WITNESSETH:

WHEREAS, the Board of Directors of HLT (the “Board”) has determined that it is appropriate, desirable and in the best interests of HLT and its stockholders to separate HLT into three separate, publicly traded companies, one for each of (i) the HLT Retained Business (as defined herein), which shall be owned and conducted, directly or indirectly, by HLT, (ii) the Ownership Business (as defined herein), which shall be owned and conducted, directly or indirectly, by PK (which will elect to be a REIT (as defined herein)), and (iii) the Timeshare Business (as defined herein), which shall be owned and conducted, directly or indirectly, by HGV;

WHEREAS, in order to effect such separation, the Board has determined that it is appropriate, desirable and in the best interests of HLT and its stockholders (i) to enter into a series of transactions after giving effect to which (A) HLT and/or one or more of its Subsidiaries (as defined herein) will, collectively, own all of the HLT Retained Assets (as defined herein) and assume (or retain) all of the HLT Retained Liabilities (as defined herein), (B) PK and/or one or more of its Subsidiaries will, collectively, own all of the Ownership Assets (as defined herein) and assume (or retain) all of the Ownership Liabilities (as defined herein) and (C) HGV and/or one or more of its Subsidiaries will, collectively, own all of the Timeshare Assets (as defined herein) and assume (or retain) all of the Timeshare Liabilities (as defined herein) and (ii) for HLT to distribute to the holders of its common stock, par value $0.01 per share (“HLT Common Stock”), on a pro rata basis (in each case without consideration being paid by such stockholders) (A) all of the outstanding shares of common stock, par value $0.01 per share, of PK (the “PK Common Stock”), and (B) all of the outstanding shares of common stock, par value $0.01 per share, of HGV (the “HGV Common Stock”) (such transactions as they may be amended or modified from time to time, collectively, the “Plan of Reorganization”); and

WHEREAS, it is the intention of the Parties that each of the distributions by HLT of all of the PK Common Stock (the “PK Distribution”) and HGV Common Stock (the “HGV Distribution” and together with the PK Distribution, the “External Distributions”) qualifies as a tax-free distribution within the meaning of Section 355 of the Internal Revenue Code of 1986, as amended (the “Code”).

For purposes of determining whether and to what extent a transaction shall be taken into account for purposes of this definition, any recapitalization or other action resulting in a shift of voting power or any redemption or repurchase of shares of stock shall be treated as an indirect acquisition of shares of stock by the benefitted or non-exchanging stockholders.

For purposes hereof, none of the Spinoff Parties or their respective Subsidiaries shall be considered an “Affiliate” of any of the other Parties or their respective Subsidiaries (determined on the same basis).

For the avoidance of doubt, the sum (immediately before the Reallocation Event) of the Blackstone-HLT Percentage Shift Limit and HLT Percentage Shift Limit, or Blackstone-HGV Percentage Shift Limit and HGV Percentage Shift Limit, as applicable, shall equal the sum (immediately after the Reallocation Event), of the Reallocation Event Reduction plus the Blackstone-HLT Percentage Shift Limit and HLT Percentage Shift Limit, or Blackstone-HGV Percentage Shift Limit and HGV Percentage Shift Limit, as applicable. Notwithstanding anything to the contrary in this Section 4.5, if the Blackstone Representative or the relevant Spinoff Party provides an Unqualified 355(e) Opinion with respect to a purported Reallocation Event to HLT, such purported Reallocation Event shall not constitute a Reallocation Event.

Section 4.6 Cooperation. The Parties shall reasonably cooperate (and, in the case of HLT and HGV, cause the members of the HLT Group and the HGV Group, respectively, to reasonably cooperate) in obtaining any Unqualified Device Opinion or Unqualified 355(e) Opinion (including making reasonable representations required in connection with any such opinion), including by maintaining and making available to each other all records necessary in connection with such opinions and making employees available on a mutually convenient basis to provide additional information or explanation of any material provided hereunder.

Section 4.7 Effect of Rulings and Opinion on Section 355(e) Calculations. For purposes of computing the (a) HLT Applicable Percentage, (b) HGV Applicable Percentage, (c) Blackstone-HLT Applicable Percentage, (d) Blackstone-HGV Applicable Percentage, (e) Blackstone-PK Applicable Percentage or (f) Reallocation Event Reduction, any calculation of the shift of ownership of one or more of the Spinoff Parties under Section 355(e) shall take into account (i) any IRS private letter ruling received by one or more of the Spinoff Parties and/or the Blackstone Entities and (ii) any unqualified “will” opinion of a Qualified Tax Advisor (or, with respect to an opinion delivered by HLT, “should” opinion) addressed to HLT and in form and substance reasonably satisfactory to HLT, without substantive qualifications, in each case addressing the manner in which the calculation of such shift is performed.

