Sublessor warrants and represents to Sublessee that, to Sublessor’s current actual knowledge, the Master Lease is in full force and effect and Sublessor is not in default or breach of any of the provisions of the Master Lease, and that Sublessor has no knowledge of any claim by Lessor that Sublessor is in default or breach of any of the provisions of the Master Lease.

Sublessee covenants that it will occupy the Premises in accordance with the terms of the Master Lease as incorporated herein and will not suffer to be done or omit to do any act which may result in a violation of or a default under any of the terms and conditions of the Master Lease, or render Sublessor liable for any damage, charge or expense thereunder. Sublessee warrants and represents that all financial information relating to Sublessee which has been provided to Sublessor is true and correct.

The Term of this Sublease shall commence on July 1, 2020 (the “Commencement Date”) so long as the following have been completed: (i) the full execution and delivery of this Sublease, (ii) receipt of Lessor’s consent to this Sublease (“Lessor Consent”), (iii) payment of the first months’ Base Rent and Security Deposit by Sublessee and (iv) submission by Sublessee of acceptable certificates of insurance naming Lessor and Sublessor.

Sublessee shall not be obligated to pay any Base Rent or Operating Expenses/utilities during the Early Access Period (subject to the last paragraph of this Section 5).

If for any reason Sublessor does not deliver possession to Sublessee on the Commencement Date, the validity of this Sublease shall not be impaired. Notwithstanding the foregoing, if Sublessor has not delivered possession to Sublessee within thirty (30) days after the Commencement Date, then at any time thereafter and before delivery of possession of the Premises to Sublessee, Sublessee may give written notice to Sublessor of Sublessee’s intention to cancel this Sublease. Said notice shall set forth an effective date for such cancellation which shall be at least five (5) business days after delivery of said notice to Sublessor. If Sublessor delivers possession to Sublessee on or before such effective date, this Sublease shall remain in full force and effect. If Sublessor fails to deliver possession to Sublessee on or before such effective date, this Sublease shall be cancelable by Sublessee, in which case all consideration previously paid by Sublessee to Sublessor on account of this Sublease shall be returned to Sublessee (subject to the following paragraph of this section), this Sublease shall thereafter be of no further force or effect, and Sublessor shall have no further liability to Sublessee on account of such delay or cancellation. Sublessee may not cancel this Sublease for any other reason than those contained herein.

Sublessee shall pay to Sublessor concurrently with Sublessee’s execution of this Sublease and Lessor Consent, the sum of $63,425.00 as prepayment of the Base Rent due for January 2021. If the Commencement Date falls on a day other than the first day of a month, the Base Rent for the partial months shall be prorated on a per diem basis based on the actual number of days in the month in which the Commencement Date occurs.

The Sublease Premises may be used for research and development laboratory, related office and other related uses permitted by Applicable Laws, including zoning ordinances, and the Master Lease. Sublessee shall not commit or allow to be committed any waste upon the Premises, or any public or private nuisance or act which is unlawful.

Sublessee shall accept the Premises in its “as-is” condition. Note that Sublessor has not occupied the Premises and will deliver in same condition as Sublessor has received from Landlord on June 15, 2020 which is the commencement date of Master Lease. For any repair, maintenance or replacement of Building Systems performed by Lessor, Sublessee

will pay Sublessee’s Pro Rata Share of such costs in the same manner as provided under the Master Lease.

Sublessee agrees that Sublessor shall not be required to perform any of the covenants, agreements and/or obligations of Lessor under the Master Lease and, insofar as any of the covenants, agreements and obligations of Sublessor hereunder are required to be performed under the Master Lease by Lessor thereunder, Sublessee acknowledges and agrees that Sublessee will look solely to Lessor for such performance. Sublessor shall not be responsible for any failure or interruption, for any reason whatsoever, of the services, utilities or facilities that may be appurtenant or supplied to the Premises by Lessor or otherwise and no such failure will in any way excuse Sublessee’s performance under this Sublease or entitle Sublessee to any abatement of rent or other charge, except as may be expressly permitted by the terms of the Master Lease. Sublessee shall pay to Sublessor as Rent hereunder any and all sums which Sublessor may be required to pay Lessor arising out of a request by Sublessee for additional building services or any other services from Lessor, and which Lessor bills to Sublessor.

