$0.01 par value per share

HRPT PROPERTIES TRUST, a Maryland real estate investment trust (the “ Trust ”), having its principal office in Newton, Massachusetts, hereby certifies to the State Department of Assessments and Taxation of Maryland that:

FIRST: Pursuant to authority expressly vested in the Trustees by Section 6.1 of the Third Amendment and Restatement of Declaration of Trust of the Trust, dated July 1, 1994, as amended and supplemented (the “ Declaration ”), the Trustees have duly classified and designated 15,180,000 Preferred Shares of the Trust as 6-1/2% Series D Cumulative Convertible Preferred Shares, $0.01 par value per share, of the Trust (“ Series D Preferred Shares ”).

SECOND: The preferences, rights, voting powers, restrictions, limitations as to dividends and other distributions, qualifications and terms or conditions of redemption of the Series D Preferred Shares are as follows, which upon any restatement of the Declaration shall be made part of Article VI of the Declaration, with any necessary or appropriate changes to the enumeration or lettering of sections or subsections hereof. Capitalized terms used in this ARTICLE SECOND which are defined in the Declaration and not otherwise defined herein are used herein as so defined in the Declaration. Certain additional capitalized terms used in this ARTICLE SECOND are used as defined in Section 15 below, which definitions shall apply only to Series D Preferred Shares and shall not affect the definition of such terms as used or as otherwise defined with respect to other series of Preferred Shares or elsewhere in the Declaration.

6-1/2% Series D Cumulative Convertible Preferred Shares, $0.01 par value per share

1. Designation and Number . A series of Preferred Shares, designated the 6-1/2% Series D Cumulative Convertible Preferred Shares, $0.01 par value per share (the “ Series D Preferred Shares ”), is hereby established. The number of authorized Series D Preferred Shares is 15,180,000.

2. Relative Seniority . In respect of rights to receive dividends and to participate in distributions or payments in the event of any liquidation, dissolution or winding up of the Trust, the Series D Preferred Shares shall rank (i) senior to the Common Shares, the Junior Participating Preferred Shares and any other class or series of Shares of the Trust, the terms of which specifically provide that such class or series ranks, as to rights to receive dividends and to participate in distributions or payments in the event of any liquidation, dissolution or winding up of the Trust, junior to the Series D Preferred Shares (the Shares described in this clause (i) being, collectively, “ Junior Shares ”), (ii) on a parity with the 8-3/4 % Series B Cumulative Redeemable Preferred Shares, $0.01 par value per share (the “ Series B Preferred Shares ”), the 7-1/8% Series C Cumulative Redeemable Preferred Shares, $0.01 par value per share (the “ Series C Preferred Shares ”), and any other class or series of Shares of the Trust, the terms of which specifically provide that such class or series ranks, as to rights to receive dividends and to participate in distributions or payments in the event of any liquidation, dissolution or winding up

of the Trust, on a parity with the Series D Preferred Shares, and (iii) junior to any class or series of Shares of the Trust, the terms of which specifically provide that such class or series ranks, as to rights to receive dividends and to participate in distributions or payments in the event of any liquidation, dissolution or winding up of the Trust, senior to the Series D Preferred Shares. For the avoidance of doubt, debt securities of the Trust which are convertible into or exchangeable for Shares of the Trust or any other debt securities of the Trust do not constitute a class or series of Shares for purposes of this Section 2.

Dividends and Distributions .

(a) Subject to the preferential rights of the holders of any class or series of Shares of the Trust ranking senior to the Series D Preferred Shares as to dividends, the holders of the then outstanding Series D Preferred Shares shall be entitled to receive, when and as authorized by the Trustees and declared by the Trust, out of any funds legally available therefor, cumulative cash dividends at a rate of 6.50% of the $25.00 liquidation preference per year (equivalent to $1.625 per share per year) (the “ Dividend Rate ”). Such dividends shall accrue and be cumulative from October 11, 2006 (the “ Original Issue Date ”), and will be payable quarterly in arrears in cash on the fifteenth day of each February, May, August and November beginning on February 15, 2007 (each such day being hereinafter called a “ Dividend Payment Date ”); provided that if any Dividend Payment Date is not a Business Day (as hereinafter defined), then the dividend which would otherwise have been payable on such Dividend Payment Date may be paid on the next succeeding Business Day with the same force and effect as if paid on such Dividend Payment Date, and no interest or additional dividends or other sums shall accrue on the amount so payable from such Dividend Payment Date to such next succeeding Business Day. As used herein, the term “ Dividend Period ” for Series D Preferred Shares means the period from the Original Issue Date or other date of the original issuance thereof, as applicable, and ending on and excluding the next following Dividend Payment Date, and each subsequent period from a Dividend Payment Date and ending on and excluding the next following Dividend Payment Date. The amount of any dividend payable for any full Dividend Period or portion thereof shall be computed on the basis of a 360-day year of twelve 30-day months (it being understood that the first Dividend Period is longer than a full Dividend Period). Dividends shall be payable to holders of record as they appear in the share records of the Trust at the close of business on the applicable record date (each, a “ Dividend Record Date ”), which shall be a date designated by the Trustees for the payment of dividends that is not more than 60 nor less than 10 days prior to the applicable Dividend Payment Date.

(b) Dividends on the Series D Preferred Shares shall accrue and be cumulative, whether or not (i) the Trust has earnings, (ii) there are funds legally available for the payment of such dividends or (iii) such dividends have been declared or authorized.

(c) If Series D Preferred Shares are outstanding, no full dividends shall be declared or paid or set apart for payment on any other class or series of Shares of the Trust ranking, as to dividends, on a parity with the Series D Preferred Shares for any period, unless the full cumulative dividends on the Series D Preferred Shares have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for payment for all past Dividend Periods. When dividends are not paid in full (or a sum sufficient for such full payment is not so set apart) upon the Series D Preferred Shares and the Shares of any other

- 2 -

class or series ranking on a parity as to dividends with the Series D Preferred Shares, all dividends declared upon Series D Preferred Shares and any such other class or series of Shares shall in all cases bear to each other the same ratio that accrued dividends per share on the Series D Preferred Shares and such other class or series of Shares (which shall not include any accumulation in respect of unpaid dividends for prior dividend periods if such other class or series does not have a cumulative dividend) bear to each other.

(d) Unless full cumulative dividends on the Series D Preferred Shares have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for payment for all past Dividend Periods, no dividends (other than in Common Shares or other Junior Shares or options, warrants or rights to subscribe for or purchase Common Shares or other Junior Shares) shall be declared or paid or set apart for payment and no other distribution shall be declared or made upon the Common Shares or any other Shares ranking junior to the Series D Preferred Shares as to rights to receive dividends or to participate in distributions or payments in the event of any liquidation, dissolution or winding up of the Trust, nor shall any Common Shares or any other such Shares be redeemed, purchased or otherwise acquired for any consideration (or any moneys be paid to or made available for a sinking fund for the redemption of any such Shares) by the Trust except (i) by conversion into or exchange for Common Shares or other Junior Shares, (ii) pursuant to pro rata offers to purchase or a concurrent redemption of all, or a pro rata portion of, the outstanding Series D Preferred Shares and any other class or series of Shares ranking on a parity with Series D Preferred Shares as to rights to receive dividends and to participate in distributions or payments in the event of any liquidation, dissolution or winding up of the Trust, (iii) by redemption, purchase or other acquisition of Common Shares made for purposes of an incentive, benefit or share purchase plan of the Trust or any of its subsidiaries for officers, Trustees or employees or others performing or providing similar services, (iv) by redemption, purchase or other acquisition of rights to purchase Junior Participating Preferred Shares pursuant to a Rights Plan relating to such rights or of any similar rights from time to time issued by the Trust in connection with a Rights Plan and (v) for redemptions, purchases or other acquisitions by the Trust, whether pursuant to any provision of the Declaration or otherwise, for the purpose of preserving the Trust’s status as a REIT for federal income tax purposes.

(e) No interest, or sum of money in lieu thereof, shall be payable in respect of any dividend payment or payments on Series D Preferred Shares which may be in arrears, and the holders of Series D Preferred Shares are not entitled to any dividends, whether payable in cash, securities or other property, in excess of the full cumulative dividends described in this Section 3. Except as otherwise expressly provided herein, the Series D Preferred Shares shall not be entitled to participate in the earnings or assets of the Trust.

(f) Any dividend payment made on the Series D Preferred Shares shall be first credited against the earliest accrued but unpaid dividend due with respect to such Shares which remains payable. Any cash dividends paid in respect of Series D Preferred Shares, including any portion thereof which the Trust elects to designate as “capital gain dividends” (as defined in Section 857 (or any successor provision) of the Internal Revenue Code) or as a return of capital, shall be credited to the cumulative dividends on the Series D Preferred Shares.

- 3 -

(g) No dividends on the Series D Preferred Shares shall be authorized by the Trustees or be paid or set apart for payment by the Trust at such time as the terms and provisions of any agreement of the Trust, including any agreement relating to its indebtedness, directly or indirectly prohibit authorization, payment or setting apart for payment or provide that such authorization, 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.

