*Provided that Subtenant is not in default beyond applicable notice and cure periods of the terms and conditions of this Sublease, Sublandlord agrees to abate the obligation of Subtenant to pay Base Rent for months 7-18 of the Term (the “Conditional Rent”).   Notwithstanding the foregoing, however, during such abatement period, Subtenant shall be responsible for the payment of all Additional Rent allocable to the Premises then subleased hereunder.  In the event of a default by Subtenant beyond any applicable notice and cure periods and the expiration or earlier termination of this Sublease, Sublandlord shall be entitled to recover the unamortized portion of the Conditional Rent (i.e., the unamortized portion of the Conditional Rent shall be deemed not to have been abated, and shall become immediately due and payable as unpaid Rent earned, but due at the time of such default).      

*The above chart assumes that the Expansion Premises Commencement Date occurs on the first day of the twenty-fifth (25th) month of the Term of this Sublease. If the Expansion Premises Commencement Date occurs on an earlier or later date, the above chart shall be deemed adjusted to provide for Subtenant to pay Base Rent on the increased square footage commencing on the Expansion Premises Commencement Date only.

Base Rent and Additional Rent shall be paid to Sublandlord without demand, deduction, set-off or counterclaim, in advance on the first day of each calendar month during the Term of this Sublease, and in the event of a partial rental month, Base Rent and Additional Rent shall be prorated on the basis of a 365-day year.  If Base Rent or Additional Rent abates under the Master Lease as to a portion of the Premises as to which this Sublease has commenced, Base Rent or Additional Rent, as the case may be, shall abate on a pro-rata basis under this Sublease.  If Sublandlord does not deliver the Lab Space to Subtenant in the required condition on or before December 31, 2020, Subtenant shall be entitled to a day-for-day credit in its Base Rent and Additional Rent obligations (calculated on a pro-rata rentable square foot basis) for the period commencing on January 1, 2021 and ending on the date on which Sublandlord delivers the Lab Space to Subtenant in the required condition.    

3.2Operating Costs And Expenses.

3.2.1Subtenant shall pay to Sublandlord as additional rent hereunder Subtenant’s pro rata share of (i) Tenant’s Share of Direct Expenses (as defined in the Master Lease) payable by Sublandlord under the Master Lease, and (ii) utilities (including any applicable taxes thereon) contracted through Sublandlord.  Subtenant’s pro rata share shall mean that amount, expressed as a percentage, equal to the number of square feet included in the Premises then subleased by Subtenant divided by the number of square feet leased by Sublandlord under the Master Lease (i.e., 74.27% prior to the prior to the Expansion Premises Commencement Date, and 100% after the Expansion Premises Commencement Date).  Such amounts of Direct Expenses shall be payable in advance on the first day of each calendar month during the Term of this Sublease in accordance with Article 4 of the Master Lease.  Sublandlord shall promptly forward all Estimate Statements, Statements, invoices and backup documentation received from Master Landlord regarding Tenant’s Share of Direct Expenses.  Subtenant shall be entitled to all credits,

if any, given by Master Landlord to Sublandlord for Sublandlord’s overpayment of any amounts under the Master Lease to the extent allocable to the portion of the Premises as to which this Sublease has commenced and to the extent paid by Subtenant.  

In the event that the Term shall expire or earlier terminate on any date other than December 31, Subtenant’s obligations under this Section 3.2.1 for such calendar year shall be prorated on the basis of the number of days elapsed during such calendar year prior to and including the date of expiration or termination.

3.2.3Any and all amounts paid by Sublandlord under the Master Lease for Direct Expenses shall be conclusively deemed to be accurate and binding upon Subtenant for purposes of interpretation of this Section 3, subject to Subtenant’s right to require Sublandlord to perform an audit, at Subtenant’s expense, pursuant to Section 4.6 of the Master Lease, which Sublandlord shall do promptly upon request by Subtenant and Sublandlord shall promptly share the results of such audit with Subtenant.  All forms of Additional Rent and any other amounts payable by Subtenant to Sublandlord shall be payable by Subtenant without deduction, offset or abatement (except as expressly set forth in this Sublease or the provisions of the Master Lease incorporated herein) in lawful money of the United States to Sublandlord at such places and to such persons as Sublandlord may direct.  All such amounts, together with Base Rent, are collectively referred to herein as “Rent.”  

