The calculation of this load factor may vary from floor to floor but remains consistent on any given floor.  Landlord shall cause Ostgren Associates (“Landlord’s Architect”) to measure the usable area of the Premises and the Building and to determine the load factor applicable to each floor of the Building, all in accordance with BOMA (ANSI Z65.1-1996) as soon as possible following the execution of this Lease by Landlord and Tenant, but in no event later than January 2, 2006.  Landlord shall promptly provide Tenant with written notice of Landlord’s determination of the Rentable Area of the Premises and the Building and the load factor applicable to each floor of the Building, together with the calculations on which such determinations were based (the “Rentable Area Calculation Notice”).  During the sixty (60) day period commencing on Tenant’s receipt of the Rentable Area Calculation Notice (the “Review Period”), Tenant shall have the right, at Tenant’s sole cost, to cause MacCracken Architect or another architect engaged by Tenant and reasonably approved by Landlord to verify Landlord’s determination of the Rentable Area of the premises or the Building and the applicable load factors in accordance with BOMA (ANSI Z65.1-1996).  If the Rentable Area of the Premises or the Building or the load factor applicable to any floor of the Building on which the Premises are located, as determined by Tenant’s architect pursuant to the provisions of this Section 1.18, varies from the Rentable Area of the Premises or the Building or the load factor applicable to any floor of the Building on which the Premises are located as specified in the Rentable Area Calculation Notice by less than five percent (5%) (a “Minor Variation”), then for the purposes of this Lease the Rentable Area of the Premises and the Building and the load factors for such floors shall be as specified in the Rentable Area Calculation Notice; provided, however, Tenant and/or Tenant’s Architect may in such event advise Landlord’s Architect in writing of any error(s) in Landlord’s Architect’s measurements or calculations prior to the expiration of the Review Period, and if Landlord’s Architect in its sole good faith judgment agrees that it has made such error(s), then Landlord’s Architect will revise its calculations accordingly and the Rentable Area of the Premises or the Building or the load factors for such floors in which the Minor Variation was the result of such error shall be appropriately adjusted by Landlord’s Architect.  If the Rentable Area of the Premises or the Building or the load factor applicable to any floor of the Building on which the Premises are located, as determined by Tenant’s architect pursuant to the provisions of this Section 1.18, varies from the figures specified in the Rentable Area Calculation Notice by five percent (5%) or more, then provided that Tenant provides Landlord with written notice of such variance, together with the calculations on which Tenant’s architect’s determination were based (an “Objection Notice”) by the end of the Review Period, Landlord and Tenant shall each instruct their respective architects to attempt in good faith to resolve the discrepancy in calculations.  If Landlord’s architect and Tenant’s architect do not reach a mutual agreement on the disparate measurements and calculations by the date which is thirty (30) days after the date of the Objection Notice, Landlord shall engage Huntsman Architectural Group (“Huntsman”) to verify the determination of the Rentable Area of the Building and the load factor applicable to each floor of the Building factors in accordance with BOMA (ANSI Z65.1-1996), and shall instruct Huntsman to specify whether the figures specified in the Rentable Area Calculation Notice or the figures specified in the Objection Notice are closest to the figures established by Huntsman, and for the purposes of this Lease the Rentable Area of the Premises and Building and the load factor applicable to each floor of the Building shall be as set forth in the Rentable Area Calculation Notice or the Objection Notice, as specified by Huntsman.  If Huntsman selects the figures in the Rentable Area Calculation Notice, Tenant shall reimburse Landlord for the cost of Huntsman’s services hereunder.  If Tenant does not provide an Objection Notice by the end of the Review Period, then for the purposes of this Lease the Rentable Area of the Premises and the Building and the load factors for such floors shall be as specified in the Rentable Area Calculation Notice. The load factors established pursuant to this Section 1.18 are referred to as the “Approved Load Factors”. Landlord and Tenant acknowledge that if additional common corridors or other common area elements are constructed on any floor of the Building, the load factor for such floor shall be modified. Upon determination of the Rentable Area of the Premises and the Building and the Approved

4

Load Factors, Landlord and Tenant shall execute an amendment to this Lease, which amendment shall (i) state the Rentable Area of the Building, as determined in accordance with this Section 1.18, (ii) state the Rentable Area of the Premises, as determined in accordance with this Section 1.18, using the Approved Load Factors, (iii) state Tenant’s Percentage Share based on the Rentable Area of the Premises and the Rentable Area of the Building, (iv) state the Base Rent payable by Tenant under this Lease and the Improvement Allowance payable by Landlord pursuant to the Work Letter, based on the Rentable Area of the Premises, and (v) state the amount of the Security Deposit calculated in accordance with the Basic Lease Information page.  If there is a modification in the size of the Premises pursuant to the provisions of Section 2.2 of this Lease, the provisions of Section 2.2 below shall apply.

1.19        “Security Deposit” shall mean the amount specified on the Basic Lease Information page to be paid by Tenant to Landlord and held and applied pursuant to Section 4.6.

1.20        “Tenant Improvements” shall mean the improvements to the Premises installed or to be installed for Tenant pursuant to Exhibit B.

1.21        “Tenant’s Broker” shall mean the individual or corporate broker identified on the Basic Lease Information page as the broker for Tenant, if any.

1.22        “Tenant’s Proportionate Share” is specified on the Basic Lease Information page and is based on the percentage which the Rentable Area of the Premises bears to the total Rentable Area of the Building.  If the Rentable Area of the Premises changes as a result of the modification of the Premises in accordance with the provisions of Section 2.2 below, Tenant’s Proportional Share shall be recalculated.

1.23        “Term” shall mean the period commencing with the Commencement Date and ending at 11:59 p.m. on the Expiration Date.

1.24        Other Terms.  Other terms used in this Lease and on the Basic Lease Information page shall have the meanings given to them herein and thereon.

ARTICLE 2.
PREMISES

2.1          Lease.  Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the Premises upon all of the terms, covenants and conditions set forth in this Lease.

2.2          Modification of Premises.  Tenant shall have the right to increase or decrease the size of the Premises described in the Basic Lease Information and shown on the attached Exhibit A, provided the specific configuration of the modified Premises shall be subject to Landlord’s approval, which shall not be unreasonably withheld, and such modification shall be made in accordance with the terms and conditions of this Section 2.2.  If Tenant desires to increase the size of the Second Floor Premises or the Fourth Floor Premises, or to decrease the size of the Second Floor Premises, the Third Floor Premises, or the Fourth Floor Premises, Tenant shall provide Landlord with written notice of such election (the “Premises Modification Notice”) not later than sixty (60) days after the full execution of this Lease by Landlord and Tenant (the “Premises Modification Notice Deadline”), which Premises Modification Notice shall include a depiction of the desired configuration of the modified Premises.  Tenant’s right to modify the Premises is subject to the following terms and conditions: (i) the total Rentable Area of the Premises following such modification shall not be less than 92,000 rentable square feet, (ii) the Second Floor Premises may be increased to include part or all of the area labeled “Initial Expansion Area” on attached Exhibit A (the “Initial Expansion Area”), (iii) the configuration of each increment of the Premises must be permitted by applicable laws regarding exiting, (iv) space included in the Premises on each floor shall be reasonably contiguous, (v) if Tenant leases a portion of the Initial Expansion Area, the balance of the Initial Expansion Area not leased by Tenant, taken together with the balance of the then-unleased space on the floor, shall in Landlord’s reasonable judgment be readily leaseable for general office purposes with legal exiting and access to restrooms and elevators, and (vi) if Tenant surrenders a portion of the Premises on any floor, the space so surrendered, taken together with the balance of the then-unleased space on the floor, shall in Landlord’s reasonable judgment be readily leaseable for general office purposes with legal exiting and access to restrooms and elevators.  Landlord may consider such

5

factors as Landlord reasonably deems relevant in determining whether space is readily leaseable for general office purposes, including, without limitation, whether it is less than 2,000 feet, is of an unusual configuration, or consists entirely of interior space (i.e., without windows).  If Landlord disapproves of Tenant’s proposed configuration of the Premises as depicted in the Premises Modification Notice, Landlord shall provide Tenant with written notice of such disapproval, and Landlord and Tenant shall cooperate in good faith to identify a configuration which is acceptable to both Landlord and Tenant.  Upon Landlord’s approval of Tenant’s desired modification of the Premises, Landlord and Tenant shall execute an amendment to this Lease, which amendment shall (i) modify the description of the Second Floor Premises, Third Floor Premises, or Fourth Floor Premises, as applicable, (ii) confirm the Rentable Area of the Premises as so modified, as reasonably determined by Landlord in accordance with BOMA (ANSI Z65.1-1996), using the Approved Load Factors established pursuant to Section 1.18 above, (iii) confirm Tenant’s Percentage Share based on the modified Rentable Area of the Premises, (iv) replace Exhibit A to this Lease with a substitute exhibit depicting the modified Premises, (v) state the Base Rent payable by Tenant under this Lease and the Improvement Allowance payable by Landlord pursuant to the Work Letter, based on the Rentable Area of the modified Premises, and (vi) confirm the recalculated amount of the Security Deposit pursuant to Section 4.7 below.  If Tenant does not deliver the Premises Modification Notice by the Premises Modification Notice Deadline, Tenant shall have no further rights under this Section 2.2.  If Tenant desires to verify the usable square footage of the modified Premises, Tenant shall cause Tenant’s architect to verify the measurement of the usable square footage of the modified Premises within thirty (30) days after Landlord provides Tenant with Landlord’s calculation thereof.  Landlord and Tenant shall use good faith efforts to resolve any dispute regarding the calculation of the usable square footage of the Premises.

2.3          Acceptance of Premises.  Tenant acknowledges that: (a) it has been advised by Landlord, Landlord’s Broker and Tenant’s Broker, if any, to satisfy itself with respect to the condition of the Premises (including, without limitation, the HVAC, electrical, plumbing and other mechanical installations, security and environmental aspects) and the present and future suitability of the Premises for Tenant’s intended use; (b) Tenant has made such inspection and investigation as it deems necessary with reference to such matters and assumes all responsibility therefor as the same relate to Tenant’s occupancy of the Premises and the term of this Lease; and (c) neither Landlord nor any of Landlord’s agents has made any oral or written representations or warranties with respect to the condition, suitability or fitness of the Premises other than as may be specifically set forth in this Lease.  Tenant accepts the Premises in its AS IS condition, subject to all matters of record and applicable laws, ordinances, rules and regulations, subject to the completion of Landlord’s Work, as described in Exhibit B to this Lease, and subject to completion of the Tenant Improvements described in Exhibit B to this Lease.  Tenant acknowledges that neither Landlord nor Landlord’s Broker nor any of Landlord’s agents has agreed to undertake or pay for any alterations or additions or to perform any maintenance or repair of the Premises except for the routine maintenance and janitorial work specified herein and except as may be expressly set forth in Exhibit B.

2.4          Early Access; Move In Period.  Tenant shall be given access to the Premises for a period of fourteen (14) days (the “Move In Period”) following Substantial Completion of the Tenant Improvements (as such terms are defined in the Work Letter attached as Exhibit B), in order for Tenant and/or Tenant’s contractors or vendors to install furniture, cabling and trade fixtures as Tenant elects in accordance with the terms hereof; provided, however, that Tenant and Tenant’s contractors shall first have provided the certificates of insurance called for under this Lease, including pursuant to Sections 11.1 and 11.2 below. During the period of such early access, (i) Tenant shall be solely responsible for any equipment, fixtures, furniture or material brought into the Premises in connection with such early occupancy, and for any loss or damage thereto from any cause whatsoever, excluding only the gross negligence or deliberate misconduct of Landlord or Landlord’s contractors, and (ii) Tenant shall cooperate with Landlord to facilitate the completion of the Tenant Improvements, provided that Landlord shall ensure that the Premises are substantially free of Landlord’s contractors in order to maximize the benefits to Tenant of the Move In Period.  During the Move In Period Tenant may use the Building’s freight elevator and loading dock on a non-exclusive basis during business hours, free of charge, other than as provided in Rule 5 of the Rules and Regulations attached hereto as Exhibit D, if applicable.  If Tenant desires use of the freight elevator or loading dock during other than during business hours on business days, then Tenant may reserve such use in compliance with the Building’s rules and procedures and shall pay Landlord a reasonable amount for providing any security services in connection with such use.  Any such security services shall be solely for the benefit of Landlord’s property, and in no event shall Landlord be liable to Tenant for, and Tenant hereby releases Landlord and its agents and contractors from, liability for, any theft, loss or damage of or to Tenant’s property.  Landlord shall maintain the freight elevators in operable condition during the Move In Period, and shall promptly respond to any service request regarding the

6

freight elevators.  If availability of the freight elevator is interrupted due to a required repair, the Move In Period shall be extended by one day for each day of such interruption, and such interruption shall be considered a “Landlord Delay” for the purposes of Section 3.1(b) below, subject to the following sentence. If the elevator service company determines that service was required during the Move In Period due to excessive weight of freight, misuse of elevator doors, or similar misuse, and it is reasonably apparent that use or misuse by Tenant or Tenant’s contractors or vendors, rather than by Landlord or other tenants of the Project, resulted in the required service call, then Tenant shall pay the cost of the required repair and service call, and there shall be no extension of the Move In Period on account of any interruption in service of the freight elevator on account of such required service and such interruption shall not be a Landlord Delay.  During the Move In Period, Tenant shall be subject to all of the covenants in this Lease, except that Tenant’s obligation to pay Base Rent or Additional Rent shall commence on the Commencement Date or such other date specified in this Lease.  If Tenant commences its occupancy of the Premises prior to expiration of the Move In Period for the purpose of conducting Tenant’s business, then, notwithstanding anything to the contrary in this Section 2.3 or the provisions of the Basic Lease Information to the contrary, the Commencement Date of the Lease shall be the date Tenant so commenced its occupancy of the Premises for the purpose of conducting Tenant’s business.

ARTICLE 3.
TERM AND USE

3.1          Term.

(a)           Term; Commencement.  Except as otherwise provided in this Lease, the Term shall commence upon the Commencement Date, and shall continue in full force thereafter until the Expiration Date.  Except as otherwise provided in the Basic Lease Information, Tenant’s obligation to pay Base Rent shall commence on the first day of the first Rent Year.  Tenant’s other obligations under the Lease shall commence on the Commencement Date (except as expressly otherwise provided herein with respect to obligations arising earlier).  No delay in delivery of possession of the Premises shall operate to extend the term of this Lease or amend Tenant’s obligations under this Lease, and Landlord shall not be liable to Tenant for any loss or damage resulting therefrom, except as specifically provided in Section 3.1(b) below).

(b)           Delayed Commencement; Hold-Over Premium Reimbursement; Right to Terminate.  If Landlord’s Contractor constructs the Tenant Improvements, and the Tenant Improvements have not been Substantially Completed by January 1, 2007, as such date is extended pursuant to the provisions of this Section 3.1(b) (the “Credit Trigger Date”), then Landlord shall reimburse Tenant for the amount (the “Hold-Over Premium”) by which the holdover rent which Tenant is required to pay under the terms of its existing lease for holding over in its existing premises at 35 Stanford Street, San Francisco, California (the “Stanford Street Lease”) (calculated on a daily basis) exceeds the rental which is payable under the Stanford Street Lease during the final month of the term of the Stanford Street Lease (calculated on a daily basis) for the period commencing on the Credit Trigger Date and ending on the date immediately preceding the Commencement Date (or, if the Lease is terminated pursuant to the following provisions of this Section 3.1, ending on the termination date), provided that in no event shall the Hold-Over Premium exceed $57,753.50 per month, prorated on a daily basis.  Tenant represents and warrants that the hold over provision and base rent provision of the Stanford Street Lease are attached hereto as Exhibit F.  The Credit Trigger Date shall be extended by one (1) day for every two (2) days of delay in the delivery of possession of the Premises to Tenant that results from strikes, lock-outs, labor disputes, fire or other casualty, acts of God, Building Permit Delay (as defined below) or any other cause beyond the reasonable control of Landlord or Landlord’s Contractor (“Landlord Force Majeure”) and by one (1) day for each day of Tenant Delay (as defined in the Work Letter).  Such sums shall be payable by Landlord within ten (10) days after Landlord’s receipt of a rent invoice for such holdover rent from the landlord of 35 Stanford Street.  As used herein, a “Building Permit Delay” is any delay beyond April 28, 2006 in obtaining the required building permits for the Tenant Improvements, other than delays in issuance of MEP permits resulting from delays by the relevant Design-Build Subcontractor(s) (as defined in the Work Letter) (except to the extent such delay by the Design-Build Subcontractor results from Tenant’s failure to provide, by the dates specified in the Work Letter, the information required for the Design-Build Subcontractors to commence and complete their design, from Tenant’s Architect failure to cooperate with the Design-Build Subcontractors or to respond to inquiries from the Design-Build Subcontractors as and within the periods required by the Work Letter, or from other delays by Tenant or Tenant’s Architect).  Notwithstanding anything to the contrary herein, if Landlord’s Contractor constructs the Tenant Improvements, and the Tenant

7

Improvements have not been Substantially Completed by February 1, 2007 (as extended by Tenant Delay) (the “Trigger Date”) then Tenant may terminate this Lease by written notice to Landlord given within ten (10) days after the Trigger Date.

3.2          Extension Options.

(a)           Provided (i) there is no uncured Event of Default under the terms of this Lease at the time this extension option is exercised or at the commencement of the applicable Extension Term (as hereinafter defined), and (ii) Tenant is leasing at least 75,000 rentable feet of the Premises, Tenant shall have the option (the “Extension Options”) to extend the Term of this Lease for two additional periods of five (5) years each (each, an “Extension Period”), by giving written notice to Landlord of the exercise of such Extension Option (the “Extension Exercise Notice”) at least twelve (12) months prior to the expiration of the initial Term hereof, with respect to the initial Extension Option, and at least twelve (12) months prior to the expiration of the initial Extension Period, with respect to the second Extension Option.  Tenant shall have the right to exercise an Extension Option with respect to the entire Premises covered by the Lease as of the commencement of the applicable Extension Period, or with respect to less than the entire Premises then covered by the Lease (the “Reduced Premises”), provided the Reduced Premises shall include a minimum of seventy-five percent (75%) the Premises initially leased hereunder (as modified pursuant to Section 2.2 above, if applicable).  That portion of the Premises for which the Extension Option is not being exercised is referred to herein as the “Relinquished Premises”.  If the Reduced Premises shall be so configured that Landlord shall be required to separately demise any portion of the Reduced Premises from any portion of Relinquished Premises, Tenant shall reimburse Landlord for fifty percent (50%) of the reasonable cost of such demising. The Extension Exercise Notice shall designate whether Tenant is exercising the option with respect to the entire Premises then leased hereunder, or, if Tenant is exercising the Extension Option with respect to the Reduced Premises, in which event such Extension Exercise Notice shall clearly delineate the Reduced Premises.  If the Extension Exercise Notice does not indicate whether it is applicable to the entire Premises or to Reduced Premises, it shall be deemed to apply to the entire Premises.  The exercise of an Extension Option by Tenant shall be irrevocable, except as specifically set forth herein.  Upon such exercise, the Term of this Lease shall automatically be extended for the applicable Extension Period without the execution of any further instrument by the parties, provided that Landlord and Tenant shall, if requested by the other, execute and acknowledge an instrument confirming the exercise of the Extension Option.  The Extension Options shall terminate if not exercised precisely in the manner provided herein.  Any extension of the Term hereof shall be upon all the terms and conditions set forth in this Lease, except that: (i) Tenant shall have no further option to extend the term of this Lease beyond the second Extension Period, (ii) Landlord shall not be obligated to contribute funds toward the cost of any remodeling, renovation, alteration or improvement work in the Premises, (iii) commencing on the commencement date of the applicable Extension Period, the “Premises” shall consist of the Reduced Premises and Tenant’s Proportionate Share shall be calculated based on the Rentable Area of the Reduced Premises, and (iv) annual Base Rent for any such Extension Period shall be an amount equal to ninety-five percent (95%) of the “Fair Market Annual Rent” (as defined below) for the Premises (or Reduced Premises, as applicable).  Tenant shall surrender the Relinquished Premises, if any, to Landlord in the condition required by this Lease prior to the commencement of the applicable Extension Term.  If Tenant continues to occupy the Relinquished Premises to Landlord following commencement of the applicable Extension Term, the provisions of Section 15.2 of this Lease shall govern such continued occupancy.

(b)           “Fair Market Annual Rent” shall mean the “fair market” Base Rent at the time or times in question for the applicable space, taking into account the prevailing rents then being charged to new tenants for leases with terms equal to the Extension Period in comparable office buildings within the geographic area in which the Building is located and taking into account such amenities as existing improvements, the desirability of the location, location in the Building, size and quality of the space, included services and operating expense pass-throughs; and taking into account market tenant improvement allowances, free rent or other market allowances or concessions.

(c)           Landlord and Tenant shall endeavor to agree upon the Fair Market Annual Rent.  If they are unable to so agree within at least nine (9) months prior to the commencement of the Extension Period, then Tenant may elect, by written notice to Landlord given within ten (10) days following such date, to either rescind and revoke its exercise of the Extension Option or to have the Fair Market Annual Rent determined by appraisal pursuant to the provisions of this Section 3.2(c).  Failure to make either such election by such date shall be deemed an election to have Fair Market Annual Rent determined by appraisal.  If Tenant elects or is deemed to have elected

8

to have the Fair Market Annual Rent determined by appraisal, then on or before the date which is six (6) months prior to commencement of the applicable Extension Period, Landlord and Tenant each, at its cost and by giving notice to the other party, shall appoint a competent and disinterested full-time real estate appraiser with at least ten (10) years commercial appraisal experience in San Francisco or real estate broker with at least ten (10) years commercial leasing experience in San Francisco to appraise and set the Fair Market Annual Rent.  If either Landlord or Tenant does not appoint an appraiser or broker by such date, the single appraiser or broker appointed shall be the sole appraiser and shall set the Fair Market Annual Rent.  If two (2) appraisers or brokers are appointed by Landlord and Tenant as stated in this paragraph, they shall meet promptly and attempt to set the Fair Market Annual Rent.  If the two (2) appraisers or brokers are unable to agree within thirty (30) days after the second appraiser or broker has been appointed, they shall select a third appraiser (who shall be a real estate appraiser and not a broker) meeting the qualifications stated in this paragraph within ten (10) days thereafter.  If they are unable to agree on the third appraiser, either Landlord or Tenant, by giving ten (10) days notice to the other party, can apply to the then President of the Real Estate Board of San Francisco, or to the Presiding Judge of the Superior Court of the San Francisco County, for the selection of a third appraiser who meets the qualifications stated in this paragraph.  The third appraiser, however, selected, shall be a person who has not previously acted in any capacity for either Landlord or Tenant.  Within ten (10) days of the appointment of the third appraiser, the two (2) appraisers or brokers selected by the parties each shall submit such appraiser’s or broker’s determination of the Fair Market Annual Rent and, within thirty (30) days thereafter, the third appraiser shall select one of the two submissions of Fair Market Annual Rent that comes closest to such third appraiser’s determination of Fair Market Annual Rent, which selection shall be binding on the parties.  The party whose appraiser’s or broker’s determination of Fair Market Annual Rent is not selected shall bear the cost of appointing the third appraiser, if any, and of paying the third appraiser’s fee.

3.3          Termination Right; Partial Termination Right.  Tenant shall have certain rights to terminate this Lease early with respect to part or all of the Premises in accordance with the provisions of Article 19 below.

3.4          Use. Tenant shall use the Premises solely for the Permitted Use and for no other use or purpose whatsoever.

ARTICLE 4.
RENT AND SECURITY DEPOSIT

4.1          Base Rent.

(a)           Tenant shall pay the Base Rent to Landlord in accordance with the schedule set forth on the Basic Lease Information page and in the manner described below.  Upon execution of this Lease, Tenant shall pay one month’s Base Rent for the entire Premises at the rate first stated in the Basic Lease Information Page, and such Rent shall be applied to the Base Rent first due hereunder after any Rent abatement provided for herein.  Tenant shall pay the Base Rent plus, when applicable in accordance with Section 4.2 below, Tenant’s Proportionate Share of Increased Operating Cost, in monthly installments on or before the first day of each calendar month during the Term (subject to any rent abatement specifically provided in this Lease) and any extensions or renewals thereof, in advance without demand and without any reduction, abatement (except as specifically provided in this Lease), counterclaim or setoff, in lawful money of the United States, at Landlord’s address specified on the Basic Lease Information page or at such other address as may be designated by Landlord from time to time in the manner provided for giving notice under Section 17.11 hereof.

(b)           If the Term commences on other than the first day of a month, then the Base Rent provided for such partial month shall be prorated based upon a thirty (30)-day month and the prorated installment shall be paid on the first day of the calendar month next succeeding the Commencement Date together with the other amounts payable on that day.  If the Term terminates on other than the last day of a calendar month, then the Rent provided for such partial month shall be prorated based upon a thirty (30)-day month and the prorated installment shall be paid on the first day of the calendar month in which the date of termination occurs.

