 (3) Rank. Any class or series of shares of beneficial interest of the Trust shall be deemed to rank: 
 (a) prior to the Series 1 Preferred Shares, as to the payment of dividends and as to distribution of assets upon liquidation, dissolution or winding up, if the holders of such class or series shall be entitled to the receipt of dividends or

 3 








 (b) on a parity with the Series 1 Preferred Shares, as to the payment of dividends and as to distribution
of assets upon liquidation, dissolution or winding up, whether or not the dividend rates, dividend payment dates or redemption or liquidation prices per share thereof be different from those of the Series 1 Preferred Shares, if the holders of such
class or series of shares, which shall include the Series 1 Preferred Shares, shall be entitled to the receipt of dividends and of amounts distributable upon liquidation, dissolution or winding up in proportion to their respective amounts of accrued
and unpaid dividends per share or liquidation preferences, without preference or priority one over the other (“Parity Shares”); and 
 (c) junior to the Series 1 Preferred Shares, as to the payment of dividends or as to the distribution of assets upon liquidation, dissolution or winding up, if such shares shall be Junior Shares. 
 (4) Dividends. 
 (a) The holders of
Series 1 Preferred Shares shall be entitled to receive, when, as and if authorized by the Board of Trustees out of funds legally available for that purpose, cumulative, preferential dividends payable in cash at the rate of 5.417% of the Liquidation
Price per year (an amount of $1.35425 per annum per share). Such dividends shall begin to accrue and shall be fully cumulative from the Issue Date, whether or not the Trust has earnings, and whether or not in any Dividend Period or Periods there
shall be funds of the Trust legally available for the payment of such dividends, and shall be payable quarterly, when, as and if authorized by the Board of Trustees, in arrears, on Dividend Payment Dates, commencing on the first Dividend Payment
Date occurring after April 1, 2007. Such dividends shall be payable in arrears to the holders of record of Series 1 Preferred Shares, as they appear on the stock records of the Trust at the close of business on the record date as shall be fixed
by the Board of Trustees. Accrued and unpaid dividends for any past Dividend Periods may be declared and paid on any date and for such interim periods, without reference to any regular Dividend Payment Date, to holders of record on such date, as may
be fixed by the Board of Trustees. Any dividend payment made on the Series 1 Preferred Shares shall first be credited against the earliest accrued but unpaid dividend due with respect to the Series 1 Preferred Shares which remains payable.

 (b) The amount of dividends referred to in Section 4(a) payable for each full Dividend Period for the Series 1 Preferred
Shares shall be computed by dividing the annual dividend rate by four, except that the amount of dividends payable for the initial Dividend Period, and for any Dividend Period shorter than a full Dividend Period, shall be computed for the Series 1
Preferred Shares on the basis of the actual number of days in such Dividend Period. Holders of Series 1 Preferred Shares shall not be entitled to any dividends, whether payable in cash, property or shares of stock, in excess of cumulative dividends,
as herein provided, on the Series 1 Preferred Shares. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or payments on the Series 1 Preferred Shares that may be in arrears. 
 (c) If, for any taxable year, the Trust elects to designate as “capital gain dividends” (as defined in Section 857 of the Code) any
portion (the “Capital Gains Amount”) of the total dividends (within the meaning of the Code) paid or made available for the year to holders of all classes of shares of beneficial interest (the “Total Dividends”), then the portion
of the Capital Gains Amount that shall be allocated to holders of Series 1 Preferred Shares shall be in the same portion that the Total Dividends paid or made available to the holders of Series 1 Preferred Shares for the year bears to the Total
Dividends. 
 (d) So long as any Series 1 Preferred Shares are outstanding, no dividends, except as described in the immediately following
sentence, shall be declared or paid or set apart for payment on any class or series of Parity Shares for any period unless full cumulative dividends have been or contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set 

  

