	3.	CROSS LICENSE OF PATENT APPLICATIONS AND ACQUIRED PATENTS 

  

	3.1	Subject to the terms and conditions of this Agreement, Cabot agrees to grant to Aspen as of the Effective Date a non-exclusive, worldwide license to practice any invention claimed in its Patent Applications and Acquired
Patents, only with respect to Aerogels and/or the Aspen Blanket manufactured using as its predominant means of drying (i.e. solvent removal), a step that uses a fluid which is at least [***]% (by volume) supercritical carbon dioxide, at a pressure

applications. This license may be sublicensed to any Affiliate of Cabot, so long as such entity remains an Affiliate of Cabot.

intellectual property right (including, without limitation, know-how and trade secrets) of either party. More specifically, in the event claims of an Issued Patent dominate an invention claimed in a Patent Application and Acquired Patent in a
particular jurisdiction, the practice of the invention in such Patent Application is restricted by a party’s Field of Use.

 7 

	 	(b)	Equity Payment 

  

	 	(i)	Aspen hereby grants Cabot a credit to be applied to an equity investment in Aspen of Sixteen Million Dollars ($16,000,000) (the “Equity Investment Credit”) for shares of convertible preferred stock of Aspen
upon terms and conditions outlined below. The value of the Equity Investment Credit shall be $16,000,000 based on an expectation by the Parties that the total post money value of Aspen after the Equity Closing (including such Equity Investment
Credit) (“Aspen’s Value”) will be not greater than $240 Million. In the event that Aspen’s Value is to exceed $240 Million at the Equity Closing, Cabot’s Equity Investment Credit shall be increased proportionately based on
the increase in Aspen’s Value at such time. 

  

	 	(ii)	In preparation of the Equity Closing, the Parties shall prepare and at the Equity Closing enter into a Share Purchase Agreement, a Stockholders’ Agreement and any other agreements necessary to enable Cabot to apply
its Equity Investment Credit for convertible preferred shares (the “Equity Series”) in Aspen. The Parties have agreed that the stock provided at the Equity Closing will contain all the same legal and economic rights and privileges for
Cabot as for the Lead Investor, except that in those certain cases set forth in Schedule B attached hereto where the Equity Series is entitled to vote on certain matters separately as a class, the requisite approval by the Equity Series will
be determined without reference to the shares held by Cabot, and Cabot will then vote its shares of the Equity Series in the same proportion as the other holders of such Series. Without limiting the foregoing, Cabot shall have no vote for any
representative on the board of directors of Aspen but will have the same registration rights granted to such Lead Investor, excluding the right to require an S-1 registration. In all other respects, Cabot shall have the same voting rights and
privileges as all other holders of the Equity Series. The Share Purchase Agreement shall provide that Cabot shall have no access to information regarding Aspen, in its capacity as a shareholder of or investor in Aspen, other than the annual audited
financial statements of Aspen commencing with those as of December 31, 2006 and the right to have informal discussions with the President of Aspen on a quarterly basis, during which no confidential or proprietary information of Aspen shall be
discussed. Said annual audited financial statements shall be furnished to Cabot promptly upon becoming available, but in any event within 10 business days of the date they are issued by Aspen’s auditors. Finally, the Parties agree that the
Share Purchase Agreement shall include an undertaking by Aspen to cause its legal counsel to deliver to Cabot at the Equity Closing a legal opinion in form and substance substantially identical to that opinion delivered to the other holders of the
convertible preferred securities of Aspen with respect to all matters, including, but not limited to due incorporation, authorization and issuance of shares, approvals and the like. 

 
 Portions of this Exhibit, indicated by the mark “[***],” were omitted and have
been filed separately with the Secretary of the Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 406 of the Securities Act of 1933, as amended. 

  
 8 

	 	(iii)	In the event that the Equity Closing does not occur within 120 days of the date of the execution of this Agreement or, the Equity Closing does not provide Cabot the ability to apply its Equity Investment Credit as
contemplated herein for whatever reason, Cabot may require Aspen to enter into all necessary agreements and obtain all necessary approvals required to apply Cabot’s Equity Investment Credit for shares of convertible preferred stock in Aspen
upon the following terms: 

  

	 	(1)	The investment shall be on terms no less favorable than those provided the Series D Preferred Shareholders, including their per share price, and shall provide Cabot rights and privileges equal to or superior to those
already existing for the Series D Preferred Shareholders. The Parties shall enter into a Share Purchase Agreement and a Stockholder’s Agreement and any other agreement necessary to effectuate application of the Equity Investment Credit as
provided for in this subsection. The Series D Preferred Stock issued to Cabot will contain all the same legal and economic rights and privileges for Cabot as for the lead investor in the original Series D round. Notwithstanding the foregoing, the
same rights and exceptions outlined in Section 4.1(b)(ii) shall apply to the foregoing agreements, and Cabot shall be furnished with an opinion of counsel as described above. 

 

	 	(2)	In addition, if, after the issuance of Series D Preferred Stock of Aspen to Cabot pursuant to this Section 4.1(b)(iii) but prior to a QPO, Aspen shall have an equity financing which meets the definition of
“Equity Closing” at a valuation lower than the implied post money valuation of Aspen under its original Series D financing round ($150,000,000), the conversion price of the Series D Preferred Stock issued to Cabot under this
Section 4.l(b)(iii) shall be reduced to give Cabot the same valuation as that received by the Lead Investor at said Equity Closing. In other words, Cabot shall have full ratchet anti dilution protection with respect to said equity financing
round. 

  

	 	(3)	The agreements identified in Section 4.1(b)(iii)(1) above shall provide for a closing to enable Cabot to apply its Equity Investment Credit as outlined above not later than six (6) months from the date of the
execution of this Agreement and, in any event, prior to any QPO. 

  

	 	(iv)	When Cabot acquires shares in Aspen in exchange for the Equity Investment Credit as outlined in paragraphs (ii) or (iii) above, Cabot agrees to provide Aspen with appropriate and customary representations and
warranties, including:

 9 

	 	(1)	That it would be acquiring such shares for investment for its own account, not as a nominee or agent, and not with the view to, or for resale in connection with, any distribution of any part thereof; 

 

	 	(2)	That it understands that such shares to be acquired have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or applicable state and other securities laws by reason of a
specific exemption from the registrations provisions of the Securities Act and applicable state and other securities laws, the availability of which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of
Cabot’s representations as expressed therein. 

  

	 	(3)	That it understands any transfer agent of Aspen shares will issue stop-transfer instructions with respect to such shares unless any transfer thereof is subsequently registered under the Securities Act and applicable
state and other securities laws or unless an exemption from such registration is available.

	6.1	Both Parties hereby agree that neither Party is now, nor will be in the future, obliged by virtue of this Agreement or any agreements contemplated to be entered into in furtherance of this Agreement, to furnish any
technical information or know-how to the other Party. 

  

	6.2	Both Parties hereby agree that they will act in good faith in carrying out the transactions contemplated in this Agreement and in particular, neither Party will use joint development of technology, transfer of Licensed
Intellectual Property ownership or licenses with third parties to circumvent the intent of this Agreement with respect to the agreements contained herein concerning intellectual property. 

 

	6.3	The Parties agree that the right to bring suit against infringers or alleged infringers of the Licensed Intellectual Property shall reside at all times solely with (a) Cabot, with respect to Cabot Issued Patents
and Cabot’s Patent Applications and Acquired Patents and (b) Aspen with respect to Aspen Issued Patents and Aspen’s Patent Applications and Acquired Patents. A party’s decision as to whether or not to bring suit against any

Portions of this Exhibit, indicated by the mark “[***],” were omitted and have been filed separately with the Secretary of the Commission pursuant to
the Registrant’s application requesting confidential treatment pursuant to Rule 406 of the Securities Act of 1933, as amended. 

  
 13 

	6.4	Nothing in this Agreement shall be construed as an admission by any party of infringement of any patent held by the other party. 

  

	6.5	Aspen hereby agrees to pay Cabot the same proportionate amount of any damages recovered or settlements it pays to any of the holders of the same class of convertible preferred securities of Aspen that Cabot acquires
pursuant to either Sections 4.l(b)(i) or (iii) above (the “Other Holders”) within 5 days of any payment made to the Other Holders for the breach of any material representation, warranty or certification made by Aspen in the Share
Purchase Agreement entered into by the Other Holders, or in any document delivered to the Other Holders in connection therewith. 

  

	6.6	Each Party agrees that it will not bring any legal challenge to the validity of any Licensed Intellectual Property so long as this Agreement shall not have been terminated in whole or in part. 

 

	7.	TERM AND TERMINATION 

  

	7.1	This Agreement shall become effective on the Effective Date, and unless sooner terminated as provided herein below, shall continue until the expiration of the last to expire of the Issued Patents or Patent Applications
and Acquired Patents licensed hereunder, at which time it shall expire. Any termination or expiration of this Agreement shall not affect any obligations on the part of Aspen to pay any of the consideration set forth in Article 4 to Cabot, except
that such payment obligations shall terminate (a) where on account of an Event of Default by Cabot, Aspen either terminates the licenses it has granted hereunder to Cabot or terminates this Agreement in its entirety, or (b) if Cabot should
terminate the Agreement on account of an Event of Default described in Section 1.11(f). 

  

	7.2	Upon the occurrence of an Event of Default by either Party (as defined in Section 1.11 above) the non-defaulting Party shall have the right to terminate this Agreement in whole or in part, as provided for in this
Section, provided such Party has given the defaulting Party (a) written notice detailing the default (the “Default Notice”) and (b) a 30 day cure period to remedy the default (the “Cure Period”) which shall run as from
the date of delivery of the Default Notice. Within 60 days of the expiration of the Cure Period the non-defaulting Party shall provide written notice to the defaulting Party of its election to terminate this Agreement in its entirety or to partially
terminate the Agreement by terminating all of the licenses it has granted under this Agreement to the defaulting Party (“Partial Termination”). In the case of Partial Termination the non-defaulting party shall continue to hold the licenses
granted by the defaulting Party under this Agreement and the defaulting Party shall continue to be obligated to comply with the provisions of this Cross License Agreement with respect thereto. Any termination of this Agreement pursuant to this
Section shall be in addition to, and shall not be exclusive of or prejudicial to, any rights or remedies said non-defaulting party may have on account of any default hereunder, including, but not limited to the non-defaulting party’s right to
proceed to protect its rights by suit in equity, action at law and/or other appropriate proceeding either for specific performance of any covenant or condition contained in this Agreement.

 14 

 Without limiting the foregoing, should Cabot terminate this Agreement on account of an Event of
Default described in Sections 1.11(d) or (e), Cabot shall have the right, irrespective of whether any cash payments have been made to Cabot pursuant to Paragraph 4.1(a), to (a) revoke, effective as of the earlier of the date of grant or
publication of its pertinent Issued Patents, any licenses granted herein and (b) commence against Aspen any suit, action or proceeding of any kind based upon assertion of infringement of any Issued Patent. 

Notwithstanding the foregoing, should Cabot terminate this Agreement on account of an Event of Default described in Section 1.11(f), such
termination must be a termination of this Agreement in its entirety, and Cabot shall return to Aspen, without consideration, any and all equity securities of Aspen it may have received from Aspen, and such securities shall be deemed cancelled as of
the date of such termination. 
  

	8.	CONFIDENTIALITY AND PUBLIC ANNOUNCEMENTS 

  

	8.1	Except as required by applicable laws, the Parties agree to maintain the economic terms of this Agreement in confidence and shall not disclose to any third party other than their respective board of directors,
investors, bankers or other similar parties who have a need to know except with prior written approval of the other Party. 

  

	8.2	Neither Party shall issue any press release or make any such public statement relating to the subject matter of this Agreement prior to consultation with and securing written approval of the other Party. Upon request by
any regulatory or administrative body or court of law for information relating to this Agreement, each Party agrees to notify the other of such request and upon providing any such information request confidential treatment of such information by the
requesting regulatory or administrative body or court of law. 

  

	9.	ASSIGNMENT 

  

	9.1	Neither this Agreement nor any interest herein may be assigned, in whole or in part, by either Party without the prior written consent of the other Party, which consent shall not be unreasonably withheld, except that
either Party may assign its rights and obligations to (a) any Affiliate of an assigning Party, provided however, that such assignment shall not relieve the assigning Party of its performance obligations under this Agreement, or (b) to a
successor entity in a Change of Control transaction, provided the successor entity agrees in writing to be bound by all of the terms of this Agreement. Notwithstanding the foregoing, no assignment may be made by any trustee or representative of
either Party in any bankruptcy or insolvency proceeding without the prior written consent of the non-assigning Party. Any purported assignment in contravention of the above shall be void.

	10.	APPLICABLE LAW AND DISPUTE RESOLUTION

matter to the laws of any other jurisdiction.

	11.	NOTICE 

  

	11.1	It shall be sufficient giving of any notice, request or other communication in writing under this Agreement by a Party to this Agreement to the other Party if the Party desiring to give such notice, request or other

	12.	FORCE MAJEURE 

  

	12.1	Neither Party shall be liable or penalized for its failure to perform any act or provide any right which it is obligated to perform or provide hereunder due to contingencies beyond its reasonable control (a “Force
Majeure Event”), including but not limited to: acts of God, fires, floods, wars, sabotage, terrorism, accidents, epidemics, quarantine, labor disputes or shortages of manpower, governmental laws, judgments, ordinances, rules and regulations,

	13.1	The failure of a party hereto at any time to exercise any of its rights or options under this Agreement, except rights and options specifically limited as to a date or time of exercise thereof, shall not be construed to

	14.	SEVERABILITY 

  

	14.1	Should any of the terms of this Agreement be or become fully or partly invalid, the legal validity of the Agreement shall not be affected thereby. This applies also to any possible omission which may be found in the
Agreement. In such cases, this Agreement shall be supplemented by a provision which, as far as is legally possible, comes nearest to what both parties hereto had desired or would have desired according to the sense and purpose of the Agreement, if
they had considered the point when concluding the Agreement.

This Settlement Agreement and First Amendment to Cross License Agreement (hereinafter referred to as the “Settlement Agreement”) is

Aerogels, Inc., a Delaware corporation whose principal place of business is located at 30 Forbes Road, Building B, Northborough, Massachusetts 01532 (“Aspen”). 

WHEREAS, effective April 1, 2006, the Parties made and entered into a written Cross License Agreement (hereinafter referred to as the
“CLA”), pursuant to which Cabot and Aspen resolved certain actual or potential disputes concerning their respective intellectual property rights involving the manufacture and use of Aerogels by agreeing to license to one another their
related patents, pending and future patent applications, and patents granted thereon (collectively defined in Section 1.16 of the CLA, and hereinafter referred to in this Settlement Agreement, as the “Licensed Intellectual Property”),
in consideration of the various payments and other consideration set forth in the CLA; and 
 WHEREAS, on or about December 20, 2006,
Cabot delivered to Aspen a Notice of Default (hereinafter referred to as the “Notice of Default”) alleging, inter alia, that Aspen’s failure to make the Equity Payment to Cabot called for in Section 4.1(b) of the CLA
constituted an Event of Default under the terms of the CLA (hereinafter referred to as the “Event of Default”), and that, if Aspen failed to cure the Event of Default within thirty (30) days of delivery of Cabot’s Notice of
Default, Cabot reserved the right to terminate the CLA, in whole or in part, in accordance with its terms; and 
 WHEREAS, on or about
February 23, 2007, Cabot delivered to Aspen a Notice of Partial 

 Termination of Cross License Agreement (hereinafter referred to as the “Notice of Partial Termination”)
alleging, inter alia, that Cabot was terminating any and all licenses that Aspen had or may have had to the Cabot Issued Patents or the Cabot Patent Applications and Acquired Patents based upon Aspen’s failure to cure the Event of
Default, in accordance with the terms of the CLA; and 
 WHEREAS, on or about January 17, 2007, Aspen commenced an action against Cabot
in the Court of Chancery of the State of Delaware in and for New Castle County captioned Aspen Aerogels, Inc. v. Cabot Corporation, Civil Action No. 2675-N) (hereinafter referred to as the “Delaware Action”), asserting various
claims concerning the CLA and the subject matter thereof; and 
 WHEREAS, on or about January 21, 2007, Aspen filed its First Amended
Verified Complaint for Declaratory and Injunctive Relief in the Delaware Action asserting additional claims concerning the CLA and the subject matter thereof; and 

WHEREAS, on or about March 26, 2007, Cabot filed its Answer to Aspen’s First Amended Verified Complaint and Counterclaims asserting
various claims concerning the CLA and the subject matter thereof; and 
 WHEREAS, as reflected in the Delaware Action and otherwise, Cabot
and Aspen have multiple actual or potential disagreements and disputes regarding, inter alia, their respective compliance with the terms of the CLA, the existence and legal effect of the Event of Default, the validity of the Notice of
Default, the validity and enforceability of the Notice of Partial Termination, and the validity and enforceability of the Licensed Intellectual Property; and

discovery concerning their various claims, counterclaims and actual or potential defenses in that Action including, inter alia, their respective compliance with the terms of the CLA, the existence and legal effect of the Event of Default, the
validity of the Notice of Default, the validity and enforceability of the Notice of Partial Termination, and the validity and enforceability of the Licensed Intellectual Property; and 

WHEREAS Cabot and Aspen now desire to settle and resolve completely and forever any and all actual or threatened disagreements and disputes
between themselves arising out of, related to, or connected in any way with the CLA, the Delaware Action, the Event of Default, the Notice of Default, the Notice of Partial Termination, or certain of the Licensed Intellectual Property;

 Aspen shall make each of the foregoing payments to Cabot in United States currency on or before the scheduled due date,
provided, however, that Cabot acknowledges that the three (3) payments due on or before September 1, 2007 (in the total amount of $2,400,000) already have been timely paid in full by Aspen.” 

“4.2 In the event of a Change of Control of Aspen, all remaining Type A Payments set forth in Section 4.1 shall become immediately

acceleration, shall bear interest from the fourth (4th) business day after the date due until paid at the rate of 14% per annum (computed on the basis of a 360-day year consisting of twelve 30-day months),

further amounts as shall be sufficient to cover all costs and expenses incurred by Cabot in any enforcement or collection of Aspen’s payment obligations under this Article 4, including, without limitation, reasonable attorneys’ fees,

 “This Agreement shall become effective on the Effective Date and shall continue until the
expiration of the last to expire of the Issued Patents or Patent Applications and Acquired Patents licensed hereunder, at which time it shall expire. If (a) Aspen shall fail to make any payment to Cabot when due in accordance with
Section 4.1 and Aspen shall not make such payment (with interest if applicable under Section 4.3) within thirty (30) days after Cabot has given Aspen written notice of such failure, or (b) in accordance with Section 4.3
Cabot shall accelerate the due dates for any payments under Section 4.1 and Aspen shall thereafter fail to pay to Cabot within thirty (30) days after such acceleration all amounts then due to Cabot under Article 4 (i.e. the overdue
payments giving rise to such acceleration, the payments accelerated, and any interest due thereon), then in either such case, Cabot may, at its option, at any time or times thereafter while any amounts then due under Article 4 remain unpaid,
terminate all licenses to Aspen hereunder in their entirety, or may partially terminate the licenses to Aspen hereunder (a) by restricting the licenses to Aspen to specific Cabot Issued Patents, Patent Applications and Acquired Patents, or
specific claims thereunder, (b) by reducing the Aspen Field of Use, and (c) in any other manner that narrows the scope of the licenses to Aspen. The notice of termination issued by Cabot shall either state that it is a termination of all
licenses to Aspen hereunder, or shall specify the scope of the license remaining to Aspen hereunder. Any such termination by Cabot, whether of all licenses granted to Aspen or a partial termination as described above, shall not affect either the
licenses granted by Aspen to Cabot hereunder, which shall continue in full force and effect for the remainder of the term of this Agreement, or Cabot’s right to receive payment in accordance with Article 4 of all amounts provided for therein.
For the avoidance of doubt, if Cabot exercises its right to partially terminate the licenses granted to Aspen hereunder, Cabot shall continue to have the right at anytime thereafter while amounts then due to Cabot under Article 4 remain unpaid, by
supplemental notice of termination to terminate all licenses granted to Aspen hereunder, or to further narrow the scope of the licenses remaining to Aspen hereunder.” 

“Notwithstanding the foregoing if Cabot terminates the licenses to Aspen hereunder, in their entirety or partially, and if Aspen notifies
Cabot within ten (10) days following any such termination that it is engaged in a process to sell Aspen or its assets, and if within ninety (90) days following any such termination such sale shall actually be completed and Cabot shall
receive the full amount of all unpaid Type A and Type B payments (whether or not then due and payable) described in Section 4.1, and all interest accrued under Section 4.3, then any such default by Aspen shall be deemed cured, ab
initio, and all licenses to Aspen hereunder shall be retroactively reinstated and shall remain in full force and effect for the remainder of the term of this Agreement.”

agrees not to sell, transfer, pledge or mortgage its respective Issued Patents or its Patent Applications and Acquired Patents except by an instrument that expressly recognizes that such sale, transfer, pledge or mortgage is subject to the licenses
granted hereunder.” 
 (7) Section 10.2 is amended in its entirety to read as follows: 

“10.2 Other than in a case involving a failure to make a payment under Article 4, the Parties shall endeavor to settle any dispute arising
in connection with the interpretation or performance of, or otherwise in connection with this Agreement, through mutual consultation and negotiation. If no settlement can be reached through consultations of senior corporate management of the Parties
within thirty (30) days of one Party delivering a written notice of dispute to the other Party, then such matter may be finally settled by a court of competent jurisdiction.”

 CORPORATION AND OF THE STOCKHOLDERS AND DIRECTORS 

Section 4.1 Number of Directors. The business and affairs of the Corporation shall be managed under the direction of the Board of
Directors. The number of directors of the Corporation initially shall be two (2), which number may be increased or decreased only by the Board of Directors pursuant to the Bylaws, but shall never be less than the minimum number required by the
Maryland General Corporation Law (the “MGCL”). The names of the directors who shall serve until the first annual meeting of stockholders and until their successors are duly elected and qualify are:

 These directors may increase the number of directors and may fill any vacancy,
whether resulting from an increase in the number of directors or otherwise, on the Board of Directors occurring before the first annual meeting of stockholders in the manner provided in the Bylaws. 

The Corporation elects, at such time as it becomes eligible to make the election provided for under Section 3-802(b) of the MGCL, that,
except as may be provided by the Board of Directors in setting the terms of any class or series of stock, any and all vacancies on the Board of Directors may be filled only by the affirmative vote of a majority of the remaining directors in office,
even if the remaining directors do not constitute a quorum, and any director elected to fill a vacancy shall serve for the remainder of the full term of the directorship in which such vacancy occurred. 

  
 2 

 Section 4.2 Extraordinary Actions. Except as specifically provided in Section 4.8
(relating to removal of directors) and in Article VII (relating to amendments and transactions outside the ordinary course of business), 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 4.3 Authorization by Board of
Stock Issuance. The Board of Directors may authorize the issuance from time to time of shares of stock of the Corporation of any class or series, whether now or hereafter authorized, or securities or rights convertible into shares of its stock
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 4.4 Preemptive Rights. Except as may be provided by
the Board of Directors in setting the terms of classified or reclassified shares of stock pursuant to Section 5.4 or as may otherwise be provided by contract, no holder of shares of stock of the Corporation shall, as such holder, have any preemptive
right to purchase or subscribe for any additional shares of stock of the Corporation or any other security of the Corporation which it may issue or sell. 
 Section 4.5 Indemnification. The Corporation shall have the power, to the maximum extent permitted by Maryland law in effect from time to time, to obligate itself to indemnify, and to 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 

  
 3 

 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, partner or trustee of another corporation, real estate investment trust,
partnership, joint venture, trust, employee benefit plan or any other enterprise from and against any claim or liability to which such person may become subject or which such person may incur by reason of his or her service in such capacity. The
Corporation shall have the power, with the approval of the Board of Directors, to provide such indemnification and advancement of expenses to a person 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. 
 Section 4.6 Determinations by
Board. The determination as to any of the following matters, made in good faith by or pursuant to the direction of the Board of Directors consistent with the charter and in the absence of actual receipt of an improper benefit in money, property
or services or active and deliberate dishonesty established by a court, shall be final and conclusive and shall be binding upon the Corporation and every holder of shares of its stock: the amount of the net income of the Corporation for any period
and the amount of assets at any time legally available for the payment of dividends, redemption of its stock or the payment of other distributions on its stock; 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 stock of the 

  
 4 

 Corporation; 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 Corporation; the number of shares of stock of any class of the Corporation; any matter relating to the acquisition, holding and disposition of any assets by the Corporation; or any other matter relating to the business
and affairs of the Corporation or required or permitted by applicable law, the charter or Bylaws or otherwise to be determined by the Board of Directors. 
 Section 4.7 REIT Qualification. If the Corporation elects to qualify for federal income tax treatment as a REIT, the Board of Directors shall use its commercially reasonable efforts to take such
actions as are necessary or appropriate to preserve the status of the Corporation as a REIT; however, if the Board of Directors determines that it is no longer in the best interests of the Corporation to continue to be qualified as a REIT, the Board
of Directors may revoke or otherwise terminate the Corporation’s REIT election. 
 Section 4.8 Removal of
Directors. Subject to the rights of holders of one or more classes or series of Preferred Stock to elect or remove one or more directors, any director, or the entire Board of Directors, may be removed from office at any time, but only for cause
and then only by the affirmative vote of at least two thirds of the votes entitled to be cast generally in the election of directors. For the purpose of this paragraph, “cause” shall mean, with respect to any particular director,
conviction of a felony or a final judgment of a court of competent jurisdiction holding that such director caused demonstrable, material harm to the Corporation through bad faith or active and deliberate dishonesty. 

Section 4.9 Rights of Objecting Stockholders. Holders of shares of stock of the Corporation 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

  
 5 

 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 of stock of the Corporation would otherwise be entitled to exercise such rights. 
 ARTICLE V

or indirectly through one or more partnerships or limited liability companies) from such tenant would cause the Corporation to fail to satisfy any of the gross income requirements of Section 856(c) of the Code). 

6.2.2 If, during the period commencing on the Initial Date and prior to the Restriction Termination Date, any Transfer occurs that, if
effective, would result in any Person Beneficially or Constructively Owning Capital Stock in violation of Section 6.2.1 of 

  
 12 

 this Article VI, (i) then that number of shares of Capital Stock that otherwise would cause such Person to

6.2.3 Subject to Section 6.12 of this Article VI and notwithstanding any other provisions contained herein, during the period commencing

 6.2.4 It is expressly intended that the restrictions on ownership and Transfer described in this Section 6.2 of Article VI shall apply to restrict the rights of any members or partners in limited

 Section
6.3 Transfers of Common Stock in Trust. 
 6.3.1 Upon any purported Transfer or other event described in Section 6.2.2 of
this Article VI that would result in a transfer of shares of Capital Stock to a 

  
 13 

 Trust, such Capital Stock shall be deemed to have been transferred to the Trustee in his capacity as trustee
of a Trust for the exclusive benefit of one or more Charitable Beneficiaries. Such transfer to the Trustee shall be deemed to be effective as of the close of business on the business day prior to the purported Transfer or other event that results in
a transfer to the Trust pursuant to Section 6.2.2. The Trustee shall be appointed by the Corporation and shall be a Person unaffiliated with the Corporation, any Purported Beneficial Transferee and any Purported Record Transferee. Each Charitable
Beneficiary shall be designated by the Corporation as provided in Section 6.3.6 of this Article VI. 
 6.3.2 Capital Stock held
by the Trustee shall be issued and outstanding Capital Stock of the Corporation. The Purported Beneficial Transferee or Purported Record Transferee shall have no rights in the shares of Capital Stock held by the Trustee. The Purported Beneficial
Transferee or Purported Record Transferee shall not benefit economically from ownership of any shares held in trust by the Trustee, shall have no rights to dividends or other distributions and shall not possess any rights to vote or other rights
attributable to the shares of Capital Stock held in the Trust. 
 6.3.3 The Trustee shall have all voting rights and rights to
dividends or other distributions with respect to Capital Stock held in the Trust, which rights shall be exercised for the exclusive benefit of the Charitable Beneficiary. Any dividend or other distribution paid prior to the discovery by the
Corporation that shares of Capital Stock have been transferred to the Trustee shall be paid to the Trustee upon demand, and any dividend or other distribution declared or authorized but unpaid with respect to such Capital Stock shall be paid when
due to the Trustee. Any dividends or distributions so paid over to the Trustee shall be held in trust for the Charitable Beneficiary. The Purported Record Transferee and Purported Beneficial Transferee shall have no voting rights with respect to the
Capital Stock held in the 

  
 14 

 Trust and, subject to Maryland law, effective as of the date the Capital Stock has been transferred to the
Trustee, the Trustee shall have the authority (at the Trustee’s sole discretion) (i) to rescind as void any vote cast by a Purported Record Transferee with respect to such Capital Stock prior to the discovery by the Corporation that the Capital
Stock has been transferred to the Trustee and (ii) to recast such vote in accordance with the desires of the Trustee acting for the benefit of the Charitable Beneficiary; provided, however, that if the Corporation has already taken irreversible
corporate action, then the Trustee shall not have the authority to rescind and recast such vote. Notwithstanding the provisions of this Article VI, until the Corporation has received notification that the Capital Stock has been transferred into a
Trust, the Corporation shall be entitled to rely on its share transfer and other stockholder records for purposes of preparing lists of stockholders entitled to vote at meetings, determining the validity and authority of proxies and otherwise
conducting votes of stockholders. 
 6.3.4 Within 20 days of receiving notice from the Corporation that shares of Capital Stock
have been transferred to the Trust, the Trustee of the Trust shall sell the shares of Capital Stock held in the Trust to a person, designated by the Trustee, whose ownership of the shares of Capital Stock will not violate the ownership limitations
set forth in Section 6.2.1. Upon such sale, the interest of the Charitable Beneficiary in the shares of Capital Stock sold shall terminate and the Trustee shall distribute the net proceeds of the sale to the Purported Record Transferee and to the
Charitable Beneficiary as provided in this Section 6.3.4. The Purported Record Transferee shall receive the lesser of (i) the price paid by the Purported Record Transferee for the shares of Capital Stock in the transaction that resulted in such
transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Capital Stock at Market Price, the Market Price of such shares of Capital Stock on the day of the event which resulted
in the transfer of such shares of Capital Stock to the Trust) 

  
 15 

 and (ii) the price per share received by the Trustee (net of any commissions and other expenses of sale)
from the sale or other disposition of the shares of Capital Stock held in the Trust. The Trustee may reduce the amount payable to the Purported Record Transferee by the amount of dividends and distributions which have been paid to the Purported
Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 6.3.3 of this Article VI. Any net sales proceeds in excess of the amount payable to the Purported Record Transferee shall be immediately paid to the
Charitable Beneficiary together with any dividends or other distributions thereon. If, prior to the discovery by the Corporation that shares of such Capital Stock have been transferred to the Trustee, such shares of Capital Stock are sold by a
Purported Record Transferee then (x) such shares of Capital Stock shall be deemed to have been sold on behalf of the Trust and (y) to the extent that the Purported Record Transferee received an amount for such shares of Capital Stock that exceeds
the amount that such Purported Record Transferee was entitled to receive pursuant to this Section 6.3.4, such excess shall be paid to the Trustee upon demand. 
 6.3.5 Capital Stock transferred to the Trustee shall be deemed to have been offered for sale to the Corporation, or its designee, at a price per share equal to the lesser of (i) the price paid by the
Purported Record Transferee for the shares of Capital Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Capital Stock at
Market Price, the Market Price of such shares of Capital Stock on the day of the event which resulted in the transfer of such shares of Capital Stock to the Trust) and (ii) the Market Price on the date the Corporation, or its designee, accepts such
offer. The Corporation may reduce the amount payable to the Purported Record Transferee by the amount of dividends and distributions which has been paid to the Purported Record Transferee and are owed by the Purported Record 

  
 16 

 Transferee to the Trustee pursuant to Section 6.3.3 of this Article VI. The Corporation will pay the amount
of such reduction to the Trustee for the benefit of the Charitable Beneficiary. The Corporation shall have the right to accept such offer until the Trustee has sold the shares of Capital Stock held in the Trust pursuant to Section 6.3.4. Upon such a
sale to the Corporation, the interest of the Charitable Beneficiary in the shares of Capital Stock sold shall terminate and the Trustee shall distribute the net proceeds of the sale to the Purported Record Transferee, and any dividends or other
distributions held by Trustee with respect to such Capital Stock shall thereupon be paid to the Charitable Beneficiary. 

6.3.6 By written notice to the Trustee, the Corporation shall designate one or more nonprofit organizations to be the Charitable
Beneficiary of the interest in the Trust such that (i) the shares of Capital Stock held in the Trust would not violate the restrictions set forth in Section 6.2.1 in the hands of such Charitable Beneficiary and (ii) each Charitable Beneficiary is an
organization described in Sections 170(b)(1)(A), 170(c)(2) and 501(c)(3) of the Code. 
 Section 6.4 Remedies For Breach.
If the Board of Directors or a committee thereof or other designees if permitted by the MGCL shall at any time determine in good faith that a Transfer or other event has taken place in violation of Section 6.2 of this Article VI or that a Person
intends to acquire, has attempted to acquire or may acquire beneficial ownership (determined without reference to any rules of attribution), Beneficial Ownership or Constructive Ownership of any shares of the Corporation in violation of Section 6.2
of this Article VI (whether or not such violation is intended), the Board of Directors or a committee thereof or other designees if permitted by the MGCL shall take such action as it deems or they deem advisable to refuse to give effect or to
prevent such Transfer, including, but not limited to, causing the Corporation to redeem shares of Capital Stock, refusing to give effect to such 

  
 17 

 Transfer on the books of the Corporation or instituting proceedings to enjoin such Transfer or other event;
provided, however, that any Transfers (or, in the case of events other than a Transfer, ownership or Constructive Ownership or Beneficial Ownership) in violation of Section 6.2.1 of this Article VI shall automatically result in the transfer to a
Trust as described in Section 6.2.2 and any Transfer in violation of Section 6.2.3 shall, subject to Section 6.12, automatically be void ab initio irrespective of any action (or non-action) by the Board of Directors or a committee thereof.

 Section 6.5 Notice of Restricted Transfer. Any Person who acquires or attempts or intends to acquire shares in
violation of Section 6.2 of this Article VI, or any Person who is a Purported Beneficial Transferee such that an automatic transfer to a Trust results under Section 6.2.2 of this Article VI, shall immediately give written notice to the Corporation
of such event or, in the case of such a proposed or attempted transaction, give at least 15 days prior written notice and shall provide to the Corporation such other information as the Corporation may request in order to determine the effect, if
any, of such Transfer or attempted Transfer on the Corporation’s status as a REIT. 
 Section 6.6 Owners Required to
Provide Information. From the Initial Date and prior to the Restriction Termination Date, each Person who is a beneficial owner or Beneficial Owner or Constructive Owner of shares of Capital Stock and each Person (including the stockholder of
record) who is holding shares of Capital Stock for a beneficial owner or Beneficial Owner or Constructive Owner shall, on demand, provide to the Corporation a completed questionnaire containing the information regarding their ownership of such
shares, as set forth in the regulations (as in effect from time to time) of the U.S. Department of Treasury under the Code. In addition, each Person who is a beneficial owner or Beneficial Owner or Constructive Owner of shares of Capital Stock and
each Person (including the stockholder of 

  
 18 

 record) who is holding shares of Capital Stock for a beneficial owner or Beneficial Owner or Constructive
Owner shall, on demand, be required to disclose to the Corporation in writing such information as the Corporation may request in order to determine the effect, if any, of such stockholder’s Beneficial Ownership and Constructive Ownership of
shares of Capital Stock on the Corporation’s status as a REIT and to ensure compliance with the Aggregate Stock Ownership Limit, the Common Stock Ownership Limit, any other ownership limit or as otherwise permitted by the Board of Directors.

 Section 6.7 Remedies Not Limited. Nothing contained in this Article VI (but subject to Section 6.12 of this Article
VI) shall limit the authority of the Board of Directors to take such other action as it deems necessary or advisable to protect the Corporation and the interests of its stockholders by preservation of the Corporation’s status as a REIT.

 Section 6.8 Ambiguity. In the case of an ambiguity in the application of any of the provisions of this Article VI,
including any definition contained in Section 6.1, the Board of Directors shall have the power to determine the application of the provisions of this Article VI with respect to any situation based on the facts known to it (subject, however, to the
provisions of Section 6.12 of this Article VI). In the event Article VI requires an action by the Board of Directors and the charter of the Corporation does not provide specific guidance with respect to such action, the Board of Directors shall have
the power to determine the action to be taken so long as such action is not contrary to the provisions of Article VI. Absent a decision to the contrary by the Board of Directors (which the Board may make in its sole and absolute discretion), if a
Person would have (but for the remedies set forth in Section 6.2.2) acquired Beneficial or Constructive Ownership of Common Stock in violation of Section 6.2.1, such remedies (as applicable) shall apply first to the shares of Capital Stock which,
but for such remedies, would have been actually owned by such Person, and second to shares of Capital 

  
 19 

 Stock which, but for such remedies, would have been Beneficially Owned or Constructively Owned (but not
actually owned) by such Person, pro rata among the Persons who actually own such shares of Capital Stock based upon the relative number of the shares of Capital Stock held by each such Person. 

Section 6.9 Exceptions. 
 6.9.1 Subject to Section 6.2.1(c) of this Article VI, the Board of Directors, in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Beneficially
Owning shares of Capital Stock in excess of the Aggregate Stock Ownership Limit or Common Stock in excess of the Common Stock Ownership Limit, as set forth in Section 6.2.1(a) of this Article VI, if the Board determines that such exemption will not
cause any Individual’s Beneficial Ownership of shares of Capital Stock to violate the Capital Stock Ownership Limit and that any such exemption will not cause the Corporation to fail to qualify as a REIT under the Code. 

6.9.2 Subject to Section 6.2.1(c) of this Article VI, the Board of Directors, in its sole discretion, may exempt (prospectively or
retroactively) a Person from the limitation on a Person Constructively Owning Capital Stock in excess of the Aggregate Stock Ownership Limit or Common Stock in excess of the Common Stock Ownership Limit, as set forth in Section 6.2.1(b) of this
Article VI, if the Board determines that such Person does not and will not own, actually or Constructively, an interest in a tenant of the Corporation (or a tenant of any entity owned in whole or in part by the Corporation) that would cause the
Corporation to own, actually or Constructively, more than a 9.8% interest (as set forth in Section 856(d)(2)(B) of the Code) in such tenant or that any such ownership would not cause the Corporation to fail to qualify as a REIT under the Code.

  
 20 

 6.9.3 Subject to Section 6.2.1(c) and the remainder of this Section 6.9.3, the Board of
Directors may from time to time increase the Aggregate Stock Ownership Limit and/or the Common Stock Ownership Limit for one or more Persons and decrease the Aggregate Stock Ownership Limit and/or the Common Stock Ownership Limit for all other
Persons; provided, however, that the decreased Aggregate Stock Ownership Limit and/or the Common Stock Ownership Limit will not be effective for any Person whose percentage ownership in Capital Stock or Common Stock, as the case may be, is in excess
of such decreased Aggregate Stock Ownership Limit and/or the Common Stock Ownership Limit until such time as such Person’s percentage of Capital Stock or Common Stock, as the case may be, equals or falls below the decreased Aggregate Stock
Ownership Limit and/or the Common Stock Ownership Limit, but any further acquisition of Capital Stock or Common Stock, as the case may be, in excess of such percentage ownership of Capital Stock or Common Stock, as the case may be, will be in
violation of the Aggregate Stock Ownership Limit and/or Common Stock Ownership Limit, and, provided further, that the new Aggregate Stock Ownership Limit and/or Common Stock Ownership Limit would not allow five or fewer Persons to Beneficially Own
more than 49% in value of the outstanding Capital Stock. 
 6.9.4 In granting a person an exemption under Section 6.9.1 or
6.9.2 above, the Board of Directors may require such Person to make certain representations or undertakings or to agree that any violation or attempted violation of such representations or undertakings (or other action which is contrary to the
restrictions contained in Section 6.2 of this Article VI) will result in such Capital Stock being transferred to a Trust in accordance with Section 6.2.2 of this Article VI. Prior to granting any exception pursuant to Section 6.9.1 or 6.9.2 of this
Article VI, the Board of Directors may require a ruling from the IRS, or an opinion of counsel, in either case in form and substance satisfactory to the Board of Directors in its sole discretion, as it may deem necessary or advisable in order to
determine or ensure the Corporation’s status as a REIT.

ARTICLES SUPPLEMENTARY 
 4,140,000 SHARES OF 
 8.50% SERIES A CUMULATIVE REDEEMABLE PREFERRED
STOCK 
 February 8, 2005 
 Digital Realty Trust, Inc., a Maryland corporation (the “Company”), hereby certifies to the State Department of Assessments and Taxation of Maryland (the “Department”)
that: 
 FIRST: Pursuant to the authority expressly vested in the Board of Directors of the Company (the “Board of
Directors”) by Article IV of the Articles of Amendment and Restatement of the Company filed with the Department on October 26, 2004 (the “Charter”) and Section 2-105 of the Maryland General Corporation Law (the
“MGCL”), the Board of Directors, by resolutions duly adopted on January 12, 2005, has authorized the classification and designation of up to 6,000,000 shares of the authorized but unissued preferred stock of the Company, par value
$.01 per share (“Preferred Stock”), as a separate class of Preferred Stock, the issuance of a maximum of 6,000,000 shares of such class of Preferred Stock, and, pursuant to the powers contained in the Bylaws of the Company and the
MGCL, appointed a committee (the “Committee”) of the Board of Directors and delegated to the Committee, to the fullest extent permitted by the MGCL and the Charter and Bylaws of the Company, among other things, all powers of the
Board of Directors with respect to (i) setting the number of shares of the Preferred Stock to be classified and designated, up to a maximum of 6,000,000 shares of Preferred Stock, (ii) choosing the cumulative dividend percentage for the Preferred
Stock, (iii) selecting the dates on which dividends will be paid on the Preferred Stock, (iv) establishing the price per share for the Preferred Stock, (v) authorizing, approving and filing these Articles Supplementary with the Department, and (vi)
authorizing and approving all such other actions as the Committee may deem necessary or desirable in connection with the classification, authorization, issuance, offer, and sale of the Preferred Stock. 

SECOND: The Committee has unanimously adopted resolutions classifying and designating the Preferred Stock as a separate class of
Preferred Stock to be known as the “8.50% Series A Cumulative Redeemable Preferred Stock,” setting the preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends and other distributions, transfers,
qualifications, terms and conditions of redemption and other terms and conditions of such 8.50% Series A Cumulative Redeemable Preferred Stock, and authorizing the issuance of up to 4,140,000 shares of 8.50% Series A Cumulative Redeemable Preferred
Stock. 
 THIRD: The designation, number of shares, preferences, rights, voting powers, restrictions, limitations as to
dividends and other distributions, qualifications, terms and conditions of redemption and other terms and conditions of the separate class of Preferred Stock of the Company designated as 8.50% Series A Cumulative Redeemable Preferred Stock are as
follows (the “Series A Terms”), which upon any restatement of the Charter shall be made a part of or incorporated by reference into the Charter with any necessary or appropriate changes to the enumeration or lettering of sections or
subsections thereof: 
 Section 1. Designation and Number. A series of Preferred Stock, designated the “8.50% Series
A Cumulative Redeemable Preferred Stock” (the “Series A Preferred Stock”), is hereby established. The number of shares of Series A Preferred Stock shall be 4,140,000. 

Section 2. Rank. The Series A Preferred Stock will, with respect to dividend rights and rights upon voluntary or involuntary
liquidation, dissolution or winding up of the Company, rank: (i) senior to all classes or series of the Company’s common stock, par value $.01 per share (the “Common Stock”), and all classes or series of capital stock of the
Company now or hereafter authorized, issued or outstanding expressly designated as ranking junior to the Series A Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation,

 
dissolution or winding up of the Company; (ii) on parity with any class or series of capital stock of the Company expressly designated as ranking on parity with the Series A Preferred Stock as to
dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company; and (iii) junior to any class or series of capital stock of the Company expressly designated as ranking senior to the Series A Preferred
Stock as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company. The term “capital stock” does not include convertible debt securities, which will rank senior to the Series
A Preferred Stock prior to conversion. 
 Section 3. Dividends. 

(a) Subject to the preferential rights of the holders of any class or series of capital stock of the Company ranking senior to the Series
A Preferred Stock as to dividends, the holders of shares of the Series A Preferred Stock shall be entitled to receive, when, as and if authorized by the Board of Directors and declared by the Company, out of funds legally available for the payment
of dividends, cumulative cash dividends at the rate of 8.50% per annum of the $25.00 liquidation preference per share of the Series A Preferred Stock (equivalent to the fixed annual amount of $2.125 per share of the Series A Preferred Stock). Such
dividends shall accrue and be cumulative from and including the first date on which any shares of Series A Preferred Stock are issued (the “Original Issue Date”) and shall be payable quarterly in arrears on each Dividend Payment
Date (as defined below), commencing March 31, 2005; provided, however, that if any Dividend Payment Date is not a Business Day (as defined below), then the dividend which would otherwise have been payable on such Dividend Payment Date may be paid on
the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case 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. The amount of any dividend payable on the Series A Preferred
Stock for any partial Dividend Period (as defined below) shall be prorated and computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends will be payable to holders of record as they appear in the stockholder records of
the Company at the close of business on the applicable Dividend Record Date (as defined below). Notwithstanding any provision to the contrary contained herein, each outstanding share of Series A Preferred Stock shall be entitled to receive a
dividend with respect to any Dividend Record Date equal to the dividend paid with respect to each other share of Series A Preferred Stock that is outstanding on such date. “Dividend Record Date” shall mean the date designated by the
Board of Directors for the payment of dividends that is not more than 35 or fewer than 10 days prior to the applicable Dividend Payment Date. “Dividend Payment Date” shall mean the last calendar day of each March, June, September
and December, commencing on March 31, 2005. “Dividend Period” shall mean the respective periods commencing on and including the first day of January, April, July and October of each year and ending on and including the day preceding
the first day of the next succeeding Dividend Period (other than the initial Dividend Period, which shall commence on the Original Issue Date and end on and include March 31, 2005, and other than the Dividend Period during which any shares of Series
A Preferred Stock shall be redeemed pursuant to Section 5, which shall end on and include the day preceding the call date with respect to the shares of Series A Preferred Stock being redeemed). 

The term “Business Day” shall mean each day, other than a Saturday or a Sunday, which is not a day on which banking
institutions in New York, New York are authorized or required by law, regulation or executive order to close. 
 (b)
Notwithstanding anything contained herein to the contrary, dividends on the Series A Preferred Stock shall accrue whether or not the Company has earnings, whether or not there are funds legally available for the payment of such dividends, and
whether or not such dividends are authorized or declared. 
 (c) Except as provided in Section 3(d) below, no dividends shall be
declared or paid or set apart for payment, and no other distribution of cash or other property may be declared or made, directly or indirectly, on or with respect to, any shares of Common Stock or shares of any other class or series of capital stock
of the Company ranking, as to dividends, on parity with or junior to the Series A Preferred Stock (other than a dividend paid in shares of Common Stock or in shares of any other class or series of capital stock ranking junior to the Series A
Preferred Stock as to dividends and upon liquidation) for any period, nor shall any shares of Common Stock or any other shares of any other class or series of capital stock of the Company ranking, as to dividends or upon liquidation, on parity with
or junior to the Series A Preferred Stock be redeemed, purchased or otherwise acquired for any 

  
 2 

 
consideration, nor shall any funds be paid or made available for a sinking fund for the redemption of such shares, and no other distribution of cash or other property may be made, directly or
indirectly, on or with respect thereto by the Company (except by conversion into or exchange for other shares of any class or series of capital stock of the Company ranking junior to the Series A Preferred Stock as to dividends and upon liquidation,
and except for the acquisition of shares made pursuant to the provisions of Article VI of the Charter or Section 7 hereof), unless full cumulative dividends on the Series A Preferred Stock for all past dividend periods and the then current dividend
period shall have been or contemporaneously are (i) declared and paid in cash or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for such payment. 

(d) When dividends are not paid in full (and a sum sufficient for such full payment is not so set apart) upon the Series A Preferred
Stock and the shares of any other class or series of capital stock ranking, as to dividends, on parity with the Series A Preferred Stock, all dividends declared upon the Series A Preferred Stock and each such other class or series of capital stock
ranking, as to dividends, on parity with the Series A Preferred Stock shall be declared pro rata so that the amount of dividends declared per share of Series A Preferred Stock and such other class or series of capital stock shall in all cases bear
to each other the same ratio that accrued dividends per share on the Series A Preferred Stock and such other class or series of capital stock (which shall not include any accrual in respect of unpaid dividends on such other class or series of
capital stock for prior dividend periods if such other class or series of capital stock does not have a cumulative dividend) bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or
payments on the Series A Preferred Stock which may be in arrears. 
 (e) Holders of shares of Series A Preferred Stock shall not
be entitled to any dividend, whether payable in cash, property or shares of stock, in excess of full cumulative dividends on the Series A Preferred Stock as provided herein. Any dividend payment made on the Series A Preferred Stock shall first be
credited against the earliest accrued but unpaid dividends due with respect to such shares which remains payable. Accrued but unpaid distributions on the Series A Preferred Stock will accumulate as of the Dividend Payment Date on which they first
become payable. 
 Section 4. Liquidation Preference. 

(a) Upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, before any distribution or
payment shall be made to holders of shares of Common Stock or any other class or series of capital stock of the Company ranking, as to rights upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company,
junior to the Series A Preferred Stock, the holders of shares of Series A Preferred Stock shall be entitled to be paid out of the assets of the Company legally available for distribution to its stockholders, after payment of or provision for the
debts and other liabilities of the Company, a liquidation preference of $25.00 per share, plus an amount equal to any accrued and unpaid dividends (whether or not declared) to but excluding the date of payment. In the event that, upon such voluntary
or involuntary liquidation, dissolution or winding up, the available assets of the Company are insufficient to pay the full amount of the liquidating distributions on all outstanding shares of Series A Preferred Stock and the corresponding amounts
payable on all shares of other classes or series of capital stock of the Company ranking, as to liquidation rights, on parity with the Series A Preferred Stock in the distribution of assets, then the holders of the Series A Preferred Stock and each
such other class or series of shares of capital stock ranking, as to voluntary or involuntary liquidation rights, on parity with the Series A Preferred Stock shall share ratably in any such distribution of assets in proportion to the full
liquidating distributions to which they would otherwise be respectively entitled. Written notice of any such voluntary or involuntary liquidation, dissolution or winding up of the Company, stating the payment date or dates when, and the place or
places where, the amounts distributable in such circumstances shall be payable, shall be given by first class mail, postage pre-paid, not fewer than 30 or more than 60 days prior to the payment date stated therein, to each record holder of shares of
Series A Preferred Stock at the respective addresses of such holders as the same shall appear on the stock transfer records of the Company. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of
Series A Preferred Stock will have no right or claim to any of the remaining assets of the Company. The consolidation or merger of the Company with or into any other corporation, trust or entity, or the voluntary sale, lease, transfer or conveyance
of all or substantially all of the property or business of the Company, shall not be deemed to constitute a liquidation, dissolution or winding up of the affairs of the Company. 

  
 3 

 (b) In determining whether a distribution (other than upon voluntary or involuntary
liquidation), by dividend, redemption or other acquisition of shares of stock of the Company or otherwise, is permitted under the MGCL, amounts that would be needed, if the Company were to be dissolved at the time of the distribution, to satisfy the
preferential rights upon dissolution of holders of shares of Series A Preferred Stock shall not be added to the Company’s total liabilities. 
 Section 5. Redemption. 
 (a) Shares of Series A Preferred Stock shall not be
redeemable prior to February 9, 2010 except to preserve the status of the Company as a REIT for United States federal income tax purposes. In addition, the Series A Preferred Stock shall be subject to the provisions of Section 7 pursuant to which
Series A Preferred Stock owned by a stockholder in excess of the Ownership Limit shall automatically be transferred to a Trust for the exclusive benefit of a Charitable Beneficiary. 

(b) On and after February 9, 2010, the Company, at its option upon not fewer than 30 or more than 60 days’ written notice, may
redeem the Series A Preferred Stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends (whether or not declared) thereon up to but not including the date
fixed for redemption, without interest, to the extent the Company has funds legally available therefor. If fewer than all of the outstanding shares of Series A Preferred Stock are to be redeemed, the shares of Series A Preferred Stock to be redeemed
shall be redeemed pro rata (as nearly as may be practicable without creating fractional shares) by lot or by any other equitable method determined by the Company that will not result in a violation of the Ownership Limit. If redemption is to be by
lot and, as a result, any holder of shares of Series A Preferred Stock would have actual ownership, Beneficial Ownership or Constructive Ownership (as defined in Section 7(a)) in excess of the Ownership Limit (as defined in Section 7(a)), or such
other limit as permitted by the Board of Directors or the Committee pursuant to Section 7(i), because such holder’s shares of Series A Preferred Stock were not redeemed, or were only redeemed in part, then, except as otherwise provided in the
Charter, the Company shall redeem the requisite number of shares of Series A Preferred Stock of such holder such that no holder will hold an amount of Series A Preferred Stock in excess of the Ownership Limit or such other limit, as applicable,
subsequent to such redemption. Holders of Series A Preferred Stock to be redeemed shall surrender such Series A Preferred Stock at the place designated in such notice and shall be entitled to the redemption price of $25.00 per share and any accrued
and unpaid dividends payable upon such redemption following such surrender. If (i) notice of redemption of any shares of Series A Preferred Stock has been given, (ii) the funds necessary for such redemption have been set aside by the Company in
trust for the benefit of the holders of any shares of Series A Preferred Stock so called for redemption, and (iii) irrevocable instructions have been given to pay the redemption price and all accrued and unpaid dividends, then from and after the
redemption date, dividends shall cease to accrue on such shares of Series A Preferred Stock, such shares of Series A Preferred Stock shall no longer be deemed outstanding, and all rights of the holders of such shares shall terminate, except the
right to receive the redemption price plus any accrued and unpaid dividends payable upon such redemption, without interest. So long as no dividends are in arrears, nothing herein shall prevent or restrict the Company’s right or ability to
purchase, from time to time, either at a public or a private sale, all or any part of the Series A Preferred Stock at such price or prices as the Company may determine, subject to the provisions of applicable law, including the repurchase of shares
of Series A Preferred Stock in open-market transactions duly authorized by the Board of Directors. 
 (c) In the event of any
redemption of the Series A Preferred Stock in order to preserve the status of the Company as a REIT for United States federal income tax purposes, such redemption shall be made in accordance with the terms and conditions set forth in this Section 5
of these Articles Supplementary. If the Company calls for redemption any shares of Series A Preferred Stock pursuant to and in accordance with this Section 5(c), then the redemption price for such shares will be an amount in cash equal to $25.00 per
share together with all accrued and unpaid dividends to but excluding the dated fixed for redemption. 
 (d) Unless full
cumulative dividends on all Series A Preferred Stock shall have been or contemporaneously are authorized, declared and paid in cash, or declared and a sum sufficient for the payment thereof in cash set apart for payment for all past dividend periods
and the then current dividend period, no shares of Series A Preferred Stock shall be redeemed unless all outstanding shares of Series A Preferred Stock are simultaneously redeemed, and the Company shall not purchase or otherwise acquire directly or
indirectly any shares of Series A Preferred Stock or any class or series of capital stock of the Company ranking, as to dividends or upon 

  
 4 

 
liquidation, on parity with or junior to the Series A Preferred Stock (except by exchange for shares of capital stock of the Company ranking, as to dividends and upon liquidation, junior to the
Series A Preferred Stock); provided, however, that the foregoing shall not prevent the purchase of Series A Preferred Stock by the Company in accordance with the terms of Sections 5(c) and 7 of these Articles Supplementary or otherwise
in order to ensure that the Company remains qualified as a REIT for United States federal income tax purposes, or the purchase or acquisition of Series A Preferred Stock pursuant to a purchase or exchange offer made on the same terms to holders of
all outstanding shares of Series A Preferred Stock. 
 (e) Notice of redemption will be given by publication in a newspaper of
general circulation in the City of New York, such publication to be made once a week for two successive weeks commencing not fewer than 30 or more than 60 days prior to the redemption date. A similar notice will be mailed by the Company, postage
prepaid, not fewer than 30 or more than 60 days prior to the redemption date, addressed to the respective holders of record of the Series A Preferred Stock to be redeemed at their respective addresses as they appear on the transfer records of the
Company. No failure to give or defect in such notice shall affect the validity of the proceedings for the redemption of any Series A Preferred Stock except as to the holder to whom such notice was defective or not given. In addition to any
information required by law or by the applicable rules of any exchange upon which the Series A Preferred Stock may be listed or admitted to trading, each such notice shall state: (i) the redemption date, (ii) the redemption price, (iii) the number
of shares of Series A Preferred Stock to be redeemed, (iv) the place or places where the certificates representing shares of Series A Preferred Stock are to be surrendered for payment of the redemption price, (v) that dividends on the shares of
Series A Preferred Stock to be redeemed will cease to accumulate on such redemption date and (vi) that payment of the redemption price and any accumulated and unpaid dividends will be made upon presentation and surrender of such Series A Preferred
Stock. If fewer than all of the shares of Series A Preferred Stock held by any holder are to be redeemed, the notice mailed to such holder shall also specify the number of shares of Series A Preferred Stock held by such holder to be redeemed.
Notwithstanding anything else to the contrary in these Articles Supplementary, the Company shall not be required to provide notice to the holder of Series A Preferred Stock in the event such holder’s Series A Preferred Stock is redeemed in
accordance with Section 7 of these Articles Supplementary to preserve the Company’s status as a REIT. 
 (f) If a
redemption date falls after a Dividend Record Date and on or prior to the corresponding Dividend Payment Date, each holder of Series A Preferred Stock at the close of business of such Dividend Record Date shall be entitled to the dividend payable on
such shares on the corresponding Dividend Payment Date notwithstanding the redemption of such shares on or prior to such Dividend Payment Date, and each holder of Series A Preferred Stock that surrenders its shares on such redemption date will be
entitled to the dividends accruing after the end of the Dividend Period to which such Dividend Payment Date relates up to but excluding the redemption date. Except as provided herein, the Company shall make no payment or allowance for unpaid
dividends, whether or not in arrears, on Series A Preferred Stock for which a notice of redemption has been given. 
 (g) All
shares of the Series A Preferred Stock redeemed or repurchased pursuant to this Section 5 shall be retired and shall be restored to the status of authorized but unissued shares of Preferred Stock, without designation as to series or class.

 (h) The Series A Preferred Stock shall have no stated maturity and shall not be subject to any sinking fund or mandatory
redemption; provided, however, that the Series A Preferred Stock owned by a stockholder in excess of the Ownership Limit shall be subject to the provisions of this Section 5 and Section 7 of these Articles Supplementary. 

Section 6. Voting Rights. 
 (a) Holders of the Series A Preferred Stock shall not have any voting rights, except as set forth in this Section 6. 
 (b) Whenever dividends on any shares of Series A Preferred Stock shall be in arrears for six or more consecutive or non-consecutive quarterly periods (a “Preferred Dividend Default”), the
holders of such Series A Preferred Stock (voting as a single class with all other classes or series of preferred stock of the Company upon which like voting rights have been conferred and are exercisable (“Parity Preferred”)) shall
be entitled to vote for the election of a total of two additional directors of the Company (the “Preferred Directors”) until all dividends 

  
 5 

 
accumulated on such Series A Preferred Stock and Parity Preferred for the past dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for
payment. In such case, the entire Board of Directors will be increased by two directors. 
 (c) The Preferred Directors will be
elected by a plurality of the votes cast in the election for a one-year term and each Preferred Director will serve until his or her successor is duly elected and qualified or until such Preferred Director’s right to hold the office terminates,
whichever occurs earlier, subject to such Preferred Director’s earlier death, disqualification, resignation or removal. The election will take place at (i) either (A) a special meeting called in accordance with Section 6(d) below if the request
is received more than 90 days before the date fixed for the Company’s next annual or special meeting of stockholders or (B) the next annual or special meeting of stockholders if the request is received within 90 days of the date fixed for the
Company’s next annual or special meeting of stockholders, and (ii) at each subsequent annual meeting of stockholders, or special meeting held in place thereof, until all such dividends in arrears on the Series A Preferred Stock and each such
class or series of outstanding Parity Preferred have been paid in full. A dividend in respect of Series A Preferred Stock shall be considered timely made if made within two Business Days after the applicable Dividend Payment Date if at the time of
such late payment date there shall not be any prior quarterly dividend periods in respect of which full dividends were not timely made at the applicable Dividend Payment Date. 
 (d) At any time when such voting rights shall have vested, a proper officer of the Company shall call or cause to be called, upon written request of holders of record of at least 10% of the outstanding
shares of Series A Preferred Stock and Parity Preferred, a special meeting of the holders of Series A Preferred Stock and each class or series of Parity Preferred by mailing or causing to be mailed to such holders a notice of such special meeting to
be held not fewer than ten or more than 45 days after the date such notice is given. The record date for determining holders of the Series A Preferred Stock and Parity Preferred entitled to notice of and to vote at such special meeting will be the
close of business on the third Business Day preceding the day on which such notice is mailed. At any such annual or special meeting, all of the holders of the Series A Preferred Stock and Parity Preferred, by plurality vote, voting together as a
single class without regard to class or series will be entitled to elect two directors on the basis of one vote per $25.00 of liquidation preference to which such Parity Preferred are entitled by their terms (excluding amounts in respect of
accumulated and unpaid dividends) and not cumulatively. The holder or holders of one-third of the Series A Preferred stock and Parity Preferred voting as a single class then outstanding, present in person or by proxy, will constitute a quorum for
the election of the Preferred Directors except as otherwise provided by law. Notice of all meetings at which holders of the Series A Preferred Stock and the Parity Preferred shall be entitled to vote will be given to such holders at their addresses
as they appear in the transfer records. At any such meeting or adjournment thereof in the absence of a quorum, subject to the provisions of any applicable law, a majority of the holders of the Series A Preferred and Parity Preferred voting as a
single class present in person or by proxy shall have the power to adjourn the meeting for the election of the Preferred Directors, without notice other than an announcement at the meeting, until a quorum is present. If a Preferred Dividend Default
shall terminate after the notice of a special meeting has been given but before such special meeting has been held, the Company shall, as soon as practicable after such termination, mail or cause to be mailed notice of such termination to holders of
the Series A Preferred Stock and the Parity Preferred that would have been entitled to vote at such special meeting. 
 (e) If
and when all accumulated dividends on such Series A Preferred Stock and all classes or series of Parity Preferred for the past dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for
payment, the right of the holders of Series A Preferred Stock and the Parity Preferred to elect such additional two directors shall immediately cease (subject to revesting in the event of each and every Preferred Dividend Default), and the term of
office of each Preferred Director so elected shall terminate and the entire Board of Directors shall be reduced accordingly. Any Preferred Director may be removed at any time with or without cause by the vote of, and shall not be removed otherwise
than by the vote of, the holders of record of a majority of the outstanding Series A Preferred Stock and the Parity Preferred entitled to vote thereon when they have the voting rights set forth in Section 6(b) (voting as a single class). So long as
a Preferred Dividend Default shall continue, any vacancy in the office of a Preferred Director may be filled by written consent of the Preferred Director remaining in office, or if none remains in office, by a vote of the holders of record of a
majority of the outstanding Series A Preferred Stock when they have the voting rights described above (voting as a single class with all other classes or series of Parity Preferred). Each of the Preferred Directors shall be entitled to one vote on
any matter. 

