ARTICLE 1

PREMISES, BUILDING, PROJECT, AND COMMON AREAS

1.1 Premises, Building, Project and Common Areas.

1.1.1 The Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the premises set forth in Section 2.2 of the Summary (the “Premises”). The outline of the Premises is set forth in Exhibit A attached hereto and contains approximately the number of rentable square feet as set forth in Section 2.2 of the Summary. The parties hereto agree that the lease of the Premises is upon and subject to the terms, covenants and conditions (the “TCCs”) 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 TCCs 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 in the “Building,” as that term is defined in Section 1.1.2, below, 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 Work Letter attached hereto as Exhibit B (the “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 Work Letter. 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 only to (i) Landlord’s obligations under the Work Letter with respect to a list of punchlist items prepared by Landlord and Tenant in accordance therewith, (ii) latent defects as well as defects in the mechanical, electrical and plumbing systems brought to Landlord’s attention in writing within one (1) year following Landlord’s delivery of the Premises to Tenant, (iii) Landlord’s obligations set forth in Article 7 of this Lease, (iv) Landlord’s obligations set forth in Article 24 of this Lease, and (v) Landlord’s obligations set forth in Section 29.33 of this Lease. To the actual knowledge of Mrs. Kathleen Bristol (Landlord’s Asset Manager with respect to the Project), Mr. Brian Galligan (Landlord’s Vice President of Asset Management) and Ms. Theresa Amos (Property Manager of the Building), without any duty of investigation or any duty of inquiry, Landlord has not, as of the Effective Date, received from any applicable governmental agency any written notice (a “Violation Notice”) of violation or violations (or claim thereof) relating to Applicable Laws, or applicable zoning, ordinances, building codes or CC&Rs with regard to the Premises or the Building existing as of the Effective Date; provided, however, the foregoing representation does not apply with respect to any alterations, additions or improvements made (or to be made) by Tenant. Landlord represents and warrants that, as of the Effective Date and as it pertains to Landlord’s organization, the three (3) individuals listed above are the suitable individuals as it relates to knowledge of the Premises. If Landlord receives any Violation Notice at any time after the Effective Date, Landlord shall promptly deliver a copy of

such Violation Notice to Tenant. In the event of a conflict between the terms set forth in the Summary and the TCCs of the body of this Lease, the latter shall control.

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 project known as “Pacific Corporate Center.” The term “Project,” as used in this Lease, shall mean (i) the Building and the Common Areas, and (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 other office building located adjacent to the Building and the land upon which such adjacent office building is located.

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 designated by Landlord, in its discretion, including certain areas designated for the exclusive use of certain tenants [such as those areas reserved for the exclusive use of the tenant leasing the balance of the Building, which areas are identified as “Tanvex Exclusive Areas” on the attached Exhibit A-2], or to otherwise be shared by Landlord and certain tenants, 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 designated as such by Landlord. The manner in which the Common Areas are maintained and operated shall be at the sole discretion of Landlord, provided that Landlord shall maintain and operate the same in a manner consistent with that of other Comparable Buildings (as that term is defined in Exhibit H attached hereto) and the use thereof shall be subject to such rules, regulations and restrictions as Landlord may make from time to time, provided that such rules, regulations and restrictions do not unreasonably interfere with the rights granted to Tenant under this Lease and the Permitted Use (as that term is defined in Section 7 of the Summary and as set forth in Section 5.1, below). Upon reasonable prior written notice to Tenant (except in the event of emergencies) 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 no such changes shall be permitted which materially reduce Tenant’s rights or access hereunder. Except when and where Tenant’s right of access is specifically excluded in this Lease, Tenant shall have the right of access to the Premises, the Building, and the Project parking facility twenty-four (24) hours per day, seven (7) days per week during the “Lease Term,” as that term is defined in Section 2.1, below.

1.2 Stipulation of Rentable Square Feet of Premises. For purposes of this Lease, “rentable square feet” of the Premises shall be deemed as set forth in Section 2.2 of the Summary.

ARTICLE 2

LEASE TERM; TERMINATION RIGHT, OPTION TERM

2.1 Initial Lease Term. The TCCs and provisions of this Lease shall be effective as of the Effective Date. 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; provided, however, the Lease Commencement Date and the Lease Expiration Date shall be subject to tolling as more particularly set forth in Section 5.2 of the Tenant Work Letter. 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 Lease Year shall commence on the Lease Commencement Date (e.g., August 16, 2011, as previously scheduled) and end on the last day of the month in which the first anniversary of the Lease Commencement Date occurs (e.g., August 31, 2012, as previously scheduled), and the second and each succeeding Lease Year shall commence on the first day of the next calendar month; 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 factually correct notice in 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 five (5) days of receipt thereof to the extent such notice is factually correct.

2.2 Tenant Termination Right. Notwithstanding any provision to the contrary contained in this Lease, Tenant shall have the right to terminate and cancel this Lease in its entirety effective as of either August 31, 2012, August 31, 2013, August 31, 2014 or August 31, 2015 (as applicable, the “Termination Date”), upon Tenant’s delivery of written notice to Landlord (the “Termination Notice”), which notice shall be delivered to Landlord on or before the date which is six (6) full calendar months prior to the subject Termination Date, and, concurrently with its delivery of such Termination Notice, Tenant shall deliver to Landlord the “Termination Fee,’’ as that term is defined hereinbelow, as consideration for and as a condition precedent to such early termination. The “Termination Fee” shall be equal to either (A) Four Hundred Forty-Two Thousand Seven Hundred Eighty One and No/100 Dollars ($442,781.00) in connection with an August 31, 2012 termination, (B) Three Hundred Thirty-Two Thousand Eighty-Six and No/100 Dollars ($332,086.00) in connection with an August 31, 2013 termination, (C) Two Hundred Twenty-One Thousand Three Hundred Ninety and No/100 Dollars ($221,390.00) in connection with an August 31, 2014 termination, or (D) One Hundred Ten Thousand Six Hundred Ninety-Six and No/100 Dollars ($110,696.00) in connection with an August 31, 2015 termination. Subject to Landlord’s timely receipt of the Termination Notice and the corresponding Termination Fee, this Lease shall automatically terminate and be of no further force or effect as of the Termination Date, and Landlord and Tenant shall be relieved of their respective obligations under this Lease, as of the Termination Date, except with respect to those obligations set forth in this Lease, which specifically survive the expiration or earlier termination of this Lease, including, without limitation, the payment by Tenant of all amounts owed by Tenant under this Lease, up to and including the Termination Date. The termination right granted to Tenant under this Section 2.2 shall automatically terminate and be of no further force or effect in the event (w) Tenant fails to properly and timely exercise such termination right as set forth in

this Section 2.2, (x) Tenant assigns or subleases all or essentially all of the Premises for all or essentially all of the then-remaining Lease Term to entities or persons other than “Permitted Transferees” (as that term is defined in Section 14.8, below), (y) Tenant’s right to possession of the Premises has previously been terminated pursuant to Section 19.2 of this Lease, or (z) Tenant is in “Economic Default” (as defined in Section 2.3.2, below) under this Lease (beyond any applicable notice and cure periods), as of the date of Tenant’s delivery of the Termination Notice to Landlord or, at Landlord’s election, as of the Termination Date. The termination right granted to Tenant under this Section 2.2 is personal to the Tenant named in this Lease (the “Original Tenant”), and any Permitted Transferee, and may not be exercised by any other assignee, sublessee, or transferee of the Original Tenant’s interest in this Lease.

2.3 Option Term(s).

2.3.1 Option Right. Landlord hereby grants the Original Tenant and its Permitted Transferees one (1) option to extend the Lease Term for the entire Premises by a period of five (5) years (the “Option Term”). Such option shall be exercisable only by Notice delivered by Tenant to Landlord as provided below, provided that, as of the date of delivery of such Notice, (i) Tenant is not then in “Economic Default” or “Material Non-Economic Default” under this Lease (beyond the applicable notice and cure periods), and (ii) Tenant has not been in Economic Default or Material Non-Economic Default under this Lease (beyond the applicable notice and cure periods) more than twice during the prior twenty-four (24) month period. Upon the proper exercise of such option to extend, and provided that, as of the end of the Lease Term, (A) Tenant is not in Economic Default or Material Non-Economic Default under this Lease (beyond the applicable notice and cure periods), and (B) Tenant has not been in Economic Default or Material Non-Economic Default under this Lease (beyond the applicable notice and cure periods) more than twice during the prior twenty-four (24) month period, then the Lease Term, as it applies to the entire Premises, shall be extended for a period of five (5) years. The rights contained in this Section 2.3 shall only be exercised by the Original Tenant or its Permitted Transferee (and not any other assignee, sublessee or other transferee of the Original Tenant’s interest in this Lease) if Original Tenant and/or its Permitted Transferee is in occupancy of not less than fifty percent (50%) of the Premises. For purposes hereof, an “Economic Default” shall mean any default contemplated by the terms of Section 19.1.1 of this Lease, and a “Material Non-Economic Default” shall mean any of the defaults identified in Sections 19.1.3 through 19.1.6 of this Lease; provided, however, that in no event shall (1) any one circumstance (e.g. an instance of failed rent payment, a failure to timely complete an estoppel certificate, a failure to comply with CC&Rs, etc.) result in, or constitute, more than one Economic Default or Material Non-Economic Default, and/or (2) any circumstance be deemed an Economic Default or Material Non-Economic Default under this Section 2.3.1 to the extent such matter has been reasonably disputed in accordance with the TCCs of this Lease by Tenant and remains unresolved.

2.3.2 Option Rent. The Rent payable by Tenant during the Option Terms (the “Option Rent”) shall be equal to the “Market Rent,” as that term is defined in, and determined pursuant to, Exhibit H attached hereto, which Market Rent shall include annual escalations in connection with such Market Rent determination. The calculation of the Market Rent shall be derived from a review of, and comparison to, the “Net Equivalent Lease Rates” of the “Comparable Transactions,” as provided for in Exhibit H.

2.3.3 Exercise of Option. The option contained in this Section 2.3 shall be exercised by Tenant, if at all, only in the manner set forth in this Section 2.3. Tenant shall deliver notice (the “Exercise Notice”) to Landlord not more than twelve (12) months nor less than nine (9) months prior to the expiration of the initial Lease Term, stating that Tenant is exercising its option. Concurrently with such Exercise Notice, Tenant shall deliver to Landlord Tenant’s calculation of the Market Rent (the “Tenant’s Option Rent Calculation”). Landlord shall deliver notice (the “Landlord Response Notice”) to Tenant on or before the date which is thirty (30) days after Landlord’s receipt of the Exercise Notice and Tenant’s Option Rent Calculation (the “Landlord Response Date”), stating that (A) Landlord is accepting Tenant’s Option Rent Calculation as the Market Rent, or (B) rejecting Tenant’s Option Rent Calculation and setting forth Landlord’s calculation of the Market Rent (the “Landlord’s Option Rent Calculation”). Within ten (10) business days of its receipt of the Landlord Response Notice, Tenant may, at its option, accept the Market Rent contained in the Landlord’s Option Rent Calculation. If Tenant does not affirmatively accept or Tenant rejects the Market Rent specified in the Landlord’s Option Rent Calculation, the parties shall follow the procedure set forth in Section 2.3.4 below, and the Market Rent shall be determined in accordance with the terms of Section 2.3.4 below.

2.3.4 Determination of Market Rent. In the event Tenant objects or is deemed to have objected to the Market Rent, Landlord and Tenant shall attempt to agree upon the Market Rent using reasonable good-faith efforts. If Landlord and Tenant fail to reach agreement within sixty (60) days following Tenant’s objection or deemed objection to the Landlord’s Option Rent Calculation (the “Outside Agreement Date”), then, within two (2) business days following such Outside Agreement Date, (x) Landlord may re-calculate the Landlord’s Option Rent Calculation by delivering written notice thereof to Tenant, and (y) Tenant may re-calculate the Tenant’s Option Rent Calculation by delivering written notice thereof to Tenant. If Landlord and Tenant thereafter fail to reach agreement within seven (7) business days of the Outside Agreement Date, then in connection with the Option Rent, Landlord’s Option Rent Calculation and Tenant’s Option Rent Calculation, each as most recently delivered to the other party pursuant to the TCCs of this Section 2.3, shall be submitted to the “Neutral Arbitrator,” as that term is defined in Section 2.3.4.1 of this Lease, pursuant to the TCCs of this Section 2.3.4. The submittals shall be made concurrently with the selection of the Neutral Arbitrator pursuant to this Section 2.3.4 and shall be submitted to arbitration in accordance with Section 2.3.4.1 through 2.3.4.5 of this Lease, but subject to the conditions, when appropriate, of Section 2.3.3.

2.3.4.1 Landlord and Tenant shall mutually and reasonably agree on the appointment of one (1) arbitrator who shall by profession be 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 first-class commercial properties in the Comparable Area (the “Neutral Arbitrator”). The determination of the Neutral Arbitrator shall be limited solely to the issue of whether Landlord’s Option Rent Calculation or Tenant’s Option Rent Calculation, each as submitted to the Neutral Arbitrator pursuant to Section 2.2.4, above, is the closest to the actual Market Rent as determined by such Neutral Arbitrator, taking into account the requirements of Section 2.2.2 of this Lease. Such Neutral Arbitrator shall be appointed within fifteen (15) days after the applicable Outside Agreement Date. Neither the Landlord or Tenant or either party’s arbitrator may, directly or indirectly, consult with the Neutral Arbitrator prior to, 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.

2.3.4.2 The Neutral Arbitrator shall, within thirty (30) days of his/her appointment, reach a decision as to Market Rent and determine whether the Landlord’s Option Rent Calculation or Tenant’s Option Rent Calculation, each as submitted to the Neutral Arbitrator pursuant to Section 2.2.4, above, is closest to Market Rent as determined by such Neutral Arbitrator and simultaneously publish a ruling (“Award”) indicating whether Landlord’s Option Rent Calculation or Tenant’s Option Rent Calculation is closest to the Market Rent as determined by such Neutral Arbitrator. Following notification of the Award, the Landlord’s Option Rent Calculation or Tenant’s Option Rent Calculation, whichever is selected by the Neutral Arbitrator as being closest to Market Rent, shall become the then applicable Option Rent.

2.3.4.3 The Award issued by such Neutral Arbitrator shall be binding upon Landlord and Tenant.

2.3.4.4 If Landlord and Tenant fail to appoint the Neutral Arbitrator within fifteen (15) days after the applicable Outside Agreement Date, either party may petition the presiding judge of the Superior Court of San Diego County to appoint such Neutral Arbitrator subject to the criteria in Section 2.2.4.1 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 Neutral Arbitrator.

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

ARTICLE 3

BASE RENT

3.1 In General. Tenant shall pay, without prior notice or demand, to Landlord or Landlord’s agent at the management office of the Project, or, 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 (unless and to the extent otherwise expressly set forth in this Lease). In connection with the designated place for payment identified in the preceding sentence, to the extent Landlord elects to effectuate any change in location for such payment, Landlord shall deliver written notice setting forth such newly designated place no less than fifteen (15) days in advance of the due date of the first such payment of Base Rent following such re-designation. The Base Rent for the first full month of the Lease Term which occurs after the expiration of any free rent period 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 such fractional month shall accrue on a daily basis during such fractional month and shall

total an amount equal to the product of (i) a fraction, the numerator of which is the number of days in such fractional month and the denominator of which is the actual number of days occurring in such calendar month, and (ii) the then-applicable Monthly Installment of Base Rent. All other payments or adjustments required to be made under the TCCs of this Lease that require proration on a time basis shall be prorated on the same basis.

3.2 Abated Base Rent. Notwithstanding any contrary provisions set forth in this Article 3 and in Section 4 of the Summary, Tenant shall not be obligated to pay (and therefore shall not pay) the monthly installments of Base Rent attributable to the Premises (the “Base Rent Abatement”) for the six (6) month period commencing on November 1, 2011 and ending on April 30, 2012 (the “Base Rent Abatement Period”). In connection with the foregoing, the Base Rent Abatement provided to Tenant pursuant to this Section 3.2 during the Base Rent Abatement Period shall not exceed an aggregate of Two Hundred Twenty-Four Thousand Six Hundred Twenty-Eight and 48/100 Dollars ($224,628.48). Tenant acknowledges and agrees that during such Base Rent Abatement Period, such abatement of Base Rent shall have no effect on the calculation of any Direct Expenses payable by Tenant pursuant to the terms of this Lease, which any Direct Expenses shall be payable during the Base Rent Abatement Period without regard to the Base Rent Abatement. Additionally, notwithstanding the foregoing, Tenant shall be obligated to pay all “Additional Rent,’’ as that term is defined in Section 4.1, below, during the Base Rent Abatement Period. The foregoing Base Rent Abatement has been agreed to by Landlord and Tenant as additional consideration for entering into this Lease, and for Tenant’s agreement to pay the rent and for the parties to perform the terms and conditions otherwise required under this Lease. If Tenant shall be in Economic Default of this Lease and shall fail to cure such default within any applicable notice and cure period, then Landlord may elect at its option, by notice to Tenant and in addition to any other remedies Landlord may have under this Lease, that the dollar amount of the unapplied portion of such Base Rent Abatement as of such default shall be converted to a credit to be applied to the Base Rent applicable to the Premises at the end of the Lease Term and Tenant shall immediately be obligated to begin paying Base Rent for the Premises in full; provided however, to the extent the Lease is terminated pursuant to the provisions of Article 19, below, then as a part of the recovery set forth in Section 19.2, below, Landlord shall be entitled to recover the then-unamortized portion of the monthly Base Rent that was abated under the provisions of this Section 3.2, which Base Rent Abatement shall be amortized on a level payment basis over a period of sixty (60) months, employing an interest factor of zero percent (0%).

If the Project is not at least one hundred percent (100%) occupied during all or a portion of any Expense Year, Landlord may elect to make an appropriate adjustment to the components of Operating Expenses for such year to determine the amount of Operating Expenses that would have been incurred had the Project been one hundred percent (100%) occupied; and the amount so determined shall be deemed to have been the amount of Operating Expenses for such year.

