital gains or ordinary income taxable for regular federal income tax purposes to a dividend paid on shares of a Series of VRDP Shares without either having given advance notice thereof to the Remarketing Agent or simultaneously increasing such dividend payment by an additional amount, both as provided in Section 6 of Part II of this Certificate of Designation (such allocation being referred to herein as a "Taxable Allocation"), the Trust shall, prior to the end of the calendar year in which such dividend was paid, provide notice thereof to the Remarketing Agent and direct the Tender and Paying Agent to send such notice with a Gross-up Payment to the Holder that was entitled to such dividend payment during such calendar year at such Holder's address as the same appears or last appeared on the record books of the Trust.

(b) The Trust shall not be required to make Gross-up Payments with respect to any net capital gains or ordinary income determined by the Internal Revenue Service to be allocable in a manner different from the manner used by the Trust.

4. Designation of Special Rate Periods

(a) Length of and Preconditions for Special Rate Period

. The Trust, at its option, with the prior written consent of the Liquidity Provider, may designate any succeeding Subsequent Rate Period of a Series of VRDP Shares as a Special Rate Period (a "Special Rate Period") consisting of a specified number of Rate Period Days evenly divisible by seven (7) and not more than 1,820, subject to adjustment as provided in paragraph (b) of this Section 4. A designation of a Special Rate Period shall be effective only with the prior written consent of the Liquidity Provider and if (A) it is permitted by applicable law and the Charter, (B) notice thereof shall have been given in accordance with paragraph (c) and paragraph (d)(i) of this Section 4, (C) no shares of such Series of VRDP Shares are owned by the Liquidity Provider pursuant to the Purchase Obligation on either the Rate Determination Date for such proposed Special Rate Period or on the first (1st) day of such Special Rate Period and full cumulative dividends and any amounts due with respect to redemptions payable prior to such date have been paid in full, and (D) if any Notice of Redemption shall have been provided by the Trust pursuant to paragraph (c) of Section 10 of Part I of this Certificate of Designation with respect to any shares of such Series of VRDP Shares, the Redemption Price with respect to such VRDP Shares shall have been deposited with the Tender and Paying Agent. In the event the Trust wishes to designate any succeeding Subsequent Rate Period for shares of a Series of VRDP Shares as a Special Rate Period consisting of more than twenty-eight (28) Rate Period Days, the Trust shall notify Moody's (if Moody's is then rating shares of such Series of VRDP Shares at the request of the Trust), Fitch (if Fitch is then rating shares of such Series of VRDP Shares at the request of the Trust) and each Other Rating Agency (if any Other Rating Agency is then rating shares of such Series of VRDP Shares at the request of the Trust) in advance of the commencement of such Subsequent Rate Period that the Trust wishes to designate such Subsequent Rate Period as a Special Rate Period and shall provide Moody's (if Moody's is then rating shares of such Series of VRDP Shares at the request of the Trust), Fitch (if Fitch is then rating shares of such Series of VRDP Shares at the request of the Trust) and each Other Rating Agency (if any Other Rating Agency is then rating shares of such Series of VRDP Shares at the request of the Trust) with such documents as they may request.

(b) Adjustment of Length of Special Rate Period

. In the event the Trust wishes to designate a Subsequent Rate Period as a Special Rate Period, but the day that would otherwise be the last day of such Special Rate Period is not a Wednesday that is a Business Day in the case of a Series of VRDP Shares designated as "Series W-7 Variable Rate Demand Preferred Shares", then the Special Rate Period shall end on the next Business Day and the succeeding Subsequent Rate Period will end on the following Wednesday or, if the succeeding Subsequent Rate Period is a Special Rate Period, it shall end on a Wednesday as designated by the Trust, subject in each case to the foregoing Business Day requirement.

. If the Trust proposes to designate any succeeding Subsequent Rate Period for shares of a Series of VRDP Shares as a Special Rate Period pursuant to paragraph (a) of this Section 4, not less than twenty (20) (or such lesser number of days as may be agreed to from time to time by the Remarketing Agent) nor more than thirty (30) days prior to the date the Trust proposes to designate as the first (1st) day of such Special Rate Period (which shall be such day that would otherwise be the first (1st) day of a Minimum Rate Period), notice ("Notice of Proposed Special Rate Period") shall be sent by the Trust by first-class mail, postage prepaid or by Electronic Means, to the Holders of shares of such Series with copies provided to the Tender and Paying Agent, the Liquidity Provider and the Remarketing Agent. Each such notice shall state (A) that the Trust may exercise its option to designate a succeeding Subsequent Rate Period of shares of such Series as a Special Rate Period, specifying the first (1st) day thereof, (B) that the Trust will, by 11:00 a.m., New York City time, on the second Business Day immediately preceding such date (or by such later time or date, or both, as may be agreed to by the Remarketing Agent) notify the Remarketing Agent of either (x) its determination, subject to certain conditions, to exercise such option, or (y) its determination not to exercise such option, (C) the Rate Determination Date immediately prior to the first (1st) day of such Special Rate Period, (D) that such Special Rate Period shall not commence if (1) any shares of such Series of VRDP shares are owned by the Liquidity Provider pursuant to the Purchase Obligation on either the Rate Determination Date for such proposed Special Rate Period or on the first (1st) day of such Special Rate Period, or (2) full cumulative dividends or any amounts due with respect to redemptions payable prior to such Rate Determination Date have not been paid in full, (E) the scheduled Dividend Payment Dates for shares of such Series during such Special Rate Period, (F) the Special Redemption Provisions, if any, applicable to shares of such Series in respect of such Special Rate Period and (G) the Special Optional Tender Provisions, if any, applicable to shares of such Series in respect of such Special Rate Period.

(d) Notice of Special Rate Period

. No later than 11:00 a.m., New York City time, on the second Business Day immediately preceding the first (1st) day of any proposed Special Rate Period of shares of a Series of VRDP Shares as to which notice has been given as set forth in paragraph (c) of this Section 4 (or such later time or date, or both, as may be agreed to by the Remarketing Agent), the Trust shall deliver to the Remarketing Agent and the Liquidity Provider either:

(i)

a notice ("Notice of Special Rate Period") stating (A) that the Trust has determined to designate the next succeeding Rate Period of such Series of VRDP Shares as a Special Rate Period, specifying the same and the first (1st) day thereof, (B) the Rate Determination Date immediately prior to the first (1st) day of such Special Rate Period, (C) that such Special Rate Period shall not commence if (1) any shares of such Series of VRDP Shares are owned by the Liquidity Provider pursuant to the Purchase Obligation on either such Rate Determination Date or on the first (1st) day of such Special Rate Period, or (2) full cumulative dividends or any amounts due with respect to redemptions payable prior to such Rate Determination Date have not been paid in full, (D) the scheduled Dividend Payment Dates for shares of such Series of VRDP Shares during such Special Rate Period, (E) the Special Redemption Provisions, if any, applicable to shares of such Series of VRDP Shares in respect of such Special Rate Period and (F) the Special Optional Tender Provisions, if any, applicable to shares of such Series of VRDP Shares in respect of such Special Rate Period, such notice to be accompanied by a Basic Maintenance Report showing that, as of the third (3rd) Business Day immediately preceding such proposed Special Rate Period, Moody's Eligible Assets (if Moody's is then rating such VRDP Shares at the request of the Trust), Fitch Eligible Assets (if Fitch is then rating such VRDP Shares at the request of the Trust) and Other Rating Agency Eligible Assets (if any Other Rating Agency is then rating such VRDP Shares at the request of the Trust) each have an aggregate Discounted Value at least equal to the Basic Maintenance Amount as of such Business Day (assuming for purposes of the foregoing calculation that (a) the Maximum Rate is the Maximum Rate on such Business Day as if such Business Day were the Rate Determination Date for the proposed Special Rate Period, and (b) the Moody's Discount Factors applicable to Moody's Eligible Assets are determined by reference to the first Exposure Period (as defined in the Moody's Guidelines) longer than the Exposure Period then applicable to the Trust, as described in the Moody's Guidelines); or

(ii)	a notice stating that the Trust has determined not to exercise its option to designate a Special Rate Period of shares of such Series and that the next succeeding Rate Period of shares of such Series shall be a Minimum Rate Period.

(e) Failure to Deliver Notice of Special Rate Period

. If the Trust fails to deliver either of the notices described in paragraphs (d)(i) or (d)(ii) of this Section 4 (and, in the case of the notice described in paragraph (d)(i) of this Section 4, a Basic Maintenance Report to the effect set forth in such paragraph (but only if Moody's, Fitch or any Other Rating Agency is then rating the Series in question pursuant to the request of the Trust)) with respect to any designation of any proposed Special Rate Period to the Remarketing Agent and the Liquidity Provider by 11:00 a.m., New York City time, on the second Business Day immediately preceding the first (1st) day of such proposed Special Rate Period (or by such later time or date, or both, as may be agreed to by the Remarketing Agent and the Liquidity Provider), the Trust shall be deemed to have delivered a notice to the Remarketing Agent and the Liquidity Provider with respect to such Special Rate Period to the effect set forth in paragraph (d)(ii) of this Section 4. In the event the Trust delivers to the Remarketing Agent and the Liquidity Provider a notice described in paragraph (d)(i) of this Section 4, it shall file a copy of such notice with the Secretary of the Trust, and the contents of such notice shall be binding on the Trust. In the event the Trust delivers to the Remarketing Agent and the Liquidity Provider a notice described in paragraph (d)(ii) of this Section 4, the Trust will provide Moody's (if Moody's is then rating the VRDP Shares in question pursuant to the request of the Trust) and Fitch (if Fitch is then rating the VRDP Shares in question pursuant to the request of the Trust) and each Other Rating Agency (if any Other Rating Agency is then rating the VRDP Shares in question pursuant to the request of the Trust) a copy of such notice.

(f) Notwithstanding the foregoing, no Special Rate Period shall end later than the fifteenth (15th) day prior to the Scheduled Termination Date at which point the Rate Periods shall revert to Minimum Rate Periods.

5. Voting Rights

(a) One Vote Per VRDP Share

. Except as otherwise provided in the Charter or as otherwise required by law, (i) each Holder of shares of a Series of VRDP Shares shall be entitled to one vote for each such share held by such Holder on each matter submitted to a vote of shareholders of the Trust, and (ii) the holders of outstanding Preferred Shares, including each share of a Series of VRDP Shares, and of Common Shares shall vote together as a single class; provided, however, that the holders of outstanding Preferred Shares, including VRDP Shares, voting together as a class, to the exclusion of the holders of all other securities and classes of shares of the Trust, shall be entitled to elect two trustees of the Trust at all times, each Preferred Share, including each share of a Series of VRDP Shares, entitling the holder thereof to one vote. Subject to paragraph (b) of this Section 5, the holders of outstanding Common Shares and Preferred Shares, including VRDP Shares, voting together as a single class, shall elect the balance of the trustees.

(b) Voting for Additional Trustees

(i)

Voting Period. During any period in which any one or more of the conditions described in subparagraphs (A) or (B) of this paragraph (b)(i) shall exist (such period being referred to herein as a "Voting Period"), the number of trustees constituting the Board of Trustees shall be automatically increased by the smallest number that, when added to the two trustees elected exclusively by the holders of Preferred Shares, including the VRDP Shares, would constitute a majority of the Board of Trustees as so increased by such smallest number; and the holders of Preferred Shares, including the VRDP Shares, shall be entitled, voting together as a single class on a one-vote-per-share basis (to the exclusion of the holders of all other securities and classes of shares of the Trust), to elect such smallest number of additional trustees, together with the two trustees that such holders are in any event entitled to elect. A Voting Period shall commence:

(A) if at the close of business on any Dividend Payment Date accumulated dividends (whether or not earned or declared) on any outstanding Preferred Shares, including the VRDP Shares, equal to at least two (2) full years' dividends shall be due and unpaid and sufficient cash or specified securities shall not have been deposited with the Tender and Paying Agent for the payment of such accumulated dividends; or

(B) if at any time holders of Preferred Shares are entitled under the 1940 Act to elect a majority of the trustees of the Trust.

Upon the termination of a Voting Period, the voting rights described in this paragraph (b)(i) shall cease, subject always, however, to the revesting of such voting rights in the holders of Preferred Shares upon the further occurrence of any of the events described in this paragraph (b)(i).