  
 6 

 (f) So long as any shares of Series A Preferred Stock remain outstanding, the affirmative
vote or consent of the holders of two-thirds of the shares of Series A Preferred Stock and each other class or series of preferred stock ranking on parity with the Series A Preferred Stock with respect to the payment of dividends and the
distribution of assets upon liquidation, dissolution or winding up of the Company upon which like voting rights have been conferred outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting as a single class)
will be required to: (i) authorize, create or issue, or increase the authorized or issued amount of, any class or series of capital stock ranking senior to the Series A Preferred Stock with respect to payment of dividends or the distribution of
assets upon liquidation, dissolution or winding up of the affairs of the Company or reclassify any authorized shares of capital stock of the Company into such capital stock, or create, authorize or issue any obligation or security convertible into
or evidencing the right to purchase any such capital stock; or (ii) amend, alter or repeal the provisions of the Charter or the terms of the Series A Preferred Stock, whether by merger, consolidation, transfer or conveyance of all or substantially
all of its assets or otherwise (an “Event”), so as to materially and adversely affect any right, preference, privilege or voting power of the Series A Preferred Stock; provided however, with respect to the occurrence
of any of the Events set forth in (ii) above, so long as the Series A Preferred Stock remains outstanding with the terms thereof materially unchanged, taking into account that, upon the occurrence of an Event, the Company may not be the surviving

(c) Transfers of Series A Preferred Stock in Trust. 
 (i) Upon any purported Transfer or other event described in Section 7(b)(ii) of these Articles Supplementary, such Series A Preferred Stock shall be deemed to have been transferred to the Trustee in his

rights shall be exercised for the exclusive benefit of the Charitable Beneficiary. Any dividend or distribution paid to or on behalf of the Purported Record Transferee or Purported Beneficial Transferee prior to the discovery by the Company that
shares of Series A Preferred Stock have been transferred to the Trustee shall be paid to the Trustee upon demand, and any dividend or distribution declared but unpaid shall be paid when due to the Trustee with respect to such Series A Preferred
Stock. Any dividends or distributions so paid over to the Trustee shall be held in trust for the Charitable Beneficiary. The Purported Record Transferee and Purported Beneficial Transferee shall have no voting rights with respect to the Series A
Preferred Stock held in the Trust and, subject to Maryland law, effective as of the date the Series A Preferred Stock has been transferred to the Trustee, the Trustee shall have the authority (at the Trustee’s sole discretion) (i) to rescind as
void any vote cast by a Purported Record Transferee with respect to such Series A Preferred Stock prior to the discovery by the Company that the Series A Preferred Stock has been transferred to the Trustee and (ii) to recast such vote in accordance
with the desires of the Trustee acting for the benefit of the Charitable Beneficiary; provided, however, that if the Company has already taken irreversible corporate action, then the Trustee shall not have the authority to rescind and recast
such vote. Notwithstanding any other provision of these Articles Supplementary to the contrary, until the Company has received notification that the Series A Preferred Stock has been transferred into a Trust, the Company shall be entitled to rely on
its share transfer and other stockholder records for purposes of preparing lists of stockholders entitled to vote at meetings, determining the validity and authority of proxies and otherwise conducting votes of stockholders. 

(iv) Within twenty (20) days of receiving notice from the Company that shares of Series A Preferred Stock have been transferred to the
Trust, the Trustee of the Trust shall sell the shares of Series A Preferred Stock held in the Trust to a Person, designated by the Trustee, whose ownership of the shares of Series A Preferred Stock will not violate the ownership limitations set

to the Charitable Beneficiary as provided in this Section 7(c)(iv). The Purported Record Transferee shall receive the lesser of (i) the price paid by the Purported 

  
 10 

 
Record Transferee for the shares of Series A Preferred Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not
involve a purchase of such shares of Series A Preferred Stock at Market Price, the Market Price of such shares of Series A Preferred Stock on the day of the event which resulted in the transfer of such shares of Series A Preferred Stock to the
Trust) and (ii) the price per share received by the Trustee (net of any commissions and other expenses of sale) from the sale or other disposition of the shares of Series A Preferred Stock held in the Trust. The Trustee may reduce the amount payable
to the Purported Record Transferee by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 7(c)(iii). Any net sales
proceeds in excess of the amount payable to the Purported Record Transferee shall be immediately paid to the Charitable Beneficiary together with any dividends or other distributions thereon. If, prior to the discovery by the Company that shares of
such Series A Preferred Stock have been transferred to the Trustee, such shares of Series A Preferred Stock are sold by a Purported Record Transferee then (i) such shares of Series A Preferred Stock shall be deemed to have been sold on behalf of the
Trust and (ii) to the extent that the Purported Record Transferee received an amount for such shares of Series A Preferred Stock that exceeds the amount that such Purported Record Transferee was entitled to receive pursuant to this Section 7(c)(iv),
such excess shall be paid to the Trustee upon demand. 
 (v) Series A Preferred Stock transferred to the Trustee shall be deemed
to have been offered for sale to the Company, or its designee, at a price per share equal to the lesser of (i) the price paid by the Purported Record Transferee for the shares of Series A Preferred Stock in the transaction that resulted in such
transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Series A Preferred Stock at Market Price, the Market Price of such shares of Series A Preferred Stock on the day of the
event which resulted in the transfer of such shares of Series A Preferred Stock to the Trust) and (ii) the Market Price on the date the Company, or its designee, accepts such offer. The Company may reduce the amount payable to the Purported Record
Transferee by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 7(c)(iii). The Company shall have the right to accept
such offer until the Trustee has sold the shares of Series A Preferred Stock held in the Trust pursuant to Section 7(c)(iv). Upon such a sale to the Company, the interest of the Charitable Beneficiary in the shares of Series A Preferred Stock sold
shall terminate and the Trustee shall distribute the net proceeds of the sale to the Purported Record Transferee and any dividends or other distributions held by the Trustee with respect to such Series A Preferred Stock shall thereupon be paid to
the Charitable Beneficiary. 
 (vi) By written notice to the Trustee, the Company shall designate one or more nonprofit
organizations to be the Charitable Beneficiary of the interest in the Trust such that the Series A Preferred Stock held in the Trust would not violate the restrictions set forth in Section 7(b)(i) in the hands of such Charitable Beneficiary.

 (d) Remedies For Breach. If the Board of Directors or a committee thereof or other designees if permitted by the MGCL
shall at any time determine in good faith that a Transfer or other event has taken place in violation of Section 7(b) of these Articles Supplementary or that a Person intends to acquire, has attempted to acquire or may acquire beneficial ownership
(determined without reference to any rules of attribution), Beneficial Ownership or Constructive Ownership of any shares of Series A Preferred Stock of the Company in violation of Section 7(b) of these Articles Supplementary, the Board of Directors
or the Committee or other designees if permitted by the MGCL shall take such action as it deems advisable to refuse to give effect or to prevent such Transfer, including, but not limited to, causing the Company to redeem shares of Series A Preferred
Stock, refusing to give effect to such Transfer on the books of the Company or instituting proceedings to enjoin such Transfer; provided, however, that any Transfers (or, in the case of events other than a Transfer, ownership or Constructive
Ownership or Beneficial Ownership) in violation of Section 7(b)(i) of these Articles Supplementary, shall automatically result in the transfer to a Trust as described in Section 7(b)(ii) and any Transfer in violation of Section 7(b)(iii) shall
automatically be void ab initio irrespective of any action (or non-action) by the Board of Directors. 
 (e) Notice of
Restricted Transfer. Any Person who acquires or attempts to acquire shares of Series A Preferred Stock in violation of Section 7(b) of these Articles Supplementary, or any Person who is a Purported Beneficial Transferee such that an automatic
transfer to a Trust results under Section 7(b)(ii) of these Articles Supplementary, shall immediately give written notice to the Company of such event and shall provide to the Company such other information as the Company may request in order to
determine the effect, if any of such Transfer or attempted Transfer on the Company’s status as a REIT. 

  
 11 

 (f) Owners Required To Provide Information. Prior to the Restriction Termination Date
each Person who is a beneficial owner or Beneficial Owner or Constructive Owner of Series A Preferred Stock and each Person (including the stockholder of record) who is holding Series A Preferred Stock for a beneficial owner or Beneficial Owner or
Constructive Owner shall provide to the Company such information that the Company may request, in good faith, in order to determine the Company’s status as a REIT. 
 (g) Remedies Not Limited. Nothing contained in these Articles Supplementary (but subject to Section 7(l) of these Articles Supplementary) shall limit the authority of the Board of Directors to take
such other action as it deems necessary or advisable to protect the Company and the interests of its stockholders by preservation of the Company’s status as a REIT. 
 (h) Ambiguity. In the case of an ambiguity in the application of any of the provisions of this Section 7 of these Articles Supplementary, including any definition contained in Section 7(a), the
Board of Directors shall have the power to determine the application of the provisions of this Section 7 with respect to any situation based on the facts known to it (subject, however, to the provisions of Section 7(l) of these Articles
Supplementary). In the event Section 7 requires an action by the Board of Directors and these Articles Supplementary fail to provide specific guidance with respect to such action, the Board of Directors shall have the power to determine the action
to be taken so long as such action is not contrary to the provisions of Section 7. Absent a decision to the contrary by the Board of Directors (which the Board of Directors may make in its sole and absolute discretion), if a Person would have (but
for the remedies set forth in Section 7(b)) acquired Beneficial or Constructive Ownership of Series A Preferred Stock in violation of Section 7(b)(i), such remedies (as applicable) shall apply first to the shares of Series A Preferred Stock which,
but for such remedies, would have been actually owned by such Person, and second to shares of Series A Preferred Stock, which, but for such remedies, would have been Beneficially Owned or Constructively Owned (but not actually owned) by such Person,
pro rata among the Persons who actually own such shares of Series A Preferred Stock based upon the relative number of the shares of Series A Preferred Stock held by each such Person. 

(i) Exceptions. 
 (i) Subject to Section 7(b)(i)(C), the Board of Directors, in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Beneficially Owning shares of Series
A Preferred Stock in violation of Section 7(b)(i)(A) if the Board of Directors determines that such exemption will not cause any Individual’s Beneficial Ownership of shares of Capital Stock to violate the Aggregate Stock Ownership Limit and
that such exemption will not cause the Company to fail to qualify as a REIT under the Code. 
 (ii) Subject to Section
7(b)(i)(C), the Board of Directors in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Constructively Owning Series A Preferred Stock in violation of Section 7(b)(i)(B), if the Board of
Directors determines that such ownership would not cause the Company to fail to qualify as a REIT under the Code. 
 (iii)
Subject to Section 7(b)(i)(C) and the remainder of this Section 7(i)(iii), the Board of Directors may from time to time increase or decrease the Ownership Limit; provided, however, that the decreased Ownership Limit will not be
effective for any Person whose percentage ownership of Series A Preferred Stock is in excess of such decreased Ownership Limit until such time as such Person’s percentage of Series A Preferred Stock equals or falls below the decreased Ownership
Limit, but any further acquisition of Series A Preferred Stock in excess of such percentage ownership of Series A Preferred Stock will be in violation of the Ownership Limit, and, provided further, that the new Ownership Limit would not allow five
or fewer Persons to Beneficially Own more than 49% in value of the outstanding capital stock of the Company. 
 (iv) In granting
a person an exemption under Section 7(i)(i) or (ii) above, the Board of Directors may require such Person to make certain representations or undertakings or to agree that any violation or attempted violation of such representations or undertakings
(or other action which is contrary to the restrictions contained in Section 7(b) of these Articles Supplementary) will result in such Series A Preferred Stock being transferred to a Trust in accordance with Section 7(b)(ii) of these Articles
Supplementary. In granting any exception pursuant to Section 7(i)(i) or (ii) of these Articles Supplementary, the Board of Directors may require a ruling from the IRS, or an opinion of counsel, in either case in form and substance satisfactory to
the Board of Directors in its sole discretion, as it may deem necessary or advisable in order to determine or ensure the Company’s status as a REIT.

STOCK 
 JULY 25, 2005 
 Digital Realty Trust, Inc., a Maryland corporation (the “Company”), hereby certifies to the State Department of Assessments and Taxation of Maryland (the “Department”)
that: 
 FIRST: Pursuant to the authority expressly vested in the Board of Directors of the Company (the “Board of

of the authorized but unissued preferred stock of the Company, par value $.01 per share (“Preferred Stock”), as a separate class of Preferred Stock, the issuance of a maximum of 3,600,000 shares (plus up to an additional 15% to
cover any underwriter over-allotment option) of such class of Preferred Stock, and, pursuant to the powers contained in the Bylaws of the Company and the MGCL, appointed a committee (the “Committee”) of the Board of Directors and
delegated to the Committee, to the fullest extent permitted by the MGCL and the Charter and Bylaws of the Company, among other things, all powers of the Board of Directors with respect to (i) setting the number of shares of the Preferred Stock to be
classified and designated, up to a maximum of 3,600,000 shares (plus up to an additional 15% to cover any underwriter over-allotment option) of Preferred Stock, (ii) choosing the cumulative dividend percentage for the Preferred Stock, (iii)
selecting the dates on which dividends will be paid on the Preferred Stock, (iv) establishing the price per share for the Preferred Stock, (v) authorizing, approving and filing these Articles Supplementary with the Department, and (vi) authorizing
and approving all such other actions as the Committee may deem necessary or desirable in connection with the classification, authorization, issuance, offer, and sale of the Preferred Stock. 

SECOND: The Committee has unanimously adopted resolutions classifying and designating the Preferred Stock as a separate class of
Preferred Stock to be known as the “7.875% Series B Cumulative Redeemable Preferred Stock,” setting the preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends and other distributions, transfers,
qualifications, terms and conditions of redemption and other terms and conditions of such 7.875% Series B Cumulative Redeemable Preferred Stock, and authorizing the issuance of up to 2,530,000 shares of 7.875% Series B Cumulative Redeemable
Preferred Stock. 
 THIRD: The designation, number of shares, preferences, rights, voting powers, restrictions,
limitations as to dividends and other distributions, qualifications, terms and conditions of redemption and other terms and conditions of the separate class of Preferred Stock of the Company designated as 7.875% Series B Cumulative Redeemable
Preferred Stock are as follows (the “Series B Terms”), which upon any restatement of the Charter shall be made a part of or incorporated by reference into the Charter with any necessary or appropriate changes to the enumeration or
lettering of sections or subsections thereof: 
 Section 1. Designation and Number. A series of Preferred Stock,
designated the “7.875% Series B Cumulative Redeemable Preferred Stock” (the “Series B Preferred Stock”), is hereby established. The number of shares of Series B Preferred Stock shall be 2,530,000. 

Section 2. Rank. The Series B Preferred Stock will, with respect to dividend rights and rights upon voluntary or involuntary
liquidation, dissolution or winding up of the Company, rank: (i) senior to all classes or series of the Company’s common stock, par value $.01 per share (the “Common Stock”), and all classes or series of

 
capital stock of the Company now or hereafter authorized, issued or outstanding expressly designated as ranking junior to the Series B Preferred Stock as to dividend rights and rights upon
voluntary or involuntary liquidation, dissolution or winding up of the Company; (ii) on parity with Series A Cumulative Redeemable Preferred Stock of the Company and with any class or series of capital stock of the Company expressly designated as
ranking on parity with the Series B Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company; and (iii) junior to any class or series of capital stock of the Company
expressly designated as ranking senior to the Series B Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company. The term “capital stock” does not include
convertible debt securities, which will rank senior to the Series B Preferred Stock prior to conversion. 
 Section 3.
Dividends. 
 (a) Subject to the preferential rights of the holders of any class or series of capital stock of the Company
ranking senior to the Series B Preferred Stock as to dividends, the holders of shares of the Series B Preferred Stock shall be entitled to receive, when, as and if authorized by the Board of Directors and declared by the Company, out of funds
legally available for the payment of dividends, cumulative cash dividends at the rate of 7.875% per annum of the $25.00 liquidation preference per share of the Series B Preferred Stock (equivalent to the fixed annual amount of $1.96875 per share of
the Series B Preferred Stock). Such dividends shall accrue and be cumulative from and including the first date on which any shares of Series B Preferred Stock are issued (the “Original Issue Date”) and shall be payable quarterly in
arrears on each Dividend Payment Date (as defined below), commencing September 30, 2005; provided, however, that if any Dividend Payment Date is not a Business Day (as defined below), then the dividend which would otherwise have been payable on such
Dividend Payment Date may be paid on the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case 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. The amount of any dividend payable
on the Series B Preferred Stock for any partial Dividend Period (as defined below) shall be prorated and computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends will be payable to holders of record as they appear in the
stockholder records of the Company at the close of business on the applicable Dividend Record Date (as defined below). Notwithstanding any provision to the contrary contained herein, each outstanding share of Series B Preferred Stock shall be
entitled to receive a dividend with respect to any Dividend Record Date equal to the dividend paid with respect to each other share of Series B Preferred Stock that is outstanding on such date. “Dividend Record Date” shall mean the
date designated by the Board of Directors for the payment of dividends that is not more than 35 or fewer than 10 days prior to the applicable Dividend Payment Date. “Dividend Payment Date” shall mean the last calendar day of each
March, June, September and December, commencing on September 30, 2005. “Dividend Period” shall mean the respective periods commencing on and including the first day of January, April, July and October of each year and ending on and
including the day preceding the first day of the next succeeding Dividend Period (other than the initial Dividend Period, which shall commence on the Original Issue Date and end on and include September 30, 2005, and other than the Dividend Period
during which any shares of Series B Preferred Stock shall be redeemed pursuant to Section 5, which shall end on and include the day preceding the call date with respect to the shares of Series B Preferred Stock being redeemed). 

The term “Business Day” shall mean each day, other than a Saturday or a Sunday, which is not a day on which banking
institutions in New York, New York are authorized or required by law, regulation or executive order to close. 
 (b)
Notwithstanding anything contained herein to the contrary, dividends on the Series B Preferred Stock shall accrue whether or not the Company has earnings, whether or not there are funds legally available for the payment of such dividends, and
whether or not such dividends are authorized or declared. 
 (c) Except as provided in Section 3(d) below, no dividends shall be
declared or paid or set apart for payment, and no other distribution of cash or other property may be declared or made, directly or indirectly, on or with respect to, any shares of Common Stock or shares of any other class or series of capital stock
of the Company ranking, as to dividends, on parity with or junior to the Series B Preferred Stock (other than a dividend paid in shares of Common Stock or in shares of any other class or series of capital stock ranking junior to the Series B
Preferred 

  
 2 

 
Stock as to dividends and upon liquidation) for any period, nor shall any shares of Common Stock or any other shares of any other class or series of capital stock of the Company ranking, as to
dividends or upon liquidation, on parity with or junior to the Series B Preferred Stock be redeemed, purchased or otherwise acquired for any consideration, nor shall any funds be paid or made available for a sinking fund for the redemption of such
shares, and no other distribution of cash or other property may be made, directly or indirectly, on or with respect thereto by the Company (except by conversion into or exchange for other shares of any class or series of capital stock of the Company
ranking junior to the Series B Preferred Stock as to dividends and upon liquidation, and except for the acquisition of shares made pursuant to the provisions of Article VI of the Charter or Section 7 hereof), unless full cumulative dividends on the
Series B Preferred Stock for all past dividend periods shall have been or contemporaneously are (i) declared and paid in cash or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for such payment. 

(d) When dividends are not paid in full (and a sum sufficient for such full payment is not so set apart) upon the Series B Preferred
Stock and the shares of any other class or series of capital stock ranking, as to dividends, on parity with the Series B Preferred Stock, all dividends declared upon the Series B Preferred Stock and each such other class or series of capital stock
ranking, as to dividends, on parity with the Series B Preferred Stock shall be declared pro rata so that the amount of dividends declared per share of Series B Preferred Stock and such other class or series of capital stock shall in all cases bear
to each other the same ratio that accrued dividends per share on the Series B Preferred Stock and such other class or series of capital stock (which shall not include any accrual in respect of unpaid dividends on such other class or series of
capital stock for prior dividend periods if such other class or series of capital stock does not have a cumulative dividend) bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or
payments on the Series B Preferred Stock which may be in arrears. 
 (e) Holders of shares of Series B Preferred Stock shall not
be entitled to any dividend, whether payable in cash, property or shares of stock, in excess of full cumulative dividends on the Series B Preferred Stock as provided herein. Any dividend payment made on the Series B Preferred Stock shall first be
credited against the earliest accrued but unpaid dividends due with respect to such shares which remains payable. Accrued but unpaid distributions on the Series B Preferred Stock will accumulate as of the Dividend Payment Date on which they first
become payable. 
 Section 4. Liquidation Preference. 

(a) Upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, before any distribution or
payment shall be made to holders of shares of Common Stock or any other class or series of capital stock of the Company ranking, as to rights upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company,
junior to the Series B Preferred Stock, the holders of shares of Series B Preferred Stock shall be entitled to be paid out of the assets of the Company legally available for distribution to its stockholders, after payment of or provision for the
debts and other liabilities of the Company, a liquidation preference of $25.00 per share, plus an amount equal to any accrued and unpaid dividends (whether or not declared) to but excluding the date of payment. In the event that, upon such voluntary
or involuntary liquidation, dissolution or winding up, the available assets of the Company are insufficient to pay the full amount of the liquidating distributions on all outstanding shares of Series B Preferred Stock and the corresponding amounts
payable on all shares of other classes or series of capital stock of the Company ranking, as to liquidation rights, on parity with the Series B Preferred Stock in the distribution of assets, then the holders of the Series B Preferred Stock and each
such other class or series of shares of capital stock ranking, as to voluntary or involuntary liquidation rights, on parity with the Series B Preferred Stock shall share ratably in any such distribution of assets in proportion to the full
liquidating distributions to which they would otherwise be respectively entitled. Written notice of any such voluntary or involuntary liquidation, dissolution or winding up of the Company, stating the payment date or dates when, and the place or
places where, the amounts distributable in such circumstances shall be payable, shall be given by first class mail, postage pre-paid, not fewer than 30 or more than 60 days prior to the payment date stated therein, to each record holder of shares of
Series B Preferred Stock at the respective addresses of such holders as the same shall appear on the stock transfer records of the Company. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of
Series B Preferred Stock will have no right or claim to any of the remaining assets of the Company. The consolidation or merger of the Company with or into any other corporation, trust or entity, or the voluntary sale, lease, transfer or conveyance
of all or substantially all of the property or business of the Company, shall not be deemed to constitute a liquidation, dissolution or winding up of the affairs of the Company. 

  
 3 

 (b) In determining whether a distribution (other than upon voluntary or involuntary
liquidation), by dividend, redemption or other acquisition of shares of stock of the Company or otherwise, is permitted under the MGCL, amounts that would be needed, if the Company were to be dissolved at the time of the distribution, to satisfy the
preferential rights upon dissolution of holders of shares of Series B Preferred Stock shall not be added to the Company’s total liabilities. 
 Section 5. Redemption. 
 (a) Shares of Series B Preferred Stock shall not be
redeemable prior to July 26, 2010 except to preserve the status of the Company as a REIT for United States federal income tax purposes. In addition, the Series B Preferred Stock shall be subject to the provisions of Section 7 pursuant to which
Series B Preferred Stock owned by a stockholder in excess of the Ownership Limit shall automatically be transferred to a Trust for the exclusive benefit of a Charitable Beneficiary. 

(b) On and after July 26, 2010, the Company, at its option upon not fewer than 30 or more than 60 days’ written notice, may redeem
the Series B Preferred Stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends (whether or not declared) thereon up to but not including the date fixed
for redemption, without interest, to the extent the Company has funds legally available therefor. If fewer than all of the outstanding shares of Series B Preferred Stock are to be redeemed, the shares of Series B Preferred Stock to be redeemed shall
be redeemed pro rata (as nearly as may be practicable without creating fractional shares) by lot or by any other equitable method determined by the Company that will not result in a violation of the Ownership Limit. If redemption is to be by lot
and, as a result, any holder of shares of Series B Preferred Stock would have actual ownership, Beneficial Ownership or Constructive Ownership (as defined in Section 7(a)) in excess of the Ownership Limit (as defined in Section 7(a)), or such other
limit as permitted by the Board of Directors or the Committee pursuant to Section 7(i), because such holder’s shares of Series B Preferred Stock were not redeemed, or were only redeemed in part, then, except as otherwise provided in the
Charter, the Company shall redeem the requisite number of shares of Series B Preferred Stock of such holder such that no holder will hold an amount of Series B Preferred Stock in excess of the Ownership Limit or such other limit, as applicable,
subsequent to such redemption. Holders of Series B Preferred Stock to be redeemed shall surrender such Series B Preferred Stock at the place designated in such notice and shall be entitled to the redemption price of $25.00 per share and any accrued
and unpaid dividends payable upon such redemption following such surrender. If (i) notice of redemption of any shares of Series B Preferred Stock has been given, (ii) the funds necessary for such redemption have been set aside by the Company in
trust for the benefit of the holders of any shares of Series B Preferred Stock so called for redemption, and (iii) irrevocable instructions have been given to pay the redemption price and all accrued and unpaid dividends, then from and after the
redemption date, dividends shall cease to accrue on such shares of Series B Preferred Stock, such shares of Series B Preferred Stock shall no longer be deemed outstanding, and all rights of the holders of such shares shall terminate, except the
right to receive the redemption price plus any accrued and unpaid dividends payable upon such redemption, without interest. So long as no dividends are in arrears, nothing herein shall prevent or restrict the Company’s right or ability to
purchase, from time to time, either at a public or a private sale, all or any part of the Series B Preferred Stock at such price or prices as the Company may determine, subject to the provisions of applicable law, including the repurchase of shares
of Series B Preferred Stock in open-market transactions duly authorized by the Board of Directors. 
 (c) In the event of any
redemption of the Series B Preferred Stock in order to preserve the status of the Company as a REIT for United States federal income tax purposes, such redemption shall be made in accordance with the terms and conditions set forth in this Section 5
of these Articles Supplementary. If the Company calls for redemption any shares of Series B Preferred Stock pursuant to and in accordance with this Section 5(c), then the redemption price for such shares will be an amount in cash equal to $25.00 per
share together with all accrued and unpaid dividends to but excluding the dated fixed for redemption. 
 (d) Unless full
cumulative dividends on all Series B Preferred Stock shall have been or contemporaneously are authorized, declared and paid in cash, or declared and a sum sufficient for the payment thereof in cash set apart for payment for all past dividend
periods, no shares of Series B Preferred Stock shall be redeemed unless all 

  
 4 

 
outstanding shares of Series B Preferred Stock are simultaneously redeemed, and the Company shall not purchase or otherwise acquire directly or indirectly any shares of Series B Preferred Stock
or any class or series of capital stock of the Company ranking, as to dividends or upon liquidation, on parity with or junior to the Series B Preferred Stock (except by exchange for shares of capital stock of the Company ranking, as to dividends and
upon liquidation, junior to the Series B Preferred Stock); provided, however, that the foregoing shall not prevent the purchase of Series B Preferred Stock by the Company in accordance with the terms of Sections 5(c) and 7 of these
Articles Supplementary or otherwise in order to ensure that the Company remains qualified as a REIT for United States federal income tax purposes, or the purchase or acquisition of Series B Preferred Stock pursuant to a purchase or exchange offer
made on the same terms to holders of all outstanding shares of Series B Preferred Stock. 
 (e) Notice of redemption will be
given by publication in a newspaper of general circulation in the City of New York, such publication to be made once a week for two successive weeks commencing not fewer than 30 or more than 60 days prior to the redemption date. A similar notice
will be mailed by the Company, postage prepaid, not fewer than 30 or more than 60 days prior to the redemption date, addressed to the respective holders of record of the Series B Preferred Stock to be redeemed at their respective addresses as they
appear on the transfer records of the Company. No failure to give or defect in such notice shall affect the validity of the proceedings for the redemption of any Series B Preferred Stock except as to the holder to whom such notice was defective or
not given. In addition to any information required by law or by the applicable rules of any exchange upon which the Series B Preferred Stock may be listed or admitted to trading, each such notice shall state: (i) the redemption date, (ii) the
redemption price, (iii) the number of shares of Series B Preferred Stock to be redeemed, (iv) the place or places where the certificates representing shares of Series B Preferred Stock are to be surrendered for payment of the redemption price, (v)
that dividends on the shares of Series B Preferred Stock to be redeemed will cease to accumulate on such redemption date and (vi) that payment of the redemption price and any accumulated and unpaid dividends will be made upon presentation and
surrender of such Series B Preferred Stock. If fewer than all of the shares of Series B Preferred Stock held by any holder are to be redeemed, the notice mailed to such holder shall also specify the number of shares of Series B Preferred Stock held
by such holder to be redeemed. Notwithstanding anything else to the contrary in these Articles Supplementary, the Company shall not be required to provide notice to the holder of Series B Preferred Stock in the event such holder’s Series B
Preferred Stock is redeemed in accordance with Section 7 of these Articles Supplementary to preserve the Company’s status as a REIT. 
 (f) If a redemption date falls after a Dividend Record Date and on or prior to the corresponding Dividend Payment Date, each holder of Series B Preferred Stock at the close of business of such Dividend
Record Date shall be entitled to the dividend payable on such shares on the corresponding Dividend Payment Date notwithstanding the redemption of such shares on or prior to such Dividend Payment Date, and each holder of Series B Preferred Stock that
surrenders its shares on such redemption date will be entitled to the dividends accruing after the end of the Dividend Period to which such Dividend Payment Date relates up to but excluding the redemption date. Except as provided herein, the Company
shall make no payment or allowance for unpaid dividends, whether or not in arrears, on Series B Preferred Stock for which a notice of redemption has been given. 
 (g) All shares of the Series B Preferred Stock redeemed or repurchased pursuant to this Section 5 shall be retired and shall be restored to the status of authorized but unissued shares of Preferred Stock,
without designation as to series or class. 
 (h) The Series B Preferred Stock shall have no stated maturity and shall not be
subject to any sinking fund or mandatory redemption; provided, however, that the Series B Preferred Stock owned by a stockholder in excess of the Ownership Limit shall be subject to the provisions of this Section 5 and Section 7 of
these Articles Supplementary. 
 Section 6. Voting Rights. 

(a) Holders of the Series B Preferred Stock shall not have any voting rights, except as set forth in this Section 6. 

(b) Whenever dividends on any shares of Series B Preferred Stock shall be in arrears for six or more consecutive or non-consecutive
quarterly periods (a “Preferred Dividend Default”), the holders of such Series B Preferred Stock (voting as a single class with all other classes or series of preferred stock of the Company upon

  
 5 

 
which like voting rights have been conferred and are exercisable (“Parity Preferred”), including the Series A Cumulative Redeemable Preferred Stock of the Company) shall be
entitled to vote for the election of a total of two additional directors of the Company (the “Preferred Directors”) until all dividends accumulated on such Series B Preferred Stock and Parity Preferred for the past dividend periods
shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for payment. In such case, the entire Board of Directors will be increased by two directors. 

(c) The Preferred Directors will be elected by a plurality of the votes cast in the election for a one-year term and each Preferred
Director will serve until his or her successor is duly elected and qualified or until such Preferred Director’s right to hold the office terminates, whichever occurs earlier, subject to such Preferred Director’s earlier death,
disqualification, resignation or removal. The election will take place at (i) either (A) a special meeting called in accordance with Section 6(d) below if the request is received more than 90 days before the date fixed for the Company’s next
annual or special meeting of stockholders or (B) the next annual or special meeting of stockholders if the request is received within 90 days of the date fixed for the Company’s next annual or special meeting of stockholders, and (ii) at each
subsequent annual meeting of stockholders, or special meeting held in place thereof, until all such dividends in arrears on the Series B Preferred Stock and each such class or series of outstanding Parity Preferred have been paid in full. A dividend
in respect of Series B Preferred Stock shall be considered timely made if made within two Business Days after the applicable Dividend Payment Date if at the time of such late payment date there shall not be any prior quarterly dividend periods in
respect of which full dividends were not timely made at the applicable Dividend Payment Date. 
 (d) At any time when such
voting rights shall have vested, a proper officer of the Company shall call or cause to be called, upon written request of holders of record of at least 10% of the outstanding shares of Series B Preferred Stock and Parity Preferred, a special
meeting of the holders of Series B Preferred Stock and each class or series of Parity Preferred by mailing or causing to be mailed to such holders a notice of such special meeting to be held not fewer than ten or more than 45 days after the date
such notice is given. The record date for determining holders of the Series B Preferred Stock and Parity Preferred entitled to notice of and to vote at such special meeting will be the close of business on the third Business Day preceding the day on
which such notice is mailed. At any such annual or special meeting, all of the holders of the Series B Preferred Stock and Parity Preferred, by plurality vote, voting together as a single class without regard to class or series will be entitled to
elect two directors on the basis of one vote per $25.00 of liquidation preference to which such Series B Preferred Stock and Parity Preferred are entitled by their terms (excluding amounts in respect of accumulated and unpaid dividends) and not
cumulatively. The holder or holders of one-third of the Series B Preferred stock and Parity Preferred voting as a single class then outstanding, present in person or by proxy, will constitute a quorum for the election of the Preferred Directors
except as otherwise provided by law. Notice of all meetings at which holders of the Series B Preferred Stock and the Parity Preferred shall be entitled to vote will be given to such holders at their addresses as they appear in the transfer records.
At any such meeting or adjournment thereof in the absence of a quorum, subject to the provisions of any applicable law, a majority of the holders of the Series B Preferred and Parity Preferred voting as a single class present in person or by proxy
shall have the power to adjourn the meeting for the election of the Preferred Directors, without notice other than an announcement at the meeting, until a quorum is present. If a Preferred Dividend Default shall terminate after the notice of a
special meeting has been given but before such special meeting has been held, the Company shall, as soon as practicable after such termination, mail or cause to be mailed notice of such termination to holders of the Series B Preferred Stock and the
Parity Preferred that would have been entitled to vote at such special meeting. 
 (e) If and when all accumulated dividends on
such Series B Preferred Stock and all classes or series of Parity Preferred for the past dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for payment, the right of the holders of Series B
Preferred Stock and the Parity Preferred to elect such additional two directors shall immediately cease (subject to revesting in the event of each and every Preferred Dividend Default), and the term of office of each Preferred Director so elected
shall terminate and the entire Board of Directors shall be reduced accordingly. Any Preferred Director may be removed at any time with or without cause by the vote of, and shall not be removed otherwise than by the vote of, the holders of record of
a majority of the outstanding Series B Preferred Stock and the Parity Preferred entitled to vote thereon when they have the voting rights set forth in Section 6(b) (voting as a single class). So long as a Preferred Dividend Default shall continue,
any vacancy in the office of a Preferred Director may be filled by written consent of the Preferred Director remaining in office, or if none remains in office, by a vote of the holders of record of a majority of the outstanding Series B Preferred
Stock when they have the voting rights described above (voting as a single class with all other classes or series of Parity Preferred). Each of the Preferred Directors shall be entitled to one vote on any matter. 

  
 6 

 (f) So long as any shares of Series B Preferred Stock remain outstanding, the affirmative
vote or consent of the holders of two-thirds of the shares of Series B Preferred Stock and each other class or series of preferred stock ranking on parity with the Series B Preferred Stock with respect to the payment of dividends and the
distribution of assets upon liquidation, dissolution or winding up of the Company upon which like voting rights have been conferred outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting as a single class)
will be required to: (i) authorize, create or issue, or increase the authorized or issued amount of, any class or series of capital stock ranking senior to the Series B Preferred Stock with respect to payment of dividends or the distribution of
assets upon liquidation, dissolution or winding up of the affairs of the Company or reclassify any authorized shares of capital stock of the Company into such capital stock, or create, authorize or issue any obligation or security convertible into
or evidencing the right to purchase any such capital stock; or (ii) amend, alter or repeal the provisions of the Charter or the terms of the Series B Preferred Stock, whether by merger, consolidation, transfer or conveyance of all or substantially
all of its assets or otherwise (an “Event”), so as to materially and adversely affect any right, preference, privilege or voting power of the Series B Preferred Stock; provided however, with respect to the occurrence
of any of the Events set forth in (ii) above, so long as the Series B Preferred Stock remains outstanding with the terms thereof materially unchanged, taking into account that, upon the occurrence of an Event, the Company may not be the surviving
entity, the occurrence of such Event shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting power of Series B Preferred Stock, and in such case such holders shall not have any voting rights with respect
to the occurrence of any of the Events set forth in (ii) above. In addition, if the holders of the Series B Preferred Stock receive the greater of the full trading price of the Series B Preferred Stock on the date of an Event set forth in (ii) above
or the $25.00 liquidation preference per share of the Series B Preferred Stock pursuant to the occurrence of any of the Events set forth in (ii) above, then such holders shall not have any voting rights with respect to the Events set forth in (ii)
above. Holders of shares of Series B Preferred Stock shall not be entitled to vote with respect to (A) any increase in the total number of authorized shares of Common Stock or Preferred Stock of the Company, or (B) any increase in the amount of the
authorized Series B Preferred Stock or the creation or issuance of any other class or series of capital stock, or (C) any increase in the number of authorized shares of any other class or series of capital stock, in each case referred to in clause
(A), (B) or (C) above ranking on parity with or junior to the Series B Preferred Stock with respect to the payment of dividends and the distribution of assets upon liquidation, dissolution or winding up of the Company. Except as set forth herein,
holders of the Series B Preferred Stock shall not have any voting rights with respect to, and the consent of the holders of the Series B Preferred Stock shall not be required for, the taking of any corporate action, including an Event, regardless of
the effect that such corporate action or Event may have upon the powers, preferences, voting power or other rights or privileges of the Series B Preferred Stock. 
 (g) The foregoing voting provisions of this Section 6 shall not apply if, at or prior to the time when the act with respect to which such vote would otherwise be required shall be effected, all
outstanding shares of Series B Preferred Stock shall have been redeemed or called for redemption upon proper notice and sufficient funds, in cash, shall have been deposited in trust to effect such redemption. 

(h) In any matter in which the Series B Preferred Stock may vote (as expressly provided herein), each share of Series B Preferred Stock
shall be entitled to one vote per $25.00 of liquidation preference.

 (c)
Transfers of Series B Preferred Stock in Trust. 
 (i) Upon any purported Transfer or other event described in Section

 (iii) The Trustee shall have all voting rights and rights to dividends with respect to Series B Preferred Stock held in the
Trust, which rights shall be exercised for the exclusive benefit of the Charitable Beneficiary. Any dividend or distribution paid to or on behalf of the Purported Record Transferee or Purported Beneficial Transferee prior to the discovery by the
Company that shares of Series B Preferred Stock have been transferred to the Trustee shall be paid to the Trustee upon demand, and any dividend or distribution declared but unpaid shall be paid when due to the Trustee with respect to such Series B
Preferred Stock. Any dividends or distributions so paid over to the Trustee shall be held in trust for the Charitable Beneficiary. The Purported Record Transferee and Purported Beneficial Transferee shall have no voting rights with respect to the
Series B Preferred Stock held in the Trust and, subject to Maryland law, effective as of the date the Series B Preferred Stock has been transferred to the Trustee, the Trustee shall have the authority (at the Trustee’s sole discretion) (i) to
rescind as void any vote cast by a Purported Record Transferee with respect to such Series B Preferred Stock prior to the discovery by the Company that the Series B Preferred Stock has been transferred to the Trustee and (ii) to recast such vote in
accordance with the desires of the Trustee acting for the benefit of the Charitable Beneficiary; provided, however, that if the Company has already taken irreversible corporate action, then the Trustee shall not have the authority to rescind
and recast such vote. Notwithstanding any other provision of these Articles Supplementary to the contrary, until the Company has received notification that the Series B Preferred Stock has been transferred into a Trust, the Company shall be entitled
to rely on its share transfer and other stockholder records for purposes of preparing lists of stockholders entitled to vote at meetings, determining the validity and authority of proxies and otherwise conducting votes of stockholders. 

(iv) Within twenty (20) days of receiving notice from the Company that shares of Series B Preferred Stock have been transferred to the
Trust, the Trustee of the Trust shall sell the shares of Series B Preferred Stock held in the Trust to a Person, designated by the Trustee, whose ownership of the shares of Series B Preferred Stock will not violate the ownership limitations set
forth in Section 7(b)(i). Upon such sale, the interest of the Charitable Beneficiary in the shares of Series B Preferred Stock sold shall terminate and the Trustee shall distribute 

  
 10 

 
the net proceeds of the sale to the Purported Record Transferee and to the Charitable Beneficiary as provided in this Section 7(c)(iv). The Purported Record Transferee shall receive the lesser of
(i) the price paid by the Purported Record Transferee for the shares of Series B Preferred Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase
of such shares of Series B Preferred Stock at Market Price, the Market Price of such shares of Series B Preferred Stock on the day of the event which resulted in the transfer of such shares of Series B Preferred Stock to the Trust) and (ii) the
price per share received by the Trustee (net of any commissions and other expenses of sale) from the sale or other disposition of the shares of Series B Preferred Stock held in the Trust. The Trustee may reduce the amount payable to the Purported
Record Transferee by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 7(c)(iii). Any net sales proceeds in excess of
the amount payable to the Purported Record Transferee shall be immediately paid to the Charitable Beneficiary together with any dividends or other distributions thereon. If, prior to the discovery by the Company that shares of such Series B
Preferred Stock have been transferred to the Trustee, such shares of Series B Preferred Stock are sold by a Purported Record Transferee then (i) such shares of Series B Preferred Stock shall be deemed to have been sold on behalf of the Trust and
(ii) to the extent that the Purported Record Transferee received an amount for such shares of Series B Preferred Stock that exceeds the amount that such Purported Record Transferee was entitled to receive pursuant to this Section 7(c)(iv), such
excess shall be paid to the Trustee upon demand. 
 (v) Series B Preferred Stock transferred to the Trustee shall be deemed to
have been offered for sale to the Company, or its designee, at a price per share equal to the lesser of (i) the price paid by the Purported Record Transferee for the shares of Series B Preferred Stock in the transaction that resulted in such
transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Series B Preferred Stock at Market Price, the Market Price of such shares of Series B Preferred Stock on the day of the
event which resulted in the transfer of such shares of Series B Preferred Stock to the Trust) and (ii) the Market Price on the date the Company, or its designee, accepts such offer. The Company may reduce the amount payable to the Purported Record
Transferee by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 7(c)(iii). The Company shall have the right to accept
such offer until the Trustee has sold the shares of Series B Preferred Stock held in the Trust pursuant to Section 7(c)(iv). Upon such a sale to the Company, the interest of the Charitable Beneficiary in the shares of Series B Preferred Stock sold
shall terminate and the Trustee shall distribute the net proceeds of the sale to the Purported Record Transferee and any dividends or other distributions held by the Trustee with respect to such Series B Preferred Stock shall thereupon be paid to
the Charitable Beneficiary. 
 (vi) By written notice to the Trustee, the Company shall designate one or more nonprofit
organizations to be the Charitable Beneficiary of the interest in the Trust such that the Series B Preferred Stock held in the Trust would not violate the restrictions set forth in Section 7(b)(i) in the hands of such Charitable Beneficiary.

 (d) Remedies For Breach. If the Board of Directors or a committee thereof or other designees if permitted by the MGCL
shall at any time determine in good faith that a Transfer or other event has taken place in violation of Section 7(b) of these Articles Supplementary or that a Person intends to acquire, has attempted to acquire or may acquire beneficial ownership
(determined without reference to any rules of attribution), Beneficial Ownership or Constructive Ownership of any shares of Series B Preferred Stock of the Company in violation of Section 7(b) of these Articles Supplementary, the Board of Directors
or the Committee or other designees if permitted by the MGCL shall take such action as it deems advisable to refuse to give effect or to prevent such Transfer, including, but not limited to, causing the Company to redeem shares of Series B Preferred
Stock, refusing to give effect to such Transfer on the books of the Company or instituting proceedings to enjoin such Transfer; provided, however, that any Transfers (or, in the case of events other than a Transfer, ownership or Constructive
Ownership or Beneficial Ownership) in violation of Section 7(b)(i) of these Articles Supplementary, shall automatically result in the transfer to a Trust as described in Section 7(b)(ii) and any Transfer in violation of Section 7(b)(iii) shall
automatically be void ab initio irrespective of any action (or non-action) by the Board of Directors. 
 (e) Notice of
Restricted Transfer. Any Person who acquires or attempts to acquire shares of Series B Preferred Stock in violation of Section 7(b) of these Articles Supplementary, or any Person who is a Purported Beneficial Transferee such that an automatic
transfer to a Trust results under Section 7(b)(ii) of these Articles Supplementary, shall immediately give written notice to the Company of such event and shall provide to the Company such other information as the Company may request in order to
determine the effect, if any of such Transfer or attempted Transfer on the Company’s status as a REIT. 

  
 11 

 (f) Owners Required To Provide Information. Prior to the Restriction Termination Date
each Person who is a beneficial owner or Beneficial Owner or Constructive Owner of Series B Preferred Stock and each Person (including the stockholder of record) who is holding Series B Preferred Stock for a beneficial owner or Beneficial Owner or
Constructive Owner shall provide to the Company such information that the Company may request, in good faith, in order to determine the Company’s status as a REIT. 
 (g) Remedies Not Limited. Nothing contained in these Articles Supplementary (but subject to Section 7(l) of these Articles Supplementary) shall limit the authority of the Board of Directors to take
such other action as it deems necessary or advisable to protect the Company and the interests of its stockholders by preservation of the Company’s status as a REIT. 
 (h) Ambiguity. In the case of an ambiguity in the application of any of the provisions of this Section 7 of these Articles Supplementary, including any definition contained in Section 7(a), the
Board of Directors shall have the power to determine the application of the provisions of this Section 7 with respect to any situation based on the facts known to it (subject, however, to the provisions of Section 7(l) of these Articles
Supplementary). In the event Section 7 requires an action by the Board of Directors and these Articles Supplementary fail to provide specific guidance with respect to such action, the Board of Directors shall have the power to determine the action
to be taken so long as such action is not contrary to the provisions of Section 7. Absent a decision to the contrary by the Board of Directors (which the Board of Directors may make in its sole and absolute discretion), if a Person would have (but
for the remedies set forth in Section 7(b)) acquired Beneficial or Constructive Ownership of Series B Preferred Stock in violation of Section 7(b)(i), such remedies (as applicable) shall apply first to the shares of Series B Preferred Stock which,
but for such remedies, would have been actually owned by such Person, and second to shares of Series B Preferred Stock, which, but for such remedies, would have been Beneficially Owned or Constructively Owned (but not actually owned) by such Person,
pro rata among the Persons who actually own such shares of Series B Preferred Stock based upon the relative number of the shares of Series B Preferred Stock held by each such Person. 

(i) Exceptions. 
 (i) Subject to Section 7(b)(i)(C), the Board of Directors, in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Beneficially Owning shares of Series
B Preferred Stock in violation of Section 7(b)(i)(A) if the Board of Directors determines that such exemption will not cause any Individual’s Beneficial Ownership of shares of Capital Stock to violate the Aggregate Stock Ownership Limit and
that such exemption will not cause the Company to fail to qualify as a REIT under the Code. 
 (ii) Subject to Section
7(b)(i)(C), the Board of Directors in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Constructively Owning Series B Preferred Stock in violation of Section 7(b)(i)(B), if the Board of
Directors determines that such ownership would not cause the Company to fail to qualify as a REIT under the Code. 
 (iii)
Subject to Section 7(b)(i)(C) and the remainder of this Section 7(i)(iii), the Board of Directors may from time to time increase or decrease the Ownership Limit; provided, however, that the decreased Ownership Limit will not be
effective for any Person whose percentage ownership of Series B Preferred Stock is in excess of such decreased Ownership Limit until such time as such Person’s percentage of Series B Preferred Stock equals or falls below the decreased Ownership
Limit, but any further acquisition of Series B Preferred Stock in excess of such percentage ownership of Series B Preferred Stock will be in violation of the Ownership Limit, and, provided further, that the new Ownership Limit would not allow five
or fewer Persons to Beneficially Own more than 49% in value of the outstanding capital stock of the Company. 
 (iv) In granting
a person an exemption under Section 7(i)(i) or (ii) above, the Board of Directors may require such Person to make certain representations or undertakings or to agree that any violation or attempted violation of such representations or undertakings
(or other action which is contrary to the restrictions contained in Section 7(b) of these Articles Supplementary) will result in such Series B Preferred Stock being 

  
 12 

 
transferred to a Trust in accordance with Section 7(b)(ii) of these Articles Supplementary. In granting any exception pursuant to Section 7(i)(i) or (ii) of these Articles Supplementary, the
Board of Directors may require a ruling from the IRS, or an opinion of counsel, in either case in form and substance satisfactory to the Board of Directors in its sole discretion, as it may deem necessary or advisable in order to determine or ensure
the Company’s status as a REIT.

SECTION 1. Designation and Number. A series of Preferred Stock, designated the “4.375% Series C Cumulative
Convertible Preferred Stock” (the “Series C Preferred Stock”), is hereby established. The number of shares of Series C Preferred Stock shall be 8,050,000. 

SECTION 2. Rank. The Series C Preferred Stock will, with respect to dividend rights and rights upon voluntary or involuntary
liquidation, dissolution or winding up of the Company, rank: (i) senior to all classes or series of the Company’s common stock, par value $.01 per share (the “Common Stock”), and all classes or series of capital stock of
the Company now or hereafter authorized, issued or outstanding expressly designated as ranking junior to the Series C Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the
Company; (ii) on parity with the Series A Cumulative Redeemable Preferred Stock, par value $0.01 per share, and the Series B Cumulative Redeemable Preferred Stock, par value $0.01 per share, of the Company and with any class or series of
capital stock of the Company expressly designated as ranking on parity 

 
with the Series C Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company; and (iii) junior to any class or
series of capital stock of the Company expressly designated as ranking senior to the Series C Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company. The term
“capital stock” does not include convertible or exchangeable debt securities, which will rank senior to the Series C Preferred Stock prior to conversion or exchange. The Series C Preferred Stock will rank junior in right of payment
to the Company’s other existing and future debt obligations. 
 SECTION 3. Dividends. 

 (a) Subject to the preferential rights of the holders of any class or series of capital stock of the Company ranking senior to
the Series C Preferred Stock as to dividends, the holders of shares of the Series C Preferred Stock shall be entitled to receive, when, as and if authorized by the Board of Directors and declared by the Company, out of funds legally available for
the payment of dividends, cumulative cash dividends at the rate of 4.375% per annum of the $25.00 liquidation preference per share of the Series C Preferred Stock (equivalent to the fixed annual amount of $1.09375 per share of the Series C
Preferred Stock). Such dividends shall accrue and be cumulative from and including the first date on which any shares of Series C Preferred Stock are issued (the “Original Issue Date”) and shall be payable quarterly in arrears on
each Dividend Payment Date (as defined below), commencing June 30, 2007; provided, however, that if any Dividend Payment Date is not a Business Day (as defined below), then the dividend which would otherwise have been payable on
such Dividend Payment Date may be paid on the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case 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. The amount of any dividend
payable on the Series C Preferred Stock for any partial Dividend Period (as defined below) shall be prorated and computed on the basis of a 360-day year consisting of twelve
30-day months. Dividends will be payable to holders of record as they appear in the stockholder records of the Company at the close of business on the applicable Dividend Record Date (as defined below).
Notwithstanding any provision to the contrary contained herein, each outstanding share of Series C Preferred Stock shall be entitled to receive a dividend with respect to any Dividend Record Date equal to the dividend paid with respect to each other
share of Series C Preferred Stock that is outstanding on such date. “Dividend Record Date” shall mean the date designated by the Board of Directors for the payment of dividends that is not more than 35 or fewer than 10 days prior to
the applicable Dividend Payment Date. “Dividend Payment Date” shall mean the last calendar day of each March, June, September and December, commencing on June 30, 2007. “Dividend Period” shall mean the
respective periods commencing on and including the first day of January, April, July and October of each year and ending on and including the day preceding the first day of the next succeeding Dividend Period (other than the initial Dividend Period,
which shall commence on the Original Issue Date and end on and include June 30, 2007, and other than the Dividend Period during which any shares of Series C Preferred Stock shall be redeemed pursuant to Section 5, which shall end on and
include the day preceding the call date with respect to the shares of Series C Preferred Stock being redeemed). 
 The term
“Business Day” shall mean each day, other than a Saturday or a Sunday, which is not a day on which banking institutions in New York, New York are authorized or required by law, regulation or executive order to close. 

(b) Notwithstanding anything contained herein to the contrary, dividends on the Series C Preferred Stock shall accrue whether or not the
Company has earnings, whether or not there are funds legally available for the payment of such dividends, and whether or not such dividends are authorized or declared. 
 (c) Except as provided in Section 3(d) below, no dividends shall be declared or paid or set apart for payment, and no other distribution of cash or other property may be declared or made, directly or
indirectly, on or with respect to, any shares of Common Stock or shares of any other class or series of capital stock of the Company ranking, as to dividends, on parity with or junior to the Series C Preferred Stock (other than a dividend paid in
shares of Common Stock or in shares of any other class or series of capital stock ranking junior to the Series C Preferred Stock as to dividends and upon liquidation) for any period, nor shall any shares of Common Stock or any other shares of any
other class or series of capital stock of the Company ranking, as to dividends or upon liquidation, on parity with or junior to the Series C Preferred Stock be redeemed, purchased or otherwise acquired for any consideration, nor shall any funds be
paid or made available for a sinking fund for the redemption of such shares, 

 
and no other distribution of cash or other property may be made, directly or indirectly, on or with respect thereto by the Company (except by conversion into or exchange for other shares of any
class or series of capital stock of the Company ranking junior to the Series C Preferred Stock as to dividends and upon liquidation, and except for the acquisition of shares made pursuant to the provisions of Article VI of the Charter or
Section 7 hereof), unless full cumulative dividends on the Series C Preferred Stock for all past dividend periods shall have been or contemporaneously are (i) declared and paid in cash or (ii) declared and a sum sufficient for the
payment thereof in cash is set apart for such payment. 
 (d) When dividends are not paid in full (and a sum sufficient for such
full payment is not so set apart) upon the Series C Preferred Stock and the shares of any other class or series of capital stock ranking, as to dividends, on parity with the Series C Preferred Stock, all dividends declared upon the Series C
Preferred Stock and each such other class or series of capital stock ranking, as to dividends, on parity with the Series C Preferred Stock shall be declared pro rata so that the amount of dividends declared per share of Series C Preferred Stock and
such other class or series of capital stock shall in all cases bear to each other the same ratio that accrued dividends per share on the Series C Preferred Stock and such other class or series of capital stock (which shall not include any accrual in
respect of unpaid dividends on such other class or series of capital stock for prior dividend periods if such other class or series of capital stock does not have a cumulative dividend) bear to each other. No interest, or sum of money in lieu of
interest, shall be payable in respect of any dividend payment or payments on the Series C Preferred Stock which may be in arrears. 
 (e) Holders of shares of Series C Preferred Stock shall not be entitled to any dividend, whether payable in cash, property or shares of stock, in excess of full cumulative dividends on the Series C
Preferred Stock as provided herein. Any dividend payment made on the Series C Preferred Stock shall first be credited against the earliest accrued but unpaid dividends due with respect to such shares which remains payable. Accrued but unpaid
distributions on the Series C Preferred Stock will accumulate as of the Dividend Payment Date on which they first become payable. 
 SECTION 4. Liquidation Preference. 
 (a) Upon any voluntary or
involuntary liquidation, dissolution or winding up of the affairs of the Company, before any distribution or payment shall be made to holders of shares of Common Stock or any other class or series of capital stock of the Company ranking, as to
rights upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, junior to the Series C Preferred Stock, the holders of shares of Series C Preferred Stock shall be entitled to be paid out of the assets
of the Company legally available for distribution to its stockholders, after payment of or provision for the debts and other liabilities of the Company, a liquidation preference of $25.00 per share, plus an amount equal to any accrued and unpaid
dividends (whether or not authorized or declared) to but excluding the date of payment. In the event that, upon such voluntary or involuntary liquidation, dissolution or winding up, the available assets of the Company are insufficient to pay the
full amount of the liquidating distributions on all outstanding shares of Series C Preferred Stock and the corresponding amounts payable on all shares of other classes or series of capital stock of the Company ranking, as to liquidation rights, on
parity with the Series C Preferred Stock in the distribution of assets, then the holders of the Series C Preferred Stock and each such other class or series of shares of capital stock ranking, as to voluntary or involuntary liquidation rights, on
parity with the Series C Preferred Stock shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled. Written notice of any such voluntary or
involuntary liquidation, dissolution or winding up of the Company, stating the payment date or dates when, and the place or places where, the amounts distributable in such circumstances shall be payable, shall be given by first class mail, postage pre-paid, not fewer than 30 or more than 60 days prior to the payment date stated therein, to each record holder of shares of Series C Preferred Stock at the respective addresses of such holders as the same shall
appear on the stock transfer records of the Company. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of Series C Preferred Stock will have no right or claim to any of the remaining assets of
the Company. The consolidation or merger of the Company with or into any other corporation, trust or entity, or the voluntary sale, lease, transfer or conveyance of all or substantially all of the property or business of the Company, shall not be
deemed to constitute a liquidation, dissolution or winding up of the affairs of the Company. 
 (b) In determining whether a
distribution (other than upon voluntary or involuntary liquidation), by dividend, redemption or other acquisition of shares of capital stock of the Company or otherwise, is permitted under 

 
the MGCL, amounts that would be needed, if the Company were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of holders of shares of Series C
Preferred Stock shall not be added to the Company’s total liabilities. 
 SECTION 5. Redemption. 

(a) The Company shall have the right to redeem shares of the Series C Preferred Stock in order to preserve the Company’s status as a
REIT for federal tax purposes, in whole or in part, at any time or from time to time, for cash at a redemption price equal to 100% of the liquidation preference of the Series C Preferred Stock to be redeemed plus an amount equal to all accrued and
unpaid dividends up to, but not including, the date fixed for redemption, without interest; provided that if the redemption date is on a date that is after a Dividend Record Date and on or prior to the corresponding Dividend Payment Date, the
Company shall pay such dividends to the holder of record of such shares of Series C Preferred Stock on the Dividend Record Date, and the redemption price shall be equal to 100% of the liquidation preference of the Series C Preferred Stock to be
redeemed. 
 (b) If fewer than all of the outstanding shares of Series C Preferred Stock are to be redeemed, the shares of
Series C Preferred Stock to be redeemed shall be redeemed pro rata (as nearly as may be practicable without creating fractional shares) by lot or by any other equitable method determined by the Company that will not result in a violation of the
Ownership Limit and the Aggregate Stock Ownership Limit (each, as defined in Section 7(a)). If redemption is to be by lot and, as a result, any holder of shares of Series C Preferred Stock would have actual ownership, Beneficial Ownership or
Constructive Ownership (each, as defined in Section 7(a)) in excess of the Ownership Limit (as defined in Section 7(a)), the Aggregate Stock Ownership Limit or such other limit as permitted by the Board of Directors or the Committee
pursuant to Section 7(i) because such holder’s shares of Series C Preferred Stock were not redeemed, or were only redeemed in part, then, except as otherwise provided in the Charter, the Company shall redeem the requisite number of shares
of Series C Preferred Stock of such holder such that no holder will hold an amount of Series C Preferred Stock in excess of the applicable ownership limit subsequent to such redemption. Holders of Series C Preferred Stock to be redeemed shall
surrender such Series C Preferred Stock at the place designated in such notice and shall be entitled to the redemption price of $25.00 per share and any accrued and unpaid dividends payable upon such redemption following such surrender. If
(i) notice of redemption of any shares of Series C Preferred Stock has been given, (ii) the funds necessary for such redemption have been set aside by the Company in trust for the benefit of the holders of any shares of Series C Preferred
Stock so called for redemption, and (iii) irrevocable instructions have been given to pay the redemption price and all accrued and unpaid dividends, then from and after the redemption date, dividends shall cease to accrue on such shares of
Series C Preferred Stock, such shares of Series C Preferred Stock shall no longer be deemed outstanding, and all rights of the holders of such shares shall terminate, except the right to receive the redemption price plus any accrued and unpaid
dividends payable upon such redemption, without interest. So long as no dividends are in arrears, nothing herein shall prevent or restrict the Company’s right or ability to purchase, from time to time, either at a public or a private sale, all
or any part of the Series C Preferred Stock at such price or prices as the Company may determine, subject to the provisions of applicable law, including the repurchase of shares of Series C Preferred Stock in open-market transactions duly authorized
by the Board of Directors. 
 (c) [Intentionally Omitted.] 

(d) [Intentionally Omitted.] 
 (e) [Intentionally Omitted.] 
 (f) If a redemption date falls after a Dividend
Record Date and on or prior to the corresponding Dividend Payment Date, each holder of Series C Preferred Stock at the close of business on such Dividend Record Date shall be entitled to the dividend payable on such shares on the corresponding
Dividend Payment Date notwithstanding the redemption of such shares on or prior to such Dividend Payment Date, and each holder of Series C Preferred Stock that surrenders its shares on such redemption date will be entitled to the dividends accruing
after the end of the Dividend Period to which such Dividend Payment Date relates up to but excluding the redemption date. Except as provided herein, the Company shall make no payment or allowance for unpaid dividends, whether or not in arrears, on
Series C Preferred Stock for which a notice of redemption has been given. 

