The Note bears interest at a per annum rate of 15%, accruing monthly, and matures on October 15, 2024 (the "Maturity Date"); provided, however, that if the Merger Agreement is terminated by the Company pursuant to Section 7.01(d)(ii) of the Merger Agreement, then the Maturity Date shall be 5 business days following the effective date of such termination; provided further, however, that if the Merger Agreement is terminated by McEwen pursuant to Section 7.01(c)(i) or Section 7.01(c)(ii) of the Merger Agreement, then the Maturity Date shall be 20 calendar days following the effective date of such termination. The Note is unsecured and the Company has the right to prepay the Note, in whole or in part, at any time without penalty. The Note will become an intercompany loan between McEwen and the surviving company upon closing.
