 3. Abatement. 

(a) Provided that there is no Event of Default by Tenant then occurring pursuant to the terms of the Lease beyond all applicable notice and
cure periods, Minimum Annual Rent, but not Tenant’s Proportionate Share of annual Real Estate Taxes and Operating Expenses, shall be abated during the first four (4) calendar months following execution of this Amendment (the
“2021 Abatement Period”) in the amount of $122,541.67 per month (the “2021 Abated Minimum Annual Rent”). Should there occur an Event of Default by Tenant beyond all applicable notice and cure periods during
such 2021 Abatement Period, Landlord shall be entitled to recover from Tenant (in addition to all other rights and remedies available to Landlord) all 2021 Abated Minimum Annual Rent. 

(b) Provided that there is no Event of Default by Tenant then occurring pursuant to the terms of the Lease beyond all applicable notice and
cure periods, Minimum Annual Rent, but not Tenant’s Proportionate Share of annual Real Estate Taxes and Operating Expenses, shall be abated during the months of April, 2023; May, 2023; and June, 2023 (the “2023 Abatement
Period”) in the amount of $174,081.25 per month (the “2023 Abated Minimum Annual Rent”). Should there occur an Event of Default by Tenant beyond all applicable notice and cure periods during such 2023 Abatement Period,
Landlord shall be entitled to recover from Tenant (in addition to all other rights and remedies available to Landlord) all 2023 Abated Minimum Annual Rent. 

4. Additional Rent. Tenant shall continue to pay all Additional Rent, including but not limited to Tenant’s Proportionate Share of
annual Real Estate Taxes and Operating Expenses, at the times and in the manner as set forth in the Lease, subject to adjustments and reconciliation, as set forth in the Lease. 

5. Improvements. 
 (a)
Following execution of this Amendment, Tenant shall enter into one or more construction contracts (each a “Construction Contract”) with Hankin Commercial Construction Company d/b/a Eagleview Commercial Construction Company (the
“Contractor”) as general contractor who shall perform and manage the construction of the alterations and improvements in the Leased Space conforming to the Approved Tenant Improvement Plans, as such term is hereinafter defined (the
“Improvements”). Tenant’s specifications and plans for the Improvements to the Leased Space (the “Improvement Plans”) shall be prepared by Tenant’s architect, which architect shall be subject to the
approval by Landlord, such approval not to be unreasonably withheld, conditioned or delayed. Landlord hereby approves Jacobs Wyper Architects as Tenant’s architect. Such Improvement Plans will be prepared in sufficient detail to permit
Contractor to construct the Improvements, and shall include partition layout (dimensioned), door location and door schedule including hardware, reflected ceiling plan, telephone and electrical outlets with locations (dimensioned), special
electrical, HVAC and/or plumbing work, mechanicals, special loading requirements, such as the location of special equipment, openings in the walls or floors, all necessary sections and details for special equipment and fixtures, and finishes
including, without limitation, carpentry and millwork, floor coverings, wall coverings, color schedules, and any other special finishes. The Improvement Plans shall be prepared in accordance with applicable laws and code requirements and in
accordance with the terms of the Lease (including Sections 8 and 9, as amended). Within ten (10) business days of Landlord’s receipt of the Improvement Plans, Landlord shall notify Tenant as to whether Landlord approves of the Improvement
Plans, which approval shall not be unreasonably withheld, conditioned or delayed. Landlord’s failure to notify Tenant in writing within such ten (10) business day period will constitute Landlord’s approval thereof. Upon approval or
deemed approval by Landlord, the Improvement Plans shall become final and shall not be materially changed without Landlord’s further approval, which shall not be unreasonably withheld, conditioned or delayed, and shall be subject to the same
timeframe for approval and deemed approval as provided above (as finally approved, the “Approved Tenant Improvement Plans”). The parties agree that (i) Contractor is approved as the general contractor, (ii) Tenant shall
have the right to require the use of certain sub-contractors to perform certain specialty work related to the lab improvements in the Leased Space, subject to the approval of Landlord, which approval shall not
be unreasonably withheld, delayed or conditioned; 

