Section 5.2.     Number; Initial Trustees; Classification; Qualifications .

Section  5.2.1.        The trustees of the Trust (hereinafter, the “Trustees”), and such other persons as the Trustee or Trustees then in office shall elect, shall serve until the first meeting of shareholders at which Trustees of his or her Class (as defined below) are elected and until his or her successor is duly elected and qualified, or until he or she sooner dies, resigns, retires, or is disqualified or removed from office.  Any person serving as Trustee shall meet the criteria and qualifications for office set forth from time to time in the Bylaws.  The Board of Trustees shall be comprised of Independent Trustees and Managing Trustees (as each term is defined in the Bylaws) in such number as set forth from time to time in the Bylaws.  The number of Trustees shall initially be five and, subject to the voting powers of one or more classes or series of Shares (as defined in Section 6.1 below) as set forth in the Bylaws, the number of Trustees shall be such number as shall be fixed from time to time by the Trustees; provided, however, that the number of Trustees shall in no event be less than three.  The names of the individuals who shall serve as initial Trustees are as follows:

Managing Trustees:

Section  5.2.2.        Annual meetings of Shareholders shall be held as specified in the Bylaws.  The Trustees shall be classified, with respect to the time for which they severally hold office, into the following three classes (each a “Class”): Class I, whose term expires at the initial annual meeting; Class II, whose term expires at the next succeeding annual meeting after the initial annual meeting (the “second annual meeting”); and Class III, whose term expires at the next succeeding annual meeting after the second annual meeting.  Each Class shall consist of at least one Trustee.  At each annual meeting beginning with the initial annual meeting, the successors of the Class of Trustees whose term expires at that meeting shall be elected to hold office for a term expiring at the annual meeting held in the third year following the year of their election, with each Trustee holding office until the expiration of the term of the relevant Class and the election and qualification of his or her successor, or until he or she sooner dies, resigns, retires, or is disqualified or removed from office.  The Trustees shall assign by resolution Trustees to each of the three Classes.  The Trustees also may determine by resolution those Trustees in each Class that shall be elected by shareholders of a particular class or series of Shares.  If the number of Trustees is changed, any increase or decrease shall be apportioned among the Classes by resolution of the Trustees.

Section  5.2.3.        Vacancies on the Board of Trustees, whether resulting from an increase in the number of Trustees or otherwise, shall be filled in the manner provided in the Bylaws.  It shall not be necessary to list in this Declaration of Trust the names and addresses of any Trustees hereinafter elected.  No reduction in the number of Trustees shall have the effect of removing any Trustee from office prior to the expiration of his or her term unless the Trustee is specifically removed pursuant to Section 5.3 at the time of the decrease.  Subject to the provisions of Section 5.3, each Trustee shall hold office until the election and qualification of his or her successor.  There shall be no cumulative voting in the election of Trustees.

Section 5.3.     Resignation or Removal .  Any Trustee may resign or retire as a Trustee by an instrument in writing signed by him and delivered to the secretary of the Trust, and such resignation or retirement shall be effective upon such delivery, or at a later date according to the terms of the instrument.  A Trustee judged incompetent or for whom a guardian or conservator has been appointed shall be deemed to have resigned as of the date of such adjudication or appointment.  A Trustee may be removed at any time (a) solely with cause, at a meeting of the shareholders properly called for that purpose, by the affirmative vote of the holders of not less than 75% of the Shares then outstanding and entitled to vote in the election of such Trustee or (b) with or without cause by the affirmative vote of not less than 75% of the remaining Trustees.

