FIRST: Under a power contained in Article VII of the charter of the Company (the “Charter”) and Section 2-105 of the Maryland General Corporation Law, the Board of Directors of the Company (the “Board”) and a duly authorized committee thereof, by duly adopted resolutions, reclassified 1,700,000 shares of authorized but unissued common stock, par value $0.001 per share, of the Company as shares of 7.125% Series C Cumulative Term Preferred Stock, with the following preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends and other distributions, qualifications, and terms and conditions of redemption (which, upon any restatement of the Charter, may be made a part of Article VII thereof, with any necessary or appropriate changes to the numeration or lettering of the sections or subsections hereof):

1. Designation and Number. A series of preferred stock, designated the 7.125% Series C Cumulative Term Preferred Stock (the “Series C Term Preferred Stock”), is hereby established. The number of shares of Series C Term Preferred Stock shall be 1,700,000.

2. Rank. The Series C Term Preferred Stock, with respect to dividend rights and rights upon liquidation, dissolution or winding up of the Company, will rank (i) senior to all classes or series of senior common stock, par value $0.001 per share, and common stock, par value $0.001 per share, of the Company (collectively, the “Common Stock”) and to all other equity securities issued by the Company the terms of which specifically provide that such equity securities rank junior to the Series C Term Preferred Stock with respect to dividend rights or rights upon liquidation, dissolution or winding up of the Company; (ii) on a parity with all equity securities issued by the Company the terms of which specifically provide that such equity securities rank on a parity with the Series C Term Preferred Stock with respect to dividend rights and rights upon liquidation, dissolution or winding up of the Company, including, but not limited to, each of the 7.75% Series A Perpetual Cumulative Redeemable Preferred Stock, par value $0.001 per share, and 7.50% Series B Perpetual Cumulative Redeemable Preferred Stock, par value $0.001 per share, of the Company (collectively, the “Parity Preferred Stock”); and (iii) junior to all equity securities issued by the Company the terms of which specifically provide that such equity securities rank senior to the Series C Term Preferred Stock with respect to dividend rights or rights upon liquidation, dissolution or winding up of the Company and to all existing and future indebtedness of the Company.

3. Dividends.

(a) Holders of shares of the Series C Term Preferred Stock are entitled to receive, when and as authorized by the Board (or a duly authorized committee thereof) and declared by the Company, out of funds legally available for the payment of dividends, preferential cumulative cash dividends at the rate of 7.125% per annum of the $25.00 liquidation preference per share (equivalent to a fixed annual amount of $1.7813 per share). Dividends on the Series C Term Preferred Stock shall be cumulative from (but excluding) the date of original issue and shall be payable monthly in arrears on or before the last Business Day (as defined below) of each month (each, a “Dividend Payment Date”). Any dividend payable on the Series C Term Preferred Stock for any partial dividend period will be computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends will be payable to holders of record as they appear in the stock records of the Company at the close of business on the applicable record date, which shall be such date designated by the Board that is not more than 20 nor less than seven days prior to the applicable Dividend Payment Date (each, a “Dividend Record Date”). The term “Business Day” shall mean any calendar day on which the New York Stock Exchange is open for trading.

(b) No dividends on shares of Series C Term Preferred Stock shall be authorized by the Board of Directors or declared by the Company or paid or set apart for payment by the Company at such time as the terms and provisions of any agreement of the Company, including any agreement relating to its indebtedness, prohibits such authorization, declaration, payment or setting apart for payment or provides that such authorization, declaration, payment or setting apart for payment would constitute a breach thereof or a default thereunder, or if such authorization, declaration, payment or setting apart for payment shall be restricted or prohibited by law.

(c) Notwithstanding the foregoing, dividends on the Series C Term Preferred Stock will accumulate whether or not the Company has earnings, whether or not restrictions exist in respect thereof, whether there are funds legally available for the payment of such dividends and whether or not such dividends are declared. Accumulated but unpaid dividends on the Series C Term Preferred Stock will not bear interest and holders of the Series C Term Preferred Stock will not be entitled to any distributions in excess of full cumulative distributions described above. When dividends are not paid in full (or a sum sufficient for such full payment is not so set apart) upon the Series C Term Preferred Stock and the shares of any class or series of Parity Preferred Stock, all dividends declared upon the Series C Term Preferred Stock and any class or series of Parity Preferred Stock shall be declared pro rata so that the amount of dividends

- 2 -

declared per share of Series C Term Preferred Stock and such class or series of Parity Preferred Stock shall in all cases bear to each other the same ratio that accumulated dividends per share on the Series C Term Preferred Stock and such class or series of Parity Preferred Stock (which shall not include any accrual in respect of unpaid dividends for prior dividend periods if such Parity Preferred Stock does not have a cumulative dividend) bear to each other.

