7.Broker. Tenant represents and warrants that it has not been represented by any broker or agent in connection with the execution of this Amendment except Partners Commercial Realty, L.P. d/b/a NAI Houston.

broker or agent or similar party other than the above-named broker claiming by, through or under Tenant in connection with this Amendment.

8.Time of the Essence. Time is of the essence with respect to Tenant’s execution and delivery to Landlord of this Amendment. If Tenant fails to execute and deliver a signed copy of this Amendment to Landlord by 5:00 p.m. (in the city in which the Premises is located) on November 20, 2015, this Amendment shall be deemed null and void and shall have no force or effect, unless otherwise agreed in writing by Landlord. Landlord’s acceptance, execution and return of this Amendment shall constitute Landlord’s agreement to waive Tenant’s failure to meet such deadline.

9.Miscellaneous. This Amendment shall become effective only upon full execution and delivery of this Amendment by Landlord and Tenant. This Amendment contains the parties’ entire agreement regarding the subject matter covered by this Amendment, and supersedes all prior correspondence, negotiations, and agreements, if any, whether oral or written, between the parties concerning such subject matter. There are no contemporaneous oral agreements, and there are no representations or warranties between the parties not contained in this Amendment. Except as modified by this Amendment, the terms and provisions of the Lease shall remain in full force and effect, and the Lease, as modified by this Amendment, shall be binding upon and shall inure to the benefit of the parties hereto, their successors and permitted assigns.

10.Ratification. Tenant hereby ratifies and confirms its obligations under the Lease and represents and warrants to Landlord that it has no defenses thereto.
