(a)           Subject to the preferential rights of holders of any class or series of Senior Preferred Units of the Partnership, the holders of 5.500% Series C Participating Preferred Units shall be entitled to receive, when, as and if authorized by the General Partner and declared by the Partnership, out of funds of the Partnership legally available for payment of distributions, cumulative cash distributions at the applicable annual rate (the “Preferred Return”):

Distributions on the 5.500% Series C Participating Preferred Units shall accrue and be cumulative from (and including) the Original Issue Date and shall be payable quarterly, in equal amounts, in arrears, on the last day of each March, June, September and December of each year (each, a “Preferred Unit Distribution Payment Date”); provided, however, if any Preferred Unit Distribution Payment Date is not a business day, then the distribution which would otherwise have been payable on such Preferred Unit Distribution Payment Date may be paid on the next succeeding business day with the same force and effect as if paid on such Preferred Unit Distribution Payment Date, and no interest or additional distributions or other sums shall accrue on the amount so payable from such Preferred Unit Distribution Payment Date to such next succeeding business day.  “Business day” shall mean any day other than a Saturday or Sunday that is neither a legal holiday nor a day on which banking institutions in New York, New York are authorized or required to close.  A “distribution period” shall mean the period commencing from, and including, the Preferred Unit Distribution Payment Date to, but excluding, the next succeeding Preferred Unit Distribution Payment Date.  The initial distribution period shall be the period from, and including, the Original Issue Date to, but excluding, June 30, 2014 to holders of record of the 5.500% Series C Participating Preferred Units as of June 15, 2014.  The amount of any distribution payable on the 5.500% Series C Participating Preferred Units for any partial distribution period will be prorated and computed on the basis of twelve 30-day months and a 360-day year.  Distributions will be payable in arrears to holders of record of the 5.500% Series C Participating Preferred Units as they appear on the records of the Partnership at 5:00 P.M., New York time, on the applicable record date, which shall be the March 15, June 15, September 15, or December 15 immediately preceding the Preferred Unit Distribution Payment Date.  If such record date is not a Business Day, the record date shall be the immediately preceding Business Day (each, a “Distribution Record Date”).

(b)           No distributions on the 5.500% Series C Participating Preferred Units shall be authorized by the General Partner or declared, paid or set apart for payment by the Partnership at such time as the terms and provisions of any agreement of the General Partner or the Partnership, including any agreement relating to the indebtedness of any of them, prohibits such authorization, 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.

(c)           Notwithstanding anything to the contrary contained herein, distributions on the 5.500% Series C Participating Preferred Units will accrue whether or not the restrictions referred to in Section 5(b) exist, whether or not the Partnership has earnings, whether or not there are funds legally available for the payment of such distributions and whether or not such distributions are authorized or declared.  For the avoidance of doubt, no distributions on the 5.500% Series C Participating Preferred Units shall accrue on any HPA Amount prior to March 31, 2021.

3

(d)           Except as provided in Section 5(e) below, no distributions shall be declared and paid or 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 Class A Units, Class B Units, LTIP Units, Parity Preferred Units or Junior Preferred Units of the Partnership (other than a distribution paid in units of, or options, warrants or rights to subscribe for or purchase units of, Class A Units, Class B Units, LTIP Units or Junior Preferred Units) for any period, nor shall Class A Units, Class B Units, LTIP Units, Parity Preferred Units or Junior Preferred Units 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 any such units by the Partnership, directly or indirectly (except by conversion into or exchange for, or options, warrants or rights to purchase or subscribe for, Class A Units, Class B Units, LTIP Units or Junior Preferred Units, and except for purchases or exchanges pursuant to a purchase or exchange offer made on the same terms to all holders of 5.500% Series C Participating Preferred Units and all holders of Parity Preferred Units), unless full cumulative distributions on the 5.500% Series C Participating Preferred Units for all past distribution periods shall have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof is set apart for such payment.

(e)           When distributions are not paid in full (or a sum sufficient for such full payment is not so set apart) on the 5.500% Series C Participating Preferred Units and any Parity Preferred Units, all distributions declared on the 5.500% Series C Participating Preferred Units and any Parity Preferred Units shall be declared pro rata so that the amount of distributions declared per 5.500% Series C Participating Preferred Unit and such Parity Preferred Units shall in all cases bear to each other the same ratio that accrued distributions per 5.500% Series C Participating Preferred Unit and such Parity Preferred Units (which shall not include any accrual in respect of unpaid distributions on any Parity Preferred Units for prior distribution periods if such Parity Preferred Units do not have a cumulative distribution) bear to each other.  No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on 5.500% Series C Participating Preferred Units which may be in arrears.