9

4.2          Tenant’s Proportionate Share of Increased Operating Cost and Real Estate Taxes.

(a)           Commencing with the first day of the calendar year following the Base Year identified on the Basic Lease Information page, and continuing through the remainder of the Term, Tenant shall pay to Landlord Tenant’s Proportionate Share of the total dollar increase, if any, in: (i) Operating Cost attributable to each Computation Year over Base Expenses, and (ii) Real Estate Taxes over Base Real Estate Taxes.  As used herein “Base Real Estate Taxes” shall mean Real Estate Taxes assessed during the Base Year.

(b)           During the last month of each calendar year preceding a Computation Year (or as soon thereafter as practicable), Landlord shall give Tenant notice of Landlord’s estimate of the amount payable by Tenant under Section 4.1(a) for the following Computation Year.  On or before the first day of each month during the following Computation Year, Tenant shall pay to Landlord one-twelfth (1/12) of such estimated amount, provided that if Landlord fails to give such notice in the last month of the prior year, then Tenant shall continue to pay on the basis of the prior year’s estimate until the first day of the calendar month next succeeding the date such notice is given by Landlord; and from the first day of the calendar month following the date such notice is given, Tenant’s payments shall be adjusted so that the estimated amount for that Computation Year will be fully paid by the end of that Computation Year.  If at any time or times Landlord determines that the amount payable under Section 4.1(a) for the current Computation Year will vary from its estimate given to Tenant, Landlord, by not less than ten (10) business days’ notice to Tenant, may revise its estimate for such Computation Year, and subsequent payments by Tenant for such Computation Year shall be based upon such revised estimate.

(c)           Within one hundred twenty (120) days following the end of each Computation Year, Landlord shall deliver to Tenant a statement of amounts payable under Section 4.1(a) for such Computation Year prepared by Landlord (an “Annual Statement”).  If such Annual Statement shows an amount owing by Tenant that is less than the payments for such Computation Year previously made by Tenant, Landlord shall credit such amount to the next payment(s) of Rent falling due under this Lease.  If such Annual Statement shows an amount owing by Tenant that is more than the estimated payments for such Computation Year previously made by Tenant, Tenant shall pay the deficiency to Landlord within thirty (30) days after delivery of such statement.  The respective obligations of Landlord and Tenant under this Section 4.2(c) shall survive the Expiration Date, and, if the Expiration Date is a day other than the last day of a Computation Year, the adjustment in Tenant’s Proportionate Share of Increased Operating Cost pursuant to this Section 4.2(c) for the Computation Year in which the Expiration Date occurs shall be prorated in the proportion that the number of days in such Computation Year preceding the Expiration Date bears to three hundred sixty-five (365).

(d)           Landlord shall have the same remedies for a default in the payment of Tenant’s Proportionate Share of Increased Operating Cost and Real Estate Taxes as for a default in the payment of Base Rent.

(e)           Notwithstanding anything to the contrary in this Section 4.2., if a sale of the Building occurs during the initial Term of this Lease, then Tenant’s Proportionate Share of increases in Real Estate Taxes shall be limited to the Tenant’s Proportionate Share of increases in Real Estate Taxes that would have resulted absent such sale. For purposes of calculating the Real Estate Taxes that would have resulted absent such sale, the taxing rate used shall be the rate in effect just prior to such sale as increased annually by the maximum amount allowable had such sale not occurred.

(f)            Tenant’s Audit Rights.  Tenant shall have the right, by written notice to Landlord given within one hundred twenty (120) days after Tenant’s receipt of the annual statement, to request reasonable back-up documentation for specific Operating Costs and Real Estate Taxes shown on such annual statement, or specific categories thereof, and Landlord shall provide Tenant with (or make available to Tenant at Landlord’s offices) reasonable supporting documentation for any expenses or category of expenses questioned by Tenant in such notice.  If Tenant does not give Landlord such request within such time, Tenant shall have waived its right to dispute the Annual Statement.  Promptly after the receipt of such written request from Tenant, Landlord and Tenant shall endeavor in good faith to resolve Tenant’s questions or dispute.  If such efforts do not succeed within ninety (90) days after Tenant’s initial written request, Tenant shall have the right to cause a nationally recognized independent certified public accountant or a nationally recognized commercial real estate company designated by Tenant, to be paid on an hourly and not a contingent fee basis, to audit the items questioned by Tenant in its original notice contesting the annual statement, provided that Tenant (i) notifies Landlord in writing of Tenant’s intention to

10

exercise such audit right within sixty (60) days after the expiration of such ninety (90)-day period, (ii) actually begins such audit within sixty (60) days after the notice from Tenant to Landlord advising Landlord that Tenant will require an audit (provided that such 60-day period within which the audit must be commenced shall be extended by the length of any delay in the commencement of the audit that is caused by Landlord) and (iii) diligently pursues such audit to completion as quickly as reasonably possible.  Landlord agrees to make available to Tenant’s auditors, at Landlord’s office in San Francisco, the books and records relevant to the audit for review and copying, but such books and records may not be removed from Landlord’s offices.  Tenant shall bear all costs of such audit, including Landlord’s actual copying costs and personnel costs, if any, incurred in connection with such audit, except that, if the audit (as conducted and certified by the auditor) shows an aggregate overstatement of Operating Costs of five (5%) or more, and Landlord’s auditors concur in such findings (or, in the absence of such concurrence, such overstatement is confirmed by a court of competent jurisdiction or such other dispute resolution mechanism as to which the parties mutually agree in writing), then Landlord shall bear all costs of the audit (including the cost of the dispute resolution mechanism).  If the agreed or confirmed audit shows an underpayment of Operating Costs by Tenant, Tenant shall pay to Landlord, within ten (10) business days after the audit is agreed to or confirmed, the amount owed to Landlord, and, if the agreed or confirmed audit shows an overpayment of Operating Costs by Tenant, Landlord shall reimburse Tenant for such overpayment within thirty (30) days after the audit is agreed to or confirmed.  Notwithstanding anything to the contrary set forth above, Tenant’s audit rights under this Section 4.2. shall be conditioned upon (i) Tenant having paid the total amounts billed by Landlord under this Section 4.2 (including, without limitation, the contested amounts) and (ii) Tenant and Tenant’s auditor executing, prior to the commencement of the audit, a confidentiality agreement in form and substance reasonably satisfactory to Landlord and Tenant in which Tenant and Tenant’s auditor shall agree to keep confidential, and not disclose to any other party (except to the limited extent expressly provided in the confidentiality agreement), the results of any such audit or any action taken by Landlord in response thereto.

4.3          Operating Cost.

(10)         Amortization (together with reasonable financing charges) of (A) capital improvements made to the Project subsequent to the date of this Lease which are designed to improve the operating efficiency of the Project (provided, however, that, the costs thereof may only be included in Operating Costs if, at the time such costs were incurred, Landlord reasonably estimated that the annual saving in Operating Costs that would result from such expenditure would be equal to or exceed the annual amortized amount of the cost to be included in Operating Costs pursuant to this item (10))or (B) capital improvements made to the Project subsequent to the date of this Lease which may be required by governmental authorities, including those improvements required for energy conservation and for the benefit of individuals with disabilities (provided that such amortization period shall be within the range used to amortize such costs by landlords of other first-class office buildings in the geographic area of the Premises in accordance with generally accepted property management practices).  Notwithstanding the foregoing, the amortization period used with respect to (B) above shall not be less than the lesser of (i) one year multiplied by the amount obtained by dividing the cost of such capital improvement by $50,000 and (ii) the reasonable useful life of such capital improvement.

(11)         All property management fees, not to exceed four percent (4%) of gross rents of the Project.

(b)           Notwithstanding the provisions of Section 4.3(a) above to the contrary, Operating Cost shall exclude (i) costs arising from the violation of any applicable law by Landlord, any other occupant of the Project, or their respective agents, employees or contractors, except to the extent such costs reflect costs that would have been incurred by Landlord absent such violation, (ii) the capital cost of repairs and other work occasioned by insured casualty, except for the deductible amounts set forth in Section 4.3(a)(7) above, (iii) any repairs of a capital nature necessary to cure defects in the initial construction of the Project and costs of compliance with applicable building codes to the extent the Project does not comply with such building codes as of the date of this Lease and such compliance is required as of the date of this Lease, (iv) the cost (including permits, licenses and inspection fees) of decorating, improving for tenant occupancy, renovating, painting or redecorating portions of the Project to be demised to tenants, (v) costs, fees and expenses incurred in connection with lease negotiations or lease disputes with current or prospective Project tenants, (vi) penalties or other costs incurred due to a violation by Landlord, as determined by written admission, stipulation, final judgment or arbitration award, of any of the terms and conditions of this Lease or any other lease relating to the Project except to the extent such costs reflect costs that would have been incurred by Landlord absent such violation, (vii) increases in insurance costs directly attributable to the activities of another tenant in the Project, (viii) the cost of any Hazardous Material abatement or removal activities, provided, however, Operating Cost may include minor costs attributable to those actions taken by Landlord to comply with any laws, rules and regulations incidental to with the ordinary operation and maintenance of the Project, including costs incurred in removing limited amounts of Hazardous Materials from the Building when such removal is directly related to such ordinary maintenance and operation, (ix) interest, charges, and fees incurred on

(c)           Adjustment to Base Year and Other Operating Costs.  Notwithstanding any other provision of this Lease to the contrary, (i) in the event that the Project is not fully occupied during any year of the Term, including the Base Year, an adjustment shall be made in computing Operating Cost for such year so that Operating Cost shall be computed as though the Project had been 100% occupied during such year, and (ii) with respect to types of insurance which Landlord does not carry during the Base Year but obtains in a calendar year subsequent to the Base Year (e.g., earthquake insurance), for purposes of calculating Tenant’s payments pursuant to Section 4.2 for such subsequent calendar year, Operating Cost for the Base Year shall be deemed increased by the premiums attributable to such insurance in such calendar year, as such premiums shall be decreased to reflect any percentage increase in the CPI (as defined below) from the CPI Base (as defined below) to the CPI in effect for January 1^st of such later calendar year).  Further, during the Base Year and any period of Initial Base Rent Abatement as provided in the Basic Lease Information, there shall be included in Operating Cost management fees calculated as if the gross revenues of the Project for such period included Base Rent for the Premises at the rate initially payable under this Lease.

(d)           The term “CPI” as used herein means the Consumer Price Index for All Urban Consumers (1982-84 = 100) San Francisco-Oakland-San Jose, California, All Items, published by the Bureau of Labor Statistics of the U.S. Department of Labor.  If the Bureau of Labor Statistics ceases to publish the above Index, or is the above Index is otherwise renamed, discontinued or superseded, the parties agree that the Bureau of Labor Statistics or any successor governmental agency thereto will be the sole judge of the comparability of successive indices, but if no such agency supplies and designates a comparable index, or if no succeeding index is published, then the calculations under this Lease based on the CPI shall be made using the most closely comparable statistics on the purchasing power of the consumer dollar as published by a responsible financial authority selected by Landlord.  The term “CPI Base” as used herein means the CPI in effect as of January 1, 2006.

4.4          Real Estate Taxes.  “Real Estate Taxes” shall include: all real estate or personal property taxes, possessory interest taxes, business or license taxes or fees, service payments in lieu of such taxes or fees, annual or periodic license or use fees, excises, transit charges, housing fund assessments, open space charges, assessments, bonds, levies, fees or charges, general and special, ordinary and extraordinary, unforeseen as well as foreseen, of any kind which are assessed, levied, charged, confirmed or imposed by any public authority upon the Project (or any portion or component thereof), its operations, this Lease, or the Rent due hereunder (or any portion or component thereof) and any tax or charge which replaces or is in addition to any of such above-described real estate taxes, except: (i) inheritance or estate taxes imposed upon or assessed against the Project, or any part thereof or interest therein, and (ii) Landlord’s personal or corporate income, gift or franchise taxes. If any Real Estate Taxes are payable in installments without penalty (except for reasonable interest), then for the purpose hereof (regardless of whether Landlord elects to pay same in installments) Real Estate Taxes for any calendar year occurring during the term shall include only those installments, together with interest, that would have become due if Landlord opted to pay same in the maximum number of installments permitted.

4.5          Late Charge.  If any payment required to be made by Tenant under this Lease is not received by Landlord within five (5) days of the date the same is due, Tenant shall pay to Landlord an amount equal to five percent (5%) of the delinquency.  The parties agree that Landlord would incur costs not contemplated by this Lease by virtue of such delinquencies, including without limitation administrative, collection, processing and accounting

13

expenses, the amount of which would be extremely difficult to compute, and the amount stated herein represents a reasonable estimate thereof.  Acceptance of such late charge by Landlord shall in no event constitute a waiver of Tenant’s breach or default with respect to such delinquency, or prevent Landlord from exercising any of Landlord’s other rights and remedies.  Notwithstanding the foregoing, Tenant shall be entitled to one (1) notice and three (3)-day cure period during each twelve (12) month period before any late charges accrue.

4.6          Interest on Past-Due Obligations.  Except as expressly otherwise provided in this Lease, any Rent due Landlord hereunder, other than late charges, which is not received by Landlord within five (5) days of the date on which it was due until the date paid, shall bear interest from the day it was due at the lesser of 18% per annum or the maximum rate then allowed by law, in addition to the late charge provided for in Section 4.5.

4.7          Security Deposit.

(a)           Security Deposit.  Concurrently with the execution of this Lease by Tenant, Tenant shall pay to Landlord the Estimated Deposit Amount, which shall be held as a Security Deposit as security for the full and faithful performance of Tenant’s obligations under this Lease.  Upon determination of the Rentable Area of the Premises pursuant to Section 1.18 above, Tenant shall pay Landlord or Landlord shall refund to Tenant, as applicable, the difference between the Estimated Deposit Amount and the amount of the Security Deposit established pursuant to Section 1.18.  If at any time during the Term, Tenant shall be in default beyond any applicable notice and cure period in the payment of Rent or for any other reason, Landlord may use, apply or retain all or part of the Security Deposit to the extent necessary for payment of any amount due Landlord or to cure such default or to reimburse or compensate Landlord for any liability, loss, cost, expense or damage (including attorneys’ fees) which Landlord may suffer or incur by reason of Tenant’s defaults.  If Landlord uses or applies all or any part of the Security Deposit, Tenant shall, within ten (10) days of demand therefor, pay to Landlord a sum sufficient to restore the Security Deposit to the full amount required by this Lease.  Upon expiration of the Term or earlier termination of this Lease and after Tenant has vacated the Premises, Landlord shall return the Security Deposit to Tenant, reduced by such amounts as may be required by Landlord to remedy defaults on the part of Tenant in the payment of Rent, to repair damages to the Premises caused by Tenant and to clean the Premises.  The portion of the Security Deposit not so required shall be paid over to Tenant (or, at Landlord’s option, to the last assignee of Tenant’s interest in this Lease) within thirty (30) days after expiration of the Term or earlier termination hereof.  Landlord shall hold the Security Deposit for the foregoing purposes; provided, however, that Landlord shall have no obligation to segregate the Security Deposit from its general funds or to pay interest in respect thereof.  No part of the Security Deposit shall be considered to be held in trust, or to be prepayment of any monies to be paid by Tenant under this Lease.

(b)           Recalculation of Security Deposit.  If Tenant elects to modify the size of the Premises pursuant to the provisions of Section 2.2 above, the Security Deposit specified in the Basic Lease Information page shall be recalculated to be an amount equal to (a) the number of square feet of Rentable Area of the Premises (as so modified) multiplied by (b) $12.00, and within ten (10) days of such recalculation Landlord shall refund to Tenant the amount by which the Security Deposit then held by Landlord exceeds the recalculated Security Deposit, or Tenant shall deposit with Landlord additional monies in the amount by which the recalculated Security Deposit exceeds the Security Deposit then held by Landlord, as applicable.

(c)           Reduction in Security Deposit.  Notwithstanding the foregoing provisions of this Section 4.7, provided that no Event of Default (or default that subsequently matures into an Event of Default) by Tenant under this Lease has occurred on or prior to the second (2^nd) anniversary of the Commencement Date, then effective as of such date the Security Deposit amount required hereunder shall be reduced to an amount equal to one month’s monthly Base Rent at the rate payable under this Lease during the Tenth Rent Year (the “Reduced Security Deposit Amount”), and Landlord shall promptly return to Tenant the balance of the Security Deposit which exceeds the Reduced Security Deposit Amount upon Tenant’s request therefor; provided, however, that in no event shall any such return be construed as an admission by Landlord that Tenant has performed all of its covenants and obligations hereunder.

(d)           Letter of Credit.  In lieu of a cash Security Deposit, the Security Deposit may be delivered by Tenant to Landlord in the form of an irrevocable and unconditional letter of credit (the “Letter of Credit”) governed by the Uniform Customs and Practice for Documentary Credits (1993 revisions), International

14

Chamber of Commerce Publication No. 500, as revised from time to time in form and substance reasonably satisfactory to Landlord.  The Letter of Credit shall be held and applied by Landlord in the same manner as a cash Security Deposit as provided above in Section 4.7(a) above and on the terms and conditions of this Section 4.7(d). The Letter of Credit may be drawn upon by Landlord upon presentation of Landlord’s sight draft accompanied by the Letter of Credit and Landlord’s signed statement that Tenant is in default under the Lease and Landlord is entitled to draw on the Letter of Credit pursuant to this Lease, and with no other conditions.  Tenant shall maintain the Letter of Credit through the date which is thirty (30) days following the expiration of the Term (including any extension thereof).  The Letter of Credit shall be issued by a major commercial bank reasonably acceptable to Landlord.  The Letter of Credit shall expressly state that the Letter of Credit and the right to draw thereunder may be transferred or assigned by Landlord to any successor or assignee of Landlord under the Lease without recourse, and in no event shall Landlord be required to pay any fees or charges in connection with any such transfer.  The Letter of Credit shall permit partial and multiple draws.  The Letter of Credit shall have a term of not less than one (1) year and provide that it will be automatically renewed unless the issuer provides Landlord with written notice of non-renewal at the notice address herein at least sixty (60) days prior to the expiration thereof.  If Tenant fails to furnish Landlord with a replacement Letter of Credit pursuant to the terms and conditions of this section by the date which is than thirty (30) days prior to the expiration of the Letter of Credit, then Landlord shall have the right to draw the full amount of the Letter of Credit, by sight draft, and shall hold the proceeds of the Letter of Credit as a cash Security Deposit pursuant to the terms and conditions of this Section 4.7. Any draw on the Letter of Credit shall not constitute a waiver of any other rights of Landlord with respect to such default or failure to perform. At the expiration or termination of this Lease, and after Tenant has vacated the Premises, Landlord shall return to Tenant the Letter of Credit then held by Landlord, if applicable; provided that if Tenant is then in default Landlord may first draw on such Letter of Credit an amount equal to one hundred and fifty percent (150%) of the amount sufficient to cure such default, as reasonably estimated by Landlord and upon cure of such default Landlord shall return the unused balance of the amount so drawn to Tenant; provided, however, that in no event shall any such return of the Letter of Credit or the balance of the amount drawn by Landlord be construed as an admission by Landlord that Tenant has performed all of its covenants and obligations hereunder and in no event shall Landlord’s estimate of the amount required to cure such default limit Tenant’s obligations under this Lease.

4.8          Utilities.  Commencing on the first day of the Move In Period and continuing throughout the Lease term, Tenant shall pay for all electrical utilities and telephone service supplied to the Premises, together with any taxes thereon.  Tenant shall contract directly with the utility company and the telephone company, as the case may be, for the provision of electricity and telephone services to the Premises.

(6)           Tenant shall remove the New Sign prior to the expiration of the Lease Term (and Tenant shall remove the New Sign promptly upon, and in all events within 20 days after, Landlord’s request, if Tenant does not actually use and occupy at least fifty percent (50%) of the Premises initially leased hereunder to conduct business as “Advent Software” or the business of an Affiliate Transferee or in the event of any uncured Event of Default by Tenant under the Lease) (or, at Landlord’s election, Landlord shall have the right to remove such signage at Tenant’s expense, and Tenant shall reimburse Landlord costs thereof reasonably incurred by Landlord within thirty (30) days after demand);

(7)           Tenant shall promptly repair any damage to the Building caused as a result of such signage, including, without limitation, the installation or removal thereof (or, at Landlord’s election, Landlord

17

shall have the right to perform such repair at Tenant’s expense, and Tenant shall reimburse Landlord for the cost thereof within thirty (30) days after demand); and

(8)           Landlord shall have the right temporarily to remove or relocate the New Sign as may be necessary in connection with any maintenance, repair or restoration work

Tenant’s right to Building exterior signage shall be exclusive to Tenant during the period commencing on the Commencement Date and ending on the first date that Tenant leases less than 92,000 square feet of space pursuant to this Lease (the “Special Occupancy Level Reduction Date”), and the exclusive nature of such right shall terminate forever on the Special Occupancy Level Reduction Date.

5.5          Repair Obligation.  Landlord’s shall maintain and repair in good condition and working order: (i) the structural portions of the Building; (ii) the exterior walls of the Building, including exterior glass and glazing (including the sealing thereof); (iii) the roof (including the sealing thereof); (iv) base Building mechanical, electrical, plumbing and life safety systems; (v) the Building’s cooling tower, boiler, and closed circuit cooling tower and hot water system; (vi) the water-source heat pump unit(s) in the Premises connected to the Building’s closed circuit cooling tower and hot water system; (vii) the Common Areas; (viii) the Project parking garage; (ix) landscaped areas; and (x) the elevators.  Landlord shall not be liable for any failure to make any such repairs or to perform any maintenance unless such failure shall persist for an unreasonable time after written notice of the need of such repairs or maintenance is given to Landlord by Tenant.  However, Landlord shall not have any obligation to repair damage caused by Tenant, its agents, employees, contractors, invitees or licensees, and Tenant shall pay the costs of such repairs subject to Section 11.5.  Further, Landlord shall have the right, but not the obligation, to undertake work of repair which Tenant is required to perform under this Lease and which Tenant fails or refuses to perform in a timely and efficient manner.  Tenant shall reimburse Landlord upon demand, as Additional Rent, for all costs incurred by Landlord in performing any such repair for the account of Tenant, together with an amount equal to ten percent (10%) of such costs to reimburse Landlord for its administration and managerial effort.  Except as specifically set forth in this Lease, Landlord shall have no obligation whatsoever to maintain or repair the Premises or the Project.  The parties intend that the terms of this Lease govern their respective maintenance and repair obligations.  Landlord reserves the right from time to time, so long as reasonable access and basic services to the Premises remain available, to install, use, maintain, repair, relocate and/or replace pipes, conduits, wires and equipment within and around the Building and to do and perform such other acts and make such other changes in, to or with respect to the Building or the Project (including without limitation with respect to the driveways, garage, walkways and entrances to the Project) as Landlord may, in the exercise of sound business judgment, deem to be appropriate.  In connection therewith, Landlord shall have the right to close temporarily any of the Common Areas so long as reasonable access to the Premises remains available.  In exercising these rights, Landlord shall make commercially reasonable efforts to minimize the impact on Tenant’s use and occupancy of the Premises.  Landlord shall not be liable to Tenant for any interruption of Tenant’s business or inconvenience caused due to any work performed in the Premises or in the Building pursuant to Landlord’s rights and obligations under this Lease.  Tenant expressly waives the benefit of any statute now or hereafter in effect to the extent it is inconsistent with the terms of this Lease with respect to such obligations or which affords Tenant the right to make repairs at the expense of Landlord.

5.6          Quiet Enjoyment.  While paying the rental and performing its other covenants and agreements contained in this Lease, Tenant shall peaceably and quietly have, hold and enjoy the Premises for the Term without hindrance or molestation from Landlord subject to the terms and provisions of this Lease.  Landlord shall not be liable for any interference or disturbance by other tenants or third persons, nor shall Tenant be released from any of the obligations of this Lease because of such interference or disturbance.  Landlord, however, shall use reasonable efforts to cause such other tenants to cease any such unreasonable interference.

5.7          Landlord Compliance with Law.   Landlord shall be responsible for causing the following to comply with all laws required for Tenant to build out, occupy and use the Premises for the purposes leased (including, without limitation, the requirements regarding accessibility and parking) as of the date of delivery of the Premises to Tenant:  the common area restrooms, restrooms located within the Premises as of the Effective Date (except to the extent alterations thereto are required due to the occupancy of the Premises by more than one person per 138 square feet of Rentable Area of the Premises on any floor or due to the particular use by Tenant), the common areas of the Building that are reasonably anticipated to be in Tenant’s path of travel (including common area entry doors and entry doors to the Premises, to the extent such doors are not included as elements of the Tenant

18

Improvements), the parking garage, the elevators in the Building, the Building’s life safety system, electrical and telecommunications rooms in the Building (excluding electrical and telecommunications rooms located within the Premises which exclusively serve the Premises), and the main boiler room or rooms serving the Building

ARTICLE 6.
TENANT’S COVENANTS

6.1          Payments by Tenant.  Tenant shall pay Rent at the times and in the manner provided in this Lease.  All obligations of Tenant hereunder to make payments to Landlord shall constitute Rent and failure to pay the same when due shall give rise to the rights and remedies provided for in Article 14, subject to applicable notice and cure periods, if any.  If there is more than one Tenant, the obligations imposed upon Tenant under this Lease shall be joint and several.