 4 








 
apart for such payment on the Series 1 Preferred Shares for all Dividend Periods terminating on or prior to the dividend payment date for such class or
series of Parity Shares. When dividends are not paid in full or a sum sufficient for such payment is not set apart, as aforesaid, all dividends declared upon Series 1 Preferred Shares and all dividends declared upon any other class or series of
Parity Shares shall be declared ratably in proportion to the respective amounts of dividends accumulated and unpaid on the Series 1 Preferred Shares and accumulated and unpaid on such Parity Shares. 
 (e) So long as any Series 1 Preferred Shares are outstanding, no dividends (other than dividends or distributions paid solely in shares of, or options,
warrants or rights to subscribe for or purchase shares of, Junior Shares) shall be declared or paid or set apart for payment or other distribution declared or made upon Junior Shares, nor shall any Junior Shares be redeemed, purchased or otherwise
acquired (other than a redemption, purchase or other acquisition of Common Shares made for purposes of any employee incentive or benefit plan of the Trust or any subsidiary) for any consideration (or any moneys be paid to or made available for a
sinking fund for the redemption of any such shares) by the Trust, directly or indirectly (except by conversion into or exchange for shares of Junior Shares), unless in each case (i) the full cumulative dividends on all outstanding Series 1
Preferred Shares and any other Parity Shares of the Trust shall have been or contemporaneously are declared and paid or declared and set apart for payment for all past Dividend Periods with respect to the Series 1 Preferred Shares and all past
dividend periods with respect to such Parity Shares and (ii) sufficient funds shall have been or contemporaneously are declared and paid or declared and set apart for payment of the dividend for the current Dividend Period with respect to the
Series 1 Preferred Shares and the current dividend period with respect to such Parity Shares. 
 (f) No dividends on Series 1 Preferred
Shares shall be authorized by the Board of Trustees or paid or set apart for payment by the Trust at such time as the terms and provisions of any agreement of the Trust, including any agreement relating to its indebtedness, prohibits such
authorization, payment or setting apart for payment or provides that such authorization, payment or setting apart for payment would constitute a breach thereof or a default thereunder, or if such authorization or payment shall be restricted or
prohibited by law. 
 (5) Liquidation Preference. 
 (a) In the event of any liquidation, dissolution or winding up of the Trust, whether voluntary or involuntary, before any payment or distribution of the assets of the Trust (whether capital or surplus) shall be made
to or set apart for the holders of Junior Shares, the holders of the Series 1 Preferred Shares shall be entitled to receive the Liquidation Price per share of Series 1 Preferred Shares plus an amount equal to all dividends (whether or not earned or
declared) accrued and unpaid thereon to the date of final distribution to such holders; but such holders shall not be entitled to any further payment. If, upon any liquidation, dissolution or winding up of the Trust, the assets of the Trust, or
proceeds thereof, distributable among the holders of the Series 1 Preferred Shares shall be insufficient to pay in full the preferential amount aforesaid and liquidating payments on any other shares of any class or series of Parity Shares, then such
assets, or the proceeds thereof, shall be distributed among the holders of the Series 1 Preferred Shares and any such other Parity Shares ratably in accordance with the respective amounts that would be payable on such Series 1 Preferred Shares and
any such other Parity Shares if all amounts payable thereon were paid in full. For the purposes of this Section 5: (i) a consolidation or merger of the Trust with one or more corporations, real estate investment trusts or other
entities, (ii) a sale, lease or transfer of all or substantially all of the Trust’s assets or (iii) a statutory share exchange shall not be deemed to be a liquidation, dissolution or winding up, voluntary or involuntary, of the Trust.

