 Exhibit 10.1 

FOURTH AMENDMENT TO LEASE 

THIS FOURTH AMENDMENT TO LEASE (this “Fourth Amendment”) is made as of September 28, 2018, by and between ARE-MA REGION NO. 38, LLC, a Delaware limited liability company (“Landlord”), and CONSTELLATION PHARMACEUTICALS, INC., a Delaware corporation (“Tenant”). 

RECITALS 
 A.
Landlord and Tenant are parties to that certain Lease Agreement dated as of February 5, 2010, as amended by that certain First Amendment to Lease dated as of October 25, 2011, as further amended by that certain Second Amendment to Lease
dated as of October 18, 2013, as further amended by that certain letter agreement dated as of September 30, 2015, and as further amended by that certain Third Amendment to Lease dated as of September 26, 2016 (as amended, the
“Lease”). Pursuant to the Lease, Tenant leases certain premises containing approximately 36,309 rentable square feet (the “Original Premises”) in a building located at 215 First Street, Cambridge, Massachusetts. The
Original Premises are more particularly described in the Lease. Capitalized terms used herein without definition shall have the meanings defined for such terms in the Lease. 

B. Landlord and Tenant desire, subject to the terms and conditions set forth below, to amend the Lease to, among other things, expand
the size of the Original Premises to include that portion of the fourth floor of the Building consisting of (i) Suite 401-S containing approximately 6,815 rentable square feet (the “Suite 401-S Premises”), and (ii) Suite 430 containing approximately 4,422 rentable square feet (the “Suite 430 Premises”), all as shown on Exhibit A attached to this Fourth Amendment
(collectively, the “Expansion Premises”). 
 NOW, THEREFORE, in consideration of the foregoing Recitals, which are
incorporated herein by this reference, the mutual promises and conditions contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant hereby agree as follows:

  

	1.	 Expansion Premises. In addition to the Original Premises, commencing on the Expansion
Premises Commencement Date (as defined below), Landlord leases to Tenant, and Tenant leases from Landlord, the Expansion Premises. 

  

	2.	 Delivery. Landlord shall use commercially reasonable efforts to deliver the Expansion
Premises to Tenant (“Delivery” or “Deliver”) on or before the Target Expansion Premises Commencement Date. The “Target Expansion Premises Commencement Date” shall be February 1, 2019. If
Landlord fails to timely Deliver the Expansion Premises, Landlord shall not be liable to Tenant for any loss or damage resulting therefrom, and the Lease with respect to the Expansion Premises shall not be void or voidable. Notwithstanding anything
to the contrary contained herein, if Landlord fails to deliver the Expansion Premises to Tenant by March 1, 2019 (as such date may be extended for Force Majeure delays, the “Abatement Date”), then, unless such failure is due to
a delay caused by Tenant, Base Rent payable with respect to the Expansion Premises commencing on the Expansion Premises Rent Commencement Date (as defined below) shall be abated 1 day for each day after the Abatement Date (as such date may be
extended for Force Majeure delays) that Landlord fails to Deliver the Expansion Premises to Tenant. If Landlord does not Deliver the Expansion Premises to Tenant by April 1, 2019, for any reason other than Force Majeure delays, this Fourth
Amendment may be terminated by Tenant by written notice to Landlord, and if so terminated by Tenant, neither Landlord nor Tenant shall have any further rights, duties or obligations under this Fourth Amendment, except with respect to provisions
which expressly survive termination of this Fourth Amendment, and the Lease shall continue in full force and effect as though the parties had never executed this Fourth Amendment. If Tenant does not elect to terminate this Fourth Amendment on or
before April 7, 2019, such right to terminate this Fourth Amendment shall be waived and this Fourth Amendment shall remain in full force and effect. 

  

 

  
 1 

 The “Expansion Premises Commencement Date” shall be the date Landlord
Delivers the Expansion Premises to Tenant. The “Expansion Premises Rent Commencement Date” shall be the date that is 1 month after the Expansion Premises Commencement Date. Upon the written request of Landlord, Tenant shall execute
and deliver a written acknowledgment of the Expansion Premises Commencement Date, the Expansion Premises Rent Commencement Date and the Expansion Premises Expiration Date (as defined below) in substantially the form of the “Acknowledgement of
Commencement Date” attached to the Lease as Exhibit D; provided, however, Tenant’s failure to execute and deliver such acknowledgment shall not affect Landlord’s rights hereunder or under the Lease. 

