ible Bridge Notes were
deemed to be equity instruments. In addition, the Company allocated the issuance costs incurred to these instruments to the 2024
Convertible Bridge Notes and as such, expensed $107,491
in issuance costs during the year ended December 31, 2024, including $41,579
of original issue discount on the 2024 Convertible Bridge Notes.

The
Company used a Monte Carlo simulation model to calculate the fair value of the 2024 Convertible Bridge Notes and the related
warrants as of the issuance date and for the 2024 Convertible Bridge Notes as of December 31, 2024. These financial instruments were classified within Level 3 of the fair value hierarchy at the initial measurement date, due to the use of unobservable
inputs. The key inputs into the model were as follows at issuance and December 31,
2024:
