On November 22, 2024, Liquidia Technologies, Inc., a Delaware corporation (the “Tenant”) and a wholly owned subsidiary of Liquidia Corporation, a Delaware corporation (the “Company”), entered into an Eighth Amendment (the “Eighth Amendment”) with Durham Keystone Tech 4, LLC, a Delaware limited liability company (the “Landlord”) to that certain Lease Agreement, dated June 29, 2007, by and between GRE Keystone Technology Park One LLC (original predecessor-in-interest to Landlord), as amended by that certain Lease Modification No. 1 dated January 12, 2009, that certain Lease Modification Agreement No. 2 dated December 17, 2010, that certain Third Amendment to Lease Agreement dated June 25, 2014, that certain Fourth Amendment to Lease Agreement dated November 17, 2015, that certain Fifth Amendment to Lease Agreement dated January 23, 2017, that certain Sixth Amendment to Lease Agreement dated June 9, 2017, and that certain Seventh Amendment to Lease Agreement dated November 1, 2018 (collectively, the “Lease”). The Lease covers the Company’s current headquarters, which is approximately 45,095 rentable square feet on the first floor of Keystone Technology Park Building IV, 419 Davis Drive, Durham, North Carolina, 27560 (the “Building”).

The Eighth Amendment provides for a 62-month extension of the Lease, commencing on November 1, 2026 (the “Commencement Date”) and expiring on December 31, 2031 (the “Expiration Date”). Under the terms of the Eighth Amendment, the Tenant has the option to extend the Lease for a period of five additional years by providing written notice to the Landlord not more than 18 months nor less than 12 months prior to the Expiration Date. In addition, upon the expiration (or earlier termination) of the Lease, the Eighth Amendment also provides the Tenant with a one-time “right of first offer” with respect to any vacant portion of the Building, subject to any renewal terms of the Lease.

Beginning on the Commencement Date, the Company’s monthly base rent under the Eighth Amendment will be as follows: (i) $136,224.48 for the first 12 months of the initial term, (ii) $140,320.61 for the second 12 months of the initial term, (iii) $144,529.48 for the third twelve months of the initial term, (iv) $148,851.08 for the fourth 12 months of the initial term, (v) $153,323.00 for the fifth 12 month months of the initial term and (vi) $157,907.66 for the last two months of the initial term. The Tenant will also be responsible for continuing to pay its proportional share of operating expenses.

The Eighth Amendment contains customary representations, warranties and covenants.

The foregoing description of the Eighth Amendment is not complete and is qualified in its entirety by reference to the complete terms and conditions of the Eighth Amendment, which is filed hereto as exhibit 10.1.
