For purposes of the maximum underlying obligor requirement described above, any Municipal Bond backed by the guaranty, letter of credit or insurance issued by a third party will be deemed to be issued by such third party if the issuance of such third party credit is the sole determinant of the rating on such Bond.

For so long as the AMPS are rated by Moody’s, the Corporation will not enter into any such reverse repurchase agreements unless it has received written confirmation from Moody’s that such transactions would not impair the rating then assigned the AMPS by Moody’s.

To the extent permitted under the Code, dividends on shares of AMPS will be designated as exempt-interest dividends. For the purposes of this section, the term “net tax-exempt income” shall exclude capital gains of the Corporation.

(b) (i) Cash dividends on shares of AMPS shall accumulate from the Date of Original Issue and shall be payable, when, as and if declared by the Board of Directors, out of funds legally available therefor, commencing on the Initial Dividend Payment Date with respect to the AMPS. Following the Initial Dividend Payment Date for the AMPS, dividends on the AMPS will be payable, at the option of the Corporation, either (i) with respect to any 7-Day Dividend Period and any Short Term Dividend Period of 35 or fewer days, on the day next succeeding the last day thereof, or (ii) with respect to any Short Term Dividend Period of more than 35 days and with respect to any Long Term Dividend Period, monthly on the first Business Day of each calendar month during such Short Term Dividend Period or Long Term Dividend Period and on the day next succeeding the last day thereof (each such date referred to in clause (i) or (ii) being herein referred to as a “Normal Dividend Payment Date”), except that if such Normal Dividend Payment Date is not a Business Day, then the Dividend Payment Date shall be the first Business Day next succeeding such Normal Dividend Payment Date. Although any particular Dividend Payment Date may not occur on the originally scheduled date because of the exception discussed above, the next succeeding Dividend Payment Date, subject to such exception, will occur on the next following originally scheduled date. If for any reason a Dividend Payment Date cannot be fixed as described above, then the Board of Directors shall fix the Dividend Payment Date. The

Board of Directors by resolution prior to authorization of a dividend by the Board of Directors may change a Dividend Payment Date if such change does not adversely affect the contract rights of the Holders of shares of AMPS set forth in the Charter. The Initial Dividend Period, 7-Day Dividend Periods and Special Dividend Periods are hereinafter sometimes referred to as Dividend Periods. Each dividend payment date determined as provided above is hereinafter referred to as a “Dividend Payment Date.”

(ii) Each dividend shall be paid to the Holders as they appear in the Stock Register as of 12:00 noon, Eastern time, on the Business Day preceding the Dividend Payment Date. 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 they appear on the Stock Register on a date, not exceeding 15 days prior to the payment date therefor, as may be fixed by the Board of Directors of the Corporation.

(c) (i) During the period from and including the Date of Original Issue to but excluding the Initial Dividend Payment Date (the “Initial Dividend Period”), the Applicable Rate shall be the Initial Dividend Rate. Commencing on the Initial Dividend Payment Date, the Applicable Rate for each subsequent dividend period (hereinafter referred to as a “Subsequent Dividend Period”), which Subsequent Dividend Period shall commence on and include a Dividend Payment Date and shall end on and include the calendar day prior to the next Dividend Payment Date (or last Dividend Payment Date in a Dividend Period if there is more than one Dividend Payment Date), shall be equal to the rate per annum that results from implementation of the Auction Procedures.

The Applicable Rate for each Dividend Period commencing during a Non-Payment Period shall be equal to the Non-Payment Period Rate; and each Dividend Period, commencing

after the first day of, and during, a Non-Payment Period shall be a 7-Day Dividend Period. Except in the case of the willful failure of the Corporation to pay a dividend on a Dividend Payment Date or to redeem any shares of AMPS on the date set for such redemption, any amount of any dividend due on any Dividend Payment Date (if, prior to the close of business on the second Business Day preceding such Dividend Payment Date, the Corporation has declared such dividend payable on such Dividend Payment Date to the Holders of such shares of AMPS as of 12:00 noon, Eastern time, on the Business Day preceding such Dividend Payment Date) or redemption price with respect to any shares of AMPS not paid to such Holders when due may be paid to such Holders in the same form of funds by 12:00 noon, Eastern time, on any of the first three Business Days after such Dividend Payment Date or due date, as the case may be, provided that, such amount is accompanied by a late charge calculated for such period of non-payment at the Non-Payment Period Rate applied to the amount of such non-payment based on the actual number of days comprising such period divided by 365. In the case of a willful failure of the Corporation to pay a dividend on a Dividend Payment Date or to redeem any shares of AMPS on the date set for such redemption, the preceding sentence shall not apply and the Applicable Rate for the Dividend Period commencing during the Non-Payment Period resulting from such failure shall be the Non-Payment Period Rate. For the purposes of the foregoing, payment to a person in same-day funds on any Business Day at any time shall be considered equivalent to payment to such person in New York Clearing House (next day) funds at the same time on the preceding Business Day, and any payment made after 12:00 noon, Eastern time, on any Business Day shall be considered to have been made instead in the same form of funds and to the same person before 12:00 noon, Eastern time, on the next Business Day.

(ii) The amount of cash dividends per share of AMPS payable (if declared) on the Initial Dividend Payment Date and on each Dividend Payment Date of each 7-Day Dividend Period and each Short Term Dividend Period shall be computed by multiplying the Applicable Rate for such Dividend Period by a fraction, the numerator of which will be the number of days in such Dividend Period or part thereof that such share was outstanding and the denominator of which will be 365, multiplying the amount so obtained by $25,000, and rounding the amount so obtained to the nearest cent. During any Long Term Dividend Period, the amount of cash dividends per share of AMPS payable (if declared) on any Dividend Payment Date shall be computed by multiplying the Applicable Rate for such Dividend Period by a fraction, the numerator of which will be such number of days in such part of such Dividend Period that such share was outstanding and for which dividends are payable on such Dividend Payment Dates and the denominator of which will be 360, multiplying the amount so obtained by $25,000, and rounding the amount so obtained to the nearest cent.

(iii) With respect to each Dividend Period that is a Special Dividend Period, the Corporation may, at its sole option and to the extent permitted by law, by telephonic and written notice (a “Request for Special Dividend Period”) to the Auction Agent and to each Broker-Dealer, request that the next succeeding Dividend Period for the AMPS be a number of days (other than seven), evenly divisible by seven and not fewer than seven nor more than 364 in the case of a Short Term Dividend Period or one whole year or more but not greater than five years in the case of a Long Term Dividend Period, specified in such notice, provided that the Corporation may not give a Request for Special Dividend Period (and any such request shall be null and void) unless, for any

Auction occurring after the initial Auction, Sufficient Clearing Bids were made in the last occurring Auction and unless full cumulative dividends, any amounts due with respect to redemptions, and any Additional Dividends payable prior to such date have been paid in full. Such Request for Special Dividend Period, in the case of a Short Term Dividend Period, shall be given on or prior to the second Business Day but not more than seven Business Days prior to an Auction Date for the AMPS and, in the case of a Long Term Dividend Period, shall be given on or prior to the second Business Day but not more than 28 days prior to an Auction Date for the AMPS. Upon receiving such Request for Special Dividend Period, the Broker-Dealer(s) shall jointly determine whether, given the factors set forth below, it is advisable that the Corporation issue a Notice of Special Dividend Period for the AMPS as contemplated by such Request for Special Dividend Period and the Optional Redemption Price of the AMPS during such Special Dividend Period and the Specific Redemption Provisions and shall give the Corporation written notice (a “Response”) of such determination by no later than the second Business Day prior to such Auction Date. In making such determination the Broker-Dealer(s) will consider (1) existing short-term and long-term market rates and indices of such short-term and long-term rates, (2) existing market supply and demand for short-term and long-term securities, (3) existing yield curves for short-term and long-term securities comparable to the AMPS, (4) industry and financial conditions which may affect the AMPS, (5) the investment objective of the Corporation, and (6) the Dividend Periods and dividend rates at which current and potential beneficial holders of the AMPS would remain or become beneficial holders. If the Broker-Dealer(s) shall not give the Corporation a Response by such second Business Day or if the Response states that given

the factors set forth above it is not advisable that the Corporation give a Notice of Special Dividend Period for the AMPS, the Corporation may not give a Notice of Special Dividend Period in respect of such Request for Special Dividend Period. In the event the Response indicates that it is advisable that the Corporation give a Notice of Special Dividend Period for the AMPS, the Corporation may by no later than the second Business Day prior to such Auction Date give a notice (a “Notice of Special Dividend Period”) to the Auction Agent, the Securities Depository and each Broker-Dealer which notice will specify (i) the duration of the Special Dividend Period, (ii) the Optional Redemption Price as specified in the related Response and (iii) the Specific Redemption Provisions, if any, as specified in the related Response. The Corporation also shall provide a copy of such Notice of Special Dividend Period to Moody’s and S&P. The Corporation shall not give a Notice of Special Dividend Period and, if the Corporation has given a Notice of Special Dividend Period, the Corporation is required to give telephonic and written notice of its revocation (a “Notice of Revocation”) to the Auction Agent, each Broker-Dealer, and the Securities Depository on or prior to the Business Day prior to the relevant Auction Date if (x) either the 1940 Act AMPS Asset Coverage is not satisfied or the Corporation shall fail to maintain S&P Eligible Assets and Moody’s Eligible Assets each with an aggregate Discounted Value at least equal to the AMPS Basic Maintenance Amount, in each case on the Valuation Date immediately preceding the Business Day prior to the relevant Auction Date on an actual basis and on a pro forma basis giving effect to the proposed Special Dividend Period (using as a pro forma dividend rate with respect to such Special Dividend Period the dividend rate which the Broker-Dealers shall advise the Corporation is an approximately equal rate for securities

similar to the AMPS with an equal dividend period), provided that, in calculating the aggregate Discounted Value of Moody’s Eligible Assets for this purpose, the Moody’s Exposure Period shall be deemed to be one week longer, (y) sufficient funds for the payment of dividends payable on the immediately succeeding Dividend Payment Date have not been segregated in an account at the Corporation’s custodian bank or on the books of the Corporation by the close of business on the third Business Day preceding the related Auction Date or (z) the Broker-Dealer(s) jointly advise the Corporation that after consideration of the factors listed above they have concluded that it is advisable to give a Notice of Revocation. The Corporation also shall provide a copy of such Notice of Revocation to Moody’s and S&P. If the Corporation is prohibited from giving a Notice of Special Dividend Period as a result of any of the factors enumerated in clause (x), (y) or (z) above or if the Corporation gives a Notice of Revocation with respect to a Notice of Special Dividend Period for AMPS, the next succeeding Dividend Period will be a 7-Day Dividend Period. In addition, in the event Sufficient Clearing Bids are not made in the applicable Auction or such Auction is not held for any reason, such next succeeding Dividend Period will be a 7-Day Dividend Period and the Corporation may not again give a Notice of Special Dividend Period for the AMPS (and any such attempted notice shall be null and void) until Sufficient Clearing Bids have been made in an Auction with respect to a 7-Day Dividend Period.

