The parties hereto agree that the lease of the Premises is upon and subject to the terms, covenants and conditions herein set forth, and Tenant covenants as a material part of the consideration for this Lease to keep and perform each and all of such terms, covenants and conditions by it to be kept and performed and that this Lease is made upon the condition of such performance. The parties hereto hereby acknowledge that the purpose of Exhibit A is to show the approximate location of the Premises only, and such Exhibit is not meant to constitute an agreement, representation or warranty as to the construction of the Premises, the precise area thereof or the specific location of the “Common Areas,” as that term is defined in Section 1.1.3, below, or the elements thereof or of the accessways to the Premises or the “Project,” as that term is defined in Section 1.1.2, below. Except as specifically set forth in this Lease and in the Tenant Work Letter attached hereto as Exhibit B (the “Tenant Work Letter”), Landlord shall not be obligated to provide or pay for any improvement work or services related to the improvement of the Premises. Tenant also acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty regarding the condition of the Premises, the Building or the Project or with respect to the suitability of any of the foregoing for the conduct of Tenant’s business, except as specifically set forth in this Lease and the Tenant Work Letter. Subject to Landlord’s ongoing maintenance and repair obligations specifically set forth in this Lease and the terms and conditions of Section 1.2 of the Tenant Work Letter, and except for matters that could not reasonably be discovered by Tenant prior to taking possession of the Premises, the taking of possession of the Premises by Tenant shall conclusively establish that the Premises and the Building were at such time in good and sanitary order, condition and repair. Subject to applicable laws and the other provisions of this Lease, and except in the event of an emergency, Tenant shall have access to the Building, the Premises and the common areas of the Building, other than common areas requiring access with a Building engineer, twenty-four (24) hours per day, seven (7) days per week, every day of the year, including, without limitation, with respect to any loading area; provided, however, that Tenant shall only be permitted to have access to and use of the mailroom and other limited-access areas of the Building during the normal operating hours of such portions of the Building.

1.1.2. The Building and The Project. The Premises are a part of the building set forth in Section 2.1 of the Summary (the “Building”). The Building is part of an office/laboratory project described below. The term “Project,” as used in this Lease, shall mean (i) the Building and the Common Areas, (ii) the land (which is improved with landscaping, parking facilities and other improvements) upon which the Building and the Common Areas are located, and (iii) the office building located at ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇, and the land upon which such adjacent office/laboratory buildings are located, and (iv) at Landlord’s reasonable discretion, any additional real property, areas, land, buildings or other improvements added thereto which is owned by Landlord (or an affiliate of Landlord) and located adjacent to the Project.

1.1.3. Common Areas. Tenant shall have the non-exclusive right to use in common with other tenants in the Project, and subject to the rules and regulations referred to in Article 5 of this Lease, those portions of the Project which are provided, from time to time, for use in common by Landlord, Tenant and any other tenants of the Project (such areas, together with such other portions of the Project reasonably designated by Landlord, are collectively referred to herein as the “Common Areas”). The Common Areas shall consist of the “Project Common Areas” and the “Building Common Areas.” The term “Project Common Areas,” as used in this Lease, shall mean the portion of the Project designated as such by Landlord. The term “Building Common Areas,” as used in this Lease, shall mean the portions of the Common Areas located within the Building reasonably designated as such by Landlord. The manner in which the Common Areas are maintained and operated shall be at the sole discretion of Landlord (but shall at least be consistent with the manner in which the common areas of Comparable Buildings are maintained (provided that, except as otherwise expressly set forth in this Lease, in no event shall Landlord be required to improve or enhance the Common Areas in existence as of the date of this Lease)) and the use thereof shall be subject to such reasonable non-discriminatory rules, regulations and restrictions as Landlord may make from time to time; provided that Landlord shall not enforce such rules, regulations and restrictions in a discriminatory manner against Tenant as opposed to other tenants of the Project. Landlord reserves the right to close temporarily, make alterations or additions to, or change the location of elements of the Project and the Common Areas, provided that, in connection therewith, (i) Landlord shall perform such closures, alterations, additions or changes in a commercially reasonable manner and, in connection therewith, shall use commercially reasonable efforts to minimize any unreasonable interference with Tenant’s use of and/or access to the Premises for the Permitted Use and/or Tenant’s parking rights under this Lease (provided that to the extent Landlord provides Tenant with “Reasonable Alternate Parking,” as that term is defined in Section 19.5.2 below, then no unreasonable interference with Tenant’s parking rights shall be deemed to have occurred), and (ii) Landlord shall give Tenant at least five (5) business days prior notice if such closures, alterations, additions or changes will interfere with, or limit, on other than a non-material basis (except in the event of an emergency, where no prior notice shall be required, except that Landlord shall nonetheless use commercially reasonable efforts to notify Tenant): (a) Tenant’s access to or from the Premises, (b) Tenant’s use of the Premises for the Permitted Use, or (c) Tenant’s parking passes, Tenant’s signage rights specifically set forth in Article 23 below or Tenant’s rooftop rights specifically set forth in Section 29.32 below.

1.1.3.1. Fitness Facility. Landlord shall construct a fitness facility the “Fitness Facility”) as part of the Building Common Areas; provided that the location, specifications and all other aspects of the Fitness Facility (including, without limitation, the construction thereof) shall be determined by Landlord in its sole discretion; provided further that the use of the Fitness Facility by the tenants of the Project, when constructed, shall be subject to reasonable and non-discriminatory rules and regulations promulgated from time to time by Landlord in connection with such fitness facility. Subject to Force Majeure (as that term is defined in Section 29.16 below), Landlord’s temporary closure of the Fitness Facility to repair, improve or maintain the same, and/or any closure of the Fitness Facility caused by an act or omission of Tenant, the hours of operation of the Fitness Facility shall be at least 8:00 a.m. to 6:00 p.m. Monday through Friday, excluding Holidays (as that term is defined in Section 6.1.1 below). Notwithstanding anything to the contrary in this Lease, if, following the date (the “Fitness Facility Outside Date”) which occurs four (4) months following the date upon which the Premises is Ready for Occupancy (provided that the Fitness Facility Outside Date shall be delayed on a day-

6

for-day basis for each day that the substantial completion of the Fitness Facility (subject to punch list items) is delayed by an act or omission of Tenant or Force Majeure), either (i) Landlord has failed to substantially complete the Fitness Facility (subject to punch list items) or (ii) Tenant is prevented from accessing the Fitness Facility between 4:00 a.m. to 10:00 p.m. Monday through Friday, excluding Holidays (provided that such prevention of access is not the result of (A) Force Majeure, (B) Landlord’s temporary closure (which temporary closure shall not exceed an aggregate of fifteen (15) consecutive business days) of the Fitness Facility to repair, improve or maintain the same, and/or (C) any closure of the Fitness Facility caused by an act or omission of Tenant) (any such set of circumstances as set forth in items (i) or (ii), above, to be known as a “Fitness Facility Abatement Event”), then Tenant shall give Landlord notice of such Fitness Abatement Event (provided that in no event shall Tenant delivery such notice prior to the Fitness Facility Outside Date, as the same may be delayed pursuant to this Section 1.1.3.1 above), and if such Fitness Abatement Event continues for five (5) consecutive business days after Landlord’s receipt of any such notice (the “Fitness Facility Eligibility Period”), then the Base Rent payable by Tenant under this Lease shall be reduced by an amount equal to Two Hundred and 00/100 Dollars ($200.00) per day during each day that such Fitness Facility Abatement Event continues to occur following the expiration of the Fitness Facility Eligibility Period. Such right to reduce Base Rent shall be Tenant’s sole and exclusive remedy for rent abatement or rent reduction at law or in equity for a Fitness Facility Abatement Event. At any time during the Lease Term, Landlord may deliver to Tenant a notice that sets forth the date upon which the Fitness Facility is substantially complete (subject to punch list items), which Tenant shall execute and return to Landlord within ten (10) days of receipt thereof, provided that if such notice is not factually correct, then Tenant shall make such changes as are necessary to make such notice factually correct and shall thereafter return such notice to Landlord within said ten (10) day period.

1.1.4. ▇▇▇▇▇▇ ▇▇▇▇▇ Amenities. Landlord and Ten ant hereby acknowledge that an affiliate of Landlord constructed a fitness center, a café, and a shared executive conference/training facility (collectively, the “▇▇▇▇▇▇ ▇▇▇▇▇ Amenities”) in that certain building located at ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ (the “▇▇▇▇▇▇ ▇▇▇▇▇ Building”), and, provided that Landlord or an affiliate of Landlord continues to own the ▇▇▇▇▇▇ ▇▇▇▇▇ Building, Tenant and Tenant’s employees shall have access to any such ▇▇▇▇▇▇ ▇▇▇▇▇ Amenities to the same extent as the similarly situated tenants of the Building and/or the ▇▇▇▇▇▇ ▇▇▇▇▇ Building.

1.2. Rentable Square Feet of Premises. The rentable square footage of the Premises is hereby deemed to be as set forth in Section 2.2 of the Summary, and shall not be subject to measurement or adjustment during the Lease Term.

1.3. Right of First Refusal. Commencing on the date (the “ROFR Effective Date”) which occurs six (6) months following the Lease Commencement Date, Landlord hereby grants to the Tenant originally named herein (the “Original Tenant”) and any Permitted Transferee Assignee (as that term is defined in Section 14.8 below) a one-time right of first refusal with respect to any space in the Building not included in the initial Premises (“First Refusal Space”). Notwithstanding the foregoing, such right of first refusal shall commence with respect to any particular applicable First Refusal Space only following the expiration or earlier termination of any leases which are existing as of the ROFR Effective Date of such First Refusal Space (or portion thereof) (including renewals of any such lease, irrespective of whether any such renewal is currently set forth in such lease or is subsequently granted or agreed upon, and regardless of

7

whether such renewal is consummated pursuant to a lease amendment or a new lease). Such right of first refusal shall be subordinate to all rights of other tenants of the Project, which rights relate to the First Refusal Space and are set forth in leases of space in the Project existing as of the date hereof, including, without limitation, any expansion, first offer, first refusal, first negotiation and other rights, regardless of whether such rights are executed strictly in accordance with their respective terms or pursuant to a lease amendment or a new lease (the “First Refusal Superior Rights”). Notwithstanding any contrary provision in the lease of any First Refusal Superior Right Holder, such rights of any First Refusal Superior Right Holder shall continue to be First Refusal Superior Rights in the event that such First Refusal Superior Right Holder’s lease is renewed or otherwise modified (and irrespective of whether any such renewal is currently set forth in such lease or is subsequently granted or agreed upon, and regardless of whether such renewal is consummated pursuant to a lease amendment or a new lease). All such tenants of the First Refusal Space as of the ROFR Effective Date and all such third party tenants in the Project holding First Refusal Superior Rights, are collectively referred to as the “First Refusal Superior Right Holders”.

1.3.1. Procedure for Offer. Subject to the terms hereof, commencing on the ROFR Effective Date, Landlord shall notify Tenant (the “First Refusal Notice”) when and if Landlord receives a “bona-fide third-party offer” for the First Refusal Space (or any portion thereof). Pursuant to such First Refusal Notice, Landlord shall offer to lease to Tenant such Refusal Space. The First Refusal Notice shall describe the space so offered to Tenant and shall set forth all the “Economic Terms,” as that term is defined in Section 1.3.2, below, applicable to the First Refusal Space. For the avoidance of doubt, Landlord shall have no obligation to deliver a First Refusal Notice to Tenant with respect to any bona-fide third party offer first received by Landlord prior to the ROFR Effective Date. For purposes of this Section 1.4, a “bona-fide third-party offer” shall mean a counter-offer received by Landlord to lease the Refusal Space from a qualified and unaffiliated third party which Landlord would otherwise be willing to accept (but for Tenant’s or any other First Refusal Superior Right Holder’s rights) or an offer made by Landlord to a qualified and unaffiliated third party (subject to Tenant’s and any other First Refusal Superior Right Holder’s rights) which the third party is willing to accept. For purposes of example only, but not by way of limitation, the following would each constitute a bone-fide third-party offer:

1.3.1.1. Landlord receives a request for proposal from a qualified third party. Landlord responds to the request for proposal with a lease proposal and subsequently receives a written bona-fide counter proposal from the qualified third party.

1.3.1.2. Landlord receives a written offer to lease from a qualified third party. Landlord responds to the offer with a written counter-offer and subsequently receives a bona-fide counter to Landlord’s counteroffer from the qualified third party.

1.3.2. Procedure for Acceptance. If Tenant wishes to exercise Tenant’s right of first refusal with respect to the First Refusal Space described in the First Refusal Notice, then within five (5) business days after delivery of the First Refusal Notice to Tenant, Tenant shall deliver notice (an “Election Notice”) to Landlord of Tenant’s irrevocable exercise of its right of first refusal with respect to all of the First Refusal Space described in the First Refusal Notice on the Economic Terms provided for therein. If Tenant does not so notify Landlord within such five (5) business day period of Tenant’s exercise of its first refusal right, then Landlord shall be free to

8

negotiate and enter into a lease for the First Refusal Space to anyone whom Landlord desires on any terms Landlord desires; provided, however, prior to leasing such First Refusal Space to any third party at a rental (taking into consideration the Economic Terms, calculated on a “Net Equivalent Lease Rate” basis pursuant to the process set forth below), which is less than ninety percent (90%) of the Net Equivalent Lease Rate of the Economic Term set forth in Landlord’s most recent First Refusal Notice for such First Refusal Space, Landlord shall first again offer such First Refusal Space to Tenant on the Economic Terms offered to such third-party tenant by delivering another First Refusal Notice to Tenant, which shall be subject to all of the terms and conditions of this Section 1.3.2, except Tenant shall have three (3) business days (instead of five (5) business days) after delivery of a second First Refusal Notice to exercise Tenant’s right to lease such First Offer Space. For purposes hereof, the “Economic Terms” shall mean the following items: (i) base rent and free rent, including escalations thereto, expressed as a dollar amount per rentable square foot, (ii) operating expense and tax protection such as a base year or expense stop (if any), and (iii) all other monetary concessions (e.g., free rent, improvement allowances). Notwithstanding anything to the contrary contained herein, Tenant must elect to exercise its right of first Refusal, if at all, with respect to all of the space offered by Landlord to Tenant at any particular time, and Tenant may not elect to lease only a portion thereof. The “Net Equivalent Lease Rate” for the Economic Terms shall be determined using the following steps.

1.3.2.1. The contractual rent payments for set forth in the Economic Terms should be arrayed monthly over the term of the First Refusal Space.

1.3.2.2. Any free rent or similar inducements received over time should be deducted in the time period in which they occur, resulting in the net cash flow arrayed over the term of the First Refusal Space.

1.3.2.3. The resultant net cash flow from the First Refusal Space should be then discounted (using an 8% annual discount rate) to the First Refusal Commencement Date (as that term is defined in Section 1.3.4 below), resulting in a net present value estimate.

1.3.2.4. From the net present value, up front inducements (improvements allowances and other concessions) should be deducted. These items should be deducted directly, on a “dollar for dollar” basis, without discounting since they are typically incurred at lease commencement, while rent (which is discounted) is a future receipt.

1.3.2.5. The net present value should then amortized back over the term of the First Refusal Space as a level monthly net rent payment using the same annual discount rate of 8.0% used in the present value analysis. This calculation will result in a hypothetical level or even payment over the term of the First Refusal Space.

1.3.3. Construction of First Refusal Space. Subject to the Economic Terms provided to Tenant for the First Refusal Space, Tenant shall take the First Refusal Space in its “as is” condition, and Landlord shall not be obligated to provide or pay for any improvement of the First Refusal Space. For the avoidance of doubt, if the Economic Terms include a tenant improvement allowance, Tenant shall receive the same allowance.

9

1.3.4. Lease of First Refusal Space. If Tenant timely exercises Tenant’s right of first refusal to lease First Refusal Space as set forth herein, Landlord and Tenant shall within thirty (30) days thereafter enter an amendment to this Lease (the “First Refusal Space Amendment”) for such First Refusal Space pursuant to this Section 1.3. Tenant’s lease of such First Refusal Space shall be upon the express terms set forth in the First Refusal Notice, but otherwise upon the same general terms and conditions set forth in this Lease and this Section 1.3. The First Refusal Space Amendment shall not contain the rights set forth in Section 2.2, below, unless such rights were set forth in the First Refusal Notice. The term of Tenant’s lease of the First Refusal Space shall commence on the date set forth in the First Refusal Notice (the “First Refusal Commencement Date”), and terminate on the date set forth in the First Refusal Notice.

1.3.5. Termination of Right of First Refusal. The rights contained in this Section 1.3 shall be personal to the Original Tenant and any Permitted Transferee Assignee, and may only be exercised by the Original Tenant and such Permitted Transferee Assignee (and not any other assignee, sublessee or other transferee of the Original Tenant’s interest in this Lease) if the Original Tenant or such Permitted Transferee Assignee occupies the entire Premises as of the date of the attempted exercise of the right of first refusal by Tenant. The right of first refusal granted herein shall terminate (i) with respect to any particular First Refusal Space upon the failure by Tenant to exercise its right of first refusal with respect to the First Refusal Space so offered by Landlord pursuant to the terms of this Section 1.3. Tenant shall not have the right to lease any First Refusal Space pursuant to the terms of this Section 1.3 in the event that less than two (2) years remains prior to the Lease Expiration Date; provided, however, to the extent Tenant then has an unexpired Lease Term renewal option pursuant to Section 2.2 of this Lease, Tenant shall have the right to irrevocably exercise such renewal option simultaneously with Tenant’s exercise of its first refusal right hereunder in order to cause the Lease Expiration Date to occur more than two (2) years following the First Refusal Commencement Date. Tenant shall not have the right to lease First Refusal Space, as provided in this Section 1.3, if, as of the date of the attempted exercise of any right of first refusal by Tenant, or, as of the scheduled date of delivery of such First Refusal Space to Tenant, Tenant is in default under this Lease beyond the applicable notice and cure period provided in this Lease or Tenant has previously been in default under this Lease (beyond any applicable notice and cure periods) more than once during the prior twelve (12) month period.