Except as otherwise expressly set forth in this Fourth Amendment: (i) Tenant shall accept the Expansion Premises in their “as-is” condition as of the Expansion Premises Commencement Date; (ii) Landlord shall have no obligation for any defects in the Expansion Premises; and (iii) Tenant’s taking possession of
the Expansion Premises shall be conclusive evidence that Tenant accepts the Expansion Premises. 
 Except as otherwise expressly set forth in
this Fourth Amendment, Tenant agrees and acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty with respect to the condition of all or any portion of the Expansion Premises, and/or the suitability of
the Expansion Premises for the conduct of Tenant’s business, and Tenant waives any implied warranty that the Expansion Premises are suitable for the Permitted Use. 

Notwithstanding anything to the contrary contained herein, the Suite 401-S Premises and the Suite 430
Premises may be Delivered to Tenant on different dates. If either Suite 401-S or Suite 430 is Delivered to Tenant prior to the other portion of the Expansion Space, then the Lease shall be further amended to
amend, among other things, the Expansion Premises Commencement Date, the Expansion Premises Rent Commencement Date and the defined terms set forth in Section 3 below to reflect the Delivery of the Suite 401-S Premises and the Suite 430 Premises on different dates.

 b. Commencing on the Expansion Premises Rent Commencement Date, Tenant shall commence
paying Base Rent with respect to the Expansion Premises in the amount of $75.50 per rentable square foot of the Expansion Premises per year. Base Rent payable with respect to the Expansion Premises shall be increased on each anniversary of the

and adding the resulting amount to the Base Rent payable with respect to the Expansion Premises immediately before such Expansion Premises Adjustment Date.

desired by and performed by Tenant and reasonably acceptable to Landlord in the Expansion Premises (the “Expansion Premises Improvements”), which Expansion Premises Improvements shall be constructed pursuant to a scope of work
reasonably acceptable to Landlord and Tenant. The Expansion Premises TI Allowance shall be available only for the design and construction of the Expansion Premises Improvements (including Tenant’s project management fees). Tenant acknowledges
that upon the expiration of the Term of the Lease, the Expansion Premises Improvements shall become the property of Landlord and may not be removed by Tenant. Except for the Expansion Premises TI Allowance, Tenant shall be solely responsible for all
of the costs of the Expansion Premises Improvements. The Expansion Premises Improvements shall be treated as Alterations and shall be undertaken pursuant to Section 12 of the Lease. The contractor for the Expansion Premises
Improvements shall be selected by Tenant, subject to Landlord’s approval, which approval shall not be unreasonably withheld, conditioned or delayed. Prior to the commencement of the Expansion Premises Improvements, Tenant shall deliver to

required above. 

 During the course of design and construction of the Expansion Premises Improvements, Landlord shall
reimburse Tenant for the cost of the Expansion Premises Improvements once a month against a draw request in Landlord’s standard form, containing evidence of payment of the applicable costs and such certifications, lien waivers (including a
conditional lien release for each progress payment and unconditional lien releases for the prior month’s progress payments), inspection reports and other matters as Landlord customarily and reasonably obtains, to the extent of Landlord’s
approval thereof for payment, no later than 30 days following receipt of such draw request. Upon completion of the Expansion Premises Improvements (and prior to any final disbursement of the Expansion Premises TI Allowance) Tenant shall deliver to
Landlord the following items: (i) sworn statements setting forth the names of all contractors and subcontractors who did work on the Expansion Premises Improvements and final lien waivers from all such contractors and subcontractors; and (ii)
“as built” plans for the Expansion Premises Improvements. Notwithstanding the foregoing, if the cost of the Expansion Premises Improvements exceeds the Expansion Premises TI Allowance, Tenant shall be required to pay such excess in full
prior to Landlord having any obligation to fund any remaining portion of the Expansion Premises TI Allowance. The Expansion Premises TI Allowance shall only be available for use by Tenant for the construction of the Expansion Premises Improvements
until the date that is 6 months after the Expansion Premises Commencement Date (the “Outside Expansion Premises TI Allowance Date”). Any portion of the Expansion Premises TI Allowance which has not been properly requested by Tenant
from Landlord on or before the Outside Expansion Premises TI Allowance Date shall be forfeited and shall not be available for use by Tenant. 
  