  
 2 













 
and (iii) the sub-contractors identified on Exhibit A attached hereto are approved by Landlord and Tenant. Landlord’s consent shall not be
considered to be unreasonably withheld if any such sub-contractor (i) does not have trade references reasonably acceptable to Landlord, (ii) does not maintain insurance as required pursuant to the
terms of the Lease, (iii) does not have the ability to be bonded for the work in an amount of no less than 125% of the total estimated cost of the portion of the Improvement work which such sub-contractor
is performing, or (iv) is not licensed as a contractor in the state/municipality in which the Leased Space is located. Tenant acknowledges the foregoing is not intended to be an exclusive list of the reasons why Landlord may reasonably withhold
its consent to a sub-contractor. 
 (b) Provided that there is no Event of Default by Tenant then
occurring pursuant to the terms of the Lease or this Amendment beyond all applicable notice and cure periods, effective on and after execution of this Amendment, Landlord agrees to contribute the sum of $500,000 (the “2021
Allowance”) to be applied towards the cost of the general fit-out Improvements (i.e., carpet and paint, but specifically excluding any lab improvements), provided that Tenant provides Landlord with
the documentation set forth in Section 5(e) below. 
 (c) Provided that there is no Event of Default by Tenant then occurring pursuant
to the terms of the Lease or this Amendment beyond all applicable notice and cure periods, and that Tenant has paid to Contractor at least $5,000,000 towards construction of the Improvements (which sum may not include any costs or expenses applied
towards equipment or any portion of the 2021 Allowance previously utilized), on and after April 1, 2022, Landlord agrees to contribute (by way of payment directly to Contractor) the sum of $2,000,000 (the “2022 Allowance”) to
be applied towards the cost of the Improvements (including, but not limited to, the cost of preparing design and construction documents and mechanical and electrical plans for the Improvements, the cost of city permits, and for hard costs in
connection with the Improvements), provided that Tenant provides Landlord with the documentation set forth in Section 5(e) below. Notwithstanding the foregoing, Landlord shall not be required to pay to Contractor nor shall Tenant be entitled to
any portion of the 2022 Allowance unless and until the later of the following has occurred (i) April 1, 2022 or (ii) Tenant has paid to Contractor at least $5,000,000 for construction of the Improvements as set forth above. 

(d) Provided that there is no Event of Default by Tenant then occurring pursuant to the terms of the Lease or this Amendment beyond all
applicable notice and cure periods, and that Tenant has paid to Contractor at least an additional $8,000,000 towards construction of the Improvements to the Leased Space (which sum may not include any costs or expenses applied towards equipment nor
any portion of the 2021 Allowance or 2022 Allowance previously utilized), on and after April 1, 2023, Landlord agrees to contribute (by way of payment directly to Contractor) the sum of $3,500,000 (the “2023 Allowance”,
together with the 2021 Allowance and the 2022 Allowance, sometimes hereinafter collectively referred to as the “Allowance”) to be applied towards the cost of the Improvements (including, but not limited to, the cost of preparing
design and construction documents and mechanical and electrical plans for the Improvements, the cost of city permits, and for hard costs in connection with the Improvements), provided that Tenant provides Landlord with the documentation set forth in
Section 5(e) below. Notwithstanding the foregoing, Landlord shall not be required to pay to Contractor nor shall Tenant be entitled to any portion of the 2023 Allowance unless and until the later of the following has occurred
(i) April 1, 2023 or (ii) Tenant has paid to Contractor at least an additional $8,000,000 for construction of the Improvements as set forth above. Notwithstanding satisfaction of the conditions set forth in the prior sentence,
Landlord shall be permitted, in Landlord’s sole but reasonable discretion, to withhold up to $2,500,000 of the 2023 Allowance until such time as Landlord determines that Tenant’s financial strength is adequate to satisfy Tenant’s
monetary obligations under the Lease. 

