Any provision in this Lease that one party or the other party or both shall do or not do or shall cause or permit or not cause or permit a particular act, condition or circumstance shall be deemed to mean that such party so covenants or both parties so covenant, as the case may be.

(m) Whenever this Lease provides that Tenant shall indemnify the Landlord, such provision shall be deemed to mean that Tenant shall indemnify, defend and hold harmless Landlord in accordance with Article 14.

2. PREMISES

2.1 Premises. Subject to the terms, covenants and conditions set forth in this Lease, Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the premises (the “Premises”) consisting of the buildings shown on Exhibit A-1 and identified in Article 1 (the “Buildings”). The approximate total Rentable Area of the Premises and the Buildings are specified in Article 1. Together, the Buildings, any other buildings located in the vicinity of the Buildings on the land described on Exhibit A-2 and operated as a common project with the Buildings, and the Common Area for the joint operation of the Building and such other buildings, are referred to as the “Property”.

2.2 Common Area. Landlord hereby grants to Tenant and its employees, agents, contractors and invitees (collectively, “Tenant’s Agents”) a non-exclusive license in common with other tenants of the Property to use the Common Area during the Term. Tenant’s rights to the Common Area shall be subject to the Rules and Regulations described in Section 24.1 and to Landlord’s reserved rights described in Article 17.

2.3 Parking. Landlord hereby grants to Tenant and Tenant’s Agents a non-exclusive license in common with other tenants of the Property to use parking areas located on the Property for parking and for ingress to and egress from the Property. Tenant’s license shall not be assigned, sublet or otherwise transferred separately from the Premises. Tenant agrees that neither Tenant nor Tenant’s Agents shall use parking spaces in areas not designated for Tenant’s use. Landlord shall have the right, at Landlord’s sole discretion (but subject to any covenants or restrictions encumbering the Property), to specifically designate the location of Tenant’s parking spaces (if any) within the parking areas of the Common Area. Tenant’s parking spaces (if any) may be relocated by Landlord from time to time upon written notice. Tenant shall not, at any time, park, or permit the parking of the trucks or vehicles of Tenant or Tenant’s Agents in any portion of the Common Area not designated by Landlord for such use by Tenant. So long as Tenant leases 100% of the Premises leased by Tenant hereunder as of the Commencement Date, all parking areas located on the Property (if any) shall be available for Tenant’s use, provided that Landlord and its agents may also use the parking areas in connection with the performance of its obligations or exercise of its rights under this Lease. If at any time during the Term, the Premises leased by Tenant hereunder shall be less than 100% of the Premises leased by Tenant as of the Commencement Date, so that a portion of the Buildings shall be available to Landlord to lease to others, Tenant’s right to use parking shall be limited to Tenant’s Share of parking. Tenant shall not park nor permit to be parked any inoperative vehicles or store any materials or equipment on any portion of the parking area or other areas of the Common Area. Tenant agrees to assume responsibility for compliance by Tenant’s Agents with the parking provisions contained in this Section. Tenant hereby authorizes Landlord at Tenant’s expense to attach violation stickers or notices to such vehicles not parked in compliance with this Section and to tow away any such vehicles. In addition, a specific section of the parking area may be set aside by Landlord for visitor parking for the Property.

3. TERM

3.1 Term. The Premises are leased for a term (the “Term”) commencing on the Commencement Date and expiring on the Expiration Date. The Term shall end on the Expiration Date, or such earlier date on which this Lease terminates pursuant to its terms. The date upon which this Lease actually terminates, whether by expiration of the Term or in the event of default or surrender of the Premises is sometimes referred to in this Lease as the “Termination Date”.

3.2 Renewal Option. Tenant shall have two (2) options (the “Renewal Options”) to extend the Term for a period of five (5) years (each, a “Renewal Term”, and respectively the “First Renewal Term” and the “Second Renewal Term”). Each Renewal Term (i) must be exercised, if at all, as to the entire Premises subject to this Lease as of the Commencement Date (unless reduced pursuant to condemnation) and (ii) will be void if this Lease has previously expired or terminated with respect to any part of the Premises leased by Tenant hereunder as of the Commencement Date (other than as a result of condemnation), or if the Premises then leased by Tenant hereunder shall be less than 100% of the Premises as of the Commencement Date such that a portion of the Buildings shall be available to Landlord to lease to others. Each Renewal Option shall be void if an Event of Default by Tenant exists, either at the time of exercise of the applicable Renewal Option or the time of commencement of the applicable Renewal Term. Each Renewal Option must be exercised, if at all, by written notice from Tenant to Landlord given not less than twelve (12) months prior to the expiration of the Term (in the case of the First Renewal Term), and not less than twelve (12) months prior to the expiration of the First Renewal Term (in the case of the Second Renewal Term). For the avoidance of doubt, the Second Renewal Term shall be void unless the First Renewal Option shall be timely exercised by Tenant. Each Renewal Term shall be upon the same terms and conditions as the original Term, except that the Base Rent applicable to the relevant Renewal Term shall be equal to the greater of (i) Base Rent payable under this Lease for the full year immediately preceding the effectiveness of that Renewal Term or (ii) Prevailing Market Rent as of the commencement of that Renewal Term, as determined pursuant to Exhibit C. As a condition to the exercise and the effectiveness of the Renewal Option, Tenant shall be required to modify the Letter of Credit so that the Letter of Credit will have a face amount equal to the Required Amount and otherwise meet the requirements of Section 4.7 with respect to the Term as extended by Tenant’s exercise of the Renewal Option. The Renewal Option is personal to Tenant and shall be inapplicable and null and void if Tenant assigns its interest under this Lease (including an “Assignment” as defined in Section 15.1 but excluding short-term Subleases contemplated by Section 15.5).

4. RENT

4.1 Net Lease—Net Rent. It is the purpose and intent of Landlord and Tenant that, except as expressly provided otherwise herein, this Lease shall be deemed and construed to be a so-called “triple net lease” and that the Base Rent and Additional Rent shall be absolutely

net to Landlord throughout the Term, so that this Lease shall yield, absolutely net to Landlord, the Base Rent and Additional Rent throughout the Term, free of any charges, assessments, impositions, Real Estate Taxes or deductions of any kind charged, assessed or imposed on or against the Premises and without abatement, deduction, deferment, reduction, defense, credit, set-off or counterclaim (except as may otherwise be expressly provided herein) whatsoever by Tenant, and Landlord shall not under any circumstances or conditions, whether now existing or hereafter arising, or whether beyond the present contemplation of the parties, be expected or required to pay any such charge, assessment, imposition, Real Estate Tax or deduction, or be under any obligation or liability hereunder except as expressly otherwise provided herein. It is agreed that except as expressly otherwise provided herein all costs, expenses and charges of every kind and nature whatsoever relating to the Premises, or the use, operation or maintenance thereof, which may arise or become due during the Term of this Lease, including, without limitation, those relating to the maintenance, preservation, care, repair and operation of the Premises (including, without limitation, all costs, expenses and charges for water, sewer, natural gas, electricity, telephone and any other utility used upon or furnished to the Premises) and all restorations, replacements, Alterations and additions in and to the Premises as herein provided shall be paid and/or performed by Tenant, at Tenant’s sole cost and expense, and Landlord shall be indemnified and saved harmless by Tenant from and against the same.

4.2 Base Rent. Commencing upon the Commencement Date, and thereafter during the Term, Base Rent will be payable in monthly installments in advance on or before the first day of each month at the rate of one-twelfth (1/12) of the annual Base Rent specified in Article 1. After the Letter of Credit is deposited hereunder, Landlord will, on or after the first day of each calendar month or the immediately preceding Business Day if the first day of a month is not a Business Day, draw upon the Letter of Credit each month for payment of monthly Base Rent then due. If Landlord notifies Tenant that Landlord does not intend or is unable to draw on the Letter of Credit, Tenant shall pay the Base Rent due to Landlord by wire transfer of immediately available funds, to Landlord’s account specified in writing to Tenant, without any prior notice or demand and without any deductions or setoff whatsoever, other than as expressly provided herein. If the Commencement Date occurs on a day other than the first day of a calendar month, or the Termination Date occurs on a day other than the last day of a calendar month, then the Base Rent for such fractional month will be prorated on the basis of the actual number of days in such month. The Rentable Area of the Premises and the Buildings shall be conclusively presumed to be as stated in Article 1, and shall not be subject to adjustment by either Landlord or Tenant during the Term, other than as described herein.

4.3 Rent Adjustment. Commencing on January 1, 2002 and every January 1 thereafter (each, an “Adjustment Date”), the Base Rent shall be increased as stated in Article 1.

4.4 Additional Rent. All sums due from Tenant to Landlord or to any third party under the terms of this Lease shall be additional rent (“Additional Rent”), including without limitation the charges for Base Rent and Operating Expenses (described in

Article 5) and all sums incurred by Landlord due to Tenant’s failure to perform its obligations under this Lease. In accordance with Section 5.1, so long as Tenant leases 100% of the Premises leased by Tenant hereunder as of the Commencement Date, Tenant shall pay directly to the person entitled thereto all Operating Expenses except those identified in clauses (i), (ii) and (ix) of Section 5.1(b), which Landlord shall pay directly and shall pass through to Tenant as Additional Rent payable in monthly installments in advance equal to one-twelfth (1/12) of the annual amount thereof. All Additional Rent which is payable to Landlord shall be paid at the time and place that Base Rent is paid. For the avoidance of doubt, Landlord will draw upon the Letter of Credit each month on the same day that Base Rent is drawn an amount equal to the Additional Rent then due, provided that if Landlord delivers the notice described in Section 4.2, Tenant shall pay the Additional Rent to Landlord in the same manner as Base Rent. Landlord will have the same remedies for a default in the payment of any Additional Rent as for a default in the payment of Base Rent. Together, Base Rent and Additional Rent are sometimes referred to in this Lease as “Rent”. There shall be no abatement of, deduction from, counterclaim or setoff against Rent except as otherwise specifically provided in this Lease.

4.5 Late Payment. Any unpaid Rent shall bear interest from the date due until paid at the lesser of (i) fifteen percent (15%) per annum or (ii) the maximum interest rate allowed by law (the “Interest Rate”). In addition, Tenant recognizes that late payment of any Rent will result in administrative expense to Landlord, the extent of which expense is difficult and economically impracticable to determine. Therefore, Tenant agrees that if Tenant fails to pay any Rent within five (5) days after its due date, an additional late charge of seven percent (7%) of the sums so overdue shall become immediately due and payable. Tenant agrees that the late payment charge is a reasonable estimate of the additional administrative costs and detriment that will be incurred by Landlord as a result of such failure by Tenant. In the event of nonpayment of interest or late charges on overdue Rent, Landlord shall have, in addition to all other rights and remedies, the rights and remedies provided in this Lease and by law for nonpayment of rent.

4.6 Covenant. Tenant covenants to pay (a) Rent when due and (b) observe and perform and not to suffer or permit any violation of Tenant’s obligations under this Lease.

4.7 Credit Enhancement

(a) On or before February 15, 2001, Tenant shall deliver to Landlord a Letter of Credit as security for the full and punctual performance by Tenant of all of the terms of this Lease. If the Letter of Credit is not timely delivered, in accordance with Section 2.2(a) of the Purchase Agreement, Landlord will retain a portion of the Purchase Price (as defined in the Purchase Agreement), and Tenant shall have no further obligation to deliver the Letter of Credit. For so long as the Letter of Credit is in effect and sufficient funds thereunder shall be available for draw, Landlord shall be entitled to draw such Letter of Credit each month for payment of Base Rent and Additional Rent. In addition, if Landlord

shall be entitled to draw the Letter of Credit in whole or in part pursuant to the other provisions of this Lease, Landlord shall have the right, at its option, either to deposit the cash proceeds of any such draw upon the Letter of Credit into a cash collateral account (the “Cash Collateral Account”) established in Landlord’s name and maintained by Landlord or to apply the proceeds to the obligations of Tenant due or to become due hereunder. The Cash Collateral Account shall be under the sole dominion and control of Landlord and Landlord shall have the sole right to make withdrawals from the Cash Collateral Account and to exercise all rights with respect to the amounts deposited in the Cash Collateral Account.

(b) The initial letter of credit and any replacement letter of credit issued to Landlord shall satisfy the requirements set forth in this Section 4.7 (each, a “Letter of Credit”). Each Letter of Credit shall be a clean, irrevocable, non-documentary and unconditional letter of credit issued by and drawable upon any commercial bank, trust company, national banking association or savings and loan association with offices for banking and drawing purposes in the City of San Francisco (the “Issuing Bank”), which has outstanding, unsecured, uninsured and unguaranteed indebtedness, or shall have issued a letter of credit or other credit facility that constitutes the primary security for an outstanding indebtedness (which is otherwise uninsured and unguaranteed), that is then rated, without regard to qualification of such rating by symbols such as “+” or “-” or numerical notation, “A” or better by Xxxxx’x Investment Service and “A” or better by Standard & Poor’s Ratings Service (and is not on credit-watch or similar credit review with negative implication), and has combined capital, surplus and undivided profits of not less than $1,000,000,000. Each Letter of Credit shall (i) name Landlord as beneficiary, (ii) be in the amount of the Required Amount, (iii) have a term of not less than one (1) year, (iv) permit multiple drawings, (v) be fully transferable by Landlord without payment of any fees or charges, (vi) at Landlord’s request, name any Leasehold Mortgagee as a co-beneficiary and (vii) otherwise be in form and content satisfactory to Landlord in its sole discretion. If upon the transfer of any Letter of Credit, any fees or charges shall so be imposed, then such fees or charges shall be payable solely by Tenant and the Letter of Credit shall so specify. Regardless of the initial expiration date of any Letter of Credit, each Letter of Credit shall expressly provide that (unless notice of non-renewal is delivered in accordance with the following sentence) it shall be deemed automatically renewed, without amendment, for consecutive periods after such expiration date of one year each during the Term through the date that is at least one hundred eighty (180) days after the Expiration Date. If the Issuing Bank desires not to renew a Letter of Credit, it shall deliver a notice (the “Non-Renewal Notice”) to Landlord by certified mail, return receipt requested, not less than sixty (60) days prior to the then-current expiration date of the Letter of Credit, stating that the Issuing Bank has elected not to renew the Letter of Credit. In such event or if (a) for any other reason the Letter of Credit would expire by its terms in sixty (60) days or less from such date or (b) the Issuing Bank is downgraded so that it no longer satisfies the rating requirements set forth in this Section 4.7, Landlord shall have the right, at its option, either (x) to draw the full amount of the Letter of Credit, by sight draft on the Issuing Bank, and thereafter hold the proceeds in the Cash Collateral Account and apply them pursuant to the terms of this Article 4, or (y) to require Tenant to procure, or Landlord to procure on Tenant’s behalf at Tenant’s cost and

utilizing if necessary the cash proceeds so drawn, a replacement Letter of Credit that satisfies the requirements of this Section 4.7; provided that Landlord shall provide Tenant with notice of any such event at least ten (10) business days before exercising such rights and Tenant may, within ten (10) business days after such notice is provided, deliver a replacement Letter of Credit that satisfies the requirements of this Section 4.7, and provided further that such notice shall not be required in the event Landlord determines in good faith that the delay caused by providing such notice presents a risk that Landlord will not be able to exercise its rights to draw upon the Letter of Credit following such delay. Each Letter of Credit shall be governed by the International Standby Practices-ISP98 or any standard set of practices replacing ISP98. Each Letter of Credit shall be substantially in the form attached hereto as Exhibit D.