6.2          Taxes on Personal Property and Tenant Improvements.  In addition to, and wholly apart from its obligation to pay Tenant’s Proportionate Share of Increased Operating Costs, Tenant shall be responsible for, and shall pay prior to delinquency, all taxes or governmental service fees, possessory interest taxes, fees or charges in lieu of any such taxes, capital levies, and any other charges imposed upon, levied with respect to, or assessed against Tenant’s personal property, on the value of the Tenant Improvements (if any) and on its interest pursuant to this Lease.  To the extent that any such taxes are not separately assessed or billed to Tenant, Tenant shall pay the amount thereof as invoiced to Tenant by Landlord.

6.3          Repairs by Tenant.  Tenant shall be obligated to maintain and repair the Premises to keep the same at all times in good order, condition and repair, and, upon expiration of the Term, to surrender the same to Landlord in the same condition as on the Commencement Date, reasonable wear and tear, taking by condemnation, and damage that is Landlord’s responsibility under Section 5.5 not caused by Tenant, its agents, employees, contractors, invitees and licensees, excepted, and damage from casualty to improvements other than the Tenant Improvements and other improvements paid for from allowances provided by Landlord excepted.  Tenant’s obligations shall include, without limitation, the obligation to maintain and repair all walls, floor coverings, ceilings and fixtures, and to repair all damage caused by Tenant, its agents, employees, contractors, invitees and others using the Premises with Tenant’s express or implied permission.  Tenant, at Tenant’s sole cost and expense, shall enter into a contract with a vendor approved by Landlord to provide for periodic inspection and maintenance of any dedicated or supplemental heating, ventilating and/or air conditioning units or systems in the Premises, and shall maintain such contract in force throughout the Term of this Lease.  Upon Landlord’s request, Tenant shall deliver a copy of such maintenance contract to Landlord, and shall at Landlord’s request made from time to time provide Landlord with copies of inspection and maintenance reports made pursuant to such contracts.  Any work of repair and maintenance performed by or for the account of Tenant by persons other than Landlord shall be performed by contractors approved by Landlord and in accordance with such reasonable procedures as Landlord shall from time to time establish.  Tenant shall give Landlord prompt notice of any damage to or defective condition in any part of the Building’s mechanical, electrical, plumbing, life safety or other system servicing, located in or passing through the Premises.  Tenant acknowledges that it is generally understood that mold spores are present essentially everywhere and that mold can grow in almost any moist location.  Tenant acknowledges the necessity of good housekeeping, ventilation, and moisture control (especially in kitchens, janitor’s closets, bathrooms, break rooms and around outside walls) for mold prevention, and execution of this Lease constitutes acknowledgement by Tenant that control of moisture and mold prevention are integral to Tenant’s obligations under this Lease. Tenant agrees to immediately notify Landlord if it observes mold/mildew and/or moisture conditions (from any source, including leaks), and allow Landlord to evaluate and make recommendations and/or take appropriate corrective action.  Landlord shall deliver the Premises free of mold or mildew, which Tenant shall verify to Tenant’s satisfaction by inspection or other means.  Tenant relieves Landlord from any liability for any damages to property caused by or associated with moisture or the growth of or occurrence of mold or mildew in the Premises after the delivery of the Premises to Tenant.  In the event of a conflict between the provisions of this Section 6.3 and the provisions of Article 13 below, the provisions of Article 13 shall control.

6.4          Waste.  Tenant shall not commit or allow any waste or damage to be committed in any portion of the Premises or the Project.

19

6.5          Compliance With Laws and Insurance Standards.  Tenant shall not occupy or use, or permit any portion of the Premises to be occupied or used in a manner that violates any applicable law, ordinance, rule, regulation, order, permit, covenant, easement or restriction of record relating in any manner to the Project, or for any business or purpose which is disreputable, reasonably objectionable or productive of fire hazard.  Tenant shall not do or permit anything to be done which would result in the cancellation of, or in any way increase the cost of, the property insurance coverage on the Project and/or its contents.  If Tenant does or permits anything to be done which increases the cost of any insurance covering or affecting the Project (other than the normal occupancy of the Premises for the Permitted Use), then Tenant shall reimburse Landlord, upon demand, as Additional Rent, for such additional costs.  Landlord shall deliver to Tenant a written statement setting forth the amount of any such insurance cost increase and showing in reasonable detail the manner in which it has been computed.  Tenant shall, at Tenant’s sole cost and expense, comply with all laws, ordinances, rules, regulations and orders (state, federal, municipal or promulgated by other agencies or bodies having or claiming jurisdiction) related to the use, condition or occupancy of the Premises now in effect or which may hereafter come into effect including, but not limited to, accessibility and use by individuals with disabilities.  If anything done by Tenant in its particular use or occupancy of the Premises shall create, require or cause imposition of any requirement by any public authority for structural or other upgrading of or alteration or improvement to the Project, Tenant shall, at Landlord’s option, either perform the upgrade, alteration or improvement at Tenant’s sole cost and expense or reimburse Landlord upon demand, as Additional Rent, for the cost to Landlord of performing such work.  The judgment of any court of competent jurisdiction or the admission by Tenant in any action against Tenant, whether Landlord is a party thereto or not, that Tenant has violated any law, ordinance, rule, regulation, order, permit, covenant, easement or restriction shall be conclusive of that fact as between Landlord and Tenant.

6.6          Limitation on Tenant’s Compliance Obligations.  Notwithstanding the provisions of Section 6.5 above to the contrary, (A) Tenant shall not be required to perform any changes to the Base Building (as defined below) unless such changes are caused or triggered by (i) Tenant’s alterations or improvements to the Premises (other than the Tenant Improvements), (ii) Tenant’s particular use of the Premises (as opposed to Tenant’s use of the Premises for general office purposes in a normal and customary manner), including, if applicable, rooms of size or configuration not typical for general office use in a Class A office building in the San Francisco South of Market Street area or providing for occupancy in excess of one (1) person per 138 square feet of rentable area of the Premises on any floor, or (iii) Tenant’s particular employees or employment practices, (B) Tenant shall not be required to perform any alterations or improvements to or improvements to portions of the Project systems located outside of the Premises, or to other components of the Base Building located outside of the Premises, by reason of the Tenant Improvements unless such changes are caused or triggered by (i) the failure of Tenant’s architect to design the Tenant Improvements in compliance with applicable building codes and other legal requirements, or (ii) inclusion in the Tenant Improvements of improvements which are not normal and customary general office improvements (such as, without limitation, internal stairwells, library, file, computer or meeting rooms, classroom facilities (other than normal and customary conference rooms) or areas requiring floor reinforcement or enhanced systems requirements), and (C) provided that Tenant’s architect shall have prepared the Final Plans in compliance with applicable building codes and other legal requirements, Tenant shall not be required to perform any work to the Premises caused or triggered solely by reason of Landlord’s failure to construct the Tenant Improvements in accordance with the Final Plans (as defined in the Work Letter).  As used in this Section 6.6, “Base Building” shall mean structural portions of the Project (including exterior walls, roof, foundation, floor slabs and core of the Project, whether or not comprising a part of the Premises), or to Building systems (including, without limitation, elevator, plumbing, heating, electrical, security, and life safety), and the alterations, improvements and other work which Tenant is specifically excused from performing pursuant to the provisions of this Section 6.6 are referred to as “Excused Work.”

6.7          Rules and Regulations.  Tenant shall comply with the rules and regulations for the Project attached as Exhibit D and such reasonable and nondiscriminatory amendments thereto as Landlord may adopt from time to time with prior notice to Tenant.  Landlord shall apply such rules and regulations in a nondiscriminatory manner.

6.8          No Nuisance; No Overloading.  Tenant shall use and occupy the Premises, and control its agents, employees, contractors, invitees and visitors, in such manner so as not to create any nuisance, or interfere with, annoy or disturb (whether by noise, odor, vibration or otherwise) any other tenant or occupant of the Project or Landlord in its operation of the Project.  Tenant shall not place or permit to be placed any loads upon the floors,

20

walls or ceilings in excess of the maximum designed load specified by Landlord or which might damage the Premises, the Building, or any portion thereof.

6.9          Furnishing of Financial Statements; Tenant’s Representations.  In order to induce Landlord to enter into this Lease, Tenant agrees that it shall promptly furnish Landlord, from time to time, within ten (10) business days of receipt of Landlord’s written request therefor, with financial statements in form and substance reasonably satisfactory to Landlord reflecting Tenant’s then-current financial condition; provided, however, that unless the Project is then for sale or subject to refinancing, or an Event of Default has occurred and is continuing, Landlord shall not exercise its rights under this Section 6.8 more frequently than one (1) time per calendar year.  Tenant shall not be required to provide financial statements pursuant to this Section 6.8 during any period in which Tenant has outstanding a class of publicly traded securities and is filing with the Securities and Exchange Commission, on a regular basis, Forms 10Q and 10K and any other periodic filings required under the Securities Exchange Act of 1934, as amended.  Tenant represents and warrants that all financial statements, records and information furnished by Tenant to Landlord in connection with this Lease are true, correct and complete in all respects.

ARTICLE 7.
ASSIGNMENT OR SUBLEASE

7.1          No Assignment Without Consent.  Tenant shall not voluntarily or by operation of law assign, transfer or encumber (collectively “Assign”) or sublet all or any part of Tenant’s interest in this Lease or in the Premises without Landlord’s prior written consent, which shall not be unreasonably withheld subject to the terms of this Article 7.  A change in the control of Tenant in a transaction or a series of transactions shall not be deemed an assignment hereunder, unless the essential purpose of such change of control is to transfer the tenant’s interest in this Lease without actually conveying a substantial, active, ongoing business, in which event such change of control shall constitute an assignment requiring Landlord’s consent.  The following transfers shall not be included in determining whether control has been transferred: the transfer of outstanding capital stock or other listed equity interests by persons or parties other than “insiders” within the meaning of the Securities Exchange Act of 1934, as amended, through the “over the counter” market or any recognized national or international securities exchange (including, without limitation, Nasdaq).

7.2          Notice of Assignment.  If Tenant desires to Assign this Lease or any interest herein or sublet the Premises or any part thereof, Tenant shall give Landlord written notice of such intent.  Tenant’s notice shall specify the date the proposed assignment or sublease would be effective and be accompanied by information pertinent to Landlord’s determination as to the financial and operational responsibility and appropriateness of the proposed assignee or subtenant, including, without limitation, its name, business and financial condition, financial details of the proposed transfer, the intended use (including any modification) of the Premises, and exact copies of all of the proposed agreement(s) between Tenant and the proposed assignee or subtenant.  Tenant shall promptly provide Landlord with (i) such other or additional information or documents reasonably requested (within ten (10) days after receiving Tenant’s notice) by Landlord, and (ii) an opportunity to meet and interview the proposed assignee or subtenant, if requested by Landlord.

7.3          Landlord Consent.  Landlord shall have a period of ten (10) days following such interview and receipt of such additional information (or twenty (20) days from the date of Tenant’s original notice if Landlord does not request additional information or an interview) within which to notify Tenant in writing that Landlord elects either (i) to reasonably decline Tenant’s request to assign or sublease (taking into account Landlord’s obligation not to unreasonably withhold its consent), in which event this Lease shall remain in full force and effect; (ii) to terminate this Lease as to the space so affected as of the effective date specified by Tenant, in which event Tenant will be relieved of all obligations hereunder as to such space arising after the effective date of such termination and Tenant’s vacation and surrender of the Premises; or (iii) to permit Tenant to Assign this Lease or sublet such space, subject, however, to prior written approval of the proposed assignee or sublessee by Landlord, such consent not to be unreasonably withheld so long as the use of the Premises by such proposed assignee or sublessee would be a Permitted Use, the proposed assignee or sublessee is of sound financial condition as determined by Landlord in its reasonable discretion, the proposed assignee or sublessee executes such reasonable assumption documentation as Landlord shall require, and the proposed assignee or sublessee is not a party with whom with whom Landlord has negotiated regarding a prospective lease in the preceding ninety (90) days (which

21

negotiations have included, at a minimum, submittal of a written conditional offer or a letter of intent and counter offer or counter letter of intent).  If Landlord fails to notify Tenant in writing of such election within such period, Landlord shall be deemed to have waived option (ii) above, but written approval by Landlord of the proposed assignee or sublessee shall still be required.  Failure by Landlord to approve a proposed subtenant or assignee shall not cause a termination of this Lease.

7.4          Assignment/Subletting Fee.  In the event Tenant shall request the consent of Landlord to any assignment or subletting hereunder, Tenant shall pay Landlord a processing fee of $750.00 at the time of such request and shall reimburse Landlord for Landlord’s reasonable attorneys’ fees incurred in connection therewith.   All such fees shall be deemed Additional Rent under this Lease.

7.5          Assignment/Sublease Profit.  In the event that Tenant Assigns this Lease, Tenant shall pay to Landlord as additional rent an amount equal to fifty percent (50%) of any Increased Rent (as defined below) when and as such Increased Rent is received by Tenant, provided Tenant shall first be entitled to subtract Transfer Costs from such Increased Rent.  As used in this Section, “Increased Rent” shall mean the excess of (i) all Rent and other consideration which Tenant is entitled to receive by reason of any sale, sublease, assignment or other transfer of this Lease over (ii) the Rent otherwise payable by Tenant under this Lease at such time.  “Transfer Costs” means (a) any brokerage commissions paid by Tenant in connection with the subletting or assignment (not to exceed commissions typically paid in the market at the time of such subletting or assignment), (b) reasonable legal fees paid by Tenant in connection with such assignment or subletting (provided that Tenant shall submit to Landlord evidence reasonably acceptable to Landlord of such legal fees actually paid by Tenant, which evidence shall include copies of the applicable attorney bills), (c) any improvement allowance or construction costs incurred by Tenant in connection with the assignment or sublease, and (d) any other concession (including, without limitation, free rent) provided by Tenant which is they typically provided in the market, provided that, as a condition to Tenant recapturing the assignment or subletting costs, Tenant shall provide to Landlord, within ninety (90) days of Landlord’s execution of Landlord’s consent to the assignment or subletting, a detailed accounting of the assignment or subletting costs and supporting documents, such as receipts and construction invoices.  For purposes of the foregoing, any consideration received by Tenant in form other than cash shall be valued at its fair market value as determined by Landlord in good faith.

7.6          No Waiver.  The consent of Landlord to any assignment or subletting shall not constitute a consent to any subsequent assignment or subletting by Tenant or to any subsequent or successive assignment or subletting by the assignee or subtenant.  However, Landlord may consent to subsequent assignments and sublettings of the Lease or to subleases or amendments or modifications thereto, without notifying Tenant or any other party liable on the Lease or the sublease and without obtaining their consent.  Such action shall not relieve Tenant or any such other party from liability under this Lease or under any such sublease.

7.7          Tenant Remains Liable.  No assignment or subletting by Tenant shall relieve Tenant of any obligation under this Lease.  In the event of default by an assignee or subtenant of Tenant or any successor of Tenant in the performance of any of the terms hereof, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against such assignee, subtenant or successor.  Any assignment or subletting which conflicts with the provisions hereof shall be void and, at Landlord’s option, shall constitute an event of default under this Lease.

7.8          Short Term Sublease Exception to Landlord Recapture and Profit Sharing Rights.  Notwithstanding anything to the contrary in this Article 7, Tenant may from time to time enter into one or more Qualifying Subleases of a portion of the Premises and Landlord’s recapture right pursuant to item (ii) of the first sentence of Section 7.3 above and Landlord’s profit sharing rights under Section 7.5 above shall not apply to any such Qualifying Sublease.  A sublease is a “Qualifying Sublease” so long as (i) no more than twenty percent (20%) of the rentable square footage of the Premises is so used at any one time, (ii) the use of the space is not a use which materially increases (a) the operating costs for the Building, (b) the burden on the Building services, or (c) the foot traffic, elevator usage or security concerns in the Building, (iii) the use of such space is a permitted use under this Lease, and (iv) the term of such sublease (including any extensions or renewals) does not exceed twenty four (24) months.  The rights set forth in this Section 7.8 are personal to the Tenant originally named under this Lease and its Affiliate Transferees (as defined below), and shall not inure to the benefit of any other successor, assignee or subtenant of Tenant.  Tenant shall pay the cost of any demising (if any) which is required in connection with a

22

Qualifying Sublease, and at Landlord’s election shall remove such required demising walls at the expiration or termination of the Qualifying Sublease.  Except as specifically provided in this Section 7.8, the provisions of this Article 7 shall apply to Qualifying Subleases.

7.9          Affiliate Transferees. Notwithstanding anything to the contrary in this Article 7, but subject to Sections 7.4, 7.6 and 7.7. (but not subject to Sections 7.3 and 7.5), Tenant may assign this Lease or sublet the Premises or any portion thereof, without Landlord’s consent, to any partnership, corporation or other entity which controls, is controlled by, or is under common control with Tenant or Tenant’s parent (control being defined for such purposes as ownership of at least 50% of the equity interests in, or the power to direct the management of, the relevant entity) or to any partnership, corporation or other entity resulting from a merger or consolidation with Tenant or Tenant’s parent, or to any person or entity which acquires substantially all the assets of Tenant as a going concern (collectively, an “Affiliate”), provided that (i) Landlord receives prior written notice of an assignment or subletting, if possible, and if not possible then Landlord received notice of the assignment or subletting as soon as reasonably practicable after the date thereof, (ii) the Affiliate’s net worth is not less than Tenant’s net worth immediately prior to the assignment or subletting, (iii) the proposed transfer is not entered into as a subterfuge to evade the obligations and restrictions relating to transfers set forth in this Article 7, (iv) the Affiliate assumes (in the event of an assignment) in writing all of Tenant’s obligations under this Lease, (v) Landlord receives a fully executed copy of an assignment or sublease agreement between Tenant and the Affiliate, and (vi) there has been delivered to Landlord a fully executed counterpart of Landlord’s consent to sublease form or, in the case of an assignment to an Affiliate, a form in which the Affiliate acknowledges that occupancy of the Premises by Affiliate is subject to this Lease in which the Affiliate provides waivers and releases to the same extent as provided by Tenant under this Lease.  If Tenant does not promptly provide Landlord with all instruments and information required hereunder which are reasonably required to document that the proposed assignment or sublease is a transfer to an Affiliate not requiring Landlord’s consent hereunder, then Landlord may, at Landlord’s election made by written notice to Tenant, treat the transfer or notice of the assignment or sublease as a notice of intent to assign or sublet to a non-Affiliate, and all of Landlord’s rights hereunder with respect to a proposed assignment or sublease to a non-Affiliate shall thereupon apply as if such request had been made on the date of Landlord’s election.  An Affiliate subtenant or assignee meeting the requirements of this Section 7.9 is referred to as an “Affiliate Transferee.”

ARTICLE 8.
ALTERATIONS, ADDITIONS AND IMPROVEMENTS

8.1          Landlord Consent.  Tenant shall not make or allow to be made any alterations or additions in or to the Premises without first obtaining the written consent of Landlord.  Landlord’s consent will not be unreasonably withheld or delayed with respect to proposed alterations and additions which: (i) comply with all applicable laws, ordinances, rules and regulations; (ii) are compatible with the Building and its mechanical, electrical, HVAC and life safety systems; (iii) will not affect the structural portions of the Building (provided, however, Landlord shall not unreasonably withhold consent to the construction of an internal staircase in accordance with and subject to the terms and conditions of the Work Letter); (iv) will not interfere with the use and occupancy of any other portion of the Building by any other tenant; and (v) will not trigger any additional costs to Landlord.  Specifically, but without limiting the generality of the foregoing, Landlord’s right of consent (which shall not be unreasonably withheld) shall encompass plans and specifications for proposed alterations or additions, construction means and methods, the identity of any contractor or subcontractor to be employed on the work of alterations or additions, and the time for performance of such work.  Tenant shall supply to Landlord any additional documents and information requested by Landlord in connection with Tenant’s request for consent hereunder.  Notwithstanding the foregoing or anything to the contrary contained elsewhere in this Article 8, Tenant shall have the right, without Landlord’s consent, to make any alteration that meets all of the following criteria (a “Cosmetic Alteration”): (a) the alteration is decorative in nature (such as paint, carpet or other wall or floor finishes, movable partitions or other such work) or is limited to Tenant’s data and communications cabling, (b) Tenant provides Landlord with ten (10)  days’ advance written notice of the commencement of such alteration, (c) such alteration does not affect the Building’s electrical, mechanical, life safety, plumbing, security, or HVAC systems or any other portion of the base building or any part of the Building other than the Premises, (d) the work will not decrease the value of the Premises, uses only new or like-new materials comparable in quality to those being replaced and is performed in a workman like manner and in accordance with all legal requirements, and (e) the cost of such alteration does not exceed Ten Thousand Dollars ($10,000.00) per project.  At the time Tenant notifies Landlord of any Cosmetic Alteration, Tenant shall give Landlord a copy of Tenant’s plans for the work.  If the Cosmetic Alteration is of such a nature that formal plans will

23

not be prepared for the work, Tenant shall provide Landlord with a reasonably specific written description of the work.

8.2          Permits and Plans.  Any consent given by Landlord under this Section 8.2 shall be deemed conditioned upon: (i) Tenant’s acquiring all applicable permits required by governmental authorities; (ii) Tenant’s furnishing to Landlord copies of such permits, together with copies of the approved plans and specifications, prior to commencement of the work thereon; and (iii) compliance by Tenant with the conditions of all applicable permits and approvals in a prompt and expeditious manner.

8.3          Freedom From Liens.  Tenant shall provide Landlord with not less than ten (10) days prior written notice of commencement of the work so as to enable Landlord to post and record appropriate notices of non-responsibility.  All alterations and additions permitted hereunder shall be made and performed by Tenant without cost or expense to Landlord.  Tenant shall pay the contractors and suppliers all amounts due to them when due and keep the Premises and the Project free from any and all mechanics’, materialmen’s and other liens and claims arising out of any work performed, materials furnished or obligations incurred by or for Tenant.  Prior to the commencement of any alterations and additions permitted hereunder, Landlord may require, at its sole option, that Tenant provide Landlord with satisfactory evidence of Tenant’s ability to pay for the work.

8.4          Alterations Upon Lease Expiration.  Any and all alterations, additions or improvements made to the Premises by Tenant shall be the property of Tenant during the Lease term, and shall become the property of Landlord upon the expiration or earlier termination of this Lease, and shall be surrendered to Landlord without compensation to Tenant upon the termination of this Lease by lapse of time or otherwise unless Landlord conditioned its approval of such alterations, additions or improvements on Tenant’s agreement to remove them (provided that Landlord shall only require the removal of Tenant Cables and Extraordinary Fixtures, as defined below).  Notwithstanding the foregoing, on or prior to the expiration of this Lease, Tenant shall remove from the Premises and the Common Areas all telephone, data or video cables installed by or on behalf of Tenant (the “Tenant Cables”), except those telephone, data or video cables which Landlord specifically agrees may remain in a written notice to Tenant prior to the expiration of the Term.  Tenant shall, by the Expiration Date (or promptly thereafter), remove such alterations, additions and improvements which Tenant is required to remove hereunder, repair any damage resulting from such removal (including any penetrations required for the initial installation of such items), and restore the Premises to their condition existing prior to the date of installation of such alterations, additions and improvements.  Notwithstanding anything to the contrary set forth above, this clause shall not apply to modular walls, movable equipment or furniture owned by Tenant.  Further, Tenant shall repair at its sole cost and expense all damage caused to the Premises and the Project by removal of Tenant’s modular walls, movable equipment or furniture and such other alterations, additions and improvements as Tenant shall be required or allowed by Landlord to remove from the Premises.  As used herein, the term “Extraordinary Fixture” means an alteration, addition or improvement which, at the time of installation, is not the type quality, or quantity of improvement that is customarily found in a standard office installation in first class office building in the South of Market Street area of San Francisco, California.  By way of example only, rolling or built-in high density file systems, vaults, safes, raised flooring, dedicated tenant elevators or dumb waiters, special key card systems on stairwells or other entry doors, and internal stairways constitute Extraordinary Fixtures.