(d) (i) Holders shall not be entitled to any dividends, whether payable in cash, property or stock, in excess of full cumulative dividends and applicable late charges, as herein provided, on the shares of AMPS (except for Additional Dividends as provided in paragraph 2(e) hereof and additional payments as provided in paragraph 2(f) hereof). Except for the late charge

payable pursuant to paragraph 2(c)(i) hereof, no interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment on the shares of AMPS that may be in arrears.

(ii) For so long as any share of AMPS is Outstanding, the Corporation 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 options, warrants or rights to subscribe for or purchase, Common Stock or other stock, if any, ranking junior to the shares of AMPS as to dividends or upon liquidation) in respect of the Common Stock or any other stock of the Corporation ranking junior to or on a parity with the shares of AMPS as to dividends or upon liquidation, or call for redemption, redeem, purchase or otherwise acquire for consideration any shares of the Common Stock or any other such junior stock (except by conversion into or exchange for stock of the Corporation ranking junior to the shares of AMPS as to dividends and upon liquidation) or any other such Parity Stock (except by conversion into or exchange for stock of the Corporation ranking junior to or on a parity with the shares of AMPS as to dividends and upon liquidation), unless (A) immediately after such transaction, the Corporation shall have S&P Eligible Assets and Moody’s Eligible Assets each with an aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance Amount and the Corporation shall maintain the 1940 Act AMPS Asset Coverage, (B) full cumulative dividends on shares of AMPS and shares of Other AMPS due on or prior to the date of the transaction have been declared and paid or shall have been declared and sufficient funds for the payment thereof deposited with the Auction Agent, (C) any Additional Dividend required to be paid under paragraph 2(e) below on or before the date of such declaration or payment has been paid and (D) the Corporation has redeemed the full number of shares of AMPS required to be redeemed by any provision for mandatory redemption contained in Section

(e) Each dividend shall consist of (i) cash at the Applicable Rate, (ii) an uncertificated right (a “Right”) to receive an Additional Dividend (as defined below), and (iii) any additional amounts as set forth in paragraph 2(f) below. Each Right shall thereafter be independent of the share or shares of AMPS on which the dividend was paid. The Corporation shall cause to be maintained a record of each Right received by the respective Holders. A Right may not be transferred other than by operation of law. If the Corporation retroactively allocates any net capital gains or other income subject to regular Federal income taxes to shares of AMPS without having given advance notice thereof to the Auction Agent as described in paragraph 2(f) hereof solely by reason of the fact that such allocation is made as a result of the redemption of all or some of the outstanding shares of AMPS or the liquidation of the Corporation (the amount of such allocation referred to herein as a “Retroactive Taxable Allocation”), the Corporation will, within 90 days (and generally within 60 days) after the end of the Corporation’s fiscal year for which a Retroactive Taxable Allocation is made, provide notice thereof to the Auction Agent and to each holder of a Right applicable to such shares of AMPS (initially Cede & Co. as nominee of The Depository Trust Company) during such fiscal year at such holder’s address as the same appears or last appeared on the Stock Books of the Corporation. The Corporation will, within 30 days after such notice is given to the Auction Agent, pay to the Auction Agent (who will then distribute to such holders of Rights), out of funds legally available therefor, an amount equal to the aggregate Additional Dividend with respect to all Retroactive Taxable Allocations made to such holders during the fiscal year in question.

An “Additional Dividend” means payment to a present or former holder of shares of AMPS of an amount which, when taken together with the aggregate amount of Retroactive Taxable Allocations made to such holder with respect to the fiscal year in question, would cause such holder’s dividends in dollars (after Federal income tax consequences) from the aggregate of both the Retroactive Taxable Allocations and the Additional Dividend to be equal to the dollar amount of the dividends which would have been received by such holder if the amount of the aggregate Retroactive Taxable Allocations had been excludable from the gross income of such holder. Such Additional Dividend shall be calculated (i) without consideration being given to the time value of money; (ii) assuming that no holder of shares of AMPS is subject to the Federal alternative minimum tax with respect to dividends received from the Corporation; and (iii) assuming that each Retroactive Taxable Allocation would be taxable in the hands of each holder of shares of AMPS at the greater of: (x) the maximum marginal regular Federal individual income tax rate applicable to ordinary income or capital gains depending on the taxable character of the distribution (including any surtax); or (y) the maximum marginal regular Federal corporate income tax rate applicable to ordinary income or capital gains depending on the taxable character of the distribution (disregarding in both (x) and (y) the effect of any state or local taxes and the phase out of, or provision limiting, personal exemptions, itemized deductions, or the benefit of lower tax brackets).

(f) Except as provided below, whenever the Corporation intends to include any net capital gains or other income subject to regular Federal income taxes in any dividend on shares of AMPS, the Corporation will notify the Auction Agent of the amount to be so included at least five Business Days prior to the Auction Date on which the Applicable Rate for such dividend is to be established. The Corporation may also include such income in a dividend on shares of

AMPS without giving advance notice thereof if it increases the dividend by an additional amount calculated as if such income was a Retroactive Taxable Allocation and the additional amount was an Additional Dividend, provided that the Corporation will notify the Auction Agent of the additional amounts to be included in such dividend at least five Business Days prior to the applicable Dividend Payment Date.

3. Liquidation Rights. Upon any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, the Holders shall be entitled to receive, out of the assets of the Corporation available for distribution to shareholders, before any distribution or payment is made upon any Common Stock or any other capital stock ranking junior in right of payment upon liquidation to the AMPS, the sum of $25,000 per share plus accumulated but unpaid dividends (whether or not earned or declared) thereon to the date of distribution, and after such payment the Holders will be entitled to no other payments other than Additional Dividends as provided in paragraph 2(e) hereof. If upon any liquidation, dissolution or winding up of the Corporation, the amounts payable with respect to the AMPS and any other Outstanding class or series of Preferred Stock of the Corporation ranking on a parity with the AMPS as to payment upon liquidation are not paid in full, the Holders and the holders of such other class or series will share ratably in any such distribution of assets in proportion to the respective preferential amounts to which they are entitled. After payment of the full amount of the liquidating distribution to which they are entitled, the Holders will not be entitled to any further participation in any distribution of assets by the Corporation except for any Additional Dividends. A consolidation, merger or statutory share exchange of the Corporation with or into any other corporation or entity or a sale, whether for cash, shares of stock, securities or properties, of all or substantially all or any part of the assets of the Corporation shall not be deemed or construed to be a liquidation, dissolution or winding up of the Corporation.

(i) Optional Redemption. To the extent permitted under the 1940 Act and Maryland law, upon giving a Notice of Redemption, the Corporation at its option may redeem shares of AMPS, in whole or in part, out of funds legally available therefor, at the Optional Redemption Price per share, on any Dividend Payment Date; provided that no share of AMPS may be redeemed at the option of the Corporation during (A) the Initial Dividend Period with respect to such share or (B) a Non-Call Period to which such share is subject. In addition, holders of AMPS which are redeemed shall be entitled to receive Additional Dividends to the extent provided herein. The Corporation may not give a Notice of Redemption relating to an optional redemption as described in this paragraph 4(a)(i) unless, at the time of giving such Notice of Redemption, the Corporation has available Deposit Securities with maturity or tender dates not later than the day preceding the applicable redemption date and having a value not less than the amount due to Holders by reason of the redemption of their shares of AMPS on such redemption date.