Landlord’s determination of Operating Expenses shall take into account and adjust for all cash discounts, trade discounts, or quantity discounts as and when actually received by Landlord in connection with the purchase of any goods, services or utilities in connection with the operation of the Project.

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 included by Landlord as Building Tax Expenses pursuant to the TCCs of this Lease.

4.2.6 “Tenant’s Share” shall mean the percentage set forth in Section 6 of the Summary. Tenant’s Share is stated as a percentage calculated as a fraction where the numerator equals the number of rentable square feet of the Premises and the denominator is the 75,745 rentable square feet in the Building.

4.2.7 “Utilities Costs” shall mean all actual charges for utilities for the Building and the Project which Landlord shall pay during any Expense Year, including, but not limited to, the costs of water, sewer and electricity, and the costs of HVAC and other utilities (but excluding (i) the cost of electricity consumed in any area of the Project that is not part of the Common Areas (i.e., excluding the Premises, the premises of other tenants of the Building and any other buildings in the Project, and other leasable space throughout the Project that is not then occupied by a tenant, (since Tenant is separately paying for the cost of electricity pursuant to Section 6.1 below) and (ii) those charges for which tenants directly reimburse Landlord or otherwise pay directly to the utility company) as well as related fees, assessments and surcharges. Tenant’s Share of Utilities Costs shall be calculated assuming the Buildings are one hundred percent ( 100%) occupied. Utilities Costs shall include any costs of utilities which are allocated to the Real Property under any declaration, restrictive covenant, or other instrument pertaining to the sharing of costs by the Real Property or any portion thereof, including any covenants, conditions or restrictions now or hereafter recorded against or affecting the Real Property.

4.3 Allocation of Direct Expenses. 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 tenants of the Building and the tenants of the other buildings in the Project. Accordingly, as set forth in Section 4.2 above, Direct Expenses (which consists of Operating Expenses, Tax Expenses and Utilities Costs) 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 tenants of the Building (as opposed to the tenants of any other buildings in the Project) and such portion shall be the Direct Expenses for purposes of this Lease. Such portion of Direct Expenses allocated to the tenants of 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.

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 give to Tenant following the end of each Expense Year, a statement (the “Statement”) which shall state in general major categories the Direct Expenses incurred or accrued for such preceding Expense Year, and which shall indicate the amount of Tenant’s Share of Direct Expenses. Landlord shall use commercially reasonable efforts to deliver such Statement to Tenant on or before April 15 following the end of the Expense Year to which such Statement relates. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, Tenant shall pay, within thirty (30) days after receipt of the Statement, 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 (an “Excess”), Tenant shall receive a credit in the amount of such Excess 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, if Tenant’s Share of Direct Expenses is greater than the amount of Estimated Direct Expenses previously paid by Tenant to Landlord, Tenant shall, within thirty (30) days after receipt of the Statement, pay to Landlord such amount, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses (again, an Excess), Landlord shall, within thirty (30) days, deliver a check payable to Tenant in the amount of such Excess. 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 nine (9) months after the Lease Expiration Date, provided that in any event Tenant shall be responsible for Tenant’s Share of Direct Expenses levied by any governmental authority or by any public utility companies at any time following the Lease Expiration Date which are attributable to any Expense Year.

4.4.2 Statement of Estimated Direct Expenses. In addition, Landlord shall give Tenant a yearly expense estimate statement (the “Estimate Statement”) which shall set forth in general major categories 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”). Landlord shall use commercially reasonable efforts to deliver such Estimate Statement to Tenant on or before April 15 following the end of the Expense Year to which such Estimate Statement relates. 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, within thirty (30) days after receipt of the Estimate Statement, a fraction of the Estimated Direct Expenses for the then-current Expense Year (reduced by any amounts paid pursuant to the second to 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), 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. Throughout the Lease Term Landlord shall maintain books and records with respect to Direct Expenses in accordance with generally accepted real estate accounting and management practices, consistently applied.

4.5 Taxes and Other Charges for Which Tenant Is Directly Responsible.

4.5.1 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 to the extent resulting from such increase in the assessment, as the case may be.

4.5.2 If the Improvements in the Premises, whether installed and/or paid for by Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof, are assessed for real property tax purposes at a valuation higher than the valuation at which tenant improvements conforming to Landlord’s “building standard” in other space in the Building are assessed, then the Tax Expenses levied against Landlord or the property by reason of such excess assessed valuation shall be deemed to be taxes levied against personal property of Tenant and shall be governed by the provisions of Section 4.5.1, above.

4.5.3 Notwithstanding any contrary provision herein, Tenant shall pay prior to delinquency any (i) rent tax or sales tax, service tax, transfer tax or value added tax, or any other applicable tax on the rent or services herein or otherwise respecting this Lease, (ii) taxes assessed

upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion of the Project, including the Project parking facility; or (iii) taxes assessed upon this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the Premises.

4.6 Landlord’s Books and Records. Upon Tenant’s written request given not more than ninety (90) days 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 cure period provided in this Lease, Landlord shall furnish Tenant with such reasonable supporting documentation in connection with said Direct Expenses as Tenant may reasonably request. Landlord shall provide said information to Tenant within sixty (60) days after Tenant’s written request therefor. Within one hundred eighty ( 180) days after receipt of a Statement by Tenant (the “Review Period”), if Tenant disputes the amount of Additional Rent set forth in the Statement, an independent certified public accountant (which accountant (A) is a member of a nationally or regionally recognized accounting firm, and (B) is not working on a contingency fee basis), designated and paid for by Tenant, may, after reasonable notice to Landlord and at reasonable times, inspect Landlord’s records with respect to the Statement at Landlord’s offices, provided that Tenant is not then in default under this Lease (beyond any applicable notice and cure periods) and Tenant has paid all amounts required to be paid under the applicable Estimate Statement and Statement, as the case may be. In connection with such inspection, Tenant and Tenant’s agents must agree in advance to follow Landlord’s reasonable rules and procedures regarding inspections of Landlord’s records, and shall execute a commercially reasonable confidentiality agreement regarding such inspection. Tenant’s failure to dispute the amount of Additional Rent set forth in any Statement within the Review Period shall be deemed to be Tenant’s approval of such Statement and Tenant, thereafter, waives the right or ability to dispute the amounts set forth in such Statement. If after such inspection, Tenant still disputes such Additional Rent, a determination as to 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 determination by the Accountant proves that Direct Expenses were overstated by more than four percent (4%), then the cost of the Accountant and the cost of such determination shall be paid for by Landlord. Tenant hereby acknowledges that Tenant’s sole right to inspect Landlord’s books and 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 inspect such books and records and/or to contest the amount of Direct Expenses payable by Tenant.

Tenant shall not do or permit anything to be done in or about the Premises which will in any way obstruct or interfere with the rights of other tenants or occupants of the Building, 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.

Subject to the terms of the immediately preceding sentence, Landlord shall have the right to require Tenant to execute and acknowledge, within fifteen ( 15) business days of a request by Landlord, a “Recognition of Covenants, Conditions, and Restriction,” in a form substantially similar to that attached hereto as Exhibit F, agreeing to and acknowledging the CC&Rs.

Tenant acknowledges that such Building elevator is under Tanvex’s control (as opposed to Landlord’s control), and Tenant hereby acknowledges that Landlord has made no representation or warranty to Tenant with respect to the probability of obtaining Tanvex’s consent to Tenant’s use of such elevator for all, or any of the time periods identified hereinabove. In the event that Landlord is unable to obtain Tanvex’s consent to Tenant’s use of the elevator (or if Landlord is unable to obtain Tanvex’s consent to Tenant’s use of the elevator for all or any of the time periods identified hereinabove), Tenant’s and Landlord’s rights and obligations under the remaining terms and conditions of the Lease shall be unaffected.

6.5.3 Notwithstanding anything to the contrary set forth in Section 4.2.4 or this Article 6, Tenant shall directly pay to Landlord one hundred percent (100%) of the total cost (including any permitting and/or other implementation costs) of providing all services (and related equipment) affirmatively requested and required by Tenant which are in excess of the Building-standard services to be provided by Landlord hereunder , including, but not limited to, any security services for the Project, (ii) any janitorial services to the Premises or above-standard janitorial services in any Common Areas, (iii) day-porter service, and (iv) parking management systems, equipment and/or personnel; provided, however, to the extent Tenant requests in advance from Landlord the cost of providing any such services, Tenant shall only be obligated to reimburse Landlord up to the amount so quoted.

Except and to the extent expressly set forth in Section 6.7, below, 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 beyond Landlord’s reasonable control; 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, Land lord 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.

6.7 Abatement Event. If (i) Landlord fails to perform the obligations required of Landlord under the TCCs of this Lease or to otherwise perform an act required by Landlord to avoid such interference, and (ii) such failure causes all or a portion of the Premises to be untenantable and unusable by Tenant, and (iii) such failure related to (A) the nonfunctioning of any Building System or utility service to the Premises, or (B) a failure to provide access to the Premises, Tenant shall give Landlord notice (the “Initial Notice”), specifying such failure to

perform by Landlord (the “Abatement Event”). If Landlord has not cured such Abatement Event within three (3) business days after the receipt of the Initial Notice (the “Eligibility Period”), Tenant may deliver an additional notice to Landlord (the “Additional Notice”), specifying such Abatement Event and Tenant’s intention to abate the payment of Rent under this Lease. If Landlord does not cure such Abatement Event within two (2) business days of receipt of the Additional Notice, Tenant may, upon written notice to Landlord, immediately abate Rent payable under this Lease for that portion of the Premises rendered untenantable and not used by Tenant, for the period beginning on the date five (5) business days after the Initial Notice to the earlier of the date Landlord cures such Abatement Event or the date Tenant recommences the use of such portion of the Premises (or as to all of the Premises, if the portion which is untenantable materially impairs Tenant’s ability to conduct business from the Premises). Such right to abate Rent shall be Tenant’s sole and exclusive remedy at law or in equity for an Abatement Event. Except as otherwise provided in this Lease, nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder.

ARTICLE 7

REPAIRS

During the entire Lease Term, Landlord shall maintain in first-class condition and operating order and keep in good repair and condition the structural portions of the Building, including without limitation the foundation, floor/ceiling slabs, roof structure (as opposed to roof membrane), curtain wall, exterior glass and mullions, columns, beams, shafts (including elevator shafts), stairs, stairwells, elevator cab, men’s and women’s washrooms, Building mechanical, electrical and telephone closets, and all common and public areas servicing the Building, including the parking areas, landscaping and exterior Project signage (collectively, “Building Structure”) and the Base Building mechanical, electrical, life safety, building access, plumbing , sprinkler systems and HVAC systems (other than the Tenant Maintained Systems) (collectively, the “Building Systems”) and the Project Common Areas. Without modifying Landlord’s obligations set forth above, pursuant to the terms of Section 1.1.1 of this Lease, Landlord shall promptly cure any latent defects in the Premises brought to Landlord’s attention in writing within one (I ) year following Landlord’s delivery of the Premises to Tenant. In addition, Landlord hereby warrants that the Building Systems (exclusive of Tenant Maintained Systems, but including without limitation all other mechanical, electrical, life safety, building access, plumbing, sprinkler systems and HVAC systems in the Premises and not included within the definition of Building Systems) are, as of the Effective Date, in reasonably good working order and condition for Permitted Use, and that any actual defects thereto (excluding de minimus defects) brought to Landlord’s attention in writing within one (1) year following Landlord’s delivery of the Premises to Tenant, shall be repaired or replaced (to the extent reasonably necessary) by Landlord, at Landlord’s sole cost and expense (i.e., not to be included as an Operating Expense), but only to the extent such defects were not caused or otherwise contributed to by Tenant; provided, however, and except to the extent resulting directly from the particular nature of Tenant’s tissue culture room and rodent vivarium uses, in no event shall Tenant’s use of the Premises for the Permitted Use in the ordinary course of business be deemed to be a cause or contributing factor to any defects. Notwithstanding anything in this Lease to the contrary, Tenant shall be required to repair the Building Structure and/or the Building Systems to the extent caused by Tenant’s use of the Premises for other than the Permitted Use (but which for

purposes of this provision shall not apply to the extent resulting directly from particular nature of Tenant’s tissue culture room and rodent vivarium uses), unless and to the extent such damage is covered by insurance carried or required to be carried by Landlord pursuant to Article 10 and to which the waiver of subrogation is applicable (such foregoing obligations will hereinafter be defined as the “BS/BS Exception”). Tenant shall, at Tenant’s own expense, keep the Premises, including all improvements, fixtures and furnishings therein, in good order, repair and condition at all times during the Lease Term, but such obligation shall not extend to the Building Structure and the Building Systems except pursuant to the BS/BS Exception. In addition, Tenant shall, at Tenant’s own expense, but under the supervision and subject to the prior approval of Landlord, 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 (but such obligation shall not extend to the Building Structure and the Building Systems except pursuant to the BS/BS Exception) except for damage caused by ordinary wear and tear or beyond the reasonable control of Tenant; provided however, that if Tenant fails to make such repairs, Landlord may, after written notice to Tenant and Tenant’s failure to repair within ten (10) business days thereafter, but need not, make such repairs and replacements, and Tenant shall pay Landlord’s out-of-pocket cost in direct connection therewith, 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 to the extent arising from Landlord’s involvement with such repairs and replacements upon receipt of a reasonably detailed invoice for same. Subject to 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; provided, however, except for (i) emergencies, or (ii) repairs, alterations, improvements or additions required by governmental or quasi-governmental authorities or court order or decree, any such entry into the Premises by Landlord shall be performed in a manner so as not to materially interfere with Tenant’s use of, or access to, the Premises; provided that, with respect to item (ii) above, Landlord shall use commercially reasonable efforts to not materially interfere with Tenant’s use of, or access to, the Premises. Tenant hereby waives any and all rights under and benefits of subsection l 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.

ARTICLE 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 HYAC 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 fifteen (15) business 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. 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 do not (i) adversely affect the systems and equipment of the Building, exterior appearance of the Building, or structural aspects of the Building, or adversely affect the value of the Premises or Building (the “Cosmetic Alterations”). The construction of the initial improvements to the Premises shall be governed by the terms of the 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 reasonably necessary to protect the Building Structure and/or Building Systems, including, but not limited to, the requirement that Tenant utilize for such purposes only contractors reasonably approved by Landlord. Upon Landlord’s timely request (as more particularly set forth in Section 8.5, below), Tenant shall, at Tenant’s expense, remove any Alterations upon the expiration or any early termination of the Lease Term and return the affected portion of the Premises to its condition as of the Effective Date. 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 of San Diego, all in conformance with Landlord’s construction rules and regulations; provided, however, that prior to commencing to construct any Alteration, Tenant shall meet with Landlord to discuss Landlord’s design parameters and code compliance issues. In the event Tenant performs any Alterations in the Premises which require or give rise to governmentally required changes to the “Base Building,” as that term is defined below, then Landlord shall, at Tenant’s expense, make such changes to the Base Building. The “Base Building” shall include the structural portions of the Building, and the public restrooms, elevators, exit stairwells and the systems and equipment located in the internal core of the Building on the floor or floors on which the Premises are located. In performing the work of any such Alterations, Tenant shall have the work performed in such manner so as not to obstruct access to the Project or any portion thereof, by any other tenant of the Project, and so as not to obstruct the business of Landlord or other tenants in the Project. 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. 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 3093 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, to the extent applicable, 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 payment is made directly to contractors, Tenant shall (i) comply with Landlord’s requirements for final lien releases and waivers in connection with Tenant’s payment for work to contractors, and (ii) sign Landlord’s standard contractor’s rules and regulations. If Tenant orders any work directly from Landlord, Tenant shall pay to Landlord an amount mutually agreed upon in advance by Landlord and Tenant to compensate Landlord for all overhead, general conditions, fees and other costs and expenses arising from Landlord’s involvement with such work; provided, however, to the extent that Tenant, prior to

ordering such working directly from Landlord, requests in writing that Landlord provide Tenant with a pre-review estimate of the costs to be incurred by Landlord in connection with such review, then such costs shall be subject to the reasonable pre-approval of Tenant. 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, Landlord may, in its reasonable discretion, 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. Landlord and Tenant hereby acknowledge and agree that (i) all Alterations, improvements, fixtures, equipment and/or appurtenances which Tenant may have 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 part of the Premises and the property of Landlord, and (ii) the Improvements to be constructed in the Premises pursuant to the TCCs of the Work Letter shall, upon completion of the same, be and become a part of the Premises and the property of Landlord. Furthermore, 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 (as opposed to the Improvements being constructed pursuant to the Work Letter, which Improvements Tenant shall not be required to remove unless otherwise expressly identified by Landlord at the time of approval in accordance with the terms set forth in Section 2.4 of the Work Letter), and to repair any damage to the Premises and Building caused by such removal and return the affected portion of the Premises to the condition existing immediately prior to the performance of the subject Alterations; provided, however, if, in connection with its notice to Landlord with respect to any such Alterations or Cosmetic Alterations, (x) Tenant requests Landlord’s decision with regard to the removal of such Alterations or Cosmetic Alterations, and (y) Landlord thereafter agrees in writing to waive the removal requirement with regard to such Alterations or Cosmetic Alterations, then Tenant shall not be required to so remove such Alterations or Cosmetic Alterations; provided further, however, that if Tenant requests such a determination from Landlord and Landlord, within ten (10) business days following Landlord’s receipt of such request from Tenant with respect to Alterations or Cosmetic Alterations, fails to address the removal requirement with regard to such Alterations or Cosmetic Alterations, Landlord shall be deemed to have agreed to waive the removal requirement with regard to such Alterations or Cosmetic Alterations. If Tenant fails to complete such removal and/or to repair any damage caused by the removal of any Alterations or improvements in the Premises, and returns the affected portion of the Premises to the condition existing immediately prior to the performance of the subject Alterations, then at Landlord’s option Landlord may do so and may charge the cost thereof to Tenant. Except to the extent of Landlord’s negligence or willful misconduct, 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.

