 PREMISES AND COMMON AREAS
 
 3.1 Demising Clause . Landlord hereby leases to Tenant, and Tenant hires from Landlord the Leased Premises, consisting of the approximate square footage listed in the Salient Lease Terms, which the parties agree shall be deemed the actual square footage.
 
 Temporary Premises . From and after the full execution of this Lease by Landlord and Tenant and ending thirty (30) days after the occurrence of the Commencement Date (the  Temporary Premises Expiration Date ), Landlord shall lease to Tenant, and Tenant shall lease from Landlord, approximately twenty-four thousand nine hundred seven (24,907) rentable square feet located on the fifth (5th) floor of the Building (the  Temporary Premises ) upon and subject to the terms of this Lease, except that Tenant shall not be required to pay Minimum Monthly Rent or Operating Costs, Insurance Costs or Taxes with respect to such Temporary Premises (provided, however, that Tenant shall pay to Landlord costs of janitorial services, separately-metered utilities and other services provided to Tenant). Tenant accepts the Temporary Premises in its as is condition and agrees that Landlord shall have no obligation to improve or otherwise alter the Temporary Premises. Any installation of cabling or wiring in the Temporary Premises by Tenant shall be performed by Tenant at Tenants sole cost and expense and in accordance with the terms of Article 12 below. On the Temporary Premises Expiration Date or such earlier date if this Lease is terminated, Tenant shall surrender the Temporary Premises to Landlord in accordance with the terms of Article 27 of this Lease. On or before the date that Tenant surrenders the Temporary Premises to Landlord, Tenant shall remove its cabling and wiring from the Temporary Premises and shall restore the Temporary Premises to substantially the same condition existing as of the date Tenant takes occupancy of the Temporary Premises, reasonable wear and tear, damage by casualty or condemnation excepted.
 
 3.3 Reservation . Landlord reserves the area beneath and above the Building as well as the exterior thereof together with the right to install, maintain, use, repair and replace pipes, ducts, conduits, wires, and structural elements leading through the Leased Premises serving other parts of the Building and the Common Areas of the Complex, so long as such items are concealed by walls, flooring or ceilings. Such reservation in no way affects the maintenance obligations imposed herein. Landlord may change the shape, size, location, number and extent of the improvements to any portion of the Building (excluding the Leased Premises) or the Common Areas of the Complex and/or the address of the Building without the consent of Tenant; provided, however, that Landlord shall not change the address of the Building unless required to do so by the City and County of Santa Clara or by applicable law, in which case Landlord shall notify Tenant of such anticipated change of address. Landlord shall use commercially reasonable efforts to minimize interference with the operation of Tenants business in the Leased Premises.
 
 
  3.4 Covenants, Conditions and Restrictions . The parties agree that this Lease is subject to the effect of (a) those certain covenants, conditions, restrictions, easements, mortgages or deeds of trust, ground leases, rights of way of record, and any other matters or documents of record listed on Exhibit H attached hereto, including, without limitation, the Reciprocal Easement Agreement referred to in the Salient Lease Terms; (b) any zoning laws of the city, county and state where the Complex is situated; and (c) general and special taxes not delinquent. Tenant agrees that as to its leasehold estate, Tenant and all persons in possession or holding under Tenant will conform to and will not violate the terms of any covenants, conditions or restrictions of record which may now or hereafter encumber the Building or the Complex (collectively, the  Restrictions ); provided, however, that Landlord shall not hereafter create, without the written consent of Tenant, any new Restrictions that materially and adversely affect Tenants rights under this Lease. This Lease is subordinate to the Restrictions and any amendments or modifications thereto.
 
 3.5  Common Areas . Landlord hereby grants to Tenant, for the benefit of Tenant and its employees, suppliers, shippers, customers and invitees, during the Term of this Lease, the non-exclusive right to use, in common with others entitled to such use, the Common Areas as they exist from time to time, subject to any rights, powers, and privileges reserved by Landlord under the terms hereof or under the terms of any rules and regulations or restrictions governing the use of the Building or the Complex. Under no circumstances shall the right herein granted to use the Common Areas be deemed to include the right to store any property, temporarily or permanently, in the Common Areas. Any such storage shall be permitted only by the prior written consent of Landlord or Landlords designated agent, which consent may be revoked at any time. In the event that any unauthorized storage shall occur then Landlord shall have the right, with reasonable prior notice, in addition to such other rights and remedies that it may have, to remove the property and charge the cost to Tenant, which cost shall be immediately payable upon demand by Landlord.
 
 (a)  Common AreasChanges . Landlord shall have the right, in Landlords sole discretion, from time to time:
 
 (1) Subject to the terms of Section 3.5(c) below, to make changes and reductions to the Common Areas, including, without limitation, changes in the location, size, shape and number of driveways, entrances, parking spaces, parking areas, loading and unloading areas, ingress, egress, direction of traffic, landscaped areas and walkways;
 
 (2)  To close temporarily any of the Common Areas for maintenance purposes so long as reasonable access to the Leased Premises remains available;
  
 (3)  To designate other land outside the boundaries of the Building to be a part of the Common Areas;
 
 
 (4)  To add additional improvements to the Common Areas;
 
 
 (5)  To use the Common Areas while engaged in making additional improvements, repairs or alterations to the Building or the Complex, or any portion thereof;
 
 (6)  To do and perform such other acts and make such other changes in, to or with respect to the Common Areas, the Building and the Complex as Landlord may, in the exercise of sound business judgment, deem to be appropriate.
 
 In exercising any of the foregoing rights, (i) Landlord shall not prevent Tenant from having reasonable access to the Leased Premises or the Parking Garage, and (ii) Landlord shall not take any action that will unreasonably and adversely affect Tenants parking rights hereunder.
 
 (b)  Common Area Maintenance. Landlord shall, in Landlords reasonable discretion, maintain the Common Areas (subject to reimbursement pursuant to this Lease), establish and enforce reasonable rules and regulations concerning such areas, close any of the Common Areas to whatever extent required in the opinion of Landlords counsel to prevent a dedication of any of the Common Areas or the accrual of any rights of any person or of the public to the Common Areas, close temporarily any of the Common Areas for maintenance purposes, and make changes to the Common Areas including, without limitation, changes in the location of driveways, corridors, entrances, exits, the designation of areas for the exclusive use of others, the direction of the flow of traffic or construction of additional buildings thereupon. Landlord may provide security for the Common Areas, but is not obligated to do so. Under no circumstances shall Landlord be liable or responsible for any acts or omissions of any party providing any services to the Common Areas, the Building or other improvements, including, without limitation, any security service, notwithstanding anything to the contrary contained in this Lease.

 Parking. Provided that Tenant is not in Default of any term or provision of this Lease or has not vacated the Leased Premises, Tenant is allocated and shall have the non-exclusive right on an unassigned and unreserved basis to use not more than the number of parking spaces specified in Section 1.18 hereof for use by Tenant and its directors, officers, employees, contractors, suppliers, agents, subtenants, licensees, occupants and invitees ( Tenants Parties ), the location of which may be designated from time to time by Landlord (the  Parking Spaces ). At no time, may Tenant or any of Tenants Parties use more than the number of Parking Spaces specified above.
 
 Operation. The Parking Spaces allocated to Tenant are located in the Parking Garage. The Parking Garage is located on land that is owned by the owner of the adjacent building located at 3975 Freedom Circle Drive, Santa Clara, California ( Mission Tower One Building ). The Parking Garage is subject to the Reciprocal Easement Agreement and is operated and maintained by the owner of the Mission Tower One Building. The Parking Garage provides parking for the Building and the Mission Tower One Building. Landlord hereby covenants with Tenant that Landlord shall not exercise any rights available to Landlord under the Reciprocal Easement Agreement that would diminish the amount of Parking Spaces or otherwise restrict the parking rights of Tenant set forth herein. Additionally, Landlord covenants that Landlord shall not voluntarily terminate or modify, or consent to the termination or modification of the Reciprocal Easement Agreement for any reason without Tenants prior written consent, unless such modification would not adversely affect Tenants right to use the Parking Spaces hereunder. In the event that Landlord defaults on its payment obligations under the Reciprocal Easement Agreement, Landlord shall forward any default notice Landlord receives from the owner of the Mission Tower One Building to Tenant promptly upon its receipt of the same. Landlord shall immediately deliver to Tenant copies of all default notices pertaining to the Parking Garage that Landlord sends to or receives from the owner of the Mission Tower One Building. In the event of such default by Landlord under the Reciprocal Easement Agreement and provided that Landlord has not commenced to cure such default within five (5) Business Days or thereafter fails to diligently cure such default, then Tenant shall have the right, but not the obligation, to cure such default with the owner of the Mission Tower One Building on Landlords behalf; provided, however, that Tenant shall not be permitted to make payments or otherwise cure such default for as long as Landlord is in good faith disputing or contesting such default. If Tenant elects to cure such default, then Landlord shall reimburse Tenant for the reasonable costs expended by Tenant within five (5) Business Days of receipt of written request from Tenant.
 
 
  (2) General Procedures. The unreserved parking spaces hereunder may be provided on an unreserved valet parking basis. The Parking Spaces initially will not be separately identified, however Landlord reserves the right in its sole and absolute discretion to separately identify by signs or other markings the area where Tenants Parking Spaces will be located. Landlord or the owner of the Mission Tower One Building may arrange for the Parking Garage to be operated by an independent contractor. Tenant acknowledges that Landlord shall have no liability for claims arising through acts or omissions of such operator. Landlord shall have no obligation to monitor the use of such parking facility, nor shall Landlord be responsible for any loss or damage to any vehicle or other property or for any injury to any person. Said Parking Spaces shall be used only for parking of automobiles no larger than full size passenger automobiles, sport utility vehicles or pickup trucks. Tenant shall comply with all rules and regulations which may be adopted by Landlord or the owner of Mission Tower One Building or the operator of the Parking Garage from time to time.
 
 (3)  Usage. Tenant shall not at any time use more parking spaces than the number so allocated to Tenant or park its vehicles or the vehicles of others in any portion of the Complex designated as an exclusive parking area. Tenant shall not have the exclusive right to use any specific parking space. All trucks and delivery vehicles shall be (i) parked in area designated for such vehicles, (ii) loaded and unloaded in a manner which does not interfere with the businesses of other occupants of the Complex, and (iii) permitted to remain on the Complex only so long as is reasonably necessary to complete loading and unloading. In the event Landlord elects or is required by any law to limit or control parking in the Complex, whether by validation of parking tickets or any other method of assessment, Tenant agrees to participate in such validation or assessment program under such reasonable rules and regulations as are from time to time established by Landlord.
 
 (4)  Identification. If Landlord so requests, Tenant shall furnish Landlord with a list of its employees vehicle license numbers within fifteen (15) days after taking possession of the Leased Premises and thereafter shall notify Landlord of any changes within five (5) days after written request by Landlord. Landlord also reserves the right to implement a system requiring that all employees of Tenant attach a parking sticker or parking permit to its vehicle, such system to be implemented at Landlords sole cost and expense.
 
 (5)  Remedies. Tenant acknowledges and agrees that a breach of the parking provisions by Tenant or any of Tenants Parties may seriously interfere with Landlords operation of the Complex and with the rights or occupancy by other tenants of the Complex and in the Mission Tower One Building. Accordingly, Landlord may suffer damages that are not readily ascertainable. Therefore, if Tenant or any of Tenants Parties use more than the number of allocated Parking Spaces, or park other than as so designated by Landlord for the Parking Spaces, or otherwise fail to comply with any of the foregoing provisions after Landlord delivers written notice to Tenant of such failure and Tenant fails to cure the same within five (5) hours after receipt of such notice, then Landlord, in addition to any other rights or remedies available at law or in equity or under this Lease, may charge Tenant, as liquidated damages, Twenty-Five Dollars ($25.00) per day for the first such violation and Fifty Dollars ($50.00) per day for each subsequent violation, and Tenant shall pay such charge within ten (10) days after written request by Landlord. Each vehicle parked in violation of the foregoing provisions shall be deemed a separate violation. In addition, if Tenant fails to cure any such violation after receiving written notice from Landlord, Landlord may immobilize and/or tow from the Complex any vehicle parked in violation hereof, and/or attach violation stickers or notices to such vehicle. The cost to remove any such vehicle shall be paid by Tenant within ten (10) days after written request by Landlord.
 
 
  (6) Termination. If at any time during the Term there is a temporary material reduction in the number of Parking Spaces allocated to Tenant in the Parking Garage, and provided that such reduction is not caused by the acts of Tenant or Tenants agents, advisors, employees, partners, shareholders, directors, invitees and independent contractors (collectively, Tenants Agents), Landlord shall use commercially reasonable efforts to provide Tenant with alternative parking spaces located within a one (1) mile radius of the Complex, in which case Landlord shall provide Tenant with transportation from such alternative parking to the Complex (the method and frequency of which shall be determined by Landlord, in Landlords reasonable discretion), at Landlords sole cost and expense. As used in the foregoing sentence, (a) material shall mean the loss of use by Tenant of at least fifty (50) Parking Spaces in the Parking Garage, and (b) temporary shall mean no more than one hundred twenty (120) days. If Landlord fails to provide Tenant with such alternative parking within thirty (30) days following Tenants request therefor, Tenant, as its sole and exclusive remedy, shall have the right to terminate this Lease, upon ten (10) days prior written notice to Landlord. Notwithstanding the foregoing, if any material reduction in the number of Parking Spaces occurs, which is beyond a temporary reduction and is not caused by Tenant, then Tenant shall have the right to terminate this Lease.

 4.1 Commencement Date . The Term of this Lease shall commence on the Commencement Date and shall be for the term specified in Section 1.10 hereof (which includes any partial month at the commencement of the Term if the Term commences other than on the first day of the calendar month).
 
 4.2 Acknowledgment of Commencement . After delivery of the Initial Premises and the Secondary Premises, respectively, to Tenant, Tenant shall execute a written acknowledgment of the date of commencement in the form attached hereto as Exhibit D , and by this reference it shall be incorporated herein.

 Pre-Term Possession . If the Leased Premises are to be constructed or remodeled by Landlord, Landlord may notify Tenant when the Leased Premises are ready for Tenants fixturing or Tenants work, which may be prior to Substantial Completion of the Leased Premises by Landlord. Tenant may thereupon enter the Leased Premises for such purposes at its own risk, to make such improvements as Tenant shall have the right to make, to install fixtures, supplies, inventory and other property. Such entry by Tenant prior to the Substantial Completion of the Leased Premises by Landlord shall be referred to herein as  Pre-Term Possession . Tenant agrees that it shall not in any way interfere with the progress of Landlords work by such entry. Should such entry prove an impediment to the progress of Landlords work, in Landlords reasonable judgment, Landlord may demand that Tenant forthwith vacate the Leased Premises until such time as Landlords work is complete, and Tenant shall immediately comply with this demand. During the course of any Pre-Term Possession, all terms and conditions of this Lease, except for Tenants obligation to pay Minimum Monthly Rent, Operating Costs, Insurance Costs and Taxes, shall apply, particularly with reference to indemnity by Tenant of Landlord under Sections 10.4 and 14.4.

 4.4 Delay .
  
 (a) If Landlord, for any reason whatsoever, cannot deliver possession of the Leased Premises to Tenant with the Tenant Improvements Substantially Completed at the Estimated Commencement Date, this Lease shall not be void or voidable, nor shall Landlord be liable for any loss or damage resulting therefrom, but in that event, there shall be no accrual of Rent for the period between the Estimated Commencement Date and the Commencement Date, except if the delay is due to a Tenant Delay (as defined in Exhibit C attached hereto).
 