Section 5.4.     Determinations by Board .  The determination as to any of the following matters, made by or pursuant to the direction of the Board of Trustees consistent with this Declaration of Trust, shall be final and conclusive and shall be binding upon the Trust and every holder of Shares:  the amount of the net income of the Trust for any period and the amount of assets at any time legally available for the payment of dividends, redemption of Shares or the payment of other distributions on Shares; the amount of paid-in surplus, net assets, other surplus, annual or other cash flow, funds from operations, net profit, net assets in excess of capital, undivided profits or excess of profits over losses on sales of assets; the amount, purpose, time of creation, increase or decrease, alteration or cancellation of any reserves or charges and the propriety thereof (whether or not any obligation or liability for which such reserves or charges shall have been created shall have been paid or discharged); any interpretation of the terms, preferences, conversion or other rights, voting powers or rights, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption of any class or series of Shares; the fair value, or any sale, bid or asked price to be applied in determining the fair value, of any asset owned or held by the Trust or of any Shares; the number of Shares of any class of the Trust; any matter relating to the acquisition, holding and disposition of any assets by the Trust; or any other matter relating to the business and affairs of the Trust or required or permitted by applicable law, this Declaration of Trust or the Bylaws or otherwise to be determined by the Board of Trustees.

ARTICLE VI

SHARES OF BENEFICIAL INTEREST

Section 6.1.     Authorized Shares .  The beneficial interest of the Trust shall be divided into shares of beneficial interest (the “Shares”).  The Trust has authority to issue

50,000,000 Shares, consisting of 50,000,000 common shares of beneficial interest, $.01 par value per share (“Common Shares”).  If shares of one class are classified or reclassified into shares of another class of shares pursuant to this ARTICLE VI, the number of authorized shares of the former class shall be automatically decreased and the number of shares of the latter class shall be automatically increased, in each case by the number of shares so classified or reclassified, so that the aggregate number of shares of beneficial interest of all classes that the Trust has authority to issue shall not be more than the total number of shares of beneficial interest set forth in the second sentence of this paragraph.  The Board of Trustees, without any action by the shareholders of the Trust, may amend this Declaration of Trust from time to time to increase or decrease the aggregate number of Shares or the number of Shares of any class or series that the Trust has authority to issue.

Section 6.2.     Common Shares .  Subject to the provisions of ARTICLE VII, each Common Share shall entitle the holder thereof to one vote on each matter upon which holders of Common Shares are entitled to vote.  The Board of Trustees may reclassify any unissued Common Shares from time to time into one or more classes or series of Shares.

Section 6.3.     Classified or Reclassified Shares .  Prior to issuance of classified or reclassified Shares of any class or series, the Board of Trustees by resolution shall (a) designate that class or series; (b) specify the number of Shares to be included in the class or series; (c) set, subject to the provisions of ARTICLE VII, the preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms and conditions of redemption for each class or series; and (d) cause the Trust to file articles supplementary with the State Department of Assessments and Taxation of Maryland (the “SDAT”).  Any of the terms of any class or series of Shares set pursuant to clause (c) of this Section 6.3 may be made dependent upon facts ascertainable outside this Declaration of Trust (including the occurrence of any event, determination or action by the Trust or any other person or body) and may vary among holders thereof, provided that the manner in which such facts or variations shall operate upon the terms of such class or series of Shares is clearly and expressly set forth in the articles supplementary filed with the SDAT.

Section 6.4.     Authorization by Board of Share Issuance .  The Board of Trustees may authorize the issuance from time to time of Shares of any class or series, whether now or hereafter authorized, or securities or rights convertible into Shares of any class or series, whether now or hereafter authorized, for such consideration (whether in cash, property, past or future services, obligation for future payment or otherwise) as the Board of Trustees may deem advisable (or without consideration), subject to such restrictions or limitations, if any, as may be set forth in this Declaration of Trust or the Bylaws of the Trust.

Section 6.5.     Dividends and Distributions .  The Board of Trustees may from time to time authorize and declare to shareholders such dividends or distributions, in cash or other assets of the Trust or in securities of the Trust or from any other source as the Board of Trustees in its discretion shall determine.  Shareholders shall have no right to any dividend or distribution unless and until authorized and declared by the Board.  The exercise of the powers and rights of the Board of Trustees pursuant to this Section 6.5 shall be subject to the provisions of any class or series of Shares at the time outstanding.