 (b) Subject to the rights of the holders of shares of any series or class of beneficial interest ranking on a parity with or prior to the
Series 1 Preferred Shares upon liquidation, dissolution or 

  

 5 








 
winding up, upon any liquidation, dissolution or winding up of the Trust, after payment shall have been made in full to the holders of the Series 1 Preferred
Shares, as provided in this Section 5, any other series or class of Junior Shares shall, subject to the respective terms and provisions (if any) applying thereto, be entitled to receive any and all assets remaining to be paid or
distributed, and the holders of the Series 1 Preferred Shares shall not be entitled to share therein. 
 (6) Voting Rights. The Series
1 Preferred Shares shall have no voting rights. 
 (7) Conversion. 
 (a) Holder Conversion Rights. 
 (1)
Subject to the limitations set forth in Section 7(a)(4), holders of Series 1 Preferred Shares shall have the right, at such holder’s option at any time after the Issue Date, to convert such shares into a number of fully paid and
nonassessable Common Shares determined by dividing (A) the product obtained by multiplying: (i) the number of Series 1 Preferred Shares being converted by (ii) the Liquidation Price; by (B) the Optional Conversion Price as in
effect immediately prior to the close of business on the Optional Conversion Date (defined below). All dividends payable on any Series 1 Preferred Shares that are converted shall cease to accrue on the Optional Conversion Date. 
 (2) Any holder of Series 1 Preferred Shares may exercise its optional right to convert to Common Shares by delivering an irrevocable written notice in
the form attached hereto as Exhibit A (the “Optional Conversion Notice”) by first class mail, postage prepaid, to the Trust at 1626 East Jefferson Street, Rockville, Maryland 20852, Attention: Chief Accounting Officer.

 (3) Within five (5) Business Days after receipt of an Optional Conversion Notice from a holder of Series 1 Preferred Shares, the
Trust shall establish a date for closing the conversion (“Optional Conversion Date”) which date shall not be more than fifteen (15) days after the date of the Optional Conversion Notice; provided, however, if the Trust receives the
Optional Conversion Notice more than seven (7) days after the date thereof, then the Trust shall be entitled to extend the Optional Conversion Date for the number of days after such seven-day period that the Trust received the Optional
Conversion Notice. Also within five (5) Business Days after receipt of an Optional Conversion Notice from a holder of Series 1 Preferred Shares, the Trust shall deliver instructions to the Transfer Agent to retire the Series 1 Preferred Shares
being converted, reflect such retirement on the books and records of the Trust, issue the number of Common Shares to be issued to the converting holder as a result of such conversion, and reflect such issuance on the books and records of the Trust,
in each case whether or not a certificate representing the Common Shares has been or will be issued and delivered to the converting holder as of such date. 
 (4) Except as may be approved by the Trust in writing in its sole and absolute discretion, the right for holders to convert Series 1 Preferred Shares to Common Shares shall be subject to the following restrictions and
limitations: (A) no conversion shall result in a holder and any related party, after giving effect to the conversion, owning Common Shares of the Trust in excess of the ownership limits specified in the Trust’s Declaration of Trust as in
effect on the Optional Conversion Date after taking into account the actual and constructive stock ownership rules of the Code and any other additional Common Shares of the Trust which such holder has acquired or intends to acquire prior to the
closing of such conversion; (B) no holder of Series 1 Preferred Shares may effect a conversion for Series 1 Preferred Shares having an aggregate value (determined by multiplying the number of Series 1 Preferred Shares to be converted by the
Liquidation Price) of less than $50,000, or, if such holder holds less than $50,000 of Series 1 Preferred Shares, less than all of the Series 1 Preferred Shares held by such 

  

