Item 1.01. Entry into a Material Definitive Agreement.

By way of background (a) Shire Human Genetic Therapies, Inc. (“Shire”) (as successor-in-interest to AMAG Pharmaceuticals, Inc.), as tenant, and 92 Hayden Avenue Trust, as landlord, are parties to a lease agreement dated May 22, 2008 (as amended, the “Lease”) covering the entirety of the building (the “Building”) at 100 Hayden Avenue, Lexington, MA (the “Site”), all as more particularly described in the Lease (the “Premises”) and (b) Kiniksa Pharmaceuticals Corp. (“Kiniksa US”), a subsidiary of Kiniksa Pharmaceuticals, Ltd., as subtenant, and Shire, as sublandlord, are parties to a Sublease Agreement dated March 13, 2018 (as amended, the “Sublease”). Further, in connection with the Agreement (as defined below), Kiniksa US entered into a Fourth Amendment (“Fourth Amendment”) to the Sublease with Shire dated as of November 6, 2020 to extend the term of the Sublease by one month to August 31, 2021 (the “Sublease Expiration Date”).

On November 6, 2020, Kiniksa US, as tenant, entered into a Recognition and Attornment Agreement and Amendment of Sublease (the “Agreement”) with 92 Hayden Avenue Trust, as landlord (“Landlord”), pursuant to which Kiniksa US will lease the Premises directly from Landlord upon the Sublease Expiration Date. The Agreement extends the term of the Sublease for the period commencing September 1, 2021 and expiring on August 31, 2023 (the “Extended Term”), unless earlier terminated, upon the same terms and conditions of the Sublease (as amended by the Fourth Amendment), except as specifically amended by the Agreement (as so amended, the “Amended Sublease”), notwithstanding the expiration of the Lease on August 31, 2021.

Upon commencement of the Extended Term (a) Kiniksa US and Landlord will be directly bound by the terms and conditions of the Amended Sublease for the term thereof with the same force and effect as if Landlord were the sublandlord and Kiniksa were the subtenant under the Amended Sublease and (b) Kiniksa US, as tenant, will attorn to Landlord, as landlord, under the Amended Sublease and Landlord, as landlord, will recognize Kiniksa US as its tenant under the Amended Sublease. Further, at such time the Sublease will be amended, to provide for the following, among other things:

The Agreement also provides for standard representations, warranties and indemnification provisions.
