 AGREEMENTS: 

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant hereby agree to amend the Lease as follows: 
 1. Inclusion
of Fourth Amendment Premises. Effective as of the applicable Commencement Date (as defined on Exhibit E attached hereto) set forth on Exhibit E attached hereto, the applicable component of the Fourth Amendment Premises shall be
added to the Premises under the Lease. 
 Landlord anticipates delivering possession of each component of the Fourth Amendment Premises on
or before the applicable Anticipated Delivery Date set forth on Exhibit F attached hereto; provided, however, that if Landlord cannot deliver possession of the applicable component of the Fourth Amendment Premises on or before the applicable
Anticipated Delivery Date due to the failure of the existing tenant of such space to vacate such component of the Fourth Amendment Premises or due to fire or other casualty (provided, that in the event of any such fire or other casualty, the
provisions of Section 18 of the Original Lease shall apply), this Amendment shall not be void or voidable, nor shall Landlord be liable for any loss or damage resulting therefrom. In any event, there shall be no accrual of Yearly Rent, Tax
Share or Operating Expense Share (subject in each instance to the provisions hereof) with respect to each applicable component of the Fourth Amendment Premises until Landlord delivers possession of such component of the Fourth Amendment Premises to
Tenant. Landlord shall use reasonable efforts to deliver possession of each component of the applicable Fourth Amendment Premises as soon as reasonably practicable following the date the existing tenant of such space vacates such component of the
Fourth Amendment Premises, regardless whether such date occurs prior to the Anticipated Delivery Date for such component of the Fourth Amendment Premises and any such earlier date of delivery shall be the Commencement Date with respect to such
component of the Fourth Amendment Premises. In the event that Landlord cannot deliver possession of any component of the Fourth Amendment Premises on or before the applicable Anticipated Delivery Date for such space in the condition required under
Section 2 below due to the failure of the existing tenant of such space to vacate such component of the Fourth Amendment Premises, then Landlord shall use commercially reasonable efforts to cause the existing tenant of such space to vacate such
component of the Fourth Amendment Premises. To the extent not caused by Landlord, Tenant’s inability or failure to take possession of any component of the applicable Fourth Amendment Premises when delivery is tendered by Landlord in the
condition required under Section 2 below shall not delay the Commencement Date with respect to such space or Tenant’s obligation to pay Yearly Rent with respect thereto. 

Notwithstanding the foregoing, if the Commencement Date for any component of the Fourth Amendment Premises does not occur within one hundred
eighty (180) days of the applicable Anticipated Delivery Date for such space (each such 180th day being a “Delivery Deadline”) except if due to fire or other casualty
that is not caused by Landlord’s gross negligence or willful misconduct, Landlord shall provide Tenant with a credit of one (1) day’s Yearly Rent, Tax Share and Operating Expense Share allocable to the applicable component of the
Fourth Amendment Premises for each day beyond the applicable Delivery Deadline for such space until the Commencement Date with respect thereto occurs and if the applicable Commencement Date does not occur within ninety (90) days of the
applicable Delivery Deadline for such component of the Fourth Amendment Premises (each such 90th day being a “Second Delivery Deadline”), such credit shall increase to two
(2) day’s Yearly Rent, Tax Share and Operating Expense Share allocable to such component of the Fourth Amendment Premises for each day beyond the applicable Second Delivery Deadline for such space until the Commencement Date with


  
 2 








 
respect thereto occurs. The foregoing credits shall be applied on a day-for-day basis to Tenant’s rent obligations for the applicable component of the Fourth Amendment Premises beginning on
the Rent Commencement Date (as defined below) applicable to such component of the Fourth Amendment Premises. 
 Accordingly: 

 

	 	(a)	as of the Former Addgene Space Commencement Date (as defined on Exhibit E attached hereto), Article 2 of Exhibit 1, Sheet 1 of the Original Lease shall be amended to add the following after the last paragraph
thereof: 

 “Former Addgene Space: Approximately 7,145 rentable square feet of space on the first (1st) floor of Building 700 of the Complex more particularly shown on Exhibit A to the Fourth Amendment of Lease. 

Equipment Room: Approximately 311 rentable square feet of space on the basement level of Building 700 of the Complex more
particularly shown on Exhibit C to the Fourth Amendment of Lease.” 
 and, 

 

	 	(b)	as of the Former OmniGuide Space Commencement Date (as defined on Exhibit E attached hereto), Article 2 of Exhibit 1, Sheet 1 of the Original Lease shall be amended to add the following after the last paragraph
thereof: 

 “Former OmniGuide Space: Approximately 5,687 rentable square feet of space on the first (1st) floor of Building 700 of the Complex more particularly shown on Exhibit B to the Fourth Amendment of Lease. 

