The Accounting Firm shall act as an arbitrator and not an expert and the determination of such Accounting Firm shall constitute an arbitral award and shall be conclusive and binding upon the Parent Parties, the Contributors and the Representative upon which a judgment may be rendered by a court having proper jurisdiction thereover. Parent OP and the Representative shall jointly revise the Proposed Closing Date Calculations as appropriate to reflect the resolution of any objections thereto pursuant to this Section 2.3(d)(ii), and, as revised, such Proposed Closing Date Calculations shall be deemed to set forth the final Net Working Capital, Paid Post-Signing Allowances and Commissions, Closing Date Funded Indebtedness, Company Transaction Expenses and Aggregate Consideration Value, in each case, for all purposes hereunder (including, without limitation, the determination of the Actual Adjustment).

20. Entire Agreement; Assignment.

(a) This Amendment, the Contribution Agreement (including Amendment No. 1 and Amendment No. 2 thereto), the Barceloneta Contribution Agreement and the other Transaction Documents contain the entire agreement of the parties hereto respecting the subject matter hereof and supersede all prior agreements among the parties hereto respecting the same. The parties hereto have voluntarily agreed to define their rights, liabilities and obligations respecting the subject matter hereof exclusively in contract pursuant to the express terms and provisions of this Amendment, the Contribution Agreement (including Amendment No. 1 and Amendment No. 2 thereto), the Barceloneta Contribution Agreement and the other Transaction Documents and the parties hereto expressly disclaim that they are owed any duties or are entitled to any remedies not expressly set forth in this Amendment, the Contribution Agreement (including Amendment No. 1 and Amendment No. 2 thereto), the Barceloneta Contribution Agreement or the other Transaction Documents. Furthermore, the parties hereto each hereby acknowledges that this Amendment embodies the justifiable expectations of sophisticated parties derived from arm’s-length negotiations; all parties to this Amendment specifically acknowledge that no party has any special relationship with another party that would justify any expectation beyond that of ordinary parties in an arm’s-length transaction. The sole and exclusive remedies for any breach of the terms and provisions of this Amendment, the Contribution Agreement (including Amendment No. 1 and Amendment No. 2 thereto), the Barceloneta Contribution Agreement or the other Transaction Documents (including any representations and warranties set forth herein, the Contribution Agreement (including Amendment No. 1 and Amendment No. 2 thereto), the Barceloneta Contribution Agreement or the other Transaction Documents, made in connection herewith, the Contribution Agreement (including Amendment No. 1 and Amendment No. 2 thereto), the Barceloneta Contribution Agreement or the other Transaction Documents or as an inducement to enter into this Amendment, the Contribution Agreement (including Amendment No. 1 and Amendment No. 2 thereto), the Barceloneta Contribution Agreement or the other Transaction Documents) or any claim or cause of action otherwise arising out of or related to the Contemplated Transactions shall be those remedies available at law or in equity for breach of contract only (as such contractual remedies have been further limited or excluded pursuant to the express terms of the Contribution Agreement (including Amendment No. 1 and Amendment No. 2 thereto), the Barceloneta Contribution Agreement or the other Transaction Documents); and each party hereto hereby agrees that no party hereto shall have any remedies or cause of action (whether in contract or in tort) for any statements, communications, disclosures, failures to disclose, representations or warranties not set forth in this Amendment, the Contribution Agreement (including Amendment No. 1 and Amendment No. 2 thereto), the Barceloneta Contribution Agreement or the other Transaction Documents. Notwithstanding the foregoing, claims by any Parent Party against any Contributor, to the extent arising from the Fraud of such Contributor, shall not be prohibited by this Section 20.

(b) This Amendment may not be assigned by any party (whether by operation of law or otherwise) without the prior written consent of Parent REIT, Parent OP, the Company and the Representative. Any attempted assignment of this Amendment not in accordance with the terms of this Section 20 shall be void; provided, however, that so long as such assignment would not prevent or materially impair or delay the Closing of the Contemplated Transactions, Parent REIT, Parent OP or Parent Sub may assign this Amendment and any of their rights under this Amendment to one or more Affiliates of Parent REIT, Parent OP or Parent Sub; provided, that any such assignment shall not relieve Parent REIT, Parent OP or Parent Sub of any of their obligations hereunder.

