SECOND AMENDMENT TO LEASE
(EXPANSION)

This Second Amendment to Lease (the "Agreement") is entered into as of June 16, 2022 (“Effective Date”), by and between WESTPORT OFFICE PARK, LLC, a Delaware limited liability company (formerly a California limited liability company) ("Landlord"), and ADICET THERAPEUTICS, INC., a Delaware corporation ("Tenant"), with respect to the following facts and circumstances:

Landlord and Tenant are parties to that certain Lease Agreement dated as of October 31, 2018, as amended by that certain First Amendment to Lease dated as of December 30, 2020 (collectively, the "Original Lease") of certain premises comprising approximately 50,305 square feet (the "Existing Premises") within the building located at 0000 Xxxxxx Xxxxxxx, Xxxxxxx Xxxx, Xxxxxxxxxx 00000 (the "1000 Building"), and more particularly described in the Original Lease. Capitalized terms used and not otherwise defined herein shall have the meanings given those terms in the Original Lease. Effective as of the date hereof, all references to the "Lease" shall refer to the Original Lease, as amended by this Agreement.

Landlord and Tenant desire to amend the Original Lease to add additional space on the terms and conditions provided herein.

IT IS, THEREFORE, agreed as follows:

1.As used in this Agreement, the following terms have the following meanings:

"Expansion Space" means a portion of the second floor of the building located at 0000 Xxxxxx Xxxxxxx, Xxxxxxx Xxxx, Xxxxxxxxxx 00000 within the Project ("1200 Building" and collectively with the 1000 Building, the "Buildings"), commonly known as Suite 201 containing approximately 12,204 rentable square feet of area, and more particularly shown on Exhibit"A‑1" attached hereto.

"Expansion Space Commencement Date" shall mean the earliest of (a) the date upon which Tenant first commences to conduct business in the Expansion Space, or (b) fourteen (14) days after Landlord delivers the Expansion Premises to Tenant pursuant to Section 3 of this Agreement.

"Expansion Improvements" means the Tenant Improvements constructed in the Expansion Space in accordance with the Tenant Work Letter attached hereto as Exhibit "B"("Tenant Work Letter").

2.Effective on the Expansion Space Commencement Date, the Premises shall be expanded to include the Expansion Space. Accordingly, effective on the Expansion Space Commencement Date, Landlord leases the Expansion Space to Tenant and Tenant leases the Expansion Space from Landlord, and the following terms of the Original Lease are amended as follows:

2.1The Expansion Space is added to the Premises such that the Premises shall be comprised of the Existing Premises and the Expansion Space, and Exhibit "A-1" attached hereto is hereby added to Exhibit "A" to the Original Lease.

2.2For purposes of applying the terms of the Lease to the Expansion Space, references to the "Building" shall be deemed references to the “1000 Building,” the "1200 Building," or the "Buildings" where the context so requires.

2.3The Maximum Parking Allocation with respect to the Expansion Space shall be twenty seven (27), which is based on a parking ratio of 2.25 non-exclusive parking spaces per one thousand (1,000) square feet of the rentable space in the Expansion Space.

2.4During the Expansion Space Term (as defined below), and subject to Applicable Laws, the Expansion Space shall be used and occupied by Tenant solely for general office and administrative purposes consistent with a first-class office building and for no other purposes without the prior written consent of Landlord.

2.5Building standard signage will be installed by Landlord on (i) the 1200 Building’s main lobby directory board, (ii) Tenant's main entry doors to the Expansion Space, and (iii) the monument serving the 1200 Building, at Tenant's sole cost and expense. Any change in such signage shall be only with Landlord's prior written consent, shall conform to Building standard signage and shall be at Tenant's sole cost and expense. The size, type, style, materials and colors of such signage, method of installation and specific location of such signage shall be subject to Section 32 of the Original Lease and Landlord's prior written approval in its sole discretion.

