The information in Item 2.03 below is incorporated by reference in this Item 1.01.

On April 23, 2020, International Isotopes Inc., through its wholly-owned subsidiary (the “Company”), entered into a Loan Agreement and Promissory Note (collectively the “SBA Loan”) with KeyBank National Association pursuant to the Paycheck Protection Program (the “PPP”) under the recently enacted Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) administered by the U.S. Small Business Administration (the “SBA”). The Company received total proceeds of $495,500 from the SBA Loan. The SBA Loan is scheduled to mature on April 22, 2022 and has a 1.00% interest rate and is subject to the terms and conditions applicable to loans administered by the SBA under the CARES Act. The SBA Loan may be prepaid by the Borrower at any time prior to maturity with no prepayment penalties.

The SBA Loan contains customary events of default relating to, among other things, payment defaults and breaches of representations and warranties. Subject to certain conditions, the SBA Loan may be forgiven in whole or in part by applying for forgiveness pursuant to the CARES Act and the PPP. The amount of loan proceeds eligible for forgiveness is based on a formula based on a number of factors, including the amount of loan proceeds used by the Company during the eight-week period after the loan origination for certain purposes, including payroll costs, interest on certain mortgage obligations, rent payments on certain leases, and certain qualified utility payments, provided that, among other things, at least 75% of the loan amount is used for eligible payroll costs, the employer maintaining or rehiring employees and maintaining salaries at certain level. In accordance with the requirements of the CARES Act and the PPP, the Company intends to use the proceeds from the SBA Loan primarily for payroll costs. No assurance can be given that the Company will be granted forgiveness of the SBA Loan in whole or in part.

The foregoing description of the SBA Loan is qualified in its entirety by reference to the SBA Loan filed as Exhibit 10.1 to this Current Report on Form 8-K, which is incorporated herein by reference.
