ARTICLE 29.

SERIES J PREFERRED UNITS

Section 29.1    Definitions. The term “Series J Parity Preferred Units” shall mean any class or series of OP Units of the Partnership now or hereafter authorized, issued or outstanding and expressly designated by the Partnership to rank on parity with the Series J Preferred Units with respect to distributions and rights upon voluntary or involuntary liquidation, winding-up or dissolution of the Partnership. The term “Series J Priority Return” shall mean an amount equal to the Series J Applicable Rate multiplied by the stated issue price of $100.00 (the “Series J Issue Price”) per Series J Preferred Unit per annum. The term “Series J Applicable Rate” shall mean: 2.85% per annum (determined on the basis of a 365 day year).

Section 29.2    Designation and Number. A series of OP Units in the Partnership designated as the Series J Preferred Units (the “Series J Preferred Units”) is hereby established. The number of Series J Preferred Units shall be 240,000.

Section 29.3     Distributions.

(a) Payment of Distributions.

(i)Subject to the preferential rights of holders of any class or series of OP Units of the Partnership ranking senior to the Series J Preferred Units, the holders of Series J Preferred Units will be entitled to receive, when, as and if declared by the

5

Partnership acting through the General Partner, out of the Partnership’s available cash, cumulative preferential cash distributions in an amount equal to the Series J Priority Return.

(ii)All distributions shall be cumulative, shall accrue from the date of issuance, and will be payable quarterly (such quarterly periods for purposes of payment and accrual will be the quarterly periods ending on the dates specified in this sentence) in arrears on March 31, June 30, September 30 and December 31 of each year (each a “Series J Preferred Unit Distribution Payment Date”), and will be computed on the basis of a 365-day year. If any Series J Preferred Unit Distribution Payment Date is not a Business Day, then payment of the distribution to be made on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay). The distributions payable on any Series J Preferred Unit Distribution Payment Date shall include distributions accrued to but not including such Series J Preferred Unit Distribution Payment Date. Distributions payable on any Series J Preferred Units shall be pro-rated for the quarter in which the Series J Preferred Units are first issued.

(b)Distributions Cumulative. Notwithstanding the foregoing, distributions on the Series J Preferred Units will accrue and be cumulative from the Series J Issuance Date, whether or not the terms and provisions set forth in the last sentence of this Section 29.3(b) at any time prohibit the declaration, setting aside for payment or current payment of distributions, whether or not the Partnership has earnings, whether or not there are funds legally available for the payment of such distributions and whether or not such distributions are authorized. No interest, or sum in lieu of interest, will be payable in respect of any distribution payment or payments on Series J Preferred Units which may be in arrears, and the holders of the Series J Preferred Units will not be entitled to any distributions, whether payable in cash, securities or other property, in excess of full cumulative distributions described above. Any distribution payment made on the Series J Preferred Units will first be credited against the earliest accrued but unpaid distribution due with respect to the Series J Preferred Units. No distributions on the Series J Preferred Units shall be authorized, declared, paid or set apart for payment by the Partnership at such time as the terms and provisions of any agreement of the Partnership, including any agreement relating to its indebtedness, directly or indirectly prohibit authorization, declaration, payment or setting apart for payment or provide that such authorization, declaration, payment or setting apart for payment would constitute a breach thereof or a default thereunder, or if such declaration, payment or setting apart for payment shall be restricted or prohibited by law.

(c)Priority as to Distributions.

(i)Except as provided in Section 29.3(c)(ii) below, unless full cumulative distributions for all past Series J Preferred Unit Distribution Periods on the Series J Preferred Units have been or contemporaneously are authorized and paid or authorized and a sum sufficient for the payment thereof is set apart for such payment, no distributions (other than in Common OP Units or any other class or series of OP Units ranking junior to the Series J Preferred Units as to distributions and as to the distribution of assets upon liquidation, dissolution and winding up of the Partnership) shall be authorized or paid or set aside for payment nor shall any other distribution be authorized or made on Common OP Units or any other classes or series of OP Units ranking junior to or on parity with the Series J Preferred Units as to distributions or as to the distribution

