EXHIBIT “B”

TENANT WORK LETTER

This Tenant Work Letter shall set faith the terms and conditions relating to the renovation of the tenant improvements in the Expansion Space. This Tenant Work Letter is essentially organized chronologically and addresses the issues of the renovations of the Expansion Space, in sequence, as such issues will arise.

SECTION 1

LANDLORDS INITIAL CONSTRUCTION IN THE EXPANSION SPACE

Landlord has constructed, at its sole cost and expense, the base, shell and core (i) of the Expansion Space, and (ii) of the floor of the Building on which the Expansion Space is located (collectively, the “Base, Shell and Core”). Tenant has inspected and hereby approves the condition of the Expansion Space and the Base, Shell and Core, and agrees that the Expansion Space and the Base, Shell and Core shall be delivered to Tenant in their current “as-is” condition. The renovations to the improvements in the Expansion Space shall be designed and constructed pursuant to this Tenant Work Letter.

SECTION 2

IMPROVEMENTS

2.1 Improvement Allowance. Tenant shall be entitled to a one-time improvement allowance (the “Improvement Allowance”) in the amount of $11.00 per usable square foot of the Expansion Space for the costs relating to the initial design and construction of Tenant’s improvements which are permanently affixed to the Expansion Space (the “Improvements”). In no event shall Landlord be obligated to make disbursements pursuant to this Tenant Work Letter in a total amount which exceeds the Improvement Allowance and in no event shall Tenant be entitled to any credit for any unused portion of the Improvement Allowance not used by Tenant by December 31, 2002.

2.2 Disbursement of the Improvement Allowance. Except as otherwise set forth in this Tenant Work Letter, the Improvement Allowance shall be disbursed by Landlord (each of which disbursements shall be made pursuant to Landlord’s disbursement process provided below) for costs related to the construction of the Improvements and for the following items and costs (collectively, the “Improvement Allowance Items”): (i) payment of the fees of the “Architect” and the “Engineers,” as those terms are defined in Section 3.1 of this Tenant Work Letter, and payment of the fees incurred by, and the cost of documents and materials supplied by, Landlord and Landlord’s consultants in connection with the preparation and review of the “Construction Drawings,” as that term is defined in Section 3.1 of this Tenant Work Letter; (ii) the cost of permits and construction supervision fees; (iii) the cost of any changes in the Base, Shell and Core required by the Construction Drawings; and (iv) the cost of any changes to the Construction Drawings or Improvements required by applicable building codes (the “Code”). However, in no event shall more than Three and 00/100 Dollars ($3.00) per usable square foot of the Improvement Allowance be used for the items described in (i) and (ii) above; any additional amount incurred as a result of (i) and (ii) above shall be deemed to constitute an Over-Allowance Amount. During the design and construction of the Improvements, Landlord shall make monthly disbursements of the Improvement Allowance for Improvement Allowance Items for the benefit of Tenant and shall authorize the release of monies for the benefit of Tenant as follows.

2.2.1 Monthly Disbursements. On or before the first day of each calendar month during the design and construction of the Improvements (or such other date as Landlord may designate), Tenant shall deliver to Landlord: (i) request(s) for payment of the “Architect,” “Engineer” and/or “Contractor,” as such terms are defined in Sections 3.1 and 4.1 of this Tenant Work Letter, approved by Tenant, in a form to be provided by Landlord, showing (as applicable) the schedule, by trade, of percentage of completion of the Improvements in the Expansion Space, detailing the portion of the work completed and the portion not completed; (ii) invoices from all of “Tenant’s Agents,” as that term is defined in Section 4.2 of this Tenant Work Letter, for services provided, labor rendered and materials delivered to the Expansion Space; (iii) executed

mechanic’s lien releases from all of Tenant’s Agents which shall comply with the appropriate provisions, as reasonably determined by Landlord, of California Civil Code Section 3262(d); and (iv) all other information reasonably requested by Landlord. Tenant’s request for payment shall be deemed Tenant’s acceptance and approval of the work furnished and/or the materials supplied as set forth in Tenant’s payment request. Thereafter, Landlord shall deliver a check to Tenant in payment of the lesser of: (A) the amounts so requested by Tenant, as set forth in this Section 2.2.1, above, less a ten percent (10%) retention (the aggregate amount of such retentions to be known as the “Final Retention”), and (B) the balance of any remaining available portion of the Improvement Allowance (not including the Final Retention), provided that Landlord does not dispute any request for payment based on non-compliance of any work with the “Approved Working Drawings,” as that term is defined in Section 3.4 below, or due to any substandard work, or for any other reason. Landlord’s payment of such amounts shall not be deemed Landlord’s approval or acceptance of the work furnished or materials supplied as set forth in Tenant’s payment request.

2.2.2 Final Retention. Subject to the provisions of this Tenant Work Letter, a check for the Final Retention payable to Tenant shall be delivered by Landlord to Tenant following the completion of construction of the Expansion Space, provided that (i) Tenant delivers to Landlord properly executed mechanics lien releases in compliance with both California Civil Code Section 3262(d)(2) and either Section 3262(d)(3) or Section 3262(d)(4), (ii) Landlord has determined that no substandard work exists which adversely affects the mechanical, electrical, plumbing, heating, ventilating and air conditioning, life-safety or other systems of the Building, the curtain wall of the Building, the structure or exterior appearance of the Building, or any other tenant’s use of such other tenants leased premises in the Building and (iii) Architect delivers to Landlord a certificate, in a form reasonably acceptable to Landlord, certifying that the construction of the Improvements in the Expansion Space has been substantially completed.