(h) The Trust shall remain entitled to receive and retain any interest or other earnings on any money set aside for the payment of dividends on Series D Preferred Shares and holders thereof shall have no claim to such interest or other earnings. Any funds for the payment of dividends on Series D Preferred Shares which have been set apart by the Trust and which remain unclaimed by the holders of the Series D Preferred Shares entitled thereto on the first anniversary of the applicable Dividend Payment Date, or other dividend payment date, shall revert and be repaid to the general funds of the Trust, and thereafter the holders of the Series D Preferred Shares entitled to the funds which have reverted or been repaid to the Trust shall look only to the general funds of the Trust for payment, without interest or other earnings thereon.

Liquidation Rights .

(a) Upon any voluntary or involuntary liquidation, dissolution or winding up of the Trust, before any distribution or payment shall be made to the holders of any Common Shares or any other Shares ranking junior to the Series D Preferred Shares as to rights to participate in distributions or payments in the event of any liquidation, dissolution or winding up of the Trust, but subject to the preferential rights of holders of any class or series of Shares ranking senior to the Series D Preferred Shares as to rights to participate in distributions or payments in the event of any liquidation, dissolution of winding up of the Trust, the holders of Series D Preferred Shares shall be entitled to receive, out of assets of the Trust legally available for distribution to shareholders, liquidating distributions in cash or property at its fair market value as determined by the Trustees in the amount of $25.00 per Series D Preferred Share, plus an amount equal to all dividends accrued and unpaid thereon (whether or not declared).

(b) After payment of the full amount of the liquidating distributions to which they are entitled, the holders of Series D Preferred Shares will have no right or claim to any of the remaining assets of the Trust.

(c) In the event that upon any voluntary or involuntary liquidation, dissolution or winding up of the Trust, the available assets of the Trust are insufficient to pay the full amount of the liquidating distributions on all outstanding Series D Preferred Shares and the full amounts payable as liquidating distributions on all Shares of other classes or series of Shares of the Trust ranking on a parity with the Series D Preferred Shares as to rights to participate in distributions or payments in the event of any liquidation, dissolution or winding up of the Trust, then the holders of the Series D Preferred Shares and all other such classes or series of Shares shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled.

- 4 -

(d) For purposes of this Section 4, neither the sale, lease, transfer or conveyance of all or substantially all of the property or business of the Trust, nor the merger or consolidation of the Trust into or with any other entity or the merger or consolidation of any other entity into or with the Trust or a statutory share exchange by the Trust, shall be deemed to be a dissolution, liquidation or winding up of the Trust.

(e) In determining whether a distribution (other than upon voluntary or involuntary liquidation), by dividend, redemption or other acquisition of Shares or otherwise, is permitted under Maryland law, amounts that would be needed, if the Trust were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of the holders of Series D Preferred Shares will not be added to the Trust’s total liabilities.

Redemption .

(a) The Series D Preferred Shares are not subject to mandatory or optional redemption, except as otherwise provided in Section 5(b) below and except that in certain circumstances the Trust may elect to repurchase Series D Preferred Shares as set forth in Section 10 below.

(b) The Trust may, at its option, redeem at any time all or from time to time any Series D Preferred Shares which constitute Excess Series D Preferred Shares (as defined in Section 12 below) for cash at a redemption price per share equal to $25.00, together with all accrued and unpaid dividends to the date fixed for redemption. Such redemption shall be in accordance with the same procedures set forth in Section 5 of the articles supplementary applicable to the Trust’s Series C Cumulative Redeemable Preferred Shares, as in effect on the date of these Articles Supplementary applicable to redemption thereof pursuant to Section 5(b) thereof, as though references therein to “Series C” referred to the Series D.

(c) For the avoidance of doubt, the provisions of Section 5(a) above shall not limit any direct or indirect purchase or acquisition by the Trust of all or any Series D Preferred Shares on the open market (including in privately negotiated transactions).

6. Voting Rights . Notwithstanding anything to the contrary contained in the Declaration, except as set forth below in this Section 6, the holders of the Series D Preferred Shares shall not be entitled to vote at any meeting of the shareholders for election of Trustees or for any other purpose or otherwise to participate in any action taken by the Trust or the shareholders thereof, or to receive notice of any meeting of shareholders (except for such notices as may be expressly required by law).

(a) At any time dividends on the Series D Preferred Shares shall be in arrears for six or more quarterly periods, whether or not the quarterly periods are consecutive, the holders of Series D Preferred Shares (voting separately as a class with all other series of Preferred Shares of the Trust upon which like voting rights have been conferred and are exercisable) will be entitled to vote for the election of two additional Trustees of the Trust at the next annual meeting of shareholders and for those or other replacement Trustees at each subsequent meeting (and the number of Trustees then constituting the Board of Trustees will automatically increase by two, if not already increased by two by reason of the election of Trustees by the holders of such

- 5 -

Preferred Shares), until all dividends accumulated on Series D Preferred Shares for the past Dividend Periods shall have been fully paid or declared and a sum sufficient for the payment thereof set apart for payment. For the avoidance of doubt, and by means of example, in the event dividends on the Series B Preferred Shares and Series D Preferred Shares shall each be in arrears for six or more quarterly periods, the holders of Series B Preferred Shares and Series D Preferred Shares (and the holders of all other series of Preferred Shares of the Trust upon which like voting rights have been conferred and are exercisable) shall be entitled to vote for the election of two additional Trustees in the aggregate, not four or more additional Trustees.

(i) Upon the full payment of all such dividends accumulated on Series D Preferred Shares for the past Dividend Periods or the declaration in full thereof and the Trust’s setting aside a sum sufficient for the payment thereof, the right of the holders of Series D Preferred Shares to elect such two Trustees shall cease, and (unless there are one or more other series of Preferred Shares of the Trust upon which like voting rights have been conferred and are exercisable) the term of office of such Trustees previously so elected shall automatically terminate and the authorized number of Trustees of the Trust will thereupon automatically return to the number of authorized Trustees otherwise in effect, but subject always to the same provisions for the reinstatement and divestment of the right to elect two additional Trustees in the case of any such future dividend arrearage.

(ii) If at any time when the voting rights conferred upon the Series D Preferred Shares pursuant to this Section 6(a) are exercisable any vacancy in the office of a Trustee elected pursuant to this Section 6(a) shall occur, then such vacancy may be filled only by the written consent of the remaining such Trustee or by vote of the holders of record of the outstanding Series D Preferred Shares and any other series of Preferred Shares of the Trust upon which like voting rights have been conferred and are exercisable and which are entitled to vote as a class with the Series D Preferred Shares in the election of Trustees pursuant to this Section 6(a).

(iii) Any Trustee elected or appointed pursuant to this Section 6(a) may be removed only by the holders of the outstanding Series D Preferred Shares and any other series of Preferred Shares of the Trust upon which like voting rights have been conferred and are exercisable and which are entitled to vote as a class with the Series D Preferred Shares in the election of Trustees pursuant to this Section 6(a), and may not be removed by the holders of the Common Shares.

(iv) The term of any Trustees elected or appointed pursuant to this Section 6(a) shall be from the date of such election or appointment and their qualification until the next annual meeting of the shareholders and until their successors are duly elected and qualify, except as otherwise provided above in this Section 6(a).

(b) So long as any Series D Preferred Shares remain outstanding, the Trust shall not, without the affirmative vote or consent of the holders of at least two-thirds of the Series D Preferred Shares outstanding at the time, given in person or by proxy, either in writing or at a meeting (the holders of Series D Preferred Shares voting separately as a class), (i) authorize or create, or increase the number of authorized or issued shares of, any class or series of Shares

- 6 -

ranking senior to the Series D Preferred Shares with respect to payment of dividends or the distribution of assets upon liquidation, dissolution or winding up of the Trust, or reclassify any authorized Shares of the Trust into any such Shares, or create, authorize or issue any obligation or security convertible into or evidencing the right to purchase any such Shares, or (ii) amend, alter or repeal the provisions of the Declaration or these terms of the Series D Preferred Shares, whether by merger, consolidation or otherwise, so as to materially and adversely affect any right, preference, privilege or voting power of the Series D Preferred Shares; provided, however, that any increase in the number of authorized Preferred Shares, any issuance of or increase in the number of Series D Preferred Shares or any creation or issuance of or increase in the number of authorized shares of any class or series of Preferred Shares which rank on a parity with the Series D Preferred Shares with respect to payment of dividends or the distribution of assets upon liquidation, dissolution or winding up of the Trust or which are Junior Shares shall not be deemed to materially and adversely affect the rights, preferences, privileges or voting powers of the Series D Preferred Shares.