2.6Tenant's Building Percentage of Operating Expenses and Tenant's Tax Percentage shall be determined separately for the Existing Premises and the Expansion Space. Tenant shall be required to pay Tenant's Building Percentage of Operating Expenses and Tenant's Tax Percentage for the Expansion Space during the Expansion Space Term. With respect to the Existing Premises, Tenant's Building Percentage shall mean Tenant's percentage of the entire 1000 Building as determined by dividing the rentable area of the Existing Premises by the total rentable area of the 1000 Building, and Tenant's Tax Percentage shall mean the percentage determined by dividing the rentable area of the Existing Premises by the total rentable area of all buildings in the Project. With respect to the Expansion Space, Tenant's Building Percentage shall mean Tenant's percentage of the entire 1200 Building as determined by dividing the rentable area of the Expansion Space by the total rentable area of the 1200 Building, and Tenant's Tax Percentage shall mean the percentage determined by dividing the rentable area of the Expansion Space by the total rentable area of all buildings in

Accordingly, with respect to the Expansion Space during the Expansion Space Term, (a) Tenant's Building Only Percentage for the Expansion Space shall be 23.55%, (b) Tenant's Common Area Building Percentage for the Expansion Space shall be 1.20%, and (c) Tenant's Tax Percentage for the Expansion Space shall be 1.20%.

2.7The Term with respect to the Expansion Space shall commence on the Expansion Space Commencement Date, and the Expiration Date with respect to the Expansion Space shall be the date that is the day prior to the day that is thirty six (36) months after the Expansion Space Commencement Date (the "Expansion Space Term"). In the event that Tenant exercises an extension option pursuant to the Original Lease such extension shall not apply to the Expansion Space; provided, however, in the event the Original Lease terminates pursuant to its terms, such termination shall apply to the entire Premises then subject to the Original Lease (including the Expansion Space).

2.8During the Expansion Space Term Tenant agrees to pay Landlord Base Rent for the Expansion Space in accordance with the following schedule:

Period*	Annual Base Rent	Monthly Base Rent
01 – 12	$ 878,688.00	$ 73,224.00
13 – 24	$ 909,442.08	$ 75,786.84

The monthly Base Rent for the Expansion Space for the first month after the Expansion Space Commencement Date shall be payable upon the execution of this Agreement. The monthly Base Rent for the Expansion Space shall be payable in the manner provided for in the Original Lease.

3.Landlord shall use commercially reasonable efforts to deliver the Expansion Premises to Tenant in the condition required under this paragraph within three (3) business days after the Effective Date of this Agreement. Tenant shall accept the Expansion Space in its "AS IS" condition as of the date of this Agreement, reasonable wear and tear excepted, and otherwise broom clean and free and clear of all tenants, occupants, and personal property. Tenant agrees that except as expressly set forth in this Agreement and the Tenant Work Letter attached hereto as Exhibit B, Landlord has no obligation and has made no promise to alter, remodel, improve, or repair the Expansion Space, or any part thereof, or to repair, bring into compliance with applicable laws, or improve any condition existing in the Expansion Space as of the Expansion Space Commencement Date. The taking of possession of the Expansion Space by Tenant shall be conclusive evidence that the Expansion Space and the 1200