(f)            Holders of 5.500% Series C Participating Preferred Units shall not be entitled to any distribution, whether payable in cash, property or units of the Partnership, in excess of full cumulative distributions on the 5.500% Series C Participating Preferred Units as provided above.  Any distribution made on the 5.500% Series C Participating Preferred Units shall first be credited against the earliest accrued but unpaid distributions due with respect to such units which remains payable.  Accrued but unpaid distributions on 5.500% Series C Participating Preferred Units will accumulate as of the Preferred Unit Distribution Payment Date on which they first become payable or on the date of redemption, as the case may be.

(g)           For the avoidance of doubt, in determining whether a distribution (other than upon voluntary or involuntary liquidation), redemption or other acquisition of the Partnership Units is permitted under Delaware law, no effect shall be given to the amounts that would be needed, if the Partnership were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of holders of Partnership Units whose preferential rights are superior to those receiving the distributio n.

6.             Liquidation Preference.

(a)           Upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Partnership, before any distribution or payment shall be made to the holders of any Class A Units, Class B Units, LTIP Units, or Junior Preferred Units, the holders of the 5.500% Series C Participating Preferred Units then outstanding shall be entitled to be paid, or have the Partnership declare and set apart for payment, out of the assets of the Partnership legally available for distribution to its Partners after payment or provision for payment of all debts and other liabilities of the Partnership and any liquidation preference owing in respect of any Senior Preferred Units, a liquidation preference in cash or property at fair market value, as determined by the General Partner, the sum of: (i) the Initial Liquidation Preference, (ii) the HPA Amount (if positive), and (iii) an amount per unit equal to any accrued and unpaid distributions to, but excluding, the date of payment or the date the amount for payment is set apart for payment (the “Final Liquidation Preference”).

(b)           If upon any such voluntary or involuntary liquidation, dissolution or winding up of the Partnership, the available assets of the Partnership are insufficient to pay the full amount of the Final Liquidation Preference on all outstanding 5.500% Series C Participating Preferred Units and the corresponding amounts payable on all outstanding Parity Preferred Units, then the holders of 5.500% Series C Participating Preferred Units and

4

Parity Preferred Units shall share ratably in any such distribution of assets in proportion to the full amount of the Final Liquidation Preference to which they would otherwise be respectively entitled.

(c)           Until March 31, 2021, the HPA Amount payable upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Partnership, shall be subject to a cap as provided in Section 6(e) of the Articles Supplementary.

(d)           Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, after payment shall have been made in full to the holders of the 5.500% Series C Participating Preferred Units and any Parity Preferred Units, any other series or class or classes of Junior Preferred Units shall be entitled to receive any and all assets remaining to be paid or distributed, and the holders of the 5.500% Series C Participating Preferred Units and any Parity Preferred Units shall not be entitled to share therein.

(e)           After payment of the full amount of the Final Liquidation Preference to which they are entitled, holders of 5.500% Series C Participating Preferred Units will have no right or claim to any of the remaining assets of the Partnership.

(f)            For the avoidance of doubt, the consolidation or merger of the Partnership with or into another entity, the merger of another entity with or into the Partnership, a statutory unit exchange by the Partnership or the sale, lease, transfer or conveyance of all or substantially all of the assets or business of the Partnership shall not be considered a liquidation, dissolution or winding up of the affairs of the Partnership.

(g)           Notice of liquidation, dissolution or winding up of the Partnership shall be consistent with the notice procedures set forth in Section 5(d) of the Articles Supplementary.

7.             Redemption.

(a)           The 5.500% Series C Participating Preferred Units are not redeemable except as otherwise provided in this Section 7.

iii.            Unless full cumulative distributions on all 5.500% Series C Participating Preferred Units shall have been or contemporaneously are declared and paid or declared and a sum

sufficient for the payment thereof set apart for payment for all past distribution periods, the Partnership shall not purchase or otherwise acquire directly or indirectly for any consideration, nor shall any monies be paid to or be made available for a sinking fund for the redemption of, any 5.500% Series C Participating Preferred Units (except by conversion into or exchange for, or options, warrants or rights to purchase or subscribe for Class A Units, Class B Units, LTIP Units or Junior Preferred Units of the Partnership); provided, however, that the foregoing shall not prevent the redemption or purchase of 5.500% Series C Participating Preferred Units by the Partnership in order to ensure that the General Partner remains qualified as a REIT for federal income tax purposes, or the purchase or acquisition of 5.500% Series C Participating Preferred Units pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding 5.500% Series C Participating Preferred Units.