(d) Except as provided in the immediately preceding paragraph, unless full cumulative dividends on the Series C Term Preferred Stock have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof is set apart for payment for all past dividend periods, no dividends (other than a dividend in shares of Common Stock or other shares of stock ranking junior to the Series C Term Preferred Stock as to dividends and upon liquidation) shall be declared and paid or declared and set apart for payment nor shall any other distribution be declared and made upon the Common Stock or any other stock of the Company ranking junior to or on a parity with the Series C Term Preferred Stock as to dividends or upon liquidation, nor shall any shares of Common Stock or any other stock of the Company ranking junior to or on a parity with the Series C Term Preferred Stock as to dividends or upon liquidation be redeemed, purchased or otherwise acquired for any consideration (or any monies be paid to or made available for a sinking fund for the redemption of any such shares) by the Company (except by conversion into or exchange for other stock of the Company ranking junior to the Series C Term Preferred Stock as to dividends and upon liquidation or redemption for the purpose of preserving the Company’s qualification as a real estate investment trust (“REIT”)). Holders of shares of the Series C Term Preferred Stock shall not be entitled to any dividend, whether payable in cash, property or stock, in excess of full cumulative dividends on the Series C Term Preferred Stock as provided above. Any dividend payment made on shares of the Series C Term Preferred Stock shall first be credited against the earliest accumulated but unpaid dividend due with respect to such shares which remains payable.

(e) If, for any taxable year, the Company elects to designate as a “capital gain dividend” (as defined in Section 857 of the Internal Revenue Code of 1986, as amended (the “Code”)) any portion (the “Capital Gains Amount”) of the dividends paid or made available for the year to holders of any class or series of stock of the Company, the portion of the Capital Gains Amount that shall be allocable to holders of the Series C Term Preferred Stock shall be the amount that the total dividends (as determined for federal income tax purposes) paid or made available to the holders of the Series C Term Preferred Stock for the year bears to the aggregate amount of dividends (as determined for federal income tax purposes) paid or made available to the holders of all classes or series of stock of the Company for such year.

4. Liquidation Preference. Upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, the holders of shares of Series C Term Preferred Stock are entitled to be paid out of the assets of the Company legally available for distribution to its stockholders a liquidation preference of $25.00 per share, plus an amount equal to any accumulated and unpaid dividends to and including the date of payment, but without interest, before any distribution of assets is made to holders of Common Stock or any other class or series of stock of the Company that ranks junior to the Series C Term Preferred Stock as to liquidation rights. If the assets of the Company legally available for distribution to stockholders are insufficient to pay in full the liquidation preference on the Series C Term Preferred Stock and the liquidation preference on the shares of any class or series of Parity Preferred Stock, all assets distributed to the holders of the Series C Term Preferred Stock and any class or series of Parity Preferred Stock shall be distributed pro rata so that the amount of assets distributed per share of Series C Term Preferred Stock and such class or series of Parity Preferred Stock shall in all cases bear to each other the same ratio that the liquidation preference per share on the Series C Term Preferred Stock and such class or series of Parity Preferred Stock bear to each other. Written notice of any such liquidation, dissolution or winding up of the Company, stating the payment date or dates when, and the place or places where, the amounts distributable in such circumstances shall be payable, shall be given by first class mail, postage pre-paid, not less than 30 nor more than 60 days prior to the payment date stated therein, to each record holder of the Series C Term Preferred Stock at the respective addresses of such holders as the same shall appear on the stock transfer records of the Company. After payment of the full amount of the liquidation preference, plus any accumulated and unpaid dividends to which they are entitled, the holders of Series C Term Preferred Stock will have no right or claim to any of the remaining assets of the Company. The consolidation or merger of the Company with or into another entity, a merger of another entity with or into the Company, a statutory share exchange by the Company or a sale, lease, transfer or conveyance of all or substantially all of the Company’s property or business shall not be deemed to constitute a liquidation, dissolution or winding up of the Company. In determining whether a distribution (other than upon voluntary or involuntary liquidation, dissolution or winding up of the Company) by dividend, redemption or other acquisition of shares of stock of the Company or otherwise is permitted under the Maryland General Corporation Law, no effect shall be given to amounts that would be needed, if the Company were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of holders of the Series C Term Preferred Stock whose preferential rights upon dissolution are superior to those receiving the distribution.

