Article 2
TERM/PREMISES

The Term of this Lease shall commence on the Commencement Date as set forth in Article 1.A. of the Basic Lease Provisions and shall end on the Expiration Date set forth in Article 1.A. of the Basic Lease Provisions. If Landlord does not deliver possession of the Premises to Tenant on or before the Target Commencement Date (as set forth in Article 1.A, above), Landlord shall not be subject to any liability for its failure to do so, and such failure shall not affect the validity of this Lease nor the obligations of Tenant hereunder; provided however, in the event the Landlord has not delivered the Premises to Tenant within the 9-month period immediately following the Target Commencement Date, Tenant shall have the right to terminate this Lease by providing written notice to Landlord. Landlord and Tenant hereby stipulate that the Premises contains the number of square feet specified in Article 1.B. of the Basic Lease Provisions. Landlord may deliver to Tenant a Commencement Letter in a form substantially similar to that attached hereto as Exhibit “C”, which Tenant shall execute and return to Landlord within ten (10) business days of receipt thereof. Failure of Tenant to timely execute and deliver the Commencement Letter shall constitute acknowledgment by Tenant that the statements included in such notice are true and correct, without exception.

Article 3
RENT

(a) Base Rent. Tenant agrees to pay to Landlord during the Term hereof, at Landlord’s office or to such other person or at such other place as directed from time to time by written notice to Tenant from Landlord, the monthly and annual sums as set forth in Article 1.C. of the Basic Lease Provisions, payable in advance on the first (1st) day of each calendar month, without demand, setoff or deduction, except as may be provided for in this Lease, and in the event this Lease commences or the date of expiration of this Lease occurs other than on the first (1st) day or last day of a calendar month, the rent for such month shall be prorated. Notwithstanding the foregoing, the first full month’s Monthly Base Rent shall be paid to Landlord in accordance with Article 1.I. of the Basic Lease Provisions and, if the Rent Commencement Date is not the first day of a month, Monthly Base Rent for the partial month commencing as of the Rent Commencement Date shall be prorated based upon the actual number of days in such month and shall be due and payable upon the Rent Commencement Date.

(b) Increase in Direct Costs. In addition to Base Rent, Tenant shall pay an additional sum for each Comparison Year equal to the product of the Tenant’s Proportionate Share set forth in Article 1.D. of the Basic Lease Provisions multiplied by the amount of the Direct Costs for both Tax Costs and for Operating Costs (all as hereinafter defined) for such year in excess of such applicable Direct Costs for Taxes and for Operating Costs for each applicable Base Year (as hereinafter defined). In the event either the Premises and/or the Building is expanded or reduced, then Tenant’s Proportionate Share shall be proportionately adjusted, and as to the calendar year in which such change occurs, Tenant’s Proportionate Share for such calendar year shall be determined on the basis of the number of days during that particular calendar year that such Tenant’s Proportionate Share was in effect. In the event this Lease shall terminate on any date other than the last day of a calendar year, the additional sum payable hereunder by Tenant during the calendar year in which this Lease terminates shall be prorated on the basis of the relationship which the number of days which have elapsed from the commencement of said calendar year to and including said date on which this Lease terminates bears to three hundred sixty five (365). Any and all amounts due and payable by Tenant pursuant to this Lease (other than Base Rent) including but not limited to any payments for utilities directly paid by Tenant shall be deemed “Additional Rent” and Landlord shall be entitled to exercise the same rights and remedies upon default in these payments as Landlord is entitled to exercise with respect to defaults in monthly installment of Base Rent payments. Any and all amounts due and payable by Tenant to Landlord shall be in the form of (i) business checks, (ii) wire transfers, (iii) electronic funds transfers, and (iv) automated clearing house payments. Any other forms of payment are not acceptable to Landlord including, without limitation (1) cash or currency, (2) cashier’s checks and money orders, (3) traveler’s checks, (4) payments from credit unions or other non-bank financial institutions, (5) multiple payments for one (1) scheduled payment, and (6) third party checks.

(c) Definitions. As used herein the term “Direct Costs” shall mean the sum of the following:

(i) “Tax Costs”, which shall mean any and all real estate taxes and other similar charges on real property or improvements, assessments, water and sewer charges, and all other charges assessed, reassessed or levied upon the Property and appurtenances thereto and the

-5-

DOCPROPERTY "DocID" \* MERGEFORMAT

parking or other facilities thereof, or the real property thereunder or attributable thereto, or on the rents, issues, profits or income received or derived therefrom which are assessed, reassessed or levied by the United States, the State of California or any local government authority or agency or any political subdivision thereof, and shall include Landlord’s reasonable legal fees, costs and disbursements incurred in connection with proceedings for reduction of Tax Costs or any part thereof; provided, however, if at any time after the date of this Lease the methods of taxation now prevailing shall be altered so that in lieu of or as a supplement to or a substitute for the whole or any part of any Tax Costs, there shall be assessed, reassessed or levied (a) a tax, assessment, reassessment, levy, imposition or charge wholly or partially as a net income, capital or franchise levy or otherwise on the rents, issues, profits or income derived therefrom, or (b) a tax, assessment, reassessment, levy (including but not limited to any municipal, state or federal levy), imposition or charge measured by or based in whole or in part upon the Property and imposed upon Landlord, then except to the extent such items are payable by Tenant under Article 6 below, such taxes, assessments, reassessments or levies or the part thereof so measured or based, shall be deemed to be included in the term “Direct Costs.” For the avoidance of doubt, any income taxes owed by Landlord shall not be included in Tax Costs.

(ii) “Operating Costs”, which shall mean (i) all costs and expenses incurred by Landlord in connection with the maintenance, operation, replacement, and repair of the Building and the Fee Lot, the equipment, the intrabuilding cabling and wiring, adjacent walks and landscaped and common areas and the parking areas and facilities of the Building and (ii) the Building’s share of all costs and expenses incurred by Landlord in connection with the maintenance, operation, replacement, and repair of the exterior common areas of the Property, without limitation, any parking areas owned or leased by Landlord for the use of all tenants equally, and further including, without limitation, supplies, materials, labor and equipment used in or related to the operation and maintenance of the common areas, including parking areas (including, without limitation, all costs of resurfacing and restriping parking areas), signs and directories on the Building and/or the Property, landscaping (including, without limitation, maintenance contracts and fees payable to landscaping consultants), amenities, sprinkler systems, sidewalks, walkways, driveways, curbs, lighting systems, cafeteria operating costs, and security services, if any, provided by Landlord for the common areas, and any charges, assessments, costs or fees levied by any association or entity of which the Park or any part thereof is a member or to which the Park or any part thereof is subject. Operating Costs shall include but not be limited to, management fees and expenses, salaries, wages, fringe benefits, and employment taxes for all persons who perform duties connected with the operation, maintenance and repair of the Building or the Park (including, but not limited to, the parking facilities), its equipment, the intrabuilding cabling and wiring and the adjacent walks and landscaped areas, including janitorial, gardening, security, the cost of parking area operation, repair, restoration, and maintenance, operating engineer, elevator, painting, plumbing, electrical, carpentry, existing generator, heating, ventilation, air conditioning and window washing; hired services; a reasonable allowance for depreciation of the cost of acquiring or the rental expense of personal property used in the maintenance, operation and repair of the Property; accountant’s fees incurred in the preparation of rent adjustment statements; legal fees; real estate tax consulting fees; personal property taxes on property used in the maintenance and operation of the Building and the Property; payments under any easement, license, operating agreement, declaration, restrictive covenant, or instrument pertaining to the sharing of costs, including, without limitation, fees, costs, expenses or dues payable pursuant to the terms of the Declaration of Easements, the Park Covenants, the Grant of

(iii) Landlord shall have the right, from time to time, to equitably allocate some or all of the Operating Costs among different portions or occupants of the Building (the “Cost Pools”), in Landlord’s discretion, subject to providing sufficient rationale and supporting calculations upon request. Such Cost Pools may include, but shall not be limited to, the office space tenants of the Building, laboratory space tenants and retail space tenants of the Building and Tenant’s Proportionate Share of Operating Expenses for any costs included in a Cost Pool shall be calculated on the basis of the ratio of the rentable square footage of the Premises to the rentable square footage of the portions of the Building included in such Cost Pool from time to time.

(iv) “Base Year” shall mean (A) for Tax Costs, the actual Tax Costs for the 2026 Fiscal Year, (i.e. July 1, 2025 through June 30, 2026) and (B) for Operating Costs the actual Operating Costs for calendar year 2025.

(v) “Comparison Year” shall mean each applicable calendar year (or applicable fiscal year, for Tax Costs) during the Term from and after the Base Year.

(d) Determination of Payment.

(i) Landlord shall give Tenant a yearly expense estimate statement (the “Estimate Statement”) which shall set forth Landlord’s reasonable estimate (the “Estimate”) of what the total amount of Direct Costs for the then-current calendar year shall be and Tenant’s Proportionate Share thereof and Tenant shall pay monthly, with each monthly installment of Base Rent, an amount equal to one-twelfth (1/12) of the total Estimate set forth in the Estimate Statement delivered by Landlord to Tenant.

