To the extent Tenant is entitled to abatement because of an event covered by Sections 16 or 17 of this Lease, then the Eligibility Period shall not be applicable. Except as provided in this Section 7.03, nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder.

Tenant hereby waives any and all rights under and benefits of subsection 1 of Section 1932, and Sections 1941 and 1942 of the California Civil Code, or any similar or successor Laws now or hereinafter in effect.

9.03 Tenant shall not make alterations, repairs, additions or improvements or install any Cable (collectively referred to as “Alterations”) without first obtaining the written consent of Landlord in each instance, which consent shall not be unreasonably withheld unless a “Design Problem”, as that term is defined, below, exists, in which event Landlord may withhold its consent in its sole and absolute discretion and shall be granted or denied (any denial shall include a list of objections and the reasons therefor) within 10 Business Days following Landlord’s receipt of Tenant’s notice. If Landlord fails to timely respond to Tenant within such ten (10) Business Day period, then Tenant shall deliver a second notice requesting Landlord’s response to such consent request and stating that Landlord’s failure to respond shall be deemed approved and if Landlord thereafter fails to respond within five (5) Business Days, Landlord’s approval shall be deemed granted. A “Design Problem” is defined as, and will be deemed to exist if such Alteration may (i) affect the exterior appearance of the Premises or Building; (ii) adversely affect the Building Structure; (iii) adversely affect the Base Building Systems; (iv) unreasonably interfere with any other occupant’s normal and customary office operation, (v) adversely affect the certificate of occupancy issued for the Building, or (vi) fail to comply with applicable Laws. Notwithstanding the foregoing, Landlord’s consent shall not be required for any particular Alteration that (A) does not create or otherwise constitute a Design Problem, (B) is not inconsistent with Tenant’s use of the Premises for the Permitted Use, and (C) does not involve the expenditure of more than $50,000.00 (a “Permitted Alterat ion”); provided, however, that Tenant shall deliver written notice of such Permitted Alteration (and any information reasonably requested by Landlord relating to such Permitted Alteration) to Landlord at least ten (10) Business Days prior to the commencement of construction of such Permitted Alteration. Permitted Alterations shall otherwise be subject to all the other provisions of this Section 9.03. Prior to starting work, Tenant shall furnish Landlord with plans and specifications reasonably acceptable to Landlord; names of contractors reasonably acceptable to Landlord (provided that Landlord may designate specific contractors with respect to Base Building, provided that they shall be competitively priced and reasonably available); required permits and approvals; evidence of contractor’s and subcontractor’s insurance in amounts reasonably required by Landlord and naming Landlord as an additional insured; and any security for performance in amounts reasonably requir ed by Landlord, provided that the Tenant originally named in this Lease shall not be obligated to provide any security. Changes to the plans and specifications must also be submitted to Landlord for its approval, which shall not be unreasonably withheld, except in connection with a Design Problem. If Landlord fails to timely respond to Tenant within such three (3) Business Days after Tenant’s request for approval of any such change, then Tenant shall deliver a second notice requesting Landlord’s response to such consent request and stating that Landlord’s failure to respond shall be deemed approved and if Landlord thereafter fails to respond within two (2) Business Days, Landlord’s approval to such change shall be deemed granted. Alterations shall be constructed in a good and workmanlike manner using materials of a quality that is at least equal to the quality standards reasonably designated by Landlord as the minimum standard for the Building. Tenant shall reimburse Landlord within 30 days after receipt of an invoice for any sums paid by Landlord for third party examination of Tenant’s plans for non-Permitted Alterations. In addition, Tenant shall pay Landlord a fee for Landlord’s oversight and coordination of any non-Permitted Alterations equal to 3% of the cost of such Alterations. Upon completion, Tenant shall furnish “as-built” plans for non-Permitted Alterations, completion affidavits and full and final waivers of lien. Landlord’s approval of an Alteration shall not be deemed a representation by Landlord that the Alteration complies with Law. Construction of the Initial Alterations shall be governed by the terms and conditions of Exhibit C and not this Section 9.

9.04 Tenant, as part of the Initial Alterations or thereafter, may install supplemental heating, ventilation and air conditioning systems in the Premises (the “Supplemental HVAC Unit”), which Supplemental HVAC Unit shall be subject to the prior reasonable approval of Landlord, including, without limitation, the location of the Supplemental HVAC Unit within the Premises. The Supplemental HVAC System may be connected into the Building’s chilled water system and Tenant shall be responsible for the cost of all chilled water utilized by such Supplemental HVAC Unit. The manner in which Tenant connects to Landlord’s chilled water loop, including, without limitation, the routing of any water lines, shall be subject to Landlord’s prior written approval, which shall not be unreasonably withheld or delayed. Tenant shall be responsible for the cost of all electricity consumed in connection with the operation of such Supplemental HVAC Unit and for the cost of installing a submeter to measure such electrical consumption. In addition and subject to the terms of this Section 9.04, Tenant shall be permitted to use the Supplemental HVAC units that currently exist in the Premises. Such use shall be at Tenant’s sole risk, cost and expense, and Landlord shall have no responsibility with respect to Tenant’s use of the existing Supplemental HVAC Units. Tenant, at its sole cost and expense, shall procure and maintain in full force and effect, a contract (the “Service Contract”) for the service, maintenance, repair and replacement of the Supplemental HVAC Unit with a HVAC service and maintenance contracting firm reasonably acceptable to Landlord. Tenant shall follow all reasonable recommendations of said contractor for the maintenance, repair and replacement of the

8

Supplemental HVAC Unit. The Service Contract shall provide that the contractor shall perform inspections of the Supplemental HVAC Unit at intervals of not less than six (6) months and that having made such inspections, said contractor shall furnish a complete report of any defective conditions found to be existing with respect to the Supplemental HVAC Unit, together with any recommendations for maintenance, repair and/or replacement thereof. Said report shall be furnished to Tenant with a copy to Landlord. Upon the expiration or earlier termination of this Lease, title and ownership of said Supplemental HVAC Unit shall pass to Landlord.

9.05. Tenant, at its sole cost and expense, subject to reimbursement from the Allowance, may install and maintain additional security systems to limit/monitor access to the Premises (“Tenant’s Security System”). Landlord shall not be obligated to provide janitorial services for any limited access areas unless it is provided access thereto. Prior to installation, Tenant must obtain Landlord’s approval of Tenant’s Security System, which approval shall not be unreasonably withheld, conditioned or delayed. Tenant’s Security System shall be compatible with the Building’s access systems and comply with all Laws. In the event that there are subsequent changes to the Building’s access control systems, Landlord shall not be responsible for altering Tenant’s Security System to be compatible therewith.

10. Entry by Landlord.

Landlord may enter the Premises to inspect, show or clean the Premises or to perform or facilitate the performance of repairs, alterations or additions to the Premises or any portion of the Building. Except in emergencies that threaten injury to property or persons or to provide recurring Building services, Landlord shall provide Tenant with no less than 24 hours prior written notice of entry and shall use reasonable efforts to minimize any interference with Tenant’s use of the Premises. Notwithstanding the foregoing, except in emergency situations as determined by Landlord, Landlord shall exercise reasonable efforts to perform any entry into the Premises in a manner that is reasonably designed to minimize interference with the operation of Tenant’s business in, or Tenant’s access to, the Premises, and if Landlord performs any work in the Premises during Building Ser vice Hours, then Landlord shall use commercially reasonable efforts to schedule such work to minimize interference with the operation of Tenant’s business in, or Tenant’s access to, the Premises, provided that Tenant reasonably cooperates with Landlord’s scheduling efforts. Landlord acknowledges and agrees that Tenant may require that Landlord be accompanied by an employee of Tenant during any such entry into the Premises by Landlord; provided, however, that in no event shall the unavailability of such escort at the time that Landlord is permitted to enter the Premises delay Landlord’s entry into the Premises as permitted hereunder. If reasonably necessary for the protection and safety of Tenant and its employees, Landlord may temporarily close all or a portion of the Premises to perform repairs, alterations and additions. However, except in emergencies, Landlord will not close the Premises if the work can reasonably be completed on weekends and after Building Service Hours. E xcept as expressly provided in this Lease, entry by Landlord shall not constitute a constructive eviction or entitle Tenant to an abatement or reduction of Rent.

11. Assignment and Subletting.

11.01 Except in connection with a Permitted Transfer (defined in Section 11.04), Tenant shall not assign, sublease, transfer or encumber any interest in this Lease or allow any third party to use any portion of the Premises (collectively or individually, a “Transfer”) without the prior written consent of Landlord, which consent shall not be unreasonably withheld or conditioned if Landlord does not exercise its recapture rights under Section 11.02. Landlord shall grant or deny its consent to a proposed Transfer within 10 Business Days following Tenant’s request for Landlord’s approval as set forth herein. If Landlord fails to timely respond to Tenant within such 10 Business Day period, then Tenant shall deliver a second notice requesting Landlord’s response to its consent request and stating that Landlord’s failure to respond shal l be deemed an approval. If Landlord thereafter fails to respond to such second notice within 5 Business Days, Landlord’s consent shall be deemed granted. Notwithstanding the foregoing, Landlord will not withhold its consent solely because the proposed subtenant or assignee is an occupant of the Building if Landlord does not have space available for lease in the Building that is comparable to the space Tenant desires to sublet or assign. Landlord shall be deemed to have comparable space if it has, or will have, space available on any floor of the Building that is approximately the same size as the space Tenant desires to sublet or assign within 6 months of the proposed commencement of the proposed sublease or assignment. Except as provided below with respect to a Permitted Transfer, if the control of any entity which controls the voting shares/rights of Tenant changes at any time (i.e., more than 50% of the voting shares), such change of ownership or control shall constitute a Transfer unless (i) T enant is an entity whose outstanding stock is listed on a recognized securities exchange or if at least 80% of its voting stock is owned by another entity, the voting stock of which is so listed or (ii) the stock of any entity which controls the voting shares/rights of Tenant is listed on a recognized securities exchange. Tenant hereby waives the provisions of Section 1995.310 of the California Civil Code, or any similar or successor Laws, now or hereinafter in effect, and all other remedies, including, without limitation, any right at law or equity to terminate this Lease, on its own behalf and, to the extent permitted under all applicable Laws, on behalf of the proposed transferee. Any attempted Transfer in violation of this Section is

9

voidable by Landlord. In no event shall any Transfer, including a Permitted Transfer, release or relieve Tenant from any obligation under this Lease.

11.02 Tenant shall provide Landlord with financial statements for the proposed transferee which are prepared in the ordinary course of its business, a fully executed copy of the proposed assignment, sublease or other Transfer documentation and such other information as Landlord may reasonably request, provided that Landlord shall have no right to review any documents relating to the sale of Tenant’s business so long as such documents do not contain any terms applicable to the assignment or sublease. Within 10 Business Days after receipt of the required information and documentation, Landlord shall either: (a) consent to the Transfer by execution of a consent agreement in a form reasonably designated by Landlord; (b) reasonably refuse to consent to the Transfer in writing in accordance with this Section 11, including the reasons for such refusal; or (c) except in connection with a Permitted Transfer or a Pre-Approved Transfer or in the event of an assignment of this Lease or subletting of more than 51% of the Rentable Area of the Premises for more than 50% of the remaining Term (excluding unexercised options), recapture the portion of the Premises that Tenant is proposing to Transfer in accordance with this Section 11.02 below. Tenant shall pay Landlord a review fee equal to the actual out-of-pocket costs, expenses and attorney fees incurred for Landlord’s review of any Permitted Transfer or requested Transfer, including the preparation and negotiation of any consent required of Landlord related to a Transfer. Notwithstanding the foregoing, provided that neither the Tenant nor the proposed transferee requests any changes to this Lease or any material changes to Landlord’s commercially reasonable standard form of consent in connection with the proposed Transfer, such costs and expenses shall not exceed $1,500.00. Notwithstanding anythi ng to the contrary contained in this Section 11 (but not with respect to a Permitted Transfer or a Pre-Approved Transfer), in the event Tenant contemplates an assignment of this Lease or a subletting of more than 51% of the Rentable Square Footage of the Premises for more than 50% of the remaining Term (excluding unexercised options), Tenant shall give Landlord notice (the Intention to Transfer Notice”) of such contemplated Transfer (whether or not the contemplated transferee or the terms of such contemplated Transfer have been determined). The Intention to Transfer Notice shall specify the portion of and amount of rentable square feet of the Premises which Tenant intends to Transfer (the “Contemplated Transfer Space”), the contemplated date of commencement of the Contemplated Transfer (the “Contemplated Effective Date”), and the contemplated length of the term of such contemplated Transfer, and shall specify that such Intention to Transfer Notice is d elivered to Landlord pursuant to this Section 11.02 in order to allow Landlord to elect to recapture the Contemplated Transfer Space. Thereafter, Landlord shall have the option, by giving written notice to Tenant within ten (10) Business Days after receipt of any Intention to Transfer Notice, to recapture the Contemplated Transfer Space. Such recapture shall cancel and terminate this Lease with respect to such Contemplated Transfer Space as of the Contemplated Effective Date, provided that Landlord shall separately demise the Contemplated Transfer Space, at Landlord’s cost, if Tenant would have entered into the Transfer without separately demising the Contemplated Transfer Space. In the event of a recapture by Landlord, if this Lease shall be canceled with respect to less than the entire Premises, the Rent reserved herein shall be prorated on the basis of the number of rentable square feet retained by Tenant in proportion to the number of rentable square feet contained in the Premi ses, and this Lease as so amended shall continue thereafter in full force and effect, and upon request of either party, the parties shall execute written confirmation of the same. If Landlord declines, or fails to elect in a timely manner, to recapture such Contemplated Transfer Space under this Section 11.02, then, subject to the other terms of this Section 11, for a period of 9 months (the “Nine Month Period”) commencing on the last day of such ten (10) Business Day period, then Tenant shall deliver a second notice requesting Landlord’s election and if Landlord thereafter fails to respond within five (5) Business Days, Landlord shall not have any right to recapture the Contemplated Transfer Space with respect to any applicable Transfer made during the Nine Month Period, provided that any such Transfer is substantially on the terms set forth in the Intention to Transfer Notice, and provided further that any such Transfer shall be subject to the remaining terms of this Section 11. If such a Transfer is not so consummated within the Nine Month Period (or if a Transfer is so consummated, then upon the expiration of the term of any Transfer of such Contemplated Transfer Space consummated within such Nine Month Period), Tenant shall again be required to submit a new Intention to Transfer Notice to Landlord with respect any contemplated Transfer, as provided above in this Section 11.02.

11.03 Except with respect to a Permitted Transfer or a Pre-Approved Transfer, Tenant shall pay Landlord 50% of any “Transfer Premium,” as that term is defined in this Section 11.03, actually received by Tenant from such transferee. “Transfer Premium” shall mean all rent, additional rent or other consideration which Tenant receives in connection with the Transfer, to the extent such rent and other consideration is attributable to a Transfer of Tenant’s interest in this Lease or the Premises (as opposed proceeds payable to Tenant in connection with the sale of Tenant’s business), in excess of the Rent and Additional Rent payable by Tenant under this Lease during the term of the Transfer on a per rentable square foot basis if less than all of the Premises is transferred; provided, however, that Tenant shall not be required to pay to Landlord a ny Transfer Premium until such time as Tenant has recovered all applicable “Subleasing Costs,” as that term is defined in this Section 11.03, it being understood that if in any year the gross revenues, less the deductions set forth and included in Subleasing Costs, are less than any and all costs actually paid in assigning or subletting the affected space (collectively “Transaction Costs”), the amount of the excess Transaction Costs shall be carried over to the next year and then deducted from net revenues with the procedure repeated until a Transfer Premium is achieved. There shall be deducted from

10

the Transfer Premium the reasonable expenses incurred by Tenant for (i) any changes, alterations and improvements to the Premises in connection with the Transfer, (ii) any free base rent reasonably provided to the transferee, (iii) any brokerage commissions in connection with the Transfer, (iv) any lease takeover incurred by Tenant in connection with the Transfer; (v) out-of-pocket costs of advertising the space subject to the Transfer, (vi) any improvement allowance or other economic concessions paid by Tenant to the transferee in connection with the Transfer; and (vii) reasonable attorneys’ fees incurred by Tenant in connection with the Transfer (collectively, “Subleasing Costs”). “Transfer Premium” shall also include, but not be limited to, key money, bonus money or other cash consideration paid by transferee to Tenant in connect ion with such Transfer, and any payment in excess of fair market value for services rendered by Tenant to transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to transferee in connection with such Transfer (but excluding any proceeds payable to Tenant in connection with a sale of its business). Tenant shall pay Landlord for Landlord’s share of any Transfer Premium within 30 days after Tenant’s receipt of the same. If Tenant is in Monetary Default (as defined in Section 18), Landlord may require that all sublease payments be made directly to Landlord, in which case Tenant shall receive a credit against Rent in the amount of Tenant’s share of payments received by Landlord.

11.04 Tenant may assign this Lease or sublease all or any portion of the Premises to a successor to Tenant by purchase, merger, consolidation or reorganization (an “Ownership Change”) or assign this Lease or sublet all or a portion of the Premises to an Affiliate without the consent of Landlord and without the payment of any Transfer Premium, provided that all of the following conditions are satisfied (a “Permitted Transfer”): (a) Tenant is not in Monetary Default under this Lease beyond any applicable notice and cure period provided in this Lease; (b) in the event of an Ownership Change, Tenant’s successor shall own substantially all of the stock or assets of Tenant and satisfy the Credit Requirement (defined below); (c) the Permitted Use does not allow the Premises to be used for retail purposes (i.e., sales to the public where the& #160; public comes to the Premises); and (d) Tenant shall give Landlord written notice at least 15 days prior to the effective date of the Permitted Transfer (provided that, if prohibited by confidentiality in connection with a proposed purchase, merger, consolidation or reorganization, then Tenant shall give Landlord written notice within 10 days after the effective date of the proposed purchase, merger, consolidation or reorganization). Tenant’s notice to Landlord shall include information and documentation evidencing the Permitted Transfer and showing that each of the above conditions has been satisfied. If requested by Landlord, Tenant’s successor shall sign a commercially reasonable form of assumption agreement. As used herein, “Affiliate” shall mean (i) an entity controlled by, controlling or under common control with Tenant; (ii) a purchaser or transferee of the assets or a majority of stock or membership interests of Tenant through a purchase, merger, c onsolidation or reorganization of Tenant by or with another entity (whether such acquisition takes the form of an asset sale, a stock sale or a combination thereof). “Control,” as used in this Section 11.04, shall mean the ownership, directly or indirectly, of at least 51% of the voting securities of, or possession of the right to vote, in the ordinary direction of its affairs, of at least 51% of the voting interest in, any person or entity. Notwithstanding anything to the contrary contained in this Section 11.04, “Permitted Transfer” shall also include (w) the issuance of stock in Tenant pursuant to an initial public offering, or (x) Tenant’s acquisition of other entities so long as Tenant’s financial strength immediately following such acquisition(s) is not less than that of Tenant as of the day prior to such acquisition(s). The “Credit Requirement” shall be deemed satisfied if, as of the date imme diately following the date of the Transfer, the financial strength of the entity with which Tenant is to merge or consolidate is not less than that of Tenant as of the day prior to the proposed Ownership Change, as determined (x) based on credit ratings of such entity and Tenant by both Moody’s and Standard & Poor’s (or by either such agency alone, if applicable ratings by the other agency do not exist), or (y) if such credit ratings do not exist, then in accordance with Moody’s KMV RiskCalc (i.e., the on-line software tool offered by Moody’s for analyzing credit risk) based on CFO-certified financial statements for such entity and Tenant covering their last two fiscal years ending before the Transfer.

