(a) The Grantee is granted as of the Award Date, the number of Award LTIP Units set forth on Schedule A which are subject to forfeiture provided in this Section 3 and Section 4. The Award LTIP Units will be forfeited unless within ten (10) business days from the Award Date the Grantee executes and delivers a fully executed copy 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 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 five-year period based on a combination of (i) the extent to which the Absolute TSR Goal and the Relative TSR Goals are achieved and (ii) the passage of five years or a shorter period in certain circumstances as provided herein 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, provided that, except as otherwise expressly set forth in this Agreement, the Continuous Service of the Grantee continues through and on each applicable vesting date.

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

(iv) the calculation of the Partial Service Factor, if applicable to the Grantee.

If the number of Earned LTIP Units is smaller than the number of Award LTIP Units, 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 thereafter have any further rights or interests in the Award LTIP Units that were so forfeited.

(d) The Earned LTIP Units shall become Vested LTIP Units in the following amounts and at the following times, provided that the Continuous Service of the Grantee continues through and on the applicable vesting date or the accelerated vesting date provided in Section 4, as applicable:

(i) fifty percent (50%) of the Earned LTIP Units shall become Vested LTIP Units on January 1, 2016; and

(ii) fifty percent (50%) of the Earned LTIP Units shall become Vested LTIP Units on January 1, 2017.

(e) Except as otherwise provided under Section 4, upon termination of Continuous Service before the applicable vesting date, any Earned LTIP Units that have not become Vested LTIP Units pursuant to Section 3(d) shall, without payment of any consideration by the Partnership other than as provided in the last sentence of Section 5, automatically and without notice 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 Earned LTIP Units.

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

(a) If the Grantee ceases to be an employee of the Company or any of its affiliates, the provisions of Sections 4(b) through Section 4(f) shall govern the treatment of the Grantee's Award LTIP Units exclusively, unless an Employment Agreement contains provisions that expressly refer to this Section 4(a) and provides that those provisions of the Employment 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 and Earned LTIP Units 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 Partial Service Factor (with the resulting number being rounded to the nearest whole LTIP Unit or, in the case of 0.5 of a unit, up to the next whole unit), and such adjusted number of 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 previously been forfeited pursuant to the calculations set forth in Section 3(c) shall, as of the date of such Qualified Termination, become Vested LTIP Units and no longer be subject to forfeiture pursuant to Section 3(e); provided that, notwithstanding that no Continuous Service requirement pursuant to Section 3(d) will apply to the Grantee after the effective date of a Qualified Termination after the Valuation Date, the Grantee will not have the right to Transfer (as defined in Section 7) except by reason of the Grantee's death or request conversion of his or her Vested LTIP Units under the Designation until 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.

(d) If the calculations provided in Section 3(c) are triggered by a Change of Control prior to the Valuation Date, the Grantee's Award LTIP Units shall be multiplied by the Partial Service Factor determined as of the date of the Change of Control and the resulting number of LTIP Units shall become Vested LTIP Units immediately and automatically as of the Valuation Date. If a Change of Control occurs on or after the Valuation Date and prior to January 1, 2016, all Earned LTIP Units shall become Vested LTIP Units immediately and automatically upon the occurrence of the Change of Control.

(e) Notwithstanding the foregoing, in the event any payment to be made hereunder after giving effect to this Section 4 is determined to constitute "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 subject to the six-month delay thereunder, any such payments to be made during the six-month period commencing on the

Grantee's "separation from service" (as defined in Section 409A of the Code) shall be delayed until the expiration of such six-month period.

(f) In the event of a termination of the Grantee's employment other than a Qualified Termination or a termination that is related to a Change of Control, all Award LTIP Units and Earned LTIP Units that have not theretofore become Vested LTIP Units 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, in the event the termination of Grantee's employment is due to Grantee's retirement after age 55, the Committee may determine, in its sole discretion, that all or any portion of the Award LTIP Units or the Earned LTIP Units shall become Vested LTIP Units, together with the terms and conditions upon which any such Award LTIP Units or Earned LTIP Units shall become Vested LTIP Units.