Fourth Amendment Storage Space: Approximately 700 rentable square feet of space on the basement level of Building 700 of the
Complex more particularly shown on Exhibit D to the Fourth Amendment of Lease.” 
 The term of the lease for the Former Addgene
Space and the Equipment Room shall be the period beginning on the Former Addgene Space Commencement Date and ending on June 30, 2019 (June 30, 2019 being the “Expiration Date;” such period being the “Former
Addgene Space Term”), subject to the provisions of Section 9 of this Amendment. 
 The term of the lease for the Former
OmniGuide Space and the Fourth Amendment Storage Space shall be the period beginning on the Former OmniGuide Space Commencement Date and ending on the Expiration Date (the “Former OmniGuide Space Term”), subject to the
provisions of Section 9 of this Amendment. 
 Except as otherwise provided herein or except to the extent inconsistent herewith, all
terms and provisions of the Lease shall be applicable to Tenant’s leasing of the Fourth Amendment Premises. As of the Former Addgene Space Commencement Date, the Premises under the Lease shall include the Former Addgene Space and the Equipment
Room. As of the Former OmniGuide Space Commencement Date, the Premises under the Lease shall include the Former OmniGuide Space and the Fourth Amendment Storage Space.

 2. Condition 
  

	 	(a)	Condition of Premises. The Fourth Amendment Premises shall be leased to Tenant as of, and Landlord shall deliver possession of each component of the Fourth Amendment Premises to Tenant on, the applicable
Commencement Date in the following condition: (a) the same shall be in broom clean condition and free of all tenants and/or occupants and their personal property, (b) the mechanical, electrical and plumbing systems (both the base building
systems and the systems located within the respective spaces) serving the Former Addgene Space and the Former OmniGuide Space, (collectively, the “MEP Systems”), shall be in good working order, (c) decommissioning
reports from the existing tenants of each of the Former Addgene Space and the Former OmniGuide Space shall have been delivered to Tenant in advance of the Former Addgene Space Commencement Date and the Former OmniGuide Space Commencement Date,
respectively, evidencing that each of the Former Addgene Space and the Former OmniGuide Space, as applicable, have been decommissioned in accordance with applicable laws, and (d) Landlord shall deliver the Former OmniGuide Space and the
Equipment Room with the Landlord’s work set forth on Exhibit G hereof completed. The Fourth Amendment Premises shall otherwise be leased to Tenant as of, and Landlord shall deliver possession thereof to Tenant on, the applicable
Commencement Date in its “as is” condition as of the date of this Amendment without any further obligation on the part of Landlord to perform any construction therein or to prepare the same for Tenant’s occupancy or to pay any
allowances therefor, except for the payment of the Fourth Amendment Landlord Contribution as set forth below. 

  

	 	(b)	 MEP Systems. In addition, Tenant shall have the right, prior to the commencement of any Tenant’s Fourth Amendment Work in the Former
Addgene Space and/or the Former OmniGuide Space, to determine whether the MEP Systems serving each such space are, in fact, in good operating order. If Tenant believes that the MEP Systems serving either the Former Addgene Space or the Former
OmniGuide Space are not in good working order, then Tenant may give Landlord written notice (a “Defect Notice”) prior to the time that Tenant commences Tenant’s Fourth Amendment Work in the Former Addgene Space and/or
the Former OmniGuide Space, as applicable. Each Defect Notice shall set forth, with specificity, the manner in which the MEP Systems serving the applicable space are not in good working order. If Tenant fails to provide a Defect Notice with respect
to the MEP Systems in the Former Addgene Space or the Former OmniGuide Space prior to the time that Tenant commences Tenant’s Fourth Amendment Work in the Former Addgene Space or the Former OmniGuide Space, respectively, or if Tenant does not
give Landlord reasonable opportunity (at least three (3) business days) to investigate the claims set forth in a Defect Notice prior to the commencement of Tenant’s Fourth Amendment Work in the Former Addgene Space or the Former OmniGuide
Space, as applicable, then Tenant shall conclusively be deemed to have agreed that the MEP Systems in the Former Addgene Space or the Former OmniGuide Space, respectively, were in good working order as of the applicable Commencement Date. If
Landlord agrees that the MEP Systems in the Former Addgene Space or the Former OmniGuide Space, as applicable, are not in good working order, Landlord shall, at no cost to Tenant, perform any work necessary to place the MEP Systems in the Former
Addgene Space or the Former OmniGuide Space, as applicable, in good working order. Landlord shall have the right, which right shall be exercisable by written notice to Tenant given on or before the date seven (7) days after Landlord receives a
Defect Notice, to object to such Defect Notice. Any dispute under this Section 2(b) may be submitted to arbitration in accordance with the provisions in Article 29.4 of the Original Lease. If it is either agreed




  
 4 









	 	
by the parties, or determined by the arbitrator, that the MEP Systems were not in good working order as of the applicable Commencement Date, then Landlord shall, promptly after such agreement or
determination, perform any work necessary to place the MEP Systems in good working order. The provisions in this Section 2(b) set forth Tenant’s sole rights and remedies in the event of any breach by Landlord of its obligations under this
Section 2(b). Notwithstanding the foregoing, Tenant shall have no right to provide a Defect Notice or object to the condition of the HVAC system serving the Former OmniGuide Space to the extent that the completion of Tenant’s Heat Pump
Installation (as defined on Exhibit G) will remedy the condition of such HVAC system. Nothing herein shall relieve Landlord from its maintenance and repair obligations pursuant to Article 8.5 of the Lease. 


 

	 	(c)	Tenant shall have the right to use the Ph Neutralization system, central vacuum system, RODI water system, potable and non-potable water systems and effluent pumping system (collectively, the “Equipment Room Lab