8.5          Construction of Alterations.  All alterations, additions and improvements permitted under this Section 8.5 shall be constructed diligently, in a good and workmanlike manner with new or like-new, good and sufficient materials and in compliance with all applicable laws, ordinances, rules and regulations (including, without limitation, building codes and those related to accessibility and use by individuals with disabilities) and in accordance with Landlord’s construction rules attached hereto as Exhibit E.  Installation by or on behalf of Tenant, prior to the Commencement Date or during the Term of this Lease, of conduits, electrical wires, and telephone, data or video cables in the vertical shafts, horizontal raceways, electrical closets and telephone closets of the Building or other Common Areas of the Building designed for the installation of such conduits, electrical wires and cables shall be subject to such regulations and conditions as Landlord may from time to time reasonably impose.  Tenant shall, promptly upon completion of the work, furnish Landlord with “as built” drawings for any alterations, additions or improvements performed under this Section 8.5.  If any alterations, additions or improvements which Tenant causes to be constructed in the Premises result in Landlord being required to make any alterations and/or improvements to other portions of the Project in order to comply with any applicable laws, ordinances or regulations, then Tenant shall reimburse Landlord upon demand for all costs and expenses incurred by Landlord in making such alterations

and/or improvements (provided that Tenant shall not be required to reimburse Landlord for the costs of Excused Work, as defined in Section 6.6).  Except to the extent otherwise specifically agreed by Landlord in writing, in the event any alterations or additions to the Premises are performed by Landlord hereunder, Landlord shall be entitled to charge Tenant a seven percent (7%) administration fee in addition to the actual costs of labor and materials provided.  Such costs and fees shall be deemed Additional Rent under this Lease, and may be charged and payable prior to commencement of the work.

ARTICLE 9.
SUBORDINATION, NONDISTURBANCE AND ATTORNMENT

9.1          Subordination.  This Lease and the rights of Tenant hereunder shall be subject and subordinate to the lien of any deed of trust, mortgage or other security instrument (collectively, a “Security Device”) now or hereafter placed upon, affecting or encumbering the Project or any part thereof or interest therein, and to any and all advances made thereunder, interest thereon or costs incurred and any modifications, renewals, supplements, consolidations, replacements and extensions thereof.  With respect to any Security Device entered into by Landlord after the date of execution of this Lease, Tenant’s obligation to subordinate the rights of Tenant hereunder to such Security Device shall be conditioned on Tenant’s receipt from the holder of or beneficiary under such encumbrance (each, a “Holder”) of assurance (a “nondisturbance agreement”), in commercially reasonable form, that Tenant’s possession and rights under this Lease will not be disturbed so long as Tenant is not in default under this Lease and attorns to the record owner of the Premises.  Without the consent of Tenant, a Holder shall have the right to elect to be subject and subordinate to this Lease, such subordination to be effective upon such terms and conditions as such Holder may direct which are not inconsistent with the provisions hereof.  Tenant agrees to attorn to, and recognize as the Landlord under this Lease, the Holder or any other party that acquires ownership of the Premises by reason of a foreclosure or sale under any Security Device (or deed in lieu thereof) and to execute such agreements confirming such attornment as such party may reasonably request subject to Tenant’s receipt of a nondisturbance agreement, as required hereunder.  The new owner following a foreclosure or a sale or deed in lieu of foreclosure under a Security Device shall not be (i) liable for any act or omission of any prior landlord or with respect to events occurring prior to acquisition of ownership (but shall cure any default of a prior landlord that is continuing as of the date the new owner acquires legal title to the Project); (ii) subject to any offsets or defenses which Tenant might have against any prior landlord (except to the extent that (A) such offset or defense is specifically provided by this Lease, (B) the new owner has been notified in writing of the situation giving rise to such offset or defense, and (C) the new owner has failed to remedy such situation within the same period of time as is given the landlord under the Lease (but not less than thirty (30) days) to remedy such situation); (iii) bound by prepayment of more than one (1) month’s Rent; or (iv) liable to Tenant for any security deposit not actually received by such new owner.  Landlord warrants that as of the date hereof there is no Security Device encumbering the Project.

9.2          Lease Modifications.  Tenant shall not unreasonably withhold its consent to changes or amendments to this Lease requested by a Holder so long as these changes do not alter the basic business terms of this Lease or otherwise materially diminish any rights or materially increase any obligations of Tenant hereunder. Tenant’s failure to deliver the required document within ten (10) days of Landlord’s written request therefor shall constitute an Event of Default if the same is not thereafter delivered within five (5) days of notice of such failure.

9.3          Landlord Mortgagee Cure Rights.  Tenant shall promptly notify each Holder (of whom Tenant has received written notice) of any default by Landlord under this Lease which would entitle Tenant to cancel or terminate this Lease, and agrees that, notwithstanding any provisions of this Lease to the contrary, no notice of cancellation or termination as a result of such default shall be effective unless the Holder shall have received notice of the default giving rise to such cancellation or termination and such Holder shall have failed to cure such default (i) within the cure period available to Landlord under this Lease or (ii) within thirty (30) days following the date on which possession of the Project is obtained by such Holder, if such act or omission is not capable of being remedied without possession of the Project; provided, however, that if such default is not capable of cure within the relevant thirty (30)-day period, then, provided that such Holder has commenced such cure within the relevant thirty (30)-day period then such period shall be extended so long as such Holder is thereafter diligently pursuing any action necessary to cure such default.

10.3        Limitations on Assignment and Subletting.  It shall not be unreasonable for Landlord to withhold its consent to any proposed assignment or subletting of the Premises if the proposed transferee’s anticipated use of the Premises involves the generation, storage, use, treatment, or disposal of Hazardous Material (excluding standard office and janitorial supplies in limited quantities as hereinabove provided).

10.4        Right of Entry.  Landlord, its employees, agents and consultants, shall have the right to enter the Premises at any time, in case of an emergency, and otherwise during reasonable hours and upon at least five (5) business days written notice to Tenant, in order to conduct periodic environmental inspections and tests to determine whether any Hazardous Materials are present.  The costs and expenses of such inspections shall be paid by Landlord unless a default or breach by Tenant of this Article 10 or contamination caused or permitted by Tenant is found to exist.  In such event, Tenant shall reimburse Landlord upon demand, as Additional Rent, for the costs and expenses of such inspections.

26

ARTICLE 11.
INSURANCE, INDEMNITY

11.1        Tenant’s Liability Insurance.  Tenant (with respect to both the Premises and the Project) shall secure and maintain, at its own expense, at all times during the Term, a policy or policies of commercial general liability insurance with the premiums thereon fully paid in advance, protecting Tenant and naming Landlord, any Holders or ground lessors on the Project, and Landlord’s representatives (which term, whenever used in this Article 11, shall be deemed to include Landlord’s asset manager, Bay West Group, Bay West Showplace Investors LLC, Landlord’s partners, any subsidiary or affiliate of Landlord and the officers, directors, shareholders, partners, employees, managers, independent contractors and agents of any of the foregoing) as additional insureds against claims for bodily injury, personal injury and property damage (including attorneys’ fees) based upon, involving or arising directly or indirectly out of Tenant’s or its agents, employees, contractors, subcontractors, invitees, subtenants or licensees’ operations, assumed liabilities or Tenant’s use, occupancy or maintenance of the Premises and the Project.  Such insurance shall provide for a minimum amount of Three Million Dollars ($3,000,000.00) for property damage or injury to or death of one or more than one person in any one accident or occurrence, with an annual aggregate limit of at least Five Million Dollars ($5,000,000.00), which insurance may be provided in a combination of primary and excess limits.  The coverage required to be carried shall include fire legal liability, blanket contractual liability, personal injury liability, broad form property damage liability, products liability and completed operations coverage (as well as owned, non-owned and hired automobile liability if an exposure exists) and the policy shall contain an exception to any pollution exclusion should bodily injury or property damage arise out of heat, smoke or fumes from a hostile fire.  The foregoing policies carried by Tenant shall be primary to any other insurance maintained by Landlord.  Such insurance shall be written on an occurrence basis and contain a separation of insureds provision or cross-liability endorsement acceptable to Landlord.  Tenant shall provide Landlord with a certificate evidencing such insurance coverage prior to the Commencement Date.  Not more frequently than every two (2) years during the Extension Period or during any other extension of the term of this Lease, if, in the opinion of any Holder (as defined in Section 9.1) or of the insurance broker retained by Landlord, the amount of liability insurance coverage at that time is not adequate, then Tenant shall increase its liability insurance coverage as required by either any mortgagee of Landlord or Landlord’s insurance broker, provided such increased amount shall not materially exceed the greater of (a) those amounts normally required for comparable buildings in the geographic area of the Project or (b) those amounts required to provide Landlord with the same relative protection as the amounts set forth above as of the date of this Lease.  Tenant shall, at Tenant’s expense, comply with (i) all insurance company requirements pertaining to the use of the Premises and (ii) all rules, orders,

27

regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and any similar body.

11.2        Tenant’s Additional Insurance Requirements.

(a)           Tenant shall secure and maintain, at Tenant’s expense, at all times during the Term, a policy of physical damage insurance on all of Tenant’s fixtures, furnishings, equipment, machinery, merchandise and personal property in the Premises and on any alterations, additions or improvements made by or for Tenant upon the Premises, all for the full replacement cost thereof without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance.  Such insurance shall insure against those risks customarily covered in a policy of property insurance in so called “Special Form” or “Special Perils” form covering physical loss or damage.  Tenant shall use the proceeds from such insurance for the restoration of the alterations, additions or improvements made by or for Tenant to the Premises, including, without limitation, the Tenant Improvements.  In addition, Tenant shall secure and maintain, at all times during the Term, business interruption and extra expense insurance in such amounts as will substantially support the payment of annual rent under this Lease (not to exceed $2,500,000.00), to the extent an interruption is attributable to any perils commonly insured against by prudent tenants or attributable to prevention of access to the Premises or to the Building as a result of such perils; such insurance shall be maintained with Tenant’s property insurance carrier.  Further, Tenant shall secure and maintain at all times during the Term workers’ compensation insurance in such amounts as are required by law, employer’s liability insurance in the amount of not less than One Million Dollars ($1,000,000.00) per occurrence, and all such other insurance as may be required by applicable law. Tenant shall provide Landlord with certificates of all such insurance prior to the Commencement Date.  The property insurance certificate shall confirm that the waiver of subrogation required to be obtained pursuant to Section 11.5 is permitted by the insurer.  Tenant shall, at least thirty (30) days prior to the expiration of any policy of insurance required to be maintained by Tenant under this Lease, furnish Landlord with an “insurance binder” or other satisfactory evidence of renewal thereof.

(b)           In the event Tenant makes any alterations, additions or improvements to the Premises, prior to commencing any work in the Premises, Tenant shall secure “builder’s all risk” insurance which shall be maintained throughout the course of construction.  Such policy shall be an all risk builder’s risk completed value form, in an amount reasonably approved by Landlord, in all events not less than the total contract price for the construction of such alterations, additions or improvements and covering the construction of such alterations, additions or improvements, and such other insurance as Landlord may require, it being understood and agreed that all of such alterations, additions or improvements shall be insured by Tenant pursuant to Section 11.2(a) immediately upon completion thereof.  Tenant shall promptly provide Landlord with a certificate evidencing such insurance coverage.

(c)           All policies required to be carried by Tenant under this Lease shall be issued by and binding upon a reputable insurance company of good financial standing licensed to do business in the State of California with a rating of at least A:VII, or such other rating as may be required by any Holder, as set forth in the most current issue of “Best’s Insurance Reports.”  Tenant shall not do or permit anything to be done that would invalidate the insurance policies referred to in this Article 11.  Evidence of insurance provided to Landlord shall include an endorsement showing that Landlord, its representatives and any Holders or ground lessors on the Project, are included as additional insureds with respect to the commercial general liability insurance and a loss payee with respect to the property coverage with respect to Landlord’s interest therein, and an endorsement whereby the insurer agrees to endeavor to provide at least ten (10) days prior written notice of cancellation to Landlord and any mortgagee of Landlord named as an additional insured or loss payee.

(d)           In the event that Tenant fails to provide evidence of insurance required to be provided by Tenant under this Lease, prior to commencement of the Term, and thereafter during the Term, within ten (10) days following Landlord’s request therefor, and ten (10) days prior to the expiration date of any such coverage, Landlord shall be authorized (but not required) to procure such coverage in the amounts stated with all costs thereof (plus a ten percent (10%) administrative fee) to be chargeable to Tenant and payable upon written invoice therefor, which amounts shall be deemed Additional Rent hereunder.

28

(e)           The minimum limits of insurance required by this Lease, or as carried by Tenant, shall not limit the liability of Tenant nor relieve Tenant of any obligation hereunder.

11.3        Landlord Insurance.  During the Term of this Lease Landlord shall maintain property insurance in so called “Special Form” or “Special Perils” form covering the Project (but excluding the Tenant Improvements and alterations made by or for Tenant) for the full replacement cost thereof, excluding footings, foundations and below-grade improvements, with a deductible provision, if any, that does not materially exceed that which prudent, efficient operators of first class low rise office buildings in the downtown San Francisco would carry from time to time in the exercise of reasonable business judgment.

11.4        Indemnity and Exoneration.

(a)           Landlord and Landlord’s agents and employees shall not be liable to Tenant, nor to Tenant’s employees, agents, contractors, subcontractors, invitees, subtenants or licensees (each, a “Tenant Party”), nor to any other person whomsoever, for any injury to person or damage to property caused by: (a) the Premises or other portions of the Project becoming out of repair, (b) any defect or failure of any structural element of the Premises or of any equipment, pipes or wiring, or broken glass; (c) the backing up of drains, (d) gas, water, steam, electricity, or oil leaking, escaping or flowing into the Premises; or (e) the acts or omissions of other tenants of the Building or of any other persons whomsoever, excepting only loss or damage to the extent caused by the gross negligence or willful misconduct of Landlord or its agents or contractors. Further, Landlord shall not be liable to Tenant, any Tenant Party, or to any other person whomsoever, for any injury to person or damage to property on or about the Premises or the Common Area caused by: (i) the negligence or misconduct of Tenant, any Tenant Party, or any other person entering the Building under express or implied invitation of Tenant (with the exception of invitees in the Common Area), (ii) arising out of the use of the Premises and the conduct of its business therein or parking spaces leased hereunder by Tenant, or (iii) arising out of any breach or default by Tenant in the performance of its obligations under this Lease.  Under no circumstances will Landlord ever be liable to Tenant for consequential damages or lost profits.  Landlord shall not be held responsible in any way on account of any construction, repair or reconstruction (including widening) of any private or public roadways, walkways or utility lines.  Tenant’s assumption of risk of damage under this Section 11.3(a) is a material part of the consideration to Landlord for this Lease.

(b)           Except to the extent caused by the negligence of willful misconduct of Landlord or its agents or contractors, Tenant shall indemnify, defend and hold harmless Landlord, Landlord’s asset manager, Bay West Group, Bay West Showplace Investors LLC, Landlord’s partners, any subsidiary or affiliate of Landlord and the officers, directors, shareholders, partners, employees, managers, independent contractors, attorneys and agents of any of the foregoing (collectively, the “Indemnitees”) from and against any and all claims, demands, causes of action, judgments, costs and expenses, and all losses and damages (including consequential and punitive damages) arising from: (i) Tenant’s use or occupancy of the Premises and the parking spaces leased hereunder; (ii) the conduct of its business or from any activity, work, or other acts or things done, permitted or suffered by Tenant in or about the Premises or the Project; (iii) any breach or default in the performance of any obligation on Tenant’s part to be performed under the terms of this Lease; (iv) arising from any act, omission or negligence or willful or criminal misconduct of Tenant or any Tenant Party; and (v) all costs, attorneys’ fees and disbursements, and liabilities incurred in the defense of any such claim or any action or proceeding which may be brought against, out of or in any way related to this Lease. Upon notice from Landlord, Tenant shall defend any such claim, demand, cause of action or suit at Tenant’s expense by counsel reasonably satisfactory to Landlord.  Except to the extent caused by the negligence or willful misconduct of Tenant or its agents or contractors or a breach of Tenant’s obligations under the Lease, Landlord shall indemnify, defend and hold harmless Tenant and the officers, directors, shareholders, partners, employees, managers, independent contractors, attorneys and agents of Tenant from and against any and all claims, demands, causes of action, judgments, costs and expenses, and all losses and damages (including punitive damages) (i) to the extent arising from arising from any negligence or willful or criminal misconduct of Landlord or its agents or contractors; and (ii) all costs, attorneys’ fees and disbursements, and liabilities incurred in the defense of any such claim. Upon notice from Tenant, Landlord shall defend any such claim, demand, cause of action or suit at Landlord’s expense by counsel reasonably satisfactory to Tenant.  Notwithstanding anything to the contrary set forth in this Section 11.4, in no event shall Landlord be liable for any consequential damages, or for loss of or damage to artwork, currency, jewelry, bullion, securities or other property in the Premises, not in the nature of ordinary fixtures, furnishings, equipment and other property used in general business office activities and functions.

29

(c)           Tenant shall indemnify, protect, defend and hold Landlord and its representatives, harmless of and from any and all claims, liability, costs, penalties, fines, damages, injury, judgments, forfeiture, losses or expenses (including without limitation attorneys’ fees, consultant fees, testing and investigation fees, expert fees and court costs) arising out of or in any way related to or resulting directly or indirectly from work or labor performed, materials or supplies furnished to or at the request of Tenant or in connection with obligations incurred by or performance of any work done for the account of Tenant in the Premises or the Project.

(d)           The provisions of this Section 11.3 shall survive the expiration or sooner termination of this Lease.

11.5        Waiver of Subrogation.  Notwithstanding anything to the contrary in this Lease, Landlord and Tenant each hereby waive all rights of recovery against the other on account of loss and damage occasioned to such waiving party for its property or the property of others under its control to the extent that such loss or damage is required to be or is actually insured against hereunder.  Tenant and Landlord shall, upon obtaining policies of insurance required hereunder, give notice to the insurance carrier that the foregoing mutual waiver of subrogation is contained in this Lease and Tenant and Landlord shall cause each insurance policy obtained by such party to provide that the insurance company waives all right of recovery by way of subrogation against either Landlord or Tenant in connection with any damage covered by such policy.

ARTICLE 12.
CONDEMNATION

12.1        Condemnation.  If the Premises or any portion thereof are taken under the power of eminent domain or sold under the threat of the exercise of such power (all of which are referred to herein as “condemnation”), this Lease shall terminate as to the part so taken as of the date the condemning authority takes title or possession, whichever first occurs (the “date of taking”).  If the Premises or any portion of the Project is taken by condemnation to such an extent as to render the Premises or more than fifteen percent (15%) thereof untenantable or uneconomical for Tenant’s business, this Lease shall, at the option of either party to be exercised in writing within thirty (30) days after receipt of written notice of such taking, forthwith cease and terminate as of the date of taking.  All proceeds from any condemnation of the Premises shall belong to and be paid to Landlord, subject to the rights of any holder of any Security Device(s) on the Project; provided that Tenant shall be entitled to any compensation separately awarded to Tenant for Tenant’s relocation expenses or loss of Tenant’s trade fixtures and the unamortized cost of alterations and improvements paid for by Tenant (including, without limitation, a share of the cost of the Tenant Improvements).  If this Lease continues in effect after the date of taking pursuant to the provisions of this Section 12.1, Landlord shall proceed with reasonable diligence to repair, at its expense, the remaining parts of the Project and the Premises (other than that portion of the Tenant Improvements paid for by Tenant) to substantially their former condition to the extent that the same is feasible (subject to reasonable changes which Landlord shall deem desirable) and so as to constitute a complete and tenantable Project and Premises.  Rent shall abate to the extent appropriate during the period of restoration, and Rent shall thereafter be equitably adjusted according to the remaining Rentable Area of the Premises and the Building.  The rights contained in this Article 18 shall be Tenant’s sole and exclusive remedy in the event of a taking or condemnation. Each party waives the provisions of Sections 1265.130 and 1265.150 of the California Code of Civil Procedure and the provisions of any successor or other law of like import.

12.2        Landlord Termination Rights.  Notwithstanding anything to the contrary, Landlord may terminate this Lease with no further liability to Tenant if (i) fifty percent (50%) or more of the gross leasable area of the Project is taken or (ii) if following any material taking, the Holder elects to require Landlord to apply all or a material portion of such award to the outstanding indebtedness.

ARTICLE 13.
DAMAGE OR DESTRUCTION

13.1        Premises Damaged; Landlord Repair Obligations.  In the event of a fire or other casualty in the Premises, Tenant shall immediately give notice thereof to Landlord and the provisions of this Article 13 shall apply.  If the damage is limited solely to the Premises, Landlord shall promptly give Tenant notice of Landlord’s reasonable estimate of the time required to make the required repairs (the “Premises Repair Estimate”). If the Lease is not

30

terminated by Landlord or Tenant pursuant to this Article 13, then Landlord shall be obligated to rebuild the same to substantially their former condition to the extent that the same is feasible (subject to reasonable changes which Landlord shall deem desirable (provided such changes do not have a material adverse impact on Tenant’s use or enjoyment of the Premises) and such changes as may be required by applicable law) and shall proceed with reasonable diligence to do so and this Lease shall remain in full force and effect.  Notwithstanding anything to the contrary in this Article 13, Landlord shall not be required to repair or replace any of Tenant’s furniture, fixtures, equipment, or any other improvements to the Premises, including, without limitation, the Tenant Improvements.

13.2        Project Damaged; Landlord Repair Obligations.  If portions of the Project outside the boundaries of the Premises are damaged or destroyed (whether or not the Premises are also damaged or destroyed), Landlord shall promptly give Tenant notice of Landlord’s reasonable estimate of the time required to make required repairs (the “Project Repair Estimate”). If the Lease is not terminated by Landlord or Tenant pursuant to this Article 13, then Landlord shall be obligated to rebuild the same to substantially their former condition to the extent that the same is feasible (subject to reasonable changes which Landlord shall deem desirable (provided such changes do not have a material adverse impact on Tenant’s use or enjoyment of the Premises) and such changes as may be required by applicable law) and shall proceed with reasonable diligence to do so and this Lease shall remain in full force and effect.

13.3        Damage During Last Twelve Months of Term.  Notwithstanding anything to the contrary contained in Sections 13.1 or 13.2 above, Landlord shall not have any obligation whatsoever to repair, reconstruct or restore the Premises or the Project when the completion of the repair damage thereto or to the Project would occur during the last six (6) months of the Term and Tenant has not effectively exercised any option granted to Tenant to extend the Term.  Under such circumstances, Landlord shall promptly notify Tenant of its decision not to rebuild, whereupon the Lease shall terminate as of the date of such notice.

13.4        Extensive Damage; Uninsured Damage; Rights of Landlord and Tenant to Terminate.

(a)           If the Premises Repair Estimate indicates that the damage to the Premises cannot be repaired within twelve (12) months of the date of damage, Tenant may terminate this Lease within thirty (30) days after the date of such the Premises Repair Estimate, such termination notice to be immediately effective. If the Project Repair Estimate indicates that the damage to the Project cannot be repaired within twelve (12) months of the date of damage, and that portion of the Project damaged is required for Tenant’s use and enjoyment of the Premises, Tenant may terminate this Lease within thirty (30) days after the date of such the Premises Repair Estimate, such termination notice to be immediately effective.  If the Premises Repair Estimate or the Project Repair Estimate indicates that the damage to the Premises or the Project cannot be repaired within twelve (12) months of the date of damage, Landlord may terminate this Lease within thirty (30) days after the date of such the Premises Repair Estimate or Project Repair Estimate, as applicable, such termination notice to be immediately effective, provided that Landlord shall not terminate this Lease unless (i) Landlord is also terminating the leases of all similarly affected tenants, and (ii) either (A) more than twenty-five percent (25%) of the total leaseable area of the Building is damaged or destroyed, or (B) structural portions of the Premises or of the Building are damaged, the estimated cost of repair which exceeds twenty percent (20%) of the then estimated replacement cost of the Building.

(b)           Further, notwithstanding anything to the contrary in this Article 13 but subject to the following provisions of this Section 13.4(b), Landlord shall have no obligation to repair or restore the Premises or the Project except to the extent that insurance proceeds are made available to Landlord sufficient for such purpose and for all other restoration and repair purposes (taking into account the deductible portion of such loss for which Landlord will be reimbursed by Tenant or other tenants of the Building as an Operating Cost) (or sufficient proceeds would have been made available to Landlord had Landlord carried the insurance which Landlord is required to carry pursuant to the terms of this Lease, in which event for the purposes of this Section 13.1(b) such proceeds shall be deemed to have been made available to Landlord).  If sufficient insurance proceeds are not made available to Landlord (or deemed to have been made available) (taking into account the deductible portion of such loss for which Landlord will be reimbursed by Tenant or other tenants of the Building as an Operating Cost) to repair damage to the Premises or the Project, then the uninsured cost to repair and restore the portions of the Premises and Project for which Landlord is responsible, as reasonably estimated by Landlord’s architect, shall be referred to herein as the “Shortfall”.  If the Shortfall with respect to the Premises and the common areas of the Project necessary for Tenant’s use and enjoyment of the Premises is greater than Two Hundred Fifty Thousand Dollars ($250,000.00) (the

“Premises Shortfall Trigger”) or if the Shortfall with respect to the balance of the Project other than the Premises and the common areas of the Project necessary for Tenant’s use and enjoyment of the Premises is greater than five percent (5%) of the then replacement cost of the Building (the “Non-Premises Shortfall Trigger”), then in either such instance Landlord may elect by written notice to Tenant to terminate this Lease on account thereof, provided that Landlord is also terminating the leases of all similarly affected tenants, in which event Landlord shall provide Tenant with written notice of the estimated Shortfall and of Landlord’s election to terminate this Lease (the “Shortfall Termination Notice”).  If Landlord does not elect to terminate the Lease pursuant to the provisions of this Section 13.4(b), Landlord shall repair and restore the Premises and the common areas of the Project necessary for Tenant’s use and enjoyment of the Premises in accordance with the requirements of Sections 13.1 and 13.2 above.  If Landlord elects to terminate the Lease pursuant to the provisions of this Section 13.4(b), Tenant may at its sole discretion elect, by written notice to Landlord given within twenty (20) days of receipt of the Shortfall Termination Notice, to contribute the toward Landlord’s repair costs sufficient funds (“Tenant’s Contribution”) such that Tenant’ Contribution, together with the insurance proceeds made available to Landlord (if any), are sufficient to reduce Landlord’s uninsured repair cost below the Premises Shortfall Trigger and the Non-Premises Shortfall Trigger.  If Tenant so elects to make Tenant’s Contribution, Landlord shall thereupon repair and restore the Premises and the common areas of the Project necessary for Tenant’s use and enjoyment of the Premises in accordance with the requirements of Sections 13.1 and 13.2 above, Tenant shall pay Landlord Tenant’s Contribution, and this Lease shall continue in full force and effect.