3.2.4If Subtenant fails to pay any installment or other payment of rent to Sublandlord when due, such unpaid amount shall be subject to late charges and shall bear interest in accordance with Article 25 of the Master Lease, as incorporated herein.  All interest and late charges accrued under this Section shall be deemed to be Additional Rent payable hereunder.

If Subtenant shall default in the performance of any of its obligations under this Sublease, other than its obligation to pay Rent to Sublandlord, Sublandlord, without being under any obligation to do so and without thereby waiving such default, may remedy such default for the account and at the expense of Subtenant, without notice in a case of emergency and, in all other cases, if the default continues after three (3) days from the date of written notice thereof from Sublandlord.

9.1.5With respect to any approval or consent required to be obtained from Master Landlord under the Master Lease, such approval or consent must be obtained from Master Landlord and Sublandlord, and the approval or consent of Sublandlord may be withheld if Master Landlord’s approval or consent is not obtained.  Such approvals and consents shall include, without limitation, all approvals and consents required with respect to Hazardous Materials and Transfers.

9.4Surrender.  Subtenant shall surrender the Premises to Sublandlord broom- clean and in as good a condition as on the Initial Premises Commencement Date or Expansion Premises Commencement Date, as applicable, ordinary wear and tear, casualty and condemnation excepted, and free of Hazardous Materials caused by Subtenant to the extent required under the Master Lease.  Prior to expiration or earlier termination of this Sublease, Subtenant shall (a) remove any Alterations, additions and improvements made by or at the request of Subtenant (whether or not made with Sublandlord’s consent) to the extent required by Master Landlord, (b) remove all Subtenant’s trade fixtures, equipment and personal property, and (c) restore the Premises to the condition described in the first sentence of this section, all at Subtenant’s expense. In addition, and without limiting the foregoing, it is expressly agreed that Subtenant shall be obligated to remove any Alterations or any additions and improvements made by or at the request of Sublandlord as “Tenant” under the Master Lease (whether or not made with Master Landlord’s participation of consent) or otherwise existing in the Premises on the Initial Premises Commencement Date to the extent required by Master Landlord.  If the Premises are not so surrendered, then Subtenant shall be liable to Sublandlord for all cost incurred by Sublandlord (including any charges by Master Landlord under the Master Lease) in returning the Premises to such required condition, plus interest thereon at the rate of ten percent (10%) per annum.    

9.5Hazardous Materials.  Subtenant shall use no Hazardous Materials in, on, under or about the Premises or the Building, except as permitted by Section 5.3 of the Master Lease, as incorporated therein.  Subject to receipt of Master Landlord’s consent, Sublandlord hereby approves of Subtenant’s use of the Hazardous Materials on the form attached hereto as Exhibit D.  Subtenant hereby agrees that the obligations of “Tenant”  in Section 5.3 of the Master Lease are incorporated herein by reference as specified above, including without limitation all such obligations to deliver Environmental Questionnaires (including the delivery of an Environmental Questionnaire concurrently with the execution and delivery of this Sublease), and all obligations to deliver notices, notifications, certifications, documents, environmental assessments, Environmental Reports, and Clean-up plans.  In addition, Subtenant specifically acknowledges that Sublandlord shall have the obligation, and the right, to deliver all such Environmental Questionnaires and other documents and notices to Master Landlord in fulfillment of Sublandlord’s obligations to Master Landlord under the Master Lease.  Sublandlord agrees to use reasonable commercial efforts to minimize the creation of duplicative or inconsistent obligations to Master Landlord and Sublandlord under Sections 5.3.1.3(iii) and (iv), 5.3.2 and 5.3.4 of the Master Lease, but nothing herein shall be construed as any waiver by Sublandlord or its rights and remedies pursuant to said Sections of the Master Lease, as incorporated herein.  In Section 5.3.1.4.3, as incorporated by reference herein, the phrase “that exist in, on or about the Project as of the date hereof” shall be deleted and the following phrase shall be inserted in its place:  “that exist in the Premises as of the Initial Premises Commencement Date or the Expansion Premises Commencement Date, as the case may be, and that are caused by Sublandlord and not the obligation of Master Landlord under Section 5.1.4.1.3 of the Master Lease or a third party.”    