(ii)

Notice of Special Meeting. As soon as reasonably practicable after the accrual of any right of the holders of Preferred Shares to elect additional trustees as described in paragraph (b)(i) of this Section 5, the Trust may call a special meeting of such holders, such call to be made by notice as provided in the bylaws of the Trust, such meeting to be held not less than ten (10) nor more than sixty (60) days after the date of mailing of such notice. If a special meeting is not called by the Trust, it may be called by any such holder on like notice. The record date for determining the holders entitled to notice of and to vote at such special meeting shall be not more than sixty (60) nor less than ten (10) days prior to the date of such special meeting. At any such special meeting and at each meeting of holders of Preferred Shares held during a Voting Period at which trustees are to be elected, such holders, voting together as a class (to the exclusion of the holders of all other securities and classes of shares of the Trust), shall be entitled to elect the number of trustees prescribed in paragraph (b)(i) of this Section 5 on a one-vote-per-share basis.

(iii)

Terms of Office of Existing Trustees. The terms of office of all persons who are trustees of the Trust at the time of a special meeting of Holders and holders of other Preferred Shares to elect trustees shall continue, notwithstanding the election at such meeting by the Holders and such other holders of other Preferred Shares of the number of trustees that they are entitled to elect, and the persons so elected by the Holders and such other holders of other Preferred Shares, together with the two incumbent trustees elected by the Holders and such other holders of other Preferred Shares and the remaining incumbent trustees elected by the holders of the Common Shares and Preferred Shares, shall constitute the duly elected trustees of the Trust.

(iv)

Terms of Office of Certain Trustees to Terminate Upon Termination of Voting Period. Simultaneously with the termination of a Voting Period, the terms of office of the additional trustees elected by the Holders and holders of other Preferred Shares pursuant to paragraph (b)(i) of this Section 5 shall terminate, the remaining trustees shall constitute the trustees of the Trust and the voting rights of the Holders and such other holders to elect additional trustees pursuant to paragraph (b)(i) of this Section 5 shall cease, subject to the provisions of the last sentence of paragraph (b)(i) of this Section 5.

(i)

Increases in Capitalization and Certain Amendments. So long as shares of any Series of VRDP Shares are Outstanding, the Trust shall not, without the affirmative vote or consent of the Holders of at least a majority of the VRDP Shares Outstanding at the time, in person or by proxy, either in writing or at a meeting, voting as a separate class: (a) authorize, create or issue any class or series of shares ranking prior to or on a parity with the VRDP Shares with respect to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Trust, or authorize, create or issue additional shares of any Series of VRDP Shares (except that, notwithstanding the foregoing, but subject to certain Rating Agency approvals, the Board of Trustees, without the vote or consent of the Holders, may with the prior written consent of the Liquidity Provider from time to time authorize and create, and the Trust may from time to time issue additional shares of, any Series of VRDP Shares or classes or series of Preferred Shares ranking on a parity with the VRDP Shares with respect to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Trust), or (b) amend, alter or repeal the provisions of the Charter, or this Certificate of Designation, whether by merger, consolidation or otherwise, so as to adversely affect any preference, right or power of such VRDP Shares or the Holders thereof set forth in the Charter or this Certificate of Designation; provided, however, that (i) none of the actions permitted by the exception to clause (a) above will be deemed to affect such preferences, rights or powers, (ii) a division of a VRDP Share will be deemed to affect such preferences, rights or powers only if the terms of such division adversely affect the Holders of the VRDP Shares and (iii) the authorization, creation and issuance of classes or series of shares ranking junior to VRDP Shares with respect to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Trust will be deemed to affect such preferences, rights or powers only if such issuance would, at the time thereof, cause the Trust not to satisfy the Minimum VRDP Shares Asset Coverage or, if Moody's, Fitch or any Other Rating Agency is then rating shares of a Series of VRDP Shares at the request of the Trust, the VRDP Shares Basic Maintenance Amount. For purposes of the foregoing, except as otherwise set forth in this Certificate of Designation, no matter shall be deemed to adversely affect any right, preference or power of a Series of VRDP Shares or the Holders thereof unless such matter (i) alters or abolishes the terms of any preferential rights of such Series, (ii) creates, alters or abolishes the terms of any right in respect of redemption of such Series, or (iii) creates or alters (other than to abolish or to comply with applicable law) the terms of any restriction on transfer applicable to such Series. So long as any shares of any Series of VRDP Shares are Outstanding, the Trust will not, without the affirmative vote or consent of the Holders of at least 66⅔% of the VRDP Shares Outstanding at the time, in person or by proxy, either in writing or at a meeting, voting as a separate class, file a voluntary application for relief under federal bankruptcy law or any similar application under state law for so long as the Trust is solvent and does not foresee becoming insolvent. If any action set forth above would adversely affect the rights of one or more Series (the "Affected Series") of VRDP Shares in a manner different from any other Series of VRDP Shares, the Trust will not approve any such action without the affirmative vote or consent of the Holders of at least a majority of the shares of each such Affected Series Outstanding at the time, in person or by proxy, either in writing or at a meeting (each such Affected Series voting as a separate class).

(ii)

1940 Act Matters. Unless a higher percentage is provided for in the Charter, (A) the affirmative vote of the holders of at least a "majority of the outstanding Preferred Shares," including VRDP Shares Outstanding at the time, voting as a separate class, shall be required to approve any conversion of the Trust from a closed-end to an open-end investment company and (B) the affirmative vote of the holders of a "majority of the outstanding Preferred Shares," including VRDP Shares Outstanding at the time, voting as a separate class, shall be required to approve any plan of reorganization (as such term is used in the 1940 Act) adversely affecting such shares. The affirmative vote of the holders of a "majority of the outstanding Preferred Shares," including VRDP Shares Outstanding at the time, voting as a separate class, shall be required to approve any action not described in the first sentence of this Section 5(c)(ii) requiring a vote of security holders of the Trust under Section 13(a) of the 1940 Act. For purposes of the foregoing, "majority of the outstanding Preferred Shares" means (i) 67% or more of such shares present at a meeting, if the Holders of more than 50% of such shares are present or represented by proxy, or (ii) more than 50% of such shares, whichever is less. In the event a vote of Holders of VRDP Shares is required pursuant to the provisions of Section 13(a) of the 1940 Act, the Trust shall, not later than ten (10) Business Days prior to the date on which such vote is to be taken, notify Moody's (if Moody's is then rating the VRDP Shares at the request of the Trust), Fitch (if Fitch is then rating the VRDP Shares at the request of the Trust) and each Other Rating Agency (if any Other Rating Agency is then rating the VRDP Shares at the request of the Trust) that such vote is to be taken and the nature of the action with respect to which such vote is to be taken.

(iii)

Exclusive Right to Vote on Certain Charter Amendments. Notwithstanding the foregoing, and except as otherwise required by the 1940 Act, (i) Holders of Outstanding shares of a Series of VRDP Shares will be entitled as a Series, to the exclusion of the holders of all other securities, including other Preferred Shares, Common Shares and other classes of capital shares of the Trust, to vote on matters affecting shares of such Series of VRDP Shares that do not adversely affect any of the rights of holders of such other securities, including other Preferred Shares, Common Shares and other classes of capital shares, as expressly set forth in the Charter, and (ii) Holders of Outstanding shares of a Series of VRDP Shares will not be entitled to vote on matters affecting any other Preferred Shares that do not adversely affect any of the rights of Holders of such Series of VRDP Shares, as expressly set forth in the Charter.

(d) Board of Trustees May Take Certain Actions Without Stockholder Approval

. The Trust is not required to maintain any particular preferred share ratings for a Series of VRDP Shares and the Board of Trustees may, subject to this Section 5(d), at any time, terminate the services of a Rating Agency then providing a rating for such Series with or without replacement, in either case, without the approval of Holders of shares of such Series of VRDP Shares or other shareholders of the Trust. The Trust is required to comply with the Rating Agency Provisions of a Rating Agency only if such Rating Agency is then rating a Series of VRDP Shares at the request of the Trust.

(i)

Notwithstanding anything herein to the contrary (including without limitation clause (ii) below), the Board of Trustees, without the approval of Holders of shares of any Series of VRDP Shares or other shareholders of the Trust, may terminate the services of any Rating Agency then providing a rating for a Series of VRDP Shares and replace it with another Rating Agency, provided that the Trust provides seven (7) days' notice by Electronic Means to Holders prior to terminating the services of a Rating Agency and replacing it with another Rating Agency. In the event a Rating Agency ceases to furnish a preferred share rating or the Trust terminates a Rating Agency with replacement in accordance with this clause (i), the Trust shall no longer be required to comply with the Rating Agency Provisions of the Rating Agency so terminated and, as applicable, the Trust shall be required to thereafter comply with the Rating Agency Provisions of each Rating Agency then providing a rating for a Series of VRDP Shares at the request of the Trust.

(ii)

(A) Notwithstanding anything herein to the contrary (including without limitation clause (i) above), the Board of Trustees, without the approval of Holders of shares of any Series of VRDP Shares or other shareholders of the Trust, may terminate the services of any Rating Agency then providing a rating for a Series of VRDP Shares without replacement, provided that (I) the Trust has given the Remarketing Agent, the Tender and Paying Agent, and the Liquidity Provider, and Moody's, Fitch and each Other Rating Agency, as applicable, and Holders of shares of such Series of VRDP Shares at least forty-five (45) calendar days' advance written notice of such termination of services, (II) the Trust is in compliance with the Moody's Provisions, the Fitch Provisions and the Other Rating Agency Provisions, as the case may be, at the time the notice required in clause (I) hereof is given and at the time of the termination of services, and (III) shares of such Series of VRDP Shares continue to be rated by at least one NRSRO at and after the time of the termination of services.

(B) On the date that the notice is given as described in the preceding clause (A) and on the date that the services of Moody's, Fitch or any Other Rating Agency, as applicable, are terminated, the Trust shall provide the Tender and Paying Agent and Moody's, Fitch and each Other Rating Agency, as applicable, with an officers' certificate as to the compliance with the provisions of the preceding clause (A), and, on such later date and thereafter, the Trust shall no longer be required to comply with the Rating Agency Provisions of the Rating Agency whose services were terminated.

(iii)

Notwithstanding anything herein to the contrary, but subject to this Section 5(d), the Rating Agency Guidelines, as they may be amended from time to time by the respective Rating Agency, will be reflected in a written document and may be amended by the respective Rating Agency without the vote, consent or approval of the Trust, the Board of Trustees or any holder of Preferred Shares, including any Series of VRDP Shares, or any other shareholder of the Trust. The Board of Trustees, without the vote or consent of any holder of Preferred Shares, including any Series of VRDP Shares, or any other shareholder of the Trust, may from time to time take such actions as may be reasonably required in connection with obtaining, maintaining or changing the rating of any Rating Agency that is then rating shares of a Series of VRDP Shares at the request of the Trust, and any such action will not be deemed to affect the preferences, rights or powers of Preferred Shares, including VRDP Shares, or the Holders thereof, provided that the Board of Trustees receives written confirmation from such Rating Agency, as applicable, then rating such shares of a Series of VRDP Shares at the request of the Trust (with such confirmation in no event being required to be obtained from a particular Rating Agency with respect to definitions or other provisions relevant only to and adopted in connection with another Rating Agency's rating of any Series of VRDP Shares) that any such action would not adversely affect the rating then assigned by such Rating Agency.

(iv)

Notwithstanding the foregoing, nothing in this Section 5 is intended in any way to limit the ability of (A) the Trust to make certain adjustments in the VRDP Shares Remarketing Agreement as provided under the definition of "Maximum Rate," subject to the limitations set forth in such definition, or (B) the Board of Trustees to, subject to applicable law, amend or alter any provisions of this Certificate of Designation, without the vote or consent of any holder of Preferred Shares, including any Series of VRDP Shares, or any other shareholder of the Trust, as otherwise provided in this Certificate of Designation.

(e) Voting Rights Set Forth Herein are Sole Voting Rights

. Unless otherwise required by law, the Holders of VRDP Shares shall not have any relative rights or preferences or other special rights other than those specifically set forth herein.

(f) No Preemptive Rights or Cumulative Voting

. The Holders of VRDP Shares shall have no preemptive rights or rights to cumulative voting.

(g) Voting for Trustees Sole Remedy for Trust's Failure to Pay Dividends

. In the event that the Trust fails to pay any dividends on shares of a Series of VRDP Shares, the exclusive remedy of the Holders of such Series shall be the right to vote for trustees pursuant to the provisions of this Section 5.

(h) Holders Entitled to Vote

. For purposes of determining any rights of the Holders to vote on any matter, whether such right is created by this Certificate of Designation, by the other provisions of the Charter, by statute or otherwise by applicable law, no Holder shall be entitled to vote any VRDP Shares and no VRDP Shares shall be deemed to be "Outstanding" for the purpose of voting or determining the number of shares required to constitute a quorum if, prior to or concurrently with the time of determination of the VRDP Shares entitled to vote or the VRDP Shares deemed Outstanding for quorum purposes, as the case may be, the requisite Notice of Redemption with respect to such VRDP Shares shall have been provided as set forth in paragraph (c) of Section 10 of Part I of this Certificate of Designation and Deposit Securities in an amount equal to the Redemption Price for the redemption of such VRDP Shares shall have been deposited in trust with the Tender and Paying Agent and segregated on the books and records of the Custodian for that purpose. VRDP Shares held (legally or beneficially) by the Trust or any affiliate of the Trust or otherwise controlled by the Trust shall not have any voting rights or be deemed to be Outstanding for voting or for calculating the voting percentage required on any other matter or other purposes.