(c) Within three (3) business days following any draw under the Letter of Credit or such shorter period as may be required under the Tenant’s reimbursement agreement with the Issuing Bank, Tenant shall reimburse the Issuing Bank for each such draw in an amount sufficient to insure that the face value of the Letter of Credit is an amount at least equal to the Required Amount and shall cause the Issuing Bank to provide written notice to Landlord if such reimbursement is not timely made. In addition, if the Base Rent or Additional Rent increases such that the Required Amount would increase, Tenant shall within five (5) business days after such increase cause the Letter of Credit to be modified so that it satisfies the requirements of this Section 4.7. In the event Tenant fails to timely reimburse the Letter of Credit bank or increase the face amount of the Letter of Credit as required, such failure shall constitute an Event of Default hereunder, and, in addition to all other rights and remedies available to Landlord for Tenant’s default, Landlord shall have the right to draw the full amount of the Letter of Credit, by sight draft on the Issuing Bank, and shall thereafter hold in the Cash Collateral Account or apply the cash proceeds of the Letter of Credit pursuant to the terms of this Article 4.

(d) In addition to the foregoing, if an Event of Default occurs under this Lease, Landlord may draw the full amount of the Letter of Credit, by sight draft on the Issuing Bank, and thereupon receive all or a portion of the face amount of the Letter of Credit, and use, apply or retain the whole or any part of such proceeds, as the case may be, to the extent required for the payment of any Base Rent, Additional Rent or other amounts due or to become due hereunder or for any reasonable sum which Landlord may expend or may be required to expend by reason of Tenant’s default in respect of any of the terms of this Lease, including any damages or deficiency in the re-letting of the Premises, whether accruing before or after summary proceedings or other re-entry by Landlord. In the event Landlord obtains an arbitration award or judicial determination entitling Landlord to indemnification or monetary damages under the Purchase Agreements or the Ground Lease Assignments, Landlord may draw upon the full amount of the Letter of Credit, by sight draft on the Issuing Bank, and thereupon receive all or a portion of the face amount of the Letter of Credit, in an amount equal to the amount which Landlord is so entitled under the Purchase Agreements or Ground Lease Assignments. In the case of every such use, application or retention, Tenant shall, within three (3) business days following any such use, application or

retention or such shorter period as may be required under the Tenant’s reimbursement agreement with the Issuing Bank, cause the face value of the Letter of Credit to be restored to the Required Amount, and Tenant shall cause the Issuing Bank to acknowledge to Landlord that such restoration of the Required Amount occurred in a timely manner. Notwithstanding the foregoing, if Tenant is not in default under this Lease, during the last twelve (12) months of the Term (including any extension thereof pursuant to a Renewal Option exercised by Tenant), the amount of the Letter of Credit may be decreased to the sum of the amount of Base Rent payable over the last twelve (12) months of the Term plus the amount of Additional Rent payable for the most recent calendar year, provided that it shall be a condition to the exercise of any Renewal Option that Tenant cause a Letter of Credit to be issued in the full amount of the Required Amount (or, if Section 4.7(e) applies, the Reduced Amount). If Tenant shall fully and punctually comply with all of the terms of this Lease, the Letter of Credit shall be terminated, as applicable, within one hundred eighty (180) days after the termination of this Lease and delivery of exclusive possession of the Premises to Landlord.

(e) In the event Tenant has outstanding, unsecured, uninsured and unguaranteed indebtedness that becomes rated, without regard to qualification of such rating by symbols such as “+” or “-” or numerical notation, “A” or better by Xxxxx’x Investment Service and “A” or better by Standard & Poor’s Ratings Service (and is not on credit-watch, or similar credit review with negative implication), at Tenant’s request, if Tenant is not in default hereunder, Landlord will permit the face amount of the Letter of Credit to be reduced to an amount equal to the Reduced Amount. If Landlord agrees to reduce the Required Amount pursuant to this Subsection (e), Tenant shall not be permitted to let the face amount of the Letter of Credit be reduced during the last twelve (12) months of the Term pursuant to paragraph (f) above, it being understand[sic] that in no event shall the face amount of the Letter of Credit be less than the Reduced Amount. If at any time Tenant ceases to maintain the ratings specified in the first sentence of this Section 4.7(e), then the face amount of the Letter of Credit shall be increased to the Required Amount.

(f) In the event of a transfer of the Buildings or the Property, Landlord shall have the right to transfer the Letter of Credit or Cash Collateral to the transferee and upon such transfer to such transferee, Landlord shall ipso facto be released by Tenant from all liability for the return of the Letter of Credit or Cash Collateral; provided the transferee agrees to assume Landlord’s obligation to return the Letter of Credit or Cash Collateral; and Tenant agrees to look solely to the new landlord for the return of said Letter of Credit or Cash Collateral; and it is agreed that the provisions hereof shall apply to every transfer or assignment made of the Letter of Credit or Cash Collateral to a new landlord. Tenant shall promptly execute such documents reasonably requested by Landlord as may be necessary to accomplish any such transfer or assignment of the Letter of Credit or Cash Collateral. Tenant shall not assign or encumber or attempt to assign or encumber the Letter of Credit or Cash Collateral and neither Landlord nor its successors or assigns shall be bound by any such assignment, encumbrance or attempted assignment or encumbrance. Upon ten (10) days prior written notice from Landlord, Tenant will cause any Letter of Credit to be

modified so that it names any Leasehold Mortgagee as a co-beneficiary under the Letter of Credit.

4.8 Legal Requirements

If any of the Rent payable under the terms of this Lease shall be or become uncollectible, reduced or required to be refunded because of any Legal Requirement, Tenant shall enter into such agreements and take such other steps as Landlord may reasonably request and as may be legally permissible, to permit Landlord to collect the maximum rents which from time to time during the continuance of such legal rent restriction may be legally permissible. Upon the termination of such legal rent restriction, (a) the rents shall become and thereafter be payable in accordance with the amounts reserved herein for the periods following such termination and (b) Tenant shall pay to Landlord, to the maximum amount legally permissible, an amount equal to, (i) the rents which would have been paid pursuant to this Lease but for such legal restriction, less (ii) the rents and payments in lieu of rents paid by Tenant during the period such legal restriction was in effect.

5. OPERATING EXPENSES

5.1 Operating Expenses. For purposes of this Article 5, the following terms shall have the meanings described below:

(a) “Tenant’s Share” means 100% for the period commencing with the Commencement Date and ending on the date the Premises leased by Tenant hereunder shall be less than 100% of the Premises leased by Tenant hereunder as of the Commencement Date, so that a portion of the Buildings shall be available to Landlord to lease to others. In such event, Tenant’s Share shall be reduced to the proportionate share of the Rentable Area then leased by Tenant at the Buildings. The parties hereto acknowledge that Tenant’s Share is based upon an assumption that the entire Buildings contain a total of 482,950 square feet of Rentable Area, and the calculation of Tenant’s Share is based upon a fraction the denominator of which is 482,950.

(b) “Operating Expenses” means the total costs and expenses paid or incurred in connection with the ownership, management, operation, maintenance, repair and replacement of the Buildings and the Common Area, including, without limitation, all costs of:

(i) rent and other payments (including escalations) due to the City of Mountain View from Landlord, as tenant under that certain Ground Lease (the “Ground Lease”) dated March 7, 1995 with respect to the Property as the same may be amended from time to time;

(ii) taxes, assessments and charges levied upon or with respect to the Property or any personal property of Landlord used in the operation of the Property, or on Landlord’s interest in the Property or such personal property (“Real Estate

Real Estate Taxes shall not include franchise, transfer, succession, gift, inheritance, gross receipts or capital stock taxes or income taxes measured by the net income of Landlord unless, due to a change in the method of taxation, any of such taxes is levied or assessed against Landlord as a substitute for, or as an addition to, in whole or in part, any other tax that would otherwise constitute a Real Estate Tax. Real Estate Taxes shall also include reasonable legal fees, costs, and disbursements incurred in connection with proceedings to contest, determine, or reduce Real Estate Taxes;

(iii) repair, maintenance, replacement and supply of air conditioning, electricity, steam, water, heating, ventilating, mechanical, escalator and elevator systems, sanitary and storm drainage systems and all other utilities and mechanical systems which are commonly used by all Buildings tenants;

(iv) landscaping and gardening;

(v) repaving, repairing, maintaining and restriping of parking areas;

(ix) all insurance (including earthquake coverage) carried by Landlord on the Buildings, the Common Area and the Property, or in connection with the use or occupancy thereof, including fire and extended coverage, vandalism and malicious mischief, public liability and property damage, worker’s compensation insurance, rental income insurance and any other insurance commonly carried by prudent owners of comparable buildings;

(x) wages, salaries, payroll taxes and other labor costs and employee benefits for all persons engaged in the operation, management, maintenance and security of the Property and not otherwise on the general payroll of Landlord or an affiliate of Landlord or any property manager other than a person located on site at the Property based on the proportionate amount of time such person devotes to the management of the Property relative to other properties;

(xi) management fees at commercially reasonable rates, provided that, so long as Tenant leases hereunder 100% of the Premises leased by Tenant hereunder as of the Commencement Date, Tenant shall have the right to approve the Property manager, such approval not to be unreasonably withheld or delayed, and Tenant hereby agrees that Legacy Property Management, L.P. is an acceptable manager;

(xii) fees, charges and other costs of all independent contractors engaged by Landlord;

(xiii) license, permit and inspection fees;

(xiv) charges on or surcharges imposed by any governmental agencies on or with respect to transit or automobile usage or parking facilities;

(xv) the cost of supplies, tools, machines and equipment used in operation and maintenance of the Common Area;

(xvi) any Ordinary Capital Improvements; provided that the cost of any such Ordinary Capital Improvements shall be amortized over the useful life of the improvement in question, together with interest on the unamortized balance at the Interest Rate;

(xvii) the cost of contesting the validity or applicability of any governmental enactments including taxes which may affect operating expenses;

(xviii) audit and bookkeeping fees, and legal fees and expenses; and

(xix) any other expenses of any kind whatsoever reasonably incurred in connection with the management, operation, maintenance, repair and replacement of the Buildings and the Common Area.

The parties acknowledge that, concurrently with the Commencement Date, Landlord acquired its interest in the Property from SGRE, an affiliate of Tenant and that, as a result, Landlord and Tenant agreed that Tenant shall pay Operating Expenses under this Lease that shall include all of the foregoing amounts incurred or accruing prior to the Commencement Date and not yet paid.

Notwithstanding anything in the definition of Operating Expenses to the contrary, Operating Expenses shall not include the following, except to the extent specifically permitted by a specific exception to the following:

(A) Costs actually reimbursed to Landlord by insurance proceeds for the repair of damage to the Buildings;

(B) Marketing costs, including without limitation, leasing commissions, space planning costs, and other costs and expenses incurred in connection with lease, sublease and/or assignment negotiations and transactions with Tenant or present or prospective tenants of the Buildings;

(C) Overhead and profit increment paid to Landlord or to subsidiaries or affiliates of Landlord for goods and/or services in or to the Buildings to the extent the same exceeds the costs of such goods and/or services generally available to unaffiliated third parties;

(D) Costs of capital improvements that do not constitute Ordinary Capital Improvements unless Tenant shall request or approve any such capital improvement; and

(E) Interest, principal, points and fees on debts or amortization on any mortgage or mortgages or any other debt instrument encumbering the Buildings or the Property.

5.2 Payment of Operating Expenses. Commencing on the Commencement Date, Tenant shall pay to Landlord as Additional Rent one twelfth (1/12) of Tenant’s Share of Operating Expenses paid or incurred by Landlord for each calendar year or portion thereof during the Term, in advance, on or before the first day of each month in an amount estimated by Landlord as stated in a written notice to Tenant. The parties acknowledge and agree that, so long as the Premises leased by Tenant hereunder shall be the Premises leased by Tenant hereunder as of the Commencement Date, Landlord shall pay items (i), (ii) and (ix) below directly which will then be passed through to Tenant as Operating Expenses and Tenant shall directly pay all other Operating Expenses, and Tenant will be responsible for Landlord’s obligations under Section 8.1. Landlord may by written notice to Tenant revise such estimates from time to time and Tenant shall thereafter make payments on the basis of such revised estimates. With reasonable promptness after the expiration of each calendar year, Landlord will furnish Tenant with a statement (“Landlord’s Expense Statement”) setting forth in reasonable detail the actual Operating Expenses for such year and Tenant’s Share. If Tenant’s Share of the actual Operating Expenses for such year exceeds the estimated Operating Expenses paid by Tenant for such year, Tenant shall pay to Landlord (whether or not this Lease has terminated) the difference between the amount of estimated Operating Expenses paid by Tenant and Tenant’s Share of the actual Operating Expenses within fifteen (15) days after the receipt of Landlord’s Expense Statement. If the total amount paid by Tenant for any year exceeds Tenant’s Share

of the actual Operating Expenses for that year, the excess shall be credited against the next installments of Base Rent due from Tenant to Landlord, or, if after the Termination Date, the excess shall first be credited against any unpaid Base Rent or Additional Rent due and remaining any excess shall be refunded to Tenant concurrently with the furnishing of Landlord’s Expense Statement.

5.3 Proration. If either the Commencement Date or the Termination Date occurs on a date other than the first or last day, respectively, of a calendar year, Tenant’s Share of Operating Expenses for the year in which the Commencement Date or Termination Date occurs shall be prorated based on a 365-day year.

5.4 Normalization. For the purpose of determining Operating Expenses for any partial year, Operating Expenses shall be deemed to accrue uniformly during the entire calendar year. If any part of the Buildings is not fully leased during a calendar year, Operating Expenses shall be adjusted to add amounts and items of Operating Expenses which would normally have been incurred if the Buildings had been fully leased during such calendar year and Tenant’s Share of Operating Expenses (both for the purposes of the initial estimate and year-end reconciliation) shall be based on an assumed full leasing of the Buildings.

5.5 Other Buildings. In the event any facilities, services or utilities used in connection with the Buildings are provided from another building owned or operated by Landlord or vice versa, the costs incurred by Landlord in connection with the operation of the Buildings shall be allocated to Operating Expenses by Landlord on a reasonably equitable basis, subject to the terms of existing covenants and restrictions encumbering the Property.

5.6 Utility Costs. Tenant shall be solely responsible for and shall make all arrangements for all utilities and services exclusively furnished to or used at the Premises, including, without limitation, all water, gas, electricity, sewer service, waste pick-up and any other utilities, materials or services.

5.7 Taxes on Tenant’s Property and Business. At least ten (10) days prior to delinquency, Tenant shall pay all taxes levied or assessed by any local, state or federal authority upon the conduct of Tenant’s business in the Premises or upon Tenant’s Property (as defined in Section 10.4). Upon Landlord’s request, Tenant shall deliver satisfactory evidence of payment of all such taxes. If the assessed value of the Property is increased by the inclusion of a value placed upon Tenant’s Property, Tenant shall pay to Landlord, upon written demand, the taxes so levied against Landlord, or the portion of Landlord’s taxes resulting from said increase in assessment, as determined from time to time by Landlord.

6. GROUND LEASE

6.1 Ground Lease. A copy of the Ground Lease is attached hereto as Exhibit C and the obligations of “Tenant” thereunder (which Tenant hereby agrees it will

In addition, the Landlord shall have all of the rights and remedies granted to the “Landlord” under the Ground Lease, which rights and remedies are incorporated herein by this reference. In accordance with Section 17.5 of this Lease, this Lease is subordinate and subject to the Ground Lease, and Tenant agrees to be bound by and subject to the terms of the Ground Lease.

(b) Tenant shall cooperate with Landlord in the event Landlord determines to exercise its right to subdivide the Property and the Ground Lease into separate “Parcel Leases” (as defined in the Ground Lease), and Tenant hereby consents to any such subdivision and will divide this Lease into separate leases to accommodate any such subdivision, and the parties hereto will enter into any necessary covenants or easements to insure Tenant will have access to the Premises.

