With respect to employee welfare and fringe benefits that are provided on a self-insured basis, (i) BX shall, or shall cause one or more members of the Blackstone Group to, fully perform, pay and discharge, under the Blackstone Welfare Plans, all claims of PJT Personnel that are incurred under such plans through the Closing Date and (ii) PJT HoldCo shall, or shall cause one or more members of the PJT Group to, fully perform, pay and discharge, under the PJT Welfare Plans, after the Closing Date, all claims of PJT Personnel that are incurred on or after the Closing Date.

ARTICLE V

EQUITY AND INCENTIVE COMPENSATION AWARDS

Section 5.1 Treatment of Blackstone Equity Awards of PJT Personnel.

(a) Immediately following the Effective Time, except as otherwise agreed in writing between BX and an award holder, fifty percent (50%) of each outstanding unvested Blackstone Equity Award held by PJT Personnel, other than any such unvested Blackstone Equity Award which is scheduled to vest within 180 calendar days following the Effective Time, will be converted and cancelled (each, a “Converted Blackstone Award”) and replaced by a comparable

13

equity award in accordance with this Agreement (a “Replacement Award”). Such Replacement Award will be (ii) an award of PJT RSUs for each Converted Blackstone Award denominated in Blackstone Common Units and (ii) denominated in PJT LP Units for each Converted Blackstone Award denominated in Blackstone Holdings Units. The number of shares of PJT Class A Shares or PJT LP Units, as applicable, subject to each Replacement Award will be equal to a quotient, the numerator of which is equal to the product of (x) the number of Blackstone Common Units or Blackstone Holdings Units, as applicable, subject to the Converted Blackstone Award and (y) the Blackstone VWAP for the twenty (20)-Trading Day period ended on August 14, 2015, and the denominator of which is the PJT Per-Share TEV. The Replacement Award will be subject to identical vesting and settlement terms as those that applied to such Converted Blackstone Award immediately before the Effective Time; provided, that any vesting conditions and settlement based on continued service to Blackstone or its Affiliates will be based on continued service to PJT HoldCo or its Affiliates.

(b) The portion of any Blackstone Equity Award held by PJT Personnel that is not a Converted Blackstone Award will remain a Blackstone Equity Award (the “PJT Personnel Retained Blackstone Equity Award”). Each PJT Personnel Retained Blackstone Equity Award, except as otherwise agreed in writing between BX and an award holder, either (i) will be adjusted to reflect the value of a distribution of PJT Class A Shares or PJT LP Units or (ii) will receive a distribution from BX of PJT Class A Shares or PJT LP Units, in each case, in connection with the transactions contemplated hereby in accordance with the terms of the Blackstone Equity Incentive Plan, as determined by BX.

Section 5.2 True-Up of Replacement Awards. If during every full twenty-Trading Day period within the True-Up Measurement Period, the Replacement Award Post-Separation Value is less than the Converted Blackstone Award Post-Separation Value during the applicable twenty-Trading Day period, then the Replacement Award holder will be credited with an adjustment to such Replacement Award (a “True-Up Adjustment”). The True-Up Adjustment, if applicable, will provide the holder of a Replacement Award with the right to receive equity or a cash payment based on the excess, if any (the “True-Up Value”), of (x) the Converted Blackstone Award Post-Separation Value for the last 20 Trading Days of the True-Up Measurement Period over (y) the value of the Replacement Award Post-Separation Value for the last 20 Trading Days of the True-Up Measurement Period. The True-Up Adjustment will be payable by BX and settled in cash, Blackstone Common Units, or PJT Class A Shares, as determined by BX in its sole discretion as soon as practicable following the True-Up Measurement Period. If the True-Up Adjustment is settled in Blackstone Common Units or PJT Class A Shares, the Replacement Award holder will receive a number of units or shares, as applicable, with a value equal to the True-Up Value using the Blackstone VWAP or PJT VWAP, as applicable, during the last 20 Trading Days of the True-Up Measurement Period. The True-Up Adjustment will be subject to such other terms and conditions as determined by BX in its sole discretion after consultation with PJT HoldCo. For the avoidance of doubt, a holder of a Replacement Award that is forfeited prior to the end of the True-Up Measurement Period will not be entitled to receive a True-Up Adjustment in respect of such Replacement Award.