8.6 Exceptions to Landlord’s Property. Landlord and Tenant hereby acknowledge and agree that Tenant shall maintain ownership of, and be permitted to remove upon the expiration or earlier termination of this Lease (subject to the repair provisions set forth in Section 8.5, above), any equipment installed or placed in, or about, or affixed to the Premises, but only to the extent such equipment was paid for in its entirety by Tenant.

8.7 One Pass Air. Landlord acknowledges that during the Lease Term Tenant may desire to install a supplemental HVAC (i.e., “One-Pass Air System”) in the tissue culture room, rodent vivarium and/or other specialty lab space in the Premises, which Alterations are, in concept, pre-approved. Notwithstanding the foregoing, the parties acknowledge and agree that in the event that Tenant desires any such One-Pass Air System in the Premises, the plans and specifications related thereto (including, without limitation, related to the size, location, venting, and structural components) shall remain subject to Landlord’s prior written consent, which consent shall not be unreasonably withheld by Landlord, provided it shall be deemed reasonable for Landlord to withhold its consent to any portion of the One-Pass Air System which adversely affects the structural portions or the systems or equipment of the Building or is visible from the exterior of the Building.

ARTICLE 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, 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 (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. Tenant shall remove any such lien or encumbrance by bond or otherwise within five (5) days after notice by Landlord, and if Tenant shall fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof. The amount so paid shall be deemed Additional Rent under this Lease payable upon demand, without limitation as to other remedies available to Landlord under this Lease. 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. Notwithstanding anything to the contrary set forth in this Lease, Tenant may enter into certain

equipment financing and/or leasing arrangements with an equipment-seller or equipment-lessor to secure necessary furniture and equipment (collectively, the “Tenant’s Equipment”).

ARTICLE 10

INSURANCE

10.1 Indemnification and Waiver. Except to the extent caused by the negligence or willful misconduct of the “Landlord Parties” (as that term is defined below) , 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, 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 Land lord Parties from any and all loss, cost, damage, expense and liability (including without limitation court costs and reasonable attorneys’ fees) incurred in connection with or arising from: (a) any causes in or on the Premises; (b) the use or occupancy of the Premises by Tenant or any person claiming under Tenant; (c) any activity, work, or thing done, or permitted or suffered by Tenant in or about the Premises; (d) any acts, omission, or negligence of Tenant or any person claiming under Tenant, or the contractors, agents, employees, invitees, or visitors of Tenant or any such person; (e) any breach, violation, or non-performance by Tenant or any person claiming under Tenant or the employees, agents, contractors, invitees, or visitors of Tenant or any such person, of any term, covenant, or provision of this Lease or any law, ordinance, or governmental requirement of any kind; (f) any injury or damage to the person, property, or business of Tenant, its employees, agents, contractors, invitees, visitors, or any other person entering upon the Premises under the express or implied invitation of Tenant; or (g) the placement of any personal property or other items within the Premises; provided, however, that the terms of the foregoing indemnity shall not apply to the extent of the negligence or willful misconduct of Landlord or the 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 appraisers’, accountants’ and attorneys’ fees. Subject to Tenant’s indemnity and the waiver of subrogation provided below, 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, court costs and reasonable attorneys’ fees) arising from the negligence or willful misconduct of Landlord or the Landlord Parties in, on or about the Project either prior to or during the Lease Term, and/or as a result of Landlord’s breach of this Lease, except to the extent caused by the negligence or willful misconduct of Tenant or the Tenant Parties. Further, Tenant’s agreement to indemnify Landlord pursuant to this Section 10.1 is not intended and shall not relieve any insurance carrier of its obligations under policies required to be carried by Tenant pursuant to the provisions of this Lease, to the extent such policies cover the matters subject to Tenant’s 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. Notwithstanding anything to the contrary contained in this Lease, nothing in this Lease shall impose any obligations on Tenant or Landlord to be responsible or liable for, and each hereby releases the other from all liability for, consequential damages other than those consequential damages incurred by Landlord in connection with a holdover of the Premises by Tenant in accordance with the TCCS of Article 16 of this Lease.

10.2 Tenant’s Compliance With Landlord’s Fire and Casualty Insurance. Tenant shall, at Tenant’s expense, comply with Landlord’s insurance company requirements of which Tenant has received notice 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.

10.3 Tenant’s Insurance. Throughout the Lease Term, Tenant shall maintain the following coverages in the following amounts. The required evidence of coverage must be delivered to Landlord on or before the date required under Section 10.4(I) sub-sections (x) and (y), or Section 10.4(II) below (as applicable). Such policies shall be for a term of at least one (1) year, or the length of the remaining term of this Lease, whichever is less.

10.3.1 Commercial General Liability Insurance, including Broad Form contractual liability covering the insured against claims of bodily injury, personal injury and property damage (including loss of use thereof) based upon or arising out of Tenant’s operations, occupancy or maintenance of the Premises and all areas appurtenant thereto. Such insurance shall be written on an “occurrence” basis. Landlord and any other party the Landlord so specifies that has a material financial interest in the Project, including Landlord’s managing agent, ground lessor and/or lender, if any, shall be named as additional insureds as their interests may appear using Insurance Service Organization’s form CG2011 or a comparable form approved by Landlord. Tenant shall provide an endorsement or policy excerpt showing that Tenant’s coverage is primary and any insurance carried by Landlord shall be excess and non-contributing. The coverage shall also be extended to include damage caused by heat, smoke or fumes from a hostile fire. The policy shall not contain any intra-insured exclusions as between insured persons or organizations. This policy shall include coverage for all liabilities assumed under this Lease as an insured contract for the performance of all of Tenant’s indemnity obligations under this Lease. The limits of said insurance shall not, however, limit the liability of Tenant nor relieve Tenant of any obligation hereunder. Limits of liability insurance shall not be less than the following; provided, however, such limits may be achieved through the use of an Umbrella/Excess Policy:

Such insurance shall be written on a Special Form basis, for the full replacement cost value (subject to reasonable deductible amounts), 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 (a) all perils included in the CP 10 30 04 02 Coverage Special Form, (b) water damage from any cause whatsoever, including, but not limited to, backup or overflow from sprinkler leakage, bursting, leaking or stoppage of any pipes, explosion, and backup of sewers and drainage, and (c) terrorism (to the extent such terrorism insurance is available as a result of the Terrorism Risk Insurance Act of 2002 (Pub. L. l 07-297, 116 Stat. 2322), the Terrorism Risk Insurance Program Reauthorization Act of 2005 (Pub. l. 109-144), and the Terrorism Risk Insurance Program Reauthorization Act of 2007 (Pub. L. 110-160, 121 Stat. 183), any successor statute or regulation, or is otherwise available at commercially reasonable rates).

10.3.2.1 Adjacent Premises. Tenant shall pay for any increase in the premiums for the property insurance of the Project to the extent said increase is caused by Tenant’s acts, omissions, use or occupancy of the Premises for other than the Permitted Use (but which for purposes of this provision shall not apply to the extent resulting directly from the particular nature of Tenant’s tissue culture room and rodent vivarium uses).

10.3.2.2 Property Damage. Tenant shall use the proceeds from any such insurance for the replacement of personal property, trade fixtures and Alterations.

10.3.2.3 No representation of Adequate Coverage. Landlord makes no representation that the limits or forms of coverage of insurance specified herein are adequate to cover Tenant’s property, business operations or obligations under this Lease.

10.3.3 Property Insurance Subrogation. Landlord and Tenant intend that their respective property loss risks shall be borne by insurance carriers to the extent above provided (and, in the case of Tenant, by an insurance carrier satisfying the requirements of Section 10.4(i) below), and Landlord and Tenant hereby agree to look solely to, and seek recovery only from, their respective insurance carriers in the event of a property 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. Landlord and Tenant hereby represent and warrant that their respective “all risk” property insurance policies include a waiver of (i) subrogation by the insurers, and (ii) all rights based upon an assignment from its insured, against Landlord and/or any of the Landlord Parties or Tenant and/or any of the Tenant Parties (as the case may be) in connection with any property loss risk thereby insured against. Tenant will cause all other occupants of the Premises claiming by, under, or through Tenant to execute and deliver to Landlord a waiver of claims similar to the waiver in this Section 10.3.3 and to obtain such waiver of subrogation rights

endorsements. If either party hereto fails to maintain the waivers set forth in items (i) and (ii) above, the party not maintaining the requisite waivers shall indemnify, defend, protect, and hold harmless the other party for, from and against any and all claims, losses, costs, damages, expenses and liabilities (including, without limitation, court costs and reasonable attorneys’ fees) arising out of, resulting from, or relating to, such failure.

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) be issued by an insurance company having an AM Best rating of not less than A-X, or which is otherwise acceptable to Landlord and licensed to do business in the State of California, (ii) be in form and content reasonably acceptable to Landlord and complying with the requirements of Section 10.3 (including, Sections 10.3.1 through 10.3.6), (iii) Tenant shall not do or permit to be done anything which invalidates the required insurance policies, and (iv) 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, the identity of whom has been provided to Tenant in writing. Tenant shall deliver said policy or policies or certificates thereof and applicable endorsements which meet the requirements of this Article 10 to Landlord on or before (I) the earlier to occur of: (x) the Lease Commencement Date, and (y) the date Tenant and/or its employees, contractors and/or agents first enter the Premises for occupancy, construction of improvements, alterations, or any other move-in activities, and (II) five (5) business days after the renewal of such policies. In the event Tenant shall fail to procure such insurance, or to deliver such policies or certificates and applicable endorsements, Landlord may, at its option, after written notice to Tenant and Tenant’s failure to obtain such insurance within five (5) days thereafter, procure such policies for the account of Tenant and the sole benefit of Landlord, and the cost thereof shall be paid to Landlord after delivery to Tenant of bills therefor.

10.5 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; provided, however, that no such increase shall be requested or required by Landlord during the initial Lease Term.

10.6 Third-Party Contractors. Tenant shall obtain and deliver to Landlord, Third Party Contractor’s certificates of insurance and applicable endorsements at least seven (7) business days prior to the commencement of work in or about the Premises by any vendor or any other third-party contractor (collectively, a “Third Party Contractor”). All such insurance shall (a) name Landlord as an additional insured under such party’s liability policies as required by Section 10.3.1 above and this Section 10.6, (b) provide a waiver of subrogation in favor of Landlord under such Third Party Contractor’s commercial general liability insurance, (c) be primary and any insurance carried by Landlord shall be excess and non-contributing, and (d) comply with Landlord’s minimum insurance requirements.

10.7 Landlord’s Fire, Casualty, and Liability Insurance.

10.7.1 Landlord shall maintain Commercial General Liability Insurance with at least Five Million Dollars ($5,000,000) in coverage, with respect to the Building during the Lease Term covering claims for bodily injury, personal injury, and property damage in the Project Common Areas and with respect to Landlord’s activities in the Premises.

10.7.2 Landlord shall insure the Building and Landlord’s remaining interest in the Improvements and Alterations with a policy of Physical Damage Insurance including building ordinance coverage, written on a standard Causes of Loss—Special Form basis (against loss or damage due to fire and other casualties covered within the classification of fire and extended coverage, vandalism, and malicious mischief, sprinkler leakage, water damage and special extended coverage), covering the full replacement cost of the Base Building, Premises and other improvements (including coverages for enforcement of Applicable Laws requiring the upgrading, demolition, reconstruction and/or replacement of any portion of the Building as a result of a covered loss) without a deduction for depreciation.

10.7.3 Landlord shall maintain Boiler and Machinery/Equipment Breakdown Insurance covering the Building against risks commonly insured against by a Boiler and Machinery/Equipment Breakdown policy and such policy shall cover the full replacement costs, without deduction for depreciation.

10.7.4 The foregoing coverages shall contain commercially reasonable deductible amounts from such companies, and on such other terms and conditions, as Landlord may from time to time reasonably determine.

10.7.5 Additionally, at the option of Landlord, such insurance coverage may include the risk of (i) earthquake, (ii) flood damage and additional hazards, or (iii) a rental loss endorsement for a period of up to two (2) years.

10.7.6 Notwithstanding the foregoing provisions of this Section 10.7, the coverage and amounts of insurance carried by Landlord in connection with the Building shall, at a minimum, be comparable to the coverage and amounts of insurance which are carried by reasonably prudent landlords of Comparable Buildings. In addition, Landlord shall carry Worker’s Compensation and Employer’s Liability coverage as required by applicable law.

ARTICLE 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. Such restoration shall be to substantially the same condition of the Base Building and the Common Areas prior to the casualty, except for modifications required by zoning and building codes and other laws or by the holder of a mortgage on the Building or Project or any other modifications to the Common Areas deemed desirable by Landlord, which are consistent with the character of the Project, provided that access to the Premises and any common restrooms serving the Premises shall not be materially impaired. 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 10.3.2(ii) and (iii) of this Lease, and Landlord shall repair any injury or damage to the Improvements installed in the Premises and shall return such Improvements to their original condition; provided that if the cost of such repair by Landlord exceeds the amount of insurance proceeds received by Landlord from both Landlord’s insurance carrier and Tenant’s insurance carrier, as assigned by Tenant, the excess cost of such repairs shall be paid by Tenant to Landlord prior to Landlord’s commencement of repair of the damage. In the event that Landlord does not deliver the Landlord Repair Notice within sixty (60) days following the date the casualty becomes known to Landlord, then Tenant shall not assign its insurance proceeds as set forth hereinabove, and Tenant shall, at its sole cost and expense, repair any injury or damage to the Improvements installed in the Premises and shall return such Improvements to their original condition. Whether or not Landlord delivers a Landlord Repair Notice, prior to the commencement of construction, Tenant shall submit to Landlord, for Landlord’s review and approval, all plans, specifications and working drawings relating thereto, and Landlord shall select the contractors to perform such improvement work. 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 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, 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. In the event that Landlord shall not deliver the Landlord Repair Notice, Tenant’s right to rent abatement pursuant to the preceding sentence shall terminate as of the date Tenant should have completed repairs to the Premises assuming Tenant used reasonable due diligence in connection therewith.

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) the damage is not fully covered by Landlord’s insurance policies; (iv) Landlord decides to rebuild the Building or Common Areas so that they will be substantially different structurally or architecturally; (v) the damage occurs- during the last twelve (12) months of the Lease Term; or (vi) any owner of any other portion of the Project, other than Landlord, does not intend to repair the damage to such portion of the Project; 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 being commenced, 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 such 180-day period, 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 ten (10) 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 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. At any time, from time to time, after the date occurring sixty (60) days after the date of the damage, Tenant may request that Landlord inform Tenant of Landlord’s reasonable opinion of the date of completion of the repairs and Landlord shall respond to such request within five (5) business days. 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; and (c) as a result of the damage,

Tenant cannot reasonably conduct, and does not conduct, business from the Premises. In the event this Lease is terminated in accordance with the terms of this Section 11.2, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under items (ii) and (iii) of Section 10.3.2 of this Lease.

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.

ARTICLE 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.

ARTICLE 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 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. If more than ten percent (10%) of the rentable square feet of the Premises is taken, or if access to the Premises is substantially impaired, in each case for a period in excess of one hundred eighty (180) days, Tenant shall have the option to either (i) terminate this Lease effective as of the date possession is required to be surrendered to the authority, or (ii) continue this Lease in effect with a proportionate reduction in the Base Rent and Tenant’s Share of Direct Expenses. 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.

ARTICLE 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, including all existing operative

documents to be executed to evidence such Transfer or the agreements incidental or related to such Transfer, provided that Landlord shall have the right to require Tenant to utilize Landlord’s standard consent documents in connection with the documentation of Landlord’s consent to such Transfer, (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 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 and (v) an executed estoppel certificate from Tenant in the form attached hereto as Exhibit E. 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 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, in an amount not to exceed Two Thousand Five Hundred and No/100 Dollars ($2,500.00) in the aggregate, but such limitation of fees shall only apply to the extent such Transfer is in the ordinary course of business. Landlord and Tenant hereby agree that a proposed Transfer shall not be considered “in the ordinary course of business” if such Transfer involves the review of documentation by Landlord on more than two (2) occasions.

14.2 Landlord’s Consent. Landlord shall not unreasonably withhold its consent to any proposed Transfer (including without limitation any Transfer under Section 14.6 below) of the Subject Space to the Transferee on the terms specified in the Transfer Notice. 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 intends to use the Subject Space for purposes which are not permitted under this Lease;

14.2.3 The Transferee is either a governmental agency or instrumentality thereof;

14.2.4 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;

14.2.5 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;

14.2.6 The terms of the proposed Transfer will allow the Transferee to exercise a right of renewal, right of expansion, right of first offer, or other similar right held by Tenant (or will allow the Transferee to occupy space leased by Tenant pursuant to any such right); or

14.2.7 Either the proposed Transferee, or any person or entity which directly or indirectly, controls, is controlled by, or is under common control with, the proposed Transferee, occupies space in the Project at the time of the request for consent, or (ii) is negotiating with Landlord to lease space in the Project at such time, or (iii) has negotiated with Landlord during the six (6)-month period immediately preceding the Transfer Notice, and Landlord has reasonably comparable space in the Project then available to lease to such Transferee; or

14.2.8 The Transferee does not intend to occupy the entire Premises and conduct its business therefrom for a substantial portion of the term of the Transfer.

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 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 (i) such that Landlord would initially have been entitled to refuse its consent to such Transfer under this Section 14.2, or which would cause the proposed Transfer to be more favorable to the Transferee than the terms set forth in Tenant’s original Transfer Notice, 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 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 without any monetary damages, 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, after deducting the reasonable expenses incurred by Tenant for (i) any changes, alterations and improvements to the Premises in connection with the Transfer, (ii) any free base rent or other economic concessions reasonably provided to the Transferee, (iii) any brokerage commissions in connection with the Transfer, (iv) any attorneys’ fees incurred by Tenant in connection with the negotiation and documentation of the Transfer, (v) any lease takeover costs incurred by Tenant in connection with the Transfer, (vi) any costs of advertising the space which is the subject of the Transfer, and (vii) any review and processing fees paid to Landlord 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. In the calculations of the Rent (as it relates to the Transfer Premium calculated under this Section 14.3), the Rent paid during each annual period for the Subject Space shall be computed after adjusting such rent to the actual effective rent to be paid, taking into consideration any and all leasehold concessions granted in connection therewith, including, but not limited to, any rent credit and tenant improvement allowance. For purposes of calculating any such effective rent all such concessions shall be amortized on a straight-line basis over the relevant term.