 (g) All shares of the Series C Preferred Stock redeemed or repurchased pursuant to this
Section 5 shall be retired and shall be restored to the status of authorized but unissued shares of Preferred Stock, without designation as to series or class. 
 (h) The Series C Preferred Stock shall have no stated maturity and shall not be subject to any sinking fund or mandatory redemption; provided, however, that the Series C Preferred Stock
owned by a stockholder in excess of the Ownership Limit shall be subject to the provisions of this Section 5 and Section 7 of these Articles Supplementary. 
 SECTION 6. Voting Rights. 
 (a) Holders of the Series C Preferred Stock
shall not have any voting rights, except as set forth in this Section 6. 
 (b) Whenever dividends on any shares of Series
C Preferred Stock shall be in arrears for six or more consecutive or non-consecutive quarterly periods (a “Preferred Dividend Default”), the holders of such Series C Preferred Stock (voting
together as a single class with all other classes or series of preferred stock of the Company upon which like voting rights have been conferred and are exercisable (“Parity Preferred”), including the Series A Cumulative Redeemable
Preferred Stock and the Series B Cumulative Redeemable Preferred Stock of the Company) shall be entitled to vote for the election of a total of two additional directors of the Company (the “Preferred Directors”) until all dividends
accumulated on such Series C Preferred Stock and Parity Preferred for the past dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for payment. In such case, the entire Board of Directors
will be increased by two directors. 
 (c) The Preferred Directors will be elected by a plurality of the votes cast in the
election for a one-year term and each Preferred Director will serve until his or her successor is duly elected and qualified or until such Preferred Director’s right to hold the office terminates,
whichever occurs earlier, subject to such Preferred Director’s earlier death, disqualification or removal. The election will take place at (i) either (a) a special meeting called in accordance with Section 6(d) below if the
request is received more than 90 days before the date fixed for the Company’s next annual or special meeting of stockholders or (b) the next annual or special meeting of stockholders if the request is received within 90 days of the date
fixed for the Company’s next annual or special meeting of stockholders, and (ii) at each subsequent annual meeting of stockholders, or special meeting held in place thereof, until all such dividends in arrears on the Series C Preferred
Stock and each such class or series of outstanding Parity Preferred have been paid in full. A dividend in respect of Series C Preferred Stock shall be considered timely made if made within two Business Days after the applicable Dividend Payment Date
if at the time of such late payment date there shall not be any prior quarterly dividend periods in respect of which full dividends were not timely made at the applicable Dividend Payment Date. 

(d) At any time when such voting rights shall have vested, a proper officer of the Company shall call or cause to be called, upon written
request of holders of record of at least 10% of the outstanding shares of Series C Preferred Stock and Parity Preferred, a special meeting of the holders of Series C Preferred Stock and each class or series of Parity Preferred by mailing or causing
to be mailed to such holders a notice of such special meeting to be held not fewer than ten or more than 45 days after the date such notice is given. The record date for determining holders of the Series C Preferred Stock and Parity Preferred
entitled to notice of and to vote at such special meeting will be the close of business on the third Business Day preceding the day on which such notice is mailed. At any such annual or special meeting, all of the holders of the Series C Preferred
Stock and Parity Preferred, by plurality vote, voting together as a single class without regard to class or series will be entitled to elect two directors on the basis of one vote per $25.00 of liquidation preference to which such Series C Preferred
Stock and Parity Preferred are entitled by their terms (excluding amounts in respect of accumulated and unpaid dividends) and not cumulatively. The holder or holders of one-third of the Series C Preferred
Stock and Parity Preferred voting as a single class then outstanding, present in person or by proxy, will constitute a quorum for the election of the Preferred Directors except as otherwise provided by law. Notice of all meetings at which holders of
the Series C Preferred Stock and the Parity Preferred shall be entitled to vote will be given to such holders at their addresses as they appear in the transfer records. At any such meeting or adjournment thereof in the absence of a quorum, subject
to the provisions of any applicable law, a majority of the holders of the Series C Preferred Stock and Parity Preferred voting as a single class present in person or by proxy shall have the power to adjourn the meeting for the election of the
Preferred Directors, without notice other than an announcement at the meeting, until a quorum is present. If a 

 
Preferred Dividend Default shall terminate after the notice of a special meeting has been given but before such special meeting has been held, the Company shall, as soon as practicable after such
termination, mail or cause to be mailed notice of such termination to holders of the Series C Preferred Stock and the Parity Preferred that would have been entitled to vote at such special meeting. 

(e) If and when all accumulated dividends on such Series C Preferred Stock and all classes or series of Parity Preferred for the past
dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for payment, the right of the holders of Series C Preferred Stock and the Parity Preferred to elect such additional two directors shall
immediately cease (subject to revesting in the event of each and every Preferred Dividend Default), and the term of office of each Preferred Director so elected shall terminate and the entire Board of Directors shall be reduced accordingly. Any
Preferred Director may be removed at any time with or without cause by the vote of, and shall not be removed otherwise than by the vote of, the holders of record of a majority of the outstanding Series C Preferred Stock and the Parity Preferred
entitled to vote thereon when they have the voting rights set forth in Section 6(b) (voting as a single class). So long as a Preferred Dividend Default shall continue, any vacancy in the office of a Preferred Director may be filled by written
consent of the Preferred Director remaining in office, or if none remains in office, by a vote of the holders of record of a majority of the outstanding Series C Preferred Stock when they have the voting rights described above (voting as a single
class with all other classes or series of Parity Preferred). Each of the Preferred Directors shall be entitled to one vote on any matter. 
 (f) So long as any shares of Series C Preferred Stock remain outstanding, the affirmative vote or consent of the holders of two-thirds of the shares of Series C
Preferred Stock and each other class or series of preferred stock ranking on parity with the Series C Preferred Stock with respect to the payment of dividends and the distribution of assets upon liquidation, dissolution or winding up of the Company
upon which like voting rights have been conferred outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting as a single class) will be required to: (i) authorize, create or issue, or increase the authorized
or issued amount of, any class or series of capital stock ranking senior to the Series C Preferred Stock with respect to payment of dividends or the distribution of assets upon liquidation, dissolution or winding up of the affairs of the Company or
reclassify any authorized shares of capital stock of the Company into such capital stock, or create, authorize or issue any obligation or security convertible into or evidencing the right to purchase any such capital stock; or (ii) amend, alter
or repeal the provisions of the Charter or the terms of the Series C Preferred Stock, whether by merger, consolidation, transfer or conveyance of all or substantially all of its assets or otherwise (an “Event”), so as to materially
and adversely affect any right, preference, privilege or voting power of the Series C Preferred Stock; provided however, with respect to the occurrence of any of the Events set forth in (ii) above, so long as the Series C Preferred Stock
remains outstanding with the terms thereof materially unchanged, taking into account that, upon the occurrence of an Event, the Company may not be the surviving entity, the occurrence of such Event shall not be deemed to materially and adversely
affect such rights, preferences, privileges or voting power of Series C Preferred Stock, and in such case such holders shall not have any voting rights with respect to the occurrence of any of the Events set forth in (ii) above. In addition, if
the holders of the Series C Preferred Stock receive the greater of the full trading price of the Series C Preferred Stock on the date of an Event set forth in (ii) above or the $25.00 liquidation preference per share of the Series C Preferred
Stock pursuant to the occurrence of any of the Events set forth in (ii) above, then such holders shall not have any voting rights with respect to the Events set forth in (ii) above. Holders of shares of Series C Preferred Stock shall not
be entitled to vote with respect to: (a) any increase in the total number of authorized shares of Common Stock or Preferred Stock of the Company, or (b) any increase in the amount of the authorized Series C Preferred Stock or the creation
or issuance of any other class or series of capital stock, or (c) any increase in the number of authorized shares of any other class or series of capital stock, in each case referred to in clause (a) , (b) or (c) above ranking on
parity with or junior to the Series C Preferred Stock with respect to the payment of dividends and the distribution of assets upon liquidation, dissolution or winding up of the Company. Except as set forth herein, holders of the Series C Preferred
Stock shall not have any voting rights with respect to, and the consent of the holders of the Series C Preferred Stock shall not be required for, the taking of any corporate action, including an Event, regardless of the effect that such corporate
action or Event may have upon the powers, preferences, voting power or other rights or privileges of the Series C Preferred Stock. 
 (g) The foregoing voting provisions of this Section 6 shall not apply if, at or prior to the time when the act with respect to which such vote would otherwise be required shall be effected, all
outstanding shares of Series C Preferred Stock shall have been redeemed or called for redemption upon proper notice and sufficient funds, in cash, shall have been deposited in trust to effect such redemption. 

 (h) In any matter in which the Series C Preferred Stock may vote (as expressly provided
herein), each share of Series C Preferred Stock shall be entitled to one vote per $25.00 of liquidation preference.

other event, and such Purported Beneficial Transferee shall thereafter have no rights in such shares or (ii) if, for any reason, the transfer to the Trust described in clause (i) of this sentence is not automatically effective as provided
therein to prevent any Person from Beneficially or Constructively Owning Series C Preferred Stock in violation of Section 7(b)(i) of these Articles Supplementary, then the Transfer of that number of shares of Series C Preferred Stock that
otherwise would cause any Person to violate Section 7(b)(i) shall be void ab initio, and the Purported Beneficial Transferee shall have no rights in such shares. 

(iii) Subject to Section 7(l) and prior to the Restriction Termination Date, any Transfer of Series C Preferred Stock
that, if effective, would result in the capital stock of the Company being beneficially owned by fewer than 100 Persons (determined without reference to any rules of attribution) shall be void ab initio, and the intended transferee shall acquire no
rights in such Series C Preferred Stock. 
 (c) Transfers of Series C Preferred Stock in Trust. 

(i) Upon any purported Transfer or other event described in Section 7(b)(ii) of these Articles Supplementary, such
Series C Preferred Stock shall be deemed to have been transferred to the Trustee in his capacity as trustee of a Trust for the exclusive benefit of one or more Charitable Beneficiaries. Such transfer to the Trustee shall be deemed to be effective as
of the close of business on the Business Day prior to the purported Transfer or other event that results in a transfer to the Trust pursuant to Section 7(b)(ii). The Trustee shall be appointed by the Company and shall be a Person unaffiliated
with the Company, any Purported Beneficial Transferee or any Purported Record Transferee. Each Charitable Beneficiary shall be designated by the Company as provided in Section 7(c)(vi) of these Articles Supplementary. 

(ii) Series C Preferred Stock held by the Trustee shall be issued and outstanding Series C Preferred Stock of the Company.
The Purported Beneficial Transferee or Purported Record Transferee shall have no rights in the shares of the Series C Preferred Stock held by the Trustee. The Purported Beneficial Transferee or Purported Record Transferee shall not benefit
economically from ownership of any shares held in trust by the Trustee, shall have no rights to dividends and shall not possess any rights to vote or other rights attributable to the shares of Series C Preferred Stock held in the Trust. 

(iii) The Trustee shall have all voting rights and rights to dividends with respect to Series C Preferred Stock held in
the Trust, which rights shall be exercised for the exclusive benefit of the Charitable Beneficiary. Any dividend or distribution paid to or on behalf of the Purported Record Transferee or Purported Beneficial Transferee prior to the discovery by the
Company that shares of Series C Preferred Stock have been transferred to the Trustee shall be paid to the Trustee upon demand, and any dividend or distribution declared but unpaid shall be paid when due to the Trustee with respect to such Series C
Preferred Stock. Any dividends or distributions so paid over to the Trustee shall be held in trust for the Charitable Beneficiary. The Purported Record Transferee and Purported Beneficial Transferee shall have no voting rights with respect to the
Series C Preferred Stock held in the Trust and, subject to Maryland law, effective as of the date the Series C Preferred Stock has been transferred to the Trustee, the Trustee shall have the authority (at the Trustee’s sole discretion)
(i) to rescind as void any vote cast by a Purported Record Transferee with respect to such Series C Preferred Stock prior to the discovery by the Company that the Series C Preferred Stock has been transferred to the Trustee and (ii) to
recast such vote in accordance with the desires of the Trustee acting for the benefit of the Charitable Beneficiary; provided, however, that if the Company has already taken irreversible corporate action, then the Trustee shall not have the
authority 

 
to rescind and recast such vote. Notwithstanding any other provision of these Articles Supplementary to the contrary, until the Company has received notification that the Series C Preferred Stock
has been transferred into a Trust, the Company shall be entitled to rely on its share transfer and other stockholder records for purposes of preparing lists of stockholders entitled to vote at meetings, determining the validity and authority of
proxies and otherwise conducting votes of stockholders. 
 (iv) Within twenty (20) days of receiving notice
from the Company that shares of Series C Preferred Stock have been transferred to the Trust, the Trustee of the Trust shall sell the shares of Series C Preferred Stock held in the Trust to a Person, designated by the Trustee, whose ownership of the
shares of Series C Preferred Stock will not violate the ownership limitations set forth in Section 7(b)(i). Upon such sale, the interest of the Charitable Beneficiary in the shares of Series C Preferred Stock sold shall terminate and the
Trustee shall distribute the net proceeds of the sale to the Purported Record Transferee and to the Charitable Beneficiary as provided in this Section 7(c)(iv). The Purported Record Transferee shall receive the lesser of (i) the price paid
by the Purported Record Transferee for the shares of Series C Preferred Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of
Series C Preferred Stock at Market Price, the Market Price of such shares of Series C Preferred Stock on the day of the event which resulted in the transfer of such shares of Series C Preferred Stock to the Trust) and (ii) the price per share
received by the Trustee (net of any commissions and other expenses of sale) from the sale or other disposition of the shares of Series C Preferred Stock held in the Trust. The Trustee may reduce the amount payable to the Purported Record Transferee
by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 7(c)(iii). Any net sales proceeds in excess of the amount
payable to the Purported Record Transferee shall be immediately paid to the Charitable Beneficiary together with any dividends or other distributions thereon. If, prior to the discovery by the Company that shares of such Series C Preferred Stock
have been transferred to the Trustee, such shares of Series C Preferred Stock are sold by a Purported Record Transferee then (i) such shares of Series C Preferred Stock shall be deemed to have been sold on behalf of the Trust and (ii) to
the extent that the Purported Record Transferee received an amount for such shares of Series C Preferred Stock that exceeds the amount that such Purported Record Transferee was entitled to receive pursuant to this Section 7(c)(iv), such excess
shall be paid to the Trustee upon demand. 
 (v) Series C Preferred Stock transferred to the Trustee shall be
deemed to have been offered for sale to the Company, or its designee, at a price per share equal to the lesser of (i) the price paid by the Purported Record Transferee for the shares of Series C Preferred Stock in the transaction that resulted
in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Series C Preferred Stock at Market Price, the Market Price of such shares of Series C Preferred Stock on the day
of the event which resulted in the transfer of such shares of Series C Preferred Stock to the Trust) and (ii) the Market Price on the date the Company, or its designee, accepts such offer. The Company may reduce the amount payable to the
Purported Record Transferee by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 7(c)(iii). The Company shall
have the right to accept such offer until the Trustee has sold the shares of Series C Preferred Stock held in the Trust pursuant to Section 7(c)(iv). Upon such a sale to the Company, the interest of the Charitable Beneficiary in the shares of
Series C Preferred Stock sold shall terminate and the Trustee shall distribute the net proceeds of the sale to the Purported Record Transferee and any dividends or other distributions held by the Trustee with respect to such Series C Preferred Stock
shall thereupon be paid to the Charitable Beneficiary. 
 (vi) By written notice to the Trustee, the Company
shall designate one or more nonprofit organizations to be the Charitable Beneficiary of the interest in the Trust such that the Series C Preferred Stock held in the Trust would not violate the restrictions set forth in Section 7(b)(i) in the
hands of such Charitable Beneficiary. 
 (d) Remedies For Breach. If the Board of Directors or a committee thereof or
other designees if permitted by the MGCL shall at any time determine in good faith that a Transfer or other event has taken place in violation of Section 7(b) of these Articles Supplementary or that a Person intends to acquire, has attempted to
acquire or may acquire beneficial ownership (determined without reference to any rules of attribution), Beneficial 

 
Ownership or Constructive Ownership of any shares of Series C Preferred Stock of the Company in violation of Section 7(b) of these Articles Supplementary, the Board of Directors or the
Committee or other designees if permitted by the MGCL shall take such action as it deems advisable to refuse to give effect or to prevent such Transfer, including, but not limited to, causing the Company to redeem shares of Series C Preferred Stock,
refusing to give effect to such Transfer on the books of the Company or instituting proceedings to enjoin such Transfer; provided, however, that any Transfers (or, in the case of events other than a Transfer, ownership or Constructive
Ownership or Beneficial Ownership) in violation of Section 7(b)(i) of these Articles Supplementary, shall automatically result in the transfer to a Trust as described in Section 7(b)(ii) and any Transfer in violation of
Section 7(b)(iii) shall automatically be void ab initio irrespective of any action (or non-action) by the Board of Directors. 
 (e) Notice of Restricted Transfer. Any Person who acquires or attempts to acquire shares of Series C Preferred Stock in violation of Section 7(b) of these Articles Supplementary, or any Person
who is a Purported Beneficial Transferee such that an automatic transfer to a Trust results under Section 7(b)(ii) of these Articles Supplementary, shall immediately give written notice to the Company of such event and shall provide to the
Company such other information as the Company may request in order to determine the effect, if any of such Transfer or attempted Transfer on the Company’s status as a REIT. 

(f) Owners Required To Provide Information. Prior to the Restriction Termination Date each Person who is a beneficial owner or
Beneficial Owner or Constructive Owner of Series C Preferred Stock and each Person (including the stockholder of record) who is holding Series C Preferred Stock for a beneficial owner or Beneficial Owner or Constructive Owner shall provide to the
Company such information that the Company may request, in good faith, in order to determine the Company’s status as a REIT. 
 (g) Remedies Not Limited. Nothing contained in these Articles Supplementary (but subject to Section 7(l) of these Articles Supplementary) shall limit the authority of the Board of Directors to
take such other action as it deems necessary or advisable to protect the Company and the interests of its stockholders by preservation of the Company’s status as a REIT. 
 (h) Ambiguity. In the case of an ambiguity in the application of any of the provisions of this Section 7 of these Articles Supplementary, including any definition contained in
Section 7(a), the Board of Directors shall have the power to determine the application of the provisions of this Section 7 with respect to any situation based on the facts known to it (subject, however, to the provisions of
Section 7(l) of these Articles Supplementary). In the event Section 7 requires an action by the Board of Directors and these Articles Supplementary fail to provide specific guidance with respect to such action, the Board of Directors shall
have the power to determine the action to be taken so long as such action is not contrary to the provisions of Section 7. Absent a decision to the contrary by the Board of Directors (which the Board of Directors may make in its sole and
absolute discretion), if a Person would have (but for the remedies set forth in Section 7(b)) acquired Beneficial or Constructive Ownership of Series C Preferred Stock in violation of Section 7(b)(i), such remedies (as applicable) shall
apply first to the shares of Series C Preferred Stock which, but for such remedies, would have been actually owned by such Person, and second to shares of Series C Preferred Stock, which, but for such remedies, would have been Beneficially Owned or
Constructively Owned (but not actually owned) by such Person, pro rata among the Persons who actually own such shares of Series C Preferred Stock based upon the relative number of the shares of Series C Preferred Stock held by each such Person.

 (i) Exceptions. 
 (i) Subject to Section 7(b)(i)(D), the Board of Directors, in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Beneficially Owning shares of
Series C Preferred Stock in violation of Section 7(b)(i)(A) or Section 7(b)(i)(C) if the Board of Directors determines that such exemption will not cause any Individual’s Beneficial Ownership of shares of Capital Stock to violate the
Aggregate Stock Ownership Limit and that such exemption will not cause the Company to fail to qualify as a REIT under the Code. 
 (ii) Subject to Section 7(b)(i)(D), the Board of Directors, in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Constructively Owning shares
of Series C Preferred Stock in violation of Section 7(b)(i)(B) or Section 7(b)(i)(C) if the Board of Directors determines that such ownership would not cause the Company to fail to qualify as a REIT under the Code. 

 (iii) Subject to Section 7(b)(i)(D) and the remainder of this
Section 7(i)(iii), the Board of Directors may from time to time increase or decrease the Ownership Limit; provided, however, that the decreased Ownership Limit will not be effective for any Person whose percentage ownership of Series C
Preferred Stock is in excess of such decreased Ownership Limit until such time as such Person’s percentage of Series C Preferred Stock equals or falls below the decreased Ownership Limit, but any further acquisition of Series C Preferred Stock
in excess of such percentage ownership of Series C Preferred Stock will be in violation of the Ownership Limit, and, provided further, that the new Ownership Limit would not allow five or fewer Persons to Beneficially Own more than 49% in value of
the outstanding capital stock of the Company. 
 (iv) In granting a person an exemption under
Section 7(i)(i) or (ii) above, the Board of Directors may require such Person to make certain representations or undertakings or to agree that any violation or attempted violation of such representations or undertakings (or other action
which is contrary to the restrictions contained in Section 7(b) of these Articles Supplementary) will result in such Series C Preferred Stock being transferred to a Trust in accordance with Section 7(b)(ii) of these Articles Supplementary.
In granting any exception pursuant to Section 7(i)(i) or (ii) of these Articles Supplementary, the Board of Directors may require a ruling from the IRS, or an opinion of counsel, in either case in form and substance satisfactory to the
Board of Directors in its sole discretion, as it may deem necessary or advisable in order to determine or ensure the Company’s status as a REIT. 
 (j) Legends. Each certificate for Series C Preferred Stock shall bear substantially the following legends in addition to any legends required to comply with federal and state securities laws:

MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SERIES C PREFERRED STOCK THAT, TAKING INTO ACCOUNT ANY OTHER CAPITAL STOCK OF THE COMPANY BENEFICIALLY OR CONSTRUCTIVELY OWNED BY SUCH PERSON, WOULD RESULT IN THE COMPANY BEING “CLOSELY HELD” UNDER

(k) Severability. If any provision of this Section 7 or any application of any such provision is determined to be invalid by
any federal or state court having jurisdiction over the issues, the validity of the remaining provisions shall not be affected and other applications of such provision shall be affected only to the extent necessary to comply with the determination
of such court. 
 (l) NYSE. Nothing in this Section 7 shall preclude the settlement of any transaction entered into
through the facilities of the NYSE. The shares of Series C Preferred Stock that are the subject of such transaction shall continue to be subject to the provisions of this Section 7 after such settlement. 

(m) Applicability of Section 7. The provisions set forth in this Section 7 shall apply to the Series C Preferred Stock

 (ii) any
“person” or “group” (as such terms are used for purposes of Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended, whether or not applicable), other than the Company, the Company’s operating partnership
subsidiary, Digital Realty Trust, L.P. (the “Operating Partnership”) or any of the Company’s or the Operating Partnership’s majority-owned subsidiaries or any employee benefit plan of the Company, the Operating Partnership
or such subsidiary, is or becomes the “beneficial owner,” directly or indirectly, of more than 50% of the total voting power in the aggregate of all classes of the Company’s capital stock of then outstanding entitled to vote generally

(iii) during any period of 12 consecutive months after the date of original issuance of the Series C Preferred Stock,
persons who at the beginning of such 12 month period constituted the Company’s board of directors, together with any new persons whose election was approved by a vote of a majority of the persons then still comprising the Company’s board

of these Articles Supplementary. 

 “Market Price” means, with respect to any Fundamental Change Conversion
Date, the average of the Closing Sale Prices of the Common Stock for the ten consecutive Trading Days ending on the third Trading Day prior to the Fundamental Change Conversion Date, appropriately adjusted to take into account the occurrence, during
the period commencing on the first Trading Day of such ten Trading Day period and ending on the Fundamental Change Conversion Date of any event requiring an adjustment of the Conversion Rate as described under Section 8(h); provided that in no
event shall the market price be less than $0.01, subject to adjustment for share splits and combinations, reclassifications and similar events. 
 “NYSE” means the New York Stock Exchange, Inc. 

“SEC” means the U.S. Securities and Exchange Commission.

 (b) Conversion at
Holder’s Option. 
 (i) Holders of shares of Series C Preferred Stock, at their option, may, at any time
and from time to time, convert some or all of their outstanding shares of Series C Preferred Stock into Common Stock at the then applicable Conversion Rate. 
 (ii) The Company shall not issue fractional shares of Common Stock upon the conversion of shares of Series C Preferred Stock. Instead, the Company shall pay the cash value of such fractional shares based
upon the Closing Sale Price of its Common Stock on the Trading Day (as defined in this Section 8) immediately prior to (A) the date on which the certificate or certificates representing the shares of Series C Preferred Stock to be
converted are surrendered, accompanied by a written notice of conversion and any required transfer taxes (the “Conversion Date”), or (B) the effective date for the Company’s Conversion Option, as the case may be.

 (iii) A holder of shares of Series C Preferred Stock is not entitled to any rights of a common stockholder of
the Company until such holder of shares of Series C Preferred Stock has converted its shares of Series C Preferred Stock or unless the Company has exercised its Conversion Option, and only to the extent the shares of Series C Preferred Stock are
deemed to have been converted into shares of Common Stock under these Articles Supplementary. 
 (iv)
Notwithstanding anything herein to the contrary, holders of shares of Series C Preferred Stock may not convert their outstanding shares of Series C Preferred Stock into Common Stock if such conversion would cause the holder to violate the Aggregate
Stock Ownership Limit or Common Stock Ownership Limit or otherwise result in the Company failing to qualify as a REIT. 
 (v) Conversion Procedures. Holders of shares of Series C Preferred Stock may convert some or all of their shares by surrendering to the Company at its principal office or at the office of its
transfer agent, as may be designated by the Board of Directors, the certificate or certificates for the shares of Series C Preferred Stock to be converted, accompanied by a written notice stating that the holder of shares of Series C Preferred Stock
elects to convert all or a specified whole number of those shares in accordance with the provisions described in this Section 8 and specifying the name or names in which the holder of shares of Series C Preferred Stock wishes the certificate or
certificates for the shares of Common Stock to be issued. If the notice specifies a name or names other than the name of the holder of shares of Series C Preferred Stock, the notice shall be accompanied by payment of all transfer taxes payable upon
the issuance of shares of Common Stock in that name or names. Other than such transfer taxes, the Company shall pay any documentary, stamp or similar issue or transfer taxes that may be payable in respect of any issuance or delivery of shares of
Common Stock upon conversion of shares of Series C Preferred Stock. The date on which the Company has received all of the surrendered certificate or certificates, the notice relating to the conversion and payment of all required transfer taxes, if
any, or the demonstration to the Company’s satisfaction that those taxes have been paid, shall be deemed the Conversion Date with respect 

 
to a share of Series C Preferred Stock. As promptly as practicable after the Conversion Date with respect to any shares of Series C Preferred Stock, the Company shall deliver or cause to be
delivered (A) certificates representing the number of validly issued, fully paid and non-assessable shares of Common Stock to which the holders of shares of such Series C Preferred Stock, or the
transferee of the holder of such shares of Series C Preferred Stock, shall be entitled and (B) if less than the full number of shares of Series C Preferred Stock evidenced by the surrendered certificate or certificates is being converted, a new
certificate or certificates, of like tenor, for the number of shares evidenced by the surrendered certificate or certificates, less the number of shares being converted. This conversion shall be deemed to have been made at the close of business on
the Conversion Date so that the rights of the holder of shares of Series C Preferred Stock as to the shares being converted shall cease except for the right to receive the conversion value, and, if applicable, the person entitled to receive shares
of Common Stock shall be treated for all purposes as having become the record holder of those shares of Common Stock at that time on that date. 
 (vi) In lieu of the foregoing procedures, if the Series C Preferred Stock is held in global certificate form, the holder of shares of Series C Preferred Stock must comply with the procedures of DTC to
convert its beneficial interest in respect of the Series C Preferred Stock evidenced by a global stock certificate of the Series C Preferred Stock. 
 (vii) If any shares of Series C Preferred Stock are to be converted pursuant to the Company’s Conversion Option, the right of a holder of such to voluntarily convert those shares of Series C
Preferred Stock shall terminate if the Company has not received the conversion notice of such holder of such shares of Series C Preferred Stock by 5:00 p.m., New York City time, on the business day immediately preceding the date fixed for conversion
pursuant to the Company’s Conversion Option. 
 (viii) If more than one share of Series C Preferred Stock is
surrendered for conversion by the same holder at the same time, the number of whole shares of Common Stock issuable upon conversion of those shares of Series C Preferred Stock shall be computed on the basis of the total number of shares of Series C
Preferred Stock so surrendered. 
 (c) Company Conversion Option. 

(i) On or after April 10, 2012, the Company may exercise its Conversion Option, as described below, but only if
(A) the Closing Sale Price of the Common Stock equals or exceeds 130% of the then-applicable Conversion Price per share of the Series C Preferred Stock 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 Company’s issuance of a press release announcing the exercise of its Conversion Option as described below in paragraph (iii); and (B) on or prior to the
Effective Date of the exercise of its Conversion Option, the Company has either declared and paid, or declared and set apart for payment, any unpaid dividends that are in arrears on the Series C Preferred Stock. 

(ii) If the Company converts less than all of the outstanding shares of Series C Preferred Stock, the Company’s
transfer agent shall select the shares by lot, on a pro rata basis or in accordance with any other method the transfer agent considers fair and appropriate. The Company may convert the Series C Preferred Stock only in a whole number of shares of
Series C Preferred Stock. If a portion of a holder’s Series C Preferred Stock is selected for partial conversion by the Company and the holder converts a portion of such Series C Preferred Stock, the number of shares of Series C Preferred Stock
subject to conversion by the Company shall be reduced by the number of shares that the holder converted. 
 (iii)
To exercise its Conversion Option described above, the Company shall issue a press release for publication on 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 conditions described in Section 8(c)(i) are met, announcing such conversion. The Company shall also give notice by mail or by publication (with subsequent prompt notice by mail) to holders of shares of Series C Preferred Stock (not
more than four Trading Days after the date of the press release) and, if required by the rules and regulations of the SEC, the Company shall file a Current Report on Form 8-K (or make such

 
other filing on an appropriate form as may be permitted by the rules and regulations of the SEC), of the exercise of the Company’s Conversion Option announcing its intention to convert
Series C Preferred Stock. The Effective Date for the Company’s Conversion Option shall be the date that is five Trading Days after the date on which the Company issues such press release. 

(iv) In addition to any information required by applicable law or regulation, the press release and notice of the exercise
of the Company’s Conversion Option referred to in paragraph (iii) above shall state, as appropriate: (A) the Effective Date for its Conversion Option; (B) the number of shares of Common Stock to be issued upon conversion of each
share of Series C Preferred Stock; (C) the number of shares of Series C Preferred Stock to be converted; and (D) that dividends on the shares of Series C Preferred Stock to be converted shall cease to accrue on the Effective Date for the
Company’s Conversion Option (and no dividends on such converted shares shall be payable except as provided in these Articles Supplementary). 
 (d) Reservation of Shares. The Company shall at all times reserve and keep available, free from preemptive rights out of the Company’s authorized but unissued shares of capital stock, for
issuance upon the conversion of shares of Series C Preferred Stock, a number of the Company’s authorized but unissued shares of Common Stock that shall from time to time be sufficient to permit the conversion of all outstanding shares of Series
C Preferred Stock. 
 (e) Compliance with Laws; Validity, etc., of Common Stock. Before the delivery of any securities
upon conversion of shares of Series C Preferred Stock, the Company shall comply with all applicable federal and state laws and regulations. All shares of Common Stock delivered upon conversion of shares of Series C Preferred Stock shall, upon
delivery, be duly and validly issued, fully paid and non-assessable, free of all liens and charges and not subject to any preemptive rights. 

(f) Payment of Dividends Upon Conversion; Optional Conversion. 

(i) If a holder of shares of Series C Preferred Stock exercises its conversion rights, upon delivery of the shares of
Series C Preferred Stock for conversion, those shares of Series C Preferred Stock shall cease to cumulate dividends as of the end of the Conversion Date, and the holder of shares of Series C Preferred Stock shall not receive any cash payment in an
amount equal to accrued and unpaid dividends on the shares of Series C Preferred Stock, except in those limited circumstances discussed below in this Section 8(f). Except as provided below in this Section 8(f), the Company shall make no
payment for accrued and unpaid dividends, whether or not in arrears, on shares of Series C Preferred Stock converted at the election of holders of such shares. 
 (ii) If the Company receives a conversion notice before the close of business on a Dividend Record Date, the holder of shares of Series C Preferred Stock shall not be entitled to receive any portion of
the dividend payable on such shares of converted stock on the corresponding Dividend Payment Date. 
 (iii) If
the Company receives a conversion notice after the Dividend Record Date but prior to the corresponding Dividend Payment Date, the holder of shares of Series C Preferred Stock on the Dividend Record Date will receive on that Dividend Payment Date
accrued dividends on those shares of Series C Preferred Stock, notwithstanding the conversion of those shares of Series C Preferred Stock prior to that Dividend Payment Date, because that holder of shares of Series C Preferred Stock will have been
the holder of record of shares of Series C Preferred Stock on the corresponding Dividend Record Date. At the time that such holder of shares of Series C Preferred Stock surrenders shares of Series C Preferred Stock for conversion, however, it shall
pay to the Company an amount equal to the dividend that has accrued and that will be paid on the related Dividend Payment Date; provided that no such payment need be made if the Company has specified a Fundamental Change Repurchase Date relating to
a Fundamental Change that is after a Dividend Record Date and on or prior to the Dividend Payment Date to which that Dividend Record Date relates. 
 (iv) If the holder of shares of Series C Preferred Stock is a holder of shares of Series C Preferred Stock on a Dividend Record Date and converts such shares of Series C Preferred Stock into shares of
Common Stock on or after the corresponding Dividend Payment Date such holder of shares of Series C 

 
Preferred Stock shall be entitled to receive the dividend payable on such shares of Series C Preferred Stock on such corresponding Dividend Payment Date, and the holder of shares of Series C
Preferred Stock shall not need to include payment of the amount of such dividend upon surrender for conversion of shares of Series C Preferred Stock. 
 (g) Payment of Dividends Upon Conversion; Company Conversion Option. 
 (i) If the Company converts shares of Series C Preferred Stock pursuant to its Conversion Option, on or prior to the Effective Date of the Conversion Option, the Company must first declare and pay, or
declare and set apart for payment, any unpaid dividends that are in arrears on Series C Preferred Stock. 
 (ii)
If the Company exercises its Conversion Option and the Effective Date 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 shares of Series C Preferred Stock
shall not be entitled to receive any portion of the dividend payable for such period on such converted shares on the corresponding Dividend Payment Date. Accordingly, if the Company converts shares of Series C Preferred Stock and the effective date
is after the close of business on a Dividend Payment Date and prior to the close of business on the next Dividend Record Date, holders of shares of Series C Preferred Stock shall forego the right to receive any dividends accruing from such Dividend
Payment Date to the Effective Date. 
 (iii) If the Company exercises its Conversion Option and the Effective
Date 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 payable for such period with respect to the shares of Series C Preferred Stock called
for a conversion on such date, shall be payable on such Dividend Payment Date to the holder of such shares of Series C Preferred Stock on such Dividend Record Date. 
 (h) Conversion Rate Adjustments. The Company shall adjust the conversion rate from time to time as follows: 
 (i) If the Company issues shares of Common Stock as a dividend or distribution on shares of Common Stock to all holders of Common Stock, or if the Company effects a share split or share combination, the
conversion rate shall be adjusted based on the following formula: 
 CR1 = CR0 x OS1/OS0 
 where

 CR0 = the conversion rate in effect immediately prior to the ex-dividend date for such
dividend or distribution, or the effective date of such share split or share combination; 
 CR1 = the new conversion rate in effect immediately on and after the ex-dividend date for such dividend or distribution, or the effective date of such share split or share combination; 
 OS1 = the number
of shares of Common Stock outstanding immediately after such dividend or distribution, or the effective date of such share split or share combination; and 
 OS0 = the number
of shares of Common Stock outstanding immediately prior to such dividend or distribution, or the effective date of such share split or share combination. 
 Any adjustment made pursuant to this paragraph (i) shall become effective at the open of business on (x) the ex-dividend date for such dividend or other
distribution or (y) the date on which such split or combination becomes effective, as applicable. If any dividend or distribution described in this paragraph (i) is declared but not so paid or made, the new conversion rate shall be
readjusted to the conversion rate that would then be in effect if such dividend or distribution had not been declared. 
 (ii) If the Company distributes to all holders of Common Stock any rights, warrants or options entitling them, for a period expiring not more than 45 days after the date of issuance of such rights,

 
warrants or options, to subscribe for or purchase shares of Common Stock at a price per share that is less than the Closing Sale Price per share of Common Stock on the business day immediately
preceding the time of announcement of such distribution, the Company shall adjust the conversion rate based on the following formula: 
 CR1 = CR0 x (OS0+X)/(OS0+Y) 
 where

 CR0 = the conversion rate in effect immediately prior to the ex-dividend date for such
distribution; 
 CR1 = the new conversion rate in effect immediately on and after the ex-dividend date
for such distribution; 
 OS0 = the number of shares of Common Stock outstanding immediately prior to the
ex-dividend date for such distribution; 
 X = the aggregate number of shares of Common
Stock issuable pursuant to such rights, warrants or options; and 
 Y = the number of shares of Common Stock equal to the
quotient of (A) the aggregate price payable to exercise such rights, warrants or options and (B) the average of the Closing Sale Price per share of Common Stock for the 10 consecutive Trading Days ending on the business day immediately
preceding the date of announcement for the issuance of such rights, warrants or options. 
 For purposes of this paragraph (ii),
in determining whether any rights, warrants or options entitle the holders of shares of Common Stock to subscribe for or purchase shares of Common Stock at less than the applicable Closing Sale Price per share of Common Stock, and in determining the
aggregate exercise or conversion price payable for such shares of Common Stock, there shall be taken into account any consideration the Company receives for such rights, warrants or options and any amount payable on exercise or conversion thereof,
with the value of such consideration, if other than cash, to be determined by the Company’s board of directors. If any right, warrant or option described in this paragraph (ii) is not exercised or converted prior to the expiration of the
exercisability or convertibility thereof, the Company shall adjust the new conversion rate to the conversion rate that would then be in effect if such right, warrant or option had not been so issued. 

(iii) If the Company distributes shares of its capital stock, evidence of indebtedness or other assets or property to all
holders of Common Stock, excluding (A) dividends, distributions, rights, warrants or options referred to in paragraph (i) or (ii) above; (B) dividends or distributions paid exclusively in cash; and (C) spin-offs, as
described below in this paragraph (iii) then the Company shall adjust the conversion rate based on the following formula: 
 CR1 = CR0 x SP0/(SP0 – FMV) 

where 

CR0 = the conversion rate in effect immediately prior to the ex-dividend date for such
distribution; 
 CR1 = the new conversion rate in effect immediately on and after the ex-dividend date
for such distribution; 
 SP0 = the average of the Closing Sale Price per share of Common Stock for the 10 consecutive Trading Days ending on the
business day immediately preceding the ex-dividend date for such distribution; and 
 FMV
= the fair market value (as determined in good faith by the Company’s board of directors) of the shares of capital stock, evidences of indebtedness, assets or property distributed with respect to each outstanding share of Common Stock on the
earlier of the record date or the ex-dividend date for such distribution; 

 provided that if “FMV” with respect to any distribution of shares of capital
stock, evidences of indebtedness or other assets or property of the Company is equal to or greater than
“SP0” with respect to such distribution, then in
lieu of the foregoing adjustment, adequate provision shall be made so that each holder of Series C Preferred Stock shall have the right to receive on the date such shares of capital stock, evidences of indebtedness or other assets or property of the
Company are distributed to holders of Common Stock, for each share of Series C Preferred Stock, the amount of shares of capital stock, evidences of indebtedness or other assets or property of the Company such holder of Series C Preferred Stock would
have received had such holder of Series C Preferred Stock owned a number of shares of Common Stock equal to a fraction the numerator of which is the product of the conversion rate in effect on the ex-dividend
date for such distribution, and the aggregate liquidation preference of Series C Preferred Stock held by such holder and the denominator of which is twenty-five ($25.00). 
 An adjustment to the conversion rate made pursuant to the immediately preceding paragraph shall become effective on the ex-dividend date for such distribution.

 If the Company distributes to all holders of Common Stock capital stock of any class or series, or similar equity interest,
of or relating to one of the Company’s subsidiaries or other business unit (a “spin-off”) the conversion rate in effect immediately before the 10th Trading Day from and including the effective date of the spin-off shall be adjusted based on the following formula: 
 CR1 = CR0 x (FMV0+MP0 )/ MP0 
 where

 CR0 = the conversion rate in effect immediately prior to the 10th Trading Day immediately following, and including, the
effective date of the spin-off; 
 CR1 = the new conversion rate in effect immediately on and after the 10th Trading Day immediately following, and including,
the effective date of the spin-off; 
 FMV0 = the average of the Closing Sale Prices per share of the capital stock or similar equity interest distributed to holders
of Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading Days after the effective date of the spin-off; and 
 MP0 = the
average of the Closing Sale Prices per share of Common Stock over the first 10 consecutive Trading Days after the effective date of the spin-off. 
 An adjustment to the conversion rate made pursuant to the immediately preceding paragraph shall occur on the 10th Trading Day from and including the effective date of the spin-off; provided that in
respect of any conversion within the 10 Trading Days following the effective date of any spin-off, references within this paragraph (iii) to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed
between the effective date of such spin-off and the Conversion Date in determining the applicable conversion rate. 
 If any such dividend or distribution described in this paragraph (iii) is declared but not paid or made, the new conversion rate shall be re-adjusted to be the
conversion rate that would then be in effect if such dividend or distribution had not been declared. 
 (iv) If
the Company makes any cash dividend or distribution to all holders of outstanding shares of Common Stock (excluding any dividend or distribution in connection with the Company’s liquidation, dissolution or winding up) during any of its
quarterly fiscal periods in an aggregate amount that, together with other cash dividends or distributions made during such quarterly fiscal period, exceeds the product of $0.28625 (subject to adjustment) (the “reference dividend”),
multiplied by the number of shares of Common Stock outstanding on the record date for such distribution, the conversion rate shall be adjusted based on the following formula: 

CR1 = CR0 x SP0/(SP0 – C) 

 where 
 CR0 = the
conversion rate in effect immediately prior to the ex-dividend date for such distribution; 
 CR1 = the new
conversion rate in effect immediately after the ex-dividend date for such distribution; 
 SP0 = the
average of the Closing Sale Price per share of Common Stock for the 10 consecutive Trading Days ending on the business day immediately preceding the earlier of the record date or the day prior to the
ex-dividend date for such distribution; and 
 C = the amount in cash per share that the
Company distributes to holders of Common Stock that exceeds the reference dividend; 
 provided that if “C” with
respect to any such cash dividend or distribution is equal to or greater than “SP0” with respect to any such cash dividend or distribution, then in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of Series C Preferred Stock shall have the
right to receive on the date such cash is distributed to holders of Common Stock, for each share of Series C Preferred Stock, the amount of cash such holder of Series C Preferred Stock would have received had such holder of Series C Preferred Stock
owned a number of shares of Common Stock equal to a fraction the numerator of which is the product of the conversion rate in effect on the ex-dividend date for such dividend or distribution, and the aggregate
principal amount of Series C Preferred Stock held by such holder and the denominator of which is twenty-five ($25.00). 
 An
adjustment to the conversion rate made pursuant to this paragraph (iv) shall become effective on the ex-dividend date for such dividend or distribution. If any dividend or distribution described in this
paragraph (iv) is declared but not so paid or made, the new conversion rate shall be re-adjusted to the conversion rate that would then be in effect if such dividend or distribution had not been declared.

 The reference dividend amount is subject to adjustment in a manner inversely proportional to adjustments to the conversion
rate; provided that no adjustment shall be made to the reference dividend amount for any adjustment made to the conversion rate under this paragraph (iv). 
 Notwithstanding the foregoing, if an adjustment is required to be made under this paragraph (iv) as a result of a distribution that is not a quarterly dividend, the reference dividend amount shall be
deemed to be zero. 
 (v) If the Company or any of its subsidiaries makes a payment in respect of a tender offer
or exchange offer for shares of Common Stock to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Closing Sale Price per share of Common Stock on the Trading Day next
succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer, the conversion rate shall be adjusted based on the following formula: 

CR1 = CR0 × (AC + (SP1 × OS1))/(SP1 × OS0) 
 where

 CR0 = the conversion rate in effect on the day immediately following the date such tender or exchange offer expires;

 CR1 = the conversion rate in effect on the second day immediately following the date such tender or exchange offer expires;

 AC = the aggregate value of all cash and any other consideration (as determined by the Company’s board of directors) paid
or payable for shares of Common Stock purchased in such tender or exchange offer; 
 OS0 = the number of shares of Common Stock outstanding immediately prior to
the date such tender or exchange offer expires; 

 OS1 = the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after
giving effect to the purchase or exchange of shares pursuant to such tender or exchange offer); and 

SP1 = the Closing Sale Price per share of Common Stock for the Trading Day immediately following the date such tender or
exchange offer expires. 
 If 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 to the conversion rate made pursuant to this paragraph
(v) shall become effective on the second day immediately following the date such tender offer or exchange offer expires. If the Company or one of its subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender or
exchange offer but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the Company shall re-adjust the new conversion rate to be the conversion rate
that would be in effect if such tender or exchange offer had not been made. 
 (vi) If the Company has in effect
a rights plan while any shares of Series C Preferred Stock remain outstanding, holders of shares of Series C Preferred Stock shall receive, upon a conversion of such shares in respect of which the Company has elected to deliver shares of Common
Stock, in addition to such shares of Common Stock, rights under the Company’s stockholder rights agreement unless, prior to conversion, the rights have expired, terminated or been redeemed or unless the rights have separated from Common Stock.
If the rights provided for in any rights plan that the Company’s board of directors may adopt have separated from the Common Stock in accordance with the provisions of the applicable stockholder rights agreement so that holders of shares of
Series C Preferred Stock would not be entitled to receive any rights in respect of Common Stock that the Company elects to deliver upon conversion of shares of Series C Preferred Stock, the Company shall adjust the conversion rate at the time of
separation as if the Company had distributed to all holders of the Company’s capital stock, evidences of indebtedness or other assets or property pursuant to paragraph (iii) above, subject to readjustment upon the subsequent expiration,
termination or redemption of the rights. 
 (vii) Notwithstanding the foregoing, in the event of an adjustment to
the conversion rate pursuant to paragraphs (iv) and (v) above, in no event shall the conversion rate exceed 0.6197 shares of Common Stock per $25.00 liquidation preference, subject to adjustment pursuant to paragraphs (i), (ii) and
(iii) above. In no event shall the Conversion Price be reduced below $0.01, subject to adjustment for share splits and combinations and similar events. 
 (viii) The Company shall not make any adjustment to the conversion rate if holders of shares of Series C Preferred Stock are permitted to participate, on an
as-converted basis, in the transactions described in paragraphs (i) through (vi) above. 
 (ix) The conversion rate shall not be adjusted except as specifically set forth in this Section 8 to these Articles Supplementary. Without limiting the foregoing, the conversion rate shall not be
adjusted for (A) the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities or those of the Operating Partnership and the
investment of additional optional amounts in shares of Common Stock under any plan; (B) the issuance of any shares of Common Stock or options or rights to purchase such shares pursuant to any of the Company’s present or future employee,
director, trustee or consultant benefit plan, employee agreement or arrangement or program or those of the Operating Partnership; (C) the issuance of any shares of Common Stock pursuant to any option, warrant, right, or exercisable,
exchangeable or convertible security outstanding as of the date shares of Series C Preferred Stock were first issued; (D) a change in the par value of Common Stock; (E) accumulated and unpaid dividends or distributions; and (F) the
issuance of limited partnership units by the Operating Partnership and the issuance of shares of Common Stock or the payment of cash upon redemption thereof. 
 (x) No adjustment in the conversion rate shall be required unless the adjustment would require an increase or decrease of at least 1% of the conversion rate. If the adjustment is not made because the
adjustment does not change the conversion rate by at least 1%, then the adjustment that is not made 

 
shall be carried forward and taken into account in any future adjustment. All required calculations shall be made to the nearest cent or 1/1000th of a share, as the case may be. Notwithstanding
the foregoing, if the shares of Series C Preferred Stock are called for redemption, all adjustments not previously made shall be made on the applicable redemption date. 

(xi) Except as described in this Section 8 of these Articles Supplementary, the Company shall not adjust the
conversion rate for any issuance of shares of Common Stock or any securities convertible into or exchangeable or exercisable for shares of Common Stock or rights to purchase shares of Common Stock or such convertible, exchangeable or exercisable
securities. 
 (i) Effect of Business Combinations. In the case of the following events (each a “business
combination”): 
 (i) any recapitalization, reclassification or change of Common Stock (other than
changes resulting from a subdivision or combination); 
 (ii) a consolidation, merger or combination involving
the Company; 
 (iii) a sale, conveyance or lease to another corporation of all or substantially all of the
Company’s property and assets (other than to one or more of the Company’s subsidiaries); or 
 (iv) a
statutory share exchange, 
 in each case, as a result of which holders of Common Stock 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 Stock, a holder of shares of Series C Preferred Stock shall be entitled thereafter to convert such shares of Series C Preferred Stock into the
kind and amount of stock, other securities or other property or assets (including cash or any combination thereof) which the holder of shares of Series C Preferred Stock would have owned or been entitled to receive upon such business combination as
if such holder of shares of Series C Preferred Stock held a number of shares of Common Stock equal to the conversion rate in effect on the effective date for such business combination, multiplied by the number of shares of Series C Preferred Stock
held by such holder of shares of Series C Preferred Stock. If such business combination also constitutes a Fundamental Change, a holder of shares of Series C Preferred Stock converting such shares shall not receive a make-whole premium pursuant to
Section 8(k) hereof if such holder does not convert its shares of Series C Preferred Stock “in connection with” (as described in Section 8(k)(i)) the relevant Fundamental Change. In the event that holders of Common Stock have the
opportunity to elect the form of consideration to be received in such business combination, the Company shall make adequate provision whereby the holders of shares of Series C Preferred Stock shall have a reasonable opportunity to determine the form
of consideration into which all of the shares of Series C Preferred Stock, 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 shares of Series C Preferred Stock who participate in such determination, shall be subject to any limitations to which all holders of Common Stock 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 (1) the deadline for elections to be made by holders of Common Stock and (2) two
business days prior to the anticipated effective date of the business combination. 
 The Company 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 shares of Series C Preferred Stock (and the weighted average of elections), by posting such notice with DTC and providing a copy
of such notice to the Company’s transfer agent. If the effective date of a business combination is delayed beyond the initially anticipated effective date, the holders of shares of Series C Preferred Stock shall be given the opportunity to make
subsequent similar determinations in regard to such delayed effective date. The Company may not become a party to any such transaction unless its terms are consistent with the preceding. None of the foregoing provisions shall affect the right of a
holder of shares of Series C Preferred Stock to convert such holder’s shares of Series C Preferred Stock into shares of Common Stock prior to the effective date of such business combination. 

 (j) Optional Increase to Conversion Rate. To the extent permitted by law, the Company
may, from time to time, increase the conversion rate for a period of at least 20 days if the Company’s board of directors determines that such an increase would be in the Company’s best interests. Any such determination by the
Company’s board of directors shall be conclusive. In addition, the Company may increase the conversion rate if the Company’s board of directors deems it advisable to avoid or diminish any income tax to holders of Common Stock resulting
from any distribution of Common Stock or similar event. The Company shall give holders of shares of Series C Preferred Stock at least 15 business days’ notice of any increase in the conversion rate. 

(k) Adjustment to Conversion Rate upon Certain Fundamental Changes. The Company shall adjust the conversion rate from time to time
as follows: 
 (i) If, on or prior to April 10, 2014, a Fundamental Change takes place and a holder converts
the Series C Preferred Stock in connection with such Fundamental Change, the Company shall increase, as described below, the conversion rate applicable to shares that are surrendered for conversion. A conversion of the Series C Preferred Stock shall
be deemed for these purposes to be “in connection with” a Fundamental Change if the Conversion Date occurs from and including the effective date of such Fundamental Change to, and including, the Fundamental Change Conversion Date (as
defined in Section 8(l)(vii)) for that Fundamental Change. 
 (ii) The Company shall also give notice by
mail or by publication (with subsequent prompt notice by mail) to holders of Series C Preferred Stock of the anticipated effective date of any proposed Fundamental Change which shall occur on or prior to April 10, 2014. The Company shall make
this mailing or publication at least 15 days before the anticipated effective date of the Fundamental Change. In addition, no later than the third business day after the completion of such Fundamental Change, the Company shall make an additional
notice announcing such completion. 
 (iii) If a holder elects to convert in connection with a Fundamental Change
on or prior to April 10, 2014, the Company shall increase the Conversion Rate by reference to the table below, based on the date when the Fundamental Change becomes effective (the “effective date”), and the applicable price. If
the Fundamental Change is a transaction or series of related transactions and the consideration (excluding cash payments for fractional shares or pursuant to statutory appraisal rights) for Common Stock in the Fundamental Change consists solely of
cash, then the applicable price shall be the cash amount paid per share of Common Stock in the transaction. If the transaction is an asset sale and the consideration paid for the Company’s property and assets (or for the property and assets of
the Company and its subsidiaries on a consolidated basis) consists solely of cash, then the applicable price shall be the cash amount paid for the Company’s property and assets, expressed as an amount per share of Common Stock outstanding on
the effective date of the asset sale. In all other cases, the applicable price shall be the average of the Closing Sale Price per share of Common Stock for the ten consecutive Trading Days immediately preceding the effective date. The Company’s
board of directors shall make appropriate adjustments, in its good faith determination, to account for any adjustment to the conversion rate that becomes effective, or any event requiring an adjustment to the conversion rate where the ex-dividend date of the event occurs, at any time during those ten consecutive Trading Days. 
 (iv) The following table sets forth the number of additional shares of Common Stock per $25.00 liquidation preference of Series C Preferred Stock that shall be added to the Conversion Rate applicable to
Series C Preferred Stock that are converted in connection with a Fundamental Change (the “make-whole premium”). If an event occurs that requires an adjustment to the Conversion Rate, the Company shall, on the date the Company must
adjust the Conversion Rate, adjust each applicable price set forth in the column headers of the table below by multiplying the applicable price in effect immediately before the adjustment by a fraction (A) whose numerator is the Conversion Rate
in effect immediately before the adjustment; and (B) whose denominator is the adjusted Conversion Rate. 
 In addition, the
Company shall adjust the number of additional shares in the table below in the same manner in which, and for the same events for which, the Company must adjust the Conversion Rate as described in Section 8(h).

 (v) The exact applicable share price and effective date may not be set forth in the table
above, in which case (A) if the actual applicable share price is between two applicable prices listed in the table above, or the actual effective date is between two dates listed in the table above, the Company 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; (B) if the actual
applicable price is greater than $90.00 per share (subject to adjustment), the Company shall not increase the Conversion Rate as described above and no additional shares shall be issuable upon conversion; and (C) if the actual applicable price
is less than $40.34 per share (subject to adjustment), the Company shall not increase the Conversion Rate as described above and no additional shares shall be issuable upon conversion. 

(vi) The Company shall not increase the Conversion Rate as described in this Section 8(k) of these Articles
Supplementary to the extent the increase will cause the Conversion Rate to exceed 0.6197, provided the Company shall adjust this maximum conversion rate in the same manner in which, and for the same events for which, the Company must adjust
the Conversion Rate as described in Section 8(h). 
 (l) Special Conversion Right of Series C Preferred Stock upon a
Fundamental Change; Company Repurchase Right. 
 (i) On or prior to April 10, 2014, in the event of a
Fundamental Change, when the applicable price of Common Stock described in Section 8(k)(iii) of these Articles Supplementary is less than $40.34 per share, then each holder of Series C Preferred Stock shall have the special right (the
“Fundamental Change Conversion Right”), in addition to any other applicable conversion right, to convert some or all of the Series C Preferred Stock on the relevant Fundamental Change Conversion Date into a number of shares of
Common Stock per $25.00 liquidation preference equal to such liquidation preference plus an amount equal to accrued and unpaid dividends to, but not including, such Fundamental Change Conversion Date, divided by 98% of the Market Price of Common
Stock (the “Fundamental Change Conversion Rate”). The Market Price of Common Stock shall be determined prior to the applicable Fundamental Change Conversion Date. A holder of Series C Preferred Stock which has elected to convert
such shares otherwise than pursuant to the Fundamental Change Conversion Right shall not be able to exercise the Fundamental Change Conversion Right. 
 (ii) If a holder of Series C Preferred Stock elects to convert Series C Preferred Stock as described in Section 8(l)(i) of these Articles Supplementary, the Company may elect, in lieu of that
conversion, to repurchase for cash some or all of such Series C Preferred Stock at a repurchase price (the “Fundamental Change Repurchase Price”) equal to 100% of the liquidation preference of the Series C Preferred Stock to be
repurchased plus an amount equal to accrued and unpaid dividends to, but not including, such Fundamental Change Conversion Date, or 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 Company shall pay such dividends to the holder of record on the corresponding Dividend Record Date, and the Fundamental Change Repurchase
Price shall be equal to 100% of the liquidation preference of the Series C Preferred Stock to be repurchased. 

 (iii) If the Company elects to repurchase Series C Preferred Stock that
would otherwise be converted into Common Stock on a Fundamental Change Conversion Date, such Series C Preferred Stock shall not be converted into Common Stock and the holder of such shares shall be entitled to receive the Fundamental Change
Repurchase Price in cash from the Company. 
 (iv) The aggregate number of shares of Common Stock issuable in
connection with the exercise of the Fundamental Change Conversion Right may not exceed 7.3 million shares of Common Stock (or 8.4 million shares of Common Stock if the underwriter of the Company’s offering of the Series C Preferred
Stock exercises its over-allotment option in full) or such other number of shares of Common Stock as shall then be authorized and available for issuance. If the number of shares of Common Stock issuable upon such conversion would exceed
7.3 million or 8.4 million shares of Common Stock, as the case may be, or such other number of shares of Common Stock as shall then be authorized and available for issuance, the Company shall have the option to satisfy the remainder of
such conversion in shares of Common Stock that are authorized for issuance in the future. The Company shall use its best efforts to have any such additional number of shares of Common Stock authorized for issuance within 180 days of the Fundamental
Change Conversion Date. 
 (v) Within 15 days after the occurrence of a Fundamental Change, the Company shall
provide to the holder of Series C Preferred Stock and the Company’s transfer agent a notice of the occurrence of the Fundamental Change and of the resulting repurchase right. Such notice shall state (A) the events constituting the
Fundamental Change; (B) the date of the Fundamental Change; (C) the last date on which the holder of Series C Preferred Stock may exercise the Fundamental Change Conversion Right; (D) to the extent applicable, the Fundamental Change
Conversion Rate and the Fundamental Change Repurchase Price; (E) that the Company may elect to repurchase some or all of the Series C Preferred Stock as to which the Fundamental Change Conversion Right may be exercised; (F) the method of
calculating the Market Price of Common Stock; (G) the Fundamental Change Conversion Date; (H) the name and address of the paying agent and the conversion agent; (I) the Conversion Rate and any adjustment to the Conversion Rate that
shall result from the Fundamental Change; (J) that Series C Preferred Stock as to which the Fundamental Change Conversion Right has been exercised may be converted at the applicable Conversion Rate, if otherwise convertible, only if the notice
of exercise of the Fundamental Change Conversion Right has been properly withdrawn; and (K) the procedures that the holder of Series C Preferred Stock must follow to exercise the Fundamental Change Conversion Right. 

(vi) The Company shall also issue a press release for publication on 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), or post notice on the Company’s website, in any event prior to the opening of business on the first Trading Day following any date on which the Company provides such notice to the holders of Series C Preferred Stock. 

(vii) The Fundamental Change Conversion Date shall be a date no less than 20 days nor more than 35 days after the date on
which the Company gives the notice described in Section 8(l)(v) of these Articles Supplementary. To exercise the Fundamental Change Conversion Right, the holder of Series C Preferred Stock shall deliver, on or before the close of business on
the Fundamental Change Conversion Date, the Series C Preferred Stock to be converted, duly endorsed for transfer, together with a written conversion notice completed, to the Company’s transfer agent. The conversion notice shall state
(A) the relevant Fundamental Change Conversion Date; (B) the number of Series C Preferred Stock to be converted; and (C) that the Series C Preferred Stock are to be converted pursuant to the applicable provisions of the Series C
Preferred Stock. Notwithstanding the foregoing, if the Series C Preferred Stock is held in global form, the conversion notice shall comply with applicable DTC procedures. 

(viii) Holders of Series C Preferred Stock may withdraw any notice of exercise of its Fundamental Change Conversion Right
(in whole or in part) by a written notice of withdrawal delivered to the Company’s transfer agent prior to the close of business on the business day prior to the Fundamental Change Conversion Date. The notice of withdrawal shall state
(A) the number of withdrawn shares of Series C Preferred Stock; (B) if certificated shares of Series C Preferred Stock have been issued, the certificate numbers of the withdrawn shares of Series C Preferred Stock; and (C) the number
of shares of 

 
the Series C Preferred Stock, if any, which remains subject to the conversion notice. Notwithstanding the foregoing, if the Series C Preferred Stock is held in global form, the notice of
withdrawal shall comply with applicable DTC procedures. 
 (ix) Series C Preferred Stock as to which the
Fundamental Change Conversion Right has been properly exercised and for which the conversion notice has not been properly withdrawn shall be converted into shares of Common Stock in accordance with the Fundamental Change Conversion Right on the
Fundamental Change Conversion Date, unless the Company has elected to repurchase such Series C Preferred Stock. 

