ARTICLE 2

LEASED PREMISES, TERM AND POSSESSION

2.1 Demise Of Leased Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord for Tenant’s own use in the conduct of Tenant’s business and not for purposes of speculating in real estate, for the Lease Term and upon the terms and subject to the conditions of this Lease, that certain interior space described in Article 1 as the Leased Premises, reserving and excepting to Landlord the right to seventy five percent (75%) of all assignment consideration and excess rentals as provided in Article 7 below. Tenant’s lease of the Leased Premises, together with the appurtenant right to use the Outside Areas as described in Paragraph 2.2 below, shall be conditioned upon and be subject to the continuing compliance by Tenant with (i) all the terms and conditions of this Lease, (ii) all Laws governing the use of the Leased Premises and the Property, (iii) all Private Restrictions, easements and other matters now of public record respecting the use of the Leased Premises and Property, and (iv) all reasonable rules and regulations from time to time established by Landlord.

2.2 Right To Use Outside Areas. As an appurtenant right to Tenant’s right to the use and occupancy of the Leased Premises, Tenant shall have the right to use the Outside Areas in conjunction with its use of the Leased Premises solely for the purposes for which they were designated and intended and for no other purposes whatsoever. Tenant’s right to so use the Outside Areas shall be subject to the limitations on such use as set forth in Article 1 and shall terminate concurrently with any termination of this Lease.

2.3 Lease Commencement Date And Lease Term. The term of this Lease shall begin, and the Lease Commencement Date shall be deemed to have occurred, on the Lease Commencement Date, as set forth in Article 1 (the “Lease Commencement Date”). The term of this Lease shall in all events end on the Lease Expiration Date (as set forth in Article 1). The Lease Term shall be that period of time commencing on the Lease Commencement Date and ending on the Lease Expiration Date (the “Lease Term”).

2.4 Delivery Of Possession. Landlord shall deliver to Tenant possession of the Leased Premises on the Lease Commencement Date. If Landlord is unable to so deliver possession of the Leased Premises to Tenant on or before the Lease Commencement Date, Landlord shall not be in default under this Lease, nor shall this Lease be void, voidable or cancelable by Tenant until the lapse of ninety (90) days after the Intended Commencement Date (the “delivery grace period”); however, if Landlord’s inability to so deliver the Leased Premises to Tenant is caused by the existing tenant’s hold over in the Leased Premises beyond the term of its current lease or by Landlord’s gross negligence or willful misconduct, the Lease Commencement Date shall not be deemed to have occurred until the

actual date of delivery. Additionally, the delivery grace period above set forth shall be extended for such number of days as Landlord may be delayed in delivering possession of the Leased Premises to Tenant by reason of Force Majeure or the action or inaction of Tenant. If Landlord is unable to deliver possession of the Leased Premises in the agreed condition to Tenant within the described delivery grace period (including any extension thereof by reason of Force Majeure or the actions or inactions of Tenant), then Tenant’s sole remedy shall be to terminate this Lease in which case Landlord shall return to Tenant all Prepaid Rent and the Security Deposit, and in no event shall Landlord be liable in damages to Tenant for such delay. Tenant may not terminate this Lease at any time after the date Landlord notifies Tenant that the Leased Premises have been put into the agreed condition and are available for delivery to Tenant, unless Landlord’s notice is not given in good faith. If Landlord makes the Leased Premises available to Tenant prior to the Lease Commencement Date, Tenant may occupy the Leased Premises prior to the Lease Commencement Date for the purposes of installing furniture, fixtures and equipment, provided that Tenant shall be responsible for Additional Rent during such period and Tenant shall comply with all other provisions of this Lease (other than the payment of Base Monthly Rent).

2.5 Performance Of Improvement Work; Acceptance Of Possession. Landlord agrees to deliver in good working order and in compliance with all Laws applicable to the Leased Premises on the Lease Commencement Date, the roof surface and all existing electrical, mechanical, plumbing, lighting, heating, ventilating and air conditioning systems within the Leased Premises. The Leased Premises shall be delivered to Tenant in a broom clean condition, with all of the current tenant’s furnishings, equipment, and materials removed. It is agreed that by occupying the Leased Premises, Tenant formally accepts same and acknowledges that the Leased Premises are in the condition called for hereunder. Landlord hereby represents and warrants that it has received no notice that the Leased Premises do not comply with applicable Laws.

2.6 Surrender Of Possession. Immediately prior to the expiration or upon the sooner termination of this Lease, Tenant shall remove all of Tenant’s signs from the exterior of the Building and shall remove all of Tenant’s equipment, trade fixtures, furniture, supplies, wall decorations and other personal property from within the Leased Premises, the Building and the Outside Areas, and shall vacate and surrender the Leased Premises, the Building, the Outside Areas and the Property to Landlord in the same condition, broom clean, as existed at the Lease Commencement Date, reasonable wear and tear (and damage from casualty, which is covered by Article 10 hereof) excepted. Tenant shall repair all damage to the Leased Premises, the exterior of the Building and the Outside Areas caused by Tenant’s removal of Tenant’s property. Tenant shall patch and refinish, to Landlord’s reasonable satisfaction, all penetrations made by Tenant or its employees to the floor, walls or ceiling of the Leased Premises, whether such penetrations were made with Landlord’s approval or not. Tenant shall repair or replace all stained or damaged ceiling tiles, wall coverings and floor coverings to the reasonable satisfaction of Landlord. Tenant shall repair all damage caused by Tenant to the exterior surface of the Building and the paved surfaces of the Outside Areas and, where necessary, replace or resurface same. Additionally, to the extent that Landlord shall have notified or is deemed to have notified Tenant in writing at the time the improvements were completed that it desired to have certain improvements made by Tenant or at the request of Tenant removed at the expiration or sooner termination of the Lease, Tenant shall, upon the expiration or sooner termination of the Lease, remove any such improvements constructed or installed by Landlord or Tenant and repair all damage caused by such removal. If the Leased Premises, the Building, the Outside Areas and the Property are not surrendered to Landlord in the condition required by this paragraph at the expiration or sooner termination of this Lease, Landlord may, at Tenant’s expense, so remove Tenant’s signs, property and/or improvements not so removed and make such repairs and replacements not so made or hire, at Tenant’s expense, independent contractors to perform such work. Tenant shall be liable to Landlord for all costs incurred by Landlord in returning the Leased Premises, the Building and the Outside Areas to the required condition, together with interest on all costs so incurred from the date paid by Landlord at the then maximum rate of interest not prohibited or made usurious by law until paid. Tenant shall pay to Landlord the amount of all costs so incurred plus such interest thereon, within ten (10) days of Landlord’s billing Tenant for same. Tenant shall indemnify Landlord against loss or liability resulting from delay by Tenant in surrendering the Leased Premises, including, without limitation, any claims made by any succeeding Tenant or any losses to Landlord with respect to lost opportunities to lease to succeeding tenants.

ARTICLE 3

RENT, LATE CHARGES AND SECURITY DEPOSITS

3.1 Base Monthly Rent. Commencing on the Lease Commencement Date (as determined pursuant to Paragraph 2.3 above) and continuing throughout the Lease Term, Tenant shall pay to Landlord, without prior demand therefor, in advance on the first day of each calendar month, the amount set forth as “Base Monthly Rent” in Article 1 (the “Base Monthly Rent”).

3.2 Additional Rent. Commencing on the Lease Commencement Date (as determined pursuant to Paragraph 2.3 above) and continuing throughout the Lease Term, in addition to the Base Monthly Rent and to the extent not required by Landlord to be contracted for and paid directly by Tenant, Tenant shall pay to Landlord as additional rent (the “Additional Rent”) the following amounts:

(a) An amount equal to all Property Operating Expenses (as defined in Article 13) incurred by Landlord. Payment shall be made by whichever of the following methods (or combination of methods) is (are) from time to time designated by Landlord:

(i) Landlord may forward invoices or bills for such expenses to Tenant, and Tenant shall, no later than ten (10) days prior to the due date, pay such invoices or bills and deliver satisfactory evidence of such payment to Landlord, and/or

(ii) Landlord may ▇▇▇▇ to Tenant, on a periodic basis not more frequently than monthly, the amount of such expenses (or group of expenses) as paid or incurred by Landlord, and Tenant shall pay to Landlord the amount of such expenses within ten days after receipt of a written ▇▇▇▇ therefor from Landlord, and/or

(iii) Landlord may deliver to Tenant Landlord’s reasonable estimate of any given expense (such as Landlord’s Insurance Costs or Real Property Taxes), or group of expenses, which it anticipates will be paid or incurred for the ensuing calendar or fiscal year, as Landlord may determine, and Tenant shall pay to Landlord an amount equal to the estimated amount of such expenses for such year in equal monthly installments during such year with the installments of Base Monthly Rent.

Landlord reserves the right to change from time to time the methods of billing Tenant for any given expense or group of expenses or the periodic basis on which such expenses are billed.

(b) Landlord’s share of the consideration received by Tenant upon certain assignments and sublettings as required by Article 7.

(c) Any legal fees and costs that Tenant is obligated to pay or reimburse to Landlord pursuant to Article 13; and

(d) Any other charges or reimbursements due Landlord from Tenant pursuant to the terms of this Lease.

Notwithstanding the foregoing, Landlord may elect by written notice to Tenant to have Tenant pay Real Property Taxes or any portion thereof directly to the applicable taxing authority, in which case Tenant shall make such payments and deliver satisfactory evidence of payment to Landlord no later than five (5) days before such Real Property Taxes become delinquent.

Tenant may cause an audit of Landlord’s books and records using an independent “Big Six” accounting firm to determine the accuracy of Landlord’s ▇▇▇▇▇▇▇▇ for Property Operating Expenses under this Lease, provided Tenant commences such audit within ninety (90) days after Tenant’s receipt of the year-end statement described in Paragraph 3.3 above setting forth the annual reconciliation of the Property Operating Expenses. If such audit reveals that the actual Property Operating Expenses for any given year were less than the amount that Tenant paid for Property Operating Expenses for any such year, then Landlord shall credit the excess to Tenant’s next payment of Additional Rent. If such audit reveals that the actual Property Operating Expenses for any given year were more than the amount that Tenant paid for Property Operating Expenses for any such year, Tenant shall pay such amount to Landlord within ninety (90) days after completion of the audit. In the event the audit shows that Landlord overcharged Tenant by more than 5% of the actual Property Operating Expenses, Landlord shall pay for the costs of the audit.

3.3 Year-End Adjustments. If Landlord shall have elected to ▇▇▇▇ Tenant for the Property Operating Expenses (or any group of such expenses) on an estimated basis in accordance with the provisions of Paragraph 3.2(a)(iii) above, Landlord shall furnish to Tenant within three months following the end of the applicable calendar or fiscal year, as the case may be, a statement setting forth (i) the amount of such expenses paid or incurred during the just ended calendar or fiscal year, as appropriate, and (ii) the amount that Tenant has paid to Landlord for credit against such expenses for such period. If Tenant shall have paid more than its obligation for such expenses for the stated period, Landlord shall, at its election, either (i) credit the amount of such overpayment toward the next ensuing payment or payments of Additional Rent that would otherwise be due or (ii) refund in cash to Tenant the amount of such overpayment. If such year-end statement shall show that Tenant did not pay its obligation for such expenses in full, then Tenant shall pay to Landlord the amount of such underpayment within ten days from Landlord’s billing of same to Tenant. The provisions of this Paragraph shall survive the expiration or sooner termination of this Lease.