	7.	 Security Deposit. Commencing on the date of this Fourth Amendment, the defined term
“Security Deposit” on Page 1 of the Lease is deleted in its entirely and replaced with the following:

this Fourth Amendment to Landlord, Tenant shall deliver to Landlord an amended Letter of Credit which increases the amount of the existing Letter of Credit being held by Landlord to $424,640.92 or an additional Letter of Credit in the amount of
$182,398.92. 
  

	8.	 Parking. Commencing on the Expansion Premises Commencement Date, subject to the terms of
Section 8 of the Lease, Landlord shall make available to Tenant at then-current market rates (which market rate may be adjusted from time to time) a license for up to an additional 10 parking spaces in the Binney Parking
Garage (“Expansion Premises Parking Spaces”), all of such parking spaces to be on a non-reserved basis. Tenant shall notify Landlord prior to the Expansion Premises Commencement Date as
to how many of the Expansion Premises Parking Spaces Tenant will license pursuant to the Lease. If Tenant elects to license fewer than 10 of such Expansion Premises Parking Spaces as of the Expansion Premises Commencement Date, Tenant shall be
deemed to have waived its right to license any additional Expansion Premises Parking Spaces following the Expansion Premises Commencement Date. As of the Expansion Premises Commencement Date, the market parking rate for the parking spaces is $300.00
per parking space month. The market parking rate shall increase on April 1, 2019, to $325.00 per parking space per month. Tenant’s pro rata share of the Binney Parking Garage shall be adjusted in accordance with the number of Parking
Spaces licensed by Tenant during the Term pursuant to this Section 8. For the avoidance of doubt, commencing on July 1, 2020, the only parking spaces that Tenant will be entitled to use under the Lease shall be the
Expansion Premises Parking Spaces.

	9.	 Brokers. Landlord and Tenant each represents and warrants that it has not dealt with any
broker, agent or other person (collectively, “Broker”) in connection with the transaction reflected in this Fourth Amendment and that no Broker brought about this transaction, other than CBRE. Landlord and Tenant each hereby agrees
to indemnify and hold the other harmless from and against any claims by any Broker claiming a commission or other form of compensation by virtue of having dealt with Tenant or Landlord, as applicable, with regard to this leasing transaction.
Landlord shall pay any commission due to CBRE pursuant to a separate written agreement.

and shall at all times during the Term of the Lease remain in compliance with the regulations of the Office of Foreign Assets Control (“OFAC”) of the U.S. Department of Treasury and any statute, executive order, or regulation
relating thereto (collectively, the “OFAC Rules”), (b) not listed on, and shall not during the term of the Lease be listed on, the Specially Designated Nationals and Blocked Persons List, Foreign Sanctions Evaders List, or the
Sectoral Sanctions Identification List, which are all maintained by OFAC and/or on any other similar list maintained by OFAC or other governmental authority pursuant to any authorizing statute, executive order, or regulation, and (c) not a
person or entity with whom a U.S. person is prohibited from conducting business under the OFAC Rules. 

  

	11.	 Miscellaneous.

method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. Electronic signatures shall be deemed original signatures for purposes of this Fourth Amendment and all
matters related thereto, with such electronic signatures having the same legal effect as original signatures. 
 d. Except as amended
and/or modified by this Fourth Amendment, the Lease is hereby ratified and confirmed and all other terms of the Lease shall remain in full force and effect, unaltered and unchanged by this Fourth Amendment. In the event of any conflict between the

Exhibit 10.1

FOURTH AMENDMENT
TO THE
PRUDENTIAL SUPPLEMENTAL RETIREMENT PLAN

(As amended and restated effective as of January 1, 2009)

(Amending to clarify the definition of “Determination Date” and to address the participation
 of employees on assignment with global business partners)

Purpose and Background

		
	A.
	The Prudential Supplemental Retirement Plan (“Supplemental Plan” or the “Plan”) was amended and restated effective as of January 1, 2009, to comply with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (“Code”).

