SECOND AMENDMENT TO LEASE 

THIS SECOND AMENDMENT TO LEASE (this “Second Amendment”) is made this
17th day of December, 2018 (the “Effective Date”), by and between 200 SMITH NWALP PROPERTY OWNER LLC, a Delaware limited liability company (the “Landlord”) and
DECIPHERA PHARMACEUTICALS, INC., a Delaware corporation (the “Tenant”). 
 A. WHEREAS, Landlord and Tenant are parties to
that certain Lease dated May 29, 2018, as amended by that First Amendment to Lease dated October 26, 2018 (as amended, the “Lease”) for the lease of certain premises consisting of approximately 44,256 square feet located
at 200 Smith Street, Waltham, Massachusetts, as more particularly described in the Lease (the “Premises”). 
 B. WHEREAS,
Landlord and Tenant wish to amend certain provisions of the Lease as set forth herein. 
 NOW, THEREFORE, in consideration of the
mutual covenants and agreements herein contained and 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: 

AGREEMENT 
 1. Definitions. Capitalized
terms used in this Second Amendment shall have the same meanings ascribed to such capitalized terms in the Lease, unless otherwise provided for herein. 

2. Modifications. Modifications to Lease: 

A. Term Commencement Date. 

(1) The first sentence of Section 4.1 of the Lease is hereby deleted and replaced with the following: 

“The “Term Commencement Date” shall be May 1, 2019 (as such date may be extended to the extent set
forth in Section 5.3 hereof). 
 (2) Section 5.2 of the Lease is hereby deleted. 

B. Estimated Substantial Completion Date. 

(1) The last two sentences of the first paragraph of Section 5.3 of the Lease are hereby deleted and replaced with the
following: 
 “Landlord shall use reasonable efforts to substantially complete the Initial Tenant Work on or before the
date (the “Estimated Substantial Completion Date”) that is the last day of the twenty-second (22nd) week following Landlord’s and Tenant’s mutual approval of the
Construction Documents for all of the Initial Tenant Work. In the event that the Substantial Completion Date is delayed beyond the Estimated Substantial 

  
 1 













 
Completion Date (other than due to a Tenant Delay, as defined in Section 5.11 hereof) and to the extent such delay actually delays Tenant’s commencement of
occupancy of the Premises for the regular conduct of its business, then the Term Commencement Date of this Lease shall be delayed by one day for each day of such delay by Landlord in achieving the Substantial Completion Date. If due to such delay by
Landlord, the Term Commencement Date has not occurred within sixty (60) days of the Estimated Substantial Completion Date (as such date shall be extended for Tenant Delays and Force Majeure), then Tenant shall receive a one day credit against
Basic Rent for each day between the Estimated Substantial Completion Date and the Substantial Completion Date.” 
 (2)
The last sentence of the second paragraph of Section 5.3 of the Lease is hereby deleted and replaced with the following: 

“In the event that substantial completion of the Base Building Work is delayed beyond the Estimated Substantial Completion
Date (other than due to a Tenant Delay in accordance with Section 5.11 hereof) and to the extent such delay actually delays Tenant’s commencement of occupancy of the Premises for the regular conduct of its business,
then the Term Commencement Date shall be deemed to be delayed by one day for each day of such delay by Landlord in the substantial completion of the Base Building Work.” 

(3) The term “Estimated Term Commencement Date” appearing in the second sentence of the third paragraph of
Section 5.7 of the Lease is hereby deleted and the term“Estimated Substantial Completion Date” is inserted in its stead. 

C. Construction Documents. Section 5.4 of the Lease is hereby deleted and replaced with the
following: 
 “Tenant shall cause its architect, SGA, to prepare the plans and specifications for the Initial Tenant
Work (the “Construction Documents”). The Construction Documents shall be submitted to Landlord for its approval, which shall not be unreasonably withheld or delayed. Failure of Landlord to approve or disapprove any
initial submission of the Construction Documents within five (5) Business Days or any resubmission within three (3) Business Days shall constitute approval thereof. For the limited purposes of this paragraph, December 24th and 26th, 2018
shall not be considered Business Days. Any disapproval by Landlord shall be accompanied by a specific statement of the reason(s) therefor.

be defined as follows: 
 “Free Rent” shall mean the Basic Rent and all Taxes and Operating
Expenses that shall be abated (provided Tenant is not in default hereunder) from the Term Commencement Date through the Rent Commencement Date (the “Free Rent Period”). The Basic Rent, Taxes and Operating Expenses due
for any partial calendar month immediately following the Free Rent Period shall be prorated based on the number of days in that month. In no event shall the Free Rent Period be deemed to reduce or eliminate Tenant’s obligation to pay any other
amounts due hereunder other than Basic Rent, Taxes and Operating Expenses. 
 (2) The first sentence of Section 3.1(a)
of the Lease is hereby deleted and replaced with the following: 
 “Tenant agrees to pay the Basic Rent and Additional
Rent to Landlord, or as directed by Landlord, commencing on the Term Commencement Date, without offset, abatement (except as specifically provided in Section 1.1 hereof), deduction or demand.”

an unreserved, non-exclusive basis, of which Tenant shall be entitled to Tenant’s Building Proportionate Share of garage parking spaces to be located in the parking garage serving the Building and the
remaining parking spaces to be located in the open parking area adjacent to the Building.” 
 3. Tenant Delay. Landlord hereby waives any claim
of Tenant Delay which may have resulted from any act or omission on the part of Tenant prior to the Effective Date hereof. 
 4. Real Estate Brokers.
Landlord and Tenant each hereby warrants and represents to the other that it has dealt with no broker in connection with the consummation of this Second Amendment other than Broker (whose commission shall be paid by Landlord), and, in the event of
any brokerage claims predicated upon prior dealings with Landlord or Tenant, the party participating in such prior dealings shall defend the same and indemnify the other party hereto against any such claim. 

5. Governing Law. This Second Amendment shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts (without
regard to conflicts of law).