(c) The voting provisions set forth in clauses (a) and (b) above will not apply if, at or prior to the time when the act with respect to which a vote would otherwise be required shall be effected, (i) all outstanding Series D Preferred Shares shall have been redeemed or repurchased by the Trust or (ii) all outstanding Series D Preferred Shares shall have been called for redemption or the Trust shall have exercised its election to repurchase all outstanding Series D Preferred Shares and in either case sufficient funds shall have been deposited in trust pursuant to the provisions of the terms of the Series D Preferred Shares to effect the redemption or repurchase, as applicable.

(d) On each matter submitted to a vote of the holders of Series D Preferred Shares or on which the holders of Series D Preferred Shares are otherwise entitled to vote as provided herein, each Series D Preferred Share shall be entitled to one vote, except that when Shares of any other class or series of Preferred Shares of the Trust have the right to vote with the Series D Preferred Shares as a single class on any matter, the Series D Preferred Shares and the Shares of each such other class or series will have one vote for each $25.00 of liquidation preference.

7. Conversion . Series D Preferred Shares will be convertible into Common Shares on and subject to the terms and conditions set forth below in this Section 7 and in Sections 8, 9 and 10 below.

(a)

Holder Conversion Right .

(i) Subject to and upon compliance with the provisions of this Section 7, a holder of any share or shares of Series D Preferred Shares shall have the right, at its option, to convert all or any portion of such holder’s outstanding Series D Preferred Shares (the “ Holder Conversion Right ”), subject to the conditions described below, into a number of fully paid and non-assessable Common Shares that are issuable initially at a conversion rate of 1.9231 Common Shares per $25.00 liquidation preference of Series D Preferred Shares (subject to adjustment in accordance with the provisions of Section 8 and Section 9 hereof, the “ Conversion Rate ”). The “ Conversion Price ” at any time shall be equal to $25.00 divided by the Conversion Rate at such time.

- 7 -

(ii) To exercise the Holder Conversion Right, a holder of Series D Preferred Shares must surrender to the Trust at its principal office or at the office of the Transfer Agent, as may be designated by the Board of Trustees, the certificate or certificates, if any, for the Series D Preferred Shares to be converted accompanied by a written notice stating that the holder of Series D Preferred Shares elects to convert all or a specified whole number of those shares pursuant to the Holder Conversion Right and specifying the name or names in which the holder wishes the certificate or certificates for the Common Shares, if any, to be issued or in which ownership of such Common Shares, if uncertificated, are to be registered (“ Conversion Notice ”).

(iii) As promptly as practicable after the surrender of the certificate or certificates, if any, for Series D Preferred Shares in accordance with Section 7(a)(ii), the receipt of the Conversion Notice and payment of all required transfer taxes, if any, or the demonstration to the Trust’s satisfaction that those taxes have been paid, (A) if Common Shares to be issued upon such conversion are certificated, the Trust shall issue and shall deliver or cause to be issued and delivered to such holder, or to such other Person on such holder’s written order (I) certificates evidencing the number of validly issued, fully paid and non-assessable full Common Shares to which the holder of the shares of Series D Preferred Shares being converted, or the holder’s transferee, shall be entitled, and (II) if less than the full number of such Series D Preferred Shares are being converted, if the Series D Preferred Shares are certificated, a new certificate or certificates, of like tenor, for the number of Series D Preferred Shares evidenced by the surrendered certificate or certificates, less the number of shares being converted (or otherwise the Trust shall cause the number of Series D Preferred Shares not being converted to remain registered in the name of such holder), or (B) if Common Shares to be issued upon such conversion are not certificated, (I) the Trust shall cause the number of validly issued, fully paid and non-assessable full Common Shares to which a holder of shares of Series D Preferred Shares being converted, or a holder’s transferee, shall be entitled to be registered in the name of such holder or such transferee, as applicable, and (II) if less than the full number of such Series D Preferred Shares are being converted, if the Series D Preferred Shares are certificated, a new certificate or certificates, of like tenor, for the number of Series D Preferred Shares evidenced by the surrendered certificate or certificates, less the number of shares being converted (or otherwise the Trust shall cause the number of Series D Preferred Shares not being converted to remain registered in the name of such holder), and (C) if a fractional interest in respect of a Common Share arising upon such conversion is to be settled in cash as provided in Section 7(c)(ii) below, a check or other transfer of funds for the cash settlement amount.

(iv) In lieu of the foregoing procedure, to the extent Series D Preferred Shares are held by DTC in global form, the beneficial owner of Series D Preferred Shares shall comply with the procedures of DTC in order to convert the owner’s beneficial interest in such Series D Preferred Shares.

(v) Each conversion pursuant to exercise of the Holder Conversion Right shall be deemed to have been made at the close of business on the date of giving the Conversion Notice and of surrendering the certificate or certificates, if any, evidencing the Series D Preferred Shares to be converted (the “ Conversion Date ”) so that the rights

- 8 -

of the holder thereof as to the Series D Preferred Shares being converted shall cease except for the right to receive Common Shares and, if applicable, cash in lieu of fractional Common Shares issuable upon such conversion, and, if applicable, the Person entitled to receive Common Shares shall be treated for all purposes as having become the record holder of those Common Shares at that time.

(vi) If a holder of Series D Preferred Shares has exercised its Fundamental Change Conversion Right with respect to Series D Preferred Shares, such Series D Preferred Shares may not be converted pursuant to exercise of a Holder Conversion Right unless such holder has timely submitted notice withdrawing the Series D Preferred Shares from conversion pursuant to the Fundamental Change Conversion Right pursuant to Section 10. If the Trust elected to repurchase Series D Preferred Shares subject to the exercise of a Fundamental Change Conversion Right in accordance with Section 10, such holder’s Holder Conversion Right with respect to the Series D Preferred Shares so subject to repurchase shall expire unless the Trust or the Transfer Agent has received the related Conversion Notice and the certificate or certificates, if any, for the Series D Preferred Shares, being converted (or, if applicable, the beneficial owner of such Series D Preferred Shares has complied with the procedures of DTC for the conversion of such Series D Preferred Shares) at or prior to 5:00 PM, New York City time, on the Business Day immediately preceding the Fundamental Change Conversion Date, unless the Trust defaults on the payment of the Fundamental Change Purchase Price.

(b)

Company Conversion Option .

(i) On or after November 20, 2011, the Trust shall have the option to convert some or all of the outstanding Series D Preferred Shares into that number of Common Shares that are issuable at the then applicable Conversion Rate (the “ Company Conversion Option ”). The Trust may exercise the Company Conversion Option only if the Closing Sale Price (as hereinafter defined) of the Common Shares equals or exceeds the then applicable Conversion Price for at least 20 Trading Days in a period of 30 consecutive Trading Days (including the last Trading Day of such period), ending on the Trading Day immediately prior to the Trust’s issuance of a press release announcing its intent to exercise the Company Conversion Option in accordance with Section 7(b)(iii).

(ii) If the Trust shall convert less than all of the outstanding Series D Preferred Shares, the Transfer Agent shall select the Series D Preferred Shares to be converted by lot, on a pro rata basis or in accordance with any other method the Transfer Agent considers fair and appropriate. The Trust may convert the Series D Preferred Shares only in a whole number of shares. If a portion of a holder’s Series D Preferred Shares is selected for partial conversion by the Trust and the holder exercises the Holder Conversion Right to convert a portion of such Series D Preferred Shares, the number of Series D Preferred Shares subject to conversion by the Trust pursuant to the Company Conversion Option shall be reduced by the number of shares that the holder converted by exercising the Holder Conversion Right.

(iii) To exercise the Company Conversion Option right set forth in this Section 7(b), the Trust shall issue a press release for publication to the Dow Jones &

- 9 -

Company, Inc., Business Wire or Bloomberg Business News (or, if such organizations are not in existence at the time of issuance of such press release, such other news or press organization as is reasonably calculated to broadly disseminate the relevant information to the public) prior to the opening of business on the first Trading Day following any date on which the conditions set forth in Section 7(b)(i) shall have been satisfied, announcing the Trust’s intention to exercise the Company Conversion Option. The Trust shall also give notice by mail or by publication (with subsequent prompt notice by mail) to the holders of the Series D Preferred Shares (not more than four (4) Trading Days after the date of the press release) announcing the Trust’s intention to exercise the Company Conversion Option. The effective date for any Company Conversion Option (the “ Company Conversion Option Date ”) shall be on the date that is five (5) Trading Days after the date on which the Trust issues such press release. In addition to any information required by applicable law or regulation, the Company Conversion Option Notice and the press release and notice with respect to the exercise of the Company Conversion Option shall state, as appropriate: (A) the Company Conversion Option Date; (B) the number of Common Shares to be issued upon conversion of each Series D Preferred Share; (C) the number of shares of Series D Preferred Shares to be converted; and (D) that dividends on the Series D Preferred Shares to be converted shall cease to accrue on the Company Conversion Option Date.

