CONSULTING AGREEMENT

THIS AGREEMENT (the “Agreement”) is made as of October 5, 2026 (the “Effective Date”), by and between T3 Defense Inc., a corporation organized under the laws of United States, with offices at 575 Fifth Ave, 14th Floor, New York, New York (the “Company”), and Shlomo Zakai, CPA, I.D. No. 024385247, operating the accounting practice known as Shlomo Zakai CPA, whose address is at 3 Shaam St' Petach Tiqva (the “Consultant”).

WHEREAS: the Company wishes to engage the Consultant to provide chief financial officer, accounting and bookkeeping services, and the Consultant wishes to provide such services to the Company; and

WHEREAS: the parties intend that Shlomo Zakai personally serve as the Company’s Chief Financial Officer commencing on the Effective Date, while certain accounting and bookkeeping services may be performed by employees or other personnel of the Consultant under his supervision; and

WHEREAS: the Consultant represents that he is qualified and able to perform the Services and the parties desire to regulate their relationship in accordance with the terms and conditions of this Agreement.

NOW, THEREFORE, the parties agree as follows:

1. The Services

**1.1. **The Company hereby engages the Consultant as an independent consultant to provide the services described in Schedule A attached hereto (collectively, the “Services”). The Services consist of (i) chief financial officer services (the “CFO Services”) and (ii) accounting and bookkeeping services (the “Accounting Services”).

**1.2. **Shlomo Zakai shall personally perform the CFO Services and shall serve as the Company’s Chief Financial Officer commencing on the Effective Date. The Company shall take such corporate actions as may be required to effect or confirm such appointment. The parties acknowledge that, in performing duties that by law or applicable regulation are imposed on the Company’s Chief Financial Officer as an officer of the Company, Shlomo Zakai shall act in such officer capacity and nothing in this Agreement shall limit any non-waivable duty applicable to him in that capacity.

**1.3. **The Accounting Services may be performed by the Consultant and/or by employees, accountants, bookkeepers or other personnel engaged by the Consultant under the Consultant’s supervision (the “Consultant Personnel”). The Consultant shall remain responsible for the professional performance of the Accounting Services by Consultant Personnel. Consultant Personnel shall not be deemed officers or employees of the Company solely by reason of performing such services.

**1.4. **If the Company determines that a controller, assistant controller or other similar finance position is required, such person shall be engaged directly by the Company and shall be an employee or service provider of the Company, as applicable. The Company shall be solely responsible for all compensation, benefits, payroll taxes and other costs relating to such person, and such costs shall not be included in the Fees payable to the Consultant under this Agreement.

**1.5. **The Consultant shall cooperate on an ongoing basis with the Company’s management, employees, auditors, legal counsel, consultants and other service providers as reasonably required for the proper performance of the Services. The person within the Company responsible for the engagement shall be the Chief Executive Officer, the Board of Directors, or such other person designated by the Company from time to time.

**1.6. **The Consultant shall devote such time and attention as is reasonably necessary for the proper and timely performance of the Services. The parties acknowledge that this is not an exclusive or full-time engagement, unless otherwise agreed in writing.

**1.7. **The Consultant shall perform the Services faithfully, diligently and professionally, in accordance with applicable law and generally accepted professional standards.

**1.8. **Except for systems, access, information and resources to be provided by the Company as reasonably necessary for the Services, the Consultant shall be responsible for maintaining his own place of work and ordinary equipment and supplies used in providing the Services.

**1.9. **Nothing in this Agreement shall prevent the Consultant from providing services to other clients, including as an accountant, financial consultant or chief financial officer, provided that such activities do not create a material conflict of interest with the Company, involve misuse of the Company’s Confidential Information, or materially interfere with the Consultant’s performance of the Services. The Consultant shall promptly disclose any actual material conflict of interest of which he becomes aware.

2. Term and Termination

**2.1. **This Agreement shall commence on the Effective Date and shall continue for an indefinite term unless terminated in accordance with this Section 2. Either party may terminate this Agreement for any reason by giving the other party thirty (30) days’ prior written notice (the “Notice Period”). During the Notice Period, the Consultant shall continue to provide the Services and the Company shall continue to pay the applicable fees, unless the parties agree otherwise in writing.

**2.2. **The Company’s Board of Directors may remove Shlomo Zakai from his corporate office as Chief Financial Officer at any time to the extent permitted by applicable law and the Company’s governing documents. Unless the Agreement is also terminated in accordance with this Section 2, such removal shall not by itself terminate the Consultant’s right to fees for Services actually performed through the effective date of termination, including the applicable Notice Period where required under Section 2.1.

**2.3. **Either party may terminate this Agreement with immediate effect for Cause. For purposes hereof, “Cause” means:

A. a material breach of this Agreement that is not cured within ten (10) business days after written notice describing the breach in reasonable detail, if such breach is capable of cure;
B. fraud, embezzlement, willful misconduct, or a material breach of fiduciary duty in connection with the Services;
C. a final conviction of, or plea of guilty or nolo contendere to, a felony or an offense involving fraud or dishonesty that materially affects the ability to perform the Services; or
D. a material violation of applicable law in the performance of the Services that has or could reasonably be expected to have a material adverse effect on the Company.

