Note 6 — Commitments and Contingencies

Operating Lease Obligations

Beginning in October 2024,
the Company entered into a lease agreement whereby the Company agreed to rent its office and lab facilities under month-to-month tenancy.
The monthly rent payable under the lease is $25 thousand. This month-to-month lease automatically renews every four months, unless
written termination is provided.

Operating costs for short-term
leases include variable lease costs of $0.1 million and less than $0.1 million during the three months ended June 30,
2025 and 2024, compared to $0.2 million and $0.1 million during the six months ended June 30, 2025 and 2024. Starting
from August 2022 the Company recognized lease expense in the amount of monthly rent as incurred. The Company recognized operating
lease costs for monthly rent of $75 thousand and $150 thousand for each of the three and six month periods ending June 30, 2025 and
2024. Total operating lease costs with common area maintenance variable costs were $0.3 million and $0.2 million for the six months
ended June 30, 2025 and 2024.

Contingencies and Indemnifications

From time to time, the Company
may have certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues a liability
for such matters when it is probable that future expenditures will be made and that such expenditures can be reasonably estimated. Significant
judgment is required to determine both probability and the estimated amount.

In the normal course of business,
the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications.
The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the
future, but that have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to
its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations.