SMRH:4884-5429-6605.8 -3-

ACTIVE/117699601.1

Building were in good and satisfactory condition at the time possession was taken by Tenant, except for “latent defects” (as defined in Section 2.3 of the Lease). Neither Landlord nor Landlord's agents have made any representations or promises with respect to the condition of the 1200 Building, the Expansion Space, the land upon which the Buildings are constructed, the present or future suitability or fitness of the Expansion Space or the 1200 Building for the conduct of Tenant's particular business, or any other matter or thing affecting or related to the Buildings or the Expansion Space, and no rights, easements or licenses are acquired by Tenant by implication or otherwise, except as expressly set forth in this Agreement or the Lease. Any improvements or personal property located in the Expansion Space are delivered without any representation or warranty from Landlord, either express or implied, of any kind, including without limitation, title, merchantability, or suitability for a particular purpose. Notwithstanding anything in this Agreement to the contrary, Landlord warrants that the roof of the 1200 Building, the parking lots serving the Expansion Space, and the base building systems (including, without limitation, the HVAC, mechanical, electrical, life safety, and plumbing systems), elevator, or site lighting serving the Expansion Space (collectively, the “Covered Items”), other than those constructed by Tenant, shall be in good operating condition on the Expansion Space Commencement Date. If a non-compliance with such warranty exists as of the Expansion Space Commencement Date, or if one of such Covered Items should malfunction or fail within sixty (60) days after such date, Landlord shall, as Landlord’s sole obligation with respect to such matter, promptly after receipt of written notice from Tenant setting forth in reasonable detail the nature and extent of such non-compliance, malfunction or failure, rectify the same at Landlord’s expense. If Tenant does not give Landlord the required notice within such sixty (60) day period, Landlord shall have no obligation with respect to that warranty other than obligations regarding the Covered Items set forth elsewhere in the Lease. Tenant shall deliver to Landlord any modifications to Tenant's insurance required under the Original Lease to reflect the addition of the Expansion Space and Tenant's entry into the Expansion Space prior to the delivery of possession to Tenant. Landlord shall not be liable to Tenant or otherwise be in default hereunder in the event that Landlord is unable to deliver the Expansion Space to Tenant on the projected delivery date thereof due to the failure of any other tenant to timely vacate and surrender to Landlord such Expansion Space, or any portion thereof; provided, however, Landlord agrees to use its commercially reasonable efforts to enforce its rights to possession of such Expansion Space against such other tenant.

4.Subject to the terms hereof and provided that Tenant and its agents do not materially interfere with, or delay, work by Landlord in the Buildings, at Landlord's reasonable discretion, Landlord shall allow Tenant access to the Expansion Space fourteen (14) days prior to the Expansion Space Commencement Date for the purpose of Tenant installing equipment or fixtures, cabling and furniture in the Expansion Space. Prior to Tenant's entry into the Expansion Space as permitted by the terms of this Section 4, Tenant shall submit a schedule to Landlord, for its approval in its reasonable discretion, which schedule shall detail the timing and purpose of Tenant's entry. In connection with any such entry, Tenant acknowledges and agrees that Tenant's employees, agents, contractors, consultants, workmen, mechanics, suppliers and invitees shall reasonably cooperate, work in harmony and not materially interfere with Landlord or Landlord's contractors, agents or

SMRH:4884-5429-6605.8 -4-

ACTIVE/117699601.1

representatives in performing work in the 1200 Building, or interfere with the general operation of the Buildings or the Project. If at any time any such person representing Tenant shall not be cooperative or shall otherwise cause or threaten to cause any such disharmony or interference, including, without limitation, labor disharmony, and Tenant fails to immediately institute and maintain corrective actions as directed by Landlord, then Landlord may revoke Tenant's early entry rights upon twenty-four (24) hours' prior written notice to Tenant. Tenant acknowledges and agrees that any such entry into and occupancy of the Expansion Space or any portion thereof by Tenant or any person or entity working for or on behalf of Tenant shall be deemed to be subject to all of the terms, covenants, conditions and provisions of the Lease, excluding only the covenant to pay Rent (until the occurrence of the Expansion Space Commencement Date). Tenant further acknowledges and agrees that Landlord shall not be liable for any injury, loss or damage which may occur to any of Tenant's work made in or about the Expansion Space in connection with such entry or to any property placed therein prior to the Expansion Space Commencement Date, the same being at Tenant's sole risk and liability (except to the extent caused by the gross negligence or willful misconduct of Landlord or its agents or contractors). Tenant shall be liable to Landlord for any damage to any portion of the Expansion Space caused by Tenant or any of Tenant's employees, agents, contractors, consultants, workmen, mechanics, suppliers and invitees. In the event that the performance of Tenant's work in connection with such entry causes extra costs to be incurred by Landlord or requires the use of any Building services, Tenant shall promptly reimburse Landlord for such extra costs and/or shall pay Landlord for such Building services at Landlord's standard rates then in effect. In addition, Tenant shall hold Landlord harmless from and indemnify, protect and defend Landlord against any loss or damage to the Buildings or Expansion Space and against injury to any persons caused by Tenant's actions pursuant to this Section 4.