 6 








 
holder; (C) no holder may effect a conversion more than three (3) times during any consecutive twelve-month period; and (D) no holder may
effect a conversion within ninety (90) days following the closing of any public offering of Common Shares by the Trust. 
 (b) Trust
Conversion Rights. 
 (1) The Trust shall have the right, at any time and from time to time, after the Issue Date and after the Elevated
Price Level (defined below) has occurred, subject to the provisions of this Section 7(b), to convert all or any outstanding Series 1 Preferred Shares into a number of fully paid and nonassessable Common Shares determined by dividing
(A) the product obtained by multiplying: (i) the number of Series 1 Preferred Shares being converted by (ii) the Liquidation Price; by (B) the Optional Conversion Price as in effect immediately prior to the close of business on
the Mandatory Conversion Date (defined below). All dividends payable on any Series 1 Preferred Shares that are converted shall cease to accrue on the Mandatory Conversion Date. 
 (2) The “Elevated Price Level” shall mean any time at which the trailing 200 consecutive Trading Day average closing price of the Common
Shares as reported on the New York Stock Exchange (or if such securities are not listed or admitted for trading on the NYSE, on the principal national securities exchange on which such securities are listed or admitted, or if not listed or admitted
for trading on any national securities exchange, in the applicable securities market in which the securities are traded) is greater than the Mandatory Conversion Trigger Price; provided, however, that the first day of any such 200-Trading Day period
shall not be earlier than the Closing Date. 
 (3) The Trust shall exercise its election to convert Series 1 Preferred Shares by delivering
written notice in the form attached hereto as Exhibit B (the “Mandatory Conversion Notice”) by first class mail, postage prepaid, to each holder of record of Series 1 Preferred Shares to be converted at the addresses shown
on the Trust’s records on the date of the Mandatory Conversion Notice. The Trust shall establish a date for closing the conversion (“Mandatory Conversion Date”) which date shall not be more than fifteen (15) days after the date
of the Mandatory Conversion Notice. In addition to delivering the Mandatory Conversion Notice, the Trust shall also issue a press release containing the information in the Mandatory Conversion Notice, excepting any information that is personal to
particular holders, and shall publish such information on its website, provided, however, that failure to issue such press release or publish such information on the Trust’s website shall not act to prevent, delay or void any conversion
pursuant to this Section 7(b). If fewer than all the outstanding Series 1 Preferred Shares are to be converted pursuant to this Section 7(b), shares to be so converted shall be selected by the Trust by lot or pro rata (as
nearly as may be) or by any other method determined by the Trust in its sole discretion to be equitable. Notwithstanding the foregoing, the Trust shall not be entitled to deliver a Mandatory Conversion Notice unless: (i) the Elevated Price
Level shall have occurred no more than six (6) months prior to the date of the Mandatory Conversion Notice; and (ii) the Current Market Price of the Common Shares on the date of the Mandatory Conversion Notice shall be equal to or exceed
the Mandatory Conversion Price. The Trust shall deliver instructions to the Transfer Agent to retire the Series 1 Preferred Shares being converted, reflect such retirement on the books and records of the Trust, issue the number of Common Shares
to be issued to the converting holder as a result of such conversion, and reflect such issuance on the books and records of the Trust, in each case whether or not a certificate representing the Common Shares has been, or will be, issued and
delivered to the converting holder as of such date. 
 (c) Conversion Mechanics. 
 (1) Generally, all Common Shares issued on conversion will be issued in the same name as the name in which the Series 1 Preferred Shares are issued. If
Common Shares are to be 

  

