SECTION 14.7. WAIVER OF JURY TRIAL/JUDICIAL REFERENCE.

(a) LANDLORD AND TENANT EACH ACKNOWLEDGES THAT IT IS AWARE OF AND HAS HAD THE ADVICE OF COUNSEL OF ITS CHOICE WITH RESPECT TO ITS RIGHTS TO TRIAL BY JURY, AND, TO THE EXTENT ENFORCEABLE UNDER CALIFORNIA LAW, EACH PARTY DOES HEREBY EXPRESSLY AND KNOWINGLY WAIVE AND RELEASE ALL SUCH RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER PARTY HERETO AGAINST THE OTHER (AND/OR AGAINST ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR SUBSIDIARY OR AFFILIATED ENTITIES) ON ANY MATTERS WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, TENANT’S USE OR OCCUPANCY OF THE PREMISES, AND/OR ANY CLAIM OF INJURY OR DAMAGE. FURTHERMORE, THIS WAIVER AND RELEASE OF ALL RIGHTS TO A JURY TRIAL IS DEEMED TO BE INDEPENDENT OF EACH AND EVERY OTHER PROVISION, COVENANT, AND/OR CONDITION SET FORTH IN THIS LEASE.

(b) IN THE EVENT THAT THE JURY WAIVER PROVISIONS OF SECTION 14.7(a) ARE NOT ENFORCEABLE UNDER CALIFORNIA LAW, THEN THE PROVISIONS OF THIS SECTION 14.7(b) SHALL APPLY. IT IS THE DESIRE AND INTENTION OF THE PARTIES TO AGREE UPON A MECHANISM AND PROCEDURE UNDER WHICH CONTROVERSIES AND DISPUTES ARISING OUT OF THIS LEASE OR RELATED TO THE PREMISES WILL BE RESOLVED IN A PROMPT AND EXPEDITIOUS MANNER. ACCORDINGLY, EXCEPT WITH RESPECT TO ACTIONS FOR UNLAWFUL OR FORCIBLE DETAINER OR WITH RESPECT TO THE PREJUDGMENT REMEDY OF ATTACHMENT, ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER PARTY HERETO AGAINST THE OTHER (AND/OR AGAINST ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR SUBSIDIARY OR AFFILIATED ENTITIES) ON ANY MATTERS WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, TENANT’S USE OR OCCUPANCY OF THE PREMISES AND/OR ANY CLAIM OF INJURY OR DAMAGE, SHALL BE HEARD AND RESOLVED BY A REFEREE UNDER THE PROVISIONS OF THE CALIFORNIA CODE OF CIVIL PROCEDURE, SECTIONS 638 – 645.1, INCLUSIVE (AS SAME MAY BE AMENDED, OR ANY SUCCESSOR STATUTE(S) THERETO) (THE “REFEREE SECTIONS”). ANY FEE TO INITIATE THE JUDICIAL REFERENCE PROCEEDINGS SHALL BE PAID BY THE PARTY INITIATING SUCH PROCEDURE; PROVIDED HOWEVER, THAT THE COSTS AND FEES, INCLUDING ANY INITIATION FEE, OF SUCH PROCEEDING SHALL ULTIMATELY BE BORNE IN ACCORDANCE WITH SECTION 14.6 ABOVE. THE VENUE OF THE PROCEEDINGS SHALL BE IN THE COUNTY IN WHICH THE PREMISES ARE LOCATED. WITHIN TEN (10) DAYS OF RECEIPT BY ANY PARTY OF A WRITTEN REQUEST TO RESOLVE ANY DISPUTE OR CONTROVERSY PURSUANT TO THIS SECTION 14.7(b), THE PARTIES SHALL AGREE UPON A SINGLE REFEREE WHO SHALL TRY ALL ISSUES, WHETHER OF FACT OR LAW, AND REPORT A FINDING AND JUDGMENT ON SUCH ISSUES AS REQUIRED BY THE REFEREE SECTIONS. IF THE PARTIES ARE UNABLE TO AGREE UPON A REFEREE WITHIN SUCH TEN (10) DAY PERIOD, THEN ANY PARTY MAY THEREAFTER FILE A LAWSUIT IN THE COUNTY IN WHICH THE PREMISES ARE LOCATED FOR THE PURPOSE OF APPOINTMENT OF A REFEREE UNDER CALIFORNIA CODE OF CIVIL PROCEDURE SECTIONS 638 AND 640, AS SAME MAY BE AMENDED OF ANY SUCCESSOR STATUTE(S) THERETO. IF THE REFEREE IS APPOINTED BY THE COURT, THE REFEREE SHALL BE A NEUTRAL AND IMPARTIAL RETIRED JUDGE WITH SUBSTANTIAL EXPERIENCE IN THE RELEVANT MATTERS TO BE DETERMINED, FROM JAMS/ENDISPUTE, INC., THE AMERICAN ARBITRATION ASSOCIATION OR SIMILAR MEDIATION/ARBITRATION ENTITY. THE PROPOSED REFEREE MAY BE CHALLENGED BY ANY PARTY FOR ANY OF THE GROUNDS LISTED IN SECTION 641 OF THE CALIFORNIA CODE OF CIVIL PROCEDURE, AS SAME MAY BE AMENDED OR ANY SUCCESSOR STATUTE(S) THERETO. THE REFEREE SHALL HAVE THE POWER TO DECIDE ALL