5.Landlord hereby represents and warrants to Tenant that it has dealt with no broker, finder or similar person in connection with this Agreement, and Tenant hereby represents and warrants to Landlord that it has dealt with no broker, finder or similar person in connection with this Agreement, other than Xxxxxxx & Xxxxxxxxx and CBRE (collectively, "Landlord's Broker") and CBRE ("Tenant's Broker"). Landlord and Tenant shall each defend, indemnify and hold the other harmless with respect to all claims, causes of action, liabilities, losses, costs and expenses (including without limitation attorneys' fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of the indemnifying party's dealings with any real estate broker, agent, finder or similar person other than Landlord's Broker and Tenant's Broker. The commission with respect to this Agreement shall be paid to Landlord's Broker by Landlord pursuant to a separate agreement. Landlord's Broker will pay Tenant's Broker a commission pursuant to a separate agreement. Nothing in this Agreement shall impose any obligation on Landlord to pay a commission or fee to any party other than Landlord's Broker.

6.As additional consideration for this Agreement, Tenant hereby certifies that:

(a)The Original Lease (as amended hereby) is in full force and effect.

SMRH:4884-5429-6605.8 -5-

(e)All of the representations and warranties of Tenant in the Original Lease are hereby remade.

8.Except as specifically provided herein, the terms and conditions of the Original Lease as amended hereby are ratified and confirmed and shall continue in full force and effect. This Agreement shall be binding on the heirs, administrators, successors and assigns (as the case may be) of the parties hereto. This Agreement, the Original Lease and the attached exhibits, which are hereby incorporated into and made a part of this Agreement, constitute the entire agreement of the parties with respect to all matters discussed herein and therein, including, but not limited to, all matters relating to the Premises and the leasing relationship and supersede all other agreements and understandings between the parties, both written and oral.

Tenant agrees that neither Tenant nor its agents or any other parties acting on behalf of Tenant shall disclose any matters set forth in this Agreement or disseminate or distribute any information concerning the terms, details or conditions hereof to any person, firm or entity other than Tenant’s attorneys, agents, assigns, accountants and consultants, or to an entity or person to whom disclosure is required by Applicable Laws, without obtaining the express written consent of Landlord. In the case of any inconsistency between the provisions of the Original Lease and this Agreement, the provisions of this Agreement shall govern and control. Submission of this Agreement by Landlord is not an offer to enter into this Agreement but rather is a solicitation for such an offer by Tenant. Landlord shall not be bound by this Agreement until Landlord has executed and delivered the same to Tenant. Time is of the essence of this Agreement and the provisions contained herein. Each signatory of this Agreement represents that she or he has the authority to execute and deliver the same on behalf of the party for which such signatory is acting, and that upon the execution by such signatory, this Agreement is binding on behalf of the party for which such signatory is acting and enforceable against such party in accordance with its terms.

9.Tenant Compliance.

The following disclosure is hereby made pursuant to applicable California law: "A Certified Access Specialist (CASp) can inspect the subject premises and determine whether the subject premises comply with all of the applicable construction-related accessibility standards under state law.

5.Notwithstanding anything to the contrary in the Lease, Tenant's obligation to pay rent and other amounts due under the Lease shall not be abated or limited in the event access to, use of, and/or services provided to the Premises, the Buildings, and/or the Project is or are prevented, limited or impaired in compliance with Applicable Laws or as a precaution in connection with a community health emergency, including any epidemic, quarantine, or infectious disease-related outbreak.

6.If Tenant is billed directly by a public utility with respect to Tenant's electrical usage at the Premises, upon request from time to time, Tenant shall provide monthly electrical utility usage for the Premises to Landlord for the period of time requested by Landlord (in electronic or paper format) or, at Landlord's option, provide any written authorization or other documentation required for Landlord to request information regarding Tenant's electricity usage with respect to the Premises directly from the applicable utility company.

TENANT WORK LETTER

This Tenant Work Letter is attached to and made a part of that certain Second Amendment to Lease dated June 16, 2022 (the "Amendment") between WESTPORT OFFICE PARK, LLC, a Delaware limited liability company (formerly a California limited liability company) ("Landlord"), and ADICET THERAPEUTICS, INC., a Delaware corporation ("Tenant"), which amends a lease between Landlord and Tenant (as modified from time to time, the "Lease") more particularly described in the Amendment. Any capitalized term used and not otherwise defined in this Tenant Work Letter has the meaning given such term in the Amendment (or, if not defined in the Amendment, the meaning given such term in the Lease). This Tenant Work Letter sets forth the terms and conditions relating to the construction of the Expansion Improvements in the Expansion Space. This Tenant Work Letter is essentially organized chronologically and addresses the issues of the construction of the Expansion Space, in sequence, as such issues will arise during the actual construction of the Expansion Space.