(ii) In addition, Landlord shall give to Tenant as soon as reasonably practicable following the end of each calendar year, a statement (the “Statement”) which shall state the Direct Costs incurred or accrued for such preceding calendar year, and which shall indicate the amount of Tenant’s Proportionate Share thereof. Upon receipt of the Statement for each calendar year during the Term, Tenant shall pay, with its next monthly installment of Base Rent due, the full amount of Tenant’s Proportionate Share of Direct Costs for such prior calendar year, less the amounts, if any, paid during such calendar year on an estimated basis. If, however, the Statement indicates that amounts paid by Tenant on an estimated basis are greater than the actual amount of Tenant’s Proportionate Share of Direct Costs specified on the Statement, such overpayment shall be credited against Tenant’s next installments of estimated payments. The failure of Landlord to timely furnish the Statement for any calendar year shall not prejudice Landlord from enforcing its rights under this Article 3, once such Statement has been delivered. Even though the Term has expired and Tenant has vacated the Premises, when the final determination is made of Tenant’s Proportionate Share of the Direct Costs for the calendar year in which this Lease terminates, Tenant shall promptly pay to Landlord an amount as calculated pursuant to the provisions of this Section

-9-

DOCPROPERTY "DocID" \* MERGEFORMAT

3(d). The provisions of this Section 3(d)(ii) shall survive the expiration or earlier termination of the Term.

(iii) During the 90-day period after receipt of any Statement (the “Review Period”), Tenant may inspect and audit Landlord’s records relevant to the cost and expense items reflected in such Statement (a “Tenant Audit”) at the offices of Landlord’s management company at a reasonable time mutually agreeable to Landlord and Tenant during Landlord’s usual business hours, provided that Tenant shall have one (1) such right per year. Each Statement shall be conclusive and binding upon Tenant unless, during the applicable Review Period, Tenant shall notify Landlord that it disputes the correctness of such Statement, specifying the respects in which the Statement is claimed to be incorrect. The Tenant Audit shall be conducted by Tenant at its sole cost and expense unless the results of such Tenant Audit show that the Statement overstated the amount of Direct Costs owed by Tenant for the relevant billing period by more than five percent (5%) in which case Landlord shall be responsible for payment of such reasonable out-of-pocket costs and expenses.

(iv) If the Fee Lot is a part of a multi-building development, those Direct Costs attributable to such development as a whole (and not attributable solely to any individual building therein) shall be allocated by Landlord to the Property and to the other buildings within such development on an equitable basis, with sufficient rationale and supporting calculations to be provided upon request.

Article 4
LETTER OF CREDIT

(a) Simultaneously with the execution and delivery of this Lease by Tenant, Tenant shall deliver to Landlord, and Tenant shall maintain in effect at all times during the Term (as the same may be extended), as security for the full and faithful performance and observance by Tenant of Tenant’s covenants and obligations under this Lease, an unconditional, irrevocable, standby letter of credit in the amount set forth in the Basic Lease Provisions, and substantially in the form annexed hereto as Exhibit “F” attached hereto and otherwise reasonably satisfactory to Landlord and issued by a banking corporation reasonably satisfactory to Landlord. Such letter of credit shall have an expiration date no earlier than the first anniversary of the date of issuance thereof and shall be automatically renewed from year to year unless terminated by the issuer thereof by notice to Landlord given not less than thirty (30) days prior to the expiration thereof. Tenant shall, throughout the Term of this Lease, deliver to Landlord, in the event of the termination of any such letter of credit, replacement letters of credit in lieu thereof (each such letter of credit and such extensions or replacements thereof, as the case may be, is hereinafter referred to as a “Letter of Credit”) no later than thirty (30) days prior to the expiration date of the preceding Letter of Credit. The term of each such Letter of Credit shall be not less than one year and shall be automatically renewable from year to year as aforesaid. Notwithstanding the foregoing, if Landlord shall elect, in its sole discretion, to accept a Letter of Credit which is subject to a final expiration date, Tenant shall deliver a replacement of or amendment to such Letter of Credit no later than thirty (30) days prior to such final expiration date, and the final Letter of Credit delivered to Landlord pursuant to this Article 4 shall have a final expiration date occurring not earlier than sixty (60) days following the expiration date of this Lease. If Tenant shall fail to obtain any replacement of or amendment to a Letter of Credit within any of the applicable time limits set forth in this Section 4(a), such

-10-

DOCPROPERTY "DocID" \* MERGEFORMAT

failure shall constitute an immediate Event Default of Tenant under this Lease without any additional notice or cure period under Article 19 of this Lease applicable thereto.

(b) Provided an Event of Default is not then in existence, upon the expiration of the fifth (5th) Lease Year, upon the written request of Tenant, the Letter of Credit shall be reduced to $569,952.48. The reduction of the Letter of Credit may be accomplished either by amendment of the existing Letter of Credit held by Landlord or by the replacement of the then-existing Letter of Credit with a new Letter of Credit reflecting the lower amount. Landlord agrees to promptly cooperate with the reduction of the Letter of Credit amount as set forth herein.

(c) In the event Tenant defaults in respect of the full and prompt payment and performance of any of the terms, provisions, covenants and conditions of this Lease beyond notice (the delivery of which shall not be required for purposes of this Section 4(b) if Landlord is prevented or prohibited from delivering the same under applicable law, including, but not limited to, all applicable bankruptcy and insolvency law) and the expiration of any applicable cure periods (except that no notice and cure period shall be required for purposes of this Section 4(b) with respect to any default by Tenant hereunder if, at the time of such default, any of the events set forth in Section 19(e) shall have occurred with or without the acquiescence of Tenant), including, but not limited to, the payment of Base Rent and Additional Rent, Landlord may, at its election, (but shall not be obligated to) draw down the entire Letter of Credit or any portion thereof and use, apply or retain the whole or any part of the security represented by the Letter of Credit to the extent required for the payment of: (i) Base Rent, Additional Rent or any other sum as to which Tenant is in default, (ii) any sum which Landlord may expend or may be required to expend by reason of Tenant’s default in respect of any of the terms, provisions, covenants, and conditions of this Lease, including but not limited to, any reletting costs or expenses (including, without limitation, any free rent, tenant improvement allowance, leasing commissions, attorneys’ fees, costs and expenses, and other fees, costs and expenses relating to the reletting of all or any portion of the Premises), (iii) any damages or deficiency in the reletting of the Premises, whether such damages or deficiency accrued before or after summary proceedings or other re-entry by Landlord, or (iv) any damages awarded to Landlord in accordance with the terms and conditions of Article 19 hereof, it being understood that any use of the whole or any part of the security represented by the Letter of Credit shall not constitute a bar or defense to any of Landlord’s other remedies under this Lease or any Law, including but not limited to Landlord’s right to assert a claim against Tenant under 11 U.S.C. §502(b)(6) or any other provision of Title 11 of the United States Code. To ensure that Landlord may utilize the security represented by the Letter of Credit in the manner, for the purpose, and to the extent provided in this Section 4(b), each Letter of Credit shall provide that the full amount or any portion thereof may be drawn down by Landlord upon the presentation to the issuing bank (or the advising bank, if applicable) of Landlord’s draft drawn on the issuing bank without accompanying memoranda or statement of beneficiary. In no event shall the Letter of Credit require Landlord to submit evidence to the issuing (or advising) bank of the truth or accuracy of any such written statement and in no event shall the issuing bank or Tenant have the right to dispute the truth or accuracy of any such statement nor shall the issuing (or advising) bank have the right to review the applicable provisions of the Lease. In no event and under no circumstance shall the draw down on or use of any amounts under the Letter of Credit constitute a basis or defense to the exercise of any other of Landlord’s rights and remedies under this Lease or under any Law, including, but not limited to, Landlord’s right to assert a claim against Tenant under 11 U.S.C. §502(b)(6) or any other provision of Title 11 of the United States Code.

(d) In the event Tenant defaults in respect of any of the terms, provisions, covenants or conditions of this Lease beyond notice (the delivery of which shall not be required for purposes of this Article 4 if Landlord is prevented or prohibited from delivering the same under applicable law, including, but not limited to, all applicable bankruptcy and insolvency law) and the expiration of any applicable cure periods (except no notice and cure period shall be required for purposes of this Article 4 with respect to any default by Tenant hereunder if, at the time of such default, any of the events set forth in Section 19(e) shall have occurred with or without the acquiescence of Tenant) and Landlord utilizes all or any part of the security represented by the Letter of Credit but does not terminate this Lease as provided in Article 20 hereof, Landlord may, in addition to exercising its rights as provided in paragraph (b) hereof, retain the unapplied and unused balance of the portion of the Letter of Credit drawn down by Landlord (herein called the “Cash Security”) as security for the faithful performance and observance by Tenant thereafter of the terms, provisions, and conditions of this Lease, and may use, apply, or retain the whole or any part of said Cash Security to the extent required for payment of Base Rent, Additional Rent or any other sum as to which Tenant is in default (beyond applicable notice and cure periods) or for any sum which Landlord may expend or be required to expend by reason of Tenant’s default in respect of any of the terms, covenants, and conditions of this Lease. In the event Landlord uses, applies or retains any portion or all of the security represented by the Letter of Credit, Tenant shall forthwith restore the amount so used, applied or retained (at Landlord’s option, either by the deposit with Landlord of cash or the provision of a replacement Letter of Credit) so that at all times the amount of the security represented by the Letter of Credit and the Cash Security (if any) shall be not less than the security required by this Lease, failing which Tenant shall be in default of its obligations under this Article 4 and Landlord shall have the same rights and remedies as for the non-payment of Base Rent beyond the applicable grace period.