11.05 Notwithstanding any contrary provision of this Section 11, Tenant shall have the right without the payment of a Transfer Premium and without the receipt of Landlord’s consent and without being subject to Landlord’s recapture right, but upon a minimum of 10 Business Days prior written notice to Landlord, to sublease up to 4,000 rentable square feet of the Premises (the “Pre-Approved Transfer”) to Helio LLC, a Delaware limited liability company (the “Pre-Approved Transferee”), on and subject to the following conditions: (i) such Pre-Approved Transferee shall not be permitted to occupy a separately demised portion of the Premises which contains an entrance to such portion of the Premises other than the primary entrance to the Premises; and (ii) such Pre-Approved Transfer shall not be a subterfuge by Tenant to avoid its ob ligations under this Lease or the restrictions on Transfers pursuant to this Section 11. Tenant shall promptly supply Landlord with any documents or information reasonably requested by Landlord regarding any such Pre-Approved Transfer. Any Pre-Approved Transfer permitted under this Section 11.05 shall not be deemed a Transfer under this Section 11. Notwithstanding the foregoing, no such Pre-Approved Transfer shall relieve Tenant from any liability under this Lease.

12. Liens.

Tenant shall not permit mechanics’ or other liens to be placed upon the Property, Premises or Tenant’s leasehold interest in connection with any work or service done or purportedly done by or for the benefit of Tenant or its transferees (and not by Landlord). Tenant shall give Landlord notice at least 10

11

days prior to the commencement of any work in the Premises to afford Landlord the opportunity, where applicable, to post and record notices of non-responsibility. Tenant, within 10 Business Days of notice from Landlord, shall fully discharge any lien by settlement, by bonding or by insuring over the lien in the manner prescribed by the applicable lien Law. If Tenant fails to do so, Landlord may bond, insure over or otherwise discharge the lien. Tenant shall reimburse Landlord for any amount paid by Landlord, including, without limitation, reasonable attorneys’ fees within 30 days after receipt of an invoice from Landlord.

13. Indemnity and Waiver of Claims.

13.01 Except to the extent caused by negligence or willful misconduct of Landlord or the Landlord Related Parties or a breach of this Lease by Landlord, and subject to the terms of Section 15, Tenant hereby waives all claims against and releases Landlord and its trustees, members, principals, beneficiaries, partners, officers, directors, employees, Mortgagees (defined in Section 23) and agents (the “Landlord Related Parties”) from all claims for any injury to or death of persons, damage to property or business loss in any manner related to (a) Force Majeure, (b) acts of third parties, (c) the bursting or leaking of any tank, water closet, drain or other pipe, (d) the inadequacy or failure of any security services, personnel or equipment, or (e) any matter not within the reasonable control of Landlord. Nothing herein shall be con strued as to diminish the repair and maintenance obligations of Landlord contained elsewhere in this Lease. Except to the extent caused by the negligence or willful misconduct of Landlord or any Landlord Related Parties or a breach of this Lease by Landlord, and subject to the terms of Section 15, Tenant shall indemnify, defend and hold Landlord and Landlord Related Parties harmless against and from all liabilities, obligations, damages, penalties, claims, actions, costs, charges and expenses, including, without limitation, reasonable attorneys’ fees and other professional fees (if and to the extent permitted by Law) (collectively referred to as “Losses”), which may be imposed upon, incurred by or asserted against Landlord or any of the Landlord Related Parties by any third party and arising out of or in connection with (i) any damage or injury occurring in the Premises, (ii) any negligent acts or omissions (including violations of Law) of Tenant, the Tenant Related Parti es or any of Tenant’s transferees, contractors or licensees in connection with such parties’ activities in the Premises or the Building or on the Property, (iii) the use by Tenant of the Premises for the Permitted Use, or (iv) the breach by Tenant of the terms and conditions of this Lease. Except to the extent caused by the negligence or willful misconduct of Tenant or any Tenant Related Parties or a breach of this Lease by Tenant, and subject to the terms of Section 15, Landlord shall indemnify, defend and hold Tenant, its trustees, members, principals, beneficiaries, partners, officers, directors, employees and agents (“Tenant Related Parties”) harmless against and from all Losses which may be imposed upon, incurred by or asserted against Tenant or any of the Tenant Related Parties by any third party and arising out of or in connection with the negligent acts or omissions (including violations of Law) of Landlord or the Landlord Related Parties or any of Land lord’s contractors or licensees in connection with such parties’ activities in the Building or on the Property or a breach of this Lease by Landlord, and subject to the terms of Section 15.

13.02 Notwithstanding anything to the contrary contained in this Lease, nothing in this Lease shall impose any obligations on Tenant or Landlord to be responsible or liable for, and each hereby releases the other from all liability for, consequential damages other than those consequential damages incurred by Landlord in connection with a holdover of the Premises by Tenant after the expiration or earlier termination of this Lease, or incurred by Landlord in connection with any repair, physical construction or improvement work performed by or on behalf of Tenant at the Building.

14. Insurance.

Tenant shall maintain the following insurance (“Tenant’s Insurance”): (a) Commercial General Liability Insurance/Excess Liability Insurance applicable to the Premises and its appurtenances providing, on an occurrence basis, a minimum combined single limit of $2,000,000.00; (b) Property/Extra Expense Insurance written on an All Risk or Special Perils form, with coverage for broad form water damage including earthquake sprinkler leakage, at replacement cost value and with a replacement cost endorsement covering all of Tenant’s business and trade fixtures, equipment, movable partitions, furniture, merchandise and other personal property within the Premises (“Tenant’s Property”) and any Leasehold Improvements performed by or for the benefit of Tenant; (c) Workers’ Compensation Insurance in amounts required by Law; and (d)& nbsp;Employers Liability Coverage of at least $1,000,000.00 per occurrence. Any company writing Tenant’s Insurance shall have an A.M. Best rating of not less than A-VIII. All Commercial General Liability Insurance policies shall name as additional insureds Landlord (or its successors and assignees), the managing agent for the Building (or any successor), EOP Operating Limited Partnership, Equity Office Properties Trust and their respective members, principals, beneficiaries, partners, officers, directors, employees, and agents, and other designees of Landlord and its successors. In addition, Landlord shall be named as a loss payee with respect to Property Insurance on the Leasehold Improvements (but not with respect to Tenant’s Property). All policies of Tenant’s Insurance shall contain endorsements that the insurer(s) shall endeavor to give Landlord and its designees at least 30 days’ advance written notice of any cancellation, termination, material change in covera ge which causes such coverage to be less than that required by this Lease or lapse of insurance.

12

Tenant shall provide Landlord with a certificate of insurance evidencing Tenant’s Insurance prior to the earlier to occur of the Commencement Date or the date Tenant is provided with possession of the Premises, and thereafter as necessary to assure that Landlord always has current certificates evidencing Tenant’s Insurance. Notwithstanding any contrary provision of this Section 14, Tenant may fulfill its insurance obligations under this Section 14 through a “blanket” insurance policy so long as such blanket insurance policy complies with the terms and conditions of this Section 14. Landlord shall carry commercial general liability insurance with respect to the Building during the Term, and shall further insure the Building during the Term (for the full replacement value to the extent consistent with the practices of landlords of the Comparable Buildings) against loss or damage due to fire and other casualties covered within the classification of fire and extended coverage, vandalism coverage and malicious mischief, sprinkler leakage, water damage and special extended coverage. Such coverage shall be in such amounts, from such companies, and on such other terms and conditions, as Landlord may from time to time reasonably determine. Additionally, at the option of Landlord, such insurance coverage may include the risks of earthquakes and/or flood damage, terrorist acts and additional hazards, a rental loss endorsement and one or more loss payee endorsements in favor of the holders of any mortgages or deeds of trust encumbering the interest of Landlord in the Building or the ground or underlying lessors of the Building, or any portion thereof. Notwithstanding the foregoing provisions of this Section 14, the coverage and amounts of insurance carried by Landlord in connection with the Building shall, at a minimum, be comparable to the coverage and amounts o f insurance which are carried by reasonably prudent landlords of Comparable Buildings (provided that in no event shall Landlord be required to carry earthquake insurance), and Worker’s Compensation and Employer’s Liability coverage as required by Law. Except as specifically provided to the contrary in this Lease, the limits of either party’s insurance shall not limit such party’s liability under this Lease. Notwithstanding anything to the contrary contained in this Lease, in the event of any termination of this Lease pursuant to Sections 16 or 17 below: (i) Tenant shall assign and deliver to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance on Leasehold Improvements required under Section 14 of this Lease for the lesser of (a) the unamortized value of the Initial Alterations (“Landlord’s TI Proceeds”), which such amortization to be calculated on a straight-line basis throughou t the initial Term and (b) $30.00 per rentable square feet of the Premises; and (ii) the remainder of any insurance proceeds received by Tenant under Section 14 shall be retained by Tenant.

15. Subrogation.

Notwithstanding anything to the contrary contained in this Lease, Landlord and Tenant hereby waive and shall cause their respective insurance carriers to waive any and all rights of recovery, claims, actions or causes of action against the other for any loss or damage with respect to Tenant’s Property, Leasehold Improvements, the Building, the Premises, the Property, any additions or improvements to the Building or the Property, or any contents thereof, including rights, claims, actions and causes of action based on negligence, which loss or damage is (or would have been, had the insurance required by this Lease been carried) covered by insurance.

16. Casualty Damage.

16.01 If all or any portion of the Premises becomes untenantable by fire or other casualty to the Premises (collectively a “Casualty”), or if all or any portion of the Building, including the Parking Facility, shall be made untenantable by fire or other casualty and Tenant’s use of or access to the Premises is materially interfered with as a result thereof, then Landlord shall, within 90 days following the date of the Casualty cause a licensed general contractor selected by Landlord to provide Landlord and Tenant with a written estimate of the amount of time required using standard working methods to substantially complete the repair and restoration of the Premises, any Common Areas necessary to provide access to the Premises and the Parking Facility (but only to the extent it materially impacts Tenant’s use of or access to the Premises) (“Complet ion Estimate”). If the Completion Estimate indicates that the Premises, any Common Areas necessary to provide access to the Premises or Parking Facility (but only to the extent it materially impacts Tenant’s use of or access to the Premises) cannot be made tenantable within 270 days from the date the repair is started, then either party shall have the right to terminate this Lease upon written notice to the other within 20 days after receipt of the Completion Estimate, in which event this Lease shall terminate 30 days thereafter. Further notwithstanding any contrary provision of this Section 16.01, in the event that the Premises, Common Areas (but only to the extent it materially impacts Tenant’s use of or access to the Premises) or Parking Facility (but only to the extent it materially impacts Tenant’s use of or access to the Premises) have been materially damaged and there is less than 1 year of the Term remaining on the date of the Casualty, then Tenant may elect to term inate this Lease by notifying Landlord in writing within 60 days after the date of the Casualty. In addition, Landlord, by notice to Tenant within 90 days after the date of the Casualty, shall have the right to terminate this Lease if: (1) the Premises, the Common Areas and the Parking Facility have been materially damaged and there is less than 1 year of the Term remaining on the date of the Casualty and Tenant has not exercised its option to extend hereunder; (2) any Mortgagee requires that the insurance proceeds in excess of the “Landlord Contribution,” as that term is defined below, be applied to the payment of the mortgage debt; or (3) the damage is not fully covered by Landlord’s insurance policies (or by the insurance Landlord is required to carry hereunder), the amount of such shortfall (including deductibles) exceeds 5% of the replacement cost

13

of the Building (“Landlord Contribution”), but with respect to this item 3, Landlord must also terminate all leases for space similarly affected by such loss. Notwithstanding the foregoing, if Tenant was entitled to but elected not to exercise its right to terminate the Lease and Landlord does not substantially complete the repair and restoration of the Premises, Building or Parking Facility, as the case may be (but in connection with the repair and restoration of the Building, only to the extent required so that Tenant’s use of and access to the Premises is no longer materially interfered with), within 2 months after the expiration of the estimated period of time set forth in the Completion Estimate, which period shall be extended to the extent of any Reconstruction Delays, then Tenant may terminate this Lease by written notice to Landlord within 30 days after the expiration of such period, as the same may be extended. For purposes of this Lease, the term “Reconstruction Delays” shall mean: (i) any delays caused by the insurance adjustment process (not to exceed 60 days in total); and (ii) any delays caused by Tenant.

16.02 If this Lease is not terminated, Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, restore the Premises, Base Building and Common Areas. Such restoration shall be to substantially the same condition that existed prior to the Casualty, except for modifications required by Law or any other modifications to the Common Areas deemed desirable by Landlord which are consistent with the character of the Property, provided that access to and use of the Premises and any common restrooms serving the Premises shall not be materially impaired. Upon notice from Landlord, subject to the provisions of Section 14 above, Tenant shall assign to Landlord (or to any party designated by Landlord) all property insurance proceeds payable to Tenant under Tenant’s Insurance with respect to any L easehold Improvements performed by or for the benefit of Tenant. Landlord shall not be liable for any inconvenience to Tenant, or injury to Tenant’s business resulting in any way from the Casualty or the repair thereof; provided however, that if such fire or other casualty shall have damaged the Premises or Common Areas necessary to Tenant’s occupancy, Landlord shall allow Tenant an abatement of Rent pursuant to the terms of Section 7.03 of this Lease (but the Eligibility Period shall not apply), provided that Tenant’s right to Rent abatement pursuant to the terms of this Section 16 shall terminate as of the date Tenant should have completed repairs to the Premises assuming Tenant used reasonable due diligence in connection therewith (provided that in no event shall such Rent re-commence until such time as Landlord has restored the Base Building to a commercially reasonable condition and Landlord has obtained whatever occupancy pe rmits that are required to allow the Building to be open and operating and to allow the Tenant to conduct business operations from its Premises (assuming that Tenant has received a certificate of occupancy, temporary certificate of occupancy, or its legal equivalent, for its Premises, which shall remain Tenant’s obligation)).

16.03 The provisions of this Lease, including this Section 16, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises or the Property, and any Laws, including, without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any other Laws now or hereinafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises or the Property.

17. Condemnation.

Either party may terminate this Lease if any material part of the Premises, or if all or a any portion of the Building which would materially interfere with Tenant’s use of or access to the Premises, is taken or condemned for any public or quasi-public use under Law, by eminent domain or private purchase in lieu thereof (a “Taking”). Landlord shall also have the right to terminate this Lease if there is a Taking of any portion of the Building or Property which would have a material adverse effect on Landlord’s ability to profitably operate the remainder of the Building, but Landlord may only terminate this Lease pursuant to this sentence to the extent that Landlord terminates the leases of all tenants similarly affected by the Taking. The terminating party shall provide written notice of termination to the other party within 45 days after it first receive s notice of the Taking. The termination shall be effective on the date the physical taking occurs. If this Lease is not terminated, Base Rent and Tenant’s Pro Rata Share shall be appropriately adjusted to account for any reduction in the square footage of the Building or Premises. All compensation awarded for a Taking shall be the property of Landlord, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s Property, and for moving expenses, so long as such claim is payable separate to Tenant or is otherwise separately identifiable. Subject to the foregoing, the right to receive compensation or proceeds are expressly waived by Tenant. If only a part of the Premises is subject to a Taking and this Lease is not terminated, Landlord, with reasonable diligence, will restore the remaining portion of the Premises as nearly as practicable to the condition immediately prior to the Taking. Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of the California Code of Civil Procedure, or any similar or successor Laws.

18. Events of Default.

Each of the following occurrences shall be a “Default”: (a) Tenant’s failure to pay any portion of Rent

14

when due, if the failure continues for five (5) Business Days after written notice to Tenant (“Monetary Default”); (b) Tenant’s failure (other than a Monetary Default) to comply with any term, provision, condition or covenant of this Lease, if the failure is not cured within thirty (30) days after written notice to Tenant provided, however, if Tenant’s failure to comply cannot reasonably be cured within thirty (30) days, Tenant shall be allowed additional time as is reasonably necessary to cure the failure so long as Tenant begins the cure within thirty (30) days and diligently pursues the cure to completion; (c) Tenant or any Guarantor becomes insolvent, makes a transfer in fraud of creditors, makes an assignment for the benefit of creditors, admits in writing its inability to pay its debts when due or forfeits or loses its right to conduct business; (d) the lease hold estate is taken by process or operation of Law; (e) Tenant’s failure to observe or perform according to the provisions of Articles 5, 11 and 23 of this Lease where such failure continues for more than an additional five (5) Business Days after notice from Landlord; provided, however, if Tenant’s failure to comply cannot reasonably be cured within such five (5) Business Day period, Tenant shall be allowed additional time as is reasonably necessary to cure the failure so long as Tenant begins the cure within five (5) Business Days and diligently pursues the cure to completion; or (f) Tenant is in default beyond any notice and cure period under any other lease or agreement with Landlord affecting the Building or Property, including, without limitation, any lease or agreement for parking. All notices sent under this Section 18 shall be in satisfaction of, and not in addition to, notice required by Law.