- 10 -

Redemption Price on a per share basis; (E) if applicable, the place or places where the certificate(s) for such shares (properly endorsed or assigned for transfer, if the Board of Directors requires and the Notice of Redemption states) are to be surrendered for payment of the Redemption Price; (F) that dividends on the shares of Series C Term Preferred Stock to be redeemed will cease to accumulate after such Redemption Date; and (G) the provisions hereof under which such redemption is made. If fewer than all shares of Series C Term Preferred Stock held by any holder are to be redeemed, the Notice of Redemption delivered to such holder shall also specify the number of shares of Series C Term Preferred Stock to be redeemed from such holder or the method of determining such number. The Company may provide in any Notice of Redemption relating to a redemption contemplated to be effected pursuant hereto that such redemption is subject to one or more conditions precedent and that the Company shall not be required to effect such redemption unless each such condition has been satisfied at the time or times and in the manner specified in such Notice of Redemption. No defect in the Notice of Redemption or delivery thereof shall affect the validity of redemption proceedings, except as required by applicable law.

(ii) If the Company shall give a Notice of Redemption, then at any time from and after the giving of such Notice of Redemption and prior to 12:00 noon, New York City time, on the Redemption Date (so long as any conditions precedent to such redemption have been met or waived by the Company), the Company shall (A) deposit with the Redemption and Paying Agent Deposit Securities having an aggregate Market Value on the date thereof no less than the Redemption Price of the shares of Series C Term Preferred Stock to be redeemed on the Redemption Date and (B) give the Redemption and Paying Agent irrevocable instructions and authority to pay the applicable Redemption Price to the holders of the shares of Series C Term Preferred Stock called for redemption on the Redemption Date. The Company may direct the Redemption and Paying Agent with respect to the investment of any Deposit Securities consisting of cash so deposited prior to the Redemption Date, provided that the proceeds of any such investment shall be available at the opening of business on the Redemption Date as same day funds.

(iii) Upon the date of the deposit of such Deposit Securities, all rights of the holders of the shares of Series C Term Preferred Stock so called for redemption shall cease and terminate except the right of the holders thereof to receive the Redemption Price thereof and such shares of Series C Term Preferred Stock shall no longer be deemed outstanding for any purpose whatsoever (other than (A) the transfer thereof prior to the applicable Redemption Date and (B) the accumulation of dividends thereon in accordance with the terms hereof up to (but excluding) the applicable Redemption Date, which accumulated dividends, unless previously or contemporaneously declared and paid as contemplated by the last sentence of Section 5(e)(vi) below, shall be payable only as part of the applicable Redemption Price on the Redemption Date). The Company shall be entitled to receive, promptly after the Redemption Date, any

- 11 -

Deposit Securities in excess of the aggregate Redemption Price of the shares of Series C Term Preferred Stock called for redemption on the Redemption Date. Any Deposit Securities so deposited that are unclaimed at the end of 90 calendar days from the Redemption Date shall, to the extent permitted by law, be repaid to the Company, after which the holders of the shares of Series C Term Preferred Stock so called for redemption shall look only to the Company for payment of the Redemption Price thereof. The Company shall be entitled to receive, from time to time after the Redemption Date, any interest on the Deposit Securities so deposited.

(iv) On or after the Redemption Date, each holder of shares of Series C Term Preferred Stock in certificated form (if any) that are subject to redemption shall surrender the certificate(s) representing such shares of Series C Term Preferred Stock to the Company at the place designated in the Notice of Redemption and shall then be entitled to receive the Redemption Price for such shares of Series C Term Preferred Stock, without interest, and in the case of a redemption of fewer than all the shares of Series C Term Preferred Stock represented by such certificate(s), a new certificate representing the shares of Series C Term Preferred Stock that were not redeemed.

(v) Notwithstanding the other provisions of this Section 5, except as otherwise required by law, the Company shall not redeem any shares of Series C Term Preferred Stock unless all accumulated and unpaid dividends on all outstanding shares of Series C Term Preferred Stock and the shares of any class or series of Parity Preferred Stock for all applicable past dividend periods (whether or not earned or declared by the Company) (x) shall have been or are contemporaneously paid or (y) shall have been or are contemporaneously declared and Deposit Securities or sufficient funds (in accordance with the terms of such Parity Preferred Stock) for the payment of such dividends shall have been or are contemporaneously deposited with the Redemption and Paying Agent or other applicable paying agent for such Parity Preferred Stock in accordance with the terms of such Parity Preferred Stock, provided, however, that the foregoing shall not prevent the purchase or acquisition of outstanding shares of Series C Term Preferred Stock pursuant to an otherwise lawful purchase or exchange offer made on the same terms to holders of all outstanding shares of Series C Term Preferred Stock and any other class or series of Parity Preferred Stock for which all accumulated and unpaid dividends have not been paid.