2.2.3 Other Terms. Landlord shall only be obligated to make disbursements from the Improvement Allowance to the extent costs are incurred by Tenant for Improvement Allowance Items. All Improvement Allowance Items for which the Improvement Allowance has been made available shall be deemed Landlord’s property.

2.3 Standard Tenant Improvement Package. Landlord has established specifications (the “Specifications”) for the Building-standard components to be used in the construction of the Improvements in the Expansion Space (collectively, the “Standard Improvement Package”), which Specifications are available upon request. The quality of Improvements shall be equal to or of greater quality than the quality of the Specifications, provided that Landlord may, at Landlord’s option, require the Improvements to comply with certain Specifications.

SECTION 3

CONSTRUCTION DRAWINGS

3.1 Selection of Architect/Construction Drawings. Tenant shall retain an architect/space planner reasonably approved by Landlord (the “Architect”) to prepare the “Construction Drawings,” as that term is defined in this Section 3.1. Tenant shall also retain the engineering consultants designated by Landlord (the “Engineers”) to prepare all plans and engineering working drawings relating to the structural, mechanical, electrical, plumbing, HVAC and lifesafety work of the Improvements. Landlord shall ensure that the charges of the Engineers are competitive (although not necessarily the lowest available). The plans and drawings to be prepared by Architect and the Engineers hereunder shall be known collectively as the “Construction Drawings.” All Construction Drawings shall comply with the drawing format and specifications as reasonably determined by Landlord, and shall be subject to Landlord’s reasonable approval. Tenant and Architect shall verify, in the field, the dimensions and conditions as shown on the relevant portions of the base building plans, and Tenant and Architect shall be solely responsible for the same, and Landlord shall have no responsibility in connection therewith. Landlord’s review of the Construction Drawings as set forth in this Section 3, shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same, for quality, design, Code compliance or other like matters. Accordingly, notwithstanding that any Construction Drawings are reviewed by Landlord or its space planner, architect, engineers and consultants, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space planner, architect, engineers,

and consultants, Landlord shall have no liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained in the Construction Drawings.

3.2 Final Space Plan. Tenant and the Architect shall prepare the final space plan for Improvements in the Expansion Space (collectively, the “Final Space Plan”), which Final Space Plan shall include a layout and designation of all offices, rooms and other partitioning, their intended use, and equipment to be contained therein, and shall deliver the Final Space Plan to Landlord for Landlord’s approval, not to be unreasonably withheld. Landlord shall advise Tenant within ten (10) days after Landlord’s receipt of the Final Space Plan if the same is unsatisfactory or incomplete in any respect and Landlord’s failure to give Tenant written notice of any such objection within said ten (10) day period shall be deemed approval by Landlord of the Final Space Plan.

3.3 Final Working Drawings. Architect and the Engineers shall complete the architectural and engineering drawings for the Expansion Space, and the final architectural working drawings in a form which is complete to allow subcontractors to bid on the work and to obtain all applicable permits (collectively, the “Final Working Drawings”) and shall submit the same to Landlord for Landlord’s approval, not to be unreasonably withheld. Landlord shall advise Tenant within ten (10) days after Landlord’s receipt of the Final Working Drawings if the same is unsatisfactory or incomplete in any respect and Landlord’s failure to give Tenant written notice of any such objection within said ten (10) day period shall be deemed approval by Landlord of the Final Working Drawings.

3.4 Permits. The Final Working Drawings shall be approved by Landlord (the “Approved Working Drawings”) prior to the commencement of the construction of the Improvements. Tenant shall cause the Architect to immediately submit the Approved Working Drawings to the appropriate municipal authorities for all applicable building permits necessary to allow “Contractor,” as that term is defined in Section 4.1, below, to commence and fully complete the construction of the Improvements (the “Permits”). No changes, modifications or alterations in the Approved Working Drawings may be made without the prior written consent of Landlord, which consent shall not be unreasonably withheld.

4.2 Tenant’s Agents. All subcontractors, laborers, materialmen, and suppliers used by the Tenant (such subcontractors, laborers, materialmen, and suppliers, and the Contractor to be known collectively as “Tenant’s Agents”) must be approved in writing by Landlord, which approval shall not be unreasonably withheld or delayed. If Landlord does not approve any of the Tenant’s proposed subcontractors, laborers, materialmen or suppliers, the Tenant shall submit other proposed subcontractors, laborers, materialmen or suppliers for Landlord’s written approval. Notwithstanding the foregoing, the Tenant shall be required to utilize subcontractors designated by Landlord for any mechanical, electrical, plumbing, life-safety, sprinkler, structural and air-balancing work. Landlord shall ensure that the charges of designated subcontractors are competitive (although not necessarily the lowest available).

4.3 Construction of Improvements by Contractor. The Tenant shall independently retain, in accordance with Section 4.1 above, Contractor to construct the Improvements in accordance with the Approved Working Drawings.

4.4 Indemnification & Insurance.

which it is responsible shall be free from any defects in workmanship and materials for a period of not less than one (1) year from the date of completion thereof. All such warranties or guarantees as to materials or workmanship of or with respect to the Improvements shall be contained in the contract or subcontract and shall be written such that such guarantees or warranties shall inure to the benefit of both Landlord and Tenant, as their respective interests may appear, and can be directly enforced by either. Tenant covenants to give to Landlord any assignment or other assurances which may be necessary to effect such right of direct enforcement.

4.4.3 Insurance Requirements.