Subject to the Master Lease, casualty and Force Majeure events, Sublessee shall have 24/7 access to and use of the Premises.

Sublessee shall not assign, mortgage, encumber or otherwise transfer this Sublease or sublet the whole or any part of the Premises without the prior written consent of Lessor and Sublessor (Sublessor’s consent not to be unreasonably withheld, conditioned or delayed) and any such transfer will be subject to compliance with all terms and conditions of the Master Lease. No assignment, subletting or other transfer shall relieve Sublessee of any liability under this Sublease. Consent to any such assignment, subletting or transfer shall not operate as a waiver of the necessity for consent to any subsequent assignment, subletting or transfer. In connection with each request for an assignment or subletting, Sublessee shall pay the reasonable cost of processing such assignment or subletting, including attorneys’ fees, and any fees or costs payable under the Master Lease, within fifteen (15) days after demand by Sublessor.

All applicable terms and conditions of the Master Lease are incorporated into and made a part of this Sublease as if Sublessor were the lessor thereunder (provided that under no circumstance shall Sublessor be responsible or liable in any way for the failure of the Lessor to perform any acts required under the Master Lease or to supply any item, including, but not limited to, any utility or service to the subleased Premises and no such failure will in any way excuse Sublessee’s performance under this Sublease or entitle Sublessee to any abatement of rent or other charge, except as may be expressly permitted by the terms of the Master Lease), Sublessee the lessee thereunder, and the Premises the Master Premises, except for the following: All sections of the summary except the definitions of Building, Premises, Project, Rentable Area of Premises, Rentable Area of Building and Rentable Area of Project and Permitted Use, the first and second paragraphs of Section 2, Section 4, Sections 38, 40, 43, 44 and Exhibit I of the Master Lease. Sublessee assumes and agrees to perform the lessee’s obligations under the Master Lease during the Term to the extent that such obligations are applicable to the Premises, except that the obligation to pay Rent to Lessor under the Master Lease shall be considered performed by Sublessee to the extent and in the amount rent is paid to Sublessor in accordance with Section 6 of this Sublease.

Sublessor shall not enter into a voluntary termination of the Master Lease as to the Sublease Premises without Sublessee’s prior consent, not to be unreasonably withheld. Notwithstanding the foregoing, Sublessor may assign or transfer the Master Lease without the consent of Sublessee and from and after the effective date of such transfer or assignment, Sublessee will look solely to such transferee or assignee for the performance of the obligation of Sublessor hereunder and Sublessor shall be released on all further obligations under this Sublease. If the Master Lease gives Sublessor any right to terminate the Master Lease in the event of the partial or total damage, destruction, or condemnation of the Master Premises or the building or project of which the Master Premises are a part, the exercise of such right by Sublessor shall not constitute a default or breach hereunder. If the Master Lease terminates for any reason (other than a default by Sublessor under the Master Lease), this Sublease will terminate on the same date as the Master Lease, and Sublessor will have no liability to Sublessee on account of such termination. In all provisions of the Master Lease requiring tenant to submit, exhibit to, supply or provide Lessor with evidence, certificates, or any other matter or thing, Sublessee shall be required to submit, exhibit to, supply or provide, as the case may be, the same to both Lessor and Sublessor.