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 of all or a portion of the Premises (or in the event of any other Transfer or Transfers entered into by Tenant as a subterfuge in order to avoid the terms of this Section 14.4), 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 for the term set forth in the Intention to Transfer Notice. Thereafter, Landlord shall have the option, by giving written notice to Tenant (the “Recapture Notice”) within twenty (20) days after receipt of any Intention to Transfer Notice, to recapture the Contemplated Transfer Space. However, if Landlord delivers a Recapture Notice to Tenant, Tenant may, within ten (10) days after Tenant’s receipt of such Recapture Notice, deliver written notice to Landlord rescinding the subject Intention to Transfer notice, in which case neither such Transfer or recapture shall be consummated and this Lease shall remain in full force and effect as to the corresponding Subject Space; provided, however, Tenant’s failure to timely rescind its Intention to Transfer Notice as set forth in this sentence shall be deemed to constitute Tenant’s election to allow the Recapture Notice to be effective. Any recapture shall cancel and terminate this Lease with respect to such Contemplated Transfer Space as of the Contemplated Effective Date (or at Landlord’s option, shall cause the Transfer to be made to Landlord or its agent, in which case the parties shall execute the Transfer documentation promptly thereafter). 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 twenty (20) 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 Article 14.4.

14.5 Effect of Transfer. If Landlord consents to a Transfer, (i) the TCCs 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 the 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 two percent (2%), Tenant shall pay Landlord’s costs of such audit.

14.6 Additional Transfers. Subject to the terms set forth in 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 more than fifty percent (50%) or more of the partners, or transfer of more than 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 ( i.e., whose stock is not publicly held and not traded through an exchange or over the counter), the dissolution, merger, consolidation or other reorganization of Tenant or (B) the sale or other transfer of an aggregate of more than fifty percent (50%) or more of the voting shares of Tenant within a twelve (12)-month period (but excluding transfers (a) to immediate family members by reason of gift or death, or (b) by any of Tenant’s investors to any such investor’s limited partners and/or members), or (C) the sale, mortgage, hypothecation or pledge of an aggregate of more than fifty percent (50%) or more of the value of the unencumbered assets of Tenant within a twelve (12)-month period; provided, however, the parties hereby acknowledge that transactions involving Tenant’s stock or assets that fall below the specified thresholds described in this sentence above shall not require Landlord’s consent. Notwithstanding the foregoing, the raising of capital by Tenant in connection with a sale, issuance or other offering of stock or ownership interests in Tenant (each, together with any related transactions, a “Capital Raising Event”) shall not be deemed a Transfer nor require Landlord’s consent hereunder; provided, however, (1) any such Capital Raising Event shall be for the bona fide purpose of raising capital in Tenant (as opposed to being for the purpose of a total or partial liquidation of an existing shareholder’s interest in Tenant) and is not otherwise a subterfuge by Tenant to avoid its obligations under this Lease, and (2) Tenant shall continue to conduct its business operations in the Premises in accordance with the Permitted Use.

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 the applicable notice and cure period 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.

14.8 Non-Transfers. Notwithstanding anything to the contrary contained in this Article 14, (i) a Transfer 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), (ii) a Transfer to an entity which acquires all or substantially all of the assets or interests (partnership, stock or other) of Tenant, or (iii) a Transfer to an entity which is the resulting entity of a merger, consolidation, public offering, reorganization or dissolution of Tenant, or which becomes the parent or successor of Tenant by reason of merger, consolidation, public offering, reorganization, dissolution, or sale of stock, membership or partnership interests or assets, shall not be deemed a Transfer under this Article 14, provided that Tenant notifies Landlord of any such assignment or sublease and promptly supplies Landlord with any documents or information requested by Landlord regarding such assignment or sublease or such affiliate, and further provided that such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease or otherwise effectuate any “release” by Tenant of such obligations and such Permitted Transferee shall thereafter become liable under this Lease, on a joint and several basis, with Tenant. The assignee under an assignment specified in items (i), (ii) or (iii) above shall be referred to as a “Permitted Transferee.” “Control,” as used in this Section 14.8, shall mean the ownership, directly or indirectly, of more than fifty percent (50%) of the voting securities of, or possession of the right to vote, in the ordinary direction of its affairs, of more than fifty percent (50%) of the voting interest in, any person or entity.

14.9 Occupancy by Others. Notwithstanding any contrary provision of this Article 14, Tenant shall have the right (without the payment of a Transfer Premium, without being subject to Section 14.4, and without the receipt of Landlord’s consent, but only following prior written notice to Landlord), to permit the occupancy (which shall otherwise be deemed a Transfer hereunder) of up to a cumulative total of twenty-five percent (25%) of the rentable square footage of the Premises, in the aggregate, to any individual(s) with an ongoing, business substantially similar to the Permitted Use (“Tenant’s Occupants”) on and subject to the following conditions: (i) such individuals or entities shall not be permitted to occupy a separately

demised portion of the Premises which contains an entrance to such portion of the Premises other than the primary entrance to the Premises; (ii) all such individuals or entities shall be of a character and reputation consistent with the first-class quality of the Building and the Project; and (iii) such occupancy shall not be a subterfuge by Tenant to avoid its obligations under this Lease or the restrictions on Transfers pursuant to this Article L 4. Tenant shall promptly supply Landlord with any documents or information reasonably requested by Landlord regarding any such individuals or entities. Notwithstanding the foregoing, no such occupancy shall relieve Tenant from any liability under this Lease.

ARTICLE 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 and repairs which are specifically made the responsibility of Landlord hereunder 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, business and trade fixtures, 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.

ARTICLE 16

HOLDING OVER

If Tenant holds over after the expiration of the Lease Term or earlier termination thereof, with or without 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, and in such case Rent shall be payable at a monthly rate equal to the product of (i) the Rent

applicable during the last rental period of the Lease Term under this Lease, and (ii) a percentage equal to one hundred fifty percent (150%). Such month-to-month tenancy 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; provided, however, to the extent Landlord affirmatively consents to Tenant’s holding over in the Premises, then in no event shall Tenant be liable to Landlord for, or otherwise be required to indemnify Landlord with respect to, any consequential damages in connection therewith. If Tenant fails to surrender the Premises upon the termination or expiration of this Lease without Landlord’s affirmative consent, 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; provided, however, that in no event shall Tenant be liable for consequential damages attributable to the first thirty (30) days of any holding over by Tenant. In the event of any potential or actual holding over of the Premises by Tenant, Tenant may elect to send a written notice to Landlord (specifically referencing this Article 16) requesting an update as to whether Landlord has entered into a third-party lease for the Premises following the expiration or earlier termination of this Lease, and Landlord shall, within ten (10) business days of its receipt of such notice from Tenant, notify Tenant whether or not Landlord has entered into a third-party lease as of the date of such notice for the Premises following the expiration or earlier termination of this Lease; provided, however, in no event shall any such notice by Tenant to Landlord, or any subsequent notice from Landlord to Tenant (or any failure by Landlord to provide such notice) be deemed a waiver of any of Tenant’s obligations or liabilities under this Article 16.

ARTICLE 17

ESTOPPEL CERTIFICATES

Within ten (10) 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 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. Tenant shall execute and deliver whatever other commercially reasonable instruments may be reasonably required for such purposes. At any time during the Lease Term, Landlord may require Tenant to provide Landlord with a current financial statement and financial statements of the two (2) years prior to the current financial statement year. 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 or other instruments 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.

ARTICLE 18

SUBORDINATION

Landlord covenants that there is no existing mortgage, deed of trust, ground lease or other encumbrance encumbering the Project or any portion thereof as of the Effective Date. This Lease shall be subject and subordinate to all future ground or underlying leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances 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, that in consideration of and a condition precedent to Tenant’s agreement to subordinate this Lease, shall be the receipt by Tenant of a subordination non-disturbance and attornment agreement in a commercially reasonable form, which requires such Superior Holder to accept this lease, and not to disturb tenant’s possession, so long as an event of default has not occurred and be continuing (a “SNDA”) executed by Landlord and the appropriate Superior Holder. Subject to Tenant’s receipt of an SNDA, Tenant covenants and agrees that 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 TCCs of this Lease to be observed and performed by Tenant. Landlord’s interest herein may be assigned as security at any time to any lienholder. Tenant shall, within five (5) days of request by Landlord, execute such further 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.

ARTICLE 19

DEFAULTS; REMEDIES

19.1 Events of Default. The occurrence of any of the following shall constitute a default of this Lease by Tenant:

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 unless such failure is cured within five (5) business days after notice; or

19.1.2 Except where a specific time period is otherwise set forth for Tenant’s performance in this Lease, in which event the failure to perform by Tenant within such time period shall be a default by Tenant under this Section 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, but in no event exceeding a period of time in excess of ninety (90) days after written notice thereof from Landlord to Tenant; or

19.1.3 To the extent permitted by law, (i) Tenant or any guarantor of this Lease being placed into receivership or conservatorship, or becoming subject to similar proceedings under Federal or State law, or (ii) a general assignment by Tenant or any guarantor of this Lease for the benefit of creditors, or (iii) the taking of any corporate action in furtherance of bankruptcy or dissolution whether or not there exists any proceeding under an insolvency or bankruptcy law, or (iv) the filing by or against Tenant or any guarantor of any proceeding under an insolvency or bankruptcy law, unless in the case of such a proceeding filed against Tenant or any guarantor the same is dismissed within sixty (60) days, or (v) the appointment of a trustee or receiver to take possession of all or substantially all of the assets of Tenant or any guarantor, unless possession is restored to Tenant or such guarantor within thirty (30) days, or (vi) any execution or other judicially authorized seizure of all or substantially all of Tenant’s assets located upon the Premises or of Tenant’s interest in this Lease, unless such seizure is- discharged within thirty (30) days; or

19.1.4 Abandonment or vacation pursuant to the terms of California Civil Code Section 1951.3 of all or a substantial portion of the Premises by Tenant; or

19.1.5 The failure by Tenant to observe or perform according to the provisions of Articles 17 or 18 of this Lease where such failure continues for more than five (5) business days after notice from Landlord; or

19.1.6 The failure by Tenant to observe or perform according to the provisions of Articles 5 or 14 of this Lease where such failure continues for more than ten (10) business days after notice from Landlord; or

19.1.7 Tenant’s failure to occupy the Premises within one hundred twenty (120) days after the Lease Commencement Date.

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, 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 (except as otherwise expressly set forth in this Lease).

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 for damages therefor; and Landlord may recover from Tenant the following:

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

(b) 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

(c) 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

(d) Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of 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

(e) At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by 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(a) and (b), above, the “worth at the time of award” shall be computed by allowing interest at the Interest Rate. As used in Section 19.2.1(c), 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.

19.4 Form of Payment After Default. Following the occurrence of the second (2^nd) event of economic default by Tenant (beyond all applicable notice and cure periods) occurring within any twelve (12) month period, Landlord shall have the right to require that any or all subsequent amounts paid by Tenant to Landlord hereunder, whether to cure the default in question or otherwise, be paid in the form of cash, money order, cashier’s or certified check drawn on an institution acceptable to Landlord, or by other means approved by Landlord, notwithstanding any prior practice of accepting payments in any different form.

19.5 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.

19.6 Landlord Default. Notwithstanding anything to the contrary set forth in this Lease, Landlord shall be in default in the performance of any obligation required to be performed by Landlord pursuant to this Lease if Landlord fails to perform such obligation within 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 pursues 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. Any award from a court or arbitrator in favor of Tenant requiring payment by Landlord which is not paid by Landlord within the time period directed by such award, may be offset by Tenant from Rent next due and payable under this Lease; provided, however, Tenant may not deduct the amount of the award against more than fifty percent (50%)

of Base Rent next due and owing (until such time as the entire amount of such judgment is deducted) to the extent following a foreclosure or a deed-in-lieu of foreclosure.

ARTICLE 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 TCCs, 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 TCCs, 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.

ARTICLE 21

SECURITY DEPOSIT

Concurrent 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 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, 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 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 (i) any and all sums expressly identified in this Article 21, above, and (ii) 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 this Lease pursuant to Section 1951.2 of the California Civil Code.

ARTICLE 22

LETTER OF CREDIT

22.1 Delivery of Letter of Credit. Tenant shall deliver to Landlord, within forty-five (45) days following Tenant’s execution of this Lease, an unconditional, clean, irrevocable letter of credit (the “L-C”) in the amount set forth in Section 22.3 below (the “L-C Amount”), which L-C shall be issued by a money-center, solvent and nationally recognized bank (a bank which accepts deposits, maintains accounts, has a local San Diego office which will negotiate a letter of credit, and whose deposits are insured by the FDIC) reasonably acceptable to Landlord, and Landlord hereby pre-approves UBS Bank USA (such approved, issuing bank being referred to herein as the “Bank”), which Bank must have a short term Fitch Rating which is not less than “F l “, and a long term Fitch Rating which is not less than “A”(or in the event such Fitch Ratings are no longer available, a comparable rating from Standard and Poor’ s Professional Rating Service or Moody’s Professional Rating Service) (collectively, the “Bank’s Credit Rating Threshold”), and which L-C shall be substantially in the form of Exhibit G, attached hereto. Tenant shall pay all expenses, points and/or fees incurred by Tenant in obtaining the L-C. The L-C shall (i) be “callable” at sight, irrevocable and unconditional, (ii) be maintained in effect, whether through renewal or extension, for the period commencing on the date of issuance of such L-C and continuing until the date (the “L-C Expiration Date”) that is no less than one hundred twenty (120) days after the expiration of the Lease Term, as the same may be extended, and Tenant shall deliver a new L-C or certificate of renewal or extension to Landlord at least thirty (30) days prior to the expiration of the L-C then held by Landlord, without any action whatsoever on the part of Landlord, (iii) be fully assignable by Landlord, its successors and assigns, (iv) permit partial draws and multiple presentations and drawings, and (v) be otherwise subject to the Uniform Customs and Practices for Documentary Credits (1993-Rev), International Chamber of Commerce Publication #500, or the International Standby Practices- ISP 98, International Chamber of Commerce Publication #590. Landlord, or its then managing agent, shall have the right to draw down an amount up to the face amount of the L-C if any of the following shall have occurred or be applicable: (A) such amount is due to Landlord under the terms and conditions of this Lease, or (B) Tenant has filed a voluntary petition under the U. S. Bankruptcy Code or any state bankruptcy code (collectively, “Bankruptcy Code”), or (C) an involuntary petition has been filed against Tenant under the Bankruptcy Code, or (D) the Bank has notified Landlord that the L-C will not be renewed or extended through the L-C Expiration Date, or (E) Tenant is placed into receivership or conservatorship, or becomes subject to similar proceedings under Federal or State law, or (F) Tenant executes an assignment for the benefit of creditors, or (G) if (I) any of the Bank’s Fitch Ratings (or other comparable ratings to the extent the Fitch Ratings are no longer available) have been reduced below the Bank’s Credit Rating Threshold, or (2) there is otherwise a material adverse change in the financial condition of the Bank, and Tenant has failed to provide Landlord with a replacement letter of credit, conforming in all respects to the requirements of this Article 22 (including, but not limited to, the requirements placed on the issuing Bank more particularly set forth in this Section 22.1 above), in the amount of the applicable L-C Amount, within ten (IO) days following Landlord’s written demand therefor (with no other notice or cure or grace period being applicable thereto, notwithstanding anything in this Lease to the contrary) (each of the foregoing being an “L-C Draw Event”). The L-C shall be honored by the Bank regardless of whether Tenant disputes Landlord’s right to draw upon the L-C. In addition, in the event the Bank is placed into receivership or conservatorship by the

Federal Deposit Insurance Corporation or any successor or similar entity, then, effective as of the date such receivership or conservatorship occurs, said L-C shall be deemed to fail to meet the requirements of this Article 22, and, within ten (10) days following Landlord’s notice to Tenant of such receivership or conservatorship (the “L-C FDIC Replacement Notice”), Tenant shall replace such L-C with a substitute letter of credit from a different issuer (which issuer shall meet or exceed the Bank’s Credit Rating Threshold and shall otherwise be acceptable to Landlord in its reasonable discretion) and that complies in all respects with the requirements of this Article 22. If Tenant fails to replace such L-C with such conforming, substitute letter of credit pursuant to the terms and conditions of this Section 22.1, then, notwithstanding anything in this Lease to the contrary, Landlord shall have the right to declare Tenant in default of this Lease for which there shall be no notice or grace or cure periods being applicable thereto (other than the aforesaid ten (10) day period). Tenant shall be responsible for the payment of any and all costs incurred with the review of any replacement L-C (including without limitation Landlord’s reasonable attorneys’ fees), which replacement is required pursuant to this Section or is otherwise requested by Tenant.

22.2 Application of L-C. Tenant hereby acknowledges and agrees that Landlord is entering into this Lease in material reliance upon the ability of Landlord to draw upon the L-C upon the occurrence of any L-C Draw Event. In the event of any L-C Draw Event, Landlord may, but without obligation to do so, and without notice to Tenant, draw upon the L-C, in part or in whole, to cure any such L-C Draw Event and/or to compensate Landlord for any and all damages of any kind or nature sustained or which Landlord reasonably estimates that it will sustain resulting from Tenant’s breach or default of the Lease or other L-C Draw Event and/or to compensate Landlord for any and all damages arising out of, or incurred in connection with, the termination of this Lease, including, without limitation, those specifically identified in Section 1951.2 of the California Civil Code. The use, application or retention of the L-C, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by any applicable law, it being intended that Landlord shall not first be required to proceed against the L-C, and such L-C shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled. No condition or term of this Lease shall be deemed to render the L-C conditional to justify the issuer of the L-C in failing to honor a drawing upon such L-C in a timely manner. Tenant agrees and acknowledges that the L-C constitutes a separate and independent contract between Landlord and the Bank, Tenant is not a third party beneficiary of such contract, (iii) Tenant has no property interest whatsoever in the L-C or the proceeds thereof, and (iv) in the event Tenant becomes a debtor under any chapter of the Bankruptcy Code, Tenant is placed into receivership or conservatorship, and/or there is an event of a receivership, conservatorship or a bankruptcy filing by, or on behalf of, Tenant, neither Tenant, any trustee, nor Tenant’s bankruptcy estate shall have any right to restrict or limit Landlord’s claim and/or rights to the L-C and/or the proceeds thereof by application of Section 502(b)(6) of the U. S. Bankruptcy Code or otherwise.