19. Remedies.

19.01 Upon the occurrence of any Default under this Lease, whether enumerated in Section 18 or not, Landlord shall have the option to pursue any one or more of the following remedies without any notice (except as expressly prescribed herein) or demand whatsoever (and without limiting the generality of the foregoing, Tenant hereby specifically waives notice and demand for payment of Rent or other obligations, except for those notices specifically required pursuant to the terms of Section 18 or this Section 19 or elsewhere in this Lease and waives any and all other notices or demand requirements imposed by applicable law):

(a) Terminate this Lease and Tenant’s right to possession of the Premises and recover from Tenant an award of damages equal to the sum of the following:

(i) The Worth at the Time of 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 which would have been earned after termination until the time of award exceeds the amount of such Rent loss that Tenant affirmatively proves could have been reasonably avoided;

(iii) The Worth at the Time of Award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds the amount of such Rent loss that Tenant affirmatively proves could be reasonably avoided;

(iv) Any other amount necessary to compensate Landlord for all the detriment either 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; and

(v) All such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time under applicable law.

The “Worth at the Time of Award” of the amounts referred to in parts (i) and (ii) above, shall be computed by allowing interest at the lesser of a per annum rate equal to: (A) the greatest per annum rate of interest permitted from time to time under applicable law, or (B) the Prime Rate plus 2%. For purposes hereof, the “Prime Rate” shall be the per annum interest rate publicly announced as its prime or base rate by a federally insured bank selected by Landlord in the State of California. The “Worth at the Time of Award” of the amount referred to in part (iii), above, shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus 1%;

(b) Employ the remedy described in California Civil Code § 1951.4 (Landlord may continue this Lease in effect after Tenant’s breach and abandonment and recover Rent as it becomes due, if Tenant has the right to sublet or assign, subject only to reasonable limitations); or

(c) Notwithstanding Landlord’s exercise of the remedy described in California Civil Code § 1951.4 in respect of an event or events of default, at such time thereafter as Landlord

15

may elect in writing, to terminate this Lease and Tenant’s right to possession of the Premises and recover an award of damages as provided above in Paragraph 19.01(a).

19.02 The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the particular Rent so accepted, regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such Rent. No waiver by Landlord of any breach hereof shall be effective unless such waiver is in writing and signed by Landlord.

19.03 TENANT HEREBY WAIVES ANY AND ALL RIGHTS CONFERRED BY SECTION 3275 OF THE CIVIL CODE OF CALIFORNIA AND BY SECTIONS 1174 (c) AND 1179 OF THE CODE OF CIVIL PROCEDURE OF CALIFORNIA AND ANY AND ALL OTHER LAWS AND RULES OF LAW FROM TIME TO TIME IN EFFECT DURING THE LEASE TERM OR THEREAFTER PROVIDING THAT TENANT SHALL HAVE ANY RIGHT TO REDEEM, REINSTATE OR RESTORE THIS LEASE FOLLOWING ITS TERMINATION BY REASON OF TENANT’S BREACH.

THE PARTIES HEREBY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, THE RIGHT TO TRIAL BY JURY IN ANY LITIGATION ARISING OUT OF OR RELATING TO THIS LEASE. IF THE JURY WAIVER PROVISIONS OF THIS SECTION 19.03 ARE NOT ENFORCEABLE UNDER CALIFORNIA LAW, THEN THE FOLLOWING PROVISIONS SHALL APPLY. It is the desire and intention of the parties to agree upon a mechanism and procedure under which controversies and disputes arising out of this Lease or related to the Premises will be resolved in a prompt and expeditious manner. Accordingly, except with respect to actions for unlawful or forcible detainer or with respect to the prejudgment remedy of attachment, any action, proceeding or counterclaim brought by either party hereto against the other (and/or against its officers, directors, employees, agents or subsidiaries or affiliated entities) on any matters whatsoever arising out of or in any way connected with this Lease, Tenant’s use or occupancy of the Premises and/or any claim of injury or damage, whether sounding in contract, tort, or otherwise, shall be heard and resolved by a referee under the provisions of the California Code of Civil Procedure, Sections 638 — 645.1, inclusive (as same may be amended, or any successor statute(s) thereto) (the “Referee Sections”). Any fee to initiate the judicial reference proceedings and all fees charged and costs incurred by the referee shall be paid by the party initiating such procedure (except that if a reporter is requested by either party, then a reporter shall be present at all proceedings where requested and the fees of such reporter — except for copies ordered by the other parties — shall be borne by the party requesting the reporter); provided however, that allocation of the costs and fees, including any initiation fee, of such proceeding shall be ultimately determined in accordance with Section 26.02 below. The venue of the proceedings shall be in the county in which the Premises are located. Within 10 days of receipt by any party of a written request to resolve any dispute or controversy pursuant to this Section 19.03, the parties shall agree upon a single referee who shall try all issues, whether of fact or law, and report a finding and judgment on such issues as required by the Referee Sections. If the parties are unable to agree upon a referee within such 10 day period, then any party may thereafter file a lawsuit in the county in which the Premises are located for the purpose of appointment of a referee under the Referee Sections. If the referee is appointed by the court, the referee shall be a neutral and impartial retired judge with substantial experience in the relevant matters to be determined, from Jams/Endispute, Inc., the American Arbitration Association or similar mediation/arbitration entity. The proposed referee may be challenged by any party for any of the grounds listed in the Referee Sections. The referee shall have the power to decide all issues of fact and law and report his or her decision on such issues, and to issue all recognized remedies available at Law or in equity for any cause of action that is before the referee, including an award of attorneys’ fees and costs in accordance with this Lease. The referee shall not, however, have the power to award punitive damages, nor any other damages which are not permitted by the express provisions of this Lease, and the parties hereby waive any right to recover any such damages. The parties shall be entitled to conduct all discovery as provided in the California Code of Civil Procedure, and the referee shall oversee discovery and may enforce all discovery orders in the same manner as any trial court judge, with rights to regulate discovery and to issue and enforce subpoenas, protective orders and other limitations on discovery available under California law. The reference proceeding shall be conducted in accordance with California law (including the rules of evidence), and in all regards, the referee shall follow California law applicable at the time of the reference proceeding. The parties shall promptly and diligently cooperate with one another and the referee, and shall perform such acts as may be necessary to obtain a prompt and expeditious resolution of the dispute or controversy in accordance with the terms of this Section 19.03. In this regard, the parties agree that the parties and the referee shall use best efforts to ensure that (a) discovery be conducted for a period no longer than 6 months from the date the referee is appointed, excluding motions regarding discovery, and (b) a trial date be set within 9 months of the date the referee is appointed. In accordance with Section 644 of the California Code of Civil Procedure, the decision of the referee upon the whole issue must stand as the decision of the court, and up on the filing of the statement of decision with the clerk of the court, or with the judge if there is no clerk, judgment may be entered thereon in the same manner as if the action had been tried by the court. Any decision of the referee and/or judgment or other order entered thereon shall be appealable to the same extent and in the same manner that such decision, judgment, or order would be appealable if rendered by a judge of the superior court in which venue is proper hereunder. The referee shall in his/her statement of decision set forth his/her findings of fact and conclusions of law. The parties intend this general reference agreement to be specifically enforceable in

16

accordance with the Code of Civil Procedure. Nothing in this Section 19.03 shall prejudice the right of any party to obtain provisional relief or other equitable remedies from a court of competent jurisdiction as shall otherwise be available under the Code of Civil Procedure and/or applicable court rules.

19.04 No right or remedy herein conferred upon or reserved to Landlord or Tenant is intended to be exclusive of any other right or remedy, and each and every right and remedy shall be cumulative and in addition to any other right or remedy given hereunder or now or hereafter existing by agreement, applicable law or in equity. In addition to other remedies provided in this Lease, Landlord and Tenant shall be entitled, to the extent permitted by applicable law, to injunctive relief, or to a decree compelling performance of any of the covenants, agreements, conditions or provisions of this Lease, or to any other remedy allowed to Landlord or Tenant at law or in equity. Forbearance by Landlord or Tenant to enforce one or more of the remedies herein provided upon an event of default shall not be deemed or construed to constitute a waiver of such default.

19.05 This Section 19 shall be enforceable to the maximum extent such enforcement is not prohibited by applicable law, and the unenforceability of any portion thereof shall not thereby render unenforceable any other portion.

20. Limitation of Liability.

NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS LEASE, THE LIABILITY OF LANDLORD (AND OF ANY SUCCESSOR LANDLORD) SHALL BE LIMITED TO THE INTEREST OF LANDLORD IN THE PROPERTY. TENANT SHALL LOOK SOLELY TO LANDLORD’S INTEREST IN THE PROPERTY FOR THE RECOVERY OF ANY JUDGMENT OR AWARD AGAINST LANDLORD OR ANY LANDLORD RELATED PARTY. NEITHER LANDLORD NOR ANY LANDLORD RELATED PARTY SHALL BE PERSONALLY LIABLE FOR ANY JUDGMENT OR DEFICIENCY, AND IN NO EVENT SHALL LANDLORD OR ANY LANDLORD RELATED PARTY BE LIABLE TO TENANT FOR ANY LOST PROFIT, DAMAGE TO OR LOSS OF BUSINESS OR ANY FORM OF SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGE. BEFORE FILING SUIT TO TERMINATE THIS LEASE FOR AN ALLEGED DEFAULT BY LANDLORD, TENANT SHALL GIVE LANDLORD AND THE MORTGAGEE(S) WHOM TENANT HAS BEEN NOTIFIED HOLD MORTGAGES (DEFINED IN SECTION 23 BELOW), NOTICE AND REASONABLE TIME TO CURE THE ALLEGED DEF AULT. FOR PURPOSES HEREOF, “INTEREST OF LANDLORD IN THE PROPERTY” SHALL INCLUDE RENTS DUE FROM TENANTS, INSURANCE PROCEEDS, SALES PROCEEDS AND PROCEEDS FROM CONDEMNATION OR EMINENT DOMAIN PROCEEDINGS (PRIOR TO THE DISTRIBUTION OF SAME TO ANY PARTNER OR SHAREHOLDER OF LANDLORD OR ANY OTHER THIRD PARTY).

21. Relocation.

INTENTIONALLY OMITTED.

22. Holding Over.

Except for any permitted occupancy by Tenant under Section 8 above, if Tenant fails to surrender all or any part of the Premises at the termination of this Lease, occupancy of the Premises after termination shall be that of a tenancy at sufferance. Tenant’s occupancy shall be subject to all the terms and provisions of this Lease, and Tenant shall pay an amount equal to, (i) for the first thirty (30) days of such holdover, 125% of the sum of the Base Rent due for the period immediately preceding the holdover, and (ii) thereafter, 150% of the sum of the Base Rent due for the period immediately preceding the holdover. No holdover by Tenant or payment by Tenant after the termination of this Lease shall be construed to extend the Term or prevent Landlord from immediate recovery of possession of the Premises by summary proceedings or otherwise. If Landlord is unable to deli ver possession of the Premises to a new tenant or to perform improvements for a new tenant as a result of Tenant’s holdover and Tenant fails to vacate the Premises within 30 days after notice from Landlord, Tenant shall be liable for all damages that Landlord suffers from the holdover.

23. Subordination to Mortgages; Estoppel Certificate.

23.01 Subject to Tenant’s receipt of the NDA (as defined in Section 23.03 below), Tenant accepts this Lease subject and subordinate to any mortgage(s), deed(s) of trust, ground lease(s) or other lien(s) now or subsequently arising upon the Premises, the Building or the Property, and to renewals, modifications, refinancings and extensions thereof (collectively referred to as a “Mortgage”). The party having the benefit of a Mortgage shall be referred to as a “Mortgagee”. This clause shall be self-operative, but upon request from a Mortgagee, Tenant shall execute a commercially reasonable subordination agreement in favor of the Mortgagee. As an alternative, a Mortgagee shall have the right at any time to subordinate its Mortgage to this Lease. Upon request, Tenant, without charge, shall attorn to any successor to Landlord’ ;s interest in this Lease. Landlord and Tenant shall each, within 10 Business Days after receipt of a written request from the other, execute and deliver a commercially reasonable estoppel certificate to those parties as are reasonably requested by the other (including a

17

Mortgagee or prospective purchaser). Without limitation, such estoppel certificate may include a certification as to the status of this Lease to the representing party’s actual knowledge as of the existence of any defaults and the amount of Rent that is due and payable.

23.02 Notwithstanding the foregoing, upon written request by Tenant, Landlord will use reasonable efforts to obtain a non-disturbance, subordination and attornment agreement from Landlord’s then current Mortgagee (other than the Mortgagee existing on the date of this Lease) on such Mortgagee’s then current standard form of agreement. “Reasonable efforts” of Landlord shall not require Landlord to incur any cost, expense or liability to obtain such agreement, it being agreed that Tenant shall be responsible for any fee or review costs charged by the Mortgagee. Upon request of Landlord, Tenant will execute the Mortgagee’s form of non-disturbance, subordination and attornment agreement and return the same to Landlord for execution by the Mortgagee. Landlord’s failure to obtain a non-disturbance, subordination and attornment agreement for Tenant shall have no effect on the rights, obligations and liabilities of Landlord and Tenant or be considered to be a default by Landlord hereunder.

23.03 Landlord hereby represents that there is, as of the date hereof other than a leasehold as created by that certain lease, executed by Pacific Lighting Properties, Inc., as Lessor and Tishman Westwood Corporation, as Lessee, as referenced in the document entitled “Memorandum of Lease”, which was recorded March 25, 1968 as Instrument No. 2898 in Book M-2809 Page 475, for the term and upon and subject to all the provisions contained in said document, in said lease, and in all amendments thereto, as Parcel 2, there are no ground or underlying leases covering the whole or any portion of the Property. Within five (5) Business Days following the full execution and delivery of this Lease by Landlord and Tenant, Landlord shall cause the fee owner of the Property to provide a commercially reasonable recognition, non-disturbance and attornment agreement in fa vor of Tenant in the form attached hereto as Exhibit M attached hereto (the “NDA”) and deliver the same to Tenant.

24. Notice.

All demands, approvals, consents or notices (collectively referred to as a “notice”) shall be in writing and delivered by hand or sent by registered or certified mail with return receipt requested or sent by overnight or same day courier service at the party’s respective Notice Address(es) set forth in Section 1. Each notice shall be deemed to have been received on the earlier to occur of actual delivery or the date on which delivery is refused, or, if Tenant has vacated the Premises or any other Notice Address of Tenant without providing a new Notice Address, 3 days after notice is deposited in the U.S. mail or with a courier service in the manner described above. If Landlord has vacated its Notice Address without providing Tenant a new Notice Address, Tenant may serve notice in any manner described in this Section or in any other manner permitted by Law. Either party may, at any time, change its Notice Address (other than to a post office box address) by giving the other party written notice of the new address.

25. Surrender of Premises.

At the termination of this Lease or Tenant’s right of possession, Tenant shall remove Tenant’s Property from the Premises, and quit and surrender the Premises to Landlord, broom clean, and in good order, condition and repair, ordinary wear and tear and damage which Landlord is obligated to repair hereunder excepted. If Tenant fails to remove any of Tenant’s Property within 2 days after termination of this Lease or Tenant’s right to possession, Landlord, at Tenant’s sole cost and expense, shall be entitled (but not obligated) to remove and store Tenant’s Property. Landlord shall not be responsible for the value, preservation or safekeeping of Tenant’s Property, except to the extent required by applicable Law. Tenant shall pay Landlord, upon demand, the expenses and storage charges incurred. If Tenant fails to remove Tenant’s Property from the Premises or storage, within 30 days after notice, Landlord may deem all or any part of Tenant’s Property to be abandoned and title to Tenant’s Property shall vest in Landlord.

26. Miscellaneous.

26.01 This Lease shall be interpreted and enforced in accordance with the Laws of the State of California and Landlord and Tenant hereby irrevocably consent to the jurisdiction and proper venue of such state or commonwealth. If any term or provision of this Lease shall to any extent be void or unenforceable, the remainder of this Lease shall not be affected. If there is more than one Tenant or if Tenant is comprised of more than one party or entity, the obligations imposed upon Tenant shall be joint and several obligations of all the parties and entities, and requests or demands from any one person or entity comprising Tenant shall be deemed to have been made by all such persons or entities. Notices to any one person or entity shall be deemed to have been given to all persons and entities. Tenant represents and warrants to Landlord that each individual executing this Lease on behalf of Tenant is authorized to do so on behalf of Tenant and that Tenant is not, and the entities or individuals constituting Tenant or which may own or control Tenant or which may be owned or controlled by Tenant are not, among the individuals or entities identified on any list compiled pursuant to Executive Order 13224 for the purpose of identifying suspected terrorists.

18

26.02 If either party institutes a suit against the other for violation of or to enforce any covenant, term or condition of this Lease, the prevailing party shall be entitled to all of its costs and expenses, including, without limitation, reasonable attorneys’ fees. Either party’s failure to declare a default immediately upon its occurrence, or delay in taking action for a default, shall not constitute a waiver of the default, nor shall it constitute an estoppel.

26.03 Whenever a period of time is prescribed for the taking of an action by Landlord or Tenant (other than the payment of the Security Deposit or Rent or other sums payable by either party), the period of time for the performance of such action shall be extended by the number of days that the performance is actually delayed due to strikes, acts of God, shortages of labor or materials, war, terrorist acts, civil disturbances and other causes beyond the reasonable control of the performing party (“Force Majeure”).

26.04 Landlord shall have the right to transfer and assign, in whole or in part, all of its rights and obligations under this Lease and in the Building and Property which thereafter arise, so long as such obligations are assumed in writing by Landlord’s successor in interest. Upon transfer Landlord shall be released from any further obligations thereafter arising hereunder and Tenant agrees to look solely to the successor in interest of Landlord for the performance of such obligations, provided that, any successor pursuant to a voluntary, third party transfer (but not as part of an involuntary transfer resulting from a foreclosure or deed in lieu thereof) shall have assumed Landlord’s obligations under this Lease, and further provided that Landlord and its successors, as the case may be, shall remain liable after their respective periods of ownership with respect to any s ums due in connection with a breach or default by such party that arose during such period of ownership by such party.

26.05 Landlord has delivered a copy of this Lease to Tenant for Tenant’s review only and the delivery of it does not constitute an offer to Tenant or an option. Tenant represents that it has dealt directly with and only with the Broker as a broker in connection with this Lease. Tenant shall indemnify and hold Landlord and the Landlord Related Parties harmless from all claims of any other brokers claiming to have represented Tenant in connection with this Lease. Landlord shall indemnify and hold Tenant and the Tenant Related Parties harmless from all claims of any brokers claiming to have represented Landlord in connection with this Lease. Equity Office Properties Management Corp. (“EOPMC”) is an affiliate of Landlord and represents only the Landlord in this transaction. Any assistance rendered by any agent or employee of EOPMC in connection with th is Lease or any subsequent amendment or modification hereto has been or will be made as an accommodation to Tenant solely in furtherance of consummating the transaction on behalf of Landlord, and not as agent for Tenant.