3.4 Late Charge, And Interest On Rent In Default. Tenant acknowledges that the late payment by Tenant of any monthly installment of Base Monthly Rent or any Additional Rent will cause Landlord to incur certain costs and expenses not contemplated under this Lease, the exact amounts of which are extremely difficult or impractical to fix. Such costs and expenses will include without limitation, administration and collection costs and processing and accounting expenses. Therefor, if any installment of Base Monthly Rent is not received by Landlord from Tenant within five (5) calendar days after the same becomes due, at Landlord’s option, Tenant shall immediately pay to Landlord a late charge in an amount equal to the amount set forth in Article 1 as the “Late Charge Amount,” and if any Additional Rent is not received by Landlord within five (5) calendar days after the same becomes due, at Landlord’s option, Tenant shall immediately pay to Landlord a late charge in an amount equal to 5% of the Additional Rent not so paid. Landlord and Tenant agree that this late charge represents a reasonable estimate of such costs and expenses and is fair compensation to Landlord for the anticipated loss Landlord would suffer by reason of Tenant’s failure to make timely payment. In no event shall this provision for a late charge be deemed to grant to Tenant a grace period or extension of time within which to pay any rental installment or prevent Landlord from exercising any right or remedy available to Landlord upon Tenant’s failure to pay each rental installment due under this Lease when due, including the right to terminate this Lease. If any rent remains delinquent for a period in excess of five (5) calendar days, then, in addition to such late charge, Tenant shall pay to Landlord interest on any rent that is not so paid from said tenth day at the then maximum rate of interest not prohibited or made usurious by Law until paid.

3.5 Payment Of Rent. Except as specifically provided otherwise in this Lease, all rent shall be paid in lawful money of the United States, without any abatement, reduction or offset for any reason whatsoever, to Landlord at such address as Landlord may designate from time to time. Tenant’s obligation to pay Base Monthly Rent and all Additional Rent shall be appropriately prorated at the commencement and expiration of the Lease Term. The failure by Tenant to pay any Additional Rent as required pursuant to this Lease when due shall be treated the same as a

failure by Tenant to pay Base Monthly Rent when due, and Landlord shall have the same rights and remedies against Tenant as Landlord would have had Tenant failed to pay the Base Monthly Rent when due.

3.6 Prepaid Rent. Tenant shall, upon execution of this Lease, pay to Landlord the amount set forth in Article 1 as “First Month’s Prepaid Rent” as prepayment of rent for credit against the first and second payment of Base Monthly Rent due hereunder.

3.7 Security Deposit. Tenant shall deposit within five (5) business days after Tenant’s execution of this Lease, with Landlord the amount set forth in Article 1 as the “Security Deposit” as security for the performance by Tenant of the terms of this Lease to be performed by Tenant, and not as prepayment of rent. Tenant hereby grants to Landlord a security interest in the Security Deposit, including but not limited to replenishments thereof. Landlord may apply such portion or portions of the Security Deposit as are reasonably necessary for the following purposes: (i) to remedy any default by Tenant in the payment of Base Monthly Rent or Additional Rent or a late charge or interest on defaulted rent, or any other monetary payment obligation of Tenant under this Lease; (ii) to repair damage to the Leased Premises, the Building or the Outside Areas caused or permitted to occur by Tenant; (iii) to clean and restore and repair the Leased Premises, the Building or the Outside Areas following their surrender to Landlord if not surrendered in the condition required pursuant to the provisions of Article 2, and (iv) to remedy any other default of Tenant to the extent permitted by Law including, without limitation, paying in full on Tenant’s behalf any sums claimed by materialmen or contractors of Tenant to be owing to them by Tenant for work done or improvements made at Tenant’s request to the Leased Premises. In this regard, Tenant hereby waives any restriction on the uses to which the Security Deposit may be applied as contained in Section 1950.7(c) of the California Civil Code and/or any successor statute. In the event the Security Deposit or any portion thereof is so used, Tenant shall pay to Landlord, promptly upon demand, an amount in cash sufficient to restore the Security Deposit to the full original sum. If Tenant fails to promptly restore the Security Deposit and if Tenant shall have paid to Landlord any sums as “Last Month’s Prepaid Rent,” Landlord may, in addition to any other remedy Landlord may have under this Lease, reduce the amount of Tenant’s Last Month’s Prepaid Rent by transferring all or portions of such Last Month’s Prepaid Rent to Tenant’s Security Deposit until such Security Deposit is restored to the amount set forth in Article 1. Landlord shall not be deemed a trustee of the Security Deposit. Landlord may use the Security Deposit in Landlord’s ordinary business and shall not be required to segregate it from Landlord’s general accounts. Tenant shall not be entitled to any interest on the Security Deposit. If Landlord transfers the Building or the Property during the Lease Term, Landlord shall transfer or pay the Security Deposit to any subsequent owner in conformity with the provisions of Section 1950.7 of the California Civil Code and/or any successor statute, in which event the transferring landlord shall be released from all liability for the return of the Security Deposit. Tenant specifically grants to Landlord (and Tenant hereby waives the provisions of California Civil Code Section 1950.7 to the contrary) a period of ninety days following a surrender of the Leased Premises by Tenant to Landlord within which to inspect the Leased Premises, make required restorations and repairs, receive and verify workmen’s ▇▇▇▇▇▇▇▇ therefor, and prepare a final accounting with respect to the Security Deposit. In no event shall the Security Deposit or any portion thereof, be considered prepaid rent. Notwithstanding the foregoing, Tenant may deliver to Landlord a clean, unconditional, irrevocable, transferable letter of credit in lieu of cash for the Security Deposit (the “Letter of Credit”) in form and issued by a financial institution (“Issuer”) satisfactory to Landlord in its sole discretion, substantially in the form attached as Exhibit C. The Letter of Credit shall permit partial draws, and provide that draws thereunder will be honored upon receipt by Issuer of a written statement signed by Landlord or its authorized agent stating that Landlord is entitled to draw down on the Letter of Credit pursuant to the terms of the Lease. The Letter of Credit shall have an expiration period of one (1) year but shall automatically renew by its terms unless affirmatively cancelled by either Issuer or Tenant, in which case Issuer must provide Landlord 30 days’ prior written notice of such expiration or cancellation. Any amount drawn under the Letter of Credit shall be held or used by Landlord in accordance with this Paragraph 3.7. If the amount of the Letter of Credit is reduced in accordance with the terms of this Lease, Tenant shall have the right to replace the existing Letter of Credit with another Letter of Credit at the reduced amount. If the Tenant fails to renew or replace the Letter of Credit as required under this Lease at least thirty (30) days before its stated expiration date, Landlord may draw upon the entire amount of the Letter of Credit.

(d) At any time prior to expiration of the Lease term, subject to reasonable prior notice (not less than forty-eight (48) hours) and Tenant’s reasonable security requirements and provided such activities do not unreasonably interfere with the conduct of Tenant’s business at the Leased Premises, Landlord shall have the right to enter in and upon the Property, Building and Leased Premises in order to conduct appropriate tests of water and soil to determine whether levels of any Hazardous Materials in excess of legally permissible levels has occurred as a result of Tenant’s use thereof. Landlord shall furnish copies of all such test results and reports to Tenant and, at Tenant’s option and cost, shall permit split sampling for testing and analysis by Tenant. Such testing shall be at Tenant’s expense if Landlord has a reasonable basis for suspecting and confirms the presence of Hazardous Materials in the soil or surface or ground water in, on, under, or about the Property, the Building or the Leased Premises, which has been caused by or resulted from the activities of Tenant, its agents, contractors, or invitees.

(e) Landlord may voluntarily cooperate in a reasonable manner with the efforts of all governmental agencies in reducing actual or potential environmental damage.

Upon delivery to Tenant of a copy of such rules and regulations or any amendments or additions thereto, Tenant shall comply with such rules and regulations. A violation by Tenant of any of such rules and regulations shall constitute a default by Tenant under this Lease, subject to any applicable cure period.

Landlord shall not be responsible or liable to Tenant for the violation of such rules and regulations by any other tenant of the Property.

Landlord reserves the right from time to time to grant, without the consent or joinder of Tenant, such easements, rights of way and dedications that Landlord deems necessary, and to cause the recordation of parcel maps and restrictions, so long as such easements, rights of way and dedications do not unreasonably interfere with the use of the Leased Premises by Tenant.

ALTERATIONS AND IMPROVEMENTS

6.1 By Tenant. Tenant shall not make any alterations to or modifications of the Leased Premises or construct any improvements within the Leased Premises until Landlord shall have first approved, in writing, the plans and specifications therefor, which approval shall not be unreasonably withheld or delayed. Landlord’s approval shall be deemed given if not denied by Landlord in a written notice to Tenant delivered within fifteen (15) days following receipt of Tenant’s written request. Tenant’s written request shall also contain a request for Landlord to elect whether or not it will require Tenant to remove the subject alterations, modifications or improvements at the expiration or earlier termination of this Lease. If such additional request is not included, Landlord may make such election at the expiration or earlier termination of this Lease (and for purposes of Tenant’s removal obligations set forth in Paragraph 2.6 above, Landlord shall be deemed to have made the election at the time the alterations, modifications or improvements were completed). All such modifications, alterations or improvements, once so approved, shall be made, constructed or installed by Tenant at Tenant’s expense (including all permit fees and governmental charges related thereto), using a licensed contractor first approved by Landlord, in substantial compliance with the Landlord-approved plans and specifications therefor. All work undertaken by Tenant shall be done in accordance with all Laws and in a good and workmanlike manner using new materials of good quality. Tenant shall not commence the making of any such modifications or alterations or the construction of any such improvements until (i) all required governmental approvals and permits shall have been obtained, (ii) all requirements regarding insurance imposed by this Lease have been satisfied, (iii) Tenant shall have given Landlord at least five (5) business days prior written notice of its intention to commence such work so that Landlord may post and file notices of non-responsibility, and (iv) if requested by Landlord, Tenant shall have obtained contingent liability and broad form builder’s risk insurance in an amount satisfactory to Landlord in its reasonable discretion to cover any perils relating to the proposed work not covered by insurance carried by Tenant pursuant to Article 9. In no event shall Tenant make any modification, alterations or improvements whatsoever to the Outside Areas or the exterior or structural components of the Building including, without limitation, any cuts or penetrations in the floor, roof or exterior walls of the Leased Premises. As used in this Article, the term “modifications, alterations and/or improvements” shall include, without limitation, the installation of additional electrical outlets, overhead lighting fixtures, drains, sinks, partitions, doorways, or the like.