21. Governing Law. This Amendment, and all claims or causes of action (whether in contract or tort) that may be based upon, arise out of or relate to this Amendment, or the negotiation, execution or performance of this Amendment (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Amendment or as an inducement to enter into this Amendment), shall be governed by the internal laws of the State of Delaware as applicable to agreements made and to be performed entirely within the State of Delaware, without regard to conflict of law principles or rules.

22. Fees and Expenses. Except as otherwise expressly set forth in this Amendment, the Contribution Agreement or Annex E thereof, whether or not the Closing is consummated, all fees and expenses incurred in connection with this Amendment, the Contribution Agreement and the Contemplated Transactions, including, without limitation, the fees and disbursements of counsel, financial advisors and accountants, shall be paid by the party incurring such fees or expenses.

23. Construction; Interpretation. The term “this Amendment” means this Amendment together with all schedules, exhibits and annexes hereto, as the same may from time to time be amended, modified, supplemented or restated in accordance with the terms hereof. The headings contained in this Amendment are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Amendment. No party, nor its respective counsel, shall be deemed the drafter of this Amendment for purposes of construing the provisions hereof, and all provisions of this Amendment shall be construed according to their fair meaning and not strictly for or against any party hereto. Unless otherwise indicated to the contrary herein by the context or use thereof: (i) the words, “herein”, “hereto”, “hereof” and words of similar import refer to this Amendment as a whole, including, without limitation, the Schedules, exhibits and annexes, and not to any particular section, subsection, paragraph, subparagraph or clause contained in this Amendment; (ii) masculine gender shall also include the feminine and neutral genders, and vice versa; and (iii) words importing the singular shall also include the plural, and vice versa.

24. Exhibits, Annexes and Schedules. All exhibits, annexes and Schedules, or documents expressly incorporated into this Amendment, are hereby incorporated into this Amendment and are hereby made a part hereof as if set out in full in this Amendment. The specification of any dollar amount in this Amendment or the inclusion of any specific item in any Schedule is not intended to imply that such amounts, or higher or lower amounts or the items so included or other items, are or are not material, and no party shall use the fact of the setting of such amounts or the inclusion of any such item in any dispute or controversy as to whether any obligation, items or matter not described herein or included in a Schedule is or is not material for purposes of this Amendment.

25. Severability. If any term or other provision of this Amendment is invalid, illegal or unenforceable, all other provisions of this Amendment shall remain in full force and effect so long as the economic or legal substance of the Contemplated Transactions (as amended hereby) is not affected in any manner materially adverse to any party.

26. Counterparts. This Amendment may be executed in one or more counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Amendment by facsimile or scanned pages shall be effective as delivery of a manually executed counterpart to this Amendment.

27. Waiver of Jury Trial. Each party hereto hereby waives, to the fullest extent permitted by law, any right to trial by jury of any claim, demand, action, or cause of action (i) arising under this Amendment or (ii) in any way connected with or related or incidental to the dealings of the parties in respect of this Amendment or any of the transactions related hereto, in each case, whether now existing or hereafter arising, and whether in contract, tort, equity, or otherwise. Each party hereto hereby further agrees and consents that any such claim, demand, action, or cause of action shall be decided by court trial without a jury and that the parties hereto may file a copy of this Amendment with any court as written evidence of the consent of the parties hereto to the waiver of their right to trial by jury.

28. Jurisdiction and Venue. Each of the parties hereto (i) submits to the exclusive jurisdiction of any state or federal court sitting in Delaware, in any action or proceeding (whether in contract or tort) arising out of or relating to this Amendment, or the negotiation, execution or performance of this Amendment (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Amendment or as an inducement to enter into this Amendment), (ii) agrees that all such claims in respect of such action or proceeding shall be heard and determined in any such court and (iii) agrees not to bring any such action or proceeding in any other court. Each of the parties hereto waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other parties hereto with respect thereto. Each of the parties hereto agrees that service of summons and complaint or any other process that might be served in any action or proceeding may be made on such party by sending or delivering a copy of the process to the party to be served at the address of the party and in the manner provided for the giving of notices in Section 12.2 of the Contribution Agreement. Nothing in this Section 28, however, shall affect the right of any party hereto to serve legal process in any other manner permitted by Law. Each party hereto agrees that a final, non-appealable judgment in any action or proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by Law.