iv.           Immediately prior to any redemption of 5.500% Series C Participating Preferred Units, the Partnership shall pay, in cash, any accrued and unpaid distributions on the 5.500% Series C Participating Preferred Units to, but excluding, the Redemption Date, unless a Redemption Date falls after a Distribution Record Date and prior to the corresponding Preferred Unit Distribution Payment Date, in which case each holder of 5.500% Series C Participating Preferred Units at the close of business on such Distribution Record Date shall be entitled to the distribution payable on such units on the corresponding Preferred Unit Distribution Payment Date (including any accrued and unpaid distributions for prior distribution periods) notwithstanding the redemption of such units before such Preferred Unit Distribution Payment Date.  Except as provided above, the Partnership will make no payment or allowance for unpaid distributions, whether or not in arrears, on 5.500% Series C Participating Preferred Units for which a notice of redemption has been given.

v.              Notice of redemption of the 5.500% Series C Participating Preferred Units shall be consistent with the notice procedures set forth in Section 7(a)(iii)(A) of the Articles Supplementary.

If a redemption date falls after a Distribution Record Date for a 5.500% Series C Participating Preferred Unit distribution payment and prior to the corresponding Preferred Unit Distribution Payment Date, then each holder of the 5.500% Series C Participating Preferred Units at the close of business on such Distribution Record Date shall be entitled to the distribution payable on such 5.500% Series C Participating Preferred Units on the corresponding Preferred Unit Distribution Payment Date notwithstanding the redemption of such 5.500% Series C Participating Preferred Units before such Preferred Unit Distribution Payment Date. Except as provided above, the Partnership shall make no payment or allowance for unpaid distributions, whether or not in arrears, on any 5.500% Series C Participating Preferred Units called for redemption.

iv.           If full cumulative distributions on the 5.500% Series C Participating Preferred Units and any other series or class or classes of Parity Preferred Units have not been paid or declared and set apart for payment, except as otherwise permitted under the Partnership Agreement, the Partnership may not purchase, redeem or otherwise acquire 5.500% Series C Participating Preferred Units or any Parity Preferred Units other than in exchange for Parity Preferred Units.

v.              On and after the date fixed for redemption, distributions shall cease to accrue on the 5.500% Series C Participating Preferred Units called for redemption (except that, in the case of a redemption date after a Distribution Record Date and prior to the related Preferred Unit Distribution Payment Date, holders of 5.500% Series C Participating Preferred Units on the applicable Distribution Record Date will be entitled on such

8

Preferred Unit Distribution Payment Date to receive the distribution payable on such shares on the corresponding Preferred Unit Distribution Payment Date), such shares shall no longer be deemed to be outstanding and all rights of the holders of such shares as holders of 5.500% Series C Participating Preferred Units shall cease except the right to receive the cash payable upon such redemption, without interest from the date of such redemption.

8.                                      Voting Rights.  Holders of the 5.500% Series C Participating Preferred Units will not have any voting rights.

(c)                                  Conversion by the Partnership.

i.                  After March 31, 2018, if and when AH4R exercises its option to convert 5.500% Series C Participating Preferred Shares as provided in Section 11(a) of the Articles Supplementary, the Partnership will convert all (no partial conversions are permitted) of the 5.500% Series C Participating Preferred Units into Class A Units in the Partnership in accordance with this Section 9.

ii.               If such one-time conversion occurs after March 31, 2018 but before March 31, 2021, the formula for determining the conversion ratio per 5.500% Series C Participating Preferred Unit shall be equal to: (A) the sum of (1) the Initial Liquidation Preference, (2) the HPA Amount for the relevant period (if positive), and (3) any accrued and unpaid distributions thereon to, but excluding, the 4th business day following the notice of conversion (the “Conversion Date”), divided by (B) the VWAP on the date the notice of conversion is issued.

iii.            If such one-time conversion occurs at any time on or after March 31, 2021, the Partnership will convert all but not less than all (no partial redemptions are permitted) of the 5.500% Series C Participating Preferred Units using a conversion formula equal to: (A) the Adjusted Value, plus any accrued and unpaid distributions thereon to, but excluding, the Conversion Date, divided by (B) the VWAP on the date the notice of conversion is issued.

iv.           The foregoing shall not prevent the conversion of 5.500% Series C Participating Preferred Units by the Partnership in order to ensure that the General Partner remains qualified as a REIT for federal income tax purposes.

v.              No fractional Class A Units shall be issued upon conversion of the 5.500% Series C Participating Preferred Units.  In lieu of fractional units, holders of the 5.500% Series C Participating Preferred Units shall be entitled to receive the cash value of such fractional units based on the applicable per share VWAP.

(d)                                 Conversion Upon a Change of Control.

i.                  Upon the occurrence of a Change of Control, each holder of the 5.500% Series C Participating Preferred Units shall have the right (the “Change of Control Conversion Right”), subject to the Special Redemption Right of the Partnership, to convert some or

9