(ii) Mandatory Redemption. The Corporation shall redeem, out of funds legally available therefor, at the Mandatory Redemption Price per share, shares of AMPS to the extent permitted under the 1940 Act and Maryland law, on a date fixed by the Board of Directors, if the Corporation fails to maintain S&P Eligible Assets and Moody’s Eligible Assets each with an aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance Amount as provided in paragraph 7(a) or to satisfy the 1940 Act AMPS

Asset Coverage as provided in paragraph 6 and such failure is not cured on or before the AMPS Basic Maintenance Cure Date or the 1940 Act Cure Date (herein collectively referred to as a “Cure Date”), as the case may be. In addition, holders of AMPS so redeemed shall be entitled to receive Additional Dividends to the extent provided herein. The number of shares of AMPS to be redeemed shall be equal to the lesser of (i) the minimum number of shares of AMPS the redemption of which, if deemed to have occurred immediately prior to the opening of business on the Cure Date, together with all shares of other Preferred Stock subject to redemption or retirement, would result in the Corporation having S&P Eligible Assets and Moody’s Eligible Assets each with an aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance Amount or satisfaction of the 1940 Act AMPS Asset Coverage, as the case may be, on such Cure Date (provided that, if there is no such minimum number of shares of AMPS and shares of other Preferred Stock the redemption of which would have such result, all shares of AMPS and shares of other Preferred Stock then Outstanding shall be redeemed), and (ii) the maximum number of shares of AMPS, together with all shares of other Preferred Stock subject to redemption or retirement, that can be redeemed out of funds expected to be legally available therefor on such redemption date. In determining the number of shares of AMPS required to be redeemed in accordance with the foregoing, the Corporation shall allocate the number required to be redeemed which would result in the Corporation having S&P Eligible Assets and Moody’s Eligible Assets each with an aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance Amount or satisfaction of the 1940 Act AMPS Asset Coverage, as the case may be, pro rata among shares of AMPS, Other AMPS and other Preferred Stock subject

to redemption pursuant to provisions similar to those contained in this paragraph 4(a)(ii); provided that, shares of AMPS which may not be redeemed at the option of the Corporation due to the designation of a Non-Call Period applicable to such shares (A) will be subject to mandatory redemption only to the extent that other shares are not available to satisfy the number of shares required to be redeemed and (B) will be selected for redemption in an ascending order of outstanding number of days in the Non-Call Period (with shares with the lowest number of days to be redeemed first) and by lot in the event of shares having an equal number of days in such Non-Call Period. The Corporation shall effect such redemption on a Business Day which is not later than 30 days after such Cure Date, except that if the Corporation does not have funds legally available for the redemption of all of the required number of shares of AMPS and shares of other Preferred Stock which are subject to mandatory redemption or the Corporation otherwise is unable to effect such redemption on or prior to 30 days after such Cure Date, the Corporation shall redeem those shares of AMPS which it is unable to redeem on the earliest practicable date on which it is able to effect such redemption out of funds legally available therefor.

(b) No Redemption Under Certain Circumstances. Notwithstanding any other provision of this paragraph 4, no shares of AMPS may be redeemed pursuant to paragraph 4(a)(i) of these Articles Supplementary (i) unless all dividends in arrears on all remaining outstanding shares of Parity Stock shall have been or are being contemporaneously paid or declared and set apart for payment and (ii) if redemption thereof would result in the Corporation’s failure to maintain Moody’s Eligible Assets or S&P Eligible Assets with an aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance Amount. In the event that less than all the

outstanding shares of a series of AMPS are to be redeemed and there is more than one Holder, the shares of that series of AMPS to be redeemed shall be selected by lot or such other method as the Corporation shall deem fair and equitable.

(c) Notice of Redemption. Whenever shares of AMPS are to be redeemed, the Corporation, not less than 17 nor more than 60 days prior to the date fixed for redemption, shall mail a notice (“Notice of Redemption”) by first-class mail, postage prepaid, to each Holder of shares of AMPS to be redeemed and to the Auction Agent. The Corporation shall cause the Notice of Redemption to also be published in the eastern and national editions of The Wall Street Journal. The Notice of Redemption shall set forth (i) the redemption date, (ii) the amount of the redemption price, (iii) the aggregate number of shares of AMPS to be redeemed, (iv) the place or places where shares of AMPS are to be surrendered for payment of the redemption price, (v) a statement that dividends on the shares to be redeemed shall cease to accumulate on such redemption date (except that holders may be entitled to Additional Dividends) and (vi) the provision of these Articles Supplementary pursuant to which such shares are being redeemed. No defect in the Notice of Redemption or in the mailing or publication thereof shall affect the validity of the redemption proceedings, except as required by applicable law.

If the Notice of Redemption shall have been given as aforesaid and, concurrently or thereafter, the Corporation shall have deposited in trust with the Auction Agent, or segregated in an account at the Corporation’s custodian bank for the benefit of the Holders of the AMPS to be redeemed and for payment to the Auction Agent, Deposit Securities (with a right of substitution) having an aggregate Discounted Value equal to the redemption payment for the shares of AMPS as to which such Notice of Redemption has been given with irrevocable instructions and authority to pay the redemption price to the Holders of such shares, then upon the date of such

deposit or, if no such deposit is made, then upon such date fixed for redemption (unless the Corporation shall default in making the redemption payment), all rights of the Holders of such shares as shareholders of the Corporation by reason of the ownership of such shares will cease and terminate (except their right to receive the redemption price in respect thereof and any Additional Dividends, but without interest), and such shares shall no longer be deemed outstanding. The Corporation shall be entitled to receive, from time to time, from the Auction Agent the interest, if any, on such Deposit Securities deposited with it and the Holders of any shares so redeemed shall have no claim to any of such interest. In case the Holder of any shares so called for redemption shall not claim the redemption payment for his shares within one year after the date of redemption, the Auction Agent shall, upon demand, pay over to the Corporation such amount remaining on deposit and the Auction Agent shall thereupon be relieved of all responsibility to the Holder of such shares called for redemption and such Holder thereafter shall look only to the Corporation for the redemption payment.

(a) General. Except as otherwise provided in the Charter or By-laws, each Holder of shares of AMPS shall be entitled to one vote for each share held on each matter submitted to a vote of shareholders of the Corporation, and the holders of outstanding shares of Preferred Stock, including AMPS, and of shares of Common Stock shall vote together as a single class; provided that, at any meeting of the shareholders of the Corporation held for the election of directors, the holders of outstanding shares of Preferred Stock, including AMPS, shall be entitled, as a class, to the exclusion of the holders of all other securities and classes of capital stock of the Corporation, to elect two directors of the Corporation. Subject to paragraph 5(b) hereof, the holders of outstanding shares of capital stock of the Corporation, including the holders of outstanding shares of Preferred Stock, including AMPS, voting as a single class, shall elect the balance of the directors.

(b) Right to Elect Majority of Board of Directors. During any period in which any one or more of the conditions described below shall exist (such period being referred to herein as a “Voting Period”), the number of directors constituting the Board of Directors shall be automatically increased by the smallest number that, when added to the two directors elected exclusively by the holders of shares of Preferred Stock, would constitute a majority of the Board of Directors as so increased by such smallest number; and the holders of shares of Preferred Stock shall be entitled, voting separately as one class (to the exclusion of the holders of all other securities and classes of capital stock of the Corporation), to elect such smallest number of additional directors, together with the two directors that such holders are in any event entitled to elect. A Voting Period shall commence:

(i) if at any time accumulated dividends (whether or not earned or declared, and whether or not funds are then legally available in an amount sufficient therefor) on the outstanding shares of AMPS equal to at least two full years’ dividends shall be due and unpaid and sufficient cash or specified securities shall not have been deposited with the Auction Agent for the payment of such accumulated dividends; or

(ii) if at any time holders of any other shares of Preferred Stock are entitled to elect a majority of the directors of the Corporation under the 1940 Act.

Upon the termination of a Voting Period, the voting rights described in this paragraph 5(b) shall cease, subject always, however, to the reverting of such voting rights in the Holders upon the further occurrence of any of the events described in this paragraph 5(b).

(c) Right to Vote with Respect to Certain Other Matters. So long as any shares of AMPS are outstanding, the Corporation shall not, without the affirmative vote of the holders of a majority of the shares of Preferred Stock Outstanding at the time, voting separately as one class: (i) authorize, create or issue any class or series of stock ranking prior to the AMPS or any other series of Preferred Stock with respect to payment of dividends or the distribution of assets on dissolution, liquidation or winding up the affairs of the Corporation, or (ii) amend, alter or repeal the provisions of the Charter, whether by merger, consolidation or otherwise, so as to adversely affect any of the contract rights expressly set forth in the Charter of holders of shares of AMPS or any other Preferred Stock. To the extent permitted under the 1940 Act, in the event shares of more than one series of Preferred Stock are outstanding, the Corporation shall not approve any of the actions set forth in clause (i) or (ii) which adversely affects the contract rights expressly set forth in the Charter of a Holder of shares of AMPS differently than those of a Holder of shares of any other series of Preferred Stock without the affirmative vote of the holders of at least a majority of the shares of AMPS adversely affected and outstanding at such time (voting separately as a class). The Corporation shall notify Moody’s and S&P ten Business Days prior to any such vote described in clause (i) or (ii). Unless a higher percentage is provided for under the Charter, the affirmative vote of the holders of a majority of the outstanding shares of Preferred Stock, including AMPS, voting together as a single class, will be required to approve any plan of reorganization (including bankruptcy proceedings) adversely affecting such shares or any action requiring a vote of security holders under Section 13(a) of the 1940 Act. So long as any shares of the AMPS are outstanding, the affirmative vote of the holders of a majority of the outstanding shares of Preferred Stock, including AMPS, voting together as a single class, will be required to approve any voluntary application by the Corporation for relief under Federal

bankruptcy law or any similar application under state law for so long as the Corporation is solvent and does not foresee becoming insolvent. For purposes of the two preceding sentences, the phrase “vote of the holders of a majority of the outstanding shares of Preferred Stock” shall have the meaning set forth in the 1940 Act. The class vote of holders of shares of Preferred Stock, including AMPS, described above will in each case be in addition to a separate vote of the requisite percentage of shares of Common Stock and shares of Preferred Stock, including AMPS, voting together as a single class necessary to authorize the action in question. An increase in the number of authorized shares of Preferred Stock pursuant to the Charter or the issuance of additional shares of any series of Preferred Stock (including AMPS and Other AMPS) pursuant to the Charter shall not in and of itself be considered to adversely affect the contract rights of the holders of the AMPS.

Notwithstanding the foregoing, and except as otherwise required by the 1940 Act, (i) holders of outstanding shares of the AMPS will be entitled as a series, to the exclusion of the holders of all other securities, including other Preferred Stock, Common Stock and other classes of capital stock of the Corporation, to vote on matters affecting the AMPS that do not materially adversely affect any of the contract rights of holders of such other securities, including other Preferred Stock, Common Stock and other classes of capital stock, as expressly set forth in the Charter, and (ii) holders of outstanding shares of AMPS will not be entitled to vote on matters affecting any other Preferred Stock that do not materially adversely affect any of the contract rights of holders of the AMPS, as expressly set forth in the Charter.