(c) So long as this Lease is in effect as to, and Tenant is currently occupying, more than 25% of the Buildings and no Event of Default has occurred, Landlord shall not, without Tenant’s prior consent, exercise any right to terminate the Ground Lease pursuant to the terms thereof. Tenant shall respond to any request for consent to such termination within five (5) business days following receipt thereof, and, if Tenant does not respond within such five (5) business day period, Tenant shall be deemed to have consented. If Landlord terminates the Ground Lease in accordance with the foregoing, this Lease shall terminate.

7. USE OF PREMISES AND CONDUCT OF BUSINESS

7.1 Permitted Use. (a) Tenant (and any permitted successor, assign or subtenant of Tenant, whether by Landlord’s consent or by operation of law) may use and occupy the Premises during the Term solely for the uses specified and permitted in Article 1 and for no other purpose without the prior written consent of Landlord, such consent to be granted or withheld in Landlord’s sole discretion. The foregoing statement shall not constitute a representation or guaranty by Landlord that such business may be conducted in the Premises or is lawful or permissible under any certificates of occupancy issued for the Premises or the Buildings, or is otherwise permitted by law. Tenant’s use of the Premises shall in all respects comply with all Legal Requirements.

(b) If any governmental license or permit shall be required for the proper and lawful conduct of Tenant’s business in the Premises or any part thereof, then Tenant, at its expense, shall duly procure and thereafter maintain such license or permit and shall submit same to Landlord for inspection.

9. ACCEPTANCE

The Premises as furnished by Landlord consist of the improvements as they exist as of the Commencement Date and Landlord shall have no obligation for construction work or improvements on or to the Premises. Prior to entering into this Lease, Tenant has made a thorough and independent examination of the Premises and all matters related to Tenant’s decision to enter into this Lease. Tenant is thoroughly familiar with all aspects of the Premises and is satisfied that they are in an acceptable condition and meet Tenant’s needs. Tenant does not rely on, and Landlord does not make, any express or implied representations or warranties as to any matters including, without limitation, (a) the physical condition of the Premises, the Buildings, the Structural Components, Building Systems, or the Common Area, (b) the existence, quality, adequacy or availability of utilities serving the Premises, (c) the use, habitability, merchantability, fitness or suitability of the Premises for Tenant’s intended use, (d) the likelihood of deriving business from Tenant’s location or the economic feasibility of Tenant’s business, (e) Hazardous Materials in the Premises, the Buildings, or on, in under or around the Property, (f) zoning, entitlements or any laws, ordinances or regulations which may apply to Tenant’s use of the Premises or business operations, or (g) any other matter relating to the Premises. Tenant has satisfied itself as to such suitability and other pertinent matters by Tenant’s own inquiries and tests into all matters relevant in determining whether to enter into this Lease. Tenant accepts the Premises in their existing “as-is” condition. Tenant shall, by entering into and occupying the Premises, be deemed to have accepted the Premises and to have acknowledged that the same are in good order, condition and repair.

10. ALTERATIONS

10.1 Alterations by Tenant. Tenant shall make no improvements, changes or alterations in or to the Premises (“Alterations”) without Landlord’s prior approval. Landlord shall not unreasonably withhold approval to any Alteration that is not a Material Alteration. “Material Alteration” means an Alteration that (i) is not limited to the interior of the Premises or affects the exterior (including the appearance) of the Buildings or entry ways, (ii) is structural or affects the structural integrity of the Buildings or the structural integrity of the Structural Components, (iii) affects the usage or the proper functioning of the Building Systems (other than with respect to the Permitted Lab Work), (iv) requires the consent of any Leasehold Mortgagee or the Landlord under the Ground Lease or (v) requires a change to the Buildings’ certificates of occupancy. Notwithstanding the foregoing, Landlord’s consent shall not be required in the case of Alterations (“Permitted Alterations”) that are not Material Alterations and that do not exceed a total cost of Two Hundred Fifty Thousand Dollars ($250,000) (or Five Hundred Thousand Dollars ($500,000) in the case of Permitted Lab Work per project.

Any determination to be made pursuant to this Section 10.1 as to the cost or price of an Alteration shall be made on a “job-by-job basis” and all work that is part of the same Alteration or integrated or related, whether or not performed in phases or stages, shall be treated as a single Alteration for the purposes of such determination.

10.2 Project Requirements. The following provisions of this Section 10.2 shall apply to all Alterations, whether or not requiring Landlord’s approval (unless otherwise noted):

(a) Tenant, in connection with any Alteration, shall comply with any rules and regulations as may be from time to time established by Landlord and communicated in writing to Tenant. Tenant shall not proceed with any Alteration (other than Permitted Alterations) unless and until Landlord approves Tenant’s plans and specifications therefor. Any review or approval by Landlord of plans and specifications with respect to any Alteration is solely for Landlord’ benefit, and without any representation or warranty to Tenant with respect to the adequacy, correctness or efficiency thereof, its compliance with Legal Requirements or otherwise. Landlord shall, within ten (10) business days following receipt of Tenant’s plans and specifications for the performance of any Alteration that is not a Material Alteration (other than Permitted Alterations), advise Tenant of Landlord’s approval or disapproval of such plans and specifications for such an Alteration or any part thereof. If Landlord shall fail to approve or disapprove Tenant’s plans and specifications for such an Alteration or any part thereof within such ten (10) business day period, Tenant shall have the right to give a reminder notice to Landlord and if Landlord fails to approve or disapprove Tenant’s plans and specifications or any part thereof within such two (2) business days after receipt of such reminder notice, Landlord shall be deemed to have approved such plans and specifications for such an Alteration or the applicable part thereof. If Landlord shall disapprove such plans and specifications for such an Alteration (or any part thereof), Landlord shall set forth in reasonable detail its reasons for such disapproval in writing. Landlord shall advise Tenant within five (5) business days following receipt of Tenant’s revised plans and specifications, or portions thereof, of Landlord’s approval or disapproval of the revised plans and specifications or any portion thereof, and shall set forth in reasonable detail Landlord’s reasons for any such further disapproval in writing and in reasonable detail. If Landlord fails to approve or disapprove the revised plans and specifications for such an Alteration or any portion thereof within such five (5) business day period, Tenant shall have the right to give a reminder notice to Landlord and if Landlord fails to approve or disapprove Tenant’s plans and specifications for such an Alteration or any part thereof within two (2) business days after receipt of such reminder notice, Landlord shall be deemed to have approved the revised plans and specifications or such portions thereof. For the avoidance of doubt, Landlord’s approval of plans and specifications for any Material Alteration may be given or withheld in its sole discretion.

(b) With respect to any Alterations expected to cost more than $100,000, Tenant shall furnish to Landlord one of the following (as selected by Tenant): (i) a cash deposit, (ii) a performance bond and a labor and materials payment bond (issued by a corporate surety licensed to do business in California reasonably satisfactory to Landlord) or (iii) an irrevocable, unconditional, negotiable letter of credit, issued by a bank and in a form satisfactory to Landlord; each to be equal to 125% of the cost of the Alteration, estimated as set forth above. Any such letter of credit shall be for one year and shall be renewed by Tenant each and every year until the Alteration in question is completed and shall be

delivered to Landlord not less than 30 days prior to the expiration of the then current letter of credit, failing which Landlord may present the then current letter of credit for payment. Upon (A) the completion of the Alteration in accordance with the terms of this Article 10 and (B) the submission to Landlord of (x) proof evidencing the payment in full for said Alteration, (y) written unconditional lien waivers of mechanics’ liens and other liens on the Property from all contractors performing said Alteration and (z) all other submissions as may be, from time to time reasonably required by Landlord, the security deposited with Landlord (or the balance of the proceeds thereof, if Landlord has drawn on the same) shall be returned to Tenant. Upon Tenant’s failure properly to perform, complete and fully pay for any Alteration, as determined by Landlord, Landlord may, upon notice to Tenant, draw on the security deposited under this Section 10.2 to the extent Landlord deems necessary in connection with said Alteration, the restoration and/or protection of the Premises or the Property and the payment of any costs, damages or expenses resulting therefrom.

(c) Before commencing the construction of any Alterations, Tenant shall procure or cause to be procured the insurance coverage described below and provide Landlord with certificates of such insurance in form reasonably satisfactory to Landlord. All such insurance shall comply with the following requirements of this Section and of Section 14.2.

(i) During the course of construction, to the extent not covered by property insurance maintained by Tenant pursuant to Section 14.2, comprehensive “all risk” builder’s risk insurance, including vandalism and malicious mischief, excluding earthquake and flood, covering all improvements in place on the Premises, all materials and equipment stored at the site and furnished under contract, and all materials and equipment that are in the process of fabrication at the premises of any third party or that have been placed in transit to the Premises when such fabrication or transit is at the risk of, or when title to or an insurable interest in such materials or equipment has passed to, Tenant or its construction manager, contractors or subcontractors (excluding any contractors’, subcontractors’ and construction managers’ tools and equipment, and property owned by the employees of the construction manager, any contractor or any subcontractor), such insurance to be written on a completed value basis in an amount not less than the full estimated replacement value of Alterations.

(ii) Commercial general liability insurance covering Tenant, Landlord and each construction manager, contractor and subcontractor engaged in any work on the Premises, which insurance may be effected by endorsement, if obtainable, on the policy required to be carried pursuant to Section 14.2, including insurance for completed operations, elevators, owner’s, construction manager’s and contractor’s protective liability, products completed operations for one (1) year after the date of acceptance of the work by Tenant, broad form blanket contractual liability, broad form property damage and full form personal injury (including but not limited to bodily injury), covering the performance of all work at or from the Premises by Tenant, its construction manager, contractors and subcontractors, and in a liability amount not less than the amount at the time

(iii) Workers’ Compensation Insurance approved by the State of California, in the amounts and coverages required under workers’ compensation, disability and similar employee benefit laws applicable to the Premises, and Employer’s Liability Insurance with limits not less than One Million Dollars ($1,000,000) or such higher amounts as may be required by law.

(d) All construction and other work in connection with any Alterations shall be done at Tenant’s sole cost and expense and in a prudent and first class manner. Tenant shall construct the Alterations in accordance with all Legal Requirements, and with plans and specifications that are in accordance with the provisions of this Article 10 and all other provisions of this Lease.

(e) Prior to the commencement of any construction, alteration, addition, improvements, repair or landscaping in excess of Fifty Thousand Dollars ($50,000), Landlord shall have the right to post in a conspicuous location on the Premises and to record in the public records a notice of Landlord’s nonresponsibility. Tenant covenants and agrees to give Landlord at least ten (10) days prior written notice (or concurrent notice in the event of an emergency repair required to protect human health or safety) of the commencement of any such construction, alteration, addition, improvement, repair or landscaping in order that Landlord shall have sufficient time to post such notice.

(f) Tenant shall take all necessary safety precautions during any construction.

(g) Tenant shall prepare and maintain (i) on a current basis during construction, annotated plans and specifications showing clearly all changes, revisions and substitutions during construction, and (ii) upon completion of construction, as-built drawings showing clearly all changes, revisions and substitutions during construction, including, without limitation, field changes and the final location of all mechanical equipment, utility lines, ducts, outlets, structural members, walls, partitions and other significant features. These as-built drawings and annotated plans and specifications shall be kept at the Premises and Tenant shall update them as often as necessary to keep them current. The as-built drawings and annotated plans and specifications shall be made available for copying and inspection by Landlord at all reasonable times, and are subject to Landlord’s approval as provided in subsection (a) above.

(h) Upon completion of the construction of any Alterations in excess of Fifty Thousand Dollars ($50,000) during the Term, Tenant shall file for recordation, or cause to be filed for recordation, a notice of completion and shall deliver to

Landlord evidence satisfactory to Landlord of payment of all costs, expenses, liabilities and Liens arising out of or in any way connected with such construction (except for Liens that are contested in the manner provided herein).

(i) Tenant shall reimburse Landlord within five (5) days following demand for any out-of-pocket expenses incurred by Landlord in the review of any Alterations proposed to be made by Tenant, including fees charged by Landlord’s contractors or consultants to review plans and specifications, and such reimbursement obligation shall constitute Additional Rent hereunder.

(j) Should any Liens be filed against any portion of the Property by reason of the acts or omissions of, or because of a claim against, Tenant or anyone claiming under or through Tenant, Tenant shall cause the same to be canceled or discharged of record by bond or otherwise within twenty (20) business days after notice from Landlord. If Tenant shall fail to cancel or discharge said lien or liens within said twenty (20) business day period, Landlord may cancel or discharge the same and, upon Landlord’s demand, Tenant shall reimburse Landlord for all costs incurred in canceling or discharging such liens, together with interest thereon at the Interest Rate from the date incurred by Landlord to the date of payment by Tenant, such reimbursement to be made within twenty (20) days after receipt by Tenant of a written statement from Landlord as to the amount of such costs. Tenant shall indemnify and hold Landlord harmless from and against all costs (including, without limitation, attorneys’ fees and disbursements and costs of suit), losses, liabilities or causes of action arising out of or relating to any Alteration, including, without limitation, any mechanics’ or other liens asserted in connection with such Alteration.

(k) Tenant shall deliver to Landlord, within sixty (60) days after the completion of an Alteration costing in excess of $50,000, “as-built” drawings thereof. During the Term, Tenant shall keep records of Alterations costing in excess of $50,000 including plans and specifications, copies of contracts, invoices, evidence of payment and all other records customarily maintained in the real estate business relating to Alterations and the cost thereof and shall, within thirty (30) days after demand by Landlord, furnish to Landlord copies of such records.

(l) All Alterations to and fixtures installed by Tenant in the Premises (other than Tenant’s Property) shall be fully paid for by Tenant in cash and not be subject to conditional bills of sale, chattel mortgages, or other title retention agreements.

10.3 Restoration Obligations. (a) Landlord shall have the right to require Tenant to restore the Premises or any portion or component thereof, including any Building System or any portion or component thereof, affected by any Alteration to its condition prior to the commencement of such Alteration, which restoration Tenant shall have the obligation to complete by no later than the Expiration Date provided that: (i) Landlord notifies Tenant that Landlord shall require restoration of an Alteration within thirty (30) days after receipt by Landlord of plans and specifications for such Alteration and in no event later than Landlord’s approval pursuant to Section 10.1; and (ii) solely with respect to any Permitted Alteration,

Landlord reasonably determines that the failure to effect the restoration would lessen the value, utility or efficiency of the Premises as a multi-tenanted office and research and development building at the end of the Term of this Lease. For the avoidance of doubt clause (ii) and Section 10.3(b) shall not apply to any Alteration that is not a Permitted Alteration. All work performed in connection with Tenant’s restoration obligations shall constitute Alterations and shall be subject to the provisions of this Article 10 and all other provisions of this Lease which govern the performance of Alterations.