26.06 Time is of the essence with respect to Tenant’s exercise of any expansion, renewal or extension rights granted to Tenant. The expiration of the Term, whether by lapse of time, termination or otherwise, shall not relieve either party of any obligations which accrued prior to or which may continue to accrue after the expiration or termination of this Lease.

26.07 Tenant may peacefully and quietly have, hold and enjoy the Premises, subject to the terms of this Lease without interference by Landlord or any persons lawfully claiming by or through Landlord, provided Tenant pays the Rent and fully performs all of its covenants and agreements within the applicable cure periods in this Lease. This covenant shall be binding upon Landlord and its successors only during its or their respective periods of ownership of the Building. Landlord shall take commercially reasonable steps to provide for such quiet enjoyment, including without limitation, enforcing leases of adjacent tenants of the Building to the extent that such leases are being breached and such breach impacts on the quiet enjoyment of Tenant; provided, however, notwithstanding the foregoing, Landlord shall not have any obligation to commence litigation against such adjacent tenants u nless and to the extent that, given the nature and scope of such breach and the cost associated with the commencement and pursuit of such litigation, the same would be deemed commercially reasonable by a majority of landlords of Comparable Buildings.

26.08 This Lease does not grant any rights to light or air over or about the Building. Landlord excepts and reserves exclusively to itself any and all rights not specifically granted to Tenant under this Lease. This Lease constitutes the entire agreement between the parties and supersedes all prior agreements and understandings related to the Premises, including all lease proposals, letters of intent and other documents. Neither party is relying upon any warranty, statement or representation not contained in this Lease. This Lease may be modified only by a written agreement signed by an authorized representative of Landlord and Tenant. Notwithstanding the foregoing, but subject to Section 9.03 above, Tenant shall have the right to use the telephone, electrical and janitorial closets, and to access the space above the ceiling, under the floor and within the walls of the P remises.

26.09 Landlord Default. Notwithstanding anything to the contrary set forth in this Lease, Landlord shall be in Default in the performance of any obligation required to be performed by Landlord pursuant to this Lease if Landlord fails to perform such obligation within 30 days after the receipt of notice from Tenant

19

specifying in detail Landlord’s failure to perform; provided, however, if the nature of Landlord’s obligation is such that more than 30 days are required for its performance, then Landlord shall not be in Default under this Lease if it shall commence such performance within such 30 day period and thereafter diligently pursue the same to completion; provided, further, however, if Landlord’s failure to perform an obligation results in a failure of essential services to the Premises or Building, the terms of Section 7.03 shall apply and Landlord shall use commercially reasonable efforts to satisfy such obligation as soon as thereafter as reasonably practicable. Upon any such Default by Landlord under this Lease, Tenant may, except as otherwise specifically provided in this Lease to the contrary, exercise any of its rights provided at law or in equity. No right or remedy herein conferred u pon or reserved to Tenant is intended to be exclusive of any other right or remedy, and each and every right and remedy shall be cumulative and in addition to any other right or remedy given hereunder or now or hereafter existing by agreement, applicable law or in equity. In addition to other remedies provided in this Lease, Tenant shall be entitled, to the extent permitted by applicable law, to injunctive relief, or to a decree compelling performance of any of the covenants, agreements, conditions or provisions of this Lease, or to any other remedy allowed to Tenant at law or in equity. Forbearance by Tenant to enforce one or more of the remedies herein provided upon an event of Default shall not be deemed or construed to constitute a waiver of such Default.

26.10 Tenant shall have the right, at Tenant’s expense, to 5 lines on the directory board in the main lobby of the Building, to display Tenant’s name or the name of any transferee permitted or approved pursuant to the terms of Section 11 above and the names of their principal employees.

26.11 Tenant shall have the right, at Tenant’s expense subject to the Allowance, to signage in the elevator lobby on the 8 th floor of the Building. Tenant shall submit detailed drawings of its proposed signage to Landlord for its review and approval, which Landlord shall not unreasonably withhold, delay or condition. Such signage shall be available to any transferee permitted or approved pursuant to the terms of Section 11 above.

EXPENSES AND TAXES

This Exhibit is attached to and made a part of the Lease by and between CA-10960 WILSHIRE LIMITED PARTNERSHIP, a Delaware limited partnership (“Landlord”) and BOINGO WIRELESS, INC., a Delaware corporation (“Tenant”) for space in the Building located at 10960 Wilshire Boulevard, Los Angeles, California.

1. Payments.

1.01 Tenant shall pay Tenant’s Pro Rata Share of the amount, if any, by which Expenses (defined below) for each calendar year during the Term exceed Expenses for the Base Year (the “Expense Excess”) and also the amount, if any, by which Taxes (defined below) for each calendar year during the Term exceed Taxes for the Base Year (the “Tax Excess”). If Expenses or Taxes in any calendar year decrease below the amount of Expenses or Taxes for the Base Year, Tenant’s Pro Rata Share of Expenses or Taxes, as the case may be, for that calendar year shall be $0. Landlord shall provide Tenant with a statement (the “Estimate Statement”) which shall, on a line-item by line-item basis, set forth Landlord’s reasonable, good faith estimate of the Expense Excess and of the Tax Excess for each calendar year during the Term. ; Landlord shall endeavor to provide such Estimate Statement to Tenant on or before April 1 of each then-current calendar year, provided that Landlord’s failure to timely furnish the Estimate Statement for any calendar year shall not preclude Landlord from enforcing its rights to collect any Expense Excess or Tax Excess under this Exhibit B. On or before the first day of each month, Tenant shall pay to Landlord a monthly installment equal to one-twelfth of Tenant’s Pro Rata Share of Landlord’s estimate of both the Expense Excess and Tax Excess. After its receipt of a revised Estimate Statement, Tenant’s monthly payments shall be based upon the revised Estimate Statement. If Landlord does not provide Tenant with an Estimate Statement of the Expense Excess or the Tax Excess by January 1 of a calendar year, Tenant shall continue to pay monthly installments based on the previous year’s Estimate Statement until Landlord provides Tenant with the new Estima te Statement. Thereafter, Tenant shall pay, within thirty (30) days, a fraction of the new Estimate Statement for the then-current calendar year (reduced by any amounts paid pursuant to the preceding sentence of this Section 1.01). Such fraction shall have as its numerator the number of months which have elapsed in such current calendar year, including the month of such payment, and 12 as its denominator. Any overpayment shall be refunded to Tenant within thirty (30) days of Tenant’s receipt of such new Estimate Statement or credited against the next due future installment(s) of Rent.

1.02 Landlord shall use commercially reasonable efforts, within one hundred fifty (150) days following the end of each calendar year, to furnish Tenant with a statement (the “Statement”) of the actual Expenses and Expense Excess and the actual Taxes and Tax Excess for the prior calendar year. If the estimated Expense Excess or estimated Tax Excess for the prior calendar year is more than the actual Expense Excess or actual Tax Excess, as the case may be, for the prior calendar year, Landlord shall either provide Tenant with a refund or apply any overpayment by Tenant against Rent due or next becoming due, provided if the Term expires before the determination of the overpayment, Landlord shall refund any overpayment to Tenant after first deducting the amount of any Rent then due and payable by Tenant. If the estimated Expense Excess or estimated Tax Exces s for the prior calendar year is less than the actual Expense Excess or actual Tax Excess, as the case may be, for such prior year, Tenant shall pay Landlord, within thirty (30) days after its receipt of the Statement of Expenses or Taxes, any underpayment for the prior calendar year. Without limitation on other obligations of Tenant and Landlord which shall survive the expiration of the Term, the obligations of Tenant to pay the Additional Rent and the obligations of Landlord to refund any excess payments of Additional Rent, as provided for in this Section 1.02. shall survive the expiration of the Term to the extent such amounts are attributable to the Term. Notwithstanding the immediately preceding sentence, Tenant shall not be responsible for Tenant’s Pro Rata Share of any Expenses or Taxes attributable to any calendar year which are first billed to Tenant more than two (2) calendar years after the earlier of the expiration of the applicable calendar year or the Termination Date, prov ided that in any event Tenant shall be responsible for Tenant’s Pro Rata Share of Expenses and Taxes levied by any governmental authority or by any public utility companies at any time following the Termination Date which are attributable to any calendar year (provided that Landlord delivers Tenant a bill (a “Supplemental Statement”) for such amounts within two (2) years following Landlord’s receipt of the bill therefor).

The cost of the Capital Items shall be amortized by Landlord over the reasonable useful life of the Capital Item. The amortized cost of Capital Items may, at Landlord’s option, include actual or imputed interest at the Interest Rate. Landlord, by itself or through an affiliate, shall have the right to directly perform, provide and be compensated for any services under this Lease.

Subject to Landlord’s right to adjust the variable components of Expenses as set forth below in this Section, Landlord shall not collect Expenses from Tenant and all other tenants in the Building in an amount in excess of what Landlord incurred for the items included in Expenses.

2.03 If at any time during the Base Year or any subsequent calendar year during the Term, the Building is not at least 95% occupied or Landlord is not supplying services to at least 95% of the total Rentable Square Footage of the Building, then the variable components of Expenses for the Base Year or any such calendar year which vary based on occupancy levels of the Building shall be determined as if the Building had been 95% occupied and Landlord had been supplying services to 95% of the Rentable Square Footage of the Building. Notwithstanding the foregoing, Landlord may calculate the extrapolation of Expenses under this Section based on 100% occupancy and service so long as such percentage is used consistently for each calendar year of the Term (including the Base Year). The extrapolation of Expenses under this Section shall be performed in accordance with the methodology spe cified by the Building Owners and Managers Association.

3. “Taxes” shall mean: (a) all real property taxes and other assessments on the Building and/or Property, including, but not limited to, gross receipts taxes, assessments for special improvement districts and building improvement districts, governmental charges, fees and assessments for police, fire, traffic mitigation or other governmental service of purported benefit to the Property, taxes and assessments levied in substitution or supplementation in whole or in part of any such taxes and

4

assessments and the Property’s share of any real estate taxes and assessments under any reciprocal easement agreement, common area agreement or similar agreement as to the Property; (b) all personal property taxes for property that is owned by Landlord and used in connection with the operation, maintenance and repair of the Property; and (c) all reasonable costs and fees incurred in connection with seeking reductions in any tax liabilities described in (a) and (b), including, without limitation, any reasonable costs incurred by Landlord for compliance, review and appeal of tax liabilities (but specifically excluding (A) any costs incurred by Landlord in connection with any Proposition 8 reduction pursued by Landlord and (B) any assessments on improvements in other tenants’ premises at the Property to the extent that the assessed valuation of such improvements exceeds $30.00 pe r rentable square foot of the applicable tenant’s premises). Without limitation, Taxes shall not include any excess profits taxes, franchise taxes, succession taxes, federal and state income taxes, and other taxes to the extent applicable to Landlord’s general or net income (as opposed to rents, receipts or income attributable to operations at the Property), or any capital levy, transfer, capital stock, gift, estate or inheritance tax, or any items included as Expenses. All assessments and premiums which are not specifically charged to Tenant because of what Tenant has done, which can be paid by Landlord in installments, shall be paid by Landlord in the maximum number of installments permitted by Law (except to the extent inconsistent with the general practice of the “Comparable Buildings” (as defined in Section 1.17 of the Lease) and shall be included in Taxes in the year in which the assessment or premium installment is actually paid. If a change in Taxes is obtained fo r any calendar year of the Term during which Tenant paid Tenant’s Pro Rata Share of any Tax Excess, then Taxes for that year will be retroactively adjusted and Landlord shall provide Tenant with a credit, if any, based on the adjustment. Likewise, if a change is obtained for Taxes for the Base Year, Taxes for the Base Year shall be restated and the Tax Excess for all subsequent years shall be recomputed; provided, however, to the extent Taxes are reassessed as a result of the sale of Equity Office Properties Trust and its affiliates to Blackstone and its affiliates in February 2007), Taxes for the Base Year shall be grossed up to assume that such sale occurred on January 1, 2007. Tenant shall pay Landlord the amount of Tenant’s Pro Rata Share of any such increase in the Tax Excess within thirty (30) days after Tenant’s receipt of a statement from Landlord. Any overpayment by Tenant shall be refunded to Tenant within thirty (30) days or credited against the next due future installment(s) of Rent. Without limitation on other obligations of Tenant and Landlord which shall survive the expiration of the Term, the obligations of Tenant to pay Tenant’s Pro Rata Share of any such increase in the Tax Excess and the obligations of Landlord to refund to Tenant any overpayment by Tenant, as provided in Section 3, shall survive the expiration of the Term to the extent such amounts are attributable to the Term. For purposes of this Lease, Taxes shall be calculated as if the tenant improvements in the Building were fully constructed and the Property, the Building, and all tenant improvements in the Building were fully assessed for real estate tax purposes in every calendar year (including the Base Year) and the Taxes shall be deemed to be increased accordingly.

Notwithstanding anything to the contrary set forth in the Lease or this Exhibit B, the amount of Taxes for the Base Year and any subsequent calendar year shall be calculated without taking into account any decreases in real estate taxes obtained in connection with Proposition 8, and, therefore, the Taxes in the Base Year and/or a subsequent calendar year may be greater than those actually incurred by Landlord, but shall, nonetheless, be the Taxes due under this Lease; provided that (i) any reasonable costs and expenses incurred by Landlord in securing any Proposition 8 reduction shall not be included in or deducted from Taxes nor included in Expenses for purposes of this Lease, and (ii) tax refunds under Proposition 8 shall not be deducted from Taxes nor refunded to Tenant, but rather shall be the sole property of Landlord. Landlord and Tenant acknowl edge that this Section 3.01 is not intended to in any way affect (A) the inclusion in Taxes of the statutory 2.0% annual increase in Taxes (as such statutory increase may be modified by subsequent legislation), or (B) the inclusion or exclusion of Taxes pursuant to the terms of Proposition 13, which shall be governed pursuant to the terms of this Section 3. above.

4. Audit Rights. Within two (2) years after receipt of a Statement (including a Statement relating to the Base Year) by Tenant, if Tenant disputes the amount of Additional Rent set forth in the Statement, an employee of Tenant who is an accountant employed by Tenant on a full-time, non-contingency fee basis, or an independent certified public accountant (which accountant is a member of a nationally or regionally recognized accounting firm and is not working on a contingency fee basis), designated and paid for by Tenant, may, after reasonable notice to Landlord and at reasonable times, inspect Landlord’s pertinent accounting books a nd records with respect to the Statement and such supporting documentation that are reasonably related to Tenant’s review of the applicable Expenses and Taxes at Landlord’s offices in California, provided that Tenant is not then in Monetary Default under this Lease after the expiration of any applicable cure period and Tenant has paid all amounts required to be paid under the applicable Statement. In connection with such inspection, Tenant and Tenant’s agents must agree in advance to follow Landlord’s reasonable rules and procedures regarding inspections of Landlord’s records, which rules and procedures shall be consistent with the rules and procedures employed by institutional owners in the high rise office buildings industry, and shall execute a commercially reasonable confidentiality agreement regarding such inspection. Tenant’s failure to dispute the amount of Additional Rent set forth in any Statement within 2 years of Tenant’s receipt o f such Statement shall be deemed to be Tenant’s approval of such Statement and Tenant, thereafter, waives the right or ability to dispute the amounts set forth in such Statement, except for claims involving fraud or similar claims to the extent allowable under applicable Laws. If after such inspection, Tenant

5

still disputes such Additional Rent, Landlord and Tenant shall meet in order to resolve the dispute. If Landlord and Tenant are unable to resolve the dispute, a determination as to the proper amount shall be made, at Tenant’s expense, by an independent certified public accountant not previously engaged by either Landlord or Tenant (the “Accountant”), who shall be mutually and reasonably selected by Landlord and Tenant; provided that if such determination by the Accountant proves that Expenses and Taxes were, in the aggregate, overstated by more than 5%, then the cost of the Accountant, the cost of Tenant’s accountant, and the cost of such determination shall be paid for by Landlord. If such audit or review by the Accountant reveals that Landlord has overcharged or undercharged Tenant, then within thirty (30) days after the results of such audit, Landlord shall reimburse Ten ant the amount of the overcharge or Tenant shall pay the amount of the undercharge, as applicable. Tenant hereby acknowledges that Tenant’s sole right to inspect Landlord’s books and records and to contest the amount of Expenses and Taxes payable by Tenant shall be as set forth in this Section 4, and Tenant hereby waives any and all other rights pursuant to applicable Law to inspect such books and records and/or to contest the amount of Expenses and Taxes payable by Tenant, except for claims involving fraud or similar claims to the extent allowable under applicable Laws.

EXHIBIT C

WORK LETTER

This Exhibit is attached to and made a part of the Lease by and between CA-10960 WILSHIRE LIMITED PARTNERSHIP, a Delaware limited partnership (“Landlord”) and BOINGO WIRELESS, INC., a Delaware corporation (“Tenant”) for space in the Building located at 10960 Wilshire Boulevard, Los Angeles, California.

