15.    Assignment, Etc. The following new paragraphs are hereby inserted after Paragraph 33 of the Sublease:

“34.    Transfers. Subtenant shall not, without the prior consent of Sublandlord and Master Landlord, (a) assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, directly or indirectly, this Sublease or any interest hereunder, by operation of law or otherwise, (b) sublet the Subleased Premises or any part thereof, or (c) otherwise to permit the use of the Subleased Premises by any persons other than Subtenant (all of the foregoing are, collectively, “Transfers” and any person to whom a Transfer is made or sought to be made, a “Transferee”), except that Subtenant may, at any time and from time to time, without the consent of Sublandlord, subject to compliance with the Master Lease, and so long as no monetary default or material non-monetary default beyond all applicable notice and cure periods has occurred under the Sublease, assign this Sublease or any interest hereunder to, or sublease the Subleased Premises or any part thereof, or permit the occupancy of the Subleased Premises by (i) any successor entity of Subtenant resulting from a merger or consolidation with Subtenant, (ii) any entity succeeding to all or substantially all of the business and assets of Subtenant, (iii) any entity which, at the effective or commencement date of the Transfer, is an Affiliate of Subtenant, and (iv) any entity which, at the effective or commencement date of such Transfer, is acquiring all or a bona fide portion of the business being conducted at the Subleased Premises by Subtenant or its Affiliates (any such transfer being herein referred to as an “Exempt Transfer”). An “Affiliate” of Subtenant is a person or entity that directly or indirectly through one or more intermediaries controls, is controlled by or is under common control with Subtenant, or an entity in which any person who controls Subtenant has a direct or indirect interest. For purposes of the definition of “Affiliate,” the word “control” shall mean the power, directly or indirectly, by voting rights, contract or otherwise, to direct or cause the direction of the management or policies of an entity. Promptly following any Transfer, Subtenant shall deliver to Sublandlord documentation evidencing that the Transfer is an Exempt Transfer, together with a copy of the assignment, sublease, or occupancy agreement. Sublandlord shall have no right to recapture space or control the amount of sublease rent or set any other conditions to any Transfer permitted under clauses (a) through (c) above. No assignment or sublease shall release Subtenant from any of its obligations under this Sublease. All assignments and subleases shall be, and shall provide expressly by their terms that they are, subordinate to all the terms, covenants and conditions of this Sublease and the Master Lease.

35.    Early Termination Right. If, at any time prior to termination of the Sublease, Hyatt Hotels Corporation intends to cease using the Building for its principal executive offices (the “Cessation”), then Sublandlord shall deliver written notice thereof (the “Cessation Notice”) to Subtenant and Sublandlord shall designate therein the exact date (the “Cessation Date”) of the Cessation. Subtenant, within the six (6) month period following the later to occur of (a) the Cessation Date designated in the Cessation Notice, and (b) the actual date of Cessation, shall have the right to terminate this Sublease (“Termination Option”) by delivering written notice thereof (“Termination Notice”) to Sublandlord. The Termination Notice shall designate the termination effective date, which in no event shall be earlier than nine (9) months following the date of the Termination Notice. If Subtenant exercises the Termination Option, (i) Subtenant, no later than the thirtieth (30^th) day prior to the termination effective date, shall deliver to Sublandlord a termination fee in an amount equal to the product of six (6) and the monthly Net Rent and Additional Rent payable by Subtenant (without giving effect to any abatement or reduction) for the month preceding the date of delivery of such payment, and (ii) Subtenant shall surrender the Subleased Premises on the termination effective date in the condition required by and in accordance with the terms of Article 13 of the Master Lease. Subtenant shall, after delivery of the Termination Notice, comply with the terms of the Sublease until the date of termination as if no such notice had been given. The Termination Option is conditioned upon no monetary or material non-monetary default beyond all applicable notice and cure periods existing on the date of the Termination Notice or on the termination effective date of this Sublease. If Subtenant provides the Termination Notice and fulfills the conditions described above (subject to the following sentence), this Sublease shall terminate on the termination effective date. If Subtenant fails to fulfill any of the conditions described above, Subtenant’s right under this Paragraph 35 shall be terminated. Notwithstanding any termination of this Sublease pursuant to this Paragraph 35, Subtenant shall continue to be liable to Sublandlord for all rent accruing under the Sublease prior to the termination effective date, the cure of any violations or defaults under this Sublease occurring prior to the date of termination, any indemnities under this Sublease, any provisions of this Sublease which expressly survive any termination of this Sublease, any holdover rent payable as a result of failing to vacate the Subleased Premises on or prior to the termination effective date, and any damages suffered by Landlord as a result of failing to vacate the Subleased Premises on or prior to such termination effective date. Sublandlord shall have all rights and remedies under this Sublease and at law or in equity with respect to the liabilities described in the preceding sentence. The right of Subtenant under this Paragraph 35 terminates if Subtenant assigns the Sublease, except pursuant to an Exempt Transfer(s).