(iv) As promptly as practicable after the exercise of the Company Conversion Option and surrender to the Trust at its principal office or at the office of the Transfer Agent, as may be designated by the Board of Trustees, the certificate or certificates, if any, for the Series D Preferred Shares to be converted accompanied by a written notice specifying the name or names in which the holder wishes the certificate or certificates for the Common Shares, if any, to be issued or in which ownership of such Common Shares, if uncertificated, are to be registered, (A) if Common Shares to be issued upon such conversion are certificated, (x) the Trust shall issue and shall deliver or cause to be issued and delivered to such holder, or to such other Person on such holder’s written order (I) certificates evidencing the number of validly issued, fully paid and non-assessable full Common Shares to which a holder of shares of Series D Preferred Shares being converted, or a holder’s transferee, shall be entitled, (II) if less than the full number of such Series D Preferred Shares are being converted, if the Series D Preferred Shares are certificated, a new certificate or certificates, of like tenor, for the number of Series D Preferred Shares evidenced by the surrendered certificate or certificates, less the number of shares being converted (or otherwise the Trust shall cause the number of Series D Preferred Shares not being converted to remain registered in the name of such holder), or (B) if Common Shares to be issued upon such conversion are not certificated, (I) the Trust shall cause the number of validly issued, fully paid and non-assessable full Common Shares to which a holder of shares of Series D Preferred Shares being converted, or a holder’s transferee, shall be entitled to be registered in the name of such holder or such transferee, as applicable, and (II) if less than the full number of such Series D Preferred Shares are being converted, if the Series D Preferred Shares are certificated, a new certificate or certificates, of like tenor, for the number of Series D Preferred Shares evidenced by the surrendered certificate or certificates, less the number of shares being converted (or otherwise the Trust shall cause the number of Series D Preferred Shares not being converted to remain registered in the name of such holder),

- 10 -

and (C) if a fractional interest in respect of a Common Share arising upon such conversion is to be settled in cash as provided in Section 7(c)(ii), a check or other transfer of funds for the cash settlement amount.

(v) In lieu of the foregoing procedure, to the extent Series D Preferred Shares are held by DTC in global form, the beneficial owner of Series D Preferred Shares shall comply with the procedures of DTC upon exercise of the Company Conversion Option in order to convert the owner’s beneficial interest in such Series D Preferred Shares.

(vi) Each conversion pursuant to this Section 7(b) shall be deemed to have been made at the close of business on the Company Conversion Option Date so that the rights of the holder thereof as to the shares of Series D Preferred Shares being converted shall cease except for the right to receive Common Shares and, if applicable, cash in lieu of fractional Common Shares issuable upon such conversion, and the Person entitled to receive Common Shares shall be treated for all purposes as having become the record holder of those Common Shares at that time.

(vii) In case any Series D Preferred Share is to be converted pursuant to this Section 7(b), the holder’s right to voluntarily convert such Series D Preferred Share pursuant to exercise of the Holder Conversion Right or the Fundamental Change Conversion Right shall terminate at 5:00 p.m., New York City time, on the Business Day immediately preceding the Company Conversion Option Date.

(c)

General Provisions for Conversions .

(i) If more than one Series D Preferred Share shall be surrendered for conversion by the same holder or subject to exercise of the Company Conversion Option at the same time, the number of full Common Shares issuable on conversion of those shares of Series D Preferred Shares shall be computed on the basis of the total number of shares of Series D Preferred Shares so surrendered.

(ii) In connection with the conversion of any Series D Preferred Shares, the Trust may elect not to issue fractional Common Shares, in which case the Trust shall pay a cash adjustment in respect of any fractional interest in an amount equal to the fractional interest, multiplied by the Closing Sale Price of the Common Shares on the Trading Day immediately prior to the Conversion Date or the Company Conversion Option Date, as applicable.

(iii) In case the Conversion Notice or holder’s order pursuant to Section 7(b)(iv) specifies that the Common Shares issuable upon conversion of Series D Preferred Shares are to be issued or registered in a name or names other than that of the registered holder of Series D Preferred Shares, the notice or order shall be accompanied by payment of all transfer taxes payable upon the issuance of Common Shares in that name or names. Other than those transfer taxes payable pursuant to the preceding sentence, the Trust shall pay any documentary, stamp or similar issue or transfer taxes that may be payable in respect of any issuance or delivery of Common Shares upon conversion of Series D Preferred Shares pursuant to this Section 7.

- 11 -

(iv) A holder of Series D Preferred Shares is not entitled to any rights of a holder of Common Shares until that holder has converted its Series D Preferred Shares, and only to the extent such Series D Preferred Shares have been or are deemed to have been converted to Common Shares in accordance with the provisions of this Section 7.

(v) The Trust shall, prior to issuance of any share of Series D Preferred Shares, and from time to time as may be necessary, reserve and keep available, free from preemptive rights, out of its authorized but unissued shares of beneficial interest, for the purpose of effecting the conversion of the Series D Preferred Shares pursuant to this Section 7, such number of its duly authorized Common Shares as shall from time to time be sufficient to effect the conversion pursuant to this Section 7 of all shares of Series D Preferred Shares then outstanding into such Common Shares at any time (assuming that, at the time of the computation of such number of Common Shares, all such shares of Series D Preferred Shares would be held by a single holder). The Trust covenants that all Common Shares that may be issued upon conversion of Series D Preferred Shares shall, upon issue, be validly issued, fully paid and nonassessable and free from all liens and charges and, except as provided in Section 7(c)(iii), taxes with respect to the issue thereof and not subject to any preemptive rights. Before the delivery of any Common Shares that the Trust shall be obligated to deliver upon conversion of any shares of the Series D Preferred Shares, the Trust shall comply with all federal and state laws and regulations applicable to such conversion.

(d)

Payment of Dividends upon Conversion.

(i)

Holders Conversion Right .

(A)

If a holder of Series D Preferred Shares exercises its Holder Conversion Right, upon delivery of the Series D Preferred Shares for conversion, those Series D Preferred Shares shall cease to cumulate dividends as of the close of business on the Conversion Date and the holder shall not receive any cash payment representing accrued and unpaid dividends on the Series D Preferred Shares delivered for conversion, except in those limited circumstances discussed in this Section 7(d)(i). Except as provided herein, the Trust shall make no payment for accrued and unpaid dividends, whether or not in arrears, on Series D Preferred Shares converted at a holder’s election pursuant to a Holder Conversion Right, or for dividends on Common Shares issued upon such conversion.

(B)

If the Trust receives a Conversion Notice before the close of business on a Dividend Record Date, the holder shall not be entitled to receive any portion of the dividend payable on such converted Series D Preferred Shares on the corresponding Dividend Payment Date.

(C)

If the Trust receives a Conversion Notice after the Dividend Record Date but prior to the corresponding Dividend Payment Date, the holder of Series D Preferred Shares on the Dividend Record Date shall receive on that Dividend Payment Date accrued dividends on those Series D

- 12 -

Preferred Shares, notwithstanding the conversion of those Series D Preferred Shares prior to that Dividend Payment Date. However, at the time that such holder surrenders the Series D Preferred Shares for conversion, the holder shall pay to the Trust an amount equal to the dividend that has accrued and that shall be paid on the related Dividend Payment Date.

(D)

A holder of Series D Preferred Shares on a Dividend Record Date who exercises its Holder Conversion Right and converts such Series D Preferred Shares into Common Shares on or after the corresponding Dividend Payment Date shall be entitled to receive the dividend payable on such Series D Preferred Shares on such Dividend Payment Date, and the converting holder need not include payment of the amount of such dividend upon surrender for conversion of such Series D Preferred Shares.

(ii)

Company Conversion Option .

(A)

If the Trust exercises the Company Conversion Option, whether the Company Conversion Option Date is prior to, on or after the Dividend Record Date for the current period, all unpaid dividends which are in arrears as of the Company Conversion Option Date shall be payable to the holder of the Series D Preferred Shares with respect to which the Company Conversion Option has been exercised.

(B)

If the Trust exercises the Company Conversion Option and the Company Conversion Option Date is a date that is after the close of business on a Dividend Payment Date and prior to the close of business on the next Dividend Record Date, the holder of Series D Preferred Shares with respect to which the Company Conversion Option has been exercised shall not be entitled to receive any portion of the dividend for such period on such converted Series D Preferred Shares on the corresponding Dividend Payment Date.

(C)

If the Trust exercises the Company Conversion Option and the Company Conversion Option Date is a date that is on or after the close of business on any Dividend Record Date and prior to the close of business on the corresponding Dividend Payment Date, all dividends, including accrued and unpaid dividends, whether or not in arrears, with respect to the Series D Preferred Shares called for conversion on such date, shall be payable on such Dividend Payment Date to the record holder of Series D Preferred Shares if the record holder of such shares is the record holder of such Shares on such Dividend Record Date.

(iii) Fundamental Change Conversion Right . The provisions set forth above in this Section 7(d) shall not apply to Series D Preferred Shares which are converted into Common Shares pursuant to the Fundamental Change Conversion Right or which are repurchased by the Trust in lieu of such conversion pursuant to Section 10 below.