22.3 L-C Amount; Maintenance of L-C by Tenant; Liquidated Damages.

22.3.1 L-C Amount. The L-C Amount shall initially be equal to One Hundred Sixty Thousand and 00/100 Dollars ($160,000.00).

22.3.2 Reduction of L-C Amount. To the extent that Tenant is not in default under this Lease (beyond the applicable notice and cure period set forth in this Lease), the L-C Amount shall be reduced as follows:


Date of Reduction	L-C Amount
September 1, 2012	$	135,000.00
September 1, 2013	$	110,000.00
September 1, 2014	$	85,000.00
September 1, 2015	$	60,000.00

Notwithstanding anything to the contrary set forth in this Section 22.3.2, in no event shall the L-C Amount as set forth above decrease during any period in which Tenant is in default under this Lease (beyond any applicable notice and cure periods), but such decrease shall take place retroactively after such default is cured, provided that no such decrease shall thereafter take effect in the event this Lease is terminated early due to such default by Tenant.

22.3.3 In General. If, as a result of any drawing by Landlord of all or any portion of the L-C, the amount of the L-C shall be less than the L-C Amount, Tenant shall, within ten (10) days thereafter, provide Landlord with additional letter(s) of credit in an amount equal to the deficiency, and any such additional letter(s) of credit shall comply with all of the provisions of this Article 22, and if Tenant fails to comply with the foregoing, the same shall be subject to the terms of Section 22.3.3 below. Tenant further covenants and warrants that it will neither assign nor encumber the L-C or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance. Without limiting the generality of the foregoing, if the L-C expires earlier than the L-C Expiration Date, Landlord will accept a renewal thereof (such renewal letter of credit to be in effect and delivered to Landlord, as applicable, not later than thirty (30) days prior to the expiration of the L-C), which shall be irrevocable and automatically renewable as above provided through the L-C Expiration Date upon the same terms as the expiring L-C or such other terms as may be acceptable to Landlord in its sole discretion. If Tenant exercises its option to extend the Lease Term pursuant to Section 2.3 of this Lease then, not later than one hundred twenty (120) days prior to the commencement of the applicable Option Term, Tenant shall deliver to Landlord a new L-C or certificate of renewal or extension evidencing the L-C Expiration Date as one hundred twenty (120) days after the expiration of the Option Term. However, if the L-C is not timely renewed, or if Tenant fails to maintain the L-C in the amount and in accordance with the terms set forth in this Article 22, Landlord shall have the right to either (x) present the L-C to the Bank in accordance with the terms of this Article 22, and the proceeds of the L-C may be applied by Landlord against any Rent payable by Tenant under this Lease that is not paid when due and/or to pay for all losses and damages that Landlord has suffered or that Landlord reasonably estimates that it will suffer as a result of any breach or default by Tenant under this Lease, or (y) pursue its remedy under Section 22.3.3 below. In the event Landlord elects to exercise its rights under the foregoing item (x), (I) any unused proceeds shall constitute the property of Landlord (and not Tenant’s property or, in the event of a

receivership, conservatorship, or a bankruptcy filing by Tenant, property of such receivership, conservatorship or Tenant’s bankruptcy estate) and need not be segregated from Landlord’s other assets, and (II) Landlord agrees to pay to Tenant within thirty (30) days after the L-C Expiration Date the amount of any proceeds of the L-C received by Landlord and not applied against any Rent payable by Tenant under this Lease that was not paid when due or used to pay for any losses and/or damages suffered by Landlord (or reasonably estimated by Landlord that it will suffer) as a result of any breach or default by Tenant under this Lease; provided, however, that if prior to the L-C Expiration Date a voluntary petition is filed by Tenant, or an involuntary petition is filed against Tenant by any of Tenant’s creditors, under the Bankruptcy Code, then Landlord shall not be obligated to make such payment in the amount of the unused L-C proceeds until either all preference issues relating to payments under this Lease have been resolved in such bankruptcy or reorganization case or such bankruptcy or reorganization case has been dismissed.

22.3.4 FAILURE TO MAINTAIN; REPLACE AND/OR REINSTATE L-C; LIQUIDATED DAMAGES. IN THE EVENT THAT TENANT FAILS, WITHIN (I) THAT PERIOD SET FORTH IN SECTION 22.3.2 ABOVE, OR (II) THAT PERIOD SET FORTH IN THE L-C FDIC REPLACEMENT NOTICE, TO PROVIDE LANDLORD WITH ADDITIONAL L-C(S) IN AN AMOUNT EQUAL TO THE DEFICIENCY OR A REPLACEMENT L-C (AS APPLICABLE), THEN TENANT’S MONTHLY INSTALLMENT OF BASE RENT SHALL BE INCREASED TO ONE HUNDRED TEN PERCENT (110%) OF ITS THEN EXISTING LEVEL DURING THE PERIOD COMMENCING ON THE DATE WHICH IS THE LAST DAY OF THE PERIOD IDENTIFIED IN SECTION 22.3.2 OR THE L-C FDIC REPLACEMENT NOTICE (AS APPLICABLE), AND ENDING ON THE EARLIER TO OCCUR OF (X) THE DATE TENANT PROVIDES LANDLORD WITH ADDITIONAL L-C(S) IN AN AMOUNT EQUAL TO THE DEFICIENCY AS CONTEMPLATED BY THE TERMS OF SECTION 22.3.2 ABOVE, OR THE L-C FDIC REPLACEMENT NOTICE (AS APPLICABLE), OR (Y) THE DATE WHICH IS NINETY (90) DAYS AFTER THE LAST DAY OF THE PERIOD IDENTIFIED IN SECTION 22.3.2 OR THE L-C FDIC REPLACEMENT NOTICE (AS APPLICABLE). IN THE EVENT THAT TENANT FAILS, DURING SUCH NINETY (90) DAY PERIOD FOLLOWING THE LAST DAY OF THE PERIOD IDENTIFIED IN SECTION 22.3.2 OR THE L-C FDIC REPLACEMENT NOTICE (AS APPLICABLE), TO PROVIDE LANDLORD WITH ADDITIONAL L-C(S) IN AN AMOUNT EQUAL TO THE DEFICIENCY OR A REPLACEMENT L-C (AS APPLICABLE), THEN TENANT’S MONTHLY INSTALLMENT OF BASE RENT SHALL BE INCREASED TO ONE HUNDRED TWENTY PERCENT (120%) OF ITS THEN EXISTING LEVEL DURING THE PERIOD COMMENCING ON THE DATE WHICH IS NINETY (90) DAYS AFTER THE LAST DAY OF THE PERIOD IDENTIFIED IN SECTION 22.3.2 OR THE L-C FDIC REPLACEMENT NOTICE (AS APPLICABLE) AND ENDING ON THE DATE SUCH ADDITIONAL L-C(S) ARE ISSUED IN AN AMOUNT EQUAL TO THE DEFICIENCY OR SUCH A REPLACEMENT L-C IS ISSUED (AS APPLICABLE) PURSUANT TO THE TERMS OF SECTION 22.3.2 OR THE L-C FDIC REPLACEMENT NOTICE (AS APPLICABLE). THE PARTIES AGREE THAT IT WOULD BE IMPRACTICABLE AND EXTREMELY DIFFICULT TO ASCERTAIN THE ACTUAL DAMAGES SUFFERED BY LANDLORD AS A RESULT OF TENANT’S FAILURE TO TIMELY PROVIDE LANDLORD WITH ADDITIONAL L-C(S) IN AN AMOUNT EQUAL TO THE DEFICIENCY AS REQUIRED IN SECTION 22.3.2, OR A REPLACEMENT L-C AS CONTEMPLATED BY THE L-C FDIC REPLACEMENT NOTICE

(AS APPLICABLE), AND THAT UNDER THE CIRCUMSTANCES EXISTING AS OF THE EFFECTIVE DATE, THE LIQUIDATED DAMAGES PROVIDED FOR IN THIS SECTION 22.3.3 REPRESENT A REASONABLE ESTIMATE OF THE DAMAGES WHICH LANDLORD WILL INCUR AS A RESULT OF SUCH FAILURE, PROVIDED, HOWEVER, THAT THIS PROVISION SHALL NOT WAIVE OR AFFECT LANDLORD’S RIGHTS AND TENANT’S INDEMNITY OBLIGATIONS UNDER OTHER SECTIONS OF THIS LEASE (EXCEPT THAT THE PARTIES SPECIFICALLY AGREE THAT THE FOREGOING PROVISION WAS AGREED TO IN LIEU OF MAKING FAILURE TO PROVIDE LANDLORD WITH ADDITIONAL L-C(S) IN AN AMOUNT EQUAL TO THE DEFICIENCY OR A REPLACEMENT L-C (AS APPLICABLE) A DEFAULT UNDER THIS LEASE). THE PARTIES ACKNOWLEDGE THAT THE PAYMENT OF SUCH LIQUIDATED DAMAGES IS NOT INTENDED AS A FORFEITURE OR PENALTY WITHIN THE MEANING OF CALIFORNIA CIVIL CODE SECTION 3275 OR 3369, BUT IS INTENDED TO CONSTITUTE LIQUIDATED DAMAGES TO LANDLORD PURSUANT TO CALIFORNIA CIVIL CODE SECTION 1671. THE PARTIES HAVE SET FORTH THEIR INITIALS BELOW TO INDICATE THEIR AGREEMENT WITH THE LIQUIDATED DAMAGES PROVISION CONTAINED IN THIS SECTION 22.3.

		LANDLORD’S INITIALS		TENANT’S INITIALS

22.4 Transfer and Encumbrance. The L-C shall also provide that Landlord may, at any time and without notice to Tenant and without first obtaining Tenant’s consent thereto, transfer (one or more times) all of its interest in and to the L-C to another party, in connection with the assignment by Landlord of its rights and interests in and to this Lease. In the event of a transfer of Landlord’s interest in under this Lease, Landlord shall transfer the L-C to the transferee and thereupon Landlord shall, without any further agreement between the parties, be released by Tenant from all liability therefor, and it is agreed that the provisions hereof shall apply to every transfer or assignment of the whole of said L-C to a new landlord. In connection with any such transfer of the L-C by Landlord, Tenant shall execute and submit to the Bank such applications, documents and instruments as may be necessary to effectuate such transfer; provided, however, with regard to the cost of any particular transfer, Landlord shall be responsible for, and shall pay, the first $1000 of the Bank’s transfer and processing fees in connection therewith, with Tenant being responsible for any excess.

22.5 L-C Not a Security Deposit. Landlord and Tenant (1) acknowledge and agree that in no event or circumstance shall the L-C or any renewal thereof or substitute therefor or any proceeds thereof be deemed to be or treated as a “security deposit” under any law applicable to security deposits in the commercial context, including, but not limited to, Section 1950.7 of the California Civil Code, as such Section now exists or as it may be hereafter amended or succeeded (the “Security Deposit Laws”), (2) acknowledge and agree that the L-C (including any renewal thereof or substitute therefor or any proceeds thereof) is not intended to serve as a security deposit, and the Security Deposit Laws shall have no applicability or relevancy thereto, and (3) waive any and all rights, duties and obligations that any such party may now, or in the future will, have relating to or arising from the Security Deposit Laws. Tenant hereby irrevocably waives and relinquishes the provisions of Section 1950.7 of the California Civil Code and any successor statue, and all other provisions of law, now or hereafter in effect, which

(x) establish the time frame by which a landlord must refund a security deposit under a lease, and/or (y) provide 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 caused by a tenant or to clean the premises, it being agreed that Landlord may, in addition, claim those sums specified in this Article 22 and/or those sums reasonably necessary to (a) compensate Landlord for any loss or damage caused by Tenant’s breach of this Lease, including any damages Landlord suffers following termination of this Lease, and/or (b) compensate Landlord for any and all damages arising out of, or incurred in connection with, the termination of this Lease, including, without limitation, those specifically identified in Section 1951.2 of the California Civil Code.

22.6 Non-Interference By Tenant. Tenant agrees not to interfere in any way with any payment to Landlord of the proceeds of the L-C, either prior to or following a “draw” by Landlord of all or any portion of the L-C, regardless of whether any dispute exists between Tenant and Landlord as to Landlord’s right to draw down all or any portion of the L-C. No condition or term of this Lease shall be deemed to render the L-C conditional and thereby afford the Bank a justification for failing to honor a drawing upon such L-C in a timely manner. Tenant shall not request or instruct the Bank of any L-C to refrain from paying sight draft(s) drawn under such L-C.

22.7 Waiver of Certain Relief. Tenant unconditionally and irrevocably waives (and as an independent covenant hereunder, covenants not to assert) any right to claim or obtain any of the following relief in connection with the L-C:

22.7.1 A temporary restraining order, temporary injunction, permanent injunction, or other order that would prevent, restrain or restrict the presentment of sight drafts drawn under any L-C or the Bank’s honoring or payment of sight draft(s); or

22.7.2 Any attachment, garnishment, or levy in any manner upon either the proceeds of any L-C or the obligations of the Bank (either before or after the presentment to the Bank of sight drafts drawn under such L-C) based on any theory whatever.

22.8 Remedy for Improper Drafts. Tenant’s sole remedy in connection with the improper presentment or payment of sight drafts drawn under any L-C shall be the right to obtain from Landlord a refund of the amount of any sight draft(s) that were improperly presented or the proceeds of which were misapplied, together with interest at the Interest Rate and reasonable actual out-of-pocket attorneys’ fees, provided that at the time of such refund, Tenant increases the amount of such L-C to the amount (if any) then required under the applicable provisions of this Lease. Tenant acknowledges that the presentment of sight drafts drawn under any L-C, or the Bank’s payment of sight drafts drawn under such L-C, could not under any circumstances cause Tenant injury that could not be remedied by an award of money damages, and that the recovery of money damages would be an adequate remedy therefor. In the event Tenant shall be entitled to a refund as aforesaid and Landlord shall fail to make such payment within ten (10) business days after demand, Tenant shall have the right to deduct the amount thereof together with interest thereon at the Interest Rate from the next installment(s) of Base Rent.

ARTICLE 23

SIGNS

23.1 Full Floors. Subject to Landlord’s prior written approval, in its sole discretion, and provided all signs are compatible with the quality, design and style of the Project’s sign criteria then established by Landlord (the “Project Sign Criteria”), and provided all signs are in keeping with the quality, design and style of the Building and Project, Tenant and any of Tenant’s Permitted Transferees or Tenant’s Occupants, at its sole cost and expense, may install identification signage anywhere on the floor in which the Premises is located including in the elevator lobby of the floor where the Premises is located, provided that such signs must not be visible from the exterior of the Building. In addition, Tenant shall have the right, at Tenant’s sole cost and expense, to have its name listed by Landlord on one (1) line in the directory to be located in a mutually and reasonably determined location in the lobby of the Building.

23.2 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. Except as otherwise expressly provided in Sections 23.3 and 23.4, below, Tenant may not install any signs on the exterior or roof of the Project or the Common Areas. Any signs, window coverings, or blinds (even if the same are located behind the Landlord-approved window coverings for the Building), or other items visible from the exterior of the Premises or Building, shall be subject to the prior approval of Landlord, in its sole discretion.

23.3 Building Top Sign. Notwithstanding any provision to the contrary contained in this Article 23, the Original Tenant and any of its Permitted Transferees shall have the right, but not the obligation, at the sole cost and expense of Tenant, to install one (1) non-exclusive Building-top sign on the roof of the Building in one ( l ) location to be mutually and reasonably agreed upon by Landlord and Tenant (the “Building-Top Sign”), which Building-Top Sign may, subject to the terms set forth in Section 23.6, below, contain Tenant’s name and/or Tenant’s logo. Such Building-Top Sign shall conform to all zoning and CC&Rs, and shall be subject to the Project Sign Criteria and Landlord’s reasonable review and approval. All costs associated with the Building-Top Sign, including, without limitation, the costs to purchase, install, maintain, and remove it, shall be borne exclusively by Tenant.

23.4 Monument Signage. Original Tenant and any of its Permitted Transferees shall have the non-exclusive right, but not the obligation, to have its name and/or logo as determined by Tenant placed on portion of any multi-tenant monument sign serving the Building (which portion shall be determined based on the rentable square footage then leased by Tenant), and such signage shall be compatible with the quality, design and style of the Project’s Sign Criteria; provided, however, in no event shall Tenant’s signage include an “Objectionable Name,” as that term is defined in Section 23.8, of this Lease. Landlord shall have the right to (i) position or prioritize Tenant’s name in any position on such monument signage as it shall determine in its sole discretion, from time to time, (ii) design and organize such monument signage (and the materials, design, script size, type face, colors and all other characteristics thereof) in such manner as it shall determine in its sole discretion, (iii) place such other names, business names, trade names or affiliate names representing such other tenants as it shall determine in its sole

discretion, (iv) make such modifications to such monument signage as it shall desire from time to time so long as such changes do not materially adversely affect Tenant’s monument signage rights under this Section 23.4, and (v) place thereon the name of (and/or other identifying information for) the Building and/or Project as Landlord shall determine in its sole discretion.

23.5 Rights Personal. The rights granted under Sections 23.3 and 23.4 are personal to the Original Tenant and its Permitted Transferees, and shall not be transferable in any other respect whatsoever. If (i) the Lease shall be assigned to any party other than Permitted Transferee, (ii) there is an event of default (beyond the applicable notice and cure periods) exists under this Lease, or (iii) the Original Tenant or its Permitted Transferee (together with any Tenant’s Occupants) occupies less than the entire Premises (except for time periods during repairs, remodeling or similar circumstances), Landlord shall have the right to cancel Tenant’s rights under this Section 23.5 and to require Tenant to remove at Tenant’s sole cost and expense Tenant’s name from such monument signage within fifteen ( 15) days after delivery of Landlord ‘s written notice to do so.