6. Minimum VRDP Shares Asset Coverage

. The Trust shall maintain, as of the last Business Day of each month in which any VRDP Share is Outstanding, the Minimum VRDP Shares Asset Coverage.

7. VRDP Shares Basic Maintenance Amount

(a) So long as any VRDP Share is Outstanding, the Trust shall maintain, on each Valuation Date, and shall verify to its satisfaction that it is maintaining on such Valuation Date, (i) Moody's Eligible Assets having an aggregate Discounted Value equal to or greater than the VRDP Shares Basic Maintenance Amount (if Moody's is then rating the VRDP Shares at the request of the Trust), (ii) Fitch Eligible Assets having an aggregate Discounted Value equal to or greater than the VRDP Shares Basic Maintenance Amount (if Fitch is then rating the VRDP Shares at the request of the Trust), and (iii) Other Rating Agency Eligible Assets having an aggregate Discounted Value equal to or greater than the VRDP Shares Basic Maintenance Amount (if any Other Rating Agency is then rating the VRDP Shares at the request of the Trust).

(b) The Trust shall deliver to each Rating Agency which is then rating a Series of VRDP Shares at the request of the Trust and any other party specified in the Rating Agency Guidelines all certificates that are set forth in the respective Rating Agency Guidelines regarding Minimum VRDP Shares Asset Coverage, VRDP Shares Basic Maintenance Amount and/or related calculations at such times and containing such information as set forth in the respective Rating Agency Guidelines (each, a "Rating Agency Certificate"). A failure by the Trust to deliver a Rating Agency Certificate with respect to the VRDP Shares Basic Maintenance Amount shall be deemed to be delivery of a Rating Agency Certificate indicating the Discounted Value for all assets of the Trust is less than the VRDP Shares Basic Maintenance Amount, as of the relevant Valuation Date; provided, however, that the Trust shall have the ability to cure such failure to deliver a Rating Agency Certificate within one day of receipt of notice from such Rating Agency that, without limiting paragraph (a) above or modifying the VRDP Shares Basic Maintenance Cure Date, the Trust failed to deliver such Rating Agency Certificate.

8. Restrictions on Dividends and Other Distributions

(a) Dividends on Preferred Shares Other Than VRDP Shares

. Except as set forth in the next sentence, no dividends shall be declared or paid or set apart for payment on the shares of any class or Series of shares of the Trust ranking, as to the payment of dividends, on a parity with the VRDP Shares for any period unless full cumulative dividends have been or contemporaneously are declared and paid on the shares of each Series of VRDP Shares through its most recent Dividend Payment Date. When dividends are not paid in full upon the shares of each Series of VRDP Shares through its most recent Dividend Payment Date or upon the shares of any other class or series of shares of the Trust ranking on a parity as to the payment of dividends with the VRDP Shares through their most recent respective dividend payment dates, all dividends declared upon the VRDP Shares and any other such class or series of shares ranking on a parity as to the payment of dividends with the VRDP Shares shall be declared pro rata so that the amount of dividends declared per share on the VRDP Shares and such other class or series of shares shall in all cases bear to each other the same ratio that accumulated dividends per share on the VRDP Shares and such other class or series of shares bear to each other (for purposes of this sentence, the amount of dividends declared per VRDP Share shall be based on the Applicable Rate for such VRDP Share effective during the Dividend Periods during which dividends were not paid in full).

(b) Dividends and Other Distributions With Respect to Common Shares Under the 1940 Act

. The Board of Trustees shall not declare any dividend (except a dividend payable in Common Shares), or declare any other distribution, upon the Common Shares, or purchase Common Shares, unless in every such case the Preferred Shares have, at the time of any such declaration or purchase, an asset coverage (as defined in and determined pursuant to the 1940 Act) of at least 200% (or such other asset coverage as may in the future be specified in or under the 1940 Act as the minimum asset coverage for senior securities which are shares or stock of a closed-end investment company as a condition of declaring dividends on its common shares or stock) after deducting the amount of such dividend, distribution or purchase price, as the case may be.

. For so long as any VRDP Share is Outstanding, and except as set forth in paragraph (a) of this Section 8 and paragraph (c) of Section 11 of this Part I, (A) the Trust shall not declare, pay or set apart for payment any dividend or other distribution (other than a dividend or distribution paid in shares of, or in options, warrants or rights to subscribe for or purchase, Common Shares or other shares, if any, ranking junior to the VRDP Shares as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up) in respect of the Common Shares or any other shares of the Trust ranking junior to or on a parity with the VRDP Shares as to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up, or call for redemption, redeem, purchase or otherwise acquire for consideration any Common Shares or any other such junior shares (except by conversion into or exchange for shares of the Trust ranking junior to the VRDP Shares as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up), or any such parity shares (except by conversion into or exchange for shares of the Trust ranking junior to or on a parity with VRDP Shares as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up), unless (i) full cumulative dividends on shares of each Series of VRDP Shares through its most recently ended Dividend Period shall have been paid or shall have been declared and sufficient funds for the payment thereof deposited with the Tender and Paying Agent and (ii) the Trust has redeemed the full number of VRDP Shares required to be redeemed by any provision for mandatory redemption pertaining thereto, and (B) the Trust shall not declare, pay or set apart for payment any dividend or other distribution (other than a dividend or distribution paid in shares of, or in options, warrants or rights to subscribe for or purchase, Common Shares or other shares, if any, ranking junior to VRDP Shares as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up) in respect of Common Shares or any other shares of the Trust ranking junior to VRDP Shares as to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up, or call for redemption, redeem, purchase or otherwise acquire for consideration any Common Shares or any other such junior shares (except by conversion into or exchange for shares of the Trust ranking junior to VRDP Shares as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up), unless immediately after such transaction the Discounted Value of Moody's Eligible Assets (if Moody's is then rating the VRDP Shares at the request of the Trust), Fitch Eligible Assets (if Fitch is then rating the VRDP Shares at the request of the Trust) and Other Rating Agency Eligible Assets (if any Other Rating Agency is then rating the VRDP Shares at the request of the Trust) would each at least equal the Basic Maintenance Amount for such Series.

9. Rating Agency Restrictions

. For so long as any shares of any Series of VRDP Shares is Outstanding and any Rating Agency is then rating a Series of VRDP Shares at the request of the Trust, the Trust will not engage in certain proscribed transactions set forth in the Rating Agency Guidelines, unless it has received written confirmation from each such Rating Agency that proscribes the applicable transaction in its Rating Agency Guidelines that any such action would not impair the rating then assigned by such Rating Agency to a Series of VRDP Shares.

10. Redemption

(a) Optional Redemption

(i)

Subject to the provisions of subparagraph (iv) of this paragraph (a), shares of any Series of VRDP Shares may be redeemed, at the option of the Trust, at any time, as a whole or from time to time in part, out of funds legally available therefor and otherwise in accordance with applicable state law, at a redemption price per share equal to the sum of $100,000 plus an amount equal to accumulated but unpaid dividends thereon (whether or not earned or declared) to, but not including, the date fixed for redemption; provided, however, that (1) shares of a Series of VRDP Shares may not be redeemed in part if after such partial redemption fewer than fifty (50) shares of such Series would remain Outstanding; (2) shares of a Series of VRDP Shares are not redeemable by the Trust during the Initial Rate Period; and (3) subject to subparagraph (ii) of this paragraph (a), the Notice of Special Rate Period relating to a Special Rate Period of shares of a Series of VRDP Shares, as delivered to the Remarketing Agent and filed with the Secretary of the Trust, may provide that shares of such Series shall not be redeemable during the whole or any part of such Special Rate Period or shall be redeemable during the whole or any part of such Special Rate Period only upon payment of such redemption premium or premiums as shall be specified therein ("Special Redemption Provisions").

(ii)

A Notice of Special Rate Period relating to shares of a Series of VRDP Shares for a Special Rate Period thereof may contain Special Redemption Provisions only if the Trust's Board of Trustees, after consultation with the Remarketing Agent and the Liquidity Provider, determines that such Special Redemption Provisions are in the best interest of the Trust.

(iii)

If fewer than all of the Outstanding shares of a Series of VRDP Shares are to be redeemed pursuant to subparagraph (i) of this paragraph (a), the number of shares of such Series to be redeemed shall be selected either pro rata from the Holders of shares of such Series in proportion to the number of shares of such Series held by such Holders or by lot or in such manner as the Trust's Board of Trustees may determine to be fair and equitable. The Trust's Board of Trustees will have the full power and authority to prescribe the terms and conditions upon which shares of a Series of VRDP Shares will be redeemed from time to time.

(iv)

The Trust may not on any date send a Notice of Redemption pursuant to paragraph (c) of this Section 10 in respect of a redemption contemplated to be effected pursuant to this paragraph (a) unless on such date (a) the Trust has available Deposit Securities with maturity or tender dates not later than the day preceding the applicable redemption date and having a Market Value not less than the amount (including any applicable premium) due to Holders by reason of the redemption of shares of a Series of VRDP Shares on such redemption date and (b) the Discounted Value of Moody's Eligible Assets (if Moody's is then rating the shares of a Series of VRDP Shares at the request of the Trust), the Discounted Value of Fitch Eligible Assets (if Fitch is then rating the shares of a Series of VRDP Shares at the request of the Trust) and the Discounted Value of Other Rating Agency Eligible Assets (if any Other Rating Agency is then rating the shares of a Series of VRDP Shares at the request of the Trust) each at least equals the VRDP Shares Basic Maintenance Amount, and would at least equal the VRDP Shares Basic Maintenance Amount immediately subsequent to such redemption if such redemption were to occur on such date. For purposes of determining in clause (b) of the preceding sentence whether the Discounted Value of Moody's Eligible Assets at least equals the VRDP Shares Basic Maintenance Amount, the Moody's Discount Factors applicable to Moody's Eligible Assets shall be determined by reference to the first Exposure Period (as defined in the Moody's Guidelines) longer than the Exposure Period then applicable to the Trust, as described in the definition of Moody's Discount Factor herein.

(b) Mandatory Redemption

. (i) The Trust shall redeem, out of funds legally available therefor and otherwise in accordance with state law, all Outstanding Series W-7 VRDP Shares on June 1, 2041, at a redemption price equal to $100,000 per share plus accumulated but unpaid dividends thereon (whether or not earned or declared) to, but excluding, such date; provided, however, that if such date is not a Business Day, the redemption shall occur on the next succeeding Business Day, at a redemption price equal to $100,000 per share plus accumulated but unpaid dividends thereon (whether or not earned or declared) to, but excluding, June 1, 2041. The Trust also shall redeem, out of funds legally available therefor and otherwise in accordance with state law, at a redemption price equal to $100,000 per share plus accumulated but unpaid dividends thereon (whether or not earned or declared) to (but excluding) the date fixed by the Board of Trustees for redemption, certain of the shares of a Series of VRDP Shares, if the Trust fails to have either Moody's Eligible Assets (if Moody's is then rating the shares of a Series of VRDP Shares at the request of the Trust) with a Discounted Value, Fitch Eligible Assets (if Fitch is then rating the shares of a Series of VRDP Shares at the request of the Trust) with a Discounted Value, or Other Rating Agency Eligible Assets (if any Other Rating Agency is then rating the shares of a Series of VRDP Shares at the request of the Trust) with a Discounted Value greater than or equal to the VRDP Shares Basic Maintenance Amount, or fails to maintain the Minimum VRDP Shares Asset Coverage in accordance with this Certificate of Designation, and such failure is not cured on or before the VRDP Shares Basic Maintenance Cure Date or the Minimum VRDP Shares Asset Coverage Cure Date, as the case may be. In the event of failure by the Trust to have Rating Agency Eligible Assets with a Discounted Value greater than or equal to the VRDP Shares Basic Maintenance Amount, if then applicable, the Trust may seek to cure such failure on or prior to the VRDP Shares Basic Maintenance Cure Date by complying with the requirements of the Rating Agency or Rating Agencies, if any, then rating shares of such Series of VRDP Shares at the request of the Trust as in effect at the time of failure. The number of VRDP Shares to be redeemed shall be equal to the lesser of (A) the minimum number of VRDP Shares, together with all other Preferred Shares subject to redemption or retirement, the redemption of which, if deemed to have occurred immediately prior to the opening of business on the applicable Cure Date, would result in the Trust's having each of Moody's Eligible Assets (if Moody's is then rating shares of a Series of VRDP Shares at the request of the Trust) with a Discounted Value, Fitch Eligible Assets (if Fitch is then rating shares of a Series of VRDP Shares at the request of the Trust) with a Discounted Value and Other Rating Agency Eligible Assets (if any Other Rating Agency is then rating shares of a Series of VRDP Shares at the request of the Trust) with a Discounted Value greater than or equal to the VRDP Shares Basic Maintenance Amount or maintaining the Minimum VRDP Shares Asset Coverage, as the case may be, on the applicable Cure Date (provided, however, that if there is no such minimum number of VRDP Shares and other Preferred Shares the redemption or retirement of which would have such result, all VRDP Shares and Preferred Shares then outstanding shall be redeemed), and (B) the maximum number of VRDP Shares, together with all other Preferred Shares subject to redemption or retirement, that can be redeemed out of funds legally available therefor in accordance with the Charter and applicable law. In determining the VRDP Shares required to be redeemed in accordance with the foregoing, the Trust shall allocate the number required to be redeemed to satisfy the VRDP Shares Basic Maintenance Amount or the Minimum VRDP Shares Asset Coverage, as the case may be, pro rata among VRDP Shares and other Preferred Shares (and, then, pro rata among each Series of VRDP Shares) subject to redemption or retirement. The Trust shall effect such redemption on the date fixed by the Trust therefor, which date shall not be earlier than ten (10) days nor later than sixty (60) days after the applicable Cure Date, except that if the Trust does not have funds legally available for the redemption of all of the required number of VRDP Shares and other Preferred Shares which are subject to redemption or retirement or the Trust otherwise is unable as a result of applicable law to effect such redemption on or prior to sixty (60) days after the applicable Cure Date, the Trust shall redeem those VRDP Shares and other Preferred Shares which it was unable to redeem on the earliest practicable date on which it is able to effect such redemption. Except in the case of a Failed Remarketing Condition-Purchased VRDP Shares Redemption, as described below, if fewer than all of the Outstanding shares of a Series of VRDP Shares are to be redeemed pursuant to this paragraph (b), the number of shares of a Series of VRDP Shares to be redeemed shall be redeemed pro rata, by lot or other fair method as determined by the Trust's Board of Trustees from the Holders of VRDP Shares in proportion to the number of shares of such Series of VRDP Shares held by such Holders.