(b) Within fifteen (15) days after receipt by Tenant of Landlord’s notification that Landlord shall require Tenant to restore any Permitted Alteration, Tenant shall notify Landlord as to whether Tenant accepts or rejects Landlord’s determination. Any failure by Tenant to so notify Landlord shall be deemed to be Tenant’s irreversible acceptance of the obligation to restore the applicable Alteration. Landlord and Tenant shall endeavor to resolve any dispute as to whether Tenant has an obligation to restore any Alteration within thirty (30) days after Tenant shall notify Landlord that Tenant has rejected Landlord’s determination. If Landlord and Tenant shall be unable to resolve any such dispute within such 30-day period, then at any time thereafter any party shall have the right to submit the matter to arbitration in accordance with Section 18.4; provided, however, that in no event shall Tenant be prohibited from performing the Alteration in question pending the resolution of such dispute if Tenant elects to proceed with the applicable Alteration in accordance with the provisions of this Article 10. The term “restore” or “restoration” as used in this Article 10 shall mean that Tenant shall repair, alter, restore, replace and rebuild the Premises, or portion or component thereof, including any Building System or portion or component thereof, affected by the applicable Alteration at least to the extent of the value and as nearly as reasonably practicable to the condition, quality and class existing immediately prior to the performance of the applicable Alteration (using materials, equipment and construction techniques which are common at the time of the performance of the restoration); provided, however, that if in Landlord’s reasonable judgment because of any circumstances relating to construction methods or materials which did not exist at the time of performance of the applicable Alteration or which no longer exist or are no longer legal or insurable or because of other Alterations made by Tenant or other changed circumstances restoration would not be reasonably practical with respect to the required restoration of the applicable Alteration, then Landlord shall have the right to require that the restoration be performed in such a manner specified by Landlord that does not conform to the conditions, quality or class of improvement existing immediately before the applicable Alteration. Any dispute regarding the performance of any required restoration of any Alteration which the parties shall be unable to resolve within fifteen (15) business days after one party shall have notified the other party that a bona fide dispute exists shall be resolved by arbitration in accordance with Section 18.4.

(c) (i) Tenant shall be required to deposit security with Landlord to secure Tenant’s obligation to restore any Alteration in an amount sufficient to secure the restoration of the Alteration in a manner consistent with Section 10.2(b).

(ii) To the extent that Landlord shall be holding any such security, Landlord shall have the right from time-to-time to require Tenant to deposit additional security as it pertains to any and all Alterations made by Tenant which Tenant shall be obligated to restore under this Article 10, if Landlord shall reasonably establish that the security then held by Landlord with respect to any and all such Alterations will be inadequate for their intended purposes. Any dispute regarding the sufficiency of any security deposited with Landlord which the parties shall be unable to resolve within fifteen (15) days after one party shall have notified the other party that such a bona fide dispute exists and shall be resolved by arbitration in accordance with Section 18.4.

(iii) To the extent that Landlord shall be holding any such security, Landlord shall be permitted to use such security to complete Tenant’s obligation to restore the Alteration with respect to which such security has been deposited by Tenant if Tenant shall default in Tenant’s obligation to restore the applicable Alteration. If at any time Landlord shall notify Tenant that Landlord or its consultants shall have concluded that there is a substantial likelihood that any Alteration that Tenant is obligated to restore or any Turnover Alteration will not be completed by the date by which it shall be required to be completed hereunder, then for the period of thirty (30) days following such notification by Landlord to Tenant, Landlord and Tenant and their respective architects and/or engineers shall endeavor to resolve the matter. If the parties shall be unable to resolve the matter, then at any time after the expiration of such thirty (30) day period, either party may submit the matter to arbitration under Section 18.4 hereof, with the sole question to be determined by such arbitration being whether or not there is a substantial likelihood that any such Alteration will not be completed by the date by which it shall be required to be completed hereunder. If the arbitration is determined in favor of Landlord, then Landlord shall have the right (but shall not be obligated) to use any security then on deposit with Landlord to complete the same. In the event that Landlord shall complete such Alteration for a cost that is less than the then available balance of any security deposited to secure Tenant’s obligation to perform the Alteration in question, then any excess unused portion of such security being held by Landlord after the restoration of the applicable Alteration with respect to which it was deposited with Landlord shall belong to and promptly be refunded by Landlord to Tenant.

(d) Notwithstanding anything to the contrary contained in this Article 10 or elsewhere in this Lease, Tenant shall be obligated to surrender the Premises and the Buildings on the Expiration Date, in the condition and quality that the Premises and the Buildings (including, without limitation, the Building Systems) would have been in at the time of such surrender had Tenant complied with the terms of this Lease (any such Alteration required to be performed by Tenant to satisfy the foregoing requirement being herein referred to as a “Turnover Alteration”). During the period of one hundred and twenty days (120) days prior to the Expiration Date, Landlord shall notify Tenant, and Landlord and Tenant shall endeavor to agree upon any Turnover Alteration remaining to be performed by Tenant. If the parties shall be unable to resolve any dispute regarding whether Tenant has an obligation to perform any Turnover Alteration or regarding the manner in which the same shall be required to be performed within such one hundred and twenty (120) day period, then

either party may submit the matter to arbitration in accordance with Section 18.4. All Turnover Alterations shall be performed in accordance with the provisions of this Article 10 and other portions of this Lease applicable to Alterations.

(e) Notwithstanding anything to the contrary contained in this Article 10 or elsewhere in this Lease, Tenant shall not perform any Alteration which Tenant shall be obligated to restore under this Article 10 unless the restoration of such Alteration can be completed as and when required under Article 10.

(f) Without limiting the generality of any other provision of this Lease, in the event that Tenant shall fail to restore any Alteration that it is obligated hereunder to restore or shall fail to perform any Turnover Alteration, and the failure to perform same shall interfere with the use and occupancy of the Premises or any portion thereof, then Tenant shall be liable to Landlord for failure to make such Turnover Alterations.

10.4 Ownership of Improvements. Except as provided in Section 10.5, all Alterations, and any other appurtenances, fixtures, improvements, equipment, additions and property permanently attached to or installed in the Premises at the commencement of or during the Term, shall at the end of the Term become Landlord’s property without compensation to Tenant, or be removed in accordance with this Section. Landlord shall notify Tenant in writing at the time of Landlord’s approval of the Alterations, as applicable, whether or not the proposed Alterations will be required to be removed by Tenant at the end of the Term. Tenant shall have no obligation to remove any Alterations that Landlord has not designated in writing for removal. Tenant shall repair or pay the cost of repairing any damage to the Premises or to the Buildings caused by the removal of Alterations. If Tenant fails to perform its repair obligations, without limiting any other right or remedy, Landlord may on five (5) business days prior written notice to Tenant perform such obligations at Tenant’s expense and Tenant shall promptly reimburse Landlord upon demand for all out-of-pocket costs and expenses incurred by Landlord in connection with such repair. In addition, any such reimbursement shall include a fifteen percent (15%) administrative fee to cover Landlord’s overhead in undertaking such repair. The reimbursement and administrative fee shall be Additional Rent. Tenant’s obligations under this Section shall survive the termination of this Lean.

10.5 Tenant’s Personal Property. All furniture, trade fixtures, furnishings, equipment and articles of movable personal property installed in the Premises by or for the account of Tenant (except for ceiling and related fixtures, HVAC equipment and floor coverings), and which can be removed without structural or other material damage to the Buildings (collectively, “Tenant’s Property”) shall be and remain the property of Tenant and may be removed by it at any time during the Term and Tenant may xxxxx x Xxxx on such personal property. Tenant shall remove from the Premises all Tenant’s Property on or before the Termination Date, except such items as the parties have agreed pursuant to the provisions of this Lease or by separate agreement are to remain and to become the property of Landlord.

Tenant shall repair or pay the cost of repairing any damage to the Premises or to the Buildings resulting from such removal, and the provisions of Section 10.4 above shall apply in the event Tenant fails to do so. Any items of Tenant’s Property which remain in the Premises after the Termination Date may, on five (5) business days prior written notice to Tenant, at the option of Landlord, be deemed abandoned and in such case may either be retained by Landlord as its property or be disposed of, without accountability, at Tenant’s expense in such manner as Landlord may see fit.

11. LIENS

Tenant shall promptly pay, in cash, the cost of all Alterations, repairs, restorations or replacements made by or on behalf of Tenant. Tenant shall keep the Premises free from any Liens arising out of any work performed, material furnished or obligations incurred by or for Tenant. Tenant hereby indemnifies Landlord against liability for any and all Liens arising out of work performed, material furnish or obligations incurred by or for Tenant. If Tenant shall not, within ten (10) days following notice of the imposition of any such Lien, cause the Lien to be released of record by payment or posting of a proper bond, Landlord shall have, in addition to all other remedies provided in this Lease and by law, the right but not the obligation to cause any such Lien to be released by such means as it shall deem proper, including payment of the claim giving rise to such Lien. All such sums paid by Landlord and all expenses incurred by it in connection therewith (including, without limitation, reasonable counsel fees) shall be payable to Landlord by Tenant within five (5) days of Landlord’s demand with interest from the date incurred at the Interest Rate. Landlord shall have the right at all times to post and keep posted on the Premises any notices permitted or required by law or that Landlord shall deem proper for the protection of Landlord, the Premises, and the Buildings from Liens.

Landlord shall at its own cost and expense, take such action as may be necessary (by bonding or other appropriate action) to duly discharge and satisfy in full promptly any Lessor Lien, provided, however, Landlord need not discharge or satisfy any Lessor Lien being contested by Landlord in good faith and by appropriate proceedings so long as such proceedings do not involve any material danger of sale, forfeiture or loss of any part of Tenant’s leasehold interest in the Property. In addition, Landlord shall use commercially reasonable efforts to cause persons claiming by, through or under Landlord (excluding Tenant) to promptly discharge and satisfy in full any Lien against Tenant’s leasehold interest in the Property. “Lessor Liens” means Liens against the Property or the Ground Lease that result from (i) claims against the Landlord or (ii) Real Estate Taxes payable by Landlord which are not required to be paid by Tenant. For the avoidance of doubt, the foregoing shall not apply to any Leasehold Mortgage or Lien related thereto, any Prior Lease, any Lien in effect as of the Commencement Date or any other Lien permitted by the terms of this Lease.

Alterations and Landlord shall comply with all Legal Requirements applicable with respect to Landlord’s obligations under this Lease. Without limiting the foregoing, Tenant shall be solely responsible for compliance with and shall make or cause to be made all such improvements and alterations to the Premises (including, without limitation, removing barriers and providing alternative services) as shall be required to comply with all applicable building codes, laws and ordinances relating to public accommodations, including the Americans with Disabilities Act of 1990, 42 U.S.C. §§ 12111 et seq.

12.2 Insurance Requirements. (a) Tenant shall not do anything, or permit anything to be done, in or about the Premises that would: (i) invalidate or be in conflict with the provisions of or cause any increase in the applicable rates for any fire or other insurance policies covering the Buildings or any property located therein (unless Tenant pays for such increased costs), or (ii) result in a refusal by fire insurance companies of good standing to insure the Buildings or any such property in amounts reasonably satisfactory to Landlord (which amounts shall be comparable to the amounts required by comparable landlords of comparable buildings, (iii) subject Landlord to any liability or responsibility for injury to any person or property by reason of any business operation being conducted in the Premises or by Tenant or any one claiming under Tenant elsewhere on the Property, or (iv) result in the cancellation of or assertion of any defense by the insurer to any claim under any policy of insurance maintained by or for the benefit of Landlord. Tenant, at Tenant’s expense, shall comply with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body that shall hereafter perform the function of such Association.

(b) If, by reason of any act or omission on the part of Tenant which is inconsistent with the use permitted hereunder, whether or not Landlord has consented to the same, the rate of “all risk” or other type of insurance maintained by Landlord on the Property or the Buildings or other property of Landlord shall be higher than it otherwise would be, but for such act or omission, Tenant shall reimburse Landlord for that part of the premiums for such insurance paid by Landlord because of such act or omission on the part of Tenant, which sum shall be Additional Rent and payable within five (5) days of demand. If,

due to the occupancy or abandonment of, or Tenant’s failure to occupy, the Premises as herein provided, any such insurance shall be canceled by the insurance carrier, then, in any of such events, Tenant hereby indemnifies Landlord against liability which would have been covered by such insurance. Landlord shall give Tenant notice of any such cancellation promptly after Landlord shall have received written notice thereof. Tenant shall also pay any increase in premiums on any rent insurance carried by Landlord for its protection against rent loss through fire or casualty if such increase shall result from any of the foregoing events.

Tenant has made such investigations and inquiries as it deems appropriate to ascertain the effects, if any, of such substances and contaminants on its operations and persons using the Buildings and the Common Area. Landlord makes no representation or warranty with regard to the environmental condition of the Buildings, the Common Area or the Property. Tenant hereby releases Landlord and Landlord’s officers, directors, trustees, agents and employees from any and all claims, demands, debts, liabilities, and causes of action of whatever kind or nature, whether known or unknown or suspected or unsuspected which Tenant or any of Tenant’s Agents may have, claim to have, or which may hereafter accrue against the released parties or any of them, arising out of or relating to or in any way connected with Hazardous Materials presently in, on or under, or now or hereafter emanating from or migrating onto the Buildings or the Property (except to the extent such emanation or migration is caused by Landlord or Landlord’s Agents). In connection with such release, Tenant hereby waives any and all rights conferred upon it by the provisions of Section 1542 of the California Civil Code, which reads as follows:

A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor.

13.4 Indemnity. Tenant shall indemnify, defend (by counsel reasonably acceptable to Landlord), protect and hold Landlord and Landlord’s trustees, directors, officers, agents, shareholders, direct or indirect beneficial owners and employees, any Leasehold Mortgagees, any Prior Lessors, and their respective successors and assigns (collectively, “Landlord’s Agents”), free and harmless from and against any and all claims, liabilities, penalties, forfeitures, losses or expenses (including reasonable attorneys’ and consultants’ fees and oversight and response costs) to the extent arising from (a) Environmental Activity by Tenant or Tenant’s Agents; or (b) failure of Tenant or Tenant’s Agents to comply with any Environmental Law with respect to Tenant’s Environmental Activity; or (c) Tenant’s failure to remove Tenant’s Hazardous Materials as required in Section 13.3.

13.5 No Lien. Tenant shall not suffer any Lien to be recorded against the Buildings or the Property as a consequence of any Tenant’s Hazardous Materials, including any so called state, federal or local “super fund” Lien related to the remediation of any Tenant’s Hazardous Materials in or about the Buildings or the Property.

13.6 Investigation. In the event Hazardous Materials are discovered in or about the Buildings or the Property, and Landlord reasonably believes that such Hazardous Materials are Tenant’s Hazardous Materials, then Landlord shall have the right to appoint a consultant to conduct an investigation to determine the nature and extent of such Hazardous Materials, whether such Hazardous Materials are Tenant’s Hazardous Materials, and the corrective measures, if any, required to remove such Hazardous Materials. If such Hazardous Materials are determined to be Tenant’s Hazardous Materials, Tenant, at its expense, shall comply with all investigation, remediation or other actions required by any applicable governmental authority and reasonably approved by Landlord and shall promptly reimburse Landlord for all costs incurred by Landlord in connection with such investigation, along with a fifteen percent (15%) administrative fee to cover Landlord’s costs and overhead in undertaking or supervising such work. The reimbursement and administrative fee shall be Additional Rent.

13.7 Notices. Tenant shall notify Landlord of any inquiry, test, claim, investigation or enforcement proceeding by or against Tenant or the Premises or the Property known to Tenant within five (5) business days of obtaining knowledge thereof concerning any Hazardous Materials.

Tenant acknowledges that Landlord, as the owner of the Property, shall have the sole right at its election and at

Tenant’s expense, to negotiate, defend, approve and appeal any action taken or order issued with regard to Tenant’s Hazardous Materials by any applicable governmental authority.

13.8 Surrender. Tenant shall surrender the Premises to Landlord, upon the expiration or earlier termination of the Lease, free of Tenant’s Hazardous Materials except for Permitted Substances and other Hazardous Materials the presence of which would not and could not reasonably be expected to result in a violation of any Legal Requirements or pose a threat to human health or safety. If Tenant fails to so surrender the Premises, Tenant shall indemnify and hold Landlord harmless from all losses, costs, claims, damages and liabilities resulting from Tenant’s failure to surrender the Premises as required by this Section 13.8, including, without limitation, (a) any claims or damages arising in connection with the condition of the Premises, and (b) damages occasioned by Landlord’s inability to relet the Premises or a reduction in the fair market and/or rental value of the Buildings or any portion thereof, by reason of the existence of any Tenant’s Hazardous Materials.

