California Civil Code Section 1938. Pursuant to California Civil Code § 1938, Landlord hereby states that the Premises have not undergone inspection by a Certified Access Specialist (CASp) (defined in California Civil Code § 55.52) and provides the following notification to Tenant: "A Certified Access Specialist (CASp) can inspect the subject premises and determine whether the subject premises comply with all of the applicable construction-related accessibility standards under state law. Although state law does not require a CASp inspection of the subject premises, the commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for the CASp inspection, and the cost of making any repairs necessary to correct violations of construction related accessibility standards within the premises." In accordance with the foregoing, Landlord and Tenant agree that if Tenant requests a CASp inspection of the Premises, then Tenant shall pay (i) the fee for such inspection, and (ii) the cost of making any repairs necessary to correct violations of construction-related accessibility standards within the Premises;

Package HVAC Units. In the event Tenant desires to utilize any existing dedicated heating, ventilation and air conditioning units ("Package Units") within any portion of the Premises, or installs, as part of the Tenant Improvement Work or as an Alteration, new Package Units within any portion of the Premises, the plans and specifications for any Package Units shall be subject to Landlord's reasonable approval. If Tenant elects to utilize or install Package Units within the Premises, Tenant shall also install, at Tenant's sole cost and expense, separate meters or at Landlord's option, sub-meters, in order to measure the amount of electricity furnished to such Package Units and Tenant shall be responsible for Landlord's actual cost of supplying electricity to such units as reflected by such meters or sub-meters, which amounts shall be payable on a monthly basis as Additional Rent. Tenant shall be responsible for maintenance and repair of the Package Units pursuant to Section 25.5 of the Original Lease and such units may be subject to removal by Tenant upon the expiration or earlier termination of the Lease pursuant to Section 25.5 of the Original Lease.

Surrender. Except as required under Section 23 of the Original Lease (regarding removal of Lines) and except as required under Section 25.5 of the Original Lease and Section 8 above (regarding Units and Package Units), and except for Tenant's obligation to remove all of Tenant's full floor signage (i.e., any signage in the elevator lobby, hallways, or other areas of any full floor leased by Tenant), upon the expiration or earlier termination of the Lease, as amended hereby, Tenant shall surrender possession of the Premises to Landlord in as good condition and repair as exists as of the date of this Fourth Amendment, except for reasonable wear and tear, casualty, condemnation and repairs that are Landlord's express responsibility hereunder. Notwithstanding the foregoing, (a) in the event any Alterations are installed by Tenant in the Premises after the date of this Fourth Amendment which are not approved by Landlord, Tenant shall remove such non-approved Alterations upon the expiration or earlier termination of the Lease and repair any damage associated with such removal, and (b) in the event Alterations are installed by Tenant in the Premises after the date of this Fourth Amendment (including, without limitation, any Tenant Improvement Work to be installed in the Premises by Tenant in accordance with the Work Letter attached to the Third Amendment as Exhibit A), which are approved by Landlord, Tenant shall not be required to remove such Tenant Improvement Work or Alterations upon the expiration or earlier termination of the Lease. For clarity, nothing contained in this Section 10 shall be construed to limit Tenant's obligation to remove the Lines, Units, Package Units upon the expiration or earlier termination of the Lease.

Capitalized terms used but not defined in this Fourth Amendment shall have the meanings given in the Lease.

Tenant shall indemnify and hold Landlord, its trustees, members, principals, beneficiaries, partners, officers, directors, employees, mortgagee(s) and agents, and the respective principals and members of any such agents harmless from all claims of any brokers, other than Savills Studley, claiming to have represented Tenant in connection with this Fourth Amendment.