Section 5.8 No Circumvention. The Parties agree not to directly or indirectly take any actions, act in concert with any Person who takes an action, or cause or allow any Subsidiary of such Party to take any actions (including the failure to take a reasonable action) such that the resulting effect is to materially undermine the effectiveness of any of the provisions of this Agreement, the Distribution Agreement or any Ancillary Agreement.

Section 5.9 Subsidiaries. Each of the Parties shall cause to be performed, and hereby guarantees the performance of, all actions, agreements and obligations set forth herein to be performed by any Subsidiary of such Party or by any entity that becomes a Subsidiary of such Party on and after the Effective Time, to the extent such Subsidiary remains a Subsidiary of the applicable Party.

Section 5.10 Third Party Beneficiaries. This Agreement is solely for the benefit of the Parties and should not be deemed to confer upon third parties any remedy, claim, liability, reimbursement, claim of action or other right in excess of those existing without reference to this Agreement; provided that the Blackstone Holders shall be jointly and severally liable for any losses, costs, expenses, damages, claims and other liabilities (including reasonable attorneys’ fees) incurred by PK or any of its Affiliates arising, directly or indirectly, from or in connection with any breach by any Blackstone Holder of its obligations hereunder.

Section 5.11 Title and Headings. Titles and headings to sections herein are inserted for the convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement.

The Parties agree that the remedies at law for any breach or threatened breach, including monetary damages, may be inadequate compensation for any loss and that the Parties may be irreparably harmed as a result. Accordingly, any defense in any action for specific performance that a remedy at law would be adequate is waived. Any requirements for the securing or posting of any bond with such remedy are waived by the Parties to this Agreement.

Section 5.14 Governing Law. This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware without reference to any choice-of-law or conflicts of law principles that would result in the application of the laws of a different jurisdiction.

Section 5.15 Consent to Jurisdiction. Each of the Parties irrevocably submits to the exclusive jurisdiction of (a) the Court of Chancery of the State of Delaware and any appeals court thereof or (b) if such court does not have subject matter jurisdiction, any other state or federal court located within the County of New Castle in the State of Delaware and any appeals court thereof (the courts referred to in clauses (a) and (b), the “Delaware Courts”), for the purposes of any suit, action, or other proceeding to compel arbitration or for provisional relief in aid of arbitration or to prevent irreparable harm, and to the non-exclusive jurisdiction of the Delaware Courts for the enforcement of any award issued thereunder. Each of the Parties further agrees that service of any process, summons, notice, or document by U.S. registered mail to such Party’s respective address set forth above shall be effective service of process for any action, suit, or proceeding in the Delaware Courts with respect to any matters to which it has submitted to jurisdiction in this Section 5.15. Each of the Parties irrevocably and unconditionally waives any objection to the laying of venue of any action, suit, or proceeding arising out of this Agreement or the transactions contemplated hereby in the Delaware Courts, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

Section 5.16 Waiver of Jury Trial. EACH OF THE PARTIES HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH OF THE PARTIES HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 5.16.

Section 5.17 Force Majeure. No Party (or any Person acting on its behalf) shall have any liability or responsibility for failure to fulfill any obligation (other than a payment obligation) under this Agreement so long as and to the extent to which the fulfillment of such obligation is prevented, frustrated, hindered, or delayed as a consequence of circumstances of Force Majeure (as defined in the Distribution Agreement). A Party claiming the benefit of this provision shall, as soon as reasonably practicable after the occurrence of any such event: (a) notify the other applicable Parties of the nature and extent of any such Force Majeure condition and (b) use due diligence to remove any such causes and resume performance under this Agreement as soon as feasible.

Section 5.19 Changes in Law.

(a) Any reference to a provision of the Code, Treasury Regulations, or a Law of another jurisdiction shall include a reference to any applicable successor provision or Law.

(b) If, due to any change in applicable Law or regulations or their interpretation by any court of Law or other governing body having jurisdiction subsequent to the date hereof, performance of any provision of this Agreement or any transaction contemplated hereby shall become impracticable or impossible, the Parties hereto shall use their commercially reasonable best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such provision.

Section 5.20 Severability. In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby. The Parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions, the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

Section 5.21 No Waiver. No failure to exercise and no delay in exercising, on the part of any Party, any right, remedy, power or privilege hereunder shall operate as a waiver hereof or thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. No waiver shall be effective unless it is in writing and is signed by the Party asserted to have granted such waiver.
