Re: Initial Public Offering
Ladies and Gentlemen:
This letter (this “Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and between X3 Acquisition Corp. Ltd., a Cayman Islands exempted company (the “Company”) and ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ & Company, Incorporated, as representative (the “Representative”) of the underwriters (the “Underwriters”), relating to an underwritten initial public offering (the “Public Offering”), of up to 23,000,000 of the Company’s units (including up to 3,000,000 units which may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one Class A ordinary share, par value $0.0001 per share, of the Company (the “Class A Ordinary Shares”) and one-half of one redeemable warrant (each whole warrant, a “Warrant”). Each Warrant entitles the holder thereof to purchase one Class A Ordinary Share at a price of $11.50 per share, subject to adjustment. The Units shall be sold in the Public Offering pursuant to the registration statement on Form S-1 (File No. 333-290299) and prospectus (the “Prospectus”) filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”) and the Company shall apply to have the Units listed on the Nasdaq Global Market. Certain capitalized terms used herein are defined in paragraph 11 hereof.
In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, X3 Acquisition Management LLC, a Delaware limited liability company (the “Sponsor”) and each of the undersigned individuals, each of whom is, or will be, a member of the Company’s board of directors and/or management team (each an “Insider” and, collectively, the “Insiders”), hereby agree with the Company as follows:
1. The Sponsor and each Insider agree that if the Company seeks shareholder approval of a proposed Business Combination, then in connection with such proposed Business Combination, it, he or she shall (i) vote all Founder Shares and any shares acquired by it, him or her in the Public Offering or the secondary public market in favor of such proposed Business Combination, except that it, he or she shall not vote any Class A Ordinary Shares that it, he or she purchased after the Company publicly announces its intention to engage in such proposed Business Combination for or against such proposed Business Combination and (ii) not redeem any Class A Ordinary Shares owned by it, him or her in connection with such shareholder approval. If the Company seeks to consummate a proposed Business Combination by engaging in a tender offer, the Sponsor and each Insider agrees that it, he or she will not sell or tender any Ordinary Shares owned by it, him or her in connection herewith.
2. The Sponsor and each Insider agree that in the event that the Company fails to consummate a Business Combination by the date that is 24 months after the closing of the Public Offering, or such earlier date as Company’s board of directors may approve, or such later date as the Company’s shareholders may approve, in each case in accordance with the Company’s amended and restated memorandum and articles of association, as may be amended from time to time (the “Completion Window” and the “Memorandum and Articles,” respectively), the Sponsor and each Insider shall take all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten (10) business days thereafter, subject to lawfully available funds therefor, redeem 100% of the Class A Ordinary Shares sold as part of the Units in the Public Offering (the “Offering Shares”), at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (which interest shall be net of taxes payable and less up to $100,000 of interest income to pay dissolution expenses), divided by the number of Offering Shares then in issue, which redemption will completely extinguish the Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law. The Sponsor and the Insiders agree to not propose any amendment to the Memorandum and Articles not for the purposes of approving, or in conjunction with the consummation of, a Business Combination (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with a Business Combination or to redeem one hundred per cent (100%) of the Offering Shares if the Company has not consummated a Business Combination within the Completion Window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity, unless the Company provides its Public Shareholders with the opportunity to redeem their Offering Shares upon effectiveness of any such amendment at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the Trust Account and not previously released to the Company to pay its taxes, divided by the number of Offering Shares then in issue, subject to applicable law. The Sponsor and each Insider acknowledges that it, he or she will not be entitled to rights to liquidating distributions from the Trust Account with respect to any Founder Shares held by it, him or her if the Company fails to complete a Business Combination within the Completion Window; although it, he or she will be entitled to liquidating distributions from the Trust Account with respect to any Offering Shares it, he or she holds if the Company fails to complete a Business Combination within the prescribed time frame. The Sponsor and each Insider hereby further acknowledge that it, he or she will not be entitled to (a) redemption rights with respect to any Founder Shares and Offering Shares held by it, him or her, in connection with the consummation of a Business Combination, or (b) redemption rights with respect to Founder Shares and Offering Shares held by it, him or her in connection with a shareholder vote to amend the Memorandum and Articles in the manner described above.