Any such modifications, alterations or improvements, once completed, shall not be altered or removed from the Leased Premises during the Lease Term without Landlord’s written approval first obtained in accordance with the provisions of Paragraph 6.1 above. At the expiration or sooner termination of this Lease, all such modifications, alterations and improvements other than Tenant’s inventory, equipment, movable furniture, furnishings and partitions, wall decorations and trade fixtures, shall automatically become the property of Landlord and shall be surrendered to Landlord as part of the Leased Premises as required pursuant to Article 2, unless Landlord shall require Tenant to remove any of such modifications, alterations or improvements in accordance with the provisions of Article 2, in which case Tenant shall so remove same. Landlord shall have no obligations to reimburse Tenant for all or any portion of the cost or value of any such modifications, alterations or improvements so surrendered to Landlord. All modifications, alterations or improvements which are installed or constructed on or attached to the Leased Premises by Landlord and/or at Landlord’s expense shall be deemed real property and a part of the Leased Premises and shall be property of Landlord. All lighting, plumbing, electrical, heating, ventilating and air conditioning fixtures, partitioning, window coverings, wall coverings and floor coverings installed by Tenant shall be deemed improvements to the Leased Premises and not trade fixtures of Tenant.

6.3 Alterations Required By Law. Tenant shall make all modifications, alterations and improvements to the Leased Premises, at its sole cost, that are required by any Law because of (i) Tenant’s use or occupancy of the Leased Premises, the Building, the Outside Areas or the Property, (ii) Tenant’s application for any permit or governmental approval, or (iii) Tenant’s making of any modifications, alterations or improvements to or within the Leased Premises. If Landlord shall, at any time during the Lease Term, be required by any governmental authority to make any modifications, alterations or improvements to the Building or the Property, the cost incurred by Landlord in making such modifications, alterations or improvements, including interest at a rate equal to the greater of (a) 12%, or (b) the sum of that rate quoted by ▇▇▇▇▇ Fargo Bank, N.T. & S.A. from time to time as its prime rate, plus two percent (2%) (“▇▇▇▇▇ Prime Plus Two”) (but in no event more than the maximum rate of interest not

10.

prohibited or made usurious), shall be amortized by Landlord over the useful life of such modifications, alterations or improvements, as determined in accordance with generally accepted accounting principles, and the monthly amortized cost of such modifications, alterations and improvements as so amortized shall be considered a Property Maintenance Cost.

6.4 Liens. Tenant shall keep the Property and every part thereof free from any lien, and shall pay when due all bills arising out of any work performed, materials furnished, or obligations incurred by Tenant, its agents, employees or contractors relating to the Property. If any such claim of lien is recorded against Tenant’s interest in this Lease, the Property or any part thereof, Tenant shall bond against, discharge or otherwise cause such lien to be entirely released within ten days after Tenant becomes aware that the same has been recorded (whether by notice from the contractor or otherwise). Tenant’s failure to do so shall be conclusively deemed a material default under the terms of this Lease.

7.1 By Tenant. Tenant shall not sublet the Leased Premises or any portion thereof or assign its interest in this Lease, whether voluntarily or by operation of Law, without Landlord’s prior written consent which shall not be unreasonably withheld or delayed. Any attempted subletting or assignment without Landlord’s prior written consent, at Landlord’s election, shall constitute a default by Tenant under the terms of this Lease. The acceptance of rent by Landlord from any person or entity other than Tenant, or the acceptance of rent by Landlord from Tenant with knowledge of a violation of the provisions of this paragraph, shall not be deemed to be a waiver by Landlord of any provision of this Article or this Lease or to be a consent to any subletting by Tenant or any assignment of Tenant’s interest in this Lease.

(b) in Landlord’s reasonable judgment, the use of the Leased Premises by the proposed assignee or sublessee would involve occupancy by other than for a Permitted Use, would entail any alterations which would substantially lessen the value of the leasehold improvements in the Leased Premises, or would require increased services by Landlord;

(c) with respect an assignment, in Landlord’s reasonable judgment, the financial worth of the proposed assignee is less than that of Tenant or does not meet the credit standards applied by Landlord;

(d) the proposed assignee or sublessee has been in material default under a lease within the last two (2) years, has been in litigation within the last two (2) years with a previous landlord, or in the two (2) years prior to the assignment or sublease has filed for bankruptcy protection, has been the subject of an involuntary bankruptcy, or has been adjudged insolvent;

(e) Landlord has experienced a previous default by or is in litigation with the proposed assignee or sublessee;

(f) in Landlord’s reasonable judgment, the Leased Premises, or the relevant part thereof, will be used in a manner that will violate any negative covenant as to use contained in this Lease;

(i) the proposed assignment or sublease fails to include all of the terms and provisions required to be included therein pursuant to this Article 7;

(j) Tenant is in default of any obligation of Tenant under this Lease, or Tenant has defaulted under this Lease on three or more occasions during the 12 months preceding the date that Tenant shall request consent; or

(k) in the case of a subletting of less than the entire Leased Premises, if the subletting would result in the division of the Leased Premises into more than two subparcels or would require improvements to be made outside of the Leased Premises.

7.2 Merger, Reorganization, or Sale of Assets. Any dissolution, merger, consolidation or other reorganization of Tenant, or the sale or other transfer in the aggregate over the Lease Term of a controlling percentage of the capital stock of Tenant (except in the case of an initial public offering or sale of Tenant’s stock through a national public exchange), or the sale or transfer of all or a substantial portion of the assets of Tenant, shall be deemed a voluntary assignment of Tenant’s interest in this Lease. The phrase “controlling percentage” means the ownership of and the right to vote stock possessing more than fifty percent of the total combined voting power of all classes of Tenant’s capital stock issued, outstanding and entitled to vote for the election of directors. If Tenant is a partnership, a withdrawal or change, voluntary, involuntary or by operation of Law, of any general partner, or the dissolution of the partnership, shall be deemed a voluntary assignment of Tenant’s interest in this Lease. Upon Landlord’s request from time to time, Tenant shall promptly provide Landlord with a statement certified by the Tenant’s chief operating officer, which shall provide the following information: (a) the names of all of Tenant’s shareholders and their

11.

ownership interests at the time thereof, provided Tenant’s shares are not publicly traded; (b) the state in which Tenant is incorporated; (c) the location of Tenant’s principal place of business; (d) information regarding a material change in the corporate structure of Tenant, including, without limitation, a merger or consolidation; and (e) any other information regarding Tenant’s ownership that Landlord reasonably requests. Notwithstanding the foregoing, Tenant may, without Landlord’s prior written consent, sublet all or a portion of the Leased Premises or assign this Lease to (each a “Permitted Transferee”) (i) a subsidiary, affiliate, division, corporation or joint venture controlling, controlled by or under common control with Tenant, (ii) a successor entity resulting from a merger, consolidation, or nonbankruptcy reorganization by Tenant, or (iii) a purchaser of substantially all of Tenant’s assets located in the Leased Premises, provided that the successor entity, assignee or subtenant has a net worth equal to or greater than that of Tenant as of the date of the transfer and provided that Tenant remains fully and primarily liable under this Lease (unless due to a merger, consolidation, or nonbankruptcy reorganization Tenant ceases to exist as a legal entity).

7.3 Landlord’s Election. If Tenant shall desire to assign its interest under the Lease or to sublet the Leased Premises, Tenant must first notify Landlord, in writing, of its intent to so assign or sublet, at least thirty (30) days in advance of the date it intends to so assign its interest in this Lease or sublet the Leased Premises but not sooner than one hundred eighty days in advance of such date, specifying in detail the terms of such proposed assignment or subletting, including the name of the proposed assignee or sublessee, the property assignee’s or sublessee’s intended use of the Leased Premises, current financial statements (including a balance sheet, income statement and statement of cash flow, all prepared in accordance with generally accepted accounting principles) of such proposed assignee or sublessee, the form of documents to be used in effectuating such assignment or subletting and such other information as Landlord may reasonably request. Landlord shall have a period of fifteen (15) days following receipt of such notice and the required information within which to do one of the following: (i) consent to such requested assignment or subletting subject to Tenant’s compliance with the conditions set forth in Paragraph 7.4 below, or (ii) refuse to so consent to such requested assignment or subletting, provided that such consent shall not be unreasonably refused. During such ten (10) business day period, Tenant covenants and agrees to supply to Landlord, upon request, all necessary or relevant information which Landlord may reasonably request respecting such proposed assignment or subletting and/or the proposed assignee or sublessee. Tenant’s written request may also contain a request in ALL CAPITALS BOLD FACE TYPE for Landlord to respond within fifteen (15) days. If Tenant includes such a request, and Landlord fails to respond within such fifteen (15) day period, the proposed assignment or subletting shall be deemed approved.

7.4 Conditions To Landlord’s Consent. If Landlord elects to consent, or shall have been ordered to so consent by a court of competent jurisdiction, to such requested assignment or subletting, such consent shall be expressly conditioned upon the occurrence of each of the conditions below set forth, and any purported assignment or subletting made or ordered prior to the full and complete satisfaction of each of the following conditions shall be void and, at the election of Landlord, which election may be exercised at any time following such a purported assignment or subletting but prior to the satisfaction of each of the stated conditions, shall constitute a material default by Tenant under this Lease until cured by satisfying in full each such condition by the assignee or sublessee. The conditions are as follows:

(a) Landlord having approved in form and substance the assignment or sublease agreement and any ancillary documents, which approval shall not be unreasonably withheld by Landlord if the requirements of this Article 7 are otherwise complied with.

(b) Each such sublessee or assignee having agreed, in writing satisfactory to Landlord and its counsel and for the benefit of Landlord, to assume, to be bound by, and to perform the obligations of this Lease to be performed by Tenant which relate to space being subleased.

(c) Tenant having fully and completely performed all of its obligations under the terms of this Lease through and including the date of such assignment or subletting.

(d) Tenant having reimbursed to Landlord all reasonable costs and reasonable attorneys’ fees incurred by Landlord in conjunction with the processing and documentation of any such requested subletting or assignment.

(e) Tenant having delivered to Landlord a complete and fully-executed copy of such sublease agreement or assignment agreement (as applicable) and all related agreements.

(f) Tenant having paid, or having agreed in writing to pay as to future payments, to Landlord seventy five percent (75%) of all assignment consideration or excess rentals to be paid to Tenant or to any other on Tenant’s behalf or for Tenant’s benefit for such assignment or subletting as follows:

(i) If Tenant assigns its interest under this Lease and if all or a portion of the consideration for such assignment is to be paid by the assignee at the time of the assignment, that Tenant shall have paid to Landlord and Landlord shall have received an amount equal to seventy five percent (75%) of the assignment consideration so paid or to be paid (whichever is the greater) at the time of the assignment by the assignee; or

(ii) If Tenant assigns its interest under this Lease and if Tenant is to receive all or a portion of the consideration for such assignment in future installments, that Tenant and Tenant’s assignee shall have entered into a written agreement with and for the benefit of Landlord satisfactory to Landlord and its counsel whereby Tenant and Tenant’s assignee jointly agree to pay to Landlord an amount equal to seventy five percent (75%) of all such future assignment consideration installments to be paid by such assignee as and when such assignment consideration is so paid.