5. Payments by Award Recipients. The Grantee shall have no rights with respect to this Agreement (and the Award evidenced hereby) unless he or she shall have accepted this Agreement prior to the close of business on the date described in Section 3(a) by (a) making a contribution to the capital of the Partnership by certified or bank check or other instrument acceptable to the Committee (as defined in the Plan), of $0.25 (the "Per Unit Purchase Price"), multiplied by the number of Award LTIP Units, (b) signing and delivering to the Partnership a copy of this Agreement and (c) unless the Grantee is already a Limited Partner (as defined in the Partnership Agreement), signing, as a Limited Partner, and delivering to the Partnership a counterpart signature page to the Partnership Agreement (attached as Exhibit B). The Per Unit Purchase Price paid by the Grantee shall be deemed a contribution to the capital of the Partnership upon the terms and conditions set forth herein and in the Partnership Agreement. Upon acceptance of this Agreement by the Grantee, the Partnership Agreement shall be amended to reflect the issuance to the Grantee of the LTIP Units so accepted. Thereupon, the Grantee shall have all the rights of a Limited Partner of the Partnership with respect to the number of Award LTIP Units, as set forth in the Designation and the Partnership Agreement, subject, however, to the restrictions and conditions specified herein. Award LTIP Units constitute and shall be treated for all purposes as the property of the Grantee, subject to the terms of this Agreement and the Partnership Agreement. In the event of the forfeiture of the Grantee's Award LTIP Units pursuant to this Agreement, the Partnership will pay the Grantee an amount equal to the number of Award LTIP Units so forfeited multiplied by the lesser of the Per Unit Purchase Price or the fair market value of an Award LTIP Unit on the date of forfeiture as determined by the Committee.

6. Distributions.

(a) The holders of Award LTIP Units, Earned LTIP Units and Vested LTIP Units (until and unless forfeited pursuant to Section 3(e) or Section 4(f)), shall be entitled to receive the distributions to the extent provided for in the Designation and the Partnership Agreement.

(b) All distributions paid with respect to LTIP Units shall be fully vested and non-forfeitable when paid.

7. Restrictions on Transfer.

(a) Except as otherwise permitted by the Committee in its sole discretion, none of the Award LTIP Units, Earned LTIP Units, Vested LTIP Units or Partnership Units into which Vested LTIP Units have been converted shall be sold, assigned, transferred, pledged, hypothecated, given away or in any other manner disposed or encumbered, whether voluntarily or by operation of law (each such action a "Transfer"); provided that Earned LTIP Units and Vested LTIP Units may be Transferred to the Grantee's Family Members (as defined below) by gift, bequest or domestic relations order; and provided further that the transferee agrees in writing with the Company and the Partnership to be bound by all the terms and conditions of this Agreement and that subsequent transfers shall be prohibited except those in accordance with this Section 7. Additionally, all such Transfers must be in compliance with all applicable securities laws (including, without limitation, the Securities Act) and the applicable terms and conditions of the Partnership Agreement. In connection with any such Transfer, the Partnership may require the Grantee to provide an opinion of counsel, satisfactory to the Partnership, that such Transfer is in compliance with all federal and state securities laws (including, without limitation, the Securities Act). Any attempted Transfer not in accordance with the terms and conditions of this Section 7 shall be null and void, and neither the Partnership nor the Company shall reflect on its records any change in record ownership of any Earned LTIP Units or Vested LTIP Units as a result of any such Transfer,

shall otherwise refuse to recognize any such Transfer and shall not in any way give effect to any such Transfer. Except as provided in this Section 7, this Agreement is personal to the Grantee, is non-assignable and is not transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent and distribution.

8. Miscellaneous.

(a) Amendments; Recoupment.

Notwithstanding the foregoing, Grantee acknowledges that The ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act requires that the Company develop and implement a policy to recover from executive officers excess incentive based compensation paid which is based on erroneous data and for which the Company is required to prepare an accounting restatement ("Incentive Clawback"). At such time as the applicable regulations are finalized with respect to the Incentive Clawback, either through rules and regulations adopted by the Securities and Exchange Commission or the listing exchange on which the Common Stock is then listed, Grantee agrees at the Company's request, to promptly execute any amendment or modification to this Agreement to reflect any Incentive Clawback policy applicable to the LTIP Units adopted by the Company or the Committee to comply with such rules and regulations.

The Company will have the right, at its option, as set forth in the Partnership Agreement, to issue shares of Common Stock in exchange for Partnership Units in accordance with the Partnership Agreement, subject to certain limitations set forth in the Partnership Agreement, and such shares of Common Stock, if issued, will be issued under the Plan. The Grantee acknowledges that the Grantee will have no right to approve or disapprove such determination by the Company.

(e) Compliance With Law. The Partnership and the Grantee will make reasonable efforts to comply with all applicable securities laws.