 
 (b)  Notwithstanding anything herein to the contrary, if the Commencement Date has not occurred on or before the Outside Completion Date (defined below), Tenant shall be entitled to a rent abatement following the Commencement Date of Nine Hundred Thirty-Two Dollars ($932.00) for every day in the period beginning on the Outside Completion Date and ending on the Commencement Date. The  Outside Completion Date  shall mean January 1, 2005. Landlord and Tenant acknowledge and agree that: (i) the determination of the Commencement Date shall take into consideration the effect of any Tenant Delays by Tenant; and (ii) the Outside Completion Date shall be postponed by the number of days the Commencement Date is delayed due to events of Force Majeure. Notwithstanding anything herein to the contrary, if the Commencement Date has not occurred on or before one hundred eighty (180) days following the Outside Completion Date (the  Outside Termination Date ), Tenant may, as its sole remedy, terminate this Lease by giving Landlord written notice of termination within thirty (30) days following the Outside Termination Date.
 
 4.5 Failure to Take Possession. Tenants inability or failure to take possession of the Leased Premises when delivery is tendered by Landlord shall not delay the Commencement Date of this Lease or Tenants obligation to pay Rent. Tenant acknowledges that Landlord shall incur significant expenses upon the execution of this Lease, even if Tenant never takes possession of the Leased Premises, including, without limitation, brokerage commissions and fees, legal or other professional fees, the costs of space planning and the costs of construction of Tenant Improvements in the Leased Premises. Tenant acknowledges that all of said expenses, in addition to all other expenses incurred and damages suffered by Landlord, shall be included in measuring Landlords damages should Tenant breach the terms of this Lease.

 ARTICLE 6
 ADDITIONAL RENT
 
 Personal Property, Gross Receipts, Leasing Taxes . This Section is intended to deal with impositions or taxes directly attributed to Tenant or this transaction, as distinct from taxes attributable to the Building or the Common Areas of the Complex which are to be allocated among various tenants and others. Tenant shall pay before delinquency any and all taxes, assessments, license fees and public charges levied, assessed or imposed against Tenant or Tenants estate in this Lease or the property of Tenant situated within the Leased Premises which become due during the Term. On demand by Landlord, Tenant shall furnish Landlord with satisfactory evidence of these payments. If such taxes are included in the bill for the Real Estate Taxes for the Building or the Complex, then Tenant shall pay to Landlord as additional rent the amount of such taxes within ten (10) days after demand from Landlord.
 
 
 6.2  Operating Costs, Taxes and Insurance .
 
 
 (a) Adjustment. Operating Costs, Insurance Costs and Taxes for any Lease Year shall be calculated on the basis of the greater of (i) actual Operating Costs, Taxes and Insurance Costs; or (ii) what Operating Costs, Insurance Costs and Taxes would have been if the Building were at least one hundred percent (100%) occupied and operational for the whole of such Lease Year to take into consideration any such costs that may fluctuate with occupancy. Operating Costs, Insurance Costs and Taxes shall be calculated separately for each such category of costs.
 
 (b)  Partial Year. If any Lease Year of less than twelve (12) months is included within the Term, the amount payable by Tenant for such period shall be prorated on a per diem basis (utilizing a thirty (30) day month, three hundred sixty (360) day year).
 
 6.3  Method of Payment . Any additional Rent payable by Tenant under Sections 6.1 and 6.2 hereof shall be paid as follows, unless otherwise provided:
 
 (a) Tenant Payment. Beginning on the first day of the thirteenth (13th) month of the Initial Term for the Initial Premises and thereafter, Tenant shall pay to Landlord Tenants Proportionate Share of Operating Costs, Insurance Costs and Taxes, as additional Rent as hereinafter provided; provided, however, that with respect to the Property Management Fee, Tenant shall pay the Property Management Fee (as that term is defined in Article 2, subclause (7)) in its entirety (i.e., 100%) and not simply Tenants Proportionate Share of the same. Tenant shall pay to Landlord monthly in advance with its payment of Minimum Monthly Rent, one-twelfth (l/12th) of the amount of such additional Rent as estimated by Landlord in advance, in good faith, to be due from Tenant. If at any time during the course of the fiscal year, Landlord determines that Operating Costs, Insurance Costs and/or Taxes are projected to vary from the then estimated costs for such items by more than five percent (5%) or there is a special or non-reoccurring charge under the Reciprocal Easement Agreement, Landlord may, by delivering thirty (30) days prior written notice to Tenant, revise the estimated Operating Costs, Insurance Costs and/or Taxes for the balance of such fiscal year, and Tenants monthly installments for the remainder of such year shall be adjusted so that by the end of such fiscal year Tenant will have paid to Landlord Tenants Proportionate Share of the such revised expenses for such year.
 
 (b)  Annual Reconciliation. Annually, as soon as is reasonably possible after the expiration of each Lease Year, Landlord shall prepare in good faith and deliver to Tenant a comparative statement, which statement shall be conclusive between the parties hereto, setting forth (1) the Operating Costs, Taxes and Insurance Costs for such Lease Year, and (2) the amount of additional Rent as determined in accordance with the provisions of this Article 6. Landlord shall use reasonable efforts to furnish such comparative statement on or before June 1 of the calendar year immediately following the calendar year to which the statement applies.
  
  
 (c)  Adjustment. If the aggregate amount of such estimated additional Rent payments made by Tenant in any Lease Year should be less than the additional Rent due for such year, then Tenant shall pay to Landlord as additional Rent within ten (10) days following demand the amount of such deficiency. If the aggregate amount of such additional Rent payments made by Tenant in any Lease Year of the Term should be greater than the additional Rent due for such year, then the amount of such excess will be applied by Landlord to the next succeeding installments of such additional Rent due hereunder; and if there is any such excess for the last year of the Term, the amount thereof will be refunded by Landlord to Tenant within sixty (60) days of the last day of the Term.
 
 (d) Audit. Within ninety (90) days after receiving Landlords statement of Operating Costs Tenant may, upon advance written notice to Landlord and during reasonable business hours, cause an audit of Landlords books and records to determine the accuracy of Landlords Operating Costs and other charges under this Lease. Landlord shall make all pertinent records available for inspection that are reasonably necessary for Tenant to conduct its review. If any records are maintained at a location other than the office of the Building, Tenant may either inspect the records at such other location or pay for the reasonable cost of copying and shipping the records. If Tenant retains an agent to review Landlords records, the agent shall be with a licensed CPA firm. Within sixty (60) days after the records are made available to Tenant, Tenant shall have the right to give Landlord written notice (an  Objection Notice ) stating in reasonable detail any objection to Landlords statement of Operating Costs for that year. If Tenant provides Landlord with a timely Objection Notice, Landlord and Tenant shall work together in good faith to resolve any issues raised in Tenants Objection Notice. If Tenant fails to provide Landlord with a timely Objection Notice, Landlords statement of Operating Costs shall be deemed final and binding, and Tenant shall have no further right to audit or object to such statement. If Tenants audit reveals that the actual direct expenses for any given year were less than the amount that Tenant paid for Operating Costs and other charges for any such year, then Landlord shall pay to Tenant the excess. If such audit reveals that the actual direct expenses for any given year were more than the amount that Tenant paid for Operating Costs and other charges for any such year, then Tenant shall pay to Landlord the excess.
 
 
 ARTICLE 7
 ACCORD AND SATISFACTION
  7.1 Acceptance of Payment . No payment by Tenant or receipt by Landlord of a lesser amount of Minimum Monthly Rent or any other sum due hereunder, shall be deemed to be other than on account of the earliest due rent or payment, nor shall any endorsement or statement on any check or any letter accompanying any such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlords right to recover the balance of such rent or payment or pursue any other remedy available in this Lease, at law or in equity. Landlord may accept any partial payment from Tenant without invalidation of any contractual notice required to be given herein (to the extent such contractual notice is required) and without invalidation of any notice required to be given pursuant to California Code of Civil Procedure Section 1161 et seq. , or of any successor statute thereto.
 
 ARTICLE 8
 SECURITY DEPOSIT
 
 Payment on Lease Execution . Tenant shall pay Landlord , within seven (7) Business Days following the execution hereof the sum specified in the Salient Lease Terms as a Security Deposit. This sum is designated as a Security Deposit and shall remain the sole and separate property of Landlord until actually repaid to Tenant, said sum not being earned by Tenant until all conditions precedent for its payment to Tenant have been fulfilled. As this sum both in equity and at law is Landlords separate property, Landlord shall not be required to (1) keep said deposit separate from his general accounts, or (2) pay interest, or other increment for its use. If Tenant fails to pay Rent or other charges when due hereunder beyond applicable notice and cure periods, or otherwise Defaults with respect to any provision of this Lease, including and not limited to Tenants obligation to restore or clean the Leased Premises following vacation thereof in accordance with Section 27.2 below beyond applicable notice and cure periods, Landlord may, without prejudice to any other remedy, use all or a portion of the Security Deposit (i.e., draw on the Letter of Credit) to satisfy past due Rent or to cure any uncured Default by Tenant or to compensate Landlord for its damages resulting therefrom , as permitted by applicable law . Landlord may retain such portion of the Security Deposit as it reasonably deems necessary to restore or clean the Leased Premises following vacation by Tenant. The Security Deposit is not to be characterized as rent until and unless so applied in respect of a Default by Tenant.
 
 
  8.2 Letter of Credit . The Security Deposit may be in the form of an irrevocable letter of credit (the  Letter of Credit ), which Letter of Credit shall: (a) be in the amount of Four Million Dollars ($4,000,000.00); (b) be issued in substantially the form attached hereto as Exhibit F ; (c) name COR US Bank, N.A., a national banking association, as its beneficiary; and (d) be drawn on an FDIC insured financial institution reasonably satisfactory to Landlord. The Letter of Credit (and any renewals or replacements thereof) shall be for a term of not less than one (1) year. Tenant agrees that it shall from time to time, as necessary, whether as a result of a draw on the Letter of Credit by Landlord pursuant to the terms hereof or as a result of the expiration of the Letter of Credit then in effect, or in the event the issuer of the Letter of Credit refuses to transfer the Letter of Credit as instructed by Landlord (subject to the limitations on transfer as set forth in the Letter of Credit), renew or replace the original and any subsequent Letter of Credit so that a Letter of Credit, in the amount required hereunder, is in effect until a date which is at least sixty (60) days after the Termination Date of the Lease. If Tenant fails to furnish such renewal or replacement at least thirty (30) days prior to the stated expiration date of the Letter of Credit then held by Landlord, or within thirty (30) days after written notice from Landlord that any other event that obligates Tenant to replace the Letter of Credit (such as the issuers refusal to transfer the existing Letter of Credit) has arisen, Landlord may draw upon such Letter of Credit and hold the proceeds thereof (and such proceeds need not be segregated) as a Security Deposit pursuant to the terms of this Article 8. Any renewal or replacement of the original or any subsequent Letter of Credit shall meet the requirements for the original Letter of Credit as set forth above, except that such replacement or renewal shall be issued by an FDIC insured financial institution reasonably satisfactory to Landlord at the time of the issuance thereof.
 
 
 ( x) Reduction in the Amount of the Security Deposit . Subject to the terms of Article 8, and provided that, as of the effective date of any reduction of the Security Deposit (as set forth below) (each, a  Potential Reduction Date ), (a) Tenant has timely paid all Rent due under this Lease, and (b) Tenant is not then in material non-monetary Default under any provision of this Lease and failed to cure such Default, then Tenant shall have the right to reduce the amount of the Security Deposit to the following amounts at the following times: (i) Three Million Two Hundred Thousand Dollars ($3,200,000.00) effective as of the first day of the second Lease Year; (ii) Two Million Four Hundred Thousand Dollars ($2,400,000.00) effective as of the first day of the third Lease Year; (iii) One Million Six Hundred Thousand Dollars ($1,600,000.00) effective as of the fourth Lease Year; and (iv) Five Hundred Forty-Two Thousand Four Hundred Sixty-Nine Dollars ($542,469.00) effective as of the fifth Lease Year. If Tenant is not entitled to reduce the Security Deposit as of a particular reduction effective date as set forth above due to Tenants failure to satisfy the conditions in clauses (a) and (b) of the first sentence of this Section 8.2(x), then Tenant shall forego the ability to reduce the Security Deposit for that particular Lease Year to which it is not entitled for the remainder of the Term; provided, however, that once Tenant cures any such default, Tenant shall be entitled to such foregone reduction at the time that Tenant cures such default.
 
 
 8.3  Restoration of Security Deposit . If Landlord elects to use or apply all or any portion of the Security Deposit as provided in Section 8.1, Tenant shall within twenty (20) days after written demand therefor restore the amount of the Security Deposit to its then required amount by providing Landlord with either cash in such amount if the Security Deposit is cash or an amendment to the Letter of Credit evidencing that the amount available under the Letter of Credit has been restored to its then required amount if the Security Deposit is in the form of a Letter of Credit. Landlord shall hold any such restoration of the Security Deposit as part of the Security Deposit in accordance with the terms of Section 8.1 above.
 
 8.4  Return of Security Deposit . The Letter of Credit or any balance thereof not drawn upon (or if the Security Deposit is cash, then the remaining cash) shall be returned to Tenant by Landlord within thirty (30) days of the expiration or earlier termination of this Lease after first deducting those amounts, if any, that Landlord is allowed to deduct in accordance with this Lease. Landlord shall provide Tenant with a written explanation and itemization of any deductions taken from the Security Deposit within such thirty (30) day period.

Notwithstanding the foregoing, Landlord shall have no liability for any damage caused by the installation of such heavy equipment or safes.
 
 
 9.3  Machinery .

Landlord, at its sole cost and expense, shall be responsible for correcting any violations of governmental laws, ordinances, regulations or mandates, including, without limitation, Title III of the ADA, with respect to the Leased Premises, provided that Landlords obligation with respect to the Leased Premises shall be limited to violations that arise out of the initial Tenant Improvements performed by Landlord and/or the condition of the Leased Premises prior to the commencement of the Term of this Lease as to the Initial Premises or the Secondary Premises, as the case may be; provided, however, that Landlord shall not be responsible for non-compliance that results thereafter from installation of any furniture, equipment and other personal property by Tenant.

Tenants obligation to comply with and observe such requirements, ordinances, statutes and regulations shall apply regardless of whether such requirements, ordinances, statutes and regulations regulate or relate to Tenants particular use of the Leased Premises or regulate or relate to the use of premises in general, and regardless of the cost thereof. The judgment of any court of competent jurisdiction, or the admission of Tenant in any action or proceeding against Tenant, whether Landlord be a party thereto or not, that any such requirement, ordinance, statute or regulation pertaining to the Leased Premises has been violated, shall be conclusive of that fact as between Landlord and Tenant. Notwithstanding the foregoing, Tenant shall have no responsibility or liability for (a) the remediation of Hazardous Materials present on or under the Leased Premises, the Building or the Complex, except to the extent such presence is caused or recklessly exacerbated by the acts or omissions of Tenant or Tenants, employees, agents, licensees or contractors (and, in the case of exacerbation of an existing condition, Tenant shall be liable only to the extent of such exacerbation), (b) making structural improvements or alterations to the Leased Premises in order to comply with changes in laws (including, without limitation, the ADA) unless such improvements or alterations are necessitated by Tenants alterations or particular use of the Leased Premises, or (c) any non-compliance of the Building with any laws that are in existence as of the Commencement Date (except to the extent Tenants actions or particular use of the Leased Premises causes or contributes to such non-compliance). For purposes of this Section 10.1, Landlords actual knowledge shall be deemed to refer to the actual (as opposed to constructive, implied or imputed) knowledge of John Moe, without any duty of inquiry or investigation.
 