36.    Elevator; Staircase. Subtenant shall provide reasonable non-exclusive access to Sublandlord and its agents and invitees to the staircase and elevator located in the Subleased Premises in order for such parties to access the 48^th floor of the Building.”

5

16.    Confirmation Agreements. At any time and from time to time upon either Sublandlord’s or Subtenant’s request Sublandlord and Subtenant shall execute a Confirmation Agreement confirming Subtenant’s Share and any other information reasonably requested by Sublandlord or Subtenant pertinent to this Sublease.

17.    No Offer. Submission of this Fifth Amendment by Sublandlord to Subtenant is not an offer to enter into this Fifth Amendment but rather is a solicitation for such an offer from Subtenant. Sublandlord shall not be bound by this Fifth Amendment until Sublandlord has executed and delivered the same to Subtenant.

18.    Integration of Sublease and Controlling Language. This Fifth Amendment and the Sublease shall be deemed to be, for all purposes, one instrument. In the event of any conflict between the terms and provisions of this Fifth Amendment and the terms and provisions of the Sublease, the terms and provisions of this Fifth Amendment, in all instances, shall control and prevail.

19.    Severability. If any provision of this Fifth Amendment or the application thereof to any person or circumstances is or shall be deemed illegal, invalid or unenforceable, the remaining provisions hereof shall remain in full force and effect and this Fifth Amendment shall be interpreted as if such legal, invalid or unenforceable provision did not exist herein.

20.    Entire Agreement. This Fifth Amendment and the Sublease contain the entire integrated agreement between the parties respecting the subject matter of this Fifth Amendment and the Sublease and supersede all prior and contemporaneous understandings and agreements other than the Sublease between the parties respecting the subject matter of this Fifth Amendment and the Sublease. There are no representations, agreements, arrangements or understandings, oral or in writing, between or among the parties to this Fifth Amendment relating to the subject matter of this Fifth Amendment or the sublease which are not fully expressed in this Fifth Amendment and the Sublease, and no party hereto has relied upon any other representations, agreements, arrangements or understandings. The terms of this Fifth Amendment and the Sublease are intended by the parties as the final expression of their agreement with respect to those terms and may not be contradicted by evidence of any prior agreement or of any contemporaneous agreement. The parties further intend that no extrinsic evidence whatsoever may be introduced in any judicial proceeding involving this Fifth Amendment (and, for avoidance of doubt, the Sublease is not extrinsic for this purpose).

21.    Successors and Assigns. Each provision of the Sublease and this Fifth Amendment shall extend to and shall bind and inure to the benefit of Sublandlord and Subtenant, their respective heirs, legal representatives, and permitted successors and assigns.

22.    Time of the Essence. Time is of the essence of this Fifth Amendment and the Sublease and each provision hereof.

23.    Multiple Counterparts. This Fifth Amendment may be executed in counterparts, all of which, when taken together, shall constitute a fully executed instrument.

24.    Authority. Sublandlord and Subtenant each represent and warrant that it has full authority to execute and deliver this Fifth Amendment.

6

25.    Real Estate Brokers. Each of Sublandlord and Subtenant represent that it has not dealt with any broker, agent or finder in connection with this Fifth Amendment, and that insofar as each party knows, no brokers have participated in the procurement of Subtenant or in the negotiation of this Fifth Amendment or are entitled to any commission in connection therewith. Each of Sublandlord and Subtenant shall indemnify and hold the other harmless from all damages, judgments, liabilities and expenses (including reasonable attorneys’ fees) arising from its breach of the foregoing representation.

26.    Ratification Generally. Except as amended and modified hereby, the Sublease shall be and shall remain unchanged and in full force and effect in accordance with its terms, and, as the Sublease is amended and modified hereby, the sublease is hereby ratified, adopted and confirmed.
