SECURED PROMISSORY NOTE

$350,000.00 April 22, 2020

FOR VALUE RECEIVED, the undersigned, T STAMP INC., a Delaware corporation (“Debtor”), hereby promises to pay to SECOND CENTURY VENTURES, LLC, an Illinois limited liability company (“Creditor”), or order, the principal amount of this Note, which is Three Hundred Fifty Thousand Dollars ($350.000.00), payable in the manner and on the terms hereinafter set forth, together with interest accrued from the date of this Note on the unpaid principal balance.

1.       Payment.

1.1 Maturity. The unpaid principal amount hereunder, together with any then unpaid and accrued interest thereon and any other amounts payable hereunder, shall be due and payable on the first to occur of: (i) an Event of Default (as defined below), (ii) a Change in Control (as defined below), or (iii) April 22, 2021 (each, a “Maturity Date”).

1.2 Interest. This Note shall accrue interest, from the date hereof until the principal is repaid as provided in Section 1.1, on any unpaid principal balance at the rate of eight percent (8.0%) per annum, compounded monthly. Interest shall be calculated on the basis of actual number of days elapsed based on a year of 360 days. Accrued but unpaid interest shall be payable on the Maturity Date.

1.3 Maximum Interest Rate. Notwithstanding any provision in this Note, it is the parties’ intent not to contract for, charge or receive interest at a rate that is greater than the maximum rate permissible by law that a court of competent jurisdiction shall deem applicable hereto (which under applicable law shall be deemed to be the laws relating to permissible rates of interest on commercial loans). If any interest payment due hereunder is determined to be in excess of the legal maximum rate, then that portion of each interest payment representing an amount in excess of the then legal maximum rate shall instead be deemed a payment of principal and shall be applied against principal.

1.4 Payments; Allocation of Payments. Principal and interest and all other amounts due hereunder are to be paid in lawful money of the United States of America in federal or other immediately available funds. All payments shall be credited first to interest, fees, costs and expenses then due and the remainder to the principal amount of the Obligations.

2.       Security Interest. Payment and performance of this Note is secured by the Collateral referenced in the Stock Pledge Agreement, dated as of April 22, 2020, by and between the Creditor as pledgee and Tstamp Incentive Holdings, a Wyoming corporation, as pledgor (the “Pledgor”), in a form acceptable to the Creditor (the “Stock Pledge Agreement”).

3.       Default; Demand; Protest.

3.1 The occurrence of an Event of Default shall give rise to the rights and remedies, including the right to accelerate the payment of this Note. The Debtor waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment, notice of any default, diligence in collection and notices of intention to accelerate maturity, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees at any time held by the Creditor on which the Debtor may in any way be liable.