2. LEASE TERM; OPTION TERM.

2.1. Lease Term. The terms and provisions of this Lease shall be effective as of the date of this Lease. The term of this Lease (the “Lease Term”) shall be as set forth in Section 3.1 of the Summary, shall commence on the date set forth in Section 3.2 of the Summary (the “Lease Commencement Date”), and shall terminate on the date set forth in Section 3.3 of the Summary (the “Lease Expiration Date”) unless this Lease is sooner terminated as hereinafter provided. For purposes of this Lease, the term “Lease Year” shall mean each consecutive twelve (12) month period during the Lease Term; provided, however, that the first (1^st) Lease Year shall commence on the Lease Commencement Date and end on the last day of the month in which the first anniversary of the Lease Commencement Date occurs (or if the Lease Commencement Date is the first (1^st) day of a calendar month, then the first (1^st) Lease Year shall commence on the Lease Commencement Date and end on the day immediately preceding the first (1^st) anniversary of the Lease Commencement Date), and further provided that the last Lease Year shall end on the Lease Expiration Date. At any time during the Lease Term, Landlord may deliver to Tenant a notice in

10

the form as set forth in Exhibit C, attached hereto, as a confirmation only of the information set forth therein, which Tenant shall execute and return to Landlord within ten (10) days of receipt thereof, provided that if such notice is not factually correct, then Tenant shall make such changes as are necessary to make such notice factually correct and shall thereafter return such notice to Landlord within said ten (10) day period.

2.2. Option Term.

2.2.1. Option Right. Subject to the remaining terms of this Section 2.2, Landlord hereby grants to the Original Tenant and any Permitted Transferee Assignee one (1) option to extend the Lease Term for a period of five (5) years (the “Option Term”), which option shall be irrevocably exercised only by written notice delivered by Tenant to Landlord not earlier than twelve (12) months before the commencement of the Option Term and not later than nine (9) months before the commencement of the Option Term, provided that the following conditions (the “Option Conditions”) are satisfied: (i) as of the date of delivery of such notice, Tenant is not in monetary or other material default under this Lease beyond any applicable notice and cure period expressly set forth in this Lease; and (ii) as of the end of the Lease Term, Tenant is not in monetary or other material default under this Lease; (iii) Tenant has not previously been in monetary or other material default under this Lease (beyond any applicable notice and cure period expressly set forth in this Lease) more than twice; and (iv) the Lease then remains in full force and effect and the Original Tenant or any Permitted Transferee Assignee occupies at least fifty percent (50%) of the entire Premises at the time the option to extend is exercised and as of the commencement of the Option Term. beyond any applicable notice and cure period expressly set forth in this Lease. Landlord may, at Landlord’s option, exercised in Landlord’s sole and absolute discretion, waive any of the Option Conditions in which case the option, if otherwise properly exercised by Tenant, shall remain in full force and effect. Upon the proper exercise of such option to extend, and provided that Tenant satisfies all of the Option Conditions (except those, if any, which are waived by Landlord), the Lease Term, as it applies to the Premises, shall be extended for a period of five (5) years. The rights contained in this Section 2.2 shall be personal to Original Tenant or its Permitted Transferee Assignee and may be exercised by Original Tenant or its Permitted Transferee Assignee only (and not by any other assignee, sublessee or other “Transferee,” as that term is defined in Section 14.1 of this Lease, of Tenant’s interest in this Lease).

2.2.2. Option Base Rent. The annual Base Rent (as that term is defined in Section 3.1 below) payable by Tenant during the Option Term (the “Option Rent”) shall be equal to the “Fair Rental Value,” as that term is defined below, for the Premises as of the commencement date of the Option Term; provided, however, the Option Rent, on an average annual, effective (including free rent, if applicable, on a straight line basis) basis, for each Lease Year during the Option Term shall not be lower than the one hundred three percent (103%) of the annual Base Rent in effect immediately prior to the commencement of the Option Term. The “Fair Rental Value,” as used in this Lease, shall be equal to the annual base rent per rentable square foot (considering additional rent and any “base year” or “expense stop” applicable thereto), including all escalations, at which tenants (pursuant to leases consummated within the twelve (12) month period preceding the first day of the Option Term), are leasing non-sublease, non-encumbered, non-equity space which is not significantly greater or smaller in size than the subject space, for a comparable lease term, in an arm’s length transaction, which comparable space is located in the “Comparable Buildings,” as that term is defined in this Section 2.2.2, below (transactions satisfying the

11

foregoing criteria shall be known as the “Comparable Transactions”), 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 taking into account the value, if any, of the existing improvements in the subject space, such value to be based upon the age, condition, design, quality of finishes and layout of the improvements and the extent to which the same can be utilized by a general office user other than Tenant; and (c) other reasonable monetary concessions being granted such tenants in connection with such comparable space; provided, however, that in calculating the Fair Rental Value, no consideration shall be given to 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 spaces. The Fair Rental Value shall additionally include a determination as to whether, and if so to what extent, Tenant must provide Landlord with financial security, such as a letter of credit or guaranty, for Tenant’s Rent obligations in connection with Tenant’s lease of the Premises during the Option Term. Such determination shall be made by reviewing the extent of financial security then generally being imposed in Comparable Transactions from tenants of comparable financial condition and credit history to the then existing financial condition and credit history of Tenant (with appropriate adjustments to account for differences in the then-existing financial condition of Tenant and such other tenants). In addition, in connection with the determination of the Fair Rental Value, the age (based on the date of original construction or the latest major renovation) and location of any Comparable Building used in connection therewith shall be a factor in determining the Fair Rental Value. The Concessions (A) shall be reflected in the effective rental rate (which effective rental rate shall take into consideration the total dollar value of such Concessions as amortized on a straight-line basis over the applicable term of the Comparable Transaction (in which case such Concessions evidenced in the effective rental rate shall not be granted to Tenant)) payable by Tenant, or (B) at Landlord’s election, all such Concessions shall be granted to Tenant in kind. If there are not a sufficient number of Comparable Transactions to reasonably determine the Fair Rental Value, then the definition of Comparable Transactions shall be expanded to include smaller or larger transactions, provided that appropriate adjustments shall be made to such additional Comparable Transactions, as is necessary, given the size of such transactions. The term “Comparable Buildings” shall mean the Building and those other first-class life science buildings located in the ▇▇▇▇▇▇ ▇▇▇▇▇ area of San Diego, California. Notwithstanding the foregoing, during the Option Term, the Option Rent shall increase by three percent (3%) per annum on each anniversary of the first (1^st) day of the Option Term; provided that such annual increases shall be taken into consideration in connection with the determination of Fair Rental Value.

2.2.3. Determination of Option Rent. Notwithstanding any provision to the contrary contained herein, within fifteen (15) business days following Landlord’s receipt of written request from Tenant (which request shall not be delivered earlier than fifteen (15) months prior to the commencement of the Option Term nor later than ten (10) months prior to the commencement of the Option Term), Landlord shall provide Tenant with Landlord’s nonbinding good faith estimate of the Fair Rental Value for the Premises during the Option Term. In the event Tenant timely and appropriately exercises an option to extend the Lease Term, Landlord shall notify Tenant of Landlord’s determination of the Option Rent on or before the date which occurs six (6) months prior to the Lease Expiration Date. If Tenant, on or before the date which is thirty (30) days following the date upon which Tenant receives Landlord’s determination of the Option Rent, in good faith objects to Landlord’s determination of the Option Rent, then Landlord and Tenant

12

shall attempt to agree upon the Option Rent using their best good-faith efforts. If Landlord and Tenant fail to reach agreement within thirty (30) days following Tenant’s objection to the Option Rent (the “Outside Agreement Date”), then each party shall make a separate determination of the Option Rent, as the case maybe, within five (5) days, and such determinations shall be submitted to arbitration in accordance with Sections 2.2.3.1 through 2.2.3.7, below. If Tenant fails to object to Landlord’s determination of the Option Rent within the time period set forth herein, then Tenant shall be deemed to have accepted Landlord’s determination of Option Rent.

2.2.3.1. Landlord and Tenant shall each appoint one arbitrator who shall be, at the option of the appointing party, a real estate broker, appraiser or attorney who shall have been active over the five (5) year period ending on the date of such appointment in the leasing or appraisal, as the case may be, of commercial office properties in North San Diego, California. The determination of the arbitrators shall be limited solely to the issue of whether Landlord’s or Tenant’s submitted Option Rent is the closest to the actual Option Rent, taking into account the requirements of Section 2.2.2 of this Lease, as determined by the arbitrators. Each such arbitrator shall be appointed within fifteen (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. The arbitrators so selected by Landlord and Tenant shall be deemed “Advocate Arbitrators.”

2.2.3.2. The two (2) Advocate Arbitrators so appointed shall be specifically required pursuant to an engagement letter within ten (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 neither the Landlord or Tenant or either parties’ Advocate Arbitrator may, directly or indirectly, consult with the Neutral Arbitrator prior or subsequent to his or her appearance. The Neutral Arbitrator shall be retained via an engagement letter jointly prepared by Landlord’s counsel and Tenant’s counsel.

2.2.3.3. The three arbitrators shall, within thirty (30) days of the appointment of the Neutral Arbitrator, reach a decision as to whether the parties shall use Landlord’s or Tenant’s submitted Option Rent, and shall notify Landlord and Tenant thereof.

2.2.3.4. The decision of the majority of the three arbitrators shall be binding upon Landlord and Tenant.

2.2.3.5. If either Landlord or Tenant fails to appoint an Advocate Arbitrator within fifteen (15) days after the Outside Agreement Date, then the single Advocate Arbitrator appointed shall be deemed the Neutral Arbitrator.

2.2.3.6. If the two (2) Advocate Arbitrators fail to agree upon and appoint the Neutral Arbitrator, then either party may petition the presiding judge of the Superior Court of San Diego County to appoint the Neutral Arbitrator, subject to criteria in Section 2.2.3.2 of this Lease, or if he or she refuses to act, either party may petition any judge having jurisdiction over the parties to appoint such arbitrator.

13

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

2.2.3.8. In the event that the Option Rent shall not have been determined pursuant to the terms hereof prior to the commencement of the Option Term, Tenant shall be required to pay the Option Rent initially provided by Landlord to Tenant, and upon the final determination of the Option Rent, the payments made by Tenant shall be reconciled with the actual amounts of Option Rent due, and the appropriate party shall make any corresponding payment to the other party.

3. BASE RENT.

3.1. In General. Tenant shall pay, without prior notice or demand, at Tenant’s election either (a) by ACH Transfer (pursuant to transfer instructions provided by Landlord upon request from Tenant), or (b) to Landlord or Landlord’s agent (i) at the management office of the Project, or, (ii) at Landlord’s option, at such other place as Landlord may from time to time designate in writing, by a check for currency which, at the time of payment, is legal tender for private or public debts in the United States of America, base rent (“Base Rent”) as set forth in Section 4 of the Summary, payable in equal monthly installments as set forth in Section 4 of the Summary in advance on or before the first day of each and every calendar month during the Lease Term, without any setoff or deduction whatsoever. The Base Rent and Tenant’s Share of the Estimate Direct Expenses (as that term is defined in Section 4.4.2 below) for the first full month of the Lease Term, in an aggregate amount equal to $78,718.50, shall be paid at the time of Tenant’s execution of this Lease. If any Rent payment date (including the Lease Commencement Date) falls on a day of the month other than the first day of such month or if any payment of Rent is for a period which is shorter than one month, the Rent for any fractional month shall accrue on a daily basis for the period from the date such payment is due to the end of such calendar month or to the end of the Lease Term at a rate per day which is equal to 1/365 of the applicable annual Rent. All other payments or adjustments required to be made under the terms of this Lease that require proration on a time basis shall be prorated on the same basis.

3.2. Abated Base Rent. Provided that Tenant is not then in default of this Lease (beyond all applicable notice and cure periods), then during the three (3) month period commencing on the first day of the second (2^nd) full calendar month of the Lease Term and continuing through and including the last day of the fourth (4^th) full calendar month of the Lease Term (the “Base Rent Abatement Period”), Tenant shall not be obligated to pay any Base Rent otherwise attributable to the Premises during such Base Rent Abatement Period (the “Base Rent Abatement”), subject to Section 2.2 of the Tenant Work Letter. Landlord and Tenant acknowledge that the aggregate amount of the Base Rent Abatement equals One Hundred Ninety-Nine Thousand Nine Hundred Twenty and 00/100 Dollars ($199,920.00). Tenant acknowledges and agrees that the foregoing Base Rent Abatement has been granted to Tenant as additional consideration for entering into this Lease, and for agreeing to pay the rental and performing the terms and conditions otherwise required under this Lease. If Tenant shall be in default under this Lease during the Base Rent Abatement Period, and shall fail to cure such default within the notice and cure period, if any, permitted for cure pursuant to terms and conditions of this Lease, or if this Lease is terminated for any reason other than Landlord’s breach of this Lease, then the dollar amount of the unapplied portion of the Base Rent Abatement as of the date of such default or termination, as the case may be, shall be converted to a credit to be applied to the Base Rent applicable at the end of the Lease Term and Tenant shall immediately be obligated to begin paying Base Rent for the Premises in full.

In addition to paying the Base Rent specified in Article 3 of this Lease, Tenant shall pay “Tenant’s Share” of the annual “Direct Expenses,” as those terms are defined in Sections 4.2.6 and 4.2.2 of this Lease, respectively. Such payments by Tenant, together with any and all other amounts payable by Tenant to Landlord pursuant to the terms of this Lease, are hereinafter collectively referred to as the “Additional Rent”, and the Base Rent and the Additional Rent are herein collectively referred to as “Rent.” All amounts due under this Article 4 as Additional Rent shall be payable for the same periods and in the same manner as the Base Rent.

Tax Expenses shall include, without limitation: (i) Any tax on the rent, right to rent or other income from the Project, or any portion thereof, or as against the business of leasing the Project, or any portion thereof; (ii) Any assessment, tax, fee, levy or charge in addition to, or in substitution, partially or totally, of any assessment, tax, fee, levy or charge previously included within the definition of real property tax; (iii) Any assessment, tax, fee, levy, or charge allocable to or measured by the area of the Premises or the Rent payable hereunder, including, without limitation, any business or gross income tax or excise tax with respect to the receipt of such rent, or upon or with respect to the possession, leasing, operating, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises, or any portion thereof; and (iv) Any assessment, tax, fee, levy or charge, upon this transaction or any document to which Tenant is a party, creating or transferring an interest or an estate in the Premises or the improvements thereon.

Tax refunds shall be credited against Tax Expenses and refunded to Tenant regardless of when received, based on the Expense Year to which the refund is applicable, provided that in no event shall the amount to be refunded to Tenant for any such Expense Year exceed the total amount paid by Tenant as Additional Rent under this Article 4 for such Expense Year. If Tax Expenses for any period during the Lease Term or any extension thereof are increased after payment thereof for any reason, including, without limitation, error or reassessment by applicable governmental or municipal authorities, Tenant shall pay Landlord upon demand Tenant’s Share of any such increased Tax Expenses. Notwithstanding anything to the contrary contained in this Section 4.2.5, there shall be excluded from Tax Expenses (i) all excess profits taxes, franchise taxes, documentary transfer taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate 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 Project), (ii) any items included as Operating Expenses, and (iii) any items paid by Tenant under Section 4.5 of this Lease.

4.2.6. “Tenant’s Share” shall mean the percentage set forth in Section 6 of the Summary.

4.3. Allocation of Direct Expenses.

4.3.1. Method of Allocation. The parties acknowledge that the Building is a part of a multi-building project and that the costs and expenses incurred in connection with the Project (i.e., the Direct Expenses) should be shared between the Building and the other buildings in the Project. Accordingly, as set forth in Section 4.2 above, Direct Expenses (which consist of Operating Expenses and tax Expenses) are determined annually for the Project as a whole, and a portion of the Direct Expenses, which portion shall be determined by Landlord on an equitable basis, shall be allocated to the Building (as opposed to other buildings in the Project). Such portion of Direct Expenses allocated to the Building shall include all Direct Expenses attributable solely to the Building and an equitable portion of the Direct Expenses attributable to the Project as a whole, and shall not include Direct Expenses attributable solely to other buildings in the Project.

4.3.2. Cost Pools. Landlord shall have the right, from time to time, to equitably allocate some or all of the Direct Expenses for the Project among different portions or occupants of the Project (the “Cost Pools”), in Landlord’s commercially reasonable discretion. Such Cost Pools may include, but shall not be limited to, the office space tenants of the Building or another building of the Project or of the Project, and the retail space tenants of the Building or another building of the Project or of the Project. The Direct Expenses within each such Cost Pool shall be allocated and charged to the tenants within such Cost Pool in a reasonable and equitable manner.