(x) The holder of any shares of Series C Preferred Stock which the Company has elected to repurchase and as to which the
conversion election has not been properly withdrawn shall receive payment of the Fundamental Change Repurchase Price promptly following the later of the Fundamental Change Conversion Date or the time of book-entry transfer or delivery of the Series
C Preferred Stock. If the paying agent holds cash sufficient to pay the Fundamental Change Repurchase Price of the Series C Preferred Stock on the business day following the Fundamental Change Conversion Date, then (A) the Series C Preferred
Stock shall cease to be outstanding and dividends shall cease to accrue (whether or not book-entry transfer of the Series C Preferred Stock is made or whether or not the Series C Preferred Stock certificate is delivered to the Company’s
transfer agent); and (B) all of the other rights of the holder of Series C Preferred Stock shall terminate (other than the right to receive the Fundamental Change Repurchase Price upon delivery or transfer of the Series C Preferred Stock).

 SECTION 9. Record Holders. The Company and its transfer agent may deem and treat the record holder of any Series
C Preferred Stock as the true and lawful owner thereof for all purposes, and neither the Company nor its transfer agent shall be affected by any notice to the contrary. 
 SECTION 10. No Maturity or Sinking Fund. The Series C Preferred Stock has no maturity date, and no sinking fund has been established for the retirement or redemption of Series C Preferred
Stock; provided, however, that the Series C Preferred Stock owned by a stockholder in excess of the Ownership Limit shall be subject to the provisions of Section 5 and Section 7 of these Articles Supplementary. 

SECTION 11. Exclusion of Other Rights. The Series C Preferred Stock shall not have any preferences or other rights, voting
powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption other than expressly set forth in the Charter and these Articles Supplementary. 

SECTION 12. Headings of Subdivisions. The headings of the various subdivisions hereof are for convenience of reference only
and shall not affect the interpretation of any of the provisions hereof. 
 SECTION 13. Severability of Provisions.
If any preferences or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption of the Series C Preferred Stock set forth in the Charter and these Articles
Supplementary are invalid, unlawful or incapable of being enforced by reason of any rule of law or public policy, all other preferences or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications
or terms or conditions of redemption of Series C Preferred Stock set forth in the Charter which can be given effect without the invalid, unlawful or unenforceable provision thereof shall, nevertheless, remain in full force and effect and no
preferences or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption of the Series C Preferred Stock herein set forth shall be deemed dependent upon any
other provision thereof unless so expressed therein. 
 SECTION 14. No Preemptive Rights. No holder of Series C
Preferred Stock shall be entitled to any preemptive rights to subscribe for or acquire any unissued shares of capital stock of the Company (whether now or hereafter authorized) or securities of the Company convertible into or carrying a right to
subscribe to or acquire shares of capital stock of the Company.

 FEBRUARY 5, 2008 
 Digital Realty Trust, Inc., a Maryland corporation (the “Company”), hereby certifies to the State Department of Assessments and Taxation of Maryland (the “Department”)
that: 
 FIRST: Pursuant to the authority expressly vested in the Board of Directors of the Company (the “Board
of Directors”) by Article IV of the Articles of Amendment and Restatement of the Company filed with the Department on October 26, 2004 (the “Charter”) and Section 2-105 of
the Maryland General Corporation Law (the “MGCL”), the Board of Directors, by resolutions duly adopted on January 28, 2008, has authorized the classification and designation of up to 12,000,000 shares (plus up to an additional
15% to cover any underwriter over-allotment option) of the authorized but unissued preferred stock of the Company, par value $.01 per share (“Preferred Stock”), as a separate class of Preferred Stock, the issuance of a maximum of
12,000,000 shares (plus up to an additional 15% to cover any underwriter over-allotment option) of such class of Preferred Stock, and, pursuant to the powers contained in the Bylaws of the Company and the MGCL, appointed a committee (the
“Committee”) of the Board of Directors and delegated to the Committee, to the fullest extent permitted by the MGCL and the Charter and Bylaws of the Company, among other things, all powers of the Board of Directors with respect to
(i) setting the number of shares of the Preferred Stock to be classified and designated, up to a maximum of 12,000,000 shares (plus up to an additional 15% to cover any underwriter over-allotment option) of Preferred Stock, (ii) choosing
the cumulative dividend percentage for the Preferred Stock, (iii) selecting the dates on which dividends will be paid on the Preferred Stock, (iv) establishing the price per share for the Preferred Stock, (v) authorizing, approving

 SECOND: The Committee has unanimously adopted resolutions classifying and designating the
Preferred Stock as a separate class of Preferred Stock to be known as the “5.500% Series D Cumulative Convertible Preferred Stock,” setting the preferences, conversion and other rights, voting powers, restrictions, limitations as to
dividends and other distributions, transfers, qualifications, terms and conditions of redemption and other terms and conditions of such 5.500% Series D Cumulative Convertible Preferred Stock, and authorizing the issuance of up to 12,000,000 (plus up
to an additional 15% to cover any underwriter over-allotment option) shares of 5.500% Series D Cumulative Convertible Preferred Stock. 
 THIRD: The designation, number of shares, preferences, rights, voting powers, restrictions, limitations as to dividends and other distributions, qualifications, terms and conditions of redemption
and other terms and conditions of the separate class of Preferred Stock 

 
of the Company designated as 5.500% Series D Cumulative Convertible Preferred Stock are as follows (the “Series D Terms”), which upon any restatement of the Charter shall be made
a part of or incorporated by reference into the Charter with any necessary or appropriate changes to the enumeration or lettering of Sections or subsections thereof: 
 SECTION 1. Designation and Number. A series of Preferred Stock, designated the “5.500% Series D Cumulative Convertible Preferred Stock” (the “Series D Preferred Stock”),
is hereby established. The number of shares of Series D Preferred Stock shall be 13,800,000. 
 SECTION 2. Rank. The
Series D Preferred Stock will, with respect to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company, rank: (i) senior to all classes or series of the Company’s common stock, par
value $.01 per share (the “Common Stock”), and all classes or series of capital stock of the Company now or hereafter authorized, issued or outstanding expressly designated as ranking junior to the Series D Preferred Stock as to
dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company; (ii) on parity with the Series A Cumulative Redeemable Preferred Stock, par value $0.01 per share, the Series B Cumulative
Redeemable Preferred Stock, par value $0.01 per share, and the Series C Cumulative Convertible Preferred Stock, par value $0.01 per share, of the Company and with any class or series of capital stock of the Company expressly designated as ranking on
parity with the Series D Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company; and (iii) junior to any class or series of capital stock of the Company expressly
designated as ranking senior to the Series D Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company. The term “capital stock” does not include convertible
or exchangeable debt securities, which will rank senior to the Series D Preferred Stock prior to conversion or exchange. The Series D Preferred Stock will rank junior in right of payment to the Company’s other existing and future debt
obligations. 
 SECTION 3. Dividends. 
 (a) Subject to the preferential rights of the holders of any class or series of capital stock of the Company ranking senior to the Series D Preferred Stock as to dividends, the holders of shares of the
Series D Preferred Stock shall be entitled to receive, when, as and if authorized by the Board of Directors and declared by the Company, out of funds legally available for the payment of dividends, cumulative cash dividends at the rate of
5.500% per annum of the $25.00 liquidation preference per share of the Series D Preferred Stock (equivalent to the fixed annual amount of $1.375 per share of the Series D Preferred Stock). Such dividends shall accrue and be cumulative from and
including the first date on which any shares of Series D Preferred Stock are issued (the “Original Issue Date”) and shall be payable quarterly in arrears on each Dividend Payment Date (as defined below), commencing March 31,
2008; provided, however, that if any Dividend Payment Date is not a Business Day (as defined below), then the dividend which would otherwise have been payable on such Dividend Payment Date may be paid on the next succeeding Business
Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case 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 

  
 2 

 
Date to such next succeeding Business Day. The amount of any dividend payable on the Series D Preferred Stock for any partial Dividend Period (as defined below) shall be prorated and computed on
the basis of a 360-day year consisting of twelve 30-day months. Dividends will be payable to holders of record as they appear in the stockholder records of the Company
at the close of business on the applicable Dividend Record Date (as defined below). Notwithstanding any provision to the contrary contained herein, each outstanding share of Series D Preferred Stock shall be entitled to receive a dividend with
respect to any Dividend Record Date equal to the dividend paid with respect to each other share of Series D Preferred Stock that is outstanding on such date. “Dividend Record Date” shall mean the date designated by the Board of
Directors for the payment of dividends that is not more than 35 or fewer than 10 days prior to the applicable Dividend Payment Date. “Dividend Payment Date” shall mean the last calendar day of each March, June, September and
December, commencing on March 31, 2008. “Dividend Period” shall mean the respective periods commencing on and including the first day of January, April, July and October of each year and ending on and including the day
preceding the first day of the next succeeding Dividend Period (other than the initial Dividend Period, which shall commence on the Original Issue Date and end on and include March 31, 2008, and other than the Dividend Period during which any
shares of Series D Preferred Stock shall be redeemed pursuant to Section 5, which shall end on and include the day preceding the call date with respect to the shares of Series D Preferred Stock being redeemed). 

The term “Business Day” shall mean each day, other than a Saturday or a Sunday, which is not a day on which banking
institutions in New York, New York are authorized or required by law, regulation or executive order to close. 
 (b)
Notwithstanding anything contained herein to the contrary, dividends on the Series D Preferred Stock shall accrue whether or not the Company has earnings, whether or not there are funds legally available for the payment of such dividends, and
whether or not such dividends are authorized or declared. 
 (c) Except as provided in Section 3(d) below, no dividends
shall be declared and paid or declared and set apart for payment, and no other distribution of cash or other property may be declared and made, directly or indirectly, on or with respect to, any shares of Common Stock or shares of any other class or
series of capital stock of the Company ranking, as to dividends, on parity with or junior to the Series D Preferred Stock (other than a dividend paid in shares of Common Stock or in shares of any other class or series of capital stock ranking junior
to the Series D Preferred Stock as to dividends and upon liquidation) for any period, nor shall any shares of Common Stock or any other shares of any other class or series of capital stock of the Company ranking, as to dividends or upon liquidation,
on parity with or junior to the Series D Preferred Stock be redeemed, purchased or otherwise acquired for any consideration, nor shall any funds be paid or made available for a sinking fund for the redemption of such shares, and no other
distribution of cash or other property may be made, directly or indirectly, on or with respect thereto by the Company (except by conversion into or exchange for other shares of any class or series of capital stock of the Company ranking junior to
the Series D Preferred Stock as to dividends and upon liquidation, and except for the acquisition of shares made pursuant to the provisions of Article VI of the Charter or Section 7 hereof), unless full cumulative dividends on the Series D
Preferred Stock for all past dividend periods shall have been or contemporaneously 

  
 3 

 
are (i) declared and paid in cash or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for such payment. 

(d) When dividends are not paid in full (and a sum sufficient for such full payment is not so set apart) upon the Series D Preferred
Stock and the shares of any other class or series of capital stock ranking, as to dividends, on parity with the Series D Preferred Stock, all dividends declared upon the Series D Preferred Stock and each such other class or series of capital stock
ranking, as to dividends, on parity with the Series D Preferred Stock shall be declared pro rata so that the amount of dividends declared per share of Series D Preferred Stock and such other class or series of capital stock shall in all cases bear
to each other the same ratio that accrued dividends per share on the Series D Preferred Stock and such other class or series of capital stock (which shall not include any accrual in respect of unpaid dividends on such other class or series of
capital stock for prior dividend periods if such other class or series of capital stock does not have a cumulative dividend) bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or
payments on the Series D Preferred Stock which may be in arrears. 
 (e) Holders of shares of Series D Preferred Stock shall not
be entitled to any dividend, whether payable in cash, property or shares of stock, in excess of full cumulative dividends on the Series D Preferred Stock as provided herein. Any dividend payment made on the Series D Preferred Stock shall first be
credited against the earliest accrued but unpaid dividends due with respect to such shares which remains payable. Accrued but unpaid distributions on the Series D Preferred Stock will accumulate as of the Dividend Payment Date on which they first
become payable. 
 SECTION 4. Liquidation Preference. 

(a) Upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, before any distribution or
payment shall be made to holders of shares of Common Stock or any other class or series of capital stock of the Company ranking, as to rights upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company,
junior to the Series D Preferred Stock, the holders of shares of Series D Preferred Stock shall be entitled to be paid out of the assets of the Company legally available for distribution to its stockholders, after payment of or provision for the
debts and other liabilities of the Company, a liquidation preference of $25.00 per share, plus an amount equal to any accrued and unpaid dividends (whether or not authorized or declared) to but excluding the date of payment. In the event that, upon
such voluntary or involuntary liquidation, dissolution or winding up, the available assets of the Company are insufficient to pay the full amount of the liquidating distributions on all outstanding shares of Series D Preferred Stock and the
corresponding amounts payable on all shares of other classes or series of capital stock of the Company ranking, as to liquidation rights, on parity with the Series D Preferred Stock in the distribution of assets, then the holders of the Series D
Preferred Stock and each such other class or series of shares of capital stock ranking, as to voluntary or involuntary liquidation rights, on parity with the Series D Preferred Stock shall share ratably in any such distribution of assets in
proportion to the full liquidating distributions to which they would otherwise be respectively entitled. Written notice of any such voluntary or involuntary liquidation, dissolution or winding up of the Company, stating the payment date or dates
when, and the place or places where, the 

  
 4 

 
amounts distributable in such circumstances shall be payable, shall be given by first class mail, postage pre-paid, not fewer than 30 or more than 60 days
prior to the payment date stated therein, to each record holder of shares of Series D Preferred Stock at the respective addresses of such holders as the same shall appear on the stock transfer records of the Company. After payment of the full amount
of the liquidating distributions to which they are entitled, the holders of Series D Preferred Stock will have no right or claim to any of the remaining assets of the Company. The consolidation or merger of the Company with or into any other
corporation, trust or entity, or the voluntary sale, lease, transfer or conveyance of all or substantially all of the property or business of the Company, shall not be deemed to constitute a liquidation, dissolution or winding up of the affairs of
the Company. 
 (b) In determining whether a distribution (other than upon voluntary or involuntary liquidation), by dividend,
redemption or other acquisition of shares of capital stock of the Company or otherwise, is permitted under the MGCL, amounts that would be needed, if the Company were to be dissolved at the time of the distribution, to satisfy the preferential
rights upon dissolution of holders of shares of Series D Preferred Stock shall not be added to the Company’s total liabilities. 
 SECTION 5. Redemption. 
 (a) The Company shall have the right to redeem
shares of the Series D Preferred Stock in order to preserve the Company’s status as a REIT for federal tax purposes, in whole or in part, at any time or from time to time, for cash at a redemption price equal to 100% of the liquidation
preference of the Series D Preferred Stock to be redeemed plus an amount equal to all accrued and unpaid dividends up to, but not including, the date fixed for redemption, without interest; provided that if the redemption date is on a date that is
after a Dividend Record Date and on or prior to the corresponding Dividend Payment Date, the Company shall pay such dividends to the holder of record of such shares of Series D Preferred Stock on the Dividend Record Date, and the redemption price
shall be equal to 100% of the liquidation preference of the Series D Preferred Stock to be redeemed. 
 (b) If fewer than all of
the outstanding shares of Series D Preferred Stock are to be redeemed, the shares of Series D Preferred Stock to be redeemed shall be redeemed pro rata (as nearly as may be practicable without creating fractional shares) by lot or by any other
equitable method determined by the Company that will not result in a violation of the Ownership Limit and the Aggregate Stock Ownership Limit (each, as defined in Section 7(a)). If redemption is to be by lot and, as a result, any holder of
shares of Series D Preferred Stock would have actual ownership, Beneficial Ownership or Constructive Ownership (each, as defined in Section 7(a)) in excess of the Ownership Limit (as defined in Section 7(a)), the Aggregate Stock Ownership
Limit or such other limit as permitted by the Board of Directors or the Committee pursuant to Section 7(i) because such holder’s shares of Series D Preferred Stock were not redeemed, or were only redeemed in part, then, except as otherwise
provided in the Charter, the Company shall redeem the requisite number of shares of Series D Preferred Stock of such holder such that no holder will hold an amount of Series D Preferred Stock in excess of the applicable ownership limit subsequent to
such redemption. Holders of Series D Preferred Stock to be redeemed shall surrender such Series D Preferred Stock at the place designated in such notice and shall be entitled to the redemption price of $25.00 per share and any accrued and unpaid
dividends 

  
 5 

 
payable upon such redemption following such surrender. If (i) notice of redemption of any shares of Series D Preferred Stock has been given, (ii) the funds necessary for such redemption
have been set aside by the Company in trust for the benefit of the holders of any shares of Series D Preferred Stock so called for redemption, and (iii) irrevocable instructions have been given to pay the redemption price and all accrued and
unpaid dividends, then from and after the redemption date, dividends shall cease to accrue on such shares of Series D Preferred Stock, such shares of Series D Preferred Stock shall no longer be deemed outstanding, and all rights of the holders of
such shares shall terminate, except the right to receive the redemption price plus any accrued and unpaid dividends payable upon such redemption, without interest. So long as no dividends are in arrears, nothing herein shall prevent or restrict the
Company’s right or ability to purchase, from time to time, either at a public or a private sale, all or any part of the Series D Preferred Stock at such price or prices as the Company may determine, subject to the provisions of applicable law,
including the repurchase of shares of Series D Preferred Stock in open-market transactions duly authorized by the Board of Directors. 
 (c) [Intentionally Omitted.] 
 (d) [Intentionally Omitted.] 

(e) [Intentionally Omitted.] 
 (f) If a redemption date falls after a Dividend Record Date and on or prior to the corresponding Dividend Payment Date, each holder of Series D Preferred Stock at the close of business on such Dividend
Record Date shall be entitled to the dividend payable on such shares on the corresponding Dividend Payment Date notwithstanding the redemption of such shares on or prior to such Dividend Payment Date, and each holder of Series D Preferred Stock that
surrenders its shares on such redemption date will be entitled to the dividends accruing after the end of the Dividend Period to which such Dividend Payment Date relates up to but excluding the redemption date. Except as provided herein, the Company
shall make no payment or allowance for unpaid dividends, whether or not in arrears, on Series D Preferred Stock for which a notice of redemption has been given. 
 (g) All shares of the Series D Preferred Stock redeemed or repurchased pursuant to this Section 5 shall be retired and shall be restored to the status of authorized but unissued shares of Preferred
Stock, without designation as to series or class. 
 (h) The Series D Preferred Stock shall have no stated maturity and shall
not be subject to any sinking fund or mandatory redemption; provided, however, that the Series D Preferred Stock owned by a stockholder in excess of the Ownership Limit shall be subject to the provisions of this Section 5 and Section 7 of
these Articles Supplementary. 
 SECTION 6. Voting Rights. 

(a) Holders of the Series D Preferred Stock shall not have any voting rights, except as set forth in this Section 6. 

(b) Whenever dividends on any shares of Series D Preferred Stock shall be in arrears for six or more consecutive or non-consecutive quarterly periods (a “Preferred Dividend 

  
 6 

 
Default”), the holders of such Series D Preferred Stock (voting together as a single class with all other classes or series of preferred stock of the Company upon which like voting
rights have been conferred and are exercisable (“Parity Preferred”), including the Series A Cumulative Redeemable Preferred Stock, the Series B Cumulative Redeemable Preferred Stock and the Series C Cumulative Convertible Preferred
Stock of the Company) shall be entitled to vote for the election of a total of two additional directors of the Company (the “Preferred Directors”) until all dividends accumulated on such Series D Preferred Stock and Parity Preferred
for the past dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for payment. In such case, the entire Board of Directors will be increased by two directors. 

(c) The Preferred Directors will be elected by a plurality of the votes cast in the election for a
one-year term and each Preferred Director will serve until his or her successor is duly elected and qualifies or until such Preferred Director’s right to hold the office terminates, whichever occurs
earlier, subject to such Preferred Director’s earlier death, disqualification or removal. The election will take place at (i) either (a) a special meeting called in accordance with Section 6(d) below if the request is received
more than 90 days before the date fixed for the Company’s next annual or special meeting of stockholders or (b) the next annual or special meeting of stockholders if the request is received within 90 days of the date fixed for the
Company’s next annual or special meeting of stockholders, and (ii) at each subsequent annual meeting of stockholders, or special meeting held in place thereof, until all such dividends in arrears on the Series D Preferred Stock and each
such class or series of outstanding Parity Preferred have been paid in full. A dividend in respect of Series D Preferred Stock shall be considered timely made if made within two Business Days after the applicable Dividend Payment Date if at the time
of such late payment date there shall not be any prior quarterly dividend periods in respect of which full dividends were not timely made at the applicable Dividend Payment Date. 

(d) At any time when such voting rights shall have vested, a proper officer of the Company shall call or cause to be called, upon written
request of holders of record of at least 10% of the outstanding shares of Series D Preferred Stock and Parity Preferred, a special meeting of the holders of Series D Preferred Stock and each class or series of Parity Preferred by mailing or causing
to be mailed to such holders a notice of such special meeting to be held not fewer than ten or more than 45 days after the date such notice is given. The record date for determining holders of the Series D Preferred Stock and Parity Preferred
entitled to notice of and to vote at such special meeting will be the close of business on the third Business Day preceding the day on which such notice is mailed. At any such annual or special meeting, all of the holders of the Series D Preferred
Stock and Parity Preferred, by plurality vote, voting together as a single class without regard to class or series will be entitled to elect two directors on the basis of one vote per $25.00 of liquidation preference to which such Series D Preferred
Stock and Parity Preferred are entitled by their terms (excluding amounts in respect of accumulated and unpaid dividends) and not cumulatively. The holder or holders of one-third of the Series D Preferred
Stock and Parity Preferred voting as a single class then outstanding, present in person or by proxy, will constitute a quorum for the election of the Preferred Directors except as otherwise provided by law. Notice of all meetings at which holders of
the Series D Preferred Stock and the Parity Preferred shall be entitled to vote will be given to such holders at their addresses as they appear in the transfer records. At any such meeting or adjournment thereof in the absence of a

  
 7 

 
quorum, subject to the provisions of any applicable law, a majority of the holders of the Series D Preferred Stock and Parity Preferred voting as a single class present in person or by proxy
shall have the power to adjourn the meeting for the election of the Preferred Directors, without notice other than an announcement at the meeting, until a quorum is present. If a Preferred Dividend Default shall terminate after the notice of a
special meeting has been given but before such special meeting has been held, the Company shall, as soon as practicable after such termination, mail or cause to be mailed notice of such termination to holders of the Series D Preferred Stock and the
Parity Preferred that would have been entitled to vote at such special meeting. 
 (e) If and when all accumulated dividends on
such Series D Preferred Stock and all classes or series of Parity Preferred for the past dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for payment, the right of the holders of Series D
Preferred Stock and the Parity Preferred to elect such additional two directors shall immediately cease (subject to revesting in the event of each and every Preferred Dividend Default), and the term of office of each Preferred Director so elected
shall terminate and the entire Board of Directors shall be reduced accordingly. Any Preferred Director may be removed at any time with or without cause by the vote of, and shall not be removed otherwise than by the vote of, the holders of record of
a majority of the outstanding Series D Preferred Stock and the Parity Preferred entitled to vote thereon when they have the voting rights set forth in Section 6(b) (voting as a single class). So long as a Preferred Dividend Default shall
continue, any vacancy in the office of a Preferred Director may be filled by written consent of the Preferred Director remaining in office, or if none remains in office, by a vote of the holders of record of a majority of the outstanding Series D
Preferred Stock when they have the voting rights described above (voting as a single class with all other classes or series of Parity Preferred). Each of the Preferred Directors shall be entitled to one vote on any matter. 

(f) So long as any shares of Series D Preferred Stock remain outstanding, the affirmative vote or consent of the holders of two-thirds of the shares of Series D Preferred Stock and each other class or series of preferred stock ranking on parity with the Series D Preferred Stock with respect to the payment of dividends and the
distribution of assets upon liquidation, dissolution or winding up of the Company upon which like voting rights have been conferred outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting as a single class)
will be required to: (i) authorize, create or issue, or increase the number of authorized or issued shares of, any class or series of capital stock ranking senior to the Series D Preferred Stock with respect to payment of dividends or the
distribution of assets upon liquidation, dissolution or winding up of the affairs of the Company or reclassify any authorized shares of capital stock of the Company into such capital stock, or create, authorize or issue any obligation or security
convertible into or evidencing the right to purchase any such capital stock; or (ii) amend, alter or repeal the provisions of the Charter or the terms of the Series D Preferred Stock, whether by merger, consolidation, transfer or conveyance of
all or substantially all of its assets or otherwise (an “Event”), so as to materially and adversely affect any right, preference, privilege or voting power of the Series D Preferred Stock; provided however, with respect to
the occurrence of any of the Events set forth in (ii) above, so long as the Series D Preferred Stock remains outstanding with the terms thereof materially unchanged, taking into account that, upon the occurrence of an Event, the Company may not
be the surviving entity, the occurrence of such Event shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting power of Series D Preferred Stock, and in such case such holders shall not have any

  
 8 

 
voting rights with respect to the occurrence of any of the Events set forth in (ii) above. In addition, if the holders of the Series D Preferred Stock receive the greater of the full trading
price of the Series D Preferred Stock on the date of an Event set forth in (ii) above or the $25.00 liquidation preference per share of the Series D Preferred Stock pursuant to the occurrence of any of the Events set forth in (ii) above,
then such holders shall not have any voting rights with respect to the Events set forth in (ii) above. Holders of shares of Series D Preferred Stock shall not be entitled to vote with respect to: (a) any increase in the total number of
authorized shares of Common Stock or Preferred Stock of the Company, or (b) any increase in the number of authorized shares of Series D Preferred Stock or the creation or issuance of any other class or series of capital stock, or (c) any
increase in the number of authorized shares of any other class or series of capital stock, in each case referred to in clause (a), (b) or (c) above ranking on parity with or junior to the Series D Preferred Stock with respect to the
payment of dividends and the distribution of assets upon liquidation, dissolution or winding up of the Company. Except as set forth herein, holders of the Series D Preferred Stock shall not have any voting rights with respect to, and the consent of
the holders of the Series D Preferred Stock shall not be required for, the taking of any corporate action, including an Event, regardless of the effect that such corporate action or Event may have upon the powers, preferences, voting power or other
rights or privileges of the Series D Preferred Stock. 
 (g) The foregoing voting provisions of this Section 6 shall not
apply if, at or prior to the time when the act with respect to which such vote would otherwise be required shall be effected, all outstanding shares of Series D Preferred Stock shall have been redeemed or called for redemption upon proper notice and
sufficient funds, in cash, shall have been deposited in trust to effect such redemption. 
 (h) In any matter in which the
Series D Preferred Stock may vote (as expressly provided herein), each share of Series D Preferred Stock shall be entitled to one vote per $25.00 of liquidation preference.

shares of Series D Preferred Stock to the Trust) and (ii) the price per share received by the Trustee (net of any commissions and other expenses of sale) from the sale or other disposition of the shares of Series D Preferred Stock held in the
Trust. The Trustee may reduce the amount payable to the Purported Record Transferee by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee
pursuant to Section 7(c)(iii). Any net sales proceeds in excess of the amount payable to the Purported Record Transferee shall be immediately paid to the Charitable Beneficiary together with any dividends or other distributions thereon. If,
prior to the discovery by the Company that shares of such Series D Preferred Stock have been transferred to the Trustee, such shares of Series D Preferred Stock are sold by a Purported Record Transferee then (i) such shares of Series D
Preferred Stock shall be deemed to have been sold on behalf of the Trust and (ii) to the extent that the Purported Record Transferee received an amount for such shares of Series D Preferred Stock that exceeds the amount that such Purported
Record Transferee was entitled to receive pursuant to this Section 7(c)(iv), such excess shall be paid to the Trustee upon demand. 
 (v) Series D Preferred Stock transferred to the Trustee shall be deemed to have been offered for sale to the Company, or its designee, at a price per share equal to the lesser of (i) the price paid
by the Purported Record Transferee for the shares of Series D Preferred Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of
Series D Preferred Stock at Market Price, the Market Price of such shares of Series D Preferred Stock on the day of the event which resulted in the transfer of such shares of Series D Preferred Stock to the Trust) and (ii) the Market Price on
the date the Company, or its designee, accepts such offer. The Company may reduce the amount payable to the Purported Record Transferee by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed
by the Purported Record Transferee to the Trustee pursuant to Section 7(c)(iii). The Company shall have the right to accept such offer until the Trustee has sold the shares of Series D Preferred Stock held in the Trust pursuant to
Section 7(c)(iv). Upon such a sale to the Company, the interest of the Charitable Beneficiary in the shares of Series D Preferred Stock sold shall terminate and the Trustee shall distribute the net proceeds of the sale to the Purported Record
Transferee and any dividends or other distributions held by the Trustee with respect to such Series D Preferred Stock shall thereupon be paid to the Charitable Beneficiary. 

(vi) By written notice to the Trustee, the Company shall designate one or more nonprofit organizations to be the
Charitable Beneficiary of the interest in the Trust such that the Series D Preferred Stock held in the Trust would not violate the restrictions set forth in Section 7(b)(i) in the hands of such Charitable Beneficiary.

 (d) Remedies For Breach. If the Board of Directors or a committee thereof or other
designees if permitted by the MGCL shall at any time determine in good faith that a Transfer or other event has taken place in violation of Section 7(b) of these Articles Supplementary or that a Person intends to acquire, has attempted to
acquire or may acquire beneficial ownership (determined without reference to any rules of attribution), Beneficial Ownership or Constructive Ownership of any shares of Series D Preferred Stock of the Company in violation of Section 7(b) of
these Articles Supplementary, the Board of Directors or the Committee or other designees if permitted by the MGCL shall take such action as it deems advisable to refuse to give effect or to prevent such Transfer, including, but not limited to,
causing the Company to redeem shares of Series D Preferred Stock, refusing to give effect to such Transfer on the books of the Company or instituting proceedings to enjoin such Transfer; provided, however, that any Transfers (or, in the case of
events other than a Transfer, ownership or Constructive Ownership or Beneficial Ownership) in violation of Section 7(b)(i) of these Articles Supplementary, shall automatically result in the transfer to a Trust as described in
Section 7(b)(ii) and any Transfer in violation of Section 7(b)(iii) shall automatically be void ab initio irrespective of any action (or non-action) by the Board of Directors. 

(e) Notice of Restricted Transfer. Any Person who acquires or attempts to acquire shares of Series D Preferred Stock in violation
of Section 7(b) of these Articles Supplementary, or any Person who is a Purported Beneficial Transferee such that an automatic transfer to a Trust results under Section 7(b)(ii) of these Articles Supplementary, shall immediately give
written notice to the Company of such event and shall provide to the Company such other information as the Company may request in order to determine the effect, if any of such Transfer or attempted Transfer on the Company’s status as a REIT.

owner or Beneficial Owner or Constructive Owner of Series D Preferred Stock and each Person (including the stockholder of record) who is holding Series D Preferred Stock for a beneficial owner or Beneficial Owner or Constructive Owner shall provide
to the Company such information that the Company may request, in good faith, in order to determine the Company’s status as a REIT. 
 (g) Remedies Not Limited. Nothing contained in these Articles Supplementary (but subject to Section 7(l) of these Articles Supplementary) shall limit the authority of the Board of Directors to
take such other action as it deems necessary or advisable to protect the Company and the interests of its stockholders by preservation of the Company’s status as a REIT. 
 (h) Ambiguity. In the case of an ambiguity in the application of any of the provisions of this Section 7 of these Articles Supplementary, including any definition contained in
Section 7(a), the Board of Directors shall have the power to determine the application of the provisions of this Section 7 with respect to any situation based on the facts known to it (subject, however, to the provisions of
Section 7(l) of these Articles Supplementary). In the event Section 7 requires an action by the Board of Directors and these Articles Supplementary fail to provide specific guidance with respect to such action, the Board of Directors shall
have the power to 

  
 15 

 
determine the action to be taken so long as such action is not contrary to the provisions of Section 7. Absent a decision to the contrary by the Board of Directors (which the Board of
Directors may make in its sole and absolute discretion), if a Person would have (but for the remedies set forth in Section 7(b)) acquired Beneficial or Constructive Ownership of Series D Preferred Stock in violation of Section 7(b)(i),
such remedies (as applicable) shall apply first to the shares of Series D Preferred Stock which, but for such remedies, would have been actually owned by such Person, and second to shares of Series D Preferred Stock, which, but for such remedies,
would have been Beneficially Owned or Constructively Owned (but not actually owned) by such Person, pro rata among the Persons who actually own such shares of Series D Preferred Stock based upon the relative number of the shares of Series D
Preferred Stock held by each such Person. 
 (i) Exceptions. 

(i) Subject to Section 7(b)(i)(D), the Board of Directors, in its sole discretion, may exempt (prospectively or
retroactively) a Person from the limitation on a Person Beneficially Owning shares of Series D Preferred Stock in violation of Section 7(b)(i)(A) or Section 7(b)(i)(C) if the Board of Directors determines that such exemption will not cause
any Individual’s Beneficial Ownership of shares of Capital Stock to violate the Aggregate Stock Ownership Limit and that such exemption will not cause the Company to fail to qualify as a REIT under the Code. 

(ii) Subject to Section 7(b)(i)(D), the Board of Directors, in its sole discretion, may exempt (prospectively or
retroactively) a Person from the limitation on a Person Constructively Owning shares of Series D Preferred Stock in violation of Section 7(b)(i)(B) or Section 7(b)(i)(C) if the Board of Directors determines that such ownership would not
cause the Company to fail to qualify as a REIT under the Code. 
 (iii) Subject to Section 7(b)(i)(D) and
the remainder of this Section 7(i)(iii), the Board of Directors may from time to time increase or decrease the Ownership Limit; provided, however, that the decreased Ownership Limit will not be effective for any Person whose percentage
ownership of Series D Preferred Stock is in excess of such decreased Ownership Limit until such time as such Person’s percentage of Series D Preferred Stock equals or falls below the decreased Ownership Limit, but any further acquisition of
Series D Preferred Stock in excess of such percentage ownership of Series D Preferred Stock will be in violation of the Ownership Limit, and, provided further, that the new Ownership Limit would not allow five or fewer Persons to Beneficially Own
more than 49% in value of the outstanding capital stock of the Company. 
 (iv) In granting a person an exemption
under Section 7(i)(i) or (ii) above, the Board of Directors may require such Person to make certain representations or undertakings or to agree that any violation or attempted violation of such representations or undertakings (or other
action which is contrary to the restrictions contained in Section 7(b) of these Articles Supplementary) will result in such Series D Preferred Stock being transferred to a Trust in accordance with Section 7(b)(ii) of these Articles
Supplementary. In granting any exception pursuant to Section 7(i)(i) or (ii) of these Articles Supplementary, the Board of Directors may require a ruling from the IRS, or an opinion 

  
 16 

 
of counsel, in either case in form and substance satisfactory to the Board of Directors in its sole discretion, as it may deem necessary or advisable in order to determine or ensure the
Company’s status as a REIT. 
 (j) Legends. Each certificate for Series D Preferred Stock shall bear substantially
the following legends in addition to any legends required to comply with federal and state securities laws:

 “THE COMPANY IS AUTHORIZED TO ISSUE CAPITAL STOCK OF MORE THAN ONE CLASS, CONSISTING OF COMMON STOCK AND ONE OR MORE

(iv) NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SERIES D PREFERRED STOCK THAT, TAKING INTO ACCOUNT ANY OTHER CAPITAL STOCK OF THE COMPANY BENEFICIALLY OR CONSTRUCTIVELY OWNED BY SUCH PERSON, WOULD RESULT IN THE COMPANY BEING “CLOSELY

INCLUDING THE RESTRICTIONS ON TRANSFER AND OWNERSHIP, WILL BE FURNISHED TO EACH HOLDER OF SERIES D PREFERRED STOCK ON REQUEST AND WITHOUT CHARGE. REQUESTS FOR SUCH A COPY MAY BE DIRECTED TO THE SECRETARY OF THE COMPANY AT ITS PRINCIPAL OFFICE.”

 (k) Severability. If any provision of this Section 7 or any application of any such provision is determined to be
invalid by any federal or state court having jurisdiction over the issues, the validity of the remaining provisions shall not be affected and other applications of such provision shall be affected only to the extent necessary to comply with the
determination of such court. 

  
 18 

 (l) NYSE. Nothing in this Section 7 shall preclude the settlement of any
transaction entered into through the facilities of the NYSE. The shares of Series D Preferred Stock that are the subject of such transaction shall continue to be subject to the provisions of this Section 7 after such settlement. 

(m) Applicability of Section 7. The provisions set forth in this Section 7 shall apply to the Series D Preferred Stock
notwithstanding any contrary provisions of the Series D Preferred Stock provided for elsewhere in these Articles Supplementary. 

SECTION 8. Conversion Rights. 
 (a) Definitions. For the purposes of this Section 8 of these Articles Supplementary, the following terms shall have the following meanings: 

“Closing Sale Price” per share of Common Stock on any date means the closing sale price per share (or, if no closing
sale price is reported, the average of the bid and asked prices or, if more than one in either case, the average of the average bid and the average asked prices) on such date as reported by the NYSE or, if the Common Stock is not reported by the
NYSE, in composite transactions for the principal other U.S. national or regional securities exchange on which the Common Stock is traded. If the Common Stock is not listed for trading on a U.S. national or regional securities exchange on the
relevant date, the “Closing Sale Price” will be the last quoted bid price for the Common Stock in the over-the-counter market on the relevant date as reported
by the National Quotation Bureau Incorporated or similar organization. If the Common Stock is not so quoted, the “Closing Sale Price” will be the average of the mid-point of the last bid and asked
prices for the Common Stock on the relevant date from each of at least three independent nationally recognized investment banking firms selected by the Company for this purpose. 

“Conversion Date” has the meaning set forth in Section 8(b)(ii) of these Articles Supplementary. 

“Conversion Option” means the Company’s option to convert some or all of the Series D Preferred Stock into that
number of shares of Common Stock that are issuable at the then-applicable conversion rate as described in Section 8(c) of these Articles Supplementary.

Conversion Rate. 
 “Conversion Rate” means initially 0.5955 shares of Common Stock per $25.00 liquidation
preference, subject to adjustment in certain events as set forth in this Section 8 of these Articles Supplementary. 

“DTC” means The Depository Trust Company or any successor entity. 

  
 19 

 “Fundamental Change” shall be deemed to have occurred at such time as:

 (i) the consummation of any transaction or event (whether by means of a share exchange or tender offer
applicable to Common Stock, a liquidation, consolidation, recapitalization, reclassification, combination or merger of the Company or a sale, lease or other transfer of all or substantially all of its consolidated assets) or a series of related
transactions or events pursuant to which all of the outstanding shares of Common Stock are exchanged for, converted into or constitutes solely the right to receive cash, securities or other property more than 10% of which consists of cash,
securities or other property that are not, or upon issuance will not be, traded on a national securities exchange; 
 (ii) any “person” or “group” (as such terms are used for purposes of Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended, whether or not applicable), other than
the Company, the Company’s operating partnership subsidiary, Digital Realty Trust, L.P. (the “Operating Partnership”) or any of the Company’s or the Operating Partnership’s majority-owned subsidiaries or any employee
benefit plan of the Company, the Operating Partnership or such subsidiary, is or becomes the “beneficial owner,” directly or indirectly, of more than 50% of the total voting power in the aggregate of all classes of the Company’s
capital stock of then outstanding entitled to vote generally in elections of directors (for the avoidance of doubt the ownership of limited partnership units of the Operating Partnership shall not be deemed to constitute beneficial ownership of the
Company’s capital stock); or 
 (iii) during any period of 12 consecutive months after the date of original
issuance of the Series D Preferred Stock, persons who at the beginning of such 12 month period constituted the Company’s board of directors, together with any new persons whose election was approved by a vote of a majority of the persons then
still comprising the Company’s board of directors who were either members of the board of directors at the beginning of such period or whose election, designation or nomination for election was previously so approved, cease for any reason to
constitute a majority of the Company’s board of directors. 
 “Fundamental Change Conversion Right” has
the meaning set forth in Section 8(l)(i) of these Articles Supplementary. 
 “Market Price” means, with
respect to any Fundamental Change Conversion Date, the average of the Closing Sale Prices of the Common Stock for the ten consecutive Trading Days ending on the third Trading Day prior to the Fundamental Change Conversion Date, appropriately
adjusted to take into account the occurrence, during the period commencing on the first Trading Day of such ten Trading Day period and ending on the Fundamental Change Conversion Date of any event requiring an adjustment of the Conversion Rate as
described under Section 8(h); provided that in no event shall the market price be less than $0.01, subject to adjustment for share splits and combinations, reclassifications and similar events. 

“NYSE” means the New York Stock Exchange, Inc. 
 “SEC” means the U.S. Securities and Exchange Commission. 

  
 20 

 “Trading Day” means a day during which trading in securities generally
occurs on the NYSE or, if the Common Stock is not quoted on the NYSE, then a day during which trading in securities generally occurs on the principal U.S. securities exchange on which the Common Stock is listed or, if the Common Stock is not listed
on a U.S. national or regional securities exchange, then on the principal other market on which the Common Stock is then traded or quoted. 
 (b) Conversion at Holder’s Option. 
 (i) Holders of
shares of Series D Preferred Stock, at their option, may, at any time and from time to time, convert some or all of their outstanding shares of Series D Preferred Stock into Common Stock at the then applicable Conversion Rate. 

(ii) The Company shall not issue fractional shares of Common Stock upon the conversion of shares of Series D Preferred
Stock. Instead, the Company shall pay the cash value of such fractional shares based upon the Closing Sale Price of its Common Stock on the Trading Day (as defined in this Section 8) immediately prior to (A) the date on which the
certificate or certificates representing the shares of Series D Preferred Stock to be converted are surrendered, accompanied by a written notice of conversion and any required transfer taxes (the “Conversion Date”), or (B) the
effective date for the Company’s Conversion Option, as the case may be. 
 (iii) A holder of shares of
Series D Preferred Stock is not entitled to any rights of a common stockholder of the Company until such holder of shares of Series D Preferred Stock has converted its shares of Series D Preferred Stock or unless the Company has exercised its
Conversion Option, and only to the extent the shares of Series D Preferred Stock are deemed to have been converted into shares of Common Stock under these Articles Supplementary. 

(iv) Notwithstanding anything herein to the contrary, holders of shares of Series D Preferred Stock may not convert their
outstanding shares of Series D Preferred Stock into Common Stock if such conversion would cause the holder to violate the Aggregate Stock Ownership Limit or Common Stock Ownership Limit or otherwise result in the Company failing to qualify as a
REIT. 
 (v) Conversion Procedures. Holders of shares of Series D Preferred Stock may convert some or all
of their shares by surrendering to the Company at its principal office or at the office of its transfer agent, as may be designated by the Board of Directors, the certificate or certificates for the shares of Series D Preferred Stock to be
converted, accompanied by a written notice stating that the holder of shares of Series D Preferred Stock elects to convert all or a specified whole number of those shares in accordance with the provisions described in this Section 8 and
specifying the name or names in which the holder of shares of Series D Preferred Stock wishes the certificate or certificates for the shares of Common Stock to be issued. If the notice specifies a name or names other than the name of the holder of
shares of Series D Preferred Stock, the notice shall be accompanied by payment of all transfer taxes payable upon the issuance of shares of Common Stock in that name or names. Other than such transfer taxes, the

  
 21 

 
Company shall pay any documentary, stamp or similar issue or transfer taxes that may be payable in respect of any issuance or delivery of shares of Common Stock upon conversion of shares of
Series D Preferred Stock. The date on which the Company has received all of the surrendered certificate or certificates, the notice relating to the conversion and payment of all required transfer taxes, if any, or the demonstration to the
Company’s satisfaction that those taxes have been paid, shall be deemed the Conversion Date with respect to a share of Series D Preferred Stock. As promptly as practicable after the Conversion Date with respect to any shares of Series D
Preferred Stock, the Company shall deliver or cause to be delivered (A) certificates representing the number of validly issued, fully paid and non-assessable shares of Common Stock to which the holders of
shares of such Series D Preferred Stock, or the transferee of the holder of such shares of Series D Preferred Stock, shall be entitled and (B) if less than the full number of shares of Series D Preferred Stock represented by the surrendered
certificate or certificates is being converted, a new certificate or certificates, of like tenor, for the number of shares represented by the surrendered certificate or certificates, less the number of shares being converted. This conversion shall
be deemed to have been made at the close of business on the Conversion Date so that the rights of the holder of shares of Series D Preferred Stock as to the shares being converted shall cease except for the right to receive the conversion value,
and, if applicable, the person entitled to receive shares of Common Stock shall be treated for all purposes as having become the record holder of those shares of Common Stock at that time on that date. 

(vi) In lieu of the foregoing procedures, if the Series D Preferred Stock is held in global certificate form, the holder
of shares of Series D Preferred Stock must comply with the procedures of DTC to convert its beneficial interest in respect of the Series D Preferred Stock represented by a global stock certificate of the Series D Preferred Stock. 

(vii) If any shares of Series D Preferred Stock are to be converted pursuant to the Company’s Conversion Option, the
right of a holder of such to voluntarily convert those shares of Series D Preferred Stock shall terminate if the Company has not received the conversion notice of such holder of such shares of Series D Preferred Stock by 5:00 p.m., New York City
time, on the business day immediately preceding the date fixed for conversion pursuant to the Company’s Conversion Option. 
 (viii) If more than one share of Series D Preferred Stock is surrendered for conversion by the same holder at the same time, the number of whole shares of Common Stock issuable upon conversion of those
shares of Series D Preferred Stock shall be computed on the basis of the total number of shares of Series D Preferred Stock so surrendered. 
 (c) Company Conversion Option. 
 (i) On or after
February 6, 2013, the Company may exercise its Conversion Option, as described below, but only if (A) the Closing Sale Price of the Common Stock equals or exceeds 130% of the then-applicable Conversion Price per share of the Series D
Preferred Stock 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 

  
 22 

 
prior to the Company’s issuance of a press release announcing the exercise of its Conversion Option as described below in paragraph (iii); and (B) on or prior to the Effective Date of
the exercise of its Conversion Option, the Company has either declared and paid, or declared and set apart for payment, any unpaid dividends that are in arrears on the Series D Preferred Stock. 

(ii) If the Company converts less than all of the outstanding shares of Series D Preferred Stock, the Company’s
transfer agent shall select the shares by lot, on a pro rata basis or in accordance with any other method the transfer agent considers fair and appropriate. The Company may convert the Series D Preferred Stock only in a whole number of shares of
Series D Preferred Stock. If a portion of a holder’s Series D Preferred Stock is selected for partial conversion by the Company and the holder converts a portion of such Series D Preferred Stock, the number of shares of Series D Preferred Stock
subject to conversion by the Company shall be reduced by the number of shares that the holder converted. 
 (iii)
To exercise its Conversion Option described above, the Company shall issue a press release for publication on 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 conditions described in Section 8(c)(i) are met, announcing such conversion. The Company shall also give notice by mail or by publication (with subsequent prompt notice by mail) to holders of shares of Series D Preferred Stock (not
more than four Trading Days after the date of the press release) and, if required by the rules and regulations of the SEC, the Company shall file a Current Report on Form 8-K (or make such other filing on an
appropriate form as may be permitted by the rules and regulations of the SEC), of the exercise of the Company’s Conversion Option announcing its intention to convert Series D Preferred Stock. The Effective Date for the Company’s Conversion
Option shall be the date that is five Trading Days after the date on which the Company issues such press release. 
 (iv) In addition to any information required by applicable law or regulation, the press release and notice of the exercise of the Company’s Conversion Option referred to in paragraph (iii) above
shall state, as appropriate: (A) the Effective Date for its Conversion Option; (B) the number of shares of Common Stock to be issued upon conversion of each share of Series D Preferred Stock; (C) the number of shares of Series D
Preferred Stock to be converted; and (D) that dividends on the shares of Series D Preferred Stock to be converted shall cease to accrue on the Effective Date for the Company’s Conversion Option (and no dividends on such converted shares
shall be payable except as provided in these Articles Supplementary). 
 (d) Reservation of Shares. The Company shall at
all times reserve and keep available, free from preemptive rights out of the Company’s authorized but unissued shares of capital stock, for issuance upon the conversion of shares of Series D Preferred Stock, a number

  
 23 

 
of the Company’s authorized but unissued shares of Common Stock that shall from time to time be sufficient to permit the conversion of all outstanding shares of Series D Preferred Stock.

 (e) Compliance with Laws; Validity, etc., of Common Stock. Before the delivery of any securities upon conversion of
shares of Series D Preferred Stock, the Company shall comply with all applicable federal and state laws and regulations. All shares of Common Stock delivered upon conversion of shares of Series D Preferred Stock shall, upon delivery, be duly and
validly issued, fully paid and non-assessable, free of all liens and charges and not subject to any preemptive rights. 
 (f) Payment of Dividends Upon Conversion; Optional Conversion. 
 (i) If a holder of shares of Series D Preferred Stock exercises its conversion rights, upon delivery of the shares of Series D Preferred Stock for conversion, those shares of Series D Preferred Stock
shall cease to cumulate dividends as of the end of the Conversion Date, and the holder of shares of Series D Preferred Stock shall not receive any cash payment in an amount equal to accrued and unpaid dividends on the shares of Series D Preferred
Stock, except in those limited circumstances discussed below in this Section 8(f). Except as provided below in this Section 8(f), the Company shall make no payment for accrued and unpaid dividends, whether or not in arrears, on shares of
Series D Preferred Stock converted at the election of holders of such shares. 
 (ii) If the Company receives a
conversion notice before the close of business on a Dividend Record Date, the holder of shares of Series D Preferred Stock shall not be entitled to receive any portion of the dividend payable on such shares of converted stock on the corresponding
Dividend Payment Date. 
 (iii) If the Company receives a conversion notice after the Dividend Record Date but
prior to the corresponding Dividend Payment Date, the holder of shares of Series D Preferred Stock on the Dividend Record Date will receive on that Dividend Payment Date accrued dividends on those shares of Series D Preferred Stock, notwithstanding
the conversion of those shares of Series D Preferred Stock prior to that Dividend Payment Date, because that holder of shares of Series D Preferred Stock will have been the holder of record of shares of Series D Preferred Stock on the corresponding
Dividend Record Date. At the time that such holder of shares of Series D Preferred Stock surrenders shares of Series D Preferred Stock for conversion, however, it shall pay to the Company an amount equal to the dividend that has accrued and that
will be paid on the related Dividend Payment Date; provided that no such payment need be made if the Company has specified a Fundamental Change Repurchase Date relating to a Fundamental Change that is after a Dividend Record Date and on or prior to
the Dividend Payment Date to which that Dividend Record Date relates. 
 (iv) If the holder of shares of Series D
Preferred Stock is a holder of shares of Series D Preferred Stock on a Dividend Record Date and converts such shares of Series D Preferred Stock into shares of Common Stock on or after the corresponding Dividend Payment Date such holder of shares of
Series D Preferred Stock shall be entitled to receive the dividend payable on such shares of Series D Preferred Stock on such 

  
 24 

 
corresponding Dividend Payment Date, and the holder of shares of Series D Preferred Stock shall not need to include payment of the amount of such dividend upon surrender for conversion of shares
of Series D Preferred Stock. 
 (g) Payment of Dividends Upon Conversion; Company Conversion Option. 

(i) If the Company converts shares of Series D Preferred Stock pursuant to its Conversion Option, on or prior to the
Effective Date of the Conversion Option, the Company must first declare and pay, or declare and set apart for payment, any unpaid dividends that are in arrears on Series D Preferred Stock. 

(ii) If the Company exercises its Conversion Option and the Effective Date 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 shares of Series D Preferred Stock shall not be entitled to receive any portion of the dividend payable for such period on such converted shares on the
corresponding Dividend Payment Date. Accordingly, if the Company converts shares of Series D Preferred Stock and the effective date is after the close of business on a Dividend Payment Date and prior to the close of business on the next Dividend
Record Date, holders of shares of Series D Preferred Stock shall forego the right to receive any dividends accruing from such Dividend Payment Date to the Effective Date. 

(iii) If the Company exercises its Conversion Option and the Effective Date 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 payable for such period with respect to the shares of Series D Preferred Stock called for a conversion on such date, shall be payable
on such Dividend Payment Date to the holder of such shares of Series D Preferred Stock on such Dividend Record Date. 
 (h)
Conversion Rate Adjustments. The Company shall adjust the conversion rate from time to time as follows: 

(i) If the Company issues shares of Common Stock as a dividend or distribution on shares of Common Stock to all holders of
Common Stock, or if the Company effects a share split or share combination, the conversion rate shall be adjusted based on the following formula: 
 CR1 = CR0 x OS1/OS0 
 where

 CR0 = the conversion rate in effect immediately prior to the ex-dividend date for such
dividend or distribution, or the effective date of such share split or share combination; 

  
 25 

 CR1 = the new conversion rate in effect immediately on and after the ex-dividend date
for such dividend or distribution, or the effective date of such share split or share combination; 

OS1 = the number of shares of Common Stock outstanding immediately after such dividend or distribution, or the effective date
of such share split or share combination; and 

OS0 = the number of shares of Common Stock outstanding immediately prior to such dividend or distribution, or the effective
date of such share split or share combination. 
 Any adjustment made pursuant to this paragraph (i) shall become effective
at the open of business on (x) the ex-dividend date for such dividend or other distribution or (y) the date on which such split or combination becomes effective, as applicable. If any dividend or
distribution described in this paragraph (i) is declared but not so paid or made, the new conversion rate shall be readjusted to the conversion rate that would then be in effect if such dividend or distribution had not been declared.

 (ii) If the Company distributes to all holders of Common Stock any rights, warrants or options entitling them,
for a period expiring not more than 45 days after the date of issuance of such rights, warrants or options, to subscribe for or purchase shares of Common Stock at a price per share that is less than the Closing Sale Price per share of Common Stock
on the business day immediately preceding the time of announcement of such distribution, the Company shall adjust the conversion rate based on the following formula: 

CR1 = CR0 x (OS0+X)/(OS0+Y) 
 where

 CR0 = the conversion rate in effect immediately prior to the ex-dividend date for such
distribution; 
 CR1 = the new conversion rate in effect immediately on and after the ex-dividend date
for such distribution; 
 OS0 = the number of shares of Common Stock outstanding immediately prior to the
ex-dividend date for such distribution; 
 X = the aggregate number of shares of Common
Stock issuable pursuant to such rights, warrants or options; and 
 Y = the number of shares of Common Stock equal to the
quotient of (A) the aggregate price payable to exercise such rights, warrants or options 

  
 26 

 
and (B) the average of the Closing Sale Price per share of Common Stock for the 10 consecutive Trading Days ending on the business day immediately preceding the date of announcement for the
issuance of such rights, warrants or options. 
 For purposes of this paragraph (ii), in determining whether any rights,
warrants or options entitle the holders of shares of Common Stock to subscribe for or purchase shares of Common Stock at less than the applicable Closing Sale Price per share of Common Stock, and in determining the aggregate exercise or conversion
price payable for such shares of Common Stock, there shall be taken into account any consideration the Company receives for such rights, warrants or options and any amount payable on exercise or conversion thereof, with the value of such
consideration, if other than cash, to be determined by the Company’s board of directors. If any right, warrant or option described in this paragraph (ii) is not exercised or converted prior to the expiration of the exercisability or
convertibility thereof, the Company shall adjust the new conversion rate to the conversion rate that would then be in effect if such right, warrant or option had not been so issued. 

(iii) If the Company distributes shares of its capital stock, evidence of indebtedness or other assets or property to all
holders of Common Stock, excluding (A) dividends, distributions, rights, warrants or options referred to in paragraph (i) or (ii) above; (B) dividends or distributions paid exclusively in cash; and (C) spin-offs, as
described below in this paragraph (iii) then the Company shall adjust the conversion rate based on the following formula: 
 CR1 = CR0 x SP0/(SP0 – FMV) 

where 

CR0 = the conversion rate in effect immediately prior to the ex-dividend date for such
distribution; 
 CR1 = the new conversion rate in effect immediately on and after the ex-dividend date
for such distribution; 
 SP0 = the average of the Closing Sale Price per share of Common Stock for the 10 consecutive Trading Days ending on the
business day immediately preceding the ex-dividend date for such distribution; and 
 FMV
= the fair market value (as determined in good faith by the Company’s board of directors) of the shares of capital stock, evidences of indebtedness, assets or property distributed with respect to each outstanding share of Common Stock on the
earlier of the record date or the ex-dividend date for such distribution; 
 provided that if
“FMV” with respect to any distribution of shares of capital stock, evidences of indebtedness or other assets or property of the Company is equal to or greater than “SP0” with respect to such distribution, then in lieu of the
foregoing adjustment, adequate provision shall be 

  
 27 

 
made so that each holder of Series D Preferred Stock shall have the right to receive on the date such shares of capital stock, evidences of indebtedness or other assets or property of the Company
are distributed to holders of Common Stock, for each share of Series D Preferred Stock, the amount of shares of capital stock, evidences of indebtedness or other assets or property of the Company such holder of Series D Preferred Stock would have
received had such holder of Series D Preferred Stock owned a number of shares of Common Stock equal to a fraction the numerator of which is the product of the conversion rate in effect on the ex-dividend date
for such distribution, and the aggregate liquidation preference of Series D Preferred Stock held by such holder and the denominator of which is twenty-five ($25.00). 
 An adjustment to the conversion rate made pursuant to the immediately preceding paragraph shall become effective on the ex-dividend date for such distribution.

 If the Company distributes to all holders of Common Stock capital stock of any class or series, or similar equity interest,
of or relating to one of the Company’s subsidiaries or other business unit (a “spin-off”) the conversion rate in effect immediately before the 10th Trading Day from and including the effective date of the spin-off shall be adjusted based on the following formula: 
 CR1 = CR0 x (FMV0+MP0 )/ MP0 
 where

 CR0 = the conversion rate in effect immediately prior to the 10th Trading Day immediately following, and including, the
effective date of the spin-off; 
 CR1 = the new conversion rate in effect immediately on and after the 10th Trading Day immediately following, and including,
the effective date of the spin-off; 
 FMV0 = the average of the Closing Sale Prices per share of the capital stock or similar equity interest distributed to holders
of Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading Days after the effective date of the spin-off; and 
 MP0 = the
average of the Closing Sale Prices per share of Common Stock over the first 10 consecutive Trading Days after the effective date of the spin-off. 
 An adjustment to the conversion rate made pursuant to the immediately preceding paragraph shall occur on the 10th Trading Day from and including the effective date of the spin-off; provided that in
respect of any conversion within the 10 Trading Days following the effective date of any spin-off, references within this paragraph (iii) to 10 Trading Days shall be 

  
 28 

 
deemed replaced with such lesser number of Trading Days as have elapsed between the effective date of such spin-off and the Conversion Date in determining
the applicable conversion rate. 
 If any such dividend or distribution described in this paragraph (iii) is declared but
not paid or made, the new conversion rate shall be re-adjusted to be the conversion rate that would then be in effect if such dividend or distribution had not been declared. 

(iv) If the Company makes any cash dividend or distribution to all holders of outstanding shares of Common Stock
(excluding any dividend or distribution in connection with the Company’s liquidation, dissolution or winding up) during any of its quarterly fiscal periods in an aggregate amount that, together with other cash dividends or distributions made
during such quarterly fiscal period, exceeds the product of $0.31 (subject to adjustment) (the “reference dividend”), multiplied by the number of shares of Common Stock outstanding on the record date for such distribution, the conversion
rate shall be adjusted based on the following formula: 
 CR1 = CR0 x SP0/(SP0 – C) 

where 

CR0 = the conversion rate in effect immediately prior to the ex-dividend date for such
distribution; 
 CR1 = the new conversion rate in effect immediately after the ex-dividend date for
such distribution; 
 SP0 = the average of the Closing Sale Price per share of Common Stock for the 10 consecutive Trading Days ending on the
business day immediately preceding the earlier of the record date or the day prior to the ex-dividend date for such distribution; and 
 C = the amount in cash per share that the Company distributes to holders of Common Stock that exceeds the reference dividend; 
 provided that if “C” with respect to any such cash dividend or distribution is equal to or greater than “SP0” with respect to any such cash dividend or distribution, then in lieu of
the foregoing adjustment, adequate provision shall be made so that each holder of Series D Preferred Stock shall have the right to receive on the date such cash is distributed to holders of Common Stock, for each share of Series D Preferred Stock,
the amount of cash such holder of Series D Preferred Stock would have received had such holder of Series D Preferred Stock owned a number of shares of Common Stock equal to a fraction the numerator of which is the product of the conversion rate in
effect on the ex-dividend date for such dividend or distribution, and the aggregate principal amount of Series D Preferred Stock held by such holder and the denominator of which is twenty-five ($25.00).

  
 29 

 An adjustment to the conversion rate made pursuant to this paragraph (iv) shall become
effective on the ex-dividend date for such dividend or distribution. If any dividend or distribution described in this paragraph (iv) is declared but not so paid or made, the new conversion rate shall be re-adjusted to the conversion rate that would then be in effect if such dividend or distribution had not been declared. 
 The reference dividend amount is subject to adjustment in a manner inversely proportional to adjustments to the conversion rate; provided that no adjustment shall be made to the reference dividend amount
for any adjustment made to the conversion rate under this paragraph (iv). 
 Notwithstanding the foregoing, if an adjustment is
required to be made under this paragraph (iv) as a result of a distribution that is not a quarterly dividend, the reference dividend amount shall be deemed to be zero. 

