On December 22, 2020, TELA Bio, Inc. (the “Company”) and WPT Land 2 LP (the “Landlord”) entered into a Third Amendment to Lease Agreement (the “Third Amendment”), amending that certain Lease Agreement, dated January 31, 2013 (as subsequently amended, the “Lease Agreement”) relating to the Company’s corporate headquarters and research and development space located at 1 Great Valley Parkway, Malvern, Pennsylvania 19355.

The Third Amendment extends the term of the Lease Agreement from May 31, 2021 to May 31, 2028 with respect to the property originally subject to the Lease Agreement (the “Original Premises”). From June 1, 2021 to May 31, 2022, the Company is obligated to pay the Landlord a monthly base rent of $18,663.07 in respect of the Original Premises, which will increase by $0.35 per rentable square foot on June 1 of each succeeding year during the term.

Pursuant to the Third Amendment, the Company has also leased an additional 8,613 square feet (the “Expansion Premises”) from the Landlord at the Company’s corporate headquarters commencing on the date of delivery of the Expansion Premises by Landlord, which is anticipated to occur no later than March 1, 2023. If the Landlord delivers the Expansion Premises prior to March 1, 2023, the Company will pay the Landlord a monthly base rent in respect of the Expansion Premises based on the rate per rentable square foot as is then applicable to the Original Premises. Beginning on March 1, 2023, the Company will pay a monthly base rent of $10,479.15 in respect of the Expansion Premises, which shall increase annually by $0.35 per rentable square foot beginning on June 1, 2024. The Expansion Premises will expand the Company’s leased square footage in the building from 16,112 square feet to 24,725 square feet (the “Leased Premises”).

The Company has the right, at its option and subject to certain conditions, to extend the term of the Leased Premises for one additional period of five years following the expiration of the term of the Lease Agreement as amended by the Third Amendment, at an annual rate equal to fair market value as described in the Third Amendment.

The foregoing summary of the Third Amendment does not purport to be complete and is qualified in its entirety by reference to the Third Amendment, which will be filed as an exhibit to the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.