A. Tenant, following the delivery of the Premises by Landlord and the full and final execution and delivery of the Lease to which this Exhibit is attached and all prepaid rental, letter of credit and security deposits required under such agreement, shall have the right to perform alterations and improvements in the Premises (the “Initial Alterations”). Notwithstanding the foregoing, Tenant and its contractors shall not have the right to perform Initial Alterations in the Premises unless and until Tenant (and its contractors) has delivered to Landlord evidence of insur ance as required under the Lease and this Work Letter, and has received Landlord’s approval of the plans for the Initial Alterations, or a portion thereof, to be performed and the contractors to be retained by Tenant to perform such Initial Alterations in accordance with the terms of this Work Letter. Landlord acknowledges and agrees that, notwithstanding anything to the contrary contained in this Work Letter, Tenant shall be entitled to submit all plans for the Initial Alterations, including demolition and preliminary construction work, Final Space Plans and Final Working Drawings, in increments and the terms herein for approval of plans shall apply independently to each such increment. This Work Letter and not Article 9 of the Lease shall govern and control the initial design and construction of the Initial Alterations. Tenant shall be responsible for all elements of the design of Tenant’s plans (including, without limitation, compliance with law, functionality of design, the str uctural integrity of the design, the configuration of the Premises and the placement of Tenant’s furniture, appliances and equipment), and Landlord’s approval of Tenant’s plans shall in no event relieve Tenant of the responsibility for such design. Landlord’s review of Tenant’s plans shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same, for quality, design, compliance with law, or other like matters. Accordingly, notwithstanding that any of Tenant’s plans are reviewed by Landlord or its space planner, architect, engineers and consultants, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space planner, architect, engineers, and consultants, Landlord shall have no liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained in any of Tenant’s plans, and Tenant’s waiver and indemnity set fort h in Article 13 of the Lease shall specifically apply to the Tenant’s plans, except to the extent that, despite Tenant’s objection thereto based upon identified omissions or errors, Landlord has required a modification to the plans as a condition to Landlord’s approval thereof. Landlord’s approval of the contractors to perform, and the architect and engineers to design, the Initial Alterations shall not be unreasonably withheld and shall be granted or denied within five (5) Business Days of submission by Tenant, provided that Landlord hereby pre-approves Howard Building Corporation as Tenant’s general contractor, H.O.K. as the architect, and CRESA as Tenant’s project manager, as well as the architects, engineers and other consultants identified on Schedule 1 annexed hereto and made a part hereof. Landlord shall have the right to reasonably approve of any subcontractors used in connection with the Initial Alterations, pr ovided that Landlord shall have the right to require a particular subcontractor to perform fire life-safety work in connection with the tie-in of Tenant’s systems to the Base Building Systems at the point of connection therefor (provided that such subcontractor required by Landlord to be used shall be competitively priced taking into account the quality of work, experience, and reputation of such required subcontractor). Any subcontractors, laborers, materialmen, and suppliers retained to perform drywall and/or acoustical ceiling work shall all be union labor in compliance with the then existing master labor agreements. The parties agree that Landlord’s approval of the general contractor or any subcontractor to perform the Initial Alterations shall not be considered to be unreasonably withheld if any such general contractor or subcontractor, as the case may be, (i) does not have trade references reasonably acceptable to Landlord, (ii) does not maintain insurance (or name Landlord as an additional insured on such insurance) in amounts and with such coverage as may be reasonably required by Landlord, including, without limitation, (a) worker’s compensation insurance covering all of their respective employees, and (b) public liability insurance, including property damage, all with limits, in form and with companies as required to be carried by Tenant as set forth in Section 14 of the Lease to the extent such limits of liability and such insurance companies are generally required by landlords of Comparable Buildings and customary for such respective contractors and subcontractors employed by tenants constructing improvements in such Comparable Buildings), (iii) does not provide current financial statements reasonably acceptable to Landlord, or (iv) is not licensed as a contractor in the state/municipality in which the Premises is located. Tenant acknowledges the foregoing is not intended to be an exclusive list of the reasons why Landlord may reasonably withhold its consent to a general contractor. To the extent reasonably required by Landlord, Tenant or Tenant’s general contractor shall carry “Builder’s All Risk” insurance in an amount not to exceed the amount of the contract for the Initial Installations covering the

7

construction of the Initial Alterations, it being understood and agreed that the Initial Alterations shall be insured by Tenant pursuant to Section 14 of the Lease immediately upon completion thereof. Landlord agrees that its approval of any plans shall not be withheld unless such plans or the Initial Alterations create an “Initial Alterations Design Problem” (as that term is defined below). An “Initial Alterations Design Problem” is defined as, and will be deemed to exist if Tenant’s plans or any Initial Alterations may (a) affect the exterior appearance of the Premises or Building; (b) adversely affect the Building Structure; (c) adversely affect the Base Building Systems; (d) unreasonably interfere with any other occupant’s normal and customary office operation, (e) adversely affect the certificate of occupancy issued for the Building, or (f) fail to comply with applicable Law.

B. Landlord’s Approval. Landlord’s approval of any Tenant plans (including, without limitation, Tenant’s engineering and construction drawings relating to the Initial Alterations) and any other items submitted for Landlord approval hereunder (unless a lesser time is specified) shall be granted or denied by Landlord within five (5) Business Days following Tenant’s request therefor. Notwithstanding the foregoing, Landlord shall only disapprove Tenant’s other plans for an Initial Alterations Design Problem. Any resubmittal of any other Tenant plans to Landlord following Landlord’s disapproval thereof shall be reviewed by Landlord with approval thereof being granted or denied within three (3) Business Days following Landlord’s receipt of the revised other Tenant plans or such resubmittal shall be deemed approved. In the event that Landlord disapproves of any other Tenant plans pursuant to this Section B, then Tenant shall have such Tenant plans revised and resubmitted to Landlord.

C. Final Working Drawings. Tenant, Tenant’s architect and Tenant’s engineers shall complete the architectural and engineering drawings for the Initial Alterations, and the final architectural working drawings in a form which is complete to allow subcontractors to bid on the work and to obtain the Required Permits (collectively, the “Final Working Drawings”) and shall submit the same to Landlord for Landlord’s approval. Landlord shall, within five (5) Business Days after Landlord’ ;s receipt of the Final Working Drawings, either (i) approve the Final Working Drawings, (ii) approve the Final Working Drawings subject to specified conditions (which conditions must be stated in a reasonably clear manner) to be satisfied by Tenant prior to submitting the Final Working Drawings for the Required Permits, to the extent the Final Working Drawings contain an Initial Alterations Design Problem, or (iii) disapprove the Final Working Drawings for an Initial Alterations Design Problem and return the same to Tenant with requested revisions; provided, however, that Landlord shall only disapprove the Final Working Drawings if they contain an Initial Alterations Design Problem. If Landlord disapproves the Final Working Drawings, Tenant shall resubmit the Final Working Drawings to Landlord, and Landlord shall approve or disapprove of the resubmitted Final Working Drawings, based upon the criteria set forth in this Section C, within five (5) Business Days after Landlord rec eives such resubmitted Final Working Drawings. Such procedure shall be repeated until the Final Working Drawings are approved by Landlord. If Landlord fails to timely respond to Tenant within any applicable response period referenced herein for Landlord’s approval of the Final Working Drawings, then Tenant shall deliver a second notice requesting Landlord’s response to such Final Working Drawings and if Landlord thereafter fails to respond within three (3) Business Days, Landlord’s approval shall be deemed granted.

D. Required Permits. The Final Working Drawings shall be approved by Landlord pursuant to Section C. above, (as approved, the “Approved Working Drawings”) prior to the commencement of the construction of the Initial Alterations. Tenant shall cause Tenant’s space planner to promptly submit the Approved Working Drawings to the appropriate municipal authorities to obtain the required permits for construction of the Initial Alterations (the “Required Permits”). At the time of Landlord’s approval of the Final Working Drawings, Landlord shall advise Tenant in writing as to which portions of the Initial Alterations, if any, constitute additional Required Removables (in addition to those expressly identified in Section 8 of the Lease) which shall be removed by Tenant prior to the Termination Date pursuant to the terms of Section 8 of the Lease; provided, however, in no event shall Landlord require Tenant to remove any Initial Alterations that constitute typical general office improvements or do not cost more than general office improvements to demolish. Notwithstanding anything to the contrary set forth in this Section D, Tenant hereby agrees that neither Landlord nor Landlord’s consultants shall be responsible for obtaining any building permit or certificate of occupancy for the Premises, and that the obtaining of the same shall be Tenant’s responsibility; provided, however, that Landlord shall, in any event, cooperate wi th Tenant in executing permit applications and performing other ministerial acts reasonably necessary to enable Tenant to obtain any such permit or certificate of occupancy; provided further, however, any third party costs actually and reasonably incurred by Landlord in so cooperating shall be promptly reimbursed by Tenant; provided, further, that Landlord shall be responsible for any Property and Building violations or applicable Laws to the extent required by applicable laws governing general office use (as opposed to Tenant’s contemplated specific use of the Premises) and to the extent required by the City of Los Angeles as a condition to the issuance of the Required Permits and/or any certificate of occupancy. No material changes, modifications or alterations in the Approved Working Drawings may be made

8

without the prior written consent of Landlord in accordance with the terms of Section E below.

E. Change Orders. In the event Tenant desires to change the Approved Working Drawings, Tenant shall deliver written notice (the “Drawing Change Notice”) of the same to Landlord, setting forth in detail the changes (the “Tenant Change”) Tenant desires to make to the Approved Working Drawings. Landlord shall, no later than (A) five (5) Business Days after receipt of a Drawing Change Notice to the extent the modification would reasonably require material engineering or architectural review (e.g., any change which could reasonable cause an Initial Alteration Design Problem), or (B) five (5) Business Days after receipt of any other Drawing Change Notice, either (i) approve the Tenant Change, or (ii) disapprove the Tenant Change and deliver written notice to Tenant specifying in reasonably sufficient detail the reasons for Landlord’s disapproval; provided, however, that Landlord may only disapprove of the Tenant Change if the Tenant Change creates an Initial Alterations Design Problem. If Landlord fails to timely respond to Tenant within any applicable response period referenced herein for Landlord’s approval of the Tenant Change, then Tenant shall deliver a second notice requesting Landlord’s response to such Tenant Change and if Landlord thereafter fails to respond within three (3) Business Days, Landlord’s approval shall be deemed granted.

If the Initial Alterations exceed the Allowance, Tenant shall be entitled to the Allowance in accordance with the terms hereof, but each individual disbursement of the Allowance shall be disbursed in the proportion that the Allowance bears to the total cost for the Initial Alterations. Notwithstanding anything herein to the contrary, Landlord shall not be obligated to disburse any portion of the Allowance during the continuance of an uncured Monetary Default under the Lease, and Landlord’s obligation to disburse shall only resume when and if such default is cured.

If Tenant does not submit a request for payment of the entire Allowance to Landlord in accordance with the provisions contained in this Exhibit by December 31, 2008 (subject to extension for any Commencement Date Delays in accordance with Section K below), any unused amount shall accrue to the sole benefit of Landlord, it being understood that Tenant shall not be entitled to any credit, abatement or other concession in connection therewith. Notwithstanding anything to the contrary contained therein, Tenant shall be entitled to: (i) receive a credit against Base Rent coming due under the Lease, and/or (ii) purchase furniture, fixtures and equipment for use within the Premises in an amount, at Tenant’s election, of up to $251,030.00 (i.e., $10.00 per rentable square foot of the Premises). In the event Tenant elects to apply all or a portion of the Allowance as a credit against Base Rent such credit may be applied against Base Rent for the 8th full calendar month of the Term and thereafter but for periods prior to December 31, 2008. In the event Tenant elects to use any portion of the Allowance for the purchase of furniture, fixtures and equipment for use within the Premises, subject to the maximum set forth above, Landlord shall disburse the Allowance, or applicable portion thereof, to Tenant within 30 days after the later to occur of: (x) receipt of invoices from Tenant with respect to Tenant’s actual costs of the furniture, fixtures and equipment as described above, and (y) the date Landlord delivers the Premises to Tenant.

I. AS-IS CONDITION. Tenant agrees to accept the Premises in its “as-is” condition and configuration, it being agreed that Landlord shall not be required to perform any work or, except as provided above with respect to the Allowance, incur any costs in connection with the construction or demolition of any improvements in the Premises; provided, however, that the foregoing shall in no way limit or alter Landlord’s ongoing obligations under Sections 5 and/or 9.02 of this Lease . In connection with Tenant’s construction of the Initial Alterations, Landlord shall comply with all Laws relating to Base Building, provided that compliance with such Laws is not the responsibility of Tenant under this Lease, and provided further that Landlord’s failure to comply therewith would prohibit Tenant from obtaining or maintaining a certificate of occupancy (or its legal equivalent) for the Premises. Landlord shall be permitted to include in Expenses any costs or expenses incurred by Landlord under Paragraph I to the extent consistent with the terms of Exhibit B, attached hereto. Further, Landlord agrees that the Base Building electrical, HVAC (i.e., heating, ventilation and air conditioning) and plumbing systems shall be, on the date the Premises are delivered to Tenant, in good working order.

J. Inapplicability to Other Premises. This Exhibit C shall not be deemed applicable to any additional space added to the Premises at any time or from time to time, whether by any options under the Lease or otherwise, or to any portion of the original Premises or any additions to the Premises in the event of a renewal or extension of the original Term of the Lease, whether by any options under the Lease or otherwise, unless expressly so provided in the Lease or any amendm ent or supplement to the Lease.

K. Commencement Date Delays. The Commencement Date shall occur as provided in Section 1.06 of this Lease; provided that the “Build-Out Period” shall be extended on a day-for-day basis by the number of actual days of delay of the “Substantial Completion of the Initial Alterations,” as that term is defined in Section K.2 below beyond November 1, 2007, to the extent actually and directly caused by a “Commencement Date Delay,” as that term is defined below. A s used herein, the term “Commencement Date Delay” shall mean only a “Force Majeure Delay” or a “Landlord Caused Delay,” as those terms are defined below in this Section K.

A “Landlord Caused Delay” shall mean actual delays to the extent resulting from the acts or omissions of Landlord or the Landlord Related Parties, including, without limitation, (i) except to

10

the extent Landlord’s approval under this Work Letter is deemed granted pursuant to the terms of this Work Letter, failure of Landlord to timely approve or disapprove the Final Space Plan, Final Working Drawings, any Tenant Change, or any other plans or specifications for the Initial Alterations within the time periods set forth in this Work Letter or the Lease, as applicable, or otherwise within a reasonable period of time; (ii) material and unreasonable interference by Landlord, its agents, or the Landlord Related Parties (except as otherwise allowed under this Work Letter) with the Substantial Completion of the Initial Alterations and which objectively preclude or delay the construction of tenant improvements in the Building or any portion thereof, which interference relates to access by Tenant, or Tenant’s agents to the Building or any reasonably necessary Building facilities (including loading docks and freight elevators) or service and utilities (including temporary power and parking areas as provided herein) on a twenty-four (24) hour per day, seven (7) days per week, basis; (iii) a material breach by Landlord of a provision of this Work Letter or as specifically provided in this Work Letter; (iv) Landlord’s failure to maintain a temporary or permanent certificate of occupancy or its alternative for the Building by the date of execution of this Lease; (v) Landlord’s failure to deliver possession of the Premises to Tenant in accordance with Section 3.02 of the Lease; and (vi) delays due to the acts or failures to act of Landlord, its agents, employees or contractors.

1. Determination of a Commencement Date Delay. If Tenant contends that a Landlord Caused Delay has occurred, Tenant shall notify Landlord in writing of the event that constitutes such Landlord Caused Delay (the “Delay Notice”). If such actions, inaction or circumstance described in the Delay Notice are not cured by Landlord within one (1) Business Day of Landlord’s receipt of the Delay Notice and if such action, inaction or circumstance otherwise qualify as a L andlord Caused Delay, then a Landlord Caused Delay shall be deemed to have occurred commencing as of the date of Landlord’s receipt of the Delay Notice and ending as of the date such delay ends. If Tenant contends that a Force Majeure Delay has occurred, Tenant shall immediately notify Landlord in writing of the event that constitutes such Force Majeure Delay (also a “Delay Notice”).

2. Definition of Substantial Completion of the Initial Alterations. For purposes of this Section K, “Substantial Completion of the Initial Alterations” shall mean the issuance of a temporary certificate of occupancy for the subject space (or its legal equivalent allowing occupancy of such space) (the “C of O”) and completion of construction of the Initial Alterations in the Premises pursuant to the Approved Working Drawings, including any furniture, fixtu res, work stations, built-in furniture or equipment necessary to obtain the C of O, with the exception of (i) any punch list items, (ii) any furniture, fixtures, work stations, built-in furniture or equipment not required to obtain the C of O (even if the same requires installation or electrification by Tenant’s agents) and (iii) any tenant improvement finish items and materials which are selected by Tenant but which are not available within a reasonable time (given the Commencement Date).

L. Parking and Other Services. During the period of design and construction of the Initial Alterations, installlation of Tenant’s furniture, fixtures and equipment, and move into the Premises, Tenant shall not be required to pay for, and Landlord shall not deduct from the Allowance, any charges for (1) contractor, subcontractor, consultants, and architect parking (subject, however, to commercially reasonable availability), or (2) the use of freight elevator (subje ct to scheduling with Landlord), restrooms, loading docks, security (except to the extent additional security personnel are required in connection therewith, in which event Tenant shall be responsible for the actual cost of such additional security personnel), or utilities (except to the extent Tenant requires HVAC outside of Normal Construction Hours [which are from 7:00 a.m. to 6:00 p.m., Mondays through Fridays, and from 8:00 a.m. to 1:00 p.m., Saturdays] and on Holidays, in which event Tenant shall reimburse Landlord at the prevailing hourly rate for such after hours HVAC service).

M. Common Areas. Notwithstanding any contrary provision of this Work Letter, Tenant shall not be required to pay (and there shall be no deduction from the Allowance) for any costs incurred by Landlord in connection with any construction in the Common Areas of the Building which is required for such Common Areas to comply with the building code of the City of Los Angeles, unless such work is required as a result of any non-general office improvements which are being installed or constructed in the Premi ses as a part of the Initial Alterations.

If Landlord draws upon the Letter of Credit for a non-monetary default under the Lease, Tenant shall have the right to replace any proceeds of the Letter of Credit so drawn upon by Landlord and not yet applied by Landlord to cure such default and/or to compensate Landlord for the damages suffered by Landlord as a result thereof with an additional Letter of Credit up to the then required Letter of Credit Amount which complies with all of the provisions of this Section II, and Landlord shall return such unapplied proceeds to Tenant within five (5) Business Days after the later of the date Landlord receives such additional Letter of Credit and Tenant has cured s uch default. Tenant further covenants and warrants that it will neither assign nor encumber the Letter of Credit or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance.