		
	B.
	Pursuant to Section 8.01(b) of the Supplemental Plan, Executive Vice President of  Corporate Human Resources (or successor thereto) (“EVP”) of The Prudential Insurance Company of America ("Prudential") may adopt minor amendments to the Supplemental Plan without the approval of the Compensation Committee of the Board of Directors of Prudential that are necessary or advisable for purposes of compliance with applicable laws and regulations or relate to administrative practices. 

 
		
	C.
	To ensure the Supplemental Plan’s terms reflect past administrative practice, the EVP deems it advisable to make clarifying changes to the term “Determination Date” which is used for purposes of calculating the Benefits payable to a Participant. 

		
	D.
	The EVP also deems it advisable to amend the Plan to address the participation of employees who are transferred to perform service with a global business partner and are eligible to participate in the Prudential Global Business Partner Non-Qualified Plan.

		
	E.
	The EVP has determined that the foregoing amendments are within the scope of authority granted to the EVP under the terms of the Plan.

Resolution
Effective as of the dates set forth below, the Supplemental Plan is amended as follows: 
		
	1.
	Effective as of January 1, 2018, Section 1.15 “Determination Date” shall be amended in its entirety to read as follows: 

1.15    “Determination Date” means, solely for purposes of calculating the amount of any Benefits under the Plan, the Payment Date set forth in Article V; provided, however, that, the Payment Date for any Participant who is a Home Office Employee shall be determined without regard to any 6-month delay if such Payment Date is based on the date of the Participant’s Separation from Service; and provided, further, that, the Determination Date for any Participant who is a Home Office Employee whose termination of employment with the Company did not constitute a Separation from Service and who either: (a) has Benefits accrued under the Prudential Traditional Retirement Plan or (b) is a Grandfathered Employee and has Benefits accrued under the Prudential Cash Balance Plan that are payable in Annuity Form, shall be the Payment Date that would have applied to the Participant, determined without regard to any applicable 6-month delay, had the Participant’s termination of employment constituted a Separation from Service. 

		
	2.
	Effective as of April 1, 2018, Section 2.04 of the Supplemental Plan is amended and restated in its entirety to read as follows:

2.04    Participants Transferred to Joint Ventures or Global Business Partners.  A Participant who is transferred to perform service for a “Joint Venture” or a “Global Business Partner” as each such term is defined below, shall not be eligible to accrue Supplemental Benefits under Article II of the Plan during the period of the assignment.  In addition, the Participant’s transfer to perform service for the Joint Venture or Global Business Partner, as applicable, shall not constitute a Separation from Service for purposes of triggering a distribution of benefits from the Supplemental Plan. The rules set forth in Section 

413 of the Prudential Traditional Retirement Plan shall be used to determine the accrued Benefits of a Participant attributable to the Prudential Traditional Retirement Plan.  The rules set forth in 2.5 of the Prudential Cash Balance Plan shall be used to determine the accrued Benefits of a Participant attributable to the Prudential Cash Balance Plan.  For purposes of the Supplemental Plan, a “Joint Venture” is a joint venture in which the Company, directly or indirectly, owns at least 20% of the voting power or equity value, but which is not an Affiliate under the terms of the Prudential Merged Retirement Plan.  A “Global Business Partner” is an entity with which Prudential has a business relationship but does not, directly or indirectly, own any voting power or equity value and is not a member of the Company’s Controlled Group.
   
		
	3.
	All capitalized terms not defined herein shall have the meanings ascribed to them in the Supplemental Plan.

		
	4.
	Except where otherwise expressly amended herein, the Supplemental Plan is ratified and confirmed and shall continue in full force and effect.

 

Adopted on behalf of The Prudential Insurance Company of America.