13.9 Survival. The provisions of this Article 13 shall survive the expiration or earlier termination of this Lease.

14. INDEMNITY; INSURANCE

Tenant shall indemnify, protect, defend and save and hold Landlord, Landlord’s Agents (the “Indemnified Parties”) harmless from and against any and all losses, costs, liabilities, claims, judgments, liens, damages (including consequential damages) and expenses, including, without limitation, reasonable attorneys’ fees and costs, and reasonable investigation costs, incurred in connection with or arising from: (a) any default by Tenant in the observance or performance of any of the terms, covenants or conditions of this Lease on Tenant’s part to be observed or performed, including Tenants obligations under Article 6 with respect to the Ground Lease, (b) the use or occupancy or manner of use or occupancy of the Premises, the Buildings and the Property by Tenant and Tenant’s Agents or any person claiming under Tenant, (c) the condition of the Premises, and any occurrence on the Premises, the Buildings or the Property from any cause whatsoever, except to the extent caused by the gross negligence or willful misconduct of the Indemnified Parties, and (d) any acts or omissions or negligence of Tenant or of Tenant’s Agents, in, on or about the Premises, the Buildings or the Common Area. In case any action or proceeding be brought, made or initiated against the Indemnified Parties relating to any matter covered by Tenant’s indemnification obligations under this Section or under Section 13.4, Tenant, upon notice from the Landlord, shall at its sole cost and expense, resist or defend such claim, action or proceeding by counsel approved by the Indemnified Parties. Notwithstanding the foregoing, each of the Indemnified Parties may retain its own counsel to defend or assist in defending any claim, action or proceeding, and Tenant shall pay the reasonable fees and disbursements of such counsel. Tenant’s obligations under this Section shall survive the expiration or earlier termination of this Lease. Each of the Indemnified Parties is an intended third-party beneficiary of this Section 14.1 and shall be entitled to enforce the provisions hereof.

14.2 Insurance. Tenant shall procure at its sole cost and expense and keep in effect during the Term:

(a) commercial general liability insurance covering Tenant’s operations in the Premises and the use and occupancy of the Premises. Such insurance shall include broad form contractual liability insurance coverage insuring Tenant’s obligations under this Lease. Such coverage shall be written on an “occurrence” form and shall have a minimum combined single limit of liability of not less than Ten Million Dollars ($10,000,000). Tenant’s policy shall be written to apply to all bodily injury, property damage, personal injury and other covered loss (however occasioned) occurring during the policy term, with at least the following endorsements to the extent such endorsements are generally available: (i) deleting any employee exclusion on personal injury coverage, (ii) including employees as additional insureds, (iii) providing broad form property damage coverage and products completed operations coverage (where applicable), (iv) deleting any liquor liability exclusions, and (v) providing for coverage of owned and non-owned automobile liability, if applicable. Such insurance shall name Landlord and any Leasehold Mortgagee and Prior Lessor designated by Landlord as an additional insured, shall specifically include the liability assumed hereunder by Tenant, shall provide that it is primary insurance, shall provide for severability of interests, shall further provide that an act or omission of one of the named insureds which would void or otherwise reduce coverage shall not reduce or void the coverage as to any insured, shall afford coverage for claims based on acts, omissions, injury or damage which occurred or arose (or the onset of which occurred or arose) in whole or in part during the policy period, and shall provide that Landlord will receive thirty (30) days’ written notice from the insurer prior to any cancellation;

(b) commercial property insurance, including sprinkler leakages, vandalism and malicious mischief and plate glass damage covering all the items specified as Tenant’s Property and all other property of every description including stock-in-trade, furniture, fittings, installations, alterations, additions, partitions and fixtures or anything in the nature of a leasehold improvement made or installed by or on behalf of the Tenant in an amount of not less than one hundred percent (100%) of the full replacement cost thereof as shall from time to time be determined by Tenant in form satisfactory to Landlord;

(c) Worker’s Compensation Insurance in the amounts and coverages required under worker’s compensation, disability and similar employee benefit laws applicable to Tenant and/or the Premises from time to time, and Employer’s Liability Insurance, with limits of not less than one million dollars ($1,000,000) such higher amounts as may be required by law; and

(d) any other form or forms of insurance as Landlord may reasonably require from time to time (other than insurance that Landlord is required to maintain) in amounts and for insurable risks (on commercially reasonable terms) against which a prudent tenant would protect itself to the extent landlords of comparable buildings in the vicinity of the Buildings require their tenants to carry such other form(s) of insurance.

14.3 Policies. All policies of insurance provided for herein shall be issued by insurance companies with general policyholders’ rating of not less than A, as rated in the most current available “Best’s Insurance Reports,” and not prohibited from doing business in the State of California, and shall, with the exception of Workers Compensation Insurance, include as additional insureds Landlord, and such Leasehold Mortgagees and Prior Lessors as Landlord specifies from time to time. Such policies shall be for the mutual and joint benefit and protection of Landlord, Tenant and others specified by Landlord. Certificates of insurance shall be delivered to Landlord prior to the delivery of possession of the Premises to Tenant and thereafter within thirty (30) days prior to the expiration of the term of each such policy. All commercial general liability and property damage policies shall contain a provision that Landlord and any other additional insured, although named as additional insureds, shall nevertheless be entitled to recover under said policies for a covered loss occasioned by it, its servants, agents and employees, by reason of Tenant’s negligence. As often as any policy shall expire or terminate, renewal or additional policies shall be procured and maintained by Tenant in like manner and to like extent. All such policies of insurance shall provide that the company writing said policy will give to Landlord thirty (30) days notice in writing in advance of any cancellation. All commercial general liability, property damage and other casualty policies shall be written on an occurrence basis. Landlord’s coverage shall not be contributory. No policy shall have a deductible in excess of $200,000 for any one occurrence.

14.4 Landlord’s Rights. Should Tenant fail to take out and keep in force each insurance policy required under this Article 14, or should such insurance not be approved by Landlord and should the Tenant not rectify the situation within two (2) business days after written notice from Landlord to Tenant, Landlord shall have the right, without assuming any obligation in connection therewith, to purchase such insurance at the sole cost of Tenant, and all costs incurred by Landlord shall be payable within five (5) days of demand to Landlord by Tenant as Additional Rent and without prejudice to any other rights and remedies of Landlord under this Lease. In addition, at any time, Landlord may elect to insure all or any part of the Premises under its own policy or policies of insurance, and the cost of any such policies shall be an Operating Expense hereunder.

14.5 Waiver of Subrogation. Notwithstanding anything to the contrary in this Lease, the parties hereto release each other and their respective agents, employees, successor, assignees and subtenants from all liability for injury to any person or damage to any property that is caused by or results from a risk (i) which is actually insured against, to the extent of receipt of payment under such policy (unless the failure to receive payment under any such policy results from a failure of the insured party to comply with or observe the terms and conditions of the insurance policy covering such liability, in which event, such release shall not be so limited), (ii) which is required to be insured against under this Lease, or (iii) which would normally be covered by the standard form of “all risk-extended coverage” casualty insurance, without regard to the negligence or willful misconduct of the entity so released. Landlord and Tenant shall each obtain from their respective insurers under all policies of fire, theft, and other property insurance maintained by either of them at

any time during the Term insuring or covering the Project or any portion thereof of its contents therein, a waiver of all rights of subrogation which the insurer of one party might otherwise, if at all, have against the other party, and Landlord and Tenant shall each indemnify the other against any loss or expense, including reasonable attorneys’ fees, resulting from the failure to obtain such waiver.

14.6 No Liability. No approval by Landlord of any Tenant insurer, or the terms or conditions of any policy, or any coverage or amount of insurance, or any deductible amount shall be construed as a representation by Landlord of the solvency of the insurer or the sufficiency of any policy or any coverage or amount of insurance or deductible and Tenant assumes full risk and responsibility for any inadequacy of insurance coverage or any failure of insurers.

15. ASSIGNMENT AND SUBLETTING

15.1 Consent Required. Except as otherwise explicitly provided herein, Tenant shall not directly or indirectly, voluntarily or by operation of law, sell, assign, encumber, pledge or otherwise transfer or hypothecate all or any part of its interest in or rights with respect to the Premises or its leasehold estate (collectively, “Assignment”), or permit all or any portion of the Premises to be occupied by anyone other than itself or sublet all or any portion of the Premises (collectively, “Sublease”) without Landlord’s prior written consent, which Landlord may withhold in its sole and absolute discretion.

15.2 Notice. If Tenant desires to enter into a Sublease of the Premises or Assignment of this Lease, it shall give written notice (the “Transfer Notice”) to Landlord of its intention to do so, which notice shall contain (a) the name and address of the proposed assignee, subtenant or occupant (the “Transferee”), (b) the nature of the proposed Transferee’s business to be carried on in the Premises, (c) the terms and provisions of the proposed Assignment or Sublease, and (d) such financial information as Landlord may reasonably request concerning the proposed Transferee.

15.3 Terms of Approval. Landlord shall respond to Tenant’s request for approval within fifteen (l5) business days after receipt of the Transfer Notice, and if Landlord fails to respond within such fifteen (15) day period, Landlord shall be deemed to have disapproved such proposed Assignment or Sublease. If Landlord approves the proposed Assignment or Sublease, or if an Assignment or Sublease is permitted by operation of law, Tenant may, not later than thirty (30) days thereafter, enter into the Assignment or Sublease with the proposed Transferee upon the terms and conditions set forth in the Transfer Notice, and one hundred percent (100%) of the Excess Rent received by Tenant shall be paid to Landlord as and when received by Tenant. “Excess Rent” means the gross revenue received from the Transferee during the Sublease term or with respect to the Assignment, less (a) the gross revenue paid to Landlord by Tenant during the period of the Sublease term or during the Assignment; (b) any reasonably documented tenant improvement allowance or other economic concession (planning allowance, moving expenses, etc.), paid by Tenant to the Transferee or to a third party in connection with the transfer, (d) customary and reasonable

external brokers’ commissions to the extent paid and documented; (e) reasonable attorneys’ fees; and (f) reasonable costs of advertising the space for Sublease or Assignment (collectively, “Transfer Costs”). Tenant shall not have to pay to Landlord any Excess Rent until Tenant has recovered its Transfer Costs.

15.4 Certain Conditions Applicable to All Sublettings and Assignments. Any assignment or subletting will also be subject to the following conditions:

(a) At least thirty (30) days prior to the date on which such subletting or assignment shall become effective, Tenant shall furnish to Landlord all of the documents and information required under this Section 15.4 together with the Transfer Notice.

(b) At both the time of Tenant’s furnishing to Landlord the information and documents required under this Section 15.4 and the time at which the subletting or assignment becomes effective, an Event of Default shall not have occurred.

(c) If required, the consent of any Leasehold Mortgagee under such Leasehold Mortgage shall have been obtained and Tenant shall have paid to Landlord, or at Landlord’s election reimbursed Landlord for, any charges or payments which are the responsibility of Landlord under the Leasehold Mortgage in connection with such subletting or assignment.

(d) Tenant shall furnish to Landlord a copy of the final executed copy of the Sublease or Assignment documents used in connection with the Sublease or Assignment at, and of each instrument delivered in connection therewith within five (5) business days after the execution and delivery thereof.

(e) Such Sublease or Assignment shall be for the actual use and physical occupancy of the Premises, in the case of an Assignment, and the portion of the Premises sublet, in the case of a Sublease, by the assignee or subtenant, as applicable.

(f) No assignee or subtenant shall be a person having, directly or indirectly, sovereign or diplomatic immunity or having immunity from (or otherwise not being subject to) the service of process in and the jurisdiction of the courts of California.

(g) Following the proposed Assignment or Sublease, the assignee or subtenant shall use the Premises only for the specific use permitted under Article 7.

(h) The instrument of Sublease or Assignment shall not purport to grant to the subtenant or assignee thereunder any rights greater than or inconsistent with those granted to Tenant under this Lease, including for this purpose any term in the instrument of assignment or sublease for which there is no corresponding term in this Lease resulting in such greater rights or inconsistency.

(i) In the case of any subletting, the term thereof (including any extension options) shall in all respects be consistent with Article 10 and shall not prevent Tenant from delivering vacant possession, free and clear of any subtenancies, of the Premises or the applicable portion thereof, on the Expiration Date.

15.5 Short Term Subletting. Notwithstanding the provisions of Section 15.1 to the contrary, with Landlord’s prior consent which consent shall not be unreasonably withheld or delayed, Tenant can enter into a Sublease of one floor or less of Rentable Area with one (i) or more sublessees (but all of such subleases shall cover, individually or collectively, not more than 80,000 square feet of Rentable Area in the aggregate at any given time) for a term of less than the lesser of (i) twenty-four (24) months or (ii) the remainder of the Term, provided that fifty percent (50%) of the Excess Rent received by Tenant shall be paid to Landlord as and when received by Tenant and Tenant shall be entitled to keep the remaining fifty percent (50%). If Landlord does not respond to Tenant’s written request to a proposed short term Sublease meeting the requirements set forth above, within ten (10) business days following receipt thereof, Landlord shall be deemed to have approved such short term Sublease.

15.6 No Release. No Sublease or Assignment by Tenant nor any consent by Landlord thereto shall relieve Tenant of any obligation to be performed by Tenant under this Lease. Any Sublease or Assignment that is not in compliance with this Article shall be null and void and, at the option of Landlord, shall constitute an Event of Default by Tenant under this Lease, and Landlord shall be entitled to pursue any right or remedy available to Landlord under the terms of this Lease or under the laws of the State of California. The acceptance of any Rent or other payments by Landlord from a proposed Transferee shall not constitute consent to such Sublease or Assignment by Landlord or a recognition of any Transferee, or a waiver by Landlord of any failure of Tenant or other Transferor to comply with this Article.

15.7 Change in Control; Successor Entity. (a) For the purposes of this Lease, any transfer of control of Tenant, by operation of law or otherwise, whether pursuant to one transaction or a series of transactions and whether at one time or over a period of time (a “Change in Control”), shall be deemed an Assignment and shall be subject to all of the provisions of this Article 15, including, without limitation, the requirement that Tenant obtain Landlord’s prior written consent thereto, except as provided in Section 15.5. For purposes of this Section 15.7, a transfer of control of Tenant shall be deemed to have occurred if there shall be any of the following: (i) a transfer of the ultimate beneficial ownership of fifty percent (50%) or more of the equity interests in Tenant or of any class of equity interests in Tenant, including, without limitation, by the issuance of additional shares or other equity interests in Tenant, (ii) a transfer of the right to receive fifty percent (50%) or more of any category of distributions made by Tenant, or (iii) a transfer of the right to direct the management of Tenant, by contract or otherwise. Notwithstanding the foregoing, (i) if Tenant is a Public Company, Landlord’s consent shall not be required with respect to transfers of the capital stock of such Tenant on a national securities exchange, unless such

transfers constitute a Change of Control and (ii) Landlord’s consent shall not be required with respect to transfers to Successor Entities permitted in paragraph (b) below.

