RECITALS

By Lease dated June 10, 2013 (the "Original Lease"), Landlord did lease to Tenant and Tenant did hire and lease from Landlord certain premises containing 32,217 square feet of rentable floor area on the third (3rd) floor of the building (the "Building") known as and numbered Bay Colony Corporate Center, 1100 Winter Street, Waltham, Massachusetts (referred to herein as the "Original Premises").

By First Amendment to Lease dated as of March 24, 2015 (the "First Amendment"), Landlord and Tenant (i) increased the size of the Original Premises by adding thereto an additional 5,934 square feet of rentable floor area located on the third (3rd) floor of the North Wing of the Building, which space is shown on Exhibit A attached to the First Amendment (the "First Additional Premises" and together with the Original Premises, the "Existing Premises") and (ii) extended the Term of the Original Lease for a period of one (1)  year, upon all of the same terms and conditions contained in the Original Lease except as otherwise provided in the First Amendment to Lease.

Landlord and Tenant presently are negotiating an amendment to the Lease (the "Third Amendment"), which, if and when executed, is anticipated to (i) increase the size of the Existing Premises by adding thereto an additional 21,000 square feet of rentable floor area located on the second (2nd) floor of the Building (the "Second Additional  Premises"), and (ii) extend the Term of the Lease for a period of five (5) year(s) from the date upon which Tenant's Annual Fixed Rent obligations commence with respect to the Second Additional Premises.