(v) If the Company or any of its subsidiaries makes a payment in respect of a tender offer or exchange offer for shares of
Common Stock to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Closing Sale Price per share of Common Stock on the Trading Day next succeeding the last date on which
tenders or exchanges may be made pursuant to such tender offer or exchange offer, the conversion rate shall be adjusted based on the following formula: 
 CR1 = CR0 × (AC +
(SP1 × OS1))/(SP1 × OS0) 
 where

 CR0 = the conversion rate in effect on the day immediately following the date such tender or exchange offer expires;

 CR1 = the conversion rate in effect on the second day immediately following the date such tender or exchange offer expires;

 AC = the aggregate value of all cash and any other consideration (as determined by the Company’s board of directors) paid
or payable for shares of Common Stock purchased in such tender or exchange offer; 
 OS0 = the number of shares of Common Stock outstanding immediately prior to
the date such tender or exchange offer expires; 

OS1 = the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after
giving effect to the purchase or exchange of shares pursuant to such tender or exchange offer); and 

  
 30 

 SP1 = the Closing Sale Price per share of Common Stock for the Trading Day immediately following the date such tender or
exchange offer expires. 
 If 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 to the conversion rate made pursuant to this paragraph
(v) shall become effective on the second day immediately following the date such tender offer or exchange offer expires. If the Company or one of its subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender or
exchange offer but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the Company shall re-adjust the new conversion rate to be the conversion rate
that would be in effect if such tender or exchange offer had not been made. 
 (vi) If the Company has in effect
a rights plan while any shares of Series D Preferred Stock remain outstanding, holders of shares of Series D Preferred Stock shall receive, upon a conversion of such shares in respect of which the Company has elected to deliver shares of Common
Stock, in addition to such shares of Common Stock, rights under the Company’s stockholder rights agreement unless, prior to conversion, the rights have expired, terminated or been redeemed or unless the rights have separated from Common Stock.
If the rights provided for in any rights plan that the Company’s board of directors may adopt have separated from the Common Stock in accordance with the provisions of the applicable stockholder rights agreement so that holders of shares of
Series D Preferred Stock would not be entitled to receive any rights in respect of Common Stock that the Company elects to deliver upon conversion of shares of Series D Preferred Stock, the Company shall adjust the conversion rate at the time of
separation as if the Company had distributed to all holders of the Company’s capital stock, evidences of indebtedness or other assets or property pursuant to paragraph (iii) above, subject to readjustment upon the subsequent expiration,
termination or redemption of the rights. 
 (vii) Notwithstanding the foregoing, in the event of an adjustment to
the conversion rate pursuant to paragraphs (iv) and (v) above, in no event shall the conversion rate exceed 0.6997 shares of Common Stock per $25.00 liquidation preference, subject to adjustment pursuant to paragraphs (i), (ii) and
(iii) above. In no event shall the Conversion Price be reduced below $0.01, subject to adjustment for share splits and combinations and similar events. 
 (viii) The Company shall not make any adjustment to the conversion rate if holders of shares of Series D Preferred Stock are permitted to participate, on an
as-converted basis, in the transactions described in paragraphs (i) through (vi) above. 
 (ix) The conversion rate shall not be adjusted except as specifically set forth in this Section 8 to these Articles Supplementary. Without limiting the foregoing, the conversion rate shall not be
adjusted for (A) the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities or those of the Operating Partnership and the
investment of additional optional amounts in shares of Common Stock under any plan; (B) the issuance of any shares of Common Stock or options or rights to purchase 

  
 31 

 
such shares pursuant to any of the Company’s present or future employee, director, trustee or consultant benefit plan, employee agreement or arrangement or program or those of the Operating
Partnership; (C) the issuance of any shares of Common Stock pursuant to any option, warrant, right, or exercisable, exchangeable or convertible security outstanding as of the date shares of Series D Preferred Stock were first issued; (D) a
change in the par value of Common Stock; (E) accumulated and unpaid dividends or distributions; and (F) the issuance of limited partnership units by the Operating Partnership and the issuance of shares of Common Stock or the payment of
cash upon redemption thereof. 
 (x) No adjustment in the conversion rate shall be required unless the adjustment
would require an increase or decrease of at least 1% of the conversion rate. If the adjustment is not made because the adjustment does not change the conversion rate by at least 1%, then the adjustment that is not made shall be carried forward and
taken into account in any future adjustment. All required calculations shall be made to the nearest cent or 1/1000th of a share, as the case may be. Notwithstanding the foregoing, if the shares of Series D Preferred Stock are called for redemption,
all adjustments not previously made shall be made on the applicable redemption date. 
 (xi) Except as described
in this Section 8 of these Articles Supplementary, the Company shall not adjust the conversion rate for any issuance of shares of Common Stock or any securities convertible into or exchangeable or exercisable for shares of Common Stock or
rights to purchase shares of Common Stock or such convertible, exchangeable or exercisable securities. 
 (i) Effect of
Business Combinations. In the case of the following events (each a “business combination”): 
 (i)
any recapitalization, reclassification or change of Common Stock (other than changes resulting from a subdivision or combination); 
 (ii) a consolidation, merger or combination involving the Company; 

(iii) a sale, conveyance or lease to another corporation of all or substantially all of the Company’s property and
assets (other than to one or more of the Company’s subsidiaries); or 
 (iv) a statutory share exchange,

 in each case, as a result of which holders of Common Stock 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 Stock, a holder of shares of Series D Preferred Stock shall be entitled thereafter to convert such shares of Series D Preferred Stock into the kind and amount of
stock, other securities or other property or assets (including cash or any combination thereof) which the holder of shares of Series D Preferred Stock would have owned or been entitled to receive upon such business combination as if such holder of
shares of Series D Preferred Stock held a number of shares of Common Stock equal to the conversion rate in effect on the effective date for such business combination, multiplied by the number of shares of Series D Preferred Stock held by

  
 32 

 
such holder of shares of Series D Preferred Stock. If such business combination also constitutes a Fundamental Change, a holder of shares of Series D Preferred Stock converting such shares shall
not receive a make-whole premium pursuant to Section 8(k) hereof if such holder does not convert its shares of Series D Preferred Stock “in connection with” (as described in Section 8(k)(i)) the relevant Fundamental Change. In
the event that holders of Common Stock have the opportunity to elect the form of consideration to be received in such business combination, the Company shall make adequate provision whereby the holders of shares of Series D Preferred Stock shall
have a reasonable opportunity to determine the form of consideration into which all of the shares of Series D Preferred Stock, 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 shares of Series D Preferred Stock who participate in such determination, shall be subject to any limitations to which all holders of Common Stock 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 (1) the deadline for elections to
be made by holders of Common Stock and (2) two business days prior to the anticipated effective date of the business combination. 
 The Company 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 shares of Series D Preferred Stock (and the
weighted average of elections), by posting such notice with DTC and providing a copy of such notice to the Company’s transfer agent. If the effective date of a business combination is delayed beyond the initially anticipated effective date, the
holders of shares of Series D Preferred Stock shall be given the opportunity to make subsequent similar determinations in regard to such delayed effective date. The Company may not become a party to any such transaction unless its terms are
consistent with the preceding. None of the foregoing provisions shall affect the right of a holder of shares of Series D Preferred Stock to convert such holder’s shares of Series D Preferred Stock into shares of Common Stock prior to the
effective date of such business combination. 
 (j) Optional Increase to Conversion Rate. To the extent permitted by law,
the Company may, from time to time, increase the conversion rate for a period of at least 20 days if the Company’s board of directors determines that such an increase would be in the Company’s best interests. Any such determination by the
Company’s board of directors shall be conclusive. In addition, the Company may increase the conversion rate if the Company’s board of directors deems it advisable to avoid or diminish any income tax to holders of Common Stock resulting
from any distribution of Common Stock or similar event. The Company shall give holders of shares of Series D Preferred Stock at least 15 business days’ notice of any increase in the conversion rate. 

(k) Adjustment to Conversion Rate upon Certain Fundamental Changes. The Company shall adjust the conversion rate from time to time
as follows: 
 (i) If, on or prior to February 6, 2015, a Fundamental Change takes place and a holder
converts the Series D Preferred Stock in connection with such Fundamental Change, the Company shall increase, as described below, the conversion rate applicable to shares that are surrendered for conversion. A conversion of the Series D Preferred

  
 33 

 
Stock shall be deemed for these purposes to be “in connection with” a Fundamental Change if the Conversion Date occurs from and including the effective date of such Fundamental Change
to, and including, the Fundamental Change Conversion Date (as defined in Section 8(l)(vii)) for that Fundamental Change. 
 (ii) The Company shall also give notice by mail or by publication (with subsequent prompt notice by mail) to holders of Series D Preferred Stock of the anticipated effective date of any proposed
Fundamental Change which shall occur on or prior to February 6, 2015. The Company shall make this mailing or publication at least 15 days before the anticipated effective date of the Fundamental Change. In addition, no later than the third
business day after the completion of such Fundamental Change, the Company shall make an additional notice announcing such completion. 
 (iii) If a holder elects to convert in connection with a Fundamental Change on or prior to February 6, 2015, the Company shall increase the Conversion Rate by reference to the table below, based on
the date when the Fundamental Change becomes effective (the “effective date”), and the applicable price. If the Fundamental Change is a transaction or series of related transactions and the consideration (excluding cash payments for
fractional shares or pursuant to statutory appraisal rights) for Common Stock in the Fundamental Change consists solely of cash, then the applicable price shall be the cash amount paid per share of Common Stock in the transaction. If the transaction
is an asset sale and the consideration paid for the Company’s property and assets (or for the property and assets of the Company and its subsidiaries on a consolidated basis) consists solely of cash, then the applicable price shall be the cash
amount paid for the Company’s property and assets, expressed as an amount per share of Common Stock outstanding on the effective date of the asset sale. In all other cases, the applicable price shall be the average of the Closing Sale Price per
share of Common Stock for the ten consecutive Trading Days immediately preceding the effective date. The Company’s board of directors shall make appropriate adjustments, in its good faith determination, to account for any adjustment to the
conversion rate that becomes effective, or any event requiring an adjustment to the conversion rate where the ex-dividend date of the event occurs, at any time during those ten consecutive Trading Days.

 (iv) The following table sets forth the number of additional shares of Common Stock per $25.00 liquidation
preference of Series D Preferred Stock that shall be added to the Conversion Rate applicable to Series D Preferred Stock that are converted in connection with a Fundamental Change (the “make-whole premium”). If an event occurs that
requires an adjustment to the Conversion Rate, the Company shall, on the date the Company must adjust the Conversion Rate, adjust each applicable price set forth in the column headers of the table below by multiplying the applicable price in effect
immediately before the adjustment by a fraction (A) whose numerator is the Conversion Rate in effect immediately before the adjustment; and (B) whose denominator is the adjusted Conversion Rate. 

In addition, the Company shall adjust the number of additional shares in the table below in the same manner in which, and for the same
events for which, the Company must adjust the Conversion Rate as described in Section 8(h).

 (v) The exact applicable share price and effective date may not be set forth in the table
above, in which case (A) if the actual applicable share price is between two applicable prices listed in the table above, or the actual effective date is between two dates listed in the table above, the Company 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; (B) if the actual
applicable price is greater than $90.00 per share (subject to adjustment), the Company shall not increase the Conversion Rate as described above and no additional shares shall be issuable upon conversion; and (C) if the actual applicable price
is less than $35.73 per share (subject to adjustment), the Company shall not increase the Conversion Rate as described above and no additional shares shall be issuable upon conversion. 

(vi) The Company shall not increase the Conversion Rate as described in this Section 8(k) of these Articles
Supplementary to the extent the increase will cause the Conversion Rate to exceed 0.6997, provided the Company shall adjust this maximum conversion rate in the same manner in which, and for the same events for which, the Company must adjust the
Conversion Rate as described in Section 8(h). 
 (l) Special Conversion Right of Series D Preferred Stock upon a
Fundamental Change; Company Repurchase Right. 
 (i) On or prior to February 6, 2015, in the event of a
Fundamental Change, when the applicable price of Common Stock described in Section 8(k)(iii) of these Articles Supplementary is less than $35.73 per share, then each holder of Series D Preferred Stock shall have the special right (the
“Fundamental Change Conversion Right”), in addition to any other applicable conversion right, to convert some or all of the Series D Preferred Stock on the relevant Fundamental Change Conversion Date into a number of shares of
Common Stock per $25.00 liquidation preference equal to such liquidation preference plus an amount equal to accrued and unpaid dividends to, but not including, such Fundamental Change Conversion Date, divided by 98% of the Market Price of Common
Stock (the “Fundamental Change Conversion Rate”). The Market Price of Common Stock shall be determined prior to the applicable Fundamental Change Conversion Date. A holder of Series D Preferred Stock which has elected to convert
such shares otherwise than pursuant to the Fundamental Change Conversion Right shall not be able to exercise the Fundamental Change Conversion Right. 

  
 35 

 (ii) If a holder of Series D Preferred Stock elects to convert Series D
Preferred Stock as described in Section 8(l)(i) of these Articles Supplementary, the Company may elect, in lieu of that conversion, to repurchase for cash some or all of such Series D Preferred Stock at a repurchase price (the
“Fundamental Change Repurchase Price”) equal to 100% of the liquidation preference of the Series D Preferred Stock to be repurchased plus an amount equal to accrued and unpaid dividends to, but not including, such Fundamental Change
Conversion Date, or 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 Company
shall pay such dividends to the holder of record on the corresponding Dividend Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the liquidation preference of the Series D Preferred Stock to be repurchased.

 (iii) If the Company elects to repurchase Series D Preferred Stock that would otherwise be converted into
Common Stock on a Fundamental Change Conversion Date, such Series D Preferred Stock shall not be converted into Common Stock and the holder of such shares shall be entitled to receive the Fundamental Change Repurchase Price in cash from the Company.

 (iv) The aggregate number of shares of Common Stock issuable in connection with the exercise of the
Fundamental Change Conversion Right may not exceed 14.3 million shares of Common Stock (or 16.4 million shares of Common Stock if the underwriter of the Company’s offering of the Series D Preferred Stock exercises its over-allotment
option in full) or such other number of shares of Common Stock as shall then be authorized and available for issuance. If the number of shares of Common Stock issuable upon such conversion would exceed 14.3 million or 16.4 million shares
of Common Stock, as the case may be, or such other number of shares of Common Stock as shall then be authorized and available for issuance, the Company shall have the option to satisfy the remainder of such conversion in shares of Common Stock that
are authorized for issuance in the future. The Company shall use its best efforts to have any such additional number of shares of Common Stock authorized for issuance within 180 days of the Fundamental Change Conversion Date. 

(v) (v) Within 15 days after the occurrence of a Fundamental Change, the Company shall provide to the holder of Series D
Preferred Stock and the Company’s transfer agent a notice of the occurrence of the Fundamental Change and of the resulting repurchase right. Such notice shall state (A) the events constituting the Fundamental Change; (B) the date of
the Fundamental Change; (C) the last date on which the holder of Series D Preferred Stock may exercise the Fundamental Change Conversion Right; (D) to the extent applicable, the Fundamental Change Conversion Rate and the Fundamental Change
Repurchase Price; (E) that the Company may elect to repurchase some or all of the Series D Preferred Stock as to which the Fundamental Change Conversion Right may be exercised; (F) the method of calculating the Market Price of Common
Stock; (G) the Fundamental Change Conversion Date; (H) the name and address of the paying agent and the conversion agent; (I) the Conversion Rate and any adjustment to the Conversion Rate that shall result from the Fundamental Change;
(J) that Series D Preferred Stock as to 

  
 36 

 
which the Fundamental Change Conversion Right has been exercised may be converted at the applicable Conversion Rate, if otherwise convertible, only if the notice of exercise of the Fundamental
Change Conversion Right has been properly withdrawn; and (K) the procedures that the holder of Series D Preferred Stock must follow to exercise the Fundamental Change Conversion Right. 

(vi) The Company shall also issue a press release for publication on 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), or post notice on the Company’s website, in any event prior to the opening of business on the first Trading Day following any date on which the Company provides such notice to the holders of Series D Preferred Stock. 

(vii) The Fundamental Change Conversion Date shall be a date no less than 20 days nor more than 35 days after the date on
which the Company gives the notice described in Section 8(l)(v) of these Articles Supplementary. To exercise the Fundamental Change Conversion Right, the holder of Series D Preferred Stock shall deliver, on or before the close of business on
the Fundamental Change Conversion Date, the Series D Preferred Stock to be converted, duly endorsed for transfer, together with a written conversion notice completed, to the Company’s transfer agent. The conversion notice shall state
(A) the relevant Fundamental Change Conversion Date; (B) the number of Series D Preferred Stock to be converted; and (C) that the Series D Preferred Stock are to be converted pursuant to the applicable provisions of the Series D
Preferred Stock. Notwithstanding the foregoing, if the Series D Preferred Stock is held in global form, the conversion notice shall comply with applicable DTC procedures. 

(viii) Holders of Series D Preferred Stock may withdraw any notice of exercise of its Fundamental Change Conversion Right
(in whole or in part) by a written notice of withdrawal delivered to the Company’s transfer agent prior to the close of business on the business day prior to the Fundamental Change Conversion Date. The notice of withdrawal shall state
(A) the number of withdrawn shares of Series D Preferred Stock; (B) if certificated shares of Series D Preferred Stock have been issued, the certificate numbers of the withdrawn shares of Series D Preferred Stock; and (C) the number
of shares of the Series D Preferred Stock, if any, which remain subject to the conversion notice. Notwithstanding the foregoing, if the Series D Preferred Stock is held in global form, the notice of withdrawal shall comply with applicable DTC
procedures. 
 (ix) Series D Preferred Stock as to which the Fundamental Change Conversion Right has been
properly exercised and for which the conversion notice has not been properly withdrawn shall be converted into shares of Common Stock in accordance with the Fundamental Change Conversion Right on the Fundamental Change Conversion Date, unless the
Company has elected to repurchase such Series D Preferred Stock. 
 (x) The holder of any shares of Series D
Preferred Stock which the Company has elected to repurchase and as to which the conversion election has not been properly withdrawn shall receive payment of the Fundamental Change Repurchase Price promptly

following the later of the Fundamental Change Conversion Date or the time of book-entry transfer or delivery of the Series D Preferred Stock. If the paying agent holds cash sufficient to pay the
Fundamental Change Repurchase Price of the Series D Preferred Stock on the business day following the Fundamental Change Conversion Date, then (A) the Series D Preferred Stock shall cease to be outstanding and dividends shall cease to accrue
(whether or not book-entry transfer of the Series D Preferred Stock is made or whether or not the Series D Preferred Stock certificate is delivered to the Company’s transfer agent); and (B) all of the other rights of the holder of Series D
Preferred Stock shall terminate (other than the right to receive the Fundamental Change Repurchase Price upon delivery or transfer of the Series D Preferred Stock). 
 SECTION 9. Record Holders. The Company and its transfer agent may deem and treat the record holder of any Series D Preferred Stock as the true and lawful owner thereof for all purposes, and neither
the Company nor its transfer agent shall be affected by any notice to the contrary. 
 SECTION 10. No Maturity or Sinking
Fund. The Series D Preferred Stock has no maturity date, and no sinking fund has been established for the retirement or redemption of Series D Preferred Stock; provided, however, that the Series D Preferred Stock owned by a stockholder in excess
of the Ownership Limit shall be subject to the provisions of Section 5 and Section 7 of these Articles Supplementary. 

SECTION 11. Exclusion of Other Rights. The Series D Preferred Stock shall not have any preferences or other rights, voting powers,
restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption other than expressly set forth in the Charter and these Articles Supplementary. 

SECTION 12. Headings of Subdivisions. The headings of the various subdivisions hereof are for convenience of reference only and
shall not affect the interpretation of any of the provisions hereof. 
 SECTION 13. Severability of Provisions. If any
preferences or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption of the Series D Preferred Stock set forth in the Charter and these Articles
Supplementary are invalid, unlawful or incapable of being enforced by reason of any rule of law or public policy, all other preferences or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications
or terms or conditions of redemption of Series D Preferred Stock set forth in the Charter which can be given effect without the invalid, unlawful or unenforceable provision thereof shall, nevertheless, remain in full force and effect and no
preferences or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption of the Series D Preferred Stock herein set forth shall be deemed dependent upon any
other provision thereof unless so expressed therein. 

  
 38 

 SECTION 14. No Preemptive Rights. No holder of Series D Preferred Stock shall be
entitled to any preemptive rights to subscribe for or acquire any unissued shares of capital stock of the Company (whether now or hereafter authorized) or securities of the Company convertible into or carrying a right to subscribe to or acquire

ARTICLES SUPPLEMENTARY 
 11,500,000 SHARES OF 
 7.000% SERIES E CUMULATIVE REDEEMABLE PREFERRED
STOCK 
 SEPTEMBER 14, 2011 

Digital Realty Trust, Inc., a Maryland corporation (the “Company”), hereby certifies to the State Department of
Assessments and Taxation of Maryland (the “Department”) that: 
 FIRST: Pursuant to the authority
expressly vested in the Board of Directors of the Company (the “Board of Directors”) by Article IV of the Articles of Amendment and Restatement of the Company filed with the Department on October 26, 2004 (the
“Charter”) and Section 2-105 of the Maryland General Corporation Law (the “MGCL”), the Board of Directors, by resolutions duly adopted on January 4, 2011 and
July 25, 2011, has authorized the issuance, classification and designation of a number of shares of the authorized but unissued preferred stock of the Company, par value $0.01 per share (“Preferred Stock”), as a separate class
of Preferred Stock, that, on the date of issue, have a liquidation value of up to $250,000,000 (plus up to an additional 15% to cover any underwriter over-allotment option), and, pursuant to the powers contained in the Bylaws of the Company and the
MGCL, appointed a committee (the “Committee”) of the Board of Directors and delegated to the Committee, to the fullest extent permitted by the MGCL and the Charter and Bylaws of the Company, among other things, all powers of the
Board of Directors with respect to (i) setting the number of shares of the Preferred Stock to be classified and designated, provided that in no event shall the liquidation value of such shares exceed $250,000,000 (plus up to an additional 15%
to cover any underwriter over-allotment option), (ii) choosing the cumulative dividend percentage for the Preferred Stock, (iii) selecting the dates on which dividends will be paid on the Preferred Stock, (iv) establishing the price
per share for the Preferred Stock, (v) authorizing, approving and filing these Articles Supplementary with the Department and (vi) authorizing and approving all such other actions as the Committee may deem necessary or desirable in
connection with the classification, authorization, issuance, offer, and sale of the Preferred Stock. 
 SECOND: The
Committee has unanimously adopted resolutions classifying and designating the Preferred Stock as a separate class of Preferred Stock to be known as the “7.000% Series E Cumulative Redeemable Preferred Stock,” setting the preferences,
conversion and other rights, voting powers, restrictions, limitations as to dividends and other distributions, transfers, qualifications, terms and conditions of redemption and other terms and conditions of such 7.000% Series E Cumulative Redeemable
Preferred Stock, and authorizing the issuance of up to 10,000,000 (plus up to an additional 15% to cover any underwriter over-allotment option) shares of 7.000% Series E Cumulative Redeemable Preferred Stock. 

THIRD: The designation, number of shares, preferences, rights, voting powers, restrictions, limitations as to dividends and other
distributions, qualifications, terms and conditions of redemption and other terms and conditions of the separate class of Preferred Stock of the Company designated as the 7.000% Series E Cumulative Redeemable Preferred Stock are as follows, which
upon any restatement of the Charter shall be made a part of or incorporated by reference into the Charter with any necessary or appropriate changes to the enumeration or lettering of Sections or subsections thereof: 

Section 1. Designation and Number. A series of Preferred Stock, designated the “7.000% Series E Cumulative Redeemable
Preferred Stock” (the “Series E Preferred Stock”), is hereby established. The number of shares of Series E Preferred Stock shall be 11,500,000. 
 Section 2. Rank. The Series E Preferred Stock will, with respect to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company, rank:
(a) senior to all classes or series of the Company’s common stock, par value $0.01 per share (the “Common Stock”), and all classes or series of capital stock of the Company now or hereafter authorized, issued or
outstanding expressly designated as ranking junior to the Series E Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation, 

 
dissolution or winding up of the Company; (b) on parity with the Series C Cumulative Convertible Preferred Stock, par value $0.01 per share, and the Series D Cumulative Convertible Preferred
Stock, par value $0.01 per share, of the Company and with any class or series of capital stock of the Company expressly designated as ranking on parity with the Series E Preferred Stock as to dividend rights and rights upon voluntary or involuntary
liquidation, dissolution or winding up of the Company; and (c) junior to any class or series of capital stock of the Company expressly designated as ranking senior to the Series E Preferred Stock as to dividend rights and rights upon voluntary
or involuntary liquidation, dissolution or winding up of the Company. The term “capital stock” does not include convertible or exchangeable debt securities, which will rank senior to the Series E Preferred Stock prior to conversion
or exchange. The Series E Preferred Stock will also rank junior in right of payment to the Company’s other existing and future debt obligations. 
 Section 3. Dividends. 
 (a) Subject to the preferential rights of the
holders of any class or series of capital stock of the Company ranking senior to the Series E Preferred Stock as to dividends, the holders of shares of the Series E Preferred Stock shall be entitled to receive, when, as and if authorized by the
Board of Directors and declared by the Company, out of funds legally available for the payment of dividends, cumulative cash dividends at the rate of 7.000% per annum of the $25.00 liquidation preference per share of the Series E Preferred
Stock (equivalent to a fixed annual amount of $1.75 per share of the Series E Preferred Stock). Such dividends shall accrue and be cumulative from and including the first date on which any shares of Series E Preferred Stock are issued (the
“Original Issue Date”) and shall be payable quarterly in arrears on each Dividend Payment Date (as defined below), commencing December 30, 2011; provided, however, that if any Dividend Payment Date is not a
Business Day (as defined below), then the dividend which would otherwise have been payable on such Dividend Payment Date may be paid on the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case 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. The amount of any dividend payable on the Series E Preferred Stock for any partial Dividend Period (as defined below) shall be prorated and computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends will be payable to holders of record as they appear in the stockholder records of the Company at the close of
business on the applicable Dividend Record Date (as defined below). Notwithstanding any provision to the contrary contained herein, each outstanding share of Series E Preferred Stock shall be entitled to receive a dividend with respect to any
Dividend Record Date equal to the dividend paid with respect to each other share of Series E Preferred Stock that is outstanding on such date. “Dividend Record Date” shall mean the date designated by the Board of Directors for the
payment of dividends that is not more than 35 or fewer than 10 days prior to the applicable Dividend Payment Date. “Dividend Payment Date” shall mean the last calendar day of each March, June, September and December, commencing on
December 30, 2011. “Dividend Period” shall mean the respective periods commencing on and including the first day of January, April, July and October of each year and ending on and including the day preceding the first day of
the next succeeding Dividend Period (other than the initial Dividend Period, which shall commence on the Original Issue Date and end on and include December 31, 2011, and other than the Dividend Period during which any shares of Series E
Preferred Stock shall be redeemed pursuant to Section 5 or Section 6, which shall end on and include the day preceding the call date with respect to the shares of Series E Preferred Stock being redeemed). 

The term “Business Day” shall mean each day, other than a Saturday or a Sunday, which is not a day on which banking
institutions in New York, New York are authorized or required by law, regulation or executive order to close. 
 (b)
Notwithstanding anything contained herein to the contrary, dividends on the Series E Preferred Stock shall accrue whether or not the Company has earnings, whether or not there are funds legally available for the payment of such dividends, and
whether or not such dividends are authorized or declared. 
 (c) Except as provided in Section 3(d) below, no dividends
shall be declared and paid or declared and set apart for payment, and no other distribution of cash or other property may be declared and made, directly or indirectly, on or with respect to, any shares of Common Stock or shares of any other class or
series of capital stock of the Company ranking, as to dividends, on parity with or junior to the Series E Preferred Stock (other than a 

  
 2 

 
dividend paid in shares of Common Stock or in shares of any other class or series of capital stock ranking junior to the Series E Preferred Stock as to dividends and upon liquidation) for any
period, nor shall any shares of Common Stock or any other shares of any other class or series of capital stock of the Company ranking, as to dividends or upon liquidation, on parity with or junior to the Series E Preferred Stock be redeemed,
purchased or otherwise acquired for any consideration, nor shall any funds be paid or made available for a sinking fund for the redemption of such shares, and no other distribution of cash or other property may be made, directly or indirectly, on or
with respect thereto by the Company (except by conversion into or exchange for other shares of any class or series of capital stock of the Company ranking junior to the Series E Preferred Stock as to dividends and upon liquidation, and except for
the acquisition of shares made pursuant to the provisions of Article VI of the Charter or Section 9 hereof), unless full cumulative dividends on the Series E Preferred Stock for all past dividend periods shall have been or contemporaneously are
(i) declared and paid in cash or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for such payment. 
 (d) When dividends are not paid in full (and a sum sufficient for such full payment is not so set apart) on the Series E Preferred Stock and the shares of any other class or series of capital stock
ranking, as to dividends, on parity with the Series E Preferred Stock, all dividends declared upon the Series E Preferred Stock and each such other class or series of capital stock ranking, as to dividends, on parity with the Series E Preferred
Stock shall be declared pro rata so that the amount of dividends declared per share of Series E Preferred Stock and such other class or series of capital stock shall in all cases bear to each other the same ratio that accrued dividends per share on
the Series E Preferred Stock and such other class or series of capital stock (which shall not include any accrual in respect of unpaid dividends on such other class or series of capital stock for prior dividend periods if such other class or series
of capital stock does not have a cumulative dividend) bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or payments on the Series E Preferred Stock which may be in arrears.

 (e) Holders of shares of Series E Preferred Stock shall not be entitled to any dividend, whether payable in cash, property or
shares of stock, in excess of full cumulative dividends on the Series E Preferred Stock as provided herein. Any dividend payment made on the Series E Preferred Stock shall first be credited against the earliest accrued but unpaid dividends due with
respect to such shares which remain payable. Accrued but unpaid distributions on the Series E Preferred Stock will accumulate as of the Dividend Payment Date on which they first become payable. 

Section 4. Liquidation Preference. 
 (a) Upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, before any distribution or payment shall be made to holders of shares of Common Stock or any other class or
series of capital stock of the Company ranking, as to rights upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, junior to the Series E Preferred Stock, the holders of shares of Series E Preferred Stock shall be
entitled to be paid out of the assets of the Company legally available for distribution to its stockholders, after payment of or provision for the debts and other liabilities of the Company, a liquidation preference of $25.00 per share, plus an
amount equal to any accrued and unpaid dividends (whether or not authorized or declared) to but excluding the date of payment. In the event that, upon such voluntary or involuntary liquidation, dissolution or winding up, the available assets of the
Company are insufficient to pay the full amount of the liquidating distributions on all outstanding shares of Series E Preferred Stock and the corresponding amounts payable on all shares of other classes or series of capital stock of the Company
ranking, as to liquidation rights, on parity with the Series E Preferred Stock in the distribution of assets, then the holders of the Series E Preferred Stock and each such other class or series of shares of capital stock ranking, as to voluntary or
involuntary liquidation rights, on parity with the Series E Preferred Stock shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled. Written
notice of any such voluntary or involuntary liquidation, dissolution or winding up of the Company, stating the payment date or dates when, and the place or places where, the amounts distributable in such circumstances shall be payable, shall be
given by first class mail, postage pre-paid, not fewer than 30 or more than 60 days prior to the payment date stated therein, to each record holder of shares of Series E Preferred Stock at the respective
addresses of such holders as the same shall appear on the stock transfer records of the Company. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of Series E Preferred Stock will have no right
or claim to any of the remaining assets of the Company. The consolidation or merger of the Company with or into any other 

  
 3 

 
corporation, trust or entity, or the voluntary sale, lease, transfer or conveyance of all or substantially all of the property or business of the Company, shall not be deemed to constitute a
liquidation, dissolution or winding up of the Company. 
 (b) In determining whether a distribution (other than upon voluntary
or involuntary liquidation), by dividend, redemption or other acquisition of shares of capital stock of the Company or otherwise, is permitted under the MGCL, amounts that would be needed, if the Company were to be dissolved at the time of the
distribution, to satisfy the preferential rights upon dissolution of holders of shares of Series E Preferred Stock shall not be added to the Company’s total liabilities. 
 Section 5. Redemption. 
 (a) Shares of Series E Preferred Stock shall not
be redeemable prior to September 15, 2016 except as set forth in Section 6 or to preserve the status of the Company as a REIT (as defined in Section 9(a)) for United States federal income tax purposes. In addition, the Series E
Preferred Stock shall be subject to the provisions of Section 9 pursuant to which Series E Preferred Stock owned by a stockholder in excess of the Ownership Limit (as defined in Section 9(a)) shall automatically be transferred to a Trust
(as defined in Section 9(a)) for the exclusive benefit of a Charitable Beneficiary (as defined in Section 9(a)). 

(b) On and after September 15, 2016, the Company, at its option upon not fewer than 30 or more than 60 days’ written notice,
may redeem the Series E Preferred Stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends (whether or not declared) thereon up to but not including the
date fixed for redemption, without interest, to the extent the Company has funds legally available therefor (the “Redemption Right”). If fewer than all of the outstanding shares of Series E Preferred Stock are to be redeemed, the
shares of Series E Preferred Stock to be redeemed shall be redeemed pro rata (as nearly as may be practicable without creating fractional shares) by lot or by any other equitable method determined by the Company that will not result in a violation
of the Ownership Limit or the Aggregate Stock Ownership Limit (each as defined in Section 9(a)). If redemption is to be by lot and, as a result, any holder of shares of Series E Preferred Stock would have actual ownership, Beneficial Ownership
or Constructive Ownership (each as defined in Section 9(a)) in excess of the Ownership Limit (as defined in Section 9(a)), the Aggregate Stock Ownership Limit (as defined in Section 9(a)), or such other limit as permitted by the Board
of Directors or the Committee pursuant to Section 9(i), because such holder’s shares of Series E Preferred Stock were not redeemed, or were only redeemed in part, then, except as otherwise provided in the Charter, the Company shall redeem
the requisite number of shares of Series E Preferred Stock of such holder such that no holder will hold an amount of Series E Preferred Stock in excess of the applicable ownership limit, subsequent to such redemption. Holders of Series E Preferred
Stock to be redeemed shall surrender such Series E Preferred Stock at the place designated in such notice and shall be entitled to the redemption price of $25.00 per share and any accrued and unpaid dividends payable upon such redemption following
such surrender. If (i) notice of redemption of any shares of Series E Preferred Stock has been given, (ii) the funds necessary for such redemption have been set aside by the Company in trust for the benefit of the holders of any shares of
Series E Preferred Stock so called for redemption, and (iii) irrevocable instructions have been given to pay the redemption price and all accrued and unpaid dividends, then from and after the redemption date, dividends shall cease to accrue on
such shares of Series E Preferred Stock, such shares of Series E Preferred Stock shall no longer be deemed outstanding, and all rights of the holders of such shares shall terminate, except the right to receive the redemption price plus any accrued
and unpaid dividends payable upon such redemption, without interest. So long as full cumulative dividends on the Series E Preferred Stock for all past dividend periods shall have been or contemporaneously are (i) declared and paid in cash, or
(ii) declared and a sum sufficient for the payment thereof in cash is set apart for payment, nothing herein shall prevent or restrict the Company’s right or ability to purchase, from time to time, either at a public or a private sale, all
or any part of the Series E Preferred Stock at such price or prices as the Company may determine, subject to the provisions of applicable law, including the repurchase of shares of Series E Preferred Stock in open-market transactions duly authorized
by the Board of Directors. 
 (c) In the event of any redemption of the Series E Preferred Stock in order to preserve the status
of the Company as a REIT for United States federal income tax purposes, such redemption shall be made in accordance with the terms and conditions set forth in this Section 5 of these Articles Supplementary. If the Company calls for redemption
any shares of Series E Preferred Stock pursuant to and in accordance with this Section 5(c), then the 

  
 4 

 
redemption price for such shares will be an amount in cash equal to $25.00 per share together with all accrued and unpaid dividends to but excluding the dated fixed for redemption. 

(d) Unless full cumulative dividends on the Series E Preferred Stock for all past dividend periods shall have been or contemporaneously
are (i) declared and paid in cash, or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for payment, no shares of Series E Preferred Stock shall be redeemed pursuant to the Redemption Right or Special Optional
Redemption Right (defined below) unless all outstanding shares of Series E Preferred Stock are simultaneously redeemed, and the Company shall not purchase or otherwise acquire directly or indirectly any shares of Series E Preferred Stock or any
class or series of capital stock of the Company ranking, as to dividends or upon liquidation, on parity with or junior to the Series E Preferred Stock (except by conversion into or exchange for shares of capital stock of the Company ranking, as to
dividends and upon liquidation, junior to the Series E Preferred Stock); provided, however, that the foregoing shall not prevent the purchase of Series E Preferred Stock, or any other class or series of capital stock of the Company
ranking, as to dividends or upon liquidation, on parity with or junior to the Series E Preferred Stock, by the Company in accordance with the terms of Sections 5(c) and 9 of these Articles Supplementary or otherwise, in order to ensure that the
Company remains qualified as a REIT for United States federal income tax purposes, or the purchase or acquisition of Series E Preferred Stock pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding shares of
Series E Preferred Stock. 
 (e) Notice of redemption pursuant to the Redemption Right will be given by publication in a
newspaper of general circulation in the City of New York, such publication to be made once a week for two successive weeks commencing not fewer than 30 or more than 60 days prior to the redemption date. A similar notice will be mailed by the
Company, postage prepaid, not fewer than 30 or more than 60 days prior to the redemption date, addressed to the respective holders of record of the Series E Preferred Stock to be redeemed at their respective addresses as they appear on the transfer
records of the Company. No failure to give or defect in such notice shall affect the validity of the proceedings for the redemption of any Series E Preferred Stock except as to the holder to whom such notice was defective or not given. In addition
to any information required by law or by the applicable rules of any exchange upon which the Series E Preferred Stock may be listed or admitted to trading, each such notice shall state: (i) the redemption date; (ii) the redemption price;
(iii) the number of shares of Series E Preferred Stock to be redeemed; (iv) the place or places where the certificates, if any, representing shares of Series E Preferred Stock are to be surrendered for payment of the redemption price;
(v) procedures for surrendering noncertificated shares of Series E Preferred Stock for payment of the redemption price; (vi) that dividends on the shares of Series E Preferred Stock to be redeemed will cease to accumulate on such
redemption date; and (vii) that payment of the redemption price and any accumulated and unpaid dividends will be made upon presentation and surrender of such Series E Preferred Stock. If fewer than all of the shares of Series E Preferred Stock
held by any holder are to be redeemed, the notice mailed to such holder shall also specify the number of shares of Series E Preferred Stock held by such holder to be redeemed. Notwithstanding anything else to the contrary in these Articles
Supplementary, the Company shall not be required to provide notice to the holder of Series E Preferred Stock in the event such holder’s Series E Preferred Stock is redeemed in accordance with Sections 5(c) and 9 of these Articles Supplementary
to preserve the Company’s status as a REIT. 
 (f) If a redemption date falls after a Dividend Record Date and on or prior
to the corresponding Dividend Payment Date, each holder of Series E Preferred Stock at the close of business of such Dividend Record Date shall be entitled to the dividend payable on such shares on the corresponding Dividend Payment Date
notwithstanding the redemption of such shares on or prior to such Dividend Payment Date, and each holder of Series E Preferred Stock that surrenders its shares on such redemption date will be entitled to the dividends accruing after the end of the
Dividend Period to which such Dividend Payment Date relates up to but excluding the redemption date. Except as provided herein, the Company shall make no payment or allowance for unpaid dividends, whether or not in arrears, on Series E Preferred
Stock for which a notice of redemption has been given. 
 (g) All shares of the Series E Preferred Stock redeemed or repurchased
pursuant to this Section 5, or otherwise acquired in any other manner by the Company, shall be retired and shall be restored to the status of authorized but unissued shares of Preferred Stock, without designation as to series or class.

 (h) The Series E Preferred Stock shall have no stated maturity and shall not be subject to any sinking fund or mandatory
redemption; provided, however, that the Series E Preferred Stock owned by a stockholder in excess of 

  
 5 

 
the applicable ownership limit shall be subject to the provisions of this Section 5 and Section 9 of these Articles Supplementary. 

Section 6. Special Optional Redemption by the Company. 
 (a) Upon the occurrence of a Change of Control (as defined below), the Company will have the option upon written notice mailed by the Company, postage pre-paid, no
fewer than 30 nor more than 60 days prior to the redemption date and addressed to the holders of record of shares of the Series E Preferred Stock to be redeemed at their respective addresses as they appear on the share transfer records of the
Company, to redeem shares of the Series E Preferred Stock, in whole or in part within 120 days after the first date on which such Change of Control occurred, for cash at $25.00 per share plus accrued and unpaid dividends, if any, to, but not
including, the redemption date (“Special Optional Redemption Right”). No failure to give such notice or any defect thereto or in the mailing thereof shall affect the validity of the proceedings for the redemption of any shares of
Series E Preferred Stock except as to the holder to whom notice was defective or not given. If, prior to the Change of Control Conversion Date (as defined below), the Company has provided or provides notice of redemption with respect to the Series E
Preferred Stock (whether pursuant to the Redemption Right or the Special Optional Redemption Right), the holders of shares of Series E Preferred Stock will not have the conversion right described below in Section 8. 

A “Change of Control” is when, after the original issuance of the Series E Preferred Stock, the following have occurred
and are continuing: 
 (i) the acquisition by any person, including any syndicate or group deemed to be a “person”
under Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), of beneficial ownership, directly or indirectly, through a purchase, merger or other acquisition transaction or series of
purchases, mergers or other acquisition transactions of stock of the Company entitling that person to exercise more than 50% of the total voting power of all stock of the Company entitled to vote generally in the election of the Company’s
directors (except that such person will be deemed to have beneficial ownership of all securities that such person has the right to acquire, whether such right is currently exercisable or is exercisable only upon the occurrence of a subsequent
condition); and 
 (ii) following the closing of any transaction referred to in (i) above, neither the Company nor the
acquiring or surviving entity has a class of common securities (or American Depositary Receipts representing such securities) listed on the New York Stock Exchange (the “NYSE”), the NYSE Amex Equities (the “NYSE
Amex”), or the NASDAQ Stock Market (“NASDAQ”), or listed or quoted on an exchange or quotation system that is a successor to the NYSE, the NYSE Amex or NASDAQ. 

(b) In addition to any information required by law or by the applicable rules of any exchange upon which the Series E Preferred Stock may
be listed or admitted to trading, such notice shall state: (i) the redemption date; (ii) the redemption price; (iii) the number of shares of Series E Preferred Stock to be redeemed; (iv) the place or places where the
certificates, if any, representing shares of Series E Preferred Stock are to be surrendered for payment of the redemption price; (v) procedures for surrendering noncertificated shares of Series E Preferred Stock for payment of the redemption
price; (vi) that dividends on the shares of Series E Preferred Stock to be redeemed will cease to accumulate on the redemption date; (vii) that payment of the redemption price and any accumulated and unpaid dividends will be made upon
presentation and surrender of such Series E Preferred Stock; (viii) that the shares of Series E Preferred Stock are being redeemed pursuant to the Special Optional Redemption Right in connection with the occurrence of a Change of Control and a
brief description of the transaction or transactions constituting such Change of Control; and (ix) that holders of the shares of Series E Preferred Stock to which the notice relates will not be able to tender such shares of Series E Preferred
Stock for conversion in connection with the Change of Control and each share of Series E Preferred Stock tendered for conversion that is selected, prior to the Change of Control Conversion Date, for redemption will be redeemed on the related
redemption date instead of converted on the Change of Control Conversion Date. If fewer than all of the shares of Series E Preferred Stock held by any holder are to be redeemed, the notice mailed to such holder shall also specify the number of
shares of Series E Preferred Stock held by such holder to be redeemed. 
 If fewer than all of the outstanding shares of Series E
Preferred Stock are to be redeemed pursuant to the Special Optional Redemption Right, the shares to be redeemed shall be selected pro rata (as nearly as 

  
 6 

 
practicable without creating fractional shares) by lot or in such other equitable method determined by the Company that will not result in a violation of the Ownership Limit or the Aggregate
Stock Ownership Limit (each as defined in Section 9(a)). If such redemption pursuant to the Special Optional Redemption Right is to be by lot and, as a result, any holder of shares of Series E Preferred Stock would have actual ownership,
Beneficial Ownership or Constructive Ownership (each as defined in Section 9(a)) in excess of the Ownership Limit (as defined in Section 9(a)), the Aggregate Stock Ownership Limit (as defined in Section 9(a)), or such limit as
permitted by the Board of Directors or a committee thereof pursuant to Section 9(i), because such holder’s shares of Series E Preferred Stock were not redeemed, or were only redeemed in part then, except as otherwise provided in the
Charter, the Company shall redeem the requisite number of shares of Series E Preferred Stock of such holder such that no holder will hold an amount of Series E Preferred Stock in excess of the applicable ownership limit, subsequent to such
redemption. 
 (c) If the Company has given a notice of redemption pursuant to the Special Optional Redemption Right and has set
aside sufficient funds for the redemption in trust for the benefit of the holders of the Series E Preferred Stock called for redemption, then from and after the redemption date, those shares of Series E Preferred Stock will be treated as no longer
being outstanding, no further dividends will accrue and all other rights of the holders of those shares of Series E Preferred Stock will terminate. The holders of those shares of Series E Preferred Stock will retain their right to receive the
redemption price for their shares and any accrued and unpaid dividends through, but not including, the redemption date, without interest. So long as full cumulative dividends on the Series E Preferred Stock for all past dividend periods shall
have been or contemporaneously are (i) declared and paid in cash, or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for payment, nothing herein shall prevent or restrict the Company’s right or ability
to purchase, from time to time, either at a public or a private sale, all or any part of the Series E Preferred Stock at such price or prices as the Company may determine, subject to the provisions of applicable law, including the repurchase of
shares of Series E Preferred Stock in open-market transactions duly authorized by the Board of Directors. 
 (d) The holders of
Series E Preferred Stock at the close of business on a Dividend Record Date will be entitled to receive the dividend payable with respect to the Series E Preferred Stock on the corresponding Dividend Payment Date notwithstanding the redemption of
the Series E Preferred Stock pursuant to the Special Optional Redemption Right between such Dividend Record Date and the corresponding Dividend Payment Date or the Company’s default in the payment of the dividend due. Except as provided herein,
the Company shall make no payment or allowance for unpaid dividends, whether or not in arrears, on Series E Preferred Stock for which a notice of redemption pursuant to the Special Optional Redemption Right has been given. 

(e) All shares of the Series E Preferred Stock redeemed or repurchased pursuant to this Section 6, or otherwise acquired in any
other manner by the Company, shall be retired and shall be restored to the status of authorized but unissued shares of Preferred Stock, without designation as to series or class. 

Section 7. Voting Rights. 
 (a) Holders of the Series E Preferred Stock shall not have any voting rights, except as set forth in this Section 7. 
 (b) Whenever dividends on any shares of Series E Preferred Stock shall be in arrears for six or more consecutive or non-consecutive quarterly periods (a
“Preferred Dividend Default”), the holders of such Series E Preferred Stock (voting together as a single class with all other classes or series of preferred stock of the Company upon which like voting rights have been conferred and
are exercisable (“Parity Preferred”), including the Series C Cumulative Convertible Preferred Stock and the Series D Cumulative Convertible Preferred Stock of the Company) shall be entitled to vote for the election of a total of two
additional directors of the Company (the “Preferred Directors”) until all dividends accumulated on such Series E Preferred Stock and Parity Preferred for the past dividend periods shall have been fully paid or declared and a sum
sufficient for the payment thereof is set aside for payment. In such case, the entire Board of Directors will be increased by two directors. 
 (c) The Preferred Directors will be elected by a plurality of the votes cast in the election for a one-year term and each Preferred Director will serve until his or
her successor is duly elected and qualified or until such Preferred Director’s right to hold the office terminates, whichever occurs earlier, subject to such Preferred Director’s earlier death, disqualification, resignation or removal. The
election will take place at (i) either (A) a special meeting 

  
 7 

 
called in accordance with Section 7(d) below if the request is received more than 90 days before the date fixed for the Company’s next annual or special meeting of stockholders or
(B) the next annual or special meeting of stockholders if the request is received within 90 days of the date fixed for the Company’s next annual or special meeting of stockholders, and (ii) at each subsequent annual meeting of
stockholders, or special meeting held in place thereof, until all such dividends in arrears on the Series E Preferred Stock and each such class or series of outstanding Parity Preferred have been paid in full. A dividend in respect of Series E
Preferred Stock shall be considered timely made if made within two Business Days after the applicable Dividend Payment Date if at the time of such late payment date there shall not be any prior quarterly dividend periods in respect of which full
dividends were not timely made at the applicable Dividend Payment Date. 
 (d) At any time when such voting rights shall have
vested, a proper officer of the Company shall call or cause to be called, upon written request of holders of record of at least 10% of the outstanding shares of Series E Preferred Stock and Parity Preferred, a special meeting of the holders of
Series E Preferred Stock and each class or series of Parity Preferred by mailing or causing to be mailed to such holders a notice of such special meeting to be held not fewer than ten or more than 45 days after the date such notice is given. The
record date for determining holders of the Series E Preferred Stock and Parity Preferred entitled to notice of and to vote at such special meeting will be the close of business on the third Business Day preceding the day on which such notice is
mailed. At any such annual or special meeting, all of the holders of the Series E Preferred Stock and Parity Preferred, by plurality vote, voting together as a single class without regard to class or series will be entitled to elect two directors on
the basis of one vote per $25.00 of liquidation preference to which such Series E Preferred Stock and Parity Preferred are entitled by their terms (excluding amounts in respect of accumulated and unpaid dividends) and not cumulatively. The holder or
holders of one-third of the Series E Preferred Stock and Parity Preferred voting as a single class then outstanding, present in person or by proxy, will constitute a quorum for the election of the Preferred
Directors except as otherwise provided by law. Notice of all meetings at which holders of the Series E Preferred Stock and the Parity Preferred shall be entitled to vote will be given to such holders at their addresses as they appear in the transfer
records. At any such meeting or adjournment thereof in the absence of a quorum, subject to the provisions of any applicable law, a majority of the holders of the Series E Preferred Stock and Parity Preferred voting as a single class present in
person or by proxy shall have the power to adjourn the meeting for the election of the Preferred Directors, without notice other than an announcement at the meeting, until a quorum is present. If a Preferred Dividend Default shall terminate after
the notice of a special meeting has been given but before such special meeting has been held, the Company shall, as soon as practicable after such termination, mail or cause to be mailed notice of such termination to holders of the Series E
Preferred Stock and the Parity Preferred that would have been entitled to vote at such special meeting. 
 (e) If and when all
accumulated dividends on such Series E Preferred Stock and all classes or series of Parity Preferred for the past dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof is set aside for payment, the
right of the holders of Series E Preferred Stock and the Parity Preferred to elect such additional two directors shall immediately cease (subject to revesting in the event of each and every Preferred Dividend Default), and the term of office of each
Preferred Director so elected shall terminate and the entire Board of Directors shall be reduced accordingly. Any Preferred Director may be removed at any time with or without cause by the vote of, and shall not be removed otherwise than by the vote
of, the holders of record of a majority of the outstanding Series E Preferred Stock and the Parity Preferred entitled to vote thereon when they have the voting rights set forth in Section 7(b) (voting as a single class). So long as a Preferred
Dividend Default shall continue, any vacancy in the office of a Preferred Director may be filled by written consent of the Preferred Director remaining in office, or if none remains in office, by a vote of the holders of record of a majority of the
outstanding Series E Preferred Stock when they have the voting rights described above (voting as a single class with all other classes or series of Parity Preferred). Each of the Preferred Directors shall be entitled to one vote on any matter.

 (f) So long as any shares of Series E Preferred Stock remain outstanding, the affirmative vote or consent of the holders of two-thirds of the shares of Series E Preferred Stock and each other class or series of preferred stock ranking on parity with the Series E Preferred Stock with respect to the payment of dividends and the
distribution of assets upon liquidation, dissolution or winding up of the Company upon which like voting rights have been conferred outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting as a single class)
will be required to: (i) authorize, create or issue, or increase the number of authorized or issued shares of, any class or series of capital stock ranking senior to the Series E Preferred Stock with respect to payment of dividends or the
distribution of assets upon liquidation, dissolution or winding up of the Company or reclassify any authorized 

  
 8 

 
shares of capital stock of the Company into such capital stock, or create, authorize or issue any obligation or security convertible into or evidencing the right to purchase any such capital
stock; or (ii) amend, alter or repeal the provisions of the Charter or the terms of the Series E Preferred Stock, whether by merger, consolidation, transfer or conveyance of all or substantially all of its assets or otherwise (an
“Event”), so as to materially and adversely affect any right, preference, privilege or voting power of the Series E Preferred Stock; provided however, with respect to the occurrence of any of the Events set forth in
(ii) above, so long as the Series E Preferred Stock remains outstanding with the terms thereof materially unchanged, taking into account that, upon the occurrence of an Event, the Company may not be the surviving entity, the occurrence of such
Event shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting power of Series E Preferred Stock, and in such case such holders shall not have any voting rights with respect to the occurrence of any of
the Events set forth in (ii) above. In addition, if the holders of the Series E Preferred Stock receive the greater of the full trading price of the Series E Preferred Stock on the date of an Event set forth in (ii) above or the $25.00
liquidation preference per share of the Series E Preferred Stock pursuant to the occurrence of any of the Events set forth in (ii) above, then such holders shall not have any voting rights with respect to the Events set forth in
(ii) above. Holders of shares of Series E Preferred Stock shall not be entitled to vote with respect to (A) any increase in the total number of authorized shares of Common Stock or Preferred Stock of the Company, or (B) any increase
in the number of authorized shares of Series E Preferred Stock or the creation or issuance of any other class or series of capital stock, or (C) any increase in the number of authorized shares of any other class or series of capital stock, in
each case referred to in clause (A), (B) or (C) above ranking on parity with or junior to the Series E Preferred Stock with respect to the payment of dividends and the distribution of assets upon liquidation, dissolution or winding up of
the Company. Except as set forth herein, holders of the Series E Preferred Stock shall not have any voting rights with respect to, and the consent of the holders of the Series E Preferred Stock shall not be required for, the taking of any corporate
action, including an Event, regardless of the effect that such corporate action or Event may have upon the powers, preferences, voting power or other rights or privileges of the Series E Preferred Stock. 

(g) The foregoing voting provisions of this Section 7 shall not apply if, at or prior to the time when the act with respect to which
such vote would otherwise be required shall be effected, all outstanding shares of Series E Preferred Stock shall have been redeemed or called for redemption upon proper notice and sufficient funds, in cash, shall have been deposited in trust to
effect such redemption. 
 (h) In any matter in which the Series E Preferred Stock may vote (as expressly provided herein), each
share of Series E Preferred Stock shall be entitled to one vote per $25.00 of liquidation preference. 
 Section 8. Conversion.
The shares of Series E Preferred Stock are not convertible into or exchangeable for any other property or securities of the Company, except as provided in this Section 8. 
 (a) Upon the occurrence of a Change of Control, each holder of shares of Series E Preferred Stock shall have the right, unless, prior to the Change of Control Conversion Date, the Company has provided or
provides notice of its election to redeem the Series E Preferred Stock pursuant to the Redemption Right or Special Optional Redemption Right, to convert some or all of the Series E Preferred Stock held by such holder (the “Change of Control
Conversion Right”) on the Change of Control Conversion Date into a number of shares of Common Stock, per share of Series E Preferred Stock to be converted (the “Common Stock Conversion Consideration”) equal to the lesser of
(A) the quotient obtained by dividing (i) the sum of (x) the $25.00 liquidation preference per share of Series E Preferred Stock to be converted plus (y) the amount of any accrued and unpaid dividends to, but not including, the
Change of Control Conversion Date (unless the Change of Control Conversion Date is after a Dividend Record Date and prior to the corresponding Dividend Payment Date, in which case no additional amount for such accrued and unpaid dividends will be
included in such sum) by (ii) the Common Stock Price (as defined herein) and (B) 0.8378 (the “Share Cap”), subject to the immediately succeeding paragraph. 

The Share Cap is subject to pro rata adjustments for any share splits (including those effected pursuant to a distribution of the Common
Stock), subdivisions or combinations (in each case, a “Share Split”) with respect to the Common Stock as follows: the adjusted Share Cap as the result of a Share Split shall be the number of shares of Common Stock that is equivalent
to the product obtained by multiplying (i) the Share Cap in effect immediately prior to such Share Split by (ii) a fraction, the numerator of which is the number of shares of Common Stock outstanding after giving effect to such Share Split
and the denominator of which is the number of shares of Common Stock outstanding immediately prior to such Share Split. 

  
 9 

 For the avoidance of doubt, subject to the immediately succeeding sentence, the aggregate
number of shares of Common Stock (or equivalent Alternative Conversion Consideration (as defined below), as applicable) issuable in connection with the exercise of the Change of Control Conversion Right shall not exceed 8,378,000 shares of Common
Stock (or equivalent Alternative Conversion Consideration, as applicable), subject to increase to the extent the underwriters’ over-allotment option to purchase additional shares of Series E Preferred Stock in the initial public offering of
Series E Preferred Stock is exercised, not to exceed 9,634,700 shares of Common Stock in total (or equivalent Alternative Conversion Consideration, as applicable) (the “Exchange Cap”). The Exchange Cap is subject to pro rata
adjustments for any Share Splits on the same basis as the corresponding adjustment to the Share Cap. 
 In the case of a Change
of Control pursuant to which shares of Common Stock shall be converted into cash, securities or other property or assets (including any combination thereof) (the “Alternative Form Consideration”), a holder of shares of Series E
Preferred Stock shall receive upon conversion of such shares of Series E Preferred Stock the kind and amount of Alternative Form Consideration which such holder would have owned or been entitled to receive upon the Change of Control had such holder
held a number of shares of Common Stock equal to the Common Stock Conversion Consideration immediately prior to the effective time of the Change of Control (the “Alternative Conversion Consideration”; and the Common Stock Conversion
Consideration or the Alternative Conversion Consideration, as may be applicable to a Change of Control, shall be referred to herein as the “Conversion Consideration”). 

In the event that holders of Common Stock have the opportunity to elect the form of consideration to be received in the Change of
Control, the Conversion Consideration will be deemed to be the kind and amount of consideration actually received by holders of a majority of the Common Stock that voted for such an election (if electing between two types of consideration) or
holders of a plurality of the Common Stock that voted for such an election (if electing between more than two types of consideration), as the case may be, and will be subject to any limitations to which all holders of Common Stock are subject,
including, without limitation, pro rata reductions applicable to any portion of the consideration payable in the Change of Control. 
 The “Change of Control Conversion Date” shall be a Business Day set forth in the notice of Change of Control provided in accordance with Section 8(c) below that is no less than 20
days nor more than 35 days after the date on which the Company provides such notice pursuant to Section 8(c). 
 The
“Common Stock Price” shall be (i) if the consideration to be received in the Change of Control by the holders of Common Stock is solely cash, the amount of cash consideration per share of Common Stock or (ii) if the
consideration to be received in the Change of Control by holders of Common Stock is other than solely cash (x) the average of the closing sale prices per share of Common Stock (or, if no closing sale price is reported, the average of the
closing bid and ask prices or, if more than one in either case, the average of the average closing bid and the average closing ask prices) for the ten consecutive trading days immediately preceding, but not including, the effective date of the
Change of Control as reported on the principal U.S. securities exchange on which the Common Stock is then traded, or (y) the average of the last quoted bid prices for the Common Stock in the over-the-counter market as reported by Pink Sheets LLC or similar organization for the ten consecutive trading days immediately preceding, but not including, the effective date of the Change of Control, if
the Common Stock is not then listed for trading on a U.S. securities exchange. 
 (b) No fractional shares of Common Stock shall
be issued upon the conversion of Series E Preferred Stock. In lieu of fractional shares, holders shall be entitled to receive the cash value of such fractional shares based on the Common Stock Price. 

(c) Within 15 days following the occurrence of a Change of Control, a notice of occurrence of the Change of Control, describing the
resulting Change of Control Conversion Right, shall be delivered to the holders of record of the shares of Series E Preferred Stock at their addresses as they appear on the Company’s share transfer records and notice shall be provided to the
Company’s transfer agent. No failure to give such notice or any defect thereto or in the mailing thereof shall affect the validity of the proceedings for the conversion of any share of Series E Preferred Stock except as to the holder to whom
notice was defective or not given. Each notice shall state: (i) the events constituting the Change of Control; (ii) the date of the Change of Control; (iii) the last date on which the holders of Series E Preferred Stock may exercise
their Change of Control Conversion Right; (iv) the method and 

  
 10 

 
period for calculating the Common Stock Price; (v) the Change of Control Conversion Date, which shall be a Business Day occurring within 20 to 35 days following the date of such notice;
(vi) that if, prior to the Change of Control Conversion Date, the Company has provided or provides notice of its election to redeem all or any portion of the Series E Preferred Stock, the holder will not be able to convert shares of Series E
Preferred Stock designated for redemption and such shares of Series E Preferred Stock shall be redeemed on the related redemption date, even if they have already been tendered for conversion pursuant to the Change of Control Conversion Right;
(vii) if applicable, the type and amount of Alternative Conversion Consideration entitled to be received per share of Series E Preferred Stock; (viii) the name and address of the paying agent and the conversion agent; and (ix) the
procedures that the holders of Series E Preferred Stock must follow to exercise the Change of Control Conversion Right. 
 (d)
The Company shall issue a press release for publication on the Dow Jones & Company, Inc., Business Wire, PR Newswire 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), or post notice on the Company’s website, in any event prior to the opening of business on the first Business Day
following any date on which the Company provides notice pursuant to Section 8(c) above to the holders of Series E Preferred Stock. 
 (e) In order to exercise the Change of Control Conversion Right, a holder of shares of Series E Preferred Stock shall be required to deliver, on or before the close of business on the Change of Control
Conversion Date, the certificates (if any) representing the shares of Series E Preferred Stock to be converted, duly endorsed for transfer, together with a written conversion notice completed, to the Company’s transfer agent. Such notice shall
state: (i) the relevant Change of Control Conversion Date; (ii) the number of shares of Series E Preferred Stock to be converted; and (iii) that the shares of Series E Preferred Stock are to be converted pursuant to the applicable
provisions of these Articles Supplementary. Notwithstanding the foregoing, if the shares of Series E Preferred Stock are held in global form, such notice shall comply with applicable procedures of The Depository Trust Company
(“DTC”). 
 (f) Holders of Series E Preferred Stock may withdraw any notice of exercise of a Change of Control
Conversion Right (in whole or in part) by a written notice of withdrawal delivered to the Company’s transfer agent prior to the close of business on the Business Day prior to the Change of Control Conversion Date. The notice of withdrawal must
state: (i) the number of withdrawn shares of Series E Preferred Stock; (ii) if certificated shares of Series E Preferred Stock have been issued, the certificate numbers of the shares of withdrawn Series E Preferred Stock; and
(iii) the number of shares of Series E Preferred Stock, if any, which remain subject to the conversion notice. Notwithstanding the foregoing, if the shares of Series E Preferred Stock are held in global form, the notice of withdrawal shall
comply with applicable procedures of DTC. 
 (g) Shares of Series E Preferred Stock as to which the Change of Control Conversion
Right has been properly exercised and for which the conversion notice has not been properly withdrawn shall be converted into the applicable Conversion Consideration in accordance with the Change of Control Conversion Right on the Change of Control
Conversion Date, unless, prior to the Change of Control Conversion Date, the Company has provided or provides notice of its election to redeem such shares of Series E Preferred Stock, whether pursuant to its Redemption Right or Special Optional
Redemption Right. If the Company elects to redeem shares of Series E Preferred Stock that would otherwise be converted into the applicable Conversion Consideration on a Change of Control Conversion Date, such shares of Series E Preferred Stock shall
not be so converted and the holders of such shares shall be entitled to receive on the applicable redemption date $25.00 per share, plus any accrued and unpaid dividends thereon to, but not including, the redemption date. 