(ii)

(A) In accordance with this Certificate of Designation and if then required pursuant to the Fee Agreement, if the Liquidity Provider acquires any VRDP Shares pursuant to the Purchase Obligation and continues to be the beneficial owner for federal income tax purposes of such Purchased VRDP Shares for a continuous period of six (6) months during which such Purchased VRDP Shares are tendered for Remarketing on each Business Day in accordance with the Related Documents but cannot be successfully remarketed (i.e., a Failed Remarketing Condition—Purchased VRDP Shares shall have occurred and be continuing for such period of time with respect to such Purchased VRDP Shares), the Trust shall effect a Failed Remarketing Condition-Purchased VRDP Shares Redemption out of funds legally available for the redemption of the Purchased VRDP Shares that are subject to the Failed Remarketing Condition--Purchased VRDP Shares Redemption and in accordance with any other applicable law restrictions that apply to redemptions of shares; provided, that, as of the date of redemption: (i) to the extent any VRDP Shares are Outstanding and held by Persons other than the Liquidity Provider, the Purchase Obligation of the Liquidity Provider whose VRDP Shares are subject to the Failed Remarketing Condition-Purchased VRDP Shares Redemption remains in effect to the extent required by, and in accordance with, the VRDP Shares Purchase Agreement to which such Liquidity Provider is a party, and (ii) to the extent (a) any VRDP Shares are Outstanding and held by Persons other than the Liquidity Provider and (b) the Purchase Obligation of the Liquidity Provider whose VRDP Shares are subject to the Failed Remarketing Condition-Purchased VRDP Shares Redemption remains in effect to the extent required by, and in accordance with, the VRDP Shares Purchase Agreement to which such Liquidity Provider is a party, the Liquidity Provider whose VRDP Shares are subject to the Failed Remarketing Condition—Purchased VRDP Shares Redemption shall have made written affirmation to the Trust not later than the Business Day immediately preceding the Redemption Date to the effect that the Liquidity Provider is in compliance with the Purchase Obligation in accordance with its terms. Notwithstanding the foregoing proviso, any failure or delay by the Liquidity Provider whose VRDP Shares are subject to the Failed Remarketing Condition-Purchased VRDP Shares Redemption to deliver the affirmation referred to in the foregoing proviso shall not relieve the Trust of its obligation to effectuate a Failed Remarketing Condition-Purchased VRDP Shares Redemption and shall only result in a delay by the Trust to effectuate a Failed Remarketing Condition-Purchased VRDP Shares Redemption until one (1) Business Day following the date that such Liquidity Provider delivers such affirmation or such affirmation is no longer required. The six-month holding period for Purchased VRDP Shares acquired and continuously held as a result of a continuing Failed Remarketing Condition-Purchased VRDP Shares shall be determined by the Trust on a first-in, first-out basis. The Trust shall effect a Failed Remarketing Condition-Purchased VRDP Shares Redemption on the Redemption Date fixed by the Trust therefor, which date shall not be later than three (3) Business Days after the expiration of the six-month period, except that if the Trust does not have legally available funds for the redemption of all of the required number of Purchased VRDP Shares which are subject to the Failed Remarketing Condition-Purchased VRDP Shares Redemption or the Trust otherwise is unable as a result of applicable law restrictions that apply to redemptions of shares to effect such redemption on or prior to three (3) Business Days after the expiration of the six-month period, the Trust shall redeem those Purchased VRDP Shares which it was unable to redeem on the earliest practicable date on which it is able to effect such redemption out of legally available funds and in accordance with applicable law restrictions that apply to redemptions of shares.

(B) Upon the occurrence and continuance of a Failed Remarketing Condition-Purchased VRDP Shares with respect to any VRDP Shares, by the fifth (5th) Business Day following delivery of notice thereof from the Liquidity Provider in accordance with Section 7.08(c) of the Fee Agreement, the Trust shall cause the Custodian to segregate, by means of appropriate identification on its books and records or otherwise in accordance with the Custodian's normal procedures, from the other assets of the Trust (a "Liquidity Account") Liquidity Account Investments with a Market Value equal to at least 110% of the Liquidation Preference of such Purchased VRDP Shares. If, while the Failed Remarketing Condition-Purchased VRDP Shares with respect to such Purchased VRDP Shares is continuing, the aggregate Market Value of the Liquidity Account Investments included in the Liquidity Account for such Purchased VRDP Shares as of the close of business on any Business Day is less than 110% of the Liquidation Preference of such Purchased VRDP Shares, then the Trust shall cause the Custodian and the Investment Adviser to take all such necessary action, including segregating additional assets of the Trust as Liquidity Account Investments, so that the aggregate Market Value of the Liquidity Account Investments included in the Liquidity Account for such Purchased VRDP Shares is at least equal to 110% of the Liquidation Preference of such Purchased VRDP Shares not later than the close of business on the next succeeding Business Day. With respect to assets of the Trust segregated as Liquidity Account Investments, the Investment Adviser, on behalf of the Trust, shall be entitled to instruct the Custodian with a copy to the Liquidity Provider on any date to release any Liquidity Account Investments with respect to any Purchased VRDP Shares from such segregation and to substitute therefor other Liquidity Account Investments, so long as (x) the assets of the Trust segregated as Liquidity Account Investments with respect to such Purchased VRDP Shares at the close of business on such date have a Market Value equal to 110% of the Liquidation Preference of such Purchased VRDP Shares and (y) the assets of the Trust designated and segregated as Deposit Securities at the close of business on such date have a Market Value equal to the Liquidity Requirement (if any) determined in accordance with paragraph (C) below with respect to such Purchased VRDP Shares for such date. The Trust shall cause the Custodian not to permit any lien, security interest or encumbrance to be created or permitted to exist on or in respect of any Liquidity Account Investments included in the Liquidity Account for any Purchased VRDP Shares, other than liens, security interests or encumbrances arising by operation of law and any lien of the Custodian with respect to the payment of its fees or repayment for its advances. Notwithstanding anything expressed or implied herein to the contrary, the assets of the Liquidity Account shall continue to be assets of the Trust subject to the interests of all creditors and shareholders of the Trust.

(C) Subject to notice having been received as referred to in paragraph (B) above, the Market Value of the Deposit Securities held in the Liquidity Account for any Purchased VRDP Shares, from and after the day (or if such day is not a Business Day, the next succeeding Business Day) preceding the expiration of the six-month period for the Failed Remarketing Condition-Purchased VRDP Shares applicable to such Purchased VRDP Shares (which, for the avoidance of doubt, may result in multiple six month periods, each in respect of a Failed Remarketing Condition-Purchased VRDP Shares in respect of applicable Purchased VRDP Shares) specified in the table set forth below, shall not be less than the percentage of the Liquidation Preference for such Purchased VRDP Shares set forth below opposite such day (the "Liquidity Requirement"), but in all cases subject to the cure provisions of paragraph (D) below:

Number of Days* Preceding the Six Month Anniversary of Liquidity Provider's Purchase	Value of Deposit Securities as Percentage of Liquidation Preference
135	20%
105	40%
75	60%
45	80%
15	100%

Or if such day is not a Business Day, the next succeeding Business Day

(D) If the aggregate Market Value of the Deposit Securities included in the Liquidity Account for any Purchased VRDP Shares as of the close of business on any Business Day is less than the Liquidity Requirement in respect of such Purchased VRDP Shares for such Business Day, then the Trust shall cause the segregation of additional or substitute Deposit Securities in respect of the Liquidity Account for such Purchased VRDP Shares, so that the aggregate Market Value of the Deposit Securities included in the Liquidity Account for such Purchased VRDP Shares is at least equal to the Liquidity Requirement for such Purchased VRDP Shares not later than the close of business on the next succeeding Business Day.

(E) The Deposit Securities included in the Liquidity Account for any Purchased VRDP Shares may be applied by the Trust, in its discretion, towards payment of the Redemption Price for such Purchased VRDP Shares. Upon the earlier to occur of (x) the successful remarketing of the Purchased VRDP Shares or (y) the deposit by the Trust with the Tender and Paying Agent with arrangements satisfactory to the Liquidity Provider of Deposit Securities having an initial combined Market Value sufficient to effect the redemption of such Purchased VRDP Shares on the Redemption Date for such Purchased VRDP Shares, the requirement of the Trust to maintain a Liquidity Account for such Purchased VRDP Shares as contemplated by this Section 10(b)(ii) shall lapse and be of no further force and effect.

(F) The provisions of paragraphs (A) through (E) of this Section 10(b)(ii) may be amended by the Board of Trustees, by resolution duly adopted, without shareholder approval in order to conform to the terms of a Fee Agreement or as otherwise necessary or desirable in the judgment of the Board of Trustees, provided that the Board of Trustees receives the prior written consent of the Liquidity Provider and written confirmation from each Rating Agency, as applicable, then rating shares of a Series of VRDP Shares at the request of the Trust that any such amendments would not adversely affect the rating then assigned by such Rating Agency to such Series of VRDP Shares.

(iii)

At least six (6) months prior to the scheduled mandatory Redemption Date of June 1, 2041 specified in Section 10(b)(i) above, if any Series W-7 VRDP Shares then remain Outstanding, the Trust shall cause the Custodian to segregate in a Liquidity Account (but without duplication of any Liquidity Account then in effect pursuant to Section 10(b)(ii) above), by means of appropriate identification on its books and records or otherwise in accordance with the Custodian's normal procedures, from the other assets of the Trust, Liquidity Account Investments with a Market Value equal to at least 110% of the Liquidation Preference of the then Outstanding Series W-7 VRDP Shares. The Trust shall maintain such Liquidity Account in accordance with Section 10(b)(ii)(B), (C) and (D) above and comply with the requirements set forth therein with respect to Liquidity Account Investments and the Liquidity Requirement; provided, that for purposes of this Section 10(b)(iii) all references therein to Purchased VRDP Shares shall be deemed to be to all Outstanding Series W-7 VRDP Shares, all references therein to the Failed Remarketing Condition-Purchased VRDP Shares or the related six-month period shall be deemed to be to the six-month period preceding the scheduled mandatory Redemption Date of June 1, 2041, and the references to notice by the Liquidity Provider shall not be applicable. The Deposit Securities included in the Liquidity Account for the Outstanding Series W-7 VRDP Shares may be applied by the Trust, in its discretion, towards payment of the Redemption Price for the Outstanding Series W-7 VRDP Shares. Upon the deposit by the Trust with the Tender and Paying Agent with arrangements satisfactory to the Liquidity Provider of Deposit Securities having an initial combined Market Value sufficient to effect the redemption of the Outstanding Series W-7 VRDP Shares on June 1, 2041 Redemption Date for the Outstanding Series W-7 VRDP Shares, the requirement of the Trust to maintain a Liquidity Account for the Outstanding Series W-7 VRDP Shares as contemplated by this Section 10(b)(iii) shall lapse and be of no further force and effect.