E. Nature of Letter of Credit. Landlord and Tenant (1) acknowledge and agree that in no event or circumstance shall the Letter of Credit or any renewal thereof or substitute therefor or any proceeds thereof (including the LC Proceeds Account) be deemed to be or treated as a “security deposit” under any Law applicable to security deposits in the commercial context including Section 1950.7 of the California Civil Code, as such sectio n

2

now exist or as may be hereafter amended or succeeded (“Security Deposit Laws”), (2) acknowledge and agree that the Letter of Credit (including any renewal thereof or substitute therefor or any proceeds thereof) is not intended to serve as a security deposit, and the Security Deposit Laws shall have no applicability or relevancy thereto, and (3) waive any and all rights, duties and obligations either party may now or, in the future, will have relating to or arising from the Security Deposit Laws. Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code and all other provisions of Law, now or hereafter in effect, which (i) establish the time frame by which Landlord must refund a security deposit under a lease, and/or (ii) provide that Landlord may claim from the Security Deposit only those sums reasonably necessary to remedy defaults in the pay ment of rent, to repair damage caused by Tenant or to clean the Premises, it being agreed that Landlord may, in addition, claim those sums specified in this Section II above and/or those sums reasonably necessary to compensate Landlord for any loss or damage caused by Tenant’s breach of this Lease or the acts or omission of Tenant or any other Tenant Related Parties, including any damages Landlord suffers following termination of the Lease.

F. Reduction in Letter of Credit Amount.

1. Provided that Tenant has met Landlord’s “LC Reduction Conditions” as defined in Section II.F.2 below, Tenant shall be entitled to reduce the Letter of Credit Amount to the amounts set forth below on the dates set forth below (“Target Reduction Date”) so that the reduced Letter of Credit Amounts will be as follows: (a) $480,000.00 on the first day of the 24 th full calendar month of the Term; (b) $360,000.00 on the first day of the 36 th full calendar month of the Term; and (c) $240,000.00 on the first day of the 48 th full calendar month of the Term. If Tenant is not entitled to reduce the Letter of Credit Amount as of a particular Target Reduction Date due to Tenant’s failure to satisfy the LC Reduction Conditions described below, then upon satisfying the LC Reduction Conditions, the Letter of Credit Amount s hall be reduced by the amount of the reduction Tenant would have been entitled to had Tenant satisfied the LC Reduction Conditions necessary for such reduction. Any reduction in the Letter of Credit Amount shall be accomplished by Tenant providing Landlord with a substitute letter of credit in the reduced amount or an amendment to the existing Letter of Credit reflecting the reduced amount. If Tenant is entitled to reduce the Letter of Credit, Landlord agrees to provide any authorizations required by the Bank to accomplish such reduction upon the Bank’s written request to Landlord. In the event Landlord fails to take the required action to provide any such authorizations required by the Bank within ten (10) Business Days from receipt of Tenant’s written notice requesting Landlord’s required action, Tenant shall deliver a second written notice to Landlord requesting Landlord’s required action which notice shall conspicuously state that Landlord’s failure to act will result in a furthe r reduction of the Letter of Credit.

2. Definitions.

(i) For purposes hereof, the “LC Reduction Conditions” shall be deemed to have been satisfied as of any Target Reduction Date if and only if no Monetary Default exists under the Lease as of such Target Reduction Date.

III. TELECOMMUNICATIONS PROVIDERS. Tenant shall be permitted, at its sole cost and expense, to contract with any telecommunications provider of its choice; provided, however, such telecommunications provider shall be subject to Landlord’s approval, which approval shall not be unreasonably withheld, conditioned or delayed; provided, further, subject to the terms of this Lease, including Article 5 and subject to the reasonable, non-discriminatory rules and regulations of Landlord, Landlord shall provide Tenant’s telecommunications provider(s) access to the Building’s risers and rooftop, when accompanied and supervised by an authorized representative of Landlord (unless such representative is not reasonably available), for the purpose of installing any necessary cabling, wiring and conduit (but not any other equipment, such as equipment racks, or telephone switches) in accordance with plans and specifications approved in writing, in advance, by Landlord, which approval shall not be unreasonably withheld or conditioned and shall be granted or denied within ten (10) Business Days. Notwithstanding the foregoing, Tenant shall remove any such cabling or wiring installed by Tenant within any conduit installed by Tenant upon the expiration or earlier termination of the Term and repair any damage caused by such removal at its sole cost and expense, provided that Tenant shall not be obligated to remove such conduit.

IV. SECURED AREAS. Notwithstanding anything to the contrary set forth in the Lease, Tenant may

3

designate certain areas of the Premises as “Secured Areas” should Tenant require such areas for the purpose of securing certain valuable property or confidential information. In connection with the foregoing, Landlord shall not enter such Secured Areas except in the event of an emergency. Landlord need not clean any area designated by Tenant as a Secured Area and shall only maintain or repair such secured areas to the extent (i) such repair or maintenance is required in order to maintain and repair the Building Structure and/or the Building Systems, or (ii) is required by Law.

V. PROPERTY MANAGER ACCESS. Landlord shall provide a commercially reasonable system pursuant to which Tenant, in the event of an emergency, may promptly contact the Property manager and Property engineer or their equivalent twenty-four (24) hours a day seven (7) days a week (whether or not within normal business hours).

VI. TENANT’S SPECIAL OFFSET RIGHT. In the event Tenant obtains a final non-appealable monetary judgment from a court of competent jurisdiction against Landlord resulting from Landlord’s default under this Lease, and Landlord fails to pay the amount of such monetary judgment to Tenant within thirty (30) days after such judgment is entered against Landlord, and such failure continues for an additional thirty (30) days after notice from Tenant that Tenant intends to exercise its rights under this Section VI, then Ten ant may offset against the Rent next due and payable under this Lease, the amount of such monetary judgment so entered against Landlord.

VII. ENVIRONMENTAL REPRESENTATION.

A. Landlord represents, to its knowledge based solely upon (i) that certain Phase I Environmental Site Assessment by Earth Tech, Inc. dated September 4, 1996, (ii) that certain Asbestos Survey Report by RGA Environmental, Inc., dated May 27, 2004 and (iii) the current actual knowledge of Mr. David Hitzel, Building Leasing Representative, and Ms. Katrina Jones, Building General Manager, that the Premises are free of Hazardous Materials (as defined below) in amounts and conditions which are in violation of applicable environmental laws.

B. Tenant shall not use, generate, manufacture, store or dispose of, on or about the Premises or Property, or transport to or from the Premises, Building or Property, any Hazardous Materials. Notwithstanding the provisions of this Section VII, Tenant and Landlord shall have the right to use, generate and store on the Premises and the Building, and transport to and from the Premises and the Building, those Hazardous Materials which are generally used in the ordinary course in first class office buildings; provided, however, that Tenant’s and Landlord’s use, gener ation, storage and transport thereof is in compliance with all applicable federal, state and local laws, regulations and ordinances.

C. As used in this Lease, “Hazardous Materials” shall mean any material or substance that is now or hereafter defined or regulated by any statute, regulation, ordinance, or governmental authority thereunder, as radioactive, toxic, hazardous, or waste, or a chemical known to the state of California to cause cancer or reproductive toxicity, including but not limited to (i) petroleum and any of its constituents or byproducts, (ii) radioactive materials, (iii) asbestos in any form or condition, and (iv) substances or materials regulated by any of the following, as amend ed from time to time, and any rules promulgated thereunder: the Comprehensive Environmental Response Compensation and Liability Act of 1980, 42 U.S.C. §§9601 et seq.; the Resource Conservation and Recovery Act, 42 U.S.C. §§6901, et seq.; the Toxic Substances Control Act, 15 U.S.C. §§2601, et seq.; the Clean Water Act, 33 U.S.C. §§1251 et seq; the Clean Air Act, 42 U.S.C. §§7401 et seq.; The California Health and Safety Code; The California Water Code; The California Labor Code; The California Public Resources Code; The California Fish and Game Code.

VIII. ADDITIONAL PROVISIONS. Notwithstanding anything to the contrary contained in the Lease:

A. Permitted Use. No portion of the Premises shall be used for any of the following uses: any pornographic or obscene purposes, any commercial sex establishment, any pornographic, obscene, nude or semi-nude performances, modeling, materials, activities, or sexual conduct or any other use that, as of the time of the execution hereof, has or could reasonably be expected to have a material adverse effect on the Property or its use, operation or value.

B. Attornment. In the event of the enforcement by any Mortgagee of any remedy under any Mortgage or Mortgage loan document, Tenant shall, at the option of the Mortgagee or of any other person or entity succeeding to the interest of the Mortgagee as a result of such enforcement, attorn to the Mortgagee or to such person or entity and shall recognize the

4

Mortgagee or such successor in the interest as lessor under the Lease without change in the provisions thereof; provided, however, the Mortgagee or such successor in interest shall not be liable for or bound by (i) any payment of an installment of Rent or Additional Rent which may have been made more than 30 days before the due date of such installment, (ii) any act or omission of or default by Landlord under the Lease (but the Mortgagee, or such successor, shall be subject to the continuing obligations of Landlord to the extent arising from and after such succession to the extent of the Mortgagee’s, or such successor’s, interest in the Property), (iii) any credits, claims, setoffs or defenses which any Tenant may have against Landlord, or (iv) any obligation under the Lease to maintain a fitness facility at the Property. Tenant, upon the reasonable request by the Mortg agee or such successor in interest, shall execute and deliver a commercially reasonable instrument or instruments confirming such attornment. Notwithstanding the foregoing, in the event the Mortgagee shall have entered into a separate subordination, attornment and non-disturbance agreement directly with Tenant governing Tenant’s obligation to attorn to the Mortgagee or such successor in interest as lessor, the terms and provisions of such agreement shall supersede the provisions of this Subsection.

C. Proceeds.

1. Nothing in the Lease shall be deemed to prevent Proceeds (defined below) from being held and disbursed by any Mortgagee in accordance with the terms of the applicable Mortgage loan documents. However, if, in the event of any Casualty or partial Taking, any obligation of Landlord under the Lease to restore the Premises or the Building is materially diminished by the operation of the preceding sentence, then Landlord, as soon as reasonably practicable after the occurrence of such Casualty or partial Taking, shall provide written notice to Tenant describing such diminuti on with reasonably specificity, whereupon Tenant, by written notice to Landlord delivered within 10 days after receipt of Landlord’s notice, shall have the right to terminate the Lease effective 10 days after the date of such termination notice.

2. Nothing in the Lease shall be deemed to entitle Tenant to receive and retain Proceeds except those that may be specifically awarded to it in condemnation proceedings because of the Taking of its trade fixtures and its leasehold improvements which have not become part of the Property and such business loss as Tenant may specifically and separately establish. Nothing in the preceding sentence shall be deemed to expand any right Tenant may have under the Lease to receive or retain any Proceeds.

3. As used herein, “Proceeds” means any compensation, awards, proceeds, damages, claims, insurance recoveries, causes or rights of action (whenever accrued) or payments which Landlord may receive or to which Landlord may become entitled with respect to the Property or any part thereof (other than payments received in connection with any liability or loss of rental value or business interruption insurance) in connection with any Taking of or any Casualty or other damage or injury to the Property or any part thereof.

IX. PREMISES FURNITURE. Landlord and Tenant acknowledge and agree that the prior tenant in the Premises surrendered or will surrender the Premises with certain items of furniture remaining in the Premises, which furniture is listed on Exhibit F-1 hereto, (the “Premises Furniture”). Landlord consents to Tenant’s use of the Premises Furniture free of charge during the Term, as extended. Tenant accepts such Premises Furniture for use during the Term in as-is, where-is condition with no representations or warranties from Landlord as to title, quality, condition, merchantability or fitness for use; any such warranties being specifically excluded. Tenant shall maintain the Premises Furniture in good condition and repair during the Term, at Tenant’s sole cost and expense, and upon expiration of the Term shall surrender the Premises Furniture to Landlord in as good a condition as at the Commencement Date, ordinary wear and tear excepted. Notwithstanding anything to the contrary contained herein, Tenant shall be entitled to modify, reconfigure, and/or replace the Premises Furniture during the Term and if Tenant does not desire to continue to use any of the Premises Furniture during the Term, Tenant shall give written notice thereof to Landlord and Landlord may either promptly take possession of such Premises Furniture or instruct Tenant to dispose of or store the same at Tenant’s sole cost and expense (including, but not limited to, shipping, storage or disposal fees).

X. RENEWAL OPTION.

A. Subject to the terms herein, Tenant shall have the right to extend the Term (the “Renewal Option”) for one additional period of 5 years commencing on the day following the

5

Termination Date of the initial Term and ending on the 5 th anniversary of the Termination Date (the “Renewal Term”).

It is agreed that Tenant may exercise a Renewal Option only if:

1. Landlord receives notice of exercise (“Renewal Notice”) not less than 9 full calendar months prior to the expiration of the initial Term and not more than 12 full calendar months prior to the expiration of the initial Term; and

2. Tenant is not in Monetary Default under the Lease beyond any applicable notice and cure periods at the time that Tenant delivers its Renewal Notice or at the time Tenant delivers its Binding Notice (hereinafter defined); and

3. more than 30% of the Rentable Square Footage of the Premises is sublet at the time that Tenant delivers its Renewal Notice or at the time Tenant delivers its Binding Notice, other than to an Affiliate of Tenant under Section 11 of the Lease; and

4. The Lease has not been assigned (other than to its Affiliate) prior to the date that Tenant delivers its Renewal Notice or prior to the date Tenant delivers its Binding Notice.

B. The Rent rate per rentable square foot for the Premises during the Renewal Term (the “Renewal Rent”) shall equal the “Prevailing Market” (hereinafter defined) rate per rentable square foot for the Premises.

C. Subject to the Prevailing Market determination (which shall include a determination of any new “base year” or “expense stop”), Tenant shall pay Additional Rent (i.e. Expenses and Taxes) for the Premises during the Renewal Term in accordance with Section 4 and Exhibit B of the Lease, and the manner and method in which Tenant reimburses Landlord for Tenant’s share of Taxes and Expenses and the Base Year, if any, applicable during the Renewal Term, shall be some of the factors considered in determining the Prevailing Mar ket rate for the Renewal Term.

D. Initial Procedure for Determining Prevailing Market. Within 30 days after receipt of Tenant’s Renewal Notice, Landlord shall advise Tenant in writing (the “Rent Notice”) of Landlord’s determination of the Renewal Rent for the Premises for the Renewal Term. Tenant, within 30 days after the date on which Landlord advises Tenant of Landlord’s determination of the Renewal Rent for the Renewal Term, shall either (i) give Landlord final binding written notice (the “Binding Notice 8;) of Tenant’s exercise of its Renewal Option, or (ii) give Landlord notice that Tenant is not exercising the Renewal Option (the “Rejection Notice”). If Tenant fails to provide Landlord with either a Binding Notice or Rejection Notice within such 30 day period, Tenant’s Renewal Option shall be null and void and of no further force and effect. If Tenant provides Landlord with a Binding Notice, Landlord’s determination of the Renewal Rent as set forth in the Rent Notice shall be conclusive and binding, and Landlord and Tenant shall enter into the Renewal Amendment (as defined below) upon the terms and conditions set forth herein, unless upon and concurrent with such exercise, Tenant objects to the Renewal Rent contained in Landlord’s Rent Notice, in which case the parties shall follow the procedure, and the Renewal Rent shall be determined, as set forth below. If Tenant provides Landlord with a Binding Notice, but Tenant objects to Landlord’s determi nation of the Renewal Rent, Landlord and Tenant shall work together in good faith to agree upon the Prevailing Market rate for the Premises during the Renewal Term. Upon agreement (or, if applicable, following the determination of the Renewal Rent in accordance with Section X.E of this Exhibit F), Landlord and Tenant shall enter into the Renewal Amendment in accordance with the terms and conditions hereof. Notwithstanding the foregoing, if Landlord and Tenant fail to agree upon the Prevailing Market rate within 30 days after the date Tenant provides Landlord with the Binding Notice (the “Outside Agreement Date”), then the parties shall each make a separate determination of the Prevailing Market rate and shall submit the same to the arbitrators pursuant to the terms of Section X.E of this Exhibit F. The submittals shall be made concurrently with the selection of the arbitrators pursuant to Section X.E of this Exhibit F and shall b e submitted to arbitration in accordance with Sections X.E.1 through X.E.7 of this Exhibit F, but subject to the terms, when appropriate, of Section X.G of this Exhibit F.

E. Arbitration Procedure.

1. Landlord and Tenant shall each appoint one arbitrator who shall by profession be a real estate broker or lawyer who shall have been active over the 5 year period

6

ending on the date of such appointment in the leasing of first class office properties in the area commonly known as “Westwood”. The determination of the arbitrators shall be limited solely to the issue of whether Landlord’s or Tenant’s submitted Prevailing Market rate is the closest to the actual Prevailing Market rate as determined by the arbitrators, taking into account the requirements of Section X.G of this Exhibit F. Each such arbitrator shall be appointed within 15 days after the Outside Agreement Date. Landlord and Tenant may consult with their selected arbitrators prior to appointment and may select an arbitrator who is favorable to their respective positions (including an arbitrator who has previously represented Landlord and/or Tenant, as applicable). The arbitrators so selected by Landlord and Tenant shall be deemed “Advocate Arbit rators.”

2. The two Advocate Arbitrators so appointed shall be specifically required pursuant to an engagement letter within 10 days of the date of the appointment of the last appointed Advocate Arbitrator to agree upon and appoint a third arbitrator (“Neutral Arbitrator”) who shall be qualified under the same criteria set forth hereinabove for qualification of the two Advocate Arbitrators except that (i) neither the Landlord or Tenant or either parties’ Advocate Arbitrator may, directly or indirectly, consult with the Neutral Arbitrator prior or subseq uent to his or her appearance, and (ii) the Neutral Arbitrator cannot be someone who has represented Landlord and/or Tenant during the 5 year period prior to such appointment. The Neutral Arbitrator shall be retained via an engagement letter jointly prepared by Landlord’s counsel and Tenant’s counsel.

3. The three arbitrators shall within 30 days of the appointment of the Neutral Arbitrator reach a decision as to Prevailing Market rate and determine whether the Landlord’s or Tenant’s determination of Prevailing Market rate as submitted pursuant to this Section X.E of this Exhibit F is closest to Prevailing Market rate as determined by the arbitrators and simultaneously publish a ruling (“Award”) indicating whether Landlord’s or Tenant’s submitted Prevailing Market rate is closest to the Prevailing Market rate as de termined by the arbitrators. Following notification of the Award, the Landlord’s or Tenant’s submitted Prevailing Market rate determination, whichever is selected by the arbitrators as being closest to Prevailing Market rate, shall become the then applicable Prevailing Market rate.

4. The Award issued by the majority of the three arbitrators shall be binding upon Landlord and Tenant.

5. If either Landlord or Tenant fail to appoint an Advocate Arbitrator within 15 days after the applicable Outside Agreement Date, either party may petition the presiding judge of the Superior Court of Los Angeles County to appoint such Advocate Arbitrator subject to the criteria in this Section X.E of this Exhibit F, or if he or she refuses to act, either party may petition any judge having jurisdiction over the parties to appoint such Advocate Arbitrator.