(h) The Company shall deliver the applicable Conversion Consideration no later than the third Business Day following the Change of
Control Conversion Date. 
 (i) Notwithstanding anything to the contrary contained herein, no holder of shares of Series E
Preferred Stock will be entitled to convert such shares of Series E Preferred Stock into shares of Common Stock to the extent that receipt of such shares of Common Stock would cause the holder of such shares of Common Stock (or any other person) to
have actual ownership, Beneficial Ownership or Constructive Ownership (each as defined in Section 9(a)) in excess of the Ownership Limit (as defined in Section 9(a)), the Aggregate Stock Ownership Limit (as defined in Section 9(a)),
or such other limit as permitted by the Board of Directors or the Committee pursuant to Section 9(i).

of the Code if the income derived by the Company (either directly or indirectly through one or more subsidiaries) from such tenant would cause the Company to fail to satisfy any of the gross income requirements of Section 856(c) of the Code).

 (ii) If, prior to the Restriction Termination Date, any Transfer or other event occurs that, if effective, would result in
any Person Beneficially or Constructively Owning Series E Preferred Stock in violation of Section 9(b)(i) of these Articles Supplementary, (A) then that number of shares of Series E Preferred Stock that otherwise would cause such Person to
violate Section 9(b)(i) of these Articles Supplementary (rounded up to the nearest whole share) shall be automatically transferred to a Trust for the benefit of a Charitable Beneficiary, as described in Section 9(c), effective as of the
close of business on the Business Day prior to the date of such Transfer or other event, and such Purported Beneficial Transferee shall thereafter have no rights in such shares or (B) if, for any reason, the transfer to the Trust described in
clause (A) of this sentence is not automatically effective as provided therein to prevent any Person from Beneficially or Constructively Owning Series E Preferred Stock in violation of Section 9(b)(i) of these Articles Supplementary, then
the Transfer of that number of shares of Series E Preferred Stock that otherwise would cause any Person to violate Section 9(b)(i) shall be void ab initio, and the Purported Beneficial Transferee shall have no rights in such shares. 

(iii) Subject to Section 9(l) and prior to the Restriction Termination Date, any Transfer of Series E Preferred Stock that, if
effective, would result in the capital stock of the Company being beneficially owned by fewer than 100 Persons (determined without reference to any rules of attribution) shall be void ab initio, and the intended transferee shall acquire no rights in
such Series E Preferred Stock. 
 (c) Transfers of Series E Preferred Stock in Trust. 

(i) Upon any purported Transfer or other event described in Section 9(b)(ii) of these Articles Supplementary, such Series E
Preferred Stock shall be deemed to have been transferred to the Trustee in his capacity as trustee of a Trust for the exclusive benefit of one or more Charitable Beneficiaries. Such transfer to the Trustee shall be deemed to be effective as of the
close of business on the Business Day prior to the purported Transfer or other event that results in a transfer to the Trust pursuant to Section 9(b)(ii). The Trustee shall be appointed by the Company and shall be a Person unaffiliated with the
Company, any Purported Beneficial Transferee or any Purported Record Transferee. Each Charitable Beneficiary shall be designated by the Company as provided in Section 9(c)(vi) of these Articles Supplementary. 

(ii) Series E Preferred Stock held by the Trustee shall be issued and outstanding Series E Preferred Stock of the Company. The Purported
Beneficial Transferee or Purported Record Transferee shall have no rights in the shares of the Series E Preferred Stock held by the Trustee. The Purported Beneficial Transferee or Purported Record Transferee shall not benefit economically from
ownership of any shares held in trust by the Trustee, shall have no rights to dividends and shall not possess any rights to vote or other rights attributable to the shares of Series E Preferred Stock held in the Trust. 

(iii) The Trustee shall have all voting rights and rights to dividends with respect to Series E Preferred Stock held in the Trust, which
rights shall be exercised for the exclusive benefit of the Charitable Beneficiary. Any dividend or distribution paid to or on behalf of the Purported Record Transferee or Purported Beneficial Transferee prior to the discovery by the Company that
shares of Series E Preferred Stock have been transferred to the Trustee shall be paid to the Trustee upon demand, and any dividend or distribution declared but unpaid shall be paid when due to the Trustee with respect to such Series E Preferred
Stock. Any dividends or distributions so paid over to the Trustee shall be held in trust for the Charitable Beneficiary. The Purported Record Transferee and Purported Beneficial Transferee shall have no voting rights with respect to the Series E
Preferred Stock held in the Trust and, subject to Maryland law, effective as of the date the Series E Preferred Stock has been transferred to the Trustee, the Trustee shall have the authority (at the Trustee’s sole discretion) (A) to
rescind as void 

  
 14 

 
any vote cast by a Purported Record Transferee with respect to such Series E Preferred Stock prior to the discovery by the Company that the Series E Preferred Stock has been transferred to the
Trustee and (B) to recast such vote in accordance with the desires of the Trustee acting for the benefit of the Charitable Beneficiary; provided, however, that if the Company has already taken irreversible corporate action, then
the Trustee shall not have the authority to rescind and recast such vote. Notwithstanding any other provision of these Articles Supplementary to the contrary, until the Company has received notification that the Series E Preferred Stock has been
transferred into a Trust, the Company shall be entitled to rely on its share transfer and other stockholder records for purposes of preparing lists of stockholders entitled to vote at meetings, determining the validity and authority of proxies and
otherwise conducting votes of stockholders. 
 (iv) Within twenty (20) days of receiving notice from the Company that
shares of Series E Preferred Stock have been transferred to the Trust, the Trustee of the Trust shall sell the shares of Series E Preferred Stock held in the Trust to a Person, designated by the Trustee, whose ownership of the shares of Series E
Preferred Stock will not violate the ownership limitations set forth in Section 9(b)(i). Upon such sale, the interest of the Charitable Beneficiary in the shares of Series E Preferred Stock sold shall terminate and the Trustee shall distribute
the net proceeds of the sale to the Purported Record Transferee and to the Charitable Beneficiary as provided in this Section 9(c)(iv). The Purported Record Transferee shall receive the lesser of (A) the price paid by the Purported Record
Transferee for the shares of Series E Preferred Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Series E Preferred Stock
at Market Price, the Market Price of such shares of Series E Preferred Stock on the day of the event which resulted in the transfer of such shares of Series E Preferred Stock to the Trust) and (B) the price per share received by the Trustee
(net of any commissions and other expenses of sale) from the sale or other disposition of the shares of Series E Preferred Stock held in the Trust. The Trustee may reduce the amount payable to the Purported Record Transferee by the amount of
dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 9(c)(iii). Any net sales proceeds in excess of the amount payable to the
Purported Record Transferee shall be immediately paid to the Charitable Beneficiary together with any dividends or other distributions thereon. If, prior to the discovery by the Company that shares of such Series E Preferred Stock have been
transferred to the Trustee, such shares of Series E Preferred Stock are sold by a Purported Record Transferee then (1) such shares of Series E Preferred Stock shall be deemed to have been sold on behalf of the Trust and (2) to the extent
that the Purported Record Transferee received an amount for such shares of Series E Preferred Stock that exceeds the amount that such Purported Record Transferee was entitled to receive pursuant to this Section 9(c)(iv), such excess shall be
paid to the Trustee upon demand. 
 (v) Series E Preferred Stock transferred to the Trustee shall be deemed to have been offered
for sale to the Company, or its designee, at a price per share equal to the lesser of (A) the price paid by the Purported Record Transferee for the shares of Series E Preferred Stock in the transaction that resulted in such transfer to the
Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Series E Preferred Stock at Market Price, the Market Price of such shares of Series E Preferred Stock on the day of the event which
resulted in the transfer of such shares of Series E Preferred Stock to the Trust) and (B) the Market Price on the date the Company, or its designee, accepts such offer. The Company may reduce the amount payable to the Purported Record
Transferee by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 9(c)(iii). The Company shall have the right to
accept such offer until the Trustee has sold the shares of Series E Preferred Stock held in the Trust pursuant to Section 9(c)(iv). Upon such a sale to the Company, the interest of the Charitable Beneficiary in the shares of Series E Preferred
Stock sold shall terminate and the Trustee shall distribute the net proceeds of the sale to the Purported Record Transferee and any dividends or other distributions held by the Trustee with respect to such Series E Preferred Stock shall thereupon be
paid to the Charitable Beneficiary. 
 (vi) By written notice to the Trustee, the Company shall designate one or more nonprofit
organizations to be the Charitable Beneficiary of the interest in the Trust such that the Series E Preferred Stock held in the Trust would not violate the restrictions set forth in Section 9(b)(i) in the hands of such Charitable Beneficiary.

 (d) Remedies For Breach. If the Board of Directors or a committee thereof or other designees if permitted by the MGCL
shall at any time determine in good faith that a Transfer or other event has taken place in violation of Section 9(b) of these Articles Supplementary or that a Person intends to acquire, has attempted to acquire or may

  
 15 

 
acquire beneficial ownership (determined without reference to any rules of attribution), Beneficial Ownership or Constructive Ownership of any shares of Series E Preferred Stock of the Company in
violation of Section 9(b) of these Articles Supplementary, the Board of Directors or the Committee or other designees if permitted by the MGCL shall take such action as it deems advisable to refuse to give effect or to prevent such Transfer,
including, but not limited to, causing the Company to redeem shares of Series E Preferred Stock, refusing to give effect to such Transfer on the books of the Company or instituting proceedings to enjoin such Transfer; provided,
however, that any Transfers (or, in the case of events other than a Transfer, ownership or Constructive Ownership or Beneficial Ownership) in violation of Section 9(b)(i) of these Articles Supplementary, shall automatically result in the
transfer to a Trust as described in Section 9(b)(ii) and any Transfer in violation of Section 9(b)(iii) shall automatically be void ab initio irrespective of any action (or non-action) by the Board
of Directors. 
 (e) Notice of Restricted Transfer. Any Person who acquires or attempts to acquire shares of Series E
Preferred Stock in violation of Section 9(b) of these Articles Supplementary, or any Person who is a Purported Beneficial Transferee such that an automatic transfer to a Trust results under Section 9(b)(ii) of these Articles Supplementary,
shall immediately give written notice to the Company of such event and shall provide to the Company such other information as the Company may request in order to determine the effect, if any, of such Transfer or attempted Transfer on the
Company’s status as a REIT. 
 (f) Owners Required To Provide Information. Prior to the Restriction Termination Date
each Person who is a beneficial owner or Beneficial Owner or Constructive Owner of Series E Preferred Stock and each Person (including the stockholder of record) who is holding Series E Preferred Stock for a beneficial owner or Beneficial Owner or
Constructive Owner shall provide to the Company such information that the Company may request, in good faith, in order to determine the Company’s status as a REIT. 
 (g) Remedies Not Limited. Nothing contained in these Articles Supplementary (but subject to Section 9(l) of these Articles Supplementary) shall limit the authority of the Board of Directors to
take such other action as it deems necessary or advisable to protect the Company and the interests of its stockholders by preservation of the Company’s status as a REIT. 
 (h) Ambiguity. In the case of an ambiguity in the application of any of the provisions of this Section 9 of these Articles Supplementary, including any definition contained in
Section 9(a), the Board of Directors shall have the power to determine the application of the provisions of this Section 9 with respect to any situation based on the facts known to it (subject, however, to the provisions of
Section 9(l) of these Articles Supplementary). In the event Section 9 requires an action by the Board of Directors and these Articles Supplementary fail to provide specific guidance with respect to such action, the Board of Directors shall
have the power to determine the action to be taken so long as such action is not contrary to the provisions of Section 9. Absent a decision to the contrary by the Board of Directors (which the Board of Directors may make in its sole and
absolute discretion), if a Person would have (but for the remedies set forth in Section 9(b)) acquired Beneficial or Constructive Ownership of Series E Preferred Stock in violation of Section 9(b)(i), such remedies (as applicable) shall
apply first to the shares of Series E Preferred Stock which, but for such remedies, would have been actually owned by such Person, and second to shares of Series E Preferred Stock, which, but for such remedies, would have been Beneficially Owned or
Constructively Owned (but not actually owned) by such Person, pro rata among the Persons who actually own such shares of Series E Preferred Stock based upon the relative number of the shares of Series E Preferred Stock held by each such Person.

 (i) Exceptions. 
 (i) Subject to Section 9(b)(i)(C), the Board of Directors, in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Beneficially Owning shares of
Series E Preferred Stock in violation of Section 9(b)(i)(A) if the Board of Directors determines that such exemption will not cause any Individual’s Beneficial Ownership of shares of Capital Stock to violate the Aggregate Stock Ownership
Limit and that such exemption will not cause the Company to fail to qualify as a REIT under the Code. 
 (ii) Subject to
Section 9(b)(i)(C), the Board of Directors in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Constructively Owning shares of Series E

  
 16 

 
Preferred Stock in violation of Section 9(b)(i)(B), if the Board of Directors determines that such ownership would not cause the Company to fail to qualify as a REIT under the Code.

 (iii) Subject to Section 9(b)(i)(C) and the remainder of this Section 9(i)(iii), the Board of Directors may from
time to time increase or decrease the Ownership Limit; provided, however, that the decreased Ownership Limit will not be effective for any Person whose percentage ownership of Series E Preferred Stock is in excess of such decreased
Ownership Limit until such time as such Person’s percentage of Series E Preferred Stock equals or falls below the decreased Ownership Limit, but any further acquisition of Series E Preferred Stock in excess of such percentage ownership of
Series E Preferred Stock will be in violation of the Ownership Limit, and, provided further, that the new Ownership Limit would not allow five or fewer Persons to Beneficially Own more than 49% in value of the outstanding capital stock of the
Company. 
 (iv) In granting a Person an exemption under Section 9(i)(i) or (ii) above, the Board of Directors may
require such Person to make certain representations or undertakings or to agree that any violation or attempted violation of such representations or undertakings (or other action which is contrary to the restrictions contained in Section 9(b)
of these Articles Supplementary) will result in such Series E Preferred Stock being transferred to a Trust in accordance with Section 9(b)(ii) of these Articles Supplementary. In granting any exception pursuant to Section 9(i)(i) or
(ii) of these Articles Supplementary, the Board of Directors may require a ruling from the IRS, or an opinion of counsel, in either case in form and substance satisfactory to the Board of Directors in its sole discretion, as it may deem
necessary or advisable in order to determine or ensure the Company’s status as a REIT. 
 (j) Legends. Each
certificate for Series E Preferred Stock shall bear substantially the following legends in addition to any legends required to comply with federal and state securities laws:

AT ITS PRINCIPAL OFFICE.” 
 (k) Severability. If any provision of this Section 9 or any application of any
such provision is determined to be invalid by any federal or state court having jurisdiction over the issues, the validity of the remaining provisions shall not be affected and other applications of such provision shall be affected only to the
extent necessary to comply with the determination of such court.

Series F Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company. The term “capital stock” does not include convertible or exchangeable debt securities,
which will rank senior to the Series F Preferred Stock prior to conversion or exchange. The Series F Preferred Stock will also rank junior in right of payment to the Company’s other existing and future debt obligations. 

Section 3. Dividends. 
 (a) Subject to the preferential rights of the holders of any class or series of capital stock of the Company ranking senior to the Series F Preferred Stock as to dividends, the holders of shares of the
Series F Preferred Stock shall be entitled to receive, when, as and if authorized by the Board of Directors and declared by the Company, out of funds legally available for the payment of dividends, cumulative cash dividends at the rate of
6.625% per annum of the $25.00 liquidation preference per share of the Series F Preferred Stock (equivalent to a fixed annual amount of $1.65625 per share of the Series F Preferred Stock). Such dividends shall accrue and be cumulative from and
including the first date on which any shares of Series F Preferred Stock are issued (the “Original Issue Date”) and shall be payable quarterly in arrears on each Dividend Payment Date (as defined below), commencing June 30,
2012; provided, however, that if any Dividend Payment Date is not a Business Day (as defined below), then the dividend which would otherwise have been payable on such Dividend Payment Date may be paid on the next succeeding Business
Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case 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. The amount of any dividend payable on the Series F Preferred Stock for any partial Dividend
Period (as defined below) shall be prorated and computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends will be payable to holders of
record as they appear in the stockholder records of the Company at the close of business on the applicable Dividend Record Date (as defined below). Notwithstanding any provision to the contrary contained herein, each outstanding share of Series F
Preferred Stock shall be entitled to receive a dividend with respect to any Dividend Record Date equal to the dividend paid with respect to each other share of Series F Preferred Stock that is outstanding on such date. “Dividend Record
Date” shall mean the date designated by the Board of Directors for the payment of dividends that is not more than 35 or fewer than 10 days prior to the applicable Dividend Payment Date. “Dividend Payment Date” shall mean
the last calendar day of each March, June, September and December, commencing on June 30, 2012. “Dividend Period” shall mean the respective periods commencing on and including the first day of January, April, July and October
of each year and ending on and including the day preceding the first day of the next succeeding Dividend Period (other than the initial Dividend Period, which shall commence on the Original Issue Date and end on and include June 30, 2012, and
other than the Dividend Period during which any shares of Series F Preferred Stock shall be redeemed pursuant to Section 5 or Section 6, which shall end on and include the day preceding the call date with respect to the shares of Series F
Preferred Stock being redeemed). 
 The term “Business Day” shall mean each day, other than a Saturday or a
Sunday, which is not a day on which banking institutions in New York, New York are authorized or required by law, regulation or executive order to close. 
 (b) Notwithstanding anything contained herein to the contrary, dividends on the Series F Preferred Stock shall accrue whether or not the Company has earnings, whether or not there are funds legally
available for the payment of such dividends, and whether or not such dividends are authorized or declared. 
 (c) Except as
provided in Section 3(d) below, no dividends shall be declared and paid or declared and set 

  
 2 

 
apart for payment, and no other distribution of cash or other property may be declared and made, directly or indirectly, on or with respect to, any shares of Common Stock or shares of any other
class or series of capital stock of the Company ranking, as to dividends, on parity with or junior to the Series F Preferred Stock (other than a dividend paid in shares of Common Stock or in shares of any other class or series of capital stock
ranking junior to the Series F Preferred Stock as to dividends and upon liquidation) for any period, nor shall any shares of Common Stock or any other shares of any other class or series of capital stock of the Company ranking, as to dividends or
upon liquidation, on parity with or junior to the Series F Preferred Stock be redeemed, purchased or otherwise acquired for any consideration, nor shall any funds be paid or made available for a sinking fund for the redemption of such shares, and no
other distribution of cash or other property may be made, directly or indirectly, on or with respect thereto by the Company (except by conversion into or exchange for other shares of any class or series of capital stock of the Company ranking junior
to the Series F Preferred Stock as to dividends and upon liquidation, and except for the acquisition of shares made pursuant to the provisions of Article VI of the Charter or Section 9 hereof), unless full cumulative dividends on the Series F
Preferred Stock for all past dividend periods shall have been or contemporaneously are (i) declared and paid in cash or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for such payment. 

(d) When dividends are not paid in full (and a sum sufficient for such full payment is not so set apart) on the Series F Preferred Stock
and the shares of any other class or series of capital stock ranking, as to dividends, on parity with the Series F Preferred Stock, all dividends declared upon the Series F Preferred Stock and each such other class or series of capital stock
ranking, as to dividends, on parity with the Series F Preferred Stock shall be declared pro rata so that the amount of dividends declared per share of Series F Preferred Stock and such other class or series of capital stock shall in all cases bear
to each other the same ratio that accrued dividends per share on the Series F Preferred Stock and such other class or series of capital stock (which shall not include any accrual in respect of unpaid dividends on such other class or series of
capital stock for prior dividend periods if such other class or series of capital stock does not have a cumulative dividend) bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or
payments on the Series F Preferred Stock which may be in arrears. 
 (e) Holders of shares of Series F Preferred Stock shall not
be entitled to any dividend, whether payable in cash, property or shares of capital stock, in excess of full cumulative dividends on the Series F Preferred Stock as provided herein. Any dividend payment made on the Series F Preferred Stock shall
first be credited against the earliest accrued but unpaid dividends due with respect to such shares which remain payable. Accrued but unpaid distributions on the Series F Preferred Stock will accumulate as of the Dividend Payment Date on which they
first become payable. 
 Section 4. Liquidation Preference. 

(a) Upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, before any distribution or payment shall be
made to holders of shares of Common Stock or any other class or series of capital stock of the Company ranking, as to rights upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, junior to the Series F Preferred
Stock, the holders of shares of Series F Preferred Stock shall be entitled to be paid out of the assets of the Company legally available for distribution to its stockholders, after payment of or provision for the debts and other liabilities of the
Company, a liquidation preference of $25.00 per share, plus an amount equal to any accrued and unpaid dividends (whether or not authorized or declared) to but excluding the date of payment. In the event that, upon such voluntary or involuntary
liquidation, dissolution or winding up, the available assets of the Company are insufficient to pay the full amount of the liquidating distributions on all outstanding shares of Series F Preferred Stock and the corresponding amounts payable on all
shares of other classes or series of capital stock of the Company ranking, as to liquidation rights, on parity with the Series F Preferred Stock in the distribution of assets, then the holders of the Series F Preferred Stock and each such other
class or series of capital stock ranking, as to rights upon any voluntary or involuntary liquidation, dissolution or winding up, on parity with the Series F Preferred Stock shall share ratably in any such distribution of assets in proportion to the
full liquidating distributions to which they would otherwise be respectively entitled. Written notice of any such voluntary or involuntary liquidation, dissolution or winding up of the Company, stating the payment date or dates when, and the place
or places where, the amounts distributable in such circumstances shall be payable, 

  
 3 

 
shall be given by first class mail, postage pre-paid, not fewer than 30 or more than 60 days prior to the payment date stated therein, to each record
holder of shares of Series F Preferred Stock at the respective addresses of such holders as the same shall appear on the stock transfer records of the Company. After payment of the full amount of the liquidating distributions to which they are
entitled, the holders of Series F Preferred Stock will have no right or claim to any of the remaining assets of the Company. The consolidation or merger of the Company with or into any other corporation, trust or entity, or the voluntary sale,
lease, transfer or conveyance of all or substantially all of the property or business of the Company, shall not be deemed to constitute a liquidation, dissolution or winding up of the Company. 

(b) In determining whether a distribution (other than upon voluntary or involuntary liquidation), by dividend, redemption or other
acquisition of shares of capital stock of the Company or otherwise, is permitted under the MGCL, amounts that would be needed, if the Company were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution
of holders of shares of Series F Preferred Stock shall not be added to the Company’s total liabilities. 
 Section 5.
Redemption. 
 (a) Shares of Series F Preferred Stock shall not be redeemable prior to April 5, 2017 except as set
forth in Section 6 or to preserve the status of the Company as a REIT (as defined in Section 9(a)) for United States federal income tax purposes. In addition, the Series F Preferred Stock shall be subject to the provisions of
Section 9 pursuant to which Series F Preferred Stock owned by a stockholder in excess of the Ownership Limit (as defined in Section 9(a)) shall automatically be transferred to a Trust (as defined in Section 9(a)) for the exclusive
benefit of a Charitable Beneficiary (as defined in Section 9(a)). 
 (b) On and after April 5, 2017, the Company, at
its option upon not fewer than 30 or more than 60 days’ written notice, may redeem the Series F Preferred Stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and
unpaid dividends (whether or not authorized or declared) thereon up to but not including the date fixed for redemption, without interest, to the extent the Company has funds legally available therefor (the “Redemption Right”). If
fewer than all of the outstanding shares of Series F Preferred Stock are to be redeemed, the shares of Series F Preferred Stock to be redeemed shall be redeemed pro rata (as nearly as may be practicable without creating fractional shares) by lot or
by any other equitable method determined by the Company that will not result in a violation of the Ownership Limit or the Aggregate Stock Ownership Limit (each as defined in Section 9(a)). If redemption is to be by lot and, as a result, any
holder of shares of Series F Preferred Stock would have actual ownership, Beneficial Ownership or Constructive Ownership (each as defined in Section 9(a)) in excess of the Ownership Limit (as defined in Section 9(a)), the Aggregate Stock
Ownership Limit (as defined in Section 9(a)), or such other limit as permitted by the Board of Directors or the Committee pursuant to Section 9(i), because such holder’s shares of Series F Preferred Stock were not redeemed, or were
only redeemed in part, then, except as otherwise provided in the Charter, the Company shall redeem the requisite number of shares of Series F Preferred Stock of such holder such that no holder will hold an amount of Series F Preferred Stock in
excess of the applicable ownership limit, subsequent to such redemption. Holders of Series F Preferred Stock to be redeemed shall surrender such Series F Preferred Stock at the place, or in accordance with the book entry procedures, designated in
such notice and shall be entitled to the redemption price of $25.00 per share and any accrued and unpaid dividends payable upon such redemption following such surrender. If (i) notice of redemption of any shares of Series F Preferred Stock has
been given (in the case of a redemption of the Series F Preferred Stock other than to preserve the status of the Company as a REIT), (ii) the funds necessary for such redemption have been set aside by the Company in trust for the benefit of the
holders of any shares of Series F Preferred Stock so called for redemption, and (iii) irrevocable instructions have been given to pay the redemption price and all accrued and unpaid dividends, then from and after the redemption date, dividends
shall cease to accrue on such shares of Series F Preferred Stock, such shares of Series F Preferred Stock shall no longer be deemed outstanding, and all rights of the holders of such shares shall terminate, except the right to receive the redemption
price plus any accrued and unpaid dividends payable upon such redemption, without interest. So long as full cumulative dividends on the Series F Preferred Stock for all past dividend periods shall have been or contemporaneously are (i) declared
and paid in cash, or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for payment, nothing herein shall prevent or restrict the Company’s right or ability to purchase,

  
 4 

 
from time to time, either at a public or a private sale, all or any part of the Series F Preferred Stock at such price or prices as the Company may determine, subject to the provisions of
applicable law, including the repurchase of shares of Series F Preferred Stock in open-market transactions duly authorized by the Board of Directors. 
 (c) In the event of any redemption of the Series F Preferred Stock in order to preserve the status of the Company as a REIT for United States federal income tax purposes, such redemption shall be made in
accordance with the terms and conditions set forth in this Section 5 of these Articles Supplementary. If the Company calls for redemption any shares of Series F Preferred Stock pursuant to and in accordance with this Section 5(c), then the
redemption price for such shares will be an amount in cash equal to $25.00 per share together with all accrued and unpaid dividends to but excluding the dated fixed for redemption. 

(d) Unless full cumulative dividends on the Series F Preferred Stock for all past dividend periods shall have been or contemporaneously
are (i) declared and paid in cash, or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for payment, no shares of Series F Preferred Stock shall be redeemed pursuant to the Redemption Right or Special Optional
Redemption Right (defined below) unless all outstanding shares of Series F Preferred Stock are simultaneously redeemed, and the Company shall not purchase or otherwise acquire directly or indirectly any shares of Series F Preferred Stock or any
class or series of capital stock of the Company ranking, as to dividends or upon liquidation, on parity with or junior to the Series F Preferred Stock (except by conversion into or exchange for shares of capital stock of the Company ranking, as to
dividends and upon liquidation, junior to the Series F Preferred Stock); provided, however, that the foregoing shall not prevent the purchase of Series F Preferred Stock, or any other class or series of capital stock of the Company
ranking, as to dividends or upon liquidation, on parity with or junior to the Series F Preferred Stock, by the Company in accordance with the terms of Sections 5(c) and 9 of these Articles Supplementary or otherwise, in order to ensure that the
Company remains qualified as a REIT for United States federal income tax purposes, or the purchase or acquisition of Series F Preferred Stock pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding shares of
Series F Preferred Stock. 
 (e) Notice of redemption pursuant to the Redemption Right will be given by publication in a
newspaper of general circulation in the City of New York, such publication to be made once a week for two successive weeks commencing not fewer than 30 or more than 60 days prior to the redemption date. A similar notice will be mailed by the
Company, postage prepaid, not fewer than 30 or more than 60 days prior to the redemption date, addressed to the respective holders of record of the Series F Preferred Stock to be redeemed at their respective addresses as they appear on the transfer
records of the Company. No failure to give or defect in such notice shall affect the validity of the proceedings for the redemption of any Series F Preferred Stock except as to the holder to whom such notice was defective or not given. In addition
to any information required by law or by the applicable rules of any exchange upon which the Series F Preferred Stock may be listed or admitted to trading, each such notice shall state: (i) the redemption date; (ii) the redemption price;
(iii) the number of shares of Series F Preferred Stock to be redeemed; (iv) the place or places where the certificates, if any, representing shares of Series F Preferred Stock are to be surrendered for payment of the redemption price;
(v) procedures for surrendering noncertificated shares of Series F Preferred Stock for payment of the redemption price; (vi) that dividends on the shares of Series F Preferred Stock to be redeemed will cease to accumulate on such
redemption date; and (vii) that payment of the redemption price and any accumulated and unpaid dividends will be made upon presentation and surrender of such Series F Preferred Stock. If fewer than all of the shares of Series F Preferred Stock
held by any holder are to be redeemed, the notice mailed to such holder shall also specify the number of shares of Series F Preferred Stock held by such holder to be redeemed. Notwithstanding anything else to the contrary in these Articles
Supplementary, the Company shall not be required to provide notice to the holder of Series F Preferred Stock in the event such holder’s Series F Preferred Stock is redeemed in accordance with Sections 5(c) and 9 of these Articles Supplementary
to preserve the Company’s status as a REIT. 
 (f) If a redemption date falls after a Dividend Record Date and on or prior
to the corresponding Dividend Payment Date, each holder of Series F Preferred Stock at the close of business of such Dividend Record Date shall be entitled to the dividend payable on such shares on the corresponding Dividend Payment Date
notwithstanding the redemption of such shares on or prior to such Dividend Payment Date, and each holder of Series F Preferred Stock that surrenders its shares on such redemption date will be entitled to the dividends accruing after the end of the

  
 5 

 
Dividend Period to which such Dividend Payment Date relates up to but excluding the redemption date. Except as provided herein, the Company shall make no payment or allowance for unpaid
dividends, whether or not in arrears, on Series F Preferred Stock for which a notice of redemption has been given. 
 (g) All
shares of the Series F Preferred Stock redeemed or repurchased pursuant to this Section 5, or otherwise acquired in any other manner by the Company, shall be retired and shall be restored to the status of authorized but unissued shares of
Preferred Stock, without designation as to series or class. 
 (h) The Series F Preferred Stock shall have no stated maturity
and shall not be subject to any sinking fund or mandatory redemption; provided, however, that the Series F Preferred Stock owned by a stockholder in excess of the applicable ownership limit shall be subject to the provisions of this
Section 5 and Section 9 of these Articles Supplementary. 
 Section 6. Special Optional Redemption by the
Company. 
 (a) Upon the occurrence of a Change of Control (as defined below), the Company will have the option upon written
notice mailed by the Company, postage pre-paid, no fewer than 30 nor more than 60 days prior to the redemption date and addressed to the holders of record of shares of the Series F Preferred Stock to be
redeemed at their respective addresses as they appear on the share transfer records of the Company, to redeem shares of the Series F Preferred Stock, in whole or in part within 120 days after the first date on which such Change of Control occurred,
for cash at $25.00 per share plus accrued and unpaid dividends, if any, to, but not including, the redemption date (“Special Optional Redemption Right”). No failure to give such notice or any defect thereto or in the mailing thereof
shall affect the validity of the proceedings for the redemption of any shares of Series F Preferred Stock except as to the holder to whom notice was defective or not given. If, prior to the Change of Control Conversion Date (as defined below), the
Company has provided or provides notice of redemption with respect to the Series F Preferred Stock (whether pursuant to the Redemption Right or the Special Optional Redemption Right), the holders of shares of Series F Preferred Stock will not have
the conversion right described below in Section 8. 
 A “Change of Control” is when, after the original
issuance of the Series F Preferred Stock, the following have occurred and are continuing: 
 (i) the acquisition by any person,
including any syndicate or group deemed to be a “person” under Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), of beneficial ownership, directly or indirectly, through a
purchase, merger or other acquisition transaction or series of purchases, mergers or other acquisition transactions of stock of the Company entitling that person to exercise more than 50% of the total voting power of all stock of the Company
entitled to vote generally in the election of the Company’s directors (except that such person will be deemed to have beneficial ownership of all securities that such person has the right to acquire, whether such right is currently exercisable
or is exercisable only upon the occurrence of a subsequent condition); and 
 (ii) following the closing of any transaction
referred to in (i) above, neither the Company nor the acquiring or surviving entity has a class of common securities (or American Depositary Receipts representing such securities) listed on the New York Stock Exchange (the
“NYSE”), the NYSE Amex Equities (the “NYSE Amex”), or the NASDAQ Stock Market (“NASDAQ”), or listed or quoted on an exchange or quotation system that is a successor to the NYSE, the NYSE Amex or
NASDAQ. 
 (b) In addition to any information required by law or by the applicable rules of any exchange upon which the Series F
Preferred Stock may be listed or admitted to trading, such notice shall state: (i) the redemption date; (ii) the redemption price; (iii) the number of shares of Series F Preferred Stock to be redeemed; (iv) the place or places
where the certificates, if any, representing shares of Series F Preferred Stock are to be surrendered for payment of the redemption price; (v) procedures for surrendering noncertificated shares of Series F Preferred Stock for payment of the
redemption price; (vi) that dividends on the shares of Series F Preferred Stock to be redeemed will cease to accumulate on the redemption date; (vii) that payment of the redemption price and any accumulated and unpaid dividends will be
made upon presentation and surrender of such Series F Preferred Stock; (viii) that the shares of 

  
 6 

 
Series F Preferred Stock are being redeemed pursuant to the Special Optional Redemption Right in connection with the occurrence of a Change of Control and a brief description of the transaction
or transactions constituting such Change of Control; and (ix) that holders of the shares of Series F Preferred Stock to which the notice relates will not be able to tender such shares of Series F Preferred Stock for conversion in connection
with the Change of Control and each share of Series F Preferred Stock tendered for conversion that is selected, prior to the Change of Control Conversion Date, for redemption will be redeemed on the related redemption date instead of converted on
the Change of Control Conversion Date. If fewer than all of the shares of Series F Preferred Stock held by any holder are to be redeemed, the notice mailed to such holder shall also specify the number of shares of Series F Preferred Stock held by
such holder to be redeemed. 
 If fewer than all of the outstanding shares of Series F Preferred Stock are to be redeemed
pursuant to the Special Optional Redemption Right, the shares to be redeemed shall be selected pro rata (as nearly as practicable without creating fractional shares) by lot or in such other equitable method determined by the Company that will not
result in a violation of the Ownership Limit or the Aggregate Stock Ownership Limit (each as defined in Section 9(a)). If such redemption pursuant to the Special Optional Redemption Right is to be by lot and, as a result, any holder of shares
of Series F Preferred Stock would have actual ownership, Beneficial Ownership or Constructive Ownership (each as defined in Section 9(a)) in excess of the Ownership Limit (as defined in Section 9(a)), the Aggregate Stock Ownership Limit
(as defined in Section 9(a)), or such limit as permitted by the Board of Directors or a committee thereof pursuant to Section 9(i), because such holder’s shares of Series F Preferred Stock were not redeemed, or were only redeemed in
part then, except as otherwise provided in the Charter, the Company shall redeem the requisite number of shares of Series F Preferred Stock of such holder such that no holder will hold an amount of Series F Preferred Stock in excess of the
applicable ownership limit, subsequent to such redemption. 
 (c) If the Company has given a notice of redemption pursuant to
the Special Optional Redemption Right and has set aside sufficient funds for the redemption in trust for the benefit of the holders of the Series F Preferred Stock called for redemption, then from and after the redemption date, those shares of
Series F Preferred Stock will be treated as no longer being outstanding, no further dividends will accrue and all other rights of the holders of those shares of Series F Preferred Stock will terminate. The holders of those shares of Series F
Preferred Stock will retain their right to receive the redemption price for their shares and any accrued and unpaid dividends to, but not including, the redemption date, without interest. So long as full cumulative dividends on the Series F
Preferred Stock for all past dividend periods shall have been or contemporaneously are (i) declared and paid in cash, or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for payment, nothing herein shall
prevent or restrict the Company’s right or ability to purchase, from time to time, either at a public or a private sale, all or any part of the Series F Preferred Stock at such price or prices as the Company may determine, subject to the
provisions of applicable law, including the repurchase of shares of Series F Preferred Stock in open-market transactions duly authorized by the Board of Directors. 
 (d) The holders of Series F Preferred Stock at the close of business on a Dividend Record Date will be entitled to receive the dividend payable with respect to the Series F Preferred Stock on the
corresponding Dividend Payment Date notwithstanding the redemption of the Series F Preferred Stock pursuant to the Special Optional Redemption Right between such Dividend Record Date and the corresponding Dividend Payment Date or the Company’s
default in the payment of the dividend due. Except as provided herein, the Company shall make no payment or allowance for unpaid dividends, whether or not in arrears, on Series F Preferred Stock for which a notice of redemption pursuant to the
Special Optional Redemption Right has been given. 
 (e) All shares of the Series F Preferred Stock redeemed or repurchased
pursuant to this Section 6, or otherwise acquired in any other manner by the Company, shall be retired and shall be restored to the status of authorized but unissued shares of Preferred Stock, without designation as to series or class.

 Section 7. Voting Rights. 
 (a) Holders of the Series F Preferred Stock shall not have any voting rights, except as set forth in this Section 7. 

  
 7 

 (b) Whenever dividends on any shares of Series F Preferred Stock shall be in arrears for six
or more consecutive or non-consecutive quarterly periods (a “Preferred Dividend Default”), the holders of such Series F Preferred Stock (voting together as a single class with all other
classes or series of preferred stock of the Company upon which like voting rights have been conferred and are exercisable (“Parity Preferred”), including the Series C Cumulative Convertible Preferred Stock, the Series D Cumulative
Convertible Preferred Stock and the Series E Cumulative Redeemable Preferred Stock of the Company) shall be entitled to vote for the election of a total of two additional directors of the Company (the “Preferred Directors”) until
all dividends accumulated on such Series F Preferred Stock and Parity Preferred for the past dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof is set aside for payment. In such case, the entire
Board of Directors will be increased by two directors. 
 (c) The Preferred Directors will be elected by a plurality of the
votes cast in the election for a one-year term and each Preferred Director will serve until his or her successor is duly elected and qualified or until such Preferred Director’s right to hold the office
terminates, whichever occurs earlier, subject to such Preferred Director’s earlier death, disqualification, resignation or removal. The election will take place at (i) either (A) a special meeting called in accordance with
Section 7(d) below if the request is received more than 90 days before the date fixed for the Company’s next annual or special meeting of stockholders or (B) the next annual or special meeting of stockholders if the request is
received within 90 days of the date fixed for the Company’s next annual or special meeting of stockholders, and (ii) at each subsequent annual meeting of stockholders, or special meeting held in place thereof, until all such dividends in
arrears on the Series F Preferred Stock and each such class or series of outstanding Parity Preferred have been paid in full. A dividend in respect of Series F Preferred Stock shall be considered timely made if made within two Business Days after
the applicable Dividend Payment Date if at the time of such late payment date there shall not be any prior quarterly dividend periods in respect of which full dividends were not timely made at the applicable Dividend Payment Date. 

(d) At any time when such voting rights shall have vested, a proper officer of the Company shall call or cause to be called, upon written
request of holders of record of at least 10% of the outstanding shares of Series F Preferred Stock and Parity Preferred, a special meeting of the holders of Series F Preferred Stock and each class or series of Parity Preferred by mailing or causing
to be mailed to such holders a notice of such special meeting to be held not fewer than ten or more than 45 days after the date such notice is given. The record date for determining holders of the Series F Preferred Stock and Parity Preferred
entitled to notice of and to vote at such special meeting will be the close of business on the third Business Day preceding the day on which such notice is mailed. At any such annual or special meeting, all of the holders of the Series F Preferred
Stock and Parity Preferred, by plurality vote, voting together as a single class without regard to class or series will be entitled to elect two directors on the basis of one vote per $25.00 of liquidation preference to which such Series F Preferred
Stock and Parity Preferred are entitled by their terms (excluding amounts in respect of accumulated and unpaid dividends) and not cumulatively. The holder or holders of one-third of the Series F Preferred
Stock and Parity Preferred voting as a single class then outstanding, present in person or by proxy, will constitute a quorum for the election of the Preferred Directors except as otherwise provided by law. Notice of all meetings at which holders of
the Series F Preferred Stock and the Parity Preferred shall be entitled to vote will be given to such holders at their addresses as they appear in the transfer records. At any such meeting or adjournment thereof in the absence of a quorum, subject
to the provisions of any applicable law, a majority of the holders of the Series F Preferred Stock and Parity Preferred voting as a single class present in person or by proxy shall have the power to adjourn the meeting for the election of the
Preferred Directors, without notice other than an announcement at the meeting, until a quorum is present. If a Preferred Dividend Default shall terminate after the notice of a special meeting has been given but before such special meeting has been
held, the Company shall, as soon as practicable after such termination, mail or cause to be mailed notice of such termination to holders of the Series F Preferred Stock and the Parity Preferred that would have been entitled to vote at such special
meeting. 
 (e) If and when all accumulated dividends on such Series F Preferred Stock and all classes or series of Parity
Preferred for the past dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof is set aside for payment, the right of the holders of Series F Preferred Stock and the Parity Preferred to elect such
additional two directors shall immediately cease (subject to revesting in the event of each and every Preferred Dividend Default), and the term of office of each Preferred Director so elected shall terminate and the

  
 8 

 
entire Board of Directors shall be reduced accordingly. Any Preferred Director may be removed at any time with or without cause by the vote of, and shall not be removed otherwise than by the vote
of, the holders of record of a majority of the outstanding Series F Preferred Stock and the Parity Preferred entitled to vote thereon when they have the voting rights set forth in Section 7(b) (voting as a single class). So long as a Preferred
Dividend Default shall continue, any vacancy in the office of a Preferred Director may be filled by written consent of the Preferred Director remaining in office, or if none remains in office, by a vote of the holders of record of a majority of the
outstanding Series F Preferred Stock when they have the voting rights described above (voting as a single class with all other classes or series of Parity Preferred). Each of the Preferred Directors shall be entitled to one vote on any matter.

 (f) So long as any shares of Series F Preferred Stock remain outstanding, the affirmative vote or consent of the holders of two-thirds of the shares of Series F Preferred Stock and each other class or series of preferred stock ranking on parity with the Series F Preferred Stock with respect to the payment of dividends and the
distribution of assets upon liquidation, dissolution or winding up of the Company upon which like voting rights have been conferred outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting as a single class)
will be required to: (i) authorize, create or issue, or increase the number of authorized or issued shares of, any class or series of capital stock ranking senior to the Series F Preferred Stock with respect to payment of dividends or the
distribution of assets upon liquidation, dissolution or winding up of the Company or reclassify any authorized shares of capital stock of the Company into such capital stock, or create, authorize or issue any obligation or security convertible into
or evidencing the right to purchase any such capital stock; or (ii) amend, alter or repeal the provisions of the Charter or the terms of the Series F Preferred Stock, whether by merger, consolidation, transfer or conveyance of all or
substantially all of its assets or otherwise (an “Event”), so as to materially and adversely affect any right, preference, privilege or voting power of the Series F Preferred Stock; provided however, with respect to
the occurrence of any of the Events set forth in (ii) above, so long as the Series F Preferred Stock remains outstanding with the terms thereof materially unchanged, taking into account that, upon the occurrence of an Event, the Company may not
be the surviving entity, the occurrence of such Event shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting power of Series F Preferred Stock, and in such case such holders shall not have any voting
rights with respect to the occurrence of any of the Events set forth in (ii) above. In addition, if the holders of the Series F Preferred Stock receive the greater of the full trading price of the Series F Preferred Stock on the date of an
Event set forth in (ii) above or the $25.00 liquidation preference per share of the Series F Preferred Stock pursuant to the occurrence of any of the Events set forth in (ii) above, then such holders shall not have any voting rights with
respect to the Events set forth in (ii) above. Holders of shares of Series F Preferred Stock shall not be entitled to vote with respect to (A) any increase in the total number of authorized shares of Common Stock or Preferred Stock of the
Company, or (B) any increase in the number of authorized shares of Series F Preferred Stock or the creation or issuance of any other class or series of capital stock, or (C) any increase in the number of authorized shares of any other
class or series of capital stock, in each case referred to in clause (A), (B) or (C) above ranking on parity with or junior to the Series F Preferred Stock with respect to the payment of dividends and the distribution of assets upon
liquidation, dissolution or winding up of the Company. Except as set forth herein, holders of the Series F Preferred Stock shall not have any voting rights with respect to, and the consent of the holders of the Series F Preferred Stock shall not be
required for, the taking of any corporate action, including an Event, regardless of the effect that such corporate action or Event may have upon the powers, preferences, voting power or other rights or privileges of the Series F Preferred Stock.

 (g) The foregoing voting provisions of this Section 7 shall not apply if, at or prior to the time when the act with
respect to which such vote would otherwise be required shall be effected, all outstanding shares of Series F Preferred Stock shall have been redeemed or called for redemption upon proper notice and sufficient funds, in cash, shall have been
deposited in trust to effect such redemption. 
 (h) In any matter in which the Series F Preferred Stock may vote (as expressly
provided herein), each share of Series F Preferred Stock shall be entitled to one vote per $25.00 of liquidation preference. 

Section 8. Conversion. The shares of Series F Preferred Stock are not convertible into or exchangeable for any other property or
securities of the Company, except as provided in this Section 8. 
 (a) Upon the occurrence of a Change of Control, each
holder of shares of Series F Preferred Stock shall 

  
 9 

 
have the right, unless, prior to the Change of Control Conversion Date, the Company has provided or provides notice of its election to redeem the Series F Preferred Stock pursuant to the
Redemption Right or Special Optional Redemption Right, to convert some or all of the Series F Preferred Stock held by such holder (the “Change of Control Conversion Right”) on the Change of Control Conversion Date into a number of
shares of Common Stock, per share of Series F Preferred Stock to be converted (the “Common Stock Conversion Consideration”) equal to the lesser of (A) the quotient obtained by dividing (i) the sum of (x) the $25.00
liquidation preference per share of Series F Preferred Stock to be converted plus (y) the amount of any accrued and unpaid dividends to, but not including, the Change of Control Conversion Date (unless the Change of Control Conversion Date is
after a Dividend Record Date and prior to the corresponding Dividend Payment Date, in which case no additional amount for such accrued and unpaid dividends will be included in such sum) by (ii) the Common Stock Price (as defined herein) and
(B) 0.6843 (the “Share Cap”), subject to the immediately succeeding paragraph. 
 The Share Cap is subject
to pro rata adjustments for any share splits (including those effected pursuant to a distribution of the Common Stock), subdivisions or combinations (in each case, a “Share Split”) with respect to the Common Stock as follows: the
adjusted Share Cap as the result of a Share Split shall be the number of shares of Common Stock that is equivalent to the product obtained by multiplying (i) the Share Cap in effect immediately prior to such Share Split by (ii) a fraction,
the numerator of which is the number of shares of Common Stock outstanding after giving effect to such Share Split and the denominator of which is the number of shares of Common Stock outstanding immediately prior to such Share Split. 

For the avoidance of doubt, subject to the immediately succeeding sentence, the aggregate number of shares of Common Stock (or equivalent
Alternative Conversion Consideration (as defined below), as applicable) issuable in connection with the exercise of the Change of Control Conversion Right shall not exceed 4,790,100 shares of Common Stock (or equivalent Alternative Conversion
Consideration, as applicable), subject to increase to the extent the underwriters’ over-allotment option to purchase additional shares of Series F Preferred Stock in the initial public offering of Series F Preferred Stock is exercised, not to
exceed 5,508,615 shares of Common Stock in total (or equivalent Alternative Conversion Consideration, as applicable) (the “Exchange Cap”). The Exchange Cap is subject to pro rata adjustments for any Share Splits on the same basis as
the corresponding adjustment to the Share Cap. 
 In the case of a Change of Control pursuant to which shares of Common Stock
shall be converted into cash, securities or other property or assets (including any combination thereof) (the “Alternative Form Consideration”), a holder of shares of Series F Preferred Stock shall receive upon conversion of such
shares of Series F Preferred Stock the kind and amount of Alternative Form Consideration which such holder would have owned or been entitled to receive upon the Change of Control had such holder held a number of shares of Common Stock equal to the
Common Stock Conversion Consideration immediately prior to the effective time of the Change of Control (the “Alternative Conversion Consideration”; and the Common Stock Conversion Consideration or the Alternative Conversion
Consideration, as may be applicable to a Change of Control, shall be referred to herein as the “Conversion Consideration”). 
 In the event that holders of Common Stock have the opportunity to elect the form of consideration to be received in the Change of Control, the Conversion Consideration will be deemed to be the kind and
amount of consideration actually received by holders of a majority of the Common Stock that voted for such an election (if electing between two types of consideration) or holders of a plurality of the Common Stock that voted for such an election (if
electing between more than two types of consideration), as the case may be, and will be subject to any limitations to which all holders of Common Stock are subject, including, without limitation, pro rata reductions applicable to any portion of the
consideration payable in the Change of Control. 
 The “Change of Control Conversion Date” shall be a Business
Day set forth in the notice of Change of Control provided in accordance with Section 8(c) below that is no less than 20 days nor more than 35 days after the date on which the Company provides such notice pursuant to Section 8(c).

 The “Common Stock Price” shall be (i) if the consideration to be received in the Change of Control by
the holders of Common Stock is solely cash, the amount of cash consideration per share of Common 

  
 10 

 
Stock or (ii) if the consideration to be received in the Change of Control by holders of Common Stock is other than solely cash (x) the average of the closing sale prices per share of
Common Stock (or, if no closing sale price is reported, the average of the closing bid and ask prices or, if more than one in either case, the average of the average closing bid and the average closing ask prices) for the ten consecutive trading
days immediately preceding, but not including, the effective date of the Change of Control as reported on the principal U.S. securities exchange on which the Common Stock is then traded, or (y) the average of the last quoted bid prices for the
Common Stock in the over-the-counter market as reported by Pink Sheets LLC or similar organization for the ten consecutive trading days immediately preceding, but not
including, the effective date of the Change of Control, if the Common Stock is not then listed for trading on a U.S. securities exchange. 
 (b) No fractional shares of Common Stock shall be issued upon the conversion of Series F Preferred Stock. In lieu of fractional shares, holders shall be entitled to receive the cash value of such
fractional shares based on the Common Stock Price. 
 (c) Within 15 days following the occurrence of a Change of Control, a
notice of occurrence of the Change of Control, describing the resulting Change of Control Conversion Right, shall be delivered to the holders of record of the shares of Series F Preferred Stock at their addresses as they appear on the Company’s
share transfer records and notice shall be provided to the Company’s transfer agent. No failure to give such notice or any defect thereto or in the mailing thereof shall affect the validity of the proceedings for the conversion of any share of
Series F Preferred Stock except as to the holder to whom notice was defective or not given. Each notice shall state: (i) the events constituting the Change of Control; (ii) the date of the Change of Control; (iii) the last date on
which the holders of Series F Preferred Stock may exercise their Change of Control Conversion Right; (iv) the method and period for calculating the Common Stock Price; (v) the Change of Control Conversion Date, which shall be a Business
Day occurring within 20 to 35 days following the date of such notice; (vi) that if, prior to the Change of Control Conversion Date, the Company has provided or provides notice of its election to redeem all or any portion of the Series F
Preferred Stock, the holder will not be able to convert shares of Series F Preferred Stock designated for redemption and such shares of Series F Preferred Stock shall be redeemed on the related redemption date, even if they have already been
tendered for conversion pursuant to the Change of Control Conversion Right; (vii) if applicable, the type and amount of Alternative Conversion Consideration entitled to be received per share of Series F Preferred Stock; (viii) the name and
address of the paying agent and the conversion agent; and (ix) the procedures that the holders of Series F Preferred Stock must follow to exercise the Change of Control Conversion Right. 

(d) The Company shall issue a press release for publication on the Dow Jones & Company, Inc., Business Wire, PR Newswire 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),
or post notice on the Company’s website, in any event prior to the opening of business on the first Business Day following any date on which the Company provides notice pursuant to Section 8(c) above to the holders of Series F Preferred
Stock. 
 (e) In order to exercise the Change of Control Conversion Right, a holder of shares of Series F Preferred Stock shall
be required to deliver, on or before the close of business on the Change of Control Conversion Date, the certificates (if any) representing the shares of Series F Preferred Stock to be converted, duly endorsed for transfer, together with a written
conversion notice completed, to the Company’s transfer agent. Such notice shall state: (i) the relevant Change of Control Conversion Date; (ii) the number of shares of Series F Preferred Stock to be converted; and (iii) that the
shares of Series F Preferred Stock are to be converted pursuant to the applicable provisions of these Articles Supplementary. Notwithstanding the foregoing, if the shares of Series F Preferred Stock are held in global form, such notice shall comply
with applicable procedures of The Depository Trust Company (“DTC”). 
 (f) Holders of Series F Preferred Stock
may withdraw any notice of exercise of a Change of Control Conversion Right (in whole or in part) by a written notice of withdrawal delivered to the Company’s transfer agent prior to the close of business on the Business Day prior to the Change
of Control Conversion Date. The notice of withdrawal must state: (i) the number of withdrawn shares of Series F Preferred Stock; (ii) if certificated shares of Series F Preferred Stock have been issued, the certificate numbers of the
shares of withdrawn Series F Preferred 

  
 11 

 
Stock; and (iii) the number of shares of Series F Preferred Stock, if any, which remain subject to the conversion notice. Notwithstanding the foregoing, if the shares of Series F Preferred
Stock are held in global form, the notice of withdrawal shall comply with applicable procedures of DTC. 
 (g) Shares of Series
F Preferred Stock as to which the Change of Control Conversion Right has been properly exercised and for which the conversion notice has not been properly withdrawn shall be converted into the applicable Conversion Consideration in accordance with
the Change of Control Conversion Right on the Change of Control Conversion Date, unless, prior to the Change of Control Conversion Date, the Company has provided or provides notice of its election to redeem such shares of Series F Preferred Stock,
whether pursuant to its Redemption Right or Special Optional Redemption Right. If the Company elects to redeem shares of Series F Preferred Stock that would otherwise be converted into the applicable Conversion Consideration on a Change of Control
Conversion Date, such shares of Series F Preferred Stock shall not be so converted and the holders of such shares shall be entitled to receive on the applicable redemption date $25.00 per share, plus any accrued and unpaid dividends thereon to, but
not including, the redemption date. 
 (h) The Company shall deliver the applicable Conversion Consideration no later than the
third Business Day following the Change of Control Conversion Date. 
 (i) Notwithstanding anything to the contrary contained
herein, no holder of shares of Series F Preferred Stock will be entitled to convert such shares of Series F Preferred Stock into shares of Common Stock to the extent that receipt of such shares of Common Stock would cause the holder of such shares
of Common Stock (or any other person) to have actual ownership, Beneficial Ownership or Constructive Ownership (each as defined in Section 9(a)) in excess of the Ownership Limit (as defined in Section 9(a)), the Aggregate Stock Ownership
Limit (as defined in Section 9(a)), or such other limit as permitted by the Board of Directors or the Committee pursuant to Section 9(i).

rights shall be exercised for the exclusive benefit of the Charitable Beneficiary. Any dividend or distribution paid to or on behalf of the Purported Record Transferee or Purported Beneficial Transferee prior to the discovery by the Company that
shares of Series F Preferred Stock have been transferred to the Trustee shall be paid to the Trustee upon demand, and any dividend or distribution declared but unpaid shall be paid when due to the Trustee with respect to such Series F Preferred
Stock. Any dividends or distributions so paid over to the Trustee shall be held in trust for the Charitable Beneficiary. The Purported Record Transferee and Purported Beneficial Transferee shall have no voting rights with respect to the Series F
Preferred Stock held in the Trust and, subject to Maryland law, effective as of the date the Series F Preferred Stock has been transferred to the Trustee, the Trustee shall have the authority (at the Trustee’s sole discretion) (A) to
rescind as void any vote cast by a Purported Record Transferee with respect to such Series F Preferred Stock prior to the discovery by the Company that the Series F Preferred Stock has been transferred to the Trustee and (B) to recast such vote
in accordance with the desires of the Trustee acting for the benefit of the Charitable Beneficiary; provided, however, that if the Company has already taken irreversible corporate action, then the Trustee shall not have the authority
to rescind and recast such vote. Notwithstanding any other provision of these Articles Supplementary to the contrary, until the Company has received notification that the Series F Preferred Stock has been transferred into a Trust, the Company shall
be entitled to rely on its share transfer and other stockholder records for purposes of preparing lists of stockholders entitled to vote at meetings, determining the validity and authority of proxies and otherwise conducting votes of stockholders.

 (iv) Within twenty (20) days of receiving notice from the Company that shares of Series F Preferred Stock have been
transferred to the Trust, the Trustee of the Trust shall sell the shares of Series F Preferred Stock held in the Trust to a Person, designated by the Trustee, whose ownership of the shares of Series F Preferred Stock will not violate the ownership
limitations set forth in Section 9(b)(i). Upon such sale, the interest of the Charitable Beneficiary in the shares of Series F Preferred Stock sold shall terminate and the Trustee shall distribute the net proceeds of the sale to the Purported
Record Transferee and to the Charitable Beneficiary as provided in this Section 9(c)(iv). The Purported Record Transferee shall receive the lesser of (A) the price paid by the Purported Record Transferee for the shares of Series F
Preferred Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Series F Preferred Stock at Market Price, the Market Price of
such shares of Series F Preferred Stock on the day of the event which resulted in the transfer of such shares of Series F Preferred Stock to the Trust) and (B) the price per share received by the Trustee (net of any commissions and other
expenses of sale) from the sale or other disposition of the shares of Series F Preferred Stock held in the Trust. The Trustee may reduce the amount payable to the Purported 

  
 15 

 
Record Transferee by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to
Section 9(c)(iii). Any net sales proceeds in excess of the amount payable to the Purported Record Transferee shall be immediately paid to the Charitable Beneficiary together with any dividends or other distributions thereon. If, prior to the
discovery by the Company that shares of such Series F Preferred Stock have been transferred to the Trustee, such shares of Series F Preferred Stock are sold by a Purported Record Transferee then (1) such shares of Series F Preferred Stock shall
be deemed to have been sold on behalf of the Trust and (2) to the extent that the Purported Record Transferee received an amount for such shares of Series F Preferred Stock that exceeds the amount that such Purported Record Transferee was
entitled to receive pursuant to this Section 9(c)(iv), such excess shall be paid to the Trustee upon demand. 
 (v) Series
F Preferred Stock transferred to the Trustee shall be deemed to have been offered for sale to the Company, or its designee, at a price per share equal to the lesser of (A) the price paid by the Purported Record Transferee for the shares of
Series F Preferred Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Series F Preferred Stock at Market Price, the Market
Price of such shares of Series F Preferred Stock on the day of the event which resulted in the transfer of such shares of Series F Preferred Stock to the Trust) and (B) the Market Price on the date the Company, or its designee, accepts such
offer. The Company may reduce the amount payable to the Purported Record Transferee by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee
pursuant to Section 9(c)(iii). The Company shall have the right to accept such offer until the Trustee has sold the shares of Series F Preferred Stock held in the Trust pursuant to Section 9(c)(iv). Upon such a sale to the Company, the
interest of the Charitable Beneficiary in the shares of Series F Preferred Stock sold shall terminate and the Trustee shall distribute the net proceeds of the sale to the Purported Record Transferee and any dividends or other distributions held by
the Trustee with respect to such Series F Preferred Stock shall thereupon be paid to the Charitable Beneficiary. 
 (vi) By
written notice to the Trustee, the Company shall designate one or more nonprofit organizations to be the Charitable Beneficiary of the interest in the Trust such that the Series F Preferred Stock held in the Trust would not violate the restrictions
set forth in Section 9(b)(i) in the hands of such Charitable Beneficiary. 
 (d) Remedies For Breach. If the Board
of Directors or a committee thereof or other designees if permitted by the MGCL shall at any time determine in good faith that a Transfer or other event has taken place in violation of Section 9(b) of these Articles Supplementary or that a
Person intends to acquire, has attempted to acquire or may acquire beneficial ownership (determined without reference to any rules of attribution), Beneficial Ownership or Constructive Ownership of any shares of Series F Preferred Stock of the
Company in violation of Section 9(b) of these Articles Supplementary, the Board of Directors or the Committee or other designees if permitted by the MGCL shall take such action as it deems advisable to refuse to give effect or to prevent such
Transfer, including, but not limited to, causing the Company to redeem shares of Series F Preferred Stock, refusing to give effect to such Transfer on the books of the Company or instituting proceedings to enjoin such Transfer; provided,
however, that any Transfers (or, in the case of events other than a Transfer, ownership or Constructive Ownership or Beneficial Ownership) in violation of Section 9(b)(i) of these Articles Supplementary, shall automatically result in the
transfer to a Trust as described in Section 9(b)(ii) and any Transfer in violation of Section 9(b)(iii) shall automatically be void ab initio irrespective of any action (or non-action) by the Board
of Directors. 
 (e) Notice of Restricted Transfer. Any Person who acquires or attempts to acquire shares of Series F
Preferred Stock in violation of Section 9(b) of these Articles Supplementary, or any Person who is a Purported Beneficial Transferee such that an automatic transfer to a Trust results under Section 9(b)(ii) of these Articles Supplementary,
shall immediately give written notice to the Company of such event and shall provide to the Company such other information as the Company may request in order to determine the effect, if any, of such Transfer or attempted Transfer on the
Company’s status as a REIT. 
 (f) Owners Required To Provide Information. Prior to the Restriction Termination Date
each Person who is a beneficial owner or Beneficial Owner or Constructive Owner of Series F Preferred Stock and each Person (including the stockholder of record) who is holding Series F Preferred Stock for a beneficial owner or Beneficial Owner or
Constructive Owner shall provide to the Company such information that the Company may request, in good faith, in order to determine the Company’s status as a REIT. 

