ANNEX A
LTIP Units

The following are the terms of the LTIP Units:

1.              Designation. The Partnership Interests designated as Class G 2019 LTIP Units and Class H 2019 LTIP Units are hereby established. Each such class of Partnership Interests shall be designated as LTIP Units. LTIP Units are intended to qualify as profits interests in the Partnership. The number of LTIP Units that may be issued shall not be limited.

2.              Vesting .

A.             Vesting Generally. LTIP Units may, in the sole discretion of the General Partner, be issued subject to vesting, forfeiture and additional restrictions on transfer pursuant to the terms of a Vesting Agreement. The terms of any Vesting Agreement may be modified by the General Partner from time to time in its sole discretion, subject to any restrictions on amendment imposed by the relevant Vesting Agreement or by the terms of any Stock Plan pursuant to which the LTIP Units are issued, if applicable. Subject to the terms of any Vesting Agreement, a holder of LTIP Units shall be entitled to transfer his or her LTIP Units to the same extent, and subject to the same restrictions as holders of OP Units are entitled to transfer their OP Units pursuant to Article 13 of the Agreement.

B.             Forfeiture or Transfer of Unvested LTIP Units. Unless otherwise specified in the relevant Vesting Agreement, upon the occurrence of any event specified in a Vesting Agreement as resulting in either the forfeiture of any LTIP Units, or the repurchase by the Partnership or the General Partner of LTIP Units at a specified purchase price, then upon the occurrence of the circumstances resulting in such forfeiture or repurchase by the Partnership or the General Partner, the relevant LTIP Units shall immediately, and without any further action, be treated as cancelled and no longer outstanding for any purpose, or as transferred to the Partnership or General Partner, as applicable. Unless otherwise specified in the Vesting Agreement, no consideration or other payment shall be due with respect to any LTIP Units that have been forfeited, other than any distributions declared with a record date prior to the effective date of the forfeiture. In connection with any forfeiture or repurchase of LTIP Units, the balance of the portion of the Capital Account of the holder that is attributable to all of his or her LTIP Units shall be reduced by the amount, if any, by which it exceeds the target balance contemplated by Section 7.4(i) of the Agreement, calculated with respect to the holder’s remaining LTIP Units, if any.

C.             Legend. The records of the Partnership evidencing any issuance of LTIP Units, including, without limitation, any certificate evidencing an LTIP Unit shall bear an appropriate legend, as determined by the Partnership in its sole discretion, indicating that additional terms, conditions and restrictions on transfer, including without limitation any Vesting Agreement, apply to the LTIP Unit.

3.              Distributions .

A.             LTIP Distribution Amount. Subject to the terms and conditions of any Vesting Agreement and Section 8.5 of the Agreement, commencing from and after the LTIP Unit Distribution Participation Date established for any LTIP Units, such LTIP Units shall be entitled to receive, if, when and as authorized by the General Partner out of funds or other property legally available for the payment of distributions, (i) to the extent of Profits for a taxable period, distributions equal to the Interim Distribution Amount and (ii) regular, special, extraordinary or other distributions (other than distributions representing proceeds of a sale or other disposition of all or substantially all of the assets of the Partnership) which may be made from time to time, in an amount per unit equal to the amount of any such distributions that would have been payable to such holders if the LTIP Units had been OP Units (if specified in the Vesting Agreement or other documentation pursuant to which the LTIP Units are issued). For purposes of clarification, distributions of the Interim Distribution Amount as provided in Section 8.5 of the Agreement shall be made to LTIP Unit holders to allow such holders to receive an amount of distributions (after taking into account distributions made to LTIP Unit holders prior to the LTIP Unit Distribution Participation Date) as if the LTIP Unit Distribution Participation Date had been the date of grant of such LTIP Units, but only to the extent of Profits realized in the taxable period in which the LTIP Unit Distribution Participation Date occurs, or in subsequent taxable periods. LTIP Units shall also be entitled to receive, if, when and as authorized by the General Partner out of funds or other property legally available for the payment of distributions, distributions representing proceeds of a sale or other disposition of all or substantially all of the assets of the Partnership in an amount per unit equal to the amount of any such distributions payable on the OP Units, whether made prior to, on or after the LTIP Unit Distribution Participation Date, provided that the amount of such distributions shall not exceed

Annex A- 1

the positive balances of the Capital Accounts of the holders of such LTIP Units to the extent attributable to the ownership of such LTIP Units. Distributions on the LTIP Units, if authorized, shall be payable on the LTIP Unit Distribution Payment Date and in such manner as may be authorized by the General Partner; provided that the LTIP Unit Distribution Payment Date shall be the same as the corresponding date relating to the corresponding distribution on the OP Units. The record date for determining which holders of LTIP Units are entitled to receive a distribution shall be the Partnership Record Date for that distribution. All distributions paid with respect to LTIP Units prior to the date on which the determination is made with respect to events resulting in the forfeiture of such LTIP Units or the repurchase by the Partnership or the General Partner of such LTIP Units shall be retained by the holder of such LTIP Units and not subject to forfeiture or restitution in the event that Unvested LTIP Units fail to become Vested LTIP Units. Following such date of determination, no further distributions will be paid with respect to Unvested LTIP Units that have been forfeited or are repurchased by the Partnership or the General Partner, other than any distributions declared with a record date prior to the effective date of the forfeiture or repurchase.