12.

(iii) If Tenant subleases the Leased Premises, that Tenant and Tenant’s sublessee shall have entered into a written agreement with and for the benefit of Landlord satisfactory to Landlord and its counsel whereby Tenant and Tenant’s sublessee jointly agree to pay to Landlord seventy five percent (75%) of all excess rentals to be paid by such sublessee as and when such excess rentals are so paid.

7.5 Assignment Consideration And Excess Rentals Defined. For purposes of this Article, including any amendment to this Article by way of addendum or other writing, the term “assignment consideration” shall mean all consideration to be paid by the assignee to Tenant or to any other party on Tenant’s behalf or for Tenant’s benefit as consideration for such assignment, after deduction for reasonable leasing commissions and reasonable legal fees incurred by Tenant in connection with such assignment, but without deduction for any other costs or expenses (including, without limitation, capital improvements, building upgrades, permit fees, attorneys’ fees, and other consultants’ fees), and the term “excess rentals” shall mean all consideration to be paid by the sublessee to Tenant or to any other party on Tenant’s behalf or for Tenant’s benefit for the sublease of the Leased Premises in excess of the rent due to Landlord under the terms of this Lease for the same period, after deduction for reasonable leasing commissions and reasonable legal fees incurred by Tenant in connection with such sublease, but without deduction for any other costs or expenses (including, without limitation, capital improvements, building upgrades, permit fees, attorneys’ fees, and other consultants’ fees). Tenant agrees that the portion of any assignment consideration and/or excess rentals arising from any assignment or subletting by Tenant which is to be paid to Landlord pursuant to this Article now is and shall then be the property of Landlord and not the property of Tenant.

7.6 Payments. All payments required by this Article to be made to Landlord shall be made in cash in full as and when they become due. At the time Tenant, Tenant’s assignee or sublessee makes each such payment to Landlord, Tenant or Tenant’s assignee or sublessee, as the case may be, shall deliver to Landlord an itemized statement in reasonable detail showing the method by which the amount due Landlord was calculated and certified by the party making such payment as true and correct.

7.7 Good Faith. The rights granted to Tenant by this Article are granted in consideration of Tenant’s express covenant that all pertinent allocations which are made by Tenant between the rental value of the Leased Premises and the value of any of Tenant’s personal property which may be conveyed or leased generally concurrently with and which may reasonably be considered a part of the same transaction as the permitted assignment or subletting shall be made fairly, honestly and in good faith. If Tenant shall breach this covenant, Landlord may immediately declare Tenant to be in default under the terms of this Lease and terminate this Lease and/or exercise any other rights and remedies Landlord would have under the terms of this Lease in the case of a material default by Tenant under this Lease.

7.8 Effect Of Landlord’s Consent. No subletting or assignment, even with the consent of Landlord, shall relieve Tenant of its personal and primary obligation to pay rent and to perform all of the other obligations to be performed by Tenant hereunder. Consent by Landlord to one or more assignments of Tenant’s interest in this Lease or to one or more sublettings of the Leased Premises shall not be deemed to be a consent to any subsequent assignment or subletting. If Landlord shall have been ordered by a court of competent jurisdiction to consent to a requested assignment or subletting, or such an assignment or subletting shall have been ordered by a court of competent jurisdiction over the objection of Landlord, such assignment or subletting shall not be binding between the assignee (or sublessee) and Landlord until such time as all conditions set forth in Paragraph 7.4 above have been fully satisfied (to the extent not then satisfied) by the assignee or sublessee, including, without limitation, the payment to Landlord of all agreed assignment considerations and/or excess rentals then due Landlord.

ARTICLE 8

LIMITATION ON LANDLORD’S LIABILITY AND INDEMNITY

8.1 Limitation On Landlord’s Liability And Release. Landlord shall not be liable to Tenant for, and Tenant hereby releases Landlord and its partners, principals, members, officers, agents, employees, lenders, attorneys, and consultants from, any and all liability, whether in contract, tort or on any other basis, for any injury to or any damage sustained by Tenant, Tenant’s agents, employees, contractors or invitees, any damage to Tenant’s property, or any loss to Tenant’s business, loss of Tenant’s profits or other financial loss of Tenant resulting from or attributable to the condition of, the management of, the repair or maintenance of, the protection of, the supply of services or utilities to, the damage in or destruction of the Leased Premises, the Building, the Property or the Outside Areas, including without limitation (i) the failure, interruption, rationing or other curtailment or cessation in the supply of electricity, water, gas or other utility service to the Property, the Building or the Leased Premises; (ii) the vandalism or forcible entry into the Building or the Leased Premises; (iii) the penetration of water into or onto any portion of the Leased Premises; (iv) the failure to provide security and/or adequate lighting in or about the Property, the Building or the Leased Premises, (v) the existence of any design or construction defects within the Property, the Building or the Leased Premises; (vi) the failure of any mechanical systems to function properly (such as the HVAC systems); (vii) the blockage of access to any portion of the Property, the Building or the Leased Premises, except that Tenant does not so release Landlord from such liability to the extent such damage was proximately caused by Landlord’s active negligence, willful misconduct, or Landlord’s failure to perform an obligation expressly undertaken pursuant to this Lease after a reasonable period of time shall have lapsed following receipt of written notice from Tenant to so perform such obligation. In this regard, Tenant acknowledges that it is fully apprised of the provisions of Law relating to releases, and particularly to those provisions contained in 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.

Notwithstanding such statutory provision, and for the purpose of implementing a full and complete release and discharge, Tenant hereby (i) waives the benefit of such statutory provision and (ii) acknowledges that, subject to the exceptions specifically set forth herein, the release and discharge set forth in this paragraph is a full and complete settlement and release and discharge of all claims and is intended to include in its effect, without limitation, all claims which Tenant, as of the date hereof, does not know of or suspect to exist in its favor.

8.2 Tenant’s Indemnification Of Landlord. Tenant shall defend with competent counsel reasonably satisfactory to Landlord any claims made or legal actions filed or threatened against Landlord with respect to the violation of any Law by Tenant, its agents, employees, invitees or contractors, or the death, bodily injury, personal injury, property damage, or interference with contractual or property rights suffered by any third party occurring within the Leased Premises or resulting from Tenant’s use or occupancy of the Leased Premises, the Building or the Outside Areas, or resulting from Tenant’s activities in or about the Leased Premises, the Building, the Outside Areas or the Property, and Tenant shall indemnify and hold Landlord, Landlord’s partners, principals, members, employees, agents and contractors harmless from any loss liability, penalties, or expense whatsoever (including any loss attributable to vacant space which otherwise would have been leased, but for such activities) resulting therefrom, except to the extent proximately caused by the active negligence or willful misconduct of Landlord. This indemnity agreement shall survive the expiration or sooner termination of this Lease.

ARTICLE 9

(viii) With respect to making of any alterations or modifications or the construction of improvements or the like undertaken by Tenant, course of construction, commercial general liability, automobile liability and workers’ compensation (to be carried by Tenant’s contractor), in an amount and with coverage reasonably satisfactory to Landlord.

(b) Each policy of liability insurance required to be carried by Tenant pursuant to this paragraph or actually carried by Tenant with respect to the Leased Premises or the Property: (i) shall, except with respect to insurance required by subparagraph (a)(vii) above, name Landlord, and such others as are designated by Landlord, as additional insureds; (ii) shall be primary insurance providing that the insurer shall be liable for the full amount of the loss, up to and including the total amount of liability set forth in the declaration of coverage, without the right of contribution from or prior payment by any other insurance coverage of Landlord; (iii) shall be in a form satisfactory to Landlord; (iv) shall be carried with companies reasonably acceptable to Landlord with Best’s ratings of at least A and XI; (v) shall provide that such policy shall not be subject to cancellation, lapse or change except after at least thirty (30) days prior written notice to Landlord, and (vi) shall contain a so-called “severability” or “cross liability” endorsement.

(c) Prior to the time Tenant or any of its contractors enters the Leased Premises, Tenant shall deliver to Landlord, with respect to each policy of insurance required to be carried by Tenant pursuant to this Article, a copy

14.

of such policy (appropriately authenticated by the insurer as having been issued, premium paid) or a certificate of the insurer certifying in form satisfactory to Landlord that a policy has been issued, premium paid, providing the coverage required by this Paragraph and containing the provisions specified herein. With respect to each renewal or replacement of any such insurance, the requirements of this Paragraph must be complied with not less than thirty days prior to the expiration or cancellation of the policies being renewed or replaced. Landlord may, at any time and from time to time, inspect and/or copy any and all insurance policies required to be carried by Tenant pursuant to this Article. If Landlord’s Lender, insurance broker, advisor or counsel reasonably determines at any time that the amount of coverage set forth in Paragraph 9.1(a) for any policy of insurance Tenant is required to carry pursuant to this Article is not adequate, then Tenant shall increase the amount of coverage for such insurance to such greater amount as Landlord’s Lender, insurance broker, advisor or counsel reasonably deems adequate.

9.2 Landlord’s Insurance. With respect to insurance maintained by Landlord:

(a) Landlord shall maintain, as the minimum coverage required of it by this Lease, fire and property damage insurance in so-called special form coverage insuring Landlord (and such others as Landlord may designate) against loss from physical damage to the Building with coverage of not less than one hundred percent (100%) of the full actual replacement cost thereof and against loss of rents for a period of not less than six months.

Landlord shall not be required to cause such insurance to cover any of Tenant’s personal property, inventory, and trade fixtures, or any modifications, alterations or improvements made or constructed by Tenant to or within the Leased Premises. Landlord shall use commercially reasonable efforts to obtain such insurance at competitive rates.

(b) Landlord shall maintain commercial general liability insurance insuring Landlord (and such others as are designated by Landlord) against liability for personal injury, bodily injury, death, and damage to property occurring in, on or about, or resulting from the use or occupancy of the Property, or any portion thereof, with combined single limit coverage of at least Three Million Dollars ($3,000,000). Landlord may carry such greater coverage as Landlord or Landlord’s Lender, insurance broker, advisor or counsel may from time to time determine is reasonably necessary for the adequate protection of Landlord and the Property.

(c) Landlord may maintain any other insurance which in the reasonable opinion of its insurance broker, advisor or legal counsel is prudent to carry under the given circumstances, provided such insurance is commonly carried by owners of property similarly situated and operating under similar circumstances.

9.3 Mutual Waiver Of Subrogation. Landlord hereby releases Tenant, and Tenant hereby releases Landlord and its respective directors, shareholders, partners, principals, members, officers, agents, employees and servants, from any and all liability for loss, damage or injury to the property of the other in or about the Leased Premises or the Property which is caused by or results from a peril or event or happening which is covered by insurance actually carried and in force at the time of the loss by the party sustaining such loss; provided, however, that such waiver shall be effective only to the extent permitted by the insurance covering such loss and to the extent such insurance is not prejudiced thereby.