 7 








 
issued in any other name, then the holder or such holder’s duly authorized attorney shall deliver to the office of the Trust instruments of transfer, in
form satisfactory to the Trust, duly executed by the holder or such holder’s duly authorized attorney, and an amount sufficient to pay any transfer or similar tax (or evidence reasonably satisfactory to the Trust demonstrating that such taxes
have been paid). 
 (2) Holders of Series 1 Preferred Shares at the close of business on a record date for any dividend payment shall be
entitled to receive the distribution payable on such shares on the corresponding Dividend Payment Date notwithstanding the conversion thereof following such dividend payment record date and prior to such Dividend Payment Date. However, Series 1
Preferred Shares surrendered for conversion during the period between the close of business on any dividend payment record date and the opening of business on the corresponding Dividend Payment Date must be accompanied by payment of an amount equal
to the distribution payable on such shares on such Dividend Payment Date. A holder of Series 1 Preferred Shares on a dividend payment record date who (or whose transferee) tenders any such shares for conversion into Common Shares on such Dividend
Payment Date will receive the dividend payable by the Trust on such Series 1 Preferred Shares on such date, and the converting holder need not include payment of the amount of such dividend upon surrender of Series 1 Preferred Shares for conversion.
Except as provided above, the Trust shall make no payment or allowance for unpaid dividends, whether or not in arrears, on converted shares or for distributions on the Common Shares issued upon such conversion. 
 (3) As promptly as practicable after the retirement of Series 1 Preferred Shares, as aforesaid, the Trust shall issue and shall deliver to such holder
any amounts payable to such holder as a result of any fractional interest in respect of a Common Share arising upon such conversion as provided in Section 7(d). 
 (4) A conversion shall be deemed to have been effected: (A) in the case of optional conversion pursuant to Section 7(a), immediately
prior to the close of business on the Optional Conversion Date set by the Trust; and (B) in the case of a mandatory conversion pursuant to Section 7(b), immediately prior to the close of business on the Mandatory Conversion Date, in
each case provided that the provisions of Section 7(a) and Section 7(b), as applicable, have been satisfied; and in each case, the Person or Persons in whose name or names the Common Shares shall be issuable upon such
conversion shall be deemed to have become the holder or holders of record of the shares represented thereby at such time on such date, and such conversion shall be at the Mandatory Conversion Price or Optional Conversion Price, as applicable, in
effect at such time and on such date unless the share transfer books of the Trust shall be closed on that date, in which event such Person or Persons shall be deemed to have become such holder or holders of record at the close of business on the
next succeeding day on which such share transfer books are open, but such conversion shall be at the Mandatory Conversion Price or Optional Conversion Price, as applicable, in effect on the Optional Conversion Date or the Mandatory Conversion Date,
as applicable. 
 (d) Fractional Shares. No fractional shares or scrip representing fractions of Common Shares shall be issued upon
conversion of Series 1 Preferred Shares. Instead of any fractional interest in a Common Share that would otherwise be deliverable upon the conversion of a Series 1 Preferred Share, the Trust shall pay to the holder of such share an amount in cash
based upon the Current Market Price of Common Shares on the Business Day immediately preceding the date of conversion. If more than one Series 1 Preferred Share shall be surrendered for conversion at one time by the same holder, the number of full
Common Shares issuable upon conversion thereof shall be computed on the basis of the aggregate number of Series 1 Preferred Shares so surrendered. 
 (e) Adjustment of Conversion Price. The Conversion Price shall be adjusted from time to time as follows (for purposes of this Section 7, “Mandatory Conversion Trigger Price” shall refer 

  

