B.    Tenant desires to construct a parking structure at the Project as more

NOW, THEREFORE, in consideration of the foregoing Recitals, which are
incorporated herein by this reference, the mutual promises and conditions
contained herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Landlord and Tenant hereby agree
as follows:
1.
Construction of P2 Phase 1 Parking Structure. Tenant shall construct, which
construction is being performed at Tenant’s election and for Tenant’s benefit,
the P2 Phase 1 Parking Structure, at Tenant’s sole cost and expense, pursuant to
the terms of the P2 Phase 1 Parking Structure Work Letter attached to this
Fourth Amendment as Exhibit A. Tenant shall complete the P2 Phase 1 Parking
Structure in a good and workman like manner and in compliance with all Legal
Requirements. Tenant shall use commercially reasonable efforts to cause the P2
Phase 1 Parking Structure Improvements and the Visitor’s Center Tenant
Improvements to be Substantially Completed (all as defined in the P2 Phase 1
Parking Structure Work Letter) by the date set forth in the Schedule attached to
the P2 Phase 1 Parking Structure Work Letter for the Substantial Completion of
the P2 Phase 1 Parking Structure Improvements and the Visitor’s Center Tenant

and the Visitor’s Center Tenant Improvements on or before the date that is 180
days after the date set forth in the Schedule attached to the P2 Phase 1 Parking
Structure Work Letter for the Substantial Completion of the P2 Phase 1 Parking

date may be extended by Force Majeure delays) shall constitute a Default by
Tenant under the Lease.

The P2 Phase 1 Parking Structure shall be constructed in the location within the
Project identified on the site plan attached to this Fourth Amendment as Exhibit
B.
2.
P2 Phase 1 Parking Structure Costs. Tenant shall be responsible for all Parking
Structure Costs (as defined in the P2 Phase 1 Parking Structure Work Letter)
incurred, whether incurred by Landlord or Tenant, in connection with the P2
Phase 1 Parking Structure, including, without limitation, costs incurred in
connection with the design, permitting and construction of the P2 Phase 1
Parking Structure (and including, without limitation, the cost of the Visitor’s
Center Tenant Improvements).

3.
No Removal or Restoration. Notwithstanding anything to the contrary contained in
the Lease, Tenant shall have no obligation or right to remove the P2 Phase 1
Parking Structure, including, without limitation, the Visitor’s Center Tenant
Improvements, security equipment serving the P2 Phase 1 Parking Structure, or
site work at the Project associated with the construction of the P2 Phase 1
Parking Structure, and Tenant shall be required, at Tenant’s sole cost and
expense, to maintain the P2 Phase 1 Parking Structure (including, without
limitation, the Visitor’s Center Tenant Improvements and the security equipment
serving the P2 Phase 1 Parking Structure) at all times in good condition and
repair during the Term.

4.
Parking. Commencing on the Substantial Completion of the P2 Phase 1 Parking
Structure Improvements and the Visitor’s Center Tenant Improvements, the second
paragraph of Section 10 of the Lease is hereby deleted and replaced with the
following:

“Notwithstanding anything to the contrary contained herein, in no event shall
Tenant have the right to use more parking spaces at the Project than the maximum
number of parking spaces permitted by applicable Legal Requirements.
Notwithstanding anything to the contrary contained in this Lease, Tenant may
only elect to exercise any of its Extension Rights under Section 40 with respect
to less than all of the Buildings, if, as of the commencement date of the
applicable Extension Term, (i) there are 4 parking spaces per 1,000 rentable
square feet available for each Building with respect to which Tenant does not
extend the Term of the Lease and those parking spaces are in reasonably close
proximity to the applicable Building, and (ii) there are 4 parking spaces per
1,000 rentable square feet available for each Building with respect to which
Tenant has elected to extend the Term of the Lease. Tenant agrees to indemnify,
defend, save and hold Landlord harmless from and against any and all Claims
(including, without limitation, from any Governmental Authority) at any time(s)
(including, without limitation, during the construction of any Building(s)
and/or Parking Structure(s), including Building 6 and the P2 Phase 1 Parking
Structure) in connection with there not being sufficient parking spaces at the
Project as may be required by applicable Legal Requirements.”
5.
Operating Expenses. For the avoidance of any doubt, Tenant shall continue to be
required to pay all Operating Expenses with respect to the Project, including
any and all Operating Expenses relating the to P2 Phase 1 Parking Structure.

6.
Signage. Subject to Tenant obtaining all applicable governmental approvals,
Tenant may install, at Tenant’s sole cost and expense, signage bearing Tenant’s
name and logo on the P2 Phase 1 Parking Structure (the “P2 Phase 1 Signage”). So
long as Tenant is the sole tenant of the Project, Tenant shall continue to have
the right to have the P2 Phase 1 Signage on the P2 Phase 1 Parking Structure.
Tenant acknowledges and agrees that the P2 Phase 1 Signage, including, without
limitation, the size, color and location, shall be subject to Landlord’s signage
program at the Project and all applicable Legal Requirements, and shall
otherwise be reasonably acceptable to Landlord. Tenant shall be responsible, at
Tenant’s sole cost and expense, for the maintenance of the P2 Phase 1 Signage,
for the removal of the P2 Phase 1 Signage upon the earlier of (i) the date that
Tenant is no longer the sole tenant of the Project, or (ii) at the expiration or
earlier termination of the Term of the Lease, and for the repair of all damage
(excluding discoloration of the façade of the P2 Phase 1 Parking Structure)
resulting from such removal.

