Installations (as defined on Exhibit “E-1”, attached hereto) on or before the 1A Expansion Date. The foregoing notwithstanding, Landlord and Tenant acknowledge and agree that Landlord’s completion of Landlord’s Suite 418A

 5. Tenant Estoppel. Tenant hereby (a) acknowledges, to the best of Tenant’s
knowledge, that Landlord is not in default under the Lease as of the date this Amendment is executed by Tenant, and (b) confirms, to the best of Tenant’s knowledge, that, as of the date this Amendment is executed by Tenant, Landlord has no
outstanding obligations with respect to the Tenant Space that would, with the passage of time, the giving of notice, or both, result in Landlord being in default under the Lease. 

6. Commissions. Tenant represents that it has dealt with no broker, agent or other person in connection with this
Amendment, and that no broker, agent or other person brought about this Amendment. Tenant shall indemnify and hold Landlord harmless from and against any and all claims, losses, costs or expenses (including attorneys’ fees and expenses) by any
broker, agent or other person claiming a commission or other form of compensation by virtue of having dealt with Tenant with regard to the transaction contemplated by this Amendment. The provisions of this paragraph shall survive the expiration of
the Term of the Lease or any renewal or extension thereof. 
 7. Confidentiality. Notwithstanding anything to the
contrary contained in the Lease, each party agrees that the terms and provisions of this Amendment are confidential and constitute proprietary information of the parties and shall be governed by Section 17.19 of the Lease as though the terms
hereof were originally part of the Lease. 
 8. Miscellaneous. 

A. In the event that the terms of the Lease conflict or are inconsistent with those of this Amendment, the terms of this Amendment shall
govern. 
 B. The Lease is hereby amended as and where necessary, even though not specifically referred to herein, in order to
give effect to the terms of this Amendment. Except as amended by this Amendment, the terms of the Lease shall remain in full force and effect. 
 C. Submission of this Amendment for examination does not constitute an offer, right of first refusal, reservation of, or option for any premises in the Building. This Amendment shall become effective only
upon execution and delivery by both Landlord and Tenant.

 D. This Amendment may be executed simultaneously in two or more counterparts each of which
shall be deemed an original, but all of which shall constitute one and the same Amendment. Landlord and Tenant agree that the delivery of an executed copy of this Amendment by facsimile or e-mail shall be legal and binding and shall have the same
full force and effect as if an original executed copy of this Amendment had been delivered.
