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 Colombier Acquisition Corp. II, a Cayman Islands exempted company (the “Company”), and BTIG, LLC, as the representative (the “Representative”) of the several underwriters (the “Underwriters”), relating to an underwritten initial public offering (the “Public Offering”), of up to 14,950,000 of the Company’s units (including up to 1,950,000 units that may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one of the Company’s Class A ordinary shares, par value $0.0001 per share (the “Class A Ordinary Shares”) and one-third of one redeemable warrant. Each whole warrant (each, a “Public Warrant”) entitles the holder thereof to purchase one Class A Ordinary Share at a price of $11.50 per share, subject to adjustment as described in the Prospectus (as defined below). The Units will be sold in the Public Offering pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”) and the Company has applied to have the Units listed on the New York Stock Exchange. 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, each of Colombier Sponsor II LLC, a Delaware limited liability company (the “Sponsor”), and the undersigned individuals, each of whom is, or will be, a member of the Company’s board of directors and/or management team (each of the undersigned individuals, an “Insider” and collectively, the “Insiders”), hereby agrees with the Company as follows:

1. [Reserved].

2. Business Combination Support. The Sponsor and each Insider agrees with the Company 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 any Ordinary Shares owned by it, him or her in favor of any proposed Business Combination and (ii) not redeem any 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 therewith.

3. Failure to Consummate a Business Combination; Trust Account Waiver.

(a) The Sponsor and each Insider hereby agrees with the Company that in the event that the Company fails to consummate a Business Combination within the time period set forth in the Company’s amended and restated memorandum and articles of association (as it may be amended from time to time, the “Charter”), 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, 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 (net of amounts withdrawn to fund the Company’s working capital requirements, subject to an annual limit of $1,000,000 and taxes payable (“Permitted Withdrawals”) and up to $100,000 of interest to pay liquidation and dissolution expenses), divided by the number of then outstanding Offering Shares, which redemption will completely extinguish all Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), 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 in all cases subject to the other requirements of applicable law.

(b) The Sponsor and each Insider agrees not to propose any amendment to the Charter (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with its initial Business Combination or to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within 24 months from the closing of the Public Offering (or 27 months from the closing of the Public Offering if the Company has executed a letter of intent, agreement in principle or definitive agreement for an initial Business Combination within 24 months from the closing of the Public Offering), or such earlier liquidation date as the Company’s board of directors may approve 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 in connection with any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account (net of Permitted Withdrawals), divided by the number of then outstanding Offering Shares.

(c) The Sponsor acknowledges and agrees that in the event that the Company fails to consummate a Business Combination within the time period set forth in the Charter, it hereby waives its right to be repaid from the Trust Account for any working capital loans in excess of the Permitted Withdrawals to such date, that it or its affiliates or designees have provided to the Company.

(d) The Sponsor and each Insider acknowledges that it, he or she has no right, title, interest or claim of any kind in or to any monies held in the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to any Founder Shares held by it, him or her. The Sponsor and each Insider hereby further waives, with respect to any Founder Shares and Offering Shares held by it, him or her, if any, any redemption rights it, he or she may have in connection with a shareholder vote to approve an amendment to the Charter (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with its initial Business Combination or to redeem 100% of the Offering Shares if the Company has not consummated a Business Combination within the time period set forth in the Charter or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity (although the Sponsor and the Insiders shall be entitled to redemption and liquidation rights with respect to any Offering Shares it or they hold if the Company fails to consummate a Business Combination within the time period set forth in the Charter). The Sponsor and each Insider further waive any claim it may have in the future as a result of, or arising out of, any contracts or agreements with the Company and will not seek recourse against the Trust Account for any reason whatsoever.

4. Business Combination with Affiliate. The undersigned acknowledges and agrees that prior to entering into a definitive agreement for a Business Combination with a target business that is affiliated with the undersigned or any other Insiders of the Company or their affiliates, such transaction must be approved by a majority of the Company’s disinterested independent directors and the Company must obtain an opinion from an independent investment banking firm or an independent firm that commonly renders valuation opinions that such Business Combination is fair to the Company from a financial point of view.

5. Lock-Up; Transfer Restrictions.

The Sponsor and each Insider agrees that it, he or she shall not Transfer:

(a) any Founder Shares (the “Founder Shares Lock-up”) until the earlier of (i) six months after the completion of an initial Business Combination or (ii) subsequent to the consummation of an initial Business Combination, the date on which the Company consummates a transaction which results in all of its shareholders having the right to exchange their shares for cash, securities, or other property (the “Founder Shares Lock-up Period”); and

(b) any Private Placement Warrants, Working Capital Warrants or in each case the Ordinary Shares underlying such warrants, until 30 days after the completion of an initial Business Combination (the “Warrants Lock-up Period,” and together with the Founder Shares Lock-up Period, the “Lock-up Periods”).

