user: Read the legal provision and list the applicable contract clause categories. Provision: Provided there is an Outstanding Balance, on each Installment Date (as defined below), Borrower shall pay to Lender an amount equal to the Installment Amount (as defined below) due on such Installment Date in accordance with Section 8. All payments owing hereunder shall be in lawful money of the United States of America or Conversion Shares (as defined below), as provided for herein, and delivered to Lender at the address furnished to Borrower for that purpose. All payments shall be applied first to (a) costs of collection, if any, then to (b) fees and charges, if any, then to (c) accrued and unpaid interest, and thereafter, to (d) principal. Notwithstanding the foregoing or anything to the contrary herein, so long as Borrower has not received a Lender Conversion Notice (as defined below) or an Installment Notice (as defined below) from Lender where the applicable Conversion Shares have not yet been delivered and so long as no Event of Default has occurred since the Effective Date (whether declared by Lender or undeclared), then Borrower shall have the right, exercisable on not less than five (5) nor more than ten (10) Trading Days (as defined below) prior written notice to Lender to prepay the Outstanding Balance of this Note, in full, in accordance with this Section 1. Any notice of prepayment hereunder (an “ Optional Prepayment Notice ”) shall be delivered to Lender at its registered address or email (provided that for any such Optional Prepayment Notice to be deemed effective if delivered via email, each of the following persons must be copied on such email: John M. Fife ( jfife@chicagoventure.com ), Coby Neuenschwander ( coby@chicagoventure.com ), Chris Stalcup ( cstalcup@chicagoventure.com ), Tina Saxton ( tsaxton@chicagoventure.com ), and Jonathan K. Hansen ( jhansen@hbaalaw.com )) and shall state: (y) that Borrower is exercising its right to prepay this Note, and (z) the date of prepayment, which shall be not less than five (5) nor more than ten (10) Trading Days from the date of the Optional Prepayment Notice. On the date fixed for prepayment (the “ Optional Prepayment Date ”), Borrower shall make payment of the Optional Prepayment Amount (as defined below) to or upon the order of Lender as specified by Lender in writing to Borrower not more than one (1) Trading Day prior to the Optional Prepayment Date. If Borrower exercises its right to prepay this Note, Borrower shall make payment to Lender of an amount in cash (the “ Optional Prepayment Amount ”) equal to 125%, multiplied by the then Outstanding Balance of this Note. If Borrower delivers an Optional Prepayment Notice and fails to pay the Optional Prepayment Amount due to Lender within two (2) Trading Days following the Optional Prepayment Date, Borrower shall forever forfeit its right to prepay this Note pursuant to this Section. Upon issuance of an Optional Prepayment Notice, Lender shall not circumvent the intention of Borrower to make a prepayment pursuant to this Section 1 by attempting to convert the portion of the Outstanding Balance for which Borrower has given notice of its intent to prepay during the period beginning at such time that it receives the Optional Prepayment Notice and ending on the Optional Prepayment Date set forth in the applicable Optional Prepayment Notice.