(vi) To the extent that any redemption for which Notice of Redemption has been provided is not made by reason of the absence of legally available funds therefor in accordance herewith and applicable law, such redemption shall be made as soon as practicable to the extent such funds become available. No Redemption Default shall be deemed to have occurred if the Company shall fail to deposit in trust with the Redemption and Paying Agent the Redemption Price with respect to any shares where (1) the Notice of Redemption relating to such redemption provided that such redemption was subject to one or more conditions precedent and

- 12 -

(2) any such condition precedent shall not have been satisfied at the time or times and in the manner specified in such Notice of Redemption. Notwithstanding the fact that a Notice of Redemption has been provided with respect to any shares of Series C Term Preferred Stock, dividends may be declared and paid on such shares of Series C Term Preferred Stock in accordance with their terms if Deposit Securities for the payment of the Redemption Price of such shares of Series C Term Preferred Stock shall not have been deposited in trust with the Redemption and Paying Agent for that purpose.

(f) Redemption and Paying Agent as Trustee of Redemption Payments by Company. All Deposit Securities transferred to the Redemption and Paying Agent for payment of the Redemption Price of shares of Series C Term Preferred Stock called for redemption shall be held in trust by the Redemption and Paying Agent for the benefit of holders of shares of Series C Term Preferred Stock so to be redeemed until paid to such holders in accordance with the terms hereof or returned to the Company in accordance with the provisions of Section 5(e)(iii) above.

(g) Compliance With Applicable Law. In effecting any redemption pursuant to this Section 5, the Company shall use its best efforts to comply with all applicable conditions precedent to effecting such redemption under any applicable Maryland law, but shall effect no redemption except in accordance with any applicable Maryland law.

(h) Modification of Redemption Procedures. Notwithstanding the foregoing provisions of this Section 5, the Company may, in its sole discretion and without a stockholder vote, modify the procedures set forth above with respect to notification of redemption for the Series C Term Preferred Stock; provided that such modification does not materially and adversely affect the holders of the shares of Series C Term Preferred Stock or cause the Company to violate any applicable law, rule or regulation; and provided, further, that no such modification shall in any way alter the rights or obligations of the Redemption and Paying Agent without its prior consent.

6. Voting Rights.

(a) Holders of the Series C Term Preferred Stock will not have any voting rights, except as set forth below.

(b) Whenever dividends on any shares of Series C Term Preferred Stock shall be in arrears for 18 or more consecutive months (a “Preferred Dividend Default”), the holders of such shares of Series C Term Preferred Stock, together with the holders of all classes or series of Parity Preferred Stock upon which like voting rights have been conferred and are exercisable, will be entitled to vote separately as a class for the election of a total of two additional directors

of the Company (the “Dividend Default Preferred Stock Directors”) at a special meeting called upon the request of the holders of record of at least 20% of the Series C Term Preferred Stock or the holders of record of at least 20% of any class or series of Parity Preferred Stock so in arrears (unless such request is received less than 90 days before the date fixed for the next annual or special meeting of the stockholders) or at the next annual meeting of stockholders, and at each subsequent annual meeting until all dividends accumulated on such shares of Series C Term Preferred Stock for the past dividend periods and the dividend for the then current dividend period shall have been fully paid or declared and a sum sufficient for the payment thereof set apart for payment.

(c) Whenever shares of the Series C Term Preferred Stock are not redeemed or are not called for redemption with proper notice and a sum sufficient for the payment thereof set apart for payment as required on January 31, 2017 (a “Mandatory Redemption Delay”), the number of directors constituting the Board shall be automatically increased by the smallest number that would constitute a majority of the Board as so increased by such smallest number, and the holders of such shares of Series C Term Preferred Stock will be entitled, voting as a separate class (to the exclusion of the holders of all other classes or series of stock of the Company), to elect such number of additional directors (the “Redemption Delay Preferred Stock Directors” and, together with the Dividend Default Preferred Stock Directors, the “Preferred Stock Directors”) at a special meeting called upon the request of the holders of record of at least 20% of the Series C Term Preferred Stock (unless such request is received less than 90 days before the date fixed for the next annual or special meeting of the stockholders) or at the next annual meeting of stockholders, and at each subsequent annual meeting until all shares of Series C Term Preferred Stock are redeemed or called for redemption upon proper notice and a sum sufficient for the payment thereof set apart for payment.