(e) If Tenant shall fully and faithfully comply with all of Tenant’s covenants and obligations under this Lease, the Letter of Credit and the Cash Security (if any) shall be returned to Tenant within sixty (60) days after the expiration or termination of this Lease and after delivery to Landlord of entire possession of the Premises; provided, however, that in no event shall any such return be construed as an admission by Landlord that Tenant has performed all of its obligations hereunder. In the event of any sale, transfer or leasing of Landlord’s interest in the Building whether or not in connection with a sale, transfer or leasing of the Land to a vendee, transferee or lessee, Landlord shall have the right to transfer the Letter of Credit and the Cash Security (if any) to the vendee, transferee or lessee or, in the alternative, to require Tenant to deliver a replacement Letter of Credit or appropriate amendment to the Letter of Credit naming the new landlord as beneficiary, and, upon delivery by Tenant of a replacement Letter of Credit, if applicable, Landlord shall return the existing Letter of Credit to Tenant or the issuer. Tenant shall be responsible to pay any transfer commission and other costs charged by the issuing bank in connection with any such transfer of the Letter of Credit. Upon such transfer or return of the Letter of Credit and the Cash Security (if any), Landlord shall thereupon be released by Tenant from all liability for the return thereof, and Tenant shall look solely to the new landlord for the return of the same. The provisions of the preceding sentence shall apply to every subsequent sale, transfer or leasing of the Building, and any successor of Landlord may, upon a sale, transfer, leasing or other cessation of the interest of such successors in the Building, whether in whole or in part, transfer the Letter of Credit and the Cash Security (if any) to any vendee, transferee or lessee of the Building (or require Tenant to deliver a replacement Letter of Credit as hereinabove set forth) and shall thereupon be relieved of all liability with respect thereto. Except in connection with a

-12-

permitted assignment of this Lease, Tenant shall not assign or encumber or attempt to assign or encumber the security represented by the Letter of Credit, and neither Landlord nor its successors or assigns shall be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance. In any event, in the absence of evidence satisfactory to Landlord of an assignment of the right to receive the security represented by the Letter of Credit, Landlord may return the Letter of Credit to the original Tenant regardless of one or more assignments of this Lease.

(f) Neither the Letter of Credit, any proceeds therefrom or the Cash Security, if any, shall be deemed an advance rent deposit or an advance payment of any other kind, or a measure or limitation of Landlord’s damages or constitute a bar or defense to any of the Landlord’s other remedies under this Lease or at law or in equity upon Tenant’s default.

(g) In addition to and without limitation of Landlord’s other rights under this Article 4, if at any time during the Term of the Lease (as the same may be extended), Landlord reasonably determines that the financial condition of the issuer of the then current Letter of Credit is such that Landlord’s ability to draw upon the Letter of Credit is, or in the future may be, impaired, restricted, refused or otherwise adversely affected, then Landlord shall have the right, by giving Tenant written notice of such requirement, to (i) immediately draw upon the Letter of Credit and use, apply and retain the same as Cash Security hereunder, and (ii) require that Tenant obtain, within twenty (20) business days, from a new issuer a replacement Letter of Credit, which issuer and replacement Letter of Credit shall both comply in all respects with the requirements of this Article 4. In the event that Tenant shall not have delivered to Landlord a replacement Letter of Credit complying with all of the requirements of this Article 4 within twenty (20) business days after Tenant’s receipt of such notice, Landlord shall have the right (but not the obligation), to exercise Landlord’s rights under Section 4(b) above with respect to such failure and to exercise any other rights and remedies under the Lease, at law or in equity with respect to such Event of Default of Tenant. Upon delivery to Landlord of any such replacement Letter of Credit within the time period described in the preceding sentence, Landlord shall return to Tenant the proceeds of the Letter of Credit which had been drawn by Landlord pursuant to the preceding sentence (or any balance thereof to which Tenant is entitled).

Article 5
HOLDING OVER

Should Tenant (or any subtenant, assignee or other party occupying the Premises by, through, under, or with the permission of Tenant), without Landlord’s written consent, hold over after termination of this Lease, Tenant shall, at Landlord’s option, become either a tenant at sufferance or a month-to-month tenant upon each and all of the terms herein provided as may be applicable to such a tenancy and any such holding over shall not constitute an extension of this Lease. During such holding over, Tenant shall pay in advance, monthly, Base Rent at a rate equal to one hundred fifty percent (150%) of the Base Rent payable by Tenant during the final month of the term of this Lease, for the first two (2) months, and thereafter two hundred percent (200%) of the Base Rent payable by Tenant during the final month of the term of this Lease, in addition to, and not in lieu of, all other payments required to be made by Tenant hereunder including but not limited to Tenant’s Proportionate Share of any Direct Costs. Nothing contained in this Article 5 shall be construed as consent by Landlord to any holding over of the Premises by Tenant, and

-13-

DOCPROPERTY "DocID" \* MERGEFORMAT

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 earlier termination of the Term. If Tenant fails to surrender the Premises within the first fifteen (15) days immediately following the expiration or termination of this Lease, Tenant agrees to indemnify, defend and hold Landlord harmless from and against all costs, loss, expense or liability, including without limitation, claims made by any succeeding tenant and real estate brokers claims and attorney’s fees and costs.

Article 6
OTHER TAXES

Tenant shall pay, prior to delinquency, all taxes assessed against or levied upon trade fixtures, furnishings, equipment and all other personal property of Tenant located in the Premises. In the event any or all of Tenant’s trade fixtures, furnishings, equipment and other personal property shall be assessed and taxed with property of Landlord, or if the cost or value of any leasehold improvements in the Premises exceeds the cost or value of a Building-standard buildout as reasonably determined by Landlord and to the extent, as a direct result, real property taxes for the Fee Lot are increased, Tenant shall pay to Landlord, with the next monthly installment of Base Rent following delivery to Tenant by Landlord of a written statement setting forth such amount, the amount of such taxes applicable to Tenant’s property or above-standard improvements. Tenant shall assume and pay to Landlord at the time Base Rent next becomes due (or if assessed after the expiration of the Term, then within ten (10) business days), any excise, sales, use, rent, occupancy, garage, parking, gross receipts or other taxes (other than net income taxes) which may be assessed against or levied upon Landlord on account of the letting of the Premises to Tenant or the payment of Base Rent or any other sums due or payable hereunder from Tenant, and which Landlord may be required to pay or collect under any law now in effect or hereafter enacted during the Term of this Lease. In addition to Tenant’s obligation pursuant to the immediately preceding sentence, Tenant shall pay directly to the party or entity entitled thereto, or otherwise timely contest, all business license fees, gross receipts taxes and similar taxes and impositions which may from time to time be assessed against or levied upon Tenant, as and when the same become due and before delinquency. Notwithstanding anything to the contrary contained herein, any sums payable by Tenant under this Article 6 shall not be included in the computation of “Tax Costs.”

Article 7
USE

(a) Use. Tenant shall use and occupy the Premises only for the use set forth in Article 1.F. of the Basic Lease Provisions and shall not use or occupy the Premises or permit the same to be used or occupied for any other purpose without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed, provided Tenant is in compliance with the terms of this Lease and any applicable laws or other rules and regulations, and Tenant agrees that it will use the Premises in such a manner so as not to interfere with or infringe upon the rights of other tenants or occupants in the Building. Tenant shall, at its sole cost and expense, promptly comply with all laws, statutes, ordinances, governmental regulations or requirements (including, without limitation all Hazardous Material Laws as defined in Section 28(e) below and any laws which may require Tenant to temporarily cease operations or prohibit or reduce Tenant’s use of the Premises) now in force or which may hereafter be in force relating to or affecting (i) the condition, use or occupancy of the Premises or the Building, and (ii)

-14-

DOCPROPERTY "DocID" \* MERGEFORMAT

improvements, trade fixtures and equipment installed or constructed in the Premises by or for the benefit of Tenant. Tenant hereby agrees and acknowledges that the manufacture, cultivation, sale, use, trade or possession of any drugs or other substance in violation of the laws of the United States of America in the Premises shall be a material breach of this Lease (without any applicable notice and cure period) except where Tenant has obtained an applicable license permitting such use by a relevant governmental authority. Tenant shall comply with, and Tenant’s rights and obligations under this Lease and Tenant’s use of the Premises shall be subject and subordinate to, all recorded easements, covenants, conditions, restrictions and other Underlying Documents now or hereafter affecting the Property. Tenant shall not do or permit to be done anything which would invalidate or increase the cost of any insurance policy covering the Property and/or the property located therein and Tenant shall comply with all rules, orders, regulations and requirements of any organization which sets out standards, requirements or recommendations commonly referred to by major fire insurance underwriters, and Tenant shall promptly upon demand reimburse Landlord for any additional premium charges for any such insurance policy assessed or increased by reason of Tenant’s use of the Premises or failure to comply with the provisions of this Article 7. If applicable, Tenant shall comply with Landlord’s reasonable sustainability practices applicable to the Property, if any, and shall not permit any use of the Premises which may affect the continued certification of the Property issued pursuant to the LEED rating system (or other applicable certification standard).

(b) Odors and Ventilation. Tenant shall not cause or permit (or conduct any activities that would cause) any release of any offensive odors or fumes of any kind from the Premises that are incompatible with the current and permitted uses of the Building and the Premises. If Landlord at any time determines that any existing ventilation system is inadequate, or if no ventilation system exists, Tenant shall in compliance with applicable laws vent all impermissible fumes and odors from the Premises (and remove odors from Tenant’s exhaust stream) as Landlord requires, at Tenant’s sole cost and expense. The placement and configuration of all ventilation exhaust pipes, louvers and other equipment shall be subject to Landlord’s prior written approval, which shall not be unreasonably withheld, conditioned or delayed. Tenant acknowledges Landlord’s legitimate desire to maintain the Building (indoor and outdoor areas) free of offensive odors, and Landlord may require Tenant to abate and remove all offensive odors in a manner that goes beyond the requirements of applicable laws. Tenant shall, at Tenant’s sole cost and expense, provide odor eliminators and other devices (such as filters, air cleaners, scrubbers and whatever other equipment may in Landlord’s judgment be necessary or appropriate from time to time) as required to remove, eliminate and abate any offensive odors, fumes or other substances in Tenant’s exhaust stream that are incompatible with the current and permitted uses of the Building and the Premises. If Tenant fails to install commence the installation of satisfactory odor control equipment within thirty (30) days after Landlord’s demand made at any time, then Landlord may, without limiting Landlord’s other rights and remedies, require Tenant to cease and suspend any operations in the Premises that, in Landlord’s reasonable determination, cause offensive odors, fumes or exhaust or, Landlord may take such measures as Landlord reasonably deems necessary to abate such offensive odors, fumes or exhaust, and Tenant shall pay all costs incurred by Landlord in connection with such remedial measures, including Landlord’s costs related to any third party complaints, with the next monthly installment of Base Rent as Additional Rent. For the purpose of the immediately foregoing sentence, Landlord’s determination shall be “reasonable” in the event, but without limitation, Landlord has received any written complaint regarding such offensive odors, fumes or exhaust. If such issues persist, Landlord may, in its reasonable discretion but at Tenant’s sole cost and

-15-

expense, engage a third party company to monitor, report and remedy any issues related to odors, fumes or exhaust.