(b) Tenant shall have the right, subject to Tenant’s complying with Section 15.4, upon not less than fifteen (15) days’ prior written notice to Landlord, to assign its entire interest in this Lease and the leasehold estate hereby created to a Successor Entity (as such term is hereinafter defined) of Tenant, provided that the Successor Entity shall not be entitled, either directly or indirectly, to diplomatic or sovereign immunity and shall be subject to the service of process in and the jurisdiction of the courts of the State of California. A “Successor Entity”, as used in this Section shall mean a corporation or other business entity (i) into which or with which Tenant, its corporate or other successors or permitted assigns, is merged or consolidated, in accordance with applicable statutory provisions for the merger or consolidation of a corporation or other business entity or (ii) which acquires all or substantially all of the Tenant’s assets, provided that by operation of law or by effective provisions contained in the instruments of merger or consolidation or acquisition, the liabilities of the entities participating in such merger or consolidation or acquisition are assumed by the corporation or other business entity surviving such merger or consolidation or acquisition, above, provided that, (x) immediately after giving effect to any such merger or consolidation or acquisition, as the case may be, the corporation or other business entity surviving such merger or acquisition shall have a Net Worth of not less than the Minimum Net Worth and (y) proof of such assets, capitalization and Net Worth, as evidenced by a statement from an Acceptable Accounting Firm, shall have been delivered to Landlord at least ten (10) days prior to the effective date of any such merger or consolidation, or acquisition and assumption, as the case may be.

15.8 Assumption of Obligations. Any Transferee shall, from and after the effective date of the Assignment, assume all obligations of Tenant under this Lease with respect to the transferred space and shall be and remain liable jointly and severally with Tenant for the payment of Base Rent and Additional Rent, and for the performance of all of the terms, covenants, conditions and agreements herein contained on Tenant’s part to be performed for the Term as it relates to the transferred space. No Assignment shall be binding on Landlord unless Tenant complies with the provisions of this Article 15 and delivers to Landlord a counterpart of the Assignment and an instrument that contains a covenant of assumption reasonably satisfactory in substance and form to Landlord, and consistent with the requirements of this Section.

15.9 Insolvency or Bankruptcy. In no event shall this Lease be assigned or assignable by operation of law or by voluntary or involuntary bankruptcy proceedings or otherwise and in no event shall this Lease or any rights or privileges hereunder be an asset of Tenant under any bankruptcy, insolvency, reorganization or other debtor relief proceedings.

15.10 Recovery of Premises. If Landlord shall recover or come into possession of the Premises before the date herein fixed for the termination of this Lease, Landlord shall have the right, at its option, to take over any and all Subleases of the Premises

or any part thereof made by Tenant and to succeed to all the rights of said Subleases or such of them as it may elect to take over. Tenant hereby expressly assigns and transfers to Landlord such of the Subleases as Landlord may elect to take over at the time of such recovery of possession, such assignment and transfer not to be effective until the termination of this Lease or re-entry by Landlord hereunder or if Landlord shall otherwise succeed to Tenant’s interest in the Premises, at which time Tenant shall upon request of Landlord, execute acknowledge and deliver to Landlord such further assignments and transfers as may be necessary to vest in Landlord the then existing Subleases. Each subletting hereunder is subject to the condition and by its acceptance of and entry into a Sublease, each subtenant thereunder shall be deemed conclusively to have thereby agreed from and after the termination of this Lease or re-entry by Landlord hereunder or if Landlord shall otherwise succeed to Tenant’s interest in the Premises, that such subtenant shall waive any right to surrender possession or terminate the Sublease and, at Landlord’s election, such subtenant shall be bound to Landlord for the balance of the term of such Sublease and shall attorn to and recognize Landlord as its landlord under all of the then executory terms of such Sublease, except that Landlord shall not (i) be liable for any previous act, omission or negligence of Tenant under such Sublease, (ii) be subject to any counterclaim, defense or offset not expressly provided for in such Sublease, (iii) be bound by any previous modification or amendment of such Sublease or by any previous payment of more than one month’s rent and additional rent which shall be payable as provided in the Sublease, (iv) be obligated to repair the subleased space or the Buildings or any part thereof in the event of casualty or condemnation except as otherwise required herein, or (v) be obligated to perform any work in the subleased space beyond the requirements of this Lease.

15.11 Easements. Tenant shall not, without the prior written consent of Landlord (in Landlord’s sole and absolute discretion), impose any easements or similar encumbrances upon the Premises or any part thereof.

16. DEFAULT

16.1 Event of Default. The occurrence of any of the following shall be an “Event of Default”:

(a) Failure on the part of Tenant to pay any part of the Base Rent or Additional Rent, or any other sums of money that Tenant is required to pay under this Lease where such failure continues for a period of five (5) business days after written notice of default from Landlord to Tenant; provided, however, that Landlord shall not be required to provide such notice more than three (3) times during any twenty-four (24) month period during the Term with respect to non-payment of Base Rent or Additional Rent payable to Landlord, the third such non-payment constituting default without requirement of notice. Landlord’s notice to Tenant pursuant to this subsection shall be deemed to be the notice required under California Code of Civil Procedure Section 1161.

(b) Failure (i) on the part of Tenant to comply with the obligations under Section 4.7 which failure, unless otherwise provided in Section 4.7, continues for a

period of ten (10) days after written notice from Landlord or (ii) on the part of either or both of the SGI Parties to timely pay any amounts due and owing or otherwise perform under the indemnity provisions of the Purchase Agreements or the Ground Lease Assignments which failure continues for a period of ten (10) days after written notice from Landlord.

(c) Failure of Tenant to perform any other covenant, condition or requirement of this Lease when such failure shall continue for a period of thirty (30) days; provided that if the nature of the default is such that more than thirty (30) days are reasonably required for its cure, then an Event of Default shall not be deemed to have occurred if Tenant shall commence such cure within said thirty (30) day period and thereafter diligently and continuously prosecute such cure to completion and shall complete such cure within one hundred twenty (120) days after such failure shall first occur. Landlord’s notice to Tenant pursuant to this subsection shall be deemed to be the notice required under California Code of Civil Procedure Section 1161.

(d) The abandonment of the entire Premises by Tenant.

(e) Tenant shall admit in writing its inability to pay its debts generally as they become due, file a petition in bankruptcy, insolvency, reorganization, dissolution or liquidation under any law or statute of any government or any subdivision thereof either now or hereafter in effect, make an assignment for the benefit of its creditors, consent to or acquiesce in the appointment of a receiver of itself or of the whole or any substantial part of the Premises.

(f) A court of competent jurisdiction shall enter an order, judgment or decree appointing a receiver of Tenant or of the whole or any substantial part of the Premises and such order, judgment or decree shall not be vacated, set aside or stayed within thirty (30) days after the date of entry of such order, judgment, or decree, or a stay thereof shall be thereafter set aside.

(g) A court of competent jurisdiction shall enter an order, judgment or decree approving a petition filed against Tenant under any bankruptcy, insolvency, reorganization, dissolution or liquidation law or statute of the federal or state government or any subdivision of either now or hereafter in effect, and such order, judgment or decree shall not be vacated, set aside or stayed within thirty (30) days from the date of entry of such order, judgment or decree, or a stay thereof shall be thereafter set aside.

(h) The occurrence of (i) the acceleration of the obligations of Tenant under any Indebtedness or other obligations under which it is liable for more than $20,000,000 or (ii) the maturity of $20,000,000 or more of Indebtedness of Tenant by its terms which has not been paid or (iii) the entry of any judgment against Tenant for $20,000,000 or more which has not been vacated or appealed and stayed; provided that for the purposes of clauses (i) and (ii), the term indebtedness shall not include indebtedness for the deferred purchase price of property or services.

(i) The occurrence of an Event of Default under either of the Other Lasses.

16.2 Remedies. Upon the occurrence of an Event of Default, Landlord shall have the following rights and remedies:

(a) The right to terminate this Lease upon written notice to Tenant, in which event Tenant shall immediately surrender possession of the Premises in accordance with Article 20.

(b) The right to bring a summary action for possession of the Premises.

(c) The rights and remedies described in California Civil Code Section 1951.2, including without limitation the right to recover from Tenant all Rent due through the date this Lease terminates (with interest at the Interest Rate until paid), plus the present worth of the Rent payable hereunder for the balance of the Term, plus any amount necessary to compensate Landlord for the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom which includes, without limitation, (i) the unamortized portion of any brokerage or real estate agent’s commissions paid in connection with the execution of this Lease, (ii) any direct costs or expenses incurred by Landlord in recovering possession of the Premises, maintaining or preserving the Premises after such default, (iii) preparing the Premises for reletting to a new tenant, (iv) any repairs or alterations to the Premises for such reletting, (v) leasing commissions, architect’s fees and any other costs necessary or appropriate either to relet the Premises or, if reasonably necessary in order to relet the Premises, to adapt them to another beneficial use by Landlord and (vi) such amounts in addition to or in lieu of the foregoing as may be permitted from time to time by Applicable Law to the extent that such payment would not result in a duplicative recovery.

(d) The rights and remedies described in California Civil Code Section 1951.4 which allow Landlord to continue this Lease in effect and to enforce all of Landlord’s rights and remedies under this Lease, including the right to recover Base Rent, Additional Rent and other charges payable hereunder as they become due. Acts of maintenance or preservation, efforts to relet the Premises or the appointment of a receiver upon Landlord’s initiative to protect its interest under this Lease shall not constitute a termination of Tenant’s right to possession.

(e) The right and power, as attorney-in-fact for Tenant, to sublet the Premises, to collect rents from all subtenants and to provide or arrange for the provision of all services and fulfill all obligations of Tenant under any permitted subleases. Landlord is hereby authorized on behalf of Tenant, but shall have absolutely no obligation, to provide such services and fulfill such obligations and to incur all such expenses and costs as Landlord deems necessary. Landlord is hereby authorized, but not obligated, to relet the Premises or any part thereof on behalf of Tenant, to incur such expenses as may be necessary to effect a

relet and make said relet for such term or terms, upon such conditions and at such rental as Landlord in its reasonable discretion may deem proper. Tenant shall be liable immediately to Landlord for all costs and expenses Landlord incurs in reletting the Premises including, without limitation, brokers’ commissions, expenses of remodeling the Premises required by the reletting, and the cost of collecting rents and fulfilling the obligations of Tenant to any subtenant. If Landlord relets the Premises or any portion thereof, such reletting shall not relieve Tenant of any obligation hereunder, except that Landlord shall apply the rent or other proceeds actually collected by it as a result of such reletting against any amounts due from Tenant hereunder to the extent that such rent or other proceeds compensate Landlord for the nonperformance of any obligation of Tenant hereunder. Such payments by Tenant shall be due at such times as are provided elsewhere in this Lease, and Landlord need not wait until the termination of this Lease, by expiration of the Term or otherwise, to recover them by legal action or in any other manner. Landlord may execute any sublease made pursuant to this Section in its own name, and the tenant thereunder shall be under no obligation to see to the application by Landlord of any rent or other proceeds, nor shall Tenant have any right to collect any such rent or other proceeds. Landlord shall not by any reentry or other act be deemed to have accepted any surrender by Tenant of the Premises or Tenant’s interest therein, or be deemed to have otherwise terminated this Lease, or to have relieved Tenant of any obligation hereunder, unless Landlord shall have given Tenant express written notice of Landlord’s election to do so as set forth herein.

(f) The right to enjoin, and any other remedy or right now or hereafter available to a Landlord against a defaulting tenant under the laws of the State of California or the equitable powers of its courts, and not otherwise specifically reserved herein.

(g) If this Lease provides for a postponement of deferral of any Rent, or for commencement of payment of Rent to a date later than the Commencement Date, or for a period of “free” Rent or any other Rent concession (collectively, “Abated Rent”), the right upon an Event of Default to demand immediate payment of the value of the Abated Rent.

16.3 Cumulative Remedies. The various rights and remedies reserved to Landlord, including those not specifically described herein, shall, to the extent that the exercise of such right and/or remedy does not result in a duplicative recovery, be cumulative and shall be in addition to every other right or remedy provided for in this Lease or now or hereafter existing at law or in equity and the exercise of the rights or remedies provided for in this Lease or now or hereafter existing at law or in equity shall not preclude the simultaneous or later exercise by Landlord of any or all other rights and remedies.

16.4 Waiver of Redemption by Tenant. Tenant hereby waives any right to redeem, by order or judgment of any court or by any legal process or writ, Tenant’s right of occupancy of the Premises after any termination of this Lease.

16.5 Landlord’s Right to Cure. If Tenant shall fail or neglect to do or perform any covenant or condition required under this Lease and such failure shall not be cured within any applicable grace period, Landlord may, without waiving such default, on five (5) business days notice to Tenant, but shall not be required to, make any payment payable by Tenant hereunder, discharge any lien, take out, pay for and maintain any insurance required hereunder, or do or perform or cause to be done or performed any such other act or thing (entering upon the Premises for such purposes, if Landlord shall so elect), and Landlord shall not be or be held liable or in any way responsible for any loss, disturbance, inconvenience, annoyance or damage resulting to Tenant on account thereof. Tenant shall repay to Landlord within five (5) business days following demand the entire out-of-pocket cost and expense incurred by Landlord in connection with the cure, including, without limitation, compensation to the agents, consultants and contractors of Landlord and reasonable attorneys’ fees and expenses. Landlord shall also impose a thirty percent (30%) administrative fee to compensate Landlord for the cost of performing on behalf of Tenant. Landlord may act upon shorter notice or no notice at all if necessary in Landlord’s reasonable judgment to meet an emergency situation to protect Landlord’s interest in the Premises. Landlord shall not be required to inquire into the correctness of the amount of validity or any tax or lien that may be paid by Landlord and Landlord shall be duly protected in paying the amount of any such tax or lien claimed and in such event Landlord also shall have the full authority, in Landlord’s sole judgment and discretion and without prior notice to or approval by Tenant, to settle or compromise any such lien or tax. Any act or thing done by Landlord pursuant to the provisions of this Section shall not be or be construed as a waiver of any such failure by Tenant, or as a waiver of any term, covenant, agreement or condition herein contained or of the performance thereof.

16.6 Landlord’s Default. Landlord shall be in default under this Lease if Landlord fails to perform obligations required of Landlord within thirty (30) days after written notice by Tenant to Landlord and to any Leasehold Mortgagee or Prior Lessor whose name and address shall have heretofore been furnished to Tenant in writing, specifying wherein Landlord has failed to perform such obligations; provided, however, that if the nature of Landlord’s obligations is such that more than thirty (30) day are required for performance, then Landlord shall not be in default if Landlord commences performance within such thirty (30) day period and thereafter diligently prosecutes the same to completion. Tenant shall be entitled to actual (but not consequential) damages in the event of an uncured default by Landlord, but the provisions of Article 18 shall apply to any Landlord default and Tenant shall not have the right to terminate this Lease as a result of a Landlord default.

16.7 Survival. The provisions of this Article 16 shall survive termination of this Lease.

17. LANDLORD’S RESERVED RIGHTS

17.1 Control of Common Area. Landlord reserves the right, at any time and from time to time, to make alterations, additions, repairs or improvements to all or any part of the Buildings (including the Structural Components and Building Systems), the Common Area and the Property; provided, however, that Landlord shall not materially and adversely affect Tenant’s use of the Premises or its rights of access and parking and not unreasonably interfere with Tenant’s business or properties. Landlord may make changes at any time and from time to time in the size, shape, location, use and extent of the Common Area, and no such change shall entitle Tenant to any abatement of rent or damages; provided, however, that Landlord shall not to materially and adversely affect Tenant’s use of the Premises or its rights of access and parking and not unreasonably interfere with Tenant’s business or properties. Except as otherwise provided herein, Landlord shall at all times during the Term have control of the Structural Components and the Common Area, and may at any time and from time to time during the Term restrain any use or occupancy of the Common Area except as authorized by the Rules and Regulations. Landlord may temporarily close any portion of the Common Area for repairs or alterations, to prevent a dedication or the accrual of prescriptive rights, or for any other reason deemed sufficient by Landlord; provided, however, that Landlord shall not to materially and adversely affect Tenant’s use of the Premises or its rights of access and parking and not unreasonably interfere with Tenant’s business or properties. Tenant’s rights in and to the Common Area shall at all times be subject to the rights of Landlord and Tenant shall keep the Common Area free and clear of any obstructions created or permitted by Tenant or resulting from Tenant’s operations.

