The material differences between the Unsecured Financing and the Secured Financing are summarized below.

Unsecured Status. The Unsecured Notes are unsecured obligations of EigenQ and, following the Business Combination Closing, PubCo. No lien on or security interest in any assets of EigenQ, PubCo or any of their respective subsidiaries secures the Unsecured Notes, and the Unsecured Financing does not include a pledge and security agreement or any other collateral arrangement in favor of the Unsecured Investor. Accordingly, the Unsecured PubCo Notes do not include the events of default included in the Secured PubCo Notes relating to the validity, perfection or priority of any security interest or to any loss of, or damage to, collateral, and the Unsecured Investor will have no lien on, or claim against, any cash collateral securing the Secured Notes, including any cash deposited in the blocked account contemplated by the Secured Financing documents in connection with a release of the non-cash collateral securing the Secured Notes.

Subordination. The Unsecured Notes and all other obligations of EigenQ and, following the Business Combination Closing, PubCo to the Unsecured Investor under the Unsecured Financing documents (including any obligation to pay cash under the Unsecured Warrants) are expressly subordinated in right of payment, enforcement and otherwise to the Secured Notes and all other obligations under the Secured Financing documents, pursuant to a subordination agreement, dated as of October 19, 2026 (the “Subordination Agreement”), by and among the Unsecured Investor, EigenQ, an affiliate of the Secured Investor, as collateral agent for the holders of the Secured Notes (the “Secured Agent”) and SVAQ as an obligor following the Business Combination Closing. Pursuant to the Subordination Agreement, among other things, for so long as any obligations under the Secured Financing remain outstanding:

As a result, for so long as the Secured Notes remain outstanding, EigenQ and PubCo generally will not be permitted to make any payment of principal, premium or redemption amounts on the Unsecured Notes, including at maturity, upon an event of default, upon a change of control, upon the occurrence of the amortization trigger or pursuant to any holder or company optional redemption. The Subordination Agreement does not restrict the conversion of the Unsecured Notes or the exercise of the Unsecured Warrants in accordance with their terms, provided that any cash paid to the Unsecured Investor in connection with any such conversion or exercise remains subject to the Subordination Agreement.

The Subordination Agreement further provides that if the required holder of the Secured Notes grants any amendment, waiver or consent under the Secured Financing documents that makes the terms thereof more favorable or less restrictive to EigenQ or PubCo (for example, by relaxing a financial covenant, extending a cure period, reducing an interest rate, releasing collateral or waiving a default), the corresponding provisions of the Unsecured Financing documents will automatically be amended or waived in the same manner, without any action or consent of the Unsecured Investor. If the holders of the Secured Notes receive a cash fee, a reduction in conversion price, an increase in principal amount, warrants or an increase in interest rate solely as consideration for any such amendment or waiver, the Unsecured Investor will be entitled to receive its pro rata share of such consideration (or the same reduction or increase, in the case of the conversion price or interest rate), with any cash fee added to the principal amount of the Unsecured Notes rather than paid in cash.

Action Limitations. The Unsecured Purchase Agreement and the Unsecured Notes provide that, for so long as any Secured Note remains outstanding, neither the Unsecured Investor nor any other holder of the Unsecured Notes may declare, accelerate or enforce any event of default, require any redemption or payment, commence any action or proceeding to collect or enforce the Unsecured Notes, or take any other affirmative action with respect to the Unsecured Notes, unless the required holder of the Secured Notes has taken a substantially similar action with respect to the Secured Notes, and then only to substantially the same extent and subject in all respects to the Subordination Agreement (the “Action Limitations”). Any action taken in violation of the Action Limitations is null and void.

Unsecured Registration Rights Agreement. The Unsecured Registration Rights Agreement is substantially similar to the Secured Registration Rights Agreement, but provides that any claim for payment under the Unsecured Registration Rights Agreement, including any claim for partial liquidated damages, is subject to the Subordination Agreement solely to the extent such claim constitutes subordinated indebtedness thereunder, and nothing in the Unsecured Registration Rights Agreement amends the Subordination Agreement or authorizes any payment prohibited thereby; and (ii) the Unsecured Registration Rights Agreement will be deemed amended, waived or otherwise modified, without any action or consent of the Unsecured Investor, to the extent provided in the automatic amendment provisions of the Subordination Agreement described above.