B.             LTIP Unit Distribution Participation Date. The LTIP Unit Distribution Participation Date for each LTIP Unit will be with respect to LTIP Units granted pursuant to any Stock Plan, such date as may be specified in the Vesting Agreement or other documentation pursuant to which such LTIP Units are issued, including without limitation, the Class G 2019 LTIP Units Award annexed hereto as Exhibit A and the Class H 2019 LTIP Units Award annexed hereto as Exhibit B.

4.              Allocations .

LTIP Unitholders shall be entitled to certain special allocations of income and gain under Sections 7.4(g) and 7.4 (i) of the Agreement. For purposes of determining allocations of Profits and Losses pursuant to Section 7.1, to the extent that the LTIP Unit Distribution Participation Date with respect to a LTIP Unit has occurred, such LTIP Unit shall be treated as an OP Unit. Until the LTIP Unit Distribution Participation Date for an LTIP Unit has occurred, each LTIP Unit shall be treated as a fraction of one outstanding OP Unit equal to one OP Unit multiplied by the LTIP Unit Initial Regular Sharing Percentage or the LTIP Unit Initial Special Sharing Percentage with respect to such LTIP Unit, as applicable. The General Partner is authorized in its discretion to adjust the allocations made under this Section 4 of this Annex A after the LTIP Unit Distribution Participation Date, so that the ratio of (i) the total amount of Profits or Losses allocated with respect to each LTIP Unit in the taxable year in which that LTIP Unit’s LTIP Unit Distribution Participation Date falls (excluding special allocations under Sections 7.4(g) and 7.4(i) of the Agreement), to (ii) the total amount distributed to that LTIP Unit with respect to such period (excluding distributions of the Interim Distribution Amount pursuant to Section 8.5 of the Agreement), is more nearly equal to the ratio of (i) the Profits and Losses allocated with respect to the General Partner’s OP Units in such taxable year to (ii) the amounts distributed to the General Partner with respect to such OP Units and such taxable year.

5.              Adjustments .

The Partnership shall maintain at all times a one-to-one correspondence between LTIP Units and OP Units for conversion, distribution and other purposes, including without limitation complying with the following procedures; provided, however, that the foregoing is not intended to alter the LTIP Unit Capital Account Limitation (as defined in Section 7.B of this Annex A), the special allocations pursuant to Sections 7.4(g), 7.4(h) and 7.4(i) of the Agreement, differences between distributions (other than distributions representing proceeds of a sale or other disposition of all or substantially all of the assets of the Partnership) to be made with respect to the LTIP Units and OP Units prior to the LTIP Unit Distribution Participation Date for such LTIP Units, differences between distributions (other than distributions representing proceeds of a sale or other disposition of all or substantially all of the assets of the Partnership) to be made with respect to the LTIP Units and OP Units pursuant to Section 14.2 of the Agreement or Section 3 of this Eighth Amendment to the Agreement in the event that the Capital Accounts attributable to the LTIP Units are less than those attributable to the OP Units due to insufficient special allocations pursuant to Section 7.4(i) of the Agreement or related provisions. If an LTIP Unit Adjustment Event occurs, then the General Partner shall make a corresponding adjustment to the LTIP Units to maintain such one-for-one correspondence between OP Units and LTIP Units. For the avoidance of doubt, the following shall not be LTIP Unit Adjustment Events: (x) the issuance of Partnership Interests in a financing, reorganization, acquisition or other similar business transaction, (y) the issuance of Partnership Interests pursuant to any employee benefit or compensation plan or distribution reinvestment plan, or (z) the issuance of any Partnership Interests to the General Partner in respect of a Capital Contribution to the Partnership of proceeds from the sale of securities by the General Partner. If the Partnership takes an action affecting the OP Units other than actions specifically described above as LTIP Unit Adjustment Events and in the opinion of the General Partner such action would require an adjustment to the

Annex A- 2

LTIP Units to maintain the one-to-one correspondence described above, the General Partner shall make such adjustment to the LTIP Units, to the extent permitted by law and by the terms of any plan pursuant to which the LTIP Units have been issued, in such manner and at such time as the General Partner, in its sole discretion, may determine to be appropriate under the circumstances. If an adjustment is made to the LTIP Units as herein provided, the Partnership shall promptly file in the books and records of the Partnership an officer’s certificate setting forth such adjustment and a brief statement of the facts requiring such adjustment, which certificate shall be conclusive evidence of the correctness of such adjustment absent manifest error. Promptly after filing of such certificate, the Partnership shall mail a notice to each holder of LTIP Units setting forth the adjustment to his or her LTIP Units and the effective date of such adjustment.

6.              Ranking .

The LTIP Units shall rank on parity with the OP Units in all respects and junior to all Preferred Units, with respect to distribution rights and rights upon voluntary or involuntary liquidation, winding up or dissolution of the Partnership, subject to the proviso in the first sentence of Section 5 of this Annex A.