Section 5.3 Forfeiture of Replacement Awards. On the tenth (10^th) Business Day following the end of the each fiscal quarter, PJT HoldCo or one of its Affiliates will pay to BX or one its Affiliates an amount equal to the product of (x) the number of Replacement Award

14

shares or units forfeited during the preceding fiscal quarter and (y) the twenty (20)-Trading Day PJT VWAP immediately preceding and including the last day of the preceding fiscal quarter (the “Forfeited Replacement Award Reimbursement”). The Forfeited Replacement Award Reimbursement will be paid in cash or in PJT Class A Shares, at the election of PJT HoldCo. For the avoidance of doubt, PJT HoldCo will not reimburse BX for the value of any forfeited True-Up Adjustment or any forfeited Replacement Award which corresponds to a Converted Blackstone Award that was granted with respect to the 2014 calendar year pursuant to the Blackstone Bonus Deferral Plan. PJT Holdco shall promptly notify Blackstone upon the termination of services of any PJT Personnel resulting in a forfeited Replacement Award.

Section 5.4 Change of Control; Separation from Service. For the avoidance of doubt, (i) the Separation shall not constitute a “Change of Control” under the Blackstone Equity Plan or the Blackstone Bonus Deferral Plan (or their respective underlying documents) and (ii) the transfer of employment and services by a holder of Blackstone Equity Awards from BX and its Affiliates to PJT HoldCo and its Affiliates (and the Separation) shall not constitute a “separation of service” (to the extent not otherwise prohibited by applicable law) for purposes of the Blackstone Equity Plan or the Blackstone Bonus Deferral Plan (or their respective underlying award agreements).

Section 5.5 New PJT Equity Plan. No later than the Effective Time, PJT shall adopt a plan that will provide equity-based awards (including, without limitation, the Replacement Awards) to PJT Personnel (the “New PJT Equity Plan”). The New PJT Equity Plan shall be approved by the shareholders of PJT HoldCo prior to the Effective Time.

Section 5.6 Retention Awards. At the Effective Time, BX shall, or shall cause one or more members of the Blackstone Group to, cause PJT HoldCo, in consultation with the Founder, to issue to PJT Personnel retention awards in the form of PJT Class A Shares, PJT LP Units, and cash-based awards (collectively, the “Retention Awards”) on such terms as set forth on Schedule B-1 hereto, with the form of equity and amount of such award for each recipient as specified on Schedule B-2.

Section 5.7 Savings Clause. The Parties hereby acknowledge that the provisions of this ARTICLE V are intended to achieve certain Tax, legal and accounting objectives and, in the event such objectives are not achieved, the Parties agree to negotiate in good faith regarding such other actions that may be necessary or appropriate to achieve such objectives.

Section 5.8 SEC Registration. As soon as practicable following the Effective Time, PJT HoldCo shall prepare and file with the SEC a registration statement on Form S-8 (or another appropriate form) registering under the Securities Act the offering of at least a number of PJT Class A Shares issuable under the New PJT Equity Plan. PJT HoldCo shall keep such registration statement effective (and maintain the current status of the prospectus required thereby) for so long as any PJT Class A Shares issued pursuant to this ARTICLE V remain outstanding.