  
 16 

 (g) Remedies Not Limited. Nothing contained in these Articles Supplementary (but
subject to Section 9(l) of these Articles Supplementary) shall limit the authority of the Board of Directors to take such other action as it deems necessary or advisable to protect the Company and the interests of its stockholders by
preservation of the Company’s status as a REIT. 
 (h) Ambiguity. In the case of an ambiguity in the application of
any of the provisions of this Section 9 of these Articles Supplementary, including any definition contained in Section 9(a), the Board of Directors shall have the power to determine the application of the provisions of this Section 9
with respect to any situation based on the facts known to it (subject, however, to the provisions of Section 9(l) of these Articles Supplementary). In the event Section 9 requires an action by the Board of Directors and these Articles
Supplementary fail to provide specific guidance with respect to such action, the Board of Directors shall have the power to determine the action to be taken so long as such action is not contrary to the provisions of Section 9. Absent a
decision to the contrary by the Board of Directors (which the Board of Directors may make in its sole and absolute discretion), if a Person would have (but for the remedies set forth in Section 9(b)) acquired Beneficial or Constructive
Ownership of Series F Preferred Stock in violation of Section 9(b)(i), such remedies (as applicable) shall apply first to the shares of Series F Preferred Stock which, but for such remedies, would have been actually owned by such Person, and
second to shares of Series F Preferred Stock, which, but for such remedies, would have been Beneficially Owned or Constructively Owned (but not actually owned) by such Person, pro rata among the Persons who actually own such shares of Series F
Preferred Stock based upon the relative number of the shares of Series F Preferred Stock held by each such Person. 
 (i)
Exceptions. 
 (i) Subject to Section 9(b)(i)(C), the Board of Directors, in its sole discretion, may exempt
(prospectively or retroactively) a Person from the limitation on a Person Beneficially Owning shares of Series F Preferred Stock in violation of Section 9(b)(i)(A) if the Board of Directors determines that such exemption will not cause any
Individual’s Beneficial Ownership of shares of Capital Stock to violate the Aggregate Stock Ownership Limit and that such exemption will not cause the Company to fail to qualify as a REIT under the Code. 

(ii) Subject to Section 9(b)(i)(C), the Board of Directors in its sole discretion, may exempt (prospectively or retroactively) a
Person from the limitation on a Person Constructively Owning shares of Series F Preferred Stock in violation of Section 9(b)(i)(B), if the Board of Directors determines that such ownership would not cause the Company to fail to qualify as a
REIT under the Code. 
 (iii) Subject to Section 9(b)(i)(C) and the remainder of this Section 9(i)(iii), the Board of
Directors may from time to time increase or decrease the Ownership Limit; provided, however, that the decreased Ownership Limit will not be effective for any Person whose percentage ownership of Series F Preferred Stock is in excess of
such decreased Ownership Limit until such time as such Person's percentage of Series F Preferred Stock equals or falls below the decreased Ownership Limit, but any further acquisition of Series F Preferred Stock in excess of such percentage
ownership of Series F Preferred Stock will be in violation of the Ownership Limit, and, provided further, that the new Ownership Limit would not allow five or fewer Persons to Beneficially Own more than 49% in value of the outstanding capital stock
of the Company. 
 (iv) In granting a Person an exemption under Section 9(i)(i) or (ii) above, the Board of Directors
may require such Person to make certain representations or undertakings or to agree that any violation or attempted violation of such representations or undertakings (or other action which is contrary to the restrictions contained in
Section 9(b) of these Articles Supplementary) will result in such Series F Preferred Stock being transferred to a Trust in accordance with Section 9(b)(ii) of these Articles Supplementary. In granting any exception pursuant to
Section 9(i)(i) or (ii) of these Articles Supplementary, the Board of Directors may require a ruling from the IRS, or an opinion of counsel, in either case in form and substance satisfactory to the Board of Directors in its sole
discretion, as it may deem necessary or advisable in order to determine or ensure the Company's status as a REIT.

ARTICLES SUPPLEMENTARY 
 10,350,000 SHARES OF 
 5.875% SERIES G CUMULATIVE REDEEMABLE PREFERRED
STOCK 
 April 8, 2013 
 Digital Realty Trust, Inc., a Maryland corporation (the “Company”), hereby certifies to the State Department of Assessments and Taxation of Maryland (the “Department”)
that: 
 FIRST: Pursuant to the authority expressly vested in the Board of Directors of the Company (the “Board
of Directors”) by Article IV of the Articles of Amendment and Restatement of the Company filed with the Department on October 26, 2004 (as amended and supplemented to date and as may be amended and supplemented from time to time, the
“Charter”) and Section 2-105 of the Maryland General Corporation Law (the “MGCL”), the Board of Directors, by resolutions duly adopted on June 22, 2012, has authorized the issuance, classification and
designation of a number of shares of the authorized but unissued preferred stock of the Company, par value $0.01 per share (“Preferred Stock”), as a separate class of Preferred Stock, that, on the date of issue, has a liquidation
value or aggregate offering price of up to $250,000,000 (plus up to an additional 15% to cover any underwriter over-allotment option), and, pursuant to the powers contained in the Fourth Amended and Restated Bylaws (as may be amended from time to
time, the “Bylaws”) of the Company and the MGCL, appointed a committee (the “Committee”) of the Board of Directors and delegated to the Committee, to the fullest extent permitted by the MGCL and the Charter and
Bylaws of the Company, among other things, all powers of the Board of Directors with respect to (i) setting the number of shares of the Preferred Stock to be classified and designated, provided that in no event shall the liquidation value or
aggregate offering price of such shares exceed $250,000,000 (plus up to an additional 15% to cover any underwriter over-allotment option), (ii) choosing the cumulative dividend percentage for the Preferred Stock, (iii) selecting the dates
on which dividends will be paid on the Preferred Stock, (iv) establishing the price per share for the Preferred Stock, (v) authorizing, approving and filing these Articles Supplementary with the Department and (vi) authorizing and
approving all such other actions as the Committee may deem necessary or desirable in connection with the classification, authorization, issuance, offer, and sale of the Preferred Stock. 

SECOND: The Committee has unanimously adopted resolutions classifying and designating the Preferred Stock as a separate class of
Preferred Stock to be known as the “5.875% Series G Cumulative Redeemable Preferred Stock,” setting the preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends and other distributions, transfers,
qualifications, terms and conditions of redemption and other terms and conditions of such 5.875% Series G Cumulative Redeemable Preferred Stock, and authorizing the issuance of up to 9,000,000 (plus up to an additional 15% to cover any underwriter
over-allotment option) shares of 5.875% Series G Cumulative Redeemable Preferred Stock. 
 THIRD: The designation, number
of shares, preferences, rights, voting powers, restrictions, limitations as to dividends and other distributions, qualifications, terms and conditions of redemption and other terms and conditions of the separate class of Preferred Stock of the
Company designated as the 5.875% Series G Cumulative Redeemable Preferred Stock are as follows, which upon any restatement of the Charter shall be made a part of or incorporated by reference into the Charter with any necessary or appropriate changes
to the enumeration or lettering of Sections or subsections thereof: 
 Section 1.    Designation and
Number. A series of Preferred Stock, designated the “5.875% Series G Cumulative Redeemable Preferred Stock” (the “Series G Preferred Stock”), is hereby established. The number of shares of Series G Preferred Stock
shall be 10,350,000. 
 Section 2.    Rank. The Series G Preferred Stock will, with respect to
dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company, rank: (a) senior to all classes or 

 
series of the Company’s common stock, par value $0.01 per share (the “Common Stock”), and all classes or series of capital stock of the Company now or hereafter authorized,
issued or outstanding expressly designated as ranking junior to the Series G Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company; (b) on parity with the Series E
Cumulative Redeemable Preferred Stock, par value $0.01 per share, and the Series F Cumulative Redeemable Preferred Stock, par value $0.01 per share, of the Company and with any class or series of capital stock of the Company expressly designated as
ranking on parity with the Series G Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company; and (c) junior to any class or series of capital stock of the Company
expressly designated as ranking senior to the Series G Preferred Stock as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company. The term “capital stock” does not include
convertible or exchangeable debt securities, which will rank senior to the Series G Preferred Stock prior to conversion or exchange. The Series G Preferred Stock will also rank junior in right of payment to the Company’s existing and future
debt obligations. 
 Section 3.    Dividends. 

(a) Subject to the preferential rights of the holders of any class or series of capital stock of the Company ranking senior to the Series
G Preferred Stock as to dividends, the holders of shares of the Series G Preferred Stock shall be entitled to receive, when, as and if authorized by the Board of Directors and declared by the Company, out of funds legally available for the payment
of dividends, cumulative cash dividends at the rate of 5.875% per annum of the $25.00 liquidation preference per share of the Series G Preferred Stock (equivalent to a fixed annual amount of $1.46875 per share of the Series G Preferred Stock).
Such dividends shall accrue and be cumulative from and including the first date on which any shares of Series G Preferred Stock are issued (the “Original Issue Date”) and shall be payable quarterly in arrears on each Dividend
Payment Date (as defined below), commencing June 28, 2013; provided, however, that if any Dividend Payment Date is not a Business Day (as defined below), then the dividend which would otherwise have been payable on such Dividend
Payment Date may be paid, at the Company’s option, on either the immediately preceding Business Day or the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on
the immediately preceding Business Day, in each case 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. The amount of any dividend payable on the Series G Preferred Stock for any partial Dividend Period (as defined below) shall be prorated and computed on the basis of a 360-day year consisting of twelve 30-day
months. Dividends will be payable to holders of record as they appear in the stockholder records of the Company at the close of business on the applicable Dividend Record Date (as defined below). Notwithstanding any provision to the contrary
contained herein, each outstanding share of Series G Preferred Stock shall be entitled to receive a dividend with respect to any Dividend Record Date equal to the dividend paid with respect to each other share of Series G Preferred Stock that is
outstanding on such date. “Dividend Record Date” shall mean the date designated by the Board of Directors for the payment of dividends that is not more than 35 or fewer than 10 days prior to the applicable Dividend Payment Date.
“Dividend Payment Date” shall mean the last calendar day of each March, June, September and December, commencing on June 28, 2013. “Dividend Period” shall mean the respective periods commencing on and including
the first day of January, April, July and October of each year and ending on and including the day preceding the first day of the next succeeding Dividend Period (other than the initial Dividend Period, which shall commence on the Original Issue
Date and end on and include June 30, 2013, and other than the Dividend Period during which any shares of Series G Preferred Stock shall be redeemed pursuant to Section 5 or Section 6, which shall end on and include the day preceding
the redemption date with respect to the shares of Series G Preferred Stock being redeemed). 
 The term “Business
Day” shall mean each day, other than a Saturday or a Sunday, which is not a day on which banking institutions in New York, New York are authorized or required by law, regulation or executive order to close. 

(b) Notwithstanding anything contained herein to the contrary, dividends on the Series G Preferred Stock shall accrue whether or not the
Company has earnings, whether or not there are funds legally available for the payment of such dividends, and whether or not such dividends are authorized or declared. 

  
 2 

 (c) Except as provided in Section 3(d) below, no dividends shall be declared and paid
or declared and set apart for payment, and no other distribution of cash or other property may be declared and made, directly or indirectly, on or with respect to, any shares of Common Stock or shares of any other class or series of capital stock of
the Company ranking, as to dividends, on parity with or junior to the Series G Preferred Stock (other than a dividend paid in shares of Common Stock or in shares of any other class or series of capital stock ranking junior to the Series G Preferred
Stock as to payment of dividends and the distribution of assets upon the Company’s liquidation, dissolution or winding up) for any period, nor shall any shares of Common Stock or any other shares of any other class or series of capital stock of
the Company ranking, as to payment of dividends and the distribution of assets upon the Company’s liquidation, dissolution or winding up, on parity with or junior to the Series G Preferred Stock be redeemed, purchased or otherwise acquired for
any consideration, nor shall any funds be paid or made available for a sinking fund for the redemption of such shares, and no other distribution of cash or other property may be made, directly or indirectly, on or with respect thereto by the Company
(except by conversion into or exchange for other shares of any class or series of capital stock of the Company ranking junior to the Series G Preferred Stock as to payment of dividends and the distribution of assets upon the Company’s
liquidation, dissolution or winding up, and except for the acquisition of shares made pursuant to the provisions of Article VI of the Charter or Section 9 hereof), unless full cumulative dividends on the Series G Preferred Stock for all past
dividend periods shall have been or contemporaneously are (i) declared and paid in cash or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for such payment. 

(d) When dividends are not paid in full (and a sum sufficient for such full payment is not so set apart) on the Series G Preferred Stock
and the shares of any other class or series of capital stock ranking, as to dividends, on parity with the Series G Preferred Stock, all dividends declared upon the Series G Preferred Stock and each such other class or series of capital stock
ranking, as to dividends, on parity with the Series G Preferred Stock shall be declared pro rata so that the amount of dividends declared per share of Series G Preferred Stock and such other class or series of capital stock shall in all cases bear
to each other the same ratio that accrued dividends per share on the Series G Preferred Stock and such other class or series of capital stock (which shall not include any accrual in respect of unpaid dividends on such other class or series of
capital stock for prior dividend periods if such other class or series of capital stock does not have a cumulative dividend) bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or
payments on the Series G Preferred Stock which may be in arrears. 
 (e) Holders of shares of Series G Preferred Stock shall not
be entitled to any dividend, whether payable in cash, property or shares of capital stock, in excess of full cumulative dividends on the Series G Preferred Stock as provided herein. Any dividend payment made on the Series G Preferred Stock shall
first be credited against the earliest accrued but unpaid dividends due with respect to such shares which remain payable. Accrued but unpaid distributions on the Series G Preferred Stock will accumulate as of the Dividend Payment Date on which they
first become payable. 
 Section 4.    Liquidation Preference. 

(a) Upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, before any distribution or payment shall be
made to holders of shares of Common Stock or any other class or series of capital stock of the Company ranking, as to rights upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, junior to the Series G Preferred
Stock, the holders of shares of Series G Preferred Stock shall be entitled to be paid out of the assets of the Company legally available for distribution to its stockholders, after payment of or provision for the debts and other liabilities of the
Company, a liquidation preference of $25.00 per share, plus an amount equal to any accrued and unpaid dividends (whether or not authorized or declared) to but excluding the date of payment. In the event that, upon such voluntary or involuntary
liquidation, dissolution or winding up, the available assets of the Company are insufficient to pay the full amount of the liquidating distributions on all outstanding shares of Series G Preferred Stock and the corresponding amounts payable on all
shares of other classes or series of capital stock of the Company ranking, as to rights upon the Company’s liquidation, dissolution or winding up, on parity with the Series G Preferred Stock in the distribution of assets, then the holders of
the Series G Preferred Stock and each such other class or series of capital stock ranking, as to rights upon any voluntary or involuntary liquidation, dissolution or winding up, on parity with the Series G Preferred Stock shall share ratably in any
such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled. Written notice of any such voluntary or involuntary liquidation, dissolution or winding up of the Company,
stating the payment date or dates when, and the place or places where, the amounts 

  
 3 

 
distributable in such circumstances shall be payable, shall be given by first class mail, postage pre-paid, not fewer than 30 or more than 60 days prior to the payment date stated therein, to
each record holder of shares of Series G Preferred Stock at the respective addresses of such holders as the same shall appear on the stock transfer records of the Company. After payment of the full amount of the liquidating distributions to which
they are entitled, the holders of Series G Preferred Stock will have no right or claim to any of the remaining assets of the Company. The consolidation or merger of the Company with or into any other corporation, trust or entity, or the voluntary
sale, lease, transfer or conveyance of all or substantially all of the property or business of the Company, shall not be deemed to constitute a liquidation, dissolution or winding up of the Company. 

(b) In determining whether a distribution (other than upon voluntary or involuntary liquidation), by dividend, redemption or other
acquisition of shares of capital stock of the Company or otherwise, is permitted under the MGCL, amounts that would be needed, if the Company were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution
of holders of shares of Series G Preferred Stock shall not be added to the Company’s total liabilities. 

Section 5.    Redemption. 
 (a) Shares of Series G Preferred Stock shall not be redeemable prior to April 9, 2018 except as set forth in Section 6 or to preserve the status of the Company as a REIT (as defined in
Section 9(a)) for United States federal income tax purposes. In addition, the Series G Preferred Stock shall be subject to the provisions of Section 9 pursuant to which Series G Preferred Stock owned by a stockholder in excess of the
Ownership Limit (as defined in Section 9(a)) shall automatically be transferred to a Trust (as defined in Section 9(a)) for the exclusive benefit of a Charitable Beneficiary (as defined in Section 9(a)). 

(b) On and after April 9, 2018, the Company, at its option upon not fewer than 30 or more than 60 days’ written notice, may
redeem the Series G Preferred Stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends (whether or not authorized or declared) thereon up to but not
including the date fixed for redemption, without interest, to the extent the Company has funds legally available therefor (the “Redemption Right”). If fewer than all of the outstanding shares of Series G Preferred Stock are to be
redeemed, the shares of Series G Preferred Stock to be redeemed shall be redeemed pro rata (as nearly as may be practicable without creating fractional shares) by lot or by any other equitable method determined by the Company that will not result in
a violation of the Ownership Limit or the Aggregate Stock Ownership Limit (each as defined in Section 9(a)). If redemption is to be by lot and, as a result, any holder of shares of Series G Preferred Stock would have actual ownership,
Beneficial Ownership or Constructive Ownership (each as defined in Section 9(a)) in excess of the Ownership Limit (as defined in Section 9(a)), the Aggregate Stock Ownership Limit (as defined in Section 9(a)), or such other limit as
permitted by the Board of Directors or the Committee pursuant to Section 9(i), because such holder’s shares of Series G Preferred Stock were not redeemed, or were only redeemed in part, then, except as otherwise provided in the Charter,
the Company shall redeem the requisite number of shares of Series G Preferred Stock of such holder such that no holder will hold an amount of Series G Preferred Stock in excess of the applicable ownership limit, subsequent to such redemption.
Holders of Series G Preferred Stock to be redeemed shall surrender such Series G Preferred Stock at the place, or in accordance with the book entry procedures, designated in such notice and shall be entitled to the redemption price of $25.00 per
share and any accrued and unpaid dividends payable upon such redemption following such surrender. If (i) notice of redemption of any shares of Series G Preferred Stock has been given (in the case of a redemption of the Series G Preferred Stock
other than to preserve the status of the Company as a REIT), (ii) the funds necessary for such redemption have been set aside by the Company in trust for the benefit of the holders of any shares of Series G Preferred Stock so called for
redemption, and (iii) irrevocable instructions have been given to pay the redemption price and all accrued and unpaid dividends, then from and after the redemption date, dividends shall cease to accrue on such shares of Series G Preferred
Stock, such shares of Series G Preferred Stock shall no longer be deemed outstanding, and all rights of the holders of such shares shall terminate, except the right to receive the redemption price plus any accrued and unpaid dividends payable upon
such redemption, without interest. So long as full cumulative dividends on the Series G Preferred Stock for all past dividend periods shall have been or contemporaneously are (i) declared and paid in cash, or (ii) declared and a sum
sufficient for the payment thereof in cash is set apart for payment, nothing herein shall prevent or restrict the Company’s right or ability to purchase, from time to time, either at a public or a private sale, all or any part of the Series G
Preferred Stock at such price or prices as the Company may determine, subject to the provisions of applicable law, including the repurchase of shares of Series G Preferred Stock in open-market transactions duly authorized by the Board of Directors.

  
 4 

 (c) In the event of any redemption of the Series G Preferred Stock in order to preserve the
status of the Company as a REIT for United States federal income tax purposes, such redemption shall be made in accordance with the terms and conditions set forth in this Section 5 of these Articles Supplementary. If the Company calls for
redemption any shares of Series G Preferred Stock pursuant to and in accordance with this Section 5(c), then the redemption price for such shares will be an amount in cash equal to $25.00 per share together with all accrued and unpaid dividends
to but excluding the dated fixed for redemption. 
 (d) Unless full cumulative dividends on the Series G Preferred Stock for all
past dividend periods shall have been or contemporaneously are (i) declared and paid in cash, or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for payment, no shares of Series G Preferred Stock shall be
redeemed pursuant to the Redemption Right or Special Optional Redemption Right (defined below) unless all outstanding shares of Series G Preferred Stock are simultaneously redeemed, and the Company shall not purchase or otherwise acquire directly or
indirectly any shares of Series G Preferred Stock or any class or series of capital stock of the Company ranking, as to payment of dividends and the distribution of assets upon liquidation, dissolution or winding up of the Company, on parity with or
junior to the Series G Preferred Stock (except by conversion into or exchange for shares of capital stock of the Company ranking, as to payment of dividends and the distribution of assets upon liquidation, dissolution or winding up of the Company,
junior to the Series G Preferred Stock); provided, however, that the foregoing shall not prevent the purchase of Series G Preferred Stock, or any other class or series of capital stock of the Company ranking, as to payment of dividends
and the distribution of assets upon liquidation, dissolution or winding up of the Company, on parity with or junior to the Series G Preferred Stock, by the Company in accordance with the terms of Sections 5(c) and 9 of these Articles Supplementary
or otherwise, in order to ensure that the Company remains qualified as a REIT for United States federal income tax purposes, or the purchase or acquisition of Series G Preferred Stock pursuant to a purchase or exchange offer made on the same terms
to holders of all outstanding shares of Series G Preferred Stock. 
 (e) Notice of redemption pursuant to the Redemption Right
will be given by publication in a newspaper of general circulation in the City of New York, such publication to be made once a week for two successive weeks commencing not fewer than 30 or more than 60 days prior to the redemption date. A similar
notice will be mailed by the Company, postage prepaid, not fewer than 30 or more than 60 days prior to the redemption date, addressed to the respective holders of record of the Series G Preferred Stock to be redeemed at their respective addresses as
they appear on the transfer records of the Company. No failure to give or defect in such notice shall affect the validity of the proceedings for the redemption of any Series G Preferred Stock except as to the holder to whom such notice was defective
or not given. In addition to any information required by law or by the applicable rules of any exchange upon which the Series G Preferred Stock may be listed or admitted to trading, each such notice shall state: (i) the redemption date;
(ii) the redemption price; (iii) the number of shares of Series G Preferred Stock to be redeemed; (iv) the place or places where the certificates, if any, representing shares of Series G Preferred Stock are to be surrendered for
payment of the redemption price; (v) procedures for surrendering noncertificated shares of Series G Preferred Stock for payment of the redemption price; (vi) that dividends on the shares of Series G Preferred Stock to be redeemed will
cease to accumulate on such redemption date; and (vii) that payment of the redemption price and any accumulated and unpaid dividends will be made upon presentation and surrender of such Series G Preferred Stock. If fewer than all of the shares
of Series G Preferred Stock held by any holder are to be redeemed, the notice mailed to such holder shall also specify the number of shares of Series G Preferred Stock held by such holder to be redeemed. Notwithstanding anything else to the contrary
in these Articles Supplementary, the Company shall not be required to provide notice to the holder of Series G Preferred Stock in the event such holder’s Series G Preferred Stock is redeemed in accordance with Sections 5(c) and 9 of these
Articles Supplementary to preserve the Company’s status as a REIT. 
 (f) If a redemption date falls after a Dividend
Record Date and on or prior to the corresponding Dividend Payment Date, each holder of Series G Preferred Stock at the close of business of such Dividend Record Date shall be entitled to the dividend payable on such shares on the corresponding
Dividend Payment Date notwithstanding the redemption of such shares on or prior to such Dividend Payment Date, and each holder of Series G Preferred Stock that surrenders its shares on such redemption date will be entitled to the dividends accruing
after the end of the Dividend Period to which such Dividend Payment Date relates up to but excluding the redemption date. Except as provided herein, the Company shall make no payment or allowance for unpaid dividends, whether or not in arrears, on
Series G Preferred Stock for which a notice of redemption has been given. 

  
 5 

 (g) All shares of the Series G Preferred Stock redeemed or repurchased pursuant to this
Section 5, or otherwise acquired in any other manner by the Company, shall be retired and shall be restored to the status of authorized but unissued shares of Preferred Stock, without designation as to series or class. 

(h) The Series G Preferred Stock shall have no stated maturity and shall not be subject to any sinking fund or mandatory redemption;
provided, however, that the Series G Preferred Stock owned by a stockholder in excess of the applicable ownership limit shall be subject to the provisions of this Section 5 and Section 9 of these Articles Supplementary.

 Section 6.    Special Optional Redemption by the Company. 

(a) Upon the occurrence of a Change of Control (as defined below), the Company will have the option upon written notice mailed by the
Company, postage pre-paid, no fewer than 30 nor more than 60 days prior to the redemption date and addressed to the holders of record of shares of the Series G Preferred Stock to be redeemed at their respective addresses as they appear on the share
transfer records of the Company, to redeem shares of the Series G Preferred Stock, in whole or in part within 120 days after the first date on which such Change of Control occurred, for cash at $25.00 per share plus accrued and unpaid dividends, if
any, to, but not including, the redemption date (“Special Optional Redemption Right”). No failure to give such notice or any defect thereto or in the mailing thereof shall affect the validity of the proceedings for the redemption of
any shares of Series G Preferred Stock except as to the holder to whom notice was defective or not given. If, prior to the Change of Control Conversion Date (as defined below), the Company has provided or provides notice of redemption with respect
to the Series G Preferred Stock (whether pursuant to the Redemption Right or the Special Optional Redemption Right), the holders of shares of Series G Preferred Stock will not have the conversion right described below in Section 8. 

A “Change of Control” is when, after the original issuance of the Series G Preferred Stock, the following have occurred
and are continuing: 
 (i) the acquisition by any person, including any syndicate or group deemed to be a “person”
under Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), of beneficial ownership, directly or indirectly, through a purchase, merger or other acquisition transaction or series of
purchases, mergers or other acquisition transactions of stock of the Company entitling that person to exercise more than 50% of the total voting power of all stock of the Company entitled to vote generally in the election of the Company’s
directors (except that such person will be deemed to have beneficial ownership of all securities that such person has the right to acquire, whether such right is currently exercisable or is exercisable only upon the occurrence of a subsequent
condition); and 
 (ii) following the closing of any transaction referred to in (i) above, neither the Company nor the
acquiring or surviving entity has a class of common securities (or American Depositary Receipts representing such securities) listed on the New York Stock Exchange (the “NYSE”), the NYSE MKT LLC (the “NYSE MKT”), or
the NASDAQ Stock Market (“NASDAQ”), or listed or quoted on an exchange or quotation system that is a successor to the NYSE, the NYSE MKT or NASDAQ. 
 (b) In addition to any information required by law or by the applicable rules of any exchange upon which the Series G Preferred Stock may be listed or admitted to trading, such notice shall state:
(i) the redemption date; (ii) the redemption price; (iii) the number of shares of Series G Preferred Stock to be redeemed; (iv) the place or places where the certificates, if any, representing shares of Series G Preferred Stock
are to be surrendered for payment of the redemption price; (v) procedures for surrendering noncertificated shares of Series G Preferred Stock for payment of the redemption price; (vi) that dividends on the shares of Series G Preferred
Stock to be redeemed will cease to accumulate on the redemption date; (vii) that payment of the redemption price and any accumulated and unpaid dividends will be made upon presentation and surrender of such Series G Preferred Stock;
(viii) that the shares of Series G Preferred Stock are being redeemed pursuant to the Special Optional Redemption Right in connection with the occurrence of a Change of Control and a brief description of the transaction or transactions
constituting such Change of Control; and (ix) that holders of the shares of Series G Preferred Stock to which the notice relates will not be able to tender such shares of Series G Preferred Stock for conversion in connection

  
 6 

 
with the Change of Control and each share of Series G Preferred Stock tendered for conversion that is selected, prior to the Change of Control Conversion Date, for redemption will be redeemed on
the related redemption date instead of converted on the Change of Control Conversion Date. If fewer than all of the shares of Series G Preferred Stock held by any holder are to be redeemed, the notice mailed to such holder shall also specify the
number of shares of Series G Preferred Stock held by such holder to be redeemed. 
 If fewer than all of the outstanding shares
of Series G Preferred Stock are to be redeemed pursuant to the Special Optional Redemption Right, the shares to be redeemed shall be selected pro rata (as nearly as practicable without creating fractional shares) by lot or in such other equitable
method determined by the Company that will not result in a violation of the Ownership Limit or the Aggregate Stock Ownership Limit (each as defined in Section 9(a)). If such redemption pursuant to the Special Optional Redemption Right is to be
by lot and, as a result, any holder of shares of Series G Preferred Stock would have actual ownership, Beneficial Ownership or Constructive Ownership (each as defined in Section 9(a)) in excess of the Ownership Limit (as defined in
Section 9(a)), the Aggregate Stock Ownership Limit (as defined in Section 9(a)), or such limit as permitted by the Board of Directors or a committee thereof pursuant to Section 9(i), because such holder’s shares of Series G
Preferred Stock were not redeemed, or were only redeemed in part then, except as otherwise provided in the Charter, the Company shall redeem the requisite number of shares of Series G Preferred Stock of such holder such that no holder will hold
an amount of Series G Preferred Stock in excess of the applicable ownership limit, subsequent to such redemption. 
 (c) If the
Company has given a notice of redemption pursuant to the Special Optional Redemption Right and has set aside sufficient funds for the redemption in trust for the benefit of the holders of the Series G Preferred Stock called for redemption, then from
and after the redemption date, those shares of Series G Preferred Stock will be treated as no longer being outstanding, no further dividends will accrue and all other rights of the holders of those shares of Series G Preferred Stock will terminate.
The holders of those shares of Series G Preferred Stock will retain their right to receive the redemption price for their shares and any accrued and unpaid dividends to, but not including, the redemption date, without interest. So long as full
cumulative dividends on the Series G Preferred Stock for all past dividend periods shall have been or contemporaneously are (i) declared and paid in cash, or (ii) declared and a sum sufficient for the payment thereof in cash is set
apart for payment, nothing herein shall prevent or restrict the Company’s right or ability to purchase, from time to time, either at a public or a private sale, all or any part of the Series G Preferred Stock at such price or prices as the
Company may determine, subject to the provisions of applicable law, including the repurchase of shares of Series G Preferred Stock in open-market transactions duly authorized by the Board of Directors. 

(d) The holders of Series G Preferred Stock at the close of business on a Dividend Record Date will be entitled to receive the dividend
payable with respect to the Series G Preferred Stock on the corresponding Dividend Payment Date notwithstanding the redemption of the Series G Preferred Stock pursuant to the Special Optional Redemption Right between such Dividend Record Date and
the corresponding Dividend Payment Date or the Company’s default in the payment of the dividend due. Except as provided herein, the Company shall make no payment or allowance for unpaid dividends, whether or not in arrears, on Series G
Preferred Stock for which a notice of redemption pursuant to the Special Optional Redemption Right has been given. 
 (e) All
shares of the Series G Preferred Stock redeemed or repurchased pursuant to this Section 6, or otherwise acquired in any other manner by the Company, shall be retired and shall be restored to the status of authorized but unissued shares of
Preferred Stock, without designation as to series or class. 
 Section 7.    Voting Rights.

 (a) Holders of the Series G Preferred Stock shall not have any voting rights, except as set forth in this Section 7.

 (b) Whenever dividends on any shares of Series G Preferred Stock shall be in arrears for six or more consecutive or
non-consecutive quarterly periods (a “Preferred Dividend Default”), the holders of such Series G Preferred Stock (voting separately as a class together with all other classes or series of preferred stock of the Company ranking on
parity with the Series G Preferred Stock with respect to payment of dividends and the distribution of assets upon the Company’s liquidation, dissolution or winding up and upon which like voting rights have been conferred and are exercisable
(“Parity Preferred”), including the Series E Cumulative 

  
 7 

 
Redeemable Preferred Stock and the Series F Cumulative Redeemable Preferred Stock of the Company) shall be entitled to vote for the election of a total of two additional directors of the Company
(the “Preferred Directors”) until all dividends accumulated on such Series G Preferred Stock and Parity Preferred for the past dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof is
set aside for payment. In such case, the entire Board of Directors will be increased by two directors. 
 (c) The Preferred
Directors will be elected by a plurality of the votes cast in the election for a one-year term and each Preferred Director will serve until his or her successor is duly elected and qualified or until such Preferred Director’s right to hold the
office terminates, whichever occurs earlier, subject to such Preferred Director’s earlier death, disqualification, resignation or removal. The election will take place at (i) either (A) a special meeting called in accordance with
Section 7(d) below if the request is received more than 90 days before the date fixed for the Company’s next annual or special meeting of stockholders or (B) the next annual or special meeting of stockholders if the request is
received within 90 days of the date fixed for the Company’s next annual or special meeting of stockholders, and (ii) at each subsequent annual meeting of stockholders, or special meeting held in place thereof, until all such dividends in
arrears on the Series G Preferred Stock and each such class or series of outstanding Parity Preferred have been paid in full. A dividend in respect of Series G Preferred Stock shall be considered timely made if made within two Business Days after
the applicable Dividend Payment Date if at the time of such late payment date there shall not be any prior quarterly dividend periods in respect of which full dividends were not timely made at the applicable Dividend Payment Date. 

(d) At any time when such voting rights shall have vested, a proper officer of the Company shall call or cause to be called, upon written
request of holders of record of at least 10% of the outstanding shares of Series G Preferred Stock and Parity Preferred, a special meeting of the holders of Series G Preferred Stock and each class or series of Parity Preferred by mailing or causing
to be mailed to such holders a notice of such special meeting to be held not fewer than ten or more than 45 days after the date such notice is given. The record date for determining holders of the Series G Preferred Stock and Parity Preferred
entitled to notice of and to vote at such special meeting will be the close of business on the third Business Day preceding the day on which such notice is mailed. At any such annual or special meeting, all of the holders of the Series G Preferred
Stock and Parity Preferred, by plurality vote, voting together as a single class without regard to class or series will be entitled to elect two directors on the basis of one vote per $25.00 of liquidation preference to which such Series G Preferred
Stock and Parity Preferred are entitled by their terms (excluding amounts in respect of accumulated and unpaid dividends) and not cumulatively. The holder or holders of one-third of the Series G Preferred Stock and Parity Preferred voting as a
single class then outstanding, present in person or by proxy, will constitute a quorum for the election of the Preferred Directors except as otherwise provided by law. Notice of all meetings at which holders of the Series G Preferred Stock and the
Parity Preferred shall be entitled to vote will be given to such holders at their addresses as they appear in the transfer records. At any such meeting or adjournment thereof in the absence of a quorum, subject to the provisions of any applicable
law, a majority of the holders of the Series G Preferred Stock and Parity Preferred voting as a single class present in person or by proxy shall have the power to adjourn the meeting for the election of the Preferred Directors, without notice other
than an announcement at the meeting, until a quorum is present. If a Preferred Dividend Default shall terminate after the notice of a special meeting has been given but before such special meeting has been held, the Company shall, as soon as
practicable after such termination, mail or cause to be mailed notice of such termination to holders of the Series G Preferred Stock and the Parity Preferred that would have been entitled to vote at such special meeting. 

(e) If and when all accumulated dividends on such Series G Preferred Stock and all classes or series of Parity Preferred for the past
dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof is set aside for payment, the right of the holders of Series G Preferred Stock and the Parity Preferred to elect such additional two directors shall
immediately cease (subject to revesting in the event of each and every Preferred Dividend Default), and the term of office of each Preferred Director so elected shall terminate and the entire Board of Directors shall be reduced accordingly. Any
Preferred Director may be removed at any time with or without cause by the vote of, and shall not be removed otherwise than by the vote of, the holders of record of a majority of the outstanding Series G Preferred Stock and the Parity Preferred
entitled to vote thereon when they have the voting rights set forth in Section 7(b) (voting as a single class). So long as a Preferred Dividend Default shall continue, any vacancy in the office of a Preferred Director may be filled by written
consent of the Preferred Director remaining in office, or if none remains in office, by a vote of the holders of record of a majority of the outstanding Series G Preferred Stock when they have the voting rights described above (voting as a single
class with all other classes or series of Parity Preferred). Each of the Preferred Directors shall be entitled to one vote on any matter. 

  
 8 

 (f) So long as any shares of Series G Preferred Stock remain outstanding, the affirmative
vote or consent of the holders of two-thirds of the shares of Series G Preferred Stock and each other class or series of Parity Preferred outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting together as a
single class) will be required to: (i) authorize, create or issue, or increase the number of authorized or issued shares of, any class or series of capital stock ranking senior to the Series G Preferred Stock with respect to payment of
dividends or the distribution of assets upon liquidation, dissolution or winding up of the Company (collectively, “Senior Capital Stock”) or reclassify any authorized shares of capital stock of the Company into such capital stock,
or create, authorize or issue any obligation or security convertible into or evidencing the right to purchase any such Senior Capital Stock; or (ii) amend, alter or repeal the provisions of the Charter, including the terms of the Series G
Preferred Stock, whether by merger, consolidation, transfer or conveyance of all or substantially all of its assets or otherwise (an “Event”), so as to materially and adversely affect any right, preference, privilege or voting power
of the Series G Preferred Stock; provided however, with respect to the occurrence of any of the Events set forth in (ii) above, so long as the Series G Preferred Stock remains outstanding with the terms thereof materially unchanged,
taking into account that, upon the occurrence of an Event, the Company may not be the surviving entity, the occurrence of such Event shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting power of
Series G Preferred Stock, and in such case such holders shall not have any voting rights with respect to the occurrence of any of the Events set forth in (ii) above. In addition, if the holders of the Series G Preferred Stock receive the
greater of the full trading price of the Series G Preferred Stock on the date of an Event set forth in (ii) above or the $25.00 liquidation preference per share of the Series G Preferred Stock pursuant to the occurrence of any of the Events set
forth in (ii) above, then such holders shall not have any voting rights with respect to the Events set forth in (ii) above. If any Event set forth in (ii) above would materially and adversely affect the rights, preferences, privileges
or voting powers of the Series G Preferred Stock disproportionately relative to other classes or series of Parity Preferred, the affirmative vote of the holders of at least two-thirds of the outstanding shares of the Series G Preferred Stock,
voting separately as a class, will also be required. Holders of shares of Series G Preferred Stock shall not be entitled to vote with respect to (A) any increase in the total number of authorized shares of Common Stock or Preferred Stock of the
Company, or (B) any increase in the number of authorized shares of Series G Preferred Stock or the creation or issuance of any other class or series of capital stock, or (C) any increase in the number of authorized shares of any other
class or series of capital stock, in each case referred to in clause (A), (B) or (C) above ranking on parity with or junior to the Series G Preferred Stock with respect to the payment of dividends and the distribution of assets upon
liquidation, dissolution or winding up of the Company. Except as set forth herein, holders of the Series G Preferred Stock shall not have any voting rights with respect to, and the consent of the holders of the Series G Preferred Stock shall not be
required for, the taking of any corporate action, including an Event, regardless of the effect that such corporate action or Event may have upon the powers, preferences, voting power or other rights or privileges of the Series G Preferred
Stock. 
 (g) The foregoing voting provisions of this Section 7 shall not apply if, at or prior to the time when the act
with respect to which such vote would otherwise be required shall be effected, all outstanding shares of Series G Preferred Stock shall have been redeemed or called for redemption upon proper notice pursuant to these Articles Supplementary, and
sufficient funds, in cash, shall have been deposited in trust to effect such redemption. 
 (h) In any matter in which the
Series G Preferred Stock may vote (as expressly provided herein), each share of Series G Preferred Stock shall be entitled to one vote per $25.00 of liquidation preference. 
 Section 8.    Conversion. The shares of Series G Preferred Stock are not convertible into or exchangeable for any other property or securities of the Company, except as
provided in this Section 8. 
 (a) Upon the occurrence of a Change of Control, each holder of shares of Series G Preferred
Stock shall have the right, unless, prior to the Change of Control Conversion Date, the Company has provided or provides notice of its election to redeem the Series G Preferred Stock pursuant to the Redemption Right or Special Optional
Redemption Right, to convert some or all of the Series G Preferred Stock held by such holder (the “Change of Control Conversion Right”) on the Change of Control Conversion Date into a number of shares of Common Stock, per share
of Series G Preferred Stock to be converted (the “Common Stock Conversion Consideration”) equal to the lesser of (A) the quotient obtained by dividing (i) the sum of (x) the $25.00 liquidation preference per share of

  
 9 

 
Series G Preferred Stock to be converted plus (y) the amount of any accrued and unpaid dividends to, but not including, the Change of Control Conversion Date (unless the Change of Control
Conversion Date is after a Dividend Record Date and prior to the corresponding Dividend Payment Date, in which case no additional amount for such accrued and unpaid dividends will be included in such sum) by (ii) the Common Stock Price (as
defined herein) and (B) 0.7532 (the “Share Cap”), subject to the immediately succeeding paragraph. 
 The
Share Cap is subject to pro rata adjustments for any share splits (including those effected pursuant to a distribution of the Common Stock), subdivisions or combinations (in each case, a “Share Split”) with respect to the Common
Stock as follows: the adjusted Share Cap as the result of a Share Split shall be the number of shares of Common Stock that is equivalent to the product obtained by multiplying (i) the Share Cap in effect immediately prior to such Share Split by
(ii) a fraction, the numerator of which is the number of shares of Common Stock outstanding after giving effect to such Share Split and the denominator of which is the number of shares of Common Stock outstanding immediately prior to such Share
Split. 
 For the avoidance of doubt, subject to the immediately succeeding sentence, the aggregate number of shares of Common
Stock (or equivalent Alternative Conversion Consideration (as defined below), as applicable) issuable in connection with the exercise of the Change of Control Conversion Right shall not exceed 6,778,800 shares of Common Stock (or equivalent
Alternative Conversion Consideration, as applicable), subject to increase to the extent the underwriters’ over-allotment option to purchase additional shares of Series G Preferred Stock in the initial public offering of Series G Preferred Stock
is exercised, not to exceed 7,795,620 shares of Common Stock in total (or equivalent Alternative Conversion Consideration, as applicable) (the “Exchange Cap”). The Exchange Cap is subject to pro rata adjustments for any Share Splits
on the same basis as the corresponding adjustment to the Share Cap. 
 In the case of a Change of Control pursuant to which
shares of Common Stock shall be converted into cash, securities or other property or assets (including any combination thereof) (the “Alternative Form Consideration”), a holder of shares of Series G Preferred Stock shall receive
upon conversion of such shares of Series G Preferred Stock the kind and amount of Alternative Form Consideration which such holder would have owned or been entitled to receive upon the Change of Control had such holder held a number of shares of
Common Stock equal to the Common Stock Conversion Consideration immediately prior to the effective time of the Change of Control (the “Alternative Conversion Consideration”; and the Common Stock Conversion Consideration or the
Alternative Conversion Consideration, as may be applicable to a Change of Control, shall be referred to herein as the “Conversion Consideration”). 
 In the event that holders of Common Stock have the opportunity to elect the form of consideration to be received in the Change of Control, the Conversion Consideration will be deemed to be the kind and
amount of consideration actually received by holders of a majority of the Common Stock that voted for such an election (if electing between two types of consideration) or holders of a plurality of the Common Stock that voted for such an election (if
electing between more than two types of consideration), as the case may be, and will be subject to any limitations to which all holders of Common Stock are subject, including, without limitation, pro rata reductions applicable to any portion of the
consideration payable in the Change of Control. 
 The “Change of Control Conversion Date” shall be a Business
Day set forth in the notice of Change of Control provided in accordance with Section 8(c) below that is no less than 20 days nor more than 35 days after the date on which the Company provides such notice pursuant to Section 8(c).

 The “Common Stock Price” shall be (i) if the consideration to be received in the Change of Control by
the holders of Common Stock is solely cash, the amount of cash consideration per share of Common Stock or (ii) if the consideration to be received in the Change of Control by holders of Common Stock is other than solely cash (x) the
average of the closing sale prices per share of Common Stock (or, if no closing sale price is reported, the average of the closing bid and ask prices or, if more than one in either case, the average of the average closing bid and the average closing
ask prices) for the ten consecutive trading days immediately preceding, but not including, the effective date of the Change of Control as reported on the principal U.S. securities exchange on which the Common Stock is then traded, or (y) the
average of the last quoted bid prices for the Common Stock in the over-the-counter market as reported by Pink Sheets LLC or similar organization for the ten consecutive trading days immediately preceding, but not including, the effective date of the
Change of Control, if the Common Stock is not then listed for trading on a U.S. securities exchange. 

  
 10 

 (b) No fractional shares of Common Stock shall be issued upon the conversion of Series G
Preferred Stock. In lieu of fractional shares, holders shall be entitled to receive the cash value of such fractional shares based on the Common Stock Price. 
 (c) Within 15 days following the occurrence of a Change of Control, a notice of occurrence of the Change of Control, describing the resulting Change of Control Conversion Right, shall be delivered to the
holders of record of the shares of Series G Preferred Stock at their addresses as they appear on the Company’s share transfer records and notice shall be provided to the Company’s transfer agent. No failure to give such notice or any
defect thereto or in the mailing thereof shall affect the validity of the proceedings for the conversion of any share of Series G Preferred Stock except as to the holder to whom notice was defective or not given. Each notice shall state:
(i) the events constituting the Change of Control; (ii) the date of the Change of Control; (iii) the last date on which the holders of Series G Preferred Stock may exercise their Change of Control Conversion Right; (iv) the
method and period for calculating the Common Stock Price; (v) the Change of Control Conversion Date, which shall be a Business Day occurring within 20 to 35 days following the date of such notice; (vi) that if, prior to the Change of
Control Conversion Date, the Company has provided or provides notice of its election to redeem all or any portion of the Series G Preferred Stock, the holder will not be able to convert shares of Series G Preferred Stock designated for redemption
and such shares of Series G Preferred Stock shall be redeemed on the related redemption date, even if they have already been tendered for conversion pursuant to the Change of Control Conversion Right; (vii) if applicable, the type and amount of
Alternative Conversion Consideration entitled to be received per share of Series G Preferred Stock; (viii) the name and address of the paying agent and the conversion agent; and (ix) the procedures that the holders of Series G Preferred
Stock must follow to exercise the Change of Control Conversion Right. 
 (d) The Company shall issue a press release for
publication on the Dow Jones & Company, Inc., Business Wire, PR Newswire 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), or post notice on the Company’s website, in any event prior to the opening of business on the first Business Day following any date on which the Company
provides notice pursuant to Section 8(c) above to the holders of Series G Preferred Stock. 
 (e) In order to exercise the
Change of Control Conversion Right, a holder of shares of Series G Preferred Stock shall be required to deliver, on or before the close of business on the Change of Control Conversion Date, the certificates (if any) representing the shares of Series
G Preferred Stock to be converted, duly endorsed for transfer, together with a written conversion notice completed, to the Company’s transfer agent. Such notice shall state: (i) the relevant Change of Control Conversion Date; (ii) the
number of shares of Series G Preferred Stock to be converted; and (iii) that the shares of Series G Preferred Stock are to be converted pursuant to the applicable provisions of these Articles Supplementary. Notwithstanding the foregoing, if the
shares of Series G Preferred Stock are held in global form, such notice shall comply with applicable procedures of The Depository Trust Company (“DTC”). 
 (f) Holders of Series G Preferred Stock may withdraw any notice of exercise of a Change of Control Conversion Right (in whole or in part) by a written notice of withdrawal delivered to the Company’s
transfer agent prior to the close of business on the Business Day prior to the Change of Control Conversion Date. The notice of withdrawal must state: (i) the number of withdrawn shares of Series G Preferred Stock; (ii) if certificated
shares of Series G Preferred Stock have been issued, the certificate numbers of the shares of withdrawn Series G Preferred Stock; and (iii) the number of shares of Series G Preferred Stock, if any, which remain subject to the conversion notice.
Notwithstanding the foregoing, if the shares of Series G Preferred Stock are held in global form, the notice of withdrawal shall comply with applicable procedures of DTC. 
 (g) Shares of Series G Preferred Stock as to which the Change of Control Conversion Right has been properly exercised and for which the conversion notice has not been properly withdrawn shall be converted
into the applicable Conversion Consideration in accordance with the Change of Control Conversion Right on the Change of Control Conversion Date, unless, prior to the Change of Control Conversion Date, the Company has provided or provides notice of
its election to redeem such shares of Series G Preferred Stock, whether pursuant to its 

  
 11 

 
Redemption Right or Special Optional Redemption Right. If the Company elects to redeem shares of Series G Preferred Stock that would otherwise be converted into the applicable Conversion
Consideration on a Change of Control Conversion Date, such shares of Series G Preferred Stock shall not be so converted and the holders of such shares shall be entitled to receive on the applicable redemption date $25.00 per share, plus any accrued
and unpaid dividends thereon to, but not including, the redemption date. 
 (h) The Company shall deliver the applicable
Conversion Consideration no later than the third Business Day following the Change of Control Conversion Date. 
 (i)
Notwithstanding anything to the contrary contained herein, no holder of shares of Series G Preferred Stock will be entitled to convert such shares of Series G Preferred Stock into shares of Common Stock to the extent that receipt of such shares of
Common Stock would cause the holder of such shares of Common Stock (or any other person) to have actual ownership, Beneficial Ownership or Constructive Ownership (each as defined in Section 9(a)) in excess of the Ownership Limit (as defined in
Section 9(a)), the Aggregate Stock Ownership Limit (as defined in Section 9(a)), or such other limit as permitted by the Board of Directors or the Committee pursuant to Section 9(i).

shares of Series G Preferred Stock in excess of the Ownership Limit and (2) no Person shall Beneficially Own shares of Series G Preferred Stock that, taking into account any other Capital Stock Beneficially Owned by such Person, would result in

(ii) If, prior to the Restriction Termination Date, any Transfer or other event occurs that, if effective, would result in any Person
Beneficially or Constructively Owning Series G Preferred Stock in violation of Section 9(b)(i) of these Articles Supplementary, (A) then that number of shares of Series G Preferred Stock that otherwise would cause such Person to violate

business on the Business Day prior to the date of such Transfer or other event, and such Purported Beneficial Transferee shall thereafter have no rights in such shares or (B) if, for any reason, the transfer to the Trust described in clause
(A) of this sentence is not automatically effective as provided therein to prevent any Person from Beneficially or Constructively Owning Series G Preferred Stock in violation of Section 9(b)(i) of these Articles Supplementary, then the
Transfer of that number of shares of Series G Preferred Stock that otherwise would cause any Person to violate Section 9(b)(i) shall be void ab initio, and the Purported Beneficial Transferee shall have no rights in such shares.

 (iii) Subject to Section 9(l) and prior to the Restriction Termination Date, any Transfer of Series G Preferred Stock
that, if effective, would result in the capital stock of the Company being beneficially owned by fewer than 100 Persons (determined without reference to any rules of attribution) shall be void ab initio, and the intended transferee shall

any Purported Beneficial Transferee or any Purported Record Transferee. Each Charitable Beneficiary shall be designated by the Company as provided in Section 9(c)(vi) of these Articles Supplementary.

held in the Trust. 
 (iii) The Trustee shall have all voting rights and rights to dividends with respect to Series G Preferred
Stock held in the Trust, which rights shall be exercised for the exclusive benefit of the Charitable Beneficiary. Any dividend or distribution paid to or on behalf of the Purported Record Transferee or Purported Beneficial Transferee prior to the
discovery by the Company that shares of Series G Preferred Stock have been transferred to the Trustee shall be paid to the Trustee upon demand, and any dividend or distribution declared but unpaid shall be paid when due to the Trustee with respect
to such Series G Preferred Stock. Any dividends or distributions so paid over to the Trustee shall be held in trust for the Charitable Beneficiary. The Purported Record Transferee and Purported Beneficial Transferee shall have no voting rights with
respect to the Series G Preferred Stock held in the Trust and, subject to Maryland law, effective as of the date the Series G Preferred Stock has been transferred to the Trustee, the Trustee shall have the authority (at the Trustee’s sole
discretion) (A) to rescind as void any vote cast by a Purported Record Transferee with respect to such Series G Preferred Stock prior to the discovery by the Company that the Series G Preferred Stock has been transferred to the Trustee and
(B) to recast such vote in accordance with the desires of the Trustee acting for the benefit of the Charitable Beneficiary; provided, however, that if the Company has already taken irreversible corporate action, then the Trustee
shall not have the authority to rescind and recast such vote. Notwithstanding any other provision of these Articles Supplementary to the contrary, until the Company has received notification that the Series G Preferred Stock has been transferred
into a Trust, the Company shall be entitled to rely on its share transfer and other stockholder records for purposes of preparing lists of stockholders entitled to vote at meetings, determining the validity and authority of proxies and otherwise
conducting votes of stockholders. 
 (iv) Within twenty (20) days of receiving notice from the Company that shares of
Series G Preferred Stock have been transferred to the Trust, the Trustee of the Trust shall sell the shares of Series G Preferred Stock held in the Trust to a Person, designated by the Trustee, whose ownership of the shares of Series G Preferred
Stock will not violate the ownership limitations set forth in Section 9(b)(i). Upon such sale, the interest of the Charitable Beneficiary in the shares of Series G Preferred Stock sold shall terminate and the Trustee shall distribute the net
proceeds of the sale to the Purported Record Transferee and to the Charitable Beneficiary as provided in this Section 9(c)(iv). The Purported Record Transferee shall receive the lesser of (A) the price paid by the Purported Record
Transferee for the shares of Series G Preferred Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Series G Preferred Stock
at Market Price, the Market Price of such shares of Series G Preferred Stock on the day of the event which resulted in the transfer of such shares of Series G Preferred Stock to the Trust) and (B) the price per share received by the Trustee
(net of any commissions and other expenses of sale) from the sale or other disposition of the shares of Series G Preferred Stock held in the Trust. The Trustee may reduce the amount payable to the Purported Record Transferee by the amount of
dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 9(c)(iii). Any net sales proceeds in excess of the amount payable to the
Purported Record Transferee shall be immediately paid to the Charitable Beneficiary together with any dividends or other distributions thereon. If, prior to the discovery by the Company that shares of such Series G Preferred Stock have been
transferred to the Trustee, such shares of Series G Preferred Stock are sold by a Purported Record Transferee then (1) such shares of Series G Preferred Stock shall be deemed to have been sold on behalf of the Trust and (2) to the extent
that the Purported Record Transferee received an amount for such shares of Series G Preferred Stock that exceeds the amount that such Purported Record Transferee was entitled to receive pursuant to this Section 9(c)(iv), such excess shall be
paid to the Trustee upon demand. 
 (v) Series G Preferred Stock transferred to the Trustee shall be deemed to have been offered
for sale to the Company, or its designee, at a price per share equal to the lesser of (A) the price paid by the Purported Record Transferee for the shares of Series G Preferred Stock in the transaction that resulted in such transfer to the
Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Series G Preferred Stock at Market Price, the Market Price of such shares of Series G Preferred Stock on the day of the event

  
 15 

 
which resulted in the transfer of such shares of Series G Preferred Stock to the Trust) and (B) the Market Price on the date the Company, or its designee, accepts such offer. The Company may
reduce the amount payable to the Purported Record Transferee by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to
Section 9(c)(iii). The Company shall have the right to accept such offer until the Trustee has sold the shares of Series G Preferred Stock held in the Trust pursuant to Section 9(c)(iv). Upon such a sale to the Company, the interest of the
Charitable Beneficiary in the shares of Series G Preferred Stock sold shall terminate and the Trustee shall distribute the net proceeds of the sale to the Purported Record Transferee and any dividends or other distributions held by the Trustee with
respect to such Series G Preferred Stock shall thereupon be paid to the Charitable Beneficiary. 
 (vi) By written notice to the
Trustee, the Company shall designate one or more nonprofit organizations to be the Charitable Beneficiary of the interest in the Trust such that the Series G Preferred Stock held in the Trust would not violate the restrictions set forth in
Section 9(b)(i) in the hands of such Charitable Beneficiary. 
 (d) Remedies For Breach. If the Board of Directors
or a committee thereof or other designees if permitted by the MGCL shall at any time determine in good faith that a Transfer or other event has taken place in violation of Section 9(b) of these Articles Supplementary or that a Person intends to
acquire, has attempted to acquire or may acquire beneficial ownership (determined without reference to any rules of attribution), Beneficial Ownership or Constructive Ownership of any shares of Series G Preferred Stock of the Company in violation of
Section 9(b) of these Articles Supplementary, the Board of Directors or the Committee or other designees if permitted by the MGCL shall take such action as it deems advisable to refuse to give effect or to prevent such Transfer, including, but
not limited to, causing the Company to redeem shares of Series G Preferred Stock, refusing to give effect to such Transfer on the books of the Company or instituting proceedings to enjoin such Transfer; provided, however, that any
Transfers (or, in the case of events other than a Transfer, ownership or Constructive Ownership or Beneficial Ownership) in violation of Section 9(b)(i) of these Articles Supplementary, shall automatically result in the transfer to a Trust as
described in Section 9(b)(ii) and any Transfer in violation of Section 9(b)(iii) shall automatically be void ab initio irrespective of any action (or non-action) by the Board of Directors. 

(e) Notice of Restricted Transfer. Any Person who acquires or attempts to acquire shares of Series G Preferred Stock in violation
of Section 9(b) of these Articles Supplementary, or any Person who is a Purported Beneficial Transferee such that an automatic transfer to a Trust results under Section 9(b)(ii) of these Articles Supplementary, shall immediately give
written notice to the Company of such event and shall provide to the Company such other information as the Company may request in order to determine the effect, if any, of such Transfer or attempted Transfer on the Company’s status as a REIT.

 (f) Owners Required To Provide Information. Prior to the Restriction Termination Date each Person who is a beneficial
owner or Beneficial Owner or Constructive Owner of Series G Preferred Stock and each Person (including the stockholder of record) who is holding Series G Preferred Stock for a beneficial owner or Beneficial Owner or Constructive Owner shall provide
to the Company such information that the Company may request, in good faith, in order to determine the Company’s status as a REIT. 
 (g) Remedies Not Limited. Nothing contained in these Articles Supplementary (but subject to Section 9(l) of these Articles Supplementary) shall limit the authority of the Board of Directors to
take such other action as it deems necessary or advisable to protect the Company and the interests of its stockholders by preservation of the Company’s status as a REIT. 
 (h) Ambiguity. In the case of an ambiguity in the application of any of the provisions of this Section 9 of these Articles Supplementary, including any definition contained in
Section 9(a), the Board of Directors shall have the power to determine the application of the provisions of this Section 9 with respect to any situation based on the facts known to it (subject, however, to the provisions of
Section 9(l) of these Articles Supplementary). In the event Section 9 requires an action by the Board of Directors and these Articles Supplementary fail to provide specific guidance with respect to such action, the Board of Directors shall
have the power to determine the action to be taken so long as such action is not contrary to the provisions of Section 9. Absent a decision to the contrary by the Board of Directors (which the Board of Directors may make in its sole and
absolute discretion), if a Person would have (but for the remedies set forth in Section 9(b)) acquired Beneficial or Constructive Ownership of Series G Preferred Stock in violation of Section 9(b)(i), such remedies (as applicable) shall
apply first to the shares of Series G 

  
 16 

 
Preferred Stock which, but for such remedies, would have been actually owned by such Person, and second to shares of Series G Preferred Stock, which, but for such remedies, would have been
Beneficially Owned or Constructively Owned (but not actually owned) by such Person, pro rata among the Persons who actually own such shares of Series G Preferred Stock based upon the relative number of the shares of Series G Preferred Stock held by
each such Person. 
 (i) Exceptions. 
 (i) Subject to Section 9(b)(i)(C), the Board of Directors, in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Beneficially Owning shares of
Series G Preferred Stock in violation of Section 9(b)(i)(A) if the Board of Directors determines that such exemption will not cause any Individual’s Beneficial Ownership of shares of Capital Stock to violate the Aggregate Stock Ownership
Limit and that such exemption will not cause the Company to fail to qualify as a REIT under the Code. 
 (ii) Subject to
Section 9(b)(i)(C), the Board of Directors in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Constructively Owning shares of Series G Preferred Stock in violation of
Section 9(b)(i)(B), if the Board of Directors determines that such ownership would not cause the Company to fail to qualify as a REIT under the Code. 
 (iii) Subject to Section 9(b)(i)(C) and the remainder of this Section 9(i)(iii), the Board of Directors may from time to time increase or decrease the Ownership Limit; provided,
however, that the decreased Ownership Limit will not be effective for any Person whose percentage ownership of Series G Preferred Stock is in excess of such decreased Ownership Limit until such time as such Person’s percentage of Series
G Preferred Stock equals or falls below the decreased Ownership Limit, but any further acquisition of Series G Preferred Stock in excess of such percentage ownership of Series G Preferred Stock will be in violation of the Ownership Limit, and,
provided further, that the new Ownership Limit would not allow five or fewer Persons to Beneficially Own more than 49% in value of the outstanding capital stock of the Company. 
 (iv) In granting a Person an exemption under Section 9(i)(i) or (ii) above, the Board of Directors may require such Person to make certain representations or undertakings or to agree that any
violation or attempted violation of such representations or undertakings (or other action which is contrary to the restrictions contained in Section 9(b) of these Articles Supplementary) will result in such Series G Preferred Stock being
transferred to a Trust in accordance with Section 9(b)(ii) of these Articles Supplementary. In granting any exception pursuant to Section 9(i)(i) or (ii) of these Articles Supplementary, the Board of Directors may require a ruling
from the IRS, or an opinion of counsel, in either case in form and substance satisfactory to the Board of Directors in its sole discretion, as it may deem necessary or advisable in order to determine or ensure the Company’s status as a REIT.

