Exhibit 10.1

PROMISE TO PAY. SINTX Technologies. In c. (“ Borrower” ) promises to pay to First State Community Bank (“ Lender” ), or order, in lawful money of the United States of America, the principal amount of Five Hundred Nine Thousand One Hundred Forty-eight & 00/100 Dollars ($ 509,148.00), together with interest on the unpaid principal balance from March 15, 2021, calculated as described in the “INTEREST CALCULATION METHOD” paragraph using an interest rate of 1.000 % per annum based on a year of 360 days, until paid in full. The interest rate may change under the terms and condition s of the “INTEREST AFTER DEFAULT” section.

PAYMENT. Borrow er will pay this loan in accordance with the following payment schedule:

Borrower understands and agrees that the repayment terms set out in this section are subject to the terms of the Act and Rules and Regulations (as defined in the document titled SBA Protection Program) including, without limitation, those related to payment deferral. As of the date of this Note, Borrower is not required to make any payments on this Note until the earlier of: (1) the date that the SBA remits any forgiveness amount to Lender (or notifies the Lender that no forgiveness is granted), or (2) ten months after the end of the Borrower’s Covered Period, as such term is defined under the Act, Rules and Regulations (the “Deadline”) if the Borrower fails to submit its application for forgiveness by the Deadline. Given the foregoing, Borrower understands and agrees that the payment dates and amounts will be subject to the timing of receipt of forgiveness proceeds and the amount forgiven, and is subject to changes in the Act and Rules and Regulations and, as such, may be modified in the future.

If Borrower submits a loan forgiveness application by the Deadline, Lender will notify Borrower of remittance by SBA of the forgiveness amount (or notify Borrower that SBA determined no loan forgiveness is allowed) when received and if there is a balance remaining, the date the first payment is due and the amount which will be based on the remaining term of the loan with the final payment due 60 months from the Loan Date.

If Borrower does not submit a loan forgiveness application by the Deadline, Borrower will begin making payments based on the remaining term of the loan with the final payment due 60 months from the Loan Date.

Unless otherwise agreed or required by applicable law, payments will be applied first to any escrow or reserve account payments as required under any mortgage, deed of trust, or other security instrument or security agreement securing this Note; then to any accrued unpaid interest; then to principal; and then to any late charges. Borrower will pay Lender at Lender’ s address shown above or at such other place as Lender may designate in writing.

INTEREST CALCULATION METHOD. Interest on this Note is computeded on a 365/360 basis; that is, by applying the ratio of the interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual numb er of days the principal balance is outstanding. All interest payable under this Note is computed using this method. This calculation method results in a higher effective interest rate than the numeric interest rat e stated in this Note.

PREPAYMENT. Borrow er may pay without penalty all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower’ s obligation to continue to make payments under the payment schedule. Rather, early payments will reduce the principal balance due and may result in Borrower’s making fewer payments. Borrower agrees not to send Lender payments marked “paid in full”, “without recourse”, or similar language. If Borrow er sends such a payment, Lender may accept it without losing any of Lender’s rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communication s concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes “payment in full” of the amount ow ed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: First State Community Bank, Columbia Branch, 300 Diego Drive, Columbia, MO 65203.

LATE CHARGE. If a payment is more than 15 days late, Borrower will be charged 5.000 % of the regularly scheduled payment or $50.00, whichever is greater.

INTEREST AFTER DEFAULT. Upon default, including failure to pay upon final maturity, the interest rate on this Note shall be increased by 5.000 percentage points. However, in no event will the interest rate exceed the maximum interest rate limitations under applicable law.