7.              Right to Convert LTIP Units into OP Units .

A.            Conversion Right. A holder of LTIP Units shall have an LTIP Unit Conversion Right, at his or her option, at any time to convert all or a portion of his or her Vested LTIP Units into OP Units. Holders of LTIP Units shall not have the right to convert Unvested LTIP Units into OP Units until they become Vested LTIP Units; provided, however, that when a holder of LTIP Units is notified of the expected occurrence of an event that will cause his or her Unvested LTIP Units to become Vested LTIP Units, such Person may deliver to the Partnership an LTIP Unit Conversion Notice (as hereinafter defined) conditioned upon and effective as of the time of vesting, and such LTIP Unit Conversion Notice, unless subsequently revoked by the holder of the LTIP Units, shall be accepted by the Partnership subject to such condition. The General Partner shall have the right at any time to cause a conversion of Vested LTIP Units into OP Units. In all cases, the conversion of any LTIP Units into OP Units shall be subject to the conditions and procedures set forth in this Section 7 of this Annex A.

B.             Number of Units Convertible. A holder of Vested LTIP Units may convert such Vested LTIP Units into an equal number of fully paid and non-assessable OP Units, giving effect to all adjustments (if any) made pursuant to Section 5 of this Annex A. Notwithstanding the foregoing, in no event may a holder of Vested LTIP Units convert a number of Vested LTIP Units that exceeds the LTIP Unit Capital Account Limitation.

C.             Notice. In order to exercise his or her Conversion Right, a holder of LTIP Units shall deliver a LTIP Unit Conversion Notice to the Partnership in the form attached as Annex B to the Eighth Amendment not less than ten (10) nor more than sixty (60) days prior to the LTIP Unit Conversion Date specified in such LTIP Unit Conversion Notice. Each holder of LTIP Units covenants and agrees with the Partnership that all Vested LTIP Units to be converted pursuant to this Section 7 of this Annex A shall be free and clear of all liens. Notwithstanding anything herein to the contrary (but subject to Section 10.3 of the Agreement), a holder of LTIP Units may deliver a notice pursuant to Section 10.3 of the Agreement relating to those OP Units that will be issued to such holder upon conversion of such LTIP Units into OP Units in advance of the LTIP Unit Conversion Date; provided, however, that redemption of such OP Units by the Partnership shall in no event take place until the LTIP Unit Conversion Date. For clarity, it is noted that the objective of this paragraph is to put a holder of LTIP Units in a position where, if he or she so wishes, the OP Units into which his or her Vested LTIP Units will be converted can be redeemed by the Partnership simultaneously with such conversion, with the further consequence that, if in accordance with Section 10.3 of the Agreement the General Partner delivers to such holder Common Stock (rather than cash), then such holder can have such Common Stock issued to him or her simultaneously with the conversion of his or her Vested LTIP Units into OP Units. The General Partner shall reasonably cooperate with a holder of LTIP Units to coordinate the timing of the different events described in the foregoing sentence.

D.             Forced Conversion. The Partnership, at any time at the election of the General Partner, may cause any number of Vested LTIP Units held by a holder of LTIP Units to be converted in a LTIP Unit Forced Conversion into an equal number of OP Units, giving effect to all adjustments (if any) made pursuant to Section 5 of this Annex A; provided, however, that the Partnership may not cause an LTIP Unit Forced Conversion of any LTIP Units that would not at the time be eligible for conversion at the option of the holder of such LTIP Units pursuant to Section 7.B. of this Annex A (including taking into account the LTIP Unit Capital Account Limitation). In order to exercise its right to cause an LTIP Unit Forced Conversion, the Partnership shall deliver a LTIP Unit Forced Conversion Notice to the holder of Vested LTIP Units in the

Annex A- 3

form attached as Annex C to the Eighth Amendment to the applicable holder not less than ten (10) nor more than sixty (60) days prior to the LTIP Unit Conversion Date specified in such LTIP Unit Forced Conversion Notice. A Forced LTIP Unit Conversion Notice shall be provided in the manner provided in Section 18.1 of the Agreement.

E.             Conversion Procedures. Subject to any redemption of OP Units to be received upon the conversion of Vested LTIP Units, a conversion of Vested LTIP Units for which the holder thereof has given an LTIP Unit Conversion Notice or the Partnership has given a Forced LTIP Unit Conversion Notice shall occur automatically after the close of business on the applicable LTIP Unit Conversion Date without any action on the part of such holder of LTIP Units, as of which time such holder of LTIP Units shall be credited on the books and records of the Partnership with the issuance as of the opening of business on the next day of the number of OP Units issuable upon such conversion. After the conversion of LTIP Units as aforesaid, the Partnership shall deliver to such holder of LTIP Units, upon his or her written request, a certificate of the General Partner certifying the number of OP Units and remaining LTIP Units, if any, held by such Person immediately after such conversion.

F.              Treatment of Capital Account. For purposes of making future allocations under Section 7.4(i) of the Agreement and applying the LTIP Unit Capital Account Limitation, the portion of the Economic Capital Account Balance of the applicable holder of LTIP Units that is treated as attributable to his or her LTIP Units shall be reduced, as of the date of conversion, by the product of the number of LTIP Units converted and the OP Unit Economic Balance.