ARTICLES SUPPLEMENTARY 
 13,800,000 SHARES OF 
 7.375% SERIES H CUMULATIVE REDEEMABLE PREFERRED
STOCK 
 MARCH 25, 2014 
 Digital Realty Trust, Inc., a Maryland corporation (the “Company”), hereby certifies to the State Department of Assessments and Taxation of Maryland (the “Department”)
that: 
 FIRST: Pursuant to the authority expressly vested in the Board of Directors of the Company (the “Board
of Directors”) by Article IV of the Articles of Amendment and Restatement of the Company filed with the Department on October 26, 2004 (as amended and supplemented to date and as may be amended and supplemented from time to time, the
“Charter”) and Section 2-105 of the Maryland General Corporation Law (the “MGCL”), the Board of Directors, by resolutions duly adopted on May 1, 2013 has authorized the issuance, classification and
designation of a number of shares of the authorized but unissued preferred stock of the Company, par value $0.01 per share (“Preferred Stock”), as a separate class of Preferred Stock, that, on the date of issue, has a liquidation
value or aggregate offering price of up to $400,000,000 (plus up to an additional 15% to cover any underwriter over-allotment option), and, pursuant to the powers contained in the Fourth Amended and Restated Bylaws (as may be amended from time to
time, the “Bylaws”) of the Company and the MGCL, appointed a committee (the “Committee”) of the Board of Directors and delegated to the Committee, to the fullest extent permitted by the MGCL and the Charter and
Bylaws of the Company, among other things, all powers of the Board of Directors with respect to (i) setting the number of shares of the Preferred Stock to be classified and designated, provided that in no event shall the liquidation value or
aggregate offering price of such shares exceed $400,000,000 (plus up to an additional 15% to cover any underwriter over-allotment option), (ii) choosing the cumulative dividend percentage for the Preferred Stock, (iii) selecting the dates
on which dividends will be paid on the Preferred Stock, (iv) establishing the price per share for the Preferred Stock, (v) authorizing, approving and filing these Articles Supplementary with the Department and (vi) authorizing and
approving all such other actions as the Committee may deem necessary or desirable in connection with the classification, authorization, issuance, offer, and sale of the Preferred Stock. 

SECOND: The Committee has unanimously adopted resolutions classifying and designating the Preferred Stock as a separate class of
Preferred Stock to be known as the “7.375% Series H Cumulative Redeemable Preferred Stock,” setting the preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends and other distributions, transfers,
qualifications, terms and conditions of redemption and other terms and conditions of such 7.375% Series H Cumulative Redeemable Preferred Stock, and authorizing the issuance of up to 12,000,000 (plus up to an additional 15% to cover any underwriter
over-allotment option) shares of 7.375% Series H Cumulative Redeemable Preferred Stock. 
 THIRD: The designation, number
of shares, preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends and other distributions, transfers, qualifications, terms and conditions of redemption and other terms and conditions of the separate class
of Preferred Stock of the Company designated as the 7.375% Series H Cumulative Redeemable Preferred Stock are as follows, which upon any restatement of the Charter shall be made a part of or incorporated by reference into the Charter with any
necessary or appropriate changes to the enumeration or lettering of Sections or subsections thereof: 
 Section 1.
Designation and Number. A series of Preferred Stock, designated the “7.375% Series H Cumulative Redeemable Preferred Stock” (the “Series H Preferred Stock”), is hereby established. The number of shares of Series H
Preferred Stock shall be 13,800,000. 

 Section 2. Rank. The Series H Preferred Stock will, with respect to dividend
rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company, rank: (a) senior to all classes or series of the Company’s common stock, par value $0.01 per share (the “Common
Stock”), and all classes or series of capital stock of the Company now or hereafter authorized, issued or outstanding expressly designated as ranking junior to the Series H Preferred Stock as to dividend rights and rights upon voluntary or
involuntary liquidation, dissolution or winding up of the Company; (b) on parity with the Series E Cumulative Redeemable Preferred Stock, par value $0.01 per share, the Series F Cumulative Redeemable Preferred Stock, par value $0.01 per share,
and the Series G Cumulative Redeemable Preferred Stock, par value $0.01 per share, of the Company and with any class or series of capital stock of the Company expressly designated as ranking on parity with the Series H Preferred Stock as to dividend
rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company; and (c) junior to any class or series of capital stock of the Company expressly designated as ranking senior to the Series H Preferred Stock
as to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Company. The term “capital stock” does not include convertible or exchangeable debt securities, which will rank senior to
the Series H Preferred Stock prior to conversion or exchange. The Series H Preferred Stock will also rank junior in right of payment to the Company’s existing and future debt obligations. 

Section 3. Dividends. 
 (a) Subject to the preferential rights of the holders of any class or series of capital stock of the Company ranking senior to the Series H Preferred Stock as to dividends, the holders of shares of the
Series H Preferred Stock shall be entitled to receive, when, as and if authorized by the Board of Directors and declared by the Company, out of funds legally available for the payment of dividends, cumulative cash dividends at the rate of
7.375% per annum of the $25.00 liquidation preference per share of the Series H Preferred Stock (equivalent to a fixed annual amount of $1.84375 per share of the Series H Preferred Stock). Such dividends shall accrue and be cumulative from and
including the first date on which any shares of Series H Preferred Stock are issued (the “Original Issue Date”) and shall be payable quarterly in arrears on each Dividend Payment Date (as defined below), commencing June 30,
2014; provided, however, that if any Dividend Payment Date is not a Business Day (as defined below), then the dividend which would otherwise have been payable on such Dividend Payment Date may be paid, at the Company’s option, on
either the immediately preceding Business Day or the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case 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. The amount of any
dividend payable on the Series H Preferred Stock for any partial Dividend Period (as defined below) shall be prorated and computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends will be payable to holders of record as
they appear in the stockholder records of the Company at the close of business on the applicable Dividend Record Date (as defined below). Notwithstanding any provision to the contrary contained herein, each outstanding share of Series H Preferred
Stock shall be entitled to receive a dividend with respect to any Dividend Record Date equal to the dividend paid with respect to each other share of Series H Preferred Stock that is outstanding on such date. “Dividend Record Date”
shall mean the date designated by the Board of Directors for the payment of dividends that is not more than 35 or fewer than 10 days prior to the applicable Dividend Payment Date. “Dividend Payment Date” shall mean the last calendar
day of each March, June, September and December, commencing on June 30, 2014. “Dividend Period” shall mean the respective periods commencing on and including the first day of January, April, July and October of each year and
ending on and including the day preceding the first day of the next succeeding Dividend Period (other than the initial Dividend Period, which shall commence on the Original Issue Date and end on and include June 30, 2014, and other than the
Dividend Period during which any shares of Series H Preferred Stock shall be redeemed pursuant to Section 5 or Section 6, which shall end on and include the day preceding the redemption date with respect to the shares of Series H Preferred
Stock being redeemed). 
 The term “Business Day” shall mean each day, other than a Saturday or a Sunday, which
is not a day on which banking institutions in New York, New York are authorized or required by law, regulation or executive order to close. 
 (b) Notwithstanding anything contained herein to the contrary, dividends on the Series H Preferred Stock shall accrue whether or not the Company has earnings, whether or not there are funds legally
available for the payment of such dividends, and whether or not such dividends are authorized or declared. 

  
 2 

 (c) Except as provided in Section 3(d) below, no dividends shall be declared and paid
or declared and set apart for payment, and no other distribution of cash or other property may be declared and made, directly or indirectly, on or with respect to, any shares of Common Stock or shares of any other class or series of capital stock of
the Company ranking, as to dividends, on parity with or junior to the Series H Preferred Stock (other than a dividend paid in shares of Common Stock or in shares of any other class or series of capital stock ranking junior to the Series H Preferred
Stock as to payment of dividends and the distribution of assets upon the Company’s liquidation, dissolution or winding up) for any period, nor shall any shares of Common Stock or any other shares of any other class or series of capital stock of
the Company ranking, as to payment of dividends and the distribution of assets upon the Company’s liquidation, dissolution or winding up, on parity with or junior to the Series H Preferred Stock be redeemed, purchased or otherwise acquired for
any consideration, nor shall any funds be paid or made available for a sinking fund for the redemption of such shares, and no other distribution of cash or other property may be made, directly or indirectly, on or with respect thereto by the Company
(except by conversion into or exchange for other shares of any class or series of capital stock of the Company ranking junior to the Series H Preferred Stock as to payment of dividends and the distribution of assets upon the Company’s
liquidation, dissolution or winding up, and except for the acquisition of shares made pursuant to the provisions of Article VI of the Charter or Section 9 hereof), unless full cumulative dividends on the Series H Preferred Stock for all past
dividend periods shall have been or contemporaneously are (i) declared and paid in cash or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for such payment. 

(d) When dividends are not paid in full (and a sum sufficient for such full payment is not so set apart) on the Series H Preferred Stock
and the shares of any other class or series of capital stock ranking, as to dividends, on parity with the Series H Preferred Stock, all dividends declared upon the Series H Preferred Stock and each such other class or series of capital stock
ranking, as to dividends, on parity with the Series H Preferred Stock shall be declared pro rata so that the amount of dividends declared per share of Series H Preferred Stock and such other class or series of capital stock shall in all cases bear
to each other the same ratio that accrued dividends per share on the Series H Preferred Stock and such other class or series of capital stock (which shall not include any accrual in respect of unpaid dividends on such other class or series of
capital stock for prior dividend periods if such other class or series of capital stock does not have a cumulative dividend) bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or
payments on the Series H Preferred Stock which may be in arrears. 
 (e) Holders of shares of Series H Preferred Stock shall not
be entitled to any dividend, whether payable in cash, property or shares of capital stock, in excess of full cumulative dividends on the Series H Preferred Stock as provided herein. Any dividend payment made on the Series H Preferred Stock shall
first be credited against the earliest accrued but unpaid dividends due with respect to such shares which remain payable. Accrued but unpaid distributions on the Series H Preferred Stock will accumulate as of the Dividend Payment Date on which they
first become payable. 
 Section 4. Liquidation Preference. 

(a) Upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, before any distribution or payment shall be
made to holders of shares of Common Stock or any other class or series of capital stock of the Company ranking, as to rights upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, junior to the Series H Preferred
Stock, the holders of shares of Series H Preferred Stock shall be entitled to be paid out of the assets of the Company legally available for distribution to its stockholders, after payment of or provision for the debts and other liabilities of the
Company and, subject to compliance with section 7(f)(i) of these Articles Supplementary, any class or series of capital stock of the Company ranking, as to rights upon any voluntary or involuntary liquidation, dissolution or winding up of the
Company, senior to the Series H Preferred Stock, a liquidation preference of $25.00 per share, plus an amount equal to any accrued and unpaid dividends (whether or not authorized or declared) to but excluding the date of payment. In the event that,
upon such voluntary or involuntary liquidation, dissolution or winding up, the available assets of the Company are insufficient to pay the full amount of the liquidating distributions on all outstanding shares of Series H Preferred Stock and the
corresponding amounts payable on all shares of other classes or series of capital stock of the Company ranking, as to rights upon the Company’s liquidation, dissolution or winding up, on parity with the Series H Preferred Stock in

  
 3 

 
the distribution of assets, then the holders of the Series H Preferred Stock and each such other class or series of capital stock ranking, as to rights upon any voluntary or involuntary
liquidation, dissolution or winding up, on parity with the Series H Preferred Stock shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled.
Written notice of any such voluntary or involuntary liquidation, dissolution or winding up of the Company, stating the payment date or dates when, and the place or places where, the amounts distributable in such circumstances shall be payable, shall
be given by first class mail, postage pre-paid, not fewer than 30 or more than 60 days prior to the payment date stated therein, to each record holder of shares of Series H Preferred Stock at the respective addresses of such holders as the same
shall appear on the stock transfer records of the Company. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of Series H Preferred Stock will have no right or claim to any of the remaining
assets of the Company. The consolidation or merger of the Company with or into any other corporation, trust or entity, or the voluntary sale, lease, transfer or conveyance of all or substantially all of the property or business of the Company, shall
not be deemed to constitute a liquidation, dissolution or winding up of the Company. 
 (b) In determining whether a
distribution (other than upon voluntary or involuntary liquidation), by dividend, redemption or other acquisition of shares of capital stock of the Company or otherwise, is permitted under the MGCL, amounts that would be needed, if the Company were
to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of holders of shares of Series H Preferred Stock shall not be added to the Company’s total liabilities. 

Section 5. Redemption. 
 (a) Shares of Series H Preferred Stock shall not be redeemable prior to March 26, 2019 except as set forth in Section 6 or to preserve the status of the Company as a REIT (as defined in
Section 9(a)) for United States federal income tax purposes. In addition, the Series H Preferred Stock shall be subject to the provisions of Section 9 pursuant to which Series H Preferred Stock owned by a stockholder in excess of the
Ownership Limit (as defined in Section 9(a)) shall automatically be transferred to a Trust (as defined in Section 9(a)) for the exclusive benefit of a Charitable Beneficiary (as defined in Section 9(a)). 

(b) On and after March 26, 2019, the Company, at its option upon not fewer than 30 or more than 60 days’ written notice, may
redeem the Series H Preferred Stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends (whether or not authorized or declared) thereon up to but not
including the date fixed for redemption, without interest, to the extent the Company has funds legally available therefor (the “Redemption Right”). If fewer than all of the outstanding shares of Series H Preferred Stock are to be
redeemed, the shares of Series H Preferred Stock to be redeemed shall be redeemed pro rata (as nearly as may be practicable without creating fractional shares) or by lot as determined by the Company. If redemption is to be by lot and, as a result,
any holder of shares of Series H Preferred Stock would have actual ownership, Beneficial Ownership or Constructive Ownership (each as defined in Section 9(a)) in excess of the Ownership Limit (as defined in Section 9(a)), the Aggregate
Stock Ownership Limit (as defined in Section 9(a)), or such other limit as permitted by the Board of Directors or the Committee pursuant to Section 9(i), because such holder’s shares of Series H Preferred Stock were not redeemed, or
were only redeemed in part, then, except as otherwise provided in the Charter, the Company shall redeem the requisite number of shares of Series H Preferred Stock of such holder such that no holder will hold an amount of Series H Preferred Stock in
excess of the applicable ownership limit, subsequent to such redemption. Holders of Series H Preferred Stock to be redeemed shall surrender such Series H Preferred Stock at the place, or in accordance with the book entry procedures, designated in
such notice and shall be entitled to the redemption price of $25.00 per share and any accrued and unpaid dividends payable upon such redemption following such surrender. If (i) notice of redemption of any shares of Series H Preferred Stock has
been given (in the case of a redemption of the Series H Preferred Stock other than to preserve the status of the Company as a REIT), (ii) the funds necessary for such redemption have been set aside by the Company in trust for the benefit of the
holders of any shares of Series H Preferred Stock so called for redemption, and (iii) irrevocable instructions have been given to pay the redemption price and all accrued and unpaid dividends, then from and after the redemption date, dividends
shall cease to accrue on such shares of Series H Preferred Stock, such shares of Series H Preferred Stock shall no longer be deemed outstanding, and all rights of the holders of such shares shall terminate, except the right to receive the redemption
price plus any accrued and unpaid dividends payable upon such redemption, without interest. So long as full cumulative dividends on the Series H Preferred 

  
 4 

 
Stock for all past dividend periods shall have been or contemporaneously are (i) declared and paid in cash, or (ii) declared and a sum sufficient for the payment thereof in cash is set
apart for payment, nothing herein shall prevent or restrict the Company’s right or ability to purchase, from time to time, either at a public or a private sale, all or any part of the Series H Preferred Stock at such price or prices as the
Company may determine, subject to the provisions of applicable law, including the repurchase of shares of Series H Preferred Stock in open-market transactions duly authorized by the Board of Directors. 

(c) In the event of any redemption of the Series H Preferred Stock in order to preserve the status of the Company as a REIT for United
States federal income tax purposes, such redemption shall be made in accordance with the terms and conditions set forth in this Section 5 of these Articles Supplementary. If the Company calls for redemption any shares of Series H Preferred
Stock pursuant to and in accordance with this Section 5(c), then the redemption price for such shares will be an amount in cash equal to $25.00 per share together with all accrued and unpaid dividends to but excluding the dated fixed for
redemption. 
 (d) Unless full cumulative dividends on the Series H Preferred Stock for all past dividend periods shall have
been or contemporaneously are (i) declared and paid in cash, or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for payment, no shares of Series H Preferred Stock shall be redeemed pursuant to the Redemption
Right or Special Optional Redemption Right (defined below) unless all outstanding shares of Series H Preferred Stock are simultaneously redeemed, and the Company shall not purchase or otherwise acquire directly or indirectly any shares of Series H
Preferred Stock or any class or series of capital stock of the Company ranking, as to payment of dividends and the distribution of assets upon liquidation, dissolution or winding up of the Company, on parity with or junior to the Series H Preferred
Stock (except by conversion into or exchange for shares of capital stock of the Company ranking, as to payment of dividends and the distribution of assets upon liquidation, dissolution or winding up of the Company, junior to the Series H Preferred
Stock); provided, however, that the foregoing shall not prevent the purchase of Series H Preferred Stock, or any other class or series of capital stock of the Company ranking, as to payment of dividends and the distribution of assets
upon liquidation, dissolution or winding up of the Company, on parity with or junior to the Series H Preferred Stock, by the Company in accordance with the terms of Sections 5(c) and 9 of these Articles Supplementary or otherwise, in order to ensure
that the Company remains qualified as a REIT for United States federal income tax purposes, or the purchase or acquisition of Series H Preferred Stock pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding
shares of Series H Preferred Stock. 
 (e) Notice of redemption pursuant to the Redemption Right will be given by publication in
a newspaper of general circulation in the City of New York, such publication to be made once a week for two successive weeks commencing not fewer than 30 or more than 60 days prior to the redemption date. A similar notice will be mailed by the
Company, postage prepaid, not fewer than 30 or more than 60 days prior to the redemption date, addressed to the respective holders of record of the Series H Preferred Stock to be redeemed at their respective addresses as they appear on the transfer
records of the Company. No failure to give or defect in such notice shall affect the validity of the proceedings for the redemption of any Series H Preferred Stock except as to the holder to whom such notice was defective or not given. In addition
to any information required by law or by the applicable rules of any exchange upon which the Series H Preferred Stock may be listed or admitted to trading, each such notice shall state: (i) the redemption date; (ii) the redemption price;
(iii) the number of shares of Series H Preferred Stock to be redeemed; (iv) the place or places where the certificates, if any, representing shares of Series H Preferred Stock are to be surrendered for payment of the redemption price;
(v) procedures for surrendering noncertificated shares of Series H Preferred Stock for payment of the redemption price; (vi) that dividends on the shares of Series H Preferred Stock to be redeemed will cease to accumulate on such
redemption date; and (vii) that payment of the redemption price and any accumulated and unpaid dividends will be made upon presentation and surrender of such Series H Preferred Stock. If fewer than all of the shares of Series H Preferred Stock
held by any holder are to be redeemed, the notice mailed to such holder shall also specify the number of shares of Series H Preferred Stock held by such holder to be redeemed. Notwithstanding anything else to the contrary in these Articles
Supplementary, the Company shall not be required to provide notice to the holder of Series H Preferred Stock in the event such holder’s Series H Preferred Stock is redeemed in accordance with Sections 5(c) and 9 of these Articles Supplementary
to preserve the Company’s status as a REIT. 
 (f) If a redemption date falls after a Dividend Record Date and on or prior
to the corresponding Dividend Payment Date, each holder of Series H Preferred Stock at the close of business of such Dividend Record Date 

  
 5 

 
shall be entitled to the dividend payable on such shares on the corresponding Dividend Payment Date notwithstanding the redemption of such shares on or prior to such Dividend Payment Date, and
each holder of Series H Preferred Stock that surrenders its shares on such redemption date will be entitled to the dividends accruing after the end of the Dividend Period to which such Dividend Payment Date relates up to but excluding the redemption
date. Except as provided herein, the Company shall make no payment or allowance for unpaid dividends, whether or not in arrears, on Series H Preferred Stock for which a notice of redemption has been given. 

(g) All shares of the Series H Preferred Stock redeemed or repurchased pursuant to this Section 5, or otherwise acquired in any
other manner by the Company, shall be retired and shall be restored to the status of authorized but unissued shares of Preferred Stock, without designation as to series or class. 

(h) The Series H Preferred Stock shall have no stated maturity and shall not be subject to any sinking fund or mandatory redemption;
provided, however, that the Series H Preferred Stock owned by a stockholder in excess of the applicable ownership limit shall be subject to the provisions of this Section 5 and Section 9 of these Articles Supplementary.

 Section 6. Special Optional Redemption by the Company. 

(a) Upon the occurrence of a Change of Control (as defined below), the Company will have the option upon written notice mailed by the
Company, postage pre-paid, no fewer than 30 nor more than 60 days prior to the redemption date and addressed to the holders of record of shares of the Series H Preferred Stock to be redeemed at their respective addresses as they appear on the share
transfer records of the Company, to redeem shares of the Series H Preferred Stock, in whole or in part within 120 days after the first date on which such Change of Control occurred, for cash at $25.00 per share plus accrued and unpaid dividends, if
any, to, but not including, the redemption date (“Special Optional Redemption Right”). No failure to give such notice or any defect thereto or in the mailing thereof shall affect the validity of the proceedings for the redemption of
any shares of Series H Preferred Stock except as to the holder to whom notice was defective or not given. If, prior to the Change of Control Conversion Date (as defined below), the Company has provided or provides notice of redemption with respect
to the Series H Preferred Stock (whether pursuant to the Redemption Right or the Special Optional Redemption Right), the holders of shares of Series H Preferred Stock will not have the conversion right described below in Section 8. 

A “Change of Control” is when, after the original issuance of the Series H Preferred Stock, the following have occurred
and are continuing: 
 (i) the acquisition by any person, including any syndicate or group deemed to be a “person”
under Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), of beneficial ownership, directly or indirectly, through a purchase, merger or other acquisition transaction or series of
purchases, mergers or other acquisition transactions of stock of the Company entitling that person to exercise more than 50% of the total voting power of all stock of the Company entitled to vote generally in the election of the Company’s
directors (except that such person will be deemed to have beneficial ownership of all securities that such person has the right to acquire, whether such right is currently exercisable or is exercisable only upon the occurrence of a subsequent
condition); and 
 (ii) following the closing of any transaction referred to in (i) above, neither the Company nor the
acquiring or surviving entity has a class of common securities (or American Depositary Receipts representing such securities) listed on the New York Stock Exchange (the “NYSE”), the NYSE MKT LLC (the “NYSE MKT”), or
the NASDAQ Stock Market (“NASDAQ”), or listed or quoted on an exchange or quotation system that is a successor to the NYSE, the NYSE MKT or NASDAQ. 
 (b) In addition to any information required by law or by the applicable rules of any exchange upon which the Series H Preferred Stock may be listed or admitted to trading, such notice shall state:
(i) the redemption date; (ii) the redemption price; (iii) the number of shares of Series H Preferred Stock to be redeemed; (iv) the place or places where the certificates, if any, representing shares of Series H Preferred Stock
are to be surrendered for payment of the redemption price; (v) procedures for surrendering noncertificated shares of Series H Preferred Stock for payment of the redemption price; (vi) that dividends on the shares of Series H Preferred
Stock to be redeemed will cease to accumulate on the redemption date; (vii) that payment of the redemption price and any 

  
 6 

 
accumulated and unpaid dividends will be made upon presentation and surrender of such Series H Preferred Stock; (viii) that the shares of Series H Preferred Stock are being redeemed pursuant
to the Special Optional Redemption Right in connection with the occurrence of a Change of Control and a brief description of the transaction or transactions constituting such Change of Control; and (ix) that holders of the shares of Series H
Preferred Stock to which the notice relates will not be able to tender such shares of Series H Preferred Stock for conversion in connection with the Change of Control and each share of Series H Preferred Stock tendered for conversion that is
selected, prior to the Change of Control Conversion Date, for redemption will be redeemed on the related redemption date instead of converted on the Change of Control Conversion Date. If fewer than all of the shares of Series H Preferred Stock held
by any holder are to be redeemed, the notice mailed to such holder shall also specify the number of shares of Series H Preferred Stock held by such holder to be redeemed. 
 If fewer than all of the outstanding shares of Series H Preferred Stock are to be redeemed, the shares of Series H Preferred Stock to be redeemed shall be redeemed pro rata (as nearly as may be
practicable without creating fractional shares) or by lot as determined by the Company. If such redemption pursuant to the Special Optional Redemption Right is to be by lot and, as a result, any holder of shares of Series H Preferred Stock would
have actual ownership, Beneficial Ownership or Constructive Ownership (each as defined in Section 9(a)) in excess of the Ownership Limit (as defined in Section 9(a)), the Aggregate Stock Ownership Limit (as defined in Section 9(a)),
or such limit as permitted by the Board of Directors or a committee thereof pursuant to Section 9(i), because such holder’s shares of Series H Preferred Stock were not redeemed, or were only redeemed in part then, except as otherwise
provided in the Charter, the Company shall redeem the requisite number of shares of Series H Preferred Stock of such holder such that no holder will hold an amount of Series H Preferred Stock in excess of the applicable ownership limit, subsequent
to such redemption. 
 (c) If the Company has given a notice of redemption pursuant to the Special Optional Redemption Right and
has set aside sufficient funds for the redemption in trust for the benefit of the holders of the Series H Preferred Stock called for redemption, then from and after the redemption date, those shares of Series H Preferred Stock will be treated as no
longer being outstanding, no further dividends will accrue and all other rights of the holders of those shares of Series H Preferred Stock will terminate. The holders of those shares of Series H Preferred Stock will retain their right to receive the
redemption price for their shares and any accrued and unpaid dividends to, but not including, the redemption date, without interest. So long as full cumulative dividends on the Series H Preferred Stock for all past dividend periods shall have been
or contemporaneously are (i) declared and paid in cash, or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for payment, nothing herein shall prevent or restrict the Company’s right or ability to
purchase, from time to time, either at a public or a private sale, all or any part of the Series H Preferred Stock at such price or prices as the Company may determine, subject to the provisions of applicable law, including the repurchase of shares
of Series H Preferred Stock in open-market transactions duly authorized by the Board of Directors. 
 (d) The holders of Series
H Preferred Stock at the close of business on a Dividend Record Date will be entitled to receive the dividend payable with respect to the Series H Preferred Stock on the corresponding Dividend Payment Date notwithstanding the redemption of the
Series H Preferred Stock pursuant to the Special Optional Redemption Right between such Dividend Record Date and the corresponding Dividend Payment Date or the Company’s default in the payment of the dividend due. Except as provided herein, the
Company shall make no payment or allowance for unpaid dividends, whether or not in arrears, on Series H Preferred Stock for which a notice of redemption pursuant to the Special Optional Redemption Right has been given. 

(e) All shares of the Series H Preferred Stock redeemed or repurchased pursuant to this Section 6, or otherwise acquired in any
other manner by the Company, shall be retired and shall be restored to the status of authorized but unissued shares of Preferred Stock, without designation as to series or class. 

Section 7. Voting Rights. 
 (a) Holders of the Series H Preferred Stock shall not have any voting rights, except as set forth in this Section 7. 
 (b) Whenever dividends on any shares of Series H Preferred Stock shall be in arrears for six or more consecutive or non-consecutive quarterly periods (a “Preferred Dividend Default”), the
holders of such Series

H Preferred Stock (voting separately as a class together with all other classes or series of preferred stock of the Company ranking on parity with the Series H Preferred Stock with respect to
payment of dividends and the distribution of assets upon the Company’s liquidation, dissolution or winding up and upon which like voting rights have been conferred and are exercisable (“Parity Preferred”), including the Series
E Cumulative Redeemable Preferred Stock, the Series F Cumulative Redeemable Preferred Stock and the Series G Cumulative Redeemable Preferred Stock of the Company) shall be entitled to vote for the election of a total of two additional directors of
the Company (the “Preferred Directors”) until all dividends accumulated on such Series H Preferred Stock and Parity Preferred for the past dividend periods shall have been fully paid or declared and a sum sufficient for the payment
thereof is set aside for payment. In such case, the entire Board of Directors will be increased by two directors. 
 (c) The
Preferred Directors will be elected by a plurality of the votes cast in the election for a one-year term and each Preferred Director will serve until his or her successor is duly elected and qualified or until such Preferred Director’s right to
hold the office terminates, whichever occurs earlier, subject to such Preferred Director’s earlier death, disqualification, resignation or removal. The election will take place at (i) either (A) a special meeting called in accordance
with Section 7(d) below if the request is received more than 90 days before the date fixed for the Company’s next annual or special meeting of stockholders or (B) the next annual or special meeting of stockholders if the request is
received within 90 days of the date fixed for the Company’s next annual or special meeting of stockholders, and (ii) at each subsequent annual meeting of stockholders, or special meeting held in place thereof, until all such dividends in
arrears on the Series H Preferred Stock and each such class or series of outstanding Parity Preferred have been paid in full. A dividend in respect of Series H Preferred Stock shall be considered timely made if made within two Business Days after
the applicable Dividend Payment Date if at the time of such late payment date there shall not be any prior quarterly dividend periods in respect of which full dividends were not timely made at the applicable Dividend Payment Date. 

(d) At any time when such voting rights shall have vested, a proper officer of the Company shall call or cause to be called, upon written
request of holders of record of at least 10% of the outstanding shares of Series H Preferred Stock and Parity Preferred, a special meeting of the holders of Series H Preferred Stock and each class or series of Parity Preferred by mailing or causing
to be mailed to such holders a notice of such special meeting to be held not fewer than ten or more than 45 days after the date such notice is given. The record date for determining holders of the Series H Preferred Stock and Parity Preferred
entitled to notice of and to vote at such special meeting will be the close of business on the third Business Day preceding the day on which such notice is mailed. At any such annual or special meeting, all of the holders of the Series H Preferred
Stock and Parity Preferred, by plurality vote, voting together as a single class without regard to class or series will be entitled to elect two directors on the basis of one vote per $25.00 of liquidation preference to which such Series H Preferred
Stock and Parity Preferred are entitled by their terms (excluding amounts in respect of accumulated and unpaid dividends) and not cumulatively. The holder or holders of one-third of the Series H Preferred Stock and Parity Preferred voting as a
single class then outstanding, present in person or by proxy, will constitute a quorum for the election of the Preferred Directors except as otherwise provided by law. Notice of all meetings at which holders of the Series H Preferred Stock and the
Parity Preferred shall be entitled to vote will be given to such holders at their addresses as they appear in the transfer records. At any such meeting or adjournment thereof in the absence of a quorum, subject to the provisions of any applicable
law, a majority of the holders of the Series H Preferred Stock and Parity Preferred voting as a single class present in person or by proxy shall have the power to adjourn the meeting for the election of the Preferred Directors, without notice other
than an announcement at the meeting, until a quorum is present. If a Preferred Dividend Default shall terminate after the notice of a special meeting has been given but before such special meeting has been held, the Company shall, as soon as
practicable after such termination, mail or cause to be mailed notice of such termination to holders of the Series H Preferred Stock and the Parity Preferred that would have been entitled to vote at such special meeting. 

(e) If and when all accumulated dividends on such Series H Preferred Stock and all classes or series of Parity Preferred for the past
dividend periods shall have been fully paid or declared and a sum sufficient for the payment thereof is set aside for payment, the right of the holders of Series H Preferred Stock and the Parity Preferred to elect such additional two directors shall
immediately cease (subject to revesting in the event of each and every Preferred Dividend Default), and the term of office of each Preferred Director so elected shall terminate and the entire Board of Directors shall be reduced accordingly. Any
Preferred Director may be removed at any time with or without cause by the vote of, and shall not be removed otherwise than by the vote of, the holders of record of a majority of the outstanding Series H Preferred Stock and the Parity Preferred
entitled to vote thereon when they 

  
 8 

 
have the voting rights set forth in Section 7(b) (voting as a single class). So long as a Preferred Dividend Default shall continue, any vacancy in the office of a Preferred Director may be
filled by written consent of the Preferred Director remaining in office, or if none remains in office, by a vote of the holders of record of a majority of the outstanding Series H Preferred Stock when they have the voting rights described above
(voting as a single class with all other classes or series of Parity Preferred). Each of the Preferred Directors shall be entitled to one vote on any matter. 
 (f) So long as any shares of Series H Preferred Stock remain outstanding, the affirmative vote or consent of the holders of two-thirds of the shares of Series H Preferred Stock and each other class or
series of Parity Preferred outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting together as a single class) will be required to: (i) authorize, create or issue, or increase the number of authorized or
issued shares of, any class or series of capital stock ranking senior to the Series H Preferred Stock with respect to payment of dividends or the distribution of assets upon liquidation, dissolution or winding up of the Company (collectively,
“Senior Capital Stock”) or reclassify any authorized shares of capital stock of the Company into such capital stock, or create, authorize or issue any obligation or security convertible into or evidencing the right to purchase any
such Senior Capital Stock; or (ii) amend, alter or repeal the provisions of the Charter, including the terms of the Series H Preferred Stock, whether by merger, consolidation, transfer or conveyance of all or substantially all of its assets or
otherwise (an “Event”), so as to materially and adversely affect any right, preference, privilege or voting power of the Series H Preferred Stock; provided however, with respect to the occurrence of any of the Events
set forth in (ii) above, so long as the Series H Preferred Stock remains outstanding with the terms thereof materially unchanged, taking into account that, upon the occurrence of an Event, the Company may not be the surviving entity, the
occurrence of such Event shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting power of Series H Preferred Stock, and in such case such holders shall not have any voting rights with respect to the
occurrence of any of the Events set forth in (ii) above. In addition, if the holders of the Series H Preferred Stock receive the greater of the full trading price of the Series H Preferred Stock on the date of an Event set forth in
(ii) above or the $25.00 liquidation preference per share of the Series H Preferred Stock pursuant to the occurrence of any of the Events set forth in (ii) above, then such holders shall not have any voting rights with respect to the
Events set forth in (ii) above. If any Event set forth in (ii) above would materially and adversely affect the rights, preferences, privileges or voting powers of the Series H Preferred Stock disproportionately relative to other classes or
series of Parity Preferred, the affirmative vote of the holders of at least two-thirds of the outstanding shares of the Series H Preferred Stock, voting separately as a class, will also be required. Holders of shares of Series H Preferred Stock
shall not be entitled to vote with respect to (A) any increase in the total number of authorized shares of Common Stock or Preferred Stock of the Company, or (B) any increase in the number of authorized shares of Series H Preferred Stock
or the creation or issuance of any other class or series of capital stock, or (C) any increase in the number of authorized shares of any other class or series of capital stock, in each case referred to in clause (A), (B) or (C) above
ranking on parity with or junior to the Series H Preferred Stock with respect to the payment of dividends and the distribution of assets upon liquidation, dissolution or winding up of the Company. Except as set forth herein, holders of the Series H
Preferred Stock shall not have any voting rights with respect to, and the consent of the holders of the Series H Preferred Stock shall not be required for, the taking of any corporate action, including an Event, regardless of the effect that such
corporate action or Event may have upon the powers, preferences, voting power or other rights or privileges of the Series H Preferred Stock. 
 (g) The foregoing voting provisions of this Section 7 shall not apply if, at or prior to the time when the act with respect to which such vote would otherwise be required shall be effected, all
outstanding shares of Series H Preferred Stock shall have been redeemed or called for redemption upon proper notice pursuant to these Articles Supplementary, and sufficient funds, in cash, shall have been deposited in trust to effect such
redemption. 
 (h) In any matter in which the Series H Preferred Stock may vote (as expressly provided herein), each share of
Series H Preferred Stock shall be entitled to one vote per $25.00 of liquidation preference. 
 Section 8.
Conversion. The shares of Series H Preferred Stock are not convertible into or exchangeable for any other property or securities of the Company, except as provided in this Section 8. 

(a) Upon the occurrence of a Change of Control, each holder of shares of Series H Preferred Stock shall have the right, unless, prior to
the Change of Control Conversion Date, the Company has provided or provides notice of its election to redeem the Series H Preferred Stock pursuant to the Redemption Right or Special 

  
 9 

 
Optional Redemption Right, to convert some or all of the Series H Preferred Stock held by such holder (the “Change of Control Conversion Right”) on the Change of Control
Conversion Date into a number of shares of Common Stock, per share of Series H Preferred Stock to be converted (the “Common Stock Conversion Consideration”) equal to the lesser of (A) the quotient obtained by dividing
(i) the sum of (x) the $25.00 liquidation preference per share of Series H Preferred Stock to be converted plus (y) the amount of any accrued and unpaid dividends to, but not including, the Change of Control Conversion Date (unless
the Change of Control Conversion Date is after a Dividend Record Date and prior to the corresponding Dividend Payment Date, in which case no additional amount for such accrued and unpaid dividends will be included in such sum) by (ii) the
Common Stock Price (as defined herein) and (B) 0.9632 (the “Share Cap”), subject to the immediately succeeding paragraph. 
 The Share Cap is subject to pro rata adjustments for any share splits (including those effected pursuant to a distribution of the Common Stock), subdivisions or combinations (in each case, a
“Share Split”) with respect to the Common Stock as follows: the adjusted Share Cap as the result of a Share Split shall be the number of shares of Common Stock that is equivalent to the product obtained by multiplying (i) the
Share Cap in effect immediately prior to such Share Split by (ii) a fraction, the numerator of which is the number of shares of Common Stock outstanding after giving effect to such Share Split and the denominator of which is the number of
shares of Common Stock outstanding immediately prior to such Share Split. 
 For the avoidance of doubt, subject to the
immediately succeeding sentence, the aggregate number of shares of Common Stock (or equivalent Alternative Conversion Consideration (as defined below), as applicable) issuable in connection with the exercise of the Change of Control Conversion Right
shall not exceed 11,558,400 shares of Common Stock (or equivalent Alternative Conversion Consideration, as applicable), subject to increase to the extent the underwriters’ over-allotment option to purchase additional shares of Series H
Preferred Stock in the initial public offering of Series H Preferred Stock is exercised, not to exceed 13,292,160 shares of Common Stock in total (or equivalent Alternative Conversion Consideration, as applicable) (the “Exchange
Cap”). The Exchange Cap is subject to pro rata adjustments for any Share Splits on the same basis as the corresponding adjustment to the Share Cap. 
 In the case of a Change of Control pursuant to which shares of Common Stock shall be converted into cash, securities or other property or assets (including any combination thereof) (the
“Alternative Form Consideration”), a holder of shares of Series H Preferred Stock shall receive upon conversion of such shares of Series H Preferred Stock the kind and amount of Alternative Form Consideration which such holder would
have owned or been entitled to receive upon the Change of Control had such holder held a number of shares of Common Stock equal to the Common Stock Conversion Consideration immediately prior to the effective time of the Change of Control (the
“Alternative Conversion Consideration”; and the Common Stock Conversion Consideration or the Alternative Conversion Consideration, as may be applicable to a Change of Control, shall be referred to herein as the “Conversion
Consideration”). 
 In the event that holders of Common Stock have the opportunity to elect the form of consideration
to be received in the Change of Control, the Conversion Consideration will be deemed to be the kind and amount of consideration actually received by holders of a majority of the Common Stock that voted for such an election (if electing between two
types of consideration) or holders of a plurality of the Common Stock that voted for such an election (if electing between more than two types of consideration), as the case may be, and will be subject to any limitations to which all holders of
Common Stock are subject, including, without limitation, pro rata reductions applicable to any portion of the consideration payable in the Change of Control. 
 The “Change of Control Conversion Date” shall be a Business Day set forth in the notice of Change of Control provided in accordance with Section 8(c) below that is no less than 20
days nor more than 35 days after the date on which the Company provides such notice pursuant to Section 8(c). 
 The
“Common Stock Price” shall be (i) if the consideration to be received in the Change of Control by the holders of Common Stock is solely cash, the amount of cash consideration per share of Common Stock or (ii) if the
consideration to be received in the Change of Control by holders of Common Stock is other than solely cash (x) the average of the closing sale prices per share of Common Stock (or, if no closing sale price is reported, the average of the
closing bid and ask prices or, if more than one in either case, the average of the average closing bid and the average closing ask prices) for the ten consecutive trading days immediately preceding, but

  
 10 

 
not including, the effective date of the Change of Control as reported on the principal U.S. securities exchange on which the Common Stock is then traded, or (y) the average of the last
quoted bid prices for the Common Stock in the over-the-counter market as reported by Pink Sheets LLC or similar organization for the ten consecutive trading days immediately preceding, but not including, the effective date of the Change of Control,
if the Common Stock is not then listed for trading on a U.S. securities exchange. 
 (b) No fractional shares of Common Stock
shall be issued upon the conversion of Series H Preferred Stock. In lieu of fractional shares, holders shall be entitled to receive the cash value of such fractional shares based on the Common Stock Price. 

(c) Within 15 days following the occurrence of a Change of Control, a notice of occurrence of the Change of Control, describing the
resulting Change of Control Conversion Right, shall be delivered to the holders of record of the shares of Series H Preferred Stock at their addresses as they appear on the Company’s share transfer records and notice shall be provided to the
Company’s transfer agent. No failure to give such notice or any defect thereto or in the mailing thereof shall affect the validity of the proceedings for the conversion of any share of Series H Preferred Stock except as to the holder to whom
notice was defective or not given. Each notice shall state: (i) the events constituting the Change of Control; (ii) the date of the Change of Control; (iii) the last date on which the holders of Series H Preferred Stock may exercise
their Change of Control Conversion Right; (iv) the method and period for calculating the Common Stock Price; (v) the Change of Control Conversion Date, which shall be a Business Day occurring within 20 to 35 days following the date of such
notice; (vi) that if, prior to the Change of Control Conversion Date, the Company has provided or provides notice of its election to redeem all or any portion of the Series H Preferred Stock, the holder will not be able to convert shares of
Series H Preferred Stock designated for redemption and such shares of Series H Preferred Stock shall be redeemed on the related redemption date, even if they have already been tendered for conversion pursuant to the Change of Control Conversion
Right; (vii) if applicable, the type and amount of Alternative Conversion Consideration entitled to be received per share of Series H Preferred Stock; (viii) the name and address of the paying agent and the conversion agent; and
(ix) the procedures that the holders of Series H Preferred Stock must follow to exercise the Change of Control Conversion Right. 
 (d) The Company shall issue a press release for publication on the Dow Jones & Company, Inc., Business Wire, PR Newswire 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), or post notice on the Company’s website, in any event prior to the
opening of business on the first Business Day following any date on which the Company provides notice pursuant to Section 8(c) above to the holders of Series H Preferred Stock. 

(e) In order to exercise the Change of Control Conversion Right, a holder of shares of Series H Preferred Stock shall be required to
deliver, on or before the close of business on the Change of Control Conversion Date, the certificates (if any) representing the shares of Series H Preferred Stock to be converted, duly endorsed for transfer, together with a written conversion
notice completed, to the Company’s transfer agent. Such notice shall state: (i) the relevant Change of Control Conversion Date; (ii) the number of shares of Series H Preferred Stock to be converted; and (iii) that the shares of
Series H Preferred Stock are to be converted pursuant to the applicable provisions of these Articles Supplementary. Notwithstanding the foregoing, if the shares of Series H Preferred Stock are held in global form, such notice shall comply with
applicable procedures of The Depository Trust Company (“DTC”). 
 (f) Holders of Series H Preferred Stock may
withdraw any notice of exercise of a Change of Control Conversion Right (in whole or in part) by a written notice of withdrawal delivered to the Company’s transfer agent prior to the close of business on the Business Day prior to the Change of
Control Conversion Date. The notice of withdrawal must state: (i) the number of withdrawn shares of Series H Preferred Stock; (ii) if certificated shares of Series H Preferred Stock have been issued, the certificate numbers of the shares
of withdrawn Series H Preferred Stock; and (iii) the number of shares of Series H Preferred Stock, if any, which remain subject to the conversion notice. Notwithstanding the foregoing, if the shares of Series H Preferred Stock are held in
global form, the notice of withdrawal shall comply with applicable procedures of DTC. 
 (g) Shares of Series H Preferred Stock
as to which the Change of Control Conversion Right has been properly exercised and for which the conversion notice has not been properly withdrawn shall be converted into 

  
 11 

 
the applicable Conversion Consideration in accordance with the Change of Control Conversion Right on the Change of Control Conversion Date, unless, prior to the Change of Control Conversion Date,
the Company has provided or provides notice of its election to redeem such shares of Series H Preferred Stock, whether pursuant to its Redemption Right or Special Optional Redemption Right. If the Company elects to redeem shares of Series H
Preferred Stock that would otherwise be converted into the applicable Conversion Consideration on a Change of Control Conversion Date, such shares of Series H Preferred Stock shall not be so converted and the holders of such shares shall be entitled
to receive on the applicable redemption date $25.00 per share, plus any accrued and unpaid dividends thereon to, but not including, the redemption date. 
 (h) The Company shall deliver the applicable Conversion Consideration no later than the third Business Day following the Change of Control Conversion Date. 

(i) Notwithstanding anything to the contrary contained herein, no holder of shares of Series H Preferred Stock will be entitled to
convert such shares of Series H Preferred Stock into shares of Common Stock to the extent that receipt of such shares of Common Stock would cause the holder of such shares of Common Stock (or any other person) to have actual ownership, Beneficial
Ownership or Constructive Ownership (each as defined in Section 9(a)) in excess of the Ownership Limit (as defined in Section 9(a)), the Aggregate Stock Ownership Limit (as defined in Section 9(a)), or such other limit as permitted by
the Board of Directors or the Committee pursuant to Section 9(i).

discovery by the Company that shares of Series H Preferred Stock have been transferred to the Trustee shall be paid to the Trustee upon demand, and any dividend or distribution declared but unpaid shall be paid when due to the Trustee with respect

Series H Preferred Stock have been transferred to the Trust, the Trustee of the Trust shall sell the shares of Series H Preferred Stock held in the Trust to a Person, designated by the Trustee, whose ownership of the shares of Series H Preferred
Stock will not violate the ownership limitations set forth in Section 9(b)(i). Upon such sale, the interest of the Charitable Beneficiary in the shares of Series H Preferred Stock sold shall terminate and the Trustee shall distribute the net
proceeds of the sale to the Purported Record Transferee and to the Charitable Beneficiary as provided in this Section 9(c)(iv). The Purported Record Transferee shall receive the lesser of (A) the price paid by the Purported Record
Transferee for the shares of Series H Preferred Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Series H Preferred Stock
at Market Price, the Market Price of such shares of Series H Preferred Stock on the day of the event which resulted in the transfer of such shares of Series H Preferred Stock to the Trust) and (B) the price per share received by the Trustee
(net of any commissions and other expenses of sale) from the sale or other disposition of the shares of Series H Preferred Stock held in the Trust. The Trustee may reduce the amount payable to the Purported Record Transferee by the amount of
dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 9(c)(iii). Any net sales proceeds in excess of the amount payable to the
Purported Record Transferee shall be immediately paid to the Charitable Beneficiary together with any dividends or other distributions thereon. If, prior to the discovery by the Company that shares of such Series H Preferred Stock have been
transferred to the Trustee, such shares of Series H Preferred Stock are sold by a Purported Record Transferee then (1) such shares of Series H Preferred Stock shall be deemed to have been sold on behalf of the Trust and (2) to the extent
that the Purported Record Transferee received an amount for such shares of Series H Preferred Stock that exceeds the amount that such Purported Record Transferee was entitled to receive pursuant to this Section 9(c)(iv), such excess shall be
paid to the Trustee upon demand. 
 (v) Series H Preferred Stock transferred to the Trustee shall be deemed to have been offered
for sale to the Company, or its designee, at a price per share equal to the lesser of (A) the price paid by the 

  
 15 

 
Purported Record Transferee for the shares of Series H Preferred Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust
did not involve a purchase of such shares of Series H Preferred Stock at Market Price, the Market Price of such shares of Series H Preferred Stock on the day of the event which resulted in the transfer of such shares of Series H Preferred Stock to
the Trust) and (B) the Market Price on the date the Company, or its designee, accepts such offer. The Company may reduce the amount payable to the Purported Record Transferee by the amount of dividends and distributions which have been paid to
the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 9(c)(iii). The Company shall have the right to accept such offer until the Trustee has sold the shares of Series H Preferred
Stock held in the Trust pursuant to Section 9(c)(iv). Upon such a sale to the Company, the interest of the Charitable Beneficiary in the shares of Series H Preferred Stock sold shall terminate and the Trustee shall distribute the net proceeds
of the sale to the Purported Record Transferee and any dividends or other distributions held by the Trustee with respect to such Series H Preferred Stock shall thereupon be paid to the Charitable Beneficiary. 

(vi) By written notice to the Trustee, the Company shall designate one or more nonprofit organizations to be the Charitable Beneficiary
of the interest in the Trust such that the Series H Preferred Stock held in the Trust would not violate the restrictions set forth in Section 9(b)(i) in the hands of such Charitable Beneficiary. 

(d) Remedies For Breach. If the Board of Directors or a committee thereof or other designees if permitted by the MGCL shall at any
time determine in good faith that a Transfer or other event has taken place in violation of Section 9(b) of these Articles Supplementary or that a Person intends to acquire, has attempted to acquire or may acquire beneficial ownership
(determined without reference to any rules of attribution), Beneficial Ownership or Constructive Ownership of any shares of Series H Preferred Stock of the Company in violation of Section 9(b) of these Articles Supplementary, the Board of
Directors or the Committee or other designees if permitted by the MGCL shall take such action as it deems advisable to refuse to give effect or to prevent such Transfer, including, but not limited to, causing the Company to redeem shares of Series H
Preferred Stock, refusing to give effect to such Transfer on the books of the Company or instituting proceedings to enjoin such Transfer; provided, however, that any Transfers (or, in the case of events other than a Transfer, ownership
or Constructive Ownership or Beneficial Ownership) in violation of Section 9(b)(i) of these Articles Supplementary, shall automatically result in the transfer to a Trust as described in Section 9(b)(ii) and any Transfer in violation of
Section 9(b)(iii) shall automatically be void ab initio irrespective of any action (or non-action) by the Board of Directors. 
 (e) Notice of Restricted Transfer. Any Person who acquires or attempts to acquire shares of Series H Preferred Stock in violation of Section 9(b) of these Articles Supplementary, or any Person
who is a Purported Beneficial Transferee such that an automatic transfer to a Trust results under Section 9(b)(ii) of these Articles Supplementary, shall immediately give written notice to the Company of such event and shall provide to the
Company such other information as the Company may request in order to determine the effect, if any, of such Transfer or attempted Transfer on the Company’s status as a REIT. 

(f) Owners Required To Provide Information. Prior to the Restriction Termination Date each Person who is a beneficial owner or
Beneficial Owner or Constructive Owner of Series H Preferred Stock and each Person (including the stockholder of record) who is holding Series H Preferred Stock for a beneficial owner or Beneficial Owner or Constructive Owner shall provide to the
Company such information that the Company may request, in good faith, in order to determine the Company’s status as a REIT. 
 (g) Remedies Not Limited. Nothing contained in these Articles Supplementary (but subject to Section 9(l) of these Articles Supplementary) shall limit the authority of the Board of Directors to
take such other action as it deems necessary or advisable to protect the Company and the interests of its stockholders by preservation of the Company’s status as a REIT. 
 (h) Ambiguity. In the case of an ambiguity in the application of any of the provisions of this Section 9 of these Articles Supplementary, including any definition contained in
Section 9(a), the Board of Directors shall have the power to determine the application of the provisions of this Section 9 with respect to any situation based on the facts known to it (subject, however, to the provisions of
Section 9(l) of these Articles Supplementary). In the event Section 9 requires an action by the Board of Directors and these Articles Supplementary fail to provide specific guidance with respect to such action, the Board of Directors shall
have the power to determine the action to 

  
 16 

 
be taken so long as such action is not contrary to the provisions of Section 9. Absent a decision to the contrary by the Board of Directors (which the Board of Directors may make in its sole
and absolute discretion), if a Person would have (but for the remedies set forth in Section 9(b)) acquired Beneficial or Constructive Ownership of Series H Preferred Stock in violation of Section 9(b)(i), such remedies (as applicable)
shall apply first to the shares of Series H Preferred Stock which, but for such remedies, would have been actually owned by such Person, and second to shares of Series H Preferred Stock, which, but for such remedies, would have been Beneficially
Owned or Constructively Owned (but not actually owned) by such Person, pro rata among the Persons who actually own such shares of Series H Preferred Stock based upon the relative number of the shares of Series H Preferred Stock held by each such
Person. 
 (i) Exceptions. 
 (i) Subject to Section 9(b)(i)(C), the Board of Directors, in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Beneficially Owning shares of
Series H Preferred Stock in violation of Section 9(b)(i)(A) if the Board of Directors determines that such exemption will not cause any Individual’s Beneficial Ownership of shares of Capital Stock to violate the Aggregate Stock Ownership
Limit and that such exemption will not cause the Company to fail to qualify as a REIT under the Code. 
 (ii) Subject to
Section 9(b)(i)(C), the Board of Directors in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Constructively Owning shares of Series H Preferred Stock in violation of
Section 9(b)(i)(B), if the Board of Directors determines that such ownership would not cause the Company to fail to qualify as a REIT under the Code. 
 (iii) Subject to Section 9(b)(i)(C) and the remainder of this Section 9(i)(iii), the Board of Directors may from time to time increase or decrease the Ownership Limit; provided,
however, that the decreased Ownership Limit will not be effective for any Person whose percentage ownership of Series H Preferred Stock is in excess of such decreased Ownership Limit until such time as such Person’s percentage of Series
H Preferred Stock equals or falls below the decreased Ownership Limit, but any further acquisition of Series H Preferred Stock in excess of such percentage ownership of Series H Preferred Stock will be in violation of the Ownership Limit, and,
provided further, that the new Ownership Limit would not allow five or fewer Persons to Beneficially Own more than 49% in value of the outstanding capital stock of the Company. 

(iv) In granting a Person an exemption under Section 9(i)(i) or (ii) above, the Board of Directors may require such Person to
make certain representations or undertakings or to agree that any violation or attempted violation of such representations or undertakings (or other action which is contrary to the restrictions contained in Section 9(b) of these Articles
Supplementary) will result in such Series H Preferred Stock being transferred to a Trust in accordance with Section 9(b)(ii) of these Articles Supplementary. In granting any exception pursuant to Section 9(i)(i) or (ii) of these
Articles Supplementary, the Board of Directors may require a ruling from the IRS, or an opinion of counsel, in either case in form and substance satisfactory to the Board of Directors in its sole discretion, as it may deem necessary or advisable in
order to determine or ensure the Company’s status as a REIT. 
 (j) Legends. Each certificate for Series H Preferred
Stock shall bear substantially the following legends in addition to any legends required to comply with federal and state securities laws: 
 Classes of Stock 
 “THE COMPANY IS AUTHORIZED TO ISSUE CAPITAL STOCK OF
MORE THAN ONE CLASS, CONSISTING OF COMMON STOCK AND ONE OR MORE CLASSES OF PREFERRED STOCK. THE BOARD OF DIRECTORS IS AUTHORIZED TO DETERMINE THE PREFERENCES, LIMITATIONS AND RELATIVE RIGHTS OF ANY CLASS OF THE PREFERRED STOCK BEFORE THE ISSUANCE OF
SHARES OF SUCH CLASS OF PREFERRED STOCK. THE COMPANY WILL FURNISH, WITHOUT CHARGE, TO ANY STOCKHOLDER MAKING A WRITTEN REQUEST THEREFOR, A COPY OF THE COMPANY’S CHARTER AND A WRITTEN STATEMENT OF THE DESIGNATIONS, RELATIVE RIGHTS, PREFERENCES,
CONVERSION OR OTHER RIGHTS, VOTING POWERS, RESTRICTIONS, LIMITATIONS AS TO DIVIDENDS 

  
 17 

 
AND OTHER DISTRIBUTIONS, QUALIFICATIONS AND TERMS AND CONDITIONS OF REDEMPTION OF THE STOCK OF EACH CLASS WHICH THE COMPANY HAS THE AUTHORITY TO ISSUE AND, IF THE COMPANY IS AUTHORIZED TO ISSUE

COMPANY’S MAINTENANCE OF ITS STATUS AS A REAL ESTATE INVESTMENT TRUST UNDER THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”). SUBJECT TO CERTAIN FURTHER RESTRICTIONS AND EXCEPT AS EXPRESSLY PROVIDED IN THE ARTICLES
SUPPLEMENTARY FOR THE SERIES H PREFERRED STOCK, (i) NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF SERIES H PREFERRED STOCK IN EXCESS OF 9.8% (BY VALUE OR BY NUMBER OF SHARES, WHICHEVER IS MORE RESTRICTIVE) OF THE OUTSTANDING SERIES
H PREFERRED STOCK OF THE COMPANY; (ii) NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF SERIES H PREFERRED STOCK THAT, TAKING INTO ACCOUNT ANY OTHER CAPITAL STOCK OF THE COMPANY BENEFICIALLY OR CONSTRUCTIVELY OWNED BY SUCH PERSON,
WOULD RESULT IN SUCH PERSON BENEFICIALLY OR CONSTRUCTIVELY OWNING CAPITAL STOCK WITH A VALUE IN EXCESS OF 9.8% OF THE VALUE OF THE COMPANY’S OUTSTANDING CAPITAL STOCK; (iii) NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF SERIES
H PREFERRED STOCK THAT, TAKING INTO ACCOUNT ANY OTHER CAPITAL STOCK OF THE COMPANY BENEFICIALLY OR CONSTRUCTIVELY OWNED BY SUCH PERSON, WOULD RESULT IN THE COMPANY BEING “CLOSELY HELD” UNDER SECTION 856(h) OF THE CODE OR OTHERWISE CAUSE
THE COMPANY TO FAIL TO QUALIFY AS A REIT; AND (iv) ANY TRANSFER OF SHARES OF SERIES H PREFERRED STOCK THAT, IF EFFECTIVE, WOULD RESULT IN THE CAPITAL STOCK OF THE COMPANY BEING BENEFICIALLY OWNED BY FEWER THAN 100 PERSONS WILL BE VOID AB
INITIO AND THE INTENDED TRANSFEREE WILL ACQUIRE NO RIGHTS IN SUCH SHARES OF SERIES H PREFERRED STOCK. ANY PERSON WHO BENEFICIALLY OR CONSTRUCTIVELY OWNS OR ATTEMPTS TO BENEFICIALLY OR CONSTRUCTIVELY OWN SERIES H PREFERRED STOCK WHICH CAUSES OR
WILL CAUSE A PERSON TO BENEFICIALLY OR CONSTRUCTIVELY OWN SERIES H PREFERRED STOCK IN EXCESS OF THE ABOVE LIMITATIONS MUST IMMEDIATELY NOTIFY THE COMPANY. IF ANY OF THE RESTRICTIONS ON TRANSFER OR OWNERSHIP IN (i) THROUGH (iii) ABOVE ARE
VIOLATED, THE SERIES H PREFERRED STOCK REPRESENTED HEREBY IN EXCESS OF SUCH RESTRICTIONS WILL BE AUTOMATICALLY TRANSFERRED TO THE TRUSTEE OF A TRUST FOR THE BENEFIT OF ONE OR MORE CHARITABLE BENEFICIARIES. IN ADDITION, THE COMPANY MAY REDEEM SHARES
UPON THE TERMS AND CONDITIONS SPECIFIED BY THE BOARD OF DIRECTORS IN ITS SOLE DISCRETION IF THE BOARD OF DIRECTORS DETERMINES THAT OWNERSHIP OR A TRANSFER OR OTHER EVENT MAY VIOLATE THE RESTRICTIONS DESCRIBED ABOVE. FURTHERMORE, UPON THE OCCURRENCE
OF CERTAIN EVENTS, ATTEMPTED TRANSFERS IN VIOLATION OF THE RESTRICTIONS DESCRIBED ABOVE MAY BE VOID AB INITIO. ALL TERMS IN THIS LEGEND WHICH ARE DEFINED IN THE ARTICLES SUPPLEMENTARY FOR THE SERIES H PREFERRED STOCK SHALL HAVE THE MEANINGS
ASCRIBED TO THEM IN SUCH ARTICLES SUPPLEMENTARY, AS THE SAME MAY BE AMENDED FROM TIME TO TIME, A COPY OF WHICH, INCLUDING THE RESTRICTIONS ON TRANSFER AND OWNERSHIP, WILL BE FURNISHED TO EACH 

  
 18 

 
HOLDER OF SERIES H PREFERRED STOCK ON REQUEST AND WITHOUT CHARGE. REQUESTS FOR SUCH A COPY MAY BE DIRECTED TO THE SECRETARY OF THE COMPANY AT ITS PRINCIPAL OFFICE.” 

(k) Severability. If any provision of this Section 9 or any application of any such provision is determined to be invalid by
any federal or state court having jurisdiction over the issues, the validity of the remaining provisions shall not be affected and other applications of such provision shall be affected only to the extent necessary to comply with the determination
of such court. 
 (l) NYSE. Nothing in this Section 9 shall preclude the settlement of any transaction entered into
through the facilities of the NYSE. The shares of Series H Preferred Stock that are the subject of such transaction shall continue to be subject to the provisions of this Section 9 after such settlement. 

(m) Applicability of Section 9. The provisions set forth in this Section 9 shall apply to the Series H Preferred Stock
notwithstanding any contrary provisions of the Series H Preferred Stock provided for elsewhere in these Articles Supplementary. 

Section 10. No Conversion Rights. The shares of Series H Preferred Stock shall not be convertible into or exchangeable for
any other property or securities of the Company or any other entity, except as otherwise provided herein.

any notice to the contrary.

date, and no sinking fund has been established for the retirement or redemption of Series H Preferred Stock; provided, however, that the Series H Preferred Stock owned by a stockholder in excess of the Ownership Limit or Aggregate
Stock Ownership Limit shall be subject to the provisions of Section 5 and Section 9 of this Articles Supplementary. 

Section 13. Exclusion of Other Rights. The Series H Preferred Stock shall not have any preferences or other rights, voting
powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption other than expressly set forth in the Charter and these Articles Supplementary. 

Section 14. Headings of Subdivisions. The headings of the various subdivisions hereof are for convenience of reference only
and shall not affect the interpretation of any of the provisions hereof. 
 Section 15. Severability of Provisions.
If any preferences or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption of the Series H Preferred Stock set forth in the Charter and these Articles
Supplementary are invalid, unlawful or incapable of being enforced by reason of any rule of law or public policy, all other preferences or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications
or terms or conditions of redemption of Series H Preferred Stock set forth in the Charter which can be given effect without the invalid, unlawful or unenforceable provision thereof shall, nevertheless, remain in full force and effect and no
preferences or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption of the Series H Preferred Stock herein set forth shall be deemed dependent upon any
other provision thereof unless so expressed therein. 
 Section 16. No Preemptive Rights. No holder of Series H