 8 








 
to the Initial Mandatory Conversion Trigger Price as adjusted from time to time pursuant to this Section 7(e), and “Optional Conversion
Price” shall refer to the Initial Optional Conversion Price, as adjusted from time to time pursuant to this Section 7(e), and “Conversion Price” shall refer to the Mandatory Conversion Trigger Price or the Optional
Conversion Price, as applicable): 
 (1) If the Trust shall after the Issue Date: (A) pay or make a distribution on its Common Shares in
Common Shares; (B) subdivide its outstanding Common Shares into a greater number of shares; (C) combine its outstanding Common Shares into a smaller number of shares; or (D) issue any shares of beneficial interest by reclassification
of its Common Shares, then in each such case the Conversion Price in effect at the opening of business on the day following the date fixed for the determination of shareholders entitled to receive such distribution or at the opening of business on
the day following the day on which such subdivision, combination or reclassification becomes effective, as the case may be, shall be adjusted so that the holder of any Series 1 Preferred Shares thereafter surrendered for conversion shall be entitled
to receive the number of Common Shares that such holder would have owned or have been entitled to receive after the happening of any of the events described above had such shares been converted immediately prior to the record date in the case of a
distribution or the effective date in the case of a subdivision, combination or reclassification. An adjustment made pursuant to this Section 7(e)(1) shall become effective immediately after the opening of business on the day next
following the record date (except as provided in Section 7(i) below) in the case of a dividend and shall become effective immediately after the opening of business on the day next following the effective date in the case of a
subdivision, combination or reclassification. Such adjustment(s) shall be made successively whenever any of the events listed above shall occur. 
 (2) If the Trust shall issue after the Issue Date rights, options or warrants to all holders of Common Shares entitling them (for a period expiring within 45 days after the record date mentioned below) to subscribe for or purchase
Common Shares at a price per share less than the Fair Market Value per Common Share on the record date for the determination of shareholders entitled to receive such rights, options or warrants, then the Conversion Price in effect at the opening of
business on the day next following such record date shall be adjusted to equal the price determined by multiplying: (A) the Conversion Price in effect immediately prior to the opening of business on the day following the date fixed for such
determination by (B) a fraction, the numerator of which shall be the sum of: (1) the number of Common Shares outstanding on the close of business on the date fixed for such determination and (2) the number of Common Shares that the
aggregate proceeds to the Trust from the exercise of such rights, options or warrants for Common Shares would purchase at such Fair Market Value, and the denominator of which shall be the sum of: (X) the number of Common Shares outstanding on
the close of business on the date fixed for such determination and (Y) the number of additional Common Shares offered for subscription or purchase pursuant to such rights, options or warrants. Such adjustments shall be made successively
whenever any such rights, options or warrants are issued, and shall become effective immediately after the opening of business on the day next following such record date (except as provided in Section 7(i) below). In determining whether
any rights, options or warrants entitle the holders of Common Shares to subscribe for or purchase Common Shares at less than the Fair Market Value, there shall be taken into account any consideration received by the Trust upon issuance and upon
exercise of such rights, options or warrants, the value of such consideration, if other than cash, to be determined by the Chief Executive Officer of the Trust or the Board of Trustees. 
 (3) No adjustment in the Conversion Price shall be required unless such adjustment would require a cumulative increase or decrease of at least 1% in
such price; provided, however, that any adjustments that by reason of this Section 7(e)(3) are not required to be made shall be carried forward and taken into account in any subsequent adjustment until made. Notwithstanding any other
provisions of this Section 7, the Trust shall not be required to make any adjustment of the Conversion Price for the issuance of any Common Shares pursuant to any plan providing for the 

  

 9 








 
reinvestment of distributions or interest payable on securities of the Trust and the investment of additional optional amounts in Common Shares under such
plan. All calculations under this Section 7 shall be made to the nearest cent (with $.005 being rounded upward) or to the nearest one-ten-thousandth of a share (with .0005 of a share being rounded upward), as the case may be. 

(f) Transactions. If the Trust shall be a party to any transaction (including without limitation a merger, consolidation, statutory share
exchange, self tender offer for all or substantially all of the Common Shares, sale of all or substantially all of the Trust’s assets or recapitalization of the Common Shares and excluding any transaction as to which Section 7(e)
applied) (each of the foregoing being referred to herein as a “Transaction”), in each case as a result of which Common Shares shall be converted into the right to receive shares, stock, securities or other property (including cash or any
combination thereof), each Series 1 Preferred Share which is not converted into the right to receive shares, stock, securities or other property in connection with such Transaction shall thereafter be convertible into the kind and amount of shares,
stock, securities and other property (including cash or any combination thereof) receivable upon the consummation of such Transaction by a holder of that number of Common Shares into which one Series 1 Preferred Share was convertible immediately
prior to such Transaction, assuming such holder of Common Shares (1) is not a Person with which the Trust consolidated or into which the Trust merged or which merged into the Trust or to which such sale or transfer was made, as the case may be
(a “Constituent Person”), or an affiliate of a Constituent Person and (2) failed to exercise his rights of election, if any, as to the kind or amount of shares, stock, securities and other property (including cash) receivable upon
such Transaction (each a “Non-Electing Share”) (provided that if the kind or amount of shares, stock, securities and other property (including cash) receivable upon such Transaction by each Non-Electing Share is not the same for each
Non-Electing Share, then the kind and amount of shares, stock, securities and other property (including cash) receivable upon such Transaction for each Non-Electing Share shall be deemed to be the kind and amount so receivable per share by a
plurality of the Non-Electing Shares). The Trust shall not be a party to any Transaction unless the terms of such Transaction are consistent with the provisions of this Section 7(f), and it shall not consent or agree to the occurrence of
any Transaction until the Trust has entered into an agreement with the successor or purchasing entity, as the case may be, for the benefit of the holders of the Series 1 Preferred Shares that will require such successor or purchasing entity, as the
case may be, to make provision in its certificate or articles of incorporation or other constituent documents to the end that the provisions of this Section 7(f) shall thereafter correspondingly be made applicable, as nearly as may
reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable upon conversion of the Series 1 Preferred Shares. The provisions of this Section 7(f) shall similarly apply to successive
Transactions. 
 (g) If: 
 (1)
the Trust shall authorize the granting to all holders of the Common Shares of rights, options or warrants to subscribe for or purchase any shares of any class or any other rights, options or warrants; or 
 (2) there shall be any reclassifications of the Common Shares (other than an event to which Section 7(e)(1) applied) or any consolidation or
merger to which the Trust is a party and for which approval of any shareholders of the Trust is required, or a statutory share exchange involving the conversion or exchange of Common Shares into securities or other property, or a self tender offer
by the Trust for all or substantially all of its outstanding Common Shares, or the sale or transfer of all or substantially all of the assets of the Trust and for which approval of any stockholder of the Trust is required; or 
  