6. If the two Advocate Arbitrators fail to agree upon and appoint the Neutral Arbitrator, then either party may petition the presiding judge of the Superior Court of Los Angeles County to appoint the Neutral Arbitrator, subject to criteria in this Section X.E of this Exhibit F, or if he or she refuses to act, either party may petition any judge having jurisdiction over the parties to appoint such arbitrator.

7. The cost of arbitration shall be paid by Landlord and Tenant equally.

F. Renewal Amendment. If Tenant is entitled to and properly exercises its Renewal Option, Landlord shall prepare an amendment (the “Renewal Amendment”) to reflect changes in the Base Rent, Term, Termination Date and other appropriate terms. The Renewal Amendment shall be sent to Tenant within a reasonable time after receipt of the Binding Notice (or, if the Binding Notice is timely delivered to Landlord and Tenant concurrently objects to Landlord’s determination of the Renewal Rent, following mutual agreement of the Renewal Rent or following the determination of the Renewal Rent in accordance with Section X.E of this Exh ibit F, as the case may be) and Tenant shall execute and return an accurate Renewal Amendment to Landlord within 15 Business Days after Tenant’s receipt of same; provided, however, an otherwise valid exercise of the Renewal Option shall be fully effective whether or not the Renewal Amendment is executed.

G. Prevailing Market. For purposes hereof, “Prevailing Market” shall mean the rent (including additional rent and considering any “base year’ or “expense stop” applicable thereto), including all escalations, at which tenants, as of the commencement of the applicable Renewal Term, are leasing “Comparable Space” (defined below) for a term of 5 years in an arm’s-length

7

transaction, which Comparable Space is located in the Building and “Comparable Buildings” (as defined in Section 1.17 of the Lease), and which comparable transactions (collectively, the “Comparable Transactions”) are entered into within the 6 month period immediately preceding Landlord’s delivery of the Rent Notice, taking into consideration the following concessions (the “Concessions”): (a) rental abatement concessions, if any, being granted such tenants in connection with such Comparable Space; (b) tenant improvements or allowances provided or to be provided for such Comparable Space; and (c) other reasonable monetary concessions being granted such tenants in connection with such Comparable Space; provided, however, that in calculating the Prevailing Market rate, no consideration shall be given to (i) the fact that Landlord is or is not required to pay a real estate brokerage commission in connection with Tenant’s exercise of its right to lease the Premises during the Renewal Term or in connection with the Comparable Transactions or the fact that landlords are or are not paying real estate brokerage commissions in connection with such Comparable Space, and (ii) any period of rental abatement, if any, granted to tenants in Comparable Transactions in connection with the design, permitting and construction of tenant improvements in such Comparable Space. “Comparable Space” shall mean non-sublease, non-encumbered, non-equity, non-renewal (unless the tenant was represented by a broker), non-expansion space comparable in size, location and quality to the Premises space comparable to the Premises.

XI. ROOF SPACE FOR DISH/ANTENNA.

A. During the Term of this Lease, as may be extended, Tenant shall have the right subject to availability as determined by Landlord, in consideration for payments (the “Dish/Antenna Payments”) of the prevailing monthly charges established from time to time for space on the roof of the Building for the purpose of installing (in accordance with Section 9.03 of the Lease), operating up to 2 dish/antennas with 1 dish/antenna being no more 24 inches and 1 dish/antenna being no more than 36 inches (the “Dish/Antenna”) together with all reasonably necessary condu its and riser space to connect the Dish/Antenna with the Premises. The exact location of the space on the roof to be leased by Tenant shall be reasonably designated by Landlord and shall not exceed 25 square feet (the “Roof Space”). Landlord reserves the right to reasonably relocate the Roof Space, at Landlord sole cost and expense, as reasonably necessary during the Term so long as Tenant’s use of the Dish/Antenna, including reception and/or transmission therefrom is not adversely affected. Landlord’s designation shall take into account Tenant’s use of the Dish/Antenna. Notwithstanding the foregoing, Tenant’s right to install the Dish/Antenna shall be subject to the reasonable approval rights (which shall not be unreasonably conditioned or delayed) of Landlord and Landlord’s architect and/or engineer with respect to the plans and specifications of the Dish/Antenna, the manner in which the Dish/Antenna is attached to the roof of the Building and the manner in w hich any cables are run to and from the Dish/Antenna to the Premises. The Dish/Antenna must be tagged with weatherproof labels showing manufacturer, model, frequency range, and name of Tenant. In addition, the cable between the Dish/Antenna and Tenant’s suite must be tagged in the telecom closet on each floor with a label showing Tenant’s name, phone number and suite number. The precise specifications and a general description of the Dish/Antenna along with all documents Landlord reasonably requires to review the installation of the Dish/Antenna (the “Plans and Specifications”) shall be submitted to Landlord for Landlord’s written approval no later than 20 days before Tenant commences to install the Dish/Antenna. Tenant shall be solely responsible for obtaining all necessary governmental and regulatory approvals and for the cost of installing, operating, maintaining and removing the Dish/Antenna. Tenant shall notify Landlord upon completion of the installation of t he Dish/Antenna. If Landlord determines that the Dish/Antenna equipment does not comply with the approved Plans and Specifications, that the Building has been damaged during installation of the Dish/Antenna or that the installation was defective, Landlord shall notify Tenant of any noncompliance or detected problems and Tenant immediately shall cure the defects. If the Tenant fails to immediately cure the defects, Tenant shall pay to Landlord upon demand the actual out-of-pocket cost, as reasonably determined by Landlord, of correcting any defects and repairing any damage to the Building caused by such installation. If at any time Landlord, in its sole discretion, deems it necessary, Tenant shall provide and install, at Tenant’s sole cost and expense, appropriate aesthetic screening, reasonably satisfactory to Landlord, for the Dish/Antenna (the “Aesthetic Screening”).

B. Landlord agrees that Tenant, upon reasonable prior written notice to Landlord, shall have access to the roof of the Building and the Roof Space for the purpose of installing, maintaining, repairing and removing the Dish/Antenna, the appurtenances and the Aesthetic Screening, if any, all of which shall be performed by Tenant or Tenant’s authorized representative or contractors, which shall be reasonably approved by Landlord, at Tenant’s sole cost and risk. It is agreed, however, that only authorized

8

engineers, employees or properly authorized contractors of Tenant, FCC (defined below) inspectors, or persons under their direct supervision will be permitted to have access to the roof of the Building and the Roof Space. Tenant further agrees to exercise firm control over the people requiring access to the roof of the Building and the Roof Space in order to keep to a minimum the number of people having access to the roof of the Building and the Roof Space and the frequency of their visits.

C. It is further understood and agreed that the installation, maintenance, operation and removal of the Dish/Antenna, the appurtenances and the Aesthetic Screening, if any, is not permitted to damage the Building or the roof thereof, or interfere with the use of the Building and roof by Landlord. Tenant agrees to be responsible for any damage caused to the roof or any other part of the Building, to the extent caused by Tenant or any of its agents or representatives.

D. Tenant agrees to install only equipment of types and frequencies which will not cause unreasonable interference to Landlord or existing tenants of the Building. In the event Tenant’s equipment causes such unreasonable interference, Tenant will change the frequency on which it transmits and/or receives and take any other steps necessary to eliminate the interference. If said interference cannot be eliminated within a reasonable period of time, in the judgment of Landlord, then Tenant agrees to remove the Dish/Antenna from the Roof Space. Landlord agrees to use com mercially reasonable efforts to cause other users of the roof to likewise eliminate any unreasonable interference to Tenant’s Dish/Antenna.

E. Tenant shall, at its sole cost and expense, and at its sole risk, install, operate and maintain the Dish/Antenna in a good and workmanlike manner, and in compliance with all Building, electric, communication, and safety codes, ordinances, standards, regulations and requirements, now in effect or hereafter promulgated, of the Federal Government, including, without limitation, the Federal Communications Commission (the “FCC”), the Federal Aviation Administration (“FAA”) or any successor agency of either the FCC or FAA having jurisdiction over radio or telecommunications, and of the state, city and county in which the Building is located. Under this Lease, the Landlord and its agents assume no responsibility for the licensing, operation and/or maintenance of Tenant’s equipment. Tenant has the responsibility of carrying out the terms of its FCC license in all respects. The Dish/Antenna shall be connected to Landlord’s power supply in strict compliance with all applicable Building, electrical, fire and safety codes. Neither Landlord nor its agents shall be liable to Tenant for any stoppages or shortages of electrical power furnished to the Dish/Antenna or the Roof Space because of any act, omission or requirement of the public utility serving the Building, or the act or omission of any other tenant, invitee or licensee or their respective agents, employees or contractors, or for any other cause beyond the reasonable control of Landlord, and Tenant shall not be entitled to any rental abatement for any such stoppage&n bsp;or shortage of electrical power. Except as provided in the Lease, neither Landlord nor its agents shall have any responsibility or liability for the conduct or safety of any of Tenant’s representatives, repair, maintenance and engineering personnel while in or on any part of the Building or the Roof Space.

F. The Dish/Antenna, the appurtenances and the Aesthetic Screening, if any, shall remain the personal property of Tenant, and shall be removed by Tenant at its own expense at the expiration or earlier termination of this Lease or Tenant’s right to possession hereunder. Tenant shall repair any damage caused by such removal, including the patching of any holes to match, as closely as possible, the color surrounding the area where the equipment and appurtenances were attached. Tenant agrees to maintain all of the Tenant’s equipment placed on or about the roof or i n any other part of the Building in proper operating condition and maintain same in satisfactory condition as to appearance and safety in Landlord’s reasonable discretion. Such maintenance and operation shall be performed in a manner to avoid any interference with any other tenants or Landlord. Tenant agrees that at all times during the Term, it will keep the roof of the Building and the Roof Space free of all trash or waste materials produced by Tenant or Tenant’s agents, employees or contractors.

G. In light of the specialized nature of the Dish/Antenna, Tenant shall be permitted to utilize the services of its choice for installation, operation, removal and repair of the Dish/Antenna, the appurtenances and the Aesthetic Screening, if any, subject to the reasonable approval of Landlord. Notwithstanding the foregoing, Tenant must provide Landlord with prior written notice of any such installation, removal or repair and coordinate such work with Landlord in order to avoid voiding or otherwise adversely affecting any warranties granted to Landlord with respect to the roof. If necessary, Tenant, at its sole cost and expense, shall retain any contractor (who shall be competitively priced) having a then existing warranty in effect on the roof to perform such work (to the extent that it

9

involves the roof), or, at Tenant’s option, to perform such work in conjunction with Tenant’s contractor. In the event the Landlord contemplates roof repairs that could affect Tenant’s Dish/Antenna, or which may result in an interruption of the Tenant’s telecommunication service, Landlord shall formally notify Tenant at least 30 days in advance (except in cases of an emergency) prior to the commencement of such contemplated work in order to allow Tenant to make other arrangements for such service.

H. Tenant shall not allow any provider of telecommunication, video, data or related services (“Communication Services”) to locate any equipment on the roof of the Building or in the Roof Space for any purpose whatsoever, nor may Tenant use the Roof Space and/or Dish/Antenna to provide Communication Services to an unaffiliated tenant, occupant or licensee of another building, or to facilitate the provision of Communication Services on behalf of another Communication Services provider to an unaffiliated tenant, occupant or licensee of the Building or any other building.

I. Tenant acknowledges that Landlord may at some time establish a standard license agreement (the “License Agreement”) with respect to the use of roof space by tenants of the Building. Tenant, upon request of Landlord, shall enter into a commercially reasonable version of such License Agreement with Landlord provided that such agreement is consistent with this Section VI and does not materially alter the rights of Tenant hereunder with respect to the Roof Space.

J. Landlord and Tenant specifically acknowledge and agree that the terms and conditions of Section 13 and 15 of the Lease (Indemnity and Waiver of Claims; Subrogation) shall apply with full force and effect to the Roof Space and any other portions of the roof accessed or utilized by Tenant, its representatives, agents, employees or contractors.

1. The capitalized terms used in this Parking Agreement shall have the same definitions as set forth in the Lease to the extent that such capitalized terms are defined therein and not redefined in this Parking Agreement. In the event of any conflict between the Lease and this Parking Agreement, the latter shall control. Landlord hereby represents and warrants that (i) Landlord has the power and authority to enter into, and to enforce, the provisions of this Parking Agreement, and (ii) notwithstanding any parking management agreement Landlord may have entered into (with regard to the day to day operation of the Parking Facility or otherwise), Landlord retains control over the Parking Facility and its operation.

2. During the Term, Tenant shall have the right, but not the obligation, to lease from Landlord up to 80 non-reserved parking spaces (the “Non-Reserved Parking Spaces”) located in the parking facility servicing the Building (“Parking Facility”). The Non-Reserved Parking Spaces are sometimes collectively referred to as the “parking spaces”. Prior to the Commencement Date, Tenant shall notify Landlord in writing of the number of Non-Reserved Parking Spaces which Tenant initially elects to use during the Term, but in no event in excess of the maximum number of Non-Reserved Parking Spaces set forth in this Section 2. Thereafter, Tenant may increase or decrease the number of Non-Reserved Parking Spaces to be used by Tenant pursuant to this Section 2 upon a minimum of 30 days prior written notice to Landlord, provided that in no event may Tenant elect to use in excess of the maximum number of Non-Reserved Parking Spaces set forth in this Section 2. During the initial Term, Tenant shall pay in advance, concurrent with Tenant’s payment of monthly Base Rent, the prevailing monthly charges established from time to time for parking in the Parking Facility. Such charges shall be payable to Landlord or such other entity as designated by Landlord, and shall be sent to the address Landlord designates from time to time. The initial charge for such parking spaces is $150.00 (including tax) per Non-Reserved parking pass, per month. Notwithstanding the foregoing to the con trary, during the period commencing on the date that Tenant takes possession of the Premises for the construction of the Initial Alterations and ending on the last day of the 7 th full calendar month of the Term, Tenant shall pay Landlord the sum of $75.00 (including tax) per Non-Reserved parking pass, per month. No deductions from the monthly charge shall be made for days on which the Parking Facility is not used by Tenant. Tenant may, from time to time request additional parking spaces, and if Landlord shall provide the same, such parking spaces shall be provided and used on a month-to-month basis, and otherwise on the foregoing terms and provisions, and at such prevailing monthly parking charges as shall be established from time to time.

3. Tenant shall at all times comply with all applicable ordinances, rules, regulations, codes, laws, statutes and requirements of all federal, state, county and municipal governmental bodies or their subdivisions respecting Tenant’s use of the Parking Facility. Landlord reserves the right to adopt, modify and enforce reasonable, non-discriminatory rules (“Rules”) governing the use of the Parking Facility from time to time including any key-card, sticker or other identification or entrance system and hours of operation, to the extent such R ules are not inconsistent with the express terms and conditions set forth in this Parking Agreement. The Rules set forth herein are currently in effect. Landlord may refuse to permit any person who habitually or repeatedly violates such Rules to park in the Parking Facility, and any violation of the Rules shall subject the car to removal from the Parking Facility.

4. Unless specified to the contrary above, the parking spaces hereunder shall be provided on a non-designated “first-come, first-served” basis. Subject to Section 13 of the Lease, Tenant acknowledges that Landlord has no liability for claims arising through acts or omissions of any independent operator of the Parking Facility. Subject to Section 13 of the Lease, Landlord shall have no liability whatsoever for any damage to items located in the Parking Facility, nor for any personal injuries or death arising out of any matter relating to the Parki ng Facility, and in all events, Tenant agrees to look first to its insurance carrier and to require that Tenant’s employees look first to their respective insurance carriers for payment of any losses sustained in connection with the use of the Parking Facility; provided, however, that subject to the waiver of subrogation set forth in Section 15 of the Lease, the foregoing shall not eliminate or reduce any liability Landlord may have pursuant to applicable Laws for personal injury and/or property damage which results from Landlord’s negligence or willful misconduct; provided further, however, that except to the extent of such negligence or willful misconduct by Landlord, Landlord shall not be liable for the acts of third parties (e.g., theft, vandalism, accidents and the like).Tenant hereby waives on behalf of its insurance carriers all rights of subrogation against Landlord or Landlord’s agents. Landlord

1

reserves the right to assign specific parking spaces, and to reserve parking spaces for visitors, small cars, handicapped persons and for other tenants, guests of tenants or other parties, which assignment and reservation or spaces may be relocated as reasonably determined by Landlord from time to time, and Tenant and persons designated by Tenant hereunder shall not park in any location designated for such assigned or reserved parking spaces. Tenant acknowledges that the Parking Facility may be closed entirely or in part in order to make repairs or perform maintenance services, or to alter, modify, re-stripe or renovate the Parking Facility, or if required by casualty, strike, condemnation, act of God, governmental law or requirement or other reason beyond the operator’s reasonable control. In such event, Landlord shall refund any prepaid parking rent hereunder, prorated on a per diem basi s, and Landlord shall use commercially reasonable efforts to minimize interference with Tenant’s business operations and to provide reasonable alternative parking for Tenant.

5. If Tenant shall default under this Parking Agreement (following reasonable notice to Tenant, except in an emergency and in connection with repeated failures, where no notice shall be required), the operator shall have the right to remove from the Parking Facility any vehicles hereunder which shall have been involved or shall have been owned or driven by parties involved in causing such default, without liability therefor whatsoever except to the extent provided for in Section 13 of the Lease. Any default by Tenant under the Lease shall be a default under thi s Parking Agreement, and any default under this Parking Agreement shall be a default under the Lease.

ASBESTOS NOTIFICATION

This Exhibit is attached to and made a part of the Lease by and between CA-10960 WILSHIRE LIMITED PARTNERSHIP, a Delaware limited partnership (“Landlord”) and BOINGO WIRELESS, INC., a Delaware corporation (“Tenant”) for space in the Building located at 10960 Wilshire Boulevard, Los Angeles, California.

Asbestos-containing materials (“ACMs”) were historically commonly used in the construction of commercial buildings across the country. ACMs were commonly used because of their beneficial qualities; ACMs are fire-resistant and provide good noise and temperature insulation.