If any action or proceeding is brought against Lessor or Sublessor by reason of any of the foregoing matters, Sublessee shall upon notice defend the same at Sublessee’s expense by counsel reasonably satisfactory to Lessor and Sublessor, and Sublessor shall cooperate with Sublessee in such defense. Sublessor will indemnify Sublessee for Sublessor’s breach of Sublessor’s obligations under the Master Lease to the extent such breach was not caused or contributed to by Sublessee, its agents or employees. Nothing in this section shall be deemed to affect Sublessor’s right to indemnification for liability or liabilities arising prior to termination of this Sublease for personal injury or property damage under any other indemnification or other provision of this Sublease.

6

account of the indemnifying party’s dealings with any real estate broker or agent other than the Broker. The foregoing indemnity shall survive this Sublease. Sublessor will pay a commission to the Broker on account of this Sublease pursuant to a separate written agreement.

Copies of all notices and demands by the Lessor to either party alleging any default under the terms of the Master Lease or this Sublease shall be promptly provided to the other party. In all provisions of the Master Lease requiring that the tenant thereunder deliver notice to Lessor, Sublessee shall be required to deliver notice concurrently to Sublessor and Lessor.

Whenever the consent of Sublessor is required pursuant to the terms of this Sublease, including, without limitation, the terms of the Master Lease incorporated herein by reference, such consent shall not be unreasonably withheld, conditioned or delayed; provided that whenever Lessor’s consent to such request is also required pursuant to this Sublease or the Master Lease, (i) it shall be reasonable for Sublessor to withhold its consent if Lessor withholds its consent, (ii) it shall be reasonable for Sublessor to delay its consent or withholding of such consent until such time as Lessor has given or denied its consent, (iii) it shall be reasonable for Sublessor to condition its consent upon any conditions imposed by Lessor upon Lessor’s consent, and (iv) Sublessor shall not be liable for or subject to a suit for specific performance based on Sublessor’s withholding, conditioning or delaying of consent caused by Lessor withholding, conditioning or delaying its consent to the same request.

This Sublease is subject to and contingent upon Lessor’s execution of a Consent to Sublease in a form reasonably acceptable to Sublessor and Sublessee within thirty (30) days of the date hereof. In the event Lessor does not so execute such Consent to Sublease within such time, either party may terminate this Sublease upon written notice to the other party, which termination will be effective upon receipt.

Sublessee acknowledges the provisions of the Master Lease disclosing certain Pre-Existing Hazardous Materials and the Contemplated Covenant (both as defined in the Master Lease), and agrees that Lessor shall be solely responsible for such items and Sublessee shall not look to Sublessor in connection with such items. Sublessee hereby waives and releases Sublessor from any and all Claims relating to the Pre-Existing Hazardous Materials and the Contemplated Covenant. If Sublessee knows, or has reasonable cause to believe, that a Hazardous Material has come to be located in, on, under or about the Premises in violation of applicable laws or the Master Lease, Sublessee shall immediately give written notice of such fact to Sublessor, and provide Sublessor with a copy of any report, notice, claim or other documentation which Sublessee has concerning the presence of such Hazardous Material. Upon the expiration of the Term of this Sublease, Sublessee will prepare a Surrender Plan (which will be subject to the approval of Lessor and Sublessor) and return the Premises to Sublessor free of any residual Hazardous Materials resulting from Sublessee’s use and occupancy of the Premises. Nothing in this Section 23 is intended to or will be construed to impose any liability on Sublessee for any violation of the terms of the Master Lease applicable to Hazardous Material which violation is caused solely by Sublessor, its agents or employees.

The occurrence of any of the following events (each, an “Event of Default”) shall constitute a material default and breach of this Sublease by Sublessee: (a) a default under the Master Lease due to Sublessee’s acts or omissions; (b) the breach of any of the provisions of Article 20 of the Master Lease.    Upon any Event of Default under this Sublease, Sublessor shall have all of the remedies available to Lessor pursuant to the Master Lease, including without limitation the remedies enumerated in Article 21 of the Master Lease. All rights and remedies of Sublessor herein enumerated or incorporated by reference above shall be cumulative, and none shall exclude any other right or remedy allowed by law or in equity,
