Note 7 - Commitments and Contingencies Leases On October 27, 2017, the Company entered into a lease agreement with WCS - 377 Plantation Street, Inc., a Massachusetts nonprofit corporation. Pursuant to the terms of the lease agreement, we agreed to lease 27,043 square feet from the landlord, located at 377 Plantation Street in Worcester, MA (the Facility), through November 2026, subject to additional extensions at the Companys option. Base rent, net of abatements of $0.6 million over the lease term, totals approximately $3.6 million, on a triple-net basis. The terms of the lease also require that we post an initial security deposit of $0.8 million, in the form of a $0.5 million letter of credit and $0.3 million in cash, which increased to $1.3 million ($1.0 million letter of credit, $0.3 million in cash) on November 1, 2019. After the fifth lease year, the letter of credit obligation is subject to reduction. The Facility began operations for the production of personalized CAR T and gene therapies in 2018. The Company leases office space and copiers under agreements classified as operating leases that expire on various dates through 2026. The Companys lease liabilities result from the lease of its Facility in Massachusetts, which expires in 2026, and its copier, which expires in 2021. Such leases do not require any contingent rental payments, impose any financial restrictions, or contain any residual value guarantees. Certain of the Companys leases include renewal options and escalation clauses; renewal options have not been included in the calculation of the lease liabilities and right of use assets as the Company is not reasonably certain to exercise the options. The Company does not act as a lessor or have any leases classified as financing leases. At September 30, 2020, the Company had operating lease liabilities of $2.3 million and right of use assets of $1.1 million, which were included in the Condensed Balance Sheet.