Article 8
CONDITION OF PREMISES

Tenant hereby agrees that except as provided in the Tenant Work Letter attached hereto as Exhibit “D” and made a part hereof the Premises shall be taken “as is”, “with all faults”, “without any representations or warranties”, and Tenant hereby agrees and warrants that it has investigated and inspected the condition of the Premises and the suitability of same for Tenant’s purposes, and Tenant does hereby waive and disclaim any objection to, cause of action based upon, or claim that its obligations hereunder should be reduced or limited because of the condition of the Premises or the Building or the suitability of same for Tenant’s purposes. Tenant acknowledges that neither Landlord nor any agent nor any employee of Landlord has made any representations or warranty with respect to the Premises or the Building or with respect to the suitability of either for the conduct of Tenant’s business and Tenant expressly warrants and represents that Tenant has relied solely on its own investigation and inspection of the Premises and the Building in its decision to enter into this Lease and let the Premises in the above-described condition. Nothing contained herein is intended to, nor shall, obligate Landlord to implement sustainability practices for the Property or to seek certification under, or make modifications in order to obtain, a certification from LEED or any other comparable certification. The Premises shall be initially improved as provided in, and subject to, the Tenant Work Letter attached hereto as Exhibit “D” and made a part hereof. The existing leasehold improvements in the Premises as of the date of this Lease, together with the Tenant Improvements (as defined in the Tenant Work Letter) may be collectively referred to herein as the “Improvements.” Notwithstanding the foregoing, Landlord shall tender the Premises to Tenant in broom clean condition, free of personal property, other occupants or any Hazardous Materials. Unless Tenant provides written notice to Landlord identifying unsatisfactory conditions in the Premises and/or the Building within the 30-day period immediately following the Commencement Date, Tenant shall be conclusively deemed to have accepted the Premises in satisfactory condition.

(i) Tenant shall be responsible, at Tenant’s sole cost and expense, for repair and maintenance of any HVAC Systems (as hereinafter defined), including any Supplemental Units (as hereinafter defined), exclusively serving the Premises and in connection therewith, Tenant shall retain a service and maintenance contract for such HVAC Systems with a contractor designated by Landlord to ensure regular maintenance which shall include, without limitation, (i) regular inspection, cleaning and testing of the HVAC Systems, (ii) any servicing, maintenance, repairs and replacements of filters, belts or other items determined to be necessary or appropriate as a result of such inspections and tests, or by the manufacturers’ warranty, service manual or technical bulletins, or otherwise required to ensure proper and efficient operation, including emergency work, (iii) all other work as shall be reasonably required by Landlord or Landlord’s insurance carriers, (iv) a detailed record of all services performed (Tenant shall provide Landlord with a copy of such annual reports promptly upon Landlord’s written request), and (v) an annual service report at the end of each calendar year. In the event of any abandonment of the Premises by Tenant, Tenant shall continue to be responsible for the repair and maintenance of any HVAC Systems as set forth above. Notwithstanding the preceding provisions of this paragraph, Landlord may elect at any time upon written notice to Tenant to perform the maintenance and repairs of such HVAC Systems for the account of Tenant. In such event, Tenant shall pay the cost of the service and maintenance contract for such HVAC Systems serving the Premises, as well as for costs of repair and maintenance thereof as necessary in the reasonable judgment of Landlord, as Additional Rent, within ten (10) days of receipt of billings therefor from Landlord. Alternatively, Landlord may, at its option, elect to have such HVAC Systems serving the Premises maintained, repaired and replaced in common with other equipment in the Building. In such event, within ten (10) days after receipt of billings therefor and as Additional Rent, Tenant shall pay its pro rata share of such maintenance costs, which share shall be established in an equitable manner by Landlord based upon the relative tonnage provided to the Premises, compared to the total tonnage under contract, or some other reasonable means of allocation as selected by Landlord. Landlord’s good faith judgment as to the allocation of the charges described in this paragraph shall be conclusive. Included in the charges to be allocated to Tenant shall be, without limitation, the maintenance contract for such HVAC Systems, and any repairs and replacements not covered by the maintenance contract or any warranty or insurance.

(ii) All damage or injury to the Premises or the Building resulting from the negligence or willful misconduct of Tenant, its employees, agents or visitors, guests, invitees or licensees or by the use of the Premises, shall be promptly repaired by Tenant at its sole cost and expense, to the satisfaction of Landlord; provided, however, that for repairs that may impact the mechanical, electrical, plumbing, heating, ventilation or air-conditioning systems of the Building, Landlord shall have the right (but not the obligation) to select the contractor and oversee all such repairs. Landlord may make any repairs which are not promptly commenced by Tenant after Tenant’s receipt of written notice and the reasonable opportunity of Tenant to make said repair within ten (10) business days from receipt of said written notice (except in the case of an emergency), and charge Tenant for the cost thereof, which cost shall be paid by Tenant with the next monthly installment of Base Rent following receipt of an invoice from Landlord. Tenant shall be responsible for the design and function of all non-standard improvements of the Premises, whether or not installed by Landlord at Tenant’s request.

Any Alterations approved by Landlord must be performed in accordance with the terms hereof, using only contractors or mechanics approved by Landlord in writing and upon the approval by Landlord in writing of fully detailed and dimensioned plans and specifications pertaining to the Alterations in question, to be prepared and submitted by Tenant at its sole cost and expense. Tenant shall at its sole cost and expense obtain all necessary approvals and permits pertaining to any Alterations approved by Landlord. Tenant shall cause all Alterations to be performed in a good and workmanlike manner, in conformance with all applicable federal, state, county and municipal laws, rules and regulations, pursuant to a valid building permit, and in conformance with Landlord’s construction rules and regulations. If Landlord, in approving any Alterations, specifies a commencement date therefor, Tenant shall not commence any work with respect to such Alterations prior to such date. Tenant hereby agrees to indemnify, defend, and hold Landlord free and harmless from all liens and claims of lien, and all other liability, claims and demands arising out of any work done or material supplied to the Premises by or at the request of Tenant in connection with any Alterations. Notwithstanding anything to the contrary above, Tenant shall have the right, without obtaining the prior approval of Landlord, but upon written notice to Landlord given at least thirty (30) days prior to the commencement of any work (which notice shall specify the nature of the work in reasonable detail), to make Alterations to the Premises which: (i) are solely within the interior of the Premises, and do not affect the exterior of the Premises and/or the Building (including signs on windows); and (ii) do not adversely affect the roof, any structural element of the Building, the mechanical, electrical, plumbing, heating, ventilating, air-conditioning and fire protection systems of the Building; and (iii) in each instance (and in the aggregate for any twelve (12) month period) cost less than Fifty Thousand Dollars ($50,000.00); and (iv) in all respects, comply with any applicable laws or other legal requirements.

In addition, Landlord may, in its discretion, require Tenant to obtain a bond or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien free completion of such Alterations.

(e) Costs and Fees; Removal. If permitted Alterations are made, they shall be made at Tenant’s sole cost and expense and any permanent Alterations shall be and become the property of Landlord at the expiration of the Lease, except that Landlord may, by reasonable written notice to Tenant given prior to the end of the Term, require Tenant, at Tenant’s expense, to remove any or all fixed improvements, partitions, counters, railings, systems, Improvements and other Alterations from the Premises, and to repair any damage to the Premises and the Building caused by such removal.

Any and all costs attributable to or related to the applicable building codes of the city in which the Building is located (or any other authority having jurisdiction over the Building) arising from Tenant’s plans, specifications, improvements, Alterations or otherwise shall be paid by Tenant at its sole cost and expense. With regard to repairs, Alterations or any other work arising

(iv) Elevator service in the common areas of the Building and water for lavatory and landscaping purposes in the common area and in the Premises in such reasonable quantities as in the judgment of Landlord is reasonably necessary for general office use. If Landlord determines that Tenant requires, uses or consumes water for other purposes, Landlord may install a water meter or submeter, at Tenant’s sole cost and expense, and thereby measure Tenant’s water consumption for all purposes and Tenant shall make payment directly to the entity providing such water if the same is separately metered or Tenant shall reimburse Landlord, promptly upon demand therefor by Landlord, as Additional Rent for the cost of such water if the same is submetered at the rates charged for such service by the city in which the Building is located or the local public water district, as the case may be, furnishing the same, plus any additional expense incurred by Landlord in keeping account of the water so consumed.

Except as specifically provided in this Article 11, Tenant agrees to pay for all utilities and other services utilized by Tenant and any additional building services furnished to Tenant which are not uniformly furnished to all tenants of the Building, at the rate generally charged by Landlord to tenants of the Building for such utilities or services.