**2.4. **Upon termination, the Consultant shall reasonably cooperate in an orderly transition of the Services, subject to payment of all undisputed amounts due to the Consultant. Accrued payment obligations and Sections 4 through 8, together with Schedule B to the extent applicable by its terms, shall survive termination.

3. Consideration

**3.1. **In consideration of the CFO Services and the Accounting Services, the Company shall pay the Consultant a monthly fee of USD 13,000 plus VAT, if required by applicable law (the “Fee”).

**3.2. **The Fee shall be paid monthly within ten (10) days after receipt by the Company of a duly issued invoice. The Consultant shall be responsible for taxes imposed on the Consultant in respect of the Fees, and the Company may withhold amounts only to the extent required by applicable law.

**3.3. **The Company shall reimburse the Consultant for reasonable out-of-pocket expenses incurred specifically for the Company and approved in advance by the Company, against appropriate supporting documentation. Ordinary overhead of the Consultant is included in the Fees.

**3.4. **In addition to the Fee, the Consultant shall be entitled to receive equity-based compensation, including shares and/or options, in accordance with the Company’s customary compensation practices for its senior officers, subject to approval by the Board of Directors and/or any applicable committee and to the terms of the Company’s applicable equity incentive plan and the relevant award documentation.

2

**3.5. **Except for the Fees, equity-based compensation provided under Section 3.4, approved expense reimbursement, and rights expressly provided under Section 6 relating to indemnification and D&O insurance, the Consultant shall not be entitled to additional compensation unless agreed in writing.

4. Confidentiality and Proprietary Rights

**4.1. **As a condition to this engagement, the Consultant shall comply with the Confidentiality and Proprietary Rights Undertaking attached as Schedule B.

**4.2. **For the avoidance of doubt, this Agreement does not impose a general non-competition restriction on the Consultant. The Consultant remains subject to the confidentiality, conflict-of-interest and limited non-solicitation obligations expressly set forth herein and in Schedule B.

5. Relationship of Parties

**5.1. **Except for Shlomo Zakai’s service as an officer of the Company in his capacity as Chief Financial Officer, the Consultant is and shall remain an independent contractor. Nothing in this Agreement shall create an employer-employee relationship between the Company and the Consultant or any Consultant Personnel, or a partnership, joint venture or agency relationship, except for the authority expressly inherent in or delegated in connection with Shlomo Zakai’s office as Chief Financial Officer.

**5.2. **The Consultant shall be solely responsible for the compensation, payroll obligations, social benefits and taxes of Consultant Personnel and for any other obligations arising from their engagement by the Consultant. Consultant Personnel shall have no claim to employee benefits from the Company solely by reason of providing the Accounting Services.

**5.3. **The Consultant shall have no authority to bind the Company to any contract or commitment except to the extent expressly authorized by the Board of Directors, the Chief Executive Officer, applicable Company policy, or the ordinary authority vested in the Company’s Chief Financial Officer.

6. Officer Indemnification, D&O Insurance and Company Cooperation

**6.1. **During Shlomo Zakai’s service as Chief Financial Officer and thereafter with respect to acts taken during such service, the Company shall provide him with indemnification, advancement of expenses and exculpation to the fullest extent available to other executive officers of the Company under applicable law, the Company’s certificate of incorporation, bylaws and any applicable indemnification arrangements, subject to any non-waivable limitations under applicable law.

**6.2. **The Company shall maintain directors’ and officers’ liability insurance (“D&O Insurance”) covering Shlomo Zakai on terms no less favorable in any material respect than the coverage provided to the Company’s other executive officers, for so long as such insurance is maintained for such officers. Following termination of his service, he shall be entitled to the benefit of any applicable run-off or tail coverage maintained for former executive officers on the same basis as similarly situated former executive officers.

**6.3. **The Company shall provide the Consultant with timely access to the books, records, personnel, systems and information reasonably necessary to perform the Services and to discharge the responsibilities of the Chief Financial Officer. The Consultant shall be entitled to rely in good faith on information supplied by the Company, its subsidiaries, officers, employees and professional advisers unless the Consultant knows, or reasonably should know, that such information is materially inaccurate or incomplete.

**6.4. **The Company shall not require Shlomo Zakai to sign, certify or approve any financial statement, filing, certification or other document unless he has been afforded reasonable access to the information and personnel necessary to review the matter and has had a reasonable opportunity to perform the procedures he considers appropriate in light of his responsibilities.

**6.5. **Except in the case of fraud, willful misconduct or gross negligence by the Consultant, the Consultant shall not be liable for indirect, special, incidental, punitive or consequential damages arising from the Services. Nothing in this Agreement shall limit liability that cannot lawfully be limited, including any non-waivable liability arising from Shlomo Zakai’s service as an officer of the Company.