- 13 -

Adjustments to Conversion Rate

(a)

The Conversion Rate shall be adjusted from time to time by the Trust as follows:

(i) If Common Shares are issued as payment for dividends on Common Shares, the Conversion Rate shall be adjusted based on the following formula:

CR ¹ = CR _O x OS ₁ /OS _O

where,

CR _O	=	the Conversion Rate in effect immediately prior to such event
CR ¹	=	the Conversion Rate in effect immediately after such event
OS _O	=	the number of Common Shares outstanding immediately prior to such event
OS ₁	=	the number of Common Shares outstanding immediately after such event.

An adjustment made pursuant to this subsection (i) shall become effective on the date immediately after the date fixed for the determination of shareholders entitled to receive such dividend or other distribution. If any dividend described in this subsection (i) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(ii) If a share subdivision, combination or reclassification of Common Shares is effected, the Conversion Rate shall be adjusted based on the following formula:

CR ¹ = CR _O x OS ₁ /OS _O

where,

CR _O	=	the Conversion Rate in effect immediately prior to such event
CR ¹	=	the Conversion Rate in effect immediately after such event
OS _O	=	the number of Common Shares outstanding immediately prior to such event
OS ₁	=	the number of Common Shares outstanding immediately after such event.

An adjustment made pursuant to this subsection (ii) shall become effective on the date immediately after the date on which such subdivision, combination or reclassification becomes effective.

- 14 -

(iii) If any rights, warrants, options or other securities are issued to all or substantially all of the holders of Common Shares entitling them for a period of not more than sixty (60) days immediately following the record date for the distribution, to purchase or subscribe for Common Shares, or securities convertible into Common Shares (which for such and similar purposes hereunder shall be deemed also to include securities which are exchangeable or exercisable for Common Shares), in either case at an exercise price per share or a conversion price per share less than the Closing Sale Price per share of the Common Shares on the record date for such distribution, the Conversion Rate shall be adjusted based on the following formula:

CR ¹ = CR _O x (OS _O +X)/(OS _O +Y)

where,

CR _O	=	the Conversion Rate in effect immediately prior to such event
CR ¹	=	the Conversion Rate in effect immediately after such event
OS _O	=	the number of Common Shares outstanding immediately prior to such event
X	=	the total number of Common Shares issuable pursuant to such rights, warrants, options or other securities
Y	=	the number of Common Shares equal to the quotient of (A) the aggregate price payable to exercise of such rights, warrants, options or other securities and (B) the average of the Closing Sale Prices of Common Shares for the 10 consecutive Trading Days prior to the Business Day immediately preceding the date of announcement for the issuance of such rights, warrants, options, other securities or convertible securities.

An adjustment made pursuant to this subsection (iii) shall be made successively whenever such rights, warrants, options, other securities or convertible securities are issued, and shall become effective on the day following the date of announcement of such issuance. If, at the end of the period during which such rights, warrants, options, other securities or convertible securities are exercisable or convertible, not all rights, warrants, options, other securities or convertible securities have been exercised or converted, as the case may be, the adjusted Conversion Rate shall be immediately readjusted to what it would have been based upon the number of additional Common Shares actually issued (or the number of Common Shares actually issued upon conversion of convertible securities actually issued).

For purposes of this subsection (iii), in determining whether such rights, warrants, options, other securities or convertible securities entitle the holder to subscribe for or purchase or exercise a conversion right for Common Shares at less than the average Closing Sale Price of the Common Shares, and in determining the aggregate exercise or conversion price payable for such Common Shares, there shall be taken into account any

- 15 -

consideration received by the Trust for such rights, warrants, options, other securities or convertible securities and any amount payable on exercise or conversion thereof, with the value of such consideration, if other than cash, to be determined by the Board of Trustees.

(iv) If any shares of the Trust’s or any of the Trust’s existing or future subsidiaries’ shares of beneficial interest (other than Common Shares), evidences of indebtedness or other assets (other than distributions covered by subsections (v) and (vi) below) or rights, warrants, options or other securities or convertible securities which entitle the holder to subscribe for or purchase or exercise a conversion right for securities of the Trust (other than those covered by subsection (iii) above or referred to in Section 8(i) below relating to Rights Plans) (collectively, subject to such exclusions, “ Distributed Assets ”), the Conversion Rate in effect immediately before the close of business on the ex-distribution date shall be adjusted, based on the following formula:

CR ¹ = CR _O x SP _O /(SP _O - FMV)

where

CR _O	=	the Conversion Rate in effect immediately prior to such distribution
CR ¹	=	the Conversion Rate in effect immediately after such distribution
SP _O	=	the average of the Closing Sale Prices of Common Shares for the 10 consecutive Trading Days prior to the Business Day immediately preceding the ex-dividend date for such distribution
FMV	=	the fair market value (as determined in good faith by the Board of Trustees) of such Distributed Assets distributed with respect to each outstanding Common Share on the record date for such distribution.

Notwithstanding the foregoing, the Trust shall not adjust the Conversion Rate pursuant to this paragraph for distributions of rights, warrants, options or other securities or convertible securities, if adequate provision shall be made (as determined in good faith by the Board of Trustees) so that the holder of each Series D Preferred Share shall have the right to receive on the date, if any, on which such Series D Preferred Share is converted into Common Shares, the amount of such Distributed Assets such holder of such Series D Preferred Share would have received had such holder of such Series D Preferred Share owned a number of Common Shares equal to the Conversion Rate on the record date for such distribution.

With respect to an adjustment pursuant to this subsection (iv) where there has been a payment or distribution on Common Shares or capital shares of any class or series, or similar equity interest, of or relating to a subsidiary or other business unit (a “spin-off”), the Conversion Rate in effect immediately before the close of business on the ex-distribution date shall be increased, based on the following formula instead of the formula set forth above in this subsection (iv):

CR ¹ = CR _O x (FMV _O + MP _O )/MP _O

- 16 -

where,

CR _O	=	the Conversion Rate in effect immediately prior to such distribution
CR ¹	=	the Conversion Rate in effect immediately after such distribution
FMV _O	=	the average of the Closing Sale Prices of the capital shares or similar equity interest distributed to holders of Common Shares applicable to one Common Share over the first 10 Trading Days after the effective date of the spin-off
MP _O	=	the average of the Closing Sale Prices of Common Shares over the first 10 consecutive Trading Days after the effective date of the spin-off.

The adjustment to the Conversion Rate under the preceding paragraph with respect to a spin-off shall occur on the tenth Trading Day from, and including, the effective date of the spin-off.

If any such distribution or distribution described in this subsection (iv) is declared but not paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such distribution had not been declared.

(v) If any cash dividend or distribution is paid or made during any of the Trust’s quarterly fiscal periods to all or substantially all of the holders of Common Shares in an aggregate amount that, together with all other cash dividends and distributions made during such quarterly fiscal period, exceeds the Distribution Threshold times the number of Common Shares outstanding on the record date for such dividend or distribution, other than distributions covered by subsection (vi) below, the Conversion Rate shall be adjusted based on the following formula:

CR ¹ = CR _O x SP _O /(SP _O - C)

where,

CR _O	=	the Conversion Rate in effect immediately prior to the record date for such distribution
CR ¹	=	the Conversion Rate in effect immediately after the record date for such distribution
SP _O	=	the average of the Closing Sale Prices of Common Shares for the 10 consecutive Trading Days prior to the Business Day immediately preceding the Dividend Record Date of such distribution
C	=	(A) in the case of a regular quarterly dividend or distribution, the amount in cash per share the Trust distributes to holders of Common Shares that exceeds the Distribution Threshold then in effect or (B) in any other case, the full amount of such dividend or distribution.

- 17 -

An adjustment made pursuant to this subsection (v) shall become effective on the date immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution. If any dividend or distribution described in this subsection (v) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such distribution had not been declared.

The initial “ Distribution Threshold ” shall be $0.21. In the event the Conversion Rate is adjusted pursuant to this Section 8, other than an adjustment in respect of a regular quarterly dividend or distribution pursuant to this subsection (v), the Distribution Threshold shall be concurrently adjusted multiplying the Distribution Threshold in effect immediately before the adjustment by a fraction, the numerator of which is the Conversion Rate in effect immediately before the adjustment, and the denominator of which is the adjusted Conversion Rate.

(vi) If distributions of cash or other consideration by the Trust or any of its subsidiaries in respect of a tender offer or exchange offer for Common Shares, where such cash and the value of any such other consideration per Common Share validly tendered or exchanged exceeds the Closing Sale Price per Common Share on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to the tender or exchange offer (the “ Expiration Date ” and the last time at which such tenders or exchanges could have been made on the Expiration Date being the “ Expiration Time ”) on the following formula:

CR ¹ = CR _O x (AC + (SP ₁ x OS ₁ ))/(OS _O x SP ₁ )

where,

CR _O	=	the Conversion Rate in effect on the Expiration Date
CR ¹	=	the Conversion Rate in effect on the day next succeeding the Expiration Date
AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Trustees) paid or payable for Common Shares purchased in such tender or exchange offer
OS _O	=	the number of Common Shares outstanding immediately prior to the Expiration Time
OS ₁	=	the number of Common Shares outstanding immediately after the date such tender or exchange offer expires
SP ₁	=	the average of the Closing Sale Prices of Common Shares for the 10 consecutive Trading Days commencing on the Trading Day next succeeding the Expiration Date

- 18 -

If, however, the application of the foregoing formula would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made.