ARTICLE 10

DAMAGE TO LEASED PREMISES

10.1 Landlord’s Duty To Restore. If the Leased Premises, the Building or the Outside Area are damaged by any peril after the Effective Date of this Lease, Landlord shall restore the same, as and when required by this paragraph, unless this Lease is terminated by Landlord pursuant to Paragraph 10.3 or by Tenant pursuant to Paragraph 10.4. If this Lease is not so terminated, then upon the issuance of all necessary governmental permits, Landlord shall commence and diligently prosecute to completion the restoration of the Leased Premises, the Building or the Outside Area, as the case may be, to the extent then allowed by law, to substantially the same condition in which it existed as of the Lease Commencement Date. Landlord’s obligation to restore shall be limited to the improvements constructed by Landlord. Landlord shall have no obligation to restore any alterations, modifications or improvements made by Tenant to the Leased Premises or any of Tenant’s personal property, inventory or trade fixtures. Upon completion of the restoration by Landlord, Tenant shall forthwith replace or fully repair Tenant’s personal property, inventory, trade fixtures and other improvements constructed by Tenant to like or similar conditions as existed at the time immediately prior to such damage or destruction, to the extent covered by insurance proceeds.

10.2 Insurance Proceeds. All insurance proceeds available from the fire and property damage insurance carried by Landlord shall be paid to and become the property of Landlord. If this Lease is terminated pursuant to either Paragraph 10.3 or 10.4, all insurance proceeds available from insurance carried by Tenant which cover loss of property that is Landlord’s property or would become Landlord’s property on termination of this Lease shall be paid to and become the property of Landlord, and the remainder of such proceeds shall be paid to and become the property of Tenant. If this Lease is not terminated pursuant to either Paragraph 10.3 or 10.4, all insurance proceeds available from insurance carried by Tenant which cover loss to property that is Landlord’s property shall be paid to and become the property of Landlord, and all proceeds available from such insurance which cover loss to property which would only become the property of Landlord upon the termination of this Lease shall be paid to and remain the property of Tenant. The determination of Landlord’s property and Tenant’s property shall be made pursuant to Paragraph 6.2.

15.

10.3 Landlord’s Right To Terminate. Landlord shall have the option to terminate this Lease in the event any of the following occurs, which option may be exercised only by delivery to Tenant of a written notice of election to terminate within thirty days after the date of such damage or destruction:

(a) The Building is damaged by any peril covered by valid and collectible insurance actually carried by Landlord and in force at the time of such damage or destruction (an “insured peril”) to such an extent that the estimated cost to restore the Building exceeds the lesser of (i) the insurance proceeds available from insurance actually carried by Landlord, or (ii) fifty percent of the then actual replacement cost thereof;

(b) The Building is damaged by an uninsured peril, which peril Landlord was not required to insure against pursuant to the provisions of Article 9 of this Lease.

(c) The Building is damaged by any peril and, because of the laws then in force, the Building (i) cannot be restored at reasonable cost or (ii) if restored, cannot be used for the same use being made thereof before such damage.

10.4 Tenant’s Right To Terminate. If the Leased Premises, the Building or the Outside Area are damaged by any peril and Landlord does not elect to terminate this Lease or is not entitled to terminate this Lease pursuant to this Article, then as soon as reasonably practicable, Landlord shall furnish Tenant with the written opinion of Landlord’s architect or construction consultant as to when the restoration work required of Landlord may be complete. Tenant shall have the option to terminate this Lease in the event any of the following occurs, which option may be exercised only by delivery to Landlord of a written notice of election to terminate within seven days after Tenant receives from Landlord the estimate of the time needed to complete such restoration:

(a) If the time estimated to substantially complete the restoration exceeds nine (9) months from and after the date of the damage; or

(b) If the damage occurred within twelve months of the last day of the Lease Term and the time estimated to substantially complete the restoration exceeds one hundred fifty (150) days from the date of the damage.

10.5 Tenant’s Waiver. Landlord and Tenant agree that the provisions of Paragraph 10.4 above, captioned “Tenant’s Right To Terminate”, are intended to supersede and replace the provisions contained in California Civil Code, Section 1932, Subdivision 2, and California Civil Code, Section 1934, and accordingly, Tenant hereby waives the provisions of such Civil Code Sections and the provisions of any successor Civil Code Sections or similar laws hereinafter enacted.

10.6 Abatement Of Rent. In the event of damage to the Leased Premises which does not result in the termination of this Lease, the Base Monthly Rent (and any Additional Rent) shall be temporarily abated during the period of restoration in proportion in the degree to which Tenant’s use of the Leased Premises is impaired by such damage.

ARTICLE 11

CONDEMNATION

11.1 Tenant’s Right To Terminate. Except as otherwise provided in Paragraph 11.4 below regarding temporary takings, Tenant shall have the option to terminate this Lease if, as a result of any taking, (i) all of the Leased Premises is taken, or (ii) twenty-five percent (25%) or more of the Leased Premises is taken and the part of the Leased Premises that remains cannot, within a reasonable period of time, be made reasonably suitable for the continued operation of Tenant’s business. Tenant must exercise such option within a reasonable period of time, to be effective on the later to occur of (i) the date that possession of that portion of the Leased Premises that is condemned is taken by the condemnor or (ii) the date Tenant vacated the Leased Premises.

11.2 Landlord’s Right To Terminate. Except as otherwise provided in Paragraph 11.4 below regarding temporary takings, Landlord shall have the option to terminate this Lease if, as a result of any taking, (i) all of the Leased Premises is taken, (ii) twenty-five percent (25%) or more of the Leased Premises is taken and the part of the Leased Premises that remains cannot, within a reasonable period of time, be made reasonably suitable for the continued operation of Tenant’s business, or (iii) because of the laws then in force, the Leased Premises may not be used for the same use being made before such taking, whether or not restored as required by Paragraph 11.3 below. Any such option to terminate by Landlord must be exercised within a reasonable period of time, to be effective as of the date possession is taken by the condemnor.

11.3 Restoration. If any part of the Leased Premises or the Building is taken and this Lease is not terminated, then Landlord shall, to the extent not prohibited by laws then in force, repair any damage occasioned thereby to the remainder thereof to a condition reasonably suitable for Tenant’s continued operations and otherwise, to the extent practicable, in the manner and to the extent provided in Paragraph 10.1.

11.4 Temporary Taking. If a portion of the Leased Premises is temporarily taken for a period of one year or less and such period does not extend beyond the Lease Expiration Date, this Lease shall remain in effect. If any portion of the Leased Premises is temporarily taken for a period which exceeds one year or which extends beyond the Lease Expiration Date, then the rights of Landlord and Tenant shall be determined in accordance with Paragraphs 11.1 and 11.2 above.

11.5 Division Of Condemnation Award. Any award made for any taking of the Property, the Building, or the Leased Premises, or any portion thereof, shall belong to and be paid to Landlord, and Tenant hereby assigns to Landlord all of its right, title and interest in any such award; provided, however, that Tenant shall be entitled to

16.

receive any portion of the award that is made specifically (i) for the taking of personal property, inventory or trade fixtures belonging to Tenant, (ii) for the interruption of or loss to Tenant’s business or its moving costs, or (iii) for the value of any leasehold improvements installed and paid for by Tenant. The rights of Landlord and Tenant regarding any condemnation shall be determined as provided in this Article, and each party hereby waives the provisions of Section 1265.130 of the California Code of Civil Procedure, and the provisions of any similar law hereinafter enacted, allowing either party to petition the Supreme Court to terminate this Lease and/or otherwise allocate condemnation awards between Landlord and Tenant in the event of a taking of the Leased Premises.

11.6 Abatement Of Rent. In the event of a taking of the Leased Premises which does not result in a termination of this Lease (other than a temporary taking), then, as of the date possession is taken by the condemning authority, the Base Monthly Rent shall be reduced in the same proportion that the area of that part of the Leased Premises so taken (less any addition to the area of the Leased Premises by reason of any reconstruction) bears to the area of the Leased Premises immediately prior to such taking.

11.7 Taking Defined. The term “taking” or “taken” as used in this Article 11 shall mean any transfer or conveyance of all or any portion of the Property to a public or quasi-public agency or other entity having the power of eminent domain pursuant to or as a result of the exercise of such power by such an agency, including any inverse condemnation and/or any sale or transfer by Landlord of all or any portion of the Property to such an agency under threat of condemnation or the exercise of such power.

12.2 Landlord’s Remedies. In the event of any default by Tenant, and without limiting Landlord’s right to indemnification as provided in Article 8.2, Landlord shall have the following remedies, in addition to all other rights and remedies provided by law or otherwise provided in this Lease, to which Landlord may resort cumulatively, or in the alternative:

(a) Landlord may, at Landlord’s election, keep this Lease in effect and enforce, by an action at law or in equity, all of its rights and remedies under this Lease including, without limitation, (i) the right to recover the rent and other sums as they become due by appropriate legal action, (ii) the right to make payments required by Tenant, or perform Tenant’s obligations and be reimbursed by Tenant for the cost thereof with interest at the then maximum rate of interest not prohibited by law from the date the sum is paid by Landlord until Landlord is reimbursed by Tenant, and (iii) the remedies of injunctive relief and specific performance to prevent Tenant from violating the terms of this Lease and/or to compel Tenant to perform its obligations under this Lease, as the case may be.

(b) Landlord may, at Landlord’s election, terminate this Lease by giving Tenant written notice of termination, in which event this Lease shall terminate on the date set forth for termination in such notice, in which event Tenant shall immediately surrender the Leased Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Leased Premises and expel or remove Tenant and any other person who may be occupying the Leased Premises or any part thereof, without being liable for prosecution or any claim or damages therefor. Any termination under this subparagraph shall not relieve Tenant from its obligation to pay to Landlord all Base Monthly Rent and Additional Rent then or thereafter due, or any other sums due or thereafter accruing to Landlord, or from any claim against Tenant for damages previously accrued or then or thereafter accruing. In no event shall any one or more of the following actions by Landlord, in the absence of a written election by Landlord to terminate this Lease constitute a termination of this Lease:

(i) Appointment of a receiver or keeper in order to protect Landlord’s interest hereunder;

(ii) Consent to any subletting of the Leased Premises or assignment of this Lease by Tenant, whether pursuant to the provisions hereof or otherwise; or

(iii) Any action taken by Landlord or its partners, principals, members, officers, agents, employees, or servants, which is intended to mitigate the adverse effects of any breach of this Lease by Tenant, including, without limitation, any action taken to maintain and preserve the Leased Premises on any action taken to relet the Leased Premises or any portion thereof for the account of Tenant and in the name of Tenant.

