In connection with the issuance of the June 2024 Convertible Note, the Company incurred debt issuance costs of $224,221 (including the issuance of 5,333 warrants as a finder’s fee) which is capitalized and will be amortized into interest expense over the term of the June 2024 Convertible Note. Based upon the Company’s analysis of the criteria contained in ASC 815, the Company determined that all the warrants issued to Mast Hill and a third party as a finder’s fee meet the definition of a derivative liability, as the Company cannot avoid a net cash settlement under certain circumstances. Management determined the probability of failing to make an amortization payment when due to be remote and as such the fair value of the 80,000 warrants with an exercise price of $7.50 exercisable until June 5, 2029, which warrant shall be cancelled and extinguished against payment of the June 2024 Convertible Note, has been estimated to be zero. Accordingly, the fair value of the 72,000 warrants with an exercise price of $9.75 exercisable until June 5, 2029 was classified as derivative liability on June 5, 2024. The fair values of the 72,000 warrants with an exercise price of $9.75 exercisable until June 5, 2029 issued on June 5, 2024 were computed using the Black-Scholes option-pricing model with the following assumptions: stock price of $10.39, volatility of 85.72%, risk-free rate of 4.31%, annual dividend yield of 0% and expected life of 5 years. In accordance with ASC 470-20-25-2, proceeds from the sale of a debt instrument with stock purchase warrants are allocated to the two elements based on the relative fair values of the debt instrument without the warrants and of the warrants themselves at time of issuance. The portion of the proceeds allocated to the warrants are accounted for as derivative liability. The remainder of the proceeds are allocated to the debt instrument portion of the transaction. In accordance with ASC 480-10-25-14, the Company determined that the conversion provisions contain an embedded derivative feature and the Company valued the derivative feature separately, recording debt discount and derivative liability in accordance with the provisions of the convertible debt (see Note 7). However, management determined the probability of failing to make an amortization payment when due to be remote and as such the fair value of the embedded conversion feature has been estimated to be zero. The Company recorded a total debt discount of $838,990 related to the original issue discount, common shares issued and warrants issued to Mast Hill, which will be amortized over the term of the June 2024 Convertible Note. On December 15, 2024, the Company and Mast Hill entered into that certain consent, acknowledgement, and waiver agreement, pursuant to which Mast Hill waived all amortization payments required to be made under the June 2024 Convertible Note, the Company paid a waiver fee of $150,000 to Mast Hill, and the Company issued to Mast Hill a common stock purchase warrant for the purchase of up to 150,000 shares of the Company’s common stock (“Pre-Funded Warrants”). The Pre-Funded Warrants are immediately exercisable at issuance and until the Pre-Funded Warrants are exercised in full and have an exercise price of $0.01 per share. The Pre-Funded Warrants were classified as a component of permanent equity on the accompanying consolidated balance sheets as they are freestanding financial instruments that are immediately exercisable, do not embody an obligation for the Company to repurchase its own shares and permit the holder to receive a fixed number of shares of common stock upon exercise. All of the shares underlying the Pre-Funded Warrants have been included in the weighted-average number of shares of common stock used to calculate net loss per share, basic and diluted, attributable to the Company’s common stockholders because the shares may be issued for little or no consideration, are fully vested and are exercisable after the original issuance date of the Pre-Funded Warrants. Based on the Company’s assess, this arrangement was accounted for as a modification of debt and, as such, $838,794 related to the waiver fee and Pre-Fund Warrants issued to Mast Hill were expensed. The convertible note payable as of March 31, 2025 and December 31, 2024 was as follows:
|  | March 31, 2025 |  |  | December 31, 2024 |

In connection with the issuance of the June 2024 Convertible Note, the Company incurred debt issuance costs of $224,221 (including the issuance of 5,333 warrants as a finder’s fee) which is capitalized and will be amortized into interest expense over the term of the June 2024 Convertible Note. Based upon the Company’s analysis of the criteria contained in ASC 815, the Company determined that all the warrants issued to Mast Hill and a third party as a finder’s fee meet the definition of a derivative liability, as the Company cannot avoid a net cash settlement under certain circumstances. Management determined the probability of failing to make an amortization payment when due to be remote and as such the fair value of the 80,000 warrants with an exercise price of $7.50 exercisable until the five-year anniversary of June 5, 2024, which warrant shall be cancelled and extinguished against payment of the June 2024 Convertible Note, has been estimated to be zero. Accordingly, the fair value of the 72,000 warrants with an exercise price of $9.75 exercisable until the five-year anniversary of June 5, 2024 was classified as derivative liability on June 5, 2024. The fair values of the 72,000 warrants with an exercise price of $9.75 exercisable until the five-year anniversary of June 5, 2024 issued on June 5, 2024 were computed using the Black-Scholes option-pricing model with the following assumptions: stock price of $10.39, volatility of 85.72%, risk-free rate of 4.31%, annual dividend yield of 0% and expected life of 5 years. In accordance with ASC 470-20-25-2, proceeds from the sale of a debt instrument with stock purchase warrants are allocated to the two elements based on the relative fair values of the debt instrument without the warrants and of the warrants themselves at time of issuance. The portion of the proceeds allocated to the warrants are accounted for as derivative liability. The remainder of the proceeds are allocated to the debt instrument portion of the transaction. In accordance with ASC 480-10-25-14, the Company determined that the conversion provisions contain an embedded derivative feature and the Company valued the derivative feature separately, recording debt discount and derivative liability in accordance with the provisions of the convertible debt (see Note 11). However, management determined the probability of failing to make an amortization payment when due to be remote and as such the fair value of the embedded conversion feature has been estimated to be zero. The Company recorded a total debt discount of $838,990 related to the original issue discount, common shares issued and warrants issued to Mast Hill, which will be amortized over the term of the June 2024 Convertible Note. On December 15, 2024, the Company and Mast Hill entered into that certain consent, acknowledgement, and waiver agreement (“Agreement”), pursuant to which Mast Hill waived all amortization payments required to be made under the June 2024 Convertible Note, the Company paid a waiver fee of $150,000 to Mast Hill, and the Company issued to Mast Hill a common stock purchase warrant for the purchase of up to 150,000 shares of the Company’s common stock (“Pre-Funded Warrants”). The Pre-Funded Warrants are immediately exercisable at issuance and until the Pre-Funded Warrants are exercised in full and have an exercise price of $0.01 per share. The Pre-Funded Warrants were classified as a component of permanent equity on the accompanying consolidated balance sheets as they are freestanding financial instrument that is immediately exercisable, does not embody an obligation for the Company to repurchase its own shares and permit the holder to receive a fixed number of shares of common stock upon exercise. All of the shares underlying the Pre-Funded Warrants have been included in the weighted-average number of shares of common stock used to calculate net loss per share, basic and diluted, attributable to the Company’s common stockholders because the shares may be issued for little or no consideration, are fully vested and are exercisable after the original issuance date of the Pre-Funded Warrants. Based on the Company’s assess, this arrangement was accounted for as a modification of debt and, as such, $838,794 related to the waiver fee and Pre-Fund Warrants issued to Mast Hill were expensed. The convertible note payable as of December 31, 2024 and 2023 is as follows:
|  | December 31, 2024 |  |  | December 31, 2023 |