13.5        Rent Abatement.  During any period when Tenant’s use of the Premises is significantly impaired by damage or destruction, Rent shall abate in proportion to the degree to which Tenant’s use of the Premises is impaired until such time as the Premises are made tenantable as reasonably determined by Landlord; provided that no such rental abatement shall be permitted if the casualty is a result of the negligence or willful misconduct of Tenant or Tenant’s employees, agents, contractors or invitees.

13.6        Insurance Proceeds.  The proceeds from any insurance paid by reason of damage to or destruction of the Project or any part thereof insured by Landlord shall belong to and be paid to Landlord, subject to the rights of any holder(s) of any Security Device(s) on the Project.  If this Lease is not terminated pursuant to the provisions of this Article 13, Tenant shall be responsible at its sole cost and expense for the repair, restoration and replacement of its alterations, additions, and improvements (including the Tenant’s Improvements); provided, however, that Landlord shall have the option of requiring Tenant to assign to Landlord (or any party designated by Landlord) some or all of the proceeds payable to Tenant under this Article 13, whereupon Landlord shall be responsible for the repair and restoration of such insured property.  Notwithstanding the foregoing to the contrary, if this Lease is terminated pursuant to the provisions of this Article 13, then that portion of Tenant’s insurance proceeds attributable to the Tenant Improvements shall be payable to Landlord and Tenant in the same proportion as Landlord’s and Tenant’s respective Share of Costs (as defined in the Work Letter), and that portion of Tenant’s insurance proceeds attributable to other improvements constructed by Landlord or funded in whole or in part by an improvement allowance from Landlord shall be payable to Landlord and Tenant in the same proportion as such party funded the cost of such improvement.  Tenant shall use reasonable efforts to collect the insurance proceeds to which it is entitled under the subject casualty insurance policy.

13.7        Waiver.  Landlord’s repair and restoration obligations under this Section 13.7 shall not impair or otherwise affect the rights and obligations of the parties set forth elsewhere in this Lease.  Subject to Section 13.5, Landlord shall not be liable for any inconvenience or annoyance to Tenant, its employees, agents, contractors or invitees, or injury to Tenant’s business resulting in any way from such damage or the repair thereof.  Landlord and Tenant agree that the terms of this Lease shall govern the effect of any damage to or destruction of the Premises or the Project with respect to the termination of this Lease and any statute or regulation of the State of California, including, without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to the Lease or any damage or destruction to all or any part of the Premises or the Project.

13.8        No Further Repair Obligations.  If this Lease is terminated pursuant to this Article 13, then provided that Tenant pays over to Landlord the insurance proceeds to which Landlord is entitled pursuant to Section 13.6 above, Tenant shall have no further obligations under this Lease to repair the Tenant Improvements.

ARTICLE 14.
DEFAULT BY TENANT

14.1        Events of Default.  The occurrence of any of the following shall constitute an “Event of Default” on the part of Tenant:

(a)           Tenant shall fail to pay any installment of Rent or any other obligation under this Lease involving the payment of money and such failure shall continue for a period of five (5) days after written notice to Tenant that such amount has become due and payable (any such notice shall be in lieu of, and not in addition to, any notice required under Section 1161 et seq. of the California Code of Civil Procedure) provided the same is served in the manner required under Section 1162 of the California Code of Civil Procedure;

(f)            The filing of any voluntary petition in bankruptcy by Tenant, or the filing of an involuntary petition against Tenant, which involuntary petition remains undischarged for a period of sixty (60) days.  In the event that under applicable law the trustee in bankruptcy or Tenant has the right to affirm this Lease and continue to perform the obligations of Tenant hereunder, such trustee or Tenant shall, within such time period as may be permitted by the bankruptcy court having jurisdiction, cure all defaults of Tenant hereunder outstanding as of the date of the affirmance of this Lease and provide to Landlord such adequate assurances as may be necessary to ensure Landlord of the continued performance of Tenant’s obligations under this Lease;

(g)           The appointment of a trustee or receiver to take possession of all or substantially all of Tenant’s assets or the Premises, where possession is not restored to Tenant within thirty (30) days;

(h)           The attachment, execution or other judicial seizure of all or substantially all of Tenant’s assets or the Premises, if such attachment or other seizure remains undismissed or undischarged for a period of thirty (30) days after the levy thereof;

(i)            The admission by Tenant in writing of its inability to pay its debts as they become due; the filing by Tenant of a petition seeking any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or future bankruptcy or similar statute, law or regulation; the filing by Tenant of an answer admitting or failing timely to contest a material allegation of a petition filed against Tenant in any such proceeding; or, if within sixty (60) days after the commencement of any proceeding against Tenant seeking any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or future statute, law or regulation, such proceeding shall not have been dismissed;

(j)            If the performance of Tenant’s obligations under this Lease is at any time during the Term guaranteed: (i) the death of a guarantor; (ii) the termination of a guarantor’s liability with respect to this Lease other than in accordance with the terms of such guaranty; (iii) a guarantor’s becoming insolvent or the subject of a bankruptcy filing; (iv) a guarantor’s refusal to honor the guaranty; or (v) a guarantor’s breach of its guaranty

33

obligation on an anticipatory breach basis, and Tenant’s failure, within thirty (30) days following written notice by or on behalf of Landlord to Tenant of any such event, to provide Landlord with written alternative assurance or security, which, when coupled with the then existing resources of Tenant, equals or exceeds the combined financial resources of Tenant and the guarantor(s) that existed at the time of execution of this Lease;

(k)           If Tenant under this Lease is at any time during the Term is a partnership or consists of more than one (1) person or entity, if any partner of the partnership or any person or entity constituting Tenant is involved in any of the events or acts described in Sections 14.1(d) through (h); or

(l)            The discovery by Landlord that any material representation, warranty or financial statement given to Landlord by Tenant under this Lease was materially and knowingly false when made.

14.2        Remedies Upon Default.  Upon an Event of Default, Landlord shall have the following remedies:

(a)           If an Event of Default occurs, Landlord shall have the right, with or without notice or demand, immediately (after expiration of any applicable grace period specified herein) to terminate this Lease, and at any time thereafter recover possession of the Premises or any part thereof (as well as the parking spaces leased by Tenant) and expel and remove therefrom Tenant and any other person occupying the same, by any lawful means, and again repossess and enjoy the Premises without prejudice to any of the remedies that Landlord may have under this Lease, or at law or in equity by reason of Tenant’s default or by reason of such termination.

(b)           Even though Tenant has breached this Lease and/or abandoned the Premises, this Lease shall continue in effect for so long as Landlord does not terminate Tenant’s right to possession under Section 14.2(a), and Landlord may enforce all of its rights and remedies under this Lease, including (but without limitation) the right to recover Rent as it becomes due, and Landlord, without terminating this Lease, may exercise all of the rights and remedies of a landlord under Section 1951.4 of the Civil Code of the State of California or any amended or successor code section.  Acts of maintenance or preservation, efforts to relet the Premises or the appointment of a receiver upon application of Landlord to protect Landlord’s interest under this Lease shall not constitute an election to terminate Tenant’s right to possession.  If, to the extent permitted by law, Landlord elects to relet the Premises for the account of Tenant, the rent received by Landlord from such reletting shall be applied as follows: first, to the payment of any costs of such reletting; second, to the payment of the cost of any alterations or repairs to the Premises; third, to the payment of Rent due and unpaid hereunder; and the balance, if any, shall be held by Landlord and applied in payment of future Rent as it becomes due.  If that portion of rent received from the reletting which is applied against the Rent due hereunder is less than the amount of the Rent due, Tenant shall pay the deficiency to Landlord promptly upon demand by Landlord.  Such deficiency shall be calculated and paid monthly.  Tenant shall also pay to Landlord, as soon as determined, any costs and expenses incurred by Landlord in connection with such reletting or in making alterations and repairs to the Premises, which are not covered by the rent received from the reletting.

(c)           Should Landlord terminate this Lease pursuant to the provisions of Section 14.2(a), Landlord shall have all the rights and remedies of a landlord provided by Section 1951.2 of the Civil Code of the State of California or any amended or successor code section.  Upon such termination, in addition to any other rights and remedies to which Landlord may be entitled under applicable law, Landlord shall be entitled to recover from Tenant:  (i) the worth at the time of award of the unpaid Rent and other amounts which had been earned at the time of termination; (ii) the worth at the time of award of the amount by which the unpaid Rent which would have been earned after termination until the time of award exceeds the amount of such Rent loss that Tenant proves could have been reasonably avoided; (iii) the worth at the time of award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds the amount of such Rent loss that Tenant proves could be reasonably avoided; and (iv) any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which, in the ordinary course of things, would be likely to result therefrom.  The “worth at the time of award” of the amounts referred to in clauses (i) and (ii) shall be computed with interest at the lesser of ten percent (10%) per annum or the maximum rate then allowed by law.  The “worth at the time of award” of the amount referred to in clause (iii) shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of the award plus one percent (1%).

34

14.3        Computation of Rent for Purposes of Default.  For purposes of computing unpaid Rent which would have accrued and become payable under this Lease, unpaid Rent shall consist of the sum of: (1) the total Base Rent for the balance of the Term, plus (2) a computation of Tenant’s Proportionate Share of Increased Operating Cost and Real Estate Taxes for the balance of the Term, the assumed amount for the calendar year of the default and each future calendar year in the Term to be equal to Tenant’s Proportionate Share of Increased Operating Cost and Real Estate Taxes for the calendar year immediately prior to the year in which default occurs, compounded at a per annum rate equal to the mean average rate of inflation for the preceding five (5) calendar years as determined by the United States Department of Labor, Bureau of Labor Statistics Consumer Price Index (All Urban Consumers, all items (1982-84 = 100)) for the metropolitan area in which the Project is located.  If such Index is discontinued or revised, the average rate of inflation shall be determined by reference to the index designated as the successor or substitute index by the government of the United States.

14.4        Landlord’s Right to Perform.  Notwithstanding anything to the contrary set forth elsewhere in this Lease, in the event Tenant fails to perform any affirmative duty or obligation of Tenant under this Lease, then, after the expiration of any applicable grace or cure period (unless waiting for such period to expire would jeopardize the health, safety or quiet enjoyment of the Building by its tenants and occupants or cause further damage or loss to Landlord or the Project, as reasonably determined by Landlord, or result in any violation (or continuance of any violation) of any legal requirement) Landlord may after written notice to Tenant (and without notice in case of an emergency) (but shall not be obligated to) perform such duty or obligation on Tenant’s behalf, including, without limitation, the obtaining of insurance policies or governmental licenses, permits or approvals.  Tenant shall reimburse Landlord upon demand for the costs and expenses of any such performance (including penalties, interest and attorneys’ fees incurred in connection therewith).  Such costs and expenses incurred by Landlord shall be deemed Additional Rent hereunder.

14.5        Remedies Cumulative.  All rights, privileges and elections or remedies of Landlord are cumulative and not alternative with all other rights and remedies at law or in equity to the fullest extent permitted by law.

14.6        Waiver.  Tenant waives any right of redemption or relief from forfeiture under California Civil Code Section 3275 and California Code of Civil Procedure Sections 1174 and 1179, or under any other present or future law in the event Tenant is evicted and Landlord takes possession of the Premises by reason of a default.

14.7        Repeated Defaults.  If Tenant shall cure a General Default (as defined in Section 14.1(c) above) within the time period provided for such cure pursuant to Section 14.1(c) above, but shall again fail to comply with the same provision of this Lease within three (3) months after Landlord’s written notice of the original default, then in addition to any of Landlord’s rights under this Lease in connection with such subsequent General Default, Tenant shall pay Landlord the sum of Two Thousand Five Hundred Dollars ($2,500.00) within five (5) business days of Landlord’s demand therefor, which Tenant agrees is reasonable compensation for Landlord’s agreement hereunder to provide Tenant with the opportunity to cure repetitive General Defaults of the same provision of this Lease, rather than to provide that any subsequent General Default is an Event of Default immediately and without further opportunity to cure.

ARTICLE 15.
SURRENDER; HOLDING OVER

15.1        Surrender.  Subject to the provisions of Article 8 hereof, on the Expiration Date (or earlier termination of this Lease), Tenant shall quit and surrender possession of the Premises to Landlord in as good order and condition as they were in on the Commencement Date, reasonable wear and tear, taking by condemnation and repairs which are Landlord’s responsibility excepted, and damage from casualty to improvements other than the Tenant Improvements and other improvements paid for from allowances provided by Landlord excepted.  Reasonable wear and tear shall not include any damage or deterioration that would have been prevented by good maintenance practice or by Tenant performing all of its obligations under this Lease.  Tenant shall, without cost to Landlord, remove all furniture, equipment, trade fixtures, debris and articles of personal property owned by Tenant in the Premises, and shall repair any damage to the Project resulting from such removal.  Any such property not removed by Tenant by the Expiration Date (or earlier termination of this Lease) shall be considered abandoned, and Landlord may remove any or all of such items and dispose of same in any lawful manner or store same in a public

35

warehouse or elsewhere for the account and at the expense and risk of Tenant.  If Tenant shall fail to pay the cost of storing any such property after storage for thirty (30) days or more, Landlord may sell any or all of such property at public or private sale, in such manner and at such times and places as Landlord may deem proper, without notice to or demand upon Tenant.  Landlord shall apply the proceeds of any such sale as follows: first, to the costs of such sale; second, to the costs of storing any such property; third, to the payment of any other sums of money which may then or thereafter be due to Landlord from Tenant under any of the terms of this Lease; and fourth, the balance, if any, to Tenant.  If Tenant did not elect pursuant to the Work Letter to cause Landlord to demolish the second floor server room, then at the termination or earlier expiration of the Lease Tenant shall surrender to Landlord the equipment which was located in such room immediately prior to the commencement of construction of the Tenant Improvements.

15.2        Holding Over.  If Tenant holds over after expiration or termination of this Lease without the written consent of Landlord, then for each month or any part thereof of any such hold-over period Tenant shall pay Landlord 150% of the greater of (i) fair market base rent for the Premises, as reasonably determined by Landlord, or (ii) Base Rent which Tenant was obligated to pay for the month immediately preceding the end of the Term, together with such other amounts as may become due hereunder.  No holding over by Tenant after the Term shall operate to extend the Term.  In the event of any unauthorized holding over, Tenant shall indemnify, defend and hold Landlord harmless from and against all claims, demands, liabilities, losses, costs, expenses (including attorneys’ fees), injury and damages incurred by Landlord as a result of Tenant’s delay in vacating the Premises, including but not limited to any loss, cost or damages claimed by any prospective tenant of the Premises.

ARTICLE 16.
ENTRY BY LANDLORD

16.1        Landlord Entry.  Landlord reserves and shall at all reasonable times have the right to enter the Premises, upon at least one (1) business day’s advance notice (provided that no advance notice need be given if an emergency necessitates an immediate entry or prior to entry to provide routine janitorial services), to inspect the same, to supply any service to be provided by Landlord to Tenant under this Lease, to show the Premises to prospective purchasers, mortgagees or (during the last twelve (12) months of the Term or in connection with Landlord’s rights under Article 7 or 14) tenants, and to alter, improve or repair the Premises and any portion of the Project, without abatement of rent, and may for that purpose erect, use and maintain scaffolding, pipes, conduits and other necessary structures and open any wall, ceiling or floor in and through the Project and Premises where reasonably required by the character of the work to be performed, provided access to the Premises shall not be materially impaired, and further provided that the business of Tenant shall not be interfered with unreasonably.  Such entries shall be subject to Tenant’s reasonable security measures.

16.2        Keys.  For each of the purposes set forth in Section 16.1. above, Landlord shall at all times have and retain a key with which to unlock all of the doors in the Premises, excluding Tenant’s vaults and safes or special security areas (designated in advance), and Landlord shall have the right to use any and all means which Landlord may deem proper to open said doors in an emergency to obtain entry to any portion of the Premises.  As to any portion to which access cannot be had by means of a key or keys in Landlord’s possession, Landlord is authorized to gain access by such means as Landlord shall elect and the cost of repairing any damage occurring in doing so shall be borne by Tenant and paid to Landlord as additional rent upon demand.

16.3        Waiver.  Tenant hereby waives any claim for damages for any injury or inconvenience to or interference with Tenant’s business, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned by any action of Landlord authorized by this Article 16.

ARTICLE 17.
EMERGENCY GENERATOR EQUIPMENT

17.1        Right to Use Building Generator.  Provided that Tenant leases a minimum of 75,000 square feet of space in the Building, Tenant shall have the right, at Tenant’s sole cost and expense, to connect the Premises to the Building’s emergency generator for the purpose of supplying emergency power to the Premises in the event of a power outage.  Tenant’s allocated share of power from the emergency generator shall be 60,000 watts. Tenant shall not at any time use more than 60,000 watts of electricity from the generator, or in the event of a change in laws

36

regulating emergency generator use, such lower amount as shall be legally permissible from time to time, and shall not sell electrical power or use the generator equipment to provide electrical power or services to any other party.  The method of connection to the generator shall be as directed by Landlord. Tenant, at Tenant’s sole expense, shall obtain all permits and approvals required in connection with Tenant’s connection to and use of the generator equipment and shall otherwise comply with all legal requirements regarding the installation, construction, operation and maintenance of Tenant’s connections to the generator equipment.   Landlord shall maintain and repair the generator in good working condition and upon Tenant’s written request from time to time, Landlord shall update Tenant as to the condition of the generator and shall provide Tenant with copies of the maintenance records for the generator.  In no event will Landlord be liable to Tenant for any loss or damage (including, without limitation, consequential damages for loss of business or income) incurred by Tenant as a result of the failure of the emergency generator or associated wiring to operate during an electrical failure in the Building, it being understood that Landlord’s obligation hereunder is limited to permitting Tenant to connect to the emergency generator and allowing Tenant to draw power from the generator if the power is available and the generator and associated wiring is working properly.  Tenant agrees to indemnify, defend and hold harmless Landlord and the other Indemnitees from and against any and all claims which result from or arise out of the installation, operation, existence, maintenance, repair, removal, replacement or relocation of Tenant’s generator equipment, whether occurring on the generator site, conduit areas or any other place within or without the Building.

17.2        Cost of Operation.  If the electricity to the Building is interrupted and the emergency generator is activated, Tenant shall reimburse Landlord, on demand, for Tenant’s equitable share (as reasonably determined by Landlord based on Tenant’s use or non-use thereof) of (i) the cost of the fuel used by the generator while the generator was in operation and (ii) any additional costs incurred by Landlord in operating and maintaining the emergency generator while the electricity was out.

17.3        Landlord Right to Suspend Operations.  If Landlord determines, for safety reasons or any other reason, that the emergency generator should not be used (or, if the emergency generator is already in use, that the generator should be turned off) then Landlord may shut-off the generator and shall not be required to permit Tenant to use the generator.  However, Landlord agrees that it will not prohibit Tenant form using the generator if the generator is in use for the Building systems so long as Tenant’s use of the generator will not adversely affect Landlord’s ability to continue emergency systems in the Building during the electrical failure, provided that Tenant’s rights to use the generator shall be suspended during any period that Tenant is in default in the payment of sums due under the Lease or is material default of any other provision of the Lease, and may terminated in accordance with the provisions of Section 17.5 below.

17.4        Evacuation.  If Landlord closes the Building and calls for its evacuation by means of oral notice to the Premises (which notice may be personal, telephonic, or by means of the Building’s public address system), or suggests by means of oral notice to the Premises (which notice may be personal, telephonic, or by means of the Building’s public address system) that the Building be evacuated for any reason, including because of an electrical failure, and if one or more of any Tenant Parties or other persons acting on behalf of or at the request of Tenant (collectively, “Tenant’s Personnel”) remain in or later enter the Building or the Premises during the evacuation period, then Tenant hereby waives all claims against Landlord and the Indemnitees for any injury incurred by any of Tenant’s Personnel, or injury to property, due in whole or in part to Tenant’s failure to evacuate all of Tenant’s Personnel from the Premises and the Building.  Further, Tenant will hold the Indemnitees harmless from and defend and indemnify them against any and all claims incurred by them as a direct or indirect result of Tenant’s Personnel remaining in the Premises or the Building during such evacuation period.

17.5        Rights Personal; Termination.  The rights granted pursuant to this Article 17 are personal to Tenant and its Affiliate Transferees.  If at any time Tenant leases less than 75,000 feet of Rentable Area in the Building, Landlord shall have the right to terminate Tenant’s rights under this Article 17 upon written notice to Tenant, and Tenant, at Tenant’s sole cost and expense, shall promptly remove Tenant’s connections to the Building generator in a manner approved by Landlord.

37

ARTICLE 18.
EXPANSION RIGHTS

18.1        Right of First Offer.

(a)           Right of First Offer.  Tenant shall have a right of first offer (the “Right of First Offer”) to lease any increment of space in the Building (each, a “First Offer Increment”), upon any and each occasion that a First Offer Increment becomes “available for lease” during the Term of this Lease.  Upon each occasion that a First Offer Increment becomes available for lease, Landlord shall give Tenant written notice thereof (the “Availability Notice”), which Availability Notice shall specify the available space and availability date or estimated availability date (as applicable, the “Noticed Availability Date”), and the amount of base rent and tenant improvement allowance, if any, that Landlord is prepared to offer in marketing the First Offer Increment for lease, which shall be market terms, as reasonably determined by Landlord.  Landlord and Tenant acknowledge that certain space will be available to lease in the Building as of the Commencement Date, and such space shall be considered “available for lease” only after the expiration of the initial leasing of such space occurring after the Commencement Date.

(b)           Exercise of First Offer Right.  In order for Tenant to exercise its Right of First Offer and lease a First Offer Increment, Tenant shall so notify Landlord in writing (“Tenant’s Election Notice”) within ten (10) business days after the date of the Availability Notice.  Tenant shall have no right to exercise the Right of First Offer with respect to less than the entire increment of space which comprises such First Offer Increment.

(c)           Terms and Conditions.  If Tenant timely exercises Tenant’s Right of First Offer to lease a First Offer Increment as provided above, Landlord and Tenant shall promptly enter into an amendment to this Lease, adding the First Offer Increment to the Premises on all the terms and conditions set forth in the Lease, except that (i) the term of the lease to Tenant of the First Offer Increment shall commence upon the date on which the First Offer Increment is tendered to Tenant and shall continue conterminously with the remaining Term for the Premises (as it may be extended), (ii) Tenant shall take the First Offer Increment in its then “as-is” condition or as otherwise set forth in the Availability Notice, and Landlord shall provide a tenant improvement allowance, if at all, only as set forth in the Availability Notice, (iii) the Base Rent per rentable square foot payable by Tenant for the First Offer Increment shall be equal to the rate at which Landlord was willing to market such space as set forth in the Availability Notice, (iv) there shall be no rent abatement or “free rent” period other than as specified, if at all, in the Availability Notice, (v) Tenant’s Proportionate Share shall be increased appropriately to reflect the addition of the First Offer Increment to the Premises, (vi) Tenant’s Security Deposit shall be increased proportionately to reflect the addition of the First Offer Increment to the Premises, and (vii) this Lease shall otherwise continue in full force and effect.

(d)           Landlord’s Right to Lease to Third Party; Re-offer to Tenant.  If Tenant does not exercise its right to lease the First Offer Increment within ten (10) business days after the date of any Availability Notice given with respect thereto, then Landlord shall have a period (the “Leasing Period”) of twelve (12) months to enter into a lease for such First Offer Increment with any third party on any terms and conditions Landlord desires, provided that if the net effective rent which Landlord is prepared to offer a third party (taking into account all concessions)  is less than ninety percent (90%) of the net effective rent set forth in Landlord’s Offer Notice, Landlord shall not enter into a lease on such terms without re-offering the space to Tenant on pursuant to a revised Availability Notice describing such improved terms, and Tenant shall thereupon have five (5) business days from the date of such re-offer to deliver a Tenant Election Notice to Landlord.  If, as of the end of the Leasing Period, Landlord is in bona fide negotiations with a third party to lease the First Offer Increment, then the Leasing Period shall be extended for the length of time that such bona fide negotiations continue. If Landlord does not enter into a lease with a third party for the First Offer Increment during the Leasing Period, then the provisions of this Section 18.1 shall again apply and Landlord shall give Tenant a new Availability Notice with respect thereto before leasing it to any third party.