Section 6.6.     General Nature of Shares .  All Shares shall be personal property entitling the shareholders only to those rights provided in this Declaration of Trust.  The shareholders shall have no interest in the property of the Trust and shall have no right to compel any partition, division, dividend or distribution of the Trust or of the property of the Trust.  The death of a shareholder shall not terminate the Trust or affect its continuity nor give his or her legal representative any rights whatsoever, whether against or in respect of other shareholders, the Trustees or the trust estate or otherwise, except the sole right to demand and, subject to the provisions of this Declaration of Trust, the Bylaws and any requirements of law, to receive a new certificate for Shares registered in the name of such legal representative, in exchange for the certificate held by such shareholder.  The Trust is entitled to treat as shareholders only those persons in whose names Shares are registered as holders of Shares on the beneficial interest ledger of the Trust.

Section 6.7.     Fractional Shares .  The Trust may, without the consent or approval of any shareholder, issue fractional Shares, eliminate a fraction of a Share by rounding up or down to a full Share, arrange for the disposition of a fraction of a Share by the person entitled to it or pay cash for the fair value of a fraction of a Share.

Section 6.8.     Declaration and Bylaws .  All shareholders are subject to the provisions of this Declaration of Trust and the Bylaws of the Trust.

Section 6.9.     Divisions and Combinations of Shares .  Subject to an express provision to the contrary in the terms of any class or series of beneficial interest hereafter authorized, the Board of Trustees shall have the power to divide, split or combine (by issuing or redeeming, as applicable, Shares pro rata or by any other lawful means) the outstanding shares of any class or series of beneficial interest, without a vote of shareholders.

Section 6.10.   Arbitration .

Section  6.10.1.      Any disputes, claims or controversies brought by or on behalf of any shareholder of the Trust (which, for purposes of this Section 6.10, shall mean any shareholder of record or any beneficial owner of Shares, or any former shareholder of record or beneficial owner of Shares), either on his, her or its own behalf, on behalf of the Trust or on behalf of any series or class of Shares or shareholders of the Trust against the Trust or any Trustee, officer, manager (including Reit Management & Research LLC or its successor), agent or employee of the Trust, including disputes, claims or controversies relating to the meaning, interpretation, effect, validity, performance or enforcement of this Declaration of Trust or the Bylaws (all of which are referred to as “Disputes”) or relating in any way to such a Dispute or Disputes, shall on the demand of any party to such Dispute be resolved through binding and final arbitration in accordance with the procedures and rules for arbitration prescribed by the Bylaws. For the avoidance of doubt, and not as a limitation, Disputes are intended to include derivative actions against Trustees, officers or managers of the Trust and class actions by shareholders against those individuals or entities and the Trust.  For the avoidance of doubt, a Dispute shall include a Dispute made derivatively on behalf of one party against another party.

Section  6.10.2.      The award or decision of the arbitrator(s) shall be final and binding upon the parties thereto and shall be the sole and exclusive remedy between such parties relating to the Dispute, including any claims, counterclaims, issues or accounting presented to the arbitrators.  Judgment upon the Award may be entered in any court having jurisdiction.  To the fullest extent permitted by law, no application or appeal to any court of competent jurisdiction may be made in connection with any question of law arising in the course of arbitration or with respect to any award made, except for actions relating to enforcement of this agreement to arbitrate or any arbitral award issued hereunder and except for actions seeking interim or other provisional relief in aid of arbitration proceedings in any court of competent jurisdiction.

Section  6.10.3.      Except as otherwise set forth in Section 8.6 or ARTICLE IX, the Bylaws or agreed between the parties, each party involved in a Dispute shall bear its own costs and expenses (including attorneys’ fees), and the arbitrators shall not render an award that would include shifting of any such costs or expenses (including attorneys’ fees) or, in a derivative case or class action, award any portion of the Trust’s award to the claimant or the claimant’s attorneys.

Section  6.10.4.      This Section 6.10 is intended to benefit and be enforceable by the Trustees, officers, managers (including Reit Management & Research LLC or its successor), agents or employees of the Trust and shall be binding on the shareholders of the Trust and the Trust, as applicable, and shall be in addition to, and not in substitution for, any other rights to indemnification or contribution that such individuals or entities may have by contract or otherwise.
