Award.

(a)The Grantee is granted as of the Grant Date, the number of Award LTIP Units set forth on Schedule A which are subject to forfeiture as provided in this Section 3 and Section 4. It is a condition to the effectiveness of this Award that the Grantee execute and deliver an original or counterpart original of this Agreement and such other documents that the Company and/or the Partnership reasonably request in order to comply with all applicable legal requirements, including, without limitation, federal and state securities laws, and that the Grantee pays the Per Unit Purchase Price for each such Award LTIP Unit issued.

(b)The Award LTIP Units are subject to forfeiture during a maximum of a four-

year period based on a combination of (i) the extent to which the FFO Goal, as may be modified by the TSR Modifier, or the Objective Criteria Goals are achieved and (ii) the passage of four years or a shorter period in certain circumstances as provided in Section 4. Award LTIP Units may become Earned LTIP Units and Earned LTIP Units may become Vested LTIP Units in the amounts and upon the conditions set forth in this Section 3 and in Section 4, so long as the Continuous Service of the Grantee continues through the Scheduled Vesting Date, unless otherwise expressly set forth in this Agreement with respect to a Qualified Termination or Change of Control, or as determined by the Committee, in its sole and absolute discretion, as provided in Section 4(f).

(c)As soon as practicable following the Valuation Date, for the Award LTIP Units, as of the Valuation Date, the Committee, in its sole and absolute discretion, will determine:

(i)

if any; the extent to which the FFO Goal has been achieved;

(ii)

the extent to which the TSR Modifier is applicable, and its impact, if any

(iii)

the extent to which the Objective Criteria Goals have been achieved;

(iv)

using the payout matrix on Exhibit A, the number of Earned LTIP Units to which the Grantee is entitled, if any; and

(v)

If the number of Earned LTIP Units is smaller than the number of Award LTIP Units on the Valuation Date, then the Grantee, as of the Valuation Date, shall forfeit a number of Award LTIP Units equal to the difference, without payment of any consideration by the Partnership other than as provided in the last sentence of Section 5. Thereafter, the term LTIP Units, will refer only to the Earned LTIP Units, and neither the Grantee nor any of his or her successors, heirs, assigns, or personal representatives will have any further rights or interests in the Award LTIP Units that were so forfeited.

(d)Subject to Section 4 below, one hundred percent (100%) of the Earned LTIP Units shall become Vested LTIP Units on the Scheduled Vesting Date, provided that the Continuous Service of the Grantee continues through the Scheduled Vesting Date or the accelerated vesting date provided in Section 4, as applicable.

Termination of Grantee’s Employment; Death and Disability; Change of Control.

(a)If the Grantee’s Continuous Service terminates prior to the Scheduled Vesting Date, the provisions of Sections 4(b) through Section 4(f) shall govern the treatment of the Grantee’s Award LTIP Units exclusively, unless the Grantee's Service Agreement contains provisions that expressly refer to this Section 4(a) and provides that those provisions of the Service Agreement shall instead govern the treatment of the Grantee’s LTIP Units. In the event an entity of which the Grantee is an employee ceases to be a subsidiary or Affiliate of the Company, such action shall be deemed to be a termination of employment of the Grantee for purposes of this Agreement, unless the Grantee promptly thereafter becomes an employee of the Company or any of its Affiliates, provided that, the Committee or the Board, in its sole and absolute discretion, may make provision in such

circumstances for lapse of forfeiture restrictions and/or accelerated vesting of some or all of the Grantee’s Award LTIP Units or Earned LTIP Units, as the case may be, that have not previously been forfeited, effective immediately prior to such event. If a Change of Control occurs, Section 4(d) shall govern the treatment of the Grantee’s Award LTIP Units exclusively, notwithstanding the provisions of the Plan.

(b)In the event of termination of the Grantee’s Continuous Service before the Valuation Date by Grantee’s death or Disability (each a “Qualified Termination”), the Grantee will not forfeit the Award LTIP Units upon such termination, but the following provisions of this Section 4(b) shall modify the treatment of the Award LTIP Units:

(i)

the calculations provided in Section 3(c) shall be performed as of the Valuation Date as if the Qualified Termination had not occurred;

(ii)

the number of Earned LTIP Units calculated, pursuant to Section 3(c) shall be multiplied by the applicable Partial Service/Performance Factor(s) (with the resulting number(s) being rounded to the nearest whole LTIP Unit), and such adjusted number of Earned LTIP Units shall be deemed the Grantee’s Earned LTIP Units for all purposes under this Agreement; and

(iii)

the Grantee’s Earned LTIP Units as adjusted pursuant to Section 4(b)(ii) shall, as of the Valuation Date, become Vested LTIP Units and shall no longer be subject to forfeiture pursuant to Section 3(e).