3. To the fullest extent permitted by applicable law and the Memorandum and Articles, the Company hereby agrees to defend, indemnify, hold harmless and exonerate (including the advancement of expenses to the fullest extent permitted by applicable law) the Sponsor and its members (present and former), managers and affiliates and their respective present and former officers and directors (each, a “Sponsor Indemnitee”) from any and all costs, fees, expenses, judgments, liabilities, fines, penalties, reasonable attorneys’ fees and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such costs, fees, expenses, judgments, liabilities, fines, penalties and amounts paid in settlement) actually, and reasonably, incurred by a Sponsor Indemnitee or on a Sponsor Indemnitee’s behalf in connection with any threatened, pending or completed action, suit, arbitration, mediation, alternate dispute resolution mechanism, investigation, inquiry, hearing or any other actual, threatened or completed proceeding instituted by the Company or any third party, whether civil, criminal, administrative or investigative in nature, in respect of any investment opportunities sourced by a Sponsor Indemnitee for the Company or any liability arising with respect to a Sponsor Indemnitee’s activities in connection with the affairs of the Company (in each case to the extent that such indemnification, hold harmless and exoneration obligations with respect to such matters are not expressly covered by a separate written agreement between the Company and the applicable Sponsor Indemnitee); provided, that in no event shall a Sponsor Indemnitee be entitled to be indemnified or held harmless hereunder in respect of any costs, fees, expenses, judgments, liabilities, fines, penalties and amounts paid in settlement (if any) that a Sponsor Indemnitee may incur by reason of such person’s own actual fraud or intentional misconduct; provided, further, that, for the avoidance of doubt, under no circumstance shall a Sponsor Indemnitee have a claim to any monies or assets held in the Trust Account, and the Company shall not be permitted to procure monies or assets held in the Trust Account for the satisfaction of its obligations to any Sponsor Indemnitee in respect of the indemnification provided hereunder. The Sponsor Indemnitees shall be third party beneficiaries of this paragraph.
4. During the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the undersigned shall not, without the prior written consent of the Representative, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder, any units, Class A Ordinary Shares, the Company’s Class B ordinary shares, par value $0.0001 per share (the “Class B Ordinary Shares” and, together with the Class A Ordinary Shares, the “Ordinary Shares”), warrants or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares; provided, however, that the foregoing shall not apply to transfers to the Sponsor by the Insiders or (ii) publicly announce any intention to effect any transaction specified in clause (i); provided, however, the Company may (1) issue and sell the Private Placement Warrants; (2) issue and sell the additional Units to cover the underwriters’ over-allotment option (if any); (3) register with the Commission pursuant to an agreement to be entered into concurrently with the issuance and sale of the securities in the Public Offering, the resale of the Private Placement Warrants and the Founder Shares; and (4) issue securities in connection with the Business Combination. If the undersigned is an officer or director of the Company, the undersigned further agrees that the forgoing restrictions shall be equally applicable to any issuer-directed Units that the undersigned may purchase in the Public Offering.

5. In the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any officer, member or manager of the Sponsor) agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) to which the Company may become subject as a result of any claim by (i) any third party (other than the Company’s independent public accountants) for services rendered or products sold to the Company or (ii) a prospective target business with which the Company has entered into a letter of intent, confidentiality or other similar agreement or business combination agreement (a “Target”); provided, however, that such indemnification of the Company by the Sponsor shall apply only to the extent necessary to ensure that such claims by a third party for services rendered (other than the Company’s independent public accountants) or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (A) $10.00 per share of the Offering Shares or (B) such lesser amount per share of the Offering Shares held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case including interest earned on the funds held in the Trust Account and net of taxes payable, except as to any claims by a third party or Target that executed an agreement waiving claims against and all rights to seek access to the Trust Account whether or not such agreement is enforceable. In the event that any such executed waiver is deemed to be unenforceable against such third party, the Sponsor shall not be responsible for any liability as a result of any such third-party claims. Notwithstanding any of the foregoing, such indemnification of the Company by the Sponsor shall not apply as to any claims under the Company’s obligation to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Sponsor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within fifteen (15) days following written receipt of notice of the claim to the Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense.
6. To the extent that the Underwriters do not exercise their over-allotment option to purchase an additional 3,000,000 Units (as described in the Prospectus), the Sponsor agrees, upon the expiration or waiver of such option, to forfeit and surrender for no consideration for cancellation, a number of Founder Shares equal to the product of 750,000 multiplied by a fraction, (i) the numerator of which is 3,000,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 3,000,000. The forfeiture and surrender will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that the Founder Shares will represent approximately 20.0% of the Company’s issued and outstanding Ordinary Shares after the Public Offering. The Sponsor further agrees that to the extent that the size of the Public Offering is increased or decreased and the Sponsor has either purchased or sold Ordinary Shares or an adjustment to the number of Founder Shares has been effected by way of a share dividend or share capitalization, or a surrender for no consideration or share contribution back to capital, or otherwise, in each case in connection with such increase or decrease in the size of the Public Offering, then (A) the references to 3,000,000 in the numerator and denominator of the formula in the first sentence of this paragraph 6 shall be changed to a number equal to 15% of the number of Class A Ordinary Shares included in the Units issued in the Public Offering and (B) the reference to 750,000 in the formula set forth in the first sentence of this paragraph 6 shall be adjusted to such number of Founder Shares that the Sponsor would have to collectively return to the Company in order for all holders of Founder Shares to hold an aggregate of approximately 20.0% of the Company’s issued and outstanding Ordinary Shares after the Public Offering.
7. The Sponsor and each Insider hereby agrees and acknowledges that: (i) each of the Underwriters and the Company would be irreparably injured in the event of a breach by the Sponsor of its obligations (as applicable) under paragraphs 1, 2, 4, 5, 6, 8(a) and 8(b) or by each Insider of its obligations under paragraphs 1, 2, 4, 8(a) and 8(b), (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach.

8. Transfer Restrictions.
