Exhibit 10.8

​

NON-REDEMPTION AGREEMENT

​

This Non-Redemption Agreement (this “Agreement”) is entered as of [•], 2024 by and among Mars Acquisition Corp. (“Mars”), Mars Capital Holding Corporation, a British Virgin Islands business company with limited liability (the “Sponsor”), and ScanTech AI Systems Inc., a Delaware corporation and wholly owned subsidiary of Mars (“Pubco”) and the undersigned investors (collectively, the “Investor”).

​

RECITALS

​

WHEREAS, the Sponsor currently holds Mars ordinary shares, par value $0.000125 per share, initially purchased in a private placement prior to Mars’ initial public offering (the “Founder Shares”);

​

WHEREAS, Mars expects to hold an extraordinary general meeting of shareholders (the “Meeting”) for the purpose of approving, among other things, an amendment to Mars’s Amended and Restated Memorandum and Articles of Association (the “Mars Memorandum and Articles”) to extend the date by which Mars must consummate an initial business combination by nine additional months until November 16, 2024 (the “Extension”);

​

WHEREAS, Mars Memorandum and Articles provides that a shareholder of Mars may redeem its ordinary shares, par value $0.000125 per share, initially sold as part of the units in Mars’s initial public offering (whether they were purchased in Mars’s initial public offering or thereafter in the open market) (the “Public Shares” and together with the Founder Shares, the “Ordinary Shares”) in connection with the any amendment to the Mars Memorandum and Articles, on the terms set forth in the Mars Memorandum and Articles (“Redemption Rights”);

​

WHEREAS, during the period of the Extension the Sponsor intends to cause Mars to consummate the business combination (the “Business Combination”), with the ScanTech Identification Beam Systems, LLC, a Delaware limited liability company (“ScanTech”) and other parties thereto pursuant to the business combination agreement (as it may be further amended or supplemented from time to time) entered on September 5, 2023. Upon closing of the Business Combination, Pubco will become the surviving operating company and apply for listing of its shares (“Pubco Common Stock”) on Nasdaq under the proposed symbol “STAI.” No securities of Mars will be traded following the consummation of the Business Combination;

​

Whereas, subject to the terms and conditions of this Agreement, Investor is willing to forego the exercise of its Redemption Rights in connection with the Extension, or to validly rescind any previously submitted redemption demand, of certain of the Public Shares held by such Investor upon the terms set forth herein, and Pubco desires to issue, and Mars and Sponsor desire to cause Pubco to issue, that number of Pubco Common Stock set forth opposite such Investor’s name on Exhibit A (the “Promised Securities”), in connection with Mars’ completion of the Business Combination.

​

NOW THEREFORE, in consideration of the mutual covenants and agreements set forth herein and for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Investor, Mars, Pubco and the Sponsor hereby agree as follows:

​

1. | Terms of Issuance

​

| 1.1 | Upon the terms and subject to the conditions of this Agreement, if (a) as of 5:30 PM Eastern on the date of the Meeting, Investor holds the Investor Shares (as defined below), (b) Investor does not exercise (or exercised and validly rescinds) its Redemption Rights with respect to such Investor Shares in connection with the Meeting, and (c) the Extension is approved at the Meeting,, then Pubco will issue, and Mars and Sponsor will cause Pubco to issue, to Investor for no additional consideration the Promised Securities set forth on Exhibit A. “Investor Shares” shall mean an amount of the Public Shares presently held by Investor equal to the lesser of an aggregate amount of (i) [•] Public Shares, and (ii) 9.9% of the Public Shares that are not to be redeemed, including those Public Shares subject to non-redemption agreements with other Mars shareholders similar to this Agreement on or about the date of the Meeting. The Sponsor and Mars agree to provide Investor with the final number of Investor Shares subject to this Agreement no later than 9:30 AM Eastern on the first business day before the date of the Meeting (and in all cases a sufficient amount of time to allow the Investor to exercise Redemption Rights with regard to any Investor Shares in excess of 9.9% of the Public Shares), provided, that such amount shall not exceed [•] Public Shares.

​

​

| 1.2. | Mars, the Sponsor and Investor hereby agree that the issue by Pubco of the Promised Securities to Investor shall be subject to the conditions that (i) the Business Combination is consummated; and (ii) Investor executes the Joinder (as defined in Section 1.8).

​

Upon the satisfaction of the foregoing conditions, as applicable, Pubco shall promptly issue, and Mars and Sponsor shall cause Pubco to promptly issue, (and no later than two (2) business days following the closing of the Business Combination) the Promised Securities to Investor (or its Permitted Transferees) free and clear of any liens or other encumbrances, other than restrictions on transfer imposed by the securities laws. The Sponsor and Mars covenant and agree to cause Pubco to facilitate such transfer to Investor (or its Permitted Transferees) in accordance with the foregoing.