(i) As soon as practicable after the accrual of any right of the holders of shares of Preferred Stock to elect additional directors as described in paragraph 5(b) above, the

Corporation shall call a special meeting of such holders and instruct the Auction Agent to mail a notice of such special meeting to such holders, such meeting to be held not less than 10 nor more than 20 days after the date of mailing of such notice. If the Corporation fails to send such notice to the Auction Agent or if the Corporation does not call such a special meeting, 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 the close of business on the fifth Business Day preceding the day on which such notice is mailed. At any such special meeting and at each meeting held during a Voting Period, such Holders, voting together as a class (to the exclusion of the holders of all other securities and classes of capital stock of the Corporation), shall be entitled to elect the number of directors prescribed in paragraph 5(b) above. At any such meeting or adjournment thereof in the absence of a quorum, a majority of such holders present in person or by proxy shall have the power to adjourn the meeting without notice, other than by an announcement at the meeting, to a date not more than 120 days after the original record date.

(ii) For purposes of determining any rights of the Holders to vote on any matter or the number of shares required to constitute a quorum, whether such right is created by these Articles Supplementary, by the other provisions of the Charter, by statute or otherwise, a share of AMPS which is not Outstanding shall not be counted.

(iii) The terms of office of all persons who are directors of the Corporation at the time of a special meeting of Holders and holders of other Preferred Stock to elect directors shall continue, notwithstanding the election at such meeting by the Holders and such other holders of the number of directors that they are entitled to elect, and the

persons so elected by the Holders and such other holders, together with the two incumbent directors elected by the Holders and such other holders of Preferred Stock and the remaining incumbent directors elected by the holders of the Common Stock and Preferred Stock, shall constitute the duly elected directors of the Corporation.

(iv) Simultaneously with the expiration of a Voting Period, the terms of office of the additional directors elected by the Holders and holders of other Preferred Stock pursuant to paragraph 5(b) above shall terminate, the remaining directors shall constitute the directors of the Corporation and the voting rights of the Holders and such other holders to elect additional directors pursuant to paragraph 5(b) above shall cease, subject to the provisions of the last sentence of paragraph 5(b).

(e) Exclusive Remedy. Unless otherwise required by law, the Holders of shares of AMPS shall not have any rights or preferences other than those specifically set forth herein. The Holders of shares of AMPS shall have no preemptive rights or rights to cumulative voting. In the event that the Corporation fails to pay any dividends on the shares of AMPS, the exclusive remedy of the Holders shall be the right to vote for directors pursuant to the provisions of this paragraph 5.

(f) Notification to S&P and Moody’s. In the event a vote of Holders of AMPS is required pursuant to the provisions of Section 13(a) of the 1940 Act, the Corporation shall, not later than ten Business Days prior to the date on which such vote is to be taken, notify S&P and Moody’s that such vote is to be taken and the nature of the action with respect to which such vote is to be taken and, not later than ten Business Days after the date on which such vote is taken, notify S&P and Moody’s of the result of such vote.

6. 1940 Act AMPS Asset Coverage. The Corporation shall maintain, as of the last Business Day of each month in which any share of AMPS is outstanding, the 1940 Act AMPS Asset Coverage.

(a) The Corporation shall maintain, on each Valuation Date, and shall verify to its satisfaction that it is maintaining on such Valuation Date, (i) S&P Eligible Assets having an aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance Amount and (ii) Moody’s Eligible Assets having an aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance Amount. Upon any failure to maintain the required Discounted Value, the Corporation will use its best efforts to alter the composition of its portfolio to reattain a Discounted Value at least equal to the AMPS Basic Maintenance Amount on or prior to the AMPS Basic Maintenance Cure Date.

(b) On or before 5:00 p.m., Eastern time, on the seventh Business Day in the case of Moody’s and on the next Business Day in the case of S&P, after a Valuation Date on which the Corporation fails to satisfy the AMPS Basic Maintenance Amount, the Corporation shall (i) complete and deliver to Moody’s a complete AMPS Basic Maintenance Report as of the date of such failure and (ii) send S&P an electronic notification of such failure. The Corporation will (i) deliver an AMPS Basic Maintenance Report to Moody’s and (ii) send S&P an electronic notification on or before 5:00 p.m., Eastern time, on the seventh Business Day in the case of Moody’s and on the next Business Day in the case of S&P, after a Valuation Date on which the Corporation cures its failure to maintain Moody’s Eligible Assets or S&P Eligible Assets, as the case may be, with an aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance Amount and on which the Corporation fails to maintain Moody’s Eligible Assets or

S&P Eligible Assets, as the case may be, with an aggregate Discounted Value which exceeds the AMPS Basic Maintenance Amount by 10% or more in the case of S&P and 25% or more in the case of Moody’s. The Corporation will also deliver an AMPS Basic Maintenance Report to Moody’s and S&P as of the last Business Day of each month on or before the seventh Business Day after such date. The Corporation shall also provide Moody’s and S&P with an AMPS Basic Maintenance Report when specifically requested by either Moody’s or S&P. A failure by the Corporation to deliver an AMPS Basic Maintenance Report under this paragraph 7(b) shall be deemed to be delivery of an AMPS Basic Maintenance Report indicating the Discounted Value for S&P Eligible Assets and Moody’s Eligible Assets of the Corporation is less than the AMPS Basic Maintenance Amount, as of the relevant Valuation Date.

(c) Within ten Business Days after the date of delivery of an AMPS Basic Maintenance Report in accordance with paragraph 7(b) above relating to the month in which the Corporation’s fiscal year ends, the Independent Auditors will confirm in writing to S&P and Moody’s (i) the mathematical accuracy of the calculations reflected in such Report, (ii) that, in such Report, the Corporation correctly determined the assets of the Corporation which constitute S&P Eligible Assets or Moody’s Eligible Assets, as the case may be, at its fiscal year end in accordance with these Articles Supplementary, and (iii) that, in such Report, the Corporation determined whether the Corporation had, at its fiscal year end in accordance with these Articles Supplementary, S&P Eligible Assets of an aggregate Discounted Value at least equal to the AMPS Basic Maintenance Amount and Moody’s Eligible Assets of an aggregate Discounted Value at least equal to the AMPS Basic Maintenance Amount (such confirmation is herein called the “Auditors’ Confirmation”).

(d) Within ten Business Days after the date of delivery to Moody’s of an AMPS Basic Maintenance Report in accordance with paragraph 7(b) above relating to any Valuation Date on which the Corporation failed to maintain S&P Eligible Assets with an aggregate Discounted Value and Moody’s Eligible Assets with an aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance Amount, and relating to the AMPS Basic Maintenance Cure Date with respect to such failure, the Independent Auditors will provide to S&P and Moody’s an Auditors’ Confirmation as to such AMPS Basic Maintenance Report.

(e) If any Auditors’ Confirmation delivered pursuant to subparagraph (c) or (d) of this paragraph 7 shows that an error was made in the AMPS Basic Maintenance Report for a particular date for which such Auditors’ Confirmation as required to be delivered, or shows that a lower aggregate Discounted Value for the aggregate of all S&P Eligible Assets or Moody’s Eligible Assets, as the case may be, of the Corporation was determined by the Independent Auditors, the calculation or determination made by such Independent Auditors shall be final and conclusive and shall be binding on the Corporation, and the Corporation shall accordingly amend and deliver the AMPS Basic Maintenance Report to S&P and Moody’s promptly following receipt by the Corporation of such Auditors’ Confirmation.

(f) On or before 5:00 p.m., Eastern time, on the first Business Day after the Date of Original Issue of the shares of AMPS, the Corporation will complete and deliver to S&P and Moody’s an AMPS Basic Maintenance Report as of the close of business on such Date of Original Issue. Within five Business Days of such Date of Original Issue, the Independent Auditors will confirm in writing to S&P and Moody’s (i) the mathematical accuracy of the calculations reflected in such Report and (ii) that the aggregate Discounted Value of S&P Eligible Assets and the aggregate Discounted Value of Moody’s Eligible Assets reflected thereon

equals or exceeds the AMPS Basic Maintenance Amount reflected thereon. Also, on or before 5:00 p.m., Eastern time, on the first Business Day after shares of Common Stock are repurchased by the Corporation, the Corporation will complete and deliver to S&P and Moody’s an AMPS Basic Maintenance Report as of the close of business on such date that Common Stock is repurchased.

(g) For so long as shares of AMPS are rated by Moody’s, in managing the Corporation’s portfolio, the Adviser will not alter the composition of the Corporation’s portfolio if, in the reasonable belief of the Adviser, the effect of any such alteration would be to cause the Corporation to have Moody’s Eligible Assets with an aggregate Discounted Value, as of the immediately preceding Valuation Date, less than the AMPS Basic Maintenance Amount as of such Valuation Date; provided, however, that in the event that, as of the immediately preceding Valuation Date, the aggregate Discounted Value of Moody’s Eligible Assets exceeded the AMPS Basic Maintenance Amount by five percent or less, the Adviser will not alter the composition of the Corporation’s portfolio in a manner reasonably expected to reduce the aggregate Discounted Value of Moody’s Eligible Assets unless the Corporation shall have confirmed that, after giving effect to such alteration, the aggregate Discounted Value of Moody’s Eligible Assets would exceed the AMPS Basic Maintenance Amount.