 
 10.2  Condition of Leased Premises . Subject to Landlords work and to the completion of any punch list items, as referred to in Exhibit C to this Lease, Tenant hereby accepts the Leased Premises in the condition existing as of the date of this Lease, subject to all applicable zoning, municipal, county and state laws, ordinances, rules, regulations, orders, restrictions of record, and requirements in effect during the Term or any part of the Term hereof regulating the Leased Premises, and without representation, warranty or covenant by Landlord, express or implied, as to the condition, habitability or safety of the Leased Premises, the suitability or fitness thereof for their intended purposes, or any other matter.

Landlords approval of any space plan, floor plan, construction plans, specifications, or other drawings or materials regarding the construction of the Tenant Improvements or any alterations shall not be deemed or construed as consent by Landlord under this paragraph to Tenants use of such excess electrical current as provided above.

Tenant acknowledges that any one or more such services may be suspended or reduced by reason of repairs, alterations or improvements necessary to be made, by strikes or accidents, by any cause beyond the reasonable control of Landlord, or by orders or regulations of any federal, state, county or municipal authority. Any such interruption or suspension of services shall not be deemed an eviction or disturbance of Tenants use and possession of the Leased Premises or any part thereof, nor render Landlord liable to Tenant for damages by abatement of Rent or otherwise, nor relieve Tenant of performance of Tenants obligations under this Lease. Landlord shall use commercially reasonable efforts to notify Tenant of any anticipated interruption or suspension of services and to restore any service interruption to the Leased Premises.

Such bond must be posted within ten (10) Business Days following notice from Landlord. In addition, Landlord may require Tenant to pay Landlords reasonable attorneys fees and costs in participating in any action to foreclose such lien if Landlord shall decide it is to its best interest to do so.

 ARTICLE 14
 INDEMNIFICATION, WAIVER OF CLAIMS AND SUBROGATION
 
 14.1  Intent and Purpose . This Article 14 is written and agreed to in respect of the intent of the parties to assign the risk of loss, whether resulting from negligence of the parties or otherwise, to the party who is obligated hereunder to cover the risk of such loss with insurance. Thus, the indemnity and waiver of claims provisions of this Lease have as their object, so long as such object is not in violation of public policy, the assignment of risk for a particular casualty to the party carrying the insurance for such risk, without respect to the causation thereof.
 
 
  14.2 Waiver of Subrogation . Landlord and Tenant release each other, and their respective authorized representatives, from any claims for damage to the Leased Premises, the Building, the Complex and other improvements in which the Leased Premises are located, and to the furniture, fixtures, and other business personal property, Tenants improvements and alterations of either Landlord or Tenant, in or on the Leased Premises, the Building and the Complex and other improvements in which the Leased Premises are located, including loss of income, that are caused by or result from risks insured or required under the terms of this Lease to be insured against under any property insurance policies carried or to be carried by either of the parties.
 
 14.3 Form of Policy . Each party shall cause each such insurance policy obtained by it to provide that the insurance company waives all rights of recovery by way of subrogation against either party in connection with any damage covered by such policy. Neither party shall be liable to the other for any damage caused by any peril included within the classification All Risk or Special Causes of Loss which is insured against under any property insurance policy carried or required to be carried under the terms of this Lease.
 
 Indemnity . Tenant, as a material part of the consideration to be rendered to Landlord, shall indemnify, defend, protect and hold harmless Landlord against all actions, claims, demands, damages, liabilities, losses, penalties, or expenses of any kind which may be brought or imposed upon Landlord or which Landlord may pay or incur by reason of (a) injury or death to person or damage to property, from whatever cause, including, without limitation, the negligence of the parties hereto, all or in any way connected with the condition or use of the Leased Premises, or the improvements or personal property therein or thereon, including, without limitation, any liability or injury to the person or property of Tenant, its agents, officers, employees or invitees, and (b) any injury or death to any person or damage to property caused by the negligence of Tenant or any of its officers, partners, employees or agents anywhere in the Complex. Nothing contained herein shall obligate Tenant to indemnify Landlord against the gross negligence or willful acts of Landlord or its officers, employees or agents or Landlords breach of this Lease. Landlord agrees to indemnify Tenant for all actions, claims, demands, liabilities, losses, costs and expenses arising out of the gross negligence or willful misconduct of Landlord or its officers, employees and agents anywhere in the Complex.
 
 Defense of Claims . In the event any action, suit or proceeding is brought against Landlord by reason of any such occurrence, Tenant, upon Landlords request, will at Tenants expense resist and defend such action, suit or proceeding, or cause the same to be resisted and defended by counsel designated either by Tenant or by the insurer whose policy covers the occurrence. Landlord agrees that it shall not enter into any settlement with respect to any claim covered by the indemnity set forth in this Article 14 or any other Section of this Lease without Tenants prior written consent, unless (i) Landlord believes in its good faith judgment that its exposure or liability with respect to such claim is likely to be substantially higher than the amount for which the claim is proposed to be settled, and (ii) Landlord has determined, in its reasonable discretion, that Tenant may not, at the time such claim is likely to be resolved (absent such settlement), have the financial wherewithal to perform such indemnity. If, based upon the foregoing, Landlord agrees not to enter into a settlement of a particular claim, then Tenant shall, at Landlords request, execute a reaffirmation acknowledging that, as between Tenant and Landlord, the indemnity provided in this Article 14 shall cover the applicable claim. If Tenant fails or refuses to execute and deliver such reaffirmation to Landlord promptly after Landlords request therefor, then notwithstanding anything in this Section 14.5 to the contrary, Landlord shall have the right to settle the applicable claim on terms acceptable to Landlord. If Landlord settles or compromises a claim without Tenants prior written consent and the conditions set forth in (i) and (ii) do not apply, then Tenant shall not be obligated to provide indemnification for the particular claim that is the subject of the claim or compromise under this Article 14 or other applicable Section of this Lease. If Landlord or any other indemnified party obtains recovery from a third party of any of the amounts that Tenant has paid to them pursuant to the indemnity set forth in this Article 14 or such other Section of the Lease, then Landlord or such other indemnified party, as applicable, shall promptly pay to Tenant the amount of such recovery up to the amount that Tenant previously paid. The obligations of Tenant and Landlord under this Section arising by reason of any occurrence taking place during the Term shall survive any termination of this Lease.
 
 14.6  Waiver of Claims . Tenant, as a material part of the consideration to be rendered to Landlord, hereby waives all claims against Landlord for damages or injury, as described below, from any cause arising at any time, including breach of the provisions of this Lease and the negligence of the parties hereto except to the extent such damages or injury are caused by the gross negligence or willful actions of Landlord, its agents, officers and employees:
 
 (a) damages to goods, wares, merchandise and loss of business in, upon or about the Leased Premises and injury to Tenant, its agents, employees, invitees or third persons, in, upon or about the Leased Premises, the Building or the Complex; and

 14.7 References . Wherever in this Article the term Landlord or Tenant is used and such party is to receive the benefit of a provision contained in this Article, such term shall refer not only to that party but also to its shareholders, officers, directors, employees, partners, members, managers, mortgagees and agents.

Subject to the other provisions of this Lease imposing obligations in this respect upon Tenant, Landlord shall repair, replace and maintain the external and Structural parts of the Building, the Building Systems, and the Common Areas of the Complex, including, without limitation, janitor and equipment closets and shafts within the Leased Premises designated by Landlord for use by it in connection with the operation and maintenance of the Complex, and all Common Areas.

Upon reasonable prior written notice to Tenant, Landlord may enter and view the state of repair and Tenant will repair in a good and workmanlike manner according to notice in writing.
  
 18.4  Cleaning . Tenant agrees at the end of each Business Day to leave the Leased Premises in a reasonably clean condition for the purpose of the performance of Landlords cleaning services referred to herein; provided, however, that the foregoing obligation shall not apply if Tenant elects to separately arrange for its own cleaning services pursuant to Section 11.6 above.

 ARTICLE 19
 DESTRUCTION
 
 Rights of Termination . In the event the Leased Premises or the Parking Garage suffers (a) an uninsured property loss (as hereinafter defined) or (b) a property loss which Landlord reasonably determines cannot be repaired within one hundred eighty (180) days from the date of destruction under the laws and regulations of state, federal, county or municipal authorities, or other authorities with jurisdiction, either party shall have the right to terminate this Lease by giving written notice to the other of such election within twenty (20) days of receipt of written notice from Landlord to Tenant that the damage from the casualty was an uninsured property loss or that time to restore will exceed such one hundred eighty (180) day period. Notwithstanding the foregoing, (A) Tenant shall not have the right to terminate this Lease if (i) the Leased Premises or the Parking Garage suffers an uninsured property loss that Landlord elects, at its sole cost and expense (it being agreed that Landlord shall not be permitted to pass through such costs to Tenant as Operating Costs), to repair, or (ii) if the fire or casualty was caused by the negligence or intentional misconduct of Tenant or any of Tenants transferees, agents, employees, contractors or licensees; and (B) Landlord shall not have the right to terminate this Lease if (x)  the Leased Premises suffers an uninsured property loss that Tenant elects, at its sole cost and expense, to repair; provided, however, that such repair of the Leased Premises shall be performed by either Landlord or Tenant, at Landlords sole election, or (y) the Parking Garage suffers an uninsured property loss and Tenant elects to pay the cost of repair, in which case Landlord shall use commercially reasonable efforts to cause the Parking Garage to be repaired by the Parcel 1 Owner (as defined in the Reciprocal Easement Agreement), in accordance with the terms of the Reciprocal Easement Agreement; provided, however, that Landlord shall not be liable to Tenant for any failure of the Parcel 1 Owner to repair the Parking Garage in accordance with the terms thereof. For purposes of this Lease, the term  uninsured property loss  shall mean any loss arising from a peril not covered by the standard form of All Risk or Special Causes of Loss property insurance policy and that materially impairs Tenants ability to use the Leased Premises or the Parking Garage for the purposes described in this Lease.
 
 
 19.2  Repairs . In the event of a property loss where this Lease is not terminated under the terms of Section 19.1 above or Sections 19.5 or 19.6 below, then this Lease shall continue in full force and effect and Landlord shall forthwith undertake to make such repairs to reconstitute the Leased Premises to as near the condition as existed prior to the property loss as possible. Such partial destruction shall in no way annul or void this Lease except that Tenant shall be entitled to a proportionate reduction of Minimum Monthly Rent following the property loss and until the time the Leased Premises are restored. Such reduction shall be based on the ratio that the square footage of the damaged portion of the Leased Premises bears to the total square footage of the Leased Premises. So long as Tenant conducts its business in the Leased Premises, there shall be no abatement until the parties agree on the amount thereof. If the parties cannot agree within forty-five (45) days of the property loss, the matter shall be submitted to arbitration under the rules of the American Arbitration Association. Upon the resolution of the dispute, the settlement shall be retroactive and Landlord shall within ten (10) days thereafter refund to Tenant any sums due in respect of the reduced rental from the date of the property loss. Landlords obligations to restore shall in no way include any of Tenants property or any construction originally performed by Tenant or subsequently undertaken by Tenant, but shall include that property constructed by Landlord pursuant to the terms of the Work Letter prior to commencement of the Initial Term for the Initial Premises hereof.
 
 
 19.3  Repair Costs . The cost of any repairs to be made by Landlord, pursuant to Section 19.2 of this Lease, shall be paid by Landlord utilizing available insurance proceeds. Tenant shall reimburse Landlord upon completion of the repairs for any deductible for which no insurance proceeds will be obtained under Landlords insurance policy, or if other premises are also repaired, a pro rata share based on total costs of repair equitably apportioned to the Leased Premises. Tenant shall, however, not be responsible to pay any deductible or its share of any deductible to the extent that Tenants payment would be in excess of Ten Thousand Dollars ($10,000.00) if Tenants consent has not been received by Landlord.
 
 
 19.4  Waiver . Tenant hereby waives all statutory or common law rights of termination in respect to any partial destruction or property loss which Landlord is obligated to repair or may elect to repair under the terms of this Article.
 
 
 19.5  Landlords Election . In the event that the Building is destroyed to the extent of not less than thirty-three and one-third percent (33?%) of the replacement cost thereof, Landlord may elect to terminate this Lease, whether the Leased Premises be injured or not, in the same manner as in Section 19.1 above. In all events, a total destruction of the Complex or the Building shall terminate this Lease.
 
 19.6  Damage Near End of Term . If at any time during the last twelve (12) months of the Term of this Lease there is, in Landlords reasonable opinion, substantial damage to the Leased Premises or the Building, whether or not such casualty is covered in whole or in part by insurance, Landlord may at Landlords option cancel and terminate this Lease as of the date of occurrence of such damage by giving written notice to Tenant of Landlords election to do so within thirty (30) days after the date of occurrence of such damage and Landlord shall have no further liability hereunder. Substantial damage shall be defined as damage that will cost over One Hundred Thousand Dollars ($100,000.00) to repair. If at any time during the last twelve (12) months of the Term of this Lease there is substantial damage to the Leased Premises such that Tenants use of the Leased Premises is materially impaired, in Tenants reasonable opinion, Tenant shall have the right to terminate this Lease as of the date of occurrence of such damage by giving written notice to Landlord within thirty (30) days after the date of occurrence of such damage, and Tenant shall have no further liability hereunder (except for those obligations and liabilities that expressly survive the termination of this Lease).
 ARTICLE 20

 20.2  Total Taking . If the Leased Premises are totally taken by condemnation, this Lease shall terminate on the date of taking.
 
 Partial Taking; Common Areas .
 
 (a) any portion of the Leased Premises is taken by condemnation, this Lease shall remain in effect, except that Tenant can elect to terminate this Lease if 33?% or more of the total number of square feet in the Leased Premises is taken.
 
 
 (b)  If any part of the Common Areas of the Complex is taken by condemnation, this Lease shall remain in full force and effect so long as there is no material interference with the access to the Leased Premises, except that if thirty percent (30%) or more of the Common Areas is taken by condemnation, Landlord or Tenant shall have the election to terminate this Lease pursuant to this Section.
 
 
 (c)  If fifty percent (50%) or more of the Building in which the Leased Premises are located is taken, Landlord shall have the election to terminate this Lease in the manner prescribed herein.
 
 
  20.4  Termination or Abatement .

The Terminating Party shall notify the Nonterminating Party of the date of termination, which date shall not be earlier than one hundred twenty (120) days after the Terminating Party has notified the Nonterminating Party of its election to terminate nor later than the date of taking. If Notice of Termination is not given within the Decision Period, this Lease shall continue in full force and effect except that Minimum Monthly Rent shall be reduced by subtracting therefrom an amount calculated by multiplying the Minimum Monthly Rent in effect prior to the taking by a fraction the numerator of which is the number of square feet taken from the Leased Premises and the denominator of which is the number of square feet in the Leased Premises prior to the taking.
 
 
 20.5  Restoration . If there is a partial taking of the Leased Premises and this Lease remains in full force and effect pursuant to this Article, Landlord, at its cost, shall accomplish all necessary restoration so that the Leased Premises is returned as near as possible to its condition immediately prior to the date of the taking, but in no event shall Landlord be obligated to expend more for such restoration than the extent of funds actually paid to Landlord by the condemnor. The foregoing limitation shall not apply ( i.e. , if such additional expenditure is necessary in order to render the Leased Premises tenantable, Landlord agrees to expend more for such restoration than the extent of funds actually paid to Landlord by condemnor) if Landlord determines, in its reasonable discretion and in good faith, that such expenditure is economically feasible.
 
 
 20.6  Award . Any award arising from the condemnation or the settlement thereof shall belong to and be paid to Landlord. However, Tenant may file a separate claim at Tenants sole cost and expense for Tenants trade fixtures, tangible personal property, goodwill, loss of business and relocation expenses. At all events, Landlord shall be solely entitled to all award in respect of the real property, including the bonus value of the leasehold.
 
