Re: Initial Public Offering

Ladies and Gentlemen:

This letter (“Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and between BM Acquisition Corp., a Cayman Islands exempted company (the “Company”), and ▇. ▇▇▇▇▇ Capital LLC as the representative (the “Representative”) of the several underwriters named in Schedule I thereto (the “Underwriters”), relating to an underwritten initial public offering (the “IPO”) of the Company’s units (the “Units”), each Unit comprised of one Class A ordinary share of the Company, par value $0.0001 (“Class A Ordinary Share”), and one-half of one redeemable warrant (each whole warrant, a “Warrant”). Certain capitalized terms used herein are defined in paragraph 12 hereof.

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the benefit that such IPO will confer upon the undersigned, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned sponsor of the Company, BM Global Capital, a Cayman Islands exempted company (the “Sponsor”) and each of Insiders, as defined below (collectively, the “undersigned”), ▇▇▇▇▇▇ agrees, severally but not jointly, with the Company as follows:

1. If the Company solicits approval of a Business Combination from its shareholders, the undersigned agree that in connection with such proposed Business Combination, it, he or she shall (i) vote all Insider Shares and any shares acquired by it, him or her in the IPO 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 (as defined below) owned by it, him or her in connection herewith

2. (a) In the event that the Company fails to consummate a Business Combination within the time period (the “Combination Period”) set forth in the Company’s Second Amended and Restated Memorandum and Articles of Association, as the same may be amended from time to time (the “Articles of Association”), the undersigned will, as promptly as possible, take all necessary actions 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 business days after the Combination Period, redeem the Class A Ordinary Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of the date that is two business days prior to the distribution date, including interest (net of amounts withdrawn for payment of any income taxes and up to $100,000 to pay dissolution expenses), divided by the number of the then-outstanding Class A Ordinary Shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation 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, liquidate and dissolve, subject, in the case of clauses (ii) and (iii), to the Company’s obligations under Cayman Islands law to provide for claims of creditors and, in all cases, to the other requirements of applicable law.

(b) The undersigned hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Account (“Claim”) with respect to the undersigned’s Insider Shares and Class A Ordinary Shares underlying the Private Securities and hereby waives any Claim the undersigned 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. The undersigned acknowledges and agrees that there will be no distribution from the Trust Account with respect to any Warrants, all rights of which will terminate on the Company’s liquidation.

(c) In the event of the liquidation of the Trust Account, BM Global Capital (the “Sponsor”) agrees to indemnify and hold harmless the Company for any debts and obligations to target businesses or vendors or other entities that are owed money by the Company for services rendered or contracted for or products sold to the Company, but only to the extent necessary to ensure that such debt or obligation does not reduce the amount of funds in the Trust Account below $10.00 per share; provided that such indemnity shall not apply if such vendor or prospective target business executed an agreement waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account.

3. The undersigned acknowledges and agrees that (i) the Company shall not enter into a definitive agreement regarding a proposed Business Combination without the prior written consent of the Sponsor, and (ii) prior to entering into a Business Combination with a target business that is affiliated with any Insiders of the Company or their affiliates, such transaction must be approved by a majority of the Company’s disinterested independent directors.

4. Neither the undersigned nor any affiliate of the undersigned will be entitled to receive and will not accept a finder’s fee or any other compensation prior to, or for services rendered in order to effectuate, the consummation of the Business Combination; provided that the Company shall be allowed to make the payments set forth in the Registration Statement under the caption “Prospectus Summary – The Offering – Limited payments to insiders.”

5. (a) The undersigned agree that they shall not Transfer any Insider Shares until six months after completion of an initial Business Combination, or the date the Company completes a liquidation, merger, capital stock exchange or other similar transaction that results in all of its public shareholders having the right to exchange their Ordinary Shares for cash, securities or other property, and that they shall not Transfer any Private Securities until after the completion of an initial Business Combination.

(b) Notwithstanding the provisions set forth in paragraph 5(a), Transfers of the Insider Shares and Private Securities are permitted (i) among the undersigned or to an undersigned’s member, partner, officer, director, or affiliate; (ii) by gift to a member of the holder’s immediate family or to a trust, the beneficiary of which is a member of the holder’s immediate family or an affiliate of such individual, or to a charitable organization; (iii) by virtue of laws of descent and distribution upon death; (iv) pursuant to a qualified domestic relations order; (v) by virtue of the Sponsor’s or the Representative’s organizational documents upon liquidation or dissolution of the Sponsor or the Representative, as applicable; or (vi) in the event of the Company’s liquidation prior to the completion of a Business Combination; provided, however, that, in the case of clauses (i) through (v), each transferee agrees in writing to be bound by the Transfer restrictions and the other restrictions contained in this Letter Agreement.

6. (a) In order to minimize potential conflicts of interest that may arise from multiple corporate affiliations, the undersigned hereby agrees that until the earlier of the Company’s initial Business Combination or liquidation, the undersigned shall present to the Company for its consideration, prior to presentation to any other entity, any suitable opportunity to acquire a target business, subject to any pre-existing fiduciary or contractual obligations the undersigned might have.

(b) The undersigned ▇▇▇▇▇▇ agrees and acknowledges that (i) the Underwriters and the Company may be irreparably injured in the event of a breach of any of the obligations contained in 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.