Any adjustment made pursuant to this subsection (vi) shall become effective on the date immediately prior to the open of business on the day following the Effective Date. If the Trust is obligated to purchase Common Shares pursuant to any such tender or exchange offer, but the Trust is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would be in effect if such tender or exchange offer had not been made.

(b) If the Trust issues any rights, warrants, options or other securities entitling the holders thereof to purchase or subscribe for Common Shares or securities convertible into Common Shares only upon the occurrence of certain triggering events, then:

(i) the Conversion Rate shall not be adjusted pursuant to Section 8(a) above until the earliest of these triggering events occurs; and

(ii) the Conversion Rate shall be readjusted to the extent any of these rights, options or warrants are not exercised before they expire.

(c) The Conversion Rate shall not be adjusted for any of the transactions described in Section 8(a) if the Trust makes provisions for each holder of Series D Preferred to participate in the transaction without conversion as if such holder held the number of shares equal to the Conversion Rate in effect on the “ex-date” or effective date, as the case may be, for such transaction multiplied by the number of Series D Preferred Shares held by such holder.

(d) The Conversion Rate shall not be adjusted pursuant to the provisions above unless the adjustment would result in a change of at least 1% in the then effective Conversion Rate. Any adjustment that would otherwise have been made shall be taken into account in any subsequent adjustment. In addition, at the end of each fiscal year, beginning with the fiscal year ending on December 31, 2007, any adjustments that have otherwise deferred pursuant to this subsection (d) shall be given effect, and those adjustments, if any, shall no longer be carried forward or taken into account in any subsequent adjustment. If a Fundamental Change occurs, all adjustments that have otherwise deferred pursuant to this subsection (d) shall be given effect.

(e) To the extent permitted by law and the continued listing requirements of the NYSE or any other securities exchange on which Common Shares may then be listed, the Board of Trustees may, from time to time, increase the Conversion Rate by any amount for a period of at least 20 days or any longer period required by law, so long as the increase is irrevocable during that period and the Board of Trustees determines that the increase is in the Trust’s best interests. Any such determination by the Board of Trustees shall be conclusive. The Trust shall mail a notice of the increase to holders of Series D Preferred Shares at least 15 days before the day the increase commences.

(f) The Board of Trustees may from time to time make such additional increases in the Conversion Rate, in addition to those otherwise required or permitted by this Section 8, if the Board determines that it is advisable, in order that any dividend or distribution of Common

- 19 -

Shares or other capital shares, any subdivision, reclassification or combination of Common Shares or other capital shares, or any issuance of options, warrants or other rights to acquire Common Shares or other capital shares, or any event treated as such for United States federal income tax purposes, shall not be taxable to the holders of such Common Shares, capital shares, options, warrants or other right for United States federal income tax purposes or to diminish any such tax. The Trust shall mail a notice of the increase to holders of Series D Preferred Shares at least 15 days before the day the increase commences.

(g) Notwithstanding the other provisions of this Section 8, the Conversion Rate shall not be adjusted:

(i) upon the issuance of any Common Shares pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Trust’s securities and the investment of additional optional amounts in Common Shares under any plan;

(ii) upon the issuance of any Common Shares or options or rights to purchase Common Shares pursuant to, or the repurchase by the Trust of Common Shares or such options or rights pursuant to, any present or future employee, trustee, manager or consultant incentive or benefit plan or program of or assumed by the Trust or any of the Trust’s subsidiaries;

(iii)

for a change in the par value of the Common Shares; or

(iv)

for accumulated and unpaid dividends.

(h) The following provisions shall apply if a Business Combination shall occur a result of which the holders of the Trust’s Common Shares are entitled to receive stock, other securities, other property or assets (including cash or any combination thereof) with respect to or in exchange for Common Shares:

(i) The Trust or the successor or purchasing Person, as the case may be, shall provide that each holder of Series D Preferred Shares shall be entitled thereafter to convert such Series D Preferred Shares into the kind and amount of stock, other securities or other property or assets (including cash or any combination thereof) which such holder of Series D Preferred Shares would have owned or been entitled to receive upon such Business Combination as if such holder of Series D Preferred Shares held a number of Common Shares equal to the Conversion Rate as of the effective date for such Business Combination, multiplied by the number of shares of Series D Preferred Shares held by such holder; provided that with respect to a Business Combination that also constitutes a Fundamental Change, such holder of Series D Preferred Shares shall not be entitled to receive any Additional Shares if such holder does not convert its Series D Preferred Shares in connection with the relevant Fundamental Change pursuant to Section 10(a). In the event that holders of Common Shares have the opportunity to elect the form of consideration to be received in such Business Combination, the Trust shall make adequate provision whereby the holders of Series D Preferred Shares shall have a reasonable opportunity to determine the form of consideration into which all of the

- 20 -

Series D Preferred Shares, treated as a single class, shall be convertible from and after the effective date of such Business Combination. Such determination shall be based on the weighted average of elections made by the holders of Series D Preferred Shares who participate in such determination, shall be subject to any limitations to which all of the holders of Common Shares are subject (such as pro rata reductions applicable to any portion of the consideration payable in such Business Combination), and shall be conducted in such a manner as to be completed by the date which is the earliest of (A) the deadline for elections to be made by holders of Common Shares, and (B) two Trading Days prior to the anticipated effective date of the Business Combination.

(ii) The Trust shall provide notice of the opportunity to determine the form of such consideration, as well as notice of the determination made by the holders of Series D Preferred Shares (and the weighted average of elections), by posting such notice with DTC and providing a copy of such notice to the Transfer Agent. If the effective date of a Business Combination is delayed beyond the initially anticipated effective date, holders of Series D Preferred Shares shall be given the opportunity to make subsequent similar determinations in regard to such delayed effective date.

(iii) If this Section 8(h) applies to any event or occurrence would otherwise result in an adjustment to the Conversion Rate pursuant to this Section 8, such adjustment shall not occur or apply.

(iv) The above provisions of this Section 8(h) shall similarly apply to successive Business Combinations. The Trust shall not become a party to any Business Combination to which this Section 8(h) is applicable unless its terms are consistent in all material respects with the provisions of this Section 8(h).

(v) None of the provisions of this Section 8(h) shall affect the right of a holder of Series D Preferred Shares to convert its shares of Series D Preferred Shares into Common Shares prior to the effective date of a Business Combination.

(i) To the extent that a Rights Plan is in effect at the time of conversion of any Series D Preferred Share into Common Shares, upon such conversion, the converting holder shall receive, in addition to Common Shares, the rights under such Rights Plan, unless the rights have expired, terminated or been redeemed or unless the rights have separated from Common Shares prior to the time of conversion, in which case the Conversion Rate shall be adjusted (subject to the other provisions of this Section 8, including without limitation Section 8(c)), at the time of separation as if the Trust made a distribution thereof covered by Section 8(a)(iv) above, subject to readjustment in the event of the expiration, termination or redemption of such rights.

(j) No adjustment to the Conversion Rate shall be required in connection with any event, transaction or other occurrence unless these terms of the Series D Preferred Shares specifically require that such an adjustment be made in connection with such event, transaction or other occurrence.

- 21 -

(k) All adjustments to the Conversion Rate under this Section 8 or Section 9 or 10 shall be made by the Trust and shall be calculated to the nearest one ten thousandth (1/10,000) of a share. Notwithstanding anything in these terms of the Series D Preferred Shares to the contrary, in no event shall the Conversion Rate be adjusted so that the Conversion Price would be less than $0.01, subject to adjustment for share splits and combinations, reclassifications and similar events affecting the Common Shares.

(l) In any case in which this Section 8 provides that an adjustment shall become effective immediately after (A) a record date for an event, (B) the date fixed for the determination of shareholders entitled to receive a distribution pursuant to Section 8(a)(i), (C) a date fixed for the determination of shareholders entitled to receive rights, warrants, options or other securities pursuant to Section 8(a)(iii) or (D) the Expiration Time for any tender or exchange offer pursuant to Section 8(a)(vi) (each a “ Determination Date ”), the Trust may elect to defer until the occurrence of the applicable Adjustment Event (x) issuing to each holder of Series D Preferred Shares (or portion thereof) converted after such Determination Date and before the occurrence of such Adjustment Event, the additional Common Shares or other securities issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the Common Shares issuable upon such conversion before giving effect to such adjustment and (y) settling fractional shares in the manner set forth in Section 7(c)(ii); provided that in the case of an adjustment made pursuant to Section 8(a)(iv) with respect to a distribution of capital shares of, or similar equity interest in, a subsidiary or other business unit of the Trust, the Trust may defer the issuance of such additional shares and cash payment, if any, until the third Business Day immediately following the last day of the 20 consecutive Trading Day period commencing on the fifth Trading Day after the Ex Distribution Date. For purposes of this Section 8(l), the term “ Adjustment Event ” shall mean:

(i) in any case referred to in clause (A) hereof, the occurrence of such event;

(ii) in any case referred to in clause (B) hereof, the date any such distribution is paid or made;

(iii) in any case referred to in clause (C) hereof, the date of expiration of such rights, warrants, options or other securities (or the conversion period of any convertible securities issued upon exercise thereof); and

(iv) in any case referred to in clause (D) hereof, the date a sale or exchange of Common Shares pursuant to such tender or exchange offer is consummated and becomes irrevocable.