 ARTICLE 21
 ASSIGNMENT AND SUBLETTING
 
 21.1 Lease is Personal . The purpose of this Lease is to transfer possession of the Leased Premises to Tenant for Tenants personal use in return for certain benefits, including rent, to be transferred to Landlord.

Except as permitted in Section 21.4(j) hereof, Tenant shall not suffer a Transfer of the Leased Premises or any interest therein, or any part thereof, or any right or privilege appurtenant thereto without the prior written consent of Landlord, and a consent to one Transfer of the Leased Premises shall not be deemed to be a consent to any subsequent Transfer of the Leased Premises. Any Transfer of the Leased Premises without such consent shall (i) be voidable, and (ii) terminate this Lease, in either case, at the option of Landlord. The consent by Landlord to any Transfer shall not automatically include the consent to the assignment or transferring of any lease renewal option rights or space option rights of the Leased Premises, special privileges or extra services granted to Tenant by this Lease, or addendum or amendment thereto or letter of agreement (and such options, rights, privileges or services shall terminate upon such assignment), unless Landlord specifically grants in writing such options, rights, privileges or services to such assignee or subtenant.
 
 
 21.4 When Consent Granted . The consent of Landlord to a Transfer shall not be unreasonably withheld, provided that it is agreed to be reasonable for Landlord to consider any of the following reasons, which list is not exclusive, in electing to deny consent:
 
 
 (a) The financial strength of the proposed transferee at the time of the proposed Transfer is not at least equal to that of Tenant at the time of execution of this Lease; provided, however, that the foregoing shall not apply to proposed subtenants of any portion of less than the entire Leased Premises;
 
 
 (b)  A proposed transferee whose impact or affect on the common facilities or the utility, efficiency or effectiveness of any utility or telecommunication system serving the Building or the Complex or the other occupants of the Complex would be adverse, disadvantageous or require unreasonable improvements or changes in any utility or telecommunication capacity currently serving the Building or the Complex;
 
 
 (c)  A proposed transferee whose occupancy will require a variation in the terms of this Lease (including, without limitation, a variation in the use clause) or which otherwise adversely affects any interest of Landlord, or whose occupancy or use may violate any restrictions set forth in this Lease, or any negative covenant as to use of the Leased Premises required by any other lease in the Building;
 
 
 (d)  The existence of any Default by Tenant under any provision of this Lease;
 
 
 (e)  A proposed transferee who is, or whose business is, subject to compliance with additional laws or other governmental requirements beyond those to which Tenant or Tenants business is subject;
 
 
 (f)  Either the proposed transferee, or any person or entity which directly or indirectly, controls, is controlled by, or is under common control with, the proposed transferee or an affiliate of the proposed transferee, is negotiating with Landlord to lease space in the Building or in the Complex at such time;
 
 
 (g)  The proposed Transferee is a governmental agency or unit, or a non-profit entity, or an existing tenant in the Complex;
 
 
 (h)  Landlord otherwise determines that the proposed Transfer would have the effect of unreasonably increasing the expenses associated with operating, maintaining and repairing the Building or the Complex;
 
 
 (i)  The proposed Transferee will use, store or handle Hazardous Materials (defined below) in or about the Leased Premises of a type, nature or quantity not then acceptable to Landlord; and
 
 
 (j) The proposed Transferee may be entitled, directly or indirectly, to diplomatic or sovereign immunity, regardless of whether the Transferee agrees to waive such diplomatic or sovereign immunity.
 
 
 (k)  Permitted Transfer. Notwithstanding anything to the contrary contained in this Article 21, (a) a transfer or subletting of all or a portion of the Leased Premises to an affiliate of Tenant (an entity which is controlled by, controls, or is under common control with, Tenant) (an  Affiliate ), (b) an assignment of the Leased Premises to an entity which acquires all or substantially all of the assets of Tenant, or (c) an assignment of the Leased Premises to an entity which is the resulting entity of a merger or consolidation of Tenant during the Term or any Renewal Term, shall not be deemed a Transfer or a Transfer of the Leased Premises under this Article 21 and shall not be subject to Landlords approval, and such Affiliate or other assignee (each a  Permitted Transferee ) shall not be deemed a transferee or sublessee under this Article 21, provided that Tenant notifies Landlord prior to any such assignment or sublease and promptly supplies Landlord with any documents or information reasonably requested by Landlord regarding such assignment or sublease or such Permitted Transferee, and further provided that such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease. If requested, Tenants successor shall sign a commercially reasonable form of assumption agreement.
 
 
 21.5 Procedure for Obtaining Consent . With respect to a Transfer requiring Landlords consent, Landlord need not commence its review of any proposed Transfer, or respond to any request by Tenant with respect to such, unless and until it has received from Tenant adequate descriptive information concerning the business to be conducted by the proposed transferee, the transferees financial capacity, and such other information as may reasonably be required in order to form a prudent judgment as to the acceptability of the proposed Transfer, including, without limitation, the following:

 (b)  Banking references of the proposed transferee;
 
 
 (c)  A resume of the business background and experience of the proposed transferee;
 
 
 ( d)  At least five (5) business and three (3) personal references for the proposed transferee; and

 Landlord shall consent or not consent to Tenants request for Landlords consent within fifteen (15) days following the date that Landlord has received all of the information described in this Section 21.5.
  
 21.6 Recapture . By written notice to Tenant (the  Termination Notice ) within fifteen (15) days following submission to Landlord by Tenant of the information specified in Section 21.5, Landlord may terminate this Lease with respect to (a) the entire Leased Premises in the event of an assignment of all of Tenants rights under this Lease, or (b) the portion of the Leased Premises that Tenant is proposing to sublet if such proposed subletting is for more than fifty percent (50%) of the Leased Premises and is for the remainder of the Term. If Landlord elects to terminate under the provisions hereof, and the area to be terminated is less than the entire Leased Premises, (i) an amendment to this Lease shall be executed in which Tenants obligations for Rent and other charges shall be reduced in proportion to the reduction in the size of the Leased Premises caused thereby by restating the description of the Leased Premises, and its monetary obligations hereunder shall be reduced by multiplying such obligations by a fraction, the numerator of which is the Rentable Area of the Leased Premises offered for sublease and the denominator of which is the Rentable Area of the Leased Premises immediately prior to such termination, as determined by Landlord in its sole and absolute discretion, and (ii) following the effective date of such recapture, Tenant shall have no further obligations with respect to such area (except for any obligations that either expressly survive the termination of this Lease or are related to events or omissions that arose prior to the effective date of such recapture).
  
 21.7 Reasonable Restriction . The restrictions on Transfer described in this Lease are acknowledged by Tenant to be reasonable for all purposes, including, without limitation, the provisions of California Civil Code (the  Code ) Section 1951.4(b)(2). Tenant expressly waives any rights which it might otherwise be deemed to possess pursuant to applicable law, including, without limitation, Section 1997.040 of the Code, to limit any remedy of Landlord pursuant to Section 1951.2 or 1951.4 of the Code by means of proof that enforcement of a restriction on use of the Leased Premises would be unreasonable.
 
 
 21.8  Effect of Transfer . If Landlord consents to a Transfer and does not elect to recapture as provided in Section 21.6, the following conditions shall apply:
 
 
 (a) Each and every covenant, condition or obligation imposed upon Tenant by this Lease and each and every right, remedy or benefit afforded Landlord by this Lease shall not be impaired or diminished as a result of such Transfer.
 
 (b) Except in the event of an assignment or sublease to a Permitted Transferee, Tenant shall pay to Landlord on a monthly basis, fifty percent (50%) of the excess of any sums of money, or other economic consideration received by Tenant from the Transferee in such month (whether or not for a period longer than one month), including higher rent, bonuses, key money, or the like, less reasonable and customary market-based leasing commissions, legal fees, advertising fees, the reasonable cost to Tenant of any Building-standard improvements paid for by Tenant in connection with such assignment or sublease, and any costs to separately demise the premises that is subject to the sublease from the remainder of the Leased Premises, including the installation of demising walls and the relocation of utilities, if necessary, over the aggregate of the total sums which Tenant pays Landlord under this Lease in such month, or the prorated portion thereof if the Leased Premises transferred is less than the entire Leased Premises. The amount so derived shall be paid with Tenants payment of Minimum Monthly Rent.
 
 
 (c)  No Transfer, whether or not consent of Landlord is required hereunder, shall relieve Tenant of its primary obligation to pay the rent and to perform all other obligations to be performed by Tenant hereunder except as otherwise expressly permitted by Landlord. The acceptance of rent by Landlord from any person shall not be deemed to be a waiver by Landlord of any provision of this Lease or to be a consent to any Transfer of the Leased Premises.
 
 
 (d)  If Landlord consents to a sublease, such sublease shall not extend beyond the expiration of the Term of this Lease.
 
 (e)  No Transfer shall be valid and no transferee shall take possession of the Leased Premises or any part thereof unless, Tenant shall deliver to Landlord, at least ten (10) days prior to the effective date of such Transfer, a duly executed duplicate original of the Transfer instrument in form satisfactory to Landlord which provides that (i) the transferee assumes Tenants obligations for the payment of rent and for the full and faithful observance and performance of the covenants, terms and conditions contained herein except to the limited extent provided in the instrument of transfer, (ii) such transferee will, at Landlords election, attorn directly to Landlord in the event Tenants Lease is terminated for any reason on the terms set forth in the instrument of transfer and (iii) such instrument of transfer contains such other assurances as Landlord reasonably deems necessary.
 
 21.9 Costs . Tenant shall reimburse Landlord as additional rent for Landlords reasonable costs and attorneys fees (not to exceed $2,000.00) incurred in conjunction with the processing and documentation of any proposed Transfer of the Leased Premises, whether or not consent is granted.
 
 
 21.10 Collection of Rent . If, without Landlords consent when required under this Article 21, this Lease is assigned, or any part of the Leased Premises is sublet or occupied by anyone other than Tenant or a Permitted Transferee or this Lease is encumbered (by operation of law or otherwise), Landlord may collect rent from the assignee, subtenant or occupant, and apply the net amount collected to the Rent herein reserved. No such collection shall be deemed a waiver of the provisions of this Article 21, an acceptance of the assignee, subtenant or occupant as tenant, or a release of Tenant from the performance of Tenants covenants hereunder, and in all cases Tenant shall remain fully liable for its obligations under this Lease unless otherwise expressly agreed by Landlord.
 
 ARTICLE 22
 ENTRY BY LANDLORD
 
 22.1  Rights of Landlord .

 (c)  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 rental loss that Tenant proves could be reasonably avoided; plus
 
 
 (d)  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 events would be likely to result therefrom; and
 
 
 (e)  At Landlords election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by the applicable law in the state in which the Leased Premises are located.
  
 The parties hereby agree and acknowledge that, in the event of Default by Tenant within the first three (3) years of the Initial Term for the Initial Premises, the amount of damages may include the amount of the brokerage commission paid to the Broker pursuant to Section 39.21 below; provided, however, that the total amount of the brokerage commission to be included in damages shall be automatically reduced by one-third for each year. By way of example, if Tenant Defaults in the second year of the Initial Term for the Initial Premises then sixty-six and six-tenths percent (66.6%) of the total brokerage commission paid by Landlord shall be included in the calculation of damages, and if Tenant Defaults in the third year of the Initial Term for the Initial Premises, then thirty-three and three-tenths percent (33.3%) of the total brokerage commission paid by Landlord shall be included in the calculation of damages.
 
 
 25.2  Definition . As used in Sections 25.1(a) and (b) above, the worth at the time of award is computed by allowing interest at the rate of ten percent (10%) per annum. As used in Section 25.1(c) above, the worth at the time of award is computed by discounting such amount at the discount rate of the Federal Reserve Bank for the region in which the Complex is located at the time of award plus one percent (1%).
 
 
 25.3  Personal Property . In the event of any default by Tenant, Landlord shall also have the right and option, with or without terminating this Lease, to do any one or combination of the following:
 
 
 (a)  to reenter the Leased Premises and remove all persons and property from the Leased Premises;
 
 
 (b)  to require Tenant to forthwith remove such property.
 
 
 Landlord shall have the sole right to take exclusive possession of such property and to use it or rent, until all defaults are cured. If Landlord shall remove property from the Leased Premises, Landlord may, in its sole and absolute discretion, store such property in the Complex, in a public warehouse or elsewhere. All costs incurred by Landlord under this Section, including, without limitation, those for removal and storage (including, without limitation, reasonable charges imposed by Landlord for storage within the Complex), shall be at the sole cost of and for the account of Tenant. The rights stated herein are in addition to Landlords rights described in Article 17.
 
 
 25.4  Recovery of Rent; Reletting .
 
 
 (a) In the event of the abandonment of the Leased Premises by Tenant or in the event that Landlord shall elect to reenter as provided in Section 25.3 above, shall take possession of the Leased Premises pursuant to legal proceeding or pursuant to any notice provided by law, then if Landlord does not elect to terminate this Lease as provided in Section 25.1 above, this Lease shall continue in effect for so long as Landlord does not terminate Tenants right to possession, and Landlord may enforce all its rights and remedies under this Lease, including, without limitation, Landlords right from time to time, without terminating this Lease, to either recover all rental as it becomes due or relet the Leased Premises or any part thereof for such term or terms and at such rental or rentals and upon such other terms and conditions as Landlord, in its sole discretion, may deem advisable with the right to make alterations and repairs to the Leased Premises. Acts of maintenance or preservation or efforts to relet the Leased Premises or the appointment of a receiver upon initiation of Landlord or other legal proceeding granting Landlord or its agent possession to protect Landlords interest under this Lease shall not constitute a termination of Tenants right to possession.
 
 
 (b)  In the event that Landlord shall elect to so relet, then rentals received by Landlord from such reletting shall be applied: first, to the payment of any indebtedness other than rent due hereunder from Tenant to Landlord; second, to the payment of any cost of such reletting; third, to the payment of the cost of any alterations and repairs to the Leased Premises, as Landlord shall consider advisable for the purpose of reletting the Leased Premises or portion thereof; fourth, to the payment of rent due and unpaid hereunder; and the residue, if any, shall be held by Landlord and applied in payment of future rent as the same may become due and payable hereunder. Should that portion of such rentals received from such reletting during any month, which is applied by the payment of rent hereunder, be less than the rent payable during that month by Tenant hereunder, then Tenant shall pay such deficiency to Landlord immediately upon demand therefor by Landlord. Such deficiency shall be calculated and paid monthly. Tenant shall also pay to Landlord, as soon as ascertained, any costs and expenses incurred by Landlord in such reletting or in making such alterations and repairs not covered by the rentals received from such reletting.
 
 
 (c)  No reentry or taking possession of the Leased Premises or any other action under this Section shall be construed as an election to terminate this Lease unless a written notice of such intention be given to Tenant or unless the termination thereof be decreed by a court of competent jurisdiction. Notwithstanding any reletting without termination by Landlord because of any Default by Tenant, Landlord may at any time after such reletting elect to terminate this Lease for any such Default.
 
 
 (d)  Landlord has the remedy described in California Civil Code Section 1951.4 (Landlord may continue Lease in effect after Tenants breach and abandonment and recover rent as it becomes due, if Tenant has right to sublet or assign, subject only to reasonable limitations).
 