23.6 Specifications and Permits. The graphics, materials, color, design, lettering, size and specifications of Tenant’s name on such monument signage and Building-Top Sign (collectively, the “Sign Specifications”) shall be (i) subject to the prior written consent of Landlord, including, without limitation, as to the design, materials, color, size and all other aesthetic factors of such signage and which consent thereto shall be in Landlord’s sole discretion; (ii) consistent with the size and quality of comparable signage on comparable institutionally owned first-class office buildings in the local market, (iii) in compliance with all Laws, (iv) subject to receipt by Tenant of all required governmental permits and approvals therefore, and (v) consistent with the Project Sign Criteria and the overall character of the Building’s/Project’s architecture (as determined by Landlord). In addition, Tenant’s name on such monument signage and Building-Top Sign shall be subject to the receipt of all required governmental permits and approvals (and the submission of copies thereof to Landlord), and shall be subject to all applicable Laws.

23.7 Cost and Maintenance. Landlord’s actual, out-of-pocket costs of the actual signs comprising Tenant’s name and/or logo on such monument sign and Building-Top Sign, as well as the installation, design, construction, and any and all other costs associated with Tenant’s name on such monument signage and/or the Building-Top Sign, including, without limitation, utility charges and hook-up fees (if applicable), permits, and maintenance and repairs, shall be the sole responsibility of Tenant provided that Tenant shall have the opportunity to preview estimates for any such amounts to be charged to Tenant; provided that Landlord shall reasonably cooperate with Tenant’s use of Common Areas to allow Tenant to install, operate, maintain and repair Tenant’s name on such monument sign and/or the Building- Top Sign. Should Tenant’s name and/or logo on such monument sign and/or the Building-Top Sign require repairs and/or maintenance, Landlord shall have the right to provide notice thereof to Tenant and Tenant (except as set forth above) shall cause such repairs and/or maintenance to commence to be performed within thirty (30) days after receipt of such notice from Landlord, at Tenant’s sole cost and expense; provided, however, if such repairs and/or maintenance are reasonably expected

to require longer than thirty (30) days to perform, Tenant shall commence such repairs and/or maintenance within such thirty (30) day period and shall thereafter diligently prosecute such repairs and maintenance to completion at Tenant’s sole cost and expense. Should Tenant fail to perform such repairs and/or maintenance within the periods described in the immediately preceding sentence, Landlord shall have the right to cause such work to be performed and to charge Tenant as Additional Rent for the actual out-of-pocket cost of such work plus interest at the Interest Rate from the date of Landlord’s payment of such actual costs to the date of Tenant’s reimbursement to Landlord. Tenant shall bear a pro rata share (based upon the number of tenants identified on such monument sign) of all of Landlord’s actual out-of-pocket costs of maintenance and operation of such monument sign and all such costs shall be paid by Tenant to Landlord as Additional Rent within ten (10) days of receipt of Landlord’s written demand therefore. Within a reasonable time following the expiration or earlier termination of this Lease (which shall in no event be later than thirty (30) days after such expiration or termination of this Lease), Tenant shall, at Tenant’s sole cost and expense, commence, and thereafter shall diligently pursue, the removal of Tenant’s name from such monument sign and the Building-Top Sign, and shall cause the areas in which such Tenant’s name on such monument sign and the Building-Top Sign was located to be restored to the condition existing immediately prior to the placement of such Tenant’s name on such monument signage and the installation of the Building-Top Sign. If Tenant fails to timely remove Tenant’s name from such monument sign and/or the Building-Top Sign or to restore the areas in which Tenant’s name on such monument sign and/or Building-Top Sign was located, as provided in the immediately preceding sentence, then Landlord may perform such work, and all actual costs reasonably incurred by Landlord in so performing, plus interest at the Interest Rate from the date of Landlord’s payment of such costs to the date of Tenant’s reimbursement to Landlord, shall be reimbursed by Tenant to Landlord within thirty (30) days after Tenant’s receipt of an invoice therefore. The terms of this Section 23.7 shall survive the expiration or earlier termination of this Lease.

23.8 Objectionable Name. In no event shall Tenant’s signage include, identify or otherwise refer to a name 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 a Comparable Building (an “Objectionable Name”). The parties hereby agree that the name “AnaptysBio, Inc.” or any reasonable derivation thereof, shall not be deemed an Objectionable Name.

ARTICLE 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 and is applicable to the Premises or Tenant’s use or occupancy of the Premises (collectively, “Applicable Laws”). At its sole cost and expense, Tenant shall promptly comply with all such Applicable Laws which relate to (i) Tenant’s use of the Premises for the Permitted Use (but which for purposes of this provision shall not apply to the extent resulting directly from the particular nature of Tenant’s tissue culture room and rodent vivarium uses) , (ii) the Alterations or the Improvements in the Premises, or (iii) the Base Building, but, as to the Base Building,

only to the extent such obligations are triggered by Tenant’s Alterations, the Improvements, or use of the Premises for other than the Permitted Use (but which for purposes of this provision shall not apply to the extent resulting directly from the particular nature of Tenant’s tissue culture room and rodent vivarium uses). Should any standard or regulation now or hereafter be imposed on 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. 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. 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 and materially affect the safety of Tenant’s employees or create a significant health hazard for Tenant’s employees. Landlord shall be permitted to include in Operating Expenses any costs or expenses incurred by Landlord under this Article 24 to the extent consistent with the terms of Section 4.2.4, above, and which are not inconsistent with the terms set forth in the Work Letter in connection with the Landlord Work.

ARTICLE 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 when due, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount plus any attorneys’ fees incurred by Landlord by reason of Tenant’s failure to pay Rent and/or other charges when due hereunder; provided, however, with regard to the first such failure in any twelve (12) month period, Landlord will waive such late charge to the extent Tenant cures such failure within five (5) business days following Tenant’s receipt of written notice from Landlord that the same was not received when due. The late charge shall be deemed Additional Rent and the right to require it shall be in 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 the “Interest Rate.” For purposes of this Lease, the “Interest Rate” shall be an annual rate equal to the lesser of (i) the annual “Bank Prime Loan” rate cited in the Federal Reserve Statistical Release Publication H. l 5(519), published weekly (or such other comparable index as Landlord and Tenant shall reasonably agree upon if such rate ceases to be published), plus two (2) percentage points, and (ii) the highest rate permitted by applicable law.

ARTICLE 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, unless a specific time period is otherwise stated in this Lease, Landlord may, but shall not be obligated to, 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: (i) sums equal to expenditures reasonably made and obligations reasonably incurred by Landlord in connection with the remedying by Landlord of Tenant’s defaults pursuant to the provisions of Section 26.1; (ii) sums equal to all losses, costs, liabilities, damages and expenses referred to in Article 10 of this Lease; and (iii) sums equal to all expenditures reasonably made and obligations reasonably incurred by Landlord in collecting or attempting to collect the Rent or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to law, including, without limitation, all legal fees and other amounts so expended. Tenant’s obligations under this Section 26.2 shall survive the expiration or sooner termination of the Lease Term.

ARTICLE 27

ENTRY BY LANDLORD

Landlord reserves the right at all reasonable times (during Building Hours with respect to items (i) and (ii) below) and upon at least twenty-four (24) hours prior 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 nine (9) months of the Lease Term, to prospective tenants; (iii) post notices of nonresponsibility; or (iv) 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; provided, however, except in the event of an emergency, Tenant shall have the option upon at least twelve (12) hours prior notice to Landlord to require Landlord’s entry be delayed by up to seventy-two (72) hours if Tenant deems such delay to be reasonably necessary to avoid disruption of Tenant’s business operations from within the Premises. Notwithstanding anything to the contrary contained in this Article 27, Landlord may enter the Premises at any time to (A) perform services required of Landlord; (B) take possession due to any breach of this Lease in the manner provided herein; and (C) perform any covenants of Tenant which Tenant fails to perform. 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; provided, however, except for (x) emergencies , (y) repairs, alterations, improvements or additions required by governmental or quasi-governmental authorities or court order or decree, or (z) repairs which are the obligation of Tenant hereunder, any such entry shall

be performed in a manner so as not to unreasonably interfere with Tenant’s use of the Premises and shall be performed after normal business hours if reasonably practical. With respect to items (y) and (z) above, Landlord shall use commercially reasonable efforts to not materially interfere with Tenant’s use of, or access to, the Premises. Tenant’s rights under the terms of Section 6.7 shall apply to Landlord’s entry under the terms of this Article 27 (other than an entry pursuant to the terms of item (B) above), and otherwise (except to the extent of Landlord’s express indemnification obligations under this Lease) Tenant hereby waives any claims for damages or for any injuries or inconvenience to or interference with Tenant’s business, lost profits, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby. For each of the above purposes, Landlord shall at all times have a key with which to unlock all the doors in the Premises, excluding Tenant’s vaults, safes and special security areas designated in advance by Tenant. 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. 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.

ARTICLE 28

TENANT PARKING

Tenant, Tenant’s Permitted Transferees and Tenant’s Occupants shall have the right to use, commencing on the Lease Commencement Date, the amount of parking passes set forth in Section 9 of the Summary, on a monthly basis throughout the Lease Term, which parking passes shall pertain to the Project parking facility. Tenant hereby acknowledges and agrees that notwithstanding the permitted occupancy density of five (5) persons per each one thousand (1,000) rentable square feet of the Premises as more particularly set forth in Section 5.2, above, in no event shall Tenant be entitled to park automobiles anywhere in the Project parking facility in a total amount that would at anytime exceed an amount equal to three and one-half (3¹⁄₂) unreserved parking passes for every one thousand (1,000) rentable square feet of the Premises. Tenant shall not be obligated to pay any fee for automobile parking passes during the initial Lease Term or any Option Term; provided, however, to the extent not included in Tax Expenses, Tenant shall be responsible for the full amount of any taxes imposed by any governmental authority in connection with use of the parking facility by Tenant. Tenant’s continued right to use the parking passes is conditioned upon Tenant abiding by all rules and regulations which are prescribed from time to time for the orderly operation and use of the parking facility where the parking passes are located, including any sticker or other identification system established by Landlord, Tenant’s cooperation in seeing that Tenant’s employees and visitors also comply with such rules and regulations and Tenant not being in default under this Lease. Landlord specifically reserves the right to change the size, configuration, design, layout and all other aspects of the Project parking facility at any time and Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of Rent under this Lease, from time to time, temporarily close-off or restrict access to the Project parking facility for purposes of permitting or facilitating any such construction, alteration or improvements; provided, however, in no event shall the number of parking passes available for

Tenant’s use decrease below the number of parking passes expressly allocated to Tenant under this Lease. Landlord may delegate its responsibilities hereunder to a parking operator in which case such parking operator shall have all the rights of control attributed hereby to the Landlord. The parking passes provided to Tenant pursuant to this Article 28 are provided to Tenant solely for use by Tenant’s own personnel and such passes may not be transferred, assigned, subleased or otherwise alienated by Tenant without Landlord’s prior approval.

ARTICLE 29

MISCELLANEOUS PROVISIONS

29.1 Terms; Captions. The words “Landlord” and “Tenant” as used herein shall include the plural as well as the singular. The necessary grammatical changes required to make the provisions hereof apply either to corporations or partnerships or individuals, men or women, as the case may require, shall in all cases be assumed as though in each case fully expressed. The captions of Articles and Sections are for convenience only and shall not be deemed to limit, construe, affect or alter the meaning of such Articles and Sections.

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 windows of the Premises are temporarily darkened or the light or view therefrom is obstructed by reason of any repairs, improvements, maintenance or cleaning in or about the Project, the same shall be without liability to Landlord and without any reduction or diminution of Tenant’s obligations under this Lease.

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 materially and 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) 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) 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 not accrued as of the date of the transfer (provided such transferee assumes such obligations in writing) 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. Tenant further acknowledges that Landlord may assign its interest in this Lease to a mortgage lender as additional security and agrees that such an assignment shall not release Landlord from its obligations hereunder and that Tenant shall continue to look to Landlord for the performance of its obligations hereunder.

29.6 Prohibition Against Recording or Publication. 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 or otherwise published 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. To the extent Landlord has delivered a written notice to Tenant pursuant to the terms of Section 19.1.1 of this Lease (and until the amounts represented by such notice, together with all other then-outstanding amounts due and owning under this Lease, are satisfied), 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 Land lord, in its sole discretion, may elect, it nevertheless being acknowledged that Tenant may be free to make any such payments “under protest,” and such payments shall remain subject to successful contest by Tenant over any obligations in dispute.

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.

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 net interest of Landlord in the Project (following payment of any outstanding liens and/or mortgages, whether attributable to sales or insurance proceeds or otherwise). 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, neither Landlord nor the Landlord Parties shall be liable under any circumstances for injury or damage to, or interference with, Tenant’s business, including but not limited 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.

29.14 Entire Agreement. It is understood and acknowledged that there are no oral agreements between the pa(ties 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.

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, 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 charges to be paid by Tenant pursuant to this Lease and except as to Tenant’s obligations under Articles 5 and 24 of 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.

Any Notice will be deemed given (i) three (3) days after the date it is posted if sent by Mail, (ii) the date the telecopy is transmitted, (iii) the date the overnight courier delivery is made, or (iv) the date personal delivery is made or attempted to be made. If Tenant is notified of the identity and address of Landlord’s mortgagee or ground or underlying lessor, Tenant shall give to such mortgagee or ground or underlying lessor written notice of any default by Landlord under the terms of this Lease by registered or certified mail, and such mortgagee or ground or underlying lessor shall be given a reasonable opportunity to cure such default prior to Tenant’s exercising any remedy available to Tenant.

Landlord shall pay the Brokers pursuant to the terms of separate commission agreements. 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.

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.

29.27 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.

29.30 Building Renovations. It is specifically understood and agreed that Landlord has made no representation or warranty to Tenant and has no obligation and has made no promises to alter, remodel, improve, renovate, repair or decorate the Premises, Building, or any part thereof and that no representations respecting the condition of the Premises or the Building have been made by Landlord to Tenant except as specifically set forth herein or in the Work Letter. However, Tenant hereby acknowledges that Landlord is currently renovating or may during the Lease Term renovate, improve, alter, or modify (collectively, the “Renovations”) the Project, the Building and/or the Premises including without limitation the parking structure, common areas, systems and equipment, roof, and structural portions of the same, which Renovations may include, without limitation, (i) installing sprinklers in the Building common areas and tenant

Tenant hereby agrees that such Renovations and Landlord’s actions in connection with such Renovations shall in no way constitute a constructive eviction of Tenant nor, except as expressly set forth in Section 6.7 above, entitle Tenant to any abatement of Rent. Landlord shall have no responsibility or for any reason be liable to Tenant for any direct or indirect injury to or interference with Tenant’s business arising from the Renovations, nor shall Tenant be entitled to any compensation or damages from Landlord for loss of the use of the whole or any part of the Premises or of Tenant’s personal property or improvements resulting from the Renovations or Landlord’s actions in connection with such Renovations, or for any inconvenience or annoyance occasioned by such Renovations or Landlord’s actions. Landlord shall perform such Renovations in compliance with the terms of this Lease, and shall use commercially reasonable efforts to have all such work performed on a continuous basis, and once started, to be completed reasonably expeditiously, with such work being organized, conducted and scheduled in a manner which will minimize any interference to Tenant’s business operations in the Premises.

In addition, the physical appearance and the size of the Rooftop Equipment shall be subject to Landlord’s reasonable approval, the location of any such installation of the Rooftop Equipment shall be designated by Tenant subject to Landlord’s reasonable approval and Landlord may require Tenant to install screening around such Rooftop Equipment, at Tenant’s sole cost and expense, as reasonably designated by Landlord.

Such Rooftop Equipment shall, in all instances, comply with applicable governmental laws, codes, rules and regulations.

29.34.3 Tenant shall maintain such Rooftop Equipment, at Tenant’s sole cost and expense. Tenant shall remove such Rooftop Equipment upon the expiration or earlier termination of the “Lease, or, in the event Tenant no longer occupies the Premises, then upon the termination of Tenant’s rights under this Section 29.34, and shall return the affected portion of the rooftop and the Premises to the condition the rooftop and the Premises would have been in had no such Rooftop Equipment been installed (reasonable wear and tear excepted).

29.34.4 Tenant shall not be entitled to assign, sublease, license or otherwise transfer all or any portion of its right to use such Rooftop Equipment (other than in connection with an assignment of this Lease under the terms of Article 14), nor shall Tenant be permitted to receive any revenues, fees or any other consideration for the use of such Rooftop Equipment by an unrelated third party. Tenant’s right to install such Rooftop Equipment shall be non-exclusive, and Tenant hereby expressly acknowledges Landlord’s continued right (i) to itself utilize any rooftop space, and (ii) to re-sell, license or lease any rooftop space to an unaffiliated third party; provided, however, such Landlord (or third-party) use shall not materially interfere with (or preclude the installation of) Tenant’s Rooftop Equipment.

IMPROVEMENTS

2.1 Improvement Allowance. Tenant shall be entitled to a one-time improvement allowance (the “Improvement Allowance”) in the amount of Thirteen and 00/100 Dollars ($13.00) per rentable square foot of the Premises for the costs relating to the initial design and construction of the improvements which are permanently affixed to the Premises (the “Improvements”). In no event shall Landlord be obligated to make disbursements pursuant to this Work Letter in the event that Tenant fails to immediately pay any portion of the “Over-Allowance Amount,” as defined in Section 4.2.l, nor shall Landlord be obligated to pay a total amount which exceeds the sum of the Improvement Allowance and the cost of the Landlord Work. Notwithstanding the foregoing or any contrary provision of this Lease, all Improvements shall be deemed Landlord’s property under the terms of this Lease except to the extent otherwise expressly excluded from Landlord’s property pursuant to the TCCs of Section 8.6 of this Lease. Any unused portion of the Improvement Allowance remaining as of June 30, 2013 shall remain with Landlord and Tenant shall have no further right thereto.

