 EXHIBIT G 
 DESIGNATION OF TERMS AND CONDITIONS OF SERIES A 
 PREFERRED PARTNERSHIP
UNITS 
 A. Designation and Number. A series of Preferred Partnership Units, designated as Series A Preferred Partnership Units,
is hereby established. The number of Series A Preferred Partnership Units shall be 8,050,000. 
 B. Rank. The Series A Preferred
Partnership Units will, with respect to rights to receive distributions and to participate in distributions or payments upon liquidation, dissolution or winding up of the Partnership, rank (a) senior to the Common Partnership Units and any
other Partnership Units of the Company, now or hereafter issued and outstanding, the terms of which provide that such Partnership Units rank, as to distributions and upon liquidation, dissolution or winding up of the Partnership, junior to such
Series A Preferred Partnership Units (“Junior Units”), (b) on a parity with any other Partnership Units of the Partnership, now or hereafter issued and outstanding, other than Partnership Units referred to in clauses
(a) and (c) (“Parity Units”); and (c) junior to all Partnership Units of the Partnership the terms of which specifically provide that such Partnership Units rank senior to the Series A Preferred Partnership
Units. 
 C. Distributions. 

(i) Subject to the rights of holders of any Preferred Partnership Units ranking senior to the Series A Preferred Partnership Units
as to the payment of distributions, the Company, in its capacity as the holder of the then outstanding Series A Preferred Partnership Units, shall be entitled to receive, when, as and if authorized by the Company, out of funds legally available for
payment of distributions, cumulative cash distributions at the rate of 7.875% per annum of the $25 liquidation preference of each Series A Preferred Partnership Unit (equivalent to $1.96875 per annum per Series A Preferred Partnership Unit);
provided, however, that if following a “Change of Control” of the Company (as defined in the Series A Articles Supplementary), the Series A Preferred Stock is not listed on the NYSE or quoted on NASDAQ (or listed or
quoted on a successor exchange or quotation system), holders of the then outstanding shares of Series A Preferred Partnership Units will be entitled to receive, when, as and if authorized by the Company and declared by the Company, out of funds
legally available for the payment of distributions, cumulative cash distributions from, and including, the first date on which both the Change of Control has occurred and the Series A Preferred Stock is not so listed or quoted, at the rate of
11.875% per annum of the $25 liquidation preference of each Series A Preferred Partnership Unit (equivalent to $2.96875 per annum per Series A Preferred Partnership Unit), for as long as the Series A Preferred Stock is not so listed on the NYSE
or quoted on NASDAQ (or listed or quoted on a successor exchange or quotation system) (the “Special Distribution Rate”). 
 (ii) Distributions on each outstanding Series A Preferred Partnership Unit shall be cumulative from and including the date of original issuance or, with respect to the Special Distribution Rate, from, and
including, the first date on which both a Change of Control has occurred and the Series A Preferred Stock is not listed on the NYSE or quoted on NASDAQ (or listed or quoted on a successor exchange or quotation system), and shall be payable
(i) for the period from October 13, 2010 to January 15, 2011 on January 15, 2011, and (ii) for each quarterly distribution period thereafter, quarterly in equal amounts in arrears on the 15th of each January, April, July and
October, commencing on April 15th, 2011 (each such day being hereinafter called a “Series A Distribution Payment Date”) at the then applicable annual rate; provided, however, that if any Series A Distribution
Payment Date falls on any day other than a Business Day (as defined in the Series A Articles Supplementary), the distribution which would otherwise have been payable on such Series A Distribution Payment Date may be paid on the next succeeding
Business Day with the same force and effect as if paid on such Series A Distribution Payment 
  

 5 








 
Date, and no interest or other sums shall accrue on the amount so payable from such Series A Distribution Payment Date to such next succeeding Business Day. Each distribution is payable to
holders of record as they appear on the Partnership Unit records of the Partnership at the close of business on the record date, not exceeding 30 days preceding the applicable Series A Distribution Payment Date, as shall be fixed by the
Company. Distributions shall accumulate from the most recent Series A Distribution Payment Date to which distribution have been paid, whether or not there shall be funds legally available for the payment of such distributions, whether the
Partnership has earnings or whether such distributions are authorized. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on the Series A Preferred Partnership Units that may be in
arrears. Holders of the Series A Preferred Partnership Units shall not be entitled to any distributions, whether payable in cash, property or stock, in excess of full cumulative distributions, as herein provided, on the Series A Preferred
Partnership Units. Distributions payable on the Series A Preferred Partnership Units for any period greater or less than a full distribution period will be computed on the basis of a 360-day year consisting of twelve 30-day months. Distributions
payable on the Series A Preferred Partnership Units for each full distribution period will be computed by dividing the applicable annual distribution rate by four. After full cumulative distributions on the Series A Preferred Partnership Units have
been paid or declared and funds therefor set aside for payment with respect to a distribution period, the holders of Series A Preferred Partnership Units will not be entitled to any further distributions with respect to that distribution period.

 (iii) No distributions on the Series A Preferred Partnership Units shall be authorized and declared by the Company or paid or
set apart for payment by the Company at such time as the terms and provisions of any agreement of the Company, including any agreement relating to its indebtedness, prohibits such declaration, payment or setting apart for payment or provides that
such declaration, payment or setting apart for payment would constitute a breach thereof, or a default thereunder, or if such declaration or payment shall be restricted or prohibited by law. 