(c) In the event Tenant breaches this Lease and abandons the Leased Premises, Landlord may terminate this Lease, but this Lease shall not terminate unless Landlord gives Tenant written notice of termination. If Landlord does not terminate this Lease by giving written notice of termination, Landlord may enforce all its rights and remedies under this Lease, including the right and remedies provided by California Civil Code Section 1951.4 (“lessor may continue lease in effect after lessee’s breach and abandonment and recover rent as it becomes due, if lessee has right to sublet or assign, subject only to reasonable limitations”), as in effect on the Effective Date of this Lease.

(d) In the event Landlord terminates this Lease, Landlord shall be entitled, at Landlord’s election, to the rights and remedies provided in California Civil Code Section 1951.2, as in effect on the Effective Date of this Lease. For purposes of computing damages pursuant to Section 1951.2, an interest rate equal to the maximum rate of interest then not prohibited by law shall be used where permitted. Such damages shall include, without limitation:

(i) The worth at the time of the award of the unpaid rent which had been earned at the time of termination;

(ii) The worth at the time of award of the amount by which the unpaid rent for the balance of the term after the time of award exceeds the amount of such rental loss that Tenant proves could be reasonably avoided, computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco, at the time of award plus one percent; and

(iii) Any other amount necessary to compensate Landlord for all detriment proximately caused by Tenant’s failure to perform Tenant’s obligations under this Lease, or which in the ordinary course of things would be likely to result therefrom, including without limitation, the following: (i) expenses for cleaning, repairing or restoring the Leased Premises, (ii) expenses for altering, remodeling or otherwise improving the Leased Premises for the purpose of reletting, including removal of existing leasehold improvements and/or installation of additional leasehold improvements (regardless of how the same is funded, including reduction of rent, a direct payment or allowance to a new tenant, or otherwise), (iii) broker’s fees allocable to the remainder of the term of this Lease, advertising costs and other expenses of reletting the Leased Premises; (iv) costs of carrying and maintaining the Leased Premises, such as taxes, insurance premiums, utility charges and security precautions, (v) expenses incurred in removing, disposing of and/or storing any of Tenant’s personal property, inventory or trade fixtures remaining therein; (vi) reasonable attorney’s fees, expert witness fees, court costs and other reasonable expenses incurred by Landlord (but not limited to taxable costs) in retaking possession of the Leased Premises, establishing damages hereunder, and releasing the Leased Premises; and (vii) any other expenses, costs or damages otherwise incurred or suffered as a result of Tenant’s default.

12.3 Landlord’s Default And Tenant’s Remedies. In the event Landlord fails to perform its obligations under this Lease, Landlord shall nevertheless not be in default under the terms of this Lease until such time as Tenant shall have first given Landlord written notice specifying the nature of such failure to perform its obligations, and then only after Landlord shall have had a reasonable time not to exceed thirty (30) days following its receipt of such notice within which to perform such obligations; provided that, if longer than thirty (30) days is reasonably required in order to perform such obligations, Landlord shall have such longer period. In the event of Landlord’s default as above set forth, then, and only then, Tenant may then proceed in equity or at law to compel Landlord to perform its

18.

obligations and/or to recover damages proximately caused by such failure to perform (except as and to the extent Tenant has waived its right to damages as provided in this Lease).

12.4 Limitation Of Tenant’s Recourse. Tenant’s sole recourse against Landlord shall be to Landlord’s interest in the Building and the Outside Areas, and any insurance proceeds actually received by Landlord for repair or restoration of the Building or Outside Areas. If Landlord is a corporation, trust, partnership, joint venture, limited liability company, unincorporated association, or other form of business entity, Tenant agrees that (i) the obligations of Landlord under this Lease shall not constitute personal obligations of the officers, directors, trustees, partners, joint venturers, members, owners, stockholders, or other principals of such business entity, and (ii) Tenant shall have recourse only to the interest of such corporation, trust, partnership, joint venture, limited liability company, unincorporated association, or other form of business entity in the Building and the Outside Areas for the satisfaction of such obligations and not against the assets of such officers, directors, trustees, partners, joint venturers, members, owners, stockholders or principals. Additionally, if Landlord is a partnership or limited liability company, then Tenant covenants and agrees:

(a) No partner or member of Landlord shall be sued or named as a party in any suit or action brought by Tenant with respect to any alleged breach of this Lease (except to the extent necessary to secure jurisdiction over the partnership and then only for that sole purpose);

(b) No service of process shall be made against any partner or member of Landlord except for the sole purpose of securing jurisdiction over the partnership; and

(c) No writ of execution will ever be levied against the assets of any partner or member of Landlord other than to the extent of his or her interest in the assets of the partnership or limited liability company constituting Landlord.

Tenant further agrees that each of the foregoing covenants and agreements shall be enforceable by Landlord and by any partner or member of Landlord and shall be applicable to any actual or alleged misrepresentation or nondisclosure made regarding this Lease or the Leased Premises or any actual or alleged failure, default or breach of any covenant or agreement either expressly or implicitly contained in this Lease or imposed by statute or at common law.

12.5 Tenant’s Waiver. Landlord and Tenant agree that the provisions of Paragraph 12.3 above are intended to supersede and replace the provisions of California Civil Code Sections 1932(1), 1941 and 1942, and accordingly, Tenant hereby waives the provisions of California Civil Code Sections 1932(1), 1941 and 1942 and/or any similar or successor law regarding Tenant’s right to terminate this Lease or to make repairs and deduct the expenses of such repairs from the rent due under this Lease.

ARTICLE 13

GENERAL PROVISIONS

13.1 Taxes On Tenant’s Property. Tenant shall pay before delinquency any and all taxes, assessments, license fees, use fees, permit fees and public charges of whatever nature or description levied, assessed or imposed against Tenant or Landlord by a governmental agency arising out of, caused by reason of or based upon Tenant’s estate in this Lease, Tenant’s ownership of property, improvements made by Tenant to the Leased Premises or the Outside Areas, improvements made by Landlord for Tenant’s use within the Leased Premises or the Outside Areas, Tenant’s use (or estimated use) of public facilities or services or Tenant’s consumption (or estimated consumption) of public utilities, energy, water or other resources (collectively, “Tenant’s Interest”). Upon demand by Landlord, Tenant shall furnish Landlord with satisfactory evidence of these payments. If any such taxes, assessments, fees or public charges are levied against Landlord, Landlord’s property, the Building or the Property, or if the assessed value of the Building or the Property is increased by the inclusion therein of a value placed upon Tenant’s Interest, regardless of the validity thereof, Landlord shall have the right to require Tenant to pay such taxes, and if not paid and satisfactory evidence of payment delivered to Landlord at least ten days prior to delinquency, then Landlord shall have the right to pay such taxes on Tenant’s behalf and to invoice Tenant for the same. Tenant shall, within the earlier to occur of (a) thirty (30) days of the date it receives an invoice from Landlord setting forth the amount of such taxes, assessments, fees, or public charge so levied, or (b) the due date of such invoice, pay to Landlord, as Additional Rent, the amount set forth in such invoice. Failure by Tenant to pay the amount so invoiced within such time period shall be conclusively deemed a default by Tenant under this Lease. Tenant shall have the right to bring suit in any court of competent jurisdiction to recover from the taxing authority the amount of any such taxes, assessments, fees or public charges so paid.

13.2 Holding Over. This Lease shall terminate without further notice on the Lease Expiration Date (as set forth in Article 1). Any holding over by Tenant after expiration of the Lease Term shall neither constitute a renewal nor extension of this Lease nor give Tenant any rights in or to the Leased Premises except as expressly provided in this Paragraph. Any such holding over to which Landlord has consented shall be construed to be a tenancy from month to month, on the same terms and conditions herein specified insofar as applicable, except that the Base Monthly Rent shall be increased to an amount equal to one hundred fifty percent (150%) of the Base Monthly Rent payable during the last full month immediately preceding such holding over. Tenant acknowledges that if Tenant holds over without Landlord’s consent, such holding over may compromise or otherwise affect Landlord’s ability to enter into new leases with prospective tenants regarding the Leased Premises. Therefore, if Tenant fails to surrender the Leased Premises upon the expiration or termination of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from and against all claims resulting from such failure, including, without limiting the foregoing, any claims made by any succeeding tenant

19.

founded upon such failure to surrender, and any losses suffered by Landlord, including lost profits, resulting from such failure to surrender.

13.3 Subordination To Mortgages. This Lease is subject to and subordinate to all ground leases, mortgages and deeds of trust which affect the Building or the Property and which are of public record as of the Effective Date of this Lease, and to all renewals, modifications, consolidations, replacements and extensions thereof. However, if the lessor under any such ground lease or any lender holding any such mortgage or deed of trust shall advise Landlord that it desires or requires this Lease to be made prior and superior thereto, then, upon written request of Landlord to Tenant, Tenant shall promptly execute, acknowledge and deliver any and all customary or reasonable documents or instruments which Landlord and such lessor or lender deems necessary or desirable to make this Lease prior thereto. Tenant hereby consents to Landlord’s ground leasing the land underlying the Building or the Property and/or encumbering the Building or the Property as security for future loans on such terms as Landlord shall desire, all of which future ground leases, mortgages or deeds of trust shall be subject to and subordinate to this Lease. However, if any lessor under any such future ground lease or any lender holding such future mortgage or deed of trust shall desire or require that this Lease be made subject to and subordinate to such future ground lease, mortgage or deed of trust, then Tenant agrees, within fifteen (15) days after Landlord’s written request therefor, to execute, acknowledge and deliver to Landlord any and all documents or instruments reasonably requested by Landlord or by such lessor or lender as may be necessary or proper to assure the subordination of this Lease to such future ground lease, mortgage or deed of trust, but only if such lessor or lender agrees to recognize Tenant’s rights under this Lease and agrees not to disturb Tenant’s quiet possession of the Leased Premises so long as Tenant is not in default under this Lease. If Landlord assigns the Lease as security for a loan, Tenant agrees to execute such documents as are reasonably requested by the lender and to provide reasonable provisions in the Lease protecting such lender’s security interest which are customarily required by institutional lenders making loans secured by a deed of trust.

13.4 Tenant’s Attornment Upon Foreclosure. Tenant shall, upon request, attorn (i) to any purchaser of the Building or the Property at any foreclosure sale or private sale conducted pursuant to any security instruments encumbering the Building or the Property, (ii) to any grantee or transferee designated in any deed given in lieu of foreclosure of any security interest encumbering the Building or the Property, or (iii) to the lessor under an underlying ground lease of the land underlying the Building or the Property, should such ground lease be terminated; provided that such purchaser, grantee or lessor recognizes Tenant’s rights under this Lease.

13.5 Mortgagee Protection. In the event of any default on the part of Landlord, Tenant will give notice by registered mail to any Lender or lessor under any underlying ground lease who shall have requested, in writing, to Tenant that it be provided with such notice, and Tenant shall offer such Lender or lessor a reasonable opportunity to cure the default, including time to obtain possession of the Leased Premises by power of sale or judicial foreclosure or other appropriate legal proceedings if reasonably necessary to effect a cure.

