AGREEMENT

NOW, THEREFORE, Landlord and Tenant, in consideration of the mutual promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, agree as follows:

1.Definitions. For purposes of this Amendment, capitalized terms shall have the meanings ascribed to them in the Lease unless otherwise defined herein. The Lease, as amended by this Amendment, is referred to herein as the “Amended Lease.”

2.Additions to Premises. Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the following space on the following terms:

2.1. 777-02 Premises. Conditional upon each Vacating Tenant surrendering its currently occupied portions of the 777-02 Premises to Landlord in accordance with such Vacating Tenant’s lease, and subject to Tenant’s termination options set forth in Section 3 hereof, Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the 777-02 Premises as of the date (the “777-02 Premises Commencement Date”) that Landlord tenders possession of the 777-02 Premises to Tenant in compliance with the terms of the Amended Lease and with the 777-02 Landlord Work (as defined in Section 6.1(a) hereof) substantially complete. If possession is delayed solely because of a Tenant Delay (as defined Section 6.6), then the 777-02 Premises Commencement Date shall be the date that the 777-02 Premises Commencement Date would have occurred but for such delay. From and after the 777-02 Premises Commencement Date, the term “Premises” shall include

the 777-02 Premises. The Term with respect to the 777-02 Premises shall expire on the Term Expiration Date for the New Premises, subject to (a) Tenant’s option to extend the Term of the Lease as provided in Article 44 of the Lease and (b) Tenant’s termination option set forth in Section 3 hereof. Tenant shall execute and deliver to Landlord written acknowledgment of the actual 777-02 Premises Commencement Date within ten (10) days after Tenant takes occupancy of the 777-02 Premises, in the form attached as Exhibit G hereto. Failure to execute and deliver such acknowledgment, however, shall not affect the 777-02 Premises Commencement Date or Landlord’s or Tenant’s liability hereunder. Failure by Tenant to obtain validation by any medical review board or other similar governmental licensing of the 777-02 Premises required for the Permitted Use by Tenant shall not serve to extend the 777-02 Premises Commencement Date. In the event any Vacating Tenant has not vacated all or any portion of the 777-02 Premises by June 1, 2013, Tenant may provide written notice to Landlord of its intent to terminate the Amended Lease with respect to all or any portion of the 777-02 Premises (the “777-02 Premises Termination Notice”). Upon Landlord’s receipt of such notice, Landlord shall have thirty (30) days (the “Cure Period”) to remove all Vacating Tenants from the 777-02 Premises. If, prior to expiration of the Cure Period, all Vacating Tenants have vacated the 777-02 Premises, then such termination notice shall be void and of no further force or effect and the Amended Lease with respect to the 777-02 Premises shall continue in full force and effect. If, prior to the expiration of the Cure Period, all Vacating Tenants have not vacated the 777-02 Premises, then the Amended Lease with respect to the portion of the 777-02 Premises identified in the 777-02 Premises Termination Notice shall terminate upon expiration of the Cure Period, except for those provisions that expressly survive the expiration or earlier termination thereof.

2.2. 777 S-Level Corridor Premises.

Tenant shall execute and deliver to Landlord written acknowledgment of the actual 777 S-Level Corridor Premises Commencement Date within ten (10) days after Tenant takes occupancy of the 777 S-Level Corridor Premises, in the form attached as Exhibit G hereto. Failure to execute and deliver such acknowledgment, however, shall not affect the 777 S-Level Corridor Premises Commencement Date or Landlord’s or Tenant’s liability hereunder. Failure by Tenant to obtain validation by any medical review board or other similar governmental licensing of the 777 S-Level Corridor Premises required for the Permitted Use by Tenant shall not serve to extend the 777 S-Level Corridor Premises Commencement Date.

2.3. 765 2^nd Floor Corridor Premises. Subject to Tenant’s termination options set forth in Section 3 hereof, Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the 000 0^xx Xxxxx Xxxxxxxx Premises as of the Execution Date (the “765 2^nd Floor Corridor Premises Commencement Date”).

III Commencement Date or Landlord’s or Tenant’s liability hereunder. Failure by Tenant to obtain validation by any medical review board or other similar governmental licensing of the 765 Expansion Premises III required for the Permitted Use by Tenant shall not serve to extend the 765 Expansion Premises III Commencement Date.
