    1.  General.  

    (a)  Purpose of Work Letter Agreement.  The purpose of this Agreement is to set forth how the Base Building Improvements (as defined in Section 3(b) below) and the Tenant Improvements (as defined in Section 5 below), are to be constructed, who will undertake the construction of the Base Building Improvements and the Tenant Improvements, who will pay for the construction of the Base Building Improvements and the Tenant Improvements, and the time schedule for completion of the construction of the Base Building Improvements and the Tenant Improvements.

    (c)  Incorporation of Lease Terms.  The provisions of the Lease, except where clearly inconsistent or inapplicable to this Agreement, are incorporated into this Agreement.

    (d)  Landlord to Pay for Base Building improvements.  The Base Building Improvements shall be constructed pursuant to this Agreement by Lessor at Lessor's sole cost and expense.

    (e)  Tenant Improvement Allowance.  The Tenant Improvements shall be constructed by Lessor, at Lessee's expense, subject to Lessor's obligations to provide the Tenant Improvement Allowance as described in Section 6 below.

    2.  Lease Commencement Date.  The "Lease Commencement Date" shall be the date which is the earlier of (i) the date Lessor delivers to Lessee written notice stating that the Premises are Substantially Complete (as defined in Section 2(a)(i) below), and (ii) the date Lessor delivers to Lessee written notice stating the date the Premises would have been Substantially Complete were it not for any Lessee Delay (as defined in Section 2(a)(ii) below).

    3.  Construction Schedule and Procedures.  

    (a)  Selection of Designer.  Lessee has selected Don L. Beck Associates, Inc. as its architect and designer ("Designer")who will be familiar with all applicable Laws and Building Requirements (as defined in Section 3(b) below).

    (b)  Base Building Plans.  Lessor has submitted instructions and Building plans and specifications prepared by TSH Architects and described on the attached Schedule 3 ("Base Building Plans") and the improvements detailed therein ("Base Building Improvements") and all rules, regulations, instructions and procedures promulgated by Lessor with respect to tenant design and/or construction in the Building (collectively, "Building Requirements") sufficient to allow Lessee to complete a Space Plan (as defined in Section 3(c) below). To the extent the Base Building Plans are revised to accommodate the requirements of the City of Campbell during the permit approval process, Lessor shall submit such revised plans to Lessee for its approval, which approval shall not be unreasonably withheld.

    (c)  Preparation and Approval of Space Plan.  Lessee shall submit to the Designer all additional information including occupancy requirements for the Premises ("Information") necessary to enable the Designer to prepare a space plan showing all demising walls, corridors, entrances, exits, doors, interior partitions, and the locations of all offices, conference rooms, computer rooms, mini-service kitchens, and the reception area, and other requirements of Lessee ("Space Plan"). Once completed the Space Plan shall be attached hereto as Schedule 1.

    Lessee shall cause the Designer to submit to Lessee and Lessor the Space Plan with sufficient time to ensure that Lessor can complete its review and Lessee and Lessor can finally approve the Space Plan no later than December 17, 1999.

    (d)  Integration of Final Plans and Construction of Tenant Improvements.  Lessee's Designer shall integrate the Space Plan and any working drawings or engineering drawings that may be required in order to construct the Tenant Improvements as shown on the approved Space Plan into the plans, specifications and drawing for the Base Building Improvements, which integrated drawings ("Final Plans") shall be thereafter delivered by Lessee to Lessor with sufficient time to ensure that Lessor and Lessee can finally approve the Final Plans no later than January 16, 2000.

    (e)  Bidding.  As soon as practical following receipt of all necessary permits and approvals, Lessor shall put the Final Plans out to bid to multiple licensed and insured subcontractors. Lessee may submit subcontractors to Lessor for Lessor's review. Lessor, with input from Lessee, shall select which subcontractors will perform the Tenant Improvements.

    (f)  Notice of Substantial Completion.  Lessor shall deliver to Lessee one (1) week's prior written notice stating the date that the Premises are expected to be Substantially Complete, or would be Substantially Complete were it not for any Lessee Delay.