4.4. Calculation and Payment of Additional Rent. Tenant shall pay to Landlord, in the manner set forth in Section 4.4.1, below, and as Additional Rent, Tenant’s Share of Direct Expenses for each Expense Year.

4.4.1. Statement of Actual Direct Expenses and Payment by Tenant. Landlord shall endeavor to give to Tenant within 150 days following the end of each Expense Year, a

20

statement (the “Statement”) which shall state the Direct Expenses incurred or accrued for such preceding Expense Year, and which shall indicate the amount of Tenant’s Share of Direct Expenses. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, Tenant shall pay, with its next installment of Base Rent due, the full amount of Tenant’s Share of Direct Expenses for such Expense Year, less the amounts, if any, paid during such Expense Year as “Estimated Direct Expenses,” as that term is defined in Section 4.4.2, below, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses, Tenant shall receive a credit in the amount of Tenant’s overpayment against Rent next due under this Lease. The failure of Landlord to timely furnish the Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing its rights under this Article 4. Even though the Lease Term has expired and Tenant has vacated the Premises, when the final determination is made of Tenant’s Share of Direct Expenses for the Expense Year in which this Lease terminates, Tenant shall immediately pay to Landlord such amount, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses, Landlord shall, within thirty (30) days, deliver a check payable to Tenant in the amount of the overpayment. The provisions of this Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term. Notwithstanding the immediately preceding sentence, Tenant shall not be responsible for Tenant’s Share of any Direct Expenses attributable to any Expense Year which are first billed to Tenant more than two (2) calendar years after the Lease Expiration Date.

4.4.2. Statement of Estimated Direct Expenses. In addition, Landlord shall endeavor to give Tenant a yearly expense estimate statement (the “Estimate Statement”) which shall set forth Landlord’s reasonable estimate (the “Estimate”) of what the total amount of Direct Expenses for the then-current Expense Year shall be and the estimated Tenant’s Share of Direct Expenses (the “Estimated Direct Expenses”). The failure of Landlord to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Estimated Direct Expenses under this Article 4, nor shall Landlord be prohibited from revising any Estimate Statement or Estimated Direct Expenses theretofore delivered to the extent necessary. Thereafter, Tenant shall pay, with its next installment of Base Rent due (provided Tenant has received at least thirty (30) days’ notice of the Estimated Direct Expenses), a fraction of the Estimated Direct Expenses for the then-current Expense Year (reduced by any amounts paid pursuant to the last sentence of this Section 4.4.2). Such fraction shall have as its numerator the number of months which have elapsed in such current Expense Year, including the month of such payment, and twelve (12) as its denominator. Until a new Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time, provided no more than twice in any Lease Year), Tenant shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Direct Expenses set forth in the previous Estimate Statement delivered by Landlord to Tenant.

4.5. Taxes and Other Charges for Which Tenant Is Directly Responsible. Tenant shall be liable for and shall pay ten (10) days before delinquency, taxes levied against Tenant’s equipment, furniture, fixtures and any other personal property located in or about the Premises. If any such taxes on Tenant’s equipment, furniture, fixtures and any other personal property are levied against Landlord or Landlord’s property or if the assessed value of Landlord’s property is increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or any other personal property and if Landlord pays the taxes based upon such increased assessment, which Landlord shall have the right to do regardless of the validity thereof but only under proper protest if requested by Tenant, Tenant shall upon demand repay to Landlord the taxes so levied against Landlord or the proportion of such taxes resulting from such increase in the assessment, as the case may be.

21

4.6. Landlord’s Books and Records. Upon Tenant’s written request given not more than six (6) months after Tenant’s receipt of a Statement for a particular Expense Year, and provided that Tenant is not then in default under this Lease beyond the applicable notice and cure period provided in this Lease, specifically including, but not limited to, a default beyond the applicable notice and cure period provided in this Lease with respect to the timely payment of Additional Rent (whether or not the same is the subject of the audit contemplated herein), Landlord shall furnish Tenant with such reasonable supporting documentation in connection with said Direct Expenses as Tenant may reasonably request. Landlord shall provide said documentation to Tenant within sixty (60) days after Tenant’s written request therefor. Within sixty (60) days after receipt of said documentation from Landlord (the “Audit Period”), if Tenant disputes the amount of Direct Expenses set forth in the Statement, an independent certified public accountant (which accountant (A) is a member of a nationally or regionally recognized certified public accounting firm which has previous experience in auditing financial operating records of landlords of office buildings, (B) is not working on a contingency fee basis [i.e., Tenant must be billed based on the actual time and materials that are incurred by the certified public accounting firm in the performance of the audit], and (C) shall not currently be providing or provide in the future accounting and/or lease administration services to another tenant in the Building and/or the Project in connection with a review or audit by such other tenant of the expense records being audited by Tenant), designated and paid for by Tenant, may, after reasonable notice to Landlord and at reasonable times, audit Landlord’s records with respect to the Statement at Landlord’s corporate offices, provided that (i) Tenant is not then in default under this Lease (beyond the applicable notice and cure periods provided under this Lease), (ii) Tenant has paid all amounts required to be paid under the applicable Estimate Statement and Statement, and (iii) a copy of the audit agreement between Tenant and its particular certified public accounting firm has been delivered to Landlord prior to the commencement of the audit. In connection with such audit, Tenant and Tenant’s certified public accounting firm must agree in advance to follow Landlord’s reasonable rules and procedures regarding an audit of the aforementioned Landlord records, and shall execute a commercially reasonable confidentiality agreement regarding such audit. Any audit report prepared by Tenant’s certified public accounting firm shall be delivered concurrently to Landlord and Tenant within the Audit Period. Tenant’s failure to audit the amount of Direct Expenses set forth in any Statement within the Audit Period shall be deemed to be Tenant’s approval of such Statement and Tenant, thereafter, waives the right or ability to audit the amounts set forth in such Statement. If after such audit, Tenant still disputes such Direct Expenses, an audit to determine the proper amount shall be made, at Tenant’s expense, by an independent certified public accountant (the “Accountant”) selected by Landlord and subject to Tenant’s reasonable approval; provided that if such audit by the Accountant proves that Direct Expenses set forth in the particular Statement were overstated by more than five percent (5%), then the cost of the Accountant, the cost of Tenant’s accounting, and the cost of such audit (and the actual and reasonable out-of-pocket cost of Tenant’s audit and auditor, not to exceed $10,000.00) shall be paid for by Landlord. Tenant hereby acknowledges that Tenant’s sole right to audit Landlord’s records and to contest the amount of Direct Expenses payable by Tenant shall be as set forth in this Section 4.6, and Tenant hereby waives any and all other rights pursuant to applicable law to audit such records and/or to contest the amount of Direct Expenses payable by Tenant.

22

5. USE OF PREMISES.

5.1. Permitted Use. Tenant shall use the Premises solely for the Permitted Use set forth in Section 7 of the Summary and Tenant shall not use or permit the Premises or the Project to be used for any other purpose or purposes whatsoever without the prior written consent of Landlord, which may be withheld in Landlord’s sole discretion.

5.2. Prohibited Uses. Tenant further covenants and agrees that Tenant shall not use, or suffer or permit any person or persons to use, the Premises or any part thereof for any use or purpose contrary to the provisions of the Rules and Regulations set forth in Exhibit D, attached hereto, or any Underlying Documents, and Tenant shall comply with, and Tenant’s rights and obligations under this Lease and Tenant’s use of the Premises shall be subject and subordinate to, all recorded easements, covenants, conditions, and restrictions now or hereafter affecting the Project; provided, however, that in no event shall any Underlying Documents interfere with or adversely affect, other than in a non-material manner, Tenant’s use of the Premises for the Permitted Use (or, subject to the terms of Section 1.1.3, above, access to or from the Premises or parking for the Premises or any of Tenant’s rights under this Lease). In addition, Tenant further covenants and agrees that Tenant shall not use, or suffer or permit any person or persons to use, the Premises or any part thereof for any use or purpose in violation of the laws of the United States of America, the State of California, the ordinances, regulations or requirements of the local municipal or county governing body or other lawful authorities having jurisdiction over the Project, including, without limitation, any such laws, ordinances, regulations or requirements relating to hazardous materials or substances, as those terms are defined by Applicable Laws now or hereafter in effect. Tenant shall not do or permit anything to be done in or about the Premises which will in any way materially obstruct or interfere with the rights of other tenants or occupants of the Project, or injure or annoy them or use or allow the Premises to be used for any unlawful purpose, nor shall Tenant cause, maintain or permit any nuisance in, on or about the Premises. .

5.3. Hazardous Materials.

5.3.1. Tenant’s Obligations.

5.3.1.1. Prohibitions. As a material inducement to Landlord to enter into this Lease with Tenant, Tenant has fully and accurately completed Landlord’s Pre-Leasing Environmental Exposure Questionnaire (the “Environmental Questionnaire”), which is attached as Exhibit F. Tenant agrees that except for those chemicals or materials, and their respective quantities, specifically listed on the Environmental Questionnaire, neither Tenant nor Tenant’s employees, contractors and subcontractors of any tier, entities with a contractual relationship with Tenant (other than Landlord), or any entity acting as an agent or sub-agent of Tenant (collectively, “Tenant’s Agents”) will produce, use, store or generate any “Hazardous Materials,” as that term is defined below, on, under or about the Premises, nor cause or permit any Hazardous Material to be brought upon, placed, stored, manufactured, generated, blended, handled, recycled, used or “Released,” as that term is defined below, on, in, under or about the Premises. If any information provided to Landlord by Tenant on the Environmental Questionnaire, or otherwise relating to information concerning Hazardous Materials is false, incomplete, or misleading in any material respect, the same shall be deemed a default by Tenant under this Lease. Tenant shall deliver to Landlord an updated Environmental Questionnaire at least once a year. Landlord’s prior written

23

consent shall be required to any Hazardous Materials use for the Premises not described on the initial Environmental Questionnaire, such consent to be withheld in Landlord’s sole discretion. Tenant shall not install or permit any underground storage tank on the Premises. For purposes of this Lease, “Hazardous Materials” means all flammable explosives, petroleum and petroleum products, waste oil, radon, radioactive materials, toxic pollutants, asbestos, polychlorinated biphenyls (“PCBs”), medical waste, chemicals known to cause cancer or reproductive toxicity, pollutants, contaminants, hazardous wastes, toxic substances or related materials, including without limitation any chemical, element, compound, mixture, solution, substance, object, waste or any combination thereof, which is or may be hazardous to human health, safety or to the environment due to its radioactivity, ignitability, corrosiveness, reactivity, explosiveness, toxicity, carcinogenicity, infectiousness or other harmful or potentially harmful properties or effects, or defined as, regulated as or included in, the definition of “hazardous substances,” “hazardous wastes,” “hazardous materials,” or “toxic substances” under any Environmental Laws. The term “Hazardous Materials” for purposes of this Lease shall also include any mold, fungus or spores, whether or not the same is defined, listed, or otherwise classified as a “hazardous material” under any Environmental Laws, if such mold, fungus or spores may pose a risk to human health or the environment or negatively impact the value of the Premises. For purposes of this Lease, “Release” or “Released” or “Releases” shall mean any release, deposit, discharge, emission, leaking, spilling, seeping, migrating, injecting, pumping, pouring, emptying, escaping, dumping, disposing, or other movement of Hazardous Materials into the environment.

5.3.1.2. Notices to Landlord. Tenant shall notify Landlord in writing as soon as possible but in no event later than five (5) days after (i) Tenant becomes aware of the occurrence of any actual, alleged or threatened Release of any Hazardous Material in, on, under, from, about or in the vicinity of the Premises (whether past or present), regardless of the source or quantity of any such Release, or (ii) Tenant becomes aware of any regulatory actions, inquiries, inspections, investigations, directives, or any cleanup, compliance, enforcement or abatement proceedings (including any threatened or contemplated investigations or proceedings) relating to or potentially affecting the Premises, or (iii) Tenant becomes aware of any claims by any person or entity relating to any Hazardous Materials in, on, under, from, about or in the vicinity of the Premises, whether relating to damage, contribution, cost recovery, compensation, loss or injury. Collectively, the matters set forth in clauses (i), (ii) and (iii) above are hereinafter referred to as “Hazardous Materials Claims”.

6.1.3. Electricity is separately metered (or sub-metered) at the Premises and shall be paid directly by Tenant to the applicable utility provider. If electricity is separately sub-metered (as opposed to separately metered), then Tenant shall pay to Landlord the cost of such utilities based on such sub-meter, including an administrative charge for Landlord’s supervision and reimbursement for any penalties for usage or other surcharges imposed by any utility company. Within twenty (20) days after receipt of Landlord’s statement of apportionment or statement setting forth the charges payable by Tenant, Tenant shall pay to Landlord, as Additional Rent, the cost of such electrical services so apportioned or so provided by Landlord. Notwithstanding anything to the contrary set forth herein, to the extent the Premises generates electricity demand on a shared resource (e.g. electricity for the central plant), the cost of such electricity shall be allocated to Tenant on a pro rata basis or other reasonable basis consistent with commercial reasonable property management practices.

6.1.4. Landlord shall not provide janitorial services for the Premises.

6.2. Overstandard Tenant Use. Tenant shall not, without Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, use heat-generating machines, machines other than normal fractional horsepower office machines, or equipment or lighting other than Building standard lights in the Premises, which may affect the

29

temperature otherwise maintained by the air conditioning system or increase the water normally furnished for the Premises by Landlord pursuant to the terms of Section 6.1 of this Lease. If Tenant uses water, heat or air conditioning in excess of that supplied by Landlord pursuant to Section 6.1 of this Lease, Tenant shall pay to Landlord, upon billing, Landlord’s actual cost of providing such excess consumption, without profit or overhead, but including the cost of the installation, operation, and maintenance of equipment which is installed in order to supply such excess consumption, and the cost of the increased wear and tear on existing equipment caused by such excess consumption; and Landlord may install devices to separately meter (or sub-meter) any increased use and in such event Tenant shall pay the increased cost directly to Landlord, on demand, at the rates charged by the public utility company furnishing the same, including the cost of such additional metering (or sub-metering) devices. Tenant’s use of electricity shall never exceed the capacity of the feeders to the Project or the risers or wiring installation If Tenant desires to use heat, ventilation or air conditioning during hours other than those for which Landlord is obligated to supply such utilities pursuant to the terms of Section 6.1 of this Lease, Tenant shall give Landlord such prior notice, if any, as Landlord shall from time to time establish as appropriate (provided that in no event shall Tenant be required to give more than two (2) hours’ prior written notice in connection therewith), of Tenant’s desired use in order to supply such utilities, and Landlord shall supply such utilities to Tenant at such hourly cost to Tenant (which shall be treated as Additional Rent) as Landlord shall from time to time calculate to reimburse Landlord for its actual cost of supplying such utilities, as set forth in this Section 6.2 above.

Tenant agrees that Landlord shall not be liable for damages, by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any service (including telephone and telecommunication services), or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by breakage, repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at the Building or Project after reasonable effort to do so, by any riot or other dangerous condition, emergency, accident or casualty whatsoever, by act or default of Tenant or other parties, or by any other cause; and such failures or delays or diminution shall never be deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent or performing any of its obligations under this Lease. Furthermore, Landlord shall not be liable under any circumstances for a loss of, or injury to, property or for injury to, or interference with, Tenant’s business, including, without limitation, loss of profits, however occurring, through or in connection with or incidental to a failure to furnish any of the services or utilities as set forth in this Article 6.

In addition, Tenant shall, at Tenant’s own expense, but subject to the terms and conditions of Article 8 below, and within any reasonable period of time specified by Landlord, promptly and adequately repair all damage to the Premises and replace or repair all damaged, broken, or worn fixtures and appurtenances, except for damage caused by ordinary wear and tear or beyond the reasonable control of Tenant; provided however, that, at Landlord’s option, or if Tenant fails to make such repairs, Landlord may, but need not, upon at least five (5) business days prior written notice to

30

Tenant, (except in the event of an emergency), make such repairs and replacements, and Tenant shall pay Landlord the cost thereof, including a percentage of the cost thereof (to be uniformly established for the Building and/or the Project) sufficient to reimburse Landlord for all overhead, general conditions, fees and other costs or expenses arising from Landlord’s involvement with such repairs and replacements forthwith upon being billed for same; provided further that, that if such repairs are due to the negligence or willful misconduct of Landlord, then Tenant shall nevertheless make such repairs at Landlord’s expense, or, if covered by Tenant’s insurance, then Landlord shall only be obligated to pay any deductible in connection therewith. Landlord agrees that at all times it will maintain the structural portions of the Building, including the foundation, floor/ceiling slabs, roof, curtain walls, exterior walls, exterior glass and mullions, columns, beams, shafts (including elevator shafts), stairs, stairwells, elevator cabs, mechanical, electrical and telephone closets and the Common Areas (collectively, the “Building Structure”) and the base Building mechanical, electrical, life safety, plumbing, sprinkler and HVAC systems installed or furnished by Landlord which serve the Premises (collectively, the “Building Systems”) in good order, condition and repair.

Subject to the terms of Section 19.5.2 and Article 27, below, Landlord may, but shall not be required to, enter the Premises at all reasonable times to make such repairs, alterations, improvements or additions to the Premises or to the Project or to any equipment located in the Project as Landlord shall desire or deem necessary or as Landlord may be required to do by governmental or quasi-governmental authority or court order or decree. 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 under any similar law, statute, or ordinance now or hereafter in effect.