17.2 Access. Landlord reserves (for itself and its agents, consultants, contractors and employees) the right to enter the Premises at all reasonable times and, except in cases of emergency, after giving Tenant reasonable notice, to inspect the Premises, to supply any service to be provided by Landlord hereunder, to show the Premises to prospective purchasers, mortgagees or tenants (during the last year of the Term), to post notices of nonresponsibility, and to alter, improve or repair the Premises and any portion of any of the Buildings, without abatement of Rent, and may for that purpose erect, use and maintain necessary structures in and through the Premises and the Buildings where reasonably required by the character of the work to be performed. Landlord will comply with legal access restrictions applicable to special security areas in the Premises. Landlord shall use reasonable efforts not to unreasonably interfere with Tenant’s use of the Premises. Tenant hereby waives any claim for damages for any injury or inconvenience to or interference with Tenant’s business, any loss of occupancy or quiet enjoyment of the Premises or any other loss occasioned thereby. All locks for all of the doors in, upon and about the Premises, excluding Tenant’s vaults and safes or special security areas (designated in advance in writing by Tenant) shall at all times be keyed to the Buildings master system and Landlord shall at all times have and retain a key with which to unlock all of said doors. Landlord shall have the right to use any and all means that Landlord may deem necessary or proper to open said doors in an emergency in order to obtain entry to any portion of the

Premises, and any entry to the Premises or portions thereof obtained by Landlord by any of said means, or otherwise, shall not under any circumstances be construed or deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an eviction, actual or constructive, of Tenant from the Premises or any portion thereof.

17.3 Easements. Subject to the term of covenants and restrictions encumbering the premises, Landlord reserves the right to grant or relocate all easements and rights of way which Landlord in its sole discretion may deem necessary or appropriate, provided that the grant or relocation of easements shall not materially and adversely affect Tenant’s use of the Premises or its rights of access and parking and not unreasonably interfere with Tenant’s business or properties. If any such grant or relocation will incur costs or expenses which are Operating Expenses hereunder, Landlord’s rights under this Section 17.3 shall be exercised in its reasonable discretion.

17.4 Use of Additional Areas. Subject to the provisions of Articles 33, Landlord reserves the exclusive right to use any air space above the Buildings and the Property, the roof and exterior walls of the Buildings and the land beneath the Buildings; provided that such use shall not materially impede Tenant’s use of and access to the Premises.

17.5 Subordination. (a) Leasehold Mortgages. Landlord shall have the right to enter into such Leasehold Mortgages as Landlord shall elect in its sole discretion. This Lease is and shall be subject and subordinate to each and any Leasehold Mortgage and to all advances under any Leasehold Mortgage referred to above, and any restatements, renewals, increases, supplements, modifications, consolidations, spreaders, replacements, substitutions, or extensions of any Leasehold Mortgage, provided that (i) the Leasehold Mortgagee thereunder shall have entered into an SNDA in favor of Tenant in such Leasehold Mortgagee’s customary form and (ii) the Leasehold Mortgage shall provide that, subject to compliance with procedures and conditions customary for construction loan disbursements (including obtaining lien waivers and title insurance endorsements), be made available to Landlord for purposes of a restoration to the extent that Landlord would under Section 19.3 be required to make such proceeds available to Tenant.

(b) Prior Leases. Landlord shall have the right to enter into such Prior Leases and any modifications, amendments, supplements, replacements, extensions, renewals or substitutions thereto or thereof as Landlord shall elect in its sole discretion, provided the same does not result in the imposition on Tenant of any obligations that are materially more onerous than those imposed under this Lease or that otherwise materially adversely affect Tenant. This Lease is and shall be subject and subordinate to each and any Prior Lease provided that the Prior Lessor thereunder shall have entered into an SNDA in favor of Tenant, and to any modifications, amendments, supplements, replacements, extensions, renewals or substitutions thereto or thereof.

(c) Attornment. Tenant agrees that this Lease shall not be terminable by Tenant by reason of any foreclosure of a Leasehold Mortgage or any other

mortgage affecting the Premises, nor by reason of the institution of any suit, action, summary or other proceeding against Landlord or any foreclosure proceeding brought by the holder of any Leasehold Mortgage or other mortgage affecting the Premises to recover possession of the Premises by operation of law or otherwise or by reason of the termination of any Prior Lease and that the same shall not result in the cancellation or termination of this Lease by Tenant or of the obligations of Tenant hereunder. If at any time prior to the expiration of the Term, any Prior Lessor or Leasehold Mortgagee comes into possession of the Premises or a receiver shall be appointed for Landlord’s interest in the Premises, Tenant agrees, at the election and upon demand of any such Prior Lessor or Leasehold Mortgagee in possession, to attorn, from time to time, to any such Prior Lessor or Leasehold Mortgagee or any person acquiring the interest of Landlord as a result of any such Prior Lease termination or as a result of a foreclosure of a Leasehold Mortgage or the granting of a deed or assignment in lieu of foreclosure, upon the then executory terms and conditions of this Lease for the remainder of the Term. The provisions of this Section 17.5 shall inure to the benefit of any such successor Landlord, shall apply notwithstanding that, as a matter of law, this Lease may terminate upon the termination of a Prior Lease or foreclosure of a Leasehold Mortgage, and shall be self-operative upon any such demand, and no further instrument shall be required to give effect to said provisions. Tenant, however, upon demand of any such successor Landlord, shall execute, from time to time, instruments in confirmation of the forgoing provisions of this Section 17.5 reasonably satisfactory to any such successor Landlord and Tenant, acknowledging such attornment and setting forth in the terms and conditions of its tenancy. Nothing contained in this Section shall be construed to impair any right otherwise exercisable by any such successor Landlord.

(d) Leasehold Mortgagee Cure Rights. In the event of any act or omission by Landlord which would give Tenant the right to terminate this Lease or to claim a partial or total eviction, pursuant to the terms of this Lease, if any, Tenant will not exercise any such right until (i) it has given written notice of such act or omission to the holder(s) of any Leasehold Mortgages to which this Lease shall be subordinate, whose name and address shall previously have been furnished to Tenant, by delivering such notice of such act or omission addressed to such holders at the last address so furnished, and (ii) in the case of any such act, omission or default that can be cured by the payment of money, until thirty (30) days shall have elapsed following the giving of such notice, or (ii) in the case of any other such act, omission or default, until a reasonable period for remedying such act, omission or default shall have elapsed following the giving of such notice and following the time when any such holder shall have become entitled under its Leasehold Mortgage to remedy the same, including such time as may be necessary to acquire possession of the Premises if possession is necessary to effect such cure, provided any such holder with reasonable diligence, shall (x) pursue such remedies as are available to it under its Leasehold Mortgage so as to be able to remedy the act, omission or default, and (y) thereafter shall have commenced and continued to remedy such act, omission or default or cause the same to be remedied; provided, however, that the agreements of Tenant contained in this Section 17.5 shall be subject to the terms of any SNDA between Tenant and any such holder(s).

(e) Amendments Requested by Leasehold Mortgagee. If, in connection with obtaining any financing or refinancing or any increases, restatements, renewals, supplements, modifications, consolidations, replacements, substitutions or extensions thereof, a prospective or existing Leasehold Mortgagee and/or holder of an interest in any loan secured by a Leasehold Mortgage, as the case may be, shall request amendments to or modifications of this Lease as a condition to the same, Tenant shall promptly execute such amendments or modifications upon demand as long as (i) the modifications do not affect the Rent or the Term or the Letter of Credit and (ii) such amendments or modifications do not otherwise materially increase Tenant’s obligations or materially diminish Tenant’s rights hereunder. In addition, Tenant shall deliver any financial statements or other information requested by Landlord (or any prospective or existing lender) in order to obtain such financing or refinancing, provided that Tenant shall not be required to disclose any non-public information relating to Tenant. Furthermore, Tenant, at Tenant’s expense, shall cause counsel reasonably acceptable to a prospective Leasehold Mortgagee to deliver legal opinions reasonably required by such prospective Leasehold Mortgagee relating to the due authorization, execution and delivery of this Lease and any amendments thereto, the validity and enforceability of such agreements, and other customary matters.

18. LIMITATION OF LANDLORD’S LIABILITY

18.1 Limitation. Landlord shall not be responsible for or liable to Tenant and Tenant hereby releases Landlord, waives all claims against Landlord and assumes the risk for any injury, loss or damage to any person or property in or about the Premises, the Buildings or the Property by or from any cause whatsoever (other than Landlord’s gross negligence or willful misconduct) including, without limitation, (a) acts or omissions of persons occupying adjoining premises, (b) theft or vandalism, (c) burst, stopped or leaking water, gas, sewer or steam pipes, (d) loss of utility service, (e) accident, fire or casualty, (f) nuisance, and (g) work done by Landlord in the Property, the Buildings, the Common Area or the Premises; notwithstanding the foregoing, Landlord shall remain liable for compliance with its express obligations hereunder. Even if due to the gross negligence or willful misconduct of Landlord, Tenant hereby waives any claim for consequential damages in connection therewith. There shall be no abatement of Rent and no liability of Landlord by reason of any injury to or interference with Tenant’s business or inconvenience or annoyance to Tenant arising from the making of any repairs, alterations or improvements to any portion of the Buildings or to fixtures, appurtenances and equipment therein, other than such liability as may be imposed upon Landlord by law or for Landlord’s negligence or willful misconduct. No interference with Tenant’s operations in the Premises shall constitute a constructive or other eviction of Tenant. Tenant hereby waives and releases any right it may have to make repairs at Landlord’s expense under Sections 1941 and 1942 of the California Civil Code, or under any similar law, statute or ordinance now or hereafter in effect other than as expressly provided in this Lease.

18.2 Sale of Property. It is agreed that Landlord may at any time sell, assign or transfer its interest as landlord in and to this Lease, and may at any time sell, assign

or transfer its interest in and to the Property. In the event of any transfer of Landlord’s interest in the Property, the transferor shall be automatically relieved of any and all of Landlord’s obligations and liabilities accruing from and after the date of such transfer; provided that the transferee assumes all of Landlord’s obligations under this Lease. Tenant hereby agrees to attorn to Landlord’s assignee, transferee, or purchaser from and after the date of notice to Tenant of such assignment, transfer or sale, in the same manner and with the same force and effect as though this Lease were made in the first instance by and between Tenant and the assignee, transferee or purchaser.

18.3 No Personal Liability. In the event of any default by Landlord hereunder, Tenant shall look only to Landlord’s interest in the Property and rents therefrom and any available insurance proceeds for the satisfaction of Tenant’s remedies, and no other property or assets of Landlord or any trustee, partner, member, officer or director thereof, disclosed or undisclosed, shall be subject to levy, execution or other enforcement procedure for the satisfaction of Tenant’s remedies under or with respect to this Lease.

18.4 Landlord’s Consent or Approval; Limitation on Damages. (a) In the event that Tenant shall claim or assert that Landlord has violated or failed to perform a covenant of Landlord not to unreasonably withhold, delay or condition Landlord’s consent or approval, or in any case where Landlord’s reasonableness in exercising its judgment is in issue, Tenant’s sole remedy shall be an action for specific performance, declaratory judgment or injunction, and in no event shall Tenant be entitled to any money damages for a breach of such covenant, and in no event shall Tenant claim or assert any claims for money damages in any action or by way of set-off, defense or counterclaim, and Tenant hereby specifically waives the right to any money damages, set-off, defense, counterclaim or other remedies; provided, however, that Tenant shall have the right to determine any dispute between Landlord and Tenant as to whether Landlord has violated or failed to perform a covenant of Landlord not unreasonably to withhold, delay or condition Landlord’s consent or where Landlord’s reasonableness in exercising its judgment is in issue, or any other dispute which by the express terms of this Lease provides that it shall be resolved by arbitration, in each case by arbitration in the County of Santa Clara, California in accordance with the provisions of this Section 18.4. Within ten (10) days next following the giving of any notice by Tenant to Landlord stating that it wishes such dispute to be so determined, Landlord and Tenant shall each give notice to each other setting forth the name and address of an arbitrator designated by the party giving notice. If either party shall fail to give notice of such designation within said ten (10) days, then the arbitrator chosen by the other side shall make the determination alone. The two arbitrators shall designate a third arbitrator. If the two arbitrators shall fail to agree upon the designation of a third arbitrator within five (5) days after the designation of the second arbitrator, then either party may apply to any court having jurisdiction, requesting the designation of such arbitrator. Notwithstanding the foregoing, in the event of disputes relating to less than $100,000, one (1) arbitrator shall be selected in accordance with the then prevailing Commercial Rules of the American Arbitration Association. All arbitrators shall be persons who shall have had at least ten (10) years experience arbitrating or mediating disputes relating to California office leases or who shall otherwise be approved by the

parties, and shall not be financially or contractually related to Landlord or Tenant. The three arbitrators shall conduct such hearings as they deem appropriate, making their determination in writing and give notice to Landlord and Tenant; the concurrence of any two of said arbitrators shall be binding upon Landlord and Tenant. The sole question to be determined shall be whether or not Landlord has unreasonably withheld or delayed its consent or approval, and the sole remedy shall be the determination that such consent or approval must be granted. The determination in any arbitration held pursuant to this Section shall be final and binding upon Landlord and Tenant. Each party shall pay its own counsel fees and expenses, if any, in connection with any arbitration under this Section 18.4, including the expenses and fees of any arbitrator selected by it in accordance with provisions of this Section, and the parties shall share all other expenses and fees of any such arbitration, provided that the foregoing shall not prohibit the arbitrators from determining that the prevailing party shall be entitled to recover all costs and expenses from the non-prevailing party. The arbitrators shall be bound by the provisions of this Lease, and shall not add to, subtract from or otherwise modify such provisions.

(b) In no event shall Tenant have the right to seek or recover from Landlord any consequential damages on account of any claim or matter arising out of or relating to this Lease of the Premises and Tenant hereby irrevocably waives any right which it might otherwise have to seek or receive any such consequential damages.

19. DESTRUCTION

19.1 Landlord’s Obligation. (a) If the Premises or the Common Area or any portion thereof (whether or not the Premises are affected) are damaged by fire or other casualty (“Casualty”) and Tenant shall be restoring the same in accordance with Section 19.3, Landlord shall make available to Tenant any insurance proceeds payable on account of such Casualty at such time and in accordance with such procedures as are provided in any Leasehold Mortgage (or if there shall be no Leasehold Mortgage, in accordance with such procedures as Landlord shall reasonably determine are customary for leasehold mortgages) and in compliance with the Ground Lease, which proceeds shall be used by Tenant only to fulfill restoration obligations hereunder and for no other purpose.

(b) If all or any part of the Premises shall be rendered Untenantable by reason of a Casualty, the Base Rent and the Additional Rent shall be abated in the proportion that the Untenantable area of the Premises bears to the total area of the Premises, for the period from the date of the Casualty to the earlier of (i) the date the Premises is no longer Untenantable (provided that, if the Premises would no longer have been Untenantable at an earlier date but for Tenant having failed diligently to prosecute repairs or restoration required of Tenant under this Lease, then the Premises shall be deemed to no longer be Untenantable on such earlier date and the abatement shall cease) or (ii) the date Tenant or any subtenant reoccupies any Untenantable portion of the Premises for the ordinary conduct of business (in which case the Base Rent and the Additional Rent allocable to such reoccupied portion shall be payable by Tenant from the date of such occupancy).