    4.  Change Orders.  In the event that Lessee requests any changes to the Final Plans after such plans have been approved by Lessee and Lessor, Lessor shall not unreasonably withhold its consent to any such changes, and shall grant its consent to such changes within three (3) business days after Lessor's receipt of same, provided the changes do not adversely affect the Building's structure, systems, equipment or appearance. If any changes requested by Lessee and approved by Lessor increase the cost to Lessor of constructing the Tenant Improvements shown on the Final Plans, Lessor shall provide Lessee invoices documenting and evidencing such increased costs, and Lessee shall reimburse Lessor for such increased costs as provided in Section 8. The costs charged by Lessor to Lessee pursuant to this Section shall be an amount equal to the actual costs incurred by Lessor to review the requested changes and to cause the Tenant Improvements, as reflected by revised Final Plans, to be constructed above the costs that Lessor would have had to pay to cause the Tenant Improvements to be constructed if such changes had not been made. Subject to Section 2(a)(ii) above, if such changes delay Lessor's completion of the work shown on the Final Plans, then such delay shall constitute a Lessee Delay.

    5.  Tenant Improvements.  The term "Tenant Improvements"shall mean all improvements shown in the Final Plans other than the Base Building Improvements. Tenant Improvements shall not include any personal property of Lessee.

    6.  Tenant Improvement Allowance Amount.  Landlord will pay on behalf of Tenant an amount equal to Thirty Dollars ($30.00) per rentable square foot of the Premises, for an approximate total of Eight Hundred Forty Thousand Six Hundred Ninety Dollars ($840,690.00) ("Tenant Improvement Allowance") over and above the items included in the Base Building Improvements, as set forth in the Base Building Plans, for the costs of the design and construction of the Tenant Improvements. The Tenant Improvement Allowance shall be used to pay for permitted Tenant Improvements and shall be disbursed by Landlord to the contractor engaged to construct the Tenant Improvements.

    7.  Tenant Improvement Costs.  The Tenant Improvements' Cost ("Tenant Improvement Costs") shall mean and include any and all costs and expenses of construction the Tenant Improvements, including, without limitation, all of the following:

    8.  Excess Tenant Improvement Costs.  Prior to commencing the Tenant Improvements, Lessor shall submit to Lessee a written statement of the actual Tenant Improvement Costs (the "Actual TI Costs") (which shall include the amount of any overtime projected as necessary to Substantially Complete the Tenant Improvements by the Completion Date if the necessity of using such overtime to meet the Scheduled Completion date was made necessary by a Lessee Delay) as then known by Lessor, and such statement shall indicate the amount, if any, by which the Actual TI Costs exceeds the Tenant Improvement Allowance (including the additional allowance amortized as provided for in Section 7 of the Lease) (the "Excess Tenant Improvement Costs"). The term "Excess Tenant Improvement Costs" shall also include the costs related to any and all Change Orders required by Lessee's requesting a change in the Final Plans following Final Approval for which Lessee was notified of the cost and agreed. Lessee agrees, within five (5) business days after submission to it of such statement, to execute and deliver to Lessor, in the form then in use by Lessor or Lessor's contractor, an authorization to proceed with the Tenant Improvements. No Tenant Improvements shall be commenced until Tenant has fully complied with the preceding provisions of this Section 8.

60


    Lessee shall retain from progress payment bills a percentage of ten percent (10%) until after final acceptance of the project by Lessee, which acceptance shall not be unreasonably withheld, conditioned or delayed. Within five (5) days of final acceptance, but in no event later than thirty (30) days after Substantial Completion, all retention funds shall be paid to Lessor at Lessor's place of business.

    9.  Inspection.  After Lessor has completed the construction of the Tenant Improvements (excepting punch list items) and again thirty (30) days after the Premises are Substantially Complete ("Second Time"), in each case following two (2) business days' advance written notice from Lessee to Lessor, Lessor shall cause the Contractor to inspect the Premises with a representative of Lessee and complete a punch list of unfinished items of the Tenant Improvements. Authorized representatives for Lessor and Lessee shall execute said punch list to indicate their approval thereof. The items listed on such punch list shall be completed by the Contractor within thirty (30) days after the approval of such punch list or as soon thereafter as reasonably practicable.

    10.  Clean-Up Expenses.  Upon Substantial Completion of the Tenant Improvements, Lessor shall thoroughly clean the Premises. The costs of the cleaning provided by Lessor pursuant to this Section shall not be included in Operating Expenses for the Building prior to Lessee's occupancy of the Premises.

    IN WITNESS WHEREOF, the parties have entered into this Agreement as of the date first written above.