​

| 1.3. | Adjustment to Share Amounts. If at any time the number of outstanding Ordinary Shares are increased or decreased by a consolidation, combination, subdivision or reclassification of the Ordinary Shares of Mars or other similar event, then, as of the effective date of such consolidation, combination, subdivision, reclassification or similar event, all share numbers referenced in this Agreement shall be adjusted in proportion to such increase or decrease in the Ordinary Shares of Mars. For the avoidance of doubt, the issuance of Pubco Common Stock to the existing shareholders of ScanTech in connection with the Business Combination shall not cause any such adjustment.

​

| 1.4. | Merger or Reorganization, etc. If there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving Mars in which its Ordinary Shares are converted into or exchanged for securities, cash or other property, then, following any such reorganization, recapitalization, reclassification, consolidation or merger, in lieu of ordinary shares of Mars, the Sponsor shall transfer, with respect to each Pubco Common Stock to be issued hereunder, the kind and amount of securities, cash or other property into which such Promised Securities converted or exchanged.

​

| 1.5. | Forfeitures, Transfers, etc. Investor shall not be subject to forfeiture, surrender, claw-back, transfers, disposals, exchanges, lock-up or earn-outs for any reason on the Promised Securities.

​

| 1.6. | Delivery of Shares; Other Documents. At the time of the issue of Promised Securities hereunder, Pubco shall deliver, and Mars and Sponsor shall cause Pubco to deliver, the Promised Securities to Investor in book-entry form effected through Pubco’s register of members (or other equivalent register) and through Mars’s transfer agent. The parties to this Agreement agree to execute, acknowledge and deliver such further instruments and to do all such other acts, as may be necessary or appropriate to carry out the purposes and intent of this Agreement.

​

| 1.7. | Registration Rights. In connection with the issuance of the Promised Securities, Investor shall be entitled to registration rights set forth in that certain Registration Rights Agreement, dated February 13, 2023, by and among Mars, Mars’s officers, directors and insiders and the Sponsor (as it exists on the date of the Agreement, the “Registration Rights Agreement”), and Pubco and Investor shall execute the Joinder (as defined below).

​

| 1.8. | Joinder to Agreement. In connection with the issue of the Promised Securities to Investor, Investor shall execute a joinder to the Registration Rights Agreement in substantially the form attached here to as Exhibit B (the “Joinder”) pursuant to which Investor shall agree with Pubco to be bound by the terms and provisions of the Registration Rights Agreement as a “holder” thereunder with respect to the Promised Securities (upon acquisition thereof) as “Registrable Securities” thereunder.

​

| 1.9 | Termination. This Agreement and each of the obligations of the undersigned shall terminate on earlier of (a) the failure of Mars’s shareholders to approve the Extension at the Meeting, (b) Mars’s abandonment of the Extension prior to the implementation thereof, (c) the fulfillment of all obligations of parties hereto, (d) the liquidation or dissolution of Mars prior to completing a Business Combination, (e) the mutual written agreement of the parties hereto; or (f) if Investor exercises its Redemption Rights with respect to any Investor Shares in connection with the Meeting and such Investors Shares are actually redeemed in connection with the Meeting. Notwithstanding any provision in this Agreement to the contrary Pubco’s obligation to issue, and Mars’ and Sponsor’s obligation to cause Pubco to issue, the Promised Securities to Investor shall be conditioned on (i) the satisfaction of the conditions set forth in Section 1.2 and (ii) such Investor Shares not being redeemed in connection with the Meeting

​

​

2. | Representations and Warranties of Investor. Investor represents and warrants to, and agrees with, the Sponsor that:

​

| 2.1. | No Government Recommendation or Approval. Investor understands that no federal or state agency has passed upon or made any recommendation or endorsement of the offering of the Promised Securities.

​

| 2.2. | Accredited Investor. Investor is an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended, (the “Securities Act”) or a “qualified institutional buyer” as defined in Rule 144A under the Securities Act, and acknowledges that the sale contemplated hereby is being made in reliance, among other things, on a private placement exemption to “accredited investors” under the Securities Act and similar exemptions under state law.

​

| 2.3. | Intent. Investor is acquiring the Promised Securities solely for investment purposes, for such Investor’s own account (and/or for the account or benefit of its members or affiliates, as permitted), and not with a view to the distribution thereof in violation of the Securities Act and Investor has no present arrangement to sell Promised Securities to or through any person or entity except as may be permitted hereunder.

​

| 2.4. | Restrictions on Transfer; Trust Account; Redemption Rights.

​

| 2.4.1. | [Reserved.]

​

| 2.4.2. | Investor acknowledges and agrees that the Promised Securities are not entitled to, and have no right, interest or claim of any kind in or to, any monies held in the trust account into which the proceeds of Mars’s initial public offering were deposited (the “Trust Account”) or distributed as a result of any liquidation of the Trust Account.