8. ADDITIONS AND ALTERATIONS.

8.1. Landlord’s Consent to Alterations. Tenant may not make any improvements, alterations, additions or changes to the Premises or any mechanical, plumbing or HVAC facilities or systems pertaining to the Premises (collectively, the “Alterations”) without first procuring the prior written consent of Landlord to such Alterations, which consent shall be requested by Tenant not less than twenty-five (25) days prior to the commencement thereof, and which consent shall not be unreasonably withheld by Landlord, provided it shall be deemed reasonable for Landlord to withhold its consent to any Alteration which adversely affects the structural portions or the systems or equipment of the Building or is visible from the exterior of the Building. If Landlord fails to provide approve or disapprove of an Alteration within said twenty-five (25) day period, then Tenant may deliver a second request for approval at the expiration of said twenty-five (25) day period setting forth such failure containing the following sentence at the top of such notice in bold, capitalized font at least twelve (12) points in size: “LANDLORD’S FAILURE TO RESPOND TO THIS NOTICE WITHIN FIVE (5) BUSINESS DAYS SHALL RESULT IN LANDLORD’S DEEMED APPROVAL OF TENANT’S ALTERATION” (the “Reminder Notice”). Any such Reminder Notice shall include a complete copy of Tenant’s plans and specification for such Alteration. Landlord’s failure to provide approval or disapproval within five

31

(5) business days following Landlord’s receipt of a Reminder Notice shall conclusively be deemed approval of Tenant’s Alteration as presented. Notwithstanding the foregoing, Tenant shall be permitted to make Alterations following ten (10) business days’ notice to Landlord, but without Landlord’s prior consent, to the extent that such Alterations (i) do not adversely affect the building systems or equipment, (ii) are not visible from the exterior of the Building, and (iii) (A) are decorative only (,.(., installation of carpeting or painting of the Premises) or (B) cost less than $50,000.00 for a particular job of work. The construction of the initial improvements to the Premises shall be governed by the terms of the Tenant Work Letter and not the terms of this Article 8.

8.2. Manner of Construction. Landlord may impose, as a condition of its consent to any and all Alterations or repairs of the Premises or about the Premises, such requirements as Landlord in its reasonable discretion may deem desirable, including, but not limited to, the requirement that upon Landlord’s request, Tenant shall, at Tenant’s expense, remove such Alterations upon the expiration or any early termination of the Lease Term if such Alterations are Specialty Alterations (as that term is defined in Section 8.5 below). Tenant shall construct such Alterations and perform such repairs in a good and workmanlike manner, in conformance with any and all applicable federal, state, county or municipal laws, rules and regulations and pursuant to a valid building permit, issued by the city in which the Building is located (or other applicable governmental authority). Tenant shall not use (and upon notice from Landlord shall cease using) contractors, services, workmen, labor, materials or equipment that, in Landlord’s reasonable judgment, would disturb labor harmony with the workforce or trades engaged in performing other work, labor or services in or about the Building or the Common Areas. Upon completion of any Alterations (or repairs), Tenant shall deliver to Landlord final lien waivers from all contractors, subcontractors and materialmen who performed such work. In addition to Tenant’s obligations under Article 9 of this Lease, upon completion of any Alterations, Tenant agrees to cause a Notice of Completion to be recorded in the office of the Recorder of the County of San Diego in accordance with Section 8182 of the Civil Code of the State of California or any successor statute, and Tenant shall deliver to the Project construction manager a reproducible copy of the “as built” drawings of the Alterations as well as all permits, approvals and other documents issued by any governmental agency in connection with the Alterations.

8.3. Payment for Improvements. If Tenant orders any work directly from Landlord, Tenant shall pay to Landlord an amount equal to five percent (5%) of the cost of such work to compensate Landlord for all overhead, general conditions, fees and other costs and expenses arising from Landlord’s involvement with such work. If Tenant does not order any work directly from Landlord, Tenant shall reimburse Landlord for Landlord’s reasonable, actual, out-of-pocket costs and expenses actually incurred in connection with Landlord’s review of such work.

8.4. Construction Insurance. In addition to the requirements of Article 10 of this Lease, in the event that Tenant makes any Alterations, prior to the commencement of such Alterations, Tenant shall provide Landlord with evidence that Tenant carries “Builder’s All Risk” insurance in an amount reasonably approved by Landlord covering the construction of such Alterations, and such other insurance as Landlord may reasonably require, it being understood and agreed that all of such Alterations shall be insured by Tenant pursuant to Article 10 of this Lease immediately upon completion thereof. In addition, Tenant’s contractors and subcontractors shall be required to carry (i) Commercial General Liability Insurance in an amount reasonably approved

32

by Landlord, with Landlord, and, at Landlord’s option, Landlord’s property manager and project manager, as additional insureds in an amount reasonably approved by Landlord, and otherwise in accordance with the requirements of Article 10 of this Lease, and (ii) workers compensation insurance with a waiver of subrogation in favor of Landlord . Landlord may, if commercially reasonable under the circumstances, require Tenant to obtain a lien and completion bond or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien-free completion of such Alterations and naming Landlord as a co-obligee.

8.5. Landlord’s Property. All Alterations, improvements, fixtures, equipment and/or appurtenances which may be installed or placed in or about the Premises, from time to time, shall be at the sole cost of Tenant and shall be and become the property of Landlord and remain in place at the Premises following the expiration or earlier termination of this Lease, except that Tenant may remove any Alterations, improvements, fixtures and/or equipment which have not been paid for with any Tenant improvement allowance funds provided to Tenant by Landlord (including, without limitation, the Tenant Improvement Allowance (as that term is defined in Section 1.2 of the Work Letter), provided Tenant repairs any damage to the Premises and Building caused by such removal and returns the affected portion of the Premises to a building standard tenant improved condition. Notwithstanding the foregoing, Landlord may, by written notice to Tenant prior to the end of the Lease Term, or given following any earlier termination of this Lease, require Tenant, at Tenant’s expense, to remove any Alterations and/or improvements and/or systems and equipment within the Premises that are Specialty Alterations and to repair any damage to the Premises and Building caused by such removal and return the affected portion of the Premises to a building standard tenant improved condition as determined by Landlord; provided, however, that notwithstanding the foregoing, upon request by Tenant at the time of Tenant’s request for Landlord’s consent to any Alteration or improvement, Landlord shall notify Tenant whether any applicable Alteration or improvement that constitutes a Specialty Alteration will be required to be removed pursuant to the terms of this Section 8.5 (and, if following Tenant’s request Landlord fails to specify that any such Specialty Alteration will be subject to the removal requirement described herein, Landlord shall not have a subsequent right to designate such Specialty Alteration as subject to removal). If Tenant fails to complete such removal and/or to repair any damage caused by such removal and return the affected portion of the Premises to a building standard tenant improved condition as reasonably determined by Landlord, then Landlord may do so and may charge the cost thereof to Tenant. Tenant hereby protects, defends, indemnifies and holds Landlord harmless from any liability, cost, obligation, expense or claim of lien in any manner relating to the installation, placement, removal or financing of any such Alterations, improvements, fixtures and/or equipment in, on or about the Premises, which obligations of Tenant shall survive the expiration or earlier termination of this Lease. As used herein, “Specialty Alterations” shall mean any improvement that is not a normal and customary general office improvement, including, but not limited to, improvements which: (i) perforate, penetrate or require reinforcement of a floor slab (including, without limitation, interior stairwells or high-density filing or racking systems), (ii) consist of the installation of a raised flooring system, (iii) consist of the installation of a vault or other similar device or system intended to secure the Premises or a portion thereof in a manner that exceeds the level of security necessary for ordinary office space, (iv) involve material plumbing connections (such as, for example but not by way of limitation, kitchens (other than customary break-rooms with a refrigerator, sink and dishwasher), cafeteria, saunas, showers, and executive bathrooms outside of the Building core and/or special fire safety systems), (v) consist of the dedication of any material portion of the Premises to non-office usage (such as classrooms or

33

kitchens), or (vi) can be seen from outside the Premises. Landlord hereby acknowledges and agrees that the Tenant Improvements which (i) are a natural and logical extension of the improvement shown on the Space Plan (as that term is defined in of the Tenant Work Letter) and (ii) contain Building standard materials and finishes, shall not be deemed to be Specialty Alterations.

9. COVENANT AGAINST LIENS. Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of the work performed, materials furnished or obligations incurred by or on behalf of Tenant (which shall not include any work performed by Landlord whether on behalf of Landlord or otherwise), and shall protect, defend, indemnify and hold Landlord harmless from and against any claims, liabilities, judgments or costs (including, without limitation, reasonable attorneys’ fees and costs) arising out of same or in connection therewith. Tenant shall give Landlord notice at least twenty (20) days prior to the commencement of any such work on the Premises that is reasonably anticipated to costs in excess of $20,000.00 (or such additional time as may be necessary under applicable laws) to afford Landlord the opportunity of posting and recording appropriate notices of non-responsibility (to the extent applicable pursuant to then applicable laws). Tenant shall not cause or permit any lien of mechanics or materialmen or others to be placed against the Project, the Building or the Premises with respect to work or services claimed to have been performed for or materials claimed to have been furnished to Tenant, and, in case of any such lien attaching or notice of any lien, reserves the right to contest such lien, provided that Tenant shall, at its sole cost and expense, provide a bond in accordance with the California Civil Code Section 8424. If Tenant does not timely exercise its right to contest such lien, Tenant shall cause it to be immediately released and removed of record (by payment, statutory bond or other lawful means). If any such lien is not so released and removed (by payment, statutory bond or other lawful means) within ten (10) business days after notice of such lien is delivered by Landlord to Tenant, then Landlord may, at its option, take all action necessary to release and remove such lien, and all sums, costs and expenses, including reasonable attorneys’ fees and costs, incurred by Landlord in connection with such lien shall be deemed Additional Rent under this Lease and shall immediately be due and payable by Tenant. Nothing contained in this Lease shall authorize Tenant to do any act which shall subject Landlord’s title to the Building or Premises to any liens or encumbrances whether claimed by operation of law or express or implied contract. Any claim to a lien or encumbrance upon the Building or Premises arising in connection with any such work or respecting the Premises not performed by or at the request of Landlord shall be null and void, or at Landlord’s option shall attach only against Tenant’s interest in the Premises and shall in all respects be subordinate to Landlord’s title to the Project, Building and Premises

10. INSURANCE

10.1. Indemnification and Waiver. Except to the extent arising from the negligence or willful misconduct of Landlord or the Landlord Parties, Tenant hereby assumes all risk of damage to property or injury to persons in, upon or about the Premises from any cause whatsoever and agrees that Landlord, its partners, subpartners and their respective officers, agents, servants, employees, lenders, any property manager and independent contractors (collectively, “Landlord Parties”) shall not be liable for, and are hereby released from any responsibility for, any damage either to person or property or resulting from the loss of use thereof, which damage is sustained by Tenant or by other persons claiming through Tenant. Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any and all claims, loss, cost, damage, injury, expense and liability (including without limitation court costs and reasonable attorneys’ fees) incurred in

34

connection with or arising from any cause in, on or about the Premises, any acts, omissions or negligence of Tenant or of any person claiming by, through or under Tenant, or of the contractors, agents, servants, employees, invitees, guests or licensees of Tenant or any such person, in, on or about the Project or any breach of the terms of this Lease, either prior to, during, or after the expiration of the Lease Term, provided that the terms of the foregoing indemnity shall not apply to the gross negligence or willful misconduct of Landlord or any Landlord Parties. Should Landlord be named as a defendant in any suit brought against Tenant in connection with or arising out of Tenant’s occupancy of the Premises, Tenant shall pay to Landlord its costs and expenses incurred in such suit, including without limitation, its actual professional fees such as reasonable appraisers’, accountants’ and attorneys’ fees. Landlord shall indemnify, defend, protect, and hold harmless Tenant, its partners, and their respective officers, agents, servants, employees, and independent contractors (collectively, “Tenant Parties”) from any and all loss, cost, damage, expense and liability (including without limitation reasonable attorneys’ fees) arising from the gross negligence or willful misconduct of Landlord in, on or about the Project, except to the extent caused by the negligence or willful misconduct of the Tenant Parties. Notwithstanding anything to the contrary set forth in this Lease, either party’s agreement to indemnify the other party as set forth in this Section 10.1 shall be ineffective to the extent the matters for which such party agreed to indemnify the other party are covered by insurance required to be carried by the non-indemnifying party pursuant to this Lease. Further, Tenant’s agreement to indemnify Landlord and Landlord’s agreement to indemnify Tenant pursuant to this Section 10.1 are not intended to and shall not relieve any insurance carrier of its obligations under policies required to be carried pursuant to the provisions of this Lease, to the extent such policies cover, or if carried, would have covered the matters, subject to the parties’ respective indemnification obligations; nor shall they supersede any inconsistent agreement of the parties set forth in any other provision of this Lease. The provisions of this Section 10.1 shall survive the expiration or sooner termination of this Lease with respect to any claims or liability arising in connection with any event occurring prior to such expiration or termination.

10.2. Tenant’s Compliance With Landlord’s Property Insurance. Landlord shall insure the Building during the Lease Term against loss or damage under an “all risk” property insurance policy. 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 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. Tenant shall, at Tenant’s expense, comply with all insurance company requirements pertaining to the use of the Premises. If Tenant’s conduct or use of the Premises causes any increase in the premium for such insurance policies then Tenant shall reimburse Landlord for any such increase. Tenant, at Tenant’s expense, shall comply with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body. Tenant shall also provide Landlord and Landlord’s insurer(s) with such information regarding the use of the Premises and any damage to the Premises as they may require in connection with the placement of insurance for the Premises or the adjusting of any losses to the Premises.

35

10.3. Tenant’s Insurance. Tenant shall maintain the following coverages in the following amounts.

10.3.1. Commercial General Liability Insurance on an occurrence form (provided that product liability insurance may be on a claims-made form) covering the insured against claims of bodily injury, personal injury and property damage (including loss of use thereof) arising out of Tenant’s operations, and contractual liabilities including a contractual coverage, and including products and completed operations coverage, for limits of liability of not less than:

10.3.2. Property Insurance covering (i) all office furniture, business and trade fixtures, office equipment, free-standing cabinet work, movable partitions, merchandise and all other items of Tenant’s property on the Premises installed by, for, or at the expense of Tenant, (ii) the “Tenant Improvements,” as that term is defined in the Tenant Work Letter, and any other improvements which exist in the Premises as of the Lease Commencement Date (excluding the Base Building) (the “Original Improvements”), and (iii) all other improvements, alterations and additions to the Premises. Such insurance shall be written on an “all risks” of physical loss or damage basis, for the full replacement cost value (subject to reasonable deductible amounts) new without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance and shall include coverage for damage or other loss caused by fire or other peril including, but not limited to, vandalism and malicious mischief, theft, water damage of any type, including sprinkler leakage, bursting or stoppage of pipes, and explosion; provided that in no event shall such insurance be required to include coverage for damage or other loss caused by flood.

10.3.3. Business Income Interruption for one (1) year plus Extra Expense insurance in such amounts as will reimburse Tenant for actual direct or indirect loss of earnings attributable to the risks outlined in Section 10.3.2 above.

10.3.4. Worker’s Compensation and Employer’s Liability or other similar insurance pursuant to all applicable state and local statutes and regulations. The policy shall include a waiver of subrogation in favor of Landlord, its employees, Lenders and any property manager or partners.

10.4. Form of Policies. The minimum limits of policies of insurance required of Tenant under this Lease shall in no event limit the liability of Tenant under this Lease. Such insurance shall (i) name Landlord, its subsidiaries and affiliates, its property manager (if any) and any other party the Landlord so specifies, as an additional insured or loss payee, as applicable, including Landlord’s managing agent, if any; (ii) be issued by an insurance company having a rating of not less than A:IX in Best’s Insurance Guide or which is otherwise acceptable to Landlord and licensed to do business in the State of California; (iv) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and is non-contributing with any insurance required of Tenant; (v) be in form and content reasonably acceptable to Landlord; and

36

(vi) provide that said insurance shall not be canceled or coverage changed unless thirty (30) days’ prior written notice shall have been given to Landlord and any mortgagee of Landlord (unless such cancellation is the result of non-payment of premiums). Tenant shall deliver said policy or policies or certificates thereof to Landlord on or before the Lease Commencement Date and at least ten (10) days before the expiration dates thereof. In the event Tenant shall fail to procure such insurance, or to deliver such policies or certificate, Landlord may, at its option, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord within five (5) days after delivery to Tenant of bills therefor.

10.5. Subrogation. Landlord and Tenant hereby agree to look solely to, and seek recovery only from, their respective insurance carriers in the event of a property or business interruption loss to the extent that such coverage is agreed to be provided hereunder. The parties each hereby waive all rights and claims against each other for such losses, and waive all rights of subrogation of their respective insurers, provided such waiver of subrogation shall not affect the right to the insured to recover thereunder. The parties agree that their respective insurance policies do now, or shall, contain the waiver of subrogation.

10.6. Additional Insurance Obligations. Tenant shall carry and maintain during the entire Lease Term, at Tenant’s sole cost and expense, increased amounts of the insurance required to be carried by Tenant pursuant to this Article 10 and such other reasonable types of insurance coverage and in such reasonable amounts covering the Premises and Tenant’s operations therein, as may be reasonably requested by Landlord or Landlord’s lender, but in no event in excess of the amounts and types of insurance then being required by landlords of buildings comparable to and in the vicinity of the Building.