(m) Whenever an adjustment in the Conversion Rate with respect to the Series D Preferred Shares is required:

(i) the Trust shall forthwith place on file with the Transfer Agent a certificate of its chief financial officer (or such person having similar responsibilities of the Trust), stating the adjusted Conversion Rate determined as provided herein and setting forth in reasonable detail such facts as shall be necessary to show the reason for and the manner of computing such adjustment; and

- 22 -

(ii) a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate shall forthwith be given by the Trust to each holder of Series D Preferred Shares. Any such notice so given shall be conclusively presumed to have been duly given, whether or not the holder receives such notice, and any failure to give such notice or any defect therein shall not affect the legality or validity of any such adjustment.

(n)

In case:

(i) the Trust shall declare a dividend or any other distribution on its Common Shares that would require an adjustment in the Conversion Rate pursuant to Section 8(a); or

(ii) the Trust shall authorize the granting to the holders of all or substantially all of the Common Shares of rights, warrants, options or other securities to subscribe for or purchase any share of any class of shares of beneficial interest of the Trust or any other rights, warrants, options or other securities of the Trust; or

(iii) of any reclassification or reorganization of the Common Shares (other than a subdivision or combination of the outstanding Common Shares, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Trust is a party and for which approval of any shareholders of the Trust is required, or of the sale or transfer of all or substantially all of the assets of the Trust; or

(iv) of the voluntary or involuntary dissolution, liquidation or winding up of the Trust;

the Trust shall cause to be mailed to each holder of Series D Convertible Shares at its address appearing in the records of the Trust, as promptly as possible but in any event at least ten (10) days prior to the applicable date hereinafter specified, a notice stating (A) the date on which a record is to be taken for the purpose of such, distribution or grant, or, if a record is not to be taken, the date as of which the holders of Common Shares of record to be entitled to such, distribution or grant are to be determined, or (B) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of Common Shares of record shall be entitled to exchange their Common Shares for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. In the event any of the foregoing events described in clause (i) through (iv) above is a Make-Whole Fundamental Change, this notice pursuant to this Section 8(n) may be combined with the notice to be provided pursuant to Section 9(c) below. Failure to give a notice pursuant to this Section 8(n), or any defect therein, shall not affect the legality or validity of such dividend, distribution, grant, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

Adjustment to Conversion Rate Upon a Fundamental Change

- 23 -

(a) If and only to the extent a holder of Series D Preferred Shares elects to convert its Series D Preferred Shares pursuant to Section 8(a) in connection with a Make-Whole Fundamental Change, the Trust shall increase the Conversion Rate applicable to the shares of Series D Preferred Shares surrendered for conversion by a number of additional shares (the “ Additional Shares ”), if any, as set forth in this Section 9. A conversion shall be deemed for the purposes of this Section 9(a) to be “in connection with” a Fundamental Change if the applicable Conversion Notice is received by the Transfer Agent from and including the Effective Date of such Fundamental Change up to and including the Fundamental Change Conversion Date for that Fundamental Change. If a holder elects to convert Series D Preferred Shares in connection with a Fundamental Change, but such Fundamental Change is not consummated, then such holder shall not be entitled to the increased Conversion Rate referred to above in connection with the conversion.

The number of Additional Shares, if any, shall be determined by reference to the table below, based on the Effective Date of such Fundamental Change and the Share Price for such Fundamental Change. If an event occurs that requires an adjustment to the Conversion Rate as described in Section 8, each applicable Share Price set forth in the first column of the table below shall be adjusted, concurrently with such adjustment in the Conversion Rate, multiplying the Share Price in effect immediately before the adjustment by a fraction, the numerator of which is the Conversion Rate in effect immediately before the adjustment, and the denominator of which is the adjusted Conversion Rate. In addition, but without duplication of the adjustment pursuant to the preceding sentence, if an event occurs that requires an adjustment to the Conversion Rate as described in Section 8, each applicable number of Additional Shares set forth in the table below shall be adjusted concurrently and in the same manner in which the Conversion Rate is adjusted as described in Section 8.

Number of Additional Shares (per $25.00 liquidation preference of Series D Preferred Shares)
	Effective Date

(b) The exact applicable Share Price and Effective Date may not be as set forth in the table above, in which case:

(i) if the actual applicable Share Price is between two applicable Share Price listed in the table above, or the actual effective date is between two dates listed in the table above, the Trust shall determine the number of additional shares by linear interpolation between the numbers of additional shares set forth for the two applicable prices, or for the two dates based on a 365-day year, as applicable;

Fundamental Change Conversion Right and Repurchase Right .

(a) Subject to and upon compliance with the provisions of this Section 10, in the event of a Fundamental Change occurs, a holder of any share or shares of Series D Preferred Shares shall have the right, at its option and in addition to its Holder Conversion Right, to convert all or any portion of such holder’s outstanding Series D Preferred Shares (the “ Fundamental Change Conversion Right ”) on the applicable Fundamental Change Conversion Date into the number of fully paid and non-assessable Common Shares per $25.00 liquidation preference of Series D Preferred Shares equal to such liquidation preference plus accrued and unpaid dividends to but not including such Fundamental Change Conversion Date divided by 98% of the Market Price of Common Shares (such rate of conversion being the “ Fundamental Change Conversion Rate ”). The Fundamental Change Conversion Right shall be exercisable as provided below in this Section 10.

(b) If the Fundamental Change Conversion Right has been exercised with respect to Series D Preferred Shares, the Trust shall have the right (the “ Repurchase Right ”), at its election and in lieu of such conversion, to repurchase some or all of such Series D Preferred Shares for a

- 25 -

repurchase price per share equal to the $25.00 liquidation preference of such Series D Preferred Share plus accrued and unpaid dividends to, but not including, such Fundamental Change Conversion Date (the “ Fundamental Change Repurchase Price ”); provided that if the relevant Fundamental Change Conversion Date is on a date that is after a Dividend Record Date and on or prior to the corresponding Dividend Payment Date, the Trust shall pay such dividends to the holder of record on the corresponding Dividend Record Date, and the Fundamental Change Repurchase Price per Series D Preferred Share shall be equal to the $25.00 liquidation preference of such Series D Preferred Share. The Repurchase Right shall be exercisable by notice from the Trust to holders of Series D Preferred Shares and to the Transfer Agent given not later than the time and in the manner provided in Section 10(e) and may be incorporated as a part of the notice delivered pursuant to such Section.

(c) In the event the Trust exercises the Repurchase Right with respect to Series D Preferred Shares that would otherwise be converted into Common Shares on a Fundamental Change Conversion Date, such Series D Preferred Shares shall not be converted into Common Shares, and the holder of such Series D Preferred Shares shall be entitled to receive the applicable Fundamental Change Repurchase Price in cash as provided in this Section 10.

If the number of Common Shares issuable upon such conversion would exceed 32,500,000 shares or such other number of Common Shares as shall then be authorized and available for issuance, the Trust shall have the option to satisfy the remainder of such conversion in common shares that are authorized for issuance in the future. The Trust shall use its best efforts to have any such additional number of Common Shares authorized for issuance within 180 days of the Fundamental Change Conversion Date.

(e) Within 15 Business Days after the occurrence of a Fundamental Change, the Trust shall mail to the Transfer Agent and all holders of Series D Preferred Shares, and to beneficial owners as required by applicable law, a notice regarding the Fundamental Change and of the resulting Repurchase Right.

The Trust shall issue a press release for publication to the Dow Jones & Company, Inc., Business Wire or Bloomberg Business News (or, if such organizations are not in existence at the time of issuance of such press release, such other news or press organization as is reasonably calculated to broadly disseminate the relevant information to the public) prior to the opening of business on the first Trading Day following any date on which the Trust provides such notice to the holders of Series D Preferred Shares. No failure of the Trust to give the foregoing notices and no defect therein shall limit the conversion rights of holders of Series D Preferred Shares or affect the validity of the proceedings for conversion or repurchase of the Series D Preferred Shares pursuant to this Section 10.