ISSUES OF FACT AND LAW AND REPORT HIS OR HER DECISION ON SUCH ISSUES, AND TO ISSUE ALL RECOGNIZED REMEDIES AVAILABLE AT LAW OR IN EQUITY FOR ANY CAUSE OF ACTION THAT IS BEFORE THE REFEREE, INCLUDING AN AWARD OF ATTORNEYS’ FEES AND COSTS IN ACCORDANCE WITH CALIFORNIA LAW. THE REFEREE SHALL NOT, HOWEVER, HAVE THE POWER TO AWARD PUNITIVE DAMAGES, NOR ANY OTHER DAMAGES WHICH ARE NOT PERMITTED BY THE EXPRESS PROVISIONS OF THIS LEASE, AND THE PARTIES HEREBY WAIVE ANY RIGHT TO RECOVER ANY SUCH DAMAGES. THE PARTIES SHALL BE ENTITLED TO CONDUCT ALL DISCOVERY AS PROVIDED IN THE CALIFORNIA CODE OF CIVIL PROCEDURE, AND THE REFEREE SHALL OVERSEE DISCOVERY AND MAY ENFORCE ALL DISCOVERY ORDERS IN THE SAME MANNER AS ANY TRIAL COURT JUDGE, WITH RIGHTS TO REGULATE DISCOVERY AND TO ISSUE AND ENFORCE SUBPOENAS, PROTECTIVE ORDERS AND OTHER LIMITATIONS ON DISCOVERY AVAILABLE UNDER CALIFORNIA LAW. THE REFERENCE PROCEEDING SHALL BE CONDUCTED IN ACCORDANCE WITH CALIFORNIA LAW (INCLUDING THE RULES OF EVIDENCE), AND IN ALL REGARDS, THE REFEREE SHALL FOLLOW CALIFORNIA LAW APPLICABLE AT THE TIME OF THE REFERENCE PROCEEDING. IN ACCORDANCE WITH SECTION 644 OF THE CALIFORNIA CODE OF CIVIL PROCEDURE, THE DECISION OF THE REFEREE UPON THE WHOLE ISSUE MUST STAND AS THE DECISION OF THE COURT, AND UPON THE FILING OF THE STATEMENT OF DECISION WITH THE CLERK OF THE COURT, OR WITH THE JUDGE IF THERE IS NO CLERK, JUDGMENT MAY BE ENTERED THEREON IN THE SAME MANNER AS IF THE ACTION HAD BEEN TRIED BY THE COURT. THE PARTIES SHALL PROMPTLY AND DILIGENTLY COOPERATE WITH ONE ANOTHER AND THE REFEREE, AND SHALL PERFORM SUCH ACTS AS MAY BE NECESSARY TO OBTAIN A PROMPT AND EXPEDITIOUS RESOLUTION OF THE DISPUTE OR CONTROVERSY IN ACCORDANCE WITH THE TERMS OF THIS SECTION 14.7(b). TO THE EXTENT THAT NO PENDING LAWSUIT HAS BEEN FILED TO OBTAIN THE APPOINTMENT OF A REFEREE, ANY PARTY, AFTER THE ISSUANCE OF THE DECISION OF THE REFEREE, MAY APPLY TO THE COURT OF THE COUNTY IN WHICH THE PREMISES ARE LOCATED FOR CONFIRMATION BY THE COURT OF THE DECISION OF THE REFEREE IN THE SAME MANNER AS A PETITION FOR CONFIRMATION OF AN ARBITRATION AWARD PURSUANT TO CODE OF CIVIL PROCEDURE SECTION 1285 ET SEQ. (AS SAME MAY BE AMENDED OR ANY SUCCESSOR STATUTE(S) THERETO).

H. Prorations. The third sentence of Article XVI of the Lease is hereby deleted in its entirety, and substituted therefore shall be the following:

Prior to commencement of the Tenant Improvements, Landlord shall review with Tenant Landlord’s contractor’s budget for the Tenant Improvements. Unless expressly authorized in writing by Landlord, the Completion Cost shall not include (and no portion of the Landlord Contribution shall be paid for) any costs incurred by Tenant, including without limitation, any costs for space planners, managers, advisors or consultants retained by Tenant in connection with the Tenant Improvements. The Tenant Improvements shall be undertaken on the following terms and conditions: (A) the Tenant Improvements shall be Landlord’s “Building Standard” or such other improvements acceptable to Landlord, (B) the Tenant Improvements shall be substantially completed not later than December 31, 2007 to be eligible for funding by the Landlord’s Contribution, (C) Landlord shall construct and/or install the approved Tenant Improvements in the Premises using its own contractor, and (D) Tenant may request that certain aspects of the Tenant Improvements be performed at night or on weekends at Landlord’s contractor’s standard overtime rates.