(a) For so long as any shares of AMPS are rated by S&P, the Corporation will not purchase or sell futures contracts, write, purchase or sell options on futures contracts or write put options (except covered put options) or call options (except covered call options) on portfolio securities unless it receives written confirmation from S&P that engaging in such transactions will not impair the ratings then assigned to the shares of AMPS by S&P, except that the

Corporation may purchase or sell futures contracts based on the Bond Buyer Municipal Bond Index (the “Municipal Index”) or Treasury Bonds and write, purchase or sell put and call options on such contracts (collectively, “S&P Hedging Transactions”), subject to the following limitations:

(i) the Corporation will not engage in any S&P Hedging Transaction based on the Municipal Index (other than transactions which terminate a futures contract or option held by the Corporation by the Corporation’s taking an opposite position thereto (“Closing Transactions”)), which would cause the Corporation at the time of such transaction to own or have sold the least of (A) more than 1,000 outstanding futures contracts based on the Municipal Index, (B) outstanding futures contracts based on the Municipal Index exceeding in number 25% of the quotient of the Market Value of the Corporation’s total assets divided by $1,000 or (C) outstanding futures contracts based on the Municipal Index exceeding in number 10% of the average number of daily traded futures contracts based on the Municipal Index in the 30 days preceding the time of effecting such transaction as reported by The Wall Street Journal;

(ii) the Corporation will not engage in any S&P Hedging Transaction based on Treasury Bonds (other than Closing Transactions) which would cause the Corporation at the time of such transaction to own or have sold the lesser of (A) outstanding futures contracts based on Treasury Bonds exceeding in number 50% of the quotient of the Market Value of the Corporation’s total assets divided by $100,000 ($200,000 in the case of the two-year United States Treasury Note) or (B) outstanding futures contracts based on Treasury Bonds exceeding in number 10% of the average number of daily traded futures contracts based on Treasury Bonds in the 30 days preceding the time of effecting such transaction as reported by The Wall Street Journal;

(iii) the Corporation will engage in Closing Transactions to close out any outstanding futures contract which the Corporation owns or has sold or any outstanding option thereon owned by the Corporation in the event (A) the Corporation does not have S&P Eligible Assets with an aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance Amount on two consecutive Valuation Dates and (B) the Corporation is required to pay Variation Margin on the second such Valuation Date;

(iv) the Corporation will engage in a Closing Transaction to close out any outstanding futures contract or option thereon in the month prior to the delivery month under the terms of such futures contract or option thereon unless the Corporation holds the securities deliverable under such terms; and

(v) when the Corporation writes a futures contract or option thereon, it will either maintain an amount of cash, cash equivalents or liquid assets in a segregated account with the Corporation’s custodian, so that the amount so segregated plus the amount of Initial Margin and Variation Margin held in the account of or on behalf of the Corporation’s broker with respect to such futures contract or option equals the Market Value of the futures contract or option, or, in the event the Corporation writes a futures contract or option thereon which requires delivery of an underlying security, it shall hold such underlying security in its portfolio.

For purposes of determining whether the Corporation has S&P Eligible Assets with a Discounted Value that equals or exceeds the AMPS Basic Maintenance Amount, the Discounted Value of cash or securities held for the payment of Initial Margin or Variation Margin shall be

zero and the aggregate Discounted Value of S&P Eligible Assets shall be reduced by an amount equal to (i) 30% of the aggregate settlement value, as marked to market, of any outstanding futures contracts based on the Municipal Index which are owned by the Corporation plus (ii) 25% of the aggregate settlement value, as marked to market, of any outstanding futures contracts based on Treasury Bonds which contracts are owned by the Corporation.

(b) For so long as any shares of AMPS are rated by Moody’s, the Corporation will not engage in Bond Market Association Municipal Swap Index swap transactions (“BMA swap transactions”), buy or sell futures contracts, write, purchase or sell call options on futures contracts or purchase put options on futures contracts or write call options (except covered call options) on portfolio securities unless it receives written confirmation from Moody’s that engaging in such transactions would not impair the ratings then assigned to the shares of AMPS by Moody’s, except that the Corporation may engage in BMA swap transactions, purchase or sell exchange-traded futures contracts based on any index approved by Moody’s or Treasury Bonds and purchase, write or sell exchange-traded put options on such futures contracts (collectively, “Moody’s Hedging Transactions”), subject to the following limitations:

(i) the Corporation will not engage in any Moody’s Hedging Transaction based on the Municipal Index (other than Closing Transactions) which would cause the Corporation at the time of such transaction to own or have sold (A) outstanding futures contracts based on the Municipal Index exceeding in number 10% of the average number of daily traded futures contracts based on the Municipal Index in the 30 days preceding the time of effecting such transaction as reported by The Wall Street Journal or (B) outstanding futures contracts based on the Municipal Index having a Market Value exceeding 50% of the Market Value of all Municipal Bonds constituting Moody’s Eligible Assets owned by the Corporation (other than Moody’s Eligible Assets already subject to a Moody’s Hedging Transaction);

(ii) the Corporation will not engage in any Moody’s Hedging Transaction based on Treasury Bonds (other than Closing Transactions) which would cause the Corporation at the time of such transaction to own or have sold (A) outstanding futures contracts based on Treasury Bonds having an aggregate Market Value exceeding 40% of the aggregate Market Value of Moody’s Eligible Assets owned by the Corporation and rated Aa by Moody’s (or, if not rated by Moody’s but rated by S&P, rated AAA by S&P) or (B) outstanding futures contracts based on Treasury Bonds having an aggregate Market Value exceeding 80% of the aggregate Market Value of all Municipal Bonds constituting Moody’s Eligible Assets owned by the Corporation (other than Moody’s Eligible Assets already subject to a Moody’s Hedging Transaction) and rated Baa or A by Moody’s (or, if not rated by Moody’s but rated by S&P, rated A or AA by S&P) (for purposes of the foregoing clauses (i) and (ii), the Corporation shall be deemed to own the number of futures contracts that underlie any outstanding options written by the Corporation);

(iii) the Corporation will engage in Closing Transactions to close out any outstanding futures contract based on the Municipal Index if the amount of open interest in the Municipal Index as reported by The Wall Street Journal is less than 5,000;

(iv) the Corporation will engage in a Closing Transaction to close out any outstanding futures contract by no later than the fifth Business Day of the month in which such contract expires and will engage in a Closing Transaction to close out any outstanding option on a futures contract by no later than the first Business Day of the month in which such option expires;

(v) the Corporation will engage in Moody’s Hedging Transactions only with respect to futures contracts or options thereon having the next settlement date or the settlement date immediately thereafter;

(vi) the Corporation (A) will not engage in options and futures transactions for leveraging or speculative purposes, except that the Corporation may engage in an option or futures transaction so long as the combination of the Corporation’s non-derivative positions, together with the relevant option or futures transaction, produces a synthetic investment position, or the same economic result, that could be achieved by an investment, consistent with the Corporation’s investment objective and policies, in a security that is not an option or futures transaction, subject to the Adviser periodically demonstrating to Moody’s that said economic results are achieved, and (B) will not write any call options or sell any futures contracts for the purpose of hedging the anticipated purchase of an asset prior to completion of such purchase;

(vii) the Corporation will not enter into an option or futures transaction unless, after giving effect thereto, the Corporation would continue to have Moody’s Eligible Assets with an aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance Amount; and

(viii) the Corporation will not engage in BMA swap transactions with respect to more than 20% of the Corporation’s net assets; provided that the Corporation’s use of futures will proportionately decrease as the Corporation’s use of BMA swap transactions increases, and vice-versa.

For purposes of determining whether the Corporation has Moody’s Eligible Assets with an aggregate Discounted Value that equals or exceeds the AMPS Basic Maintenance Amount,

the Discounted Value of Moody’s Eligible Assets which the Corporation is obligated to deliver or receive pursuant to an outstanding futures contract or option shall be as follows: (i) assets subject to call options written by the Corporation which are either exchange-traded and “readily reversible” or which expire within 49 days after the date as of which such valuation is made shall be valued at the lesser of (a) Discounted Value and (b) the exercise price of the call option written by the Corporation; (ii) assets subject to call options written by the Corporation not meeting the requirements of clause (i) of this sentence shall have no value; (iii) assets subject to put options written by the Corporation shall be valued at the lesser of (A) the exercise price and (B) the Discounted Value of the subject security; (iv) futures contracts shall be valued at the lesser of (A) settlement price and (B) the Discounted Value of the subject security, provided that, if a contract matures within 49 days after the date as of which such valuation is made, where the Corporation is the seller the contract may be valued at the settlement price and where the Corporation is the buyer the contract may be valued at the Discounted Value of the subject securities; and (v) where delivery may be made to the Corporation with any security of a class of securities, the Corporation shall assume that it will take delivery of the security with the lowest Discounted Value.

For purposes of determining whether the Corporation has Moody’s Eligible Assets with an aggregate Discounted Value that equals or exceeds the AMPS Basic Maintenance Amount, the following amounts shall be subtracted from the aggregate Discounted Value of the Moody’s Eligible Assets held by the Corporation: (i) 10% of the exercise price of a written call option; (ii) the exercise price of any written put option; (iii) where the Corporation is the seller under a futures contract, 10% of the settlement price of the futures contract; (iv) where the Corporation is the purchaser under a futures contract, the settlement price of assets purchased under such

futures contract; (v) the settlement price of the underlying futures contract if the Corporation writes put options on a futures contract; and (vi) 105% of the Market Value of the underlying futures contracts if the Corporation writes call options on a futures contract and does not own the underlying contract.

(c) For so long as any shares of AMPS are rated by Moody’s, the Corporation will not enter into any contract to purchase securities for a fixed price at a future date beyond customary settlement time (other than such contracts that constitute Moody’s Hedging Transactions that are permitted under paragraph 8(b) of these Articles Supplementary), except that the Corporation may enter into such contracts to purchase newly-issued securities on the date such securities are issued (“Forward Commitments”), subject to the following limitations:

(i) the Corporation will maintain in a segregated account with its custodian cash, cash equivalents or short-term, fixed-income securities rated P-1, MIG-1 or VMIG-1 by Moody’s and maturing prior to the date of the Forward Commitment with a Market Value that equals or exceeds the amount of the Corporation’s obligations under any Forward Commitments to which it is from time to time a party or long-term, fixed-income securities with a Discounted Value that equals or exceeds the amount of the Corporation’s obligations under any Forward Commitment to which it is from time to time a party; and

(ii) the Corporation will not enter into a Forward Commitment unless, after giving effect thereto, the Corporation would continue to have Moody’s Eligible Assets with an aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance Amount.