Pending resolution of any dispute with respect to the period or amount of such abatement, Tenant shall pay Rent in accordance with Landlord’s determination. Notwithstanding the foregoing, if by reason of any act or omission by Tenant, any subtenant or any of their respective partners, directors, officers, servants, employees, agents or contractors, Landlord or any Leasehold Mortgagee shall be unable to collect all of the insurance proceeds (including, without limitation, rent insurance proceeds) applicable to the Casualty, then, without prejudice to any other remedies which may be available against Tenant, there shall be no abatement of Rent.

(c) Landlord shall not be liable for any inconvenience or annoyance to Tenant or injury to the business of Tenant resulting in any way from such damage by Casualty or the repair thereof. Landlord shall not be obligated to carry insurance of any kind on Tenant’s Property or any Alterations or any other improvements made at Tenant’s sole cost and expense, and Landlord shall not be obligated to repair any damage thereto or replace the same.

19.2 Termination Option. Landlord shall notify Tenant within sixty (60) days after the date of damage whether or not the requirements for repairs, reconstruction and restoration by Tenant described in Section 19.3 are met. If such requirements are not met, Landlord shall have the option, exercisable within sixty (60) days after the date of such damage either to: (a) notify Tenant of Landlord’s election to repair such damage, in which event this Lease shall continue in full force and effect (unless terminated by Tenant as provided below), or (b) notify Tenant of Landlord’s election to terminate this Lease as of the date of the damage. If such notice to terminate is given by Landlord, this Lease shall terminate as of the date of such damage. If Landlord notifies Tenant of its intention to repair Casualty damages and Landlord reasonably estimates that such repairs cannot be completed within eighteen (18) months, Tenant shall have the right to terminate this Lease by delivering fifteen (15) days’ written notice to Landlord.

19.3 Tenant Obligations. Subject to Section 19.2, if the Premises or the Buildings or any portion thereof (whether or not the Premises are affected) are damaged by Casualty, Tenant shall, at Tenant’s sole cost and expense, repair, reconstruct and restore the same promptly, with diligence and continuity and in accordance with the requirements of Section 8.2 and the requirements of Article 10 for Alterations; provided that (i) such repairs can be made under the laws and regulations of the federal, state and local governmental authorities having jurisdiction within twelve (12) months after the date of such damage (or in the case of damage occurring during the last twelve (12) months of the Term, provided that such repairs can be made within ninety (90) days after the date of such damage), (ii) such repairs are fully covered (except for any deductible) by the proceeds of insurance maintained by Landlord or Tenant, and (iii) the damage does not affect more than fifty percent (50%) of the assessed value of the Buildings. If Tenant is required to repair, reconstruct or restore the Premises after any damage or destruction, Tenant shall be responsible at its own expense for the repair and replacement of Tenant’s Property and any Alterations which Tenant elects to replace. Tenant hereby waives the provisions of any statute or law that may be in effect at

the time of the occurrence of any such damage or destruction, under which a lease is automatically terminated or a tenant is given the right to terminate a lease upon such an occurrence.

19.4 No Claim. Except as provided in Section 19.1, Tenant shall have no interest in or claim to any portion of the proceeds of any insurance or self-insurance maintained by Landlord.

19.5 No Damages. Tenant shall not be entitled to any damages by reason of any inconvenience or loss sustained by Tenant as a result of any repairs, reconstruction or restoration of any damage or destruction to the Premises under any of the provisions of this Article 19. Except as expressly provided in Section 19.1 or 19.4, there shall be no reduction, change or abatement of any rental or other charge payable by Tenant to Landlord hereunder, or in the method of computing, accounting for or paying the same. Each party hereby waives the provisions of Section 1932(2) and Section 1933(4) of the California Civil Code, or any other statute or law that may be in effect at the time of a casualty under which a lease is automatically terminated or a tenant is given the right to terminate a lease due to a casualty other than as provided in Section 19.1.

20. EMINENT DOMAIN

20.1 Taking. If all or any part of the Premises shall be taken as a result of the exercise of the power of eminent domain or any transfer in lieu thereof, this Lease shall terminate as to the part so taken as of the date of taking or as of the date of final judgment, whichever is earlier, and, in the case of a material partial taking of the Premises, Landlord shall have the right to terminate this Lease as to the balance of the Premises by written notice to Tenant within thirty (30) days after such date. If any material part of the Common Area, the Buildings or the Property shall be taken as a result of the exercise of the power of eminent domain or any transfer in lieu thereof, whether or not the Premises are affected, Landlord shall have the right to terminate this Lease by written notice to Tenant within thirty (30) days of the date of taking. If there shall be a taking of the Property of such scope that the untaken part of the Property would in Tenant’s reasonable judgment be uneconomic to operate, then Tenant may terminate this Lease and the term and estate granted hereby by giving notice to Landlord within thirty (30) days after the date of taking of possession by the condemning authority.

20.2 Award. In the event of any taking, Landlord shall be entitled to any and all compensation, damages, income, rent, awards, or any interest therein whatsoever which may be paid or made in connection therewith, and Tenant shall assign to Landlord any right to compensation or damages for the condemnation of its leasehold interest; provided that Tenant may file a claim for (a) Tenant’s relocation expenses, (b) the taking of Tenant’s Property, and (c) the loss of Tenant’s goodwill.

20.3 Partial Taking. In the event of a partial taking of the Premises which does not result in a termination of this Lease (other than with respect to the taken portion of the Premises), the Base Rent and Operating Expenses shall be adjusted as follows:

(a) During the period between the date of the partial taking and the completion of any necessary repairs, reconstruction or restoration, Tenant shall be entitled to a reduction of Base Rent and Operating Expenses by a proportionate amount based on Rentable Area taken; and

(b) Upon completion of said repairs, reconstruction or restoration, and thereafter throughout the remainder of the Term, the Base Rent and Operating Expenses shall be recalculated based on the remaining total number of square feet of Rentable Area of the Premises.

20.4 Temporary Taking. Notwithstanding any other provision of this Article, if a taking occurs with respect to all or any portion of the Premises for a period of twelve (12) months or less, this Lease shall remain unaffected thereby and Tenant shall continue to pay Base Rent and Additional Rent and to perform all of the terms, conditions and covenants of this Lease, provided that Tenant shall have the right to terminate this Lease if the taking continues beyond twelve (12) months. In the event of any such temporary taking, and if this Lease is not terminated, Tenant shall be entitled to receive that portion of any award which represents compensation for the use or occupancy of the Premises during the Term up to the total Base Rent and Additional Rent owing by Tenant for the period of the taking, and Landlord shall be entitled to receive the balance of any award.

20.5 Sale in Lieu of Condemnation. A voluntary sale by Landlord of all or any part of the Buildings or the Common Area to any public or quasi-public body, agency or person, corporate or otherwise, having the power of eminent domain, either under threat of condemnation or while condemnation proceedings are pending, shall be deemed to be a taking under the power of eminent domain for the purposes of this Article.

20.6 Waiver. Except as provided in this Article, each party hereto hereby waives and releases any right it may have under any Applicable Law to terminate this Lease as a result of a taking, including without limitation Sections 1265.120 and 1265.130 of the California Code of Civil Procedure, or any similar law, statute or ordinance now or hereafter in effect other than as expressly provided in this Lease.

21. SURRENDER

21.1 Surrender. Upon the Termination Date, Tenant shall surrender the Premises to Landlord in good order and repair, reasonable wear and tear and damage by casualty excepted, free and clear of all letting and occupancies. Subject to Article 10, upon any termination of this Lease, all improvements, except for Tenant’s Property, shall automatically and without further act by Landlord or Tenant, become the property of

Landlord, free and clear of any claim or interest therein by Tenant, and without payment therefore by Landlord.

21.2 Holding Over. Any holding over after the expiration of the Term with the consent of Landlord shall be construed to automatically extend the Term on a month-to-month basis at a Base Rent equal to the greater of (a) two (2) tunes the then-current Base Rent, and (b) one and one-half (1-1/2) times the prevailing rate at which Landlord is then offering space in buildings reasonably determined by Landlord to be comparable to the Buildings, in either case together with an amount estimated by Landlord as Tenant’s Share of Operating Expenses payable under this Lease, and shall otherwise be on the terms and conditions of this Lease to the extent applicable. Any holding over without Landlord’s consent shall entitle Landlord to exercise any or all of its remedies provided in Article 16, notwithstanding that Landlord may elect to accept one or more payments of Base Rent and Operating Expenses from Tenant.

21.3 Quitclaim. At the expiration or earlier termination of this Lease, Tenant shall execute, acknowledge and deliver to Landlord, within ten (10) days after written demand from Landlord to Tenant, any quitclaim deed or other document required by any reputable title company, licensed to operate in the State of California, to remove the cloud or encumbrance created by this Lease from the Property.

22. FINANCIAL STATEMENTS

Tenant shall tender to Landlord within ten (10) business days after receipt of a written request any information reasonably requested by Landlord regarding the financial stability, credit worthiness or ability of Tenant to pay the Rent due under this Lease. Notwithstanding the foregoing, if the Tenant is a Public Company subject to the reporting requirements of the Securities Exchange Act of 1934 (the “Exchange Act”). Tenant shall, in lieu of the foregoing requirements, promptly deliver to Landlord all filings made by or on behalf of Tenant with the Securities Exchange Commission or with any securities exchange. Landlord shall be entitled to rely upon the information provided in determining whether or not to enter into this Lease or for the purpose of any financing or other transaction subsequently undertaken by Landlord. Tenant hereby represents and warrants to Landlord the following: (a) that all documents provided by Tenant to Landlord in connection with the negotiation of this Lease are true and correct copies of the originals, (b) Tenant has not withheld any information from Landlord that is material to Tenant’s credit worthiness, financial condition or ability to perform its obligations hereunder, (c) all information supplied by Tenant to Landlord is true, correct and accurate, and (d) no part of the information supplied by Tenant to Landlord contains any misleading or fraudulent statements.

23. ESTOPPEL CERTIFICATES

Tenant, at any time and from time to time within five (5) business days after receipt of written notice from Landlord, shall execute, acknowledge and deliver to Landlord or to any party designated by Landlord, a certificate of Tenant stating: (a) that Tenant has

accepted the Premises, (b) the Commencement Date and Expiration Date of this Lease, (c) that this Lease is unmodified and in full force and effect (or, if there have been modifications, that same is in full force and effect as modified and stating the modifications), (d) whether or not there are then existing any defenses against the enforcement of any of the obligations of Tenant under this Lease (and, if so, specifying same), (e) whether or not there are then existing any defaults by Landlord in the performance of its obligations under this Lease (and, if so, specifying same), (f) the dates, if any, to which the Base Rent and Operating Expenses have been paid, and (g) any other factual information relating to the rights and obligations under this Lease that may reasonably be required by any of such persons. Failure to deliver such certificate shall constitute an Event of Default. At the request of Tenant, Landlord shall execute, acknowledge and deliver to Tenant a certificate with similar types of information and in the time period set forth above. Failure by Tenant to execute, acknowledge and deliver such certificate within such five (5) business day period shall be conclusive evidence that this Lease is in full force and effect and has not been modified except as may be represented by the requesting party.

24. RULES AND REGULATIONS

24.1 Rules and Regulations. Tenant shall faithfully observe and comply with any rules and regulations and all reasonable modifications thereof and additions thereto from time to time put into effect by Landlord (the “Rules and Regulations”). Landlord shall not enforce such Rules and Regulations in an unreasonable or discriminatory manner. In the event of any conflict between the terms of this Lease and the terms, covenants, agreements and conditions of the Rules and Regulations, this Lease shall control. Notwithstanding the foregoing, so long as Tenant leases 100% of the Premises leased by Tenant hereunder as of the Commencement Date, Landlord shall not impose any Rules and Regulations.

24.2 Signs. Without Landlord’s written consent, which may be given or withheld in Landlord’s sole discretion, Tenant shall not place or permit to be placed on the front of the Premises any sign, picture, advertisement, name, notice, marquee or awning; provided that upon Landlord’s reasonable approval, Tenant shall have the right to place a sign on or adjacent to the entrance doors to Tenant’s Premises identifying Tenant. Landlord hereby consents to the location, size and appearance of Tenant’s signage existing as of the Commencement Date. Landlord hereby reserves the exclusive right to the exterior side walls, rear walls and roof of the Premises.

25. INABILITY TO PERFORM

If Landlord is unable to fulfill or is delayed in fulfilling any of Landlord’s obligations under this Lease, by reason of acts of God, strikes, lockouts, other labor disputes, inability to obtain utilities or materials or by any other reason beyond Landlord’s reasonable control, then no such inability or delay by Landlord shall constitute an actual or constructive eviction, in whole or in part, or entitle Tenant to any abatement or diminution of Base Rent or Additional Rent, or relieve Tenant from any of its obligations under this Lease, or impose any liability upon Landlord, or Landlord’s Agents by reason of inconvenience, annoyance,

interruption, injury or loss to or interference with Tenant’s business or use and occupancy or quiet enjoyment of the Premises or any loss or damage occasioned thereby. If Tenant is unable to fulfill or is delayed in fulfilling any of Tenant’s obligations under this Lease (other than the payment of Rent), by reason of acts of God, strikes, lockouts, other labor disputes, inability to obtain utilities or materials or by any other reason beyond Tenant’s reasonable control, then such inability or delay by Tenant shall excuse the performance of Tenant for a period equal to the duration of such prevention, delay or stoppage. Tenant hereby waives and releases any right to terminate this Lease under Section 1932(l) of the California Civil Code, or any similar law, statute or ordinance now or hereafter in effect.

26. NOTICES

Notices or other communications given or required to be given under this Lease shall be effective only if rendered or given in writing, sent by certified mail with a return receipt requested, or delivered in person or by reputable overnight courier (e.g., Federal Express, DHL, etc.) or by telecopier or facsimile (with confirmation by one of the other methods specified herein): (a) to Tenant (i) at the Premises and at the address specified in Article 1, or (ii) at the place where Tenant designates subsequent to Tenant’s vacating, deserting, abandoning or surrendering the Premises; or (b) to Landlord at Landlord’s address set forth in Article 1; or (c) to such other address as either Landlord or Tenant may designate as its new address for such purpose by notice given to the other in accordance with the provisions of this Article. Any such notice or other communication shall be deemed to have been rendered or given five (5) days after the date mailed, if sent by certified mail, or upon the date of delivery in person or by courier, or when delivery is attempted but refused.

27. QUIET ENJOYMENT

Landlord covenants that so long as an Event of Default by Tenant is not in existence, upon paying the Base Rent and Additional Rent, Tenant shall peaceably and quietly enjoy the Premises, subject to the terms and provisions of this Lease.

28. NO RENT ABATEMENT

No abatement, diminution or reduction of rent, charges or other compensation shall be claimed by or allowed to Tenant, or any persons claiming under Tenant, under any circumstances, whether for inconvenience, discomfort, interruption of business or otherwise, arising from the making of Alterations or repairs to any improvements now on or which may hereafter be erected on the Premises, by virtue or because of any present or future Legal Requirements or by virtue or arising from, and during, the restoration of the Premises after the destruction or damage thereof by Casualty or other cause or the taking or condemnation of the Premises (except as otherwise expressly provided for in Article 19 or 20) or arising from any other cause or reason.

29. AUTHORITY

If Tenant is a corporation or a partnership, Tenant represents and warrants as follows: Tenant is an entity as identified in Article 1, duly formed and validly existing and in good standing under the laws of the state of organization specified in Article 1 and qualified to do business in the State of California. Tenant has the power, legal capacity and authority to enter into and perform its obligations under this Lease and no approval or consent of any person is required in connection with the execution and performance hereof.
