The Expansion Space A Allowance and the Space A HVAC Allowance shall be payable as provided below. In no event shall the Expansion Space A, Allowance and the Space A HVAC Allowance be used to reimburse any costs of designing, procuring or installing in Expansion Space A any trade fixtures, movable equipment, furniture, furnishings, telephone equipment, cabling for any of the foregoing, or other personal property (collectively “Personal Property” for purposes of this Amendment), and the cost of such Personal Property shall be paid by Tenant. Notwithstanding the foregoing, Landlord agrees that lab specific improvements, including, without limitation, fixed benches and hoods, shall not be considered to be the Personal Property of Tenant, and Landlord agrees that the costs of the same shall be included within the definition of the Permanent Improvement Costs.

4

balance remaining thereafter shall be retained by Landlord as its sole property and Landlord shall have no obligation or liability to Tenant with respect to such excess. Landlord will bid out the work for the replacement of the Building 27 roof (the “Building 27 Roof”) and select a contractor that will be hired by Tenant’s general contractor. Tenant shall be responsible for the replacement of the Building 27 Roof and Landlord will reimburse Tenant for the costs of such replacement after Landlord receipt of the items (i) through (iv) described above but with respect to the Building 27 Roof. Landlord shall be entitled to a construction administration fee described above with respect to the Building 27 Roof.

Under such circumstances the ESACD and rent with respect to Expansion Space A shall not commence until Expansion Space A is made available to Tenant by Landlord, and no such failure to give possession on the estimated Expansion Space A Commencement Date shall affect the validity of this Amendment, the Existing Lease or the obligations of the Tenant under either.

Except as set forth below: (i) Landlord shall deliver Expansion Space C to Tenant in its AS IS condition, without any express or implied representations or warranties of any kind by Landlord, its brokers, manager or agents, or the employees of any of them regarding Expansion Space C; and (ii) Landlord shall not have any obligation to construct or install any tenant improvements or alterations or to pay for any such construction or installation. Notwithstanding the foregoing, Tenant shall notify Landlord in writing within forty‐five (45) days after Tenant takes possession of Expansion Space C of any defects in the base Building electrical, heating, ventilation and air conditioning and plumbing systems located in or exclusively serving Expansion Space C (“Expansion Space C Defects”). Except for Expansion Space C Defects stated in such notice, Tenant shall be conclusively deemed to have accepted Expansion Space C “AS IS” in the condition existing on the date Tenant first takes possession, and to have waived all claims relating to the condition of Expansion Space C. Landlord shall proceed diligently to correct the Expansion Space C Defects stated in such notice unless Landlord disputes the existence of any such Expansion Space C Defects. In the event of any dispute as to the existence of any such defects, the reasonable decision of Landlord shall be final and binding on the parties. No agreement of Landlord to alter, remodel, decorate, clean or improve Expansion Space C or the real property and no representation regarding the condition of Expansion Space C or the real property has been made by or on behalf of Landlord to Tenant, except as may be specifically stated in this Amendment.
(2)    Commencement Date; Term. The Expansion Space C Commencement Date (“ESCCD”) shall mean the date which is one hundred eighty (180) days after the date on which Landlord delivers possession of Expansion Space C to Tenant for occupancy (which delivery is estimated to be October 16, 2017) and, upon the ESCCD (which is estimated to be April 16, 2018), Expansion Space C becomes a part of the Premises, and Tenant’s obligation to pay rent commences with respect to Expansion Space C. The Term of this lease of Expansion Space C (the “Space C Term”) shall continue until the Phase 1 Termination Date. Within thirty (30) days after request by 