2.2 Disbursement of the Improvement Allowance. Except as otherwise set forth in this Work Letter, the Improvement Allowance shall be disbursed by Landlord (each of which disbursements shall be made pursuant to Landlord’s disbursement process, including, without limitation, Landlord’s receipt of invoices for all costs and fees described herein) for costs related to the construction of the Improvements and for the following items and costs (collectively, the “Improvement Allowance Items”):

2.2.l The cost of any changes to the Construction Drawings or Improvements required by all applicable building codes (the “Code”);

2.3 Building Standards. Landlord has established or may establish specifications for certain Building standard components to be used in the construction of the Improvements in the Premises. The quality of Improvements shall be equal to or of greater quality than the quality of such Building standards, provided that Landlord may, at Landlord’s option, require the Improvements to comply with certain Building standards. Landlord may make changes to said specifications for Building standards from time to time.

2.4 Removal of Improvements. Other than with respect to Above Standard Improvements as set forth in this Section 2.4, Landlord shall not require Tenant to remove from the Premises any Improvements (to the extent the same are construction in the Premises in accordance with the terms of this Work Letter) upon the expiration or any earlier termination of this Lease. “Above Standard Improvements” shall mean any part of the Improvements which do not constitute normal and customary general office improvements as reasonably determined by Landlord (Above Standard Improvements shall include, without limitation, improvements such as voice, data and other cabling, raised floors, floor penetrations, any installations outside the Premises, or any areas requiring floor reinforcement, personal baths and showers, vaults, rolling file systems, any vivariums or vivarium related improvements, laboratory space, and structural alterations of any type), and identified by Landlord for removal at the time of Landlord’s review and approval (to the extent such approval is granted) of the Final Space and/or the Final Working Drawings. In the event so identified by Landlord, Tenant shall remove such Above Standard Improvements upon the expiration or earlier termination of this Lease as more particularly set forth in Section 8.5 of this Lease.

SECTION 3

CONSTRUCTION DRAWINGS

3.1 Selection of Architect/Construction Drawings. Landlord shall retain, on behalf of Tenant, FPBA Architects (the “Architect”) to prepare the “Construction Drawings,” as that term is defined in this Section 3.1. Landlord shall retain, on behalf of Tenant, engineering consultants and/or design-build consultants designated by Landlord (the “Engineers”) to prepare all plans and engineering working drawings relating to the structural, mechanical, electrical, plumbing and HYAC work of the Improvements and any relevant components of the Landlord Work. The plans and drawings to be prepared by Architect and the Engineers hereunder shall be known collectively as the “Construction Drawings.” All Construction Drawings shall comply with the drawing format and specifications as determined by Landlord, and shall be subject to Landlord’s approval as more particularly set forth in Sections 3.2 and 3.3, below. Notwithstanding Landlord’s retention of the Architect and Engineers, Tenant shall be responsible for, and shall fully cooperate and coordinate in good faith with Landlord, the Architect and the Engineers to supply all of the necessary information within Tenant’s possession to allow the Architect and the Engineers to initially prepare and then complete, the Construction Drawings. Landlord hereby agrees (at no cost to Landlord) to cooperate, on a commercially reasonable basis, with Tenant to assist Tenant in the preparation of the Construction Drawings. Landlord’s review of the

Construction Drawings applicable to the Improvements (as opposed to Landlord Work) and as set forth in this Section 3, shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same, for quality, design, Code compliance or other like matters. Accordingly, notwithstanding that any Improvement-related portions of such Construction Drawings are reviewed by Landlord, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord, Landlord shall have no liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained in such portions of the Construction Drawings, and Tenant’s waiver and indemnity set forth in this Lease shall specifically apply to such portions of the Construction Drawings.

3.2 Final Space Plan. On or before the date set forth in Schedule 1, attached hereto, Tenant and the Architect shall prepare the final space plan for Improvements in the Premises (collectively, the “Final Space Plan”), which Final Space Plan shall include a layout and designation of all offices, rooms and other partitioning, their intended use, and equipment to be contained therein, and shall deliver four (4) hard copies signed by Tenant to Landlord for Landlord’s approval, and concurrently with Tenant’s delivery of such hard copies, Tenant shall send to Landlord via electronic mail one (1) .pdf electronic copy of such Final Space Plan. Landlord shall advise Tenant within five (5) business days after Landlord’s receipt of the Final Space Plan for the Premises if the same is unsatisfactory or incomplete in any respect; provided, however, Landlord shall only disapprove such Final Space Plan to the extent of a Design Problem. Landlord shall set forth with reasonable specificity in what respect the Final Space Plan is unsatisfactory or incomplete. If Tenant is so advised, Tenant shall promptly cause the Final Space Plan to be revised within five (5) business days in order to correct any deficiencies or other matters Landlord may reasonably require, and immediately thereafter Architect shall promptly re-submit the Final Space Plan to Landlord for its approval. Such procedure shall continue (except that the time frame to consent to any revisions shall be shortened to three (3) business days) until the Final Space Plan is approved by Landlord. For purposes of this Work Letter, a “Design Problem” shall be any aspect of the Final Space Plan that (a) have an adverse effect on the structural integrity of the Building; (b) are not in compliance with Applicable Law; (c) have an adverse effect on the systems and equipment of the Building; (d) have an effect on the exterior appearance of the Building; (e) do not comply with the Building standards identified in Section 2.3 of this Work Letter, (f) cause unreasonable interference with the normal and customary operations of any other tenant in the Building, or (g) has incomplete, missing or inaccurate information.

3.3 Final Working Drawings. On or before the date set forth in Schedule 1, Tenant, the Architect and the Engineers shall complete the architectural and engineering drawings for the Premises, and the final architectural working drawings in a form which is complete to allow subcontractors to bid on the work and to obtain all applicable permits (collectively, the “Final Working Drawings”) and shall submit four (4) hard copies signed by Tenant of the Final Working Drawings to Landlord for Landlord’s approval, and concurrently with Tenant’s delivery of such hard copies, Tenant shall send to Landlord via electronic mail one (1) .pdf electronic copy of such Final Working Drawings; provided, however, Landlord shall only disapprove of the Final Working Drawings to the extent the same are not consistent with, or a logical evolution of, the Final Space Plan. Landlord shall advise Tenant within five (5) business days after Landlord’s receipt of all of the Final Working Drawings, either (i) approve the Final Working Drawings, (ii) approve the Final Working Drawings subject to specified

conditions, which conditions must be stated in a reasonably clear and complete manner, or (iii) disapprove and return the Construction Drawings to Tenant with requested revisions. If Landlord disapproves the Final Working Drawings, Tenant shall promptly cause the Final Working Drawings to be revised within five (5) business days in order to correct any deficiencies or other matters Landlord may reasonably require, and immediately thereafter Architect shall promptly re-submit the Final Space Plan to Landlord for its approval based upon the criteria set forth in this Section 3.3, within five (5) business days after Landlord receives such resubmitted Final Working Drawings. Such procedure shall be repeated until the Final Working Drawings are approved.

3.4 Permits. The Final Working Drawings shall be approved by Landlord (the “Approved Working Drawings”) prior to the commencement of the construction of the Improvements. Landlord shall cause the Approved Working Drawings to be immediately submitted to the appropriate municipal authorities for all applicable building and other permits necessary to allow “Contractor,” as that term is defined in Section 4.1, below, to commence and fully complete the construction of the Improvements and the relevant Landlord Work (the “Permits”). No changes, modifications or alterations in the Approved Working Drawings may be made without the prior written consent of Landlord, provided that Landlord may withhold its consent, in its sole discretion, to any change in the Approved Working Drawings if such change would directly or indirectly delay the “Substantial Completion” of the Premises as that term is defined in Section 5.l of this Work Letter.

3.5 Time Deadlines. Landlord and Tenant shall use their best, good faith, efforts and all due diligence to cooperate with the Architect, the Engineers, and each other to complete all phases of the Construction Drawings and the permitting process and to receive the permits, and with Contractor for approval of the “Cost Proposal,” as that term is defined in Section 4.2 of this Work Letter, as soon as possible after the execution of the Lease, and, in that regard, shall meet with Landlord on a scheduled basis to be mutually and reasonably determined by Landlord and Tenant, to discuss Tenant’s progress in connection with the same. The applicable dates for approval of items, plans and drawings as described in this Section 3, Section 4, below, and in this Work Letter are set forth and further elaborated upon in Schedule 1 (the “Time Deadlines”), attached hereto. Tenant agrees to comply with the Time Deadlines.

3.6 Electronic Approvals. Notwithstanding any provision to the contrary contained in the Lease or this Work Letter, Landlord may, in Landlord’s sole and absolute discretion, transmit or otherwise deliver any of the approvals required under this Work Letter via electronic mail to Tenant’s representative identified in Section 5.1 of this Work Letter, or by any of the other means identified in Section 29.18 of this Lease.

SECTION 4

CONSTRUCTION OF THE IMPROVEMENTS

4.1 Contractor. Landlord shall retain DPR Construction as the contractor (the “Contractor”) to construct the Improvements.

4.2 Cost Proposal. After the Approved Working Drawings are signed by Landlord and Tenant, Landlord shall provide Tenant with a cost proposal in accordance with the Approved Working Drawings, which cost proposal shall include, as nearly as possible, the cost of all Improvement Allowance Items to be incurred by Tenant in connection with the design and construction of the Improvements (the “Cost Proposal”). Tenant shall approve and deliver the Cost Proposal to Landlord within five (5) business days of the receipt of the same, and upon receipt of the same by Landlord, Landlord shall be released by Tenant to purchase the items set forth in the Cost Proposal and to commence the construction relating to such items. The date by which Tenant must approve and deliver the Cost Proposal to Landlord shall be known hereafter as the “Cost Proposal Delivery Date”. Notwithstanding the foregoing, Tenant shall have the one-time right to object to such Cost Proposal prior to the Cost Proposal Delivery Date by providing Landlord with written notice of such objection, and which notice shall specifically identify, in detail, the proposed changes that Tenant desires such the Cost Proposal would be acceptable to Tenant, as well as Tenant’s desired pricing parameters. In the event Tenant so objects to the Cost Proposal, Tenant shall work directly with the Architect and/or Engineers to revise the Final Space Plan and/or Approved Working Drawings (as applicable), and resubmit the Final Space Plan and/or Approved Working Drawings (as applicable) to Landlord within three (3) business days following Tenant’s objection, which revised Final Space Plan and/or Approved Working Drawings (as applicable) shall be subject to Landlord’s approval in accordance with the provisions of Section 3 of this Work Letter, and following the approval of the revised Final Space Plan and/or Approved Working Drawings (as applicable) by Landlord and Tenant, Landlord shall submit a revised cost proposal “Revised Cost Proposal” to Tenant for its approval in accordance with the terms set forth above in this Section 4.2. The date by which Tenant must approve and deliver the Cost Proposal to Landlord shall be known hereafter as the “Revised Cost Proposal Delivery Date.” In the event Tenant fails to approve or timely object to the original Cost Proposal or Revised Cost Proposal on or before the Cost Proposal Delivery Date, or the Revised Cost Proposal Delivery Date, respectively, such failures shall be deemed to be Tenant delays subject to the terms of Section 5.2 of this Work Letter.

4.3 Construction of Improvements by Contractor under the Supervision of Landlord.

4.3.1 Over-Allowance Amount. On the Cost Proposal Delivery Date, Tenant shall deliver to Landlord cash in an amount (the “Over-Allowance Amount”) equal to the difference between (i) the amount of the Cost Proposal and (ii) the amount of the Improvement Allowance. The Over-Allowance Amount shall be disbursed by Landlord on a pro-rata basis along with any then remaining portion of the Improvement Allowance, and such disbursement shall be pursuant to the same procedure as the Improvement Allowance. In the event that, after the Cost Proposal Delivery Date, any revisions, changes, or substitutions shall be made to the Construction Drawings or the Improvements, any additional costs which arise in connection with such revisions, changes or substitutions or any other additional costs shall be paid by Tenant to

Landlord immediately upon Landlord’s request as an addition to the Over-Allowance Amount. In addition, if the Final Working Drawings or any amendment thereof or supplement thereto shall require alterations in the Base Building (as contrasted with the Improvements), and if Landlord in its sole and exclusive discretion agrees to any such alterations, and notifies Tenant of the need and cost for such alterations, then Tenant shall pay the cost of such required changes in advance upon receipt of notice thereof (but only to the extent that no Improvement Allowance funds remain unallocated and undisbursed and are available to pay for the same). Tenant shall pay all direct architectural and/or engineering fees in connection therewith, plus six percent (6%) of such direct costs for Landlord’s servicing and overhead. In the event that Tenant fails to deliver the Over-Allowance Amount as provided in this Section 4.3.1, then Landlord may, at its option, cease work in the Premises until such time as Landlord receives payment of the Over- Allowance Amount (and such failure to deliver shall be treated as a Tenant delay in accordance with the terms of Section 5.2 below).

4.3.2 Landlord’s Retention of Contractor. Landlord shall independently retain Contractor to construct the Improvements in accordance with the Approved Working Drawings and the Cost Proposal and Landlord shall supervise the construction by Contractor, and Tenant shall pay a construction supervision and management fee (the “Landlord Supervision Fee”) to Landlord in an amount equal to the product of (i) six percent (6%) and (ii) an amount equal to the Improvement Allowance plus the Over-Allowance Amount (as such Over-Allowance Amount may increase pursuant to the terms of this Work Letter).

4.3.3 Contractor’s Warranties and Guaranties. Landlord hereby assigns to Tenant all warranties and guaranties by Contractor relating to the Improvements, and Tenant hereby waives all claims against Landlord relating to, or arising out of the construction of, the Improvements.

4.3.4 Additional Items. Landlord may elect to cause Contractor and Architect to cause a Notice of Completion to be recorded in the office of the County Recorder of the county in which the Building is located in accordance with Section 3093 of the Civil Code of the State of California or any successor statute.

SECTION 5

DELAY OF SUBSTANTIAL COMPLETION OF PREMISES;

EXTENSION OF LEASE COMMENCEMENT DATE

5.1 Delay of the Substantial Completion of the Premises. Except as provided in this Section 5.1, the Lease Commencement Date shall occur as set forth in the Lease and Section 5.2, below. If there shall be a delay or there are delays in the Substantial Completion of the Improvements as a direct, indirect, partial, or total result of:

5.1.1 Tenant’s failure to comply with the Time Deadlines;

5.1.2 Tenant’s failure to timely approve any matter requiring Tenant’s approval;

5.1.3 A breach by Tenant of the terms of this Work Letter or the Lease;

5.1.4 Changes in any of the Construction Drawings after disapproval of the same by Landlord or because the same do not comply with Code or other applicable laws;

5.1.5 Tenant’s request for changes in the Approved Working Drawings;

5.1.7 Changes to the Base Building required by the Approved Working Drawings;

5.1.8 Tenant’s use of specialized or unusual improvements and/or delays m obtaining Permits due thereto;

5.1.9 Any failure by Tenant to timely pay to Landlord any portion of the Over-Allowance Amount; or

5.1.10 Any other acts or omissions of Tenant, or its agents, or employees;

then, notwithstanding anything to the contrary set forth in the Lease or this Work Letter and regardless of the actual date of the Substantial Completion of the Improvements, Substantial Completion of the Improvements shall be deemed to have occurred on the date such Substantial Completion of the Improvements would have occurred if no Tenant delay or delays, as set forth above, had occurred.

5.2 Substantial Completion: Extension of Lease Commencement Date. For purposes of this Lease, and subject to adjustment for any Tenant delay or delays as set forth in Section 5.1 of this Work Letter above, “Substantial Completion” of the Improvements shall occur upon the completion of construction of the Improvements in the Premises pursuant to the Approved Working Drawings, with the exception of any punch list items and any tenant fixtures, work- stations, built-in furniture, or equipment to be installed by Tenant or under the supervision of Contractor. To the extent Substantial Completion of the Improvements has not occurred on or before August 16, 2011, the Lease Commencement Date otherwise set forth in Section 3.2 of the Summary to this Lease shall be extended on a day-for-day basis (in which event any other dates calculated based upon the Lease Commencement Date, such as the Lease Expiration Date and the Rent Abatement Period, shall be adjusted accordingly).

SECTION 6

MISCELLANEOUS

6.1 Tenant’s Entry Into the Premises Prior to Substantial Completion. Provided that Tenant and its agents do not interfere with construction of the Improvements, Landlord shall allow Tenant access to the Premises up to sixty (60) days prior to the Substantial Completion of the Improvements for the purpose of Tenant installing over standard equipment or fixtures (including Tenant’s data and telephone equipment) in the Premises, which installation shall be

subject to Tenant’s receipt, at Tenant’s sole cost and expense, of any required approvals and/or permits from the applicable governmental agencies. Prior to Tenant’s entry into the Premises as permitted by the terms of this Section 6.1, Tenant shall submit a schedule to Landlord and Contractor, for their approval, which schedule shall detail the timing and purpose of Tenant’s entry. Additionally, all of Tenant’s Agents, as that term is defined in Section 6.5, below, shall carry worker’s compensation insurance covering all of their respective employees, and shall also carry public liability insurance, including property damage, all with limits, in form and with companies as are required to be carried by Tenant as set forth in this Lease. Certificates for all insurance carried pursuant to this Section 6.1 shall be delivered to Landlord prior to Tenant’s entry into the Premises. Tenant’s Agents shall maintain all of the foregoing insurance coverage in force until the Improvements are fully completed and accepted by Landlord. All policies carried under this Section 6.1 shall insure Landlord and Tenant, as their interests may appear, as well as Contractor and Tenant’s Agents. All insurance, except Workers’ Compensation, maintained by Tenant’s Agents shall preclude subrogation claims by the insurer against anyone insured thereunder. Such insurance shall provide that it is primary insurance as respects the owner and that any other insurance maintained by owner is excess and noncontributing with the insurance required hereunder. Tenant shall hold Landlord harmless from and indemnify, protect and defend Landlord against any loss or damage to the Building or Premises and against injury to any persons caused by Tenant’s actions pursuant to this Section 6.1.

