(a) To the maximum extent that Maryland law in effect from time to time permits limitation of the liability of directors and officers of a corporation, no Director or officer of the Corporation shall be liable to the Corporation or its Stockholders for money damages. Neither the amendment nor repeal of this Section 6.5(a), nor the adoption or amendment of any other provision of the Charter or Bylaws inconsistent with this Section 6.5(a), shall apply to or affect in any respect the applicability of the preceding sentence with respect to any act or failure to act which occurred prior to such amendment, repeal or adoption.

(b) To the maximum extent permitted by Maryland law in effect from time to time, the Corporation shall indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, shall pay or reimburse reasonable expenses in advance of final disposition of a proceeding to (a) any individual who is a present or former Director or officer of the Corporation and who is made or threatened to be made a party to, or witness in, the proceeding by reason of his or her service in that capacity or (b) any individual who, while a Director or officer of the Corporation and at the request of the Corporation, serves or has served as a director, officer, trustee, member, manager or partner of another corporation, real estate investment trust, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise and who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity. The rights to indemnification and advance of expenses provided by this Section 6.5 shall vest immediately upon election of a Director or officer. The Corporation may, with the approval of the Board of Directors, provide such indemnification and advance for expenses to an individual who served a predecessor of the Corporation in any of the capacities described in (a) or (b) above and to any employee or agent of the Corporation or a predecessor of the Corporation. The indemnification and payment or reimbursement of expenses provided in this Section 6.5 shall not be deemed exclusive of or limit in any way other rights to which any person seeking indemnification or payment or reimbursement of expenses may be or may become entitled under any bylaw, resolution, insurance, agreement or otherwise. Neither the amendment nor repeal of this Section 6.5(b), nor the adoption or amendment of any other provision of the Charter or Bylaws inconsistent with this Section 6.5(b), shall apply to or affect in any respect the applicability of this Section 6.5(b) with respect to any act or failure to act which occurred prior to such amendment, repeal or adoption.

The omission of the foregoing exculpatory language from any instrument shall not affect the validity or enforceability of such instrument and shall not render any Stockholder, Director, officer, employee or agent liable thereunder to any third party, nor shall the Directors or any officer, employee or agent of the Corporation be liable to anyone as a result of such omission.

Section 6.7 Extraordinary Actions. Notwithstanding any provision of law permitting or requiring any action to be taken or approved by the affirmative vote of the holders of Shares entitled to cast a greater number of votes, any such action shall be effective and valid if declared advisable by the Board of Directors and taken or approved by the affirmative vote of holders of Shares entitled to cast a majority of all the votes entitled to be cast on the matter.

Section 6.8 Authorization by Board of Stock Issuance. The Board of Directors 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 as the Board of Directors may deem advisable (or without consideration in the case of a stock split or stock dividend), subject to such restrictions or limitations, if any, as may be set forth in the Charter or the Bylaws.

Section 6.9 Preemptive Rights and Appraisal Rights. Except as may be provided by the Board of Directors in setting the terms of classified or reclassified Shares pursuant to Section 5.4 or as may otherwise be provided by contract approved by the Board of Directors, no holder of Shares shall, as such holder, have any preemptive right to purchase or subscribe for any additional Shares or any other security of the Corporation which it may issue or sell. Holders of Shares shall not be entitled to exercise any rights of an objecting stockholder provided for under Title 3, Subtitle 2 of the MGCL or any successor statute unless the Board of Directors, upon the affirmative vote of a majority of the Board of Directors, shall determine that such rights apply, with respect to all or any classes or series of stock, to one or more transactions occurring after the date of such determination in connection with which holders of such Shares would otherwise be entitled to exercise such rights.

Section 6.10 Tender Offers. If any Person makes a tender offer, including, without limitation, a “mini-tender” offer, such Person must comply with all of the provisions set forth in Regulation 14D of the Exchange Act, including, without limitation, disclosure and notice requirements, that would be applicable if the tender offer was for more than five percent of the outstanding Shares; provided, however, that, unless otherwise required by the Exchange Act, such documents are not required to be filed with the Securities and Exchange Commission. In addition, any such Person must provide notice to the Corporation at least ten business days prior to initiating any such tender offer. If any Person initiates a tender offer without complying with the provisions set forth above (a “Non-Compliant Tender Offer”), the Corporation, in its sole discretion, shall have the right to redeem such non-compliant Person’s Shares and any Shares acquired in such tender offer (collectively, the “Tendered Shares”) at the lesser of (i) the price then being paid per Common Share purchased in the Corporation’s latest Offering at full purchase price (not discounted for commission reductions or for reductions in sale price permitted pursuant to any Distribution reinvestment plan that the Board may establish), (ii) the fair market value of the Shares as determined by an independent valuation obtained by the Corporation or (iii) the lowest tender offer price offered in such Non-Compliant Tender Offer. The Corporation may purchase such Tendered Shares upon delivery of the purchase price to the Person initiating such Non-Compliant Tender Offer and, upon such delivery, the Corporation may instruct any transfer agent to transfer such purchased Shares to the Corporation. In addition, any Person who makes a Non-Compliant Tender Offer shall be responsible for all expenses incurred by the Corporation in connection with the enforcement of the provisions of this Section 6.10, including, without limitation, expenses incurred in connection with the review of all documents related to such tender offer and expenses incurred in connection with any purchase of Tendered Shares by the Corporation. The Corporation maintains the right to offset any such expenses against the dollar amount to be paid by the Corporation for the purchase of Tendered Shares pursuant to this Section 6.10. In addition to the remedies provided herein, the Corporation may seek injunctive relief, including, without limitation, a temporary or permanent restraining order, in connection with any Non-Compliant Tender Offer. This Section 6.10 shall be of no force or effect with respect to any Shares that are then Listed.