 
 (e)  Tenants Subleases. Whether or not Landlord elects to terminate this Lease on account of any Default by Tenant, Landlord may:
 
 
 (1)  Terminate any sublease, license, concession, or other consensual arrangement for possession entered into by Tenant and affecting the Leased Premises or any portion thereof; or
 
 
 (2)  Choose to succeed to Tenants interest in such an arrangement. If Landlord elects to succeed to Tenants interest in such an arrangement, Tenant shall, as of the date of notice by Landlord of that election, have no further right to, or interest in, the Rent or other consideration receivable under that arrangement.
 
 25.5 No Waiver . Efforts by Landlord to mitigate the damages caused by Tenants Default in this Lease shall not constitute a waiver of Landlords right to recover damages hereunder.
 
 
 25.6  Curing Defaults . If Tenant defaults in the performance of its obligations under this Lease after the expiration of any applicable cure periods, Landlord, without waiving such default, may perform such obligation at Tenants expense: (a) immediately, and without notice, in the case of emergency or if the default (i) materially interferes with the use by any other tenant of the Building, (ii) materially interferes with the efficient operation of the Building, (iii) results in a violation of any federal, state or local law, rule, ordinance or regulation, or (iv) results or will result in a cancellation of any insurance policy maintained by Landlord, and (b) in any other case if such default continues after twenty (20) days from the date Landlord gives notice of Landlords intention to perform the defaulted obligation (or, if such default cannot be cured within such twenty (20) day period, if Tenant fails to diligently commence such cure within such twenty (20) day period). All costs and expenses incurred by Landlord in connection with any such performance by it and all costs and expenses, including reasonable counsel fees and disbursements, incurred by Landlord in any action or proceeding (including any unlawful detainer proceeding) brought by Landlord to enforce any obligation of Tenant under this lease and/or right of Landlord in or to the Leased Premises, shall be paid by Tenant to Landlord on demand, with interest thereon at the rate provided in this Lease for past due sums from the date incurred by Landlord. Except as expressly provided to the contrary in this Lease, all costs and expenses which, pursuant to this Lease are incurred by Landlord and payable to Landlord by Tenant, and all charges, amounts and sums payable to Landlord by Tenant for any property, material, labor, utility or other services which, pursuant to this Lease or at the request and for the account of Tenant, are provided, furnished or rendered by Landlord, shall become due and payable by Tenant to Landlord in accordance with the terms of the bills rendered by Landlord to Tenant.
 
 
 25.7  Cumulative Remedies . The various rights, options, election powers, and remedies of Landlord contained in this Article and elsewhere in this Lease shall be construed as cumulative and no one of them exclusive of any others or of any legal or equitable remedy which Landlord might otherwise have in the event of breach or default, and the exercise of one right or remedy by Landlord shall not in any way impair its right to any other right or remedy.
 
 ARTICLE 26
 BANKRUPTCY
 
 26.1  Bankruptcy Events . If at any time during the Term of this Lease there shall be filed by or against Tenant in any court pursuant to any statute either of the United States or of any state a petition in bankruptcy or insolvency or for reorganization or for the appointment of a receiver or trustee of all or a portion of Tenants property, or if a receiver or trustee takes possession of any of the assets of Tenant, or if the leasehold interest herein passes to a receiver, or if Tenant makes an assignment for the benefit of creditors or petitions for or enters into an arrangement (any of which are referred to herein as a  bankruptcy event ), then the following provisions shall apply:
 
 
 (a) Assume or Reject. At all events any receiver or trustee in bankruptcy or Tenant as debtor in possession ( debtor ) shall either expressly assume or reject this Lease within the earlier of sixty (60) days following the entry of an Order for Relief or such earlier period of time provided by law.
 
 (b)  Cure. In the event of an assumption of this Lease by a debtor, receiver or trustee, such debtor, receiver or trustee shall immediately after such assumption (1) cure any default or provide adequate assurances that defaults will be promptly cured; and (2) compensate Landlord for actual pecuniary loss or provide adequate assurances that compensation will be made for actual pecuniary loss; and (3) provide adequate assurance of future performance.
  
 (c)  Adequate Assurance. For the purposes of Section 26.1(b), adequate assurance of future performance of all obligations under this Lease shall include, but is not limited to:
 
 
 (1) written assurance that rent and any other consideration due under this Lease shall first be paid before any other of Tenants costs of operation of its business in the Leased Premises is paid;
  
 (2)  written agreement that assumption of this Lease will not cause a breach of any provision hereof including, but not limited to, any provision relating to use or exclusivity in this or any other Lease, or agreement relating to the Leased Premises, or if such a breach is caused, the debtor, receiver or trustee will indemnify Landlord against such loss (including costs of suit and attorneys fees), occasioned by such breach;
 
 
 (d)  Landlords Obligation. Where a Default exists under this Lease, the party assuming this Lease may not require Landlord to provide services or supplies incidental to this Lease before its assumption by such trustee or debtor, unless Landlord is compensated under the terms of this Lease for such services and supplies provided before the assumption of such Lease.
 
 
 (e)  Assignment. The debtor, receiver, or trustee may assign this Lease only if adequate assurance of future performance by the assignee is provided, whether or not there has been a Default under this Lease. Any consideration paid by any assignee in excess of the rental reserved in this Lease shall be the sole property of, and paid to, Landlord. Upon assignment by the debtor or trustee, the obligations of this Lease shall be deemed to have been assumed, and the assignee shall execute an assignment agreement on request of Landlord.
 
 
 (f) Fair Value. Landlord shall be entitled to the fair market value for the Leased Premises and the services provided by Landlord (but in no event less than the rental reserved in this Lease) subsequent to the commencement of a bankruptcy event.
 
 
 (g)  Reservation of Rights. Landlord specifically reserves any and all remedies available to Landlord in Article 25 hereof or at law or in equity in respect of a bankruptcy event by Tenant to the extent such remedies are permitted by law.
 
 ARTICLE 27
 SURRENDER OF LEASE
 
 27.1 No Merger . The voluntary or other surrender of this Lease by Tenant, or a mutual cancellation thereof, shall not work as a merger, and shall, at the option of Landlord, terminate all or any existing subleases or subtenancies, or may, at the option of Landlord, operate as an assignment to it of any or all such subleases or subtenancies.
 
 Restoration . Tenant shall return the Leased Premises to Landlord at the expiration or earlier termination of this Lease in good and sanitary order, condition and repair; free of rubble and debris; broom clean; reasonable wear and tear, damage by casualty or condemnation, and repairs and maintenance obligations of Landlord excepted. All damage to the Leased Premises caused by the removal of any trade fixtures and other personal property that Tenant is permitted to remove under the terms of this Lease and/or such restoration shall be repaired by Tenant at its sole cost and expense prior to termination. Landlord hereby agrees that Tenant shall not be required to remove the initial Tenant Improvements at the expiration or termination of the Term.
 
 ARTICLE 28
 LANDLORDS DEFAULT AND EXCULPATION
 
 Limited Liability . In the event of default, breach, or violation by Landlord (which term includes Landlords partners, members, managers, co-venturers, co-tenants, officers, directors, employees, agents, or representatives) of any Landlords obligations under this Lease, Landlords liability to Tenant shall be limited to its ownership interest in the Building or the proceeds of a public sale of such interest pursuant to foreclosure of a judgment against Landlord. Landlord (as defined in Section 28.1) shall not be personally liable for any deficiency beyond its interest in the Building.
 
 28.2  Landlords Liability . Any Building employee to whom any property shall be entrusted by or on behalf of Tenant shall be deemed to be acting as Tenants agent with respect to such property and neither Landlord nor its agents shall be liable for any damage to such property, or for the loss of or damage to any property of Tenant by theft or otherwise. Landlord, its property manager and Landlords lender shall not be liable for any injury or damage to persons or property or interruption of Tenants business resulting from fire or other casualty, any damage caused by other tenants or persons in the Building, the Parking Garage, the Common Area or the Complex, or by construction of any private, public or quasi-public work.
 
 ARTICLE 29
 ATTORNEYS FEES
 
 29.1 Attorneys Fees . In the event of any litigation or arbitration (if each party in its sole and absolute discretion elects to use arbitration) proceeding between the parties with respect to this Lease, then all reasonable costs and expenses, including, without limitation, all reasonable professional fees such as appraisers, accountants and attorneys fees, incurred by the prevailing party therein shall be paid or reimbursed by the other party. The  prevailing party  means the party determined by the court or arbitrator (if the parties elected to use arbitration) to be the one in whose favor a judgment is rendered. Further, in the event of any default by a party under this Agreement after notice and the expiration of the applicable cure period, such defaulting party shall pay expenses and attorneys fees incurred by the other party in connection with such default, whether or not any litigation is commenced. The provisions of this Section shall survive the expiration or termination of this Lease.
 
 ARTICLE 30
 NOTICES
 
 30.1  Writing . All notices, demands and requests required or permitted to be given or made under any provision of this Lease shall be in writing and shall be given or made by personal service or by mailing same by registered or certified mail, return receipt requested, postage prepaid, or overnight by Fed Ex or reputable courier which provides written evidence of delivery or other means of confirmation of delivery (such as computer confirmation by Fed Ex), or by facsimile with facsimile confirmation that the notice was sent, addressed to the respective party at the address set forth in Section 1.2 of this Lease or at such other address as the party may from time to time designate, by a written notice sent to the other in the manner aforesaid.
 
 
 30.2  Effective Date . Any such notice, demand or request ( notice ) given by overnight courier or personal service shall be deemed given on the earlier of the date of actual receipt or the date on which delivery is refused. Notice given by facsimile shall be deemed given on the day on which the facsimile is sent; and notice given by registered or certified mail shall be deemed delivered on the third (3rd) day after the date so mailed.
 
 
 30.3  Authorization to Receive . Each person and/or entity whose signature is affixed to this Lease as Tenant or as guarantor of Tenants obligations ( obligor ) designates such other obligor its agent for the purpose of receiving any notice pertaining to this Lease or service of process in the event of any litigation or dispute arising from any obligation imposed by this Lease.
 ARTICLE 31
 SUBORDINATION AND FINANCING PROVISIONS
 
 Priority of Encumbrances . This Lease is subordinate to any ground lease, mortgage, deed of trust or any other hypothecation for security now or hereafter placed upon the real property of which the Leased Premises are a part and to any and all advances made on the security thereof and to all renewals, modifications, consolidations, replacements and extensions thereof. Notwithstanding such subordination, Tenants right to quiet possession of the Leased Premises shall not be disturbed if Tenant is not in Default and so long as Tenant shall pay the rent and observe and perform all the provisions of this Lease, unless this Lease is otherwise terminated pursuant to its terms. If any mortgagee, trustee or ground lessor shall elect to have this Lease prior to the lien of its mortgage, deed of trust or ground lease, and shall give written notice thereof to Tenant, this Lease shall be deemed prior to such mortgage, deed of trust or ground lease, whether this Lease is dated prior or subsequent to the date of said mortgage, deed of trust or ground lease or the date of recording thereof. Notwithstanding the terms of this Section 31.1, Landlord shall use commercially reasonable efforts to obtain from its current mortgagee a subordination, non-disturbance and attornment agreement (an  SNDA ) in substantially the form attached hereto as Exhibit J or such other form as reasonably acceptable to Tenant. If for any reason Landlord fails to so deliver to Tenant the SNDA within thirty (30) days after the date of mutual execution and delivery of this Lease, Tenant, as its sole remedy for such failure, may terminate this Lease by providing written notice to Landlord, which notice shall be given, if at all, not later than forty-five (45) days after the date of mutual execution and delivery of this Lease. In the event that this Lease is terminated in connection with the foregoing, Landlord shall immediately return to Tenant any prepaid Rent, Letter of Credit or other amounts delivered by Tenant, and the parties shall hereafter have no further obligations to one another. With respect to any future mortgage, Landlord shall use commercially reasonable efforts to provide Tenant with an SNDA in favor of Tenant from such mortgagee; provided, however, that as a condition to the subordination of this Lease to a future mortgage or deed of trust, Tenant shall receive from the applicable mortgagee a written non-disturbance agreement in a form reasonably acceptable to Tenant providing for the recognition of Tenants interests under this Lease in the event of a foreclosure of such mortgagees security interest.
 
 
 31.2  Execution of Documents . Tenant agrees to execute any documents required to further effectuate such subordination or to make this Lease prior to the lien of any mortgage, deed of trust or ground lease, as the case may be, if requested by Landlord or any lender, provided that Tenants rights hereunder are not materially adversely impacted. It is understood by all parties that Tenants failure to execute the subordination documents referred to above may cause Landlord serious financial damage by causing the failure of a financing or sale transaction.
 
 
 31.3  Attornment . If the holder of any ground lease, mortgage, deed of trust or security described above (or its successor-in-interest), enforces its remedies provided by law or under the pertinent mortgage, deed of trust or security instrument and succeeds to Landlords interest in the Leased Premises, Tenant shall, upon request of any person succeeding to the interest of such lender as result of such enforcement, automatically become the tenant of said successor-in-interest without change in the terms or other provisions of this Lease; provided, however, that said successor-in-interest shall not be (i) bound by any payment of rent for more than thirty (30) days in advance, except prepayment in the nature of security for the performance by Tenant of its obligations under this Lease or except to the extent such prepayment is required by the terms of the Lease, (ii) liable for any act or omission of any previous landlord (including Landlord) except that any successor landlord shall be liable for the cure of any continuing Landlord default that relates to the physical condition of the Leased Premises or the Building, (iii) subject to any offset, defense, recoupment or counterclaim that Tenant may have given to any previous landlord (including Landlord), other than rental abatement for loss or condemnation expressly provided for herein, or (iv) liable for any deposit that Tenant may have given to any previous landlord (including Landlord) that has not, as such, been transferred to said successor-in-interest. Within ten (10) Business Days after receipt of request by said successor-in-interest, Tenant shall execute and deliver an instrument or instruments confirming such attornment, including a non-disturbance, attornment and subordination agreement in a form required by any such successor-in-interest.
 
 31.4  Notice and Right to Cure Default . Tenant agrees to give any mortgagee(s) and/or trust deed holders, by registered mail, a copy of any notice of default served upon Landlord, provided that prior to such notice Tenant has been notified, in writing (by way of Notice of Assignment of Rents and Leases, or otherwise), of the address of such mortgagees and/or trust deed holders. Tenant further agrees that if Landlord shall have failed to cure such default within the time provided for in this Lease, then the mortgagees and/or trust deed holders shall have an additional fifteen (15) Business Days within which to cure such default or, if such default cannot be cured within that time, then such additional time as may be necessary if, within such fifteen (15) Business Days, any mortgagee and/or trust deed holder has commenced and is diligently pursuing the remedies necessary to cure such default (including, but not limited to, commencement of foreclosure proceedings, if necessary to effect such cure), in which event this Lease shall not be terminated while such remedies are being so diligently pursued.
 
 
 31.5  Reasonable Accommodations . In connection with any financing of the Building, Tenant shall consent to any reasonable modifications of this Lease requested by any lending institution, provided that such modifications do not increase the Rent, unreasonably increase the obligations, or unreasonably and adversely affect the rights, of Tenant under this Lease.
  ARTICLE 32
 ESTOPPEL CERTIFICATES
 
 32.1 Execution by Tenant and Landlord . Within ten (10) Business Days after receipt of written request by the other party, Landlord or Tenant shall execute and deliver to the other party an estoppel certificate acknowledging such facts regarding this Lease as such party may reasonably require, including, without limitation, that to the extent of such partys knowledge (i) this Lease is in full force and effect, binding and enforceable in accordance with its terms and unmodified (or if modified, specifying the written modification documents); (ii) no default exists on the part of Landlord or Tenant under this Lease (or if so, specify); (iii) there are no events which with the passage of time, or the giving of notice, or both, would create a default under this Lease (or if so, specify); (iv) no rent in excess of one months rent has been paid in advance (or if so, specify); (v) such party has not received any written notice of any other sale, assignment, transfer, mortgage or pledge of this Lease or the rent due hereunder (or if so, specify); and (vi) such party has no defense, setoff, recoupment or counterclaim against the other party (or if so, specify). Any such estoppel certificate may be relied upon by such parties as are reasonably requested by the other, including any lender and any prospective purchaser of the Building or the Complex or any interest therein. Failure to comply with this Article shall be a material breach of this Lease by such party.
 