. If the Trust shall determine or be required to redeem, in whole or in part, shares of a Series of VRDP Shares pursuant to paragraph (a) or (b)(i) of this Section 10, the Trust will send a notice of redemption (the "Notice of Redemption"), by Electronic Means (or by first-class mail, postage prepaid, in the case where the shares of such Series of VRDP Shares are in physical form), to Holders thereof and the Liquidity Provider or, in the case of a redemption pursuant to paragraph (b)(ii) of this Section 10, only to the Liquidity Provider, or request the Tender and Paying Agent, on behalf of the Trust to promptly do so by Electronic Means (or by first-class mail, postage prepaid, in the case where the shares of such Series of VRDP Shares are in physical form) so long as the Notice of Redemption is furnished by the Trust to the Tender and Paying Agent in electronic format at least five (5) Business Days prior to the date a Notice of Redemption is required to be delivered to the Holders, unless a shorter period of time shall be acceptable to the Tender and Paying Agent. A Notice of Redemption shall be sent to Holders not less than ten (10) days prior to the date fixed for redemption in such Notice of Redemption (the "Redemption Date"). Each such Notice of Redemption shall state: (i) the Redemption Date; (ii) the number of shares of such Series of VRDP Shares to be redeemed and the Series thereof; (iii) the CUSIP number for the VRDP Shares of such Series; (iv) the Redemption Price; (v) the place or places where the certificate(s), if any, for such shares (properly endorsed or assigned for transfer, if the Board of Trustees requires and the Notice of Redemption states) are to be surrendered for payment of the Redemption Price; (vi) that dividends on the shares of such Series of VRDP Shares to be redeemed will cease to accumulate from and after such Redemption Date; and (vii) the provisions of this Certificate of Designation under which such redemption is made. If fewer than all shares of a Series of VRDP Shares held by any Holder are to be redeemed, the Notice of Redemption delivered to such Holder shall also specify the number of shares of such Series of VRDP Shares to be redeemed from such Holder. The Trust may provide in any Notice of Redemption relating to a redemption contemplated to be effected pursuant to this Certificate of Designation that such redemption is subject to one or more conditions precedent and that the Trust shall not be required to effect such redemption unless each such condition has been satisfied at the time or times and in the manner specified in such Notice of Redemption. No defect in the Notice of Redemption or delivery thereof shall affect the validity of redemption proceedings, except as required by applicable law.

(d) No Redemption Under Certain Circumstances

. Notwithstanding the provisions of paragraphs (a) or (b) of this Section 10, if any dividends on shares of a Series of VRDP Shares (whether or not earned or declared) are in arrears, no shares of such Series shall be redeemed unless all Outstanding shares of such Series are simultaneously redeemed, and the Trust shall not otherwise purchase or acquire any shares of such Series; provided, however, that the foregoing shall not prevent the purchase or acquisition of Outstanding shares of a Series of VRDP Shares pursuant to the successful completion of an otherwise lawful purchase or exchange offer made on the same terms to Holders of all Outstanding shares of such Series of VRDP Shares.

(e) Absence of Funds Available for Redemption

. To the extent that any redemption for which a Notice of Redemption has been provided is not made by reason of the absence of legally available funds therefor in accordance with the Charter and applicable law, such redemption shall be made as soon as practicable to the extent such funds become available. A failure to redeem shares of a Series of VRDP Shares shall be deemed to exist at any time after the date specified for redemption in a Notice of Redemption when the Trust shall have failed, for any reason whatsoever, to deposit in trust with the Tender and Paying Agent the Redemption Price with respect to any shares for which such Notice of Redemption has been sent; provided, however, that the foregoing shall not apply in the case of the Trust's failure to deposit in trust with the Tender and Paying Agent the Redemption Price with respect to any shares where (1) the Notice of Redemption relating to such redemption provided that such redemption was subject to one or more conditions precedent and (2) any such condition precedent shall not have been satisfied at the time or times and in the manner specified in such Notice of Redemption. Notwithstanding the fact that the Trust may not have redeemed shares of a Series of VRDP Shares for which a Notice of Redemption has been provided, dividends may be declared and paid on shares of a Series of VRDP Shares and shall include those shares of such Series of VRDP Shares for which a Notice of Redemption has been provided.

(f) Tender and Paying Agent as Trustee of Redemption Payments by Trust

. All moneys paid to the Tender and Paying Agent for payment of the Redemption Price of shares of a Series of VRDP Shares called for redemption shall be held in trust by the Tender and Paying Agent for the benefit of Holders of shares so to be redeemed.

(g) Shares for Which Notice of Redemption Has Been Given Are No Longer Outstanding

. Provided a Notice of Redemption has been provided pursuant to paragraph (c) of this Section 10, the Trust shall irrevocably (except to the extent set forth below in this paragraph (g)) deposit with the Tender and Paying Agent, no later than 12:00 noon, New York City time, on a Business Day not less than ten (10) Business Days preceding the redemption date specified in such notice, Deposit Securities in an aggregate amount equal to the Redemption Price to be paid on the Redemption Date in respect of any shares of a Series of VRDP Shares that are subject to such notice. Provided a Notice of Redemption has been provided pursuant to paragraph (c) of this Section 10, upon the deposit with the Tender and Paying Agent of Deposit Securities in an amount sufficient to redeem the shares of a Series of VRDP Shares that are the subject of such notice, dividends on such shares of a Series of VRDP Shares shall cease to accumulate and such shares of a Series of VRDP Shares shall no longer be deemed to be Outstanding, except as noted below with respect to the VRDP Shares Purchase Agreement, for any purpose, and all rights of the Holders of the shares of a Series of VRDP Shares so called for redemption shall cease and terminate, except the right of such Holders to receive the Redemption Price, but without any interest or other additional amount, except as provided in paragraph (e)(i) of Section 2 of this Part I and in Section 3 of Part I of this Certificate of Designation. Upon surrender in accordance with the Notice of Redemption of the certificates for any shares of a Series of VRDP Shares so redeemed (properly endorsed or assigned for transfer, if the Board of Trustees shall so require and the Notice of Redemption shall so state), the Redemption Price shall be paid by the Tender and Paying Agent to the Holders of shares of a Series of VRDP Shares subject to redemption. In the case that fewer than all of the shares represented by any such certificate are redeemed, a new certificate shall be issued, representing the unredeemed shares, without cost to the Holder thereof. The Trust shall be entitled to receive from the Tender and Paying Agent, promptly after the date fixed for redemption, any cash or other Deposit Securities deposited with the Tender and Paying Agent in excess of (i) the aggregate Redemption Price of the shares of a Series of VRDP Shares called for redemption on such date and (ii) all other amounts to which Holders of shares of a Series of VRDP Shares called for redemption may be entitled. Any funds so deposited that are unclaimed at the end of ninety (90) days from such redemption date shall, to the extent permitted by law, be repaid to the Trust, after which time the Holders of shares of a Series of VRDP Shares so called for redemption may look only to the Trust for payment of the Redemption Price and all other amounts to which they may be entitled. The Trust shall be entitled to receive, from time to time after the date fixed for redemption, any interest on the funds so deposited. Notwithstanding the foregoing, shares of a Series of VRDP Shares will be deemed to be Outstanding for purposes of the VRDP Shares Purchase Agreement until redeemed by the Trust.

(h) Compliance With Applicable Law

. In effecting any redemption pursuant to this Section 10, the Trust shall use its best efforts to comply with all applicable conditions precedent to effecting such redemption under the 1940 Act and any applicable Massachusetts or other state law, but shall effect no redemption except in accordance with the 1940 Act and any applicable Massachusetts or other state law.

(i) Only Whole Shares of a Series of VRDP Shares May Be Redeemed

. In the case of any redemption pursuant to this Section 10, only whole shares of a Series of VRDP Shares shall be redeemed, and in the event that any provision of the Charter would require redemption of a fractional share, the Remarketing Agent shall be authorized to round up so that only whole shares are redeemed.

(j) Modification of Redemption Procedures

. Notwithstanding the foregoing provisions of this Section 10, the Trust may, in its sole discretion, modify the procedures set forth above with respect to notification of redemption of VRDP Shares, provided that such modification does not materially and adversely affect the Holders of VRDP Shares or cause the Trust to violate any law, rule or regulation, or to in any way alter the obligations of the Tender and Paying Agent without its prior written consent. Furthermore, if in the sole discretion of the Board of Trustees, after consultation with counsel, modification of the foregoing redemption provisions (x) are permissible under the rules and regulations or interpretations of the SEC and under other applicable law and (y) would not cause a material risk as to the treatment of the VRDP Shares as equity for U.S. federal income tax purposes, the Board of Trustees, without shareholder approval, by resolution and with the prior written consent of the Liquidity Provider may modify such redemption procedures.

11. Liquidation Rights

(a) Ranking

. The shares of a Series of VRDP Shares shall rank on a parity with each other, with shares of any other Series of VRDP Shares and with shares of any other Series of Preferred Shares as to the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Trust.

(b) Distributions Upon Liquidation

. Upon the dissolution, liquidation or winding up of the affairs of the Trust, whether voluntary or involuntary, the Holders of VRDP Shares then Outstanding shall be entitled to receive and to be paid out of the assets of the Trust available for distribution to its shareholders and otherwise in accordance with applicable state law, before any payment or distribution shall be made on the Common Shares or on any other class of shares of the Trust ranking junior to the VRDP Shares upon dissolution, liquidation or winding up, an amount equal to the Liquidation Preference with respect to such shares plus an amount equal to all dividends thereon (whether or not earned or declared) accumulated but unpaid to (but not including) the date of final distribution in same day funds, together with any payments required to be made pursuant to Section 3 of Part I of this Certificate of Designation in connection with the liquidation of the Trust. After the payment to the Holders of VRDP Shares of the full preferential amounts provided for in this paragraph (b), the Holders of VRDP Shares as such shall have no right or claim to any of the remaining assets of the Trust.

. In the event the assets of the Trust available for distribution to the Holders of VRDP Shares upon any dissolution, liquidation or winding up of the affairs of the Trust, whether voluntary or involuntary, shall be insufficient to pay in full all amounts to which such Holders are entitled pursuant to paragraph (b) of this Section 11, no such distribution shall be made on account of any shares of any other class or Series of Preferred Shares ranking on a parity with the VRDP Shares with respect to the distribution of assets upon such dissolution, liquidation or winding up unless proportionate distributive amounts shall be paid on account of the VRDP Shares, ratably, in proportion to the full distributable amounts for which holders of all such parity shares are respectively entitled upon such dissolution, liquidation or winding up.

(d) Rights of Junior Shares

. Subject to the rights of the holders of shares of any series or class or classes of shares ranking on a parity with the VRDP Shares with respect to the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Trust, after payment shall have been made in full to the Holders of VRDP Shares as provided in paragraph (b) of this Section 11, but not prior thereto, any other series or class or classes of shares ranking junior to the VRDP Shares with respect to the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Trust shall, subject to the respective terms and provisions (if any) applying thereto, be entitled to receive any and all assets remaining to be paid or distributed, and the Holders of VRDP Shares shall not be entitled to share therein.

(e) Certain Events Not Constituting Liquidation

. Neither the sale of all or substantially all the property or business of the Trust, nor the merger, consolidation or reorganization of the Trust into or with any business or statutory trust, corporation or other entity nor the merger, consolidation or reorganization of any business or statutory trust, corporation or other entity into or with the Trust shall be a dissolution, liquidation or winding up, whether voluntary or involuntary, for the purposes of this Section 11.

12. Purchase Obligation

. As long as shares of any Series of VRDP Shares are Outstanding, the Trust shall maintain a VRDP Shares Purchase Agreement providing for a Purchase Obligation with a Liquidity Provider with (i) short-term debt ratings in one of the two highest ratings categories from the Requisite NRSROs or (ii) such other short-term debt ratings, if any, as may be required for the shares of such Series of VRDP Shares to satisfy the eligibility criteria under Rule 2a-7 under the 1940 Act on an ongoing basis to the extent that the Trust can do so on a commercially reasonable basis as determined in the sole discretion of the Board of Trustees. If the Trust maintains a VRDP Shares Purchase Agreement providing a Purchase Obligation, the provisions herein relating to the Liquidity Provider shall be operative and the following shall apply:

(a) The Trust shall notify, or cause the Tender and Paying Agent to notify, Holders by Electronic Means, or by first-class mail, postage prepaid, in the case in which shares of a Series of VRDP Shares are in physical form, (A) in the event of a Mandatory Tender Event or Mandatory Purchase Event, (B) upon at least seven (7) days' prior notice in the event that there is a substitute Liquidity Provider (including, but not limited to, as to the Liquidity Provider, its consolidation, amalgamation with, or merger with or into, another entity, or the transfer of all or substantially all of the Liquidity Provider's assets to another entity), or (C) any downgrade in the rating of the Series of VRDP Shares or the Liquidity Provider by an NRSRO then rating shares of such Series of VRDP Shares at the request of the Trust or Liquidity Provider.