(e)           Delivery of First Offer Increment.  If Tenant shall exercise the Right of First Offer, Landlord does not guarantee that the First Offer Increment will be available on the Noticed Availability Date for the lease thereof, if the then existing occupant of the First Offer Increment shall holdover or for any other reason beyond Landlord’s reasonable control. In such event, neither this Lease nor this Right of First Offer shall be void or

38

voidable, but rent with respect to the First Offer Increment shall be abated until Landlord delivers the same to Tenant.  Notwithstanding the foregoing, Landlord shall use commercially reasonable efforts to deliver the First Offer Increment to Tenant as soon as possible following the Noticed Availability Date for the lease thereof, and if for any reason such First Offer Increment is not delivered to Tenant within one hundred twenty (120) days from the Noticed Availability Date, then Tenant shall have the right by written notice to Landlord given at any time prior to such delivery to rescind its exercise of the Right of First Offer with respect to such First Offer Increment.

(f)            Limitation on Tenant’s Right of First Offer. Notwithstanding the foregoing, if on the date of Tenant’s Election Notice, or the date immediately preceding the date the Lease term for the First Offer Increment is to commence (i) there is an uncured Event of Default under this Lease, or (ii) Tenant does not intend to occupy for its own use at least eighty percent (80%) of the First Offer Increment within two (2) years of the Noticed Availability Date, then (in any such event) Tenant shall have no right to lease such First Offer Increment and the Tenant’s Election Notice shall at Landlord’s option be null and void.  If Tenant exercises it right pursuant to Article 19 below to terminate this Lease early with respect to less than the entire Premises, (i) Landlord shall have no obligation to provide an Availability Notice in connection with the availability resulting from Tenant’s termination of the Lease with respect to any Terminated Premises (as defined in Article 19 below) and (ii) Landlord shall have no obligation hereunder to provide an Availability Notice for the three (3) year period commencing on the Early Termination Date (as defined in Article 19 below).

(g)           Option Personal.  Tenant’s Right of First Offer as provided in this Section 18.1 shall be personal to the original Tenant executing this Lease and Affiliate Transferees, and shall not be assignable to any other person under any circumstances, unless Landlord consents to the assignment of such Right of First Offer, which consent may be granted or withheld in Landlord’s sole and absolute discretion.

18.2        Expansion Options.

(a)           Grant of Expansion Options.  Provided, that, either at the time of Tenant’s exercise of any such option or at the time the lease term for the applicable option space is to commence, (1) Tenant is not in default under this Lease (beyond any applicable cure period), and (2) Tenant intends to occupy at least eighty percent (80%) of the space for which Tenant is exercising its option within two (2) years of the date such space is added to the Premises under the Lease, Tenant shall have the following options to lease additional space in the Building:

(i)            Fourth Floor Expansion Option.  Tenant shall have the option to lease the balance of the fourth (4^th) floor of the Building not included in the Fourth Floor Premises (the “Fourth Floor Expansion Space”) for a term commencing on a date in December 2010 to be designated by Landlord.  Notwithstanding the foregoing, Tenant acknowledges that the current third party tenant of the Fourth Floor Expansion Space has an option to extend the term of such party’s lease.  If such third party extends the term of its lease of the Fourth Floor Expansion Space, Landlord shall promptly notify Tenant of such exercise and Tenant shall have no further rights to lease such space pursuant to this Section 18.2 until such time as such lease, as extended, expires.

(ii)           Second Floor Expansion Option.  Tenant shall have the option to lease the balance of the second (2^nd) floor of the Building not included in the Second Floor Premises (the “Second Floor Expansion Space”) for a term commencing the first day of the Seventh Rent Year.

(b)           Exercise of Expansion Option.  Tenant shall exercise the option to lease the Fourth Floor Expansion Space, if at all, by written notice to Landlord given not later than February 28, 2010, and shall exercise the option to lease the Second Floor Expansion Space by written notice to Landlord given by the last of the third month of the Sixth Rent Year.

(c)           Effect of Late Delivery.  If Tenant timely exercises the option to lease the Fourth Floor Expansion Space or the Second Floor Expansion Space (either such space referred to herein as “Expansion Space”), as applicable, Landlord shall use reasonable efforts to deliver such Expansion Space by the applicable projected delivery date set forth herein or otherwise stated in Landlord’s notice, provided that Tenant agrees that, if Landlord is unable to deliver possession of the Expansion Space on the projected availability date, Landlord shall not be liable for any damage thereby, nor shall Tenant’s lease of such Expansion Space be void or voidable, but rent will not

39

accrue for such Expansion Space until the date Landlord delivers possession of such Expansion Space to Tenant.  Notwithstanding the foregoing, Landlord shall use commercially reasonable efforts to deliver the Expansion Space to Tenant as soon as possible following the projected availability date for the lease thereof, and if for any reason such Expansion Space is not delivered to Tenant within one hundred twenty (120) days from projected availability date for such Expansion Space, then Tenant shall have the right to rescind its exercise of the Expansion Option with respect to such Expansion Space by written notice to Landlord given at any time prior to such delivery.

(d)           Terms and Conditions.  At Tenant’s request, Landlord shall permit Tenant to inspect the Expansion Space prior to the deadline for exercise of the option to lease the Expansion Space, provided that Tenant’s entry and inspection shall be conducted in a manner designed to minimize interference with the operations of any party then occupying the Expansion Space.  If Tenant will lease the Expansion Space pursuant to Section 18.2(a) above, then Landlord and Tenant shall enter into a written amendment of this Lease adding the Expansion Space to the Premises on all of the terms and conditions set forth in this Lease as to the Premises originally demised hereunder, except that (i) Tenant shall take the Expansion Space in its then “as-is” state and condition, (iii) the term of the lease of the Expansion Space shall commence on the date the Expansion Space is delivered to Tenant, (iv) the annual Base Rent payable by Tenant for the Expansion Space shall be the then-Fair Market Annual Rent (as defined in Section 3.2(b) above) for the Expansion Space, and (v) the Base Year for the Expansion Space shall be the calendar year in which the Expansion Space is added to the Premises.  Landlord and Tenant shall endeavor to agree upon the Fair Market Annual Rent.  If they are unable to so agree within at least six (6) months prior to the projected delivery date for the Expansion Space, Fair Market Annual Rent shall be established in accordance with the procedure described in Section 3.2(c) above.

(e)           Option Personal.  Tenant’s options as provided in this Section 18.2 shall be personal to the original Tenant executing this Lease and Affiliate Transferees and shall not be assignable to any other person under any circumstances, unless Landlord consents to the assignment of such options, which consent may be granted or withheld in Landlord’s sole and absolute discretion.

ARTICLE 19.
TERMINATION RIGHTS

19.1        Termination Option.  Tenant shall have the one-time right (the “Termination Option”) to terminate this Lease as to the entire Premises then leased hereunder or as to one or more Deletion Increments (as defined below), effective as of the end of the Seventh Rent Year (the “Early Termination Date”), by giving Landlord not less than twelve (12) months prior written notice of such termination (the “Termination Notice”).  The Termination Notice shall be irrevocable and shall specify whether the Termination Option is being exercised (i) with respect to the entire Premises then leased hereunder or (ii) with respect to one or more Deletion Increments, in which event the Termination Notice shall specifically describe the Deletion Increments to be terminated hereunder.   For the purposes of this Article 19, a “Deletion Increment” is, with respect to each floor on which a portion of the Premises is located as of the Early Termination Right, the entire Premises located on such floor.  If the Termination Notice fails to specify whether it is applicable to the entire Premises or to one or more Deletion Increments, it shall be deemed to apply to the entire Premises.  That portion of the Premises described in the Termination Notice is referred to herein as the “Terminated Premises.”

19.2        Termination Fee.  If Tenant exercises the Termination Option, Tenant shall pay Landlord a termination fee (the “Termination Fee”) equal to the sum of (i) an amount equal to six (6) times the monthly Base Rent under this Lease for the Terminated Premises, at the rate(s) applicable as of the Early Termination Date (i.e. $23.00 per rentable square foot per year), plus (ii) the Amortization Amount, plus (iii) the Unrealized Average Rent for the Terminated Premises The “Amortization Amount” shall be the unamortized amount, as of the Early Termination Date, of the total of (A) the Improvement Allowance disbursed by Landlord in connection with the construction of the Tenant Improvements pursuant to the Work Letter and any improvement allowance paid by Landlord in connection with the leasing of any other space included in the Terminated Premises, plus (B) the leasing commissions and reasonable legal fees incurred by Landlord in connection with leasing of the Terminated Premises.  If the Terminated Premises is less than the entire Premises then leased hereunder, the Amortization Amount shall be determined by calculating the amounts described in (A) and (B) above on a per square foot basis and multiplying such sum by the Rentable Area of the Terminated Premises (provided that the Amortization Amount shall be separately calculated for that portion of the Terminated Premises which is part of the Premises initially leased

40

hereunder and for those portions of the Terminated Premises, if any, added to the Premises after the Commencement Date).  For purposes of calculating the unamortized portion of the Amortization Amount, the amortization period for the Premises initially leased hereunder shall be the period commencing on the Commencement Date of the Lease and ending on the scheduled Expiration Date of the initial Lease term, and the amortization period for any portion of the Terminated Premises not part of the Premises initially leased hereunder shall be the period commencing on the Commencement Date with respect to such space and ending on the scheduled Expiration Date of the initial Lease term. The amortization shall be on a straight line basis at an annual interest rate of eight percent (8%) per annum.  Landlord shall confirm the total Amortization Amount with respect to any increment of space leased hereunder upon Tenant’s written request.  To reflect the fact that this Lease provides for an abatement of the Base Rent payable hereunder with respect to the Third Floor Premises, Fourth Floor Premises, and Fifth Floor Premises for a period of twelve (12) months, and for an abatement of the Base Rent payable hereunder with respect to the Second Floor Premises for a period of eighteen (18) months, the “Unrealized Average Rents” as of the Early Termination Date is $15.00 per square foot of Rentable Area of that portion of the Terminated Premises comprised of the Third Floor Premises, Fourth Floor Premises, and Fifth Floor Premises initially leased hereunder and $25.00 per square foot of Rentable Area of the Terminated Premises comprised of the Second Floor Premises initially leased hereunder.  Tenant shall pay fifty percent (50%) of the Termination Fee upon delivery of the Termination Notice and shall pay the remaining balance of the Termination Fee at least thirty (30) days prior to the Early Termination Date.

19.3        Termination. Tenant shall, on or before the Early Termination Date, vacate and surrender the Terminated Premises to Landlord vacant and broom-clean, in the condition required by Section 15.1 above, and all rights and duties of the parties under the Lease with respect to the Terminated Premises shall terminate effective as of midnight on the Early Termination Date, except for those obligations which by their nature survive the expiration of this Lease; provided, however, that Tenant shall remain liable for all of Tenant’s obligations which arose under the Lease with respect to the Terminated Premises, prior to midnight on the Early Termination Date, and provided further that if Tenant exercises the Termination Option, but fails to vacate and surrender the Termination Premises by the Early Termination Date, the provisions of Section 15.1 above shall apply to such holdover.  If the Termination Premises is comprised of less than the entire Premises then leased hereunder, then effective as of the date immediately following the Early Termination Date, the Base Rent payable under this Lease and Tenant’s Proportionate Share shall be reduced to reflect the termination of the Lease with respect to the Terminated Premises.

19.4        Effectiveness of Termination.  Notwithstanding anything to the contrary above, Tenant’s right to terminate this Lease pursuant to the above shall, at Landlord’s option, be inapplicable if, at the time of delivery of Tenant’s Termination Notice, or on the Early Termination Date, there exists an uncured Event of Default under the Lease, or if Tenant fails to pay the entire Termination Fee required hereunder.

ARTICLE 20.
RIGHT OF FIRST OFFER TO PURCHASE

20.1        Right of First Offer.  If Landlord receives a bona fide offer to purchase fee title to the Building and Landlord desires to accept such offer or Landlord otherwise desires to enter into an agreement to sell or exchange Landlord’s interest in the Project, before accepting such offer or entering into a binding agreement to engage in such transaction, Landlord shall immediately notify Tenant in writing of the exact terms and conditions of the proposed transaction, including relevant contingencies (the “Offer Notice”), and the following provisions shall thereafter apply:

(a)           The Offer Notice shall constitute an offer by Landlord to sell the Project to Tenant on the same terms and conditions as set forth in the bona fide offer from the third party, and for a period of fifteen (15) business days thereafter Tenant shall have the right and option, exercisable by written notice to Landlord (“Notice of Exercise”), to elect to purchase the Project upon the same terms and conditions set forth in the Offer Notice (including contingencies, if any, for title, environmental and physical condition inspections and due diligence), provided, however, the purchase price shall in all events be payable in all cash to Landlord (i.e. there shall be no seller financing).

(b)           If Tenant fails to exercise such right and option by giving Notice of Exercise to Landlord within such fifteen (15) business day period, Landlord may at any time thereafter consummate a sale of the Project for a total purchase price of not less than ninety percent (90%) of that specified in the Offer Notice. If Landlord

41

elects to reduce the purchase price to a sum which is less than ninety percent (90%) of that specified in the Offer Notice, Landlord shall give Tenant written notice of the reduced purchase price, and Tenant shall thereupon have five (5) business days to elect to purchase the Project at the reduced purchase price, but otherwise on the terms and conditions set forth herein.

20.2        Escrow; Closing.  If Tenant gives timely Notice of Exercise pursuant to Section 20.1, an escrow shall be opened at a responsible title insurance company selected by Tenant.  Landlord shall be obligated to execute, acknowledge and deposit in such escrow a standard California grant deed conveying the Project to Tenant or its assignee, together with appropriate escrow instructions and such other documents and instruments as Tenant may reasonably require to consummate such transaction.  Title to the Project shall be transferred to Tenant free and clear of monetary liens arising through Landlord, except as specifically set forth in the Offer Notice.  Except as otherwise provided in the Offer Notice, (i) Tenant shall consummate the purchase of Landlord’s Interest by closing escrow not later than ninety (90) days after the initial Offer Notice was given, (ii) rent, property taxes and assessments, and other items of income and expense of a recurring nature shall be prorated as of the closing date, (iii) the escrow fee shall be shared equally by Landlord and Tenant, Tenant shall pay for its own owner’s policy of title insurance, and all other closing costs shall be apportioned in accordance with prevailing custom in San Francisco, California.  In the event Landlord or Tenant desires to engage in a tax-deferred exchange pursuant to Section 1031 of the Internal Revenue Code, the other party shall cooperate in such exchange by executing such documents and instruments and taking such other actions as reasonably requested by the party engaging in the exchange, provided that the cooperating party shall incur no cost or expense in so doing and shall not be required to execute a promissory note or indemnity in connection therewith, and the date of close of escrow shall not be extended.

20.3        Failure to Exercise.  In the event Tenant fails or refuses for any reason to exercise its right of first refusal under this Article 20 with respect to any proposed transaction, this Article 20 shall not lapse or expire and Tenant’s rights hereunder shall remain in full force and effect with respect to any subsequent transaction throughout the term of this Lease.

20.4        Rights Personal; Termination.  The rights granted pursuant to this Article 20 are personal to Tenant and its Affiliate Transferees.  If at any time Tenant leases less than 92,000 feet of Rentable Area in the Building, Landlord shall have the right to terminate Tenant’s rights under this Article 20 shall automatically terminate.

ARTICLE 21.
ANTENNA INSTALLATIONS

21.1        Antennae Installations.  Subject to the terms and conditions of this Article 21, Tenant shall have the nonexclusive license, at Tenant’s sole cost and expense, to install and operate up to three (3) satellite antenna dishes on the roof of the Building (the “Antenna Equipment”) for receipt of transmissions, and to install cables from such satellite dish to the Premises, provided that the size, design and location of such equipment and manner of installation shall be subject to Landlord’s reasonable approval (provided that it shall in all events be reasonable for Landlord to disapprove any antenna exceeding six feet in diameter). If Tenant desires to install such equipment, Tenant shall notify Landlord in writing. Upon Landlord’s receipt of Tenant’s written information to Landlord as to the exact size and the general description of the proposed equipment, Landlord shall inform Tenant of the exact location of the antenna site(s) (the “Antenna Site(s)”).  Tenant shall further have the non exclusive right to use, in common with one or more other tenants of the Building and Landlord, the vertical shafts and horizontal raceways of the Building for the installation of such conduits, electrical wires and cables (collectively, the “Lines”) as may be approved by Landlord pursuant to this Article 21, to connect Tenant’s equipment on the Antenna Site with the Premises. The Antenna Equipment and Lines are referred to herein collectively as the “Equipment.”  The Antenna Site(s), vertical shafts and horizontal raceways of the Building which Tenant is permitted to use hereunder are referred to herein collectively as the “License Areas.”

21.2        Installation; Proper Identification of Equipment. Tenant shall submit to Landlord detailed plans and specifications detailing the location and size of the Equipment and specifically describing all proposed construction and/or installation work, including engineered drawings for the Lines that Tenant wishes to install, but shall not commence any construction, installation or operation of the Equipment until the drawings, plans and

42

specifications have been approved in writing by Landlord and until Tenant, at Tenant’s sole cost, has secured all necessary governmental approvals and permits in connection therewith and has supplied the same to Landlord. Landlord shall have no responsibility for, and Tenant shall hold Landlord harmless from, any failure of the Equipment to comply with applicable law or to function properly notwithstanding the fact that Landlord may have approved plans and specifications therefor. Landlord and Tenant shall cooperate in determining the locations of the risers and other areas of the Building (if any) through which the Lines will be installed, in order to satisfy Tenant’s reasonable requirements without unduly interfering with the operation of Building systems or other tenants’ systems and without interfering with Landlord’s ability to provide services and utilities to other tenants. Tenant shall install and operate the Equipment in a safe manner that shall not overburden or otherwise adversely effect any walls, floors, ceilings or any other structural or non structural elements in the Building or any electrical system or life safety system therein. If required by Landlord, Tenant shall erect, at Tenant’s sole cost, a visual screening fence around the Antenna Site for aesthetic purposes, the design, size, location and construction of such fence to be reasonably determined by Landlord.

21.3        Costs.  Within ten (10) days of Landlord’s invoice therefor, Tenant shall pay Landlord’s charges for monitoring or supervising Tenant’s activities in connection with the license granted hereunder by any of Landlord’s administrative, engineering, security or other personnel, which shall be billed to Tenant at the hourly standard rates for such services, as established from time to time by Landlord, and shall reimburse Landlord for out of pocket costs incurred by Landlord for services rendered by consultants, attorneys or other third parties (including but not limited to engineers, contractors, or security or janitorial personnel) in connection with the License granted hereunder, together with an amount equal to ten percent (10%) thereof to cover Landlord’s overhead (provided that such overhead cost shall be inapplicable to attorney’s fees). Tenant shall be responsible for promptly paying all additional real and personal property taxes, assessments, charges, fees or other governmental impositions levied or assessed on the Building or Landlord due to the Equipment or the construction, installation, modification, removal or operation thereof.

21.4        Construction. Tenant shall give Landlord not less than fifteen (15) days prior written notice of the commencement of any construction or installation under this Article 21. The contractor(s) performing the construction and/or installation work under this Article 21 shall be subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld or delayed. The provisions of Article 8 above shall apply to construction and installation work under this Article 21. Tenant shall cause Tenant’s contractor(s) to clearly mark (including any color coding required by the Landlord’s agent) on the exterior of each of the Lines with the number assigned by Landlord’s property manager and the starting point of the Line and the destination (e.g. “No. 501, Roof to Floor 5”), and shall place such identification tags in each closet the Lines pass through, on each horizontal run of the Lines and on each item of Equipment.

21.5        Interference by Equipment.  In no event may the Equipment interfere with any Building services or with any other providers of services to the Building or with the reception of or signal from any other antenna or satellite dish presently or hereinafter erected at the Project, including the Building. If the operation of the Equipment interferes with any such other service or antenna or satellite dish then, immediately following written notice from Landlord to Tenant of such interference, Tenant shall eliminate such interference. If Tenant is unable to promptly eliminate such interference, then Landlord may, upon further written notice to Tenant, terminate Tenant’s license with respect to the License Areas and Tenant shall immediately cease operation of the Equipment and remove the Equipment from the License Areas pursuant to Section 21.7 below. Landlord and Tenant shall cooperate with each other at all times during the term of this Lease so as to minimize interference between the Equipment and other communications equipment in the Building or on the Building’s roof, regardless of the installation dates of the Equipment or such other equipment.

21.6        Use; Compliance with Law; Permits.  Tenant agrees that Tenant shall not sell communication services or use the Equipment to provide services to any other party. Tenant represents and warrants that all of the Tenant’s activities shall be conducted in a safe manner. Tenant, at Tenant’s sole expense, shall comply with all laws and governmental rules and regulations regarding the installation, construction, operation and maintenance of the Equipment, and shall be solely responsible for obtaining and shall obtain and keep in force all permits, licenses and approvals necessary for operation of the Equipment and shall pay any increase in rates for insurance carried by Landlord resulting from the installation or use of the Equipment. Landlord shall cooperate with Tenant to the extent

43

reasonably required to obtain such permits, licenses or approvals, provided that in no event shall Landlord be required to expend any sum in connection therewith.

21.7        Removal of Equipment.  Upon the expiration or any sooner termination of the Lease, or upon Landlord’s written request if Tenant fails to perform any of its obligations under this Article 21 within five (5) business days of written notice to Tenant of such failure, Tenant shall at its expense remove all of the Equipment from the License Areas and other Building areas (if any) and restore such areas to their condition prior to installation (which restoration shall include, without limitation, removal of equipment, cabling, and all assorted wiring, and patching of all penetrations of the Building). Any property not so removed within thirty (30) days after the expiration or termination of the Lease or the license granted herein shall, at Landlord’s election, be deemed the property of Landlord, or Landlord may remove and store or dispose of such property for Tenant’s account and Tenant shall reimburse Landlord on demand for the cost of such storage or disposal.  If any governmental agency having jurisdiction requires Tenant to remove any of the Equipment, then Tenant shall at its expense remove the applicable Equipment and restore the affected areas to their condition prior to installation. Tenant shall give Landlord not less than fifteen (15) days prior written notice of the commencement of any removal and restoration under this Section 21.7. If Tenant retains possession of the License Areas licensed hereunder or any part thereof after the expiration or earlier termination of the Lease or the license granted herein, then, unless Landlord expressly agrees otherwise in writing, Tenant shall pay Landlord during such holdover period, on a monthly basis, the fair market rental for the affected space, as reasonably determined by Landlord, together with all damages sustained by Landlord on account thereof. Any failure by Tenant to remove any Equipment following written demand for the same by Landlord pursuant to the provisions of this Section 21.1(g) shall constitute continuing possession for purposes of the immediately preceding sentence.

21.8        Access to Antenna Site.  Subject to the rules and regulations of the Building, Tenant shall have the right, at Tenant’s sole cost and expense, but under the supervision of Landlord, to enter upon the License Areas during normal business hours and weekends and to construct, install, operate and maintain the Equipment, until the Lease or the license granted hereunder terminates. Tenant may have access to the License Areas for normal repairs during normal business hours upon not less than four (4) hours’ prior telephone notice to the engineer for the Building during normal business hours, and may have access to the License Areas for repairs during non business hours provided that Tenant provides Landlord with adequate advance notice thereof. Tenant shall designate in writing to Landlord the appropriate authorized person or persons the Tenant will use to make emergency repairs to the Equipment and shall cause such persons to comply with such safety and security procedures (including, without limitation, orientation and training) as Landlord shall establish from time to time. Following such designation and upon presenting satisfactory identification to Landlord’s Building security personnel together with a brief description of the reason for the emergency entry, and subject to compliance with Landlord’s safety and security procedures, such authorized person(s) may enter upon the portions of the Building where the Equipment is located to perform emergency repairs to the Equipment. Landlord may require that authorized representatives of Landlord accompany Tenant or its representatives to the License Areas.

21.9        Liability; Indemnity; Insurance.  Landlord shall have no obligation to design, install, construct, use, operate, maintain, repair, replace or remove the Equipment, nor shall Landlord have any other responsibility or liability in connection therewith or the operations thereof, except as expressly set forth in this Article 21.  Notwithstanding any provision of this Lease to the contrary, the Equipment shall be in or on the Building at the sole risk of Tenant and Landlord shall not be liable for damage thereto or theft, misappropriation or loss thereof, and Tenant hereby waives all claims against Landlord in connection therewith. In the event of an interruption in, or failure or inability to provide electricity to the Equipment, such interruption shall not impose upon Landlord any liability whatsoever (including, without limitation, liability for consequential damages or loss of business by Tenant) and Tenant hereby waives all claims against Landlord or its agents or employees for any loss or damage resulting from any such interruption. Further, notwithstanding any provision of this Lease to the contrary, except to the extent caused by the gross negligence or willful misconduct of Landlord or its agents or contractors, Tenant agrees to indemnify, defend and hold harmless Landlord, and Landlord’s agents and employees and the holders of any interest in Landlord and/or the Building from and against any and all claims, which result from or arise out of (i) the installation, operation, existence, maintenance, repair, removal, replacement or relocation of the Equipment, (ii) any construction or other work undertaken by or on behalf of Tenant in or about the License Areas, or (iii) any breach or default under this Article 21 by Tenant, whether any of the foregoing occurs on the Antenna Site, the other License

44

Areas or any other place within or without the Building and whether occurring prior to, during or subsequent to the term of this Lease. This Section 21.9 shall survive the expiration or termination of this Lease.