 
 32.2  Financing . If Landlord desires to finance or refinance the Leased Premises, or any part thereof, or the Building, Tenant hereby agrees to deliver to any lender designated by Landlord such financial statements of Tenant as may be reasonably required by such lender. Such statements shall include the past three (3) years financial statements of Tenant. All such financial statements shall be received by Landlord and such lender in confidence and shall be used only for the purposes herein set forth. Notwithstanding the foregoing, Landlord shall not request financial statements more than once in each consecutive two (2) year period during the Term unless Tenant is in default or Landlord reasonably believes that there has been an adverse change in Tenants financial position since the last financial statement provided to Landlord.
  ARTICLE 33
 RENEWAL OPTIONS
 
 33.1  Grant of Option; Conditions . Tenant shall have the right to extend the Term (the  Renewal Option ), for two (2) additional periods of five (5) years each (each, a  Renewal Term ), commencing on the day following the Termination Date of the Initial Term, or on the day following the last day of the prior Renewal Term, as applicable (the  Applicable Expiration Date ), and ending on the fifth (5th) anniversary of the Termination Date or on the last day of the prior Renewal Term, as applicable. Such Renewal Options shall be personal to Tenant and to any Permitted Transferee and shall be exercisable if:
  
  
 (a)  Landlord receives notice of exercise ( Initial Renewal Notice ) not less than twelve (12) full calendar months prior to the Applicable Expiration Date and not more than fifteen (15) full calendar months prior to the Applicable Expiration Date; and
 
 
 (b)  Tenant is not in Default under this Lease at the time that Tenant delivers its Initial Renewal Notice or at the time Tenant delivers its Binding Notice (as defined below); and
 
 
 (c)  The original Tenant named under this Lease or any Permitted Transferee ( Original Tenant ) is occupying at least 100,000 rentable square feet of the Leased Premises at the time that Tenant delivers its Initial Renewal Notice and at the time Tenant delivers its Binding Notice.
 
 33.2  Terms Applicable to Leased Premises During Renewal Term .
 
 (a)  The initial Minimum Monthly Rent rate per rentable square foot for the Leased Premises during the Renewal Term shall be equal to ninety-five percent (95%) of the Prevailing Market (hereinafter defined) rate per rentable square foot for the Leased Premises, with the Prevailing Market rate being subject to adjustment during the Renewal Term, in accordance with the determination of the Prevailing Market rate described in Section 33.3 below. Minimum Monthly Rent during the Renewal Term shall increase, if at all, in accordance with the increases assumed in the determination of the Prevailing Market rate. Minimum Monthly Rent attributable to the Leased Premises shall be payable in monthly installments in accordance with the terms and conditions of Article 5 of this Lease.
  
 (b)  Tenant shall pay Additional Rent for the Leased Premises during the Renewal Term in accordance with Article 6 of this Lease, and the manner and method in which Tenant reimburses Landlord for Tenants share of Operating Costs, Taxes and Insurance, shall be some of the factors considered in determining the Prevailing Market rate for the Renewal Term.
 
 
 33.3 Procedure for Determining Prevailing Market . Within thirty (30) days after receipt of Tenants Initial Renewal Notice, Landlord shall advise Tenant of the applicable Minimum Monthly Rent rate for the Leased Premises for the Renewal Term. Tenant, within thirty (30) days after the date on which Landlord advises Tenant of the applicable Minimum Monthly Rent rate for the Renewal Term, shall either (i) give Landlord final binding written notice ( Binding Notice ) of Tenants exercise of its Renewal Option, or (ii) if Tenant disagrees with Landlords determination, provide Landlord with written notice of rejection (the  Rejection Notice ). If Tenant fails to provide Landlord with either a Binding Notice or Rejection Notice within such thirty (30) day period, Tenants Renewal Option shall be null and void and of no further force and effect. If Tenant provides Landlord with a Binding Notice, Landlord and Tenant shall enter into the Renewal Amendment (as defined below) upon the terms and conditions set forth herein. If Tenant provides Landlord with a Rejection Notice, Landlord and Tenant shall work together in good faith to agree upon the Prevailing Market rate for the Leased Premises during the Renewal Term. When Landlord and Tenant have agreed upon the Prevailing Market rate for the Leased Premises, such agreement shall be reflected in a written agreement between Landlord and Tenant, whether in a letter or otherwise, and Landlord and Tenant shall enter into the Renewal Amendment in accordance with the terms and conditions hereof. If the parties have not reached agreement on the Prevailing Market rate by the date that is sixty (60) days after Tenants delivery of the Rejection Notice (the  Initial Rent Determination Period ) to Landlord, then within ten (10) days following the expiration of the Initial Rent Determination Period, Tenant may elect, by giving written notice to Landlord, to either (i) submit to binding arbitration for a determination of the Prevailing Market rate as set forth herein, or (ii) extend the Term of this Lease for a period of six (6) to twelve (12) months, as specified by Tenant in its written notice of election (which notice and election shall be irrevocable), at a Minimum Monthly Rent equal to one hundred ten percent (110%) of the then-current Minimum Monthly Rent plus payment of all additional rent. If Tenant elects alternative (ii) and extends the Term of this Lease for a period of six (6) to twelve (12) months, such extension shall be upon and subject to all of the terms and provisions of this Lease, and this Lease shall automatically terminate at the end of the applicable period so specified by Tenant; provided that Tenant shall have no further option to extend or renew this Lease. The failure of Tenant to make an election of either alternative (i) or (ii) above within the aforesaid ten (10) day period shall be conclusively and irrevocably deemed to be an election by Tenant to elect alternative (i). If Tenant elects, or is deemed to have elected, to submit to binding arbitration, then each party shall appoint an appraiser and shall give to the other party the identity of the appraiser no later than the date that is twenty (20) days after the expiration of the Initial Rent Determination Period. If either party fails to appoint an appraiser by such date, the sole appraiser appointed, if any, shall determine the Prevailing Market rate. If either party fails to appoint an appraiser as set forth herein, then Landlords determination of the Prevailing Market rate shall be final and binding upon the parties. If two appraisers are appointed, they shall immediately meet and attempt to agree upon such Prevailing Market rate. If the appraisers cannot reach agreement on the Prevailing Market rate by the date that is fifteen (15) days after appointment of the appraisers by the parties hereto, each appraiser shall submit a determination of the Prevailing Market rate to Landlord and Tenant not later than twenty (20) days after such appointment. If only one (1) appraiser submits its determination of the Prevailing Market rate within such twenty (20) day period, then the Prevailing Market rate shall be deemed to equal such appraisers determination. If neither appraiser timely submits its determination of the Prevailing Market rate, then Landlords determination of the Prevailing Market rate shall be final and binding upon the parties. If the determinations of the Prevailing Market rate made by these two appraisers differ by five percent (5%) or less of the higher of the two determinations, the Prevailing Market rate shall be the average of the two determinations. If the determinations vary by more than five percent (5%) of the higher of the two determinations, the two appraisers shall within ten (10) days after submission of their determinations, appoint a third appraiser. If the two appraisers shall be unable to agree on the selection of a third appraiser within the ten (10) day period, then either Tenant or Landlord may request such appointment by petitioning the presiding judge of the Superior Court in and for the County of Santa Clara. Such third appraiser shall, within thirty (30) days after appointment, make a determination of the Prevailing Market rate and submit such determination to Landlord and Tenant. The Prevailing Market rate shall be the determination of the Prevailing Market rate submitted by the original two appraisers that is closer to the Prevailing Market rate determination of the third appraiser. If the third appraisers determination is exactly equal to the arithmetic mean of the Prevailing Market rate determinations of the original two appraisers, then the Prevailing Market rate shall be the average of the original two determinations. For purposes of this Section, appraiser shall mean an MAI designated appraiser with not less than five (5) years of full-time commercial appraisal experience in the County of Santa Clara. Each party shall bear the fees and costs incurred by each partys appraiser in connection with the determination of the Prevailing Market rate and all fees and costs incurred by the third appraiser, if any, in connection with the determination of the Prevailing Market rate shall be shared equally by Landlord and Tenant. If the determination of the Prevailing Market rate has not been made by the Applicable Expiration Date, then Tenant shall (i) continue to pay monthly Minimum Monthly Rent at the rate of one hundred ten percent (110%) of the monthly Minimum Monthly Rent for the last month of the Term (the  Arbitration Period Minimum Monthly Rent ), as well as any Additional Rent due under this Lease and (ii) pay to Landlord, or receive as a refund from Landlord, as applicable, on the first day of the month after the determination of the Prevailing Market rate is made, an amount, if any, equal to the difference between the Arbitration Period Minimum Monthly Rent that was paid to Landlord and the Minimum Monthly Rent for the Renewal Term that should have been paid to Landlord as the monthly Minimum Monthly Rent for the Renewal Term as determined hereunder.

During the Term (including any Renewal Term), Tenant shall have a continuing right of first offer (the  First Offer Right ) with respect to space located in the Building (each, an  Offer Space ) for a term commencing after the expiration or termination of the first lease Landlord enters into after the date of this Lease and subject to any extension, expansion or other rights granted under such lease, with respect to such space. Such First Offer Right shall be personal to Tenant and to any Permitted Transferee and shall be exercisable if:
 
 
 (a) Landlord receives an Initial Offer Notice (as defined below); and
 
 
 (b)  Tenant is not in default under this Lease beyond any applicable cure periods at the time that Tenant delivers its Initial Offer Notice or at the time Tenant delivers its Acceptance Notice (as defined below); and
 
 
 (c)  Original Tenant (including any Permitted Transferee) is occupying at least 100,000 rentable square feet of the Leased Premises at the time that Tenant delivers its Initial Offer Notice and at the time Tenant delivers its Acceptance Notice; and

 35.2 Procedure for Exercise of First Offer Right .
 
 
 (a) If, at any time during the Term, Tenant desires to exercise its First Offer Right, Tenant shall deliver a written notice to Landlord requesting that Landlord notify Tenant of the availability of space in the Building ( Initial Offer Notice ). The Initial Offer Notice shall specify the approximate amount of additional space that Tenant desires to lease in the Building.
 
 
 (b)  Within fifteen (15) Business Days following Landlords receipt of the Initial Offer Notice, Landlord shall inform Tenant in writing of Offer Space, if any, that is then available for lease in the Building and the terms upon which Landlord would be willing to lease such Offer Space to Tenant (the  Landlord Notice ); provided, however, that the parties agree that the Minimum Monthly Rent amount shall not exceed the then existing Prevailing Market rate (as defined in Section 33.5 above). The Landlord Notice shall, with respect to any Offer Space, (1) state Landlords willingness to lease the Offer Space, (2) identify a proposed commencement date, (3) state all of the material monetary terms (including, without limitation, the Minimum Monthly Rent) proposed by Landlord for the Offer Space, and (4) expressly identify itself as a Landlord Notice.
 
 
  (c)  Tenant shall, within ten (10) days following receipt of such Landlord Notice, deliver to Landlord written notice of its election to accept or reject Landlords offer to lease such Offer Space on the terms set forth in the Landlord Notice (the  Acceptance Notice ). If (i) Tenant rejects Landlords offer to lease the Offer Space in the Building, or (ii) if Tenant fails to respond to Landlords notice within such ten (10) day period, or (iii) if Tenant fails to accept such offer on the express terms set forth in the Landlord Notice, Landlord shall have no further obligation to Tenant with respect to such Offer Space or to provide a Landlord Notice to Tenant with respect to any other Offer Space until such time that Tenant delivers to Landlord another Initial Offer Notice. In no event may Tenant submit more than one Initial Offer Notice to Landlord more than once in any six (6) month period during the Term. If Tenant accepts Landlords offer to lease Offer Space in the Building on the terms set forth in the Landlord Notice, the parties will enter into a lease amendment to reflect the commencement date of the term for the applicable Offer Space (the  Offer Commencement Date ) and the changes in Minimum Monthly Rent, rentable square footage of the Leased Premises, Tenants Proportionate Share and other appropriate terms (an  Offer Amendment ). A copy of the Offer Amendment shall be sent to Tenant within a reasonable time after Landlords receipt of the applicable Acceptance Notice, and Tenant shall execute and return the Offer Amendment to Landlord within five (5) days thereafter. If Tenant fails to deliver such Offer Amendment within such five (5) day period, Landlord may, in it sole discretion, terminate Tenants rights to such Offer Space or deem such failure to be a valid exercise of such First Offer Right, in which case such First Offer Right shall be fully effective whether or not an Offer Amendment is executed.
 
 
 35.3 Terms .
 
 
 (a) Each Offer Space (including improvements and personalty, if any) shall be accepted by Tenant in its as-built condition and configuration existing on the earlier of the date Tenant takes possession of such Offer Space or as of the Offer Commencement Date.
 
 
 (b) The term for each Offer Space shall commence on the Offer Commencement Date for such Offer Space, and shall end, unless sooner terminated pursuant to the terms of this Lease, on the date specified in Landlords Notice. If Landlord is delayed delivering possession of any Offer Space for any reason whatsoever, Landlord shall not be liable to Tenant for any loss or damage resulting therefrom.
 
 
 (c)  Each Offer Space shall be considered a part of the Leased Premises, subject to all the terms and conditions of this Lease (except to the extent otherwise specified in Landlords Notice with respect to such Offer Space), except that no allowances or credits provided to Tenant with respect to the Initial Premises shall apply to any Offer Space, except as may be specifically provided otherwise in this Article.
 
 ARTICLE 36
 LIMITED RIGHT OF FIRST REFUSAL
 
 36.1  Subject to the terms of this Article 36, Tenant shall have a limited right of first refusal (the  Right of First Refusal ) during the Term and any Renewal Term to lease space in the Building. The Right of First Refusal is personal to WebEx Communications, Inc. and may not be exercised by any sublessee or assignee, or by any other successor or assign, of WebEx Communications, Inc. The Right of First Refusal shall be effective only if Tenant is not in Default under this Lease, nor has any event occurred which with the giving of notice or the passage of time, or both, would constitute a Default hereunder, either at the time of the applicable exercise of the Right of First Refusal or on the applicable First Refusal Commencement Date (as hereinafter defined).
 
 
 36.2 In the event that Landlord receives a bona fide offer (an  Offer ), that Landlord is willing to accept, to lease a portion of the Building to any department or division of Centra Software, Genesys Conferencing, Raindance Communications, IBM, Oracle, Macromedia, Microsoft or Cisco Systems whose primary activity in the Building is the development or sale of web conferencing equipment or software (each, a  Direct Competitor ) (the space that is the subject of such Offer being herein referred to as the  First Refusal Space ), then provided such Offer was signed by an authorized representative of such Direct Competitor or its parent company, Landlord shall notify Tenant in writing of the terms and conditions of such Offer along with written certification by Landlord that Landlord is willing to enter into a lease with such Direct Competitor on the terms contained in such Offer (each such written notice and certification being herein referred to as a  First Refusal Space Availability Notice ). If the First Refusal Availability Notice is delivered by Landlord prior to the third anniversary of the date of this Lease, then Tenant shall thereafter have the right to lease such First Refusal Space on the same terms and conditions as set forth herein. If the First Refusal Availability Notice is delivered by Landlord following the third anniversary of the date of this Lease, then Tenant shall thereafter have the right to lease such First Refusal Space on the same terms and conditions specified in the First Refusal Space Availability Notice. In order to exercise any such right, Tenant must deliver a written notice (a  First Refusal Acceptance Notice ) to Landlord not later than ten (10) days after Tenants receipt of the First Refusal Space Availability Notice. If Tenant fails to deliver a First Refusal Acceptance Notice to Landlord on a timely basis as provided in the preceding sentence (time being of the essence), then Tenant shall be deemed to have elected not to exercise the Right of First Refusal as to such First Refusal Space. Notwithstanding anything herein to the contrary, Landlord will obtain an Offer and otherwise comply with the terms of this Article 36 prior to entering into any lease with a Direct Competitor.
 