(f) In order to exercise the Fundamental Change Conversion Right a holder of Series D Preferred Shares must surrender to the Trust at its principal office or at the office of the Transfer Agent, as may be designated by the Board of Trustees, the certificate or certificates, if any, for the Series D Preferred Shares to be converted accompanied by a written notice specifying the name or names in which the holder wishes the certificate or certificates for the

- 28 -

converted on such date pursuant to the Fundamental Change Conversion Right and receipt of the notice in accordance with Section 10(f), and, if Common Shares to be issued upon conversion of such Series D Preferred Shares are to be registered in a name other than the name of the holder of such Series D Preferred Shares payment of all required transfer taxes, if any, or the demonstration to the Trust’s satisfaction that those taxes have been paid, unless the Trust shall have exercised the Repurchase Right with respect to such Series D Preferred Shares, (i) if Common Shares to be issued upon such conversion are certificated, the Trust shall issue and shall deliver or cause to be issued and delivered to such holder, or to such other Person on such holder’s written order (A) certificates evidencing the number of validly issued, fully paid and non-assessable full Common Shares to which the holder of the shares of Series D Preferred Shares being converted, or the holder’s transferee, shall be entitled, and (B) if less than the full number of such Series D Preferred Shares are being converted, if the Series D Preferred Shares are certificated, a new certificate or certificates, of like tenor, for the number of Series D Preferred Shares evidenced by the surrendered certificate or certificates, less the number of shares being converted (or otherwise the Trust shall cause the number of Series D Preferred Shares not being converted to remain registered in the name of such holder), or (ii) if Common Shares to be issued upon such conversion are not certificated, (A) the Trust shall cause the number of validly issued, fully paid and non-assessable full Common Shares to which a holder of shares of Series D Preferred Shares being converted, or a holder’s transferee, shall be entitled to be registered in the name of such holder or such transferee, as applicable, and (B) if less than the full number of such Series D Preferred Shares are being converted, if the Series D Preferred Shares are certificated, a new certificate or certificates, of like tenor, for the number of Series D Preferred Shares evidenced by the surrendered certificate or certificates, less the number of shares being converted (or otherwise the Trust shall cause the number of Series D Preferred Shares not being converted to remain registered in the name of such holder), and (C) if a fractional interest in respect of a Common Share arising upon such conversion is to be settled in cash as provided in Section 10(l), a check or other transfer of funds for the cash settlement amount.

(i) A conversion of Series D Preferred Shares pursuant to the Fundamental Change Conversion Right which has been properly exercised and for which the notice of exercise has not been withdrawn shall be deemed to have been made at the close of business on the Fundamental Change Conversion Date, unless the Repurchase Right has been exercised with respect to such Series D Preferred Shares, and at such time the rights of the holder thereof as to the Series D Preferred Shares being converted shall cease except for the right to receive Common Shares and, if applicable, cash in lieu of fractional Common Shares issuable upon such conversion, and the Person entitled to receive Common Shares shall be treated for all purposes as having become the record holder of those Common Shares at that time.

(j) If the Trust elected to repurchase Series D Preferred Shares subject to the exercise of a Fundamental Change Conversion Right, the Fundamental Change Conversion Right of the holder of such Series D Preferred Shares shall automatically not be exercisable, but the holder shall be entitled to receive the Fundamental Change Repurchase Price as provided below in this Section 10.

(k) The holder of any Series D Preferred Share which the Trust has elected to repurchase pursuant to the Repurchase Right and as to which the notice of exercise of the Fundamental Change Conversion right has not been properly withdrawn shall be entitled to payment of the Fundamental Change Repurchase Price from the Trust promptly following the later of (i) the Fundamental Change Conversion Date with respect to such Series D Preferred Shares and (ii) the time of book-entry transfer or delivery of such Series D Preferred Shares to the Transfer Agent. If the Transfer Agent holds cash sufficient to pay the Fundamental Change

- 29 -

(m) In case the notice of exercise of the Fundamental Change Conversion Right specifies that the Common Shares issuable upon conversion of Series D Preferred Shares are to be issued or registered in a name or names other than that of the registered holder of Series D Preferred Shares, the notice of exercise shall be accompanied by payment of all transfer taxes payable upon the issuance of Common Shares in that name or names. Other than those transfer taxes payable pursuant to the preceding sentence, the Trust shall pay any documentary, stamp or similar issue or transfer taxes that may be payable in respect of any issuance or delivery of Common Shares upon conversion of Series D Preferred Shares pursuant to the Fundamental Change Conversion Right.

(n) A holder of Series D Preferred Shares being converted pursuant to the Fundamental Change Conversion Right is not entitled to any rights of a holder of Common Shares, and only to the extent such Series D Preferred Shares have been or are deemed to have been converted to Common Shares in accordance with the provisions of this Section 10.

12.

Restrictions on Transfer .

(a) The Trustees, by notice to the holder thereof, may purchase any or all Series D Preferred Shares that have been transferred pursuant to a transfer or any or all Common Shares issued upon conversion of Preferred Shares which, in the opinion of the Trustees, would jeopardize the status of the Trust as a REIT for federal income tax purposes or, in the case of such Common Shares, result in such Common Share being Excess Shares under Section 6.14 of the Declaration. Without limiting the generality of the foregoing, as a condition to the transfer and/or registration of transfer of any Series D Preferred Shares (“ Excess Series D Preferred Shares ”) which could result in direct or indirect ownership (as defined in Section 6.14(i) of the Declaration) of Series D Preferred Shares representing more than 9.8% in value of the total Series D Preferred Shares outstanding becoming concentrated in the hands of one owner other than an Excepted Person (as such term is defined in Section 6.14(c) of the Declaration), such potential owner shall file with the Trust the statement or affidavit described in Section 6.14(b) of the Declaration no later than the fifteenth day prior to any transfer, registration of transfer or transaction which, if consummated, would result in such ownership. The Trustees shall have the power and right (i) by lot or other means deemed equitable by them to call for the purchase from the beneficial owner or the holder of such Excess Series D Preferred Shares or such Common Shares which are Excess Shares, and (ii) to refuse to transfer or issue Excess Series D Preferred Shares or such Common Shares which are Excess Shares or share certificates with respect thereto to any Person (as defined in Section 1.4(r) of the Declaration) whose acquisition of such Series D Preferred Shares or Common Shares would, in the opinion of the Trustees, result in the direct or indirect beneficial ownership of any Excess Series D Preferred Shares or Excess Shares by a person other than any of the Excepted Persons.

(b) Any Excess Series D Preferred Shares shall automatically be deemed to constitute Excess Shares (within the meaning of the Declaration) and shall be treated in the manner prescribed for Excess Shares, including, without limitation, the provisions set forth in Section 6.14(c) thereof.

(c) Notwithstanding any other provision of the Declaration or hereof to the contrary, any purported acquisition of Series D Preferred Shares (whether such purported acquisition results from the direct or indirect acquisition or ownership (as defined for purposes of the Declaration) of Series D Preferred Shares) or conversion of Series D Preferred Shares into Common Shares which would result in the disqualification of the Trust as a REIT for federal income tax purposes shall be null and void. Any such Series D Preferred Shares may be treated by the Trustees in the manner prescribed for Excess Series D Preferred Shares in these provisions of the Series D Preferred Shares and for Excess Shares in Section 6.14(c) of the Declaration, and any such Common Shares shall be Excess Shares in Section 6.14(c) of the Declaration.

(d) The provisions of this Section 12 shall not limit the applicability of Section 6.14 of the Declaration to Series D Preferred Shares or any Common Shares issued upon conversion thereof in accordance with the terms thereof, and the provisions of this Section 12 and of Section 6.14 of the Declaration shall not limit the right of the Trust to elect to redeem Excess Series D Preferred Shares pursuant to Section 5(b) hereof. Nothing contained in this Section 12 or in any other provision of the Series D Preferred Shares shall limit the authority of the Trustees

- 31 -

to take such other action as they deem necessary or advisable to protect the Trust and the interests of the shareholders by preservation of the Trust’s status as a REIT for federal income tax purposes. The provisions of subsections (g) through (i) of Section 6.14 of the Declaration shall be applicable to this Section 12 as though (i) the references therein to Section 6.14 of the Declaration referred instead to this Section 12 and (ii) the references therein to subsections of Section 6.14 of the Declaration referred to the comparable provisions of this Section 12.

13. Severability . If any preference, right, voting power, restriction, limitation as to dividends or other distributions, qualification, term or condition of redemption or other term of the Series D Preferred Shares is invalid, unlawful or incapable of being enforced by reason of any rule of law or public policy, then, to the extent permitted by law, all other preferences, rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications, terms and conditions of redemption and other terms of the Series D Preferred Shares which can be given effect without the invalid, unlawful or unenforceable preference, right, voting power, restriction, limitation as to dividends or other distributions, qualification, term or condition of redemption or other term of the Series D Preferred Shares shall remain in full force and effect and shall not be deemed dependent upon any invalid, unlawful or unenforceable preference, right, voting power, restriction, limitation as to dividends or other distributions, qualification, term or condition of redemption or other term of the Series D Preferred Shares.

14. Notices to Holders . Unless otherwise provided herein or required by law, notices to holders of Series D Preferred Shares provided for in these Articles Supplementary shall be mailed to such holders by first class mail, postage pre-paid, at the respective addresses as the same shall appear on the share transfer records of the Trust or the Transfer Agent.