6

of assets upon liquidation, dissolution or winding up of the Partnership nor shall any Common OP Units or any other classes or series of OP Units ranking junior to or on parity with the Series J Preferred Units as to distributions or as to the distribution of assets upon liquidation, dissolution or winding up of the Partnership be redeemed, purchased or otherwise acquired for any consideration (or any amounts be paid to or made available for a sinking fund for the redemption of any such units) by the Partnership except: (1) by conversion into or exchange for Common OP Units or any other classes or series of OP Units ranking junior to the Series J Preferred Units as to distributions and as to the distribution of assets upon liquidation, dissolution and winding up of the Partnership, (2) by redemption, purchase or other acquisition of Common OP Units made for purposes of an incentive, benefit or share purchase plan for the General Partner, the Partnership or any of their respective subsidiaries, (3) for redemptions, purchases or other acquisitions of OP Units by the Partnership in connection with the General Partner’s purchase of its securities for the purpose of preserving the General Partner’s qualification as a REIT for federal income tax purposes, or (4) for any distributions by the Partnership corresponding to distributions by the General Partner required for it to maintain its status as a REIT for federal income tax purposes. With respect to the Series J Preferred Units, all references in this Article 29 to “past Series J Preferred Unit Distribution Periods” shall mean, as of any date, Series J Preferred Unit Distribution Periods ending on or prior to such date, and with respect to any other class or series of OP Units ranking on a parity as to distributions with the Series J Preferred Units, all references in this Article 29 to “past distribution periods” (and all similar references) shall mean, as of any date, distribution periods with respect to such other class or series of OP Units ending on or prior to such date.

(ii)When full cumulative distributions for all past Series J Preferred Unit Distribution Periods are not paid in full (or a sum sufficient for such full payment is not set apart) upon the Series J Preferred Units and when full cumulative distributions for all past distribution periods are not paid in full (or a sum sufficient for such full payment is not set apart) upon the units of any other Series J Parity Preferred Units ranking on a parity as to distributions with the Series J Preferred Units, then all distributions authorized on the Series J Preferred Units and any other outstanding classes or series of Series J Parity Preferred Units ranking on a parity as to distributions with the Series J Preferred Units shall be declared pro rata so that the amount of distributions authorized per unit on the Series J Preferred Units and such other classes or series of Series J Parity Preferred Units ranking on a parity as to distributions with the Series J Preferred Units shall in all cases bear to each other the same ratio that accumulated and unpaid distributions per unit on the Series J Preferred Units and such other classes or series of Series J Parity Preferred Units ranking on a parity as to distributions with the Series J Preferred Units (which, in the case of any such other classes or series of Series J Parity Preferred Units ranking on a parity as to distributions with the Series J Preferred Units, shall not include any accumulation in respect of unpaid distributions for past distribution periods if such other Series J Parity Preferred Units ranking on a parity as to distributions with the Series J Preferred Units does not have a cumulative distribution) bear to each other.

(a)Distributions. Upon any voluntary or involuntary liquidation, dissolution or winding-up of the Partnership, before any payment or distribution of the assets of the Partnership (whether capital or surplus) shall be made to or set apart for the holders of Common OP Units or any other classes or series of OP Units ranking junior to the Series J Preferred Units as to distributions or as to the distribution of assets upon liquidation, dissolution or winding up of the Partnership, the holders of Series J Preferred Units shall be entitled to receive an amount per Series J Preferred Unit equal to the Series J Issue Price plus any accrued but unpaid Series J Priority Return thereon (whether or not authorized or declared) to the date of payment in accordance with Article 12. If, upon any liquidation, dissolution or winding up of the Partnership, the assets of the Partnership, or proceeds thereof, distributable among the holders of Series J Preferred Units shall be insufficient to pay the full preferential amount set forth in Article 12 and liquidating payments on any Series J Parity Preferred Units, as to the distribution of assets on any liquidation, dissolution or winding up of the Partnership, then such assets, or the proceeds thereof, shall be distributed among the holders of Series J Preferred Units and any such other Series J Parity Preferred Units ratably in accordance with the respective amounts that would be payable on such Series J Preferred Units and any such Series J Parity Preferred Units if all amounts payable thereon were paid in full.