(b) Excess Usage. Tenant will not, without the prior written consent of Landlord, use any apparatus or device in the Premises which will in any way increase the amount of water usually furnished or supplied for use of the Premises as general office space; nor connect any apparatus, machine or device with water pipes, for the purpose of using water.

(c) HVAC Balance. If any lights, machines or equipment (including but not limited to computers and computer systems and appurtenances and any lab equipment or systems) are used by Tenant in the Premises which materially affect the temperature otherwise maintained by the HVAC system, or generate substantially more heat in the Premises than would be generated by the building standard lights and usual office equipment, Landlord shall have the right to install any

machinery and equipment which Landlord reasonably deems necessary to restore temperature balance, including but not limited to modifications to the standard air conditioning equipment, and the cost thereof, including the cost of installation and any additional cost of operation and maintenance occasioned thereby, shall be paid by Tenant to Landlord, upon demand by Landlord.

(d) Telecommunications. Upon request from Tenant from time to time, Landlord will provide Tenant with a listing of telecommunications and media service providers serving the Building, and Tenant shall have the right to contract directly with the providers of its choice. If Tenant wishes to contract with or obtain service from any provider which does not currently serve the Building or wishes to obtain from an existing carrier services which will require the installation of additional equipment, such provider must, prior to providing service, enter into a written agreement with Landlord setting forth the terms and conditions of the access to be granted to such provider. In considering the installation of any new or additional telecommunications cabling or equipment at the Building, Landlord will consider all relevant factors in a reasonable and non- discriminatory manner, including, without limitation, the existing availability of services at the Building, the impact of the proposed installations upon the Building and its operations and the available space and capacity for the proposed installations. Landlord may also consider whether the proposed service may result in interference with or interruption of other services at the Building or the business operations of other tenants or occupants of the Building. In no event shall Landlord be obligated to incur any costs or liabilities in connection with the installation or delivery of telecommunication services or facilities at the Building. All such installations shall be subject to Landlord’s prior approval and shall be performed in accordance with the terms of Article 9. If Landlord approves the proposed installations in accordance with the foregoing, Landlord will deliver its standard form agreement upon request and will use commercially reasonable efforts to promptly enter into an agreement on reasonable and non-discriminatory terms with a qualified, licensed and reputable carrier confirming the terms of installation and operation of telecommunications equipment consistent with the foregoing.

(e) Sole Electrical Representative. Tenant agrees that Landlord shall be the sole and exclusive representative with respect to, and shall maintain exclusive control over, the reception, utilization and distribution of electrical power, regardless of point or means of origin, use or generation.

Tenant shall, at least twenty (20) days prior to the expiration of such policies, furnish Landlord with a certificate of insurance. Tenant agrees that if Tenant does not take out and maintain such insurance or furnish Landlord with renewals or binders in a timely manner, Landlord may (but shall not be required to) procure said insurance on Tenant’s behalf and charge Tenant the cost thereof, which amount shall be payable by Tenant upon demand with interest (at the rate set forth in Section 20(e) below) from the date such sums are expended.

Article 15
ASSIGNMENT AND SUBLETTING

Tenant shall have no power to, either voluntarily, involuntarily, by operation of law or otherwise, sell, assign, transfer or hypothecate this Lease, or sublet the Premises or any part thereof, or permit the Premises or any part thereof to be used or occupied by anyone other than Tenant or Tenant’s employees without the prior written consent of Landlord, which consent shall not be unreasonably withheld. If Tenant is a corporation, unincorporated association, partnership or limited liability company, the sale, assignment, transfer or hypothecation of any class of stock or other ownership interest in such corporation, association, partnership or limited liability company in excess of thirty-five percent (35%) in the aggregate other than on a public stock exchange shall not be deemed a “Transfer” within the meaning and provisions of this Article 15, provided that any such transferee shall have equal creditworthiness to the current shareholders of Tenant and provided that in no event shall such transfer result in a change in use of the Premises from the use contemplated herein. Notwithstanding the foregoing, Tenant shall have the right to obtain financing from institutional investors (including venture capital funding and corporate partners) or undergo a public offering which results in a change in control of Tenant without such change of control requiring Landlord’s consent under this Article 15, provided that (i) Tenant notifies Landlord in writing of the financing at least thirty (30) days prior to the anticipated closing of the financing or other transaction, and (ii) provided that in no event shall such financing result in a change in use of the Premises from the use contemplated herein. Tenant may transfer its interest pursuant to this Lease only upon the following express conditions, which conditions are agreed by Landlord and Tenant to be reasonable:

(a) That the proposed Transferee (as hereafter defined) shall be subject to the prior written consent of Landlord, which consent will not be unreasonably withheld but, without limiting the generality of the foregoing, it shall be reasonable for Landlord to deny such consent if:

(i) The use to be made of the Premises by the proposed Transferee is (A) a use which would be prohibited by any other portion of this Lease (including but not limited to any Rules and Regulations then in effect), or (B) a use other than the Permitted Use;

(ii) The financial responsibility of the proposed Transferee is not reasonably satisfactory to Landlord;

(d) A copy of said assignment and assumption agreement or other Transfer on a form reasonably approved by Landlord, shall be delivered to Landlord within five (5) days after the execution thereof. It shall be a condition to Landlord’s consent to any subleasing, assignment or other transfer of part or all of Tenant’s interest in the Premises (“Transfer”) that (i) upon Landlord’s consent to any Transfer, Tenant shall pay and continue to pay Landlord fifty percent (50%) of any “Transfer Premium” (defined below), received by Tenant from the transferee; (ii) any sublessee of part or all of Tenant’s interest in the Premises shall agree that in the event Landlord gives such sublessee notice that Tenant is in default under this Lease, such sublessee shall thereafter make all sublease or other payments directly to Landlord; (iii) any such Transfer and consent shall be effected on reasonable forms supplied by Landlord and/or its legal counsel; (iv) Landlord may require that Tenant not then be in default hereunder in any respect; and (v) Tenant or the proposed subtenant or assignee (collectively, “Transferee”) shall agree to pay Landlord, upon demand, as Additional Rent, a sum equal to the additional costs, if any, incurred by Landlord for maintenance and repair as a result of any change in the nature of occupancy caused by such subletting or assignment. “Transfer Premium” shall mean all rent, Additional Rent or other consideration payable by a Transferee in connection with a Transfer in excess of the Base Rent and Direct Costs payable by Tenant under this Lease during the term of the Transfer (and if such Transfer is for less than all of the Premises, the Transfer Premium shall be calculated on a rentable square foot basis) less any reasonable hard and soft costs for any demising and/or fit up work, rent abatement periods, brokerage commissions and attorneys’ fees actually paid by Tenant in connection with such Transfer amortized on a straight-line basis over the term of the Transfer. The calculation of “Transfer Premium” shall also include, but not be limited to, key money, bonus money or other cash consideration paid by a Transferee to Tenant in connection with such Transfer, and any payment in excess of fair market value for services rendered by Tenant to the Transferee and any payment in excess of fair market value for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to the Transferee in connection with such Transfer. Any Transfer of this Lease which is not in compliance with the provisions of this Article 15 shall be voidable by written notice from Landlord and shall, at the option of Landlord, terminate this Lease. In no event shall the consent by Landlord to any Transfer be construed as relieving Tenant or any Transferee

-28-

DOCPROPERTY "DocID" \* MERGEFORMAT

from obtaining the express written consent of Landlord to any further Transfer, or as releasing Tenant from any liability or obligation hereunder whether or not then accrued and Tenant shall continue to be fully liable therefor.

(e) Notwithstanding anything to the contrary contained in this Article 15, with the exception of any Permitted Transfer, Landlord shall have the option, by giving written notice to Tenant within thirty (30) days after Landlord’s receipt of a request for consent to a proposed Transfer, to terminate this Lease as to the portion of the Premises that is the subject of the proposed Transfer. If this Lease is so terminated with respect to less than the entire Premises, the Base Rent and Tenant’s Proportionate Share shall be prorated based on the number of rentable square feet retained by Tenant as compared to the total number of rentable square feet previously contained in the Premises, and this Lease as so amended shall continue thereafter in full force and effect, and upon the request of either party, the parties shall execute written confirmation of the same.

(f) Notwithstanding anything to the contrary contained in this Article 15, the following transfers shall, upon thirty (30) days prior written notice from Tenant to Landlord (each a “Permitted Transfer”) not require Landlord’s consent: (1) transfers of this Lease or of interests in or assets of Tenant to an entity into or with which Tenant is merged or consolidated, or (2) transfers of this Lease or of interests in or assets of Tenant to any entity which purchases all or substantially all of Tenant’s voting stock, partnership interests or other membership interests, or all or substantially all of Tenant’s assets (the transferee in clauses (1) or (2) being referred to as a “Tenant Successor”); (3) transfers to an entity which controls, is controlled by or is under common control with Tenant (each an “Tenant Affiliate”), provided and on the condition that in any of such events:

(i) Tenant shall have delivered to Landlord at least thirty (30) days prior to the effective date of any such transaction, (a) evidence that the net worth of the transferee that will be the tenant under this Lease after such transfer or acquisition is not less than, the greater of, (i) the net worth of Tenant on the Effective Date of this Lease, or (ii) the net worth of Tenant immediately preceding such transfer or transaction, (b) proof reasonably satisfactory to Landlord of such net worth and reputation, and (c) such information as to the nature of the assignee’s business and its financial responsibility as Landlord may reasonably require;

(iii) Such merger, consolidation, transfer or acquisition shall be for a good business purpose and not principally for the purpose of transferring this Lease.