SECTION 1

BASE, SHELL AND CORE

Landlord has previously constructed the base, shell, and core (i) of the Expansion Space and (ii) of the floor(s) of the 1200 Building on which the Expansion Space are located (collectively, the "Base, Shell, and Core"), and subject to correction of latent defects (as defined in Section 2.3 of the Lease) subsequently discovered, Tenant shall accept the Base, Shell and Core and the Expansion Space in their current "As-Is" condition existing as of the date of the Amendment and the Expansion Space Commencement Date, except as otherwise expressly provided in the Lease and this Tenant Work Letter. Tenant shall install in the Expansion Space certain "Tenant Improvements" (as defined below) pursuant to the provisions of this Tenant Work Letter. Except for Landlord's obligation to disburse the Tenant Improvement Allowance as described below, Landlord shall not be obligated to make or pay for any alterations or improvements to the Expansion Space, the 1200 Building or the Project. Notwithstanding anything to the contrary contained herein, Landlord covenants to correct, at its sole cost and not as an Operating Expense payable by Tenant, any failure of the existing exterior path of travel for the Expansion Space to comply with current codes, including without limitation the Americans with Disabilities Act, as reasonably interpreted by Landlord's architect as of the date of the Lease, to the extent such correction is reasonably necessary in order to obtain a building permit or a certificate of occupancy for the Tenant Improvements in the Expansion Space; provided that nothing contained herein shall be deemed to prohibit Landlord from obtaining a variance or relying upon a grandfathered right in order to achieve compliance with those codes.

SECTION 2 TENANT IMPROVEMENTS

ACTIVE/117699601.1

2.1 Tenant Improvement Allowance. Tenant shall be entitled to a one-time tenant improvement allowance (the "Tenant Improvement Allowance") in the amount of up to, but not exceeding $10.00 per rentable square foot of the Expansion Space (i.e., up to $122,040.00, based on 12,204 rentable square feet in the Expansion Space), for the costs relating to the design, permitting, installation and construction of Tenant's improvements which are permanently affixed to the Expansion Space (the "Tenant Improvements"); provided, however, that Landlord shall have no obligation to disburse all or any portion of the Tenant Improvement Allowance to Tenant unless Tenant makes a request for disbursement pursuant to the terms and conditions of Section 2.2 below prior to that date which is twelve (12) months after the Expansion Space Commencement Date. In no event shall Landlord be obligated to make disbursements pursuant to this Tenant Work Letter in a total amount which exceeds the Tenant Improvement Allowance. Tenant shall not be entitled to receive any cash payment or credit against Rent or otherwise for any unused portion of the Tenant Improvement Allowance which is not used to pay for the Tenant Improvement Allowance Items (as such term is defined below). In no event shall the Tenant Improvement Allowance be used for purposes of constructing improvements in the Expansion Space for purposes of offering space for sublease or for the benefit of a subtenant.

ACTIVE/117699601.1

Landlord with cash in an amount (the "Over-Allowance Amount") by which the Final Costs exceed the Tenant Improvement Allowance (less any portion thereof already disbursed by Landlord, or in the process of being disbursed by Landlord, on or before the commencement of construction of the Tenant Improvements). The Over-Allowance Amount shall be disbursed by Landlord prior to the disbursement of any of the then remaining portion of the Tenant Improvement Allowance, and such disbursement shall be pursuant to the same procedure as the Tenant Improvement Allowance. In the event that, after the Final Costs have been delivered by Landlord to Tenant, the costs relating to the design and construction of the Tenant Improvements shall change, any additional costs necessary to such design and construction in excess of the Final Costs shall, to the extent they exceed the remaining balance of the Tenant Improvement Allowance, be paid by Tenant to Landlord immediately as an addition to the Over-Allowance Amount and, in any event, prior to the commencement of the construction of such changes, or, at Landlord's option, Tenant shall make payments for such additional costs out of its own funds, but Tenant shall continue to provide Landlord with the documents described in Sections 2.2.2.1(i), (ii), (iii) and (iv) above, for Landlord's approval, prior to Tenant paying such costs.