9.6Entry By Sublandlord.  Sublandlord shall have the right to enter the Premises as set forth in Article 27 of the Master Lease as incorporated by reference herein, and shall also have the right to use the Common Areas, for purposes of performing its obligations under the Master Lease or this Sublease.

10.2Assignment, Subletting and Encumbrance.  Subtenant shall not voluntarily or involuntarily, by operation of law or otherwise, assign, sublet, mortgage or otherwise encumber all or any portion of its interest in this Sublease or in the Premises without obtaining the prior written consent of Sublandlord and Master Landlord with respect thereto, to the extent such consent is required under the terms and conditions of the Master Lease, as incorporated herein.  If Master Landlord’s consent is obtained, Sublandlord shall not unreasonably withhold its consent to any proposed sublease; provided, however, that Sublandlord may require as a condition of granting any such consent that (a) Subtenant provides to Sublandlord reasonably sufficient evidence of such sublessee’s financial capability, (b) Subtenant reaffirms, in form satisfactory to Sublandlord, its continuing liability under the Sublease.  Any assignment, subletting, mortgage or other

14


 

encumbrance attempted by Subtenant to which Sublandlord and/or Master Landlord has not consented in writing pursuant to the provisions hereof (where such consent was required) shall be null and void and of no effect.  Notwithstanding anything to the contrary in this Sublease, Sublandlord shall have no option to recapture any Contemplated Transfer Space of Subtenant, as set forth in Section 14.4 of the Master Lease.  

10.3Alterations and Improvements By Subtenant.  Subtenant shall not make any to the Premises without first (a) obtaining the written approval of such Alterations from each of Master Landlord and Sublandlord to the extent approval is required under the Master Lease and (b) otherwise complying with all provisions of the Master Lease, as incorporated herein, applicable to such Alterations; provided, however, approval by Sublandlord shall not be required if Master Landlord provides its approval. All such Alterations shall be constructed only after necessary permits, licenses and approvals have been obtained from appropriate governmental agencies and all improvements shall be constructed as to conform to all relevant codes, regulations, and ordinances.  All such Alterations shall be made at Subtenant’s sole cost and shall be diligently prosecuted to completion.  Upon the expiration of this Sublease, Subtenant shall comply with Article 15 of the Master Lease, as incorporated herein, except to the extent that Master Landlord waives such requirement in writing.  Subtenant shall permit no mechanics’ or other liens to be recorded against the Premises related to work performed by or for  Subtenant or anyone claiming by, under or through Subtenant.  Should such a lien be made or filed against the Premises or real property on which the Premises are situated, Subtenant at its sole cost, shall bond against or discharge said lien within thirty (30) days after Sublandlord’s or Master Landlord’s request to do so.  Sublandlord acknowledges that Subtenant plans to install its own security system for the Premises and make the alterations described in Exhibit E, provided Master Landlord consents to the same and does not require that they be restored.  Sublandlord’s contingent waiver of its approval right to Subtenant’s Alterations shall not affect or diminish any of Subtenant’s other obligations to Sublandlord under Section 8 of the Master Lease as incorporated herein, and Subtenant shall provide to Sublandlord all notices, lien waivers, and “as built” drawings and other items required to be delivered to Sublandlord pursuant to that Section.  In addition, to the extent Subtenant is delayed in completing its initial alterations to the Premises due to (i) delays by Sublandlord, but only if the delay continues for two (2) business days after Subtenant’s delivery of a second request for approval in compliance with the notice provisions of this Sublease, which second request must be in writing or sent by email to Sublandlord’s email address provided under Section 10.1 above or (ii) mandatory construction work stoppages imposed by governmental entities in response to the COVID-19 pandemic (by statute, orders or other restrictions), Subtenant shall be entitled to abate one (1) day of rent next coming due with respect to the applicable phase of the Premises for each day of such delay.  