6.2 Freight Elevators.

6.3 Tenant’s Representative. Tenant has designated Ed Marples as its sole representative with respect to the matters set forth in this Work Letter (whose e-mail address for the purposes of this Work Letter is ***@***), who, until further notice to Landlord, shall have full authority and responsibility to act on behalf of the Tenant as required in this Work Letter.

6.4 Landlord’s Representatives. Landlord has designated Richard Mount and Jake Brehm as its sole representative (the “Project Managers”) with respect to the matters set forth in this Work Letter (whose e-mail addresses for the purposes of this Work Letter are ***@*** and ***@***, respectively), who shall each be responsible for the implementation of all Improvements to be performed by Landlord in the Premises. With regard to all matters involving such Improvements, Tenant shall communicate with the Project Managers rather than with the Contractor. Landlord shall not be responsible for any statement, representation or agreement made between Tenant and the Contractor or any subcontractor. It is hereby expressly acknowledged by Tenant that such Contractor is not Landlord’s agent and has no authority whatsoever to enter into agreements on Landlord’s behalf or otherwise bind Landlord. The Project Managers will furnish Tenant with notices of substantial completion, cost estimates for above standard Improvements, Landlord’s approvals or disapprovals of all documents to be prepared by Tenant pursuant to this Work Letter and changes thereto.

6.5 Tenant’s Agents. Tenant shall not use (and upon notice from Landlord shall cease using) contractors, services, workmen, labor, materials or equipment (individually or collectively, “Labor Disturbing Services”) 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. Alternatively, at Landlord’s sole election, Landlord may require that Tenant shall cease utilizing the applicable Labor Disturbing Services during Building Hours, and may only utilize such Labor Disturbing Services during hours other than Building Hours. All contractors, subcontractors, laborers, materialmen, and suppliers retained directly by Tenant shall be the “Tenant’s Agents”).

6.6 Time is of the Essence. Time is of the essence under this Work Letter. Unless otherwise indicated, all references herein to a “number of days” shall mean and refer to calendar days.

6.7 Tenant’s Lease Default. Notwithstanding any provision to the contrary contained in the Lease or this Work Letter, if any default (beyond the applicable notice and cure period set forth in this Lease or this Work Letter) by Tenant under the Lease or this Work Letter (including, without limitation, any failure by Tenant to fund any portion of the Over-Allowance Amount) occurs at any time on or before the Substantial Completion of the Improvements, then (i) in addition to all other rights and remedies granted to Landlord pursuant to the Lease, Landlord shall have the right to withhold payment of all or any portion of the Improvement Allowance and/or Landlord may, without any liability whatsoever, cause the cessation of construction of the Improvements (in which case, Tenant shall be responsible for any delay in the Substantial Completion of the Improvements and any costs occasioned thereby), and (ii) all other obligations of Landlord under the terms of the Lease and this Work Letter shall be forgiven until such time as such default is cured pursuant to the terms of this Lease.

6.8 Punch List. Promptly following the Substantial Completion of the Improvements, a representative of Tenant and a representative of Landlord and/or the Architect shall perform a joint walk-through inspection of the Improvements in the Premises to identify any “punchlist” items of known or apparent deficiencies or incomplete work required to be corrected or completed by Landlord pursuant to the Approved Working Drawings, which items Landlord shall repair or correct no later than thirty (30) days after the date of such walk-through (unless the nature of such repair or correction is such that more than thirty (30) days are required for completion, in which case, Landlord shall commence such repair or correction work within such thirty (30) day period and diligently prosecute the same to completion).

MARKET RENT DETERMINATION FACTORS

When determining Market Rent, the following rules and instructions shall be followed.

1. RELEVANT FACTORS. The “Comparable Transactions” shall be the “Net Equivalent Lease Rates” per rentable square foot, at which tenants, are, pursuant to transactions consummated within twelve (12) months prior to the commencement of the Option Term, leasing non-sublease, non-encumbered space comparable in location and quality to the Premises containing a square footage comparable to that of the Premises for a term of five (5) years, in an arm’s-length transaction, which comparable space is located in “Comparable Buildings.” The terms of the Comparable Transactions shall be calculated as a “Net Equivalent Lease Rate” pursuant to the terms of this Exhibit H, and shall take into consideration only the following terms and concessions: (i) the rental rate and escalations for the Comparable Transactions, the amount of parking rent per parking permit paid in the Comparable Transactions, if any, operating expense and tax protection granted in such Comparable Transactions such as a base year or expense stop (although for each such Comparable Transaction the base rent shall be adjusted to a triple net base rent using reasonable estimates of operating expenses and taxes as determined by Landlord for each such Comparable Transaction); (iv) rental abatement concessions, if any, being granted such tenants in connection with such comparable space, (v) any “Renewal Allowance,” as defined herein below, to be provided by Tenant in connection with the Option Term as compared to the improvements or allowances provided or to be provided in the Comparable Transactions, taking into account the contributory value of the existing improvements in the Premises, such value to be based upon the age, design, quality of finishes, and layout of the existing improvements, and (vi) all other monetary concessions (including the value of any signage), if any, being granted such tenants in connection with such Comparable Transactions. Notwithstanding any contrary provision hereof, in determining the Market Rent, 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 improvements, or any commission paid or not paid in connection with such Comparable Transaction. The Market Rent shall include adjustment of the stated size of the Premises based upon the standards of measurement utilized in the Comparable Transactions. The Market Rent shall additionally be subject to appropriate adjustments (if any) to account for differences in the then-existing financial condition of the Tenant vis-a-vis the subject tenants under the Comparable Transactions and taking into account any applicable credit enhancements (e.g., security deposits, letters of credit, guaranties, etc.).

2. TENANT SECURITY. The Market Rent shall additionally include a determination as to whether, and if so to what extent, Tenant must provide Landlord with financial security, such as an enhanced security deposit, a letter of credit or guaranty, for Tenant’s Rent obligations during the Option Term; provided, however, Tenant shall only be obligated to provide additional financial security to the extent Tenant’s then-existing financial condition is materially worse than those existing as of the date of this Lease. Such determination shall be made by reviewing the extent of financial security then generally being imposed in

- 5 -

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, and giving reasonable consideration to Tenant’s prior performance history during the Lease Term).

3. RENEWAL IMPROVEMENT ALLOWANCE. Notwithstanding anything to the contrary set forth in this Exhibit H, once the Market Rent for the Option Term is determined as a Net Equivalent Lease Rate, if, in connection with such determination, it is deemed that Tenant is entitled to an improvement or comparable allowance for the improvement of the Premises, (the total dollar value of such allowance shall be referred to herein as the “Renewal Allowance”), Landlord shall pay the Renewal Allowance to Tenant pursuant to a commercially reasonable disbursement procedure determined by Landlord and the terms of Article 8 of this Lease and the rental rate component of the Market Rent shall be increased to be a rental rate which takes into consideration that Tenant will receive payment of such Renewal Allowance and, accordingly, such payment (with interest at a then-applicable, commercially reasonable amortization rate) shall be factored into the base rent component of the Market Rent. Notwithstanding any provision to the contrary, in no event shall Tenant be obligated to accept a Renewal Allowance once the Market Rent has been determined, and in the event Tenant elects not to accept such a Renewal Allowance, the Market Rent shall be adjusted accordingly to take account of such non-election.

4. COMPARABLE BUILDINGS. For purposes of this Lease, the term “Comparable Buildings” shall mean first-class multi-tenant occupancy research and development buildings (based on the approximate percentage of lab to office buildout) which are comparable to the Building in terms of age (based upon the date of completion of construction or major renovation), quality of construction, level of services and amenities (including, but not limited to, the type (e.g., surface, covered, subterranean) and amount of parking), size and appearance, and are located in the “Comparable Area,” which is the “Sorrento Mesa, University Towne Center, Torrey Pines and Del Mar/Carmel Valley Area.” The “Sorrento Mesa, University Towne Center, Torrey Pines and Del Mar/Carmel Valley Area” shall be the area containing Comparable Buildings which have reasonably comparable freeway access to the Project and which are within an area bounded by SR-52 on the South side, SR-56 on the North side, I-15 on the East side, and the Pacific Ocean on the West side.

Notwithstanding any provision to the contrary set forth in the Lease (specifically including Section 2.2 of the Summary attached to the Lease), Landlord and Tenant acknowledge and agree that the aggregate rentable square footage of the Premises is 25,450 rentable square feet of space consisting of (i) 25,296 rentable square feet commonly known as Suite 200 and located on the second (2^nd) floor of the Building, and (ii) 154 rentable square feet of space on the first floor of the Building. Effective as of September 1, 2016 and continuing throughout the “Extended Term” (as that term is defined in Section 3.1 below), the Premises shall be deemed to contain 25,450 rentable square feet of space for all purposes under the Lease.

2.2. Condition of the Premises. Landlord and Tenant acknowledge that Tenant has been occupying the Premises pursuant to the Lease, and therefore Tenant continues to accept the Premises in its presently existing, “as is” condition. Except as expressly set forth in this Section 2.2, Landlord shall not be obligated to provide or pay for any improvement work or services related to the improvement of the Premises. Notwithstanding the foregoing, Landlord agrees that Landlord shall, on a one (1)-time basis and at Landlord’s sole cost and expense, perform the following work utilizing Building standard methods, materials and finishes: (i) replace the existing supplemental HVAC unit which services the server room located in the Premises with a new HVAC unit which is reasonably comparable to the existing supplemental HVAC unit (the exact make, model and specifications of which shall be reasonably and mutually agreed upon by Landlord and Tenant), and (ii) balance and service the HVAC system which services the entire Premises (the extent and scope of which shall be determined in Landlord’s reasonable discretion) (collectively, the “Landlord’s Work”). Tenant shall provide a clear working area for Landlord’s Work, as necessary, and upon Landlord’s reasonable request, move any furniture, trade fixtures and personal property in the Premises in such a manner as to accommodate Landlord’s

performance of Landlord’s Work. Tenant hereby agrees that the performance of Landlord’s Work shall in no way constitute a constructive eviction of Tenant nor entitle Tenant to any abatement of rent. Landlord shall have no responsibility or for any reason be liable to Tenant for any direct or indirect injury to or interference with Tenant’s business arising from Landlord’s Work, nor shall Tenant be entitled to any compensation or damages from Landlord for (i) any loss or damage to Tenant’s furniture, trade fixtures or personal property sustained in connection with Landlord’s performance of Landlord’s Work or the relocation of any such items in order to perform Landlord’s Work, or (ii) loss of use of the whole or any part of the Premises or of Tenant’s personal property or improvements resulting from Landlord’s Work or Landlord’s actions (or the actions of Landlord’s contractors, employees and/or agents) in connection with Landlord’s Work, or for any inconvenience or annoyance occasioned by Landlord’s Work or Landlord’s actions (or the actions of Landlord’s contractors, employees and/or agents) in connection with Landlord’s Work. Further, Tenant acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty regarding the condition of the Premises or the Building with respect to the suitability of the same for the conduct of Tenant’s business. Tenant acknowledges and agrees that Landlord is not in default or violation of any covenant, provision, obligation, agreement or condition contained in the Lease.

3. Lease Term.

3.1. Extended Lease Term. Pursuant to the Lease, the Lease Term is scheduled to expire on August 31, 2016. Landlord and Tenant hereby agree to extend the Lease Term for a period of five (5) years, from September 1, 2016, until August 31, 2021, on the terms and conditions set forth in the Lease, as hereby amended by this First Amendment, unless sooner terminated as provided in the Lease. The period of time commencing on September 1, 2016, and ending on August 31, 2021, shall be referred to herein as the “Extended Term.”

3.2. No Further Right to Extend Lease Term. Landlord and Tenant acknowledge and agree that the Extended Term provided herein shall be deemed to represent Tenant’s option to extend the Lease Term as provided in Section 2.3 of the Lease, and therefore, effective as of the date of this First Amendment, Section 2.3 of the Lease shall be terminated and of no further force or effect.

4. Rent.

4.1. Base Rent. Prior to September 1, 2016, Tenant shall continue to pay monthly installments of Base Rent for the Premises in accordance with the terms of the Lease. During the Extended Term, Tenant shall pay monthly installments of Base Rent for the Premises as follows, but otherwise in accordance with the terms of the Lease:


Period During Extended Term	Annual Base Rent*		Monthly Installment of Base Rent*		Monthly Rental Rate per Rentable Square Foot*
September 1, 2016 – August 31, 2017	$	525,288.00	$	43,774.00	$	1.72
September 1, 2017 – August 31, 2018	$	543,673.08	$	45,306.09	$	1.78	**
September 1, 2018 – August 31, 2019	$	562,701.60	$	46,891.80	$	1.84	**


Period During Extended Term	Annual Base Rent*		Monthly Installment of Base Rent*		Monthly Rental Rate per Rentable Square Foot*
September 1, 2019 – August 31, 2020	$	582,396.12	$	48,533.01	$	1.91	**
September 1, 2020 – August 31, 2021	$	602,780.04	$	50,231.67	$	1.97	**

The initial Monthly Installment of Base Rent amount was calculated by multiplying the initial Monthly Rental Rate per Rentable Square Foot amount by the number of rentable square feet of space in the Premises, and the initial Annual Base Rent amount was calculated by multiplying the initial Monthly Installment of Base Rent amount by twelve (12). In all subsequent Base Rent payment periods during the Extended Term commencing on September 1, 2017, the calculation of each Monthly Installment of Base Rent amount reflects an annual increase of three and one-half percent (3.5%) and each Annual Base Rent amount was calculated by multiplying the corresponding Monthly Installment of Base Rent amount by twelve (12).

**	The amounts identified in the column entitled “Monthly Rental Rate per Rentable Square Foot” are rounded amounts and are provided for informational purposes only.

4.2. Direct Expenses. Tenant shall continue to be obligated to pay Tenant’s Share of the annual Building Direct Expenses in connection with the Premises which arise or accrue prior to September 1, 2016, in accordance with the terms of the Lease. Effective as of September 1, 2016, and continuing throughout the Extended Term, Tenant shall pay Tenant’s Share of all Building Direct Expenses in connection with the Premises which arise or accrue on or after September 1, 2016, in accordance with the terms of the Lease; provided that for purposes of calculating the amount of Tenant’s Share of such annual Building Direct Expenses, due to the terms of Section 2.1 above, Tenant’s Share shall equal 33.5996%.

5. Utility Billing Information. In the event that the Tenant is permitted to contract directly for the provision of electricity, gas and/or water services to the Premises with the third-party provider thereof (all in Landlord’s sole and absolute discretion), Tenant shall promptly, but in no event more than fifteen (15) days following its receipt of each and every invoice for such items from the applicable provider, provide Landlord with a copy of each such invoice. Tenant acknowledges that pursuant to California Public Resources Code Section 25402.10 and the regulations adopted pursuant thereto (collectively the “Energy Disclosure Requirements”), Landlord may be required to disclose information concerning Tenant’s energy usage at the Building to certain third parties, including, without limitation, prospective purchasers, lenders and tenants of the Building (the “Tenant Energy Use Disclosure”). Tenant hereby (A) consents to all such Tenant Energy Use Disclosures, and (B) acknowledges that Landlord shall not be required to notify Tenant of any Tenant Energy Use Disclosure. Further, Tenant hereby releases Landlord from any and all losses, costs, damages, expenses and liabilities relating to, arising out of and/or resulting from any Tenant Energy Use Disclosure. The terms of this Section 5 shall survive the expiration or earlier termination of the Lease.

6. Green Cleaning/Recycling. To the extent a “green cleaning program” and/or a recycling program is implemented by Landlord in the Building and/or Project (each in Landlord’s sole and absolute discretion), Tenant shall, at Tenant’s sole cost and expense, comply with the provisions of each of the foregoing programs (e.g., Tenant shall separate waste appropriately so that it can be efficiently processed by Landlord’s particular recycling contractors). To the extent Tenant fails to comply with any of Landlord’s recycling programs contemplated by the foregoing, Tenant shall be required to pay any contamination charges related to such non-compliance.

7. Prohibited Persons; Foreign Corrupt Practices Act and Anti-Money Laundering. Neither Tenant nor any of its affiliates, nor any of their respective members, partners or other equity holders, and none of their respective officers, directors or managers is, nor prior to or during the Lease Term, will they become a person or entity with whom U.S. persons or entities are restricted from doing business under (a) the Patriot Act (as defined below), (b) any other requirements contained in the rules and regulations of the Office of Foreign Assets Control, Department of the Treasury (“OFAC”) (including any “blocked” person or entity listed in the Annex to Executive Order Nos. 12947, 13099 and 13224 and any modifications thereto or thereof or any other person or entity named on OFAC’s Specially Designated Blocked Persons List) or (c) any other U.S. statute, Executive Order (including the September 24, 2001, Executive Order Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit or Support Terrorism) or other governmental action (collectively. “Prohibited Persons”). Prior to and during the Lease Term, Tenant, and to Tenant’s knowledge, its employees and any person acting on its behalf have at all times fully complied with, and are currently in full compliance with, the Foreign Corrupt Practices Act of 1977 and any other applicable anti-bribery or anti-corruption laws. Tenant is not entering into this First Amendment, directly or indirectly, in violation of any laws relating to drug trafficking, money laundering or predicate crimes to money laundering. As used herein, “Patriot Act” shall mean the USA Patriot Act of 2001. 107 Public Law 56 (October 26, 2001) and all other statutes, orders, rules and regulations of the U.S. government and its various executive departments, agencies and offices interpreting and implementing the Patriot Act.

8. No Broker. 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 First Amendment, and that they know of no real estate broker or agent who is entitled to a commission in connection with this First Amendment. 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 occurring by, through, or under the indemnifying party. The terms of this Section 8 shall survive the expiration or earlier termination of the term of the Lease, as hereby amended.

9. California Accessibility Disclosure. For purposes of Section 1938 of the California Civil Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges that the Common Areas and the Premises have not undergone inspection by a Certified Access Specialist (CASp).

10. No Further Modification. Except as specifically set forth in this First Amendment, all of the terms and provisions of the Lease shall remain unmodified and in full force and effect.
