Momenta Pharmaceuticals, Inc.
675 West Kendall Street
Cambridge, MA 02142
Attention:    Alejandra Carvajal
Vice President and Deputy General Counsel

Re:
Lease dated as of February 5, 2013 by and between BMR-Rogers Street LLC
(“Landlord”) and Momenta Pharmaceuticals, Inc. (“Tenant”), as amended by First
Amendment to Lease dated as of March 21, 2013, as further amended by Second
Amendment to Lease dated as of May 24, 2013, as further amended by Third
Amendment to Lease dated as of December 30, 2015, and as further amended by
Fourth Amendment to Lease dated as of July 24, 2017 (the “Fourth Amendment”;
collectively, the “Lease”)

Dear Ms. Carvajal:

This letter memorializes certain agreements between Landlord and Tenant with
respect to the application of the Binney TI Allowance. Pursuant to the Fourth
Amendment, Tenant has leased approximately 52,252 square feet on the fourth
(4th) floor of 301 Binney Street, in Cambridge, Massachusetts (the “Binney
Premises”). Pursuant to a Sublease dated September 14, 2016, by and between
Biogen MA Inc. (“Biogen”), as sublessor, and Tenant, as sublessee (the
“Sublease”), Tenant is subleasing the entire fifth (5th) floor of 301 Binney
Street (the “Fifth Floor Premises”).

Pursuant to Section 5.3 of the Fourth Amendment, Landlord shall provide to
Tenant the Binney TI Allowance in the amount of $4,702,680, which shall be used
for certain costs associated with building out the Binney Premises as set forth
therein. Tenant is also concurrently making certain tenant improvements to the
Fifth Floor Premises (the “Sublease Tenant Improvements”), in accordance with
the terms of the Sublease. Tenant is not receiving any tenant allowance funds
from Biogen related to the Fifth Floor Premises.

Tenant has represented to Landlord that the budget for the Binney Tenant
Improvements will be less than the amount of the Binney TI Allowance, and Tenant
has requested that Landlord allow Tenant to allocate the unused portion of the
Binney TI Allowance to Tenant’s build-out costs for the Fifth Floor Premises
instead. As an accommodation, Landlord hereby agrees that, notwithstanding the
provisions of the Lease, Tenant may allocate a portion of the Binney TI
Allowance to the Fifth Floor Premises, subject to the following conditions:

4826-9290-2741.2
 

--------------------------------------------------------------------------------

1.
The Binney TI Allowance may be applied to the costs incurred for tenant
improvements to the Fifth Floor Premises, provided that the same shall be
limited to the same categories of cost and subject to the same restrictions as
set forth in Section 5.2 of the Fourth Amendment.

2.
The Binney TI Allowance shall be disbursed in the manner set forth in the Binney
Work Letter, except that Tenant shall submit separate Fund Requests for costs
related to the Binney Premises and the Fifth Floor Premises, so that such costs
are separately accounted for.

3.
The current budget for the Binney Premises is attached hereto and incorporated
herein as Schedule 1, and the current budget for the Fifth Floor Premises is
attached hereto and incorporated herein as Schedule 2. Such budgets are hereby
approved by Landlord, and shall constitute the “Binney Approved Budget” pursuant
to the Binney Work Letter.

4.
The provisions of the Binney Work Letter shall apply to the Binney Tenant
Improvements and the Sublease Improvements mutatis mutandis.

5.
In the event the Sublease is terminated prior to the completion of the Sublease
Improvements or the Binney TI Deadline, Tenant shall not be entitled to any
subsequent disbursements from the Binney TI Allowance for the Sublease Tenant
Improvements.

Except as modified by this letter, 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. In the event of any conflict between the
terms contained in this letter and the Lease, the terms herein contained shall
supersede and control the obligations and liabilities of the parties.

Capitalized terms used but not defined herein shall have the meanings ascribed
to them in the Lease. This letter shall be governed by the laws of the
Commonwealth of Massachusetts without giving effect to its choice of law
principles. Tenant may not assign its rights or obligations under this letter to
any other person or entity without Landlord’s prior written consent in its sole
discretion, and any purported assignment without Landlord’s prior written
consent shall be null and void. The agreements contained in this letter shall
inure to the benefit of and shall apply to and be binding upon Landlord and
Tenant and their respective successors and permitted assigns. This letter may be
executed in counterparts, each of which shall be an original, and all of which,
taken together, shall constitute one and the same document. A facsimile or
portable document format (PDF) signature on this letter shall be equivalent to,
and have the same force and effect as, an original signature.

Very truly yours,

/s/ KEVIN SIMONSEN