(b) In the event of a Failed Remarketing Condition, the Trust will require in the Tender and Paying Agent Agreement that the Tender and Paying Agent will notify the Trust and Holders by telephone or Electronic Means, or by first-class-mail, postage prepaid, in the case in which shares of a Series of VRDP Shares are in physical form of such Failed Remarketing Condition.

(c) Each share of a Series of VRDP Shares shall be subject to tender to the Tender and Paying Agent for Remarketing on the related Purchase Date or, in the event (i) no Remarketing occurs or (ii) pursuant to an attempted Remarketing shares remain unsold and the Remarketing Agent does not purchase for its own account the unsold shares of a Series of VRDP Shares tendered to the Tender and Paying Agent for Remarketing (provided that the Remarketing Agent may seek to sell such shares of a Series of VRDP Shares in a subsequent Remarketing prior to the Purchase Date) to the Liquidity Provider for purchase on such Purchase Date pursuant to a Notice of Purchase. If there is no Tender and Paying Agent or the Tender and Paying Agent does not perform such obligation pursuant to the VRDP Shares Purchase Agreement, Beneficial Owners and their Agent Members shall have the right to tender their shares of a Series of VRDP Shares directly to the Liquidity Provider pursuant to a Final Notice of Purchase. In the event there is no Tender and Paying Agent or for any reason the Tender and Paying Agent does not perform its obligations under the VRDP Shares Purchase Agreement, the Trust (i) upon becoming aware thereof, shall promptly notify the Liquidity Provider, the Remarketing Agent and Holders by Electronic Means of such event, and (ii) so long as such event is continuing, shall use its best efforts to direct the Remarketing Agent to forward, concurrently with the delivery thereof to the Liquidity Provider or as promptly as practicable thereafter, any Remarketing Notice to each Beneficial Owner or Holder tendering shares of the Series of VRDP Shares that are the subject of such notice.

(d) The Trust will require in the Tender and Paying Agent Agreement that, pursuant to a Tender, shares of a Series of VRDP Shares that are not sold in a Remarketing will be tendered by the Tender and Paying Agent to the Liquidity Provider for payment of the Purchase Price on the Purchase Date pursuant to the VRDP Shares Purchase Agreement.

(e) Except as set forth in Section 10(b) of Part I of this Certificate of Designation in connection with a mandatory redemption of shares of a Series of VRDP Shares, the Trust shall have no obligation to purchase shares of a Series of VRDP Shares acquired by the Liquidity Provider pursuant to the VRDP Shares Purchase Agreement or otherwise.

(f) Shares of a Series of VRDP Shares are subject to Mandatory Purchase by the Liquidity Provider upon the occurrence of a Mandatory Purchase Event. So long as shares of such Series of VRDP Shares are in book-entry form and held through the Securities Depository, any Mandatory Purchase will be effected automatically through the book-entry system of the Securities Depository, without any action required on the part of the Holders or Beneficial Owners. Promptly following the occurrence of a Mandatory Purchase Event, and in any event within three (3) Business Days thereafter, the Trust, or the Tender and Paying Agent at the direction of the Trust (provided, that the Tender and Paying Agent may require up to two (2) Business Days prior notification by Electronic Means by the Trust), shall provide a Mandatory Purchase Notice by Electronic Means to Holders and the Liquidity Provider, specifying a Mandatory Purchase Date for all Outstanding shares of such Series of VRDP Shares. The Mandatory Purchase Date shall not be later than seven (7) days following the date a Mandatory Purchase Notice is sent to Holders by Electronic Means, and in any event shall be not later than the Business Day immediately preceding the termination of the VRDP Shares Purchase Agreement. Any notice given in respect of a Mandatory Purchase under this Certificate of Designation shall be conclusively presumed to have been duly given, whether or not the Holders receive such notice. Upon the occurrence of a Mandatory Purchase Event, all Outstanding shares of a Series of VRDP Shares automatically shall be subject to Mandatory Purchase by the Liquidity Provider at the Purchase Price on the Mandatory Purchase Date, including any shares of such Series of VRDP Shares tendered pursuant to an Optional Tender or Mandatory Tender for which the Purchase Date has not yet occurred.

(g) In the event shares of a Series of VRDP Shares are issued in certificated form and a Holder fails to deliver such shares of such Series of VRDP Shares to which a Mandatory Purchase relates, on or prior to the Mandatory Purchase Date, the Holder of shares of such Series of VRDP Shares will not be entitled to any payment (including any accumulated but unpaid dividends thereon, whether or not earned or declared) other than the Purchase Price of such undelivered VRDP Shares as of the scheduled Purchase Date. Any such undelivered shares of a Series of VRDP Shares will be deemed to be delivered to the Tender and Paying Agent, and the Tender and Paying Agent will place stop-transfer orders against the undelivered shares of such Series of VRDP Shares. Any moneys held by the Tender and Paying Agent for the purchase of undelivered shares of such Series of VRDP Shares shall be held in a separate account, shall not be invested, and shall be held for the exclusive benefit of the Holder of such undelivered shares of such Series of VRDP Shares. The undelivered shares of a Series of VRDP Shares shall be deemed to be no longer Outstanding (except as to entitlement to payment of the Purchase Price), and the Trust will issue to the purchaser replacement share certificates for such shares in lieu of such undelivered shares of such Series of VRDP Shares.

(h) The Trust shall use best efforts to engage at all times a Tender and Paying Agent to perform the duties specified in this Certificate of Designation, the Tender and Paying Agent Agreement and the VRDP Shares Purchase Agreement with respect to the Tender and Paying Agent.

The provisions of paragraphs (a) through (g) of this Section 12 may be amended by the Board of Trustees, by resolution duly adopted, without shareholder approval in order to conform to a VRDP Shares Purchase Agreement providing a Purchase Obligation.

13. Miscellaneous

(a) Amendment of or Supplements to this Certificate of Designation

. Subject to the provisions of Section 9 of Part I of this Certificate of Designation, the Board of Trustees may, by resolution duly adopted, without shareholder approval (except as otherwise provided by this Certificate of Designation or required by applicable law), amend or supplement this Certificate of Designation to (1) reflect any amendments or supplements hereto which the Board of Trustees is entitled to adopt pursuant to the terms of this Certificate of Designation without shareholder approval or (2) designate additional Series of VRDP Shares (and terms relating thereto). Each such additional Series shall be governed by the terms of this Certificate of Designation as so amended or supplemented.

(b) No Fractional Shares

. No fractional shares of a Series of VRDP Shares shall be issued.

. Shares of a Series of VRDP shares which are redeemed, exchanged or otherwise acquired by the Trust shall return to the status of authorized and unissued Preferred Shares without designation as to series, provided, however, that any shares of a Series of VRDP Shares which are provisionally delivered by the Trust to or for the account of an agent of the Trust or to or for the account of a purchaser of the shares of the Series of VRDP Shares, but for which final payment is not received by the Trust, shall return to the status of authorized and unissued shares of such Series of VRDP Shares.

(d) Purchase Obligation Part of the VRDP Shares

. Each Holder and Beneficial Owner, by virtue of acquiring shares of a Series of VRDP Shares, is deemed to have agreed to treat the Purchase Obligation as part of the VRDP Shares rather than as a separate property right.

(e)	Treatment of VRDP Shares as Equity

. Each Holder and Beneficial Owner, by virtue of acquiring shares of a Series of VRDP Shares, is deemed to have agreed to treat the VRDP Shares as equity in the Trust for U.S. federal income tax purposes.

(f) Board of Trustees May Resolve Ambiguities

. To the extent permitted by applicable law, the Board of Trustees may interpret or adjust the provisions of this Certificate of Designation to resolve any inconsistency or ambiguity or to remedy any formal defect, and may amend this Certificate of Designation with respect to VRDP Shares prior to the issuance of such VRDP Shares.

(g) Headings Not Determinative

. The headings contained in this Certificate of Designation are for convenience of reference only and shall not affect the meaning or interpretation of this Certificate of Designation.

(h) Notices

. All notices or communications, unless otherwise specified in the Bylaws of the Trust or this Certificate of Designation, shall be sufficiently given if in writing and delivered in person, by Electronic Means or mailed by first-class mail, postage prepaid.

(i)	Applicable Law

(j) . For purposes of the Section entitled "Designation" in this Certificate of Designation and all of the provisions in this Certificate of Designation relating to any “distribution” as defined in section 1.40 of the Massachusetts Business Corporation Act (M.G.L. ch. 156D) (the “Massachusetts Business Corporation Act”) on or in respect of the VRDP Shares, including, without limitation, Sections 2, 3, 10 and 11 of Part I of this Certificate of Designation, applicable law shall include section 6.40 of the Massachusetts Business Corporation Act, as if the Trust were a Massachusetts corporation subject to the Massachusetts Business Corporation Act.

(j)	Personal Liability

(k) . The Charter provides that the name "BlackRock MuniYield Investment Fund" refers to the trustees under the Charter collectively as trustees, but not as individuals or personally; and no trustee, shareholder, officer, employee or agent of the Trust shall be held to any personal liability, nor shall resort be had to their private property for the satisfaction of any obligation or claim or otherwise in connection with the affairs of the Trust, but the Trust property only shall be liable.

PART II

1. Remarketing Procedures.

(a) Pursuant to an Optional Tender, Beneficial Owners may elect to tender their VRDP Shares (in denominations of $100,000 and integral multiples thereof) for purchase at the Purchase Price on the Purchase Date designated in the Notice of Tender (or if such day is not a Business Day, on the next succeeding Business Day) by a proper delivery of a Notice of Tender to the Tender and Paying Agent. Each Notice of Tender shall be irrevocable (except as described below) and effective upon receipt and shall:

(i)	be delivered by a Beneficial Owner, directly or through its Agent Member, by email transmission (or if email transmission shall be unavailable, by facsimile transmission), to the Tender and Paying Agent not later than 2:00 p.m., New York City time, on any Business Day;

(ii)	state the series and the aggregate number of VRDP Shares to be purchased, the CUSIP number of the Series of VRDP Shares to be purchased, and the Purchase Date and be in substantially the form of and contain such other information specified in an exhibit to the VRDP Shares Purchase Agreement; and

(iii)

state that the tendering Beneficial Owner acknowledges that such Beneficial Owner is required to deliver the VRDP Shares that are the subject of a Notice of Tender (that has not been duly revoked as provided below) on or before 2:00 p.m., New York City time, on the Purchase Date.

(b) Upon receipt of a Notice of Tender, the Tender and Paying Agent shall provide a copy of such notice to the Liquidity Provider and the Remarketing Agent (with a copy to the Trust) as promptly as practicable by Electronic Means, but no later than 4:00 p.m., New York City time, on the date of receipt or deemed receipt.

(c) Any Notice of Tender delivered to the Tender and Paying Agent by a Beneficial Owner or its Agent Member after 2:00 p.m., New York City time, shall be deemed to have been received by the Tender and Paying Agent on the next succeeding Business Day, and the Purchase Date shall be adjusted such that the Purchase Date shall be the Business Day next succeeding the date specified as the Purchase Date in the Notice of Tender.

(d) The determination of the Tender and Paying Agent as to whether a Notice of Tender has been properly delivered pursuant to the foregoing paragraph (a) shall be conclusive and binding upon the Beneficial Owner and its Agent Member.

(e) (i) Shares of a Series of VRDP Shares are subject to Mandatory Tender upon the occurrence of a Mandatory Tender Event.

(ii) So long as the shares of a Series of VRDP Shares are in book-entry form and held through the Securities Depository, any Mandatory Tender will be effected automatically through the book-entry system of the Securities Depository, without any action required on the part of the Holders or Beneficial Owners. Promptly following the occurrence of a Mandatory Tender Event, and in any event within three (3) Business Days thereafter, the Trust, or the Tender and Paying Agent at the direction of the Trust (provided, that the Tender and Paying Agent may require up to two (2) Business Days prior notification by Electronic Means by the Trust), shall provide a Mandatory Tender Notice by Electronic Means to Holders, the Remarketing Agent and the Liquidity Provider, specifying a Purchase Date for all Outstanding shares of such Series of VRDP Shares. Any notice given in respect of a Mandatory Tender under this Certificate of Designation will be conclusively presumed to have been duly given, whether or not the Holders receive such notice.