 10 








 (3) there shall occur the voluntary or involuntary liquidation, dissolution or winding up of the Trust,

 then the Trust shall cause to be filed with the Transfer Agent and shall cause to be mailed to the holders of the Series 1 Preferred Shares at their
addresses as shown on the share records of the Trust, as promptly as possible, but at least fifteen (15) days prior to the applicable date hereinafter specified, a notice stating: (A) the date on which a record is to be taken for the
purpose of such grant of rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Shares of record to be entitled to such grant of rights, options or warrants are to be determined, provided,
however, that no such notification need be made in respect of a record or determination date for a grant of rights unless the corresponding adjustment in the Conversion Price would be an increase or decrease of at least 1%; or (B) the date on
which such reclassification, consolidation, merger, statutory share exchange, self tender offer, sale, transfer, liquidation, dissolution or winding up is expected to become effective, and the date as of which it is expected that holders of Common
Shares of record shall be entitled to exchange their Common Shares for securities or other property, if any, deliverable upon such reclassification, consolidation, merger, statutory share exchange, self tender offer, sale, transfer, liquidation,
dissolution or winding up. Failure to give or receive such notice or any defect therein shall not affect the legality or validity of the proceedings described in this Section 7. 
 (h) Notification of Adjustment. Whenever the Conversion Price is adjusted as herein provided, the Trust shall promptly file with the Transfer
Agent an officer’s certificate setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment, which certificate shall be conclusive evidence of the correctness of such
adjustment absent manifest error. 
 (i) In any case in which Section 7(c) provides that an adjustment shall become effective on
the date next following the record date for an event, the Trust may defer until the occurrence of such event: (A) issuing to the holder of any Series 1 Preferred Shares converted after such record date and before the occurrence of such event
the additional Common Shares issuable upon such conversion by reason of the adjustment required by such event over and above the Common Shares issuable upon such conversion before giving effect to such adjustment; and (B) fractionalizing any
Series 1 Preferred Share and/or paying to such holder any amount of cash in lieu of any fraction pursuant to Section 7(d). 
 (j)
There shall be no adjustment of the Conversion Price in case of the issuance of any shares of beneficial interest of the Trust in a reorganization, acquisition or other similar transaction except as specifically set forth in this
Section 7. If any action or transaction would require adjustment of the Conversion Price pursuant to more than one subsection of this Section 7, only one adjustment shall be made to the Conversion Price, and such adjustment
shall be the amount of adjustment that has the highest absolute value. 
 (k) If the Trust shall take any action affecting the Common Shares,
other than action described in this Section 7, that in the opinion of the Board of Trustees would materially adversely affect the conversion rights of the holders of the Series 1 Preferred Shares, the Conversion Price may be adjusted, to
the extent permitted by law, in such manner, if any, and at such time, as the Board of Trustees, in its sole discretion, may determine to be equitable in the circumstances. 
 (l) The Trust covenants that it will at all times reserve and keep available, free from preemptive rights, out of the aggregate of its authorized but
unissued Common Shares, for the purpose of effecting conversion of the Series 1 Preferred Shares, the maximum number of Common Shares deliverable upon the conversion of all outstanding Series 1 Preferred Shares not theretofore converted. For
purposes of this Section 7(l), the number of Common Shares that shall be deliverable upon the 