21.10      Maintenance; Repair. Tenant acknowledges and agrees that it accepts the Antenna Site in its “as is” condition. Tenant, at Tenant’s sole cost and expense, shall keep the Equipment in good and safe condition and repair and free of any defects (except for damage caused by the willful misconduct of Landlord or its agents or representatives), including, without limitation, correcting any loose bolts, fittings or other appurtenances. If the Antenna Site is damaged as a result of Tenant’s failure to properly maintain the Equipment, Tenant, at Tenant’s sole cost and expense, shall promptly repair such damage. Landlord makes no representation or warranty, express or implied, as to the suitability of or condition of the Building or the Antenna Site for the purposes of receipt or transmission of communications signals, or any other purpose, or whether the use of the Antenna Site is or will be permissible under applicable laws.

21.11      Relocation and Substitution.  At any time or times hereafter, in addition to the rights reserved by Landlord under any other provisions of this Lease, Landlord may require upon thirty (30) days’ prior written notice that Tenant move all or any portion of the Equipment (including any Lines) to another location or locations in or on the Building. If Landlord exercises any such rights, the parties agree that: (i) Landlord shall pay all reasonable, direct out of pocket expenses incurred by Tenant in connection therewith (excluding lost profits or other consequential damages), unless the exercise of such rights is necessary for the safety, access, use, repair, maintenance or operation of the Building including, without limitation, the repair or replacement of the roof, as determined by Landlord in its sole discretion, in which event Tenant shall bear such expenses, and (ii) Landlord shall use reasonable efforts to provide other space in the Building that will be feasible for Tenant’s purposes (but the installation of new Equipment or improvements or alterations in or to License Areas or Equipment therein shall be subject to Landlord’s approval of the drawings therefor and the other requirements set forth in the other provisions of this Article 21).

21.12      Damage or Destruction; Eminent Domain.  A fire or other casualty or a taking affecting the License Areas or the Equipment shall not affect the obligations of Tenant under this Lease, and this Lease shall remain in full force and effect, without any abatement of any amounts payable to Landlord hereunder.  Landlord shall be entitled to all compensation, damages, income, rent awards and interest thereon whatsoever which may be paid or made in connection with any taking of the License Areas, and Tenant shall have no claim against Landlord or any governmental authority for the value of any unexpired term of its rights under this Article 21; provided, however, that the foregoing shall not prohibit Tenant from prosecuting a separate claim against the taking authority for an amount separately designated for the Equipment, so long as any award to Tenant will not reduce the award to Landlord.

21.13      Rights Personal; Termination.  The rights granted pursuant to this Article 21 are personal to Tenant and its Affiliate Transferees.  If at any time Tenant leases less than 50,000 feet of Rentable Area in the Building, Landlord shall have the right on written notice to Tenant to terminate Tenant’s rights under this Article 21.

ARTICLE 22.
DECK AND STAIRWELL

22.1        Deck License Area.  Landlord hereby grants Tenant a rent-free license to use the area on the roof of the Building adjacent to the Fifth Floor Premises (the “Deck License Area”) during the term of the Lease, in accordance with the provisions of this Article 22.  Tenant shall accept the Deck License Area in its “as-is” condition. Landlord makes no representation regarding the condition of the Deck License Area or its suitability for Tenant’s use. Tenant represents and warrants that all of Tenant’s activities on the Deck License Area shall be conducted in a safe manner.  Tenant agrees to comply with the rules and regulations established by Landlord from time to time for the use of the Deck License Area, and to cause Tenant’s employees and guests to comply with such safety and security procedures as Landlord shall establish from time to time for use of the Deck License Area. The foregoing shall in no way obligate Landlord or Landlord’s Building manager to ensure the safety of persons using the Deck License Area. Without limiting the foregoing, Tenant specifically agrees that no barbeque equipment, no open flames and no smoking shall be permitted in the Deck License Area, that the License Area shall be used in a manner which does not damage the surface of the roof, and that any furnishings shall either be secured or be of a weight

45

such that they will not blow off the roof.  Tenant shall obtain Landlord’s prior written approval of all furniture, planters, flower boxes or other items placed in the Deck License Area.  Planters and flower boxes shall be installed and used in a manner which does not damage the surface of the roof.  Tenant shall not use or permit its employees or guests to use the Deck License Area in any way which will conflict with any law, statute, ordinance or governmental rule, regulation or requirement now in force or which may hereafter be enacted or promulgated (“Laws”), and upon notice that Tenant’s use of the Deck License Area is a violation of Laws, Tenant shall cease such use (and shall cause employees of Tenant to cease such use). Tenant acknowledges that notwithstanding any provision of the Lease to the contrary, Landlord shall have no obligation to repair the Deck License Area, the decking (if any), or the surrounding areas as required for or in connection with Tenant’s use of the Deck License Area, and shall have no obligation to perform any alterations or modifications to cause such area to comply with applicable Laws. Tenant shall keep the Deck License Area, including the decking tiles and any related installations (such as storage lockers and railings), in a clean condition, free of debris and in good condition and repair. Tenant shall promptly reimburse Landlord for any repairs to the decking which are required as a result of Tenant’s use of the Deck License Area and any increased operating costs or other costs incurred by Landlord as a result of Tenant’s use of the Deck License Area. Notwithstanding any provision of the Lease to the contrary, any personal property of Tenant on the Deck License Area shall be in or on the Building at the sole risk of Tenant and Landlord shall not be liable for damage thereto or theft, misappropriation or loss thereof, and Tenant hereby waives all claims against Landlord in connection therewith. Further, notwithstanding any provision of the Lease to the contrary, Tenant agrees that Tenant will be responsible for, and Tenant waives all claims against Landlord and the Indemnified Parties for all costs, damages or liability of whatever nature arising out of Tenant’s access to the Deck License Area and Tenant agrees to indemnify, defend and hold harmless the Indemnified Parties from all claims, lawsuits, damages, expenses or costs (including direct costs arising from Tenant’s use of the roof and reasonable attorney’s fees) arising from or related thereto.

22.2        Stairwell Use.  Tenant shall be permitted a license for non-emergency access to the three (3) stairwells located in the Northwest corner, central East side, and Southwest corner of the Building and reentry access via the emergency stairwell doors on the floors of the Building on which the Premises are located for the sole purpose of permitting Tenant’s employees to use the stairwells to travel between adjacent floors of the Premises, and to and from the parking garage and the main lobby, subject to the provisions of this Section. Tenant agrees to permit only employees authorized by Tenant to have access to such stairwell access system and agrees to observe all life safety regulations imposed by Landlord, the rules and regulations of the Building, and any and all applicable laws or regulations imposed by governmental authorities. Tenant acknowledges that the Building’s life safety systems may at times override Tenant’s access system. Tenant further agrees that if any governmental or insurance rule, regulation or law restricts or prohibits such access or use, or if Landlord reasonably determines that such access to or use of the stairwells presents a life safety or insurance problem for the Building or otherwise unreasonably interferes with the maintenance or operation of the Building, then Landlord may revoke Tenant’s rights under this Section upon written notice to Tenant. Upon the expiration or termination of the Lease with respect to that portion of the Premises located on any floor of the Building, Tenant’s rights under this Section with respect to such floor of the Building shall terminate, and if at any time Tenant does not lease hereunder Premises located on a minimum of two (2) contiguous floors of the Building above the ground floor, Tenant’s rights to non-emergency access to the stairwell and rights to the access system shall automatically terminate. The rights granted hereunder to Tenant are personal to Advent Software and its Affiliates and shall not inure to the benefit of any assignee of the Lease or subtenant of any portion of the Premises.  Tenant shall pay the entire cost of installation of a stairwell access system or a modification to the existing stairwell access system, and modifications to the Building’s life safety systems, if any, which are required to provide Tenant the access from the stairwells, including Landlord’s costs in reviewing or implementing such installations or modifications.  Such installations and modifications shall be subject to Landlord’s prior approval. Upon the revocation of the license granted hereunder with respect to any floor of the Building, or the expiration or termination of this Lease, Tenant shall, at Tenant’s sole cost and expense, promptly remove any magnetic key card readers or other device used to provide access from the stairwell entries for which Tenant is no longer permitted access and shall restore the magnetic key card reader area or other area to its condition prior to the installation or modification of such access system.

22.3        Right to Revoke License.  In the event Tenant breaches the provisions of this Article 22 and fails to cure such breach within five (5) business days (or within one (1) business day in the case of breaches that pose an imminent security or safety risk) after written notice from Landlord, Landlord may suspend Tenant’s license to use the Deck License Area or the stairwells until such breach is cured.  If Tenant persistently breaches the same

46

provision of this Article 22 after written notice of at least one such breach, Landlord may terminate Tenant’s license to use the Deck License Area or the stairwells, as applicable.  Tenant shall not make any repairs, alterations or improvements to the Deck License Area without Landlord’s consent, which consent shall not be unreasonably withheld.  Landlord may access the Deck License Area at any time in connection with any work Landlord desires to perform on or about the roof.  To the extent any of Landlord’s work on the roof requires that the Deck License Area be temporarily vacated, Tenant shall vacate the Deck License Area during the performance of such work.  If Tenant ceases to lease the Fifth Floor Premises immediately adjacent to the Deck License Area, the license granted under Section 22.1 shall automatically terminate.

23.2        Telecommunications.  Tenant and its telecommunications companies, including local exchange telecommunications companies and alternative access vendor services companies, shall obtain Landlord’s prior written consent (which consent shall not be unreasonably withheld) for access to and within the Building for the installation and operation of telecommunications systems, including voice, video, data, internet, and any other services provided over wire, fiber optic, microwave, wireless, and any other transmission systems (“Telecommunications Services”), for part or all of Tenant’s telecommunications within the Building and from the Building to any other location.  All providers of Telecommunications Services shall be required to comply with the rules and regulations of the Building, applicable laws and Landlord’s policies and practices for the Building.  Tenant acknowledges that Landlord shall not be required to provide or arrange for any Telecommunications Services and that Landlord shall have no liability to any Tenant Party in connection with the installation, operation or maintenance of Telecommunications Services or any equipment or facilities relating thereto.  Tenant, at its cost and for its own account, shall be solely responsible for obtaining all Telecommunications Services.  All connections shall be made in a manner reasonably approved by Landlord, shall be made at Tenant’s expense (including, without

47

limitation, any hook up, access and maintenance fees related to the installation of any equipment, wires and cables in the Premises and the commencement of service therein, and the maintenance thereafter of such equipment, wires and cables) by contractors or vendors reasonably approved by Landlord, and shall be performed in a good and workmanlike manner.

23.3        Parking and Shuttle Service.  Provided Tenant is not in default of any term or provision of this Lease, Landlord agrees to provide Tenant for use by the employees, agents, customers and invitees of Tenant the number of parking spaces designated on the Basic Lease Information page in the Project parking garage on an unreserved and unassigned basis for the monthly rental stated on the Basic Lease Information page.  Such monthly rental payments shall be deemed Additional Rent hereunder and shall be payable monthly in advance along with Base Rent.  Tenant shall not use more parking spaces than the number stated on the Basic Lease Information page.  Unless otherwise provided by Landlord, in its sole discretion, the parking spaces will not be separately identified.  Landlord shall have no obligation to monitor the use of the parking area.  All parking shall be subject to any and all rules and regulations adopted by Landlord in its discretion from time to time.  Only automobiles no larger than full size passenger automobiles or pick-up trucks may be parked in the Project garage.  Tenant shall not permit or allow any vehicles that belong to or are controlled by Tenant or Tenant’s employees, agents, customers or invitees to be loaded, unloaded or parked in areas other than those designated by Landlord for such activities.  A failure by Tenant or any of its employees, agents, customers or invitees to comply with the foregoing provisions shall afford Landlord the right, but not the obligation, without notice, in addition to any other rights and remedies available under this Lease, to remove and to tow away the vehicles involved and to charge the cost to Tenant, which cost shall be immediately due and payable upon demand by Landlord.  Tenant may at any time elect to relinquish in writing its right to use one or more of the parking spaces to be provided hereunder in which event Tenant shall not be required to pay for any such relinquished spaces.  If Tenant relinquishes in writing or by nonpayment any of such parking rights during the Term, Tenant shall no longer have a right to the parking relinquished and may obtain future parking solely on a space-available basis.  Landlord may increase the parking spaces rental rates from time to time at any time during the Term of this Lease, upon thirty (30) days prior notice to Tenant, but in no event shall such increased amount exceed the parking rate then generally charged in the area of the Project for similar facilities.  Tenant acknowledges that the individuals to whom garage access cards are distributed pursuant to Tenant’s rights hereunder will be required by Landlord or the garage operator to execute a commercially reasonable standard parking agreement acknowledging receipt of the card, providing information regarding the make, model, and license plate number of the automobile or automobiles such party may park in the garage, and acknowledging receipt of the rules and regulations pertaining to garage access and parking.  In the event Tenant shall require substantially more spaces that the stated number of parking spaces, at Tenant’s written request accompanied by Tenant’s commitment to reimburse Landlord for its additional costs in connection with operating a valet system, Landlord shall consider converting the parking garage to a valet system, provided that Landlord’s election to convert or decline to convert to such system shall be made in Landlord’s sole discretion.  Throughout the term of this Lease Landlord shall provide a shuttle service between the Building and the nearest BART station and such other public transit locations, if any, designated by Landlord, which shall be available to Tenant’s employees free of charge, subject to the reasonable rules and regulations imposed by the shuttle service regarding proper identification.  The shuttle shall operate during morning and afternoon commute hours, provided that the specific hours of operation and schedule for the shuttle service shall be determined by Landlord, however Landlord shall consult with Tenant regarding the schedule of the shuttle service. The cost of operating the shuttle service shall be an Operating Cost, and Operating Cost for the Base Year shall be deemed to include the cost of a full calendar year’s shuttle service at the rate initially payable therefor.

23.4        Brokers.  Landlord has been represented in this transaction by Landlord’s Broker.  Tenant has been represented in this transaction by Tenant’s Broker.  Upon full execution of this Lease by both parties, (i) Landlord shall pay to Landlord’s Broker a fee for brokerage services rendered by it in this transaction if provided for in a separate written agreement between Landlord and Landlord’s Broker, and (ii) Landlord shall pay to Tenant’s Broker a fee for brokerage services rendered by it in this transaction if provided for in a separate written agreement between Landlord and Tenant’s Broker.  Landlord and Tenant each represents and warrants to the other that such party has negotiated this Lease directly with the real estate Brokers named in the Basic Lease Information page and has not authorized or employed, or acted by implication to authorize or to employ, any other real estate broker or salesman to act for such party in connection with this Lease. Each party shall hold the other harmless from and indemnify and defend the other against any and all claims by any real estate broker or salesman other than the real estate Brokers named in the Basic Lease Information page for a commission, finder’s fee or other compensation as a

48

result of the inaccuracy of such party’s representation above, including any costs, expenses and attorneys’ fees incurred with respect such claims.

23.5        No Waiver.  No waiver by either party of the default or breach of any term, covenant or condition of this Lease by the other party shall be deemed a waiver of any other term, covenant or condition hereof, or of any subsequent default or breach by Tenant of the same or of any other term, covenant or condition hereof.  Landlord’s consent to, or approval of, any act shall not be deemed to render unnecessary the obtaining of Landlord’s consent to or approval of, any subsequent or similar act by Tenant, or be construed as the basis of an estoppel to enforce the provision or provisions of this Lease requiring such consent.  Regardless of Landlord’s knowledge of a default or breach at the time of accepting Rent, the acceptance of Rent by Landlord shall not be a waiver of any preceding default or breach by Tenant of any provision hereof, other than the failure of Tenant to pay the particular Rent so accepted.  Any payment given Landlord by Tenant may be accepted by Landlord on account of monies or damages due Landlord, notwithstanding any qualifying statements or conditions made by Tenant in connection therewith, which statements and/or conditions shall be of no force or effect whatsoever unless specifically agreed to in writing by Landlord at or before the time of deposit of such payment.  No payment by Tenant of a lesser amount than the amount required under this Lease shall be deemed to be other than on account of the Rent due, and Landlord may accept such payment without prejudice to Landlord’s right to recover the balance due or to pursue any other remedy herein provided.

23.6        Recording.  Neither this Lease nor a memorandum thereof shall be recorded without the prior written consent of Landlord, which consent shall not be unreasonably withheld.  Tenant shall have the right to record a short form memorandum of lease in a form reasonably approved by Landlord.

23.7        Estoppel Certificate.  Within ten (10) business days following Landlord’s request, Tenant shall execute, acknowledge and deliver written estoppel certificates addressed to (i) any Holder or prospective mortgagee of Landlord, or (ii) any purchaser or prospective purchaser of all or any portion of, or interest in, the Project, on a commercially reasonable form specified by Landlord, certifying as to such facts (if true) and agreeing to such notice provisions and other matters as such mortgagee(s) or purchaser(s) may reasonably require, including, without limitation, the following: (a) that this Lease is unmodified and in full force and effect (or in full force and effect as modified, and stating the modifications); (b) the amount of, and date to which Rent and other charges have been paid in advance; (c) the amount of any Security Deposit; and (d) acknowledging that to Tenant’s current knowledge without duty of inquiry, Landlord is not in default under this Lease (or, if Landlord is claimed to be in default, stating the nature of the alleged default).  Any such estoppel certificate may be relied upon by any such mortgagee or purchaser.  If Tenant fails to execute any such certificate complying with the above provisions within the period described above, and thereafter Tenant does not deliver such executed document within ten (10) days of written notice from Landlord of such failure, such failure shall, at Landlord’s election, constitute an Event of Default hereunder and shall be conclusive upon Tenant that (1) this Lease is in full force and effect and has not been modified except as represented by Landlord; (2) not more than one month’s Rent has been paid in advance; and (3) Landlord is not in default under this Lease.  At any time and from time to time, in the context of a sale of Tenant’s business or a financing thereof only, and upon not less than fifteen (15) business days’ prior notice from Tenant, Landlord shall execute and deliver to Tenant a statement addressed to any lender, investor or acquirer of Tenant or prospective lender, lender or acquirer of Tenant, on a commercially reasonable form specified by Tenant, certifying (i) the titles and dates of the documents then comprising the Lease, (ii) the current amounts of and the dates to which the Rent and other charges have been paid, (iii) the amount to the Security Deposit then held by Landlord, and (iii) to the best of Landlord’s knowledge without duty of inquiry that Tenant is not in default under this Lease (or if Tenant is in default, specifying the nature of such default).

23.8        Transfers by Landlord.  In the event of the transfer and assignment by Landlord of its interest in this Lease and in the Building to a party expressly assuming Landlord’s obligations under this Lease, Landlord shall thereby be released from any further obligations hereunder accruing thereafter, and Tenant agrees to look solely to such successor in interest of the Landlord for performance of such obligations. Any security given by Tenant to secure performance of Tenant’s obligations hereunder shall be assigned and transferred by Landlord to such successor in interest and Landlord shall thereby be discharged of any further obligation relating thereto.

23.9        Attorneys’ Fees.  In the event either party places the enforcement of this Lease, or any part of it, or the collection of any Rent due, or to become due, hereunder, or recovery of the possession of the Premises, in the

49

hands of an attorney, or files suit upon the same, the prevailing party shall recover its reasonable attorneys’ fees, costs and expenses, including those which may be incurred on appeal.  The term “prevailing party” shall include, without limitation, a party who substantially obtains or defeats the relief sought, as the case may be, whether by compromise, settlement, judgment or otherwise.  The attorneys’ fee award shall not be computed in accordance with any court fee schedule, but shall be such as to fully reimburse all attorneys’ fees reasonably incurred.

23.10      Termination; Merger.  No act or conduct of Landlord, including, without limitation, the acceptance of keys to the Premises, shall constitute an acceptance of the surrender of the Premises by Tenant before the Expiration Date.  Only a written notice from Landlord to Tenant shall constitute acceptance of the surrender of the Premises and accomplish a termination of this Lease.  Unless specifically stated otherwise in writing by Landlord, the voluntary or other surrender of this Lease by Tenant, the mutual termination or cancellation hereof, or a termination hereof by Landlord for default by Tenant, shall automatically terminate any sublease or lesser estate in the Premises; provided, however, Landlord shall, in the event of any such surrender, termination or cancellation, have the option to continue any one or all of any existing subtenancies.  Landlord’s failure within thirty (30) days following any such event to make any written election to the contrary by written notice to the holder of any such lesser interest, shall constitute Landlord’s election to have such event constitute the termination of such interest.

23.11      Amendments; Interpretation.  This Lease may not be altered, changed or amended, except by an instrument in writing signed by the parties in interest at the time of the modification.  The captions of this Lease are for convenience only and shall not be used to define or limit any of its provisions.

23.12      Severability.  If any term or provision of this Lease, or the application thereof to any person or circumstances, shall to any extent be invalid or unenforceable, the remainder of this Lease, or the application of such provision to persons or circumstances other than those as to which it is invalid or unenforceable, shall not be affected thereby, and each provision of this Lease shall be valid and shall be enforceable to the fullest extent permitted by law.

23.13      Notices.  All notices, demands, consents and approvals which are required or permitted by this Lease to be given by either party to the other shall be in writing and shall be deemed to have been fully given by personal delivery or by recognized overnight courier service or when deposited in the United States mail, certified or registered, return receipt requested, with postage prepaid, and addressed to the party to be notified at the address for such party specified on the Basic Lease Information page, or to such other place as the party to be notified may from time to time designate by at least fifteen (15) days’ notice to the notifying party given in accordance with this Section 23.13.  A copy of all notices given to Landlord under this Lease shall be concurrently transmitted to such party or parties at such addresses as Landlord may from time to time hereafter designate by notice to Tenant.

Any notice sent by registered or certified mail, return receipt requested, shall be deemed given on the date of delivery shown on the receipt card, or if no delivery date is shown, the postmark thereon.  Notices delivered by recognized overnight courier shall be deemed given one (1) business day after delivery of the same to the courier. Notices delivered by United States mail shall be deemed given three (3) business days after depositing the same as required hereunder.  If notice is received on a Saturday, Sunday or legal holiday, it shall be deemed received on the next business day.

23.14      Force Majeure.  Any prevention, delay or stoppage of work to be performed by Landlord or Tenant which is due to strikes, labor disputes, inability to obtain labor, materials, equipment or reasonable substitutes therefor, acts of God, governmental restrictions or regulations or controls, judicial orders, enemy or hostile government actions, civil commotion, or other causes beyond the reasonable control of the party obligated to perform hereunder, shall excuse performance of the work by that party for a period equal to the duration of that prevention, delay or stoppage.  Nothing in this Section 17.12 shall excuse or delay Tenant’s obligation to pay Rent or other charges due under this Lease.

23.15      Successors and Assigns.  This Lease shall be binding upon and inure to the benefit of Landlord, its successors and assigns (subject to the provisions hereof, including, without limitation, Section 17.6), and shall be binding upon and inure to the benefit of Tenant, its successors, and to the extent assignment or subletting may be approved by Landlord hereunder, Tenant’s assigns or subtenants.

Landlord’s Contractor will provide Tenant’s Representative with a copy of Landlord’s Contractor’s suggested subcontractors for the work shown on the Demolition Plan (the “Demolition Work”), Landlord’s Contractor’s estimated budget for the Demolition Work, including Landlord’s Contractor’s fee of 3.1% of the total hard cost of the Demolition Work for overhead and profit and Landlord’s Contractor’s general conditions for the Demolition Work.  Tenant shall have two (2) business days after the receipt of Landlord’s Contractor’s bid analysis to approve or reasonably disapprove Landlord’s Contractor’s selection of subcontractors and Landlord’s Contractor’s estimated budget for the demolition work.  Landlord’s Contractor shall commence demolition of the existing improvements as soon as reasonably possible following approval of the Demolition Plan, the budget for the Demolition Work, and the selection of the subcontractors to perform such Demolition Work.

(d)  Approval.  Landlord’s approval of any item reviewed by Landlord under this Work Letter shall merely indicate Landlord’s consent to the proposed work shown thereon, and in no event shall such consent by Landlord be deemed to constitute a representation by Landlord that the work called for therein complies with applicable building codes or other legal requirements, nor shall such consent release Tenant from Tenant’s obligation to supply Working Drawings that do so substantially conform to applicable building codes and legal requirements.