  
 3 













 (e) Any portion of the Allowance to be applied toward the cost of the Improvements, shall be
paid directly to Contractor within thirty (30) days following receipt by Landlord of (1) receipted bills covering all labor and materials expended and used in the Improvements; (2) full and final/partial waivers of lien (as
appropriate); and (3) the certification of Tenant’s architect and engineer of design that the Improvements have been installed in a good and workmanlike manner in accordance with the approved plans, and in accordance with applicable Laws,
codes and ordinances. The Allowance shall be disbursed in the amount reflected on the receipted bills meeting the requirements above. Notwithstanding anything herein to the contrary, Landlord shall not be obligated to disburse any portion of the
Allowance towards the cost of the Improvements during the continuance of an uncured Event of Default by Tenant under the Lease, and Landlord’s obligation to disburse or apply the Allowance shall only resume when and if such Event of Default is
cured. 
 (f) Tenant shall be responsible for all applicable state sales or use taxes, if any, payable in connection with the Improvements
and/or Allowance. 
 (g) Each Construction Contract shall set forth the Improvements to be completed pursuant to such Construction Contract.
In addition, each Construction Contract shall include a schedule (each a “Schedule”) created by Contractor, Landlord and Tenant (working in good faith) establishing an estimated completion date for the Improvements covered by such
Construction Contract (each a “Target Completion Date”). Contractor shall work diligently and in good faith to complete the Improvements contained in each Construction Contract by the Target Completion Date established on the
Schedule for the specific Construction Contract. With respect to each Construction Contract, Contractor shall be entitled to collect and deduct from the Allowance paid pursuant to such Construction Contract a contractor’s fee in an amount equal
to 7% of the total cost of the Improvements (i.e. the Cost of Work as defined in the then current edition of the AIA Standard Form of Agreement between Owner and Contractor) applicable to the Construction Contract, which Cost of Work shall
specifically exclude any amounts paid towards specialty equipment purchased and installed and warranted by Tenant and any fines or penalties assessed against the project resulting from violations of applicable laws and codes, including without
limitation, OSHA, by Contractor or any of its sub-contractors or suppliers within Contractor’s control. Contractor will cause the construction of the Improvements under each Construction Contract to
commence in accordance with the Schedule and shall Substantially Complete the Improvements on the Schedule on or before the date which is thirty (30) days following the date specified on the Schedule (subject to automatic extension for any
delay cause by Force Majeure or Tenant Delay) (the “Target Date”). In the event that the Improvements for a Construction Contract are not Substantially Complete within thirty (30) days of the Target Date (“Outside
Completion Date”) of such Construction Contract, Contractor’s contractor fee shall be automatically reduced by 1% on the first day following the Outside Completion Date and again, if applicable, by an additional 1% each for thirty
(30) day period thereafter until such Improvements have been Substantially Completed. Notwithstanding anything to the contrary, each Construction Contract and its related Schedule shall be applicable only to those Improvements contained
therein. 
 (h) As used herein, (i) “Force Majeure” shall mean matters outside of Contractor’s reasonable control
including, but not limited to the following: strikes, lockout, or labor disputes; failure or interruption of or delay in the availability of any one or more public utilities at the Building for the use of Contractor or its sub-contractors; delays due to governmental regulation or actions or inaction of local, state or federal governments [including, without limitation, any extraordinary delays in issuing building permits, certificates
of occupancy or other similar permits or certificates]; riots, acts of the public enemy, war, invasion, insurrection, mob violence, sabotage or malicious mischief; storm, flood, unusually severe weather or acts of God; fire, explosion, or casualty;
inability to procure, or general shortages of, labor, equipment, facilities, materials or supplies; failure of transportation, epidemics, quarantine restrictions, freight embargoes, or any other cause event or circumstance, whether similar or
dissimilar, beyond Contractor’s control; (ii) “Substantially Complete”, “Substantial Completion” or words of similar import shall mean that any work to be performed by Contractor pursuant to a specific
Construction Contract has 