Article 16
DAMAGE OR DESTRUCTION

-29-

DOCPROPERTY "DocID" \* MERGEFORMAT

If the Building is damaged by fire or other insured casualty and the insurance proceeds have been made available therefor by the holder or holders of any mortgages or deeds of trust covering the Premises or the Building, the damage shall be repaired by Landlord to the extent such insurance proceeds are available therefor and provided such repairs can, in Landlord’s sole opinion, be completed within two hundred seventy (270) days after the necessity for repairs as a result of such damage becomes known to Landlord, without the payment of overtime or other premiums, and until such repairs are completed rent shall be abated in proportion to the part of the Premises which is unusable by Tenant in the conduct of its business (but there shall be no abatement of rent by reason of any portion of the Premises being unusable for a period equal to one (1) day or less). However, if the damage is solely the result of the willful misconduct or gross negligence of Tenant, its employees, agents, contractors, guests, invitees and the like, there shall be no abatement of rent, unless and to the extent Landlord receives rental income insurance proceeds, and Tenant shall not have any of the termination rights described herein. Upon the occurrence of any damage to the Premises, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Section 14(a)(iii)(A) above; provided, however, that if the cost of repair of improvements within the Premises by Landlord exceeds the amount of insurance proceeds received by Landlord from Tenant’s insurance carrier, as so assigned by Tenant, such excess costs shall be paid by Tenant to Landlord prior to Landlord’s repair of such damage. If repairs cannot, in Landlord’s opinion, be completed within two hundred seventy (270) days after the necessity for repairs as a result of such damage becomes known to Landlord without the payment of overtime or other premiums, either Landlord or Tenant may terminate this Lease, by notifying the other party hereto in writing of such termination within sixty (60) days after the occurrence of such damage, such notice to include a termination date which would provide Tenant sixty (60) days to vacate the Premises. In addition, Landlord may elect to terminate this Lease if the Building shall be damaged by fire or other casualty or cause, whether or not the Premises are affected, if the damage is not fully covered, except for deductible amounts, by Landlord’s insurance policies. Finally, if the Premises or the Building is damaged to any substantial extent during the last twelve (12) months of the Term, then notwithstanding anything contained in this Article 16 to the contrary, either Landlord or Tenant shall have the option to terminate this Lease by giving written notice to the other party hereto of the exercise of such option within sixty (60) days after the occurrence of such damage. A total destruction of the Building shall automatically terminate this Lease. In no event shall a closure of the Building to protect public health constitute damage as used in this Article 16, and a casualty shall only be deemed to occur where the Tenant’s is unable to use the Premises or the Building for the permitted uses described herein. Except as provided in this Article 16, there shall be no abatement of rent and no liability of Landlord by reason of any injury to or interference with Tenant’s business or property arising from such damage or destruction or the making of any repairs, alterations or improvements in or to any portion of the Building or the Premises or in or to fixtures, appurtenances and equipment therein. Tenant understands that Landlord will not carry insurance of any kind on Tenant’s furniture, furnishings, trade fixtures or equipment, and that Landlord shall not be obligated to repair any damage thereto or replace the same. Tenant acknowledges that Tenant shall have no right to any proceeds of insurance carried by Landlord relating to property damage.

The foregoing notwithstanding, if the lessor under any such lease or the holder or holders of any such mortgage or deed of trust shall advise Landlord that they desire or require this Lease to be prior and superior thereto, upon written request of Landlord to Tenant, Tenant agrees to promptly execute, acknowledge and deliver any and all documents or instruments which Landlord or such lessor, holder or holders deem necessary or desirable for purposes thereof. Tenant agrees that in the event any proceedings are brought for the foreclosure of any mortgage or deed of trust or any deed in lieu thereof, to attorn to the mortgagee under such mortgage or deed of trust, such mortgagee’s successor purchaser or any of their successors or assigns upon any such foreclosure sale or deed in lieu thereof as so requested to do so by such purchaser and to recognize such purchaser as the lessor under this Lease; provided, however, that such mortgagee or its successor shall not be liable for or bound by, (i) any payment of any rent installment which may have been made more than thirty (30) days before the due date of such installment, (ii) any act or omission of or default by Landlord under this Lease except for such acts or omissions continuing beyond the date of attornment (such mortgagee, or such successor, shall also be subject to the continuing obligations of Landlord under this Lease to the extent arising from and after such succession to the extent of such mortgagee’s or such successor’s interest in the Building), (iii) any credit, claims, setoffs or defenses which Tenant may have against Landlord except for any such credit, claims, setoffs or defenses which result from acts or omissions continuing beyond the date of attornment, or (iv) any material modification or material amendment to this Lease for which such mortgagee’s consent is required, but has not been obtained, under a mortgage or deed of trust. Tenant, upon the reasonable request by such mortgagee or such successor in interest, shall execute and deliver within five (5) business days of such request an instrument or instruments in form and substance reasonably acceptable to Tenant confirming such attornment. Tenant agrees to provide copies of any notices of Landlord’s default under this Lease to any mortgagee, deed of trust beneficiary and mezzanine lender whose address has been provided to Tenant in writing by Landlord and Tenant shall provide such mortgagee, deed of trust beneficiary and mezzanine lender the same time frames as Landlord shall have under this Lease after receipt of such notice within which to cure any such default. 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 18
EMINENT DOMAIN

If at least 50% of the Premises or the Building or so much thereof as to render the balance unusable by Tenant shall be taken under power of eminent domain, or is sold, transferred or conveyed in lieu thereof, this Lease shall automatically terminate as of the date of such condemnation, or as of the date possession is taken by the condemning authority, at Landlord’s option. No award for any partial or entire taking shall be apportioned, and Tenant hereby assigns to Landlord any award which may be made in such taking or condemnation, together with any and all rights of Tenant now or hereafter arising in or to the same or any part thereof; provided,

however, that nothing contained herein shall be deemed to give Landlord any interest in or to require Tenant to assign to Landlord any award made to Tenant for the taking of personal property and trade fixtures belonging to Tenant and removable by Tenant at the expiration of the Term hereof as provided hereunder or for the interruption of, or damage to, Tenant’s business. In the event of a partial taking described in this Article 18, or a sale, transfer or conveyance in lieu thereof, which does not result in a termination of this Lease, the rent shall be apportioned according to the ratio that the part of the Premises remaining useable by Tenant bears to the total area of the Premises. Any governmental action requiring businesses to close temporarily shall not be considered a condemnation or eminent domain hereunder, and any governmental action for the purpose of protecting public safety (e.g., to protect against acts of war, the spread of communicable diseases, or an infestation) shall not be considered a temporary taking for “public use” entitling Tenant to any government compensation, rental abatement or other remedy. Tenant, hereby irrevocably waives and releases its rights under any present or future Law that purports to govern the rights of Landlord and Tenant in such circumstances in the absence of express agreement is hereby waived by the parties and shall have no application.

Article 19

Each of the following acts or omissions of Tenant or of any guarantor of Tenant’s performance hereunder, or occurrences, shall constitute an “Event of Default”:

(b) Except as set forth in items (a) above and (c) through and including (g) below, failure to perform or observe any other covenant or condition of this Lease to be performed or observed within thirty (30) days following written notice to Tenant of such failure;

(f) Tenant’s failure to cause to be released any mechanics liens filed against the Premises or the Building within twenty (20) days after the date the same shall have been filed or recorded;

(g) Tenant executes a Transfer or other purported assignment or sublease in violation of Article 15 herein; or

(h) Tenant’s failure to observe or perform according to the provisions of Article 7 (Use) or Article 14 (Insurance), within three (3) business days after notice from Landlord.

All Events of Default by Tenant of any covenant or condition of this Lease shall be deemed by the parties hereto to be material.

Article 20
REMEDIES

(a) Upon the occurrence of an Event of Default under this Lease as provided in Article 19 hereof, Landlord may exercise all of its remedies as may be permitted by law and including without limitation, terminating this Lease, reentering the Premises and removing all persons and property therefrom, which property may be stored by Landlord at a warehouse or elsewhere at the risk, expense and for the account of Tenant. If Landlord elects to terminate this Lease, Landlord shall be entitled to recover from Tenant the aggregate of all amounts permitted by law, including but not limited to the sum of (i) the worth at the time of award of any unpaid Rent that had accrued at the time of such termination; plus (ii) an amount equal to the total Rent waived by Landlord during the Rent Abatement Period; plus (iii) the costs of restoring the Premises to the condition required under the terms of this Lease; plus, (iv) an amount (the “Election Amount”) equal to either (A) the positive difference (if any, and measured at the time of such termination) between (1) the then-present value of the total Rent and other benefits that would have accrued to Landlord under this Lease for the remainder of the Term if Tenant had fully complied with the Lease minus (2) the then-present cash rental value of the Premises as determined by Landlord for what would be the then-unexpired Term if the Lease remained in effect, computed using the discount rate of the Federal Reserve Bank of San Francisco at the time of the award plus one (1) percentage point, or (B) twelve (12) months (or such lesser number of months as may then be remaining in the Term) of Base Rent and Additional Rent at the rate last payable by Tenant pursuant to this Lease, in either case as Landlord specifies in such election. Landlord and Tenant agree that the Election Amount represents a reasonable forecast of the minimum damages expected to occur in the event of a breach, taking into account the uncertainty, time and cost of determining elements relevant to actual damages, such as fair market rent, time and costs that may be required to re-lease the Premises, and other factors; and that the Election Amount is not a penalty. As used in item (i), above, the “worth at the time of award” shall be computed by allowing interest at the rate set forth in Section 20(e), below, but in no case greater than the maximum amount of such interest permitted by law.

(b) Nothing in this Article 20 shall be deemed to affect Landlord’s right to indemnification for liability or liabilities arising prior to the termination of this Lease for personal injuries or property damage under the indemnification clause or clauses contained in this Lease.

