At any time during the period beginning on August 18, 2022 and ending on August 17, 2024, the entire Principal Balance and all accrued and unpaid interest then outstanding under this Note shall, at the option of the Holder, be convertible (in whole, not in part) into Conversion Shares at the Conversion Price. The Holder shall effect such conversion by providing the Company a conversion notice. Such conversion notice shall specify the entire Principal Balance and accrued but unpaid interest to be converted, the effective Conversion Price, and the effective date of conversion.

Optional Redemption. At any time on or after August 18, 2025, the Company may, at its option and upon 30 days written notice provided to the Holder, elect to redeem the Note (in whole and not in part) and the Holder shall be obligated to surrender the Note, at a redemption price equal to 100% of the outstanding Principal Balance, together with any accrued but unpaid interest thereon to the redemption date. Notwithstanding the preceding or anything in Section 3 to the contrary, after receipt of such redemption notice from the Company, the Holder may, at its option, elect to convert the Principal Balance and accrued interest into Conversion Shares as set forth in Section 3 by giving written notice of such election to the Company no later than 5 days prior to the date fixed for redemption; provided that if the redemption notice is issued after May 31, 2027, the foregoing right of the Holder to elect to convert this Note into Conversion Shares shall not apply.