(e)  Design-Build; MEP Plans.   Landlord and Tenant acknowledge that portions of the mechanical, electrical, and plumbing components of the Tenant Improvements (the “Design-Build Components”) shall be designed and constructed on a design-build basis by subcontractors selected by Landlord’s Contractor and approved by Tenant pursuant to Section 3 below.  Upon receipt of the Space Plans and approval of the Bid List (as defined below), Landlord shall cause Landlord’s Contractor to solicit bids from not less than three (3) such subcontractors for the Design-Build Components, except as otherwise approved by Tenant, and provide Tenant with Landlord’s Contractor’s bid analysis (including copies of the actual subcontractor bid responses) and recommended subcontractors for the Design Build Components.  Tenant shall approve or reasonably disapprove the proposed design-build subcontractor within two (2) business days of Landlord’s Contractor’s request for such approval.  The subcontractors selected to perform the design-build work are referred to herein as the “Design-Build Subcontractors”.  Landlord and Tenant shall cooperate regarding the selection of any required Design-Build Subcontractors with the goal of selecting such Design-Build Subcontractors by January 3, 2006, and during development of plans by the Design-Build Subcontractors, Tenant shall cause Tenant’s Architect to cooperate with the Design-Build Subcontractors and to respond to inquiries from the Design-Build Subcontractors promptly, and in all events within two (2) business days.  Tenant shall provide the Design-Build Subcontractors with the information required for the Design-Build Subcontractors to commence design on February 2, 2006 and to complete design prior to February 24, 2006.  The plans prepared by the Design-Build Subcontractors for such portions of the electrical, and plumbing components of the Tenant Improvements shall be subject to Landlord’s and Tenant’s approval, which approval shall not be unreasonably withheld. Landlord and Tenant shall respond to such plans within five (5) business days of its receipt thereof.  Landlord shall cause the Design-Build Subcontractor(s) respond promptly to any reasonable objections of Landlord or Tenant to such plans to resubmit appropriately revised plans within five (5) days of receipt of Landlord’s or Tenant’s objections.  Such resubmitted plans shall clearly indicate which portions of the plans remain unchanged from the previously submitted plans.  Landlord and Tenant shall respond to revised plans within three (3) business days of receipt thereof.  The foregoing procedure shall be repeated until such plans have been approved by Landlord and Tenant. Such approved plans are referred to herein as the “Design-Build Plans”.

5.             Cooperation.  Landlord and Tenant and their respective contractors, consultants and representatives, shall communicate and cooperate with each other to the end that the Tenant Improvements are constructed in an expeditious manner, having due regard for minimizing disturbance of other tenants of the Project.  Landlord and Tenant shall cooperate with each other to resolve any space planning or other issues that are raised by applicable local, state or federal building codes during the planning, permit or construction process. Landlord’s Contractor shall keep Tenant informed regarding the progress of the work, and Landlord’s Contractor and Tenant’s Representative shall hold construction meetings with frequency reasonably satisfactory to Tenant.

6.             Landlord’s Work.  In addition to the payment of the Improvement Allowance (as defined below) , Landlord shall, at Landlord’s sole cost and expense, perform the following work (“Landlord’s Work”):

 (i) all work necessary to cause the common restrooms in the Building and existing restrooms in the Premises to comply with applicable laws and codes regarding handicap access and use (using Building standard plans and finishes) to the extent such work is required in connection with the Tenant Improvements (but not with respect to additional stalls or fixtures required as a result of density of employees in excess of one per 138 square feet of Rentable Area of the Premises on any floor or as a result of assembly rooms or similar improvements included in the Tenant Improvements);

(ii) to the extent, if any, indicated in the Final Plans, demolish the large server room on the second floor of the Building below ceiling, including the removal or all racks and equipment in such room, and replace the ducting, HVAC ducting, and sprinkler grid, if any, removed in connection with such demolition.  If Tenant does not elect to cause Landlord to demolish the second floor equipment room, Tenant may use the equipment located in such room during the term of the Lease, and shall surrender such equipment to Landlord at the termination or earlier expiration of the Lease;

(iii) following demolition required pursuant to the Final Plans, seal all penetrations through the slab in the Premises in compliance with applicable law;

(iv) to the extent not previously performed, the work set forth in Section 5.7 of the Lease.

7.             Construction.

(a)  Construction Operations Fee.  Notwithstanding the provisions of Section 8.5 of the Lease to the contrary, Landlord acknowledges and agrees that no administration fee shall be charged by Landlord in connection with the performance of the Tenant Improvements.

(b)  Construction Cost; General Conditions.  Prime Contractor and Landlord’s Contractor shall construct the Tenant Improvements on a cost basis, plus (i) a fee of 3.1% of the total hard cost of the Tenant Improvements for overhead and profit (“Contractor’s Fee”), (ii) general conditions in accordance with the schedule attached hereto as Schedule B-1 (the “General Conditions”), and (iii) labor costs at the rates specified in the schedule attached hereto as Schedule B-2 for labor supplied by Landlord’s Contractor’s personnel for construction in excess of the 16 weeks of construction assumed in Tenant’s Request for Proposal.  Tenant acknowledges that the estimated cost of the General Conditions as shown on Schedule B-1 is based on the assumptions specified therein, and the actual cost of the General Conditions may vary to the extent actual conditions vary from such assumptions.

3

(c)  Preconstruction Services.  Landlord shall cause Landlord’s Contractor to perform the following preconstruction services, the cost of which is specified in the General Conditions attached hereto as Schedule B-1: Participate in a reasonable number of design meetings, provide an estimated budget to Tenant within five (5) business days of Landlord’s receipt of the 75% Design Development Drawings, provide an estimated budget to Tenant within five (5) business days of Landlord’s receipt of the 50% Construction Documents, provide to Tenant reasonable value engineering, and provide to Tenant an estimated schedule for the construction of the Tenant Improvements.  If Landlord’s Contractor reasonably determines that the input of a subcontractor in one or more trades is required on an hourly fee basis in connection with the preparation of an estimated budget or in connection with value engineering, Landlord’s Contractor shall so notify Tenant’s Representative, and Landlord’s Contractor and Tenant’s Representative shall cooperate in the prompt selection and engagement of such subcontractor(s), and the hourly fee charged by such subcontractor(s) in connection therewith shall be included in the cost of the Tenant Improvements.  Tenant’s Representative shall in all events approve or reasonably disapprove a proposed consulting subcontractor within three (3) days of Landlord’s Contractor’s request for such approval.  Landlord shall cause Landlord’s Contractor to use reasonable care in preparing the estimated budgets, but they shall be good faith estimates only.

(d)  Bidding and Budgets. Landlord shall cause Landlord’s Contractor to solicit bids from not less than three (3) subcontractors for each major trade working on the Tenant Improvements (except for the trades of approved Design-Build Subcontractors, which shall have been previously selected pursuant to the provisions of Section 2(e) above and except for the Demolition Work).  When Landlord’s Contractor has received responses to its bid request, Landlord’s Contractor will analyze the same and provide Tenant’s Representative with a copy of Landlord’s Contractor’s bid analysis (including copies of the actual subcontractor responses), recommended winning bidders and estimated budget for the Tenant Improvements, based upon the selected subcontractors’ bids (including the Design-Build Subcontractors) and including Contractor’s Charge (as defined above), the estimated cost of General Conditions, and a reasonable contingency not to exceed ten percent (10%).  Tenant shall have three (3) business days after the receipt of Landlord’s Contractor’s bid analysis to approve or reasonably disapprove Landlord’s Contractor’s selection of subcontractors and Landlord’s Contractor’s estimated budget.  Further, if Tenant disapproves of the budget and in order to satisfactorily reduce the cost of the work as shown on the budget the Final Plans must be modified to change the scope of the work or modify finishes or materials indicated on the Final Plans, Tenant shall cause Tenant’s Architect to modify the Final Plans in order to satisfactorily reduce the cost of the work as shown on the budget.  Any and all revisions to the Final Plans shall be subject to Landlord’s approval (in accordance with Section 9 below) and at Tenant’s cost.  Upon Tenant’s disapproval of any subcontractor bid or the revision of the Final Plans, Landlord shall cause Landlord’s Contractor to promptly prepare and submit to Tenant a revised estimated budget.  Tenant shall respond to the revised estimated budget in the manner described above.  Any delay in Substantial Completion (as defined below) of the Tenant Improvements resulting from any revision to the Final Plans or the budget shall constitute a Tenant Delay as defined in and subject to Section 11 below.  If Tenant fails to raise any objections to the analysis and/or budget within the period(s) described above, Tenant shall be deemed to have approved Landlord’s Contractor’s recommended bid acceptance and proposed budget.  Upon approval of the estimated budget and selection of the subcontractors, Landlord’s Contractor shall provide Tenant with Landlord’s Contractor’s reasonable and good faith estimate of the date by which it anticipates the Tenant Improvements will be completed (the “Anticipated Completion Date”).

8.             Commencement of Construction; On-going Obligations.  Upon approval of the Final Plans and selection of subcontractors and approval of the budget, and after securing all necessary permits, Landlord shall cause Prime Contractor and Landlord’s Contractor to promptly commence and diligently pursue to completion construction of the Tenant Improvements.  Landlord’s Contractor shall update the project schedule weekly, and shall provide to Tenant a tracking of the budget on a weekly basis in the form of a consolidated one-page summary report including, without limitation, backup detail and pending and approved change order requests showing impact to budget and estimated impact to the Anticipated Completion Date.

9.             Changes.  If Tenant shall desire any change in or to the Final Plans (a “Change”), Tenant shall submit to Landlord for Landlord’s review and written approval revised Working Drawings prepared by Tenant’s Architect incorporating the requested Change and clearly identifying the same as such on the revised Working Drawings.   Landlord shall not unreasonably withhold or delay its approval of the revised Working Drawings, provided, however, that Landlord shall have at least three (3) business days after receipt of the revised Working Drawings to review any proposed Change, and Landlord shall have at least six (6) business days to review any proposed change to the structure or the mechanical or life safety systems or changes which would increase or

4

decrease the budget by more than $20,000 (such changes being referred to herein as “Material Changes”).  If Landlord fails to approve or disapprove a requested Change which is not a Material Change within the three (3) business day period specified above, Landlord shall be deemed to have approved such proposed Change.  If Landlord approves any proposed Change, then together with such approval, if practicable, and if not practicable as soon thereafter as is practicable, Landlord’ Contractor shall give Tenant Landlord’s estimated increase or decrease in the cost of the Tenant Improvements and the estimated delay (if any) which would result from incorporating such Change.  Landlord will use reasonable care in preparing the estimates, but they shall be good faith estimates only and will not limit Tenant’s obligation to pay for the actual increase in the cost of the Tenant Improvements (subject to the Improvement Allowance) or Tenant’s responsibility for the actual construction delay resulting from the Change.  Within two (2) business days after receipt of such cost and delay estimates, Tenant shall notify Landlord in writing whether Tenant approves the Change.  If Tenant fails to approve the Change within such two (2) business day period, construction of the Tenant Improvements shall proceed as provided in accordance with the Final Plans as they existed prior to the requested Change.  If, following Tenant’s review of the estimated costs and delays, Tenant desires Landlord to incorporate the Change into the Tenant Improvements, then Tenant’s Architect and Landlord shall execute a change order for such Change on Landlord’s Contractor’s standard form therefor, and the term “Final Plans” shall thereafter be deemed to refer to the Working Drawings as so revised and approved.

10.           Substantial Completion.  “Substantial Completion” of the Tenant Improvements shall be deemed to have occurred when (i) the Tenant Improvements have been completed pursuant to the Final Plans, subject only to the completion or correction of Punch List Items, and (ii) Landlord has obtained all approvals and permits from the appropriate governmental authorities required for the legal occupancy of the Premises for Tenant’s intended use.  Punch List Items shall mean incomplete or defective work or materials in the improvements, of a nonmaterial nature, called for in the Final Plans which do not materially impair Tenant’s use of the Premises for the conduct of Tenant’s business therein.  Upon notice from Landlord that the Tenant Improvements have been Substantially Completed, Landlord and Tenant shall tour the Premises and prepare a joint list of Punch List items. Following Substantial Completion, the parties shall promptly execute a Confirmation of Term of Lease substantially in the form attached as Exhibit C to the Lease.  Landlord shall cause Landlord’s Contractor to diligently pursue the Punch List Items to completion to Tenant’s reasonable satisfaction, and Tenant shall reasonably cooperate with and accommodate Landlord’s Contractor in connection therewith.  Upon Substantial Completion, Tenant shall cause Tenant’s Architect to deliver to Landlord a set of “as-built” drawings for the Tenant Improvements.

11.           Tenant Delays; Landlord Delays.

(a) Tenant Delays.  Except to the extent resulting from a Landlord Delay (as defined below) “Tenant Delay” shall be any actual delay in the completion of the Tenant Improvements or Landlord’s Work caused by the following: (i) the failure of Tenant to submit to Landlord the Space Plans by the Space Plan Deadline, the Working Drawings by the Final Plan Deadline, or revisions to the Space Plans or the Working Drawings by the dates or within the time periods set forth above, (ii) any changes in the Space Plan or Working Drawings after submission thereof to Landlord (except changes to respond to Landlord’s comments) and any Changes to the Final Plans (whether or not such change or Change is a result of Tenant’s disapproval of the budget and including any cost or delay resulting from proposed changes or Changes that are not ultimately made, but excluding Changes which result from unknown field conditions which could not reasonably have been anticipated by Tenant’s Architect), (iii) any failure by Tenant to timely pay any amounts due from Tenant hereunder (it being acknowledged that if Tenant fails to make or otherwise delays making such payments, Landlord may stop work on the Tenant Improvements rather than incur costs which Tenant is obligated to fund but has not yet done so and any delay from such a work stoppage will be a Tenant Delay), (iv) any failure of Tenant to submit any item or to approve or disapprove any matter within the time frame or by the deadline provided in the Work Letter, (v) any material changes to the Space Plans after submittal thereof which delay the completion of plans by the Design-Build Subcontractors, (vi) delay by Tenant in promptly responding to inquiries regarding the construction of the Tenant Improvements or Landlord’s Work or in granting Tenant’s prompt approval or disapproval of materials or finishes for the Tenant Improvements or Landlord’s Work, (vii) the inclusion in the Tenant Improvements of any so-called “long-lead” materials (such as fabrics, panelling, tiling or carpeting, or other items that must be imported, must be specially fabricated, or are of unusual character or limited availability) to the extent there exists a reasonable substitute for such material which would not be considered a long-lead material or would have a shorter lead time , as reasonably determined by Landlord’s Contractor, (viii) any interference by Tenant or Tenant’s vendors with the construction of the Tenant Improvements or Landlord’s Work resulting in a delay beyond the reasonable integration schedule developed under Section 13 of this Work Letter, (ix) any delay in the issuance of permits due to the submittal of drawings (other than

5

drawings prepared by Design-Build Subcontractors) which do not comply with applicable codes, to the extent the code requirement could have reasonably been anticipated by Tenant’s Architect, (x) Tenant’s failure to provide, by the dates specified herein, the information required for the Design-Build Subcontractors to commence and complete their designs, (xi) the failure Tenant’s Architect failure to cooperate with the Design-Build Subcontractors or to respond to inquiries from the Design-Build Subcontractors as and within the periods required herein, or (xii) any other delay requested or caused by Tenant, Tenant’s Representative or Tenant’s Architect.  Each of the foregoing is referred to herein and in the Lease as a “Tenant Delay”.  Landlord’s Contractor will give Tenant notice of “long-lead items” as soon as reasonably practicable after being advised of the delay by the suppliers involved, or otherwise becoming aware of the delay.  Landlord’s Contractor will suggest alternative products to alleviate the delay, if feasible.  The inclusion of “long lead” items in the Tenant Improvements shall be deemed a Tenant Delay only if (A) Tenant fails to designate a reasonable substitute for such item within two (2) days after receipt of written notice from Landlord’s Contractor that such item is a “long lead” item, or (B) Landlord and Tenant do not agree that the Tenant Improvements will be Substantially Complete notwithstanding the non-completion of long-lead items and related work (Landlord’s Contractor and Tenant agree that in such instances, if reasonably appropriate, a short term alternative product will be installed prior to Substantial Completion and will be replaced with the long lead item at a later date).  In determining whether reasonable substitutes exist for long-lead items, Landlord’s Contractor shall consider the function of the material and shall not be required to consider the unique aspects of the material or the particular aesthetic of the material (i.e. a more common material can be a reasonable substitute for an item of limited availability).  Notwithstanding the foregoing, matters otherwise designated hereunder as Tenant Delays which first occur following Landlord’s Contractor’s establishment of the Estimated Completion Date shall be Tenant Delays only to the extent Substantial Completion of the Tenant Improvements is delayed beyond the Estimated Completion Date as a result thereof.

(b)  Landlord Delays.  “Landlord Delays” shall constitute the actual delay in the completion of the Tenant Improvements beyond the anticipated completion date to the extent caused by the following: (i) the failure by Landlord to approve or reasonably disapprove the Space Plans or the Working Drawings or to otherwise comply with its obligations under this Work Letter by the dates or within the time periods set forth above, (ii) any Changes requested by Landlord in the Space Plans, Working Drawings or Final Plans, after approval thereof by Landlord and Tenant (excluding Changes which result from unknown field conditions which could not reasonably have been anticipated by Landlord’s Contractor or Changes required to obtain permits for the work), (iii) any delay caused by the Prime Contractor, Landlord’s Contractor or the subcontractors including, without limitation, the failure of the Prime Contractor, Landlord’s Contractor or the subcontractors to process and execute (or disapprove) any Changes in a reasonably expeditious manner, (iv) any delay resulting from the performance of Landlord’s Work, and (v) the interruption in the availability of the freight elevator due to a required repair, except to the extent such repair is necessitated due to the actions of Tenant or Tenant’s vendors or contractors.  In the event and to the extent a Landlord Delay during the Move In Period results in a delay in Tenant completing its preparation of the Premises for occupancy in accordance with Section 2.4 of the Lease by the Commencement Date, the Commencement Date under the Lease shall be delayed by one (1) day of each day of such Landlord Delay.

12.           Cost of Improvements.  The cost of the construction and installation of the Tenant Improvements shall be borne as follows:

(a)  Landlord shall pay the entire cost of Landlord’s Work.

(b)  Landlord shall contribute toward the cost of the construction and installation of the Tenant Improvements an amount not to exceed Forty Dollars ($40.00) per square foot of Rentable Area of the Premises (the “Improvement Allowance”).  The following provisions shall govern the payment of the Improvement Allowance:

(i)  Excess Cost; Share of Costs.  Tenant shall pay the cost of construction of the Tenant Improvements to the extent such cost exceeds the funds available therefor from the Improvement Allowance (the “Excess Cost”).  Based on the estimated cost (the “Estimated Costs”) of the construction of the Tenant Improvements, the prorata share of the Estimated Costs payable by Landlord and Tenant shall be determined and an appropriate percentage share established for each (a “Share of Costs”).  Tenant and Landlord shall fund the cost of such work as the same is performed, in accordance with their respective Share of Costs for such work.  Tenant’s payments shall be made from time to time within thirty (30) days of Tenant’s receipt of a payment request from Landlord’s Contractor (accompanied by supporting documentation of the type typically submitted by contractors in support of payment requests, including, without limitation, AIA Document G702 Application and

6

Certificate for Payment, the applicable conditional and unconditional lien waivers, schedule of values including name of company associated with each trade, and a copy of subcontractor invoices) reflecting that such work has been performed and such construction is in place, or that the relevant materials have been delivered to the site, and clearly reflecting the percentage payable by Tenant on account of such invoice.  At such time as the Improvement Allowance has been entirely disbursed, Tenant shall pay the remaining Excess Cost, if any, which payments shall be made in installments as construction progresses in the same manner as Tenant’s payments of Tenant’s Share of Costs were paid.  If the total actual Excess Cost turns out to be less than the total payments made by Tenant, Landlord shall refund the excess to Tenant following the final construction accounting, and if the total payments made by Tenant turns out to be less than the Excess Costs, Tenant shall pay the shortfall to Landlord following the final construction accounting.

(ii)  Certain Costs.  Portions of the Improvement Allowance may, at Tenant’s election, be applied toward Tenant’s reasonable architectural and engineering fees in connection with the design and construction of the Tenant Improvements, including the costs of producing the Space Plans, Working Drawings and Final Plans, the reasonable cost of Tenant’s consultants associated with the Tenant Improvements or entering into this Lease, and Tenant’s reasonable moving costs reasonably associated with Tenant’s relocation into the Premises.  Landlord shall reimburse Tenant for such portion of such fees and costs (or, if Tenant so notifies Landlord in writing, will make payments directly to Tenant’s Architect, engineer or vendor) upon Landlord’s receipt of copies of receipted invoices covering the same. In no event may any portions of the Improvement Allowance be applied towards the costs of Tenant’s personal property or movable furniture, signage or rental obligations.

(iii) Rent Credit.  Provided that Tenant has performed the Minimum Required Improvements and provided that Tenant is not in default hereunder, at Tenant’s written election the balance of the Improvement Allowance shall be credited against the Rent first due under the Lease.

(iv)  Landlord Costs.  Notwithstanding anything to the contrary herein, the Excess Cost shall not include, Landlord shall be solely responsible for, and the Improvement Allowance shall not be used for the following: (a) costs incurred to remove or encapsulate Hazardous Materials from the Premises, the Building and the Project; (b) costs to bring the Base Building into compliance with applicable laws and restrictions (except as otherwise set forth in Section 6.6 of the Lease), (c) attorneys’ fees incurred in connection with negotiation of construction contracts, and attorneys’ fees, experts’ fees and other costs in connection with disputes with third parties; (d) interest and other costs of financing construction costs; (e) penalties and late charges attributable to Landlord’s failure to pay construction costs; (f) wages, labor and overhead for overtime and premium time, except as requested by Tenant; (g) costs recoverable by Landlord on account of warranties or insurance, and (h) offsite management or other general overhead costs incurred by Landlord.

13.           Vendor Entry During Construction Period.  Notwithstanding anything to the contrary in the Lease or this Work Letter, Tenant may, prior to the Substantial Completion of the Tenant Improvements, and during and in conjunction with the construction of the Tenant Improvements, permit Tenant’s vendors to enter the Premises for the purpose of installing telephones, electronic communication or related equipment, security or audio/visual equipment, and furniture systems and equipment, provided that Tenant shall be solely responsible for any of such equipment, fixtures, furniture or material and for any loss or damage thereto from any cause whatsoever, excluding only the gross negligence or deliberate misconduct of Landlord or Landlord’s Contractors.  Such early access to the Premises and such installation shall be permitted only to the extent that Landlord determines that such early access and installation activities will not delay Landlord’s Contractor’s completion of the construction of the Tenant Improvements, provided that Landlord’s Contractor shall use reasonable good faith efforts to reasonably integrate the work to be completed by Tenant’s Vendors into Landlord’s Contractor’s scheduling and planning such that the Tenant Improvements and the work to be completed by Tenant’s Vendors will be completed in an efficient manner.  Further, subject to the foregoing, Landlord and Tenant shall cooperate in the scheduling of Tenant’s early access to the Premises and of Tenant’s installation activities in an attempt to maximize the benefits to Tenant of this Paragraph 13 without interfering with the completion of the construction of the Tenant Improvements.

14.           Addresses for Notices and Deliveries.  Notwithstanding the provisions of Section 23.13 of the Lease to the contrary, for the purposes of this Work Letter (i) notices, submittals and deliveries to Landlord shall be

7

made to Landlord’s Contractor and Landlord’s Representative at the addresses set forth below, (ii) notices, submittals and deliveries to Tenant shall be made to Tenant’s Representative at the address set forth below, and (iii) notices, submittals and deliveries to either pay may be made via facsimile transmissions with answerback confirmation at the respective facsimile numbers set forth below.  Facsimile transmissions received after 6:00 P.M. shall be deemed to have been given the following business day.

15.           Removal; Internal Stairway.  Landlord, simultaneously with Landlord’s final approval of the Working Drawings, shall notify Tenant (a “Removal Notice”) in writing, whether, in Landlord’s opinion, any of the alterations, additions or improvements described in the Working Drawings constitute an Extraordinary Fixture (as defined in Section 8.4 of the Lease) which Tenant must remove a the expiration or earlier termination of the term of the Lease.  Notwithstanding the foregoing, Tenant acknowledges that any internal stairway shall be considered an Extraordinary Fixture, and, regardless of whether Landlord delivers a Removal Notice in connection therewith, Landlord may elect to require Tenant to remove the internal stairway upon the expiration or termination of the Lease or at any time Tenant does not lease the entire fifth (5^th) floor of the Building together with that portion of the fourth (4^th) floor of the Building to which such internal stairwell connects, which election shall be made by written notice to Tenant, given at or prior to the expiration or earlier termination of the Lease.

29.9 Privilege Personal.  The privilege to bring dogs into the building is personal to Advent Software, Inc. and Affiliate Transferees, and is based on Advent Software, Inc.’s long experience in permitting its employees to bring dogs into the workplace under clearly established rules without incident.  This privilege shall not apply to subtenants or assignees of Advent Software, Inc. other than Affiliate Transferees.