(b)Notice. Written notice of any voluntary or involuntary liquidation, dissolution or winding-up of the Partnership, 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 (i) fax or email and (ii) by first class mail, postage pre-paid, not less than thirty (30) and not more than sixty (60) days prior to the payment date stated therein, to each record holder of the Series J Preferred Units at the respective addresses of such holders as the same shall appear on the transfer records of the Partnership.

(c)No Further Rights. After payment of the full amount of the liquidating distributions to which it is entitled, the holders of Series J Preferred Units will have no right or claim to any of the remaining assets of the Partnership.

(d)Consolidation, Merger or Certain Other Transactions.

Section 29.5      Ranking

    The Series J Preferred Units rank, with respect to rights to the payment of distributions and the distribution of assets in the event of any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, (i) senior to all Common OP Units, Series A-3 Preferred Units and all other OP Units other than OP Units referred to in clauses (ii) and (iii) of this sentence; (ii) on a parity with all Series J Parity Preferred Units and (iii) junior to all Preferred OP Units, Series A-1 Preferred Units, Series A-4 Preferred Units, Series C Preferred Units, Series D Preferred Units, Series E Preferred Units, Series F Preferred Units, Series G Preferred Units, Series H Units, Series I Units and all other OP Units (now existing or hereafter

Section 29.8    Exchange Rights.

(a)    Series J Preferred Units. Each holder of Series J Preferred Units shall be entitled to exchange Series J Preferred Units for REIT Shares, at such holder’s option, on the following terms and subject to the following conditions:

    (i)    At any time after the Series J Issuance Date, subject to the terms of any lock-up agreement to which a holder is a party, each holder of Series J Preferred Units at its option may exchange each of its Series J Preferred Units for that number of REIT Shares equal to the quotient obtained by dividing the Series J Issue Price by $165; provided, however, that no Series J Preferred Units may be exchanged on any proposed Series J Exchange Date pursuant to this Section 29.8 unless at least 1,000 Series J Preferred Units, in the aggregate, are exchanged by one or more holders thereof on such Series J Exchange Date pursuant to Series J Exchange Notices. Each holder of Series J Preferred Units that has delivered a Series J Exchange Notice to the General Partner may rescind such Series J Exchange Notice by delivering written notice of such rescission to the General Partner prior to the Series J Exchange Date specified in the applicable Series J Exchange Notice.

    (ii)    The exchange rate is subject to adjustment upon subdivisions, stock splits, stock dividends, combinations and reclassification of REIT Shares. The adjustment to the exchange rate will be determined by the General Partner such that each Series J Preferred Unit will thereafter be exchangeable into the kind and amount of shares of common or other capital stock which would have been received if the exchange had occurred immediately prior to the record date for such subdivision, stock split, stock dividend, combination or reclassification of the REIT Shares.

    (iii)    In case the General Partner shall be a party to any transaction (including, without limitation, a merger, consolidation, statutory share exchange, tender offer for all or substantially all of the General Partner's capital stock or sale of all or substantially all of the General Partner's assets), in each case as a result of which the REIT Shares will be converted into the right to receive shares of capital stock, other securities or other

9

property (including cash or any combination thereof), each Series J Preferred Unit will thereafter be convertible or exchangeable into the kind and amount of shares of capital stock and other securities and property receivable (including cash or any combination thereof) upon the consummation of such transaction by a holder of that number of REIT Shares or fraction thereof into which one Series J Preferred Unit was convertible or exchangeable immediately prior to such transaction.