(d) A quorum for any meeting called to elect Preferred Stock Directors shall exist if at least a majority of the outstanding shares of Series C Term Preferred Stock and, in the case of a Preferred Dividend Default, shares of Parity Preferred Stock upon which like voting rights have been conferred and are exercisable are represented in person or by proxy at such meeting. The Preferred Stock Directors shall be elected upon the affirmative vote of a plurality of the votes cast by the holders of shares of Series C Term Preferred Stock and, in the case of a Preferred Dividend Default, shares of such Parity Preferred Stock present and voting in person or by proxy at a duly called and held meeting at which a quorum is present voting separately as a class. If and when all accumulated dividends and the dividend for the then-current dividend period on the Series C Term Preferred Stock shall have been paid in full or declared and set apart for payment in full, the holders thereof shall be divested of the right to elect the Dividend Default Preferred Stock Directors (subject to revesting in the event of each and every Preferred Dividend Default) and, if all accumulated dividends and the dividend for the then-current dividend period have been paid in full or declared and set aside for payment in full on all classes or series of

Parity Preferred Stock upon which like voting rights have been conferred and are exercisable, the term of office of each Dividend Default Preferred Stock Director so elected shall terminate; and if and when all shares of Series C Term Preferred Stock are redeemed or called for redemption upon proper notice and a sum sufficient for the payment thereof set apart for payment, the holders thereof shall be divested of the right to elect the Redemption Delay Preferred Stock Directors and the term of office of each Redemption Delay Preferred Stock Director so elected shall terminate. Any Preferred Stock Director may be removed at any time with or without cause by, and shall not be removed otherwise than by the vote of, the holders of record of a majority of the outstanding shares of Series C Term Preferred Stock when they have the voting rights described above (voting separately as a class, in the case of a Preferred Dividend Default, with all classes or series of Parity Preferred Stock upon which like voting rights have been conferred and are exercisable or, in the case of a Mandatory Redemption Delay, to the exclusion of the holders of all other classes or series of stock of the Company). So long as a Preferred Dividend Default or Mandatory Redemption Delay shall continue, any vacancy in the office of a Preferred Stock Director may be filled by written consent of the Dividend Default Preferred Stock Director or Redemption Delay Preferred Stock Director(s), as the case may be, remaining in office or, if none remains in office, by a vote of the holders of record of a majority of the outstanding shares of Series C Term Preferred Stock when they have the voting rights described above (voting separately as a class, in the case of a Preferred Dividend Default, with all classes or series of Parity Preferred Stock upon which like voting rights have been conferred and are exercisable or, in the case of a Mandatory Redemption Delay, to the exclusion of the holders of all other classes or series of stock of the Company). The Preferred Stock Directors shall be entitled to one vote per director on any matter.

(e) So long as any shares of Series C Term Preferred Stock remain outstanding, the Company will not, without the affirmative vote or consent of the holders of at least two-thirds of the shares of the Series C Term Preferred Stock outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting separately as a class), amend, alter or repeal the provisions of the Charter (including terms of the Series C Term Preferred Stock), whether by merger, consolidation or otherwise (each an “Event”), so as to materially and adversely affect any right, preference, privilege or voting power of the Series C Term Preferred Stock; provided, however, that with respect to the occurrence of any Event set forth above, so long as the Series C Term Preferred Stock (or securities issued by a surviving entity in substitution for the Series C Term Preferred Stock) remains outstanding with the terms thereof materially unchanged, taking into account that upon the occurrence of such an Event, the Company may not be the surviving entity, the occurrence of any such Event shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting power of the Series C Term Preferred Stock; and provided, further, that (i) any increase in the number of authorized shares of Series C Term Preferred Stock, (ii) any increase in the number of authorized shares of preferred stock of the Company or the creation of issuance of any other class or series

of preferred stock, or (iii) any increase in the number of authorized shares of any other class or series of preferred stock, in each case ranking on a parity with or junior to the Series C Term Preferred Stock with respect to payment of dividends or the distribution of assets upon liquidation, dissolution or winding up, shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting powers.

(f) The foregoing voting provisions will not apply if, at or prior to the time when the act with respect to which such vote would otherwise be required shall be effected, all outstanding shares of Series C Term Preferred Stock shall have been redeemed or called for redemption upon proper notice and sufficient funds shall have been deposited in trust to effect such redemption.