11

Landlord, Tenant and Landlord shall enter into an agreement confirming the ESCCD and the Monthly Base Rent substantially in the form of Exhibit B attached hereto. If Tenant fails to enter into such agreement within ten (10) days following Landlord’s delivery of written notice of such failure to Tenant, then the ESCCD shall be the date designated by Landlord in such agreement.
(3)    Expansion Space C Tenant Alterations & Allowance. All design and construction of any alterations, additions, improvements, installations or refurbishment of permanent improvements to Expansion Space C (“Expansion Space C Tenant Alterations”) shall be performed by Tenant pursuant to the provisions of Article Nine of the Existing Lease. Notwithstanding any provisions of the Existing Lease to the contrary, Landlord shall provide an allowance equal to Four Hundred Twenty‐Seven Thousand One Hundred Eighty‐Five and 00/100 Dollars ($427,185.00) (the “Expansion Space C Allowance”), which may be applied to the costs of “Permanent Improvement Costs” in Expansion Space C, including Landlord’s construction administration fee not to exceed one percent (1%) of the Expansion Space C Allowance and the Space C HVAC Allowance (it is agreed that such 1% construction administration fee shall be in lieu of, and not in addition to, the 3% construction administration fee provided in Article Nine of the Existing Lease). Additionally, and specifically related to the replacement of the agreed upon HVAC units serving Expansion Space C, Landlord shall provide Tenant with an allowance equal to One Hundred Forty‐Five Thousand and 00/100 Dollars ($145,000.00) (the “Space C HVAC Allowance”), which Space C HVAC Allowance shall be added to, and in addition to, the Expansion Space C Allowance, and which Space C HVAC Allowance shall be used by Tenant to replace all or any of the HVAC units serving Expansion Space C. Tenant shall utilize the Space C HVAC Allowance solely for the purchase, installation and replacement of the HVAC units serving Expansion Space C (the “Space C HVAC Improvements”). The Space C HVAC Allowance shall not be used for the repair of any existing HVAC units. Prior to commencing the Space C HVAC Improvements, Tenant shall provide Landlord with a copy of the contract for such Space C HVAC Improvements and obtain Landlord’s approval of such contract (such approval by Landlord shall not be unreasonably withheld). Landlord shall have the right to have its property manager supervise the Space C HVAC Improvements. The Expansion Space C Allowance and the Space C HVAC Allowance shall be payable as provided below. In no event shall the Expansion Space C Allowance and the Space C HVAC Allowance be used to reimburse for any costs of designing, procuring or installing in Expansion Space C any Personal Property, and the cost of such Personal Property shall be paid by Tenant. The Expansion Space C Allowance and the Space C HVAC Allowance shall be paid to Tenant within thirty (30) days after the later of final completion of the Expansion Space C Tenant Alterations and the Space C HVAC Improvements, respectively, and Landlord’s receipt of (i) a certificate of occupancy (if applicable), (ii) final as‐built plans and specifications, (iii) full, final, unconditional lien releases, and (iv) reasonable substantiation of costs incurred by Tenant with respect to the Expansion Space C Tenant Alterations and the Space C HVAC Improvements, respectively, but in no event shall Landlord be obligated to make such payment until after the ESCCD. Tenant must prior to the date which is twelve (12) months after the ESCCD, submit written application with the items required above for disbursement or reimbursement for any reimbursable costs out of the Expansion Space C Allowance and the Space C HVAC Allowance, respectively, 

12

and to the extent of any funds for which application has not been made prior to that date or if and to the extent that the reimbursable costs of the Expansion Space C Tenant Alterations and the Space C HVAC Improvements, respectively, are less than the amount of the Expansion Space C Allowance and the Space C HVAC Allowance, respectively, any balance remaining thereafter shall be retained by Landlord as its sole property and Landlord shall have no obligation or liability to Tenant with respect to such excess. Landlord agrees that, so long as the Expansion Space C Tenant Alterations are in substantial accordance with the improvements plans provided to and approved by Landlord prior to the execution of this Amendment, Tenant shall have no obligation to restore any portion of the Expansion Space C Tenant Alterations at or prior to the Phase 1 Termination Date; provided, however, regardless of the foregoing, in any event, Tenant shall remove any Expansion Space C Tenant Alterations containing Hazardous Material and all Tenant’s trade fixtures, and, subject to Section 6.03 of the Original Lease, cabling and wiring installed for Tenant’s personal property or trade fixtures.
(4)    Delayed or Early Delivery of Possession. If Landlord shall be unable to give possession of Expansion Space C on the estimated Expansion Space C Commencement Date by reason of the following: (i) the holding over or retention of possession of any tenant, tenants or occupants, or (ii) for any other reason, then Landlord shall not be subject to any liability for the failure to give possession on said date. Under such circumstances the ESCCD and rent with respect to Expansion Space C shall not commence until Expansion Space C is made available to Tenant by Landlord, and no such failure to give possession on the estimated Expansion Space C Commencement Date shall affect the validity of this Amendment, the Existing Lease or the obligations of the Tenant under either. Notwithstanding any of the foregoing provisions of this Section to the contrary, if Landlord has not tendered possession of Expansion Space C on or before the Space C Sunset Date (defined below), then, as Tenant’s sole and exclusive remedy, Tenant shall have the option to terminate the Lease solely with respect to Expansion Space C exercisable by giving written notice to Landlord within three (3) business days after the Space C Sunset Date. If Tenant does not timely give notice of its election to terminate this Lease as aforesaid and delivery of possession does not occur on or before the date which is thirty (30) days following the Space C Sunset Date, then Tenant shall again have such option to terminate the Lease solely with respect to Expansion Space C in the manner described above and such date shall constitute the new Space C Sunset Date; it being the intention of the parties that Tenant shall have a recurring termination option after each such thirty (30) day period following the initial Space C Sunset Date if Landlord has not tendered possession by the end of each such thirty (30) day period. As used in this Lease, “Space C Sunset Date” means the initial Space C Sunset Date of April 16, 2018, and any succeeding new Space C Sunset Dates (at thirty (30) day intervals after the initial Space C Sunset Date), and each such Space C Sunset Date, as applicable, shall be extended by the number of days of delay due to Force Majeure plus the number of days of Tenant Delay, if any. On or before the Space C Sunset Date, if such date includes any period of Force Majeure or Tenant Delay, Landlord shall give Tenant written notice of the resulting calendar date which is the Space C Sunset Date.