Some common types of ACMs include surfacing materials (such as spray-on fireproofing, stucco, plaster and textured paint), flooring materials (such as vinyl floor tile and vinyl floor sheeting) and their associated mastics, carpet mastic, thermal system insulation (such as pipe or duct wrap, boiler wrap and cooling tower insulation), roofing materials, drywall, drywall joint tape and drywall joint compound, acoustic ceiling tiles, transite board, base cove and associated mastic, caulking, window glazing and fire doors. These materials are not required under law to be removed from any building (except prior to demolition and certain renovation projects). Moreover, ACMs generally are not thought to present a threat to human health unless they cause a release of asbestos fibers into the air, which does not typically occur unless (1) the ACMs are in a deteriorated condition, or (2) the ACMs have been significantly disturbed (such as through abrasive cleaning, or maintenance or renovation activities).

It is possible that some of the various types of ACMs noted above (or other types) are present at various locations in the Building. Anyone who finds any such materials in the Building should assume them to contain asbestos unless those materials are properly tested and found to be otherwise. In addition, under applicable Law, certain of these materials are required to be presumed to contain asbestos in the Building because the Building was built prior to 1981 (these materials are typically referred to as “Presumed Asbestos Containing Materials” or “PACM”). PACM consists of thermal system insulation and surfacing material found in buildings constructed prior to 1981, and asphalt or vinyl flooring installed prior to 1981. If any thermal system insulation, asphalt or vinyl flooring or surfacing materials are found to be present in the Building, such materials must be considered PACM unless properly tested and found otherwise. In addition, Landlord has identified the presence of certain ACMs in the Building. For information about the specific types and locations of these identified ACMs, please contact the Property Manager. The Property Manager maintains records of the Building’s asbestos information including any Building asbestos surveys, sampling and abatement reports. This information is maintained as part of Landlord’s asbestos Operations and Maintenance Plan (“O&M Plan”).

The O&M Plan is designed to minimize the potential of any harmful asbestos exposure to any person in the Building. Because Landlord is not a physician, scientist or industrial hygienist, Landlord has no special knowledge of the health impact of exposure to asbestos. Therefore, Landlord hired an independent environmental consulting firm to prepare the Building’s O&M Plan. The O&M Plan includes a schedule of actions to be taken in order to (1) maintain any building ACMs in good condition, and (2) to prevent any significant disturbance of such ACMs. Appropriate Landlord personnel receive regular periodic training on how to properly administer the O&M Plan.

The O&M Plan describes the risks associated with asbestos exposure and how to prevent such exposure. The O&M Plan describes those risks, in general, as follows: asbestos is not a significant health concern unless asbestos fibers are released and inhaled. If inhaled, asbestos fibers can accumulate in the lungs and, as exposure increases, the risk of disease (such as asbestosis and cancer) increases. However, measures to minimize exposure and consequently minimize the accumulation of fibers, reduce the risk of adverse health effects.

The O&M Plan also describes a number of activities which should be avoided in order to prevent a release of asbestos fibers. In particular, some of the activities which may present a health risk (because those activities may cause an airborne release of asbestos fibers) include moving, drilling, boring or otherwise disturbing ACMs. Consequently, such activities should not be attempted by any person not qualified to handle ACMs. In other words, the approval of Building management must be obtained prior to engaging in any such activities. Please contact the Property Manager for more information in this regard. A copy of the written O&M Plan for the Building is located in the Building Management Office and, upon your request, will be made available to tenants for you to review and copy during Building Service Hours.

Because of the presence of ACM in the Building, Landlord is also providing the following warning, which is commonly known as a California Proposition 65 warning:

1

WARNING: This Building contains asbestos, a chemical known to the State of California to cause cancer.

HVAC DESIGN SPECIFICATIONS

Landlord shall furnish heating and air conditioning to produce the following results effective under normal business operations and in the absence of the use of equipment atypical of general office use which affects the temperature which would otherwise be maintained in the Premises:

Landlord shall supply HVAC with a temperature of 56 F at the Base Building shaft and air at 1.75 CFM/USF with 20 CFM of outside air per person and a relative humidity of 40 to 55%. The heating and cooling system shall maintain 72 F +/- 2 based on the lowest typical winter temperatures and highest typical summer temperatures in the area.

The foregoing is based upon occupancy density in the Premises of not more than one (1) person per each one hundred (100) square feet of floor area and a maximum diversified electric lighting and office machine load of 5 watts per square foot of floor area of the Premises. Notwithstanding the foregoing, Landlord shall not be liable to Tenant for any failure to achieve or maintain the results set forth above to the extent that such failure is caused by Tenant’s use of heat generating machines, equipment or lighting any of which is atypical for a modern office and/or to the extent such failure is caused by an occupancy density or a maximum diversified electric lighting and office machine load beyond that set forth in this paragraph.

FORM OF LANDLORD’S LIEN RELEASE
(REGARDING THIRD PARTY EQUIPMENT LEASES)

THIS AGREEMENT is entered into as of , , by and between CA-10960 WILSHIRE LIMITED PARTNERSHIP, a Delaware limited partnership (“Landlord”), BOINGO WIRELESS, INC., a Delaware corporation (“Tenant”) and , a(n) &nbs p; (“Lender”), with reference to the following facts:

A. Landlord and Tenant have entered into a written lease dated April , 2007, as same may be amended from time to time (the “Lease”) for certain premises (the “Premises”) more fully described in the Lease located in that certain office building known as 10960 Wilshire (the “Building”) and located at 10960 Wilshire Boulevard, Los Angeles, California.

B. Tenant desires to borrow certain funds or obtain equipment financing or other financing from Lender (the “Loan”), and Lender desires to obtain a security interest in the Tenant’s personal property located within the Premises described in Exhibit A attached hereto (the “Collateral”) until such Loan is repaid.

C. Landlord is willing to subordinate its rights in the Collateral to the rights of Lender’s security interest upon the terms and conditions hereinafter set forth.

NOW, THEREFORE, in consideration of the premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. The only property affected by this Agreement is that Collateral specifically listed on Exhibit A attached hereto. Any property not described in Exhibit A shall not be subject to the terms of this Agreement and Landlord shall be entitled, to the extent provided by the Lease and by law, to exercise any lien, right or remedy against such other property.

2. Notwithstanding anything to the contrary contained in the Lease, until such time as Tenant repays in full to Lender the Loan which is secured by the Collateral, the Collateral shall remain the personal property of Tenant subject to the security interest of Lender. Lender shall notify Landlord when the obligations of Tenant to repay the Loan have been satisfied and discharged.

3. Landlord does hereby subordinate any and all claims or rights in and to the Collateral to the security interest of Lender in the Collateral; provided, however, that this subordination shall not prevent Landlord from exercising any right or remedy against Tenant to which Landlord may be entitled under the terms of the Lease or as may be provided by applicable law, nor shall it prevent Landlord from exercising any lien on any property of Tenant, including the Collateral, or enforcing any judgment by levying upon any property of Tenant, including the Collateral, so long a s Landlord recognizes Lender’s prior right to the Collateral.

4. Landlord hereby agrees that Lender may enter the Premises for the purpose of inspecting or removing the Collateral, but only if:

(a) permitted by Tenant. Tenant hereby consents to Lender’s entry into the Premises for purposes of inspecting or removing the Collateral;

(b) Lender gives Landlord at least 10 days prior written notice;

(c) Lender enters the Premises for purpose of removing the Collateral at such time and in such manner as Landlord reasonably may determine so as to minimize disruption to the operation of the Building, which period may include the sixty (60) day period immediately following the expiration or earlier termination of the Lease; and

(d) There shall be no display nor public nor private sale of the Collateral on the Premises or in the Building.

Lender and Tenant agree, jointly and severally, promptly to repair any damage to the Premises or to the Building caused by the removal of the Collateral or, if Landlord, in its sole discretion,

1

shall elect to make such repairs, to pay to Landlord upon demand the costs and expenses incurred in connection therewith.

Lender hereby indemnifies Landlord for any claim, liability or expense (including reasonable attorneys’ fees) arising out of or in connection with Lender’s removal of the Collateral and Lender’s entry and activities upon the Premises and the Building.

5. If Landlord shall fail to demand strict compliance with any provision hereof, such failure shall not constitute a waiver of any right or remedy to which Landlord may be entitled.

6. If Lender sells the Collateral to satisfy claims against Tenant, all funds derived from the sale of the Collateral, to the extent that such funds are in excess of the amount owed to the Lender, shall belong to Landlord, subject to the terms of the Lease, to satisfy any claim which Landlord may have.

7. This Agreement contains the entire understanding between the parties hereto. Any modification shall be effective only if in writing and signed by the parties hereto.

8. Any notice desired to be given to any other party hereunder shall be in writing and delivered by hand or sent by registered or certified mail with return receipt requested, or sent by overnight or same day commercial courier service at the party’s respective notice address(es) below. Each notice shall be deemed to have been received or given on the earlier to occur of (i) actual delivery or the date on which delivery is refused, if delivered by hand delivery, (ii) 3 days after notice is deposited in the U.S. mail, if delivered via certified mail, or (iii ) one business day after deposit with a commercial courier service. Either party may, at any time, change its notice address (other than to a post office box) by giving the other parties at least 10 days advance written notice of the new address in the manner described in this Section.

FORM OF RECOGNITION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT

This Recognition, Non-Disturbance and Attornment Agreement (this “Agreement”) is made as of , 2007, by and between CA-10960 WILSHIRE LIMITED PARTNERSHIP, a Delaware limited partnership (“Ground Lessor”), and BOINGO WIRELESS, INC., a Delaware corporation (“Tenant”).

R E C I T A L S :

WHEREAS, under a certain Ground Lease dated as of March 1, 1968 (as subsequently amended, the “Ground Lease”), Ground Lessor’s predecessor-in-interest (Pacific Lighting Properties, Inc., a California corporation), did lease, let, and demise the property (hereinafter called the “Property”) located at 10960 Wilshire Boulevard, Los Angeles, California, as described in the Ground Lease, to Tishman Westwood Corp., a California corporation (“Original Landlord”), as predecessor-in-interest to CA-10960 WILSHIRE LIMITED PARTNERSHIP, a Delaware limited partnership (“Landlord”), for the period of time and upon the covenants, terms, and conditions therein stated; and

WHEREAS, under a certain lease dated as of April , 2007 (hereinafter referred to as the “Lease”), Landlord did lease, let, and demise a portion of Premises (the “Premises”) to Tenant for the period of time and upon the covenants, terms, and conditions therein stated; and

WHEREAS, Ground Lessor has consented to the Lease; and

WHEREAS, as of the date hereof, Ground Lessor and Landlord are the same or affiliated entities, Ground Lessor being an entity controlled by, controlling or under common control with Landlord (as such, “Affiliates”); and

WHEREAS, Ground Lessor is willing to agree that in the event of a “Recognized Lease Termination,” as that term is defined in Section 1 of this Agreement, Tenant shall be entitled to remain in occupancy of the Premises upon the covenants, terms, and conditions set forth hereinbelow.

A G R E E M E N T :

NOW, THEREFORE, in consideration of the covenants, terms, conditions and agreements herein contained, and in consideration of other good and valuable consideration, each to the other, the sufficiency and receipt of which are hereby acknowledged, the parties hereto agree, covenant, and warrant as follows.

1. Upon the occurrence of a “Recognized Lease Termination,” as that term is defined, below, so long as the Lease is then in full force and effect and the original tenant named herein (the “Original Tenant”) or an affiliate of Original Tenant pursuant to the terms and conditions of Section 11.04 of such Lease (an “Affiliate”) is not in default thereunder, beyond any applicable notice and cure period set forth therein, Ground Lessor and Tenant hereby acknowledge and agree that (a) subject to the terms of this Agreement and the “Direct Lease,” as that term is defined, below, Ground Lessor shall not disturb Tenant’s possession of the Premises, and (b) the Lease shall immediately thereafter automatically be deemed a direct lease between Ground Lessor and T enant (a “Direct Lease”) upon all the terms and conditions (including, without limitation, the rent) set forth in the Lease as if Ground Lessor were the originally named Landlord, provided that, unless the same was assigned or otherwise transferred to Ground Lessor by Landlord (an assignment/transfer which shall be deemed to have occurred to the extent that Ground Lessor and Landlord are, at the time of any Recognized Lease Termination, Affiliates), Tenant shall deliver to Ground Lessor within ten (10) business days following written demand by Ground Lessor a security deposit in an amount equal to any “security deposit” or other security otherwise due under the Lease. In the event of a Recognized Lease Termination, Tenant shall continue to accept the Premises in its then-existing, as-is condition; provided, however, Tenant shall remain entitled to any unpaid tenant improvement allowance in connection with Tenant’s construction of its Initial Improvement pursuant to the te rms and conditions of Exhibit C attached to the Lease; provided further, however, that the foregoing shall in no way be deemed to alter or amend Ground Lessor’s ongoing obligations, if any, to repair, maintain and operate the Building pursuant to the terms of the Direct Lease (the “Ongoing LL Obligations”). In the event that Tenant shall be in default under the Lease (beyond any applicable notice and cure periods) at the time of a Recognized Lease Termination, Ground Lessor may, at its sole option, waive such default as a contingency to the foregoing

1

terms of this Section 1. For purposes of this Agreement, a “Recognized Lease Termination” shall mean (A) a termination of the Ground Lease due to a default by Landlord, or (B) a voluntary termination of the Ground Lease by mutual agreement of Ground Lessor and Landlord, or (C) the expiration of the existing term of the Ground Lease to the extent Landlord has not extended the term of the Ground Lease pursuant to the express terms and conditions thereof. The rights contained in this Agreement shall apply to the Original Tenant or its Affiliate only, and not any other assignee, sublessee or transferee of Original Tenant’s interest in the Lease.

2. Except with regard to events of casualty damage or condemnation, for which the express terms and conditions of Sections 16 and 17 of the Lease shall control, Tenant otherwise agrees that in the event of any act or omission by Landlord under the Lease which would give Tenant the right, either immediately or after a period of time, to terminate the Lease, whether or not set forth in the Lease, Tenant will not exercise any such right to terminate until (i) it shall have given written notice of the act or omission to Ground Lessor, and (ii) if the default by Landlord is of a nature which can be cured by the Ground Lessor, and if the Ground Lessor is proceeding with diligence to cure such default, Tenant shall have given the Ground Lessor the time periods set forth in the Lease for Ground Lessor’s cure of such default, in order to cure such default, provided that any such cure period shall not commence to run until Ground Lessor’s receipt of written notice from Tenant of such default.

3. Upon the creation of a Direct Lease in accordance with the terms thereof, Tenant will, subject to the term hereof, immediately thereafter make all payments due under the Lease directly to Ground Lessor.

4. Notwithstanding anything contained herein to the contrary, upon the creation of a Direct Lease in accordance with the terms hereof, Ground Lessor and its respective assignees shall not be:

(a) Liable for any act or omission of Landlord, or its successors or assigns, except to the extent (i) of any Ongoing LL Obligations, (ii) Ground Lessor and Landlord are, as of the date of the Recognized Lease Termination, Affiliates.

(b) Subject to any offsets or defenses which Tenant might have as to Landlord, or its successors or assigns, or to any claims for damages against Landlord, or its successors or assigns; provided, however, (i) Ground Lessor shall satisfy any unpaid tenant improvement allowance obligations in connection with Tenant’s construction of its Initial Improvement pursuant to the terms and conditions of Exhibit C attached to the Lease, (ii) Ground Lessor shall satisfy any Ongoing LL Obligations, and (iii) the restrictions set forth in this item (b), above, shall not apply to the extent Ground Lessor and Landlord are, as of the date of the Recognized Lease Termination, Affiliates.

(c) Required or obligated to credit Tenant with any rent or additional rent paid by Tenant to Landlord, except to the extent actually received by Ground Lessor from Landlord (actual receipt of which shall be deemed to have occurred to the extent that Ground Lessor and Landlord are, at the time of any Recognized Lease Termination, Affiliates).

(d) Unless the same was assigned or otherwise transferred to Ground Lessor by Landlord (an assignment/transfer which shall be deemed to have occurred to the extent that Ground Lessor and Landlord are, at the time of any Recognized Lease Termination, Affiliates), bound to or liable for refund of all or any part of any security deposit deposited by Tenant with Landlord.

(e) Liable to Tenant under the Lease.

(f) Liable to Tenant under the Lease in connection with any event or circumstance occurring prior to the commencement of the Direct Lease, except to the extent of any Ongoing LL Obligations.

5. Tenant covenants and agrees for the benefit and reliance of Ground Lessor that it will not, without the express written consent of Ground Lessor, cancel, terminate, modify, alter, amend or surrender the Lease, except as permitted by law and the express provisions of the Lease.

6. Ground Lessor and Tenant hereby agree as follows:

(a) Except as specifically set forth in this Agreement, that neither this Agreement, nor anything to the contrary in the aforesaid Lease or in any modifications or amendments thereto shall, prior to the creation of a Direct Lease in accordance with the terms hereof, operate to give rise to or create any liability of Ground Lessor to Tenant or give rise to or create direct contractual privity of any kind between Ground Lessor and Tenant. In connection with the foregoing, Ground Lessor, its

2

successors and assigns, shall be responsible to Tenant for performance of only those covenants and obligations of the Lease accruing after the creation of a Direct Lease as set forth herein (except to the extent of any Ongoing LL Obligations), and Ground Lessor’s obligations to Tenant shall be further limited as provided in the Lease and this Agreement, provided that the foregoing shall not be a waiver of any of Tenant’s rights under the Lease as to any events which occur prior to the creation of such Direct Lease in accordance with the terms hereof, and give rise to a default by Ground Lessor under the Lease after the creation of such Direct Lease in accordance with the terms hereof.

(b) Upon Ground Lessor’s written request of Tenant given at any time after the creation of a Direct Lease in accordance with the terms hereof, Tenant (as tenant) agrees to execute a lease of the Premises with Ground Lessor or its successor (as ground lessor) (the exact wording of which shall be negotiated by the parties in good faith) upon the terms and conditions set forth herein.

(c) Ground Lessor shall provide written notice to Tenant promptly upon the occurrence of a Recognized Lease Termination.

7. Any notices to Tenant or Ground Lessor hereunder shall be sent by United States certified or registered mail, postage prepaid, return receipt requested, by nationally recognized overnight courier or by personal delivery, addressed as follows:

or as to each party, to such other address as the party may designate by a notice given in accordance with the requirements contained in this Section 7.

9. This instrument may be executed in multiple counterparts, all of which shall be deemed originals and with the same effect as if all parties hereto had signed the same document.