-33-

DOCPROPERTY "DocID" \* MERGEFORMAT

(c) Notwithstanding anything to the contrary set forth herein, Landlord’s re-entry to perform acts of maintenance or preservation of or in connection with efforts to relet the Premises or any portion thereof, or the appointment of a receiver upon Landlord’s initiative to protect Landlord’s interest under this Lease shall not terminate Tenant’s right to possession of the Premises or any portion thereof and, until Landlord does elect to terminate this Lease in writing, this Lease shall continue in full force and effect and Landlord may enforce all of Landlord’s rights and remedies hereunder. 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.

(d) All rights, powers and remedies of Landlord hereunder and under any other agreement now or hereafter in force between Landlord and Tenant shall be cumulative and not alternative and shall be in addition to all rights, powers and remedies given to Landlord by law, and the exercise of one or more rights or remedies shall not impair Landlord’s right to exercise any other right or remedy. In addition, in the event of any eviction moratorium, to the extent otherwise allowed by law, Landlord may keep this Lease in effect and sue for rent damages and otherwise exercise Landlord’s rights and remedies under this lease including, without limitation, Landlord’s right to apply or draw upon any security deposit, letter of credit or other security enhancements.

(e) Any amount due from Tenant to Landlord hereunder which is not paid when due shall bear interest at twelve (12%) percent from the due date until paid, unless otherwise specifically provided herein, but the payment of such interest shall not excuse or cure any default by Tenant under this Lease. In addition to such interest: (i) if Base Rent is not paid on or before the fifth (5th) day of the calendar month for which the same is due, a late charge equal to ten percent (10%) of the amount overdue or $100, whichever is greater, shall be immediately due and owing and shall accrue for each calendar month or part thereof until such rental, including the late charge, is paid in full, which late charge Tenant hereby agrees is a reasonable estimate of the damages Landlord shall suffer as a result of Tenant’s late payment, and (ii) an additional charge of $25 shall be assessed for any check given to Landlord by or on behalf of Tenant which is not honored by the drawee thereof; which damages include Landlord’s additional administrative and other costs associated with such late payment and unsatisfied checks and the parties agree that it would be impracticable or extremely difficult to fix Landlord’s actual damage in such event. Such charges for interest and late payments and unsatisfied checks are separate and cumulative and are in addition to and shall not diminish or represent a substitute for any or all of Landlord’s rights or remedies under any other provision of this Lease.

(f) Except as expressly set forth in this Lease, in the event of any default, breach or violation of Tenant’s rights under this Lease by Landlord, Tenant’s exclusive remedies shall be an action for specific performance or action for actual damages. Without limiting any other waiver by Tenant which may be contained in this Lease, Tenant hereby waives the benefit of any law granting it the right to perform Landlord’s obligation, or the right to terminate this Lease on account of any Landlord default.

Article 21

DOCPROPERTY "DocID" \* MERGEFORMAT

Tenant shall not assign any of its rights hereunder and in the event an attempted assignment is made, it shall be void.

Article 24
WAIVER

No waiver by Landlord of any provision of this Lease shall be deemed to be a waiver of any other provision hereof or of any subsequent breach by Tenant of the same or any other provision. No provision of this Lease may be waived by Landlord, except by an instrument in writing executed by Landlord. Landlord’s consent to or approval of any act by Tenant requiring Landlord’s consent or approval shall not be deemed to render unnecessary the obtaining of Landlord’s consent to or approval of any subsequent act of Tenant, whether or not similar to the act so consented to or approved. No act or thing done by Landlord or Landlord’s agents during the Term of this Lease shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept such surrender shall be valid unless in writing and signed by Landlord. 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. Any payment by Tenant or receipt by Landlord of an amount less than the total amount then due hereunder shall be deemed to be in partial payment only thereof and not a waiver of the balance due or an accord and satisfaction, notwithstanding any statement or endorsement to the contrary on any check or any other instrument delivered concurrently therewith or in reference thereto. Accordingly, Landlord may accept any such amount and negotiate any such check without prejudice to Landlord’s right to recover all balances due and owing and to pursue its other rights against Tenant under this Lease, regardless of whether Landlord makes any notation on such instrument of payment or otherwise notifies Tenant that such acceptance or negotiation is without prejudice to Landlord’s rights.

At any time prior to the expiration of the Lease Term and upon Landlord’s

reasonable belief that certain Hazardous Materials tests are advisable, Landlord shall have the right following reasonable written notice (except in the event of an emergency), to enter upon the Premises at all reasonable times during normal business hours in order to conduct appropriate tests and to deliver to Tenant the results of such tests to attempt to demonstrate that contamination has occurred as a result of Tenant’s use of the Premises.

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

Tenant shall be responsible for the cost to repair all damage to the Premises resulting from the removal of any of such items from the Premises, provided that Landlord shall have the right to either (I) cause Tenant to perform said repair work, or (II) perform said repair work itself, at Tenant’s expense (with any such costs incurred by Landlord to be reimbursed by Tenant to Landlord within fifteen (15) days following demand therefor from Landlord).

(c) Whenever Landlord shall reenter the Premises as provided in Article 20 hereof, or as otherwise provided in this Lease, any property of Tenant not removed by Tenant upon the expiration of the Term of this Lease (or within forty-eight (48) hours after a termination by reason of Tenant’s default), as provided in this Lease, shall be considered abandoned and Landlord may remove any or all of such items and dispose of the same in any manner or store the same in a public warehouse or elsewhere for the account and at the expense and risk of Tenant, and if Tenant shall fail to pay the cost of storing any such property after it has been stored for a period of thirty (30) days or more, Landlord may sell any or all of such property at public or private sale, in such manner and at such times and places as Landlord, in its sole discretion, may deem proper, without notice to or demand upon Tenant, for the payment of all or any part of such charges or the removal of any such property, and shall apply the proceeds of such sale as follows: first, to the cost and expense of such sale, including reasonable attorneys’ fees and costs for services rendered; second, to the payment of the cost of or charges for storing any such property; third, to the payment of any other sums of money which may then or thereafter be due to Landlord from Tenant under any of the terms hereof; and fourth, the balance, if any, to Tenant.

(e) Notwithstanding anything to the contrary contained in this Lease, if any portion of the Premises is used as a laboratory (“Lab Space”), then, at least thirty (30) days prior to Tenant’s surrender of possession of the Premises (or in the event of an earlier termination of this Lease, as soon as reasonably possible following such termination), Tenant shall provide Landlord with a facility decommissioning and Hazardous Materials closure plan for the Lab Space which complies with the American National Standards Institute’s Laboratory Decommissioning guidelines (ANSI/AIHA Z9.11-2008) or any successor standards published by ANSI or any successor organization (or, if ANSI and its successors no longer exist, a similar entity publishing similar standards) (“Exit Survey”) prepared by an independent third party state-certified professional with appropriate expertise, in a form reasonably acceptable to Landlord. The Exit Survey must confirm that the Lab Space is in a clean and safe condition and free and clear of any Hazardous Materials caused by Tenant or any Tenant Party.

In the event that during the term of the Lease, in Landlord’s sole discretion, Tenant’s use of the Premises may have been in violation of Hazardous Material Laws, then Landlord may require that Tenant provide an Environmental Assessment for the Premises upon Tenant’s surrender of the Premises in addition to the Exit Survey. In addition, Tenant agrees to remain responsible after the surrender of the Premises for the remediation of any recognized environmental conditions caused by Tenant’s use of the Premises which are set forth in the Exit Survey (and the Environmental Assessment as applicable) in accordance with a remediation plan reasonably approved by Landlord pursuant to Section 28(k).

Failure by Tenant timely to send a notice under this subparagraph (a) shall constitute an irrevocable waiver of Tenant’s right to extend the Term, understanding that time is of the essence for the giving of any such notice.

(b) Landlord’s Response. If Tenant timely delivers a notice under subparagraph (a) above, Landlord shall furnish Tenant with Landlord’s estimate of the Base Rent rate equal to 95% of the Fair Market Rent Rate (as defined below) for the Premises for the Extension Term (once determined pursuant to the terms and provisions set forth below, the “Extension Rent Rate”, which in no event shall be less than the Base Rent rate in effect immediately prior to the Extension Term) no later than thirty (30) days following Landlord’s receipt of such notice. Within thirty (30) days after Landlord furnishes its estimate of the Extension Rent Rate to Tenant under the preceding sentence, Tenant shall, by written notice delivered to Landlord, either (i) give Landlord notice accepting Landlord’s estimate of the Extension Rent Rate for the Extension Term, or (ii) give Landlord notice disputing Landlord’s estimate of such Extension Rent Rate, which notice under clause (ii) shall state Tenant’s estimate of such Extension Rent Rate. Failure timely to give a notice disputing Landlord’s estimate of such Extension Rent Rate shall constitute an acceptance of Landlord’s determination of such Extension Rent Rate.