  
 4 













 
been completed in accordance with the Approved Tenant Improvement Plans, but for minor or insubstantial details of construction, mechanical adjustment or decoration (the absence of which will not
unreasonably interfere with the conduct of business in the Leased Space), and (iii) “Tenant Delay” shall mean any act or omission by Tenant or its agents, employees, invitees or contractors which delays the performance of the
Improvements, including but not limited to (1) any failure by Tenant to submit plans or other deliverables when due, (2) any failure or unreasonable delay by Tenant in supplying information or giving authorizations or approvals,
(3) any delays resulting from changes made by or requested by Tenant to the Approved Tenant Improvement Plans for the Improvements, (4) any delays resulting from the performance of any work by or on behalf of Tenant (other than work
performed on behalf of Tenant by the Contractor), (5) any delays resulting from non-compliance with Tenant’s obligations required by the Lease, and (6) any delays resulting from the performance of
any portion of the Improvements which, by its nature, may require a longer period for construction and completion than do standard finishes, whether by reason of delays in Landlord’s receipt of specially ordered or fabricated materials selected
by Tenant or the intricacies and/or time consuming nature of actually performing the work or otherwise; provided, however, that any such delays shall only be considered a Tenant Delay if Landlord notifies Tenant that Landlord is unable to obtain
such long lead-time or specially ordered or fabricated items in a timely manner and Tenant elects to proceed with said item. If Contractor is delayed in the performance of the Tenant Improvements as a result of a Tenant Delay, the Improvements shall
be deemed to be Substantially Complete on the date that the Improvements could reasonably have been expected to be Substantially Completed absent such Tenant Delay. 

(i) Notwithstanding anything to the contrary contained herein, upon completion of any Improvements, such Improvements (specifically excluding
any equipment installed as part of the lab improvements) shall be deemed the Property of Landlord for purposes of depreciation and otherwise. 

(j) At all times and in addition to any and all other terms of the Lease, Landlord and Tenant will each use all commercially reasonable
efforts to, and to have its respective consultants and contractors, coordinate with each other and the consultants and contractors of the other, and to maintain a ready dialogue and flow of information in a timely manner according to the committed
delivery and completion dates set forth in this Lease. 
 6. Roof Improvements. Landlord, at Landlord’s cost and expense, shall
replace the existing roof of the Building with a new roof of substantially similar quality. Landlord and Tenant acknowledge that because of the nature of Tenant’s use of the Leased Space and the complexities of the installations related to the
lab improvements, the roof replacement shall be performed by Landlord in up to three (3) phases (each a “Roof Phase”). Each Roof Phase shall be installed in accordance with a mutually agreed upon schedule created by Landlord,
Contractor and Tenant working in good faith to avoid interference with the construction of the Improvements. In the event that Tenant or any contractor engaged by or on behalf of Tenant (other than Contractor) damages any portion of the roof in the
performance of the Improvements or otherwise, Tenant shall be responsible for any costs or expenses incurred by Landlord to repair such damage and shall reimburse Landlord for such costs upon written demand from Landlord. 

7. Options to Extend. 

(a) Provided that Landlord has not given Tenant notice of default more than two (2) times following the date of execution of this
Amendment, and there then exists no Event of Default by Tenant under the Lease nor any event that with the giving of notice and/or the passage of time would constitute an Event of Default, Tenant shall have the right and option to extend the Term
for two (2) additional periods of sixty (60) months each (i.e., the first extension term shall commence on April 1, 2033 and shall expire on March 31, 2038, and the second extension term shall commence on April 1, 2038 and
shall expire on March 31, 2043). Tenant shall exercise its right by giving Landlord prior written 