ARTICLE VI

ADDITIONAL COMPENSATION MATTERS

Section 6.1 Workers’ Compensation Liabilities. Effective as of the Closing Date, PJT HoldCo shall, or shall cause one or more members of the PJT Group to, assume all Liabilities for PJT Personnel related to any and all workers’ compensation claims and coverage, whether arising under any law of any state, territory, or possession of the U.S. or the District of Columbia, and arising after the Closing Date (the “Workers’ Compensation Liabilities”), and PJT HoldCo shall, or shall cause one or more members of the PJT Group to, be fully responsible for the administration of all such claims; provided, however, if the event giving rise to a workers’ compensation claim occurs over a period both preceding and following the Closing Date, the claim shall be jointly covered under the applicable plans of PJT Holdco and BX and equitably apportioned between them in accordance with Applicable Law or the applicable plan documents. If no member of the PJT Group is able to assume any Workers’ Compensation Liabilities or the administration of any related claim because of the operation of applicable state law or for any other reason, BX shall, or shall cause one or more members of the Blackstone Group to, retain such Liabilities and PJT HoldCo shall, or shall cause one or more members of the PJT Group to, reimburse and otherwise fully indemnify BX and all members of the Blackstone Group for all Workers’ Compensation Liabilities, including the costs of administering the plans, programs or arrangements under which any such Liabilities have accrued or otherwise arisen.

Section 6.2 Code Section 409A. Notwithstanding anything in this Agreement to the contrary (including the treatment of supplemental and deferred compensation plans, outstanding long-term incentive awards and annual incentive awards as described herein), the Parties agree to negotiate in good faith regarding the need for any treatment different from that otherwise provided herein to ensure that the treatment of such supplemental or deferred compensation or long-term incentive award, annual incentive award or other compensation does not cause the imposition of a Tax under Section 409A of the Code. In no event, however, will any Party be liable to another in respect of any Taxes imposed under Section 409A of the Code. For the avoidance of doubt, the transfer of employment and services by a holder of Blackstone Equity Awards from BX and its Affiliates to PJT HoldCo and its Affiliates (and the Separation) on or prior to the Effective Date shall not be intended to constitute a “separation of service” for purposes of Section 409A of the Code.

Section 6.3 Certain Payroll and Annual Cash Incentive Matters.

(a) Post-Distribution Payroll for Pre-Distribution Service. Subject to Section 9.15, in the case of each PJT Personnel, the employer of such individual as of immediately before the Closing Date shall be responsible for paying (and the W-2 and other payroll reporting obligations for) the payroll amount due to such individual for the payroll period (or portion thereof) ending on the Closing Date.

16

(b) Annual Cash Incentives. At the Effective Time, except as set forth below with respect to partners and non-U.S. based employees (and subject to BX’s payment obligations to PJT HoldCo as set forth below), PJT HoldCo shall, or shall cause one or more members of the PJT Group to, assume responsibility for making payments to PJT Personnel in respect of their annual incentive arrangements (“Bonus Arrangements”). BX and PJT HoldCo shall satisfy their respective obligations with respect to the Bonus Arrangements as follows:

(i) Bonus Payments to Employees. PJT HoldCo, or one or more members of the PJT Group, shall pay the Bonus Arrangements in respect of 2015 to PJT Personnel who are employees (and not partners) no later than 75 calendar days following the Effective Date (the “PJT NPP Bonus Payment Date”). On the day immediately preceding the PJT NPP Bonus Payment Date, BX shall, or shall cause one or more members of the Blackstone Group to pay PJT HoldCo an amount equal to the cash portion of any Bonus Arrangements accrued to such PJT Personnel as of the Effective Date (the “NPP Accrued Bonuses”); provided, that the foregoing shall not apply with respect to PJT Personnel who are employees (and not partners) located in a jurisdiction other than the United States, and instead, on the PJT NPP Bonus Payment Date, BX shall, or shall cause one or more members of the Blackstone Group to pay such PJT Personnel an amount equal to the cash portion of any Bonus Arrangements accrued to such PJT Personnel as of the Effective Date in satisfaction of BX’s Bonus Arrangement obligations with respect to such individuals.