13.6 Estoppel Certificate. Tenant will, following any request by Landlord, promptly execute and deliver to Landlord an estoppel certificate substantially in form attached as Exhibit D, (i) certifying that this Lease is unmodified and in full force and effect, or, if modified, stating the nature of such modification and certifying that this Lease, as so modified, is in full force and effect, (ii) stating the date to which the rent and other charges are paid in advance, if any, (iii) acknowledging that there are not, to Tenant’s knowledge, any uncured defaults on the part of Landlord hereunder, or specifying such defaults if any are claimed, and (iv) certifying such other information about this Lease as may be reasonably requested by Landlord, its Lender or prospective lenders, investors or purchasers of the Building or the Property. Tenant’s failure to execute and deliver such estoppel certificate within ten days after Landlord’s written request therefor shall, at Landlord’s option, be a material default by Tenant under this Lease, and Landlord shall have all of the rights and remedies available to Landlord as Landlord would otherwise have in the case of any other material default by Tenant, including the right to terminate this Lease and ▇▇▇ for damages proximately caused thereby, it being agreed and understood by Tenant that Tenant’s failure to so deliver such estoppel certificate in a timely manner could result in Landlord being unable to perform committed obligations to other third parties which were made by Landlord in reliance upon this covenant of Tenant. Landlord and Tenant intend that any statement delivered pursuant to this paragraph may be relied upon by any Lender or purchaser or prospective Lender or purchaser of the Building, the Property, or any interest in them.

13.7 Tenant’s Financial Information. Tenant shall, within fifteen (15) business days after Landlord’s request therefor, deliver to Landlord a copy of Tenant’s (and any guarantor’s) last prepared financial statements (including a balance sheet, income statement and statement of cash flow, all prepared in accordance with generally accepted accounting principles) and any such other information reasonably requested by Landlord regarding Tenant’s financial condition. Landlord shall be entitled to disclose such financial statements or other information to its Lender, to any present or prospective principal of or investor in Landlord, or to any prospective Lender or purchaser of the Building, the Property, or any portion thereof or interest therein. Any such financial statement or other information which is marked “confidential” or “company secrets” (or is otherwise similarly marked by Tenant) shall be confidential and shall not be disclosed by Landlord to any third party except as specifically provided in this paragraph, unless the same becomes a part of the public domain without the fault of Landlord.

13.8 Transfer By Landlord. Landlord and its successors in interest shall have the right to transfer their interest in the Building, the Property, or any portion thereof at any time and to any person or entity. In the event of any such transfer, the Landlord originally named herein (and in the case of any subsequent transfer, the transferor), from the date of such transfer, (i) shall be automatically relieved, without any further act by any person or entity, of all liability for the performance of the obligations of the Landlord hereunder which may accrue after the date of such transfer and (ii) shall be relieved of all liability for the performance of the obligations of the Landlord hereunder which have accrued before the date of transfer if its transferee agrees to assume and perform all such prior obligations of the Landlord hereunder. Tenant shall attorn to any such transferee. After the date of any such transfer, the term “Landlord” as used herein shall mean the transferee of such interest in the Building or the Property.

20.

13.9 Force Majeure. The obligations of each of the parties under this Lease (other than the obligations to pay money) shall be temporarily excused if such party is prevented or delayed in performing such obligations by reason of any strikes, lockouts or labor disputes; government restrictions, regulations, controls, action or inaction; civil commotion; or extraordinary weather, fire or other acts of God.

13.10 Notices. Any notice required or permitted to be given under this Lease shall be in writing and (i) personally delivered, (ii) sent by United States mail, registered or certified mail, postage prepaid, return receipt requested, (iii) sent by Federal Express or similar nationally recognized overnight courier service, or (iv) transmitted by facsimile with a hard copy sent within one (1) business day by any of the foregoing means, and in all cases addressed as follows, and such notice shall be deemed to have been given upon the date of actual receipt or delivery (or refusal to accept delivery) at the address specified below (or such other addresses as may be specified by notice in the foregoing manner) as indicated on the return receipt or air ▇▇▇▇:

13.11 Attorneys’ Fees. In the event any party shall bring any action, arbitration proceeding or legal proceeding alleging a breach of any provision of this Lease, to recover rent, to terminate this Lease, or to enforce, protect, determine or establish any term or covenant of this Lease or rights or duties hereunder of either party, the prevailing party shall be entitled to recover from the non-prevailing party as a part of such action or proceeding, or in a separate action for that purpose brought within one year from the determination of such proceeding, reasonable attorneys’ fees, expert witness fees, court costs and other reasonable expenses incurred by the prevailing party.

13.12 Definitions. Any term that is given a special meaning by any provision in this Lease shall, unless otherwise specifically stated, have such meaning wherever used in this Lease or in any Addenda or amendment hereto. In addition to the terms defined in Article 1, the following terms shall have the following meanings:

(a) Real Property Taxes. The term “Real Property Tax” or “Real Property Taxes” shall each mean Tenant’s Expense Share of (i) all taxes, assessments, levies and other charges of any kind or nature whatsoever, general and special, foreseen and unforeseen (including all instruments of principal and interest required to pay any general or special assessments for public improvements and any increases resulting from reassessments caused by any change in ownership or new construction), now or hereafter imposed by any governmental or quasi-governmental authority or special district having the direct or indirect power to tax or levy assessments, which are levied or assessed for whatever reason against the Property or any portion thereof, or Landlord’s interest herein, or the fixtures, equipment and other property of Landlord that is an integral part of the Property and located thereon, or Landlord’s business of owning, leasing or managing the Property or the gross receipts, income or rentals from the Property, (ii) all charges, levies or fees imposed by any governmental authority against Landlord by reason of or based upon the use of or number of parking spaces within the Property, the amount of public services or public utilities used or consumed (e.g. water, gas, electricity, sewage or waste water disposal) at the Property, the number of person employed by tenants of the Property, the size (whether measured in area, volume, number of tenants or whatever) or the value of the Property, or the type of use or uses conducted within the Property, and all costs and fees (including attorneys’ fees) reasonably incurred by Landlord in contesting any Real Property Tax and in negotiating with public authorities as to any Real Property Tax. If, at any time during the Lease Term, the taxation

21.

or assessment of the Property prevailing as of the Effective Date of this Lease shall be altered so that in lieu of or in addition to any the Real Property Tax described above there shall be levied, awarded or imposed (whether by reason of a change in the method of taxation or assessment, creation of a new tax or charge, or any other cause) an alternate, substitute, or additional use or charge (i) on the value, size, use or occupancy of the Property or Landlord’s interest therein or (ii) on or measured by the gross receipts, income or rentals from the Property, or on Landlord’s business of owning, leasing or managing the Property or (iii) computed in any manner with respect to the operation of the Property, then any such tax or charge, however designated, shall be included within the meaning of the terms “Real Property Tax” or “Real Property Taxes” for purposes of this Lease. If any Real Property Tax is partly based upon property or rents unrelated to the Property, then only that part of such Real Property Tax that is fairly allocable to the Property shall be included within the meaning of the terms “Real Property Tax” or “Real Property Taxes.” Notwithstanding the foregoing, the terms “Real Property Tax” or “Real Property Taxes” shall not include estate, inheritance, transfer, gift or franchise taxes of Landlord or the federal or state income tax imposed on Landlord’s income from all sources, or penalties or interest caused by Landlord’s late payment of Real Property Taxes, unless due to Tenant’s failure to pay Additional Rent when due hereunder. In the event Landlord has elected to have Tenant pay Real Property taxes directly to the taxing authority in accordance with Paragraph 3.2 hereof, Tenant shall be liable for all penalties or interest caused by Tenant’s late payment.

(b) Landlord’s Insurance Costs. The term “Landlord’s Insurance Costs” shall mean Tenant’s Expense Share of the costs to Landlord to carry and maintain the policies of fire and property damage insurance for the Building and the Property and general liability and any other insurance required or permitted to be carried by Landlord pursuant to Article 9, together with any deductible amounts paid by Landlord upon the occurrence of any insured casualty or loss.

(c) Property Maintenance Costs. The term “Property Maintenance Costs” shall mean Tenant’s Expense Share of all costs and expenses (except Landlord’s Insurance Costs and Real Property Taxes) paid or incurred by Landlord in protecting, operating, maintaining, repairing and preserving the Property and all parts thereof, including without limitation, (i) market rate professional management fees in the amount of 3% of gross rent received by Landlord, (ii) the amortizing portion of any costs incurred by Landlord in the making of any modifications, alterations or improvements required by any governmental authority as set forth in Article 6, which are so amortized during the Lease Term, and (iii) such other costs as may be paid or incurred with respect to operating, maintaining, and preserving the Property, such as repairing and resurfacing the exterior surfaces of the Building (including roofs), repairing and resurfacing paved areas, repairing and replacing structural parts of the Building, and repairing and replacing, when necessary, electrical, plumbing, heating, ventilating and air conditioning systems serving the Building. To the extent any of the foregoing items described in clause (iii) constitute capital repairs or replacements under generally accepted accounting principles, consistently applied, then only the amortizing portion of such capital repairs or replacements shall constitute Property Maintenance Costs; such amortization shall be over the useful life of the applicable repair or replacement, and shall employ an interest rate equal to the sum of that rate quoted by ▇▇▇▇▇ Fargo Bank, N.T. & S.A. from time to time as its prime rate, plus two percent (2%). Notwithstanding the foregoing provisions of this Paragraph 13.12(c), the following are specifically excluded from the definition of Property Maintenance Costs and Tenant shall have no obligation to pay directly or reimburse Landlord for all or any portion of the following except to the extent any of the following are caused by the actions or inactions of Tenant, or result from the failure of Tenant to comply with the terms of this Lease: (a) legal and auditing fees (other than those fees reasonably incurred in connection with the maintenance and operation of all or any portion the Building), leasing commissions, advertising expenses, and other costs incurred in connection with the original leasing of the Property or future re-leasing of any portion of the Building; (b) depreciation of the Building or any other improvements situated within the Project; (c) any items for which Landlord is actually reimbursed by insurance or by direct reimbursement by Tenant or any other party; (d) costs of repairs or other work necessitated by fire, windstorm or other casualty (excluding any deductibles) and/or costs of repair or other work necessitated by the exercise of the right of eminent domain to the extent insurance proceeds or a condemnation award, as applicable, is actually received by Landlord for such purposes; (e) any payments under a ground lease or master lease; (f) the wages and benefits of any employee who does not devote substantially all of his or her employed time to the Property unless such wages and benefits are prorated to reflect time spent on operating and managing the Property vis-à-vis time spent on matters unrelated to operating and managing the Property; (g) wages and/or benefits attributable to personnel above the level of property manager or property engineer shall not be included; (h) political and charitable contributions by Landlord; (h) principal and interest payments on any debt secured by the Property; (i) the costs of tenant improvements made for other tenants of the Property; (j) any expense resulting from the gross negligence of Landlord, its agents or employees, or, to the extent Landlord is entitled to reimbursement for such costs, to remedy damage caused by or resulting from the gross negligence of any tenants in the Project, including their agents and employees; and (k) costs associated with the operation of the business of the entity which constitutes Landlord, as the same are distinguished from the costs of operation of the Property.