4.2.2.2 Coordination Fee. Tenant shall pay a logistical coordination fee (the "Coordination Fee") to Landlord in an amount equal to the product of (i) three percent (3%), and (ii) the sum of the Tenant Improvement Allowance, the Over-Allowance Amount, as such amount may be increased hereunder, and any other amounts expended by Tenant in connection with the design and construction of the Tenant Improvements, which Coordination Fee shall be for services relating to the coordination of the construction of the Tenant Improvements. Landlord shall be entitled to charge the amount of the Coordination Fee against the Tenant Improvement Allowance required to be contributed by Landlord hereunder, or if funds are not available from the Tenant Improvement Allowance for such purposes, Tenant will pay such amounts within twenty (20) days following delivery of Landlord's invoice.

4.2.2.3 Indemnity. Tenant's indemnity of Landlord as set forth in the Lease shall also apply with respect to any and all costs, losses, damages, injuries and liabilities

ACTIVE/117699601.1

related in any way to any act or omission of Tenant or Tenant's Agents, or anyone directly or indirectly employed by any of them, or in connection with Tenant's non-payment of any amount arising out of the Tenant Improvements and/or Tenant's disapproval of all or any portion of any request for payment. Such indemnity by Tenant, as set forth in the Lease, shall also apply with respect to any and all costs, losses, damages, injuries and liabilities related in any way to Landlord's performance of any ministerial acts reasonably necessary (i) to permit Tenant to complete the Tenant Improvements, and (ii) to enable Tenant to obtain any building permit or certificate of occupancy for the Expansion Space.

4.2.2.4 Insurance Requirements.

4.2.2.4.1 General Coverages. All of Tenant's Agents shall carry worker's compensation insurance covering all of their respective employees, and shall also carry public liability insurance, including property damage, all with limits, in form and with companies as are required to be carried by Tenant as set forth in the Lease.

4.2.2.4.2 Special Coverages. Tenant shall carry "Builder's All Risk" insurance in an amount covering the full replacement cost of all work in connection with the Tenant Improvements, and such other insurance as Landlord may require, it being understood and agreed that the Tenant Improvements shall be insured by Tenant pursuant to the Lease immediately upon completion thereof. Such insurance shall be in amounts and shall include such extended coverage endorsements as may be reasonably required by Landlord, and in form and with companies as are required to be carried by Tenant as set forth in the Lease.

4.2.2.4.3 General Terms. Certificates for all insurance carried pursuant to this Section 4.2.2.4 shall be delivered to Landlord before the commencement of construction of the Tenant Improvements and before the Contractor's equipment is moved onto the site. All such policies of insurance must contain a provision that the company writing said policy will give Landlord thirty (30) days prior written notice of any cancellation or lapse of the effective date or any reduction in the amounts of such insurance; notwithstanding the foregoing, Landlord acknowledges that, as of the date of this Lease, many insurers are unwilling to provide third parties (such as Landlord) with notice of cancellation and agrees that if the insured is unable to obtain such commitment from its insurer (despite the insured’s commercially reasonable efforts), then the insured's obligation pursuant to the provisions of this sentence will be to notify Landlord within five (5) days following the insured's receipt of any notice of cancellation from the insurer. In the event that the Tenant Improvements are damaged by any cause during the course of the construction thereof, Tenant shall immediately repair the same at Tenant's sole cost and expense. All policies carried under this Section 4.2.2.4 shall insure Landlord and Tenant, as their interests may appear, as well as Contractor and Tenant's Agents, and shall name as additional insureds Landlord's Property Manager, Landlord's Asset Manager, and all mortgagees and ground lessors of the 1200 Building. All insurance, except Workers' Compensation, maintained by Tenant's Agents shall preclude subrogation claims by the insurer against anyone insured thereunder. Such insurance shall provide that it is primary insurance as respects the owner and that any other insurance maintained by owner is excess and noncontributing with the insurance required hereunder. The requirements for the foregoing insurance shall not derogate from the provisions for indemnification of Landlord by Tenant under Section 4.2.2.3 of this Tenant Work Letter.

