WHEREAS, the Lender has provided funding to the Company in the amount of $80,000.00 under the Original Note;

NOW, THEREFORE, Company has agreed to enter into this Promissory Bridge Note with the Lender and the Lender has agreed to advance, and the Borrower has agreed to incur the Note on the terms and conditions set forth herein, and in connection therewith, for the parties to make the representations and warranties, covenants and undertakings as hereinafter set forth.

For value received, SCANTECH IDENTIFICATION BEAM SYSTEMS LLC, a Delaware limited liability company (the “Company”), hereby promises to pay to the order of AEGUS CORP AND/OR ASSIGNS (the “Lender”) the Principal Amount (as defined below) in the amounts and on the dates set forth herein, together with interest on the unpaid Principal Amount outstanding from time to time from the date each such amount is advanced as provided herein, at a rate of twelve percent (12.0%) per annum, paid at Maturity.

1.Principal Amount. As used herein, the term “Principal Amount” means the aggregate amount of all advances made by the Lender to the Company pursuant to the Original Note prior to the date hereof, plus any additional advances made by the Lender to the Company pursuant to this Note after the date hereof (each, an “Advance”), less all repayments on account of principal from time to time with respect to the Principal Amount, up to the maximum principal amount (exclusive of accrued and unpaid interest) of $500,000.00. This Note is issued in exchange and replacement for, and evidences (i) the same indebtedness incurred prior to the date hereof under that Original Note in the amount of $80,000.00 plus the accrued and unpaid interest incurred on the Original Note as of the date hereof in the amount of $213.33. The indebtedness evidenced by the Original Note is continuing indebtedness, and nothing in the Note shall be deemed to constitute a payment, settlement, or novation of the Original Note, or the release of, or otherwise adversely affect any lien or security interest securing such indebtedness or any rights of Lender against the Company.

​

2.Advances: Each subsequent advance shall be made at the Lender’s discretion in an amount and in increments to be determined by Lender. The Lender shall record, using a form substantially similar to Schedule I attached to this Note, (i) the date and amount of each Advance made by the Lender to the Company, (ii) the date and amount of each payment on account of principal made by the Company to the Lender, and (iii) the resulting outstanding Principal Amount. Entries made in good faith by the Lender shall be binding and conclusive on the parties absent manifest error. For the avoidance of doubt, the Lender shall not have any obligation to make any additional Advance at any time but shall only make Advances at such times and in such amounts as may be agreed by the Lender and the Company.

3.Maturity Date. The Principal Amount and all accrued interest under this Note shall be due and payable upon demand by the Lender on the earlier of either occurrence:

| (a) | November 15, 2024 (the “Maturity Date”).

| (b) | The closing of the contemplated Business Combination between SIBS and MARS.

Notwithstanding the foregoing, the entire unpaid Principal Amount, together with all accrued interest thereon, shall become immediately due and payable upon the occurrence of an Event of Default (as hereinafter defined). There shall be no prepayment penalty if all outstanding indebtedness including any accrued interest is paid to Lender and this Note is paid and satisfied in full prior to the Maturity Date.

4.Interest Rate and Calculation. The Company shall pay interest at a rate of 12.0% per annum on the outstanding Principal Amount computed by multiplying the actual number of days in such period by a daily interest rate based on a 360-day year, which such interest shall be due and payable on the Maturity Date.

5.Additional Equity Consideration.

| (a) | In consideration for the funds received, the Lender will receive newly issued registered shares in STAI as defined in a Shares Issuance Agreement (EXHIBIT A) with STAI. The Lender will receive one share of STAI for every dollar of Principal Amount outstanding to the Company (the “Lender Shares”). For avoidance of doubt, as an example, an outstanding Principal Amount of $500,000.00 would require STAI to issue 500,000 shares to the Lender.

| (b) | In the event the Business Combination does not occur, the Company hereby grants to the Lender or its assignee the right to acquire, at any time at the Lender’s option and upon written notice to the Company, for a purchase price of ten dollars ($10.00), membership interests representing a percentage of the total outstanding equity interests in the Company (determined on a fully diluted basis at the time of such exercise) equal to the percentage determined by dividing (i) the outstanding Principal Amount due under this Note as of the date of such exercise by (ii) $20,010,000.

​

As promptly as practicable after the exercise of the right pursuant to Section 4(a), the STAI shall issue and deliver to the Lender a certificate or certificates and/or instruments, as applicable, for the equity interests to which the Lender is entitled, and the Lender and the STAI shall execute and deliver such joinder or other agreements with respect to equity interests of the STAI as shall be necessary or appropriate to give effect to this Agreement.

6.Registration. STAI shall ensure that the Lendor Shares (i) to the extent feasible and in compliance with all applicable laws and regulations are registered as part of any registration statement issuing shares before or in connection with the Business Combination Closing, or (ii) if no such registration statement is filed in connection with the Business Combination Closing, are promptly registered pursuant to the first registration statement filed by the STAI, which shall be filed no later than 30 days after the Business Combination Closing and declared effective no later than 120 days after the Business Combination Closing.

7.Security. To secure the payment when due of the outstanding Principal Amount and accrued and unpaid interest under this Note, the Company hereby (i) pledges, grants, conveys and assigns to the Lender a security interest in and to all of the Company’s intellectual property rights of any kind (the “Collateral”) and (ii) agrees to, promptly upon request, execute such agreements, UCC- 1 financing statements or other documents or agreements in order to give effect to and perfect such security interest as may be requested from time to time by the Lender (and the Lender is hereby authorized to execute and file any such documents on behalf of the Company).

8.Seniority. This Note shall rank pari passu with the existing Seaport Group SIBS LLC Promissory Note and be senior in priority of payment to all outstanding indebtedness owed by the Company to NACS LLC, AZURE LLC and John Redmond, as set forth in the Subordination Agreement attached to this Note.