11. DAMAGE AND DESTRUCTION.

11.1. Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the Premises resulting from fire or any other casualty. If the Premises or any Common Areas serving or providing access to the Premises shall be damaged by fire or other casualty, Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of this Article 11, restore the Base Building and such Common Areas, and the Tenant Improvements, Original Improvements and Alterations made to the Premises by Tenant. Such restoration shall be to substantially the same condition of the Base Building and the Common Areas, the Tenant Improvements, Original Improvements and Alterations made to the Premises by Tenant prior to the casualty, except for modifications required by zoning and building codes and other laws or any other commercially reasonable modifications to the Common Areas deemed desirable by Landlord, which are consistent with the character of the Project, provided that access to the Premises shall not be unreasonably impaired and provided that the number of and general location of parking for Tenant’s benefit is not altered. Upon the occurrence of any damage to the Premises, upon notice (the “Landlord Repair Notice”) to Tenant from Landlord, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under Section 10.3 of this Lease, and Landlord shall repair any injury or damage to the Tenant Improvements and the Original Improvements installed in the Premises and shall return such Tenant Improvements and Original Improvements to their original condition; provided that if the cost of such repair by Landlord exceeds the amount of

37

insurance proceeds received by Landlord from Tenant’s insurance carrier (including by taking into account any deductible or self-insured retention), as assigned by Tenant, the cost of such repairs shall be paid by Tenant to Landlord prior to Landlord’s commencement of repair of the damage. Tenant shall in addition cooperate with requests for information regarding any repairs from Landlord’s insurer(s) by providing the requested information within ten (10) days after Tenant receives the request. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business resulting in any way from such damage 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, and any portion of the Premises are not occupied by Tenant as a result thereof, then during the time and to the extent the Premises are unfit for occupancy and not occupied by Tenant, the Rent shall be abated in proportion to the ratio that the amount of rentable square feet of the Premises which is unfit for occupancy for the purposes permitted under this Lease bears to the total rentable square feet of the Premises.

11.2. Landlord’s Option to Repair. Notwithstanding the terms of Section 11.1 of this Lease, Landlord may elect not to rebuild and/or restore the Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing of such termination within sixty (60) days after the date of discovery of the damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect only if the Building or Project shall be damaged by fire or other casualty or cause, whether or not the Premises are affected, and one or more of the following conditions is present: (i) in Landlord’s reasonable judgment, repairs cannot reasonably be completed within one hundred eighty (180) days after the date of discovery of the damage (when such repairs are made without the payment of overtime or other premiums); (ii) the holder of any mortgage on the Building or Project or ground lessor with respect to the Building or Project shall require that the insurance proceeds or any portion thereof be used to retire the mortgage debt, or shall terminate the ground lease, as the case may be; (iii) at least $500,000.00 of the cost to repair the damage is not covered by Landlord’s insurance policies (provided that any amounts payable as part of a deductible with respect to Landlord’s insurance policies shall be deemed to be not covered by Landlord’s insurance policies) (and would not have been covered had Landlord carried the policies that Landlord is required to carry pursuant to the terms of this Lease); or (iv) the damage occurs during the last twelve (12) months of the Lease Term; provided, however, that if Landlord does not elect to terminate this Lease pursuant to Landlord’s termination right as provided above, and the repairs cannot, in the reasonable opinion of Landlord, be completed within one hundred eighty (180) days after the date of discovery of the damage, then Tenant may elect, no earlier than sixty (60) days after the date of the damage and not later than ninety (90) days after the date of such damage, to terminate this Lease by written notice to Landlord effective as of the date specified in the notice, which date shall not be less than thirty (30) days nor more than sixty (60) days after the date such notice is given by Tenant. Furthermore, if neither Landlord nor Tenant has terminated this Lease, and the repairs are not actually completed within two hundred seventy (270) days after being commenced, Tenant shall have the right to terminate this Lease during the first five (5) business days of each calendar month following the end of such period until such time as the repairs are complete, by notice to Landlord (the “Damage Termination Notice”), effective as of a date set forth in the Damage Termination Notice (the “Damage Termination Date”), which Damage Termination Date shall not be less than five (5) business days following the end of each such month. Notwithstanding the foregoing, if Tenant delivers a Damage Termination Notice to Landlord, then Landlord shall have the right to suspend the occurrence of the Damage Termination Date for a period ending thirty (30) days after the Damage Termination Date set forth in the Damage Termination Notice by delivering to Tenant, within five (5) business days of Landlord’s receipt of the Damage Termination Notice, a certificate of Landlord’s contractor responsible for the repair of the damage certifying that it is such contractor’s good faith judgment that the repairs shall be substantially completed within thirty (30) days

38

after the Damage Termination Date. If repairs shall be substantially completed prior to the expiration of such thirty-day period, then the Damage Termination Notice shall be of no force or effect, but if the repairs shall not be substantially completed within such thirty-day period, then this Lease shall terminate upon the expiration of such thirty-day period. Notwithstanding the provisions of this Section 11.2, Tenant shall have the right to terminate this Lease under this Section 11.2 only if each of the following conditions is satisfied: (a) the damage to the Project by fire or other casualty was not caused by the gross negligence or intentional act of Tenant or its partners or subpartners and their respective officers, agents, servants, employees, and independent contractors; (b) Tenant is not then in default under this Lease beyond the applicable notice and cure period provided in this Lease; (c) as a result of the damage, Tenant cannot reasonably conduct business from the Premises; and, (d) as a result of the damage to the Project, Tenant does not occupy or use the Premises at all.

11.3. Waiver of Statutory Provisions. The provisions of this Lease, including this Article 11, 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, the Building or the Project, and any statute or regulation of the State of California, including, without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the Project.

12. NONWAIVER. No provision of this Lease shall be deemed waived by either party hereto unless expressly waived in a writing signed thereby. The waiver by either party hereto of any breach of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach of same or any other term, covenant or condition herein contained. 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 acceptance of a lesser amount than the Rent herein stipulated shall be deemed a waiver of Landlord’s right to receive the full amount due, nor shall any endorsement or statement on any check or payment or any letter accompanying such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the full amount due. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Lease Term or of Tenant’s right of possession hereunder, or after the giving of any notice shall reinstate, continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a suit, or after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment.

13. CONDEMNATION. If the whole or any part of the Premises, Building or Project shall be taken by power of eminent domain or condemned by any competent authority for any public or

39

quasi-public use or purpose, or if any adjacent property or street shall be so taken or condemned, or reconfigured or vacated by such authority in such manner as to require the use, reconstruction or remodeling of any part of the Premises, Building or Project, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease effective as of the date possession is required to be surrendered to the authority. Tenant shall not because of such taking assert any claim against Landlord or the authority for any compensation because of such taking and Landlord shall be entitled to the entire award or payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and fixtures belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the terms of this Lease, and for moving expenses, so long as such claims do not diminish the award available to Landlord, its ground lessor with respect to the Building or Project or its mortgagee, and such claim is payable separately to Tenant. All Rent shall be apportioned as of the date of such termination. If any part of the Premises shall be taken, and this Lease shall not be so terminated, the Rent shall be proportionately abated. Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of The California Code of Civil Procedure. Notwithstanding anything to the contrary contained in this Article 13, in the event of a temporary taking of all or any portion of the Premises for a period of one hundred and eighty (180) days or less, then this Lease shall not terminate but the Base Rent and the Additional Rent shall be abated for the period of such taking in proportion to the ratio that the amount of rentable square feet of the Premises taken bears to the total rentable square feet of the Premises. Landlord shall be entitled to receive the entire award made in connection with any such temporary taking.

14. ASSIGNMENT AND SUBLETTING.

14.1. Transfers. Tenant shall not, without the prior written consent of Landlord, assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof, or enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons other than Tenant and its employees and contractors (all of the foregoing are hereinafter sometimes referred to collectively as “Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “Transferee”). If Tenant desires Landlord’s consent to any Transfer, Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of the Transfer, which shall not be less than thirty (30) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the “Subject Space”), (iii) all of the terms of the proposed Transfer and the consideration therefor, including calculation of the “Transfer Premium”, as that term is defined in Section 14.3 below, in connection with such Transfer, the name and address of the proposed Transferee, and a copy of all existing executed and/or proposed documentation pertaining to the proposed Transfer, and (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, business credit and personal references and history of the proposed Transferee and any other information reasonably required by Landlord which will enable Landlord to determine the financial responsibility, character, and reputation of the proposed Transferee, nature of such Transferee’s business and proposed use of the Subject Space (provided that Landlord agrees to execute a commercially reasonable confidentiality

40

agreement cover the disclosure of such financial statements). Any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option, constitute a default by Tenant under this Lease. Whether or not Landlord consents to any proposed Transfer, Tenant shall pay Landlord’s reasonable review and processing fees, as well as any reasonable professional fees (including, without limitation, attorneys’, accountants’, architects’, engineers’ and consultants’ fees) incurred by Landlord, within thirty (30) days after written request by Landlord, not to exceed Two Thousand Five Hundred and No/100 Dollars ($2,500.00) for a Transfer in the ordinary course of business.

14.2. Landlord’s Consent. Landlord shall not unreasonably withhold, condition or delay its consent to any proposed Transfer of the Subject Space to the Transferee on the terms specified in the Transfer Notice, and shall grant or withhold its consent within ten (10) business days following Landlord’s receipt of a complete Transfer Notice. If Landlord fails to respond within such ten (10) business day period, then Tenant may send Landlord a reminder notice setting forth such failure containing the following sentence at the top of such notice in bold, capitalized font at least twelve (12) points in size: “LANDLORD’S FAILURE TO RESPOND TO THIS NOTICE WITHIN FIVE (5) BUSINESS DAYS SHALL RESULT IN LANDLORD’S DEEMED APPROVAL OF TENANT’S REQUEST FOR TRANSFER” (the “Transfer Reminder Notice”). Any such Transfer Reminder Notice shall include a complete copy of Tenant’s Transfer Notice. If Landlord fails to respond within five (5) business days after receipt of a Transfer Reminder Notice, then Tenant’s Transfer for which Tenant requested Landlord’s approval shall be deemed approved by Landlord. Without limitation as to other reasonable grounds for withholding consent, the parties hereby agree that it shall be reasonable under this Lease and under any applicable law for Landlord to withhold consent to any proposed Transfer where one or more of the following apply:

14.2.1. The Transferee is of a character or reputation or engaged in a business which is not consistent with the quality of the Building or the Project;

14.2.2. The Transferee is either a governmental agency or instrumentality thereof;

14.2.3. The Transferee is not a party of reasonable financial worth and/or financial stability in light of the responsibilities to be undertaken in connection with the Transfer on the date consent is requested, taking into account that Tenant shall remain fully liable under this Lease following such Transfer; or

14.2.4. The proposed Transfer would cause a violation of another lease for space in the Project, or would give an occupant of the Project a right to cancel its lease (provided that Landlord shall inform Tenant if a proposed Transfer would cause a violation of another lease for space in the Project, or would give an occupant of the Project a right to cancel its lease, within five (5) business days of Landlord’s receipt of both (i) a written request therefor from Tenant and (ii) information regarding such proposed Transfer which is adequate for Landlord to make such a determination).

If Landlord consents to any Transfer pursuant to the terms of this Section 14.2 (and does not exercise any recapture rights Landlord may have under Section 14.4 of this Lease), Tenant may within six (6) months after Landlord’s consent, but not later than the expiration of said six-month

41

period, enter into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to Section 14.1 of this Lease, provided that if there are any changes in the terms and conditions from those specified in the Transfer Notice such that Landlord would initially have been entitled to refuse its consent to such Transfer under this Section 14.2, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord’s right of recapture, if any, under Section 14.4 of this Lease). Notwithstanding anything to the contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord has unreasonably withheld, conditioned or delayed its consent under Section 14.2 or otherwise has breached or acted unreasonably under this Article 14, their sole remedies shall be a suit for contract damages (other than damages for injury to, or interference with, Tenant’s business including, without limitation, loss of profits, however occurring) or declaratory judgment and an injunction for the relief sought, and Tenant hereby waives 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.

14.3. Transfer Premium. If Landlord consents to a Transfer, as a condition thereto which the parties hereby agree is reasonable, Tenant shall pay to Landlord fifty percent (50%) of any “Transfer Premium,” as that term is defined in this Section 14.3, received by Tenant from such Transferee. “Transfer Premium” shall mean all rent, additional rent or other consideration payable by such Transferee in connection with the Transfer 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, and after deduction of (i) any costs of improvements made to the Subject Space in connection with such Transfer, (ii) brokerage commissions paid in connection with such Transfer, and (iii) reasonable legal and marketing fees or costs incurred in connection with such Transfer. “Transfer Premium” shall also include, but not be limited to, key money, bonus money or other cash consideration paid by Transferee to Tenant in connection 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. The determination of the amount of Landlord’s applicable share of the Transfer Premium shall be made on a monthly basis as rent or other consideration is received by Tenant under the Transfer.

14.4. Landlord’s Option as to Subject Space. Notwithstanding anything to the contrary contained in this Article 14, in the event Tenant contemplates a Transfer which, together with all prior Transfers then remaining in effect, would cause fifty percent (50%) or more of the Premises to be Transferred for more than fifty percent (50%) of the then remaining Lease Term (taking into account any extension of the Lease Term which has irrevocably exercised by Tenant), 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 delivered to Landlord pursuant to this Section 14.4 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

42

(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. 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 Premises, 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 14.4, then, subject to the other terms of this Article 14, for a period of nine (9) months (the “Nine Month Period”) commencing on the last day of such ten (10) Business Day period, Landlord shall not have any right to recapture the Contemplated Transfer Space with respect to any 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 Article 14. 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 14.4.

14.5. Effect of Transfer. If Landlord consents to a Transfer, (i) the terms and conditions of this Lease shall in no way be deemed to have been waived or modified, (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver to Landlord, promptly after execution, an original executed copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord, (iv) Tenant shall furnish upon Landlord’s request a complete statement, certified by an independent certified public accountant, or Tenant’s chief financial officer, setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from such Transfer, and (v) no Transfer relating to this Lease or agreement entered into with respect thereto, whether with or without Landlord’s consent, shall relieve Tenant or any guarantor of this Lease from any liability under this Lease, including, without limitation, in connection with the Subject Space. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any Transfer, and shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than three percent (3%), Tenant shall pay Landlord’s costs of such audit.

14.6. Additional Transfers. Except in connection with a transfer to a Permitted Transferee under Section 14.8, below, for purposes of this Lease, the term “Transfer” shall also include (i) if Tenant is a partnership, the withdrawal or change, voluntary, involuntary or by operation of law, of fifty percent (50%) or more of the partners, or transfer of fifty percent (50%) or more of partnership interests, within a twelve (12)-month period, or the dissolution of the partnership without immediate reconstitution thereof, and (ii) if Tenant is a closely held corporation (,.(., whose stock is not publicly held and not traded through an exchange or over the counter), (A) the dissolution, merger, consolidation or other reorganization of Tenant or (B) the sale or other transfer of an aggregate of fifty percent (50%) or more of the voting shares of Tenant (other than to immediate family members by reason of gift or death), within a twelve (12)-month period, or (C) the sale, mortgage, hypothecation or pledge of an aggregate of fifty percent (50%) or more of the value of the unencumbered assets of Tenant within a twelve (12)-month period.

43

14.7. Occurrence of Default. Any Transfer hereunder shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be terminated during the term of any Transfer, Landlord shall have the right to: (i) treat such Transfer as cancelled and repossess the Subject Space by any lawful means, or (ii) require that such Transferee attorn to and recognize Landlord as its landlord under any such Transfer. If Tenant shall be in default under this Lease (beyond any applicable notice and cure periods set forth in this Lease), Landlord is hereby irrevocably authorized, as Tenant’s agent and attorney-in-fact, to direct any Transferee to make all payments under or in connection with the Transfer directly to Landlord (which Landlord shall apply towards Tenant’s obligations under this Lease) until such default is cured. Such Transferee shall rely on any representation by Landlord that Tenant is in default hereunder, without any need for confirmation thereof by Tenant. Upon any assignment, the assignee shall assume in writing all obligations and covenants of Tenant thereafter to be performed or observed under this Lease. No collection or acceptance of rent by Landlord from any Transferee shall be deemed a waiver of any provision of this Article 14 or the approval of any Transferee or a release of Tenant from any obligation under this Lease, whether theretofore or thereafter accruing. In no event shall Landlord’s enforcement of any provision of this Lease against any Transferee be deemed a waiver of Landlord’s right to enforce any term of this Lease against Tenant or any other person. If Tenant’s obligations hereunder have been guaranteed, Landlord’s consent to any Transfer shall not be effective unless the guarantor also consents to such Transfer.