 
 36.3 In the event Tenant fails to exercise its Right of First Refusal with respect to any First Refusal Space in a timely manner as provided herein, Landlord shall thereafter have the right to lease such First Refusal Space to such Direct Competitor on materially the same terms and conditions as set forth in the Offer. If Tenant validly exercises such Right of First Refusal, then (i) Tenants lease of the applicable First Refusal Space shall commence on a date (a  First Refusal Commencement Date ) specified in the First Refusal Space Availability Notice (and as contained in the Offer), (ii) the First Refusal Space shall be leased to Tenant upon the terms and conditions determined pursuant to 36.2 above, (iii) Tenants Proportionate Share of the Building shall be increased to reflect the applicable First Refusal Space, and (iv) notwithstanding anything to the contrary contained herein, the First Refusal Space shall be delivered to Tenant in its  as-is  condition on the First Refusal Commencement Date, Tenant acknowledging and agreeing that Landlord shall have no obligation to improve, remodel or otherwise alter such First Refusal Space prior to or after the First Refusal Commencement Date; provided, however, that if the First Refusal Commencement Date is after the third anniversary of the date of this Lease, then in the event the Offer provides for a tenant improvement allowance, or improvements to be completed by Landlord, then such shall be applicable to the First Refusal Space. If Tenant exercises its Right of First Refusal, the parties shall enter into an amendment to this Lease reflecting the lease by Tenant of the applicable First Refusal Space.
 
 
 36.4  In the event Tenant exercises its Right of First Refusal with respect to any First Refusal Space, then from and after the applicable First Refusal Commencement Date, the term Premises, whenever used in this Lease, shall mean the original Premises demised under this Lease and any First Refusal Space previously leased by Tenant (except, in the case of any First Refusal Space previously leased by Tenant, to the extent that the terms of this Lease are not consistent with the terms and conditions specified in the First Refusal Space Availability Notice applicable to such First Refusal Space) and the First Refusal Space then being leased (except, in the case of the First Refusal Space then being leased, to the extent that the terms of this Lease are not consistent with the terms and conditions specified in the applicable First Refusal Space Availability Notice).

In addition, during the Term and any Renewal Term, Landlord shall officially name the Building the WebEx Tower. Landlord shall use such name when referring to the Building in any marketing and advertising materials. Notwithstanding the foregoing, the rights to the Tenant Signage and to have the Building named after Tenant as provided in this Article 37 shall be personal to Original Tenant and any Permitted Transferee, but none of the rights pursuant to this Article 37 may be assigned or transferred to or exercised by any assignee, sublessee, or transferee under a Transfer unless expressly approved by Landlord, in Landlords reasonable discretion, at the time Landlord consents to such proposed transfer. In addition, if at any time Original Tenant (including any Permitted Transferee) ceases to occupy at least one hundred thousand (100,000) rentable square feet of the Leased Premises, Original Tenant shall no longer be entitled to the Rooftop Signage, the Monument Signage, or the Building naming rights provided in this Article 37.
 
 
 37.2  Signage Obligations . The installation of the Tenant Signage by Tenant shall constitute an alteration and Tenant shall comply with the requirements of this Lease for the construction of alterations with respect to the installation of such Tenant Signage. Tenant shall be responsible for all costs repair and maintain such signs. At its expense, Tenant shall remove such signs prior to the expiration or earlier termination of this Lease, and repair any damage caused to the Building in connection therewith.

If, during the Term of this Lease, Landlord shall sell its interest in the Building or the Complex of which the Leased Premises form a part, or the Leased Premises, then from and after the effective date of the sale or conveyance, Landlord shall be released and discharged from any and all obligations and responsibilities under this Lease (except those already accrued), provided that any successor pursuant to a voluntary, third-party transfer (but not as part of an involuntary transfer resulting from a foreclosure or deed in lieu thereof) shall have expressly assumed Landlords obligations under this Lease either by contractual obligation, assumption agreement or by operation of law.
 
 
 39.6  Rules and Regulations . Landlord or such other person(s) as Landlord may appoint shall have the exclusive control and management of the Common Areas and the Building and shall have the right, from time to time, to establish, modify, amend and enforce reasonable rules and regulations with respect thereto. Tenant agrees to abide by and conform to all such rules and regulations, and to cause its employees, suppliers, shippers, customers, and invitees to so abide and conform. Landlord shall not be responsible to Tenant for the non-compliance with said rules and regulations by other tenants of the Building or the Complex. Notwithstanding the foregoing, Landlord shall uniformly enforce all such rules and regulations amongst all tenants of the Building and the Complex and hereby agrees to use commercially reasonable efforts to ensure compliance with said rules and regulations by all tenants.
 
 
 39.7  Transfer to Purchaser . If any security be given by Tenant to secure the faithful performance of all or any of the covenants of this Lease on the part of Tenant, Landlord may transfer (along with its interest in this Lease and the Building) and/or deliver the security, as such, to the purchaser of the reversion, in the event that the reversion be sold, and thereupon Landlord shall be discharged from any further liability in reference thereto.
 
 
 39.8  Late Charges . Tenant acknowledges that late payment by Tenant to Landlord of rent or any other payment due hereunder will cause Landlord to incur costs not contemplated by this Lease, the exact amount of such costs being extremely difficult and impractical to fix. Such costs include, without limitation, processing and accounting charges, and late charges that may be imposed on Landlord by the terms of any encumbrance and note secured by any encumbrance covering the Leased Premises. Therefore, if any installment of rent, or any other payment due hereunder from Tenant is not received by Landlord when due after the expiration of all applicable cure periods, Tenant shall pay to Landlord an additional sum of eight percent (8%) of such rent or other charge as a late charge. The parties agree that this late charge represents a fair and reasonable estimate of the cost that Landlord will incur by reason of late payment by Tenant. Acceptance of any late charge shall not constitute a waiver of Tenant default with respect to the overdue amount, or prevent Landlord from exercising any other rights or remedies available to Landlord
 
 
 39.9  Interest . Any amount owed by Tenant to Landlord which is not paid when due shall bear interest at the lesser of ten percent (10%) per annum or the maximum rate of interest permitted to be contracted for by law. However, interest shall not be payable on late charges to be paid by Tenant under this Lease, and shall not accrue until all applicable cure periods have expired. The payment of interest on such amounts shall not excuse or cure any default by Tenant under this Lease.
 
 
 39.10  Authorization to Execute . If Tenant is a corporation, limited liability company, partnership or other entity, each individual executing this Lease on behalf of said organization represents and warrants that he is duly authorized to execute and deliver this Lease on behalf of said organization in accordance with a duly adopted resolution or other applicable authorization of said organization, and that this Lease is binding upon said organization in accordance with its terms. Further, Tenant shall, within thirty (30) days after execution of this Lease, deliver to Landlord a certified copy of a resolution or other applicable authorization of said organization authorizing or ratifying the execution of this Lease.
 
 
 39.11  Captions . The captions of this Lease are for convenience only and are not a part of this Lease and do not in any way limit or amplify the terms and provisions of this Lease.
 
 
 39.12  Number and Gender . Whenever the singular number is used in this Lease and when required by the context, the same shall include the plural, the plural shall include the singular, and the masculine gender shall include the feminine and neuter genders, and the word  person  shall include corporation, firm or association.
 
 
 39.13  Modifications . This instrument contains all of the agreements, conditions and representations made between the parties to this Lease and may not be modified orally or in any other manner than by an agreement in writing signed by all of the parties to this Lease.
 
 
 39.14  Payments . Except as otherwise expressly stated, each payment required to be made by Tenant shall be in addition to and not in substitution for other payments to be made by Tenant.
 
 
 39.15  Severability . The invalidity of any provision of this Lease, as determined by a court of competent jurisdiction, shall in no way affect the validity of any other provision hereof.
 
 
 39.16  No Offer . The preparation and submission of a draft of this Lease by either party to the other shall not constitute an offer, nor shall either party be bound to any terms of this Lease or the entirety of this Lease itself until both parties have fully executed a final document and an original signature document has been received by both parties. Until such time as described in the previous sentence, either party is free to terminate negotiations with no obligation to the other.
 
 
 39.17  Light, Air and View . If at any time any windows of the Leased Premises are temporarily darkened or covered over by reason of any repair, maintenance or restoration work, or any of such windows are permanently darkened or covered over due to any applicable governmental law or requirement or there is otherwise a diminution of light, air or view by another structure which may hereinafter be erected (whether or not by Landlord), Landlord shall not be liable for any damages and Tenant shall not be entitled to any compensation or abatement of any Rent, nor shall the same release Tenant from its obligations hereunder or constitute an actual or constructive eviction.
 
 
 39.18  Public Transportation Information . Tenant shall establish and maintain during the Term hereof a program to encourage maximum use of public transportation by personnel of Tenant employed on the Leased Premises, including, without limitation, the distribution to such employees of written materials explaining the convenience and availability of public transportation facilities adjacent or proximate to the Complex, staggering working hours of employees, and encouraging use of such facilities, all at Tenants sole reasonable cost and expense. Tenant shall comply with all requirements of any local transportation management ordinance.
 
 39.19  Joint and Several Liability . Should Tenant consist of more than one person or entity, they shall be jointly and severally liable on this Lease.
 
 
 39.20  Survival of Obligations . All obligations of Tenant which may accrue or arise during the Term of this Lease or as a result of any act or omission of Tenant during said Term shall, to the extent they have not been fully performed, satisfied or discharged, survive the expiration or termination of this Lease.
 
 
 39.21  Real Estate Brokers . Landlord agrees to pay a brokerage commission to Tenants Broker pursuant to a separate written commission agreement between Landlord and Tenants Broker, provided that in no event shall Landlord be obligated to pay a commission to Tenants Broker in connection with any extension of the Term or in connection with any additional space that is leased by Tenant pursuant to the terms of this Lease except as may be specifically provided otherwise in such written agreement or future written agreement between Landlord and Tenants Broker. Landlord and Tenant each represents and warrants to the other party that it has not authorized or employed, or acted by implication to authorize or employ, any real estate broker or salesman to act for it in connection with this Lease, except for the Broker identified in Article 1. Landlord and Tenant shall each indemnify, defend and hold the other party harmless from and against any and all claims by any real estate broker or salesman whom the indemnifying party authorized or employed, or acted by implication to authorize or employ, to act for the indemnifying party in connection with this Lease.
 
 
 39.22  Waiver of California Code Sections . In this Lease, numerous provisions have been negotiated by the parties, some of which provisions are covered by statute. Whenever a provision of this Lease and a provision of any statute or other law cover the same matter, the provisions of this Lease shall control. Therefore, Tenant waives (for itself and all persons claiming under Tenant) the provisions of Civil Code Sections 1932(2) and 1933(4) with respect to the destruction of the Leased Premises; Civil Code Sections 1941 and 1942 with respect to Landlords repair duties and Tenants right to repair; Code of Civil Procedure Section 1265.130, allowing either party to petition the Superior Court to terminate this Lease in the event of a partial taking of the Leased Premises by condemnation as herein defined; and any right of redemption or reinstatement of Tenant under any present or future case law or statutory provision (including Code of Civil Procedure Sections 473 and 1179 and Civil Code Section 3275) in the event Tenant is dispossessed from the Leased Premises for any reason. This waiver applies to future statutes enacted in addition to or in substitution for the statutes specified herein.

At any time during the Term, Landlord may require Tenant to provide Landlord with a current financial statement and financial statements of the two (2) years prior to the current financial statement year; provided, however, that Tenant shall not be required to provide such financial statements more than once every two (2) years during the Term.
 
 
 39.25  Quiet Enjoyment . So long as Tenant pays all of the Minimum Monthly Rent, all additional rent and other sums and charges under this Lease and otherwise performs all of its obligations in this Lease, Tenant shall have the right to possession and quiet enjoyment of the Leased Premises free from any unreasonable disturbance or interference, subject to the terms and provisions of this Lease. Landlord represents and warrants that it has the full right and power to execute and perform this Lease and to grant the estate demised herein.
 
 39.26  Counterparts . This Lease may be executed in one or more counterparts, each of which shall be deemed an original, but all of which when taken together shall constitute one agreement.
 
 
 39.27  Business Days . As used herein,  Business Day  means Monday through Friday of each week, exclusive of New Years Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day ( Holidays ). Landlord may designate additional Holidays, provided that the additional Holidays are commonly recognized by other office buildings in the area where the Building is located.
 
 
 39.28  Lease of Remainder of the Building . Landlord hereby agrees that, during the Term, Landlord shall not enter into any lease of space in the Building with a tenant of a type or whose proposed use would substantially interfere with the professional status of the Building or involve a quality, manner or type of business skills different than that permitted in a class A office building.

 (a)  Construction Plans. Landlord shall cause to be prepared the Construction Plans for the Tenant Improvements that are consistent with and are logical evolutions of the Preliminary Plans as soon as reasonably practicable following the mutual execution and delivery of the Lease by Landlord and Tenant. Upon completion of the Construction Plans, Landlord shall immediately forward such plans to Tenant for approval, which approval shall not be unreasonably withheld or delayed.

Landlord shall not unreasonably withhold its approval of any change requested by Tenant to the Construction Plans which does not materially delay the Estimated Commencement Date nor materially increase the cost that will be incurred by Landlord in constructing the Tenant Improvements. When the Construction Plans have been approved by Landlord and Tenant as provided above, the Construction Plans shall be initialed by the parties.
 
 
  (b)  Construction Schedule; Construction; Weekly Meetings. As soon as Construction Plans are approved in final form by the parties in accordance with the terms of subparagraph 0 above , Landlord shall cause Contractor to (i) within three (3) business days following final approval of the Construction Plans, prepare the Construction Schedule based upon such final Construction Plans, and (ii) commence and to thereafter diligently prosecute to completion the construction of the Tenant Improvements in accordance with the Construction Plans (using the standard of materials and specifications shown therein) in accordance with the Construction Schedule. The parties anticipate that the Tenant Improvements will be Substantially Completed by the Estimated Commencement Date, subject to Tenant Delays and Force Majeure Delays. Landlords Representative and Tenants Representative shall meet on a weekly basis, or more frequent basis if desired by the parties, to track the construction against the Construction Schedule and discuss the progress of construction.
 
 (c)  Subcontracts and Materials. Landlord shall cause the Contractor to competitively bid the subcontractors for the Tenant Improvements work in accordance with Landlords and Contractors standard construction practices. Landlord and Tenant hereby agree that (i) The Marshall Associates Inc. shall be the consultant hired for purposes of developing the Cafeteria, and (ii) Hayes Walker Associates shall be the consultant hired for purposes of coordinating the furniture to be used in the Leased Premises.
 