​

| 2.4.3. | Investor agrees, solely for the benefit of and, notwithstanding anything else herein, enforceable only by Mars, to waive any right that it may have to elect to have Mars redeem any Investor Shares in connection with the Extension and agrees not to redeem or otherwise exercise any right to redeem, the Investor Shares in connection with the Extension and to reverse and revoke any prior redemption elections made with respect to the Investor Shares in connection with the Extension. For the avoidance of doubt, nothing in this Agreement is intended to restrict or prohibit Investor’s ability to redeem any Public Shares other than the Investor Shares, or to trade or redeem any Public Shares (other than the Investor Shares) in its discretion and at any time or trade or redeem any Investor Shares in its discretion and at any time after the date of the Meeting.

​

| 2.4.4. | Investor acknowledges and understands the Promised Securities will be offered by Pubco in a transaction not involving a public offering in the United States within the meaning of the Securities Act and have not been registered under the Securities Act and, if in the future Investor decides to offer, resell, pledge or otherwise transfer Promised Securities, such Promised Securities may be offered, resold, pledged or otherwise transferred only (A) pursuant to an effective registration statement filed under the Securities Act, (B) pursuant to an exemption from registration under Rule 144 promulgated under the Securities Act, if available, or (C) pursuant to any other available exemption from the registration requirements of the Securities Act, and in each case in accordance with any applicable securities laws of any state or any other jurisdiction. Investor agrees that, if any transfer of the Promised Securities or any interest therein is proposed to be made, as a condition precedent to any such transfer, Investor may be required to deliver to Pubco an opinion of counsel satisfactory to Pubco that registration is not required with respect to the Promised Securities to be transferred. Absent registration or another available exemption from registration, Investor agrees it will not transfer the Promised Securities.

Investor’s subscription and payment for and continued beneficial ownership of the Promised Securities will not violate any applicable securities or other laws of Investor’s jurisdiction.

​

| 2.10. | Authority. This Agreement has been validly authorized, executed and delivered by Investor and is a valid and binding agreement enforceable in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance, moratorium, reorganization, or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by equitable principles of general application and except as enforcement of rights to indemnity and contribution may be limited by federal and state securities laws or principles of public policy.

​

| 2.11. | No Conflicts. The execution, delivery and performance of this Agreement and the consummation by Investor of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) Investor’s organizational documents, (ii) any agreement or instrument to which Investor is a party or (iii) any law, statute, rule or regulation to which Investor is subject, or any order, judgment or decree to which Investor is subject, in the case of clauses (ii) and (iii), that would reasonably be expected to prevent Investor from fulfilling its obligations under this Agreement.

​

| 2.12. | No Advice from Sponsor. Investor has had the opportunity to review this Agreement and the transactions contemplated by this Agreement with Investor’s own legal counsel and investment and tax advisors. Except for any statements or representations of the Sponsor explicitly made in this Agreement, Investor is relying solely on such counsel and advisors and not on any statements or representations, express or implied, of the Sponsor or any of its representatives or agents for any reason whatsoever, including without limitation for legal, tax or investment advice, with respect to this investment, the Sponsor, Mars, the Promised Securities, the transactions contemplated by this Agreement or the securities laws of any jurisdiction.

​

The parties to this Agreement shall cooperate with one another to assure that such disclosure is accurate. Mars agrees that the name of the investor shall not be included in any public disclosures related to this Agreement unless required by applicable law, regulation or stock exchange rule. Investor (i) acknowledges that the Sponsor may possess or have access to material non-public information which has not been communicated to the Investor; (ii) hereby waives any and all claims, whether at law, in equity or otherwise, that he, she, or it may now have or may hereafter acquire, whether presently known or unknown, against the Sponsor or any of Mars’s officers, directors, employees, agents, affiliates, subsidiaries, successors or assigns relating to any failure to disclose any non-public information in connection with the transaction contemplated by this Agreement, including any potential business combination involving Mars, including without limitation, any claims arising under Rule 10-b(5) of the Exchange Act; and (iii) is aware that the Sponsor is relying on the truth of the representations set forth in Section 3 of this Agreement and the foregoing acknowledgement and waiver in this Section 12, in connection with the transactions contemplated by this Agreement.

​

14. | Independent Nature of Rights and Obligations. Nothing contained herein, and no action taken by any party pursuant hereto, shall be deemed to constitute Investor and the Sponsor as, and the Sponsor acknowledges that Investor and the Sponsor do not so constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Investor and the Sponsor are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement or any matters, and the Sponsor acknowledges that Investor and the Sponsor are not acting in concert or as a group, and the Sponsor shall not assert any such claim, with respect to such obligations or the transactions contemplated by this Agreement.

​

​

15. | Most Favored Nation. In the event the Sponsor or Mars enter one or more other non-redemption agreements before or after the execution of this Agreement in connection with the Meeting, the Sponsor and Mars represent that the terms of such other agreements are not materially more favorable to such other investors thereunder than the terms of this Agreement are in respect of the Investor. In the event that another investor is afforded any such more favorable terms than the Investor, the Sponsor shall promptly inform the Investor of such more favorable terms in writing, and the Investors shall have the right to elect to have such more favorable terms included herein, in which case the parties hereto shall promptly amend this Agreement to effect the same.
