10. Option Term. Tenant’s right to extend the Lease Term, as provided in Section 2.2 of the Original Lease, shall continue in effect and shall apply to the entire Premises (the Current Premises and Second Expansion Premises). All references in such Section 2.2 to the “expiration of the Lease Term” shall be deemed to refer to January 31, 2023.

11. Contingency. Tenant acknowledges that Suites 300 and 380 are currently subject to tenancies of third parties (the “Third Party Tenants”). This Third Amendment is expressly contingent upon Landlord and the Third Party Tenants fully executing agreements terminating such tenancies no later than June 30, 2016 and the Third Party Tenants having vacated the Second Expansion Premises by August 30, 2016 (the “Third Party Tenant Contingency”). Landlord shall provide Tenant’s broker with regular progress updates on the status of the tenancies of the Third party Tenants. Landlord shall provide Tenant written notice when the Third Party Tenant Contingency has been satisfied. In the event Landlord has not satisfied the Third Party Tenant Contingency by August 30, 2016, then Tenant shall have the right to terminate its obligation to lease the Second Expansion Premises by providing written notice of such termination to Landlord before the Third Party Tenant Contingency is satisfied. If Tenant terminates this Third Amendment as provided herein, Landlord shall return to Tenant the first month’s Base Rent paid by Tenant for the Second Expansion Premises and neither party shall have any further obligation to the other pursuant to this Third Amendment.

12. Brokers. Landlord and Tenant hereby warrant to each other that they have had no dealings with any real estate broker or agent in connection with the negotiation of this Third Amendment other than CBRE, Inc., and the Broderick Group (the “Brokers”), and that they know of no other real estate broker or agent who is entitled to a commission in connection with this Third Amendment. Each party agrees to indemnify and defend the other party against and hold the other party harmless from any and all claims, demands, losses, liabilities, lawsuits, judgments, and costs and expenses (including, without limitation, reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of the indemnifying party’s dealings with any real estate broker or agent, other than the Brokers. The terms of this Paragraph 12 shall survive the expiration or earlier termination of the term of the Lease.

13. No Further Modifications. Except as otherwise set forth in this Third Amendment, the terms and conditions of the Lease remain unchanged and in full force and effect.

14. Counterparts. This Third Amendment may be executed in counterparts, each of which shall be deemed an original, and all of which when executed and delivered shall together constitute one and the same instrument.

15. Authority. Each party represents that the person executing this Third Amendment for such party is acting on behalf of such party and is duly authorized to execute this Fourth Amendment for such party.

16. Entire Agreement. This Third Amendment, together with the Lease, constitutes the entire and complete agreement of the parties with respect to the subject matter hereof, and supersedes all prior or contemporaneous agreements, statements, promises, understandings, arrangements, and commitments.

IN WITNESS WHEREOF, the parties hereto have executed this Third Amendment to Lease as of the date first written above.