ACTIVE/117699601.1

4.2.3 Governmental Compliance. The Tenant Improvements shall comply in all respects with the following: (i) the Code and other state, federal, city or quasi-governmental laws, codes, ordinances and regulations, as each may apply according to the rulings of the controlling public official, agent or other person; (ii) applicable standards of the American Insurance Association (formerly, the National Board of Fire Underwriters) and the National Electrical Code; and (iii) building material manufacturer's specifications.

4.2.4 Inspection by Landlord. Landlord shall have the right to inspect the Tenant Improvements at all times, provided however, that Landlord's failure to inspect the Tenant Improvements shall in no event constitute a waiver of any of Landlord's rights hereunder nor shall Landlord's inspection of the Tenant Improvements constitute Landlord's approval of the same. Should Landlord disapprove any portion of the Tenant Improvements, Landlord shall notify Tenant in writing of such disapproval and shall specify the items disapproved, provided Landlord shall only disapprove work which is substandard as described in Section 2.2.2.2(ii) or due to non-compliance of any work with the Approved Working Drawings. Any defects or deviations in, and/or disapproval by Landlord of, the Tenant Improvements shall be rectified by Tenant at no expense to Landlord, provided however, that in the event Landlord determines that a defect or deviation exists or disapproves of any matter in connection with any portion of the Tenant Improvements and such defect, deviation or matter might adversely affect the mechanical, electrical, plumbing, heating, ventilating and air conditioning or life-safety systems of the 1200 Building, the structure or exterior appearance of the 1200 Building or any other tenant's use of such other tenant's leased premises, Landlord may, take such action as Landlord deems necessary, at Tenant's expense and without incurring any liability on Landlord's part, to correct any such defect, deviation and/or matter, including, without limitation, causing the cessation of performance of the construction of the Tenant Improvements until such time as the defect, deviation and/or matter is corrected to Landlord's satisfaction.

4.2.5 Meetings. Commencing upon the execution of the Amendment, Tenant shall hold weekly meetings at a reasonable time, with the Architect and the Contractor regarding the progress of the preparation of Construction Drawings and the construction of the Tenant Improvements, which meetings shall be held at a location designated by Landlord (unless such meetings are held by telephone or videoconference), and Landlord and/or its agents shall receive prior notice of, and shall have the right to attend, all such meetings, and, upon Landlord's request, certain of Tenant's Agents shall attend such meetings. In addition, minutes shall be taken at all such meetings, a copy of which minutes shall be promptly delivered to Landlord. One such meeting each month shall include the review of Contractor's current request for payment.

4.3 Notice of Completion; Copy of "As Built" Plans. Within fifteen (15) days after completion of construction of the Tenant Improvements, Tenant shall cause a Notice of Completion to be recorded in the office of the Recorder of the County in which the 1200 Building is located in accordance with Section 8182 of the Civil Code of the State of California or any successor statute, and shall furnish a copy thereof to Landlord upon such recordation. If Tenant fails to do so, Landlord may execute and file the same on behalf of Tenant as Tenant's agent for such purpose, at Tenant's sole cost and expense. At the conclusion of construction, (i) Tenant shall cause the Architect and Contractor (A) to update the Approved Working Drawings as necessary to reflect all changes made to the Approved Working Drawings during the course of

ACTIVE/117699601.1

construction, (B) to certify in accordance with the standards of professional care of the industry generally applicable to architects that the "record-set" of as-built drawings are true and correct, which certification shall survive the expiration or termination of the Lease, (C) to deliver to Landlord two (2) sets of sepias of such as-built drawings within ninety (90) days following issuance of a certificate of occupancy for the Expansion Space, and (D) to deliver to Landlord a computer disk or other commonly used memory device containing the Approved Working Drawings in AutoCAD format, and (ii) Tenant shall deliver to Landlord a copy of all warranties, guaranties, and operating manuals and information relating to the improvements, equipment, and systems in the Expansion Space.