G.             Mandatory Conversion in Connection with a Transaction. If the Partnership or the General Partner shall be a party to any Transaction, then the General Partner shall, immediately prior to the Transaction, exercise its right to cause a LTIP Unit Forced Conversion with respect to the maximum number of LTIP Units then eligible for conversion, taking into account any allocations that occur in connection with the Transaction or that would occur in connection with the Transaction if the assets of the Partnership were sold at the Transaction price or, if applicable, at a value determined by the General Partner in good faith using the value attributed to the Partnership Interests in the context of the Transaction (in which case the LTIP Unit Conversion Date shall be the effective date of the Transaction and the conversion shall occur immediately prior to the effectiveness of the Transaction).

In anticipation of such LTIP Unit Forced Conversion and the consummation of the Transaction, the Partnership shall use commercially reasonable efforts to cause each holder of LTIP Units to be afforded the right to receive in connection with such Transaction in consideration for the OP Units into which his or her LTIP Units will be converted the same kind and amount of cash, securities and other property (or any combination thereof) receivable upon the consummation of such Transaction by a holder of the same number of OP Units, assuming such holder of OP Units is not a Constituent Person, or an Affiliate of a Constituent Person. In the event that holders of OP Units have the opportunity to elect the form or type of consideration to be received upon consummation of the Transaction, prior to such Transaction the General Partner shall give prompt written notice to each holder of LTIP Units of such election, and shall use commercially reasonable efforts to afford such holders the right to elect, by written notice delivered to the General Partner, the form or type of consideration to be received upon conversion of each LTIP Unit held by such holder into OP Units in connection with such Transaction. If a holder of LTIP Units fails to make such an election, such holder (and any of its transferees) shall receive upon conversion of each LTIP Unit held by him or her (or by any of his or her transferees) the same kind and amount of consideration that a holder of a OP Unit would receive if such holder of OP Units failed to make such an election.

Subject to the rights of the Partnership and the General Partner under any Vesting Agreement and the terms of any Stock Plan under which LTIP Units are issued, the Partnership shall use commercially reasonable efforts to cause the terms of any Transaction to be consistent with the provisions of this Section 7 of this Annex A and to enter into an agreement with the successor or purchasing entity, as the case may be, for the benefit of any holders of LTIP Units whose LTIP Units will not be converted into OP Units in connection with the Transaction that will (i) contain provisions enabling the holders of LTIP Units that remain outstanding after such Transaction to convert their LTIP Units into securities as comparable as reasonably possible under the circumstances to the OP Units and (ii) preserve as far as reasonably possible under the circumstances the distribution, special allocation, conversion, and other rights set forth in the Agreement for the benefit of the holders of LTIP Units.

Annex A- 4

8.              Redemption at the Option of the Partnership .

LTIP Units will not be redeemable at the option of the Partnership; provided, however, that the foregoing shall not prohibit the Partnership from (i) repurchasing LTIP Units from the holder thereof if and to the extent such holder agrees to sell such LTIP Units or (ii) from exercising its LTIP Unit Forced Conversion right.

9.              Voting Rights .

Holders of Vested LTIP Units shall have the right to vote on all matters submitted to a vote of the holders of OP Units; holders of LTIP Units and OP Units shall vote together as a single class, together with any other class or series of Partnership Interests upon which like voting rights have been conferred. In any matter in which the LTIP Units are entitled to vote, including an action by written consent, each LTIP Unit shall be entitled to vote a Percentage Interest equal on a per unit basis to the Percentage Interest represented by each OP Unit.

(a)           Subject to Section 4(c)  and Section 5 , with respect to fifty percent (50%) of the LTIP Units (the “ Absolute Component LTIP Units ”), vesting shall occur as follows:

(c)                                   Notwithstanding that any of the Award LTIP Units may have vested based on performance as provided in Section 4(a)  or Section 4(b) , subject to Section 5 , the Award LTIP Units shall only become vested 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 5 , as applicable:

(a)                                  If the Grantee is a party to a Service Agreement, whether entered into prior or subsequent to the date of this Agreement, and ceases to be an employee of the Company or any of its Affiliates, the provisions of Sections 5(b)  through 5(f)  shall govern the treatment of the Grantee’s Award LTIP Units exclusively, unless the Service Agreement contains, or is amended to contain, provisions that expressly refer to this Section 5(a)  and provides that those provisions of the Service Agreement shall instead govern the treatment of the Grantee’s Award LTIP Units. The foregoing sentence will be deemed an amendment to any applicable Service Agreement to the extent required to apply its terms consistently with this Section 5 , such that, by way of illustration, any provisions of the Service Agreement with respect to accelerated vesting or payout or the lapse of forfeiture restrictions relating to the Grantee’s incentive or other compensation awards in the event of certain types of terminations of the Grantee’s service relationship with the Company (such as, for example, termination at the end of the term, termination without Cause by the Company and/or its Affiliates or termination for Good Reason by the Grantee) shall not be interpreted as requiring vesting to occur with respect to this Award other than as specifically provided in this Section 5 . In the event

Exhibit A- 7

an entity ceases to be a Subsidiary or Affiliate of the Company, such action shall be deemed to be a termination of employment of all employees of that entity for purposes of this Agreement, 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 remaining unvested Award LTIP Units that have not previously been forfeited, effective immediately prior to such event. If a Change of Control occurs, Section 5(f)  shall govern the treatment of the Grantee’s Award LTIP Units exclusively notwithstanding the provisions of Sections 3.3(c), 4.7 and 5.7 of the 2013 Plan.