14.8. Deemed Consent Transfers. Notwithstanding anything to the contrary contained in this Lease, (A) an assignment or subletting of all or a portion of the Premises to an affiliate of Tenant (an entity which is controlled by, controls, or is under common control with, Tenant as of the date of this Lease), (B) a sale of corporate shares of capital stock in Tenant in connection with an initial public offering of Tenant’s stock on a nationally-recognized stock exchange, (C) a transfer of member interests or stock in Tenant in connection with any financing or any other member interest or stock transfer, (D) an assignment of this Lease to an entity which acquires all or substantially all of the stock or assets of Tenant, or (E) an assignment of this Lease to an entity which is the resulting entity of a merger or consolidation of Tenant during the Lease Term, shall not be deemed a Transfer requiring Landlord’s consent under this Article 14 and shall not be subject to the provisions of Sections 14.3 and 14.5 above (any such assignee or sublessee described in items (A) through (E) of this Section 14.8 hereinafter referred to as a “Permitted Transferee”), provided that (i) Tenant notifies Landlord promptly upon the effective date of any such assignment or sublease and promptly supplies Landlord with any documents or information reasonably requested by Landlord regarding such transfer or transferee as set forth above, (ii) Tenant is not in default, beyond any applicable notice and cure period, and such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease, (iii) such Permitted Transferee (or the Tenant entity immediately preceding the Permitted Transfer (the “Prior Tenant”), if such Prior Tenant remains the Tenant under this Lease) shall have a tangible net worth (not including goodwill as an asset) computed in accordance with generally accepted accounting principles (“Net Worth”) at least equal to the Net Worth of Tenant on the day immediately preceding the effective date of such assignment or sublease; provided that if the Prior Tenant is a surviving entity of such Permitted Transfer but is no longer the Tenant under this Lease, and such Prior Tenant remains liable under this Lease, then Tenant may combine the Net Worth of the Prior Tenant and the

44

Permitted Transferee to satisfy the foregoing Net Worth requirement; provided further that, in the event of a subletting of all or a portion of the Premises to an affiliate of Tenant pursuant to item (A) above, Tenant may combine the Net Worth of Tenant and such affiliate of Tenant to satisfy the foregoing Net Worth requirement, and (iv) no assignment relating to this Lease, whether with or without Landlord’s consent, shall relieve Tenant from any liability under this Lease, and, in the event of an assignment of Tenant’s entire interest in this Lease, the liability of Tenant and such transferee (other than a transferee pursuant to a stock or member interest transfer whereby this Lease is not actually assigned to a new entity) shall be joint and several. An assignee of Tenant’s entire interest in this Lease who qualifies as a Permitted Transferee may also be referred to herein as a “Permitted Transferee Assignee.” “Control,” as used in this Section 14.8, shall mean the ownership, directly or indirectly, of at least fifty-one percent (51%) of the voting securities of, or possession of the right to vote, in the ordinary direction of its affairs, of at least fifty-one percent (51%) of the voting interest in, any person or entity.

15. SURRENDER OF PREMISES; OWNERSHIP AND REMOVAL OF TRADE FIXTURES.

15.1. Surrender of Premises. No act or thing done by Landlord or any agent or employee of Landlord during the Lease Term shall be deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in writing by Landlord. The delivery of keys to the Premises to Landlord or any agent or employee of Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the return of such keys at any reasonable time upon request until this Lease shall have been properly terminated. The voluntary or other surrender of this Lease by Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not work a merger, and at the option of Landlord shall operate as an assignment to Landlord of all subleases or subtenancies affecting the Premises or terminate any or all such sublessees or subtenancies.

15.2. Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, subject to the provisions of this Article 15, quit and surrender possession of the Premises to Landlord in as good order and condition as when Tenant took possession and as thereafter improved by Landlord and/or Tenant, reasonable wear and tear, repairs which are specifically made the responsibility of Landlord hereunder, and/or damage due to casualty, excepted. Upon such expiration or termination, Tenant shall, without expense to Landlord, remove or cause to be removed from the Premises all debris and rubbish, and such items of furniture, equipment, free-standing cabinet work, movable partitions and other articles of personal property owned by Tenant or installed or placed by Tenant at its expense in the Premises, and such similar articles of any other persons claiming under Tenant, as Landlord may, in its sole discretion, require to be removed, and Tenant shall repair at its own expense all damage to the Premises and Building resulting from such removal; provided, however, in no event shall Tenant be obligated to (i) repair or replace any floor coverings or wall coverings, (ii) to repaint, or (iii) patch small holes in the walls and floors, provided in each case there has not been unreasonable wear and tear.

15.3. Environmental Assessment. In connection with its surrender of the Premises, Tenant shall submit to Landlord, at least one hundred twenty (120) days prior to the expiration

45

date of this Lease (or in the event of an earlier termination of this Lease, as soon as reasonably possible following such termination), an environmental Assessment of the Premises by a competent and experienced environmental engineer or engineering firm reasonably satisfactory to Landlord (pursuant to a contract approved by Landlord and providing that Landlord can rely on the Environmental Assessment), which (i) evidences that the Premises are in a clean and safe condition and free and clear of any Hazardous Materials; and (ii) includes a review of the Premises by an environmental consultant for asbestos, mold, fungus, spores, and other moisture conditions, on-site chemical use, and lead-based paint. If such Environmental Assessment reveals that remediation or Clean-up is required under any Environmental Laws, Tenant shall submit a remediation plan prepared by a recognized environmental consultant and shall be responsible for all costs of remediation and Clean-up, as more particularly provided in Section 5.3, above.

16. HOLDING OVER. If Tenant holds over after the expiration of the Lease Term or earlier termination thereof, with the express or implied consent of Landlord, such tenancy shall be from month-to-month only, and shall not constitute a renewal hereof or an extension for any further term. If Tenant holds over after the expiration of the Lease Term of earlier termination thereof, without the express or implied consent of Landlord, such tenancy shall be deemed to be a tenancy by sufferance only, and shall not constitute a renewal hereof or an extension for any further term. In either case, Base Rent shall be payable at a monthly rate equal to the product of (i) the Base Rent applicable during the last rental period of the Lease Term under this Lease or for the first month immediately following the earlier termination of the Lease Term, as applicable, and (ii) a percentage equal to 125% during the first (1^st) month immediately following the expiration or earlier termination of the Lease Term, 150% during the second (2^nd) and third (3^rd) months immediately following the expiration or earlier termination of the Lease Term, and 200% thereafter. Such month-to-month tenancy or tenancy by sufferance, as the case may be, shall be subject to every other applicable term, covenant and agreement contained herein. Nothing contained in this Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the Premises on or before the date that occurs thirty (30) days following the termination or expiration of this Lease, then, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys’ fees) and liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to surrender and any lost profits to Landlord resulting therefrom.

17. ESTOPPEL CERTIFICATES. Within ten (10) business days following a request in writing by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit E, attached hereto (or such other form as may be reasonably required by any prospective mortgagee or purchaser of the Project, or any portion thereof), indicating therein any exceptions thereto that may exist at that time, and shall also contain any other information reasonably requested by Landlord or Landlord’s mortgagee or prospective mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project. At any time during the Lease Term, Landlord may require Tenant to provide Landlord with a current financial

46

statement and financial statements of the two (2) years prior to the current financial statement year (provided that Landlord and any other recipient thereof shall execute a commercially reasonable non-disclosure agreement to protect the confidentiality of such statements). Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the normal practice of Tenant, shall be audited by an independent certified public accountant. Failure of Tenant to timely execute, acknowledge and deliver such estoppel certificate, if not cured within an additional three (3) business days after notice from Landlord pursuant to Section 19.1.4, below, shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements included in the estoppel certificate are true and correct, without exception.

18. SUBORDINATION. This Lease shall be subject and subordinate to all present and future ground or underlying leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances now or hereafter in force against the Building or Project or any part thereof, if any, and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust deeds, unless the holders of such mortgages, trust deeds or other encumbrances, or the lessors under such ground lease or underlying leases, require in writing that this Lease be superior thereto (collectively, the “Superior Holders”); provided, however, (a) Landlord represents that there are no Superior Holders as of the date of this Lease and (b) in connection with any future Superior Holders, Landlord shall deliver to Tenant a commercially reasonable subordination non-disturbance and attornment agreement executed by such Superior Holder (an “SNDA”) (which requires such Superior Holder to, among other things, accept this Lease, and not to disturb Tenant’s possession, so long as no default, beyond any applicable notice and cure period, is then in existence). Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of any such mortgage or deed in lieu thereof (or if any ground lease is terminated), to attorn, without any deductions or set-offs whatsoever, to the lienholder or purchaser or any successors thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor), if so requested to do so by such purchaser or lienholder or ground lessor, and to recognize such purchaser or lienholder or ground lessor as the lessor under this Lease, provided such lienholder or purchaser or ground lessor shall agree to accept this Lease and not disturb Tenant’s occupancy, so long as Tenant timely pays the rent and observes and performs the terms, covenants and conditions of this Lease to be observed and performed by Tenant (beyond any applicable notice and cure periods). Landlord’s interest herein may be assigned as security at any time to any lienholder. Tenant shall, within ten (10) days of request by Landlord, execute such further commercially reasonable instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination or superiority of this Lease to any such mortgages, trust deeds, ground leases or underlying leases. Tenant waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale.

19. DEFAULTS; REMEDIES.

19.1. Events of Default. The occurrence of any of the following shall constitute a default of this Lease by Tenant and Landlord shall not exercise any of the Landlord remedies set forth in Section 19.2, below (or any other remedy at law or equity except to the extent expressly set forth in this Lease), until one or more of the following has occurred:

47

19.1.1. Any failure by Tenant to pay any Rent or any other charge required to be paid under this Lease, or any part thereof, when due, which failure is not cured within five (5) business days after written notice from Landlord that said amount was not paid when due; or

19.1.2. Any failure by Tenant to observe or perform any other provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided that if the nature of such default is such that the same cannot reasonably be cured within a thirty (30) day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and cure such default; or

19.1.3. Abandonment of the Premises by Tenant pursuant to Section 1915.3 of the California Civil Code; or

19.1.4. The failure by Tenant to observe or perform according to the provisions of Articles 17 or 18 of this Lease, or Tenant’s use of the Premises in violation of Section 5.1 and/or Section 5.2 (specifically excluding the first (1^st) sentence of Section 5.2 of this Lease, as Section 19.1.2 above shall apply with respect to the failure by Tenant to observe or perform according to the provisions of the first (1^st) sentence of Section 5.2 of this Lease) of this Lease, or if Tenant completes a Transfer in violation of Article 14 of this Lease, in any of such cases where such failure continues for more than five (5) business days after notice from Landlord; or

The notice periods provided herein are in lieu of, and not in addition to, any notice periods provided by law.

19.2. Remedies Upon Default. Upon the occurrence of any event of default by Tenant, beyond any applicable notice and cure period expressly set forth in this Lease, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity (all of which remedies shall be distinct, separate and cumulative), the option to pursue any one or more of the following remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever.

19.2.1. Terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim or damages therefor; and Landlord may recover from Tenant the following:

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

(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 rental loss that Tenant proves could have been reasonably avoided; plus

48

(iii) The worth at the time of award of the amount by which the unpaid rent for the balance of the Lease Term after the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

(iv) Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, specifically including but not limited to, brokerage commissions and advertising expenses incurred, expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant; and

(v) At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable law.

The term “rent” as used in this Section 19.2 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 19.2.1(i) and (ii), above, the “worth at the time of award” shall be computed by allowing interest at the rate set forth in Article 25 of this Lease, but in no case greater than the maximum amount of such interest permitted by law. As used in Section 19.2.1(iii) above, the “worth at the time of award” 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 one percent (1%).

19.2.2. Landlord shall have the remedy described in California Civil Code Section 1951.4 (lessor may continue lease in effect after lessee’s breach and abandonment and recover rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations). Accordingly, if Landlord does not elect to terminate this Lease on account of any default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due.

19.2.3. Landlord shall at all times have the rights and remedies (which shall be cumulative with each other and cumulative and in addition to those rights and remedies available under Sections 19.2.1 and 19.2.2, above, or any law or other provision of this Lease), without prior demand or notice except as required by applicable law, to seek any declaratory, injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof.

19.3. Subleases of Tenant. Whether or not Landlord elects to terminate this Lease on account of any default by Tenant, as set forth in this Article 19, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. In the event of Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

49

19.4. Efforts to Relet. No re-entry or repossession, repairs, maintenance, changes, alterations and additions, reletting, appointment of a receiver to protect Landlord’s interests hereunder, or any other action or omission by Landlord shall be construed as an election by Landlord to terminate this Lease or Tenant’s right to possession, or to accept a surrender of the Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant’s obligations hereunder, unless express written notice of such intention is sent by Landlord to Tenant. Tenant hereby irrevocably waives any right otherwise available under any law to redeem or reinstate this Lease.

19.5. Landlord Default.

19.5.1. General. Notwithstanding anything to the contrary set forth in this Lease, Landlord shall not be in default in the performance of any obligation required to be performed by Landlord pursuant to this Lease unless Landlord fails to perform such obligation within thirty (30) days after the receipt of notice from Tenant specifying in detail Landlord’s failure to perform; provided, however, if the nature of Landlord’s obligation is such that more than thirty (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 thirty (30) day period and thereafter diligently pursue the same to completion. 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.

19.5.2. Abatement of Rent. Notwithstanding anything to the contrary in this Lease, in the event that Tenant is prevented from using, and does not use, the Premises or any portion thereof, as a result of (i) any repair, maintenance or alteration performed by Landlord, or which Landlord failed to perform, after the Lease Commencement Date and required by this Lease, which substantially interferes with Tenant’s use of the Premises, or (ii) any failure to provide services, utilities or access to the Premises as required to be provided by Landlord under this Lease, but excluding any utility or service that Tenant contracts directly with such utility or service provider, or, (iii) the negligence or intentional acts of Landlord or any Landlord Party (including without limitation any breach of this Lease by Landlord), or (iv) material interference with Tenant’s parking rights hereunder caused by any negligent or intentional acts of Landlord or any Landlord Party (provided that the terms of this item (iv) shall not be applicable to the extent Landlord provides Tenant with Reasonable Alternate Parking) (any such set of circumstances as set forth in items (i), (ii), (iii) or (iv), above, to be known as an “Abatement Event”), then Tenant shall give Landlord notice of such Abatement Event, and if such Abatement Event continues for five (5) consecutive business days after Landlord’s receipt of any such notice (the “Eligibility Period”), then the Base Rent, Tenant’s Share of Direct Expenses, and Tenant’s obligation to pay for parking (to the extent not utilized by Tenant) shall be abated or reduced, as the case may be, after expiration of the Eligibility Period for such time that Tenant continues to be so prevented from using, and does not use for the normal conduct of Tenant’s business, the Premises or a portion thereof, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented from using, and does not use, bears to the total rentable area of the Premises; provided, however, in the event that Tenant is prevented from using, and does not use, a portion of the Premises for a period of time in excess of the Eligibility Period and the remaining portion of the Premises is not sufficient to allow Tenant to effectively conduct its business therein, and if Tenant does not conduct its business from such remaining portion, then for such time after expiration of

50

the Eligibility Period during which Tenant is so prevented from effectively conducting its business therein, the Base Rent and Tenant’s Share of Direct Expenses for the entire Premises and Tenant’s obligation to pay for parking shall be abated for such time as Tenant continues to be so prevented from using, and does not use, the Premises. If, however, Tenant reoccupies any portion of the Premises during such period, the Rent allocable to such reoccupied portion, based on the proportion that the rentable area of such reoccupied portion of the Premises bears to the total rentable area of the Premises, shall be payable by Tenant from the date Tenant reoccupies such portion of the Premises. To the extent an Abatement Event is caused by an event covered by Articles 11 or 13 of this Lease, then Tenant’s right to ▇▇▇▇▇ rent shall be governed by the terms of such Article 11 or 13, as applicable, and the Eligibility Period shall not be applicable thereto. Such right to ▇▇▇▇▇ Base Rent and Tenant’s Share of Direct Expenses and parking charges (to the extent not utilized by Tenant) shall be Tenant’s sole and exclusive remedy for rent abatement at law or in equity for an Abatement Event. Except as provided in this Section 19.5.2, nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder. As used herein, “Reasonable Alternate Parking” shall mean reasonable alternative parking that is either (a) within a reasonable walking distance to the Premises, or (b) if Landlord provides a reasonable shuttle service, at Landlord’s sole cost and expense and not as an Operating Expense, between the alternate parking location and the Building, a shuttle service that does not require more than a ten (10) minute ride from the alternate parking location to the Building (or vice versa) (the “Shuttle Service”) and the Shuttle Service lasts no more than 30 days.

20.    COVENANT OF QUIET ENJOYMENT. Landlord covenants that Tenant, on paying the Rent, charges for services and other payments herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions and agreements hereof without interference by any persons lawfully claiming by or through Landlord. The foregoing covenant is in lieu of any other covenant express or implied.

21.    SECURITY DEPOSIT. Concurrently with Tenant’s execution of this Lease, Tenant shall deposit with Landlord a security deposit (the “Security Deposit”) in the amount set forth in Section 8 of the Summary, as security for the faithful performance by Tenant of all of its obligations under this Lease. If Tenant defaults (beyond any applicable notice and cure period expressly set forth in this Lease) with respect to any provisions of this Lease, including, but not limited to, the provisions relating to the payment of Rent, the removal of property and the repair of resultant damage, Landlord may, without notice to Tenant, but shall not be required to apply all or any part of the Security Deposit for the payment of any Rent or any other sum in default and Tenant shall, upon demand therefor, restore the Security Deposit to its original amount. Any unapplied portion of the Security Deposit shall be returned to Tenant, or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder, within thirty (30) days following the expiration of the Lease Term. Tenant shall not be entitled to any interest on the Security Deposit. Tenant hereby irrevocably waives and relinquishes any and all rights, benefits, or protections, if any, Tenant now has, or in the future may have, under Section 1950.7 of the California Civil Code, any successor statute, and all other provisions of law, now or hereafter in effect, including, but not limited to, any provision of law which (i) establishes the time frame by which a landlord must refund a security deposit under a lease, and/or (ii) provides that a landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage

51

caused by a tenant or to clean the subject premises. Tenant acknowledges and agrees that (a) any statutory time frames for the return of a security deposit are superseded by the express period identified in this Article 21, above, and (b) rather than be so limited, Landlord may claim from the Security Deposit (1) any and all sums expressly identified in this Article 21, above, and (2) any additional sums reasonably necessary to compensate Landlord for any and all losses or damages caused by Tenant’s default of this Lease, including, but not limited to, all damages or rent due upon termination of Lease pursuant to Section 1951.2 of the California Civil Code.