(ii) Bonus Payments to Partners. (A) PJT HoldCo, or one or more members of the PJT Group, shall pay the Bonus Arrangements in respect of the period in 2015 following the Effective Date to PJT Personnel who are partners (and not employees) no later than such time as Bonus Arrangements are typically paid by the PJT Group to such PJT Personnel in the ordinary course of business (the “PJT Partner Payment Date”); and (B) on the PJT Partner Payment Date, BX shall, or shall cause one or more members of the Blackstone Group to, pay to such PJT Personnel an amount equal to the cash portion of any Bonus Arrangements accrued to such PJT Personnel as of the Effective Date (the “Partner Accrued Bonuses” and together with the NPP Accrued Bonuses, the “Accrued Bonuses”) in satisfaction of BX’s Bonus Arrangement obligations with respect to such individuals.

(iii) Certain Adjustments; Treatment of Non-Cash Bonuses. Subject to BX’s consent (such consent not to be unreasonably withheld), in the event that due to subsequent developments or events occurring following the Effective Time, including, without limitation, an increase in the levels of compensation in the investment banking industry, there is a material increase in bonuses actually paid to such PJT Personnel above the levels anticipated by the Accrued Bonuses, BX shall be obligated to pay to PJT HoldCo its pro rata portion of such incremental increase based on the portion of the calendar year prior to the Effective Time. On the Effective Date, with respect to any portion of the Accrued Bonuses which is deferred compensation or would have been denominated in Blackstone Common Units or Blackstone Holdings Units pursuant to the terms of the Blackstone Bonus Deferral Plan (the “Non-Cash Portion”), BX shall, or shall cause one or more members of the Blackstone Group to, pay to PJT Holdco or such member of the PJT Group as PJT HoldCo designates an amount in cash equal to the Non-Cash Portion of the Accrued Bonuses. Payment of Bonus Arrangements in respect of 2015 shall be made in accordance with the terms set forth on Schedule 8.7.

17

Section 6.4 Tax Benefits. If any member of the PJT Group actually realizes a cash benefit (including a reduction in payments under the Tax Receivable Agreement or a reduction in cash Taxes otherwise payable) as a result of (i) any True-Up Adjustment (including, without limitation, in connection with the receipt, vesting or delivery of any cash, equity or other property as a result of such True-Up Adjustment), (ii) any PJT Personnel Retained Blackstone Equity Award (including, without limitation, in connection with the receipt, vesting or delivery of any cash, equity or other property pursuant to the foregoing) or (iii) the payment (whether by a member of the Blackstone Group or the PJT Group) of any Accrued Bonuses (including, without limitation, in connection with the receipt, vesting or delivery of any cash, equity or other property attributable to the cash or Non-Cash Portion of any Accrued Bonuses), then PJT HoldCo shall pay the net amount of such cash benefit or such reduction in Taxes to BX (or such member of the Blackstone Group as BX designates). Any such payments shall be made on an annual basis within 9 months following the end of the relevant taxable period in which the applicable member of the PJT Group actually realized such cash benefit or such reduction in Taxes and shall be net of the tax costs on income, if any, to any member of the PJT Group resulting from the payments made by BX in connection with any of its foregoing obligations. PJT HoldCo shall cooperate (and shall cause other members of the PJT Group to cooperate) with BX’s reasonable requests in determining the amount of any cash benefit or reduction in Taxes that could give rise to a payment under this Section 6.4.

ARTICLE VII

Section 8.3 Effect on Employment. Without limiting Section 2.3 or Section 2.4, except as expressly provided in this Agreement, the mere occurrence of the Separation shall not cause any employee to be deemed to have incurred a termination of employment which entitles such individual to the commencement of benefits under any of the Blackstone Benefit Arrangements (provided that PJT Personnel may become eligible for a distribution from the Blackstone Savings Plan in accordance with the terms of such plan).

Section 8.4 Consent of Third Parties.

Section 8.5 Access to Employees. On and after the Closing Date, BX and PJT HoldCo shall, and shall cause each of their respective Affiliates to, use their best efforts to make available to each other those of their employees who may reasonably be needed in order to defend or prosecute any legal or administrative Action (other than a legal action between or among any of

19

the Parties) to which any employee, director or Benefit Arrangement of the Blackstone Group or PJT Group is a party and which relates in any way to their respective employment or to their respective Benefit Arrangements prior to the Closing Date.