(b)                                  In the event of termination of the Grantee’s Continuous Service by (A) the Company without Cause, or (B) the Grantee for Good Reason, (C) the Grantee without Good Reason after the expiration of the term of Grantee’s then effective Service Agreement, or (D) by reason of death, Disability or Retirement (each a “Qualified Termination”), prior to the Initial Valuation Date, the Grantee will not forfeit the Award LTIP Units upon such termination, but the following provisions of this Section 5(b) shall modify the determination and vesting of the Absolute Component LTIP Units and Relative Component LTIP Units for the Grantee:

(i)                                      (A) if the date of such Qualified Termination occurs prior to the expiration date of the term of Grantee’s then effective Service Agreement, the calculations provided in Section 4(a)  and Section 4(b)  shall be performed as of the Initial Valuation Date as if the Qualified Termination had not occurred, and (B) if the date of such Qualified Termination occurs after the expiration date of the term of Grantee’s then effective Service Agreement, the calculations provided in Section 4(a)  and Section 4(b)  shall be performed as of the date of such Qualified Termination;

(ii)                                   the number of Absolute Component LTIP Units and Relative Component LTIP Units that would otherwise vest pursuant to Section 4(a)  and Section 4(b)  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 vested LTIP Units for all purposes under this Agreement; provided, however, that if the Qualified Termination is as a result of the Grantee’s Retirement, the Partial Service Factor shall be equal to one (1);

(iii)                                the number of Grantee’s vested Absolute Component LTIP Units and Relative Component LTIP Units as adjusted pursuant to Section 5(b)(ii)  shall no longer be subject to forfeiture pursuant to Section 4(c) ; provided that, notwithstanding that no Continuous Service requirement pursuant to Section4(c)  will apply to the Grantee after the effective date of a Qualified Termination, the Grantee will not have the right to Transfer (as defined in Section 8 ) his Award LTIP Units or request redemption of his Award Common Units under the Partnership Agreement until such dates as of which his Absolute Component LTIP Units and Relative Component LTIP Units, each as adjusted pursuant to Section 5(b)(ii) , would have become vested pursuant to Section 4(c)  absent a Qualified Termination. For the avoidance of doubt, the purpose of this Section 5(b)(iii)  is to prevent a situation where grantees of LTIP Units who have had a Qualified Termination would be able to realize the value of their Award LTIP Units or Award Common Units (through Transfer or redemption) before other grantees of LTIP Units whose Continuous Service continues through the applicable vesting dates set forth in Section 4(c) .

(c)                                   In the event of a Qualified Termination after the Initial Valuation Date, all unvested Award LTIP Units that have not previously been forfeited pursuant to Section 4(d)  shall vest immediately and automatically; provided that, notwithstanding that no Continuous Service requirement pursuant to Section 4(c)  will apply to the Grantee after the effective date of a Qualified Termination, the Grantee and his heirs, assigns or personal representatives will not have the right to Transfer (as defined in Section 8 ) his Award LTIP Units or request redemption of his Award Common Units under the Partnership Agreement until such dates as of which his Absolute Component LTIP Units and Relative Component LTIP Units would have become vested pursuant to Section 4(c)  absent a Qualified Termination. For the avoidance of doubt, the purpose of this Section 5(c)  is to prevent a situation where grantees of LTIP Units who have had a Qualified Termination would be able to realize the value of their Award LTIP Units or Award Common Units

Exhibit A- 8

(through Transfer or redemption) before other grantees of LTIP Units whose Continuous Service continues through the applicable vesting dates set forth in Section 4(c) .

(d)                                  In the event of a termination of the Grantee’s Continuous Service other than a Qualified Termination, all Award LTIP Units except for those that, as of the date at such termination, both (i) have ceased to be subject to forfeiture pursuant to Section 4(a)  and Section 4(b)  and (ii) are vested pursuant to Section 4(c)  shall, without payment of any consideration by the Partnership other than as provided in the last sentence of Section 6 , automatically and without notice terminate, be forfeited and be and become null and void, and neither the Grantee nor any of his successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such Award LTIP Units.

(e)                                   In the event of a Change of Control, the following provisions of this Section 5(e)  shall modify the determination and vesting of the Grantee’s Absolute Component LTIP Units and Relative Component LTIP Units:

(i)                                            If the Change of Control occurs before the Initial Valuation Date, the calculations provided in Section 4(a)  and Section 4(b)  shall be performed as if the Measurement Period ended on the date of the Change of Control.   The number of Absolute Component LTIP Units and Relative Component LTIP Units earned based on such calculation shall continue to be subject to the Continuous Service requirements of Section 4(c) .  If the Change of Control occurs after the Initial Valuation Date, any LTIP Units vested pursuant to Section 4(a)  or Section 4(b)  shall be subject to the continued service requirements of Section 4(c) , subject to Section 5(e)(ii) .