(d) For purposes of determining whether the Corporation has Moody’s Eligible Assets with an aggregate Discounted Value that equals or exceeds the AMPS Basic Maintenance Amount, the Discounted Value of all Forward Commitments to which the Corporation is a party and of all securities deliverable to the Corporation pursuant to such Forward Commitments shall be zero.

(e) For so long as shares of AMPS are rated by S&P or Moody’s, the Corporation will not, unless it has received written confirmation from S&P and/or Moody’s, as the case may be, that such action would not impair the ratings then assigned to shares of AMPS by S&P and/or Moody’s, as the case may be, (i) borrow money except for the purpose of clearing transactions in portfolio securities (which borrowings shall under any circumstances be limited to the lesser of $10 million and an amount equal to 5% of the Market Value of the Corporation’s assets at the time of such borrowings and which borrowings shall be repaid within 60 days and not be extended or renewed and shall not cause the aggregate Discounted Value of Moody’s Eligible Assets and S&P Eligible Assets to be less than the AMPS Basic Maintenance Amount), (ii) engage in short sales of securities, (iii) lend any securities, (iv) issue any class or series of stock ranking prior to or on a parity with the AMPS with respect to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up of the Corporation, (v) reissue any AMPS previously purchased or redeemed by the Corporation, (vi) merge or consolidate into or with any other corporation or entity, (vii) change the Pricing Service or (viii) engage in reverse repurchase agreements.

(f) For as long as the AMPS are rated by S&P, the Corporation will not, unless it has received written confirmation from S&P that such action would not impair the rating then assigned to the shares of AMPS by S&P, engage in interest rate swaps, caps and floors, except

that the Corporation may, without obtaining the written consent described above, engage in swaps, caps and floors if: (i) the counterparty to the swap transaction has a short-term rating of A-1 or, if the counterparty does not have a short-term rating, the counterparty’s senior unsecured long-term debt rating is A- or higher, (ii) the original aggregate notional amount of the interest rate swap transaction or transactions is not to be greater than the liquidation preference of the AMPS, (iii) the interest rate swap transaction will be marked-to-market weekly by the swap counterparty, (iv) if the Corporation fails to maintain an aggregate discounted value at least equal to the AMPS Basic Maintenance Amount on two consecutive Valuation Dates then the agreement shall terminate immediately, (v) for the purpose of calculating the Discounted Value of S&P Eligible Assets, 90% of any positive mark-to-market valuation of the Corporation’s rights will be S&P Eligible Assets, 100% of any negative mark-to-market valuation of the Corporation’s rights will be included in the calculation of the AMPS Basic Maintenance Amount, and (vi) the Corporation must maintain liquid assets with a value at least equal to the net amount of the excess, if any, of the Corporation’s obligations over its entitlement with respect to each swap. For caps/floors, the Corporation must maintain liquid assets with a value at least equal to the Corporation’s obligations with respect to such caps or floors.

(g) For so long as shares of AMPS are rated by S&P or Moody’s, as the case may be, the Corporation agrees to provide S&P and/or Moody’s with the following, unless the Corporation has received written confirmation from S&P and/or Moody’s, as the case may be, that the provision of such information is no longer required and that the current rating then assigned to the shares of AMPS by S&P and/or Moody’s, as the case may be, would not be impaired: a notification letter at least 30 days prior to any material change in the Charter; a copy of the AMPS Basic Maintenance Report prepared by the Corporation in accordance with these Articles

Supplementary; and a notice upon the occurrence of any of the following events: (i) any failure by the Corporation to declare or pay any dividends on the AMPS or successfully remarket the AMPS; (ii) any mandatory or optional redemption of the AMPS effected by the Corporation; (iii) any assumption of control of the Board of Directors of the Corporation by the holders of the AMPS; (iv) a general unavailability of dealer quotes on the assets of the Corporation; (v) any material auditor discrepancies on valuations; (vi) the occurrence of any Special Dividend Period; (vii) any change in the Maximum Applicable Rate or the Reference Rate; (viii) the acquisition by any person of beneficial ownership of more than 5% of the Corporation’s voting stock (inclusive of Common Stock and Preferred Stock); (ix) the occurrence of any change in Internal Revenue Service rules with respect to the payment of Additional Dividends; (x) any change in the Pricing Service employed by the Corporation; (xi) any change in the Adviser; (xii) any increase of greater than 40% to the maximum marginal Federal income tax rate applicable to individuals or corporations; and (xiii) the maximum marginal Federal income tax rate applicable to individuals or corporations is increased to a rate in excess of 50%.

(h) For so long as shares of AMPS are rated by S&P or Moody’s, the Corporation shall provide S&P and/or Moody’s with a copy of the Corporation’s annual audited financial statements as soon as practicable (not later than 60 days) after such annual audited financial statements have been made available to the Corporation’s stockholders.

9. Notice. All notices or communications, unless otherwise specified in the By-laws of the Corporation or these Articles Supplementary, shall be sufficiently given if in writing and delivered in person or mailed by first-class mail, postage prepaid. Notice shall be deemed given on the earlier of the date received or the date seven days after which such notice is mailed.

(a) Certain definitions. As used in this paragraph 10, the following terms shall have the following meanings, unless the context otherwise requires:

(i) “AMPS” means the shares of AMPS being auctioned pursuant to this paragraph 10.

(ii) “Auction Date” means the first Business Day preceding the first day of a Dividend Period.

(iii) “Available AMPS” has the meaning specified in paragraph 10(d)(i) below.

(vii) “Maximum Applicable Rate” for any Dividend Period will be the higher of the Applicable Percentage of the Reference Rate or the Applicable Spread plus the Reference Rate. The Applicable Percentage and Applicable Spread will be determined based on (i) the lower of the credit rating or ratings assigned on such date to such shares by Moody’s and S&P (or if Moody’s or S&P or both shall not make such rating available, the equivalent of either or both of such ratings by a Substitute Rating Agency or two Substitute Rating Agencies or, in the event that only one such rating shall be available, such rating) and (ii) whether the Corporation has provided notification to the Auction Agent prior to the Auction establishing the Applicable Rate for any dividend pursuant to paragraph 2(f) hereof that net capital gains or other taxable income will be included in such dividend on shares of AMPS as follows:

The Applicable Percentage and the Applicable Spread as so determined may be further subject to upward but not downward adjustment in the discretion of the Board of Directors of the Corporation after consultation with the Broker-Dealers, provided that immediately following any such increase the Corporation would be in compliance with the AMPS Basic Maintenance Amount. Subject to the provisions of paragraph 12, the Corporation shall take all reasonable action necessary to enable S&P and Moody’s to provide a rating for the AMPS. If either S&P or Moody’s shall not make such a rating available, or neither S&P nor Moody’s shall make such a rating available, subject to the provisions of paragraph 12, Merrill Lynch, Pierce, Fenner & Smith Incorporated or its affiliates and successors, after obtaining the Corporation’s approval, shall select a NRSRO or two NRSROs to act as a Substitute Rating Agency or Substitute Rating Agencies, as the case may be.

(x) “Submission Deadline” means 1:00 P.M., Eastern time, on any Auction Date or such other time on any Auction Date as may be specified by the Auction Agent from time to time as the time by which each Broker-Dealer must submit to the Auction Agent in writing all Orders obtained by it for the Auction to be conducted on such Auction Date.

(xii) “Submitted Hold Order” has the meaning specified in paragraph 10(d)(i) below.

(xiii) “Submitted Order” has the meaning specified in paragraph 10(d)(i) below.

(xiv) “Submitted Sell Order” has the meaning specified in paragraph 10(d)(i) below.

(xv) “Sufficient Clearing Bids” has the meaning specified in paragraph 10(d)(i) below.

(xvi) “Winning Bid Rate” has the meaning specified in paragraph 10(d)(i) below.

(b) Orders by Beneficial Owners, Potential Beneficial Owners, Existing Holders and Potential Holders. (i) Unless otherwise permitted by the Corporation, Beneficial Owners and Potential Beneficial Owners may only participate in Auctions through their Broker-Dealers. Broker-Dealers will submit the Orders of their respective customers who are Beneficial Owners and Potential Beneficial Owners to the Auction Agent, designating themselves as Existing Holders in respect of shares subject to Orders submitted or deemed submitted to them by Beneficial Owners and as Potential Holders in respect of shares subject to Orders submitted to them by Potential Beneficial Owners. A Broker-Dealer may also hold shares of AMPS in its own account as a Beneficial Owner. A Broker-Dealer may thus submit Orders to the Auction Agent as a Beneficial Owner or a Potential Beneficial Owner and therefore participate in an Auction as an Existing Holder or Potential Holder on behalf of both itself and its customers. On or prior to the Submission Deadline on each Auction Date:

(1) the number of Outstanding shares, if any, of AMPS held by such Beneficial Owner which such Beneficial Owner desires to continue to hold without regard to the Applicable Rate for the next succeeding Dividend Period;

(2) the number of Outstanding shares, if any, of AMPS held by such Beneficial Owner which such Beneficial Owner desires to continue to hold, provided that the Applicable Rate for the next succeeding Dividend Period shall not be less than the rate per annum specified by such Beneficial Owner; and/or

(3) the number of Outstanding shares, if any, of AMPS held by such Beneficial Owner which such Beneficial Owner offers to sell without regard to the Applicable Rate for the next succeeding Dividend Period; and

(B) each Broker-Dealer, using a list of Potential Beneficial Owners that shall be maintained in good faith for the purpose of conducting a competitive Auction, shall contact Potential Beneficial Owners, including Persons that are not Beneficial Owners, on such list to determine the number of Outstanding shares, if any, of AMPS which each such Potential Beneficial Owner offers to purchase, provided that the Applicable Rate for the next succeeding Dividend Period shall not be less than the rate per annum specified by such Potential Beneficial Owner.