(iii) Upon the occurrence of a Mandatory Tender Event, all Outstanding shares of a Series of VRDP Shares automatically shall be subject to Mandatory Tender and delivered to the Tender and Paying Agent for purchase on the designated Purchase Date by purchasers in the Remarketing in the event of a successful Remarketing or otherwise by the Liquidity Provider, including any shares of such Series of VRDP Shares previously tendered pursuant to an Optional Tender for which the Purchase Date has not yet occurred. In the event that shares of a Series of VRDP Shares are issued in certificated form and a Holder of shares of such Series of VRDP Shares fails to deliver such shares to which a Mandatory Tender relates on or prior to the Purchase Date, the Holder of shares of such Series of VRDP Shares shall not be entitled to any payment (including any accumulated but unpaid dividends thereon, whether or not earned or declared) other than the Purchase Price of such undelivered shares of such Series of VRDP Shares as of the scheduled Purchase Date. Any such undelivered shares of such Series of VRDP Shares will be deemed to be delivered to the Tender and Paying Agent, and the Tender and Paying Agent will place stop-transfer orders against the undelivered shares of such Series of VRDP Shares. Any moneys held by the Tender and Paying Agent for the purchase of undelivered shares of a Series of VRDP Shares will be held in a separate account by the Tender and Paying Agent, will not be invested, and will be held for the exclusive benefit of the Holder of such undelivered shares of such Series of VRDP Shares. The undelivered shares of a Series of VRDP Shares will be deemed to be no longer Outstanding (except as to entitlement to payment of the Purchase Price), and the Trust will issue to the purchaser replacement share certificates in lieu of such undelivered shares of such Series of VRDP Shares.

(f) A Beneficial Owner or its Agent Member that delivered a Notice of Tender in connection with an Optional Tender may deliver in writing by email transmission (or if email transmission shall be unavailable, by facsimile transmission) to the Tender and Paying Agent, not later than 10:00 a.m., New York City time, on or prior to the Business Day immediately preceding the Purchase Date, a notice to the effect that such Beneficial Owner wishes to revoke its election to tender some or all of the shares of a Series of VRDP Shares that were specified in such Notice of Tender to be purchased (a "Notice of Revocation"). Any Notice of Revocation delivered to the Tender and Paying Agent shall be promptly delivered by Electronic Means by the Tender and Paying Agent to the Liquidity Provider and the Remarketing Agent (with a copy to the Trust) by 12:00 noon, New York City time, on the Business Day immediately preceding the relevant Purchase Date. The Tender and Paying Agent shall contact the Remarketing Agent by Electronic Means by 1:45 p.m., New York City time, if such notification has not been received by such time. The Remarketing Agent (following receipt of such Notice of Revocation) shall notify the Tender and Paying Agent and the Liquidity Provider of the number of shares of such Series of VRDP Shares specified in such Notice of Revocation that are subject to an agreement of sale pursuant to a Remarketing by Electronic Means not later than 2:00 p.m., New York City time, on the Business Day immediately preceding the Purchase Date. The Tender and Paying Agent shall deliver such notification to the Beneficial Owner or its Agent Member promptly following receipt from the Remarketing Agent, and in any event by 4:00 p.m., New York City time, on the Business Day immediately preceding the Purchase Date. Any such Notice of Revocation shall be effective (without further action on the part of the Beneficial Owner or its Agent Member) as a revocation of the Optional Tender of the number of shares of such Series of VRDP Shares specified therein as being sought to be revoked, but (except as set forth below) only if and to the extent that the Remarketing Agent has not entered into an agreement to sell shares of such Series of VRDP Shares. A Notice of Revocation shall be effective as to the number of shares of a Series of VRDP Shares specified therein as having been revoked less the number of shares of such Series of VRDP Shares in respect of which the Remarketing Agent has so notified the Tender and Paying Agent and the Liquidity Provider that it has entered into an agreement of sale. Notwithstanding the foregoing, tendered shares of a Series of VRDP Shares, if any, that remain unsold on the related Purchase Date shall be allocated by the Remarketing Agent to each Notice of Revocation received in respect of shares of such Series of VRDP Shares tendered for purchase on such Purchase Date and not already satisfied in the chronological order in which each such Notice of Revocation was received by the Tender and Paying Agent, and each such Notice of Revocation shall be effective only to the extent of such allocation and availability of unsold shares of such Series of VRDP Shares.

(g) In connection with any Special Rate Period designated pursuant to Section 4 of Part I of this Certificate of Designation, the Board of Trustees, without the vote or consent of any Holder of any shares of any Series of VRDP Shares but with the prior written consent of the Liquidity Provider, in the Notice of Special Rate Period relating to a Series of the VRDP Shares, as delivered to the Remarketing Agent and the Liquidity Provider, may provide for optional tender provisions relating solely to such Special Rate Period ("Special Optional Tender Provisions") whereby the minimum number of days' notice required for an Optional Tender may exceed seven (7) days as specified in the Special Optional Tender Provisions for such Special Rate Period. The designation of the Special Rate Period will be a Mandatory Tender Event in accordance with the definition thereof.

(h) The Trust shall use its best efforts to engage at all times a Remarketing Agent that is a nationally recognized securities dealer with experience in remarketing variable-rate securities to use its best efforts to find purchasers for all shares of a Series of VRDP Shares properly tendered pursuant to a Tender.

2. Remarketing Schedule.

(a) In connection with any attempted Remarketing, all tendered shares of a Series of VRDP Shares shall be remarketed at the Purchase Price of such shares. The calculation of the Purchase Price of the shares of such Series of VRDP Shares that are remarketed or purchased by the Liquidity Provider shall be made by the Remarketing Agent in advance of such Remarketing or purchase and, together with the details of the aggregate number and Purchase Price of remarketed shares of such Series of VRDP Shares and the aggregate number and Purchase Price of shares of such Series of VRDP Shares to be purchased by the Liquidity Provider pursuant to the Purchase Obligation, shall be communicated by the Remarketing Agent to the Trust, the Liquidity Provider and the Tender and Paying Agent by Electronic Means by 2:00 p.m., New York City time, on the Business Day immediately preceding the Purchase Date, as described below. The proceeds of any sale of any remarketed shares of a Series of VRDP Shares by the Remarketing Agent relating to tendered shares of such Series of VRDP Shares shall be used by the Tender and Paying Agent for the purchase of the tendered shares of such Series of VRDP Shares at the Purchase Price, and the terms of the sale will provide for the wire transfer of such Purchase Price by the Remarketing Agent to be received by the Tender and Paying Agent no later than 11:00 a.m., New York City time, on the related Purchase Date for payment to the Agent Member of the Beneficial Owner, in the case of an Optional Tender, or Holder, in the case of a Mandatory Tender, tendering shares of such Series of VRDP Shares for sale through the Securities Depository in immediately available funds against delivery of the tendered shares of such Series of VRDP Shares to the Tender and Paying Agent through the Securities Depository, the delivery of such VRDP Shares to the Tender and Paying Agent through the Securities Depository no later than 2:00 p.m., New York City time, on the related Purchase Date and the re-delivery of such shares of such Series of VRDP Shares by means of "FREE" delivery through the Securities Depository to the Remarketing Agent for delivery to the purchaser's Agent Member through the Securities Depository by 3:00 p.m., New York City time, on the related Purchase Date.

(b) By 2:00 p.m., New York City time, on the Business Day immediately preceding each Purchase Date, the Remarketing Agent shall deliver a notice, in the form attached as Annex I to the Remarketing Agreement, to the Tender and Paying Agent and the Liquidity Provider (and, at the direction of the Trust, concurrently therewith or as promptly as practicable thereafter, to each Beneficial Owner or Holder tendering VRDP Shares that are the subject of such notice) (a "Remarketing Notice"), by e-mail transmission or facsimile transmission, that sets forth the number of shares of the Series of VRDP Shares, if any, that it successfully remarketed for purchase on such Purchase Date and the aggregate Purchase Price of such sold shares of the Series of VRDP Shares and the number of shares of such Series of VRDP Shares, if any, not successfully remarketed for purchase on such Purchase Date and the aggregate Purchase Price of such unsold shares of the Series of VRDP Shares to be paid by the Liquidity Provider. If the Remarketing Notice states that the Remarketing Agent has not successfully remarketed all of the shares of the Series of VRDP Shares to be purchased on such Purchase Date, the Tender and Paying Agent shall promptly, and in any event not later than 4:00 p.m., New York City time, on such Business Day, deliver by Electronic Means to the Liquidity Provider (with a copy to the Trust) a preliminary Notice of Purchase (a "Preliminary Notice of Purchase") that, subject to delivery of the Final Notice of Purchase on the Purchase Date described below, provides for the purchase by the Liquidity Provider of the number of such shares of the Series of VRDP Shares that the Remarketing Agent stated in the Remarketing Notice as not having been successfully remarketed, including the aggregate Purchase Price of such shares of the Series of VRDP Shares, as calculated by the Remarketing Agent. If the Remarketing Notice states that the Remarketing Agent has not successfully remarketed all of the shares of the Series of VRDP Shares to be purchased on such Purchase Date (or if proceeds from a Remarketing for any tendered shares of the Series of VRDP Shares have not been received for any reason by the Tender and Paying Agent by 11:00 a.m., New York City time, on the Purchase Date), the Tender and Paying Agent shall deliver by Electronic Means to the Liquidity Provider (with a copy to the Trust) by 12:00 noon, New York City time, on such Purchase Date a Final Notice of Purchase that states the number of shares of the Series of VRDP Shares required to be purchased by the Liquidity Provider. For purposes of the Final Notice of Purchase, any tendered shares of the Series of VRDP Shares for which remarketing proceeds have not been received for any reason by the Tender and Paying Agent by 11:00 a.m., New York City time, on the Purchase Date, shall be treated as not having been successfully remarketed and shall be required to be purchased by the Liquidity Provider. Except for manifest error, the payment obligation of the Liquidity Provider shall equal the Purchase Price of the shares of the Series of VRDP Shares stated in the Final Notice of Purchase delivered to the Liquidity Provider as being required to be purchased by the Liquidity Provider.

(c) The Liquidity Provider shall, no later than 2:00 p.m., New York City time, on a Purchase Date for any shares of a Series of VRDP Shares, wire transfer the aggregate Purchase Price of all shares of such Series of VRDP Shares in respect of which Final Notices of Purchase have been delivered to it for purchase of shares of such Series of VRDP Shares on such date, as follows: (i) in the case of a Final Notice of Purchase delivered by the Tender and Paying Agent, by wire transfer, in immediately available funds, to the account of the Tender and Paying Agent specified by the Tender and Paying Agent in any such Final Notice of Purchase; and (ii) in the event there is no Tender and Paying Agent or for any reason the Tender and Paying Agent does not perform its obligations under the VRDP Shares Purchase Agreement and the Liquidity Provider has received a Remarketing Notice that such shares of such Series of VRDP Shares have not been the subject of an agreement of sale in a Remarketing and has received written notice from the Trust that there is no Tender and Paying Agent or that the Tender and Paying Agent does not intend to perform its obligations under the VRDP Shares Purchase Agreement, in the case of a Final Notice of Purchase delivered by a Beneficial Owner or its Agent Member, in the case of an Optional Tender, or by a Holder, in the case of a Mandatory Tender, by payment against delivery of the shares of such Series of VRDP Shares that are the subject of any such Final Notice of Purchase, through means of the Securities Depository in the case of shares of such Series of VRDP Shares in the form of global securities.

