6. Possession and Commencement Date. 

(a) Section 4.1 of the Lease is hereby deleted and replaced with the following: 

“4.1. Landlord has delivered to Tenant, broom clean and free of occupants, and Tenant has accepted possession of, the
Premises as of the date hereof. Landlord represents and warrants to Tenant that, as of the date hereof, the heating, ventilation and air-conditioning (“HVAC”), electrical, life safety and plumbing systems of the Building are in good
working condition and, to the best of Landlord’s knowledge, not in violation of Applicable Laws applicable to office and laboratory use, generally. Tenant shall undertake its Tenant Improvements and occupy the Premises for the conduct of its
business in two phases. The “Phase 1 Premises” shall consist of twenty-six thousand seven hundred thirty-four (26,734) square feet of Rentable Area on the sixth (6th) floor of the Building. The “Phase 2
Premises” shall consist of a total of ninety-nine thousand three 

  
 3 








 
hundred thirty-one (99,331) square feet of Rentable Area on the fourth (4th), fifth (5th) and sixth (6th) floors. The Rent Commencement Date shall be determined separately for each
Phase and Base Rent shall be calculated based on the ratio of square footage of the Phase 1 Premises to the entire Premises until such time as the “Rent Commencement Date” occurs with respect to the entire Premises (i.e., until such
time as the Phase 2 Premises Rent Commencement Date occurs). The “Phase 1 Premises Rent Commencement Date” is January 1, 2013. The “Phase 2 Premises Rent Commencement Date” shall be the earlier of (y) the
Date that is the earlier to occur of (i) Substantial Completion of the work described on Exhibit B with respect to the Phase 2 Premises (the “Phase 2 Premises Tenant Improvements” and, together with the Phase 1 Premises
Tenant Improvements, the “Tenant Improvements”), and (ii) November 1, 2013 and (z) the date on which Tenant has occupied any portion of the Phase 2 Premises for the conduct of its business, as opposed to occupying any
portion of the Phase 2 Premises for the installation of the Tenant Improvements. Each of the Phase 1 Premises Rent Commencement Date and the Phase 2 Premises Rent Commencement Date shall be subject to extension for Landlord Delay as further
described in Section 4 of Exhibit B hereto. Each party shall execute and deliver to the other written acknowledgment of the actual Commencement Date, the actual Phase 1 Premises Rent Commencement Date, the actual Phase 2 Premises Rent
Commencement Date and/or the Term Expiration Date within ten (10) business days after request by the other party, substantially in the form attached as Exhibit C hereto. Failure to execute and deliver such acknowledgment, however, shall
not affect the Phase 1 Premises Rent Commencement Date, the Phase 2 Premises Rent Commencement Date, the Term Expiration Date or Landlord’s or Tenant’s liability hereunder. The term “Substantially Complete” or
“Substantial Completion” means that the applicable Phase of Tenant Improvements is substantially complete in accordance with the Approved Plans (as defined in Exhibit B hereto), except for minor punch list items, and that
Tenant is able to lawfully occupy the Premises for the conduct of its business in accordance with the Permitted Use.” 
 (b) The last
sentence of Section 4.2 of the Lease is hereby deleted and replaced with the following: “Tenant shall have until August 31, 2014 (the “TI Deadline”) to requisition the unused portions of the TI
Allowance, after which date Landlord’s obligation to fund such costs shall expire.” 
 7. Rentable Area. Subject to the
revised Rentable Areas agreed to in this Amendment, the parties hereby affirm that Section 6 of the Lease remains in effect, and that the Rentable Areas of the Lease set forth in this Amendment are deemed conclusive between the parties
and are not subject to re-measurement. Landlord and Tenant expressly agree that, in connection with any future additions of space to, or subtractions of space from, the Premises, the measurement standard used in calculating the space so added or
subtracted will be the same standard as that used in arriving at the Rentable Area of Premises, the Building and the Lab Building in Section 5, above. 

  
 4 








 8. Parking. The second sentence of Section 13.5(a) of the Lease is hereby
deleted and replaced with the following: “Tenant has initially designated 27 of the 189 unreserved parking spaces allocable to the Phase 1 Premises as being licenses as of the Phase 1 Premises Rent Commencement Date, with such number increasing
to 42 spaces effective as of August 1, 2013 (and with the remainder of Tenant’s Parking Spaces, i.e. 137 spaces, being treated as allocable to the Phase 2 Premises).” 

9. Work Letter. Landlord and Tenant acknowledge that Tenant has Substantially Completed the Phase I Premises Tenant Improvements. The
final advance of the TI Allowance allocable to the Phase 1 Premises shall not be advanced until completion of the Phase 1 Tenant Improvements in accordance with the Work Letter (including without limitation delivery of those items described in
Section 4 thereof and completion of the punchlist items described on Schedule #1, attached). The portion of the TI Allowance allocable to the Phase 2 Premises (i.e. $ $14,899,650, allocated pursuant to the Lease based on the Rentable Area of
the Phase 2 Premises) shall not be advanced until a Schedule and an Approved TI Budget for the Phase 2 Premises Improvements have been approved by Landlord in accordance with the terms of the Lease. 

10. Broker. Tenant represents and warrants that it has not dealt with any broker or agent in the negotiation for or the obtaining of
this Amendment, other than Richards Barry Joyce & Partners LLC (“Broker”), and agrees to indemnify, defend and hold Landlord harmless from any and all cost or liability for compensation claimed by any such broker or agent,
other than Broker, employed or engaged by it or claiming to have been employed or engaged by it. Broker is not entitled to a leasing commission in connection with the making of this Amendment. 

11. No Default. Tenant represents, warrants and covenants that, to the best of Tenant’s knowledge, Landlord and Tenant are not in
default of any of their respective obligations under the Lease and no event has occurred that, with the passage of time or the giving of notice (or both) would constitute a default by either Landlord or Tenant thereunder. Landlord represents,
warrants and covenants that, to the best of Landlord’s knowledge, Landlord and Tenant are not in default of any of their respective obligations under the Lease and no event has occurred that, with the passage of time or the giving of notice (or
both) would constitute a default by either Landlord or Tenant thereunder. 
 12. Effect of Amendment. Except as modified by this
Amendment, the Lease and all the covenants, agreements, terms, provisions and conditions thereof shall remain in full force and effect and are hereby ratified and affirmed. The covenants, agreements, terms, provisions and conditions contained in
this Amendment shall bind and inure to the benefit of the parties hereto and their respective successors and, except as otherwise provided in the Lease, their respective assigns. In the event of any conflict between the terms contained in this
Amendment and the Lease, the terms herein contained shall supersede and control the obligations and liabilities of the parties. From and after the date hereof, the term “Lease” as used in the Lease shall mean the Lease, as modified by this
Amendment.

 13. Miscellaneous. This Amendment becomes effective only upon execution and delivery
hereof by Landlord and Tenant. The captions of the paragraphs and subparagraphs in this Amendment are inserted and included solely for convenience and shall not be considered or given any effect in construing the provisions hereof. All exhibits
hereto are incorporated herein by reference. Submission of this instrument for examination or signature by Tenant does not constitute a reservation of or option for a lease, and shall not be effective as a lease, lease amendment or otherwise until
execution by and delivery to both Landlord and Tenant. 
 14. Counterparts. This Amendment may be executed in one or more
counterparts, each of which, when taken together, shall constitute one and the same document.