22.    COMMUNICATIONS AND COMPUTER LINE. Tenant may install, maintain, replace, remove or use any communications or computer wires and cables serving the Premises (collectively, the “Lines”), provided that Tenant shall obtain Landlord’s prior written consent (which shall not be unreasonably withheld, conditioned or delayed), use an experienced and qualified contractor reasonably approved in writing by Landlord, and comply with all of the other provisions of Articles 7 and 8 of this Lease. Tenant shall pay all costs in connection therewith. Landlord reserves the right, upon notice to Tenant prior to the expiration or earlier termination of this Lease, to require that Tenant, at Tenant’s sole cost and expense, remove any Lines located in or serving the Premises prior to the expiration or earlier termination of this Lease.

23.    SIGNS.

23.1.    Exterior Signage. Subject to Applicable Laws, the terms and conditions of this Article 23 below and Landlord’s prior written approval, which shall not be unreasonably withheld, conditioned or delayed, and provided all signs are compatible with the Project’s sign criteria and are in keeping with the quality, design and style of the Building and Project, Tenant, at its sole cost and expense, may install (i) identification signage on one (1) slot on each of those certain two (2) existing monument signs (the “Monuments”) located adjacent to the Building, as set forth on Exhibit G attached hereto, (ii) one (1) identification sign located on the exterior of the Building in one (1) location to be mutually and reasonably determined by Landlord and Tenant (the “Building Exterior Signage”) and (iii) Building standard tenant directory signage at the entrance to the Building (collectively, “Tenant’s Signage”); provided, however, in no event shall Tenant’s Signage include an “Objectionable Name,” as that term is defined in Section 23.2, of this Lease. Notwithstanding the foregoing, in no event shall the Building Exterior Signage, at any time, prevent the other then tenant(s) of the Building (specifically excluding Tenant) from maintaining (i) at least one (1) identification sign, in the aggregate, located on the exterior of the Building, or (ii) exterior signage on at least fifty percent (50%) of the Permitted Signage Area (as that term is defined below) of the Building, in the aggregate. All such signage shall be subject to Tenant’s obtaining all required governmental approvals and shall conform to all Applicable Laws, including, without limitation, zoning laws) and then-existing Underlying Documents. The location of Tenant’s identification signage slot on each of the two (2) Monuments is set forth on Exhibit G attached hereto. All permitted signs shall be maintained by Tenant at its expense in a first-class and safe condition and appearance. All costs associated with Tenant’s Signage, including, without limitation, the costs to purchase, install and maintain Tenant’s Signage, shall be borne exclusively by Tenant. Upon the expiration or earlier termination of this Lease, Tenant shall remove all of its signs at Tenant’s sole cost and expense. The graphics, materials, color, design, lettering, lighting, size, illumination, specifications and exact location of Tenant’s Signage (collectively, the “Sign Specifications”) shall be subject to the prior written approval of Landlord, which approval shall not be unreasonably withheld, conditioned or delayed, and shall be consistent and compatible with

52

the quality and nature of the Project. Tenant hereby acknowledges that, notwithstanding Landlord’s approval of Tenant’s Signage, Landlord has made no representation or warranty to Tenant with respect to the probability of obtaining all necessary governmental approvals and permits for Tenant’s Signage. In the event Tenant does not receive the necessary governmental approvals and permits for Tenant’s Signage, Tenant’s and Landlord’s rights and obligations under the remaining terms, covenants and conditions of this Lease shall be unaffected. For purposes hereof, “Permitted Signage Area” shall mean the square footage of the surface area of the exterior of the Building that would be available and permitted for exterior tenant signage in accordance with Applicable Laws (including, without limitation, zoning laws) based on the assumption that the Building Exterior Signage is not installed on the Building.

23.2.    Objectionable Name. Tenant’s Signage shall not include a name or logo which relates to an entity which is of a character or reputation, or is associated with a political faction or orientation, which is inconsistent with the quality of the Project, or which would otherwise reasonably offend a landlord of the Comparable Buildings (an “Objectionable Name”). The parties hereby agree that the following name, or any reasonable derivation thereof, shall be deemed not to constitute an Objectionable Name: “BioAtla, LLC”

23.3.    Prohibited Signage and Other Items. Any signs, notices, logos, pictures, names or advertisements which are installed and that have not been separately approved by Landlord may be removed without notice by Landlord at the sole expense of Tenant. Any window coverings, or blinds shall be subject to the prior approval of Landlord, which shall not be unreasonably withheld, conditioned or delayed. Any signs or other items visible from the exterior of the Premises or Building (other than Tenant’s Signage or window coverings or blinds), shall be subject to the prior approval of Landlord, in its sole discretion.

23.4.    Termination of Right to Tenant’s Signage. The rights contained in this Article 23 shall be personal to Original Tenant and its Permitted Transferee Assignee, and may only be exercised and maintained by such parties (and not any other assignee, sublessee or other transferee of the Original Tenant’s interest in this Lease) to the extent (:) they are not in default under this Lease (beyond any applicable notice and cure period) and (y) with respect to the monument signage and the Building Exterior Signage, if they occupy the entire Premises.

24.    COMPLIANCE WITH LAW. Tenant shall not do anything or suffer anything to be done in or about the Premises or the Project which will in any way conflict with any law, statute, ordinance or other governmental rule, regulation or requirement now in force or which may hereafter be enacted or promulgated (collectively, “Applicable Laws”). Except as otherwise specifically set forth in Section 1.2 of the Tenant Work Letter, at its sole cost and expense, Tenant shall promptly comply with any Applicable Laws which relate to the Building (including, without limitation, the Base Building), but not with respect to any Common Areas located outside the Building unless and to the extent such obligations are triggered by Alterations made by Tenant to the Premises to the extent such Alterations are not normal and customary business office improvements, or triggered by the Tenant Improvements to the extent such Tenant Improvements are not expressly depicted on the Space Plan or are not normal and customary business office improvements, or triggered by Tenant’s use of the Premises for non-general office use (“Tenant’s Compliance With Law Obligations”). Except as otherwise specifically set forth in Section 1.2 of the Tenant Work Letter, Should any standard or regulation now or hereafter be imposed on

53

Landlord or Tenant by a state, federal or local governmental body charged with the establishment, regulation and enforcement of occupational, health or safety standards for employers, employees, landlords or tenants, then Tenant agrees, at its sole cost and expense, to comply promptly with such standards or regulations. Tenant shall be responsible, at its sole cost and expense, to make all alterations to the Premises as are required to comply with Tenant’s Compliance With Law Obligations. Landlord shall comply with all Applicable Laws relating to the Base Building, provided that compliance with such Applicable 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 for the Premises, or would unreasonably affect the safety of Tenant’s employees. The judgment of any court of competent jurisdiction or the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any of said governmental measures, shall be conclusive of that fact as between Landlord and Tenant. For purposes of Section 1938 of the California Civil Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that the Project, Building and Premises have not undergone inspection by a Certified Access Specialist (CASp). As required by Section 1938(e) of the California Civil Code, Landlord hereby states as follows: “A Certified Access Specialist (CASp) can inspect the subject premises and determine whether the subject premises comply with all of the applicable construction-related accessibility standards under state law. Although state law does not require a CASp inspection of the subject premises, the commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for the CASp inspection, and the cost of making any repairs necessary to correct violations of construction-related accessibility standards within the premises.” In furtherance of the foregoing, Landlord and Tenant hereby agree as follows: (a) any CASp inspection requested by Tenant shall be conducted, at Tenant’s sole cost and expense, by a CASp approved in advance by Landlord, while any CASp inspection initiated by Landlord shall be conducted, at Landlord’s sole cost and expense, by a CASp designated by Landlord; and (b) with respect to improvements or repairs required to correct violations discovered during a CASp inspection initiated by Tenant, pursuant to this Article 24 above, Tenant, at its cost, is responsible for making any repairs within the Premises to correct violations of construction-related accessibility standards (except as expressly set forth in the Tenant Work Letter); and, if anything done by or for Tenant in its use or occupancy of the Premises shall require repairs to the Building (outside the Premises) to correct violations of construction-related accessibility standards, then Tenant shall, at Landlord’s option, either perform such repairs at Tenant’s sole cost and expense or reimburse Landlord upon demand, as Additional Rent, for the cost to Landlord of performing such repairs, provided that Landlord shall be solely responsible for the costs of performing such improvements or repairs to correct such violations of construction-related accessibility standards if such violations were discovered during a CASp inspection initiated by Landlord.

25.    LATE CHARGES. If any installment of Rent or any other sum due from Tenant shall not be received by Landlord or Landlord’s designee within five (5) business days after Tenant’s receipt of written notice from Landlord that said amount is due, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount plus any reasonable attorneys’ fees incurred by Landlord by reason of Tenant’s failure to pay Rent and/or other charges when due hereunder. The late charge shall be deemed Additional Rent and the right to require it shall be in

54

addition to all of Landlord’s other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting Landlord’s remedies in any manner. In addition to the late charge described above, any Rent or other amounts owing hereunder which are not paid within ten (10) days after the date they are due shall bear interest from the date when due until paid at a rate per annum equal to the lesser of (i) the annual “Bank Prime Loan” rate cited in the Federal Reserve Statistical Release Publication G.13(415), published on the first Tuesday of each calendar month (or such other comparable index as Landlord and Tenant shall reasonably agree upon if such rate ceases to be published) plus four (4) percentage points, and (ii) the highest rate permitted by applicable law.

26.    LANDLORD’S RIGHT TO CURE DEFAULT; PAYMENTS BY TENANT.

26.1.    Landlord’s Cure. All covenants and agreements to be kept or performed by Tenant under this Lease shall be performed by Tenant at Tenant’s sole cost and expense and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant shall fail to perform any obligation under this Lease, and such failure shall continue in excess of the time allowed under Section 19.1.2, above, Landlord may, but shall not be obligated to, after providing Tenant with at least five (5) business days’ notice that Landlord intends to so cure (except in the event of an emergency, where no prior notice shall be required, except that Landlord shall nonetheless use commercially reasonable efforts to notify Tenant), make any such payment or perform any such act on Tenant’s part without waiving its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder.

26.2.    Tenant’s Reimbursement. Except as may be specifically provided to the contrary in this Lease, Tenant shall pay to Landlord, upon delivery by Landlord to Tenant of statements therefor, sums equal to expenditures reasonably made and obligations incurred by Landlord in connection with the remedying by Landlord of Tenant’s defaults pursuant to the provisions of Section 26.1. Tenant’s obligations under this Section 26.2 shall survive the expiration or sooner termination of the Lease Term.

27.    ENTRY BY LANDLORD. Landlord reserves the right at all reasonable times and upon not less than one (1) business days’ notice to Tenant (except in the case of an emergency) to enter the Premises to (i) inspect them; (ii) show the Premises to prospective purchasers, or to current or prospective mortgagees, ground or underlying lessors or insurers or, during the last twelve (12) months of the Lease Term, to prospective tenants; (iii) post notices of nonresponsibility (to the extent applicable pursuant to then applicable law); (iv) to the extent permitted or required by express provisions of this Lease, to alter, improve or repair the Premises or the Building, or for structural alterations, repairs or improvements to the Building or the Building’s systems and equipment, or (v) exercise its rights under Article 26 of this Lease, above. Landlord may make any such entries without the abatement of Rent, except as otherwise provided in this Lease, and may take such reasonable steps as required to accomplish the stated purposes. Except in the event of an emergency, Landlord shall employ commercially reasonable efforts to minimize interference with the conduct of Tenant’s business in connection with entries into the Premises. In an emergency, Landlord shall have the right to use any means that Landlord may deem proper to open the doors in and to the Premises. Provided that Landlord employs commercially reasonable efforts to minimize interference with the conduct of Tenant’s business in connection with entries into the

55

Premises, Tenant hereby waives any claims for any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby. Any entry into the Premises by Landlord in the manner hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the Premises. No provision of this Lease shall be construed as obligating Landlord to perform any repairs, alterations or decorations except as otherwise expressly agreed to be performed by Landlord herein.

28.    TENANT PARKING. Tenant shall have the right, but not the obligation, to use, the amount of unreserved parking spaces set forth in Section 9 of the Summary, in the on-site parking facility (or facilities) which serve the Project. Tenant shall abide by all reasonable non-discriminatory rules and regulations which are prescribed from time to time for the orderly operation and use of the Project parking facility where the parking spaces are located (including any sticker or other identification system established by Landlord and the prohibition of vehicle repair and maintenance activities in the Project parking facilities), and shall cooperate in seeing that Tenant’s employees and visitors also comply with such rules and regulations. Tenant’s use of the Project parking facility shall be at Tenant’s sole risk and Tenant acknowledges and agrees that Landlord shall have no liability whatsoever for damage to the vehicles of Tenant, its employees and/or visitors, or for other personal injury or property damage or theft relating to or connected with the parking rights granted herein or any of Tenant’s, its employees’ and/or visitors’ use of the parking facilities, provided that the foregoing shall not limit Landlord’s liability, if any, pursuant to applicable law for personal injury and property damage to the extent caused by the gross negligence or willful misconduct of Landlord, its agents, employees or contractors. Tenant shall pay to Landlord for its use of the unreserved parking spaces on a monthly basis at the prevailing rate charged from time to time for parking within the Project parking facility; provided that during the initial Lease Term, such unreserved parking spaces shall be provided at no additional charge to Tenant (other than Operating Expenses to the extent allowed by the terms of Section 4.2.4 of this Lease); provided further that Tenant shall also be responsible for the full amount of any taxes imposed by any governmental authority in connection with the renting of such unreserved parking spaces by Tenant or the use of the Project parking facility by Tenant.

29.    MISCELLANEOUS PROVISIONS.

29.1.    Terms; Captions. The words “Landlord” and “Tenant” as used herein shall include the plural as well as the singular.

29.2.    Binding Effect. Subject to all other provisions of this Lease, each of the covenants, conditions and provisions of this Lease shall extend to and shall, as the case may require, bind or inure to the benefit not only of Landlord and of Tenant, but also of their respective heirs, personal representatives, successors or assigns, provided this clause shall not permit any assignment by Tenant contrary to the provisions of Article 14 of this Lease.

29.3.    No Air Rights. No rights to any view or to light or air over any property, whether belonging to Landlord or any other person, are granted to Tenant by this Lease. If at any time any

29.4.    Modification of Lease. Should any current or prospective mortgagee or ground lessor for the Building or Project require a modification of this Lease, which modification will not cause an increased cost or expense to Tenant or in any other way adversely change the rights and obligations of Tenant hereunder, then and in such event, Tenant agrees that this Lease may be so modified and agrees to execute whatever documents are reasonably required therefor and to deliver the same to Landlord within ten (10) business days following a request therefor. At the request of Landlord or any mortgagee or ground lessor, Tenant agrees to execute a short form of Lease and deliver the same to Landlord within ten (10) business days following the request therefor.

29.5.    Transfer of Landlord’s Interest. Tenant acknowledges that Landlord has the right to transfer all or any portion of its interest in the Project or Building and in this Lease, and Tenant agrees that in the event of any such transfer, Landlord shall automatically be released from all liability under this Lease arising after the date of transfer and Tenant agrees to look solely to such transferee for the performance of Landlord’s obligations hereunder after the date of transfer and such transferee shall be deemed to have fully assumed and be liable for all obligations of this Lease to be performed by Landlord, including the return of any Security Deposit, and Tenant shall attorn to such transferee.

29.6.    Prohibition Against Recording. Except as provided in Section 29.4 of this Lease, neither this Lease, nor any memorandum, affidavit or other writing with respect thereto, shall be recorded by Tenant or by anyone acting through, under or on behalf of Tenant.

29.7.    Landlord’s Title. Landlord’s title is and always shall be paramount to the title of Tenant. Nothing herein contained shall empower Tenant to do any act which can, shall or may encumber the title of Landlord.

29.8.    Relationship of Parties. Nothing contained in this Lease shall be deemed or construed by the parties hereto or by any third party to create the relationship of principal and agent, partnership, joint venturer or any association between Landlord and Tenant.

29.9.    Application of Payments. Landlord shall have the right to apply payments received from Tenant pursuant to this Lease, regardless of Tenant’s designation of such payments, to satisfy any obligations of Tenant hereunder, in such order and amounts as Landlord, in its sole discretion, may elect.

29.10.    Time of Essence. Time is of the essence with respect to the performance of every provision of this Lease in which time of performance is a factor.

29.11.    Partial Invalidity. If any term, provision or condition contained in this Lease shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term, provision or condition to persons or circumstances other than those with respect to which it is invalid or unenforceable, shall not be affected thereby, and each and every other term, provision and condition of this Lease shall be valid and enforceable to the fullest extent possible permitted by law.