(ii)                                         If (A) during a Change of Control Period the Grantee’s Continuous Service is terminated as a result of a Qualified Termination, or (B) if after a Change of Control the Company or its Successor does not assume, convert, or replace the LTIP Units as calculated in Section 5(e)(i)  with a security with substantially the same rights, privileges, preferences of the LTIP Units, then in each case the LTIP Units described in Section 5(e)(i)  shall immediately vest.

(iii)                                      Notwithstanding the foregoing, if the accelerated vesting of the Award LTIP Units as a result of the Change of Control, when combined with any other amount payable to Grantee by reason of the Change of Control, would constitute an “excess parachute payment” within the meaning of Section 280G of the Code, but for the application of this sentence, then the number of Award LTIP Units that vest by reason of this Section 5(e)  shall be reduced to the minimum extent necessary, after taking into account any similar reductions required to other amounts payable to Grantee by reason of the Change of Control, so that no amount payable to Grantee constitutes an excess parachute payment; provided, however, that the foregoing reduction shall be made only if and to the extent that such reduction would result in an increase in the aggregate payments and benefits to be received by the Grantee by reason of the Change of Control, determined on an after-tax basis (taking into account the excise tax imposed pursuant to Section 4999 of the Code, or any successor provision thereto, any tax imposed by any comparable provision of state law, and any applicable federal, state and local income taxes).

(f)                                    Notwithstanding the foregoing, the vesting of any Award LTIP Units pursuant to this Section 5 that would not otherwise have been vested at the time of the Grantee’s termination shall be conditioned upon the Grantee (i) executing, and not revoking or breaching during the applicable holding period set forth under Section 5(b)(iii)  or Section 5(c)  , a non-disparagement agreement and release of, and covenant not to sue with respect to, any claims against the Company and parties related to the Company in the form required by the Committee, and (ii) complying with any restrictive covenants, including any restrictions on engaging in competitive activities, soliciting service providers or clients, or utilizing confidential information, contained in the Grantee’s Service Agreement.  If the Grantee is required to execute a release of claims pursuant to his Service Agreement as a condition to the receipt of severance benefits, such release shall satisfy the requirement of this Section 5(f) .

6.             Payments by Award Recipients . The Grantee shall have no rights with respect to this Agreement (and the Award evidenced hereby) unless he shall have accepted this Agreement prior to the close of business on the tenth Trading Day

Exhibit A- 9

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 and the admission of the Grantee as a Limited Partner of the Partnership. Thereupon, the Grantee shall have all the rights of a Limited Partner of the Partnership with respect to the number of LTIP Units specified on Schedule A hereto, as set forth in 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.

(ii)                       the LTIP Unit Initial Special Sharing Percentage (as defined in the Partnership Agreement) ( i.e. 0%) of special distributions and other distributions made other than in the ordinary course.

For the avoidance of doubt, after the earlier to occur of the Initial Valuation Date, Award LTIP Units, both vested and (until and unless forfeited pursuant to Section 4 or Section 5 ) unvested, shall be entitled to receive the same distributions payable with respect to Common Units if the payment date for such distributions is after such Initial Valuation Date, even though the record date for such distributions is before the Initial Valuation Date.

(c)                                   All distributions paid with respect to Award LTIP Units, both before and after the Initial Valuation Date, shall be fully vested and non-forfeitable when paid, whether or not the underlying LTIP Units have been become vested pursuant to this Agreement.

Award LTIP Units, when issued, shall constitute and be treated as the property of the Grantee, subject to the terms of this Agreement and the Partnership Agreement. Award LTIP Units will be subject to vesting as provided in  Section 4 and  Section 5 . In connection with this issuance and each subsequent issuance of Award LTIP Units, if any, the Grantee shall make the capital contribution described in Section 6 and shall execute and deliver to the Company and the Partnership such documents, comparable to the documents executed and delivered in connection with this Agreement, as the Company and/or the Partnership reasonably request at any time (including in the future) in order to comply with all applicable legal requirements, including, without limitation, federal and state securities laws.

4.             Vesting of Award LTIP Units . The LTIP Units are subject to time-based vesting over a period of three years, subject to the Grantee’s Continuous Service, as follows:

(a)                                  Subject to Section 5 , 100% of the LTIP Units shall vest on the three year anniversary of the Effective Date (March 22, 2022).

(b)                                  Any Award LTIP Units that do not become vested pursuant to Section 4 or Section 5 shall, without payment of any consideration by the Partnership other than as provided in the last sentence of Section 5 , automatically and without notice or further action by the Company or its Affiliates be forfeited and be and become null and void, and neither the Grantee nor any of his successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such unvested Award LTIP Units.

(c)                                   To the extent that Schedule A  provides for amounts or schedules of vesting that conflict with the provisions of  Section 4 and Section 5 , the provisions of  Schedule A  will be controlling and determinative.

