The Company leased office and laboratory premises in Seattle, Washington pursuant to a lease agreement that commenced in April 2011 and expired on July 31, 2024. This lease was not extended and no other facility lease was entered into as the Company's employees work remotely. The agreement, which required monthly lease payments, was subject to annual rent escalations during the lease term, and contained two five-year options

to extend the lease term. In June 2020, the Company amended the lease agreement to reduce the leased space for the premises from approximately 22,064 square feet to approximately 14,870 square feet, which was accounted for as a lease modification and partial termination of the lease.

Under the lease agreement, the Company was required to pay certain operating costs, in addition to rent, such as common area maintenance, taxes and utilities. Such additional charges are considered variable lease costs and are recognized in the period in which they are incurred. Rent expense was $70,000 for the three months ended September 30, 2024 and variable costs were $47,000. Rent expense was $486,000 for the nine months ended September 30, 2024 and variable costs were $349,000. Rent expense was $208,000 for the three months ended September 30, 2023 and variable costs were $137,000. Rent expense was $658,000 for the nine months ended September 30, 2023 and variable costs were $447,000.

Under the terms of the Agreement, the Company has agreed to pay the Landlord the outstanding monetary obligation of $679,000 (the “Outstanding Debt”) pursuant to that certain Lease Agreement, by and between the Company and the Landlord, dated as of November 19, 2010, as amended through June 30, 2020 (collectively, the “Lease”) as follows: (i) the Landlord’s application of the security deposit in the amount of $70,000, (ii) the Company’s payment to the Landlord of $85,000 (the “First Payment”) no later than five (5) business days after the Agreement Effective Date, and (iii) the Company’s payment to the Landlord of the Outstanding Debt balance of $524,000 (the “Second Payment” and together with the First Payment, the “Payment Milestones”) no later than February 1, 2025. The Agreement stipulates that upon the receipt by the Landlord of the Payment Milestones, the Landlord will fully discharge and forever release the Company from any claim, cause of action, or judgment, legal or equitable, in contract or tort, direct or indirect, presently asserted or not, known or unknown, through the date of the Agreement related to the Company’s monetary obligations under the Lease.

Additionally, under the Agreement, as consideration for the Landlord’s agreement to delay collection of the Outstanding Debt and to not assess additional interest and late fees with respect to the Outstanding Debt, the Company executed a Confession of Judgment (the “Confession”) in favor of the Landlord, and as consideration for the Company’s agreement to execute the Confession, the Landlord agreed not to file any lawsuit or other legal action against the Company related to the Outstanding Debt, or to otherwise cause the Confession to be entered into any legal action or proceeding unless the Company fails to satisfy the Payment Milestones. The Agreement specifies that except as it relates to the matters contemplated in the Agreement, no action by the parties is to be construed as an admission of liability by any party as it relates to such parties’ rights or obligations under the Lease.

In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. Pursuant to such agreements, the Company may indemnify, hold harmless and defend an indemnified party for losses suffered or incurred by the indemnified party. Some of the provisions will limit losses to those arising from third-party actions. In some cases, the indemnification will continue after the termination of the agreement. The maximum potential amount of future payments the Company could be required to make under these provisions is not determinable. The Company has not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. The Company has also entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers to the fullest extent permitted under the Delaware General Corporation Law. The Company currently has directors’ and officers’ insurance.

In

the case of terminating a clinical trial agreement at a particular site, the Company would also be obligated to provide continued support for appropriate medical procedures at that site until completion or termination.