  

 11 








 
conversion of all outstanding Series 1 Preferred Shares shall be computed as if at the time of computation all such outstanding shares were held by a single
holder. The Trust covenants that any Common Shares issued upon conversion of the Series 1 Preferred Shares shall be validly issued, fully paid and nonassessable. Before taking any action that would cause an adjustment reducing the Conversion Price
below the then par value of the Common Shares deliverable upon conversion of the Series 1 Preferred Shares, the Trust will take any action that, in the opinion of its counsel, may be necessary in order that the Company may validly and legally issue
fully paid and nonassessable Common Shares at such adjusted Conversion Price. The Trust shall endeavor to list the Common Shares required to be delivered upon conversion of the Series 1 Preferred Shares, prior to such delivery, upon each national
securities exchange, if any, upon which the outstanding Common Shares are listed at the time of such delivery. 
 (m) The Trust will pay any
and all documentary stamp or similar issue or transfer taxes payable in respect of the issue or delivery of Common Shares or other securities or property on conversion of the Series 1 Preferred Shares pursuant hereto; provided, however, that the
Trust shall not be required to pay any tax that may be payable in respect of any transfer involved in the issue or delivery of Common Shares or other securities or property in a name other than that of the holder of the Series 1 Preferred Shares to
be converted, and no such issue or delivery shall be made unless and until the Person requesting such issue or delivery has paid to the Trust the amount of any such tax or has established, to the reasonable satisfaction of the Trust, that such tax
has been paid. 
 (8) Application of Article VII. The designations, powers, preferences and relative participating, optional or other
special rights, and the qualifications, limitations or restrictions, of the Series 1 Preferred Shares shall be subject in all cases to the provisions of Article VII of the Declaration of Trust regarding limitations on beneficial
ownership of the Trust’s equity securities. 
 (9) Shares to be Retired. All Series 1 Preferred Shares which shall have been
issued and reacquired in any manner by the Trust shall be restored to the status of authorized but unissued Preferred Shares, without designation as to class or series. 
 (10) Record Holders. The Trust and the Transfer Agent may deem and treat the record holder of any Series 1 Preferred Shares as the true and lawful owner thereof for all purposes, and neither the Trust nor the
Transfer Agent shall be affected by any notice to the contrary. 
 (11) Sinking Fund. The Series 1 Preferred Shares shall not be
entitled to the benefits of any retirement or sinking fund. 
 (12) Certificates; Registration. The Series 1 Preferred Shares shall
not be certificated at any time. Upon issuance, the Series 1 Preferred Shares shall be registered at the Transfer Agent in the names of the holders thereof, as applicable. The holders of the Series 1 Preferred Shares may not transfer the Series 1
Preferred Shares to brokerage accounts to be held in “street name” or otherwise at any time. 
 SECOND: The Series 1
Preferred Shares have been classified and designated by the Board under the authority contained in the Declaration of Trust. 
 THIRD:
These Articles Supplementary have been approved by the Board in the manner and by the vote required by law. 
 FOURTH: These Articles
Supplementary shall be effective at the time the State Department of Assessments and Taxation of Maryland accepts these Articles Supplementary for record.

act of the Trust and, as to all matters or facts required to be verified under oath, the undersigned President acknowledges that to the best of his knowledge, information and belief, these matters and facts are true in all material respects and that