5.             Termination of Grantee’s Service Relationship; Death and Disability; Change of Control .

(a)                                  If the Grantee is a party to a Service Agreement, whether entered into prior or subsequent to the date of this Agreement, and ceases to be an employee of the Company or any of its Affiliates, the provisions of Sections 5(b)  through 5(d)  shall govern the treatment of the Grantee’s Award LTIP Units exclusively, unless the Service Agreement contains, or is amended to contain, provisions that expressly refer to this

Exhibit B- 4

Section 5(a)  and provides that those provisions of the Service Agreement shall instead govern the treatment of the Grantee’s Award LTIP Units. The foregoing sentence will be deemed an amendment to any applicable Service Agreement to the extent required to apply its terms consistently with this Section 5 , such that, by way of illustration, any provisions of the Service Agreement with respect to accelerated vesting or payout or the lapse of forfeiture restrictions relating to the Grantee’s incentive or other compensation awards in the event of certain types of terminations of the Grantee’s service relationship with the Company (such as, for example, termination at the end of the term, termination without Cause by the Company and/or its Affiliates, or termination for Good Reason by the Grantee) shall not be interpreted as requiring vesting to occur with respect to this Award other than as specifically provided in this Section 5 . In the event an entity ceases to be a Subsidiary or Affiliate of the Company, such action shall be deemed to be a termination of employment of all employees of that entity for purposes of this Agreement, 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 remaining unvested Award LTIP Units that have not previously been forfeited, effective immediately prior to such event. If a Change of Control occurs, Section 5(c)  shall govern the treatment of the Grantee’s Award LTIP Units exclusively notwithstanding the provisions of Sections 3.3(c), 4.7 and 5.7 of the 2013 Plan.

(b)                                  (i)                                      In the event of a termination of the Grantee’s Continuous Service as a result of (A) death, (B) Disability, or (C) Retirement all unvested Award LTIP Units shall immediately vest in full as of the date of such termination.

(ii)                                   In the event of termination of the Grantee’s Continuous Service during the term of Grantee’s Service Agreement, or at any time if Grantee is not subject to a Service Agreement, in each case not during a Change of Control Period by (A) the Company without Cause, or (B) the Grantee for Good Reason (each a “ Qualified Termination ”), in either case prior to the Final Vesting Date, unvested Award LTIP Units shall vest on a pro rata basis based on the product of the total number of Award LTIP Units multiplied by the Partial Service Factor.

(iii)                                In the event of a termination of the Grantee’s Continuous Service during a Change of Control Period by (A) the Company without Cause, or (B) the Grantee for Good Reason, all unvested Award LTIP Units shall immediately vest in full as of the date of such termination.

(iv)                               If the Grantee is subject to a Service Agreement, in the event of a termination of the Grantee’s Continuous Service after the term of Grantee’s Service Agreement but not during a Change of Control Period for any reason other than by the Company for Cause, all unvested Award LTIP Units shall immediately vest in full as of the date of such termination.

(v)                                  Notwithstanding the acceleration of vesting of Award LTIP Units that may occur pursuant to this Section 5(b) , the Grantee will not have the right to Transfer (as defined in Section 8 ) his Award LTIP Units or request redemption of his Award Common Units under the Partnership Agreement until such dates as of which such Award LTIP Units would have become vested pursuant to Section 4 absent Grantee’s death, Disability, Retirement or Qualified Termination, as applicable. For the avoidance of doubt, the purpose of this Section 5(b)(v)  is to prevent a situation where grantees of LTIP Units who have been terminated due to death, Disability, Retirement or a Qualified Termination would be able to realize the value of their Award LTIP Units or Award Common Units (through Transfer or redemption) before other grantees of LTIP Units whose Continuous Service continues through the applicable vesting dates set forth in Section 4(a) .

(c)                                   In the event of a termination of the Grantee’s Continuous Service other than a Qualified Termination or a termination due to death, Disability, Retirement, by the Company without Cause after the expiration of the term of Grantee’s Service Agreement, by the Grantee for any reason after the expiration of the term of Grantee’s Service Agreement, or, during a Change of Control Period, by the Company without Cause or by Grantee for Good Reason, all Award LTIP Units except for those that, as of the date at such termination, have vested pursuant to Section 4 , without payment of any consideration by the Partnership other than as provided in the last sentence of Section 6 , automatically and without notice terminate, be forfeited and be and become null and void, and neither the Grantee nor any of his successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such Award LTIP Units.

Exhibit B- 5

Notwithstanding the foregoing, if the accelerated vesting of the Award LTIP Units as a result of a termination without Cause or for Good Reason during a Change of Control Period, when combined with any other amount payable to Grantee by reason of the Change of Control, would constitute an “excess parachute payment” within the meaning of Section 280G of the Code, but for the application of this sentence, then the number of Award LTIP Units that vest by reason of this Section 5(c) shall be reduced to the minimum extent necessary, after taking into account any similar reductions required to other amounts payable to Grantee by reason of the Change of Control, so that no amount payable to Grantee constitutes an excess parachute payment; provided, however, that the foregoing reduction shall be made only if and to the extent that such reduction would result in an increase in the aggregate payments and benefits to be received by the Grantee by reason of the Change of Control, determined on an after-tax basis (taking into account the excise tax imposed pursuant to Section 4999 of the Code, or any successor provision thereto, any tax imposed by any comparable provision of state law, and any applicable federal, state and local income taxes). Any Award LTIP Units that do not vest by reason of the foregoing sentence shall be forfeited.