 
 (d)  Changes to Construction Plans and Construction Schedule. If, following the date that the Construction Plans have been approved by Landlord and Tenant as provided in subparagraph 0 above , Tenant desires to order extra or changed work or request that the Construction Schedule be modified (a  Change ), pursuant to a written  Change Order , Landlord shall cause Architect to prepare additional Construction Plans implementing such Change (provided, however, that Landlord shall not be required to cause Architect to implement any such Change that Landlord reasonably disapproves). Tenant shall pay the cost of preparing additional Construction Plans within ten (10) days after receipt of Landlords invoice therefor. As soon as practicable after the completion of such additional Construction Plans, Landlord shall notify Tenant of the estimated cost of the Change and the effect, if any, on the Construction Schedule. Within three (3) business days after receipt of such cost estimate, Tenant shall notify Landlord in writing whether Tenant approves the Change. If Tenant approves the Change, Landlord shall proceed with the Change and Tenant shall be liable for any excess cost resulting from the Change (and the Construction Schedule shall be modified to reflect any adjustments attributable to such Change). For purposes of the preceding sentence, excess cost means any cost attributable to the Change that are in excess of the costs that would have been incurred by Landlord in connection with the construction of the Tenant Improvements if such Change had not been made. If Tenant fails to approve the Change within such three (3) business day period, construction of the Tenant Improvements shall proceed as provided in accordance with the original Construction Documents.
 
 All Change Orders shall be billed on a cost plus fee basis unless otherwise agreed by Tenant, with the Contractors fee thereon not to exceed three percent (3%) and the subcontractors fee not to exceed fifteen percent (15%). Tenant shall not be responsible for the payment of any general condition charges or general requirement charges (the  General Condition Charges

Tenant shall conform to the Buildings wiring standards in installing any telephone equipment and shall be subject to any and all rules of the site during construction.
 
 (f)  Disapprovals and Failures to Respond. Any disapproval by Tenant or Landlord of the Construction Plans submitted for its approval shall be communicated only by a writing, which shall be delivered to the other party within the time permitted hereunder. Such notice shall specify the disapproved item(s), the reason(s) for the disapproval, and the changes required to make the item acceptable to such party.
 
 (g)  Standard of Construction. Landlord shall obtain from Contractor, and cause Contractor to obtain from each subcontractor for the express benefit of Landlord and Tenant, a warranty that the Tenant Improvements have been constructed in accordance with the Construction Plans and Applicable Laws and in a good and workmanlike manner, and that they shall be free from defects in material and workmanship. Such warranty(ies) shall be effective for a minimum of one (1) year following completion of the Tenant Improvements (collectively, the  Warranties ) and shall be expressly assignable to Tenant, provided that Landlord, at its option, shall either pursue such claims directly or assign any such Warranties to Tenant for enforcement.
 
 5. Payment of Construction Costs .
 
 (a)  Landlord shall apply for all permits required in connection with the construction of the Tenant Improvements described on the Preliminary Plans and shall pay all fees related to such permits and all costs to construct the Tenant Improvements described on the Preliminary Plans (except as set forth in Sections 0 and 0 of this Work Letter), including, without limitation, costs incurred in the preparation of the Preliminary Plans and Construction Plans. Notwithstanding anything herein to the contrary, Tenant shall reimburse Landlord for the costs of all permits required in connection with the substantial completion of the Cafeteria and Fitness Center (excluding the Cafeteria Improvements and Fitness Center Improvements).

The balance, if any, of the total cost of the improvements to be installed in the Cafeteria over the Cafeteria Allowance and the cost of constructing the Cafeteria Improvements, shall be paid by Tenant. Tenant shall be responsible for the cost of fitness equipment to be used in the Fitness Center, as well as the cost of any improvements to the Fitness Center that exceed the cost of constructing the Fitness Center Improvements. The procedure for requesting and implementing improvements to the Cafeteria and Fitness Center, other than the Cafeteria Improvements and the Fitness Center Improvements, and the procedure for payment by Tenant of costs therefor shall be in accordance with the Change Order process described in Section 0 above .

 7.  Tenant Fixturing . Landlord shall use all reasonable efforts to complete construction of Tenant Improvements to a point permitting Tenants entry for installation of its fixtures and equipment on or before the Commencement Date.

Landlord shall use commercially reasonable efforts to provide such early entry to Tenant at least thirty (30) days prior to the Commencement Date. Landlord and Tenant shall cooperate in good faith to schedule and coordinate Tenants fixturing with Landlords construction in a manner which will not interfere with Substantial Completion of the Tenant Improvements by the Estimated Commencement Date, will minimize any increase in each partys cost, and will ensure labor harmony. While performing fixturing, Tenant shall comply, and shall cause its employees, contractors and suppliers to comply, with the reasonable work rules observed by Landlords Contractor.
 
 8.  Inspection & Punchlist . Tenants Representative and consultants shall have the right to enter on the Leased Premises at all reasonable times and upon reasonable prior notice to Landlords Representative for the purpose of inspecting the progress of the work. Tenants Representative, Landlords Representative and the Architect(s), and such advisers as they shall desire, shall inspect the Leased Premises within fifteen (15) days after Substantial Completion using commercially reasonable efforts to discover all uncompleted or defective construction. If Tenant fails to participate in the preparation of a punch list with Landlord within such fifteen (15) day period, Tenant agrees that by taking possession of the Leased Premises it will conclusively be deemed to have inspected the Leased Premises and found the Leased Premises in satisfactory condition, with all work required of Landlord completed. After such inspection has been completed, a list of punchlist items shall be prepared jointly by Landlord and Tenant which the parties agree are to be corrected by Landlord. Landlord shall use its commercially reasonable efforts to complete and/or repair such punchlist items within thirty (30) days. Tenant acknowledges that neither Landlord, nor any agent, employee or servant of Landlord, has made any representation or warranty, expressed or implied, with respect to the Leased Premises, the Building or the Common Areas of the Complex, or with respect to the suitability of them to the conduct of Tenants business, nor has Landlord agreed to undertake any modifications, alterations, or improvements of the Leased Premises, the Building or the Common Areas of the Complex, except as specifically provided in this Lease.
 
 9.  Indemnification . Landlord covenants to timely pay the costs of the Tenant Improvements and the Cafeteria Allowance as set forth herein.

Without affecting the foregoing subordination, Lender may, from time to time: (a) extend, in whole or in part, by renewal or otherwise, the terms of payment or performance of any obligation secured by the Security Instrument; (b) release, surrender, exchange or modify any obligation secured by the Security Instrument, or any security for such obligation; or (c) settle or compromise any claim with respect to any obligation secured by the Security Instrument or against any person who has given security for any such obligation.
 
 
 2.  Non-Disturbance and Attornment . If, at any time, Lender or any person or entity or any of their successors or assigns who shall acquire the interest of Landlord under the Lease through a foreclosure of the Security Instrument, the exercise of the power of sale under the Security Instrument, a deed-in-lieu of foreclosure, an assignment-in-lieu of foreclosure or otherwise (each, a  New Owner ) shall succeed to the interests of Landlord under the Lease, so long as the Lease is then in full force and effect, and no default after the giving of any required notice, and expiration of any applicable grace period, under the Lease (a  Default ) on the part of Tenant exists under the Lease (and provided the Lease has not previously been terminated in accordance with its terms) , the Lease shall continue in full force and effect as a direct lease between the New Owner and Tenant, upon and subject to all of the terms, covenants and conditions of the Lease, for the balance of the term thereof. Tenant hereby agrees to attorn to and accept any such New Owner as landlord under the Lease and to be bound by and perform all of the obligations imposed by the Lease, and Lender, or any such New Owner of the Property, agrees that it will not disturb the quiet enjoyment, possession , use or occupancy of Tenant and will be bound by all of the obligations imposed on Landlord by the Lease; provided, however, that any New Owner shall not be:
 
 (a)  liable for damages for any act or omission of a prior landlord (including Landlord) arising prior to the date upon which the New Owner shall succeed to the interests of Landlord under the Lease; provided, however, that the New Owner shall be obligated to cure promptly any maintenance or repair obligations which Landlord failed to cure; or
 
 (b)  subject to any claims, offsets or defenses (other than rental abatement arising from loss by casualty or condemnation as expressly allowed under the Lease) which Tenant might have against any prior landlord (including Landlord) arising prior to the date upon which the New Owner shall succeed to the interests of Landlord under the Lease , except to the extent Tenant is entitled to same under the express terms of the Lease and the New Owner was furnished notice and opportunity to cure the same in accordance with the provisions of this Agreement prior to taking possession of the Property ; or
 
 (c)  bound by any rent or additional rent which Tenant might have paid in advance to any prior landlord (including Landlord) for a period in excess of one (1) month or bound to return any security deposit which Tenant might have paid in advance to any prior landlord (including Landlord), except to the extent that such New Owner actually has possession of the same; if Lender or a New Owner draws upon any letter of credit security deposit, Tenant shall have no claim for damages in connection therewith (and waives any such claim), but Tenant shall have the right to recover any amounts wrongfully drawn (in addition to any amounts which Tenant may be entitled to recover under Section 0 below and any actual interest, charges or fees charged by the issuer of such letter of credit security deposit to Tenant in connection with such wrongful draw); or
 
 (d)  bound by any termination, material amendment or material modification of the Lease made without the written consent of Lender , provided that nothing herein shall limit any express right of Tenant to terminate the Lease as contained therein.
 
 
  3.  Cure by Lender of Landlord Defaults . Tenant hereby agrees that from and after the date hereof, in the event of any default by Landlord which would give Tenant the right, either immediately or after the lapse of time, to terminate or cancel the Lease or to claim a partial or total eviction, Tenant will not exercise any such right until it has given written notice of such act or omission to Lender, and Lender has failed to cure such default within the longer of (x) any time provided for such cure in the Lease and (y) thirty (30) days after receipt of such notice by Lender.
 
 4.  Payments to Lender and Exculpation of Tenant . Tenant is hereby notified that the Lease and the rent and all other sums due thereunder have been assigned to Lender as security for the Loan. In the event that Lender or any future party to whom Lender may assign the Security Instrument notifies Tenant and directs that Tenant pay its rent and all other sums due under the Lease to Lender, to such assignee, or to another designee, Tenant shall honor such direction without inquiry and pay its rent and all other sums due under the Lease in accordance with such notice. Landlord agrees that Tenant shall have the right to rely on any such notice from Lender or any such assignee without incurring any obligation or liability to Landlord, and Tenant is hereby instructed to disregard any notice to the contrary received from Landlord or any third party.
 
 5.  Limitation of Liability . Lender shall not, either by virtue of the Security Instrument, the Assignment of Leases or this Agreement, be or become a mortgagee-in-possession or be or become subject to any liability or obligation under the Lease or otherwise unless and until Lender shall have acquired the interest of Landlord in the Leased Premises, by foreclosure or otherwise, and then such liability or obligation of Lender under the Lease shall (subject to Section 0 above ) extend only to those liabilities or obligations accruing subsequent to the date that Lender has acquired the interest of Landlord in the Leased Premises as modified by the terms of this Agreement. In addition, upon such acquisition, Lender shall have no obligation, nor incur any liability, beyond Lenders then equity interest, if any, in the Leased Premises.
 
 6.  Notice . Any notice, demand, statement, request, consent or other communication made hereunder shall be in writing and delivered (i) personally, (ii) mailed by certified or registered mail, postage prepaid, return receipt requested or (iii) by depositing the same with a reputable private courier service, postage prepaid, for next business day delivery, to the parties at their addresses first set forth above and shall be deemed given when delivered personally, or four (4) business days after being placed in the United States mail, if sent by certified or registered mail, or one (1) business day after deposit with such private courier service. Rejection or other refusal to accept or the inability to deliver because of changed address of which no notice was given as herein required shall be deemed to be receipt of the notice, demand or request sent. By giving to the other parties thereto at least fifteen (15) days prior written notice hereof in accordance with the provisions hereof, the parties hereto shall have the right from time to time to change their respective addresses to any other address within the United States of America. Tenant agrees to send a copy of any notice of default under the Lease to Lender at the same time such notice is sent to Landlord.
 
 
 7.  Landlords Release . Landlord hereby releases Tenant from all claims, losses and liabilities arising from Tenants payment of rent and other sums to Lender following Tenants receipt of written notice directing Tenant to make such payments to Lender. All such payments made by Tenant to Lender shall be credited to installments of rent otherwise payable to Landlord under the Lease.
 
 
 8.  Tenants Property Unaffected . Neither the Security Instrument, the assignment of leases, nor any other instrument or agreement executed in connection therewith shall cover or be construed as subjecting in any manner to the lien thereof, any merchandise, goods, improvements, trade fixtures, signs or other personal property owned by Tenant or its subtenants or licensees in, on, under, over or at the Leased Premises regardless of the manner or mode of attachment thereof.
 
 
 9.  Statements by Lender . Lender hereby advises Tenant that (a) Lender is the beneficiary of the Security Instrument and the holder of any other documents evidencing, securing or relating to the Loan, and (b) such agreements have not been transferred, pledged or assigned by Lender.
 
 
 10.  Cooperation . Within fifteen (15) days following Lenders receipt of any proposed written amendment or modification to the Lease, Lender shall either (a) grant such consent or, subject to the other terms and conditions hereof, or (b) advise Landlord and Tenant of the basis for Lenders reasonable denial of such consent. If the transmittal letter to Lender accompanying such amendment or modification states in capital letters that such amendment or modification will be deemed approved by Lender if Lender fails to approve or disapprove such amendment or modification within fifteen (15) days, and if within such fifteen (15) day period Lender fails to advise Landlord and Tenant of Lenders decision either to grant or to withhold its consent to any such amendment or modification, then Lender shall be deemed to have approved such amendment or modification and, should Lender or another party complete the foreclosure or other acquisition of the Leased Premises or the Property, Lender or such other party shall be bound by the terms thereof.
 
 11. Miscellaneous .
 
 (a) In the event of any conflict or inconsistency between the provisions of this Agreement and the Lease, the provisions of this Agreement shall govern; provided, however, that the foregoing shall in no way diminish Landlords obligations or liability to Tenant under the Lease .
 
 (b) Tenant agrees that this Agreement satisfies any condition or requirement in the Lease relating to the granting of a non-disturbance agreement.
 
 (c) Tenant agrees that it will not subordinate the Lease to the lien of any mortgage or deed of trust other than the Security Instrument for so long as the Security Instrument shall remain a lien on the Property. Landlord agrees that notwithstanding any provision of the Lease to the contrary, Tenant shall not be required to subordinate Tenants rights under the Lease to any other party so long as the Security Instrument shall remain a lien on the Property. Landlord shall provide Tenant with written documentation evidencing the release and reconveyance of the Security Instrument promptly following such release and reconveyance.
 
 (d) This Agreement shall inure to the benefit of the parties hereto and their respective successors and assigns .
 
 (e) The captions appearing under the paragraph number designations of this Agreement are for convenience only and are not a part of this Agreement and do not in any way limit or amplify the terms and provisions of this Agreement.
 
 (f) If any portion or portions of this Agreement shall be held invalid or inoperative, then all of the remaining portions shall remain in full force and effect, and, so far as is reasonable and possible, effect shall be given to the intent manifested by the portion or portions held to be invalid or inoperative.
 
 (g)  This Agreement shall be governed by and construed in accordance with the laws of the State in which the Property is located.
 
 (h)  This Agreement may be executed in any number of separate counterparts, each of which shall be deemed an original, but all of which, collectively and separately, shall constitute one and the same agreement.
 
 
 (i)  This Agreement cannot be altered, modified, amended, waived, extended, changed, discharged or terminated orally or by any act on the part of Tenant, Landlord or Lender, but only by an agreement in writing signed by the party against whom enforcement of any alteration, modified, amendment, waiver, extension, change, discharge or termination is sought.
 
 
 (j)  In the event of litigation between any of the parties hereto, the prevailing party shall be entitled to collect its reasonable attorneys fees and expenses from the non-prevailing party.