(d) Upon receipt by the Tender and Paying Agent from the Beneficial Owner or its Agent Member, in the case of an Optional Tender, or by the Holder, in the case of a Mandatory Tender, of tendered shares of a Series of VRDP Shares and the payment by the Tender and Paying Agent to such Beneficial Owner or its Agent Member, or such Holder as the case may be, of the Purchase Price therefor on the applicable Purchase Date, the Tender and Paying Agent shall deliver to the Liquidity Provider, by means of "FREE" delivery through the system of the Securities Depository, shares of such Series of VRDP Shares in satisfaction of the Liquidity Provider's Purchase Obligation on such Purchase Date. Any funds paid by the Liquidity Provider and held in the account of the Tender and Paying Agent for the payment of the Purchase Price shall be held in trust (i) in the case of an Optional Tender, on the Purchase Date, for the benefit of the tendering Beneficial Owners or their Agent Members until the shares of the Series of VRDP Shares are delivered by the tendering Beneficial Owners or their Agent Members and, after the Purchase Date, for the benefit of the Liquidity Provider, for payment of the Purchase Price upon delivery of the shares of such Series of VRDP Shares or, with respect to shares of such Series of VRDP Shares that are not delivered, for return to the Liquidity Provider upon its request and (ii) in the case of a Mandatory Tender, for the benefit of the tendering Holders until delivery of the shares of such Series of VRDP Shares by the tendering Holders against payment therefor. Any funds paid by the Remarketing Agent and held in an account of the Tender and Paying Agent for the payment of the Purchase Price in connection with a Remarketing shall be held in trust (i) in the case of an Optional Tender, on the Purchase Date, for the benefit of the tendering Beneficial Owners or their Agent Members until the shares of the Series of VRDP Shares are delivered by the tendering Beneficial Owners or their Agent Members and, after the Purchase Date, for the benefit of the Remarketing Agent on account of purchasers purchasing in a Remarketing or for the Remarketing Agent's account to the extent it has advanced the Purchase Price of any shares of such Series of VRDP Shares on behalf of one or more purchasers, as applicable, for payment of the Purchase Price upon delivery of the shares of such Series of VRDP Shares or, with respect to shares of such Series of VRDP Shares that are not delivered, for return to the Remarketing Agent on account of purchasers purchasing in a Remarketing or for the Remarketing Agent's account to the extent it has advanced the Purchase Price of any shares of such Series of VRDP Shares on behalf of one or more purchasers, as applicable, upon the Remarketing Agent's request and (ii) in the case of a Mandatory Tender, for the benefit of the tendering Holders until delivery of the shares of the Series of VRDP Shares by the tendering Holders against payment therefor. Upon receipt of the shares of a Series of VRDP Shares from the tendering Beneficial Owners or their Agent Members, in the case of an Optional Tender, or from the tendering Holders, in the case of a Mandatory Tender, by the Tender and Paying Agent, the Tender and Paying Agent shall pay, subject to receipt of the Purchase Price by the Tender and Paying Agent in the form of remarketing proceeds from the Remarketing Agent, with respect to the shares of such Series of VRDP Shares remarketed by the Remarketing Agent, or in the form of payment pursuant to the VRDP Shares Purchase Agreement from the Liquidity Provider, with respect to the shares of such Series of VRDP Shares subject to purchase pursuant to the Purchase Obligation, the Purchase Price for shares of such Series of VRDP Shares to such tendering Beneficial Owner, Agent Member or Holder, as the case may be. In accordance with and subject to the foregoing, the Tender and Paying Agent shall effect any such payment on the applicable Purchase Date.

(e) Except as otherwise expressly provided for herein, the purchase and delivery of tendered shares of a Series of VRDP Shares in the form of global securities and their Remarketing will be accomplished in accordance with the applicable procedures of the Securities Depository.

(f) In connection with the allocation of shares of a Series of VRDP Shares tendered for Remarketing by the Liquidity Provider and any other Holder of shares of such Series of VRDP Shares in any Remarketing, the Remarketing Agent shall allocate those shares of such Series of VRDP Shares previously acquired by the Liquidity Provider pursuant to its Purchase Obligation first to any purchasers in a Remarketing (such allocation coming first from those shares of such Series of VRDP Shares acquired earliest by the Liquidity Provider).

(g) The Remarketing Agent and the Tender and Paying Agent each shall use commercially reasonable efforts to meet the timing requirements set forth above. Subject to the VRDP Shares Remarketing Agreement, the Remarketing Agent may, in its sole discretion, modify the settlement procedures set forth above with respect to any Remarketing upon ten (10) days' prior written notice to the Trust, the Liquidity Provider and the Tender and Paying Agent, provided any such modification does not adversely affect the Holders, the Beneficial Owners, the Tender and Paying Agent, the Liquidity Provider or the Trust. The Remarketing Agent may sell shares of a Series of VRDP Shares for its own account outside of a Remarketing at a price other than the Purchase Price.

(h) At any time after the termination of the VRDP Shares Purchase Agreement (or with respect to a remarketing of shares of a Series of VRDP Shares held by the Liquidity Provider as to which any then-effective Purchase Obligation by a successor liquidity provider is inapplicable), any shares of a Series of VRDP Shares unsold in a Remarketing will be returned to the relevant tendering Beneficial Owners or their Agent Members, or the relevant tendering Holders, as the case may be, by the Tender and Paying Agent.

3. Determination of Applicable Rate

(a) The Applicable Rate shall be determined by the Remarketing Agent on and as of each Rate Determination Date as the lowest rate under then-existing market conditions that in the Remarketing Agent's sole judgment would result in the shares of the Series of VRDP Shares on the first (1st) day of the Subsequent Rate Period next succeeding the Rate Determination Date having a market value equal to the Liquidation Preference thereof (plus accumulated but unpaid dividends thereon, whether or not earned or declared). Such determination shall be conclusive and binding upon the interested parties. The Applicable Rate shall not be more than the Maximum Rate.

(b) The Remarketing Agent shall establish the Applicable Rate by 5:00 p.m., New York City time, on each Rate Determination Date to the nearest one-thousandth (0.001) of one percent per annum for the Subsequent Rate Period. The Applicable Rate shall be in effect from and including the first (1st) day following such Rate Determination Date to and including the following Rate Determination Date. The Remarketing Agent shall make the Applicable Rate available after 5:00 p.m., New York City time on the Rate Determination Date by Electronic Means to the Trust, the Tender and Paying Agent and the Liquidity Provider and post the Applicable Rate on Bloomberg on such Rate Determination Date.

(c) In the event that the Remarketing Agent establishes the Maximum Rate as the Applicable Rate for a Subsequent Rate Period, the Remarketing Agent shall notify the Trust and the Tender and Paying Agent of the Maximum Rate by e-mail transmission or facsimile transmission after 5:00 P.M., New York City time, on each Rate Determination Date. The Trust will require in the Tender and Paying Agent Agreement that the Tender and Paying Agent will notify the Liquidity Provider and the Holders of VRDP Shares by first-class mail, postage prepaid (in the case of physical shares), or by Electronic Means (in the case of VRDP Shares in the form of global securities) that the Applicable Rate for the Subsequent Rate Period is the Maximum Rate.

(d) In the event the Remarketing Agent does not or is unable to determine the Applicable Rate, or if there is no Remarketing Agent, the Applicable Rate shall be the Maximum Rate.

(e) In the event of a Failed Remarketing Condition, the Applicable Rate as of the close of business on the day the Failed Remarketing Condition first occurs will be adjusted to the Maximum Rate (with the Applicable Spread subject to adjustment as set forth in the definition of Applicable Spread) and the Maximum Rate will continue to be the Applicable Rate (i) until the first (1st) day of the next succeeding Subsequent Rate Period after a Failed Remarketing Condition no longer exists in the case of a Minimum Rate Period or a Special Rate Period of twenty-eight (28) Rate Period Days or fewer, and (ii) until the first (1st) day of the next succeeding Dividend Period after the Failed Remarketing Condition no longer exists in the case of a Special Rate Period of greater than twenty-eight (28) Rate Period Days.

4. Failed Remarketing Condition

. In the event of a Failed Remarketing Condition, pursuant to the Tender and Paying Agent Agreement, the Tender and Paying Agent shall promptly provide notice of a Failed Remarketing Condition, but in any event within two (2) Business Days of receipt by the Tender and Paying Agent of notice from the Trust of the occurrence of such Failed Remarketing Condition, by Electronic Means (or by first-class mail, postage prepaid, in the case where VRDP Shares are in physical form) to the Holders (with a copy to the Trust).

5. Purchase of VRDP Shares by Remarketing Agent

. The Remarketing Agent in its sole discretion may purchase for its own account shares of a Series of VRDP Shares in a Remarketing; however, the Remarketing Agent shall not be obligated to purchase any shares of a Series of VRDP Shares that would otherwise remain unsold in a Remarketing. None of the Trust, the Tender and Paying Agent or any Remarketing Agent shall be obligated in any case to provide funds to make payment to a Beneficial Owner or its Agent Member upon such Beneficial Owner's tender of its shares of a Series of VRDP Shares in a Remarketing unless, in each case, such shares of such Series of VRDP Shares were acquired for the account of the Trust, the Tender and Paying Agent or the Remarketing Agent.

6. Notification of Allocations

. Whenever the Trust intends to include any net capital gains or ordinary income taxable for regular federal income tax purposes in any dividend on shares of a Series of VRDP Shares, the Trust may notify the Remarketing Agent and Tender and Paying Agent of the amount to be so included (i) not later than fourteen (14) calendar days preceding the first Rate Determination Date on which the Applicable Rate for such dividend is to be established, and (ii) for any successive Rate Determination Date on which the Applicable Rate for such dividend is to be established, not later than the close of business on the immediately preceding Rate Determination Date. Whenever such advance notice is received from the Trust, the Tender and Paying Agent will notify each Holder and the Remarketing Agent will promptly notify each potential Beneficial Owner or its Agent Member. With respect to a Rate Period for which such advance notice was given and whose dividends are comprised partly of such ordinary income or capital gains and partly of exempt interest income, the different types of income will be paid in the same relative proportions for each day during the Rate Period. The Trust may also include such ordinary income or capital gains in a dividend on shares of a Series of VRDP Shares without giving advance notice thereof if it increases the dividends by an additional amount calculated as if such income was a Taxable Allocation and the additional amount was a Gross-up Payment, provided the Trust will notify the Tender and Paying Agent of the additional amounts to be included in such dividend at least five (5) Business Days prior to the applicable Dividend Payment Date.

7. Transfers

(a) Unless otherwise permitted by the Trust, a Beneficial Owner or Holder may sell, transfer or otherwise dispose of shares of a Series of VRDP Shares only in whole shares and only pursuant to a Remarketing in accordance with the Remarketing Procedures set forth in Part II of this Certificate of Designation, provided, however, that (a) a sale, transfer or other disposition of shares of a Series of VRDP Shares from a Beneficial Owner who holds shares through an Agent Member to another Beneficial Owner who holds shares through the same Agent Member shall be permitted, and (b) in the case of all transfers other than pursuant to Remarketings, the Agent Member (or other Person, if permitted by the Trust) to whom such transfer is made shall advise the Remarketing Agent. The Trust has not registered the shares of any Series of VRDP Shares under the Securities Act. Accordingly, the shares of each Series of VRDP Shares are subject to restrictions on transferability and resale and may only be purchased by and sold to "qualified institutional buyers" (as defined in Rule 144A under the Securities Act or any successor provision) in accordance with Rule 144A under the Securities Act or any successor provision or any exemption from registration available and otherwise in accordance with the legend set forth on the face of the share certificate for the share of a Series of VRDP Shares.

(b) The Investment Adviser, affiliated persons of the Investment Adviser (as defined in Section 2(a)(3) of the 1940 Act) (other than the Trust, in the case of a purchase of shares of a Series of VRDP Shares which are to be cancelled within ten (10) days of purchase by the Trust), and Persons over which the Investment Adviser, or affiliated persons of the Investment Adviser (as defined in Section 2(a)(3) of the 1940 Act), exercise discretionary investment or voting authority (other than the Trust, in the case of a purchase of shares of a Series of VRDP Shares which are to be cancelled within ten (10) days of purchase by the Trust), are not permitted to purchase shares of a Series of VRDP Shares without the prior written consent of the Liquidity Provider, and any such purchases shall be void ab initio; provided, however, that the Trust shall give prompt notice to Beneficial Owners by Electronic Means upon any of the foregoing Persons, singly or in the aggregate, acquiring a beneficial interest in 20% or more of the shares of a Series of VRDP Shares; provided, further, that without regard to the preceding requirements, purchases of shares of a Series of VRDP Shares may be made by broker-dealers that are affiliated persons of the Investment Adviser in riskless principal transactions with respect to such purchases of shares of a Series of VRDP Shares.

(c) If at any time the Trust is not furnishing information to the SEC pursuant to Section 13 or 15(d) of the Exchange Act, in order to preserve the exemption for resales and transfers under Rule 144A, the Trust shall furnish, or cause to be furnished, to Holders of shares of a Series of VRDP Shares and prospective purchasers of shares of a Series of VRDP Shares, upon request, information with respect to the Trust satisfying the requirements of subsection (d)(4) of Rule 144A.

8. Global Certificate

Prior to the commencement of a Voting Period, (i) all of the shares of a Series of VRDP Shares Outstanding from time to time shall be represented by one or more global certificates registered in the name of the Securities Depository or its nominee and countersigned by the Tender and Paying Agent and (ii) no registration of transfer of shares of a Series of VRDP Shares shall be made on the books of the Trust to any Person other than the Securities Depository or its nominee. The foregoing restriction on registration of transfer shall be conspicuously noted on the face or back of the certificates of VRDP Shares in such a manner as to comply with the requirements of Section 8-204 of the Uniform Commercial Code as in effect in the Commonwealth of Massachusetts, or any successor provisions.