7.
Project Development Costs. Tenant acknowledges that Landlord previously entered
into an agreement with DGA pursuant to which DGA provided services, for the
benefit of Tenant, in connection with the master planning and entitlements for
the Project (the “DGA Contract”). Tenant approved the DGA Contract and
acknowledges and agrees that there are outstanding costs and fees due under the
DGA Contract in the amount of $58,570.00 (the “Outstanding DGA Costs”). Tenant
shall reimburse Landlord for the full amount of the Outstanding DGA Costs on or
before the date that is 10 days after the mutual execution and delivery of this
Fourth Amendment by the parties.

Notwithstanding anything to the contrary contained herein, immediately following
the date of this Fourth Amendment, the DGA Contract shall terminate, Landlord
shall have no further obligations under the DGA Contract, and Tenant shall enter
into a direct contract with DGA for the remaining master planning and
entitlements for the Project (the “Replacement DGA Contract”). Landlord and
Tenant anticipate that the costs and fees payable under the Replacement DGA
Contract and to other vendors, the City of San Diego and other third parties in
connection with the master planning and entitlements for the Project will be
approximately $562,500.00 (which amount has been approved by Tenant) and Tenant
shall be responsible for all such costs. Tenant acknowledges that there is no
guaranty that the costs and expenses incurred in connection with the master
planning and entitlements for the Project will not exceed such amount, and
Tenant shall be responsible for all additional costs and expenses incurred under
the Replacement DGA Contract and all additional costs and expenses reasonably
approved in advance by Tenant and incurred in connection with the master
planning and entitlements for the Project payable to other vendors, the City of
San Diego and other third parties. Notwithstanding that Tenant will directly
enter the Replacement DGA Contract with DGA and that Tenant will be responsible
for all of the Outstanding DGA Costs and all other costs and fees incurred in
connection with the master planning and entitlements for the Project pursuant to
this Section 7, Tenant shall have no right or authority to make any decisions
regarding the master planning or entitlements for the Project. Tenant
acknowledges and agrees that Landlord shall make all decisions regarding the
master planning and entitlements for the Project, subject to Tenant’s approval
which shall not be unreasonably withheld, conditioned or delayed, and Landlord
shall have sole signature authority with respect to all such master planning and
entitlements. Neither Landlord nor Tenant shall have any liability to the other
if Landlord is not successful in obtaining the desired entitlements for the
Project. Landlord shall be named as a third party beneficiary of the Replacement
DGA Contract and of any warranties made by DGA under the Replacement DGA
Contract. Tenant shall be responsible for paying DGA directly for all costs and
fees incurred under the Replacement DGA Contract. Landlord shall have no
obligation to bear any portion of the costs and fees incurred under the
Replacement DGA Contract or any other costs and fees incurred in connection with
the master planning and entitlements for the Project.
8.
Brokers. Landlord and Tenant each represents and warrants that it has not dealt
with any broker, agent or other person (collectively, “Broker”) in connection
with the transaction reflected in this Fourth Amendment and that no Broker
brought about this transaction, other than Cushman & Wakefield. Landlord and
Tenant each hereby agrees to indemnify and hold the other harmless from and
against any claims by any Broker claiming a commission or other form of
compensation by virtue of having dealt with Tenant or Landlord, as applicable,
with regard to this leasing transaction. Tenant shall be responsible for all
commissions, if any, due to Cushman & Wakefield arising out of the execution of
this Fourth Amendment.

9.
Disclosure. For purposes of Section 1938 of the California Civil Code, as of the
date of this Amendment, Tenant acknowledges having been advised by Landlord that
the Project has not been inspected by a certified access specialist.

10.
OFAC. Landlord and Tenant are currently (a) in compliance with and shall at all
times during the Term of the Lease remain in compliance with the regulations of
the Office of Foreign Assets Control (“OFAC”) of the U.S. Department of Treasury
and any statute, executive order, or regulation relating thereto (collectively,
the “OFAC Rules”), (b) not listed on, and shall not during the term of the Lease
be listed on, the Specially Designated Nationals and Blocked Persons List,
Foreign Sanctions Evaders List or the Sectoral Sanctions Identifications List,
which are all maintained by OFAC and/or on any other similar list maintained by
OFAC or other governmental authority pursuant to any authorizing statute,
executive order, or regulation, and (c) not a person or entity with whom a U.S.
person is prohibited from conducting business under the OFAC Rules.

11.
Miscellaneous.

respect to the subject matter hereof and supersedes all prior and
contemporaneous oral and written agreements and discussions. This Fourth

the parties hereto, and their respective successors and assigns.

of which shall be deemed an original, but all of which when taken together shall
constitute one and the same instrument. The signature page of any counterpart
may be detached therefrom without impairing the legal effect of the signature(s)
thereon provided such signature page is attached to any other counterpart
identical thereto except having additional signature pages executed by other

and provisions of the Lease are hereby amended to the extent necessary to give

of the P2 Phase 1 Parking Structure for federal income tax purposes and neither
party shall take an inconsistent position on any income tax return.