For the purposes hereof, the communication by a Beneficial Owner or Potential Beneficial Owner to a Broker-Dealer, or the communication by a Broker-Dealer acting for its own account to the Auction Agent, of information referred to in clause (A) or (B) of this

paragraph 10(b)(i) is hereinafter referred to as an “Order” and each Beneficial Owner and each Potential Beneficial Owner placing an Order, including a Broker-Dealer acting in such capacity for its own account, is hereinafter referred to as a “Bidder”; an Order containing the information referred to in clause (A)(1) of this paragraph 10(b)(i) is hereinafter referred to as a “Hold Order”; an Order containing the information referred to in clause (A)(2) or (B) of this paragraph 10(b)(i) is hereinafter referred to as a “Bid”; and an Order containing the information referred to in clause (A)(3) of this paragraph 10(b)(i) is hereinafter referred to as a “Sell Order”. Inasmuch as a Broker-Dealer participates in an Auction as an Existing Holder or a Potential Holder only to represent the interests of a Beneficial Owner or Potential Beneficial Owner, whether it be its customers or itself, all discussion herein relating to the consequences of an Auction for Existing Holders and Potential Holders also applies to the underlying beneficial ownership interests represented.

(1) the number of Outstanding shares of AMPS specified in such Bid if the Applicable Rate determined on such Auction Date shall be less than the rate per annum specified in such Bid; or

(2) such number or a lesser number of Outstanding shares of AMPS to be determined as set forth in paragraph 10(e)(i)(D) if the Applicable Rate determined on such Auction Date shall be equal to the rate per annum specified therein; or

(3) a lesser number of Outstanding shares of AMPS to be determined as set forth in paragraph 10(e)(ii)(C) if such specified rate per annum shall be higher than the Maximum Applicable Rate and Sufficient Clearing Bids do not exist.

(B) A Sell Order by an Existing Holder shall constitute an irrevocable offer to sell:

(2) such number or a lesser number of Outstanding shares of AMPS to be determined as set forth in paragraph 10(e)(ii)(C) if Sufficient Clearing Bids do not exist.

(1) the number of Outstanding shares of AMPS specified in such Bid if the Applicable Rate determined on such Auction Date shall be higher than the rate per annum specified in such Bid; or

(2) such number or a lesser number of Outstanding shares of AMPS to be determined as set forth in paragraph 10(e)(i)(E) if the Applicable Rate determined on such Auction Date shall be equal to the rate per annum specified therein.

(i) Each Broker-Dealer shall submit in writing or through mutually acceptable electronic means to the Auction Agent prior to the Submission Deadline on each Auction Date all Orders obtained by such Broker-Dealer, designating itself (unless otherwise permitted by the Corporation) as an Existing Holder in respect of shares subject to Orders

submitted or deemed submitted to it by Beneficial Owners and as a Potential Holder in respect of shares subject to Orders submitted to it by Potential Beneficial Owners, and specifying with respect to each Order:

(A) the name of the Bidder placing such Order (which shall be the Broker-Dealer unless otherwise permitted by the Corporation);

(B) the aggregate number of Outstanding shares of AMPS that are the subject of such Order;

(1) the number of Outstanding shares, if any, of AMPS subject to any Hold Order placed by such Existing Holder;

(2) the number of Outstanding shares, if any, of AMPS subject to any Bid placed by such Existing Holder and the rate per annum specified in such Bid; and

(3) the number of Outstanding shares, if any, of AMPS subject to any Sell Order placed by such Existing Holder; and

(D) to the extent such Bidder is a Potential Holder, the rate per annum specified in such Potential Holder’s Bid.

(ii) If any rate per annum specified in any Bid contains more than three figures to the right of the decimal point, the Auction Agent shall round such rate up to the next highest one-thousandth (.001) of 1%.

(iii) If an Order or Orders covering all of the Outstanding shares of AMPS held by an Existing Holder are not submitted to the Auction Agent prior to the Submission Deadline, the Auction Agent shall deem a Hold Order (in the case of an Auction relating

to a Dividend Period which is not a Special Dividend Period of more than 28 days) and a Sell Order (in the case of an Auction relating to a Special Dividend Period of more than 28 days) to have been submitted on behalf of such Existing Holder covering the number of Outstanding shares of AMPS held by such Existing Holder and not subject to Orders submitted to the Auction Agent.

(iv) If one or more Orders on behalf of an Existing Holder covering in the aggregate more than the number of Outstanding shares of AMPS held by such Existing Holder are submitted to the Auction Agent, such Order shall be considered valid as follows and in the following order of priority:

(A) any Hold Order submitted on behalf of such Existing Holder shall be considered valid up to and including the number of Outstanding shares of AMPS held by such Existing Holder; provided that if more than one Hold Order is submitted on behalf of such Existing Holder and the number of shares of AMPS subject to such Hold Orders exceeds the number of Outstanding shares of AMPS held by such Existing Holder, the number of shares of AMPS subject to each of such Hold Orders shall be reduced pro rata so that such Hold Orders, in the aggregate, will cover exactly the number of Outstanding shares of AMPS held by such Existing Holder;

(B) any Bids submitted on behalf of such Existing Holder shall be considered valid, in the ascending order of their respective rates per annum if more than one Bid is submitted on behalf of such Existing Holder, up to and including the excess of the number of Outstanding shares of AMPS held by such Existing Holder over the number of shares of AMPS subject to any Hold Order

referred to in paragraph 10(c)(iv)(A) above (and if more than one Bid submitted on behalf of such Existing Holder specifies the same rate per annum and together they cover more than the remaining number of shares that can be the subject of valid Bids after application of paragraph 10(c)(iv)(A) above and of the foregoing portion of this paragraph 10(c)(iv)(B) to any Bid or Bids specifying a lower rate or rates per annum, the number of shares subject to each of such Bids shall be reduced pro rata so that such Bids, in the aggregate, cover exactly such remaining number of shares); and the number of shares, if any, subject to Bids not valid under this paragraph 10(c)(iv)(B) shall be treated as the subject of a Bid by a Potential Holder; and

(C) any Sell Order shall be considered valid up to and including the excess of the number of Outstanding shares of AMPS held by such Existing Holder over the number of shares of AMPS subject to Hold Orders referred to in paragraph 10(c)(iv)(A) and Bids referred to in paragraph 10(c)(iv)(B); provided that if more than one Sell Order is submitted on behalf of any Existing Holder and the number of shares of AMPS subject to such Sell Orders is greater than such excess, the number of shares of AMPS subject to each of such Sell Orders shall be reduced pro rata so that such Sell Orders, in the aggregate, cover exactly the number of shares of AMPS equal to such excess.

(v) If more than one Bid is submitted on behalf of any Potential Holder, each Bid submitted shall be a separate Bid with the rate per annum and number of shares of AMPS therein specified.

(vi) Any Order submitted by a Beneficial Owner as a Potential Beneficial Owner to its Broker-Dealer, or by a Broker-Dealer to the Auction Agent, prior to the Submission Deadline on any Auction Date shall be irrevocable.

(d) Determination of Sufficient Clearing Bids, Winning Bid Rate and Applicable Rate.

(i) Not earlier than the Submission Deadline on each Auction Date, the Auction Agent shall assemble all Orders submitted or deemed submitted to it by the Broker-Dealers (each such Order as submitted or deemed submitted by a Broker-Dealer being hereinafter referred to individually as a “Submitted Hold Order”, a “Submitted Bid” or a “Submitted Sell Order”, as the case may be, or as a “Submitted Order”) and shall determine:

(A) the excess of the total number of Outstanding shares of AMPS over the number of Outstanding shares of AMPS that are the subject of Submitted Hold Orders (such excess being hereinafter referred to as the “Available AMPS”);

(B) from the Submitted Orders whether the number of Outstanding shares of AMPS that are the subject of Submitted Bids by Potential Holders specifying one or more rates per annum equal to or lower than the Maximum Applicable Rate exceeds or is equal to the sum of:

(1) the number of Outstanding shares of AMPS that are the subject of Submitted Bids by Existing Holders specifying one or more rates per annum higher than the Maximum Applicable Rate, and

(2) the number of Outstanding shares of AMPS that are subject to Submitted Sell Orders (if such excess or such equality exists (other than because the number of Outstanding shares of AMPS in clause (1) above and this clause (2) are each zero because all of the Outstanding shares of

AMPS are the subject of Submitted Hold Orders), such Submitted Bids by Potential Holders being hereinafter referred to collectively as “Sufficient Clearing Bids”); and

(C) if Sufficient Clearing Bids exist, the lowest rate per annum specified in the Submitted Bids (the “Winning Bid Rate”) that if:

(1) each Submitted Bid from Existing Holders specifying the Winning Bid Rate and all other Submitted Bids from Existing Holders specifying lower rates per annum were rejected, thus entitling such Existing Holders to continue to hold the shares of AMPS that are the subject of such Submitted Bids, and

(2) each Submitted Bid from Potential Holders specifying the Winning Bid Rate and all other Submitted Bids from Potential Holders specifying lower rates per annum were accepted, thus entitling the Potential Holders to purchase the shares of AMPS that are the subject of such Submitted Bids,

would result in the number of shares subject to all Submitted Bids specifying the Winning Bid Rate or a lower rate per annum being at least equal to the Available AMPS.