  
 5 













 
notice, not sooner than fifteen (15) nor later than twelve (12) months in advance of then scheduled expiration of the Term, of Tenant’s election to extend the Term (i.e., not
sooner than December 31, 2031 or later than March 31, 2032 for the first extension term, and not sooner than December 31, 2036 or later than March 31, 2037 for the second extension term). The parties agree that time is of the
essence and that this option is personal to Tenant and is non-transferable to any assignee or sublessee (regardless of whether any such assignment or sublease was made with or without Landlord’s consent)
or other party. 
 (b) Any such extension shall be under the same terms and conditions as provided in the Lease except that: (1) the
Minimum Annual Rent payable by Tenant shall be at the then fair market value (and in no event less than the Minimum Annual Rent payable during the immediately preceding Term) and (2) upon exercise of the second option to extend, there shall be
no further options to extend. 
 (c) For the purposes of this Lease, the term “fair market value” shall mean Landlord’s
reasonable determination of fair market value of rent for office/laboratory/warehouse buildings in the Eagleview Corporate Center. Landlord shall notify Tenant in writing within thirty (30) days after Tenant’s exercise of its option to
extend as to Landlord’s determination of such fair market value rent. Following receipt of Landlord’s determination of fair market value rent, Tenant shall, for a period of fifteen (15) days following such receipt, have the right to
seek an adjustment in Landlord’s determination of fair market value rent. Thereafter, Tenant shall execute a lease renewal agreement in form prescribed by Landlord and reasonably acceptable to Tenant utilizing either Landlord’s
determination or any subsequent mutually agreed upon determination of fair market value within thirty (30) days after Tenant’s receipt of Landlord’s notice; provided, however, if Tenant does not exercise its option to extend by the
date set forth above, or having exercised its option, does not execute a lease renewal agreement within the time period required above, then Tenant shall be deemed to have revoked its option to extend, and the Lease shall terminate, without further
options to extend, at the expiration of the then current Term. 
 (d) The provisions of this Section 7 supersede in their entirety the
provisions of Section 45 of the Current Lease as previously amended by Section 2 of the first Amendment to Lease , which is hereby agreed to be void and of no further force and effect. 

8. Force Majeure. Section 26 of the Lease is hereby amended and restated as follows: 

The time periods for performance of each party’s obligations (including without limitation, construction obligations) under any of the
terms of this Lease shall be extended for periods of time resulting from an event of Force Majeure “Force Majeure” shall mean matters outside of the performing party’s reasonable control including, but not limited to the
following: strikes, lockout, or labor disputes; failure or interruption of or delay in the availability of any one or more public utilities at the Building for the use of performing party or its contractors or
sub-contractors; delays due to governmental regulation or actions or inaction of local, state or federal governments [including, without limitation, any extraordinary delays in issuing building permits,
certificates of occupancy or other similar permits or certificates]; riots, acts of the public enemy, war, invasion, insurrection, mob violence, sabotage or malicious mischief; storm, flood, unusually severe weather or acts of God; fire, explosion,
or casualty; inability to procure, or general shortages of, labor, equipment, facilities, materials or supplies; failure of transportation, epidemics, quarantine restrictions, freight embargoes, or any other cause event or circumstance, whether
similar or dissimilar, beyond the performing party’s control. Force Majeure shall not apply, however, to any monetary obligations hereunder.”

UPON AN EVENT OF DEFAULT, TENANT HEREBY AUTHORIZES AND EMPOWERS ANY PROTHONOTARY OR ATTORNEY OF ANY COURT OF RECORD TO APPEAR FOR TENANT IN
ANY AND ALL ACTIONS FOR RENT IN ARREARS OR TREATED AS IF IN ARREARS AND CHARGES, WHETHER OR NOT PAYABLE AS RENT, AND TO CONFESS JUDGMENT AGAINST TENANT FOR ALL ARREARS OR SUCH SUMS TREATED AS IF IN ARREARS AND THE SAID CHARGES, AND FOR INTEREST AND

CANCELED OR SUSPENDED AND POSSESSION OF THE LEASED SPACE REMAINS IN OR IS RESTORED TO TENANT, LANDLORD SHALL HAVE THE RIGHT UPON ANY SUBSEQUENT EVENT OF DEFAULT OR TERMINATION OF THE LEASE, OR ANY RENEWAL OR EXTENSION HEREOF, TO BRING ONE OR MORE
ACTIONS IN CONFESSION OF JUDGMENT FOR EJECTMENT AS HEREINBEFORE SET FORTH TO RECOVER POSSESSION OF THE LEASED SPACE. IF IN ANY ACTION TO CONFESS JUDGMENT IN EJECTMENT, LANDLORD SHALL CAUSE TO BE FILED IN SUCH ACTION AN AFFIDAVIT SETTING FORTH THE
FACTS NECESSARY TO AUTHORIZE THE ENTRY OF JUDGMENT AND IF A TRUE COPY OF THIS INSTRUMENT (AND THE TRUTH OF THE COPY STATED IN SUCH AFFIDAVIT SHALL BE SUFFICIENT PROOF) BE FILED IN SUCH ACTION, IT SHALL NOT BE NECESSARY TO FILE THE ORIGINAL AS A