10.4Holding Over.  Any holdover by Subtenant shall be governed by Article 16 of the Master Lease, as incorporated herein by reference.  In addition, Sublandlord expressly reserves the right to require Subtenant to surrender possession of the Premises upon the expiration of the Term or upon the earlier termination hereof and the right to assert any remedy at law or in equity to evict Subtenant and/or collect damages in connection with any such holding over, and Subtenant shall indemnify, defend and hold Sublandlord harmless from and against any and all claims, demands, actions, losses, damages, obligations, costs and expenses, including, without limitation, attorneys’ fees incurred or suffered by Sublandlord by reason of Subtenant’s failure to surrender the Premises on the expiration or earlier termination of this Sublease in accordance with

15


 

the provisions of this Sublease, as set forth in the final sentence of such Article 16 of the Master Lease; provided, however, the holdover rent paid by Subtenant hereunder shall be credited against all such claims, demands, actions, losses, damages, obligations, costs and expenses.    

10.5Waiver.  The waiver of Sublandlord or Subtenant of any agreement, condition or provision contained herein or any provision incorporated herein by reference shall not be deemed to be a waiver of any subsequent breach of the same or any other agreement, condition or provision, nor shall any custom or practice which may evolve between the parties in the administration of the terms hereof be construed to waive or to lessen the right of Sublandlord or Subtenant to insist upon the performance by the other in strict accordance with said terms.  The subsequent acceptance of Rent hereunder by Sublandlord shall not be deemed to be a waiver of any preceding breach by Subtenant of any agreement or condition of this Sublease or the same incorporated herein by reference, other than the failure of Subtenant to pay the particular Rent so accepted, regardless of Sublandlord’s knowledge of such preceding breach at the time of acceptance of such Rent.

10.6Complete Agreement.  There are no oral agreements between Sublandlord and Subtenant affecting this Sublease, and this Sublease supersedes and cancels any and all previous negotiations, letters of intent, brochures, agreements and understandings, if any, between Sublandlord and Subtenant or displayed by Sublandlord, its agents or real estate brokers to Subtenant with respect to the subject matter of this Sublease, the Premises or the Building.  There are no representations between Sublandlord and Subtenant other than those contained in or incorporated by reference into this Sublease.

10.7Insurance.  Subtenant shall comply with the insurance provisions applicable to Tenant under the Master Lease, as incorporated herein.  Such insurance shall insure the performance by Subtenant of its applicable obligations hereunder and the liability insurance shall name Master Landlord and Sublandlord as additional insureds.   All such insurance shall include an endorsement requiring thirty (30) days written notice from the insurance company to Master Landlord and Sublandlord before cancellation or change in coverage, insureds or amount of policy.  Subtenant shall provide both Master Landlord and Sublandlord with certificates of insurance evidencing such coverage prior to the earlier of entry into the Premises or the commencement of this Sublease.   The waiver of subrogation provision contained in Section 10.5 of the Master Lease shall be deemed to be a three-party agreement binding among and inuring to the benefit of Sublandlord, Subtenant and Master Landlord (by reason of its consent hereto).

11.Indemnification; Exculpation

11.1Non-Liability Of Sublandlord.  Sublandlord shall not be liable to Subtenant, and Subtenant hereby waives and releases all claims against Sublandlord and its partners, officers, directors, employees, trustees, successors, assigns, agents, servants, affiliates, representatives, and contractors (collectively, herein “Sublandlord Affiliates”) for injury or damage to any person or property occurring or incurred in connection with, or in any way relating to, the Premises.  Without limiting the foregoing, neither Sublandlord nor any of the Sublandlord Affiliates shall be liable for and there shall be no abatement of Rent for (i) any damage to Subtenant’s property stored with or entrusted to Sublandlord or Sublandlord Affiliates, (ii) loss of or damage to any property by theft or any other wrongful or illegal act, or (iii) any injury or damage