57

29.12.    No Warranty. In executing and delivering this Lease, Tenant has not relied on any representations, including, but not limited to, any representation as to the amount of any item comprising Additional Rent or the amount of the Additional Rent in the aggregate or that Landlord is furnishing the same services to other tenants, at all, on the same level or on the same basis, or any warranty or any statement of Landlord which is not set forth herein or in one or more of the exhibits attached hereto.

29.13.    Landlord Exculpation. The liability of Landlord or the Landlord Parties to Tenant for any default by Landlord under this Lease or arising in connection herewith or with Landlord’s operation, management, leasing, repair, renovation, alteration or any other matter relating to the Project or the Premises shall be limited solely and exclusively to an amount which is equal to the lesser of (a) the interest of Landlord in the Building or (b) the equity interest Landlord would have in the Building if the Building were encumbered by third-party debt in an amount equal to sixty percent (60%) of the value of the Building (as such value is reasonably determined by Landlord), in either case including any sales or insurance proceeds received by Landlord or the Landlord Parties in connection with the Project, Building or Premises. Neither Landlord, nor any of the Landlord Parties shall have any personal liability therefor, and Tenant hereby expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or under Tenant. The limitations of liability contained in this Section 29.13 shall inure to the benefit of Landlord’s and the Landlord Parties’ present and future partners, beneficiaries, officers, directors, trustees, shareholders, agents and employees, and their respective partners, heirs, successors and assigns. Under no circumstances shall any present or future partner of Landlord (if Landlord is a partnership), or trustee or beneficiary (if Landlord or any partner of Landlord is a trust), have any liability for the performance of Landlord’s obligations under this Lease. Notwithstanding any contrary provision herein, 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, indirect, special or punitive damages (including but not limited to, damages with respect to loss of profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill or loss of use, in each case, however occurring, or loss to inventory, scientific research, scientific experiments, laboratory animals, products, specimens, samples, and/or scientific, business, accounting and other records of every kind and description kept at the premises and any and all income derived or derivable therefrom, 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 as set forth in Article 16, above.

29.14.    Entire Agreement. It is understood and acknowledged that there are no oral agreements between the parties hereto affecting this Lease and this Lease constitutes the parties’ entire agreement with respect to the leasing of the Premises and supersedes and cancels any and all previous negotiations, arrangements, brochures, agreements and understandings, if any, between the parties hereto or displayed by Landlord to Tenant with respect to the subject matter thereof, and none thereof shall be used to interpret or construe this Lease. None of the terms, covenants, conditions or provisions of this Lease can be modified, deleted or added to except in writing signed by the parties hereto.

58

29.15.    Right to Lease. Landlord reserves the absolute right to effect such other tenancies in the Project as Landlord in the exercise of its sole business judgment shall determine to best promote the interests of the Building or Project. Tenant does not rely on the fact, nor does Landlord represent, that any specific tenant or type or number of tenants shall, during the Lease Term, occupy any space in the Building or Project.

29.16.    Force Majeure. Any prevention, delay or stoppage due to strikes, lockouts, labor disputes, acts of God, acts of war, terrorist acts, inability to obtain services, labor, or materials or reasonable substitutes therefor, governmental actions, civil commotions, fire or other casualty, and other causes beyond the reasonable control of the party obligated to perform, except with respect to the obligations imposed with regard to Rent and other monetary amounts to be paid by either party to the other pursuant to this Lease (collectively, a “Force Majeure”), notwithstanding anything to the contrary contained in this Lease, shall excuse the performance of such party for a period equal to any such prevention, delay or stoppage and, therefore, if this Lease specifies a time period for performance of an obligation of either party, that time period shall be extended by the period of any delay in such party’s performance caused by a Force Majeure.

29.17.    Waiver of Redemption by Tenant. Tenant hereby waives, for Tenant and for all those claiming under Tenant, any and all rights now or hereafter existing to redeem by order or judgment of any court or by any legal process or writ, Tenant’s right of occupancy of the Premises after any termination of this Lease.

29.18.    Notices. All notices, demands, statements, designations, approvals or other communications (collectively, “Notices”) given or required to be given by either party to the other hereunder or by law shall be in writing, shall be (A) sent by United States certified or registered mail, postage prepaid, return receipt requested (“Mail”), (B) delivered by a nationally recognized overnight courier that provides proof of delivery, or (C) delivered personally. Any Notice shall be sent, transmitted, or delivered, as the case may be, to Tenant at the appropriate address set forth in Section 10 of the Summary, or to such other place as Tenant may from time to time designate in a Notice to Landlord, or to Landlord at the addresses set forth below, or to such other places as Landlord may from time to time designate in a Notice to Tenant. Any Notice will be deemed given upon actual (or attempted but refused) delivery. As of the date of this Lease, any Notices to Landlord must be sent, transmitted, or delivered, as the case may be, to the following addresses:

29.19.    Joint and Several. If there is more than one tenant, the obligations imposed upon Tenant under this Lease shall be joint and several.

29.20.    Authority. If Tenant is a corporation, trust or partnership, each individual executing this Lease on behalf of Tenant hereby represents and warrants that Tenant is a duly formed and existing entity qualified to do business in the State of California and that Tenant has full right and authority to execute and deliver this Lease and that each person signing on behalf of Tenant is authorized to do so. In such event, Tenant shall, within ten (10) days after execution of this Lease, deliver to Landlord satisfactory evidence of such authority and, if a corporation, upon demand by Landlord, also deliver to Landlord satisfactory evidence of (i) good standing in Tenant’s state of incorporation and (ii) qualification to do business in the State of California.

29.21.    Attorneys’ Fees. In the event that either Landlord or Tenant should bring suit for the possession of the Premises, for the recovery of any sum due under this Lease, or because of the breach of any provision of this Lease or for any other relief against the other, then all costs and expenses, including reasonable attorneys’ fees, incurred by the prevailing party therein shall be paid by the other party, which obligation on the part of the other party shall be deemed to have accrued on the date of the commencement of such action and shall be enforceable whether or not the action is prosecuted to judgment.

29.22.    Governing Law; WAIVER OF TRIAL BY JURY. This Lease shall be construed and enforced in accordance with the laws of the State of California. IN ANY ACTION OR PROCEEDING ARISING HEREFROM, LANDLORD AND TENANT HEREBY CONSENT TO (I) THE JURISDICTION OF ANY COMPETENT COURT WITHIN THE STATE OF CALIFORNIA, (II) SERVICE OF PROCESS BY ANY MEANS AUTHORIZED BY CALIFORNIA LAW, AND (III) IN THE INTEREST OF SAVING TIME AND EXPENSE, TRIAL WITHOUT A JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THE PARTIES HERETO AGAINST THE OTHER OR THEIR SUCCESSORS IN RESPECT OF ANY MATTER ARISING OUT OF OR IN CONNECTION WITH THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT, TENANT’S USE OR OCCUPANCY OF THE PREMISES, AND/OR ANY CLAIM FOR INJURY OR DAMAGE, OR ANY EMERGENCY OR STATUTORY REMEDY. IN THE EVENT LANDLORD COMMENCES ANY SUMMARY PROCEEDINGS OR ACTION FOR NONPAYMENT OF BASE RENT OR ADDITIONAL RENT, TENANT SHALL NOT INTERPOSE ANY COUNTERCLAIM OF ANY NATURE OR DESCRIPTION (UNLESS SUCH COUNTERCLAIM SHALL BE MANDATORY) IN ANY SUCH PROCEEDING OR ACTION, BUT SHALL BE RELEGATED TO AN INDEPENDENT ACTION AT LAW.

60

29.23.    Submission of Lease. Submission of this instrument for examination or signature by Tenant does not constitute a reservation of, option for or option to lease, and it is not effective as a lease or otherwise until execution and delivery by both Landlord and Tenant.

29.24.    Brokers. Landlord and Tenant hereby warrant to each other that they have had no dealings with any real estate broker or agent in connection with the negotiation of this Lease, excepting only the real estate brokers or agents specified in Section 12 of the Summary (the “Brokers”), and that they know of no other real estate broker or agent who is entitled to a commission in connection with this Lease. Each party agrees to indemnify and defend the other party against and hold the other party harmless from any and all claims, demands, losses, liabilities, lawsuits, judgments, costs and expenses (including without limitation reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of any dealings with any real estate broker or agent, other than the Brokers, occurring by, through, or under the indemnifying party. The terms of this Section 29.24 shall survive the expiration or earlier termination of the Lease Term. Landlord shall pay the Brokers pursuant to the terms of separate commission agreements.

29.25.    Independent Covenants. This Lease shall be construed as though the covenants herein between Landlord and Tenant are independent and not dependent and Tenant hereby expressly waives the benefit of any statute to the contrary and agrees that if Landlord fails to perform its obligations set forth herein, Tenant shall not be entitled to make any repairs or perform any acts hereunder at Landlord’s expense or to any setoff of the Rent or other amounts owing hereunder against Landlord.

29.26.    Project or Building Name, Address and Signage. Landlord shall have the right, subject to the remaining terms of this Lease (including, without limitation, Article 23 above), at any time to change the name and/or address of the Project or Building and to install, affix and maintain any and all signs on the exterior and on the interior of the Project (other than the interior of the Premises) as Landlord may, in Landlord’s sole discretion, desire. Tenant shall not use the name of the Project or Building or use pictures or illustrations of the Project or Building in advertising or other publicity or for any purpose other than as the address of the business to be conducted by Tenant in the Premises, without the prior written consent of Landlord, which shall not be unreasonably withheld, conditioned or delayed; provided, however, if Landlord approves of a picture or illustration of the Project or Building (which approval shall not be unreasonably withheld, conditioned or delayed), Tenant may use the same picture or illustration in other advertisements or other publicity provided such advertisements or other publicity does not identify or reference Landlord or any Landlord Party in any manner.

29.27.    Counterparts. This Lease may be executed in counterparts with the same effect as if both parties hereto had executed the same document. Both counterparts shall be construed together and shall constitute a single lease.

29.28.    Confidentiality. Landlord and Tenant acknowledge that the content of this Lease and any related documents are confidential information. Landlord and Tenant shall keep such confidential information strictly confidential and shall not disclose such confidential information to any person or entity other than Landlord’s and Tenant’s respective financial, legal, and space planning consultants. Notwithstanding the foregoing, Landlord or Tenant may disclose the terms

61

of this Lease and any of the other matters described in this Section as follows without violating the confidentiality provision contained in this Section: (i) such disclosures to existing or prospective lenders, purchasers, title companies, appraisers, and other third persons as may reasonably be necessary in order to conduct its business relating to the Project in a commercially reasonable manner; (ii) privileged communications including communications with counsel, accountants, and advisors; (iii) such disclosures as may be necessary or required by any governmental or regulatory authorities; (iv) such disclosures as may be required by law or by subpoena or any other similar court order or discovery request in any civil or criminal; (v) such disclosures as may be reasonably required to enforce the terms of this Lease or any rights and remedies under this Lease; (vi) such disclosures as are necessary in connection with any Transfers or any Permitted Transfers, and (vii) to the extent that disclosure is mandated by applicable law, the Securities Exchange Commission or the rules of any stock exchange upon which Landlord’s or Tenant’s (or Landlord or Tenant’s parent’s) shares are from time to time traded..

29.29.    Development of the Project.

29.29.1.    Subdivision. Landlord reserves the right to subdivide all or a portion of the buildings and Common Areas, provided that no such subdivision shall limit or adversely affect in any material or unreasonable manner any rights of Tenant hereunder and all provisions of this Lease with respect to percentages of parking or space shall be calculated as if the Project had not been subdivided. Tenant agrees to execute and deliver, upon demand by Landlord and in the form requested by Landlord, any additional documents needed to conform this Lease to the circumstances resulting from a subdivision and any all maps in connection therewith. Notwithstanding anything to the contrary set forth in this Lease, the separate ownership of any buildings and/or Common Areas by an entity other than Landlord shall not affect the calculation of Direct Expenses or Tenant’s payment of Tenant’s Share of Direct Expenses.

29.29.2.    Construction of Property and Other Improvements. Tenant acknowledges that portions of the Project may be under construction following Tenant’s occupancy of the Premises, and that such construction may result in levels of noise, dust, obstruction of access, etc. which are in excess of that present in a fully constructed project, provided that any such noise, dust or obstruction shall not unreasonably interfere with Tenant’s use of the Premises for the Permitted Use, access to or from the Premises or Tenant’s parking rights hereunder (except to the extent that Landlord provides Tenant with Reasonable Alternate Parking) or Tenant’s signage rights under Article 23 above. Tenant hereby waives any and all rent offsets or claims of constructive eviction which may arise in connection with such demolition or construction to the extent consistent with the preceding proviso (except as otherwise expressly set forth in Section 19.5.2).

29.30.    No Violation. Tenant hereby warrants and represents that neither its execution of nor performance under this Lease shall cause Tenant to be in violation of any agreement, instrument, contract, law, rule or regulation by which Tenant is bound, and Tenant shall protect, defend, indemnify and hold Landlord harmless against any claims, demands, losses, damages, liabilities, costs and expenses, including, without limitation, reasonable attorneys’ fees and costs, arising from Tenant’s breach of this warranty and representation.

62

29.31.    Transportation Management. If and to the extent require by Applicable Laws, Tenant shall fully comply with all present or future programs intended to manage parking, transportation or traffic in and around the Project and/or the Building, and in connection therewith, Tenant shall take responsible action for the transportation planning and management of all employees located at the Premises by working directly with Landlord, any governmental transportation management organization or any other transportation-related committees or entities. Such programs may include, without limitation: (i) restrictions on the number of peak-hour vehicle trips generated by Tenant; (ii) increased vehicle occupancy; (iii) implementation of an in-house ridesharing program and an employee transportation coordinator; (iv) working with employees and any Project, Building or area-wide ridesharing program manager; (v) instituting employer-sponsored incentives (financial or in-kind) to encourage employees to rideshare; and (vi) utilizing flexible work shifts for employees.

29.32.    Rooftop Rights. Subject to, (i) reasonable construction rules and regulations promulgated by Landlord (Landlord shall deliver a written copy of same to Tenant, as well as written notice of any future modifications thereto), (ii) the Building standards therefor, and (iii) the terms and conditions set forth in Article 8 of this Lease and this Section 29.32, Tenant may install, repair, maintain and use, at Tenant’s sole cost and expense, but without the payment of any Base Rent, Additional Rent (except for electricity and other utility costs) or similar fee or charge, one (1) satellite dish or antenna, with the antenna not to exceed one (1) meter in diameter, on the roof of the Building for the sending and receiving of signals or broadcasts (provided that there shall be no generation or transmission of commercial signals or broadcasts) servicing the business conducted by Tenant from within the Premises (such satellite dishes are collectively defined as the “Rooftop Equipment”). Tenant shall be solely responsible for any and all costs incurred or arising in connection with the Rooftop Equipment, including, but not limited to, costs of electricity and insurance related to the Rooftop Equipment. Landlord makes no representations or warranties whatsoever with respect to the condition of the roof of the Building, or the fitness or suitability of the roof of the Building for the installation, maintenance and operation of the Rooftop Equipment, including, without limitation, with respect to the quality and clarity of any receptions and transmissions to or from the Rooftop Equipment and the presence of any interference with such signals whether emanating from the Building or otherwise. The physical appearance and the size of the Rooftop Equipment shall be subject to Landlord’s reasonable approval, the location of any such Rooftop Equipment shall be mutually agreed upon by Landlord and Tenant, and Landlord may require Tenant to install screening around such Rooftop Equipment, at Tenant’s sole cost and expense, as reasonably designated by Landlord. Tenant shall service, maintain and repair such Rooftop Equipment, at Tenant’s sole cost and expense. In the event Tenant elects to exercise its right to install the Rooftop Equipment, then Tenant shall give Landlord prior notice thereof. Tenant shall reimburse to Landlord the actual and documented out-of-pocket costs reasonably incurred by Landlord in approving such Rooftop Equipment. Tenant’s rights under this Section 29.32 shall terminate and shall be of no further force or effect upon the expiration or earlier termination of this Lease, or, in the event Tenant (or a Permitted Transferee ) no longer occupies the Premises. Prior to the expiration or earlier termination of this Lease, Tenant shall, as promptly as possible but in no event more than thirty (30) days thereafter, remove and restore the affected portion of the rooftop and the Building to the condition the rooftop and the Building would have been in had no such Rooftop Equipment been installed (reasonable wear and tear and damage from casualty excepted). Such Rooftop Equipment shall be installed pursuant to plans and specifications approved by Landlord (specifically including, without limitation, all mounting and waterproofing

63

details), which approval will not be unreasonably withheld, conditioned, or delayed. Notwithstanding any such review or approval by Landlord, Tenant shall remain solely liable for any damage arising in connection with Tenant’s installation, use, maintenance and/or repair of such Rooftop Equipment, including, without limitation, any damage to a portion of the roof or roof membrane and any penetrations to the roof. Landlord and Tenant hereby acknowledge and agree that Landlord shall have no liability in connection with Tenant’s use, maintenance and/or repair of such Rooftop Equipment. Tenant shall be responsible, at Tenant’s sole cost and expense, for (i) obtaining all permits or other governmental approvals required in connection with the Rooftop Equipment, and (ii) installing, repairing and maintaining and causing the Rooftop Equipment to comply with all Applicable Laws. Tenant shall not be entitled to license its Rooftop Equipment to any third party, nor shall Tenant be permitted to receive any revenues, fees or any other consideration for the use of such Rooftop Equipment by a third party.