(d) Property Operating Expenses. The term “Property Operating Expenses” shall mean and include all Real Property Taxes, plus all Landlord’s Insurance Costs, plus all Property Maintenance Costs.

(e) Law. The term “Law” shall mean any judicial decisions and any statute, constitution, ordinance, resolution, regulation, rule, administrative order, or other requirements of any municipal, county, state, federal, or other governmental agency or authority having jurisdiction over the parties to this Lease, the Leased Premises, the Building or the Property, or any of them, in effect either at the Effective Date of this Lease or at any time during the Lease Term, including, without limitation, any regulation, order, or policy of any quasi-official entity or body (e.g. a board of fire examiners or a public utility or special district).

(f) Lender. The term “Lender” shall mean the holder of any promissory note or other evidence of indebtedness secured by the Property or any portion thereof.

22.

(g) Private Restrictions. The term “Private Restrictions” shall mean (as they may exist from time to time) any and all covenants, conditions and restrictions, private agreements, easements, and any other recorded documents or instruments affecting the use of the Property, the Building, the Leased Premises, or the Outside Areas.

(h) Rent. The term “Rent” shall mean collectively Base Monthly Rent and all Additional Rent.

13.13 General Waivers. One party’s consent to or approval of any act by the other party requiring the first party’s consent or approval shall not be deemed to waive or render unnecessary the first party’s consent to or approval of any subsequent similar act by the other party. No waiver of any provision hereof, or any waiver of any breach of any provision hereof, shall be effective unless in writing and signed by the waiving party. The receipt by Landlord of any rent or payment with or without knowledge of the breach of any other provision hereof shall not be deemed a waiver of any such breach. No waiver of any provision of this Lease shall be deemed a continuing waiver unless such waiver specifically states so in writing and is signed by both Landlord and Tenant. No delay or omission in the exercise of any right or remedy accruing to either party upon any breach by the other party under this Lease shall impair such right or remedy or be construed as a waiver of any such breach theretofore or thereafter occurring. The waiver by either party of any breach of any provision of this Lease shall not be deemed to be a waiver of any subsequent breach of the same or any other provisions herein contained.

13.14 Miscellaneous. Should any provisions of this Lease prove to be invalid or illegal, such invalidity or illegality shall in no way affect, impair or invalidate any other provisions hereof, and such remaining provisions shall remain in full force and effect. Time is of the essence with respect to the performance of every provision of this Lease in which time of performance is a factor. Any copy of this Lease which is executed by the parties shall be deemed an original for all purposes. This Lease shall, subject to the provisions regarding assignment, apply to and bind the respective heirs, successors, executors, administrators and assigns of Landlord and Tenant. The term “party” shall mean Landlord or Tenant as the context implies. If Tenant consists of more than one person or entity, then all members of Tenant shall be jointly and severally liable hereunder. Submission of this Lease for review, examination or signature by Tenant does not constitute an offer to lease, a reservation of or an option for lease, and notwithstanding any inconsistent language contained in any other document, this Lease is not effective as a lease or otherwise until execution and delivery by both Landlord and Tenant. This Lease shall be construed and enforced in accordance with the Laws of the State in which the Leased Premises are located. The captions in this Lease are for convenience only and shall not be construed in the construction or interpretation of any provision hereof. When the context of this Lease requires, the neuter gender includes the masculine, the feminine, a partnership, corporation, limited liability company, joint venture, or other form of business entity, and the singular includes the plural. The terms “must,” “shall,” “will,” and “agree” are mandatory. The term “may” is permissive. When a party is required to do something by this Lease, it shall do so at its sole cost and expense without right of reimbursement from the other party unless specific provision is made therefor. Where Landlord’s consent is required hereunder, the consent of any Lender shall also be required (if required by any loan documents between Landlord and Lender). Landlord and Tenant shall both be deemed to have drafted this Lease, and the rule of construction that a document is to be construed against the drafting party shall not be employed in the construction or interpretation of this Lease. Where Tenant is obligated not to perform any act or is not permitted to perform any act, Tenant is also obligated to restrain any others reasonably within its control, including agents, invitees, contractors, subcontractors and employees, from performing such act. Landlord shall not become or be deemed a partner or a joint venturer with Tenant by reason of any of the provisions of this Lease.

ARTICLE 14

BROKERS AND ENTIRE AGREEMENT

If Tenant is a corporation, each individual executing this Lease on behalf of such corporation represents and warrants that Tenant is validly formed and duly authorized and existing, that Tenant is qualified to do business in the State in which the Leased Premises are located, that Tenant has the full right and legal authority to enter into this Lease, and that he or she is duly authorized to execute and deliver this Lease on behalf of Tenant in accordance with its terms. Tenant shall, within thirty days after execution of this Lease, deliver to Landlord a certified copy of the resolution of its board of directors authorizing or ratifying the execution of this Lease and if Tenant fails to do so, Landlord at its sole election may elect to terminate this Lease.

14.2 Brokerage Commissions. Tenant and Landlord each represent, warrant and agree that they have not had any dealings with any real estate broker(s), leasing agent(s), finder(s) or salesmen, other than the Brokers (as named in Article 1) with respect to the lease by it of the Leased Premises pursuant to this Lease. Each of Landlord and Tenant will indemnify, defend with competent counsel, and hold the other harmless from any liability for the payment of any real estate brokerage commissions, leasing commissions or finder’s fees claimed by any other real estate broker(s), leasing agent(s), finder(s), or salesmen due to the other party’s breach of the representations, warranties and covenants made by such party in this Paragraph 14.2.

No subsequent changes, modifications or additions to this Lease shall be binding upon the parties unless in writing and signed by both Landlord and Tenant.

Tenant acknowledges that neither Landlord nor any of its agents made any representations or warranties respecting the Property, the Building or the Leased Premises, upon which Tenant relied in entering into the Lease, which are not expressly set forth in this Lease.

23.

Tenant’s intended use under existing Law, or (ii) the suitability of the Leased Premises for the conduct of Tenant’s business, or (iii) the exact square footage of the Leased Premises, and that Tenant relies solely upon its own investigations with respect to such matters. Tenant expressly waives any and all claims for damage by reason of any statement, representation, warranty, promise or other agreement of Landlord or Landlord’s agent(s), if any, not contained in this Lease or in any Exhibit attached hereto.

ARTICLE 15

TELEPHONE SERVICE

Notwithstanding any other provision of this Lease to the contrary:

(a) So long as the entirety of the Leased Premises is leased to Tenant:

(i) Landlord shall have no responsibility for providing to Tenant any telephone equipment, including wiring, within the Leased Premises or for providing telephone service or connections from the utility to the Leased Premises; and

(ii) Landlord makes no warranty as to the quality, continuity or availability of the telecommunications services in the Building, and Tenant hereby waives any claim against Landlord for any actual or consequential damages (including damages for loss of business) in the event Tenant’s telecommunications services in any way are interrupted, damaged or rendered less effective, except to the extent caused by the grossly negligent or willful act or omission by Landlord, its agents or employees. Tenant accepts the telephone equipment (including, without limitation, the INC, as defined below) in its “AS-IS” condition, and Tenant shall be solely responsible for contracting with a reliable third party vendor to assume responsibility for the maintenance and repair thereof (which contract shall contain provisions requiring such vendor to inspect the INC periodically (the frequency of such inspections to be determined by such vendor based on its experience and professional judgment), and requiring such vendor to meet local and federal requirements for telecommunications material and workmanship). Except for Landlord’s active negligence or willful misconduct, Landlord shall not be liable to Tenant and Tenant waives all claims against Landlord whatsoever, whether for personal injury, property damage, loss of use of the Leased Premises, or otherwise, due to the interruption or failure of telephone services to the Leased Premises. Except for Landlord’s active negligence or willful misconduct, Tenant hereby holds Landlord harmless and agrees to indemnify, protect and defend Landlord from and against any liability for any damage, loss or expense due to any failure or interruption of telephone service to the Leased Premises for any reason.

(b) At such time as the entirety of the Leased Premise is no longer leased to Tenant, Landlord shall in its sole discretion have the right, by written notice to Tenant, to elect to assume limited responsibility for INC, as provided below, and upon such assumption of responsibility by Landlord, this subparagraph (b) shall apply prospectively.

(i) Landlord shall provide Tenant access to such quantity of pairs in the Building intra-building network cable (“INC”) as is determined to be available by Landlord in its reasonable discretion. Tenant’s access to the INC shall be solely by arrangements made by Tenant, as Tenant may elect, directly with Pacific ▇▇▇▇ or Landlord (or such vendor as Landlord may designate), and Tenant shall pay all reasonable charges as may be imposed in connection therewith. Pacific ▇▇▇▇’▇ charges shall be deemed to be reasonable. Subject to the foregoing, Landlord shall have no responsibility for providing to Tenant any telephone equipment, including wiring, within the Leased Premises or for providing telephone service or connections from the utility to the Leased Premises, except as required by law.

(ii) Tenant shall not alter, modify, add to or disturb any telephone wiring in the Leased Premises or elsewhere in the Building without the Landlord’s prior written consent, which consent shall not be unreasonably withheld. Tenant shall be liable to Landlord for any damage to the telephone wiring in the Building due to the act, negligent or otherwise, of Tenant or any employee, contractor or other agent of Tenant. Tenant shall have no access to the telephone closets within the Building, except in the manner and under procedures established by Landlord. Tenant shall promptly notify Landlord of any actual or suspected failure of telephone service to the Leased Premises.

(iii) All costs incurred by Landlord for the installation, maintenance, repair and replacement of telephone wiring in the Building shall be a Property Maintenance Cost.

(iv) Landlord makes no warranty as to the quality, continuity or availability of the telecommunications services in the Building, and Tenant hereby waives any claim against Landlord for any actual or consequential damages (including damages for loss of business) in the event Tenant’s telecommunications services in any way are interrupted, damaged or rendered less effective, except to the extent caused by the actively negligent or willful act or omission by Landlord, its agents or employees. Tenant acknowledges that Landlord meets its duty of care to Tenant with respect to the Building INC by contracting with a reliable third party vendor to assume responsibility for the maintenance and repair thereof (which contract shall contain provisions requiring such vendor to inspect the INC periodically (the frequency of such inspections to be determined by such vendor based on its experience and professional judgment), and requiring such vendor to meet local and federal requirements for telecommunications material and workmanship). Subject to the foregoing, and except to the extent of landlord’s active negligence or willful misconduct, Landlord shall not be liable to Tenant and Tenant waives all claims against Landlord whatsoever, whether for personal injury, property damage, loss of use of the Leased Premises, or otherwise, due to the interruption or failure of telephone services to the Leased Premises. Except for Landlord’s active negligence or willful misconduct, Tenant hereby holds Landlord harmless and agrees to indemnify, protect and defend Landlord from and against any liability for any damage, loss or expense due to any failure or interruption of telephone service to the Leased Premises for any reason.