(ii) Promptly after the Auction Agent has made the determinations pursuant to paragraph 10(d)(i), the Auction Agent shall advise the Corporation of the Maximum Applicable Rate and, based on such determinations, the Applicable Rate for the next succeeding Dividend Period as follows:

(A) if Sufficient Clearing Bids exist, that the Applicable Rate for the next succeeding Dividend Period shall be equal to the Winning Bid Rate;

(B) if Sufficient Clearing Bids do not exist (other than because all of the Outstanding shares of AMPS are the subject of Submitted Hold Orders), that the Applicable Rate for the next succeeding Dividend Period shall be equal to the Maximum Applicable Rate; or

(C) if all of the Outstanding shares of AMPS are the subject of Submitted Hold Orders, the Dividend Period next succeeding the Auction shall automatically be the same length as the immediately preceding Dividend Period and the Applicable Rate for the next succeeding Dividend Period shall be equal to 60% of the Reference Rate (or 90% of such rate if the Corporation has provided notification to the Auction Agent prior to the Auction establishing the Applicable Rate for any dividend pursuant to paragraph 2(f) hereof that net capital gains or other taxable income will be included in such dividend on shares of AMPS) on the date of the Auction.

(e) Acceptance and Rejection of Submitted Bids and Submitted Sell Orders and Allocation of Shares.

Based on the determinations made pursuant to paragraph 10(d)(i), the Submitted Bids and Submitted Sell Orders shall be accepted or rejected and the Auction Agent shall take such other action as set forth below:

(i) If Sufficient Clearing Bids have been made, subject to the provisions of paragraph 10(e)(iii) and paragraph 10(e)(iv), Submitted Bids and Submitted Sell Orders shall be accepted or rejected in the following order of priority and all other Submitted Bids shall be rejected:

(A) the Submitted Sell Orders of Existing Holders shall be accepted and the Submitted Bid of each of the Existing Holders specifying any rate per annum that is higher than the Winning Bid Rate shall be accepted, thus requiring each such Existing Holder to sell the Outstanding shares of AMPS that are the subject of such Submitted Sell Order or Submitted Bid;

(B) the Submitted Bid of each of the Existing Holders specifying any rate per annum that is lower than the Winning Bid Rate shall be rejected, thus entitling each such Existing Holder to continue to hold the Outstanding shares of AMPS that are the subject of such Submitted Bid;

(C) the Submitted Bid of each of the Potential Holders specifying any rate per annum that is lower than the Winning Bid Rate shall be accepted;

(D) the Submitted Bid of each of the Existing Holders specifying a rate per annum that is equal to the Winning Bid Rate shall be rejected, thus entitling each such Existing Holder to continue to hold the Outstanding shares of AMPS that are the subject of such Submitted Bid, unless the number of Outstanding shares of AMPS subject to all such Submitted Bids shall be greater than the number of Outstanding shares of AMPS (“Remaining Shares”) equal to the excess of the Available AMPS over the number of Outstanding shares of AMPS subject to Submitted Bids described in paragraph 10(e)(i)(B) and paragraph 10(e)(i)(C), in which event the Submitted Bids of each such Existing Holder shall be accepted, and each such Existing Holder shall be required to sell Outstanding shares of AMPS, but only in an amount equal to the difference between (1) the number of Outstanding shares of AMPS then held by such Existing Holder subject to such

Submitted Bid and (2) the number of shares of AMPS obtained by multiplying (x) the number of Remaining Shares by (y) a fraction the numerator of which shall be the number of Outstanding shares of AMPS held by such Existing Holder subject to such Submitted Bid and the denominator of which shall be the sum of the number of Outstanding shares of AMPS subject to such Submitted Bids made by all such Existing Holders that specified a rate per annum equal to the Winning Bid Rate; and

(E) the Submitted Bid of each of the Potential Holders specifying a rate per annum that is equal to the Winning Bid Rate shall be accepted but only in an amount equal to the number of Outstanding shares of AMPS obtained by multiplying (x) the difference between the Available AMPS and the number of Outstanding shares of AMPS subject to Submitted Bids described in paragraph 10(e)(i)(B), paragraph 10(e)(i)(C) and paragraph 10(e)(i)(D) by (y) a fraction the numerator of which shall be the number of Outstanding shares of AMPS subject to such Submitted Bid and the denominator of which shall be the sum of the number of Outstanding shares of AMPS subject to such Submitted Bids made by all such Potential Holders that specified rates per annum equal to the Winning Bid Rate.

(ii) If Sufficient Clearing Bids have not been made (other than because all of the Outstanding shares of AMPS are subject to Submitted Hold Orders), subject to the provisions of paragraph 10(e)(iii), Submitted Orders shall be accepted or rejected as follows in the following order of priority and all other Submitted Bids shall be rejected:

(A) the Submitted Bid of each Existing Holder specifying any rate per annum that is equal to or lower than the Maximum Applicable Rate shall be rejected, thus entitling such Existing Holder to continue to hold the Outstanding shares of AMPS that are the subject of such Submitted Bid;

(B) the Submitted Bid of each Potential Holder specifying any rate per annum that is equal to or lower than the Maximum Applicable Rate shall be accepted, thus requiring such Potential Holder to purchase the Outstanding shares of AMPS that are the subject of such Submitted Bid; and

(C) the Submitted Bids of each Existing Holder specifying any rate per annum that is higher than the Maximum Applicable Rate shall be accepted and the Submitted Sell Orders of each Existing Holder shall be accepted, in both cases only in an amount equal to the difference between (1) the number of Outstanding shares of AMPS then held by such Existing Holder subject to such Submitted Bid or Submitted Sell Order and (2) the number of shares of AMPS obtained by multiplying (x) the difference between the Available AMPS and the aggregate number of Outstanding shares of AMPS subject to Submitted Bids described in paragraph 10(e)(ii)(A) and paragraph 10(e)(ii)(B) by (y) a fraction the numerator of which shall be the number of Outstanding shares of AMPS held by such Existing Holder subject to such Submitted Bid or Submitted Sell Order and the denominator of which shall be the number of Outstanding shares of AMPS subject to all such Submitted Bids and Submitted Sell Orders.

(iii) If, as a result of the procedures described in paragraph 10(e)(i) or paragraph 10(e)(ii), any Existing Holder would be entitled or required to sell, or any Potential

Holder would be entitled or required to purchase, a fraction of a share of AMPS on any Auction Date, the Auction Agent shall, in such manner as in its sole discretion it shall determine, round up or down the number of shares of AMPS to be purchased or sold by any Existing Holder or Potential Holder on such Auction Date so that each Outstanding share of AMPS purchased or sold by each Existing Holder or Potential Holder on such Auction Date shall be a whole share of AMPS.

(iv) If, as a result of the procedures described in paragraph 10(e)(i), any Potential Holder would be entitled or required to purchase less than a whole share of AMPS on any Auction Date, the Auction Agent shall, in such manner as in its sole discretion it shall determine, allocate shares of AMPS for purchase among Potential Holders so that only whole shares of AMPS are purchased on such Auction Date by any Potential Holder, even if such allocation results in one or more of such Potential Holders not purchasing any shares of AMPS on such Auction Date.

(v) Based on the results of each Auction, the Auction Agent shall determine, with respect to each Broker-Dealer that submitted Bids or Sell Orders on behalf of Existing Holders or Potential Holders, the aggregate number of Outstanding shares of AMPS to be purchased and the aggregate number of the Outstanding shares of AMPS to be sold by such Potential Holders and Existing Holders and, to the extent that such aggregate number of Outstanding shares to be purchased and such aggregate number of Outstanding shares to be sold differ, the Auction Agent shall determine to which other Broker-Dealer or Broker-Dealers acting for one or more purchasers such Broker-Dealer shall deliver, or from which other Broker-Dealer or Broker-Dealers acting for one or more sellers such Broker-Dealer shall receive, as the case may be, Outstanding shares of AMPS.

(f) Miscellaneous. The Corporation may interpret the provisions of this paragraph 10 to resolve any inconsistency or ambiguity, remedy any formal defect or make any other change or modification that does not substantially adversely affect the rights of Beneficial Owners of AMPS. A Beneficial Owner or an Existing Holder (A) may sell, transfer or otherwise dispose of shares of AMPS only pursuant to a Bid or Sell Order in accordance with the procedures described in this paragraph 10 or to or through a Broker-Dealer, provided that in the case of all transfers other than pursuant to Auctions such Beneficial Owner or Existing Holder, its Broker-Dealer, if applicable, or its Agent Member advises the Auction Agent of such transfer and (B) except as otherwise required by law, shall have the ownership of the shares of AMPS held by it maintained in book entry form by the Securities Depository in the account of its Agent Member, which in turn will maintain records of such Beneficial Owner’s beneficial ownership. Neither the Corporation nor any Affiliate, other than an Affiliate that is a Broker-Dealer, shall submit an Order in any Auction. Any Beneficial Owner that is an Affiliate shall not sell, transfer or otherwise dispose of shares of AMPS to any Person other than the Corporation. All of the Outstanding shares of AMPS shall be represented by a single certificate registered in the name of the nominee of the Securities Depository unless otherwise required by law or unless there is no Securities Depository. If there is no Securities Depository, at the Corporation’s option and upon its receipt of such documents as it deems appropriate, any shares of AMPS may be registered in the Stock Register in the name of the Beneficial Owner thereof and such Beneficial Owner thereupon will be entitled to receive certificates therefor and required to deliver certificates therefor upon transfer or exchange thereof.

(a) If there is a Securities Depository, one certificate for all of the shares of AMPS shall be issued to the Securities Depository and registered in the name of the Securities Depository or its nominee. Additional certificates may be issued as necessary to represent shares of AMPS. All such certificates shall bear a legend to the effect that such certificates are issued subject to the provisions restricting the transfer of shares of AMPS contained in these Articles Supplementary. Unless the Corporation shall have elected, during a Non-Payment Period, to waive this requirement, the Corporation will also issue stop-transfer instructions to the Auction Agent for the shares of AMPS. Except as provided in paragraph (b) below, the Securities Depository or its nominee will be the Holder, and no Beneficial Owner shall receive certificates representing its ownership interest in such shares.