    (iv)    Limitations on Exchange. Notwithstanding anything to the contrary in this Section 29.8(a):

(A)    Upon tender of any Series J Preferred Units to the General Partner for REIT Shares pursuant to this Section, instead of issuing the requisite number of REIT Shares to the exchanging holder of Series J Preferred Units, the Partnership may elect to make a cash payment to the exchanging holder of Series J Preferred Units in an amount equal to the product of (i) the Common Stock Fair Market Value determined as of the Series J Exchange Date and (ii) the number of REIT Shares that would have been otherwise issued to the exchanging holder of Series J Preferred Units, for any reason or no reason, including to the extent necessary to prevent the recipient from violating the Ownership Limitations of Section 2 of Article VII of the Charter, or corresponding provisions of any amendment or restatement thereof;

(B)    A holder of Series J Preferred Units will not have the right to exchange Series J Preferred Units for REIT Shares if (1) in the opinion of counsel for the General Partner, the General Partner would no longer qualify or its status would be seriously compromised as a REIT under the Code as a result of such exchange; or (2) such exchange would, in the opinion of counsel for the General Partner, constitute or be likely to constitute a violation of applicable securities laws; and

(C)    The General Partner shall not be required to issue fractions of REIT Shares upon exchange of Series J Preferred Units. If any fraction of a REIT Share would be issuable upon exchange of Series J Preferred Units, the General Partner shall, in lieu of delivering such fraction of a REIT Share, make a cash payment to the exchanging holder of Series J Preferred Units in an amount equal to the same fraction of the Common Stock Fair Market Value determined as of the Series J Exchange Date.

(v)    Reservation of REIT Shares. The General Partner shall at all times reserve and keep available a sufficient number of authorized but unissued REIT Shares to permit the exchange of all of the outstanding Series J Preferred Units pursuant to this Section 29.8.

(b)    Procedure for Exchange.

    (i)    Any exchange described in Section 29.8(a) above shall be exercised pursuant to a delivery of a Series J Exchange Notice to the General Partner by the holder who is exercising such exchange right, by (A) fax or email and (B) by certified mail

10

postage prepaid. The Series J Exchange Notice and certificates, if any, representing such Series J Preferred Units to be exchanged shall be delivered to the office of the General Partner maintained for such purpose. Currently, such office is:

    (ii)    Any exchange hereunder shall be effective as of the close of business on the Series J Exchange Date. The holders of the exchanged Series J Preferred Units shall be deemed to have surrendered the same to the General Partner, and the General Partner shall be deemed to have issued the corresponding number of REIT Shares at the close of business on the Series J Exchange Date.

(c)    Payment of Series J Priority Return. On the Series J Preferred Unit Distribution Payment Date next following the Series J Exchange Date, the holders of Series J Preferred Units, which exchanged on such date shall be entitled to Series J Priority Return in an amount equal to a prorated portion of the Series J Priority Return based on the number of days elapsed from the prior Series J Preferred Unit Distribution Payment Date through, but not including, the Series J Exchange Date, less (ii) the amount of the distribution or dividend, if any, paid on the securities into which the Series J Preferred Units were exchanged for the quarterly period in which the Series J Exchange Date occurred.

Any such notice shall be irrevocable.

            (ii)    The Partnership will pay the Series J Redemption Price to such holder of Series J Preferred Units upon surrender of the Series J Preferred Units by such holder of Series J Preferred Units at the place designated by the Partnership. Unless the Partnership and such holder of Series J Preferred Units agree otherwise, the Partnership will pay the Redemption Price in the same manner that the most recent distribution of Series J Priority Return was delivered to such holder of Series J Preferred Units. On and after the date of redemption, distributions will cease to accumulate on such holder’s Series J Preferred Units, unless the Partnership defaults in the payment of the Series J Redemption Price. If any date fixed for redemption of such holder’s Series J Preferred Units is not a Business Day, then payment of the Series J Redemption Price payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day falls in the next calendar year, such payment will be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date fixed for redemption. If payment of the Series J Redemption Price is improperly withheld or refused and not paid by the Partnership, distributions on such holder’s Series J Preferred Units will continue to accumulate from the original redemption date to the date of payment, in which case the actual payment date will be considered the date fixed for redemption for purposes of calculating the Series J Redemption Price.

Section 29.10    No Sinking Fund.

    No sinking fund shall be established for the retirement or redemption of Series J Preferred Units.

Section 29.11    Status of Reacquired Units.

    All Series J Preferred Units which shall have been issued and reacquired in any manner by the Partnership shall be deemed cancelled and no longer outstanding.