SECTION 20.    OFAC. Landlord advises Tenant hereby that the purpose of this Section is to provide to the Landlord information and assurances to enable Landlord to comply with the law relating to OFAC.
Tenant hereby represents, warrants and covenants to Landlord, either that (i) Tenant is regulated by the SEC, FINRA or the Federal Reserve (a “Regulated Entity”) or (ii) neither Tenant nor any person or entity that directly or indirectly (a) controls Tenant or (b) has an ownership interest in Tenant of twenty‐five percent (25%) or more, appears on the list of Specially Designated Nationals and Blocked Persons (“OFAC List”) published by the Office of Foreign Assets Control (“OFAC”) of the U.S. Department of the Treasury.

Landlord hereby discloses 

24

pursuant to California Civil Code Section 1938 as follows: “A Certified Access Specialist (CASp) can inspect the subject premises and determine whether the subject premises comply with all of the applicable construction‐related accessibility standards under state law. Although state law does not require a CASp inspection of the subject premises, the commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for the CASp inspection, and the cost of making any repairs necessary to correct violations of construction‐related accessibility standards within the premises.” Landlord and Tenant hereby acknowledge and agree that in the event that Tenant elects to perform a CASp inspection of the Premises hereunder (the “Inspection”), such Inspection shall be (a) performed at Tenant’s sole cost and expense, (b) limited to the Premises and (c) performed by a CASp who has been approved or designated by Landlord prior to the Inspection. Any Inspection must be performed in a manner which minimizes the disruption of business activities in the Building, and at a time reasonably approved by Landlord. Landlord reserves the right to be present during the Inspection. Tenant agrees to: (i) promptly provide to Landlord a copy of the report or certification prepared by the CASp inspector upon request (the “Report”), and (ii) keep the information contained in the Report confidential, except to the extent required by Law, or to the extent disclosure is needed in order to complete any necessary modifications or improvements required to comply with all applicable accessibility standards under state or federal Law, as well as any other repairs, upgrades, improvements, modifications or alterations required by the Report or that may be otherwise required to comply with applicable Laws or accessibility requirements (the “Access Improvements”). Unless otherwise the responsibility of Landlord under the express terms of this Amendment, Tenant shall be solely responsible for the cost of Access Improvements to the Premises or the Building necessary to correct any such violations of construction‐related accessibility standards identified by such Inspection as required by Law, which Access Improvements may, at Landlord’s option, be performed in whole or in part by Landlord at Tenant’s expense, payable as Additional Rent within ten (10) days following Landlord’s demand.
SECTION 24.    ENERGY UTILITY USAGE. If Tenant is billed directly by a public utility with respect to Tenant’s energy usage at the Premises, then, upon request, Tenant shall provide monthly energy 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 energy usage with respect to the Premises directly from the applicable utility company.
SECTION 25.    COUNTERPARTS. This Amendment may be executed in duplicates or counterparts, or both, and such duplicates or counterparts together shall constitute but one original of the Amendment, and the signature of any party to any counterpart shall be deemed a signature to, and may be appended to, any other counterpart. Each duplicate and counterpart shall be equally admissible in evidence, and each original shall fully bind each party who has executed it.