(iv) So long as any Series A Preferred Partnership Units are outstanding, no distributions, except as described in the immediately
following sentence, shall be authorized and declared or paid or set apart for payment on any series or class or classes of Parity Units for any period unless full cumulative distributions have been declared and paid or are contemporaneously declared
and paid or declared and a sum sufficient for the payment thereof set apart for such payment on the Series A Preferred Partnership Units for all prior distribution periods. When distributions are not paid in full or a sum sufficient for such payment
is not set apart, as aforesaid, all distributions authorized and declared upon the Series A Preferred Partnership Units and all distributions authorized and declared upon any other series or class or classes of Parity Units shall be authorized and
declared ratably in proportion to the respective amounts of distributions accumulated and unpaid on the Series A Preferred Partnership Units and such Parity Units. 
 (v) So long as any Series A Preferred Partnership Units are outstanding, no distributions (other than distributions paid solely in Junior Units of, or in options, warrants or rights to subscribe for or
purchase, Junior Units) shall be authorized and declared or paid or set apart for payment or other distribution authorized and declared or made upon Junior Units, nor shall any Junior Units be redeemed, purchased or otherwise acquired (other than a
redemption, purchase or other acquisition of Partnership Units made for purposes of and in compliance with requirements of an employee incentive or benefit plan of the Company or any subsidiary, or a conversion into or exchange for Junior Units or
redemptions for the purpose of preserving the Company’s qualification as a REIT (as defined in the Charter), or redemptions of Partnership Units pursuant to Article 8 of the Partnership Agreement), for any consideration (or any monies to be
paid to or made available for a sinking fund for the redemption of any such units) by the Company, directly 
  

 6 








 
or indirectly (except by conversion into or exchange for Junior Units), unless in each case full cumulative distributions on all outstanding shares of Series A Preferred Partnership Units and any
Parity Units at the time such dividends are payable shall have been paid or set apart for payment for all past distribution periods with respect to the Series A Preferred Partnership Units and all past distribution periods with respect to such
Parity Units. 
 (vi) Any distribution payment made on the Series A Preferred Partnership Units shall first be credited against
the earliest accrued but unpaid distribution due with respect to such Units which remains payable. 
 (vii) Except as provided
herein, the Series A Preferred Partnership Units shall not be entitled to participate in the earnings or assets of the Partnership. 
 As used herein, the term “distribution” does not include distributions payable solely in units of Junior Units on Junior Units, or in options, warrants or rights to holders of Junior Units to
subscribe for or purchase any Junior Units. 
 D. Liquidation Preference. 

(i) In the event of any liquidation, dissolution or winding up of the Partnership, whether voluntary or involuntary, before any
payment or distribution of the assets of the Partnership shall be made to or set apart for the holders of Junior Units, the holders of the Series A Preferred Partnership Units shall be entitled to receive $25 per Unit (the “Liquidation
Preference”) plus an amount per Unit equal to all distributions (whether or not earned or declared) accumulated and unpaid thereon to, but not including, the date of final distribution to such holders; but such holders of the Series A
Preferred Partnership Units shall not be entitled to any further payment. If, upon any such liquidation, dissolution or winding up of the Partnership, the assets of the Partnership, or proceeds thereof, distributable among the holders of the Series
A Preferred Partnership Units shall be insufficient to pay in full the preferential amount aforesaid and liquidating payments on any other Parity Units, then such assets, or the proceeds thereof, shall be distributed among the holders of such Series
A Preferred Partnership Units and any such other Parity Units ratably in accordance with the respective amounts that would be payable on such Series A Preferred Partnership Units and any such other Parity Units if all amounts payable thereon were
paid in full. For the purposes of this Section D, none of (i) a consolidation or merger of the Partnership with one or more entities, (ii) a statutory Unit exchange or (iii) a sale or transfer of all or substantially all
of the Partnership’s assets shall be deemed to be a liquidation, dissolution or winding up, voluntary or involuntary, of the Partnership. 
 (ii) Subject to the rights of the holders of Parity Units, upon any liquidation, dissolution or winding up of the Partnership, after payment shall have been made in full to the holders of the Series
A Preferred Partnership Units, as provided in this Section D, any series or class or classes of Junior Units shall, subject to any respective terms and provisions applying thereto, be entitled to receive any and all assets remaining to
be paid or distributed, and the holders of the Series A Preferred Partnership Units shall not be entitled to share therein. 

E. Redemption. In connection with the redemption by the Company of any shares of Series A Preferred Stock in accordance with the provisions
of the Series A Articles Supplementary, the Partnership shall provide cash to the Company for such purpose which shall be equal to the redemption price (as set forth in the Series A Articles Supplementary), plus all plus any accumulated and unpaid
dividends on the Series A Preferred Stock (whether or not declared), to, but not including, the redemption date, and one Series A Preferred Partnership Unit shall be concurrently redeemed with respect to each share of Series A Preferred Stock so
redeemed by the 
  

 7 








 
Company. From and after the applicable redemption date, the Series A Preferred Partnership Units so redeemed shall no longer be outstanding and all rights hereunder, to distributions or
otherwise, with respect to such Series A Preferred Partnership Units shall cease. Any Series A Preferred Partnership Units so redeemed may be reissued to the Company at such time as the Company reissues a corresponding number of shares of Series A
Preferred Stock so redeemed or repurchased, in exchange for the contribution by the Company to the Partnership of the proceeds from such reissuance. 
 F. Voting Rights. Except as required by applicable law or the Partnership Agreement, the holder of the Series A Preferred Partnership Units, as such, shall have no voting rights. 

G. Conversion. The Series A Preferred Partnership Units are not convertible into or exchangeable for any other property or securities of the
Partnership. 
 H. Restriction on Ownership. The Series A Preferred Partnership Units shall be
owned and held solely by the Company. 
 I. Allocations. Allocations of the Partnership’s items of income, gain, loss and
deduction shall be allocated pro rata among holders of Series A Preferred Partnership Units in accordance with Article VI of the Partnership Agreement.