(c) Arbitration. If Tenant disputes Landlord’s determination of the Extension Rent Rate under subparagraph (b)(ii) above, the parties shall use good faith efforts to resolve such dispute for a period of thirty (30) days after such dispute notice is delivered. If, after such thirty (30) day period, the dispute over such Extension Rent Rate is not resolved, then either party may cause the matter of the Fair Market Rent Rate to be submitted to arbitration as set forth below, by giving notice of such submission to the other party. Each of Landlord and Tenant, within twenty (20) days after notice of such submission to arbitration, shall appoint as an arbitrator a commercial real estate broker with at least ten (10) years’ experience as a broker for first-class life sciences buildings in the suburban metro Boston, Massachusetts market, and shall give notice of such appointment to the other party. If either Landlord or Tenant shall fail timely to appoint an arbitrator, the other may apply to the Boston Office of the American Arbitration Association (“AAA”) for appointment of such an arbitrator five (5) Business Days after notice of such failure to the delinquent party if such arbitrator has not then been appointed. The two arbitrators shall, within five (5) Business Days after appointment of the second arbitrator, appoint a third arbitrator who shall be similarly qualified. If the two arbitrators are unable to agree timely on the selection of the third arbitrator, then either arbitrator on behalf of both may request such appointment from the Boston office of the AAA. The arbitration shall be conducted in accordance with the commercial arbitration rules of the AAA insofar as such rules are not inconsistent with the provisions of this Lease (in which case the provisions of this Lease shall govern). The arbitrators shall be charged to reach a majority written decision in accordance with the standards for Fair Market Rent Rate, within thirty (30) days after the third arbitrator is appointed, and if the arbitrators are unable to reach such a majority decision, the Fair Market Rent Rate shall be deemed to be the average of the two closest determinations made and simultaneously issued by the three arbitrators. The arbitrators shall have no authority or jurisdiction to make any other determination of such amount. Each party shall bear the costs of its appointed arbitrator; otherwise, the cost of the arbitration (exclusive of each party’s witness and attorneys’ fees, which shall be paid by such party) shall be borne equally by the parties. If the AAA shall cease to provide arbitration for commercial disputes in Boston, the second or third arbitrator, as the case may be, shall be appointed by any successor organization providing substantially the same services, and in the absence of such an organization, by a court of competent jurisdiction under the arbitration act of the State of California. For any period during which the Extension Rent Rate is in dispute hereunder, Tenant shall make payment on account of the Extension Rent Rate at the rate estimated

by Landlord as such Extension Rent Rate, and the parties shall adjust for overpayments or underpayments within thirty (30) days after the decision of the arbitrators is announced.

(d) Fair Market Rent Rate. The “Fair Market Rent Rate” for the Extension Term shall mean the annual fair market rent per square foot for the Premises for a term coterminous with the Extension Term under the terms of this Lease, as though the Premises were in the condition then existing or in such better condition as such space is required to be maintained hereunder. In making such determination, reference shall be made to lease transactions for comparable office space in the Building and comparable buildings in the Framingham office market, and appropriate adjustments to the rent rates in such comparable transactions shall be made for any relevant factors, including, without limitation, the timing of the transaction, the location and condition of the space, the quality of the Building, and any free rent, tenant improvements or other tenant concessions (or the lack thereof). Without limiting the generality of the foregoing adjustments, if the rent rate in a comparable transaction was determined based on a percentage discount to fair market rent, then the amount of such discount shall be disregarded (i.e., added back into the rental rate) for purposes of determining the Fair Market Rent Rate hereunder.

(e) Confirmatory Instrument. If Tenant shall exercise the Extension Option in accordance with this Section, the provisions of this Section shall be self-operative, but upon request by either party after determination of the Extension Rent Rate for the Extension Term, the parties shall execute an agreement specifying the Extension Rent Rate for the Extension Term and acknowledging the extension of the Term.

(f) Conditions. Notwithstanding any provision of this Section to the contrary, the Extension Option shall be void, at Landlord’s election, if at the time of exercise or upon the expiration of the Initial Term (i) Tenant is in default hereunder, after any applicable notice and cure periods have expired, at the time Tenant elects to extend the Term or at the time the Term would expire but for such extension, or (ii) Tenant is in actual occupancy of less than seventy five percent (75%) of the Premises or at the time of Tenant’s exercise of the Extension Option more than twenty five percent (25%) of the Premises is subleased (other than pursuant to a Permitted Transfer), or an assignment of the Lease (other than in connection with a Permitted Transfer) is then in full force and effect.

Article 34
RIGHT OF FIRST OFFER

(a) Provided that (i) Tenant is not in default under the terms of this Lease, and (ii) Tenant is in actual occupancy of 70% or more of the Premises, Tenant shall have a continuing right of first offer to lease any space from time to time made available in the Building by Landlord which space is located on the First (1st ) Floor, the Second (2nd) Floor, the Third (3rd) Floor or the Fourth (4th) Floor of the Building (the “Offer Space”) as provided below. At any time that Landlord shall determine that such Offer Space or portion thereof is to be available for lease, then Landlord shall advise Tenant (the “Advice”) of the availability of such portion of the Offer Space to Tenant for the remainder of the Term of this Lease and any extensions at a Base Rent equal to the then Market Rate (hereinafter defined) for such Offer Space. Tenant may lease such Offer Space or portion thereof as set forth in the Advice in its entirety only, under such terms, by delivering written notice of exercise to Landlord (“Notice of Exercise”) within ten (10) business

days after the date of receipt of the Advice, except that Tenant shall have no such Right of First Offer and Landlord need not provide Tenant with an Advice, if Tenant is in default beyond applicable cure periods after notice under the Lease at the time of Tenant’s Notice of Exercise.

(b)

(i) The term for the applicable Offer Space shall commence upon the later of ninety (90) days after the date Tenant gives its Notice of Exercise and the commencement date stated in the Advice and thereupon such Offer Space shall be considered a part of the Premises, provided that, except for Base Rent for the Offer Space, all of the terms and conditions of this Lease shall apply to the Offer Space.

(ii) Notwithstanding the foregoing, in the event that (A) Tenant’s Notice of Exercise shall have been delivered within the first twenty four (24) months of the Term of this Lease, and (B) the applicable Offer Space is not Lab Space (as defined above), the Base Rent and any Additional Rent shall be at the same rates and on the same terms as the Base Rent and Additional Rent for the original Premises, but pro-rated based on the size of the applicable Offer Space and the number of full calendar months remaining in Term as of the date Rent commences with respect to the Offer Space. If the applicable Offer Space is Lab Space the Base Rent and any Additional Rent shall be the Market Rate for Lab Space.

(iii) The applicable Offer Space (including improvements) shall be accepted by Tenant in its condition and as-built configuration existing on the date Tenant gives its Notice of Exercise, unless the Advice specifies any work to be performed by Landlord in the Offer Space, in which case Landlord shall perform such work in the Offer Space and the commencement date for the Offer Space shall not be deemed to have occurred until such work is substantially complete.

(c) The rights of Tenant hereunder with respect to such Offer Space described in the applicable Advice shall terminate on Tenant's failure to exercise its Right of First Offer within the ten (10) business day period provided above.

(d) For purposes hereof, the Market Rate shall mean the then annual rental rate per square foot as determined by Landlord and as set forth by Landlord in the Advice, for space comparable to the Offer Space in the Building and other buildings comparable to the Building.

(e) Notwithstanding anything herein to the contrary, Tenant's Right of First Offer is subject and subordinate to the any existing expansion rights (whether such rights are designated as a right or first offer, right of first refusal, expansion option or otherwise) of any tenant of the Property under its lease as existing on the date hereof, and to the right of Landlord to renew or to extend the lease of any tenant then already in occupancy whether or not pursuant to an existing right of extension.

(f) Notwithstanding anything herein to the contrary, if Tenant does not timely give a Notice of Exercise with respect to any Offer Space or Tenant declines to exercise its option to lease the Offer Space, Landlord shall not lease any of such Offer Space without again giving Tenant an Advice and its first offer rights under this section if Landlord has not entered into a binding and effective lease of the entire Offer Space to a single tenant within twelve (12) months after the Advice.

Article 35
TEMPORARY SPACE

(a) Tenant shall lease temporary space from Landlord on the fourth (4th) floor of the Building, agreed to consist of 27,681 rentable square feet of space, as identified in Exhibit G attached hereto (the “Temporary Space”), during the period commencing on the Effective Date of this Lease and ending thirty (30) days after the Commencement Date. Rent for the Temporary Space shall be in the amount of $81,612.92 per month, provided that all such rent shall be abated in accordance with Section 35(c) below. Tenant has inspected the Temporary Space and shall accept such space in its “as is” condition, which condition shall be substantially similar to the condition of other similar space in the Building, and Tenant shall be prohibited from moving any walls or other structures. Landlord shall install temporary furniture which Tenant may lease, at Landlord’s expense, from its furniture vendor for Tenant’s use in the Temporary Space. Tenant shall be permitted to make purely cosmetic alterations to such space at Tenant’s sole expense, subject to the conditions set forth in this Lease, provided that Tenant shall remove any such alterations as directed by Landlord at the termination of such temporary occupancy, and surrender the Temporary Space in the substantially same condition as on the Effective Date of this Lease.

(b) Tenant will vacate the Temporary Space no later than thirty (30) days after the Commencement Date for the Premises, and in the event that Tenant does not vacate the temporary space by that date, (i) rent will be payable to Landlord, thereof at the same holdover rates as set forth for the Premises in this Lease prorated on a per square foot basis, and (ii) such failure shall constitute an Event of Default under this Lease. Tenant’s use and occupancy of the Temporary Space shall be on the same terms and conditions set forth in this Lease, including Landlord's obligation to provide those services set forth herein, revocable by Landlord at any time in the event of a Default by Tenant under the terms of this Lease. Tenant’s right to occupy the Temporary Space shall terminate thirty (30) days after the Commencement Date, or if prior to the Commencement Date there has been an Event of Default by Tenant the right to occupy the Temporary Space shall terminate on the date of such Default.

(c) Provided Tenant shall not have been otherwise in default of any of its obligations under this Lease beyond any applicable cure or grace period, this Lease remains in full force and effect, and Tenant shall have provided all the information and approvals reasonably required of Tenant in accordance with the Tenant Work Letter set forth in Exhibit D, each to the extent then applicable, Landlord waives the payment of rent for the Temporary Space.