(c) During the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the Sponsor and each Insider shall not, without the prior written consent of the Representative, Transfer any Units, Founder Shares, Private Placement Warrants, Working Capital Warrants (or the Ordinary Shares underlying such warrants), or any other securities convertible into, or exercisable or exchangeable for, Ordinary Shares (but excluding Units, Ordinary Shares or Public Warrants purchased in the Public Offering or thereafter) held by it, her or him, as applicable.

(d) Notwithstanding the provisions set forth in Sections 5(a), 5(b) or 5(c) above, Transfers of the Founder Shares, Private Placement Warrants, Working Capital Warrants or Ordinary Shares underlying such warrants that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied with this paragraph 3(d)), are permitted (a) to the Company’s officers or directors, any affiliate or family member of any of the Company’s officers or directors, any affiliate of the Company’s Sponsor or to any member of the Sponsor, any of their affiliates; (b) in the case of an individual, as a gift to such person’s immediate family or to a trust, the beneficiary of which is a member of such person’s immediate family, an affiliate of such person or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection with the consummation of a Business Combination at prices no greater than the price at which the Founder Shares or Private Placement Warrants (as well as the Ordinary Shares underlying such warrants), as applicable, were originally purchased; (f) by virtue of the laws of the Cayman Islands or the Sponsor’s organizational documents upon liquidation or dissolution of the Sponsor; (g) in the event of the Company’s liquidation prior to the completion of a Business Combination; or (h) in the event of completion of a liquidation, merger, share exchange or other similar transaction which results in all of the Company’s Public Shareholders having the right to exchange their Ordinary Shares for cash, securities or other property subsequent to the completion of an initial Business Combination; provided, however, that in the case of clauses (a) through (f) these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions.

6. Indemnification. In the event of the liquidation of the Trust Account upon the failure of the Company to consummate its initial Business Combination within the time period set forth in the Charter, the Sponsor (the “Indemnitor”), which for purposes of clarification shall not extend to any other shareholders, members or managers of the Sponsor, or any of the other undersigned, 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) to which the Company may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company, (ii) any prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement (a “Target”) or (iii) any taxing authority; provided, however, that such indemnification of the Company by the Indemnitor (x) shall apply only to the extent necessary to ensure that such claims by a third party or a Target do not reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Offering Share and (ii) the actual amount per Offering Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Offering Share is then held in the Trust Account due to reductions in the value of the trust assets, in each case, net of Permitted Withdrawals and up to $100,000 of interest to pay liquidation and dissolution expenses, (y) shall not apply to any claims by a third party or a Target which executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) and (z) shall not apply to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended. In the event that any such executed waiver is deemed to be unenforceable against such third party, the Indemnitor shall not be responsible to the extent of any liability for such third party claims. The Indemnitor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Indemnitor, the Indemnitor notifies the Company in writing that it shall undertake such defense.

7. Forfeiture of Founder Shares. To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 1,950,000 Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost, a number of Founder Shares equal to 487,500 multiplied by a fraction, (i) the numerator of which is 1,950,000 minus the number of Units purchased by the Underwriters upon the exercise of its over-allotment option, if any, and (ii) the denominator of which is 1,950,000. The forfeiture 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, on an as-converted basis, an aggregate of 20% of the Company’s issued and outstanding Ordinary Shares upon consummation of the Public Offering. The Initial Shareholders further agree that to the extent that the size of the Public Offering is increased or decreased, the Company will purchase or sell Class B Ordinary Shares or effect a share repurchase or share capitalization, as applicable, immediately prior to the consummation of the Public Offering in such amount as to maintain the number of Founder Shares, on an as-converted basis, at 20% of the Company’s issued and outstanding Ordinary Shares upon consummation of the Public Offering. In connection with such increase or decrease in the size of the Public Offering, then (A) the references to 1,950,000 in the numerator and denominator of the formula in the first sentence of this paragraph 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 487,500 in the formula set forth in the first sentence of this paragraph shall be adjusted to such number of Founder Shares that the Sponsor would have to surrender to the Company in order for the number of Founder Shares to be equal, on an as-converted basis, to an aggregate of 20% of the Company’s issued and outstanding Ordinary Shares upon consummation of the Public Offering.

8. Remedies. The Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriters and the Company would be irreparably injured in the event of a breach by such Sponsor or an Insider of its, his or her obligations under paragraphs 2, 3, 4 and 5, as applicable, of this Letter Agreement, (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.

9. Representations and Warranties.