(c)In the event of Qualified Termination after the Valuation Date, all Earned LTIP Units that have not become Vested LTIP Units shall, as of the date of such Qualified Termination, become Vested LTIP Units and no longer be subject to forfeiture; provided that, notwithstanding that the lapse of the Continuous Service requirement pursuant to this Section 4(b), the Grantee will not have the right to either (i) Transfer (as defined in Section 7) such Award LTIP Units, except by reason of the Grantee’s death, or (ii) request conversion of such Award LTIP Units under the Certificate of Designation until, in either case, such dates as of which his or her Earned LTIP Units would have become Vested LTIP Units pursuant to Section 3(d) absent a Qualified Termination or Section 4(d) below.

(d)If a Change of Control occurs prior to the Scheduled Vesting Date, the provisions of this Section 4(d) shall apply:

(i)If the Change of Control occurs prior to the Valuation Date, the calculation of the number of Earned LTIP Units as provided in Section 3(c) shall be performed as of the date of the Change of Control.

(ii)If, on or within 24 months after a Change of Control (A) described in clauses (i) or (ii) of the definition of Change of Control or (B) described in clause (iii) of the definition of Change of Control in connection with which the surviving or successor entity (or its parent entity) continues, assumes or replaces this Award in a manner that satisfies the conditions of Section 4(d)(iv) below (“Assumed”), the Grantee’s Continuous Service terminates as the result of either an involuntary termination for reasons other than Cause or a resignation for Good Reason, then to the extent the Grantee’s outstanding Award LTIP Units have not

already become Vested LTIP Units as of immediately prior to such termination, such Award LTIP Units shall become Vested LTIP Units as of the termination of Continuous Service and shall no longer be subject to forfeiture pursuant to the terms hereunder.

(iii)If this Award is not Assumed in connection with a Change of Control described in clause (iii) of the definition of Change of Control as contemplated by Section 4(d)(iv)(B), then to the extent the Grantee’s Earned LTIP Units have not already become Vested LTIP Units, such Earned LTIP Units shall become Vested LTIP Units as of the date of the Change of Control and shall no longer be subject to forfeiture pursuant to the terms hereunder. Unless the Committee, in its sole and absolute discretion, provides otherwise in connection with a Change of Control described in clause (iv) of the definition of Change of Control, the Grantee’s outstanding Award LTIP Units shall, to the extent they have not already become Vested LTIP Units, become Vested LTIP Units immediately prior to the consummation of the liquidation, dissolution or sale of assets and shall no longer be subject to forfeiture.

For purposes of this Section 4(d), this Award will be considered assumed if, in connection with the Change of Control, either (A) the contractual obligations represented by this Award are expressly assumed by the surviving or successor entity (or its parent entity) with appropriate adjustments to the number and type of securities subject to this Award that preserves the economic or financial value of this Award existing at the time the Change of Control occurs, or (B) the Grantee has received a comparable LTIP Unit award that preserves the economic or financial value of this Award existing at the time of the Change of Control and is subject to substantially similar terms and conditions as this Award.

(iv)Unless and until the Earned LTIP Units become Vested LTIP Units pursuant to Section 4(d)(ii) or Section 4(d)(iii), the Earned LTIP Units shall vest in accordance with Section 3(d).

(e)Notwithstanding the foregoing, in the event any payment required to be made hereunder after giving effect to this Section 4 constitutes “nonqualified deferred compensation” subject to Section 409A of the Code, then, to the extent the Grantee is a “specified employee” under Section 409A of the Code, such payment(s) will, to the extent necessary to avoid taxes under Section 409A(a)(2)(B)(i) of the Code, be delayed for the six-month period commencing on the Grantee’s “separation from service” (within the meaning of Section 409A of the Code) (or, if earlier, until the specified employee’s death) and shall instead be paid (as set forth in this Agreement) on the day immediately following the expiration of such six-month period or the specified employee’s death(without interest). Any payments of “nonqualified deferred compensation” under this Award payable more than six months following the Grantee’s “separation from service” will be paid at the time or times the payments are otherwise scheduled to be made.

(f)Unless the Grantee's Service Agreement provides otherwise, in the event of a termination of the Grantee’s Continuous Service other than a Qualified Termination or a termination described in Section 4(d)(ii), all Award LTIP Units or Earned LTIP Units, as the case may be, that have not become Vested LTIP Units as of the date of such termination shall, without payment of any consideration by the Partnership other than as provided in the last sentence of Section 5, automatically and without notice terminate, be forfeited and be and become null and void, and neither the Grantee nor any of his or her successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such Award LTIP Units or Earned LTIP Units, provided, however, that in the event the termination of Grantee’s Continuous Service is due to Grantee’s retirement at or after age 55, the Committee may determine, in its sole and absolute discretion, that all or any portion of the Award LTIP Units or the Earned LTIP Units that have not become Vested LTIP Units as of the date of such termination shall become Vested LTIP Units.

The obligations of the Company under this Agreement will be conditional on such payment or arrangements, and the Company and its Affiliates shall, to the extent permitted by law, have the right to deduct any such taxes from any payment otherwise due to the Grantee.