(d)                                  Notwithstanding the foregoing, the vesting of any Award LTIP Units pursuant to Section 5(b)  that would not otherwise have been vested at the time of the Grantee’s termination shall be conditioned upon the Grantee (i) executing, and not revoking or breaching during the holding period set forth under Section 5(b)(v) , a non-disparagement agreement and release of, and covenant not to sue with respect to, any claims against the Company and parties related to the Company in the form required by the Committee, and (ii) complying with any restrictive covenants, including any restrictions on engaging in competitive activities, soliciting service providers or clients, or utilizing confidential information, contained in the Grantee’s Service Agreement.  If the Grantee is required to execute a release of claims pursuant to his Service Agreement as a condition to the receipt of severance benefits, such release shall satisfy the requirement of this Section 5(d) .

6.             Payments by Award Recipients . The Grantee shall have no rights with respect to this Agreement (and the Award evidenced hereby) unless he shall have accepted this Agreement prior to the close of business on the tenth Trading Date following the Effective Date by (a) making a contribution to the capital of the Partnership by certified or bank check or other instrument acceptable to the Committee or the Board, of $0.01 (the “ Per Unit Purchase Price ”), multiplied by the number of LTIP Units to be issued to the Grantee as part of this Award, (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 hereto as Exhibit A ). 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 and the admission of the Grantee as a Limited Partner of the Partnership. Thereupon, the Grantee shall have all the rights of a Limited Partner of the Partnership with respect to the number of LTIP Units specified on Schedule A hereto, as set forth in 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 Per Unit Purchase Price multiplied by the number of Award LTIP Units so forfeited.

7.             Distributions .

(a)                                  The holder of the Award LTIP Units shall be entitled to receive distributions with respect to such Award LTIP Units to the extent provided for in the Partnership Agreement, as modified hereby.

(b)                                  The Class H 2019 LTIP Unit Distribution Participation Date (as defined in the Partnership Agreement) for the Award LTIP Units shall be the Final Vesting Date; provided that prior to such date Award LTIP Units shall be entitled to a percentage of distributions to holders of Common Units under the Partnership Agreement equal to the following:

(i)                          the LTIP Unit Initial Regular Sharing Percentage (as defined in the Partnership Agreement) ( i.e. 10%) of regular periodic distributions; and

(ii)                       the LTIP Unit Initial Special Sharing Percentage (as defined in the Partnership Agreement) ( i.e. 0%) of special distributions and other distributions made other than in the ordinary course.

Exhibit B- 6

For the avoidance of doubt, after the Final Vesting Date, Award LTIP Units shall be entitled to receive the same distributions payable with respect to Common Units if the payment date for such distributions is after the Final Vesting Date, even though the record date for such distributions is before the Final Vesting Date.

(c)                                   All distributions paid with respect to Award LTIP Units, both before and after the Final Vesting Date, shall be fully vested and non-forfeitable when paid, whether or not the underlying LTIP Units have become vested pursuant to this Agreement.

8.             Restrictions on Transfer .    Except as otherwise permitted by the Committee or the Board in its sole discretion, none of the Award LTIP Units granted hereunder nor any of the Common Units of the Partnership into which such Award LTIP Units may be converted (the “ Award Common Units ”) shall be sold, assigned, transferred, pledged, hypothecated or otherwise disposed of or encumbered (whether voluntarily or involuntarily or by judgment, levy, attachment, garnishment or other legal or equitable proceeding) (each such action a “ Transfer ”), or redeemed in accordance with the Partnership Agreement (a) prior to vesting (or, in the case of LTIP Units that vest as a result of a Qualified Termination pursuant to Section 5, prior to the date they would otherwise have vested), (b) for a period of two (2) years beginning on the Effective Date other than in connection with a Change of Control, and (c) unless such Transfer is in compliance with all applicable securities laws (including, without limitation, the Securities Act of 1933, as amended (the “ Securities Act ”)), and such Transfer is in accordance with the applicable terms and conditions of the Partnership Agreement;  provided  that, upon the approval of, and subject to the terms and conditions specified by, the Committee or the Board, unvested Award LTIP Units that have been held for a period of at least two (2) years may be Transferred to (i) the spouse, children or grandchildren of the Grantee (“ Immediate Family Members ”), (ii) a trust or trusts for the exclusive benefit of the Grantee and such Immediate Family Members, (iii) a partnership in which the Grantee and such Immediate Family Members are the only partners, or (iv) one or more entities in which the Grantee has a 10% or greater equity interest, provided 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 of unvested Award LTIP Units shall be prohibited except those in accordance with this  Section 8 . In connection with any Transfer of Award LTIP Units, 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 of Award LTIP Units not in accordance with the terms and conditions of this  Section 8  shall be null and void, and the Partnership shall not reflect on its records any change in record ownership of any 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 of any LTIP Units. 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. Similar adjustments may be made in the event of any such transaction or event involving the capital structure of the Partnership.

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 Award Common 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 Stock Plan.
